  • The state of toolchains in OpenBSD

    Following the OpenBSD 6.9 release, OpenBSD-current has been updated to LLVM 11.1.0 and GCC 4.2.1 is not built anymore on amd64. GCC 8.4.0 (released in March 2020) is available in the ports collection.

    Among the remaining platforms still using GCC 4.2.1 as the default compiler, only sparc64 will be able to switch in the future. LLVM has a Sparc V9 backend and work has been done in OpenBSD to make the switch possible. For all the other remaining ones, there are no alpha, hppa, sh4, nor m88k backends in LLVM, and even if this changed in the future, the hardware is too slow to be able to self-host the compiler.

  • A Spooky Cute House - Krita Digital Painting Timelapse

    Here is an artwork (click on the picture above for the 3510x1740px resolution) plus a video timelapse of a digital painting of a Spooky Cute House made using Krita. I made this artwork for myself, a single day personal project to train with my new XP-Pen Pro Artist 24 pen display. The tablet was sponsored; this video is not. XP-Pen sent me Promo codes and I mention it in the beginning of the video so my audience can benefit with a discount. That's all.

    So, after a week, what do I feel about the tablet? This tablet reminds me a lot the Cintiq 21UX: the smooth surface, the parallax the compact frame; but it is way better than the 21UX thanks to the QuadHD monitor, the colors, the stylus. The Digimend driver hack works fine for me. I'll still prefer my large Intuos4XL because I prefer non-display tablets for the ergonomics; but I'll keep the XP-Pro 24 next to me as my second monitor; so when I need to sketch, I don't plug the Cintiq13HD anymore but I just swing the 24Pro on a Ergotron arm I connected to it. Good setup, the "detailing step" was a pleasure to do on this device.

  • Stephen Michael Kellat: Say What Now?

    I do have some amd64 hardware revived and it is running Xubuntu Impish Indri. It is very early on so it is not as if there has been any opportunity for anything to go wrong. I will have to come up with something wild or crazy to push limits this cycle in terms of testing that box, I suppose.

  • Ubuntu Blog: Data Lake, Data Lab, Data Hub: what’s the difference?

    Lakes are tranquil, large pools of cool water, right? Well possibly. I grew up in Scotland, where lakes are called lochs, and rumours of monsters that lurk in the depths of ancient lochs abound. Scotland also has salt water sea lochs, full of stinging jellyfish. But one thing is for sure – lakes, lochs, call them what you will – they’re popular places to go fishing.

    In current technology vernacular, a data lake is essentially a very large body of cool data, typically in the 100s of terabytes to petabytes in size. The data lake differentiates from other cool storage systems such as MAIDs (Massive Array of Idle Disks), storage vaults and tape archives, because the data remains online and fully accessible on a low-cost storage media like Apache HDFS, Ceph, or AWS Simple Storage Service (s3). This makes it an interesting and cost-effective solution for performing ad-hoc research, analysis and reporting on the aggregated data – essentially enabling data “fishing expeditions”, as well as being the feedstock for applications using deep learning or other data-intensive artificial intelligence approaches. The “big data” need not be restored from a tape or extracted from a vault or deep storage solution in order to be queried, which are tasks that usually come with a significant cost.

    Data in the lake can take many forms, the most popular format is semi-structured machine data – for example telemetry data (system, application usage and activity logs, user tracking, things like that), log data (weblogs, crash logs, network element logs, application logs, firewall logs, industrial machine data and so on) and data feeds (like stock ticker data, weather data, etc.). Another popular format is system of record (SoR) data – operational database extracts, data warehouse change data capture, and so on. And many data lakes capture vast amounts of unstructured data (free-text – like chat or audio transcriptions, document scans, binary photographs and images like x-rays, binary audio – like call centre recordings, and binary video – like security camera recordings).

  • Wind River’s enhancements deliver cybersecurity and anti-tamper protection

    The latest version of Wind River Titanium Linux, developed by the Wind River technology protection and cybersecurity group Star Lab, offers a robust Linux system-hardening and security capability and is available on the market for operationally deployed Linux systems. Key features for Titanium Linux include secure boot, anti-tamper protections, and the ability to simplify mandatory access control (MAC) policy creation.

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.
