My notes on information technology, technology, science and other matters, as taken from various podcasts, videos and other online flotsam. In effect, this page is a log of everything I've learned over these past 30 days, as summarized on Twitter. Some of this material I go on to use in my day job, as managing editor for The New Stack.

This month: Goodhart's Law and the difficulty of measuring performance; Rocky Linux picks up where CentOS left off; a data-aware shell; Jupyter Notebooks for SRE post-mortems; Optimization is at odds with efficiency; Configuration-as-code > Infrastructure-as-Code; the service mesh-as-security kernel; sudo's security woes; the revolution of movable type; and the costs of toxic masculinity.
