Xcalc is a fairly basic calculator that allows mathmatical equations to be entered via the console or by using the GUI calculator interface.

Xcalc is based off of QuickCalc by Mark Ribau. A good portion of the code has been rewritten, and the GUI has been completely rewritten.

Usage slash commands: /xcalc /calc /=

So I was making a few relatively minor updates/changes to my mod xcalc, and as I was doing so realized that by following the original design from another person it was all out of whack. Xcalc was originally written by someone else like 3 years ago, I got a hold of it back then and there is only a very little left of his original code. But I was following similar design as that person and realized the other day that it was a bit whacked out for how it should be. Basically its several hours more worth of cleanup and writing that still needs to be done for that mod.

So in the rounds that I go on the internet I came across this article: Git vs. Mercurial: Please Relax. Had I seen this back when I was reading up on dvcs it would have swayed my decision on which one to go with back then. But since I have read it and I thought it was a well represented case between git and mercurial I figured that I would at least look into it a bit more.

Apparently at some point not too long ago Blizzard released a bunch of rules for Mods. Those rules can be found here. Now this is a good thing a really good thing for that matter as there has been a fair amount of Mods going in all kinds of directions including a couple that you had to purchase the premium version. Really it is up to blizzard to make the final determination on what kind of practices are allowed and which are not in regards to writing Mods.

In fact mac has this nifty speech recognition built-in to the OS that simply can be turned on from the preference and includes a fair decent command set. What makes it more powerful is that the command set can easily be extended by applescript and attached to individual programs. It also works fairly well with video games, like World of Warcraft and I am sure with other games. There are a few things with the speech recognition that need to be taken into consideration when using it for gaming.

So finally after about 6 months or so I got around to updating my World of Warcraft mod xcalc. Originally this mod I was using to learn a bit about lua and such, but as it turned out a fair amount of people wanted a calculator in wow and such. The update was not much more than some bug fixes I really didn't add any features to the bill, there is only so many things that I can do at this point with it that might be useful like maybe a history of the last several calculations performed, and some better control on what kind of calculations can be performed.
