[Windows subsystem] for [executable environment] is the naming scheme. The default is Win32, there’s one for POSIX (practically never used), and Linux runs in another.

This affects the view of posts via the bluesky servers, but not via mirrors or other servers

And the use of content addressing means you can be sure it hasn’t been modified

Several Android manufacturers have their own settings in the OS for battery longevity (automatic schedule based smart charging, or charging limits)

Don’t think it’s native in Android. Charging limits need support in the charging controller chip, plus driver support in the OS.

I use my backup headphones when my Bluetooth headset has run out of battery

Wireguard is most reliable in terms of security. For censorship resistance, it’s all about tunneling it in a way that looks indistinguishable from normal traffic

Domain or IP doesn’t make much of a difference. If somebody can block one they can block the other. The trick is not getting flagged. Domain does make it easier to administer though with stuff like dyndns, but then you also need to make sure eSNI is available (especially if it’s on hosting) and that you’re using encrypted DNS lookups

The only things I’ve ever heard of doing that is in very high security corporate environments

Your workaround is precisely why I said “more practical”. Any updates to your tooling might break it because it’s not an expected usecase

You don’t want FIDO2 security tokens for that, use an OpenPGP applet (works with some Yubikeys and with many programmable smartcards). Much more practical for authenticating a server.

BTW we have a lot of cryptography experts in www.reddit.com/r/crypto (yes I know, I’m trying to get the community moved, I’ve been moderating it for a decade and it’s a slow process)

The Nyquist-Shannon sampling theorem isn’t subjective, it’s physics.

Your example isn’t great because it’s about misconceptions about the eye, not about physical limits. The physical limits for transparency are real and absolute, not subjective. The eye can perceive quick flashes of objects that takes less than a thousandth of a second. The reason we rarely go above 120 Hz for monitors (other than cost) is because differences in continous movement barely can be perceived so it’s rarely worth it.

We know where the upper limits for perception are. The difference typically lies in the encoder / decoder or physical setup, not the information a good codec is able to embedd with that bitrate.

Newer fractional arithmetic encoding can get crazy

Why use lossless for that when transparent lossy compression already does that with so much less bandwidth?

Opus is indistinguishable from lossless at 192 Kbps. Lossless needs roughly 800 - 1400 Kbps. That’s a savings of between 4x - 7x with the exact same quality.

Your wireless antenna often draws more energy in proportion to bandwidth use than the decoder chip does, so using high quality lossy even gives you better battery life, on top of also being more tolerant to radio noise (easier to add error correction) and having better latency (less time needed to send each audio packet). And you can even get better range with equivalent radio chips due to needing less bandwidth!

You only need lossless for editing or as a source for transcoding, there’s no need for it when just listening to media

SMTP?

Except Opus. Beats it at most bitrates

You literally can not distinguish 192 Kbps Opus from true lossless. Not even with movie theater grade speakers. You only benefit from lossless if you’re editing / applying multiple effects, etc, which you will not do at the receiving end of a Bluetooth connection.

That’s more than a codec question, that’s a Bluetooth audio profile question. Bluetooth LE Audio should support higher quality (including with Opus)

Nobody needs lossless over Bluetooth

Edit: plenty of downvotes by people who have never listened to ABX tests with high quality lossy compare versus lossless

At high bitrate lossy you literally can’t distinguish it. There’s math to prove it;

https://en.wikipedia.org/wiki/Nyquist–Shannon_sampling_theorem

At 44 kHz 16 bit with over 192 Kbps with good encoders your ear literally can’t physically discern the difference

Transparency is good enough, it’s intended to be a good fit for streaming, not masters for editing

Transparent or indistinguishable lossy compression are other common terms

There’s a push for Opus now, it’s the perfect codec for Bluetooth because it’s a singular codec that fits the whole spectrum from low bandwidth speech to high quality audio, and it’s fully free
