> The received wisdom is that the only safe fork is the one followed immediately by an exec(e,l,p,v). If you can't exec(), then keep your design as simple as possible, consult your OS manual, and address your failure modes.

But this is not true at all, calling any async safe function is save, including exec, which is simply an async safe function.

Furthermore, Rust's standard librarty does not even expose exec directly, but does expose a function to call arbitrary code before exec, but this function is marked as unsafe and the only documentation is that “care must be taken”.

For instance, socket activation in the launchd style that systemd and stocketd use must execute various socket related operations after forking, and before exec, these operations are async safe, and thus it is possible to do this from a multithreaded program, but in Rust there are no guarantees whether various functions dealing with sockets are async safe. They might call malloc or use mutexes internally; one has no idea.

> Asking any compiler to prove that your program's fork() is safe is asking an awful lot.

I'm not asking that at all, but it's actually not difficult at all. All it needs is a trait for async safety on functions, and any function that is marked as async safe can only call other functions internally that are. That is all it takes to do it savely.

But I'm not asking for a compiler proof; I'm simply asking that Rust document which functions are async safe and which are not, so that programmers can do it in unsafe code.

> Ada was another language designed with safety in mind. They chose to shove fork() into an "Unsafe POSIX Primitives" package -- in other words, use these at your own risk. I think this was a good call.

And they document what functions are async safe; Rust has no documentation nor guarantees about this.
I went through the same process. Acton gave them a huge foundational base, but you want it to be a viable model in its own right.
Thanks, that definitely wasn't in my mind when I looked at the original diagram and instantly pictured the quadrilateral base that makes "possible".
I do agree that it's relatively new, but not _that_ new. I feel like it's been around for at least a couple of years (but my sense of time since the COVID pandemic started has been unreliable).

FWIW: Yarn has had lock files for a longer time. I know it's not technically npm, but they share the ecosystem.
Are you in the US? Because even if I wanted to walk/bus to the grocery store near me it would take almost 4x longer one-way (46 mins vs 12) and I’d also be subject to the maybe-once-per-hour schedule of the bus.
Almost.

Those bookmarks are more or less the tip of the iceberg. And they were almost all created during $DAYJOB which was years ago. Although already then (~2017) i had about 3500 sources in my RSS Server. And of course, I lost track of everything remotely interesting.

Archiving those links was fundamental work for creating my news blog, which is still run privately until I figure out how to implement a community communication system (mostly commenting) that will work on an IPFS backend. I mean, the comment section of HN is what has made me come to this site for years.
How did she do it? (2008)
non-paywalled summary?
The entire reason I didn't apply last season was because despite being my startup looking for funding, and despite us having our best traction to date (functional MVP deployed in big retail partner, making sales) - the $125k (minus the cost of uprooting our team and product to CA) was just a bad deal. We've been in talks with some angel groups with 500K being the ask for the pre-seed, and that has been well received. So I think 500K is right on the money for now. It's a good change to see!
Chiming in on the weak labeling question: As of right now, you can use outside libraries like skweak to create weak labels offline and then PUT those using our API (https://www.nyckel.com/docs#update-annotation). This wouldn't cost anything since we only charge for invokes, but it requires some work.

We may look at adding weak labeling as a first class feature of our site down the road, but we are not yet sure we need to. With the powerful semantic representations offered by the latest deep nets, we find that smaller number of hand-annotated samples often suffice for the desired accuracy which makes the whole annotation process simpler and faster. Of course, if you have data & evidence to the contrary, we'd love to take a look.
They don't retool the factory every 5 years... I think you're underestimating things a bit.

If the top triangle is not parallel to the base (which you picture by your method), then the two triangles don't match, even in a real picture.
I can’t give specific advice based on what you wrote, not knowing you or your abilities. I can’t imagine not knowing how to code without a partner. Your post and comment communicate lack of confidence in yourself, so you may need a mentor or a manager who can break tasks down for you and supervise and review your work.
I've been to this guys place. Nicest guy. But he is absolutely surrounded by "Trump Nation" people (their flags are everywhere out there) who hate him. Every time he leaves home his place is vandalized. Just before I visited someone had waited till he was gone and then dumped truck loads of some kind of poison all over his grounds. He was going through and sifting it out of the soil by hand. It is incredible how cheerful and optimistic he remains in the face of all the surrounding hate. I'd definitely recommend going and visiting his place if you are ever in Portland.
In the case of the spotted lantern fly, it's just the cost of global trade. It was not intentionally introduced like the Bradford pear.
Keep doing boosters every N months and the risk of myocarditis will eventually be greater than Covid.

There’s an abundance of supply of people with masters degrees in machine learning? How’s that possible? I thought this shit was supposed to be hard.

Has humanity just scaled way too hard or something, because if we’re having an abundance of supply in difficult cutting edge fields to the point where they also have their own version of Leetcode, then what hope do average people have of getting any job in this world?

Or, is it at all possible that companies are disrespecting the candidate pool by being stingy and picky?

Maybe the truth is gray.
Let me tell you what it brings: independence. I've lived through an abusive relationship where I was almost murdered, and I am thankful every day that I had a career to keep me alive after I escaped from my abuser.
Maybe cost? Those things ain't cheap.
I've also wanted a better shell scripting experience, and have bashed [no pun intended] my head against this several times. I think some of the major pain points that resist adoption of a language like Python or Ruby for in-line shell scripting or simple automation is:

* These languages prefer to operate on structured data. If it parses from json, you have a much easier time. But, most commands you'd invoke from the shell emit unstructured text by default. You can deal with this, but it's a pain point, and it means any serious scripting starts off with a "here's how you parse the output of <foo>", and several rounds of debugging.

* The shell's first and foremost usage is a user-facing interactive interface to the computer. Most of what you do is invoking other programs and seeing their output, and doing this is very easy. While python & ruby have REPLs, these are mostly focused on trying out language features or testing code, not invoking other programs, nor navigating a file tree. A lot of shell scripts start as 1-liners that grow and grow.

* Invoking other programs: In sh, invoking other programs is the primary activity, and it's relatively straightforward - you type the name of that program, press enter, and hope that it's on your path. In Python or Ruby, it requires importing the proper library, choosing the correct command, wrapping it and arguments, and ensuring everything escaped correctly. [Ruby _does_ have the backticks operator, which does actually make a lot of 1-off scripts easy, but this is not a panacea]

* In sh, a lot of the 'utility' programs like cut, sed, awk, grep, head, tail, etc., are standing in for the capabilities of the language itself. In pure Python or Ruby, you'd do these kinds of things with language built-ins. But, that's a learning curve, and perhaps a bit more error-prone than "| head".

* On top of all that, yes, momentum. If tomorrow you showed me a shell replacement for nix that was unambiguously* improved in every way, had excellent documentation, community support, and was actually pre-installed on every machine, it would still take a decade or more before it was really a default.

-----

I want it to happen, so I'd never discourage anyone from taking a swing. IMO, some of the top-level considerations that are necessary for making a successful sh alternative are:

* minimize the additional # of characters required to invoke a program with arguments, compared to bash.

* Decide which suite of typical utilities should actually be built-ins (i.e., things like cd, ls, cp, grep, curl), and make those standard library, built-in, without additional import or namespacing.

* Focus on an append-style workflow. Functional programing styles can kind of help here. Wrapping things in loops or blocks is a point of friction.

* An additional highly-desired feature which just isn't in sh by default, to overcome momentum. I have no idea what this would be. More reliability and better workflow are _nice_, but sh is sticky.
You write a lot of words to explain how the maintainer could justify his malice. At the end of the day it's still done out of malice, though.

Unless he's gone absolutely bonkers, he's doing this to intentionally cause damage. The reason for it does not matter, as the definition you posted helpfully points out.
Everyone's got their own personal tolerances and limits. Did you read the blog post? Sounds like OP was having a pretty bad time.
Yes, that could also be helpful to split a complicated build graph into more manageable pieces. I had a look at the tools available for an unrelated project a while ago; I probably need to see what’s available now. Hopefully the tools have progressed a bit.
Exactly, carriers really don't want anything that helps push net neutrality in any real way. They don't want to be commoditized to where it's just pipe for Internet data to transmit through as you mentioned.
Well Virtue with a capital 'V' is one big one! And of course they're an excellent source of revenue for Pfizer et al. You wouldn't want to risk it would you?

-- writing this while my toddler is banished from daycare for 10 days because a single kid there tested positive.
I know all my children under the age of 4 (3 of them) are able to receive a flu vaccine though. I would assume quite a few parents are doing the same. So not quite apples to apples. That being said the risk to children that age for COVID is quite low, and I would not be shutting down schools or even forcing masks. Those are important to development of children especially since it disproportionally affects low income children. So I agree that the risk of COVID to children is small, and extreme measures should not be taken. My only issue was comparing two things that probably cannot fairly be compared.
The data suggests:

Young males with history of heart arrhythmia should be vaxxed.

90% of pregnant women should be not be vaxxed.
I understand that most people just wait for their peers to switch to EV first and they'll only make the move when >X persons around them place an order and confirm from experience that EVs are the way to go. They avoid taking risk with what appears to be "unproven" technology that happens to cost a significant % of their household's wealth.

I've never owned (or needed a car) so I can't speak for myself, but my family and friends are 100% convinced that BEV are the future, and they also have the means to buy one now. They just tell themselves that they must wait for their neighbors to buy an EV first and hear first hand that charging is indeed not an issue before making the switch. It's a chicken or the egg problem and in the meantime, they're fine with purchasing plugins (even though they know it's a worse choice and that the plugin will depreciate faster)

Most people are simply risk-averse and they are enough early-adopters queuing for a Tesla delivery. So EV adoption can't go faster than Tesla can build factories and pump out cars. The early majority will follow suit.
If pigs (or any animal) broaden the compatibility to other organs, what are the ethical implications for raising them with the intention to harvest their organs, if any?

On one hand, we already raise pigs to kill and eat routinely, and (mostly) people don't care - is this any different than say, buying a pig heart at the market to eat?

On the other hand, it does somehow feel different to me, perhaps because sharing organs somehow humanizes the pigs by emphasizing our similarity? I'm not entirely sure from where my hesitation stems.

I'm curious if anyone else read this story with mixed reactions.
One word: 3D printing. Ok that was two words, but still exciting.
It broke a ton of other people’s projects, on purpose. You can argue that he could have done much worse — say exfiltrating all of the AWS credentials from CDK users – but there’s no definition where it’s not an abuse of trust to sabotage your users.

1. Tests should not be published

2. You can update the test script with the release too: "test": "echo pass"
This is a very wise answer.
The claim that they're doing so to "limit student financial aid" doesn't make sense: how are they going to raise tuition and fees to $100K/year without increasing student loans?
OP's link supports their numbers for NY state: 95% of 18+ year olds have 1 shot, 83.4% of 18+ year olds have completed vaccine series.
I'm quite happy these places makes it so clear they're not places I would be happy to work. I always ask about the interview process and tell the recruiters I'm not interested if they expect really lengthy processes. I'm fine with things dragging out of they have additional questions after initial interviews, but not if their default starting position is that they need that.
I'm not in the US, but I didn't know the US was quite that bad. Can't you cycle?
Agreed - at that level you're talking nearly 100M for each employee? Maybe more?

Even if I'm off by a magnitude (and I think I'm not) - that's life changing money for everyone that helped him build Whatsapp.
This is not our first rodeo with vaccines. So we do in fact have excellent reasons to believe they don't cause delayed long term effects. That is, if there were long term effects, they would manifest themselves in short order. There's no biological mechanism for a vaccine to lurk in hiding for years and then suddenly cause a brain tumor or chronic inflammation or what have you.

"When new vaccines are released, the unknown side effects, if any, show up within two months of vaccination. This history goes back to at least the 1960s with the oral polio vaccine and examples continue through today." [0]

"First, when these [delayed side effect] events occurred, the onset was within eight weeks of receipt of the vaccine. Second, in all of these cases, except narcolepsy following H1N1 vaccine, the side effect of the vaccine was something that could be caused by the infection, meaning that getting infected with the virus also carried a risk of experiencing these outcomes. " [1]

"Forget adverse effects over five or ten years: the way your immune system works does not allow for such long-term safety concerns." [2]

The more varieties of coronavirii that we encounter, the more our immune system will build a broad-spectrum response to that "class" of virus. To be clear, I am not saying that the coronavirus is going to disappear. I'm saying that it will become closer to a common cold over time.
What, so now displaying an error message means you're responsible for the error? See some of the other threads about why Apple might not like playing dirty to go behind T-Mobile's back--each one needs the other for its good reputation.
You're right, sorry I have misread this then. According to Wikipedia, MobileCoin uses its own blockchain based on mechanics from Stellar and Monero [0]. That also makes a lot more sense technically, and explains the supposed 4 years of development [1].

I was also distracted by the fact that you can't (usually) hear the difference between English words written with one 'l' and those with two consecutive 'l's.

"Voksal" and "Vauxhall" seem like they should each have six phonemes.
There is Opel Corsa-e, its brother Peugeot e-208, there is VW e-Golf, Renault Zoe (a bestseller). The problem is they are much too expensive for their segment. So manufacturers try to make those fancy cars, because the price is easier to swallow. It will change, but cars in general will get more expensive. Maybe within 10 years it will get to some sensible stabilization.
Isn't that about coffee not caffeine? I don't see how what caffeine alone does could be in any way helpful, outside of as a pure performance enhancer for very specific situations.
No one will be able to avoid exposure. Measures like social distancing and masks aren't sustainable, and they're not completely effective either. Fortunately the vaccines and other treatments are very effective at preventing deaths.

Is "language for connecting adults" an autocorrect of "language for consenting adults"?
I love the taste of coffee. Unfortunately I can't drink it as I get a near euphoric high followed by unpleasant hyperactivity and weird anxiety. Seriously. It's so unpleasantly strong for me. Tea I can drink but I don't touch it during work hours.my problem is having too much energy so I drink a lot of red bush tea during work hours. It's very calming.
I don't think it is all that uncommon for regular human-to-human transplant recipients to be on immunosuppressants for life. If I'm not mistaken, that's the case for all organ recipients, but there may be exceptions. I think the concept of "immunocompatibility" can refer to a spectrum of outcomes that we haven't gotten down even for transplants within our own species.
In that case, you could just skip the grid and put the turbine in the car.[1]

Yes, the vehicle is heavier (=less efficient) when you carry the range extender around with you, but that's compensated for by not needing as heavy a battery. Eliminates dependence on the grid; replaces it with dependence on the current refuelling infrastructure. Which latter, at the moment and in most places, certainly is better than the currently available EV charging infrastructure. Crossover point where pure EVs become more efficient TBD by how fast fuel infra is reduced and how fast charging infra is improved... With an additional confounding factor introduced by GP's hypothesized grid instability.

Correct data is the foundation for making an informed decision.

In this case the actual hospitalizations have been inaccurate, so that very important decisions have been made on inaccurate data.

The real problem in Denmark is the inability to maintain the same hospital capacity as just 12 months ago.

It feels a bit too convenient that the inaccurate numbers support more lockdown and restrictions.

The new and accurate numbers for hospitalizations will hopefully lead to serious reform of the health care system, it is sorely needed.
Your implicit claim is that NFTs offer nothing more than decentralization which is not true, as it's basis is a public tamper resistant ledger that is difficult to censor. How many systems like this exist already? How many are easier to use than NFTs? How many of your prospective customers are likely to know about or want to use this alternate system versus NFTs?

To claim it has no benefits other than decentralization seems odd to me

I just want to add, colors is pretty poorly designed package.

It modifies the prototype of String! This is a well known anti-pattern (yes, there's a safe mode you can opt into but it shouldn't have the first mode at all)

It also has a ridiculous "theme" feature that can be replaced by the same amount of standard JS. Meaning you gain nothing by using the theme feature that you couldn't do yourself except you make your code more dependent and more likely to break/need updating/etc since you added more dependencies to achieve something where none was needed.

It does tries to do too much by auto detecting whether or not to emit colors and provides no way to tell it what you actually want (since it's guess may be wrong)
Vaccines still lower disease severity.

Also vaccines reduce risk of some post-acute COVID disorders like MIS-C (which can result even from asymptomatic COVID).
