In IT, Beware of Fad Versus Functional

Calavar Re:Some practical examples (153 comments)

everyone realized that Ruby is awful

I'm tired of hearing this. Ruby is not awful. It's a wonderful language, and Rails is a wonderful framework. The problem is that Rails is designed for a very particular niche (small, fairly CRUD-oriented web applications), and people keep trying to stupidly shoehorn it into places where it doesn't work well (large, enterprise applications that need to do lots of heavy number crunching or querying of enormous databases in the background). Predictably, such projects end in a trainwreck and then people blame Rails, but Rails wasn't the problem.

Rosetta Results: Comets "Did Not Bring Water To Earth"

Calavar Re:The wet ones did! (135 comments)

Either way, GGP's assertion that mass is relevant but weight somehow isn't makes no sense.

Rosetta Results: Comets "Did Not Bring Water To Earth"

Calavar Re:The wet ones did! (135 comments)

Weight is defined as the force of gravity that is acting on an object. When you are in orbit, weight is serving as the centripetal force that is keeping you on a circular orbit. So if an object was weightless, it would fly off in a straight line instead of orbiting. GP is almost right. The weight of the space ship is going to be much greater than the weight of the astronaut inside simply because the spaceship is more massive (and F_g = GMm/r^2, so weight increases linearly with the mass of the orbiting object), but the astronaut feels weightless because he/she has the same acceleration as the space ship.

Rosetta Results: Comets "Did Not Bring Water To Earth"

Calavar Re:The wet ones did! (135 comments)

No, it doesn't.

F_g = GMm/r^2

F_c = mv^2/r

Combine the two, and you get

GM/v^2 = r

So the orbital radius of an object around the sun depends only on the mass of the sun and the velocity of the object. The mass of the object doesn't matter. This is high school level physics, buddy.

James Watson's Nobel Prize Medal Will Be Returned To Him

Calavar Re:why should he have it (235 comments)

Middle East? What in the world are you talking about? Kissinger got the Nobel Peace Prize in 1973 for the American withdrawal from Vietnam. (And ostensibly for brokering peace between North and South Vietnam, but we all know how long that lasted.)

Keep in mind that in 1970, Kissinger was the one who pushed for expanding the Vietnam conflict into Cambodia. Around the same time, he was also working with the CIA to try to overthrow the democratically elected government of Chile. In 1971, he had the US throw its support behind the Pakistani government, even after a US diplomat in Pakistan said that the government engaging in widespread genocide of its own citizens.

Did I think Obama deserve the Peace Prize? Probably not. But at least the committee didn't decide to give it to him while knowing that he was complicit in genocide and active in coup d'etats.

Obama Offers Funding For 50,000 Police Body Cameras

Calavar Re:not enthuisastic about this (262 comments)

Pervasive surveillance by law enforcement is a bad thing. Pervasive surveillance of law enforcement is a good thing. And that is what these body cams are: They aren't recording anything that police officers aren't already seeing with their own eyes. Instead, these cameras create a record of officers' actions -- a record that keeps them accountable for said actions.

There is a big difference between "was born in 1901" and "published novels and short stories in 1901." No one who is alive today knew Arthur Conan Doyle.

Russian Military Forces Have Now Invaded Ukraine

Calavar Re:Cut the Russians Off (848 comments)

Again with all these conspiracy theories about Western involvement in Ukraine. The thing about conspiracy theories is that they never hold up when you apply common sense.

There is only one major nation for which the situation in Ukraine is of critical importance: Russia. If EU membership led to a flood of Gean, French, and British investment in Ukrainian oil production, Russia would no longer have a monopoly on oil exports to the rest of Europe. This would be a disaster for the Russian oil oligarchs that keep Putin in power. From the perspective of EU businessmen, however, it matters little whether they invest in Ukraine or Russia. Meanwhile, the average American probably wouldn't even be able to point Ukraine out on a map.

So who has the vested interest in interfering in Ukrainian politics? Moreover, who has a history of interfering in Ukrainian politics? That's right, Russia. Are you forgetting that the KGB tried to assassinate Yushchenko in 2014? Of course Russia and their lackey Yanukovych claimed that Yushchenko poisoined and nearly killed himself to win sympathy from voters, because that is something that a sane person would do. (Note the heavy sarcasm.)

So no, the protests in Kiev were not engineered by the CIA; they were grassroots. Just because you read it on RIA Novosti, doesn't make it true.

Russian Military Forces Have Now Invaded Ukraine

Calavar Re:Baltics are next if the West fails to respond (848 comments)

Unarmed protesters getting shot and killed by government police is a "violent overthrow of the government"? Your utterly warped "memory" of events is disgusting. As far as this conspiracy theory about US involvement, find me one person in Kiev who acknowledges the presence of CIA. I doubt you will find a single one, but there are dozens of rebel leaders in Donetsk who are proud to say that they have KGB handlers.

FCC Warned Not To Take Actions a Republican-Led FCC Would Dislike

Calavar Re: Correction: (338 comments)

If you're one of the select few that are so wealthy that you own enough stock to be able to vote out an unpopular CEO (or block a grassroots shareholder movement to do the same), you're either the CEO or his yachting buddy.

Yes, and liberals such as myself contend that marriage is a human right. If tolerance means allowing gay individuals to have human rights, then they must have the right to marriage.

Are Altcoins Undermining Bitcoin's Credibility?

Calavar Re: Not credible enough for merchant's to hold ... (267 comments)

You're missing the point. If Macy's sells a shirt for 50 USD and decides to keep those 50 USD in the bank, are they "speculating on the value of the dollar." Technically yes, but that certainly isn't how Macy's is thinking about it. The USD is is stable enough that holding onto USD is not considered speculation or investment. It is considered saving. That's what it means to be a currency. Until Bitcoin can also act as a medium of savings rather than a medium of speculation and investment, it will not truly be a currency.

The Flight of Gifted Engineers From NASA

Calavar Re:Not Surprising (160 comments)

Geez, this is the most idiotic comment I've seen on Slashdot all day, and that's saying something. You couldn't be bothered to do a 30 second web search before implying that Apollo had no benefits?

Examples from those links: improved dialysis machines, credit card swipes, army field rations, improved building insulation, low recoil/shock rubber, cordless household appliances, cheaper Teflon and Velcro, asbestos-free fire proof textiles, better industrial lubricant, exercise equipment improvents used by pro sports teams, a great deal of insight into how the moons and planets formed, many rocket technology advances used in today's ICBMs and missile defense systems, etc., etc., etc.

Please, next time do five minutes of research before you post something so bonehead with so much conviction.

Swedish Dad Takes Gamer Kids To Warzone

Calavar Re: Gettin All Up In Yo Biznis (419 comments)

You seriously think the DoD never spent recruiting money on comic books and movies? I'm guessing you never heard of GI Joe then? OrTop Gun? Should we send every kid who likes GI Joe and Top Gun off to Gaza? I liked playing with toy GI Joe fighter jets when I was young. Should my parents have taken me to Kosovo? No, videogames are not any different from movies comics an television. This is just another example of the age old phenomenon of an older generation being afraid of the culture of the younger generation because they don't understand it.
