Tech Notes

Tech Notes: October 2020

My notes on information technology, technology, science and other matters, as taken from various podcasts, videos and other online flotsam.

Most days I go running. Podcasts and video lectures pass the time. To goose my dawdling mind, I try to remember *one* useful bit of information from each presentation. I Tweet this micro-epiphany in order to properly understand the idea, in 280 characters or less.

So, 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: eBPF makes the Linux kernel programmable; feature flags can speed development; Darwin's "Origin of Species" as technical writing; RSA vs. DSA for SSH; the challenges of spacing Web pages; share communications, not memory.
