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.

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.

Cloudflare Built A Browser That Throws Away Everything Humans Need

Kitesurf runs in V8 isolates on Workers with no Chromium underneath, claims 3 to 7 times less CPU and memory for agent tasks, and passes over 215,000 web platform tests. It has no tabs, no extensions and no pixel-perfect rendering, on purpose.

How to Write an MCP Server Without a Framework

MCP is JSON-RPC over a pipe. Sixty-two lines of dependency-free code, driven directly with the protocol — the handshake, a tool call, the three ways it says no, and the two things it must ignore. Written against revision 2025-06-18, which the July 2026 revision has since superseded.

What Happens When You Click Install in ComfyUI

ComfyUI Manager offers to install the missing nodes, you click, and a log scrolls past too fast to read. What runs in those few seconds is a git clone, a pip install from a file you have not opened, and sometimes a script the author wrote.

How Old Is the Code You Installed?

The median package in this site's tree was published 286 days ago — but one in five has seen no release in two years, and the oldest is 11.2 years old. Age is a question, not a verdict: a finished utility is not an abandoned one.

What Our Own Site Sends, and Why We Can't Tell You Exactly

We tried to measure our own monthly egress with root on the machine. Three sources gave three answers, and extrapolating the most precise one produced 97% of the entire server's traffic — a figure that disproves itself.

AI-Generated Code Security Has Not Improved in a Year

Veracode tested more than a hundred models and found a 56 per cent security pass rate, flat year on year. Coding-specialised models were no safer than general-purpose ones, scale barely helped, and only reasoning moved the number - by five points.
