Articles about software engineering, Odoo, cloud infrastructure and running a digital business.
Decouple the storefront from Odoo and you get a faster, safer, upgrade-proof shop. DragonflyDB caching, island architecture, GitHub version control, PR previews, VPN-isolated ERP, PWA mobile UX — everything we ship on every headless e-commerce project.
A limited run of 40 units sold 46 in eleven minutes, and nothing in the stack was broken — the storefront had been given a number and treated it as a guarantee. The four stock figures Odoo will hand you, why a band beats a number in the catalogue, and where the real fix lives: at the moment of commitment, not on the product page.
A disk alert at 94% on a database where nothing had been imported and nothing had been deleted. Why Postgres grows faster than your data, the single idle connection that had been quietly blocking every vacuum for eleven days, the autovacuum defaults that are expressed in the wrong unit on a large table, and the difference between bloat you can vacuum away and growth you have to agree a retention policy for.
A nightly export ran green for six weeks while sending nothing, because the API key it used had an expiration date on it and a housekeeping cron deleted the record the day after it lapsed. The three ways a credential dies, why only one of them is loud, and the register, the gauge and the authenticated probe that turn a surprise outage into a calendar entry.
A technician stood outside a locked building at seven in the morning because a recurring visit had been expanded into absolute instants six weeks before the clocks went back. The three kinds of "when" that don't convert into each other, why a recurrence rule is not a list of timestamps, what Odoo hands you over the API, and how to test a bug that only reproduces twice a year.
A discontinued article disappeared from the catalogue for one colleague and stayed visible for the next, because the cache Vercel runs for you is a per-process detail the moment you self-host. What revalidateTag actually reaches, what a shared cache handler costs you in exchange, and why our own answer is still one replica.
A security questionnaire asks for a CSP, you copy the nonce recipe everyone publishes, and your statically generated site quietly becomes a dynamically rendered one. Which directives cost nothing, why the nonce is the expensive part, and how we split a policy so the security lands where it actually matters.
Raising the body-size limit is the fix that keeps working right up until it doesn't. Why buffering user files through your application is a dead end, the presigned handshake that replaces it, the checks that still have to happen after the bytes land, and why the ERP should be handed a pointer instead of a payload.
Sessions fell 41% the month after the relaunch and the leads went up, because the old site counted everybody and the new one only counts the people who said yes. What the consent rule actually covers, why cookieless is not automatically banner-free, the server-side denominator that makes the numbers honest again, and why the count that pays lives in the ERP.
The fix took forty minutes and a quarter of your users still hit the bug three weeks later, because a mobile release is a copy on somebody else's device. What over-the-air updates genuinely replace, the minimum-version gate you have to ship in v1 or never, why your API is permanently multi-version, and the autumn maintenance window nobody schedules.
The new site is faster and better looking, and three weeks later organic sessions are down a third. Nothing looks broken, because a 404 is a working page. Where the URL inventory actually comes from, why the sitemap isn't it, where redirects belong in a Next.js stack, and the rule that stops people blanket-redirecting a thousand URLs to the homepage.
Belgium's structured e-invoicing mandate landed on 1 January. Switching it on was an afternoon; everything it exposed was the quarter that followed. What Peppol actually addresses, why the failures live in your contact records rather than your ERP, what UBL refuses to carry, and why 'sent' stopped meaning 'delivered'.
