This past weekend I flashed my Openmoko Neo Freerunner to the software distribution known as SHR. Immediately I was very pleased with the look, and after playing with it most of the weekend, I’m now attempting to use it as my primary phone.

GPRS was working, but I wasn’t satisfied with any of the current graphical tools to launch it, of which I only knew of one, and launching at the command line is unacceptable, as things on a handheld device need to be finger-friendly.

With that in mind I wrote a small graphical utility to launch GPRS on FSO based distributions. The tool makes use of Gtkdialog, which wasn’t in the SHR repositories, so I had to build the ipk as well: gtkdialog-0.7.9_0.1_armv4t.ipk.

At one point I had 4 different applications accessing the Internet at once: a browser surfing the web, an active chat via Pidgin, a terminal with an SSH session to a remote host, and tangoGPS downloading map tiles. Granted, none of it was super fast; GPRS is old, slow technology, but it’s still usable for many things. And over all that I was still able to receive a phone call. Things are getting better by the day for Openmoko Neo owners, but there is still a way to go.

Today I was in need of pre-allocating a 50G file on a number of CC‘s servers. I started off with this:

# dd if=/dev/zero of=bigfile.bin bs=1M count=50000

However, that operation was too expensive in terms of disk I/O and was causing critical web services to fail. I played around with multiple options in dd but to no avail. I finally ended up doing this, which works, but seems rather ridiculous. Surely there’s a better way to do it:

# for i in $(seq 1 50000); do nice -n 19 dd if=/dev/zero of=bigfile.bin conv=notrunc oflag=append bs=1M count=1 &> /dev/null && sleep 0.1; done

The nice probably isn’t necessary, but I threw it in for good measure.

Sometime back in 2002 I started writing a nutrition database in PHP that was based on data from the USDA Nutrient Data Laboratory. In 2003 I left the U.S. for a Peace Corps assignment in Belize, then stayed in Central America for about another year and half before returning to the States. When I came back I rewrote the whole thing and registered the domain nutridb.org. It doesn’t really get used, but the code is there under an MIT (X11) license.

Below is the bit of javascript that handles the text transitioning at the above URL. More than anything this was a way for me to explore the use of setInterval(), a javascript builtin function which I didn’t previously know about.

setInterval('lolme()', 1000);
i = 0;
function lolme() {
	var ar_lol = new Array(
		"nath@nkinka.de?",
		"lol",
		"rofl",
		"omg wtf bbq",
		":-)",
		";-)"
	);
	var ar_cnt = ar_lol.length;
	(i == 0) ? pi = ar_cnt - 1 : pi = i - 1;
	var loldiv = document.getElementById('lol');
	if ( loldiv.childNodes[0] ) {
		loldiv.removeChild(loldiv.childNodes[0]);
	}
	loldiv.appendChild(document.createTextNode(ar_lol[i]));
	(i == ar_cnt - 1) ? i = 0 : i++;
}
