I'm part of a TARPN and the main thing we do is chat. There is a simple chat program that runs on the network so we can do realtime multi-user chat. It's pretty fun.
I think it's something like 30W over a single ethernet cable. I'm running a few devices with PoE that are not network enabled, just conveniently located near an ethernet cable that's not near a power outlet.
Packet radio has made some progress since the 80s :). Here in North Carolina we have a network called TARPN http://tarpn.net/t/packet_radio_networking.html. We use re-purposed commercial radios, RaspberryPis, and custom TNCs for 1200 baud packet links. Some folks are experimenting with higher speed links (9600).
These ISM modules will work on low power for close range links, but you can't just slap an amplifier and call it a day. There are regulatory issues with the tech they use (spread spectrum, wide bandwidth, encryption, etc).
Ordered a RPi Zero W from Adafruit on a Saturday, got it on a Wednesday. Took about two hours to get through a headless install of Raspbian [1], most of which was fighting with my Mac's Disk Utility.
Not knocking the BASIC Engine, I think it's cool as heck, just pointing out that getting started on RPi is not really as painful as it once was. You can even purchase an SD card preloaded with Raspbian!
I would guess they have injectors for the filling at the centers of those cells. A Voronoi edge is equidistant from the two points it bisects, so it kind of makes sense that this would happen naturally if the filling is injected at a constant rate.
After getting licensed, you'll probably get frustrated with the UV-5R and look into a more capable hand held unit, or a mobile radio. These start at around $150 and go up from there (plus antennas, power supplies, etc).
Was this done using the DVDs? I'm curious about any potential licensing issues with the screen caps and subtitles. Did you have to get permission/sign something - or does this fall under fair use?
I'm skeptical how a small form factor oven like this could provide even heating that is required for many kinds of baking, even if it has convection fans. Also, having such a small volume means that most of the heat will escape when the door opens making it difficult to get that crucial "oven spring" for bread baking.
It seems like a perfectly acceptable (albeit pricy) alternative to a toaster over, however.
Lucene has had this capability for a while now. A regexp query (as defined by the RegExp class) is compiled into an automaton for quick comparison with the inverted index, also represented as an automaton. Automatons and FSTs are used extensively by Lucene these days. Out of curiosity, I did some playing around with Lucene's RegExp class when it first came out (or rather, when I first learned about it). It provides a really interesting way to build regular expressions: https://gist.github.com/mumrah/6104234
Neat! I made one of these in Java a while back after reading the snowflake Twitter post (which has since been removed). Looks like Twitter has retired Snowflake: https://github.com/twitter/snowflake
