I was wondering if anybody here knows of a good reference like a textbook perhaps to study finite fields and vector spaces over those finite fields. I thought maybe these topics are relevant to computer science (like cryptography and error detection/correction codes) so there may be a well known text or something. Every time I search anywhere I keep getting "finite DIMENSIONAL vector spaces". I can imagine most of the theory is the same as real/complex vector spaces but there are some subtle differences which I want to explore. Thanks! - Looking for Wisdom and Insight!

Sometimes you have files that you want to open them but you don't know the extension! How would you open them? for example some tmp files or someone who Gziped a file, but didn't added the extension... or if someone used binhex on it and you extract the hqx file but don't know what to do with the file.. How would you find the extension? 190.60.93.218 ( talk) 18:04, 17 February 2012 (UTC)
file
from
gnuwin32.sf.net. It is a command line application, though, so to get the most use out of it, you'll want to add the directory of executables it creates (by default %programfiles%\GnuWin32\bin
[or %programfiles(x86)%\GnuWin32\bin
for a 64-bit system, since it's a 32-bit binary]) to
your path. Then to utilize it, at least in recent versions of Windows, you can SHIFT+right_mouse_click on a directory to get a convenient 'Open command window here', and run file nameOfFile

No, no no.. I don't need to know what is the extension of the file, becuase the file itself has .001 extension. and neither wnrar, vlc, notepad obviously opens it, it says some text. and beyond that it's binary. it's a strange format... meh.. I'll try to use that build that finds file types.. though. 190.158.184.192 ( talk) 20:58, 19 February 2012 (UTC)
