> "My prior thinking had been that some kind of space dust could be causing the redshift. The same way we observe that sunsets and sunrises take on a red-orange hue, especially when there is a lot of dust in the atmosphere, maybe Hubble and Perlmutter were seeing the effects from space dust."

So much physics misunderstanding right there.

The red hue of the sky is from filtering by dispersion. The spectroscopy of red sunlight during sunset is similar to the spectroscopy of regular sunlight. You have same absorption lines. Just lower amplitudes in higher frequencies.

Redshift from stars moves the absorption lines. There are no known mediums which would have this effect after light left the medium. The only things which have that effect are gravitation and Doppler shift. Those are literally the two things astrophysicists take into account very well, leading to current theories.
What? Of course you can see it! Have you actually look at it?

FWIW, after looking into this a bit, it seems to me like that issue is only about as harsh as is warranted, calling someone out for pulling a fast one on their users.

Certainly, I would be shocked if anyone considered Karl Fogel to be some kind of asshole, and yet he can be found in the comments not only defending the premise but also defending the issue's anger.

My ISP in Ontario, Canada, has full ipv6 sorry for their cable customers, but tech support is clueless about it still. I had issues with ipv4 connectivity once and they struggled to understand that ipv6 was working perfectly and it was strictly v4 not working at all
There are a few conversions like this where I live (also in the UK) and I agree that the results definitely do vary. Where the conversion is in the heart of the city, it seems to work pretty well -- sometimes even better than knocking down and rebuilding, because the existing offices usually have stand-off space around the building that would be lost in a high density redevelopment. And from an environmental perspective, keeping all of that 1950s/1960s poured concrete in place has got to be a good thing.

What really doesn't work is the partial conversion of offices on industrial/commercial parks out of town. It seems to lead to completely incongruous buildings, dumped essentially in the middle of parking lots, without basic amenities such as verges and pavements. Those buildings tend to be flimsy, and it's hard to see the environmental argument for keeping them. I would rather see those sites razed and rebuilt as better quality housing.
Sounds like a spiral down— where low expectations of other people start to self-fulfill. Social bitterness is toxic — people will avoid it or disrespect it. It’s not your fault, but you should know that there are really good people out there… but bitterness, disappointment, fear and low expectations can make it really hard to develop positive relationships.

Many people (not all!) are willing to forgive and forget, so long as you don’t feel the need to dredge up past wrongs, but just focus on having good experiences together.

Hope things work out.

I completely agree about the value of isolation. You can update or up-rebuild for a new os version on one service at a time - which I find helpful when pulling in updated packages/libraries. You can also cheaply experiment with a variation on your environment.

Yes, you would get redundancy pay though the amount depends on the country and company and 6 months seems on the high end of the scale.

You don't need to have a competitive advantage to gain from trade. You don't even need a comparative advantage.

You think that trading electricity to the rest of Europe will let them take your manufacturing industry. So your plan is to pointlessly increase Europe's electricity prices by breaking the market mechanisms that allow trade?

That is not a good plan. It's not a good plan if you want to support local industry and it's not a good plan if you don't. It's just not a good plan.

At best, you could claim that there's nothing else you can do that would work, and so this bad plan is better than all the other worse options but frankly it's not a very convincing case.
I personally can’t find a reason to switch over on my home network.

I understand why v6 is necessary for the internet but I can’t reconcile it with my home network.

I tried a few times migrating over and it’s just an insane amount of work for essentially nothing… all the firewall rules, containers to subdomain mappings, all the wifi clients would get a completely new numbering scheme. And it changes when you change ISP if I understand correctly because your prefix changes.

It just seems insanely complex to me for no benefit. I have nginx as a proxy on ports 80 and 443 which dispatches the request to the right application based on the subdomain, and that’s it. I don’t understand what ipv6 would do for me in that context.

And most (all?) games or VoIP or other network applications all know how to deal with NAT by now.

With v4, I can have subnets and firewall rules so that my printer can only talk to local computers, or my tv only to my home assistant instance. Now idea how I’d move this all over to v6.

I'm about to start out on this journey. I graduated from university in the UK in 2002 with a mediocre degree result (2:2). That hasn't held me back in industry having various roles within organisations and latterly consulting roles and briefly consulting/contracting independently.

I've also had three years of not working due to looking after my children while my partner worked. That was incredibly rewarding and incredibly tiring. Now with them in childcare it's a great time for me to go back to university for a masters with the intention of finding a PhD place after that.

For me, the goal is to get more rewarding work. Personally, that means working for what I feel is a better goal that purely making money for a company owner. I plan to take a masters in Software Engineering and then use that skill to transfer to a subject in Earth Science (or similar) where I can use programming to fulfil research needs and hopefully continue in that vein for a rebooted career.

Luckily now I'm living in Norway means that a masters is free and as my partner works I can concentrate on study without needing to worry about money.

Advice from my thinking so far would be:
- know what your aim is. Education for it's own sake is great but if you have a different goal in mind then consider whether higher education is the best way to get there. If you know other people in a position you'd like to be in, ask them what the current best route to get there is.
- try and discuss with potential course supervisors in advance whether or not you will be accepted. With 20 years out of education, I've found it interesting to consider whether or not my industry skills will be valued as much as the school/university level education. I'm definitely not as sharp on lots of things but that experience does count for lots.
- if you're behind on what current "feed in" courses teach fellow masters students, sit in on lectures and read the course material as much as possible so you're not behind when you start.
- the academics I know love to talk about academia and are a great source of knowledge on the education routes that are open. Being an older student will probably mean you're better able to approach them and get this knowledge. Everyone I've spoken to has wanted to help so take advantage of this.

Good luck, hope you find the right route for you!
I went straight to work and didn't get to college until 41/42. I'm working on my undergrad and plan to continue to my masters. I've found it incredibly rewarding for two main reasons.

First, since I have a career already, I'm free of the pressure to go to school for career purposes and can focus on something I enjoy, which also provides immense value to what I'm doing every day (I chose philosophy, much more relevant and practical than I think many realize).

Second, I enjoy the experience and get quite a bit more depth from it than I would have in my 20's. It's a richer, more meaningful experience now that I'm older, have a strong sense of who I am, and am not put off in the slightest by naysayers or influenced by people's opinions of what I should or shouldn't be doing. I have more maturity now than at any other time in my life, and this has served me well in the sense of approaching topics with intellectual humility and just enjoying the process of knowing nothing to knowing a little. I do all the reading and then some, reading far and wide as well as doing deep analysis, writing all my notes, reviewing, and doing practice essays, and I enjoy every bit of it rather than seeing it as a chore.

So, some initial thoughts for you, hope they're helpful. The only advice I can give is to enjoy it, realize it's a wonderful opportunity, be structured and disciplined with your time, and use your hard-earned experience to your advantage.
If you don't mind, could you share the university you went? I dropped out my bachelors in final year, and kinda old now. Spending 1 or 2 year for masters is okay for me now, but don't want to spent 4 years for bachelors again. Trying to figure out options.

> edit: Obviously the electricity produced by the nuclear plants is used in district heating to power heat pumps but that is very inefficient (already ~60% loss just from heat -> electricity at the nuclear plant).

Well, heat pumps are pretty efficient, with a COP of ~3(?), the overall efficiency is better with heat pumps. Even better, however, is by combining both with cogeneration producing both electricity and heat for district heating. District heating in cities use the waste heat from the plant, and electricity can be used to run heat pumps outside the cities where the district heating grids don't reach. Of course the problem with cogeneration is that we have to get away from burning stuff, and siting nuclear plants in cities has its own challenges as well.
This may be true in many cases, but without more context for the question, it isn't helpful here.

> It's not clear which country you're talking about; land area of the USA is...

You assume that when someone just speaks of "the country" without specifying, it's the place where people think they're the whole world. I left it out to see if exactly this would happen because I was curious. I'm surprised not one but two persons felt certain enough I must mean the USA to correct my figure for the USA in a comment. Goes to show. My username is a city in Germany but apparently that wasn't enough of a hint that it is, for once, not about the USA. Also the USA uses double the energy per capita and has twenty times more people, 900 TWh should also be a giveaway for those who know any country's energy consumption, or at least it was easy to check that I didn't merely take a wrong km² value (also, I'm using metric).

Anyway, I'm glad we can supply global energy consumption this way. Now we just need a global government to distribute the produced energy to countries with higher population densities than the extreme examples you took like USA and Australia. That they can use solar effectively, both from the amount of unused land and favorable latitude, shouldn't surprise anyone. Oddly (no sarcasm here), I don't see them getting around to it either.

I just looked up the landuse of my country and that's about 7% built-up area. https://www.clo.nl/en/indicators/en0061-land-use-in-the-neth... Even if we cover all of that, it's not enough, we'll need to take land away from agriculture which is already only barely enough to feed everyone in a pinch despite having a huge yield per unit area.

Which is not to say we shouldn't do it. I just realized I might come across as "renewables will never work". No, with wind at sea and nuclear (easy to import from any country on Earth since it's so energy dense) we can be self sufficient even though we have enough independent neighbours that we needn't be anyway. It's just that the person I initially responded to wasn't far off, depending on which country they were talking about, and it's something people aren't being realistic about in counties near me. The reason that matters is that it influences policy: rooftop solar and wind are great, go go go, but don't stop there! Don't wait for that to complete, then discover we've replaced 2000's electricity use (not used for transportation or heating) and forgotten about the rest. That's what many countries are doing currently. See people being happy about headlines like "wind and sun were >50% of the energy mix last year!" when they really mean electricity mix and don't realize that this is about 10% of the total energy need.

As a person who manages a big fleet of servers containing both pets and cattle, the upkeep of the pets is nowhere near the cloud-lovers drum-up.

A server installed with half-decent care can run uninterrupted for a long long time, given minimal maintenance and usual care (update, and reboot if you change the kernel).

Also, not installing a n+3 Kubernetes cluster with an external storage backend reduces overheads and number of running cogs drastically.

VMs, containers, K8S and other things are nice, but pulling the trigger so blindly assuming every new technology is a silver bullet to all problems is just not right on many levels.

As for home hardware, I'm running a single OrangePi Zero with DNS and SyncThing. That fits the bill, for now. Fitting into smallest hardware possible is also pretty fun.
React with MUI is probably the "safe" choice right now. Getting good performance out of React when you have a lot of things updating in real time can be tricky but it sounds like you probably wouldn't run into that right away in an app like this.
pcwalton's problem is that he doesn't distinguish between different levels of memory safety. It might be "deeply problematic" for a language aiming for wide use in 2022 not to be make some significant efforts toward memory safety, but it doesn't have to be Rust levels. Rust itself isn't 100% memory safe, because a lot of code has to be marked "unsafe" even when it actually is safe and then it might contain other bugs completely unrelated to the reason for the marking and those might go undetected. Similarly, languages like Java and Python are even more memory-safe than Rust, but programs written in them are hardly bug-free either.

If you eliminate enough memory-safety bugs, then other classes start to dominate and should also be addressed. Rust is beyond this point, but to get there it diverted resources from addressing other kinds of bugs and has also made some severe usability/productivity tradeoffs. Zig might or might not be at that point, but it certainly promises to get there and to do so without the same drawbacks. Ultimately the question is which language lets you write more bug-free code per month. A reasonable argument could be made that it's Rust and a reasonable argument could be made that it's Zig. Only time will tell, but only if both continue to exist and evolve, which pcwalton and others seem unwilling to let happen. What's "deeply problematic" is their belief that Rust's goals and approaches represent The One Right Way and no others can be allowed to exist.

While I'm sure this would be great for your ego, it makes no actual sense. Very few documents from so long ago are available, not because it was somehow miraculously impossible to preserve documents but because overwhelmingly people don't give a shit.

You are demanding that future people should give a shit, and they aren't going to oblige.
A lot of universities have (often not well publicized) programs to help you finish bachelor's degrees after you drop out and are gone for a few years. You can sometimes get credit for work experience or other things you've done and take all/most classes online.

I went through one myself and am currently working on my PhD. If you have a relevant career or just come off as pretty mature a master's program will be happy to have you even if there were issues in your undergrad, but very few institutions worth going to will admit you without a bachelor's of any kind and the circumstances would have to be something truly remarkable.
