Many people must have heard this quote (by Phil Karlton) many times: There are only two hard things in Computer Science: cache invalidation and naming things. Two days ago, Nick Tierney mentioned it …
Kernel modules are code components that can be loaded and unloaded by the kernel when required. They are used to extend the functionality…

With git, a cryptographic signature on a commit provides strong integrity guarantees of the entire history of that branch going backwards...
Fixing production issues is one of the key responsibilities of system and network administrators. In fact, I’ve always found it to be one of the most interesting parts of infrastructure engineering. Diving as deep as needed into the problem at hand, not only do you (eventually) have the satisfaction of solving the…

Now that I have your attention. I've been mulling TenFourFox's future for awhile now in light of certain feature needs that are far bigger ...
It's time to put my water cooled Raspberry Pi Cluster to the test. I put it up against my MacBook and a Windows PC to see which performed best
As cheesy as the title sounds, I promise it cannot beat the cheesiness of the technique I’ll be telling you about in this post. The morning I saw Mark …
When benchmarking software, we often start by measuring the time elapsed. If you are benchmarking data bandwidth or latency, it is the right measure. However, if you are benchmarking computational tasks where you avoid disk and network accesses and where you only access a few pages of memory, then the time elapsed is…
When the Compute Module 4 was released (see my CM4 review here), I asked the Pi Foundation engineers when we might be able to boot off NVMe storage, since it was trivially easy to use with the exposed PCIe x1 lane on the CM4 IO Board. The initial response in October 2020 was "we'll see". Luckily, after more people…
JDK 16 is out, and as usual, each new release comes with a bunch of new features, enhancements and bug fixes. ZGC received 46 enhancements and 25 bug fixes. Here I’ll cover a few of the more interesting enhancements.
Explore Plan 9, Bell Labs' innovative operating system. Discover its impact on distributed computing, network-centric design, and modern OS development.
Update : Dongli Zhang reports that newer Linux versions organize the stack differently . The code below will need to be modified accordingly.
When I first got my 133MHz BeBox (not new, sadly), it had "only" 32MB of memory and it had four more SIMM slots to fill. While Be only off...
SQL's UNION operation isn't usually regarded as a way to optimize query performance, but in many cases it can be used to achieve massive improvements in speed.
This post is the last in a three-part series about Cranelift . In the first post , I covered overall context and the instruction-selection problem; in the second post , I took a deep dive into compiler performance via careful algorithmic design.
On this blog, I write about the various computers I use and about the operating systems I use on them. Apart from Windows 7, which is relatively modern, these include Mac OS 10.6 Snow Leopard, which at this point is quite old, and Mac OS 9, which is practically ancient. I’d like to talk a bit about why I use such old…

GitHub has done a lot of work in the last six months to improve performance for large monorepos.
Slack has a global customer base, with millions of simultaneously connected users at peak times. Most of the communication between users involves sending lots of tiny messages to each other. For much of Slack’s history, we’ve used HAProxy as a load balancer for all incoming traffic. Today, we’ll talk about problems we…
C is a simple language. You’re only allowed to have one function with each name. C++, on the other hand, gives you much more flexibility: You can have multiple functions …
