i've never heard of this but this doesn't sound all that unique when you think of it.
The picture of the lava is just a key. if he used it as a one-time-pad or the middle 256 bits as a Blowfish key, it's just as secure as any other key. The lava lamp is a "random" number generator.
in fact, i'd question its security if it's a one-time pad. there's probably a lot of regularity to be seen from one picture to the next.
i found this and it's a little bit more detailed. What I want to know now is how much some of this stuff will cost and how do we sort out which little bubbles are O2 and H. wouldn't the whole thing just start fizzing like an alka-seltzer when you drop it in?
does this mean that you put a plate of this materal into a tub of water and it will produce hydrogen as long as there is water?
or is it the less attractive option: you put a plate of the materal in water and when it dissolves or doesn't produce any more hydrogen, you need to replace it.
Not to be dismissive about this but who cares if we don't understand about the Kuiper-belt for the next 150 years? Can you give me any good reason why this information would advance technology or science more now as opposed to 2200? Besides, I'm willing to bet that in under 150 years, we'll be able to get a ton of information from Earth/orbital/Lunar based observatories without waving to throw a $2bn lump of metal out there.
As for NASA making less exotic endevors cheaper, hey, I'm all for that. If we can save some money on the monthly missions, that's all the faster that we'll be terraforming the Moon, Mars and the Jovian Moons (except for Europa of course).
I've been disappointed in NASA's apparent lack of direction with regards to space settlement. Sure the space station is a nice step and yes, I'm aware that we've been to the Moon and we've sent expensive trinkets to Mars but we still don't have a foothold off of this mudball and it doesn't look like we'll be going in that direction any time soon.
I'm a nerd, no doubt about that. I like space and science as much as the next guy but I'm also cheep. My question is this: Why spend our money on a Pluto probe when we could put it towards getting ourselves to Mars or the Moon?
Has anyone thought of this from a cost/return perspective?
I'm not a physicist or anything but doesn't faster than light communication allow for information to be sent backwards in time?
Also, will this allow me in any way to go to my parents' home town and get into a chance with the local bully, resulting with a dump truck of manure being dumped on him?
Growing up in the city, I took the bus and train and remember almost every flat surface (and a lot of the rounded ones) were covered with graffiti. Does this system take any consideration for that type of thing?
Also, what about the homeless hijacking these for homes, junkies doing their thing, robberies taking place all while there's no one to alert the authorities.
I know everyone's security happy these days but if this is going to be important if this is implemented in a big city.
First off, diff doesn't work if the kids are smart enough to change their variable names and add spaces here and there.
I was a grader for the C++ and data structures class back when i was in school. And I saw my share of cheating. One instance that stands out is when a bunch of kids had variables called "dude" and "funtime". Problem was, they had enough differences elsewhere in their code, that an automated diff wouldn't have worked. For a while, I was going to write some fancy perl that would look for certain cheating patterns that I was seeing, but then I got lazy.
One deeper way to check for cheating is to pass code through the front end of a compiler and check what comes out. if there are too many simmilarities, they will stand out even if kids change paramater names and the like.
Finaly consider this: Checking for cheaters in a class isn't just doing a diff of two files. For every student in the class, you have to check his code against everyone else's. This is a O(n^2)problem. My class had around 350 people in it
so that's 122500 checks to do. If it is anything more complex than a diff (multiple files, compiler front-end, fancy perl parcing) this can take a mad amount of computing.
Of course not. Just because our taxes pay for something that the government makes, that doesn't mean that it should be posted for all to see. Take for example code that the NSA writes. I would consider it a matter of national security that this would -not- be available for nationals and non-nationals to examine our latest code crackers and know how to avoid our strengths and exploit our weaknesses.
I actually am a product of the Chicago Public School system and while I'm appalled at this proposal, I'm not surprised. I went to one of the best public high schools in the city but there were guns found on a monthly basis, metal detectors, gang members, security guard/student relationships, and I sat next to a kid in driver's-ed who had a 0.0 GPA. How I got to where I am today is a wonder.
Anyway, King Richie has consistently ignored the state of the school system in favor of putting plastic covers on rotting infrastructure and projects like the ridiculous Millennium Park. This is just another example of Dailey junior throwing money to his mobbed up pals on projects that should never have started.
I don't know what the thing was called, but I met a blind user back at school who had a 70 character wide brail device that popped up pins to tell him what was on the current command line or line of code. What made him so hard-core was that he hd to memorize a whole program line by line without the quick reference that glancing up and down in a window affords most of us. Has anyone else seen this kind of device or know what it is called?
I have no expertise in the area aside from movies and specials on the learning channel, but did the collapse of the buildings look like the structure giving way due to the plane crash or a planed implosion? Any demo experts out there with observations?

i thought that if a language supports object oriented programming, then it is a OO language.

May you make each other happy to the end of your days.
They will not do this because:
1) 5 minutes after it's released, it'll be warezed. Total profit $100
2) You can't sell a special leather-bound edition of a text file or a collecters edition set of 7 books with one 4 on paper and 5 on floppy.
Follow the money, everyone else does.
This article probably covers a lot of questions that may come up for you.

If you don't have that much of experience, I would start making a device driver for a relatively simple device.
dude, don't take the bait! he's just trying to get someone to write a driver for his mp3 player.

Goddamnit! This is the second time I've posted a story, had it rejected and seen it posted by someone else within an hour.
Shit.
