I’m so sorry that it got so bad for you. I recently quit my job because I was in that situation. I literally had nothing to do. I had maybe 8 hours of actual work a week. Paid really well to do basically nothing all things considered but it drained my soul. Being at home made it more tolerable but after cooking, baking, reading, side projects, getting my side hustle off the ground, exercising, starting an herb garden, taking up sketching, finishing my entertainment backlog, I don’t even know anymore I just couldn’t do it.

There’s something so terribly draining about having so much “kinda free time” where I might have to do random tasks sporadically but is otherwise completely empty.
I think the easy defense here is “do you really think my client would have known the price of those stocks would go up after that pivot?”
People fight over domains all the time.
I'm absolutely shocked that nobody has purchased the mines strictly to claim the carbon reduction from leaving the coal in the ground.
If you're living in China and b/vlogging about it, you pretty much have to toe the official line. Two of the most famous vloggers self-censored themselves extensively, but not enough, and had to flee China on very short notice:

Of course, this doesn't excuse getting paid for posting about how Xinjiang is all just unicorns pooping rainbows, like these jokers in the BBC article.
> 3.5 kwh/kg is probably 20 cents worth of electricity.

Your phrasing implies this is a small number - but 20 cents per kg is 20000c/tonne or $200 per tonne. The current spot price for iron ore is $200, which itself is twice as much as it was a year ago. So the additional cost of electricity could take the spot price as high as $400, four times as much as it was in July 2020.

It's still an important for the environment to do this & remove carbon from the industry, but need to acknowledge the costs.
It kinda depends on your domain and the way you structure your services. It's worth noting that, by saying "They throw 500 errors", you seem to specifically be talking about a single class of "service", ie web services, but the scope of "networked things that need to be resilient" is obviously much larger.

> Would it be better to bring the whole server down and have the operating system restart it?

It depends entirely on how you've structured your system. Some systems attempt to not-crash, but then cause repercussions on downstream dependents by attempting to continue when they shouldn't have. In those cases, it's better to just give up and die rather than erroneously continuing.

I'm not an Erlang user, but I _think_ the ideology is more along the lines of accepting the certainty that you haven't and won't account for all failure scenarios and embrace crashing as an inevitability and working backwards. You know it will certainly crash, so become really good at recovering from a crash.
Can’t it be because of ad-blocking ?
I mean, it's a pretty well known fact that what the people want doesn't actually matter.

Putting people in to prison for drugs is very important to the huge prison industry (#1 prisoner population per Capita in the world, baby), so in order to keep some people employed, we have to enslave some folks. It's a beautiful balance.

I think the author makes a valid point about this though - that it is precisely because of the limitations of SQL that we think this way. If SQL was a much more expressive data processing language we may not even require an app layer.

I do agree with this - after all SQL is supposed to be the data layer - why should we think that data processing shouldn't happen there?
This place certainly has its share of apologists.
ok. I see. Due to conservation of energy it takes energy to synthesize fuel hydrocarbons. So you might start with carbon dioxide, run it through some energy consuming process exposed to hydrogen and get hydrocarbons and water as the byproduct from the excess oxygen. I don't know enough chemistry to know what the exact synthesis method would be but I do know it would require substantial energy input. Thus the kerosene serves as a kind of battery. It is not a primary energy source any more. If this is feasible why not make carbon-neutral gasoline too?
My takeaway from this article was a familiar complaint for many of us: over-hyped new features being prioritized over more beneficial work. The key quote being:

> Tesla should focus instead on improving its actually-existing AI, its autopilot system. After all, the general idea of using computers to help humans avoid collisions is very good; we kill over 36,000 people a year with cars, so anything that drives that number down is worthwhile.

I think the author is saying that Tesla keeps promising a technology that seems to always be a few years away. But they could be saving lives right now with driver-assist tech that just isn't as "flashy" as full self-driving.

We're drowning under a mountain of tech debt and security issues (car crashes) that we could alleviate in 1 sprint, but the PM wants to add "cloud" to the marketing slides, so chop chop!

> All in all, it feels like Facebook thinks I'm an idiot and treats me accordingly.

This is the way of social media algorithms. I suspect it makes sense be cause the majority of users are indeed "idiots", in the sense of doing a poor job managing their subscription feeds and such. I'm sure they have tons of data showing how they improve user retention in aggregate by treating them like idiots.

But those of us willing to build and curate our own experience, we're the edge case not worth accommodating.

The Executive Computer; How to Improve a PC'S Math Skills (1986)
Hahahaha good catch. Perhaps if I'd used Lean on that string it wouldn't have happened.

I think the big choice is between using lightweight or heavy tools. Things like Coq and Agda take a lot of time to learn and implement but can derive 'correctly Haskell code which you can use, while TLA+ is more like a blueprint tool to check an algorithm before you write it in {favourite_language}. I think it's practical to learn TLA+ but if it's purely for intellectual satisfaction Wadler has a good book called Programming Foundations in Agda (I think?) which is available for free online.
From society's perspective, isn't it better if the solar panels all end up in large installations where they can benefit from economies of scale as far as maintenance, infrastructure, and installations costs go? As long as there is an empty warehouse rooftop in the sunbelt, there shouldn't be a residential solar install occuring. I say this as someone who had a solar install on his old house, but still, the costs should have been such that it discouraged me and encouraged industrial installs.
The painted one is sorta funny, such a low tech solution. I recently came across this interesting tidbit: "Cattle grids are generally useless for containing goats. However, a Texas Highway Department official reported that adding three 20-inch (51 cm) painted stripes—arranged yellow, white, yellow—on the road in front of a cattle grid deterred goats from approaching or crossing the guard."

I'm a US tech person in my 20s who does not use Twitter, Facebook or Instagram at all.

I do miss out on things because friends and family use Facebook for event planning, so I have to hear about things secondhand from mutual friends. But I never feel like I miss anything from the others.
lol never thought I'd tutor Korean in HN, but why not... :)

> But I’m not at all sure what role 걸로 ‘thing-WITH’ is playing in this clause.

It's a bit cheating, because 것 "thing" is kinda special and combines with the preceding verbal clause to create a noun clause. A better translation (if I were to teach Korean) would be "that". So, "이런 문장을 쓰신 것" is "that [you] wrote a sentence like this".

-으로 보다 (literally, "see with X") is an idiom meaning "considering X" - so "... 걸로(=것+으로) 볼 때" means literally "when [I] see that ...", or more naturally, "considering ..."

Also, the auxiliary verb 보다 (try - or "see" when used as a main verb) is a bit harder to explain but less forceful than English "try", which sometimes implies a lot of effort. Korean 보다 is similar to usages like "Please try this cookie!" or "Sure, I'll try walking next time." In our current sentence it's more like "[you] didn't have any experience studying ..."

Final "것 같네요" uses the same "thing/that" which takes the preceding clause, and "-것 같다" is an idiom meaning "I guess ...", i.e., "I guess that you haven't studied ..."

So, I guess you got most of the grammar right from very few clues. :)
Surely unless you are a doctor yourself, you cannot perform the clinical trials needed to arrive at an objective conclusion in just a day's time. So you must be relying on studies published by--gasp--experts!

Phrased differently: Give a general practitioner a day's notice to read up on an obscure disease, and they'll surely run circles around YOU.
That’s why you have a pump to move the water horizontally into different tanks. Then there is a 100m column and a 95m column forcing the water through the membrane.

So the pumps still need energy by “very little” energy because they are doing relatively little work.
On a tangent, I've experimented a lot with lucid dreaming and dream clarity as well as our recollection of it varies a lot depending on how deep asleep you are. When I'm calm and the dream is stable the visuals are incredibly sharp and detailed. I'm often amazed how lifelike it is.

One issue seems to be that dreams get fuzzy as we start to wake up and our memory of dreams is often seen through a fuzzy lens even if things were clear during the dream itself.

I've especially noticed this last part when being amazed at the detail and describing it to myself as I inspect it. Then I wake up and the memories are hazy and lacking the details I described.
The meat here is in the PDF downloads, particularly the full report: https://www.bp.com/content/dam/bp/business-sites/en/global/c...

The headline summary: the biggest reduction in global energy demand since 1945, of 4.5%, lead by oil but also in coal and natural gas. Renewable energy grew despite the overall decline. The US and Russia lead in national energy use decline, China's energy consumption grew 2.1%.

BP's annual report on global energy usage has been published since 1951, this is the 70th edition.
Will any GPUs work on the Raspberry Pi? [video]
People impute alternate meanings to words all the time. Such as "nasty" being flipped to meaning "cool". There's nothing constraining people from using emojis to mean things different from what they are defined to be.

For example, the wallstreetbets subreddit has their own local meanings for various icons.

Note that all alphabets started out as emojis. The vocabulary was, of course, very limited, and the emojis gradually got shortened, simplified, and turned into a sound, then stringing the sounds together meant a rich set of words could be formed. Did you know that the letter 'A' was originally a picture of a bull's head?
Unfortunately, it only took me half a sentence to know what this was about...
You realize that we aren't building any more coal plants in the US right now right? Tons of coal plants are shuttering all over the country every year. Coal has been going down every year for a long time in the US. There aren't any new coal plants currently planned anywhere in the US.
That is interesting! I haven't noticed discrepancies between Yelp and Apple Maps before, but now I feel like I'm going to have to start checking more closely. My assumption -- which now seems shakier -- is that if you reported an issue through Apple Maps, it basically got forwarded to Yelp.
> it’s good to look at areas where we can ‘make hay while the sun is shining’

I hope not, it would be really backwards if we had to adjust everything we do to sunlight. Imagine if you can't do proper work during rainy seasons?
There are even higher benefits by reducing the transmission and distribution requirements. T&D is hugely expensive, and local installs of solar reduces costs for the neighbors of whomever get solar installed.

Industrial installs are encouraged by utilities because they increase dependence on expensive, centralized, infrastructure. And for regulated utilities, this sort of infrastructure expense is easy to rate-base and increase profits.

But independent modelers that have been looking at fine-grained grid modeling, like Christopher Clack, have found huge cost savings by deploying massive amounts of storage and solar at residential and C&I locations first in the coming years, before doing larger industrial scar installations.
More confidence in your ability to make more money in a different investment is all the explanation you deserve(?).
I think it’s a need in the sense that it’s a safety net.

Being isolated and happy for months at a time definitely seems plausible. But if life gets hard, and you succumb to dark thought patterns, addiction, or a depression, very very difficult to pull yourself out of it by yourself.
Powering a whole house at night takes a lot of batteries. There's not enough battery production on Earth to even accommodate that.
The need for a certain portion of the internet to defend Musk at all times is absolutely weird.

In a funny twist of fate, so many people die while installing panels that it “kills more than nuclear”. Therefore, although I hate the shenanigans they pull off to overcharge, maybe they really deserve the money to be able to do things safely.
> AC is going to become essential as temperatures rise, the grid can't support the load

What are you talking about? Electricity consumption due to AC is absolutely minimal, much less that heating houses in winter.
> Exactly. I read so many posts on HN about living alone in the middle of nowhere being better than driving 2 hours each way in terrible traffic to sit shoulder to shoulder in an open plan office. There are lots of downsides to living in the middle of nowhere, healthcare, access to other resources, etc.

If those are the baseline options, then it's really easy to have the best of both: Have a nice comfy property 100 miles from a city, then make visits to the city outside of rush hour so it takes less than 2 hours.

(Though honestly 20 miles can usually get you quite rural.)
I bought something from one of these ads last summer. It was supposed to be a battery powered pump (like to blow up a pool float). The thing that came in the mail was just a cheap hand pump. Moral of the story here is be careful of these products. I assume lots are bait-and-switches like what I experienced.
> But in Thailand defamation is a criminal offense that carries jail time. And since Unsworth is a national hero there's little doubt the court would have found in his favor and Elon would have had an outstanding arrest warrant.

While Thailand is certainly within their rights to run their justice system how they want:

1) The punishment doesn't in any way fit the crime.

2) "He's such a hero" is a terrible reason to do something. Focusing on who the person being wronged was is a bad path to justice - it is better to focus on what the perpetrator did.

So I hope the courts in Thailand would have found in Musk's favour.
> It seems you’ve never been in a sunny climate without aircon

In Japan, in summer, you don't survive without aircon. 35 C with 90+% humidity, fans and opening windows won't help you anymore.

Australia has dry summers in comparison, which is really easy to withstand
That's a good idea. A demonstration of that old phrase "birds of a feather flock together." Musk employs a sleazebag to do Unsworth dirty, gets done dirty himself. Or maybe karma is a better word for it.

I don't know about that putting on a pedestal thing. Musk is a brilliant guy, but has demonstrated that he has a pretty rotten character. IMO, a good role model for a kid really needs to have good quality of character above all else.
To almost all of the questions, 90%+ of the advisory board voted no/uncertain, yet FDA completely overrode/ignored their advice... I would understand if it was 50/50, but what's the point of getting an independent board if all of them tell you no and you still say yes?

> In his resignation letter, Kesselheim said the agency’s decision on Biogen “was probably the worst drug approval decision in recent U.S. history.”
Well given that all but a tiny percentage of the energy consumed that’s not waste heat is either going into useful computing or keeping fans spinning (which you would have in any sort of HVAC solution), I’d say it’s super efficient.

If you're running a web server running the Phoenix framework on Elixir, and you're processing a request and an (unhandled) error is raised, the request fails with a 500 and the rest of the web server runs fine, other requests process normally, the whole elixir/erlang/server process keeps running.

The "let it crash" is referring more towards letting the specific operation you're operating under (i.e. a single web request, a scheduled job, an async method, etc.) crash, and let the thing supervising it handle the restarting of it.

Processing a request and running in to a "let it crash" scenario doesn't mean bringing the whole thing down, it means the individual request crashes, the web server supervising it catches the crash, sets the connection to have a 500 status and returns, and life goes on as normal, the rest of the process being unaffected. In other similar scenarios the supervisor may want to restart the process after it crashes, or do something else in response.

In general the ethos of erlang(/elixir) is to let things crash but more importantly have the process supervising it expect things to crash and know what to do next to recover from the crash.

It may not be a novel idea nowadays (especially with web servers where presumably every implementation among every language will catch exceptions and send a 500 error), but it was a design principle when Erlang was being made, and it's baked in to the language and runtime in a fundamental first-class way where every Erlang/Elixir application you run is a supervised tree of processes that care about what to do when a process under it crashes.
Perhaps another succinct phrasing that might be more easily grokked without spending time working on Erlang systems is:

"Let it rollback and retry"

The way one thinks about processes in Erlang is different than how one thinks about threads in most languages. The expected behavior when you kill a process is that it will be right back up with a known good state very quickly, and you won't have to do much about it yourself because it's handled in a supervisor far from your local process. It's subtle, but it makes a huge difference.

In most languages one expects a thrown unhandled exception to wreak havoc. But in Erlang graceful failure and restarting is the norm, not the exception. It's the expected behavior.

Moreover, the responsibility of maintaining the process tree integrity is delegated fully to specific processes. "Business intelligence" (to ape a phrase) nodes are very effectively isolated from having to care. If they don't know how to handle such a restart, you just let them crash/be killed and restarted too.
Yeah I’m not professional (I have a BSc in mathematics) and all this looks fairly introductory. Moreover there are lots of easy ways to calculate these constants like Pi (like taylor series) not even mentioning e can be easily calculated to whatever precision you need from its definition
I took no offense to what you said. I think solar leases are a complete scam. The sales person sold the elderly couple an undersized system that left them still paying for electricity from PG&E every month. And a few years from now, I will be paying more per kWh than from PG&E. But the delta won’t be huge so based on the discount it was okay with me. But yeah it’s incredible that Solar city sold these people this lease, it’s practically useless for them and it’s definitely useless for me.
I loved using spot instances for managing scaling for a startup i worked at, saved alot of money instead of using these services they provide.

Interested in this statement, because I’ve always read and been told not to put pet waste into the compost; the rationale being that they can carry viruses that you can then catch if you eat what grew in it. Is guinea pig poop special, or do you have a particular method to avoid that?
> It's the 3rd smallest number of the most recent 15 years. Smaller also than 1906, 1907, 1910, 1913 and 1914.

And the 3 largest were 1.27M, 1.18M, and 1.13M. For the last 20 years legal immigration was at an average of 1.06M/year, and the year-to-year differences were negligible (except for 2003) (yes, including during the notoriously anti-immigrant Trump presidency, that averaged 1.08M legal immigrants/year). So ranking them in terms of Nth smallest/largest makes little sense - you're studying noise.
