> in which planes' flight paths are set

They're 'set' in the sense that if communications is lost between the pilot and ATC, there's a pre-determined and more importantly pre-authorized path for the aircraft to fly through.

> A plane on autopilot would never have to dodge a pedestrian

It happens quite a bit, which is why we invented TCAS. [1] A common misconception is that _all_ traffic is required to file a flight plan, and that's only true for IFR (instrument) traffic and not for VFR (visual) traffic. So, an IFR flight can, and will, encouter VFR flights that interfere with their flight.

> and would be separated from other planes by thousands of feet.

In certain situations, in transit regions and during clearance/delivery, this is not true.

Just a fan. I did several co-ops at west coast tech companies (San Francisco and Seattle) that gave me ample opportunities to see my favorite bands touring. I kept track of my concerts with a spreadsheet: https://docs.google.com/spreadsheets/d/1XIwkqPQmxT6jZE5UMjxU...
The plasma hits the wall, cools rapidly and you have to deal with hydrogen gas and a slightly warmed wall. The thing about fusion reactors is, that the energy densities at any given moment are actually not that high at any given moment, it is just that the fuel cycles are quite rapid and consequently you can get a lot of energy out.
Awesome! I used Mike's original tool a few years back, got rid of a lot of my twitter. Probably time to do it again with your fork :)
You'd have to try it for yourself I guess. I loved Lisbon as a place to visit, but living there was a totally different story. Sadly (and apologies to the Portuguese here) Portugal is a harsh country to immigrants, especially Brazilians from what they told me. Frankly I'd say the only thing Portugal and Brazil have in common is the language. My opinion only.
What's funny is that it's not like anyone is teaching teenagers proper coping mechanisms. They don't come up on their own. Knowing how not to worry about things is exactly that.

Instituting a more responsible testing program would both signal that they are dealing with the matter and also reduce the possibility of further deaths.

Those that indicate a major screw-up do, such as the Explorer rollovers (or Chevvy's ignition switch issue, for that matter).

I don't think the NTSB would be upset if the statements about these autonomous-vehicle accidents were purely factual, relevant and without self-serving commentary and innuendo.

Bitcoin network is with us for the last 9 years and more stable than any other internet service (except maybe internet itself). The slides don't have any prediction (price going to $0 in 3 months after a 9 year climb?). Without that it's a totally unuseful waste of time to listen to it.

Maybe Bitcoin ,,shouldn't'' work on paper, but it IS working in practice.
A suggestion for the author: Please avoid commas (or dots) as thousands separators. My brain parses "4,604ms" as "about four milliseconds", which would be amazing, but is very much not what you mean.

ISO recommends half-width spaces as thousands separators to avoid this kind of confusion. Also, I think thousands separators can just be skipped if your numbers are only four or five digits wide.

I started doing jiu jitsu after having a long conversation with my teenage students about video games. We all agreed that they are a wonderful way to burn some time - but also fully acknowledged that they only provide the illusion of accomplishment. Simply having fun is absolutely worth it, but so many games now require you to grind beyond the point that it's playfully fun. At the end of a long gaming session what do you actually leave with?

Jiu jitsu is still a game of sorts; however, this game causes me to work out more intensely than I could ever do just by cranking out sit ups at the gym. I can measure my skills development pretty accurately based on what techniques I can pull off on skilled opponents. Abstractly, I can defend myself better (though that's not my purpose) and I prioritized it in my life so I can go roll with friends a few evenings a week.

Look into a physical hobby. It has been an important change for me.
Thanks for replying! I plan to try that.

The tech404 slack has been lit up talking about the nuance consequences of this for weeks.

This will have a subtle effect over all developers in Georgia. This would shift liability onto you 100%. You could become the scapegoat for the next equafax, and everyone would pursue you for the losses.

Notice how there was originally a limit to the penalty, and now there is no limit. Life in prison could be a real possibility for something as simple as stumbling onto an undocumented feature of a public API.

> Ceph has some weird failure modes

No argument.

> radius of failure absolutely includes the entire cluster

Completely agree, same goes for any other storage system, network-based or otherwise.

I'm simply disagreeing with a blanket statement that all network block storage is unreliable, and that is simply not true.

Don't do silly things with Ceph, don't just have a single network fabric, don't buy cheap switches that drop packets on the floor at medium load, don't test things in production.
Were you ever initially evaluated by an audiologist for your hearing loss?
Not that I really want to defend KPMG here, and this is obviously entirely anecdotal, but my team had our application code assessed by them (by request of the customer, so they could get some pointers on what kind of development they needed to focus on). I spent 2 days talking to them, answering questions, showing them data flows, database layouts, system diagrams, etc. They also required access to our source control (making the "let's remove this before the audit" idea pretty useless), issue tracker, etc.

The 2 people that I was in contact with were both competent and experienced. Definitely not "young grads who have never worked in an actual IT/software dev team" as someone claimed elsewhere.
There's no difference to a behaviourist...
Maybe I'm naive, but I honestly don't understand why governments and private foundations alike aren't throwing money at Fusion scientists. It seems far and away the best possible investment one could make today in humanity's future.
Nobody is going to confirm it in any way you’ll find acceptable (like verifiable list of names/contributions), for one obvious reason: Apple employees tend not to post identifiably in public because articles (like this one) try to extrapolate public knowledge with hilariously wrong guesses at the roadmap, and it creates risk that isn’t worth the trade offs for the employee.
edns-client-subnet leads to a surprising number of privacy concerns. See: https://00f.net/2013/08/07/edns-client-subnet/ I find the cache timing issue particularly worrying.

Cloudflare runs from 151 (and growing rapidly) locations worldwide. Without edns-client-subnet, the upstream DNS server will probably respond according to the geolocation of the Cloudflare location you're talking to -- which is probably pretty close to you, and therefore will probably produce a good outcome for you, while largely avoiding the privacy concerns.
Sure but anyone judging your credit score isn't looking for that. "Paying off debt but not too quickly" or "Carrying enough debt to accrue interest without defaulting" are more likely what they would want to see.

The issue is that this investigation is important to Tesla but not considered 'Major' in NTSB definition. In a major investigations, such as airline crashes, the NTSB are the lead agency who give press multiple press conferences and release preliminary information to the media.

It is considered very bad form for any designated parties[0] participating to talk to the media other than with NTSB approval. Non-essential organizations like union representatives have been booted from investigations for talking to the media.

I don't really think this is correct.

People who have issues getting basic needs met are just unlikely to also get their higher needs met. But I the misunderstanding of needs is also why people do things like smoke and drink and people from more healthy backgrounds don't understand why.

And people have been known to forgo comfort for causes. The basic things matter because without them you will often be in danger, but they don't necessarily matter psychologically.

I think self-actualization, i.e., some degree of mattering, some degree of respect, is important to pretty much everyone, it's just that if you are lacking food and shelter you're also probably having trouble finding a purpose, as well.
> No you're right, the police happily pointed out that the woman was homeless and seemed to blame the victim. Why would they do that?

Because A.R.S says that pedestrians have a duty to yield outside of crosswalks and they normally make the police's accident report available shortly after any accident.

I know because I was over there not very long ago trying to get one for someone else. It's just off of Mill Ave., not very far south of where this accident happened.
Why would the absolute amount of wind energy in India decline so steeply? I can understand a rapid decline in relative share of renewables but it looked like in absolute terms it fell off a cliff. That surely has to mean wind systems got decommissioned.

Well my hat off to that.

I just have a very negative counter-example here though: It was a radio-interview with a green-peace activist on ITER. And they would go to great length, to put the nuclear waste problem of fusion into the same category as the nuclear waste dilema of fission- although the fusion byproducts decay down to zero in 300 years- which is near nothing next to fission.

I really rooted for greenpeace once, but such intellectual dishonesty- with a fundamentalistic approach, expecting humanity to give up civilisation as we know it, instead of working with the humanity they got- lead to a deep distrust to everything they publish.

I really do not know why you (and other commenters later) place such great faith in the add on devices, Roku in particular.

Just from a couple months ago: "And that’s where streaming TV company Roku comes in. Today, the company is introducing a new measurement suite called Roku Ad Insights that lets brands and agencies measure how effective their marketing is on OTT in four ways."

You really should assume that any app you run on any device is gathering data about what you are doing. Could be used in house and/or sold to third parties.
Uncertainty. The risk is much higher investing in fusion than an application.

I'm sure once a proven breakthrough occurs, money will begin to flood in. The potential is massive.

I also find the group is just generally has a lot of "living college liberal caricature" types and can be on a hair trigger.

There was one post with Bill Gates talking his usual vaccines and demography. 1 in 10 comments were to the effect of "Bill is just another rich white dude therefore he's evil". Really leaves a sour taste in ones mouth.

I guess this is the "racism and emotional labor" the mods are fletching about.
I can offer some economic perspective. Oftentimes the critical advance for technology to reach deployment is not a theoretical breakthrough in the primary science but rather a change in aggregate costs, ability to organize capital, secondary technologies, etc. It's stuff that pushes the tech past a threshold of feasibility. The Industrial Revolution itself, for example, was a mix of recent breakthroughs and older ones that started to be realized enmasse(e.g. coal mining and steam engines co-evolved during the 1700's).

So when researchers say, "this supporting piece of the puzzle has gotten much easier," as it is with the new magnets described in the article, that's actually a good time to listen since it might be the tipping point. Theory developments or experimental observations are exciting stories to read about but often have less imminent bearing on whether you're going to see it impact your life.
If you do some calorie restriction, raw cabbage will probably be filling. I've been doing it for two years and vegetables are very filling under the right conditions.

Assuming widespread deployment of fusion reactors and use of battery powered vehicles for transport, humanity's carbon footprint would decrease by about one or even two orders of magnitude, which is the real culprit behind anthropogenic climate change. Obviously that's not something that can happen overnight.
In that scenario, we are doomed anyway: If we would generate anywhere close to that level of power via solar, we would change the albedo of earth significantly -> heating. And we would certainly affect the air currents on a global scale if we use wind power to that extend.
Well, you have the CloudFlare blog where Prince states "The tipping point for us making this decision was that the team behind Daily Stormer made the claim that we were secretly supporters of their ideology."[0] So, all that is necessary is to find this statement. I won't link to it but the Daily Stormer has been active on the clear web for most of the time intervening the seizure of their domain and now. Prince never provided any proof for his claim, not even a screenshot. Of course, a screenshot would have given away, via the visual context, that the statement wasn't from the "team" but from a forum commenter presenting the notion in a joking manner.

As it happens, an internal memo "leaked" to the media wherein Prince admitted he pulled the plug on The Daily Stormer because they are "assholes" and admitted that “The Daily Stormer site was bragging on their bulletin boards about how Cloudflare was one of them."[1] These forums are also what served as the area for readers to comment on articles. Ergo, he acknowledged that he knew his statement about the Daily Stormer "team" claiming CloudFlare supported their ideology was a lie.

You also have to go back in time and consider the context in which The Daily Stormer was successively de-platformed. The site had been publishing low-brow racist commentary including jokes about pushing Jews into ovens and referring to Africans as various simian species for years. It was, however, a single article wherein they mocked the woman who died at the Charlottesville, VA conflict between the alt-right and antifa that led to the widespread outrage that resulted in the The Daily Stormer being temporarily kicked off the internet.[2]

At the same time that Cloudflare was banning the Daily Stormer, they were (and still are, AFAIK) providing services to pro-pedophilia and ISIS web sites. The Daily Stormer itself pointed out not only the hypocrisy of this situation but also the risk it created to CloudFlare's continued safe harbor protections.[3]

Unsolved problems for fusion as powerplant:

-Sputtering of shielding and every other part of the reactor from fast neutrons. If your reactor is becoming brittle as it’s in operation, and requires constant maintenance, it won’t be operating enough to be cost effective.

-Breeding blankets. If we’re not breeding tritium in the blanket (and no one has been able to sustain a reaction that way yet) then we’re just using fission a lot. Expense becomes an issue, as does radiological issues.

-The plasma diverter is very much an unsolved problem. I can get into more detail here, but in short this is the part of the reactor that “skims” some of the hot plasma off to do the work. The dynamics of very hot, magnetically constrained plasmas still escapes us, and when you throw a rock into that stream, the complexity increases. Current divertes wouldn’t last a day in an operating plant. Disassembling your whole plant every day and reassembling it is a non-starter.

-Containment of plasma at sufficient energies is still something measured in seconds, or fractions of seconds. The usual metaphor is trying to uniformly squeeze a balloon; it will just “squirt” out. For s research reactor a second or two of fusion is an achievement. For power generation it’s nothing.

-Neutron activation of otherwise inert materials means you’re going to have serious radioactive waste. It’s unclear just how dirty D-T fusion would be from soup to nuts, but “pretty dirty” seems like a good bet.

-Tritium penetration.

-Most of the energy produced is in the form of neutrons, and we don’t know how to use that as a source of power. Those neutrons, in addition to destroying the reactor itself and activating materials, represent a loss.

-What we really need is aneutronic fusion through alternative cycles to D-T, like p-p, but that’s a much hotter plasma and no one has a clue how to make it work yet.

-Coolant for a constantly running reactor is a boring, but unsolved problem.

There’s more, but these are the ones most poeple on HN probably are aware of when they dismiss this article.

There are so many examples these days. Here's an IBM press release I just stumbled across a few hours ago[1]:

I take it as a reminder to reflect every now and then, when I have the energy to do so.

When reflecting, I check to make sure I'm striving to live in a way that aligns with my values and long-term goals, and that my values and goals still make sense, given my current understanding of myself and life.
I think if they knew where to start making changes, they'd be, you know, making them.

Hmmm. Looking further, the dup(2) man page also mentions "lowest," but pipe(2) doesn't. A documentation oversight, I claim; after all, what would be the point of the kernel not using a single function for "get me an available fd" everywhere that it needs one? Not as reassuring as finding it in the specs, though; here's what http://pubs.opengroup.org/onlinepubs/9699919799/ has to say:

"2.14. File Descriptor Allocation

All functions that open one or more file descriptors shall, unless specified otherwise, atomically allocate the lowest numbered available (that is, not already open in the calling process) file descriptor at the time of each allocation. Where a single function allocates two file descriptors (for example, pipe() or socketpair()), the allocations may be independent and therefore applications should not expect them to have adjacent values or depend on which has the higher value."
