Modern processors have powerful vector instructions which allow you to load several values at once, and operate (in one instruction) on all these values. Similarly, they allow you to have vector constants. Thus if you wanted to add some integer (say 10001) to all integers in a large array, you might first load a…

Integrating with other languages and distributing binaries has always raised the WebAssembly's barrier to entry for the average developer, and at Wasmer...
When I wrote the introductory article for libjit , I aimed it at programmers who know what JITs are, at least to some extent. I did mention what a JIT is, but only very briefly. The purpose of this article is to provide a better introductory overview of JITing, with code samples that don't rely on any libraries.
Rust prevents out-of-bounds memory accesses and buffer overruns via runtime bounds checks - what’s the cost of those bounds checks for a real-world, production application?

Deep dive into the new DWARF-based stack unwinder using eBPF.
Is exFAT as fragile as some say?
All kinds of reasonable-sounding beliefs about undefined behavior are wrong. Let's go through them.
Yes, this is a problem of weak static typing of pure C. Pure C is a great tool for some jobs, but here be dragons , as they say.

Mostly to boast of course, but also to help explain to the audience how curl has manged to reach its ten billion installations. This is current incarnation of…
In this blog we'll discuss how we manage Cloudflare IP addresses used to retrieve the data from the Internet, how our egress network design has evolved, how we optimized it for best use of available IP space and introduce our soft-anycast technology
The Great Renaming FAQ
While browsing twitter, I came across this tweet:
Today we are very excited to launch Wasmer 3.0, following three months of work since our first alpha. So, what’s new in Wasmer? - `wasmer` is now able...
An under-appreciated Rust feature
This is Part 1 of a series of posts. Part 2 is available here: Building a baseline JIT for Lua automatically It is well-known that writing a good VM for a dynamic language is never an easy job. High
Porting Linux to Apple Silicon
Poorly behaving web pages and apps are no longer capable of crashing the browser by exhausting memory, thanks to a simple trick.
“Hey, you. Yes you, that function over there. When you’re cleaning up please remember to restore all of my registers. Yes, that one too – what do you think this is, Linux?”That’s the problem I was …
Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. PTP’s predecessor, Network Time Protocol (…
