holy crap, just find the right archive/list for what you seek (i really didnt have to dig that hard), and everything you read just works.

as for the "official" source, almost 2/3 of them are missing and in one case just incorrect.

and fragman i see what you did there

talk about embarrassing. i was stumped on this for years. until i realized my cipher went on the wrong track. test your algorithms!

i probably went a tad overboard, i wrote my own 'font maker' type program, you give it some text, start drawing the black pixels out, an option to scale it (in case i was slightly off, or in this case, unless the source image appears to be resized from the original font text size) then you can grab ...

heh i was stumped for a while until i remembered the original mentioned euler as a hint. fixed up the equation, and started plotting a black/white image for whose that satisfy it. the eps ^ (huge thing) is also hard to see from images generated by the equation... had to parse it manually to make sur...

HI guys im working on a poor core 2 duo that really needs to be replaced and given some of the challenges here i got something new to aim for then "ready for games for next few years" basically... im debating if i splurge for one of those 1000$ intel 6 core 12 thread processors, or just st...

md5 is less likly to have hash colisions but requires more memory (16 bytes vs 4) and since i use c# for most of my coding it has a built in library to just hash whatever byte[] array you give it. on the plus side crc32 can be compaired as a simple int and even sorted nativly, requires slightly more...

holy crap, i put in a solid month of man hours into the warmup solution (really only reason i solved it today was a very lucky guess) and saw this one.... impossible.... every letter is directly effected by 5-6 keys (26 - 27 bits, this doesnt count the other keys causing which key is picked)...might...

i was actually amazed at how many of the notes my sister could pick out by ear, turned out to be only 1 short(but a lot of the "answers" were maybys), theres no anagraming needed, no sharp/flat notes, the order low to high is the answer....but keep in mind, there is a (depending on the pro...

you need the full...answer... not the first copy you see...

holy @#$%# this is a tough one, managed to get mine down to 865 instructions, (curse that cycle limit) and i seriously have no idea how those insane people can get it to 97, too many symbols need to be stored which takes too many instructions to save which propagates through the functions needed to ...

wow, i was copying the text so i can start processing it for patterns or invalid words and i eventually come across that... landmine.. i was like #$%@ wasted 15 minutes.... heh.

i wrote a "bigfloat" library using a few bigints so i could take an accurate ln to (in my case) 40 places but it was SLOOOWWW hehe. i didnt optimize it at all so it was inherently transfering back and forth to strings and working in base 10 half the time. if i knew mathmatica had one built...

wow talk about annoyingly simple, it had me stumped for like a year. and ya everyone treat the 503 as 593 but you really dont "need" it

at first i tried just dumping all the pngs (since the html was obviously a single packet so you knew where to start and stop) but the background image was corrupt. assuming it was important (silly me) i then started writing my throw away program i wrote my own packet parser from scratch using wiresh...

heres a C# implimentation its for crossflip but its easy to modify for any of them, i obviously edited out stuff to make sure you get practice. i only provided necisary parts for the web interaction. technically i also changed the username password to be seperate strings im not entirly sure if it le...
