Streamlining local development with Dnsmasq

Testing on localhost hides entire categories of bugs—cookie scope issues, CORS policies, authentication flows that behave differently on real domains. These problems surface after deployment, when fixing them costs hours instead of minutes. Dnsmasq eliminates this gap by making local development behave like production, turning any custom domain into localhost whilst preserving domain-based security policies.

SSH dotfiles: unlocking efficiency

Managing dozens of SSH connections means remembering complex hostnames, multiple keys, and elaborate commands you copy from text files. The .ssh/config file transforms this chaos into memorable aliases that map mental shortcuts to complete configurations, reducing cognitive load so you can focus on actual work rather than SSH incantations.

Dotfiles: why and how

Working on someone else's machine feels like writing with their hands—common commands fail, shortcuts vanish, and everything feels wrong. Dotfiles transform this by capturing your accumulated workflow optimisation in version-controlled configuration files, turning any terminal into your terminal within minutes rather than days of manual reconfiguration.

Downtime of uptime percentages, deciphering the impact

Understanding the real-world implications of uptime percentages is paramount for businesses and consumers alike. What might seem like minor decimal differences in uptime guarantees can translate to significant variations in service availability, impacting operations, customer experience, and bottom lines.

cURL beyond GET: an HTTP toolkit you already have

curl offers around 257 command-line options, yet it is easy to use only a small handful of them in regular rotation. This article treats the familiar URL fetcher as a practical HTTP toolkit for debugging, scripting, and smoke tests.

Leap seconds: the extra tick that breaks everything

Leap seconds are tiny corrections with large software consequences. This article explains why UTC occasionally gained an impossible second, how Linux, DNS, airline bookings, and distributed systems stumbled over it, and why standards bodies chose a different future.

Resume-driven architecture: when career incentives overwrite system needs

Resume-driven architecture happens when teams choose technology for marketability rather than fit. It is not individual vanity so much as an incentive problem built by hiring, promotion, hype, and weak technical governance.

Aliases and shell functions: building your personal command vocabulary

The average developer types the same handful of commands hundreds of times a day, with the same flags, in the same order. The shell has two small features for shortening that vocabulary without losing any of its expressiveness, and they take an afternoon to learn properly.

The documentation graveyard: why we write docs to forget them

Documentation graveyards are not created by engineers who hate writing. They are created by organisations that treat knowledge as a one-off clean-up task instead of maintained product infrastructure.

jq: a Swiss Army knife for JSON on the command line

Most developers meet jq as a pretty-printer and go no further. Underneath that single command is a filter language rich enough to reach into nested JSON, reshape an API response, and build request bodies, all composable with Unix pipes and all comfortable inside a one-liner.

Floating point: the maths your computer quietly gets wrong

Most developers learn that 0.1 plus 0.2 looks strange, then quietly file it under language trivia. The real lesson is sharper: computers do not store numbers the way humans write them, and consequences compound.

Git worktrees: parallel branches without the stash juggling

A colleague asks for an urgent review whilst a refactor is halfway across the working tree. The usual ways to juggle parallel branches are all bad: a panicky git stash, a second clone that drifts out of sync, or a polite request to wait.
