Re: Best books/sites to learn Python and Perl?

Re: How to read RS232 Data in Real Time on PC?

FTDI does make the best adapter chips. I swear buy them. Go to digikey or mouser and look for some RS232 connectors there. Also, look into Realterm for initial starting and basic tasks if you are on a windows system. I use both of them at work all the time.

Yes. If you are 32GB RAM with 1 processor the license for ESXi is free unless you want support. Does your budget include the Windows licensing? If it is $5,000 I would definitely use intel processor especially if you run ESXi. ESXi to me seems to be the pickiest about hardware for virtualization in ...

Except in this case, it is the lower-wattage unit with the lower temperature. So how do you separate cause from effect? Is the wattage lower *because* of the lower temperature? Or is the chip drawing less power due to natural variation from chip-to-chip, differences in the on-card BIOS, slight vari...

I would also test Heaven benchmark http://unigine.com/products/heaven/ or F@H. I find that sometimes Heaven will cause instability quicker than Furmark. Power usage is fairly similar though.
