Change your settings where you subscribed.

Missing the point that async would have drastic improvements on
anything network base, even if you increase it to say 500 threads a
async model still pawns anything using threads for simple
connect/disconnect handling.

No, there wasn't. It was 12 lines of code which just called another
OCR library. (could be why you deleted the public repo this morning)

I did hear google cache does a good job of uncovering "OMG RAGE DELETE"

http://webcache.googleusercontent.com/search?q=cache%3Ahttps%3A%2F%2Fgithub.com%2Flfamorim%2Frebreaker&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a

I do have to declare myself the defaulted winner of this engagement
now because if you have to delete stuff in order to claim facts about
it...

I read the code could be why.

Totally because a bindshell trojan that connects to a port is
something highly special that the world will end if someone got a hold
of such a dangerous piece of code. In fact, why isn't the world ended
yet when you can just google and get a few dozen of them?

Should I tell you how "dangerous" and what "planet" do you live on to
release your so so very dangerous innovative python code? (hypocrisy
for the win!)

Curl is indeed great I agree. The rest I don't see as even a point
going anywhere?
