Ever since the iPhone 5S was announced a couple of weeks ago , the world of tech journalism has been filled with massive quantities of misinformation . Unfortunately, good information takes time, and the world of tech journalism is more about speed than accuracy. Today, as suggested by a variety of readers, I'm going…

After nearly 6 years since R1/alpha4, Haiku R1/beta1 has been released. See “Release Notes” for the (lengthy) release notes, “Press contact”, for press inquiries … and “Get Haiku!” to skip all that and just …

Typically, if you're designing a storage system - such as a filesystem, or a database - one of your major concerns is how to store the data on disk. You have to take care of allocating space for the objects to be stored, as well as storing the indexing data; you have to worry about what happens when you want to extend…
Preface In October 2023 I learned about HTTP/2 Rapid Reset attack, dubbed “the largest DDoS attack to date”. I didn’t have deep knowledge of HTTP/2 back then. I knew its basics like frames or HPACK but I was focusing more on HTTP/1.1 protocol and programming languages vulnerabilities. I decided to dedicate time to…
Exploring how to measure code sloppiness, why correct code can still erode a codebase, and why human intuition and taste still matter.
Don't you love misleading documentation?

In V8 v9.1 we’re improving V8 performance by 5–15% with Sparkplug: a new, non-optimizing JavaScript compiler.
Welcome to the first feature article on our site. We’re going to cover an ongoing problem with x86 emulation that affects every application that we emulate. This comes down to a single over-arching term that has wide-reaching ramifications; Emulating the x86 Total Store Ordering memory model (x86-TSO) .
A few weeks ago I was looking at some of the performance metrics for my site. Specifically, I wanted to see how I was doing on our newest metric, first input delay (FID). My site is just a blog (and doesn’t run much JavaScript), so I expected to see pretty good results.
I had summarized/discussed a couple papers ( Haystack , Memcache caching ) about Facebook's architecture before. Facebook uses simple arch...
The Beav in all his geometric glory. Even though I have been using some Linux distribution or another pretty much daily for roughly two decades, I...
Ever since the Pi 2 model B went to a 4-core processor, disk IO has often been the primary bottleneck for my Pi projects. You can use microSD cards, which aren't horrible, but... well, nevermind, they're pretty bad as a primary disk. Or you can plug in a USB 3.0 SSD and get decent speed, but you end up with a cabling…
What I learned mining 125,000 vulnerabilities from Linux git history. The average kernel bug lives 2.1 years before discovery, but some subsystems are far worse.
This guide describes how to tune your AMD64/x86_64 hardware and Linux system for running real-time or low latency workloads.
When you can’t remove an app which you installed just a few minutes ago, you know there’s something wrong. Here’s the solution, and why this is bad security.
We are archiving Atom and all projects under the Atom organization for an official sunset on December 15, 2022.
Tracing one vector-add kernel from nvcc all the way down to the warps that execute it.
Porting Linux to Apple Silicon
Tape storage is surprisingly not dead! If you are here then you may be considering using LTO tape as part of your backup or your long term archiving strategy. I’m here to mostly talk you out of it, or at best make sure that you are aware of what you are walking into.
We are thrilled to announce the Windows Package Manager preview! If you’re already familiar with what a package manager is, feel free to skip this
Why a filter is slowest when it keeps half of random input, and what a branchless rewrite gains there and loses at 1%.
Previously, on Jepsen, we saw Chronos fail to run jobs after a network partition . In this post, we’ll see MariaDB Galera Cluster allow transactions to read partially committed state.
