This holiday season, why not give the gift of ultimate cosmic destruction?? 💥🌌 www.astrokatie.com/book Kirkus Reviews calls it “a delightfully unsettling narrative”! @leebillings.bsky.social raves about my “infectious enthusiasm for communicating the finer points of cosmological doom”!

Keynote at #EverythingOpen #eo2016 is Kylie McDevitt talking about IoT security standards and how devices are evaluated. It’s not hard to avoid poor practices. You can watch this conference online for a small fee, btw, see 2026.everythingopen.au

Just got back from #everythingopen (formerly linux.conf.au). Legit was asked a dozen times "is DevOps still a thing" in response to me trying to explain my métier as a systems engineer. Only reply I could think of was to use your notion of feedback between developers and the systems they develop.

Really enjoying opening keynote at #everythingopen from @kyliemcdevitt.bsky.social about experiences determining patterns in device security [weaknesses]. What's interesting is although she's using IoT analysis examples, this explicitly all applies to the compute infrastructure we build, too #eo2026

the levels are illustrated with tachometer-style indicators that are colour-coded using standard green (good) -> yellow (medium) -> red (bad) colour scheme correlating with the ppm measured in each room

the raw ppm value for each room is also visible in the middle of its respective “tachometer”

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.
