    Grooveshark is a Flash website that lets you play all kinds of music using an interface similar to iTunes. It can be found at http://grooveshark.com/ . Lately I discovered two things. First, I found out there is an Android (phone) Grooveshark application. To be able to use it you have to pay 3$ a month. With this application I can listen to any music anywhere (in Germany) using my cell phone. I don't have to download stuff. I just search and play. It's like having all the music in my phone. I think it's amazing.
    Then today I discovered the Grooveshark desktop application. This application is done with Air, which means it should work on Linux, Windows and OS X. Again, it's like having an iTunes with all the music inside.
    This is the way I want to listen to music. I don't want to own CDs, I don't want to own music files and I don't like shopping. What I like is being able to listen to anything any time. I don't like listening to the same song for the whole day. In that sense, iTunes is expensive for me, because I just like exploring new music, and maybe listening again to a song a few times. I don't want to pay thousands of dollars for all the songs I want to hear. On the opposite end, I can just listen to YouTube, SoundCloud and online radio for free! I think there is a gap in between free on-line radio and iTunes that Grooveshark is filling.
    With Grooveshark I can listen in radio mode, which is like an online radio. But with a difference: for each song played I know the song title, the band name and I see the cover image. I can save the track currently playing in my own library with just one click, so I can easily find it later. No need to download or buy. I can also easily share the song on twitter, Facebook or by e-mail with a simple link like "hey, listen to this amazing track". I can not do that with online radio, FM radio, CDs or iTunes.
    Another thing I can do with Grooveshark is exploring the music libraries of my friends and contacts. I can listen to what they like. I can also create playlists, share playlists and listen to playlists from my friends. I can even embed songs or playlists in websites. I can upload my own tracks to Grooveshark. And no, they didn't pay me to write this post :)
    Since the music and film industries are waging this war suing users while they try to keep their profit margins (in a time where record companies have lost part of it's meaning for existence), I can imagine them taking some action against Grooveshark. Which would be a pity, because this is an amazing way to experience music.

    Last weeks I've been working on releasing a new version of my Flash map. The old one was a world map. I plan to separate the world from the map, so one could have maps of each country or city. It's kind of hard because the source code is very old and unstructured (ActionScript 1!). But it's getting better. I've been also reading an interesting book called "Hackers and Painters". The author talks about Lisp as a great programming language.

    From my experience with Autolisp (for scripting Autocad) 10 years ago I could not experience the greatness of the language. Today I decided to have a look in the Internet and find out what could I do with it in 2010. I found this:

    I had heard about codinghorror.com and I knew it was popular, but somehow I never read it until today. I found it very interesting. I totally agree with the fact that programming alone is difficult. Somehow I managed to finish many projects on my own, but I found that working in a team, even if it's an on-line team, makes things easier. The discussion and sharing of ideas avoids getting stuck on problems. Here another interesting read about the difficulty of predicting development time.

  • Doing SEO for www.13nl.es

    A few years ago I created the new "13 Newsletter" website. It's a newsletter / website about art, which sends a new issue on day 13th each month. There are now almost 600 articles that were written by some friends who collaborate in this project. Surprisingly the site does not have much traffic, so today I tried to improve that by doing some SEO and adding social sharing buttons.

    Each page represented one newsletter edition and included up to 10 articles. A change I did today was to give each of those articles it's own nicely formatted URL. For example: http://www.13nl.es/2010/articulos/558-krautrock-the-rebirth-of-germany.html. I hope search engines will pick up the text in the URL, the page title, and the <H1> and <H2> tags I used. I was already using Google Analytics, so in a few days I should start to see the effect. A second change I did was to include a button next to each article that allows sending it to most social networks and e-mail clients. This way, if someone likes one specific article she can easily send it by e-mail, to Twitter or Facebook. I hope this change has also a positive effect in traffic. 

    Update 2011: After several years writing about art, the team behind 13nl.es decided to move on and the site is now offline.

    Finally I have taken the time to update my 314bits.com website. It had become full of dead links after more than two years I spent working on larger projects. Instead of just fixing some links and adding new projects I decided to install Wordpress, which gives me more flexibility. My current intention is to do a reverse blog. I will add projects going back in time, then add more details to each post as I gather information about them. The old content will be visible at http://www.314bits.com for a few more days until I copy all the data back here.

    Note: This post, and 26 other posts, most related to work and studies, were moved from a Wordpress blog in 314bits.com to this Posterous blog on 10.07.2011, before getting rid of that domain.

  • Su computadora está infectada (con Scareware)

    Hoy un familiar me llamó todo preocupado por que su ordenador se había infectado con muchos virus. Le pedí que me describiera lo que veía en la pantalla y enseguida empezó a parecerme gracioso. Le pedí que tomara una foto de la pantalla para asegurarme. La foto está más arriba. La gracia está en que yo sabía que su sistema operativo era Ubuntu (Linux), pero lo que me describía era una pantalla de Windows, lo cual es totalmente obvio al ver la fotografía. De momento creo que no hay ningún virus para Linux que lo convierta en Windows :)

    Aunque para el que sufrió la "broma" no fue divertido en absoluto. Esto se conoce como Scareware y lo están sufriendo millones de personas. Funciona de la siguiente manera: visitas una página web y de pronto algo que parece una ventana "oficial" te avisa de que tu ordenador está infectado. Además, te ofrecen la solución, generalmente pagando.

    Escribo estas líneas para avisar a los menos expertos. Las páginas web NO pueden saber si tu ordenador está infectado. Si de pronto en tu navegador aparece un mensaje diciendo que estás infectado y que debes descargar la solución inmediatamente, que no cunda el pánico. No hagas clicks.

    Lo que suelo hacer yo cuando encuentro "lo desconocido" en mi ordenador es usar un buscador (en otro ordenador si es posible) introduciendo algunas de las palabras exactas que aparecieron en el aviso. Esto se puede aplicar en muchos casos: un SMS sospechoso, un e-mail que habla de un menor secuestrado y lo mismo con los avisos o mensajes de error en tu pc. A menudo esos mensajes le aparecieron a muchas personas antes que a ti, y quizás puedas encontrar detalles en Internet.

    Los avisos de seguridad en tu ordenador normalmente provienen del sistema operativo (Linux, Mac OS, Windows) o antivirus, y no del navegador (Firefox, Internet Explorer, Opera, Chrome, Safari). Por lo tanto si cierras el navegador y el aviso desaparece significa que el mensaje que intenta asustarte proviene de una página web y puedes olvidarte del tema. Los navegadores a veces sí te avisan de que estás intentando acceder a una web potencialmente insegura. Pero NO te sugieren que para solucionar el problema descargues una aplicación, ni que gastes dinero.

    Pienso que esto es parte de algo llamado Ingeniería social. Una de las maneras de conseguir acceder a sistemas informáticos de otros consiste en encontrar fallos de seguridad en el hardware (la máquina) o el software (el sistema operativo o los programas). Pero existe otra manera. Nosotros los humanos somos el eslabón débil en este caso. Si el sistema informático es seguro, basta con convencer al usuario (usando engaños) de que te facilite el acceso. El aviso que sufrió hoy mi familiar consiste en eso. Engañar al usuario para hacerle creer que le estás salvando de un fallo de seguridad, cuando quizás le estés robando su dinero mientras le pides que por favor instale un virus. La página web por si sola seguramente no es una amenaza de seguridad, pero junto al usuario inexperto sí lo es.

    Lo curioso es que no solo le ocurre al usuario inexperto. Por lo visto los hackers chinos que entraron en 2009 en los sistemas de Google y otras muchas empresas americanas hicieron un análisis exhaustivo de las personas con las que tenían que comunicarse en dichas empresas para encontrar el modo de acceder a sus sistemas (incluyendo nombres, cargos, relaciones, etc).

    ¿Qué se puede hacer al respecto? Supongo que leer y aprender. Estando informado es más difícil que te engañen, y las amenazas parecen menos apocalípticas.

    Encuentro un parecido entre la situación actual y poner a millones de personas al volante sin darles clases de conducir. Lo bueno es que en Internet aprender suele ser gratis :)
