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

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

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…

toStr revisited
After my initial toStr C++ exploration, I recent found myself reading about Boost’s lexical_cast, which is does something similar, albeit more general and with more verbosity. lexical_cast will not only convert nearly anything to a string, it will also do its best to convert anything to anything, via a string in the middle. Upon finding…

Zones on a single server
A few months ago my co-located Solaris server was hit by a root kit that setup a IRC bot. It appeared that it got it by attacking one of the off the shelf web apps I use. To prevent having to do a complete rebuild in the future if this happens again, I decided to…
