Hi Joshy, just come across this and there's something I'm wanting to try. There's someone called Johnny Lee on youtube with a video on headtracking using the wii camera and remote, if you've not seen it then check it out to see what im talking about. I'm wanting to try something similar, I have a US...

Why does it feel like I'm doing someone's homework? #define encode(t,d,m,o) t=t*m+(d-o) #define decode(s,t,m,o) print s;(t mod m)+o:t\=m function encode_time_and_date(byval _year as ulong,_ byval _month as ulong,_ byval _day as ulong,_ byval _hour as ulong,_ byval _minute as ulong,_ byval _second as...

@albert MERRY CHRISTMAS!

I'm away for a few days, no PC, only tablet, will there ever be any chance of FB on arm Android?

No, not a bug, it's rounding to nearest but in the case of x.5 the nearest is neither round up or down so it rounds to even. It's possible to change the FPU rounding mode on x86 but I'm not sure if FB on x64 makes use of the FPU or SSE units for floating point ops, I'll have a look to see what's goi...

@albert I think we must have quite large drawing boards.

@albert An idea I just tried, taking say 7 bits at a time and counting the number of set bits, direct each 7 bits to one of 2 streams, one stream with mostly 0s and the other with mostly 1s, then compress each stream separately, so the stream with mostly 0s is compressed using 00=0, 1=1 and 01=2, st...

@albert I posted code to do that a page or two back. Change the '4' in the main sub to value from 1 to 4 to get permutations containing 1 to 4 different digits. function make_map(byval b as ulong)as ulong return (1 shl(b and 3))or(1 shl((b shr 2)and 3))or(1 shl((b shr 4)and 3))or(1 shl((b shr 6)and ...

But was he able to bring all the sheep back?

@albert, looks like you've got 0x and x0 giving out the same code.

@albert
Sorry, I thought you meant permutations of the sequence containing the digits 1,2,3 and 4

28 combinations is 4.8 bits.

Just some thoughts, i don't know much about it but maybe more randomish memory addressing when you're accessing the array would push the cache more, then there's also the SSE units that you might not be touching with that code, depends if the compiler uses the FPU or SSE instructions, but even if it...

@Albert Try changing the '4' in the main sub to a value from 1 to 4 and see what the output is too. function make_map(byval b as ulong)as ulong return (1 shl(b and 3))or(1 shl((b shr 2)and 3))or(1 shl((b shr 4)and 3))or(1 shl((b shr 6)and 3)) end function function count_set_bits(byval b as ulong)as ...

@albert

Might a string pointer be a pointer pointer?

Dim as ubyte ptr ptr p=cast(....

ubyte_=**p

Or something like that?

Accessing other bytes might need something like

ubyte_=*(*p)[n]
Or something like that, i dunno, at work just now and can't look into it.
