ShareIt! on #JoinBiz10

 I have been selected to do the next monday a keynote (really, a 'lighting talk') on the #JoinBiz10, an entrepreneurship event where interesting IT projects can meet managers and MBAs and viceversa. Leets see if I can get some patrocinators for ShareIt!... :-D

And in other news, my networks teacher has accepted to use ShareIt! as final practice and has give me some guidance, and also I have just got to use XMPP instead of PubNub as handshake server. Please don't change the dial... :-P

T3chFest Keynote

Finally, after two weeks while they were editing it, I've just received the video of the T3chFest presentation :-D


As you can see, the keynote was really well, without failures and a lot of question at the end (in fact I was almost the only one that got questions :-P ) although the limited time :-D Unluckily, I only got a third position. The reason? "It's not enought commercial, but you should think about develop it as a research project".

Taking in account that I was hearthly confident that I would get to start a company from ShareIt! and how is the situation of research on Spain, at a first point I toke the comment really bad, but on a second chance I though, isn't this was I always wanted? :-) To be honest, I've always wanted to work on R&D on my own projects, only that I need to pay the bills. That's the reason why I think that finally I'll do my career thesis with ShareIt! and work on it as an research project after that on my spare time (although it would be better to find a filantropist that believe in it! :-P ). In the last days I have been thinking about some interesting concepts for the next version of ShareIt! and WebP2P becoming them in a more general and ambitious project, and they'll need some attention and love to became true... :-)

The longest journey: the movie

One thing that I forgot to mention on my previous post related about my last freaking awesome weekend was the fact that I have proves about it happened, so like they say in Facebook "if there's no picture it didn't happen", here it's the video about my WebRTC DataChannels & ShareIt! project I did the last friday in front of 75 persons on the RealTimeWeb conference (sorry, audio in spanish... Having only about three minutes you don't have too much time to think in english and you can only hope to talk as fast as possible... :-P).



If you can't be able to see the video you can download it on MP4 or WebM.

Just to say that althoug in the video it "doesn't work" later I investigated and was a bug of Chrome v25 unstable (obviusly... ¬¬) and just closing the tabs and openning them again it worked the second time (now I need a new video to show that it happened... :-P )

Slides are availables on the RealTimeWeb site and also the ShareIt! repository.

The longest journey

The last 72 hours have been one of the longest and most full-filled weekends I have had ever.

First of all, the friday I did my first wide-spread demo and presentation of ShareIt! (if we don't take in account the little one that I did some weeks ago for the Python Madrid guys) at the RealTimeWeb conference here at Madrid in front of 75 persons (the biggest public I have had in a presentation). In short: an awesome success :-D It was just a little and fast presentation because the organization run out of time and also I needed to go the the 3 Day Startup later, but the fact is that in less of 3 minutes I did the presentation, showed a demo, and the public exploded in ovations :-D (the fact that being the (almost?) only one in all the world working in some really awesome high-edge technology just because it's not ready yet would be the cause... :-P) Also, the fact that I got some propositions from the UPM teachers to work on their investigation projects related with WebRTC and they also gave me some good ideas to solve the signaling problem are some really great news too, by the way... :-P Keep listening... ;-)

But if this was not enough, as I have just say I needed to go the the 3DS so didn't be able to participate on the hackathon of the afternoon (with some iPad-mini as prices, just some kind of deviavious temptation after my Galaxy Tab I won on the CUSL two years ago with PirannaFS was stolen the last week... ¬¬). What to say about the 3DS? Crazy, period. It was about just like a small-sized CampusParty but without my sleep sack under the table. Some of the projects were really interesting and in fact I needed to flip a coin in the last moment just to select between two of them about were to work (maybe with some telekinetics since It was complementary to my Priorities project... :-P), and the fact is that in the last three days I have work more hours than in a normal job week and spend more energies than in a month :-P Add to this the fact about going to bed not before of 4 o'clock and waking-up at 8:00 to be early in the morning on the event (I didn't want to do it, by finally they convinced me to take some beers all the nights... :-P) and now you would understand why this morning I seems a brain-less zombie :-P The bad news is that it was a one-shoot, so I will not be able to use the experience and propose the next year a better project (I was thinking about a "producer for genious" company to take out all the burocrazy and mind-disturbing things and let "genious" to concentrate on their work in a similar way movies producers take in account all the boring details and let the movies directors to do the magic) so maybe this is something I would change about it... :-( In any case, if I can, I'll repeat the experience :-D

But on the personal area the best news would be that after four years working on the private sector and forced to "back to the basis" (no job, no money and just have part-time university classes and being full-time freaking with my geek personal projects :-P) I'm remembering why I wanted to work on computers programming and how I spected my live would be, and yes, THIS is what I wanted (or at least is on the good way :-D). Maybe add some romantics and action-packet and this is the kind of blockbuster I would like to live ;-)

So in few words... in the last four days I would have sleep about no more than 16 or 20 hours :-P

Featuring Norm

Como os dije en mi anterior entrada, debido al estres y desesperación que me estaba ocasionando el que Gaia cascara por cualquier tonteria decidi darme un respiro y mejorar en mi sistema de archivos, y una de esas mejoras fue justamente quitar todas las referencias a SQLite de la capa de abstracción a la base de datos y limpiarla un poquito. ¿Que pasa? Que como tiene la caracteristica de que es bastante generica al tener todas las consultas SQL en archivos externos, entonces ya no hay ninguna referencia al sistema de archivos y se podria aislar como un paquete independiente para poder usarlo en otros proyectos. Pues bien: un poco de magia con la ayuda de GitHub, un poquito de limpieza de codigo para que quede mas presentables y unas cuantas optimizaciones (las cuales incluso han hecho que PirannaFS sea mas limpio y rapido :-) ) y asi es como nacio Norm.

Tradicionalmente, los ORM se han usado para definir a alto nivel los datos, de forma que fuera facil de usar para el programador, pero de esta forma se pierde el control de como se estan guardando (lo cual no es malo, es la mayoria de los casos no es del todo importante), y ademas al hacerlo de una forma generica ralentizando el acceso y termina siendo un cuello de botella y creando problemas en aplicaciones que necesitan un gran rendimiento.

Sin embargo, Norm funciona al reves: en lugar de centrarse en la aplicacion y generar internamente el codigo SQL necesario para acceder a los datos, se centra justamente en estos y en como se accede a ellos en la base de datos y genera el codigo necesario para poder usarlos desde la aplicacion. De esta forma, se puede diseñar a mano codigo SQL optimizado para la aplicacion en concreto teniendo un control total sobre los datos sin tener que escribir todo el glue code necesario para poder usarlo ya que de esto ya se encarga Norm, y ademas genera una API especifica para la aplicacion muy sencilla de usar. Si a esto le añadimos que ademas el codigo SQL no esta embebido dentro del codigo del programa principal como se ha hecho hasta ahora cuando se necesitaba este tipo de optimizaciones sino que se guarda en archivos independientes faciles de mantener y de actualizar sin tocar el codigo del programa principal, no me extraña que al final de la presentacion que hice ayer en las oficinas de Tuenti para Python-Madrid la gente mostrara tanto interes e incluso me diesen ideas para mejorarlo o quisieran colaborar en su desarrollo... :-)

¿Sera posible que por primera vez haya hecho algo que realmente sea util para la gente? ¿Al final sera capaz PirannaFS de sacarme de pobre? :-P
