BarCamp Zurich — Resumé //at 02:02 //by abe

The BarCamp Zurich 2006 is over. On the way there I thought about what I would do during time slots with no interesting talks. But when I tried to make up my personal schedule, I noticed that I rather would have the opposite problem: Too many interesting talks at the same time… Well, to many interesting talks at all, although I only went to tech talks and left out the biz talks.

I first went to the Podcasting & Co. talk by Timo Hetzel, since I never heard or made a podcast, but was curious about podcasts in general. Besides statistics and rankings he spoke about where people listen to podcast (most listeners seem to do that during commuting), what people like in podcasts, why companies podcast, etc. And that a very big share of all podcast listeners use iTunes as podcast client and except juice (never heard of it before) all other podcast clients seem to be irrelevant.

My conclusion: I haven’t missed anything not having listened to or made podcasts neither do I need to listen or make podcasts in the future. They’re irrelevant. To me. :-)

Then I had to choose between the talks AJAX@localhost (PDF) by Harry Fuecks and Realtime Collaborative Text Editing and SubEthaEdit by the Coding Monkeys. I heard about realtime collaborative editing once know that it’s a challenging task for the developer. I also know what AJAX is (and that I would only use or recommend it for bells and whistles, but not for content in general), but “AJAX@localhost” sounded like writing normal applications using AJAX. It sounded interesting and evil at the same time. I had to go there! ;-) Others had similar expectations after reading the talk’s title, so I was quite surprised that it was about something completely different, namely about debugging AJAX on the localhost but under conditions usually only appearing if you’re running AJAX application not from localhost but from somewhere on the net: You may have different lags with every request, so some requests may reach the server before others, which may screw up the whole AJAX application, if the developers didn’t think about it and only tested it on localhost. (Hence the talk’s title…)

My conlusion: I will use and recommend AJAX even more seldom, since there seem to be even more design misconceptions than I thought before. But I’ll once have a look at the Webtuesday meeting, he mentioned.

For the third time-slot, I didn’t need long to decide where to go: I already knew a little bit about Microformats and I wanted to know more. Tag Trade also sounded interesting, but the second part of the talk’s title, Paid Learning sounded like business and so I had no scruples to cold-shoulder that talk. I probably didn’t learn anything really new in the microformats talk, but my knowledge about microformats is now more concrete, and after talking with Cédric Hüsler later during a break, I would even trust myself to start and define a new microformat.

Then I went to the HG Caféteria together with Gürkan and two German guys. While waiting in the queue, we were talking about our jobs and our favourite Linux distributions. I got some rhubarb pie and a rum truffles, assuming that the Caféteria uses no alcohol in their products like all other SV restaurant I know. But this one seemed to have quite a lot of alcohol, since it felt like my breath was burning… Well, this resulted in my second SV feedback form submission…

Next I went to Alex Schröder’s talk about multilingual websites, Oddmuse and the Emacs Wiki, although also the talk A-Life about simulating evolution sounded promising. Alex asked the listeners about their experiences with multilingual websites and showed what Oddmuse offers as partial solution to the general multilingualism problems. But regarding the comments from the auditorium, there probably won’t be a perfect solution until computers can translate perfectly…

The next talk I visited was Gabor’s talk about his master thesis Organizing E-Mail which resulted in a soon to be released Mozilla Thunderbird extension called BuzzTrack. From the other concepts he showed, I found Microsoft’s SNARF (Social Network and Relationship Finder) and IBM’s Thread Arcs most interesting as well as the fact that there is no e-mail client seems to have a majority at all.

Directly after Gabor I had my own talk about Understanding Shell Quoting, so I also couldn’t go to Adrian Heydecker’s talk about Learning with Hypertext and Search Engines. I had only about three and a half listeners of whom several to my surprise where here because they didn’t know what “shell quoting” is.

I really didn’t expect that.

But that seems to be one of the differences between a BarCamp and a Linux Conferences: People come here to see something new, something they haven’t heard about before. On Linux events most people come, because they already heard about some special topic and want to know more or learn something about it. On Linux event my shell talks usually were attracting many visitors while at a BarCamp, talks presenting an idea, a concept or a tool seem to much more interesting for the attendees. So for the next BarCamp I perhaps exhume my Website Meta Language talk which never seemed to hit the nerve of Linux event attendees, since it tried to “sell” a different concept of generating website than most were used to.

At least one listener excepted the talk to be named “shell escaping”, but IMHO escaping is only one quoting technic and it’s not only used for quoting. But perhaps I should take the word “escaping” in the title though for the next time.

Happily most of the listeners seem to have learned something new from the talk and Silvan Gebhardt was really happy about his new knowledge about ssh ~ escapes, although I mainly talked about how to quote them than how to use them. :-)

During the last slot I visited the session about the upcoming BarCamp Alsace 2 and the yet to be planned BarCamp Rhine, a BarCamp to be held on a ship traveling from Basel in Switzerland down the Rhine, stopping in Strasbourg, Karlsruhe, Rhein-Main-Area and perhaps even Cologne and Amsterdam.

Contrary to my initial thoughts, the day was over very fast and I had no single boring minute during the BarCamp. Wow!

After we’ve been kicked out of the building by ETH janitors, we joined again at the Bar N-68. On the way there I met Urban Müller who attended BarCamp Zurich, too. We talked quite a lot and it was very interesting to see behind the scenes of e.g. map.search.ch. Later I joined the French speaking table, talking with Gregoire Japiot from WineCamp France and Alex Schröder.

Around 9pm I left the N-68 as one of the last BarCampers, tired but with new knowledge, new ideas, new acquaintances and a new hobby: BarCamping. What a luck that BarCamps aren’t that often, otherwise I couldn’t afford this new hobby. ;-)

As a relaxing end I met with Alex Schröder and Christophe Ducamp on Sunday morning for brunch in the restaurant Gloria in the Industriequartier. When we were leaving the Gloria I noticed their book board with a lots of BookCrossing books and I took “The Da Vinci Code” with me, since I saw the movie and people were telling me that the book is much better. I’ll see…

Next Shell Quoting Talks //at 12:33 //by abe

There are a several events coming up where I plan to hold my Shell Quoting Talk: First, there will be the BarCamp Zurich on October, the 28th at ETH Zürich HG and then there will be the 8th Linuxday.at on November, the 18th at the HTL at Dornbirn (Vorarlberg, Austria) organised by the LUG Vorarlberg. It’s also possible that, in addition to the Shell Quoting talk, I’ll also give a talk for beginners about Commandline Helpers. (Probably all the talks will be held in German.)

I’m quite curious on both events, for very different reasons. On the one hand, a BarCamp is something completely new for me and it sounds like a very interesting mixture of a real life Wikipedia meeting and a flash mob to me.

On the other hand, this year’s Linuxday.at will have several new facettes for me: First there were several changes in the organising team, so I wonder if and in that case how much this will change the face of the event. Then it’s the first Linxuday.at since I live in Zurich, which means it’s the first Linuxday without 1000km travelling during that weekend, so I also have some time to meet friends in the area in advance to or after the event. Yeah!

Nice Shell Bloomer //at 16:39 //by abe

While looking for users which still have “.” in their path, I found the following nice bloomer:

PATH=``$PATH:.:$HOME/bin''

It’s obvious what the user tried to do. But why the fuck does this (more or less man or info page alike) quoting syntax work?

It took me a moment to realise that this kind of “quoting” works in nearly all Unix shells: The two backquotes as well as the two single quotes become an empty string and are therefor completely useless in this case.

The user probably read some uglily localized man or info page (like the German ones in Debian Sarge) and did some copy and paste to his .bashrc. And since it “worked” he didn’t see any reason to change it again.

Back from Chemnitz //at 09:50 //by abe

I’m back from Chemnitzer Linux-Tage (CLT) which were really great. The CLT organizers really know how to make an event for the community without forgetting the business people.

So, although Murphy hunted me with forgotten laptop power supplies, forgotten laptop power supply power cords (Thanks for the spare, Venty!), missed trains, late trains, unfitting train schedules, defective mobile phones (Hi Sven! :-), heavy snowing, addictive Play Station Portables and no time for attending a single talk except mine (I’m sorry, blindcoder), I held all three talks as planned — maybe except the duration — and had a lot of fun as expected.

The slides for my commandline beginner’s talk on Sunday were finished the same day at about 2am and are online since then. It was too long, but except the next presenter (Hi Werner!), nobody told me. I even thought that all those people entering the room were late listeners. I just didn’t notice at all that time was flying by so fast, since there was a lot of interesting discussion with and in the audience, something I didn’t expect from a beginners talk.

Thanks to all who already gave feedback to my talks. And thanks to Jens Kühnel and Henrik Heigl with whom I could drive back to Frankfurt.

LUGS-Vortrag für Einsteiger: Die Helfer der Kommandozeile //at 10:16 //by abe

Am nächsten LUGS-Treff (Donnerstag, 1. Juni 2006, 19:15 Uhr, ETH Zürich, HG, Raum E 21) werde ich einen etwa ¾-stündigen Vortrag für Kommandozeilen-Einsteiger halten. Der Vortrag soll einerseits ein wenig die Angst vor der Kommandozeile nehmen (“Kommandozeile ist ganz einfach.”) und andererseits die Gemeinsamkeiten vieler häufig genutzter Kommandozeilenprogramme aufzeigen: “Da ist (einigermaßen) System dahinter.”

Zielgruppe sind Linux-Benutzer, die bisher Linux nur auf der grafischen Oberfläche — sei es mit KDE, GNOME oder XFCE — kennengelernt haben oder sich noch nicht an die Kommandozeile heran getraut haben.

Dementsprechend würde ich mich auch freuen, wenn nicht nur die üblichen Verdächtigen -äh- Gurus selbst kommen würden – die werden an diesem Vortrag nix lernen – sondern diese auch all ihre Geschwister, Eltern, Großeltern, Kinder, Enkel, Freunde, etc. mitbringen würden, denen sie ein Linux oder ein BSD schon immer aufdrängen wollten, aber immer an so Fragen wie »Ich habe mich eingeloggt und sehe nur “linux FAQ) gescheitert sind.

Update 00:31 Uhr: Die vorläufigen Folien zum Vortrag sind online.

Slides for Berlin and Chemnitz online //at 01:47 //by abe

The slides for my next two shell efficiency talks are now online.

I’ll hold one 1.5h talk on Thursday, 2nd of March, 19:30h at the New Thinking Store in Berlin Mitte. Thanks to Sven Guckes for the idea and for bringing me in contact (again) with New Thinking.

The second will be a 3h workshop on Saturday, 4th of March at the Chemnitzer Linux-Tage.

I’ll also hold a short 30min talk for beginners about the “Command line helper” on Sunday, the 5th of March, 10:00h at the Chemnitzer Linux-Tage. The slides for this talk will follow during this week.

All talks will be held in German.

Update, 12:57h: I’ll travel from Berlin to Chemnitz with the famous LinuxBus and there are still some seats free. So if you plan to come from Berlin to Chemnitz and want us to join, please quickly contact Frank Hofmann <linuxbus@efho.de> for reservation.

Talk proposal for Chemnitzer Linux-Tage 2006 accepted //at 01:47 //by abe

My workshop proposal for the Chemnitzer Linux-Tage 2006 has been accepted last week. But in addition to it, they asked if I can also hold a talk for beginners about the basic command line utilities, since one presenter had to cancel his offer. But nevertheless they wanted such a talk in their schedule. So I’ll also give a short 30 minutes introduction to basic command line utilities as e.g. ls, rm, cp and mv.

Since I heard no contrary statement, I expect the talks to be held in German.
