I expect that UD2 stops instruction fetching (beyond the current block) and conversion to µops. A software interrupt or supervisor call should probably do neither because most of the time, these instructions eventually return and continue e

The leakage wouldn't be from training, but from other uses of Personal Data. As far as I understand it, users can opt out from the training aspect, but they cannot stop their conversations (“User Content”) being used “[t]o improve and

If it actually exists, the protection would like go into the other direction: prevent playback of arbitrary MIDI files on the digital piano, instead of protecting the MIDI data against playback on other devices.

As far as I understand it, the other efforts have not reported most of their findings to upstream developers, focusing on critical findings only. This is understandable because upstream interactions at scale are difficult.

It's still beneficial on some x86-64 implementations to rewrite indirect jumps (as used in PLT stubs) to direct jumps when feasible. For example, AMD says this about the Zen 4 architecture: > Only a limited number of indirect target

Why do you think these volunteers supported the attack? I don't think there's a published statement to the effect. Even the U.S. government does not claim that (at least not in its written communication). The perpetrators very lik

The TUI version of Claude Code just isn't very good, though. The default keybindings do not work in the majority of terminals (because they generate the same byte sequences for key sequences assigned to different commands). Editing lar

These builtins of course exist, it's how compilers keep track of the behavior of these functions. For GCC, there is -minline-all-stringops: https://gcc.gnu.org/onlinedocs/gcc-16.2.0/gcc/x86-Options.ht...

Are you sure this is actually makes a difference in your build? Mine doesn't have the SB-INTERPRETER package, so I doubt binding the variable has an effect.

Compiling to bytecode is still compilation. An interpreter would operate directly on the S-expressions. Obviously, this makes some constructs (such as TAGBODY) very inefficient.

Isn't at least one of them undefined? `(1 ,@2) It's always surprising to me how many things Scheme leaves undefined. Other examples are evaluation order (in some rather surprising places) or the value of: (make-bytevector 4)

I wonder what the intent is behind releasing the weights under a CC-BY-NC license. Is it about restricting any commercial use of the weights, including for inference?

Not in typical builds of SBCL: all code is compiled before evaluation.

I think we'd need something different to make that a reality today. It's likely that decentralized compute eventually wins out here as well. It usually does. But without architectural changes, it will take a couple of years before

Centralized inference can easily increase batch size, leading to huge efficiency gains in the usual scenario where most users have just one or very few session. Using local resources efficiently requires some way to increase the batch size.

It's not really about a monorepo, but how many changes you can have in flight in parallel. Desirability of merge-and-rebase-and-check depends on more factors: the rate of change, the number of developers, the time the pre-merge checks

We have plenty of functions that convert one byte array to another byte array. Both arrays have specified bounds. The functions are total (an error return indicates if the input or output arrays are incomplete). Most of them do not even hav
