This functionality is already there.

This is quite much. If you add other infra overhead, feeding power back into the grid is not going to produce much revenue for the individual unless the selling price is maybe 20 cents above the price when charging.

On the other hand, something that MAY make more sense, is if the car battery can be used to provide power to the owner's own house during short price peaks. This might allow some savings even in stable grids, but the killer app would be in grids that have rolling blackouts during high demand periods.

And even for grids where blackouts are infrequent, if your car can serve as large UPS for your house (combined with a large capacitor to keep the power stable), such functionality in the charger may be worth the cost of the hardware for many people. (Bringing the number of units up and hence the cost per unit down over time.)

Still, though, for grid stability it is probably much better to use dedicated batteries as part of the grid itself than to use car batteries.
UCSD Pascal was as much a regression/subset of (Jensen &) Wirth Pascal as an evolution of it. It did add things like a function "exit" (cf return) keyword, string type and separately compiled units, but on the other hand it only supported local goto, and didn't bother to implement dispose(), instead opting for an odd stack-based mark() and release() scheme (i.e. there was no way of freeing an individual item allocated with new()).

The USCD P-System spec is here, for anyone interested:

The answer to too much foreign investment money in real estate is... more domestic investment?

Why must real estate be an investment at all?! People need to live somewhere. If they can own where they live so much the better.

How about a land value tax?
Do people on HN not read history books? This has happened countless times before.

Or was it assumed that those in the tech industry were a "protected" class of people for whom the rules do not apply?

Hell one of the best things about capitalism: everyone is equal before the dollar and everyone is expendable.
So people being asked to discharge their Tesla into the grid should be paid a significant premium, right?

Since they are providing power on demand in a way that doesn't have upfront costs, that should mean that car-based power demands a cloud-like premium (10-50x over traditional servers) over traditional power plants.

They are getting a little premium today, but likely won't once this practice becomes normal.
I'm a bit surprised Chromecast is still kicking. It used to be a pretty unheralded innovation which I found to be really useful. But, honestly, these days I usually have multiple other options to get most content up on a TV screen.

The "160 gigabytes" text was linked to the Johnny Mnemonic wikipedia page, so it it possible they're just exaggerating and meant "it was growing at a rate we didn't expect or couldn't really sustain"?

This got me wondering, I created a Mastodon user @ defcon.social and my first couple of posts were images, just to test things out and get started with my chosen client - Ivory by Tapbots (the creators of Tweetdeck, RIP) after tptacek spoke glowingly of it here. Then I realised that by posting those I'm basically taking up space on a community service without paying for it, and I wasn't sure exactly what the etiquette was. On a commercial, monetised service like Twitter it's different as there are advertisers (or at least there were...) but afaik "defcon.social" is just a non-profit and I'd really like not to be a big cost sink.

Also I wondered if there's any overhead involved in following users across many different instances - if my @defcon.social user follows a bunch of users on various other instances does that place additional burden on their mastodon instance or just on my local client?

Might be time for me to read the defcon.social fine print and T&Cs (I only glanced over it) or even about Mastodon/ActivityPub generally...
One of my undergraduate literature courses was on postcolonial studies, so unsurprisingly we talked about Bhaba quite a bit, and I was confused for a second just like GP. The teacher of that class went on to be dean and also head of the entire university's honors program a year or two later, IIRC. So FWIW this seems to have been a hot topic in academia at that time, too (mid-2000's). I think given the global political climate at that time, the years of OIF when accusations of imperialism were being leveled at the US on a daily basis, it was a fairly interesting and relevant course relative to much of the rest of the department.
Using Go (or more recently, Rust) for some parts is a common thing lots of companies have been doing. At my last job we did it with ColdFusion and Go.

CI was omni-present on GitHub in the form of Travis; integrating it in GitHub was kind of a no-brainer, and Kanban boards have been around long before GitLab. It seems more "convergent evolution" than anything else.

> incumbent competitor that remained stale for years before being bought by unlimited money Microsoft.

GitHub already got $200-300 million in revenue before they got bought by Microsoft, roughly equal to GitLab today. I don't think money is really the big factor here (and AFAIK GitHub finances are still independent from Microsoft; they don't "pump money" in it).

I don't know why GitHub was relatively stale before Microsoft bought them. I suspect the reasons are more organisational than finance-related.
The vast majority of that WR in marathon is doing low intensity long runs every day with only one day dedicated to race pace. That still broadly strikes me as primarily low-intensity training.
Running an invisible forum with no engagement didn't even bring them close to the actual problems of running social media. When you're twitter or facebook, you literally have the FBI meeting with you regularly to censor speech.

Democracy is a bit of a prisoner's dilemma.

There will always be people who want to take away your freedom of speech; especially other countries. Any exception to freedom of speech basically can never be weaponized. "Hate Speech" is readily and easily weaponized against your political opponents.

Everyone gets the right to speak or nobody does. Which is what we have right now. I realize where this post shall go.

A democracy where you cannot speak to your political opponents is a democracy doomed to collapse.

I read that book, and as with most other sources of information about endurance training, I found it to be very focused on the situation where people are limited by their recovery budget. I couldn't tease out what the guidance would be for someone who only works out 3-4 hours per week. There would be physiological explanations of the unique value of low-intensity training, and I would think, "Sounds like this applies to everyone," but then there would be an implicit reference to overtraining. Eventually I came to the conclusion that everything in the book assumes that you're training so many hours per week that even if 70% of it is low-intensity, you're still stretching the limit of your ability to recover.

I haven't made an exhaustive search or anything, but I've repeatedly been frustrated by this pervasive assumption when looking for information about endurance training. I guess this makes sense, because even the amateurs I know who love endurance sports work out 10+ hours per week. I just don't love it that much.

I've found one single piece of advice (and again, I haven't made an exhaustive search or anything) in a podcast interview[0] with an expert on and advocate of polarized training for cyclists. In response to a listener question, the expert said that if he only had four hours per week to train, he would "just hammer... and hope for the best," meaning train as intensely as he was able.

I'm a non-native English speaker so I grew up with subtitles, and I still use them today, even though I use the English subs now and not in my native language.

I don't agree with the premise that it has become harder to hear dialogue. In some movies yes, and in some of them that is deliberate. But most of them time I can perfectly hear what they say, but I find that subtitles help me to remember certain details, such as names. It also helps when the talking is going really fast in intense scenes.

Weirdly enough I have experienced audio issues at cinemas where the voices are difficult to hear, but everything else is fine. Watching those same movies at home and it's all good. Probably just an issue at my local cinema though.
> This story is probably BS. Omar influenced Muhammad and had him under his command.

There have been a number of revisionist histories of early Islam that have been floated by serious historians. Has any of them ever cast aspersion on that story, and if so, for what reason? Has any of them made the argument that it was Umar who was the motivating force behind Islam? (using God knows what evidence--seems like if one isn't inclined to accept the basics of the traditional accounts, there isn't a lot to go by period)
If anything it's the other way around - the 1% are going to be OK pretty much no matter what, it's everyone else that this matters for. Right now the US and most of the developed world does not have workers to spare for weird and potentially pointless speculative work of questionable value to society as a whole - they're struggling to find the workforce needed to supply the things ordinary people need and want, including stuff like healthcare. Just pointing at "supply and demand" and calling for pay rises, as I've seen so many do, does not solve this issue unless it causes a shift in workers from doing useless work to more useful work.
It'll be short lived if it is even a thing. Forget bicycles, you're looking at a power loom for the mind. The next industrial revolution is here.

If you need to...

- Mount volumes in your dev container

- Run commands after the container is built

- Pass environment variables from the host to containers

- Specify which containers will be ran in a docker-compose definition and which one will host the vs code server

- Use arbitrary flags in docker run / docker build / docker-compose

You will end up with a Makefile or bash script that roughly looks like a .devcontainer.json file.

Devcontainer files are also neat from an UX pov because new devs can just click on "open remote" and wait. I've been using this feature since 2019 and it did wonders for project onboarding.
I’d guess that vehicle-to-grid will get not get past small-scale trials. Not because of wear-out, but because the vehicles are probably not located at the most ideal locations for the grid operator.
Show HN: Self-hosted RSS to email service with GitHub Actions
By combining a couple of open-source projects, I created a simple, personalised solution for consuming your favourite RSS feeds via email. I built it for myself, but after a few tweaks, I opened up the repository for anyone with a GitHub account to fork or clone. To use it, just configure your own favourite RSS feeds, set up a cron schedule, and provide your own SMTP server.

The email can be fully customised and is made with this great new library: react-email. The project includes a development server, which you can run locally to test any tweaks you want to make to the email template.
Maybe this is just the outside view talking, but it seems like a CEOs biggest function is to be the public face of the company. To take abuse and answer tough questions so the investors don't have to. This requires a fair bit of PR talent, and also the ability to withstand a lot of public hatred. Apparently that's worth a lot of money.
Now that's an interesting idea. Let's see how it will unfold globally. Maybe it will indeed be painless feature.
This is completely accurate. Often done by shifting the reported cost structure to claim transmission is vastly more expensive than generation. You are not doing transmission, they are so you pay them more.
> There's no way any business will handle business logic to a black box.

You mean, a black box like a programmer's brain? An AI backend will get used if it's demonstrably better on any dimension. The current iteration is no doubt a bit of a toy, but don't underestimate it.

It seems incredibly obvious that you could turn this into a real product, where the LLM generates the code once based on a high-level description of a schema and an API, and caches it until the description changes somehow.

GPT can generate thousands of lines of code nearly instantly, and can regenerate it all on the fly whenever you want to make a few tweaks. No more worrying about high-architecture designed to keep complexity understandable for mere humans. No code style guides or best practices. No need to manage team sizes to keep communication overheads small.

Then you train another AI to generate a fuzz test suite to check an API for violations of the API contract. Thousands of tests checking every possible corner case, again generated nearly instantly.

Don't underestimate where this could go. The current version linked here is a limited prototype of what's to come.
It’s shocking, that there are millions of people picking various objects from the boxes every day all over the world. I know, robotics is hard. But I would guess, that is couple orders of magnitude easier than self driving for example. Light is controlled, temperature above freezing point, size of the box known, shape and size with weight as well as weight distribution of the object are known. Why it is not happening?
I use KeepassXC with password + yubikey challenge response. My mental model is that this encrypts my database using my password combined with the yubikey response. With this configuration- it appears that I should be able to put my database anywhere in the open.

Which leads me to my point: If the password manager is properly used then why do we care if the encrypted databases were leaked?
That's $3/month on S3.

My personal instance has been up two months with 12 GB space used, but only 88 MB of that is my stuff; the rest is just the cache of others' posts. That can be fairly aggressively cleared out, and I think Mastodon lets you configure an automatic purging of this data.
Even if each dataset is biased, I’m not still not sure how you derived logarithmic growth from the general notion of bias in data. For instance, assuming the data is biased, perhaps it is biased in the other direction and contains more common patterns compared to the underlying distribution.

This isn't a solution to the search problem but a good option would be to add the ability to search by original index date. Google and DDG have operators for searching by date, but they are limited and seem to be looking for dates declared in the indexed documents, not on an internal date. One advantage to searching by original index date is that it cannot be manipulated by SEO's retroactively, so searches can be crafted to get results from before a time when SEOs started manipulating the topic you are interested in.

If you're a consumer in the UK, and thinking about an EV, consider Octopus Energy's Go tariff: https://octopus.energy/go/. They also offer a salary sacrifice scheme to buy EVs: https://octopusev.com/, because this grid-supplementing storage is part of their offering, I think.

Concerns such as, "will my car be charged in the morning -- or for that emergency hospital run?" are considered, I believe, and you can set things like a "minimum charge" with smart chargers.
In principle, your passwords might be stored as a JSON blob encrypted using a key derived from your master password. In which case that metadata could still be secure. I doubt it though.

Ask HN: How does an OS become aware of memory layout?
I have been learning about Operating Systems the past few months through MIT's XV6 book (RISC-V edition).

One thing that isn't made very clear is how computers in the real world "know" the memory layout for memory mapped i/o (like, which addresses map to which devices in the physical address space).

I have a couple of questions:
1. Whose responsibility is it to define the memory layout (is it the ISA's? The MMU's?)
2. Do kernels know beforehand the layout? Or is it more common for them to discover at runtime?

Thanks

“Quiet quitting” was corporate spin shopped around to gullible journalists. The behavior described was employees doing what they were paid to do but not giving the company freebies.

This is important to understand because it relates to why there are layoffs now: the managerial class hates when normal workers have negotiating clout. Layoffs remove that clout by cooling the job market and making existing employees afraid to leave or ask for market rate pay.

This is important for most HN readers to understand: there’s been a long tech boom where we’ve had above average pay & benefits due to demand. This has lead a lot of us to think we’re part of the upper crust at companies because we’re paid and treated better, and that this is the natural order of things. Few C-level managers agree but they’re definitely hoping we continue to believe it and don’t unionize.
What does unison provide in this strategy. I remember the old Keepass, is KeepassXC the next generation in this?

that really only applies to people with 1-3 email addresses, where heavy re-use means that any breach likely made it public.

for those with an email address per-service, it's not true at all - and even when an email is leaked it is trivial to shut that email down.

in the past the guidance was don't re-use your passwords - I posit that the guidance should now be don't re-use your email addresses.
It might be enlightening if you, as I just did, look up that intersection on your mapping service of choice. "Very complex" it is not.
Nobody has ever claimed a 100% genetic basis of difference. The individual heritability of IQ is .5 to .8 for example

Sub-Saharan diversity is a real thing, eg Bantu, Nilotic, Pygmy and Bushmen are extremely diverse (African Americans are not Pygny or Bushmen so not as diverse)

But if you use cluster analysis on human genomes and ask it to divide humanity into 2 clusters, it divides humans into Sub Saharan Africans and everyone else.

The key is selection not just randomness (most variation does little or nothing) you can't say eg "Africa is the most diverse therefore it will have the best adaptations for altitude" (that would be Tibetans, courtesy of interbreeding with Denisovians)

The number of variants responsible for skin color is actually extremely small. It's why you can have such large variation between siblings.

In contrast yes intelligence is highly polygenic. However, given sufficient sample sizes you can calculate genome wide association scores and work this all out.
