    Degradation: Dell and Lenovo copy Apple without thinking
    • Dell XPS 13, all full size USB 3.0 ports eliminated, only USB-C left


      SD card reader has been replaced with a MicroSD card reader. Yep.

      Lenovo premium laptops - main innovation is plastic cover for webcam


      Fully eliminated Thinkpad power connector, now you are forced to use USB-C connector (that will break from any serious cable pull).

      Same elimination of all ports and SD readers.

    Degradation: NVidia effictively bans cheap render farms
    • Nvidia updated its GeForce and Titan software licensing in the past few days, adding a new clause that reads: “No Datacenter Deployment. The SOFTWARE is not licensed for datacenter deployment, except that blockchain processing in a datacenter is permitted.”

      Their words:

      GeForce and TITAN GPUs were never designed for data center deployments with the complex hardware, software, and thermal requirements for 24x7 operation, where there are often multi-stack racks. To clarify this, we recently added a provision to our GeForce-specific EULA to discourage potential misuse of our GeForce and TITAN products in demanding, large-scale enterprise environments.

      NVIDIA addresses these unique mechanical, physical, management, functional, reliability, and availability needs of servers with our Tesla products, which include a three-year warranty covering data center workloads, NVIDIA enterprise support, guaranteed continuity of supply and extended SKU life expectancy for data center components. This has been communicated to the market since the Tesla products were first released.

      Capitalism in its best.

      Company banning lot of cheaper and better cards using EULA agreement for drivers (sic!).

      But they offer you to use same cards for... blockchain (aka energy burning for crypto scam).

      And prostitute media like pink bunnies eating it for lunch without much complain.

    New patch for Intel processors can slow down PCs up to 30%
    • The bug allows everyday programs to "illegally" access certain contents in protected kernel memory. The "fix", so to speak, is to implement Kernel Page Table Isolation (PTI), which, for all intents and purposes, makes the kernel invisible to running processes. In a perfect world, such training wheels shouldn't be needed to isolate the kernel, but software patches that are nearing release for Windows, Linux and macOS systems will address the exploit head-on.

      Fixing this vulnerability in software also comes with a big hit on performance. Additional overhead is introduced to maintain a barrier between memory address spaces, which can result in a performance handicap of 30 percent or more. However, recent Intel processors with PCID (Process-Context Identifiers) enabled could have the performance impact lessened somewhat.

      Both Microsoft Azure and Amazon Web Services have scheduled maintenance that will take place over the next week, although there is no detailed explanation for the downtime.

      AMD processors aren't affected by the bug due to security protections that the company has in place.



      Note - FFmpeg here is joke with almost only CPU load.

      Biggest hit can happen with 4K and up raw projects and applications where big amount of data is moved from GPU and back.

      Most hit will be for old CPUs, surprise.

      Looks like planned thing to save industry after they hit the wall.

    Defective Pixels on Sensor Classification
    • Defect pixel is a generic term used to designate a pixel that does not behave like it should, but it is not a non-functioning or dead pixel. This short paper will list and explain the types of defects.

      • Dead pixels do not respond to light at all and they don't provide any information. They can be replaced using some interpolation but the lost information won't be retrieved. Dead pixels can be black, white (or let's say the maximum output value) or any intermediate value (also called stuck pixels).
      • Hot pixels respond do light normally but suffer from excessive dark current and can saturate at reasonable exposures even in the dark. Such pixels can only be used at short exposure time or at low operating temperatures.
      • RTS (Random Telegraph Signal) pixels respond to light and provide once in a while a sequence of correct values but they can randomly jump up and down with a well defined offset. Such pixels typically take two or three offset values but can have many more offset values. The time that the pixel spends in each offset state can be characterized but as the jumps are random in nature, they are very difficult to correct. However, advanced algorithms can fully retrieve the information from such pixels.
      • Wide variance noise pixels have in average the right response to light but their noise is much larger than for the other pixels. The information can be retrieved using time averages.
      • Blinking pixels can be either dead blinking if they jump randomly between two dead states or blinking operating if they jump between the right value and a dead state.
      • Clipping pixels behave normally up to a certain value (resp. from a certain value) where they will clip. They are only usable below (resp. above) their clipping value. The pixels that start at a too high value sometimes only have excessive offset.

    Capitalism: Wealthiest people became $1 trillion richer
    • Citing its Billionaires Index, Bloomberg reported Wednesday that the world’s 500 wealthiest people became almost $1 trillion richer ― that’s $1,000,000,000,000 ― in 2017, thanks largely to booming stock markets. For comparison, that’s over four times as much wealth as they gained last year.

      Amazon founder Jeff Bezos, the world’s richest person, saw the biggest gain in wealth in 2017. He added $34.2 billion to his net worth, which now totals $100 billion.

      Mark Zuckerberg, founder of Facebook, and Bernard Arnault, CEO of luxury goods company LVMH, also saw significant increases to their wealth this year. Zuckerberg, ranked by Bloomberg as the fifth richest person on Earth, added about $23 billion to his fortune. Arnault, ranked sixth, saw a $24.5 billion boost.

      As of Tuesday, the 500 billionaires on Bloomberg’s wealthy index had a total net worth of $5.3 trillion ― up from $4.4 trillion in 2016. This year’s total is more than the gross domestic product of Japan or Germany, or that of the U.K. and France combined

    Diffraction Limit and quantum imaging
    • image

      Quantum imaging exploits the spatial correlations between photons to image object features with a higher resolution than a corresponding classical light source could achieve. Using a quantum correlated N-photon state, the method of optical centroid measurement (OCM) was shown to exhibit a resolution enhancement by improving the classical Rayleigh limit by a factor of 1/N. In this work, the theory of OCM is formulated within the framework of an imaging formalism and is implemented in an exemplary experiment by means of a conventional entangled photon pair source. The expected resolution enhancement of a factor of two is demonstrated. The here presented experiment allows for single-shot operation without scanning or iteration to reproduce the object in the image plane. Thereby, photon detection is performed with a newly developed integrated time-resolving detector array. Multi-photon interference effects responsible for the observed resolution enhancement are discussed and possible alternative implementation possibilities for higher photon number are proposed.
