Multitasking and Task Switching
viernes, junio 20, 2008
En Agosto del 2001, un equipo lidereado por el Profesor David Meyer publico su estudio sobre "multitasking" (en el "Journal of Experimental Psychology"). De acuerdo con Meyer: "multitarea crea problemas de salud y no es eficiente"
En nuestra sociedad actual, las personas frecuentemente realizan varias tareas a la vez. Esto comúnmente requiere distribuir nuestros limitados recursos para ordenar y completar cada una de las tareas exitosamente. Esta distribución/balanceo no es sencillo, en muchos casos conlleva a aumentar la ineficiencia en realizar cada una de las tareas individuales. Por ejemplo, utilizar el celular mientras se maneja conlleva a dos cosas: tener una comunicación pobre y manejar mal. En el cerebro, administrar múltiples tareas ("Multitasking") es realizada por un proceso mental principal que administra cada tarea individualmente y determina como, cuando y con que prioridades se realiza. “Multi-taskers” are really just splitting their time and attention into smaller slices than you; no one can really do more than one thing at a time.

The table of equivalents / replacements / analogs of Windows, Linux and Mac OS X.
miércoles, junio 18, 2008
Hello everybody. Because I didn't find on Internet a list of analog sotware between windows/linux and Mac OS X. I decided to make a list of replacement software for people (like me) who've just migrated to this new stable, great, and almost-perfect operating system. You can review the list here: http://www.plucas.com.mx/mac/It is based in the original http://www.linuxrsp.ru/win-lin-soft/, but the original is for windows->linux analog, here is more focues in linux/windows -> Mac OS X. The list is still on development, if you have a comment please email me at master@plucas.com.mx. Thank you. Etiquetas: linux, mac, windows
Cafe Tacvba Cancún 14.06.08
miércoles, mayo 28, 2008
 El sábado 14 de Junio del 2008 se presentará Cafe Tacvba en el Estadio Andrés Quintana Roo en la paradisiaca Ciudad de Cancún.
Los precios van desde 100 en general hasta 500 pesos en el área VIP los boletos están a la venta en arenapremier.com, ya veremos como se pone, ya que los últimos eventos que he asistido en Cancún organizados por diferentes organismos han dejado mucho que desear y están muy fuera del estándar al que estoy acostumbrado en el DF.
Aqui les dejo el poster que tome sobre Yaxchilan, así que señoras y señores haya nos vemos un evento así no se puede dejar pasar nunca en la vida.
El último concierto que fui de ellos fue con Liwiz cuando no era tan geek y todavía se acordaba de su viejo amigo en DGSCA.

２０１２年はけいじの年です。
sábado, abril 12, 2008
２０１２年はけいじの年です。いろいろなよげんがあります。ながいマヤのバクトウンしゅうきはおわります。いつかそのうちせかいのじばはかえります。マヤのよげんによるとこのせかいはこんにち私たちがしっているせかいからかわるそうです、そうしてノストラダムスのよげんがいっちするけんきゅうによるとすいせいがとてもちかくをとおるそうです。だからしぜんさいがいをひきおこします。にも二つよげんはたいようしゅうき。 私にしつもんします。私のマイルはmasterplucas@gmail.comです。かんぱい！
Nuevo número en México es 84216530, llama ahora!
新しメキスコの電話のばんごがあります！ メキスコの友だち、電話のばんごは84216530です。メキスコのばんごです。
Hola! Contrate el servicio de SkypeIn, mi teléfono en la Ciudad de México es 8421 6530, por si gustan llamarme, es un número local en México, a mi me llega la llamada a mi computadora por el servicio de Skype, casi siempre estoy conectado a Internet en mi trabajo y la mayor parte en mi casa así que pensé que era una buena idea contratarlo, mi mamá fue la primera que me llamo y le gusto bastante la idea, la llamada fue excelente incluso aunque la recibí con el Internet de mi casa en Andalucía que es un poco lenta.
Si me quieren llamar para cotorrear un rato puede ser el fin de semana (si no estoy en la playa) o entre semana después de las 7 u 8pm (saliendo de trabajo 10 mins después para alcanzar llegar a mi casa). En caso de que todo fallé, pueden dejar un mensaje en el buzón y yo les regreso la llamada. Para el resto del mundo igual me pueden llamar a mi skype, mi nombre de usuario es masterplucas, necesitan una computadora, bocinas y micrófono, que aunque parezca increíble (para mi) todavía hay personas que no tienen una simple diadema de $5dll para hacer una llamada gratuita en Internet.
Cheers!
Hybrid Operating Systems

Hybrid Operating Systems Virtual Machines
 Maybe you have listened about virtual machines (VM), if you are a windows guy, it’s common now to use VirtualPC to run another version of Windows, or even if you are Linux guy you could run Windows using VirtualBox.
Now with every new generation of computers (processors with two or more cores) it’s common for a power user to virtualize an operating system (OS). Virtualization software it’s getting more and more complex and the integration gets better with each release, for both sides: the commercial OSs and even for the open source community.
But, What is a Hybrid Operating Systems (HOS)? An HOS is a computer running the base operating system, and one or more OSs at the same time using a virtual machine.
To buy a capable computer for a power user it’s not a choice it’s just mandatory to get a decent machine with tons of memory (the top for 32bits computer is 4GB of memory), and a huge hard disk. For a developer it’s even more convenient; the more memory you get the more OSs running at the same time you will be running.
Mac OS X: A solid *NIX platform with the best user experience natively!
If you use Windows, you can install another Windows OSs (instead of use dual boot), and even a Linux distribution (I like Debian or Debian-based distributions), if you use Linux well, you can do the same, but if you use a Mac you can get the best of the worlds “natively” in the same computer, a solid BSD system with a gorgeous user interface, with all the application you don’t have on a “new” Windows-PC , if you need Windows you can install using Boot Camp and have the best of this operating system, you can use this partition for a double booting and you have all the advantages of a native powerful PC (specially for games) and when you are working with your Mac OS X you can start a virtual machine to use all the application you need from the Windows world, isn’t it beautiful?.
In several web pages mention the possibility to start Leopard (Mac OS X latest version) on VM on any OS, but I can guarantee that some drivers are missing and just will not work the way it’s designed, without mentioning the legal issue.
Best base OS for Multi-Platform Programmers.
Now talking about developers, for a good developer you don’t have boundaries in developing, you can program a PIC microcontroller with 8bits word, two levels of stack and one accumulator or even program a very high level scripting language. As a developer I do not recommend to engage for the eternity (not even for a while) with a specific language.
The best scenery for a professional developer using several platforms is to get a Mac OS X and use Linux and/or Windows on VM, there are two native options in the Mac OS X world: parallels and vmware. I've been using Mac for the latest months and I was able to test both programs, I can conclude: Parallels is the best. The advantage for vmware is to use both cores of the processor, but that’s a disadvantage, you must not let Windows use the two cores, because when it freezes makes your Mac so slowly, and vmware it’s not well integrated as parallels is, even with the last version using the coherence-like mode cloned from Parallels.
There is one annoying feature on vmware that I hate when I'm running Linux, you must click into the window to grab keyboard focus, instead of just click on the title window to set the focus, so if you need to move your mouse and keyboard focus on another window you must press a key combination to “get out” of the window, the other bad news is the keyboard re-map that Parallels integrates. On Windows world you use Ctrl+C to Copy on Mac and you use [Apple]+V to Paste, if you are switching from Explorer to Finder applications you easily get confused what key-combination to use, and it’s frustrating, with Parallels I keep using [Apple]+anything, an additional note is that if you press left-[Apple] key you get the Window start menu, if you press right-[Apple] key you get the menu option key, I like that.
Finally, if you get a Mac you get the best user experience and a solid platform, you can use Windows fully integrated with Mac with excellent performance and without rebooting, also you can install Linux, to get the 3 most popular OSs on the market running parallels on your system.
Talking technically. You can run Xcode natively to program iPhone applets, or use it to program Mac OS Applications using Objective C, you can also run applications like Apache Web Server, MySQL, PostgreSQL and use any language using MacPorts or fink to compile or use a certain applications for example Java, C/C++, PHP or Ruby, you can install Boot Camp to run Windows natively on Mac and use a high-demanding application like games, you can stay on Mac and run your Boot Camp partition to use Visual Studio .NET and SQL Server and program C#, Visual Basic.NET, TSQL. If this is not enough for you, you can install Linux and run all the Open Source applications without porting (and waiting someone do the dirty job), and the best part, you can use your favorite distribution (I like Ubuntu server, it has a LAMP solutions already on the installation, and without GUI), you must make your development environment as close as the production environment, and this is just perfect for the deploy phase on the developing cycle.
If you’re thinking to buy a new computer, think twice, Mac is getting a real option for professional developers.
