Linode is Blazzing Fast

Personal, Thoughts
I asked my client to buy a Linode for some testing purposes and I tried it for the first time. I must say, Linode is blazzing fast. Downloads are touching 8M/sec and speed, performance is as if its running on a VM on my local system. Update: Now its been almost a month running Linode and I strongly recommend this VPS company.

Good bye CentOS! Hello Ubuntu

CentOS, Linux, PHP, Reviews, Tips and Tricks, Ubuntu
Its been about almost more then two years since I have been playing with CentOS on many different platforms etc. Its very stable but on the other hand, PHP/MySQL updates are very hard to get and still PHP is 5.1.6. I tried EPEL repo and it updated PHP to 5.3.1 but still there were conflicts with stuff and many core packages. So, I thought why not move to Ubuntu since it has just announced 10.04LTS (Long Term Support) in April 2010. Folks at iWeb were really nice to do a reinstall without any charges and also process a memory upgrade request at an amazing 50% discount. Ubuntu 10.04 LTS Apache 2 version is 2.2.14 PHP version is 5.3.2 MySQL version is 5.1.41-3ubuntu12 SVN (Subversion) version is 1.6.6 As a comparison…

To update or not to update?

CentOS, Linux, Thoughts, Ubuntu
All my technical life, I knew and followed this simple rule New updates to any application or component are meant to improve and fix the bugs present in it. Downloading new updates ensures that you system is up-to-update, has fixes to all those bugs you have been getting annoyed with and more stable. Unfortunately not every IT department thinks that, especially the one I am facing at work. According to them, the new updates should only be applied IF and only IF they offer some new functionality (duhh!). Hello! what happened to the bug-fixes that are promised with these updates? (more…)

How to Install Apache, PHP and MySQL on CentOS

How to, Linux, OpenSource, PHP, Resources, Tips and Tricks, Tutorials
I have seen people installing Apache, PHP and MySQL from source code on a production server. You should NEVER, NEVER, NEVER install these packages from source on an RPM or DEB based Linux distributions. Did I say “NEVER” enough times to make your realize that it is not a good practice? Installing from source is bad idea; there are many reasons for this but the major one is that you will be spending a lot of time keeping the system updated. If you love installing from source then I would suggest using a different distribution e.g. Gentoo. You can build from source if the package is not available in yum but still, try to use “yum” (or “apt-get” on Ubuntu) because it will save a lot of your time when…
