CVT transmissions are not only available on hybrids although the Prius CVT is a thing of beauty utilizing the electric motors with planetary gears for continuous ratio.

None of the other things you mention have more than negligible effect on the highway at cruise speeds where the combustion engine will be providing all the power to run all systems either directly or indirectly at typically ideal rpm most of the time. Also electrical cooling pumps and power steering etc again are not tied to hybrids and many non hybrids are going that route. A/C again does not need a hybrid but would exceed the capability of a standard alternator and direct mechanical compressor drive with a clutch is not that inefficient, again that would mostly be for stop and go urban driving at steady highway speed it probably more efficient to run mechanically off the engine.

A small diesel car and Atkinson hybrid will have similar highway mileage mainly due to the combustion efficiency of the cycles not the hybrid systems. However the hybrid systems allow a Atkinson gasoline engine to have acceptable performance in the city while the diesel doesn't need it. An Otto gas car will be behind but the cost saving can buy a lot of gasoline.

Yes, I can see the double standards, too. There's no need to apologise though, I am not trying to make you feel guilty.

Industrial meat production is shameful, cruel, harmful to health and the environment and it should absolutely be replaced with something else- but that something else can't be another food industry stuffing us full of over-processed, well, shit (apologies - but this is really the best way to say what I mean).

>> It is also worth noting that as we speak the UK seems to be reconsidering it’s ban of hormones in meat as part of Brexit with pressure from the US.

Unfortunately, yes.
I looked at a few things including tridactyl when web extensions took out vimperator. After seeing the demos, I settled on giving https://krabby.netlify.app/ a try.

Copying all the links from a table in a go without doing some console fiddling is kinda nice when you need it.
I'm amazed that Swisslog system works reliably. All that precision track and rack. All those moving parts. There have been big automated storage and retrieval systems for decades, but they're often a maintenance headache.

The Kiva system just needs is a flat floor. The robots are mechanically simple and totally interchangeable. On-site maintenance is limited to replacing batteries and wheels; for anything else it goes back to a repair center.

> No developed country can accept all immigrants wanting to live there.

"developed": The US and Europe are rich.

"wanting": Other people want to be rich. That's why they come.

If US/Europe worshipped money less, they would be less rich. There would be less incentive for others to come, or for incumbents to keep them out. If you want to reduce flow, reduce pressure.

Here's the thing though: You, and your children, would have to work for a living.

> immigration does put pressure on a country's resources

Does it? Or are immigrants the resource being consumed? Seems to me they do the work. And once their children are Americanized, how many grandchildren will they have? Fewer. The US needs immigrants like a car needs gasoline. It eats them.

> if you let in everyone from South Asia, you will disenfranchise some South Americans, etc.

Only if there's a cap. Which is uncreative. Do the opposite. Aggressively add people to the ranks of the United States.

Imagine: Tomorrow, Trump comes on the TV and, in terrible Spanish, invites the people of Baha California (both states), Sonora, Chihuahua, Coahuila, Nuevo Leon, and Tamaulipas to hold referenda under Article IV, Section 3 of the US Constitution, about joining the United States. They'd be enticed by what's left of the "American dream", sun-belt voters would get a shot at cheaper and sunnier real estate, and factory workers could go to where the jobs are. The problem with NAFTA is that capital can flow but workers can't. So let the people move freely too! And if the Russians can run a foreign influence campaign to make Brexit happen, why can't the US do a Mexic-enter?

We can make the sum be much, much more than zero.
Still want 2 things for OBS:

The Fusion Triple Product, which is the key determinant of whether there is a self-sustaining reaction, increased faster than Moore's law up until about 2005. Then all the money went into ITER.

I'll be very interested to see what happens to OBS now that Nvidia is directly competing with them with Nvidia Broadcast: https://www.nvidia.com/en-us/geforce/news/nvidia-broadcast-a...

While it's community supported (though only at 2.5k/mo) I highly suspect that NB is going to outperform OBS in the coming years, just given the market Nvidia is trying to capture. Most youtubers / streamers don't need the full configuration capabilities of OBS, but rather just want something that works out of the box with the basic nice to haves (overlays, noise cancellation, basic text compositing / donation integrations).

Who’s Behind Monday’s 14-State 911 Outage?
At the risk of defending a faceless megacorporation, I'm curious what injuries per package look like at Amazon vs "Industry Average".

According to the article, productivity expectations per worker doubled with robotics, and Amazon has about double the injury rate per worker, so my super rough back of the envelope calculation says they should fare similarly on that metric.

If the industry alternative takes twice as many workers to do the same job, ultimately leading to approximately the same number of injured workers, has Amazon really created a safety crisis?

This is why people don't like marketers.
This is a good example of why I like open source. If someone decides to pull a move like that it can be forked and the project can live on.
Array.sort converts to UTF-16 code units, or some such weirdness, by default. If you are sorting anything other than strings, you will want to pass in a comparison function.

[1,3,2,4,5,7,8,9,10].sort((a,b) => a - b) gives you the behavior one would expect.

I suppose you already know that, though. Agreed there are lots of quirks.
If you hold right-of-centre views you definitely feel this already in all sorts of ways.

I've trained myself to always check the privacy setting of any post on Facebook before revealing my true views, knowing it sometimes shows my posts to family and left-wing friends, who have in the past demanded explanations.

You have this "watching over your shoulder online" feeling constantly if you try to maintain a bipartisan friends list.

This website captures an element of that very well.

I am, at least in my little personal corner, much more concerned at the moment with the actions of fellow citizens than with large corporations or whatever. For now.
Speaking of Amazon trying to downplay its wrongs, I recall there was a post here that counted Amazon PR team at 400-odd people. But I could not find it. Are they so effective or have I Mandela'd myself and this did not happen?
Mine actually worked well enough. Or at least they would have if they hadn't had such shitty power supplies. Every one of mine that burned out died because of an overheating power supply rather than because the actual bulb burnt out. This is a problem with a lot of LED bulbs too. Great light source that lasts 30,000 hours; shitty power supply that lasts 800 hours.
That's not really relevant to the point/counterpoint I was replying to, which was to do with personal risk. But I'm not sure it's true anyway; you can't transmit the virus to others if you're not infected! If everyone wore only N95s, transmission would certainly be lower than if everyone wore only surgical masks.

However, if it bothers you that much, you can wear a surgical mask over the N95. That's the best of both worlds, and strictly better than either option alone.

(All of this assumes valved N95s. Unvalved ones are more effective in both directions than surgical masks)
Here is a question I can't quite answer: why is the complexity of something like Xcode so much greater than NeXT, when many of the basic UI components are pretty much the same kinds of things they were 20 years ago (but, subjectively, better looking)? Is all this extra complexity warranted?
Is this based on any science or just a priori guessing?
Not to be that guy that always says "what do you want to do that for?", but it's possible you're looking for the wrong solution. If you buy ingredients and set aside time for specific kinds of recipes, you don't need to hunt for the recipes.

Get one cookbook of some cuisine you think you'll enjoy, and look for recipes that fit within a time frame you're comfortable with (keeping in mind that for many recipes, many steps can be done ahead of time or in parallel). For each recipe, make a list of ingredients and plan what to buy, when to buy it, when to prep it, when to cook it, and when to eat it (to anticipate a repeat cycle). If you follow this method you'll end up eating what you like, rather than what's convenient for a cabinet with ketchup, instant noodles, canned mushrooms, and dried basil. (Not knocking the poor man's pasta, just saying!)

Also, most recipe databases are awash with poor-quality imitations of traditional dishes, designed purely to cater to whatever your supermarket gives you, rather than good ingredients or healthy food. This doesn't mean you should buy $4 tomatoes, but even a different thickness of noodle can make a big difference. (Though Jersey tomatoes are worth the price; just don't refrigerate them!!)
If you have a computer hooked up, you don't need the TV to have internet.
I am not necessarily saying that leftists are a panacea of altruist thinking, having washed away their colonial upbringing in their dialogues with a theoretical minority. ;)

Rather, I understand leftist thought to be rooted in questioning hierarchy and power structures, which I believe leads to more readily seeking solidarity with those that are not as well off as they are.

> By coincidence, today I saw a debate where a strongly left-wing person dismissed some complaints of a marginalized person

This does sound like a funny happenstance. My original reply was about this same sort of funny coincidence in reverse; how I often see the left critiqued as being "intolerant" when I frequently see them lifting and amplifying the voices of those who are disenfranchised by the system that they materially benefit from.

> How much would a white left-wing person be willing to debate with e.g. a conservative immigrant?

First, debates are not typical discourse. In my experience, debates are meant to be a show of virtue. Whose virtues you're being weighed against will greatly determine your behavior or whether you even decide to participate at all. I think that Hacker News values sound, well written arguments, which is why I am here posting. :)

Therefore, I think that given the propensity toward identity politics (from both sides) and the difficulty in interrogating the root of the beliefs that immigrant without appearing to be questioning the validity of them, I (as a white leftist) would prefer not to debate them. So, yes, I would rather propose someone whose lived experience might be more similar to theirs - perhaps a left-leaning immigrant - specifically because I would be afraid of either appearing weak in the eyes of right-wing spectators by deferring to their lived experience, or seem like an asshole because I am questioning the validity of their experience. It would be a PR nightmare. :)

In a private, personal setting (i.e. not a debate) I think that talking to your hypothetical conservative immigrant would probably be a great opportunity for me to learn about their experience and explore the root of their beliefs. I hope I would get to share mine as well.
I'm going to stick to my existing method of shipping USB sticks to the TV I think.
Those tax negotiations regarded high pay white collar jobs. We are talking about warehouse work here.
It seems like what you're describing as positive is only a small part of what the article is complaining about. How did you get from e.g. 'If you have "bad friends" on social media you might pay more for your loan' to the return of politeness to society?

I agree that it would be nice to see people imposing their views on others less - "Live and let live" is a basic requirement of a Liberal society. But the dystopian future evoked by this microsite is sort of the opposite of that - an enforced uniformity, where instead of tolerating difference we attack it until people learn to hide it more effectively.
> There is already a great deal of equipment for manipulating hydrogen on an industrial scale

If by "a great deal" you mean "a fraction of one percent of what is required". No, the issue I'm raising is not well solved. Currently hydrogen is used shortly after it's produced, typically for chemical manufacturing or oil refining. It's not being stored for long periods of time, nor is it being transported in anything close to the amount of natural gas.

> The great majority of methane storage is underground as compressed gas, not cryogenic. Underground storage is cheap; the capacity in the US is a good fraction of the annual consumption of natural gas here. It is this long-proven technology I am referring to, which should have been clear from what I wrote earlier.

That's assuming these underground storage will work with a substance that has greater permeability. And storage is only half the problem, it's also a matter of the infrastructure used to transport gas to the end user. Simply pumping hydrogen through the same pipelines as natural gas isn't as easy as it sounds. Hydrogen has greater permeability and turns metals into hydrides at pressure. Hydrogen pipelines need to be much more corrosion resistant.

To put this in comparison, the US has 2 million miles of natural gas pipelines [1]. It only has 900 miles of hydrogen gas pipelines [2]. Most hydrogen is produced near areas of demand, and is not transported for long distances or stored for long periods of time. There's research into carbon-fiber pipelines that could better resist corrosion, but this is not a mature level of technology. It's more feasible to pipe methane, and then use steam reforming on-site.

> The density of hydrogen gas at STP is less than 0.1 kg/m^3. Divide to get 7.0e11 m^3.

Volume doesn't matter, I converted the volume of methane produced to mass.

> Globally, 6% of natural gas production is used to make hydrogen. I wasn't talking about hydrogen production by electrolysis; I was talking about total hydrogen production, to show that hydrogen is a material that global industry already has vast experience with.

Excellent point, total hydrogen production is 70 million tons with most of it produced through steam reforming (which produces carbon dioxide). Electrolysis only accounts for 4% of hydrogen production: https://en.wikipedia.org/wiki/Hydrogen_production#Methods_of....

The fact that 6% of natural gas production is used to make hydrogen doesn't mean that our hydrogen production equals 6% of our natural gas production. Most of the natural gas used in steam reforming is used to produce heat. And methane is 75% carbon by mass.

To recap, we have 3 orders of magnitude less hydrogen production and hydrogen transport infrastructure. Even less if you only count hydrogen produced through electrolysis. This is in no way "a great deal of equipment for manipulating hydrogen at scale".

I wish these people the best, and I really hope they get a working fusion plant soon. That said, I can't resist sharing Admiral Rickover on academic reactors vs practical reactors:

Important decisions about the future development of atomic power must frequently be made by people who do not necessarily have an intimate knowledge of the technical aspects of reactors. These people are, nonetheless, interested in what a reactor plant will do, how much it will cost, how long it will take to build and how long and how well it will operate. When they attempt to learn these things, they become aware of confusion existing in the reactor business. There appears to be unresolved conflict on almost every issue that arises.

I believe that this confusion stems from a failure to distinguish between the academic and the practical. These apparent conflicts can usually be explained only when the various aspects of the issue are resolved into their academic and practical components. To aid in this resolution, it is possible to define in a general way those characteristics which distinguish the one from the other.

An academic reactor or reactor plant almost always has the following basic characteristics: (1) It is simple. (2) It is small. (3) It is cheap. (4) It is light. (5) It can be built very quickly. (6) It is very flexible in purpose ("omnibus reactor"). (7) Very little development is required. It will use mostly “off-the-shelf” components. (8) The reactor is in the study phase. It is not being built now.

On the other hand, a practical reactor plant can be distinguished by the following characteristics: (1) It is being built now. (2) It is behind schedule. (3) It is requiring an immense amount of development on apparently trivial items. Corrosion, in particular, is a problem. (4) It is very expensive. (5) It takes a long time to build because of the engineering development problems. (6) It is large. (7) It is heavy. (8) It is complicated.

The tools of the academic-reactor designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone can see it.
Even more impressive are the combination washing machine and drier machines that dry and then drain the accumulated water via the washing machine plumbing without you having to ever empty it.

At least that's what I think my Hotpoint does.... it does get mighty hot and release a rubbery sort of smell when it's drying; my wife can't smell it but to me it stinks.

Clever equipment though.

Or, at least put it into a per-capita number. Normal flu season in the US is 40K+. Heart disease is. Cancer is. Auto accidents. Opiate overdose deaths. The population of the us is 18 X that of Sri Lanka, so all sorts of unfortunate, but non-collapse-level processes, hit numbers like 40K.
Can you supply more practical information about this device and why someone would put up with it?

A machine is an extension of its owner. Whips, billy clubs, guns, and knives don't get into trouble when they're used to damage or kill people. The people that use them are. The same logic would apply here. Why wouldn't it?

In the end all laws that would apply in this situation (unless OP provides more information) already exist and have existed since the first written laws.
Due to the situation we have to play remotely. The latency is fine if you are close enough (same city). We’re using jamulus as self-hosted, but you can try Jamkazam as well.
This gives me a great idea for an energy-saving air conditioner. It's just a white noise generator chip, a power amp, and a speaker. It'll be super lightweight to boot!
> Those who are interested in the email content and still have images turned off are rare in practice.

How do you know this? Maybe you keep kicking them off your list and are misinterpreting your signal. What percentage of your addresses never phone home?

I think this is the point of the post as people assume this functionality works and make decisions.

It seems like a low cost to maintain people who subscribed but never loaded a tracker image.

Not sure your product, but I think people who turn on this feature are savvier than some users. So pruning them from your list would remove potentially lucrative customers.

I think this availability bias of data leads companies to doing some weird, suboptimal things. Like using Facebook in place of market research leaves out non-Facebook users, etc etc.
This looks incredible! Has some serious offerings against the current Self-Hosted PaaS scene, hope I can check it out over the weekend.

I have used Dokku[0] in production, and played with CapRover[1] on hobby projects. Flynn was like a better Dokku, before development died.[2]

CapRover is a great experience, and it's not a toy IMO. It nails the role of "I want to press a button and have a self-hosted Heroku, with a nice dashboard, auto-provisioned HTTPS domains, and be able to deploy a bunch of Docker images or Buildpack apps." A single-node $10 box can run a good number of services.

This looks well-positioned and closer to something like Nomad, but going through the readme I had a few questions:

"Apollo requires a manager- or control-node. We call this manager-0. This node runs the entire controlplane and monitoring stack for a cluster and should be sized appropriately (8GB Memory, 2-4 vCPUs)."

Is there a way to run this single-node and disable some of the peripherals for cheap/play $5-10 instances (disregarding best-practices)? An 8GB mem + 4vCPU DO droplet is $40/mo. Not an arm and a leg, but if you have to add at least a secondary server, seems like minimum would be ~$50/mo?

"Your space has been created. Now let's cd to its directory: cd $HOME/.apollo/.spaces/demo-1.space"

Are the Apollo Spaces not meant to be checked in to version control and used for infra + shared between people on your team?

And final question (sorry if this is dumb):

Automated infrastructure (currently only DigitalOcean and HETZNER Cloud supported)

Does this mean I can still deploy to AWS/GCP, I just need to do it manually, or are these infrastructure templates required?
