TL;DR Claude Code sessions on the same machine can now list and message each other.

TL;DR Link to heading Library lending apps hand out .acsm files, which normally need Adobe Digital Editions to turn into a readable epub.

TL;DR This is about Claude’s scheduled cloud routines specifically, which is the only agent platform I have tried it on.

TL;DR Link to heading Put a long signed token in an email link and you have built a bug that fires deterministically for some recipients and never for others.

TL;DR Link to heading My OpenClaw gateway went silent for three days after a usage spike, even though I could still chat to the same provider via its web interface normally.

TL;DR: During a migration across a few dozen repos, “looks done” failed me three different ways: stale code search, stale local clones, and an auto-merge that quietly reverted my changes.

TL;DR: I needed to repoint a batch of uv projects at a new package registry without changing a single resolved version. uv lock --no-upgrade re-resolves anyway when the index changes, so I rewrote the URLs in pyproject.toml and uv.lock with sed and verifi…

TL;DR Link to heading I moved object ownership in Postgres from a shared role to a dedicated role per service, one environment at a time, with the application serving throughout.

TL;DR Link to heading I had a Kubernetes service exposed via two different gateway flavours on different clusters.

TL;DR Link to heading I had reduced my OpenClaw heartbeat cadence a few weeks ago expecting a big drop in LLM credit usage.

TL;DR Link to heading A private GKE cluster’s outbound traffic to *.googleapis.com and *.pkg.dev flows through Cloud NAT by default and pays $0.0385/GB data processing on every byte, in both directions.

TL;DR: A common haproxy-in-front-of-redis-sentinel setup has three reliability traps: liveness probes cascading during sentinel failover, haproxy hard-stopping inflight connections on SIGTERM, and haproxy aborting at startup when any redis pod’s DNS is NX…

TL;DR Link to heading A cleanup PR removed an accidental guard in our release workflow’s git push logic.

TL;DR: I’ve been using Claude Code since last July and spent most of that time correcting the same behaviours every session.

TL;DR: I thought there was.

TL;DR Link to heading My OpenClaw gateway kept calling an LLM provider I had retired.

TL;DR: Putting ~/.openclaw in a private git repo is mostly about writing the right .gitignore and keeping every secret outside the tree.

TL;DR Link to heading A Go channel is one primitive covering what other languages split across locks, condition variables, semaphores, and queues.

TL;DR: Upgrading from 2026.4.8 to 2026.4.15 tripped two restrictions that silence your config without a loud error: a tightened schema for tools.elevated.allowFrom.telegram that invalidates the whole file when it fails, and an fs-safe layer that refuses to

TL;DR: I wanted Claude Code to read out each response through say on macOS so I could step away and listen instead of watching the terminal.

TL;DR: A pre-upgrade hook applies resources that stay applied when the upgrade fails and you roll back.

TL;DR — I did a hot sauce making course at Easton Chilli in Bristol.

TL;DR: OpenClaw can call Claude and Codex through their CLI tools instead of hitting APIs directly.

TL;DR: I moved my OpenClaw setup from a Jetson Nano to a VPS.

OpenSSH 10.2 warns you when a connection isn’t using post-quantum key exchange.

TLDR: Enabling uniform_bucket_level_access on a GCS bucket disables the legacy role bindings that project owners rely on for object access.

TL;DR: Anthropic accidentally shipped the Claude Code source map; I went through it looking for patterns worth borrowing.

I spent a couple of days migrating our monitoring stack from self-hosted kube-prometheus-stack (KPS) to GKE’s native Google Managed Prometheus (GMP).

TLDR: VPA’s updater defaults to requiring 2 replicas before it will evict a pod.

TL;DR — I switched from an Apple Watch to a Garmin and wanted to bring my workout history with me.

TL;DR: If Spotlight can’t find your apps, rebuild the Launch Services database with lsregister.

TL;DR: jj (Jujutsu) is a Git-compatible version control system with some interesting ideas — automatic change tracking, universal undo, and a different take on history editing.

TL;DR: Jetson Nano is old and stuck on Ubuntu 18.04-era software, but it’s still a great always-on host for bounded edge workloads like OpenClaw.

TLDR: Mutating admission webhooks that inject scheduling rules (nodeSelector, tolerations, affinity) persist on StatefulSet pods even after you clean the StatefulSet template.

I use git worktrees heavily for parallel development.

TL;DR: Feed your entire git log + file lists into a single LLM call to generate a bash hash map of conventional commit messages, then apply it with git filter-branch in seconds. 143 commits rewritten in 6 seconds, one API call, ~$0.05.

This is a follow-up to my original post, Installing OpenClaw on a Jetson Nano, where I got things working with Bun on Ubuntu 18.04.

TLDR: Go doesn’t auto-detect container memory limits.

I recently learnt something about BigQuery pagination that I wish I’d known sooner.

Happy lets you control Claude Code sessions from your phone.

TLDR: If you manage SendGrid DNS records in Cloudflare, make sure PTR-related records are set to DNS-only.

I migrated a few Python projects from Poetry to uv.

TLDR: If your entrypoint script doesn’t use exec, SIGTERM never reaches your Python app and graceful shutdown silently does nothing.

TLDR: --mount=type=cache makes RUN layers non-deterministic.

I have a Jetson Nano at home that I SSH into from my laptop.

The idea of messaging an AI assistant from my phone while I’m out walking and having it write code that I can steer — “try this approach instead”, “add tests for that edge case”, “actually scrap that, let’s do X” — is genuinely exciting.

I connected my Jetson Nano to an external projector and the console text was microscopic.

TLDR: HPA handles horizontal scaling on CPU, VPA right-sizes memory.
