"I understand we Remove O’s from message to ensure that the original information can be passed to use"
For instance, I do NOT understand that.

Maybe i'm wrong, do you have any ideas of a definition of bit stripping that would clear it up.

CPallini 10-Dec-13 8:25am

Probably I am wrong too. However, I suppose, it is removing 'unnecessary bits'. For instance, if you have ASCII characters encoded in bytes, then the most significative bit is always 0 hence you could strip it off without loosing the original message content.

Who need this kind of "bit stripping" ever. Where did you get this term? Any links?
The situation is pathological in first place. How did you end up having those strings with binary records? This "data type" is utterly inefficient and simply should not be used. If you need binary operations, work in binary object not string.

Generally, the trend to work with strings representing data instead of data itself is some trend of these days, a real course of many beginners.

And, after all, what's the problem? Manipulation with strings? (But better don't. Would you do something useful instead.)

I used to work with a hardware engineer who came up with a new compressions technique: throw away all the zero bits "because they mean nothing". The compression ration was significant, but he never did get the decompression routine working (quelle surprise)

He became even more enthusiastic when we suggested a second pass with all bits inverted... :EvilGrinSimiley:

I know that guy: he is my PM, now.

When I was just starting in this game, I figured that the ultimate compression technique would be to find a random number seed and offset which caused the standard Quick-C random number generator to re-generate the whole file. When it worked, all you would need to send was two 16-bit integers, and your whole file (regardless of how large it was) could be regenerated.

After some careful but extensive testing, I realised that compressing the data in the first place might take some considerable time...and dropped the project.
