Marc Andreessen is wrong about introspection

https://www.joanwestenberg.com/content/images/size/w1000/2026/03/karl-raymund-catabas-6yFGUCyLgMI-unsplash--1--1.jpg
Marc Andreessen claims introspection is a modern pathology invented by Freud, but this is historically inaccurate and ignores the long history of self-examination in philosophy. His thin theory of human flourishing prioritizes external action over inner life, which is essential for understanding what makes a life worth living.

SSH certificates: the better SSH experience

SSH certificates provide a better and more seamless SSH experience by eliminating the need for Trust on First Use (TOFU) and allowing for short-lived keys, forced-commands, and automated key management. An SSH CA can be used to sign host keys and user keys, making it easier to manage SSH connections and eliminating the need for manual key deployment and TOFU.

What Category Theory Teaches Us About DataFrames

The author analyzes the structure of dataframes and identifies three fundamental operations: Delta (restructuring), Sigma (merging), and Pi (pairing), which can be used to build a dataframe algebra. Category theory provides a framework for understanding these operations and their relationships, allowing for a more principled design of dataframe libraries.

We present a detailed engineering analysis of the fastest physically plausible disassembly of Mercury into Dyson swarm components, using known physical principles and aggressive extrapolation of present-day materials and manufacturing. Beginning with a 1,000-tonne self-replicating industrial seed, the system grows through approximately 58 doublings. The revised central result is that a purely ...

Category Theory Illustrated – Types

https://abuseofnotation.github.io/category-theory-illustrated/06_type/zfc_pairing.svg
Type theory is a mathematical theory that is an alternative to set theory and category theory, and it is used to define collections of objects that are interesting without accidentally defining collections that lead to paradoxes. Type theory is based on the idea that the interesting collections are the source and target of functions, and it is used to define types and functions in a way that ...

What we learned building 100 API integrations with OpenCode

https://cdn.sanity.io/images/7yse5usn/development/5e8336ac7c1f9f743b75831e768cf359f3ed7e9b-1904x2062.png
Developers built an autonomous agent that generates API integrations across five platforms in 15 minutes and under $20, using skills and a simple orchestrator. The agent learned from its mistakes and was improved with better instructions, tighter edit permissions, and explicit checks to produce trustworthy integrations.

Build your own Dial-up ISP with a Raspberry Pi

https://www.jeffgeerling.com/blog/2026/build-your-own-dial-up-isp-with-a-raspberry-pi/pi-isp-ibook-hero.jpeg
Last year my aunt let me add her original Tangerine iBook G3 clamshell to my collection of old Macs1. It came with an AirPort card—a $99 add-on Apple made that ushered in the Wi-Fi era. The iBook G3 was the first consumer laptop with built-in Wi-Fi antennas, and by far the cheapest way to get a computer onto an 802.11 wireless network. I go into more of the history of Apple's AirPort and ...

Good ideas do not need lots of lies in order to gain public acceptance (2008)

The author learned from business school that good ideas don't need lies to gain acceptance and that dishonest forecasters are worthless. This principle helped the author predict the Iraq War's failure due to false claims about WMDs and the importance of audit to prevent such errors.
