+1. Even if there's no difference in practice, at least a long lease signifies unusual restrictions. Makers of big heavy pieces of industrial equipment also sometimes offer only long leases and never sales.
And how would this help ? The economical problems people face in this day and age are not, at all, that contracts aren't enforced. Quite the contrary.

The opposite is true: the problems people face is that the only contracts available to them, from rents to cell service, have onerous and unfair terms, favoring whichever side of the contract requires investment, and this unfairness goes up to a ridiculous extent.

The last thing we need is more thorough enforcement of them. Hell, I do believe even the owners themselves would demand the ability to "do business". For instance, to let someone hang on to a name and remain in business while they search for a way to repay their debts.
Speak for yourself. I love the radar cruise control on my Mazda 3 Astina, and also value the AEB. I specifically bought this car because of these systems - at the time (mid 2015) it was the cheapest such car available on the market in Australia. It's a 2014 2.5 liter sedan, manual, ex demo. Love it.
Tesla's test and validation framework must be something else. I've never written code that may kill someone if it fails. Not directly at least.

A in-dept report on Teslas' code and system qualification framework would be a very interesting read, I'm sure.
Why is there a difference between sowtware and the car? Didn't you also pay for the software?

Nice write up.

To answer your question at the end, I think it comes down to risk vs reward.

> why not just wait

We can wait, that's an option that's less costly, but more risky.

If something planet-scale happens while we wait on a single planet, the entire species would not make it. If we don't wait and pay the extra price of going to multiple planets sooner, the species has a better chance of survival in the case of such an event.
You can still do that. Just last week I hacked together a quite useable web page using simple HTML and a few <?php-snippets to make it useable :) Don't need JS for everything.
I understand. The measures described in the article about hardening the laptop as a precaution are good, and I would encourage anyone who have concerns about the security of their device to take similar precaution, regardless of whether or not you have plans to travel.

My response above is more about the paranoia some people tend to have when visiting China because of the reputation of its government, when from my personal experience, the people and the government workers of China are some of the most non-ideological, politically apathetic people I have interacted with.
Learning a Language Takes Time
Is that what they're claiming here? It looks like they're just saying that the hardware is capable of it, and that it will beat human driving at some point in the future.
I use it to track my to-do lists at work and take assorted notes.

It provides all the features you would expect from in-depth TODO apps, like arbitrarily-deep task hierarchies, customizeable task statuses, due dates (and recurring due dates), and hyperlinks to other items. Doing that kind of thing is quite easy. But then you can go far beyond that.

I use it to track my time, and a few key strokes gets me a report of how I spent all my time last week. You can also easily track events and look at your agenda for the day, with all appointments shown alongside your deadlines, and then look at the same report for another day in the past/future. This is much better than trying to cross-reference Outlook with a ticketing system to see what's on your plate for a given day.

Some other miscellaneous useful features:

* Support for tables right in the text file (it formats the rows/columns automatically) with Excel-style formula support

* Assuming you do your other work in Emacs, if you're coding and somebody asks you to do something for you, you can do a single key-command to instantly enter a sub-menu that helps you create new TODO items via customizeable templates, and jump right back to where you left off when you finish that

* It supports syntax-highlighted code blocks that you can execute inside the Org file and show the output alongside the code

* Many other reports can be generated, i.e. show me all unfinished TODO items with a certain combination of tags

IMO if you're using Emacs, learning to use Org is a no-brainer, and if you're using Vim, switching to Emacs + Evil just for Org is definitely worth considering.

The article states to use a VPN, but China has now cracked down on them:

https://www.theguardian.com/technology/2017/jan/23/china-vpn...

Your best best (if you can survive on web only) is to ssh to a server outside the country using the "-D" option which creates a socks proxy, then use firefox to connect.. I tried with chrome but it kept trying to make direct DNS requests (which don't work) and I was unable to fix it.

I kinda like your unicorn.

My preferred size would be 8 to 10 inches. I think 10 inches would be a sweet spot, for me personally. Especially since I would want to use the eink screen as a reader as well as a screen for editing. You'd lose pocketability, but gain some additional flexibility and greater readability.

My wish list:

Eink screen, 360 hinge so the thing could be used as a book, backlit keyboard as a stretch goal.

Super user friendly & distraction free writing interface, but with Linux underneath and maybe a checkbox in advanced options to open the shell / vi / emacs for use. One very nice feature would be allowing split screen between two editors, or the editor + pdf / epub. Removes the potential distraction of looking away from the editor when you need to reference something. But no web browser, since that would encourage procrastination, even on a slower eink screen.

Wifi with automatic backups to the major cloud providers or user specified private servers. Plugged into USB and it shows up as simple storage.

Anyways, thanks for the fun idea which led to some fun thoughts. I hope we see something like this one day.
Akamai low TTFB but high download time when compared to CloudFront. Any Idea?
We are using performance API to measure different metrics for the whole request/response lifecycle and compared the result of Akamai, CloudFront, Fastly and BitGravity.

We inserted our RUM scripts on our and customer's website and collected around 2M data points in India.

The common trend so far is:

Low TTFB on Akamai vs high TTFB on CloudFront (which should be good for bots)

High download time on Akamai vs low download time on CloudFront (this matters in our case because images only renders when downloaded completed, mostly non-progressive)

Our test object sizes are 15KB, 20KB and 35KB. All objects are images and our script attaches a query param to skip browser cache, but CDNs are configured to ignore query param, hence always a HIT on CDN. Both the Akamai and CloudFront points to the same origin and have been configured with same settings.

Test object's URL

Akamai - https://akm.imagekit.io/static/img/rum-objects/test-20.jpg?cacheBurst=1497683338625

CloudFront - https://ddhy5lm2tolji.cloudfront.net/static/img/rum-objects/test-20.jpg?cacheBurst=1497683338625

The script being used:

var duration = window.performance.getEntriesByName(resourceName)[0].responseEnd-
window.performance.getEntriesByName(resourceName)[0].requestStart;

var ttfb = window.performance.getEntriesByName(resourceName)[0].responseStart-
window.performance.getEntriesByName(resourceName)[0].requestStart;

The same can be checked on https://imagekit.io (rum.js)

I would love to understand how does Akamai starts streaming response early but ends up late?
You can cheat a bit by making use of laser propulsion[0] to propel a rocket that contains the necessary fuel for deceleration.

To almost completely eliminate fuel requirements in subsequent trips you would bring the self-replicating equipment necessary to scale up the industrial capacity to build an complimentary laser system in the destination star system. This would allow you to propel ships on return voyages and slow down ships coming to the planet.

The downside of course is that you've now built a death laser in each star system that could be used to wreak havoc. But then again in this scenario you've also built self-replicating space bots that can turn asteroids into stuff or planets into asteroids into stuff.

That means a city is in uncertainty if it tries to buy 3 or 4 Tesla to serve as paid minibuses on local territory – neither can a company for a campus, TV channels for a huge studio range, entertainment park to drive their agents around or a shuttle service to the airport who would like to provide limousine services.

This video is from 7 months ago and a concept demo. They would be quite a lot further along now. Read further down: "Your Tesla will figure out the optimal route, navigate urban streets (even without lane markings), manage complex intersections with traffic lights, stop signs and roundabouts, and handle densely packed freeways with cars moving at high speed."
A functioning commercial regulatory apparatus would not allow vendors to call the practice of providing encumbered software licenses in exchange for money by the term "selling software". That we put to with this practice, which basically lives on consumer confusion, is a bug.

It's a lot like our allowing people to sell patent medicines as "supplements". In both cases, we let people distort the meaning of regular words for commercial gain.
I host https://samosasnearme.com/ on Amazon S3 and Lambda. It comes out to 50 cents a month for Route 53 and around $12 a year for the domain. Traffic is pretty low, around 100 visits monthly.
I am not sure what you're asking when you say "how would this help?". Do you not see any usefulness at all in people being able to sell domain names to each other trustlessly without needing to involve a third party?
> What are downvotes representing?

in your case, you're the top comment thread on a front page article. it probably represents "I would like to see a different thread at the top", and you shouldn't take it personally, it might even be because they don't like the discussion happening as reply below your posts.

either that, or idiots. they hide in numbers.
This is interesting, but one of the key points of using a framework is handling browser inconsistencies. If I write an event handler on an element, I want it to work everywhere, without having to write it in vendor specific ways. Does cell achieve this?
You can build fairly complex apps because you own all the components. In real life, you don't always have the luxury: when you have an ecosystem, the core system must be able to support it. Imho you can't easily, and I'd love you to prove me wrong. These are not new problems: older frameworks lived or died trying to solve these issues already.

If cell apps need to be structured differently, how should they be structured? How do you plan to support single source of truth and a large number of third party libraries written with your framework without scope clashes?
I appreciate I can avoid using your framework, but that's not the point :I'm trying to express my criticism in order for you use it (or to throw it away, if you like) - I suppose you submitted your software to HN in order to receive honest feedback.
Here are the first sentences of the first comments on this thread I read:

Is this all that surprising?

I was surprised this was surprising.

I think the issue is local optima.

Does not seem to me to be like that.

This makes sense.

Down with Determinants is a paper, and I guess it is super-clear once you know the stuff already. For non mathematicians, and people who'd like to learn linear algebra? Right...

Anyway, who is missing the role of the basis? It's in practically every textbook, including the one I used.

I agree with the maths that you've written, but it's the same thing that the textbook explains, practically in the same way. The road to understanding is not the same for all people, I guess...
> It was more about not wanting to rot in US prison, I think.

That seems a perfectly rational decision to me.

I'm interested how they plan to solve the problems that the cameras alone cannot solve (assuming they're just RGB cameras with no special dynamic-range abilities) - like white-out snow conditions or driving directly facing the sun (a contributory cause towards the Tesla+truck fatal crash last year) - I understand that only systems with active projection (e.g. Lidar) and beyond-visual-spectrum cameras can provide reliable data... and yet Tesla claims that their current hardware, without these more exotic sensors, is sufficient.
People try these shenanigans every generation or so. See: https://en.wikipedia.org/wiki/First-sale_doctrine
You forget to tell what happened after that.

Someone someone found contract terms (relating to starting a new sub-entity to the DAO) that favored them, started transferring the eth to themselves using this method (they "probably" gained the ability to dictate how the eth would be spent after an initial period, which plenty of people are desperate to point out isn't the same as owning it). And then ...

Humans intervened to have the terms enforced "correctly" (this was regarded as a hack). They even rolled back quite a few normal transactions that had nothing to do with the attack (because just like all other central banks, the ethereum company cannot risk/be bothered to figure out what transactions are about and come up with a solution that affected just the hack and nothing else)

I imagine this will happen again, and again, and again. This is very clear to anyone who's done the least bit of law : humans cannot be trusted (not even by themselves) to write rules and then uphold them "under any circumstances". We must have governments and a legal system to prevent disaster. The easy tricks I see work is that humans can loan eth from others, then have multiple accounts, only one of which is subject to confiscation. Double collateralizing (pledging the same asset for multiple loans, then disappearing with the loans, recently popular in China).

It is a huge job to bring my mathematics up to the required level :)

About the only way I have been able to short-circut the process is outsource to someone who can turn the paper into code - once they do this the maths becomes easy for me to understand.

ESCORT MICHELLE – ESCORTS – ESCORT ATHENS – ESCORTS ATHENS
Great point about career progression. Haven't thought about that, but it just could be due to the mentality on the organsatons I've worked in.

I think that this kind of mentality could be fading away, in time, as more and more organisations require (or just accept the fact) that people prefer to work remotely 1-2-3 days per week. That boosts morale (for me) since commuting is a BIG productivity killer especially in cities with populations way over 5M.

I guess the biggest challenge is that for some people it is difficult to adjust to working from home because they may lack the to "train" themselves, or lack the space, of have the kids, etc.

But "we" (work-from-homers) are winning!!
Microsoft, Qualcomm and Intel: The Windows 10 ARM Dustup
It terrifies me to think of relying on image recognition software to correctly determine an upcoming crossing road (with cars zipping across) so it can properly slow down, rather than get broadsided at full speed. Or a number of other life-and-death situations (which are common during driving). It just seems fragile (what if the 'vision' is somehow impaired, f.ex. blinded by sunlight, or the road markings are wrong or obscured) when the failure mode is so catastrophic.

I suppose once statistics start to prove that these cars are safer than human-driven ones, we can chalk it up to an irrational fear, but for now it seems crazy to me to put my life in the hands of an AI, when a mistake means that I die or kill someone, rather than play the wrong song on Spotify.

I don't fully understand why more effort is not put into a hardware solution, where roads are simply marked up for self-driving vehicles, e.g. magnets lining the lanes or something like that. Of course a more expensive solution, but seems like it would make the vehicles themselves a whole lot simpler and safer. Begin with inner cities, where the area is limited and traffic is most complex.
Vehicle makers are already starting to make that argument, that because they own the software, you can't do anything to the car without their permission:

After going through all the sessions, I think the message is that Apple is going full speed on Swift, regardless how devs might feel like, similarly to Google with Java/Kotlin[1] and Microsoft with .NET/C++.

Besides the LLVM related talks, Metal shaders and real time audio callbacks, there is hardly any C like code to be seen across all sessions.

I should really read that paper, since I'm sort of confused by the threat model. Arbitrary queries seem like they would defeat the point. So I'm assuming this "using a secure, authenticated channel to communicate out, while still being monitored by the OS" model. That's a high bar for software not designed for SGX.

I presume it's relying on the paging behavior of SGX? (Either page faults or dirty bits).

I only recently discovered that in the US many people driving in the left lane will not move to the middle lane to allow cars approaching from behind overtake them.

That's incredibly selfish, not least because it's incredibly dangerous for the driver that has to weave into the middle lane and back again.

Seems bizarre. Then again, you Yanks also don't have kettles, so nothing surprises me ;)
Visual cameras can be blinded fairly easily - even high-end cameras - simply point such a camera at the sun and try to make out a cloud in the sky. If Tesla were using true high-dynamic-range cameras (e.g. Oversampled binary imagers) then I would be more confident - but Tesla isn't saying that they are - and if they really were they would definitely boast about it.

LIDAR also does work great in the rain - provided you have multiple LIDAR units (e.g. Ford's snow-proof sensor array: https://qz.com/637509/driverless-cars-have-a-new-way-to-navi... ).

What I like about LIDAR is that it will never give you false-negative data regarding object proximity (i.e. it will never tell you an obstruction in the road is not there) but visual-only cameras can be fooled very easily and definitely can give you false-negatives regarding road obstructions.

It seems inherently less safe to rely on a more homogeneous sensor array: conversely it makes sense to use as many different types of sensor as possible to ensure your design isn't susceptible to being brought down thanks to a weakness in your predominant sensor type.
Wait - didn't Newton say that a body will not accelerate nor change direction unless a force enacts upon it? Once you set an initial velocity in void space with no air, you should never decelerate unless you accelerate in the direction inverse from your motion.

Correct. There are probably primates that have all the hardware required to drive a car too. But more is required.

Humans are still better at interpreting many things and probably dealing with weather and construction and when there is no data.
Just for the record, no transactions were rolled back. A special one time transaction was generated that moved all the ether from the Dao contact to a withdrawal contract, from which all investors could get their ether back. Majority of the users upgraded their clients to be on the chain with this special transaction. The rest of the people (~15%) remained on the original chain without the special transaction, that chain is now called "Ethereum Classic".
