I'm writing a linker. It's an unusual linker. It's focus is not on producing executable files. Instead, its focus is to facilitate rapid iteration on a program without having to re-link or re-open it after making changes. It is hot-loading of code at an object-file granularity.
When I worked at Google, fleet-wide profiling revealed that 25-35% of all CPU time was spent just moving bytes around: memcpy, strcmp, copying between user and kernel buffers in network and disk I/…
An article by Anonymous : In 2017, Target announced that we had prioritized stores at the center of how we serve our guests – no matter how they choose to shop. To make this store-as-hubs model work, we spent several years redesigning operations and modernizing how we conduct business. We invested billions of dollars…

Event-driven systems come in all sorts of shapes and sizes. The obvious commonality is; they all use events to communicate information. These events come in many shapes and sizes, and determining what goes into an event has an immense impact on the design of your system.

In April of this year, FreeBSD patched a 13-year-old heap overflow in the Wi-Fi stack that could allow network-adjacent attackers to execute arbitrary code on affected installations of FreeBSD Kernel. This bug was originally reported to the ZDI program by a researcher known as m00nbsd and patched in
Sometimes you need info about hardware, and you probably lost your invoice, spec list or a password to a store website. Maybe you did an upgrade and this info isn't accurate anymore. It's an easy case for home users, but what to do is you have many machines

Easily migrate from Linux to FreeBSD. Explore key differences, insights, and useful tricks to adapt seamlessly between the two systems.
Amazon Elastic File System (Amazon EFS) was announced in early 2015 and became generally available in 2016. We launched EFS in order to make it easier for you to build applications that need shared access to file data. EFS is (and always has been) simple and serverless: you simply create a file system, attach it […]
Simply changing the order of some uint variables we managed to drop our memory usage significantly
A deep dive into the futex system call and how it is used to process synchronization functions.
In December 2021, we discovered a new multi-platform backdoor that targets Windows, Mac, and Linux that we have named SysJoker.
Data management decisions don’t have to be costly. Introducing Tiered Storage, a low-cost infinite storage tier for your historical data needs.
A map can always grow in memory; it never shrinks. Hence, if it leads to some memory issues, you can try different options.

I saw an opportunity to fix self-hosted runners for GitHub Actions. Actuated is now in pilot and aims to solve most if not all of the friction.
Multiple installation media are provided for PC, Raspberry Pi, and MNT Reform. For PC, burn an .iso file to CD, or dd it directly to USB media. For Raspberry Pi or MNT Reform, dd an .img file directly to sdcard.
As I mentioned in my last post, I spent a good chunk of my spare time over the past 6 months working on a project I’ve been thinking about for over a decade. I bought a Chumby 8 in 2011. It’s an 8″ touchscreen device powered by the Marvell PXA166 processor. It is essentially a souped-up digital picture frame with…

Starting from v8.0.27, the MySQL daemon shows its thread names at the OS level too, for better troubleshooting. The MySQL 8.0.27 release notes say this: To assist monitoring and troubleshooting, the Performance Schema instrumentation is now used to export names of instrumented threads to the operating system. This…
TLDR: Neon separates storage and compute, substituting the PostgreSQL persistency layer with a custom-made distributed storage written in Rust. Due to this separation, some nodes don’t have persistent disks. The original Raft paper works only with uniform nodes, but Paxos variants support proposers without storage and…
