Possible alternative, but what would be a factor of locality in such an universe? And how would the universe store the infinite "light matter" in it's "memory", since light particle beam being instant means that it has no limits to where it can reach, and will grow depending on distance traveled (which is infinite)?

Some processes that are outside of scope we can sense seems like a too cheap explanation.
I consider C++ a copy-by-default language (and pointer/ref being the necessary evil which breaks this great default).

In Rust, it's move by default and you need an explicit .clone()

I think you can still take advantage of paravirtualization without running an OS built for Apple Silicon specifically. You can emulate peripherals and the motherboard and stuff without emulating the CPU, so you would probably do better just to run the regular ARM variant of whatever distro.

Both Arch and Fedora, which some releases of Asahi are based on, have regular, shmegular ARM variants.

There's risk in all manner of things. Some I would personally consider as high risk for relatively low personal reward--or I'm not physically capable of doing them anyway (which alas covers more things than used to be the case).

But people like challenges, experiences, etc. some of which are never going to be wholly risk free. I'm not going to pressure someone to get out of their comfort zone in a way that puts them in potential physical danger but I fully understand people who pressure themselves. I've certainly gotten into some dicey situations now and then. Nothing serious happened--I was generally prepared--but it wouldn't have taken a lot for things to go sideways.

Or maybe you get distracted and forget to look both ways before crossing the street.

if he had studied molecular biology he might have had a different opinion - though probably not.
Right, but the original characterization was clearly about the discussion on the github issue that was closed.
In college, I was always the first one out of my friends to “get” a concept, like fast Fourier transforms, anything with signal processing or even coding or any labs we had to do etc so I would spend time teaching them in the library. However I never did any of the exercises, mostly due to laziness and not arrogance. They would get A’s and I would get C’s and D’s.

I emphasize this story to my kids because knowing isn’t important because everyone eventually figure it out. It’s the ones who can do the problems and get good marks that succeed in the end.
I mostly use awk over perl because awk is completely documented in one man page, so it's easy to see whether awk will be fit for purpose or whether I should write it using a real programming language. I learned Perl over a decade ago, but not the really concise dialect you would use on the command line for stuff I'd use awk for, and I've forgotten almost all of it now. At least with awk it's easy to relearn the functions I need when I need it.
If someone doesn't know awk, then of course it'll be complicated and opaque - the same is true of practically any language. One-liners in general also tend to optimize for space. If you wanted it to be pretty-printed and with variable names that are more obvious:

{
PROCINFO["sorted_in"] = "@val_num_desc"
top_ips[$1]++
}
END {
counter = 0
for (i in top_ips) {
if (counter++ < 10) {
print top_ips[i], i
}
}
}

But also, if you read further up in the thread, you'll see that another user correctly identified the bottlenecks in the original pipeline, and applying those optimizations made it about 3x as fast as the awk one. Arguably, if you weren't familiar with the tools (and their specific implementations, like how GNU sort and BSD sort have wildly different default buffer sizes), you'd still be facing the same problem.

At least half of what people complain about with shell scripts can be solved by using ShellCheck [0], and understanding what it's asking you to do. I disagree with the common opinion of "anything beyond a few lines should be a Python script instead." If you're careful with variable scoping and error handling, bash is perfectly functional for many uses.

Unfortunately, the support for transferring eSIM between devices is not universal and some operators choose not to support it and charge money for each transfer(i.e. charge money to generate a QR code). The tech is fine but the greedy telcos don't miss the opportunity to screw us over.

A transition from plasma to the cold mater in the form of galaxies we see.

As you see, there are big clusters everywhere. It means that some regions were cooler from the start, to form these cluster in so short period of time. It means that regions around them were hotter, thus they should emit light longer.

> If there is we'd have to wait for the light from it to get to us, by which time the CMB will have receded further and it would then be in front of the CMB.

In case of a complete redesign, yes you're right. With a generic API you will have about as much trouble writing the redesign as you did the original design.

In practice, a complete redesign is an incredibly rare event, and a good problem to have. Usually design of individual pages and layouts undergoes gradual, incremental changes, driven by real needs.

A redesign that requires front-end restructuring to such an extent that the data supplied is no longer sufficient should probably involve backend collaboration. Otherwise, you're tasking your backend team with building a generic site builder, which is much harder than a specific backend for your frontend.
After some research I've found this thread on XDA: https://forum.xda-developers.com/t/a-tricky-way-to-use-esim-...

Seems like it should be possible to solder an eUICC chip to a SIM-card form factor board and use it with OpenEUICC. [1] Somebody is even selling those pre-soldered on Taobao: https://shop104192953.world.taobao.com/

Later in that thread, somebody also reported that OpenEUICC works with eSIM.me's cards, too. If you have one of these, can you give it a try perhaps?

AI vs. Blood Mouse – Disney, AI Art, and Copyright [video]
The 15-minute video covers the consequences of so-called "ethical AI", which is giant corporations such as Disney, with IP hoards big enough to train AI models, get to use the technology unhindered, while for individuals it becomes prohibitively expensive or outright illegal. This is supported by the Copyright Alliance (members including Disney, Paramount, and the RIAA) lobbying for expanding copyright to cover AI models and their output. They're also running astroturf campaigns to trick independent artists into supporting their position, while on the other side lobbying politicians for these copyright expansions, and working to create enforcement systems, such as upload filters and content provenance verification schemes [1].

Not sure I follow, methylation analysis is very different from NA detection.
As a physicist, fluid mechanics was the most glaring gap in my undergraduate preparation, despite its centrality to most physics applications. Somehow it is always a “time permitting” topic at the end of an already-cramped curriculum.

I first encountered the Euler equation in the context of GR — absurd. In another decade or two, I suspect its rightful place early in the physics curriculum will be emphasized.

No, it’s a game of hot potato, subsidy gaming, and tax arbitrage played by out-of-state landlords. Many of these homes are vacant, unwanted. For reasons I do not understand, many people will prefer to rent than own, even if renting costs more out-of-pocket. Not a function of affordability, but an apparent lack of understanding across the community. What you are describing is not what’s happening in Memphis. The homes are available, almost freely available, maybe require some sweat equity, but nobody wants to bother. Again, I’m talking about thousands or tens of thousands of homes. The jobs are there too, we have a lot of trouble hiring in town.

I don’t mean to invalidate the decisionmaking process of low income people in this context, but it doesn’t make sense to me, it’s not for lack of available housing, and it’s a problem I’ve personally spent a lot of time trying to solve over the last 15 years.
I love HN for thing like these that I wouldn't have otherwise found out. I used to think often about physics but not seriously enough to search for resources on how to get started and learn. But now that I have this guide (thank you Susan), I think I will start and no longer wonder or plan for learning physics in the future.
This is a terrible strawman. I haven't seen anyone here make a claim that homeless have no moral worth or being unworthy of respect. I think there's a case made for the opposite: expecting someone to be actively working towards self-sufficiency (if they're capable) is treating them with a modicum of decency and respect by not infantilizing them.
"According to the newly received wisdom, anyone who hadn’t suspected a lab leak all along was either a CCP stooge or painfully obtuse..."

Huh? I am open to the lab-leak hypothesis, have friends who believe even the bioweapon version, and even I don't know anyone who thinks this. Perhaps someone does somewhere, but "newly received wisdom" implies that it is the standard belief.

I think the more widely shared belief is that it is difficult to trust any industry to investigate itself, and so it is difficult to trust the virus-research community to come to the conclusion "we have investigated ourselves, and found ourselves not at fault".

That's a big if, which quickly shot down my then early and naive absolute determinism view when Heisenberg uncertainty principle reared its head:

A short way to describe this: you have to throw away all high-level type information in order to execute code on real machines, so the choice becomes when to throw it away.

CLR languages throw it away in the runtime, JVM languages throw some away in bytecode, and Haskell throws it all away in the compiler.

> Don’t you think it makes sense to attack the root problem (addiction) as well as the “big symptoms”?

Addiction very often isn’t the root problem, there may not even be a unique root problem. Addiction is a difficult to manage persistent condition that complicates, is conplicated by, reinforces, and co-occurs with other problems, which may be caused by it, may cause it, or may be linked by more distant causal connections or not, at root, commonly caused despite interacting and reinforcing each other once present.

You need to deal with the complex situation presented, not try to solve a tricky and generally unsolvable chicken-and-egg problem that is usually irrelevant to the path forward.
just start with the Feynman undergraduate lectures (listed). The easy-mode of that is "Six Easy Pieces" (read it on kindle) which are the easiest 6 lectures.

At some point you'll need math, I recommend https://www.amazon.com/No-bullshit-guide-linear-algebra/dp/0... (I actually started here), and for calculus, "No BS Guide to Math/Physics" by the same author. These books both include a review of high school math (i.e. trig) which i needed. For DiffEq I currently recommend Logan's "A First Course in Differential Equations", this is where I am now and I found this the most gentle after trying several textbooks recommended from r/math. Context: I am an adult with an engineering degree from 20 yrs ago.

I first came across her words in the book Cloud Native Infrastructure, and she had a way to say things concisely, things I had always wanted to express, but never had the words. I was an instant fan. I ran into once at Salesforce Park in SF, and told her about how I followed her and loved her works. It so happened she was talking to a VP at the time, explaining the importance of social media in tech, to that worked perfectly for her. I'll never forget her, and cherish her forever.
So happy to see the love for Griffith’s Intro to Electrodynamics. I know it gets dinged for not being sufficiently rigorous, but I’ve never read another math or science textbook that did as good a job of getting a beginner to truly understand the subject.
This is such old news by now. They had to publish something but they weren’t exactly breaking the news either.

I did read through the few most recent murder miscarriages and still believe this is very much different. For one its a serial killing case with years of evidence piled up not an isolated murder. The bodies are clearly there unlike one of the miscarriages, there is a confession note and medical evidence of poisoning. The whole thing happened over years in a hospital with many people around and very detailed records, very unlike any of the miscarriage cases. One miscarriage had no body or timeline, one had no proof besides a few eyewitnesses, one seemed to based largely on past bad conduct with little concrete evidence of the crime he was on trial for.

My point is just because the system fails occasionally shouldn't bias us to believe every conviction is wrong. But yeah you are of course free to doubt any conviction you like.
This is the opposite, though. In order to cobble together a number that seems even remotely problematic they had to combine several things that are weakly related: all IT workloads, plus all wireless networks. They also needed to express it in terms of global electricity, instead of global primary energy, because it is absolutely dwarfed by fuel burned for transport. Finally, this is a consumer that can be trivially decarbonized.

Compare private passenger cars which are ~12% of global CO2 and there are no practical ways to decarbonize that.
It's not their home if they're not paying for it though, assuming you believe in property rights.

So, there were labs in the Wuhan area, co-sponsored by China and the US nonetheless, and doing research on exactly that family of viruses, but it's "more possible" that the virus came from nature in the exact same area's wet markets, the same kind of markets that operated in China (and all over the world) for millenia, of which there are still thousands upon thousands in the developing world.

Sure.
My completely uninformed guess is that this project was in the works for years, and it's not simple to postpone. For example, they would have mapped out where the moon was going to be, what its rotation would look like, how they were going to approach, etc.

Perhaps this is easy to re-calculate for another year, but when you're dealing with narrow tolerances for error, maybe there's a heavy bias to just stick to the plan? They probably were also hoping for a PR win, which obviously backfired in this case.
The source likely says “x g of co2 per kWh”, and doesn’t break that into fixed and variable.

I suspect the sources would typically underestimate legacy sources (meausiring the co2 from burning gas but not the co2 from maintaining the oil rig)
Sure, one simple sentence is not going to explain the universe. But, at least from the simple relativity side of things, essentially everything falls out of (that is, it's a consequence of) that simple sentence. I.e. starting from that you can derive other consequences. E.g. "how the energy required for an object with mass to approximate the speed of light in spacial dimensions goes to infinity" is actually a direct consequence of that statement: every amount of energy you push into an object with mass causes it to accelerate, but due to the essential "clock speed of the universe", that acceleration is less and less as you approach the speed of light, and thus it takes an infinite amount of energy to reach the speed of light. Another way to think of it is that if it took anything less than an infinite amount of energy to reach the speed of light, then the speed of light couldn't be the universal speed limit, because you could add more energy that would accelerate it further.

On the other hand, my understanding is that quantum mechanics is another beast entirely, and one of the biggest problems in physics, and to developing a "theory of everything", is to unify quantum mechanics with general relativity.
> they are and have been dreadfully underserved and underestimated by the academic physics community (who do not take them seriously because they aren’t studying at colleges and universities)

This stuck out, pretty rigorous if all you want to satisfy your curiosity. If you want to actually apply any of the hard work you put in, you need a degree.

I think that is the most interesting part of learning anything, applying it interesting ways. Doing that within so many of the areas of study is still gated behind academics.

That killed my motivation for putting effort into most things, pretty much except computer science where we are still ok with trusting self taught people for some reason. But to do anything interesting physics, astronomy, philosophy too you need to be in school. sucks
"Please respect the truism that if you have a great career and a crappy marriage you will be unhappy, but if you have a great marriage and a crappy career you will be happy."

This may be true, but it complete ignores the alternative of being single. And if you have a crappy career and a great marriage now, that crappy career and the financial problems it may bring might eventually affect the marriage too.

Disclaimer: I'm single. A few bad relationships were enough for me!
I think this is taking an expansive view of labor e.g. writing all datacenter applications as optimal code in low level languages.

The general disinterest in performance/efficiency work even for large scale datacenters is a major theme of Dan Luu’s writing. I’m not sure how that applies to the rest of the industry but I can attest that my company’s performance engineering team has been zeroed in every round of layoffs we’ve ever had.
I just do my darndest never ever use the heap. Let the stack be your memory manager.

Invoke what exactly? Im sorry I don't understand what you're trying to say here.

I guess you can force all derivied types to implement a clone() function, such that box<T> can do the deep copy, but Id consider that a fairly big inconvenience for such a simple pointer type.
