What's stopping you from starting today?
Lack of motivation to work on more technical stuff after having done the same all day at work? Mental exhaustion? Wanting to spend the remaining free time with loved ones instead?
Sorry for this naive question, but isn't every network card build out of discrete logic components?
Discrete is the opposite of integrated, as in integrated circuit. In practice, it means using multiple components. In a strict sense it means no integrated circuits at all, I suppose. But it's also a relative thing. So while a 7400 series chip is not a "discrete" component as most would think of it, using a hundred 7400 series chips to implement a processor is relatively more discrete than a microprocessor. (It's cer…
The software required to run a TCP/IP stack was also large, limiting the system to a handful of active sockets, and consuming large parts of the available CPU power to run something like Telnet or FTP.
It took a few years for CPUs to get more powerful, more RAM to become affordable, and for network hardware to become integrated onto the smaller boards like ISA or NuBus.

While I do agree this may apply somewhat to the original topic, your dig at suburbanites seems like a mischaracterization. I would expect most other folks are primarily worried about being murdered during the event. With the murder rate in America near historic lows, I think the person you're replying to is spot-on. It's a lot of hysteria fueled by social media, foreign actors, and the fact that security paranoia is…
These statistics do not help anyone create a reasonable personal risk assessment. Murder is at an all time low! But my sister in law is a drug addict, and last year she got mad so her boyfriend shot and killed a family member right in their nice suburban foyer. There's more to it than that.
Most people worrying about home invasions arent thinking about it being their niece.
But reading (https://qdiv.dev/posts/eth-to-spi/) about somebody that made that chip from basic components is really awesome.
Thanks a lot !

Being worried about a hardware backdoor in your network card is more about technology fetishism than realistic threat analysis. It's like suburbanites being worried about home invasion. Sure, it's technically possible to happen, but the concern reflects personal neuroses rather than practical considerations. There's a disconnected, individual grandiosity in both cases - "what I have is so valuable that other people w…
You are minimising [0,1]. (I also think you are wrong in your risk asessment) [0] https://www.berkeleywellbeing.com/minimizing.html [1] https://en.wikipedia.org/wiki/Minimisation_(psychology)
So this is for an all-custom computer, which is rather more impressive on its own (to say nothing of "So I made a C compiler."), but now I'm curious what the minimal implementation of an ethernet card for a "normal" PC would be. I suspect a lot of it would be very similar, up to that you could do checksums on the PC's CPU (probably just baked into the driver). It'd need to be attached - either bare serial or more use…
If a normal PC had an ISA bus (like they did 30 years ago), my network card could have been connected to it with just some minor modifications.
