At my workplace, we obtained a Tobii Rex for dev and investigation.

After both my supervisor and I took a good long crack at it, we could think of very few ways it could be used. Of course, eye tracking has traditionally been used in the medical disabled industry, for good reason.

But when it comes to "What can it be used for in a university setting", we came up with a blank.

rdw is correct about the eyeX, and it also applies to the Rex: the operational area is around 2 foot cube. If you move your eyes out of that, the driver/SDK throws a tantrum and desyncs your gaze. This also means having an interactive demo is nigh impossible, as the gaze tracker has to be within a small area of the head/eyes.

And you better not blink, as it cannot track an eye. It has to have both eyes available. Im not entirely sure why they didn't implement tracking with each eye independently, but that's what they did.

Calibration is also a pain. You have to calibrate the device stick to the monitor (not hard), and then you have to follow your gaze around the screen to the little dots for calibration. With this calibration, it changed significantly from morning to evening to the point I had to be a different user.

I also found their SDK and accompanying demo software to be completely lackluster. Every demo required keyboard button presses. Not only that, but their program in the control panel had no hands-free options; just mostly hands free. There was no completely hands-free app to control parts or the whole computer. This is one of the reasons we thought this might be interesting.

The other issue is of accuracy: what the hardware is doing is sending out tons of 'gaze detection events' that raytrace where the device thinks you're looking. When you're in the calibration, you can see this by the dozens of dots around the 'focus dot'. These are the ray-traces that attempt to figure out your gaze. And it's not great. Some dots in the middle (think + on the screen) were fine. But the dots on the 4 corners of the screen would routinely come in as scattered clouds that would "kind of, not really" synchronize. And we'd have to go back through the calibration because accuracy really stunk.

In the end, our dept gave our Tobii Rex to the Disability office of the Chancellor. We both hoped they could tease out better performance and usability than we could.
Hm.. as hardware becomes a commodity, I don't think that custom designs can beat the commodity price point. What would be helpful, more web/interactive kind of tools to make hardware better accessible. For example, simple power calculators, that would compare the power consumption of an Arduino with special low-power devices. Or, how a 5V system compares to a 3V or 1.2V.
Why isn't there any mention of Sencha in these lists ever?

IMHO they are a very mature Javascript front-end MVC framework. Sencha ExtJs is now almost 8 years old and Sencha Touch is over a couple of years old at least.
Quite a lot of the history has been written from the stories carried down, and I do believe the central and south american tribes had writing which is still largely ignored.

(Edit: quite a lot of the old stories are written down, downvoters- I cannot help if you don't value the current efforts. I won't be providing links as there is Google and I have to deal with a damn blizzard)
My experience so far is that writing code that defeats tree shaking is somewhat more difficult when adopting the simple functional style of the Closure Library base libs. Fortunately for ClojureScript, this style is already idiomatic.
Yes, although chances are you'd need quite a lot of hardware depending on the scale of their network. Doing so would also be illegal, of course.

The Danger of Calling Uber a “Tech Company”
A biology student told me that Cancer cells are "running" in a partial state and don't require the same amount of nutrients that normally functioning cells do, therefore if you stop feeding cells altogether, the healthy ones will die first.
Not at all. Nor am I "fine with" what happened to the natives.

All I'm asking is, would it be any major abberration, considering human history? Or would it just be: after atrocious violence and savagery, land briefly under the control of vague human entity X now seems to be under the control of vague human entity Y, episode #37,093,840?

Developing an ultra low power design is not a trivial task. It is here where you discover the manufacturer datasheet somehow achieves figures you just for the live of you cannot achieve, even with their reference designs and evaluation kits.

You can spend an entire month just adjusting the state of the various pins on your device to shave off uA's, and just when you have hit your power consumption target, you realise your product now doesn't always boot up or suffers from latch up in some circumstances / temperatures.

Also this article does not take into consideration that the little CR2032 has internal leakage, your circuit has leakage currents and when transmitting you are suddenly pulling a lot more current out of the battery, so it wouldn't deliver that full 230mAh (but he did say it is hypothetical). Getting even 2 years of operation out of any of the CR range of batteries is already a feat.

-edit typo
From the abstract posted by Junto, it looks like the idea isn't to starve the cancer cells, it's to starve the healthy cells. The point being that when starving, healthy cells stop growing and become less susceptible to chemo drugs, while the cancer cells ignore the starvation and keep growing, so do not get the same protection.

Imagine a TV scene where the hero starts yelling 'get down' in a crowded area before a gunfight breaks out. The 'bad guys' stay upright and the confused civilians duck, so fewer civilians get shot.

(I'm not commenting on the actual article's contents, as I think we agree on the value of it).

I think it is useful to use development-related terms when discussing non-development processes and concepts. Analogies are a great way to communicate subject matter that the audience may not be familiar with, especially when that intended audience is a narrow band (e.g., developers).

My girlfriend is a flutist (or, flautist for European readers), and oftentimes, when we're discussing something like octatonic scales, it helps for me to think of these concepts in a way that I feel comfortable (set theory).

Shame nobody actually does this though. Also, does opting out actually stop the data grabbing, or just hide those results?

As seemingly facetious as this answer sounds, it's absolutely bang-on.

Special sauce was the order of the day. Because reasons. :-)
"Of this self-identified population, only a fraction are visible minorities, subject to the discrimination that shapes identity and forges political movements."

Yeah, right. I think the author did very little research into the modern problems. Also, self-identified might cut it for the news media, but each tribe has a list of enrolled members. If you are not on someones list, you are not Native American for a vast majority of purposes.
Another thing to consider is how it looks. Hotel patron sees hotel's free wifi (why should they care that it's not the real thing), but everytime they try to connect, the connection fails. "Man, this hotel wifi sucks, full signal but I can't connect!"

On the other hand, you're also saying that people shouldn't care as much about security if they are on the proper wifi network, which is a little ludicrous. Just hope on a vpn either way, and you're safe.
The economics all depends on volumes, of course.
Well, I wouldn't have installed Android L if I knew how it was going to (1) slow my tablet down, (2) have problems with WiFi, and (3) look awful.

There's a reason why they ran ads for the Nexus devices last month that only showed the devices turned off.
You want a company to omnisciently select from billions of webpages the most appropriate result for you.

You refuse to tell them anything about yourself.

That's not having your privacy invaded, that's wanting to have your cake and eat it too.
A slightly more charitable argument would be that people do care, but are currently under too much financial and day-to-day stress to simply drop everything and participate meaningfully in lots of political causes.

And in this particular case, there are ancillary issues too. The Aaron Swartz case doesn't immediately sound important to non-hackers, and there are no shortage of people who will helpfully point out, over and over and over again, that, "Aaron actually did break the law, and if he didn't want to go to jail, he shouldn't've broken the law, and he had a mental illness besides so the outcome is nobody's fault but his own." I disagree with those people, but they're still able to move the discussion away from where it should be: federal prosecutors acted absurdly.

Gay rights have only recently made serious political progress, obnoxious drug enforcement is being fought against, people are talking about the NSA in light of Snowden's leaks (and, fortunately, the law-worshippers' "Snowden is a traitor and a coward" position didn't stick).

People aren't totally inactive. They're just broke and stressed-out and overwhelmed by a relentless tide of political issues.
I had a somewhat similar experience with EyeTribe, their main competitor (bigger area, lower accuracy, not sure about single eye tracking.)

One use-case I did see however was 'focus follows gaze' which seams at least could be fairly valuable. If I wasn't on OS X (where the windowing system doesn't allow for that) I'd love to have given that a try...
The author seems to have linked to the wrong book as the inspiration for the movie though the author's name is correct.

Thanks for the detailed comment.

The market economics part is interesting to me. I touched on it in the Q&A at the end of the talk. Initially I wanted to have ships trading to make up for deficiencies in their homeworlds (agriculture, raw materials), which would also help generate revenue, and lead to conflict. However it's not so simple (hey! let's build a functioning commodities market and HFT/algo trading system). The seed of this idea came from Traveller[1]. It's worth checking out the trade system in the first edition of that game.

The original planet sim was much more complex (along the lines of World3 [2]) and explored finite resources, overpopulation, technology growth and a whole lot more, but again, for the talk that would have been overkill. I think it's worth exploring this angle as it would provide a whole different dynamic, and would be great to see at huge scale (1000's of systems or larger) and playing out at a slower pace.

Also from Traveller, the idea that information cannot move faster than the speed of light, so it has to move at the speed of transport, which creates great dynamics for trade, and the command & control aspect of warfare. Centralized governments are not so effective. A treaty could be signed, but fighting forces will not know until the knowledge reaches them. A war can start and end before the seat of power even knows it had started.

There are so many things that could go in to it. Basically the presentation is a simple version of what I'd like it to be, but I stripped it back to the essentials (spaceships and lasers!) to make the talk interesting.

PlanetQuest – The Search for Another Earth
Good lord, yes. Have you ever browsed the web on mobile without AdBlock? It's nearly useless. Setting aside the bandwidth you're wasting, nearly every page redirects you to the app store or pops up a dozen shitty ads before you can see the content.

I'm still baffled that ad networks allow advertisers to inject arbitrary javascript into their banner ads. Why on earth are they allowed to deliver anything other than an image?

Anyways, I'll never browse the web without AdBlock again and I'm astounded that so many people are able to do so.
WIMP dark matter search is nearing the end. Race for more sensitive detector can't go on much more, because there is a fundamental limit: neutrino wall. No one knows how to eliminate noise from neutrino, and now detectors are nearing sensitivity enough to detect neutrino from the Sun. Since neutrino from the Sun is the noise floor that can't be eliminated, below that even if there is a signal we can't find it.

Can you give some more details on your nicotine delivery method, I'm trying to quit smoking this year ( actually today is day No. 8 since I haven't put nicotine in my blood ) but I'm super interested in the side effects.

>I'm actually trying out an intermittent fasting diet right now for weight loss. I'm just always skeptical of new fad diets when they start claiming all sorts of health benefits beyond weight loss.

Weightloss. To me, still means in < out. I tried everything (keto, atkins, low carb, high carb, paleo) and intermittent fasting just seems to work for me.

I fast (skip breakfast/lunch and drink coffee) and start eating when I get back home out of work. I love it because I build up a 'caloric buffer', for when something unexpected happens (random cake/donuts/birthday). IF allows me to adjust my calories at the end of the day as I see fit.
Actually, 200 guests on a 100MBit connection is probably not a problem. At a nearby university they have a 100MBit connection for 1000 students plus teachers, and it holds up reasonably well. (Of course, unless the hotel bought an overbooked connection with only a theoretical max speed of 100mbit)

I can't quickly find the all-time most popular petition on the site, but I'd wager it's well under 1 million signatures, which is probably at least partly due to how quickly the uselessness of the petitions site became obvious.
Unfortunately, your story probably isn't all that uncommon. These stories tend not to make the front page of any news/blog sites, though.

I really hope this serves as a wake up call to others with your mindset. Your story hopefully will help others make corrections earlier than you did.

Thanks for the story.
On one hand I find it kind of useful for Google to figure out what I mean for me. Sometimes I just struggle to put what I'm looking for into words so I'll just give it a few keywords and it generally finds what I want. On the other, sometimes it's just frustrating. I made the switch to DuckDuckGo last month, but I still find myself slapping a "!ge" at the end of a query because DDG isn't cutting it.
OpenSMILE: Open-Source Large-Scale Multimedia Feature Extractor

right, and volumens again depend on joining the right hardware platforms/alliances, at least for current semiconductor companies.
I don't think that a few sentences can do a complicated topic justice, but it would folly to point out what you are saying without also acknowledging that Europeans are indeed the people that brought that specific form of slavery to Native Americans. No Europeans, no Native American ownership of Africans, but I agree that a holistic view of Native American culture should be presented in textbooks, etc.
Why not design your own integrated circuit? Now you too can have the thrill of extra capital and technical risk in your project! It has the added benefits of setting your architecture in stone and preventing any kind of pivot while hindering future expansion.

Seriously, you need a good reason to believe you can do better than the chip companies before designing your own ASIC as a commercial project. Low power is not the right end to do this at. The interesting case is when you need moderate computing power for a special task at better compute/watt than general purpose hardware. That's what provoked the wave of bitcoin miner startups.
The title of the article is poorly worded, and doesn't match the thesis of the article. In the end the conclusion is that we do need real time tracking (if only to make investigation quicker, not prevent disasters), but cost and bandwidth make it impractical at the moment.
Maybe something that surveyed if the employees thought the meeting was productive/useful. If my work started to poll my happiness I would take that as a sign to start looking for a new place.

I also think that employees would not answer honestly either. Around my office when the bossman asks how everyone is doing, everyone says "great" even though 10 minutes ago when he wasn't there they were all complaining about one thing or another.
I think them becoming the default on iOS devices will help a lot. I know a lot of people don't know/care the difference between DDG and Google, but those that do will take notice. And maybe a few of them will make that their default on their desktop. What they really need to do is get something going with Mozilla to become the default on Firefox. Philosophically, Mozilla and DuckDuckGo are a match made in heaven, so I'm bummed this hasn't happened yet. I'd imagine it's a money issues because I seem to recall that Google was basically funding Firefox by being the default. Yahoo must have matched or exceeded that to become the default.

The Great Coding School Rollup of 2015
Exactly, it's all about "in < out". But it's the psychology that has me trying the intermittent approach. I don't eat excessively normally, so any weight gain I have is due to being 100-200 calories over on a vaguely consistent basis, which leads to weight gain in the long term.

I figure I can stick to a diet better when it's only 1 day in 4 when I have to cut calories. Whereas if I was any good at cutting a moderate amount of calories every day, I probably wouldn't need to be dieting in the first place! ;)
