+22:56 < neauoire> how large do I make the dictionary?
+22:57 < cancel> yeah. and the dictionary is just the 
+                previous 256 bytes of the file. or, if you 
+                haven't progressed through 256 bytes yet, 
+                whatever you have
+22:57 < cancel> so if you're 20 bytes into the file, your 
+                dictionary is the 20 bytes you've already 
+                processed
+22:57 < cancel> if you're on the first byte of the file, 
+                your dictionary size is 0
+22:57 < cancel> if you're on byte 500, the dictionary size 
+                is 256
+
+22:58 < cancel> if your dictionary size is 0, you're 
+                definitely not gonna have a match
+22:58 < cancel> if you don't have a match, you need to 
+                emit the literal command
+
+22:58 < cancel> if your dictionary size is 0, you're 
+                definitely not gonna have a match
+22:58 < cancel> if you don't have a match, you need to 
+                emit the literal command
+22:58 < cancel> and then just slap some bytes down into 
+                the output
+22:58 < cancel> but... how many?
+22:59 < neauoire> it's designed to be stream right?
+22:59 < neauoire> mhmm maybe not
+22:59 < cancel> yeah, but you have to write the size of 
+                the literal first
+22:59 < cancel> so... how big should the literal be?
+22:59 < cancel> well, you don't know yet
+23:00 < cancel> so, just write that the literal is 1 byte 
+                long, and then put that first byte of the 
+                file you were looking at for a match
+23:01 < cancel> now, you're looking at the second byte of 
+                the file
+23:01 < cancel> repeat the process above
+23:01 < cancel> your dictionary is now size 1
+23:01 < cancel> and it has that first character in it
+23:01 < cancel> let's say your file is 'abcdefg'
+23:01 < neauoire> yeah
+23:01 < cancel> your dictionary is 'a'
+23:01 < cancel> and the next character is 'b'
+23:01 < cancel> well, there's no match in the dictionary.
+23:02 < cancel> so you need to write a literal again...
+23:02 < cancel> but the last thing you wrote was already a 
+                literal
+23:02 < cancel> so just combine it with the previous 
+                literal
+
+23:03 < cancel> ok
+23:03 < cancel> you can make a 'compressed' file that 
+                doesn't actually compress
+23:03 < cancel> it can just be all literals
+23:03 < neauoire> it'll take me a while to even just 
+                  accomplish this bit
+23:03 < cancel> it will be bigger than the original input
+23:03 < neauoire> ah yes
+23:03 < cancel> but it will still be a usable file for the 
+                decompressor
+23:03 < neauoire> let me try that
