  • Steinar H. Gunderson: Speed

    My OS: One core can run 10 million random I/O operations per second and minify JSON at 6 GB/sec.

    Also my OS: Firing up a new terminal gives a one-second delay where the shell reads its 24 MB history file, and getting ten new emails makes my mail reader reflow all threads ten times, giving jank of several seconds.

  • Better Perl: Four list processing best practices with map, grep, and more

    First, some cred­it is due: these are all restate­ments of sev­er­al Perl::Critic poli­cies which in turn cod­i­fy stan­dards described in Damian Conway’s Perl Best Practices (2005). I’ve repeat­ed­ly rec­om­mend­ed the lat­ter as a start­ing point for higher-​quality Perl devel­op­ment. Over the years these prac­tices con­tin­ue to be re-​evaluated (includ­ing by the author him­self) and var­i­ous authors release new pol­i­cy mod­ules, but perlcritic remains a great tool for ensur­ing you (and your team or oth­er con­trib­u­tors) main­tain a con­sis­tent high stan­dard in your code.

    With that said, on to the recommendations!

  • Project Wakefield Is OpenJDK's Effort To Improve Java On Wayland - Phoronix

    Project Wakefield formally got off the ground in September with its focus to provide native Wayland support. Given Linux distributions continue moving away from X.Org Server based sessions by default in favor of Wayland, OpenJDK developers are working to get their Wayland desktop support in order. Initially they are working to provide good support for JDK running on Wayland within the X11 compatibility mode while the ultimate goal is to offer complete and native Wayland client support. OpenJDK developers have acknowledged this will "take years to fully complete and deliver" their native Wayland support.

  • 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.
