  • GCC 9 Feature Development Is Ending Next Month

    There is just three weeks left for GNU toolchain developers to finish landing new feature material in GCC 9.0 ahead of next year's GCC 9.1 stable release.

    Richard Biener of SUSE announced today that GCC's "stage 1" development will shift to "stage 3" on 11 November. This marks the point at which open feature development is over and will then focus on bug-fixing... No new features are generally allowed in during this stage. On 6 January 2019 is when they intend to begin their final period of only working on regression fixes and documentation updates.

  • GCC's Test Suite To Begin Testing C++17 By Default

    GCC's test suite will soon begin testing the C++17 standard as part of its C++98/11/14 standard tests by default... This doesn't affect the default C++ standard used by the GCC G++ compiler at this point, but at least will help eliminate any lingering C++17 bugs as well as helping to stop regressions in the future.

    With the GCC test suite's test cases having cleared through the last of the C++17 issues, Marek Polacek of Red Hat sent out the patch today to begin testing C++17 by default when running its test suite. C++17 is tested in addition to the earlier C++98, C++11, and C++14 standards.

GCC 9 Compiler Adds -std=c2x And -std=gnu2x

  • GCC 9 Compiler Adds -std=c2x And -std=gnu2x For Future C Language Update

    With GCC 9 feature development ending in a few weeks, it's now a mad dash by developers to land their last minute additions into this annual open-source compiler update -- including a look ahead for what is coming down the pipe in the compiler space.

    Joseph Myers of CodeSourcery landed on Wednesday the initial C language standard compiler switches for the upcoming C2X standard. This update that for now is just dubbed C2X is currently in a draft standard with feature development still happening for this next C programming language update. In preparing for that, to GCC 9 he has added support for the -std=c2x and -std=gnu2x (for the GNU C dialect of C2X) switches so developers can specify using this newer version of C.

  • 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.
