> If you compile code on a machine with SSE or AVX and run it on an old Pentium, does it crash?

Yes. Or it leaves them unused on the machine with avx.

For short runs of instructions, the overhead of fallback selection is larger than the overhead of using the least common denominator. For large functions, fallback selection is done by selecting specific functions after benchmarking.

Unlikely. I think 10%+ changes in speed are much more dangerous than a 1% higher speed overall.
You are welcome to advocate for pleasant, humane prisons. Run whatever antirecidivism campaigns you wish there. If they work, that's great.

In either case: send people who commit crime to those prisons. If they do it again, send them back.
> But I'm not sure how they explain the refresh during birth/zygote formation.

Probably it's just survivorship bias. When a organism has trillions of cells, it can afford to have some fraction of them damaged. It just carries on with degraded function. When it has a single cell, all essential genes must be functional, or it dies before anyone knows there was a pregnancy. It's a bottleneck. The zygotes that made it to birth are the ones lucky enough to receive a minimally viable set of undamaged genes from both parents. Most couples try a lot before one successfull pregnancy.
In some way, you can view crypto and going from. Ron Rivest monoculture(RSA, RC4, MD5) to a DJB monoculture. Meanwhile the NIST seems intent on a Joan Daemen monoculture ( AES, SHA-3)
I do agree that animation, when used, should be a deliberate and thoughtful choice. Sometimes animations are helpful to show a connection between two things, illustrate change or show contrast. A designer should have always ask, what value does animation add here? How does it strengthen communication and understanding? Animation can be a great tool when appropriate but shouldn’t just be a mindless default.

I read through the thread and his tweets.

He's saying that he doesn't read the business plan, balance sheet or the pitch deck. He just asks them questions, answering which would answer everything in those documents.

So, basically, in addition to writing all these things, you have to read it out to him because Mr. rich guy investor doesn't want to read it himself.
No official statistics anywhere, and the only experts interviewed are all consultants for the retail sector. It’s basically a press release.
RISC-V is going to bite at the low end embedded market where pennies matter, but it'll be a while before it eats into ARM at the mid to high end. ARM is offering non-discriminatory licenses at unit prices that are largely an irrelevance on the retail cost of a mobile phone or laptop. So it's going to take a long time to convince manufacturers that they want a non-compatible chip versus a few cents extra to get the well known one with all the support.
I actually grew really frustrated with existing solutions for organising notes:

- Almost all solutions that attempt to take seriously the concept of knowledge graphs are Software-as-a-Service. Ouch. They say you should “build a second brain”. I certainly don’t fancy the fate of my second brain (whatever that may be) to depend on the commercial success of some company.

- All existing editors, even the web-based ones, have some hangover from file-based content management. Even with ability to cross-link to nodes inside a tree structure within files, the rigidity of file boundaries is still over-constraining, especially when one is trying to grapple with unfamiliar concepts during which the structure and links are constantly shifting.

- The maths-authoring abilities (i.e. facilities to edit LaTeX formulae) at best look like an afterthought. Writing anything more complicated than Maxwell’s equations is painful.

Out of desperation I decided to roll my own. I set out the following desiderata:

- It should take the concept of knowledge graph as far as possible. The foremost thing is to do away with files, and promote vertices (nodes) and links (relationships) to first-class status.

- While upholding the previous principle, it should make editing as natural as possible, preferably confirming to existing text-editing habits. The experience should definitely not be like creating nodes and linking them together inside graph databases: slow and confusing.

- It must work without an Internet connection. Or better: it should not make any attempt to connect to the Internet at all.

- It must not be too heavy-weight, and data should be easy to back up. This precludes any JVM-related stuff, docker images, or spinning up Postgres/Neo4j/Datomic/what-have-you just to write some notes on a local machine.

- It should cater for the needs of heavy maths editing.

Now I have been using my own app, powered by sqlite for storage engine and ProseMirror for frontend, for quite some time, and I am really satisfied (hard not to be satisfied by your own work though). It is becoming increasingly polished (full-text search anywhere, very fancy query, loops in the graph, etc.) but I hesitate to open-source it, because as far as I know maintaining open-source projects can be really time-consuming, especially when people actually start using them.

Yes you're right of course.
Can the US Accuse any of Violating the ‘Rules Based International Order’?
> What are some low-stress jobs that pay well?

It probably depends on what you're used to and how you handle stress.

I'm a web developer and find it incredibly low-stress in comparison to my previous lives. No back-to-back double shifts, no risk of working a full day and not getting paid for it, no abusive management, no rampant substance abuse at work, no "if you have time to lean, you have time to clean", no pressure to come into work when you're sick, no getting written up or even fired for being <5minutes late to work, no punitive scheduling... I could go on.

I see people complaining about the software industry and I really don't get it. This shit is so comfortable, easy and straightforward in comparison to the kind of work most people have to do.
A significant percentage of kids are also hampered in their development while growing up by abuse, miseducation or neglect, so they may need even more time to recover from this and 'find their footing'. Many 25 year olds are still processing childhood trauma and playing catch up with their less disadvantaged peers.

My company essentially does that and I find it incredibly annoying. It breaks many stuff and makes performance much worst. Just so they can more easily spy on us.
Oh come one what could possibly go wrong? We'll just store the specimen over there, right next to our synthetic samples of vaccine-evading COVID-19.
Uh, I meant it the opposite way :) Unaliving yourself at 90 is a personal choice which I of course support, but I'm mostly talking about making sure we can live healthy lives over the current limit.
The psychological issue is that even though we as individuals cling to life (sometimes too much), trying to rouse support for life extension sometimes feels like urinating in public.
No, because the limit isn't driving time, it is things they wany to do. Induced demand is people who can finally do something better. The only time you are right is when you are so far behind that people who used to stay home pick a second best thing because what they really want still isn't in their time tolerance.

Note that building roads is in general not the rigjt answer, build good transit so they don't drive is much cheaper in the long run.
That's an excellent point! If you want to make that work in your favor you need to have the dd-wrt website open in one tab and ebay open in another.

The AC section is more of a good starting point than anything definitive.
You can use the following for CRUD app:

It is not useless, because there is information that the browser has and that it is trusted to protect. Consider a server that returns JSON in response to a POST request, and what JSON it returns depends on the user's cookie. Properly configured CORS headers allow the JSON to be read by some origins and not others.

An attacker with curl will not have the user's cookie and an attacker with a malicious website will not have the right origin.

The bones from old burial sites up to and including the Middle Ages indicate that most people didn't live into their 60s. Not even those who reached 30 in good health.

There always are old adults present, but they are rare.

From your nickname, I gather you are a Czech. I can link an article about analysis of an early medieval cemetery in Rajhradice to you. 244 buried people, 220 skeletons were successfully analyzed for age. No one over 60, eight people over fifty (almost all women).

> In a web-application you are NECESSARILY breaking, in all but the most exotic cases, the "multiple programming/scripting languages to learn" AND "external dependencies" requirement. Almost always, the "simple and resilient, can last for a long time" requirement goes out the window as well.

No? PHP web CRUD apps from a decade ago still work ( some updates are required for security issues, but still), have little to no external dependencies ( you need a webserver like Apache or PHP-FPM to serve your PHP, but that's it), and are in one programming/scripting language - PHP, with some markup in HTML. Nobody is forcing nobody to use JavaScript, that's only if you want and need client side dynamic content. Alternatively, node.js allows you to use JS client and server side, and it can last a long time. However, you need some dependencies.
Ah, thanks, I had not heard this term before!

I do think it has its place for some things but it’s just very badly done here for no real purpose.

More like German political corruption that guarantees telecoms' monopolies to milk customers with expensive shitty offers, rather than a free market with healthy competition like in Eastern Europe.

Also, didn't some German politician say "There's no way to make money with the internet so why bother with infrastructure investments?" LMAO
I must say as a non expert on the topic, i don't understand the downvotes. I wish people who downvoted would take a moment and explain what they disliked
You’ll have trouble shipping that extension. Not because it conflicts with AVX2, but because Intel will sue you for your comparability with the rest of x86.
Favorite Note Taking Tool
I just read the article "the fall of roam" here on HN. The author talks about abandoning the ROAM app- I abandoned it after an hour of use. Question; whats your favorite way to take notes- and how often do you revisit them?
Seeing and hearing prairie dogs squeak at each other is one of the neatest things I've encountered at any of the national parks. At Theodore Roosevelt there are large colonies bisected by a park road with plenty of pulloffs. I sat there in the truck with my dog for hours just watching how they scurry around and play in the 20 degree temperatures. Seeing the panic when a badger started to encroach on their territory was also kind of nerve-racking.

I feel some devs want low effort easy tasks to do, to give the impression of getting things done for KPI hunting.

Otherwise why put in more work into removing something than its presense will ever generate.

Like when Python removed support for Windows 7 for no good reason at all but it being past LTS. But there was a submit ...
The scarcity is driven by land being untaxed. There is very little cost any more to treating property as a bitcoin-like store of wealth. This is partly why there 1.5 million empty homes - 3x the number of homeless.

China has a similar problem which is why it has ghost cities - thats where the hoarding instinct channeled wealth.

Zoning laws are a red herring. They're the worst enemy of the property developer building yet more luxury condos to be shoved into a hedge fund's real estate portfolio but they dont address the underlying cause of not enough property.

We hear about it a lot because property developers have lots of money a significant financial incentive to drive public opinion, but that doesnt make it true.

Drive up either property taxes or institute a land value tax and the instinct to hoard property as a bitcoin like store of wealth will collapse, freeing up land for real people to live on.
Bravo, best self-own I've seen in a while. And thanks for letting us know you're the kind of poster who unironically echoes white supremacist talking points.

Show HN: Python REPL with auto-import and auto-reload on changes
As someone quite deeply into the "tools for thought" thing... I hardly ever worry about the meta-task. I just make notes tied in to one or other index page, all of which (there are only a few more than a dozen or so) tie into a higher-level index page. Given the search capabilities of a decent personal-wiki-like there's not really much call to arrange, file, tag, classify notes.

I use Zim Desktop for my notes because it's simple and (precisely) because it stays the hell out of my way and lets me focus on my own writing. Over several years of doing this I've tried quite a few other tools, but none manages to hit the sweet-spot of simplicity and affordance I find in Zim. Roam, Notion and other web-based tools are just a fucking annoyance to me, being clunky to use and offering little since I have no need to access my notes across multiple devices, nor any use for publishing/"sharing" my personal notebook or pages with others. If I do want to do that I can (and do) just copy the relevant material over to my (static) blog, `git push` and the job's done.

(Edit to add: the "Backlinks" plugin is vital for using Zim for this purpose.)

Music/video is much more challenging in that regard: our computers' capabilities for searching those is pitiful, but then... keeping bookmarks to such stuff is hardly the use-case for a personal-note tool. It's for keeping your own thoughts and observations, not for bookmarking random blatherings.

I did not want to punch the easy target with digital infrastructure.

Our 100 MBit includes satellite TV and telephone flatrate for 30 € per month. Still not in the range of other countries, but at least significantly cheaper than the big players in Germany.

It is provided by our municipal telephone, gas, electricity provider. With really good customer service thrown in (compared to the crap of the big corporations at least)
https://man7.org/linux/man-pages/man2/membarrier.2.html provides a good example of when a processor memory barrier is eliminated but a compiler memory barrier is still required.
If we choose to value everything we touch by way of "the next highest bidder might have paid $X for this" while fully ignoring their intentions (and so allowing black market sales to be in scope for the implied auction), I think you won't actually enjoy the society you end up with :(. Like, as a security researcher yourself, it might feel interesting to posit the exact addition of value we protect per incident, but I think the ramifications on how other work gets valued as well as what adverse side effects result from this mental model are scary.

It is thereby really only "required" (for the world to function) that there is sufficient monetary motivation for people who don't want to spend the rest of their life feeling either the guilt or stress (even if merely due to the ramifications of people finding out) of having done something "wrong" (which I put in quotes as I feel the "code is law" argument that can result at this point isn't actually that useful in a discussion of morality) to bother to then go out of their way to help (as opposed to not searching hard in the first place, looking the other way instead of reporting, or merely hoarding the bug as a parlor trick).

And so like, while I totally see how this bug could easily be worth at least tens of millions of dollars to someone, it isn't clear to me that finding and reporting this bug should imply that I would need to be paid (and "by who?" is a then a hard question to answer even if we think this, one which might bleed into "and how?" a bit as the first answer is probably awkwardly decentralized in scope) the tens (or even hundreds) of millions of dollars that that hypothetical black hat might have figured out how to extract (which I make a bit theoretical as profiting from crypto hacks is harder than people often assume, something I touch on in my article; I think you might have to go for extortion, and even that didn't work for the Wormhole hacker)... most people simply aren't of the moral constitution to be black hats (which is probably a good thing).

(In this case, the main lingering ethics question related to this bounty that I come back to occasionally is that there are projects--such as Metis--that forked Optimism and now compete with it using Optimism's own code and vision... projects that (in the case of Metis) are actually of similar size to it (based on "total value locked", which is imprecise but probably the best measure here for potential impact: Defi Llama lists Optimism at $344M and Metis at $347M) which are still relying on Optimism to motivate the security efforts for their platform... it feels at least awkward to me that they should get a "free pass" here simply because their listed bounties were lower than Optimism's? Like, even if you don't think I should get money from them, maybe they should be helping compensate Optimism?)
It’s a time saver, if people don’t have a good answer to a question they are likely to write a lot of info which doesn’t answer the question.

In conversation you can pick up the BS a bit more readily than in a document.
I would argue that this is far more complex than he being lazy. A slide deck or any document is well curated, optimized and spin'ed in a way that the creator wants it. Same reason why I actually prefer to write meeting minutes.

He does what anyone sane would do: ask the question and get real reactions. Most people are much better in lying (aka optimizing) on documents than in real life.
In past threads I’ve heard about exploit brokers and how their rates are typically much higher than bug bounties. If Hacker News commenters know about these avenues I’m sure bug hunters can find ways to cash out for more money. Calling it unclean is stupid anyways, since the company clearly isn’t paying enough for bugs in their own service…this is the same kind of thinking that leads to “responsible disclosure” and all that junk.
I remember reading a book (Protector, by Larry Niven[0]), in which the protagonist (a "proto-Belter"), eats a sweet potato, turns into an ugly-ass duck, and lives forever.

After about 25,000 years or so, his brain becomes "full," and he can't remember stuff, anymore.

I'm not sure how much you know about YC's history or PG's approach to investing, but in this and your other comment in this thread, you seem to be under a misapprehension.

The types of companies PG has normally invested in were barely even companies yet. They were small teams with an idea. Maybe a prototype. Maybe a few users. Often they were not incorporated as companies when he agreed to invest, or if they were, they weren't old enough to have audited financial statements. He didn't do "due diligence" as there was nothing to do diligence on; pretty much everything to know about the company was sitting in front of him.

Did he have to have a good bullshit detector? Yes, absolutely. But that was a skill he and the YC partners learned from doing thousands of interviews over many years. But also, it didn't matter if a few dud companies slipped through; they were investing such small amounts it didn't matter. That's the whole point of YC.

In another comment you wrote "at the scale of PG's investments...". That's what says to me you're misunderstanding things. PG's investments have always been very small. He just did many of them.
If I'm doing any sort of streaming (video chunks, etc.), then I'd want sequential pipelining for an optimal experience.
What amtm scripts do you use?
Surely someone with the skills to find bugs like these would be an expert in cashing out on those bugs?
Seems both articles are wrong - but the real issue it gets correct is:

you should never hard-code an API key in this manner.
Most people don't understand this stuff so they'll take it at face value even though it's likely a scam
