  • Microsoft set to close licensing loopholes, leave cloud rivals high and dry

    Microsoft this fall will begin closing loopholes in its licensing rules that have let customers bring their own licenses for Windows, Windows Server, SQL Server and other software to rival cloud providers like Google and Amazon.

    The Redmond, Wash. company laid down the new law in an Aug. 1 announcement, the same day it previewed Azure Dedicated Host, a new service that runs Windows virtual machines (VMs) on dedicated, single-tenant physical servers.

  • Schedule for Open Infrastructure Shanghai now released

    It may feel like summer is still in full swing, but before you know it, we’ll be facing those shorter days that autumn (or fall, depending on your geographic location and/or linguistic preference) brings. To brighten up these shorter days, many in the open source community will be looking forward to the Open Infrastructure Summit (sometimes shortened to OIS) in Shanghai. The first of these summits to be held in mainland China, this is an exciting event as it will bring together some of the finest minds in open source from around the world in one location.

  • What is Edge [and Fog] Computing and How is it Redefining the Data Center?

    Some of you may have noticed that a hot new buzzword is circulating the Internet: Edge Computing. Truth be told, this is probably a buzzword you should be paying attention to. It is creating enough of a hype for the Linux Foundation to define edge computing and its associated concepts in an Open Glossary of Edge Computing. So, what is edge computing? And how does it redefine the way in which we process data? In order to answer this, we may need to take a step backwards and explain the problem edge computing solves.
    We all have heard of this Cloud. In its most general terms, cloud computing enables companies, service providers and individuals to provision the appropriate amount of computing resources dynamically (compute nodes, block or object storage and so on) for their needs. These application services are accessed over a network—and not necessarily a public network. Three distinct types of cloud deployments exist: public, private and a hybrid of both.

    The public cloud differentiates itself from the private cloud in that the private cloud typically is deployed in the data center and under the proprietary network using its cloud computing technologies—that is, it is developed for and maintained by the organization it serves. Resources for a private cloud deployment are acquired via normal hardware purchasing means and through traditional hardware sales channels. This is not the case for the public cloud. Resources for the public cloud are provisioned dynamically to its user as requested and may be offered under a pay-per-usage model or for free (e.g. AWS, Azure, et al). As the name implies, the hybrid model allows for seamless access and transitioning between both public and private (or on-premise) deployments, all managed under a single framework.

  • An introduction to Hyperledger Fabric

    One of the biggest projects in the blockchain industry, Hyperledger, is comprised of a set of open source tools and subprojects. It's a global collaboration hosted by The Linux Foundation and includes leaders in different sectors who are aiming to build a robust, business-driven blockchain framework.

    There are three main types of blockchain networks: public blockchains, consortiums or federated blockchains, and private blockchains. Hyperledger is a blockchain framework that aims to help companies build private or consortium permissioned blockchain networks where multiple organizations can share the control and permission to operate a node within the network.

Programming Leftovers

  • Ned Batchelder: Scriv

    I’ve written a tool for managing changelog files, called scriv. It focuses on a simple workflow, but with lots of flexibility. I’ve long felt that it’s enormously beneficial for engineers to write about what they do, not only so that other people can understand it, but to help the engineers themselves understand it. Writing about a thing gives you another perspective on it, your own code included.

  • Dirk Eddelbuettel: RcppSpdlog 0.0.2: New upstream, awesome new stopwatch

    Following up on the initial RcppSpdlog 0.0.1 release earlier this week, we are pumped to announce release 0.0.2. It contains upstream version 1.8.0 for spdlog which utilizes (among other things) a new feature in the embedded fmt library, namely completely automated formatting of high resolution time stamps which allows for gems like this (taken from this file in the package and edited down for brevity)...

  • [Perl] Week #078: Leader Element & Left Rotation

    First thing first, I managed to do video session for both tasks this week. It is so satisfying when everything goes as per the plan. For the last couple of weeks, I could only do one video session. One day, I would like to video with PIP. At the moment, I am little uncomfortable showing my face in the video. There is another reason why I can’t do it now. I don’t have my personal office in the house. I have been working from home since mid-March, nearly 6 months, sitting on sofa, 9-5. I must confess it is not easy. I miss my office chair and noise-free environment. I have 3 years twin girls. Luckily the school started last week, I get no-noise moment for few hours during the day. Also this week, I found time to do coding in Swift.

  • Searching Greek and Hebrew with regular expressions

    According to the Python Cookbook, “Mixing Unicode and regular expressions is often a good way to make your head explode.” It is thus with fear and trembling that I dip my toe into using Unicode with Greek and Hebrew. I heard recently that there are anomalies in the Hebrew Bible where the final form of a letter is deliberately used in the middle of a word. That made me think about searching for such anomalies with regular expressions. I’ll come back to that shortly, but I’ll start by looking at Greek where things are a little simpler.

  • Java 15 Gains Garbage Collection, Text Block Features

    Java 15 became generally available on Sept. 15, marking the second release in 2020 of the widely deployed programming language. The Java 15 release follows Java 14, which debuted in March, and is noteworthy for a number of improvements, as well as the fact that the release was not delayed due to the COVID-19 pandemic.

Best Free and Open Source Terminal Session Recording

The vast majority of computer users depend on a graphical user interface, and fear the command line. However, the command line holds significant power and versatility. Commands issued from a shell offer system administrators a quick and easy way to update, configure and repair a system. The benefits of the command line are not only confined to system administration. The ability to transverse the file system quickly, give more information about files and directories, automate tasks, bring together the power of multiple console tools in a single command line, and run shell scripts are just a few examples of how the command line can offer a potent, multifarious toolbox.

Keep Tabs on Your To-Do Lists With This GNOME Extension

Task Widget is an open source GNOME extension that shows your to-do list embedded in the GNOME message tray (also known as the calendar or notification shade). This widget area displays your pending to-do items, and lets you check off tasks as you complete them. Task Widget is is able to integrate “…with GNOME Online Accounts and a number of GNOME applications, such as Evolution and To Do” but it is is not, by design, intended to replace any of those apps or services. Or to put it another way: it’s not a standalone task manager or to-do app. You can’t, for example, add a task from the widget area, or edit one either. You can only mark a task as done (or unmark it as done). Read more
