We need a topic on RCs.

Now, I've tried my hand at RC fixed wing with mixed results. It's REALLY hard to over come the instincts and comfort honed over couple thousand hours I have behind the flight yoke. It's honestly easier to fly the real thing. Still:

I just got myself a Syma S107. http://syma107.com/

But I already have a problem. The top blades aren't spinning properly. I'm guessing it's the main shaft, because when I turn it on, and give it throttle, all the gears work, but when I turn it off and rotate the blades manually the lower blade gears move but the top ones don't.

Actually, it was a quick fix. When I tried to lightly pull out the inner shaft the top just slipped off, like it was 2 different pieces, when it's sold as one piece, so I super glued it and now it works fine. Look at this little beauty fly.

After seeing a scratchbuilt remote control hovercraft in a hobby magazine in a library one day, I have decided that one of my life goals is to build a working scale model of a Svantovit IFV. In scale with one of those 28mm elemental models preferably.

>By using optical equipment in a totally unexpected way, MIT researchers have created an imaging system that makes light look slow

>MIT researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That’s fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle’s bottom.

>Media Lab postdoc Andreas Velten, one of the system’s developers, calls it the “ultimate” in slow motion: “There’s nothing in the universe that looks fast to this camera,” he says.

>The system relies on a recent technology called a streak camera, deployed in a totally unexpected way. The aperture of the streak camera is a narrow slit. Particles of light — photons — enter the camera through the slit and pass through an electric field that deflects them in a direction perpendicular to the slit. Because the electric field is changing very rapidly, it deflects late-arriving photons more than it does early-arriving ones.

>The image produced by the camera is thus two-dimensional, but only one of the dimensions — the one corresponding to the direction of the slit — is spatial. The other dimension, corresponding to the degree of deflection, is time. The image thus represents the time of arrival of photons passing through a one-dimensional slice of space.

I saw a TED speech about essentially today you have no excuse to not be able to program- we should be teaching it to kids so that use computers as a tool, not a video game console to the interwebs, and that programming is something that all computer users should be able to do, and I agree.

So I'm trying to learn to program. The most practical I can think of is Java, for making actual programs, and having taken a little bit of programming in the past it looks the most familiar to me, plus you can get a working GUI virtually right away. Is Java a good language to start with? I know people will say "C++, faggot" but I tried reading a book about that and it looks a bit... overwhelming. I'd go with python but that looks a bit TOO easy.

what was YOUR first language? how many do you know now and do you think your first language contributed to how easy it was to learn more than one? Do you actually program for a living? What'd you recommended to do, first off?

I should come to /tek/ more often. I had no idea this thread was here.

4th year in the computer science major, still feels like I'm making shit up as I go along while waving my hands. I'm not sure if that's how I'm supposed to feel though.

>This makes a lot of sense to me. But learning about computer hardware seems like it would be more difficult than learning a programming language

Speaking from my limited experience, which just amounts to a couple of classes, it's not particularly too difficult. I mean, unless you're talking about the engineering perspective. But when you get into stuff like caching, pipe-lining and all that jazz it's not too bad. I mean I had a much easier time understanding that than grasping things like dynamic programming.

But really programming languages are kind of in a similar situation considering you can solve a lot of problems without actually going too in-depth of an understanding of the language. But then again there are people who could go to graduate school and spend years trying to learn the ins-and-outs of a language and still not completely understand it all.

It think it was the BASIC variant that was used in "Learn to Program Basic", though I might have tried out batch files a bit first.
Not sure I know any that well, I know some BASIC, ANSI C, the fact that I do not want to use Java ever, Flash, and now some Lua.
No I do not.
I think a QBasic variant might be good, but so far Lua is nice. Very C-like, but to me it seems a bit easier. Though now that I think of it, I might be able to go back and do better at C, I'm not sure. I ran into a brick wall trying to work with the filesystem the last time I tried C, but it went pretty smoothly in Lua despite the complete I/O model being so similarly to that of C. I think a part of it is that I'm not searching though a pile of libraries for the most simple of tasks. The Programming in Lua Guide has been very useful, at any rate.

Dedicated video cards for laptops look like this, right?

I always see advertised that those cards have x amount of DDRwhatever memory at XXX MHZ and with a XXX bit bus and so on. Uh, but exactly where is the memory? I only see a GPU there. Perhaps I am making a fool of myself here, but if it says "Dedicated" then I wouldn't expect it to take it from the system memory (is it?).

There's memory allocated elsewhere (near the chip), usually.

Relevant because of the engineering challenge that must have been. Not building the instruments so much, but figuring out how far apart to place things based on the speed of the car, what gizmos to use to hit them, etc. (The big noisy tunnel seems like it might be using the same footage for all three play-throughs, though.)

Using my tax refund windfall, I've purchased a Performance MX Laser mouse. My MX1000, which I've had since it was first released (five...six years?) finally became too much of a hassle--the middle thumb button (which I use for push-to-talk) only responded half the time, the wheel was loose as hell, and I was starting to get response issues. Still works great for generic-use mouse, though.

Only thing I don't like about the MX is the scroll wheel. No horizontal scroll, and the wheel is intentionally loose. Though oddly, the continual spin is somewhat satisfying.

Gotta get used to these different button positions. Also what to use the extra buttons for in TF2...

>Scientists have linked two diamonds in a mysterious process called entanglement that is normally only seen on the quantum scale.

>Entanglement is so weird that Einstein dubbed it "spooky action at a distance." It's a strange effect where one object gets connected to another so that even if they are separated by large distances, an action performed on one will affect the other. Entanglement usually occurs with subatomic particles, and was predicted by the theory of quantum mechanics, which governs the realm of the very small.

>Another study recently used quantum entanglement to teleport bits of light from one place to another. And other researchers have succeeded in entangling macroscopic objects before, but they have generally been under special circumstances, prepared in special ways, and cooled to cryogenic temperatures. In the new achievement, the diamonds were large and not prepared in any special way, the researchers said.

>"It's big enough you can see it," Walmsley told LiveScience of the diamonds."They're sitting on the table, out in plain view. The laboratory isn't particularly cold or particularly hot, it's just your everyday room."

>The two diamonds, it seemed, were so connected they reacted as a single entity, rather than two individual objects.

Sort of. Peer review and publication works sorta differently for math and physics. ArXiv is a sort of pre-publication open peer review platform that most/all math and physics papers get put on. It wasn't just that they thought their results were weird, that's just the thing that's done.

I love quantum mechanics. It's the closest thing to magic that we have left in the world.

Hell, if you could master the nature of the connection between two objects and synthesize/independently generate that relationship somehow, you could do all sorts of incredible/awful shit.

Don't think so. The encoders you named are used through front end programs that streamline the process for the average user. Looks like the MKVTools website has some new aps dealing with MP4 stuff. Hardsubbing you'll have to ask someone who knows more.

Lately I have been havign trouble with my internet speeds. I can't explain to you how bad they are, all I can say is that the LoL patch took 20 minutes to patch and had trouble getting above 100 kb/s. Now I don't know if it is because i play alot of LoL or if it's because of something else. All i do is torrent animes (300is mb/s) one three days a week and LoL. Any ideas on what is causing this?

Is there anyone else using your internet? If so, that could be the problem but if it was only the LoL patch that took so long, you possibly downloaded it with thousands of other people at the same time and 100kb/s was all it could handle.

I'm still using 10.04 and don't have any problems with it, so I don't plan to change as long as it's supported.
