My work on LLDB’s FreeBSDKernel plugin:
https://minsoo.io/future-of-the-freebsd-kernel-lldb-plugin/The name FreeBSDKernel will be changed to FreeBSD-core, since it only provides functionalities to examine core dumps. Traditional live kernel debugging is done through gdb-remote plugin with FreeBSD’s gdb stub.

FreeBSD has a patch that converts minidump to ELF core dump: https://reviews.freebsd.org/D19253
Instead of reimplenting kvm in C++ for LLDB, how about converting minidump to ELF core dump during savecore(8) and debugging the dump with FreeBSDKernel plugin which inherits classes from ProcessElfCore/ThreadElfCore?
This also opens door for cross-platform kernel dump debugging on GDB.

@minsoochoo Given that LLDB has a minidump plugin, can’t we just load them directly? Is there anything missing from the minidump that would need to be added to the ELF core?

Nuova installazione artistica del collettivo di artisti anonimi Secret Handshake
L'installazione, intitolata "King of the World", ritrae i due personaggi nella ricostruzione di una scena iconica del film Titanic con i personaggi Jack e Rose
Le targhe poste accanto alla scultura fanno riferimento ad accuse di legami tra Trump ed Epstein
Se pensate che riguardi solo loro, vi sbagliate: il nostro governo è parte dell'orchestra che suona sul ponte della nave

@andre123 mi ero inventato il discutibile neologismo "facenda" sul calco del latino agenda; se però lo legge qualche accademico della crusca rischia un colpo apoplettico @itanglese @italofonia
Io ardirei usarlo, facenda, al grido di "anche noi possiam coniare neologismi!"

Profuse apologies for not hiding my post on AI resistance behind a content warning, sigh. It's a really divisive topic and I hope I didn't offend anyone (especially devs who have no choice).
Anyway I'm off to pick up my little one from daycare so I will be mostly offline for the rest of the day.
Wishing you all a great morning / afternoon / evening wherever you are 🌞

@_elena @WeirdWriter wrote two great Anti LLM posts, from the point of view as a writer and what it's doing to his community, if you want something that's outside commentary on this. Have tissues, you will cry from the beauty and care after getting angry.

Omar Sosa & Seckou Keita – Transparent Water (2017)
Sin dalle prime note la musica trasporta istantaneamente gli ascoltatori in un viaggio all'interno del proprio spirito e allo stesso tempo in un viaggio nel mondo reale. Un'esplorazione della musica afro-cubana in tutte le sue forme, una intensa meditazione sui cicli della vita e dell'esistenza... https://noblogo.org/available/omar-sosa-e-seckou-keita-transparent-water-2017

@jwildeboer Not sure why, but I just had scenes from "Dead Poets Society" flash in my head when reading this.
