    Well said. Anarchism has received horrible press at the hands of Big Democracy but many of our current problems are rooted in the concentration of power, money and influence that capitalist societies seem to produce. On the other hand, can we live without the many products and technology that require large scale effort? It feels like that would be a major challenge for any fledgling anarchic society.












  • My 99 Corolla ran fine until 100k when I noticed excessive oil consumption. Over a period of months it became slightly underpowered and then dramatically lost power at high speed when cylinder three was permanently misfiring. Huge cloud of smoke indicated failed piston rings which explained the oil consumption during previous months. Apparently a relatively common problem. I wonder if this would foul the O2 sensor and cause the MIL to trigger eventually?



  • I’m probably in the same boat as you, I have zero formal CS education. The way I originally learned was various: by embarking on small projects, fixing broken computers so I could play games, reading books, watching videos. The key thing in learning any subject is to recognise that when you don’t understand something it’s usually because some foundational knowledge is missing. You cannot properly understand a computer file system before you grasp the concept of binary numbers, bits and bytes, for instance.

    Lately I’ve been using Chatgpt. You can ask it to write code in any language. Ask it to solve a particular problem and then start dismantling the answer, step by step. When you don’t understand the answer, ask it to elaborate. For your purposes, you could ask it to script a port scanner on your home network. This is key skill for any aspiring hacker and if you can get that working on your LAN, those principles can be adapted to WAN. Get a copy of the CIA vault 7 library, ask chatgpt to explain snippets of the code. I would imagine you have to preface your questions as coming from a ‘white hat’ perspective or it may balk.


  • A basic grounding in computer science would be a good starting place.

    Do you know the difference between the various processor architectures and operating systems? Do you know the difference between real time computers and interrupt based systems? Are you familiar with the seven layer network model and which layers the different services interact with the hardware and application software? Are you grounded in cryptography and the system of public and private keys, modulo operations, prime number factorisation?

    This is assuming that you already understand coding and are proficient in at least one language. None of these skills and knowledge on their own are indispensable or completely necessary but these things are what computers are made of, how they communicate and how they are secured.
