Felicem annum novum habeatis!

As fzort said, I (or rather we) patched a coroutines library for C so that it'll compile on newer gcc's, and I e-mailed the patch to the maintainer.

Since I've not received any response yet, I decided to upload it to my web page.

OK seriously... is Republican candidate Ron Paul the new Linux?

Well, let's see:

froofyJIT is now on SourceForge.

TiMidity++ speedup patch redux

I rewrote the patch to use ccg instead of froofyJIT (to take advantage of being able to directly write x86 code), and posted the new patch on the timidity-talk mailing list. First response:

Does it work on the x86_64?

Oops. Um... no, not really. But thanks for asking.

There is no pitchfork. Om.

I released froofyJIT 0.26.

Also, I experimented with using froofyJIT to speed up TiMidity++ -- profiling revealed that when processing Rakhmaninov's G minor prelude, it was spending ~1/4 of its time in do_ch_freeverb(), which is static optimization hell. After some hacking, here's the result: a tidy big patch which reduces the running time on this file by ~4%.

The patch probably isn't suitable for the TiMidity++ mainline though, especially since it's in C++, while the rest of the TiMidity++ code is in ye olde C.

Update: the patch is now stashed in the froofyJIT 0.27 tarball.

In Soviet Russia... ah, fsck it

Mozilla may soon have... a JIT compiler for JavaScript? (!) I guess that means JavaScript is well on its way to becoming a Real Languageā„¢ (if such a classification makes sense).

In Soviet Russia, bugs fix You

Follow-up on the JavaScript font rendering effort:

fzort informed me that the glyph rendering was bogotified on Internet Explorer:

After more than half a day of hacking, I finally managed to stop IE from rendering the extra stuff below each glyph, and work around IE's PNG transparency bug... and in the process I also learnt about the clip: rect(...) CSS property. :)

Here's the result.

MarkAtwood: Who exactly wrote that, and where exactly did he write that? I hope it's not another of those "let's attribute this fake quote to some famous luminary" things.

Climate change can be caused by anyone or anything... except Bush et al.

Well, after fiddling around with fzort's font-packing code for a few days, I came up with this. Some sort of poor man's dynamic browser font, I guess.
