The internet is littered with abandonded converters from Latex or LyX to
HTML, so why not add one more?

I've written a g-code output filter for the Python vector drawing
program Skencil, formerly known as "Sketch".
29 April 2006, 21:58 UTCOnscreen Crosshairs in tcl/tk
I was staring too long at a screenshot of a graph on some web page, wishing I
could tell if two things lined up. Well, inspiration struck, and this program
was born. Two windows—one that is one pixel wide, and another
that is one pixel tall—are created, and they follow the mouse
around every 1/10 second or so. They're displaced by one pixel so that clicking will hit the underlying window, not the crosshair.
I apologize for the changing colors, since xor isn't available with this simple method of drawing the lines, it's the only way to be sure to get contrast. I considered making the color depend on e.g., whether SHIFT is pressed, but if Tk provides this information to a window that doesn't have focus, I overlooked it in the manpages.
13 January 2006, 5:02 UTCAether: getting rid of the extra URL component
Aether likes to have its own directory component, which I called "index.cgi" on
all the sites I've set up. Finally, I have changed my webserver configuration
to get rid of this need, while keeping the old site layout working (I think).
18 December 2005, 3:49 UTCpam_ssh
The only snag I ran into on FC2 was that the script in /etc/X11/xdm/Xsession unconditionally started a fresh ssh-agent, even if $SSH_AGENT_PID was already set. I changed the SSHAGENT= line to read [ -x /usr/bin/ssh-agent && -z "$SSH_AGENT_PID" ] && SSHAGENT="/usr/bin/ssh-agent" and then everything worked. I'm now using it for console and gdm logins on one of my machines.
On FC2 I built the rpm from the tarball. It looks like FC4 has one available via yum.
Update 2006/01/09: I was having trouble with pam_ssh not leaving an ssh-agent running the next time I logged in after a crash (dead battery). I discovered that the problem was that leftover ~/.ssh/agent-* files would trick pam_ssh into thinking that an appropriate ssh-agent was already running. I now remove these files in /etc/rc.local when booting.
10 December 2005, 0:06 UTCReverse Engineering the Samsung ML-2010 laser printer
Ingrid recently bought a Samsung ML-2010 laser printer. The price was
attractive, and it seems to be a good printer. However, there is either the
choice of a an open-source driver for a different printer model, one which
doesn't support the 1200x600DPI mode, or a closed-source driver which comes on
the included CDROM.
I'm going to try to reverse engineer the new format, which is called "SPL II" in the GUI and "QPDL" in the generated file (@PJL ENTER LANGUAGE = QPDL). My approach is to print a postscript file using the binary driver, saving the result to a local file. At no time do I plan to disassemble the binary software provided by Samsung.
9 December 2005, 1:30 UTCNetflix to Aether converter
I use the code below to create the netflix sidebar on the front page of my
blog. I offered it to Michael, so I suppose I'd better post it here.
It features elementtree-based parsing, timestamp-based caching of the rss file (not the parsing result), and output into aether markup.

1 December 2005, 2:10 UTCDecyphering an assertion
A few weeks ago, I posted a humdinger of an assertion.
A little investigation shows that this is actually the very legible
assert (strncmp (repository, current_parsed_root->directory,
strlen (current_parsed_root->directory)) == 0);
27 November 2005, 21:38 UTCStippler 1.0 source release
I finally got around to writing my own dithering algorithm, so now
all parts of stippler are under a clear GPL license.
Stippler is software for turning greyscale images into "stippled" images. I have have discussed it before on my blog.
Stippler is based on the reasearch of Adrian Secord, but the implementation is my own.
