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!

Oh neat! Related, I’ve often wished for some sort of Gantt charts that can show uncertainty, but I don’t have good enough designer/dataviz chops to really know what that would look like.

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.

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...

> 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.

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...

400 individual members of the Django Software Foundation – pretty cool milestone! https://thib.me/400-django-individual-members Now going for 500! 🌈 That’d be a great milestone to reach for the 20-year birthday of #Django in July 2025. Submit a nomination, or 2, or 3 to help make it happen?
400 individual members of the Django Software Foundation
As of a few weeks ago, the Django Software Foundation reached 400 individual members.

Funny, in infosec we do “event” vs “incident”. “Incident” triggers regulatory/contractual obligations, so we call things an “event” until we’re sure it’s a real incident and not a false alarm.

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!

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:

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...

Continuing 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. What's up with that?

Sidebar #1: "Exposure" - Jacob Kaplan-Moss
Risk is usually defined as the product of two factors: Likelihood and Impact. However, some disciplines include a third factor: Exposure. What’s that about, and when is it useful?

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.

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.
