skysight-inc/HackerNews huggingface dataset:
The main public information is page 13 of the interface description [0]. I got some more specifics from Sensirion directly when I contacted them (the 50ppm minima thing in particular).

Not seeing fresh air for a week isn't enough to throw it off, it needs to not have seen fresh air for a week _and_ the baselines that it has seen have to be within 50ppm of each other.

Have you allowed it to calibrate even once? It needs 7d of uninterrupted power and daily fresh air for the initial calibration.

You can also do forced calibration against a known value using the process on page 14 of [0].

It can also give iffy results if the temperature/humidity values are totally out of whack, which could happen if it's put in an enclosure or something like that. You can set an offset using the instructions on page 15 of [0].

There's also altitude compensation but unless you're doing something really weird that shouldn't affect you so much.

Finally, there's sensor placement [1]. It shouldn't be placed in such a way that there's a lot of air flowing over it directly (e.g. exposed to the air). If it's in front of a fan or something it's going to do weird things.

I'd suggest placing it outside for a few minutes and see what the readings are. If they're far from 400ppm it definitely needs calibrating.

Forbes is part of the pro-regime change crowd, just like the nytimes, washington post, etc. If sanctions are so neglible, then why bother with it? Let venezuela crumble on its own. Or maybe the fact that it wasn't crumbling was the reason to sanction/destabilize/destroy it?

iirc some laptops do this. As soon as there is data transmitted from the camera, the light will turn on. Another solution would be the sliding camera cover some manufacturers have, but that doesn't really help with the built in microphone.
”wins in any aspects (expressiveness, flexibility, whatever)”

One ‘whatever’ where it doesn’t win is in robustness. Code will make assumptions about various kinds of animal and fail when meeting a sheep with 5 legs, or a pig that can fly.

You can solve that by testing for capabilities, but you would have to do that in many places, and make sure to cover all of them.

And yes, that comes at the cost of flexibility. Your class model won’t support flying pigs until you consciously add such support.

I think you might want to look at the PSD2 (payment services directive) standard, which tries to regulate this in the EU.

Most banks seem to offer environments for integrating with them (they are obliged to do so), in my understanding it's not a very enjoyable process though.

You will also need to register as a service provider to use this, I don't know how complicated that is. Some companies like Figo/Finleap provide higher-level APIs that you can use as a fintech/developer, maybe that might be a better strategy for you if your resources are limited.
I don't think Knuth put those together expecting people to read through them like a novel.

> Right - starving to death is always an option, nothing is forcing them. Free market at work!

The free market is not a welfare system, though it can contribute a great deal to welfare, by keeping consumer prices down. It can support a welfare system by being sufficiently productive to raise taxes to pay for stuff.

Meanwhile, those countries that do not employ a free market are poor across the board. Wealth is only achieved through corruption. That poverty is then blamed on "foreign intervention". Well, fair enough, but if your system can't handle that foreign intervention, it's still inferior.

> It's not 1980, that's a fallacy and has been for a long time. By and large, "farmers" are large corporations printing money.

Just because they're larger today doesn't mean they are printing money. It's a highly competitive business. Of course a large farm can be a bit more profitable due to economics of scale, but there's always pressure from the bottom, because the threshold to market entry isn't that high.

Just try to accept that nothing is wrong with business profits per se. Let's say farming businesses have a 12% profit margin[1]. That's the price you pay for them to take the risk of running the business, and to do so efficiently. The profit margin reflects the real price of that service, just like the price of labor. Absent of any monopolies, it's a fair price. You couldn't get it any cheaper by, say, making the government do it. To the contrary.

It might be partly because Postgres is largely developed by the providers of "3rd-party" solutions for features like this. You could see it as an open-core model of sorts.
Thanks for your interesting answer. It doesn't really address my question though, so I will rephrase it:

If I take a 720p video of a webcam and encode it to be delivered as progressive live streaming, the resulting stream is going to be less than one Mbps : because the image doesn't move much, I don't need many key-frame, one every 4 seconds is more than enough, and I've seen streams with no more than one every 30s (live streaming of harbours' CCTV cameras, don't ask me why). But of course it won't be realtime either, and you're gonna have a few seconds of latency. While this is OK for live streaming, it is certainly not for a video chat room.

What I'd like to know is why the latency requirement reduces that much the encoding efficiency. Do you have an idea ?

Addressing the quiet downvoters. It upsets me how dismissive our culture can be. What if there's something to it? There's a rich history of people thinking that there is. Do they really not deserve a second thought? I wish everyone were always a skeptic, but never off-hand dismissive.

To those entrusting our mainstream with authority on what's bullshit and what's not, remember that psychedelics research is still illegal most places. I'd argue that history is random, and thus the mainstream. Further, variety is a good thing: the more of it we can sustain, the healthier our society is.
Logical replication has been in PostgreSQL itself for a while now.

There are naturally caveats: sequences don't get replicated, so you need to configure each replica with a non-overlapping range for each sequence. And DDL statements are also not replicated, so you have to migrate database schemas by hand on each replica.
I mean, it's not really fair to judge its worth if you're not viewing it on the medium it's intended for.

On the other hand, it is a good reminder that a lot of media actually is viewed on other devices than the one it was supposedly targeted at. Indeed netflix itself is largely a company doing just this: taking movies and displaying them on laptops and phones.

So is the idea that this anime is solely for those that own a 4K screen and pay extra for the 4k stream from Netflix? Or does the remark that many people will not benefit from the new capability at all carry some weight? Indeed those without 4K devices and accounts might get suffer as the aspects they can view has been made at lower quality as a cost saving.
There's every month here and on reddit such lists with best programming books, I guess it's profitable to recommend them?
It isn't, and this is the vocal anti-anarchist contingent voicing their POV as fact when in reality he had stepped down from IHES after he realized his work was being funded by the French Military [1] in some Academic-Military collusion and couldn't continue any longer--not unlike DARPA has with MIT in modern times.

He had a greater regard and estimation in his colleagues and Academia as a whole that turned out to be false as none followed him in protest and he then dedicated his Life to Environmentalism. He even shunned his Field's medal and rejected all the awards that followed.

He, like many other Anarchists, felt that the State's continual and expansionist military activity needlessly contributes to the haphazard and headlong demise of the World's Ecology--which threatens all of Life on Earth--and wrote at great length about it. And sees the State as an imminent threat to Humanity as it accelerates our demise as a Species.

I learned about Grothendieck's amazing Life and his work upon his death in 2014 (a month or 2 after Hal Finney died) in a very defining period of my Life, not just as an anarchist myself but as a Human and this article's final paragraph summed up what I think he wanted to be remembered the most as it was a Life well lived.:

The man who had advanced mathematics in the most profound ways did not believe that math was the answer to everything. He taught us that life is more valuable than any equation.

>The figure of the family doctor that takes his time and actually shows you attention has vanished. The average experience of a hospital visit is that of being treated like a number.

This doesn't have to be so (indeed in many places it isn't yet). This is a consequence of a strained public health system which is simply running over capacity.

Maybe if we stopped pumping money into banks and wealthy people's pockets we could have some left for such purposes.
I've been using an LG OLED TV to grade HDR footage in Resolve (in ACES). They don't quite hit 1000 nits but not too far off, and the colour accuracy is excellent.

Will be interesting to see what the new microled displays will be like. With those in an iPad (hopefully end of the year) you could draw directly on a HDR display.

As an aside - I wish Procreate on iOS had full on animation capabilities. The current layer per frame animation is super basic. If it had a proper timeline, rigging, tweening, maybe even pose/face driven character animation from iOS camera.. it would be amazing.

Would also be great if iOS supported professional video codecs - I think iPads could be an all-in-one solution for many animators if the OS and software was better.

You just said you never saw Postgres at Yahoo. Yet Yahoo had possibly the world’s largest Postgres installation. I consider that legendary. I’ve certainly been aware of it for over a decade. It was also an early (?) columnar store which is now commonplace among OLAP databases. Seems like if it didn’t start a trend it was at least an early adopter. I’d say that’s legendary too. Even today the scale is impressive.

Now you say you did see some
Postgres but there was more MySQL. Fine, you were there, I’ll take your word for it. But I can’t reconcile your own statements on this. Yahoo very clearly used Postgres.

Extraordinary claims require extraordinary evidence.

None was provided, so we will have to dismiss it until some proof is provided.

Nobody is dismissing proof here. They're only dismissive of the extraordinary claims that an immeasurable energy somehow inherent to some things has any effect beyond essentially the placebo effect. After all, there hasn't been any evidence which showed differently.

If you have some studies showing actual results beyond placebo's baseline, we'd all be ecstatic for the new knowledge
>I dream of an economic system that serves human beings instead of the numerical abstractions behind which the rich and powerful hide their extreme selfishness.

This is what capitalism is in its essence - a complex decentralised pricing mechanism where every human's choices is taken into account on the free market. The problem is that it has been corrupted by cronyism which has indirectly destroyed the human element of it (through centralisation and the formation of unnatural state-sanctioned monopolies and rent-seekers) and instead, as you put it, abstracted people into numbers.

I don't think anyone actually wants to be treated as a number, and I strongly believe that personal and bespoke service is a quality that most people seek in the services they choose (especially medical and caregiving services). These preferences would normally provide strong competitive pressures. However, in the medical field at least, enormous barriers of entry (largely instituted and enforced by the state) has fortified incumbent corporations and removed the competitive pressure that startups and newcomers would provide. Just look at medical education/licensing and the enormous costs involved.

I enrolled my wife and I in a local Permaculture Design Course as part of a Christmas present (she got us into bees last year). Unlike most 2-week intensives, ours is taught every other weekend for about 3 months.

I think many people here on HN would be interested in permaculture. There’s a lot of the same design and systems thinking that appeal to computer programmers. As noted by others, permaculture is also really into the hacker ethic.

It scales up and down really nicely, and can fit into your urban, small apartment lifestyle, or your suburban backyard, small acreage, or even big farms.

What it has me thinking about most, is what set of ethics and principles can/should I take to my practice as a software engineer. Permaculture is a design method based in a set of simple ethics, that lead to a set of basic principles, that help you select, adapt, and use various practices.

Is there a “earth share, people share, fair share” set of ethics that could become the basis for how you solve tech problems? Is anyone familiar with an existing author or community that seeks to address this in tech? Would love references.

PostgreSQL is also my go-to database for anything relational. My only issue with it though, is the need to run vacuum full (which locks tables for significant amount of time) to free up disk space to the operating system.

One day, I might get the burr grinder as a 'reward' for all the discipline I show in most aspects, or some other justification that I can coax myself with. :-))

As for coarseness, I'm living with a "workaround": 12 pulses (manual on-and-off; yeah, annoying) with the blade grinder to get the right coarseness for French Press, which is now a "weekend delight".
