Rosetta Code Study Weighs In On the Programming Language Debate

PJ6 Re:Compiled Strongly-typed Languages -vs- Scripts (165 comments)

I think the test-driven advocates would say that relying on the compiler is OK for that one particular kind of error, but you really should be writing tests to catch that kind of error along with many others.

The reality is probably, as you kind of imply, sometimes you have a task that is more suited to one approach or another.

The nature of testing is that complete coverage grows combinatorially with state. What you're saying is you don't want to eliminate the possibility of an entire class of errors, but rather rest this (rather significant) burden on testing. From my point of view that's like abandoning DRI in a database and saying tests can detect foreign key constraint violations and all the other things DRI can check. While technically true, it just doesn't make any practical sense.

New "Crescent Bay" VR Headset Revealed and Demo'd At Oculus Connect

PJ6 Anyone know what the resolution is? (65 comments)

All I can find is that the resolution is "higher" than the DK2, and the screen door effect is gone, or nearly so.

Can anyone confirm that they've gone to 4K?

The Future According To Stanislaw Lem

PJ6 not really (196 comments)

Niven's view of such devices seemed pretty realistic, that the problem would take care of itself after a few generations.

Even if you were immortal, a droud would still be equivalent of death; remove the constraint of time, and limitation is measured by the boundaries of your mind's total potential state-space.

Any sufficiently intelligent being - no matter how powerful or long-lived - would avoid pleasure-death.

How the Outdated TI-84 Plus Still Holds a Monopoly On Classrooms

PJ6 Re:RPN FTW (359 comments)

Amen. I got mine back in 92, and remember everyone making fun of the kids who went with a TI because RPN scared them.

Now that I think of it, that was a good dropout predictor.

I still have mine and I love it.

Low-Carb Diet Trumps Low-Fat Diet In Major New Study

PJ6 study is misleading (588 comments)

What is not mentioned is that these low-carb and the low-fat diets were both done in the context of the typical, and rather terrible, Western diet. Since no distinction is made between simple and complex carbs, naturally 'low-carb' is going to win, since sugar is the worst offender for creating obesity.

I also have to roll my eyes because we already know what a healthful diet is. The most massive study of this kind in history came to a simple, unambiguous conclusion: eat a whole-foods, plant-based diet, and keep animal protein under 10% (even better, 5%) of your total calorie intake.

The Grumpy Programmer has Advice for Young Computer Workers (Video)

PJ6 Read his blog and lost interest (120 comments)

when I discovered that he doesn't bother to proofread or use a spell checker.

I don't care how long he's been doing it, sloppiness is a sign of a poor programmer.

New Nail Polish Alerts Wearers To Date Rape Drugs

PJ6 no working product exists (595 comments)

I see only stock photos. If they had anything at all working they would have released either a video demonstration, or before-and-after pictures.

What they're attempting is non-trivial - I'm going to go out on a limb here and say that they're going to fail on the chemistry.

New EU Rules Will Limit Vacuum Cleaners To 1600W

PJ6 Needs better metric, not a restriction on wattage. (338 comments)

Consumers want number(s) to base their decisions upon. The wattage problem could have easily been solved by putting useful measurements of vacuum effectiveness on the packaging, such as guaranteed pressure drop and flow rate over the life of the product.

And the industry could do that all by itself without any regulation.

"MythBusters" Drops Kari Byron, Grant Imahara, Tory Belleci

PJ6 Re:Perhaps this won't be a popular view... (364 comments)

But I think it's a good move. I always thought they were trying to do too much in one episode. And really, who can argue with focusing on two really awesome dudes who love to blow stuff up?

More isn't always better, sometimes its just more.

Too much in one episode? Are you kidding me?

There's a lot of unnecessarily repeat after commercials and switching between myths. This is particularly annoying when watching on Netflix, where there are no commercial breaks.

Most episodes could be dramatically improved by cutting their length by 30%.

Solar Plant Sets Birds On Fire As They Fly Overhead

PJ6 Re:"1,416 hectares" (521 comments)

A hectare is a metric unit. Not that most people have a problem with imperial measurements, just people who think it's cool to complain about it.

When Customer Dissatisfaction Is a Tech Business Model

PJ6 Re:Free market (257 comments)

Don't worry guys, the free market fairy will take care of it.

The free market has taken care of it. Good customer service is expensive. Consumers have demonstrated that they are unwilling to pay additional money for good customer service. Successful companies have aborted customer service to keep prices low.

Tell me how having one ISP to chose from is "free market".

Dramatic Shifts In Manufacturing Costs Are Driving Companies To US, Mexico

PJ6 Re:Zooooom! (233 comments)

I'm gonna disagree.

This is supposedly a sign that the race to the bottom is actually done. The bottom filled out and is rebounding, and "we" mostly resisted our worst political urges vis-a-vis protectionism and removing regulatory protections that exist for good reasons. An equilibrium has been reached, and all the sacrificing has been mostly of the short term kind.

The problem with deregulation is that it was applied ridiculously unequally, greatly contributing to income inequality. For example, while unions were being busted up all over the country, doctors successfully bought legislation to make it much harder for foreigners to come practice medicine in the US - legislation that to this day keeps your medical bills artificially high.

And income inequality, when it goes past a certain point - far from being merely a social problem - can be quantified as massive, long-term economic damage.

Dramatic Shifts In Manufacturing Costs Are Driving Companies To US, Mexico

PJ6 Re:Growing pains. (233 comments)

My point there is that democracy, while important, isn't a cure-all. It's inherently adversarial, a conflict which has notably ground today's national legislature to a standstill.

I'm going to disagree with your point. The founders of the USA designed gridlock into the system, so that if there isn't agreement on what to do, nothing will get done.

Are you worried about theocrat conservatives? Don't worry; they will never get any of their goals accomplished.

Are you worried about liberals completely turning the country into a socialist country? Don't worry; there is a point past which they will never be able to go.

There's only gridlock for the issues that the powerful don't care about. For the other stuff, there is no meaningful public input or interference.

Humans Need Not Apply: a Video About the Robot Revolution and Jobs

PJ6 Re: The problem with the all robotic workforce ide (304 comments)

We've already tried that. Hoover after the 1929 crash let the free market work on its own. After 3 years of worsening depression, the people wanted a New Deal.

But it wasn't a free market. The FED - the very concept of which is antithetical to a free market - deliberately crashed it.
