Luckily, there's plenty of carbon to offset (peakers) by deploying batteries before we have to worry about long term (seasonal) storage.

However, I wouldn't be surprised if the electrification of transportation ends up making batteries be the default "long term" storage option by using EVs as flexible grid storage. There's going to be 100x more batteries rolling around than what you'd need to stabilize the grid (e.g. peakers), so I wouldn't be surprised if the grid asks more from EVs than just stability so it doesn't have to spend the additional capital for seasonal storage.
Absolutely spot on. Banks love inflation because it allows them to arbitrage between the CPI and the rest of the economy. Also the higher inflation, the more valuable a bank's services become.
GEB is a scam book that causes undergraduates to annoy their mathematical logic professors with meaningless questions
If someone commits a mass killing with a gun, then it becomes a mass shooting.

Frankly speaking, it's not clear what this thread is about. According to social constructivism, social reality might change by re-defining terms like "mass shooting", but according to my sense of reality the number of victims doesn't change at all. I can also see no reason why Wikipedia shouldn't base their lists on the 'most official' terms rather than making up their own, as long as they make clear that this includes multiple homicides by gun, which they do.

I think you're missing the point I'm making. Sure that team has a lot of experience running one of the biggest shows of all time, but they're toxic to lots of people who watch TV right now.

It was a bad PR move, and it makes it easier for spiteful fans to cancel their subscriptions. Normally just one of these things wouldn't be a big deal, but it seems like netflix has had a bunch of these "a bunch of your customers are so mad that they're leaving" events back to back.
Sometimes I wonder if news organization run these kinds of stories to reinforce the "scientist are clueless" angle and further sew our mistrust of science. Don't scientists have dogs, too?
Slack does (or did?) exactly this, I think. Each Slack workspace is its own deployment: its own web server, its own database, etc. This is loosely why accounts aren't shared across workspaces, you need to open a new tab per workspace, and so on.

What this forces you to do is to get really good at configuration management and orchestrating deploys, so that when something goes wrong, you can fix it for all your customers at once. You can't treat any single instance as a thing that it's meaningful to log into (you might still want to log into things to debug problems after a customer report, but making changes is infeasible, and ideally you notice problems before the customer report so you have to be aggregating logs/events/metrics). So many of the same maturity lessons as required for building a single scalable instance continue to apply to you. The distinction is that you don't have a giant distributed system, and you don't have the corresponding operational burden of a giant distributed system, so you avoid outages like https://monzo.com/blog/2019/09/08/why-monzo-wasnt-working-on... . (To be clear - this isn't meant to shame Monzo, that was a genuinely difficult problem and a genuinely good incident response. But there are advantages in not having a single company-wide database that runs everything from your core business function to your customer support chat.)

One of the engineering lessons I've been learning of late is you really want to avoid distributed systems wherever possible. They're cool, but the amount of engineering / operational effort required to get to a certain level of consistency or availability is way more than the effort required to get to that level of availability of a non-distributed system. It's fun as an engineer to solve hard problems, but it's better for the business to not have hard problems in the first place.
Anything that involves volumes and abundant resources.

E.g. storing hydrogen or compressed air in a salt dome decouples the power rating of your storage (MW) from the storage capacity (MWh). Similarly hydroelectric dams contain water by volume but you only need to dam a cross-section of the valley.

If this prediction turns out to be true, it would be a real boon for reducing carbon emissions. Changing from 7% to 40% of electrical generation is a big deal. I'm sure it's not enough, but it sounds like a start.
OK, devil's advocate here. Intel wants to segment it to make money. Perfecty rational, right?

Also consumers want it that way as ECC needs extra bits and run a few percent slower. If gamers are willing to overclock their CPUs then they probably don't much care for slower memory. And $cost.

I agree with you, but others have different priorities.

The author does link this video in the article; really a cool talk!
This particular missile's boost stage is based on the upper stages of the Minotaur-C rockets, which uses Orion rocket motors. Orion rocket motors are solid rocket boosters.

In general, solid rocket motors consist of particles of fuel and oxidizers suspended in some sort of plasticy/rubbery binder. These binders are usually some fun complex polymer. The Orion rocket motor apparently uses a form of polyurethane - which produces hydrogen cyanide gas on combustion.

Desirable properties of binders include: having a liquid form that can cure into a solid form in a controlled way (this makes manufacturing the suspension easier/possible), curing into something that is somewhat elastic/rubbery (I suspect easier handling, and more stress tolerant), and ideally also somewhat usable as a fuel (so that it's not a dead weight). I suspect that most polymers with those properties all have nasty combustion products one way or the other.

Some things to consider - most rockets, especially interceptor missiles spend most of their time NOT being fired. They are being stored and handled and tested, but not fired. That means that when considering your choices, you can't just blindly select for exhaust toxicity + rocket performance - you need to consider the operating cost and safety as well.

Its for this reason why solid motors are a go to - they are much easier and safer to handle than liquid fueled rockets throughout operation. They also have the desired properties in that they are effectively always ready to launch - you don't need to worry about managing fuel tanks or whatever.

I was just thinking the other day that we need to have e-ink based license plates. The plate number could be generated and changed every n minutes. There would have to be a government run system that would be able to link the generated number to the owner of the car, but hopefully there'd be some checks, balances and logging on the use of it (ie: a warrant would be required, etc). It wouldn't prevent a government from abusing it, but at least private companies scanning activities would be rendered null.
>This past week a woman yelled loudly about stabbing Mitch mcconnell in the neck outside his house as part of a large crowd.

Presumably people protesting against Putin or the people from Tiananmen Square weren't all asking for peaceful elections, I bet there were some protesters among them who were literally asking for Putin's or Deng Xiaoping's heads, that's what I meant with "vigorously protest". It's understandable that some people in the US would want to "vigorously protest" against people who they think are directly liable for other's people deaths, as I presume that lady thinks of the likes of Mitch Mcconnell.

As per the NSA mandate and the "civilian oversight", that's what I meant with "right at this moment". I think what you're describing was generally true until 2 or 3 years ago (yes, even after the Snowden leaks), but I'm afraid things are not the same in the current political climate.
Short term solution: natural gas peaker plants could be repurposed to provide power during lulls in production (better than most fossil fuels, but very expensive and still produce greenhouse gases, so can't be the solution for long)

Medium term solution: long-distance transmission, overprovision, and even more grid-scale storage (whole continents don't get cloudy & calm at once for long periods of time)

Potential long term solution: space-based solar (power is 24/7, just need lots of landing locations + distribution, because microwaves are attenuated by atmospheric moisture)

Edit: tl;dr is that for the issues, there are many potential solutions
The question is not whether it is, it's whether it could be.

Here's an example: the stock exchanges also need to handle huge amounts of concurrent and real-time data (with much greater constraints on latency and correctness and linearizability than Uber's customers demand). They're not running on literally unchanged 50-year-old tech any more, but they're also not doing the sort of technology innovation that Uber's doing, and they're doing just fine.
Also Porsche are fairly well known for being very conservative with their published 0-60/62 numbers.

Da Vinci's predictions of a helicopter weren't looking too good 170 years ago either. The history of flight in general is a great story of old dreams becoming reality.

And the dream has a simple origin, we knew birds could fly, so why couldn't humans?

The Industrial Revolution posed a similar question, if machines can do some kinds of work, why can't they do every kind of work?

A cynic would ask, what happens to the workers when there's no work? But I suspect the scarier question is, what happens when there's not enough work for everyone to be employed?

And modern transportation creates another question of what happens when the remaining work is happening elsewhere?

I really doubt nearly all iPhone users use iCloud. The ones on Hacker News might. I think a regular person would just shrug at prompts to set it up.

Lawmakers tell FBI it's too late the dead don't come back to life, and ask what the fuck were they all doing before the massacre given all the warning signs (regarding both the shooter and the readily availability of firearms for purchase)...
Back when "Silicon Valley" meant hardware and production lines, the practice was to shut down entirely for at least a weak between Christmas and New Years, in cases two, as 1) operating the line with short staffing increased errors and costs and 2) stopping and restarting the line incurred large losses as well of material in start-up and shut-down phases.

Better to entirely curtail ops for a couple of weeks.

That tradition had largely continued to manifest even with the offshoring of wafer, disk, and chip production, through the 1990s and aughts, though it's been in a slow fade for a long time.

Service industries operate on a different clock, of course, but a scheduled downage can still be communicated.

The two needn't be mutually exclusive. Someone could have been enticed to look the other way. He could have had materials made available which he properly shouldn't have, etc.

Now I'm not claiming any of these things, but I can see why there's going to be a field day with this one. That everyone saw it coming should have made it less probable, not more.
I know this is anecdotal, but I often ask this to drivers who used to drive for cabs. 9/10 they say they prefer Uber/Lyft because of their ability to set hours.

Though, that was mostly a few years ago when a lot of the drivers came over.

Lately I’ve heard a lot of complaints about their commission percentage, but fewer drivers who used to drive cabs, so I’m not sure how they feel in comparison.

>In the US, there are more firearms than people. About one-third of all households have at least one firearm

Nothing than

1) a total banning of sales,

2) a law that requires existing owners to return them for destruction,

3) 5 years jail minimum time for anybody even seen with one (and 20 years if they were involved in any criminal act while carrying it, regardless of the act),

4) and a mass confiscation campaign can't fix...
Is the argument that, without access to his phone, they can’t stop this guy from killing more people?

Is it that they need the phone to tell them that white supremacy and assault rifles are things that exist in the US?

Do they need the phone data for a conviction?

I don’t understand what they expect to do with whatever they find that they can’t get from other sources.

They can get location history and a pretty good idea what and who he communicated with from ISP and cell logs, etc.

The Morris Worm happened back when security was not really a big concern.

Memory corruption is much harder (and in most cases realistically not at all) to exploit beyond a DoS, and that's what you would get with "safe" languages such as Rust or Python as well.

Heartbleed, Shellshock, Dirty COW etc. would all happen exactly the same way in different programming languages.

Yes, there is clearly a benefit in using something which makes it much harder introducing memory safety issues, but it's not nearly as big as many here on HN think.

Better batteries allow lighter cars which allow smaller motors. It's pretty ridiculous to move a three ton object in order to move a single human, if you think about it.

The net amount to the public may be small. The scale offered relative to the size of the companies, and within high-value niches (enterprise customers, business partners, vendors/suppliers) may be significant.

Coordinated downtime can still be an advantage. It's actually a guiding principle in CPU scheduling systems as well -- so many cycles dedicated to processing vs. overhead.
Apsis
Yes, this has happened to several family members in the US, though thankfully mine was diagnosed properly because I could point to family history. Initially they wanted to write it off to migraines (I can't blame them since it's more common and can have similar symptoms at first) and now nine years later it's painful to use my hands and I've mostly given up martial arts.

It would almost certainly be worse if I hadn't had the family history to point to and actually convince them to do the tests that would confirm the diagnosis. For chronic illnesses defined by random irreparable damage the sooner you start treatment the better your outcomes are likely to be.

I am surprised that four doctors in a row did this, that's shocking. Usually a second or third opinion is enough that at least one of the doctors is paying attention.
It also helps that as a famous person one can take credit for other people's vision.

The trouble with those policies (aside from 100-round barrels... I have no idea what that means, and I don’t think you do either) is that they’re often-mentioned, but people forget to ask the question, “Have these policies actually improved anything where they’ve been implemented?” Many of the recently-publicized shootings in the US have occurred in California, which has some of the most strict firearms laws in the nation.

> We can reduce gun ownership
Do we actually want that, though? There are murmurs of defensive firearms use instances in the millions annually, whilst there are around 7k non-suicide-related deaths by firearm annually (1) (significantly less if you remove big anti-gun cities from the picture).

Compare firearms deaths with other causes:

* 70,000+ die from a drug overdose (2)
* 49,000 people die per year from the flu (3)
* 37,000 people die per year in traffic fatalities (4)
* 250,000+ people die each year from preventable medical errors. (5)
* 610,000 people die per year from heart disease (6)

There are a lot of things that might sound reasonable on the surface that the media likes to tout in the firearms debate, but many of them don’t hold muster. Why guns are the hot-button issue and heart disease isn’t plastered over the media 24/7? I think somebody has an agenda.

Short term = diurnal

Long term = weeks to seasonal

Batteries, especially that sort of cheaper battery, would be great for diurnal load leveling.

Long term storage is probably more hydrogen and mass thermal storage. The tradeoff would be capital cost per unit stored energy vs. efficiency.

Storage competes with and complements two other approaches: overinstallation of generation capacity w. curtailment, and dispatchable demand.

Curtailment involves installing more wind and PV than you need, and curtailing its output when supply > demand. A study in Minnesota found that this was cheaper than adding storage up to about 70% of the electrical power supply. Of course this creates dirt-cheap power during the curtailed periods that people can find use for (industrial thermal storage, production of hydrogen in low capital cost membraneless electrolyzers).

Dispatchable demand would involve redesign of industrial processes to operate in fits and starts. For example, today's aluminum cells do not respond well to inconstant power sources (their either freeze up or overheat and damage the lining). This was fine when the cheapest power sources were baseload sources. But perhaps an aluminum technology could be developed that would be more forgiving of variation and outages, to exploit the new situation where intermittent power is becoming the cheapest.

Of course, another approach is to move those industrial processes down close to the equator, where there is little seasonal variation in insolation. High latitude countries may become industrially disadvantaged in a renewable powered world.
Thanks for the clarification. I guess iCloud backups could then be a viable option then?
Every broken dream starts with a 3D render.
no, asking for sources is legitimate, it's a crazy world you live in where being asked to give a source for information is low value and/or low effort.
I'd guess easy hostability would be the main one, not anything technical. More hosting companies support PHP than any other language, and using it means people can set up their own file sharing system without needing to know much about server management.

That's arguably the reason most popular CMS systems run PHP too; because they'd rather have something that's easier to setup and can be run nearly anywhere than something that requires knowing how to use a terminal or something.
