High School Student Builds Gun That Unlocks With Your Fingerprint

Rostin Re:99.99%, eh? (583 comments)

Approximately 30,000 gun homicides occur per year in the US. Because they don't necessarily involve a homicide or even a shooting, the number of defensive gun uses is much harder to estimate. Wikipedia says that scholarly estimates are as low as 55,000-80,000 per year but may be as high as several million per year. http://en.wikipedia.org/wiki/D...

Companies That Don't Understand Engineers Don't Respect Engineers

Rostin It goes both ways (371 comments)

Engineers frequently are know-it-alls who prioritize what they personally find interesting or meaningful over what's important to the business. Indeed, if business priorities are considered at all, they are thought of as an impediment rather than the reason most of us have paying jobs. Then when their manager tries to redirect their work, they retreat back to their cubes to grumble among themselves (or a few million friends on /.) about how idiotic and hopelessly out-of-touch their managers are with the nitty-gritty technical details or their work. This way of thinking about management is so in-grained and common that there's a very popular comic strip about it.

Maybe if more engineers figured out how to understand and appreciate decision-making on the "business side" or at least gave the same benefit of the doubt that they expect to receive from managers, they would find that their relationships with their companies would not be so adversarial.

Berlin Bans Car Service Uber

Rostin Re:Uber is quite retarded (341 comments)

Regardless of who has to pay for the medallion, they are an artificial barrier to new competitors who wish to enter the market. They protect established companies at the expense of new ones, which stifles innovation and hurts everyone. Telling me to "get used to it" is silly. Laws can be changed, and when they are unfair or not in the public interest, they should be.

I don't know what you mean when you say "That is how things are!" Are you telling me that there are no ambulances in Berlin, and that when people are near-fatally injured and in serious danger of bleeding to death, they call a taxi to get to the nearest hospital? I admit I've never been to Germany, but I find that very difficult to believe.

Berlin Bans Car Service Uber

Rostin Re:Uber is quite retarded (341 comments)

Bottom line the extra license for the driver is cheap, perhaps up to 1000Euros, and as it is not a real cab, they don't need the cab permit from the city (AFAIK).

Uber's and Lyft's business model relies on individuals driving their own cars, many of whom do it part time to make a little extra money. A thousand euros is a very significant hurdle to someone like that. Maybe cab drivers should be required to obtain a special, more expensive license, but it's not convincing that this license is no big deal because it costs "only" 1000 euros. I'll take your word for it that Berlin doesn't require any extra permits, but FYI cities in the US usually require cab companies to obtain a so-called "medallion" for each taxi they wish to operate. There are a fixed number of medallions, which limits the total number of taxis. In NYC, when a medallion becomes available, it can go for upwards of a million dollars. In other large cities, the cost can be in the hundreds of thousands of dollars. It's clear why both city governments and established taxi companies are fighting tooth and nail to get Uber and Lyft kicked out of their cities.

Why? Because I don't want to bleed to death when a friend flags down a 'cab' and asks to get me to the next hospital and the stupid driver takes the third best route to the second closest hospital or needs 3 minutes to pick one from his navi.

Ridiculous. Regardless of whether an Uber driver is qualified to drive a taxi, a taxi is not an ambulance.

Berlin Bans Car Service Uber

Rostin Re:There's more to EU transport than cheapness (341 comments)

The EU has a lot of consumer protection laws designed to look after their residents (now there's a thought), a concept that is completely foreign in the US where it seems that only company profits matter.

I'm sure all of these laws exist only and exactly to protect residents rather than established companies, trade unions, professional organizations, and other political donors against upstarts like Uber.

Berlin Bans Car Service Uber

Rostin Re:Uber is quite retarded (341 comments)

Just because a law applies to everyone equally doesn't make it a good or fair law. I think most people would agree that some regulations of this kind are for the public good, while others only serve to unfairly protect established businesses by making it difficult for new competitors to enter the market.

Why Scientists Are Still Using FORTRAN in 2014

Rostin Re:I never thought about engineering and Fortran (634 comments)

I am not a software engineer, so my speculations here should be taken with an extra grain of salt. With that disclaimer out of the way, my understanding is that Fortran is falling out of favor mostly because scientific and engineering software is growing more complex. At the same time, we are depending more on its reliability, and it is being more widely used by people other than the researchers who developed it. Language features like classes and templates that make developing complicated, reusable, and maintainable code more tractable are baked right into C++. Fortran has some of these kinds of features, but they are almost an afterthought, and I've never actually seen an object oriented Fortran code in the wild. The main things Fortran has going for it, like native vector and matrix operations, complex numbers, and (arguably) greater speed, are no longer enough of a selling point.

Why Scientists Are Still Using FORTRAN in 2014

Rostin Re:Fortran is NOT the language of choice (634 comments)

I don't understand what you mean, so maybe some explanation is needed. Fortran may be a "scientific" programming language, but it was also the language of choice for engineers for a long time. The advantages that Fortran had over other, lower level languages were things like native complex numbers and built-in transcendental functions, features useful to both scientists and engineers.

Why Scientists Are Still Using FORTRAN in 2014

Rostin Fortran is NOT the language of choice (634 comments)

I have a PhD in engineering, and my dissertation involved writing lots of code. Now I work at a national lab in the US, and I and nearly all of my coworkers work on scientific or engineering codes of some sort. Although there is significant amounts of legacy code that was written in Fortran lying around (a project I work on uses a fortran library written in 1973), very little development is done in that language. It's all C++ or Python.

Cadillac Unveils Pricier Alternative To Tesla Model S

Rostin Re:The $5,000 gets you... (196 comments)

I think if they'd negotiated it for themselves, even the staunchest "Randroid" would have difficult objecting. The fact is, Detroit car companies had guns to their heads in the form of the NLRB. I would never blame the poor fortunes of American automakers solely on the fleecing they've suffered at the hands of the government-backed unions, but it's nonetheless obvious why Toyota chose to build their US factories in right-to-work states.

Neil deGrasse Tyson Says Private Business Will Not Open the Space Frontier

Rostin Smart Guy (580 comments)

Tyson is a smart guy, but probably out of his depth in this case. I doubt he's ever taken more than a couple of economics or business courses, let alone run a successful business on the scale of Paypal, SpaceX, or Tesla. Sadly, he's suffering from the same delusion that lots of people like him eventually contract. Being expected to comment as a kind of "public intellectual" on all things space and science related has given him the misapprehension that he can comment intelligently on anything, including things he doesn't know much about.

Ask Slashdot: Scientific Research Positions For Programmers?

Rostin If you don't have a family (237 comments)

Look into getting a PhD or at least an MS in the science you're interested in. In my (pretty limited, admittedly) experience, the developers who do the heavy lifting on scientific codes are PhDs. At the same time, very few (almost 0) freshly minted science or engineering PhDs have any experience developing software in a production environment, so as long as you aren't terrible at interviewing, I think you'd be a shoe-in at a national lab or a company that does this kind of work after you finish.

FYI, because you probably don't know this, getting a PhD in a hard science or engineering is usually free (to you). In fact, they even pay you to do it. The stipend will be a half or a third or a quarter of what you're making now, but it's enough to live on. The challenge of course is that with little or no educational background in geology or whatever, it's going to be harder, though not impossible, to get into a good PhD program. At the very least, they will expect you to take a few undergraduate courses in the beginning to give you the baseline knowledge that most of your classmates will arrive with. And I would urge you to shoot for a top 10 or 20 department. On the BS level, where you got your degree doesn't matter much (again, in my experience). Where you get your PhD matters a lot more. Of all places, academia should be a meritocracy, but in reality, people with PhDs can be really petty about these things, and your lineage matters. At the very least, many places that would hire someone like you only directly recruit at a limited number of schools, and those schools tend to be the best ones.

Another thing you might consider to help you get around this lack of science background is applying to an applied math program that has a scientific emphasis. I had a friend at The University of Texas who was in the computational science and applied math program there, and his research was about computational fluid dynamics. Maybe dig around on their website, or the websites of similar programs, to see if any of the faculty have research collaborations with geologists.

Hardly Anyone Is Buying 'Smart Guns'

Rostin Re:Smart guns... (814 comments)

I'm glad you asked. The answer, according to a preliminary report which was written at the request of the President and very recently released, guns are probably used for defensive purposes at least as often as they are used for criminal purposes. Here's a summary of a few interesting points made in the report. Point #7 addresses your exact question.

Electrical Engineering Labor Pool Shrinking

Rostin Re: Quite so! (401 comments)

Engineering coop positions and internships pay very generously in the US. On the other hand, the amount of useful knowledge and skills gained in such positions is pretty negligible, so I don't think the person you responded to was correct. They serve mostly as ways for companies to get tedious, low skill work done and to inexpensively vet potential future employees.

UC Davis Study Concludes H-1B Workers Neither Best Nor Brightest

Rostin Re:schadenfreude (353 comments)

As I pointed out in my reply to your other comment, you're wrong. CEOs are not in charge of their own pay. You are also still confusing the question of why CEOs receive the compensation that they do, which is fundamentally economic in nature, with "fairness", which is what you think their pay "should" be.

UC Davis Study Concludes H-1B Workers Neither Best Nor Brightest

Rostin Re:schadenfreude (353 comments)

Who approves the pay increases and golden parachutes?

Okay.

Oh yes the CEOs.

No, they don't. From the link:

If bosses set the salaries of their workers, who decides what the bosses earn? In a modern corporation, the task of setting the CEO's pay falls to the board of directors, typically a subgroup of board members on its compensation committee.

UC Davis Study Concludes H-1B Workers Neither Best Nor Brightest

Rostin Re:schadenfreude (353 comments)

You seem to be confusing two very different issues. My original claim was (worded a little differently) that employees tend to be compensated according to what the market will bear. If it takes a compensation package that includes raises despite poor stock performance and so-called "golden parachutes" to get and retain an executive, then that's the market rate. Companies apparently think it's a worthwhile arrangement. You, on the other hand, seem to be talking about what is "fair" in some subjective sense.

UC Davis Study Concludes H-1B Workers Neither Best Nor Brightest

Rostin Re:schadenfreude (353 comments)

That by itself is not an argument against what I claimed. For your convenience, I wrote:

What they can get away is what you're worth. If your services were worth more, someone else would steal you away with better compensation.

If executive pay is rising across the board (that is, every company is paying more), all that means is that the level of compensation required to keep an executive at a particular company is rising. You might argue that executive pay is greater than executive productivity, but that raises an obvious question: Why are they being paid that much? Are companies all stupid? It seems like these companies would realize at some point that they could offer lower pay and achieve the same results.
