I know we are supposed to be worried about the world supply of fresh water. I have been hearing that at least for the last 40 years, and the statistics are alarming. 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.
Earlier this year, I attended CfgMgmtCamp in Ghent and listened to Adam Jacob’s “What if Infrastructure as Code never existed” keynote. Note: I’d like to extend a huge thanks to
Sure, docker-compose is great, but could we get similar functionality using just the tools that are built into CoreOS? Can we get automatic updates, too? Yes we can! 📦
Let me introduce you to μMon, mypersonal, minimalist, opinionated take on host monitoring based onRRDtool, SNMP, some lightweightshell scripting, and a small...
I love GitHub Actions: I’ve been a daily user of it since 2019 for both professional and hobbyist projects, and have found it invaluable to both my overall productivity and peace of mind. I’m just old enough to have used Travis CI et al. professionally before moving to GitHub Actions, and I do not look back with joy 1…
AWS will charge for IPv4 addresses but its IPv6 support lacks severely

RabbitMQ and Apache Kafka might appear similar but serve very different needs. Read to learn and make an informed decision suitable for your needs.
It is no secret that I am not a fan of logs; I’ve baited (rapala in work lingo. Rapala is a Finnish brand of fishing lure, and used to mean baiting in this context) discussion in our work chat with things like: If you’re writing log statements, you’re doing it wrong. This is a pretty incendiary statement, and while…
In this article, you will learn what stands behind the label immutable when it comes to Linux systems
AWS grew its IPv4 estate with an additional 27 million IP addresses to now owning 128 Million IPv4 addresses. At a value of $35 per IPv4 address, the total value of AWS’ IPv4 estate is ~4.5 Billion dollars. An increase of $2 billion
<p>A webhooks allow two applications to communicate events. It is relatively simple to get started using webhooks using HTTP and JSON. However, there a number of failure scenarios that developers should be aware of in order to make their webhook implementation robust.</p>
The software industry is learning once again that complexity kills
Some notes about the UK air traffic control meltdown
In the first 45-minutes the market was open the faulty software deployment sent millions of child orders into the market resulting in 4 million transactions against 154 stocks for more than 397 mil…
I’ve been running a Kubernetes cluster on a mix of virtual and bare metal machines with Hetzner for about a year now, and while the setup has served me well, being a very exploratory exercise at the time it wasn’t very well documented.
Updated 2024-09-17 to reflect updated PgBouncer support for protocol-level prepared statements 🐘 To start, I want to say that I’m appreciative that PgBouncer exists and the work its open source maintainers put into it. I also love working with PostgreSQL, and I’m thankful for the incredible amount of work and…
First part of a story on how I’ve built 25 Gbps router for home use.
There's a "hidden" API on HIBP. Well, it's not "hidden" insofar as it's easily discoverable if you watch the network traffic from the client, but it's not meant to be called directly, rather only via the web app. It's called "unified search" and it looks
You bump into DORA in the wild a lot.
It is time to celebrate EC2-Classic, which defined early cloud computing, and which is finally retiring.
Docker is not just a way of running programs on Linux without a virtual machine. Docker is 4 things.
4 Years In, OpenTelemetry Delivers on its Promise for Open Observability
A retrospective on a NetBSD server set up in 2010 under tight deadlines, running almost untouched for over a decade on consumer-grade hardware-proof of the OS's remarkable stability.
