Sure. Trains in very dense areas with homogenous travel patterns (e.g, commuting to work) and roads everywhere else. Essentially what we have today in many places.

Of course, commuting to sit in front of a computer all day is pretty absurd. Maybe unnecessary commuting is the real problem.
It occurs to me that one reason we have such a winner-take-all tech economy might be that VCs don't want anything else to exist.
That is literally what we have now.

It seems this is a mainland China study. “Eye exercises” here has a particular form, which is called 眼保健操. IIRC it was developed during the cultural revolution based on traditional Chinese medicine. In short, the conclusion is that this particular exercise doesn’t work, not that exercises for eyes in general don’t work.
Customers have no direct relation with Snowflake, so they should go after Ticketmaster. Ticketmaster can then decide to reclaim their losses from Snowflake or some kind insurance they may have, but that's not their customers' problem.
If you’ve ever discussed politics with people online you’d know why.
In the same way that you can take a simple idea like iterative and responsive planning and turn it into a management monstrosity like agile, so too can simple goal setting and alignment be turned into the management and performance review monstrosity that is OKR.
This is the sort of pointless hackery I love seeing. Keep it up!
It is not about directly tapping into the rainwater collection, but managing the rainwater run off into ocean.

'Watersheds' are meant for that, and development of that is a serious endevor.

When rain falls on dry ground, some of the water soaks in, or infiltrates the soil. Some water that infiltrates will remain in the shallow soil layer, where it will gradually move downhill, through the soil, and eventually enters the stream by seepage into the stream bank. Some of the water may infiltrate much deeper, recharging groundwater aquifers.

Not sure why you put Tim Cook and Zuckerberg in the same sentence there, one is a founder the other is a climber. Building a big functional company like Zuckerberg did isn't something just anyone can do, Tim Cook just took over a big functional company and made it continue do what it did before. I think it will be a while until AI can build companies from scratch, but I think just running a company and keeping it do what it currently does wont take nearly as much.
> The author is attributing intentionality to something that has no free will or even sentience. Capitalism and the market economy are simply people who owns things and who make decisions to buy things.

In the same sense the human brain has no intentionality or sentience - it's simply neurons wired together, trading chemicals and jolting each other for shits and giggles.

Sometimes a high-level process works in a way not obvious from looking at individual parts, or even dependent on them. See also: corporations are effectively alien minds, AIs executing on top of a runtime made of humans.

> People need/want a certain item, value it to a certain extent, and are willing to part with some number of dollars to receive that value. If a large number of people do not highly value an item (...)

That breaks down in practice, because people have finite time and energy to evaluate and make choices, while sellers have a lot of leeway in plain lying to their customers. As a result, people mostly chose out of what's available, and quietly endure it being shit.
Keeping stuff in pockets is overrated. There are ridiculously small portable laptops though.

> platforms will have already implemented real-identity features

FB already has this, in theory, but that doesn't stop people scamming with it. Those policies didn't even stop people organising a genocide: https://en.wikipedia.org/wiki/Facebook_content_management_co...

> Remember that the platforms themselves don’t benefit from AI content dominating everything and are pretty incentivized to ensure that content is from real people.

These platforms themselves are AI. Even when the posts are made by humans — and posts don't need to be "real time" nor do they need to be video — the feed is algorithmic to maximise your attention, and the choices of which advert to stick in front of your eyes are chosen algorithmically to maximise revenue… and even before the use of LLMs for copy and diffusion models for images, the ads themselves are AB tested by the businesses to see which have the greatest effect.
I think this forgets the most important thing: how to accurately measure the okr.

Okrs are primed to be gamed by people seeking to maximize their contributions even if it isn’t relevant to a real world scenario.

No - but OO wasn't as successful at delivering code reuse as it was promised to be, especially polymorphic OO.

SE won't be real Engineering until we start being able to do things like measuring the robustness of a system, or projecting it's maintenance costs. I think we are as far away from this as we've ever been.
Optimizing 128-bit Division (2020)
(I work at Notion, one of the larger Notion clones)

We experimented with using partitioned tables and doing the fancy postgres_fdw thing when we sharded our tenant-clustered tables in 2020. Even with all the Postgres instances in the same region we found the approach unwieldy. Routing queries in the application gives you a lot more control versus needing to teach Postgres the exact logic to route a query, plus do a (dangerous? one-way? global?) schema migration whenever you want to change the routing logic.

We touched on this briefly in our sharding blog post here: https://www.notion.so/blog/sharding-postgres-at-notion

Another reason to avoid complex routing in Postgres is risk. If something goes wrong at 3am in a load-bearing cross-Postgres-instance query, how easily will it be to mitigate that if the routing is happening in Postgres (with whatever advanced clustering system Citus, pgzx, postgres_fdw) versus if the routing is happening in the application? For example if there’s a network partition between the “global” postgres instance and the us-east-2 cluster? Maybe you’re Postgres wizards and know how to handle this with a quick schema change or something in the psql CLI but I’d bet more on my team’s ability to write fault tolerance in the application versus in Postgres internal logic.
Well yeah, there's no potential to cheat the environment by pretending to be fit (as somebody already commented), except mimicry is a way to do that (as also already mentioned). But you can be successfully unconcerned about quality, hoping for returns on rare successes, like with the Chinese Santa snowglobes mentioned elsewhere in the comments.
Indeed!

I wonder what caused all this madness. Doesn't it degrade productivity? And thereby hurt profitability? And thereby the attractiveness of such strategies?

It sometimes seem to me like profit motive has been replaced by a power motive, like money isn't real anymore, but the legitimacy of private ownership is.

Good times. Back then I used this trick and paired it with an non-laser-locked modded Geforce 6800 AGP card for some gaming. I was lucky that my GPU handled having the disabled cores re-enabled without any issues, and the subsequent performance gains were huge with the additional unlocked speed from the CPU. I stuck with that GPU and CPU combo until the 9800GTX+ dropped.
I asked ChatGPT and it came up with these cases of deception strategies in nature (I wasn't excluding mankind, it thinks man, and probably itself doesn't belong there):

Mimicry/false signaling/bluffing (look more dangerous, look inpalatable, distract attention, attract prey), camouflage (avoid being preyed), brood paratism (cokoos get parenting for free).

None of them involve deceiving partners into pretending higher level of fitness.

Thinking about this it becomes a little clearer why this is.

When you're buying a sofa the seller usually doesn't buy a sofa made by you. So there is an assymmetry. The sofa dealer not only monopolizes most information about the deal (factual quality, costs; competitors are shared information). Also, the dealer can influence what you think. Economies of scale at play both in advertising and production.

Secondly, only if those two sofas you exchanged were to be used to produce the next generation of sofas and only if those newly merged sofa designs would be the sole base of contemporary sofa design would this comparison hold.

Then it becomes clear that if both parties engage in deceiving each other the species as the hypthetical owner of all evolving sofa designs must lose.
Another solution, apart from custom hooks is the queryOptions helper function:

function postQuery(id: number) {
return queryOptions({
queryKey: ["posts", id],
queryFn: () => fetchPost(String(id))
})
}

function App() {
const [id, setId] = useState(1);
const { data, error, isPending } = useQuery(postQuery(id))
}

See https://tanstack.com/query/latest/docs/framework/react/types...

In addition to fixing this leak, it has several advantages:

- It DRYs the QueryKey

- In Typescript, it tags the QueryKey with the return type, giving you type safety in utility functions such as setQueryData

- Unlike custom hooks, it gives you more flexibility if you want to use useSuspenseQuery, useQueries or if you want to prefetch the query.
It's indirect, but in their policy programme (https://volteuropa.org/storage/pdf/eu-elections-2024/volt-eu..., page 45) they mention:

Transform the Declaration on European Digital Rights and Principles for the Digital Decade into a binding legal instrument, so that the Declaration is upheld at every step of policy making.

The Declaration that they mention is not from Volt, it's from the EU itself and can be found here: https://digital-strategy.ec.europa.eu/en/library/european-de...

Privacy and individual control over data

17. Everyone has the right to privacy and to the protection of their personal data. The latter right includes the control by individuals on how their personal data are used and with whom they are shared.

18. Everyone has the right to the confidentiality of their communications and the information on their electronic devices, and not to be subjected to unlawful online surveillance, unlawful pervasive tracking or interception measures.

Of course, given that this Declaration is signed by the same parties that are currently pushing the ChatControl measures being discussed doesn't fill me with much confidence.
I guess it depends on the company, because in our company it is very encouraged, if a person really works well, does not sit in social networks while working, by the way, we have a program for this purpose Kickidler https://www.kickidler.com/ and it is unreal convenient that there are separate profiles for the whole team, you can go to a particular employee and see his pluses, minuses, in general, a whole report, and for those who are good at it, you can write a very good bonus

Here's the thing I learned, tying it to revenue gets the company more revenue, tying it to BS gets middle managers promoted faster. Why? Because money may not materialize while BS doesn't require anything except itself to be a success. And since your own promotion and bonus are strongly based on how much middle managers like you...

100%, and to make matters worse - the consequences don’t even matter to them. They don’t care if people find out, because all they have to do is outlast that medium price/quality point business and they’ve won, and once they’ve won, it’s game over, that middle section isn’t coming back anytime soon.

Similar here. For a very long time, I thought that being good at something was knowing the system and rules, and applying them consciously every time. It's funny because I legit thought that that's what I was doing while playing video games or doing martial arts (the only things I was reasonably good at for quite awhile). It turns out the learning and doing processes are both deeply subconscious; very little goes on in the conscious mind during both.
I took what I got, which is less than you assume, and didn't demand more. You seem to think I'm arguing against mentorship entirely. I'm not.

I know the value. I didn't get much; I barely even knew my father. I'm going to get distasteful for a moment because of that. You've been warned.

To answer your snide fucking remark: I did in fact succeed without coaching. I wouldn't be so harsh if I hadn't just read you go after someone for a similar attack. Amazing.

Now, back to civility.

There has to be a limit. We don't make seniors to collect them. We have a job to do beyond sustaining the ranks.

Also: it's a subjective title. Who's to say I'm not a junior that snuck in?

Among the pool of seniors there's no consistency in capabilities. It's all arbitrary. Calm down and go back to work.

To close all of this, nobody is owed a promotion or even attention. Selection has to happen. Maybe that's not you this time. Sorry.

While I work from home, I have traveled to teach and attend classes. I get it. I try to use the advantages of both.

It's well established that the way to move up in the industry is by changing jobs. I don't like it but that's how it is. We can team up but I don't like our odds.
> This kind of transaction is exactly what modern capitalism is trying to stamp out.

Yet again modern capitalism is blamed for its users' lack of taste: people genuinely prefer new, crappier stuff to classier, old items. This is the same with Tik Tok algos, tailors being unpopular compared to fast fashion and even overpriced luxury brands, fast food vs cooking, etc.

Virtually every time a consumer is confronted with a lousier but easily available option and a vastly superior one but requiring some mental, or occasionally physical, effort, they choose the former.

Capitalism merely holds up a mirror to our preferences. As it turns out, we really don't like it.

My charitable view is, they can serve as an error correction function in a product led org. I.e., product and sales people don't care about the internals, just feature, feature feature. Over time this increases entropy. OKRs can be used to make time to address entropy.

"slop" being the key word. I remember when all 3D animation was "slop".

But even ignoring technological progress, lots of people have regularly criticised mass media for being "slop", and yet the masses keep eating it up — the other side of that coin is that even if we had an AI that was essentially a perfectly sublime artist, I'd expect it to go like this: https://www.smbc-comics.com/comic/ai-12
How is money spent on childcare different from disposable income? Differentiating them artificially would fail to account for people who want children, but don’t, because they don’t feel they have the income. Which is a lot of the middle class at this point.
Previous HN comments indicated this could just be demo snowflake accounts, which were all compromised from a single individuals account at snowflake. But the announcements don’t seem consistent with this. Do we think propective customers really shared 100s of millions of real customer records for demo accounts? Or more likely the sales person was granted access to production systems by the prospective clients, so their credential without MFA could be used to access many customers real data? I struggle to see how snowflake can blame the customer here; secure by default is something a customer should reasonably expect for their money.
Lid has more meanings though. It can also mean "inclination" or "hillside" (roughly) which makes more sense in the context. Grönlid would then be a green hillside or green slope or similar. Which sounds like a nice place to lay down and relax for a bit.

Only if you reward people based on completion. IF you just use them to communicate goals I don't see why they would be bad. When I worked we did OKR but nobody talked about them and it wasn't a big deal whether they succeeded or not, it was just a place to put goals, just like a bug tracker.

If you have a place where you write down goals you are basically doing OKRs, it is good to do in general.
