  • Osmo PIM 0.2.14 compiled in OpenEmbedded

    Very good news about Osmo. "PIM" means Personal Information Manager, and Osmo has been in the pups for a very long time. However, it is somewhat neglected and not as well integrated as could be.

    The way this latest work with Osmo came about, is I have an elderly relative who has a mobile phone with prepaid account with a telco. I pay it, every 4 weeks. Don't want to do a direct-debit with a bank, so renewal requires me to remember when to pay... and I forget.

    Besides, renewal is peculiar. I have to pay $15 for the renewal, then separately have to pay $5 international-calls addon. That second payment requires a manual online choice. I cannot see how to automate this with direct-debit or bpay. The telco is Optus.

  • 3 Best Free and Open Source JavaScript Engines - LinuxLinks

    JavaScript is an interpreted programming language. It means that source code isn’t compiled into binary code prior to execution. The role of the JavaScript engine is to turn plain text script into executable code. In other words, the engine is a container in which you run your program.

    JavaScript engines are often developed by web browser vendors, and every major browser has one. In a browser, the JavaScript engine runs in concert with the rendering engine via the Document Object Model. JavaScript engines implement specification of the language provide by ECMAScript. Standardization enables the development of independent engines and ensures scripts give the same results no matter wherever they run.

    The first JavaScript engines were mere interpreters, but all relevant modern engines use just-in-time compilation for improved performance.

    The use of JavaScript engines is not limited to browsers. For example, the V8 engine is a core component of the Node.js and Deno runtime systems.

    Engines which use runtime interpreters and do not compile into native machine code are excluded from this roundup.

    Here’s our verdict captured in a legendary ratings chart. We feature free and open source software only here.

  • Kasm Workspaces - Stream Docker Containers Easily & Quickly

    Kasm Workspaces is an intriguing platform for security and development aficionados. It is accessible by web browser and allows users to deploy container apps, including full-fledged Ubuntu desktops.

    In our daily lives, we must deal with a wide range of challenges that arise in our workplace. As an independent developer, I am concerned with designing secure code, optimizing application speed, and hunting and fixing bugs. But what if, when searching for something on the Internet, I accidentally click on a site that steals my session or downloads ransomware or malware? That is beyond frustrating. Isn’t that right?
    Every day, I’m sure firms of various sizes have the same difficulty. What if one of their employees accidentally downloads malware in the workplace? Kasm Workspaces, on the other hand, attempts to solve the same problem to a large extent.

  • Fooled by complexity | Playing Perl...

    And that fool would be me. After realising that HyperSeq is lazy, I managed to simplify the code in my last post.

    [...]

    The sub needle transforms it’s argument or returns Nil. By turning Nil into Empty, any call to .head will skip all values that where not a hit. At least for strongly CPU-bound tasks, which allow for small batch sizes, .hyper doesn’t overshoot much.

  • GStreamer Rust bindings 0.18.0 release

    A new version of the GStreamer Rust bindings, 0.18.0, was released. Together with the bindings, also a new version of the GStreamer Rust plugins was released.

    As usual this release follows the latest gtk-rs release and the corresponding API changes.

    This release includes optional support for the latest new GStreamer 1.20 APIs. As GStreamer 1.20 was not released yet, these new APIs might still change. The minimum supported version of the bindings is still GStreamer 1.8 and the targetted GStreamer API version can be selected by applications via feature flags.

  • 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.
