2026Hotkey setup for VSCode's nextEditor cycles tabs across all split groups#vscode #keybindings #productivity1
Setting up Hermes Agent as a persistent Discord bot on a VPS, using an existing Claude subscription#hermes-agent #discord #anthropic #systemd2
Pinning k3d node IPs so a Colima restart doesn't break your cluster#k3d #colima #kubernetes #terraform3
Learning from what CockroachDB's Pebble repo actually does in CI#ci #testing #go #github-actions5
Caddy can front multiple local k3d clusters on one port, with free automatic HTTPS#caddy #k3d #kubernetes6
Claude Code can run perpetually on a VPS with Telegram#claude-code #vps #mcp #systemd5
mini.files lets you rename, create, and delete files by editing directory buffers like text#neovim #mini.files #file-explorer5
Setting up gcloud with separate personal and work accounts in fish + starship#gcloud #fish #starship13
Unquoted variables in fish's `test`/`[` cause 'Missing argument' errors in completion functions#fish #gopass #shell7
Bitbucket Server doesn't generate heading IDs, so TOC anchor links silently don't work#bitbucket #markdown #git13
Starship context_alias uses Rust regex — $1t is parsed as group named "1t", not group 1 followed by "t"#starship #regex #kubernetes6
cp -r creates the destination directory if it doesn't exist (in the two-operand case)#shell #posix #cp8
os.Exit should only ever be called from main in Go#go #cli #error-handling10
Enterprise Anthropic-compatible gateways reject the SDK's custom headers#anthropic #python #enterprise-gateway2
`go install .` installs the current module from local source, not the registry#go #cli2
yq can parse XML, including JaCoCo coverage reports#yq #jacoco #maven13
git filter-repo is the modern replacement for filter-branch for rewriting commit history#git #productivity7
PVCs cannot be shared across separate Kubernetes clusters#kubernetes #storage #k3d3
Airflow 3 Celery workers crash silently when REMOTE_LOGGING=True but aws_default connection is missing#airflow #celery #kubernetes3
Use filesha256 triggers on Terraform null_resource to detect file changes#terraform #null_resource3
godoc breaks with Go modules — use pkgsite instead#go #godoc #tooling2
make install PREFIX installs everything under one directory, not just the binary#make #linux #cli7
make won't regenerate config.h after a branch switch unless you run make clean#make #c++#build2
helm upgrade does not restart existing StatefulSet pods when the pod template changes#kubernetes #helm #statefulset5
Airflow 3 with MySQL 8.0 fails because Flask-AppBuilder uses CREATE INDEX IF NOT EXISTS#airflow #mysql #flask-appbuilder7
spring.config.import: configserver belongs in profile files, not application.yml#spring-boot #spring-cloud-config #java7
Disabling Spring Cloud Config Server in application-local.yml is too late — use a JVM arg instead#spring-boot #spring-cloud-config #java2
Use the MCP inspector to test stdio MCP servers interactively#mcp #go #debugging2
Go's cookiejar strips expiry metadata from cookies#go #http #cookies3
Airflow 3 CeleryExecutor workers need DAG files mounted on their own pod#airflow #kubernetes #celery16
Maven Surefire silently ignores test files whose names don't end in exactly 'Test'#maven #junit #jacoco3
In Spring Boot 3, the 'optional:' import prefix silences fail-fast: true for the config server#spring-boot #spring-cloud-config #migration3
How to run a local multi-cluster Kubernetes setup with Colima, k3d and Karmada on macOS#kubernetes #k3d #karmada #colima #macos4
Karmada member clusters need manual networking fixes when running on k3d + Colima#kubernetes #karmada #k3d #colima #airflow2
String.format() is preferred over + concatenation in Java, but the compiler handles simple cases#java #strings #performance2
git stash apply preserves the stash so you can apply it to multiple branches#git7
Running a cronjob on Kubernetes requires installing half the internet first#kubernetes #devops #k3d4
Classic Teams webhooks don't work in group chats — you need Power Automate + Adaptive Cards#teams #microsoft #webhooks4
javax.sql.DataSource doesn't move to jakarta — it's a JDK API, not Java EE#java #spring-boot #jakarta1
Killing gpg-agent fixes the keyboxd version mismatch warning#gpg #gopass #cli3
You can fetch a single file from a remote git repo without cloning#git #cli2
Two gotchas when pointing Crush at an Anthropic-compatible API gateway#crush #anthropic #api-gateway4
Caddy's handle_path strips the prefix before proxying; handle does not#caddy #nginx #reverse-proxy14
