Another recent one, AlloyDB from Google Cloud. Looks pretty interesting/promising. Sort of like their competitor to AWS Aurora, built on top of Postgres, with the added ability to handle OLAP workloads well (along with apparently great OLTP performance).

TimescaleDB and Citus are notable too.

But yeah, if you’re building a DB product, starting with Postgres and customizing from there seems like an excellent approach.
> Pony does fearless concurrency better IMO

Pony is garbage collected. Most of the reasons why Rust async/await are the way it is boil down to the fact that Rust is memory safe without using GC.

> Forty2 shows how we can expand on Pony to be faster and more flexible

I can't tell from a glance, but that also looks garbage collected.

> For example, one can apply Loom's memory techniques to most memory management approaches to eliminate the coloring problem

Assuming you're referring to the JVM Project Loom, that's just M:N threading. This was tried in Rust almost a decade ago. Nobody used it because the performance was not appreciably better than 1:1 threading.

> There are also languages which separate threads' memory from each other which allows them to do non-atomic refcounting

You mean like Rust? Like, that's exactly why Rust can have both Rc and Arc and still be safe.

> relying on copying for any messages crossing thread boundaries (though that's often optimized away, and could be even less than Rust's clone()ing elsewhere).

Ancient Rust did this, but it was removed because with the current immutability and borrow checking rules there is no need for copying anymore. Why would you want copying if you don't need it?

I'm also not going to just accept that clone() could be faster. I mean, I'm sure the clone codegen could be improved by better register allocation or whatever, but I don't think that's what you mean.

> One could also apply that technique to a language using generational references, if they want something without RC or tracing GC.

Why would you want to copy if you don't have to?

> Sometimes I wish Rust waited just a few more years before going all-in on async/await. Alas!

I haven't seen anything here that is better than Rust's async/await, and a lot that's either worse or doesn't fit with the rest of Rust's design.

I certainly hope so, and I've since moved to a place that is much more friendly for cycling; however if you go back to where I'm from (which for the purposes of this topic really could be one of any untold hundreds of counties in the U.S.), there are no signs of improvement or change. It's just the largest urban cores that seem to slowly be getting it. There is a breathtakingly large amount of suburban sprawl where the conversation about this topic is completely broken, and for the people willing to admit there even is a problem, they believe that the solution is one more lane, or one more stop sign, or just educating drivers a little bit better and nobody wants to talk about things like traffic calming, or upzoning, or cycle paths or anything else that makes anything other than car trips safe and desirable.

A quick Google search indicates that $4B has been invested by VCs in video game companies since ~2010 [1]. The fact that these businesses are "hits based" actually aligns very closely with the power-law nature of VC returns.

I agree that cash is an important aspect of the economy that should be protected but I don't see how a couple coins that I have not heard of are going to be the panacea they purport to be.

For retirees, it depends. If they are in a target date fund, which most retirees are, the funds adjust their bond holding’s duration to minimize interest rate risk. The target date funds should have lowered the duration of the fixed income portfolio (ie from long dated to short dated) once they approach the target date.

The impact to short duration bond portfolios is not as drastic. A 2-year bond issued at .5% yield will lose maybe 5% in price when interest rate moves up to 3%. This is roughly what happened: https://fred.stlouisfed.org/series/DGS2
Rather than canned goods, prefer dry goods. In our basement we have 5-gallon buckets of lentils, chickpeas, millet, sunflower seeds, pepitas, and various other things. (Also cases of peanut butter, jarred tomatoes, various flours and such.) This isn't hoarding -- these are things we use! But we always make sure to reorder before a container runs out, which usually takes 6 months to a year.

When the pandemic hit, we just bought another 25 lb bag each of lentils and millet and called it good.
Commuting via public transportation from Santa Cruz to over the hill is simply not feasible. The 17 is a trap that used to cause way more deaths than any developed country would tolerate. It is difficult to believe how backwards some parts of the countries are.

One would expect that a very liberal town like SC would be strongly in favor of public transportation over the prison of cars, but it is the same old story: residents of SC are liberal when it means ignoring the homeless nightmare that are the downtown and lower ocean areas, but not when it is time to encourage and support public transportation or freeing the most beautiful coastal spots from the private properties of the rich.
Personally, I put very little stock in NYT health reporting articles. I am a public health researcher, and I have seen numerous NYT articles that just get fundamentals wrong. Though my field is not sleep studies, I can tell the conclusion of this article is essentially animal models[0] and longitudinal surveys[1] provide enough evidence to support hypothesis-driven studies in the future. But that's about it.

Now, that's not to say that chronic sleep debt isn't harmful. It probably is. But these kind of alarmist articles serve nothing more than to make waves in an already tumultuous field of popular science communication.

I know this comment boils down to "trust me", but I'm acutely tired and overall exhausted of media outlets that should know better churning out articles that are unsubstantial. I don't see these pieces as value neutral; they strain the relationship between scientists who study the nuance-filled physical world, statisticians who painstakingly analyze the counterintuitive world of numbers, and the general public who aren't equipped to (and shouldn't be expected to) understand the synthesis of entire fields of scientific literature.

Been monitoring my sleep the past few days and I find it weird that I always wake up after about 6 hours. On some days, I tried to go back to sleep to get that full 8 hours but I still don't feel fully energized throughout the day. Something that helps me maintain that energy though is a half hour nap in the middle of the day (or night since I work night shifts).
> How well could I survive eating local plants [...]?

I don't recommend this. As someone who has been foraging for over a decade, I believe you are much better off stockpiling food, learning to raise chickens, owning some fishing gear, maybe growing your own crops, and even learning to hunt small game.

Here's my educated opinion:

Foraging is fine as a sort of hobby or interest, but most people shouldn't consider it for survival and the vast majority of people have no business doing it at all. That might sound extreme, but trust me. I've witnessed so much stupidity in foraging communities, online and offline, that I completely gave up participating. Having to constantly correct bad and even dangerous advice got really tiring.

Being good at ID'ing and using plants requires adequate time spent gathering knowledge and experience. Most people won't come close because they don't have the interest.

Many people just don't have the visual processing skills. Foraging is a very visual skill. Some people have it. Foraging came natural to me because I'm highly visual. I can ID things very easily after an experience. Others I've known are nearly incapable of ID'ing plants reliably. I'd say at least half of people are not good at ID'ing and probably never will be without some app on a phone connected to the internet.

Foraging is and historically has been tertiary to hunting and agriculture/livestock. Most wild plants simply don't have the energy density to justify the energy spent to collect and eat them. Those that are energy dense are usually only around for a few months out of the year and still may not be that plentiful.

At best, foraging is a stopgap while crops are growing. I'd love to say that it's practical merely live off the land, and while I think I might be able to get away with it longer than the average person, it's just not viable for most.
Here's a good example of the problem. Marvel vs DC.

Both of these companies have significant (ie decades) of original material to draw upon. For the last 20 years, superhero movies have absolutely dominated the theaters.

But no one would look at this situation and draw any conclusion other than Marvel has trounced DC. Is the Marvel source material just that much better? IMHO it isn't to a significant enough degree.

What is different is execution. Marvel IP has just been better managed and they've had and built a better organization around it. It's drawn on Disney's extensive pedigree in this business.

Producing original content is difficult. It requires a culture of putting up with the 10 flops for that 1 breakout hit. There is no formula for that 1 breakout hit. A million factors go into why that hit became a hit and it's not a formula that can be copied and reproduced as the VC funding model demands.

Not a parent, but I was once that guy.

He might be depressed, so some therapy might be in order.

He's 18 year old, so he's an adult. Taking stuff he owns from him is not good. But the parents can take whatever they own from him, even the right to live at their parent's home.

So, the best course of action (in addition to explore some therapy for him) might be for the parents to negotiate with their son from a position of strength. If he doesn't like what is being suggested to him, he's free to get a place to live by himself. His home, his rules.

One of the best books on this topic is Why We Sleep by Matthew Walker. While I know people on HN dislike the author, I think it’s a great book to read once in your life and get the benefits of knowing how important sleep is without being too alarmist. It helped me each day to get better at sleeping. I think we pride ourselves on our hustle and lack of sleep where these badges hurt us both in the short term and long term. Perhaps that is just a season of life everyone goes through though.

From some recent HN discussions, a 2 minute headway for tracked transit seems to be the minimum based on both safe stopping distances and dwell time.

BART achieved 4 minute headways through the San Francisco subway portion. That also effectively limits headways on branch lines (absent additional trackage through SF) as when multiple 15m headway lines are combined the net headway is reduced.

For longer-haul commute service, 5--10 m headways aren't unreasonable, and a dedicated East-bayshore or Peninsula bayshore BART line might be able to accomplish this, with either a transfer or dedicated trackage in SF itself.

(Muni Metro runs on what was intended to be additional BART trackage.)

Quite frankly all this stuff is so far beyond petty to me these days I mostly just avoid it. Undoubtably travisbrown has been right a few times. Point is, I disagree with the premise entirely. As a society, we must tolerate some ugly hurtful trolls if it means we don’t harass the livelihood out of normal people with diverse points of view. Ethically for me it’s better to let a bothersome troll go unpunished than to unduly cancel genuine/harmless humans. If the Proud Boys are harassing drag events I’m sure there’s a way to deal with that involving law enforcement and civil court.
Note that getting a radio license requires publishing your legal name and a mailing (often home) address publicly in a government database under your callsign, and broadcasting your callsign with every transmission, effectively doxxing yourself to everyone within radio range. Additionally, some (generally older) ham radio users tend to exclude newcomers or are even racist (I once received a transmission without callsign (which is illegal) calling for killing n-words). In short, I do not consider getting or using a license to be safe for people in vulnerable situations.

The answer is: nobody knows, because nobody pays for anything with FileCoin. The services that get pointed to, like estuary, have the price of "free," and most of the incentives in the system are pumped in automatically to "reward suppliers" rather than there being any value transferred between people paying for storage and those providing storage.

Happy to adjust this conclusion - I've spent some hours trying to figure out how to pay for anything with FileCoin and come up empty-handed. Does anyone want to do a walkthrough of buying the coins, installing the software, storing data in exchange for FileCoin, and retrieving it?

In the meantime, you have to wonder: is this a sort of "you get what you pay for" scenario, and you pay nothing, so you get… no reliability?
