I am not expecting to use the thing like an FTP server, but I do expect to be able to boot off it and store basic system stuff like a last-known-time since the thing lacks an RTC and time can't be acquired until after network init. I do not think it's appropriate to discount the Pis or any other SBC and a toy for children. Sure it's used that way but so are pencils, books, and anything else. Some things just don't require a full blown server and are served just fine by the pi. For example, I have an old venerable UPS and power distribution unit I have taken apart, serviced, and modified over the years. I can get data from it and control it via a custom driver shim for Nut Daemon. Now I want all the servers, routers, and switches in the rack to be aware of the UPS's state so that if the power is out past a certain battery threshold, various devices will start to power down so that only essentials are left. I also want to be able to programaticly energize each inverter inside the thing as more or less load is needed to help achieve maximum efficiency. No point in having both inverters active when at less than 40% load. I also want to record line conditions like input freq, voltage, etc for historical analysis on the monitoring server. The Pi is what I had laying around the seemed suitable for the task. It's got GPIO pins and a network port. Sure there are other SBCs I could have used but a lot of them are still going to have SD cards or some kind of write-limited flash storage for their rom. It's not as good as spending the time to actually write some firmware based on OpenWRT but for 30 dollars it's well worth it's weight. -- ______________________________________ / "We have the right to survive!" \ | | | "Not by killing others." | | | | -- Deela and Kirk, "Wink of An Eye", | \ stardate 5710.5 / -------------------------------------- \ \ /\ /\ //\\_//\\ ____ \_ _/ / / / * * \ /^^^] \_\O/_/ [ ] / \_ [ / \ \_ / / [ [ / \/ _/ _[ [ \ /_/ _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
