I recently hit some multi-minute delays on my workstation. After investigating I found that the problem was due to a lock being held for five minutes, and during that time the lock-holder was mostl…
I seem to have a habit of writing about super powerful machines whose many cores are laid low by misuse of locks. So. Yeah. It’s that again. But this one seems particularly impressive. I mean, how …
The V8 Lite project dramatically reduced the memory overhead of V8 on typical websites, this is how we did it.
Essay on the benefits of speedy software, and how it affects user perception of engineering quality and overall usability
Reports that some AVID Users Macs would no longer boot. It now may be that a Google Chrome Keystone update modifies /var on NON SIP Protected Macs.
We’re pleased to announce that Microsoft is supporting the addition of Microsoft’s exFAT technology to the Linux kernel.

Introducing DTrace on Windows 10
Nearly a decade ago I wrote about the Quantum Compute Cloud on April Fool’s Day. The future has arrived and you now have the opportunity to write quantum algorithms and to run them on actual quantum computers. Here’s what we are announcing today: Amazon Braket – A fully managed service that allows scientists…

WebAssembly is an assembly language for a conceptual machine, not a physical one. This is why it can be run across a variety of different machine architectures. WebAssembly needs a ...

I think it is safe to state that hash tables (e.g. maps in Go, dicts in Python, HashMap in Java, etc.) are far more common than ordered data structures such as trees for in-memory data structures. One data point is that in a talk about C++ hash table optimization at Google ( available in Abseil ), the speaker noted…
These are my stupid unix tricks. I hope that they are useful to you. Platform Note I use Mac OS X (pron: “ten”). If you don’t, you might want to switch…

tl;dr I found a vulnerability in apt that allows a network man-in-the-middle (or a malicious package mirror) to execute arbitrary code as root on a machine i...
In this tutorial, we will implement a Rust program that attempts to utilize 100% of the theoretical capacity of three relatively modern, mid-range CPUs. We'll use an existing, highly efficient C++ implementation as a reference point to compare how our Rust program is doing. We start with a simple baseline solution of…
Lin Clark introduces the Bytecode Alliance, and uses Code Cartoon illustrations to share their vision of a WebAssembly ecosystem that is secure by default, fixing cracks in today’s software foundations. ...

After languishing through the CPU dark-ages (read: Intel trying real hard to keep people on 4 cores so they could charge an arm and a leg for more), the last two years has seen a vertible tsunami of advances in CPU technologies. AMD's introduction of an 8-core CPU (the 1700X) began the rat-race and with both AMD and…
Last year I got certified as an EMT. As part of the training I shadowed an ambulance for a day and assisted with each run. For each patient we treated, we had to fill out a patient care report. A patient care report. (source) EMTs are just one part in a long chain. If they transport a patient to a hospital, the…

A common question I get at work is “how do I learn to build big distributed systems?”. I’ve written replies to that many times. Here’s my latest attempt.
Today, we're thrilled to announce the open sourcing of Lucet, our native WebAssembly compiler and runtime. WebAssembly is a technology created to enable web browsers to safely execute programs at near-native speeds, and it's been shipping in the four major browsers since early 2017.
