  • Fresh from the Python’s den: PyPy turns 7.1, Facebook open-sources Python Test Runner

    Python interpreter and CPython replacement PyPy has been released in version 7.1, which should give you a speed boost, by no longer converting strings to unicode internally. Instead, it now uses UTF-8 for representation.

    Speaking of speed, long operations with an operand fitting into an int should need less computing time after the update. Register allocation in the JIT uses better heuristics now and d_type and d_name members of builtin descriptors get correctly initialised which should protect you from nasty segmentation errors.

    The PyPy team also improved the ability to use the buffer protocol with ctype structures and arrays and updated the CFFI backend (C Foreign Function Interface) to version 1.12.2. Additions to the __pypy__ documentation are meant to help those looking into using the special features contained within that module. Details can be found in the project’s changelog.

  • Imagine Communications, Telestream Join the SRT Alliance

    The SRT Alliance, supporting the SRT Open Source Project, announces that 39 more companies have recently endorsed the SRT protocol for low latency video streaming, including Imagine Communications, Net Insight, Red Bee Media, Telestream.

  • SRT Alliance Welcomes Avid to the SRT Open Source Video Streaming Project

    SRT (Secure Reliable Transport) is an open-source protocol, developed by Haivision, which allows broadcasters and streamers to deliver high-quality, low-latency streams across the public internet. SRT is fast becoming the de facto low-latency video streaming standard in the broadcast and streaming industries.

  • SD Times Open-Source Project of the Week: Pagedraw

    Though Pagedraw closed its doors as a business at the beginning of this month, the web-based React UI building utility lives on as an open-source project. The project was designed to provide an “effortless” way to design a UI, down to supporting mock-up import from similar applications Figma and Sketch.

    After designing or importing a UI in the application, Pagedraw can export them as JSX code.

    There is a catch. In the farewell post on the tool’s now-defunct website, developers Jared Pochtar and Gabriel Guimaraes admitted the faults in their vision.

  • 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.
