Part of the new design is that brokers and controllers can be run on separate JVMs.

Under 100 for radio and TNC, sure. See the NinoTNC http://tarpn.net/t/nino-tnc/n9600a/n9600a_info.html . For radios we use second-hand commercial radios that we reprogram for Ham use. However, coax and antenna

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. BBS is also a pretty common application.

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 custo

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 th

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 consta

Cheapest? A Chinese radio off Amazon, e.g., https://www.amazon.com/BaoFeng-UV-5R-Dual-Radio-Black/dp/B00... . This will allow you to tune in to local repeaters and listen. N.B., you cannot legally transmit without

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 th

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 exte

My guess would be that they went with C to make it easier to hook into existing data systems like MySQL or Redis.

It's a better experience when you're dealing with a complete file and not an in-progress transcode anyways. With a file you can seek and pause/resume. That's much, much harder with a stream (if at all possible). The othe

I got something similar working in Java by simply exec'ing ffmpeg and getting a handle on the stream. Not being able to seek kind of sucks, and Chromecast does not like infinite streams. However, I've seen that he Chromecast will

New releases of iOS usually go hand-in-hand with a new device. They design the OS to be optimal for the latest and greatest hardware, not so much the previous generations. As much as I like a good tinfoil hat theory, I'd say this is ju

Guava has a nice explanation: https://code.google.com/p/guava-libraries/wiki/UsingAndAvoid... . Essentially, it forces you to actively think about the "absent" case when programming.
