The talk will discuss how ICT can be used to reduce greenhouse gas emissions 15% by 2020. Also outlined is how to use the web for running formal, university accredited courses using free open source software with open access content delivered to smartphones. The Istanbul public transport system also gets a mention. ;-) See Tom's Web site[4] for more information. Tom runs green IT courses at ANU and ACS. You can read the free open access version here.

[SLUG] Hanging /or random reboot probs
Hi, I have just installed lenny on a machine with 800MHz AMD Duron chip, 1Gb RAM, 63.3 GbB /usr, 320Gb /home yet get hanging and/or rebooting after opening applications in two screens (usually update/upgrade as root and mutt or a browser). My previous etch system with 733 MHz PIII and 733 Mhz RAM could handle 10 or more screens running various apps at a time. Any ideas about what I should be looking for ?

Re: [SLUG] Hanging /or random reboot probs
Sounds like bad memory. Replace memory or pull out all memory chips bar one if possible. See if you can isolate which chip it is. I've had this before.

Adam Bogacki, a...@paradise.net.nz Hanging and spontaneous reboots are classic symptoms of memory failure. Does Debian offer you a boot option to boot into memtest? If so, I'd recommend running it, with one dimm in the machine at a time until you isolate which one(s) is faulty. Happy Hunting.

[SLUG] kernel oops help
Hi Folks, I just had a whole bunch of kernel oopses on my laptop. I'm running Debian 5.0; kernel is 2.6.26-2-686 I get a dialogue in gnome telling me my kernel has just failed and lines in /var/log/messages like: kerneloops: Submitted 2 kernel oopses to www.kerneloops.org Everything appears to be working though. Just before the oops entries in /var/log/messages, I have ata1: hard resetting link a line after this printing out all my linked in modules Modules linked in: ... alot ... and then what looks like some debug info: Pid: 14285, comm: top Not tainted (2.6.26-2-686 #1) EIP: 0073:[b7de108c] EFLAGS: 0216 CPU: 0 [ ... several more lines of debug guff ...] Is this an impending disk failure, power problem or have I been pwned? :( -- Daniel Bush -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] White noise at the end of a WAV file that only Audacity can't see
I am trying to re-encode some music files from Apple Lossless to FLAC[1] and there is a very short burst of white noise at the end of the file that every music player *except* Audacity can see. Here's what I am doing. 1. Convert the ALAC music files to WAV (I was originally going straight to FLAC, but tried to cut some steps out in order to figure out which step in the chain was producing the white noise). Either of these tools produce the same effect: alac-decoder -f output.wav input.m4a ffmpeg -i input.m4a output.wav 2. Listen to the WAV files using any of the following tools: - totem - Squeezebox/Squeezecenter - Rhythmbox All of them render about 1/4 second or so of white noise at the very end of the playback. Further, this is preserved by flac when I convert the WAV file to FLAC. 3. Think oh well, I guess I can edit the white noise off with Audacity! Open WAV file in Audacity, discover that the white noise is not there in Audacity (not in the waveform, not present when I use Audacity itself to play it back) 4. Think oh well, it's the least automatable setup ever, but if Audacity doesn't render the white noise, I can at least use it to export to FLAC! Do so, and discover that the resulting FLAC files still have the white noise at the end when played in totem/Squeezecenter/Rhythmbox. I've also had a friend with Apple hardware (an iPod) play the original ALAC files and he reports that they do not contain a burst of white noise at the end. So I am out of ideas: does anyone know what the white noise is, why Audacity can't see it and thus let me edit it off but still renders it, or any tools that will allow me to produce FLAC files without a very annoying burst of static at the end? -Mary [1] I have Apple Lossless files because that's the only lossless format that The Dandy Warhols are selling The Dandy Warhols Are Sound in. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Open WAV file in Audacity, discover that the white noise is not there in Audacity (not in the waveform, not present when I use Audacity itself to play it back) Ah, it is there, but it's extremely short, much shorter than played by the other players. So presumably this is a problem with the ALAC decoders. -Mary -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Further, this is preserved by flac when I convert the WAV file to FLAC. Most audio files have a header which contains file metadata like sample rate, number of channels etc. WAV (and AIFF among others) also allow metadata to be placed at the end of the file (I think its was a huge mistake to allow this). I suspect that totem and the others are incorrectly treating this end-of-file metadata as audio data. Audacity (which uses libsndfile) however does the right thing and displays only the audio data. It you post the output of: sndfile-info filename I can confirm this. sndfile-info is in the sndfile-programs package in Debian derived distros. So I am out of ideas: does anyone know what the white noise is, why Audacity can't see it and thus let me edit it off but still renders it, or any tools that will allow me to produce FLAC files without a very annoying burst of static at the end? Recent versions of sndfile-convert (= 1.0.18 I think) will correctly read the WAV file and create a flac file by doing: sndfile-convert a.wav a.flac.

LCA2010 will be held from Monday 18 January 2010 to Saturday 23 January 2010 in Wellington, New Zealand. linux.conf.au isn't just a Linux conference. It is a technical conference about Free and Open Source Software, held annually in Australasia since 2001 - covering everything from the Linux Kernel and the BSDs to OpenOffice.org, from networking to audio-visual magic, from hardware hacks to Creative Commons. === Important Dates === Call for Papers opens: Monday 29 June 2009 Call for Papers closes: Friday 24 July 2009 Email Notifications from Papers Committee: Early September 2009 Registrations open: Mid September 2009 Conference Dates: Monday 18 January to Saturday 23 January 2010 === Information on Papers === The LCA2010 Papers Committee is looking for a broad range of papers spanning everything from programming and software to desktop and userspace to community, government and education but there is one essential: The core of your paper must relate to open source in some way, i.e., if it's a paper about software then the software has to be licensed under an Open Source license. The LCA2010 Papers Committee welcome proposals for Papers on the following topics: * Kernel and system topics such as filesystems and embedded devices * Networking topics such as peer to peer networking, or tuning a TCP/IP stack * Desktop topics such as office and productivity applications, mobile devices, peripherals, crypto security and viruses and other malware * Server topics such as clusters and other supercomputers, databases and grid computing * Systems administration topics such as maintaining large numbers of machines and disaster recovery * Programming topics such as software engineering practices and test driven development * Free Software and Free Culture topics, including licencing and Free and Open approaches outside software * Free Software usage topics, including home, IT, education, manufacturing, research and government usage. Most presentations and tutorials will be technical in nature, but proposals for presentations on other aspects of Free Software and Free Culture, such as educational and cultural aspects are welcome. LCA2010 is pleased to invite proposals for three types of papers: * Presentation - 45 minutes * Tutorials - 1 hour and 45 minutes (short) * Tutorials - 3 hours and 30 minutes (long) Presentations are 45 minute slots (including questions) that are typically a one-way lecture from you to the audience - the typical conference presentation. These form the bulk of the available conference slots. Tutorials are either 1 hour and 45 minutes, or 3 hours and 30 minutes in length, and work best when they are interactive or hands-on in nature. Tutorials are expected to have a specific learning outcome for attendees. To increase the number of people that can view your talk, LCA2010 may video the talks and make them publicly available after LCA2010. When submitting your proposal you will be asked whether materials relating to your paper can be released under a Creative Commons ShareALike License.
