The point is that whenever you do "IR -> Instructions" you are opening the possibility for logic errors to become memory errors. E.g. emitting opcode 9 instead of opcode 8 might (on some system) allow an attacker to execute arb

I am slightly confused about why the MutexGuard type is required in the locking example. Why can locking a lock not just return &mut? The API as written does so eventually anyway, through access(). I guess the API as written allows you

Z3 is an SMT solver ( https://en.wikipedia.org/wiki/Satisfiability_modulo_theories ). You can think of it like a SAT solver with extra optimizations for certain domains, so that it doesn't need to do bit-blasting to

Except you still have no way to modify the variable binding on the caller's stack. This is what all of us in the "Java is call-by-value" camp keep yammering on about: changing a value on the heap (an array or object in Java)

But you can't write into the pointer variable itself from inside the callee: static void f(Foo x) { x = ...; } // somewhere Foo y = ...; f(y); The pointer value of y cannot be changed from insi

I wonder, for people coming from non-systems programming languages (e.g. Python), whether it would help to visualize what is actually happening under the hood in a scripting language and comparing that to Rust. As others have noted, this gu

Looks like the LLVM folks are (finally) starting to get serious about making (fast) precise GC possible [1]? Back when I was (struggling at) working on Rust's GC this was by far the biggest hurdle [2]. Good to see they're getting

Interesting, but for looping I think a better point of comparison is iterate: https://common-lisp.net/project/iterate/ In my personal opinion, the iterate loops read better than the code samples of the main page.

The point of the faraday cage is to explicitly allow specific signals by setting up repeaters (i.e. femtocells, or whatever they're called these days) inside the cage.

Yes, I worked on GC as a summer project. Turned out to be way harder than anyone had thought because LLVM isn't really set up to handle high performance GC. I have a talk on it here: https://elliottslaughter.com/2012&#x

I've been incredibly impressed by the willingness of the Rust team to take a step back and re-evaluate old decisions. I think this 1.0 release will be much better for all the iterations put into e.g. dynamically sized types and other t

Diffraction limits are most visible for small apertures (high f-numbers). For surveillance cameras, I would expect* sensor size to be the bigger issue, because as long as sensor size is fixed, signal to noise will be limited by photon noise

And yet, the iPhone basically does this for a number of permissions (location, push notifications, contacts access, etc.), and for the most part it seems to work for even uneducated users of iOS. For most permissions, you might not want thi

I disagree. No security really is as bad as broken security. I'm guessing you think your church website isn't worth securing because it doesn't have any sensitive content. But in a world where surveillance is pervasive, that&

I think we should be a little more amazed that this report is available at all---an through internal channels at that. While we're all bashing the CIA for what they've done (and are right to do so), we should also appreciate that
