Same numbers, right? Apparently showing only 30 MB free.

Next line from free:

Shows that you actually have 825 MB available.

The OS is just using the rest of it to help speed things up by caching
things (disk reads, for example) in memory.

The moment a real program needs more memory, then it'll get it - up to
825 MB of it.*
