I am right at this moment letting a local chinese model (Qwen3.8 27b) update my build environment to mimic upstream build process changes.

Tedious secondary work which the tiny model does just perfectly (and more thorough than I myself would do it).

As the hardware is already available from other projects, that will literally just cost me some cents in electricity cost, compared to probably 20+€ if I would let some Anthropic model do the same work.

So I am really not surprised.
You just don’t need the latest frontier models for most stuff any more…

The devices in question all were fat formatted, for which it is quite easy to reconstruct most of the “deleted” content using readily available simple tools (which I did).
But that was some time in the past, nowadays most systems use some kind of base encryption, making it less likely to easily find something.
The phone, on the other hand, was just not doing a factory reset before selling it, but only deleting files (and missing stuff, like some mail folders) and not having a password-protection at all… 😬

Thing seems to be though, that OP did not use LUKS consistently, but mixed with unencrypted uses.
In this case, fast, file-oriented secure-erase (or just throwing away all the LUKS headers, if the remaining partition was encrypted) might miss the remnants of old unencrypted uses.
So, specifically in OPs case, I am not sure if there is another safe option than a full-device overwrite e.g. using dd.

some small percentage of the data will still be around, because they do overprovisioning.

That’s why I wrote “directly accessible data”. You are certainly right that safely erasing all data on SSDs is hard to impossible to achieve, but so is the read access to it.
That means if we disregard the drug distribution or similar scenarios, should be enough for the normal person.

But I mean secure wipe isn’t hard… It’s copy-pasting 2 more commands from the Arch wiki, compared to the dd command.

But it will take significantly longer (typically using /dev/random and multiple passes) without noticably increasing security for SSDs.

It will have also have the same possible write-speed-penalty issue as the zero-overwriting, but this won’t be OPs problem any more because he is selling the SSD.

Is anyone even likely to be curious enough to look?

Well, can only speak for me, but first thing I do.
I mean, you can never know which administrative scandal you might uncover…
I stop the moment I find private stuff, though.
Had that three or four times already, the only case I was considering doing something about it was a completely unsecured and unerased phone still containing a bunch of business emails that clearly were sensitive or even confidential stuff.
I just told the seller how he screwed up here, instead of making a bigger fuss out of it.

You don’t have to install anything on it, just connect it to a running PC and do a dd if=/dev/zero, that should be enough to get rid of any remnants directly accessible.
Unless you are part of a drug distribution organization, in that case just use a hammer, a microwave and a blowtorch.

First day on the internet?

After noticing your username, this now sligthly creeped me out. ;-)

Well, free AI training data.
Can’t blame them, would do the same if I was an evil mega corporation…

And just switching some cables only require personal climbing gear

Speaking of which: I visited the Kaprun dams last year, and the upper one even has its own integrated climbing trail where you can just climb up the wall if you like:

Do you have a link to the repository?
Just asking for a friend.

3 time as much as a valley installation did sound disappointingly meager, and I was about to comment so, until I read the actual article:
https://www.axpo.com/ch/en/energy/generation-and-distribution/solar-power/alpinsolar.html

Turns out, the heading and text snippet somewhat understates the wintertime production during the darkest months.
Look at this figure, almost flat production across the year, which is a huge thing:

But most importantly, it does not compare it to plants in the valleys, but to plants on the Swiss plateau, which is basically mainly flat and devoid of the usual very steep and shaded Swiss valleys.

So this is an unexpectedly great.
Alpine solar power plants for the win, as it seems!
