Despite having been toying with MongoDB and PHP for quite a while, I've only just picked up and read the "MongoDB and PHP" by Steve Francia, published by O'Reilly (disclaimer: I've collaborated with Steve on a few articles and he sent me a copy of the book to read)

Recently I've been drawing a few different kinds of diagrams for a book I was writing, and been using graphviz to create them. Since I struggled a bit to get them going the way that I wanted them to, I am sharing them here (as much for my future self as anyone else visiting, but if they help you too then that's excellent).

This blog regularly features posts which are rather niche, incomplete or in some cases simply misleading (not intentionally, I promise!). Often I post something, and then discover there was an awful lot more to know, and find that people add all kinds of constructive suggestions, resources, and other goodness in the comments.

I seem to blog about graphs a lot at the moment, but that's because I am seeing a lot of them, with one thing and another. I recently added some little bubbles to the line graphs produced by Bitestats (obligatory elevator pitch: one-page, simple summary report pull from your google analytics account). I think they are kind of cute.

Once I got going with them, they were actually pretty straightforward. You can actually add all kinds of markers to your google chart, complete with funky icons and customisable colours! The code I added to make these is simply:

All we have here is a simple specification of which kind of bubbles I want, the label for them and which data series (ds) and data point (dp) to attach it to. I generated the bubble tail directions sensitive to whether they were a min or max label, and which half of the graph they are in.

I'm delighted to announce that I'll be speaking at OggCamp this year. This is an event that I've attended both previous years, and one that I always seem to get a lot out of. It's an open source, anything goes, unconference kind of event. Except that this year there is …

This year I moved my whole presentations toolchain over to LaTeX and PDF, and where I added diagrams (which doesn't happen a lot!) I used graphviz to generate them. Graphviz is a way of describing items and their relationships in a textual manner, and rendering them into a graph - and the results can be saved as an image, or included in LaTeX documents.

I found graphviz frustrating at times but on the whole it draws clean, symmetrical graphs far beyond anything else I can manage, even if I do use a mouse or tablet. Since I'm not able to use a pointing device on a regular basis, and I'm marking up my presentations in text also, it turned out to be a really good fit. I thought I'd share how I got on with it and some of my own graphs - as much to remind me next time conference season comes around as anything.

I spent last weekend in lovely Bath, but I didn't get to see much of it as I spent all three days building a RepRap, or Replicating Rapid Prototype. This is a 3D printer that can print plastic into any shape you can think of (and some that I definitely didn't). The Masterclass was organised by EMakerShop and brought together a bunch of people with ties to the local area who are all active in the project itself.

I'm working on a book at the moment, and there are strict guidelines on formatting. One thing which is tripping me up is that all code samples must use two spaces for indentation. I normally have my editor set to 4 spaces, so I was looking for a good way …

I am a female speaker, and a software developer, which puts me in a fairly small minority at the events I usually attend (I'm a PHP consultant based in the UK, to give you an idea of what kind of events those are). Recently I've been asked my opinion more than once on the issue of women speakers being in a minority at technical events, and I've also been the "token" women speaker at a technical event.

The worst thing you can do is find some random, underqualified person who represents the demographic you want to include, and put them on the stage. Although gender is often the issue we hear most about, the same applies to anyone who isn't a young, white male; it's just that gender is easier to see and talk about than either age, ethnicity, sexual orientation, or anything else, and also since I'm a young, white female, it's the only aspect I can comment on.Women are in such a minority that they are, almost by definition, representative (see http://xkcd.com/385). Anyone who sees your randomly-selected woman speak will simply go away thinking that women aren't really good at speaking.

Apache on Debian. Ubuntu

When I first started using Ubuntu, I was coming from a distro journey that started with FreeBSD and took in Mandrake and Gentoo along the way; I hadn't worked with any Debian-based systems before and was new to the way that Apache is configured on those platforms.

Recently I've been writing a LOT of LaTeX for slides (using powerdot) and I'm trying to collect some of what I've learned here so I can refer back to it later (and so it'll be in words I can understand, some LaTeX documentation is slightly too academic for my tastes!)

I find the default formatting for table output in LaTeX can look a bit ... squashed, so I always precede my tables with this:

I'm currently delivering all my talks with PDF format slides, using Jakob's PDF Presenter Console, which is awesome but lacks a "goto slide" button and is a little slow to click forward. It doesn't matter for a short talk but I had 200+ slides for my ZCE preparation tutorial at the Dutch PHP Conference and I was concerned about losing my place! Therefore I split my slides up into several decks, but still need to publish them as a whole.

For years I've used PDF Shuffler for this sort of thing but I wondered if there was an easy way of doing this from the command line this time, since I literally wanted to glue together a bunch of files one after another. Predictably, there is and it's called pdftk - the PDF Toolkit.

As a lead on an open source project, I spend a lot of time merging awesome contributions from our community into our main repo on github. Sadly, some of them are slightly less awesome (rarely but it does happen) and I sometimes need to unpick what happened to understand the …

Recently I've switched how I prepare and deliver presentations, using LaTeX to mark up the content and producing PDF slides from that. Which is great but I miss having some of the during-presentation functionality of LibreOffice such as a timer and being able to see what's on the next slide …

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).

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:

Recently the nice folks at Addison Wesley sent me a review copy of "The Developer's Guide to Social Programming" by Mark Hawker (you can find it here on amazon). This is right up my street as I'm doing so much with with APIs, social and otherwise, at the moment and the book covers things I'm using such as OAuth and google's services.

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.

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.

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 …

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.

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)

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.

Last 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.

Recently I moved some podcasts on to Amazon Simple Storage Service, or S3, which I know is great and easy to use, and I've used it with some wrappers, but never directly until now. It turns out, unsurprisingly, that S3 is great and easy to use :) I used s3cmd from s3tools - a collection of python scripts that made this really really easy. Even better, I'm an Ubuntu user so s3cmd is already packaged for me and I simply installed with:

Google Charts API is a nice, freely available tool for creating really good-looking graphs very painlessly. Don't be fooled by the "API" bit though, there is no need for advanced understanding of HTTP here - you generate most graphs just by adding parameters to a URL! In this post we'll take a look at a few different ways to generate charts.

I spend a lot of time at command line, and bash records the history of all the commands I've typed and puts it in .bash_history (there's a limit on how many it stores but for me it goes back a few days). I find it really useful to look back …

I'm deeply involved with an open source development project (joind.in, the event feedback site) and we recently made the decision to move our issue tracking away from GitHub (because it's awful and meets none of the requirements for a bug tracker, but that's a post for another day). In order to make this happen more smoothly, we wanted to migrate our open issues from github (to JIRA Studio, since Atlassian generously provides accounts here for worthy open source projects - thanks Atlassian!).

I looked around for some export functionality for github but I got a lot of posts complaining it wasn't there. Since I hate applications that take your data and refuse to let you remove it, I was disappointed by this news but further inspection showed that although there might be no "export from github" button, there's an API that more than has it covered. The API returns JSON which is easy to work with from many programming languages, and is perhaps even more powerful and flexible than the simple export I initially expected, so here are some examples.

Recently I've been working on a project using Google Charts API and I absolutely love it. It makes pretty graphs and shows data really nicely - and it's very painless. I did trip over a little trick today though which took me a little while to work out, so I thought …

I'm an Opera user but I use a number of applications from the command line, and often I want to launch links from those applications into my web browser. I've just switched over to reading my feeds using canto (web applications are becoming decreasingly accessible these days, although I'm saving …

In June 2011 I'll be speaking at a rather awesome event called DIBI at the Sage in Gateshead (if you're a southerner, then Gateshead is near Newcastle, which is "up north"). DIBI stands for "Design It, Build It" and has two tracks, one focussing on development and one focussing on …

It is pretty common when using OAuth for there to be a relationship between the provider and consumer; as a consumer you usually register with the provider to obtain a consumer key and consumer secret. Google's APIs however do not require this. It is recommended that you register your application …

When I spoke at PHPNW10 in October, I talked about teams, skills and the importance of benchmarking things in order to illustrate improvements. If you didn't see the talk, the video and slides are linked off the conference site. In particular I talked about the importance of analysing skills in a team, then improving them, then analysing again to see how things had changed. This post is about that process, some techniques that might apply, and what to do with the results when you get them.

Recently I've been looking at different vim colorschemes, after using vimdiff and finding I couldn't see half of the code. I've been using relaxedgreen for ages, and it is excellent but I find the blue really hard to see on my black background so I was in the market for an alternative.

I noticed the other day that the cheat sheet I have on this site for curl doesn't show how to use cookies, so I thought I'd remedy that omission, and quickly! Being able to use the command line to authenticate and then go on and use part of a site …

When I work on database designs, either on my own projects or as advisor to others, I often find people very reluctant to use an enum type for any columns. Now, I'm not about to advocate the gratuitous use of an enum column, they definitely have some pitfalls, but I think it is important to understand these rather than just shouting "enum evil!" if anyone should mention them.

There are cases where an enum is the correct choice for a particular type of data, so let's look at what an enum type actually is and does.

I gave a talk at the weekend which talked in outline terms about Return on Investment or ROI. It was a keynote so I skated over the details, but I wanted to include a specific example to illustrate what I meant.

Imagine the scenario where, given 3 days to work …

I'm an Opera user, and one of the reasons I am is that I can control my browser entirely from the keyboard. I think everyone uses browser keyboard shortcuts, and in a lot of ways Opera has similar functionality to other browsers, but it also has keyboard spatial navigation, meaning I can jump to the next element in whichever direction I choose. Opera also has per-site preferences, which actually make the web usable for me.

I was playing with pecl_oauth last week (more about that in a later post) and when I tried to install from PECL, it grabbed the files, ran the configure step but stopped with an error status during make. This is bad news for those of us who are ubuntu users …

If you read this site purely on a feed reader, this is probably irrelevant to you, but I recently made some changes to this blog and thought I'd post about how I worked with Serendipity to achieve them, mostly involving some template hacking and using a plugin to make a particular area of the site editable through the admin interface.

This review has been in my drafts folder for 9 months, because I didn't feel I was doing the book justice. It seems like I never will, so here it is - as it was written then, but hopefully still useful and relevant to someone

I bought this book last year when I was still working at Ibuildings, and my role changed a lot to include events and community representation. Before that I was doing entirely PHP development and it was around this time that I noticed myself saying "has everyone forgotten I'm actually a developer?" a lot! So I quickly decided that I needed a copy of The Art of Community, a book by Jono Bacon published by O'Reilly. Actually, I should thank O'Reilly at this point for publishing the book and even more so for sending Josette and her book stand to conferences - I was able to buy the book and it came with a pep talk :)

Increasingly I find a very binary split between the professionals I come into contact with. One group of people are very database-aware and take the design of their storage quite seriously - with good results. The other group are more concerned with the functionality of their application, and have little regard for how it is stored other than considering it a keeping-place and making useful table and column names.

Too often though, they don't think about how that data will be retrieved or what the implications are when it gets beyond the thousand records that were used for testing. This is where having an idea of how the data will be retrieved can really help application performance. (note: this article is aimed at users of traditional relational databases, and ignores all other possibilities). This post takes a look at the various index types and when to use them.

Last week I was preparing a training course for a client, and I wanted to print the slides nicely for the attendees to refer to and make notes on etc. The slides were done, I'd talked to my friendly printers (Mailboxes etc in Leeds) and all I needed to do …

This is a trick I use when deploying websites so I thought I'd post it here for posterity. Actually, technically I stole it from someone else but for now let's pretend it's mine (thanks @__kb!)

When I deploy an application, which is almost invariably a PHP application, I like to …

A couple of weeks ago I gave a lightning talk at the PHPNW user group entitled "Geeks Can Write" or "Can Geeks Write?" - basically shooting down the worst of the excuses for not writing that I've heard and asking everyone to give it a shot! If you are interested, then …

Perhaps this is more of a rant than a post but I do keep running into issues with databases with names that are inconsistent - which makes them really difficult to work with. When designing a database, there are a few points to consider:

Recently, a github project that I contribute to, joind.in, moved from an ordinary github user account over to an organization. Getting contributors moved over is pretty straight forward, I have a fork of the main repo on github at http://github.com/lornajane/joind.in and that updated to …

Last weekend I was at WorkCampUK in Manchester - it's taken me this long to writ the blog post because I needed time to download my photos, however I've now done that and I didn't get anything at all worth publishing, d'oh!

I am a wordpress user and even wrote a …

Recently I've been doing more git than I ever intended to, working with the Joind.in codebase, contributing and managing contributions to that. I quickly realised that I needed to make changes on branches, and since I'm new to git, it took a while to figure some of this out …

I use Skype on linux and the client is quite limited in terms of buttons etc, which doesn't bother me at all since I don't use a mouse unless I must (answering skype calls forms a lot of the "must"!). In group chats however, its annoying to have the alerts …

Describing something as a "poor man's" version of the thing is to say its a bit of a cheap or short-cutting version. I thought I'd share some VERY poor man's caching that I came up with the other day.

To set the scene - I'm hosting the Dutch PHP Conference this …

A couple of years ago, I attended ZendCon for the first time. At that time, the only laptop I had was a work machine weighing 5kg, and I was staying in a different hotel from the main conference - so I hastily bought pretty much the first non-ee netbook on the …

This is a podcast version of my rant-in-the-bar advice to anyone thinking about speaking, or wondering how to begin. Personally I think many more people could be sharing their expertise at events than actually do so, and I would really like anyone who wants to get involved to have a …

Last weekend I went to Liverpool (my first visit there!) to attend OggCamp for the second year in a row. This isn't a part of the software community I normally interact with, but I accidentally went to a LUGRadio event once a couple of years ago and have been hooked …

Recently I've been using bzr-svn when I'm working with subversion repositories; its a bridge between a local bzr repository and a remote subversion one. I travel fairly frequently and the pain of being disconnected from the server, unable to diff or log, and then either unpicking everything I've done or …

Here is a quick howto on using a config file to associate an SSH connection with a particular identity file. When I ssh directly from the command line, I can specify the port, identity file to use, and a whole raft of other options. However these options aren't available when …

Recently the kind folks at Prentice Hall contacted me to ask if I'd like to read a new publication of theirs , "Making it Big in Software". It sounded like something I'd be interested in and the copy duly arrived. My first impressions were of a wordy book, very much aimed …

This is a post in celebration of Ada Lovelace Day, recognising women in science and technology. Last year I wrote about Kathy Sierra for Ada Lovelace Day; this year my subject is someone much closer to my own life.

At work at Ibuildings recently, I've been teaching some classes on web services, and its a topic that I've spoken about once or twice at conferences. But something has always bothered me, so I find myself in the unusual position of blogging a question.

One problem that seems to need solving too often is how to keep databases in sync across different platforms, different developers working on a project, and deploying database changes along with code changes. There are lots of ways of approaching this, none of them are really excellent however and personally …

Last night I travelled to the northeast of England to speak to a thriving technical community up there called Supermondays. They contacted me some time ago asking if I could get there to speak one Monday, and last night was the night! It was a very civilised gathering, with sandwiches …

I've been having issues with the presenter console on both my ubuntu machines since upgrading to Karmic (9.10). One is a Thinkpad T400 running kubuntu and the other is an aspireone netbook running ubuntu netbook remix. Neither wanted had a working installation after upgrade and I couldn't get the …

There's a little command line utility on *nix which I use a lot - it's wc or "word count". This is especially useful to because I live in a world where everything is plain text right up until I have to send it to someone else (and sometimes not even then …

I'm an SVN nut - love it, use it, talk about it at any opportunity, can't physically write code without it. But as a telecommuting developer who is sometimes travelling around, I've been thinking for a while that one of the distributed systems would really make more sense. I tried git …

These are my top tips for getting along and meeting new people at a technical conference.

A while ago, actually quite a while ago in May, I put the Ubuntu Netbook Remix version of Ubuntu 9.04 Jaunty Jackalope onto my lovely blue Acer Aspire One netbook.

I spoke at the FOWA Tour event in Leeds yesterday, as their local speaker (they set aside a slot for each place they go). It was a great event, good atmosphere and I really enjoyed the both crowd and content. I can't imagine what the logistics for something like this …

I have been thinking, writing and speaking a little bit about web services recently, starting with a few thoughts on authorisation mechanisms for services. Today we'll look at another really important aspect of authoring web services, and one feature that will definitely get used - error handling and feedback! Having clear …

I'm surprised and delighted to announce that I will be one of the speakers at the rather excellent FOWA Tour even in Leeds on 28th May (two weeks today!). The day is like a roadshow version of the famous FOWA conferences, with a morning of (free!) cloud workshops and an …

I'm delighted to hear that the date has been set for the next Leeds GirlGeek Dinner - Wednesday May 27th 2009! I've been really enjoying this series of events and always meet some really interesting ladies when I attend these events. The idea is to get geek girls together for some …

Today I upgraded a bunch of machines to the latest Kubuntu offering, version 9.04, or "Jaunty Jackalope". Well, it was all going a bit too well and when I came to upgrade my main work machine, a thinkpad T400, I ran into problems. There are a couple more kinks …

Having been involved in quite a few service-related activities in the last year or so, I've been having a few thoughts about what I've learned from this and what decisions I make when designing a service. Hopefully there will be a few of these posts - but to start with, I'm …

Yesterday I took the opportunity to pop along to the Maker Faire in Newcastle - its so exciting to see events like these in the UK! The marquee there was pretty small but what it had was great fun. I saw several things there that had me really drooling - one was …

Today I had a big SVN merge to do - i'm at the end of a development cycle and I needed to merge my branch of changes back into trunk. I dug out my crib sheet for merging and tweeted that I had - and a few people asked me to blog …

In January, Kevin and I went to Peru for a few weeks - to visit our friend Cally, and we did some touring while we were there. Between the two of us, we took almost 3,000 photos. Which is way too many to make granny sit through when we got …

On 18th February, I'll be making an appearance at Geekup Leeds, to give a talk entitled "Linux-Fu for PHP Developers". Basically this is a tour of some of my most-favourite command line tools available in Linux, and its a pre-cursor to the talk I'll give later this year at php …

I run the website for my local netball club and when I implemented this site I chose Joomla! to run it on. It seemed like a good idea at the time, in fact I even thought some of the other club members might log in and type into the user-friendly …

I've been using KDE full-time long enough that I ought to know this, but I had to look it up! I was working in a shared location and I wanted to lock my session when I walked away from my machine. There's an option in the start menu but the …

Since I started using Linux on the desktop, I've always used katapult to launch applications. However I have another machine that doesn't have katapult and (since I don't use a mouse) I've always used Alt+F2 to launch appilcations on there. Well, since installing Kubuntu Hardy Heron I notice it …

A while ago I posted about screen, and included my .screenrc file. I got some teasing for this, since the tabs show up pink. In fact this .screenrc file is one I stole from somewhere a few years ago and didn't really think much about the colours. Since then I've …

We had some fun and games with our house server recently, when one of its disks died horribly*. I've only just got around to sorting out the backups again now, which use an external USB hard drive and rsnapshot. I started by reading my earlier rsnapshot post and also the …

Wordpress is a fine basic website tool, and I've used it for a few different odds and ends. One thing it does have that suprises me every time is that it uses a setting for its web address. So as part of the install, it sets this setting and then …

I'm getting quite excited now about the next Leeds Girl Geek Dinner which is next Wednesday (3rd December 2008). Got some cool speakers by the look of it - I know Monica (and she is fab) and from Katie's bio we are in for a treat. Also I have been promised …

Announcing the second girlgeek dinner in Leeds! The event will be Wednesday 3rd December, at The Loft Leeds and tickets are available now, priced at £15. Monica Tailor from Kilo75 will be speaking at the event, and it will have quite a Christmassy feel.

The rules of the girl geek …

I recently upgraded the copy of Opera on one of my machines, only to find a few things about it which had changed from previous versions were driving me mad!! Immediately noticeable was that the address bar autocompletion seemed to have gone completely nuts. It was autocompleting all sorts of …

I use a lot of apps from the command-line, partly because command-line stuff is the same on every system, and partly because I struggle to use a mouse for RSI reasons. Unsurprisingly, the best keyboard-navigable apps are ones that only use the keyboard in the first place! One app that …

Speaking at conferences is a great way to share ideas and meet people - but actually getting the opportunity to do is a little more tricky and usually involves proposing a talk. In the last year I've attended IPC in Germany and PHP London, spoken at DPC in Amsterdam, submitted talks …

rsnapshot is a great tool that I use for all my backup stuff, its really easy and seems pretty robust (or rather, I haven't broken it yet!). When I set it up most recently, I discovered that it has a very useful flag, no_create_root. The problem I often have is …

I was recently installing the VMWare tools onto a debian etch virtual machine which I downloaded from the thoughtpolice.co.uk site, and I ran into problems. When the installation instructions from thoughtpolice say to type

mount /dev/cdrom /mnt/

This gives me an error about "You must specify the …

I am an irssi user - I have issues with mice (I don't use one) and so the text-based IRC client works wonderfully well for me. It also looks less like a chat client and more like I might be working on a terminal screen, which was more useful before I …

I can't remember another post which was in both the "tech" and "craft" categories - so no complaints from either camp please! Last week I became the new owner of an acer aspire one netbook/ultra mobile PC. Its little, blue, and very cute! If you want to skip the tech …

Irssi is a fabulous IRC client, which runs on the command line. I'm sure I don't use half the features it offers but its very stable, unintrusive ( you can run it in a background terminal, or even leave it running in a detached screen process ), and frankly excellent. Because I …

I have a scribbled sheet on my desk, which is my "cheat sheet" for curl, its really short and I thought I'd put my notes here for safe-keeping. If you're visiting, then I hope they help you too.

Last night I gave a talk at the Leeds Girl Geek Dinners entitled "Professional Development for Girl Geeks" - and you can find the slides on slideshare if you're interested.

Most of what I said wasn't on the slides, but the gist of it was along the lines of:

• Use the …

Once upon a time there was a girl geek called Sarah Blow, and she wanted to hang out with her girl friends and geek out at the same time (and who wouldn't?). So she founded the phenomenon of the Girl Geek Dinner in London. Well this great idea has spread …

I'm attending LUGRadio Live UK this weekend, in sunny Wolverhampton! I'm slightly concerned that this might be too geeky for me and I might be scared but there are people I'd like to meet, the talks look interesting, and I can imagine it will be a pretty good crowd. If …

I was running an import script today taken from a mysqldump from another user, when I saw an error that looked like this:

ERROR 1005 (HY000) at line 123: Cant create table  (errno: 150)

This is caused by a mysqldump or export process exporting tables in alphabetical order and not …

When development teams have people working on a variety of platforms, its pretty common to end up with wrong line endings. In vim these will look like ^M at the end of each line. To get rid of these line endings you can use the following command (in command mode …

This site uses a blogging platform called serendipity which is a nice little tool and I've been mostly happy since moving across from textpattern (I did write about the experience). Recently however, a few things have been going wrong with the feeds.

I edited an old post, because the image …

I've had this error more than once. On a debian virtual machine, with Zend Core installed, and when mysql doesn't restart when the machine reboots. It looks something like this:

debian:/usr/local/Zend/mysql/bin# ./mysqld
080627 12:31:16 [ERROR] Can't find messagefile '/usr/local/mysql/share/mysql …

So, at the Dutch PHP Conference, they were making a video and they interviewed me. The video is at http://www.bachelor-ict.nl/dpc and it is also featured in this article on DevZone which is exciting! The video is mostly about the PHPWomen organisation, rather than my talk but …

Well, its a misleading title because the day is only half over but the Dutch PHP Conference 2008 is well and truly underway! Today I've been in the Zend Framework tutorial given by Matthew Weir O'Phinney, which is a full-day session. Its been excellent - with some concepts, some examples, and …

Today I leave for Amsterdam, to visit the Dutch PHP Conference where I will be getting my first experience as a conference speaker. It would be fair to say that I'm very nervous - its a high profile event and the other speakers in the lineup are pretty amazing!

When I …

Recently my friend Deb, Leeds Geekup organiser and Ruby developer, gave me two baby courgette plants ... she even went so far to photograph me, slightly tipsy, leaving the pub to get the bus home:

I did get the plants home intact and planted them out. I was going to post …

So last night, more or less on a whim, I popped to the Geekup that was on in Manchester. I was slightly alarmed when I enquired at the bar where the event was and was told there was nothing like that booked for that night ... anyway I wandered outside and …

Last night I attended and spoke at the First Sheffield Geekup held at the Fat Cat in Sheffield. My talk was entitled "Deploying Web Projects with Subversion" and you can see the slides for that at http://www.slideshare.net/lornajane/deploying-web-projects-with-svn/.

Overall I think the event was well-organised, there …

I was very pleased to hear that Sheffield is getting its own Geekup event, and that it starts next week on 7th May and will run on the first Wednesday of every month. I was even more pleased to be asked to speak at it - I'll be giving a 20 …

Since SugarCRM only works with PHP5 in non-WSDL mode, I had to create all my calls from scratch. The SugarCRM documentation is somewhat minimal, as I may have mentioned, and I found I was mostly reading the WSDL to figure out how to format my SOAP calls. I've put together a post with working examples but I've also assembled a list of the data types needed. Click through to read more.

By popular request, here are some examples that worked for me when using the SOAP API offered by SugarCRM. Its nice that there is an interface, but it isn't brilliantly documented or nearly as widely used as it should be!

SugarCRM can't talk to PHP 5 native SOAP libraries in …

I recently did some work with Debian Etch virtual machines which I downloaded from the good people at thoughtpolice. Here are my notes on getting the VMWare tools added to that machine.

To be able to do anything interesting with a virtual machine, you need to install the VMWare tools …

I keep having a problem with my virtual machines. I'm running kubuntu but the virtual machines are on an NTFS partition (because I use them from windows occasionally). The error message appears at startup and goes like this:

I did mention recently that I had arranged to speak at the local GeekUp group. Well, the event itself was last night and although I did have speaking nerves I think it went OK.

I've uploaded the slides I used to Slideshare, so you can find them here. The talk …

This week I will be giving a 20:20 talk at the GeekUp event in Leeds, entitled "Enterprise Web Development". The 20:20 talk format allows talks with 20 slides, with 20 seconds allowed for each slide. Wish me luck :)

If you're local to Leeds, I'd love to see you …

Whenever I attend a conference or other geeky gathering (GeekUp for example) I'm often asked for my card ... but I don't have one. I don't have work business cards, because only sales people need those, and I don't have personal ones because I don't freelance (or not usually). I finally …

On Feburary 29th the PHP London 2008 conference will take place in London. Things have been very busy for the guys organising, there have been a few tweaks to the schedule but its looking like things are coming together nicely. I'm all set and have booked tickets and a hotel …

Today I was asked to add PDO support to PHP on our development box, which I thought was running Ubuntu Feisty Fawn. The first problem is that it's not running Feisty Fawn, its running Edgy Eft, which is an older version. The next problem is that the PDO libraries weren't …

I've had a few requests recently to exchange links or to add people to my blogroll, its a way of giving a bit of kudos to people that you admire and whose work you read. The thing is, I don't have a blogroll, and if I did I fear it …

Most people know that I’m active in the phpwomen community, women in technology is something that I really believe in but won’t start ranting about right now (or I’ll not get round to what I was going to say!).

Today I’m getting to grips with irssi …

I’m planning on migrating this site to a new platform soon, I’ve been looking around for an alternative to textpattern. Textpattern has been great but I’ve kind of outgrown it. Its easy to use but a bit “fluffy” and it eats my code excerpts which is really …

Today I was using the PHP command exec() in a script, which runs whatever you pass to it as it you had typed it on the command line. Its possible to check both the output of the command and the return value, which I did since I wasn’t getting …

The other day I was helping someone post to a website that I set up using Joomla! , and thought that others might find this tutorial helpful.

Start with the “Media Manager” button on the front page. This is so you can add all the images. Directories can be added here …

There’s a new thread started over at phpwomen.org about best practices for programming with PHP, which will make interesting reading for anyone looking to improve their skills. I’ve been really brave and contributed one of the articles, PHPDoc: Comments are your friends.

People are all contributing a …

As you may remember we participated in the PHP Throwdown a while ago. Well Elizabeth has sent out the icons to competitors who successfully got through the 24 hours and submitted something which vaguely conformed to the rules. You can see ours on the left :)

I’ve run into a problem with a framework I’ve been contributing to. It has a bunch of objects, which look a lot like rows in database tables. So there are pages and each page object is a row in the “pages” table in the database, with a primary …

I started writing PHP when I was at University, in 2001 or thereabouts. Having checked the dates it looks like I did technically write PHP before PHP 4.3 was released and register_globals went out of fashion. I don’t recall it though and obviously its been a while!

Today …

As promised, here’s a more in-depth update on our trip to the PHP London Conference last week. I’m sure there are others who will write more fluently and accurately about the talks, but here’s what I brought home from it.

I’ve been away for a couple of days at the UK PHP Conference in London. Due to the unique way that train ticket prices work here, it was wildly cheaper to travel a day either side of the day we actually wanted to be in London for which allowed …

This site is run by textpattern, I’ve used it a few times and I love it. In addition you may have read about my recent encounters with Joomla! .

This week I’m trying out Serendipity for another site and its quite a change. For a start I haven’t …

This weekend, Kevin (boyfriend) and I took part in the first PHPThrowdown event. While its true that programming contests aren’t new, I haven’t seen one that seemed relevant to me for a while and they do take a lot of organisation – so kudos to the organisers including fellow …

I love PHP. I’ve worked with a fair number of languages and I have to say that I absolutely love PHP. I love its cleanliness, its elegance, and its fabulours online documentation and community support.

I come across a lot of people in various walks of life who rubbish …

Well the website for my netball club is definitely going ahead, They are even more up for it than I imagined! So you can find the new site at www.shipleynetball.org.uk and hopefully it will actually get some content soon.

Its all sorted and we’re booked onto the London PHP Conference in February. Its a bit of a geeky thing to do as a couple I suppose but I’m really looking forward to it. There are some speakers that I will be positively star-struck to see in the …

Well its early days in our relationship but so far, Joomla! and I are getting along just fine. Since I installed it I’ve had a proper fiddle with most of the bits and pieces (mostly turning things off actually!!) and now its looking much better.

Since I’ll want …

This post has been a week or so in the making, I just wanted to find the right words to tell the story. I saw a post on the PHP DevZone saying that Ligaya Turmelle wants to hear from women in PHP.

Well I hopped right across to the her …
