The radiation produced is microwave radiation, at 2.4GHz.
The power is significantly lower than that of mobile phones, and nowhere near the power leaked from the average microwave oven.
Not only is the signal weaker, but the transmitter is usually not located right next to our brains (as is the case with mobile phones). Therefore the safety issues to the best of my understanding are nonexistant.
The article mentions the pioneer contains a plaque designed as a greeting for other civilizations.
If an object like pioneer 10 was to come close to our planet, would we even know about it? Or would it just fall and burn in our atmosphere, receiving as much attention as the averge small meteor?
"22 hours later, from 79.4 AU, DSS 63 acquired the downlink on time at -183 dbm. After peaking the signal to -178.5 dbm, they locked the telemetry at 16 bps with SNR of -0.5 db."
Sounds JUST like my 56k modem:D
Holy S**t - 2.4GHz dangerous?

Well, if wi-fi is supposed to be a problem, imagine what happens when we, dare I say it, use mobile phones. Or what about using microwaves to cook our dinner.
Microwaves and cellphones use the same frequency and give off many times more microwave energy. Are they now going to requlate our cooking habbits? Cause only terrorists use microwaves?

No, not at all. If you followed the thread through you would see that it was in response to a question about weather or not DVDs can be copied without decryption.
Of course CSS turned out to be useless, but that was thanks to DeCSS. I find it higly amusing how the movie industry hires the best subcontractors who claim to have developed an 'unbreakable' technology. They threw millions at securing DVD. And all it took was one person skilled and knowledeble enough to outwitt them.
As far as I know it isnt that easy. CSS is actually cleverer than you think.
From what I understand, CSS makes use of codes embedded in a factory-written part of the DVD media. Standard DVD burner and media combinations do not support this marking of a disk as CSS-scrambled. Of course making a perfect replica of a DVD would mean that decrypting it isnt neccessary, but standard DVD-writers just don't support this.
If you want to create your own encrypted DVDs, you can buy special [more expensive] 'Authoring' media, (as opposed to the 'General Purpose' DVD-R media which is the consumer standard). AFAIK though, the data written to the disk must be encrypted with keys matching those embedded on the fabricated part of the disk.
Its frequently been said that the present limitations can be overcome by moving away from silicon.
Silicon based CPUs have evolved and been perfected over the years. If companies decided to create proccessors based on alternate technologies, what are the chances of jumping straight in where present CPUs left off from?
Its very likely that it will be many years until the technology matures enough to compete with existing proccessors, and then, only then, will it be able to go beyond the speed limitations.
But during the development phase, there is no source of income to fuel investments and keep development going... Customers are not going to buy 500Mhz proccessors. I doubt that moving to an alternate techonlogy will allow jumping straight into the production of 3Ghz CPUs. And with no income, there is no development.
No. They should say they are distributed pseudo-randomly.
The distribution is NOT normal. The normal distribution states that the mean digit will have the highest probability of occuring, and the further away from the mean you go the lower the probability. This contradicts your next statment.
"that every digit has an equal probability."
This would define a rectangular distribution, and whereas correct, is not the same as saying they occur randomly. "123456789123456789..." has the same probability of each digit occuring, but is hardly random.
I agree with the principal behind that, but you and I both know it's not that easy.
For doing development work for myself, learning new concepts, hosting servers, linux beats MS for me hands down.
But when it's a case of collaborating with hundreds of other people who all work on microsoft's products, it would be proffessional sucide for me to not accomodate them and refuse to exchange files until they switch to linux - it isnt going to happen.
Fundamentally I believe the world would be a better place if linux was more mainstream than windows - but it isnt, and changing that without only harming yourself isnt that easy. The only way is to use linux wherever possible. If you need windows, run vmware in linux, try wine, whatever. But emulation isnt perfect, again in the long run all I acheive is a pain in the ass, and not uses switching to linux.
A move like this will be the direct equivelant to proffesional suicide.
I love all of linux's advantages, but I do not use it as my main operating system. This isnt out of choice. My main problem is that people I work with use M$ proprietry software, and although there are linux equivelants, they are not 100% compatible. Getting closer, but still not there.
If microsoft were to release client side software for linux, that would no longer be a barrier. People could move to linux, and still use the same software until they stumble accross a better alternative.
Same applies to server side. It would enable users to switch to linux retaining the apps they need - until they realise that there are alternatives which will work better...
I find it funny how an independant company tries to predict what microsoft will do, and come out with a prediction as absurd as this.
Wait, what next, a MS linux distro... old but relevant www.mslinux.org
Kewl, backend stuff huh... so we have IIS for linux? No wonder it'll take a few years to port the code... I mean all those directory transversal vulnerabillity codes rely mainly on WinAPI.

A while back I was attempting to brute force the MD5 hash of a forgotten password, and when I read the slashdot story about this database, an idea occured to me.
Currently on a fast PC, it takes approximatly 400 days to test an MD5 hash for collisions with strings up to 8 days in length, and using the charset a-z,A-Z,0-9.
What is these were precomputed and stored in an indexed, searchable database. It would take a while to compile such a DB, but with the aid of parallell proccessing, or perhaps a distributed broject similar to SETI@home the time could be reduced.
If this was created, people could just enter an MD5 hash, and in a fraction of a second get back a list of known collisions. Makes you want to rethink MD5 passwords for security.
Has something like this been attempted before? Is something like this even possible (I imagine storage space could be forbidding)?
It's a novel concept, but I see limited future for it. Most worthwhile conversations originate spontaneously.
It is just not possible to have a computer choose for you who you want to talk with. If it misjudges, false alarms will cause clumsy and/or embarrasing situations.
What if you just dont feel like talking and forget to turn it off? Or perhaps it suggests a perfect personallity match, but when you look at the selected person you want to throw up?
Imagine the most likely common scenario that you walk past someone, your device goes off, their device goes off, but for whatever reason you just arent interested to make conversation. Itll be clumsy just ignoring it, or making up excuses.
And even when both sides are willing just to meet random people and talk. It's clumsy and hardly romantic trying to initiate a conversation "hey babe, my beeper just went off, turns out we have a lot in common, wanna f*ck?"
The only use for personal ad-hoc networking technology is in exams;)
Saying that, widespread use of WLAN devices carried around your person would have one major use - if it supported routing and dynamic route calculation. It could become a free wireless internet. If you wanted to call someone accross the other end of the town, imagine the decice finding a route from person to person, to whomever you are calling... or to the nearest internet gateway...
Well, yes, I agree with that. The whole thing is just a waste of time.
Well, perhaps in engineering, where it is often critical to make very exact calculations, slightly more accurate approximations than 3.14 or 22/7 need to be used.
I was just making the point, that its not a case of wanting to express something as a decimal rather than a fraction. As it cant be expressed as a fraction either if your being exact.
Windows calculator gives me "3.1415926535897932384626433832795", and noone will ever have a legitimate use for more decimal places - simply because they will be dealing with measurments that will never be that exactly done in the first place.
Yes and no...
Pi and e are not just random numbers found under a rock;)
The current formulas used for them were devised by human beings, and not written in the skies by god.
Not to mention that an irrational number will have every sequence you want, repeated an infinite number of times, somewhere along the line.
Ummmm NO...
22/7 is used as an APPROXIMATION for pi sometimes. And not an accurate one at that.
22/7 = 3.1428...
Incorrect after the 3.14.
The number is IRRATIONAL.. it cannot be expressed as a decimal nor fraction, and does not reccur.
