Had to read past many paragraphs of historical filler and other teaser trash to get to the meat:

> Economists have long said that the rational thing to do is to buy an annuity. At retirement age, you could pay an insurance company $100,000 in return for some $5,000-6,000 a year in guaranteed payments until you die. But most people don’t do that. For decades, economists have been trying to figure out why....James Poterba, an economics professor at MIT who has extensively studied American retirement, says it’s still a mystery why annuities are so unpopular. ...But there’s also some evidence that people just irrationally dislike annuities. As behavioral economist Richard Thaler wrote in the New York Times: “Rather than viewing an annuity as providing insurance in the event that one lives past 85 or 90, most people seem to consider buying an annuity as a gamble, in which one has to live a certain number of years just to break even.” ... Here is where tontines come in. If people irrationally fear annuities because they seem like a gamble on one's own life, history suggests that they irrationally loved tontines because they see tontines as a gamble on other people's lives.

Right, so the answer is completely known, and now we're just speculating on what weird financial device will best play to people's economic ignorance. Luckily, the author sounds almost as confused, since you couldn't have a handle on economics and write this:

> Retirees often object to annuities because they worry about not living long enough to make the money back. This is the nightmare scenario: If someone dies the day after she buys an annuity, the insurance company walks away with the cash scot-free. In a tontine, that money passes on to help fund other people's retirements.
I though it was going to be a real service - and one I'd dearly pay for (since I often run 18+ days with meetings stacked end to end and cross timezones). However trying to sleep in public on something like a coach class airline seat is not an option - it's like trying to sleep in McDonalds. What these guys need to do is create a day room exchange - a sort of AirBnB by the half hour or maybe day rooms.
For the record, that was (more or less) the original title.
Some humans have an inability to handle driving in good weather, heavy traffic, at high speeds, to avoid drinking, to avoid driving when tired, let alone bad weather.

There's a mostly straight street on my very ordinary and safe commute home. When it's raining at night and the road is wet and reflecting street lights, it's actually very difficult to see the lane markings and make sure you're sticking to your lane. And in those conditions, it's not always safe to be constantly checking your blind spot for a car beside you. This is in an urban environment, no snow, no crests or crazy curves, no risk of fallen trees, and I find that a stressful drive despite having driven that road thousands of times.
I legitimately can't tell if this is a sarcastic comment... I don't live in Mountain View, but haven't seen any of these on my visits.
That's interesting about the bagging. One of the bigger issues with this in the US is that people are just really poor grocery baggers most of the time compared to someone whose job it is.

When there are only a handful of these self-checkouts, you end up with a situation where it is often quicker to wait for the line with the cashier and bagger because they just process customers SO MUCH FASTER.

In college I knew someone who was a grocery bagger for a while, and when we'd go to the store he'd bag his stuff and I'd bag mine. The speed and thoughtfulness that went into the placement of various things in his bag was rather humbling...almost akin to watching an expert Tetris player in the zone.

So ultimately more machines could help solve the long line issue, but that is still definitely a factor as it stands today. Given that grocery stores often leave most of their checkout lanes unattended, I'd love to see more converted to self-checkout to increase overall checkout speed.
Yeah, the context was linked above, it was really just off-the-cuff;

He was asked about 1,000km range:

1,000 kilometers... hmm...

Well, it depends under what circumstances for
a thousand kilometers. As it is, the record right
now for Model S is 800 kilometers (496 miles).
That's the furthest that anyone has driven a Model S.

Now, in order to do that, they did drive at a relatively
slow speed, so, you know, we're talking, I think they
drive at 40 or 50 kilometers an hour (25-30mph) or
something like that.

But I think, my guess, we could probably break
a thousand kilometers within a year or two..

I purchased Google's officially sanctioned charger, figuring the Nexus 5 would be optimized for it. Looks like it has been discontinued:

https://store.google.com/product/nexus_wireless_charger

Are there better ones out there that don't have as much of an issue with placement? My blind assumption was the problem lies with the phone's limited charging area, not the charger (which I presumed was nearly the whole surface).
Well, considering the Google page says nothing about needing power or an amp, yes, I do. And my original point noted that the news articles claim it works with "any home speaker" and "old school speakers" when that is not the case at all. Why would I have a receiver when Google says it works "on your best speakers"?
The problem with this title is that it's the anti-clickbait, like 'Unusual Incident in New Jersey' would be for an article covering the Hindenburg.

I liked the original title; it's a good, well-written and engaging article, and the title drew me to it.
I've always found it striking to note how laid off has migrated over time. When my grandfather got laid off, there was an expectation that he would come back to the same job with the same company some time in the near future.

When I get laid off there is no expectation that my job will come back.
Intel had already price-segmented "inexpensive" supercomputers by restricting ECC to Xeon chips. The good news was that the low-end Xeons were only about $100 more than the Core i7 in the same socket.

We don't know whether Intel will restrict the low-end Xeon PCI-E lane counts for skylake, because the skylake Xeons aren't out yet.

I will be very alarmed if the next generation of 1-socket (cheap) Xeons feature the same sharply restricted I/O as the non-Xeon units.
"Fired" = "let go because the employee did something to deserve it"
"Let go" doesn't not have the same meaning.
I think individual car ownership will disappear. You will commission a car to get from point A to point B (with the options of lower costs if you are willing to pick up passengers en route) and then the car will go on and do other trips. Your own car just sits there almost all the time, that's really inefficient and expensive.
Just to vouch (har!) for the responsiveness of the mod team – I've reached out to them a few times for one thing or another and they've always responded in a prompt and friendly manner that has reinforced my willingness to reach out to them.

this is a kick-butt totally cool idea.

Why? What are you basing this on?

Why would part-time people be any less responsible? They have less to deal with, more time to deliver, use their own car, choose their schedule, and set the radius and familiarity of their route. I'd expect them to make better deliveries and more accurately.

Uber/Lyft have shown this model works fine.
Groupon still has a $2.3B market cap.

My vote is for Fab, which went from $1B to effectively $0.

WJoy is my go-to example of an app broken by SIP: it's effectively a third-party driver to change the properties of the Bluetooth stack (and do some extra higher-protocol-layer autonegotiation magic) so that Nintendo Bluetooth devices will connect to OSX. Absolutely needs a Kext to do what it does.

The number one thing that prevents me from writing "better" comments is that more often than not it's simply not worth it. Either the story is already filled with noise, gets flagged off the front page, caught in controversy filter or your comment gets downvoted because someone disagrees with one things you said or nitpicked on or it's just forgotten.

Evernote is a note taking app in 2015. While slack and hipchat are somewhat iconoclastic, they have network affects and boost productivity. Evernote is competing with apple notes, google docs, whatever microsoft has, every password keeping app, a notebook, a text editor and using a blog. This is something that will likely happen to dropbox and box. You provide storage. Simple math will provide you with the cost of storage in 5 years and it is not a lot. Further, similar to evernote, it solved a problem that had a lot of friction and was novel a few years ago, but is standard now.

Syncing. This is a default piece of all browsers, the 2 main operating systems win/os x, and comes standard on most phones. This is like the browser, you can have it for free so you stay in our ecosystem. Mega GIVES you 50GB of storage completely free NOW, and it is likely more secure. I don't know enterprise as well as I know consumer, but at some point I would imagine the choice is between buying a few SSDs and having an internal server, or setting up your own secure system via VPN. There can't be much room for this.
I have a little "lipstick-sized" charger that gives the Nexus 5 (old one now) a full charge. It's less than $10, just search for "portable phone charger". Honestly I'd rather haul this thing around rather than a spare battery.
Shouldn't editorial independence mean that Michael O. Church is unbanned? Or is Hacker News still committed to Y Combinator's feud with him?
Ah, the death of a unicorn. The operational end is doing fine: "Our paid subscription growth is very strong and almost entirely organic; the number of new paid subscribers is 40% higher than this time last year." But the hype has faded, the $1bn valuation is down, and there's no greater fool available to fund them.

This is a problem with too much funding. You have to pay off the investors, which requires rapid growth, which often requires buying market share at a loss.
Could someone give a quick summary of flightsharing and how this ruling affects it?
I'm trying to learn Rust. The Getting Started documentation on https://rust-lang.org has been pretty interested so far.
I believe that is the case. I highly recommend just purchasing an RPI 2 and throwing the OSMC distro (Debian+Kodi) on it. Kodi supports the AirPlay protocol, so once you enable it in services you can use https://play.google.com/store/apps/details?id=eu.airaudio&hl... and basically pipe AUX out from your phone to multiple devices on your network. :)

This obviously requires the dependency of your phone, but I prefer the flexibility.
I'm hoping they're dropping the idea of chat. Spending time on that really never made much sense me when their core product is so strong but badly needs some features to better align with modern tech trends such as improved plain text and markdown support.
Naw. I hate using whitespace for function application. Having a binary operation that's neither associative nor parenthesized is super confusing to newbies.

a+b+c = (a+b)+c = a+(b+c) // Good!
f a b = (f a) b != f (a b) // WTF?

BTW, that's also a good rule of thumb for defining new operators. If your new op ~-^-~ is not associative, don't make it an op!! And even if it is, consider that users won't magically know the relative precedence of your op versus someone else's =^%^=. Looking at you, Haskell.

What are you talking about? The Germans surprised everyone with their mastery of novel technologies - it's how they took over the continent. This idea that they were hapless bozos when it came to capitalising on new tech is just plain weird. People look at novel tech like IR and say "ha, fools!" but for some reason ignore novel tech like stuka bombers.

Of course, you meant OS 10.2 (a.k.a. Jaguar). Otherwise, it's not that impressive ;-)

He did not disclose all the documents. He made a pass through first to protect people primarily. The vast majority of what he passed on were power points and lists of devices.
I don't understand why developers don't just follow Apple's own Xcode example: ship a sandboxed app that, on first startup, offers to run the (elevated) installer for an accompanying OS-integration package. Or does Apple not let anyone but themselves do that?
Which platform are you going to switch to exactly that has a better official update policy than this one?

Not trying to be snarky, but Google's policy is as good or better than most (perhaps all? I haven't heard of a better option, though they may exist) and at least they are completely transparent about it. They also have good policies around keeping the bootloaders unlockable so if they do EOL it and you want to update with unofficial builds, that's an option, just not one they officially support for all sorts of obvious reasons.
That's fantastic. I'll definitely give it a go, my life is measurably better with Spotify.
What are we doing now, about 1 mile per 5 pounds of battery? I don't see it. He has been very good at making promises but not on delivering. With this track record I figure 2020 at the earliest and it likely won't be Tesla. GM will beat him to market with a car of 200 mile range in the 30-40k range.

Reducing weight is a very difficult issue here, all manufacturers try to reduce the weight of their cars and lugging a thousand pounds of batteries doesn't help. Frankly I think all electrics are not ready for prime time, improved REX solutions are better. Traditional engines perform badly accelerating from a stop but can be very efficient one speed improves. So some combination similar to the Volt but with more base EV is probably going to be a sweet spot. (figure 100 EV/300REX).

Plus this doesn't even touch the elephant in the room, long distance trucking where weight is always an issue and range. Neither of which favor batteries.

I would much prefer Elon solve a more constant problem that would start the next generation off on the right track, Tesla needs to lead the industry in electrifying school buses.
Dropbox must have many more corp customers than evernote, no?
That's exactly the case I was thinking about with my comment

1) Police don't care that APPLE doesn't want to reveal its methods, and
2) Unlike the Stingray, it wouldn't be illegal for them to use iMessage evidence in court if Apple provided it to them (especially with the use of a warrant!)
Doesn't matter. Often affordances are only relevant to get you thinking at the start. Once a concept is fully established, the affordance no longer matters.

Consider the use of a disk to indicate that something can be saved. The fact that you no longer save to disk is ultimately irrelevant.
That would be a good question. They're identically spec'd machines of roughly the same age with batteries that are within 1% full charge capacity. They re both on the same wifi, Bluetooth is off. Display brightness varies, but neither is cranked, I'm not sure what else hardware wise could be seriously different.

The biggest difference is the os.

I will concede that usage varies, hers hits Facebook, mine Twitter. And I run virtualbox but she doesn't. We're both running safari, chrome and mail.
I think it's the opposite. Layoffs are when mgmt is at fault. Firings are when the employees are at fault.
Seconded. They pushed work chat pretty hard... Given what the CEO letter mentioned about product focus, I wonder if it's the employees that worked on that that are being let go
Because app developers can request specific sandbox exemptions (so-called "temporary exceptions") when they submit to the app store.

You can view these exceptions by dumping the Container.plist inside a sandboxed app's container, e.g. for Calendar:

/usr/libexec/PlistBuddy -c "print SandboxProfileDataValidationInfo" $HOME/Library/Containers/com.apple.iCal/Container.plist

Look at the keys beginning with `com.apple.security.temporary-exception`.

(Also note that some Apple apps don't have containers, like iTunes.)
Betting on fusion
It turns out it can be pretty profitable to break with the machine model of the underlying data and instead present things the way your users want to see them, even if it makes the code necessary look complicated and gross.

It certainly can, though I think you’re still figuring out a data model first on those projects. It’s just that you’re starting with how the information is organised and manipulated from the user’s point of view, then figuring out an internal representation to support it afterwards, rather than the other way around.
"We're probably only a month away from having autonomous driving, at least for highways and for relatively simple roads. My guess for when we'll have full autonomy is about three years, approximately three years. However, regulators will probably not allow full autonomy for maybe... at least one to three years after that. So, it depends on the particular market -- some markets the regulators will be more forward leaning than others. But in terms of when will it be technologically possible, three years."

Great article! I think that we've lost something by no longer having a culture of mourning. There's comfort to having a common, socially-acceptable set of ways to express one's grief—and to pick oneself up and move on, too.

How do you address the problem that the longest lived participants get the majority of their payout when they are really old? Basically you're just concentrating a lot of wealth into the hands of the long lived and their offspring that they pass it to when they die shortly after getting their large payouts.

I'm now imagining a scenario where this catches on and in a few generations the life expectancy has a major bifurcation, as those that were already destined to live longer through genetics now get an extra boost via inherited wealth.

NASA Astrophysics Data System Is Hiring a Full-Stack Developer
Full-Stack Developer, NASA Astrophysics Data System

The NASA Astrophysics Data System (ADS) Project is looking for a highly-motivated full-stack developer interested in joining a dynamic team of talented individuals working on our digital library system.

The ADS is currently launching a highly scalable and feature-rich platform using a modern development stack: a custom build of the open-source search engine Solr, a highly responsive UI engineered on top of backbone.js, a scalable asynchronous data ingestion pipeline with RabbitMQ and MongoDB, and cloud-based hosting of its services with Amazon Web Services. Our primary programming languages are Python, Java, and Javascript. Your primary responsibility is the design and development of robust software applications and components to support the ADS services, in particular the ADS data processing pipeline as well as its user notification service.

Required skills: Solid knowledge of python and the Linux OS. Knowledge of javascript and its ecosystem (jQuery, backbone.js, D3.js). Knowledge of Java or C++. Knowledge of web standards and technologies such as HTML, CSS, JSON, XML, XSLT. Knowledge of relational and document databases such as MySQL and MongoDB. Knowledge of distributed version control and software management systems, in particular git / github.

Knowledge of text or data mining principles, familiarity with machine learning and information extraction techniques, knowledge of semantic computing technologies and techniques, and knowledge of asynchronous messaging queues are desirable.

You provide:

a+b+c = (a+b)+c = a+(b+c) // Good!
f a b = (f a) b != f (a b) // WTF?

So, I suppose, also:

a/b/c = (a/b)/c != a/(b/c) // WTF?

> BTW, that's also a good rule of thumb for defining new operators. If your new op ~-^-~ is not associative, don't make it an op!!

Why should associativity be a requirement for a new op? Its not universal among common standard binary operators, after all (particularly division and exponentiation are not associative.)
Anyone know which offices? How many employees does Evernote have? Were layoffs mostly from closed offices?

Edit: the Business Insider article (which maybe should be retained as the link?) has some of the information: 13% of workforce let go. Taiwan, Singapore, and Moscow offices closing. I couldn't tell if the 47 were from these offices mostly. I wouldn't think a note-taking app/website would need to be too dispersed around the world.
Fired does not imply wrong-doing. Fired can be termination w/out prejudice.
I mean, even pilots have to take control sometimes. In great conditions autonomous cars will arrive quicker than many believe. However, most people (myself included) would NOT trust an autonomous car, essentially operating in beta, to navigate a new england winter. That functionality is going to come and can even be pushed OTA later.

I now wonder if you will just pay $199 for the "blizzard package" or something. I suspect Tesla wouldn't do something like this, but just like Mosaic, they get to shape a lot of the early thought behind this.
