I think people are excited about this because it seems to mesh so closely to the Trolley Problem, which has been an important thought experiment in the study of ethics.

https://en.wikipedia.org/wiki/Trolley_problem (They even have an "Implications for autonomous vehicles" section now.)

So, who knew? Suddenly it's not so theoretical, it apparently has a real-world application. Except, as you seem to be getting at, probably the only thing engineers will be considering in any depth is how and when to brake, not trying to swerve the car elaborately in one direction or the other. The number of occasions when a serious accident occurs because a driver reflexively swerved to avoid an animal or other obstruction (sometimes literally dozens dead in one accident) emphasises that swerving is not so good a strategy as braking. Or, as my driving instructor once told me, "There is only one cause of accidents on our roads: failing to stop in time."

Interesting questions.

Re: Do you require users to purchase a certain number of credits up front after
the trial?

The "trial" is really $2,50 that we give you upon signup. You get another $2,50
after your first "top up". We show the prices in your own currency, so no
"credits", but top-ups start at $5, and go up from there. You can choose to
auto-topup when your wallet drops below $0.

Re: I see you offer refunds if you don't like the story. What prevents a person
from just reading all they like and then asking for a refund?

The refund mechanism is an important tool to generate trust with the reader. We
don't want you to feel "nickel-and-dimed" and if publisher promised a certain
article through the heading and intro, but didn't live up to those expectations
after reading the article, we encourage you to refund, and tell the publishers
why you asked a refund (through a dialog), so publishers can learn as well.

We have certain mechanisms in place to prevent abuse of this system, but we're
lenient, and in general we see only about 10% of purchases are refunded this
way.

Re: Is it possible to copy and paste text from the articles to share on social
media? (I assume you have a share mechanism, but this is more specific).

You can. Again, it's built on a mutual-trust system. So far it has worked out
great, if we ever notice the balance tipping, we'll have to tweak the system.

Re: Once I pay for the article, does it stay in my account forever, or could it
be pulled by the publisher?

It does stay in your account. We don't have any mechanism to actually remove
articles from our platform. Highly occasionally, we remove the content of an
article, because it was published by accident (f.e. a newspaper delivering next
days newspaper too early, and it containing the score of a pre-recorded
contest).

What will the proceeds of the IPO be used for?

Do current shareholders sell part of their shares, or is it newly emitted shares? If newly emitted, will they dilute the founder's shares? Thus, at the end, will this money be used for investment and sudden, huge growth, or will Atlassian stay on their "bootstrapper" growth rate?
If we replace autonomous cars with taxi drivers, we have the same agency problem...but it's not a question people consider troubling.

> A taxi rounds a blind corner on to an inner city railway crossing. Half a car's length across the rails is a small child who's fallen off their tricycle. A steaming locomotive is barreling down the track. If the driver breaks in time, your vehicle will stop short of the child but be torn to bits as its shuttles down the tracks in front of the train. If they maintain speed, you'll just make it past the train -- but the child is not likely to survive.

That's not really the point - knocking down that example doesn't knock down every possible scenario where uncomfortable questions come up.

We were talking about the Trolley Problem at a recent dinner with friends, and one of the guests remarked about how it was like Star Trek; "The Needs Of The Many" versus "The Prime Directive".

So it's a general argument about where a car has the capability of making an uncomfortable utilitarian choice (The Needs Of The Many), or of simply shutting off any ability to affect matters and let nature take its course (The Prime Directive). The uncomfortable bit there is that with the latter, there's still that actual choice (by the designers or whoever) to follow the Prime Directive - it's arguably not "natural" anymore.

But in VR we can have even lower latencies for synthetic content.

Because we have the head tracker recent history, we use prediction on pose trajectory, and can effectively know where the head pose will be at the time the current rendered frame will be displayed. And use that predicted pose to render the scene. That type of optimization won't be possible with see-through VR or AR.

The second optimization is timewarp, where the rendered scene is distorted in screen space after the fact, based on post-render tracker data (just a few ms before display). I wonder if that type of optimization would create artifacts in AR.
There is one flaw in your reasoning: the taxi driver probably wishes to survive himself. Even if the front of the taxi, with the driver in it has passed the tracks, it will probably end badly for him as well.
Keep in mind, Atlassian is not a young startup, it was founded in 2002 and has more than 1100 employees.
Even in the near future, I'm skeptical a car's AI is going to be able to know how many babies are in the other car, such that it decides to kill me instead of putting said babies at risk. It's such a reach as to be silly.

Then if you run the outlandish scenario, and assume extraordinary leaps in AI comprehension in the next 30 or 40 years, it still remains silly. How many teenagers are equal to one baby? How many puppies does it take to equal one 80 year old grinch? There is no scenario under which it will work. Ultimately the AI will not be able to make accurate judgments about morality / character, it can never choose correctly even if you try to program it with what would be strictly subjective value systems - that one flaw guarantees it can never work properly.
3 reasons, not ordered by importance:

1. This is gonna be unpopular, but: the target OS X users for this low/medium priced softwares are more willing to pay instead of pirating, than their counterparts on Windows.

I say that based on empirical assumptions, I have to say, but what I notice is a general cultural difference on this point.

2. A huge part of the web creatives community uses Macs, therefore it makes sense for these devs to focus on OS X

Real-Life Challenges That Can Easily Wake Up Your Entrepreneurship Brain
"The obvious solution is to program the car to never take any blind corner, mapped crosswalk or not, so fast it can't stop on a dime."

In general, that's right. There is no reason for the vehicle to out-drive its unobstructed sensor range.

One effect, which the Google cars already demonstrate, is that their behavior at corners with obstructed visibility is markedly more conservative than when the LIDAR can see down the cross street. That's a good thing.

Having once coded this for a DARPA Grand Challenge vehicle, that's how you look at the problem. You're always plotting stopping distance against the map constructed from sensor data. You figure out how far it's safe to advance given sensor data, and compute a top speed from that. We did this every 100ms. If the map wasn't filled in with new safe space into which it could advance, the vehicle would slow down and stop at the end of the safe area. So it never out-drove its sensor range. Remember, this was for off-road operations, with obstacles and cliffs; we had to be very conservative.

Humans tend to get into a mindset of not wanting to slow down. Software doesn't have that problem. Constantly having a plan available for an emergency stop is not a problem for software.
I disagree, 50ms gives a very noticeable wobble/distortion and will make most people sick in addition to look wrong.
For the sort of "channels" discussed in the article, the UK hasn't used a channel 1[1] for TV since 1985, as VHF was only used for the older 405 line TV system. Newer 625 line analogue TV[2] was and digital terrestrial TV is UHF only in the UK, and UHF channels are numbered from 21.

For convenience most TVs mapped the channels onto buttons 1/2/3/4 for analogue but behind the scenes they would be something like channels 27/29/31/33. Modern DTT channel numbers are also completely separate from what radio channel each TV channel is actually being carried on.

[1] The definition of "channel 1" is different in different countries. https://en.wikipedia.org/wiki/Television_channel_frequencies

[2] BBC2 was UHF / 625 only at launch in 1964, BBC1 and ITV started in 1969 when they introduced colour. Analogue ended late 2012.

By source do you mean way to know what is moral, or reason that there is a fact of the matter as to whether something is moral?

I don't think one necessarily must claim to know /why/ there is a fact of the matter as to what things are moral, in order to be justified in one's claim that there /is/ a fact of the matter?

Moral nihilism can fall down a well. (Note: I mean moral nihilism, not moral nihilists. Rhetoric. I don't have much against nihilists, except that I believe they are incorrect, and it is sometimes kind of scary to need to trust them?)

They should pay tax at the rate set by law.

Do they have a moral or ethical obligation to support the society that gave them life?

Should the Australian government have supported them more than say the coal or car industry? Hell yes. This is a massive blunder on the part of the Australian government. One that has been repeated for decades.

Could Australia be in the position to provide as much capital as Atlassian is raising now? Yes! There is a LOT of money flowing around Australia. Just a small percentage of Super (compulsory pension funds) could have been invested. Even R&D tax breaks could have given more. However, VC invested by Australian funds is tiny (less than 1 billion/year).

The fact is Atlassian left Australia to avoid paying tax. They have even admitted it many times. The Australian government should have done more to keep them there. Maybe Atlassian leaving will actually do more good in the long term, because more people will see the missed opportunities. (not holding my breath on that one).

The AI used in these cars is probability based. They can't be held accountable in the sense that they can't explain their decisions rationally. You can't actually predict what you'll get by slight modifications of probabilities when adding new test cases.

> Nobody at Google is programming these things to calculate the life value of humans.

Well, not everyone at Google agrees with you. Yonatan Zunger seems to think that yes, you do have to work out what the car has to do in certain worst case scenarios.

'A self-driving car, on the other hand, would require that these decisions be specified in advance.'

https://plus.google.com/+YonatanZunger/posts/FMdAD6ckH38

And well, he's right. Once you have programmed the car, it will respond deterministically to inputs. You can close your eyes and ignore the consequences of the decisions you made for the Trolley analogs, but that's willful ignorance of your decisions at that point (and bad QA).

Swift as a language may not be superior to go in itself ( quite the opposite imho), but the fact that go chose a specific type of concurrent programming and built their language around it makes it more straightforward.

With swift, designers chose not to choose. Which means you'll resort to using libraries ( basic threads with gcd or C libraries such as libmill, or libuv), which means future incompatibilities between codebases that chose different models.
And the DK2 was already open for pre-orders since a few days.

This article is a recounting of public story. The real truth is much more nuanced with enough internal reasons (AMD veteran here).

AMD made a lot of profits with the x86-64 (Opteron family) around 2004-2005. However, that got to managements head and there were a series of missteps:

* Inorganic growth: The company went from small teams with startup culture to larger teams with many projects. AMD went and acquired large teams from HP in Fort Collins and Sun in Boston (Millenium chip team) in one fell swoop. This slowed projects a lot while assimilating and learning to work together with very different cultures and methodologies.

* Mid-management from IBM: Since the company was growing larger, a bunch of VPs from IBM were hired. They tried to bring IBM style processes which will not work when you do not have a captive market like IBM and your competitor is Intel :)

* Too many projects: The people and management growth resulted in everyone wanting their own chip project instead of working on derivatives of existing projects. There were too many projects conceived, spent cycles on and then cancelled.

* Paid too much for ATI: Bought them for 5.4 billion in 2006 when they could have waited till 2008 and bought them for 1 billion :) They had to write off most of the ATI value off their books and took charge for it.
