Typo:
worked on a continuation based microthread engine for python (precursor for a python tcp/ip implementation)
installed solaris and started exploring

solaris x86 syscall conventions seem to be: use a lcall $7,$0 instead of int $0x80, push all the arguments on the
stack instead of linux's speedcall convention that uses registers. also the lcall contains nul bytes, so we
need to create some 'lcall;ret' functionlet somewhere in memory before being able to use syscalls.
i think all this is sysv/386 default.

Maximillian: workend on makeing ScaPy work on MacOS X and SSL Fingerprinting.

Emin:

I have made some experiments with Java race conditions. Here is a nice article about this issue. I came accross also with a tool namely Ladybug which detects dynamically java race conditions.
