An Overview of Cryptography 1. INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between literally billions of people and is used as a tool for commerce, social interaction, and the exchange of an increasing amount of personal information, security has become a tremendously important issue for every user to deal with. In most common usage, cryptography is most closely associated with the development and creation of the mathematical algorithms used to encrypt and decrypt messages, whereas cryptanalysis is the science of analyzing and breaking encryption schemes. As an aside, the AES selection process managed by NIST was very public. CAST-128/256: CAST-128, described in Request for Comments (RFC) 2144, is a DES-like substitution-permutation crypto algorithm, employing a 128-bit key operating on a 64-bit block. 3.3.
Incredible Concept Bike Folds Down to Size of One Wheel If you’ve ever had to lug a bike with you onto the train or bus, or up a steep flight of stairs, you can probably understand the appeal of lightweight folding bikes. But most of them are too light-weight to handle the demands of serious riders. Dominic Hargreaves was having the same struggles with folding bikes, and after failing to find one that he liked, he decided to make one for himself. The result was The Contortionist, a folding bike that twists around to fold itself entirely into the wheels’ 26-inch circumference. Besides being able to fold down to a previously-unattained size, the bike can go from fully extended to fully folded in just 20 seconds.

Welcome to VX Heavens! (VX heavens) How to build your own USB Keylogger Cause I've searched a lot for a project like this, and I haven't find anything around the Web, I would share my experience of my personal USB Keylogger. It's not really a pure "USB" Keylogger (cause USB HID protocol is much more difficult than PS/2 protocol), but it adapt an USB Keyboard to PS/2 port, while (of course) recording the keys pressed. In this way, even if it's discovered by anybody, it should be confused with a normal PS/2 Adapter. That's the final result: It need just a few component (SOIC PIC and EEPROM can be freely ordered as a sample from ): -PIC 12F1822 (SOIC Version) -EEPROM 24XX1025 (Any 1Mb version will be ok) (SOIC Version) -2 * 4k7 Resistor 1/8 W (Or any resistor of the same value as small as you can solder in the adaptor) -Pickit 2 / 3 (For programming the pic and reading the eeprom) -An USB to PS/2 Adapter that can be opened. And, very important: -A GOOD solder and VERY GOOD soldering abilities. Let's Start. Regards, Jamby
Ubuntu Hacks/Multimedia From WikiContent A modern computer can be a nifty little entertainment center; it has fast video, stereo speakers, probably plenty of disk space for movies and videos. So, how come Ubuntu doesn't know what to do when you insert a DVD or double-click on a video or audio file? The fundamental problem is that there are some critical pieces to the multimedia puzzle that Ubuntu can't distribute in all jurisdictions, so you need to go out and get those pieces yourself. For care and feeding of your multimedia collection, you'll need to eventually work with optical discs. Install Multimedia Plug-ins Music and video files come in a wide variety of exotic formats. On some Linux distributions, getting all of your multimedia files to play seems like it requires all sorts of command-line voodoo. Tweak Your Repository List Many of the multimedia packages you need to install do not reside in the default Ubuntu repository.

How To Configure Remote Access To Your Ubuntu Desktop Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 01/23/2008 This guide explains how you can enable a remote desktop on an Ubuntu desktop so that you can access and control it remotely. This makes sense for example if you have customers that are not very tech-savvy. I do not issue any guarantee that this will work for you! 1 Preliminary Note I have tested this on an Ubuntu 7.10 (Gutsy Gibbon) desktop. 2 Enabling The Remote Desktop We don't have to install anything to enable the remote desktop on Ubuntu. (JavaScript must be enabled in your browser to view the large image as an image overlay.) In the Remote Desktop Preferences window, you can configure the remote desktop connection. vncviewer falko-desktop:0 Then there are the security settings. But what you should do is set a password for your remote desktop (without a password anyone who happens to find out your system's address - e.g. by scanning the network - can access your desktop): Instead of we can now use
Tutto Giappone si ferma a tre mesi dallo tsunami - Mondo di Antonio Fatiguso L'allarme fissione e' l'ultimo spettro generato dalla disastrata centrale di Fukushima. L'annuncio del gestore Tepco sulla presenza nel reattore n.2 di tracce di xenon, gas solitamente sprigionato dalla reazione dell'uranio, ha proiettato in mattinata scenari inquietanti via via migliorati con l'analisi e la lettura dei dati raccolti, fino a quando il ministro per l'Emergenza nucleare Goshi Hosono ha gettato in serata acqua sul fuoco. Hosono si e' detto ''ottimista'' su arresto a freddo e messa in sicurezza dei reattori ''entro fine anno'': le attivita' di ''raffreddamento procedono stabilmente e non c'e' motivo di cambiare i piani'', ha spiegato, anche con i segnali di fissione. I riflettori si sono riaccesi su Fukushima quando la Tepco ha, ''a scopo precauzionale'', cominciato a iniettare acido borico per neutralizzare possibili reazioni, mentre l'Agenzia per la sicurezza atomica (Nisa) ha avviato i suoi riscontri.
