Sergey Chechaev·3 days agoBuild Selenoid image for Apple Silicon (M1)First, we need to prepare the environment Then we need to build a basic image Building basic image will take some time ~ 20 min Build Selenoid image for Chrome Files for building image: GitHub link. I’m uncertain if this is necessary, but it’s probably better that the version of Сhromium and ChromeDriver will be match. Therefore, we look at the repository page with Сhromium: Chromium Beta branch. …Selenoid2 min read
Patrik Zelena·May 10Setup Istio on AWS EKS with ARM nodes using AWS CDKIstio is the de facto service mesh for Kubernetes. To leverage istio, an istiod control plane and the envoy side-cars must be configured. Fortunately, istio provides us with various ways to easily install and configure the mesh. AWS EKS is a managed Kubernetes service that makes it easy for you…Aws Eks5 min read
Erik EngheiminITNEXT·May 4RISC vs CISC Microprocessor Philosophy in 2022A new look at the RISC vs CISC debate by framing it as a debate on how to spend a limited transistor budget to achieve performance. — PEOPLE LIKE to think about the distinction between RISC and CISC processors as being about some specific set of features or some magical limit on number of instructions or transistors. Few Instructions Doesn’t Mean RISC Let us get some very obvious misconceptions out of the way. Because RISC stands for Reduced Instruction Set Computer, there…Risc15 min read

John Koetsier·Apr 13This stamp-sized 3-core ARM computer could make trillions of things smarterDoesn’t need a battery. Harvests energy from radio waves. Connects to the world with a no-code integration platform. Should be pennies each “soon.” We have billions of smart things. How can we create a true internet of things with trillions? We won’t … unless we have a super-cheap, super-small, super-efficient chip that doesn’t need a battery, has significant sensors and capability, and can be printed almost for free.Io T2 min read

Erik EngheiminCodeX·Mar 20Addressing Criticism of RISC-V MicroprocessorsIs RISC-V just a rehash of 1980s RISC ideas? Requires too many instructions to do simple stuff? — RISC-V is an instruction-set architecture (ISA) for microprocessors which people seem to either love or hate. In particular there seem to bit of rivalry between the ARM and RISC-V camp developing. It is perhaps not without reason. RISC-V and ARM represent quite radically different philosophies about how a RISC chip…Risc V16 min read
