Days before the 2016 election, 538 (which Nate Silver founded and was leading at the time) ran an article titled "Trump Is Just A Normal Polling Error Behind Clinton". Nate Silver and 538 did some of the best forecasting of that election. Don't conflate him with others' screwups.
K-9 mail... isn’t supported or being developed any more.
That's not true. They make frequent-enough releases, they post monthly progress reports, and they are actually going to become Thunderbird's Android version.
Having said that, I almost switched to FairEmail because K-9 lacked support for some sort of authentication measure (which I no longer need), but that wasn't because K-9 stopped development.
Also worth noting this article is nearly five years old. Rust's first stable release was nearly nine years ago, so its (stable) age has more than doubled since then. I expect Rust would look a lot more mature if the article was written today.
At a glance, it looks like Aegis generates standard TOTP tokens, which means there's a lot of software that can do the same thing, so you don't need to emulate Aegis. I use pass-otp (an extension to pass), but that's command-line-only, and a lot to deal with if you're not already using pass. From a quick search, it looks like Keysmith and OTPClient are decent graphical alternatives. From another quick search, OTPClient is available in Ubuntu 23.10.
Edit: Re-reading your post, your issue is that you don't like logging in on your phone, right? But Aegis just provides the code, you should be able to use the code from your phone to log in on your computer. TOTP codes are only affected by the secret values and the current time, so the code generated on your phone can be used on any device.
You got this backward. The UK and US announced they would send depleted uranium rounds to Ukraine, and Russia lost its shit (Reuters, NPR, NBC, Al Jazeera). Why do you think Russia lost its shit? I think it's pretty apparent it's because they don't want the West supporting Ukraine and will latch onto any issue that could weaken that support.
Tell us more about what you're thinking of building/drawing. I like FreeCAD, but it's also quite complicated, depending on what your goals are.
Here is their reasoning, basically summarized as "it's easier to get everything for games into a new language than bolting it onto an existing language". I also recall seeing a blog post where they said their initial implementation of GDScrip took fewer lines of code than embedding Lua did.
Note Godot does officially support C# and C++, and there is unofficial support for other languages too. But they commonly recommend GDScript for beginners.
I've noticed that, if an equation calls for a number squared, they usually really mean a number multiplied by its complex conjugate.
