I'm running an old version as well. I've actually not even tried to record video with my T2i since I got it years ago, and after visiting the ML website just now, I'm surprised (and excited) to hear that ML is primarily lauded for its video recording features. Curious to see what makes it so awesome, as I really can't fathom what kind of features might apply in the video realm.
Magic Lantern is fucking awesome. It turned my Rebel T2i (550D) into something that I definitely wouldn't have been able to afford. If you own a Canon DSLR, you owe it to yourself to give it a try. You'll be amazed, confused, and then even more amazed.
That being said, the cameras mentioned in the summary cost more than all my lenses combined. Sounds like an awesome feature, but not one that will be available to casual photographers.
For the enhanced pat down, you're explicitly told to remove everything from your pockets. It would take an especially incompetent TSA agent to not notice the lighter still in your pocket.
Perhaps you didn't opt out of the naked body scanners? I know people have walked through those with large knives and didn't get any grief from the TSA, so I wouldn't be surprised if something like a lighter got through as well.
As a smoker, I've been flying with lighters since before 9/11. I was only told I couldn't bring my lighter once, and it was the time I had it on me when I opted-out and got me an enhanced pat down. In my experience, as long as it's in your carry-on bag or just not on your person in general, it's not a problem.
You're playing with words. Yes, we have juries. Yes, the people in our jails are convicted of committing "crime".
My point, since you've obviously missed it, is that we criminalize more behaviors and our sentencing is more extreme. That people end up (and stay) in prison for victimless crimes like drug smuggling only further backs up my claim.
The fact that you bring up school shootings just goes to show that you have no idea what you're talking about. School shootings account for a statistically insignificant amount of crime. You might as well talk about hammer attacks (which, incidentally, kill orders of magnitude more people every year than do school shootings).
Stop worshiping the talking heads on your television screen and look at the fucking numbers, man. If you honestly think real crime is more widespread (and laws more poorly enforced) here than, say, in Cuba, or Russia, or China, or Papua New Guinea (!!!), then you are ignorant of reality.
You live in one of the safest countries on Earth by any metric, at one of the safest points in time in history. To complain about a lenient justice system is comically wrong.
A former friend of mine is a corrections officer. I say former because nowadays, he's a fucking dick. See, he used to be cool. An easygoing fat dude working at a pizza place. At some point, that changed. He hit the gym something fierce and went from rotund to ripped in no time. Before I knew it, he was working at a local prison. Telling stories of abusing the shit out of [insert various racial slurs here] with fellow COs simply for the amusement of it. Perhaps he was a rotten asshole on the inside all along. Perhaps being around dickhead COs 40+ hours a week rubbed off on him. Either way, it's clear to me that the culture among prison staff is not something I'd want to be a part of.
And because of all that, I'd take anything "guards" say on video with a grain of salt. Their Blue Code of Silence is even worse than cops'.
I know others have already gotten this point in, but I can't help but express my disgust with your description of our justice system as lenient.
Either we have the most draconian "justice" system in the world, or Americans are significantly more criminal than anyone else in the world. Citation.
Bonus: If you go back to the pre-Reagan glory days, you'll notice that our incarceration rate wasn't nearly as ridiculous. This suggests that either Americans aren't inherently worse than anyone else or that Reagan brings out the worst in everyone. Or our "justice" system was replaced by a prison system.
I suppose this would be a good time for a [US or other common law country] lawyer to chime in.
It is in many cases illegal to steal "an e-coupon at best". Industrial espionage is criminalized in many places, even when all you're "stealing" is 1s and 0s. It's criminal even if you don't do anything with the stolen data (and thus the original retains full value and the victim suffers no material loss). In the case of bitcoin theft, if the stolen coins are spent, the original becomes worthless, thereby causing material harm to the victim. Grounds for a civil suit at the very least, but indeed I have no idea how criminal law addresses something like this.
If I make a copy of your [valuable] personal data against your will, is that not a criminal offense? If I do so in a way that destroys the value of the copy you retain, is that also not a criminal offense?
Earlier this year, slashdot featured an article about how IBM is dumping "a billion dollars and thousands of researchers" into a new Watson group based out of New York City.
Now, less than two months later, they're axing half of their New York work force? And their explanation is that they're shuffling their investments into new areas of technology, such as cognitive computing? Isn't that what Watson is?
I don't know where you live, but here in New Jersey, it's illegal to steal both $1 and a double cheeseburger from the McDonalds Dollar Menu. There is no distinction made on the basis that the cheeseburger is not legal tender. It's theft either way.
You are free to import any CPAN module, but no utilities of your own written specifically for this purpose.
That's not exactly a fair comparison. It's not like Wolfram is working with a vanilla Mathematica. He got to personally write lots of additionally helper functions specifically to put on this demo.
You'd be more reasonable to demand that GP write a single perl module that duplicates all the functionality that Wolfram has added to Mathematica. While this would no doubt be a lot of work, I see no inherent shortcomings in perl that would prevent this from being possible.
From what I've seen (i.e. the slashdot summary and comments), there's really nothing novel about this Wolfram Language, beyond its comprehensive set of helper functions, which could be implemented just as easily (more or less) in any other flexible language.
Now, perhaps microgravity does weird things, but my understanding is that the surface tension of water would cause beads of water to form spherical blobs. Any blobs that touch would generally combine to form larger spherical blobs, and so on.
I didn't suggest blowing them out of the way. I suggested sucking them into the mouth, and then swallowing them. Presumably, if they're near the nose, exhaling through the nose would push them towards the mouth. If they're not near the nose or the mouth, then they're not a threat to breathing.
I wouldn't expect water to create a film over any surface, as that would not maximize the ratio of volume to surface area (which is what surface tension accomplishes). I similarly wouldn't expect the water to exist as a fine mist or any other collection of small blobs, since surface tension causes water to "stick" to itself, resulting in the merging of any smaller blobs.
Then again, I've never played with water in microgravity. Considering launching a kickstarter where you can fund my flight aboard the Vomit Comet, where I will attempt to drink blobs of free-floating water in microgravity while I wear a bikini and show off my moobs ala Kate Upton. Any takers?
I guess if you had plain gold coins, it wouldn't be theft either? It's not like plain gold coins are a "real" currency either.
Thanks for the heads up. I'll be traveling to Japan in about a month. I've heard about how they have very low crime, but it is now clear to me that this is only the case because stealing isn't criminalized.
Everyone is trying to portray her as "someone randomly.. taking pictures" of the bar patrons. It's clear that she wasn't taking anyone's pictures, and only moved to activate the camera when personally threatened, specifically to have evidence of her own assault (not out of spite). Of course, I wouldn't expect the aggressor(s) to respond kindly to this, as most people who are engaged in the commission of a crime are generally not keen on others possessing evidence of their criminal activity. However, that doesn't somehow shift the blame to the victim here. Are you suggesting that criminals should have the right to destroy evidence (or otherwise prevent the collection of evidence) of their crimes?
Mr. Pearson's calculations show the total infrastructure mass below 1e6 kg, or about 1000 tons. The climbers are another 5e5 kg, or about 50 tons.
For comparison, the ISS has a mass of 2e4 kg, or about 20 tons.
With the assumed cost of $5m per ton launched to LEO, that's only about $10B to get this thing launched. According to Forbes, there are at least 100 individuals that could each fund this with their own personal fortunes. Carlos Slim could fund the launch of seven of these himself. Of course, actual launch costs could be much lower. Currently, SpaceX's Falcon 9 v1.1 only costs about $3.7m per ton to LEO. If their VTVL Grasshopper performs well, launch costs would be further reduced.
Additionally, I'd like to point out that the lunar space elevator is not going to provide low cost access to space. It serves a different purpose. Even if you have space elevators on both Earth and the moon, lunar materials would still be much cheaper to deliver to space. The moon has only 1/6th the gravity, which makes it that much cheaper to lift things off of it. Additionally, the lack of lunar atmosphere decreases losses inherent to the climbers (power delivery, drag, etc.). In LEO, moon rocks will still be cheaper than Earth rocks.
Also, when undertaking a project this ambitious, a lunar elevator as a first attempt makes much more sense. First, it's much easier. There's no atmosphere, no weather, no magnetic fields, no security concerns. Additionally, the gravity is considerably weaker, meaning we could do this today (or even 30 years ago) without any advances in materials science.
So then when this woman said she would start recording (she hadn't been previously) because she felt threatened, the aggressor(s) backed down, because they understood that it was just for liability reasons, to protect the Google Glass owner in question. Right?... Right?
Ahh, but say the ballast asteroid cut loose, or the cable was severed above the center of mass, the remainder of the cable would still be attached to the earth.
Okay, I'm with you so far...
The rotation of the earth would impart some lateral velocity to what was left.
The Earth has been rotating for some time. Presumably, prior to the "cutting loose", the tether would have been connected to the Earth. Any way I look at it, the rotation of the Earth would have been imparting some lateral velocity to the elevator from the moment it was first erected. Also, "lateral" velocity? Is your frame of reference rotating with the Earth, or are you a member of the Flat Earth Society?
The end of the cable would immediately begin to accelerate and would either burn up in the atmosphere (which shouldn't happen at the strengths of materials needed to build such a cable) or hit the ground at hyper velocity speeds devastating anything within kilometers around the line of impact.
Due to the Earth's rotation (and the ballast's orbit around the Earth), the cable would have been accelerating from the moment it was first erected. That's the whole idea behind a space elevator. That's why the elevator doesn't just go flying off into space in a straight line. Acceleration keeps it in orbit around the Earth, much like any other type of satellite. When the tether is severed, the "upper" part flies off into space, and the "lower" part falls to Earth. This happens regardless of where exactly the tether is severed. The only difference that makes is how much flies off into space, and how much falls to Earth. Nothing will hit the ground or even travel at "hyper velocity speeds" due to terminal velocity being rather low for objects with low mass and high surface area (which are inherent properties of any tether that would work on Earth).
On the positive side, we would get a nice line on the equator, kinda like what we have on maps now:)
There would be no line, because there would be no damage. But, even that aside, this would likely be in the middle of an ocean, so the copious amounts of liquid water would probably wash away any line in short order.
Also, all of these safety concerns have been addressed for some time now.

Sure, just like it would be working better still if we just jailed every last man, woman, and child.

Build one on the moon using kevlar.
A lunar space elevator could be built using 1970s technology, with kevlar as the tether fiber.
Funding and a lack of political will.
