What Your Monitoring Costs the Database

Metadata queries are expensive because the server assembles the answer by walking itself. Measured on production with the backups excluded, the heaviest remaining reads were our own monitoring — the worst examined 1,748,148 rows to return two.

How to Find What Is Scanning Your Tables

Knowing a table is scanned tells you little; knowing which statement scans it tells you everything. Reading MySQL's statement digests closed three open cases at once — the heaviest readers were backups, and 91.4% of the examined-row volume on the server turned out to be dumps.

Sixty Percent of Your Reads Use No Index

A database either uses an index to find rows or scans the table, and on a small table the scan is the right choice. Measuring which is which on a production system: 90 million of 150 million row reads used no index, most of it fine, three tables not fine at all.

The Indexes Nobody Reads

Indexes accumulate because nothing ever removes them, and removing one means proving it is unused. MySQL will tell you: of 604 on a production database, 414 went unread in a day — though two thirds of those cannot be dropped anyway, and the rest turn out not to be costing what you would expect.

OpenAI Will Not Let You Self-Serve Its Enterprise Agent Product

Presence handles billing disputes, insurance claims and IT requests by voice and chat. Deployments are limited to eligible customers and delivered by OpenAI's own engineers and selected integrators, which says more than the feature list does.

Your Scheduler Has Never Reported a Failure

Fifty-nine thousand runs, forty-four commands, zero failures — because for background tasks the failure path ran in a process that could not find the row to update. Here is the fix, and whether it held.

Your Daily Report Is Counting the Wrong Day

A naive date filter and a timezone-aware one disagreed on twelve of twenty-one days, once reporting six items on a day that had none. The totals over the period differed by one, which is why nobody had noticed.

The Zimbra Patch Was Out For A Month Before Anyone Noticed It Being Exploited

CVE-2026-73570 gives an unauthenticated attacker shell commands as the zimbra user, but only where an optional SNMP package is installed and notifications are on. Version 10.1.20 shipped on 20 July. CERT Polska saw exploitation on 17 August.

How to Behave When You Are Rate Limited

Five clients, one job, one throttle. Hammering issued 553 requests to fetch 40 things and finished behind the client that read the reset timestamp and waited. Jitter lost both times it was measured, for a reason worth knowing.

What Your Rate Limit Actually Limits

A route limited to 30 a minute and one limited to 60 turned out to share a single counter, because the framework keys it on the domain and the address and not on the route. The effective limit is the smallest ceiling a client touches.
