  1. What Does URI Stand For?


    I get a lot of complaints about an API that I maintain (http://api.joind.in) which is "missing" the ID field. This ID field is the database's primary key; if the user doesn't have access to the database (they don't), then it seems to me that the primary key …

  2. Getting Started with Beanstalkd


    I had a good experience implementing beanstalkd for the first time last week, so I thought I'd write down how that went and what I learned.

  3. PHP and Git Training Course Dates


    I've had a little flurry of enquiries about training lately, so I thought I'd mention the courses I have coming up, as especially the PHP ones are topics that I don't run public classes on all that often. At the time of writing I have some space on all of these classes:

  4. Use a GitHub Branch as a Composer Dependency


    My current project sees Celery (a python distributed task queue) added to my PHP application. There's a handy PHP interface to the RabbitMQ that Celery uses as a backend, which makes it easy for me to create jobs, called celery-php. This requires either the PECL AMQP extension or alternatively it has experimental support for the PHP library for AMQP - I would normally prefer the PECL version but ran into version compatibility problems, missing manual pages, and decided that a pure PHP solution might be more portable and perhaps I would just add the experimental branch to my composer.json file for this project.

  5. Git Log All Branches


    I can't be the only person who always seems to be switching between multiple development branches. Sometimes I get distracted for a few days (I'm also part time, which doesn't help!) and then I can't even remember what I was doing or what the branch was called.

    The remedy for this situation? The --all switch to git log.

  6. Ubuntu and the X220T Touch Screen


    I have a thinkpad laptop with a touchscreen and a swivel so it can fold up and pretend to be an oversized tablet. I like it a lot, but the touch screen interface hasn't been all that useful since I normally use this machine docked and then it maps the …

  7. GitHub-Powered Changelog Scripts


    My current project does periodic releases, we build a few things, then we work on getting a bunch of user feedback and changing/fixing things before we actually release. This means we need to be organised with tags and branches. We're using GitHub for collaboration, including our issue trackers, commits which contribute to an issue have the issue number in the commit message, and when a branch merges in to the main line, we use the "fixes #42" notation to simultaneously close off the issue that it relates to.

    This has been working pretty well, and today I got the question "what's new since I last saw this project?" - so I created a changelog. It's rather rough-and-ready but I had fun so I thought I'd share.

  8. Splitting And Combining Odd/Even Pages With Pdftk


    I'm working on a fun printable project at the moment, but part way through I realised I would need to process odd and even pages of the document separately. So separately, that I split the doc into two separate ones, with odd pages in one and event pages in another - and then had to recombine them. Here's the commands that I used, with an excellent tool called pdftk.

  9. Zend Certified PHP Developer 5.5


    Yesterday I updated my previous ZCE certificate to the Zend Certified PHP Developer qualification (the new ZCE for PHP 5.5 also got a new name). Since the ZCE 5.3 exam is no longer available and I work with various clients to prepare their teams for these certifications, it …

  10. Upcoming Git Courses


    Three git courses are coming up in the next few weeks, and a few people have asked me which courses I'm running, so here's a quick roundup (feel free to drop me a line if you need any more detail):

    • Dublin, 30th January: Git and GitHub Foundations
    • Dublin, 31st January …

  11. Git, Vimdiff, and Merge-Base


    git merge-base is this week's favourite git command. I use it to show me in a vimdiff everything that has changed on a particular branch since it was created. This took a little bit of looking around to find how to combine the tools, so I thought I'd write it all down in one place.

  12. Hiding Sections With Rst2pdf


    I've been using rst2pdf for slides for a year or so, but recently I've been converted to using it for everything from documents to emailed reports to handouts. Along the way there were a couple of cases where I wanted to create two similar documents, but one needed to omit some details. A great example is my ZCE questions pack, which when updated to PHP 5.5 I converted to restructuredText. By showing/hiding different sections of the document when I generate the PDF, I can maintain the questions and their answers side-by-side, then create the documents containing questions and answers separately. You could do the same with adding a notes field to slides that are hidden when presenting, but available for handouts.
