Because I’ve been sitting in 100,000,000 meetings where people endlessly debate whether the monthly number of widgets is going up or down, or whether widget method X is more productive than widget method Y. For almost any graph, quantifying the uncertainty seems useful, so I started trying.

If Dev and Ops are one team, why don’t they share the same data? Everyone in tech is busy discussing Kubernetes, containers, and microservices as if the basics of DevOps and continuous delivery are all figured out. In practice, the classic blame game between dev and ops is still alive and kicking. We might be nicer to each other now with a common sense of shared ownership, but those niceties often hide the obstacles that are making it hard for engineers to move forward faster.

The organisational structure is extremely important for the success of any business. In this blog post, I will explore how a matrix organisational structure built in the style of a matrix organisation can harm your company. Before I continue, I want to clarify that there are some businesses that can apply this organisational structure with success—Spotify, for example. Spotify’s document about tribes and guilds became extremely popular in the Agile community.

The two positions are not interchangeable—and misperceptions of their roles can hurt teams and compromise productivity. It’s important to understand the differences between a data engineer and a data scientist. Misunderstanding or not knowing these differences are making teams fail or underperform with big data. A key misunderstanding is the strengths and weaknesses of each position.

For the system at work, I am on call one week every seven weeks. For most of the past ten years, I have been on organized on call rotations for the systems I have been developing. I think being on call is a logical way of taking responsibility for your work. You also learn a lot from it. However, it is stressful and an inconvenience, so you should get payed for it. Why Developers Should Be On Call. Many systems need to be available around the clock, so somebody has to be on call for support.

Do you have any files on your computer called something like DocFinalFinalFinal1_2.pdf ? If you do, then you probably already understand the basic value of version control. By saving each version as a new “final” version, rather than overwriting the previous final version, you can not only distinguish between different versions of the same document, but ensure that previous versions aren’t lost forever.

While at the time, the company decided not to go with GraphQL, it was only a year later that they revisited the idea and started to make it part of their core technology strategy (they had multiple mobile apps and 3rd party clients that needed a more performant interface than the REST API, which had some performance issues).
