I had heard about that project before and was wondering how he managed to emulate USB devices on linux to a host system. TIL about the Linux Gadget framework: http://www.linux-usb.org/gadget/

Heh. I am George Hilliard V (that is, my dad is IV and my son is VI). So it makes a certain amount of sense!
Wow you have a son and are able to do these things? That’s impressive. I can barely do work and family already. Well done
The post should be tagged "2019" (@dang?) - I have noticeably less free time these days :)

#34I have some business cards that are so valuable, I can't give them away. I was attending a conference with some vendor booths, and while it wasn't anything like a job fair, I thought I'd try my luck at pitching myself as a prospective hire. So I went to the most IT-oriented vendor that I could find, introduced myself, and proudly presented my solid plastic CompTIA A+ certification. The good fellow thanked me and prom…
It's not necessarily why they didn't reach out, but waiving certifications and other random credentials (e.g. completion of some Coursera course) is usually not the best strategy to get hired.
Talking about concrete work you've done (of interest to the company) is much more convincing.

#35Author here! Trivia: I really, really wanted it to run Doom, so that I could have a section titled "But Does It Run Doom?". This is challenging with no screen; SDL has an experimental ASCII backend where in theory you could draw terminal graphics over SSH. But it refused to cross compile despite repeated efforts. So, sadly it does not in fact run Doom.
More of a suggestion for a future design, but how about using DOOM's software rendering over X forwarding (potentially over SSH)? You'd need to have the card present itself as a network interface, which would add to the complexity and cost however.
What's the highest baud rate the serial interface supports? You could theoretically get PPP over serial working, but I suspect at best you could only manage a few frames per second. 320x200x4bpp at 1fps requires a 256k baud rate minimum, and that's just streaming the video, without any overhead—I suppose you could apply compression: ssh -C with the "none" cipher; or just compress each frame as a PNG, but I'm thinking outloud—this would probably involve writing your own renderer.

#36This was a novel idea once. But nowadays I would stay away from plugging in a usb device of someone I just met.
This is from a professional embedded systems engineer who is presumably only giving these to prospective clients because, obviously, they’re more expensive than regular business cards.
If you can’t bring yourself to connect a USB device from your embedded systems engineer then you shouldn’t be working with that person. You’re also going to have a difficult time working with them on just about any product.
Maybe just appreciate this for what it is: A novel business card.

I am not familiar with the rules for names like this. If you don't mind me asking, how does it work? Are your first male descendants expected to be named the same until one of them changes his mind?
Yes exactly. I was free to name him whatever I liked, but at this point it's too neat to break the tradition.
Another question from a country where only the king does this: Is it part of your legal name, or just a convention?
(Also, does it make your feel like royalty?)

With the USB gadget Driver in Linux you can have the existing USB Hardware enumerate as a USB Ethernet adapter without too much config work so that would not add much to the BoM :)

#39Look at that subtle circuit, the tasteful thickness of it... Oh my god, it even has a nano ARM!

On the other hand, there's no shortage of (dumb) employers that insist on various certifications.
