Cockroach Labs

Cockroach Labs is a computer software company that develops infrastructure solutions for businesses. It is best known for CockroachDB, a database that has been compared to Google's Spanner database. CockroachDB is an open-sourced software project that is designed to store copies of data in multiple locations in order to deliver requested data when needed. It is described as a scalable, consistently-replicated, transactional datastore.

History

Cockroach Labs was founded in 2015 by ex-Google employees Spencer Kimball, Peter Mattis, and Ben Darnell. Prior to Cockroach Labs, Kimball and Mattis were key members of the Google Colossus team while Darnell was a key member of the Google Reader team. While at Google, all three had previously used BigTable and were acquainted with its successor, Spanner. After leaving Google, they wanted to design and build something similar for companies outside of Google. By June 2015, the company had nine engineers working on its CockroachDB software.

C mathematical functions

C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. All functions use floating point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).

Overview of functions

Most of the mathematical functions are defined in math.h (cmath header in C++). The functions that operate on integers, such as abs, labs, div, and ldiv, are instead defined in the stdlib.h header (cstdlib header in C++).

Any functions that operate on angles use radians as the unit of angle.

Not all of these functions are available in the C89 version of the standard. For those that are, the functions accept only type double for the floating-point arguments, leading to expensive type conversions in code that otherwise used single-precision float values. In C99, this shortcoming was fixed by introducing new sets of functions that work on float and long double arguments. Those functions are identified by f and l suffixes respectively.

Labëria

Labëria is a historic region that is roughly situated in Southern Albania. Its inhabitants are known as Labs (referred to as Albanian: sing: Lab, pl. Lebër, also dial. sing.: Lap in Albanian and Greek: Λιάπης, Liapis in Greek) and its boundaries reach from Vlorë to Himara in the south, to the Greek border near Sarandë, incorporating the Kurvelesh region of Gjirokastër District and extending east to the city of Tepelenë.

Labëria is culturally distinguishable from the rest of Albania in its traditions and folklore. The Labs were warlike pastoral people who lived mainly in the mountains of Kurvelesh, Progonat and Vlorë during the Ottoman invasion of Albania. However, due to mass migrations to urban areas following World War II, the population is now concentrated in the cities of Vlorë, Tepelenë, Gjirokastër and Sarandë.

Historically the Labs were followers of the Eastern Orthodox Christianity but many converted to Islam during Ottomon rule, with the bulk of conversion occurring in the 18th century. Conversions were especially intense during years of conflict between Orthodox Russia and the Ottoman Empire, during which some pressure was applied on Orthodox Christians by Ottoman rulers, including even low-scale forced conversion of villages, contradicting the official Ottoman tolerance for Christians. Additional reasons for conversion included discrimination and exploitation of Christians by Ottoman rulers, the previous patterns of conversion between different Christian sects and the diverse pre-Ottoman distribution of Christian faiths in the region (including Orthodoxy, Catholicism, Bogomolism and even Arianism), the poll tax which only Christians had to pay, the poverty of the church, the mass illiteracy of priests and the fact that the language of worship was not the Albanian vernacular. Tradition holds that a mass conversion of Labs occurred during a famine in which the bishops of Himara and Delvina refused to let the Labs break fast and drink milk.

Cockroach

Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests.

The cockroaches are an ancient group, dating back at least as far as the Carboniferous period, some 320 million years ago. Those early ancestors however lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of Hemiptera; they have chewing mouthparts and are likely among the most primitive of living neopteran insects. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropical heat. Tropical cockroaches are often much bigger than temperate species, and, contrary to popular opinion, extinct cockroach relatives and 'roachoids' such as the Carboniferous Archimylacris and the Permian Apthoroblattina were not as large as the biggest modern species.
