The Design Flaw That Almost Wiped Out an NYC Skyscraper

retchdog Re:Math (182 comments)

uh, sure, except these aren't independent trials. to clarify, the event of being in a storm now, and the event of being in a storm one minute from now are almost perfectly correlated. this means you can't use the product rule.

by contrast, the event of a storm happening this year vs. a storm happening next year are closer to independent exactly because the blocks are bigger (a storm on Dec. 31 will make a storm on Jan. 1 more likely, but apart from that...).

your 'improvement' rests on assumptions which are not only unwarranted, but obviously untrue.

The Design Flaw That Almost Wiped Out an NYC Skyscraper

retchdog Re:Math (182 comments)

what? where the hell did you pull that from? why 1/e?

if a storm hit every two years, your method would give a probability of 0.393. what sense does that make?

Mathematicians Devise Typefaces Based On Problems of Computational Geometry

retchdog Re:What a waste of time and resources (60 comments)

I'm sure MIT would be thrilled to hear your opinions; they're really floundering and could use all the help they can get. Email them, they've hired people of your caliber before.

Idiot.

Mathematicians Devise Typefaces Based On Problems of Computational Geometry

retchdog Re:What a waste of time and resources (60 comments)

Martin and Erik Demaine are professors, not students.

Erik Demaine, in particular, is widely considered to be a genius, so perhaps it's fortunate that you have no administrative power over your alma mater.

UN: Renewables, Nuclear Must Triple To Save Climate

retchdog Re:Adding yet another box (432 comments)

Ah, yeah, fair enough, though the standby consumption of an xbox is also much, much higher than an appletv. The arithmetic is trivial, but I won't bother with it since I have neither.

UN: Renewables, Nuclear Must Triple To Save Climate

retchdog Re:Adding yet another box (432 comments)

The "embodied energy" of a laptop is about 1500MJ, so let's call the Apple TV+HDMI a generous total of 2000MJ. Shipping energy is relatively low and fits easily in the 2000MJ upper bound.

The Xbox360 uses ~120W to watch a movie, while according to ArcadeMan the Apple TV uses 6W. Thus you make up the embodied energy in about 2000000000/114 seconds, or about 200 days.

The Xbox One is a bit more efficient, using ~75W, for a makeup time of about 335 days.

Either one is less than a year, so if you want to minimize energy consumption, it seems like a good plan to buy an Apple TV.

Of course it isn't clear that this is the right thing to be doing, but if it is, the benefit seems obvious.

Ask Slashdot: Are You Apocalypse-Useful?

retchdog lol. ignorant nerd rage. (737 comments)

Pace the implication of the article, medieval musicians and other low-tech entertainers would likely be in high demand.

If electronic technology magically stops working (somehow), then judging by the amount of purchased and pirated music today, one of the most secure professions would probably be musician. And if technology is low, medieval music (or some synthesis of it and modern forms like jazz) would be the go-to.

Ask Slashdot: Are You Apocalypse-Useful?

retchdog Re:WHAT? (737 comments)

Yeah, if things are so dire that computers magically disappear for decades, the concomitant disappearance of advanced agriculture, etc., will mean the lingering miserable death of probably 90% of the developed world.

Like most doomsday scenarios, this is a masturbatory exercise. Things will end up either 1) like now, but worse in many ways or 2) utter decimation. In neither of these cases will your soldering hobby become the salvation of your village and earn you the respect and admiration long-denied you by our anti-intellectual society, granting you, finally, a day in the sun where the jocks pull you along on a rickshaw while Julie the prom queen gives you deep throat.

Yahoo DMARC Implementation Breaks Most Mailing Lists

retchdog Re:Darmok and Jalad (83 comments)

Obviously, he doesn't understand Picard's story. He's just being comforted by a newly-won ally, enjoying the bitter victory and what it might mean for the future of his people. What Picard is saying is basically irrelevant. It's simply a way for the character to celebrate and it emphasizes the themes of the episode, for one, that words have meanings beyond the literal or even evocative.

They may not have meant it that way, but it works.

Of course, it is completely impossible that a culture could develop space-faring technology, or even a fucking automobile, through such a simple language; the language would just be so information-poor, that it would be basically impossible to collaborate on anything beyond a wheeled cart. But most Star Trek episodes are total bullshit on a scientific level; it's just part of what you accept. They're simple fables and morality tales in spaaaaaace, nothing more, no matter how much obsessive neurotics fetishize it.

SF Evictions Surging From Crackdown On Airbnb Rentals

retchdog Re:Adventure holiday! (319 comments)

What mostly irritates me is the (few?) furries with the idea that their furry identity is legitimate, sort of like with transgendered folks. The thing is, we mostly understand what differentiates the human sexes and the technology, though primitive, is capable of making significant changes from one to the other. Transgendered folks use these technologies to various extents. Once the technology is mature, the label of transgendered will mostly evaporate, apart from the few who intentionally adopt an ambiguous sex. The thing that freaks people out, is that trans people today are kind of in an uncanny valley. Nonetheless, for whatever reason, this is an acceptable price for many people.

Now, the thing is, we also understand some of what differentiates humans from animals and while most of the technology does not exist yet, I haven't heard of any furry yet who has stabbed out their frontal lobes or at least cauterized their Broca's area. These would seem like reasonable steps to take, if you were "really" a leopard or whatever.

Ask Slashdot: Fastest, Cheapest Path To a Bachelor's Degree?

retchdog Re:a humble suggestion. (370 comments)

Nice false dichotomy, you fucking imbecile.

Did you read the article? He wants a degree as easily as possible, just so that he can make more money. If an accredited institution offered Bachelor's degrees in CS for sucking dick in the parking lot, I'm sure our erstwhile submitter wouldn't have bothered asking for anything else.

North Korea: Male University Students Required To Get Kim Jong-un Haircuts

retchdog Re:Haircuts are cheap (110 comments)

Risk is the product of probability and cost

No it isn't, you fucking moron. The product of probability and cost is the expected cost; risk is almost exactly the opposite. Risk is a measure of uncertainty; it's vague because there are many ways to define risk. For instance, one may define risk as the probability that seeking medical care will completely ruin you financially. It's easy to reduce this risk, even if it increases the average cost of medical care. There are many other definitions which I won't bother going over. The point is that you're an idiot. Don't use probabilistic lingo if you don't know what it means.

Fluke Donates Multimeters To SparkFun As Goodwill Gesture

retchdog Re:One better? Well, sort of. (250 comments)

They could sell them, and then use that money to pay for a new non-infringing shipment of (inferior) multimeters.

Of course since it's important for them to appear altruistic, they'll probably just give away a smaller number of (superior) multimeters.

$30K Worth of Multimeters Must Be Destroyed Because They're Yellow

retchdog Re:Did Fluke request this? (653 comments)

There are about 500 active trademarks matching the string "multimeter". I could go through them myself in a few hours manually, or about ten minutes if I could grep the records first for relevancy.

My conclusion is that Sparkfun are just incompetent. I'm sure they would have no problem paying their lawyers to enforce their trademark, but they plead for special treatment as a poor widdle small business when they're on the receiving end. Fuck 'em.
