Yes. It's all well and good having gigabit+ connections, but latency is the killer.

Here in Perth, Western Australia we are very far from everything. In the 90s/early 2000's our routing and latency was pretty terrible, especially over dialup and slow connections and that's how I thought online gaming was (300ms+++).

When there started to be "local" servers in Adelaide (thanks Internode!) and Sydney, this went down to 25-30ms for adelaide and 50ms for Sydney.

Now we have undersea cables to Singapore from Perth, so we actually get 2ms lower latency from PER->SNG than PER->SYD! Sometimes I get weird routing through Asia if a service determines I'm better suited for that. There is apparently also a cable from PER->Europe now, where we now get less latency to EU (it's now less than US, crazy).

Those second two hydro stations came online at roughly the same time as nuclear plants quite close to them. Seems odd that so much hydro came online near nuclear power plants at roughly the same time if it's there to support fossil fuels.

Renewables are on the order of 100GW net per year. This is projected to double or quadruple by 2030. Where does the millions of tonnes of Natural Uranium to start terawatts of reactors come from?

If you want to bring down costs via serial production you need to start now and it will take you 20 years.

The current capacity of lithium battery production operating or opening next year is around 1TWh/yr. If 50GW of reactors was brought online per year it would require doubling current Uranium mining and enriching facilities to provide the first load for each.

The _current_ world battery production can provide 10-20hrs of storage each year for 50GW of new renewables (most analyses show you can replace most of your energy with about 4hr storage if you keep the gas turbines for emergencies). 100s of GWh of new production are coming online each year with new chemistries scaling up to ease strain on lithium extraction.

Looks like Nuclear power can at best match current renewable and storage production. By all means build as many PWRs as you can as a small suppliment to the renewable production, but the nuclear industry just does not have anywhere near the scale needed and we can't afford to wait for the industry to figure out MSRs and then build them in serial.
Carbon-Capture Projects Are Taking Off. Here’s How They Work

Safari has already shipped AVIF support with iOS 16 and macOS Ventura.

Apple is a member of AoM backing AV1/AVIF formats, together with other browser vendors.
Beautifully written article -- I couldn't agree more. From my personal point of view the biggest impact are:

1) e-commerce textures such as cloths are more faitfully represented -- more trust in e-commerce, more revenue

2) more equity for selfies, people-of-color skin is better represented in JPEG XL, selfies in general look more people like with less smoothing of skin performed at compression stage -- I'm a great friend of the idea that filtering should not be built into the compression so that all kinds of images can be transmitted

3) more compression, faster and cheaper to load

4) better progression -- unlike I believe AVIF does, JPEG XL progression does not impose more decoding cost for sequential, progression does not make compression density worse

5) thermal camera support -- I believe thermal cameras have huge ecological and cost optimization opportunities and more phones should have thermal cameras in them to facilitate the shift away from fossil fuels

6) small images -- thumbnails and sprites etc. do not necessarily need spriting with JPEG XL. That is a nice increase in system level simplicity. JPEG XL overhead is about 10-20 bytes whereas AVIF overhead seems to be 600 bytes or so.

7) 'it just works, no surprises' -- the worst case image quality degradation in any quality setting are much less severe and much less common than in other formats
Asteroid mining is another very profitable and useful option. We are talking about many trillions to be made, many things to be built, and people who get up there first could end up controlling lots of things for the foreseeable centuries.

Think of British East India Company, except the scope is way more than anything we can imagine.

If you are a super power, a project like this is something you must absolutely consider.
This is written in C. I wonder how common it is to write PG extensions in safer langugaes and what would be the most suitable.

I'm somewhat wary of using nontrivial C extensions, having seen so many of them sometimes seg fault the backend (eg PostGIS). There seem to be PG backend crashes described in this projects issues as well.

I find it funny that this is the only answer from someone affected, and it doesn't even attempt to explain what is wrong with the name, even as a snark.
The funny thing about AVIF support in Chrome is that, unlike JPEG XL, there was no experimental period. It was enabled by default from the beginning (in Chrome 85).
Is this actually the case or are you just judging the tool based on your assumption?
Technically yes, but in reality, greed... greed never changes. And immigration regulations that are intended to protect against abuse of the system, are often abused to extort people.

E.g., you're from country X, living in a new country, Y, where you've bought a small business. Y is a desirable country to live in if you are from X. Your business is very low margin. You work very long hours to keep afloat.

But, an immigration broker also from country X gets in touch. They have many clients back home who would love to be in country Y. They just need a work visa, but the job has to be a) skilled and b) not able to be easily filled by an existing citizen or permanent resident of Y.

So here's the deal. The client pays the broker to be introduce to you. The client then agrees to pay you for a job - often there's a lump sum up-front, and often there's ongoing payments made under the table to the employer. You have to create a position that's suitably skilled of course, and you have to prove you couldn't fill the role locally.

So your corner store is now recruiting for a "retail and marketing manager", and you placed one advert in the situations vacant in a local newspaper, no-one replied. You are now able to recruit your retail and marketing manager from X, and they can move here knowing that they have a work visa.

It's a great deal - your worker got to move from X to Y, and you got an employee who, after their below-table payments to you, is likely working for far below minimum wage.

And here's the best bit - if you treat them like crap, and they decide to complain to the authorities, well, given that they knowingly participated in immigration fraud, which you have proof of, they're very likely to be deported and banned from returning. So they have a very strong disincentive to complain, no matter how you treat them. And thus you continue to have a good source of revenue and cheap labour until they've been in the country long enough to apply for residence.

And then, gosh well, you'll need another retail and marketing manager, won't you? Who pays a lump-sum upfront, and then kickbacks for two years.

Here's some examples from my country:

https://www.rnz.co.nz/news/national/411939/samoan-chief-jose...

https://www.stuff.co.nz/business/123020969/tauranga-man-char...

Fixing this is a hard question - yes, we want workers being exploited to be able to complain, but we also don't want people lying and falsifying documentation to get a visa. So what do you do in these scenarios? Where do you find a balance?

How does that invalid my points of China's companies and US companies are not at the same level? Yeah America bad it's not that effective I totally agree with you. Let me rephrase it this way, if you think Google/Meta (which I agree), China companies are much worse. Democratic countries have many problems. But please stop comparing them to the countries like China. There are levels.
As mentioned above, Safari 16 is shipping with AVIF support so Edge is the last holdout.

I hope you realize that black people are wondering the same thing about you and how unfair it is to black people.

I doubt white people are surprised by other white people can be racist. It is part of mainstream media. What may surprise you is many black people can be racist against other black people too.
We wrote WebP in C -- in the creative phase of codec and format development I kept it in C++, the feasibility proto was initially launched in C++ (perhaps 0.2 version of the lossless coding, late 2011), but I ported it to C a few months after that and handed it over to the WebP production team (early 2012) who kept making improvements like streaming decoding

Not just employee gifts, but nearly all gifts are valued less by the receiver than the giver.

A gift represents a decision made on behalf of the receiver by the giver. In very few situations would the receiver make the same decision as the giver with the same resources. It's assumed that the receiver will use the same resources in an optimal manner, so gift-giving is a net negative.

In some circumstances, gifts are valued higher by the receiver than the giver. Gifts of time, of expertise, of opportunity, or things that the giver can get at a much lower cost than the receiver - these can be more appreciated.

Anyway, that's my grand theory of gifting, and why I generally avoid it, unless I can make it worthwhile to the gift receiver.

Mozilla is one of the founding members of AoM backing AVIF/AV1. They're shipping AVIF support enlabled.

The JPEG-XL bug hasn't received any news or updates for at least a year now and the support is disabled on all stable builds (meaning: you can't even enable it with a flag since it's not compiled in). You can enable a flag on nightlies.
As weird as it sounds, it is still the best.

If we have centralised "licensing" solution it is abused by large capital to wash off smaller - there is plenty of examples.

If we have decentralised solution (which is basically what review is) - it is immediately abused by "marketers".

There is no simple and easy solution to the problem.
Well written and kind response. Thank you for doing this. We could use a bit more of this on HN.
True. I haven't heard a Tesla's catalytic converter got stolen yet.

> Water consumption with respect to the animals themselves is high but once you factor in all of the water used in the production of the feed itself it's crazy especially when considering the subsidies in play.

Animals are properly used to upcycle calories which humans can’t consume. Ideally the heavy lifting would be done by bugs, egg chickens and dairy cows.

Subsidies were initiated by politicians who didn’t understand the problem they were trying to solve.
It's the other way around, obviously.

Not a single one of your links relates to a privacy "violation" though. Once again, I'm asking someone to tell me what they take that Google and Meta don't.
Just the other day I was wondering why execve is a syscall in the first place, feels like lot of what its doing under the hood would really belong to userspace as it doesn't require special priveleges.
I do this through calendar notifications but I agree that there isn't as much granularity, such as "ping me X times a week but once I finish a task, stop pinging me." Calendars don't keep track of that kind of state and thus aren't well suited to this kind of productivity tracking.

I'm building something in the same space [0], the landing page is outdated but the version in my head is similar to your idea, as a mobile app in Flutter with a Rust backend API, and Twilio for the SMS, calling, and emailing.

And good for you for cutting scope and just launching! That's what I did a few weeks ago, I built a site in 24 hours, launched it on HN and Reddit, and got 20k visitors in a 48 hour span after launching [1] because I was tired of procrastinating launching products. I also got a lot of really good feedback from the launches, so now I'm learning that launching early and often is key to iterative development.

Don't worry about the pricing by the way. I'm going to make my app cost $20 a month simply to weed out people who won't take habit formation seriously. Those that want to buy it will buy it and those that won't, well, they're not really worth caring about since they're not your customers anyway.

Ford bet big on palladium in the 90s, so any Ford cat from an engine introduced before ~2002 is likely to have a relatively large amount of palladium in it. Some of their larger trucks have nearly 1/2 an oz, which was worth about $40 in 1992 and nearly $700 today (there was a palladium shortage during COVID and palladium briefly was over $3k/oz).

My Ford was federally licensed rather than CARB, so I'm required to replace it with an OEM converter. There is no ETA on when one will be available.
To be fair, I think the commentor was being sarcastic.

It's also the dumbest, worst kind of meth: the kind you make in a 2-liter bottle using camping gas as a solvent, carefully burping it every 5 minutes so the ammonia gas buildup doesn't rupture the bottle. It could be rational to regulate Sudafed even if lab meth was widely available on the street; the lab meth isn't setting huge building fires.
I don't think you are seeing the historical context. Race is very much a part of it. America had to overcome slavery, redlining, Jim Crow, etc... These were based on race, not economic position. Affirmative action is an attempt to rectify the long standing American issues of discrimination based on race and other attributes (sex, color, etc...).

Economic position or being at an economic disadvantage is a different argument than what you had originally presented and the attack on affirmative action. America did not develop as, and still is not, a society blind to race, color, or sex. Better that you had made that argument, which would possibly be along the lines of better loans, scholarships, free education, etc...
This is so amazing, thank you!

That might with with C, but won't work with e.g. Python.
Postgres itself is written in C. I suppose its every internal interface is in C. I wonder how many unsafe sections would an extension written in Rust have to have to use these interfaces.

I wish something like Lua + LuaJIT could be used to write such extensions; at least it's memory-safe. OTOH mapping these C interfaces to Lua structures, and making them work with GC may happen to be non-trivial.
Well, we are talking about functional programming improving program correctness. Such behavior doesn't help. Better choose another language that is a fit for it.

> The Fed has been funding extremely reckless fiscal policy for two years. We literally shut the economy down and gave people checks for doing nothing. I don't think we need to reach for fancy explanations. The reason for inflation seems plainly obvious to me.

100% this. I don't understand the motivation or the logic of the people who argue against something that's so obvious
So, if the Fed has made a terrible mistake and the theory is disproven , will it have to be abolished / change mandate?
If my customers are racist and I know they'd balk at working with people of a particular race, am I justified in refusing to hire employees of said race? After all I'm just giving customers what they need to get service.

No, not at all. In fact, this rationale was a trope for racist practices around the world. Japanese bath houses would refuse service to foreigners claiming doing so would drive away japanese customers. White employers in the US would refuse to hire Black staff reasoning that customers wouldn't respect them. I read Ben Carson's memoir (I do not endorse his views, as a disclaimer) and in it he details an episode where a white patient refused to be treated by a black physician. His boss told the patient that she'd get the same excellent quality of care that she'd get from any other physician and wouldn't supply an alternative to Carson. As a Latin person, I'd feel perfectly comfortable with a Latin person refusing service from a Black, Asian, white, Jewish, or doctor what whatever category you pick.

Also, as a member of a "marginalized" group I can say the Economist is spot on with the fact that class far more salient in real life than ethnic difference. There's plenty of Latin people that fit the image of a disadvantaged Latin immigrant, struggling to make ends meet. Certainly a greater proportion than whites, but there's plenty of us that aren't underprivileged compared to your average white person. The distinction between a poor Latin immigrant and an American born Latin tech worker like me is far, far greater than the difference between me and the average white tech worker and the poor Latin immigrant with, say, a poor Ukrainian refugee.

I'm a "software systems engineer." I write a lot of code for various projects (I'm good at it), operate a spacecraft, do some sysadmining, and am leading a citizen science project. I'm not really sure what my title means. Sometimes I write software specs or list requirements. I've read a few definitions of SSE but as far as I can tell, it's not a well-defined discipline like mechanical engineering, philosophy, music theory, or geochemistry (my PhD). Shrug. I guess it's reassuring to see that lots of people have questions about what systems engineering is supposed to be exactly... I was worried I was missing something.
This title gave me MSN vibes. Anyone remember the unlimited nudges hack?
Many good points.

> There is a huge difference between the Admission rates for Asians Vs African Americans. In fact the admission rate for Asians is lower than Whites!

You seem to assume that the applicant pool is equally strong across races, especially with reference to the parts of the application outside of test scores and grades. I humbly suggest that this is not true.

> It does not matter that the current percentage is 27% when Harvard itself admitted that it would be 40% if not for AA.

I would like to see that exact quote. Iirc, that was the stat if they went by grades and test scores, which they never have and most likely never will.

> And finally I do not understand where this degree of faith in Harvard is coming from?

I have worked in an advisory capacity at several elite schools on the admissions process.

I’ve seen how the sausage is made. Most people get it incredibly wrong.

> This is the institution that systematically gave Asian significantly lower "personality scores" without even meeting them. Even while their own alumni rated Asians similar to their peers. Is this not an explicitly exclusionary policy?

Maybe.

The real question is if they also rated non-Asian people with similar profiles low on the personality score.

Let me tell you, there are an absurd number of applicants to elite schools that are basically doppelgängers. Strong grades, strong SAT scores, similar essays to thousands of other applicants, no outstanding hook, “standard strong” recommendations, etc. There is nothing that makes these applicants stand out to the reviewer. They may be super pleasant to be around and highly articulate, but so what? So are truckloads of other applicants.

I haven’t seen the comparable numbers for Asians versus other races, but there are no shortage of boring white applicants and boring applicants from every race that would warrant a lower personality score (however that is described).

Additionally, there are a number of reasons that one group or race might have lower average personality scores than another group that don’t involve racism. As a simple made up example, the ratio of “hail Mary” applications to strong applications might impact this. Note that I have no idea what race/group sends a higher percentage of Hail Mary apps than another, but it wouldn’t surprise me if there were a few.

I can tell you one group that definitely exists. Kids of upper middle class parents in the northeast corridor who are pushing their kids to an elite school when their kid absolutely doesn’t care. The vast majority of these applicants probably have low personality ratings because they aren’t really trying that hard to stand out. Is that exclusionary? I dunno… seems reasonable to me.
>That's gaming the system, for personal benefits, and contrary to the purposes for which affirmative action was created

It should have been abundantly clear to anyone that I mentioned CollegeVine to show how the system works, not that we intend to apply as another race. Sheesh.
PG ships with Lua support: https://www.postgresql.org/docs/current/external-pl.html

I don't know specifics about the API coverage. It seems this extension mostly just implements new SQL visible functions and data types, which should be doable from those languages as well. Composite types might have to be defined as PG records (or json) instead of C level new PG object types.
