In the same vein, programmers who pay attention to how they construct written language also tend to pay a lot more attention to how they code. You see, at its core, code is prose. Great programmers are more than just code monkeys; according to Stanford programming legend Donald Knuth they are ”essayists who work with traditional aesthetic and literary forms.” The point: programming should be easily understood by real human beings ” not just computers. ...

En un lugar de Melee Island^TM^ de cuyo nombre no quiero acordarme, nuestro wannabe pirata se llamaba Guybrush Threepwood. Tenía unos veinte años, y pesaba poco más de 54 kilos. Aguantaba la respiración durante 10 minutos, intentaba vender unas bonitas chaquetas de piel y soñaba con ser pirata. Todo eran peleas de espadas e insultos, grog y pollos de goma con poleas en medio, hasta que cayó enamorado de la gobernadora Marley que, tras ser secuestrada, le condujo hasta el malvado y temible pirata fantasma LeChuck. ...

Por ahora, la Raspberry Pi viene sin carcasa, por lo que no sólo hay opciones comerciales, sino que la comunidad ha tenido ideas muy creativas: [1], [2] y [3]. Entre todas las opciones, la de imprimir tu propia carcasa me ha llamado la atención. Es sencilla, rápida de hacer y, sobre todo, incluye un plano. Utilizando este plano como base, hemos fabricado una carcasa en madera de contrachapado de 3mm. Las dimensiones del plano encajan en la Raspberry Pi como anillo al dedo. Lo único que hemos tenido que tener en cuenta es el grosor de la madera para las piezas laterales: ...

As a result of a long sequence of coincidences I entered the programming profession officially on the first spring morning of 1952 and as far as I have been able to trace, I was the first Dutchman to do so in my country. In retrospect the most amazing thing was the slowness with which, at least in my part of the world, the programming profession emerged, a slowness which is now hard to believe.

I regularly receive e-mail from people who want advice on how to learn more about computer security, either as a course of study in college or as an IT person considering it as a career choice. First, know that there are many subspecialties in computer security. You can be an expert in keeping systems from being hacked, or in creating unhackable software. You can be an expert in finding security problems in software, or in networks. You can be an expert in viruses, or policies, or cryptography. There are many, many opportunities for many different skill sets. You don’t have to be a coder to be a security expert. ...
