A Simple Guide to Cryptography Cryptography is an ancient mathematical science that was originally used for military communications, and designed to conceal the contents of a message should it fall into the hands of the enemy. Recent developments in cryptography have added additional uses, including mechanisms for authenticating users on a network, ensuring the integrity of transmitted information and preventing users from repudiating (i.e. rejecting ownership of) their transmitted messages. In today's world of electronic commerce on the Internet, the need for secure communications is obviously crucial. Cryptographic technologies provide enterprises with the best mechanisms of protecting their information, without putting the business at risk by exposing it on the Net. What is Encryption? The safekeeping of keys, in other words their generation, storage and exchange, is of paramount importance to ensure the security of the data.

[Guide] Installing BURG and Super Boot Manager in Ubuntu (inc 12.04 LTS) Quote: BURG stands for Brand-new Universal loadeR from GRUB. It's based on GRUB, and add features like new object format and configurable menu system. I found a lot of guides showing this but there was only one way to get this thing going for me! Installing BURG and Super Boot Manager edit those two super boot manager sources to look like that. ) which makes the bootloader a little tidier and you can also remove the recovery images from the boot screens as well. Changing the default OS to load I also had a problem getting it to change the default OS to load. Code: sudo gedit /etc/default/burg Look for this line around line 15: and uncommented it by removing the # GRUB_SAVEDEFAULT=true You need to run this into a terminal: grep menuentry /boot/grub/grub.cfg and make note of the Windows line. menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os { Then add or change this line in the burg document we're editing:: to: GRUB_DEFAULT="Windows 7 (loader) (on /dev/sda1)" Sources:

Pictures from a developer's life Yesterday I stumbled upon this collection on a Spanish blog and almost cried with laughter... So I translated it and posted here.

Minecraft Script Pictures Wherein you can see nifty pictures, and read some text too. It's minecraft! Yay! The Code Go to this page if you're interested in the code, so you too can modify your Minecraft save files. Intro So, I realized that there is no combined page for the scripts I've been writing for Minecraft. The Story Beginnings Like many of you, I learned about Minecraft through a link from a blog (I think it was Three Panel Soul). The first script I wrote was a simple interface to edit .mclevel files. Next, I started on a script to convert Dwarf Fortress levels to Minecraft levels. Castles Castles! Over the course of a few weeks, I gradually upgraded the code to allow multiple levels, an offset keep, doors, gatehouses, and towers along the walls. Merging Maps During this whole process, I was becoming familiar with the Minecraft forums and the mapping community. Trees While developing the code for making castles, another thought had been growing in my mind. This is by far my most popular script. City Groundwork

BitLet - the BitTorrent Applet The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky Wednesday, October 08, 2003 Ever wonder about that mysterious Content-Type tag?

A Historical Perspective Unicode OK, so say we have a string: Hello Encodings
