  • Wine Launcher 1.4.46 Is Released

    Wine Launcher is a simple front-end for Wine that lets you use separate WINEPREFIX= prefixes and different configurations for each game you install using it.

    Wine Launcher version 1.4.46 is the seventh minor version of it that has been released this month. The Russians are producing new releases on a near-daily basis. A lot of new features have been added in the last dozen releases. The latest versions allow you to compress games to SquashFS images, the PipeWire multimedia server is now supported, VKD3D Proton has been added to the long list of Wine implementations a game can be configured to use, it is now possible to install libraries using Winetricks and the launcher itself has been re-designed.

  • KenShape is a new tool to get easy 3D models from 2D pixel-art by Kenney | GamingOnLinux

    Want a quick way to make 3D models? Here's your fresh tip of the day for prototyping, game development or anything else - check out the new KenShape application from Kenney. For those unaware Kenney is the developer of games like Pixross, Frick, Inc., the Asset Forge application to bash together blocks to make 3D models and — oh, an absolute ton of high quality assets both paid and public domain.

    Their latest work is quite brilliant with KenShape. You draw something in a pixel-art block style, give it some depth based on numbers 1-8 with 1 being thin and 8 being quite large and it will then generate a proper 3D model of it. You can preview it first though of course but the result is quite remarkable. Generated models can be exported to various 3D formats compatible with most game engines (including Unity, Unreal Engine, Godot, Asset Forge, Blender and PlayCanvas), or as .vox files compatible with voxel software like MagicaVoxel.

    Thanks to itch.io having easy press access to anything on the platform (as long as developers hit the right checkboxes), I took it for a spin since it offers full Linux support.

  • Khronos and EMVA collaborate on embedded camera standards [Ed: Has an NDA problem]

  • 3.5-inch Elkhart Lake SBC offers triple GbE ports

    Ibase’s -40 to 85°C ready “IB836” SBC runs Ubuntu or Windows on an Atom x6000 with up to 32GB DDR4, 3x GbE, 3x USB 3.1, DP, Type-C with DP, 2x SATA, mini-PCIe, and M.2.

    Avalue revealed the first 3.5-inch SBC based on Intel’s Elkhart Lake back in September with its ECM-EHL, and now Ibase has posted a preliminary product page for its own 3.5-inch entry. The IB836 offers triple 1GbE ports instead of the GbE and 2.5GbE ports found on the ECM-EHL or the dual GbE ports on Congatec’s smaller, Elkhart Lake based Conga-PA7 Pico-ITX board.

  • Syslog-ng on BSDs

    My FOSDEM presentation in the BSD devroom showcased what is new in sudo and syslog-ng and explained how to install or compile these software yourself on FreeBSD. Not only am I a long time FreeBSD user (started with version 1.0 in 1994) I also work on keeping the syslog-ng port in FreeBSD up to date. But soon after my presentation I was asked what I knew about other BSDs. And – while I knew that all BSDs have syslog-ng in their ports system – I realized I had no idea about the shape of those ports.

    [...]

    In this blog I identified many problems related to syslog-ng in various BSD port systems. I also provided some workarounds, but of course these are not real solutions. I cannot promise anything, as I am not an active user or developer of any of these BSD systems and I am also short on time. However, I’m planning to fix as many of these problems at the best effort level, as time allows.

Their relevant code tends to be hosted through AmpereComputing on GitHub.

  • Lessons Learned From the SolarWinds Supply Chain Hack

    In a recent Linux Foundation blog post titled “Preventing Supply Chain Attacks like SolarWinds,” the foundation’s Director of Open Source Supply Chain Security, David A. Wheeler, adamantly pushed the need for software developers to embrace the LF’s security recommendations to prevent even worse assaults on government and corporate data security in the wake of the rampant data breach.

    Wheeler’s post is timely and filled with information to make it harder for hackers to exploit the future systems we all depend on. He includes 11 Linux Foundation recommendations including how organizations can harden their build environments against attackers, the need to begin shifting towards implementing and then requiring verified reproducible builds, and the practice of changing tools and interfaces so unintentional vulnerabilities are less likely.

    According to Wheeler, SolarWinds met some of the foundation’s defensive measures. None of them prevented the successful SolarWinds attack, he said. More software hardening is needed.

    The SolarWinds Orion software product is proprietary. So how can open-source coding methods help create better security?

  • M1 MacBook SSDs are facing a big problem — and it could kill your laptop

    The new M1 chip in Apple's latest MacBooks offers great performance and battery life. It may not be so good for your storage drive, however.

    On Twitter and several other forums, users of the latest MacBook Air, MacBook Pro and Mac Mini models are reporting solid-state-drive (SSD) wear rates far higher than expected. If the figures are accurate and the trend continues, it could mean worryingly short lifespans for Apple's latest batch of laptops.

    [...]

    In the case of the tested Macs seen in these threads, one Mac Mini user claimed to have written 165TB of data in just two months of use. Compared to equivalent retail SSDs from Toshiba (who supplies the SSDs inside the MacBooks), that's equivalent to 10% of its total warrantied TBW.

    In theory, the SSDs in Apple's M1 MacBooks should guarantee reliable use for around five years. But this rapid rate of use slashes that reliable life to less than two years.

    This 10% figure seems to be an outlier. Most users complaining about this issue are reporting figures of 2-3% usage, as seen on threads on the MacRumors forum and the LinusTechTips forum. That's still higher than you'd expect for a brand-new device, though.

  • 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.
