Altered Carbon is a highly recommended SF-book.

Scientific development has always learnt a lot from SF. Maybe boody-sleeving will be next.

Average Salary of Lisp Jobs is greater than that of Java, C# or Ruby coders   28 Sep 06
[print link all ]
Interesting statistic. A Lisp coder earns on average $85k, while a Java-guy $76k. I wonder whether that statistic would change if one takes out the age-factor. :-)

Let’s admit it, Lisp coders are on average very smart, but so are the early ruby adapters .. and they get only on average $60k. Sniff ..

Update on Euruko06   27 Sep 06
[print link all ]

Short update, before the conference on Nov 4 and 5.

  • We are still evaluating whether we should get a bigger room. Sofar we have about 30 people that confirmed that they will show up. We have space for 50 people and might simple close the conference registration once we are fully booked and overbooked by 5% like these airline companies.
  • O’Reilly might give a free book to every speaker. Please add to the wiki what book you want. I will send off our wish list o O’Reilly around Oct 5.
  • Please put titles of your talks in the wiki, so that some structure will emerge. In the worst case we do a "planing-game" at the start of the conference and quickly produce the program as we did last year.
  • Get-Togethers will be announced in the wiki till Friday this week.

Looking forward to see you all again this year!

What is your favourite "programming musiuc" (non-technical question)   27 Sep 06
[print link all ]
I came across this insane Dilbert-like posting in the comp.lang.java.programmer group.

> Hi all,

 > When you are programming, what kind of music or which song you love to
 > hear? Is it classic music, piano, or pop music? Is it by male singer or
 > by female singer?

 I don't listen to music as such; I listen to an 8-second mp3-loop of my
 manager screeching, puce-faced, at the top voice, "WTF is taking you so
 long?!?! RELEASE THE CODE!!!! RELEASE THE CODE!!!! WTF AM I PAYING YOUR
 SALARY FOR?!?! RELEASE THE F%#KING CODE, YOUR WORTHLESS, DISGUSTING,
 INTOLERABLE PIECE OF S@&T!!!"

 > I think sometime hearing music would be helpful in
 > our productivity, right?

 I find that this mp3-loop truly helps <TWITCH> my productivity. I love
 <TWITCH> my manager, and dream of him <TWITCH><TWITCH><releases safety>
 often ...

I saw that a small team of good people seemed to outperform the most disciplined process, toolset, or philosophy. A bad team usually failed to produce a good result, regardless of what magic process was applied. Article

Ruby Hacking Guide   15 Jul 06
[print link all ]
This is the home page of the project to translate into English the Ruby Hacking Guide. The RHG is a book that explains how the ruby interpreter (the official C implementation of the Ruby language) works internally.

To fully understand it, you need a good knowledge of C and Ruby. The original book includes a Ruby tutorial (chapter 1), but it has not been translated yet, and we think there are more important chapters to translate first. So if you have not done it yet, you should read a book like the Pickaxe first.

Please note that this book was based on the source code of ruby 1.7.3 so there are a few small differences to the current version of ruby. However, these differences may make the source code simpler to understand and the Ruby Hacking Guide is a good starting point before looking into the ruby source code. The version of the source code used can be downloaded here: i.loveruby.net/ja/rhg/ar/ruby-rhg.tar.gz.

Many thanks to RubyForge for hosting us and to Minero AOKI for letting us translate his work.

I came across this useful posting by Gregor Gorjanc in the r-help ML.

  • R graphical manuals (this is awesome page as there are all help pages of all packages on CRAN and probably even more and all graphics examples are displayed! - more than 8000 images!)

This is a very nice addition to already existing R graph and movies galleries
