> Police watchdog investigators then found evidence that the Met’s treatment of Shao, one of the last protesters in Tiananmen Square in 1989, was influenced by pressure from Beijing to ensure Xi was not “embarrassed” by protests during his visit.

I'd say no countries dare to not please China. Blatantly attacks the people who risk their lives to say.
in reality all it took was one guy dedicating a couple of months of exclusive work to it

This is wrong. Many professional mathematicians attacked the problem, and many useful discoveries were made before it was proved. For a brief summary, see https://en.wikipedia.org/wiki/Fermat%27s_Last_Theorem#Early_...
So what was the ultimate negotiated price your insurance paid? Likely there was a 70%+ discount applied.

Related projects to look at for ideas, and a handhelds opportunity...

Scwm is an old but interesting X window manager using Scheme: https://en.wikipedia.org/wiki/Scwm

Rwind is a more recent related project, in Racket (a big Scheme variant), and probably needs a developer to build higher-level features: https://pkgs.racket-lang.org/package/rwind

Although it's in Haskell rather than a Scheme, Xmonad has been solid as a daily driver, and presumably is worth looking at for a relatively modern WM implementation (compared to trying to figure out the whats and whys of how Fvwm works): https://en.wikipedia.org/wiki/Xmonad

Also the popular tiling window manager i3, and how its Wayland drop-in, Sway, work: https://en.wikipedia.org/wiki/I3_(window_manager)

If you make a Guile-based WM that does a good job of smartphone-like one-app-displayed-at-a-time window management (like the old Matchbox WM did), with status bar and popup keyboard, then I would like to use it on GNU/Linux handhelds, and might be tempted to switch the entire project from Racket to Guile: https://www.neilvandyke.org/postmarketos/
This is one of those rare posts on hacker news that I'm qualified to reply to (I normally lurk - had to make an account). I work as an expert in power system operations for a national grid.

So with that disclaimer out of the way, I want to say that this research is incredibly misleading, particularly when it is presented as 'ways to avoid blackouts'.

What they present is an 'adequacy' model. That means, essentially running an accounting simulation of energy in and energy out. It is what power system engineers refer to as 'copper plate' model, in that it replaces the entire transmission and distribution network with a hypothetical infinite conductor where everything connects to everything else. Such a copper plate would never have a 'blackout' as long as Energy In = Energy Out.

Therein lies the bullshit. Blackouts don't occur just because Energy In =/= Energy out. They are incredibly complicated and nuanced, and often result from multiple minor events cascading into something larger [0].

You need, at a minimum, a steady-state power flow simulation to be able to analyse power system security. Particularly when assessing low inertia power systems (such as the systems proposed in this paper). The fact that the word inertia is not mentioned in a paper advocating high-penetration of wind and solar is a massive red flag (I'm talking, Moroccan palace style large).

I laughed out loud when I read "LOADMATCH runs quickly (e.g., ~2.6 min for a 5-year, 5.3 milliontime-step, simulation on a single Nehalem 5580 3.2 GHz processor)" knowing that it takes around that time to simulate a load flow on the pan-european grid, or around that long to do a basic security assessment on a single country's grid.

I worry that policy makers will be 'informed' by this research and will unknowingly sweep a lot of complexity under the rug until blackouts become more common.

> large hackers are perfectly fine with woefully inefficient feature-packed apps for their "primary" apps like their IDE

well, even the most feature-bloated IDE loads faster than GMail on my computer (before anyone asks, I'm on gigabit fiber)
I’m sure that’s true.. for some definitions of “enjoy” that involve no pleasure or happiness :)
Yep. Unless a company actively engages clients to get product feedback, it's unlikely that the end users even have the clout to complain about app performance until a vendor improves it.

There are times that I perceive the community trying to convince itself that web devs can have their cake and eat it too. That it's not just possible but easier to built performant, accessible and maintainable apps in React/Angular/Vue, when that's just not a universal truth. Sure, those tools may make certain aspects of development easier through the abstractions they leverage, but those also come with a cost (i.e. breaking API changes seem to be in vogue these days).

Ultimately, this part in parcel of the JS community. Aspects of the ecosystem feel so fragile (NPM, framework/lib churn, etc.) that it's easy to be cynical about web app performance.
Do we know that quantum effects will actually scale large enough to realize those speed ups for arbitrarily-large problems though?

Even modern combustion engines are still pretty noisy at low speeds compared to EVs. Especially when starting up or when revving to pull away at an intersection. At < 12 mph they’re not displacing enough air to make a “whoosh”!

Diesel engines, endemic in Europe even in small cars, are particularly noisy.
> There were plenty of people who tackled this problem and who failed to make any headway.

There was also plenty of meaningful progress throughout the 20th century at least, showing that the FLT was implied by other statements which would be easier to prove. Wiles's work was a follow-on to this progress; it's quite misleading to say that it "took" a single guy working over six years to prove FLT.
> I believe under the EU rules, sound is only emitted up to 20km/h (12 mph).

Doesn't that make it pretty pointless then? Collisions below that speed are almost never fatal even for pedestrians.

I feel like it may actually be better for inattentive drivers to hit something at those kinds of speeds and jar them into being more careful in the future (and have their insurance rightfully dinged) than to have their first experience of their not paying attention causing them to hit something occur at a higher speed.
I worry this is going to become new accepted wisdom without being tested fully (it's probably already a Webpack plugin). My questions:

- What about other browsers?

- how big does it have to be to have a meaningful effect? I've seen an example out there with someone demonstrating amazing gains... on their 163KB of initial state. That's not typical. Or at least I really hope it isn't.
The parent’s point is that, if all these things were browser JS runtime features, there’d be no tradeoff to be made. They’d be “free.”

If every JS page in the world today includes the same line of code, isn’t it obviously the fault of browser makers for not making that line of code part of the JS prelude and thereby making it “free”?
Well! I agree with some of his thoughts. I came to notice him recently through social media and do not know much about him.

But his identity politics argument and his equality of outcome is very true. In my country I am seeing the consequence of identity politics and groupism. Everyday lot of people being violent and some time it leads to deaths and lynching.

Another thing in my country is some group have certain quotas (equality of outcome) which leads to degraded products and performance and competent people are being ignored which can contribute much better.

Other than that I find some of his interview thought provoking.

```Yes, it turns out that one of those pieces of paper I signed without question had sold 90% of the shares of Hit Media Inc to his company.```

Not buying this...

His father should have told him that he was taking ownership of his company for the loan. The fact is, the guy loaned him $20K, had him sign "paperwork" and didn't tell him is the issue here -- pretty sure right there what he signed was a loan and sales of 90% of the company.

I've read Siver's stories over the years. Entertaining and certainly one of the Ruby guys to listen too... but this is just a bit of a stretch to say "I'm not mad at my Dad." -- he should have been furious unless he knew and this is just another one of Derek's "stories".

Dad sounds like he wasn't forthcoming with what Derek was signing -- or maybe Derek knew and needed a good blog post?
> For example, to have an element “animate away”: create a new purely-visual element at an absolute location that looks like the original object, delete the original object immediately, and then let the proxy go away whenever it is done animating. This completely frees you from having to worry about the true lifetime of the original object.

The OPs point is that doing this is far more DOM-intensive, and leads to worse performance. It isn't a good solution.
If I had a local group to meet with, then I would be more inclined to do that. And I would likely find more use/support from a local group. It's good you have this option.

One odd thing I got out of group meetings was seeing partly where people failed to live up to their own goals. (a bit of a warning to myself)

If what someone is looking for is actual funding, I completely agree that SuS is a waste of time for about 95% (or more?) of the people joining it.
> Crazy idea: let's reduce that.

If you lived in a hot climate (like India, which is one of the countries TFA referred to as a source of high future demand), then you'd understand just how crazy of an idea that is. (side note: your profile links to a site with a bio claiming that you live in Massachusetts. I rest my case.)

Look, it's not that the idea has zero merit. There are architectures which do a better job at keeping the interiors cool, and incentives could be set up to favor those designs. But such designs are also usually bone-cold in the winter, and you see energy usage pendulum-swing back to high in other parts of the year. Plus, locales with hot weather typically have local architectures with these kinds of "natural cooling" features anyway, so it's usually not anything new.

There's a reason why I think calls to reduce air conditioning to be anti-development, and it's because I happen to live in one of said climates, and there's no way I'd get anything done without air conditioning. Unless we want to keep the underdeveloped regions of the world in poverty, increased demand for air conditioning is simply inevitable.
I think there are only two safe options if your intention is to avoid being assassinated: 1) don't tell anyone, 2) publish it anonymously. If you want to be able to prove to somebody that you're the author, sign the paper and keep the private key offline on a piece of paper.

Yann LeCun: AI is changing the entire nature of compute
I think the answer is "passion". People remember such details in a specific field because they have a passion for it. The same person remembering techniques used in movie making probably know very little metallurgy.

Most people find some topics that just resonate with them and things just "stick" better. It's hard to force it and if you lack that "perfect fit" (or an incredible memory) those details will still be lost once you put the book down. You'll still have the broad strokes which is still very interesting knowledge to have in a conversation.
You won’t necessarily be able to verify it works empirically, even if you can prove so analytically, because it would be a complexity bound that was broken. If I could crack RSA keys for a mere one million times the computational resources used to create them, that would be a groundbreaking result and I would have “broken RSA”, but _I_ still wouldn’t be able to crack any RSA keys at all.
> Keep a running list of meals and their ingredients that your household already enjoys. That way, you can easily choose, shop for and prepare meals.

Great list. We keep a wiki page on our server that contains "menus" for the week along with the shopping list. We are able to rotate those every couple of months (ie: we have a couple months worth of menus that we rotate through) and it is just grab the list, check the pantry/fridge for what we have and get what we need from the store. Super easy.

Recipes do get tired, so we do rotate those out and some new ones in, but the above is the general flow.

We eat reasonably healthy. We can maximize our spend by looking for deals. We don't have to expend too much effort planning now.

Also Andrew Wiles' six years of focused worked fundamentally depended on very deep work that Ken Ribet had just completed, which in turn relied on decades of highly nontrivial work by Mazur, Katz, and others on modular curves and modular forms, which made surprising connections with other areas of mathematics. Finally, Wiles' first announced proof of FLT was wrong, and Richard Taylor collaborated with him to find a correct and quite different proof. (Disclaimer: I published a book on modular forms, and cowrote papers with some of the people mentioned above.)

There are a few reasons beyond pride why the line for when to use paracetamol etc differs among individuals.

Propensity to take or avoid unnecessary medication is something that probably aligns to certain psychological traits, as well as being picked up from parents and peers in childhood. Also, some people suffer more than others in treatable ways (my mother regularly had headaches, I rarely do).

I personally avoid unnecessary medication (not in any active sense, but more like "ehh it's not really bad enough and it'll be over soon") whenever possible and could probably count on one hand the number of times I've taken any in the last 10 years, but on the other hand I have friends who take great joy in having something (or things) on hand for just about any ailment which someone might mention in passing.

One possible reason is that some people weigh the tax on their liver and/or stomach more strongly than a brief temperature. These medications, although amazing and broadly safe, aren't altogether without tradeoffs.

I guess for me it's that I don't suffer very much from the symptoms of minor illnesses, and possibly that I want to save my liver damage for alcohol.
Exactly. Not only aren't people random, they're predictable based on history[0]. Each person could only be asked for one number and they shouldn't even wait perceptibly different lengths of time to be asked.

I think sugar is far worse than caffeine including alternatives like Stevia. Decaf on the other hand depending on how it was made into decaf can also be harmful.

As for competition - due to network effects there are very few competitors to things like Facebook, Amazon and other big tech.

If these were federated services participating in communication built around some gigantic independent social graph - that would enable more competition in terms of UI performance, features, etc. Not going to happen anytime soon though.

Great article that brought back some fond memories of the Sega Channel. As a young teenager when we got it, I was in awe of the technology and wondered how it worked and why something like it didn’t exist for the computer. Not having to tie up a phone line AND it was even faster! Loading it up for the first time really felt like it was magic and world-changing.

Interestingly enough, later on when cable modems came out in my city, you still had to use a phone line for the up channel. The Sega Channel still seemed superior to what PCs had and always wondered how they pulled it off. So, it’s neat today learning how it worked!

The Sega Channel was definitely too late though. The Genesis was old and I swear it seemed like the PlayStation came out a short few weeks after we got it. Of course, that was its own type of magic that felt world-changing when powering it on the first time. ;)
