"People are all doing a thing, and I think there are mistakes they could make with it" to me is a challenge to think about how to better scaffold those people rather than a reason to have contempt for people.

OK, not that anyone asked, but let me just explain why my takes re: Tesla stans are what they are and why they're so pointed. I ended up in conversation with someone who is a pretty big deal in Tesla circles. Had influence with Elon etc. He didn't know the words "Alpitronic Hypercharger" 🧵

Hey if you’re looking to try/retry/find a home on the ActivityPub/mastodon shaped part of the fediverse, I will personally help you get set up, move followers, block assholes, etc I have no interest in debating the merit of bsky-v-mastodon, purely offering help. Reskeets welcome ✨

People who are having success managing (low-stakes, non-production) servers with LLMs — how are you going about it? 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?

The “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! There is a middle ground: jacobian.org/2025/oct/18/...

Working in Between Public and Private - Jacob Kaplan-Moss

If working in public isn’t working, consider adopting a middle-ground option instead of retreating into fully-private.

Reading @jacobian.org 's exit from tech rings a bell. We love computers but we hate the tech industry. We love space but we dread the space industry. We love music but we loathe the record industry. We can have nice things, just not under capitalism. (OTOH, excited for him ❤️)

Changing Directions - Jacob Kaplan-Moss

<p>I have two important announcements:</p> <ol> <li> <p>I&rsquo;m leaving the tech industry. Hopefully &ldquo;for good&rdquo;; if not, at least &ldquo;for now&rdquo;.</p> </li> <li> <p>As such, the co...

In case anyone’s wondering, `jacobian . bsky . social` isn’t me. Super flattered that I now rank high enough to score an impersonator tho!

A lot of tech people, particularly more junior folks, are looking for jobs right now. 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. jacobian.org/2025/mar/13/...

Beware tech career advice from old heads - Jacob Kaplan-Moss

If you’re new to tech – say, less than 5 years in the field – you should take career advice from people who’ve been in the industry more than 10-15 years with enormous skepticism.

A reminder: doing illegal things is illegal. If somebody gives you an order to do something illegal, it is your obligation to say no. "Just following orders" has never been a defense, legally or ethically.

Part 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: jacobian.org/2025/jan/28/...

Sidebar #4: Quantitative Risk Revisited - Jacob Kaplan-Moss

In part 1 of this series, I briefly covered quantitive risk measuring – assigning a numeric value to risk, like “$3,500”, rather than a qualitative label like “medium” – only to quickly recommend agai...

I'd like to write a version of jacobian.org/2020/may/8/e..., but tailored to management roles. If you have a manager resume that lists specific accomplishments, and you'd be OK with me anonymized bits in a post like that, please email me your resume? jacob at jacobian dot org.

What accomplishments sound like on software engineering resumes - Jacob Kaplan-Moss

Effective resumes need to contain two things: responsibilities and accomplishments. The first tells the read what your job was; the second, what your results were. Unfortunately, most people fail at t...

Part whatever in my risk series: When you look at a likelihood/impact risk matrix, you might notice that “medium” appears twice – once as high-likelihood/low-impact, and once as low-likelihood/high-impact. These two “mediums” aren’t at all the same! jacobian.org/2025/jan/17/...

Sidebar #3: Two Flavors of Medium Risk - Jacob Kaplan-Moss

When you look at a likelihood/impact risk matrix, you might notice that “medium” appears twice – once as high-likelihood/low-impact, and once as low-likelihood/high-impact. These two “mediums” aren’t ...

Most 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: jacobian.org/2025/jan/16/...

Sidebar #2: The Swiss Cheese Model - Jacob Kaplan-Moss

In the real world, accidents happen when a series of small missteps align to create severe consequences. This is something we call the “Swiss Cheese Model”: imagining a systems failure as a set of “ho...

I am a former incarcerated firefighter. I served in a California fire camp from 2009 to 2012. Misinformation is afire on the internet, so here are facts about the prison firefighter program, all in one place. A thread.

I was on the board of a nonprofit that received funding from MacKenzie Scott. Her no strings attached gift was game changing. More philanthropists need to adopt this model instead of capitalist brained ideas of efficiency that are ultimately counterproductive.

Evan Sutton@evansutton.bsky.social · 2y ago

Ah yes, I see it's the time of year when the Philanthropy Industrial Complex (Big P for short) seeds negative stories about Mackenzie Scott because everything about the way she gives money undercuts their entire model... fortune.com/article/mack...
