Well, it is appropriate as a business card for an embedded systems engineers, not so much for a system security one! More seriously, I never managed to understand the "obsession" with ROHS (this here is just an example): >I made sure to have a lead-free process—the boards, parts, and solder paste are all RoHS—so that I wouldn't feel bad about giving them to people. I mean, you are creating something that (besides bei…

I don't get this lead-free hatred on internet forums. People say they can't solder with lead-free, and that it is terrible, and that joints look dull. So much hatred that I actually tried it out. And I found the process is basically just the same and there is nothing to be afraid of. Just set the solder iron temperature a bit higher and that's it. Works like a charm.

Bismuth is used as a replacement for lead, if you want lower temperature solder. 58Bi/42Sn alloy is cheap and about as good as Pb/Sn, but is more susceptible to thermal fatigue. I used 57Bi/42Sn/1Ag to solder heatpipes. Works great!

Perhaps you could do something like this, incorporating the jack into the PCB instead of an elevated component? https://upload.wikimedia.org/wikipedia/commons/d/df/XJACK_ne...

I never understood why Apple and other thin laptop manufacturers didn't do this? I remember X-Jacks fondly, and would love to have a super-thin laptop with ethernet.

Some ultrabooks have ethernet sockets that fold out. In my experience the reliability is ... mixed.

I mainly work in web-dev, but working in embedded systems is kind of my hobby. It's kind of refreshing working on bare-metal, optimizing up-to single bytes of data, when I'm usually working on layers and layers of abstraction everyday.

Where does a web-dev turn to to get started in this as a hobby?

Check out nand2tetris !

Maybe I'm twisted but my first thought if that if I were a pen tester I would want business cards exactly like this. And yes, they would run Linux... and some other things. :-)

Ha someone on Reddit suggested this. See the thing is, they have my contact info printed on them, so I'm really easy for the police to find after everything is hacked!

Your real contact info?? :)

Start with an Arduino and the Adafruit tutorials. Very gentle learning curve. https://learn.adafruit.com/category/learn-arduino From there, can decide where your interests might be. To continue with Arduino hardware but without the IDE, I'd recommend _AVR Programming_ https://www.oreilly.com/library/view/make-avr-programming/97... For other low level programming, Atmel's AVR Studio and their dev boards are incredible…

Very helpful, thank you!

What an absurd tragedy. Everyone was just fine with usb-A and ethernet ports and hdmi but no, now these laptops need dongles for literally everything.

Absurd tragedy? Maybe for you. For me, it's been a good life since the 2016 MacBook Pro. I got a decent dock, and connect everything with a single cable.

I would assume you paid a good $150 for one, given that the others either don’t supply enough power or can’t do 4K@60.

Author here. It's a really good conversation starter. I've given a couple of them out and the reaction is always that I bought it somewhere, and I have to explain that no, I really did the entire design from start to finish!

Really loved the look of your website... Is it designed by you?

It is nice! Congrats on your career/YC. I really liked "The art of being Disagreeable" because I've found that to be quite accurate in my experience.
