Comment Re:Is Hawking up for the rigors of spaceflight? (Score 4, Informative) 77

I don't think Virgin Galactic's flight plan involves nearly the kind of g forces one experiences on a rocket. It's basically a plane that goes really really high. Take a look at the flight plan for SpaceShipTwo, which was the previous generation.. (The image came from here)

I really don't know what I'm talking about, so this might be TOTALLY wrong, but: It says it accelerates to 2500mph over 70 seconds. 2500mph divided by 70 seconds, in meters per second, is about 1.5Gs.

Comment Was Boston that far behind? Or is this propaganda? (Score 3, Insightful) 319

The insinuation that students never saw any map other than the Mercator projection seems unlikely. The implication that the map is some kind of Anglo-Saxon reality distortion field is borderline propaganda. Was there some kind of district-wide rule that teachers had to use the Mercator projection? Was the Boston school district really that screwed-up?

I went to school in Maryland, and we used Robinson and either Goodes or Boggs (I can't tell the difference). Our social studies teachers had 10 foot tall maps that they could pull down over the chalkboard like a blind. We had a unit where we went over different map projections and had to understand the differences. It is a classic elementary science demonstration to give kids an orange and challenge them to peel it and make it flat, or to take a sheet of paper and wrap it around a ball. Did none of this happen in Boston?

The article spends several paragraphs slamming the Mercator projection, as though it was news. It has an embedded clip from a fictional television show debating map projections. But this sounds like it is attacking a strawman here. The article presents no evidence to me to indicate that Boston school teachers really only used one horribly stupid map projection, that they didn't use globes, and that they didn't have curriculum to explain map projections. It seems more likely that the school board decided to standardize, and the site is exaggerating it into a civil rights issue to make it newsworthy. The Boston school district official is happy to take credit for a "paradigm shift" which just feeds into the whole exaggeration.

Comment Re:"Human Colleague"... Nope, You Just Don't Get I (Score 1) 407

I agree that an algorithm could recognize a human and put the robots into a safe mode. But Asimov's 3 laws were much more complex than that.

Asimov's laws are more like an attempt to codify moral behavior. Humans can't even implement those laws. The laws required the robots to know the future and anticipate indirect consequences of their actions. In one of the stories, the robots implemented the laws by creating a religion. In another, the robots had to anticipate an object that might fall and indirectly crush a human, but then they also recognized that there was a hidden failsafe that would prevent the human from getting hit. The robots had to balance different conflicting goals and make a judgement between doing its job and saving a human. The movie, although not Asimov's writing, gave other examples like that. It showed a robot deciding which of two people to save, or a robot deciding between saving lives and preserving a human's freedom and right to decide.

The AC was being an ass, but he is making a valid point. Asimov wrote "I, Robot" 10 years before the existence of "computer programming" as we know it. The microprocessor didn't exist yet. "Programming" was more like electrical engineering than software engineering is today.

there is no known way to implement such law

Duh, of course! But to criticize Asimov as having "blandly ignored" the limitations of computer programming is insulting to his intelligence and detracts from the point of the books. They aren't engineering books about implementation. They are imaginations about the moral implications of what could possibly be. If anything, his books explore the moral ambiguity of the 3 laws of robotics, and talk about how hard it would be to write such laws given the assumption of a perfectly logical being that could interpret them. That's what makes it science fiction.

Comment Re:Appeal to authority (Score 1) 222

You don't seem to have even a basic grasp of structural dynamics, fluid dynamics, or basic physics.

Rei posted coherent statements about physics, links to scholarly articles, and provided measurements. So Rei does indeed seem to have a pretty good grasp on those things.

You have the appeal to authority down pat, and a whole lot of BS.

You are the one who appealed to the authority of "Thunderf00t." Rei has made no appeal to authority that I saw. If I missed it, please quote it for me to show what I missed.

Comment Re:Devil's advocate (Score 2) 202

This is a valid theory and is worth considering. But Occam's Razor leads me to choose the simpler theory: that encryption is working. This is because the contents of this leak are consistent with other public information. Public discussion indicates that D-wave's quantum annealing computers can't run Shor's algorithm, so they are not useful for this (yet). There aren't attacks on AES that make it practical to break on classical computers (yet). So what we see the CIA doing is consistent with the current state-of-the-art encryption research. We see police using Stingrays, rather than decrypting traffic directly.

The other option requires that the CIA be suppressing encryption research from multiple companies and universities across multiple countries. It requires that they are requiring researchers to release fake papers. It requires them to not be using their encryption super-powers very much. All that is certainly possible - when the Allied Powers broke enigma they made sure to keep its use secret. But that would be much harder to do today. So I choose the simpler more consistent view as the real one.

Comment This is a continuous process, not one-time trainin (Score 1) 347

Accept that this isn't a single tutorial, but a continuous process of teaching and learning. And failing! Here's some tips I recommend:
1. Don't dump every best practice you can on them at once.
2. As you see individuals demonstrate these skills, have them present it to the group.
3. Use code reviews so that they are motivated to catch each others mistakes during reviews, then are motivated to not make those mistakes themselves.
4. Have senior members of the team demonstrate these practices and participate in reviews and mentorship.
5. Assign them work that will improve their best practices. Maybe cleaning up an existing module, documenting a particularly difficult area, or reading a chapter in a book and finding an example in your code base where it could have been applied.
6. Accept commentary and debate. There are always exceptions.

Comment Re:Locals preferred ? (Score 1) 239

You have the hiring process backward.

Have you ever heard of a situation where a company wanted to hire an H1B but ended up

You will never see a job posting that says:

Position: SOFTWARE ENGINEER
Requirements:
5 years of D++
2 years using WGF and Visual Baloney
Experience with Libux a bonus
Must be an H1B

So if companies are exclusively looking for H1B applications, they will not make it apparent that they are doing so.

Have any of you ever been hired instead of an H1B because you are local?

How would the applicant know? They don't get any insight into the other potential hires.

In general, there are 2 kinds of companies hiring H1Bs. The one type is contracting companies looking for massive cheap labor, so they just take the cheapest people. The other type is just looking for skilled contractors, and they don't care if they are H1B or citizens or what. Those companies pick the best applicant regardless of H1B status. It would only matter if it was a tie, because the H1B would be more of a pain to deal with. But in reality, ties don't happen. I've interviewed hundreds of software engineers, and never the team of interviewers not had reason to sway one direction or the other. Also, the interview team is generally not told if the person is an H1B applicant, and we don't care. I've also never had a manager say "Well, you chose candidate X, but I will actually hire candidate Y." If so, I might suspect a preference for the visa, or some salary negotiation thing went on. But so far I guess I've worked for honest people at honest companies.

The primary benefit a system like this is to defend against a hacker who downloads bulk credentials from a hack, then uses those same credentials on another site. This is how most hacks are done. Even a single character difference defends you in this case. But in your example, you were attacked by an individual who was targeting you. In that case, you need to use a smarter pattern. But most hacks aren't like that.
