Uit Wikipedia, de vrije encyclopedie Ga naar: navigatie, zoeken RJ-45 connectors Een RJ-45 connector (RJ = Registered Jack, geregistreerde insteekplug) is een 8-polige modulaire connector die vooral gebruikt wordt voor twisted pair ethernetverbindingen en ISDN-telefonie, maar ook voor RS-232. Afhankelijk van de toepassing is een andere benaming 8P8C (8 positions/posities, 8 conductors/geleiders), 8P6C of 8P4C [...]

1000BASE-T capable PCI-X network interface card from Intel 1000BASE-T (also known as IEEE 802.3ab) is a standard for gigabit Ethernet over copper wiring. Each 1000BASE-T network segment can be a maximum length of 100 meters (328 feet), and must utilize “Category 5″ cabling at a minimum. Category 5e cable or Category 6 cable may also [...]

pip is a replacement for easy_install. It uses mostly the same techniques for finding packages, so packages that were made easy_installable should be pip-installable as well. pip is meant to improve on easy_install. Some of the improvements: * All packages are downloaded before installation. Partially-completed installation doesn’t occur as a result. * Care is taken [...]

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.4/site-packages (or whatever your platform’s standard location is), it’s easy to end [...]

It is designed to upload files to, and run shell commands on, a number of servers in parallel or serially. These commands are grouped in tasks (regular python functions) and specified in a ‘fabfile.’ This is called remote automation, and the primary use case is deploying applications to multiple similar hosts. Although it is easier [...]

IEEE standard 829-1998 covers test plans in section 4, test designs in section 5, test cases in section 6, test logs in section 9, test incident reports in section 10, test summary reports in section 11, and other matherial that I have decided not to summarise in the other sections. Beware. This is only a [...]

Larger is not always better. We suggest that you tune your configuration until it’s “good enough,” then leave it alone unless you have reason to believe you’re forgoing a significant performance improvement. You might also want to revisit it when you change your queries or schema. we don’t have a one-size-fits-all “best configuration file” for, [...]
