96-Core NanoPi Fire3 Boards Cluster is a DIY Portable Solution to Teach or Develop Distributed Software

96-Core NanoPi Fire3 Cluster

Nick Smith has been messing around with clusters made of Arm boards for several years starting with Raspberry Pi boards, including a 5-node RPI 3 cluster, before moving to other boards like Orange Pi 2E, Pine A64+, or NanoPC-T3. His latest design is based on twelve NanoPi Fire3 boards with 8 cores each, bringing the total number of cores to 96.  The platform may not be really useful for actual HPC applications due to limited power and memory, but can still be relied upon for education and development, especially it’s easily portable. Nick also made some interesting points and discoveries. It’s pretty with shiny blinking LEDs, and what looks like proper cooling, and the cluster can deliver 60,000 MFLOPS with Linpack which places it in the top 250 faster computers in the world! That’s provided we travel back in time to year 2000 through 🙂 By today’s standard, it would be rather slow, but that’s an interesting historical fact. Nick …

Holo P2P Distributed Hosting is Powered by Holochain Technology, Leverages Holo Fuel Cryptocurrency (Crowdfunding)

The Internet is now mostly centralized, for example most people search with Google, and Facebook dominates the social media space in many countries. That also means access to content can easily be blocked by governments, and many companies will use your personal data to their benefits. Holo network promises to “take back the Internet” thanks to a P2P distributed web hosting system, where people hosts app from developers in their HoloPort devices, and get paid for hosting crypto apps in Holo Fuel cryptocurrency that can in turn be used to pay for processing power and/or storage on the network, or converted into other cryptocurrencies like Bitcoin, or fiat money (Dollars, Euros…). It’s like a new Internet that uses the current “pipes” (i.e. you’d still need Internet through your ISP), but all content would have to be created from the ground up. It basically aims to replace datacenters, websites, and app from larger companies. The first prototype crypto apps include Clutter …

Colorful C.J1900A-BTX Plus V20 Bay Trail Motherboard Takes 8 Graphics Cards for Cryptocurrency Mining

Intel Bay Trail processors are mostly found in tablets, 2-in-1 hybrid laptops, and mini PCs, and they’ve often give placed to Cherry Trail processors, and in some cases Apollo Lake ones. x86 compatibility, low cost and low power are the main selling points of the Bay Trail processor family. Colorful has found a different use case, as they designed a motherboard with 9 PCIe x16 slots, one for a card powered by an Intel Celeron J1900 processor, and 8 to add graphics card in order to mine cryptocurrencies. The blue PCI slot takes a PCI CPU card with an the following specifications: SoC –  Intel BayTrail J1900 quad core processor @ up to 2.42 GHz with 2M Cache, integrated Intel HD graphics; 10W TDP Memory – 1×DDR3L SO-DIMM, DDR3L 1333MHz/1066MHz Storage – 1x mSATA slot, 1x SATA 3.0 connector, 1x 4-pin SATA connector Video Output – HDMI Connectivity – Dual Gigabit Ethernet via RTL8111E USB – 2x USB 2.0 ports …

OpenDime is a Bitcoin USB Stick based on Microchip SAMD21 MCU, and ATECC508A Security Chip

The first time I heard about crypto currencies, specifically Bitcoin, was probably around 2011, and later in May 2012, I noticed a “micro-payments with Bitcoin digital currency” talk at a Barcamp. I did not think much of it at the time, but with hindsights, I should definitely have started to mine some Bitcoins considering the price was $5. Nevertheless, cryptocurrencies appear to be here to stay, and while most transactions occurs over the Internet, Opendime project has made a hardware USB dongle to store Bitcoins, and earlier this year, announced version 2 of their “Verified Bitcoin Credit Stick”. Hardware specifications of OpenDime v2.0 / v2.1 USB stick: MCU – Microchip / Atmel SAMD21 Cortex M0 MCU Security Chip – Microchip / Atmel ATECC508A Crypto chip with support for SHA-256, TRNG, and public key signing (ECDSA) USB 2.0 interface to connect to a computer Bitcoin seal The USB stick works like a piggy bank, you can add Bitcoins to it changing …
