I remember that name from NCSSM! Cool to see you on the front page of HN.
We should catch up some time, it’s been ages!

The Internet seems rather reluctant to explain what exactly "pixel cleaning" does, but based on the vague useless "explanations" I could find, I suspect it's a sort of "flat-field correction" where it calibrates the pixel drive current to darken the less worn and/or brighten the more worn ones so it eliminates the burn-in effect. This obviously leads to a vicious cycle where more worn pixels are driven harder and hen…
If OLEDs are 'designed to fail' they've certainly gone about it in a very roundabout way - there would be much easier ways to do planned obsolescence if that was actually the goal of display manufacturers.
I have a LG wallpaper TV 65" from 2021. I see no burn-in whatsoever. Once in a while it says "we will do the pixel refresher thing when you turn off the TV".
I'm pretty sure there's something to it but I'm no expert. Five years later and my TV is just fine.

#133Any intelligent powerful person should be going entirely offline now--if I had net worth over $10mm, I wouldn't own a computer--I would have a secretary control my computer for me. We're going to see really horrible, persistent blackmail in the next few years destroying lives and reputations. It will eventually be the end of the consumer internet.

I guess this is a fine reply but just seeing your earlier comment, mentioning there are tons of glitching tools out there, I would've hoped to hear about some specifics here. Just my 2c
Is this the zoomer syndrome I am hearing about lately? My friend says zoomer coworkers increasingly start asking easily searchable questions, and also (this part is not your comment, just my 2c) in a demanding tone like you owe them money. Allegedly they spend all their time in LLMs and lose the ability to gather information I wonder what humanity will look like in 20 years if this doesn't stop.
I have encountered this behavior in people of all ages for as long as I can remember.

#135As FW engineer, I am both horrified and intrigued. The fact that there are so many devices lack even basic security features horrified me. A webcam that activity light can be turned off remotely, that's a big no no for me. But the use of LLM is also very interesting, we may put LLM in the loop to harden our devices. Sorry community, but it's our job to make the reverse engineer harder.
If you can use a custom chip yep, if it's commodity hardware probably not. You could use secure boot/secure memory etc but that can be a footgun in itself later.

#136Built custom firmware for my Line 6 Pod GO HD guitar multi-fx the other day. Turned into a complete midi controller so it wasn't gathering dust. Fun times!
Re: Everything I own, owned
#137Using LLMs for RE and bug hunting is a lot of fun. Today I reported an absolute doozy of a bug to Google's VRP. The vuln was in an HTTP API endpoint I don't have the source for, only RE'd client logic. The idea behind the bug was mine, it was of the "surely they weren't stupid enough to forget to do xyz" variety. Writing the code to probe for the vulnerability by hand would've taken a few hours of grunt work, includi…
I find whenever I do this I run into the bullshit cyber guardrails. What model are you using and how are you prompting it?
Re: Everything I own, owned
#138Two weeks ago I told Claude “I have a on the LAN at . Assume direct control of it.” And about 8 command approvals later I had a new firmware running on it. Mind you, it found and used an existing firmware flashing library for this family of devices. But it felt amazing to do in 20 mins what would probably have been hours and hours of research and tinkering that I wasn’t interested in. I just wanted a WiFi lava lamp.
Surprising. I have hit its BS guardrails a lot lately, working on my vintage computers from the 80s and early 90s. Just about done with Claude.
I’ve been doing this with Qwen 3.8 27B with success. Kindle, Android Tablet, and Raspberry Pi all working better and fully owned thanks to agentic help. No issues with hitting the guardrails here ofc.

#139> I can’t help but think about what an AI-equipped automatically-reverse-engineering worm could do today.
Everyone should read Daemon and Freedom, like right now.

The preceding sentence is equally prescient: > Operating systems aren’t really equipped to work with the user to ensure that a microphone stays a microphone, and doesn’t spontaneously turn into a keyboard that hits Win+R and drops a payload to steal all your data when the room is quiet enough that it can assume you aren’t watching. In a world of USB-C everything we no longer have power supplies that are physically bo…
Was daydreaming the other day about how this could be used by adversaries to hack even air-gapped computers. Any peripheral which contains a microchip and some ram is a vector. Does the compartmentalized facility ever bring in a new monitor, or mouse, or keyboard? All of those things could be hacked to hack their new host. And then taking data into/out of the facility. Which devices have lights? Any LED that can be b…
In environments where the threat model requires it you can/must already buy hardware variants that are non-radio. It's not just disabled in software but is a different physical SKU. Likewise data diodes for USB, audio, or display connections are also common.
The novelty is the uniform adaption of USB-C for the rest of the world and the endless attack surface that provides.
