My submissions this year were quite limited: One Photo that didn't make it through the preselection and one effect for the Never-Demo (which made place 28 out of 29, n0y asked at a very late time "hey, can you code us some effect, the interface is really simple?", so I did some ascii-art-shading).<br /> ><br /> >I didn't manage to visit all seminars I wanted to see, I hope they'll get the recordings up soon.<br /> ><br /> >One I find worth mentioning:<br /> >Peci from Scoopex managed to get a dos-COM-file running windows-code without any win32/PE-headers (smaller, good for 4k intros). What he's doing is basically abusing an api for attaching drivers to the DOS-Emulation (VDD). It is able to call initialization-functions of DLLs from within DOS with invalid Opcodes. Calling it without initializing a library causes to jump to position 0. The memory from the DOS-process is mapped 1:1, so this is a valid adress, where you can put a jmp in the COM-file before calling.

You don't need to do anything further, just install it and run<br /> ><i>hddtemp /dev/hda</i><br /> >(Assuming your harddisk is hda, which is usually the case)<br /> ><br /> >It supports a bunch of harddisks by default and if it doesn't know your HD, it tries to access it with some default-values. Extending the hd-database seems to be trivial, I already sent a patch for my HD. Output looks like this:<br /> ><i>/dev/hda: SAMSUNG MP0804H: 46°C</i><br /> ><br /> ><b>lm_sensors</b><br /> ><br /> ><a href="http://netroedge.com/~lm78/">lm_sensors</a> is a bunch of drivers and tools to use hardware-sensors on motherboards. As you probably have no idea what chips your motherboard has, lm_sensors brings a tool called sensors-detect to help you. The way to go is just enabling everything (except debugging, which you usually don't need) in the kernel-sections i2c and hardware monitoring as module and let sensors-detect to the work.<br /> >Basically, pressing return all the time should be okay. At the end, it'll tell you which kernel-modules are useful for your system.<br /> ><br /> >After that, running sensors shows something like this:<br /> ><i>max6657-i2c-0-4c<br /> >Adapter: SMBus I801 adapter at 1100<br /> ><br /> >M/B Temp: +40°C (low = -65°C, high = +127°C)<br /> >CPU Temp: +36.6°C (low = +35.1°C, high = +72.2°C)<br /> >M/B Crit: +110°C (hyst = +100°C)<br /> >CPU Crit: +110°C (hyst = +100°C)</i><br /> ><br /> >Well, not that useful, but interesting to know that I have at least 3 temperature-sensors in my laptop.<br /> ><br /> ><b>Update:</b> As noted by Joshua Jackson in the comments, with <b>smartctl /dev/hda</b> (from <a href="http://smartmontools.sourceforge.net/">smartmontools</a>) you get the temperature and much more information about your HD. > </content:encoded> > > <pubDate>Thu, 23 Mar 2006 15:11:44 +0100</pubDate> > <guid isPermaLink="false">http://www.hboeck.de/item/303</guid> > <creativeCommons:license>http://creativecommons.org/licenses/by-sa/2.5/</creativeCommons:license><category>hardware</category> ><category>hddtemp</category> ><category>linux</category> ><category>lm_sensors</category> > ></item> ><item> > <title>Reverse engineering onlinetvrecorder</title> > <link>http://www.hboeck.de/item/296</link> > <category>Computer culture</category> > <category>Linux</category> > <category>Cryptography</category> > <category>English</category> > > <comments>http://www.hboeck.de/item/296#comments</comments> > <wfw:comment>http://www.hboeck.de/wfwcomment.php?cid=296</wfw:comment> > > <slash:comments>4294967294</slash:comments> > <wfw:commentRss>http://www.hboeck.de/rss.php?version=2.0&type=comments&cid=296</wfw:commentRss> > > > <author>nospam@example.com (Hanno Böck)</author> > <content:encoded> > <a href="http://www.onlinetvrecorder.com/">onlinetvrecorder</a>, a service that let's you record broadcasts from some german television stations, provides it's files in .otrkey-format, which can be decoded using their binary otrdecoder-tool, considering you have requested the recording in advance.<br /> ><br /> >As there is no information how the format and authentication work, I had a deeper look at it.<br /> ><br /> ><b>Getting the key</b><br /> ><br /> >Using some network sniffer, the authentication is very simple, it just requests them with http, the URL is<br /> >http://www.onlinetvrecorder.com/uncrypt.php?email=[email]&amp;pass=[pass]&amp;filename=[file]<br /> >(filename is the .wmv-name without otrkey)<br /> >Inside that file is an ascii/hex-encoded number with 128 bit. That very much looks like a key.<br /> ><br /> >This already gives us the possibility to manually download the key and, if we want to re-decode some movie (because we lost the wmv or because we want to decode a file before it's completely downloaded to already start watching the recording), save the key to a local webserver as uncrypt.php, forward the hostname to 127.0.0.1 and re-start otrdecoder.<br /> ><br /> ><b>The cryptography</b><br /> ><br /> >From what I found out yet, the file is encrypted with some sort of blowfish. The encrypted and decrypted files are exactly the same size, that means we have no IV and a variant of blowfish that does no padding.<br /> ><br /> >The best I got till now was using mcrypt with ecb-mode:<br /> >mcrypt -d -a blowfish-compat -s 16 -o hex -b --noiv -m ecb --nodelete -f [keyfile] [file]<br /> ><br /> >This decrypts the first 256 bytes correctly, after that it seems to mix up things (the correct decryption continues at byte 512). From what I read in Schneier[1996] (»Applied cryptography«), there is an ecb variant using ciphertex stealing that avoids padding.

I already knew this talk, so it wasn't so interesting. I also think there weren't much people in the room that had to be persuaded to resist software patents, so they should have probably choosen a more »visionary« topic for RMS to talk about. After that an interesting talk about the GPL v3 (also by RMS). I asked a question about the problem that GPL v2 only code can't be mixed with GPL v3 code, he asked me to email discuss this with him, what I will do.<br /> ><br /> >There were two talks about Xgl, one from Matthias Hopf telling what xgl is, what problems they face and some compiz presentation (with the always-known whooo-effect). Zack Rusin did a »Why Xgl is not the answer« talk. Was very interesting to hear the pros and cons of Xgl, I don't have a real opinion on that (I don't feel that I understand the technical details enough), but we should probably have an eye on the different futures X has (Xgl and aiglx at the moment).<br /> ><br /> >Another very interesting talk in the X room: Stephane Marchesin is working on reverse-engineering nvidia chipsets and intends to write a free driver for them. It's in a very early stage (basically at the moment just finding out how the chips work), let's wish him all success (see <a href="http://nouveau.sf.net/">nouveau - his not yet working first sources</a>).<br /> ><br /> >Suse gave out free (as in beer) t-shirts, so don't be amazed if you see me with a suse t-shirt running around <img src="http://www.hboeck.de/templates/hanno/img/emoticons/wink.png" alt=";-)" style="display: inline; vertical-align: bottom;" class="emoticon" /><br /> ><br /> >Some other more or less interesting talks, overall the presentations are the highlights of fosdem, you'll probably hardly find another event with so many interesting, high level talks about open source and free software.<br /> ><br /> ><a href="http://pictures.hboeck.de/v/fosdem2006/">Pictures will be here</a> as soon as I find time to upload them. > </content:encoded> > > <pubDate>Mon, 27 Feb 2006 22:59:57 +0100</pubDate> > <guid isPermaLink="false">http://www.hboeck.de/item/293</guid> > <creativeCommons:license>http://creativecommons.org/licenses/by-sa/2.5/</creativeCommons:license> ></item> ><item> > <title>FOSDEM trip</title> > <link>http://www.hboeck.de/item/292</link> > <category>Linux</category> > <category>Life</category> > <category>Gentoo</category> > <category>English</category> > > <comments>http://www.hboeck.de/item/292#comments</comments> > <wfw:comment>http://www.hboeck.de/wfwcomment.php?cid=292</wfw:comment> > > <slash:comments>0</slash:comments> > <wfw:commentRss>http://www.hboeck.de/rss.php?version=2.0&type=comments&cid=292</wfw:commentRss> > > > <author>nospam@example.com (Hanno Böck)</author> > <content:encoded> > <a href="http://www.fosdem.org/"><img width='270' height='80' style="float: right; border: 0px; padding-left: 5px; padding-right: 5px;" src="http://www.hboeck.de/uploads/fosdem.png" alt="FOSDEM" /></a>FOSDEM, the Free and Open source Software Developers' European MeetingFOSDEM, the Free and Open source Software Developers' European Meeting, will start on saturday.

As my cups was configured, I could select my printer, go to it's options and found a 4 pages on 1 option, so it seemed fine. Clicked on Print. Waited. Waited. Nothing happened.<br /> >Webbrowser, localhost:631, no printing jobs. No errors. Nothing.<br /> ><br /> >Looked at the logfile (this is at least the point where every common user wouldn't come further). Nothing that helped, just a note to change loglevel to debug. Did that. Restarted cups. Re-sent page. Logfile showed up some segfault in a gs-command. Damn, why can't just the interface tell me that?<br /> >From the small knowledge I have about linux-printing, I knew that there are various implementations of ghostscript. Looked into portage, found three, replaced ghostscript-esp with ghostscript-afpl. Restarted cups.<br /> ><br /> >Tried to print, my printer actually did something. Well, it looked interesting. I had the third page in the upper left corner and about a third of the fourth page beside it. Beside that, far smaller than it should be, nearly unreadable.<br /> ><br /> >Ok, there are some other pdf-viewers out there. Tried kghostview. Print, select 4 pages option, etc. Printer started doing something.<br /> >The result was really interesting: The pages were printed white on white.<br /> ><br /> >Next try, evince. As evince is a pretty new gnome-tool, it sticks to the gnome guidelines: Less config-dialogs, less features. It just had no possibility to print four pages on one. Oh, should I mention that evince crashed when I wanted to close the printing dialog?<br /> >Gave up. Will read it on the screen.<br /> ><br /> >Conclusion: Free software had some great success in the last years. Today we have systems that can compete to commercial ones in many areas for common usage. Some areas on the other side are really horrible. Printing is one of them.<br /> >If we really want to compete on the desktop, we need to get such basic tasks to »just work«. > </content:encoded> > > <pubDate>Wed, 15 Feb 2006 22:19:39 +0100</pubDate> > <guid isPermaLink="false">http://www.hboeck.de/item/287</guid> > <creativeCommons:license>http://creativecommons.org/licenses/by-sa/2.5/</creativeCommons:license> ></item> ><item> > <title>amaroK 1.4 with moodbar</title> > <link>http://www.hboeck.de/item/286</link> > <category>Computer culture</category> > <category>Linux</category> > <category>Music</category> > <category>Gentoo</category> > <category>English</category> > > <comments>http://www.hboeck.de/item/286#comments</comments> > <wfw:comment>http://www.hboeck.de/wfwcomment.php?cid=286</wfw:comment> > > <slash:comments>9</slash:comments> > <wfw:commentRss>http://www.hboeck.de/rss.php?version=2.0&type=comments&cid=286</wfw:commentRss> > > > <author>nospam@example.com (Hanno Böck)</author> > <content:encoded> > <a href='http://www.hboeck.de/uploads/amarok-moodbar.jpg'><img width='300' height='188' style="float: right; border: 0px; padding: 5px;" src="http://www.hboeck.de/uploads/amarok-moodbar.serendipityThumb.jpg" alt="" /></a>The greatest music player of all time, called <a href="http://amarok.kde.org/">amaroK</a>, just had the first beta release of the upcoming version 1.4.<br /> >The most visible new feature is the so-called moodbar that tries to color the »mood« of a track.
