I just remembered something really cool that I had on my previous blog: a small box that shows information that “someone doesn’t want people to read”. It’s part of a brilliant campaign called “Irrepressible info” by Amnesty International. Many of you know that I’m very Amnesty-friendly (“supporter” might be too strong a word, since I’m not really doing much apart from being a member), and I think this campaign is just pure awesomeness.

The idea is very simple: you take texts that have been blocked in some country and allow people to show them in their own websites. It’s a simple but poweful way of showing your rejection for censorship and your support for freedom of expression. As for what you have to do to join the campaign, it couldn’t be simpler. You just have to copy some Javascript code from the instructions page and you’re set.

I have of course added the information box to the sidebar, under the “Irrepressible info” header.

Today I have had a gigantic e-mail spam attack. And by “gigantic” I mean something like one every couple of seconds. It seems to have stopped by now, though (maybe until tomorrow, sigh). However, there is some small tip that I used in the meantime, and I have found it helps me filtering spam so I thought I’d share with you. It’s very simple: ordering by subject instead of by date. Of course, you have to filter your view to only unread messages, but it works surprisingly well.

This is very easy to do in mutt, my mail reader of choice (for personal e-mail; I have found that, at least for work e-mail, Opera’s M2 works quite well too). You just have to limit to unread messages (pressing lowercase “L” and then using “~N” as filter), and then sort by subject (:set sort=subject). I have even created too “macros” in mutt to switch back and forth between “spam filtering mode” and “normal mode” :

 macro     index     \Cs     ":set sort=subject<return>l~N<return>"
 macro     index     \Cq     ":set sort=threads<return>lall<return>"

Let’s hope it doesn’t begin again tomorrow :-S

The last days I have noticed that most of the spam I receive has some made up news as subject. I imagine it is to make people click on the messages.

The point is that one of those messages was titled “Knol, the Wikipedia killer”, or something along those lines. I didn’t click on the message, and actually I just thought that “Knol” was a made up word… but then I thought “hm, maybe this exists after all”, so I went to the Wikipedia page… and there you go, I just found out about Knol and learned something about Music in Capoeira because of some spam message.

Informative spam. Go figure. Or maybe it means I should read more tech news?

In my recent trip to Copenhagen, I recorded a small video of the subway (it’s really cool, because it’s completely automatic, it doesn’t have drivers or anything). I wanted to edit the video to remove people that were reflected on the window, so I wondered if I could do that on Linux. I imagined it wouldn’t be trivial, but it was more frustrating than I thought. Maybe I’m too old for this.

The first thing I tried was looking in APT’s cache for “video editing”. The most promising was kino. I had tried that some time ago a couple of times, and I never made it to work, but I figured I would try again. Unfortunately, same result: I just can’t figure out how to import my videos. Maybe I’m just hitting the wrong button or whatever, but it’s really frustrating.

Second thing was having a look in the internet. I found the (dead and being rewritten?) Cinelerra, as always, and I didn’t feel like installing the old one from source, only to lose my time and not get it to work, so I just ignored it. Maybe they had it in debian-multimedia and wouldn’t have been a tough install after all. Anyway.

Next thing, I found some program called openmovieeditor. This one apparently worked, but I couldn’t figure out how to crop the image (or almost any other thing for that matter).

Next, some neat program written in Python, called pitivi. When I tried to run it though, it just said Error: Icon 'misc' not present in theme on the console and died. I later figured out that I had to install gnome-icon-theme for it to work (yeah, Debian maintainer’s fault). It’s funny, because on the webpage it says that it has some “advanced view” that you can access via the “View” menu… but I couldn’t find it. My menu only had one entry: “Fullscreen”. Great.

Oh, wait, there’s a gimp-gap. I could just import my animation in Gimp, crop the frames, and convert again to video. Easier said than done. I needed some programs that I didn’t have, and I wasn’t sure if they were so easy/quick/clean to install (sure, I could have exported to GIF animation and probably convert to video, I just didn’t want to lose so much color quality in the GIF step). Forget for now. At least I had the images, so if I could just turn them into a movie…

So, I started wondering if, given that I had decided to just crop, and especially now that I had a lot of images that were the frames, maybe I could just use some command line tool or something. So I found this tiny little program, images2mpg. Long story short, after installing some dependencies from source (that gave compilation errors, but luckily I could compile only the binaries I really needed) that program was completely retarded and didn’t even do what I wanted (it wanted at least one second between images, but I didn’t want a slideshow, just a normal movie from the frames). It looks some simple and it’s so buggy. Gah.

So I started wondering if I could just crop with mplayer... Hmmm… after a couple of problems (like documented switches that were not there and other crap), I ended up with this command line:

mencoder -vf crop=320:200:0:40 MVI_2160.AVI \
         -ovc lavc -nosound -o metro-crop.avi

That was reasonably quick and easy but it was so frustrating after all that lost time.

In any case, I ended up with the video I wanted, so I went to YouTube to upload it. When uploading, I realised that there was some option I had never seen: annotations.

YouTube annotations are really cool. They are like the notes on Flickr, but on a video :-D Actually I kind of wanted to make a note like that on this video, to show the automatic doors on the Metro station, so I was really happy to see that I could actually do it. And the interface is really easy to use and very clear. I really like it! You can see the result here:

EDIT: WTF? The annotations don’t appear on the embedded videos? You’ll have to go to the video page to see them, then…

Some time ago, Opera announced the Opera Web Standards Curriculum project. It’s a very interesting collection of articles that can be used as “curriculum” to learn about web development. It gets extra geeks points for using a Creative Commons license for the articles themselves. Even the W3C mentioned it :-) I just found some time to have a look at it, that’s why I’m posting now :-)

The other news is that finally the Opera QA blog is online, and has the first non-hello-world-article (written by yours truly), “Continuous Integration: Team Testing”. I’m very excited about this, because it’s the first time I’ll participate directly in a company blog, and because the IT world needs more (and better) QA, so hopefully we’ll be able to spread the word and make the world a better place :-D

21 May 2008. Dawn in Austria. A lot of policemen enter in 23 different premises with guns, battering down doors, harassing the people inside. They take 10 people under arrest. Dangerous terrorists? War criminals? Drug dealers?

Animal activists. There haven’t been any concrete charges yet, so they are basically prisoners of conscience. Some of them are in a hunger strike. It’s somewhat amazing that all that can happen in Austria in 2008.

Some more information:

• Petition to make them press charges or release them. Please sign it!
• Who’s being caged?, article in The Guardian
• Statement from Amnesty International in the Association against animal factories website.

Help stop this nonsense!

I read that Office 2007 won’t support ISO’s OOXML. There are two things I find funny in there:

1. After pushing for making OOXML a “standard format” (as in ISO), Microsoft is not implementing the standard spec after all (and won’t until some future version).
2. Microsoft is going to support ODF (competing, open format).

Of course, they want people to use a non-standard OOXML (the one currently in Office 2007 apparently), so they aren’t really in a hurry to support ISO’s OOXML, and their ODF support will probably not be perfect, so they’re just doing the usual stuff, trying to get people to use some format that they are in a better position to support. Oh well.

One week ago (but I just noticed), FFII published this press release about McCreevy trying to legalise Software Patents. I haven’t had time to read the whole thing, but this is just amazing. I mean, doesn’t Mr. McCreevy get fucking bored, if nothing else?

We don’t want your filthy software patents. We have said so many many times. Now go and [censored] yourself, find something useful to do for Europe.
