  • New AMD Zen 3 Fixes Published For The GCC 11 Compiler - Phoronix

    Last week there were a few round of Zen 3 compiler patches published and quickly merged into the GCC 11 compiler code-base ahead of its imminent release, This week there is some new activity albeit fixes for this new "Znver3" target.

    Last week saw several patches for working to tune the Znver3 GCC 11 support with correct latencies for more instructions and other optimizing. Today SUSE's Jan Beulich merged a number of GCC x86-64 fixes, including specifically for the Zen 3 support.

  • Qt Creator 4.15 Beta2 released

  • Paul E. Mc Kenney: Parallel Programming: Second Edition

    The first edition of “Is Parallel Programming Hard, And, If So, What Can You Do About It?” is now available. I have no plans to create a dead-tree version, but I have no objection to others doing so, whether individually or in groups.

  • A small billion-object Swift cluster

    In the latest of Swift numbers: talked to someone today who mentioned that they have 1,025,311,000 objects, or almost exactly a billion. They are spread over only 480 disks. That is, if my arithmetic is correct, 2,000 times smaller than Amazon S3 was in 2013. But hey, not everyone is S3. And they aren't having any particular problems, things just work.

  • PostgreSQL Full-Text Search Examples – Linux Hint

    Any database should have an effective and versatile search capability. Whenever it refers to databases, PostgreSQL is a master of all crafts. It combines all of the things you’ve grown to love with SQL with a slew of non-SQL database functionalities. Any of these Non-SQL functions, such as the JSONB information sort, are fantastic, and you wouldn’t even have to try a different database. Full-Text Search is among the newest Non-SQL features incorporated into PostgreSQL. Is PostgreSQL’s complete-text search completely functional, or would you want a distinct search index? If you can somehow develop a complete text search deprived of adding one more cover of code, it would be a fantastic idea. You’re already acquainted with pattern search in the MySQL database. So, let’s have a look at them first. Open the PostgreSQL command-line shell in your computer system. Write the server title, database name, port number, username, and password for the specific user other than default options. If you need to slog with default considerations, leave all choices blank and hit Enter each option. At the moment, your command-line shell is equipped to work on.

  • Regular Expression Basics in C++ – Linux Hint

    Consider the following sentence in quotes,
    “Here is my man.”

    This string may be inside the computer, and the user may want to know if it has the word “man”. If it has the word man, he may then want to change the word “man” to “woman”; so that the string should read:

    “Here is my woman.”

    There are many other desires like these from the computer user; some are complex. Regular Expression, abbreviated, regex, is the subject of handling these issues by the computer. C++ comes with a library called regex.

  • I finally escaped Node (and you can too)

    Languages like Elixir and Ruby are an act of creation. Ruby, for example, reduces to a creator and designer (Matz). You can feel His embrace from first contact with the language. It is welcoming. It is warm. Things feel purposeful. They make sense. Ruby's principle of least surprise makes everything feel in order.

    JavaScript is exactly the opposite. JavaScript is evolution. Node is full of surprises, at every turn, for every skill level. JavaScript will always find little ways to undermine you, to humiliate you. There is no one designer, just the cold force of natural selection. It is riddled with arcane evolutionary quirks. It is direct democracy, the people's language, for better and worse.

    The history of JavaScript is complex and deeply human. And perhaps one day the story of collapse into a singularity. I can't wait to read the book.

    But might ≠ right, and I'm happy I've finally broken free.

  • How to Move the File into Another Directory in Python – Linux Hint

    The file is used to store data permanently. Sometimes we require to move the file location from one path to another path for the programming purpose. This task can be done by using Python script in multiple ways. Move () is the most used method of Python to move the file from one directory to another directory defined in the shutil module. Another way of moving file location by using rename() method that is defined in the os module. These two methods can be used to move the file from one directory to another directory, as explained in this tutorial.

  • 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.
