Itβs an arrangement that allows Metro to avoid soliciting public comment on the surveillance technology, which critics worry…

The question is simple: "I want to wash my car. The car wash is 50 meters away. Should I walk or drive?" Obviously, you need to drive. The car needs to be at the car wash. The question has been making the rounds online as a simple logic test, the kind any human gets instantly, but most…

Design @ Hadrius Like many other fields in tech, how design teams operate is shifting dramatically. That means Figma is being used less and less, while agents are being used more and more. Counter-intuitively though, this means that designers with hard-skills (light coding, speed, design craft) are needed more than ever. At Hadrius, weβre leaning into this: Design is integrated into the codebase, with engineers The feedback loop…

Today the Web and Internet is owned and controlled by large for profit corporations and a few governments. Corporate ownership combined with government policies has left us as tenant and product. It has given us a surveillance economy and enshittification. What if I do not wish to be tenant and product? What can I do to change the equation? Those two questions lead me to a bigger question. What happens when ownership and…

While this can be done manually, i automated the process using the Python libraries BeautifulSoup and Selenium-Python (you can also use the Requests library in this case, but I already had Selenium imported lol). Hereβs some pseudo-code to give you an idea of how it was done:…

**What Youβll Learn**: ...a purely symbolic gesture... This project began with an attempt to write the fastest lisp interpreter I could in under 1000 lines of C. It snowballed from there as I kept trying to see if I could add powerful features with minimal code. At the same time I assembled a library of some of my favorite C code (by myself and others) to use as a base for a standard library. This includes ios, a replacement for parts of C's stdio that adds more…
