This is the question I see way too few people asking: how do we want end-game capitalism to look. Should it be Banks' "The Culture", or should it be neo-feudal with the populace at large acting as serf to capital.

Without discussing the vision, discussing the strategy becomes sort of meaningless.

(Edit: typo)

Fjällräven is a very well-established Swedish brand that makes exactly this, and even have their own brand of wax. As far as I know, none of their products have any synthetic membranes.

Here in Denmark, "Fjällräven" is a household name to the point that it can be used to refer to their small backpack model.

In my experience, the whole `PyO3`-project is a rare gem in language integrations since the developers appear to have an intricate understanding of the ecosystems on both side of the integration.

The python parts are pythonic and the rust parts are "rusty". A joy to work with.

By the same token, standardized power outlets would be an affront to the free market and an impediment to progress.

One example of progress on power outlets I know of is Denmark: Here the non-grounded plug has been compatible with Schuko outlets as used in most of the rest of Northern Europe, and Schuko connectors will fit in the outlets without ground connection.

Since most appliances come with Schuko plugs, a decision has been made for new installations to use the Schuko outlet, allowing a gradual transition to the Schuko standard.

Have you looked into some of the "fantasy consoles," such as Pico8 [0] or TIC80 [1]? These emulate "8-bit machines" with graphics and sound, and are completely self-sufficient systems. Compared to real 8-bit machines, your creations can easily be shared as they can be exported to run directly on web pages. The shared place for projects is also a wonderful place to learn from others: from running a game to inspecting the code is a matter of pressing `esc`.

My favorite as an old-timer who is comfortable in most things from assembler to Mathematica has been "Programming Rust" from O'Reilly [0]

The book does a really good job at explaining the thinking behind the abstractions available in the standard library. To me, this was the book that made everything click, so that I did not feel I was fighting against the language.

Completely agree. My childhood nightmare from maintaining my cheap commuter bike was the old crank-arm attachment system with wedges (or "cotters", I just learned [0]). I used a mallet to get them out, and with my low level of control it took a bit of luck to not bend the thread.

Also, back then there was no ways to get parts: I could go to the local bikeshop, but the selection was small and the markup on spares was insane. Replacing a drivetrain (as I now do every second year) would probably cost more than a new bike. These days I can order parts and tools at incredible prices and have them delivered the next day.

The "ocean fertilization" referred to here is not with nutrients, but with iron [0]. Apparently there are glacial runoffs at Greenland which would just need to be transported to other areas of the ocean in order to capture massive amounts of CO2.

With regard to security, it seems to me that the most obvious comparison for the ReMarkable would be a paper notepad which would also be compromised if you had physical access?

Saying this as a former ReMarkable owner (and kickstarter backer) who ended up only using the device as a notepad, after learning that I read in a non-linear fashion which doesn't work well on the relatively slow screen. And for notes, I ended up deciding that paper is simpler that dragging yet another device around.

Still, I highly recommend the ReMarkable and my device happily lives on as a school notebook for my son.

Just for context: I grew up in a small village in Denmark. My window to the world was one-hour bus trips to the nearest town which had a decent library, including some computer magazines.

None of my peers did any programming, and since Denmark does not have flat-rate local calls, calling up via modem to connect to a BBS was never really an option -- so there was really no-one to share with. That is certainly somewhere were the internet would have been a plus.

Yup, was thinking Anderson connectors as well -- I use one to power my trolling motor.

Have to upvote - just because Z80: I spend my youth programming this thing literally in hex: To program my Amstrad CPC646, I wrote down opcodes on a piece of paper and then manually translated to hex according to a copy of the Z80 spec sheet I found in the back of some book. Relative jumps were especially fun...

If only I had had the internet, maybe I would have stumbled on the concept of an "assembler". Not sure if it had been more fun? In any case, I did not find the protected mode.

Well, sometimes at least: We moved from Asia (Singapore) to Europe, and while waiting for our movers to arrive, we checked the childrens bedroom in the new house against the dimensions of their beds _looked up on the European IKEA site_: The bed would not fit.

When the movers came with our container, I checked the dimensions on the actual IKEA bed we had bought in Singapore: It was smaller than the European version, and fit perfectly into the bedroom.

This looks very well done. In particular the web bookmark database is something I have been thinking about doing myself.

One thing that I would do differently is how titles are handled.

`nb` will store the title in front-matter metadata and set the filename to a slug (spaces to underscore etc.). For externally added files, both metadata and markdown level 1 headings take precedence over filename. If neither are specified, `nb list` will show both filename (with extension) and first line of content.

I have used markdown-based notes since notational velocity came out 20 years ago. Along the way I have used many different tools, and have come to prefer a filesystem-centric approach where the title is used as filename if at all possible, and the only override is explicit front-matter metadata.

This approach makes it easier to work with the notes as simple files on your phone and in the terminal.

I totally agree that we need a standard -- but it is already here: markdown files with YAML frontmatter, github-style checkmarks and hash-tags. All synced via your favorite filesystem synchronizer.

This is supported by the tool discussed here (`nb`), and over the last 20 years, I have used it with all these tools:

  - Notational Velocity (macOS)
  - Resoph Notes (MS Windows)
  - nvPy (cross platform)
  - Obsidian (cross platform)
  - 1Writer (iOS)

Back in the 1990's when fractals were a big thing and computers were not very powerful, the go-to tool for exploring fractals was a highly optimized integer engine called `fractint`.

In the final form it supported many types of fractals via a domain-specific language. You can still download the source from https://www.fractint.org/.

Porting this framework to your garden might be worthwhile?

In "Sapiens: A Brief History of Humankind," Harari claims that human brain size has decreased since the agricultural revolution (which fits the whole downfall story of course).

A bit of googling for backup reveals that things may not be as simple, but it is not clear that current societies are selecting for brain size.

As posted elsewhere, the Danish government has almost no financial stake in Vestas.

If they did want to make Vestas their champion, they could make Ørsted, a global leader in offshore wind in which the government has a majority stake, buy Vestas turbines. As it is, Ørsted has historically only bought from Siemens and GE.

In reality, Vestas is based and rooted in Jutland “far” from the capitol.

The `ndarray`-concept seems to have caught on across languages for data-analysis. I have happily used `rust-ndarray`[0] for building python extensions in rust.

Yes, we will never need more than 12 quantum computers or so /s

Computers today are used to solve the problems computers can solve: this is as vastly larger class of problems than envisioned by anyone 50 or 70 years ago, but there are still many computational problems that we do not solve.

These unsolved problems are often only known by domain experts with a deep understanding of why a specific domain is addressed by a given model.

OP's comment makes perfect sense to me, but how I have read your comment three times without understanding what it is you want to communicate?

This is the same with PIN in Europe (at least for contactless): Below a certain amount you do not have to enter the PIN.

Since the current answers only consider albedo-tuning and mechanical CCS: Ocean fertilization[0] may be another solution to carbon capture.

The idea is that iron is the main limiting factor to algae growth, so that adding iron to currently barren areas in the oceans would allow algae growth on a very large scale.

At some point I saw a report on the actual numbers (was working in a big wind power company and a colleague was heading our research on this topic). One big take-away for me was that the number of bird fatalities due to windows in high-rise buildings was orders of magnitude larger than the number caused by wind turbines.

Thank you for posting this: This also has the Danish real time data presented in a much cleaner way than the various web services of our local operators.

One tidbit on information damage that has stuck with me is that carcinogenic radiation damage is a second order process: to get a cancerous mutation you need both copies of DNA damaged, which would in most cases require two separate events.

To the extend this is true, it implies that it is the square of the radiation dose that determines carcinogenic effects: Half the dose would cause only a fourth of damage.

Thanks for posting, this sounds super cool. Now I just really wished I had a reason to order a molten salt loop.

This appears to differ across Europe.

I know for a fact (through living here) that Denmark and probably the rest of Scandinavia has property tax and inheritance tax -- holding on to family property is almost as expensive as buying new property.

Which part of Europe are you referring to? I once had Greek colleague who complained about having to maintain three generations worth of houses, so that might be one place where things are as you describe?

From an engineering point of view, planes would be close to the bottom of the list of fossil fuel uses to transition to hydrogen/other "X-fuel" [0].

Still, my cynical part expects that we will see renewable-powered flight as a relatively early (premium) use of power-to-X for the sole reason that it will allow the affluent and/or powerful to fly while claiming to be climate neutral.

[0] Our society uses insane amounts of hydrogen. One fundamental use is for synthetic fertilizer which supplies around half the nitrogen input for agriculture, without which we would be hard pressed to feed the world. This hydrogen is currently produced from fossil fuels.
