Alot of this pertains to unix systems Autoconf, automake,libtool: http://sources.redhat.com/autobook/autobook/autobook.html#SEC_Top C++ const correctness http://www.linuxjournal.com/article.php?sid=7629 dlopen mini-howto http://www.tldp.org/HOWTO/C++-dlopen/ C++ FAQ lite...

My opinion is that you should install linux. I have a computer that Windows 98 will crash on either during the install or a few minutes after the first boot up after an installation. It is an alleged hard drive problem (if it crashes during installation ) or an alleged video driver problem (if...

Instead of learning a plethora of languages, consider using C++ and learn about things you can do with C++. There are lots of interesting technologies e.g. sockets, GUI toolkits, or OpenGL that you could learn. You could also use C++ to practice techniques like "design patterns" that would...

If the problem is your integration scheme then have you considered using a Verlet algorithm? The error in a Verlet integration is 4th power of the time step. You can google for Leap Frog and "velocity verlet" algorithms in addition to the plain verlet algorithm if it looks like you can adapt...

Have you considered using quaternions to do the rotation? If you search for the phrase "The main problem with encoding a rotation" in this document http://www.sjbrown.co.uk/quaternions.html it will explain a little why I think using quaternions might help. If you find a solution to your...

Using "long long" is the easiest but if you want numbers greater than 1019 and your processor has SSE2 instructions then you can gain access to 128 bit ( 1038 )integer operations. http://www.intel.com/design/pentium4/manuals/253665.htm

To be more explicit, maximal with respect to connectedness. In other words a maximal connected subgraph is connected and contains as many edges and vertices as possible. http://members.cox.net/gradyfield/graph.png In the picture, the subgraph with Vertices={A,B,C,D} and...

Poisson is a suitable approximation to binomial when \lambda is small enough and n is large enough that \left(1-\frac{\lambda}{n}\right)^n\approx e^{-\lambda}, \frac{n(n-1)\cdots(n-i+1)}{n^i}\approx 1 and \left(1-\frac{\lambda}{n}\right)^i\approx 1. Poisson looks fine for this.

I got problems with fonts showing up as boxes. I recently copied all of my fonts from windows xp into the fonts directory in windows 98. Thats all I can think of that would be the problem. But going through and looking at the fonts with character map, none of them are screwed up. Does anyone...

Ok, I fixed 1-4. 5 I'll fix later. 6&7 I'm not worried about right now, but I didn't know that was there so thanks for pointing them out and I'll fix them when i have some more time. 8 is a feature, and I prettied up the output of ? so 9 is "fixed". Thanks for all of the input, dduardo.

I just uploaded a project to sourceforge. I got the idea from a windows program that I used in the lab this semester. The program is simple, but it still does more than the windows program I had to use (yay), and you don't have to use a mouse. The project is at...

Copying and pasting the phrase "thankfully it's a single slot solution" directly from the article you linked to might have tipped you off that prior to the release of your card, there were cards that were not "single slot solutions", but it did not tip you off. I posted that on July 18, 4...

I wonder why 99mTc has an "m" in the mass number. Does anyone know?

It depends on which organ they were looking at. Different organs take up different chemicals better than others. 131I, 132I, and 123I are all used, but for instance 131I has a half-life of 8 days which is longer than any test will last so its more ideal to use 123I. Different compounds...

I have this book, it is very good. I think it is just what you need.
