Recently I was digging deeper into Raft , an important algorithm in the field of distributed systems. Raft is a consensus algorithm , meaning that it is designed to facilitate a set of computers agreeing on a state of the world (more on exactly how the state of the world is represented later), even when communications…
After spending some weeks playing with Rust, I felt ready to test my skills and try some programming challenges in the [Advent Of Code](https://adventofcode.com/). My approach to tackle some of those challenges was to solve them using Javascript (I use it in my day to day) first and then port the code to Rust. While…
Up to yesterday, my laptop was a large 15-inch MacBook Pro. It contains an Intel Kaby Lake processor (3.8 GHz). I just got a brand-new 13-inch 2020 MacBook Pro with Apple's M1 ARM chip (3.2 GHz). How do they compare? I like precise data points. Recently, I have been busy benchmarking number parsing routines where you…
On the need for low-carbon and sustainable computing and the path towards zero-carbon computing.
The behavior of the Windows scheduler changed significantly in Windows 10 2004 (aka, the April 2020 version of Windows), in a way that will break a few applications, and there appears to have been …
When I got my brand-new MacBook Pro (late 2016), I was interested in testing out the phenomenal SSD performance I had been reading about, r...
Hi everyone, Today we are releasing Windows 10 Insider Preview Build 14316 to Windows Insiders in the Fast ring. At Build 2016 last week, we shared new experiences and new opportunities we’re creating for developers with the Windows 10 Anniversary Update which we will be releasing for free to all Windows 10 customers…
The Pixelbook and four other fairly new Chromebooks have the special flag to enable GPU acceleration, making these the first to get the new feature for Linux. This should bring the Android emulator and improved gaming capabilities to Project Crostini.

I've been moving my home storage over to a UniFi UNAS Pro 8 as part of a larger ...
Some new proposed protocols will encrypt the transport layer headers. Encryption is good, so more encryption must be better, right? Unfortunately there's going to be a huge hidden cost that'll be paid by anyone troubleshooting networking problems.
In .NET 9 we enabled DATAS by default. But .NET 9 is not an LTS release so for many people they will be getting DATAS for the first time…
In this post, I’m going to go through the process of setting up Apple’s A/UX on a Quadra 610. It’s been a long time in the making - I think I had the hardware for nearly a year before I finally got A/UX running properly!
You are also not Spotify, Amazon, Apple, Microsoft, Facebook or one of several other big tech companies I could mention here. If I have excluded anybody reading this - I am sorry.Maybe you will still enjoy the read. For everyone else: This article is probably for you. To give you...
I recently made a setup at work where I had a Nginx server facing the user, which would forward requests to a service running behind an AWS Elastic Load Balancer (aka. ELB). That in itself doesn’t sound like a difficult task, you just find the hostname for the ELB and point Nginx at it with a proxy_pass statement like…
Years ago I worked in the Xbox 360 group at Microsoft. We were thinking about releasing a new console, and we thought it would be nice if that console could run the games of the previous console. E…
Can we make a Rust program that's as small as it's assembler equivalent?
Data-only attacks, those that do not affect a program’s control flow, have long been considered too sophisticated and niche to pose a practical threat. With our research, however, we have built a tool that automatically generates them with surprising ease. We explain how such attacks work, and why our tool, Einstein…

Someone in one of my online communities recently asked about why their Node command was dropping output when piped to another command:
