I don't know, seems kind of a stretch to say crypto is decentralized because everybody uses the same protocol. Is the IP protocol centralized too by that standard?

On the other side yeah, most of the goals of decentralization could be achieved by looking at things like the Bittorrent / Pirate / Scihub projects which have been delivering content consistently in a distributed way for decades.

A blockchain is only necessary if you need an immutable history for some reason for a specific part of a process that you want to implement, but every other part of the process can live apart and work without any blockchain tech.

Yes, this is rather unfortunate. There are also some more "portmaster" things around, which were partly mentioned in an older HN thread.

We thought about a rebrand, but it's just way to expensive right now, as we are still bootstrapping.

I also don't think that there is an immediate issue, as both application domains and presence on operating systems don't interfere.
If you think otherwise, please share your thoughts!
I can't say I have much of an idea of what goes on in a cockpit but presumably not everything is related to something a computer knows, or can change. Clean windscreens, functioning levers, coffee cup filled ;-)

Also having to poke the computer also helps check that the computer isn't obviously broken.
That's such an interesting thought experiment!

Who would raise the artificial kids? Who would pay for it in the first place?

Maybe government. Or scarier some company.

It would be awesome if we could fully support children and education. It would be gross if the only way to do that was capitalistic incentives.

Maybe that's a sick sci-fi startup idea to pitch (more like write a book about).

Raise kids from scratch, long term 50 year roi horizon returned from the increased earning potential from having raised the kids and educated them better! I doubt VC money would go for something unless you could speed up development to get your unicorn in 5 years lol

Joking aside it seems to me the answer is way simpler and doesn't require magic tech. We still have working bodies. We just have to support them with free childcare, great education, healthcare, and other social support for parents. But we can't seem to get enough votes for that. Immigration is an easy solution too but same thing...

This applies to most catastrophic failures, not just in aviation but in any other place that puts reasonable effort into preventing them. Usually there are plenty of safeguards, which means that most of the times, when something goes wrong, one of the safeguards prevents a catastrophic outcome and you don't hear about it.

But when you do hear about it (due to the catastrophic outcome or a very near miss), it'll usually be a tale of many mistakes, very egregious misbehavior, multiple failures etc. - because it generally has to be to cause a bad outcome or even get close to it.

Keep in mind that despite this, nothing seriously bad actually happened here. It was a near miss that needs to be addressed, of course, but nobody died, there likely was no serious equipment damage, etc. Ultimately, the system worked.
Because we have specific environmental problems right now, that are quite serious and worth focusing on?

You do this stuff because you want to accomplish something. If animals go extinct, that is obviously unfortunate, but it pales in comparison to the prospect that we do so.

The EU isn't trying to accomplish some type of perfect environmental justice, they're trying to keep the world habitable.
1. Not wearing seatbelts won't render your car inoperative. (At least in the older cars I know. Maybe it already will...)

2. You can become participant of an accident even if you are an attentive, careful driver, through no fault of your own. But you cannot accidentally drink and drive. People who do that act deliberately criminally. I admit that this is just my opinion, but we shouldn't treat everyone as a potential reckless criminal by law. This kind of insulting paranoia coupled with governmental power breeds nightmares in the long run.
(Not grandparent commenter) I think you're usually right but I doubt it makes a difference at the scale of 2-5 objects created in a test case. The big game changers IME are in-memory dbs (SQLite) or parallel execution of tests.

This idea of "transaction rollback in test teardown because performance" has a life of its own. The recommended base class for django unit tests (informally recommended, via code comments, not actual docs) uses transaction rollbacks instead of table truncation [0].

On top of this, I think, db truncation gets mixed up with table truncation sometimes too. For example, from OP:

> The time taken to clean the database is usually proportional to the number of tables

... only if you're truncating the whole db and re-initializing the schema, no?

And people sometimes actually do clear the whole db between tests! One unfortunate reason being functionally necessary data migrations that are mixed up with schema-producing migrations, meaning truncating tables doesn't take you back to "zero".

Web3 is a marketing buzz word and nothing more. You can have a decentralized app but it is still probably going through at least one centralized gateway. Until everyone is running IPFS or something similar and people are going to want to host multiple copies like a torrent, then you'll be stuck paying for and hosting the only reliable copy. You're also going to have a lot of people building some censorship control to prevent users from distributing illegal content. Otherwise that first use for Web3 would be pirated content.
I think this is a pretty weak article regarding web3. The author wants to claim Ethereum or Bitcoin are more centralized than HTTP, but that isn't a valid comparison. Anyone can spin up their own blockchain exactly in the same fashion of spinning up their own webserver. It's more comparable to something like AWS or Discord or Twitter. Now, I would still say the majority of all things developed on the blockchain are very centralized, from DAOs to NFTs to dApps. And I definitely agree that it's because they're mostly all cash grabs. But the articles being published every day criticizing the web3 world recently have been pretty terrible imo.
To be clear they imported already ground bark - which is a red powder - which prompted customs to do a drug testing on it - which must have come back positive for DMT.

If you're importing actual bark, straight off a tree, I doubt customs would ground it up and do a drug test on it.

The Portmaster actually handles DNS itself and will show you DNS queries in the UI. (Currently, only showing DNS queries that were _not_ served from cache.)

Also, Portmaster actually has it's own kernel module in Windows and sees more than Glasswire.

Portmaster sends queries over DNS-over-TLS to protect them and has (very) basic protection against data tunnels.
Because then Russian gas investments could get EU funding, that's why. Like a Russian owned gas terminal on German soil, to be more precise. That would actually take funding from nuclear or renewables and into fuelling another country's geopolitical ambitions.

As for the VSCode extension, do you have telemetry disabled in Code globally? The Red Hat extensions are supposed to respect that preference for any telemetry they send. If you're seeing otherwise, please file a bug if you can.
Yes, very likely, although there's no AI involved and are the humans who are digging their own grave. I can easily picture a future in which 50% of the space available on the planet is allocated for energy production plants, the other 50% for mining farms, and there will be essentially only jobs related to these two activities available, just like using every resource to make paperclips.

C++ has gone down a different path, and reasonable one if I can say so myself.

Bjarne Stroupstrup said:

> I don't like garbage. I don't like littering. My ideal is to eliminate the need for a garbage collector by not producing any garbage. That is now possible.

And indeed, with modern C++ idioms you can avoid leaks at the static analysis level, avoid buffer overflows by simply not passing raw pointers around, etc. So no borrow checker / garbage collector necessary. For a little more elaboration on this point, see:

Who are all of these people who will be hurt by it?

There's nothing interesting (e.g. terrorism, bombs) you can do with nuclear waste, and it's not especially poisonous.

If you just loaded it up in barrels and dropped it at the bottom of the ocean, what's the worst that could happen?

Sure, some fish would die, but where are the millions of deaths?
Ok, now I understand more. I think local-first and single-user mode is easy enough with the tooling we have right now (there are hooks, FS adapters that are almost plug-n-play). The trickiest part is still resolving conflicts/modifications across many sessions that multiple users have across time and lost sync periods.

Depends how you deploy it. Python can import a file located anywhere you want, either by changing PYTHONPATH or using importlib. And vice versa an xml-config file might be placed in the repo and going through code review.

Code review for config changes is a good practice in either case, see gitops and config as code.
Yeah, I was just looking at their code. It's similarly super heavy on SIMD processing, which would significantly impact the cost of the removed branches - it looks like the masochists supported escape characters. I would be interested in knowing whether they do have any benchmarks to validate the removal of error handling, etc
The earliest IFR's were always around 0.3%, and nothing much changed since. Officially they inflated the numbers with tricks by factor 10 (ie reporting only the CFR). Statisticians were furious.

Severity changed drastically, with Delta suddenly targeting young people and long COVID. But people got vaccinated, IFR stayed low. Now severity is swinging down with Omicron.
They don’t even support FreeBSD. Its like saying United chemicals had name collision with United Airlines.
And as we just learned, people make mistakes or skip steps when following those, so maybe the button would be better.
The main issue with "Web3" is that it moves records of transactions from many private places to one public place. Sure this one place may not be controlled by a single entity, but it facilitates tracking at an unprecedented level.

Cryptocurrencies are the ultimate example of this and are an absolute boon to tax collectors, forensic accountants and fraudsters. In our current economy financial transactions are recorded in millions of individual ledgers that are kept private, or in the case of cash transactions are often not recorded at all, or are not linked to an individual. There is no central ledger.

With crypto currencies however you can not only see all transactions but also trace them back to individual users as long as you can link a wallet to a person. This is a massive increase in centralisation yet discussion of whether this is a good idea seems to be entirely missing. The notion that centralising transactions in one place is somehow an example of decentralisation just seems mad.

> How you get to this level of incompetence flying a 777 is far beyond my understanding.

I don't fly, but what I hear from my commercial pilot friends is that many carriers are emphasizing pilots to run on auto-everything so their actual fly-the-plane skills deteriorate. And much worse, the newer generation of pilots never acquired those skills to begin with. due to relying on automation.
> What led us to climate change is going for short-term benefit and leaving the problems to the future. We shouldn't repeat that mistake even though we'll be long gone by the time the problems come to light.

That's how anything works, though. You replace the giant bleeding wound with a bandaid, and then you take it off and there's a scab, and then the scab goes away and you have a scar. It's always about replacing something with a lesser problem. For the past few years people have been trying to replace fossils with imaginary clean power, and it hasn't exactly gone great.
There’s not that much radiation in this water. None of those concerns would apply. They could literally just dump it into the ocean without measurable effect, which is the plan of record.
OK, let us run around this experiment a bit.

Given how specialization works in other areas of life, I would expect "professional parents" to emerge, adopting 5-10 artificial kids over their lifetime. Possibly even more. That could actually be a reasonable job for people who are otherwise less qualified.

In more authoritarian countries, I would expect government-run boarding schools to emerge, preparing boys for future careers in military or the Party, girls ... well, that would depend on local culture, probably.

"Joking aside it seems to me the answer is way simpler and doesn't require magic tech. We still have working bodies."

If it were so simple, some countries would be able to solve it. I would, on the other hand, say, that it is as "simple" as solving the obesity crisis: a problem that looks straightforward from a distance, but turns into a maze of nightmarish "devil's details" up close.

We do not really have working bodies. Peak fertility is in late teenage years and early twenties, but societies which highly value education must shift childbearing to much later age. And after 30, a lot of people who want to have kids are no longer capable to do so without medical help, and this process is so tedious and stressful that you will wind up with smaller families than wished for.

Already about 5 per cent of kids are born out of IVF, which indicates that the cohort of people struggling with fertility is significant.
A couple of years ago one acquaintance of mine, who works at a company making aviation simulators, bought some flight manual for US fighter jet on Ebay.... And when he travelled to Georgia (near the Black sea one), he was detained and deported to the US and has spent a year in prison there on espionage charges.

He was released after great efforts by many people and is forever banned entry to the US. So I wouldn't touch anything 'secret' and 'military' even with a 2 meter pole.
Agreed. The one dollar-one vote concept is fundamentally flawed, but has become the main model for crypto community governance. There aren’t a lot of viable alternatives, especially as there is no concept of a person, just free, infinite wallets and limited coins. As such, the interests of the wealthiest steer the entire community, and a bad actor could derail a project with malevolent use of voting powers. Democracy is messy at best, but where there are no ‘demos’ its nigh impossible.
> If animals go extinct, that is obviously unfortunate, but it pales in comparison to the prospect that we do so.

I agree with the global sentiment of your comment, but let's not forget that animal extinction is 1/ well on its way and 2/ a direct precursor of human extinction.
Well, the main challenge is that you can take a capability and limit it before passing it on. For example, take the FileSystem capability and wrap it in a new object that only allows access to a specific directory.

Otherwise, you could probably use OAuth!

Now, Firefly makes it possible to limit capabilities with arbitrary code. But suppose you instead had a declarative format for limiting capabilities.

Then you could probably represent capabilities like this:

{
"system": "FileSystem",
"publicKey": "...",
"parent": "...",
"limitation": {
"path": "/foo/bar"
}
}

The publicKey is the public key of the system in question. The system should probably be a URI.

The parent is the capability that was limited, encrypted with the public key, so that only the system in question can decrypt it. This allows the system to verify the capability, while not leaking the parent capability to anybody else.

The limitation is a system-specific declarative limitation, and must be at least as strict as the parent capability.

How does that sound?
Along with a couple of others (this [1] being an example), thanks for responding. I read paganel's follow up post [2] and was flabbergasted at how out of touch he sounded. The shock is the main reason why I chose not to respond myself this morning. You and the others gave a far more eloquent explanation than the one I would have given.

I will say this, though: just because paganel considered Bong Joon-ho's 2003 film Memories of Murder to be his best work doesn't mean that Parasite winning the Oscar for Best Picture in 2020 meant absolutely nothing in terms of South Korea's state of its cinema scene. If anything, it's even more indicative of South Korean cinema scene's stock rising in the global stage in recent years. To put it in Civilization terms (which I'm sure he won't understand due to his dismissive outlook of video games), South Korea's going for the cultural victory. Soft power really is a thing!

So for any kind of emergency care they are not allowed to "gotcha" with out of network providers at in network hospitals, this has always been the case.

Currently, we just match the IP address to all resolved IPs of all domains and pick the most recent one. (The Portmaster handles DNS via DNS-over-TLS.)

With TLS1.3, the SNI will be encrypted, so this information will be "gone" for us anyway.
Hello HN,

My collaborator and I want to help traditional artists enter the NFT space by creating compelling digital/mixed-reality experiences surrounding their art (yes, bringing it into the metaverse!), and by building supportive tooling for distribution. We are currently in talks with some amazing artists and would love to find developers/researchers/3D artists to help bring their ideas to life. I'm a painter myself, and have extensive experience developing with 3D technologies/AR/VR incl at FAANG/Pixar/etc.

If you think you'd be interested in working together, please reach out (email in profile). We are looking for:

1) 3D,2D animators, visual effects artists

2) Blockchain and smart contract developer/advisor

3) Full-stack, Backend/Frontend engineer

Looking forward to connecting and making some magic!
Ask HN: Do anti-C19 foggers do any good or is this performance?
Lots of imagery on TV shows handheld foggers misting public spaces. I am confident this stuff works for mosquito borne disease, all it has to do is stop hatching of larvae. It appears popular in Asia, south America, Africa, India. I am trying not to assume this is bogus populism.

But, do these mister units actually do anything useful against an aerosol dispersed disease? It feels from here behind the TV set its performative hygiene theatre, and does nothing of substance. Because of mosquito control they have the devices, and they can fog bleach, or TCE or something (that would be terrible)

Or, are "fomites" still a real concern?

UV was said to be used to "sterilise" aircraft interiors. I would probably ask the same question: does it do anything useful?

Web3 is more of a problem soup, I don't think it's accurate to say there's any one specific "main" problematic aspect of it. The whole ecosystem is one terrible idea built on another in the name of achieving a worse version of what we already have.
All very high numbers. The key to solving climate change isn't to do as before, just slightly more efficient. Electric cars won't solve anything, especially not if they are indirectly powered by fossil fuels.

Make cities walkable, bikeable and public transportable. That will have far bigger impact than people buying new electric cars.
You can't compare the two.

There is tons of irrefutable evidence of an ethnic genocide and internment of minimally thousands and thousands, likely millions over the course of time.
