  • Why Python's pip search isn't working: We speak to infrastructure director about ongoing traffic overload

    Last December, the Python development team overseeing the Python Package Index (PyPI) temporarily disabled the search endpoint on its XML-RPC API because its infrastructure has been overwhelmed by "abusive clients."

    The upshot is that searching for Python packages with pip, eg: pip search ascii or pip3 search png, isn't possible because this backend search API is unavailable.

  • Perl Lists - a Partial Taxonomy - DEV Community

    Mark Garder recently published the article A list of Perl list processing modules, a detailed and factual, unopinionated listing of eight Perl modules that manipulate lists. So, naturally, when his factual, unopinionated listing was cross posted to Redit, the first comment was the emotional, highly opinionated: “So how do we go about fixing this mess? Because it is a mess.”.

    Yes, the comment was mine.

    My intent was to see if we could create One List:: To Rule Them All. Not only does it confuse people who want to learn Perl to have various list functions in different modules (and to have functions that share a name across modules work differently), but it also confuses Perl veterans.

    And yes, once again, that’s me.

  • Rakudo Weekly News: 2021.21 Chattering

    Patrick Spek reports on behalf of the Raku Steering Council about the move of all Raku-related IRC channels from Freenode to Libera.chat, after most of the Freenode volunteers have left after what has been considered a hostile takeover. So if you want to chat with Rakoons, use the irc.libera.chat IRC servers from now on! The following channels have now effectively moved: #raku, #raku-dev, #moarvm, #cro, #mugs, #red and #raku-gamedev. And there is now also #raku-steering-council channel for direct communication with the Raku Steering Council.

  • Sometimes more data can hurt!

    So here’s a mind blower: In some cases having more samples can actually reduce model performance. Don’t believe it? Neither did I! Read on to see how I demonstrate that phenomenon using a simulation study.

  • Why I prefer making useless stuff

    There is nothing I find more liberating than to spend a Saturday afternoon coding on some toy project.

    There is no expectation or obligation to ever become more. It is just for fun, learning, and curiousity. I can add whatever features I want. I can use whatever technologies I want. I can throw it all away if I want. These are the projects I yearn for and look forward to when I'm busy with work.

  • KOTLIN, The enhanced Java

    A good programming language increases the readability of programs and their long-term maintainability. The faster the bugs can be fixed, the more time there isto develop a product. This is exactly where Kotlin comes in: The programming language on the Java Virtual Machine (JVM) has set itself the goal of preventing many errors from occurring in the first place. With zero safety , zero exceptions can be ruled out at compile time.

    A wealth of language constructs such as sealed classes , objects and inline classes make it possible to define data types that do not even allow inconsistent combinations which makes working with the language as pleasant as possible and despite the static typing, Kotlin can automatically determine the data type from the expression (type inference).

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
