I’ve implemented a number of sites with Elastic Search and recently had a two-day spike to implement Elastic Search for Photobox’s backoffice systems. As a result I have since wrote a presentation and presented at Photobox on Friday. I have posted the slides for the presentation here… I wrote this presentation using – reveal.js, […]

At Everlution we did a hack day to help motivate developers and to get the team working together. We started at 8.30am and finished at 5pm. It was pretty impressive what all the teams managed to achieve, with four teams of two developers and a designer. It was set out in a competition style event […]

I previously wrote about “Installing Java & MySQL – unattended/non-interactive installation”. Whilst using slack, I have been running apt-get during postinstall rather than preinstall. Files are transferred from slack after preinstall as such transferring any files that conflict with the packages configuration files, apt-get will prompt regardless of DEBIAN_FRONTEND=noninteractive. Not ideal if your trying to […]

A nice tip for logging data against apache logs within requests. Apache_note is a wrapper for Apache’s table_get and table_set. It edits the table of notes that exists during a request. The table’s purpose is to allow Apache modules to communicate. if (function_exists(‘apache_note’)) { if (isset($_SESSION) && !empty($_SESSION)) { apache_note(‘session_id’, session_id()); apache_note(‘users_id’, isset($_SESSION[‘users_id’])? $_SESSION[‘users_id’] : […]

Vagrant is simply a wrapper around Virtualbox headless that allows for provisioning virtual machines with support for puppet, chef-solo, chef, and bash. This allows you to automate the deployment and sandboxing of development sites. Additional base box images can be found at Installing Vagrant apt-get install -y ruby1.9.1 ruby1.9.1-dev ln -svf /usr/bin/ruby1.9.1 /etc/alternatives/ruby gem […]

Every now and then I come across a problem with PHPs autoloading whereby class_exists fails to autoload classes. I’ve noticed this with a number of PHP versions, most recently with 5.3.2-1ubuntu4.9. Typically I’ve resolved this by simply upgrading the PHP version. In the following example the initial class_exists fails until you instantiate the object and […]

I Spent a little while yesterday investigating why memcached causes problems with multigets returning results and ended up comparing debian vs ubuntu. I tested from virtual machines and physical hardware of relative specs. I have also tried a combination of libmemcached libraries and tuned the tcp stack, however here are some of the results from […]

One of our clients Gorkana was bought by Durrants. As such I have been working on integrating and merging data. As a result I wrote a script to synchronize data between MySQL and Oracle, which is presently a one way synchronization. The implementation The script(s) to synchronize data was broken into a few scripts. Automatically […]

A while back a colleague and myself had a two week sprint to ensure that we could deliver 20k emails with up to 5mb attachments each. We experimented with 4k emails at 5mb each sending straight through the MTA, which we found to cause excessive load on the servers. Using exim filters we could add […]

The Project I was recently working on a project to expose our trading systems via XmlRpc, Rest and SOAP. It was quite an interesting project, which took two of us three weeks to develop (Amongst other things). This involved creating a testbed, that would automatically generate the payload and response for each protocol. The parameters […]
