Working through the https://t.co/Qeouv8SjFx distributed systems challenges has been a lot of fun.
For the broadcast problem, I ended up implementing a k-tree broadcast topology. Each node only forwards messages to its k children, creating a one-way flow and avoiding duplicate msg

@brankopetric00 Agree with the advice. One nuance for Node.js: it's easy to assume that since the event loop is single-threaded, a "cpu: 1" limit is sufficient. But, GC threads and libuv workers share the same cgroup quota, so short CPU bursts can still hit the limit and trigger throttling.

@avrldotdev Hey, The edge cases of the distributed replication makes RAFT really fun to implement. Sharing my implementation for reference: https://t.co/psgkp8aB2A

The industry has gone completely nuts.

Use tokens to generate AI code and documentation slop. Then use even more tokens to understand and review that slop.

Then judge engineers by token usage instead of how empathetic and clear their docs and code actually are, and completely neglect human comprehension.

Utter nonsense.

@amuldotexe Something similar I’m building for a custom PR reviewer AI agent.
Using the gh CLI to extract learnings from reviews and store them as embeddings so every review doesn’t start from scratch. The agent queries this KB during reviews and updates it with feedback from PR over time.

please shut the fuck up i don't even care about the specific thing you're saying i'm just so tired of hearing predictions one after the other telling me what the future is going to be like just please shut the fuck up

@mrkaran_ Working on a similar idea: a Slack bot that ingests alerts from Alertmanager and starts an agent session with restricted Grafana MCP access. Each alert bootstraps the session with alert-specific context so the agent can help triage incidents faster.

I wrote a book for engineering leaders.

The Agentic Engineering Guide. 10 parts, 33 chapters. Context engineering, authorization, cost control, sandboxing, evaluation, governance, adoption playbooks.

Not a prompt tutorial. The decisions you face when shipping agents to production this quarter.

Early version. Open source. Rough edges included. Spot a mistake, open a PR.

@amuldotexe @sneha_prabhu Amazefit helio strap is a cost effective way to get same sort of metrics very very accuratly considering its price point.
But it remains out of stock most of the time, got one unit luckily and its very accurate but yes lacks some of the premium features of whoop.

[Harsh Rai @harshrai3]

Recently hit intermittent 503 UC errors in Istio that didn’t surface well in metrics and were hard to debug. Traced it down using logs & tracing: root cause was idle connection reuse between Envoy and the app.

@Siddhant_K_code This is one the best and the most relatable thing I have read in a while.

Computer Networking Fundamentals (mini-course)

Everyone who wants to understand container and Kubernetes networking should start from the basics. This heavily illustrated free course walks you through the first two layers of Computer Networking: Ethernet and IP.

A must for any developer or DevOps engineer who wants to build a solid understanding of computer networking before they move to the higher-level protocols like TCP, UDP, and even HTTP.

@arpit_bhayani "This was a clean-room implementation (Claude did not have internet access at any point during its development);"

@SumitM_X Had to debug one such scenario at work recently.
Documented the 503 issue in our case here: https://t.co/SFwdrapHCP
