Chess Problem Database Server
This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the Chess composer, problemist to find a solution to the posed situation, within the rules of chess, rather than to play games of chess from the beginning against an opponent. This is usually distinct from actually Computer chess, playing and analyzing games of chess. Many chess playing programs also have provision for solving some kinds of problem such as checkmate in a certain number of moves (Chess problem#Types of problem, directmates), and some also have support for helpmates and selfmates. Software for chess problems can be used for creating and solving problems, including checking the soundness of a concept and position, storing it in a database, printing and publishing, and saving a ...

1,4-Dichlorobenzene
1,4-Dichlorobenzene (1,4-DCB, ''p''-DCB, or ''para''-dichlorobenzene, sometimes abbreviated as PDCB or para) is an organic compound with the formula C6H4Cl2. This colorless solid has a strong odor. The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring. It is used as a disinfectant, pesticide, and deodorant, most familiarly in mothballs in which it is a replacement for the more traditional naphthalene because of naphthalene's greater flammability (though both chemicals have the same NFPA 704 rating). It is also used as a precursor in the production of the chemically and thermally resistant polymer poly(''p''-phenylene sulfide). Production ''p''-DCB is produced by chlorination of benzene using ferric chloride as a catalyst: :C6H6 + 2 Cl2 → C6H4Cl2 + 2 HCl The chief impurity is the 1,2 isomer. The compound can be purified by fractional crystallization, taking advantage of its relatively high melting poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Party Of German-speaking Belgians
The Party of German-speaking Belgians (german: Partei der Deutschsprachigen Belgier, PDB) was a regionalist political party active in the German-speaking Community of Belgium founded in 1971.

Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an appli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multitenancy
Software multitenancy is a software architecture in which a single instance of software runs on a server and serves multiple tenants. Systems designed in such manner are "shared" (rather than "dedicated" or "isolated"). A tenant is a group of users who share a common access with specific privileges to the software instance. With a multitenant architecture, a software application is designed to provide every tenant a dedicated share of the instance - including its data, configuration, user management, tenant individual functionality and non-functional properties. Multitenancy contrasts with multi-instance architectures, where separate software instances operate on behalf of different tenants. Some commentators regard multitenancy as an important feature of cloud computing. Adoption History of multitenant applications Multitenant applications have evolved from—and combine some characteristics of—three types of services: # Timesharing: From the 1960s companies rented spac ...

Pousette-Dart Band
The Pousette-Dart Band oo-sette(also known as PDB) was an American soft rock group active in the 1970s and early 1980s. Conceived in 1973 as a string band from Cambridge, Massachusetts, PDB comprised Jon Pousette-Dart, John Troy and John Curtis. With a shift to a more commercially oriented sound and a steady succession of additional personnel, the group went on to record a series of four albums for their label Capitol Records, two of which (''Amnesia'' and ''Pousette-Dart Band 3'') made the ''Billboard'' album chart. Their single "For Love" reached #83 on the ''Billboard'' singles chart. Although the band formally broke up in 1981, members reunited in 1991 for a series of concerts, and a "Best Of" album was released in 1994. Since then, collaborations among various former personnel have continued, with original members Pousette-Dart and Troy also launching solo careers. The song "Fall on Me" from the band's second album ''Amnesia'' was featured in the 11th episode of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
President's Daily Brief
The President's Daily Brief (PDB), sometimes referred to as the President's Daily Briefing or the President's Daily Bulletin, is a top-secret document produced and given each morning to the president of the United States; it is also distributed to a small number of top-level US officials who are approved by the president. It includes highly classified intelligence analysis, information about covert operations, and reports from the most sensitive US sources or those shared by allied intelligence agencies. At the discretion of the president, the PDB may also be provided to the president-elect of the United States, between election day and inauguration, and to former presidents on request. The PDB is produced by the director of national intelligence, and involves fusing intelligence from the Central Intelligence Agency, the Defense Intelligence Agency, the National Security Agency (NSA), the Federal Bureau of Investigation (FBI), the Defense Department, Homeland Security and other ...

President Of The United States
The president of the United States (POTUS) is the head of state and head of government of the United States of America. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. The power of the presidency has grown substantially since the first president, George Washington, took office in 1789. While presidential power has ebbed and flowed over time, the presidency has played an increasingly strong role in American political life since the beginning of the 20th century, with a notable expansion during the presidency of Franklin D. Roosevelt. In contemporary times, the president is also looked upon as one of the world's most powerful political figures as the leader of the only remaining global superpower. As the leader of the nation with the largest economy by nominal GDP, the president possesses significant domestic and international hard and soft power. Article II of the Constitution establ ...

Program Database
Program database (PDB) is a file format (developed by Microsoft) for storing debugging information about a program (or, commonly, program modules such as a DLL or EXE). PDB files commonly have a .pdb extension. A PDB file is typically created from source files during compilation. It stores a list of all symbols in a module with their addresses and possibly the name of the file and the line on which the symbol was declared. This symbol information is not stored in the module itself, because it takes up a lot of space. Applications When a program is debugged, the debugger loads debugging information from the PDB file and uses it to locate symbols or relate current execution state of a program source code. Microsoft Visual Studio uses PDB files as its primary file format for debugging information. Another use of PDB files is in services that collect crash data from users and relate it to the specific parts of the source code that cause (or are involved in) the crash. Micro ...

Promised Day Brigade
The Promised Day Brigade (abbreviated PDB; ar, لواء اليوم الموعود, Liwāʾ al-Yawm al-Mawʿūd), originally called the Muqawimun ( ar, المقاومون, al-Muqāwimūn, "Resisters"), was a Shi'a organization and was an insurgent group operating in Iraq during the war. In 2010, it was one of the largest and most powerful of what the US military call "Special Groups" in Iraq. The group was created as successor to Muqtada al-Sadr's Mahdi Army, which was Iraq's largest Shi'a militia until its disbanding in 2008, he also called on other Special Groups to join the brigade. Sadr had earlier already talked about the creation of a smaller guerrilla unit which would continue the Mahdi Army's armed activities but for the first time gave the organisation a name in November 2008 when he declared the creation of the Promised Day Brigade. Its activities have particularly increased since May 2009. The group's name is in reference to an alternate term for the Islamic Day of Ju ...
