Slide Markup with LaTeX: First Steps

Since starting to create (a large number of) presentations using LaTeX, I’ve been impressed at how easy this is to pick up and also how quick it is to work with marked up content rather than dragging objects around in Impress or equivalent. With that in mind, I thought I’d outline the very basics of the markup (with probably more snippets to follow as I discover them).

Start at the very beginning

First of all, LaTeX templates are fussy things, start with someone else’s outline (for example the one Dave posted, which I use), or one you made earlier. There is some preamble and then the main contents of the presentation go between the \begin{document} and \end{document} bits.

Creating Presentations with LaTeX

This spring/summer, I’m giving quite a few talks at conferences, and I have a number of my own clients that I’m writing new training materials for. That’s a lot of content in total and so, inspired by Dave’s article about LaTeX and powerdot (and with some help from Dave himself!), I’ve started to write my own presentations this way too.

Getting started was a struggle, I’ve never really used anything like it before and if there’s one thing LaTeX doesn’t do well, it’s error messages! The blog post I linked above has a sample presentation in it and I used that as my starting point. The source code goes in a file with a “.tex” suffix, e.g. presentation.tex. I then installed the texlive-latex-extra, latexmk, vim-latexsuite, latex-fonts-recommended and texlive-fonts-extra packages from aptitude, and generated a PDF by running:

latexmk -f -pdfps presentation.tex

Using Persistent Storage with Gearman

I’m using gearman for the first time in a new project, and two things in particular were bothering me. Firstly, there doesn’t seem to be a built-in way to see what’s in the queue. Secondly, if the gearman server dies (which seemed quite likely when I was first getting to grips with this stuff and writing really buggy code!) you lose your queue. Therefore I decided that I would switch gearman over to running with persistent storage. Continue reading →

Mercurial Primer

I am a source control nut, I’ve been speaking about Subversion for years, I co-lead an active open source project which uses git and GtiHub, and I’ve also dabbled with Bazaar. So far I’m feeling the limits of Subversion, loving the code-hosting features of some of the DVCS tools, and hating git and github in equal measure (don’t bother to try to talk me out of this, I’m well aware the problems are mostly on my side). I don’t know anyone else using Bazaar in the PHP community but I do know quite a few people raving about Mercurial, or Hg. This post is a quick introduction to the commands I have been using since I started trying out Hg and BitBucket for myself.

Ticket Giveaway: DC4D:2

Did you know that there’s a second edition of the DayCamp 4 Developers event coming up in March? The daycamps are a chance for developers to invest a day in their careers, wherever they are, focussing on the soft skills we need to grow beyond coding monkeys and into accomplished and upwardly-mobile professionals. It’s a virtual conference, so you can join us from anywhere in the world!

In the new edition of DC4D, I’m giving a session entitled “Could You Telecommute?”. I have worked from home for three years and if there’s one thing I’ve learned along the way, it’s that it isn’t always easy! Telecommuting doesn’t suit everyone so if you think you’d like to work this way one day, then I hope to give some pointers for how to tell if it will work out, or how to make it work for you. The event is on March 5th but there are also video-only tickets for those people who would rather watch their sessions back at their own pace.

I have a ticket to give away, so if you want to be my guest, leave me a comment and tell me why I should choose you! NB the tickets are only $35 so this isn’t quite as impressive as it might sound, sorry!

I’ll pick winners on 26th February, with a week to go to the event.

Book Review: The Passionate Programmer


I’ve been putting off writing this post, because I wasn’t sure I could do the book justice, but I read and really enjoyed “The Passionate Programmer” last summer, and I’ve been dipping into it again and again ever since. The book was actually a recommendation from Travis Swicegood, after he saw me give my talk Open Source Your Career. It seems like it’s not a well-known title so I thought I’d share my thoughts on the book and what I got from it.

Installing Gearman for PHP and Ubuntu

I’ve been using Gearman lately in a project that I’m working on, and of course a month later when I came to deploy the code, I had to look up all over again what was required for a gearman server in order to put it on the new platform. Here is the short version for my future reference (and yours, if you like)

Why I Love Unconferences

I’m seeing increasing numbers of unconferences popping up and I must say I’m quite enjoying them. Last year I went to OggCamp, we included an unconference at DPC, and now there’s a PHP-specific event coming up in Manchester: PHP Unconference Europe or phpuceu. I really like unconferences but I think sometimes people don’t know what to expect, so here’s an outline.

Using gnome-keybinding-properties

ubuntu netbook logoLast week I reinstalled my aspireone, which I’ve had for quite a while but which is really excellent for events. I put the latest Ubuntu Netbook Remix onto it and it installed like a dream, with peripherals and powersaving all working correctly. It says something about the positive experiences I’ve had with *buntu installs lately that I even did this over the wifi!

The weird thing was that I don’t really use Gnome on other machines as I prefer KDE, and I hadn’t seen the Unity desktop before (as I understand it, this is a lightweight gnome replacement – it still looks and smells like gnome to me), so there were a few things that were “missing” as far as I was concerned. Easily the most annoying is the Alt+F2 shortcut, I don’t really care what GUI I’m using, I mostly just run things from that! I also realised that I now had workspaces, but that there was no keyboard shortcut to switch between them (I don’t use a mouse, so it’s keyboard or nothing for me).

Enter a wonderful utility called gnome-keybinding-properties.
