Carlin will be six tomorrow. Six weeks, that is.

First time I've read recentlog from beginning to end in, well it would be since about six weeks ago...

ncm: Thanks three times for your congratulations messages, and it is excellent to see such finely calculated mischief as the "I Hate Java" community at Orkut. I almost wish I was a Java hater myself...

And re monotone: indeed, and not only is it well coded, the design is deeply revolutionary. Hackers of the world unite, you have nothing to lose but your beauty sleep! Join the revolution now, while you can be one of its heroes...

fxn: Thanks and congratulations yourself. BETA around 120 days? That should be in an easy patch IIRC :>

badvogato: Quite so, but I posted on the 25th and was wishing my readers a happy new chinese year. Carlin indeed falls under the sign of black sheep/goat, and since she is also a Capricorn, astrologers might get a bit excited about her goaty spiritual influences.

Carlin Stewart-Wiese
Our baby daughter was born late on Tuesday night (20th January), at 10:55 pm (Berlin time), weighing 3.38kg (7lbs 7oz), and 51 cm long. You can see a photo of her.

The birth was very tough on my wife, but she's recovering well, and Carlin is healthy, happy and hungry.

And happy year of the monkey, everyone...

Tutorial on Graph Transformation
Since using graph based representations for all kinds of data is becoming more and more popular, I think it is a good time to remind the wider world that sleepy academia has come up with some nice machinery for performing transformations on graphs, especially the so-called single- and double- pushout approaches. There's a bit of category theory needed to understand what is going on, but only a little bit; much, much less than is needed to understand what is going on with monads in functional programming, for instance.

The best introduction I know is Tutorial introduction to the algebraic approach of graph grammars based on double and single pushouts by Hartmut Ehrig (a former employer of mine), and two coauthors.

Unfortunately it is not online; in its place I can suggest Practical Use of Graph Rewriting. I'd be delighted to know of any other recommendations.

BETA=15 days.

What's Wrong with Romanticism?
Gian-Carlo Rota wrote:
The idea of genius, elaborated by German romantics, is destructive; it is a night into fantasy. There is reason to believe we've killed classical music because of that idea. People think that they will be either geniuses like Beethoven or nothing. But look at the Baroque Age--there were hundreds of little Italians who wrote good music and didn't give a hoot about being creative.

Random Remarks
tk and mslicker are behaving like idiots in lkcl's very timely and constructive article's comment thread...

I see that Paul Graham has a book coming in May.

dyork: Don't leave us, please! Belonging to the free software community is a vocational sort of thing, not associated with this or that project. Your diary entries enrich advogato even when they are not filled with LPI, DocBook, etc.

Happy New Year, advogato!
I had a wonderful New Year celebration with my wife, in the mists of the gunpowdery fog that is Kreuzberg, Berlin at this time of year, at our favourite pub, Max und Moritz. Now just 3 weeks to go before our daughter is born.

Computer science weblogs
Probably the academic discipline that gets best value out of the weblog phenomenon is law, with a good number of excellent weblogs devoted to both general and specialist subjects. Computer science is pretty disappointing by comparison, but here's a selection of some weblogs that are battling the odds. (There are also some weblogs here by non-computer scientists, which I tend to count as one of us if there is a heavy language design focus).

Lambda the Ultimate This is just clearly the best computer science weblog out there; it has no close competitors. Here's a selection of excellent posts, taken almost at random:

Pinku Surana's Green Hat Journal: probably my favourite individual blog by a computer scientist. Some of his best past posts:

Matt Jadud's weblog How do you compile?, who also runs the Cool Stuff in Computer Science weblog. Focus on didactics of computer science; some sample posts:

Bill Clementson's Blog, a Common LISPer. Some samples:

  1. Continuation-based web frameworks
  2. Kenny Tilton's Cells
  3. A CLer learns scheme

Ian Wehermann's the maine paige. Sample posts:

  1. Generalized logic and proof
  2. on the web's first semantic application

John D. Mitchell's blog (he also keeps an artima.com blog. Java programmer. Samples:

Bjorn Borud's Random Scribblings; samples:

Gordon Weakliem's 80/20; samples:

Will Benton's Free Variable. Sample post: Thinking like a computer scientist

Cay Horstmann's rather sparse artima.com blog; sample post: Some objects are more equal than others

Jim Coplien's Artima.com artima.com blog has just this single entry, which makes it more an essay than a weblog: Teaching OO: Putting the Object back into OOD.

Katz's Web; sample on Inference Web: Explanations on the Semantic Web

More to follow: I'll keep this post updated. Recommendations sought; you can email me at cas@janeway.inf.tu-dresden.de.

RPG Interview
I didn't see this at the time, so other's may have missed it: there's an interview with Richard Gabriel at developers.sun.com, on poetry, the skill of programming and his Feyerabend Project. Via John D. Mitchell.
Update: RPG's excellent book, Patterns of Software [PDF] is available online.

ncm: Of course Iain makes political mileage of this, and I'm not so much in favour of where he goes with it, but he did have the most interesting content at the time. Is the motive of the Danish Ministry of Science political? Of course, and Lomborg was appointed director of the Danish Environmental Assessment Institute. Having said that, firstly the information available make clear that the DCSD's decision was bad: cf. an english summary of the published decision. How can you call "the DCSD has not substantiated it's case" a minor procedural irregularity? Second, though Iain made no particular point with "statist", the adjective does identify a fault-line in Green politics, which my own contact with the Green party here in Germany seconds.

badvogato: Sorry, Authorisation Central informs me that admission to Building #1 has been denied.

redi: What makes you so sure that Islamism is not a word of British English? You can't tell these things by looking up the dictionary: language change moves at a fair pace, and dictionaries are always just trying to catch up. Are neologisms wrong until they make it into the OED?

yeupou: I disagree a little: I'd define Islamism as Islamic anti-secularism. This need not be extremist, though: the ruling Turkish Justice and Development Party is widely considered to be both Islamist and moderate.

zhaoway: I said mysterious, because you keep on dropping this intriguing hints about software development you are doing, and then won't say anymore.

Danish ministry of science quashes DCSD ruling against Bjorn Lomborg
For those who followed the controversy over Bjorn Lomborg's book The Skeptical Environmentalist, there is interesting news: the Danish Committee on Scientific Dishonesty, which judged Lomborg guilty of scientific dishonesty in early 2002, has now had its ruling quashed by the Danish Ministry of Science. There is some informative commentary by Iain Murray.

As an aside, I find it interesting that Murray, a conservative, calls Lomborg an inconvenience for statist environmentalists; there's a presumed contrast with non-statist environmentalists. It reminds me, for the second time time today of the small Green Libertarian movement, that began, I believe in the early 1990s.

pfh: I am strangely fascinated by your electronic singing tortoise. But I will resist the urge to download its song!

huge: It looks like Meerkat has become more sophisticated recently. Still, you might be interested in Pears. The mysterious (ie. I can't figure our h(is|er) name) developer is rather responsive.
