• jQuery Using and Manipulating Select Lists August 10, 2009

  JQuery is a fantastic tool but sometimes its functionality can be obscure or doing it one way might not work in a certain browser (MSIE6 anybody!). I have often found myself trying to remember the best way to work with HTML select lists so I am compiling this list of hints for future use and I hope that you find it useful. All the examples below are written where this represents the select element of the select list. Read more ⇒

• Moving to git and setting up InDefero as a web frontend August 4, 2009

  Most of our development is done on Vista desktops (although I also run Ubuntu of course) and we wanted a web interface for easy browsing of code so I needed to use a pervasive and well supported VCS. After much hunting around and looking at Bazaar, Mercurial and git I decided to go with the latter due to its support in the community. There are still some reservations I have against git, which work well for Linux kernal development but not our day to day web development – the major one being that subversion would allow you to commit and update on a file by file basis where as git versions the entire repository at once as far as I am aware.

• Handy Linux Commands May 12, 2009

  I use most of these commands every day to simplify my terminal interactions with an Ubuntu development box. This is more of a personal reference but thought I would share incase you find it useful. Task Command Get all users on the system for user in `getent passwd | cut -d: -f1`; do id $user; done Delete all .svn or any file name by replacing .svn in the command with your filename Read more ⇒

• Samba File Share Over SSH Tunnel April 30, 2009

  This is not a post about setting up Samba shares. If that is what you are looking for then I can recommend the following book; Using Samba: A File & Print Server for Linux, Unix & Mac OS X. Sometimes you need to be able to access a remote Samba server in a secure manner from a Windows machine. This is a relatively simple procedure on an XP SP3 machine like mine linking into an Ubuntu server pre setup with Samba file sharing.

• Memcached and APC: Two Simple Techniques to Speed up your PHP Webpages April 23, 2009

  Memcached and APC are two tools that you can install on your server and gain almost instant gratification! APC basically caches executions that you send to a PHP process so that the next time you ask the parser to run your script it only has to look for some pre-chewed opcode in memory rather than parsing your PHP from the disk. APC also has another feature up its sleeve, memory object caching, which allows you to store objects such as results from a database table in memory.

• Installing APC and Memcached for PHP Sessions on Ubuntu and Debi… April 10, 2009

  Installing APC on Debian or Ubuntu is as simple as: **user@server:/directory/$** sudo apt-get install php-apc Now let us reboot the Apache process to enable our new cache: **user@server:/directory/$** sudo /etc/init.d/apache2 restart APC should now be ready to run on your server. Try running the following command to verify it is setup; you should get something in response like mine: **user@server:/directory/$** php -r ‘phpinfo();’ | grep ‘apc’ apc MMAP File Mask => /tmp/apc.

• Haiku OS Progress April 2, 2009

  I have previously written about Haiku (formerly OpenBeOs) on my blog and I am pleased to say that I revisited this project last night and had a play with the latest nightly builds. It has moved on from the last time I look at it nearly 4 years ago now, but it still has some way to go before it will be a plug and play replacement for the old BeOS 5.

• Using phing for good - Unfuddle Add Repository and SVN Import Ta… March 24, 2009

  As you may be aware I have recently been playing with the excellent Agavi framework and it introduced me to the interesting phing tool. Phing can be used to automate tasks with build files that are close to interoperable with Apache Ant, which uses XML files to configure builds. The advantage phing has for us PHP users is that it is entirely written in PHP so extending it is as simple as adding a new class.

• Installing APC and Memcached for PHP Sessions on Redhat March 23, 2009

  Installing APC on Redhat is as simple as: [user@server directory]# yum install php-pecl-apc APC should now be ready to run on your server. Try running the following command to verify it is setup; you should get something in response like mine: [user@server directory]# php -r ‘phpinfo();’ | grep ‘apc’ apc MMAP File Mask => /tmp/apc.s5jA6w apc.cache_by_default => On => On apc.coredump_unmap => Off => Off apc.enable_cli => On => On apc.

• PuTTY and Control + S or Ctrl + S March 16, 2009

  As you have found this page I am sure you have accidentally hit the control+s short cut whilst inside a PuTTY shell and following that no keystrokes appear to affect the session. Basically hitting ctrl+s causes PuTTY to stop executing the stream coming in from the keyboard. It does however still listen to your keystrokes and it basically adds them to a queue. Hitting control+q will re-open the stream execution, but it is worthwhile noting that it will also execute all the queued up commands as well! Read more ⇒
