Who stole my RAM?

(depending on if the system supports 16GB sticks, which I doubt)
What?!
So I can only get 16G?
That sucks.

@xaade
based on the information that has been thus far provided, I have no idea how much RAM your system can support :P

@accalia I bet I could make a better compression algorithm than that.
Step 1: if the source to be compresses is the 1995 CIA world fact book in text format, compress to a 1 byte file that's not a valid WinRK file
Step 2: if it's not the 1995 CIA world fact book in text format then use WinRK.There. At least as good in every situation as the winner, and far better in the test in question. What do I win?
BARF is a compression algorithm that does something kind of like that, but it can compress files to 0 bytes!

@accalia I sit corrected.

Compression might up that somewhat, but not by a factor of six!
orly?
Assuming english text a good compressor can easily achieve 80+% compression ratios, this is of course because english text is highly predictable.
i found someone who tested over two hundred lossless compression utilities against a standard english text corpus (actually the 1995 CIA world fact book in text format) with an initial filesyxe of just under three million bytes. You can see the full list here but below is five of the better known compression utilities (along with the number one winner) and how they performed
Utility Compression ratio Result Bits per Source Byte WinRK 3.1.2 88.94% 0.8849 WINZIP 14 85.21% 1.1829 WinRAR 4.1b3 85.16% 1.1875 BZIP 0.21 80.84% 1.5331 GZIP 1.3.5 71.13% 2.3100
now a 6x compression ratio is 1.666666 bits per byte, which means that only GZIP (of the ones i chose to list here) fails to achieve that ratio. in fact the "worst" lossless compressor that succeeds at achieving a 6x or better compression ratio is
WinACE 2.69
which came in 128th place.so there! :-P
Wow! So much for the Linux folks' oft-repeated claim that TGZ is a better archive format than ZIP because it has superior compression...

hmm..... there's a point........
hold on. let's test something!
/me wanders off to find a larger corpus to test against.

@accalia Try 10 MB of data generated as the output of an RNG.

i was planning on testing against random data too.

Compression might up that somewhat, but not by a factor of sex!

@Tsaukpaetra No, that's the unperverted vixen.
