Not exclusively. ARM's roadmap is driven by what all of their customers want, not just Nvidia.

There doesn't appear to be sufficient profit margin in the industry for too many greenfield, non-reference custom implementations.

So if Nvidia-ARM sticks out a reference implementation or architecture choice that's beneficial to Nvidia, there's limited capability for others (Apple, Cavium/Marvell, Qualcomm, & Samsung?) to strike their own path, and they'll certainly be paying steeply to do so.
Not saying to disregard risk. Of course the cost vs benefit analysis have to be done.

University press releases tend to be better, although they're clearly promotional. The trouble with most scientific papers is that they're highly specialized and, depending on the field, hard for outsiders to read. In those cases we usually recommend submitting the best third-party article and linking to the paper from the comments.

A similar category is legal rulings, which came up yesterday: https://news.ycombinator.com/item?id=24357078
> I'd also like to point out that road wear is approximately proportional to the cube (^3) of the weight per axle on a vehicle, so cars are probably responsible for a minority of this pollution.

Could you clarify that a bit? Do you mean that the friction of the tires on the road releases nasty emissions?

It's important to note that, in America, any police enforcement comes with a chance of death or injury. When we make little laws (jaywalking or whatnot), we should be careful to keep this in mind.

None of what you've said actually matters. Again, the standard isn't that you need to be correct, but that the statements you make would be made by a reasonable person. They can all be ultimatelywrong as long as they aren't unreasonable.

It isn't unreasonable to call someone who shot someone else a murderer. It just is not.

It is not unreasonable to conclude that someone who travelled to another state and then shot someone was doing so for nefarious reasons. It may be wrong, but it isn't unresonable.

> This "evidence" came into existence after the claims were already circulating

I'm not saying that using the Wikipedia article is evidence for the claim. I'm saying that the claim cannot be unreasonable if wikipedia ultimately reached the same conclusion.

Again, you don't need to cite someone else to be not defamatory. As long as the statement, standing alone, isn't unreasonable, you're good.

> None of these reports, at least that I've been able to find, show all of the video evidence that is public thus far.

That doesn't make them defamatory.

> Not exactly. I'm saying that Elon Musk is one individual who has no following because of his 'investigative journalism' credentials.

Your original complaint was about random individuals in twitter mobs making defamatory statements. They also have no credentials. So are you now saying that actually all the random people on Twitter are fine, but it's CNN and NBC and the news organizations that are making defamatory claims?

Because that's a reach. You really think you know defamation better than the lawyers who work for those companies and specialize in defamation?
If the client app is open source and the messaging is end-to-end encrypted, I would say it's a lot better than being completely closed. The encryption, which you should now be able to verify, means you don't have to trust the server with your message data.

Though, sure, it would be better for the server software to be open source and rehostable too.

From TFA:

"Dewar personally told me that when implementing the GNAT compiler, whenever they looked at the language specification and thought it might be complicated to implement, they assumed they didn’t understand the language specification and looked for a simpler way to do it. This mindset that “there is probably an easy way to do this” seems to have been different from others, who seemed to assume that complexity was always an inevitable part of the job."

I've been on the losing side of this battle my entire career. While I thought striving for simplicity was core to the job, it's only harmed me. Though it's nice to read about another person who apparently thinks like me.

For heat pumps more outdoor units is definitely more efficient, since the outdoor unit needs to be big enough to accommodate all connected indoor units at once, and will be on even if only one is in use. Two per unit is my go to trade off on that one, with an attempt to group together units that are more likely to be used at the same time (so no bedroom / living room split, try to stick with bedroom/bedroom and living room/dining room etc).

BTW they have low profile indoor units that can be embedded flush with the ceiling or wall, so the bulkiness indoors is not even required anymore.

Wiki says that "Hydroxychloroquine is being studied to prevent and treat coronavirus disease 2019 (COVID‑19), but all clinical trials conducted during 2020 found it is ineffective and may cause dangerous side effects."

https://en.wikipedia.org/wiki/Hydroxychloroquine
Yes, this is strong. Worth noting the limitations though:

> Randomization generated groups with comparable percentage of unfavorable risk factors as there was no significant difference in subjects with at least one risk factor, except for high blood pressure and diabetes mellitus, known risk factors for unfavorable disease progression [2], which were more frequent in patients not treated with calcifediol.

These are HUGE risk factors. Also:

> This pilot study has several limitations as it is not double-blind placebo controlled. On the other hand, in the first studies evaluating risk factors for severe disease and/or death from COVID-19, the possible role of obesity was not considered. Therefore, given the isolation characteristics of the patients, we did not collect the BMI, which would have allowed us to add obesity as a risk factor for severe evolution of COVID-19 [37] It is striking to consider that obesity shares with aging and black or asian ethnicity a surprising overlap as risk factors for severe COVID-19 and vitamin D deficiency.

Yeah, BMI would've been nice too.

Still, check out table 2. Even with these limitations, seems powerful.
No, heavy trucks wear out the road significantly more than cars and result in asphalt having to be replaced more frequently.

This is another case where the gas tax isn't really adequate for funding road issues due to the disproportional increase in costs to the increase in fuel usage by trucks. All of the light vehicle drivers subsidize the heavy trucks in all mileage/fuel based tax schemes.
Asphalt driveways start out as very dark black, and then slowly fade to grey. They also start out as very smooth, but as they fade to grey they become more textured.

I wonder if there's a relation?
dang pointed out that Graeber has posted some pretty interesting comments on this site[0], which unfortunately I cannot find right now.

I had heard of, but not read, Bullshit Jobs so his HN comments was my first exposure to him. Honestly, I just remember being impressed by his willingness to engage. I'm sure it was painful and exhausting for him, especially his repeated skirmishes with DeLong, but so many authors shy away from challenges to their work so it was refreshing to see someone come into the proletarian trenches that are HN comments and do battle.

I once set up a large bank (you've probably heard of the bank, you've almost certainly not used this specific project though) with server-side Adobe Flex. We were using Flex to display charts on the client, and needed a way to render the same charts for use in reports.

This would be really useful for similar modern projects.
I'm not sure, but I think modern trains usually use electrical braking instead of friction.
> Once you understand that, you can comfortably adapt to any new library/framework/whatchamacallit relatively quickly.

I disagree. If you know typescript, it's still quite a leap to be able to code with angular, and debug weird stuff where you stare at a blank page, and the back trace in the dev tools include not even a single line of code you wrote.

Also, the language isn't really enough. You need to be familiar with the tooling (npm/yarn, babel, whatever) to use most libraries; so unless you do everything from scratch, you have to deal at least with the churn of the toolchain.
Yes, but many ISO documents are not publicly available (they're paywalled instead, even though ISO doesn't pay the authors). The Ada rationale is publicly available, so anyone can see exactly why various decisions are made. That's useful for someone using Ada (obviously), but it's also useful for people designing any other programming language... you can often learn about a craft by learning about why people made various decisions.

Show HN: LibreSelery – Solution for the Open Source Donation Pool Problem
I prefer Forklift. It's more mature, and the purchase license for Commander One has a two-machine limit I don't particularly care for, and which they're not very loud about before you buy. Since I have three boxes, between home and work, that was a nasty surprise.

The MAS version of Commander One is better in that regard, of course, but it's sandboxed.

Edit: looks like they're to a -one device- limit for Pro Pack for Commander One. I can't recommend it. That's absurd in the current software culture of pay per head, not per seat. That shift is the one. good. thing. App Store gardens brought us, and I won't support a per seat model anymore. Setapp's seat lock is a compromise I tolerate only because there's no better alternative yet.
Hi HN,

Author here. QuestDB is a fast SQL open source database for time series. About a month ago we launched on HackerNews [1].

Today, I am excited to announce QuestDB 5.0.3 [2]. This new release includes our changes in memory mapping strategy, giving us better performance, as well as some major changes to the Postgres wire protocol support.

In this blog post, we explain our journey to improve QuestDB's performance, especially regarding memory management. Relying as much as possible on the kernel and avoiding extra layers turned out to be very successful.

Thanks

Vlad

Assuming they're paid for 40 hours a week. The parent was pointing out that flight attendants spend a lot of time hanging around airports that they're not usually compensated for.

I'm not arguing it's a bad job. Historically, it was seen as a somewhat exotic see-the-world job for young people. (And at least the Asian carriers sort of enforced that.)
They already deorbit Starlink sats regularly. The "prototype" birds from the first launch are being decommissioned. SpaceX could hit a button (well, run a script, probably) and Starlink would disappear within 2-4 weeks.

Earth orbit is kinda first-come, first-served, though there is some coordination for GEO and large constellations via FCC and the ITU. It's really not particularly crowded. Starlink in particular basically occupies only one orbital shell at the moment, and not a particularly popular one, though it'll eventually have three or so.

Looks promising, but I would want to see a true double blinded RCT on a few thousand people before we say that Vitamin D is an effective treatment.

Also, there's going to be a confounding question based on this study: is it just Vitamin D, or is it Vitamin D in combination with HCQ / Azithromyacin?

That said, it probably wouldn't hurt you to supplement with Vitamin D this winter, even if it doesn't treat Covid.
Looking at this - it seems very similar to Verta.AI
Both are doing data lineage/workflow management ~ git for data science workflows. Verta recently raised their series A and launched their platform too.
This experiment compares vitamin D to no vitamin D, and doesn't say anything about those drugs statistically.

Could the article have been by Robert Sapolsky? He discusses something like that in one of his later books, the one with a chimp on the cover where he talks about how male chimps leave their childhood tribes and head out to seek mates... and the adjustment of moving from a close-knit social group to a new alien group is covered.

He's an endocrinologist/anthropologist by profession I think, but his books are sort of more about anthropology and psychology.
I used to work two desks over from Dan at the Obama campaign in Chicago in 2007, when he was developing and testing an early proof of concept of what would become Optimizely. He was able to increase fundraising performance significantly by doing (what would now be considered simple) A/B tests. He's sharp and tenacious, identified a market ahead of its time and invented a new product category.

Whether or not this is a "good" exit, it's a great accomplishment for Dan and the team and can't wait to see what they do next!
This is true for most "news" organizations at the moment. CNN, MSNBC, Fox, etc., are entertainment. Much of what they produce would fall under the Op. Ed. section of a newspaper. And the speed of the news cycle does not allow for rigorous fact checking and adequate opposing viewpoints to be included. "We have reached out for comment" is a common claim when there is a failure to include opposing viewpoints.

The problem is compounded by social feeds (Facebook, Twitter, etc.) that are engineered to only show you information you already agree with being the primary method of consumption. And then the comments within the article or accompanied in the social platform further drive home the biases.

Traditional print journalism, while never perfect or completely accurate, at least presented a consistent and uniform experience for all readers. The news cycle was extended to provide more time for fact checking and information/quote gathering. And the structure of the paper was clear: news, opinion, entertainment, etc. These never mixed. And corrections were clear and available in the same place in future issues.

That doesn't mean biases never existed, but the expectations were much clearer and there was less of an ability to focus on a segment of a market and ignore the views of others.

6 feet helps. Wearing masks helps. These things do not drop your chances to zero. 6 feet is not a universally applicable number. If you are standing directly down-wind of someone at a park, 6 feet isn’t going to help you. Droplets don’t magically disintegrate at 6 feet. Similarly, if you are up-wind, even 4 feet would be very effective.

All of the guidelines are about statistical safety, not about the physics of your particular situation. As always, use your noggin. Stay safe.
OK, but you also shouldn't disregard ethics. Even if you have the most egregiously simplified view of capitalism, disregarding ethics continuously can catch up with you.

If you try to skimp on paying your employees, they will find ways to return the favor. Trust me, I worked in retail.
I think Google is less of a threat than many believe because Google products have to address a Google-sized market which leaves tremendous room for competitors. If you're going to go straight up against Google then, sure, you're going to get clobbered.

> Is there anyone who would argue that React Hooks are "intuitive", or at least become that way after you've used them for long enough?

Yes. I've been using React for a while, started with class and functional components very close in time, and almost immediately found functional components with hooks far more intuitive than class components and lifecycle methods.

Of course, I also started programming before the mid-1990s OOP hegemony, and while I did use OOP early on my programming career, I also used lots of other paradigms early on, too. I think for people whose programming knowledge is entirely OOP, Class components and their lifecycle methods are probably more intuitive. Though given that React imposes unusual restrictions on state management in class components, that mean using usual OOP class design doesn't work for class components, I find even that a bit odd. React’s rules attached to hooks seem a lot less uncanny valley to me than React’s rules applied to classes.

IME, hooks get awkward mostly when a component is managing too much unrelated local state—which in a class component (or, really, even a functional one, though one associates this more with OOP) would mean you are flagrantly flouting the SRP. I actually find the friction that hooks provide in that case—which does seem to bite sooner than with class components—a welcome nudge to reassess responsibilities and refactor before the component becomes unmanageable. (And usually that involves moving more state management out of components and into, for the apps I work on, redux.)

At least for freight trains and normal passenger trains (especially diesel), that's probably true.

High speed trains usually use induction brakes (regenerative braking) and as such, they don't produce nearly as much brake dust.
Also, freight trains generally don't need to brake very often, since the tracks are free for kilometers to come most of the time.

In general, trains are of course far from emission-free, but as they can transport way more passengers/freight the emissions per person / tonne of freight are still lower than cars or trucks.
Python many times had the problem of being defined as CPython. Modules that target multiple Python implementations often have to work around differences between them, without a standard they have to look into implementation details of their targets. Not having a standard is definitely a pain.

But for most intents and purposes Python is defined by its documentation, and it's fine.

Having said that UB in C and C++ means behavior that the standard doesn't define. If you remove the standard then UB either loses meaning or it makes all programs undefined. It definitely doesn't make all programs defined.

That is mostly correct based on the studies I have been following.

There is a whole lot more going on, all the way from interactions with ACE to VWF to clotting, that administering zinc ionophores late in the game may be a bit too late.
