> If I have a home solar installation that can send up to 10KW into the grid, how is that any different than an EV battery that can send the same amount of power into the grid?

Your system have a purpose: give you energy NOT stabilizing the grid. Your system (like mine) actually disturb the grid and that's why countries have regulations on them. The actual grid have issues ALSO due to the augmented presence of p.v.

If you want to stabilize the grid with cars you do the very opposite, your system need not to give you energy using the grid as a kind of "energy buffer" but to be itself an energy buffer. Let's say we have such systems: at a certain point in time locally our domestic power plants see a sudden frequency drop, around 1Hz. As fast as they can they start pushing energy to the grid. All connected vehicles/plants. As a result the frequency peak in 2-3". Again as fast as they can all connected systems try to get energy from the grid to help the frequency going down. Again a network effect. The frequency drop. They reverse. In a minute you have generated enough oscillation that no one is able to keep the frequency, local grid segments got disconnected, all generators in the segment shut down.

Few big enough power plants can coordinate themselves to monitor and decide, too many small and spread can't. Even with frequency shifting witch is the fastest and simplest way possible we can't.

Trying proving the above: if you have a monitoring system fast enough, like an MQTT frequency sensors or a multimeter with frequency measure and graphing ability try to see a minute at night, with pv disconnected, no battery etc and a minute when it work. On grid ONLY you'll see a far more stable frequency. On p.v./battery you'll see a schizophrenic variation. Try to interpolate at a grid scale the resulting mess.

If we just inject to the grid our inverters simply try to push energy watching frequency, they push less as the frequency goes up but nothing more. It's up to the big power plant regulating. Being one-direction only they generate disturbances but still something manageable at least at a certain scale. A bi-direction system I can't really say if it's sustainable nor I know if a far bigger presence of p.v. can be allowed...

Edit: sorry, forgot a part, yes you can recharge and EV even at 100W but the battery do not balance cells, as a result it last less time. Witch means for instance 8 years instead of 10 of usable life. 7kW is generally the "needed mean" to balance for most EVs, normally you have such issue mentioned in the manual.
Remember, if you see someone stealing food, no you didn't. Shoplifting is a systemic issue, hiring rent-a-cops to crack down on poor people is looking at the problem from the wrong end. Challenge the elites. Build a better system.
No, but they have food in the cities they decide to camp in, which are selected due to weather, social services (e.g. calling Seattle as "Freattle"), and lax enforcement of camping rules.
I don’t think the US is easy to
emigrate to for extended periods of
time. I am put off by being tied to one employer in an at-will employment culture and needing that job to stay resident.

Wikipedia says 188,100 new and initial H-1B visas were issued in 2019. So not a lot.
I remember when homeless employees working for Google made headlines. People had good paying jobs, couldn't afford housing - or at least didn't desire to put the entirety of their income into housing. Looks like things may be headed back that way again.

Bananas is also an example of this process of “GMO-by-hand” stopping due to economic reasons, leading to monocultures susceptible to disease, twice as I understand it.
Ask HN: Trillions of new Dollars and Euros have been printed – where are they?
In the USA, about 5 Trillion have been created:

https://fred.stlouisfed.org/series/M2SL

In Europe it was similar. Also trillions have been created.

Where is all that money?

It must be on the bank accounts of some peopl, companies, institutions, right? But where? And how did it get there?

I for sure do not have it. My bank account did not get bigger during Corona.

Any "Corona winners" here?
It's really interesting to me at how sensitive Americans (in particular) seem to be when it comes to property damage or theft while being completely uncaring when it comes to people starving, getting bombed, getting shot, living with violence, being literally killed by our health care system (eg insulin), dying in the streets or people being denied life-chaning or life-saving medical care.

I don't support stealing but there are different kinds of stealing. There's a difference between stealing cars and stealing diapers and baby formula.

Property crime (and many otehr kinds of crime) are a symptom of extreme poverty and wealth inequality.

Policing here isn't the answer. Nor is incarceration. If it was, the US would be the safest place on Earth since it has the highest rate of incarceration in the world (4% of the population, 25% of the world's prisoners).

At some point you have to realize this issue will only be dealt with by addressing the underlying material conditions of the nation's poorest and most vulnerable. The link between poverty and crime has been known for thousands of years yet Americans in particularly doggedly refuse to acknowledge this.
Managing the data plane is the more complex part of it as you would expect.

I do tend to model the business processes at a high level using domain-driven design and map the aggregates to services that ingest event streams. The services then react to the event streams in several ways: emitting events, updating control plane models, issuing new commands to other services, etc.

Each service keeps its own state internally and if I need to, I can blow away their state and replay all of the business domain events thanks to the durable message stream. That part is key... and is also the most duct-tape-and-toil area of this architecture.

I've been toying around with ideas to generalize this into a consolidated application framework but it's still pretty experimental stuff.

The high-level architecture isn't terribly novel or new but having standardized tools for common operations, managing migrations from event schemas, managing checkpoints, etc; is still a work in progress.

> All power generation is subsidized

My point is, the combination of wind, solar, storage is orders of magnitude less subsidized. If you account for risks (nuclear) and externalities (fossil fuel). This is not propaganda. But your claims about nuclear are.
Ask HN: What Makes HN Addictive?
Because batteries can pump out magnitudes more power in a very short amount of time than solar. The two are not comparable.

But ultimately, what speaks more than anything I could ever say is the requirement for backup power generation (including household battery arrays) requires mains power be cut off before engaging - to prevent damage to the grid.
Does William and Mary sell T-shirts with only the word "the" on them?
More people steal to "survive" that you probably realize. In my experience with lower income college graduates (arts degrees, for instance), the question of where to go to steal food for the day is a common discussion point. Could they survive by going to food banks instead? Probably. Or by taking any other job. But stealing is easier, less "degrading", and more inline with their career goals.

That said, the system works. Some people get small personal servings for free; others pay extra for their full family's meal so the store can make up for the breakage. It's that same terraced pricing structure every SASS loves.

I like the idea in theory, but basically all systems currently in use, are good enough to run "pseudosimplicity" programs without trouble.

We don't need to make stuff all that lightweight, Moore's law seems to have won. We just need to not invent a new way to make things horribly slow or otherwise bad, like, by not making stuff cloud first or have a mandatory blockchain feature.

Of course, a movement can be about more than one thing at once, and if the permacomputing community values through and through simplicity for it's own sake, I can't argue with that.

Could you explain why this is important?
I will definitely give this a read. This is an idea I happened upon and have developed informally so it will be very interesting to read someone who has codified it a bit.

It's interesting to me that casual civics and history instruction spends so much time on the bill of rights, democracy, etc and yet the system of "private property" which to my eye appears even more fundamental than our constitution to how things work in our society is taken for granted.
2nd-factor WebAuthn should work fine with Android phones today. Any Android phone with a current version of Play Services and Chrome should be able to scan the QR code, if it doesn't work then it's a bug (or, at least, an old QR scanner).

Huh? In my city, shoplifters can walk out with 70 inch TVs while the police watch them do it (shop lifting is decriminalized). Everyone who isn't a shoplifter is pretty pissed off about it, I think the police are there to prevent mob justice from happening.
> Right now 100 years old houses already exist and can be restored/upgraded with a minimal amount of work (in terms of energy and emissions).

Having lived in one, I can assure you that upgrading such a house to modern energy standards isn't a minimal amount of work. Lots of these houses just have a single brick wall directly facing the outdoors. Insulating that means you have to basically completely strip the house down to the brick, and even then it won't be as good as new construction.

Of course demolishing and rebuilding also takes energy; but if you amortize it over 50 years or so, I bet in the end you come out ahead. Building technology has improved a lot in energy efficiency over the last century.
> You do not comprehend the literal scale of the problem.

No, all it needs is a reasonable tax system without loopholes and where taxes are well balanced and of course reasonable services provided by the state funded by these taxes.
With apt2ostree[1] we use lockfiles to allow us to version control the exact versions that were used to build a container. This makes updating the versions explicit and controlled, and building the containers functionally reproducible - albeit not byte-for-byte reproducible.

I never understood it, either. It would be useful (at least historically) in cases where you’re willing to give up performance in exchange for lower memory usage, and then, you’d still have to make good choices on what strings to intern and what strings not to intern (I think the standard example is a XML parser that may choose to intern all node and attribute names of a XML schema. If you’re parsing a large file using a DOM parser, that can significantly decrease memory usage)

Problem 1: it can easily depend on your input data whether interning is necessary to prevent out of memory exceptions.

Problem 2: there often are better solutions to memory usage than interning strings (for example, by replacing that DOM parser by a streaming one)

Problem 3: if you’re writing a library, you can’t know anything about the application that will use your code, so you have to guess whether interning some of the strings you create will help the user.

And of course, that’s historically. (Some) modern JVMs already deduplicate strings.
Unfortunately there is now a large section of the population that disagrees.
It might be a red flag. But that can't be some roadblock to entering the industry.

People get into careers for all sorts of reasons. A paycheck. The thrill of succeeding at their job. The thrill of being the best in the business.

You can't just exclude those people from that career and focus on people "the goals of the business". Personal goals are better drivers to excellence than business goals.

What's the law called where you can't tell if someone is being sarcastic or actually thinks the ridiculous things they say aloud?

"Stopping someone from stealing a notebook prevented a drug overdose death".

I hope you and folks like you realize that encountering rhetoric like yours only reinforces the thought that some people are just really out to feel like they have power over others, and some folks are capable of amazing gymnastics to support the cruelty of most Western capital societies rather than confront the notion that maybe you have no god damn idea why someone was stealing a notebook and maybe just maybe it doesn't fucking matter even a tiny little bit.

That will only work if you are on the same subnet.

When you craft a packet for that address, the stack will see that route and send an ARP "who has" request out whatever interface you assigned when you did that IP route rule (probably your default ethernet). If nobody responds than the packet dies in the stack.

> Does anybody find the constant promotion of Brave on HN annoying?

Sometimes it is, but in this case it's actually an hacker newsworthy innovation.

> Everytime I look at comments its the same handles who are also pro-crypto

I'm 100% not into crypto. I don't like it's environmental impact and I'm not sure it will hold value long term. That said, it is an area where a lot of really smart people are trying to solve big problems... and maybe something of great utility will emerge.

> I can't take a browser serious when there are conflict of interset especially monetary ones in promoting it in public

I'm not sure what you mean here. Brave makes money by doing something other than either asking for donations (Mozilla), advertising (Mozilla, Chrome) or selling your data to whoever (lots of smaller browser companies)? Brave's interest in Crypto is a little strange, but the have made a great product, they are actively innovating, and their browser is really a better chrome than the original.
It all depends on many aspects.

For example not so long ago I used Ubuntu MATE (whatever was latest) on my son's ThinkPad X220T.

I have three issues:

- 1st minor: After rotating screen MATE Panel moved in various places (xkill helps)

- 2nd minor: sometimes the Bluetooth or WiFi applet in tray area was 'doubled' (did not solved this one)

- 3rd major: after suspend/resume cycle I could not get WiFi to work (reboot required)

After failing to find solution for this WiFi problem on Ubuntu MATE I though that I will try GhostBSD there (based on FreeBSD STABLE) ... and these were my problems:

- 1st major: after suspend/resume cycle I could not get WiFi to work (reboot required) :>

So I left my kid with GhostBSD till now - also he likes the 'kernel messages' at boot comparing to 'silent' Ubuntu MATE boot :)

There are lots of cannabinoid receptors in the body and the body produces its own cannabinoids (e.g. Anandamide). There is no need for weed – when it comes to those receptors.
I don’t get the complaint either as Brave has really tight privacy and always had.

My personal theory is that people don’t like Brandon Eich because of the prop8 stuff from 10 years ago and throw shade for other reasons.

This seems to follow the playbook of “I don’t like you for a reason I don’t want to talk about so I’ll find something to criticize even if it is illogical.”

....because then containers can't network at all to non-local networks, e.g. no internet access. for bridge networks at least (which is the default).

by specifying the drop for new connections incoming from the external interface, you stop connections to listening services from external networks, but established and related connections can continue implicitly, so forwarding still works for outbound connections.

if you really want to block all internet access for containers, and stop anything else on your system that might need to use forwarding, then your suggestion is correct.
> Anything else other than the ability to reliably use == for String comparison instead of .equals()?

Sometimes that's key.

Why not use an int or some other token? Well then you have to garbage collect yourself. Maybe use your own class for the token though instead of a string? But then you still have to do half the garbage collection, as you need a weak map for lookup and possibly some cleaning infrastructure.
I see the exact opposite of these claims.
Neutral bots probe political bias on social media
By selling ads and services for normal money. The crypto is for the users to tip content creators with. Brave buys the crypto used to tip users with normal money ad revenue from the open market, as far as I know. That means the creators users gave tips inevitably have someone to sell their BAT to.

The issue is that idea that people are just desperate and stealing food is not accurate and used as cover for stealing everything with little consequence.
I dislike that kind of attitude towards the poor, it's infantilizing and strips people of their agency, it's like the modern "noble savage", just some others who are pure of heart and can only be corrupted by the evil influence of the system.

I've been dirt poor, I've been homeless, I've been alone in a foreign country with no one to turn to, I've lived in such shit places that my neighbour got shot down with an AK not 100 meters from my doorstep ... in Europe. I still didn't steal.

There are systemic issues which keep people down, that doesn't excuse immoral and illegal behaviour. I've known a lot of criminals, they're by and large scumbags, not some modern robinhoods stealing for the sake of their family because of capitalism.
"Pricing-wise, I'd say the all-in fees on a per dev basis are comparable to a developer's salary here in the US, the fees are all inclusive of benefits, tech equipment, offices, perks, etc..."

Well, then as a USA based org, I'd have to say - what's the point? If it's comparable to a USA dev Salary, what savings/arbitrage/win a I achieving here? Wouldn't it be easier for a USA based company to just corp 2 corp/1099 or such someone onshore, then offshore and have a middle man?
Maybe I am misreading or misunderstanding the article, but it appears that this "odd matter" is a powered, designed robot wheel with motors that cause it to roll uphill (or rather, over a hill) when powered.

Interesting idea. So you're saying that the oxygen will bind more readily to the carbon than to the iron itself, and carry it off as COx? I'm not a chemist but I know iron loves to bind with oxygen (i.e. burn) at high temperatures; that's why oxyacetylene cutting torches work so well.

Docker's behavior is unintutivie but makes sense given how container networking works. If you use UFW read https://github.com/chaifeng/ufw-docker and follow the guide.

Converting something that is promised as free, and especially after years of use into a paid service is extortion (the act, though not the crime).

We're all so complacent with terrible service from everything that we keep giving passes to very profitable companies that completely don't live up to some of the most basic principles of service provision.

Gmail is essential to many people now, changing accounts is like changing phone numbers... The attitude of allowing Google to simply shrug whenever they break promises, security, rules, and standards sets the bar for the entire tech industry. They should be held to a higher standard.

Their search and so many other things are tied into a very profitable network of information harvesting that can easily become weaponized against us all, it didn't start out that way at all. Just the ideal of them phasing out their slogan of "Don't be evil" was a huge sign of how they pivoted from promises to preying upon people. It's not a minor flub, it's calculated and quite irresponsibly conducted profiteering.
