If you want to use microG as GMS replacement, it's impossible to do it without rooting. When application access GMS API, it will check the signature of GMS, so microG need some patch (Some ROM include it, like Lineage OS) or hook (e.g. via Xposed, like FakeGapps module) on system framework to return a fake signature for such a query.

Ok. Mark it as Open/OWE/WPA/WPA2/WPA3/802.1X. The main reason prevent old phone connect is WPA version. The newer WPA version require newer hardware and software.

Maybe mark it a compose of 2G/3G/LTE/NR, such as LTE only/3G+LTE/LTE+NR.
But there is another issue: the cell tower is belong to different MNO, so for some MNO you get 3G+LTE but for another MNO you get LTE.

Actually, Celeste is originally a 8-bit game. It was developed on PICO-8, and then was ported to PC.

RTL8159 is great. It's almost the only USB 3.2 (not USB4, not Thunderbolt) to 10GbE network card. RJ45 instead of SFP+ is a bit frustrating, but at least we can reach 10GbE without requirement for more PCI-E slot or USB4/Thunderbolt support.

There are some code updates to refactor API call two months ago on Codeberg.

OpenWiFi implemented a WiFi 6 (802.11ax) network card with FPGA, and its driver. Currently only available for subscription, but will be open source in future.

Because not all language and all users requirements is simple.

For example in CJK, we have too many characters (over 97k) to packed in one font. And we have many font style. So when put them together, we need to modify the font fallback list by user so users can make font at the right place to avoid some characters are sans-serif (Heiti), some are serif (Songti/Mingti), some are Kaiti and some are Fangsong. And in CJK, for same characters, it have different glyph in zh-CN, zh-TW, zh-HK, ko and ja. So we need different fallback list for different locale.

In Arabic and Urdu, the situation is worse. They use almost same characters, Arabic alphabet, but use different style: Arabic use Naskh, Urdu use Nastaliq. These two styles are very different if you only learned one it's hard to read another. So you must specify different font fallback list for different locale.

And it's not the end. Persian use Persian alphebet which is basically Arabic alphabet but plus 4 new alphabets. Unlike Arabic and Urdu only use one style, they use Nasteliq for poetry and Naskh for others. So just depends on locale is not enough for Persian, users need a way to customize font fallback list per UI elements, like CSS in HTML. Of course, it's so difficult to implement that only a few application support it. I write here here just to tell you the font fallback is a complex thing and it's impossible just using a simple per script list.

And the last issue is for all language users: it's hardcode, so you can't choose your favorite one. They said it's TODO to implement configurable default, but there is still no code, and I can't image the deal time of the configurable fallback list, and of further font fallback mechanism with font replacement features and font OpenType control features and so on. If they choose use wide-used Fontconfig instead of re-invent a square wheel, they can gain all these features with only a few code.

Maybe just run imapsync as a systemd service...

I think that most of usefulness of swap has passed now that we have systems with noodles of ram.

Please read this article authored by maintainer of Linux kernel memory management subsystem and cgroup subsystem, Chris Down.

And there is another article with some additional informations about swap authored by @farseerfc@sn.angry.im who tranlated the article above to Chinese.

Actually it's simple than "NAT", technically. Normally when we said "NAT", it's not just NAT (Network Address Translate), but a NAT plus a stateful firewall (see documents below). The conntrack here is a stateful firewall as in "NAT". And compare to create a map from (paddr, pport) to (iaddr, iport) and match the later, it's more simple to just match suffix of address.

No. It's not random. SLAAC uses EUI-64 by default, it generate fixed /64 suffix from MAC. And with suffix match of nftables you can still do device specific income firewall rules. For random privacy address, it's only used for outcome so just block all other income of IPv6 addresses except EUI-64 is enough.
