OpenVZ Inside VirtualBox on iMac

OpenVZ Inside VirtualBox on iMac

Posted by SibProgrammer on March 12, 2011|Comments

I finally decided to install VirtualBox on Mac. The main reason is a testing of new releases of OpenVZ Web Panel. I have several physical servers under OpenVZ, but I can’t extensively test Owp on them. Because have a lot of virtual servers there that could be damaged due to some bug in panel during testing process.

Neither VMware Fusion nor Parallels Desktop is not really interesting for me. They primary focused on Windows virtualization and both are commercial solutions. Hearing for a long time about how cool VirtualBox is, I finally decided to try it.

After setup I downloaded Debian 6 netinstall iso and installed the system. As my goal was to test Owp, next step was to install OpenVZ kernel. It failed for the first time. But after enabling PAE/NX for virtual machine, the second attempt was succeeded.

Next question was the performance. I really impressed! Virtual server on iMac works really fast, even faster than one of my physical servers.

So next Owp release will be also tested with assistance of VirtualBox and snapshots. I’m really glad that I switched from my old VMware server, which I used from time to time for testing purposes and it was very slow.

Parallels Plesk Panel 10 Release

Parallels Plesk Panel 10 Release

Posted by SibProgrammer on November 03, 2010|Comments

Parallels Plesk Panel 10 was officially announced last night. As one of the members of dev team, I’m very glad to see that product is available for customers.

There are so many things were changed, especially in business model. So I think, that it’s better to install new version on new server, instead of upgrading of existing installations. But all these changes are focused on customers needs satisfaction. And Parallels internal expectations on Panel 10 are very high.

Panel 10 comes with brand new Sitebuilder out of the box. Try to spend some time to find it, and you should be impressed :)

One more interesting thing is that Panel 10 has “Power User mode”. You can switch the Panel 10 to this mode and you’ll get the product, which is… very similar to Parallels Small Business Panel. Really it should be a replacement for older product. This mode is designed for small and medium companies (SMBs) to organize their business on web. All shared hosting related stuff such as plans, resellers and etc will be hidden. But the panel is still powerful.

Simplify bashrc Edits

Posted by SibProgrammer on October 07, 2010|Comments

Recently I found interesting alias, which can simplify .bashrc edits. The alias is here:

alias bashrc='vi ~/.bashrc && source ~/.bashrc'

You’ll get bashrc command and it’ll be applied automatically after editing the file. Simple and cool :)

Bash with Colors

Bash with Colors

Posted by SibProgrammer on October 06, 2010|Comments

I like to use colors in my *nix terminals. Information visualization speeds up the development. At least I think so :)

Typically I add the following aliases to ~/.bashrc:

alias ll='ls -la --color'
alias less='less -Ri'
alias grep='grep --color=always'
alias ack-grep='ack-grep -a --color'

These aliases allow to perform commands like ack-grep User | less and see colorful output.

Additional tweaks needed for subversion and git. To see diff with colors need to install colordiff first. Then need to add to ~/.subversion/config (inside helpers section):

diff-cmd = colordiff

To make git commands output colorful the magic command can help:

git config --global color.ui always

Unique Objects Identifiers in PHP

Posted by SibProgrammer on October 06, 2010|Comments

Today during optimization session of one application, I found spl_object_hash function very useful. It returns unique identifier for given object, thus giving the ability to identify the same objects across application.

irb Commands History

Posted by SibProgrammer on August 07, 2010|Comments

Playing often with irb and script/console I always setup irb command history on the machine. It can be done by adding to ~/.irbrc the following code:

require "irb/completion"
require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 1000
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb_history"
