The Toolbox: a directory of useful single-page sites and apps. 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. Symmetric Cryptography – Secret Keys Asymmetric Cryptography – Public/Private Keys.
[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! I could install but never actually have it work properly afterwards. 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.

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!

In the summer of 2007, shortly after launching Novlet, Daniele and I still had time to spare and were looking for something new to build.
Sure enough, within a short period, Daniele came up with the idea that would soon become BitLet: a BitTorrent client that could run in a browser without requiring users to install anything on their computer. Back then, browsers had very limited capabilities: AJAX had been recently introduced (in 2005), web applications were moving from static pages to dynamic client UIs but no browser could do things like opening sockets and writing files locally, central requirements for a peer to peer file sharing application.
We found a solution in an unlikely piece of technology: Java applets. Despite Java’s success as a programming language, applets had never been that popular among casual users. One of the main reasons is that Java applets didn’t look that great. The interface we had in mind was very simple, centered around a streamlined download window.

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? You know, the one you're supposed to put in HTML and you never quite know what it should be? Did you ever get an email from your friends in Bulgaria with the subject line "???? ?????? I've been dismayed to discover just how many software developers aren't really completely up to speed on the mysterious world of character sets, encodings, Unicode, all that stuff. But it won't. So I have an announcement to make: if you are a programmer working in 2003 and you don't know the basics of characters, character sets, encodings, and Unicode, and I catch you, I'm going to punish you by making you peel onions for 6 months in a submarine.
And one more thing: In this article I'll fill you in on exactly what every working programmer should know. A Historical Perspective The easiest way to understand this stuff is to go chronologically. And all was good, assuming you were an English speaker. Unicode Hello Encodings. 10 Technical Papers Every Programmer Should Read (At Least Twice) 10 Technical Papers Every Programmer Should Read (At Least Twice) this is the second entry in a series on programmer enrichment Inspired by a fabulous post by Michael Feathers along a similar vein, I’ve composed this post as a sequel to the original.
That is, while I agree almost wholly with Mr. Feather’s1 choices, I tend to think that his choices are design-oriented2 and/or philosophical. All papers are freely available online (i.e. not pay-walled)They are technical (at times highly so)They cover a wide-range of topicsThe form the basis of knowledge that every great programmer should know, and may already Because of these constraints I will have missed some great papers, but for the most part I think this list is solid.

Vi tips and tricks: Ten cool commands sure to impress your friends. When coming to grips with the vi editor—either for the first time or as a regular user—most people tend to have a grasp of the core command set that allows them to perform those functions they use most regularly: navigating or saving a file; inserting, updating, deleting, or searching for data; or quitting without saving changes. However, the vi editor is extremely powerful and rich in features and functionality. Even after many years of use, you can still uncover new commands that you didn't realize existed.
The commands covered in this article are amongst those less well known, but they can help you to work smarter by short-cutting existing methods you may use or allowing you to do something that you never realized you could do with vi. Before we start just a recap on the two modes of vi: command and insert. Command mode allows the user to execute commands to modify text, navigate around the file or control your vi session in some way. Turn line numbering on and off Listing 1. . #!
#! #! 4!! Crack/Keygen Sites That Are Safe To Use. Blindly searching the web for cracks & keygens is about as smart as using Limewire to search for antivirus software - something not well-advised. Undoubtedly and unfortunately, the number of crack sites with overtones of a malicious agenda heavily outweigh sites that just want to serve up the honest goods. Having said that, there actually are quite a few creditable ‘crack’ sites that won’t try to bombard you with full-screen popup ads, or commandeer your computer into a spam-loving Kraken or Srizbi Botnet army.
We’ve done the hard work for you, and present a list of “clean” crack sites for all the latest warez. Be aware that the site reviews herein only include information about each site, not the contents of the ‘cracks’ themselves. Always use a reputable antivirus and antispyware program on cracks & keygens before using them. Recommended (Clean) Crack Sites While these websites are deemed adware/malware free, always be sceptical of their “affiliate links” to other crack sites. Sound Types.

Google's Android Reborn as Network-Hacking Kit.
The Pwn Pad Photo: Pwnie Express The folks at security tools company Pwnie Express have built a tablet that can bash the heck out of corporate networks. Called the Pwn Pad, it’s a full-fledged hacking toolkit built atop Google’s Android operating system. Pwnie Express will be selling the cool-looking hack machines — based on Google’s Nexus 7 tablets — for $795. They’ll be introduced at the RSA security conference in San Francisco next week, but Pwnie Express is also releasing the Pwn Pad source code, meaning that hackers can download the software and get it up and running on other types of Android phones and tablets. Some important hacking tools have already been ported to Android, but Pwnie Express says that they’ve added some new ones.
Most importantly, this is the first time that they’ve been able to get popular wireless hacking tools like Aircrack-ng and Kismet to work on an Android device. A year ago, we introduced you to the Pwn Plug, another Pwnie Express product. Apple said “no.” YouTube Playlists for Learning Programming. YouTube has been very good platform for learning any thing.

Category:Programming Tasks.
Programming tasks are problems that may be solved through programming. When such a task is defined, Rosetta Code users are encouraged to solve them using as many different languages as they know. The end goal is to demonstrate how the same task is accomplished in different languages. These are the Programming Tasks that have been defined and solved. Feel free to add solutions in languages not already included. The Category:Simple is a small subset with only "really simple" tasks, like "Hello World", and demonstrations of basic language-features.
The Category:Draft Programming Tasks is a list of tasks, some of which are just awaiting more implementations before they can be promoted to tasks. Others may well have problems, (check their discussion and history pages). Read the guidelines on creating new tasks. The following 871 pages are in this category, out of 871 total.
