Excuse me in advance for any typos. itting in a dark room and posting with a Kindle has its down sides.
I have been participating for about 1.5 years on a seminar about the copyright in the ediyorial ambit. This year, the focus is on digital media.
Today the first speaker is Dr. Kyoshi Tsuru, General Director of BSA Mexico. He is talking about the beauties and advantages of DRM and TPM. It was interesting to hear how he began by saying how people are afraid of nice, good, protective measures and call it with derogatoey, morally charged ways:Specifically about "self-utelage"measures. It is interesting t hear him in the role I often speak eg. by repeating that piracy is a derogatory,morally charged term for "making illegal copies"
Fun to hear how he defends that mainly academicians are disconnected from the real world...
Reading revolutions: Online digital text and implications for reading in academe — A (very informal) review
Submitted by gwolf on Fri, 06/10/2011 - 16:50
It's been a long time since I last took some time to read First Monday — A great online publication, if you are not familiar with it, that I would categorize (and no, I'm not probably well-informed in it to be authoritative) as dealing with social, psychological aspects of the cultural shifts the online world has brought upon us (often dealing with topics related to Free Software communities, the reason I first met the publication). Firstmonday is an Open Access champion from early on. It follows an approachable but academic format (this means, it is peer-reviewed, its articles give extensive lists of references, and the articles are not the short reads we have got used to finding on the net, but, quoting from their audience profile, English is not the first language of many First Monday readers; A large percentage of First Monday readers are not a part of academia; Cultures, educational backgrounds, and fields of study vary greatly among First Monday readers.) This means, it's at least a great publication for me to follow :)
Anyway — After a long time not following it, I have just read Reading revolutions: Online digital text and implications for reading in academe, by Barry W. Cull; First Monday, Volume 16, Number 6 - 6 June 2011 Nice, interesting read. As I was planning on telling about the article to a couple of friends more into the subjects than myself, I'll comment+quote some bits on it. Before going any further: The article makes several references to Maryanne Wolf. No relation to her — I'm not lulling my (two? are you both still reading?) readers towards her work ;-)
The article talks about the differences –social, even dips into some physiological aspects– that the activity of reading is sustaining due to the shift from an activity done mainly from books (or other similar printed material) to the computer screen. Of course, we all know from our own experience many of the basic traits — Shorter attention spans, a different reading pattern (skimming instead of reading; browsing through several related items instead of in-depth reading a single text as a knowledge unit).
The article begins with an overview of reading and humankind. Cull quotes Maryanne Wolf's phrase, «despite the fact that it took our ancestors about 2,000 years to develop an alphabetic code, children are regularly expected to crack this code in about 2,000 days». An interesting point I never thaught of is the start of reading as a purely mental activity, detaching reason from verbalization, ~1200 years ago:
One last important point in this older history, that I'm quoting because I know I'll need the reference later on for one of my texts is about reading as a social activity — Yes, also related to the quietness I just mentioned:
After this introduction (obviously one of the most interesting parts to me), Cull gives numbers showing how reading is evolving (in the USA and Canada), and quotes some prediction on how the future will end up adapting. Of course, I live in a place with a very different society, so I cannot comment much. Then he confronts some studies regarding specifically leisure reading, as it is a much more trustable factor than just literacy (in a world as highly literate as ours is, many people only read when they have to — and have never or very seldom experienced the pleasure of reading just for the sake of it), bringing into the discussion the Internet (and computers in general) usage patterns.
I found also very interesting the next section, regarding the pattern changes many libraries are facing now, specially academic/research-oriented libraries:
And yes, doing some work with our Institute's library, I can confirm this trend.
About e-books: I have got quite into that topic since the Kindle won my heart (and my money!) half a year ago. The little device completly changed my reading habits, I have read lots more since I carry it. And yes, I have never considered a full tablet-like device — The article talks long about the difference, about the disadvantage that multitasking means to the human brain (oh, do I suffer from it!) I liked this snippet, quoting Steve Jobs a couple of years ago, regarding an Apple e-book reader question:
The issue for me is, I do enjoy reading, but I am an information addict. I know that if I have parallel information flows, my attention will surely dilute between them. Of course, as I read this article on-screen, it was hard for me to take the needed discipline not to be distracted by IMs or IRC highlights during the whole reading (which was also as an excercise for myself ;-) ). I am surprised to see this on student preferences (and even more surprised to see this data comes from my university):
As we approach the end, it talks about another important topics I have often tried (and often failed) to communicate to my users: That of paratext, the meaning of the different texts, covers, items, layouts, etc. that are not part of the text itself but do shape the way we face it. To some of us, this seems obvious. To others, it is so hard to understand…
It closes with two more topics I will refer to. One is the permanent connectivity. All the time, more people are connected virtually all of their waking time. This affects not only learning habits but priorities. Will this near–constant access to information interfere with students’ desire to comprehend and remember information, necessary to the educational process of turning it into knowledge? Author and university business school lecturer Don Tapscott recently suggested that students “might not have to stress about the details — those you can check”
Finally, regarding the continuity and ellaboration found in texts that are each time more common — He quotes Maryanne Wolf:
As you can see, not only this post is meant to tell my couple-of-interested-friends to read the article, but it's mainly meant as a mental placeholder for myself. I will be surely refering to some of these items.

I was invited to be part of one of the panels to be present this Thursday (June 2) in a forum that promises to be interesting. The forum is organized by the Science and Technology comission of the Senate of the Republic (of Mexico ;-) ), Universidad Autónoma Metropolitana and Mozilla México. The day will be opened by Sen. Francisco Javier Castellón Fonseca and Richard Stallman; starting at 10:00, we will have thematic panels on:
The full program (as well as details of interest of those that can physically attend) is attached to this post.
I am looking forward to this forum. Not only it is a good opportunity to get our work known in one of those places where it matters, but it's also being organized by several interesting people I'm sure will have something interesting to contribute. And of course, we lacked time to build a better, more complete and more coherent proposal — but there is a good probability we will have further such contacts.
You might find interesting to read on the list we have been discussing; subscription seems to be open (although access to the archives is not — Maybe it will be later on? In any case, I'm saving a mbox ;-) )

While swearing at my bank's automated phone attention system, I was thinking that –taking advantage in the fact they already usually say that "the call will be recorded to improve service quality"– call center operators/programmers should record all user activity and, just for laughs, play back the grumbles angry users shout at the system. Of course, at random intervals, on loudspeakers, over the crowded call centers.
Oh, they do it already?

Today we had a very interesting demonstration. People who know me for some time know I like to be a part of demonstrations, adding my voice to the people. And even though I know most demonstrations, as massive as they might be, have no real and tangible effect... Well, I try to be there.
Today we had a large demonstration in Mexico City of people angry with the government's tactics on the war on drugs — Have you been to Mexico before 2007? You will remember we have always had our problems, but violence was basically limited to keeping an eye open, not flashing your money/jewels, and not looking too touristy. We were, all in all, a quiet country — Known even as "the country where nothing happens, even if it happens".
Five years later, a good portion of the country lives really in war-like conditions, and close to 45,000 people have been killed. At some point about a year ago (where the body count was at ~22,000), our oh-so-bright de-facto president said that "only" 10% of them were civilians. If that is still the case, and if proportions are held, we can now talk about ~4,500 people killed just because they were there — Oh, but remember the country is not at war, and death penalty has very long been abolished, so we cannot give the other 90% a different status. We have had over 45,000 killed people. That means at least ~200,000 torn lifes.
About six weeks ago, the cry from a father who lost his son started getting heard. And no, I do not want to talk about specific names or anything like that — It is just the voice-bearer of many people who are fed up. Four days ago, he and a group of people left Cuernavaca city on a caravan and walked to Mexico city. Yesterday evening they arrived to the National University (UNAM), and were greeted by an amazing open-air concert: Mozart's Requiem.
Today, our day started very early. My mother wanted to help, as many more anonymous citizens did, so we started making and packing sandwiches and apples at ~5:30AM, delivered them to the camp where they were staying and grouping with other people, and came back home for our breakfast. Later, at around 9AM, as the demonstration started going by our house (we live a block from UNAM), my girlfriend, father and me started walking with them.
Why do I say this was a different demonstration than others I have been to?
Will this change anything? I doubt it. I am happy that for the first time, the de-facto president (remember a large percentage of Mexicans still believe he lost the presidential election, and it was only due to his lack of legitimacy that he pushed the army to the streets to start this war on drugs) is recognizing that this might not be the best strategy but it is the only one he has... People are still, despite what I saw many felt, very far from organized. And, yes, no short-term concrete proposals are made on how to stop the killing — I feel the population agrees that drugs should be legalized and regulated, that would at least shift the problem, reduce the direct violence (and money) related to it... But, of course, it is plainly not feasible with our current reality.
Anyway, after a 5hr walk today (and even after a nice nap and shower), I don't want to dig into hypotheses anymore. I just wanted to share about a very interesting and different experience I had the opportunity to be part of.

As others have started posting in Planet Debian, I'll do my part: Yesterday I finished booking our flights, so if everything goes as planned, Reg and me will be arriving to Zagreb (Croatia) at 21:30, Monday July 18, to take part of the 12th Debian development conference, DebConf11, in Banja Luka, Bosnia & Herzegovina!
Of course, reiterating this will never hurt: Do you want to support a global-scale, well-recognized, community-based Free Software project development? Be a sponsor for DebConf11!"

I took part in a occupational-health-related thread recently, and wrote a bit of my experience which might be helpful for my readers, many of them avid keyboard users, with usually ≥8hr of typing per day.
(…) I suffered not from RSI but from painful back aches. I started using standard keyboards in a different fashion, not putting so much stress on my wrists (and on the muscles connecting them to the rest of the body, of course): I exclusively use US keymaps (with some modifications to allow for proper Spanish input and ﬀŭₙṅý characters), but instead of making the middle row my fingers' home row, I type with the base position of my fingers in a V shape — Fingers resting on (approx.) w-e-f-v-spacebar and spacebar-m-l-;-]; the fingers doing most of the travelling are the index and middle, and with no straining for the little fingers to reach ` or backspace. On the other side, the most straining keys become Control and Shift, which requires closing the hands a bit too much, but are not that bad. My way does induce some new kind of stress, as my arms also have to move to reach 6 and 7, but it... Works for me™.
It looks weird and is somewhat strange to get used to, but I must say it has worked great for me. I work this way on regular and laptop keyboards, even on my netbook's noticeably smaller one.

Ok, so finally it is official!
If you are curious on the decision process: We held it over two IRC channels — The moderated #debconf-team channel, where only the five members of the decision committee (Marga Manterola, Andrew McMillan, Jeremiah Foster, Holger Levsen, Moray Allan) and two members from each of the bids (Marco Túlio Gontijo e Silva and Rafael Cunha de Almeida from Brazil; Leonardo Gómez and Eduardo Rosales from Nicaragua) had voices, and the open #dc12-discuss channel where we had an open discussion. Of course, you can get the full conversation logs in those links.
I have to thank and congratulate the Brazilian team as they did a great work... The decision was very tight. It was so tight, in fact, that towards the end of the winning all of the committee members were too shy to state the results - so I kidnapped the process by announcing the winner ;-) (I hope that does not cast a shadow of illegitimacy over it)
And, very much worth noting, both teams were also very professional: In previous years, we have seen such decisions degenerate into personal attacks and very ugly situations. That has always been painful and unfortunate. And although the Brazilians will not be able to go celebrate tonight, the decision was received with civility, knowing it was a decision among equals, and a decision well carried out.
Well, that's it — I am very much looking forward for that peculiar two weeks when the whole Debian family meets, this year to be held in Banja Luka, Bosnia-Herzegovina, and I am very eager towards meeting in 2012 in Managua, Nicaragua!

Some years ago, I faced a 900 word limit for the first time. My question to the editor: Can I write the column in German?
Submitted by gwolf on Mon, 03/21/2011 - 20:24
People enjoy writing with Twitter's arbitrary 140 character limit. I suffer when I have to write a column with a 900 word limit. Limits suck.

Quite probably, the best thing got for myself during the last year was my Kindle. I just love it! It has changed the way I interact with knowledge, and saved me from hours of boredom.
But it has also taught me the value of scribbling along the book pages and of underlining passages. Yes, I hold a deep regard for my regular (paper) books, and I never scribble on them, not even on text books. In any case, I can scribble on a post-it or something like that.
Still, when you underline or comment on a passage in the Kindle, what can you do with your annotation? Well, not much. Annotations (called clippings in Kindlespeak) are stored on an easily accessible My Clippings.txt text file, very easy to parse and work with.
So, I devoted yesterday evening to coming up with a first prototype of an app that I think can be very useful if you use clippings extensively: It displays each clipping with its base information separately, allows you to filter on the specific book to which each clipping is related as well as on the clipping type.
So, if it interests you, clone it away from github!
Written in Ruby, Gtk (Glade). No further libraries are (currently?) needed. The code is far from beautiful, but is a first stab towards functionality.
Any comments welcome!

Yes, I have not used this kind of outfit for over 20 years. And I hope it will be 20 more years before I do it again. But today, I was seen like this in public. Why?
Well, I won't explain the whole background yet again — I did it a bit over a month ago in this same space. Much much in short, I never attended university, so –after many years of working without any formal validation for my knowledge– I followed the CENEVAL Acuerdo 286 procedure to get a "Software Engineering" title and the corresponding cédula profesional.
Today I did the last portion of this procedure: Presenting an oral exam, defending the work I developed. Not precisely a thesis, but you can see it as an equivalent.
One of the requisites was to go on formal attire — Of course, I have some beautiful shirts I am very fond of, but I didn't want to risk it to such a detail, so I asked my friend and almost-neighbour Miguel Barajas to lend me the needed bits of clothing, and presented the exam.
Was it easy? No, not by a long shot. Did I pass? Yes!
Now, back to work!

As you know, I very often advocate using the bycicle as the main means of transportation in Mexico City. The city is very apt for biking through it, and contrary to the fears of mostly everybody, the city is neither aggressive nor as dangerous as people say.
However, I have seen cyclists which seem to be looking for the best ways to be hit by a car, or to hit a pedestrian.
Many cyclists assume they are a special case of pedestrians, and zig-zag as they please between the road and the walkway, or just stay in the walkway. That is dangerous, both to pedestrians and to themselves. You might find children, elderly or motion-challenged people on your way. Also, not only will pedestrians only expect other people in the walkway, moving at their pace or slightly more, but cars will also not expect somebody moving at 10-20Km/h. A car driver pulling out of his garage, or crossing a street, will not have enough warning when he sees you, and you are very likely to end up in an accident.
Since ~5 years ago, Mexico City is growing a grid of Metrobús and confined trolebús cero emisiones (trolleybus) lanes. Many cyclists use those lanes — That is VERY dangerous. Public transport vehicles are large, have a lot of inertia, and will take longer to react to finding you ahead of them. Besides, they can go way faster than a regular bike (~60Km/h for metrobús, ~40Km/h for trolebús), and have to stop every couple of blocks. So, you will be uncomfortable if trailing them, and you will be a liability to ~100 people if you go ahead of them. Besides, it is illegal to drive in the confined lanes if you are not a public, semimassive transport vehicle!
Surprisingly many people have argued they prefer riding their bicycles against the traffic — I think they prefer staring at Death into its blue, glowing eyes (or into its long, thin whiskers)... By far, most cars that hit a bicycle do so from the side, when crossing a road. And if you arrive at a crossing from the wrong way, the way a driver does not expect you, don't expect the driver to be aware of you. Also, in the much less likely event of a car running into you, would it be better to be hit at 80Km/h (60Km/h of the car plus 20Km/h of your own speed on a full frontal crash), or at 40Km/h (substracting instead of adding)? Yes, some people say that looking at the car will allow you to maneuver – How far in advance would you know a car coming from the front will hit you? One second? That's 22 meters at 80Km/h (again, if you realize the 60Km/h car is heading straight to you, at 20Km/h). Too short notice for you to do anything — Any maneuver will most likely end in an accident. And the driver would not be so much to blame, as he would not be anticipating you riding against the traffic.
Make sure you get seen. By night, always use proper lights (red on the back, white on the front, and reflective material to the sides). Day or night, wear bright, reflective clothes (or over-clothes material). Act in a predictable fashion. Remember you are riding a vehicle and are subject to the same rules any driver is — A cyclist is not exempt from driving correctly! Do not jump red lights. Never ride on the walkway. Do your best to enjoy the ride.
And ride. Yes, ride, take the streets, enjoy the streets. But don't attempt to drive the traffic out of it — The streets belong to us all, and we can all share them.
PS — I also saw this note in the same paper: Sunday Rides in "Campo Militar Número Uno". The main military field was open as a park this weekend! I have to make sure it is regularly open — I am definitively going there!

Hrmh... I am listening to a local news radio station. Of course, what I am about to write lacks information and insight — but it follows a conversation I have had with several groups of friends.
Our de-facto president has decreed that the tuition for private schools will be deducted from the Impuesto sobre la renta (revenue/profit tax) up to a given tuition level (IIRC up to MX$2000 a month per child per school). The interviewed subsecretary said they expect this deduction will reach MX$13,000 million, around US$1,000 million. This is, about a third of what is assigned to the National University (UNAM).
At a first sight, this sounds good. However, I just thought about a discussion I have had with many friends. This money the government will hand back to the taxpayers has to be cut from somewhere (after all, we are not in a country with huge superavit or anything like that).
Why does this sound unfair ot me? Because it benefits the few in perjudice of the many. I did a quick search, and found this work based on numbers published by INEGI ten years ago: According to the last table, the money spent on private education was between 5% and 10% of that spent on public education — Of course, it is almost impossible to infer the number of students from this alone. I know I could find authoritative data on this regard by searching a bit more, but after all I don't want to spend all (work!) evening on a blog post unless it creates some discussion. Lets say, just for the sake of the exercise, that this means that ~3% of the country's students learn in a private school.
In Mexico, the quality of the basic public education (primary/secondary, ages 6 to 18) has fallen hugely in the last decades. Even when I was to school (but not when my parents), the first subjective sign that a family had broken the low-income barrier is that they were finally able to send their children to private schools. Because, no matter how bad they are, public schools are perceived to be worse. Of course, I was among the "lucky" ones to be in a private school. Higher education (universitary level) is still way better ranged.
Anyway... I want to get this post over with. Why do I oppose this subsidies/tax devolution? Because it will lead to widen the difference between private and public education. And because it will be benefical only for medium-high and high classes — People who are formaly employed (as I am) do not present a tax declaration, so we won't get any deductions. Between ⅓ and ½ of the country's economically active population work informally (from selling in the street to covering up huge transactions in large locals). Most of the population don't (directly) pay "impuesto sobre la renta", and will not get the benefit of this subsidy.
This money has to be taken from other sources in order to be given to private education. If the government wants to improve the education for everybody, why not assign it to the public sector? To specific areas in the public sector, if they don't want to hand it over to the (yes, very, incredibly) corrupt SNTE (National Union of Education Workers)?

For those of you who follow me through anything other than Planet Debian (who will surely tolerate this repetition):
Interesting but frightful things are happening in North African countries. We saw what happened in Tunisia some days ago. Now, Egypt is a way larger, way more populous... And, dare I say, way more important country. Also, it is a country which borders Israel, where I lived in for ~18 months, and to which –although I am today unaffiliated– is very important for me. And what happens in Egypt will surely shape the whole mid-East.
So, here goes a copy of Mohammed Sameer's post — Not just a link to it, as he might have to take it down. Of course, Mohammed, if you in any way think I should delete this, please please tell me, and I will comply immediately.
...From what I read from Israeli sources, what worries them –and many people around the world– is that, although Egypt is formally a democratic country, the ruling party has seen towards having basically no oposition — Besides the stubborn Islamic Brotherhood (very akin to Hamas). Now, the Islamic Brotherhood (as well as Hamas, and as well as most other Islamic regimes I know off, although I might be way mistaken) have got huge popular support because... They are true to their beliefs. In short, they are not corrupt — Something that cannot be said about many political organizations around the globe. They are true to their word. And although many of us shiver at thinking of their word getting more power... It is only the Egyptians who should have a say on who rules Egypt.
I honestly hope the Egyptian people get their long-owed self-determination. Of course, I hope Tunisians also get it, and not just a mirage of it. And every people, including us poor Mexicans who have neither had a chance to rule our destiny. And I hope it is a change for good, for tolerance, for peaceful coexistance with the neighbours, even if they are in many ways the rivals.
[Update] I just found out that, as expected, the news have reached Slashdot: Egypt shuts off all Internet access. I'm sure you will find lots of more information there.
