Many programming languages have standard libraries. What about JavaScript? 🤔️

Deno's goal is to simplify programming, and part of that is to provide the JavaScript community with a carefully audited standard library (that works in Deno and Node) that offers utility functions for data manipulation, web-related logic, and more. We created the Deno Standard Library in 2021, and four years, 151 releases, and over 4k commits later, we're thrilled to finally announce that it's 30 modules are finally stabilized at v1.

This article will investigate how Rust handles dynamic dispatch using trait objects and vtables. We will also explore how the Rust compiler can sometimes optimize tail calls in the context of dynamic dispatch. Finally, we will examine how the vtable facilitates freeing memory when using trait objects wrapped in a Box.

go replan all your STM32H7 projects with RP2350, save money, headaches, and time. As a bonus, you’ll get an extra core to play with too! "But," you might say, "STMicro chips come with internal flash, while RP2350 still requires an external SPI chip to store the flash". Hold on to your hats... there are now RP2350 variants with built-in flash! They are called RP2354A nd RP2354B and they include 2MBytes of flash in-package. The pinouts are the same as the RP2350A/B, for a bonus! Why two pinouts? Because the "more GPIOs" dream also came true! There is now a variant with more GPIOS, available in an 80-pin package. That’s right! It is epic!

What issues or frustrations have you encountered in trying to use and set up Neovim in Windows 11?

I'm currently writing up my experience with installing, setting up, and using Neovim in Windows and would like to hear from others that have tried the same. What was annoying, difficult, or impossible in your experience?

Many devs dream of one day writing their own operating system. Ideally in their favorite language: Rust. For many of us, this dream remains just that: a dream.

Jeremy Soller from System76, however, didn't just contribute kernel code for Pop!_OS, but also started his own operating system, RedoxOS, which is completely written in Rust. One might get the impression that he likes to tinker with low-level code!

In this episode of Rust in Production, Jeremy talks about his journey. From getting hired as a kernel developer at Denver-based company System76 after looking at the job ad for 1 month and finally applying, to being the maintainer of not one but two operating systems, additional system tools, and the Rust-based Cosmic desktop. We'll talk about why it's hard to write correct C code even for exceptional developers like Jeremy and why Rust is so great for refactoring and sharing code across different levels of abstraction.

Neovim is the most admired code editor in the 2024 Stacked Overflow Developer Survey

It's broader than a Neovim specific mapping, I've changed the system keyboard mapping of <Caps Lock> to <Esc> and <F9> to <Caps Lock>.

I think mapping <Caps Lock> to <Esc> isn't uncommon for Neovim users. But I like having <Caps Lock> available for non Neovim purposes.

A stdx (for std eXtended) under the rust-lang organization containing the most-needed packages. ... to make it secure: all packages in stdx can only import packages from std or stdx. No third-party imports. No supply-chain risks.

[stdx packages to include, among others]:

gzip, hex, http, json, net, rand

I find the author's writing style immature, sensationalist, and tiresome, but they raise a number of what appear to be solid points, some of which are highlighted above.

This blog post is the result of my attempt to implement high-performance matrix multiplication on CPU while keeping the code simple, portable and scalable. The implementation follows the BLIS design, works for arbitrary matrix sizes, and, when fine-tuned for an AMD Ryzen 7700 (8 cores), outperforms NumPy (=OpenBLAS), achieving over 1 TFLOPS of peak performance across a wide range of matrix sizes.

By efficiently parallelizing the code with just 3 lines of OpenMP directives, it’s both scalable and easy to understand. The implementation hasn’t been tested on other CPUs, so I would appreciate feedback on its performance on your hardware. Although the code is portable and targets Intel Core and AMD Zen CPUs with FMA3 and AVX instructions (i.e., all modern Intel Core and AMD Zen CPUs), please don’t expect peak performance without fine-tuning the hyperparameters, such as the number of threads, kernel, and block sizes, unless you are running it on a Ryzen 7700(X). Additionally, on some Intel CPUs, the OpenBLAS implementation might be notably faster due to AVX-512 instructions, which were intentionally omitted here to support a broader range of processors. Throughout this tutorial, we’ll implement matrix multiplication from scratch, learning how to optimize and parallelize C code using matrix multiplication as an example.
