This looks great! Recently I've been wanting to make a hand-tracking library for video editing. I'd make a hand gesture like an OK with my index and thumb to begin recording, and when I was done I'd make a thumbs up to keep the take or thumbs down to delete a bad take. That way, I could very easily record stuff while only keeping the good takes, to sort out later.

Hell, the library could even stitch the takes together, omitting the times when my hand started/finished doing the gestures.
You are on hacker news. Left is good. Right is bad.

Facts and reality will not change this formula.

You are absolutely right. Just read the comments, not even "on the internet" but right here on HN. Some even seem in favour of a... "more extreme" solution yet than internment, and have not a shred of self-reflection when they talk a mad game about others being bad people.
It’s good to see there are CentOS alternatives available. The rug pull that Redhat did last year was nothing short of surprising, at the previous company I worked for we had to scramble at the last second to find a replacement. I no longer work for that company, but I still get emails from Redhat. They have the audacity to ask me if our team still needs help migrating from CentOS to RHEL.
"Lying" implies intent to deceive. You can't know intent from internet comments, so that's a personal attack, and personal attacks break the site guidelines. When another comment is wrong, it's enough to respectfully supply correct information.

Yes, we warned you 9 months ago, which means we warned you. If you break the site guidelines after we've already warned you, you're a lot more likely to get banned—and you broke them repeatedly and egregiously. This is not a borderline call!

They should've stuck with Stellar, for any realistic money transferring between people (merchants, p2p, cross-border), Stellar is one of the best options as the fees are insanely low compared to any other large cryptocurrencies.
My strategy: get really clear on business needs/objectives/internal SLAs for infrastructure. In my experience a lot of time-consuming stuff revolves around uptime, data recovery (RTO, RPO), security, compliance, and scaling. Depending on your business and the stage you’re in, a lot of that may not matter, so don’t build anything you don’t need now.

I’m a solo-founder, with many years working in IT, and I focused on DevOps for part of it; I know what best practice looks like and it would be easy to fall down that rabbit hole doing an unnecessarily complex buildout. Currently I’m doing a small private beta, I’m avoiding 99% of standard practice. I’ve got a single EC2 node running Redis as the only datastore and NodeJS + Nginx + certbot, a cron to do backups to S3. No CI (there are no other devs to integrate code with) I run all tests locally and push/rollback with rsync. All code, assets, and server config (except creds) are in a monorepo.

If the server goes offline, I will have a little downtime, that’s fine. If I run out of memory for Redis (not likely to happen soon), I’ll change to a different datastore or scale up the node. If I lose data, I can restore from S3, and additionally the architecture is such that clients will re-push their latest changes.

Do the bare minimum to support the business, stick with what you know, outsource what you can, and properly value your time.
My understanding is that this is like borrowing water from your house and returning it into your septic system with “gratuitous” waste in it. It’s dumping entropy, or “stealing” a low entropy state on the plantiff. Not sure if this is the technical answer the article wanted though.
I live in the USA. My friend Kristin is from Germany. She got her driver's license in Germany when she was 28. She trained awhile for it and then took 3 tests: city driving, highway driving, and nighttime driving. From how she described it, the training and the testing was much more rigorous than anything that has existed in the USA.
thankfully higher refresh rates & even mini-LED are starting to emerge already (the first, the, MSI Creator 17 is ~1 year old now!).

i would love to see this tech adopted more actively. high-refresh looks amazing. so weird that we told ourselves we can't see beyond 60fps, that we convinced ourselves, for so long, because computing looks so much better at higher refresh. mini-LED's local dimming zones do decent at getting good, rich contrast pictures. their capability to run at high brightnesses is great for stunning visuals & road-warriors alike.
you are focusing on pollution in terms of sustainability, but perhaps fission is unsustainable because it relies on "fuels" which can run out? there is only a finite supply of uranium.
"But while labels like “terrorist” and “criminal” are conceptually broad, they look more like narrow racial and religious proxies once you see how they are applied to people and groups in the list, experts said, raising the likelihood that Facebook is placing discriminatory limitations on speech."
VGG also has regularization (L2, dropout, maxpool) if I remember correctly so it's sort of odd to use that as an example of overfitting when it explicitly tunes against that. I'm guessing the epochs and learning rate were also tuned to lower overfitting. The same is true to every other popular network out there.
It is embedded in various places on the web - e.g. duckduckgo uses it. You don't get a choice if the website owner forces it on you
>Yeah you're getting downvoted because your championing Limbaugh and Fox News, known liars. Probably in your reality they're champions of truth, but seriously, your reality has some blind spots. Big ones.

Uhh, I am saying the opposite. I am just pointing out the misinformation spread which has nothing to do with CDC mask advice.
The other two answers are probably better, but in case it's useful take a look at https://en.wikipedia.org/wiki/Nuclear_weapon_design#Two-stag...

Between the primary fission bomb and the secondary fusion bomb there is a huge shield, so the shockwave of the first one hit's the second one at the same time everywhere, instead of hitting the top.

My guess is that to put a ternary fusion bomb you will need another even bigger shield, but IANANBS.
true this. In fact - im wondering why molten salt reactors which the US innovated almost 60 years back where not pursued. Thorium is plentiful and cheap - and Terrapower seems to have already productized cheap miniaturized MSRs.
Yes, but bulk of the demand is heat and industry, so you're quickly back to having to build a lot of "storage" in the form of buildings with high thermal inertia and spare capacity for production, so that you can keep the high energy plants idle at inconvenient times. Hard to say if that is more efficient than building actual energy storage.

Every little helps I guess, but getting people not to shower on cloudy days is not gonna move the needle materially.
This is a complicated topic. One thing I can recall is that there's more pedestrian collisions as there's been more safety technologies and larger cars and average vehicle miles travelled (can't find the study, this might be a lead: https://safetrec.berkeley.edu/news/new-release-2020-safetrec... )
I don't think it is accurate to say it "dissipates into the rest of the water system". Typically the hydrocarbon formations being fracked are thousands of feet below the water table, separated by thousands of feet of impermeable shale. It's the same, or more so, for disposal zones where the frack fluid that flows back is injected. For the fluid to mix with a potable aquifer, it would have to leak within a wellbore. That's possible, for sure, but it's pretty rare, can be detected through proper monitoring, and can be more or less eliminated as a risk when the well is ultimately abandoned by pumping cement down the well. You don't really need a computer model to tell you what's going to happen: the formations have been separate for millions of years, and they're probably going to continue to be separate for millions more.

I hadn't heard about them using the water for crops, that is a little more alarming to me. I suspect it's not being done quite as cavalierly as you're suggesting - they are clearly treating and testing it, as discussed in the article.

In my (maybe biased) opinion, all of this should be weighed against the alternatives. Gas is much cleaner than coal, after all. In Europe, they made the decision to ban fracking, and also eliminate nuclear energy (in some countries at least). Some of the gap can be filled increasingly with renewables, but as recent history has shown, not all of it. Most of the gap is filled with Russian gas, which has its own issues. And overall it makes the energy supply less robust, which allowed their current energy crisis to happen, when the wind doesn't blow enough and the Russian supply has hiccups.

I don't think it's fair to paint this as oil and gas companies reaping all the benefits while everyone else pays the price: everyone benefits from lower energy prices, directly or indirectly. In my opinion, consumers bear some of the responsibility for environmental issues, as well as the producers.
48v made sense years ago, the only reason we haven't done it is inertia. You're spot-on; the PSU is not making voltages that're directly used by components anymore, with the possible exception of 5v for USB and stuff. Everything else has a local DC-DC converter and the "12-ish" is used as an intermediate distribution standard.

Pursuant to that, the ATX12VO standard is a huge step in the right direction. It ditches the 5v and 3v3 rails from the PSU and uses 12 only. This requires only modest changes to peripherals, most of which were getting most of their power from the 12v rail already.

I think it's an excellent stepping stone on the way to an ATX48VO or something. That will require some more changes because a lot of popular power semiconductors are only rated to 30v or 35v or something, so there will be some push for a 24v compromise, but I think the efficiency gains with a higher voltage will ultimately win out.
> As for battery capacity, you seem to underestimate how much electrical energy even small cities use.

I'm not sure where you get that impression.

We are manufacturing around 500 GWh of new batteries yearly right now [1].

To put that in perspective, that's enough capacity for 1 hour of US annual energy consumption per year. 1 hour is a lot of time to bring up new power generation plants in the event of an outage.

That production rate has been accelerating with the new demand for EVs. That is likely to double or triple within the next few years.

The current largest battery plant weighs in at 1.6GWh, which is more than enough to power a city of 100k for several hours (it isn't currently used for that, it is stabilizing regional power).

Like all things, battery power will first be able to handle seconds, then minutes, then hours, and finally days worth of power requirements. For grid stabilization, that's more than enough capacity requirements.

And, as I said earlier, batteries are good for any grid, regardless of energy source. It allows a nuclear operator to run the plant harder and it allows plants to ditch fast ramping plants for more economical slow ramp plants.

In addition to being a large project to set up geothermal, they don't generally produce a lot of power. The largest deployment in the world is in California (The Geysers) and spans ~20 separate units, and each unit on average produces around 100 MW. A gas plant produces around 500 MW, and a nuclear plant about 1 GW.
DuckDuckGo's maps are powered by Apple Maps, so technically they do.
This might be a bit of a disingenuous take on it.

As far as I can tell they first created the membership and then when they happened to get some (limited) PS5 stock made it a membership exclusive. I don't think it's super weird that you would give your members priority.
Though, when 1 MJ is generated in a fraction of a second, that does mean its instantaneous output was in the MW+ range
> I have only seen null vs undefined lead to 2 things in my experience: mistakes and bikeshedding.

I disagree, though I think the implementation leaves something to be desired. Primarily, I think there is fundamentally a difference between the value of obj.bar in the following examples that is useful to differentiate between:

{ foo: 'hello' }

{ foo: 'hello', bar: null }

For example, GraphQL makes specific use of this when dealing with input types for mutations: null essentially means "delete this field" while unset means "don't change it".

There is a very good discussion on this topic here, https://github.com/graphql/graphql-js/issues/133 , which goes into the rationale behind it, how it's supported in languages that do NOT differentiate between null and undefined, and how some folks changed their minds on the issue.
The 1000 miles road starts with a first step, and it's not like we can't pursue several approaches at once. People like grandparent poster suggest us drop everything and concentrate on the idea he likes best. That is a very bad and harmful idea.
Because once they lose their credibility, everything they say will be viewed with distrust.

> If the claim that masks "don't work" caused folks to distrust public health authorities

I would say it is more the contradictory messaging that caused the distrust, than the initial claim that masks do not work.
A Symbolic Guide on Logic
Given that one of Fauci's emails shows the same opinion on mask inefficacy, I believe the lie came in the 180 about face claiming they do work (and there wasn't any cost to imposing them).
Thanks. We are glad to be able to fill in the gap for the community.
This approach doesn't use magnets.
That's not a plus for the consumer and won't do much to enhance customer adoption and preference for the payment method.
He, actually I prefer the outer suburbs for bicycling because downtown is insane. In the suburbs I can tone the paranoia that everyone is out there to kill me at least down a little :)
I agree to an extent, but at the end of the day it's unrealistic. The government is an entity made up of people with their own biases, problems, and their job on the line if they fuck up. I think there is a meme of honorable government employee who will resign before letting down the American people, but the reality is most people (and government employee's) would be more concerned about covering their ass.

This is a long way of me saying that people are liars, the government is made of people, so the government will always lie. Same for partisan pissing matches. The important thing to me is how they react when new information comes to light, or they are caught out on their lies. Or when the lies are big enough (I.E. lead to great suffering), repercussions are put on the table.
I'm not sure. I read a lot of gun violence reporting like "person a was struck by a bullet and later died due to complications" vs "gunman shot and killed person a". It's kinda the same thing.

I would make no assumptions about if car accidents are accidental (which for some reason seems to be the default) or not - and that's more or less the point of the article.

I've been seeing two sides of this:

- Our own payments: Some remote contractors ask to be paid in crypto: haven't figured out clean way how wrt rest of our back-office SaaS stack, so not yet. To a much more negligible extent, our online customers want to pay that way: we do get a lot of proton etc. email users, so I can imagine more of this in the future, esp. as we add more privacy features. I bet other startups are seeing the same!

- Our power users: Crypto product & investigation teams often want to embed/use our GPU graph viz tech, and our inquiries have grown up from early VC/ICO-dependent startups to ones with $B+ assets under management. At this rate, seems like only a matter of 1-2 years for banks and big consulting co's for the same thing. So a big yet modern payment processor like Stripe seems quite sensible right now! (And I think Square was trying on and off for awhile as well.)
We still haven't reached herd immunity in the UK, and we have 49 of 67 million people vaccinated (plus some of the rest previously infected). The idea we'd have had fewer COVID casualties by allowing it to spread more easily before the winter is not one supported by evidence.
Do you mean a heat engine?

Because the "opposite" of air conditioning is just a heat engine (taking "hot" and "cold" source, and using the difference to generate locomotion). In fact, all engines are glorified heat engines: be it a steam turbine, ICE, geothermal, or whatever

When air gets hot, it expands. When air gets cold, it contracts. So heat up air through some mechanism (hot side) to push a piston up. To pull the piston down, either use momentum or the cold-source (cold air contracts, pulling the stuff down).

The sterling engine is the best general purpose demonstration of this, and you can buy such engines for $20 to $100 or so.

ICE engines use gasoline as the hot source. Steam engines use steam (water at 100C) to transfer the heat from the hot source to the needed locations (heat can be from nuclear, coal, or other sources)

----------

Air conditioning is just this process in reverse. Expand the air forcibly by applying force to the piston. This cools down the air. "Gather" the coldness through some mechanism, which heats up your air inside the A/C unit while cooling whatever is on your "cold plate".

Push the hot air and compress it down. This heats up the air even further: "transfer" the hotness through some mechanism (aka: heat something else up, like the air outside the house). This cools down the air inside your A/C unit.

Now find a fluid that's more efficient at this process than oxygen. Then realize that fluid is terrible for the Ozone layer and write a regulation for a newer, crappier fluid that's less damaging to the Earth, and you have modern A/C units.

> It seems like you’re removing energy from the air.

You're just transferring the hotness somewhere else. Go feel the air that your refrigerator outputs: its far hotter than the air inside. If you measure the energy, its the energy that was "stolen" from inside the refrigerator + the energy "spent" on the heat pump (that compression / decompression cycle takes work, and work generates heat)

We can transfer heat around, but it costs energy. Alternatively, a difference in heat can be used to gather energy, but it will "Average" the temperatures and eventually the hot-source and cold-source will be the same temperature.

We can use fuels to make the hot-source stay really, really hot for long periods of time (as long as we have a source of fuel), and that's basically the design of steam engines / heat engines.
What are you trying to accomplish?

> You are assuming "they" trust the Republican leadership. this Gallup poll says only 12% of Americans trust congress.

Congress ≠ the Republican leadership ≠ at least one member of the Republican leadership, or GOP members aligned therewith, enough to overcome dis- or non-trust of the rest.

“Congress” as an institution usually polls really badly when compared to individual politicians in their own districts, because Congress consists of 535 members, 532 of which the person answering the poll had no say in electing and represent people with different interests living elsewhere, and (usually) approximately half of which represent the least preferred of the two major parties, who usually have the power to at least block legislation (thanks to either split between the partisan majority of the House and Senate or, failing that, the Senate filibuster.)

Trust of either party leadership, and particularly voter’s own members of Congress, tends to be much higher than that of Congress as a whole.

Not GP, but for me performance is absolutely abysmal compared to just using podman in opensuse microos virtual machine (what I'm using now instead of docker).
I think the issue is this: there is a bias when certain news sources only mention facts about what drivers did right (like not being impaired) and about what pedestrians or cyclists did wrong (like not wearing a helmet).

We cannot easily detect this pattern of bias from just a sample of one article from the given source, however, even from one article, there can be a hint of this bias. For instance, a statement about the impairment level of the driver is not made, but the status about the bicycle helmet is made.

To avoid, or at least reduce biases, the reporter has to have a standard template of all relevant fact types, fill it in with everything that is known and then report on everything. If the cyclist was wearing a helmet, report that; if not also report that.

(The available facts may be biased, like what the police and other on-scene responders take in and communicate.)
The existence of natural gas keeps electricity prices low, which disincentives research into other power generation methods.

In a capitalist world, "lets do this until that is ready" plans usually just end up delaying 'that'.

A massive tax on carbon would mean we can all pay for 'this', until 'that' has been developed and we can enjoy low prices again.
> Obviously and that's my point. You are not going to avoid Google if you use the web. The best you can do is limit exposure.

That couldn't have been your point. It's very easy to avoid having a gmail account.

> This is ignorant and unhelpful.

People here don't know you personally, or your needs. Most people don't need gmail for work. If your job requires you to use google products, it's going to be difficult for you to avoid google. But, again, your situation is not representative of the vast majority of people.
Nerdctl claims to be able to run `docker-compose.yml` files as a drop-in replacement. How true that is (and how volume mounts work, if at all) I don't know.
Does rust have Mut annotations on functions?

I mean, when you look at a problem that monads solve with types is that every function has an “annotation “ of what it uses (IO or mutable state). Similar how async in JS allows await, a state annotation would allow put get or IO annotation any of the IO capabilities.

Of course monads are much more but Mut does not look like it pollutes everything with Mut, including function definitions and results
It's still less than half what's produced by coal or oil.

There are a limited number of locations where hydro is viable and most of them have been tapped (last I read about it at least),

I'm 100% with you on nuclear.

Regardless of cost, we need base load capabilities when the wind isn't blowing and the sun is down. Grid storage hasn't been well proven yet. People are actively fighting nuclear and the costs as well as timeliness are crazy. If there's one thing in this country worth wasting money on, it's nuclear.

If we can't get base load generation from nuclear due to all of the financial risks, NG is about all that's left to carry the load as an improvement over coal and oil.

I'd much rather have zero emission nuclear, but NG is the stop gap that we are left with until we start committing to nuclear (or we have a better round-the-clock option).
