    Good book: Just Ride
    • image

      There’s an old cliché that “racing improves the breed,” and it’s been said about bikes for as long as I can remember, and was old the first time I heard it. It makes non-racers seem subservient, passively waiting for godlike racers to give thumbs-ups to new bike technologies, as though nobody else is qualified to evaluate it; and that’s why I don’t like it. That, and it’s not true anymore.

    Google dream is closer, DRM standard for HTML5 approved
    • Director reached a decision that the EME specification should move to W3C Recommendation. The Encrypted Media Extensions specification remains a better alternative for users than other platforms, including for reasons of security, privacy, and accessibility, by taking advantage of the Web platform. While additional work in some areas may be beneficial for the future of the Web Platform, it remains appropriate for the W3C to make the EME specification a W3C Recommendation. Formal publication of the W3C Recommendation will happen at a later date.

      And first place where it will start to be used will be youtube. I am pretty sure that soon all video content will be non downloadable and encrypted.
      But also advertisements will some become core part of DRM protected bundle, so you will be forced to watch them full, 100% of the time.

    Capitalism: On marketing role
    • As you must know, everything in capitalism is focused on sale. Most important moment is to sell at maximum profit.

      image

      Suppose you make tire for road based slow rolling product. Ideal tire tread is simple flat one, as it provide maximum traction and maximum flat protection.
      Also for slow moving things you can't have aquaplaning, and it is sole normal reason you see grooves on auto tires.
      You can open any good article on F1 tires, very refreshing.
      Yet more "advanced" tread sell better, as it looks... well, advanced. Plus for some manufacturers it allows to save on rubber also.
      Better guys like Schwalbe compensate marketing requirements by smart design and added puncture protection.

    Olymus dust removal sytem work
    • What you see here is rare, actual, slow-motion footage of a prototype Supersonic Wave Filter (SSWF) dust reduction system being tested a year or so before the debut of the Olympus E-1 DSLR camera in 2003. Each OM-D is equipped with a much more advanced SSWF dust reduction system, which vibrates over 30,000 times per second to remove dust particles from the image sensor every time you turn the camera on. But realizing this system wasn’t so easy.

      By applying a conductive coating to the glass protecting the sensor, Olympus engineers were able to remove dust that stuck to the sensor by static electricity. Being able to remove the dust adhered to the sensor by intermolecular forces was a much larger challenge, and for this the Supersonic Wave Filter was invented.

      However, the first SSWF only generated around 100g of acceleration, and the dust didn’t even budge. Many rounds of trial and error were carried out, and Olympus engineers utilized resonance to amplify the vibrations so that an acceleration of thousands of g was achieved. Still, not all dust fell from the sensor. Only the dust located at the vibration crests fell, and the dust located at the nodes of the vibrations stayed put. Finally, the engineers managed to generate the vibrations so they peaked uniformly across the sensor, removing all dust particles.

      The SSWF dust reduction system has since been providing Olympus interchangeable lens camera users with clean, crisp images, receiving various accolades and high praise around the world.
