>Wouldn't there be a force in the direction you are accelerating in?

Well, yes, that would be the standard way to look at it. Sorry for being confusing.

>Anyway, when you accelerate a car, you are not feeling acceleration, you are feeling the force of the car on you.

According to [Force = Mass * Acceleration] you can take them as equal (apart from the constant factor of your mass). In the freefalling box that is accelerating (and thus no longer in free fall) you'd also feel a force. No need for experiments if you have your normal senses. You'll be pressed against one side of the box. (And if the acceleration is 9.81 m/s^2 you couldn't distinguish it from a box on earth.)

That is actually the basic premise of general relativity - the equality of 'inertial mass' that resists against acceleration and 'gravitational mass' that happens because of, well, gravity.
It's like the idea of constant speed of light for special relativity.

edit:
Unless you're talking about gravity, which accelerates all parts of the setup equally, thus no force results.. but that would need something else in the experiment, either a great amount of matter or energy. But then you'd have a reference frame right there. (Mathematically. As for an experiment.. hm. Check for perturbances from space-time distortions that result from rotating gravity sources, maybe.. most gravity sources in this universe are rotating. There's an experiment done that checked that for Earth.[1])

But the funniest jokes from these cards aren't from potty language, but from the following:

We had about 10 players, I read the card. _____. High five bro. Players played what they thought was funny. One person put down the card, "Battlefield amputation"

I read it, deadpan. "Battlefield amputation. High five bro.".... And in the course of 5 seconds, we all just realized how wrong that was. One lady laughed for a good 5 minutes for that card response.

This is kind of a crude definition. If you knew a certain slot machine in Vegas had a positive expected payout, sure, you'd be rich, but is it an investment? Also, there are plenty of people legitimately investing in companies that have less than even odds of a return.

Investing to me is more about mindset and the manner in which you deploy capital for a return, and how much you are relying upon luck, guesswork, and chance.
Wow- That is great. Thanks for sharing!
I really enjoy signing up for classes out of curiosity, trying them out, and then dropping the ones that are a poor fit or that I don't have time for.

Being able to do this has been liberating and I suspect many do this.

I dropped one class because I was unimpressed with the professor, although I still want to take the subject.

There are many subjects that I have an interest in, and I might sign up for, but with a low enough threshold of interest I might be inclined to drop unless it is a pretty good class.

In the end I suspect it will help the teachers improve their game, especially if there enough classes that there starts to be some competition.

Again that's what I thought too. But it was coming from different friends. Which means all of them must have done the same thing.

Soo... this is another part of my problem, is that in public venues like HN or Twitter you guys boss up getting people to your support site.

However, once on the support site, it falls flat on its face. I am pushed off to one person who doesn't care after another, who doesn't listen or read. I've called 'em out before and that's how I usually get escalated to Mark...

They've got tickets to answer, they're busy, but it's blatantly obvious most of your CS reps goals are not to fix my problem but to get through tickets.

I've done high-end technical support, and I know that people 'believe' in it while they're in the office, talking the talk, but not in their actions. That's your problem, culturally, and publicly, you all say it so many times people believe they're doing it without actually know what it means.

From the outside: you're failing.

Furthermore: I hate being passed off to an account manager cough sales rep cough who kisses my ass when I don't have problems then can't do shit to help me when I do. I don't want a reach around, I want my problems solved. Phone support? A joke. Within 30 seconds of the person on the phone realizing the problem is actually technical, they push you back to the support site.

You guys should signup for a Linode account, file a ticket, and learn from that experience. It's baffling that Linode doesn't boast about its support, like you all, but manages to consistently provide better support resolving my issues quickly without a terrible back and forth.

It's only obvious because that's what you were taught. Aristotle thought that a moving body would come to a halt by itself, unless you keep pushing it. He thought that this was a law of physics. This didn't require any aether or other substance. It was almost 2000 years later that Galilei came with the idea bodies set in motion will remain in motion, and that the fact that they usually stop was solely the result of friction. But even then it is not clear that there isn't some other method by which you can find out your absolute velocity. It was only in 1887 that the Michelson-Morley experiment showed that you can't do that with light! So this is not a triviality that can be deduced by logical reasoning, it's an experimental result of physics.

This makes you wonder which falsehoods we currently take for granted, that later generations can't even fathom anymore.
Every time I see a Java article I think to myself how Java is so far behind C#. I feel like MS took all of the things that make Java great and made it way better and all of the Java fan boys either can't comprehend that or choose not to.

The videos there are misleading. The level of quality shown is nowhere near what that hardware can achieve. For example, in the "video from the lab", virtual objects are shown occluding someone's hands. That is not possible with the display technology they're using. Your real experience with the device will not be anything like the videos shown. The display will be more like a ghostly, low resolution overlay, with significant latency.

The sad thing is that the hardware actually looks pretty neat. This device should be cool enough that a realistic demo could easily sell it without misleading people. I hope Kickstarter starts cracking down on projects using pie-in-the-sky concept videos to raise expectations that they can't possibly deliver on.

Ask HN: how strong is your focus when you are coding?
It seems to me that the stronger my focus, the more productive I am when coding.

However it is very hard to remain tightly focused. So my programming productivity swings wildly as does my focus. I am trying to become more productive when I code, so I'm trying to train myself to remain focused for longer.

I'm interested to hear the thoughts of other people. How strong is your focus when coding? Do you get long stretches of focus and productivity? Or do you keep losing focus and having to work to bring it back?

Also, how old are you? I'm interested to know if it's easier to focus on coding when you are younger. I'm 45.

They seem to be focused on providing features 99% of Linux users don't want or need instead of fixing the plethora of bugs that are creeping in. Last time I tried to install Ubuntu, I ran into several bugs in the installer, which Linux Mint inherited. The hard disk encryption setup failed, for example. When I finally got the installer to work, I was greeted with several background apps crashing. Months later, these bugs still aren't fixed. The quality has really gone down in the last 2 years, to the point where I'm thinking I'll have to give Debian or Fedora Core a shot next time.

I wish these people would focus on being more minimal: do one thing and do it well. Instead, they've been trying to tailor their desktop OS to run on tablets. Who the f* runs Ubuntu on a tablet anyways? (if you do, please respond) They're alienating most of their users for a potential market they realistically have almost no chance of getting into.

Hey, You're right, $100k is nowhere near enough to build all the supporting technology. Our software development is covered by investment, including YC. The Kickstarter is purely about covering hardware costs and the $100k threshold is for minium production runs.

Filming stereoscopic video through the glasses is very complicated which is why we used concept visualisation to give an idea how it will feel. We're working on a rig to film through the glasses, but right now there's no way we'll be able to convey how impressive it is in person through live video.
The article made me think about home schooling. Some home schooling is done for religious reasons, but other home school is motivated by academic concerns. There is not so much of the second kind because it raises an awkward question: how is the parent to do better than school at teaching a subject about which they themselves are ignorant?

Enter the MOOC. The content is available, at a level and pace to suit a child. The stay-at-home parent can learn along, providing the child with both guidance and flesh-and-blood encouragement on learning and learning to learn.

I anticipate that MOOC will change the balance in home schooling with a big expansion of the academically motivated aspects.

They talk about how under "Scalability" how "Java did not seem to fit the project requirements"... I'm sure a Java implementation can be less scalable than a node.js implementation, but every anecdotal piece of evidence I have experienced suggests that a good Java implementation will be faster than a good node.js implementation.

If we look to popular micro-benchmarks, they support my anecdotal observation:

http://benchmarksgame.alioth.debian.org/u64/benchmark.php?te...

http://www.techempower.com/benchmarks/

On a side node: node.js also suffers from the issue that while a small node.js program might be fast, what is actually fast is the C code and as the program grows larger and increasing amounts of time are spent executing actual javascript its performance characteristics change dramatically. This fact seems often lead to unrealistic understanding of node.js performance due to people benchmarking very small examples.
Gawker shouldn't be asking the public to fund their existing enterprise. If they have $200k, they should pony up, because obviously they think it's worth that much.

"The way to make money off a standard is to sell it's complements"

That seems to be how things went. Tantlinger created over 70 patents related to transportation in his lifetime. Sea-Land, his employer, sold containerized shipping services.

I doubt there were any regrets about dropping the patent. Malcom McLean, owner of Sea-Land, did pretty well for himself:

[R.J.] Reynolds agreed in January 1969 to buy Sea-Land for $530 million in cash and stock. McLean made $160 million personally and got a seat on the company’s board.

Yes, but the kinect camera isn't moving around a space. That's what I'm talking about. Figuring out the camera's position in an unknown environment using a depth camera is much more difficult than figuring out the position of objects moving through a static space with a depth camera.

I meant predictably to someone with knowledge, but not to someone who was ignorant.

For instance in some cultures if you say "wow, that is a nice object in your house", the host is almost obligated to give it to you as a gift. In others, as a guest, you're expected to say something nice about someone's taste even if you don't actually like it. In ignorance, you can end up either jacking a bunch of crap you don't want (thus leaving someone deprived of his property as well as needing to find a way to dispose of some useless things), or viewed as haughty and rude, depending.

With women and conferences, one thing I learned was that completely qualified women do often tend to underestimate and undercommunicate their credentials, vs. men, similar to some foreign cultures. Knowing this is useful.

Bucket List: Things To Do Before You Die
The article was about the How more than the Why (ie. "How We Built eBay's First Node.JS Application). It would be interesting to know more about the pro/con debates, but it did a pretty good job of providing high level detail on their development stack. With new technologies people often ask 'what large production environments has this been used in?' Articles like this help to answer that. And since there are so many modules and options for node developers, articles that highlight some of the more popular and mature modules can really help narrow the field for people who are wondering where to start. By the way TechEmpower has some great comparisons of performance metrics that are probably targeted more to readers like yourself who want detailed comparisons and analysis of technologies under particular use cases.

I find myself disagreeing still. I would say that the idea that you can't measure your own motion without something else to measure against, is obvious to the casual person. (Whether that "something" is a physical object, the background radiation, the luminiferous aether, or whatever.) The possibility that it might not be true is actually far less intuitive, since it would require there to be some intrinstic frame of reference that is impossible to leave behind, even in a thought experiment.
You're right. I misread your post and didn't realize they demo hands being 100% occluded by virtual objects. Can't believe they're that brazen.
