If you ever need to figure out what's going on in your system, check the /proc folder.
Aivars Kalvāns walked us through the proc filesystem and showed us where to find everything from the arguments a process was started with to its open network connections.

Finally a solution to the 💩 in 💩out issue all observability tools face.
@dominik.suess.wtf showed us how OTel Weaver can ensure different teams use the same names and data types for the same kind of data.
It uses metric defintions to generate code / docs / dashboards

How do you find issues that involve your service mesh's side car proxies?
You need to make them less transparent and include them in your traces.
Konrad Renner showed us how it's done at #CloudNativeDaysAustria

You might not need to build your own controller for custom resources.
Instead you could use KRO and its resource graph definition as @yveshwang.bsky.social showed us.

She explained why DX still matters and how to communicate this to your management.
Pro tip: use the venn diagram from her presentation 😉

Today @t-sc.eu shared his learnings from karriere.at about how platform engineers can actually improve the experience for developers (especially of microservices) instead of just forcing them to learn yet another tool.

Great talk! It always helps to understand where the purpose of one tool ends and others need to take over.

Sarah Christoff gave us a nice refresher about solving deadlocks.
I wouldn't have considered the resources themselves to be part of a possible solution (by requiring certain procedures to update their state)

Another interesting talk from todays #codecrafts vienna conference.
Bjorna Kalaja raised awareness for Green Software Principles and ran through different kinds of common refactorings.
E.g.: It pays of to simplify your data models to save energy.
Splitting your monolith has the oppsite effect.

Your team structure, software architecture, and business requriements are connected and need to evolve together to reach your target system structure.

@bitsbysigrid.bsky.social dove deep into how ESM modules make the injection of observability tools especially hard.

Use empty toilet paper rolls to keep your cables rolled up nicely.
Big brain move: Write the type or purpose of the cable on the roll to keep access times low.
If you have a better system let me know!

When this worked, my first thought was:
Go home, vitest! You're drunk.
But it makes sense once you understand that the hidden option refers to elements hidden from the accessibility tree.
In my case, I wanted to refer to an icon within a button.
How would you have named this option?
