One of the things I've learned over the past eight years of fractional CSO work is that the judgment call work is useless or impossible without enough time maintaining your working context of the system. The judgement time doesn't provide nearly enough context to perform well without supplemental time, and that knowledge goes stale surprisingly quickly. The real product of a software team is a group of people who understand the system deeply.

Razor 1911 made a PC demo for Revision 2026 that's a whirlwind retrospective of the group, touching on a lot of warez/art/demoscene tech, tools, and history since they started in 1985. It won the PC Demo category and clearly earned it. https://www.youtube.com/watch?v=2AnbYNudAyM

Can someone explain why people liked Claude Code over Cursor? I can't wait to get back to Cursor as it's faster, goes off track less often, needs lees baby sitting and has smarter defaults. #cursor #claude

📰 When headlines fixate on “zero-days,” they distract from the real question: What is the manufacturer doing to prevent recurring classes of coding error? 🤔

Drama focuses on the Villains. Accountability focuses on how the Vendors make the product.

Remember, when something in the news upsets you, you are *not obligated* to spend the next hour hunched over your phone reading live updates and social media hot takes.

You *can* stay informed without succumbing to this urge -- an urge deliberately conditioned into us for decades by the 24-hour news cycle and exploitative for-profit social media.

Step away from your screens, let your psyche absorb the blow, and read about it in a newspaper tomorrow morning if you like. You have permission!

Quick questions for all my security peeps who say to investigate all the open source software you use...

I'm installing Jupyter notebook to do some scientific computing tasks. What tools do I use to do that investigation? How long should I take to do the investigations, and is that a per package time or an across the packages time?

Just for context, here's what pip installed:
