YouTube lecture on this by the discoverer, Ryan Williams
Ryan Willaims's paper, "Simulating Time With Square-Root Space
This appears to be based partly but largely on Tree Evaluation is in Space O(log n * log log n)" by James Cook and Ian Mertz (2023 colloqium, STOC 2024 conference).

I'm just a programmer who has spent an hour or so looking at this, so please take the rest of this post with a grain of salt.

I get the impression that Professor Williams's result so far, already a tool for making progress about which computational complexity classes are the same and different, has the limitation of relying on how slow Turing machines are at accessing memory, based on the mention at 18min:50sec into that YouTube Video of how the space savings degrades for a Turing machine with tapes of more than one dimension. If I understand correctly, for such Turing machines, an algorithm with running time bounded above by time T(n) for any input of length n, the space used by this potentially much slower space-saving simulation is bounded by O( ( T(n) + log T(n) ) ** ( 1 - (1/(D+1))) ). I'm using "**" as exponentiation, so the exponent means square root (that is, exponent 0.5) for a one dimensional (linear) tape, two thirds power (exponent 0.66...) for a tape that is a two dimensional surface, 0.75th power for a three dimensional tape, and, so far, no known savings for a tree shaped tape, although I suppose that that three dimensional limit does ultimately apply to real world data storage systems.

Resolving ambiguities in the law is what judges are for. The existing system is all about writing vague laws and then appointing "agency experts" to fill in the blanks without having to bother with that whole annoying democracy thing to change the law. Some people like it that way though, the submitter seems pretty upset at the idea of lawmaking involving things like voting or separation of powers.

It makes me sick to my stomach to see technology used for dystopian ends like this. This is the kind of shit that makes me want to quit my job, buy a shack in remote Montana somewhere and just "check out" from dealing with "society". It's disgusting. Technology should help liberate and empower individuals, not empower progressively larger and larger and more powerful State bureaucracies.

As soon as I saw the headline I thought, "living tissue over a metal endoskeleton, what could possibly go wrong..."

Obama's falsehoods also spurred a lot if skepticism on politics.

When conservatives riot, it's an "attack", "coup", "insurrection", "threat to our democracy" and so forth, but when liberals riot, like the BLM riots that went on for months, causing vastly more deaths and property damage than January 6, it's a "peaceful protest".

If he wants to go with a car analogy, an iPhone is like a car where opening the hood requires a key that's only available to the dealership mechanics. It keeps clueless users from messing around in there, and protects the manufacturer's income stream. Android, on the other hand, is like a car that lets end users and third party mechanics open the hood and install potentially non-OEM parts in there.

Which of the three will be making the GE minigun?

The rejecting of climate change is pretty easy to account for. A lot of people use climate change to push whatever their personal agenda is:

The climate is changing so we need to...

• Massively raise taxes
• Adopt a socialist economy
• Become vegetarians
• Abandon privately owned vehicles
• Switch to more expensive energy sources

Instead of debating all the kooky non-sequitur solutions are being proposed in the name of climate change, it's easier to just throw the ball back in their court by questioning whether the climate is even changing at all. If debating an actual climate scientist, this might not work very well, but when confronted by people who know little about science and are just using it to lend urgency to their pet cause, this is effective at shutting down their rant about how we must do such-and-such in the name of global warming.

People do this sort of thing in other areas as well. For instance, when faced with someone proselytizing religion, an agnostic might not want to get into some long discussion about what concepts of the divine they are and are not open to considering, and instead just say they don't believe in God at all, even if their private views on spirituality happen to be more nuanced.

Sometimes people take a hard line position just to shut up people they don't want to deal with.

Having no headphone jack (which I use every day) makes this a downgrade not just from my existing phone, but from the first-gen iPhone I had over a decade ago. Sure, you could use a dongle, but why?

The lack of a Bixby button is lame too. Bixby itself is useless, but having a remappable physical button is very handy. I use the one on my Note 8 to turn the flashlight on and off, much quicker and more convenient than doing it through the GUI.
