You can visualize 4D objects by visualizing morphing 3D objects (i.e. use time as the 4th dimension). Where it becomes tricky is 4D rotation, but I suspect that after a while you can get some limited intuition for it.

Now I wonder whether it couldn’t also be visualized as the cross-product of two 2D worlds. We have two eyes with a 2D retina each, so maybe they could be trained for that. 4D obviously requires more representational space in our brain than 3D, and the per-eye visual processing apparatus would be limited to the respective pair of dimensions, so the internal visualization will probably have to be more coarse-grained or blurry in some way.

You need to spend at least £600 to get a decent home espresso set up but it will get you something pretty close to good cafe grade coffee.

The reason those big £3000+ machines are impractical for the home is not the cleaning or even the warm-up time (as both of those factors are the same for any espresso machine even the home ones) but rather with the fact that the bar grade espresso machines expect to be plumbed into a reverse osmosis filter and take up a shitload of space.

Commercial machines may need a little bit more time to warm up but I still let my gaggia warm up for around 15 minutes before I use it otherwise I find consistency falls and I just get frustration.

Regarding cleaning, the process is the same for home machines and just needs to be performed less often (I do this around once every week depending on use. I pour 1-4 shots a day every day). There are powdered detergents which are used to backflush the group head and solenoid valve to clear out coffee oils, this process takes about 5 minutes to perform and doesn't require much manual effort except for clearing out the drip tray and wiping things down a bit.

When it comes to cleaning the boiler, this isn't done by disassembling the machine or anything crazy like that. An acidic solution of usually some combination of primarily citric acid and/or potassium bitartrate is added to the water reservoir, the boiler is then flushed to get the solution in the boiler, I will then usually leave it in for 15 minutes with the boiler turned off to prevent water from boiling (to make sure all areas of the boiler are in contact with water at all times). Then this gets flushed with clean filtered water to get rid of the acid.

This process takes longer but also doesn't require much work.

Anything under £600 will give you mediocre espresso (due to grind inconsistency and temperature stability problems) or fauxpresso (any pod machine or bean to cup machine basically maxes fauxpresso, there are very expensive commercial grade true-espresso bean to cup machines but these, even when dialled in correctly, still usually make a mediocre espresso).

Any machine (even the fauxpresso ones) will likely require almost as much cleaning effort. Any manufacturer which claims otherwise (especially for bean-to-cup machines) is just trying to reduce the lifetime of your machine so it fails out of warranty and you buy another one.
I suspect the wield this lack of choice as a weapon against the carriers. They go to each carrier and say, "that a healthy looking Amazon contract you've got there. Shame if we suddenly stopped sending packages your way", then squeeze them for price. Harder to do that if Amazon let their customer pick the carrier.

I've certainly been part of something very similar, where a company has multiple suppliers providing the same service. Near contract renewal time we would move our volume on their competitors to remind them that they needed us more than we needed them. It was a very effective way to get them to keep lowering their prices as the years went on.

There is also probably also a logistics piece as well. Amazon will be shipping products to carriers last mile hubs or similar themselves, rather than having a carrier handle the entire distance. Which makes it cheaper for Amazon. So carrier will also be picked based on which hub is nearest to one of Amazons warehouses, how full the Amazon truck going there is, which warehouse has the product etc

I would be surprised if Amazon had the same non-negotiable-take-it-or-leave-it terms with Bose as it has with others.

Which raises an obvious asymmetry: Amazon makes no guarantee that it is not offering more favourable terms for bigger suppliers – and although mere speculation, I would be surprised if that didn’t go on, because I seem to remember traditional retailers doing similar things.

I’m not saying this is good or bad, just pointing out that with all retail there has been almost a phase transition once the supplier is a household name, and the dynamics change almost to the point where retailers would offer their products at cost price or even a loss just to make sure that their customers could buy the household name through them.
I personally maintained a two-shift sleep schedule for about a year, with a 2-3 hour gap between shifts. It did work surprisingly well for me, leaving me feeling both physically and mentally refreshed and rested. Societal obligations forced me to move back to a traditional sleep schedule, but I could definitely see going back to that if conditions allowed it.

It has virtues.

As someone who works in applied Cryptography and has also worked for the European Central Bank, we need “crypto”.

1) seigniorage is an abused privilege. Source: US debt ceiling at 27TRN.

2) permissionless money has value, I cannot send more than 5k a day using my bank. I can send any amount using crypto. I also don’t need two utility bills and an address to open an “account”

3) it’s censorship resistant. Govt’s can’t just stop payments or shutdown the network.

Use Monero.

The difference is that the lab leak hypothesis is being vigorously debated out in the open for all to see, by journalists and scientists from multiple countries, with references cited and available for perusal.

Does this apply to things where it obviously went wrong? E.g. if someone bought a 5lb item, and they pointed out you shipped them a 1lb box-- no refunds even then, if they're an undesirable customer?
I mean by now it should be clear to everyone that there are certain trade-offs in the choice dynamic vs static typing.

I do like clarity of static type declarations, also the absence of weird polymorphism like functions returning a number or al ist of numbers depending on their parameters, etc.

But then, many statically typed code bases are just tested abysmally. It is as if the type signatures would constitute proper tests. I realise that you don't need to write as many tests in a statically typed setting, but in many cases - and esp. in underpowered type systems - the types won't test the program's logic.
Very good observation

Trust seems to be the main issue for large purchases, but individual retailers cannot (and probably should not) know enough about a customer to trust them.

Could the retail organization use a physically distributed escrow service to somehow tie payment to physical goods delivery? That essentially outsources the "brick and mortar" aspect to a third party and removes delivery risk. Amazon and Currency Exchange, for example, can have a much healthier economic relationship than Amazon and me.

Alternatively, this sounds like it could be addressed as a sort of "consumer protection" insurance similar to my homeowners or auto insurance. I file a claim so insurance covers legitimate large losses. Risk is pooled and the underwriter is the organization that is evaluating my trustworthiness, not the individual retailers.

Just ideas off the cuff, maybe there are huge holes here.
Bitcoin mining on anything other than ASICs is fools errand for many years now.
Can you expand on that? This is my understanding so far, feel free to correct it:

It looks like a good place for quick key-values lookups. It's a "table" as a service, with 1 (or 2) columns that you can index on. Anything else and you need an RDBMS.

It's useful for simple storage, without the overhead of setting up an RDS.
> but it's way too complicated to quickly debug things like seg faults

I know you've listed the common argument for static vs dynamic (dynamic -> so fast to code but slow to run, static -> way too complicated)but after a decade in SE I still have yet to see some good evidence of this.

Yes some static languages (like Java) will make developing certain things slower vs JS but is Java a good statically typed language ? Maybe these statements are "true" today with the current implementation of one or the other but there are a lot of languages that I just can't see getting in the way.

A new example of this: Kotlin and Swift are statically typed and I would love love to see where it slows these mythical developers that are so fast in a dynamic language but would be slowed down using them. There's obviously going to be a cost for the actual compile time but that should be minimal.

Unfortunately I'm starting to believe that this is just another case of certain developers are used to certain languages.

The trend of the JS move to TS also points to this. Basically JS looks very similar to Kotlin and Swift (TS is basically identical).

To look at your specifics
> Dynamic languages let you introspect and modify things way more easily, and this makes things like fakes and mocks for testing way easier. It makes debugging easier. And not having to wait an hour for something to compile is nice.

> Dynamic languages let you introspect and modify things way more easily

In what way ?

> and this makes things like fakes and mocks for testing way easier

Fwiw this is what that fake/mocks look like for a static language
`val x = mock<User>()`

To be fair that's using a library and maybe that's part of your criteria ?

> It makes debugging easier

? how, I can see the argument for the other way (one less thing the developer has to worry about - typing issues) but how is dynamic easier to debug ?

> having to wait an hour for something to compile is nice

Completely Fair. Now whether or not the thing you're working on would take an hour to compile I highly doubt. If you're working on a project that would hypothetically take an hour to compile then I really hope it's not written in a dynamic language.

Not trying to pick on you at all, I believe a lot of developers would agree with you but I'm starting to think that there are developers that are just used to one or the other. I have to point out that I could be thinking this way with respect to statically typed languages but I really have a hard time seeing this point (as I would be if I was falling into the same trap I'm "accusing" you of).

The link you provide as context contradicts 1, if I'm reading it right? It says that Fauci does not want to fund this research.

The beaker example is the worst one, because the shape of the beaker is meant for controlled pouring out one point and no spills anywhere else around the perimeter.

I studied journalism at college as part of a more general media studies course.

It does help but I am not sure I would describe _my_ education as a panacea.

The main reason it was good was because it helps frame how you think of writing,

The most important things go first. Statement of fact, then you go into what the implications are, then you start introducing less and less relevant elements.

when you’re writing you keep the 5 “W’s” in mind, make sure you answer them. (Who what where when why), for instructive documentation you add: How.

Obviously an education bakes this into you in a better way than I can convey here.

What I learned is probably only decent for writing overviews.

Personally I find structure to be the biggest bottleneck/difficulty when making documentation.

What do others normally struggle with that don’t have this education?
So many comments mention bidet vs toilet paper or bidet as a solution to toilet paper shortage. This is so weird to me (and I guess to others raised in countries where the idea of not having a bidet is not even considered) because in the way we are taught the two aren't mutually exclusive, and I ain't talking about using toilet paper to dry yourself. Sure, one can manage with just one of them if needed but still... ¯\_(ツ)_/¯
Read what they wrote again, but this time replace "static" with "compiled" and "dynamic" with "interpreted", and suddenly it made sense to me.

It's true that overall, compiled languages tend to be more static, and interpreted languages more dynamic (and there are good reasons for why they end up that way besides mere convention), but nevertheless that's not what this discussion is about.

If you want espresso you probably want steel burrs mounted in steel with good bearings.

If you are on a budget and don't want to spend £500 ($700 + tax and shipping) on a niche then you can usually find used smaller commercial machines. Research the burrs they use and see if you can find new burrs, this way you can spend probably somewhere around $200 on what would function like a brand new high quality burr grinder.
