We took a walk around campus after lunch, and are now looking at some old computers in the library's basement. 🥳✨💾

I am, yea, I do the recordings; heading to campus in a bit for a setup check. I'm at the Ocean Island Inn.

AMI has been the largest "independent" firmware vendor for quite some years.
One competitor was Phoenix, just acquired by Lenovo.
Only Insyde is left, having grown again over the years.
Those were the big three; all their stuff has been proprietary, NDA-driven business behind closed doors, providing barely acceptable (or worse) firmware for almost all laptop, server and desktop systems.
So now it's time for smaller firmware vendors to grow and provide better quality services.

Woah, no idea what to think of this yet; I'm curious what's going to happen.

Also, it's just based on @npub1sj2…2drf 's work, and he gave many really good presentations.
Stick with the original, folks.

I'm seeing/hearing this more and more often. 🧐
Which one do you prefer, are you a native speaker? 👈
Note that I'm not asking for being grammarist here.
I know which one is "correct".
This is about shifts in language, dialects, etc..

Thank you so much! I'm gradually adding more notes to my repo, including those references.
🗺️ Map all the things! 🧑‍💻

2026-02-19 13:47:26 CET

Idea: map of conferences
Some people track conferences they want to attend in calendars.
What if you could also explore a map to find interesting events nearby?
Markers would have a link, an icon and a label.
The link could point to a calendar entry in turn.
I bet that already exists somehow, but I don't see it much.
E.g. the Rust website could have that for all Rust conferences.
Or CCC for all the hacking community events in Germany.
DebConf, which moves around, to keep track of that history.

what's up with the seventh Tux? Is that a core on hold or one that failed or smth?

2026-01-02 16:58:39 CET

I think we're not far away from that.
LineageOS et al already show that building AOSP is generally feasible, though it does require at least 64GB of RAM, some terabyte(s) of storage and best lots of processing cores/threads (last time I checked the AOSP docs).
Plus, some vendor kernels are really messy; the Amlogic one for Android TV (in Google's own repos) had a few hundred #if AMLOGIC instances, even in mm/ when I checked about two years ago. 😅
Maybe upstream is complete enough now.

RE: https://infosec.exchange/@briankrebs/115826000254101154
Let's see about this.
I'm a bit too dizzy for now.
After a quick skim, this is just another "shitty TV boxes are shitty TV boxes" (idem picture frames).
No numbers, no IoCs, from what I read here.
A lot of text, but I'm not seeing the news.
Addendum:
What would an "unofficial" Android TV box even be?
Do you need Sundar Pichai's blessing?
Anyone can just build one, given a platform capable enough.
Such as, repeatig myself, the usual Amlogic, Allwinner and Rockchip SoCs.

The labeling should not mislead you.
There may be such botnets and the devices are of horrible quality, but just hating on China is too easy. That's all I gotta say here.
As y'all know, I have taken apart and looked into hundreds of such gadgets, including cameras and TV boxes.

As easy as it is to hate on China, let's please recheck. They are behind their firewall that renders anything unusable or at least close to unusable that is connecting from outside to inside and vice versa.
Not that cheap TV boxes are to be expected high quality, that is.

When I looked into IP cameras a few years back, seeing that merely a few chip vendors are involved and tons of whitelabeling businesses exist, at some point I read about "#racial detection" and such.

That was a weird one, obviously scam.

structs are a bit annoying to reverse, especially when they are passed around like there's no tomorrow, and in part they track state, in part they refer to peripheral registers... x)
