Rsync's worst feature is the slash rule: "A trailing slash on the source changes this behavior to avoid creating an additional directory level at the destination."

Every time I write the rsync command, I have to re-check it, it terrifies me if I get the rule wrong!

From purely software standpoint of view, why is faking phone's TPM so difficult in order for Waydroid to pass SafetyNet?

I'm even willing to hook old Android phone to PC to use as safetynet device, but I can't find people has done such yet.

Iptables still doesn't have a way to add a rule if it doesn't exist?

I know -C or --check, but it still requires us to repeat ourselves.

Why there is no microcontroller boards (like Pico, ESP32 etc) with deep-sleep and RTC module builtin? Every idea I have requires good low power deep-sleep and RTC to wake it up.

Why does Google Earth (web version at least) still doesn't allow locking the north? I spin the ball, and suddenly I'm upside down, it is frustrating.

I haven't tried to do webrtc yet, but interested. It requires some server, and now I wonder can I use Cloudflare's TURN server for discovery: https://developers.cloudflare.com/calls/turn/

Very few good examples out there for #WebRTC #JavaScript

Bought NVME <-> USB adapter, only to find out it probably doesn't work with Raspberry Pi properly. It detects and allows to write, but after writing for a while Linux remounts it as read-only, and I get huge amount of errors like "scsi host1: uas_eh_device_reset_handler start"

I'm trying to boot Raspberry Pi so that it writes entire OS to RAM. Examples of how to do it are extremely kludgy.

Why can't we just dd root to ramfs and switch/pivot to it? I've already tried one but pivot_root doesn't work if it's done on running system, it needs to be done before systemd.

What is this MiniPC segment:

"Asus Expert Center PN53: A powerful mini-PC with fan problems - Most things about this tiny PC are really good. But man, it's loud."

Why would you buy a loud MiniPC? You'd have to put it in a closet. If you have to put it in the closet, buy a real damn computer.

[#]Raspberrypi doesn't support kexec (ability to boot to different kernel / distro from Linux itself). I'd like to install multiple distros and do unattended switches.

I've spent few days figuring out what would a real computer (with truly passive cooling) would cost that can also support kexec.

NUC / MiniPC segment is terrible. Very few sites tell which one has vPro (support IPMI), which is fully passive-cooled...

Bluesky seems to have a surge in momentum among certain tech communities migrating from Twitter. Dan Abramov, who has long been involved in React, is building Bluesky and is surely driving traffic there from JS/React world. Another thing I noticed is that Kubernetes/Cloud communities have been migrating since Kelsey Hightower moved to Bluesky.

I would love to have a hackable smart watch. I've created my own Garmin watch face, but the limitations they put on the SDK / API is frustrating.

There is so much more I would like to do. E.g. setup alarms based on the calendar, show timers on the watch face, show wake-up alarms on the watch face, etc. They don't allow us to build these.

This weird need to control what you can do with your device isn't new, it was even before Apple. Even Nokia's Symbian was terrible at this.

TanStack Start's createServerFn, and React server components are very close to what you can do with Blazor in .NET.

It's so much easier for internal tools to not need a visible API.

Google Chrome's network throttling and latency settings don't seem to affect WebSocket packets. That is kind of annoying, as Blazor heavily utilizes that. How to simulate latency, is the question...

Bugs like, preventDefault not working make me think #Blazor is not the top priority for the ASP.NET team.

What sort of HTML-interfacing event handling API can have "preventDefault" from not working for a year or more?
