PHP 5.4 Benchmarks

Today I’m giving my first ever talk at OSCON – about PHP 5.4 (I’ll also be giving my second ever talk at OSCON, about RESTful services; it’s a busy day!). My talk includes some benchmarks which I thought I’d also share here, mostly because I like pretty graphs – and this one is pretty:

Lesson Learned: Look in the Pull Request Queue

If you follow me on twitter you might have seen some overexcitement when I managed to edit and compile a vala application recently. I use a great deal of open source tools, but many of them don’t seem open to me, because I don’t have the skills to modify the code. Regardless of that, it’s still vitally important that it is open (this is a whole other post and I’ll avoid that tangent right now). Continue reading →

Monday Git Tips

One project I’m working on at the moment involves finding my way around changes in a codebase that isn’t mine – and it’s quite large. I was doing pretty well with a combination of git log and git show and in particular two of my favourite existing tricks:

Pushing to Different Git Remotes

Just a quick tip because I’m working on a different git workflow at the moment with one of my clients, and it struck me that this usage pattern is something I don’t usually write or speak about at all. Most git setups have one “main” repository, and either:

  • there is a gatekeeper that manages merging to here
  • all developers have write access

In this case, I’m working with the second option, so I’m pushing to the upstream repo. I’m also pushing to a live repository as well, so I thought I’d outline the commands I’m using. The setup here is the main github repo, and I have my own fork of that, which is cloned onto my laptop. I can push to both that main repo, which I’ll call “upstream” (because the github documentation does and it makes sense!) and another repo that I’ll call “live”. All in all it looks something like this:

Bit.ly API: Bundles and Short URLs

I am a huge fan of bit.ly and use their tools for a wide variety of different things. They recently did a big relaunch with some lovely new features, which are for the most part pretty good, but which are inaccessible in places. In particular, it seems that there aren’t any short URLs for the bundles – which is annoying for me as I use that feature a lot!

To get around this, I used their API to make a page which lists my bit.ly bundles, and creates shortlinks for each of them (once you’ve created a shortlink for a given URL once, bit.ly just re-uses the same ones the next time you ask to shorten the same URL, so this is less silly than it sounds).

In case the code is helpful, I thought I’d share. Continue reading →

LAMP and Beyond, 30th June in Manchester

Just wanted to share news of an event that I’ll be at in a couple of weeks: LAMP and Beyond. This event is organised by PHPNW and held at Madlab in Manchester on June 30th (it’s a Saturday).

The idea is that we bring together a bunch of interested developers plus a few people who know something about some of the technologies which are often used with LAMP but aren’t part of the acronym – and work on … whatever you want to work on! Between us we’ll be able to advise on choosing and implementing new technologies for solving particular problems, troubleshoot some sticky issues, and maybe whip up some new projects to give you a chance to play with something new and shiny!

If you want to join, you can get tickets (but be quick, there aren’t many left) on eventbrite: http://lampandbeyond.eventbrite.com/ – see you there!

Proof that PHP 5.4 is Twice as Fast as PHP 5.3

So recently I was working on some benchmarks for different versions of PHP, because I heard that PHP 5.4 is “faster” and since I’m a data geek I want to know how much faster! Now, PHP 5.4 is, in general, faster than PHP 5.3 but not twice as fast* unless you pick a use case which has been particularly optimised.

My first attempt at benchmarking the two versions produced this:

Fetching Your Talks from the Joind.In API

I’m a regular speaker at a variety of (okay, mostly technical, so not really that varied!) events, and I submit talks to many CfPs (calls for papers). Whenever this happens, I tend to look back at whether I have any existing talks that I gave and liked and which would be a good fit. I use my joind.in speaker page for this: http://joind.in/user/view/110 as it’s simpler than dredging through my directory of talks/articles on my hard drive (this is now rather large and unmanageable!).

I’ve recently been thinking that I should also do a better job of linking through to the various talks I’m giving/have given – and at around the same time I was contacted by the good folk at mojoLive about integrating against joind.in. To cut a long story short, the joind.in API now has the functionality for users to retrieve their list of talks! Continue reading →
