The comparison is strained because blood sugar devices are specifically marketed to diabetics. I see that most sleep aid devices are marketed to the general population -- the messaging isn't "are you having trouble sleeping?" it's "Do you want to be a more effective person? Track your sleep!"
Glass was the "one more thing..." moment for sure; heard that there was a long line to purchase them for $1500 per -- any comments from HN owners?

Met with GOOG employees today who were testing newer versions, better resolution & new comms. I wasn't allowed to wear it but it looks bulkier than I imagined.

The odd thing is, during a meeting with an employee who was wearing Glass, it was hard to figure out where to focus my eyes on their face -- it was like talking to someone with a lazy eye.
Right, but the original topic was about phone and Microsoft's great back porting reputation just hasn't shown up there. There is something hard about the problem and none of the major players are taking that approach (Apple doesn't backport, just supports old hardware with new versions until it unsupports them).
Just saw the answer on another HN thread: http://news.ycombinator.com/item?id=4168959
Different schools teach different things; many don’t introduce colour theory at all. And it’s an odd thing, but most people don’t know intuitively how colours combine or invert. Of course, as a synesthete and maybe a tetrachromat, I’m not really statistically relevant to this discussion. ;)
Except that the 3GS isn't getting iOS6. It's lacking features from iOS6, such as Siri. Apple permeates this lie in order to fool you, the consumer, into thinking that they're completely 100% keeping everything up to date. While I agree they are doing a good job, they're still lying, and consumers (especially us) should be smart enough to see through this.
Martin, what an awesome thing to do to help us. I considered myself a designer until my brain got blocked churning out new design ideas and now I can surely use some feedback and help on my site and mobile app. I am looking for feedback on my project at http://www.findero.us. Thanks a bunch.
Hey Arun, just wanted to say that I was a (burned) WakeMate customer but once I got a hold of you I did get a refund. Sounds like you hit some rough times, but I appreciate how far you guys actually got. Good luck on whatever comes next.
"In reality, there is, perhaps, no one of our natural passions so hard to subdue as pride. Disguise it, struggle with it, beat it down, stifle it, mortify it as much as one pleases, it is still alive, and will every now and then peep out and show itself; you will see it, perhaps, often in this history; for, even if I could conceive that I had completely overcome it, I should probably be proud of my humility." Benjamin Franklin (emphasis mine, and added only semi-seriously: how do I discuss the humility I take pride in?).

The concept of "binning" has to do with the manufacturing process for chips.

They're such complicated devices that even if they do everything correctly, in a given batch of chips, one may do it at a slightly slower rate or only stay stable at a slower clock speed.

The chip manufacturer takes this into account and separates out the chips according to performance, with a low-high scale, which makes up the "family" of processors that they offer.

However - there is a certain amount of business process involved in the sorting as well. Chips with higher performance rating marked for a "high end" bin will result in a larger sale / dollar amount for that chip ... but it will also, in the end, increase the availability of that "high end" chip. This availability may not be entirely used by the market - and may result in a surplus that will actually drive the value of the chip down in the end. In addition, the middle range (commodity) chips will be in higher demand anyways so you'll want to have an abundant supply of them in general.

I think the parent comment was suggesting that Intel is more interested in keeping chip supplies for higher end processors low (thus scarce, thus valuable on the open market) and is willing to "underbin" a chip to help control those prices - whereas AMD is apparently strictly binning them based on pass/fail/rating/performance.

The end result is that you're more likely able to overclock a commodity Intel chip and have it stay stable because in reality it's likely "overqualified" for the processor label within the family it's sold under.
I think they mean this:

When you build a CPU factory, it can cost a lot of money to set up the manufacture process for a chip.
You want to sell a number of different chips at different speeds/prices (if you have a cheaper chip lower in the range you can charge top dollar for the fastest one).

You don't necessarily want to setup that many separate lines though, so what you do instead.

You make (let's say) a 3Ghz chip.
You then test each one at 3Ghz, ones that pass are sold as 3Ghz CPUs. Ones that fail are tested again at 2.8 Ghz (or whatever) and so on until they find a speed they are stable at, they are then sold as that speed.

The implication is that AMD does this , but Intel will just take a chip that works (or might work) at 3Ghz and sell it as a 2.8Ghz because they don't have enough faulty (as in only run stable at slower speeds) chips.

What this means is that overclocking potential will be better on Intel chips because they have a higher chance of being stable at higher than the advertised clock speed (basically you're not overclocking so much as un-underclocking).
Generally API features of newer versions of Android are backported and made available through the compatibility library, so it's common to get features of newer OSs on older devices (a major exception to this is Google Chrome which is unavailable for pre-ICS devices).
Sorry. What I meant was, web applications have been a successful cross platform way of delivering software for the past 10 years. I don't see any reason why it can't continue on mobile, especially now that the hardware is catching up.
Did anyone ever predict Saudi Arabia would actually reduce the price of oil as a method of economically attacking it's enemies?

There exists academic literature suggesting that oil producing states would, if threatened with technological change which had the possibility of making oil obsolete, respond by flooding the market with cheap-as-water oil with the twin goals of a) killing or delaying the new tech (newly irrelevant because, hey, it is now 100x more expensive than existing technology per unit of energy) and b) transferring as much from their below-ground Swiss bank accounts to their above-ground Swiss bank accounts before their nations collapsed.

I thought green was the colour humans saw best, if best means brightest. For instance, when converting from RGB to greyscale the usual weights are 30% red, 59% green, and 11% blue. (Though I always found it kind of unfortunate that these weights are wrong for people with nonstandard colour receptors.) In that sense, green should (seem to) be the largest because we perceive more colours as greenish than as reddish or bluish.

I disagree. Most of my peers own an Xbox360 or PS3, and those that don't have some kind of Roku / NAS / whatever setup. I think fewer and fewer young people have cable boxes, they are fine with just a solid internet connection. There is, of course, a huge existing install base that is not going anywhere soon.
That's also a ton of tying and a lot of code that a minifier can't reduce. I guess its possible, but do you really want to writing such verbose code?
It's been known for a long time that the Iranian cost of production is much higher than the Saudi cost (basically Saudi oil is free ($1-4/bbl); due to sanctions, Iranian oil isn't profitable at less than around $50, and they need it to be >$80 to sustain their overall economy.

Saudi Arabia and the US have been long-term allies, and Saudi Arabia and Iran have been rivals, so it's always been likely Saudi Arabia would sacrifice some marginal profit to hurt Iran.
I think Ash Maurya's book "Running Lean" should be on this list and probably near the top.

I suspect two reasons for that.

Firstly, Google is on a social binge. They push G+ with everything they have and that demo was probably partly designed to contribute to the subliminal image of G+ being "the future". Also noteworthy in that regard the casual placement of competing products (apple) in an "also-ran" fashion.

Secondly, Google is probably fully aware that they don't need to promote the glasses to industry and military. These sectors will adopt the technology without a blink anyway and are probably already in touch. There's little need to address them in a public keynote, those battles are fought in dim conference rooms.

Instead Google seems to be using their earliest opportunity here to gauge and tease the inevitable yet still completely unknown consumer potential - basically exercising their first-mover advantage.

Then again, if you were to draw conclusions from their terrible choreography and execution of the keynote (you know, the 2 hours before and after the parachute jump), it might just as well all be completely random and I'm merely reading way too much into it...

He's got one minor thing wrong -- in CMYK, black isn't there to save money, it is because that in theory, CMY mixed will produce black, but in reality the ink's aren't "pure" enough, so they end up being a muddy color. So the K is there to produce the darker blacks.

Also, a) Ink is translucent; light goes through the ink, reflects off the white paper, goes back through, and that affects the color change of the light. Therefore ink uses CMYK. Pigments in paint are opaque, so light reflects directly off them. In this mode, Red-Yellow-Blue-Black works. For monitors, light is emitted not reflected at all, so that is why they use RGB. Oh, and many colors can translate from one model to another, but not all of them. Some can only be expressed in RGB but not CMYK, others can only be made in RYB.
Wow, just wow.

This is what happens when someone who knows a little bit about how the eyes and brain interpret colour decides to write an article where they fill their gaps of knowledge with mistakes instead of doing some research. Since the author wanted to talk about the eye, they should have kept to additive colour only and not tried to be confusing by introducing subtractive colour, which they neither understand or present factually.
[From a senior devil, instructing a junior in the temptation of a human:]

"Your patient has become humble; have you drawn his attention to the fact? All virtues are less formidable to us once the man is aware that he has them, but this is specially true of humility. Catch him at the moment when he is really poor in spirit and smuggle into his mind the gratifying reflection, 'By jove! I'm being humble', and almost immediately pride--pride at his own humility--will appear. If he awakes to the danger and tries to smother this new form of pride, make him proud of his attempt-- and so on, through as many stages as you please. But don't try this too long, for fear you awake his sense of humour and proportion in which case he will merely laugh at you and go to bed."

Yeah, one of the major UX failings of the iPad is the way the notification shade is handled. It seems extremely out of place on a tablet. I'm surprised the Nexus 7 seems to have a similar style shade.

Also centering the buttons in landscape mode? Seems like it could be inconvenient.
This is a moving story; I would tend to agree that he is fortunate to have been doing what he loved, with those he loved, even if he was taken before his time. I recently witnessed my grandfather going through years of idle physical and mental deterioration until he passed, though at a considerably more advanced age, and it was difficult for us, his family, and I'm sure especially for him to go through as well. I am sorry for your loss.

- The significant increase in number of rows is because of throughput. The experiment was run for the same length for all three databases, but MemSQL sustained a higher throughput, resulting in more data inserted. Refer to the simulation code (https://github.com/memsql/bench/blob/master/benchmark.py) to see exactly what is going on.

- We actually print information about row overhead to stderr/memsql_tracelog. The best way to find out is to run this experiment yourself :-)

- Data gets inlined for smaller types.

I was an early adopter of App Engine who went through Ye Grande AppEngine Datastore Debacles. Months where it didn't work followed by a sudden tripling of the cost that turned App Engine into something that was no longer feasible for my app.

Hiccups aside, which I agree is universal, the scrolling performance in-particular with Android devices just seems atrocious. I remember playing around with the GNex when it came out and just moving between home-screens was full of lag. That's with ICS.

>But there's no frequency on that graph where M (green) is active all by itself. So you've probably never in your whole life experienced a pure "green" sense input!

I wonder if there is a medical condition out there where someone is missing the L (red) cones in their eyes - in that case they COULD see pure green sense input. In fact despite being disabled, they could see colors that everyone else is unable to see!

edit: It does seem to exist, protanopes (a severe form of red-green colorblind) are missing the red cones. So if I understand correctly, while we tend to think of them as having a restricted spectrum, they may actually see some colors that others can't.

Looks like a solid Android gaming device. The Kindle is pretty nice in that aspect. There still is really no competitor to the iPod which holds down almost half of handheld gamers on the iOS platform. Android has no match for that still really being solely phone based for the smaller devices for the most part.
The only useful innovation they've found lately is Google Hangouts. It makes sense that they'd like to reproduce that success here. Augmented reality has never been proved useful: on the other hand, people share photos all the time.
