That isn't really a worthwhile path to go down. Since said vehicle would be barely functionable. If that is the threshold I can wrap copper wire to make my own electric motor and put thousands of potato batteries in parallel to connect to it. Then control speed by manually touching the wires together.

I believe the first EV might even predate the first ICE vehicle.

The Website is Down (2009) [video]
It's a good idea, but the hash doesn't need to be unique or secure.

The IPv4 space is 2^32. The trick is to keep e.g. 24 bits. 2^24 gives 16M possibilities -- unless your web site is _VERY_ big, that means it's a unique ID for most visitors. If you come across an IP (e.g. a scammer), you can also backtrack.

On the other hand, mapping back, you get 2^8 options, so you can't tie back to a unique user.

A nonce is a good idea, but it's not part of the security perimeter here.
Not really. People that need this feature already have it (in a way) - in a given scope (government agencies, universities, some corporations & private companies etc). 99.999% of people simply don't need that level of security. How currently things work is fine balance between UX and security, minimal friction.

They also don’t have the competence to actually figure out that you’re packet sniffing. How would they know?
The fundamental problem is that there is not enough oil. This gets reflected in higher oil prices, which incentivize companies to produce more oil (which is expensive and requires long-term investment).

If you force oil prices to stay low such that they do not reflect supply-demand dynamics, you are not solving the fundamental problem. Supply and demand imbalances do not disappear when you fix the price - they are exacerbated.

Mindset probably has a lot to do with it. Knowing you’re at the beginning vs the end.

Most older people that don’t have Alzheimer’s or dementia are quite aware of their mortality.

We will all get there someday, but I certainly have a lot of respect for those older people that are able to handle aging with so much grace.
Modern aerodynamic designs have mechanical flaps to allow in just the necessary airflow for however much cooling is required. Hot day going up a hill - the flaps open. Cold day lightly loaded going downhill - the flaps close to reduce drag.

An inflatable cone could use the same type of mechanism
Easy way to add auto generated admin panel to Node.js app
Extremally easy way to add administration panel to your NodeJS application. If you're building a startup it's a must use tool!
I work in this space at a company you've heard of - even at our scale and with our resources the proportionally larger attack incentives mean we are constantly firefighting.

> The other alternatives all suck to the extent of my knowledge, they're either prohibitively convoluted, or web3 cryptocurrency micro-transaction nonsense that while sure it would work, also monetizes every single interaction in a way that is more dystopian than the actual skull-crushing robot apocalypse.

I understand the drawback here but I would like to see monetized transactions employed as a defense layer a little more before we make a final decision. It is undemocratic, to be sure, but maybe for those of us who can afford it it's still better than the cesspool we currently sift through on every major platform. Anyone aware of any platforms taking this approach?

Maybe the fediverse will help - by fragmenting networks attackers may have less incentive to attack a particular one.
Tower 9 for Mac is here
Tower 9 for Mac has just been released. This 4-minute video covers everything you should know: https://youtu.be/CuCCGSlBkis

Here's what's new — I'll be here if you have any questions!

1. Merge Improvements:

- Merge UI: indicates the number of unresolved conflicts between two branches. Files now show badges depending on their status and it’s possible to view only conflicted files.

- Instant Conflict Detection: when merging, the dialog will instantly let you know if conflicts will occur.

- Restore Unmerged Versions of Files: developers can rollback accidental actions.

- It is now possible to create empty commits (or skip them entirely) and edit commit messages after resolving conflicts.

2. Diffing improvements:

- Auto-Expand Diffs in Changesets (you can set it to never, always, or for a number of items).

- Large Diff Warnings (you can adjust the threshold in the Preferences, default is 20 kb).

3. New Features:

- Snapshots: stashes that are automatically re-applied to the working copy (to quickly carry on with your work).

- Reveal any commit, branch, or tag in Tower's "History" view.

This is a free update for existing Tower users with a current subscription. New users can download a free 30-day trial.

Also: Tower is free for students, teachers, educational institutions and non-profit organizations.
Basically anything DIY will cost you 10x less than hiring someone. Cooking, car maintenance, home projects, gardening, etc. Many of these are functional skills that are useful throughout life, like basic mechanical/tools knowledge.
I've got all the baseball cards I owned as a 10 year old stored in a persistent database too, but that does nothing to give it value. Crypto is purely a case of the greater fool playing out.

All the drivel about mixers and zero knowledge proofs is the sales pitch of snake oil salesmen (and people who bought snake oil to a point they feel invested in it's value) - yes, the technology is interesting but it's a solution in search of a problem that there's little evidence isn't already better solved by a regulated financial industry.
Oh yeah, just 3 days a week for half a year of some basic barbell program will absolutely change anyone’s life for the better.

Accessing functionality you should not otherwise have access to is by definition a vulnerability. CF apparently agrees since they paid out a bounty for it.
EDIT: I understand your position. It makes sense. There is nothing objectionable with it. Below is what I see where the essence of the divergence of views on this topic come from. Have a great day!

Three highly intelligent and very knowledgeable members of the Court wrote an opinion on why Roe should not be overturned. Their eloquence and reasoning are far greater than mine. You should read what they wrote to see the legal basis of their position. It was not some right made out of thin air as in your Dairy Queen example.

Now 6 members of the court who are equally intelligent and knowledgeable wrote an opinion on why Roe should be overturned. Their eloquence and reasoning are far greater than mine. I read parts of their decision. I disagree with their reasoning. Herein lies the problem.

Human language lacks mathematical precision (I’m a mathematician and not a lawyer) and so we end up in a situation where equally smart, knowledgeable people have completely different conclusions about the same set of statements. This in itself is a cause of chaos.

In what I’ve written to you I have avoided saying things like, “there is no legal basis for overturning Roe”. Clearly there is a legal basis for doing so. Clearly there is a legal basis for not doing so. What I concentrate on are the consequences for this decision. I think the unintended consequences will be dire. Personally I think the Constitution needs to be rewritten. What worked in 1800 isn’t necessarily workable in 2022 in a much larger country with a much larger population.
Show HN: Store Money in a QR Code
What kind of feeds are you talking about? Surely the problem is that there are many things implied by the feeds and only a fraction of them come to pass?
The thing is, cutesiness does not convey anything either useful or specific, and, as this discussion uncontrovertibly shows, may be taken in unintended ways, including as being patronizingly dismissive. This is hardly surprising, as the context in which the error occurs cannot be known to the message's author. One's reaction is immediate and visceral, even if, on reflection, it probably was not intended that way (though I have known one or two developers who always blamed anyone but themselves, and particularly users, for errors.)
This works fine as long as the data flow is one directional. E.g. legacy backend -> db -> read-only frontend

However once the frontend and backend begin to mutate data, you're going to have problems doing that consistently; it's an anti-pattern I recommend against. Better to have an API handle everything.
I am a UX/UI designer, currently working as a freelanceer. Once I got inspired and wrote a somewhat lenghty reply to "Ask HN: how to find a good designer for a small project" [0].

Virtual Coachella is a hilarious take on a dystopian hellscape (not far from our present time). I love it. Like a Black Mirror episode, only condensed so that every single second is brilliant and packed with jokes.
This is not meant to be personally offensive. I normally wouldn't be this blunt, but I was one of the downvoters and you asked for feedback.

Your comment comes across as arrogant and ignorant. I have not formally studied quantum mechanics, but I do know theoretical physics is all about identifying and testing theories to better explain phenomenon. And the tests are statistically rigorous.

This is a thread specifically regarding an AI getting a wrong answer and practitioners suddenly deciding it's discovered new physics. Yet you claim CS is rigorous and quantum mechanics is not.

There is a tendency of someone well learned in one subject (eg CS) deciding that makes them an expert on any subject they casually observe. This is very off-putting.
You did nothing wrong

This is unintended and regrettable behavior, and we apologize

This is what the message should be. Maybe. I'd rather the software I use be apologetic than attempt to be my friend. That said, I'd settle for "we goofed, sorry" So it's not so much the tone (casual), but the content (own your defect, don't commiserate).

At the risk of a no-true-Scotsman argument, I want to point out the difference between Frequentism as practiced by statisticians and non-statisticians. Non-statisticians will simply say that a result was stat sig, without specifying even the corresponding p-value, let alone an effect size point estimate or confidence interval.

I always report confidence intervals front and center, and bring in point estimates and p values as supporting characters. And of course discussing to what extent the study design supports causal conclusions.
Unrelated, but it always amuses me how much Dutch sounds like drunk English ;-)
It sounds like they cater specifically to "the aural and visually impaired", but I can't figure out how?
It actually depends. I'm an emacs user and C-h will select the current 'paragraph', repeated C-h will select the next one down, repeatedly. Moving by paragraphs can be very quick. If you want that, it's almost instant.

Also C-u allows multiples of whatever you want. I can move say, 19 lines up with C-u C-u C-p C-u C-p C-n (move up 16 lines, move up 4 lines, move down one line) and it can be quicker than you'd think - there is a cost of moving your hand to and from the mouse/trackball.

If you know it's 19 lines exactly, C-u 1 9 C-p.

It can be quicker, depending. For precise selection down to the character where gross markers aren't present, yeah, I deffo go with the mouse.

I'm agreeing with you here, just adding a perspective.
> It would take real political will that simply isn't there.

Right. Instead, we (the UK) have two candidates that want to cut taxes for the individuals instead of making real change. BP has made 3x net profit compared to last year. ExxonMobil made 4x net profit compared to last year. Other energy companies have also raked in the profits. But yes, tax cuts will definitely help the poor, and not the rich!
I don't agree on this one.

The problem with frequentism and the null ritual is that it makes statistics easier (just do this one test, read this one number) and renders some kinds of mistakes somewhat harder (publishing a single false positive).

At the same time, it makes some bad mistakes much easier, most notably ignoring power, false positives, the garden of forking paths, type S errors and publication bias.

The inherent problem is that the null model is not what people assume it is, and the method (or at least the established canon of approaches) don't make you think about it.

If you use bayesian methods, you're pretty much forced to spend more time considering the effect size and credibility of your results, and you're basically required to report them.

This means that even non-competent bayesians probably have a better contribution to cumulative science.
These are the only examples I could find on a search:

> once you checked them

You can’t guarantee that you can check them, and that’s the problem.

I haven’t directly surveyed terminal support for the relevant OSC sequences (I wish someone would make a thorough terminal feature comparison—in theory terminfo databases would be part of this, but in practice the scheme is thoroughly broken), but from what I’ve heard I would expect a reasonably strong correlation between support for that and support for 24-bit colour. That is, you are unlikely to be able to check the colours on the very environments where you most need to.

As far as static checking of terminal capabilities is concerned, I think it’s reasonable to say that everything’s completely broken by design there too. Everything builds upon the idea of a $TERM variable being right and terminfo databases having relevant entries and matching reality, and they’re just not. $TERM will be missing or wrong extremely often, and terminfo databases are regularly out of date, and if you try to use a “correct” value for $TERM you’ll often find various software (especially old software, but even new stuff sometimes) falls over, normally in the direction of claiming that your terminal is incapable of doing something that it is actually capable of. This got to be such a problem that $COLORTERM was introduced, which is more likely to describe the true capabilities of your terminal, but still not quite always even if it’s there, and much important software doesn’t look at it either. If you’re familiar with web history, it’s a similar sort of issue to what happened in the User-Agent header, and for similar reasons.

So then, you’re left with maybe some notion of the terminal’s capabilities, and maybe the ability to find out what the colours actually are, but you can’t depend on either of these, and so you can’t in the general case depend on the values of any colours.
outlawing them would be silly but HOAs and city ordinances should not be allowed to force you to have a lawn
I know it was inline with expectations, but A 50bps move seems far too aggressive to me. I understand the risk of long-term inflation expectation moving higher and the need to contain them, but given recession is now the base-case it seems absolutely absurd to me to be overly worried about long-term inflation expectations.

There is nothing the BoE can do to directly address the supply-side inflationary pressures we're facing. What they should be focused on right now is where inflation expectations are likely going to be given their economic forecasts, and while those forecasts do suggest double-digit inflation numbers, they also suggest recession. While some monetary tightening was clearly needed, this has been a period of historically aggressive monetary tightening, to tackle inflation pressures that they have next to no control over, into a recessionary environment, during a time when people are struggling to pay their energy bills - let alone their mortgage and other repayments linked to interest rates.

If their transitory inflation call wasn't bad enough, they're now about to follow that with an even larger policy mistake which will push thousands of people into poverty, with many likely to lose their homes and jobs as a direct result of this move. Well, that's my opinion anyway. I think this 0.5% move after 5 consecutive 0.25% hikes given the economic risks is insane.
By "most" definitions, "most" means more than half. So we're literally arguing over a single person.
No, because "Show HN" has existed for a long time.
Yes, I'd actually prefer this.

BUT: The devil is in the details. How far will I need to travel to reset my email password? How diligent will the people be in verifying that I'm who I claim I am? How easy will it be to impersonate me and take over my account?

Personally, I think something like this needs to gravitate towards a government service.
I also don't like when it's framed as an "either-or" dichotomy.

It's like a programming language - there is no "best" one in general, you just have to learn how to choose the best tool for the job at hand, understanding each tool's strengths and weaknesses. It's not that mysterious.
Anyone else find it weird that there have been a flood of MIT links on the front page the past few days?
I recently ditched a bank for having this issue after I had to drive 700 miles to reset my password.

Maybe if that email service was run by usps or something I would consider it.

"Barely functional" in what sense?
Maybe not a startup, but I created a few android apps years ago. They were not very popular. They didn't have a flashy enough interface and marketing could have been better. I assume this sort of stuff extends to startups, specifically that you need to break through the noise.
I'm really nervous about any attempt to measure the value of HN in terms of money.

It could be that HN has made me a lot of money by giving me a place to relax and NOT think about money, allowing me to be more effective in the areas where I do make money.
Thanks, this is what I was trying to say but you did it better. :) Its fascinating things like Steel Mills which require a lot of heat are probably best located in deserts.
Some areas of space have a more matter than others e.g. galactic clusters, where the relative speed of the galaxies to each other is higher than the expansion. This video from the excellent Space Time series helps explain it: https://youtu.be/bUHZ2k9DYHY
Why not just use parentheses, because, you know, templates are just AOT-functions behind the scenes! Try to come up with an example where this syntax is worse than (angle or square) brackets...
Almost all modern Bayesian models rely heavily on simulation. This is mostly because it's a very effective way to do numerical integration, and almost all non-trivial Bayesian models involve integrals without closed form solutions.
Well, the "article" is mostly an opinion piece, it could as well be a Twitter thread. So, at least, there is some value when evaluating a personal opinion in the context of other opinions expressed publicly by the author. I'm not saying this is the case, but I don't think is invalid either.
Are you suggesting that the U.S. produces a proportionally similar volume of spam traffic as Russia, China, India, Vietnam?
>> Power semiconductors aren’t the most bleeding edge. SiC technology is a recent game changer leveling all market players to the same tech level.

IGBTs are not quite a commodity at highest specs, and power modules are yet another years-long development. Infineon has been building modules with high power density for decades and that experience will also carry over to SiC chips. Where I'm at we are building our own SiC "modules" from discrete components for now and these are much larger than Infineon power modules - but we are air cooled ;-)

It seems like there should be a standard form factor for 3-phase power modules by now. That would make them easy to replace even if you have different specs.
As a Canadian that's not really how I see it. I worked for a bit in California and while I was earning more than I do now, the cost of living was probably double what I have right now so the math really wasn't as simple as "move to the US to make more money".
Costco is for people who's main activity outside work is spending money. It saves those compulsive spenders some money and makes them feel better about their problem.
Leaf blowers are the last frontier of regulatory internal combustion engine efficiency. Your car is required by law to travel 100 miles on a drop of 10% ethanol fuel with minimal smog release. Your leaf blower can be powered by funeral home soot for all the EPA cares, and you can run it full blast right outside little Timmy’s window all afternoon. This was a win for both noise and air pollution, which we should be clear kills many more people per year than the costs borne by landscapers to upgrade to electric machines.
I’d wholeheartedly disagree, some citizens were receiving $2-3k a month from having dependents in areas where that would cover 2 entire families bills. This in turn created massive free cash flow, which was then mostly spent.
I’m generally curious after reading this, what effect does our molten core have on our ambient surface temperature? I can’t imagine much, but it can’t be nil, and I genuinely have no idea.
Martial Arts. Brazilian Jiu-Jitsu and Muay Thai are popular enough that they allow me to snap into a community wherever I go and interact with people outside of my work circle.
Well, there's more transfer than nothing, but the hard parts of digital (sophisticated logic, absurd per-gate reliability, low feature sizes) just don't overlap much with the hard parts of analog, which is all about device physics and materials.

Sure, the people who design logic transistors would probably adapt quickly to designing power transistors, but they are a very small part of a very large machine. For example: a digital organization may have learned through harsh and repeated lessons 100 subtle ways to be more conservative about device changes. FinFETs took 15 years to go from R&D to prod, for example. While this level of risk aversion might be critical for shipping billion-transistor devices, it may be maladaptive for shipping single transistors, where a 15 year deployment leaves you 10 years behind your competition.

Likewise, the processes (patterning, etching, implantation, etc) are largely similar, but the digital side has made colossal investments optimizing for things that just don't matter as much for analog design. The famed EUV machines? What does a power transistor gain from tiny features? I'd be surprised if they were useful, let alone useful enough to justify the cost, let alone useful enough to justify the cost and the risk of repurposing a machine for process innovation. Like using a F1 car to commute to work -- even if cost were no object, extreme optimization for one purpose makes it worse at others.
