Maybe I'm misunderstanding your problem statement. But it seems to me that you are using (and paying for) N units from your regular provider. And then your community solar operation is selling S units to the grid and giving you a monetary credit (the result of the sale) instead. Some customer (due to fungibility, it could be you or anyone else) is getting those S units, and paying the community solar project (indirectly via the grid). And those S units are displacing some other set of S units that were previously generated by fossil fuels, which is (presumably) one of the main goals of this entire exercise. So maybe the answer to your final question is actually "only N units were actually generated, because the fossil fuel plants ran less and produced S fewer units".
>I don't understand why Softbank won't just put it back to the public market and list on the LSE.

Softbank is a grossly mismanaged shitshow fueled by an endless money well of Saudi money.

Don't expect it to be behaving rationally.
They already sell hundreds of millions of units of their SoCs - the Nintendo Switch runs on an (ARM-based) NV SoC for one example and has sold over 70 million units.
I am sure the Postgres full text search is pretty good by now. But I always expect projects like these to eventually reluctantly switch over to Elasticsearch in order to handle 10-20% of the queries better.

Great explanation, sorry for confusing things.
NVIDIA has already released customized ARM chips, like Denver: https://en.wikipedia.org/wiki/Project_Denver

"Denver's binary translation layer runs in software, at a lower level than the operating system, and stores commonly accessed, already optimized code sequences in a 128 MB cache stored in main memory"
Will they be in the $1200 price range, the op has mentioned?
Cryonics simply assumes the eventual development of molecular nano-technology per Drexler is able to repair both the freezing damage and any medical problems too. Not at all unlikely in a few decades, and almost certain within a century.

As for who would want you back ... your children, hopefully. And if there's no repair before they die ... hopefully their children would want them back. Etc.
My guess is that there will be more full-time remote jobs. But I do expect that most of the tech jobs being discussed will still be attached to an office with a general expectation that teams get together semi-regularly. So long as it's only one day per week or less, that gives people a lot of flexibility in where they live but it does mean they probably can't move to a ski town.
>Please stop repeating the "testosterone==aggressiveness" falsehood. There isn't a 1:1 correlation.

i didn't say "==". I stated "->", i.e. positive causality from testosterone to aggressiveness (The opposite is obviously not true as evidenced by aggressiveness without testosterone, say in women).

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3693622/#:~:tex....

"Atavistic residues of aggressive behavior prevailing in animal life, determined by testosterone, remain attenuated in man and suppressed through familial and social inhibitions. However, it still manifests itself in various intensities and forms from; thoughts, anger, verbal aggressiveness, competition, dominance behavior, to physical violence. Testosterone plays a significant role in the arousal of these behavioral manifestations in the brain centers involved in aggression and on the development of the muscular system that enables their realization. There is evidence that testosterone levels are higher in individuals with aggressive behavior, such as prisoners who have committed violent crimes."

>Also you are implying that natural selection is currently existing in human society. It does not.

natural selection never stops. Some people naively think that the "fittest" necessarily means strongest/healthiest/etc. which is just not the case.

So, then it comes to the drivers, one can say that societal natural selection is less "natural" (in that very naive understanding of it) and more like selective dog breeding and similarly it works very fast. Add to that the positive feedback between testosterone production and testosterone style behavior - ie. the more testosteronish style behavior of an individual causes more testosterone production in his body and vise versa (that famous barn swallow experiment where they painted the male bird chests dark to fake high testosterone characteristic or the article referred above:

"Several field studies have also shown that testosterone levels increase during the aggressive phases of sports games. In more sensitive laboratory paradigms, it has been observed that participant’s testosterone rises in the winners of; competitions, dominance trials or in confrontations with factitious opponents.").

> The wonderful thing about the Fediverse is that depending on the node you connect to, or the people you choose to federate with (in the event that you have your own instance) that your experience will be vastly different.

The same argument works with Twitter, and I genuinely believed so a decade ago (Twitter has been the only social network I still continuously use). I don't buy it at all after the decade-long experience. Your favorite followers will fight to each other no matter you've carefully chosen them. No amount of filter solves your timeline being messed.

All social networks do not work, federated or not. I'm going back to the good ol' IRC or whatever it follows.
Sadly something being inhumane isn't a legal defense. It has to be cruel AND unusual. If its cruel and common its A OK in the USA.

I think dry casks are dangerous "forever" and therefore the costs of securing and managing them is effectively infinite.
The sad thing is so few companies really invest in participating in FOSS software. That’s one reason these “open source companies” came to exist. It really should be a community of contributors, backed by a diverse set of companies. At best, employers will allow contributing bug fixes or small patches. Not the in depth dedication these projects really need.

We’re heading towards a handful of giant companies that can afford to pay large teams to build and maintain FOSS, and hence own developer mindshare, for their own selfish reasons.
It's a fork of es40. New build system, more stable networking, bug fixes, but don't expect miracles just yet. 10 year old c++ codebase is not something you magically speed up overnight

Googling a bit: it takes about 13 MJ to desalinate 1 m^3 of water by reverse osmosis. Seawater contains 3mg uranium per m^3, which gives 2 MJ, So it's not energy positive.
I really don't get why the concept of mastodon is so confusing.

It's basically twitter/microblogging* with multiple hosts, and you can see posts from other hosts. So instead of just @andrewzah, my handle becomes @andrewzah@<host-I-chose>. You could visualize twitter as @andrewzah@twitter.com, but it's redundant as twitter is the only host. This is basically how email works, no?

The only other difference is federation, so you have two timelines instead of one: the entire** federated timeline, and the local timeline to your host. Plus the timeline of users you follow.

So unlike twitter, the user must decide what host they want to use. Or they can self-host an instance. I'm not sure if it's up to date, but https://instances.social has a wizard for this.

*: IIRC mastodon's default limit is 500 chars, and pleroma's is 2,000.

**: One exception: Hosts can block other hosts. So if you use i.e. mastodon.social, you won't see posts from users on blocked hosts unless you specifically follow them.
They make some systemic criticisms about the security of decentralization on top of making recommendations to potential users:

- Use RSS feeds generated by mastodon / pleroma.
- Contribute to stackexchange and hacker news.

If it wasn't for those recommendations the title could better represent the content.

honestly, who cares anymore? last thing we need is yet another monopoly, this time in the EVs industry. AAPL is known for innovation, but in reality, they just take their time until the other competitors have already solved the main obstacles and sold the idea to customers. Then they swoop in and offer an overpriced luxurious product and claim to be the first and the best in the business.

There was a paper I saw a few years ago that showed a high correlation between the diversity of a lab (racial, cultural, income, political, age, anything they thought to measure) and citations of published work.

My personal experience is the more diverse a team in software, the fewer blind spots the product will have. This might not be something you always care about, but I think in general it leads to better products, since all that input can be very valuable. I would say by the time you have 30 employees you have had a lot of opportunities to not hire an echochamber. Of course you’ll get some diversity just by hiring different roles. Even just having senior and junior devs rubbing elbows is a good start for diversity, and even if it doesn’t make your product better, you’ll find the two groups have different tasks that are morale tarpits, and you’ll tend to have a happier team.
I’ve had an idea like the is for a long time but for a distributed social network.
Why people talking about climate changes always seem like a religious debate?

Yeah nuclear has advantages and disadvantage, same apply for solar, wind, geothermal.

But all these technologies have a role to play to solve climate change. Can we stop having these stupid religious debates?

Does anyone has a link explaining one realistic way to solve climate change without going into ideological debates?
Germany uses ~30% Coal in its energy mix, France less than 2%.
Your argument is misleading at best, and targeted misinformation at worst.

Since you've repeated the same argument at least 5 times by now, even though others have informed you about the wrong conclusion, I must assume it is meant to misinform.

How could this be improved?
In a way you're right, there are a bunch of commands. However, they are pretty straight-forward and simple. And that's only required for the initial setup.

Your comment already assumes that just because a person can type in commands on a terminal, they need to know about version management, nginx configuration and letsencrypt setup.

If you look at the site docs [0], it further syncs from local to remote.

Also, in many cases all the overhead that we, as software developers assume we should have for everything, need not be the case for just a simple website.

I'm glad Racket CS happened(even though I don't use Racket), because I was worried about the future of chezscheme's maintenance. It's a runtime with good portability(Guile Scheme, for instance, seems to pretend Windows doesn't exist), and I think it'd be a shame to see it fade away in the future.
Vietnam rooftop solar records major boom as more than 9GW installed in 2020
I bought my house about 4 years ago for 162K, and am about 45 minutes from a major Midwestern city (Chicago). Plenty of shopping and entertainment, high speed internet, recreation all within reach. Tech salaries are around 6-figure for many jobs (systems engineer), higher for developers. Oh, and if I felt like doing handy-man work, I could have gotten a house for 90K (would be livable, but require renovation to make it "good").

> many people are determined to live in a way where their reach always exceeds their grasp.

You mean being able to pay the rent, send their kids to university, pay their medical expenses without getting bankrupt? Because that's the kind of life most people aspire to.

> You can't outrun financial idiocy.

Following this line, most people are financial idiots, which means they are responsible for their poverty?
People preferring detached houses is fine. Just take off the subsidies and let the market choose the mix between suburban houses and high density housing.

It is literally illegal to build apartments in many areas of the United States. That's because of local zoning laws limiting how many residential units are allowed per acre, minimum parking requirements, height restrictions, setback requirements, etc. The US government intervened in the mortgage market to make low interest 30 year loans broadly available (if a homeowner defaults and the foreclosure sale is not enough to cover the loan balance Fannie Mae & Freddie Mac are the investors holding the bag). Toll-free highways make commutes from suburbs to downtown possible.
Well now I am even more impressed, because I think I managed to sell to two or three universities in the EU, and even there I'm effectively losing money because of all the hoops one has to jump through.

Again, congratulations, I'm really happy for you and wish you all the best.

Interesting article, but I disagree with the conclusion. Smart car style vehicles never really caught on. They have a poor user experience. Cramped and they don’t feel very safe. Most people can’t ride a motorcycle either. They’re cool, but Apple isn’t about to target a specialty market with a play like this.

I theorize Apple will produce a car, but surprise us by having zero ownership. It’ll be entirely plan based, a service subscription to compete with Uber. They’re just waiting for self driving to be feasible, so there are no drivers required.
Not at all. Cities are crowded af. With more of the population dispersed, we can redesign urban life with more living space, create more parks, support more robust urban farming, etc. Cities wouldn’t look the same as they do today, but I think that’s a good thing.
> It lasted half an hour, caused a trillion dollars to be wiped off the US economy and was followed by investigations and a congressional hearing.

A bunch of things:

- that wasn’t an outage, that was actual trades taking place at significantly decreases prices. Not even close to the same category. Those same exchanges involved in that crash literally go offline every evening and on holidays/weekends and nobody cares. In fact, if the exchanges had gone completely offline during that time period, it wouldn’t have even made the news because there wouldn’t have been a place for those trades to occur.

- it didn’t cause a trillion dollars to get wiped off the economy any more than my friend transferring a share of Apple to me for $0.50 causes a trillion dollars to get wiped off of the economy.

- nobody gives a shit about a “congressional hearing”. Do you realize how many congressional hearings tech companies have been pulled in front of now? A hearing != action and if you think otherwise, there has been significantly more “congressional action” over tech companies in the last couple of years than financial companies.

> If you think Twitter has a problem with adversarial clients connected to its network I think you don’t understand the modern financial market.

Show me the public IP address of NYSE or whatever major financial exchange you want that I can connect to from any IP in the world. If exchanges were open to the world, they would get DDoSed out of existence in a heartbeat.
> - compared to Signal, it does not snoop your phone number

Great, leaking the user's email address which, more often than not, contains their real name is so much better. /s

Seriously, though, I don't think this comparison accurately reflects the differences between Delta Chat and Signal:

Signal uses your phone number for account lookup but not for addressing participants. Moreover, it uses a feature called Sealed Sender[0] to conceal even the cryptographic address of a message's author. In contrast, Delta Chat leaks the email addresses of the people participating in a [group] conversation[1] (and, thus, their social network) not just to one provider (as in the case of Signal) but to all email providers involved in hosting the conversation, meaning that, as a user, you have to trust not just a single but multiple entities. Meanwhile, Signal doesn't even know how many people there are in a group conversation.

I live on a beach in my 30s with relatively meager income compared to other people on HN and I constantly meet expats aged 60+ who live at the beach, happy to finally retire after 40+ years of grueling work so they can finally live at the beach.

I'm glad I snapped out of the delusion that you need to waste your youth working so that you can finally enjoy life when you're old and have trouble getting a boner.

We have a cultural problem where we don't use money to buy time. We instead use money to buy everything else. You're usually looked down on for making the time trade, like some sort of deadbeat who doesn't want to work hard. We make day to day decisions as if we were immortal.
This highlights the fact that there are too many protocols that are essentially reinventing the wheel. The problem isn't necessarily too many clients, but too many transport agents.

In a way, they're almost all reincarnations of what email, IRC or XMPP could already do, with a few makeup changes, often designed to lock-in the user and consequently fragment the user base.

What we need is perhaps more clients, with different interfaces but using the proven underlying protocols and implementing new features client side. Delta Chat, making use of email, does this, with the added bonus of SMTP's natural decentralisation and openness.
My first thought after reading the headline: About an hour or so...
All those things are themselves good, and unplanned families are not good.

Falling population is good, working shortages will increase the demand for automation and result in worker dignity. We simply need a fuck-ton of immigration to amortize things a bit, until we get to post-scarcity post-growth steady state in 2100.
How can we spin this as a bad thing, right?
Like a lot of open source projects this is a great idea with a lot of potential that's somewhat let down by poor design and UX, we really need more professional designers contributing to open source!

eg: How do you start a new chat – the primary function of this app? It's hidden in the "..." menu that looks like it contains the settings for the existing example chat.

Fidonet used to provide the federation across message boards in the BBS era, so there is literally nothing new.

Well, as they say in Texas: "Don't let the door hit you on your way out".
His description actually sounds appealing to me. Some areas have different cultures they fit some people and not others. It's just how it goes.
On a large time scale solar seems like the right call, even over fusion. I keep hearing about storage issues, but that seems trivial given the complexity of our current energy landscape.

Humanity is hopefully progressing toward a Dyson sphere... which is just maxed out solar.
Uh, what about the yearly production of nuclear waste by the French energy sector? Do they have a long term solution for that? And what about decommissioning old power plants? They’re currently deciding whether to run them another 10 years beyond their 40 years design lifetime. (Great way to postpone a problem, by the way)

what’s not clear from the FAQ is whether it turns ALL your email into chat messages or only a subset, e.g. all email with a special header or tag in the subject.

I’m assuming it piggybacks on your normal email address as opposed to making you create a dedicated one for chat.
