nbernard··on Gravity seems holographic. What does that mean for reality?
Depends on what hypotheses you are willing to accept, but, as far as I know, it is generally accepted by physicists: https://en.wikipedia.org/wiki/Bekenstein_bound
nbernard··on Chinese cargo ship makes inaugural journey, reshaping global trade
I understand Russia (Rosatom) charges a 6 digit toll on this route, but I have not seen hard numbers.
nbernard··on Calibrate Before You Accelerate: Bias Toward Action in a New Role
When I hear "Bias toward action", it reminds me of von Hammerstein's typology:

> I distinguish four types. There are clever, hardworking, stupid, and lazy officers. Usually two characteristics are combined. Some are clever and hardworking; their place is the General Staff. The next ones are stupid and lazy; they make up 90 percent of every army and are suited to routine duties. Anyone who is both clever and lazy is qualified for the highest leadership duties, because he possesses the mental clarity and strength of nerve necessary for difficult decisions. One must beware of anyone who is both stupid and hardworking; he must not be entrusted with any responsibility because he will always only cause damage. [0]

So reframed, TFA argues that one must be "hardworking and clever" instead of "hardworking and stupid".

nbernard··on Everything you do is being recorded
The problem is a Faraday box only attenuates signals. And it usually does not attenuate all frequencies identically.

So your test may seem successful, but the box not be enough closer to a tower, or if your neighbor added a new AP, or if cell phone frequencies changed since you bought and tested it. Moreover, if you have to open and close it often, you have to be careful that the attenuation doesn't degrade.

All that to say that the "Faraday box solution" would mean testing it regularly with professional instruments and all that. It is far simpler and cheaper to ask guests to leave their phones in their cars.

nbernard··on Everything you do is being recorded
> How about a Faraday box, by the door?

Not as easy as one may think. If you put a phone in a generic waterproof metal box (metal junction or biscuit box for instance) and call it with another one, most of the time it will still ring...

nbernard··on Workers Drilling in Romania Broke into a Cave Sealed for 5.5M Years
Indeed. That's one of the reasons why the "Before Present" time scale (that uses 1/1/1950 as the epoch) is sometimes called "Before Physics" (another one being that 1950 is less and less "present", of course)!
nbernard··on Reverse Jevons Paradox
> Jevons paradox happens when the cost of a resource goes down, but the total spend on that resource goes up.

I would argue that is not Jevons paradox but standard supply and demand (and this "reverse Jevons paradox" too). Jevons paradox occurs when a more efficient use of a resource leads to an increase in its use (instead of a decrease as a first order analysis would suggest).

nbernard··on I'm switching my phone from Android to Linux
Just received mine. Sure, the interface is far, far slicker than what is available on the Librem 5, but there are already hints of "you are not really the owner of the device" (for instance default "safety" contacts in the contact app that you cannot delete, the inability to easily use "reverse tethering" (getting Internet by USB through a computer) and so on) that will make me keep the Librem 5, with all its own issues, as my daily driver for the foreseeable future.

(And the Jolla's "hardware privacy switch" feels like a bad joke: yes, the switch is hardware. What it does (if anything) is fully handled in software.)

nbernard··on Writing by hand is good for your brain
> This is actually the biggest reason I own a Remarkable 2/Kindle Scribe, let's me "destroy" the book while also not having to worry about losing my notes.

Well... I'm mostly back to paper after losing most of the notes I had taken on my own Remarkable 2.

nbernard··on Finitude of Knowledge
> I imagine all of collective known knowledge as a sphere Which is finite which is depicted by boundaries or surface of the sphere And the sphere is growing . Uneven growth in all directions 4pi steridian.

Why a sphere and not just a circle or conversely a hyper-sphere in many dimensions? The idea of sphere and growth with 4pi steradian suggests you imply something on the fundamental number of dimensions of knowledge (that may or may not exists).

Regarding the growth of this "sphere": if you consider that a human brain is finite and can hold only a finite quantity of information, then there must be a point where any new concept is too large to fit. Hence, the growth stops somewhere, unless we find a way to go beyond this natural limit (but then, are we still speaking of human beings?).

nbernard··on Why did this journal retract two 1940s papers by Max Planck?
Indeed. When publishing in a scientific journal, you usually (have to) give them an exclusive licence on your article.
nbernard··on Ask HN: Books about Genetic Algorithms
Be aware that genetic algorithms are a type of evolutionary algorithms: Do you actually want to learn about genetic algorithms specifically, or more generally about evolutionary algorithms ?
nbernard··on Linux on Older Hardware: The Complete Revival Guide
Some Linux distributions (Debian for instance, so probably most Debian-based ones too) have sets of legacy drivers for older nvidia cards.
nbernard··on Ask HN: Would you want to know when and how you die?
https://en.wikipedia.org/wiki/Life-Line
nbernard··on Cars collect a startling amount of data about you
At the same time, EU mandates that new cars must have a system able to call help if it detects a crash with the driver not responding... And I suspect most manufacturers will argue that telemetry data are not PIIs until taken to court, so since they have to put a cellular connection anyway, why not use it?
nbernard··on Canvas online again as ShinyHunters threatens to leak schools’ data
Good luck having people forward an email a) with headers and b) in a way that doesn't break the signature...
nbernard··on Acetaminophen vs. ibuprofen
They are common in France, but not in such packages: There are restrictions that prevent you from buying more than than 8g/day (theoretically at least, I don't believe they are strictly applied in practice).
nbernard··on Backblaze has stopped backing up your data
Probably. When available, reader mode can also be activated by clicking the little "page with text" icon on the right of the address bar.
nbernard··on We have a 99% email reputation, but Gmail disagrees
From your PoV maybe. I would be restless knowing that I may be silently losing important emails because they triggered some blackbox filter in such a way that they didn't even end up in my spam box...
nbernard··on Artemis computer running two instances of MS outlook; they can't figure out why
The point is that fetchmail doesn't need an admin once it is configured.
nbernard··on French e, è, é, ê, ë – what's the difference?
> Ë with diaeresis is the easiest case to deal with. The diaeresis (the two dots) signifies that the underlying “e” is pronounced as /ɛ/ (as “e” in “bet”, i.e. the open e), no matter what comes around it, and is used in groups of vowels that would otherwise be pronounced differently.

Yes, but there are other uses. For instance, in "ambiguë", the ë itself is silent but signals that the u before it is pronounced as a standard u. Without the diaeresis, the u itself would be silent but would make the g hard (in French, g before e is soft).

nbernard··on OpenRocket
I believe it is the same project that was discussed here a few days ago: https://news.ycombinator.com/item?id=47385935
nbernard··on $96 3D-printed rocket that recalculates its mid-air trajectory using a $5 sensor
> God, I feel like I am going to be on a list after clicking that link.

It's a poor life that doesn't put you on a few such lists!

nbernard··on The emergence of print-on-demand Amazon paperback books
It does indeed, yet if the review makes it clear that the text of a book is not at fault, that the crappy print on demand edition is the issue, it should not matter too much. It would even give them arguments to ask a few pointed questions to their publishers.

And aggregated over all the books that use print on demand, the editors will notice.

nbernard··on The emergence of print-on-demand Amazon paperback books
> The current solution? Just return the item.

Yes, and write a low stars review explaining the problem. Returns alone don't hurt future sales of identical items.

nbernard··on Innocent woman jailed after being misidentified using AI facial recognition
Good point! It shows that the settlements are far too low and that the victims should get a lot more.

If a few cities/states were to default due to debts coming from such cases, the others would start to take notice...

nbernard··on FontCrafter: Turn your handwriting into a real font
IIRC, it is nerfed out. It is more open core than actual open source, and the paywalled features of the online version are missing.
nbernard··on Ask HN: Are there examples of 3D printing data onto physical surfaces?
Yeah, that's why M-discs were created. Which only displaces the question to "will there still be drives to read them?"...
nbernard··on Major European payment processor can't send email to Google Workspace users
Some (old?) spam filters may be triggered by html only emails.
nbernard··on Song banned from Swedish charts for being AI creation
The humans are neither a race nor conscious. They're humans.
