    Capitalism: Marketplaces - new monopolies
    • In 2015 year online sales of marketplaces (Alixpress, Amazon, ebay, etc) from total online sales had been:

      • 35% in UK
      • 41% in USA
      • 63% in China
      • 69% in India

      Marketplaces also tend to slowly destroy small sellers except niche markets and replace them with medium and large (or their own sales as Amazon).

    Lab: Optical Low Pass Filters in Cameras
    • It turns out that the OLPFs in DSLRs are not really Gaussian, but something much simpler: beam splitters. A slice of Lithium Niobate crystal, cut at a specific angle, presents a different index of refraction depending on the polarization of the incident light. Let us assume that a beam of horizontally polarized light passes through straight, for the sake of the argument. Vertically polarized light, on the other hand, refracts (bends) as it enters the crystal, effectively taking a longer path through the crystal. As the vertically polarized light leaves the crystal, it refracts again to form a beam parallel to the horizontally polarized beam, but displaced sideways by a distance dependent on the thickness of the crystal.

      Using a single layer of Lithium Niobate crystal, you can split a single beam into two parallel beams separated by a distance d, which is typically chosen to match the pixel pitch of the sensor. Since this happens for all beams, the image leaving the OLPF is the sum (average) of the incoming image and a shifted version of itself, translated by exactly one pixel pitch.

      If you stack two of of these filters, with the second one rotated through 90 degrees, you effectively split a beam into four, forming a square with sides equal to the pixel pitch (but often slightly less than the pitch, to improve resolution). A circular polariser is usually inserted between the two Lithium Niobate layers to "reset" the polarisation of the light before it enters the second Niobate layer.

    Capitalism: How it works, episode 2
    • See episode 1 at http://www.personal-view.com/talks/discussion/15867/zaxcom-and-why-patents-must-go-to-hell-with-capitalism-as-company/p1

      Law is the will of the ruling class transformed into legal regulations.

      So, we continue to expose how laws are used in capitalism.

      Fluke story

      Sparkfun started sourcing a really great high-quality $15 multimeter back in 2008. This price-point enables countless beginners to get their feet wet in electronics. Fast forward six years and many thousands of multimeters sold. On March 7th, we were notified by the Department of Homeland Security/US Customs and Border Protection that our latest shipment of 2,000 multimeters was being inspected.

      This is to advise you that the following articles have been excluded from entry into the United States pursuant to US International Trade Commission Exclusion Order 337-TA-588. 337-TA-588 is formally titled: “Certain Digital Multimeters, and Products with Multimeter Functionality.” This is 162 pages of companies that have been brought under scrutiny by the US International Trade Commission because these companies were selling digital multimeters and products with multimeter functionality that have a contrasting color combination of a dark-colored body or face and a contrasting yellow border, frame, molding, overlay, holster or perimeter. Fluke filed for a trademark in 2000 and received it in late 2003. Fluke’s trademark number is 2796480.

      Sparkfun ultimeters are actually kind of orange, not Fluke yellow. The document from the Department of Homeland Security is matter of fact. Where is no opportunity for recourse or appeals process.

      They had two options, ship them back or have them destroyed. Having them destroyed costs $150 per hour with no indication of how much time it will take to destroy 2,000 units. Returning them has been ruled out by the manufacturer in China because the import taxes in China are steep.

      So, perfect example of capitalism in action. Where specific capitalists push their interests using power of whole ruling class above interests of society. Demand to destroy perfect good products, just because they can. Minor market players also suffer, but it is competition, someone always wins. :-)

      What Fluke wrote in regard to this? Check it out

      Like any organization that designs and manufactures electronics, we actively work to stop lookalike products from making it to the marketplace. We do this to protect our company and the jobs of our employees. We also do so because it is a matter of safety for our customers (really?).

      I mention this because we firmly believe that we must be – and will continue to be – vigilant in protecting Fluke and our customers. One step in doing that was registering a trademark protecting the look and feel of our devices so our customers know that if it looks like a Fluke it’s a Fluke (they are illiterate, as you protect color scheme?).

      It’s important to know that once we’ve filed for and received trademark protection, US Customs has the responsibility to determine what to stop at the border, or what to seize.

      and final part is just hilarious

      Earlier today we contacted SparkFun and offered to provide a shipment of genuine Fluke equipment, free of charge for them to sell on their site or donate. The value of the equipment exceeds the value of the Customs-held shipment. SparkFun can resell the Fluke gear, recouping the cost of their impounded shipment, or donate it into the Maker community.

      What have values, donations or such have to do with this? Yes, it can act as good PR move, but damage caused to society have nothing to do with it.

      Do not worry, European firms are also not better. They really like to file for design protections after patents expired. But this is for 3rd episode.

    Capitalism: DRAM prices
    • PC DRAM growing 30% q-o-q in Q4 and expected to grow another 40% in Q1.

      It is always consumer who pays for banquet.
