Ese día, la programadora Grace Hopper se encontraba trabajando con un Mark II en la Universidad de Harvard: el ordenador dejó de funcionar, y los ingenieros encontraron una polilla enganchada a uno de los relés del ordenador. El bicho pasó a la historia de la informática, porque pegaron sus restos en el libro de registro del ordenador, junto a una nota que decía ’First actual case of bug being found’. ...
Like many others, I spend most of my day behind a computer. In order make the most of it (and to keep my body from complaining too much), I try to maintain an optimized setup. For example, I code in Vim, browse with Vimperator, and move windows around in i3. Another common task is filesystem navigation. I prefer to use the command-line for this, but typing cd ~/some/very/deep/often-used/directory over and over again does become cumbersome. ...
For those less familiar with the story and the theories, I thought it might be interesting and useful to have a single thread that lists all of the theories that have arisen given the various questions and unknowns surrounding the Song. There are a lot of brilliant people on these boards and some of them have come up with truly excellent theories, right or wrong, to answer those thoughts we have. ...
Los unos y los ceros llevan milenios entre nosotros, desde algunas culturas primitivas, pero las bombillas se han ido encendiendo poco a poco hasta llegar a su actual omnipresencia en la electrónica. Primero fueron Leibniz y la aritmética, luego Boole y la lógica, y finalmente Shannon y su idea de utilizar el álgebra de Boole para simplificar los circuitos. Una historia apasionante hasta llegar a nuestro smartphone. » David G. Ortiz | blogthinkbig.com
Vivimos en una era de ’ciberguerras’, intrusiones en línea e inseguridad informática, pero también en una época de libertad de acceso a cantidades ingentes de datos e información sin precedentes, de acceso casi ilimitado al conocimiento. No es posible explicar semejante paradoja sin asomarse la historia del ’hacking’ y, aunque parezca mentira, en España esa historia es apasionante. » hackstory.es » Pablo Romero | elmundo.es
We’re happy to announce that fail0verflow, GTVHacker, and Team-Eureka have jointly discovered and exploited a new vulnerability in the Chromecast which allows root access on the current software build (17977) as well as new in box devices » Team-Eureka | xda-developers.com
So, what is systemd? Well, meet your new God. You may have been praying at the alter of simplicity, but your religion is being deprecated. It likely already happened without your knowledge during an upgrade of your Linux box. systemd is the all knowing, all controlling meta-deity that sees all and supervises all. It’s the new One Master Process that aspires to control everything it can - and it’s already doing a lot. It’s what init would look like if it were a transformer on steroids. It’s complicated, multi-faceted, opaque, and supremely powerful. ...
The attack exploits weak randomization, or the lack of randomization, in a key used to authenticate hardware PINs on some implementations of Wi-Fi Protected Setup, allowing anyone to quickly collect enough information to guess the PIN using offline calculations. By calculating the correct PIN, rather than attempting to brute-force guess the numerical password, the new attack circumvents defenses instituted by companies. » Offline bruteforce attack on WiFi Protected Setup » Hands-on: hacking WiFi Protected Setup with Reaver< /a> ...
Last fall, we let you know that Caltech and The Feynman Lectures Website joined forces to create an online edition of The Feynman Lectures on Physics. They started with Volume 1. And now they’ve followed up with Volume 2 and Volume 3, making the collection complete. » The Feynman Lectures on Physics, Volume I » | The Feynman Lectures on Physics, Volume II » The Feynman Lectures on Physics, Volume III » Free textbooks » | Free ebooks ...
Apps that use your smartphone’s microphone need to ask permission, but the motion sensors? No say-so needed. That might not sound like a big deal, but security researchers from Stanford University and defense firm Rafael have discovered a way to turn Android phone gyroscopes into crude microphones. They call their app ”Gyrophone” and here’s how it works: the tiny gyros in your phone that measure orientation do so using vibrating pressure plates. As it turns out, they can also pick up air vibrations from sounds, and many Android devices can do it in the 80 to 250 hertz range – exactly the frequency of a human voice. ...
