From a question on the Practice C test from GeekInterview, why is the size of ptr1 2, while ptr2 and ptr3 are size of 4?
main() { char near * near *ptr1; char near * far *ptr2; char near * huge *ptr3; printf("%d %d %d",sizeof(ptr1),sizeof(ptr2),sizeof...

A byte is a byte is a byte -- 8 bits, no more, no less .
The size of numeric types is generally a multiple of the machine word size.

Looking at the properties for a windows file I get two attributes, Size & Size on disk and Size on disk is always larger.
What do these two metrics mean?

It's because the 4 byte ints are aligned to a 4 byte boundry, so there are 2 bytes of padding after bfType -1 : bfType +2 -3 : <padding> +4 -7: bfSize +8 -9: bfReserve1 +10 -11: bfReserve2 +12 -15 .

I paid $59.95 for Vimeo Plus only to find that there is a 1 gig limit on video size.
I have a 4 gig mp4 video file that I shot with the HD Flip Mino. How do I reduce it to no more than 1 gig without losing too much quality?
Answer Snippets (Read the full thread at superuser):
You can try using something such as ffmpeg or mencoder to reencode it with a lower bitrate, e.g.:
# Calculate the bitrate you need by dividing 1 GB by the video length in seconds # So, for a video of length 16:40 (1000 seconds), use a bitrate of 1 bytes... .
