The Newsroom collects it all; each section below is also its own landing: Hacks · Tools · Field Notes · The Wire.

Hacks

• A Jekyll Dockerfile That Builds on Ruby 2.7: Pinning Past the Version Wall
• A reusable GPT-4o system prompt for dark-to-hopeful satire (and how to adapt it)
• A robots.txt That Actually Works on Jekyll (and the sitemap line people forget)
• A searchable, sortable Jekyll sitemap from your collections with no plugins
• Auto-deploy a Jekyll site over FTP from CI (the Travis recipe, legacy but real)
• Build a Jekyll sidebar that lists a collection's files and folders
• Count what happens most: the sort | uniq -c tally (and why uniq lies until you sort)
• Dark mode in a dozen lines, and the accent color that only passes WCAG in one theme
• Docker from zero: the dozen commands that actually get a container running
• Document Scraping in Python: BeautifulSoup, Playwright, and the Failure Modes That Bite First
• Fix the tofu boxes in your terminal prompt: install a Nerd Font, then prove it actually stuck
• Fork, build, and run a VS Code extension locally: the Front Matter dev-environment playbook
• Four fzf shell functions you'll actually keep: kill, branch, cd, open
• Front Matter Placeholders: Stop Frontmatter Drift Before the Validator Sees It
• Hide Your Navbar on Scroll Down, Bring It Back on Scroll Up
• Host a Site Free on GitHub Pages: Repo, Jekyll _config, and a Custom Domain
• It works on macOS, breaks in CI: bash 3.2 vs declare -A
• Kill dead links in Jekyll: stable permalinks, redirect_from, and a CI link checker
• Let git find the commit that broke it: git bisect run
• Let the content bot edit posts, not your CI: a changed-files allowlist gate
• Make a bootable Debian 13 USB from a Mac: dd, one checksum, one password
• Make bash fail loudly: the set -euo pipefail header
• Make tmux survive a reboot, not just a disconnect
• Make your bash scripts clean up after themselves: trap … EXIT
• Make your shell remember where you were (without a productivity app)
• New Django project to first GitHub push, without committing your secrets
• One .tmux.conf line per real annoyance: the config that grows up
• One mkdir, many folders: brace expansion (and the space that silently breaks it)
• Order your Dockerfile so the layer cache does its job (and the whitespace edit that busts it anyway)
• Pipe find into xargs without splitting your filenames in half
• Prompt patterns that survive a code review: RCTF, few-shot, and a reusable Copilot template library
• Read a failing CI run from your terminal: gh run --log-failed (and the watch trap that ships red builds)
• Read a file's first 16 bytes: walk a magic number with hexyl
• Read the query plan before you add the index: EXPLAIN ANALYZE, Seq Scan vs Index Scan
• Rebase your messy commits — before you push, never after
• Rotate the secret you already deleted: the key still living in git history
• Run type -a before you alias, so you don't shadow a command you needed
• Run your data load twice on purpose: the upsert and watermark that survive a retry
• STRIDE your side project in 20 minutes: one diagram, six questions, a ranked fix list
• Scaffold a VS Code extension in five minutes: yo code, F5, ship
• Scope the token before your MCP server gets the keys: a fine-grained PAT that can't touch prod
• Scope your GitHub Actions token before it can write to everything
• Sign your commits with GPG for the Verified badge (and why GitHub still says Unverified)
• Stop 'works on my machine': anchor every script to its own directory
• Stop copy-pasting bash logging: a sourced lib with a reload guard
• Stop fighting Excel: grep, awk, and a month-end close for million-row CSVs
• Stop forgetting your own build commands: a Makefile as your project's command menu
• Stop retyping the same 12 git commands: a .gitconfig alias starter pack
• Stop scrolling CI logs: write a real summary to $GITHUB_STEP_SUMMARY
• Stop shipping tarballs that explode: archive the directory, tar tf before you extract
• Stop stashing to switch branches: check out two at once with git worktree
• Stop the KeyError: defensively parsing tool JSON in Python
• Stop typing IP addresses: the ~/.ssh/config block that names your servers
• Stop your workflow from triggering itself: the bot-author skip guard, stress-tested
• Tangle a markdown file into runnable scripts, one file per fenced language
• The gh CLI doesn't get GITHUB_TOKEN for free: set GH_TOKEN in env
• The work/ directory pattern: cache inputs, regenerate outputs, stop flaky CI builds
• Threat-model your dotfiles: what a stolen laptop actually gets
• Threat-model your rollback: the migration downgrade nobody tested until 2am
• Two GitHub Actions workflows that lint, test, and package a VS Code extension
• Undo almost anything in git: the reflog is your undo history
• Validate a DataFrame before it poisons the table: a pandera schema and a quarantine bin
• Version-control your CV: LaTeX, VS Code, and the .gitignore that hides the build mess
• WSL2: a real Linux dev box on Windows in about ten minutes
• When a Yanked FFI Gem Breaks Your Jekyll Docker Build: One Bundler Command
• Why your CI script hangs forever: wrap --version in timeout
• Wrap your scary shell scripts in Gum: a three-layer 'glass interface'
• Write your page shell once with Jinja2 inheritance — without leaving an XSS hole open
• You can't gate a workflow step on a secret in if: — promote it to an env first
• Your 80% coverage badge is lying: gate on branches, not just lines
• Your Django page fired 51 queries: I counted them, then killed the N+1
• Your connection pool is too big: size it by cores, not hope
• Your first React app with Vite: components, props, and a useState counter
• Your loss climbs back up and it isn't the learning rate: the zero_grad() line the loop can't skip
• chmod 644 and 755, never 777: the permission bits that decide what's safe to run
• fzf -m: the multi-select functions, and the one time you don't quote
• jq's // default silently eats your false values
• rsync without nuking the wrong directory: the trailing slash, --delete, and -n
• tmux in 9 commands: the survival subset

Tools

• DuckDB: the honest review
• Note-taking apps: a to-do list with a subscription, reviewed
• The VS Code extensions I actually keep installed (and the one-liners to install them)
