-
-I have been in incidents. Understandably, everyone wants the issue to be resolved as quickly and others want to know how long TTR will be. IMHO, providing no estimates at all is no solution either. So maybe give a rough estimate but clearly communicate that the estimate is rough and that X, Y, and Z can interfere, meaning there is a chance it will take longer to resolve the incident. Just my thought. What's yours?

-
-Reading this post about `#rust` (especially the first part), I think I made a good choice in deciding to dive into `#golang` instead. There was a point where I wanted to learn a new programming language, and Rust was on my list of choices. I think the Go project does a much better job of deciding what goes into the language and how. What are your thoughts?

-The opposite of `#ChaosMonkey` ... automatically repairing and healing services helping to reduce manual toil work. Runbooks and scripts are only the first step, followed by a fully blown service written in Go. Could be useful, but IMHO why not rather address the root causes of the manual toil work? `#sre`

-
-Looking at `#Kubernetes`, it's pretty much following the Unix way of doing things. It has many tools, but each tool has its own single purpose: DNS, scheduling, container runtime, various controllers, networking, observability, alerting, and more services in the control plane. Everything is managed by different services or plugins, mostly running in their dedicated pods. They don't communicate through pipes, but network sockets, though. `#k8s`

-I like the idea of types in Ruby. Raku is supports that already, but in Ruby, you must specify the types in a separate .rbs file, which is, in my opinion, cumbersome and is a reason not to use it extensively for now. I believe there are efforts to embed the type information in the standard .rb files, and that the .rbs is just an experiment to see how types could work out without introducing changes into the core Ruby language itself right now? `#Ruby` `#RakuLang`

-
-In Go, passing pointers are not automatically faster than values. Pointers often force the memory to be allocated on the heap, adding GC overhad. With values, Go can determine whether to put the memory on the stack instead. But with large structs/objects (how you want to call them) or if you want to modify state, then pointers are the semantic to use. `#golang`

-
-I found that working on multiple side projects concurrently is better than concentrating on just one. This seems inefficient at first, but whenever you tend to lose motivation, you can temporarily switch to another one with full élan. However, remember to stop starting and start finishing. This doesn't mean you should be working on 10+ (and a growing list of) side projects concurrently! Select your projects and commit to finishing them before starting the next thing. For example, my current limit of concurrent side projects is around five.

To summarize: I am using it together with the terminal multiplexer `#tmux`. It doesn't bother me that Helix is purely terminal-based and therefore everything has to be in the same font. `#HelixEditor`
