Which is 1.

This is javascript here, not CSS or images. The default behaviour is to stop everything, download the script file (synchronously) then execute it (also synchronously) then resume. This means the default is to download then execute one JS file at a time (which is why you should always put your CSS files before your JS files).

Concurrent download (let alone out-of-order execution) have to be opted-in via specific attributes:

@async will queue script download (asynchronously) and execute it whenever it can once downloaded. Multiple @async scripts may be executed in any order, depending how fast they arrive and when the browser finally decides to exec them. It is supported in webkit-ish browsers, Firefox (>= 3.6) and MSIE >= 10

@defer will also queue script download but it guarantees the scripts will only be executed 1. between parsing and end DOMContentLoaded triggering, 2. in order. It is suported in webkit-ish browsers, Firefox (>= 3.5) and MSIE >= 10 (MSIE has had it since ~IE5, but as usual its behavior tends to be ill-defined and buggy)

(note: this is for <script src> tags in the downloaded source, not when they're dynamically inserted)
Package also seems to include battery heating, probably wise as li-ion sucks in extreme cold: "The Cold Weather Package adds an upgraded heater for the battery coolant to boost range and performance in the coldest of weather, along with an "improved defrost" grille, heaters in the cowl and the windshield washer nozzles, and inside, heated seats for the second row as well."

You can do morning heating using grid power, trigger it remotely via your phone (they have an app for iphone/droid). I think you also can schedule heating ahead of time.
This is what happens when your PHD is dependent on how important you graduate thesis is.

I understand the urge to make it difficult but when PHD's are dependent on papers people will do whatever it takes and we get a lot of fake scientific papers because people want the degree.

You should be doing research because you are genuinely interested in the results not to get a piece of paper you can show your family and friends to show them how smart you are.

Worst of all the fake research dilutes the value of research papers in general making you question all your assumptions and the papers they come from.
You forgot to add in your list: making a completely new processor ;) Which the linked project actually achieves.
> I'd imagine the same way it's done today, the same way USPS/UPS handles packages - by dropping them on my porch and hoping my neighbors are honest.

These drones have a 10 miles range, I would guess they are intended for densely populated metropolitan areas where it is viable to have a closeby Amazon warehouse. So in most cases simply there is no porch.
This reminds me of a Reddit thread I've saved from more than a year ago:

"Reddit, my friends call me a scumbag because I automate my work when I was hired to do it manually. Am I?" - http://www.reddit.com/r/AskReddit/comments/tenoq/reddit_my_f...

> Hired full time, and I make a good living. My work involves a lot of "data entry", verification, blah blah. I am a programmer at heart and figured out how to make a script do all my work for me. Between co workers, they have a 90% accuracy rating and 60-100 transactions a day completed. I have 99,6% accuracy and over 1.000 records a day. No one knows I do this because everyone's monthly accuracy and transaction count are tallied at the end of the month, which is how we earn our bonus. The scum part is, I get 85-95% of the entire bonus pool, which is a HUGE some of money. Most people are fine with their bonuses because they don't even know how much they would bonus regularly. I'm guessing they get €100-200 bonus a month. They would get a lot more if I didnt bot.

So reddit, am I a scumbag? I work about 8 hours a week doing real work, the rest is spent playing games on my phone or reading reddit...
Here's something I like to point out any time the subject arises. Let's use 39 per 100,000 population as the current accidental death rate[0]. Perhaps you have reason to believe it is lower for you (you don't have a dangerous occupation, you aren't clumsy, etc. etc.) but that is hand-wavey and anyway you can consider it a rough order of magnitude.

Raise .9996 to 10,000th power and you find you will have a 2% chance of living 10,000 years. Raise it to the 100,000th and you get something very very close to zero.

You should also consider all the thousands of different rare diseases that we won't have figured out how to cure even if we do cure "ageing".

Long story short, you should be prepared to die at some point.

>There are plenty of professional investors who have beaten the market year after year, and by a lot more than single digit percentages. Multi-decade returns of 20% and above are well documented. I personally invested in a fund 12 years ago which has returned a compound 21% pa return over that period, so I know that they definitely exist.

>The chance of this happening due to luck is impossibly low.

The chance of this happening by chance to some investors (though not particular investors) in a sufficiently large group of investors will approach 100%. Also, depending on the density of the relationships between investors and the amount of attention they get for their returns, the odds of one of those investors being within a friend of a friend of yours will also approach 100%.

The existence of runs is not evidence against randomness.
The idea is not new. For building systems, tlb argues there should be a random component in all arbitrary decisions.

>So now you have to put a camera and a remote control system with a range of many miles on the drone. And it can only work if there's a line of sight.

Pack it in, boys. Until someone develops some sort of wireless technology which we could use to receive information from the drone as well as control it, and deploys it widely across high population-density areas, this drone idea just won't be feasible.
> The drones could be almost fully automated - fly to this GPS point above the person's house, at which point control is handed to a pilot for the landing & package drop

In the real world, you can't "fly to this GPS point". If this were possible, we would have automated airplanes and pilots would be out of their jobs. Remember the real world has other aircraft and a number of interesting obstacles: power lines, lamp posts, fences, trees, cranes, trucks, chimneys, kites and all other kinds of interesting stuff.

Flying blind to a preprogrammed GPS location is simply impossible in the real world.

Also, remember that GPS isn't quite enough to drop a package right on your doorstep. You need much more than that.

Yeah, we've seen how those stories affected their Black Friday sales, before the 60 Minutes episode: http://www.telegraph.co.uk/finance/newsbysector/retailandcon...
Interesting, thanks for the correction.

I don't think the handover issue is a fundamental problem with the drones though. For example you could receive an automated phone call to let you know the package is hovering above your house. If you're ordering something to be delivered in 30 minutes you're probably going to be there to receive it.

But I still see theft in transit as an issue. The moral/mental threshold is surely much lower for shooting down a mechanical fly than it is for raiding a van.

This could well be a "Cara de pau" strategy where Senhor Ribeiros shows the pics to VCs or other companies, convince them to invest, take their money and literally exit fast.
I suspect there is a lot more to this story. Councils tend to avoid going down this route unless there are no other options left to them. Mainly because doing something like this costs them a fortune and councils hate spending money on children services if they can avoid it.

There would have been a lot of people involved in the process and they are very risk averse people for the most part.

Did you actually try his experiment? You should. Find someone who might actually buy an appointment reminder service --- the person who manages the calendar for a professional services company --- and ask them the difference between .COM and .ORG.

Your "common fact" is "common" on message boards. You have message board blindness, and it's begging you in this instance to spend $30,000 on something that would potentially not improve sales at all. That's a disastrous decision for an early stage startup.
I'm a guy too. I find all that "guys just being guys" crap incredibly obnoxious. It's good for nothing. Only the people infected with it think otherwise, or women with Stockholm Syndrome.

Just as the OP wrote: "Where could we be now if we hadn’t repressed half of our society throughout our entire history?" We already lost so much, so how about cutting our losses, and doing away with the cavemen (which will become easier going forward, since the world kinda shifted from brawns to brains).
even better, the drones can put the package directly on the window ledge :)
In Germany it's normal that you have to sign for your packages and I'm not aware that there is an option not to do that.

That being said, some delivery people simply dump the package in front of my flat and shipment tracking says I (who wasn't home) signed for it. And of course the fun of living in a dorm with 120 people and the illegible signature (are there others?) and you don't know who it belongs to (because the slip of paper in your mailbox just says "delivered to neighbour").
>Flying blind to a preprogrammed GPS location is simply impossible in the real world.

I didn't intend to rule out the need for clever self-flying technology on the part of Amazon.

But comparing the challenges that face an airplane that carries people at very high speeds and altitudes to a low altitude slow-moving drone is pretty silly.

Google's self driving car does this at road speed limits. There's no reason a drone doing 20 MPH with an extra degree of freedom couldn't do it as well.

>Also, remember that GPS isn't quite enough to drop a package right on your doorstep. You need much more than that.

Show HN: Mybema, the result of what'd happen if Yelp + Zendesk collided
Creator here. I've been building this for a long time, in fact this is still my first project from 2 years ago when I started teaching myself rails. The landing page is ugly, I know, but sign up and the rest of the site isn't that bad. promise.

This is a site aimed at helping consumers find awesome brands that will provide genuinely good service. It's also got the functionality for consumers to resolve issues directly with brands (instead of having to do so on Twitter thereby freeing up their social channels to be social). So it's reviews, discovery, and resolution which is why I think of it as a mini zendesk and Yelp amalgamation type of platform.

Speaking of which, if you run a startup, please mail me at claims@mybema.com from your startup's domain address so I can get you started with a customer support platform and everybody can win :)

He then pointed out, it was actually the woman next to him who had actually whistled. She smiled and replied it was her, and she didn't mean any harm, she just thought my colleague was 'cute'.

It's not really a problem about peacocks, or feminists, it is simply a problem about respect, in each we treat others and how in turn we would expect others to treat us.

I find it strange that The Guardian wants to call Amazon's effort a publicity stunt, but when a Sydney company announced plans for the world's first Book-delivery-by-drone back in October, The Guardian was happy to run that story without any skepticism:

You didn't address the weight and the power requirements for it.

The range of the drones is already horrible.

The costs of controlling drones over the wireless networks would be pretty high too.
Fairly solid gains for the most part, although the regex performance regressions are curious.
"Focusing on the additional, costly skillset of coding — rather than the other more essential, but still lacking, types of literacy — is the product of myopic technical privilege."

And assuming that educational resources are bounded by what's currently in place is the product of myopic acceptance of the status quo.

Maybe for the next Wired exercise in futurism, they could imagine an educational system that isn't being suffocated to death by anti-tax zealots and privatizers / privateers...
Nonsense. It's equivalent to a Victorian child tin miner saying to the slave that he's also had a hard life. The set of people who actually owned slaves was always a tiny minority who were only able to own slaves because they were wealthier and more powerful than the vast majority of people alive in their own time.

This is not to say that the child tin miner had a worse life than the slave, but they clearly both have more interests in common than either of them do with the slave owner.
How about transferring human consciousness onto machines? I think its much more probable than to stop the human body from aging and its also more secure. Id at least have two offsite backups of my mind somewhere, just in case you know. And dont forget the encryption in case the NSA gets ahold of it!

Absolutely not. A doctorate is an apprenticeship in research, and the thesis produced is your "final test" as an apprentice. It's supposed to be the start of your academic career, not its pinnacle.

With infinite life the entire concept of wealth changes then. At the moment most people work to better the lives of their offspring because that is how we handle mortality and immortality. You may not live forever but your genes and resources (money, property, photo albums) live on with your children and grandchildren.

With no reason to save I could do whatever I wanted. Walk all the way to Everest, swim the Atlantic, tell my boss to fuck off. As for wealth, I'd spend decades hacking into bank accounts, because why not? What are they going to do send me to prison?

If we could all be immortal it would kinda suck to be wealthy. No one would need your wealth, and if you they did you'd spend all your time trying to protect.

If you read the article to the end, you realize that the author has big problems with Amazon, but they have nothing to do with drones. He is using an uptick in publicity about Amazon to voice his opposition to Amazon's business practices.

As to the issues he raised with the idea itself, the reality is that every single one of the issues will be resolved. This type of delivery, along with privately owned drones carrying out mundane tasks that would normally have us driving around town, is our future. It will happen, the only question is when.
The threshold for destroying a device costing several thousand dollar which is actively having its location monitored?

If a police car is nearby it could be on the scene before the drone even hits the ground and having a few stories of parents getting a giant bill might do the trick.
Oh yeah, in ancient Greek law courts, bemas were raised platforms that two parties stood on to present their arguments and disputes. Hence the name.
Don't have an answer right this minute, but I think eschewing/forbidding variables in trait would prevent the most obvious such collisions.

If you can't override variables, you can't silently change the structure to depend on trait order. You'd have to explicitly state order.

PS. Of course if you have several same signature methods that call super, which is generated depending on order, same problem persist. So, forbidding variables and calling super elements should deal with most "magical" interactions.

Is there?

Is there such a time for real or is this just a society-thing some people thought of because they think it was "good"?
This is cool. I implemented an extremely similar system for my last job. The data was dumped into mongo and then we visualized it with stacked bar graphs.

One thing to consider since you're using a count+total model is that the most interesting timings will often be the 90th or 99th percentile, so by calculating averages you might be missing useful information.

I ran into some issues with the implementation after switching to using an async framework since the code was no longer a series of nested function calls. Since the current best practice is coroutines where this will still work I think it's okay, but you should consider how someone using callbacks might time their code. In my case I was in a hurry so I manually called the equivalent of your __enter__ and __exit__, but it was pretty ugly and left a lot of room for bugs.
This isn't 'guy' behaviour, it is, to use a colloquialism, knobhead behaviour. The kids in the audience who actually wanted to learn something interesting about science weren't wolf-whistling. The people who are perpetuating that kind of behaviour are idiots with a stupid, narrow view of what it means to be male. These are the same people who will use 'geek' as an insult and think that if you don't conform to their idea of how to behave that you're not a 'proper' man. For the love of god I have no idea why you're trying to suggest that they might be right.
That was a weird way to respond. The problem is not the sexualization of the picture, but the fact that they felt the need to externalize it much more intensely than a pack of apes would ever do (seriously, have u ever seen a group of apes whistling because they saw a female?) in a context that is totally inappropriate. Maybe the picture of the sexually starving guy has become de riguer, and it's expected of guys to act accordingly.
I partially agree, but would add that learning to code is valuable in the same way that trigonometry was valuable. It's another way of looking and thinking about the world. The more perspectives we have on problems, the more ways we as individuals have to attack problems.

I've at least found this to be true in my own experience, but I have also sought out opportunities to combine disparate skill sets and knowledgebases. Being able to toggle between thinking like a sociologist and thinking like a programmer has made my work richer by providing me with solutions I might not otherwise have thought of.
