> That "manipulation of hydrogen" mostly involves use in the the chemical industry. We don't use hydrogen to power gas turbines.

So, when you said hydrogen rapidly corrodes any metal it comes into contact with, that didn't include the metal that the chemical industry makes their equipment from? So, let's just put a "this is chemical industry" signs on our hydrogen storage plants, and presto! Magically protected!

Note that one of the things the chemical industry does with hydrogen-rich gases is burn them in combustion turbines, just like in a proposed hydrogen energy storage facility. Turbines for burning hydrogen have been available for decades. See, for example, what General Electric says:

https://www.ge.com/power/gas/fuel-capability/hydrogen-fueled...

"Our turbines have nearly 30 years of experience operating on a variety of fuels that contain hydrogen, totaling over 6 million operating hours as hydrogen-fueled turbines using concentrations ranging from 5% to 95% (by volume)."

> Aside from that, I found the memorable thing about the book to be the stories of how surprisingly effective checklists are, what a difference they can make, and how and why things have gone wrong without them. All that stuff you would cut as superfluous.

I summed up the book in one line, one line doesn't do it justice. The points you mention would be included in a good summary.

I guess my expectations simply differed from reality. I was expecting more practical advice on how to design good checklists, what pitfalls to avoid, good practices and so on. What I got instead is different stories where he shows that checklists work. Personally I did not think that more stories added much substance to the general message, but I get your point and it's certainly a valid criticism.
There's a couple of old fashioned misogynists who feel very threatened by the idea of RMS finally facing consequences for his behaviour, and they are pulling out all the stops to suppress criticism of RMS and the FSF.

Various justifications will be applied -- it's a "divisive topic" or its "political" -- but it's just different types of denial.

That would be surprising. But, my experience has generally been that when a result of Euler comes up in class, it's more frequently preceded with "this was published by Euler but not really rigorously proven." Standards of proof were obviously different 250 years ago.
The idea that that Erlang is the most mature language and that algo stuff actually matters for a regular coder is kinda funny
It's not cynicism, it's understanding capacity factors and how difficult large scale storage is. If solar panels have a capacity factor of around .25, which is what we're seeing in real installations worldwide, then it is necessary to overproduce by at least 4x and store it somewhere for off-peak solar production hours.

It's even worse if there is not other dispatchable generation available unless people are willing to accept periodic blackouts.

We're in the process of building out a combined solar and battery installations in Guam, which is about the ideal case with predictable weather, predictable load, little heavy industry and low potential for load growth. It'll enable them to retire all their old fuel oil generators, but they'll be keeping the diesel/LNG plant for at least the next 30 years even if they only run it a few days worth of time every month.
Absolutely. And the point of a government is to protect people from predatory contracts and agreements that individuals really can't refuse.
Just as a clarification, much of what you mention has only changed in the last year or so. For a very long time gh-pages branch and Jekyll were assumed (you couldn't even use plugins with Jekyll). Custom domains weren't free. SSL wasn't free. Github is doing great stuff but it has taken time to evolve into the all free all you can eat buffet you see today.

i'm back too late to edit; I'll just double-reply. These two functions take a foreign key and a function to retrieve the data you're after and return you a dataloader with the correct indexing applied. Quite nifty, and you'd need the equivalent to both of these eventually.

const oneToOne = (foreign, fn) => new Dataloader(async (keys) => {
const results = await fn(keys);
const index = {};
for(const result of results) {
index[result.get(foreign)] = result;
}

return keys.map(key => key in index ? index[key] : null);
});

const oneToMany = (foreign, fn) => new Dataloader(async (keys) => {
const results = await fn(keys);
const index = {};
for(const result of results) {
const foreignKey = result.get(foreign);
if(!(foreignKey in index)) {
index[foreignKey] = [];
}

index[foreignKey].push(result);
}

return keys.map(key => key in index ? index[key] : []);
});
By "fall of Rome", do you mean the events ending in 476 (https://en.wikipedia.org/wiki/Fall_of_the_Western_Roman_Empi...) or the events ending in 1453 (https://en.wikipedia.org/wiki/Fall_of_Constantinople)? Both seem difficult to connect causally to the weather events of 535-536.
I understand the same, but remember that this is a city government that built this app, not a private company. The app belongs, by rights, to the taxpayers who funded it, and for the city (or their contractors) to be actively working to prevent them from building a better version of it is clearly wrong. Publicly-funded applications should be required to be open source (barring national security concerns), but at the very least they shouldn't actively prevent open alternatives.

You have obviously never owned chickens. Chickens make a sport of pooping where they should not. Eggs, food, and drinking water are all fair game.

If you were thinking like a chicken, you’d see that it’s inevitable: at some point in time, the egg is under the butt. One of the most important rules of being a chicken is to make sure that any clean thing under the butt is immediately pooped on.

The only known exception to this rule is other chickens. I’ve never seen a chicken poop on another chicken.
The thing is, if you leave it up to the companies to look after these people, it’s going to turn ugly every time. It should be the governments job to make sure everyone has a baseline level of life quality.

After the address is safe, put the 3 wallets in physical trezors stored with different banks. Also use the same, but very simple passphrase that you 100% don't forget (do

The cost of this setup maybe $500/year, but at $40k it's worth it.

By contrast this binary search tree code I wrote in OCaml seems to have worked as soon as I got it to compile, although its worst-case performance is pretty bad, and, unlike the much longer hash table code, very likely:

let rec getp k = function `Empty -> None
| `Node(k1, v1, x, y) ->
if k1 = k then Some v1 else getp k (if k < k1 then x else y)
and putp k v = function `Empty -> `Node(k, v, `Empty, `Empty)
| `Node(k1, v1, x, y) when k1 = k -> `Node(k, v, x, y)
| `Node(k1, v1, x, y) -> if k < k1 then `Node(k1, v1, putp k v x, y)
else `Node(k1, v1, x, putp k v y)

And it's about a third the size of the hash-table code. OTOH I spent the last hour writing it.

With four more lines of code it's also a sorting algorithm:

and dictofp = function [] -> `Empty | (k, v)::xs -> putp k v (dictofp xs)
and itemsp d = let rec iter d tl = match d with `Empty -> tl
| `Node(k, v, x, y) -> iter x ((k, v) :: iter y tl)
in iter d []

Look:

# List.map (fun (x, y) -> x) (itemsp (dictofp (List.map (fun x -> (x, x)) ["this"; "is"; "a"; "list"; "of"; "strings"])));;
- : string list = ["a"; "is"; "list"; "of"; "strings"; "this"]

Of course the same comments about worst-case performance apply...
I was just explaining to a coworker that their RAID5 rebuild is likely going to over a day, during which time they shouldn't even think about any I/O intensive activities like snapshot merging in VMware.

Because Windows is a (very broken) Micro-Kernel system which did very little changes to it's kernel (as far as I know) in the last many years, in difference to that Linux is a macro kernel with constant changes and improvements to it.

Are the improvements worth the cost? I don't know.
(For server applications likely yes, but for desktop likely not).

What I do know is that there are clear benefits of micro kernel architectures, even if they are kinda messed up (for a micro kernel) hybrids like windows has.

Lastly the way the kernel API's are designed can also make a major difference independent of the rest. Honestly the Linux kernel API feels much more raw then the windows API, but I only have every written a single dummy driver for each platform and that was quite a while ago.

It is, indeed, a valid an interesting opinion; but, given the situation, this might not be the exact time and place to feel the need to express it.
These are not abandoned salt mines, they are deliberately created caverns in salt domes. The cost of creating them is included in the capital cost ($1/kWh capacity).

Hydrogen could also be stored in depleted gas fields and in deep saline aquifers. The storage capacity available is more than adequate.
Then our transition to solar + wind needs to include the cost of installing a septic tank and water reservoir in every household. And a thermal battery for heating. And an electric battery for lighting. And all the other things we'll need to do to accommodate an unreliable energy grid.

There’s a rapidly expanding shell of photons 1-2 light years thick that perfectly capture the events on Earth during that time.

Some portion of those photons are heading directly towards a point in space where the will intersect one of the millions of black holes estimated to be in our galaxy.

Some portion of those photons will arrive along a trajectory just outside the event horizon, where their path is bent approximately 180 degrees.

Some portion of those will, at some point in the future, be intercepted by our planet earth...or hopefully an array of telescopes trained and synchronized in such a way as to allow us to reassemble a coherent view of a past earth.
What a myopic take. The world just experienced one of the most seismic cultural and behavioral shifts in human history on a scale that's probably never happened before and the vast majority of people fell in line without too much complaint.

You rebuild your build cluster with what image? Where do the binaries there come from? And what machine rebuilds the machines.

Securing the machines themselves is a process of adding up always decreasing marginal gains until you say "enough", but the asymptote is never towards a fully secure cluster. That ceiling on how secure you can get is clearly suboptimal.

Besides, the ops people's personal machines have a bunch of high access permissions that can permanently destroy any security you can invent. That isn't any less true if your ops people work for Microsoft instead of you.

I mean, if you remove the concept of a computer, and ask the question "how many letters are in this word?", you are likely going to end up in some highly-contextual conversations--taking into account all of language, culture, geography, and time--with respect to some of these examples... the concept of "uppercasing or titlecasing" has absolutely no reason to somehow have some logical basis like "the number of characters (which I will note is itself poorly-defined even on a computer) remains constant".
Tiered remuneration based on a judged quality metric is one possible approach to this.

Another approach would be to open a specified number of journalist / creator slots and fund those to a living level (perhaps in addition to the consumption metric). As with many other complex work-products, very short-cycle quality metrics tend to be little better than noise. I believe Cathy O'Neill's written or spoken on this.

Clickbait would result in a low revenue tier.

I've fleshed this out in more detail, my proposal is substantially the same as others have proposed, including Phil Hunt (Pirate Party UK) and RMS, whom you may have heard something of recently, as well as mentions-in-passing by Joseph Stiglitz and others.

Why shouldn't it scale? It's not as if it uses any rare materials. The geological formations in which hydrogen can be stored are abundant. The cost estimation should be good, since the technology is just integrating existing components. That's the easiest and surest kind of technology to roll out.

When company A makes the moral choice to do so and B doesn't, 'investors' will favor B in every case. This is similar to how Costco is criticised for having a 'low' margin and 'good' compensation for all of their staff[]. The tens of millions of people not earning a living wage is a failure of policy that is the result of unfettered greed.

[] Costco starting compensation is not a livable wage for the cities most of their stores are in. Their compensation is only good in comparison to the average compensation for jobs with similar requirements.
the IDE section is a bit dated. as a hiring manager, my belief is that IDEs are good enough (and even have collab features that are good in work-at-home-epoch) that it's not an unreasonable to never use/never have used vi/vim/emacs.

If you're doing server administration, not being able to use vi is unacceptable; but these days everything is deployed by container and logging into raw linux systems is not really a thing as much (your company may beg to differ and that's fine).
The pay here is for all you can eat.

You're already paying more for this on a per-household basis through advertising, for lower-quality content (and killing off quality), with no say on the endpoint publisher revenue, through ad-supported media.

Households with higher income would pay more. Households with low income would have access to all the world's published knowledge.

That seems like an exceedingly equitable trade.

Windows NT is not a microkernel - Windows CE was, however.

NT has been shifting towards running more driver-code in user-space, as has macOS as well, especially with UMDF (especially for USB devices) and for graphics drivers, which are historically the #1 cause of BSODs - however just because the kernel passes control to user-space for the bulk of the driver's number-crunching doesn't mean that architecturally the kernel is still responsible for huge swathes of the computer's functionality. With a true micro-kernel there isn't any third-party code in the kernel space - not even a stub.
