Note that the author didn't use any QEMU guest-to-host vulnerability here. The agent found a logic bug that facilitated going straight for the hypervisor from inside the guest, but it isn't caused by the use a memory-unsafe langua

QEMU has a secure subset, and the kitchen sink around it. For a properly configured VM, even better if wrapped in SELinux, it is not easy to escape even QEMU. In this case, of the four bugs it found: * Two were in libslirp, which is not par

alice.it is indeed an email provider's domain; based on the code snippet it seems like they are active in other countries. alice.app however isn't registered anywhere.

Windows/386, and later 3.x and 9x, was a virtual machine monitor that could run 16-bit operating systems with 32-bit drivers. The desktop environment you saw was nothing but the main virtual machine, and inside that was the green thr

Even if AI does the coding, I cannot understand the architecture of a change unless you split it in individual tasks that are "as small as possible but no smaller". And even if AI does the code review, the architecture review fall

How do you distinguish engagement maximization and usability maximization?

Not knowing anything detailed about the acts, which terms are you referring to? Notarization?

Or the opposite direction, with repeated "git checkout -p ..." and commit steps. Slightly less comfortable because you have to figure out (such as from "git rebase --edit-todo") the later commit, but it makes testing the

It's not exactly the same problem, in that you can parallelize usage of an LLM and copy it over to another computer, but cannot do the same things with a brain. Put it another way, humans do not have the processing power needed to answ

It's a bit different when "training on any data" means basically storing a lossily-compressed copy of that data, that could be spit out years later if the model decides to do so.

Yes, but the premise here is that for national calls it becomes harder to spoof the caller id. In fact, here in Italy we're seeing an increase in telemarketing calls from Spain and France, so it's not entirely hypothetical.

by bonzini 2mo ago
Reading it in Italian (my native language) is fascinating, as it's a weird mix of mostly modern Italian flexion and Latin sentence construction. It's incredibly taxing, enough so that I stopped after 70-ish stories, but it also ma

I feel the same about Haskell...

by bonzini 2mo ago
Sure but the caller network bills the telemarketer and they could be in cahoots.

by bonzini 2mo ago
International calls pay whatever the caller network wants them to pay. You're assuming that the caller network isn't part of the scam.

0x86 and 0x87 (XCHG rm,r with byte- and word-sized operands) encode nops in the same way as 0x90, but were never redefined as prefixes. It's interesting that a lot of ALU operations occupy four opcodes (memory source/memory destin

z386 is in development right now, and isn't even finished. Do you mean between ao486 and z386?

by bonzini 2mo ago
None was. XCHG AX,AX is special because XCHG AX,reg has a one-byte encoding. You're probably confusing with: - POP CS being broken and later becoming a prefix - some opcodes being "reserved NOPs", i.e. reserved without genera

I am doing something similar to that C-to-Rust rewrite. Except: 1) I'm clearly saying that it's only for my own learning experience and to find ways to improve the original program 2) I am leaving the original license in place and

The problem is that the original formulation was "most people" are unaware of being unskilled, but by now the name is used to mean "some group of people" is unaware of being unskilled. In that sense the article confirms

They write garbage if you turn off your brain. They write code as good as yours if you work together.

Yeah I never use non-interactive rebase. Even if I don't need to edit the todo list, reading it gives me a confirmation of what git will do.

But the real question is 1) whether other human lawyers would catch the error 2) in how much time 3) which of the errors introduced by AI vs. human would have bigger consequences. On 1 and 2 the answers are very likely to be "yes"

First of all I want to say it is not your fault, and also your article is clearly partly human, despite what Pangram says. The thing that I like the least is the headings and the way LLMs always try to put a punchy line. "Correctness t

How does it do that? When the 64-bit pointer is actually a pointer, does it mangle it into something that is certainly not UTF-8 (e.g. changing its top byte to 0xC0, and assuming that bits 56-63 are the same as bits 48-55, or something lik

Is the runtime compiled by the Fil-C compiler, or is it a single huge unsafe block? I honestly don't know the answer.
