- Start Rust

Rust is a low-level programming language that can generate native binaries and Web Assembly code. It touts itself as being performant, reliable, and productive. The main idea behind Rust is to avoid as many runtime exceptions as possible, especially those related to memory access. For that reason, it provides an additional "borrow checker" that verifies that memory is used safely and throws errors at compile-time when it’s not: this adds a layer of complexity compared to most other languages. This focus is dedicated to understanding more about Rust in general and data ownership in particular.
- Lies we tell ourselves to keep using Golang
-
Here’s a list of lies we tell ourselves to keep using Golang:
- Others use it, so it must be good for us too
- Everyone who has concerns about it is an elitist jerk
- Its attractive async runtime and GC make up for everything else
- Every language design flaw is ok in isolation, and ok in aggregate too
- We can overcome these by "just being careful" or adding more linters/eyeballs
- Because it’s easy to write, it’s easy to develop production software with
- Because the language is simple, everything else is, too
- We can do just a little of it, or just at first, or we can move away from it easily
- We can always rewrite it later

I wonder if the proponents of LLM-generated code would argue that it’s not relevant if the LLM also maintain the code.

Very. Good. Point.
- What is OpenTelemetry?
-
I especially like the "What is NOT OpenTelemetry?" section:
- Not a Data Storage or Dashboarding Solution
- Not a Pre-configured Monitoring Tool
- Not a Performance Optimiser
- OpenTelemetry Autoinstrumentation in Java
-
Good foundational post. Nitpick: at some point, autoinstrumention was renamed to zero-code instrumentation.

I found lots of ideas in this post! In particular, I need to check Zigbee.

I like when people have an oblique viewpoint on things taken for granted.

- High-level concurrency in Kotlin Arrow
-
Coroutines are one of the most interesting features of Kotlin. However, the "coroutines standard library" sometimes falls short, especially when dealing with many suspended computations. Arrow provides those few additional functions that have proven useful in Kotlin code and other programming communities.

- Git experts should try Jujutsu

I installed it to check myself. I thought it would be compatible with Git repositories; it’s not:
jj logError: There is no jj repo in "." Hint: It looks like this is a git repo. You can create a jj repo backed by it by running this: jj git init --colocate
I’m curious, so I ran the command:
Done importing changes from the underlying Git repo. Setting the revset alias `trunk()` to `master@origin` Hint: The following remote bookmarks aren't associated with the existing local bookmarks: feature/newposts@origin how-to-batch@origin master@origin Hint: Run the following command to keep local bookmarks updated on future pulls: jj bookmark track feature/newposts@origin how-to-batch@origin master@origin Initialized repo in "."
If I rerun the log command, I get the following:

Jujutsu stores its config in a
.jjfolder. Removing it will get you back to the original state. I’ll probably come back to Jujutsu later if there’s critical mass in its usage.
