Thanks for linking to that. Always helpful
for me to do a refresher on the rules once
in a while.

This is a perfect
submission, according to the criteria on
that page. Sometimes an idea might look small on the
surface, but it's just the tip of the iceberg. For example, Leibniz's first demo of binary notation
~250 years ago notation was just about 30
character's long! It would have fit in a smaller tweet than
mine! Would the discovery of binary notation
not be Show HN Material? I actually think you might be able to make the case that the shorter something is, the
more worthy of Show HN it is.

Just to specifically go through a few of the items:

> Show HN is for something you've made that other people can play with.

I made this. It's an idea and you can play
with it in your head. It's actually the ideal solution and solves a decently sized problem that hundreds of
HN posts have talked about struggling with
in the past. I've been working in this area for
over 17 years.

> The project must be something you've worked on personally and which you're around to discuss

Check.

> A Show HN needn't be complicated or look slick. The community is comfortable with work that's at an early stage.

Check.

Also, one for you to keep in mind:

> Be respectful. Anyone sharing work is making a contribution, however modest.
Actually, you don't need another copy of userland. You merely need a dedicated space for the jailed OS (assuming we're talking OS-style jails, not process-style ones) to write the things OS writes to (devices, logs, etc.). You could get away with null mounting your host filesystem and then mounting writeable space on top of it. Once I've had read-only mounts for my jails, for funsies.

Not here in Iceland we have more electricity than we have use for, it goes to bitcoin mining or it goes to aluminum smelting. No connection to the outside world grid.
> I believe using such escalating fees would just favor the big companies who can stay ahead of the curve.

But that’s fine. If a company can rake in so much money off of one product it’s still providing an obscene amount of value.
I don't believe it's a joke. It still might be a deliberate lie (a random twit is not a real source of knowledge), but so far this is consistent with what we already know. See https://news.ycombinator.com/item?id=25769730
There were multiple photos of a man wearing a shirt that said "6MWE" which stands for "Six Million Wasn't Enough", a direct reference to the holocaust. Are you saying you don't believe that sentiment is in line with Nazis? Or do you not believe that this shirt was on display there?

https://www.jta.org/2021/01/11/united-states/a-photo-of-an-a...

Edit: And this is one example, if you are truly in the dark about these symbols and what not being on display more examples can be provided but I really would like to know if you've seen this and what you think.
Is there anything like docker layers for jails? Or.. at least like a tar-overlay and any symbolic links needed?
The outskirts of Beijing were still pretty grim, by US standards.

The issue with command economies has always been the producers have no incentive to succeed, hence productivity is atrocious.

But has anyone ever tried something like a fixed-price contract for standardized essentials, on a national scale?
I’m assuming that this one wasn’t just a one man band, doing their own QA and making their own engineering samples.

Looks like the author updated their hours estimate.
Yeah. The $99/year is big enough to pretty much block out all hobby devs and open-source projects, so what's left are generally commercial and closed-source. Apple says that they do their own vetting of extensions, but I don't trust Apple to prevent extensions from reading my browsing history, especially considering spyware extensions like Honey are served on the App Store without warning.
On rotating media, I assume copies=n might improve performance... By multiple copies of a piece of data existing, whichever piece of data is closest to the read head can be read. Rotational delays on a 7200 RPM risk are about 10 milliseconds, so if you can halve that by picking a closer copy of the data, you'll get your data back quicker!

All this depends on the filesystem issuing reads for all the copies, the drive firmware correctly deciding which to read first, and then the OS being able to cancel the reads of the other copies.

I kinda doubt all the above logic is implemented and bug free... Which is sad :-(
I'd assume at this point people want it as a hedge against inflation tbh. So people want it so their fiat money won't decrease in value is more accurate.
Can I add another gotcha - if you have a failed device in zfs and you can't import the pool anymore, don't think you can walk the drive and put the blocks back together manually.

You can do this in FAT and mostly in NTFS and UFS - especially if your drive is defragmented.

But the complicated data structures of ZFS makes this really hard if not close to impossible - there are tools and ways of using ZFS code to help you do this, but they are exceedingly hard to use.

Source: took me 52 hours to retrieve a 16k file from a failed device. Granted it would take me less time now, but I now think of devices the have failed as if they has completely disappeared from our universe.
It could be on any platform. Discord would serve just as well. Facebook is just the common denominator everyone currently uses.
People who use Safari aren't the same kind of people that use browser extensions.
But it cannot always remain a preprint; at some point the author must decide on the definitive version and publish it; citing a preprint is also problematic if it is in fact a "moving target"; preprints, however, have a decisive advantage: one has published more quickly and can make subsequent corrections.

EDIT: Preprints are actually not a replacement, but essentially loosen the submission deadline and increase the number of (potential) reviewers. But even with this, many disadvantages you criticise still exist; the public reviewers not appointed by the publisher can also be wrong, and the outcry of indignation can be so loud that the author's superiors enforce a withdrawal of the publication.
A lot!

Interesting way of looking at this: monopolies stifle markets and hurt consumers. But consumers of the ad market are not the end-users, they're the companies buying ads. Therefore, by strangling the market, it is actually possible for Google to be helping people for whom that market is a bad thing (which is most of us).
Have you got any non-trivial examples/plans of that happening beyond btc mining speeding up the existing "we need to solve this so fewer people die" process?
> If you’re just giving it away as a free disposal service, then sure it doesn’t matter.

For my wife and me it's not just free disposal (I can handle my free disposal by going downstairs and dumping it by the side of the trash container). It's about ensuring a working item doesn't get trashed, but will continue being useful for someone else.

In all my wife's giveaways, there's one or two people out there who are regular, repeat "customers". But we can't tell whether they're hoarders, or whether they just happen to need all the stuff they get from us, or whether they pass that stuff on to their family and friends. Or hell, maybe they resell it. Doesn't matter, as long as we're somewhat confident someone will make use of it - because that's someone who saved their money, and that's one less item being bought.
DuckDuckGo – Privacy, Simplified
I think 20 years might be a reasonable amount of time for hardware, which requires a heavy outlay in money to produce and which does not have almost zero cost to replicate, but not for software which can generally be copied for nothing and does not cost much to produce.
Sorry if it’s not for you. I am rather frustrated by music teachers often even not knowing or being interested in the first principle of what they’re teaching, and think I was lucky to have a retired physics teacher teach me music. It is all about fractions, so why shy away from it? Many teachers can tell me about intervals and scales, but not answer why those sounds fit together - like how a 5th is 1.5x the frequency of the tonic. That’s no better than just memorising chords on a piano. I want to see the beauty in its essence!

Good thing this world can accommodate more than one style of learning! Take care
There was a post recently about building a home fileserver that mentioned a file system that did this - it was just a layer on top of existing disks and file systems and sorted files by directory (and could send a file to multiple drives if so desired).

I can’t find it now but it was an interesting website.
> even earthly nuclear energy reserves may become strained on a thousand year time horizon

No, they won't. Even if we restrict to just fission power, on a thousand year time horizon we can expect thorium reactors and extraction of uranium from seawater, which multiplies the available energy by a factor of at least a thousand.

Furthermore, on that time horizon we can expect fusion to be available, and deuterium from seawater multiplies the available energy by a factor of about a billion.

Not to mention that on a thousand year time horizon, we should be making full use of the available solar energy in Earth's vicinity by means of orbital power stations, in which case we won't even need any other energy source on that time horizon except for specialized uses like fast spacecraft.

> On a thousand year time horizon it's entirely plausible that maintaining a purely renewable economy makes the production of certain materials impractically expensive

And it also makes it practically certain that any material that's that expensive to produce won't be needed anyway, since cheaper substitutes will be found.

"Limited resources" by itself simply doesn't strike me as a plausible Great Filter.
Firearms industry had this as well. Smith & Wesson for the longest time fought tooth and nail to be the only revolver manufacturer in the late 1800s and early 1900s.
Sounds like we’re on the same page? All I’m trying to say is that gold vs. Bitcoin is not an apples-to-apples comparison.
It is somewhat natural to just refer to 802.X standards as 802.X when implementing them as that is the correct name of the standard and you need to read most of it in order to implement it. If you want to talk about distinct added features it makes sense to use the name of TG (ie. 802.[number][letter]) that drafted the specification of said feature, but it is mostly only an handy shorthand.
Yes we need (again) an inversion of control. At first advertising links only tracked origin (website), so announcers could target right website to put links on it. But soon advertisers realized you could gain more granular information in using more active technology like cookies, gifs, flash, etc. So they began tracking users and their journey through all websites with all privacy problems it entails.
I think in terms of privacy the only level acceptable is the one you have to deliberately have to engage with to start "tracking" (that means advertising content must be displayed alongside publisher content and not personalized nor tracked through advertising company if the user hasn't engaged with).

I also think that marketing/advertising is bad since it distorts value perception but i remain pragmatic and we can't ban all advertising that easily.

I agree there isn't much benefit to a civilization of creating a colony too far away to be able to effectively communicate with (apart from the philosophical benefits of 'not putting all your eggs in one basket'). The isolation might be very attractive to some colonists though. Just as the pilgrim fathers sailed to america to escape religious persecution and start a new society. Whether a group smaller than a state or civilization would have enough resources to do this is another matter.
The expected workflow is to launch it once — say, when you come to work — and have it running for the rest of the day. The startup time is completely neglible if you do that. And well, running GUI apps from a terminal is likely to flood that terminal with logs (which is why I launch them outside of terminals).
> It's questionable if its good economic use of these people's time though.

It may not be, but the problem usually is that the market can't make a better use of those people's time. I don't think many people would work such high effort, low pay tasks if they could actually get a better job.
Well plugging an iPhone 11 into the wall with the included cable would be 5W and the phone itself only supports up to 18W. So yeah plugging it into the wall will be super slow too.

So yes some people will buy a USB C to lightning cable for their older iPhone and a better wall adapter but most people will just use the included charger.

If you own some resources, under what circumstances should someone else be able to tell you how to allocate/use them?

It's perfectly valid to say that governments should make laws or economic policies to prevent negative externalities like pollution, but that is begging the question of what activity is causing the pollution.

If your bitcoin mining rig is in an area that is powered by a coal power station, then you are indirectly increasing CO2 pollution, but coal that is burnt to supply other customers with power is no less polluting.

Therefore it doesn't seem equitable to single out just one user of the electricity. It is even more inequitable to punish bitcoin miners that use otherwise-curtailed renewable energy for the externalities of non-renewably powered miners.
Fox News has science articles? That is more surprising to me than the science reported.
This may become part of the ePrivacy Regulation that is in discussion within the EU. Quoting from the description[1] of the proposed regulation:

"Simpler rules on cookies: the cookie provision, which has resulted in an overload of consent requests for internet users, will be streamlined. The new rule will be more user-friendly as browser settings will provide for an easy way to accept or refuse tracking cookies and other identifiers. The proposal also clarifies that no consent is needed for non-privacy intrusive cookies improving internet experience (e.g. to remember shopping cart history) or cookies used by a website to count the number of visitors."

There has been lobbying and back-and-forth on this particular topic in the regulation, and I don't know the current status of it.

Galactic's mission is essentially unrelated to space, beyond providing a short peek at it. Sending a plane up to the edge of space for a brief period with passengers aboard barely overlaps what's needed to put anything in orbit. It makes sense that they'd be different companies.
As evidenced by the hypergrowth of EVs in Europe over the last few quarters, it is government regulation which is shifting the industry to EVs, not Tesla. I agree that Tesla’s strategy is to boil the ocean with investor’s money.
All of these posts are false equivalency until we are willing to compare energy usages of other "frivolous" uses.

* movie viewing
* 2.0 phone apps no one wants
* the entire payments industry
* banking energy consumption with all facets factored in (human resources, commuting, logistics)

He's writing this in Borland C++. If my memory serves me correctly, there wasn't even a widely available STL implementation for this compiler, let alone standard header names, standard containers, lambdas, <algorithm>, <numeric>, hardware abstraction libraries, etc. etc. etc. The title is verbatim "I wrote a Raytracer for DOS, 16 VGA colors."

Everything you take for granted today was bought and paid for with what people learned yesterday. You're judging technology that's likely close to 25 years old and the person using it by today's standards.
It's not "buy nothing", but there's a forum local to my area where a sub forum is basically "curb pickup" and people post anything they want to give away. If someone else wants it, you put it on the curb in the time agreed.
Same here. In the past 18 months, we've saved something between $1000 to $2000 on baby stuff alone. And we do our best to "pay it forward", giving out everything that we don't need on these local groups. It is indeed the nicest what we ever got from Facebook.
It disincentivizes looking at the site 24/7 to be the first claimer.

You see similar proposals for stock markets to process all orders that come in within one second in arbitrary order, to disincentivize the insanely expensive chase for nanoseconds in high speed trading.
While y'all will likely hate it, support costs can easily eat up any profits that you might have had from a reasonably priced app.

Selling for $1 on the ios app store is only financially viable for me the developer if everything is standardized so that I never have to deal with any customer-specific manual work. That's why the ability to block ios app execution on Mac is crucially important to keep things profitable for developers.

I usually hate Apple for locking things down, but in this case I believe they had to do it, or else risk sacrificing many ios developers.
My experience has been _exactly the opposite_.

You don't need to do anywhere as much validation if you just assemble hard macros, and other pre-validated circuitry.

It's completely different to make an SoC from scratch on RTL level, vs what I was talking above.

100% Untrue. I use many extensions in Safari just like I use to in Chrome, my needs for customization are the same regardless the browser I use, but like many choose Safari for his performance, privacy ui, among other benefits. Find it very frustrating that many of the big products don't have Safari extensions. Often when I email there tech support they give a reason why, and then I try to explain there are referring to how extensions worked before, rather than how Safari extensions work now. So imagine a lot of companies don't know about the changes, or think they don't need to because they don't have enough people asking for them, but people probably did ask for them but were told it was not possible before, so they stopped asking.

Hoarders love regular CL too. I sold a huge and somewhat expensive 21" CRT monitor on CL and the buyer asked me to deliver it. When I got to his door, he cracked it open and said just leave the monitor in the hall. The apartment was completely jammed with stuff.

Making people who need your stuff pay you in stories or "gratitude" does not appeal to me anyway. Even if I have a $5 item to give away and someone just flips it for profit, that is time they spent and I did not, so the item is still gone from my home and someone who actually wants it gets it. The fact that one other person also benefitted doesn't bother me.
No. VCs back an extremely limited number of companies. Most startups target such a limited market (geographic or otherwise) that the VC-backed companies don't bother to compete in such a small market.
Nice, this is great. I was recently looking for some QuantLib bindings for Rust and its not really there yet.

There's a great book called Implementing QuantLib by Fabio Ballabio that is a really nice introduction to QuantLib for those that are interesting. It is really nice, has lots of term structure data structures built in and some datetime abstractions useful for pricing/risk calcs, and supports lots of financial instruments, like CDS, vanilla/exotic options, bond calculations. Just wonderful.
If you're interested to read a primer on avionics and control systems, yes.

If you just want to know whether it's safe to get on a 737 Max, no. For that, you'd need a white box analysis of the software, access to the change log, and, ultimately, millions of miles in the air waiting to see what happens.
I totally agree. But that probably won’t involve programmatic/traditional advertising. It will probably involve first party ads. Which I am definitely in favor of!
