Comment Re:So it is not an accurate Documentary Film? (Score 1) 289

>Just to clarify, I believe Kip Thorne is the physicist who was a consultant on Interstellar, who made efforts to make the move more scientifically accurate than what Nolan could do on his own

And failed utterly. There are so many horribly bad manglings of physics in the movie that he's trying to salvage himself by saying on just one of the two dozen serious errors it's maybe sorta possible that it could be that way.

He should be ashamed of himself for granting the movie his imprimatur.

This is exactly right! Why do I never have mod points when I need them . . .

I have long felt this way too. As others have pointed out, the US is all about capitalism, so take away some of the shareholder dividends by making the power company rebate money paid for service when the service fails and the problem will solve itself in an efficient manner. Gradually increase the penalties on a fixed schedule so the companies can plan for long term upgrades where the infrastructure is at the highest risk (rather than where the the PUC officials live - which is, I suspect, a large part of the equation now). Mandating improvements on a monopoly only results in government fines that the company officials use in the cost benefit analysis about infrastructure improvements. Give the money back to the customer and that will reduce the "sting" of a power failure.

Imagine if you got 1 day of free electric service for every hour of downtime? I'd be very happy with that and easily convinced that the power company was doing their very best to restore service quickly because it was hitting them squarely in the pocketbook.

>China's producing 7.2 tons per person. The US is producing 16.5 tons per person.

Per capita comparisons are ridiculous since a large chunk of China is still non-industrialized. There's a reason why China and India always focus on per-capita numbers - by having lots of poor people living in non-developed areas, they can get lots of extra quota for their highly polluting power plants and factories.

A better comparison is CO2 emitted per kWh produced or per dollar (or RMB) of GDP.

That said, at least China is building out some nuclear capacity. America is frozen on the issue.

I can use some of that. I'm teaching 1st and 2nd semester CS in January, and I don't want to overload them too much with philosophy of programming, but I plan on having code reviews be 20% of their grade. They'll have to come up in front of the class and talk about why they made the design decisions they did, and other students can earn extra credit by finding bugs and pointing out questionable decisions.

But yeah, I was planning on doing a maze solver, so maybe a A* solver might be a little more useful. Thanks for the ideas!

Comment 2 types of recruiters and 2 types of candidates (Score 3, Insightful) 253

There are 2 types of recruiters, those with "skin in the game" (like in house recruiters) and those only trying to make their quota so they can keep eating.

There are 2 types of candidates, those who need a job bad enough to work with any recruiter, and those that can get a job easily because they have "in demand" skills, they don't need (or want to deal with) the second type of recruiter.

Luckily, I'm the second type of candidate and I will never again deal with the second type of recruiter. I love captive recruiters, even if I don't particularly care to work for their company, and I will happily give them referrals if I can. But the independent recruiters are all scum, and I choose that characterization carefully, I've never met one that was not, though interestingly they all swear they are different than the others. I'm working on a form letter to send to the scum recruiters, but I'm too nice to actually send it, so I'll just continue to ignore them. Like telemarketers and spammers, I realize they need to make a living, they just aren't going to get any help from me.

Will do. Thanks for the input!

I plan on using some common computer science job application questions as homework assignments, like Fizzbuzz. A friend of mine applied to Facebook and was asked to test a string for being a palindrome, create a linked list class, and write a method to reverse it.

You do have any suggestions for such homework assignments?

>I can't tell you how many of these bozos who've learned in a "formal" setting can barely manage a coherent if/then statement, much less successfully complete even a small in-house application.

I'm going to start teaching CS in January. My approach will be to have the students writing code every class, which will be automatically tested by code that I write for correctness. If they can't get it done in class, they have until the next class (48 hours later) to finish it.

It is somewhat inspired by the code competitions I used to do. If a CS student can't write code to save his life, why is he taking a programming class?

>Granted, most of the self-taught crowd is weak on specialized algorithms and data structures

This is a bigger weakness than you think. Sure, some concepts like hashing and linked lists can be learned pretty quickly by an auto-didact, but the lack of formal training in discrete math means that their code all too often isn't correct. I can look at a recursive algorithm and immediately see when it was written by someone who never learned to do a proof by induction.

Also, their understanding of big-O notation is often (but not always) weak, and they'll tend to just try to use the one or two structures they understand for everything, which leads to inefficient implementations.

>Does not apply to sting operations...

Your reference says nothing about wire fraud.

Here's the actual law -

"Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises, transmits or causes to be transmitted by means of wire, radio, or television communication in interstate or foreign commerce, any writings, signs, signals, pictures, or sounds for the purpose of executing such scheme or artifice, shall be fined under this title or imprisoned not more than 20 years, or both"

It's malleable enough that prosecutors can make it apply to basically anyone.

Comment Models of the Heart (Score 1) 62

I used to work in the "new" field of computational medicine about 15 years. (Is 15 years new? I don't think so - and some of those heart models well before my time.) The Cardiac Mechanics Computational Group at UCSD, if anyone cares.

Personalized medicine was a very big driver for the models we were working on. You could introduce ischemias or other defects into the modeled heart tissue and observe how it changed the propagation of potentials across the tissue surfaces.

I personally worked on smaller models of just one heart cell, with the purpose being that you could see what the impact various drugs would have without needing to do millions of dollars of testing. Got a drug you know will change the sodium permiability or whatever? Alter the constant in the model, and run it. Proctor and Gamble funded the research that funded me, and was pretty happy with the results, I think.

Do the credit card companies hate that you pay your balance in full each month?

You (and I, since I do the same) are the ultimate easy money. The Visa/MC brands make money off the margin they get from each purchase and the banks make interest (and some margin), but the banks also collect interest. They charge a high interest rate because of the risk that you might default. You are very low risk and churn a lot of money through their fee-extracting process that they would not get if you paid cash.

Therefore, they still like you, a lot. Now, the people who always pay cash or use a debit card, those they hate (or more likely just ignore).
