PHP – Doctrine – DQL – Select Subquery

Mike Purcell — Fri, 07 Jun 2013 17:37:09 +0000

Whilst working on a recent project I needed the ability to do a subquery look-up as part of a select statement. Basically I needed to count the number of rows, without having to do a group by on the entire result set. After a few minutes of research I noticed there was no real definitive source on [...]

iTerm2 – Reattach a Detached Window as a Tab to Another Window

Mike Purcell — Mon, 29 Apr 2013 23:15:23 +0000

I love iTerm2, much more than the default terminal that is shipped with the Mac OS, but I could never figure out how to reattach a detached window as tab to another window. After some futzing around, I finally figured it out. Go to iTerm - Preferences - Appearance. Next de-select the “Hide tab bar [...]

Javascript – jQuery – Stopping Event Propagation – stopImmediatePropagation

Mike Purcell — Fri, 05 Apr 2013 17:19:06 +0000

Recently ran into another issue where I had two separate and de-coupled event handlers tied to the same dom element, specifically a form submit. However, the first event handler returned false if certain checkboxes were not checked (business rules), but the false was ignored by the second event [...]

Javascript – JQuery – Google Analytics – Submit Form Using GET Instead of POST

Mike Purcell — Thu, 28 Mar 2013 00:17:54 +0000

Was working on adding Google Analytics cross domain tracking for a form which uses the GET (instead of POST) method. The problem I was running into was the Google Analytics Tracking Cookie (GATC) data was not being added to the url, because the form’s data was overriding Google’s data. And I [...]

Symfony – Share Template Across Multiple Apps

Mike Purcell — Wed, 27 Feb 2013 00:05:27 +0000

I am currently working on a new project where I wanted multiple apps (frontend (fe) and backend (be)) to have the same exact appearance, and without having to duplicate the code in both template/layout.php files. So what I did is chose the fe layout.php file as the master template, then made the [...]

Mike Purcell — Thu, 24 Jan 2013 21:27:40 +0000

After moving melikedev.com to a vps, I was able to improve performance by configuring nginx to serve static assets while apache serves the content. In order to test if the NGinx config was correctly configured I used the ‘curl’ command to test response headers of known static assets. After testing [...]

Puppet – Wrong Header Line Format – Error

Mike Purcell — Thu, 24 Jan 2013 01:13:12 +0000

If you are writing manifests which include using templates and you receive a wrong header line format error message, it means there is a syntax error in one of your template files. The message is pretty much worthless due to it’s cryptic nature, and there appears to be an open defect to improve the [...]

PHP – ZipArchive – 5.3.x – Weird Issue when Unlinking a File Just Added to Archive

Mike Purcell — Wed, 23 Jan 2013 23:33:16 +0000

At work, I was tasked with porting some cronjobs from an old server (php 5.2.x) to a new server (php 5.3.x) and ran into a weird issue. The code to be ported was explicitly unlinking a file which was just added to the ZipArchive, in efforts to keep the filesystem clean, and ran fine on php 5.2.x, [...]
