Ruby on Rails

There is a lot of inertia around Ruby on Rails lately. Boy those guys are good, look at this new video!

Nothing Remarkable

Nothing worth blogging lately, working, teaching, hanging around freenode#perl at night, and reading. My code editor has been mostly quiet at home.

Destiny's Child in Concert

I went yesterday night to see Destiny's Child in concert. I had a great time, the performance was somewhat commercial, somewhat sexual, and the sound not too good, but they transmitted that force so characteristic in their music. And, hey, Beyoncé is spectacular on the stage.

Unfortunately black musicians rarely visit Barcelona. I wish someday I see my favourites Erykah Badu, or D'Angelo.

Fake Certifications

Suddenly my cert counters in MyAdvogato report 5 new suspicious Masters. The corresponding accounts are clearly artificial, for instance this one. I don't see a pattern in the way the certs are assigned though. Is this some kind of attack to the trust metric? Just a way to trick Google? raph, any way to moderate this stuff?

Mac OS X 10.4, first hours

I couldn't install Tiger out of the box due to a problem in the disk, fsck reported more than 50 Overlapped extent allocation (file \d+). Lucky me, some guy documented what that means and how to fix it in single user mode. After that the installation was smooth.

There are infinite changes in Tiger, for infinite greater than 200. Some changes are cosmetic (as the merge of title and toolbars in some applications), some are major upgrades (as Xcode 2, or QuickTime 7, or Preview 3), some are important new additions (as Spotlight, or Dashboard, or Automator), and some are removals (as Stuffit). Tiger is the first Mac OS X where Java 1.5 runs, you can get it separately and it does not interfere with the installed 1.4.2.

I have to explore almost everything yet, for instance I have not touched Automator at all yet (I am very curious though about how they did approach the design of such a tool), but playing around with this new toy I noticed Safari RSS is fast, damn fast, in addition to have a cool interface to RSS feeds. The integration of Spotlight in the system is such a powerful feature that I am sure I can't foresee its secondary effects yet. One of the clear applications are smart folders (which are virtual, live folders defined by a query) in the Finder and in Mail.app, also upgraded. Mail.app by the way has been refined but has a new toolbar nobody seems to like.

I expected the result set in Spotlight searches to be more immediate than it is. Sure, they come up very quickly, but not immediately as I'd expect from an index and the demos in Apple conferences. I wondered for instance whether I could launch applications with Spotlight instead of with Quicksilver, but at least in this G4 that's not practical. Maybe that's dramatically improved in G5s.

Dashboard is an interesting addition. As people develop widgets that are helpful for me to have there, I'll see whether I integrate Dashboard in my desktop usage. I don't monitor flights so often :-), but the dictionary and the calendar are already useful for instance.

As usual John Siracusa has written a detailed review in Ars Technica.

Barcelona.pm Monthly Meeting

Barcelona.pm had its monthly meeting tonight. We were nine people today, and had a great time. This month I was the one to give the talk, which was a summary of the main changes since Perl 5.8.0. The presentation is in Catalan, I uploaded it in PDF format, and as an interactive QuickTime movie (1.9MB), where a few beautiful Keynote 2 transitions and animations can be seen.

Tiger Arrived Today

I have a nicely packaged black box in front of me, if everything goes fine my next entry will be written with Safari RSS :-).

Steve Ballmer Talk

I attended today the talk Steve Ballmer has given in Barcelona, in the Liceu. The public was heterogeneous, and perhaps because of that the content was, uhm, plain. Innovation is central to strategy, you must listen to your costumers, ..., that level. I didn't expect much from the talk itself, but I was curious about him and could see and hear him in live.

What's new since Perl 5.8.0

I have been working today in the presentation I'll give this week at the next Barcelona.pm meeting. The talk summarises the changes introduced since Perl 5.8.0, released back in July 2002. That comprises seven stable releases and a lot of stuff. I'll work on it until Thursday.


Last news about Perl, comments about Perl programming, reviews, and more, as weekly podcasts.

This week I have had the pleasure to meet Jan Wielemaker, the author of SWI-Prolog. I've been in Madrid in a meeting of an European Project I have recently joined in which Jan has worked.

Unfortunately he has done his part already and will be no longer involved in the project :-(.

That's a nice coincidence, back in 1998 I needed to do an immersion in Prolog. I used SWI-Prolog for that and since I was working as a proof-reader by then I did a careful revision of a couple of chapters of the user manual and sent it to him. He was very grateful and the corrections were merged.

Those days I followed The Art Of Prolog (1st Edition) and Prolog Programming in Depth. In case I play with Prolog again Jan recommended to study The Craft Of Prolog.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
