  • Cutelyst 2.13 and ASql 0.19 released – Dantti's Blog

    Cutelyst the C++/Qt Web Framework and ASql the ASync SQL library for Qt applications got new versions.

    Thanks to the work on ASql Cutelyst got some significant performance improvements on async requests, as well as a new class called ASync, which automatically detaches the current request from the processing chain, and attaches later on when it goes out of scope.

    With the ASync class you capture it on your ASql lambda and once the query result arrives and the lambda is freed and the ASync object gets out of scope and continues the processing action chain.

  • LLVM Lands Very Basic Support For AMD Zen 3 CPUs

    While AMD has landed Znver3 support in GNU Binutils, the company hasn't yet sent out patches for either the GCC or LLVM/Clang compilers in setting up the Zen 3 target with its new instructions or optimized scheduling model / cost table. But a basic implementation has been merged to LLVM for allowing "-march=znver3" based on the limited public details thus far.

    Merged to mainline LLVM 12 yesterday was a basic implementation allowing for -march=znver3 targeting that basically flips on the new instructions known to be supported by Zen 3. Beyond Zen 2, it flips on INVPCID, PKU, VAES, and VPCLMULQDQ. There are also a few other instructions supported by Zen 3 as outlined in this earlier article.

  • CY's Take on PWC#083 | Moments on Perl or other Programming Issues [blogs.perl.org]

    I found that I use "and/or" quite frequently in writing. I know, (mathematical-)logically we only need "or". It seems to me to be a language tricky part as the use of gender neutral terms.

  • Warning about Python3 update in latest -current | Alien Pastures

    Warning for people running Slackware-current and have 3rd party packages installed (who doesn’t) that depend on Python3. That includes you who are running KDE Plasma5!

    The “Sun Oct 25 18:05:51 UTC 2020” update in Slackware-current comes with a bump in the Python3 version (to 3.9) which is incompatible with software which already has been compiled against an older version of Python3 (like 3.8).

    I found 26 of my own packages on my laptop that depend on Python3 and they are all probably going to break when upgrading to the latest slackware-current. This includes Plasma5 ‘ktown’ packages but also several of my DAW packages.

  • 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.
