Dunking Thoughts: Perfection and Time

I've suffered from perfectionism throughout my life. It's been mostly negative. I've learned to embrace imperfections. Setting perfection as a theoretical bound and not more, could be a good thing but should be aware of many of its sharp edges. With infinite time everything will be perfect Everyone is capable of producing perfection if given … Continue reading Dunking Thoughts: Perfection and Time

Announcement 📢 Releasing dlpackrs

DLPack is the standard in-memory data format that facilitates zero-cost tensor transfer across major Deep Learning frameworks (PyTorch, TensorFlow and TVM) and the supported Python Array processing frameworks such as Numpy, CuPy. The dlpackrs provides a safe idiomatic Rust binding where Rust ndarray and tensor frameworks can use it to gain the same kind of … Continue reading Announcement 📢 Releasing dlpackrs

Announcement 📢 Releasing smartalloc

If you happen to write unsafe code in Rust where normal static checks are not available and want better UX for detecting memory issues along side using various sanitizers, checkout my new crate smartalloc which provides idiomatic Rust binding for the original C version here. Beside the reason in README, note that MIRI can't be … Continue reading Announcement 📢 Releasing smartalloc

Announcement 📢 Create your own programming language with Rust

After almost a year from my last blog post, in this short post I'm very happy to announce that I'm writing a free online book where early chapters are available now. I've explained my motivations and goals in the introduction. The accompanying codes are also available on my GitHub. Feedbacks are welcome and happy learning. … Continue reading Announcement 📢 Create your own programming language with Rust

Rust std study series: Interior mutability

Continuing the standard library study, it's time for Cell<T>! Rust compiler enforces multiple reads access and a single write access mutually exclusive, i.e. either multiple shared references & or one and only one mutable reference & mut. So essentially, Rust prevents the evil of aliasing and mutation between multiple threads. Cell<T> is a sharable mutable … Continue reading Rust std study series: Interior mutability

Rust std study series: LinkedList

Continuing from Rust standard library study series, it's time for LinkedList<T>. Note that implementation are taken from Rust stable v1.33.0. A doubly-linked list with owned nodes. The LinkedList allows pushing and popping elements at either end in constant time. Almost always it is better to use Vec or VecDeque instead of LinkedList. In general, array-based … Continue reading Rust std study series: LinkedList

Variance in Rust: An intuitive explanation

Recently I've made a presentation about subtyping and variance in Rust for our local Vancouver Rust meetup, but I still think intuition was rather lost in the formalism, so here's my shot at explaining it as intuitively as I can. For more succinct definitions, please checkout the presentation or the resources at the end. First, … Continue reading Variance in Rust: An intuitive explanation
