Does a battery with low cycle efficiency actually beat hydrogen for seasonal storage?

The major problem with hydrogen is the fuel cell efficiency. Electrolysis is above 80%, but fuel cells are barely at 60% and it gets lower when you try to make the design more practical (lower temperature, less platinum). So batteries just have to hit 50% to compete. But that 50% includes both inherent cycle efficiency and self-discharge and Form Energy isn't putting their numbers up front, as far as I can see.

More importantly, seasonal storage is heavily concerned with heating, and the conversion of hydrogen to heat is a different matter. The batteries have heat pumps going for them, but you can make a gas-powered heat pump too. So rather than the fuel cell efficiency you look at the CoP difference between electric and gas heat pumps. The latter have received little attention, but could see a surge of interest if green hydrogen becomes more popular (and easier to transport). But here we exhaust my understanding of the situation.

What does similar quality mean, it they're different in multiple axes? Maybe one is easier to use but the other is faster, or one is better tested but the other is written in a more modular way that won't require big refactors to make changes?

This is the crux of the problem, I think, programmer output can be analyzed in so many different axes that have different weights in different industries that measuring productivity objectively is incredibly complex.

The EU parliament is hardly a group of developers. There are plenty of iPhone owners that want the freedom to run whatever apps they want to on their phones, too.

Further, I never said anything about what the "deal" was. I simply said that there are plenty of ways for Apple to make plenty of money without charging a per installation fee on every app that gets installed/updated on every iOS device.
In most parts of California you don't need active cooling at night. Just open all the windows at dusk and let the cool air blow in.

And then well insulated buildings will stay comfortable a good portion of the day too. Even during Sacramento 100+ heat wave I was amazed how cool a modern home can stay without A/C
> that could be interpreted as enticing phone usage while driving

This can't be true. Zooming the screen from the accessibility settings probably gets you half way there already. Every navigation app is enticing you to use it while driving. Touchscreens are enticing/forcing users to take the eyes off the road. The mere existence of the phone is enticing a driver to use it.

CarPlay "mode" would just be a slightly different GUI for what you can already do with the phone whether legally (by the passenger, or while stationary) or illegally (while driving). Every app in the phone is also accessible from the home screen.

At most Apple would have to issue a warning every time to use it correctly, like many cars already do.
That's not really their point, it's do we have any reasonable hope of applications that require the energy density of fossil fuels (flight) to be powered by electricity.

This was true if you don't co-locate CSS and code that uses it. Remove the code that imports the modular CSS and you remove the CSS. Interesting project nonetheless (even written in Clojure).

Kind of, ChatBot Arena was updated on Dec 7th, so hard to know for sure if Bard is just fine tuned against it.

That being said Chatbot Arena is a pretty wide variety of test scenarios. If fine tuning made the model perfect, all the small models would get similar scores to GPT4, which they don't. Essentially it ranks how people believe a ChatBot should respond, rather than just zero shot, 1 shot and COT type benchmarks.
Huh, firefox no longer displays that! I didn't realize that before.

Well, there is already discussion of the meaning of Measure 1) "take all measures within its power to prevent the commission of all acts within the scope of Article II of this Convention, in particular" part a) "killing members of the group", at https://news.ycombinator.com/item?id=39143094, so perhaps the confusion can be worked out there. I don't think it's as simple as "limit deaths" but perhaps I'm wrong, not being a lawyer.
Important to understand that Israel is not a signatory to the Rome Statute and rejects the ICC’s jurisdiction (neither is the USA). On the other hand, the Geneva Convention is about as “universal” a treaty as you can find, Israel itself ratified the GV without any reservations, all UN members (US and Israel included) are subject to the authority of the ICJ/World Court, and there’s even a fsir consensus that the GC applies to everyone, even if a state weren’t a UN member and signatory.

(While the USA and Israel have shown immense disdain for the ICC and the USA has levied sanctions against it, its chief prosecutor, and The Hague in the past, the US officially sponsored Khan’s nomination for the post of chief prosecutor this past round and Israel has been extremely chummy with him and the ICC compared to under Bensouda. The ICC under Khan hasn’t done anything about Gaza.)
Out of thin air...
if you're not hacking the immigration system, are you really an engineer??
Gemini was a bit disappointing on launch. Good to see them improving.

My own experience doesn't really match the arena's leaderboard. I find myself using Claude 2 much more than GPT 4/Turbo. I prefer its out-of-the-box response style, and its answers for my queries seem just as good, if not better.

Interesting, Kagi (where I use the chatbots) ranks Claude 1 as equal to (and faster than) GPT 4 (non-Turbo), and marks Claude 2's quality as on-par with 4 Turbo (albeit slower). Worth noting it's a simple 1-4-star ranking, unlike the arena's ELO numbers.
Also tech to be fair.

As far as I can see, it would be unwise to roll back 30 years of (Linux) systems building with dynamic linking in favor of static linking. It mostly works very well and does save some memory, disk, and has nice security properties. Both have significant pros and cons.

I've been thinking (not a Linux expert by any means) the ideal solution would be to have better dependency management: I think a solution could be if say binaries themselves carried dependency information. That way you get the benefits of dynamic and static linking by just distributing binaries with embedded library requirements. Also, I think there should be a change of culture in library development to clearly mark compatibility breaks (I think something like semantic versioning works like that?).

That way, your software could support any newer version up to a compatibility break -- which should be extremely rare. And if you must break compatibility there should be an effort to keep old versions available, secure and bug free (or at least the old versions should be flagged as insecure in some widely accessible database).

Moreover, executing old/historical software should become significantly easier if library information was kept in the executable itself (you'd just have to find the old libraries, which could be kept available in repositories).

I think something like that could finally enable portable Linux software? (Flatpak and AppImage notwithstanding)
Zionism is an ideology that took inspiration from the British empire. It was intended to be "something colonial" and pre-dated the atrocities of WW2. The fascist atrocities in WW2 can be interpreted as colonial tactics applied to Europeans, after all the British had been doing extremely bloody concentration camps in Africa and starved India during WW2. For some reason, Africa doesn't get the same play. I wonder why.

So people that engage in colonialism end up doing similar crimes. Israel remains probably the only old school colonial project in the present day with present day technology, backed by the U.S. empire to secure geopolitical interests in the oil-rich region among other things.

Something to think about: America is also a genocidal settler-colonial project and is one of the only nations to back Israel in the UN. Our genocide is still ongoing: visit a native american reservation and witness the immense poverty. Similarly to Gaza, the US state will simply say that despite being an occupying power, these are autonomous zones and we have little responsibility.
No, I wouldn't have published that headline, I would have put 'Some' in front of it, because that's the part that I could be reasonably sure of.
I suspect this will almost certainly lead to more companies that have policies against these tools. I'm also assuming data retention policies would be the same as email? Such that you can delete them, but it has to be a stated policy with legally applicable timelines.

We don't have billions of people living in the wilderness. And technology has reached a price level where off-grid solar is actually an affordable and superior alternative to propane and diesel for household use in rural Africa.
Sodium ion batteries are chemical and can have as much capacity as you like. They just need a bit more space, but not too much more, as they are already used in cheaper electric cars.

"Chinese automaker Yiwei debuted the first sodium-ion battery-powered car in 2023. It uses JAC Group’s UE module technology, which is similar to CATL's cell-to-pack design.[82] The car has a 23.2 kWh battery pack with a CLTC range of 230 kilometres (140 mi)."

And for grid storage, "slightly bigger size" really doesn't matter.
also, does "on your phone" include ("properly") hands-free, via carplay or android auto?
> after its people experienced the atrocities of World War II, would act in this manner toward the Palestinians.

That's part of why they're acting this way. Security fears. I'm telling you, the median Israeli isn't motivated by bloodlust or a desire for land, they're motivated by a high level of fear that they will one day be killed by Hamas/Hezbollah/etc. That fear causes them to demand complete "security control" of the West Bank and Gaza. That fear explains why they would not budge on allowing Palestinians an army as part of previous two-state negotiations. That fear explains why they would give back the Sinai but not the geographical high ground of the Golan Heights. That fear explains why the Israeli Left completely collapsed after the Second Intifada. They're happy to give part of the West Bank back in two state negotiations, but they would never, ever, allow Palestine an army. Because of security fears. The Palestine-Israeli conflict is this positive feedback loop caused by a desire for security conflicting with a desire for freedom. We're in the terminal doom spiral phase of this feedback loop right now.
Extreme slowness and bugginess are a pain, but what you're describing doesn't sound like the boot loops and inability to read from internal storage that people are describing from this update. I'd hazard a guess that you're suffering from something different.

Yeah, right. I know there's this tendency in America to worship Europe but I can't help but laugh when anyone suggests a democratic government passes laws that are going to improve security. "We're from the government and we're here to help."
The article discusses this: it’s often not obvious and largely on the honor system, just as police are often extremely deferential to drivers who claim a pedestrian “jumped in front” of their car. That means that we’re almost certainly significantly undercounting the number of times it’s a factor.

A good analogy would be DUI: Americans really loved their booze and there were many people who felt it was a core freedom to be able to drive after drinking, but eventually the death toll mounted high enough that our social norms changed to include things like designated drivers and doing roadside tests rather than trusting drivers’ claims. Phones will probably follow a similar arc because they are involved in many serious accidents and most people agree that driving safely is not an unreasonable request or a civil liberties violation.

Remember!?
Nice philosophizing, but too simple. There definitely are constants in the universe, and dynamic things can stay pretty constant over looong time scales, think of stars, or something complicated as a solar system.. and then it is about rate of change at all levels.. what's nothing for me is the lifetime for a fruit fly, and I live merely a split seconds of our Earth's age.

And then there are humans, always against change ;) But some is reasonable, e.g. when life threatening conditions change. I step out of my house in freezing temperatures, if I don't do something I'll freeze.. I don't start philosophizing about where to restore it to, just wanna be safe and warm again.

I don't get all the clever insights. Environmentalism is already such a stupid term imo, this is not about saving the environment at all, or trying to keep the world the same. It is just human warranted egoism, about saving us.
So your argument is that it is a proxy for use variability, and that determines how much the grid needs to be overbuilt.

I'm not sure that either of those are solid assumptions,but worth some thought.
2hp is 1.5kW. That's 5 to 10 times smaller than the units being discussed here.

I presume you mean WordPress.com here (WordPress = open source project, WordPress.com = product by co-founder of WordPress; it's confusing). They did run LiteSpeed a long time ago, but haven't in at least a decade; they moved to Nginx.

The twisty maze of parens I never understand. (And the fact that TI won is probably, imho, only vaguely to syntax, kids barely use calcs anyway, and I'd argue that if you'd show them RPL immense programming surface, lists, vectors, lambdas, they'd use it more than the usual fix function graphing calc)

I never had a chance to see proper CASE tools, my education started in 2000.. java/uml took the light and the few environments I saw were very very subpar (post IBM, eclipse based, rational suite).

The grammar composition is still a big open problem, I think Lawrence Tratt tried to attack it (maybe this https://soft-dev.org/pubs/pdf/diekmann_tratt__parsing_compos... ?) but concluded it was still fragile/difficult.
Well, given that it's on the front page of HN, now is probably the right time to play!

I don't see myself switching to an Android phone but iPhone updates do break things. Since upgrading to latest iOS, both my phone (personal and work) keyboards are unusable if I enable both English and Vietnamese keyboards.

My experience comes from around the same time frame -- I spent about a year on an aborted spectral dimension reduction project, and I only recently realized how similar the problem still is today.

The UN does not corroborate the accusations you levy against Hamas. Israel has (documented) killed hundreds of UN or general aid workers; to my knowledge, Hamas has killed none.
I view safe/stable power, clean water, and waste/sewage systems as bare minimum utilities that everyone should have. I don't live in a third world country and so equal access to those kinds of utilities should be a given for everybody. I really like the idea that everyone in my state is entitled to equal access to the grid and I'd much prefer to have people on the grid rather than having people in poor/remote communities trying to create their own shitty replacements with the dangers and fire risks that'd create.

I see no reason why people who don't live in cities should be punished or burdened with higher access fees, especially if those people can't afford to move/live elsewhere. It may cost a lot more to run utilities out to users in remote areas but it costs very little to run them to users in ultra-dense urban areas and that's where the vast majority of the users are so it should all balance out.

From what I can tell, there's very little of either of those categories represented here, at least not in any systematic way.

Based on what I've seen from people within Blizzard, there was absolutely no performance-based layoff here. This was entirely from a high-level "pick the roles you think you don't need anymore" perspective.

It's also not at all clear that it represents any meaningful consideration of who is "redundant" after the merger. A significant amount of those 9% came from eliminating the roles working on the canceled survival game.

I did hear that they also eliminated an entire customer service office in Texas—it's possible that was considered "redundant", but it's also possible they've just decided to outsource that particular bit of customer service.

No; as with many, many layoffs-in-good-times (which generally includes layoffs-after-a-merger), this is primarily just the people at or near the very top reaching down and slashing with big machetes and very little careful aim in order to juice the stock price.

Do you genuinely think that if you kill someone because you were driving on your phone, that information should be hard to access to an investigator?

Like, I understand that privacy is important. I agree that it is. But if you choose to drive a deadly machine, then you agree to give up a degree of that privacy.

All cars have license plates, identifying who it belongs to. Car drivers are subject to document checks by road security personnel. Car drivers are subject to alcohol tests if they're suspected of being drunk.

What makes phone usage more sacred than any of those things?

I'm not saying all your phone data becomes public if you're in a crash, the same way that an alcohol test doesn't tell the cops where, what, and with who you were drinking with.

How is society in any way worse, if phones recorded usage in the past 24 hours, and drivers had to provide that data if implicated in a crash?
