Fri, 04 Apr 2014 11:22:48 +0800

How to install Chrome in Centos 6.5
#

Step 1. Add Google Yum Repository
#

Create a new yum repository using below instructions.

sudo vim /etc/yum.repos.d/google.repo

Add following content to this file

[google]
name=Google
baseurl=http://dl.google.com/linux/rpm/stable/$basearch
enabled=1
gpgcheck=1
gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

Step 2: Install/Update Google Chrome
#

Richard Lloid provided an shell script to grab libraries from a more recent Linux distro, put them in a tree (/opt/google/chrome/lib) exclusively picked up by Google Chrome and then you can indeed run Google Chrome on CentOS 6.4 or later. Read More

Installation of sshfs in the new VM

Tue, 11 Mar 2014 11:22:48 +0800

Installation of sshfs in the new VM
#

On Centos 6, the fuse-sshfs is not part of default YUM repos.

Get the ’epel’ repos
#

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

Validate

$ ls -1 /etc/yum.repos.d/epel* /etc/yum.repos.d/remi.repo
/etc/yum.repos.d/epel.repo
/etc/yum.repos.d/epel-testing.repo
/etc/yum.repos.d/remi.repo

It if good idea to enable the remi by default

Thu, 03 Feb 2011 11:22:48 +0800

1) make sure the DNS works
#

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

nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 192.168.16.1

2) check that you have ntpd installed
#

cat /etc/ntp.conf

3) make it work in all
#

/sbin/chkconfig --list | grep ntpd
sudo /sbin/chkconfig --level 2345 ntpd on

4) Initial sync
#

sudo /usr/sbin/ntpdate pool.ntp.org

Linux vs Windows - great comparison

Fri, 22 Aug 2008 23:35:47 -0400

I have been "living in a command line" for last few weeks. Pretty refreshing experience. As result, I had to google a lot, especially when it comes to e.g. subtle differences between tar options on Ubuntu Linux and Open Solaris ... While doing that, I somehow stumbled upon this great writeup on cultural differences between Linux and Windows. Nicely written, no flamewars - obviously pro-Linux, but no Microsoft or Windows bashing and lots of insight. Higly recommended.

.NET on Linux faster than on Windows ? Hmm

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.
