Lots of comments are also massively overestimating the amount of time/effort that creating this setup required.

The new latest version (commit 806789e4d454b, 307 bytes) should also work. It no longer sets p_memsz to something unreasonably large, which was most likely the issue with the 301-byte and 298-byte versions from a few days ago.

I fixed the most likely culprit now (excessively large p_memsz value). It cost a few bytes; the new executable size is 307 bytes.

Looks like I may have stretched what values are acceptable for p_filesz/p_memsz too far. What's your kernel version? (I tested it on 6.8.0 and 4.4.0.) Perhaps the 316-byte version at commit 451827cfd5399074 (before that particular hack was introduced) would work.

GP is likely referring to how fields in the ELF and program header are abused for instructions and data in a way that happens to not break things on Linux.

If the savings are about `mov $1, %edi` and `mov $10, %ecx`, those 32-bit immediate values line up with the higher bytes of p_filesz and p_memsz in the program header, which have to be zero [1]. If not, what are the savings? :)

My terminal "warns" about them thanks to using a bitmap font that has no (significant?) Unicode coverage beyond code points 0 to 255.

This seems like it would be great together with a pair of display glasses (like those from XREAL, for example). But I wish it had a TrackPoint.

Sad to see GPT-4.5 being gone. It knew things. More than any other model I'm aware of.

Such a nefarious package could also read browser cookies, SSH keys, emails, photos, and a million of other things.

That depends on the messenger app. Telegram, for instance, supports backing up messages as HTML and/or JSON.

This system seems quite similar to sending messages to oneself on Signal/Telegram/whatever. What I like about using messenger apps is that every note gets a timestamp and that messenger apps are, in my experience, more polished than note-taking apps.

There are screen-locking programs that don't hide what's on the screen (for example `alock` and `xtrlock`). So you can use one of those in a script that also launches this tool.
