Kleinere Neuigkeiten rund um Planet Symlink //at 00:04 //by abe

Aus der raus-und-rein Abteilung

Mal eine kleine Zusammenfassung der letzten Änderungen auf Planet Symlink:

Tobias “tuxedo” Klauser hat vor längerer Zeit mal ein Update der Planet-Software gemacht, was einige Probleme, vor allem mit Blogs in UTF-8 behoben hat.

Allerdings hat der Planet momentan (seither? schon immer?) den Bug, dass in der Sitebar die Links zu den Feeds zurück zum Planet zeigen. Werden wir uns noch näher anschauen und dann flicken. Update 00:37 Uhr: Tobias hat’s recht schnell gefunden und geflickt. URI ist nunmal ungleich URL, insbesondere in Variablennamen. :-)

Eventuell werden sich Tobias oder ich auch mal Planet Venus als mehr oder weniger kompatible Alternative zu Planet Planet anschauen. Mal sehen…

Dann gab’s eine ganze Ladung Abgänge und Neuzugänge, die noch nicht erwähnt wurden:

Abschusskandidaten. Auch die gibt es. Beim Hinzufügen von Blogs sehe ich immer, welche Blogs Fehler schmeissen. Einige davon sehen momentan nach permanenten Problemen aus. Die fliegen dann vermutlich demnächst irgendwann raus, falls es keine Änderung gibt…

  • blog.qolume.ch: Nameserver der Domain qolume.ch nicht erreichbar. Zitat aus #lugs: “Den qolume gibts eh nicht mehr.”
  • www.sunflyer.ch: Nameserver der Domain sunflyer.ch werden nicht gefunden, weder im DNS noch im Whois. Wusste gar nicht, dass sowas geht.

Problem ist einfach, dass man diese Leute ohne DNS auch schlecht kontaktieren kann oder auf deren Webseiten nach neuen URLs für Feeds suchen…

MicroClient Sr. //at 04:35 //by abe

from the *WANT* dept.

About a year ago, I bought a Norhtec MicroClient Jr., a complete 200 MHz MMX-compatible SoC (“Vortex86”) PC so small that it fits into your hand or onto VESA mountings. Althought thought as thin client, the machine has 128 MB RAM and runs Debian from either netboot, USB stick, CF card or 2.5” harddisk without problems and not even that slow.

Later last year, we needed more MicroClient Jrs. at work and since the MicroClient JrSX had a 300 MHz 486SX-compatible SoC processor (“Vortex86SX”) from MSTi and 128 MB DDR RAM instead of SD RAM, we expected them at least in the same performance range and bought a few for ETH and I also bought one for myself. Well, they were about three times slower, since the FPU is missing, not all programs from Debian Etch work fine, e.g. X doesn’t work without patching and recompiling (with Sid, X works, but not the kernel anymore – Update, 26-Jul-2008: See #454776 for a solution for this problem)…

BTW: I had both machines with me at FOSDEM ‘08 at the Debian booth and the MMX-compatible machine also at Chemnitzer Linux-Tage (CLT) at the Symlink booth and in Kurt Gramlich’s talk about ecological computers. So if you saw them there, just imagine the same case, with a twice to three times faster CPU and four times the amount of RAM, but with roughly the same carbon foot-print!

For our thin client purposes at work we now use ALIX boards from PC Engines (Mini-ITX format) with 500 MHz AMD Geode processors. They’re much faster than the MicroClient Jr. and need even less power.

Today, while surfing around on some Mini-ITX shops, I found some computer in obviously MicroClient Jr. case, but with 500 MHz VIA Eden processor and 512 MB of RAM. I first couldn’t believe it. They are selling it as eTC-2500. Since eTC-2300 was one of the brandings of the MicroClient Jr. which is called eBox-2300 officially by the manufacturer DM&P, I searched for eBox-2500, but didn’t find anything useful. Then I looked at the manufacturer’s product page at CompactPC.com.tw and found the eBox-4300 — so it’s really true, they managed to fit a board with 500 MHz VIA processor and half a Gig of RAM into the already fscking small space inside the MicroClient Jr. case, and even without needing more power: Still 15W from the power adaptor. Next stop was Norhtec’s Website. And yes, they also have a new MicroClient product: The MicroClient Sr.. I really need to have one of those for my MicroClient collection! ;-)

Axel’s Cruftiness Theorem //at 19:20 //by abe

from the my-systems-are-all-uncrufty dept.

Theorem: If aptitude is used, set to automatically remove unneeded packages and every not willingly installed package is marked auto, the system’s cruftiness is always 0.

First two weeks with the Brompton //at 03:08 //by abe

from the new-habits dept.

It’s here! In contrary to the estimated delivery time of about ten weeks, my Brompton arrived at Velofix at Saturday the 16th of February after only three weeks. The orange color is much nicer than the apple green I initially favourited from what I saw in the catalouge and the axle dynamo also proved to be a good idea, so I’m really happy about my choice.

I used the Brompton to go to work everyday the last two weeks, even when it’s snowing like today:

Snowy Brompton Snowy Brompton Folded Snowy Brompton

Although I’m starting slowly and taking the bus (hey, it’s a folding bike! :-) for the steepest parts (either from Am Börtli to Waidbadstrasse or Gsteigstrasse)… I even managed to fold the bike although I saw the bus already coming around the corner when I still was in the saddle. That was the day I was at work in less then 10 minutes — Perfect timing. :-)

Since the local Höngg bus (route 38) only makes it’s round every 30 minutes, with the bike I’m now much more flexible and don’t have to hurry in the morning to catch the bus. (OTOH I had to notice that “being more flexible” doesn’t mean “having more time”… :-)

I also use it on the campus for visits in other buildings. Although there are mostly stairs between the different levels of the campus, it’s no problem with the Brompton since it’s easy to carry, even if not folded. It’s much more comfortable than daduke’s little kickboard scooter whose hard wheels don’t feel healthy for bones and especially knees on ETH Hönggerberg’s paths made out of washed-out concrete. Air tyres and rear suspension are much better… :-)

Regarding the choice of gears: The MountainDrive would surely be helpful in hilly Zürich, especially since my fitness isn’t the best one at the moment, but 6 gears are ok, too, and will be even more ok as soon as my fitness gets better. The slower transmission wasn’t a bad choice either, although a wider transmission range would have been better.

Is ikiwiki a Website Meta Language killer? //at 22:29 //by abe

from the there-was-nothing-better-—-until-now dept.

On this year’s Chemitzer Linux-Tage (CLT, engl. “Chemnitz Linux Days’) I attended a few talks of which especially formorer’s ikiwiki talk was very interesting.

I attended his talk since I found out that ikiwiki is command line wiki compiler in contrary to the thousands of solely web based wikis out there. As a big fan of statically generated content this idea sounded very interesting to me.

But just having a short look at ikiwiki’s web page didn’t help to get started and it seemed as if I had not the right idea of how ikiwiki works to get started. So formorer’s talk seemed to be a good possibility to get an idea of how ikiwiki works without much effort.

During the talk I noticed that ikiwiki can many things I do with the Website Meta Language (WML), but can do some more things WML can’t do out of the box:

  1. It’s not only a framework to generate web pages, it’s more like a content management system (CMS).
  2. Versioning is intergal part of ikiwiki without reinventing the wheel: It works out of the box with — beyond others — Subversion, Git and Mercurical (Hg).

And when formorer showed that even Tobi Oetiker uses ikiwiki, I noticed that ikiwiki probably could be a WML killer, since I knew Tobi as a WML fan. And ikiwiki looks very appealing for the WML fan inside me, too…

OTOH: Intergrating WML as a backend to ikiwiki could be an interesting idea, though.

Hearing what kind of input files ikiwiki can process, I also got the idea of using hnb (Hierachical Notebook) files as input for ikiwiki. hnb files are already XML and so a conversion to XHTML shouldn’t be that hard.

But when searching the web for “ikiwiki hnb” I found the blog postings of a few people switching away from hnb, e.g. to vimoutliner. Since I’m an Emacs addict and don’t like vim very much (if I use a vi, I use nvi or elvis), I searched for “emacs hnb” and indeed found someone who switched from hnb to org-mode – of which I never heard before. Unfortunately org-mode doesn’t seem to be in Debian (Update 00:23: Yeah, yeah, I now know it’s included in emacs22, but emacs22 hasn’t made it into kfreebsd-i386 yet, so I didn’t notice. See the comments. :-) but I’ll play around with it a little bit. Unfortunately a first test wasn’t that promising. But we’ll see.

WTF per minutes and yet another popular Blosxom-alike I didn’t know about //at 02:42 //by abe

from the muse-of-many dept.

Today while reading Planet Webtuesday, I stumbled upon a nice cartoon about the one and only measurement of code quality: WTF per minute.

Somehow I noticed that the blog in which this cartoon was posted in is powered by Blojsom, a Blosxom derivative written in Java (and nowadays database powered). I already have heard of a lot of blogging software which works similar to Blosxom and often is also named similar, e.g. Pyblosxom or Blosxonomy, but Blosjom hasn’t been noticed by yet although it is mentioned in Children of Blosxom where I first noticed Blosxonomy.

So far, so good, but what really surprised me is that a blog engine developed after Blosxom’s ideas officially made into MacOS X 10.4 Server. (BTW at a time, I neither had a blog nor knew about Blosxom. :-)

Warum machen Leute sowas? //at 19:32 //by abe

Aus der Morons!-I'm-surrounded-by-Morons! Abteilung

Da bekomme ich doch von jemandem, der auch hier auf Planet Symlink schreibt, eine ICQ-Message mit dem Inhalt “ich werde alle chat netze bis auf skype deaktivieren und in zukunft nur noch via skype erreichbar sein.”.

Wieso machen Leute sowas? Ich mein’, kein ICQ mehr zu nutzen, das ist sicher ein Schritt in die richtige Richtung — den würde ich auch gerne mal machen, wenn nicht soviele gute alte Freunde ICQ als einziges IM-Protokoll verwenden würden. (Von AOL-, MSN- und Yahoo!-Messengern bin ich zum Glück verschont geblieben. :-)

Es stößt bei mir aber auf massives Unverständnis, sich stattdessen als einziges auf das proprietäre Chat-System einer unseriösen Firma zu verlassen, deren Vorgängerfirma bereits bekannt dafür ist, Spyware, Adware und andere Malware mit ihren Produkten zu vertreiben, deren Code und Protokolle durchtränkt sind von Verschleierung und deren Lizenzbestimnmungen der Firma mehr oder weniger erlauben mit den Rechnern der OpferKunden alles zu machen, wozu sie grade Lust haben, insbesondere zur Installation zusätzlicher, nicht für Skype notwendiger Software Dritter:

Sie erkennen an und stimmen zu, dass Skype-Software in andere Software und sonstige Technologie, die im Besitz und der Kontrolle von Drittparteien steht, integriert sein oder diese integrieren kann. Jegliche derartige Drittparteisoftware oder -technologie, die in die Skype-Software integriert ist, unterliegt dem Gültigkeitsbereich dieses Vertrags.

Wie war das nochmal mit Kazaa, was war bei Kazaa mit dabei? Was haben die Kazaa-Lite-Macher entfernt und deswegen Ärger bekommen?

Soviel zum Benutzerstandpunkt und dem gesunden Menschenverstand. Wenn man als Netzwerkadministrator mal eine sog. Skype-Supernode (vgl. Salman A. Baset, Henning Schulzrinne: An Analysis of the Skype Peer-to-Peer Internet Telephony Protocol) im Netz hatte, dann ist das Unverständnis für die Benutzung eines solchen Dienstes noch viel größer.

Für die Verwendung von ICQ habe ich doch noch deutlich mehr Verständnis, dort ist (oder war?) vorallem ein Bestandteil der Nutzungslizenz unschön: ICQ Inc. hat das Copyright an allem, was im ICQ-Chat übertragen wird, zumindest war das Ende 2005 Stand der Dinge. Die Lizenzbestimmungen von ICQ wurden allerdings zuletzt im April 2006 geändert und der von Netzpolitik.org zitierte Abschnitt ist in dieser oder ähnlicher Formulierung nicht mehr in den Lizenzbestimmungen zu finden. Was nicht heißen muß, daß dessen Bedeutung nicht nachwievor irgendwo in den Lizenzbestimmungen verklausuliert drinsteht. Dem sollte man sich einfach bewußt sein, wenn man ICQ nutzt. .oO( Hmmm, heißt das, daß ich für o.g. Zitat nun Lizenzgebühren an ICQ Inc. zahlen muß? )

Nichtsdestotrotz gibt es eine freie und verschlüsselbare Alternativen zu Skype und ICQ, bei denen man auch nicht auf die Software und den Goodwill (hmmm, das klingt fast schon zynisch an dieser Stelle ;-) einer einzelnen Firma angewiesen ist: Jabber (XMPP) und IP-Telefonie mit SIP. Von weniger auf 1:1-Kommunikation ausgelegten Chat-Systemen wie IRC, SILC oder PSYC mal ganz abgesehen.

Und wenn dann mal mein geliebtes IRC-to-IM-Gateway Bitlbee auch mal das verschlüsselte OTR Messaging unterstützt, dann juckt mich auch obiger Abschnitt aus den ICQ-Lizenzbestimmungen nicht mehr so sehr.

Hackergotchi of Axel Beckert

About...

This is the blog or weblog of Axel Stefan Beckert (aka abe or XTaran) who thought, he would never start blogging... (He also once thought, that there is no reason to switch to this new ugly Netscape thing because Mosaïc works fine. That was about 1996.) Well, times change...

He was born 1975 at Villingen-Schwenningen, made his Abitur at Schwäbisch Hall, studied Computer Science with minor Biology at University of Saarland at Saarbrücken (Germany) and now lives in Zürich (Switzerland), working at the IT Support Group (ISG) of the Departement of Physics at ETH Zurich.
