Simple Tutorial on Compiling C programs with GCC

GCC is the GNU c compiler that can does a lot of heavy lifting in the programming worlds.

The basic format for compiling a Hello World program is:

gcc hello.c -o hello

In this statement 'hello.c' is the program, '-o' is an option and 'hello' will be the name of the executable program. The '-o' option just specifies that compiled version of your program will be saved to an another filed called 'hello'. If you exclude this option, the the compiler will save to a default 'a.out' file.

Breif Review of Harbor Freight 1/2 inch Air Impact Wrench

Having never bought anything from Harbor Freight (Fright), I decided to grab this ultra inexpensive air tool to make quick work of rotating tires. For less than $20 bucks, I thought I should give it a try. The bottom line was - it did work fine, but seemed to lack torque. I guess this shouldn't be a surprise, but I really wonder if it really has a max torque of 250 ft-lbs.

In the end, I did return the item without any problems, so no major complaints, but probably not the best tool for stubborn, rusted bolts. Considering higher end air impact wrenches are many times the price ( over $100 ) of this one, one can't be too critical.
