Archive

An archive is an accumulation of historical records or the physical place they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity.

In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost always unique, unlike books or magazines for which many identical copies exist. This means that archives are quite distinct from libraries with regard to their functions and organization, although archival collections can often be found within library buildings.

Archive file

An archive file is a file that is composed of one or more computer files along with metadata. Archive files are used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space. Archive files often store directory structures, error detection and correction information, arbitrary comments, and sometimes use built-in encryption.

Applications

Archive files are particularly useful in that they store file system data and metadata within the contents of a particular file, and thus can be stored on systems or sent over channels that do not support the file system in question, only file contents – examples include sending a directory structure over email.

Beyond archival purposes, archive files are frequently used for packaging software for distribution, as software contents are often naturally spread across several files; the archive is then known as a package. While the archival file format is the same, there are additional conventions about contents, such as requiring a manifest file, and the resulting format is known as a package format. Examples include deb for Debian, JAR for Java, and APK for Android.

Hydro (fuel-station chain)

Hydro was a chain of fuel stations throughout Sweden owned by Statoil. The chain had more than 500 stations, as well as some unmanned Uno-X stations. The company also operated in retailing natural gas, electricity and heating oil.

History

The Hydro chain was created in the late 1980s when Norsk Hydro bought the Mobil stations in Norway, Sweden and Denmark to transform itself to a vertically integrated petroleum company. The stations were rebranded Hydro in all three countries. In 1995 the Norwegian and Danish stations were converted to Hydro Texaco when Hydro merged its stations in the two countries with Texaco's stations. In 2007 the ownership of Hydro was transferred to StatoilHydro when Norsk Hydro's oil and gas division merged with Statoil. When StatoilHydro was renamed Statoil in November 2009, the use of the Hydro-brand was discontinued and ownership of the Hydro filling stations was transferred to St1.

Haazareth Three

The Haazareth Three debuted in Fantastic Four Vol 3 #69 (2003). They operate out of the hellish realm ruled by Mephisto. They are a trio of demons with whom Doctor Doom made a pact (seen in the Unthinkable story arc). They made a deal with Doom; if he sacrifices something of irreplaceable value, they would provide him with the magical powers he would have possessed if he had chosen to devote his life to studying magic over science. Doom does, killing his childhood sweetheart, Valeria. The demons come through with the deal.

Hack

Hack is a mutant whose first appearance was in Excalibur vol. 2 #2. He was one of the few survivors after Cassandra Nova programmed her Wild Sentinels to decimate the island nation of Genosha, killing over 16 million mutants. He found other survivors and allied himself with Unus the Untouchable and his gang. He was a very valuable asset on the island since all forms of electronic communication were eradicated or made useless by the resulting electro-magnetic damage. Inside of the gang, he became close friends with Hub and the two of them began to doubt if Unus' exclusive, clique-like strategy was the best way. Hack was gifted with a finely tuned form of telepathy that allowed him to "hack" into almost any mind.
