  • Did you try the "Secure Empty Trash" option? In the Finder it's under the Finder menu item, just below the Empty Trash option. That should allow you to delete files that have permissions problems. It'll ask you for your password before it does it.

  • First Apple computer would be an Apple II, bought around 1980. First Mac was a Powerbook Duo 230, bought around 1993. I later had it converted to a 2300, going from a 33 Mhz 68030 to a 100 Mhz PPC 603e.

  • Here's a page about the financial support at the department I went to, UNC computer science: http://www.cs.unc.edu/WhyJoinUs/Grad...dmissions.html I was there a long time ago, but the assistantship money was generally enough to live on, if you…

  • Double click on the message header so the message shows up in its own window. Then you can select "View ->Internet Headers". You can also see the headers by selecting "View -> Source", along with the raw message.

  • Unfortunately I'm not going to make it to Siggraph (for the first time in years). But I think a dual 2.5 GHz with the new Nvidia graphics card is quite a compelling package. Throw in two 30" displays and you really got something. I have no compla…

  • I've got a pair of JM Lab Electra 915.1's that I really like. That particular model has been discontinued, but now they have the 926's. Here's a used pair of 926's for sale on Audiogon for $2300: http://cls.audiogon.com/cgi-bin/cls....ull&…

  • Another Datsun in da house. It was a 1978 Datsun 810 station wagon. My dad gave it to me my sophomore year in college, 1985. It was a good car. 3 liter, 6 cylinder engine with a 4 speed manual transmission.

  • Here are some pictures of my office. I have a dual G5 driving two displays, an Apple Cinema Display and an NEC projector. I also have a 500 Mhz Powerbook, a 40 gig iPod and an iSight. I got rid of the Linux box and its LCD monitor in the pi…

  • I'm a computer scientist. I do research in medical visualization, image processing and computer graphics at NIH. Got my degree from the same august department as Kickaha will.
    in What's your profession Comment by davechen February 2004
  • Yeah, it's a relatively new thing. g++ 3.3 started complaining about obsolete headers when I used , then I had the same problem. Using it couldn't find the type without the "std::". Note that if you put a "using namespace std" at the begining …

  • The amazing thing about Berkeley is the quality of the research. 35 out of the 36 departments there are ranked in the top ten. I went there as an undergrad (from out of state) and then went to UNC as a grad student, and the difference was prof…

  • I think for C++ strings you're supposed to do this: Code: #include string.h gets you the C string functions, not the C++ string type. Also in your C++ code you need to either declare the string like this: Code: std::string foo; …
    in String.h and g++/XCode trouble Comment by davechen November 2003
  • Yeah, those links do a better job of explaining the problem. Basically, the boundary of a character or polygon never coincides with the pixel boundaries. So trying to reconstruct point samples of the polygon is going to result in artifacts. It …

  • Quote: Originally posted by drumsticks What exactly does anti-aliasing mean in this context? Technically, I mean. I know it smooths texts and lines, so that words and lines are less jaggy, but how does it relate to the usual aliasing effect? T…

    in benefits of using GCC 3.3 Comment by davechen August 2003
  • gcc 3.3 definitely produces faster code, at least for my stuff. My code is mostly just generic sparse matrix solving in C++, and it seems to run about twice as fast using 3.3 versus 3.1. I haven't looked at the assembly code to figure out why, tho…

  • There's a web site devoted to using GPUs for general processing at UNC (my alma mater): http://wwwx.cs.unc.edu/~harrism/gpgpu/ And there's a session at Siggraph devoted to the topic too: http://www.siggraph.org/s2003/confer.../papers12.html…

  • Yeah, neither Camino nor Mozilla work for me. Mozilla won't start. Camino runs and says it loads a page, but the window is empty.
