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…

Small revisit of C++ message passing (in a threaded program)
The post C/C++ Message Passing from June ’08 is one or the more popular ones, if Google Analytics is to be believed. Not only that, but every one who arrived there by Google search was looking for C++, not C. Upon re-reading it, it occurs to me that it would be a good candidate for…

Oops
All the pictures in old entries are missing, and it seems that it is because a pictures folder was removed. Now looking for a backup. And this time perhaps I should let WordPress keep track of them instead of making my own image folder. And now it should be fixed, so please let me know…

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.

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.…

Intel D510MO Atom
I had a theory that the Intel D510 CPU would be good enough for several tasks, including Linux audio (Ardour, Bristol, PureData, etc), NAS device, and HTPC (home theater PC). Not at the same time though, of course. I bought one of the Intel D510MO boards from Logic Supply. This board isn’t going to be…

OpenSolaris on the Intel D510MO Atom
I wanted to tryOpenSolaris on the new Atom board on a seperate disk before the machine got settled into normal use (normal use covered in this post). First impression, the LiveCD booted and worked correctly including graphics in VESA mode and the networking. The install was simple and painless, and afterwards came right up with…
