At a glance he assumes the best practically achievable efficacy for a photovoltaic panel in a solar farm is 10%:

http://www.withouthotair.com/c6/page_41.shtml

>If a breakthrough of solar technology occurs and the cost of photovoltaics
came down enough that we could deploy panels all over the countryside,
what is the maximum conceivable production? Well, if we covered 5% of
the UK with 10%-efficient panels, we’d have

This paragraph is titled "Fantasy time". So before I start the criticism, I would like to thank him for clearly debunking fantasies about hydro and geothermal, where aside from ground-source heat pumps and sparsely populated mountains, they are simply too small. Photovoltaics are the largest source of sustainable energy by far, so the results of an overall analysis will be heavily dependent on the treatment of solar panels.

At the same time, I think it's practical to assume that humans will aggressively innovate the properties and production of PV panels, because the potential value is so large. But I'm going to stick with existing technology. The Agua Caliente farm in Arizona:

https://www.solarfeeds.com/mag/solar-farms-in-the-usa/

uses CdTe panels from First Solar which are currently manufactured with about 16% efficiency:

https://www.firstsolar.com/-/media/First-Solar/Sustainabilit...

As such, describing solar farms as a fantasy, and upper bounding the efficiency at 10%, when there are existing installations built with solar panels at 16% efficiency, seems too pessimistic. Looking ahead to other technologies, perovskites, considered a low-cost option, were recently pushed to 25%:

https://www.pv-magazine.com/2021/04/06/unist-epfl-claim-25-6...

and Alta Devices demonstrated 29% efficiency with a GaAs thin-film before a buyout by a Chinese firm led to a class-action lawsuit filed by disgruntled employees:

I also take issue with the assertion on page 115:

http://www.withouthotair.com/c19/page_115.shtml

>most countries will be in the same boat as
Britain and will have no renewable energy to spare

A glance at a map will immediately show the viewer that Britain is one of the most poleward and densely populated countries in the world — a worst-case scenario for solar electricity. Even Japan has the benefit of sitting significantly further south.

That would be a nice optimization. Here's what Python does

0 LOAD_FAST 0 (x)
2 LOAD_CONST 1 (1000)
4 COMPARE_OP 0 (<)
6 POP_JUMP_IF_FALSE 18

8 LOAD_FAST 0 (x)
10 LOAD_CONST 2 (1)
12 BINARY_ADD
14 STORE_FAST 0 (x)
16 JUMP_ABSOLUTE 0
18 LOAD_CONST 0 (None)

Python's VM is very slow, but note only one arg per op and the compare + jump are not fused.

BTW, if we're considering "advanced" optimization might as well elide the whole loop :) EG https://godbolt.org/z/n3GznqKsM

Freud would say the ego is the mature part of your mind that reconciles archaic demands from the undeveloped id with reality.

In pop culture ego is conflated with what Heinz Kohut or other modern psychoanalyst would call narcissistic disturbance and has to do with instability of the self-image. Even high functioning people teeter on the edge of feelings of grandiosity and worthlessness.

It is not a ‘big ego’ but an undeveloped ego.
Getting all the way back to the 70s took a couple minutes of patient tapping on my phone, only to get told I have NAN left. What a let down.
You should compare apples to apples. Not all societies are alike, and there are huge variances in population density, temperatures, style of living, etc. between different countries ( e.g. places where people share food and ear with their hands vs places where most people live alone in houses vs places where whole extended families share the same house, etc. etc.). Sweden fared drastically worse than its neighbours which are IMHO the most apt comparisons. It has 7 times the death rate of Norway.
Which is probably why he wrote "some regulations," not "completely and entirely 100% perfectly regulated."
Yeah. The reason we’re running a lot of our own open source stacks is that getting anything officially approved has to go through multiple layers of bureaucracy and approvals.

Getting approval to throw an open source project some money is likely to be even crazier (probably not a concept they ever imagined).
They are paid for in blood. For example, when workers in Collumbia went on a strike, US government got involved, decladed the strike 'communist' and 2000 people were massacred.

> A lot of NFTs do use Google Drive or Imgur or whatever. However, I can promise you that one of the first things people do when making sure they are not rugged (crypto-term for scammed) is to make sure it’s not possible for the author to suddenly delete or change the image.

I'm curious about this point; if the only thing stored on the chain is a URL (including Drive/Imgur) then there's no possible way to actually preclude the content from changing right?

It actually does seem very weird that people aren't at least putting a #sha1= in the NFT URL to be able to verifiably know if the underlying content did change.

A haiku from the book "Portraits of Edo and Early Modern Japan":

"The son of the third generation writes ‘Furnished house for sale!’ in beautiful Chinese-style calligraphy."

It's the same idea: the first generation builds the business. the second enjoys the benefits, but remembers the struggle and maintains it. The third generation only knows the luxury and lets it go to ruin.
Yeah, Tables are a challenge in general. The trouble with them from an editor perspective is the range of desired options and control (Many each at table, row, cell level) is fairly vast.

I'm currently in the process of building a new content editor which I'm hoping would provide better opportunities to make such controls more intuitive.
You are arguing a straw man though, nobody is talking about standardization, we are talking about transparency.

If you as a manager can justify the difference then having the salary transparent shouldn't be a problem. If you can't, then there's a problem.

If you are the one receiving the salary, I don't see why you should have to defend yourself anymore than we have people"defending themselves" for living in a nice neighborhood. It simply doesn't come up. Just point to the manager/employer and say "ask them"
I haven’t read the article because of the paywall.

Like most people I’ve spent thousands and thousands of hours getting good at something that employers pay me for. Outside of that, I’m no smarter at anything than any other person. And there is no way for me to spend thousands of hours learning what the best medical treatments are, how to make the best financial decision, the best way to raise kids, hire to work and manage teams remotely, etc.

The only way I can figure out how to deal with all the communications is to listen to experts. Why would I listen to anyone else who hasn’t the spent thousands of hours learning to be an expert? Obviously this doesn’t work perfectly all the time.

The problem seems to me we listen to our tribe/group/friends knowledge, even though the world has gotten too specialized for most of their ad hoc knowledge to be useful.
I wouldn't exactly call electroshock therapy an "input of information"

The same way deep brain stimulation is not an input of information. They're just attempts to modulate neural oscillations in order to alter behaviors and thought processes

To be honest, we don't understand memory itself well enough to build a device for information input. Even our output devices are incredibly blunt and primitive.

Not to say its impossible, people are working constantly on learning how the brain stores information but it doesn't have the sort of funding that cancer research has, so it can be a bit slow going. Also not to say that throwing money at it would solve the problem overnight, the brain as a system is absurdly complex

For the wealthy when people refer to growth versus consumption the context is almost always against the return generated from their portfolio, and the two are separate figures. That "4% growth above inflation" does not include what the capital owner is drawing for his own income. It's almost certainly more like an 8% - 10% return gives 3% to taxes and inflationary pressure, 3% - 4% for income, and the rest to growth.

And, yes, it's quite easy for the wealthy to get investments that return 7% - 8% with low to modest risk of loss. It's much harder to get more than that, but it's not difficult to generate substantial returns from even a modest portfolio in the low 7-figure range.
You can feel that it has nothing to do with the ecosystem or its norms, but it happened in the Ruby ecosystem right in a rather important foundational library, and anecdotally it does feel like it’s a problem that recurs over time. That doesn’t mean there’s a good solution. You can’t just upend the defacto attitude of an ecosystem at will.

> How should this be handled? Should a "good" ecosystem vet every single change in every single library that gets updated? Or should there be no libraries and only stdlib instead (wait, I think I know a compiled language which did just that for quite a few years, let me think which one that was again...)

This isn’t really about Ruby vs all compiled languages, I mean, Brainfuck is a compiled language and that doesn’t mean I was endorsing Brainfuck to replace Ruby. However I would certainly endorse Go to replace Ruby. Rust too, although using Rust to do web development stuff feels like using a nuclear warhead to open a door.

Anyway, the reason why types is relevant to this discussion is because types are contracts that are statically enforced and the break that occurred happened due to a contract change. This change illustrates that even if you do have types it doesn’t guarantee you won’t have breaking contract changes. However, eliminating entire classes of accidental or intentional contract breaks is an obvious win/win. If it was as complex and obtuse as C++, nobody would bother. But C++ isn’t the only game in town anymore for fast compiled strongly typed languages.
> What makes it a blockchain problem is removing the safeguards. If you are saying the blockchain is an immutable record controlled by individual private keys, you are saying that any mistake is permanent. If you allow corrections, you don’t need the expense of a blockchain.

That makes sense. I think the need to correct mistakes, and mistakes I concede will definitely happen, is debatable. There are benefits to some for correcting mistakes and costs to some for it as well. Figuring out whether the benefit exceeds the cost is way out of my scope.

This reminds me of another problem that I've I haven't seen mentioned yet. https://www.newyorker.com/magazine/2021/12/13/half-a-billion...
In a fixed supply cryptocurrency like bitcoin these kind of losses will inevitably lead to deflation.

> Moving to a model where access to a private key is all that matters requires similar solutions before you can say it removes the need for title insurance.

You're right, and I was careful not to say "all" of the needs for title insurance.

I think its worth considering the possibility that not being able to correct even that emotionally charged dying grandfather case, and instead seeking recompense between the two parties most directly involved in the crime (the grandfather and me in your example) is OK. For example, I'm now required to purchase a newly minted and desirably worthless "restitution" NFT from the grandfather for the price I sold the house (or the market value, or w/e is fair), or I go to jail. If we try to backtrack the whole transaction, you are now probably being harmed as well. Is that really better? What if we figure this out 10 years after the initial sale, and the property has changed hands 5 times already. Good luck rolling that back.

Edit: I have just started reading the bitcoin whitepaper and at least half of the introduction is about the possible benefits of the irreversibility of transactions. https://bitcoin.org/bitcoin.pdf

it is pretty trivial to retrieve JS code and the hash from the ArtBlocks smart contracts, and save them into a HTML file to run it locally.

probably a more reasonable concern (rather than the on/off chain question) is one of dependencies (some depend on common libraries like p5) and possible incompatible changes to JS and/or browser spec in the future. At which point emulators may need to be created to continue to display this work.

Generally, the burden of maintenance for AB pieces is quite low and archivability quite accessible, relative to many other digital real-time artworks in museums and galleries today.
FWIW, you aren't (arguing a tangential point to me): I didn't say "one of Facebook's servers goes down", I said "Facebook goes down". Companies go out of business or simply get tired of operating product lines constantly. I can sort of appreciate the idea "well maybe by goes down I just meant temporarily", but then I think one needs apply that to the entire sentence: if it goes down permanently, the accounts are no longer usable permanently (aka, "destroyed"); and, if it goes down temporarily, the accounts and data are no longer usable temporarily.
Rather than changing the brain for each individual bit of knowledge, if we can learn how the brain interfaces with itself for that knowledge, it might be possible to keep the new information or skills in digital form and respond to the access attempt. After the initial interface setup, this might be a way to get "instant" new skills, memories, and knowledge.
Few years ago back when I created such bots I had similar idea .

For certain this can't be mainlined. And if we talk about extensions then at least in past extension code didnt have enough capacities to automatically bypass recaptchas.

This would require fake mouse pointer control and it's obviously not one of features that extension api expose.
Do we have enough data to make this much more precise based on personal information? Seems like much of the useful data would be locked behind medical privacy laws but I would love to see one that took into account current health conditions, maybe even hereditary circumstances.

I have negative time left. I beat the clock ;)
10m wouldn't be the house, you live in a normal 300k house and pay no rent, the 40k covers all your day to day expenses, and you don't need to work. In reality you can probably levarage your security and contacts to get yourself a nice cosy consulting job.

Of course you could decide "I have 10m, I'm going to spend it". Thats your choice.

With 10% growth and 2-3 kids you can pass that on indefinitely to all your children even if all you do is a typical middle class office job.

> Which surprised me! I still don't quite understand why.

Because MySQL (specifically innodb) will cluster by the PK by default, while Posgres will not.

Meaning in MySQL, by default, the table will be stored in PK order, so when you insert an UUID at a random location any record which sorts after it has to be moved to make room, for nothing since UUID ordering is not really relevant (at least for the current standard UUIDs).

In pg, clustering is not a property (at least for now) it's an explicit point operation, which is not performed by default. So when you insert a row whether UUID or INTEGER-keyed, it's just tacked on wherever there's free space. The UUID still has to be inserted at the right place in the index' btree which can lead to a lot of cascading changes, and it's more expensive to compute, store, and load than a simple integer (especially 32b), but it doesn't induce an arbitrarily high amount of shuffling in the storage layer of the table itself.
ULIDs are base 32 as well. https://github.com/oklog/ulid
>HH is less likely than H (.25 vs .5), but HT is also less likely than H and by the same amount. HH and HT are equally likely. This extends to HHHHHH and HHHHHT, and so on.

Well, kind of. There are 2^6 patterns with 6 tosses, and only a few of them have some recognizable pattern (are compressible). HHHHHH is the worst of them. It might be "equally likely" to any other 6-toss pattern seen from a fair coin, but it's also a great example to make one suspect a totally rigged (same sided H) coin.

Now, on average a fair coin would have roughly balanced H and T. So the (much more numerous and thus probable) series where H and T are mixed (e.g. HTTHHT..., HTHTHH..., etc...), are more probable than a large streak of H.

>The probability that there will be one T somewhere in the sequence is a lot higher than the probability that there will be no T. That's only because there are a lot of somewheres for the T to be, but only one way for there to be no T.

A, my sentiments exactly!

>But once you have already seen 99 H, you still have precisely zero information about the next fair flip, and there's no way around it.

That's my argument: you don't have zero information.

You know that the next fair flip is random - sure.

But you also have the information that large series of tosses end up balanced in the long run, which is a kind of push (given fairness) towards making a T after tons of Hs increasingly likely.

Why should this be discarded?

Lol well the length of the article gives a good idea of what you are in for picking something like rust (or any other language really) over go. Every single thing in go from the tooling to the standard library is so relentlessly simple and to the point. It also changes very methodically and doesn’t break things. I really wish more languages would adopt this level of “good design”.
As an aside, I really dislike the style of date picker they are using. I always find them so cumbersome.

If you are designing a website/web app please use a html input type=date, at least on more modern devices and provide a fallback for older ones. The UX for date selection in modern browsers is very well thought through.

Apologies for being off topic.

This looks like a great piece of software. I was never a fan of Confluence, but that is more that Confluence, I feel is backwards. Since confluence, the few opinions is has, is reverse. You typically get some kind of set up like Confluence Space is owned by a person, who then adds approved editors. The default should be open editing, then locking down to specific people. What typically seems to happen in confluence shops is that information ends up being organized by TEAMS not by topic. Which is a terrible way to document. This idea of Books -> Pages seems to be more opinionated that would hopefully get people to not make this mistake.

One thing I've noticed (obviously completely anecdotal) in the workplace is the vocality of who's suffering during the pandemic is biased heavily to extroverts.

The demand in the EU and UK Cars for existing models which do not have speed limit restrictions will be healthy.

From my understanding any Newly launched models from 6th of June 2022 have to be fitted with a speed limiter.

Of course the other reasons due to a shortage of second hand models and new models manufactured recently help
With ICE cars soon being banned from being sold in 2030 just eight years time.

So a well renovated, tried, tested and trusted existing model will suffice for many users. While Toyota save on R&D.

Live in the middle of nowhere or no charging point near your residence? Simply want a car which is not as "restricted"? Plenty of customers will have a refurbed non restricted ICE car, even if a 2021 model years later.
