On one hand, I like the color combos listed as good (without much context) more than the counterexamples, but like most design writing, it's filled with invisible "Citation Needed"s.

The justifications are mainly like this one: "That’s because these warm colors and blue are super versatile for categories." Or "First, forest green is just very dark. And lightening up the forest green means going into an awkward neon". This begs the question: "Why is green either too dark or awkward?"

I'm guessing this is due to us not understanding the psychology behind it; we fall back to rules of thumb.

Personally, I don't think there is anything like it. Since it is an adhesive you can do things like glue broken pottery. Or you can cover it with tiny pieces of egg shell (rankaku). You paint on goo, cure it in warm&humid environment and it becomes food safe, water safe and alcohol safe. The curing changes the formula so it is no longer toxic at all.

I know some people who are very diligent about contact and manage to work without getting a rash. If you want to go that route you have to be very diligent.

I am not that neat so I just went with it.

I'm curious how they hope to deal with alternative materials (PLA can do this but good luck trying to get that to work with TGLASE or P90 or HDPE. Also thinks like ABS that shrink and so a heated base is essential would be challenging on a belt.

The reasoning is that the internal design of devices like phones/tablets/etc cannot take self-repair into account when the priorities of most manufacturers these days are to make them small and light (not to mention things like water resistance which also poses design problems). Focusing on user-replaceability makes the design process much harder with these restrictions.

Personally I doubt that's the _only_ reason things have gone in this direction, but it's certainly one of them.
A monoid is a set S with an associative binary operation and a unit. For instance, strings with string concatenation and the empty string form a monoid.

Functions form a monoid as well. Function composition is associative and id is the unit.

This is already a solved problem, we tax income rather than wealth. I assumed it was clear from context the 90+% tax is an income tax. It only applies when they sell (or die, as inheritance tax).

So none of your concerns over who would have the money, or whether foreigners would gain ownership, would have any relevance.

But since you seem interested in wealth taxes, for people who advocate that instead, the strategy there is very different -- generally something like ~2% per year (2% yearly would add up to 70% after 60 years), which for public companies presents zero problem since the stock market is constantly purchasing shares anyways. And just like many companies have non-voting shares, selling those would prevent dilution of control.
Rep. Nadler called Antifa "imaginary" on the floor of the House of Representatives.[1] I haven't been able to find the full quote with context, so take that as you will. The Daily Beast (not exactly representative of mainstream journalism, I concede) published an article saying ""Antifa" doesn't exist the way Trump pretends it does."[2] Whether those are extremely fringe is left to the reader.

DuckDuckGo admittedly returned more results from right-leaning sources clutching pearls that Democrats and media outlets would dare say such things than results from left-leaning sources saying it explicitly. Such is the nature of the polarized times, I suppose. But I have a few left-wing friends who have said similar things.

> The part you haven't really touched on though that is critical to take into account, is what it means for a system and it's authority to be in that state when the components that make up that system exist independently from the system.

An excellent point

Looking at a human composed system, the humans have organized and accepted a state-of-affairs composed of a set of collective delegations of authority. Wipe out that set of delegations, you wipe out the authority, the system is essentially in a reset state (implying a higher order meta-system, but let's not go there).

You are then left with the challenge of developing a predominant consensus amongst the components of the old system in order to set back up the significant network of functional working relationships, and thereby, functional authorities.

It seems to me like the most efficient way to accomplish this would be to temporarily retire a system in order to have time to revamp/rebuild it. In order to do this effectively, you would of course need some temporary hold-over system. This holdover would not need to accomplish all of the functions of the original, but just enough so that things don't fall apart.

I don't really know how this could be implemented in a general way, but for the school system, it could look like:

1. Schools close and go remote (Already mostly happening due to covid).

2. School system audited by teachers/professional educators.

3. After auditing, superfluous elements of the system are removed, and missing elements added.

4. Re-open, following the new system.

That being said, I'm kind of an idiot, and don't really know what I'm talking about. Also, as you stated:

> All of this [is] much easier said than done.
> Some of the most densely populated countries are the poorest and unhappiest.

Sure, there's a golden mean between slums and unwalkable suburbs/exurbs.

Interestingly the urbanization percentage for the US is basically the same as for Norway 82.5%. And interestingly Oslo about tenth of the size of LA has comparable density: https://www.ssb.no/a/english/kortnavn/beftett_en/fig-2011-06... (per km^2) https://i.redd.it/v84al8v4ymp11.png (per mi^2)

"About 14% Americans live in the nation's rural counties, 54% in its suburbs and small metros and about 30% in its urban core counties" (data from 2016)

and in Europe "In 2018, 39.3% of the population lived in the cities, 31.6% lived in towns and suburbs, and 29.1% lived in rural areas"

> Regardless, we're at the point where we need to seriously consider the long-term sustainability of the current global population level.

Well, this sounds like the good old Malthus argument, but we're nowhere near carrying capacity of Earth.

From math: https://en.m.wikipedia.org/wiki/Monoid

A monoid is a concept from math. They have a set of objects (like the integers), and a binary operation (like addition or multiplication over integers). The operation is associative (like addition where the order you compute a set of additions doesn’t matter, you get the same sum). And there’s an identity element (in addition this would be 0).

For CS there are some nice results where the operation can be automatically parallelized. Useful for things like MapReduce if you need to run things at large scale, or in this case for distributing the work over the many shader units of a GPU.

This is my opinion as well. Many of the power user commands I've learned were to avoid annoying and fiddly things. It is less about saving time and more about saving effort for me. With occasional RSI, if I can use a couple hot keys to save 50-100 typed characters, it is very worth it to me, both for time and effort and to minimize the annoyance-factor of doing the same thing yet again.

No one with any scientific background would make this claim. Le Chatelier's principle has the opposite effect. Equilibrium changes slowly.

> There was no Linux when Sun took that decision.

True, but initially Solaris (and the compiler unbundling) had no impact on the Sun user base.

The initial release of Solaris was... not that great. I remember universities and research labs (entities which provided a lot of the open source effort) held out upgrading for a long time and stayed on SunOS for years.

So by the time most organizations finally upgraded to Solaris, Linux was established but not very strong. The timing was just right (or wrong, depending on POV) for the compiler unbundling to start pushing people (me included) to Linux.

(Although then I joined Sun and lived happily in the world of Solaris for many years.)

I actually pick type. I'm pretty fast and I can do it without looking at the keyboard. Although I can't switch keyboards easily and I buy multiple of the same keyboards at a time because of this. I've found it doesn't hold me back compared to touch typers. Data entry speed is just not the bottleneck. On my best day I might write between 500-1000 lines of code, which is just not that much typing spread over 8-12 hours. Average days are adding/modifying maybe 200 lines. Typing or editing speed here just really isn't the issue.
>most manufacturers these days are to make them small and light

I bought pretty much the smallest phone with decent specs I could find when I bought my last phone. Most of the new flagship phones were huge. Like things that would not fit in my jeans pocket with my wallet. None had a replaceable battery. Yet, i've had plenty of small, light, sturdy, water resistant phones with replaceable batteries.

I really have a hard time believing that argument i'm sorry. The only real reason I can see not to allow replaceable batteries is to increase profit for manufacturers. Same with every other 'feature' i've seen marketed to people with the same excuse.

It's nonsense. There's alway a profit motive behind things and the bottom line is...

The less modular consumer devices are, the more restricted our abilities to repair, modify and use our devices become, the less user friendly they become. The only ones benefiting from removing modularity, repairability and turning devices into black boxes without standardized parts requiring either replacement of the entire device or specialized repair services are the manufacturers period.

It's not consumer friendly. Anything else is marketing bullshit to make people accept less control over their devices and more profit for device makers.

There's zero legitimate consumer friendly reason not to standardize things and allow easy repair of devices, including replacing batteries, again a long standard feature in consumer electronics.

Just because it takes a couple years for batteries to die now, doesn't mean they don't die and need to eventually be replaced like old alkaline batteries. The time scale doesn't change the fact that eventually, yes they do need to be replaced, like any other batteries in battery powered devices.

You can convert cellulose into glucose but it takes things like this (special cultured bacteria, extremely processed cellulose, and an ultrafilter to remove glucose to drive the reaction): https://onlinelibrary.wiley.com/doi/abs/10.1002/bit.26022080...

Or strong acids and 190°C over a catalyst.

Cellulose is remarkably strong, especially with lignin in the structure too. We're lucky anything can digest it at all.

Which brings me to mycology, probably the best way to extract energy from cellulose for humans. Sterilize, inoculate, keep moist, and harvest a significant percentage of the source material as good carbohydrates and protein.

Too costly.

We are not accounting for this yet, as soon as you take a second to think in at least 6-year time horizons, it starts to sink in.

It's funny because I used to love 'new tech', and now I'm instinctively against it, knowing nothing about it other than 'not standard' is enough to make me feel the amount of extra labour required to deal with it. I like movements such as 'Rust' whereby we see a legit challenger to a foundational tech, but with enough enthusiasm and long term vision that one day, it will be a possible 'off the shelf choice'.

Node.js uses libuv for async file operations -- And libuv has its own internal thread pool to make file ops appear fully async to a node program.

From the libuv docs [0]:

Unlike network I/O, there are no platform-specific file I/O primitives libuv could rely on,
so the current approach is to run blocking file I/O operations in a thread pool.

"how obsessed we are with giving milk to kids because it’s so healthy"

The word "because" is a fascinating bridge. Whatever follows after reveals unstated assumptions hidden deep in the speakers mind.

I'm objecting to the specific premise that it's some rational decision made individually by each parent based upon nutrition.

Instead I'm claiming our cultural habit of feeding of milk to children is entirely manufactured by the organizations that produce it. There's lots of documentation to demonstrate this.

Whether or not it's a good idea is immaterial.
