EURUKO 2008 Day 2
by Frank Spychalski filed under EURUKO, Ruby

Second day has started. Today it starts with a few talks on testing…

George Malamidis — „Synthesized Testing“

Already 15min behind schedule, but so far interesting.

This has 4 lines of code. It is already a big ruby function.

Vassilis Rizopoulos — „rutema: One test tool to rule them all“

I’m thinking on how to write in a polite way “This talk was boring”. It was. And the tool uses XML :-( Hey, this is a Ruby conference- you should use YAML or even better a cool Ruby DSL.

Tomasz Stachewicz — „Sharing the load“

Sounded interesting but there was a question after the talk which suggested that the guys reinvented the wheel and that BackgroundDrb is a better solution for what he has done.

Petr Krontorád — „Building Rails Playground - using Ruby’s dynamic nature“

Mumble, mumble, small text, cannot read the slides, mumble… Sorry I don’t have a clue what this talk is about.

Tim Becker — „Lessons Learned Writing Native Extensions“

Type-along tutorial on how to write C extension for Ruby. Very interesting, this could actually make me write C code again… He has started talking on cats and tigers and it seems like he wants to teach us how arrays work in C. Booooooooring. Finally he is done with this and is back on the interesting topics like conversion of data types. Overall a really interesting talk. By far the best one today so far. Tim’s post with code samples and links.

Matt Ford — „Aspect Oriented Programming in Ruby“

It’s his birthday. Happy birthday Matt! He talks about Aquarium a neat aspect oriented programming solution for Ruby. Very nice. I have to play around with this when I’m back home.

Dushan Wegner — „Philosophy & Programming“

This first lightning talk. “Imagine I’m holding a beer and put out this ideas”. “Programmers are better philosophers”. A very cool talk about the similarities of programming and practicing philosophy.

Marcin Raczkowski — „Distributed programming with ruby“

Hard to understand but interesting. Sadly it is impossible to read his code when he is showing examples in the editor.

sorry missed name and title Akira Tanaka - „IO.copy_stream“

Interesting talk about IO in Ruby. Great final “status” slide:

Accepted by Matz yesterday @La fabrica
Submitted today to Ruby 1.9


Gregor … — „Context-oriented programming for Ruby“

Took a long time to get to the point. Which part of lightning talk did you not understand.

Florian Gilcher — „Patterns (yet another) pattern matching library“

Interesting talk. Can be found at

Raimonds Simanovskis — „Using Ruby with Oracle“

Good quick talk. I never had to work with Oracle so I never had the problems he was talking about.

Daniel Liszka — „One RubyStack to Rule them All“

Strong accent, to much text on the slides. But sounds like a neat idea…

Ry Dahl — „Ebb Web Server“

Yet another Ruby web server, obviously it’s faster than all the others because what would be the point otherwise.

Wouter de Bie — „Capistrano, Webistrano“

The final lightning talk. I’m hungry :-) off to find some food…

Dr Nic — Demo

So it wasn’t the last talk. They squeezed in a short demo on how to use his gem generator. Very cool! I have to use this to play around with native C extensions.

Final announcement

It seems like next year’s EURUKO will be in Madrid. Great! Never been there. See you next year! It’s not decided yet. Krakow and Warsaw are possible sites, too. Hm, I’m still for Madrid :-)


I think I should have slept in today like Todd and would not have missed a bit. Here are some pictures from EURUKO 2008 on Flickr and even one with me. EURUKO was great. A big “thank you!” to all the people who have organized it. I’m sure I will be back next year, no matter where.

EURUKO 2008 Day 1
by Frank Spychalski filed under EURUKO, Ruby

The first day of EURUKO 2008 is over.

Yukihiro „Matz“ Matsumoto — „Keynote“

Matz talked about the future of Ruby. It was very interesting. He talked a little bit about the upcoming features (I will link to the slides when they become available) and about the design decisions behind Ruby. For me the most important quote was:

I designed Ruby not to work best but so that people can perform best

Koichi Sasada — „Ruby meets VM“

Koichi explained some details of YARV but some points were lost because a few of his slides were in Japanese.

Favorite quote:

(on his “No Ruby/No Life shirt”) for me it’s No Ruby / No Job

Charles Nutter and Thomas Enebo — „JRuby: Ready For Action!“

Made me download JRuby during the talk :-)

David A. Black — „Per-Object Behavior in Ruby“

I have to reread the slides, because I fell asleep (not due to the talk but to the fact that we are in Prague and had a few beer yesterday)

Nic Williams — „Meta-Meta-Programming with Ruby“

Memorable talk, very funny, great final slide (see @16:35)

Lightning talks session

Two talks on an agile white board and on a Ruby to PHP compiler.

VC with DHH

a little boring, bad sound quality and even worse video

One Laptop Per Child Germany
by Frank Spychalski filed under Computer

I just stumbled over an announcement about OLPC Germany. Last Tuesday was my first chance to play with an OLPC laptop. Everything but the keyboard feels incredibly solid and well made. The only thing I didn’t like was the user interface. I found it quite non-intuitive but perhaps this gets better if I spend a little more time with it. And if not: I can always put Ubuntu on it.

One thing is for sure: as soon as these laptops become available in Germany, I will buy one.

EURUKO 2008 — European Ruby Conference
by Frank Spychalski filed under EURUKO, Ruby

I just found out about EURUKO 2008. It will take plaze in Prague, Czech Republic, on March 29th to 30th. From what I’ve heard are EURUKOs fun events and I would like to go this year if I can find the time especially because of this announcement:

19. 02. 2008 · Matz is coming to EURUKO!
We are very happy to announce that Matz (most probably accompanied by Koichi) is coming to EURUKO! There are currently more than 100 people registered to attend, so thank you all! We will update the website in next couple of days with more details on program, information about sponsors and other stuff.

It has been some time since I used Ruby but it is still my favorite language by far.


I just registered for EURUKO :-) I will probably go by car so if someone from the Munich area needs a ride, just leave a comment… And a bonus feature: I found this Tech Talk of Matz talking about Ruby 1.9 today…

Dear developers…
by Frank Spychalski filed under Fun

…please learn about well formed URLs. And if it’s really too hard for you to figure out, I would be happy to come over and help for a Finals ticket or two :-)

What’s the problem?

I’m a nba fan and I subscribe to the RSS feed ( which works fine most of the time but sometimes I get an empty page. Why? Because some lazy developer thought it might be a good idea to add ?rss=true to every link.

If you look at todays feed you can find this item:

<title><![CDATA[Cavs' Gibson Expected to Miss Four to Six Weeks]]></title>

If I follow the link ESPN returns:

<!-- obj null -->

The suffix ?rss=true appears after every link in the feed so I’m pretty certain it’s not ESPN’s fault…


It’s even better. Not only do they destroy external links by appending ?rss=true, they kill their own links, too:

Should I buy a TS-409 Pro Turbo NAS?
by Frank Spychalski filed under Computer

I was thinking about buying a NAS (network attached storage) server for some time and looked at different products. My requirements are low power consuption, RAID support, and disk encryption.

My current favorite is the TS-409 Pro Turbo NAS. It has:

  • low power consuption (ok, sleep mode: 18.8W; in operation: 44.6W)
  • RAID support (way more features than I would ever need: Single disk, RAID 0 (Disk Stripping), RAID 1 (Disk Mirroring), RAID 5, RAID 5+ Hot spare, RAID 6, and JBOD (Linear Disk Volume))
  • no encryption

But I couldn’t find any other NAS server with a good price (less than 500€) and this combination of features so I guess I have to live without encrypted disks. If you have any experience with this box or know about another box which has all these features, please leave a comment.

I love starbucks
by Frank Spychalski filed under Rants, all

I moved to Munich a few month ago - well actually I move to Munich only a few days ago but my stuff is here for a few months already. But anyway, I don’t have DSL yet. There are 6 or 7 WLANs in my building but these damn neighbors know how to set a password. This means I feel like living on a remote island far away from civilization when I’m at home. About an hour ago I brought my GF to the train station and luckily there is a Starbucks with a hotspot. With my iPass account I can access it without paying to 8EUR/h and get my fix of internet today ;-)

Geeky christmas present
by Frank Spychalski filed under Fun

I got a nice Lego mindstorm box for Christmas. It’s extremely cool. The graphical programming interface is a little bit childish but good enough to build the first few robots. Funny that nowadays building the robot is the most difficult part for such a project :-)

Things to do:

  • Watch and try everything from NXT Tutorial.
  • Try Ruby-nxt. The project seems stale because status is still alpha and last update in November 2006. I would love to use my favorite language to control the robots I’m going to build. :-)
  • Have a look at the NXT firmware.
  • Look at all the other ways to program the NXT.
