Receta 100% Italiana: Pasta al pomodoro / Pasta al tomate

Voy a poner una receta italiana de mi italiana favorita... bueno, de mi persona favorita en general, mi novia. Es una receta sencilla pero que en España (y muchos otros países, imagino) nunca la encontrareis bien hecha (la pasta estará blanda y deshecha, el tomate ácido o frito, la salsa mal mezclada, etc, etc).

Imagino que en Italia habrá tantas recetas de pasta al pomodoro como mammas, pero esta es una muy buena y sencilla.

Configuración absurdamente rápida del firewall Shorewall

Shorewall es un software que permite crear más o menos fácilmente un firewall a partir del firewall interno de Linux (IPTables). Shorewall viene con casi todas las distribuciones de Linux, así­ que si no lo tienes instalado busca el paquete que por ahí andará. Este artículo detalla solamente (y de forma muy básica) la configuración de Shorewall para un ordenador conectado a Internet a través de una pasarela (sea esta un router DSL u otro ordenador) y que está integrado en una red sencilla. No se detallará la instalación, así que, insisto, si puedes instala el paquete de tu distribución.

Lo primero que debo decir es que no soy un experto, ni mucho menos, de shorewall; de hecho aprendí a medio usarlo ayer y este artículo es más que nada una referencia futura. Pero esta configuración a mi me funciona y me imagino que podrá ser útil a más gente.

The End Is Near: I switched from Mandriva to Ubuntu

  • 1995: I installed a Red Hat distribution. It was crap mostly because of the RPM-hell, but better than MS-DOS or Windows 95, so I kept it.
  • 1996: I installed Debian. No RPM-hell but nice apt-get. Loved it.
  • 2004: My blood boiled after and entire afternoon trying to make a scanner work, which I knew was supported by SANE. Deleted the Debian and installed Mandriva. The scanner, and almost everything else, worked at once.
  • 2009: After five years using and advocating Mandriva and making fun of the average Ubuntu user I switched to KUbuntu 9.04. Talk about consistency.
So, why?. Well, it's not like Ubuntu has been better all the time that Mandriva and I just keept resisting for brand loyalty; I've been testing almost every major Ubuntu release, and still found the current (at the time) Mandriva version superior. Superior for me means that more hardware was detected and configured to work, the KDE desktop was better configured and integrated (I don't use the lobotomized Gnome), and the Mandriva administration tools were superior.

But two weeks ago I tested KUbuntu 9.04 and found it superior. The hell froze. It was superior because:

o All the things that Mandriva never got really right on my Sony Vaio just worked on Ubuntu. This include:

  • The suspend to disk and RAM (in Mandriva about 30% of the time the computer would never came back from suspend to RAM, and suspend to disk never worked.)
  • The sound; Mandriva pulseaudio configuration would sometimes leave me without sound, usually when opening a flash video from Firefox or coming back from suspend to RAM. I fixed that killing pulseaudio and restarting the sound system, but it was a pain.
  • The Firefox addons. Ubuntu uses an special Firefox extensions that install Flash, Java, and other things automatically the first time you need it. It shows a wizard and installs everything, like in Windows. With Mandriva you need to go chasing the plugins on the net and install them yourself, or fiddle with repositories. Ubuntu has some other user-friendly niceties like these, like the NVidia/ATI driver installer and configurator (envy-ng.)
o The speed. Holy cow, this thing is fast! It's not only much faster than Mandriva (much faster booting, faster desktop, much better user experience all around) is also much faster than previous Ubuntu versions.

There is only one thing I'll miss from Mandriva, and it's its awesome DrakConf. KUbuntu has a loosy collection of configuration programs under "System", some other things you're supossed to configure with KDE "SystemSettings" and some other things you are supossed to configure clicking on some taskbar icons, but Mandriva DrakConf got most of these under a single, user friendly GUI and it also got a lot more configuration modules than Ubuntu have.

So, Ubuntu users, you can mock me now. I'll not reply, as a penitence.

How to easily* compile KDE4 from sources (* if you're a guru like me)

I found that on my system, using a compiled KDE 4 from the sources goes much better than Mandriva's provided packages. And since it's pretty easy to do, I'm writing an article detailing the steps. Back in 2004 I wrote an article about running a KDE 3 version compiled from CVS (in spanish that time). Since your distribution probably already have packages for KDE4 you could be wondering what are the advantages of compiling KDE4 over using the distro packages. These are:

  • You can optimize the compilation for your target machine. This means that if you, for example, have a Dual Core 2 CPU you can instruct the GCC compiler to generate code specific to the features of your processor (like SSE and a lot of other things) that will make the binary run noticeably faster on your computer than the generic code compiled for Pentium.
  • You'll always be on the cutting edge, having the very last KDE version. Of course this is both good and bad; it means you'll have always the latest features but you'll have too the latest bugs. My advice is to only install form sources when the current KDE version (4.1.0, 4.2.0, etc) is at least at beta stage.
  • If you're a programmer and find a bug or want to implement some feature, you'll have the source code to it.
  • You'll not depend on the options choosen by your distribution package maintainer.
