It provides relatively good performance by using a 'pass through' scheme, which executes guest code directly on the host. This avoids the performance hit suffered by VMMs that use emulation techniques to enable cross-platform virtualisation, such as running Intel guests on PowerPC hosts. text/html 2010-03-01T11:31:59+00:00 harvey http://www.datareign.co.uk/doku.php?id=palm_handheld_computers&rev=1267443119&do=diff These are still, in my opinion, the most user friendly PDAs. In addition to Palm themselves, companies like Alphasmart and Sony have produced devices which use the Palm Operating System (also known as PalmOS). PalmOS provides an effective and well debugged process for storing an image of the PDA's memory on a host computer's disk. Called 'Hotsync', this stores all the basic data held in the PDA to a user directory on the host. text/html 2010-03-01T11:10:29+00:00 harvey http://www.datareign.co.uk/doku.php?id=hardware&rev=1267441829&do=diff * Linksys NSLU2 Pocket sized network attached storage controller with many other uses. * Hardware Troubleshooting Tips * Palm Handheld Computers text/html 2010-02-06T10:49:04+00:00 harvey http://www.datareign.co.uk/doku.php?id=wxformbuilder&rev=1265453344&do=diff wxFormBuilder is still evolving and it's worth paying regular visits to the project's home page. As of February 2010, the project recommends that the generated code should not be edited to add functionality outside of wxFormBuilder, as the generated code is replaced at each pass. Instead, the form builder's “generate inherited class” functionality should be used. text/html 2010-02-06T10:37:40+00:00 harvey http://www.datareign.co.uk/doku.php?id=codeblocks&rev=1265452660&do=diff Code::Blocks can be used for development with a wide range of languages and libraries.

That's because some pages are placeholders, to remind us that we need to add that information, and we only have a limited amount of time to work on them.

A colleague needed to find the length of a particular line in a file. He discovered that using 'wc' gave the wrong result (as in “head -2 filename | tail -1 | wc -c”). Here's what he came up with instead. Note the parentheses...
