It reduces mileage by more than it reduces emissions per gallon. But if it were really destroying modern engines left and right, we'd have heard about it, the same way we heard about ultra-low-sulfur diesel fuel destroying truck engines.
What you have described is exactly the Chinese government model. Except for the hiring part - the US clearly does that at Def Con, but instead of threatening to jail people they threaten to pay them 6 figures.
How soon we forget. The FBI arrested Dmitri Sklyarov at DefCon.
I shower and wear clean clothes and different jeans. If you held these up with any other pair I have, I doubt you'd notice a difference. They don't smell like laundry soap, but they don't smell like crap, either. Try it. You'll be surprised.
I've found that jeans get a funky musty odor after about a week, less if it's hot and humid. Not overpowering at least at first but if I pull them on after showering I definitely smell them -- then I get a fresh pair.
The government has created a martyr. If they prosecute him again it will rally his troops.
He has no troops. If they prosecute him again, it'll be buried in the back page of a paper no one reads, or maybe it'll make Slashdot. Nothing will stop them, and this time they'll win. Or if they don't, they'll do it again.
The only part of the DVD you can exclusively exploit as an owner is the shiny disc, just like the only part of a lithographed print you own is the canvas.
Not just the canvas, but the ink on it, arranged as it is. This has actually been important in copyright cases; there's one where someone was buying poster prints, physically transferring the ink to canvas, and re-selling the canvas print for a higher price. They won; this was not an infringement of copyright.
What has _already been proposed_ is that all cars won't start unless the driver proves they haven't been drinking. For some reason most drivers aren't any more happy with that proposal than gun owners are with this one.
The media is inseparable from the content. If you've bought the shiny disc, you've bought the copy of the audiovisual work embodied within it. There's no license necessary.
And copyright law does NOT operate on a blacklist system. There are specific rights granted to the copyright holder (which include reproduction, but not private performance, for example); they do not get "all rights except those excluded".
NYCs turnstile jumping crackdown is just a money grab. For instance, suppose you have an unlimited metrocard and the turnstile doesn't work; it accepts the card but doesn't open. There's no one nearby to help (the booth for the attendant is, as usual, unstaffed), and you can't use the metrocard again for some length of time (from 15-60 minutes depending on the station). So you hop the turnstile.... BAM two cops come out of the hidden room they've been watching the whole thing from, shove you against the wall, frisk you, and give you a $60 summons. Should you take it to court and tell the judge your story, the judge will say you're guilty anyway and you're still out the $60.
They can be bought, just not over the counter. Theft/robbery is never an inevitability or requirement just because somebody likes to do drugs.
If you buy oxycodone on the street, where do you think the people you buy them from got them? Maybe they got them with a fake prescription or some other merely fraudulent means, but most likely they stole them.
Yeah, meanwhile I'm sitting here on a bunch of broken bones, carefully rationing my painkillers because if I ask for more I'll be put on the DEA drug-seekers list and be dispensed nothing stronger than acetaminophen for the rest of my life. (NSAIDs are contraindicated for broken bones, BTW
Drug laws suck. Still doesn't mean armed robbers ought to be excused, particularly armed robbers dumb enough to pull a gun on the cops.
OK, now we've decided that and decided not to fight any more wars. Oops, we're now being run by a repressive dictatorship without the same moral hangups. Life sucks.
RSA does not rely on discrete log. It rather relies on discrete root.
RSA private key is p,q,d where p and q are large primes and d is the private exponent. RSA public key is n, e where n = pq and e is the public exponent. The private exponent d was chosen such that (m^e)^d (mod n) = m for any m (message) 0 m n.
RSA encryption is c = m^e (mod n) RSA decryption is m = c^d (mod n)
Suppose I have an RSA public key n, e. I pick an arbitrary m and calculate c = m ^ e (mod n)
Now I need to find d such that m = c ^ d (mod n) This is the discrete logarithm problem.
Being able to solve discrete root would ALSO break RSA; if you could figure out the eth root of c (mod n), you could get the message without having the private key.
And for completeness, solving integer factorization breaks RSA because with p and q you can calculate d.
Elliptic curve encryption also relies on a discrete logarithm problem being hard, but it's a discrete logarithm over an elliptic curve, which is believed to be harder.
Breaking the discrete logarithm problem breaks both DH and RSA; obtaining the private exponent from the RSA public key can be done by solving the discrete logarithm problem. However, this algorithm solves the discrete logarithm problem only for certain fields (Galois fields of small characteristic), and I don't believe those are the ones interesting for RSA or DH. (RSA uses a composite group; DH uses a prime field of large characteristic)
Even better would be the 20 year veteran who can take those fresh out of school enthusiastic newbies and get high quality software out of them on a predictable schedule
The article contains the same flaw that people who rabidly declare unit tests as a panacea. The article basically shows that after discovery of a bug, a unit test can retroactively be constructed that would have caught the bug, therefore it's inexcusable that the bug got released, ignoring the fact that is hindsight.
The function was supposed to check various ways a key exchange message could be screwed up. The minimum set of unit tests appropriate for such a function are pretty clear -- feed it messages that are screwed up in each different way, and make sure all of them fail. And feed it a message that is not screwed up and make sure it succeeds. This won't catch everything, but it would have caught this one.
There are lots of times it's unreasonable to expect a developer to have written a unit test which would have caught the bug; this isn't one of them.

Since the NSA isn't allowed to do that, chances are the UK (GCHQ) DOES do it, and then shares the take with the NSA.
...because it looks like regulation is working overtime to stifle development of autonomous cars before they become practical.
Not to worry, come winter.... OH SHIT THAT DOESN'T WORK WITH MAMMOTHS!

Yeah, GP confused Ritalin with Adderall.
