Announcing vbLatex v0.1

Well, after an extraordinarily long period of development (over 2 years at least), vbLatex has finally made it to a public release. You can read all about it here.

vbLatex is a relatively simple plugin that uses dvipng and LaTeX to bring pretty math rendering to your vBulletin forums. I’ve gotten a fair number of e-mails about it, as it’s the system that we’re currently using at SFN – go and visit to see it in action.

The concept is Steve Mayer’s latexrender class; I felt I could improve somewhat on the this class but right now there’s no significant improvements, other than the switch from ImageMagick to dvipng.

Right now development is at what I regard as an early beta stage. Basically, I haven’t worked on the script for a good 9 months and I don’t plan to add any significant revisions until at least July due to my preparation for exams and other committments (this blog included).

There is a good chance that this could break vBulletin at some point, and your users simply won’t be able to see any threads. If you can’t figure out what’s wrong, then feel free to e-mail me.

Anyway, enjoy, and hopefully there will be more updates to it reasonably soon!

Well, this is a first…

As some of you may be aware, I spend quite a lot of time over at SFN, mostly doing administrative work these days. We have a custom-coded LaTeX plugin which I haven’t bothered releasing yet because there doesn’t seem to be much enthusiasm for it, and also because I don’t really consider it to be production-stable.

Well, about a year ago, some guys over at the Math Help Forum absolutely begged me to help them set up LaTeX, and caved in and gave them the code. Since then, I’ve redesigned the mod, making it into a proper vBulletin plugin and utilizing dvipng instead of running through dvips and convert.

Yesterday, I received another e-mail from the Math Help Forum asking me whether I could help them set the plugin up after they upgraded to vBulletin 3.6. I responded, and, being the nice guy that I am, said I could. However, after sending the message, I decided to have a look on their site and see if anything had changed since the last time I visited.

Get in

Well, I know I haven’t blogged for a while, so whilst I’m sitting here waiting for some inspiration on the Measure Theory assignment this week I’ll update everyone who is mildly interested (probably zilch) on what’s been going on.

First off, the involuntary “get in” reaction. Last week I applied to become a peer tutor, and being the enormous idiot that I am forgot to fill in a word at the bottom (which I consequently blogged earlier). However, everyone on listy3 got an e-mail today asking whether they wanted to help out, since a ninth class has had to be created to fit everybody in. This time, I got the e-mail after about 20 minutes, and have had a response to say that I have the place. Unfortunately, the class on Monday morning is on the 5th floor Physics seminar room, but I’m not about to complain.

Anyway, apart from that I’ve been busy updating vBulletin to 3.5 over at SFN – my habitual geeky home. For anybody that’s interested in the sciences or anything else besides, come along and post some stuff. It’s good fun and we’re trying to add to the academic base of people that we have there, so I’m going to plug it like a beast.

Naturally, that’s taken up a lot of my time. I’ve re-written a mod I wrote to render LaTeX using a small PHP class. I discovered the utter uniequivocable joys of dvipng, which makes creating PNG’s so much faster it’s just utterly untrue. The class also provides a number of options (one being MathML, if I can get it to work). So that’s good.

Besides that there’s been lectures as per normal. I’m enjoying all of the courses I’m doing so far; the problem is, I don’t know which ones to drop. I’m on something silly at the moment, like 250, but if I only drop 5 modules that gets me back down the scale quite a bit. I think I may put it off until later.

Also, I put some fencing up today. And I’m going home to visit the folks later, so it’s all good. For now though, I think I shall depart to beat Measure Theory with uncountably many sticks, and perhaps an open cover or two.

Whoops (again)

Forgot to post for the past couple of days. However, I do have rather a good reason for it. In fact, I have a very good reason for it: namely GTA: San Andreas which has just been released for PC. It’s rather a good game, and has taken up pretty much two entire days of my existance to get somewhere near completion. The map is so incredibly large, and there are so many things to do that I think I may have to spend at least the next week or two trying to get to the coveted 100% mark. Oh, what a hardship.

In other news, I get my exam results on Friday which I’m currently not looking forward to. So, in order to keep my mind off it I’m going to work on the site a bit (as well as playing GTA). I haven’t got around to doing anything yet, but I’m going to try and get the Mandelbrot set generator up and running in the Projects section today. It’s a pretty cool program, but I need to optimize it and generally get it to work better. I do have a minor problem in that I forgot to set the precision of cout and cin; by default, it only reads in numbers up to about 7 decimal places, so you can’t get most of the interesting shots.

I’m also not sure as to whether I should get the Photos section back up or not. There are a lot of photos – last count, over 500 – and although I have more than sufficient bandwidth for now, I can’t help but wonder what will happen if the site takes off a bit. I’m also considering putting some kind of Google AdWords on here, but at the moment the pendulum swings towards “no”. For starters, not enough people visit the site to make it worthwile, and I’m not sure that I could get them to blend in properly. I will only put them on if it doesn’t compromise the layout of the site.

The world of maths is looking quite diverse for next year. I’m considering what modules to do for next year, and this is quite a hefty challenge – the sheer number of courses on offer makes it quite hard to make my mind up. Like most other universities, we’re allowed to choose a variety of modules in the third year, totalling 120 CATS (module points) or more if we desire. Most of the third year modules are worth 15 CATS each, and the fourth year modules 18 CATS. Now, assuming that I actually get on the MMath course – which I really hope I do – I have to take two courses from the fourth year modules. At the moment, this is looking like it’s going to be Manifolds, since it’s needed for so many other 4th year modules and a choice of either Lie Groups (taught my my tutor) or Mathematical Recipies, which is more of an applied module.

My worry at the moment is that I’m not sure which “route” I should be taking. This year, I pretty much took a 50/50 pure/applied route. However, I’m finding myself inextricably drawn towards courses that concentrate mainly on the pure. I find that they’re extremely interesting and, for the most part, make me work harder on them. Metric Spaces went really well for me – it was a really nice exam, and although it didn’t have the same insane marking that it usually does for definitions, it had interesting questions that made you think, but were still managable. I have to also admit that the applied courses are also interesting, but my concern is that I’m going to screw them up, and I don’t quite have the same understanding that I do for the pure.

Of course, the other issue here is my postgraduate opportunities. Again, assuming I get onto the MMath and I’m finding the 4th year work enjoyable and I can cope with it, then I’d quite like to do a PhD. Even if I didn’t actually go on to do research and other insane mathematics then it would greatly increase my job opportunities. However, that’s a good two years away yet; not to mention that if I don’t get on the MMath, all of this talk is a complete waste of time.

Anyway, I think that’s enough for now. I’m going to concentrate on SFN now, and try and catch up on the backlog of posts that I have to moderate. Woo. See you all later.
