I think just setting up Unbound is even less trouble. Servers come and go. Getting rid of the dependency altogether is better than having to worry who operates the DNS-servers and how long it's going to be available.

If you're worried about methane, then maybe you should look at the spectrum of methane. You'll be surprised...

That discussion on Stackexchange has something like 6 upvotes. And if you read it, the comments there are mostly ridiculous. The absorption is logarithmic beyond 8000 ppm, and someone there e.g. whines about that Wijngaarden doesn't explain the climate on Venus (> 90% CO2 atmosphere).

The thing about Venus is also something you'll find if you look for serious papers trying to criticise the paper. Nitpicking about the word logarithmic seems to be the only things that serious critics have found. The other main argument seems to be name calling and Cancel Culture... and that's all what critics so far have produced...

Claiming that things are unaccepted is also some kind of rumour. There are more papers, and if you read them you'll notice that they're of very high quality. Just compare the quality with that of papers of critics...

To me the most compelling argument for Wijngaarden is the incredible low quality of all the writings from people from climate-institutes that tried to find something against him. OMG...

1967 is pretty ancient... Nowadays there are databases and there are detailed calculations about the spectrum (line by line). There is HITRAN database. And people did the calculations. And have done so for years... There are pretty precise calculations how much energy is being trapped. And they fit with observations. There is a saturation effect, and it's pretty strong. On each frequency you can only absorb the total amount of energy that is available there. After that adding more CO2 won't make a difference.

People calculated precisely what exactly happens when you double CO2... And the effect it's logarithmic...

The spectrum still is like it is. Even Cancel culture won't change it. Please read some papers about the subject... I was pretty shocked to see what kind of quality you find there... (Nothing but a little bit of quibbling, and also a lot of name calling...). There is a reason why politics shuts down some institutions... Mainly those that have some kind of consensus, that doesn't have any foundation in physics. It's just a sect... Strong believes - and no science...

Or we should start reading books about atmosphere physics. Taking a look at the infrared spectrum and checking out what's really going on there is worth it...

China seems to have even more scales..

  myriad scale - based on 10.000
  mid-scale    - based on 10⁸
  long scale   - based on doubling of exponent (4, 8, 16, 32, ..)

Maybe it's not measured criticism, but that doesn't mean that something is true or false. Today there are serious problems with academia and criticism in general. Also Cancel-Culture nowadays is big.

I know enough good scientists that don't work in academia today. And I've seen a clan of religious nuts (like flat-earthers) working in bio-science academia. If people claim that academia nowadays is worth something I'd add a big "citation needed"...

For physics maybe there is some hope. I still know some good guys working there... But there is e.g. atmosphere physics... if you look deeply you'll find more failure there than non failure.. The rot for sure has already started...

The worst is probably Marocco DST

Calculating Ramadan is something software packages most likely won't do. To get the visibility of the moon correct, I think you have to know the exact location - and maybe check, if there is a mountain obstructing the view.

Germanic languages have special words up to 12. So I'm really surprised that the Babylonians didn't have a special symbol for 12. Something like that would have been really nice for a clock.

I think the ear relies more on resonance (unrolled it's like a stretched rubber triangle). The higher you go, the more it reacts on higher frequencies. This one here seems to just use passive reflection to get the effect.

Interesting, that it's all standard base-10. A Number system based on 12 could have been a good fit for a base-60 time.

Babylonians/Sumerians invented base-60, and didn't have special characters for 10, 11 (and maybe 12)? Really?

The essence is that each frequency alone is eventually saturated. (can't absorb more than everything). If you add more CO2 you'll start to absorb more in new frequencies, but the effect is getting smaller. To calculate how much the numbers add up, there is HITRAN-Database with a lot of data about the absorption lines.

About these calculations there's interesting material out there. I think there's even software to download, and feed with a download of HITRAN-Data.

If you look more, you'll most likely find more discussions. The things on StackExchange are a bit lame. There was a blog somewhere that posted about climate data for about a decade and had a discussion going on for maybe 2 months... I don't know if can find that again. Soon after the discussion of that paper the blog was pretty dead...

Mass Hysteria is seriously dangerous. A few years ago I've seen a full room of people applauding Military for ordering more tanks. ("Enough to have those shot down by Russia in the calculation"). And young German politicians being proud of it. They even said publicly "The best outcome of the Ukraine War would be reinstallment of the old German-Russian border."

Germany has the potential to go full Nazi again... And the population is mostly crazy in a scary way "We need sirens", "We need bunkers", "How can I make my pupils go for a career in the army"...

Instead of of investing time into making a mesh network. I'd like to see more energy spent on preventing real dangers. If people don't start going against the real troublemakers, loss of internet will be very low on the list of problems of the future.

And still nobody I've ever seen in public speak or comment about climate has ever read any paper on atmosphere physics... Before you build a mesh network against climate change, people should better read at least a few papers about atmosphere physics first.

Most likely it depends on what you want to do. I used LibreOffice a lot (mainly Calc). A lot of areas were surprisingly buggy, but in some important areas it had more advanced features than Excel and performance was great.

One thing I learned was, that there is no compatibility. You can load some files from Excel, but to get something done, it's better to start a new file from scratch and import the data from csv. As soon something is more advanced (like configuring an axis of a diagram) it's all different.

Most important - CSV-Import in Calc is something that works just fine in LibreOffice, while the CSV-import in Excel has always been hardly bearable.

Indeed it does, e.g:

Nice. Writing code is very different. People mostly seem to train English word-lists to increase wpm. But for code you constantly have to deal with new words, prefixes and special characters. Awkwardly placed special characters on the keyboard can ruin the flow. Dvorak, Colemak don't have any improvements over Qwerty - so they're most likely pretty useless.

Layouts with nicely placed special characters are all very non-standard. Building a custom keyboard nowadays is quite easy, but it takes some courage to train something that is seriously less standard than Dvorak ever was.

Maybe some people confused wpm and characters per minute... For writing software having 100% accuracy with numbers and special characters is more important than speed. I don't think 100 wpm is real for coding.

Performance is not a hack. Title is wrong... ;-)

Interfaces are indeed much nicer, but you have to make sure that your program language doesn't introduce additional overhead.

Don't be the guy that makes Abstract Factory Factories the default way to call methods. Be aware that there are a lot of people out there that would love to ask a web-server for instructions each time they want to call a method. Always remember that the IT-Crowd isn't sane.

Parametric modelling isn't really there in Blender, but Blender is too good to not use. And it is still improving at an astonishing rate.

For me Blender has all I need for creating Models for 3D-Printing. And if e.g. Geometry-Nodes get some more love in Blender, they could become a base for proper parametric modelling...

I now use PostmarketOS as a daily driver on the old standard Pinephone, and it looks good to me. After trying a few recent distributions PostmarketOS seemed to work best.

Before PostmarketOS I used Arch on a Pinephone Pro for 2 years, but I think it finally updated itself into oblivion... The software never reached a really stable state, but I was surprised, that it worked so long.

In the beginning of the PinePhone I think Mobian worked best, but the most recent version didn't look as good as PostmarketOS to me.

Finally somebody did it! Back in the day my attempts to write a game in SQL were thwarted by buggy query-optimizers. They cached my calls to rand() way too often although documentation promised not to do that.

I've heard, that this approach works very well with "troublemakers". Maybe this is the selection bias. For communication with less emotional non-troublemakers there's less demand for professional advice.

Yes. That's surprising. Community events for Free Pascal have been very healthy and growing. Some old people from the community have died in recent years, but somehow even more new people showed up. It's not big, but the community of Delphi and Free Pascal is very active.

CIEXYZ (CIE 1931) had the best brightness axis ever. But the hunt for the best color-axis seems to be ongoing. CIE 1960, CIE 1964, CIELAB/CIELUV 1976...

CIECAM02 CIECAM16 seem to be new iterations. Maybe those are good now?

Supermarkets also sometimes play with the light around the vegetables. Some areas have so much red in the light that you better take the items to a different area to be able to see if they are yellow or orange.

People were always tribal. You just call out a group to be evil. And it takes just a little bit of propaganda and people will ignore any rational arguments and start harassing a group.

Witch-hunts (last conviction in Europe was 1944), jews, communists, americans, non-americans, all sorts of religious groups, ... history is full of that.

One thing that changed recently is that nowadays propaganda is very organized and well funded. I also think there was a pretty calm period for a few decades (but only in certain regions of the planet). In the cold war period the tribes were very fixed and the evil was always far away, so locally not much happened.

I think Craig Bohren wrote in one of his books, that to get anything calculated and done the waves are all you need. Particles are nice for some kind of visualization, but they don't really help getting things done. I liked that.

Instead of particles I like to view the interactions like the forming of a lightning in a thunderstorm. The energy-field builds up, And at some point of contact the energy is being released in a single lightning strike.

What I still wonder is, if the interaction really depletes the energy-field instantly in a single point, or if there is more going on (on different timescales - maybe with speeds not related to the speed of light).

The Logarithmic derivative is also something that is surprisingly fundamental.

(ln(f))' = f'/f

In function theory you use it all the time. But people rarely notice, that it related to a logarithm.

Also the functions that have nice logarithmic derivative are a lot more interesting than expected. Nature is full of Gompertz functions. Once you're familiar with it, you see it everywhere.
