adornKey··on Why is Venus hell and Earth an Eden?
Although there's very little information about the most interesting part. What did they use for their modelling? The results suggest somehow that the modelling includes a lot of manual handwaving...
adornKey··on How can I influence others without manipulating them?
...by showing them a lot of Comic Sans - that will blur their vision and weaken their defense a lot.
adornKey··on How can England possibly be running out of water?
More likely they'll hand out laxatives and ask people to help solve some fertilization crisis out there in the fields...

And there'll be commercials - Scotland - Heavy rain (horizontal) - A woman totally drenched (with baby in hands) - In panic - Warning about the impending water crisis.

adornKey··on How can England possibly be running out of water?
In Germany water consumption shrunk a lot, but here we also have a lot of talk about a water crisis.

Another news article recently made a huge story, that we're running out of sand. I wonder what will be next.

That sounds promising. Training muscle memory for a custom arrangement of keys is something I'm not (yet) brave enough to do. Did you arrange everything yourself?

Normal Arrow-Keys on a layer are good. But I need Arrow-Keys usually in combination with Shift and Ctrl. (move to start, end, next instance, declaration, implementation, Select something). This is already overloaded a lot, so I'm not sure, how well this works with a layer.

The thing that's missing for me most are those function keys. I need them a lot - sometimes overloaded in combination with Shift and Ctrl. Those actions are usually something that should be out of reach from normal typing (Terminate something, start a Compiler, mess with Breakpoints, ...).

Those small keyboards never include function keys. But I think I could just build something for that.. Custom button-Panels with a few keys are quite easy to make.

On the other hand there is spatial memory. Overloading things has some downsides - it adds more possibilities for errors - and makes muscle memory complicated.

In a lot of software those extra function keys are well used, easily go into muscle memory and help to safe a lot of time.

adornKey··on Untangling the myths and mysteries of Dvorak and QWERTY (2023)
Less things to connect, less switches, less caps, ... I think it's mostly about manufacturing cost. If you build a keyboard yourself, you're glad if you have to solder less. So for sure any prototype of a new design will start small. If you go full size price goes up a lot.

For usability alone those small sizes don't make much sense in an office or on a desk.

I think having Shift available for the thumb would help a lot (in the middle just below Space bar).

Most experimental layouts that add more features make the mistake to overload it, some of these things even look totally thumb-driven.... This make everything very confusing. Just Shift for a start, would be good. The pinky is too much overloaded. Offloading some of it to the thumb would actually be an improvement.

adornKey··on Stone Age settlement found under the sea in Denmark
I've sometimes witnessed newsworthy events. It was very interesting to see what media made out of it. Local news was very inaccurate. In Big papers the stories were more like fiction - using some fact from the real event as inspiration. It was surprising that local papers can't even get simple local news right. Only once I think the local paper got into a little bit of trouble. They wrote some nagging critic about the performance of some school theatre - but the event had been cancelled...

I think it is safe to say that using newspapers to wrap some garbage is where their real value shines. Reading the garbage wrap is something that people do, but I wonder why?

adornKey··on A failure of security systems at PayPal is causing concern for German banks
South Park once had a good scene about just not accepting random things that pop up (in HumancentiPad). If you see something popping up on a website - maybe just delete the pop-up from the HTML. (Click on Inspect - Examine - Delete).

Heise is a bit nasty with technology, and it's a bit harder to get rid of their thing, but I can read everything without accepting anything.

adornKey··on Scientist exposes anti-wind groups as oil-funded, now they want to silence him
There are some German guidelines for building offshore windmills - how noise should be reduced - and whales should be distracted and that ramming shouldn't be too loud. Most likely this doesn't come from nothing. So 100+ whales could be true, but I think all this is related to noise from construction.

adornKey··on Scientist exposes anti-wind groups as oil-funded, now they want to silence him
I don't know about those groups, but the arguments I saw so far are these:

   - Unclear maintenance - there's no clear way what to do with dysfunctional mills on land. 
     Just letting them rot seems to be a thing. Offshore maintenance is surely no fun, too. How long do they last?

   - Pollution - there's a lot of abrasion and this stuff is pretty unclear, 
     it's even going into places where clean water is collected. Does anybody care about this?

   - Ecology - there are a lot of trees that get cut down for wind. Maybe keeping those trees would be better. 
     Kills birds and bats is also part of the argument

   - Economy - a lot of energy is produced at the wrong time. So much that it's even expensive to dump.
     How much energy goes into producing the mill, and how long will it last?
     Does this break even if you subtract subsidies, maintenance and value the dumped excess-energy realistically? 
     Is there any good storage solution coming - or will this remain to be a myth?
 
In the end Economy is most likely the only thing that matters. But I guess this is not looking so good - if it would be looking good you'd see more logos of big energy companies on all these mills...
adornKey··on Why do people keep writing about the imaginary compound Cr2Gr2Te6?
Well, I did.. But that didn't matter. Nobody else did... And authority just declared himself as the winner. When they collected money I wrote a note and attached it to the "call for collection"-letter. I think there was some kind of group-psychology thing going on... I talked to a few people, but they just shrugged.

I learned from this that once group psychology kicks in most people aren't even able to look up mathematical definitions in a book to decide something. I wasn't interested in winning alcohol, so I didn't fight more.

Later I successfully corrected another professor, when I saw him making the same mistake... The only difference between the two cases was my tone and voice how I confronted the professors with their mistake. (For the first I was friendly - "Maybe check your terminology" - that didn't help. For the second I was more dominant and just told him that his terminology is wrong - that one worked).

Although I still wonder if the last guy really looked up anything in a book. Maybe with the right kind of authority in my voice I could have sold him any name for the Tensor-Product...

adornKey··on Why do people keep writing about the imaginary compound Cr2Gr2Te6?
This reminds me of a story from University.

In Quantum Mechanics the professors of my University consistently confused the terms Tensor-Product and Direct-Product. They all taught in lecture that the Tensor-Product was called "Direct-Product". In Mathematics this is just wrong. The definitions about what is what has been clear for about 100 years...

I called them out on that. The end result was, that the professor offered a bet in front of audience that he was right. The thing was simple - you just have to look up the definitions in any mathematical book. But nobody did this... Next lecture the professor declared himself the winner of the bet. The audience collected money. And on the next big student event they presented him a bottle of some nice alcohol as a price for his win. (They stopped Music for the party and made a big event about handing him the bottle)...

I learned that in University people aren't even able to look up a mathematical definition in a book... Nobody cares, especially those students that like to organise things don't - they surely meanwhile have made career as big heads in University councils...

Solution of the confusion I think was that in the beginning of QM the terms in mathematics were not so well defined yet. In 1910 Physics people most likely copied some wrong terminology - and some of it most likely can still be found in footnotes somewhere in physics - or in some oral tradition of local groups of professors.

adornKey··on What is a color space?
The article skipped a bit on explaining the CIE-XYZ space. Although it is quite simple.

There is one axis Grayscale - that gives you the Brightess value. You can use that for black/white TV.

Now for colour you have 2 dimensions left. For these you pick one axis, where the eye is most sensitive - and perpendicular to that you have one axis, where the eye is least sensitive.

This colour space is the oldest and all axis there make sense. You can easily compare brightness, and you e.g. can assign more bandwidth to the sensitive colour axis if you want.

adornKey··on What are OKLCH colors?
The best axis for Lightness in my opinion is still the Gray-Scale (as used back in the day for black/white/grayscale TVs).

The newer CIE colorspaces (CIECAM02 CIECAM16) seem to address the effect, that color-perception goes wild if you change background and illumination. Oklab seems to only make some fixed choice about how to include the chromatic part to lightness. I'm not so sure, how this definition of lightness is any better than grayscale (from 1931).

adornKey··on Sütterlin
Sütterlin is very ancient. I knew someone how used it for handwriting, but there are only a few people that really learned to read and write it.

In Algebraic Number Theory it's quite common to use some kind of Fraktur-Alphabet for Symbols (Rings, Ideals, Groups,...). It's natural there to use some kind of Sütterlin for hand-writing and exercises. But I think to become really fluent, you have to dive very deep into Algebra... There are some letters you'll use a lot like p(rime), M(odule), G(roup), R(ing), A(lternating Group), S(ymmetric Group). I don't think I've read/written all available letters yet...

adornKey··on When DEF CON partners with the U.S. Army
So far I haven't met anyone there who was into politics. People there are sometimes slightly anarchic, but definitely not interested in any left and right. But there are a lot of furries - the biggest visible group of visitors - they're just there for sex and party.

As far I can tell only some of the organizers (the people with the money for equipment) seem to have some ties to the fascist left. (Nowadays called Europe Socialism - they absolutely don't like Europe Socialism being called National Socialism - Europe is absolutely not National... But they don't really do anything that looks like CCC - they just spend some money there - and put a little bit of fascist propaganda on display...

adornKey··on I tried to replace myself with ChatGPT in my English class
Rushing is not good. Some People with good results started early and spent a lot of time reading transcripts of oral exams - and copied homework from other people. Some of them are professors now.

If good results are important, it's most important to know what happens in the exam - and adapt professionally. Learning is fun. I myself always did a lot of homework. But I wish I had been more professional - constant challenges are fun, but most of it is not very time-efficient.

adornKey··on Scientific fraud has become an 'industry,' analysis finds
To me it's quite simple:

  * If there's no clear way to get the raw-data 
  * If it's unclear how the data was gathered   
  -> the results are most likely fabricated
One strange psychological effect I've seen is that especially in medicine some people themselves spend a lot of time rigging data to get to their PhD, but in the end they absolutely trust in anything published in the field. "The science nowadays is so good - medical scandals today are completely impossible"
adornKey··on I tried to replace myself with ChatGPT in my English class
In my experience (about 2 decades ago) in a group of 20-30 students only 2 or 3 are able and willing to do homework. Most students just find someone else and copy from them. The real learning happens when preparing for a big exam.

And to pass an exam students have to prepare for the exam. Homework will only help there if it is similar to the exam.

One time I had to evaluate a written exam where the professor had set up a trap. There was a question that looked like a standard question from homework, but if you used the standard-techniques from the course your calculations didn't work - it was a nasty special case. Most people that started with that question just burned 30 minutes without getting anywhere... a lot of students failed, but at least they learned something about life...

And Oral exams are different. Giving a quick well prepared answer and being able to solve difficult tasks over a few days are completely different skills. Students there prepare for the professor. There are transcripts of previous oral exams. And professors change over the years - the final tough question of an excellent student will a few years later become a starting question. People that didn't know that game and didn't have access to any transcripts were in serious trouble... None of the Homework would have helped in the oral exam.

On the other hand especially the technical community is very quick with censoring anything new about climate-modelling. There has been a lot going on in the last 5 years, but knowledge about any of that is very low. Even Institutes like NOAA still promote models based on very old approximation formulas (Myhre et al 1998 - logarithmic approximation of radiative forcing).

Anything newer - proper line by line calculations that get rid of the approximations and take a serious look at the absorption spectrum - is nowadays essentially a taboo...

This subject is also a wonderful example why the maximum of a densitiy function has very little meaning. The amount of energy is an integral over the densitiy function, and if you look at the solar-spectrum, you'll notice, that the bulk of the energy is in the infrared.
adornKey··on Cloudflare 1.1.1.1 Incident on July 14, 2025
Having a 2nd trustworthy router consumes extra energy, but maybe it's worth it. More than once my router made an update and silently disabled the pi-hole.

Having a fully configured spare pi-hole in a box also helps. Another time my pi-hole refused to boot after a power outage.
