  • EY Open-Sources Tech It Says Slashes Cost of Private Ethereum Transactions

    In the updated code, EY said it's made additions that allow private transactions at scale by batching up to 20 ZKP transfers in one transaction – a factor it says "significantly" reduces costs. One 20-batch transaction would cost around $0.05, according to the announcement.

    ZPKs enable the sharing of information proofs between parties without revealing the information itself and, thus, removing the need for trust. The latest additions to EY's ZPK tech include batching tools and an enhancement that cuts the size of on-chain Merkle trees – a data structure fundamental to blockchains.

    A key factor of the advance, EY said, is that lowering the costs of transactions in this way makes the public ethereum blockchain more competitive with private blockchain networks.

  • 10 top distributed apps (dApps) for blockchain

    Because smart contracts, or self-executing business automation software, can interact with dApps, they're able to remove administrative overhead, making them one of most attractive features associated with blockchain. While blockchain acts as an immutable electronic ledger, confirming that transactions have taken place, smart contracts execute pre-determined conditions; think about a smart contract as a computer executing on "if/then," or conditional, programming.

    “DApps interact with smart contracts that are on the blockchain. So dApps support the user interface into the back-end smart contract that writes data to the blockchain,” said Avivah Litan, a vice president of research at Gartner.

    DApps run the gamut, from digital asset exchanges like LBank to online gambling like PokerKing and games like Cryptokitties. (LBank holds the equivalent of more than $1.4 billion in cryptocurrency.)

  • Sorry Steve, Open Source beat you

    CNBC Explores released a 14-minute documentary this month called "The Rise Of Open-Source Software" that open-source software "has essentially taken over the world".

    It points out that companies in every industry, from Walmart to Exxon Mobile to Verizon, have open-sourced their projects. Even Microsoft, whose former CEO, the shy and retiring Steve Ballmer (pictured) called open source "a cancer" has completely changed its point of view and is now seen as a leader in the space.

    In 2016 the US government even promised to open-source at least 20 percent of all its new custom-developed code."

  • 5 open source innovation predictions for the 2020s

    The concepts of containers and microservices were merely concepts before 2010, Ferris said. Then Docker launched in 2013, planting the early seeds of the container industry.

    At the same time, microservices — and the technologies to make them possible — were borne in open source through the Netflix OSS project.

    Docker went on to become one of the most influential technologies of the 2010s, giving rise to a myriad of new open source projects, including Kubernetes, which launched in 2015.

    Today, he noted, Kubernetes is the largest open source project on the planet. Companies are using the platform to transform monolithic application architectures, embracing containerized microservices that are supported by service mesh capabilities of projects such as Istio.

    "In the next decade, we anticipate that open source projects such as Istio, Kubernetes and OKD will focus on making containers and microservices smaller and faster to serve the needs of cloud-native development and to reduce the container's attack surface," Ferris said.

  • Fedora Update Weeks 46—52

    It’s been another little while since the last update. Mostly, this has been because the home Internet has been down for a while, so I’ve not been doing much Fedora stuff the last month. Prior to that little break though, updates were relatively steady.

    As a followup to the last update, I’ve now removed automated Suggests when they do not exist in Fedora yet from R packages that I do not own. This is a continuation of the work mentioned in the last update where I removed Suggests from my own packages.

    In any case, it looks like this will be the last update of the year. Over the last year, I’ve made ~1000 commits, created 133 new packages, and issued 1944 updates. This is about 4% of all Fedora updates over the past year.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
