I think what they're trying to say is that the types of electric motors used in vehicles (like switched reluctance motors[1]) typically require a computerized controller that someone has to program, and therefore has an additional point of failure from a software standpoint.

However, I'm pretty sure any modern internal combustion engine will have a highly advanced ECU computer too, so this is sort of a non-issue (though I'll admit I don't know much about aircraft engines specifically).

Can Sfeed run entirely in a browser? I should of said my goal is to be able to run this on my iPhone without an app. I was thinking of using GitHub pages as a host.
If someone gets a bomb on a train we'll figure out how to lengthen train station time...
Somewhat regarding meeting length. I learned in Marine boot camp that if a group is asked, "any questions?" that first, you do not say, "No" because then anyone with a question can't be heard. Second, under virtually no circumstances should you actually ask a question.

Obviously the second has its exceptions, but for the general meeting where everyone is present, a question should be confined to something relevant to everyone at the meeting. Instead, what some people here is, "What would you personally like me to discuss with you?"
Actually the European courts struck down Privacy Shield. So any company transferring data to the US is doing it illegally. Plenty of active lawsuits against google. But as much as HN likes to bash google, people here are pretty submissive when one is asking for advice on legal options against these companies.

They had this rule at America Online when I worked there early 2000s. It was routinely violated by the managers, and was really only in place for the rank and file to cover their butts. I just assume bad management and executives of Facebook routinely violate peoples privacy by digging through their information, it’s there, and Facebook hasn’t exactly shown an interest in protecting privacy.
> many payroll softwares will test decently

That's certainly the impression I got from working in this field for a while. I've worked on one of the products on that list of UK payroll providers, and it has one of the most extensive test suites that I've seen. And some of my colleagues there had previously worked for its competitors, and they mentioned similarly good test coverage there.

I'm sure the quality & amount of testing varies a lot between different products, and I have to imagine there are some dreadful ones. But at the same time, I don't think having thorough test coverage for this type of product -- especially for the parts of the product that deal with monetary calculations -- is particularly unusual either.
Time for more service decentralization.
Holy shit. Growing up in a super small border town between Texas and Mexico, I've seen, heard, and been part of some crazy and terrifying stuff, but nothing compares to this. I felt terrified just imagining what you went through.

Obligatory glad you made it out, but seriously- had any one thing gone wrong, who knows what could have happened in the end.

I used to sit and wonder about the future. As in how wonderful it will be and what amazing things we will accomplish. I used to fear dying because I wouldn't get to see any of it, much less the end of the story. Somewhere along the way I began to fear the future, to the point I didn't want to have children, I felt it unethical to knowingly bring an innocent life into that kind of terror.

Professor Farnsworth said it best- 'I don't want to live on this planet anymore.'

Edited to add- when I was young I caught wanderlust pretty hard and traveled most of the US, some of Mexico and Canada. I dreamt of visiting other countries and continents and was hugely disappointed to not find a way before having a family and obligations. All that went out the window about the time I started watching Locked Up Abroad. Brokedown Palace had nothing on those stories.
In the case of MasterCard that might be true, but the law applies generally. It's not inconceivable that another piece of critical infrastructure could be provided by a country who has a data center in a more likely adversary, say, China. In general, the Indian approach is not to whitelist everything and then blacklist whatever specific exceptions become necessary, but the reverse.

As for avoiding war: sure, but how should we conduct things until utopia arrives?
The thing I can't believe is that Japan's trading partners like USA, Canada, UK, Europe etc. haven't said boo about this outrageous miscarriage of justice in which the Japanese government has been complicit. As for as I know not one government has spoken out publicly.
Do you have actual production experience with RedPanda? If so I would love to hear about it- we found out that there is something of a wall of 10k partitions per broker before things start failing/under replicating without warning or any issues outside of the URPs. This appears to be a limitation of zookeeper and fetching metadata. We are fighting this by raising timeouts and such, but this blindsided us, and really the solution is to get people to stop creating topics with dozens of partitions when they aren't needed.

I took a look at redpanda this week, it sounded nice on paper, but them being a young company, I am concerned about what "gotchas" we are going to run into.
What's the purpose of being able to embed an image in the sheet? Is it intended to be an aid to `tracing' an image when creating ASCII art, or does it have some other purpose?
It’s not zero. Hashed passwords are still passwords and should be treated as such. “Zero” implies that hashed passwords are not passwords, since otherwise you won’t get to zero.

Just because passwords are hashed doesn’t mean you can give access to them willy nilly and happily claim that “zero” people have password access.

In many areas, the amount you pay in rent isn't much different than what you pay in the ITI parts of PITI (principal, interest, taxes, insurance) plus the maintenance costs. On top of that, the difference between mortgage + maintenance and rent could be invested and growing over time.

There's no guarantee that buying a house will leave you richer than if you'd rented during the same time. Check out this calculator to explore your personal situation more closely, and examine the assumptions you make about growing wealth.

I know from personal experience, owning my first home, that I almost certainly would've been better off renting over that time period and investing the down payment and higher monthly payments than I ended up with having that house and equity. Sometimes you get lucky - and house prices go up and you sell at the right time (assuming you switch back to rent OR manage to then buy in a market where prices are lower than average.)

Small aircraft can operate from regional airport which are much, much faster to board and disembark from then the large airports that behemoths have to use. I really don’t understand all the hate for a smaller electric aircraft. There are tons of advantages, and the difference in pilot labor costs are practically trivial. (I think a big driver for larger aircraft had been reducing number of engines per passenger as jet engines are expensive to maintain and the larger ones are also more efficient, but this isn’t really applicable to electric motors.)
"like passwords" probably comes from the journalist and doesn't actually mean that anyone has access to passwords.
>They further said that if you need to access any sensitive personal data, or if you need to log in as a user in order to debug a problem, you need to have approval from your manager _before_ the access, not after.

But were you still able to just look at the data or login as the user without the permission? I think that's the key question.

Talk is cheap. As a user it's not good enough for me that people are being told internally not to abuse their access. Just remove the permissions from the employees and make them request the permissions for each individual case instead of trusting the employees to follow the rules.
Cryptocurrency in the real world (as opposed to rhetoric and original intent) is more about censorship/suppression resistance and resilience than decentralization.

A coin might be fairly centralized, but the centralized coders and miners are replaceable in an organic fashion. If they were all shut down others could pop up and even if there were forks one fork could eventually triumph over others.
I'm surprised that this stuff is audit only. At my company, at least in the past five years or so, this type of access has been forbidden to almost all employees. You need to request access to these types of systems and provide justification for why you should have it. Access is controlled on a per-system basis -- it's not blanket access. Many of the most sensitive systems have auto-expiring access for humans.

Nowadays we are seeing many systems switch to a regime where you have to get another engineer to sign off on any access to production, and your access is limited to at most 24h. This isn't merely a policy -- it is enforced by technical controls that forbid ordinary human-user access to production. I literally cannot even send an RPC to services I work with that handle private data without getting a colleague to sign off on it.
Keeping people out of jail keeps people out of jail
As socially inept as we're stereotyped to be, we arguably have more user empathy than the average non-builder/non-engineer, considering how easy it is to build things.
Usually it's in the logs. So small number of SREs can sometimes access them (if there are logged). And even if they are not logged, they can always show up during tcpdump debugging of network issues and such.

Client side hashing could solve this, but almost no one does it.
Hmm, that's interesting, maybe the question should be changed to "any questions relevant to the entire group?".
I know it’s probably just me, but most tech startups look like a Theranos play these days. So much technology, so little real value…

Can’t there be just another meeting back to back ? After ending the first ?
The slippery slope is real.

The power to veto anyone's speech is toxic. Entrusting it to anyone, particularly those in power, is the implicit agreement to forfeit liberty.
Is the password sent to Facebook or does it never leave the client? (Genuine question - I have no idea how modern web apps do authentication)
Could it be possible they mean access to servers where authentication is handled? If you had root access to such a server you could look at memory or packets and work towards revealing a user's password.

I know an engineer, a security engineer at Google who is pretty well-known, who went to work at Google specifically so he could get at peoples personal data. I don’t know if he actually does it, but he boasted quite openly for years that he wanted to be the “architect“ and see everything and know everyone’s secrets. He is now a highly placed Google security employee.

I don't think you can cite the technology that has advanced most dramatically out of all the technologies to support some kind of rule that all technology inevitably advances rapidly.

Yes they'll get better, but they might get 10% better over the next 20 years or something like that.
Education does not necessarily work on certain religious groups.
They probably mean some access to production servers where it might be scanned in memory or otherwise grabbed using debug tooling. Making this possible for 0 people will be challenging and at the least add a lot of complexity.
You seem to think digital authenticity is not important. I'm on the fence but I think its too early to conclude. I didn't grow up in a virtual world but maybe to those who did the idea of digital authenticity is all that matters.
I grew up wanting to be an architect, so I became a software engineer. Theres less red tape and more funding in the ether.

If you do UI, its essentially the abstraction of the architect profession.

Looking forward to an immersive vr web where I can start really building out digital built environments.
A JavaScript API has been considered as a replacement for the user agent string, but it has two big downsides:

1) JavaScript must be enabled. If it's not, then the server can't get any of the user agent data - at all.

2) The server won't get the user agent data until after it has already responded to the first request it receives from a client. That makes it a lot less useful overall. Having to load a page, then perhaps redirect the user using JS based on what the JS API says is a bit untidy.

As far as I know it's still possible to transfer data from the EU to the US under the GDPR if the companies involved have signed a ``standard contractual clause''[0] (the article says this was also a target of the Privacy Shield suit but the courts chose to continue to allow it).

Forging orients the grain structure of the metal in a predictable manner. It also helps remove voids.

Generally, a forged part is going to be free of the voids and surface defects of a casting, and waste less material than cutting from an rolled or extruded piece of stock.
> How about just avoiding wars?

Countries simply do not have the unilateral ability to avoid wars.
E-Mail isn't trustworthy. You may get a confirmation that an initial SMTP server accepted a mail, but that's it. There's also no good way to detect that an endpoint (receiver address) is gone for good to stop sending messages.

You will probably point me to SMTP success messages, but a removed mailbox might only be known by a backend server.

Also mail infrastructure will potentially include heavy spam filters etc. making it quite inconvenient. Not even mentioning security aspects with limited availability of transport layer encryption with proper signatures.

If you already own a domain, you can also pretty trivially (<10 lines of bash) implement your own dynamic IP address support with your DNS providers (my solution uses Cloudflare).

In a nutshell: `update-dns get-my-current-external-ip-address $MY_DOMAIN_NAME`

You can have a subdomain like `vpn.yourwebsite.com` point to your residential IP. It may take a bit of fussing to get the ports and such right. But otherwise it's "just worked" for me, for the last 6 months.

Useful if you want to remove the dependency on yet-another-service-provider that can go out of business (the dynamic-dns people).

Timeline for the report was the back half of 2020.

India and the US were the top requestors for take downs. There are new laws in India and some other countries regarding control of speech online.

I wonder if the US based takedown trends will continue into 2021 with the new administration.
Just firing is not enough for the cases of personal data abuse. What I would like to see is those employees being reported by Facebook to the authorities to be further legally prosecuted.

[Feedback requested] Launching new synthetic data platform for devs
Hey hackernews! Today we're launching a new product release to the world and would love your feedback.

At Gretel, we build APIs to help developers create their own synthetic data to power their pre-production environments, or to train downstream ML models and tasks with artificial data vs. real customer data.

Our goal is to make data safer for developers by building privacy in to data.

Here's our theory: With provable privacy guarantees comes community trust, and with trust comes the ability for us to share and collaborate with data more freely. With access to safe data, Gretel enables an ecosystem where it's more about what you do with data vs. how much you have.

We would love your help and feedback to build a better product. Check out our release blog here:

"No company the size of Facebook is going to be storing plain-text passwords in 2021 on purpose."

In principle, smaller planes could have a shorten airport time and use a closer airport.

I don't think it will happen, or at least that it will happen any time soon, but this is one problem that can be solved.
Agreed, I was there at the same time, and was taken pretty seriously, and grew progessively more locked down as time went on.

A friend of mine worked at a large bank in customer service and this was also a big part of their training, and there was even a speech trainees were given before going to their desk at the end of training. He said, almost invariably, that at least one person from every class was fired within hours for looking up the accounts of someone they knew or a celebrity.
Yes, it's a clickbait title.

Buterin's just put ETH2 back to the end of 2022, keeping PoS perpetually 18 months in the future, where it's been since 2014. So I would recommend counting this chicken when it's hatched, and not a moment before.

It used to be possible (albeit required significant work, but it was not 20 hrs a day of work + school - more like 6-8) to literally work your way through a 4 year degree while working a minimum wage job - including using that job to rent a room or an apartment somewhere, or live in a dorm.

$15k for tuition alone (not counting books/materials/food, room and board) obviously makes that impossible.

It isn’t going into teaching staff. It goes into administrators salaries, bloated programs/overhead in sports, recruiting program costs, fees for housing, fees for food, and ever larger endowments that somehow never trickle down - among other things.

For what is being taught 99% of the time, the economies of scale make $2500/yr for tuition perfectly doable in a typical undergrad environment - if anyone wanted to. And it is done all the time in Europe, for instance.

If you’re taking out a loan to cover all your living costs + tuition than obviously that is going to be more expensive than tuition alone. In Europe where school tuition is covered, there are also separate programs to cover student living costs - which are also not super high generally. My ex-gf got her physics degree from a well known university in Spain, and they paid her $500 per month or week (forget) to cover living costs at the time I believe which was more than enough.

She wasn’t eating imported caviar, but students in general have always been able to get by (and have fun/a social life) without big expenses.

That seems irrelevant as that electricity could be collected and used whether or not it is used for planes. So while that may be a good idea it has little if any influence on whether or not it makes sense to use electric planes.

Free speech is not under attack.

No one has ever had a “freedom to demand others broadcast my personal speech at great technical and financial cost”.

Anyone who thinks “free speech” obliges others to distribute their message is of dubious sanity.

It’s authoritarian af to believe everyone else is your tape recorder.

Edit: of course those who are all about free speech downvote me, proving my point; you aren’t obliged to import my message personally and chose to censor it publicly. But Twitter… they’re not people. Just big black box. So much for HN being a community of thinkers.
I constantly find myself wishing for something in between Haskell and TS. I want Haskell pattern matching and typeclasses with TypeScript's records / structural types. Haskell's language extensions are nice but not strictly necessary.
Every time someone points out how we “have trains already” it makes me think:

It’ll take less time to have operational electric passenger flights than it would to build a new high speed rail route. Particularly in the US (Europe is admittedly much better than the US in that regard).
