Mathematicians Are Chronically Lost and Confused

ldobehardcore Re:Failing as a math teacher (114 comments)

When I was in high school, I was very good at math but couldn't be bothered to actually apply myself and take the highest level classes. I picked up everything pretty quickly, and I remember it being hellish when the teacher would say "break into small groups." Nobody cared to actually do the work. Most of the time it would be me and 1 or 2 other people in the class who actually got the concept, and everyone else would beg us to let them just copy off of me. I never consciously let anyone copy off of me. Most of the time, the other people who got the concepts would let everyone copy off them though. To this day that kind of laziness sticks in my craw, and I simply refused to let people copy. I offered to re-teach the concepts one on one, with the stipulation that they teach what they learned one on one to the others. This made it so I only had to re-teach the class once, then I could do my own homework. It was nice in that I was recognized for my abilities, and I was a decent teacher. I'll be damned if my students just copy off of me, so I did my best to make them prove they could do the math along the way. I think the biggest problem was probably that none of my math teachers actually gave a damn about math. They were all football/basketball coaches, and teaching math was just their night job, really. So the jocks and the cheerleaders always got passing grades, (at least C-) and everyone was left to flounder, since the coaches were too busy chatting with their favorite quarterbacks, pointguards, and cheerleader captains.

Do You Need Headphones While Working?

ldobehardcore Re:Even without anything playing they're useful (262 comments)

Oh man. If my office had noise generators my sanity would crumble so quickly. It's bad enough my semi-cube is 10 feet from the corporate server closet, but if I had to deal with non-localizable static all day I'd be raving like a lunatic. I have pretty bad tinnitus from a youth full of fireworks and raves, and it'd probably get so bad I'd might as well be deaf in that kind of environment.

D-Wave Quantum Computing Solution Raises More Questions

ldobehardcore Re:you misquoted my quotation directly heres proof (143 comments)

properly understood, Quantum Entanglement is at the core of all Quantum Physics

To a US English speaker, this phrase can generally be translated to mean "All quantum mechanical reasoning relies on quantum entanglement" which is false. But the phrase you state leaves room for interpretation and can certainly mean "quantum entanglement is one of the basic features of quantum mechanics" or even "quantum mechanics requires quantum entanglement to be true". It's just that the standard way the phrase is parsed makes it seem you're saying entanglement is the most important or most fundamental feature of quantum mechanics. You aren't wrong, but the way you expressed yourself can be a little confusing.

Linking Mass Extinctions To the Sun's Journey In the Milky Way

ldobehardcore Re:Rubish (199 comments)

While technology and technological knowledge could certainly weather a large portion of the population vanishing, what do you think of the economic implications of a significant impact event?
How would the global economy react to a mile-wide rock hitting Manhattan? Or Hong Kong? Berlin? Tokyo? Any large city?
I have the feeling that there would be a global economic upset the likes of which has never been seen.

NSA Admits Searching "3 Hops" From Suspects

ldobehardcore Re:Can we discuss the fourth amendment now? (322 comments)

I don't disagree with the general premise that the NSA would resort to torture if they thought that it would be in their best interest.
I'm stating that since the NSA isn't exactly a military organization (in a strict sense), and since the NSA is known for using applied science, it would know that torture (or more specifically pain driven interrogation such as water-boarding) doesn't give reliable results when it comes to intelligence gathering. It's a fine line. Overt torture causes the subject to say whatever they think will make the torture stop. Too mild, and the subject won't give up the goods. Legitimate interrogation methods are far more effective than torture in secret, when it comes to getting information vital to national security. It's been discussed in many venues and on multiple occasions that torture isn't effective in helping intelligence organizations do their jobs.
The NSA has been so corrupted by the mandate of its task that it has decided to "gather all intelligence" but this is both simply infeasible (since one-time-pads and horribly inconvenient methods of encryption exist), and ultimately a waste of energy and time.
They can record everything they wish, but I'm not sure it will make a difference in fighting terrorism carried out by those who have a moderate education in information security and encryption. Granted it's not particularly easy communicating in a way that's secure against a government organization bent on destroying all semblance of anonymity, privacy, or security in one's person and effects, but it's certainly not impossible.

Sorry if I'm being too literal here. I just hate ambiguity. So I'm defining my terms.

ldobehardcore Re:Can we discuss the fourth amendment now? (322 comments)

Mod this guy up. The NSA may not be looking for you specifically, but that doesn't mean we shouldn't be mad as hell that they're violating everyone's rights. They aren't torturing you at a black site now, but they could if they wanted to, because they have conspired to make themselves above the law.

Police, Copyright Industry Raid Movie Subtitle Fansite

ldobehardcore Re: Fuck 'em (344 comments)

I assume it's illegal to make a copy and give away the original while retaining the copy. But what is true is that it is legal to make copies for personal use. Every 5 years the librarian of congress reviews requests for exceptions to the DMCA and this last time decided to allow copies for personal use and backup of DVDs as an exception.

ldobehardcore Re:Fuck 'em (344 comments)

that is a marginal loss to the owner of the copyright

You can't assume that's true. The friend the disk was loaned to may never have bought the movie. It's not a loss if the purchase wasn't ever going to happen. And like you mentioned, it might equally be considered a marginal gain, because the borrower could recommend the movie to others, and cause purchases that otherwise may not have happened.

Police, Copyright Industry Raid Movie Subtitle Fansite

ldobehardcore Re:Fuck 'em (344 comments)

Are you serious? Or trolling? You can copy the DVD image super easy, bit-for-bit, without breaking any encryption using a program like ImgBurn, and right now it's legal in the US to do so for personal use. You can then play it back on your computer legally using an ISO mounter like DaemonTools, and a legal DVD player program like PowerDVD. This is a legal chain of use. It's legal to backup a DVD by making a bit-for-bit copy of the disk. It's legal to mount the ISO of that image. And it's legal to playback that ISO with a piece of decryption software that is correctly licensed for it.

ldobehardcore Re:Yes, all works are derivative. (344 comments)

They can sue if they can show that your work is a derivative of the Disney work

Not exactly true either. They can sue without of the evidence of infringement if they're so inclined. They'll lose if the evidence is against them, but they'll still put a heavy financial burden on the party they'll sue. If Disney thinks they can bankrupt the defendant, and it's worth the cost, then they can sue with practically no standing.

That's why corporate ownership of copyright is a financially asymmetrical and unfair legal allowance. The richest media companies can buy up whatever properties they want and then tie up smaller parties in a civil suit subsequently incurring disproportionate expense on the defendant. They can then offer a settlement deal, and give the smaller party a cheaper option than winning in court. If Disney loses in court, it's objective is still realized by the bankruptcy of the defendant. If the defendant instead settles, they promise to censor their work irrespective of whether or not the work was infringing. If Disney wins, it gets to expand the scope of its intellectual property and bankrupt the defendant. Its a no-lose situation for Disney if the value of the defendant's property is equal to or greater than court costs.

NASA's Polar Robotic Ranger Passes Test In One of Earth's Harshest Places

Titan's not a planet, but it's fairly nearby (ie within the solar system), and has rain and mud. As long as you count liquid methane and ethane falling from the sky as rain, and tholin tar as mud.

Volkswagen Concept Car Averages 262 MPG

ldobehardcore Re:We need a new class of 'ultralight' cars (353 comments)

As far as I know, modern cars are designed to crumple, and smash externally in order to dissipate shock in an accident as much as possible.

For instance, if you have a very rigid-bodied vehicle and a crumply-bodied vehicle, you'll most likely experience more acceleration in an accident with the stiff bodied vehicle, as the crumply vehicle takes more time to come to a complete stop. Going from 60mph to 0mph in 100 milliseconds exerts ~27.34G on the occupant. If you can double the period of acceleration from 100 milliseconds to 200 milliseconds, you can half the G load to ~13.67G, which is much more survivable.

I don't know how much the crumple zones and pliability of the frame contribute exactly, but in life or death situations every little bit counts, as far as the highly risk averse public is concerned.

FreeBSD Team Begins Work On Booting On UEFI-Enabled Systems

ldobehardcore Re:Why not promote motherboard manufacturers (248 comments)

Try all the F# Keys. It might take a while, as they might have set the pause for FKeys to be something braindead stupid like 1/3rd of a second or some bullshit like that. so try all of them: F1 Through F12. If none of them work, and neither Delete nor Escape, nor the Space Bar works, then I gotta say you've wasted your money.

Although, there might be a jumper on the mobo (literally a couple of prongs bridged with a piece of plastic holding some foil) that you can break and refit that can reset your bios so it'll tell you what buttons to push.

Also, try unplugging your HDD and see what the error screen says. It may tell you what to hit on startup in order to get to your UEFI/BIOS.

FreeBSD Team Begins Work On Booting On UEFI-Enabled Systems

ldobehardcore Re:Well I'll be... (248 comments)

Too bad the user can't manage his own hardware now. We're at the mercy of the mobo manufacturers, as they decide who's keys are trusted by default (ie microsoft ONLY). If I have to go to microsoft in order to be allowed to boot BSD on my own motherboard, then my property rights are being violated. I'm not leasing or borrowing my mobo, I've bought it. That means nobody else has a right to tell me I can't do whatever I want with it (within legal limits).
The only feature of UEFI so far is to wrest control from the actual owner of the hardware. This is just as bad as DRM. Nobody woke up this morning and said to themselves "I wish I could buy a desktop computer that let me do less with it than my current machine." Nobody goes to iTunes thinking "I wish I could buy a song that plays on fewer devices than what I have" and nobody thinks "I wish I could buy a movie that plays on my cellphone, but I sure would be pissed if it could play on my TV, Kindle and laptop too"

UEFI so far is only a bad thing. I currently own a motherboard that claims to have "dual uefi" whatever that means, and I still can't disable secureboot even with a manual. That's simply not an option. The manufacturers, in collusion with microsoft, have figured out a way of forcing me to use windows 8. I don't want to use windows 8. And my only alternative is counting my current mobo as a loss of $120, and buying either a used mobo (who knows how damaged it is), or a mobo that's been sitting in a warehouse a few years (better than the former, but still iffy. Why are they there in the first place? Why haven't they been sold yet?)
