Just a quick announce: We released libsigrokdecode 0.1.1 today, a new version of one of the shared libraries part of the open-source sigrok project (for signal acquisition/analysis of various test&measurement gear, like logic analyzers, scopes, multimeters, etc). I will update the Debian package soonish.
As you probably know, in addition to the infrastructure for protocol decoding, this library also ships with a bunch of protocol decoders written in Python. Currently we support 29 different ones (in various states of "completeness", improvements are ongoing).
Happy hacking and decoding!
I have no idea how such a great open-source game as Teeworlds has been able to exist without me hearing about it until recently.
Teeworlds is a fast-paced realtime multiplayer shooter. You control a small "Tee" which can hold various weapons (hammer, gun, shotgun, laser-rifle, rocket launcher, ninja-sword) while running and jumping around frantically on the map, trying to frag as many other Tees as you can before you're killed by some other guy. Easy, eh?
There's are many game servers to choose from, as well as various game modes (death match, team death match, capfure the flag and some unofficial "mods"). You can join servers on the Internet, or create your own server, be it a public one or a LAN server.
Usually I would suggest apt-get install teeworlds, but for now the packages in unstable are an older 0.4.x version, whereas upstream released a much-improved 0.5.1 version. I have already filed a bug and I'm optimistic there'll be a new version in unstable soon.
In the mean-time however, you can manually build the game from source via:
$ apt-get install zlib-dev libsdl1.2-dev (maybe also libgl, libglu, and python, if not already installed) $ wget 'http://teeworlds.com/trac/bam/browser/releases/bam-0.2.0.zip?format=raw' -O bam-0.2.0.zip $ wget http://teeworlds.com/files/teeworlds-0.5.1-src.zip $ unzip bam-0.2.0.zip $ unzip teeworlds-0.5.1-src.zip $ cd bam-0.2.0 $ ./make_unix.sh $ cd ../teeworlds-0.5.1-src $ ../bam-0.2.0/src/bam release
You'll obviously need a working OpenGL/DRI setup (check if "glxinfo | grep direct" says "Yes"), otherwise the game will be way too slow. In case you experience graphics glitches and distortions, first exit the game, then:
$ vi ~/.teeworlds/settings.cfg
Change the "gfx_noclip 0" option there to "gfx_noclip 1" and restart the game.
If you use a local firewall as I do, you need to open at least ports 8300-8303 (UDP), even better 8300-8310 for more choice in game servers:
$ iptables -A OUTPUT -m state --state NEW -p udp --dport 8300:8310 -j ACCEPT
Here's a nice opportunity for everyone to learn more about coreboot, a Free Software / Open Source firmware/BIOS for x86 PCs.
Ron Minnich, founder of the LinuxBIOS (now called coreboot) project, Peter Stuge of Stuge Konsult, and Stefan Reinauer of coresystems GmbH have given a presentation for the Google Tech Talks series recently. The topic was (of course) coreboot, its history, goals, features and technical details, surrounding tools and libraries such as flashrom and libpayload, as well as an automated test system for running a hardware test-suite upon every checkin in the coreboot repository.
A video of the talk, aptly named coreboot (aka LinuxBIOS): The Free/Open-Source x86 Firmware (134 MB), is available from Youtube, get it for instance via:
$ apt-get install youtube-dl $ youtube-dl http://www.youtube.com/watch?v=X72LgcMpM9k
The talk includes various demos of coreboot and various payloads you can use with coreboot. One nice example is the TINT payload, a Tetris-like game for Linux (
apt-get install tint for the curious), which has been reworked to be usable as a coreboot payload.
So, yes, you can now put Tetris in your BIOS ROM chip and play it from there (no hard drive required).
Other demos included some cluster nodes with coreboot, and a "normal" x86 desktop board booting coreboot + Linux in a very few seconds (much room left for optimizing there though, if you really want to get into fast booting).
Check out the full talk for more infos, and if you're willing to give it a try (see the list of currently supported boards), contact us on the mailing list or join the #coreboot IRC channel on Freenode.
Today seems to be Firefox/Iceweasel 3 Bashing Day on Planet Debian, so let me join the fun :)
I agree with most other people that the default Firefox/Iceweasel 3 config is not ideal, so here's what I did to fix it. Some of these items improve performance, some remove annoyances, some remove privacy issues, some remove security issues. Not everything here may be desirable for people other than me.
Select "Edit / Preferences".
Open a new tab, enter "about:config" as URL and hit ENTER. Click the annoying "I'll be careful, I promise!" button. Uncheck "Show this warning next time" while we're at it.
browser.urlbar.matchOnlyTyped = trueto disable the new, annoying "AwesomeBar" URL bar feature (which is also a huge privacy risk).
browser.tabs.tabMinWidth = 60and
browser.tabs.tabMaxWidth = 60(needs a browser restart). You can even use less than
60if you don't need any text and an icon per tab is enough for you.
extentions.getAddons.showPane = false.
bidi.support = 0. You'll probably never need it, so reduce the number of potential bugs and security issues by disabling it.
browser.ssl_override_behavior = 2and
browser.xul.error_pages.expert_bad_cert = true(thanks Pierre Habouzit).
browser.tabs.closeButtons = 3in order to prevent accidental closing of tabs (no more Close buttons on each tab, only one global Close button on the right). Yes,
CTRL+Shift+Thelps in case it still happens.
network.prefetch-next = falseto prevent random prefetching of webpages which means wasting CPU cycles and bandwidth, as well as subtle privacy and security issues.
None. Don't even think about installing crap like the closed-source Flash player if stability or security are important to you. If you absolutely must watch YouTube videos, I recommend youtube-dl.
Use as few as possible. Every extention may have security problems or bugs, and can negatively affect performance etc.
