Following the recently published article on Cloud Native Sustainability: Strategies for carbon reduction the Agile meets Architecture conference team has now published the recording of my talk on the topic. In it I go over the most important concepts of green computing, I explain how organisations are estimating the carbon emissions related to their cloud usage, and I offer some insights into…
Over the past year I’ve spent a fair amount of time getting my head around green software and what role cloud computing plays in that space. There’s a talk that I’m currently presenting at various conferences and events. If you just want the essentials there’s now an article that I wrote with my colleague Seema: Cloud Native Sustainability: Strategies for carbon reduction . In the article, we…
Seeing all the experiments with GitHub Copilot around me I decided to take Copilot to some difficult terrain (pun intended, see below). A lot of the positive experience is reported with very common programming languages, JavaScript and Python especially, writing code related to web applications. But how would Copilot fare with a less common language and code that’s involving more complicated data…
The podcast team at the Handelsblatt newspaper invited me to an episode of their So klingt Wirtschaft podcast. Jana Samsonova and I talk about green computing, responsible use of technology, and how moving to a public cloud can reduce CO 2 emissions. As you may have guessed at this stage, the podcast is in German.
When I started OCMock almost 20 years ago, I would never have expected it to become so popular. Then again, at the time Objective-C was a niche language used only to develop (some) applications for the Mac. This changed with the iPhone, and dramatically so. And it changed again in about 2016 after Apple had introduced Swift and had made it very clear that Objective-C had not much of a role to play…
Developer experience platforms have been a hot topic for a while now, and I've talked about them with many of our clients. Last year, I distilled the essence from those client presentations into a talk that I gave a GeeCON Prague, and now the team have made the recording of the talk available on YouTube. DX platforms are not as hyped at Gen AI but if you want to make your developer teams more…
In this article, published in the funkschau magazine, I discuss an important issue that our modern software supply chains bring when it comes to security: the role of the sprawling web of dependencies. You can read the article in the online edition of the magazine on page 42. Sorry, no direct link, and the text is in German.
Travelling is part of being a consultant, and speaking at conferences added an extra amount of travel for me. The Covid-19 pandemic changed this quite dramatically, and looking back at 2022 I am wondering what the “new normal” could be after the pandemic. The chart above shows some key figures related to my business travel over the past eleven years: the numbers of trips, cities, and countries I…
As I have mentioned before , I like writing screen savers. This time I revisited one that I wrote over twenty years ago. At the time I had decided to spend a week in a small town on the Costa Brava in Spain. Two things happened: 1) On the way out I stopped by friends in Barcelona, where I flicked through the book Maeda and Media , and 2) I had brought my Apple PowerBook with me. One of the…
Twitter’s policy changes seem increasingly erratic—like suspending accounts of journalists (see this article on The Guardian for example) or banning references to Mastodon accounts (as reported by Martin for example). Both policy changes were reverted by the way. For now. All this makes me wonder how long I want to remain on Twitter. For now, I’ve decided to keep my Twitter account but to post on…
