    Automation is shifting repetitive, uncreative, brutish work to repetitive, uncreative, brutish machines, thus freeing humans to pursue nobler interests.

    LOL mostly "uncreative, brutish work" just not so much repetitive. And especially "un/underemployed" which is no badge of nobility.

    No consolation to the workers who can't find new jobs, I know. But for the larger society, the benefits outweigh the costs.

    Let them eat cake. Until the revolution, anyway. If there's one lesson of the 1900s, if the czars were smart enough to issue food stamps, they'd still be in charge.

    The best part about firefox sync is it always resulted in duplicates duplicates so even if you "lost" one set of bookmarks bookmarks then you'd have the other copy copy right there. That's why I stopped using firefox sync. xmarks on FF actually worked flawlessly, but FF wanted to put them out of business by shipping something built in that claimed to do the same thing for free but actually didn't work at all. Then I switched to chrome and never looked back. GOOG can F up quite a few more times until they reach the same level of annoyance FF sync reached for me.

  3. Re:UDP ... on Linux 3.7 Released · · Score: 4, Interesting

    I forgot to mention one real life situation where UDP over TCP does not work.. UDP conceptually works pretty well with real time live streaming. "Here's 5 seconds of audio of the ball game". 5 seconds later, if lost, that packet is meaningless, don't bother re-sending it, the RX will just output 5 secs of silence or whatever. TCP does not understand that at all, so you can get serious problems with live streaming if you try to stick that inside TCP and experience significant network congestion. Buffers get bigger until they pop, "live" becomes randomly "tape delayed" based on recipient... Also TCP doesn't understand variable bit rate, so its ideas about buffer allocation bear little resemblance to what the codec actually wants to do.

  4. Re:UDP ... on Linux 3.7 Released · · Score: 5, Interesting

    Why does vxlan transfer L2 packets using UDP and not TCP? I have also seen this on other L2 protocols like L2TP and PPTP ... just curious ...

    TCP has a feedback loop when packets are lost... So you'd have that at both layers, the actual session and the tunnel.

    Its an engineering thing where if you embed a feedback loop inside a feedback loop, things will be OK if you're VERY careful but most are not and you'll make a lovely oscillator and just blow it all to bits.

    Fundamentally, UDP doesn't guarantee delivery so its OK to shove it inside UDP, and TCP has its own repair mechanism so you don't need to guarantee its sub-layers, so its not like you're missing anything.

    Finally it just kills performance because TCP loves big buffers for each connection so you need megatons of ram until you start dropping packets and letting TCP police itself. Which meanwhile results in horrific latency. But if you tunnel over UDP, you don't really need much of a buffer on the tunneler itself and you'll overall end up with better latency specs. So its cheaper and works better. Hard to beat that combo...

    I wonder how they compared radiation/glass speed through air?

    Roughly freshman 2nd semester physics lab, compare the thickness of a glass lens to its focal length to figure the glasses index of refraction, which is just a weird way of expressing how much slower light travels in the glass.

    We also did an interferometer lab with a sealed clear tube where the air was sucked out by a vacuum pump and then using monochromatic light you'd count fringes moving as air leaked in a needle valve. Simple gear, but fancy enough to measure how much air slows down light. This will be the next step, evacuated waveguide instead of aerial RF.

    In the world of "high tech" you just buy a $50K TDR and a $150K OTDR and measure how long (long as in time) certain cables and stuff are.

    Cheapie method involves a long piece of cable (or fiber, or mirrors, or...) looping around a really fast inverter and see what frequency it oscillates at. Lets see, an 80 meter wavelength is about 4 MHz so 40 meters of cable would resonate as a halfwave around 4 MHz or so, right? Or you play games with resonators.

    There's about a zillion ways to do it.

    So what would be your solution

    Let it run its course and burn itself out. It'll be replaced. Between SOX costs and other related costs, and HFT, both the corps and the retail investors are not using capital markets as much as they used to. This is not theoretical, look at NYSE volume over the years. Zerohedge has a freakout about it every time yet another record low volume is set.

    Now its important to realize in the "short" term we're nearing a market peak to be followed by a pretty big decline. Markets melting up where prices go high and volume collapses are a typical symptom of this part of the cycle. So you need to factor that out. I'm talking about trends longer than one business cycle.

    Evidence shows individual retail investors are pretty much done with the market, the corps are fed up with the regulation costs. Both the buyers and sellers are abandoning ship... The big long term picture over the next decade or two is probably growth in private equity and what were known as "junk bonds" 30 years ago. Junk bonds are actually a pretty good idea, although I'm sure some goofball can figure out a way to expensively regulate them and HFT them.

    Have no clue what line-of-site is

    I started in the telecom biz in the waning twilight years of microwave relay stations, and frankly "line-of-site" is pretty accurate, at least in that era. You look on the map and there's a line of digital microwave relay tower sites.

    I'm sure in the boom years Manhattan island was criss-crossed by a spaghetti bowl of reflector paths, but in the end years of the tech it was mostly semi-dedicated runs in basically straight lines across rural countryside, from ridgetop to ridgetop, to connect the middle of nowhere with what we call civilization. The tech was a good match for the job, in that remote sites didn't need much bandwidth (how big of a call center can a lumbermill and some hunting cabins require?) so 3 T3 is plenty, and rural workers (lumberjacks etc) could mostly understand "Stay 100 feet away from the microwave tower or your nuts will fry off" (actually we only used a couple watts, so, uh, no, but scaring them worked pretty well at keeping them away) but they could never understand when they were ripping down trees and yanking out stumps to leave our fiber alone.

    The biggest problem was salespeople always lie, its their job of course, so engineering got endless complaints from "fiber" customers who noticed their "fiber" lines were impaired whenever it was foggy or intense t-storms. The funniest was when they found out and demand we bury fiber for them. For free, of course. Oh and can we have it done by the end of the day, so I can tell my boss its permanently fixed. Um yeah someone from sales will get back to you on that.
