nbernard··on Ask HN: Books or Paper which helped you develop reasoning skills
I found Rational Choice in an Uncertain World: The Psychology of Judgment and Decision Making, by Hastie & Dawes, useful.
nbernard··on Is true free will possible?
True free will? No. Agency? Yes.

(Proof left as an exercise to the reader).

nbernard··on Ask HN: Hands-On Robotics Book/Course
I don't have a reference to recommend but, considering your goals, you should probably search for stuff on the ROS2 suite [0].

nbernard··on Ask HN: What hair on fire problem are you willing to pay for right now?
> Full linux system on phone, available as a desktop experience through hdmi out.

Have you considered the Librem 5 ( https://puri.sm/products/librem-5/ )? PureOS is a Debian-based Linux.

nbernard··on What the damaged Svalbard cable looked like
There is still some witchcraft. Look up "optical pumping amplifier" for instance.
nbernard··on Dressmaking CAD
Not exactly CAD, but Valentina deserves a mention too: https://smart-pattern.com.ua/en/valentina/about/
nbernard··on Segal's Law
Moreover a man with two watches takes the average and gets closer to knowing what time it actually is...
nbernard··on Cultivating minds: The psychological consequences of rice versus wheat farming
According to Braudel (in Civilization and Capitalism, 15th-18th Century, vol. 1), without irrigation rice farming depletes the soil much, much more than wheat. If I remember correctly, he states that if one waits for natural soil regeneration (fallowing and/or crop rotation) wheat can be grown at the same place every 2 to 3 years, whereas for rice it is only every 10 to 30 years.
nbernard··on Ask HN: What new laptop would you get?
In my experience, hardware-related issues mostly happens with stuff that was just released. If you don't mind waiting a few months before ordering, there are usually few problems.

As for UI inconsistencies, I believe they depend a lot on your GUI of choice.

nbernard··on Child pornography on sale from hacked Hikvision cameras using Hik-Connect app
Among the cheap USB webcams, any model you would recommend ?
nbernard··on French Assembly to allow remote police surveillance via phone cameras and mics
In France, the ID card is free. Some other forms of ID (passport, ...) are not.
nbernard··on How to ramp up a factory consuming a lot of energy?
Depending on your supply (for instance in an old house), the printer current consumption can cause a voltage drop on nearby circuits, and this voltage drop can in turn trigger the UPS.
nbernard··on Top Talent, Elite Colleges, and Migration: The IITs
You took the wrong column (the amount to be repaid is €31,000) but your point remains valid.

(Moreover, it is often paid by the employer who wants to recruit a student just after graduation.)

nbernard··on Buy well, buy once
On the other hand, you risk considering a whole tool class as not very useful, when actually it is just that the one you own is crap...
nbernard··on Reduce vs. Fold in Common Lisp
Interesting. Do you know if that is due to constraints coming from ABCL running on a JVM, or is it an arbitrary choice ? (By contrast, SBCL on a x86_64 laptop returns 4611686018427387903...)
nbernard··on The Perils of Niching Down
There is more or less the same issue in academia. Once (hyper)-specialized on some micro-topic, it becomes quite hard (due to workload and pressure to publish) to switch to something else.
nbernard··on Librem 5 availability lead time quietly reduced from 52 to 20 weeks
> the [N9] or its software was so slow it was almost unusable. If I had paid full price for mine I would have been pissed.

Maybe you should have paid full price... ;) I believe the one you got had some defect.

I used a N9 (daily driver) for about 10 years (until I got a L5, actually...), and it wasn't especially slow (OK, the storage was slow for writes). Things started getting worse and worse due to the lack of SW updates (so no support for newer TLS versions for instance), but that is another story.

nbernard··on System D
Exactly. "Improvise, adapt, and overcome" could be a definition of "Système D".
nbernard··on Can you buy the same ticket at a lower price if you buy it from another country?
Maybe. According to [0], the price of an airplane ticket sold in France is 60% taxes...

nbernard··on Ask HN: Why do many CS graduates lack foundational knowledge?
> There is no such thing as computers without programming.

But there is computer science not applied to computers: Operations research for instance is basically a branch of CS: it is not about programming and it has applications in business, logistics, etc.

nbernard··on Using Super Glue
> SG tubes are basically disposable once opened, since they'll be useless when they glue themselves shut or crust up.

You can greatly extend their lifetime by storing them in the freezer. The metal ones then die by leaking once you have used them a few times, but the plastic ones can be used for years if needed.

nbernard··on Ask HN: Why are PDFs still heavily used?
Not really. Even Word for Windows and Word for Mac don't always render them identically, and in Office 365 it may be something else! And when you add LibreOffice Writer and the like into the equation, all bets are off.
nbernard··on Ao486_MiSTer: i486 core for the MiSTer FPGA gaming system
For those who have not heard of the "MiSTer FPGA gaming system" before:

"MiSTer is an open project that aims to recreate various classic computers, game consoles and arcade machines, using modern hardware. It allows software and game images to run as they would on original hardware, using peripherals such as mice, keyboards, joysticks and other game controllers.

MiSTer utilizes an FPGA board called the 'DE10-Nano', which connects to your TV or monitor via HDMI video out. It can additionally be expanded with various add-ons (such as a USB hub, SDRAM, audio and VGA out)."

nbernard··on Maxima: A computer algebra system written in Common Lisp
Do you have any reference/tutorial on how to do this?
nbernard··on Fulcrum: an ergo-mechanical split keyboard with extra thumb functionality
AFAIK, the only difference (for the UHK keyboard, at least) is that, on the ISO layout, the left-shift key is narrower, in order to make space for an extra key. This is visible for instance if you compare their US (ANSI) and UK (ISO) layout.
nbernard··on Fulcrum: an ergo-mechanical split keyboard with extra thumb functionality
Depends on what you put under "ergonomic", but you could take a look at the Ultimate Hacking keyboard: https://ultimatehackingkeyboard.com/ (split, ISO layout & mechanical switches, not wireless however).
nbernard··on Best Calculator for a Nerdy Child
If money is not a problem, have you considered getting both?

I cannot speak for the calculators currently on the market, but over the years I had both a TI-92+ and a HP-50g: I liked both and for some things I preferred the TI, for others the HP...

nbernard··on Ask HN: What is the best thing you read in 2022?
If you like old movies, don't miss the 1959 adaptation!
nbernard··on The sad story of Heisenberg's doctoral oral exam (1998)
I'm not sure about unusual or not, but I believe it was (then and there) possible to start a doctorate right after graduating from high-school (if I remember correctly from a biography of J. von Neumann).
nbernard··on Ask HN: Why does EasyPost constantly advertise that they're hiring?
I don't remember either of those two, but I see GenerallyIntelligent ones very (too) often...
