Eken M001, Android Tablet
I recently purchased an Eken M001, one of the cheap android tablets that you can find on eBay. There are a lot of the super cheap tablets using Via WonderMedia chips. Based on online specs, the biggest differentiator between different models is whether it has 128 or 256 megs of RAM. It is possible that…

Handy emacs printing trick
emacs -nw myfile.c -e “ps-print-buffer” -e “save-buffers-kill-terminal” By extension, you can keep stacking -e’s with interactive functions that take no arguments for as many commands as you want. I would imagine there is a way to pass arguments to the functions you list, but I haven’t found that yet. Also, it might be nice to…

A new thermometer
I don’t know where I got the idea from, but I’ve long thought that knowing how hot a pan is would be tremendously handy. And of course, the obvious way to measure surface temperature is with an infrared thermometer. So, I went and got a Ryobi IR001 Non-contact Infrared Thermometer (with Laser) from Amazon (see…

Circular buffers as C Macros
I was recently reviewing some FIFO based serial TX/RX circular buffer code that I thought was buggy in the FIFO part. Since the FIFO was entwined with the ISRs, it was hard to test in isolation. I looked around at some other FIFO implementations for PIC and AVR, and all of them did the same thing, including…

Using rxvt with [Open]Solaris.
After years of hard coding TERM to xterm or vt100 in .bashrc to get around rxvt incompatibility, I finally found this: sudo cp /usr/gnu/lib/terminfo/r/rxvt /usr/share/lib/terminfo/r/rxvt I suppose I really should use pfexec instead of sudo, but mastering that is a job for another month.

XO Update: F11 based image
This past weekend I updated to the new XO-1 firmware image following the directions at this website. The process was simple and painless. I believe this was the first significant update since Sugar was spun off from the OLPC project, and I had long given up hope of seeing any significant updates for the XO-1.…
