Windows 9x existed at a very different time. PCI wasn't a given. Plug and play wasn't a given. You couldn't even reliably enumerate all hardware on a system. Hardware detection back then involved a lot of poking at random IO

When a type is 'static, it doesn’t mean it’s leaked for the lifetime of the program. It just means it owns everything it needs and doesn’t borrow anything. It will still free everything it owns when it is freed.

`boost_write` doesn't appear to validate the length of the user supplied buffer before casting and dereferencing either, so that's a kernel-mode OOB read. Not sure how exploitable this actually is though.

This is pretty normal for Rust code that FFIs to external libraries. There's a lot more complexity in writing FFI code - you have to think very carefully about everything you do. Case convention is a triviality here.

Yes. A lot of the work I've done through my career is essentially this, once you boil away the rest of the details.

The problem is that, when you're implementing a foreign trait for a foreign type, you usually want that impl to then be visible to a foreign crate. Not just the local crate. If it were good enough to only have that impl be visible to t

The way to do this in idiomatic Rust is to make a wrapper type that implements drop: struct MyForeignPtr(*mut c_void); impl Drop for MyForeignPtr { fn drop(&mut self) { unsafe { my_free_func(self.0); }

Don't output ANSI colour codes directly - your output could redirect to a file, or perhaps the user simply prefers no colour. Use tput instead, and add a little snippet like this to the top of your script: command -v tput &&g

Asynchronous IO isn't about efficiency. The approach the author takes with their language is just threads, but scheduled in userland. This model allows a decoupling of the performance characteristics of runtime threads from OS threads

Speaking from practical experience, bindgen is a particularly heavyweight dependency. It requires libclang to be available and also adds a considerable amount of time to the compile. If it makes compiling the software easier - and end use

It remains a problem for source packages, which are an important part of Debian necessary for offline and reproducible builds.

by haileys 2y ago
I think this is the same shape of issue that I’ve experienced with Debian for as long as I’ve used it - close to 15 years now. Debian is a great OS, but it targets stability and long term support for its releases. That just isn’t compatible

by haileys 2y ago
Exactly. So you must use Rust's encapsulation features like modules and visibility to ensure that any particular piece of unsafe code _cannot_ receive a pointer that can't be proven to be valid.

There are hard plastic containers, like regular reusable food containers, that have good seals and little vacuum pumps on the lid. You actuate the lid pump a bit and it removes enough air from the container to keep food for a bit longer. It

Yes, a smarter mix of options is the way to go. Cars are a one-size-fits-all approach that can't hope to achieve what we need for a sustainable future. In Perth, Australia, two thirds of all car trips are for distances of less than 5 k

No. EV adoption is an important goal for the car industry's survival. If we're talking about the species' survival, I sure hope we can adopt a broader vision than taking a land-hungry and energy-intensive mode of transport, a
