Are you just pointing Claude (or whatever) at an SSH connection, or are you having the LLM write config management code and then applying that? Or something else?04 Jan 2026 16:23 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3mbmdhsn7sc2mhttps://bsky.app/profile/jacobian.org/post/3m3pofocqis2wThe “default” working model for open source projects is working in public: you don’t need permission to contribute, you can just show up. When this doesn’t work, people often retreat into working in private. This is a mistake!

A short but important note for them: newcomers should generally ignore career advice from people who've been in the field longer than 10 or 15 years. https://jacobian.org/2025/mar/13/beware-advice-from-old-heads/13 Mar 2025 16:54 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3lkbkpzazsc2uhttps://bsky.app/profile/jacobian.org/post/3lgvjxs3p2222Worth reviewing: https://freedom.press/digisec/blog/sharing-sensitive-leaks-press/29 Jan 2025 17:53 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3lgvjxs3p2222https://bsky.app/profile/jacobian.org/post/3lgsz7mm46k2mPart six of my risk series is up — a final (long) sidebar to the introduction, coming back around the the concept of quantitative risk analysis and giving a more complete explanation of what I see as the pros and cons of that practice: https://jacobian.org/2025/jan/28/quantitative-risk-revisited/28 Jan 2025 17:47 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3lgsz7mm46k2mhttps://bsky.app/profile/jacobian.org/post/3lgqtbwtpfk2d> Lots of situations in life are like this, where there’s a loud way to accomplish very little and a quiet way to do some good. And far too often, we reward people for doing the loud ineffective thing. https://alexgaynor.net/2025/jan/27/stop-demanding-performance/27 Jan 2025 20:56 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3lgqtbwtpfk2dhttps://bsky.app/profile/jacobian.org/post/3lgqt43c6l22xI'd like to write a version of https://jacobian.org/2020/may/8/engineering-resume-accomplishments/, but tailored to management roles.

These two “mediums” aren’t at all the same! https://jacobian.org/2025/jan/17/two-flavors-of-medium-risk/17 Jan 2025 17:55 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3lfxeidrlj22jhttps://bsky.app/profile/jacobian.org/post/3lfusjjtdtk2bMost serious accidents aren't singular events, but instead are the result of a series of small, seemingly-inconsequential missteps. We call this the Swiss Cheese Model, and it's one of the most important concepts in risk management: https://jacobian.org/2025/jan/16/swiss-cheese-model/16 Jan 2025 17:28 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3lfusjjtdtk2bhttps://bsky.app/profile/jacobian.org/post/3lfsbychwvc2gContinuing my risk series with a short sidebar: we usually define Risk as the product of Likelihood and Impact, but some disciplines include a third factor, Exposure.

Went super smoothly; the charging infrastructure along I-5 is _noticeably_ better than even just a year ago. New stations with more plugs, no de-rated stations, all just super smooth.22 Dec 2024 15:57 +0000at://did:plc:txprlryrn37cpbj7betsorn4/app.bsky.feed.post/3ldvrs62s5k2j
