Thinking more on this, I think we should all be a bit nervous about GitHub, commercially-owned center of gravity of the majority of our open-source communities

When We Get Komooted Following the sale of Komoot to private equity, Josh Meissner explores the broken relationship between corporate capital and our communities...

Great post about companies built on user-created data selling out for profit at the expense of the community that built around them. Shades of @yanisvaroufakis.bsky.social 's techo-feudalism

I used to use this - rather than getting a fancy KVM, you get a cheap switchable USB hub, and run a piece of software on one of the machines that switches the display inputs whenever it disconnects (because you pushed the switch)

Worked pretty well, and you get proper native display connections!

This one was pretty tame; I have had some fairly big changes to match. It must be an enormous ongoing burden for projects like clippy which are _MUCH_ bigger.

avoid suggesting traits from private dependencies by Qelxiros · Pull Request #143038 · rust-lang/rust fixes #142676 fixes #138191 r? @tgross35

For pup 0.1.3, which I released this morning there is only one impacting change - rustc/143038. This change sees a function on one of the IRs - "all_traits" - renamed to "all_traits_including_private" - to make it clear to the caller that it may be inappropriate in some user-facing output

This is because pup needs to use rust nightly to access the interfaces and APIs needed to walk over the IRs of the project it is linting. And all these APIs are unstable, internal things (this is also how clippy works!).

A fun part of working on cargo-pup, an architectural linting tool for #rust, is that I have to periodically fix things up to match changes in rustc's codebase. Little peaks behind the curtain into the compiler's internals.

GitHub - DataDog/cargo-pup: Pretty Useful Pup let's you write assertions about the architecture of your Rust project Pretty Useful Pup let's you write assertions about the architecture of your Rust project - DataDog/cargo-pup

I’ve been working on cargo-pup, a Rust tool for defining and enforcing architectural rules in your codebase - like ArchUnit for Java, or Clippy, but for project-specific architecture constraints rather than linting.

Would love feedback from other rust folks!

What is this I must have it

Combining OpenTelemetry and Java auto-instrumentation Combining OTel and auto-instrumentation for sweet-spot instrumentation

Wrote a bit more about this here --> was my _monday morning discovery_

blog.scottgerring.com/posts/opente...

This way you get the best of both worlds - auto-instrumentation of _all the things_ you want auto-instrumented - HTTP and DB clients, Java frameworks, and so on - but maintain the flexibility to mark up your spans _without_ the ceremony or deps of a full OTel exporter setup!

Did you know that you can use the OpenTelemetry Java APIs without setting up an export pipeline in your code? (I didn't)

Add the opentelemetry-api dep, sprinkle @WithSpan on your important business-things, and let your auto-instrumentation wrapper - e.g. dd-trace-java - discover the OTel API usage!

Custom static analysis for your apps with CodeQL Building project-specific static analysis rules with CodeQL to catch architectural violations and project-specific anti-patterns

I've been playing around with CodeQL as a tool to write project-specific lint rules. It's an amazing tool in general, but feels kinda tedious for this sort of project-specific thing, BUT it works! -->

I for one welcome our new AI overlords

On Thursday the 19th of June, I'll be at @lu.voxxeddays.com talking about the terrible things you can find if you look below the happy easy friendly world of Java - into the linuxy bits underneath. _I_ think this stuff is interesting, and now I hope to make it interesting - perhaps even useful!

Imagine a world where the entshitifcation of all content on the internet by GenAI slop and SEO fuckery leads to folks logging off and going to talk to their neighbours

I vibe-coded a path tracer so you don't have to And it worked, ish. Exploring the boundaries of AI-assisted coding through ray tracing.

Like everyone else with a keyboard and a programming habit, I've been experimenting with coding assistants. But I'm pretty skeptical of using them for anything chunky - so I thought, what if we push this way beyond its sensible bounds?
Let's build a path tracer without any human code using claude!

Hey the sky is there! Is that normal? Be honest.

Well great. I must’ve had a 5 year winning streak there

Fixing the com.horror package 😂 with @scottgerring.com at VoxxedDays Zürich #VDZ25

@fmartin.ch is in the field real user testing your systems!

Great talk from @garnier.wf with a step by step intro to SSO + spring ! Also, excellent type safety banter 🤪

#VDZ25 just started. New record with 688 participants! Yay!

As I've spent a bunch of time staring at #OTel Rust PRs, I thought i'd write a thing about OTel's notion of Context - what it is, and how it flows through services.

It's a core abstraction of OTel and an interesting thing to learn about if you're into APM!
