The preprint is in math.AP (Analysis of PDEs) alone. Most of the preprints by the three authors are found in math.AP, give or take some in math.CA (classical analysis & ODEs) and math.DG (diffgeo), with significant crossposting into math-ph and gr-qc.

There is only a minority of <https://arxiv.org/list/gr-qc/new> that is crossposted into math.AP, but even fewer <https://arxiv.org/list/math.AP/recent> find themselves also in gr-qc.

> Sad side note

Amusingly, Alan Coley's [open problems in] "Mathematical General Relativity" <https://arxiv.org/abs/1807.08628> is only in gr-qc (§2.4 is relevant to the whole discussion here) and although he posts almost all his papers there, he is very much a mathematician <https://www.dal.ca/faculty/science/math-stats/faculty-staff/...>. (The earlier Chruściel, Galloway, Pollack "Mathematical general relativity: a sampler", citation [9] in Coley, <https://arxiv.org/abs/1004.1016> is in gr-qc, math.AP, and math.DG.)

Postdoc research? How did they avoid contact with mathematical GR? Hyper-hyper-specialization into an area where one diagonalizes almost as often as one breathes or spends all one's time in Cactus? If their shelves are surprisingly barren, they are liable to get thrown a copy of Wald, John M. Stewart (CUP 1991), and/or any of Choquet-Bruhat's books (esp. OUP 2008), and then Wald again.

The difference between mining Bitcoin and a "traditional" industries is that mining rigs can be switched off in a matter of seconds.

A beautiful example was "snowmageddon" in Texas. Or last week's power dip. In both instances the energy grid was not able to deliver the amount of energy that households need (in the first instance for heating, in the second for cooling) and in both cases the Bitcoin miners were switched off, thereby making a lot of MWh available for different locations.

Mind you: the miners only want to use cheap energy, and an electricity producer wants a stable need on their network. So this is a beautiful win-win situation. It's exactly creating the elasticity that the power grid in the 21st century needs.

I've been following this company for a few years now. It is not fake, just bad advertisement I guess. My biochemistry professor (and as far as my textbook understanding of biochemistry goes), the process which they use to produce the protein makes sense.

Wether it's something economically sustainable, or something that might become "socially accepted" or something, I don't know.

If I have to be picky, I'd rather eat a synthetic protein made with genetically modified bacteria than genetically modified cockroaches powder. You wouldn't probably notice a big difference anyway.

I don't think this is the only reason though. (preclinical) Bioscience experiments can be extremely expensive and yet they remain pretty concentrated at universities, for better or worse.

I don't know about the state of funding in protein folding specifically, but knowing about the kind of funding that some other high profile bio labs can get I am skeptical that material resources were the main difference between alpha fold and what the prior academic lit could do, for example.

You can change the keyboard layout per language. I type mostly in French (on an otherwise English language phone) and use French in QWERTY layout.

For the special characters (é, à, etc), I long-press and choose whatever I need.

Since I hate typing on the phone, I quite like using the suggestions, especially for words with multiple special characters.

TRISO fuels may have higher burnup, but they also have large dead volume in the fuel elements. The fissionable material is surrounded by barrier layers, and these encapsulated particles are embedded in a non-fuel matrix. The volume of spent pebbles will I think be considerably larger than the volume of spent fuel elements from a conventional reactor per unit of produced thermal energy.

Your information is incorrect.

"Avoiding spinning up new processes" is incorrect characterization of s6. Processes are not a scarce resource; spawning a process is not a costly operation in the context of process supervision, even on embedded systems. s6 focuses on optimizing some metrics that are indeed important to embedded systems, like RAM use and code path length, but "spinning up new processes" isn't one of these metrics.

It is not, and has never been, necessary to learn execline, the scripting language you're speaking of, in order to use s6. execline is used _internally_, and you can also use it in your own scripts if you so choose, but it is not a requirement.

"Sending a polite shutdown signal, waiting for some time, and sending a harsher shutdown signal" is a matter of exactly one command: s6-svc -d. That is precisely one of the benefits of s6 over other daemontools-style supervisors: it handles this sequence natively.

I welcome fact-based criticism of s6. I do not welcome FUD-based criticism.

"What makes roads safer is better engineering, better technology, and education."

In my mind, education is by far the biggest issue today. Most people have no clue about vehicle dynamics, or they think bad stuff only happens to other people. Like you said, speed itself isn't necessarily bad. But people speeding around a turn have near zero chance at avoiding a bad outcome if there's some obstacle in the road - they've never tried to slam the brakes on while turning, and/or they think there couldn't possibly be a disabled car, a person, a deer, etc around that blind turn.

Technology has certainly helped improve survival. I think it is helping to prevent some accidents to too. I think we still need some refinement on some of the newer tech and/or better education on how to use it. I think sometimes people rely on the tech too much, like autopilot. I think many people aren't fully ready to take over if autopilot has an issue. I had two friends using autopilot tell me it slammed on their brakes at an overpass shadow. Now, they didn't go into detail about the time to recovery, but I'm guessing for at least some people it's significant if they aren't paying attention because they trust the system too much.

As for engineering, there's probably a lot that could be done. I haven't seen many changes to road design beyond adding stop signs, lights, textured pavement on turns, etc. I'm guessing it's cost prohibitive, similar to how educational changes are socially prohibitive.

When there are major power outages that take down networks how will cashless payments be made?

I've seen stores stay open in a power outage with clever uses of extension cords running out to vehicles, enough to power the cash register and a few led lights. These stores were able to easily sell groceries (before they perished) and non-perishable items via cash.
Payments have spiked 50%+ in about the missing time period thanks to rate raises. And that 1.5 times average about in line to well below the delta in money printing average in the same time period.

The story here is NIMBYism, California Real Estate, Tech, and the "housing shortage". Your data is honed in on the Nation Average and emphasizes the 2020 spike in prices that reflects an exceptional supply constraint in conjunction with a massive(exceptional) migration driver and breakout money printing(none of which speak to a localized housing shortage which would interface conflicts with NIMBYism in a material way). NIMBYism is primarily focused on affluent communities, so low income communities and national averages are fairly irrelevant in arguments pertaining to such(most communities can't lawyer up for long property battles). Most arguments conflating NIMBYism to other issues are calls for Government housing support.

Unfortunately most of the data I'm working on is derived from Zillow, which is specific to markets, lagging, and not open for export. Look at the Zillow charts of the average homes in most of the real NIMBY markets(San Mateo, San Francisco, Orange County, Marin, Etc) and you will see a fast dropping Zestimate that is well above the average transaction prices actually conducted in the last few weeks. All while supply is accumulating well outside averages. Debt bubbles pop fast. This one is the beneficiaries of government pumping debt with low interest rates into homes surrounding the growth companies that rode its wave. Tides out, so boats are hitting the shore.
When I read about the 30,000 cycles, I can't help but picture a mechanism which performs a "perfect" opening/closing cycle with equal force distribution.

I don't know about the percentages, but I think the majority of people who would see a tax cut are those who bought property in the past 10 years at inflated prices. The people hurt the most will be those who've been living in the same home they purchased 40 years ago, and are clinging to their tax assessment that's orders of magnitudes behind what the current assessed value would be.

There are ways to fix that too with gradual phase-ins, not allowing people to pass their tax assessment on to their heirs, etc. But anyone who stands to inherit property will vote against such a move, and most people who will be passing along that property will vote the same way.

For me cursor placement fails like 40% of the time. I guess because I didn’t get the vertical position correct? I have the insertion point in the place I want it, release, and the cursor flies back to its original position. It is pretty irritating. Especially the second time in a row.

I was on a trading floor 2 weeks ago and every trader workstation I saw had an Excel session running. Of course they were also running bank approved production systems, but every one of those have an Export to Excel option. Traders like control and don't like to be held hostage to IT groups that "take too long" to write code.
Microsoft has been piling tons of money into Excel in recent years to make it even more useful. Dynamic arrays are a game changer and they have recently released a slew of new array functions to leverage off of that.

- Refuse to print/read uid_t that are outside intmax_t range

- Use an autoconf test

Throwing in my few pennies regarding my experiences living in cities.

Having lived in a few well known places, with different urban planning characteristics:

- Tokyo. Very praised for its successes, and there are quite a few: extremely liberal zoning (it seems), based around mass transit rather than cars (great!). Despite the small living space sizes for some, reportedly still very affordable, wide low/med/high density options for at various price-points spread all over. On the other hand, rarely worth having more than prefab buildings (earthquakes), masssssive sprawl, and legendarily horrendous commutes for those living in the suburbs. More than half the city is really quite ugly, grey and concrete.

- Berlin. Lots to like based on good previous planning decisions, and that war-time destruction and reunification somewhat provided opportunities to modernise. The city centre is mostly medium-density 5/6 storey apartment buildings. This seems to be a great sweet-spot that packs in a lot of people, but still leads to a strong community feeling in neighbourhoods. Even in the city centre, extremely green, and very accessible nature thanks to effective public transport. On the other hand, the last few decades of success may have had a lot to do with its historical anomalies, and now that it's normalising in lines with other similar cities, feels like these benefits have been drying up.

- London. Creaking under the legacy of its historical city centre. Planned under the assumption that of course everyone is living in multi-million Pound townhouses in Zone 1. Everyone else is SOL; the rest is low density suburbs with transit that forces most journeys to be via the centre, since there is no outer ring line (great in Berlin, not so great in Tokyo). Seems hardly any medium density: endless neighbourhoods of single family homes, or skyscrapers.

Anyway, none of this is new. It seems pretty clear that the political inability to fix these issues are a massive drain on economies already, and this will only get worse in the future with increasing urbanisation. Frankly, seems the only solution is building entire new cities. Asia has certainly benefited from this in the 20th century...

My thoughts
(I own iOS devices and a M1 MBP.)

Windows 11's window management is brilliant, nothing comes close out of the box (of course i3/sway/etc. can be customized to match it). Windows tablets as laptops are generally more usable than iPads as laptops due to stuff like multi-user support, filesystem access and much better window management. As tablets (media consumption + creative work like drawing) iPads are better.

This foldable device can be a nice primary machine while an iPad can't replace a laptop for most users. Macbooks are of course fine devices, but I think folding can become a nice feature when it matures.

Only because Apple's track record so far is a lot better than Asus' or other OEMs in terms of not adding novelty or gadget-y features to their pro products.
What's usually missing from these comparisons is how long people are actually using the phone and how they handle the battery.

Mine is an iPhone 7 I bought refurbished back in February 2017. This phone is likely to have seen less use than a friend of mine's phone bought at the end of 2021. It spends 95% of its life connected to a power source (even when I actively use it), so I expect the battery to last quite some time.

Can you disable telemetry entirely? Can you use an iPhone without an iCloud account? Without connecting to Apple servers? I believe not, but would be happy to be proven wrong!

There was also this comparative study of iOS/Android telemetry: https://www.scss.tcd.ie/doug.leith/apple_google.pdf

It concludes:

> We find that even when minimally configured and the handset is idle both iOS and Google Android share data with Apple/Google on average every 4.5 mins. The phone IMEI, hardware serial number, SIM serial number and IMSI, handset phone number etc are shared with Apple and Google. Both iOS and Google Android transmit telemetry, despite the user explicitly opting out of this. When a SIM is inserted both iOS and Google Android send details to Apple/Google. iOS sends
the MAC addresses of nearby devices, e.g. other handsets and the home gateway, to Apple together with their GPS location. Currently there are few, if any, realistic options for preventing this data sharing.

My post isn't clear, in that case. I'm not claiming it's a literal reflex :)

A top-flight tennis player is responding extremely quickly, and extremely accurately. Deliberate, planned action is not happening. It's something else. It's not a spinal reflex, it's something that involves parts of the brain to very rapidly 'orchestrate' a highly complex musculoskeletal dance.

The raw processing necessary to coordinate that dance cannot (in my understanding) be achieved by familiar neurological pathways -- observing, planning, deciding, coordinating. The planning and deciding aspects are bypassed. Only a tiny fraction of the observing aspect is used, such as the moment the other player strikes the ball (because the ball then moves too fast to react to). Some form of prediction happens. Then a number of 'movement primitives' seem to be selected and orchestrated. Ideally, the whole system is tweaked in real-time based on feedback (visual, proprioceptive) regarding whether the goal was achieved -- i.e. did you return the serve well.

It's wild.

It's also possible I'm mis-remembering and mis-interpreting some of this stuff :)
