I'm using openobserve locally to monitor code agents and some internal tools. It works pretty well, it's a single binary and it has plenty of features (but it's not bloated yet)

Pro tips for debugging compilation times in GitHub workflows: - Use `cargo build --timings` to generate an HTML report. - Use the new GitHub feature to attach it as an artifact and browse it directly in GitHub. - Update Swatinem/rust-cache and check the logs github.blog/changelog/20...

I attended with my daughter the Oracle4Girls event in the local computer science university today. We need more events like this. Huge thanks to all the volunteers who made it possible ❤️

I have signed up some days ago but I didn't receive the newsletter and I don't have access to the link. Is that correct? No problem at all if it is, I just wanted to double check in case something isn't working as expected

Testing opencode with LimaVM as a sandbox. Being able to run `opencode serve` in the VM and `opencode attach` from the host is very handy. Good news: it still works with my Claude Code subscription

Closing an important phase today after three months working on projects at @fic-udc.bsky.social at @udc.gal. Grateful to the DB Lab and to the Green IA & algs chair for an inspiring journey. I’ll keep collaborating with the university but there are new exciting things ahead!

Been testing GitHub Copilot’s new coding agent for a few days. Integration with Issues, PRs, Actions, Codespaces, and the mobile app is impressive. Still prefer CLI-based code agents, the review/feedback loop is much faster

Neat trick: use watchexec to detect commits in your local repo and get notified when your code agent (running in a container) finishes its work.

I've created my first Firefox plugin that lets me share the current tab to @frontpage.fyi with minimal effort (mobile and desktop). It's also the first time I use @atprotocol.dev and it's as cool as it seems. The repo is available in Github but also in @tangled.org: tangled.org/@galiglobal....

What a special moment to speak at Current one last time about New Relic's object storage adoption for data streaming. Looking back at four years of performance improvements has been incredible, and I'm amazed by how much I've learned!

It took me ages to finish Database Internals. Very tough read, I almost give up a couple of times. It covers way too much for a 300 pages book. Yet, it's great to have a book on the topic and I appreciate all those links to papers and references to OSS systems

AWS MSK and Confluent Cloud support? Check! In combination with the Java Agent Kafka monitoring, it's like peanut butter and jelly for your streaming stack. Battle-tested internally and ready to roll. More integrations incoming, and hopefully a little squirrel 🐿️ at some point

"We utilize the ‘island model’ for deploying our Flink jobs, where all dependencies for a given application reside within a single region" After 4 years using this approach, it's my default choice nowadays (but isolating at the AZ level instead of region). netflixtechblog.com/introducing-...

Iceberg FileIO is very interesting to optimize Object Storage reads/writes. I'm working on similar optimizations but the edge cases are tricky. I wonder if someone has already used it without Iceberg for similar use cases www.tabular.io/blog/iceberg...

Built a tool using GraalVM for native compilation and Langchain4j with Ollama/Mistral to parse command outputs and generate readable summaries. When tests fail, it pipes the processed data back to NeoVim/Copilot to suggest fixes. And yes, I'm doing it because it's fun. No regrets.

This weekend's project: adding native Vim diff support to CopilotChat.nvim. The plugin is fantastic, but I felt it was missing this feature. The ability to use Vim shortcuts for reviewing LLM output offers a real productivity improvement!

I've successfully gotten the #ForSt State Backend working, both locally and with S3. It's a bit of a pain because it requires activation for DataStreams when using enableAsyncState(). The SST files are visible now. I'll next try to open them from a separate process (no Flink) as secondary instances

I've been exploring Flink's new Disaggregated State Storage (FLIP-423). It designates object storage as the authoritative source for state, enabling direct querying. Local disks are no longer mandatory but can serve as a local cache. Early proof-of-concept results show promising performance:

TableDescriptor is definitely my favourite way to create tables in Flink with the Table API because of the type safety and connectors options discoverability

There's a clear trend to migrate from Avro to Protobuf for streaming pipelines. This presentation by Uber was a great example. They showed several improvements they are contributing to Flink to make it possible: www.flink-forward.org/berlin-2024/...
