Comment RBF (Score 1) 48

As far as I know the state of the art for nonlinear optimization when the objective is a very expensive process to run (or simulation of a process) is Radial Basis Function modeling/estimation. Much of the work on this was done at Cornell University - see for example Rommel Regis's papers. These algorithms do some random sampling, then build a model of the objective function, then based on that pick one or more new points to sample, and repeat.

Some of the ones I've read, it does sound like he is handing someone's head to them, but he's usually also explaining what they did that was wrong, and why it was wrong. So IMHO that mitigates some of the unpleasantness. He does seem to want the recipient to learn from the experience and not do whatever it was again.

Well, unlike Nokia they are in more than one line of business. But they have been executing poorly for some years and have a history of doing dumb acquisitions, culminating in the disastrous Autonomy deal in 2011. Ray Ozzie can't by himself fix any of that. But arguably he can't be worse than the slate of directors who got them to where they are.

I think that is true, but there is not any fundamental reason why something that is technologically possible can't be prohibited by law. Nor any reason governments can't be made subject to the law. In the U.S., Nixon was about to be impeached over misuse of federal resources to attack and embarrass his personal enemies.

By and large they don't make expensive gear. And as far as I can tell it isn't much worse than the other mass-market stuff it competes against. Their poor reputation among audio buffs is somewhat deserved but IMO mainly because it is cheapo gear and there is some tradeoff of cost and performance, certainly at the part of the cost curve they are operating in.

True enough, but you do not want to have the issue where the first sign of your success is your website failing. Early users get turned off if the service is flaky. So you can't just throw up a free website and wait to see when and where it crashes. A little planning is always good and so is a good reasonable starting architecture. That would include for example designing from the start for running with multiple backend servers behind a load balancer.

Despite the current year tax increases, we have very low marginal tax rates on high income earners, compared to the rest of the world and compared to historic rates in the US over the past 50 years. High taxes are not the biggest economic problem most people face. Ask someone who is unemployed whether high taxes are a problem for them.

in electronics. When I was a teenage geek, a ham up the street gifted me with a number of things including a marvelous "boat anchor" surplus shortwave set. And lent me a number of other things like a working scope. It was a great learning experience. If something wasn't working or couldn't be made to work, I salvaged components from it. My parents had no idea I was debugging 400 volt tube circuits. Somehow I survived.

Comment Anybody who sends a password in plaintext (Score 1) 250

in response to a reset request is not hashing passwords and would fail a security audit (but I have certainly seen sites like this). There is no reason for the remote site you are logging into to ever store your password, vs. storing a hash (a strong hash, repeated multiple times to make brute force reverse hashing difficult).

Computers can figure out all kinds of problems, except the things in the world that just don't add up.
