  2. Delimited continuation - Wikipedia

    en.wikipedia.org/wiki/Delimited_continuation

    The reset delimits the continuation that shift captures (named by k in this example). When this snippet is executed, the use of shift will bind k to the continuation (+ 1 []) where [] represents the part of the computation that is to be filled with a value. This continuation directly corresponds to the code that surrounds the shift up to the reset.

  3. Timeout (computing) - Wikipedia

    en.wikipedia.org/wiki/Timeout_(computing)

    Specific examples include: In the Microsoft Windows and ReactOS [2] command-line interfaces, the timeout command pauses the command processor for the specified number of seconds. [3] [4] In POP connections, the server will usually close a client connection after a certain period of inactivity (the timeout period). This ensures that connections ...

  4. Watchdog timer - Wikipedia

    en.wikipedia.org/wiki/Watchdog_timer

    Simple analog watchdog timer Example timing diagram for analog WDT shown above. Four timely kick pulses keep V C below V TH. When kicks cease, V C rises above V TH and causes a timeout. Analog WDTs have a kick input and timeout output, but lack the clock input signal found in digital electronic watchdogs.

  5. Selenium (software) - Wikipedia

    en.wikipedia.org/wiki/Selenium_(software)

    Selenium Remote Control was a refactoring of Driven Selenium or Selenium B designed by Paul Hammant, credited with Jason as co-creator of Selenium. The original version directly launched a process for the browser in question, from the test language of Java, .NET, Python or Ruby.

  6. Object pool pattern - Wikipedia

    en.wikipedia.org/wiki/Object_pool_pattern

    One example is the .NET Framework Data Provider for SQL Server. As SQL Server database connections can be slow to create, a pool of connections is maintained. Closing a connection does not actually relinquish the link to SQL Server. Instead, the connection is held in a pool, from which it can be retrieved when requesting a new connection.

  7. Database connection - Wikipedia

    en.wikipedia.org/wiki/Database_connection

    An application failure occurs when the connection pool overflows. This can occur if all of the connections in the pool are in use when an application requests a connection. For example, the application may use a connection for too long when too many clients attempt to access the web site or one or more operations are blocked or simply inefficient.

  8. HTTP persistent connection - Wikipedia

    en.wikipedia.org/wiki/HTTP_persistent_connection

    However, the default connection timeout of Apache httpd 1.3 and 2.0 is as little as 15 seconds [6] [7] and just 5 seconds for Apache httpd 2.2 and above. [8] [9] The advantage of a short timeout is the ability to deliver multiple components of a web page quickly while not consuming resources to run multiple server processes or threads for too ...

  9. Diode logic - Wikipedia

    en.wikipedia.org/wiki/Diode_logic

    In one unusual design, small selenium diode discs were used with germanium transistors. The recovery time of the very slow selenium diodes caused a glitch on the inverter output. It was fixed by placing a selenium diode across the base-emitter junction of the transistor making it think it was a selenium transistor (if there could ever be one).
