Deserts are about the worst imaginable place for solar panels. The only reason desert solar farms are constructed is that idiot investors think they are a good idea, and pour money into them.

Deserts are a dumb place for panels because the panels get hot and dusty. Heat cuts both conversion efficiency and panel lifetime. Accumulating dust can block as much as 80% of light.

The best place to site panels is floating on reservoirs and canals, where temperature is kept in check. Nobody knows how long floating panels could last. At the same time, they cut evaporative loss and biofouling, and provide complex habitat under for water creatures.

Next best is in farm fields, in rows with room for a tractor and equipment between. There, they cut heat stress and water loss, and run cooler than in desert or on rooftops. Most plants can use only a very limited amount of full sun in a day, and just endure more, welcoming shade. The panels produce year-round, complementing seasonal farm revenue.

A good way to deploy in fields is bifacial panels in vertical fence-rows running north-south to pick up morning and afternoon sun, during peak demand. Panels stay cooler, don't gather dust, and are out of the way of farm equipment; and fence mounts cost less than others. This works well in pasture, too, where livestock keep down weeds and benefit from shelter. (E.g., sheep produce better wool.)

For some crops, growing directly under (near-) horizontal panels protects them from harsh weather, often multiplying yield. A T-shaped mounting is practical here, with room under, and a gap between, for farm equipment.

Since the land is doing something else of value, there is no need to pack panels as tightly as they will go. There is way, way more viable dual-use farmland than could ever be needed for energy, so only the best places for it need be used.

Hydrocarbons are a poor choice of storage medium, because you need a source of carbon to make them, which is then released into the atmosphere when you burn it.

Hydrogen just needs water for feedstock. It is easily stored underground, including in used up fracking fields. It may be transported in liquified form, similar to LNG.

Ammonia needs just water and air as feedstock. It stores in liquid form under light pressure at room temperature, and transports well.

Hydrogen and ammonia are both massively valuable as feedstock for myriad industrial, transport, and agricultural processes, so when your tankage is full, all your excess production may be sold for ready cash.
Thanks! Turning the current language into a Turing complete one would be a huge step up in complexity and I'm not sure it will ever make sense to implement. But I have thought about adding the ability for users to define their own functions in JS and might get around to that one day.
> For the case of perovskite cells, adding layers does not seem to multiply the production cost.

I guess this makes sense given the hard bit is the substrate.

This would be good for everyone as second hand silicon cells for 10-30c/W will open up a bunch of new uses.
Q1: Yes, there is. Once a professional politician sees more activity from renters, they will include the renter's interests into their agenda

Q2: Yes, obviously there is a positive correlation. This is exactly why renters need to fight: stakes are against them. Current status quo is in favor of homeowners; it will not be possible to change it while being passive. Renters and homeowners have conflict of interests, there is inevitable fight.

Q3: I think blaming is the call for fight. If renters want better deal, they need to fight. Is it most constructive? I don't know, this is the best I can come up with. Does it reinforces the status quo? No, I think inactivity reinforces it.
Computing neural nets isnt something a CPU is optimized for (matrix calculations), This tech is based on gpu optmized LSTM's, acka Transformers, they can run on cuda, reducing time. GPU's perform those calculations fast for huge matrixes.
Doing it on a CPU (they're no good in fat matrix caclulations) it takes forever.
And yes.. essentially those neural nets are extreme huge matrixes with some predictive math in between.
Our economic system is set up such that you either hit a bar at which you accumulate capital forever unless you make a mistake, or you're loss-making forever.

Once you hit that bar, your job becomes buying up housing like it's a Monopoly board.

As an individual you can either choose to win or lose this game. We're not going to change it, at least not within our lifetimes.
> But households then need to rein in spending to repay their loans

Right now it looks like we may be about to witness something else: inflation is picking up, and if wages even just remotely track the increase in consumer prices (not assured ofc, but conceivable in a time of low unemployment), then those loans and their monthly instalments will actually make up a smaller proportion of household income (especially for those borrowers with fixed-rate loans).

What's the problem with FUSE?

Anyway, it needs a daemon on the remote system, but perhaps https://github.com/u-root/cpu is suitable. (I can't vouch for it, not having used it.)

The HTCondor batch system also provides something like that, but I don't know details, and it's probably not a separable component.

You can even call it "Monaco" if you come from Italy (because, same as the more commonly known Monaco, it was founded by monks), but Münich/Muenich is not a valid name for it in any language I am aware of...

I think this a problem in everywhere. Take for instance, Dhaka, the capital city of Bangladesh. Housing is a disaster. The home ownership percentage is so negligible it is a shame. Land and housing price is so high, it is almost impossible for most people to own a house in one life time. I hear the same kind of scenario in many other developing countries.

> They're violating Taiwan air space daily

They are not, actually, and I don't think they ever did.

> it could have tried to take other countries, like Poland, Moldova, some scandinavian countries

Of course not. Russia is not going to attack or invade NATO countries, nor is it clear why they would invade a non-NATO Scandinavian country... And in practical terms they couldn't really pulled off invading a country like Poland because they are not that strong beyond their nuclear arsenal, as Ukraine has made rather clear. There is a lot of scaremongering about Russia.

Korea was the closest to a world war and was more significant than Ukraine as the US and China actually came face to face but the US stopped it because they knew they could not invade China (which was the proposed next step) on top of not faring that well against Chinese troops in Korea.
Honestly, I agree. Scrolling experience is subpar on tmux (or a ssh session fwiw)
That does not solve the social issue that is at the core. A multi-billionaire won't care about the emission sequestration cost - it's simply impossible to spend down 20 billion dollars or more outside of donating all of it, which in any case only a handful of that caste does like Bill Gates, and even he has IIRC complained that it's hard to donate the money simply because it grows faster than it can be donated. Between his initial pledge in 2010 and now, despite billions of donations and a divorce, his net worth doubled [1].

If societies wish to avoid a revolution by the masses, the answer to luxury yachts and private jets must be bans and confiscations, not peanut payments. We've seen the potential for unrest with the French Yellow Vests - they started out as a protest against rising fuel prices due to a carbon tax [2], and the hike was a relatively harmless one compared to what will come should the true cost ever be reflected!

If you are really suggesting MySpace lost to Facebook because of the lack of newsfeed, you should do your research. FB introduced the feed—in the sense that we’re talking about, as a non-chronological selection of content by an algorithm that maximises ad revenue—only after MySpace was no longer a threat. That’s when FB could get away with it, since the critical mass has been achieved and users had nowhere to run anymore.

the fatal flaw in capitalism imo, a lot of wealth gets created which is good for everyone but eventually, a lot of that wealth also gets held by a smaller and smaller minority while the rest try to desperately compete over whatever is left over. After a certain point a certain portion of any new wealth created somehow trickles up to the capital owning class (think your VC's, fund owners, other rich investors), this capitalist system only works if "progress" happens in perpetuity, which if history is any indication society can always backslide

Ask HN: Has any Rust developer moved to embedded device programming?
Hi! Was wondering if any Rust developer have moved to embedded land. Did you switch to C/C++ or stayed with Rust? What MCU did you work with? Any tips?

I have good understanding of Rust and soon will need to program ESP32 chip. Write a driver and and http/tcp api on it.

Currently I jave seen mixed messages about Rust in embedded. Ecosystem moves fast, but semms like old C/C++ devs stay with their lang. So I'm curious what Rust devs have to say abou it.
Can you really meet them if they're scattered over a multi-million city? I find the opposite. A digestible size (< 500k?) city where everyone-knows-everyone opens more opportunities. While in megapolis multiple bubbles may be doing same thing, but not aware about each other at all.

But even here in just-over-500k city people are already resorting to Zoom calls from one's office/home (or lake-side getaways) over meeting in coffeeshop.
Most people think that there will be an omnipotent AI overlord that enslaves us, but that isn't very realistic.

Still, what happens is that analysts will slowly quantify almost every part of life. Your bank and insurances already score you. How the score is calculated isn't transparent. Your data is taken and the "intelligent" system puts out a number that allegedly quantifies risk, potential and other attributes. Slowly we will be enslaved by this as higher positions prefer delegating authority to a piece of software instead of others. More and more we will trust these artificial models until they almost completely influence our decisions. Statements without the "scientific" or formal confirmation of an "intelligent" system will be disregarded.

Actually I would prefer to defend myself against a sentient AI that just would want to kill us for the fun of it to a system that very much resembles a fortune teller from the middle ages.

Here is a side affect of having touch screens in new cars. As a blind person when my wife is driving I have to be very careful when changing the radio or music playing on Spotify as not to fuck things up or put her off driving. All so I cant change the AC in my half of the car. All so using my phone to play music is so laggy over blue tooth I cant use my screen reader to make things better. I all so have a friend who was born with one hand. He has to pull over if he wants to make changes to his radio or AC. In a car with nobs his stump can make most things work with out mutch of a struggle.
Undertaxation is rarely at the root of investment bubbles. Housing is the only one off the top of my head where I can envision a convincing argument for it being the chief reason.

FreeBSD is a modern performant OS with broad hardware support. I don't know what feature you had in mind, but FreeBSD comes with kqueue and has largely the same core utils as MacOS, which isn't a lot but why not take the free wins you can get? Not to mention that if they manage to pull this moonshot off, porting the resulting work to Linux would be utterly trivial in comparison. So ingrained Linux fanboys don't have to worry, if this becomes a thing, they'll get in on it.

This works through JNI. It will work fine as long as you don't use Java/Kotlin stuff. Then you will need to traverse back into the running VM. That has a serious overhead of going in/out of the VM. Since the Android UI is built in Java C code that tries to work with it is slower.

Notice that this isn't true for games which interact with the hardware directly in C. Only for high level UI stuff.

You can get a range multiplier even below that.

A car that uses 10kW average and has a 50km range is usable with a 7.5kW generator and stopping to charge every 200km. Knowing you have the ability to stop and charge or limp at 3/4ths speed to the next charger would allow more confidence pushing the boundaries.

A small battery means a 15 minute break to charge every 2 hours is viable and not a deal breaker for someone who only needs range infrequently.

Since we’re discussing preferences, drug sellers have a strong preference for people choosing crack over not crack.

Furthermore, their preference is the one that is consequential. Once you are addicted and chemically compelled to choose crack over what is more or less torture, the amount of agency you have is relatively insignificant.
One the the core issues with capitalism IMO is that it struggles to function as a meritocracy, because the reward for having merit - money - is itself an effective substitute for merit.

I've used many languages in my career, including Java, Scala, Ruby, and Node. I didn't really consider Java, for a couple of reasons.

- I don't love OOP. Go has just enough OOP patterns for me.

I tried Go as an experiment, but didn't know it would become my go-to language. What I found was super fast build times (big win), built in testing, and a simple language that almost anyone can understand (versus the relative sophistication of something like Scala).
