Comment Interesting question (Score 1) 187

Reflectors with an effective collecting area under 4" are worthless. That's everything from the aperture to mirror. That's going to put you well over $50. Adequate reflectors don't exist under $250, except on special clearance.

You are better off buying a remotely controllable reflector with a webcam fitted to the eyepiece and having a group of kids take turns steering it. Firstly, it's cheaper overall. Secondly, you don't have breakages to worry about. Third, kids prefer nice, warm rooms to freezing pitch-black country parks well away from light pollution, hot drinks, facilities, ...

Not only is this more likely to be attractive to kids, parents who invest $50 in a group effort are much more likely to make sure they get their money's worth than if they spent the same amount just on their kid. It's all about the attitude of not wanting to pay for someone else's stuff. It's a vulgar, uncouth attitude, but that makes it easily exploitable for everyone's gain.

Comment Meh. James Lovelock's idea is better. (Score 2) 80

It's a very simple, even lower-tech approach. Unstable molecules are unstable, stable ones aren't. Life isn't capable of producing stable molecules from stable molecules. Something, somewhere down the line, therefore must produce unstable molecules.

If you use spectrometry and find a planet that has two or more highly reactive molecules (especially if they cannot coexist naturally), that planet has complex life. If you have one reactive molecule that breaks down in sunlight but is being refreshed, that planet must have at least simple life. If the planet has highly reactive molecules that don't readily form naturally, you have life that is nominally intelligent.

No requirement for any technology capable of generating a specific signature. No requirement for the absence of metamaterials. No requirement for a telescope big enough to detect the signature against natural variation.

SKA would be capable of detecting an alien civilization using Lovelock's method anywhere inside of 1,000 light years, given the size and sensitivity currently being proposed. How big would the James Webb telescope need to be to get an IR signature on the industrialized part of the US at that range?

Despite the URL, that page only talks about individuals, not companies. Can you show me I'm clearly wrong for companies? Additionally it says the states do their own thing as well and some simply ignore tax treaties.

That said, I might well be wrong! The US tax code is notorious for being amongst the worlds most complicated, in fact it probably is the most complicated tax code in the developed world at least. So if I'm wrong that would not be surprising, although even if your statement is correct for companies too it still amounts to paying tax on the same income twice. Even if it's at a lower rate than US income, this is nonetheless double taxation.

The USA is unique in considering all income earned anywhere to be taxable in the USA, even if that money never actually touches America. No other country has a tax system that works like this, perhaps because it's stupid. Instead they have double taxation treaties so if money is earned abroad and you pay taxes there, you can spend the money back home at your HQ without it being taxed a second time. America doesn't, so companies that earn a lot of money abroad simply don't spend it on their HQ. They find things to spend it on in other countries instead.

Really, you're don't see the difference in added risk between (a computer taking over sole responsibility for the control of a 2500-pound, 65-mile-an-hour car, in all possible traffic conditions), and (adding a strip of reinforced fabric to the cockpit)?

Comment Ooops! (Score 3, Funny) 173

Found a bug in physics.c, those cars we mass produced last year will spontaneously explode after 367 days of exposure to an atmosphere containing oxygen, or when white lines are painted rather than vinyl, or when attempting a corner of a prime number of degrees when speeding on a cambered road.

Why wasn't this spotted sooner?

Because we hadn't expected to need chemistry or non-Euclidian geometry in a physics engine.

Then make the episodes longer. Or have one set of presenters on the first show (they're usually paired) and the others on the second show. Or eliminate redundant footage so that you can have two or three times the content. Or eliminate the advertisers, sorry adverts, and get three times the running length.

And remember their bible demands the murder of the Infidel there is no well maybe it can be read this way or that way. It black and white demands it.

First of all, [citation needed].

How does one fight against someone following their religion and teaching?

Did you know that the Christian Bible also "black and white demands" that anyone caught working on a Sunday be put to death? (citation). And yet somehow we don't see a lot of killings of Sabbath-breakers. So most clearly people can distinguish between the applicable and non-applicable parts of their holy texts. (Those who cannot we call "fundamentalists", and they are the problem; not every religious person in the world)

Discovery got caught using fake footage in documentaries. No scientist should be working with a channel that is peddling fraudulent material. History lost a lot of reputation with their academically bogus Ancient Aliens stuff, but at least they didn't try to offer photographs and videos they themselves doctored as "evidence".

If the three have projects worth taking seriously, they won't be projects on Discovery. HBO has less of a credibility issue.

Surely that's the very question they asked, and are not hiding it? I mean that's what the article flat out says, right? People want to both hire and work with the top people regardless of where they're from, and the general US attitude towards issuing foreign visas makes it hard to hire the top foreign guy and practically requires you to hire the mediocre guy just because of where they're from?

So, what, I'm supposed to sit back and accept an attitude of 'fuck U.S. workers, they all suck, we'll hire from overseas because they're better'?

That's not what he said. He said the best workers are not ALL from the USA. Guess what? He's dead goddamn right and who the hell are you to get pissed off because someone who runs a business pointed out the obvious, bleeding truth - America does not have a monopoly on software engineering talent, far from it? That means it's totally expected and understandable that given a choice between some American workers and some foreign workers, that employer might legitimately prefer the foreign workers because they are better than you are?

If this makes you mad then you need to learn about anger management. If you think it's all about working cheaper (which US law makes illegal anyway) then you need to get your head out of your ass and realise that foreign workers are hassle, can be expensive, and can still be worth it if they are better than you.

Comment Re:"Culture in tech is a very meritocratic culture (Score 1) 441

Tech skills are hard to objectively verify. Technical results are hard to objectively verify. We collectively proxy that by having lots of tests, competitions, selection, and other heuristics. But that's not a symptom of us respecting skill more than other jobs(maybe more than other specific office jobs, but not more than lawyers, doctors, manufacturing technicians, similar things), it's a symptom of it being really hard to tell.

How many technical interviews have you done, as an interviewer, in your life?

I have done about 220. Evaluating technical skills is dramatically easier than evaluating many other types of skill, in particular, it's a lot easier than evaluating skills in management, marketing, customer service .... anything with a large component of soft, people skills. You can ask a technical person to achieve a very specific, tightly scoped technical task during an interview and if you know the question well quickly get a feel for how good they really are. I wouldn't want a hiring decision to be made based on just one interview, but in the hands of a good interview it still yields valuable data. For someone without specific technical skills you end up having to rely on much vaguer and more gamaeble questions like "Tell me about a time you overcame a problem of type ", the answers to which are both hard to verify and easily manipulated by people who want to make themselves look good.

I'm afraid I must agree with the original statement. The difference between someone who is merely OK and is great, well, that's huge. Someone who is merely OK will come in to work each day and will (probably) resolve the bugs or implement the features you set them. They will probably not come up with a solution that puts you ahead of the pack. They may waste large amounts of time on trivial things or produce something that sucks because they are only familiar with technology X but that's a poor fit for problem Y. Their technical judgement may be flaky - in the worst case you will have to spend a lot of time double checking what they're doing, yet they will start demanding more responsibility because they've stuck around for a while. The very best will teach you algorithms and techniques you never knew about. They'll come up with the unique feature that makes you stand out from the competition. They'll be fun to work with and help you recruit other great people. The difference is not to be sneered at.
