It's totally valid in most cases. It's technically only supposed to be used for a question, but language is based on how it's most commonly used, with those "rules" only applying in extremely formal situations. With the prevalence of informal text-based communication, many people use it to indicate being unsure, like how you used it. I just wanted to continue the chain of grammar corrections (which is why I used the wrong "its"/"it's" at one point). Also, you were right about the quotes.
A question mark does not fit the sentence, which is a statement ("they should." rather than "should they?"). While question marks are commonly used to demonstrate a rising tone at the end of a sentence, its not considered correct for formal writing.
Be extremely careful. Plenty of people are really smart and malicious, so you need to isolate it from everything on your network. You're giving random people remote code execution on your local network, which is like the worst case scenario for security.
If you're rooted, you can use Pixel Launcher Mods (or Pixel Launcher Extended, which includes Pixel Launcher Mods). It themes all of them but Libro.fm automatically, and you can easily add an icon for anything missing (either making your own or using one from another app).
A mirror? Light won't reflect off of nothing. The closest you'll get is gravitational lensing, but that requires about a galaxy's worth of mass to make any noticeable difference.
I used to have an older HP LaserJet, which was really good. Their more recent printers just keep getting worse, and I feel like they're coasting on their reputation. Brother laser printers are what I've found to be the best modern printers.
However, some applications don't work as well because of the sandbox, but I think this will change with the rising popularity of Flatpak, as more developers will use portals instead of direct access. Also, there are some bugs and missing features, like how heavy use of the org.freedesktop.Flatpak portal for dbus causes a memory leak (https://github.com/flatpak/xdg-dbus-proxy/issues/51), but it's overall pretty good. Most applications I use are Flatpaks.
Dual-boot, and if anything is missing, boot back into Windows to do that while you work on figuring out how to do it on Linux. There might be something to do what you're asking, but I find it unlikely because Windows and Linux are very different internally.
That's not really possible. With such a wide-ranging standard as USB-C, the cable needs to report what it can support. Without E-marker chips, for example, there would be three possible results: no cable can charge quickly, every cable is thick, short, and expensive, or cables catch on fire frequently. Cheap cables that don't support all of the extra features are just cables, but the good ones need to let the computer know what they are capable of.
Sorry. What I meant was that the project maintainers should do that, so the Discord users can use Discord but Matrix is still the main option.
