Limbo

Hi everyone In one of my lectures at the university I just learned about the MPI (Message Passing Interface) in C++. But sadly we didn't get an example of a problem which benefit from parallelize it and using MPI. As far as I understand this topic, for this to work the problem should be medium grained, but I can only think of fine grained or coarse grained problems, which won't benefit from using MPI. Do you know some problems which greatly benefit from MPI? Greetings Limbo

I would advice you to start witht RC4. It's still used, like in WEP, and best of all Wiki comes with pseudocode ;-) http://en.wikipedia.org/wiki/RC4 It's nearly VB-Code. If that doesn't help you post again I think somewhere in an old backup I still have my implementation of RC4, DES, TripleDES and IDEA from back when I was in school and used to code in Visual Basic 6.0. But I think with the pseudo code from Wiki you will succeed.

I thinks there are so many great cryptographers from all over the world. Brilliant minds like Adi Shamir, Ronald Rivest, Leonard Adleman, Bruce Schneier, Ross Anderson, Eli Biham, Don Coppersmith, Hideki Imai and so on. I think if there is a backdoor someone would have found it and made it public. I simply can't imagine that people of any goverment are smart enought to outsmart all these brilliant minds.

I really like to use quotes from The Simpsons, Futurama, How I met your mother and expecially from The Big Bang Theory, but people never catch my quotes. Only one friend of mine gets them. And sometimes we're loughing really hard about some Simpsons jokes, but nobody else gets the joke and they're just looking at us with those big eyes :) . I think that's how I naturally show that I'm a nerd, and I'm proude of. Or the times when someone is discussing something about physics, or computers, or CERN, or WiFi, and I'm realising they have no clue what they're talking about, so I help out and join the discussion with something like "Acctually the MAC is only 48Bit and not 256Bit. You're thinking about your WEP Key or probably about your IP.... do you use DHCP?... and it's DNS not DMS... do you have a Router or a Switch? - I own a what what???... Do I have to use WPA?... The thing you sayed with the thing where you put numers in, that's a what again?... Where can I download WEP?" And I'm realising, man, I'm going a million miles an houre for them, oops. That's when I realise I'm a totally nerd. But since 3 weeks ago I have my best eyecatcher ever and so finally everyone gets to know I'm a nerd. It's my book "Quantum Computation and Quantum Information" by Nielsen and Chuang, which is a really good book. I love to see people turning their heads upsidedown just to read the title and then stare at me, and look me over, like they can't belive someone is really reading that stuff. Sometimes they try to read in my book and if they can, they read a few lines and then they begin to smile and shake their heads. And I can see them seacretly pointing at my book so theire friends would also read my title. That's soooo funny. I love those moments. I while ago I thought about wrapping a Harry Potter cover around my book, because some guys called me a show-of, but then I thought why to hide, just because I'm a little nerdy and some fags think I'm a show-of, who cares about what other people think. Now those moments when people stare at my book, that's when I'm most proud of being a nerd! OT, but funny story: Once a women red the title and then tryed to read in my book, she sat vis-à-vis in the train. But she always checked if I was looking at her. So I gave her a better look into the book and I could see her starting to read and she totally forgot about to check if I noticed her reading. So I looked her right in the eyes and begun to smile :D and suddenly she looked up in my face and as she saw me smiling she flushed, I've never seen a women getting such a read face, she must have been so embarrassed :-) Then I asked her if she was a physicist, but she wasn't. So I asked her if she was interested in quantumphysics, but she replied "I'm not in to those smart guys things". :D :D

I was really afraid what could happen to all the nuclear powerplant if people abruptely stop consuming energy, but the nuclear fuel rods were still pulled out to the max. So clever as one can be, I helped compensate the energy fluctuations and consumed as much juce as I can. I heated up my baking oven, turned on my coffeemachine, made some toast, microwaved popcorn, set every hot plate to maximum and turned the washingmachine and the drier on. But I turned off my 11W energy saving light bulb and lighted up 10 candles (btw wich produce about 80W each) so nobody in my neighbourhood can see light in my apartment and so they can't blame me destroying the enviroment. :)

The problem about your exercise is that if we don't know what we are looking for in your file, we won't recognize the solution when we see it. That's the old story about the answer 42. If you don't expect an answer you won't be abel to tell if it is the answer. (hard stuff, I hope someone understands) I could just say: I found the solution, the key is 0 and the file contains a series of random numbers. Or if I decrypt it with the key "love" I get a series of ones and zeros, where the bits are the result on measunging a decay of some radioactive material and whenever a nucleus decays there's a 1 otherwise a 0. You know what I mean? If we're not looking for something specific we would find everything and nothing... But if I'm searching for a English text in your data, then I can look out for some letters, vocals, consonants, and statistics of them.

It really depends on what you like. If you like to create a window with buttons, drawings, textboxes, tables, ... you might want to start with Visual Basic or better, with C# If you think windows aren't that important, but you like to stress your CPU as much as you can, perhappes C++ would be great for you. If you love colors and shapes jumping around, interacting with you, try out flash. If you like to optimise just one process that you will do millions and millions of times as fast as possibel, you might get happy with C and digg in to Assembler, but that's the hardcore nasty dirty stuff that nobody really likes. If you like to just messing around, having some intellectual fun with yourselfe, try out a esoteric language, like BrainFuck. Visaul Basic, C#, C++, C are very similar. If you know one, you won't have problem understanding the others, and with 1 week training you will learn them. They're like French, Italian, Spanish, Portuguese, Latin. If you know two of them, you know them all.

I can even solve several Rubik's Cubes with diffrent sizes. Even the big ones, the V-Cubes. My timings are about: 2x2x2 (also named mini cube): 40sec 3x3x3 (original Rubik's cube): 1min 4x4x4 (Rubik's Revenge): 9min 5x5x5 (Professor Cube): 25min 6x6x6 (V-Cube 6): 59min 7x7x7 (V-Cube 7): 5hrs I've just started to solve big cubes. I played a lot with the 3x3 cube, but I only solved the 4x4 about 10 times, the 5x5 about 5 times, the 6x6 2 times and the 7x7 cube just once for now. BTW: I just solve cubes for fun, while my PC is calculating something on every Core and I have to wait :-)

Hi everyone We're about 15 people downloading the "Completed Rainbow Tables" made by the Hak5 community. And about 10 people over 50%. But we're stuck at 92.2%, since several month. Could please someone seed the rest of this torrent? I'm shure someone still got the missing files. I'm willing to keep on seeding for a long time after completing. Thanks a lot in advance.

It's not quite finished. I'm still waiting for some LEDs to be delivered. But that's what I got so far: My paintjob. Drawn with brush and acrylic and a calm hand. That's my selfmade CPU-cooler. (made in Switzerland) The Relais that starts and stops my pump as soon the PC get's turned on or off. I show you more pics as soon as the casemod is completed.
