For over 10 years now, I run two self-built NAS (Network Storage) devices which serve media (currently via Jellyfin) and run daily backups of all my PCs and servers. In this article, I describe my goals, which hardware I picked for my new build (and why) and how I set it up.
This article is an excerpt of my new book Cloudflare for Speed and Security where you will learn, among other things, how networking works in order to create fast, secure and scalable applications. If you are not overspending on compute (like many companies do because of "scale") then your biggest
The pressure the cloud puts on margins can start to outweigh the benefits you scale and growth slows. Understand how much market cap is being suppressed by the cloud to help inform the decision-making framework on managing infrastructure as companies scale.

I gave in to my impulses and bought myself a small single board computer to be my power-efficient home server, here's how it went.
I will demonstrate FPGA-based 64-bit RISC-V computer, capable of booting and running the riscv64 port of Fedora. Using Free/Libre packages available as part of the Fedora repositories, this machine is capable of recompiling not only its own software (e.g., kernel, glibc, gcc), but also its own gateware (i.e., FPGA…

According to the Global Commission on the Economics of Water: "We are seeing the consequences not of freak events, nor of population growth
Docker Compose is a brilliant tool for bringing up local development environments for web projects. But working with multiple projects can be a pain due to clashes. For example, all projects want to listen to port 80 (or perhaps one of the super common higher ones like 8000 etc.). This forces developers to only bring…
Have you ever wondered what lies beneath the surface of an npm package? At its heart, it’s nothing more than a gzipped tarball. Working in software development, source code and binary artifacts are nearly always shipped as .tar.gz or .tgz files. And gzip compression is supported by every HTTP server and web browser…
Starting from the constraint that only sudo logrotate * may be run, and ending at root: abusing the log file flag to overwrite root owned scripts and ride cron to privilege escalation.
