DockerCon 2018 - great event (with a small fly in the ointment)

Fri, 07 Dec 2018 12:57:35 -0500

I have just returned from DockerCon Europe 2018 and I’d like to share my impressions while they are fresh in my mind. It was my first DockerCon so I was not quite sure what to expect. As the title says, it was great experience and barring the scaling issue (more below) could have been really awesome experience.

But let’s take things in order. First location - Barcelona. Hard to pick better place in December than Spain. I am sure the Northerners greatly appreciated the break from cold and enjoyed the balmy 15 to 20 degrees. The venue Centre de Convencions Internacional de Barcelona - CCIB - though not located in the centre, is at the shore and one can walk to the beach in 2-3 minutes. There were three of us going from Valencia office (which is 3 hours train ride down the coast from Barcelona) and we had also great hotel experience. I can highly recommend Hotel Princess Barcelona. What can be better than starting your day with watching sunrise over Mediterranean Sea. Thanks David - because you did such a great job, you are now in charge of travel and hotel booking going forward :-D

ATG Module Diagram Generator

Sat, 10 Feb 2018 11:22:48 +0800

I have found local clone of this repo while cleaning up the disk. The source was originally residing in private repo on Bitbucket which I moved to GitHub: https://github.com/miroadamy/atgdiagram

What it does

Groovy scripts:

that scan local ATG installation, discover modules and generate the PlantUML file representing it, for example - https://github.com/miroadamy/atgdiagram/blob/master/uml/test2.uml

Git bits 2

Using the Scala source repo to demonstrate - see Github

Show merged and unmerged branches
#

This command allows you to show all local branches merged / unmerged to current branch

➜  scala git:(2.12.x) git branch -a --merged
* 2.12.x
  remotes/origin/2.11.x
  remotes/origin/2.12.x
  remotes/origin/HEAD -> origin/2.12.x

➜  scala git:(2.12.x) git branch -a --no-merged
  remotes/origin/2.10.x
  remotes/origin/2.8.x
  remotes/origin/2.9.x
  remotes/origin/DarkDimius-patch-1
  remotes/origin/gh-pages
  remotes/origin/legacy/msil

This shows you all local branches merged into named branch:

Git - find unmerged commits

Tue, 22 Mar 2016 12:57:35 -0500

This is Ruby script I found way back and was using it since.

The credits for creation goes to Zach Dennis. The script is decribed in his blog post

The source is here

      |This script wraps the "git cherry" command. It reports the commits from all local
      |branches which have not been merged into an upstream branch.
      |
      |  #{yellow("yellow")} commits have not been merged
      |  #{green("green")} commits have equivalent changes in <upstream> but different SHAs
      |
      |The default upstream is 'master' (or 'origin/master' if running with --remote)
      |
      |OPTIONS:
      |  -a   display all unmerged commits (verbose)
      |  --remote (-r)  compare remote branches instead of local branches
      |  --upstream <branch>   specify a specific upstream branch (defaults to master)
      |  --exclude <branch>[,<branch>,...]   specify a comma-separated list of branches to exclude
      |  --only <branch>[,<branch>,...]   specify a comma-separated list of branches to include
      |  --prune  prompts user to delete branches which have no differences with the upstream
      |
      |EXAMPLE: check for all unmerged commits
      |  #{$0}
      |
      |EXAMPLE: check for all unmerged commits and merged commits (but with a different SHA)
      |  #{$0} -a

Finding unmerged commits in all branches

      |branches which have not been merged into an upstream branch.
      |
      |  #{yellow("yellow")} commits have not been merged
      |  #{green("green")} commits have equivalent changes in <upstream> but different SHAs
      |

      |OPTIONS:
      |  -a   display all unmerged commits (verbose)
      |  --remote   compare remote branches instead of local branches
      |  --upstream <branch>   specify a specific upstream branch
      |
      |EXAMPLE: check for all unmerged commits

      |
      |EXAMPLE: check for all unmerged commits and merged commits (but with a different SHA)
      |  #{$0} -a

Git bit of the day

Mon, 22 Sep 2014 11:22:48 +0800

Question from email:
#

how do I merge 1 file from master -> LIVE

Answer
#

You cannot. Merge operation creates new commit that has 2 or more parents and will always join full histories of the branches.

You can however:

replicate all changes done in single commit to different branch - this is “cherry pick”
take state of single file from different branch into current branch

How to replicate all changes done in single commit to different branch - “cherry pick”
#

Say you have latest commit in master that contains change to two files you need.

ATG Groovy TDD

Fri, 16 May 2014 11:22:48 +0800

Got it working. It is a bit rough around the edges, but functional.

The two components

The are not started via Initial, but that is not a problem.

The script tested:

class ThatsGroovyDude implements com.thinkwrap.twatg.script.RunnableScript {
    atg.nucleus.Nucleus nuc = atg.nucleus.Nucleus.getGlobalNucleus();
    public String run() {
  
       String s = "";
       nuc.configPathNames.each { s += "${it}\n" }
       return "Hello World!\n\n" + s;
   }
}

Folder action to autorename screenshots

I do not want to have ~/Desktop polluted with files. Thus

mkdir -p ~/Documents/Screenshots
defaults write com.apple.screencapture location ~/Documents/Screenshots
killall SystemUIServer

Test the screenshot - it does it

Binding DashDoc with editors and Eclipse

Tue, 31 Dec 2013 00:57:35 -0500

If you use DashDoc (see http://kapeli.com/dash), it can be integrated with editor or Eclipse to allow automatically find selected text in Dash documentation sets:

Sublime Text
#

This is easy - there is DashDoc plugin - https://sublime.wbond.net/packages/DashDoc
The plugin is OS-X specific, because the DashDoc is

Start Package Control (Cmd-Shift-P)
select Install Package (type Install)
select DashDoc

The Ctrl-H does the search

ATG Development using 'hidden' VM

Mon, 22 Apr 2013 11:22:48 +0800

Brief description of my latest setup I use for CPL and LCH - in case I forget it or somebody wants to replicate it.

Inspiration for the setup came from https://www.youtube.com/watch?feature=player_embedded&v=cPt_1Vga-Nk

Motivation - issues with VMs
#

VMs are great - they allow “packaged” dev environment and quick start for the new member of the team. Start a VM on local or remote host, connect with VNC or Remote Desktop and you are in business.

Merge conflict with deleted file

Sat, 13 Apr 2013 11:22:48 +0800

I was merging the branch that removed / consolidated bunch of duplicate JSP files (corporate-ui-cleanup).

In the meantime in master, some minor UI changes were made to these files whose content was now elsewhere.

Quick trick how to resolve it fast:

Show branch
#

CineplexB2B $ git show-branch
! [bb-database-cleanup] Loading data with XML only: no constraints and tax_id (unused field) nullable
 ! [bb-gradle-build] Merge branch 'master' into bb-gradle-build
  * [bb-master] Merged in the last 5 days changes
   ! [corporate-ui-cleanup] Merged in the last 5 days changes
    ! [master] Merged in the last 5 days changes
-----
 -    [bb-gradle-build] Merge branch 'master' into bb-gradle-build
 ---- [bb-master] Merged in the last 5 days changes
 +*++ [bb-master^2] CPLXB2B-562, usageInfo/internalUsageInfo mapping in CFI
 +*++ [bb-master^2^] return order goes all the way to NEW: replaced SetPaymentGroupAmount, added ReturnFee calculator, added reusable jsp fragments for sales order pages
 +*++ [bb-master^2~2] Styling change to avoid disappearing links inside Terms and Conditions
 +*++ [bb-master^2~3] Dealing with consequences if INTERNAL split to INTERNAL_TRANSFER and INTERNAL_PURCHASE
 ---- [bb-master^2~4] Merge remote-tracking branch 'origin/master' into uat2-deploy
 ---- [bb-master^2~4^2] Merge branch 'master' of luke:cineplex-b2b
 +*++ [bb-master^2~4^2^] merged changes - fixed conflict
 +*++ [bb-master^2~4^2~2] CPLXBTOB-557 - fixed amount column to show proper currency
 ---- [bb-master^2~4^2~3] Merge branch 'master' of twgit@luke:cineplex-b2b.git
 +*++ [bb-master^2~4^2~4] CPLXBTOB-484 - fixed the spacing and comma issues
 +*++ [bb-master^2~5] Reverted 4d512ed - issue with recalculate. Must be solved selectively via Javascript
 +*++ [bb-master^2~6] Spacing in header

Pattern for test sourcing the script

Tue, 09 Apr 2013 11:22:48 +0800

# Test if it is sourced or not
if [[ $0 != .*bash ]]; then
    echo Please source it: . $0
    exit 1
fi
res=`gradle --version >/dev/null 2>&1; echo $? `        
if [[ $res == "0" ]]; then
    echo Have gradle: `which gradle`
    gradle --version
else
    export GRADLE_HOME=~/opt/gradle
    export PATH=$PATH:$GRADLE_HOME/bin
    echo No Gradle, adding - `which gradle`   
    gradle --version
fi

ATG Repository item linking and versioned repos

Sun, 10 Mar 2013 11:22:48 +0800

We have versioned repository ClientProvinceRepository that defines discount types based on account category pricelist and accounts - discountTypePriceList

=> (let’s not start discussion why this is not part of the pricelists).

The item definition:

<item-descriptor name="discountTypePriceList" display-name="Discount Type Price List" item-cache-size="1000" query-cache-size="1000" display-property="discountType">
    <table name="CPLXB2B_DISCOUNT_PRICE_LIST" type="primary" id-column-name="DISCOUNT_PRICELIST_ID" >
        <property name="discountType" data-type="enumerated" column-name="DISCOUNT_TYPE" default="Base" queryable="true" category="Discount Price List" display-name="Discount Type" >
              <attribute name="useCodeForValue" value="false"/>
                  <option value="Base" code="0"/>
                <option value="Silver" code="1"/>
                <option value="Gold" code="2"/>
                <option value="Platinum" code="3"/>
        </property>
        <property name="priceListId" column-name="PRICE_LIST_ID"  repository="/atg/commerce/pricing/priceLists/PriceLists" item-type="priceList" display-name="List Price List" required="true" category="Discount Price List"/>
        <property name="salePriceListId" column-name="SALE_PRICE_LIST_ID"  repository="/atg/commerce/pricing/priceLists/PriceLists" item-type="priceList" display-name="Sale Price List" category="Discount Price List"/>
        <property name="startDate" column-name="START_DATE" data-type="timestamp" display-name="Start Date" category="Discount Price List"/>
        <property name="endDate" column-name="END_DATE" data-type="timestamp" display-name="End Date" category="Discount Price List"/>
    </table>
     
</item-descriptor>

When I tried deployment with this, I got error

German attack

Tue, 05 Mar 2013 11:22:48 +0800

Suddenly I started to see all apps auf Deutsch:

The cause was by mistake selecting additional language in Properties -> Internationalization (Österreichisches Deutsch) and the system added it to the list as language #1.

Those programs that are localized, picked it up ….

Here is how that list looks like after reorder :-) I care only for the first 11 languages anyway ;-)

Performance issues with Quicklook in OS-X Lion

Sat, 23 Feb 2013 11:22:48 +0800

I have been experiencing issues with Quicklook (press Space on file in Finder or Pathfinder) for some time: it took several second, sometimes 10-15 to show content of simple 1K large property file.

It turned out that on of the QuickLook plugins, installed originally way back in Leopard and brought ahead with TimeMachine restores could have been the reason: the QLStephen.

For more on that plugin see:

To remove the plugin, go to ~/Library/QuickLook and delete the file (it is the bundle) QLStephen.qlgenerator.

Discovered Trello

Mon, 12 Nov 2012 11:22:48 +0800

Finally a todo/task/project management system that is very good fit.

Here is why:

is pretty visually
modern and dynamic UI
has Web back-end (usable from Linux VM)
has decent iPhone app
allows checklists (multiple)
allows color coding
Markdown support
ecosystem

There is Gmello that allows create card from GMail, plus few others that seem to bridge the gap between Evernote, System XYZ and Trello

Custom build of MacVim with file drawer - pure bliss

Sun, 07 Oct 2012 11:22:48 +0800

OK, NERDTree plugin IS great, but this is awesome.

Alloy made custom version of MacVim with file drawer: see https://github.com/alloy/macvim/wiki/Building

It is available in source - so you have to compile it yourselves. But if you do not want to, I did it and the binary is attached, built with these features:

./configure –with-feature=huge –enable-rubyinterp –enable-pythoninterp –enable-perlinterp –enable-cscope

Archive is attached: MacVim.zip

If you want to get my set of plugins and customizations, it is on GitHub: - https://github.com/radegast/dotvim,

I had to add user madamy to my public GitHub repo - where I keep the dot-files - https://github.com/radegast/dotvim

This may be an issue for people that have their own private accounts - the key management is the key.

This article is useful:

Alternative

Use https for forking , instead read/write ssh. No keys involved there

Using MacVim as git editor

Mon, 09 Apr 2012 11:22:48 +0800

Add this to .bashrc
#

export GIT_EDITOR=’/Applications/MacVim.app/Contents/MacOS/Vim -g -f '

The key is -f, without it git will abort because of empty commit message.

How to make unregistered files work in Quick View on OS-X

Sun, 08 Apr 2012 11:22:48 +0800

Out of the box Quick View (press Space in Finder) behaviour on unregistered files is not very useful: it shows huge Unix icon instead of content of file.

This is default for files like Makefile or build.gradle

This plugin makes it go away and show text file for all UTIs that are plain text: http://whomwah.github.com/qlstephen/

Installation:

open the DMG file
copy QLStephen.qlgenerator to /Users/<<USERNAME>>/Library/QuickLook/QLStephen.qlgenerator

That’s it.

Now it looks like this:

Few gitbits to remember

Few gitbits to remember
#

Pushing new local branch to remote repo:
#

Find a ref that matches experimental in the source repository (most likely, it would findrefs/heads/experimental), and update the same ref (e.g. refs/heads/experimental) in origin repository with it.

If experimental did not exist remotely, it would be created.

Tomcat 5 not reloading changes in JSP

Sun, 24 Jul 2011 17:33:34 -0400

Part of the beauty of JSP development is the easy of trying out the change. All you have to do is edit the JSP file, save it and reload the page. Yesterday I got caught by surprise by not being able to do exactly that. I saw some strange behaviour in an EL expression used JSP tag. As it was nothing ATG specific, I decided to try it out in plain old Tomcat rather than full ATG application. So I located the instance of Tomcat 5.5 (I always have couple of Tomcats lying around) and being lazy, I decided to inject the change into out-of the box jsp-examples Web application that comes with it.

Dear Cultured Code, you are history ...

Sat, 18 Jun 2011 23:16:36 -0400

I have been Cultured Code customer for over 2 years and used multiple their products: Things on OS-X, Things for iPad and iPhone on daily basis.

Not any more.

I am definitely giving up on Things and Cultured Code products.

The reason why is sheer frustration from long wait on usable synchronization between Things on Mac, iPad and iPhone. Something that have been discussed, promised, chewed over 2 years and that still does not work.

Better GMail than GMail

Fri, 11 Feb 2011 23:38:05 -0500

Since 2005 when I switched to GMail, I was living in browser. For better or worse, I learn to put up with issues like speed, lack of hotkeys, UI that is not as responsive as it should be, drag and drop that works most of the time. To be fair, in these five years browsers and GMail UI improved tremendously. It was rational decision to trade all these for simplicity of the UI.

Podcast recommendation

Wed, 24 Nov 2010 00:13:10 -0500

I have find new podcast that I want to share with you. It is called "This Developer's Life" and is produced by well known digerati Scott Hanselman and Rob Conery.

I listen to a lot of podcasts, about 50 % of them produced by Leo Laporte's TWIT Network (This Week in Tech, Macbreak, This Week in Google, FLOSS Weekly and occasional Security Now).

What I like about Leo's network is professionalism of audio production, usually good and interesting panel with topics that are worth listening to. Few other podcasts come even close to the TWIT level of perfection.

One month with Windows 7

Mon, 25 Jan 2010 10:33:35 -0500

It has been one month now that I started to use Windows 7 based Dell Vostro 1320 notebook on daily basis. The hardware parameters of this little thing are: Core 2 Duo 2.26, 500 GB HDD, 8 GB of RAM, 13" screen, Windows 7 Professional (64 bit of course, how else with all that RAM). All this with 3 year next business day warranty for about $1400 CAD - not bad deal at all.

Cure for crashing FourSquare and RunKeeper on iPhone

Mon, 11 Jan 2010 00:29:18 -0500

Few weeks ago, first Foursquare application and then my favorite RunKeeper app started to fail. The symptoms were simple:

1) attempt to start

2) wait for for 2-10 seconds

3) exit

Analysis of the crash logs did not reveal anything obvious (see ~/Library/Logs/CrashReporter/MobileDevice/NAME:

What helped was to delete both applications from the phone, including data and let the iTunes install it back. No data is lost, because both services are cloud based - only minor inconvenience was to re-enter login information.

Facebook domain type-in hack

Fri, 24 Jul 2009 19:00:56 -0400

You know the drill: open browser, new tab, type 'www.facebook.com' and in moment you can see who of your online buddies is up to something interesting. This is exactly what I did. Only I did not end up in well known Facebook page, but on something really fishy:

This is definitely NOT facebook. How come I ended up on 'quiz.us' site when I typed in www.facebook.com. Or did I ? Let's do it again:

Microsoft Office 2008 vs NeoOffice vs iWorks'08

Tue, 28 Apr 2009 21:58:10 -0400

I was happy user of the iWork Suite 08 since I moved to OS-X. It somehow better matches the way I am thinking and does much better job than Office to get me from idea to acceptable looking rendering of that idea in the form of document, spreadsheet or presentation.

In past two month I was involved much more interaction with the requirements, business analysis and project management part of the process. Which inevitably means much higher exposure to documents creation, collaboration and exchange. iWork gives you reasonably good compatibility with Office document formats, which means that you can easily import almost every Office document modify it and export it back so that Windows user will see almost all of your changes. Almost everything will be just fine. Unfortunately, almost is not the same as everything: it often breaks fine details of formatting, reviewer comments and does not really work for more complicated Excel spreadsheets. Especially those spreadsheets which project manager-ish people so love to create.

Bye bye Ruby, hello Groovy

Tue, 17 Mar 2009 19:08:35 -0400

I first time discovered Ruby back in 2006 (yes, I know, I was late to the game), and immediately fell in love with it. The dynamic nature of the language, the consistency, pure esthaetics and practicality certainly changed the way how I saw software development and programming languages.

Since that time, I made several attempts to integrate Ruby into my professional life and make it part of the toolbox. It was cool to play with Ruby in my spare time, but I wanted to use it on projects whose main development language/platform was mainly Java. Use it as scripting, glue language. Use it as toolkit language to e.g. generate test data, access databases, convert files, build projects and maybe even build a piece of Web applications (admin apps for example).

It's alive !

Wed, 18 Feb 2009 20:26:22 -0500

I was aching to blog about this since December 18th, when our system quietly and gently slipped into public visibility. Marked as Beta (thanks, Google for making this a legitimate way how to go live) it comfortably made it through Christmas shopping season into 2009.

Now when the site has been announced and mentioned few times in the media, I guess it's OK to mention it here too.

What is "it" ? A new, fresh eCommerce site selling music. A lots of really good music. Without any DRM or any other nonsense, as plain good high quality (mostly 320 kps) MP3's. The selection is actually very good - starting from several hundred thousands in December to several few million songs when full catalog is loaded. More great music being added every week.

How to un-stuck unsuccessful OS-X upgrade

Sat, 07 Feb 2009 11:19:49 -0500

Here is the context: in order to upgrade iLife 08 to iLife'09 (which is very nice, btw), I had to install 10.5.6 upgrade. And according Murphy's law, one of the 2 GB DIMM's in my MacBook Pro went bad exactly during the OS-X upgrade process.

It had two rather unpleasant consequences:

some of the patch files got downloaded and saved in corrupted state

The machine did not boot back after restart

The second problem was fixed by replacing the bad DIMM, but the first caused that upgrade to 10.5.6 was impossible: the files were downloaded, verification failed, after restart I was back to square one. There was no obvious way how to "undownload" the files.

VMWare and slow clocks - take 2

Fri, 09 Jan 2009 14:37:46 -0500

The centos 4.x we are using as platform for the VMWare VMs (yes, I know there is version 5, but we need to be compliant with RHEL 4.x because of the ATG requirements) installs by default the NTP client.

Here is sequence of steps that needs to be performed to enable automatic synchronization of the clocks.

make sure the DNS works

cat /etc/resolv.conf
sudo vi /etc/resolv.conf

and check that nameservers point to something meaningfull, e.g:

VMWare and slow clocks

Sun, 04 Jan 2009 23:51:35 -0500

I have noticed recently that most of our VMWare instances (and we are running decent fleet of them for the ATG Lab as well as internal system) if left without time synchronization, will loose get late quite a bit: some of them as much as hour or more a week.

Unix date command unfortunately belongs to those commands that I am having troubles to remember and everytime I have to use it with parameters, I end up googling for examples ...

Sane version of Twitter

Tue, 18 Nov 2008 01:17:26 -0500

Since few weeks we have started internally use an interesting microblogging tool named Yammer. It works very similarly to Twitter, which means that you are posting very short posts, focusing on the stuff you are doing or working on. Unlike with Twitter, Yammer is company oriented and your posts will be visible ONLY to the recipients that share your company's email address.

Yammer is free service with interesting business model: everybody can join your company's network (if that person has proper email address), but to gain administrative rights, you have to pay dollar a month per user. I actually like this approach because it gives hope that the service will be around and available next year :-)

VMWare Converter error P2VError UNABLE_TO_DETERMINE_GUEST_OS

Sun, 19 Oct 2008 17:34:26 -0400

This was error I have received while trying to convert physical machine running Windows 2003 SP1 into VMWare image.

After some googling around and experimenting (this link was most helpful to point me in correct direction) I found solution that worked for me.

All I had to do was to disable Floppy Drive in the System applet of Control panel. After this, the conversion continued and right now is squeezing 100 GB disk into 50 2 GB files on external USB disk.

Project Management - in a Nutshell

Tue, 30 Sep 2008 21:56:55 -0400

A wonderful gem I found here:

I remember telling a friend
that being a project manager
is a little like being a bouncer:
where there's a problem *here*
and a door *there*
and it's your job to get the problem out the door.

So
For some a gentle gesture will do
while others need a push
and still others need to be picked up by their pants and carried

Free eBook on ALT.NET

Sat, 27 Sep 2008 20:04:01 -0400

It is always a nice surprise to find something that is free and actually useful on the Net :-). Like this one: a fellow Ottawan Karl Sequin wrote and generously made available as free download "Foundations of programming" eBook.

He touches many topics of various levels from high level design concepts (dependency injection) to low level "Back to Basics" - how memory allocation and pointers work. Especially the later is often neglected and overlooked (and consequently misunderstood) by younger developers who started their education with a garbage collected language such as Java or C# and never were exposed to beauty and horrors of C ;-)

After the Spring Storm

Thu, 25 Sep 2008 23:58:54 -0400

Few days ago, I have received an email asking to attend the SpringSource conference and offering $300 discount if I decide to buy before end of month. The timining was pretty ironical, considering the recent contraversy about SpringSource Entreprise Maintenance policy change. The was a heated discussion on TheServerside.com and even FAQ was compiled by Rod Johnson to explain the whole thing.

So what is the issue: SpringSource, commercial entity behind community driven Spring Framework decided to capitalize on the investment and push the community toward paid service suport contract. Whether or not it was related to funding round and VC's entering the game, is not important. Unfortunately, the terms were not really well explained and SpringSource did initially very poor job explaining and communicating the actual change. The community overreacted and lot of people started to call for code fork, project Summer or similar - or switching to different framework.

Three great Git resources

Before I forget :-)

1) The Git Magic

2) Two git books Pragmatic Git Book and Git internals - nice complement each other

3) Linus Torvalds slightly offensive and very funny talk at Google

in addition to great, precise but not necessarily most digestable manual ...

Calendar synchronization between iPhone, Google calendars and iCal

Tue, 09 Sep 2008 02:08:08 -0400

Here is my situation: I am using three different Macs (Macbook Pro and two iMacs - one at home and occasionally second one at work) and need to keep the contacts and calendars synchronized at least between two of them (MBP and home iMac). I use iPhone which also has calendar and contacts. And in the cloud, there is Google calendar. Actually, more than one: my own calendar and company shared calendar of my colleagues from Thinknostic. Quite a challenge to keep it all in sync.

Objective C: I really miss namespaces

Tue, 02 Sep 2008 23:33:30 -0400

One feature that I strongly miss from Objective C are namespaces. Inability to avoid name clash between your classes sometimes really stands in your way.

I am reading S. Kochan's book "Programming in Objective C" and in one of the examples he creates the class Point. Unfortunately, there already is struct Point defined in mactypes.h.

The solution is easy - rename the darn Point to something like TKPoint ... at least that is what Cocoa naming guide recommends. It is probably matter of getting used to it - but I still find the solution suggested by Kevin Hoffman much more elegant - too bad it is only theoretical. Much nicer than NSHack ;-)

XCode annoyances

Mon, 01 Sep 2008 22:34:57 -0400

I have started to seriously play with Objective C and XCode about week ago. So far it was very pleasant experience. I really like the language - feels like Ruby (or Smalltalk if you want) with rocket launcher: very powerful, blastingly fast and dangerous like hell. No array boundary checks as in Java :-).

The XCode was not bad experience either. Here my very long Eclipse and Visual Studio history is going a bit in the way, as the things often works quite different. Not necessarily worse, but different. It would be too early to judge it - not before I get more proficient in both Objective-C and XCode and learn more Cocoa goodness.

Easy access to log files

Mon, 25 Aug 2008 22:04:04 -0400

Here is the scoop: I need to provide access to multiple log files spread across multiple directories of multiple machines. For example - the JBoss log files and nohup.out, ATG log files, and so on - so that the testers can see what happened on server side when something looks fishy on front end.

One option would be to write a document that contails IP’s of the machines, create user accounts, make sure that they have just enough access rights to see the files but not disturb anything else …

iTunes AppStore update chaos

Wed, 20 Aug 2008 03:08:51 -0400

I just noticed strange thing: it is most likely unrelated, but it happened right after installing 2.0.2 firmware.

The count of updates for AppStore applications is pretty chaotic. You can see different number of updates when looking into different parts of iTunes. I have noticed this cycle repeating for 9 updates, then 8 and so on - here is how it looked when I got down to 3 un-updated apps after few rounds.

iMovie 08 and mystery of disappearing Project Library

Tue, 13 May 2008 01:12:49 -0400

As if the yesterday's Firmware update issue was not enough, I had very strange experience with iMovie 08. Suddenly, for no obvious particular reason the user interface became very unresponsive, I was not able to select project in project library. Switching Event library and Project windows on or off stopped working. Windows were not redrawn properly. Creating new project had no visible effect. I could not click on project to select it (well, technically I *could* click, but nothing happened). The time sliders in Events and Projects were either disabled or invisible ...

Cocoa Programming for Mac OS X, Third Edition is out

Sun, 04 May 2008 10:53:06 -0400

as long as you are Safari Books online subscriber - see it here.

Completely updated with XCode 3.x and Objective C 2.0. The screenshots even show the iPhone project templates, indicating the XCode 3.1 in some places. So far the only difference against reality I have found is not covering the XIB resource format (which is generated by default) and sticking with NIB. This blog entry has good explanation of the difference.

Quick online diagramming tool

Mon, 28 Apr 2008 21:28:22 -0400

I am using OmniGraffle for most of my diagrams. OmniGraffle is an OS-X platform replacement for Visio - only easier to use and better looking (in my opinion). On rare occasions I do not work on my notebook, it is quite useful to have free alternative that allows to create a diagram that does not look too awful, without going through the hoops of downloading and installing software. The bubl.us is exactly that tool.

A false "hang" of Finder

Thu, 24 Apr 2008 00:19:22 -0400

Yesterday, I have noticed interesting thing related to Finder and "beach ball of the death". Suddenly, for no obvious reason, the top menu became unavailable and cursor changed to beachball every time I moved it there. The Bluetooth mouse stopped responding. Finder stopped responding. All symptoms as if Finder would hanging ...

The cause of the issue was crash of unrelated application (iShowU, if you are curious), which brought up the crash report window. For some reason - maybe because it happened while changing spaces - the window was not visible.

Agile development team member mantra

Mon, 21 Apr 2008 00:24:41 -0400

Introducing code review and pair programming has often an impact on relationships in the team - especially when a critique needs to be delivered. It takes great degree of experience on both sides to communicate defects in the code for both the reviewer as well as for the code author to get something useful out of it.

I found this at http://www.finetix.com/blogs/finetixblogs.html which can be helpful (page is 404-ing now, but I luckily saved it in Google Docs way back) :

Weird kind of spam that passes through Akismet

Sun, 20 Apr 2008 18:24:19 -0400

Spam has always been a big problem for all blogs. Fortunately, worpress.com provides wonderfull Akismet spam filter which is works amazingly well. I do have switched on moderation for all comments, to make sure no spam gets through, but without Akismet it would be impossible to manage it because of the spam volume. Since I started this blog (August 2006), it caught over 17'000 (yes, seventeen thousands) spam posts. In other words, about 30 spam comments a day or almost 60 spam comments per published post.

Trying out Groovy with Oracle database

Mon, 07 Apr 2008 22:44:17 -0400

There is a saying that necessity is the mother of invention. Such necessity happened last week and forced me to try out the Groovy language.

The trigger was need for creating good data set for testing changes in a full text search. I had to locate few hundred of obsolete technical documents to be used as test data, dump the metadata as well as the BLOB data to disc, create INSERT sql scripts and loader that would from Ant pre-load the database with the test set and insert the BLOB's. It is fairly simple task, the issue were boundary conditions:

Rails 2 - really good tutorial

Tue, 25 Mar 2008 23:09:55 -0400

Akita published two part tutorial that leads you through building the famous 15 minute blog application in Rails 2.0. Read the parts one and two - or follow the screencast by the same author.

Thanks a lot, Akita - very nicely done !

The meaning of ORA-29907 error and the fix

Wed, 19 Mar 2008 23:17:52 -0400

I have first time encountered the error:

ORA-29907: found duplicate labels in primary invocations

after testing the change request we have implemented recently. The error message was not very helpful - I was not exactly sure which labels and which invocations ;-) - and as Oracle guru who actually does understand fine details of Oracle Text was visiting sunny India, I was on my own.

The change addressed an issue in repository search: users were asking for more flexible processing of full text search phrases: instead of e.g. searching for "unit test" search for document that contains both unit AND test. The text was parsed in Java and the SQL generator produced instead of something like

Starting Ruby on Rails 2 with Netbeans and AWDWR book

Mon, 17 Mar 2008 20:11:08 -0400

After some break, I got back to Rails land. The return is not as smooth as I hoped: since Rails 2.0, many things work differently and quite a few steps learned from "The Book" do not work any more. The issues are more often than not quite easy to fix, but there is quite a few of them.

All the following is related to NetbeansRuby build 6327 from Jan 26th with JRuby 1.1RC1

Showstopper issue with JRuby ?

Sun, 16 Mar 2008 23:36:26 -0400

After some break, I dusted off the Ruby to try out one interesting idea Peter presented yesterday that literally ASKS for Rails. So I grabbed the latest and greatest RubyNetBeans from Ruby Hudson. For some reason it stopped updates on January 26th so the latest version I have got was build 6327. It is bundled with JRuby 1.1RC1 and the Rails version that comes preinstalled is 1.2.6. Using the menu Tools -> Ruby Gems, they can be easily upgraded to latest and greatest 2.0.2.

Couple of Objective-C and Cocoa links

Wed, 12 Mar 2008 23:25:46 -0400

Lured by the iPhone platform, this is what I read in the evenings. Feels kind of funny: after 10+ years of Java/C# and almost as many years of C++ beforehand, I mostly lost my C instincts and C habits. Fortunately, I have also mostly lost my C++ bad habits as well.

The Apple site is definitive starting point - put the http://developer.apple.com/referencelibrary/index.html into your bookmarks. From non-Apple sources, very bookmarking-worthy is the Cocoa Literature and Cocoa Devcentral.

Versioning with Spring and Ant

Mon, 10 Mar 2008 21:11:33 -0400

This is post is NOT about version control in the sense of source code control. It addresses the issue how to easily tell which version of the Web application is running as well make sure that the same version is reflected in the snapshots performed by Ant. We have used this approach on several applications and found it quite useful.

The version I talk about is not the automatically generated version from VCS system (such as SVN revision). The version number is set manually.

iBatis, Date null values and Oracle

Fri, 07 Mar 2008 23:36:09 -0500

I better blog this before I forget what was the issue :-).

During daily run of unit tests, I started to receive this (very well explained) exception:

How to generate and send emails using Spring and Velocity

Wed, 05 Mar 2008 23:29:38 -0500

Testing applications that communicate using email is more challenging than e.g. testing database access. Thanks to GMail and Spring, it can be done pretty easily.

Here is the scoop: I need to generate email notifying users about business events and after sending the email, store the content in the database. In real environment you will use corporate SMTP server and real email addresses of real people.
For development we can avoid bothering and spamming our customers by few simple tricks.

Spring PropertyPlaceholderConfigurer with Velocity

Mon, 25 Feb 2008 23:24:11 -0500

Part of the configuration magic is (one of several) Spring post-processors, that allows load the property file or files and refer to the values in these files inside XML configuration files. The rationale behind these is that property files are much easier to edit that possibly huge XML config file and using property values prevents repeating same value over and over again. With this approach, the following configuration:

Oracle SQLDeveloper and mystery of the missing host

Sat, 23 Feb 2008 09:48:07 -0500

If you work with Oracle database, a very good tool you should not ignore is the Oracle SQL Developer. It gives you much more power when it comes to manipulating data or managing database. I use most of the time MyEclipseIDE plugins, but when I need e.g. export data, the SQLDeveloper is way to go.

Today I tried it for first time on the Mac. I started to configure and database connection and was completely confused by the error message "Port must contain numerical value". Here was the dialog box:

Spring Framework - the biggest missing piece

Mon, 04 Feb 2008 22:04:18 -0500

I am having the pleasure working with Spring 2.x since about October last year. It is my return back to Spring, after first encounter in 2005 (counting only larger projects). Same as in previous project, it has been so much fun :-). So much fun in fact, that I was spending my evening playing with code and reading up what is new in 2.5, rather that blogging ;-)

I am still amazed about how nice is the whole thing designed and how many ways it can be used. It's flexibility is simply breathtaking. The price for the flexibility is complexity - sometimes it is not obvious what of many options should be chosen and what are all these options anyway :-).

Spring 2 MVC and ResourceBundleViewResolver problem

Thu, 24 Jan 2008 23:12:57 -0500

This one took some time to figure out - it is one of those problems that are obvious after you know the solution but hard to see beforehand.

I had the ResourceBundleViewResolver configured with Tiles 2, like this:

[code language='xml']

[/code]

and the view.properties was:

[code language='xml']
parent-view.(class)=org.springframework.web.servlet.view.JstlView
parent-view.(abstract)=true

about.url=https://miroadamy.com/WEB-INF/jsp/about.jsp
form.url=https://miroadamy.com/WEB-INF/jsp/form.jsp
list.url=https://miroadamy.com/WEB-INF/jsp/list.jsp

[/code]

It kept givin exception saying that /WEB-INF/jsp/list.jsp does not exist. Which it did. I tried couple of things, no result.

Using iBatis with Abator

Sun, 20 Jan 2008 23:02:44 -0500

I am back to Java and on mission of re-discovering Spring coolness - and in awe how much was added since 1.2 to current 2.5.1. Thanks, SpringSource and hundreds of contributors.

Data layer of the current project is based on iBatis and Spring DAO. We have decided to try out the Abator tool from Apache (part of the iBatis suite) to generate initial version of data mapping (as we inherited the database schema).

Only necessary part is abator.jar (there are no other dependencies).

JRuby - keeping your database.yml really DRY

Thu, 03 Jan 2008 11:15:26 -0500

I am experimenting in JRuby and use database in virtual machine (VMWare Fusion). This is great because you can have multiple versions of multiple databases ready without polluting the notebook. One downsize though is that IP address of the database will change between the VM restarts.

First important setting in Fusion is to use the 'NAT' option rather than 'Bridged'. With NAT, you database host IP address will not follow the network. It was quite annoying to change it from 192.168.X to 192.168.Y everytime I reconnected at home from work or vice versa.

JRuby trunk - issues with JDBC connectivity

Joel's gems

Thu, 20 Dec 2007 01:51:31 -0500

One of the most readable, original blogers out there, writing on software development practice and techniques - Joel Spolsky - published an excellent 3 part Talk at Yale: Part1, Part2 and Part3.

You will find out:

- what two computer science courses were most useful in his university studies
(one that was not really a comp-sci and one he decided to drop)
- why is it tough to be an in-house programmer
- why is the quality of many in-house systems so bad
- what is this "quality thing" anyway
- why is specification futile

Great Spring blog

Wed, 19 Dec 2007 15:42:54 -0500

in case you have not noticed - Interface21 aka SpringSource (great name change, btw) runs a blog with lots of hidden treasures inside.

Recent article describes new addition to Spring portfolio which is territory within my "watched space": enterprise integration. See the blog entry for more.

If you are in corporate space that is keen on "standards", the comparison of Spring vs EJB3 is very good article as well. Not that EJB would matter too much these days (IMHO) - but a nice read nevertheless.

So back again - different coffee shop (Starbucks at Carling), freshly charged battery, Grande Latte and no internet connection (which means no distractions from emails and the Web) - here we go again, part 2.

If I should single out one or two technologies that I think I have neglected and should have paid much more attention to it would be the Web trio of HTML/JavaScript/CSS as one and the SQL as second.

An advice to a fellow developer - 1

Wed, 12 Dec 2007 23:55:20 -0500

We are recently interviewing quite a lot in anticipation of the great things coming. It is sort of similar task as we did year and something ago, but I enjoy this round much better. This time, rather than "we have to assemble the project team ASAP", we have the luxury of longer term view and focus more on hiring the people that will be great match to the company culture, will be with us for longer period and will grow with the company.

Excellent comparison of C++ and Objective-C

Sun, 09 Dec 2007 13:56:03 -0500

One of the languages that I managed to completely ignore for almost 20 years was Objective-C. I always saw it as less developed, dead-end version of C++ that has little perspective - despite that GCC supported it since early days. I guess I was wrong on two of three counts - that of little perspective still holds as long as you want to stay outside of OS-X platform.

One of the issues I had was strange syntax and that from not too many books on subject, they were

Taking the pain off installation

Sat, 08 Dec 2007 19:31:52 -0500

I was trying to set up an Oracle appliance - install the Oracle Express XE into a virtual machine. What (in my mind) should be smooth and straightforward process was something very different. I should have been forewarned warned after seeing the discussion ... To make long story short, the installer failed on three different Linux VM's I had available - because of unavailable dependencies, too small swap space etc, etc.

Little pains of switching

Thu, 22 Nov 2007 23:31:34 -0500

I have been running the Unix only workstations for over a week now. During this week, I have managed to clean up and convert two Windows boxes to VMWARE virtual machines, but actually had to resort to use the VM's only in two cases. Everything else worked just fine.

The first case was requirement to review an non-trivial Excel file. Normally, Numbers does very decent job when it comes to loading Excel files and for the most the remaining cases, the OpenOffice (in it's more polished Cocoa version NeoOffice) works just fine. Well - as long as you do not open spreadsheet with pivot tables. In my case, the spreadsheet contained pivot tables and charts based on these tables. Numbers warned during import that this feature is not supported and the converted spreadsheet was very good looking - nicer that in Excel, but not quite so functional :-). Strangely enough, the charts were imported OK but lost the drill-down capabilities. After trying out the NeoOffice, the imported spreadsheet had retained some pivot capabilities of the original, but lost charts completely. The only resort was falling back to Office 2003 in virtual machine and using Excel. Fortunately one of the two VM's created from old hardware had Office 2003 installed, so that worked out OK.

My Essential OS X toolset - part 1

Mon, 12 Nov 2007 23:23:53 -0500

Last year, when I got my first Mac, it was a wild ride of discoveries and trying out new software. As result I have ended up with many programs installed that I do not really need or use. Fortunately, the uninstall process is as simple as install and there is no registry that could get corrupted, so it was not really a big deal. With the new one, I am going to be much more selective what I put on the harddrive and what not.

Ragioni per fare il grande salto

Fri, 09 Nov 2007 23:51:28 -0500

During the vacation, we stopped in small bookstore in Verona which was selling computer software as well. At the entrance, there was a poster showing smiling Finder's face, Apple logo and announcing reasons why you would want to make the big jump - il grande salto - to Mac platform. That is to explain the title :-)

Grande Salto is exactly what I did. Without too much preparation or notice. Since Tuesday evening I am happy owner of the beautiful piece of hardware (17 inch 2.4 GHz Core 2 Duo Macbook Pro with 250 GB HDD and 4 GB of RAM) that is greatly complemented by the amazing software collection (OS X 10.5, iLife 08, iWork 08 and many others) running on it. I spent Wednesday playing with it and between 'Wows' and 'Ahhs' managed to setup the core applications I need for work: several configurations of Eclipse (with and without MyEclipseIDE), Netbeans with Ruby, couple of gems and of course THE editor. Then transferred the sources, installed Ant, Spring, Tomcat and couple of opensource packages (e.g. Jakarta Commons). And on Thursday, I jumped right into the field, to the client continuing in development of my current Java project in the place where I left it on Monday with Fujitsu N5100 running XP-ProSP2. As a plan B, I had my old notebook also with me - but did not have to resort to using it.

Installing ATG on Fedora Core

Thu, 08 Nov 2007 15:56:30 -0500

Trying to install ATG on the Linux platform turned out to be not completely hickup-free. The default installer died with the following message:

    $ ./ATG2007.1.bin>
    Preparing to install...>
    Extracting the installation resources from the installer archive...>
    Configuring the installer for this system's environment...>
    awk: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory>
    dirname: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory>

    dirname: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory>
    basename: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory[/sourcecode]>
    Fortunately, the fix was easy after I found out what went wrong: incorrect assumption about kernel version. To make it work, this "hack" helped:>
    [sourcecode language='css']>
    $ mv ATG2007.1.bin ATG2007.1.bin.orig>
    $ cat ATG2007.1.bin.orig | sed "s/export LD_ASSUME_KERNEL/#xport LD_ASSUME_KERNEL/" &gt;ATG2007-1.bin

None of this of course happens on Windows - oh, yes - the joys of not swimming with the crowd :-). You will encounter issues otherwise unknown - but also learn something in the process.

On hardwood floors and software engineering

Mon, 05 Nov 2007 22:57:12 -0500

I am in the middle of a non-computer related project. Last week we have decided to get rid of carpeting in my home office and library and to put in the hardwood floor. My wife picked the wood and color, I picked the contractor, with my son's help we moved out the furniture and the renovation started. The most painful thing was shutting down and disconnecting all the computers and servers - only the lonely router is hanging on the wall and suffering the dust and noise of the power tools. As result, my family is now server-less and until we finish and connect them back, we have to survive using the notebooks only. Fortunately, I have at least one notebook available for each household member, except the cat. Even more fortunately, she (the cat) does not mind.

Missing Java 6 on Leopard - is sky really falling ?

Wed, 31 Oct 2007 00:00:08 -0400

Since the big meow on Friday, lot of unhappy people had been talking and blogging about how terrible and unacceptable is the absence of the Java 6 from the Leopard. Some post were sounding very dramatic "I would not buy Mac if I only knew ..." - which is a bit silly. The Leopard's 300 new features were posted and touted and hyped for two weeks. Some of the "great" improvements were actually fairly modest improvements - so it was OBVIOUS that Java 6 is not going to be included because it would definitely make the list. QED.

One model for popular writing is that it panders to the reader's prejudices. Plain and simple. People like writing that validates them and especially their ideas.

Reading source code considered harmful ?

Wed, 17 Oct 2007 00:15:14 -0400

Every software developer will tell you how frustrating it is to trace problem in your application up to the point of third party library call (jar file or .dll / .so - make your choice) - and then have to resort to trial and error exploration, because you have no source code for that particular library module. For this very reason, most developers always prefer working with libraries or toolkits that comes with source code attached - if they have a choice. As a side benefit, these libraries are often free as a beer as well - but being able to understand the module is much more important as whether you have to pay license fee ...

The craziest requirement I've ever heard about

Mon, 15 Oct 2007 23:12:46 -0400

Can you imagine a database table with 25000 (twenty five thousands) columns ? No, not rows, COLUMNS ! Now if you can do that, can you imagine displaying these columns in a datagrid (spreadsheet) on a screen ?

This is exactly what this guy is describing to be his requirements. I hope he did misunderstood or misread the requirements, because displaying 25000 columns on a screen is not only impossible - it is absolutely useless. How would the user interaction look like ? As one of the guys in the discussion pointed out, the table would be few hundred meters wide (assuming 1 cm cell and 19 inch monitor) ....

The book download page is here, no strings attached - all it will cost you is disclosing an email address (book download link will be emailed to you) and bandwidth to get the 20 MB PDF. Mine is downloading right now, so I cannot tell anything about the book yet. It has 447 pages and from the table of content it looks like solid beginner's book.

Petstore for Ruby/JRuby

I'm speaking here for the Rails (JRuby) side:
there is actually a petstore, it can be found there:

Ruby is in top ten programming languages

Sun, 30 Sep 2007 23:04:14 -0400

According to the TIOBE Programming Community index (which gives an indication of the popularity of programming languages), Ruby jumped 3 places and made it to top ten. Congratulations !

If you look closely on the trends down on the page, the dynamically languages popularity has risen over 3.6% during year period. Which is A Good Thing (TM).

Should I make my personal Top Ten of the programming languages, ordering languages by my degree of comfort of using the language, the language beauty (which is, in the eye of the beholder ;-)). Factoring in also how much I do enjoy reading/writing code in that language and it's usefulness from both personal as well professional point of view, the index would look like this:

As part of current project I need to test some ORM frameworks and for that, you need a database. In this particular case, database equals Oracle. I need a local instance to be able to work outside of the customer's location.

On my notebook, I have already installation of MySQL (for all the Rails stuff) and SQLServer (for ASP.NET). Plus few lightweight databases (meaning that they do not really need a server) such as sqlite3, Derby and HSQLDB). I was very hesitant to add another instance and for some time tried to do the work with MySQL - but differences in SQL and most importantly the way how the CLOBs and BLOBs are handled convinced me this is a bad idea.

Spring example Petclinic on Tomcat 6

Thu, 20 Sep 2007 23:07:37 -0400

If you try to deploy one of the Spring 2 samples included in the Spring framework source distribution - Petclinic on Tomcat 6 (6.0.14), the web application does not get loaded and fails with errror. The cause is the ClassNotFound exception for the class org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader, more precisely:

SEVERE: LifecycleException java.lang.ClassNotFoundException: org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source)

Java Web tools: Eclipse WTP, Netbeans and MyEclipse

Tue, 18 Sep 2007 23:10:51 -0400

Part of the technology upgrade in the three Java based projects is also tool update. We have started with Eclipse version 1 and gradually moved up to the currently used Eclipse 3.0. The build and deployment process was based on custom written Ant build script, which compiled, created WAR, deployed, undeployed, run the tests, created source snapshot - you name it. The Eclipse was used mostly as editor and debugger - using JPDA talking to Tomcat started in debug mode.

Good book on Spring Framework version 2

Wed, 12 Sep 2007 22:36:00 -0400

During my recent return to Javaland, I have noticed many improvements in newer releases of well established frameworks and toolkits, as well as many new ones. One such new release is version 2 of Spring framework. It is not really a hot news, because the final version of 2.0 is out for almost a year (October 2006), but it is new to me, because I spend pretty much all of last 12 months in DotNet, C# and OLAP worlds, with only brief visits to older Struts based, Spring-free Java projects.

Fresh cup of Java

Thu, 06 Sep 2007 22:28:40 -0400

Hi, all Java gurus inside and outside of Thinknostic - I have a very interesting problem. Imagine the following situation: we have three existing Java Web applications, written back in 2000/2001, based on open source libraries of that time: Struts 0.9/1.0 and JSP 1.x (no JSTL) with Tiles for Web layer, Apache Torque for ORM, early version of Quartz for job scheduling, Jasper Reports for PDF reports and Freemarker as template engine for email creation. The application has been (and still is) in production for almost 7 years and works great. Now the customer is expanding the functionality and wants add several Ajax features - in short, version 2.0 is on the table.

Limits of virtualization

Mon, 16 Jul 2007 23:14:54 -0400

It's been over 10 months since we have started to seriously use virtualization and run Windows inside virtual machine to ease installation and configuration pain. It starting first as convenient measure of isolation two different development environments (.NET 1.1 based and .NET 2.0 based) and avoid "crosspolination" in the data analytics project. At that time, my expectations what would be the limits of what you can or cannot do in virtual environment were mostly around performance, responsiveness and device support (USB especially). As it turned out, all of that actually worked much better than I have ever expected. With new versions of Parallels, the performance is very good and user experience (user means fellow developer) is barely noticeable difference against developing on host system. Assumed that you have decent dual-core system with 2 GB of RAM, of course. Using Parallels gives you the added benefit of moving the virtual environment between Windows, Mac and Linux hosts, which is very convenient.

Total Comander version 7.01 final is out

Thu, 05 Jul 2007 22:48:37 -0400

go and get it - at http://www.ghisler.com/

It got nice visual upgrades - look and feel and icons are gently nicer and more XP-ish. Plus many other new features. Upgrade is still free for registered users.

If I should pick one single most useful program I ever used on any computer system, Total Commander would be clear winner. I do not remember when exactly I purchased the license - I guess sometimes around 1994-95, when it was named Windows Commander. Since that time, I was using it pretty much every day (except few short periods I was working exclusively on Unix). I still use it every working day (as I often spend weekends on Mac platforms).

Book review: Dreaming in Code

Mon, 02 Jul 2007 19:09:46 -0400

Thanks to long weekend and more quiet time in last couple of days (Happy 140th Birthday, Canada!), I managed to read something else than Ruby-ism/Rail-ism. Among others, I finished the Dreaming in Code by Scott Rosenberg, a book promising to explain why software is hard.

It is pretty tough question to answer. The way this books tries to address it is following the story not very well known open source project named Chandler through it's beginning over period of 3 years. Chandler was - and still is - developed by the OSAF - Open Source Application's Foundation, founded (and financed) by Mitch Kapor, who was before the founder of Lotus Development Corporation and designer of the "Ur-spreadsheet" Lotus 1-2-3.

.NET on Linux faster than on Windows ? Hmm

Wed, 27 Jun 2007 22:28:29 -0400

An interesting article on JavaLobby caught my eye today: Do .NET Applications Run Better on Java?

Normally, knowing the not exactly impartial focus of the Java centric site such as JavaLobby or theserverside.com, one should be careful when reading how much Java outperforms .NET. The bias works the other way too - just look at the Theserverside.net or other .NET centric side how much is C# superior :-). With that in mind, I looked at the technical report.

Netbeans Ruby IDE - great tool getting even better !

Sun, 24 Jun 2007 23:08:11 -0400

I have spent last two days (and few evenings before) playing with Rails and using Netbeans Ruby IDE. What a great experience ! Unlike before, it is so much easier to have really good debugger that allows put breakpoints not only into the Ruby code in controllers and model - but even into the RHTML view files !

Netbeans team works hard on improving the tool. With latest build - 2434, I have noticed great addition - Rails console. The IDE had IRB window even before, but the environment did not load the Rails context and would not recognize e.g. ActiveRecord. Now with latest build, everything works like charm.

Adding image to link with CSS only

As seen in the video at http://sciencehack.com/videos/view/IDT2RMJNvSA#searchkeywords

The source code:

Very good explanation is in the video mentioned above. So far so good - unfortunately the technique, however cool it is, does seem to work in Firefox only. Or at least it does not work in the still most prevalent browser on the Net.

Here is how it renders (properly) in Firefox (tested with 1.5)

and here is how it looks in IE7:

BOTD: Railscast

Tue, 19 Jun 2007 22:06:03 -0400

Today's blog of the day is not really a blog, but a screencast. Dedicated to Ruby on Rails, the Railscast offers (as of today) 46 episodes of short, targeted practical advice on various aspects of Rails development.

Unlike some other screencasts who try to record the screen action as MPEG movie, this one is perfectly legible. In addition to the Rails enlightenment, you can also enjoy the speed and aesthetics of using TextMate - with many great Ruby editing shortcuts and beautiful OS-X typography.

Swing-ing back - to Netbeans

Mon, 11 Jun 2007 22:22:35 -0400

It has been quite some time since I used a Swing based Java application. Compared to beauty and close-to-native feeling of Eclipse based application, Swing just did not feel right - it looked differently and behaved a bit differently. For long time, my desktop was Swing-free (not counting the JDK demo). Not any more, though.

What made me to reconsider, is new release of the Netbeans v 6. In the latest milestone builds (M6 to M9), Netbeans team built amazing Ruby development environment. Compared to Ruby plugin in Eclipse, it has way more functionality, better debugging, really impressive editing support and very cool Rails extensions. The full description of new features is here.

Martin Fowler's article on Ruby and Microsoft

Sun, 03 Jun 2007 22:25:44 -0400

There has been lots of interesting news related to Microsof and Ruby recently, mostly about DLR's support of dynamic languages. One of my favorite tech authors stirred the waters once again last Friday with an article that goes beyond this and tries to paint larger picture of the uneasy relation between Ruby platform, Agile movement, OpenSource Community and Microsoft.

One quote from the article:

The attitude to open-source is a large part of this problem. When Java appeared there were yawning gaps in its portfolio, and worse some dreadful standard tools in its API (visions of Entity Beans spring to mind). Those gaps and bad ideas were fixed by the open-source community. Ant gave us a build tool, EJB was displaced by Spring and Hibernate. .NET has also got its gaps, and again the open source community has stepped up to fill them. Yet Microsoft refuses to collaborate with these efforts, even seems to go out of its way to undermine them. I was particularly sickened by Microsoft's reaction to NUnit - an excellent XUnit testing tool, elements of whose design were lauded by Anders Hejlsberg at OOPSLA. Microsoft ended not just bringing out a competitive library, but deliberately making it incompatible. That's not the kind of reaction that encourages people to invest their time in the platform.

Code in Ruby under ASP.NET: coming soon ?

Sat, 02 Jun 2007 22:33:27 -0400

The support for using dynamic languages such as Ruby or Python to code ASP.NET pages was announced for future versions of ASP.NET in the ASP.NET futures.

Unless I am mistaken, it means that we eventually will be able to write control event handlers in Python or even Ruby - which is certainly more fun than in VB.NET or even in C#, but is it really so important ?

What would be *really* cool if the whole ASP.NET become more agile and more "rail-ish". To make overall architecture more flexible - such as departure from not very flexible page-centric architecture towards MVC and routing. Maybe some version of ActiveRecord ? Or even multiple (and pluggable) template languages ? That would be really something.

BOTD (blog of the day): Frans Bouma's Blog

Mon, 28 May 2007 22:53:00 -0400

A brief look at my Google Reader subscription list made me aware that I have added to my reading list a loooot of blogs, newslist and so on. Unfortunately, they are not organized very well and should be properly placed into folders. In a process of doing that, I will put some of the interesting blogs here.

For today, it is Frans Bouma's blog - focusing on .NET and Microsoft technology platforms. From the most recent good articles, look at why API's should not be designed by scientists - discussing and comparing various ways how the database level paging is handled in various databases (MySQL, PostgreSql, DB2, Oracle, SS2005), or read Frans' comments on Entity Framework being cut from .NET 3.5 - which is sad, but IMHO fairly accurate summary of the recent development. See for yourself.

Unified ID's for legacy database

Tue, 22 May 2007 23:20:12 -0400

I found a handy T-SQL trick that helped to solve the following problem: during datawarehouse creation, we needed to consolidate multiple data sources from databases belonging to two generations of system: older one using int identity keys, the newer one, designed for replication and distributed data scenarios using GUID's as primary keys.

In the consolidated database, we needed to create single representation that would allow to store both new GUID based identities as well as old int-based keys. Direct conversion between UNIQUEIDENTIFIER type and int is not allowed. The following one liner will do the trick:

New kid on the block in race to be Flash killer

Sat, 12 May 2007 22:27:42 -0400

After Adobe's Apollo and Microsoft's Silverlight, Sun has addes own version of scriptable, interactive platform named JavaFX. Unlike the previous three (Flash included), this is going to be Open Sourced - under the Microsoft's most hated license - GPL.

Now the race to replace Flash really becomes really interesting ...

Differences between Visual Studio and SSMS

Fri, 11 May 2007 22:43:32 -0400

I am working on the BI modules for automotive data-analytics application these days. Which means that I am doing quite a bit coding and using T-SQL and in addition to Visual Studio 2005, I use quite often the Sql Server Management Studio for SQL Server 2005. In theory, both tools should be based on the Visual Studio IDE code base. Which is maybe true, but there are many quite annoying differences.

Rails' ideas everywhere

Wed, 09 May 2007 22:22:10 -0400

Since I got through "Rails immersion", I keep seeing the implementations of the same idea everywhere. Latest find is Subsonic, which implements Active Records in .NET space. Rather than writing more, see this screencast.

It's all about numbers

Sat, 05 May 2007 22:39:38 -0400

Imagine if somebody got copyright on a number 32. You could not say any more on a Web page that you use 32 bit OS because you were not allowed to use the number. You could not even write thirty two, or 0x20... Could not send a card for 32nd birthday. Sounds crazy, right ?

But exactly this is happening. Somebody is trying to claim exclusive ownership of one number and sending take-down letters, law threats to those you have it posted on their web sites or blogs.

Fixing broken ASP.NET development environment

Thu, 03 May 2007 22:18:19 -0400

I had again the not-so infrequent pleasure of setting up fresh copy of Windows development stack. We were moving few machines between projects and to make sure that no forgotten source files are left on the harddisk, we reformatted and reinstalled Windows from scratch. It is usually good idea anyway, because developers like to install strange tools and utilities and generally customize machines to their own taste, which tend to be unique and is seldom shared.

Microsoft is getting more dynamic

Tue, 01 May 2007 22:08:12 -0400

at least as the programming language languages are concerned. One of the things that will be presented on the MIX07 is Dynamic Language Runtime, a new platform suitable to host high level, dynamic languages such as Python and Ruby. For Python, there is already pretty decent .NET implementation - namely IronPython. What is coming now is IronPython 2.0 based on the DLR as well as - yesss - IronRuby.

It is great that this is happening. In Java world, JRuby is very close to being full implementation of the language. The speed of the JRuby is still not quite in the proximity of the C implementation, but the large selling point of JRuby is its capability of deploying Ruby application (or even a Rails application) inside Tomcat or any other Java Web container. This removes largest obstacle of using Ruby in enterprise environment - namely being "new" and not approved platform. When the .NET runtime will be able to host Ruby code, acceptance in enterprise space will be even higher.

Accessing SQL Server 2005 from Ruby

Wed, 25 Apr 2007 23:58:13 -0400

The natural gravity of our environment keeps pulling me out of scripting and Ruby world back to .Net zone :-). Out of curiosity, I looked into how easy or hard is it to access other database from Ruby, than the default MySQL which dominates all books, samples and tutorials.

I have found three ways (at least), one likely platform independent and two Windows only. The platform independent requires module ADO.rb and works with the DBI interface. This sounds very similar to the way how Perl used to access databases, so I put this at the end of the list (some details are here). First Windows only methods used ODBC - no, thanks. Configuring machine specific data sources is not the way I wanted.

In praise of the polyglot

Tue, 24 Apr 2007 23:55:34 -0400

If you've ever envied the ability of multilingual friends to bridge language gaps wherever they travel or gained new appreciation for your native language by learning a new one, then you can probably see the advantage of being a programming language polyglot. Developer polyglots travel the IT world more freely than do monolinguists (sure that they can apply their skills in any environment), and they also tend to better appreciate the programming language called home, because among other things they know the roots from which that home is sprung. Isn't it time you became a polyglot?

One more reason to like TWIT

Mon, 23 Apr 2007 22:42:58 -0400

As it happens, both my most favorite podcasters - Leo Laporte as well as Steve Gibson are passionate e-book readers. They have both purchased and are (mostly) happy users of the Sony PRS-500 aka Sony Reader in addition to several other platforms - (Palm, Pocket PC). In the latest podcasts - both in TWIT as well as Security Now!, the eBooks and eReader got quite some publicity :-).

Both had similar experience with PDF format on PRS-500 as myself - but Steve mentioned the PDF re-flowing the document to make it better suites for small screen - something I have looked into but did not get it working quite right. The preferred approach to using Reader is RTF format - which again, matches my impressions.

Four quadrants of uncertainty

Sat, 21 Apr 2007 22:54:58 -0400

(a followup to discussion last week)

In every outsourced software project you have four large areas: your customer, the business vertical you are writing software for, your implementation team and the technology foundation or platform you are using.

Two of these areas are on "internal" side of your organization (team and technology), two of them are on external - your customer side (business domain and customer organization). Two are more micro level in the sense that they have strong human interaction aspect (customer and team) and two are more macrolevel and less personal (business domain and technology). For that reason, you can represent these areas as quadrants using two axis micro/macro and internal/external: micro+internal = team, micro+external = customer, macro+internal = platform, macro+external = business domain.The degree of risk in the project is proportional to how many of these quadrants are actually unknown or new. Why is that ?

Unify Tour 2007 and Open Source

Thu, 19 Apr 2007 23:44:16 -0400

This week was full with attending the demos and workshops. On Tuesday, I spent half day on the Microsoft Unify Tour 2007. I planned to be there full day but an important business meeting made me change the plan. Fortunately, the sessions should be available recorded on the Web, so I will be able to check them later. The topic was bang-on - considering that we are in final phase of large project, using distributed network of SQL Server 2005 installations with replication and location was same as usual.

Gems and bookmarks

Mon, 09 Apr 2007 22:36:06 -0400

This was one great weekend ! Easter should be more often than once a year, I guess. Unlike Christmas, there was no shopping craziness before and much less overeating danger. Not counting overdose of chocolate, of course, but that's OK.

I managed do mostly nothing for about one day - up to Friday evening. Then I dived into the Ruby and Ruby on Rails world. After reading this and one third of this book, I like Ruby even more. I actually did write some code - not much, but rewrote some of my old Python scripts I use to manage files and repositories. The new Ruby version is shorter and IMHO more elegant (even with my limited command of Ruby idioms), much better readable - albeit a bit slower than Python version. But that does not change my very positive impression of new language. In addition to these (and btw, the mixin's are so great it is even scary), I learned to love the Rake and gem tools. Gem is pre-packaged Ruby component, managed as unit, that can be installed and updated remotely using the gem tool. It solves the problem of versioning - something I wished Java had from the beginning. It also provide similar functionality as the GAC in .NET: allows side-by-side existence of multiple versions of the same component and makes component available to other programs. Very clever, very convenient. Same story as with the language - gem is something similar that Perl did have with CPAN, but it is just cleaner, nicer and polished ...

Very useful data structure and algorithms library

Mon, 02 Apr 2007 22:28:52 -0400

.NET 2.0 offers very rich and nicely designed library of core data structures, collections and algorithms. Occasionaly, you run into situation when you need something not in there. Before starting to design you very own extension of LinkedList or HashTable, look into interesting open-source project NGenerics - chances are you will find it there.

It contains quite a few new data structures:

extensions of existing data structures to work with Visitor pattern

Couple of things I really like about Ruby

Sun, 01 Apr 2007 22:45:29 -0400

I guess it is too early to write any more systematic opinion about the language you know less than 10 days, but after reading the Programming Ruby 2nd edition (thank you, Safari Books) I have found out that I actually do like couple of Ruby features a lot. Your mileage may vary - what speaks here is my Java/C#/C++/C/Python/Perl background and bias. Here there are my favorite Ruby-isms (so far) in no particular order:

Walking season ... and SPAM

Sat, 31 Mar 2007 22:10:53 -0400

Today I have started the walking season 2007. I did some gentle preparation during the week - few short, 4-5 km strolls around the neighbourhood, but it was today when I really started. It was beautiful day in Ottawa - sunny, temperature around 8-10, so I took off and did 12 km loop through Westboro, down south and around Dow's Lake up to downtown. Just fantastic. The companion on the road were Security Now! - I was behind few episodes, but I managed to listen to almost full 3 episodes.

How to access GMail with multiple POP clients

Fri, 30 Mar 2007 20:39:35 -0400

Man lernt nie aus - as the German say - one never stops learning. Thanks to comment found on my blog I found out that there is very nice solution problem of disappearing emails (after you download it with one POP client, other POP client would not get it). It is even documented in GMail help:

http://mail.google.com/support/bin/answer.py?answer=47948&topic=1556If you're accessing your Gmail using POP from multiple clients, Gmail's recent mode makes sure that all messages are made available to each client, rather than only to the first client to access new mail.

Upgrading Java and Open Source libraries

Wed, 28 Mar 2007 21:28:22 -0400

As Murphy said - you cannot do just one thing. Thanks to JDK 1.4 entering end-of-life support period (and 1.3 being unsupported for some time), we need to move few applications happily running on these antique Java platforms to at least Java 5 and gain few more years of uninterrupted Sun-supported life.

Upgrading the applications was as expected, piece of cake - as long as you have solid build environment with build scripts and everything - which we certainly do. Ant runs on Java5 exactly as well as on 1.4 (maybe faster, but I did not measure), Tomcat was the same no-brainer thing and switching the Eclipse required only selecting different JRE in preferences window. Codewise, the only change required inside the application code was renaming few identifiers to something else than enum, which happens to be keyword in Java 5.

Ode on Eclipse :-)

Tue, 27 Mar 2007 20:52:31 -0400

After almost two years of uninterrupted C# and .NET development, I have got back for few days to Java world. One of our old customers asked us to do few enhancements and changes in the application we wrote. And because we always stand behind our work, always do answer the call for help and do support our customers as long as they want to be supported, I have squeezed-in few days worth of work into pretty packed schedule. So here am I on a short detour into world of class files and jars ...

Managing knowledge portfolio

Sun, 25 Mar 2007 22:50:43 -0400

There are few technical books which you enjoy first time you read them, remember the experience and keep coming back. One of such classic books is The Pragmatic Programmer - from journeyman to master - by David Thomas and Andrew Hunt. If you have not read it, get it, it is worth every cent. Since the book was written - ages ago, back in 2000 - it did not loose anything of its freshness and value - which one cannot say about most of technical books written earlier than 2-3 years ago. Inspired by the success of their initial creation, Dave and Andrew started the website and continued writing whole Pragmatic Programmer series of books.

Converting eBooks to Sony Reader format

Thu, 22 Mar 2007 19:50:51 -0400

Since yesterday, I made nice progress in solving my issues with content creation for PRS500 and it's readability. There are several ways how to proceed:

The simplest is to download Book Designer. It is free for non-commercial use and current version 5.0 Alpha does the job very well. It allows you to load source in text, HTML, Lit, PDF, PalmDoc (prd/prc), rb and few other formats and process them into native LRF format - plus few others I do not really care about. The result is nice, readable LRF file with three sizes, nicely formatted, with metada. As added benefit, because the author is Russian, the program does not assume that English alphabet is the only one in existence and allows to select encoding. The result is quite good - most of the extended characters from Czech/Slovak are there, some are missing and displayed as space (namely ř,ě,ľ ...) but it is readable. What is maybe better option is that with English as language and default encoding, the software "downscales" the extended characters to closest English pairs: ř -> r,ě -> e - which results in familiar computer Czech/Slovak. I am very comfortable with option 2, and will work on getting correct font for #1.

Epigrams on Programming

Wed, 07 Mar 2007 21:03:40 -0500

My favorite top ten epigrams, for more see http://www.cs.yale.edu/quotes.html

0. One man's constant is another man's variable

1. It is easier to write an incorrect program than understand a correct one.

2. If you have a procedure with ten parameters, you probably missed some.

3. A language that doesn't affect the way you think about programming, is not worth knowing.

4. Simplicity does not precede complexity, but follows it.

5. You can't communicate complexity, only an awareness of it.

Introduction to CSLA - lunch presentation at ODNC

Wed, 28 Feb 2007 22:21:31 -0500

The Ottawa .NET Community organized today interesting lunch-and-learn session: first of two sessions on introducing the Rocky Lhotka's CSLA Framework. Usual location - Glacier Room at downtown Microsoft Office. I decided to attend for two reasons: first was that I knew the presenter - David Campbell. David is a great guy - consultant with 20 years of history in the software development business, running his own company. Last year when we were looking for people with CSLA experience in Ottawa, David's name came out first.

Scripting, repeatability and GUI

Mon, 26 Feb 2007 22:15:53 -0500

Most programmers love GUI. It is so easy, so convenient, just point and click here, click there, drag and drop, repeat few times and problem solved. Who in sanemind would bother typing and writing code when can GUI do it all. The convenience rules. If you need to add or change something, it takes just few more clicks. Not a big deal, just add a few more easy steps. No problem - right ? Wrong !

More great programming quotes

Sat, 24 Feb 2007 20:13:09 -0500

It has been said that the great scientific disciplines are examples of giants standing on the shoulders of other giants. It has also been said that the software industry is an example of midgets standing on the toes of other midgets. [Alan Cooper]

And the users exclaimed with a laugh and a taunt: "It's just what we asked for but not what we want."

For a sucessful technology, honesty must take precedence over public relations for nature cannot be fooled. [Richard Feynman]

Quote of the day

Thu, 22 Feb 2007 23:50:38 -0500

We build software line by line, idea by idea, side by side. Our software is an expression of ourselves, our best moments, our toughest challenges, our greatest hopes.

This wonderful quote is from handcrafted copy of Vista, which was distributed to everybody who worked on a product. It is a Microsoft tradition that the people who worked on a project get a copy of the project when it ships.

Hiring programmers - or Degrees of Done

Wed, 21 Feb 2007 23:57:37 -0500

Back in old country, I once had a programmer working for me who made himself famous with the following quote:

"I have fixed that bug, do you want me to compile it too ?".

In his mind, he was done as soon as he identified the bug and put the fix in the code. All the rest was trivial and unimportant routine.

During last 20 years I have worked with many very different developers and learned the hard way, how very many different meanings the word "done" can have. For some, done means that coding just finished and he/she successfully compiled the projects and stepped through some of the code paths with debugger with negligible occurrences of major crash. Whether the code is in CVS, commented - who cares ?

DotNet Development Toolbox - II

Tue, 20 Feb 2007 21:51:00 -0500

Continuing from here.

Ch-7: Digging into the source code

In this chapter, Mike describes the tools that work with, around or towards source code: Idlasm, Reflector and FxCop. The book is written for Visual Studio 2003, so some references are slightly outdated - but there is one utility that stands out and is still more useful than ever: Lutz Roeder's Reflector. It is part of the Visual Studio 2005 (albeit in older version that you can get on the Web site).

Handling concurrency in SQL Server applications

Wed, 14 Feb 2007 22:24:49 -0500

On Tuesday evening, the Ottawa Dotnet Users Group organized presentation of Adam Machanic from Boston with title "Designing Highly Concurrent SQL Server Database Applications". I was not sure whether I will make it, because because I did not feel really well, but I am very happy I went.

It was probably one of the best presentations I have seen in Microsoft Glacier Room on 100 Queen Street. I am not sure whether because it was indeed so great or because it touches closely what we are doing.

Software Oscar Award

In software industry there are no annual awards and recognitions of achievements that would resemble the Annual Academy Awards of the movie industry. Various magazines, publishers and companies do present theirs yearly list of Best Products, but they are often biased and seldom representative. The one list that stands apart and that in my opinion comes closest the Oscar is Jolt Awards published by used-to-be one of the best magazines for professional programmers - Dr Dobbs Journal. It is still around and still a pretty good magazine, I guess - but the evolution of the Internet and shift of the money towards on-line advertisement changed the business landscape for most of the magazines, depending on revenue stream from ads. The list has various categories: for books (general and technical), project management, database systems and tools, IDE, design tools, development libraries and so on.

Webbits - 2007-01

Tue, 23 Jan 2007 19:38:26 -0500

Webbit is like timbit - it comes in 12, 20 or 40 pack, contains many small pieces of different taste and color, is generally unhealthy but good, can be addictive and is nice addition to your morning "extra large, double cream" from Tim Hortons. Unlike from timbits, from webbits you will not get fat, only distracted. Enjoy !

The Quizstop allows you to select how fast are you reflexes with the mouse. Something for those with competitive gene among us (I mean you Igor, of course ;-).

FEOTD: Clippings - GMail's best friend

Mon, 22 Jan 2007 19:43:51 -0500

Thanks to Lifehacker I have discovered this extension which add missing piece of GMail functionality:

This very simple extension allows you to enter multiple sets of text (such as e-mail signatures) and paste them into forms simply by right-clicking.

Why is this such a big deal ? I am using GMail for both my personal and work stuff. To make sure my work related email appear as coming from company email address, I set the proper From address when composing an email. GMail can be configured to stay with the recipient address when replying. The only problem is signature. In private emails, I want to have link to the blog, in work emails, to company site. And GMail offers only one signature. With this extension, I do not use any signature from GMail, just simply insert correct one from the Clippings buffer.

FEOTD: well hidden secret

Today's extension is one that most people do not know about - and still almost everybody has it installed. The explanation for both is that it is distributed with Firefox, and unless you specifically prevent it's installation, you will get it. It is DOM Inspector.

Why would you care about something like this ? Unless you make living by creating Web applications, you probably would not. But if you do, it can help you a lot !

Vista security and Java

Tue, 26 Dec 2006 20:44:11 -0500

I had a brief MSN chat with friend of mine today, who tried to install and use Vista as development platform. I mean install on the real hardware, in order to use it as core operating system. I have no feedback yet on how Visual Studio works, but as he found out, his Ant build files he uses to compile and deploy Java programs stopped working - because Vista did not allow to copy Javascript files. I can understand why Javascript files are treated with caution - however, it should not be considered the same when a file is copied from a local file to a local file, rather then downloaded from the internet.

Few new links from my del.icio.us collection

According Forrester reseach ".. the Web will fade. It will be replaced by a new software paradigm". Nobody knows what this new paradigm will be, but these guys are saying that it will be their platform. I found this link from this very interesting two part article Changing Climates for Microsoft and Google, Desktops and Webs making interesting analogy between Google and AOL business model, browser as a platform and possible return of thick client ("smart client" in Microsoft terms), why Google might want to buy Adobe and many other interesting observations. Worth reading.

I have switched away from using Outlook once again for variety of reasons - as part of my latest attempts to reduce complexity and increase security (more on that later) and went back to Thunderbird/Web based email systems on all Windows machines. Conversion of address books was piece of cake this time, thanks to Plaxo which I use to synchronize Mac and Windows based systems. Nonetheless, I got curious what format does Thunderbird use for address book and this way I have discovered the awkward Mork file format.

Will C# 3.0 become an uglier version of Python ?

Mon, 04 Dec 2006 22:54:43 -0500

It is now about 1 year since official release of C# 2.0 and .NET framework 2.0. The next version of C# language - the C# 3.0 seems to get more and more attention - in blogs, official channels and MSDN. There is lot of excitement and big expectations - but I have nagging feeling that the general direction of the C# development is not necessary an improvement.

The main new features of the C# 3.0 language are implicitly typed variables and anonymous types, extension methods, lambda expressions, and LINQ - possibility of using SQL-ish dialect inside the C#. With exception of the last, all of them must sound very familiar to every Python programmer. All variables in Python are implicitly typed, we can extend classes to much larger degree than extension methods and lambda expressions were always integral part of Python (inherited from Lisp and Scheme).
