Last week, I reached an exciting milestone in my career as a programmer. For the first time in my life, I ran code directly on hardware , with no Operating System sitting between the bare metal and my code.
How does SQLite work? Part 1: pages!
As a software developer, I spend a lot of time using the terminal, or more properly, a “terminal emulator”. Tools like iTerm2 , or PuTTY , or GNOME Terminal , or the classic xterm and rxvt are all “terminal emulators”; they take raw text and formatting instructions and interpret them to display pretty text on the…
JSON is important, damn near everything that we do as programmers or operators involves JSON at some point. JSON decoding is expensive, if your product talks JSON then performance of marshalling data in and out of JSON is important. This is a talk about designing an efficient replacement for encoding/json.Decoder .
In the last post of this series , I set up NeXTstep on an HP PA-RISC workstation . Today, I’m going to get down to business: configure networking, install system patches, outfit it with developer tools, and install some useful software!
With Apple’s recent announcement that they are moving away from Intel X86 CPU’s to their own ARM CPU’s for future laptops and desktops I thought it would be a good time to take a look at the some differences that can affect systems programmers working in Rust.
My macOS Big Sur Patcher allowed countless users of older Macs to enjoy the new design and features of macOS Big Sur.
It's late 2020 and you just got a brand-new Mac with Apple's own ARM processors. Exciting! But what will development be like?
Back with a post after 6 years of silence. If you had to parse a microsecond-resolution epoch timestamp as quickly as possible, how would you do it? We’ll take a look at using compiler intrinsics to do it in log(n) time.
Today we are excited to announce general availability of Microsoft Defender Advanced Threat Protection (ATP) for Linux! - This initial release delivers...
Redis is a fast single-threaded data structure server, commonly used as a cache, scratchpad, queue, or coordination mechanism between distributed applications. It offers operations over a broad array of datatypes , including binary blobs, lists, sets, sorted sets, maps, geohashes, counters, channels, streams, and…
Whenever I have a chance, I extol the virtues of message-passing and event-loops in structuring concurrent workflows in Rust. However, in…
We announce the technology preview of NGINX support for QUIC+HTTP/3 as pre-release software, available for interoperability testing, feedback, and code contributions. HTTP/3 replaces TCP with QUIC, which is designed to support multiplexed connections more reliably.

In November 2018 AWS published an Open Source tool called Firecracker , mostly a virtual machine monitor relying on KVM , a small sized Linux kernel, and a stripped down version of Qemu . What baffled me was the speed at which the virtual machine would fire up and run the service. The whole process is to be compared…
In response to popular demand, Microsoft announced a new feature of the Windows Subsystem for Linux 2 (WSL 2)—GPU acceleration—at the Build conference in May 2020. This feature opens the gate for many…
My program received a SIGSEGV signal and crashed with "Segmentation Fault" message. Where does the "V" come from? Did I read it wrong? Was there a "Segmentation *V*ault?"? Or did Linux authors make a mistake? Shouldn't the signal be named SIGSEGF?
They are popular and they are misunderstood. Containers have become the default way applications are packaged and run on servers, initially popularized by Docker. Now, Docker itself is misunderstoo…
July 1, 2020: Post updated to take care that Amazon EFS increased file system minimum throughput, when burst credits are exhausted, to 1 MiB/s. I am very happy to announce that AWS Lambda functions can now mount an Amazon Elastic File System (Amazon EFS), a scalable and elastic NFS file system storing data within and…
