Mod (video gaming)

A mod or modification is the alteration of content from a video game in order to make it operate in a manner different from its original version. Mods can be created for any genre of game but are especially popular in first-person shooters, role-playing games and real-time strategy games. Mods are made by the general public or a developer and can be entirely new games in themselves, but mods are not stand-alone software and require the user to have the original release in order to run. They can include new items, modded weapons, characters, enemies, models, textures, levels, story lines, music, money, armor, life and game modes. They can be single-player or multiplayer. Mods that add new content to the underlying game are often called partial conversions, while mods that create an entirely new game are called total conversions and mods that fix bugs only are called unofficial patches.

Games running on a personal computer are often designed with change in mind, allowing modern PC games to be modified by gamers without much difficulty. These mods can add extra replay value and interest. The Internet provides an inexpensive medium to promote and distribute mods, and they have become an increasingly important factor in the commercial success of some games. Developers such as id Software, Valve Software, Re-Logic, Bethesda Softworks, Firaxis, Crytek, The Creative Assembly and Epic Games provide extensive tools and documentation to assist mod makers, leveraging the potential success brought in by a popular mod like Counter-Strike.

Artà

Coordinates: 39°42′N 3°21′E / 39.700°N 3.350°E / 39.700; 3.350

Artà is one of the 53 independent municipalities on the Spanish Balearic island of Majorca. The small town of the same name is the administrative seat of this municipality in the region (Comarca) of Llevant.

Population

In 2008 the municipality of Artà had a population of 7,113 recorded residents within an area of 139.63 square kilometres (53.91 sq mi). This equates to 50.9 inhabitants per km². In 2006 the percentage of foreigners was 13.2% (890), of which Germans made up 3.9% (262). In 1991 there were still 136 illiterates in the municipality. 1,292 inhabitants had no education, 1,675 only a primary school certificate and 1,210 had secondary school leaving certificates. The official languages are Catalan and Spanish (Castilian). The Catalan dialect spoken on the island is known as Mallorquí.

Geography

Location

Artà lies in the northeast of the island of Majorca, around 60 km from the island's capital of Palma. The Massís d’Artà, the highest and most compact massif in the eastern mountain chain of the Serres de Llevant, occupies more than half the area of the municipality. The municipality is located on the western part of peninsula of Artà and is bordered in the west by the Bay of Alcúdia (Badia d’Alcúdia), and in the north by the Mediterranean sea where its coast lies opposite the neighbouring island of Minorca. The coast of Artà stretches for 25 kilometres and, so far, has escaped being developed. Particularly noteworthy are the beach and sand dune formations of sa Canova d’Artà, the flat coastal strip near the settlement of Colònia de Sant Pere, the high rocky coves of the Cap de Ferrutx and a large number of smaller bays that extend from s’Arenalet des Verger to Cala Torta.

ART image file format

ART is a proprietary image file format used mostly by the America Online (AOL) service and client software.

Technical details

The ART format (file extension ".art") holds a single still image that has been highly compressed. The format was designed to facilitate the quick downloading of images, among other things. Originally, the compression was developed by the Johnson-Grace Company, which was then acquired by AOL. When an image is converted to the ART format, the image is analyzed and the software decides what compression technique would be best. The ART format has similarities to the progressive JPEG format, and certain attributes of the ART format can lead to image quality being sacrificed for the sake of image compression (for instance, the image's color palette can be limited.)

Usage by AOL

The AOL service used the ART image format for most of the image presentation of the online service. In addition, the AOL client's web browser also automatically served such images in the ART format to achieve faster downloads on the slower dialup connections that were prevalent in those days. This conversion was done in the AOL proxy servers and could be optionally disabled by the user. This image conversion process effectively reduced the download time for image files. This technology was once branded as Turboweb and is now known as AOL TopSpeed.

Mod (Scotland)

A mod is a festival of Scottish Gaelic song, arts and culture. Historically, the Gaelic word mòd (Scottish Gaelic: [mɔːt̪]) refers to any kind of assembly. There are both local mods, and an annual national mod, the Royal National Mòd. Mods are run under the auspices of An Comunn Gàidhealach. The term comes from a Gaelic word for a parliament or congress in common use during the Lordship of the Isles.

A Mod largely takes the form of formal competitions. Choral events (in Gaelic, both solo and choirs), and traditional music including fiddle, bagpipe and folk groups dominate. Spoken word events include children and adult's poetry reading, storytelling and Bible reading, and categories such as Ancient Folk Tale or Humorous Monologue. Children can also present an original drama, and there are competitions in written literature.

Unlike the National Mòd, local mods usually only last a day or two. They attract a much smaller crowd and the only notable social event is the winners' ceilidh. As there are fewer competitions than in the National, this ceilidh is often more like a traditional ceilidh with dancing and guest singers between the winners' performances.

Luhn algorithm

The Luhn algorithm or Luhn formula, also known as the "modulus 10" or "mod 10" algorithm, is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, National Provider Identifier numbers in the US, and Canadian Social Insurance Numbers. It was created by IBM scientist Hans Peter Luhn and described in U.S. Patent No. 2,950,048, filed on January 6, 1954, and granted on August 23, 1960.

The algorithm is in the public domain and is in wide use today. It is specified in ISO/IEC 7812-1. It is not intended to be a cryptographically secure hash function; it was designed to protect against accidental errors, not malicious attacks. Most credit cards and many government identification numbers use the algorithm as a simple method of distinguishing valid numbers from mistyped or otherwise incorrect numbers.

Description

The formula verifies a number against its included check digit, which is usually appended to a partial account number to generate the full account number. This number must pass the following test:
