Even I can'ts stay serious at all times. Looks like my halo is slipping here. Some fun with Ada's neo pixel LED strip, an uno, and a fat old comptuer supply.

Nothing special, just a test of a new pi-cam on part of the west part of my front yard. I can now watch the burn box without roasting myself! And see weather rolling in when I adjust the cam brightness so the sky doesn't wash out - something you can't do with many cameras.

It’s really just a matter of time; the working man’s deal with his overseers is half dead already. But there’s still inertia in the system, and even the losers are keeping the faith. Hope dies slowly, after all. Nonetheless, the deal is collapsing and a new wave of robots will kill it altogether. Unless the overseers can pull back on technology – very fast and very hard – the deal that held through all our lifetimes will unwind.

Both look like education issues to me.  Can stupid be fixed? /rhetorical

Another day, another 12kwh or so in the battery bank for my off-grid solar system.  It'll be nice to have a little more, especially at this time of year... the other stuff in this compartment of the "energy shed" is because it used to have a 6.5 hp engine and the generator from a P-51 Mustang in it.  I don't use that any more, so we removed it and put the new batteries in there instead.  Yes, I kept the generator, it's a nice piece of history that served me well for decades.  It can also be a really powerful DC motor, should I ever get around to retrofitting my go kart.

Brexit = Death of the Technocrats

My political opinions lean more and more to Anarchy (philosophically understood, meaning abolition of control not whiskered men with bombs) … the most improper job of any man, even saints (who at any rate were at least unwilling to take it on), is bossing other men. Not one in a million is fit for it, and least of all those who seek the opportunity.

Is it too soon to say "Fuck YEAH!"?
Have no idea about our bureaucrats, but the basic US citizen is with you all the way. Leaving "the empire" worked out well for us for at least a century before we lost our way again.

Hey +Doug Coulter this is wonderful news, I had become very unhopeful that we'd vote in favor of independence and I have been surprised. Now I am so excited the opportunities for UK in the world are immense, not just for our own prosperity but also for countries all arpund the world. The EU blocked our investment in a new Nuclear reactor a Hinkley, forcing us to accept a French / Chinese owned plant that would sell us power at twice the current rate, and has blocked us from funding the JET fusion torus in Oxfordshire, we can change that now, thats only one of so many #UKopportunity

Thought I'd share today's code, which works on linux on raspberry pi, odroid, or PC (defaults to odroid now, but simple to change).
http://www.coultersmithing.com/forums/viewtopic.php?f=33&p=5773#p5773 I'm using this as part of the remote control and data aq for my fusion reactor work. Since most good science is more "eh, that's funny" than "eureka", I thought I'd send and record as much as possible during a run.

A test of some of the new stuff I'm putting together for running my fusion reactor remotely with data acquisition.  Here I have 3 Raspberry Pi's live streaming video to an Intel NUC as part of that system.  All 3 pis, the Ethernet switch, and fiber converter (for isolation) are running off a common supply - death to wall warts and excess power strips!  It seems 3 instances of firefox use less ram than 3 of chrome, which is why I'm using that here, as I want all the videos visible at the same time, not in tabs.  Not bad - I plan a faster machine for my real op position, but it seems this Haswell NUC would do it - the rest of the data aq is lines of numbers at around 10 hz, going into a mysql database (on fusorpi) replicated to the op position (here).  The real op position machine has 4 displays, unlike the two shown here - there will be plots of the parameters in real time too.

The cams are remote and on their own machines (raspberry pi's), which stream to my operating position, far from the reactor, which is dangerous to be near when operating. Instead of 3 browser instances, I'm now using Vivaldi and tab stacks. This is a bit over 3 mbyte/second, far worse than hangouts, but then I'm also recording in > HD resolution while monitoring at low rez, and stuffing a database in real time with other data.

I liked the older versions of hangouts better, it used less BW than the current WebRTC, which seems to assume you actually have a real computer, not a crap phone. Real-time multi-way vid chats aren't exactly trivial to pull off, at least this old guy for whom the video phone was about as futuristic as a flying car for most of his life - at least we have vidchats, but hey, it's a lotta bits and a lot of cpu use for compression. (I know this having developed some of the math myself). The relatively weak CPUs on portable devices combined with the error rates, collisions and retries on wireless make it that much harder...those things aren't magic! Nothing comes close to a good old high power use CPU hardwired to the 'net. Never will - as phones get better, so will the big 'ol boxen.

The so-called "epic historic" snow in Floyd, VA on Jan 22, 2016. Not that epic...actually, it is more severe than it looks here - shortly after starting the timelapse, it turned to tiny ice particles that actually packed down the existing snow. Timelapse started at 7:30 AM, stopped at 6pm, 1 fpm shot, 24fps movie. This is a demo for you Mint users, more here: http://www.coultersmithing.com/forums/viewtopic.php?f=23&p=5728#p5728 Normally done with ffmpeg, but Ubuntu 14.04 and Mint don't support that - this is how it's done without it. Raspberry pi took the stills, about 3 megabytes each.

BTW I-97 joins I-90 North of Yakima and they received almost 72 inches within 7 days in the foothills and are still digging out as it comes down over and over in Leavenworth.

In the dim hope that hilarious mockery is more effective at producing useful change than angry words and acts...Long but worth it, my sides still hurt.   I couldn't have done better, and frankly, can hardly conceive of the possibility.
We apologize, but 2015 had so many negatives that we’re having trouble seeing the positives. It’s like we’re on the Titanic, and it’s tilting at an 85-degree angle with its propellers way up in the air, and we’re dangling over the cold Atlantic trying to tell ourselves: “At least there’s no waiting for the shuffleboard courts!” Are we saying that 2015 was the worst year ever? Are we saying it was worse than, for example, 1347, the year when the B...

As the Chinese curse says... It's been an interesting time with who knows what for the next to follow. Personally Nancy and I are getting the hell out of where we are for better pastures.
