Instead of carrying my SD card in my camera, I left it sticking out of the side of my laptop, presumably intending to do something with the photos on it eventually. On my flight home from Boston, the predictable thing happened: as I got up out of my seat, the machine fell out of my lap, and as the machine hit the ground, the SD card hit first, and was destroyed. text/html 2013-01-30T04:04:46-04:00 joshuawise http://www.joshuawise.com/horndis?rev=1359536686&do=diff HoRNDIS (pronounce: “horrendous”) is a driver for Mac OS X that allows you to use your Android phone's native USB tethering mode to get Internet access. It is known to work with Mac OS X versions 10.6.8 (Snow Leopard) through 10.8.2 (Mountain Lion), and has been tested on a wide variety of phones. Although you should be careful with all drivers that you install on your computer, HoRNDIS has been tested at least well enough for the author (and many others) to run full time on their own personal… text/html 2013-01-16T18:25:35-04:00 joshuawise http://www.joshuawise.com/c-brainteasers?rev=1358378735&do=diff Here's a small list of C brainteasers that a few friends and I came up with and/or found. (All problems, except where specified, in C99.) * Can you write some C of the form sizeof ( ... printf(“hey!\n”) ... ) which results in hey! being printed? * No, you may not put a close paren in the first .... * sizeof comes in two forms in C -- sizeof ( TYPENAME ), and sizeof EXPRESSION. Can you do it with both forms? * Can you do it without emitting any warnings? text/html 2012-12-29T02:11:04-04:00 joshuawise http://www.joshuawise.com/projects?rev=1356765064&do=diff Here is a list of projects that I have involved myself in at one point or another. This list is incomplete (indeed, you might find that a recurring theme on this site), but you might find it useful for getting an idea of things that I'm interested in. This is roughly sorted from most recent to most ancient; at the very top are recent actions I've taken on GitHub, which might give a better view of what I've been spending my time on lately. text/html 2012-12-19T05:11:38-04:00 joshuawise http://www.joshuawise.com/wireless-whitelist?rev=1355911898&do=diff Chris Lu and I originally wrote -- and did -- this around December, 2005. The article has been preserved for posterity. New since then is Tiido Priimägi's version of this hack, which takes it to another level; see below! As the authors of this article discovered unintentionally, recent HP laptops (including the HP tc1100 tablet PC and the HP zv5460us desktop replacement) have a wireless whitelist built into the BIOS similar to that found by Matthew Garrett on IBM Thinkpads.
