• You can use imapsync to sync all you mails from GMail to your new email provider if you still use email.
• If you no longer use email, Piler is a bit heavy but well-working solution.
• Notmuch is much lightweight but has no web UI, but if it require you install a (may be TUI) software, why not just install a mail client like Thunderbird and then just use its local mail feature to index the mbox?

They are totally different format: different structure, different keyword, different time date format, different escape way, different language specifying way...
Their common parts are only both used for feed and both use XML.
And even more, interoperability of RSS 2.0 itself is horrible, RSS 2.0 standard left too many details in not specified situation, such as how to deal with relative URL...
For more infomation, you can read https://www.intertwingly.net/wiki/pie/Rss20AndAtom10Compared

Unfortunately, IIRC, some feed readers only support RSS, not Atom. Those users may see some warning like "invalid format".

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.

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.

ESPHome has supported Thread since 2025.6.0b1. But Matter support still need more time.

For example, something like epub is going to be hard because the format is really just a zip file with a specific internal file structure. So, it's not really the .epub file you want to grep, but one of the files within that zip file you want to grep through.

ePub is a zip file contains a batch of HTML file for contents and some XML files for metadata. So you can extract it and do grep as you do for HTML files.

So when they will change this horrible hardcode font fallback list with "normal" font fallback mechanism like Fontconfig?

I suppose displayport over thunderbolt plus embedded USB hubs in computer monitors gets close, but the display settings controllers usually require proprietary drivers and are vendor specific.

DisplayPort have DDC to control display settings. But I don't know how much settings was standardized and implemented by vendor. But at least, the backlight was implement by most vendors, many users use it.

It's difficult to have. The members of HDMI Forum are almost the TV manufacturers and the members of VESA (the maintainer of DisplayPort) are PC and GPU munafacturers. So TV almost uses HDMI and monitor almost uses DisplayPort.

The green PCB on left-bottom corner breaks the consistence of design...
