"So don’t forget to also buy a small portable solar panel. You can get them online for about $70."

The cost of the solar panel is mentioned but not the actual unit? Neither is the amount of water produced in a set amount of time.
Good product but weak article.

Looked at the abstract and found:
"The portable system desalinates brackish water and seawater (2.5–45 g/L) into drinkable water (defined by WHO guideline), with the energy consumptions of 0.4–4 (brackish water) and 15.6–26.6 W h/L (seawater), respectively."

Alcoholism is ABSOLUTELY more common in the US military than the general population. That’s in a culture that disapproves of alcoholism - if anything I’d expect it to be much higher than 37% in Russia

Not stupid, I also accidentally added something to the wrong container and it took me a while and some searching to find the answer. The feature is great, but the UX is still a little lacking.

Indeed. Stopping and reflecting on the perspective reveals it to be nonsensical.

Obviously if someone is toiling away in obscurity for 25 year stretches then they aren't going to be visible on Twitter. Most people aren't on Twitter, and the people who get airplay on Twitter tend not to be the thoughtful types.
GC isn't necessarily higher cost than not doing GC. garbage collectors are allowed to free objects when they want to which can be significantly faster than freeing in an arbitrary order as happens with manual memory management.
Automated small scale gardening ... Not sure if that exactly falls in this category.
OP, this is a good start. Everyone can do with criticism and introspection mixed with humor. Please continue making more. I’m sure Reddit would also be good source material for ideas.
It definitely is not a first generation star. It's only about 5 billion years old, while the universe is almost 14 billion years old.

Not only does earth have elements formed in older stars, so do all the planets in the solar system and our own sun.
Are they going to stay up-to-date with the latest version of Postgres? One problem with Yugabyte, TimescaleDB, Aurora etc. is that they are stuck on older versions of Postgres, which makes it feel like an entirely different product after a few years.

Why don't you search for jobs in the country you are living? It would be easier to find a job there than overseas.
Some examples:

MySQL and PostgreSQL in C++: learning curve is long, hard to write good quality code for newbies;

Presto in Java: GC of java is a "nightmare", hard to have subtle memory management;

TiDB in Go: similar challenges to Presto/java of memory management;

TiKV in Rust: seems a good one but Rust itself is not as popular as other languages. Plus, some drama occurred with Rust core team last year...
I've self-taught myself perhaps 1% of the knowledge in a music degree, and I enjoyed the video - even the parts I know I don't fully understand I can still appreciate.

I would go so far as to say most/all of the content posted on HN on a regular basis requires at least some advanced knowledge to fully understand. It doesn't seem to stop most people from enjoying it.
How does that work if I want something cheaper than a single family home such as a condo? I can't build a stand alone condo (I mean a stand alone 600 square foot house on a 0.05 acre lot would be awesome for me but zoning regulations prohibit that in practically all areas of the US). I'd need to organize dozens of people that also want a condo. That's not really feasible for me.

I'd also say zoning generally prohibits this in most desirable areas. Developers have the ability to do a lot of legal work to get approvals and permits. Since they are getting approval for a large number of buildings or units, they can distribute that cost and so they can sometimes build in those desirable areas where it would be too costly for me to build as an individual.
Right now, it should be possible to use anything that is compatible with the S3 API, as our current focus is on getting the product to the market. Once the business model is proven, we'll likely branch out to other clouds, with their storage providers.

Imagine not being able to understand the difference between quarantining a vessel and locking down an entire city.

Hint: one significant difference is that in the latter case it’s already too late.
So I don’t track this closely but I’m generally of the opinion (and do correct me) that NVIDIA’s anti-mining firmware tends to last ~1 day before someone turns it into a perfectly mining-suited card. So to the extent they’re breaking out crypto cards on the quarterly? Eh, I haven’t seen a 3090RTX on Amazon or at my Best Buy at MSRP a single time since it was released, though in fairness I sucked it up and bought the ones I needed at 3.5x MSRP some time ago, maybe it’s changed.

And as to mining on geo or PV or wind or whatever not being profitable? Wind blows at night, sun shines in Arizona, and geothermal is always on. I don’t think that it’s tough to get NVIDIA gear at retail because people are running a lot of Christmas lights. I think Ethermine is making a fucking mint, but like all such “no investors welcome” type ventures, I’m only speculating.
"Luck playing a part" is not the same as a false meritocracy.
The sun is estimated to have formed less than 5B years ago. The universe is roughly 13B and change years old, and the first stars started forming only 100M years after the beginning. There's absolutely no way it could be a first generation star.
Wow, it's the first time ever I see a confirmation that the weird approach I followed (mostly due to mistrust and weird teen ideas that the body might adapt) and worked on me has scientific bases and could work for others too and from an optometrist!

TYSM for speaking out!!!
I wish this were true in India, specifically, in tier 1 cities. They keep building high rises with lots of amenities while I’d like to live in a townhouse or a single family dwelling in an otherwise dense development. Indian families deserve split multi-level housing too but all we get as options are flats. Maddening.
A modern "AI" models have c. 200bn parameters, say. At 32bit/param that's c. 6TB. At 6 bytes/word, 1T words, or more words than are in all books that have ever been written.

NNs, and models of this kind, are just search engines. They store a compression of of everything ever written, and prediction is just googling through it.

Models performance exponential in parameter count should be just ignored by research. This category of performance is already established by research, more compute and more historical data stored, isnt an interesting research result.
The difficulty comes from the fact that VACUUM requires most of the same state that is required when processing a user transaction. For example, VACUUM needs the commit log to check whether a given transaction ID is for a transaction that committed or aborted (VACUUM also truncates the commit log to remove information about older XIDs when it is no longer required).

Aurora Postgres does still have VACUUM, which seems to work in the same way -- which is the same in Neon. AWS have in the past promoted Aurora as having significantly better performance characteristics when VACUUM is run. That may well be true, but the benefits seem to come from not having to generate full page writes in WAL, which are a way of preventing a low-level problem called torn pages. Theoretically you could just turn off full-page writes in standard Postgres if you had hardware that offered atomic page writes, though I don't think that it's a widespread practice.

I spend most of my time working on problems with VACUUM in Postgres itself (I'm one of the committers). An approach to organizing storage within transactional constraints seems necessary to push vacuuming down to storage, and that would more than likely need plenty of work in Postgres itself to be practical -- since it would cross a few layers of abstraction. Currently heapam doesn't specifically try to keep tuples inserted around the same time together, so it's hard to make anything that VACUUM does work implicitly or logically.

>Keeping existing infrastructure is causing the problems

Are we keeping existing infrastructure? Tell me if I'm wrong, because I am under the impression that several plants have been decommissioned over the past 5 years.
The sun is absolutely not a first generation star. It is approximately one third the current best estimated age of the universe (4.6B vs 13.8B years).
Another trade off with your approach of sending non-visible entities ahead of time is that it makes wall hacks possible.

Anyone aware of any conceptual way to “encrypt” the location data so it’s only usable if the player has line of sight? I doubt that’s easy/possible but don’t even know where to begin searching for research around topics like that.
The real issue here is scarcity of square footage. The US has more than enough land to house everyone.

According to Wikipedia:

* ~4 million mi^2 of land
* ~130 million housholds

This is about 19 acres per family. Of course this is an overestimate because a lot of land is waterways, mountains, etc. Even if we assume that we're off by 100x that's .2 acres/family which equates to a house something like this: https://www.zillow.com/homedetails/40-Canvasback-Ln-Elizabet...

Maybe instead of trying to put as many people as possible into as small of a square foot area we could:

1. Build public transit that can cover larger distances. (Street cars, busses, subways)

2. Artificially stimulate new communities (0 property & sales tax for any restaurants, bars, theaters, etc for 30 years)

3. Build out high quality infrastructure. This could be built underground with maintenance tunnels that allow these utilities to be repaired and could be subsidized by the construction of subways. (sewers, power, fiber)
The War on ‘Woke Capitalism’
I've had a fairly interesting journey through school. Changed schools too many times and at difficult times. I went to terrible schools (literally worst in the country), bad schools and good schools. I got lucky because I ended up in the good school for my last few years. I owe a lot to the wonderful teachers I had in those last couple of years. I benefitted also from tiny class sizes due to choosing the geeky stuff. Most of my classes were 100% male too.

My maths teacher was a young woman. Very attractive actually, but I didn't look at her in that way. Just effortlessly brilliant and made me love maths after finding it totally boring (too easy) through most of school.

My other teachers were really great and I think loved teaching the last couple of years with only the smart and determined kids left. I felt sorry for all the teachers before that who had to put up with the less smart ones. There's not much more satisfying than teaching smart people.
I remember those times too, completely different group of management, and the way they've done business in the last near decade, has also been very different. Some throwbacks, but on the whole, vastly different. I've been watching, you clearly haven't. And aside from that, they're never going to be in the "same position", the market is entirety different.
Is there any appetite for something at the federal level, or would this be seen as an unwelcome intervention for something that should be devolved to state level?

It's great that one city in Colorado has done something (and I'm sure it's not the only locality), but I can't help think that this sort of governance must lead to a ton of fragmentation in regulations.

Agreed on a lot of this, except that the 2000 blackouts gave us any clues about what to do for the blackouts decades later. Completer different, unrated causes. For 2000, deregulation was don't poorly and allowed a corrupt company to exploit a bad market. For the later blackouts, climate change estimates were not taken into account for extreme weather events, which led to underestimating peak load.

Air conditioning is going to hugely increase in popularity here in the UK. I think people like the tech, including better heating and sound and heat insulation and FTTP, but it's balanced out by the poor reputation of new builds in terms of quality issues.
Hence the "scary warnings". I don't think UI manipulation is stupid, I don't believe that Mozilla makes the best UI and extensions can definitely improve on it for many more specific use cases. Portability is also nice but not everything needs to be widely portable, I would rather have a nice feature in Firefox than not having it because it wasn't portable across browsers.

To be clear I am hugely in favour of WebExtensions. I am glad that they were implemented and I think that they should be the recommended API. But I would love to still have the full-power backdoor for the extensions that are no loner possible. For example I maintained VimFx for about a year after they stopped officially supporting these extensions and it was fine. The biggest pain wasn't actually keeping up with the internal API changes, it was the fact that it wasn't allowed in addons.mozilla.org anymore and there is no good way to distribute self-signed or third-part signed extensions.
It’s an easy assertion to make because even car transit itself is better in places that aren’t car centric. (Because fewer people are on the roads, and roads are much safer.)

It’s even worse in biology where some labs consistently publish in Nature, Science, Cell. Some of the papers are outright fraudulent. Don’t even trust the numbers.

At least for ML you can mostly reproduce the results, even in if they’re not that interesting.

> Talk to a fitness instructor.

I strongly agree out of personal experience. FIs have fixed all and every sedentary-job-induced ailment I've had so far. I highly recommend watching the athlean-x YT channel. Adding to that: also ask older, fit people you meet in the gym. They are full of good advice how to avoid injuries and, once you have one, getting over it.
They basically are. The various tract builders in the US (DR Horton, Lennnar, etc) even have the same offerings of budget and luxury models. You can get a Toyota which meets minimum code requirements (e.g. dr Horton express) or a Lexus (e.g. dr Horton emerald) which comes with nicer finishes.
The UK is well known for unaffordable, poor-quality housing. I'm not sure why you're holding it up as a good example.
> ..., whose utilities are deeply interwoven (can't run a systemd tool, say, resolved, without systemd)

The systemd components all depend on libsystemd (a systemd project), and the GNU apps all depend on glibc (a GNU project).

A common dependency doesn't make them all "deeply interwoven" in any meaningful way.
Let’s get in the full context:

>Nakano ward’s density of 21,956/km2, does rank a little closer to Manhattan (around 28,000/km2).

NYC is quite large. Huge areas of the Bronx, Brooklyn, Queens, and Staten Island have low-risers or single family homes.

Which if course brings the average down.

I don't think it follows that he feels sorry for himself. This bias in human thought could use correcting for several reasons. It runs a bit like the "just world" fallacy. On one side, you have things like the Republican party, where millions vote against their own interests on the basis of a delusion of control. Then you have the general lack of social safety nets in America, because of the just-world fallacy that people get what they deserve. Then, you have people like Jeff Bezos who credit themselves with deserving their wealth and lead companies with delivery drivers peeing in bottles not to get fired.

Most terminal users will find that weird, but among other weird things I tried it worked wonders for me!
A lot of HPC code is by its very nature pretty parallelizable (given that supercomputers these days are often just a large cluster of typical datacenter CPUs/GPUs with very fast interconnects), so is theoretically portable to GPUs for some gain.

The hangups mostly seem to be in that a lot of scientific code hasn't been written with GPU style parallelization in mind, so updating the code takes time. That said, since a lot of newer supercomputers are including a lot of GPUs, there is a lot more incentive for developers to attempt to port at least the parts that can benefit from GPUs.

From my (admittedly limited) experience, the biggest hangup is convincing scientists that GPUs aren't just another tech fad and it's worth the effort to port. There also seems to be a bit of uncertainty over which platform to trust, OpenCL support has been shaky on most vendors and is fairly primitive in terms of features, CUDA is tied to one company and AMD doesn't have a great record of supporting HIP across their product stack, so choosing any one is a big decision (comparable to choosing to use C/C++ or Python, which are effectively guaranteed to be supported on every supercomputer for the next decade or two).

GPU density is something you need to be careful with, the power draw is huge, so reducing it can have some upsides.
Headway is a great name for wayfinding! Looking forward to this evolving.
We already know that more compute hours give better results, and a paper which simply consists of rerunning previous work but with 100x the compute hours for .03% better results has not discovered anything new, and there's no point in reading that paper.
I probably used the wrong verb tense there.

We are not keeping the same infrastructure. But a proposal to keep it static would not meet our energy needs, because of extreme weather events. It also does not meet our needs for climate goals.

Thus the only way forward is lord more renewables and storage. We don't have any other options on the table.

Ask HN: Has anyone tried the Cavendish balance experiment with hydrogen liquid?
He used lead and others have used iron. Hydrogen is different as it has no (mostly no) neutrons. Has anyone tried to make a balance like his with hydrogen liquid? Neutrons are assumed to not act at a distance. But probably only because of the extreme difficulty of getting a neutron to stay still, long enough to measure it's attractiveness to other particles at a distance. One neutron can attract to more than one proton.
You can also add tags to bookmarks and let it search only through bookmarks.
