Talks continued

Later I attended the ALTQ talk by Adrian Penisoara. I persuaded Arjan van Leeuwen to install SubEthaEdit and it seems to work, although there are some limitations to a real revision control software.
Next talk was by dinoex about his work on a lightweighted package cluster and Yannick Cadin about DHCP (spent most of the time reading email so i didn't get much of the content). The last talk of the day was by Henning Brauer about bgpd. Interesting presentation but typical OpenBSD argumentation.
After that we left for the social event, an exhibition by Luigi Colani with a lot of airplanes and cars. Maybe I will upload some pictures later. Unfortunately the exhibition hall was cold and the band made a lot of Noise while trying to fight the enormous echoing.
We left early and drank a lot of beer at some pub mlaier recommended.
Today I am awake an hour too early because I forgot about Daylight saving time :-(
In 10 minutes rwatson starts the second day of talks.

Antti Kantee - "Using Application-Driven Checkpointing Logic for Hot Spare High Availability"

--> See conference proceedings.
- Good technical talk. interested attendantes.
- Outlines the possibilies, advantages and disadvantages of Userland Checkpointing.
- Good: Application knows about all the relevant data Bad: Every Application needs to adapted, Some parts like Network which are provied by the OS are difficult to access


agc & uwe@NetBSD.org: NetBSD on Handhelds
-- Nothing works out of the box, as usual with NetBSD :-). The Beamer doesn't recognize the screen resolution, slides are too large.
-- Nice Image of a portable Computer made out of a normal PC
-- showed a Journada with Windows CE.
-- lots of experimental stuff.
-- As usually agc's presentations are too long

keynote jkh

| | Comments (2)

Here are my short, badly formatted notes on jkh's keynote.

JKH
- showed a few stats, that BSD is the most common used UNIX (even more than Linux). 12.5 Million MacOS X users (Gartner Group?), 2.5 Million FreeBSD users (netcraft).
- introduced the BSD parts of MacOS X and IOKit.
-- Tiger will have UFS2 Userland based on FreeBSD 5.1
- outlined parts where Mac OS X is ahead of the BSDs, and where BSDs
needs work to stay state of the art
-- Authentification ACLs, nsswitch, OpenLDAP and Co.
-- Sound, FreeBSD users play mp3 and ...mp3
-- *BSDs don't support embedded machines without MMU (e.g no NetBSD on the IPOD)
-- Standards UNIX 03, Common Criteria etc.
-- Rendevouz

- Apple using OpenGL helps people avoiding DirectX
- promises that Apple will try to cooperate better with the OSS and more actively push back changes..
- He will continue to advocate UNIX and OSS inside of Apple. In the earliy 10.0 days he had to persuade people inside Apple needed to be persuaded to ship Terminal.app, today it is getting more popular.
--> promised to put slides later onto the Conference Webpage

BTW there are nearly more Macs than FreeBSD Laptops attending.
BTW2. If you are at the Conference and use a Mac, you can fix my notes using SubEthaEdit.

Countdown to EuroBSDCon

| | Comments (0) | TrackBacks (0)

Only two days left until EuroBSDCon starts. I still haven't organized a train ticket nor have i prepared my journey, because i am quite busy with university at the moment.
Unfortunately I can't attend the FreeBSD dev summit, because it start on Friday morning and I will arrive at Karlsruhe in the afternoon.

Via Hendrik:


I was tempted doing the quiz for a second time, trying to get the answers right for ".ogg". This Blog is not paris-hilton-video.blogspot.com and I am not wearing an ugly "pr0nstar" thirt!

Committed to FreeBSD

| | Comments (0) | TrackBacks (0)

Two years ago I became a FreeBSD committer.
According to Peter's CVS statistics since October 15 2002 I made 1664 commits to the ports repository (Currently rank 18), 29 commits to the doc+www repository, one src and one sys commit.
Because of the time consuming math courses this year, i failed to keep my rate of 1000 commits/year, but 663 is still nearly two commits/day. Additional I mentored two ports committers during their first steps as FreeBSD committers.
I have to thank Daniel and Jared who donated Hardware to support my work and of course the great FreeBSD community. I am looking forward to continue working on the FreeBSD world domination project with all of you.

Ill

As announced, today i joined the community of ill bloggers, again a sore throat.

After TELNET has been replaced by SSH in many cases and serious admins have started to replace FTP with SFTP/SCP the most common insecure protocols are IMAP and POP3.
Although most Emailprograms support a secure Emailprotocol the insecure variants are still much more common. I have installed the dovecot IMAP/POP3-server on my mailserver, but unfortunately at the moment it does not support SSL because the gnutls version in the FreeBSD ports collection is incompatible, so i read mail via SSH/mutt which is probably a lot faster than waiting until Mail.app has synced my 70MB mailbox over my ADSL line.
At university i always wonder that even computer science students don't think when they start their MUA while connected to the university WLAN.
And I wonder even more when I read their passwords, more than 15% of my small sample (a 45 minutes course) use their surname as password.

I am hosting my blog at home, and I know why. My second blog at twoday.tuwien.ac.at today gives an error 500. And i didn't made a backup ...

Murphy does not use KDE

| | Comments (0) | TrackBacks (0)

Everytime there is a FreeBSD release something in the KDE ports horrible breaks. This time:

  1. kdevelop didn't build on amd64, (okay this my fault, as i noticed this immediately after the 3.3.0 upgrade, but forgot to fix it).
  2. kdemultimedia failed to link after a last minute bsd.port.mk.patch. Big thanks for Andy Fawcett for tracking this down.
  3. kdm was broken in the 3.3.0 upgrade.
Can we now please finish the portsfreeze?

Buying CDs in Vienna

| | Comments (2)

Usually I am buying CDs at the Virgin Megastore, Mariahilfer Strasse. Unfortunately it is currently closed for refurbishment. Saturn doesn't really sell CDs I like, so where do people buy CDs in Vienna?
I don't know any other _large_ record store in Vienna :-(. Most people on IRC suggest Amazon, which is nice if you know what you want, but bad for searching around. At the Virgin you can listen to CDs for hours and there are always at least three CDs that I like.

Shut up and blog!

| | Comments (9) | TrackBacks (2)
Today I discovered keramida@'s blog and was quite surprised to find my own blog linked right next to mwlucas@ Big Scary Daemons.
Time to start a list of FreeBSD committers that write a blog, diaries, livejournals. (Although some take freefall's motd serious and prefer to code over writing blog entries) Disclaimer: This list is not complete, please add a comment if i forgot one. There is also the slight possibility that i added a wrong URL, especially as i neither speak Korean, Japanese or Chinese.

Update 2004-10-05: Added clsung, foxfair, grog, hosokawa, hrs, lth, mich, motoyuki, yoichi.

Update 2004-10-09: Added nyan, issei, nobutaka. Thanks to motoyuki who maintains a diarylist of the japanese BSD community

Update 2004-10-17: Added ijliao, remko

Update 2004-10-23: Added alex

When i wanted to buy my student ticket for public transport today, the clerk told me that i am too old. A few days ago I wrote about Fare dodging and now this is reality for me.
There are three possibilities to get to work: First I could use my knowledge about the ticket inspectors and become a professional fare dodger.
The second option is the bike, although my digicam does not support videos like Horst's and I need to sweat at least 30 minutes to get to university.
The third option is to use day tickets which are cheaper than the
The Annual ticket if i use the subway less than 270 days a year.
The third option is to add 60 EUR to my transport budget and buy the The Annual ticket
Hm.....

Uninitialized TCP timer

In May I wrote about an Accesspoint panic.
Today I got a similar panic with a different Software version. This time 12.2(15)XR2:

My WLAN

| | Comments (1) | TrackBacks (0)

I went Warwalking today and noticed that there are now 14 WLANs in my neighborhood, most of them secured by Mac-Address-filters or WEP.
Here is a map of my WLAN:
mywlan.png
With the second Accesspoint the whole garden is covered and unfortunately it is now visible from the Metropoldi.
The pink color shows the area where you should be able to connect to my WLAN, but I need to collect more data from the neighbor houses, especially the school (no 58-56) and the garage (Hernalser Hauptstr 57).

routed & RIP

| | Comments (0) | TrackBacks (0)

My home network gets more complicated with every device I add.
I made a new network diagram of my home network.
I am currently trying to use RIP via routed to announce the routes to the different networks (WLAN, FastEthernet, GigabitEthernet, FirewireEthernet and Internet). Unfortunately the documentation of routed on the internet is not very good. The Linux routed although based on the original BSD routed has diverged a lot from the current FreeBSD routed especially the syntax of the config file. Additional most people just start routed and it works, so there are very few /etc/gateways sample files on the net.
Currently announcing of the local networks works, but the default route isn't propageted the right way (always prefer the cable-networks over the wireless networks). Maybe one reason is, that my ADSL router doesn't announce the route to the Internet.

Feedbag Error

Today I reinstalled iChat, because I read, that iChat works with ICQ (well sort of) and because the MacOS Software Update program always suggest downloading the iChat security update. While trying to configure it, I got a strange bug:

Very funny translation error *lol*

Fare dodging in Vienna

| | Comments (3)

Vienna has an excellent public transport system and tickets are reasonable cheap, so many people living in Vienna have an annual ticket and there are very few ticket inspectors called "Schwarzkappler".
Some people even considered starting an insurance that pays the extra fees if you get caught.
Although I use the subway nearly daily it happens sometimes that i don't meet a ticket inspector for months. But sometimes you meet them everytime you enter the subway. There seems to be a rule of thumb that in the week before university starts or in the first week of the university holidays all employees of the Wiener Linien are trying to catch fare dodgers. (I wonder what they are doing the rest of the time).
From my experience the "safest" vehicle is the tram, especially in the Rush hour. Next is the S-Bahn in the City, as most of the �BB inspectors are starting to control tickets shortly before the S-Bahn leaves the City (Zone 100). Buses are only safe in the Rushhour, and most dangerous is the subway.
The most dangerous stations are Schottentor, Karlsplatz and L�ngenfeldgasse, because there are very few exits for a lot of people changing trains.
