The neutrons and the antineutrons are made of multiple electrically charged particles whose electric charges sum to zero, exactly like the electric charges of all particles that compose a neutral atom or neutral anti-atom sum to zero.

Therefore there is no path to generate antineutrons in which you do not have pairs of electrically charged particles with opposite charges that are generated or annihilated.

The annihilation and pair generation reactions are electromagnetic interactions between electrically charged particles and antiparticles with opposite electric charges, which are otherwise identical, in order to satisfy all conservation laws.

Only the neutrinos do not have electric charge and about them it has not been proved beyond reasonable doubt that the antineutrinos are different from the neutrinos (in other ways except opposite spin). Neutrinos do not participate in annihilation and pair generation reactions.

Neutrinos may appear and disappear in similar reactions that are mediated by weak interactions (i.e. by the heavy bosons), like the inter-conversions between protons and neutrons (actually between u and d quarks), but in these weak-force based reactions the energy that is produced is much less than in annihilation reactions and frequently much of it is lost by being carried away by neutrinos. It is possible to make electric generators with beta-radioactive isotopes, where this kind of reactions happen, but the only advantage of those is the extremely long lifetime, because otherwise the power density and energy density are low.

So when talking about using antimatter for energy storage purposes, that refers exclusively to generating electrically-charged particle-antiparticle pairs, separating and storing the antiparticles, then annihilating the antiparticles with their corresponding particles, resulting in extremely intense gamma radiation, which carries the reaction energy.

When the annihilation is done inside matter, which includes annihilation between nucleons (where there may be multiple annihilation events between the component quarks) the gamma photons interact with the surrounding matter or sub-nucleon components, producing a cascade of various accelerated particles, including many new particle-antiparticle pairs, which will cause later other annihilations. So from a single initial annihilation a great number of accelerated particles and gamma photons may result, but the first stage is always the generation of a pair of gamma photons.

You misunderstood, the main issue is that there's some user/pass auth code of unknown quality exposed, instead of basic auth done by some battle tested httpd implementation like apache/nginx. Which in ideal case, is also split from the application and can be independently updated if needed. That certainly does affect security posture.
Huh, my experience was quite different. I fed it this picture:

There are more operating systems written in C++ than Go or Rust which you mention elsewhere. Microsoft Windows is the most popular operating system in the world and it's written in C++ primarily. C++ can be easily integrated anywhere C is used, provided hardware is good enough. System programmers are more likely to know C and C++ than Java, Go, or Rust. If a toaster has enough CPU to run Doom then I think your arguments against C++ "bloat" don't hold any water, and probably haven't made sense since the 90s.

As far as mentioning shell and Python, I don't consider those primary system programmer tools. You might need to know them to be a good generalist *nix system programmer, but it's really tangential to whether C++ has a place in systems programming. Python and shell are in competition with Perl and Tcl, not with C++. To say that they are is like saying a carpenter is in competition with a welder because they both build stuff.

Good software shops leave a good amount of "slack" time for their engineers. It's how you handle shit hitting the fan without burnout.

I currently work on a team that has been basically solving multiple crises per year for years now. In the blips where we've returned to normalcy, we didn't push hard. Because we knew that was time to recover because another crisis was definitely coming.

The crises were external / due to leadership being aggressive without our input..so at that point, all you can do is execute. And part of executing is resting.

> Not everyone has a telework job. And many who do still have to be available during "business hours”.

Yes, and DST doesn’t help with that either. My point was simply that those are things which actually change the time available for many millions of people whereas in the winter the time change just controls whether it’s darker in the morning or evening without changing the number of hours.

Right now, I have a little over 9 hours of daylight. DST offsets can change whether that starts earlier or later but it doesn’t add more time so if we shift the start so fewer people are going to work in the dark, more people will be going home in the dark. If we don’t do things like add before/aftercare for kids, too, then many people won’t even have the option of adjusting their schedules to optimize the available daytime.

I have a big problem with comparing a pocket supercomputer to booze. It's nothing like that. And I don't just think that because I can manage, everyone else can. I also think that this regulation will be counter productive.

You raised an interesting point while talking about the professionals at school vs some backwater person. I wish I had your trust in their good intentions and abilities, but where I live these supposed professionals don't even speak English, and they're pushing their conservative agendas. It isn't unusual that my kid googles some bullshit a teacher says and it's proven wrong by a fact checking organization. For example, if my kids couldn't fact check all the shit they said during covid, I would be very unhappy.
Seth Klarman, in Margin of Safety, is refreshingly clear on this. The aim is always to buy something worth a dollar, for less than a dollar. You, not the market, must determine what the asset is worth. That generally requires a significant amount of investigation.

If you are not up for that, Klarman explicitly notes that index investing will be fine, but not spectacular, and in particular the index will trade in stocks for no good (investment) reason but simply because they have to keep the index balanced.

Trading on news and events is essentially gambling, although you can use other people's reaction to news to time investments so long as you've already decided to invest and were simply waiting for the price to meet your criteria to make the trade.
Aging and cognitive decline is real. I do notice I don’t respond as quickly as in my twenties when presented with problems that require logical reasoning and abstract pattern recognition for example. This is usually not a problem because most of the tasks I execute on a daily basis don’t require these skills. But it is evident that the decline is there and I think it’s important to recognize it. On the positive side at this stage of my professional and social life I believe experience is much more important to succeed than sharpness of mind. However experience is memory and memory also declines with age.

I think you could make it work for negative numbers. You would just shade the negative area differently to show it. For example, if you subtract 1000 sq ft from 100 sq ft, geometrically it means you are trying to remove more area than you have. So, to represent this, draw a rectangle of 100 sq ft. Conceptually "extend" this area by subtracting 1000 sq ft. The extra 900 sq ft that you try to subtract but can't "exists" as a negative representation. This could be represented by flipping the surplus 900 sq ft into a negative axis or shading it differently to denote that it's a deficit rather than an actual, positive area.

> One might suggest using a VPN to secure the connection. However, this approach is impractical for several reasons:

> Complexity: Routing general internet traffic through a VPN introduces unnecessary complexity.

I don't believe that it's that bad if your pefered option is a reverse proxy. Frankly, wireguard isn't that complex on its own merits.

> Bandwidth Limitations: A VPN could bottleneck the performance for some devices.

Nonsense; this is a VPN for a specific purpose that uses virtually no bandwidth. Obviously don't run all traffic over it, but with that done it should be fine.

> Device Compatibility: Not all devices can reliably connect to a VPN.

True... but I thought this was just for cell phones? Because wireguard at least works on (at least) iOS, Android, and postmarketos. (And I'm pretty sure most other popular VPNs do as well.)

> No Basic Authentication Support: Home Assistant's mobile apps cannot handle URLs with embedded credentials (e.g., https://user:pass@hostname).

That is a shortcoming, but not necessarily fatal; can it sit behind a reverse proxy that handles (http basic) authentication but doesn't use another path? That should be secure enough.
Yeah, I have the same experiences with Wayland. In fact, whenever I see it being mentioned and that it may be the default, I tend to just try to avoid the program in which it is default because I've always had issues with it. X11 works. These days are long gone where you have to modify X11 config as well, just run "nvidia-xconfig" or whatever. I do not remember the last time I had to mess around with X11. Wayland less so, as many essential features were not working. X11 has more than one clipboards as well, and I have no clue if Wayland has them, too, and we are talking about something very basic.
It is certainly a stronger argument in the gun case, since defensive usage significantly outweighs criminal usage and most people don't even shoot anyone. Here we're dealing with a situation where being addicted to your smartphone is the norm, not the exception.
A bit of a catch-22, right? In any case, there is going to be an "in the meantime" until reviews get published, and probably even more time before some more well-known channels possibly decide to get their hands on it and talk about it.

Any effort to get early wave buy-in from a certain (IMO critical and not uncommon) type of enthusiast (i.e., someone like me) in that meantime will be cripplingly handicapped by their web presence lacking information and not showing anything w.r.t. what the real-life use looks like.

Here are over a dozen TeaVM-based projects, for inspiration: https://www.frequal.com/TeaVM/TeaVmBasedSites.html

Several use cases where TeaVM shines:

* A developer or team has strong Java skills and wants to develop single-page apps

* A Java desktop project wants to move to the web and has lots of validation logic they don't want to double-maintain in Java and ECMAScript/WASM

* A Java-based game developer wants to make a Canvas-based version of their game for the web (potentially full-screen)

* A Java developer wants a batteries-included framework for web development. TeaVM comes with a minifier, tree-shaker, packager, and more, out of the box, with familiar 'mvn clean install' semantics (And Gradle support too).

For more details on use cases and reasons for picking TeaVM, read chapter 1 of my book here: https://frequal.com/Flavour/book.html

Money. Budget.

This comes from New York government. They want to get the job "done" with as little money as possible.

I vaguely remember a quote from a governor who says "The government should not be in the business of developing mobile apps." (I can't find the exact quote right now.) I don't know what happened after that, but you can imagine these things could happen if you replace in-house developers with outsourced work.
I agree with this take actually. I do imagine how programming in the future could be comprised of mostly interactions with LLMs. Such interactions would probably constrained enough to get the success rate of LLMs sufficiently high, maybe involving specialized DSLs made for LLMs.

I do think the future may be more varied. Just like today where I look at kernel/systems/DB engineering and it seems almost arcane to me, I feel like there will be another stratum created, working on things where LLMs don't suffice.

A lot of this will also depend on how far LLMs get. I would think that there would have to be more ChatGPT-like breakthroughs before this new type of developer can come.

I believe ARM just revoked Qualcomm’s architecture license, so they no longer have that option if they want to run aarch64.

The architecture license predated the Nuvia acquisition, and was the license under which Qualcomm developed their most recent laptop core.

At some point I think humanity is going to have to really declare war on addiction. I’ve been thinking about this for years.

It’s not unprecedented. China threw off the yoke of opium for one example.

I’m all for free speech and I am against drug criminalization— as long as in both cases the stuff is not particularly addictive.

The deliberate use of addiction to ensnare, monetize, or control other people whether through substances, tech, or other media should be a crime. It could be considered a form of assault.

It would be a crime to implant a chip in someone while they slept that could be used to remotely regulate their emotions somehow, right? How is deliberate deployment of addiction different? Instead of implanting something you are exploiting what amounts to a CVE in the human brain. It’s a crime to break into your computer using a zero day, but it’s okay for me to hack your brain?

This is the “Butlerian Jihad” we need — not against technology but against addiction. “Thou shalt not exploit security vulnerabilities in the human mind.”

We know enough about the mechanisms of addiction that I think we can be reasonably objective about identifying it.

A first step might be to make it civilly actionable. If you can prove that someone deliberately worked to make their product addictive they can be the target of a class action lawsuit. You could, for example, sue social media companies for the hours of lost time resulting from their addictive designs.
I did a similar proctored digital coin toss type experiment at uni back in the dark ages.

In the proctored experiment the best rate of pay was achieved by those who just skipped trading for each of the 15 days and left after 2 minutes with $50 in their back pocket.

I would like to see the payout distribution graph with random trades for comparison against the students.
The post I was replying to claims that probability is not a physical property of an observed system, that it is a property of an observer trying to observe a system. The examples given in the quoted link all talk about experiments like rolling dice or tossing coins, and explain that knowledge of mechanics shows that these things are perfectly predictable mechanical processes, and so any "probability" we assign to them is only a measure of our own lack of knowledge of the result, which is ultimately a measure of our lack of knowledge of the initial state.

So, the link says, there's no such thing as a "fair coin" or a "fair coin toss", only questions of whether observers can predict the state or not (this is mostly used to argue for Bayesian statistics as the correct way to view statistics, while frequentist statistics is considered ultimately incoherent if looked at in enough detail).

I was pointing out however that much of this uncertainty in actual physics is in fact fundamental, not observer dependent. Of course, an observer may have much less information than physically possible, but it can't have more information about some system than a physical limit.

So, even an observer that has the most possible information about the initial state of a system, and who knows the relevant laws of physics perfectly, and has enough compute power to compute the output state in a reasonable amount of time, can still only express that state as a probability. This probability is what I would consider a physical property of that system, and not observer-dependent. It is also clearly measurable by such an observer, using simple frequentist techniques, assuming the observer is able to prepare the same initial state with the required level of precision.
