| Dear Reader, In our podcast this week, Shane Hastie speaks to Michael Lopp, VP of Engineering at Slack, about intentional culture and continuous delivery. Aleksey Shipilëv, performance and OpenJDK developer at RedHat, has filed a new JEP draft to create a no-op garbage collector; that is, a GC that doesn't actually reclaim memory. Abraham Marín Pérez writes “This collector is aimed at aiding JVM implementers and researchers and, to a lesser extent but perhaps more interesting for the public, ultra-performant applications that generate little to no garbage. EAP18 of JetBrains' Rider features the return of .NET Core debugging support for Windows platforms. The previous preview of Rider saw this support removed in order to comply with the licensing terms of a subcomponent. An otherwise small release, EAP18 is crucial for .NET Core developers. Microsoft has released version 2.2 of the TypeScript language, which focuses on a new object type and improved developer productivity. Node.js 7.6 has shipped with official support for async/await enabled by default and better performance on low-memory devices. According to Chris Lattner, Swift creator and Swift team lead before moving to Tesla, defining a Rust/Cyclone-inspired memory ownership model is one of the main goals for Swift 4. Now that Swift 4 has entered its phase 2, the Swift team has published a manifesto detailing how Swift memory ownership could work. Google recently announced TensorFlow version 1.0. The Python API is now stable and experimental APIs for Java and Go have been added. XLA, the new domain-specific compiler delivers 7.3x performance increase in 8 GPUs setup and 58x for 64 GPUs for Inception-v3 neural network model. At the recent World Government Summit, Hexayurt Capital and ConsenSys released a paper called “Building the Hyperconnected Future on Blockchains”. The purpose of the paper was to provide an Internet of Agreements (IoA) strategy for the next wave of innovation in order to drive Globalization 2.0. Amazon has blamed the outage of its S3 web service, which took down many different sites, services and devices across the internet, on a typo. |
