Why is writing a correct BIOS so hard?
Date: March 23rd, 2009 by SiD3WiNDR
Categories: Hardware

Wanted to install cpufreqd on my router box a few days back, noticed I needed a new kernel for that to work. There’s an E4400 Core2 Duo in there, supporting 2GHz, 1.8GHz, 1.6GHz and 1.2GHz. When I rebooted into the new kernel, I saw support for exactly half of those.. doh. As the module is acpi-cpufreq, the module uses the tables specified in the BIOS.

So I set out to upgrade it… having a nice PXE setup for booting floppy images over the network is nice and all, but doesn’t work if you’re upgrading the PXE server itself. Ended up wasting a CD for this as the floppy didn’t work (should have put music onto it as well, doh) … BIOS upgraded, but my ethernet card didn’t work anymore.. what the …

Had to add irqpoll to the kernelcommandline to get it to life again, but /proc/interrupts shows the following:

 48:          0          0   IO-APIC-fasteoi   eth2

16:      35052          0   IO-APIC-fasteoi   uhci_hcd:usb4
 

Except I don’t have anything USB connected and eth2 has my internet connection. Frakked up IRQ routing and nothing in the BIOS to change things… I’ll try swapping the slot later this week but I doubt this will help as it’s on an active risercard… 🙁

ISP Karting 2009
Date: March 22nd, 2009 by SiD3WiNDR

Had a lot of fun today, as after five years of "silence" someone took up the challenge of organising a new ISP Karting event . Infradata together with Juniper, MRV and Barracuda hosted half a day of fun & games at Inkart Puurs. Thanks to some sponsoring I got to enter as well, I’ll most likely be there next year as well, as they seem to be keen on organising it again 😀

What I got from my parents last weekend:

😀 (sorry for the crappy pic..)

Inside, just a regular "Belgian chocolate (!)" egg with some smaller chocolate cars 🙂 Oh, and it’s got a sound chip with roaring engines 🙂

Extracting a boot image from a CD

Just needed to extract a boot image from a CD, geteltorito works nicely (except it outputs to stdout, sigh 😉 )

Finetuning with MythTV
Date: March 16th, 2009 by SiD3WiNDR
Categories: MythTV

If you want to do some finetuning of your analog channel frequencies, MythTV doesn’t have a really handy interface for it, and you can’t immediately see the results of your actions. With this page (courtesy of my darling wife) you can enter the correct frequency of the channel (I extracted it from C:\Program Files\DScaler\program.txt 😉 ) and it’ll give you the correct MythTV channel name + optional finetune frequency.

Analog scanning and naming of channels on MythTV
Date: March 14th, 2009 by SiD3WiNDR
Categories: MythTV

After you’ve scanned your channels on your analog tuner (in my case, a PVR-500) you’re left with a bunch of unknown channel numbers. At first I started tuning in and jotting down what channel was what number, until my darling wife pointed me to a Telenet site, zenders.be , which has a nice channel mapping per postal code. Very handy 😉

A day of shopping
Date: March 7th, 2009 by SiD3WiNDR
Categories: Rants

To the engineer who made the shopping carts at Colruyt (Kessel-Lo):

DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE
DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE
DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE
DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE
DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE
DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE DIE

FYI: Shopping carts in Belgium are usually used in a forward pushing way, and not pulling it.
As such, you NEED to place the non-turning wheels in the correct position (at the rear) or even better, don’t have any at all!
Consequence of this great piece of engineering is everyone constantly cursing and ramming into people and store racks because the carts are mostly uncontrollable.

To the other shoppers: please have some common sense about where to place your cart when you’re not taking it along, or where to stand when letting someone pass.
To the store owners: don’t put sh*t like cardboard boxes and other stuff in the middle of the hallways if you know your store is overcrowded already. Also, redesign it so you actually have a clear way to the checkout instead of filling up 2/3 of the store with customers waiting in line.
To the motherfsckers cutting in line without any shame (nonsurprisingly most are 60+): I hope you die. Today.

(Yes, this was my last time ever entering that store).

This may sound harsh but I got really ticked off trying not to run away screaming today.

debmirror gnupg problem
Date: March 2nd, 2009 by SiD3WiNDR
Categories: Debian

Something seems to have changed in the debmirror prorgam on lenny:

gpgv: Signature made Sun Mar  1 16:27:33 2009 CET using DSA key ID 1F41B907
[GNUPG:] ERRSIG 07DC563D1F41B907 17 2 00 1235921253 9
[GNUPG:] NO_PUBKEY 07DC563D1F41B907
gpgv: Can’t check signature: public key not found

This error turned up when I tried to mirror debian-multimedia.org after upgrading debmirror. Apparently the new version looks for the keys in ~/.gnupg/trustedkeys.gpg. If you installed the debian-multimedia-keyring package, you can use the following:

 gpg –no-default-keyring -a –keyring /usr/share/keyrings/debian-multimedia-keyring.gpg –export 07DC563D1F41B907 | gpg –no-default-keyring –keyring ~/.gnupg/trustedkeys.gpg –import –

This imports the current key into the new file.
