DC faults are far harder to interrupt than AC ones at the same power (may not apply above 5~15 kV).

Also, power balancing via frequency-tracking is fairly easy. I guess you could just rely on voltage targeting for the local level (up to an apartment complex), and do something else to handle distribution infrastructure.

But yes, there is nothing fundamentally stopping you from putting separate 300-ish V DC wiring in your house and feeding that directly to compatible switched-mode power supplies.
Rule of thumb: universal (120-240 V) supplies that don't need to be switched between low and high range can handle the current in the input rectifier (you'd only use 2 of the 4 diodes, but at 120 V they have to handle double the current anyways), but active PFC could get confused.

If you have fixed ceiling LED lighting, you may be able to re-wire it for series operation, but that requires sufficient understanding of the isolation voltages between cases and input connections.
In the end, there would be a DC to DC step-down regulator. E.g. Meanwell has suitable LED drivers in their catalog that officially take ~300 V DC.

For the solar panels, you'd just need a high voltage DC MPPT, likely a step-up converter for ~320 V DC (~230 V AC peak).

Theoretically such a DC supply could be provided by just rectifying a 3-phase supply in star configuration, as that would get a decent power factor (actually better than most passive PFC SMPSs) with just 6 diodes (and 9.5% RMS ripple). There is a related configuration that needs a transformer and uses 12 diodes to get 1 % RMS ripple, but as I just realized, they produce too much voltage for the somewhat-common DC-tolerant SMPSs: 538 V DC from a 3-phase 230 V (phase-to-neutral) AC supply.

You'd need active PFC or a transformer to get decent power factor at compatible DC voltages.

Just to be clear though: the solar panel wants to feed a switching regulator for MPPT, even if you specially configure it to supply some LEDs straight from the outdoor sun (no battery buffer, brightness fluctuating accordingly).

You could however totally shift that MPPT switching regulator to the battery charging, so your computer and LED drivers take the raw panel string voltage, as they have internal regulation. The MPPT would likely still have a current sense shunt at the panel output to accurately perform it's MPPT duties, but that'd be faulty if it'd get toasty (precision and heat don't like another).

> tackling climate change should be a secondary priority to (why it should wait for) addressing these other local issues FIRST

That is very much situational. A big part of why climate change is bad is because it will cause complete ecosystems to collapse. If dams or anything else accelerate that faster than climate change, there is an argument to be made that they should take higher priority. In the case of the Kennebec River that's exactly what happened.

As you note, for facilities like data centres that are engineered for a specific type of load, a building-level rectifier makes sense. For a home where you have many devices using a little bit of power at a variety of voltages, you're going to end up with lots and lots of small DC converters everywhere which defeats the point. Just run 120 VAC.

Hyperparameter Tuning in Deep Neural Nets
I solved it with AirMessage by SparkDev - runs directly on my iPhone. There air similarly named apps and macOS based implementations as well that would work, but I prefer keeping it on my phone instead.

As far as the Alt- switching goes.. that was honestly one of the more difficult things to solve for both Linux and Windows. For Linux because of the sheer number of DEs (a few absolutely hated it to allow certain remapping, had to send in patches for one of the DEs too!) and Windows because it initially appeared that the most simple remapping methods would clobber each other - but after working with Autohotkey enough it was apparent that it was indeed up to the task & I also kicked Sharpkeys registry hacking off to the side and no longer needed users to log off and back on. (Also makes pair programming a bit easier too.)

I can confirm the strong deterrent towards having a credit card, any personal loans really, in the Netherlands.

My bank, and I believe most banks in the Netherlands, requires proof of stable income well above minimum wage before even considering an application for a credit card. This puts credit cards out of reach of a sizable part of the population.

Also, credit checks and reporting new lines of credit to the authorities by lenders are mandatory for all personal loans, be it for getting a mortgage, issuing a credit card, paying monthly installments for a smartphone bundled with a contract, or buying on credit from Dutch online stores or mail order catalogues.
Thought experiment: What if they auctioned off like 20% of the vaccine supply?

You go to a website, enter how much you're willing to pay, when cleared funds are received your bid will be entered in the next weekly allocation, if it's above the winning threshold you pay that much and get told when and where to show up.

First couple weeks it'd mostly be the 1% paying $10,000 for their shots. If you're old or have medical conditions and COVID will probably kill you, you might be willing to pay $1000-$3000 to skip the queue and get the shot super early.

People who've slipped through the cracks would get another option. If you have XYZ disease where COVID would be bad news but your condition somehow didn't get on the official list of conditions for jumping the queue, you can still mortgage your house or max out your credit card to get the dose.

Ethically people would say it's terrible, but I'd say it's ethically okay to let a rich guy go first and then use his money to pay for 1000 poor people's shots later.

Some people will find ways to get around the queue anyway (lying, leftovers or black market doses), it's better to give them a legitimate way to skip the queue that you can still somewhat regulate and extract the value for some beneficial purpose.

Part of what you're saying is a good point, IMO. The people who transition the infrastructure from Level 0 to Level 1 won't be the same people in charge of infrastructure when it's time to transition from Level 17 to Level 18.

But however many levels there are from garage infrastructure to Big Tech infrastructure--even if there were only 2--someone will always have to decide that the time has come to transition from This Level to Next Level. Different expertise may be required to transition from L0 -> L1 vs L10->L11 vs L30->L31, but that expertise still matters.

And if I were the one who had to decide at any of those levels, I would want a well-designed plan for the next transition or two that was of the form: 'When [some measurement] reaches [some threshold] we will [change the infrastructure in the following ways...]'

I wonder if it's a viable start up news idea to have deep investigative journalism like articles that all have a sister article written in an Axios style that boil everything down to the major points.

The article was well written but I just am not interested that much in hockey to read the entire long form without any idea of the general points.
You forgot the magnetic trip of the breakers and the now-mandatory RCDs. The latter are far more complex than a simple rectifier would be.

And even then, there's no reason such a rectifier module couldn't be a pluggable module. They still last 10~20 years, easily.

I don't see what all those low voltage rails should be for. Computers typically work fine on 300~350 V DC, and if anything, there is reason to go from 12 V to a higher supply bus voltage, actually deployed in some modular servers by now (with a 48 V bus between the local battery backup modules, AC-fed supplies, and motherboards).
What you call readline controls I call wordwise - but yes that is indeed supported by Kinto. You will want to undo any of your custom remaps on modifier keys before you install Kinto as it will not be aware of your own remapping attempts. Going forward you would also be best served by updating new keymaps in ~/.kinto/kinto.py if you can do so.

I do not yet have a method though to help you easily keep your changes when upgrading to newer Kinto versions. I will try to add a git like merging ability to the updates later on though, so custom local changes will be preserved.

I wonder what the version of the old "if you don't test restoring you don't have backups" rule is for these new services. Restoring costs money and laptop users don't have good ways of doing complete restores just for test as it's a lot of downtime.

Maybe it needs a kind of stochastic automated approach.. a program that finds sufficiently small (vs costs) sample of files on your computer (some old, some recently changed, etc) and tries restoring them and verifies.
> 100% worth it

I'm not sure the value proposition is clear cut. In terms of security, while the server data itself is secure, and the nature of the transactions are inscrutable, there's now reason to share a single key between multiple users, and only one of those users needs to be compromised. The key could be generated and stored in some super secure silicon with a small attack surface, but if the data needs to be available to multiple users, you're back to duplicating and distributing the key, and social engineering remains the best attack vector. A benefit could be gained with multiple users with multiple keys and limited sharing to reduce vulnerability, like sharing sensitive documents between between select individuals. But that's a pretty niche use case.

Just go to a higher voltage already, if you go for DC. Most computers e.g. are fine with 300~350 V DC (and would not be fine with 120 V DC, as the high-voltage side of their power supplies isn't designed for the current you'd have at "just" 120 V).

Yes, submarine power cables quickly have to be DC due to capacitance between the cable and the ocean. Compensation for that is neither easy (middle of the ocean) nor cheap.
Absolutely. The main answer is going to be permanent geologic storage in depleted oil wells or saline aquifers, which is widely agreed to be one of the most scalable form of carbon sequestration. We're also hoping to turn the CO2 back into fuel right at the truck stop, so we can put it right back into the trucks!
The US uses 120v AC because incandescent light bulbs and heaters that ran at 100v DC would work at 120v AC. It allowed upgrading the original DC grids to AC with minimal impact.

Like most of these rants against "censorship" they skip over people's rights to restrict speech as a form of speech itself: there is no moral (or legal) right to give people you disagree with a forum or audience to express their view.

Calling to silence others (that is, encouraging them to take your view of not giving them an audience) is fine as long as people have a choice on how to respond.

If there is some notion that we have no choice but to enable other's views then our own views become secondary to them. We no longer have absolute control over expressing the views we agree or disagree with.

Is the government or some other absolute authority censoring wrong? Yes. Are powerful monopolies (or near monopolies) wrong to censor? No, because they have the same speech rights as others, the problem there lies in the market power of the monopolies, not their speech.

I think of async functions in rust as regular functions that happen to return a Future. Sure to do something useful you need to use an executor (or follow the semantics of one) which uses a context to track the progress through a state machine until success or failure. But it isn't from a different "universe" (color) of functions. That's the big difference here from say Javascript. At least that's how I explain it to myself.
It's obviously just some commented out code in this simulation we live in
It's more a case of parallel and somewhat divergent evolution.

Current PC keyboards, minus the Windows key, are nearly identical to The IBM model F that came with the IBM 3270 in 1983 [1] (the arrow keys are quite different). (Note: IBM is responsible for this, not Microsoft)

The Apple IIe also came out in 1983 [2] but had a very different layout from what Apple uses today. The "open apple" and "closed apple" (two different modifiers) were all that was on the bottom row, similar to left and right command. Control was located above, and option was missing.

Macintosh's keyboards kept evolving well after PC keyboards reached their final form, aside from the addition of the windows key in 1994 (that was microsoft, not surprisingly).

Every platform has had it's own ideas about what keyboards should look like. In terms of current user-base, the clear winner is the IBM PC keyboard. It was more justifiable for manufacturers to go their own way in the wild and wooley early 80's while everyone was inventing their own way of doing things. Today, when the same software runs on multiple platforms, it's an annoying problem.

Maybe it was in the beginning, but Terraform is far more powerful than that now. Terraform is a monad that neatly separates pure declarative configuration from the I/O (side effects) that are factored out into providers. Terraform used at its most powerful is not limited to infrastructure, it also sets up the platforms and applications running on that infrastructure for you, by separating the configuration of the platforms and applications from the generic API calls that apply that configuration. Terraform's dependency graph ensures that the calls are made in the right order, no matter if they are made to infrastructure APIs, platform APIs, or APIs belonging to layers further up the stack
