I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.
Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.
This is something HP should have handled.
If a bad update is rolled out then it’s the responsibility of the software maker partner (HP) and the distributor (Microsoft), not just one or the other.
Those laptops are THEIR products, not Microsoft’s.
Both Microsoft and HP have branding on their laptops and a responsibility post-sale for the reliability of their systems. Hardware, firmware and OS responsibilities are all party to this chain of failure.
His other videos seem interesting too.
Yes it’s possible to run them without resistors if you put them all in series and use a current limited power supply. That’s how some LED lighting products do it, just not common LED strips.
Common LED strips are designed for convenience over efficiency. You feed them 12V and you can cut them to any shorter length without worry. You can’t do that as easily with series configurations.
and a constant current supply will suffice for several strips of series LEDs in parallel.
Yes and no. I’ve seen lots of series-parallel products fail with blown LEDs.
For parallel LEDs to work you need three things:
These 3 things cost money so they often get skimped.
The LEDs will end up in an autonomous greenhouse where power efficiency is important.
Removing the resistors of a white 12V LED strip will (at best, in theory) increase your efficiency by 25%.
Choosing to use more LEDs and driving them at lower power levels might increase your efficiency even more than this. In 2024 you should be able to get well over 100 lumens per watt, but many LED strips overdrive the LEDs, dramatically lowering their efficiency. LED light output versus power input curves are very nonlinear, you get decreasing returns of light the more power you put in.

What are you growing? Sounds suspicious. Please don’t do anything illegal.
If your greenhouse is anything larger than a small test then please instead proper fire detection and suppression systems. Don’t get people hurt.

My family has a Chiq U58G7P. Warm boots take about 30 sec and cold boots a few minutes.
Don’t try and press any buttons on the remote during this time or for a minute or two afterwards. They might work, 15 seconds later, or they might get ignored. Sometimes your button press inputs get re-ordered too.
Factory resets do work, but then all it can do is broadcast TV. If you let it update and install streaming apps then you will be back to the same problems.
I suspect that it might be running out of RAM and thrashing some poor innocent MMC as swap, but I can’t find a USB ADB port to properly find out (maybe it has one internally?).
+1 to runit. So much simpler than systemd unit files.

Any other way to see this? Or is this show not freely available (ie you have to pay for it)?
Nice, ty. I’ve only revenged PC firmware, not embedded, so I wouldn’t think of several of those tools.
I know a model of HP inkjet from my childhood that had a service/factory mode where ink checks were disabled. After years of claiming that its carts were empty I was suddenly able to print perfect full-colour pages. RIP HP Photosmart 3110
Congrats :) The idea that a few software bits are between you and getting a pile of junk working is infuriating. Did you extract and modify an image from flash or find a way in live?
Ditto with my printer. Print over LAN: sure. Printer connect to internet: hell no, that’s the first-party version of printer malware.

Those security features are misleading.
A second app can already read all of your files, modify the first app, modify $PATH to replace your display server and do anything it wants as your user. Running wayland instead of Xorg provides no tangible benefits in security.

Summary: two Silicon Power P34A80’s died within a few months of use, the second one was the warranty replacement of the first. In both cases sectors suddenly became permanently unreadable.

Smart locks are worse. They have all the insecurity of a regular lock, plus more methods of insecurity, plus more failure modes that will shut you out of your house.

FWIW I was running “xbps-query -s gtk2” out of curoisity last night and only saw “gtk2-engines”, which I thought was odd.
Windows update fetches all sorts of things now. If the hardware advertises X device then Windows update will check if it has anything for it. Approved vendors can provide all sorts of guff. Historically that has included drivers that intentionally brick your devices. HP probably packaged up some software that updates the BIOS and got it into the Windows Update DBs.
