how many talks are in Russian by the way?
xiangfu has joined #qi-hardware
<Jay7>
lekernel__: almost all :)
<Jay7>
this summer it was about 2-3 talks in English
<Jay7>
but I think you may easily ask someone to translate

hi
<pcercuei>
does x >>= 1 will eventually be 0 if x is < 0?
<pcercuei>
will x >>= 1 eventually*

<kyak>
are you in some code obfuscation contest? :)
<pcercuei>
no ;)
<wpwrak>
pcercuei: that depends on whether x is signed or unsigned. if it's unsigned, it will converge to 0. if it's signed, whether it converges to 0 or to -1 is implementation-defined
<pcercuei>
x is signed
<pcercuei>
ok, that's good to know

<larsc>
in C shouldn't >> always be a arithmetic shift?
<larsc>
ok, apparently it is compiler specific
<larsc>
but I think in practice all compilers do a arithmetic shift
<wpwrak>
larsc: and char is always unsigned :)
<pcercuei>
-fno-signed-char
<wpwrak>
or, the more modern variant: char is always signed
<wpwrak>
pcercuei: that's cheating :)

oh yeap the correlator is implemented on a spartan 6 + a smt32f4 that runs the libswiftnav
