This actually makes me curious. Why don't we have photochromic windows? We use the technology in transition lenses.
>At the New York World's Fair of 2014, General Motors' "Futurama" may well display vistas of underground cities complete with light- forced vegetable gardens.

Amazing prediction!

Well, he got the GM part wrong, but indeed, there was a series called "Futurama" and it DID display "vistas of underground cities" (New New York)!
When I went to the nearby Western Beef I was very surprised to see all kinds of sections, and then a Goya section. Over time I learned that I could find things there that I couldn't find for recipes elsewhere. But there wasn't a General Mills section. This article helps explain it.
I had the same experience. After hearing friends rave about mechanical keyboards I ordered a custom one from WASD. Great build quality though custom engravings are less sharp than I expected. It's a lot of fun to click clack away on, but within 2-3 weeks I developed serious wrist pains that I had never experienced before. My typing wasn't any faster, the noise was distracting (even with "quieter" Cherry Brown switches) and it was seriously crowding up my workspace.

I switched back to the wired Apple keyboard and the pain gradually went away. For my posture and setup the ergonomics of a thin keyboard are a lot better. I can see the romantic beauty of mechanical keyboards, but they're not for everyone. If you're able to, borrow one from a friend before splurging... YMMV.
Makes sense, but does it confuse the for profit and non-profit?
Agreed, Nexus 4 was already a great deal, IMO, at $350, $250 is a ridiculous price.

Elisp Intro: book review and solutions
Can anyone recommend a good book for experienced developers to learn java from? I've done work in Obj C, JavaScript and Ruby. I initially had little interest in java but there are a lot of coursera classes that assume familiarity with it.

Basically, I'm looking for a book that doesn't spend chapters telling me what variables, loops and functions are.
>And experimental fusion-power plant or two will already exist in 2014. (Even today, a small but genuine fusion explosion is demonstrated at frequent intervals in the G.E. exhibit at the 1964 fair.)

Atmel has been really good about supporting CPU footprints over many generations (their customers don't like redesigns either), and the FCC rules seem to give you a pass as long as you haven't changed things electrically. There's actually a reasonable amount of wiggle room - basically if there is no reason a board should perform differently, they say it doesn't need to be recertified. (at least, that's what they say)

That said, our goal is to brave the waters of the FCC to provide quality radio products to the open source community. If we succeed in getting funded, we should be able to handle the occasional new testing needed for any product changes.

We have some higher volume plans which will help pay for that. Arduino is only part of what we're doing. :)

This all started because there weren't any open source module designs for the CC1100 radio, so I made one and put it on github (actually I was using the 2.4ghz CC2500 at first). Eventually I slapped an arduino on, and boom, useful thing!
I think the technology is just too expensive unless you want to show off: http://en.wikipedia.org/wiki/Smart_glass
Work in moderation and brainstorm small concrete tasks you can do that will count towards some measure of completion for the project the previous night.

It's a lot easier to get started when you're not staring at a mountain and just have a set to do list. Rinse and repeat each day.If you're working on this only in the evening or something, work on the list from the previous day, stop early before you go to bed and come up with set plans.

This counts for things you have to learn to execute these projects. Try to maximize your time by prioritizing things that could count towards both projects where possible.

Much of your progress or sense of accomplishment will come from completing small milestones, and have a huge impact after you're able to look back on it. The key to this is to keeping the tasks small enough.
yes you absolutely can do this! We will have ultra low power sleep modes, and the radio can turn on briefly to send status, or listen in low power mode for remote communications.

Steel is >$0.60 per kilogram when purchased by the tonne. I believe the GeekDesk frames weigh over 100kg. So that's $60 just for the raw steel before it's been turned into anything useful or adding the motors and electronics.

I invite you to try to just break even selling adjustable 100kg steel desks to end-users at $150 each.
Don't worry, I know this isn't easy, but I don't like easy things, they're boring. My last project involved hand-winding motor coils for a linear motor I built from scratch, along with a 24v 10A per channel driver board & ARM CPU mainboard I designed and built. It was a pretty neat system, but robots are complicated, so I'm going to sell circuit boards for a while and dive into software development some more.
Please. This is actually a common misconception about the Friis equation. It assumes an isotropic antenna with an effective area that is dependent on lambda. But physical antennas have an effective area that varies with lambda squared (obvious on something like a horn or a dish with a real 2-D aperture, but even simpler antennas behave this way). It turns out that this perfectly cancels out the frequency dependent term in the equation when the transmitter and receiver use the same antenna, leaving you with only the reduction in power density as you move away from the transmitter.

I had a professor give an epic lecture about this several years ago, but this is the best I could find on short notice [1].

As it turns out, there is a real source of frequency dependence in your path loss, which is the atmosphere. Your link budget calculation is really just an annoying geometry problem. Conservation of energy still holds, so you should be immediately suspicious when the naively applied Friis equation (which does not take atmospheric effects into account) makes received energy vanish just because you cranked up the frequency. Just as you should be suspicious when you receive more energy than you transmit when you're in the antenna's near field. Always know what your approximations imply.

The receivers are actually a bit more sensitive than that (the TI chip is ~-120 dBm at the target frequency; the whole package could be close to -114 dBm if designed well).

The claim I made was that you can't get half a km on 16 milliwatts. I cited 16 milliwatts because it's the max transmit power of the TI chip alone. You cannot make this go half a km with the antennas shown on the kickstarter page. You'd either need more power, or one of the antennas would need to be a dish. Even in an unreasonably quiet environment, you'd run out of energy at the receiver way before running into frequency or bitrate dependent effects.

But it turns out that 16 milliwatts is not the output power used. TI makes an amplifier that increases the output power to half a watt. In this case you'll easily get the half-km range.

I got really excited at first reading this, someone agreeing with me that keyboards nowadays were not evolving.

And yes good mechanical keyboards matter, but that's not what we should improve them on.

A good keyboard should have : usb 3.0 ports, mic/headphones entries, wheel to control the sound etc...
The word "credulous" comes to mind.
On some of the missing ones:

1. We have at least one fusion plant I know of, the UK Joint Torus, which I know have been operating for decades. It just consumes more power than it generates. But Asimov suggests one or two, which is strikingly accurate.

2. We could probably make radio-decay batteries (maybe not AA size, but car batteries running on Thorium or some such, albeit an extremely expensive containment for something running so hot). We probably just don't do it because the radiation risks are too high.

And I'd count airport conveyors as moving sidewalks. Or just the complexity of baggage carrying systemes in those airports, lend that we easily have the technoloy to create weather resistant rotary motor systems as sidewalks, but like Asimovs suggestions of underground housing, cost is the bigger prohibitor than technology.

Also, I don't think the degree of boredom he touches on has occured. Consumerism and the wealth concentration in the US has kept people needing to maintain 40 hour work weeks where productivity is magnitudes higher. We produce vastly more, but work as much as ever. Back in the 60s the sentiment was that 21st century Americans might have 10 hour work weeks.
In most web browsers, middle click closes tabs, opens links in new tabs, and on Windows, starts an automatic "scroll follows mouse" mode. I seem to remember that at one point, Chromium on Linux would interpret middle clicking on an unclickable part of the page to mean "interpret the text stored in the clipboard as a URL or search term, and go to it." Imagine the fun I had with the occasional misclick of a link before I found an extension that implements Windows-like middle click scroll.

The only time I ever intentionally use middle click paste is when using the terminal where, you know, Ctrl-C and Ctrl-V are already taken. An option to disable middle click paste for everything but terminal emulators could only be a benefit, removing a rare but ever present source of confusion and mistakes.
It would be nice if Google would actually let people who aren't using a US ip address to be able to view the site. I have an account and mailing address in the States, but I live outside of the States. So even though I can buy, they won't let me see it outside of the States.... Way to go Google!
I like your Triforce key :)
Honestly I wish they changed the name. Shopping for a Nexus 7 online or in stores is not friendly to the regular population. I'm pretty sure I know what I'm doing and even I'm not 100% certain a Nexus 7 on any site (besides play.google.com) is the new refresh model or the older one.

That said, they should avoid the naming scheme of the galaxy line (e.g. Samsung Galaxy Tab 2 7.0).
We have a lot of resources for manufacturing in China. I've personally ordered a few thousand assembled boards from Gold Phoenix through the course of my old job, which was... fun.

We've got a lot of connections in Silicon Valley to tap too for finding hardware partners. I'm not particularly interested in becoming a fab house, unless it's cheaper (including headaches).

Thanks for the well wishes!
While I can understand the appeal of mechanical keyboards (at least appeal for you but hatred from your coworkers), I really don't understand why any programmer today is still using a non-ergonomic keyboard. These straight keyboards will kill your wrists, forehands and tendons eventually.

If you intend to be typing on a keyboard for more than the next five years and you're still using a straight keyboard, do yourself a favor and buy a split keyboard today.

Pains from Carpal Tunnel Syndrome will most likely follow you for the rest of your life, just not worth it.

actually not at all, we have less TX power than most wifi devices. The data rate is inversely proportional to range, as is the frequency. We operate at a lower frequency than wifi (915 MHz), and a much lower data rate (your Arduino probably does not need a 100Mbps connection). This gets us range without blasting people with radio or having trouble with the FCC.

It does do useful things on Windows. There are the browser behaviors I mentioned above. Most image editors use middle click to pan, and I think 3D modeling programs use it to rotate and pan as well. It's only in dedicated text boxes that middle click does nothing useful, but we're all so used to Ctrl-C and Ctrl-V that we don't have any desire to use that button for pasting.

My prediction is that data can replace empathy, just as Watson can beat human competitors most of the time. Students struggle with new concepts, but do they all struggle in uniquely different ways? Aren't there patterns? I think the data from millions of interactions, and a curriculum guided by the best teaching minds the world has to offer will be better than the average teacher, up to a certain point. Note that I mean this in a very narrow sense, when constrained to a specific topic, and especially when explaining something intuitively to a student and answering students' questions. I agree though that for the foreseeable future there still need to be teachers.

I'm all for better teachers, but I think it's just not going to happen. They haven't become better in the past few decades or even century, rather possibly the opposite, with the need for many more teachers than there are competent people to fill those positions. The only solution I can see is to make teaching one of the most highly paid and highly respected professions. There doesn't seem to be any incentive for this, and it would require a huge cultural change. And even if that was the case, there would probably be the a concentration of teaching talent in the big cities at top schools, while rural schools will have to do with the scraps. Software at least is democratizing.

Of course what I'm suggesting would require some very sophisticated software that doesn't exist today, but I would say that for me, if I would have followed the videos on Khan Academy (for science and math) instead of the education I received, I would probably have been better off. I grew up in a rural area, and I know how bad it can be. After getting an engineering degree, I now see how little those "teachers" actually knew or understood. It's shocking really. But I'm not surprised when you look at the kind of people that go into teaching today.
Is it really preferable, hardware-wise, to something like the HTC One?

>I use the Kinesis Advantage and built a little wedge out of wood to stand it on so that the keyboard is pitched in the opposite direction than most.
