The size of the card was 7 3⁄8 in × 3 1⁄4 in (187.325 mm × 82.55 mm). This example displays the 1964 EBCDIC character set, which added more special characters to earlier encodings. A punched card, punch card, IBM card, or Hollerith card is a piece of stiff paper that contained either commands for controlling automated machinery or data for data processing applications. Gernreich alphabet Gernreich is an alternative alphabet for English invented by Michael Carnright when he was 14. The letters are like building blocks which are connected together to make words, which in turn can be connected together to make sentences. Micheael usually uses graph paper to write this alphabet.

Answer: There are a lot of everyday materials that fluoresce, or glow, when placed under a black light. A black light gives off highly energetic ultraviolet light.
Baudot Paper Tape Code This table presents a programmer's quick reference to the "Baudot" character set. IMPORTANT NOTE: The code presented here is with reference to usage in the computer industry. The original, true, baudot code differs from that presented below. The following table presents CCITT Alphabet No 2 which was developed from Murray's code which was in turn developed from Baudot's code. Baudot's code was replaced by Murray's code in 1901. And ITA2 replaced both by the early 1930's, so virtually all "teletype" equipment made in the U.S. uses ITA2 or the U.S. national version of the code.
Top 15 Open Source/Free Security/Hacking Tools 1. Nmap Nmap (“Network Mapper”) is a free and open source (license) utility for network discovery and security auditing. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

XHTML Character Entity Reference This page contains the 252 allowed entities in HTML 4 and XHTML 1.0, as outlined in section 24 of the official HTML 4 specifications, published by the W3C. If you find it helpful we'd really appreciate a social share! Each entity is contained within a small box that contains four lines: The first line shows how the entity will be displayed on your webpage. The second line contains the entity reference, in the form &entity_name; (i.e. an ampersand, the entity name, and then a semi-colon). This is the code that you should place in your webpage.

The Other Mystery of Easter Island Moai statues Easter Island is branded into popular consciousness as the home of the mysterious and towering moai statues, but these are not the only curiosity the South Pacific island holds. Where the moai are fascinating for their unknown purpose and mysterious craftsmen, the island's lost language of Rongorongo is equally perplexing. The unique written language seems to have appeared suddenly in the 1700s, but within just two centuries it was exiled to obscurity. Known as Rapa Nui to the island's inhabitants, Rongorongo is a writing system comprised of pictographs. It has been found carved into many oblong wooden tablets and other artifacts from the island's history.
Download Enigma Simulator This software is an exact simulation of the 3-rotor Wehrmacht (Heer and Luftwaffe) Enigma, the 3-rotor Kriegsmarine M3, also called Funkschlussel M, and the famous 4-rotor Kriegmarine M4 Enigma cipher machine, used during World War II from 1939 until 1945. The sim has a very authentic feeling with its hands-on approach: you can select between the three models, actually lift out and insert different rotors, adjust their ring setting and set up the plugboard. The internal wiring of all rotors is identical to those that were used by the Wehrmacht and Kriegsmarine. This simulator is therefore fully compatible with the various real Enigma models and you can decrypt authentic wartime messages or encrypt and decrypt your own messages.

Comparison of web application frameworks From Wikipedia, the free encyclopedia This is a comparison of notable web application frameworks. General[edit] Basic information about each framework. Writing programs using ordinary language In a pair of recent papers, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory have demonstrated that, for a few specific tasks, it’s possible to write computer programs using ordinary language rather than special-purpose programming languages. The work may be of some help to programmers, and it could let nonprogrammers manipulate common types of files — like word-processing documents and spreadsheets — in ways that previously required familiarity with programming languages. But the researchers’ methods could also prove applicable to other programming tasks, expanding the range of contexts in which programmers can specify functions using ordinary language. “I don’t think that we will be able to do this for everything in programming, but there are areas where there are a lot of examples of how humans have done translation,” says Regina Barzilay, an associate professor of computer science and electrical engineering and a co-author on both papers.
