Making a web app is a mistake 9 times out of 10, particularly when dealing with larger datasets. Because you're in physics, you probably want to skills you're learning to be transferable into physics and data science in general.

I recommend starting with python (if you know it already, awesome), then checking out pyqtgraph -- there's a bunch of demo apps that come with the package and you can use those as launch points. This will be your gateway into pyqt/pyside and legit desktop application development. Later, if you learn C++, you can transition into Qt (and still use all the power of the toolkit and the skills are transferable), or into raw C++ which is amazing for numerical computing.

This sounds like the sort of infrastructure project the Linux Foundation should be supporting.

My third year thermodynamics course opened with a similar quip by the lecturer. Entropy is actually depressing. You can't fight it. You can't not fight it. It just wins.

I bet this is a falling out with Hasbro execs on royalties. BG3 royalties were a cash cow this year for Hasbro, pushing Wizards (as a division) to be quite profitable, while almost all other divisions in their company lost money.

So now the agreement is over, and Larian is like: we will own the IP on our next project instead of paying $90M to Hasbro... And fair enough -- they've shown they can kick ass. Hasbro is probably gambling that it's the IP that made the money, and not Larian being magic in a bottle as a developer. So they'll kick tires on selling BG4 to another studio.

BG3 will go down in history as the legendary game before enshittification. Larian will make a few great games that don't sell as well -- before selling out to a whale that dumps money on the owner's front lawn (see also BioWare). The devs who made BG3 will found indie studios and make cool shit for a decade or two. So the wheel turns.

I'm kind of okay with this. It was a reasonable take -- not a hot take or an incendiary comment or something. Mods using their power to shut down discussion -- expected on that instance I guess ;)

This is my first time getting any sort of ban on any lemmy instance. Now I just need to get banned on a right-wing server for some other centrist take, to keep balance in the universe ;)

How many of you have experienced this on lemmy.ml?

Somehow they included Great Salt Lake. It is a "great" "lake" ;)

But they left out Great Slave Lake, and Great Bear Lake because they don't know Canadian geography. ;)

I'm assuming I can polish the plastic on the headlights in my 2006 Toyota Matrix. I plastic is still "clear", but all the road grit over the years have pitted and fogged the surface. Any advice on material for polishing?

I remember it and was there, on the KDE side of it. Summarized half-remembered version.

Corel WordPerfect had been ported to linux late in the 90s and they got this notion that people only bought Windows to use MS Office. So if they made their own OS, people would buy it just to use WordPerfect. They had grand plans to take KDE and linux and package it as a consumer grade OS. The closest other competitor doing that at the time was Caldera, and they were seeing some success, so why not eh?

They hired two people to "fix" KDE. But the people they hired had no idea how open source worked -- how to interact with a community that functioned more like a meritocracy than a managed hierarchy. They showed up on the mailing list and tried to make demands -- work on this, fix these bugs, adhere to our standards for this other thing, etc. When KDE didn't jump to their whimsy, they sort of got annoyed and just decided to maintain a patchset or something.

The distro flopped hard. And it started with their management. They could have instead hired a half dozen KDE developers that were already contributing, started feature or bug bounty programs (like Google Summer of Code, which was great but came later), and possibly have pulled something amazing together.

Excellent question. From first principles: mars is about 1.5 AU from the sun. Using the intensity equation (inverse square law), Mars should receive about 1/(1.5x1.5) the amount of solar radiation, or about 44% on average.

Earth gets about 1400 W/m² hitting the top of the atmosphere, but most places on earth only see about 1000 W/m² after the column of air absorbs a bunch of it. Martian air absorbs almost nothing (being very thin), so you'd expect to see about 44% of 1400W/m² -- or about 600W/m².

A quick Google search for "mars solar intensity" shows a result of 590 W/m², so that is pretty close to accurate, from first principles.

So 60% as bright, if talking pure intensity. As you say, the human eye has a pretty responsive dynamic range, and this is quite an acceptable number.

For point of comparison, this is the difference between the sun at high noon versus the sun at 4pm for most of the world. On Mars, high noon would have a solar intensity more like 4pm on earth. No where close to your darkness experience with the eclipse.

Complete tangent, but alumina, aka aluminum oxide, is usually considered the second hardest naturally occurring material. When it is found in nature, it is given the mineral name corundum and is clear. But if there are some impurities in it, you can get colours. Red corundum is called Ruby, and blue is called Sapphire. In the beauty industry, the same material (mixed with magnetite) is called emery, and lends its name to emery board, and is used in nail files. In the tech industry, it's used to make the extremely scratch resistant coating on most modern phone screens (basically nothing but diamond will scratch it).

You have subscribed to alumina facts. I'm sorry, the cat facts guy was busy.

When fascists say they're going to do something, it's probably a good idea to believe them. When they say they won't do something, they'll probably do that too.

When I was part of the KDE marketing working group, we always talked about 5% being the magic number. If we hit that, then the avalanche of ported and supported third party software starts. It's a weird chicken and egg thing. Looks like we're close!

Utility corridor. Sometimes a "Right of Way".

Depending on where you live, "hydro lines" or "transmission lines" or similar.
