Avui és el dia de l'estrena de Serenity... que segons un amic, en Pedro Jorge, és la millor pel·lícula de ciència ficció de l'any. I això té molt mèrit, doncs com tothom que el coneix sap, és una persona prou entesa i molt exigent.
Jo no hi aniré a veure-la fins dissabte... així que, si us plau, no m'expliqueu res del seu argument!
De moment, i fins dissabte... el trailer.

 Publicada una nova versió de Metasploit Framework
This is the Metasploit Project. The goal is to provide useful information to people who perform penetration testing, IDS signature development, and exploit research. This site was created to fill the gaps in the information publicly available on various exploitation techniques and to create a useful resource for exploit developers. The tools and information on this site are provided for legal penetration testing and research purposes only.
Aquesta és una versió de manteniment, que incorpora les diverses actualitzacions des de la versió anterior, afegint alguns exploits addicionals i altres millores menors.

Tor és una xarxa descentralitzada d'ordinadors que ajuden a millorar la privadesa de les persones mentre naveguen per la web, la missatgeria instantània i d'altres aplicacions que fan servir Internet. Actualment hi ha uns 250 servidors arreu del món que actuen com a proxys anònims
Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy.
The solution: a distributed, anonymous network Tor helps to reduce the risks of both simple and sophisticated traffic analysis by distributing your transactions over several places on the Internet, so no single point can link you to your destination. The idea is similar to using a twisty, hard-to-follow route in order to throw off somebody who is tailing you—and then periodically erasing your footprints. Instead of taking a direct route from source to destination, data packets on the Tor network take a random pathway through several servers that cover your tracks so no observer at any single point can tell where the data came from or where it's going.
To create a private network pathway with Tor, the user's software or client incrementally builds a circuit of encrypted connections through servers on the network. The circuit is extended one hop at a time, and each server along the way knows only which server gave it data and which server it is giving data to. No individual server ever knows the complete path that a data packet has taken. The client negotiates a separate set of encryption keys for each hop along the circuit to ensure that each hop can't trace these connections as they pass through.
Once a circuit has been established, many kinds of data can be exchanged and several different sorts of software applications can be deployed over the Tor network. Because each server sees no more than one hop in the circuit, neither an eavesdropper nor a compromised server can use traffic analysis to link the connection's source and destination. Tor only works for TCP streams and can be used by any application with SOCKS support.
For efficiency, the Tor software uses the same circuit for connections that happen within the same minute or so. Later requests are given a new circuit, to keep people from linking your earlier actions to the new ones.
