Supongo que todos estáis al tanto de la hazaña de Felix Baumgartner, el hombre que ha saltado desde una altura de más de 120000 pies desde un globo, convirtiéndose en el hombre que más alto ha saltado y el que ha alcanzado la mayor velocidad sin ayuda mecánica como parte de la misión Red Bull Stratos. En Pybonacci somos tan frikis, que vamos a visualizar el salto supersónico de Baumgartner como mejor se nos da: con Python ;) ...
CSS was meant to style academic documents and simple sites (eg. wiki, blogs) where the cascade and descendant selectors makes a lot of sense. Unfortunately many sites we build nowadays are way more complex than that, and what used to work on simple projects doesn’t scale very well. We need to find smarter ways to code CSS to avoid the common issues and re-think the way we do our work. We should learn from the experience of other devs working in different domains, and apply into our own domain. Things like separation of concerns, modularity, encapsulation, DRY can (and should) be applied to large scale CSS projects as well. The main problem is that most people who are good at CSS doesn’t necessarily have a Computer Science background, most of them started as designers and learned CSS by themselves (that was my case¦). That’s the main reason why I’m writing this post. ...
Apple tomó muchas decisiones técnicas con el objetivo de mejorar la ”experiencia de usuario”, pero por sí mismas serían inútiles -o más perjudiciales- si no van acompañadas de medidas de control estrictas. Es fundamental el papel de los controles de las aplicaciones en el App Store (¡ojo! no los justifico). Independientemente de otras consideraciones políticas, dado su simplicidad y soluciones ad hoc, el iOS sería muy fácil de ”abusar” por los desarrolladores y aplicaciones. ...
Working with redirections in bash is really easy once you realize that it’s all about manipulating file descriptors. When bash starts it opens the three standard file descriptors: stdin (file descriptor 0), stdout (file descriptor 1), and stderr (file descriptor 2). You can open more file descriptors (such as 3, 4, 5, …), and you can close them. You can also copy file descriptors. And you can write to them and read from them. ...
Have you ever tried to add a footnote to a table inside the tabular environment? Even though the index is printed, the search for the actual footnote will be in vain. » Tom | texblog.org
This course details the exploitation of SQL injection in a PHP based website and how an attacker can use it to gain access to the administration pages. Then, using this access, the attacker will be able to gain code execution on the server. The attack is divided into 3 steps: Fingerprinting: to gather information on the web application and technologies in use. Detection and exploitation of SQL injection: in this part, you will learn how SQL injections work and how to exploit them in order to retrieve information. Access to the administration pages and code execution: the last step in which you will access the operating system and run commands. » pentesterlab.com
NAND flash memory-based storage devices, such as SSD, eMMC, and SD cards, have been widely being used for ranging from mobile to server systems. Since they are known to have different characteristics from the conventional rotational disks, a file system, an upper layer to the storage device, should adapt to the changes from the sketch. F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead. ...
El tiempo… ese bien tan preciado para muchos, tan desperdiciado por la mayoría… Eso que los relojes nos ayudan a medir o controlar a diario. Hablemos de relojes. Los hay de muchísimos tipos: de muñeca, de pared, analógicos, digitales, con números arábigos, con números romanos, o hasta sin números. Y, evidentemente, los hay con motivos friki-matemáticos. Y de esos son los que vamos a ver a continuación, de relojes matemáticos. ...
This project is based on the entire ABC’s LOST TV show scripts, 115 episodes in 7 seasons, that I managed to parse from Lostpedia. I also parsed this page with additional information about hidden characters relations. My aim for this project is not (only) to visualize some properties and patterns out of the script but actually to allow to read and enjoy the series in a different way. I plan to add new views (will inform through twitter), more aimed to reveal global patterns in the script, and I will include cliffhangers and writing teams information. ...
You are looking at the HoneyMap, a real-time world map which visualizes attacks captured by honeypots of the Honeynet Project. Red markers on the map represent attackers, yellow markers are targets (honeypot sensors). » Florian Weingarte and Mark Schloesser | HoneyMap / honeynet.org
