I can recommend Teeworlds (CTF modes) for casual office gaming. I've organized a tournament once and got my ass kicked in the final matches (2v2 CTF) as people improved really quickly.
Recently it switched to running via Proton if you had Steam Play enabled (and broke completely for me). Solution is/was to disable Steam Play and it will use native version.
Typically they get paid the initial listing sum of the auction (at least) and what happens on secondary market is not their concern, similar to classic art pieces.
Royalties can be a thing provided NFTs are traded using a smart contract that pays royalties to the creator but it's not that common since artists are compensated well enough by the first approach and don't need to milk secondary market trades.
You can build it for way lower than that - in their BoM they use quite expensive distributors like Misumi - if you only source your steppers from other places that's already hundreds saved. If you buy the laser tube and power supply from China it's few thousands shaved off (the only problem is the risky shipping of fragile laser tube).
Because Cardano is what ETH might have been if done right. They did a tons of (actually scientific) research on the topics mentioned in this article but the author won't mention Cardano as it is his direct competition (even nicknamed Ethereum killer).
It doesn't feel slow to me (compared to for example C++ compilation) and you can iterate quickly using cabal repl (:r) or ghcid[1] which both support partial recompilation of changed files.
LinuxCNC (at least Axis) can be controlled by keyboard - F1 is especially handy to stop the job in progress if anything goes wrong. Arrow keys can be used for jogging, with shift it uses max travel speeds but dedicated CNC pendant for jogging is on my TODO list as well as standalone DRO with 7 segment displays.
Multi-planet battles while cool looking and fun are not balanced and most of the competitive matches are played with no orbital tech on single planet - these are quite similar to competitive matches in TotalA and really well balanced. If you play ladder or with people looking for competitive matches then it feels a lot more like old RTSes although you can still zoom out or send units in not so obvious ways (frontal attacks rarely work) which often makes for interesting surprises and strategies.
It takes a bit to get used to playing on planets instead of classic maps with borders but that’s what makes this game special.
It doesn't maintain any state - NixOps uses SQLite database which makes it cumbersome to share with other devs.
Morph can't create machines for you - it doesn't have any backends except for SSH. It means fewer dependencies but you need to create targets manually or with something like Terraform. I've only used 'libvirt' and 'none' backends with NixOps and even wrote a 'dumb' backend that unlike 'none' backend wouldn't generate and store SSH keys in state but respects .ssh/config.
One feature of morph is really nice - declarative health checks that are run after the deployment automatically or can be triggered manually.
I also find it easier to explain to not-that-technical people as it basically requires one or two commands.
We're trying something similar - to provide a set of curated services with example deployments for cities or municipalities. We build on NixOS and use morph for deployment. Services include simple-nixos-mailserver, Redmine, Sympa, owncloud with LibreOffice Online and many more. If you're working on something similar or your're interested in helping with this cause feel free to contact me via email or IRC.
GoPro cameras run RTOS and one of the threads run Linux which is cold booted only once (or during an update) and stored for next fast hot boots - it was only used for providing WiFi and streaming functionality.
It contained IPFS url with a login form sending data to some hacked site so this is already a standard practice.
It is also a bit amusing when you host your own mailserver for years.
