  • Some Compiler Performance Benchmarks With The Zapcc Caching Compiler

    Here are some quick benchmarks I ran this week of the newly open-sourced Zapcc C++ caching compiler based upon LLVM/Clang and compared to the upstream Clang performance, GCC, and Ccache with the speed on the original compilation of the benchmark code and then again on a subsequent compilation.

  • PHP 7.3.0 alpha 1 Released

    PHP team is glad to announce the release of the first PHP 7.3.0 version, PHP 7.3.0 Alpha 1. This starts the PHP 7.3 release cycle, the rough outline of which is specified in the PHP Wiki.

  • PHP 7.3 Alpha 2 Released With Many Bug Fixes

    Just shy of two weeks since PHP 7.3 went into alpha, the second alpha release of this upcoming annual feature release to the PHP programming language is now available.

    PHP 7.3 has been working on several new functions, WebP support within the image create from string function, improved PHP garbage collection, and a variety of other features and improvements. While PHP 7.3 is still open for new features, PHP 7.3 Alpha 2 comes with just bug fixes. Bug fixes for alpha two range from core fixes to various bugs in its ZIP, EXIF, Date, and CLI code, among other areas. The fixes are outlined here.

  • Python virtual environments

    In a short session at the 2018 Python Language Summit, Steve Dower brought up the shortcomings of Python virtual environments, which are meant to create isolated installations of the language and its modules. He said his presentation was "co-written with Twitter" and, indeed, most of his slides were of tweets. At the end, he also slipped in an announcement of his plans for hosting a core development sprint in September.

  • A Python static typing update

    One of the larger features added to Python over the last few releases is support for static typing in the language. Static type-checking and tools to support it show up frequently as topics at the Python Language Summit (PLS) and this year was no exception. Mypy developers Jukka Lehtosalo and Ivan Levkivskyi gave an update on static typing at PLS 2018.

    Lehtosalo started things off by talking about stub files, which contain type information for libraries and other modules. If you are going to type-check code that uses outside modules, from the standard library or a third-party library, the tool needs to understand the types used in the public interfaces of the library. The type-checking that can be done is limited if there are no stubs for the libraries used.

  • Linux distributions and Python 2

    Python 2.7 will reach its end of life in less than two years—at least for the core development team. Linux distributions need to figure out how to handle the transition given that many of their users are still using that version of the language—and may still be well beyond the end-of-life date. Petr Viktorin and Matthias Klose led a session at the 2018 Python Language Summit to discuss distributions' approaches to deprecating Python 2.

    Viktorin works for Red Hat and focused on the Fedora distribution. He wants to help figure out how to help the Python downstreams so that Python 2 can be fully discontinued. There are two different ways to do that; either make sure that everyone switches to Python 3 or simply deprecate Python 2 and "wash our hands" of the problem. He would prefer the first alternative. He will be working on this transition for Red Hat as part of his day job and would like to do it in the community as well; that will minimize the need to maintain Python 2 going forward.

  • 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.
