OK, I already bragged that our book on Operating Systems is finally printed and has, thus, been formally published.
What I had not yet mentioned is how we planned its physical distribution. Yes, it is available for sale at some UNAM libraries... But coming to UNAM is sadly an option only for people who are in Mexico City.
I have been quite busy, and was unable to come up with anything earlier, but I have finally finished setting up a decent although minimal web page for the book. In it, I mention the possible ways you can get your own printed copy of Fundamentos de sistemas operativos:
- If you are in Mexico, the advised way is to call or mail the library at Instituto de Investigaciones Económicas — (+52-55)5623-0080 or email@example.com.
They will ship the book (they would ship it overseas, but it'd be too expensive!) and are able to process electronic payment opetions.
The book printed at UNAM has substantive part of its pages printed in color, and let me tell you... It's worth it.
- If you are not in Mexico or you prefer not to deal with a human, you can buy the book from the on-demand printing service lulu.com.
For cost reasons, it is printed in black and white, but it is the same content (minus two typos ;-) ). Lulu.com is an international company, so they will get it shipped to you cheaper and faster — And I have requested the book to be made available to libraries such as Amazon and Barnes and Noble (and was told it should take a couple of weeks to have it ready there).
(and please report me any bugs you see!)
Today I was refered to the publication of an "agreement" signed by my university's Rector: The Agreement that establishes the General Guidelines for the Open Access Policy of Universidad Nacional Autónoma de México.
This is a document we have been waiting and pushing for throughout several years; I got involved in the Network of Digital Collections (Red de Acervos Digitales), RAD-UNAM back in 2011, and am honored to be its current coordinator, but this group has roots back in 2005. And, of course, by then several other people had been working on the topic without formal coordination.
Not only we are happy because the agreement explicitly mentions our group as one of The Venues for Open Access publishing and dissemination in UNAM. In its seventh point, it mentions:
In the matters of Open Access, academic entities and university dependencies have the following obligations:
VII. Promote and support the creation and maintenance of institutional repositories, as well as the deposit of the digital resources produced by its academic community, which should be incorporated into Red de Acervos Digitales de la UNAM
So... We have done a good job. And there will be surely more to follow!
I'm including here a copy of the agreement by itself (without the whole number of the Gaceta UNAM) because I will surely have to refer to it in the future.
Basically everybody who knows me is aware that, basically for the last two years, I have been writing a book on Operating Systems for use in my class — and, of course, in any similar class. Well, long story short, as of today:
What's that in my car trunk? Lets have a closer look.
Finally, Facultad de Ingeniería finished printing the book!
So... Well, some minor data points:
- The book is (and has been for some time already!) available online as a free download.
- If you want to derive from it or enhance future editions in any way, just clone it!.
- Want to get a physical copy? Great! It will soon (a week or so) be ready at both the Faculty's and the Institute's bookstores.
- But coming to UNAM is hard for you? Stay tuned. I have uploaded it to an on-demand printing service (Bubok), but its service is so dismally slow that I'll try it somewhere else. I'll keep you posted!
Anyway... Very happy here :D
A couple of months ago, I was invited to give the starting course for the Masters degree in Free Software in the Universidad Andina Simón Bolívar university. UASB is a multinational university, with campuses in (at least) Ecuador, Chile, Bolivia and Colombia; I was doubtful at first regarding the seriousness of this proposal and the viability of the program, but time made my doubts disappear.
Bolivia is going through an interesting process, as they have one of the strongest worded government mandates for migration to free software for the public administration in the next couple of years; this migration has prompted the interest of many professionals in the country. In particular, we have over 40 registered people for this Masters degree. Studying a Masters degree is a long-term commitment which signifies a big time investment, and although many of the student are quite new to the idea of free software, they are willing to spend this time (and money, as the university is privately owned and charges for its enrollment).
I gave this class together with Alejandro Miranda (a.k.a. @pooka), as we have a very good pair-teaching dynamics; we had already given many conferences together, but this is the first time we had the opportunity to share a whole course — and the experience was very good. We have read the students' logs, and many of them clearly agree with this.
I had to skip two of the (ten) lessons, as I travelled from Mexico to Argentina halfway through it (of course, we brought the babies to meet my wife's family and friends!), so we had also the honor of having Esteban Lima fill in for those sessions.
I am very happy and grateful that the University took care to record our presentations and intend to record and put online all of the classes; as we were the first in the program, there were some understandable hiccups and some sessions were lost, but most are available. Here they are, in case you are interested in refering to them:
|Topic||Video (my server)||Video (Youtube)|
|Introduction to free software||Watch||Watch|
|The effects of free software||Watch||Watch|
|Free software and open standards related to technologic soverignity||Watch (low)
|The free software ecosystem||Watch||Watch|
|Free software implementation in Bolivia||Watch||Watch|
|Introduction to intelectual property: Copyright, patents, trademarks, etc.||Watch||Watch|
|Who is "the community" and why do we speak about it?||Watch (low)
|Current status and challenges for the movement||Watch||Watch|
All in all: This was a great opportunity and a joy to do. I think the material we used and developed fit well what was expected from us, and we had fun giving somewhat heterodox readings on our movement.
[Update]: UASB uploaded some extra videos, with a much better quality! I added them to the table above, specifying (Low) or High whenever needed. Also, all classes are now available. Enjoy!
Today I feel more special than I have ever felt.
Or... Well, or something like that.
Thing is, there is no clear adjective for this — But I successfully finished my Specialization degree! Yes, believe it or not, today I can formally say I am Specialist in Informatic Security and Information Technologies (Especialista en Seguridad Informática y Tecnologías de la Información), as awarded by the Higher School of Electric and Mechanic Engineering (Escuela Superior de Ingeniería Mecánica y Eléctrica) of the National Polytechnical Institute (Instituto Politécnico Nacional).
In Mexico and most Latin American countries, degrees are usually incorporated to your name as if they were a nobiliary title. Thus, when graduating from Engineering studies (pre-graduate universitary level), I became "Ingeniero Gunnar Wolf". People graduating from further postgraduate programs get to introduce themselves as "Maestro Foobar Baz" or "Doctor Quux Noox". And yes, a Specialization is a small posgraduate program (I often say, the smallest possible posgraduate). And as a Specialist... What can I brag about? Can say I am Specially Gunnar Wolf? Or Special Gunnar Wolf? Nope. The honorific title for a Specialization is a pointer to null, and when casted into a char* it might corrupt your honor-recognizing function. So I'm still Ingeniero Gunnar Wolf, for information security reasons.
So that's the reason I am now enrolled in the Masters program. I hope to write an addenda to this message soonish (where soonish ≥ 18 months) saying I'm finally a Maestro.
As a sidenote, many people asked me: Why did I take on the specialization, which is a degree too small for most kinds of real work recognition? Because it's been around twenty years since I last attended a long-term scholar program as a student. And my dish is quite full with activities and responsabilities. I decided to take a short program, designed for 12 months (I graduated in 16, minus two months that the university was on strike... Quite good, I'd say ;-) ) to see how I fared on it, and only later jumping on the full version.
Because, yes, to advance my career at the university, I finally recognized and understood that I do need postgraduate studies.
Oh, and what kind of work did I do for this? Besides the classes I took, I wrote a thesis on a model for evaluating covert channels for establishing secure communications.
Guests in the Classroom: Felipe Esquivel (@felipeer) on the applications on parallelism, focusing on 3D animation
I love having guests give my classes :)
This time, we had Felipe Esquivel, a good friend who had been once before invited by me to the Faculty, about two years ago. And it was due time to invite him again!
Felipe knows his way around the different aspects of animation. For this class (2015-04-15), he explained how traditional ray-tracing techniques work, and showed clear evidences on the promises and limits of parallelism — Relating back to my subject and to academic rigor, he clearly shows the speed with which we face Amdahl's Law, which limits the efficiency of parallelization at a certain degree perprogram construct, counterpointed against Gustafson's law, where our problem will be able to be solved in better detail given more processing abilities (and will thus not hit Amdahl's hard ceiling).
Once again, on March 11 I had a great guest to save me some work and give a talk at my class! This time it was César Yáñez, and he talked about memory management algorithms, emphasizing on ARC.
Thanks a lot!
On November 14, as a great way to say goodbye to a semester, a good friend came to my class again to present a topic to the group; a good way to sum up the contents of this talk is "everything you ever wondered about persistent storage".
As people who follow my blog know, I like inviting my friends to present selected topics in my Operating Systems class. Many subjects will stick better if presented by more than a single viewpoint, and different experiences will surely enrich the group's learning.
So, here is Rolando Cedillo — A full gigabyte of him, spawning two hours (including two hiccups where my camera hit a per-file limit...).
Rolando is currently a RedHat Engineer, and in his long career, he has worked from so many trenches, it would be a crime not to have him! Of course, one day we should do a low-level hardware session with him, as his passion (and deep knowledge) for 8-bit arcades is beyond any other person I have met.
Last Wednesday I had the pleasure and honor to have a great guest again at my class: José María Serralde, talking about real time scheduling. I like inviting different people to present interesting topics to my students a couple of times each semester, and I was very happy to have Chema come again.
Chema is a professional musician (formally, a pianist, although he has far more skills than what a title would confer to him — Skills that go way beyond just music), and he had to learn the details on scheduling due to errors that appear when recording and performing.
The audio could use some cleaning, and my main camera (the only one that lasted for the whole duration) was by a long shot not professional grade, but the video works and is IMO quite interesting and well explained.
Two causally unrelated events which fit in together in the greater scheme of things ;-)
In some areas, the world is better aligning to what we have been seeking for many years. In some, of course, it is not.
In this case, today I found our article on the Network of Digital Repositories for our University, in the Revista Digital Universitaria [en línea] was published. We were invited to prepare an article on this topic because this month's magazine would be devoted to Open Access in Mexico and Latin America — This, because a law was recently passed that makes conditions much more interesting for the nonrestricted publication of academic research. Of course, there is still a long way to go, but this clearly is a step in the right direction.
On the other hand, after a long time of not looking in that direction (even though it's a lovely magazine), I found that this edition of FirstMonday takes as its main topic Napster, 15 years on: Rethinking digital music distribution.
I know that nonrestricted academic publishing via open access and nonauthorized music sharing via Napster are two very different topics. However, there is a continuous push and trend towards considering and accepting open licensing terms, and they are both points in the same struggle. An interesting data point to add is that, although many different free licenses have existed over time, Creative Commons (which gave a lot of visibility and made the discussion within the reach of many content creators) was created in 2001 — 13 years ago today, two years after Napster. And, yes, there are no absolute coincidences.
I got word via the Electronic Frontier Foundation about an act of injustice happening to a person for doing... Not only what I do day to day, but what I promote and believe to be right: Sharing academic articles.
Diego is a Colombian, working towards his Masters degree on conservation and biodiversity in Costa Rica. He is now facing up to eight years imprisonment for... Sharing a scholarly article he did not author on Scribd.
Many people lack the knowledge and skills to properly set up a venue to share their articles with people they know. Many people will hope for the best and expect academic publishers to be fundamentally good, not to send legal threats just for the simple, noncommercial act of sharing knowledge. Sharing knowledge is fundamental for science to grow, for knowledge to rise. Besides, most scholarly studies are funded by public money, and as the saying goes, they should benefit the public. And the public is everybody, is all of us.
And yes, if this sounds in any way like what drove Aaron Swartz to his sad suicide early this year... It is exactly the same thing. Thankfully (although, sadly, after the sad fact), thousands of people strongly stood on Aaron's side on that demand. Please sign the EFF petition to help Diego, share this, and try to spread the word on the real world needs for Open Access mandates for academics!
