Interaction Design Foundation. Privacy for anyone anywhere. Tails is a live operating system that you can start on almost any computer from a DVD, USB stick, or SD card.

Privacy for anyone anywhere

It aims at preserving your privacy and anonymity, and helps you to: use the Internet anonymously and circumvent censorship; all connections to the Internet are forced to go through the Tor network; leave no trace on the computer you are using unless you ask it explicitly; use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging.

Nine-board Tic Tac Toe

Players take turns making marks (human 'X', computer 'O') in the ordinary tic-tac-toe boards. The first mark can appear anywhere. Each subsequent mark gets made in any un-marked spot in the ordinary board that corresponds to the spot where the previous mark got made. 10-year-old problem in theoretical computer science falls.

10-year-old problem in theoretical computer science falls

Scott Brauer Interactive proofs, which MIT researchers helped pioneer, have emerged as one of the major research topics in theoretical computer science. In the classic interactive proof, a questioner with limited computational power tries to extract reliable information from a computationally powerful but unreliable respondent. Interactive proofs are the basis of cryptographic systems now in wide use, but for computer scientists, they’re just as important for the insight they provide into the complexity of computational problems. Twenty years ago, researchers showed that if the questioner in an interactive proof is able to query multiple omniscient respondents — which are unable to communicate with each other — it can extract information much more efficiently than it could from a single respondent.

Piet (programming language) History[edit] Early implementations of INTERCAL were tied to the IBM System/360 and an unidentified Atari computer (probably the Atari 2600) and have not survived.

Piet (programming language)

For many years INTERCAL was represented only by paper copies of the INTERCAL manual. The language's revival in 1990 as an implementation in C under Unix stimulated a wave of interest in the intentional design of esoteric computer languages. Turing tarpit. A Turing tarpit is a language that aims for Turing-completeness in an arbitrarily small number of linguistic elements - ideally, as few as possible.

Turing tarpit

History[edit] The 1950's and 1960's were something of a heyday for Turing tarpits. Academic interest in them was keen, and they enjoyed considerable popularity in computability research circles. Near the middle of the 1960's, however, the bubble of optimism surrounding them burst. In his 1987 paper The Busy Beaver Game and the Meaning of Life, Allen Brady relates a private conversation with John McCarthy (inventor of LISP) circa 1964 in which Prof. We thought if we were to find the smallest universal machine then we could learn a great deal about computability -- of course that wouldn't be so!

Top 10 Truly Bizarre Programming Languages

These types of languages are usually called “Esoteric Programming Languages”. An esoteric programming language (sometimes shortened to esolang) is a computer programming language designed either as a test of the boundaries of programming language design, to experiment with weird ideas or simply as a joke, rather than for practical reasons. There is usually no intention of the language being adopted for real-world programming. Such languages are often popular among hackers and hobbyists. Usability is rarely a high priority for such languages; often quite the opposite. KI Bioinformatics and Computing Core Facility - Rous. The Little Lisper - Daniel P.

Prompt Magic

[edit] Introduction As Linux/UNIX people, we spend a lot of time working in the shell, and in many cases, this is what we have staring back at us: bash-2.04$ If you happen to be root, you're entitled to the "prestige" version of this beautiful prompt: bash-2.04# These prompts are not exactly pretty.

The Bourne Again Shell (bash) 8.3.1 Environment Variables A Linux system is a complex beast, and there's a lot to keep track of, a lot of little details that come into play in your normal interactions with various programs (some of which you might not even need to be aware of).

The Bourne Again Shell (bash)

Nobody wants to pass a bunch of options to every program that gets run, telling it what kind of terminal is being used, the hostname of the computer, how their prompt should look... So as a coping mechanism, users have what's called an environment. The environment defines the conditions in which programs run, and some of this definition is variable; the user can alter and play with it, as is only right in a Linux system. Pretty much any shell will have environment variables (if not, it's probably not a very useable shell). Set by itself will show you all of the environment variables that are currently defined, as well as their values. Collusion/website/demo.html at master · toolness/collusion.

cURL - How To Use. Curl - transfer a URL curl [options] [URL...] curl is a tool to transfer data from or to a server, using one of the supported protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP).

cURL - How To Use

The command is designed to work without user interaction. curl offers a busload of useful tricks like proxy support, user authentication, FTP upload, HTTP post, SSL connections, cookies, file transfer resume, Metalink, and more. As you will see below, the number of features will make your head spin! Curl is powered by libcurl for all transfer-related features. The URL syntax is protocol-dependent. You can specify multiple URLs or parts of URLs by writing part sets within braces as in:
