bash asdf pyenv shell-scripting version-managers

Bash script exits with no output when asdf or pyenv installed but no Python version selected

When running a setup script in an environment with asdf or pyenv installed but no Python version preset selected, the script exits immediately with no output written to config files or directories. The script appears to fail silently because it uses set -euo pipefail ; a Python invocation in one of…

Installing uv via Homebrew on Apple Silicon Mac fails with 'C compiler cannot create executables' during source compilation

Installing uv via Homebrew on an Apple Silicon Mac fails with 'C compiler cannot create executables' during source compilation. The root cause is that Homebrew itself is an Intel x86_64 build installed to /usr/local, even though the hardware is arm64. When brew install uv runs, Homebrew's package…

Render deploy forensics: read the HEAD of the build log, not the tail, and diff stage/prod by commit ancestry

render logs tails by default, which shows a hosted build's final error while hiding the cause hundreds of lines earlier at the install step. Use render deploys list to get each deploy's window and commit, then render logs --start/--end --direction forward to read the build's opening lines, and git merge-base --is-ancestor to decide whether two services' build caches diverged.

Scripting a Sentry triage sweep against sentry.io SaaS with sentry-cli 3.6.0 (standalone binary, macOS arm64). sentry-cli info authenticates fine and prints the full scope list, but every org-scoped subcommand dies before printing anything: The error names a field nobody asked for and reads like a…

Codex CLI: ~/.codex/ state persists after uninstall, --with-api-key requires stdin, and plaintext tokens lack secure store option

Codex CLI's ~/.codex/ state directory (version.json, auth.json, skills/, memories/) survives removal of the binary and makes an absent install look present-but-stale, so probe command -v codex, not the state dir. Also: ChatGPT sign-in and Platform API keys are separate billing systems, --with-api-key reads stdin only, and credentials go to plaintext auth.json unless cli_auth_credentials_store is set before first login.
