  2. Timestamp - Wikipedia

    en.wikipedia.org/wiki/Timestamp

    Some file archivers and some version control software, when they copy a file from some remote computer to the local computer, adjust the timestamps of the local file to show the date/time in the past when that file was created or modified on that remote computer, rather than the date/time when that file was copied to the local computer.

  3. Trimming (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Trimming_(computer...

    For example, PHP and Python allow this optional parameter, while Pascal and Java do not. With Common Lisp's string-trim function, the parameter (called character-bag ) is required. The C++ Boost library defines space characters according to locale , as well as offering variants with a predicate parameter (a functor ) to select which characters ...

    en.wikipedia.org/wiki/Presentation_timestamp

    The master time base may be one of the N decoders' clocks, the data source’s clock, or it may be some external clock. [1] A transport stream may contain multiple programs and each program may have its own time base. The time bases of different programs within a transport stream may be different.

  5. Tracing garbage collection - Wikipedia

    en.wikipedia.org/wiki/Tracing_garbage_collection

    In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them.

  6. Trim (computing) - Wikipedia

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

    TRIM can take a lot of time to complete, depending on the firmware in the SSD, and may even trigger a garbage collection cycle. [ citation needed ] This penalty can be minimized in solutions that do batched TRIMs and/or periodic TRIMs, rather than trimming upon every file deletion , by scheduling such batch jobs for times when system ...

  7. Reference counting - Wikipedia

    en.wikipedia.org/wiki/Reference_counting

    Bacon describes a cycle-collection algorithm for reference counting with similarities to tracing collectors, including the same theoretical time bounds. It is based on the observation that a cycle can only be isolated when a reference count is decremented to a nonzero value.

  8. Date-time group - Wikipedia

    en.wikipedia.org/wiki/Date-time_group

    In communications messages, a date-time group (DTG) is a set of characters, usually in a prescribed format, used to express the year, the month, the day of the month, the hour of the day, the minute of the hour, and the time zone, if different from Coordinated Universal Time (UTC).

  9. Java syntax - Wikipedia

    en.wikipedia.org/wiki/Java_syntax

    A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.
