agreed. My typical pattern on weekend nights is to sleep for 10 hours (yes 10 hours), do what I need to during the day for about two hours, and then get on the road, I'm usually taking anywhere from 1-2 hours of break doing other things that involve momevent (e.g. exercise, social dancing) within that 12 hours, as well, depending on availability.

During the week (when i work more protracted hours) I'm sleeping about 8 hours at least, and I'm also not beholden to an alarm, so I get as much sleep as my body needs. I think I'm probably one of the most well rested people I know, despite pulling twelve hour 'shifts' three days a week.

Obviously I'm more tired after I do the 12 hour shifts than during the week, but I haven't felt so tired that I was at risk of falling asleep on the road (which happened from time to time when I was in grad school).
I asked an engineer too, and he said exception handling was planned. So that's that :)

Anytime I see a post about football I wonder how it is different from rugby, so I'll just post this intresting article

"In rugby, the only collision (i.e., running at speed for the purpose of forcing a player to the ground) is when one has the ball. The other 29 lads on the pitch are there for support. In American football, 21 of the 22 players had better be colliding with someone on every down - at full speed. In gridiron, there is collision while blocking. In rugby, the equivalent is called "obstruction" and is illegal, thus there are far more opportunities - requirements - for player collision in American football."

WebGL arrives on iOS 8 – and more
I don't know why you're being downvoted for that; your interpretation, while uncharitable, is still most likely the correct one, given Apple's history.

Not to mention the games market for the iOS App Store is very saturated and most of the money has likely been sucked out of it for the time being, so now Apple finds they don't have much to lose by allowing the possibility of OpenGL-based games for iOS which bypass the App Store.

In case anyone is quick doubt or dismiss the above criticism, just recall that for years Apple's iAd framework officially supported WebGL, but Safari and UIWebView did not. This implies that Apple could have released WebGL support in Safari and/or UIWebView any time they wanted; they simply chose not to for for non-technical (i.e., business) reasons.
It probably doesn't, but since they're using bitcoin it circumvents the way that the US government enforces things like the UIGEA - pressure on banks/payment processors to not accept this class of funds. Bovada is a site that offers both sports betting and poker to US customers, but has to do some tricky things in regards to payment processing. Full Tilt Poker was shut down and their funds seized for this reason, circumventing the payments process by claiming that players bought bogus items instead of funds on the poker site.
The point of linking to Weingarten's piece wasn't that the author missed a terrible risk. She covered that risk in her piece too. The point of Weingarten's piece is that it carefully looks at the issues of culpability involved in leaving kids alone in parked cars in situations that resulted in the deaths of children. And it does not come to the conclusion that all such cases should be crimes.

I'm no design or UX expert and this does look smooth.

However, how does this stack up against the recent UX trend of moving away from skeumorphism? Why should a CC number be represented by an actual plastic card that is coming to life and flipping around on my screen?

I believe the future of plastic credit cards is limited given the security loop holes etc. Companies like Square, Google, etc. are already championing transferring money over native internet identities like email addresses.

hm im not so sure. but if we plan to use a single to instance of bootcamp, and companies can use it as a service, signing up their companies and using a single infra, that would be thousands of networks on the same database maybe a nosql db would be better? i am not really an database expert to make this sort of analysis hehe.. never really worked with huge amount of data, like twitter and facebook for example

i mean, im not so sure if a relational database would be the best option
By far the worst part of our legal system is the massive of proliferation of laws over the past few decades that govern every single aspect of our lives -- by far more laws that any one person can understand and remember.

The result is that some of the most honest, ethical members of our society are being charged with felony offenses for "crimes" that 10 years ago might have resulted in an oral reprimand from a boss at work.
This is actually a pretty ingenious way of solving the distance issue for electric cars. As long as replacing the backup isn't egregiously expensive, I don't see why it wouldn't work.

This solves the last issue I have with electric cars (other than cost).
I was never forced to write like that but I have the same habit of wanting to minimize the resources I use and the dependencies.
The article misses one important point about free dynos. After a period of inactivity, your dyno will be come idle. This simply means that the next request will have significantly higher latency as the dyno restarts. This latency becomes even worse if you're waiting for 10 different services to start.

Of course, this isn't a problem if your app gets a reasonable amount of traffic but at that point there's a good chance you're paying for multiple dynos anyway.
Well, the worse case scenario is that a parent takes the child out of the car and a truck plows into them both leaving them alive but severely brain damaged, requiring 24 hour care. The truck driver is poor and has no insurance, and the parent was inadaquately insured too.
I think you missed the parent commenter's point that the reason they took their kid with them had nothing to do with the actual risk to their child (which they determined to be low), but everything to do with the likelihood of having to deal with other parents in a highly-litigious society (which they determined to be much higher).
You totally disagree that it's unsafe to leave a four year old alone in a parked car?
Python 3 is also not meant to run Python 2.x code. It's pretty trivial to port most code from Python 2.x to Python 3, but there's no real reason to do so unless you're writing a library or other project for other people to take advantage of.

It was intentionally done as a 'clean break' release; 2.x keeps doing the same stuff it used to do, and Python 3 changes a bunch of stuff which, in hindsight, makes sense (such as a distinction between 'stream of bytes' and 'string of text', vs. 'stream of bytes which may or may not be ascii text' and 'string of unicode text').

That said, there's no real benefit to moving an existing project/codebase from 2.x to 3.x, and it was never intended that there would be one. Python 3 is for new projects; Python 2.x is for existing projects, or new projects which need deployment in older environments.
The branch is to be predicted (close to perfectly) by the hardware so the branch cost would be like an extra cycle.
> I like the conclusion of the article, which is that concentrating all patent cases into a single court has given that one court too much power. That particular court seems heavily pro-business right now. The legal system works better when appeals court judges across the country make decisions, and the supreme court manages the splits.

The author of the original article probably doesn't remember the days before the Federal Circuit was created. Except for the then-rare cases when the Supreme Court intervened, judicial interpretations and applications of patent law could vary widely among the different courts. The validity of a patent often depended heavily on where the lawsuit was filed. Some courts were known as graveyards for otherwise-good patents. The federal district court in Minnesota was one such place, along with its appellate court the Eighth Circuit.

That often led to patent owners and accused infringers racing to get their lawsuits filed first: A patent owner would try to sue the accused infringer first in a patent-friendly court, while the accused infringer would try to sue the patent owner first in, say Minnesota, asking for a "declaratory judgment" of invalidity and non-infringement. Under the procedural rules, usually whoever won the race to the courthouse got to keep their lawsuit alive, while the second-place filer would have their lawsuit dismissed.

That in turn led to great uncertainty in the scope, validity, and value of a patent. Clients hate uncertainty. That's what led to the creation of the Federal Circuit: To try to bring more uniformity to the judicial interpretations and applications of patent law.
I participate heavily on PH, and while within a particular day you often see some theme emerge (one product shakes the memory of others), so far since inception it's been a really broad selection of "product types".

Many are tech/web/mobile based, but physical products that impress (new backpack designs, mattresses, etc) and other forms find their way into the mix and are some of my favorite finds.

It's highly recyclable. Aluminium oxide (the result of the reaction in the battery) is one of the feedstocks for industrial aluminium smelting. Recyclable isn't necessarily the same as 'efficient' or 'a good idea' though. It's energy intensive (haven't checked the efficiency of 'recharging'), and additionally has, as a byproduct, massive amounts of CO2 even before considering CO2 emitted in generating the electricity required for the smelting process.

I can't see how that a single use battery like this (which also needs swap infrastructure) has any net advantage over the rechargable swappable packs + fast chargers as Tesla use.

Maybe it could have applications in aerospace where existing lithium ion cells don't have sufficient energy density to even come close to a viable solution. But you'd want to compare it to other 'single use' options like synfuel.
So immutability is a code safety feature, except in the case of arrays, where it's a performance optimization. That seems counterintuitive.
Objective-C has added things, but it has largely not changed existing things. As I said in another comment, languages generally do not change — they just accrete.

If you feel like a language is missing something, that might be fixable — but if you feel like a language either added the wrong thing or did something the wrong way (which is the OP's concern), that is a much more difficult problem, because after release you can't take away what's already there without making people angry.

The person was near enough to spot the child and take a photograph, so they could have remained at that distance and call the police if they feel it's necessary, not least to advise the returning parent/guardian that the police were called. In that case the police would probably have arrived and written a ticket or something. Although this would have involved a delay and frustration for the temporarily unattentive parent, it would have been better than the actual outcome involving the issuance of arrest warrants.

One could say 'why not let the matter drop, the Mom came back and so everything was OK' but that's a classic example of hindsight bias. From the police POV, a child was left alone in a vehicle that was later driven off by someone else. When they followed up, it turned out that the person who drove off was not the owner of the vehicle (which belonged to the child's grandparents). They have to at least consider the possibility of malfeasance.
I believe it's more information about how the department has been using it in cases, records of the number of times it's been employed in the field, and I don't doubt they are looking for uses where the police may have used it to gather information illegally.
Maybe if the aluminum could be packaged as a liquid or a gel, it could be pumped in and out like gas.

Another point, I tend to rely on iCloud Keychain and 1Password to store card information.

Perhaps you should ensure it works with those data entry methods?
That is the intent => "the car would still rely on its regular rechargable lithium-ion battery most of the time and would switch to the aluminum-air battery as a backup only if the lithium-ion battery ran out"
Validation on the expiry date would be nice too.
To the contrary, out-of-order execution and speculative execution make precise exceptions trivial to support. As long as exceptions are not frequent, there is no performance pentalty either. It's the older in-order pipelines who struggle with precise exceptions. But there are well-known tricks to work around that too...
You called her an asshole. That isn't criticizing an article. You interpret it as a defense of leaving toddlers alone, but really it's just a story. There's a lot of important points to it, like the fucked up judicial and legislative process, and the fact that all parents make mistakes. It's not a whitewash. It's real life.

I too rode in the boot of the car, but presumably some other kids did that and died in an accident slamming in to back of their parent's heads and the windscreen when the car had to break suddenly. Or maybe they got crushed when a lorry rode in to the back of them.

I actually just noticed the menu scaling feature (new in 14.04) over the weekend. And it is "multi-monitor" in scope as it can be defined per monitor as opposed to globally.

I doubt that feature was approached with a "This better make up for the Ubuntu phone!" mindset.

Some features that may be lacking would be some Ultramon offers, like menu bar buttons to send the window to the another monitor or span the entire set of screens, but now that I run a 3-monitor set up with two in portrait mode, that sort of feature doesn't really strike my fancy. Plus dragging works.
Cleanup can be done with techniques like try/finally, using-blocks, closure nesting like Ruby, RAII like C++, or defer like Go - all completely orthogonal to checking for errors and returning.
Vanadium-boride air is also a promising chemistry (http://phys.org/news/2013-09-molten-air-battery-storage-capa...).

For aircraft, I'm not sure it would be practical, but in theory you could jettison the spent batteries (which now weigh more thanks to the air adsorption) after takeoff, at which point they would fly/glide themselves to a nearby reprocessing station.

> Not directly, no. But in the end it is better for humanity as a whole

I know, that's exactly what I'm saying. This discussion isn't as simple as "this is good and this is bad" in black-and-white terms. We're talking specifically about the fact that poverty rates and growth aren't tightly coupled, and I was explaining why.

> plus you get money from the government if you are unemployed for a while and prove that you are trying to get employed.

This is also what I said (the "soft landing"). Though UI (unemployment insurance) lasts a year or two, so you're sorely mistaken if you think that UI per se functions as a substitute for a social welfare system.
Swift Programming Language Video Part 1
> I have none to hand either, but I'm going to predict that on a modern CPU with typical workloads it will be small enough that it would be very hard to measure.

I write in a language that does (sort of) this (Python!), and I'd argue that I'd agree. Python gives, by default, integers that aren't bounded, so overflow doesn't happen. Of course, under the hood, it must be keeping track of all the bits of the number somehow, and determining when it can't store a section of the integer in the underlying uintxx_t; it must use some sort of overflow here, even if perhaps it's not truly overflowing. Integer objects (for those interested) are 28 bytes by default and more if they get larger; a rough test with multiplication just now seems to take ~25-50ns (compared to ~2-3ns for a int32t in C) and in my experience, most of the time, this doesn't matter.

With this flurry of new languages, I had hoped to see more of "integer" just being an integer, and fixed-sized integers being a special case. Often, I feel I really don't know what the bounds on the input will be. (Sometimes, there aren't, aside from available memory constraints.) Obviously, there will need to be code that needs to run fast and can use a more restrictive type.

Something like, `ranged_integer<0, 200>`, which I can use when I know my inputs should never exceed [0, 200], and has some well-defined behavior if I over/underflow. (Or even, configurable!) In the `ranged_integer<0, 200>` case, I'd expect the compiler/library to be able to easily optimize that into a `uint8_t`. (You could have `native::uint8_t`, which is just whatever the processor has, and you're on you're own, but it's more obvious that you're on your own.)
And the truck was driven by the other parent. Yes, my brain can play that game all day.
This article is comparing apples to orgies(it was in my spell check so I went with it). Since most of the growth in the US economy over the last few decades has been from globalization you would need to look a poverty levels for the areas we outsourced most of the manufacturing jobs to.
I called her an asshole for summing up the risks to a toddler left alone in a parked car as: "He wasn’t kidnapped or assaulted or forgotten or dragged across state lines by a carjacker." That's really how she summed the risks up! It's an excerpt of a paragraph, not the whole paragraph, but it's the only part of the paragraph that acknowledges risk. And those aren't the real risks. The real risks are (a) that you've underestimated how likely it is that the heat in the car will injure your child (she touches on this later and it wasn't a factor here) and (b) that your child will escape your parked car and wander around, practically invisible, in a parking lot full of moving vehicles.

The whole article is full of misdirection like this; appeals to "helicopter parenting", or whole grafs about how enraged she was that another person called the police upon finding her child alone in a parked car.

It's simply a terrible article. It's meant to stir up outrage at the nanny-state and busybody bystanders and mythologized risks to children, but it repeatedly, reliably misses every mark it tries to hit. In that regard, it's at least valuable as a rorschach test to how carefully people think about what they read.
You probably can’t just drop out of college right now and make a multi-billon dollar company.

You don't have to make a multi-billion dollar company. An acceptable outcome for many might be to forgo outside investment, and settle for a company that does a few million in revenue, pays the founders a decent salary, and sustains itself for a long period of time, growing organically.

... I assure you that a VC will want to fund some guy that worked at Google for three years and knows what he is doing over a kid that just graduated from a state school with a couple of data structures projects on his or her Github

Again, not a problem if you consciously choose to forgo that route. Also not a problem if you bootstrap long enough to get demonstratable traction, at which point what you have on your Github likely becomes mostly moot.

Oh, and don’t fool yourself into thinking you can have a “startup on the side.” Running a successful business isn’t a two-hour-a-day-after-work gig.

No, it's an 8-hour-a-day-after-work-and-every-waking-weekend-hour gig. :-)
I don't find that it advocates leaving toddlers alone in parked cars at all. She states in multiple places that it was a bad decision. What it does advocate is that this shouldn't require legal action. The response in terms of police manpower and court time is wildly out of proportion to the risk.
Well, it turns out football is a no-brainer after all, just not in the way your coaches meant.

It's not reversible in the car, but it is reversible in an aluminum smelter. The power cell is turning the metal into aluminum oxide, which is (mostly) how we find Al in its ore form.

So once you burn it out, it gets shipped back to Alcoa and they treat it like some nice clean ore and shortly turn it back into metallic Al. Which is not entirely energy-cheap, but at current prices of less than $1/lb isn't too bad.

You can see where Alcoa would like such a process.

I don't know if the idea of a high-density consumable backup power supply will take off, but it's not a terrible idea until real batteries get much better.
