I once worked for a company where they managed to create about half a million subversion commits in just 2 or 3 years, with about 3 developers working on it. I’ll leave it as an exercise to guess how they managed to do that :-)

If you’re a graduate interviewing for a software job and wondering what a typical day is like, here’s some notes from what I did last Tuesday. It was a pretty typical day.

There are various similar guides on other sites, but many of these guides were partially incomplete, so I’ve tried to write the most complete guide as possible, which can be used by paranoid users like me.

Brave is a chromium based browser, which comes with a built-in adblocker and with a “rewards” program, that is supposed to make you earn money. But the relevant part today is that Brave is advertised as a “private browser by default”.

Alle sitzen vor der Glotze, irgendwo vor einer Bar. Warten auf Tore bei der Fußball-Europameisterschaft. Und dann geht der Fernseher aus. Das ist fies. Und lustig. Vielleicht war unser Netzbastler Moritz Metz in der Nähe.

This blog post is about an experiment to automate creation of Kubernetes Network Policies based on actual network traffic captured from applications running on a Kubernetes cluster.

In the afternoon of October 17, 2013 we merged the first config file ever that would use Travis CI for the curl project using the nifty integration at GitHub.

The registrar and the registry must communicate with one another. The registrar asks the registry whether the name tested by the user is free and available for registration. The registrar then asks the registry to place the name in the database. This communication follows a standardised protocol called EPP, Extensible Provisioning Protocol.

A number of years ago we started the Discoverable Partitions Specification which defines GPT partition type UUIDs and partition flags for the various partitions Linux systems typically deal with.

Remember that I didn't force you to take the software. The act of taking the software was done under free agency, so getting mad about the free gift of some open source code that you chose to take seems to be more your own problem than mine; you are totally capable of using that free agency again and stop using the source code.

Ubiquiti make some of the best bang-for-the-buck networking equipment. They market their UniFi ecosystem at small businesses, but they can make great home networks as well. UniFi offers more options than typical consumer-grade equipment. If you are a nerd who likes getting their hands dirty, or just want a network that performs better, UniFi is worth a look.

When Steve Jobs returned to Apple, in 1997, it had a conventional structure for a company of its size and scope. It was divided into business units, each with its own P&L responsibilities. Believing that conventional management had stifled innovation, Jobs laid off the general managers of all the business units (in a single day), put the entire company under one P&L, and combined the disparate functional departments of the business units into one functional organization. Although such a structure is common for small entrepreneurial firms, Apple—remarkably—retains it today, even though the company is nearly 40 times as large in terms of revenue and far more complex than it was in 1997. In this article the authors discuss the innovation benefits and leadership challenges of Apple’s distinctive and ever-evolving organizational model in the belief that it may be useful for other companies competing in rapidly changing environments.

The initial requirements were quite straightforward: build docker images, write Helm Charts, write Terraform code, and deploy on Kubernetes. Well… it turned out there was much much more to it.

If you happened to visit those websites during Fastly's outage, you saw the relatively unhelpful error message below. As a frontend developer, my eyes scan error messages like these for numbers - in this case, the "503" - indicating that the error isn't my fault, and I can move on with my life.

The text on the blue connectors is a bit small in this rendition (it says “refers to”) – I might have to tweak that. The blue is designed to suggest a link (as on a Web page), which I can use to explain kaputt.

So, after a time working a lot here and on my business, I was with my healthy compromised and needed to choose between "keep my open source project" or "keep my mental and physical health". And for me the choice was very clear, I choose me.

In the summer of 2009, I had an idea. My workdays were spent deploying tons of cloud infrastructure as Rackspace acquired Slicehost and we rushed to keep up with the constant demands for new infrastructure from our customers. Working quickly led to challenges with hardware and networking.

For folks familiar with Crossplane, you likely know that we adopt the design practice of using interfaces over implementations as frequently as possible. Even if we begin with an implementation, such as the current composition engine, we make sure to consider a future with potentially many implementations for the same functionality.

This started with a consulting snafu: Government organisation A got government organisation B to develop a web application. Government organisation B subcontracted part of the work to somebody. Hosting and maintenance of the project was later contracted out to a private-sector company C. Company C discovered that the subcontracted somebody (who was long gone) had built a custom Docker image and made it a dependency of the build system, but without committing the original Dockerfile. That left company C with a contractual obligation to manage a Docker image they had no source code for. Company C calls me in once in a while to do various things, so doing something about this mystery meat Docker image became my job.
