Seasonal storage and thermal batteries are pretty easy and cheap to construct. The materials tend to be cheap commodities. All you need is space to construct them and a way to produce the heat you use to charge them.

For example, I know of an experimental setup in the Netherlands called CESAR (https://materialdistrict.com/article/battery-natural-stone/) that uses basalt rock. The basalt is heated up using solar energy in the summer. It is stored in an a metal box insulated with wool that apparently retains heat for months/years. Long enough to last the winter. You 'discharge' by pumping cold water through it. Warm water comes out. Very simple. It has been running for a few years and it seems to be cheap and work as advertised. Relative to burning gas, this looks like a nice idea.

Converting heat to electricity is more tricky and the efficiencies tend to be not great. Of course if the storage is cheap enough that might not be that big of a deal. Efficiencies are also a challenge with geothermal energy. But it's a great solution for heating buildings. This particular solution seems to work around this using molten salt which allows for a relatively large temperature gradient. But without having to drill kilometers into the earth's crust.

Probably over time, cost will decide which solutions end up getting used where and how. A good insight here is that different storage solutions serve very different purposes. You don't use lithium ion for seasonal storage. It's way too expensive for that. But it's great for short term grid balancing needs and seems to be popular for that. Vice versa, thermal mass would be probably bad for balancing the grid it's great for storing lots of energy that you use up slowly during the winter.

It's a tradeoff between how much energy you need stored, how much space you have for storing it, and how quickly you want to charge/discharge. It's telling a lot that a relatively expensive solution like lithium ion batteries are actually cost competitive with things like gas peaker plants. We can do probably do better long term. There is no shortage of good & already validated ideas in this space. All we need is good old engineering and manufacturing to prove products in the market at scale.

Yeah this isn't how contracts work. You don't get to say "what do I know, it was prepared by an attorney".
It's remarkable and humorous how it's just a gun. Like this is how the Victorians would have approached fusion.

More power to them! We need to test a myriad of approaches. This could well turn out to be the best one.

Personally I think that Gibson is vastly superior to Stephenson.

As for recommendations about post-cyberpunk: our own cstross has written plenty of great books (Accelerando in primis); I've liked anything that Peter Watts as written so far (Blindsight is the most famous, but the rifters saga is also good and the Sunflower cycles is excellent). Alastair Reynolds writing is very uneven, but world building is excellent and so are many of his stories (even outside of the Revelation Space universe).

More generally, Egan (hard sci-fi), Banks (space opera) are some of my favorites. Vance, Wolfe for something more on the fantasy side.
If that app had a "support" link on every page that would pop up a form, pre-filled with recognizably sane defaults that provide the context of the support request, I'd wonder about that user to.

If I had to hunt down "support" somewhere under "about" in the menu or if I was presented with a very generic form, I'd be that user because I'd dread the braindead support conversations I have learned to expect (Seriously, just today a hoster told me to send them a screenshot of the HTTP 504 response their customer UI receives for a javascript request to their ticketing system.... to support@....)
Depends on the person, doesn't it? If I were at Twitter, I would be excited about this. I would be expecting the work to become more challenging, but also more important.

There was case law before s.230 was passed, which said what parent claimed: if you moderated your content you carried liability as a publisher, if you were careful not to look at what went up on your service then you didn't. s.230 was added to the Communications Decency Act specifically to remove that perverse incentive in order to encourage 'family friendly' moderation. That's it. It doesn't anywhere require good faith. The entire legislative history is on record. And it long predates Twitter.
I find this to be incredible news. I used to think Elon-hype was stupid, but both (a) his achievements and (b) his mind have gotten me to be an admirer.

Re (a) achievements, the man has basically bootstrapped space travel and electric vehicles. Seems like a big deal. Yes, I know it's more nuanced than that, but you get the point. Can you name someone else who broke through two fundamentally stalled/deadlocked industries on such scale? Now here he is putting his plow to the field of one of the most difficult problems of our age: information and social media.

Re (b) his mind, I have been very impressed by his interviews on podcasts as well as his willingness to go on various long-form podcasts. He seems to be somebody who is very eager to learn about a great variety of fields (history, software, hardware, physics). He also seems to take great care in extrapolating side-effects down a chain of events in order to think in a complex way of "what would happen if we do X". The world is not black & white and Elon seems to operate very comfortably in known & unknowns.

I don't agree with everything Elon says or does. But it's so bloody stupid that I have to even say that. What sort of bubble do you live in where you actually have various people who you fully agree with across all spectrums? Get out in the real world for goodness sake.

We need more Elon Musks.

Addendum:

Respectfully - Ingress is by Niantic, the same company behind Pokemon Go (and maybe that Harry Potter version?). They share data between the two games - points of interest tagged in Ingress still usually map to Pokemon Go Stops and Gyms; energy (can't remember the name for it - the golden energy you collect by walking near) usually maps to individual Pokemon spawn locations. They get their raw map data from OpenStreetMap; I'm not sure if anyone knows where they get their specific data on user/internet use density which informs some of their map features, but Google GPS analytics is probably a fair guess.

I used to play a lot of Pokemon Go, but plenty of things made me drift away; as for motivating me to walk, it kinda helped, but really just ended up with a lot of "walk 300 ft. (~100m), stop and stare/tap at your phone for several minutes", vs. the more enjoyable and directly beneficial (towards distance/time/step goals) uninterrupted pattern.

Yes. The public can choose to create a legal structure that does not let private entities grow so large, but we have not chosen to do so, and that choice does not mean that private entities are de facto public.

Companies should be required by law to give you a notebook computer or both a desktop computer and a notebook computer.

He believes in his free speech. Maybe. Definitely not when it comes to people who work for him or people that criticize him.

By "shield himself from the consequences of his activity" I think Elon literally meant "I don't want to get shot by some crazy person following my movements". No perfect solution, but I can get his motivation.

There's a MOOC[1] on it, and there are several free books that cover the basics of the language itself[2][3], data visualisation[4] and numeric stuff[5].

Bordering countries like Italy and Greece were becoming overwhelmed by migration wave. They were crying for help for quite some time til anyone even noticed the problem. So to ease the pressure there was plan to redistribute them in to EU. This was refused by several countries so 'Merkel' took some of them to Germany. It was not ideal but better then nothing.

That crisis was caused by instability in Middle East. Which was caused by several other factors like climate (farms without water in Syria) and international politics of Russia and USA. But like now everyone was blaming Germany.
I definitely agree with "letting go of the past". Notes and memories are important, but so is managing what you keep. Otherwise it becomse untenable.

Anyway, I made a show HN today, but it's kind of relevant (https://news.ycombinator.com/item?id=30917504). I made a notes extension for taking notes quickly and in the moment, before you decide to keep it or that you're done with it.

Neuromancer was a critique of the era that birthed it. Reagan might be gone, but the frameworks cemented into place back then are still the same frameworks we operate under today. Gibson may have unintentionally been predicting the future. As the world further aligns with the cyberpunk dystopia, the mainstreaming of cyberpunk aesthetic is inevitable.

I'm reminded of that line in The Matrix when Neo breaks The Oracle's vase, "What's really going to bake your noodle later on is, would you still have broken it if I hadn't said anything?"

Honestly, this sounds a bit like some of Philip K Dick's work, which was set in the Bay Area after a nuclear war... he wrote it about 50 years before Gibson, though I'm sure Gibson must add something original to the mix.

I once asked Gibson whether he was influenced by Philip K Dick, and he said that he didn't read Dick when he was young, and was more influenced by Pynchon instead. Still, despite his denial, he seems to be retreading a lot of ground first covered by Dick himself.

The damn 'burbs. Nothing to walk to, everything's been spread way too far apart. Maybe a park or neighborhood pool if you're lucky. Too much non-place taking up space between places is killer. Literally, given heart disease.
I get your point, in fact, I don't put a lot of effort in getting things organized to any degree of "good". I "invest" in archiving (I almost never wipe a memory card, a floppy disk, or a hard disk, I just store it. I do copy CDs into hard disks though). If I had, let's say, two months just to organize the data, I would, and to me, it would more than compensate the time doing it. Every time that I had to look for something I had done 10, 15, 20 years ago I find, in the process of searching for that specific thing so much gold, so much joy, that it paid off. But of course, I do not obsess with categorization. I have two axis: the "technological age" (dictated by the kind of storage device) and the way I categorized it then within that device. I think I have been more or less consistent with how I name folders, where I put things, etc. over a long time.
Or for Elon Musk, depends who you ask. HN is't a person's initials.

Show HN: Flight Penguin – Like Hipmunk, but a browser extension
Hi HN! I'm Adam Goldstein, co-founder and CEO of Hipmunk (YC S10). Today we're launching Flight Penguin (https://www.flightpenguin.com) in public beta as a browser extension for Chrome and Chromium browsers.

Hipmunk was a travel metasearch site that sorted flights by "agony" and showed them in a Gantt chart view. I've missed using Hipmunk ever since SAP shut it down. So I decided to seed-fund a successor along with my Hipmunk co-founder (and Reddit CEO) Steve Huffman. More recently I brought on Max Morlocke (hn: maxmorlocke) as cofounder.

With Flight Penguin, you get a simple, time-based way to search for flights, and it pulls in results from multiple sites. By default Flight Penguin sorts by "pain," so you see the least painful options before the multiple-layover monstrosities Kayak loves to show first.

As some of you know, some airlines are now demanding anti-consumer provisions when they do deals with travel sites, such as insisting that sites hide cheaper flights, hide multi-airline itineraries, and hide certain booking options. We decided not to agree to any of those terms, because we want to make the best experience. Being a browser extension gives us the ability to show the lowest fares without going through airline servers or airline contracts, since we can search and compile all the data from your browser.

You can install it now at https://www.flightpenguin.com. We're also launching a crowdfunding round to keep our incentives aligned with our users: https://wefunder.com/flightpenguin. Happy to answer any questions and would love your thoughts!

1) > (Oh, and to address your specific point, the designers spend exactly zero hours watching training and tutorials on the Adobe website).

Yes, most of the time when you know your tools you will not spend much time going through training material, but if you needed to there are plenty of options and not just from Adobe. If you want to learn and get started there are plenty more options.

2) > I know the open-source evangelists live in a rose tinted world where open-source automatically equals better.

I don't recall stating that OSS = better, but in many cases it is. RawTherapee may not be as easy to use compared to Lightroom of Capture One but if used properly you can achieve superior results. One closed source RAW processor I can think of that lacks much training material but achieves great results in Raw Photo Processor (better than LR of RT in many ways). GIMP is great but until they can implement Adjustment layers it will never be a good alternative to Photoshop. IMO PhotoLine is much better than Photoshop in many ways, but also lack much training material or a large budget (being developed by two brothers in Germany). I can keep going.

I should add to my original comment that the amount of training and getting a product out for users to use is major for a company to succeed. Adobe and Microsoft have done a great job at getting their products in front of students and making sure they are comfortable with their products before going into the working world.
Did they ever get around to building a stable OpenXR toolkit? It seemed like an afterthought last time I checked..

Liking Twitter and thinking Elon Musk ruins things certainly are tightly coupled.
I know you didn't ask me... but I'd say "Get one." The benefits far outweigh the deficits.

Why? I'm in my mid 40s and have a 1 yo. I'd trade the adventure and hedonism of my 20s and 30s for good knees, a good back, quicker recovery from sleep deprivation, etc...

Now, don't just mate with anyone, be smart, look at how their parents are doing, ascertain their fundamental personality. IMHO 4-6 hours of real conversation is enough to tell if you want to spend the rest of your life with a person. The real challenge is listening to and believing that quiet little voice in your head. Which is a challenge because sometimes that takes 30+ years to learn how to do.

Aggressor nations have the privilege of lying to themselves on the consequences and reality of their wars. The defenders do not get the privilege to ignore that.

Americans barely talked about Afghanistan. For 20 years, our internet was full of funny videos, stupid songs, and memes of Osama bin Laden. Sure we bombed civilians targets and committed war crimes too, but we had very smart lawyers that taught us clever words for why it was moral when we did it. And we nodded our heads in agreement and turned the channel to American Idol.

Americans are well aware that technology enables us to live in our own artificially constructed reality. We spent the last 20 years building it.
