Americans have had it so good for so long they don't understand reality. Maybe we need to walk down that road to recall how bad it is.

Likely. The coils only job is to ignite the lamp by whacking it with high voltage to strip some barium elections off the coil to induce plasma and therefore electrical flow. The plasma then excites the phosphorus to make light. After that the coils could just be stubs of wire so long as current keeps flowing through the excited plasma. If you did it inductively it would achieve the same means but I don't think the plasma would be as dense so the lamp not as bright. My theory anyways.

Wild to see this posted. I worked for the guy that invented this at Sylvania, I have a bunch of photos of the early prototypes. They never figured out how to commercialize it and in the process of trying to manufacturer it in China the manufacturer stole the IP and started making them under their own brand and stole the market. They were called Icetron lamps. I worked in their R&D facilities and domestic manufacturing sites in the early 2000s.

I love this community, I used to rant about efficiency all the the time on reddits self hosting community and everyone thought I was insane. If the damn thing is going to run 24/7 for 5+ years then put a little thought into its power usage!

I personally love old Dell optiplex micros on eBay. Cheap, plentiful laptop hardware in a cute little box which allows modest upgrades. My primary server in a full sized case is just a laptop CPU, Ryzen 5600g. It brings me joy that my network has four servers and still is under 75w idle for everything including networking gear.

Should do, yep, but obviously not well if dudes getting PR for doing it privately.

I was thinking more along the lines of "oh hey you're building a water park, cool! By law it must be handicap accessible so please make a section easily accessible and here is a $1mil grant to make that possible, show us your plans before we issue the permit". This feels fairy reasonable.

Its uplifiting but shouldn't we value these things as a society and fund it accordingly? I hear we are a rich nation. Instead we depend on the charity of some rich guy who wanted to take care of his own daughter.

+the fact the pi is so darn cheap, has the IO and can emulate the game on the system not at all designed specifically for the task while also running a whole Linux stack and being online. Things have advanced tremendously.

My wife won't leave the house without several water containers as it she is crossing the god damn Sahara. We live in the North East, its not even dry! I always ask her how she survied childhood without stupid fancy bottles that are marketed. Fortunately she is patient with my crap and loves me...

No gpio but old centrino laptops make excellent low power servers. My primary server was a first gen centrino from 2011 up until recently and I think it only used 12w idle after putting a SSD in there. Had it's own UPS built in.

I was being dramatic, sorry, yes, this!

You would be the bad guy if you make him return it. Personally I would have a talk with your son about how unusual the act is and how his act could be used as leverage over him, nothing is free. Teach him healthy skepticism. Also call back those parents and tell them to fuck off, completly unacceptable they bought something connected and important for your son without checking with you first. They dont know your house or rules...

Edit: the phone isn't on friends family plan, right?

So I had a verbal conversation with a coworker yesterday and now I'm getting fed very specific ads. No possible way it's accidental. I have most of the microphone access to apps limited, I have Google assistant turned off and no VPA setup in my home. I use a Oneplus 9 pro, does anyone have recommendations on how to further root cause this or just par for the course for using any standard android OS? Have other folks had similar experience after locking down their stock phones?

 

Title says most of it. Spin electric scooters exited the Seattle market and abandoned their scooters all over the city and apparently they have a pi 4 in them!

 

Found some tiny coffee plants while in Hawaii and thought they looked amusingly fake so I grabbed a picture.

 

I call this nonsense host ‘Ghost’, for me it’s similar to a tape backup solution. Fairly simple concept, it’s an old Pi1 + external mechanical drive that sits dormant with its ethernet off. Once a month, at a random time and random date it enables the ethernet, spins up the drive and pulls data from the main server to update its drive then goes black until next month. The only way to check or maintain the pi is a push button that toggles the ethernet interface. I slapped it together with some scrap wood, spare hardware and screwed it to a 2x4 in a dark corner of my basement. It’s my 5th string backup, the ultimate insurance policy because I’m mental.
