Markus Kuhn (computer Scientist)
Markus Guenther Kuhn (born 1971) is a German computer scientist, currently working at the Computer Laboratory, University of Cambridge and a fellow of Wolfson College, Cambridge. Education Kuhn was educated at University of Erlangen (Germany), he received his Master of Science degree at Purdue University and PhD at the University of Cambridge. Research Kuhn's main research interests include computer security, in particular the hardware and signal-processing aspects of it, and distributed systems. He is known, among other things, for his work on security microcontrollers, compromising emanations, and distance-bounding protocols. He developed the Stirmark test for digital watermarking schemes, the OTPW one-time password system, and headed the project that extended the X11 misc-fixed fonts to Unicode. In 1994, as an undergraduate student, he became known for developing several ways to circumvent the VideoCrypt encryption system, most notably the ''Season7'' smartcard emulator. ...

International Olympiad In Informatics
The International Olympiad in Informatics (IOI) is an annual competitive programming and one of the International Science Olympiads for secondary school students. It is the second largest science olympiad, after International Mathematical Olympiad, in terms of number of participating countries (88 at IOI 2022). The first IOI was held in 1989 in Pravetz, Bulgaria. The contest consists of two days of computer programming/coding and problem-solving of algorithmic nature. To deal with problems involving very large amounts of data, it is necessary to have not only programmers, "but also creative coders, who can dream up what it is that the programmers need to tell the computer to do. The hard part isn't the programming, but the mathematics underneath it." Students at the IOI compete on an individual basis, with up to four students competing from each participating country (with 81 countries in 2012). Students in the national teams are selected through national computing contests, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

UTF-8
UTF-8 is a variable-width encoding, variable-length character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from ''Unicode'' (or ''Universal Coded Character Set'') ''Transformation Format 8-bit''. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes. It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that valid ASCII text is valid UTF-8-encoded Unicode as well. UTF-8 was designed as a superior alternative to UTF-1, a proposed variable-length encoding with partial ASCII compatibility which lacked some features including self-synchronizing code, self-synchronization and fully ASCII-compatible handling ...

ADE 651
The ADE 651 is a fake bomb detector produced by the British company Advanced Tactical Security & Communications Ltd (ATSC). Its manufacturer claimed it could detect bombs, guns, ammunition, and more from kilometers away. However, it was a scam, and the device was little more than a dowsing rod. Deception and its discovery ATSC claimed that the device could, from long range, effectively and accurately detect various types of explosives, drugs, ivory, and other substances. The device has been sold to 20 countries in the Middle East and Asia, including Iraq and Afghanistan, for as much as US$60,000 each. The Iraqi government is said to have spent GB£52 million on the devices. Investigations by the BBC and other organisations found that the device is little more than a "glorified dowsing rod" with no detecting ability. In January 2010, export of the device was banned by the British government and the managing director of ATSC was arrested on suspicion of fraud; in June 201 ...

VideoCrypt
VideoCrypt is a cryptographic, smartcard-based conditional access television encryption system that scrambles analogue pay-TV signals. It was introduced in 1989 by News Datacom and was used initially by Sky TV and subsequently by several other broadcasters on SES' Astra satellites at 19.2° east. Users Versions Three variants of the VideoCrypt system were deployed in Europe: VideoCrypt I for the UK and Irish market and VideoCrypt II for continental Europe. The third variant, VideoCrypt-S was used on a short-lived BBC Select service. The VideoCrypt-S system differed from the typical VideoCrypt implementation as it used line shuffle scrambling. * Sky NZ and Sky Fiji may use different versions of the VideoCrypt standard. * Sky NZ used NICAM stereo for many years until abandoning it when the Sky DTH technology started replacing Sky UHF. Operating principle The system scrambles the picture using a technique known as "line cut-and-rotate". Each line that made up each picture ( ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

Misc-fixed
''misc-fixed'' is a collection of monospace bitmap fonts that is distributed with the X Window System. It is a set of independent bitmap fonts which—apart from all being sans-serif fonts—cannot be described as belonging to a single font family. The misc-fixed fonts were the first fonts available for the X Window System. Their individual origin is not attributed, but it is likely that many of them were created in the early or mid 1980s as part of MIT's Project Athena, or at its industrial partner, DEC. The misc-fixed fonts are in the public domain. The individual fonts in the collection have a short name that matches their respective pixel dimensions, plus a letter that indicates a bold or oblique variant. They can also be accessed using their (much longer) X Logical Font Description string: The "6x13" font is usually also available under the alias "fixed", a font name that is expected to be available on every X server. The fonts originally covered only the ASCII repertoire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
