Theres a couple of mistakes here. Firstly the particle is not on its own, it is being acted on by the dome and by gravity.

The thing about symmetry breaking also doesn't make much sense. I guess you're trying to appeal to Noether's theorem, but Noether's theorem in classical mechanics is a consequence of f = ma. You derive the Lagrangian formulation of mechanics from f=ma and Noether's theorem from that. However the weird solution when then ball suddenly randomly falls down the dome after staying put for an arbitrary time is completely consistent with f=ma, so that can't help you here.

In any case the radial symmetry you're looking for (the system is invariant under rotations around the peak of the dome) implies conservation of angular momentum about this point, and not about any other point (since the setup is manifestly not symmetric under rotations about any other point). However (one can easily check) that for both the static solution and the randomly starts moving solution, the angler momentum about the axis through the peak of the dome is always zero.

You are worried about people in 200,000 years, where our entire society may collapse in a couple decades. Also you completely ignore that we are screwing the climate in such a way that it may take thousands of years to recover.

It's weird that not once do they mention or compare their results to the already-available quantization methods. I normally try to give benefit of the doubt, but there's really no way they're not aware that there are already widely used techniques for accomplishing this same thing, so the comparison benchmarks really should be there.

To fill in the gap, here's llama.cpp's comparison chart[0] for the different quantizations available for Llama 1. We can't compare directly with their Llama 2 metrics, but just comparing the percent change in speed and perplexity, MK-1 looks very similar to Q5_1. There's a small but not insignificant hit to perplexity, and a just over 2x speedup.

If these numbers are accurate, you can download pre-quantized Llama 2 models from Hugging Face that will perform essentially the same as what MK-1 is offering, with the Q5 files here: https://huggingface.co/TheBloke/Llama-2-13B-GGML/tree/main

> Most people aren't drinking butter-roasted coffee.

I'm not sure how 'most people' is relevant to the discussion. Fact is that it is one of the largest GDP exports for Vietnam and 5th in the world [0]. Just because you don't drink it, doesn't mean millions of other people aren't drinking it.

"The main destination of Coffee exports from Vietnam are: Germany ($384M), United States ($257M), Italy ($230M), Japan ($186M), and Spain ($150M)."

If I take those beans "shiny with oil" (aka: butter), grind them up and make a cup of coffee with them (I personally go with an aeropress w/ steel mesh), then there is going to be oil (butter) in that coffee. In fact, I can see a slight oil (butter) sheen on the surface of the cup of coffee if I let it sit.

In an ideal world, we really should have had another button or key combo for "I want to select the text" that isn't overloaded on "I want to select in general."

The old way was fine when word processors and other apps were completely separate beasts, but the web has blurred all of that and we are unfortunately albatross'd to decisions made in the past.

I want a fifth mouse button where 5-drag always means "select text" independent of all other UI content and as a result all text is selectable because text selection and other manipulations are totally different operations (at the event layer; "mouse down" and "mouse textselect" would be two different events).

Wishful thinking; we're stuck with the UI we have.

I just figured that’s the trade-off for general purpose computing.

Mind you I’m no expert, I’m just extrapolating on how differently what CPUs and GPUs are optimized for these days and historically.

Right. So not an expect in nuclear waste.

But which are built with fossil fuels, and which are cheaper in a world with abundant fossil fuels to make and transport them.

It's not clear at all that renewable energy can replace fossil fuels. Actually, it seems pretty clear that they can't. Even nuclear energy can't. It's just that we need to maintain some low-emission energy (as much as we can, which is not enough to avoid a degrowth).

This is nonsense. How do you extrapolate from some nuclear wastes to "human life is impossible"?

Fascinating. I'm really curious what the acoustic properties are that it's recognizing.

Is it more of a physical fingerprint of each key, such that if you swapped keys/springs the model would need to be updated? So it's produced by manufacturing inconsistencies, the way individual typewriters used to be forensically identified?

Or is more each key being identical, but producing a different resonance pattern within the keyboard/laptop due to the shape of all of the matter surrounding it? If you move the keyboard in the room, do you have to re-train the model?

I also wonder how much it varies depending on how hard you press each key -- not at all or a great deal? And what about by keyboard -- when you compare thin MacBook keys with an external full-height keyboard, is one easier/harder to recognize each key on than the other?

Eventually robotic missions will get there, but more often than not they will be as a vanguard for human exploration and settlement, because even though I put aside human motivation for arguments sake, in the real world humans have a deep desire to explore that cannot be placated with data from a probe.

What makes you think it's a made up number? Just because it's been featured in a movie doesn't mean the number can't be grounded in the reality of the era. Yes, there's exaggerations but big buget movies usually hire technical consultants to aid writers, prop builders and art directors with setting scenes that look realistic and don't just pull radom numbers out of thin air which could be embarrassing mistakes for tech-savvy movie goers.

60 TFLOPS is the equivalent of 10.000x PS2s of processing power, the most powerful console at the time, or 2x NEC Earth Simulator, the most powerful supercomputer at the time, which seems about right for what would be a virus taking over all the compute power of the DoD.

So definitely the writers consulted with some people who knew something about computers to get a figure grounded in reality at the time and not just pulled a random number out of thin air, especially that at the time even average joes were hearing about FLOPS as a measure of compute power, being advertised in PC and gaming console specs, so naturally they had to come up with a number that seemed very impresive but was also believable.

I happened on this ballad by pure chance. I always disliked that in Common Lisp nil is equal to the empty list, then I spent last week playing with Guile Scheme.

By the way, some (most?) videoconferencing software removes keyboard sounds from the audio, because it's particularly a distracting problem with laptops where the microphone is right next to the keys.

I'm pretty sure Zoom does this by default as part of its noise cancellation (it's potentially even easier since you can use keydown events to help identify, not just the audio stream).

So as long as basic default noise cancellation is on, that would at least prevent this over regular videoconferencing. And because of this, I'm having a hard time thinking of when else this would be a realistic threat, where the attacker wouldn't already have enough physical access to either install a regular keylogger or else a hidden camera.
For what it's worth, I only buy Android phones that have unlockable bootloaders and I can root so that ultimately I have control over my own device.

But yes, I agree on how letting Apple and Google assert a level of control unparalleled in the history of computing has been a massive step backwards for our industry and consumers in general.

> The assertion about the Copyright Office's batting average was yours. If you want to make the assertion, the research question's also yours!

I can't claim to have researched it formally, but my impression from reading a number of cases on the topic is that most of the time, the Courts end up agreeing with the Copyright Office. And more often than not, when they disagree with it, the disagreement gets reversed. For example, in National Broadcasting Co. v. Satellite Broadcast Networks, Inc (940 F.2d 1467 (11th Cir. 1991)), the 11th Circuit concluded that satellite broadcasters were cable systems. After oral argument, but before the decision was handed down, the Copyright Office issued a rule that they were not. The Court decided that the Office's rule was not retroactive, and hence did not apply to the case; they expressed doubts about whether they owed it deference, but avoided deciding that. Subsequently, in Satellite Broadcasting & Communications Ass'n of America v. Oman (17 F.3d 344 (11th Cir. 1994)), a different panel decided the Copyright Office rule was owed Chevron deference, and reversed a District Court decision applying that 1991 decision.

> As I recall, Skidmore held that what agencies say laws mean gets only the deference it deserves. In other words, the courts will reconsider for themselves how persuasive their arguments are.

You make Skidmore sound weaker than it actually is – in Skidmore, SCOTUS reversed the District Court and the 5th Circuit for failing to give sufficient deference to the statutory interpretations issued by the Department of Labor. Skidmore instructs Courts to evaluate an agency's "rulings, interpretations, and opinions", in light of "the thoroughness evident in its consideration, the validity of its reasoning, its consistency with earlier and later pronouncements, and all those factors which give it power to persuade". In other words, if a Court wants to reject an agency's interpretation, it has to present a persuasive argument that it is flawed on one of those grounds, or else the rejection has significant odds of being overturned on appeal.

> But last I checked, which was well after Chevron, questions about whether an application followed the registration process got deference, but the more basic question of whether something's copyrightable in the first place remained with the courts

In Varsity Brands, Inc. v. Star Athletica, LLC (799 F.3d 468 (6th Cir. 2015)), the Court of Appeals ruled that copyright registration decisions were owed Skidmore deference, and overturned the District Court for failing to extend that deference – in a dispute about copyrightability. It said that (in the 6th Circuit at least) when the Copyright Office judges a work to be copyrightable, as expressed through its decision to register the work, there is a rebuttable presumption that the Copyright Office's judgement is correct. That decision was upheld by the Supreme Court on appeal, but all three of majority, concurrence and dissent dodged the issue of deference entirely.

Eliminating the overlapping 5 does help your point, though I have a feeling Rust will be amongst the most dreaded once Rust is as old as VBA, Objective-C, or whatever “assembly” is… I don’t think it’s old code bases so much as it’s old languages that have accumulated a lot of cruft… the new hotness doesn’t (yet) have the cruft, but because human beings seem to inevitably want to force feature drift, it’ll inevitably gain cruft as it ages and tries to keep market share.

Without air conditioning, it wouldn't be surprising for the heat and humidity inside the trailer to surpass the human body's capacity to maintain body temperature.

Texas has been seeing unbearably hot weather, even for Texas, the past few months. High humidity is the norm.

The weather is literally lethal and cannot be survived by human bodies without breaks/cooling. Sweat alone isn't enough. Heat strokes are inevitable, especially when you're elderly.

(As an example, if my AC stops working during a Texas summer, the temperature in my relatively nice apartment will climb to the 90s F with high enough humidity that sweating barely keeps me cool.)
