Texas Instruments Signing Key Controversy
The Texas Instruments signing key controversy resulted from Texas Instruments' (TI) response to a project to factorize the 512-bit RSA cryptographic keys needed to write custom firmware to TI devices. Project In July 2009, Benjamin Moody, a United-TI forum user, published the factors of a 512-bit RSA key used to sign the TI-83+ series graphing calculator. The discovery of the private key would allow end users to flash their own operating systems onto the device without having to use any special software. Moody used two free implementations of the general number field sieve, msieve and ggnfs; the computation took 73 days on a 1.9 GHz dual-core processor. This demonstrates the progress of hardware development: the factorization of the similar 512-bit RSA-155 in 1999 using the same algorithm required a large dedicated research group, 8000 MIPS-years of computing time, and a Cray C916 supercomputer. In response, members of the wider TI graphing calculators community (at yAr ...

Website
A website (also written as a web site) is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Examples of notable websites are Google Search, Google, Facebook, Amazon (website), Amazon, and Wikipedia. All publicly accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a intranet, private network, such as a company's internal website for its employees. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. User (computing), Users can access websites on a range of devices, including desktop computer, desktops, laptops, tablet computer, tablets, and smartphones. The application software, app used on these devices is called a Web browser. History ...

TI-73
The TI 73 series is a series of graphing calculators made by Texas Instruments, all of which have identical hardware. The original TI-73 graphing calculator was originally designed in 1998 as a replacement for the TI-80 for use at a middle school level (grades 6-9). Its primary advantage over the TI-80 is its 512 KB of flash memory, which holds the calculator's operating system and thereby allows the calculator to be upgraded. Other advantages over the TI-80 are the TI-73's standard sized screen (as opposed to the TI-80's smaller screen), the addition of a link port, 25 KB of RAM (as compared to the TI-80's 7 KB of RAM), and a faster 6 MHz Zilog Z80 processor (as compared with the TI-80's 980 kHz proprietary processor). The TI-73 also uses the standard 4 AAA batteries with a lithium backup battery (instead of the TI-80's 2 CR2032 lithium batteries). In 2003, the TI-73 was redesigned with a new body shape and redesignated the TI-73 Explorer to indicate its currently intended ...

TI-92 Series
The TI-92 series of graphing calculators are a line of calculators produced by Texas Instruments. They include: the TI-92 (1995), the TI-92 II (1996), the TI-92 Plus (1998, 1999) and the Voyage 200 (2002). The design of these relatively large calculators includes a QWERTY keyboard. Because of this keyboard, it was given the status of a "computer" rather than "calculator" by American testing facilities and cannot be used on tests such as the SAT or AP Exams while the similar TI-89 can be. TI-92 The TI-92 was originally released in 1995, and was the first symbolic calculator made by Texas Instruments. It came with a computer algebra system (CAS) based on Derive, geometry based on Cabri II, and was one of the first calculators to offer 3D graphing. The TI-92 was not allowed on most standardized tests due mostly to its QWERTY keyboard. Its larger size was also rather cumbersome compared to other graphing calculators. In response to these concerns, Texas Instruments introduced th ...

Hexadecimal
In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15. Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, a number of ...

TI-83+
The TI-83 series is a series of graphing calculators manufactured by Texas Instruments. The original TI-83 is itself an upgraded version of the TI-82. Released in 1996, it was one of the most popular graphing calculators for students. In addition to the functions present on normal scientific calculators, the TI-83 includes many features, including function graphing, polar/parametric/sequence graphing modes, statistics, trigonometric, and algebraic functions, along with many useful applications. Although it does not include as many calculus functions, applications and programs can be written on the calculator or loaded from external sources. The TI-83 was redesigned twice, first in 1999 and again in 2001. TI replaced the TI-83 with the ''TI-83 Plus'' in 1999. The 2001 redesign introduced a design very similar to the TI-73 and TI-83 Plus, eliminating the sloped screen that had been common on TI graphing calculators since the TI-81, and included Flash memory, enabling the device's o ...

DMCA 512
The Online Copyright Infringement Liability Limitation Act (OCILLA) is United States federal law that creates a conditional 'safe harbor' for online service providers (OSP) (a group which includes internet service providers (ISP) and other Internet intermediaries) by shielding them for their own acts of direct copyright infringement (when they make unauthorized copies) as well as shielding them from potential secondary liability for the infringing acts of others. OCILLA was passed as a part of the 1998 Digital Millennium Copyright Act (DMCA) and is sometimes referred to as the "Safe Harbor" provision or as "DMCA 512" because it addeSection 512to Title 17 of the United States Code. By exempting Internet intermediaries from copyright infringement liability provided they follow certain rules, OCILLA attempts to strike a balance between the competing interests of copyright owners and digital users. Overview The 1998 DMCA was the U.S. implementation of the 1996 WIPO Copyright Treaty ...

Misrepresentation
In common law jurisdictions, a misrepresentation is a false or misleading '' R v Kylsant'' 931/ref> statement of fact made during negotiations by one party to another, the statement then inducing that other party to enter into a contract. The misled party may normally rescind the contract, and sometimes may be awarded damages as well (or instead of rescission). The law of misrepresentation is an amalgam of contract and tort; and its sources are common law, equity and statute. In England and Wales, the common law was amended by the Misrepresentation Act 1967. The general principle of misrepresentation has been adopted by the United States and other former British colonies, e.g. India. Representation and contract terms A "representation" is a pre-contractual statement made during negotiations. If a representation has been incorporated into the contract as a term, then the normal remedies for breach of contract apply. Factors that determine whether or not a representation has beco ...

Pro Bono
( en, 'for the public good'), usually shortened to , is a Latin phrase for professional work undertaken voluntarily and without payment. In the United States, the term typically refers to provision of legal services by legal professionals for people who are unable to afford them. is also used in the United Kingdom to describe the central motivation of large organizations, such as the National Health Service and various NGOs which exist "for the public good" rather than for shareholder profit, but it equally or even more applies to the private sector where professionals like lawyers and bankers offer their specialist skills for the benefit of the community or NGOs. Legal counsel Pro bono legal counsel may assist an individual or group on a legal case by filing government applications or petitions. A judge may occasionally determine that the loser should compensate a winning pro bono counsel. Philippines In late 1974, former Philippine Senator Jose W. Diokno was released from ...
