loops were suddenly discovered to be heisenbug
11:06

and all loops break
11:06
<@auREAX>
it could happen any time
11:07
<@auREAX>
this is why I use -funroll-all-loops
11:10
<@Azash>
Oh wait, it's -f unroll
11:10
<@Azash>
For no understandable reason whatsoever I always parsed it as "fun roll"
11:10

uh
11:10
< Syk>
isnt it -funroll?

Yeah but I mean the intention behind it

oh yeah

-O5 just replaces the most heavily-used parts of your code with NOP; best performance increase ever! Fewer bugs, too.

hmm... i think i'll go with a Arduino Mega for the time... the Uno is nice and cheap for for my PE Embedded project it doesn't have the pincount i need D:

gnolam: i'm going to do Project Euler Embedded, which basically at the moment involves using a 20x4 Character LCD as a menu and general display, a 4 digit 7 segment display to show how long it takes, and menu nav buttons
16:19
< gnolam>
Ah. 7-segment displays.
16:20
< iospace>
also an SD card that contains the best time, the current version of the algorithm for the problem, other things :P
16:20
< iospace>
so a lot of pins ^^;;
16:21
< gnolam>
Well. The LCD shouldn't take more than 8 or 9. SD cards... 4? IIRC. But if you want to drive 7-segment displays directly - bozhe moi!
16:21
< iospace>
oh yes
16:22
< iospace>
gnolam: SD card is a 4 wire
16:22
< iospace>
SPI interface
16:22

i /could/ use i2c but where's the fun in that? :D
16:23

(i2c for the LCD and 7-seg)

i'm sure those exist
16:29
< iospace>
yeah and? It's good for developing ahead of time (I've used somethign similar), but it's hard to verify that a 7-seg is being properly used without the hardware :P

According to the benchmark, it takes longer to perform the DCT in hardware than in software.
17:25
< iospace>
DCT?
17:26

Discrete Cosine Transform.
17:26

ah

The underlying magic of JPEG.

(JPEG in a nutshell: convert into YCrCb, downsample the Cr and Cb channels (optional), split into 8x8 pixel blocks, DCT, quantize, RLE in a zig-zag pattern, Huffman encode)
