@erwanaliasr1 @KernelRecipes Woah, this is an absolutely stunning picture! I'll definitely watch her talk later 😁🥳

@blitzclone You can be always use NNTP to get the original mail to reply to. Another blast from the past!

auth bypass confirmed!

> INFO:paramiko.transport:Authentication (password) successful!

mm_keyallowed_backdoor cmd 1 allows to override the response for mm_answer_authpassword with a custom one. if you set it to { u32(9), u8(13), u32(1), u32(0) } you can login with any pass 🤓

@blitzclone @fagiolinux You only hate the ones that want to run RHEL on Atom
- which means <0.01% of the RHEL customer base most likely.

[Alexander Graf - @[email protected] @_AlexGraf]

@never_released @fagiolinux @blitzclone You mean like emulating an FPU? 😂

Alas, BMI doesn't need new register files.

[Alexander Graf - @[email protected] @_AlexGraf]

@fagiolinux @blitzclone Make the low end slower (but keep it functional) to accelerate high end machines. Not the worst trade off 😁

[Alexander Graf - @[email protected] @_AlexGraf]

@fagiolinux @blitzclone You could just trap-and-emulate for those in kernel, like in good old times 😎

@never_released My favorite part was that no single dive happened in a pool - always in the sea, even the very first lesson. We stayed at Chalok baan back then.

[Alexander Graf - @[email protected] @_AlexGraf]

@never_released You could learn to dive. Koh Tao is great for that - and full of fun people to enjoy life with (at least what I remember from 10 years ago). Best to take a buddy with you :)

@hugelgupf Probably better if you Fax it instead? 😁

@awakecoding @timmisiak Load the dll in Ghidra, import its pdb from the MS server, then correlate the decompiled code with your sources :).

[Alexander Graf - @[email protected] @_AlexGraf]

@blitzclone Will you be at LPC to talk about it?

[Alexander Graf - @[email protected] @_AlexGraf]

@blitzclone We'll talk about it and some more controversial implementation details at LPC too

[Alexander Graf - @[email protected] @_AlexGraf]

@blitzclone Yes, we have a working UP prototype that handles 90% of VSM in QEMU, but it's not pretty enough to post yet. Are you interested to help? :)

@bert_hu_bert @nomad421 @jgschraiber How well does packed nucleotide data compress? I would think not badly? In that case, you could search directly on the compressed data hunks (incl edges) to save on memory bandwidth, no?

[Alexander Graf - @[email protected] @_AlexGraf]

@mikeyneuling Back at IBM? That was quick

[Alexander Graf - @[email protected] @_AlexGraf]

@never_released @itanium_guy Not that anyone (economically) cares 😁. What are the odds that you have a business critical, binary only (no more source) IA64 Windows application? 😎

[Alexander Graf - @[email protected] @_AlexGraf]

@never_released @itanium_guy I don't see why anyone would care 😅. If you want a slowly emulated HP system, you just use ski. Qemu-user would have allowed to run binary only legacy code decently fast on modern systems.

[Alexander Graf - @[email protected] @_AlexGraf]

@never_released @itanium_guy Sounds about right. There seems to be renewed interest even? https://t.co/MJh9xg3S5u
