Ethereum switched to proof of stake a while ago. So yes. Hardcore crypto fans don't like it because theoretically it could be subject to the 51% attack. Personally, Ethereum is big enough where

A) I don't think that attack is likely and B) the efficiency gains are worth the risk

Disclaimer: I have Ethereum so i benefit from other people buying it. I do honestly think it's better for the environment.

This theory is very interesting, although the author presents it with too much confidence for such big claims.


In that link:

> The Earth's rotational kinetic energy is about 10²9 J, and the world uses something like 10²² J/year, so you could power the entire world for millions of years before you'd run out of rotational energy.

(my phone somehow has a ² but not a ^9; the first number is supposed to be 1e29)


Here are some Unicode exponents for your future needs: ⁰¹²³⁴⁵⁶⁷⁸⁹


What about dozenal?


It's really not very common in typical online writing about science and engineering, but I'm happy to share ᴬᴮᵃᵇ and ₁₂ in case they're also useful to anybody.


Wh....why?


On my side, a combination of:

- I'm likely to return back to some of them. I might not know which ones. Typing in the address bar brings them back fast and the page does not need to be loaded again. Having the tab already open is also a strong signal that this is what I'm looking up.

- no noticeable slowdown anyway, Firefox is actually quite efficient.

- I don't care for taking the time of closing them progressively. It happens that I will close them all at the same time at some point when I feel like I need some clean up. Usually when I'm done with something.

- I think I learned to mostly ignore this part of the screen. Everything happens in the address bar.

In short, it's a combination of intentionally leaving tabs open so I can go back to them later without reloading the page, and not wanting to spend the time to manage them.

I usually have under 100 tabs open though, often even fewer.


Same applies to thousands of them, the "close everything" time just happens later in that case. I usually clean them up once Firefox starts slowing down, which is at tens of thousands.

With a good UI the unused ones just don't bother you anymore anyway until you scroll or filter them. They show me my train of thoughts without having to consciously organize anything. Unused tabs get unloaded from RAM anyway, so the cost of keeping them open is minimal.

A few years ago there was a version of Firefox that didn't slow down and opened quickly even at tens of thousands of tabs, but unfortunately it quickly regressed, so throwing everything out periodically is still inevitable:)


They probably don't know how to close tabs.


I've never had that bug, although I'm on chrome.


I've definitely gotten it with chrome (and chrome-based browsers), Safari's apparently affected as well, although it seems worst on firefox. Depends on what you paste. Seems to be some unicode in Chrome, vs anything in FF.


Chrome really needs to introduce a extension denylist. The effect of malicious extensions would be less if you could exclude banking and other sensitive websites.

The current Allowlist is not sufficient because some extensions need to work across most sites.


There's a lot of systems that are simpler, easier, and in my personal opinion, more fun than d&d. For example, FATE. The star wars RPG is pretty good too. Tabletop games can also vary a lot in quality depending on the group and the GM.


Less fuel is better for the environment. That should be counterbalanced with safety, which they did - even with a bug and a heavy plane the plane still took off safely.

This means they are also leaving a safety margin of fuel, even though that costs extra money.


A tail strike is not a safe takeoff! That nothing happened doesn't mean there was no danger.


AREPL uses a debug first paradigm. It's not step by step, but it does give you access to your variables as you code.

It's free and open source. Let me know what you think: https://github.com/Almenon/AREPL-vscode


Only ~13% of CS grads are women last time I checked. So yes, the filtering is happening, and it's before the candidate even looks at the job advertisement.


Studying history is extremely important for doing your civic duty as a citizen and voting.


This would make sense if they teached recent history, which was at least not part of our curriculum and not to mention even if it was, it would be even more "regulated"

But no, at least in where I lived (Turkey) the history classes are ancient history, then some Turkish civilizations in Anatolia, Ottomans and early Turkey history. Then we have like a 60-70 years of empty space. Is this different for other countries?


So is quantitative thinking, in fact I think it’s more important.


You can get that without calc
