Not the author but I also moved from C# to Rust. In the first place I did not consider Rust for C# works like REST API but after I proficient with Rust I no longer want to work with C# for the following reasons: 1. Microsoft don't want

My observation is most people who suggest Rust alternative don't use Rust. People who actually use Rust known it is worth to rewrite C/C++ software in Rust, either the whole or part by part. There is a tool to convert C source int

The benefit of drivers being in the user-space is it will limit the damage if that driver has vulnerabilities. The downside is, I don't think the performance will be great. The kernel already written in Rust and if all drivers also wri

Rust give more ergonomic to this. In C++ it need a lot of typing for creating a new type compared to Rust.

Checked addition by default will have too much overhead and it will hurt performance, which unacceptable in Rust since it was designed as a system language. Swift can use checked add by default since it was designed for application software

Rust is the only language I can easily control how integer overflow should behave. I can use `var1.wrapping_add(var2)` if I want the result to be wrapped or `var1.checked_add(var2)` if I don't want it to overflow.

I'm coming from C++ now I don't want to use C++ anymore. When C++ was still my primary language I always frustrated with some of its feature like non-destructive move, copy by default and dangling references then I found Rust fixe

For me lack of language specification is not a problem and it is good that Rust only have one implementation so I don't have a headache to support multiple compilers like C++. The only problems I have with trait is lack of const functi

Most C/C++ users don't understand how Rust achieve memory safety because they don't know Rust enough. They always underestimate Rust memory safety. The truth is Rust can give you nearly 100% memory safety. The point of unsafe

I'm living in Thailand for almost 40 years and this is the first time I have a nausea due to earthquake even it is very far from its origin. I can't imagine how much catastrophe the Myanmar has from this earthquake.

To be fair the UB caused by this function come from the underlying C implementation and this function already marked as unsafe on 2024 edition.

Of course the modern C++ are safer but you can still shoot yourself in the foot. Compared to Rust you still need to think about the memory safety when writing C++ while Rust you don't need to think about it at all. The only time you ne

Once you know how Rust works it is likely your Rust code will be faster than C/C++ with less effort. I can say this because I was using C++ for a long time since Visual C++ 6.0 and moved to Rust recently about 3 years ago. One of the r

You are very unlikely to hit this bug in a real world Rust project while C/C++ you can easily hit by a memory safety bug.

Actually the interoperability is very good. C can directly call into Rust and Rust can directly call into C. Rust can construct any C type and can expose opaque pointers to C world.

Actually it is very simple to communicate with the modern hardware (both x86 and ARM). All you need to do is read/write the hardware memory. This called Memory-mapped I/O (or MMIO in short). Of course you cannot do this from the a

Those wiki has some incorrect information. How shadPS4 and fpPS4 works are the same. Almost of them can be categorized as a compatibility layer. The only one that can be called a PS4 emulator is Orbital because it virtualize (and emulate) t

Actually shadPS4 is a compatibility layer. What it does is re-implement the PS4 libraries and translate PS4 shading language into SPIR-V.

It is really depend on the hardware you want to make the emulator. Usually there are 2 kind: 1. Emulate the whole system. 2. Emulate the system API. The first one you write the code to emulate the CPU of target system like OP code interpret
