/etc/hostconfig is where OS X gets the hostname of the machine from. Change the line that reads:

HOSTNAME=-AUTOMATIC-

to:

HOSTNAME=trillian

Change trillian in the above line to whatever you want your machine to be called. Aparently there is a demon that you can restart for this change to take effect, but I dont know what it is so a restart is required.

If you need to check the ram on your machine and you happen to be running gentoo:

pddb-a01 linux # emerge -p memtest86

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] sys-apps/memtest86-3.0-r1

and then add this to grub.conf:

title=memtest
kernel (hd0,0)/memtest86/memtest.bin

Reboot and the choose the memtest option.

Found this (Broken link http://icu.unizh.ch/~dkocher/cyberduck/) cool ftp/sftp client for OS X, tis GPL too.

finally! there is a nice GPL virtual desktop ute, here

This one is very nice, a simpler one can be found here (Broken link ~~http://mediagods.com/tools/color_helper.html~~). This (Broken link http://mediagods.com/tools/rgb2hex.html) is a simple RGB to hex converter and finally there are some (Broken link http://mediagods.com/tools/) usefull other tools on MediaGods.com (Broken link http://mediagods.com/)

Just found this cool tool while looking for ip calculators, also has a cgi (Broken link http://jodies.cx/ipcalc_cgi) wrapper. Home page here

Just recently needed to tell Linux (2.4.18 on redHat 7.1SBE) to rescan the scsi buss for recently added luns, after looking around I’ve found this (Broken link http://www.garloff.de/kurt/linux/scsidev/) useful page with this (Broken link http://www.garloff.de/kurt/linux/rescan-scsi-bus.sh) handy little script which did the trick.

I’ve just recently bought one of these, I primarily bought it so i didnt need to run an extra piece of ethernet to the Xbox. It works perfectly, just tell it what SSID it should join and what your WEP settings are and plug it in. It works seamlessly with any ethernet device which is already configured for your lan. Brilliant.

Just recently I have been trying to get SMP + Hyper-Threading enabled on our 2650, this has caused me no end of grief. I have finally managed to get a working (and stable!) kernel compiled. The version I am using is 2.4.22 from the vanila-sources, which is the same as 2.4.22 downloaded from kernel.org (or a mirror)

The .config file for my working kernel is here, although the important bits are:

• CONFIG_SMP=y
• CONFIG_ACPI=y
• CONFIG_ACPI_HT_ONLY=y
• CONFIG_RTC=y

When this is booted with the extra command line arguments acpi=ht HT works. Now i wonder if HT actually makes that much difference!

Toby (Broken link http://www.bryans.org/toby/) has sent over a nice page over at IBM about Hyper Threading in Linux

I’ve had a problem with a gentoo machine not being able to find /dev/sdaX during the fsck portion of the boot process, after much arsing around I’ve tracked it down and fixed it. Details can be found here
