 | Get ready for the new machines that are built to run WIndows 8. They will have a TPM installed that only has MS WIndows as a boot option. Booting from USB/CDROM will now be impossible if the BIOS vendor doesn't give you a way to disable the TPM or reload …  |
 | Re: bingo OK, I'm not going to do you homework for you. However, you should seriously consider running this program through a pretty printer. The formatting is so bad that it's a wonder you can read it yourself. And, so many variables names starting with "m" and "h"? Try giving the variables …  |
| | Re: sorting array Well, I'm not going to do your homework for you. However, you should look closely at your numeric sorting function. It sorts the numbers, but it's missing something important. |
 | At one time, I used to write a lot of FORTRAN code. In FORTRAN, many of these gems were ingrained in the way you were taught (i,j,k as integer variables, etc.). As I read through this, I had deja vu all over again with some of the code I've come … |
 | Actually, you should consider making the default lease time much shorter. More like 30 minutes. This does increase the number of lease renewals, but guarrantees that anyone who's not actively on the network gets their IP dropped for reuse by someone else. |

| | If you're running any of the Debian-based distros, an "apt-get install build-essential" will install everything you need to be able to develop C/C++ code on Linux. Then make sure that you use the CDT (C/C++ developer toolkit) version of Luna rather than the Java version to be able to find … |
 | If you're sending this with TCP sockets, the data will be converted to a stream of bytes and stuffed into the packet to be sent. There are no delimiters placed into the stream by the protocol. And, there's no guarrantee that you will get full MTU transfers (the Nagle algorithm … |
| | In this case, FORTRAN formats arrays in column-major order. That is, columns are adjacent in memory instead of the rows (C is row-major order). So, the developer is taking advantage of that knowledge in the way he/she is passing parameters. As you can see, this is really bad practice because … |
