You are scaring away much more than that.
I just came across an invitation for BugCon 2012.
BugCon is a Mexican conference devoted to computer security — I cannot comment on its level or value because, although it's a topic that has long interested me, I must recognize each day I feel less of an expert, nowadays finding myself at the level of a "sysadmin who tries not to be too dumb for his own job security". Oh, and also because it would be completely off-topic for this post.
If you look at Vendetta's (the main organizer) blog post, it will probably give you the impression that the conference is just an excuse for the afterparty: Lets go see some b00bs! Do you think your fellow female hackers will have any interest in joining a bunch of sex-starved, hormone-infested teenagers who only want to pwn a website and grab more pr0n? Do you think females will feel welcome (or even mildly safe) between you? I would not think so. And I also think you are alienating any professional who might have any interest in joining your community, be it as a member, as a mentor, or whatnot.
I cannot right now do a coherent post on this topic, but I can reference you to what I have seen (and read) over the last almost 10 years, when the issue was first brought up to our attention. I am very glad to see that, at least in the Free Software area, there has been a real change of mindset. I hope you are in time to think about it and rectify.
Oh, and not the description of an incident, but a very interesting and thoughtful take on this: [pdf] Interesting analysis by Hannah Wallach on the numbers and motivations of women in Free Software groups. I don't know if Hannah has published this in article form, but many interesting points can be understood by looking at the presentation.
My good friend Vendetta: I don't mean this post (longer than what I originally intended) as a way to say you and the conference you are organizing for the third year (IIRC) already is unprofessional or targetted to pimply teenagers. I know the work you have put in it. I hope you see the points I'm trying to drive — You are of course free to have whatever afterparty you have. But, if as the main organizer, you are giving the images of nice chicks at Hooters more weight and relevance than to the conference itself... you are doing yourself a disservice. I hope you can rectify it, and make BugCon attractive to hacker women as well.

Every year, on January 1st, new material ceases to be protected by copyright and enters the public domain. This means, every year, more knowledge, literature, paintings, music, movies and a long etcetera becomes collective property, instead of being artificially held by the current holders of their rights.
As this image shows (source: http://publicdomainday.org/node/39 ), I have the honor(?) to live in the country with the longest copyright protection term in the world. Copyright in Mexico does not only last for 100 years — It lasts for the natural life of the author plus 100 years. This means that the popular corridos that tell the stories of the 1910 revolution are still not in the public domain. La sucesión presidencial, the book which Francisco I. Madero wrote to justify that a peaceful political change was needed for the 1910 elections, will not enter the public domain until 2014 (president Madero was killed during 1913). Does it make any sense to kidnap cultural, political or artistic works for over a century?
Not only that: Material that is legally sold as public domain in other countries is illegal in ours. Take as an example the recordings of Enrico Carusso, the great Italian tenor who died in 1921. Over 15 years ago, I bought a couple of CDs with his recordings (even if the sources were quite low-quality, as they had been copied over from wax cylinders to magnetic tapes to optical media). I bought them surprisingly cheap, as they were genuine public domain. But they are still protected in my country. That means, I ilegally have some stolen(!) works of art which I lawfully bought outside my country.
Copyright law needs to be revised to match reality. Technological advances have strongly changed reality since 1717's promulgation of the first copyright laws. The solution is not to extend the terms, but to rethink the whole process.
(yes, this rant was mainly made as an excuse for me to copy this image and put it in a location I can easily refer to later. But I hope it is interesting to you!)

I came to Argentina with my girlfriend to visit her family and friends, and to spend here some disconnected days during my winter^Wsummer vacations. And so it was, we had some very nice, relaxing days, with everything running smooth and with infrequent but enough sessions of mail access to withstand the disconnection without pain.
Of course, I didn't anticipate that the Network Operations Center of my university would break my institute's connectivity while performing their planned maintenance on December 23. After some days, I was able to talk with one person in the university, but connectivity was not restored. Nobody with knowledge to look at the firewall's screen is available.
So, as of today (happy new year 2012!), I have been mail-less for over a week. I will be back in my office soon now, so I'll get mail connectivity within the upcoming week.
Meanwhile, everybody who mailed me for any reason (job, Debian, holiday greetings, whatever)... Well, I'm sad to tell you that the mails were lost. But worry not, I will act as if nothing like that happened and I received all of your best wishes.

I recently started getting mails from email@example.com. Usually, a mail from no-reply@whatever is enough to make me believe that the admins of said whatever are clueless regarding what e-mail means and how should it work. And in this case, it really amazes me — If I get an invite to Diaspora*, right, I should not pester a hypothetical firstname.lastname@example.org to get me off his list, but I should be able to reply to the person mailing me — Maybe requesting extra details on what he is inviting me to, or allowing me to tell him why I'm not interested. But yes, Diaspora* has fallen to the ease of requiring me to join their network to be able to communicate back with the "friend" who invited me.
Some of the (three?) readers of this site might not be familiar with the Diaspora* project. It is a free reimplementation (as far as I know) of something similar to Facebook — Free not only in the sense that it runs free software, but also because it is federated — Your data will not belong to a specific company (that is, you are not the value object they sell and make money with), but you can choose and switch (or become) the provider for your information. A very interesting proposal, socially and technically.
I find that a gross violation of netiquette. I should be able to reply to the mail - Even if in this case it were to (and sorry – As you are spreading my name/mail, you will excuse me if I spread your name ;-) ) email@example.com. Such an (fictional FWIW) address would allow for mail to reach back the submitter by the same medium it was sent, without allowing open spamming into the network.
Now, what prompted me to write this mail (just before adding firstname.lastname@example.org to my blacklist) is the message I got (in an ugly HTML-only mail which erroneously promised to be text/plain, sigh...) is that Fernando sent me as the inviting message, «So, at least are you going to give Diaspora a chance?»
The answer is: No..
But not because of being a fundamentalist. Right, I am among what many people qualify as Free Software zealots, but many of my choices (as this one is) is in no way related to the software's freeness. I use non-free Web services, as much as many of you do. Yes, I tend to use them less, rather than more (as the tendency goes).
But the main reason I don't use Twitter is the same reason I don't use Identi.ca, its free counterpart — And the reason I'm not interested in Facebook is the same reason I will not join Diaspora* — Because I lack time for yet another stream of activity, of information, of things to do and think about.
Yes, even if I care about you and I want to follow what's going on in your life: The best way to do it is to sit over a cup of coffee, or have some dinner, or to meet once a year in the most amazing conference ever. Or we can be part of distributed projects together, and we will really interact lots. Or you can write a blog! I do follow the blogs of many of my friends (plus several planets), even if they have fallen out of fashion — A blog post pulls me to read it as it is a unit of information, not too much depending on context (a problem when I read somebody's Twitter/Identica lines: You have to hunt a lot of conversations to understand what's going on), gives a true dump of (at least one aspect of) your state of (mind|life|work), and is a referenceable unit I can forward to other people, or quote if needed.
So, yes, I might look old-fashioned, clinging to the tools of the last-decade for my Social Web presence. I will never be a Social Media Expert. I accept it — But please, don't think it is a Stallmanesque posture from me. It is just that of a person who can lose too much time, and needs to get some work done in the meantime.
(oh, of course: Blog posts also don't have to make much sense or be logically complete. But at least they allow me to post a full argument!)

This is an update to my last post regarding the «Construcción Colaborativa del Conocimiento» book.
But holding a printed book in your hands is just a different experience, isn't it? :-) Anyway, I said I would give here an update on how to get your hands on it. The main venue would be through my University's e-store. I recommend it to anybody interested in buying the book in Mexico. The book's list price is MX$300 (around US$27), but it is currently sold at half price — I don't know how long will that price be offered.
On the other hand, we also uploaded it to the lulu.com self-publishing service. Of course, given I have not seen the printed results, I cannot assure you the resulting product will be of the same quality as the one we got here, but I have a couple of books I have bought at lulu, and their quality is quite acceptable. So, you can also buy it from lulu.com. Note the 20% discount it shows will be permanent — That's what I would get as an author, a payment I decided to forefit given we are 11 authors and it would be unfair to collect it all myself. So, the price at lulu.com is US$12.64 plus shipping — Very similar to the price at UNAM.

Last Friday, after two years worth of work, I finally got the first box of books for the Construcción Colaborativa del Conocimiento (Collaborative Knowledge Construction) project I worked on as a coordinator together with Alejandro Miranda (pooka), and together with a large group of 11 authors:
Translating over from the back cover text (and this is just a quick translation from me — It reads better in Spanish ;-) ):
We will soon have the book ready in IIEc's e-store (which is mostly meant for national requests). I am also uploading the book to the lulu.com self-publishing service, and we are working on a epub-like edition. Right now it is still not available, but it should be there in some days. I will keep you posted.
Meanwhile, the full contents can be read online at http://seminario.edusol.info/seco3

There's something brewing, moving in Jalisco (a state in Mexico's West, where our second largest city, Guadalajara, is located). And it seems we have an opportunity to participate, hopefully to be taken into account for the future.
Ten days ago, I was contacted by phone by the staff of UDG Noticias, for an interview on the Universidad de Guadalajara radio station. The topic? Electronic voting. If you are interested in what I said there, you can get the interview from my webpage.
I held some e-mail contact with the interviewer, and during the past few days, he sent me some links to notes in the La Jornada de Jalisco newspaper, and asked for my opinion on them: On September 23, a fellow UNAM researcher, César Astudillo, claims the experience in three municipalities in Jalisco prove that e-voting is viable in the state, and today (September 26), third generation of an electronic booth is appearingly invulnerable.
Of course, I don't agree with the arguments presented (and I'll reproduce the mails I sent to UDG Noticias about it before my second interview just below — They are in Spanish, though). However, what I liked here is that it does feel like a dialogue. Their successive texts seem to answer to my questioning.
So, even though I cannot yet claim this is a real dialogue (it would be much better to be able to sit down face to face and have a fluid conversation), it feels very nice to actually be listened to from the other side!
My answer to the first note:
El tema de las urnas electrónicas sigue dando de qué hablar por acá en Jalisco... nosotros en Medios UDG hemos presentado distintas voces como la del Dr. Gabriel Corona Armenta, que está a favor del voto electrónico, del Dr. Luis Antonio Sobrado, magistrado presidente del tribunal supremo de elecciones de Costa Rica, quien nos habló sobre los 20 MDD que les cuesta implementar el sistema por lo que no lo han logrado hasta el momento, pudimos hablar hasta argentina con Federico Heinz y su rotunda oposición al voto electrónico y por supuesto la entrevista que le realizamos a usted.
And to September 26th:

Patrick tells about his experience moving from LVM to RAID.Now, why do this? I have two machines set up with LVM-based mirroring, and they work like a charm - I even think they work with better flexibility than setting it up in a RAID-controlled way, as each of the partitions in a volume group can be easily set to use (or stop using) the mirroring independently, and the requisite of having similar devices (regarding size) also disappears. Of course, this flexibility allows you to do very stupid things (such as setting up a mirror on two areas of the same rotational device - Good for toying around, but of course, never to be considered for production). And the ability to online grow and shrink partitions is just great.
So, Patrick, fellow readers, dear lazyweb, why would you prefer LVM-based mirroring to a RAID alternative? Or the other way around?

After many years of successfully dodging doing any serious programming in PHP, I had to get my feet wet with PHP for my RL job: I was requested to develop a simple but non-trivial module for our Institute's Drupal-based webpage.
It basically meant two and a half weeks devoted to head-scratching: I had read the very good John van Dyk's Pro Drupal Development book, and knew it would be an important resource were I to face writing a module or work on a theme beyond the most basic stuff… So I checked it out of the library, and started basically writing something similar to my good and trusty Perl code. After all, PHP seems quite similar to Perl, although forcing you to write more for no gain (i.e. requiring an array() declaration whenever you want to store more than one value together) or lacking important and useful constructs (not having a sane way to prepare a SQL statement for multiple executions with different parameters — Yes, there are DB access methods that do provide it, but Drupal 6 does not use them).
Anyway, book in hand, I started understanding while implementing (which is way different than just reading the book, right?) Drupal's notions. I cannot say I like them, but it's… ahem… doable.
Now, I hit a problem twice. I chose to ignore it the first time, as it was a corner case I'd look into later on, but had to devote for hours of my attention later on. When designing the
But... No matter what I did, the first element in
It was not until after a severe amount of head-scratching I came across this jewel in the PHP online manual:
GRAH. Using a sane language for some time had made me forget about the problems of true/false sharing space with other meaningful values. So, yes, checking for inclusion of a value in an array in PHP this way should be compared with class-bound identity (that's what
Anyway… While arrays (which in PHP are any kind of list, be it keyed as a hash or consecutive as a traditional array) are such an usual construct in any language, please do take a look at PHP's array-handling API. Too long. Too complex. Too many corner cases.
I cannot but wonder what keeps PHP as a popular language. It hurts.

Cineast and Free Culture activist Nina Paley wrote some days ago a rantifesto on why the FSF has a double standard: Why are the Freedoms guaranteed for Free Software not guaranteed for Free Culture?, by not following its own very strict rules on software when it comes to culture as a whole. Her post was widely circulated, and got (at least) one reply by fellow Debian Developer Wouter Verhelst, largely agreeing with her, and an anti-rantifesto by Joe Brockmeier — Which was promptly answered again by Wouter with a very fun and inspired post, written from the right angle: From the viewpoint of a person who is both a programmer and a musician, and understands the concepts at hand.
I'd love to write a longer, better thought post — But I'm tired and frankly stressed by many things, so I am just echoing their very interesting discussion to other people who might want to read it.
I have been thinking and writing bits on that subject over the last couple of months. An example of that was the talk I gave at the Senate ~6 weeks ago. Following that talk, I wrote a short article for Revista Zócalo (a widely circulated magazine mainly dealing with Mexican politics and social issues) called simply Software libre, cultura libre (full text available, but in Spanish only — You can try reading an automated translation if it suits you). I wrote the article, mind you, with very limited time, and I'll be the first to recognize the prose was quite poor this time :(
Anyway — My point is that our nature is to share culture, to build it in a collaborative fashion, and having the Internet as a practically zero-cost, zero loss medium with which we can interchange our creativity with other like-minded people will naturally boost creativity. Free Software emerged before other Free Culture groups just because programmers had privileged access to Internet in the 80s and early 90s; as network access –and digital creation tools– have got to more people, it's just natural for all kinds of free culture to grow.
Software is just a form of knowledge. Code is just a notation for a certain kind of ideas, just as the mathematical or musical notations. I believe (and hope) it's just unavoidable for us all to eventually switch to a mainly free cultural creation system.

We are few weeks away from the start of DebConf11. Excitement runs high in Debian-land. The two most worthy weeks of the year, every year, loom close. Our Bosnian friends have done a great job of finding and defending an amazing proposal, and are now facing the hard work and permanent adrenaline levels of being in charge of the closest I have seen to a herd of (well-behaved but wild and untamable) cats.
I have organized DebConf in my country. It was hellish, but at the same time, it's one of my most cherished experiences. And I'm sure the same will be said by the leaders of each successive bid — It is one of the most rewarding experiences you can imagine.
Next year, DebConf will be held in tropical Managua, Nicaragua. But, where will we meet in 2013? Well, that depends on you, my dear reader! Do you want to work your ass off for Debian and have utter fun? Do you want to show and share your country with this huge family of developers? Start thinking about pushing for a DebConf13 bid!
Do you have to be at Banja Luka to propose your bid? No. You can proxy via somebody — I'd suggest to do it via somebody who knows the location you are suggesting, but basically, choose a friend that you trust that trusts you. Of course, you can participate in the presentation session via IRC.
Do you have to be a Debian Developer to propose a bid? No. For DebConf9, none of the Cáceres guys was a DD; for DebConf10, some of the people most involved from the local New Yorkers were not DDs. For DC11, none of our dear and overworked hosts in Bosnia are DDs. And for DC12, the Nicaraguan crew is also made from people interested in getting closer to the Debian project, but not DDs.
Do you have to decide now? No. This is just a call for a first presentation, but the decision regarding DC13 will be taken probably around March 2012. However, giving a nice presentation at DebConf helps a lot, gives you visibility, and will get the ball rolling.
Is there a geographical bias? Slight. So far, and since the second DebConf, we have kept the tradition not to repeat continents on two successive DebConfs. This is not a hard condition, however!
What do you need to start thinking about? Go visit our prospective location checklist at http://wiki.debconf.org/wiki/LocationCheckList. You can also look at what other teams have historically presented. Finally, I just learnt about the existence of http://wiki.debconf.org/wiki/DebConf13 — Register there, even if you are just in the early phases of finding data.
We will be holding a DebConf13 bids presentation session, most probably (the schedule is close to being presented officially!) on 30-07-2011, at 17:00.

Umh, so Google created yet-another-beta-service with yet-another-invite-only stage. Whee! And this time they choose a name yet more stupid to their previous attempts (Wave, Buzz — now it's simply Google+).
And yes, some of my friends have mailed me invites (or offered them to me by chat) so I can join the fun and love, and lose the few free time I still have.
Guys, I care about you. I even love you all! But no, I don't care the least for so-called-social-network invites. I am quite a mess managing my time as it stands.
And I cannot reply this to you in person, as Google+ sends mails with a very helpful sender (email@example.com or variations of it), I have just added this to my .procmailrc:
What does this mean in human? That instead of manually ignoring your invitations and feeling bad about not answering to you, dear friends, I'll leave that job to my computer. I will not receive any Google+ invites.
Just as I don't receive Twitter and Facebook spam, FWIW.
Thanks for thinking about me!

Second speaker at today'sseminar,Vladimir Mojica. He is talking about th legal backing for DRM and TPM as well as laws against circumvention. He quotes USA's DMCA as one of the most complete, advanced and forward-minded laws,inviting the audience to push for such a law here.
I hope he gets to my (written)question, as today is a very important day in this regard: The Senate has requested the presidency to reject signing the ACTA treaty!
Very good news, in a document very well made, in a precise, legal and coherent(!) way.

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.
