maxnoe··on String theory can now describe a universe that has dark energy?
Science never proves a positive.

You can only disprove.

The only way to prove a positive if there is a finite number of possibilities and you have disproven all but one. But even then, someone could conceivably come up with an alternate description that preserves the current understanding but makes additional predictions or is a simpler model making the same.

As Feyman said: "We can never know if we are right, we can only be certain if we are wrong".

maxnoe··on Astrophotography visibility plotting and planning tool
If you are more into doing this locally than using a Webservice, have a look at astroplan based on astropy.

maxnoe··on Some ecologists fear their field is losing touch with nature
If it disagrees with experiment, it's wrong.

maxnoe··on Time in C++: Inter-Clock Conversions, Epochs, and Durations
But on any modern CPU, clock speed won't be constant. It's not compile time constant, nor a runtime constant. Its variable over time. You'd have to record the clock speed over time and the ticks, so why not just record actual time?
maxnoe··on Avoid UUID Version 4 Primary Keys in Postgres
Would this argument still apply if I need to store a uuidv4 anyway in the table?

And I'd likely want a unique constraint on that?

maxnoe··on Rubio stages font coup: Times New Roman ousts Calibri
Fraktur is often associated with the German far right, because it's a mostly German thing that nationalists can hang on to.

Funnily enough, it was Goebbels who banned it and required everyone to change to Latin scripts.

maxnoe··on Python Data Science Handbook
The book is quite old actually, not sure if "this day and age" still applies to it
maxnoe··on CERN Council reviews feasibility study for a next-generation collider
Completely new tunnel, but it will be connected to LHC, as they will use LHC to pre accelerate the particles.

Almost all accelerators built at CERN are still active and are a chain of pre-accelerator for LHC now:

Don't forget the follow up

maxnoe··on Making Minecraft Spherical
> WGS84 sucks for mapping a sphere.

WGS84 is not a map projection, it's a geodetic reference frame prescribing a reference ellipsoid and reference positions of ground stations.

maxnoe··on NIST ion clock sets new record for most accurate clock
The idea here is to have a clock that actually ticks faster and to redefine the second in terms of that new, faster ticking speed.
maxnoe··on Turkey bans Grok over Erdoğan insults
Happened with real people too: https://en.m.wikipedia.org/wiki/B%C3%B6hmermann_affair
maxnoe··on LetsEncrypt – Expiration Notification Service Has Ended
Since my DNS provider(IONOS) has an API and there is a plugin for my Webserver (caddy), DNS certificates were completely painless, even for *.<my domain>.

The solutions exist, depensa on the providers and your client.

maxnoe··on Apptainer: Application Containers for Linux
This project is way older than (rootless) podman.
maxnoe··on Fujifilm X half: Is it the perfect family camera?
Author drops that he owns a Leica M11 in a half sentence.

Most people who consider prices don't.

maxnoe··on CERN gears up to ship antimatter across Europe
The anti proton was very fast, but it needs to capture a positron to become an antimatter hydrogen atom. This happens after the anti proton was slowed down.
maxnoe··on PyPI Organizations
Organizations cannot yet create tokens, only the setting up trusted publishing is supported, but that only works on four providers and e.g. not in self hosted gitlabs.
maxnoe··on Modern LaTeX
HTML + CSS is only half of the equation. The renderer is also important. So you need a layout engine that turns the HTML+CSS into something you can view.

Most of the time, this is one of the browser engines, but there are many more things.

There is e.g. weasyprint to produce PDFs from HTML and CSS, which would be the closest alternative to LaTeX taking HTML+CSS as input.

For simple documents, it's a much cleaner alternative, I used it to autogenerate documents in a python backend.

maxnoe··on Modern Latex
I've been using microtype with lualatex, fontspec and Opentype fonts for years.

What doesn't work?

maxnoe··on New atomic fountain clock joins group that keeps the world on time
The current goal is to redefine the second in terms of an optical frequency once clocks are available that offer a higher precision than 1 second over the lifetime of the universe.

maxnoe··on Chroma: Ubisoft's internal tool used to simulate color-blindness
Not for gaming, but this was developed for checking plots: https://github.com/hdembinski/monolens

And works cross platform.

maxnoe··on Neutrinos' maximum possible mass shrinks further
You can express rest energy in electron volt, a unit of energy. The energy an electron gains by being accelerated in an electric field of 1 Volt.

But since E=mc², you can say the mass is X eV/c² and then people become lazy and forget the c² or even define a new system of units in which c=1.

maxnoe··on Utah becomes first US state to ban fluoride in its water
Both. You get untreated, just with iodine and iodine + fluoride.

maxnoe··on U.K. orders Apple to let it spy on users' encrypted accounts
Please read Articles 1 to 19 of the German Constitution.

It's a worthwhile read for anyone.

maxnoe··on Seconds Since the Epoch
Sorry, there is a "not" missing there.

A remaining issue is that it is not easy to get proper TAI on most systems.
