    1. whenever I want to use my tablet it's rarely charged there always wants lots of updates

    1. tried to test some AA batteries. is 1.3 good? the lights didn't light up. Are the batteries on the meter low?

    1. The biggest benefit may be from substantially increasing the amount of physical memory in a server: 2 socket Xeon systems can hold up to 3TB of RAM, but 24TB of Optane, and 4 socket systems support up to 12TB RAM, but 48TB Optane. This could be a huge boost for applications that need truly enormous quantities of memory.
    2. Unlike flash, which physically wears out due to the stress placed by erases, 3D XPoint writes are non-destructive. This gives the drives much greater endurance than NAND of a comparable density, with Intel saying that Optane SSDs can safely be written 30 times per day, compared to a typical 0.5-10 whole drive writes per day.
    3. 3D XPoint is a new kind of persistent solid state memory devised by Intel and Micron. Details on how the memory actually works remain scarce—it's generally believed to use some kind of change in resistance to record data—but its performance characteristics and technical capabilities make it appealing for a wide range of applications

    1. In addition to the improved performance, Big Sur is far more versatile and efficient than the off-the-shelf solutions in our previous generation. While many high-performance computing systems require special cooling and other unique infrastructure to operate, we have optimized these new servers for thermal and power efficiency, allowing us to operate them even in our own free-air cooled, Open Compute standard data centers.

      Facebook's Open Compute Project releases open-source hardware designs created with energy efficiency and ease of maintenance as priorities.

    1. Developing code for an FPGA is actually describing how the above pieces are configured and interconnected.

      Great way to describe this!

    1. lowRISC is producing fully open hardware systems. From the processor core to the development board, our goal is to create a completely open computing eco-system. Our open-source SoC (System-on-a-Chip) designs will be based on the 64-bit RISC-V instruction set architecture. Volume silicon manufacture is planned as is a low-cost development board. There are more details on our plans in these slides from a recent talk lowRISC is a not-for-profit organisation working closely with the University of Cambridge and the open-source community.

    1. Ronja is a free technology project for reliable optical data links with a current range of 1.4km and a communication speed of 10Mbps full duplex. Applications of this wireless networking device include backbone of free, public, and community networks, individual and corporate Internet connectivity, and also home and building security. High reliability and availability linking is possible in combination with WiFi devices. The Twibright Ronja datalink can network neighbouring houses with cross-street ethernet access, solve the last mile problem for ISP’s, or provide a link layer for fast neighbourhood mesh networks.
    1. RISC-V: free and open instruction set architecture (ISA). including "rocket chip" cpu reference implementation.
