TP-Link TL-WR743ND is the PoE brother of the common TL-WR741ND wireless router which is supported flawlessly by openwrt. Since I’ve got one WR743ND, I wanted to convert it into a useful OpenWRT router but I figured out that, unfortunately, the WR743ND is not supported by OpenWRT (at least officially)
CadSoft’s Eagle (a well known CAD tool for designing PCBs) is not compatible as-is with Linux 64 bit. In my case, after a fresh Fedora 14 install, I was getting this error: # sh eagle-lin-5.10.0.run eagle-lin-5.10.0.run: /tmp/eagle-setup.3778/eagle-5.10.0/bin/eagle:
Today I’ve discovered that the very common Symbios 22801 (aka Symbios Logic 53c875) SCSI controller is (unexpectedly) failing to be recognized by Solaris 10 on x64 hardware. In fact I was in the middle of the upgrade of my home backup infrastructure from an old DLT 20/40 to

Using GNU Octave is easy to plot Bode and Nyquist diagrams, as follows: bode(zp([], [-1*i, i, -1], 1)) nyquist(zp([-0.5], [0.0, -0.2, -4], 1))

Mount a samba share on the fly without having it mounted statically at boot via the /etc/fstab file can bring you the advantage of a painless boot in case of unavailability of the samba server like in the following common scenarios: * laptop: you mount your pc share at home,
