  • Blockchain Firm Offchain Labs Releases Alpha Of Open-Source Scaling Solution

    New Jersey-based Offchain Labs has announced the launch of the Alpha 2 version of its scaling solution that can be easily integrated to any Etherum application.

    Led by a former White House Deputy Chief of Technology and a team of U.S.-based academics, Offchain Labs aims to make smart contracts more private, secure, and scalable using a combination of protocol design, incentives, and virtual machine architecture. The firm has invented Arbitrum, a blockchain agnostic Layer 2 scaling solution that incentivizes parties to agree off-chain how a virtual machine would act in order to improve transaction throughput, speed, and privacy.

  • As Crypto Markets Go Cold, Who Will Pay for Open-Source Code?

    Earlier this year IBM purchased Red Hat, the oft-referred to model for how open source can thrive, for $34 billion.

    Long the consultant to enterprises, IBM is going through a transitional period as a business and needs a boost. Red Hat’s open-source software offers IBM the ability to better compete in cloud services offered by Amazon, Microsoft and Google.

    Why is this important? Red Hat is one of the most name-checked examples of how open-source software can be successful. It is often used as an example of how championing open source can lead to business success. This is particularly pertinent to the cryptocurrency ecosystem, where open-source ethos rule the technology.

  • Fridge0: an open source hardware solar fridge with no battery requirement

    Joey Hess designed the first Fridge0 a year ago: it uses a standard chest freezer with added thermal mass, a simple controller, and a photovoltaic panel that effectively stores sunshine as coldness, obviating the need for expensive backup batteries.

  • Open Source Smart Smoker Brings The Heat (Slowly)

    Conceptually, cooking on a grill is simple enough: just crank up the flames and leave the food on long enough for it to cook through, but not so long that it turns into an inedible ember. But when smoking, the goal is actually to prevent flames entirely; the food is cooked by the circulation of hot gasses generated by smoldering wood. If you want a well-cooked and flavorful meal, you’ll need the patience and dedication to manually keep the fuel and air balanced inside the smoker for hours on end.

    [...]

    Ultimately, this project boils down to tossing a bunch of temperature sensors at the problem. The software developed by [HackersHub] takes the data collected by the five MAX6675 thermocouples and uses it to determine when to inject more air into the chamber using a PWM-controlled fan at the bottom of the smoker. As an added bonus, all those temperature sensors give the user plenty of pretty data points to look at in the companion smartphone application.

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.
