<p>P.S. I tried several ways to get the combo-snippets to put the pieces inside the right functions but failed. We'll see tomorrow if Allan (creator of TextMate) has any ideas.</p>

There hasen't been any action on that project for 13 months though, and it doesn't work on my wiki (MediaWiki 1.4.15) so I'm going to try and make it work after I upgrade to MediaWiki 1.6.3 tonight. This will be pretty cool when it works. I haven't looked at the code yet but it's only 650 lines.

How's this for an update: I'm working in Munich for the summer at a European search engine called <a href="http://www.seekport.co.uk/">Seekport</a>. The search engine isn't all they do, as right now I'm programming a desktop widget that shows live scores &amp; news from World Cup matches (in English and Arabic). I'm building it on top of the <a href="http://widgets.yahoo.com/">Yahoo! Widget Engine</a> because it needs to run on Windows. Even though I quite like the Y! Engine, I would still prefer to be coding in straight HTML, CSS & JavaScript like Dashboard programmers get to use. The Y! Engine uses XML (it is somewhat HTML-like) and JavaScript.
The place I'm living in is like a dormitory for younger people. I share a bathroom & kitchen with a German guy named Sebastian who is 21 and an artist; a stonecutter actually. I only met him briefly yesterday, but he seems nice. I'm going to teach him English, and he'll teach me German, though his English is much better than my German. It's a pretty quiet place, and we get breakfast included, dinner can be bought for €2,50, and Internet access is included as well. I brought my Mac Mini with me, and as soon as I find an AC adapter I'll be ready to go with the 'net at home. I probably won't blog again till then, since I'm at work right now.

Germany is great so far, and as soon as I get learning some German I'll be a much happier person. I consider it rude of me to expect everyone to converse with me in English, like I have to do right now.

that nothing is coupled.

My initial experience with Vista is quite good.

I really like the new Start menu and the eye-candy is fairly pleasant for the most part. Till now I’d only used RC2 on a machine incapable of running Aero Glass and it looked terrible. I switched to Windows Classic just like I do with XP. Not so with Aero at its finest though. Without thinking about the price Vista is a nice upgrade to Windows. But because of the price and uncertainty of running Aero Glass I still hesitate to urge non-geeks to upgrade.

OS X is OS X. It’s my favourite desktop OS right now because of apps like LaunchBar/Quicksilver and TextMate, a generally excellent UI, good old *nix stability, zsh out of the box! When I need WireShark or the GIMP X11 is there waiting. Mac notebooks are great and tight integration with the hardware is a clear advantage for OS X.
Oh yeah, I also have a Parallels VM for Windows 3.11. It boots in about second to the <tt>C:\&gt;</tt> prompt and then another second to type <tt>win</tt> and Windows to start. Without TCP/IP there’s not much to do though (I’m not going to write a driver for Parallels’ ethernet adapter).

On Linux I currently use Fluxbox so everything is rock solid and fast (except Firefox! ;-), but in the extremely rare event that shit does hit the fan usually only a single app will crash, though sometimes X (and hence many others) go with it. A <code>sudo /etc/init.d/gdm restart</code> fixes that. The only times I've had to hard reset Linux was because of a random bug (strangely similar to my MacBook bug) with Nvidia's driver with dual head setups. All this is pretty moot since Linux is generally just stable.

Anyway I was very pleased to see the only correct usage of the phrase "begs the question" I have seen in a while. It's a pet peeve of mine, but I have submitted myself to the fact that the phrase is so oft used to mean "begs for the following question to be asked..." that it may as well be re-defined. In its correct usage the sentence seems to hang there if you try to apply the commonly mistaken meaning to it. That's all very hazy so here's the usage in SICP (emphasis my own):

Despite my current infatuation with Emacs there are many reasons I started using TextMate, especially little time-savers that are very addictive. I'll talk about one of those features tonight. When you have text selected in TextMate and you hit say the <code>'</code> (single quote) then TextMate will surround the selected text with single quotes. The same goes for double quotes, parentheses, brackets, and braces. This little trick is one of my favourites so I had to come up with something similar in Emacs. It was easy since a <a href="http://osdir.com/ml/emacs.nxml.general/2005-08/msg00002.html">mailing list post</a> has a solution for surrounding the current region with tags, which served as a great starting point.

Parsing was the easy part. Operating on the new floats is not necessarily difficult, but it was more work than I realized it would be. I don't claim that this is the best or the only way to operate on any <code>LispNum</code>, it's just the way I did it and it seems to work. There's a bunch of boilerplate necessary to make <code>LispNum</code> an instance of the required classes, Eq, Num, Real, and Ord. I don't think I have done this properly but for now it works. What is clearly necessary is the code that operates on different types of numbers. I think I've specified sane semantics for coercion. This will be very handy shortly.

There's relatively no change in <code>numericBinop</code> except for the type signature. <code>integralBinop</code> and <code>floatBinop</code> are just specific versions of the same function.

There certainly are <a href="http://www.lshift.net/blog/2007/06/11/folds-and-continuation-passing-style">interesting things</a> to try floating around da intranet. And also things to read and learn from, such as <a href="http://cubiclemuses.com/cm/blog/tags/Misp">misp</a> (via <a href="http://moonbase.rydia.net/mental/blog/programming/misp-is-a-lisp">Moonbase</a>).

There has been a considerable amount of work done to aide in Rails development which makes Emacs especially comfortable for me. I now know why people have Emacs windows maximized on their screens. Because of its age Emacs is a handy window manager that basically eliminates the need for anything like <a href="http://en.wikipedia.org/wiki/GNU_Screen">GNU screen</a> or a window manager such as <a href="http://www.nongnu.org/ratpoison/">Rat poison</a> (which is great if you like screen), just maximize that Emacs "frame" or open one for each display and get to it. If you need a shell you just split the window and run your shell, when you're done you can easily switch back to your editing and your shell will wait in the background until you need it again. With rails-mode on I can run script/console (or switch back to it) with <code>C-c C-c s c</code>. My zsh alias for script/console is <code>sc</code> and I have other similarly succint ones for other stuff, so I took right to the shortcuts for all the handy things that I no longer have to switch applications to do:

The Rails integration is simply stunning and I could go on all day about the mature indentation support, the Speedbar and what not, but I won't. I'm fairly sure that Emacs has taken the place of TextMate as my weapon of choice now, on all platforms. And after only 2 days!
Anyway, the point of all this was to mention the one thing that's missing: support for <a href="2006.02.22-intelligent-migration-snippets-0.1-for-textmate">intelligent snippets</a> which insert text at more than one point in the document (well, they appear to do so). I don't have any E-Lisp-fu to break out and solve the deficiency but if it ever bugs me enough I might try implementing it for Emacs one day. If they were useful to me outside of writing migrations I might have more incentive to do so, but I guess they aren't useful in normal editing situations (maybe I just haven't recognised the need).

This is the beginning of a series on generating Mach-O object files in
Ruby. We start small by introducing some Ruby tools that are useful when
working with binary data. Subsequent articles will cover a subset of the
Mach-O file format, then generating Mach object files suitable for linking
with ld or gcc to produce working executables. A basic knowledge of Ruby and C
are assumed. You can likely wing it on the Ruby side of things if you know any

<p>Excellent analysis. A couple of clarifications:</p>
<p>[x, y] is used in the touchend handler because the event.touches array is empty at that point. We push the coordinates on twice to ensure that a dot is drawn if you tap the screen without moving.</p>
<p>The 10ms constraint inside the drawing loop restricts the amount of time spent drawing in order to maximize the time available to receive touch events. setInterval callbacks would never run concurrently if the loop were unbounded, but it could prevent us from receiving touch events.</p>
