Starting the IPv6 revolution

I'm in the progress of setting up working IPv6 on all computers I have access to. I'm fed up with all the hacks needed for properly accessing devices remotely.

Google Apps Script for SMS notifications and more

I've recently learned that the Google platform enables you to connect various services via server side ECMAScript . I've encountered a nice example which sends out a notification for each e-mail that your filters tag as urgent. I've altered a lot of its functionalities, and now it supports the following: Concatenates the subject and the body Jams the first 60 characters in the title, the next 63 characters in the location Preprocess automated mails to only keep the most important fields (RegExp does wonders) Extract and aggregate various daily indices of interest (UrlFetchApp is also nice) As an exception to my usual philosophy, I will have to give second thought if I should be sharing these enhancements or not this time.

Reverting from BTRFS to Ext4

I had to revert from compressed BTRFS to Ext4 on my tiny netbook partition, as it wasn't playing nice. That's a pity, as Ubuntu is highly compressible and compression didn't slow it down. The system occupied less than half of the space and reported such, however when I was starting to fill up the space, it complained of insufficient space. Probably because of metadata allocation. As I didn't want to reinstall the system, I went the more costly route: * I've rebuilt the partition in an image on ext4, * copied over the data * copied the initrd image from another computer of mine with the exact same system, both were updated at the same time - otherwise it couldn't read the new kind of partition * adjusted grub settings * reinstalled grub (was extra painful when I attempted to do that inside an image..).

Ubuntu 11.04 vs. Intel 865G

Hm, it looks like this post has stuck in my drafts for some years now... Compositing produces a considerable amount of flicker and the display is obstructed by random image parts. dmesg is also full of page flip errors. Solution: cat >~/.drirc <<EOF <driconf> <device screen="0" driver="dri2"> <application name="Default"> <option name="vblank_mode" value="0" /> </application> </device> </driconf> EOF service gdm restart via https://bugs.freedesktop.org/show_bug.cgi?id=30654#c10 and http://pastebin.com/3gr5VbHY Also needed to append the following to the kernel command line, or else I got a lot of squashfs block read errors: acpi=off noapic ide=nodma all_generic_ide pci=nommconf

Watching 3D TV for free using mplayer

Antenna Hungaria is testing 3D broadcast over the air for the time of the Summer Olympics and the UEFA European Football Championship . In idle time, they are scheduling lovely programs of documentary, nature and the like. Anyway, I wanted to see how easy it is to view such side-by-side content in 2D while preserving maximal quality. As anticipated, mplayer works like a charm, see the uploaded script: watch_3d_dvb.sh

PCI DVB tuner fix for timeout waiting for DSP ready

I had a similar problem as described below on Ubuntu 12.04 and found that inserting saa7134-dvb into /etc/modules.conf did the trick for me too. It's interesting though that it has been working fine before. I did recall seeing this issue once or twice, but this time it did not seem to have been resolved by multiple cold booting by itself. http://linuxtv.org/pipermail/linux-dvb/2008-June/026775.html [ 43.162971] tda1004x: timeout waiting for DSP ready [ 43.202914] tda1004x: found firmware revision 0 -- invalid [ 43.202918] tda1004x: waiting for firmware upload...
