After I broke my ankle (crushed between trees), they had to re-attach part of one of the bones (the ball part that goes into the socket) with 3 temporary pins. Once the pins were removed and I started walking again (after lots of physio), my ankle would swell up to the point where it would literally not move without cracking it first. Cracking would also instantly relieve 90% of the pressure and pain in the ankle for at least an hour or two, it was marvellous.

I've regained all of the extension motion and probably 70% of my retraction motion (moving toes towards knee), but only about 30% of the muscle strength. Unfortunately it still swells up after long periods of standing or hiking but I'm rarely able to crack it anymore, and really wish I could on those bad days.

So that's the exact same story for me! I started off with a road hybrid and discovered that I liked riding in the woods much more than I did on concrete. There is a lot of skill involved in mountain biking and it's fun to learn each technique: lifts, rolls, drops, jumps, rock gardens, climbing, and turning (I didn't even know there was a specific technique to turning on dirt but it's really important).

Expect to spend about three grand for a good full squish mountain bike. I have a Rocky Mountain and I would highly recommend the brand. They are one of the best values in terms of features, weight, and quality. There are even some really good direct-to-consumer brands now like YT. For mountain biking you definitely want disc brakes, a dropper post, and around 120mm-130mm of front travel with a total weight less then 28lbs. Global Mountain biking network on YouTube is a great resource as well as local riding clubs and bike shops. Good luck!
I know this response is a little tongue in cheek, but you make a good point regarding entertainment. It seems like passive entertainment is a sort of sponge of energy and attention in a society. At a certain size, that probably helps keep things organized, but if that option is not available, the group has to come up with elaborate ways to expend that excess energy.

Once all the survival tasks are done, you really don’t want a bunch of military-age males standing around listless without direction. I think this was part of the pressure that gave way to elaborate rituals, construction projects, exploration, etc.
That was quite the read! Thanks for sharing it. I do wonder what the future is for at-home concerts. The Travis Scott Fortnight event was really neat and kind of mesmerizing; the track was highly anticipated, which helped a lot. It was neat that you could interact with it a bit. The article mentions the production value that TV stations add to sports broadcasts: while the article talks about commentary a lot, what I appreciate about football broadcasts are the slow-motion replays, the sound captures, and the dramatic shots of notable players and coaches. From the concerts I've watched on TV, there's quite a bit of newer production strategies that could probably be used like modern audio production techniques and audio-synced CGI effects.
> Their business model is selling complete control over people at the population level. At some point it will stop being a business model and start being a self sustaining model of raw power that strips us of our humanity.

Calling it "complete control" is absurd hyperbole ans ignores that psychological manipulation isn't even remotely new. In fact the goddamned politicians implicitly called upon to ban this are psychological manipulators already. So were televangalists, every theocrat and strongman who suppressed dissent enough that his victims were stockholmed.

It cannot strip us of humanity - although it would be a good thing if it could because "humanity" in that context is a collection of bugs exploited for evil.

> it's never an ellipse because the Earth is not a point mass.

At least classically, a sphere is indistinguishable (gravitationally) from a point mass while you're outside it. The earth is pretty sphere-ish, locally speaking.
Spherical mass can be replaced with a point mass. Earth however is not spherical (biggest deviation is polar flattening). And even then, Einstein's model, unlike Newton's, says it's not an ellipse even for a point mass.

So, moral of the story - we have to be not too pedantic.
Isn't this code kind of supporting the first point in the article?
I mean, the article started by pointing how rust "protected" you from a "TTCTTOU" error.

This C code is not only not protecting you against that, but also it seems to have little to none error checking. What happens if fopen fails? It just skips to the next file and happily ignores all the entries in the file. What if fget fails? Again, it stops processing the file and goes to the next.

I won't even get into what happens if calloc fails and returns null. Or if ++ wraps around and you get a negative value (let's hope we are using 64 bits)

This program will likely work, but if it doesn't you will just get an invalid number and never find out.

Don't get me wrong, I understand this is "not serious" code, written in a Sunday and for fun. And I would be ok with it if the article wasn't about language safety.
Trek the Vote
In hindsight we know now what was problematic about the lisp reader conventions.
The default should have been lowercase case-sensitive, esp. for the ffi.

But we've only got uppercase case-insensitive, with flags for inverse (an ugly hack) and case-sensitive. This way you can call C or Java functions, but internally it's all case inversed. And still broken in some lisps
I've always intuitively understood this to be the reason why it would take infinite force to achieve light speed for a massive object. When we apply a physical force, it is applied in the spatial axes, so it is always perpendicular to the time axis. Acceleration is just rotating some magnitude of your fixed velocity vector out of the time axis and into the spatial axes. When your spatial velocity is apparently zero, then the component of force that is perpendicular to your velocity is large, so you achieve a large deflection. But as you rotate velocity out of time and into space, it becomes more perpendicular to time, so any force applied perpendicularly to time is now more parallel to your velocity, having a smaller component perpendicular to one's velocity. You can't rotate a vector with a parallel force.

This is also why you can't travel backwards in time through just acceleration. There is no way to impart a force perpendicular to your velocity vector when it is already perpendicular to time, giving you no way to rotate the vector to have a component that points backward in time.

So I've always wondered, whether general relativity allows for forces parallel to time, and we just don't know of any mechanism to actually do so, or if it does not cover such cases because we have no mechanism, or if it disallows it entirely.

Would not an electron and a positron trace out an identical line/parabola?

Would that mean electromagnetism is not a force either?

What is the difference between the two that makes one a force and one not a force?
> Were either of these characters even PoWs? I doubt it.

What’s your basis for doubting that McCain was a POW?
The difference is that light travels through space, but not time (similar to how a vertical line does not travel the x axis, only the y axis). The ball travels through both space and time.

The faster you go, the less you travel through time. Thus, if the ball were travelling at the speed of light, it would not travel through time either and would follow the same path as light.

I didn't read the story.
There's not a single western industrialized nation or state that can be pointed to now as a mask success story. There were a few countries in eastern europe (specifically czechia) that were heralded as a primary reason for controlling covid in the spring.

We now know that this apparent good result was not because of masks, but because of geography. Czechia is ranked #1 in the world in cases / million in the last week and #3 in deaths / million (and its numbers are still climbing). Every single eastern european nation had low cases/deaths in the spring and now all of them are having their first large surge.

It's abundantly clear that cloth masks, as a whole, do not play a major role in how the virus spreads in a country.

Yep, though specifically because it’s harming Google’s competition rather than users.
The falling object doesn't accelerate. You, standing on the ground are the one that's accelerating. You see the object as accelerating but that's an illusion due to frames of reference.

As evidence: which object feels a force on it?

You can feel the force the ground continually pushes up at you. The ground is accelerating you up. The falling object is completely idle in its inertial frame and feels nothing.
I think you mean centripetal force.

So, first and foremost - apologies. I had read two replies and put them together in my head when replying to you. So, yes, I agree with what you are saying here.

The idea that I was trying to get at is that you can accept that you were a victim and do something about it. We are saying the same thing - but you are saying it better, so sorry for the confusion.

Additionally, some people are victims of situations - so say, poor family background, a minority race that is looked down upon by the majority, having a chronic illness - and you can accept that is true but mentally decide that you are going to take steps to make it better, however you can.

You don't want to land in "I have no control and am a victim" when you are being victimized. That is what you are getting at too.

As a society, we don't want to create a society where anyone being abused feels like continuing to be abused is actually better than looking for help / making a change. That's not the victim's fault... that's someone choosing what they see as the best of two not attractive outcomes.

> Could >100 FPS be realistically achieved today using only CPUs or mobile phones?

Not yet.

Google's MediaPipe object detector (which is one of the most optimised mobile solutions around) can do "26fps on an Adreno 650 mobile GPU"[1].

The Adreno 650 is the GPU in the Snapdragon 865, ie the current high end SOC used by most non-Apple phones. This gives roughly the same performance as an iPhone 11.

Traditional media companies have a motive for social media to implement prohibitive self policing measures. Youtube recently caved and gave media companies an extra boost in their trending algorithm and exceptions to expletive language, which made vloggers upset: https://www.bbc.com/news/technology-44279189

Traditional media tends to stick to big three excuses to implement these measures; 'think of the children', terrorism, and cyber bulling.

It makes it more special.

oh I get it I just don't care about those into not caring. i for one see too many interesting promising things as near at hand to let such willful unconcern reduce my gusto.

your assumption that the translation layer is all that counts assumes driver parity between os'es. both for 3d & game streaming, there are significant performance and capability differences between os'es.

but mostly, long run, i think it's important that the gaming ecosystem remain technically healthy. i see a lot of interest again in cross-platform tech like Vulkan. linux is thankfully in a great position to just run, very well, with modern engines. the long work building & optimizing compatibility systems has, thamlnkfully, given Linux a lot of experience to get fast & otherwise (audio, input, netcode, &c) capable, which all pays off again now that games run natively too.

your honest account is welcome. you are free to not care, to assume this would only ever be an ill fit for you. i'm not sure why you'd spend so much effort so loudly making your personal point about your expectations on a day when others are happy & revelling in the ongoing progress & hope & freedom & opening of possibilities that they want to see. it's, again, ok that you are opting out. but a lot of us are excited that cutting edge gaming can & is happening in more diverse places than it used to, & we foresee only better.

The model shown is for 1D space and 1D time, and this 2D spacetime is curved, remaining 2D. Can you though show us a 3D model of curved 2D spacetime? Maybe as a rotatable, scaleable 3D scene, where more complex phenomena, like planetary motion around a star, would be possible to show?
I've come to the conclusion that the discrete interface of the keyboard and keypresses meshes well with the discrete nature of text versus the analog control the mouse gives. When selecting by individual characters/lines, I'd much rather use my keyboard and know that for each keypress I'm interacting with some X amount of text than fumble with my mouse until I get exactly what I want selected. Vim keybindings specifically are nice because they provide a pretty universal interface - most applications I use implement Vim keybindings, so there's very little context switching when working with my IDE, CLI file browser, Firefox w/ Vim Vixen, etc.

Also, I find that preventing constant movement from the keyboard to my mouse and back helps mitigate wrist pain and discomfort from long sessions at my PC.

> If you're asking questions then confidence that the answer - which you do not know - is simple betrays the reality that you've become falsely confident of your understanding despite the fact that you don't know what you're doing or else you wouldn't have a question at all.

That's a lot of assumptions without even knowing the question, and is symptomatic of troublesome responders.

A lot of times the question I ask is of the form "Yes/No".

As in "Is it possible to do it using X?" If the answer is "Yes" I may have follow ons, but it's amazing how often I cannot get an answer to this question. Even a "Yes, but it's a bad idea" will suffice, but I'm more likely to get several "You probably want to use Y". That's simply not answering my question at all.

"Can doing it via X handle a size of N?"

Sure, maybe doing it Y is usually better than doing it with X, but telling me that is not answering my question, and the majority of times Y will not solve my problem. I also may already know that Y scales better, but my point is that even stating that up front in the question will not get me the answer I am seeking.

Sometimes I'm just curious. I know Y is better, but I want to know what the limits of X are. It's an appropriate question.

Depending on how well I know the person, I may give context, which is part of the skill in asking good questions. However, in an impersonal online setting, this backfires more often than not. As the example showed above, it usually leads to a 5x more effort spent in explaining and justifying the context than in discussions that are on the route to my getting an answer.

(As an aside, I do come from an academic background, where it is the norm to explore, and be curious. A lot of the questions they ask and discussions they have are not for anything practical. Which then becomes annoying when they ask a question online and the other party has all kinds of assumptions on why I may want to do X.)

> Asking questions is a skill

Agreed, and so is answering questions. Jumping to conclusions on what the questioner is trying to do means the person has poor answering skills.
