If someone asks if you can move a big boulder, and the answer is that it is too heavy, it really matters if it is in a location where it can roll down, like on the side of a mountain. In that case, heavy may not be such a problem.

It so happens that for every elliptical orbit, there is a circular orbit with the same angular momentum but a lower energy. The amount of energy excess available from this orbital change is 0.5mv^2*(eccentricity)^2. The moon's orbit has an eccentricity of 0.055, so 0.055^2 or 0.3% of the moons orbital energy could be extracted when changing its orbit from elliptical to circular. That is about 1.1e26 J, more than 1000 times the energy from burning all fossil fuel reserves.

The orbital energy could be gathered by sending a swarm of satellites connected by long cables into a circular orbit around the Earth, matching the period and phase of the Moon. The satellites would be spun around a common axis, like a Klemperer rosette, but using cables instead of gravity to keep them in place. The moon would then pass through the middle of this ring twice each month. Each time it did, the moon's gravity would pull the satellites closer to the center, and the cables would be reeled in. When the moon passed by, the cables would be reeled out again to their original position, allowing for generators to gather the energy. Gathered energy could be used to put more or heavier satellites into place using mass from the moon, making the process rate increase exponentially.

It may not alter the moon's orbit 'significantly', but it is doable with our current state of technology.
"I also had to wear this cloth knee support thing for a couole of weeks after some extra long walking with friend"

My experience with bandages is, only use them when you absolutely have to. Otherwise your body gets used to them and sees even less need to make the knee work on its own.

In general, I am not a doctor, but went through years of working out how to fix bad knees and went from doctor to doctor, operation etc.
(most doctors were actually very bad for anything not routine)

What helped in the end, was establishing a habit of doing special knee exercises whenever possible. And lots of adequate sport in moderation. Climbing and Trampolin may sound crazy, but are actually pretty good for the knees if done on a light level and also walking barefeet helped a lot. In general, trying to get the muscles around the knee as strong as possible, as then the muscles can hold your knee to replace whatever is broken inside your knee.

"Anyway, I tried to exercise, I got an injury, and I felt worse than without exercise, cause something was taken away from me."

And I would be careful with your conclusion, in my opinion you just did too much of wrong exercise. That is bad, yes (and is also what messed up my knees initially). So maybe try to find activities or exercises that are fun, but not too hard. And yes, it sucks not being able to do, what you could do before. At some point I allmost thought I would never be able to run again. And I definitely will never get back to the state of before - but I managed to do quite a lot again. Anyway, all the best for your recovery.

> Does a paper ticket do anything to prevent this?

Ticket inspectors used to mark the tickets so they'd know if someone was reusing a ticket. Originally it would be clipped, then date stamped, and towards the end on South West Trains it was a scribble of biro (or black marker if you were unlucky).

On the occasional trips I take I now use an e-ticket. I have never had the QR(ish) code on it scanned for validity.

Author mentions, but doesn't focus on, 'work being too challenging/not challenging enough'. I wrote a fair bit about it here (with a slightly different focus as name suggests, but I go over original research first) https://incentiveassemblage.substack.com/p/why-is-nobody-ser.... I'm not sure why 'challenge level' is less focused on compared to lack of interruptions - both seem about equally demanding to environment including manages and take similar amount of work to adjust.

Either way, to save you a click, Csikszenthmihalyi research wasn't mainly about cognitive load, because we already had a fair bit of research on cognitive load. It seems insufficient (although I do have my reservations), but addition of complexity of the task and w/e additional issues are happening is pretty solid predictor* of performance. Challenge/skill 'graph' presented can be reinterpreted with challenge/skill on X axis and a parallel flat line above it. Even better, and empirically supported, graph can be seen in first image in the post I linked, but it is a bit much to paint with words.

Flow research is cool, but there are more simple and actionable tools.

*Observant reader may notice that this is because of lack of units, but we do have physiological indicators if one desires to monitor them.
The real problem this guy is encountering is making interactive applications for a web browser is hammering a square peg through a round hole at its core. That's why performance is bad, that's why there is a new framework every other week trying to find a better workflow with better abstractions. There is so much inertia, such a huge ecosystem, many billions of dollars invested in it trying to make it less bad so it's not going away.
When did the Texas government start representing freedom? The current governor and legislature openly pass laws with the express purpose of punishing people and companies that disagree with their ideology. They pass laws seeking to control what women do with their bodies, interfering in medical decisions to the extent that women have had to fly to other states for necessary medical procedures. What part of that is freedom?

The article makes it sound like they don't show the message in this case

> The Passenger Operated Machine (POM), to use the TfL name for the ticket machines, doesn’t show the pop-up for every journey that they can sell tickets for because not every destination accepts contactless PAYG tickets, but those that can will get the message. Over time, as more National Rail stations are added to the contactless payments system, the ticket machines will be updated to include them in the messaging.

Generally asdf shines when you need more than one system installed - say a html or SQL language server that depends on node in addition to python for your main app.

No, but apparently the arts of rhetoric and reason are completely dead. There is a big gap in this blog post somewhere between "a given program is not optimized for a specific use-case" and "we lost our way of developing optimized, efficient, and performance-wise applications".

That’s a lot of words to say “I want to continue shooting myself in the foot, please!”
Your complaining makes out like you’re powerless to stop yourself from using legacy PATs. You’re not. You could just suck it up and spend the time doing the very low effort high reward activity of rotating your keys. There’s a reason why every security posture determination questionnaire under the sun asks about key rotation. It’s because old keys lingering around is a very material security issue in practice.
GitHub emails you when a fine-grained PAT is about to expire. Repeatedly. If you forget, then presumably your actual automations are going to stop working. And to be blunt, if it gets to that point (e.g. you don’t act on repeated emails, or your cron monitoring isn’t such that you’re told about about things failing) then it sounds like you have bigger problems.
You long for increased audit logging (have you actually looked at what’s already available!?). Audit logging is only so useful because it tells you what already happened, and you have to actually either notice that your key has been compromised, or be proactively monitoring your audit logs. Are you telling me that you’ve managed to carve out the time in your day for this, but you can’t rotate your keys once a year?

I have great sympathy for GitHub’s position and have been in similar ones. Your customer’s security is always, to varying degrees, your problem. I’ve got no doubt that this explicit design choice is in response to support requests, and that it informed by their real-world experiences re attack vectors related to PATs. The problem is that every developer always wants to hit the “no, I’m special, let me do this” button.

How Old Are These Keys? Five Eras of Human Progress
$10 = 6% fee; $5 = 8% fee. Both of which are far better than apple’s fees, so that point is a bit confusing.

Chargebacks = customer support. I agree with that, but if you have a B2C business which has any non-trivial revenue (OP is talking about word doc apps, so we’re obviously not talking about indie $2 side project apps), then you would already have CS anyway. I fully understand there is an opportunity cost with any service and where those costs get realized, but your examples don’t seem like a slam dunk in apple’s favor.
The process you're describing is the exact thing you want to happen: junior developers are trying to learn to write better code. Why should they waste their time researching not their code base when they can instead learn off their code base from people experienced with it?

BRICS exists as an attempt by Putin and Co. to reduce dependency on global economy. Given Putin is waging what's basically a WW III, BRICS is simply his tool of war (not really effective and DOA in practice, but still). So as above, any kind of currency plans for it should be seen through that context.

Not easy, easier! For "external interruptions", you have to do both things, keep people from bugging you and control your own mind. I think it's definitely easier to only do one of the two, despite still being really hard.
I lived in california from elementary school through uni, consistently used "you all", and was consistently understood. "All you all", however, was hit or miss. I avoided using double modals unless I knew my audience.

(Having had yankee parents, I never had habitual or completed aspects in my idiolect. my best attempt: "I don't be using habitual aspect")

The AAVE modals ("fixing to" et.al.) have definitely become less segregated in online discourse this century; are they also more common in oral use?

(english lost its second person plural when "you" replaced the original second person singular. "You all" fits that spot perfectly, which would also explain why L2 english speakers also like to use it.)

Two things I think english currently lacks: (a) a good way to distinguish "we" (including addressee) from "we" (excluding them), and (b) a gender-neutral word that could be the equivalent of australian "mate".

You don't have one authority, you have multiple issuing authorities (the BRICS countries) with sometimes competing objectives. It's in the interests of these countries to have a "trust free" mechanism in the sense that it minimises the ability of the other countries to screw them over.
Things that can influence stall speed include weight, power, center of gravity, flaps/landing gear configuration, and more.

Why? Well, stall speed isn't a real thing. There isn't a speed at which you stall, that's not how it works. It's a convenient short-hand that we use for the more complicated reality. The physical reality is that stalls happen at a particular angle of attack (AOA) into the apparent wind. That is, the angle of your wings relative to the airflow. Up to the critical angle a higher AOA means more lift to counteract gravity. As you slow down you generate less lift because there's less airflow over the wings. So as you slow down, in order to generate a similar amount of lift you have to increase your AOA. If you keep slowing down and adjusting your AOA to compensate, you'll reach a speed that's low enough and therefore AOA high enough that adding more AOA no longer adds more lift (the air no longer flows smoothly over the wing). That's the stall speed, the speed at which more AOA no longer generates more lift. But it's the AOA that's the problem, not the airspeed.

In addition to lower speeds needing more AOA, you also need a higher AOA if you weigh more. A wrong but illustrative way to think about it might be that you need the engine's thrust pointed more towards the ground the more you weigh. That means that as you burn fuel (lose weight) the AOA that will stall you doesn't change, but the excess AOA available due to your weight-change does so in effect the air speed at which you would be near the critical AOA to stay airborn does change.

Stall speed is still a useful concept especially while landing but it's misleading outside of landing and when anything else is remotely unusual like weight or modifications to the plane. For this reason the FAA has been trying to get AOA indicators installed in planes and to train pilots to look at those instead of thinking about stall speeds https://www.faa.gov/sites/faa.gov/files/2022-01/Angle%20of%2...
Can you tell us more about it? Have you reported the results of your experiments in a post?
"As a result, the aircraft pitches up unless the pilot controls the flight path using the elevator. If this pitch up is not controlled, the aircraft is at risk of exceeding the stall angle of attack."

This has been happening for me in MSFS, and I considered it a really weird behavior - why can't I take off in a same way as from the runway? Now I know.
> Let's ask the question differently: what problems were solved?

A few more:

* Seamless internationalization. If you're a native English speaker you probably never experienced the "fun" of dealing with French and Russian in the same text document. Pre-Unicode supported English + one other language, if that other language wasn't too weird.

* Lots of tiny life quality improvements. Eg, not seeing windows repaint costs a LOT of memory. Every window is present in RAM even if not being looked at so that when you switch to it you never see it paint.

* Stability. Windows 9x tried to be frugal by keeping a copy of everything in system32. That was called "DLL hell". So the current standard is that the app just packages every framework, so you may have a half dozen copies of Qt easily.

> Do we need GBs instead of MBs for that? Why?

Well, let me look at my AppImage:

3.8 GB total.

2.3 GB of dependencies. 2.1 GB is libnode, 128 MB is Qt Webengine.

1.4 GB application. 126 MB of JavaScript and UI images. The rest is mostly code.
> The paper does not prove anything about the upper limit

Nothing can prove how many qubits can be realizable except trying to realize them. There will never be a theorem that says "The maximum number of qubits that can ever be controlled in a lab is X". That's what experiment is for.

I will say, it's difficult to doubt that the upper limit to the number of qubits we can realize is infinity. We can now trap ~10 million atoms and efficiently control hundreds of them: https://www.nature.com/articles/s41586-023-06927-3. The question is not "Could we ever realize billions of qubits?". It's "When can we realize billions qubits?". The answer could be decades or centuries but as long as people are building these devices, it will happen eventually.
Very little. It's heavily computer aided, but the overall design is largely done by humans with some marginal input by engineers for annoying realities like aerodynamics and sensors.

Bubblewrap is not that difficult.
IMO the biggest problem is simply that nothing is tested anymore on big inputs, and that frameworks and the modern way of writing code hide the complexity.

Also, in the past you had to care explicitly about how much memory you allocate etc. which stopped you to think. Now you can pretend you have infinite resources because everything happens implicitly.

No, the question was answered.

Every Apple user I know has had to contact Apple support due to an issue with their Apple device. Even the guy in this thread who claims never to have dealt with Apple support before had a comment in another Apple thread talking about their experience with Apple support. It was apparently great, but that's the problem. Apple service is great because almost every Apple user will have to interact with it because of a problem with their device.

HP, Surface, and Lenovo support can suck because so few people need to contact support for issues with their devices that it's not important to those companies to focus on support.

Apple announced the M3 on October 30 last year, roughly 6 months ago. Have they ever announced successive chip designs in such a short time frame?

What we really need is some way to force competition to be sportsmanlike. EG: cooperating to compete, just like well adjusted competitors in a friendly tournament who actually care about refining their own skills and facing a challenge from others who feel the same way instead of cutting corners and throats to get ahead.

Cooperation with no competition subtracts all urgency because one must prioritize not rocking the boat and one never knows what negative consequences any decision one makes might prove to have. You need both forces to be present, but cooperation must also be the background/default touchstone with adversarial competition employed as a tool within that framework.
This is plain wrong due to mixing of concepts. Language is technically something from Chomsky hierarchy. Predicting language is being able to tell if input is valid or invalid. LLMs do that, but they also build a statistical model across all valid inputs, and that is not just the language.

"When you are in a place with perhaps the most mundane music, if it gets even the least bit decent and you get up there and dance ecstatically, the band will love it.
If there are no dancers and you get up there at all the band will probably love it.

They might just not play so mundane after that.

And others who may be the least bit inspired will often get right up there with you, hesitating much less than they would have normally done."

Definitely, but it takes a lot of courage to do that. I am a very good dancer and I often was the only one dancing - and yes, the band of course loves it and usually also most other people.

But it is always a struggle to really let go and ignore all the thoughts of what others might think and just take the empty space in front of the band and go wild.

Ecstatic dance in the way I experienced it, is specially made to not have that crowd of judging outsiders and rather tries to create a safe space where everyone can just move how he or she feels like without being judged. (also phones are banned there, so no fear that someone might take a video of you, which is something that defninitely happens when dancing in public spaces).
