how to install gcc on windows 7 machine?
...
EDIT Since not so recently by now, MinGW-w64 has "absorbed" one of the toolchain building projects. The downloads can be found here. The installer should work, and allow you to pick a version that you need.
Note the Qt SDK comes with the same toolchain. So if you ar...

dd: How to calculate optimal blocksize? [closed]
...enough block size lets dd do a good job, and the differences between, say, 64 KiB and 1 MiB are minor, compared to 4 KiB versus 64 KiB. (Though, admittedly, it's been a while since I did that. I use a mebibyte by default now, or just let dd pick the size.)

For a more convenient installer, you may want to use the
apt-cyg package manager. Its syntax

Why does an NSInteger variable have to be cast to long when used as a format argument?
...
You get this warning if you compile on OS X (64-bit), because on that platform NSInteger is defined as long and is a 64-bit integer. The %i format, on the other hand, is for int, which is 32-bit. So the format and the actual parameter do not match in size.
Since NSInte...
