From the last officially revised list. 18.5/30, plus 2 bonus points.
1. Set up a Raspberry Pi, Arduino or other single board computer.
2. Crimped / punched down an ethernet plug or jack.
3. Know at least one programming language. Does BASIC (and really basic BASIC at that) count?
4. Own a custom domain name. Sort of...
6. Used a multimeter and soldering iron. Half a point. I'm quite capable of butchering things with a soldering iron...
7. Rooted/jailbroken/flashed custom firmware on to some device (bonus points if you've broken that device in the process but managed to recover it).
9. Been asked by a family member to fix something technological (bonus points if you've later been accused of causing other, entirely unrelated, technological issues by helping out that one time).
10. Member of Geekzone.
14. Consciously used open source software.
16. Read Dune, Foundation, and the Hobbit + Lord of the Rings (potentially fraught trinity there). I'll claim a partial credit here for Dune - I've read the first Dune many times, and a couple of years ago re-read it along with the next three books in the series. Gave up at Chapterhouse Dune though.
17. Watched the Matrix, Star Wars, Star Trek and Doctor Who (again, potentially fraught [strike]trinity[/strike] quarternity). I'll offer more bonus points for (a) knowing the Machete Order and (b) not really having a clue what the Matrix Sequels were about. Have seen all the above (most of them many times over). I'll claim the bonus points for knowing the Machete Order (and have watched in said order), and not really knowing what the sequels were about (though have had plenty of conversations/arguments about them)
19. Built your own PC.
20. Have something IOT in your house.
21. Worn a t-shirt or hoodie displaying a computer games, cience-fiction character, comic book character, maths problem, or anything else that can properly be described as "geek chic".
24. Own/made/resurrected some kind of retro technology, purely for nostalgia reasons. I have a working A500, which I'm hoping will last long enough to be able to show my kids when they're old enough to care.
26. Participated in a hackathon. Sort of. I won a "non-technical" hackathon at work last year, but hope to participate in a real one this year.
27. Have something 3D printed in your home or office (or perhaps have a practical need for something 3D printed in your home). I used Sketchup and the 3D printers at the library to reproduce a broken plastic part from an outdoor table.
28. Have a figurine/model/poster of a beloved pop culture icon from your childhood within sight of your computer desk. I have 3D metal sculptures of the Millenium Falcon and a TIE fighter (made from a kit) duelling at the front of my desk. I also have a James Bond Trivial Pursuit game set up for visitors to ask me questions when they visit.
29. Visited a geek mecca while on holiday (bonus points if your family members or travel companions rolled their eyes when you insisted that you go. Double bonus points if a family member/travel companion fall asleep from boredom while inside that geek mecca. <Cough> Mrs MDF <cough>). Bletchley Park in 2012. Awesome.
