Triple negations

Submitted by gwolf on Thu, 12/06/2007 - 15:18

I'm packaging Ruby's PDF::Writer module for Debian - It is a simple module and (almost) ready for upload. But anyway, it carries some issues I had to bring to debian-legal's attention, mainly, five files licensed under Creative Commons licenses (specially two of them, which are under its NonCommercial variant - clearly non-free), so I'm repackaging the .orig.tar.gz into a +dfsg version.

But I know I'm a lazy and sometimes stupid bum. Even more, the package will be group-maintained by the pkg-ruby-extras team, so we must be as careful as possible not to forget to remove the non-free material - To remove two scripts, and to replace three images with free equivalents I just made. But hey, tell me if this does not feel ugly to you. At least to the bits of you who learnt human grammar:

clean::
	# Make sure we strip out non-DFSG demo files from the orig.tar.gz
	[ ! -f demo/qr-library.rb -a ! -f demo/qr-language.rb ] || false 
	[ $$(md5sum images/bluesmoke.jpg | cut -f 1 -d ' ') == 0586eca5af7523ab871609eceb44724a ] || false
	[ $$(md5sum images/chunkybacon.jpg | cut -f 1 -d ' ') == a000b1917142ce332fd3474f0722cd6f ] || false
	[ $$(md5sum images/chunkybacon.png | cut -f 1 -d ' ') == 927feec1cbbf23c4d89a4a5ad88e6d0f ] || false

Triple negations. How nice.

Hot water and long pipes

Submitted by gwolf on Mon, 07/30/2007 - 18:07
Every now and then, I see somebody who -just as Russell did today- talks about the advantages of water heating systems not being tank-based, but tankless! Sounds kewl, hah? Shiny, new?
Well... I live at a house that is slowly but steadily started to show its age. Built in 1955 and owned for almost two decades by the very renowned phycisist (of course, my father's mentor and teacher) Marcos Moshinsky, my parents bought it in 1974, and it has been my home since 1976. And, at least since 1980 (I cannot be sure about earlier events for reasons that might be obvious to the casual reader), we have always had an Calentador Ascot de paso. Ascot (and further companies that have bought their name) have manufacutred this kind of water heaters for at least 60 years in Mexico. Yes, they are gas-based and not electricals like the ones Rusell links to, but that might just be because in Mexico gas has always been incredibly cheaper than electricity. And yes, the heater is godsent for ecolocigally conscious people - No more storing 20 to 40 lt (the sizes of the usual storage-based tanks around here) of hot water all day around just because you might want to take a shower, no more waiting for 20 minutes after you turn it on until you start having your morning shower (and more important, no more taking your morning shower ice-cold just because you overslept!)
Yes, it seems like life is perfect with our tankless (de paso) system... Almost.
As I said, our house was built over 50 years ago. It was built on what intended by then to be a middle-upper class suburb, on a very modern house with fancy stuff and all. And of course, the heater was not planned for the most visible or hearable areas of the house - specifically, nowhere close the living room - or the bedrooms. Silly details, the bathrooms are close to those areas. So, what's the answer? Want to take a shower? Ok, open the water...
And wait.
For around 3-5 minutes, until the hot water finishes the looong ride from the opposite corner of the house.
Of course, it takes a path that's not easy to intercept in order to move the heater to a saner place: The hot water pipe goes right under the middle of the living room, yay.
So we use our fancy de paso system whenever we are too lazy. Nadezhda and I prefer to fill one hot water bucket (~20lt) for each in the washing room, just by the kitchen (and the heater, of course!) and throw hot water over us to get a nice bath. Or, in case we are too lazy for that, collect as much as possible from the otherwise-wasted hot water in another bucket (we usually get ~10lt - but I fear another such amount just falls around it) and use it later for our various household duties.

Celebrated 10 years of the SC

Submitted by gwolf on Fri, 07/06/2007 - 06:08
Following Liw's initiative, yesterday night Nadezhda and me joined the distributed pancake party. With a nearby restaurant's hotcakes, anyway, not as fresh or as great as they could, but you can still smell the spirit:

(artwork by Nadezhda)
And... Well, it was not until this morning that I checked on the Wiki just to discover that Damog took part of the same distributed party, just ~15km away from us. Shame - I had just met Damog that very morning at the University :)

Top-down and bottom-up: Two approaches for... Hydrodynamics?

Submitted by gwolf on Thu, 05/24/2007 - 09:52
Yesterday we had one of our first full-evening rains of this Summer. It started raining around 15:00, and didn't really stop until past 22:00. Most of the time, it was a low intensity rain. Also yesterday, Sergio and I started with the Debian course I recently talked about - Fun!
Now... This course is scheduled at Instituto de Astronomía, which is halfway between my work and my home. 19:00 to 21:00.
I decided to leave early, so we could check some pending details - At 18:00. I biked to Astronomía, about 1.5km. When I arrived, I was as wet as you usually get at a regular rain: I still had some dry spots under my arms and legs. Nothing terrible, although a bit coldish - Anyway, that's a top-down approach for hydrodinamics, the approach most people are used to.
When we finished this session, I had to go out in a rush, as I had a meeting at 20:00 at Balderas (downtown Mexico City, ~25min away by metro). Of course, I was one hour late already, and adding the time it would take me to get home, leave the bike and run to the metro, I could not just sit and wait for the rain to get any easier on me. So I pedalled.
Contrary to what I originally expected, I didn't get soaked wet in the usual pattern. Stronger rain leads to more rain flowing down the road. Yes, almost immediately I felt a cold shudder on my legs and back: The water sprayed from below by my wheels. Of course, the front wheel was even more fun, as it sprayed my face from below - My helmet has a small protuberance at the front to make some shadow, and tilting a bit my head forward prevented the rain from hitting my eyes - but the dirty water, with small bits of wood and whatnot, from the ground found an easy way to my face. My only defense was to close the eyes as much as I could without losing visibility. A strange excercise to do :) Anyway, that's the bottom-up approach for hydrodinamics.
Anyway, by the time I got home, after an extra ~1.5km, my pants were basically a soup. My shirt was not exactly dry, but it still kept me a bit warm. I just ushered inside, grabbed a jacket, and went on for my second meeting.

On sending out the right image

Submitted by gwolf on Tue, 05/22/2007 - 22:29
At my Institute, we get the El Financiero newspaper - I like it quite a bit. It's very well balanced, with opinions from all of the political and economical points of view. Of course, it has huge business and market sections which I don't usually even care on looking at, as I won't understand much anyway. Those sections usually include advertisements for potential courses and businesses.
Today, Nadezhda showed me an ad that's just beautiful - It shows off the level of commitment and seriousness a company has. It is so beautiful that it deserves me copying it in Spanish and translating it for your further enjoyment. Of course, if somebody stumbles upon this advertisement at my personal blog - I don't know them, they might just be serious but clueless :)

Yes, several of the redaction mistakes are in the original text (and several more were introduced due to my English translation, of course).
Anyway... Would you believe in the seriousness of a professional-looking group of economists, paying around US$2000 for 1/4 page in one of the leading Mexican newspapers? By the way, their offices are located at one of Mexico City's most exclusive, expensive areas. But... For ${deity}'s sake... COME ON! Please tell juan_zzz to get a decent-looking mail and domain! Having their main contact addresses at two free mail providers, Starmedia and Yahoo, does no service at all to their professional image! How can people still not pay even a bit of attention to those basic details?

When bad system design leads to pain...

Submitted by gwolf on Thu, 05/17/2007 - 10:22
A long time ago, I wrote the system that still manages the Cuerpo Académico Historia del Presente group in the Universidad Pedagógica Nacional. Yes, I'm happy a good portion of my project, which took me over a year of work... But I must admit a nice deal of shame as well.
Of course, it comes from not properly understanding the domain data and information volume my system would be working with - and coming up with a stupid way to implement searches. I won't get too much in detail because, even if you had access to the full search facility in the system (no, it's not available for the general public), I would not like a swarm of curious people to make last week's events come back... Anyway, the group works by daily filling in tens or hundreds of articles in the system, and having some interesting search sessions every couple of months.
I knew the performance problem was caused by an inefficient searching mechanism (explicitly, category exclusion is the prime killer). I knew loadavg jumped through the roof, memory usage did so as well... But it was not until some weeks ago we installed the mighty Munin on the machines at UPN that we got this jewel - Thanks, Victor, for putting the graphics somewhere they can be shown! ;-)
So... How much does memory usage increase during searches?

Whoa. The system has 640MB real RAM. It has as well 1GB swap. Don't ask me how the hell it reports it was using ~2GB swap - but still... And how is our load average?

Have you ever seen a (single CPU, Pentium 4 1.7GHz) Linux system with a loadavg of 80?! For those who don't know, loadavg gives you the general status on how many jobs are pending scheduling by the CPU. 1 means that all of the CPU's time during a specified timeframe was used (and, on single-core systems, it's the optimal usage level). On this machine, things start getting uncomfortable at 6 or 7. I had never before seen values even half this large.
Sigh... Well, in my defense, I must say I've warned them about this problem for over two years. My contract with them has long passed - I've repeatedly recommended them to hire somebody to fix it. So far, they have not.

This looks like random blabbering, right? A very specific random blabbering that has somehow appeared in blogs of at least tens (if not hundreds, maybe even more) blogs of techies all over the place. What is it?
For the more tech-friendly readers, it has some resemlance to a number - a long number, a 32128 bit one. And for those of you who are not Computer Science minded, you might actually prefer to see it as a simple base-10 (that means, decimal system) number: 13'256,278'887,989'457,651'018,865'901,401'704,640. I don't know how to spell it in English, but I do in Spanish (why? Because we have this difference: In Spanish, a billion is a million millions, and a trillion is a million billions - unlike English, where a billion is a thousand millions and a trillion is a thousand billions). So, lets do the excercise in Spanish:
Trece sextillones, doscientos cinuenta y seis mil doscientos setenta y ocho quintillones, ochocientos ochenta y siete mil novecientos ochenta y nueve cuatrillones, cuatrocientos cincuenta y siete mil seiscientos cincuenta y un trillones, dieciochomil ochocientos sesenta y cinco billones, novecientos un mil cuatrocientos un millones, setecientos cuatromil seiscientos cuarenta
Hah! I guess my fifth-grade teacher would be quite proud of me!
Now, I hereby pronounce my transcription of this utterly long and basically random-generated number into the beautiful Spanish language copyrighted by me, and publicly available under the Creative Commons Attribution-ShareAlike 3.0 Unported License, as it is a very valuable and hard literary work.
But, really, what is it? Well, this mindboggingly long number is the key with which most HD-DVD movies processed so far is encrypted with. Of course, the Motion Picture Ass. of America (MPAA) does not want this (again, randomly generated) number to be out there in the wild, so they say the number is copyrighted by them - This does not hold up, as it has been widely shown before (i.e. Intel dropped its 286/386/486 numbering scheme because a number is not copyrightable or trademarkable - and AMD was perfectly able to legally sell 386/486 chips). So, I have put more work into this number than what they have. I deserve the credit - the transcription is mine. Use it freely.
Oh, and of course, some more examples:[update]: Yes, sorry, I was counting with half of my brain shut down and the other half brain trying to fetch some coffeine, or something like that. It's a 128 bit number, not 32!

Dude, where's my country? Seems like Google doesn't know

Submitted by gwolf on Wed, 04/25/2007 - 23:35
I was trying to make a credit-card purchase on the web. The site I was trying to give money to prefers not to directly handle such messy details, and outsource their credit card application to Google. So far, so good - I got redirected to Google Checkout. Ok, I start filling in my personal data, until...

WTF? and yes, I do mean it. WTF?
I live, as many of you know, in a little country called Mexico. No, it does not appear on many world atlases. It's so very small, only slightly below two million square kilometers, that it's easily overlookable. Also, only a hundred million people live there - Not much. No, the 25,000,000 people that live together with me in Mexico City won't feel left out at all - We are used to it. But come on - In the listing I see our alphabetically neighouring countries (Malta, Mauritius, Moldova, Monaco)... Why did they get listed and we didn't? Of course, I tried editing the form data and substituting Moldova's MD for our dear MX, to no avail - We are not only off the map in their lists, but also in the database - and there are some integrity checks. Does somebody know which way should I whine in order to get the Google folks to fix this? :(

Version 3.14 of the CoPL released

As I've posted before, I recently read Lawrence Rosen's Open Source Licensing Software Freedom and Intellectual Property Law.

Well, today I woke up thinking about strengths and weaknesses in th different Free Software licenses, and I decided to add my grain to the world of license proliferation.

Got my Debconf tickets!

And, while on my way there, I'll get to visit my family in New York (and get to know a bit of the city, I hope) for a couple of days as well! :D Leaving Mexico in June 7th, three days in NY, travel to Edinburgh on June 10th (arriving early on the 11th), and head back home on the 24th. Yay! BTW, attempting to save some money and the pollution caused by air travel, I asked Google for how to drive from New York to Edinburgh. It looks clear and easy, but in the end I settled for air travel. Specially for the estimated travel time (about 29 days 17 hours)... Oh, and item 23 slightly worries me: Swim across the Atlantic Ocean: 3,462 mi.

It is no news that Richard Stallman spent some days recently in Cuba, and not precisely on vacation - He was quite active. But no, not only on politics: Also artistically. Yes, I do think he has to work a bit on his voice, but... Guantanamero surely deserves being listened to. Good Cuban musicians and all. Oh, and of course: The credits.

La Jornada vs. Debian

Submitted by gwolf on Tue, 02/06/2007 - 10:51
One of the leading newspapers in Mexico, often associated with its left-wing ideology (and, I don't think it's a coincidence, my personal favorite newspaper) published today this cartoon: So, dear Rocha... Are you implying that many past and present Debian releases are identifiable with the corrupt Mexican government? Our de facto president is like our first official release, Buzz (1.1)? Does Rex (1.2) properly represent the worst of the PRInosauric regime? Is Hamm (2.0) a good symbol for our whole political class? Woody (3.0), the first release I had the opportunity to work on while still being in NM, is like our sadly unforgettable ex-president Fox? Does our current stable release Sarge (3.1) equal to the repression that Chiapas, Atenco, Oaxaca, Michoacán and others have suffered? This cartoon made me sad, really sad. </jokingly>

Those who owned the Bible

Submitted by gwolf on Fri, 01/12/2007 - 17:40
I came across a very nice story by Leonel Rubio (Leonel, please correct me if I'm misattributing this to you), licensed under the Creative Commons license. It's in Spanish, but quite worth a read - Aquellos que Poseían la Biblia (Those who owned the Bible). It starts with the supposition that Disney, at the end of the ever-recurring cycle where they ask the US Congress to extend the duration of copyright (so that Mickey and Donald don't fall into the public domain), they push boldly for a new record: Not just 20 more years, but 500. Of course, this would be easily torn apart in little pieces in the laxest of law courts, but still, a nice read :) Thanks, Leonel! :D
