mrheosuper··on Why do we need human mathematicians anymore?
how can we understand absolute everything and still don't know how it work ?

mrheosuper··on Fixing an NZXT Signal 4K30 part 2: the green/pink video bug
> Claude also gave me back a command-line utility that reflashes the firmware using the DLL included with NZXT’s updater

This is surprisingly good. One of common question when RE is: How do we even read/write firmware.

mrheosuper··on Backups Aren't Simple
No, most(if not all) bluetooth controller has audio offload, basically the cpu does not involve(or very little) when transfering data from storage to radio.

Pretty sure that's the main point of Fuji camera, the output and built it filter is decent enough that you can upload to Social network without any editing.

Just check, my 2YO phone runs kernel 6.6, not latest but i think good enough for production.

Edited: I misunderstood what you mean, you were talking about the modem subsystem, sorry.

mrheosuper··on Backups Aren't Simple
And harm a lot too, you phone can't deep sleep since it has to wake up periodically to process data from bluetooth stack. Combined with slow transfer speed, that gonna eat your battery like nothing.
mrheosuper··on Backups Aren't Simple
Bluetooth is slow. The transport is 3Mbps at max, if you subtract all the headers from different layers, you may have like 1.5-2Mbps practical transfer speed.

That a good watchdog kick message NGL.

Does the image have bluetooth stack ? There is no reason to include bluetooth stack into the build.

I really hope those don't have access to any networks.
mrheosuper··on Small programming tricks
As long as they do that in separate channel and don't tag all, i'm fine with it.

As an average-techie person, the only piece of data that i truly practice 3-2-1 is photos and videos. 1 on my phone, 1 on my small server running Immich, and 1 is on Google Photo(sadly, the quality is loss, but i can live with that).

Most of other data i only have 2 backup, usually 1 at my local machine(code) and 1 online(github). Yeah it's not ideal, but another question to ask yourself, is it truly worth it. I trust the engineers at MS doing much better job at backing up their data than me.

Sadly after 22 years, it's still considered a "high-end" feature. Even on $1600 Fujifilm x100vi, there is still single SD slot.

Could your post some example result, so we can judge by ourselves

Brain is crazy. Recently i learnt that some people even don't have inner thought.
mrheosuper··on Linux from Scratch
You build it on your non-lfs computer. What is the other option?

And you dont need to boot anything, just a busy loop after a log "Hello World" is enough, if you feel fancy, maybe make a simple shell ?

mrheosuper··on Pion, an agent designed to run any company autonomously
you said like the only reason you can't learn new stuff is because of old stuff taking room. Do we even run out of memory?
mrheosuper··on Ubuntu 26.10 completes transition to Rust-based coreutils
> since I usually found oddities that they probably did not intend to be that way.

Or it could be you don't have the context like they did. Maybe some hardware bug/quirk that happens on some exotic machine that you don't have.

mrheosuper··on Ubuntu 26.10 completes transition to Rust-based coreutils
why bother with ubuntu at all ? If you want ubuntu but without snap out of the box, Zorin is 1 option. Or if you also hate gnome, linux mint.

mrheosuper··on JetKVM Mini
Hi, thanks for sharing.

Have you considered using usb-hdmi capture dongle instead of using hdmi-csi. That is my idea, you bring your own capture dongle, plug it in and good to go. The esp32-s3 (and P4 i guess) support usb host, and there is uvc example from esp-idf.

a 1280*720 frame, 16 bit, ping-pong buffer uses only 3.6MB of ram, still plenty of ram left for compression. The Keyboard/mouse component use like 512KB ram at most(even less, HID is cheap).

As long as it's not intended for user to plug in, it's fine. Many other vendors also do that.
