Developers, you don’t need to ask permission…

Reading the “The programmer as decision maker” by Mark Seemann hit a nerve with me. You didn’t read it yet? Ok, go do that first….

…. Done reading? Ok, let’s add my 2 cents on it. I completely agree with the statement that Mark tries to make. Every day in a programmer’s life is combination of micro- and macro decisions. Unfortunately programmer’s are not always aware that they are making these decisions giving them the feeling there are not in control. This is really sad especially if you know that the 3 things that motivate us the most are ‘Autonomy’, ‘Mastery’ and ‘Purpose’. We as developers have the luxury that we can quite easily achieve all 3 but we are not aware that these things are in our control…

I sometimes here statements like; “Everything is decided for me”, “I’m not involved in the decision making”, “Our PM will never allow us to do X” where in fact these people are already making decisions(good and bad) all the time.
So I would say to all developers out there; “Embrace the power that you have and stop thinking you need to ask permission…”



And of course I have to repeat the Grace Hopper quote:
"It's easier to ask forgiveness than it is to get permission."
Grace Hopper
PS: If anyone from my team is reading this, don’t forget to ask my permission first before you start applying this 😏

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
