Same reason it's hard to do anything with solar. Grid scale storage is an unsolved problem.
I made a small arithmetic mistake at the end, 2.4MJ is about 0.66kWh

But otherwise it's correct, we're at about 20% of the theoretical maximum. The best RO systems are right now working towards 2kWh per cubic meter: https://uh.edu/uh-energy/educational-programs/tieep/content/...
A sensible thing to do is to turn the waste brine water into a resource. Since it's already been pumped up, pour it out into an evaporation pond to increase humidity in an area that could benefit from it, and then scoop up the salt to extract valuable minerals.
Has anyone built a mobile app on top of SQLite that can work offline, but then sync to a server when it gets connectivity? It feels like this could be built with a similar approach to this distributed SQLite, you'd "just" need more robust conflict handling.
Prepare to be amazed and watch "Copper" by Surprise!Productions (1992) [1].
It has hardware zooming, vertical and horizontal copper bars, and even a horizontal wobble all on a regular VGA card (although not many cards or emulators support it)!

One interesting VGA hardware effect in this context which I have not seen in any demo, is to change the character width from 8 to 9 pixels _during_ a horizontal scanline. The trick is to use RDTSC to estimate the pixel position, with which you can create a nice wobble effect in text mode. Obviously, this requires a Pentium or higher, and at the time this became possible, text mode was rather outdated.

I tried to switch my nodejs project to deno and discovered it “just doesn’t work that way”.

Deno is not a drop in replacement for nodejs, which is a pity.
> The summary contains information that was present in the original but it has been transformed and hence it's not a copy.

The summary also contains original thought, something is added to it by a human to make it unique. AI models are primarily deriviative.

A better example would be: if I take 1,000 different copyrighted works and put them into a ZIP file, does that resulting file violate copyright?

Why is that?

There's some confusion here that needs to be dispelled.

First, there's two categories of add-ons:

- add-ons that get audited by Mozilla
- add-ons that do not

The ones they audit enjoy Mozillas endorsement in the app store, and an exemption from the quarantined sites setting.

The quarantined sites setting only differentiates between the two categories. The audited apps are known to be non malicious, so they are exempt from the quarantined sites setting. The other add-ons are unknowns, and this sets a default access level.

The ability to granularly opt extensions in/out is being worked on, and will likely ship with 116, per the comment I linked:

It'd be lovely to see a government experiment with an issue based information system someday. Agree to move beyond open debate, & compel representatives to explicitly structure out issues, positions, & arguments for topics they discuss.

https://en.wikipedia.org/wiki/Issue-based_information_system

Just being able to capture what the different elements of policy debate really are would let so much more nuance be retained. And when going back to assess the impacts of a policy, there'd be such a clearer record of argumentation to assess: what did happen, what didn't happen, who was right here?
Has it been successful? NetBSD seems to be more popular.
Last time I used freeBSD was as a child circa 18 years ago.
a lot of what you describe in terms of work culture, expectations, stress, grinder, test of willpower and discipline... is pretty much how high achieving students who suicide describe their lives. So, it's not fortitude, it's other supportive elements of one's emotional life that get one through it.
> It was a mainframe operating system that only ran on high-end hardware. What do you expect?

I expect that by 1975, say, the number of high-end hardware installations was a lot more than 80. Multics, even when completed, didn't make much of a dent in the world. The ideas were influential, used in a number of later OSes, but Multics itself didn't go very far.

> Yes. It was also less capable. Both of those things were design goals of Unix and not of Multics.

Yes. Multics had the wrong design goals. Arguably, it hit them, but that didn't matter, because they were the wrong goals (though not obviously wrong at the time). That's why Multics is given short shrift - it successfully implemented what turned out in retrospect to be the wrong thing.

Why were they the wrong goals? There were something like 600,000 PDP-11s sold. Sure, Unix didn't go on all of those, and Multics could have run on more than the 80 machines that it did. Still, that's an insanely large number of installations that they... not exactly ignored, because even the first PDP-11 hadn't shipped when the Multics project began, but at least a huge number of machines that they were unable to serve. And of course, as always happens in this business, the lower-end machines became more and more powerful. The result of that (plus easier portability) was that Unix ate the world, and Multics became a footnote.
Yes, but you pay for that when you purchase the products. These costs are baked in.

The Overflowing Brain: Information overload and the limits of working memory
A programmer's confidence can come from a few different directions.

The chief one, I think, comes from simply having achieved enough challenging problems to the point where one knows that, even if their solution isn't perfect, they can figure out basically anything. The overwhelming majority of programmers can get to this point eventually.

Confidence also comes from the eventual realization that, with few exceptions, the majority of programmers you think are "better" than you are really aren't objectively better. They may have a fancier title, a bunch of GitHub stars, have given presentations, or maybe they've written a book, but this doesn't mean they are a better programmer than you. It might be hard to understand as a novice, because virtually every novice is going to feel inferior for lack of experience. After having gained sufficient experience, to the point where there's seemingly no problem one can't solve, it may become obvious that these programmers one once viewed as elites actually just broadcast their craft in a way that gives them higher authority; I stopped viewing most programmers as being better or worse than each other because I've witnessed enough problems caused by the clever solutions of senior and staff developers. It's just much easier to blame a junior engineer's solution when it doesn't work out. This isn't to say that more seasoned programmers aren't worth their salt, but there's almost never something they have that you can't have, and every programmer out there writes bugs all the time!

And finally, seeing the tech hype come and go over a long enough period of time can eventually bring one to the point where they look back on methodologies, frameworks, and design patterns they were once introduced to and come up with the original thought of "You know, I think that X was kinda bullshit to begin with." I think it's really unlikely that a programmer can have a 20+ year career (or even a 10+ one for that matter) and not come to some conclusions like that. Though it's easy for a novice to get caught up in the churn thinking they've got to learn all the things and feel inferior for not knowing it all, experience may someday teach the programmer that most of the churn was hype and that their own ideas on how to program effectively probably would have worked just fine.

I would say that I gained my confidence by just trying enough times and gaining experience.
A bug bounty would possibly have a bigger payout lol

Sounds like a fun place to be in an earthquake.
Funnily enough, getting bugged by some random people about a bug in one of my projects. I'd built projects before, mostly for the fun of making them, and occasionally for my own use. The first time someone reached out to me on Discord going "Hey, love your tool, but this feature hangs my machine" was a wake-up call that I had actually succeeded in making something useful.
Wrt TKL (and smaller) vs full-size keyboards; you can easily also get separate numpads these days. You might wonder what is the point of getting tkl keyboard and then separate numpad, the answer being that you can then position it more ergonomically, for example on left side of keyboard or right side of mouse.
I agree. I did not expect .NET to do so well.

Another surprise is perhaps the quadratic benchmark[1]. Even for automata oriented engines, it provokes a case that is unavoidably O(m * n^2). Basically, the automata oriented engines (rust/regex, go/regexp and re2) all have worst case O(m * n) time complexity for an individual search. But when you move to "iterate over all matches in a haystack," that worst case gets bumped up to O(m * n^2) for certain classes of regexes.

All regex engines in the barometer, except for Hyperscan, suffer from this problem. That's not because of any special secret in Hyperscan, but rather, that it implements different match semantics than every other engine.

I'm otherwise finding it hard to say what is "surprising" haha. Perhaps others from the outside can comment.

If you're talking about the US, then I believe it's actually a strong minority that generally hamstrings the government and occasionally rules using non-democratic methods as needed.
The cost of office space for Twitter is negligible compared to their other costs. 1500 employees could fit in a handful of low-rise office buildings.

In any case, Musk can be pro-RTO for the same reason numerous other CEOs are: they have significant sums invested in commercial real estate, and don't want prices to enter a downward spiral.
Back in the days of Battle.Net and Warcraft III, I used to sit on my friend's computer playing 1:1 games. I played different races a lot and sort of got good, but I was bored.

So I decided that I would exclusively play Night Elf and build nothing but Protector Trees.

Now Protector Trees are Night Elf "buildings" which are, of course, rooted in the ground but they can throw boulders at attacking units, thus defending the home base. Protectors also have the unique ability to uproot themselves and move around the board, then take root somewhere else. I believe they are not capable of hurling boulders whilst uprooted.

So that's what I would do: I'd build a bunch of Protectors (and enough Wisps to repair them all) and then I'd uproot a "formidable" Protector army and march to the enemy base.

This was mostly ineffective and readily defeated by a capable adversary, but I really trololoved the reactions some of them had. They would be absolutely flabbergasted that I'd wasted my time on something so dumb. But it was undeniably hilarious from my perspective to just watch a bunch of trees waltz into the enemy's home base and start hurling boulders at everything in sight.
Important to pay attention to the content of the alarm though. Altman went in front of congress and a Senator said “when you say things could go badly, I assume you are talking about jobs”. Many people are alarmed about disinformation, job destruction, bias, etc.

Actually holding an x-risk belief is still a fringe position, most people still laugh it off.

That said, the Overton Window is moving. The Time piece from Yudkowsky was something of a milestone (even if it was widely ridiculed).
If you choose to pay him, sure.

None of what you wrote here leads to the advice that one should, as a matter of regular course, hide from or disengage in understanding what is going on around them, however.
I can tell you what limited my confidence as a programmer. It was correctness, or knowing how to deal with stuff so I don't have to check every line of code once I implemented something new that uses the old stuff in a novel way. For some people, it was apparent right away, but I had to discover that once you design something that works in all cases, you don't have to check wether it works as a part of newer code flow, or bigger use case. Only then my confidence started to compound.

In the late 90s to early 2010s it was fashionable to think of code as a graph of dependencies, and as long as you honor those dependencies when changing the code you would be ok. This is simplifying but pernicious POV IMO - reinforced by the zeitgeist that code is truth and comments (in code or otherwise) may not be. This is a cul-de-sac.

Unless developers see things as nouns or verbs, they don't acquire the ability to scale and see the bigger picture, because there is nothing to hold these smaller entities and connections between them (O(entities^2)). The concepts are the bags. Wish someone would explicitly teach us these things, because, sure as hell they didn't teach it in college.

May be people who have a liberal arts background are good at seeing these things, because one of the things they explicitly study is perspective, framing etc. Engineering is quite limited because we don't explicitly study about that.

One of desalination facilities I think is actually solar powered. It mix of evaporative desalination with power generation (giant tower that a bunch of mirrors focus light one). Not sure if it's in production now.

But in general in Israel solar has a couple of problems: very dusty (sand storms) and local electrical company which tends to create problems
> Can there be such a thing as "non-partisan state-sponsored media"?

You can add enough layers of indirection and semi-elected committees and cultural expectations to make it mostly non-partisan (Think the process for awarding government-funded research grants)[1], but a government devoted to turning it into a partisan organ can, with enough effort, eventually corrupt any such system.

That's why you need to push back, and punish governments that are trying to shift cultural expectations that prevent weaponization of various public institutions.

[1] The incentives for corrupting this are far greater for media than they are for science, so I can't expect it will work well in practice. PBS, NPR, CBC, BBC are always a political football for this reason.

> The Apple Vision Pro has VR and AR capabilities. When you view a representation of your monitor it's VR. When your monitor is represented as an object in physical space then it's AR. Apple Vision Pro can do both, but my point is I don't understand the value in the latter, at least at the price point

Safety is a big reason to prefer AR for "big monitors" in HMD, especially in any home with furniture (much less clutter) or children or pets. Apple's argument so far seems to be that to get that sort of AR right in an HMD form factor much of the price is necessary (they pack in a lot of cameras to do it right) and the high price may not be an accident, it may be a requirement for good AR (at least in an HMD with current tech).

Then I did a poor job of explaining my point.

A thesis in the linked-to piece is that certain types of construction don't exist in the US, so people don't know the options even exist. This guides their understanding of what is appropriate. It points out how these design differences are part of a large interwoven set of ideas which extends to how American cities are designed.

wunderland followed up on that latter point. I agree with the general thesis, but I think wunderland stated it rudely and disdainfully. I think wunderland also fell into the trap of contrasting "low-density" housing with "high-density", which makes people think of Manhattan skyscrapers, when there are plenty of sorts of medium-density housing that gets what wunderland wants. (I can provide examples if you wish.)

In my comment I wanted to highlight that yes, certainly there are many Americans who like "low-density sprawls where everyone has a useless yard" and (correctly!) reject that characterization. Which I think is fine - it's not like Europeans don't have have single-family homes.

But there are plenty of other people who do want alternatives, like walkable neighborhoods. These people have many of the same goals - a safe place for kids, somewhere to garden, outdoor semi-private area for entertaining friends, etc. - but don't want what they regard as the clear negatives of living in single-family detached housing. I listed a couple to be clear: yard maintenance, and required chauffeur service for the kids.

I've talked to people at that housing co-op in California. They got the idea from Danish housing practices. Making it fit into California housing law was tricky, because unlike in Denmark, the CA laws weren't designed with that in mind. Yet while the people I met there really enjoyed it, I know it's not for everyone. Just like how there are people in Denmark who live in single-family detached houses.

Or, I've read stories of people in the US who want to set up a part of town with restricted car traffic (something like Barcelona's car-free superblocks), only to face massive protests from people who want to be able to drive everywhere, and see this as a restriction on their freedom.

Not realizing, perhaps, that car-traffic roads restrict the freedom of others, like the freedom for children to play on the streets in front of their home. But we've been sold the myth that "streets are (only) for cars", making it hard to remember that that's not the only thing they are used for.

The goal isn't "there should be no cars anywhere" but that "there should some places with cars and some places without."

As wunderbar quoted from the article: "From building codes to systems of labor and construction, everything is designed with the detached single-family home in mind: zoning that bans apartments (and density and affordability) over large swaths of urban America."

It's hard to see what isn't there. Don't let your enjoyment of your current situation make you blind to how others may want alternatives.
For open ai specifically I think they genuinely do believe in their own brand of pronoun-adjacent-hedonism style of liberalism.
Many years ago I worked at a startup doing this - putting cameras on tower cranes. Fun times. Took a while to find PMF and the startup ended up going under. Good times, was super fun!
My take is that its true that there is some limitation imposed by the data ingested but it's not exactly a hard limit. If you think of intelligence as compression, yes compression does have physical limits, but there are multiple dimensions of intelligence.

For example, leading-edge AI could create new layers of information that are more abstract than previously created. The ability to effectively and efficiently manipulate this creates something that could be referred to as higher intelligence.

The big thing that people are failing to anticipate though is hyperspeed intelligence. AI will be able to reason dozens of times faster than humans in the near future. And likely at a fairly genius (although perhaps not totally in-human) level. This effectively is superintelligence.

The reason this is more anticipatory rather than speculative is because LLMs are a very specific application that now have a huge amount of effort going into efficiency improvements. They can be improved in terms of the software stack running the models, the models themselves, and the hardware. And sometimes all of the above.

The history of computing shows exponential improvements in hardware efficiency. Especially in the context of this specific application, it is unlikely that we will see a total break from history.

So we should anticipate the IQ getting at least somewhat higher and the output speed increasing by likely more than one order of magnitude within the next decade.
No, fresh water just enters the water cycle. It will eventually evaporate or end up in a river and back into the ocean where it will be reunited with the salt. The overall salt concentration of the ocean would not be changed unless we sequestered the fresh water permanently. Even then it would take a tremendous effort to make even the tiniest difference in salinity.
