Vroom goes the overly enthusiastic first timer

ChaosEngine says...

Man, I haven't been karting in years!

There used to be a twin-engined kart place near my parents house when I was in college. It was outdoors in Ireland which meant the track was wet roughly 110% of the time.

You could easily hit 100kph (60mph for the imperialists) on the back straight, turn the wheel.... and nothing would change! You would just aqua-plane right into a tyre wall..

good times

LOL, having flashbacks to the first time I tried a go-kart. I cut a corner too close and wound up wedging the front of the cart on a raised embankment. Since the back end was sticking out into the turn, they had to stop everyone on the course and come over to help me lift it off the embankment.

I was there on a date, by the way. Not my smoothest moment.

Are You Ready To Be Outpaced By Machines? Quantum Computing

moonsammy says...

I was hoping for more meat to his presentation, and was disappointed. I feel that he said absolutely nothing to help anyone in the audience understand what quantum computers actually DO or what sort of problems they'll help to solve. They'll absolutely not increase your FPS, as that's not what they're well-suited to do. What they are quite excellent at is taking a problem with many possible solutions and finding the correct (or best) one at an extremely high speed.

One example would be the Traveling Salesman problem. In brief, find the optimum route for traversing a number of points on a map. This is useful for things like scheduling package delivery routes, airline flights, etc. With a classic / current computer we write software that cleverly chugs through the possible solutions, throws out any that prove to be poor, and eventually gets to what appears to be the best or is at least a "good enough" solution. As the number of necessary points to be visited increases this problem scales in complexity quickly, so eventually a current computer would just choke on the problem and at best return an ok-ish solution in a reasonable period of time.

A quantum computer is a totally different beast. If it's "big" enough (IE, is comprised of a sufficient number of qubits), it takes the entire set of all possible solutions to the problem, and rather than iterate through them to find the best one, it checks them all simultaneously and immediately returns the optimum solution. It does this by using properties of quantum mechanics, and I think this is where the speaker was drawing his talk of parallel universes. If there are 3 qubits, they would exist as 000, 001, 010, 011, 100, 101, 110, and 111 simultaneously. The software would then define what the best answer would look like, and the computer returns the answer.

You can hopefully see how this totally breaks encryption. With a current computer and a long enough encryption key, an encoded message would take the fastest machines a huge number of years to decipher. With a quantum computer you hand it a gibberish encrypted message, it loads all possible transformations of that message simultaneously, and it then returns the transformation which looks most like a coherent message.

I'm excited to see what these machines can do for us, but they're going to necessitate some significant structural changes in how we handle sensitive data.

Japan tries to hide their breast mutilating, savage raping, mindless torturing of Chinese. In all honesty, if the Chinese government invaded, then murdered every politician and news venue that opposed teaching the true savagery of Japan's recent past, that would be 110% justified. In fact, it would be moral--since Japan is trying to sweep it under the rug in some morbid attempt to feel better.

What Happens To The Few Good Cops

newtboy says...

Yes, that's one of my problems with police, lax recruitment. They should do a better job screening applicants, far too many bullies make it through the process. The image they present only attracts the wrong kind of people, and even screens out better applicants (allegedly for anyone over 110 IQ for instance). The right kind of person wouldn't be accepted in the current cop culture (as this story illustrates clearly), and the right kind of people also wouldn't want to associate with them.

I think some officers do make that much on salary, but quite true it's not many. When you count the benefits they get though, they are not under paid in most cases. Most get free medical, life insurance, retirement, many other 'freebies', and incredible overtime, so looking at only base salary is not an honest assessment.
Where I live, $200000 is probably more than 5 times the average pay rate...in some areas it may be the average pay rate. In high cost of living areas, I agree, it would be right to pay them better, (but conversely, that means those in Detroit should be paid less for a more dangerous job...how to reconcile that?) but we should DEMAND better performance everywhere, with zero tolerance for abuse.

EDIT: It seems we could retrain ex-military for the job. They've proven they are willing to take MORE dangerous jobs for far less money ($20-30K last I heard). That's a possible win win, vets get a good job program, we get an improving police force...as long as the retraining and testing is thorough.

Then your problem is police recruitment.. pay cops $200k a year and you'll have an army of Jedi Knights. But we don't..
