Individual projects? No idea. But Poland has a lot of mines, so a lot of room for gravity-based storage.

My suggestion is to build:
* 1 GWh capacity of those gravity-fed; and
* 1 GWh of concentrated solar heat storage — it won’t be as effective in winter but let’s try; and
* 1 GWh of Li-ion batteries; and
* 1 GWh of hydro-storage; and
* 1 GWh of liquid metal storage.

And see which one scales, and what cost, with what retention, reactivity, how is the maintenance. All should, there’s no reason a larger pile of rocks doesn’t retain heat any less well than a smaller pile, or that what you can’t get from one mine shaft doesn’t work in another mine shaft. If you think that’s too much for Poland, let’s try one in Arizona, Iceland, Australia, Kazakstan, Hawaii, and see which one works best and adapts to Polish climate.

I’ve never seen an inventor that didn’t iterate from a working prototype (which we have for all these) to a larger one, to a larger still, until they hit scaling issues. And I don’t know of currently salient scaling issues in any of those (that haven’t been addressed recently — there were targeting problems with concentrated solar that found a solution recently for instance).

“Will it scale?” isn’t the questions that an engineer would ask on any of those at this stage of the project, but rather: "How fast can we make one twice bigger?" When we hit roadblocks that can’t be fixed, we can ask about scale, but right now, all those have a clear path.

"Overbuilt" assumes that renewable capacity doesn’t adapt to winter condition but it might: cooler external temperature could mean that geo-power, or heat stored from the summer represent a higher differential, and more energy. Or it assumes that capacity is expensive, which has never really been the case with variable prices: not for gas plants, not for renewables that are not constrained by context.

If you are worried about European winter overall, that makes sense, but the solution for that is rather obvious — enormous, but so much cheaper than anything else comparable: giant capacities in North Africa, big cable through Spain and France. From there, the extra capacity in Europe can serve Northern Europe. Scandinavia continues enjoying their massive boost in renewable hydro in winter, and the winds in the North Sea will definitely need exporting too. “Windless winter” isn’t apparently a common thing there. That might require more international solidarity, but people will do that quite keenly if there’s money to be made.
I agree. Even being considered of doing something bad can easily be life-changing - going by the example of celebrities, for one. One of the secrets of the nothing to hide argument is, I think, that people haven't experience a thorough search on them, by some authority. The situation where one "lives or dies" according to what they find, and especially, on how they interpret it. If not exposed to this, it's much easier to think that it won't happen to them, that they're not the type to be exposed to things like this.

I liked this piece. Enough to log in and comment at least. It's the rare article where the author is open about his biases but gives an opposing approach an honest go. Reading three books about OOP is way more generous than I'd ever be. And when that approach still doesn't make sense, he offers a better one. Always enjoy reading the informed hater's perspective.
I was at an outdoor exhibition last week, and one of the staff called me out and said "No Digital Photography Allowed... it says so on your ticket"

Meanwhile, it feels like almost everyone is taking photos, videos and live steaming the entire thing from high-end smartphones!
Sounds a little sexist, maybe with good intentions. Maybe it's time to look for the best qualified candidate regardless of sex?

Improving your team's on-call experience
I quit early 2021.

Among other things, the fact that my employer was okay seeing me commuting 3 hours daily and paying it out of my pocket.

Honestly, I didn't mind the commute (first class train, direct line, time deductible if I work in the train, office 2 mins away from train station) but the topic of long commutes and their health impact started becoming regularly covered in the news. I began to realize I was being mistreated/disrespected. I shared my feelings with my manager and HR and they didn't offer me any support.

Along with the invisible career path, that was enough reason to quit.

I found a job a few days after quitting. Got a 10% pay raise + unlimited travel pass for the entire country + WFH/flex.

I miss my colleagues though :)
When you just say "delta-v", it means nothing to anyone who doesn't already know what that means, and it provides no additional value to those who do, so the comment has no purpose. At least a complete sentence like, "This illustrates why it's difficult to overcome the large delta-v between Earth and Mercury," would say the same thing in a way that could actually be useful to someone. Even better if it defined delta-v as well.
Airships would make a fantastic, greener alternative to a cruise ship. I suspect winds to be its biggest sticking point.
This sounds like an incomplete test. What was the control? Did they try sticking fruit flies to the stems of known non-carnivore plant?

Living in inhospitable environments is a choice, not a necessity, that is causing environmental degradation. Let’s say an ideal human environment temp is around 60-80 degrees. In 110° weather, you just need to move 30°. In freezing weather you’ve gotta move 48°. That’s 50% more delta.
Hey HN!

My name is Sean, and I'm a fractional CTO / full-stack developer. This is a project I joined up with a couple months ago. I figured the HN community would appreciate seeing our lean MVP.

We're solving that simple, pesky problem of oversized CDC vaccine cards not fitting in wallets (and getting torn to shreds in doing so). The web app allows you to scan your vaccine card, and we'll ship you a credit-card size plastic VaxCard that fits much better.

I'm happy to answer any questions (especially around technical and security details). I love sharing new products with this community (for some brutal honesty ;))!
If 3x+1 is a programming language, the Collatz conjecture must be false as otherwise it would always halt.

I suspect 3x+1 is not Turing complete.
You make a poor argument overall. Just because convenience will tend to win out doesn’t mean people shouldn’t choose more secure over less secure.

Your argument boils down to “govt can force them to change how they do that”, as opposed to a flaw in their approach.
Yeah, I don't drink during my oncall shifts either.
Easy one. My office literally has one above me called Pipeline Studios. It's not even the only one in my mid-sized city. Comparison is easily reachable. You just don't like it because it contradicts your bubble.
Continue using android. Was thinking about switching for my next phone, but I'll probably hold off and see how this plays out.
In that case, they're competing with trains.

> -Also, much slower and lower cargo capacity.

I've always found airships and lifting gasses fascinating, but I'm not fully educated on this point. I thought that airships could potentially have very large cargo capacity, especially because larger airships increase aerial stability. Speeds would be slow, but I thought it was feasible to ship huge payloads, no?
They had a much higher ratio during Barbarossa ;-)
Well, 3 https://youtu.be/VUgajGv4Aok Xyla Foxlin's video has the information about the proper ratio of wheel to propeller to make it all work.
Somewhat a side-topic in this article, but I found this sentence striking:

> When I'm losing, it's pain coupled with RAGE, depending on how bad the loss is, or how futile I feel playing.

This doesn't sound very healthy, and is kind of scary. What is this enraged person capable of in this state?

A feeling of RAGE (in all caps!) caused by a video game might be revealing some serious anger issues that (in my opinion) should not be left unaddressed.
I assume the worst consequence of publishing anything on the collatz conjecture is that you will forever receive kookmail from people who think they've solved it.
Nothing will happen, despite all the outrage. Unfortunately, it will blow over when they announce the M1X Macbooks and iPhone 13.

Given the many users who keep having a @gmail.com address, their privacy is already invaded by Google. Even switching off location on a typical Android device doesn't mean off. [0] Some people have to drastically flash a custom ROM to escape, where as most just won't bother.

As for the Linux phone ecosystem; they are not even ready yet. So for everyone outraged at Apple right now will just keep on using their Macs and iPhones as normal.

In A Philosophy of Software Design the author talks at length about this and proposes that "deeper" modules (classes/methods/functions etc.) provide the most cost/benefit ratio, where the interface of a module is the cost and the functionality is the benefit.

Code doesn't magically become less complex by hacking it into pieces.
Fire is part of the natural world. Trying to eradicate all forest fires tends to harm ecosystems. Some trees can't reproduce without fires opening their pine cones.

I'm really happy to see this research. I am aware that climate change is real, but "the news" tends to focus on bad things.

It was predicted that the Kuwait oil well fires would burn for years and be a global environmental catastrophe. When crack teams converged on the area from around the world and put them out in just six months, we did not party in the streets over having averted a global catastrophe.

That's part for the course. We routinely wring our hand about how bad we expect it to be, then take it for granted when emergency response exceeds our expectations and move on to whining about the next gloom and doom scenario.

I'm fully well aware that the next gloom and doom scenario is likely all too real and not neurotic overactive imagination at work. But it just sucks the oxygen out of the conversation when people act like it's crazy talk if you aren't part of the "We're all gonna die!!" environmental belief cult.

Me thinking there is still hope, we can still find solutions, we aren't all doomed is not evidence of insanity, stupidity, cluelessness or denial. I'm an environmental studies major. My father fought in WWII. The entire world was doomed then too and survived.

I know we need to somehow get people to take things seriously and actually take action. I just don't think emphasizing how utterly doomed we are is the way to do that.

For lots of people, that will make them go "Why bother? We're doomed anyway. Me being all self sacrificing won't fix it. I might as well enjoy myself a little before we all die and this world turns into a smoking husk."
At first I intend to do nothing, and stay on iOS 14.

Then, I intend to sit back and watch the show, and see how it shakes out. I don't really expect much to change from Apple, but if anything does it's going to take time for it to happen, and it'll take time for any alternatives to surface.

Kusenko "conceded on a technicality — that the vehicle moves marginally faster than the wind temporarily," Cavallaro said. "I offered him another $10,000 bet, because his technicality is entirely wrong, but I know I won't be hearing from him."

Can anyone explain this line's reasoning?
I thought this said "new coronavirus plant".

If it's this difficult to get folks to transition to lower energy-use regimes, I think it would be even more difficult to get folks to abandon growth-based economics. Unless the worst happens and our economic systems collapse due to climate events. That's what I would consider the worst case, though.
I guess the ending is supposed to be a joke, but because the piece never explains what | means, I couldn’t figure it out.
Melatonin is not recommended for sleep. A better combo to take would be 200mg L-theanine and 500mg Magnesium Threonate. Melatonin can disrupt your natural melatonin production and those supplements are also notoriously inaccurate in terms of dosage some containing anywhere from 0.2x to 2x the amount listed. Melatonin is probably acting more as a placebo for you now.
Yes but why is that a valid reason to shift goalposts? What is the endgame?
When you say OEM switches, what exactly do you mean?

I've been trying to get the perfect setup and the Lutron LZL-4B was pretty close, but they've been discontinued and are hard to find for under $100 / switch.

The RunLessWire switches don't use batteries, which is a negative for me. To use them you have to push the switch oddly hard, so when visitors don't press it hard enough they assume the lights are broken.

The Philips Hue Dimmer would be *perfect* if it fit a standard light switch opening. But it doesn't, and I'm not going to stick an extra fake-looking outlet to my walls.
Efficient Air Water Generator to Debut in September
Except that they will be in situations different from a person in their home defending against an invader. They will need accuracy and effect at 50 meters, you only need 5. They will be laying down cover fire to allow repositioning etc.

As far as accuracy goes, a rifle’s size might be an issue in close quarters. And once you’ve fired off a few rounds, even if you missed, the intruder now knows you have a loaded gun, you might land the next shot, and the neighbors are allready calling the police.
It is more than just having the toolbox. You need to know how to use the tools and know how to combine them . Anything harder than the basics is going to require a lot of outside the box thinking and epiphanies rather than just pattern recognition

I used to work in a building with a drosophila fly lab. From time to time, I'd visit the lab, use CO2 gas to knock a fly out, and then place it in my venus fly trap (you have to flick the little hairs in the trap a couple times to get it to close). The fly wakes up, and since it's alive and jiggling, the trap stays shut. About a month little the trap opens again, and a little husk of dessicated fly drops out. Afterwars, the plant grows nicely

Intel Fully Embracing LLVM for Their C/C++ Compilers
The author seems hung up on the idea that because NLU involves apparent "discontinuities" -- places where small variations in interpretation completely transform tasks -- it will not be amenable to smooth, continuous notions like PAC learning, compressibility, and so on. While there's a directional insight there, the terms aren't well defined. And the big story of ML-based NLP in the last decade has been that many tasks that were presumed too jagged for curve fitting are in fact tractable, given large data sets and clever shifts of the way discontinuities can be modeled (e.g. attention-based techniques like Transformers).

Finally, since humans don't perform perfectly at these contrived tasks either, we must ask acknowledge that there is some degree of "approximate correctness" that satisfies our ideas of intelligence.
That only works if the landlords who are "in on the game" own all the houses. If they only own half, and people double up, then the landlords who are trying to play this game end up with $0 income for their investments. That's going to be painful - hopefully painful enough that they have to abandon the strategy, and we can return to sanity.
> However, language understanding does not admit any degrees of freedom. A full understanding of an utterance or a question requires understanding the one and only one thought that a speaker is trying to convey.

What a laughable claim. By this definition NLU is easily shown to be impossible by the existence of ambiguity in natural language.
it would also be a very beneficial way to plant them since corn and squash are heavy nitrogen feeders, and beans are a nitrogen fixer.

It seems a strategy that might work is pairing the carbon tax with a universal refundable tax credit such that it's revenue-neutral. That way people can pocket the difference if they want to use less carbon.

I haven’t clicked the links to see if it’s mentioned because mobile, but it should be more than plausible - it was done 80 years ago; the Graf Zeppelin hydrogen lift airship did a round the world flight in five stages in about 15 days total flight time in 1929:

https://www.airships.net/blog/graf-zeppelin-round-the-world-...

(And it was the first air vehicle to pass 1,000,000 miles travelled, with no accidents, the first to reach the North Pole, the first regular transatlantic commercial flights, etc. all with 1920s technology and tens of thousands of hand-glued animal intestines for the lift bags)
Agile Armageddon or How Scrum Will Finally Burn in a Fire
If my job wouldn't be in the IT field, I would be certainly be able to live without the internet. You can live without the internet, as does billions of people in the world.

My grandma never had a computer, or a smartphone, she doesn't even know how to say the word internet, and still she lives fine, and she knows more informed than I that use internet, reads newspapers, on paper, without stupid ads, listens to the radio, watches TV, calls her friends with the landline phone, and most importantly, a thing that nowadays is lost, she goes outside and talks to people.

It seems like we no longer can talk to people, we are constantly busy with our devices, back in the days if you were on a train what could you do, read a book, or talk with the people sitting next to you, nowadays you use your phone, listen to music with headphones, and isolate from others.

Internet was a great thing, but the internet of the beginning, of the '90 and first '00, where it was a cool thing, where you could have used it to learn new stuff, the internet of IRC chats, the internet of forums, communities.

The internet was good because it was something alternative to the real life, something you did in the evening when you didn't have other things to do, nowadays internet became a substitute of the real life, on the internet you share things you do, you talk with people that you know in person, and then when you meet what have to say since everyone knows everything others have done thanks to social media?

Also in the modern internet privacy is destroyed, back in the days one rule was never use your real name on the internet, and never share personal information. Now it's the opposite, Facebook requires you to use your real name, YouTube wants your ID to watch age restricted videos, they encourage you to share to them all your personal information, that is bad.

I wouldn't return to the days before internet, but I would return to the '90, where internet was something good, and just a cool tool you could have used, but not something fundamental for your life.
Bundling is still required to avoid HTTP waterfall that would ensure if you load raw ES modules from the browser. A real-world frontend codebase will include 100-1000+ files (via transitive dependencies), and you do not want 100+ sequential HTTP request even over HTTP2.

You might not need to transpile your app (via babel), but you still need to bundle it (via webpack/rollup/parcel/esbuild/swc/etc)
Yes, that is what I meant. Greenpeace doesn't like nuclear and they don't call it green.

I typically consider nuclear to be green, but I wanted to understand if other people (not including Greenpeace and organizations like them) agreed that it is considered green.

Yes. It always has to have a much larger surface area in proportion to the weight it is carrying than any heavier than air craft, by definition.

That means it has to have more volume to lift more weight. More volume means more surface area (though not linearly!). More surface area means more impact from strong winds, updrafts, downdrafts.

And we haven’t figured out any plausible sort of propulsion that can even momentarily provide enough force to counteract something like a strong sudden downdraft without being too bulky to be practical.

-Building? That’s just bricks, old fashioned.

-But we can build with concrete and steel and plastics and all sorts now.

-Most people use bricks though. And people are not tearing their brick houses down to rebuild them in steel. See? Building is old fashioned, antiquated!

In fact, nobody now starts a new project in F77. There’s a lot of F77 brick code around, yes. And it still does the job it was asked to do even though it gets moved to a new district every ten years.
It's probably not obvious to people outside the community, but the amount of effort that's currently going into MTK and the larger SciML stack is absolutely enormous. Depending on how you count, maybe an order of magnitude more than is currently going into Julia proper. By my count at least 30 talks at JuliaCon this year were about SciML applications. That whole ecosystem is really taking off.
Thank you for the great summary.

However, Flash was really easy to get into. You didn't need any programming whatsoever if all you wanted was a vector cartoon. And you did need to copy-paste some ActionScript if you wanted a fancy-looking navigation bar. Current web lacks this ease of authoring, so I wouldn't say "you can now do everything you could do in Flash".

Flash also felt more like a proper application framework. Web still feels like you're working with an extremely advanced word processor.
