The Microsoft Azure Core Upstream team is excited to announce the Hyperlight project, an open-source Rust library you can use to create very small VMs for embedded functions. Learn more.
macOS comes with a lot of built-in utilities. Here's a list of some that I find interesting.
Almost nobody understands how traceroute works. Worse, it's not a real tool
Explore 3 limitations of using frame pointers for stack unwinding and profiling in Linux that are often overlooked, plus possible future alternatives.
I don’t want to post yet another anti-systemd rant, but I think the ubiquity of systemd could eventually create real problems for embedded Linux. I just wish I knew what to do about it.
Google networking leaders reflect on the milestones that led to Jupiter supporting 13 petabits per second bandwidth, and what comes next.
In this post we look at the impact of a new feature of Ruby 3.4 on Shopify’s monolith.

Given that events play such a central role in event-driven architecture, there’s an astonishing lack of agreement on what should be contained in an event. This may be rooted in the fact that, depending on your perspective, events fulfill different purposes.
OpenZFS 2.3.0 will be released any day now, and it includes the new “Fast Dedup” feature. My team at Klara spent many months in 2023 and 2024 working on it, and we reckon it’s pretty good, a huge step up from the old dedup as well as being a solid base for further improvements. I’ve been watching various forums and…
The demo shows that even though the behavior appears similar, TCP connections leak when using the io_uring driver but not with the epoll driver. I've also tested this across various io_uring runtimes, and it turns out to be a common issue across all of them.
It has been eighteen years of libcurl ABI stability.
We are thrilled to announce the release of **Wasmer 5.0**, the latest milestone in our journey to make WebAssembly the greatest tool for executing softw...
One of the quickest ways to determine whether particular application runs using Xwayland is to resize one of its windows and see how it behaves, for example
Okay, sorry for the clickbait. NixOS is not reproducible according to the Reproducible Builds definition. I keep reading people making this claim repeatedly on orange-site, even LWN.net made a similar claim when writing about Nix and Guix earlier this week.1 Along with their recently launched wiki. So, what is the…
If you love exploit mitigations, you may have heard of a new system call named mseal landing into the Linux kernel’s 6.10 release, providing a protection called “memory sealing.” Beyond notes from the authors, very little information about this mitigation exists. In this blog post, we’ll explain what this syscall is…
As our first quantized models in this Llama category, these instruction-tuned models retain the quality and safety of the original 1B and 3B models, while achieving 2-4x speedup.
A while back I had to deal with a bit-packed format that contained a list of integer values encoded in one of a pre-defined sets of bit widths, where both the allowed bit widths and the signed-ness…
RISC-V is currently quite slow compared to modern CPUs in 2024.
Thoughts on how compiler and database optimizers should evolve in the future, focusing on predictability and guarantees instead of smarts and heroics
Why are streaming joins so tricky? Discover the hidden complexities of real-time data, and learn how to tame the infinite stream!
ISRG has been investing heavily in the Rustls TLS library over the past few years. Our goal is to create a library that is both memory safe and a leader in performance. Back in January of this year we published a post about the start of our performance journey. We've come a long way since then and we're excited to…
I commented on Lobsters that /tmp is usually a bad idea , which caused some surprise. I suppose /tmp security bugs were common in the 1990s when I was learning Unix, but they are pretty rare now so I can see why less grizzled hackers might not be familiar with the problems.
As much as Andy loves PostgreSQL, there is one part that is terrible and causes many headaches for people. Learn what it is and why it sucks.
Asynchronous code does not require the rest of your code to be asynchronous. I can’t say the same for blocking code.
Understand .NET 9.0 LINQ performance improvements, faster iterator and the usage of Span
Many companies are running old Postgres versions and missing out on many improvements. The reasons: Postgres works and upgrades suck.
In September, machine learning engineers at Mozilla filed a bug report indicating that Firefox was consuming excessive memory and CPU resources while running Microsoft’s ONNX Runtime (a machine learning library) compiled to WebAssembly.
