  • The Best Free Photo Editing Apps in 2021

    GIMP (GNU Image Manipulation Software) is flat-out one of the best editing applications available anywhere — for any price. Its suite of features is impressively full, and more are being added all the time.

    From layers, masks, and curves to brushes, clone stamps, and perspective changes, there is not a whole lot that GIMP can’t do compared to Adobe’s counterpart. Better yet, it is an open-source editor, meaning the huge community of users has created an extensive array of plugins that expand the functionality and abilities of GIMP. Some of these plugins come preinstalled, but there are tons more in its glossary that you can install in addition. If that weren’t enough, you can also use Photoshop plugins!

    Like Photoshop, however, this isn’t the greatest program for beginners as there is a rather steep learning curve.

  • The Apache News Round-up: week ending 4 June 2021

    Hello, June --let's take a look at what the Apache community has been up to over the past week...

  • A slightly-delayed monthly status update

    A few weeks ago, I announced the creation of a security response team for Alpine, of which I am presently the chair.

    Since then, the team has been fully chartered by both the previous Alpine core team, and the new Alpine council, and we have gotten a few members on board working on security issues in Alpine. Once the Technical Steering Committee is fully formed, the security team will report to the TSC and fall under its purview.

    Accordingly, I thought it would be prudent to start write monthly updates summarizing what I’ve been up to. This one is a little delayed because we’ve been focused on getting Alpine 3.14 out the door (first RC should come out on Monday)!


    Another project of mine personally is working to prove the reproducibility of Alpine package builds, as part of the Reproducible Builds project. To this end, I hope to have the Alpine 3.15 build fully reproducible. This will require some changes to abuild so that it produces buildinfo files, as well as a rebuilder backend. We plan to use the same buildinfo format as Arch, and will likely adapt some of the other reproducible builds work Arch has done to Alpine.

    I plan to have a meeting within the next week or two to formulate an official reproducible builds team inside Alpine and lay out the next steps for what we need to do in order to get things going. In the meantime, join #alpine-reproducible on if you wish to follow along.

    I plan for reproducible builds (perhaps getting all of main reproducible) to be a sprint in July, once the prerequisite infrastructure is in place to support it, so stay tuned on that.

  • HyperRogue turns the non-Euclidean roguelike into a VR experience and it's wild

    As if it wasn't confusing enough travelling through the non-Euclidean of HyperRogue, it's now also available to play through in different VR modes.

    Need a primer on HyperRogue? It's a roguelike, a traditional turn-based experience that you can play from different viewpoints (including first-person). What sets it apart is the wild geometry of the entire world taking place on the hyperbolic plane. Straight lines end up not being straight, going left can end up somewhere totally unexpected and the whole experience is just wacky. The game is "inspired by the roguelike genre (although in a very minimalist way), works of M. C. Escher, and by puzzle games such as Deadly Rooms of Death".

  • Arm Releases ASTC Encoder 3.0 With Even Better Performance - Phoronix

    Arm has released version 3.0 of its encoder for Adaptive Scalable Texture Compression (ASTC), the lossy compression algorithm popular with OpenGL (ES) and Vulkan that is royalty-free and available through official extensions.

    As with prior releases for Arm's ASTC command line compressor/decompressor, ASTC Encoder 3.0 is focused on more performance improvements. Arm engineers note that compared to ASTC Encoder 2.5, the new ASTC Encoder 3.0 should be "between 25% and 75% [faster]" depending upon the image quality and other settings. Using smaller block sizes and higher search qualities should yield the largest advantage in moving to ASTC Encoder 3.0. ASTC Encoder 3.0 aims to keep the image quality the same or better than ASTC Encoder 2.5.

  • IOTW: MacOS Security Patches Issued Again

    2021 has been tough for Apple, security-wise, as it relates to zero-day exploits.

Since the beginning of the year, Apple has had to issue a couple of security patches, first with macOS 11.3 and most recently with MacOS 11.4, both "Big Sur" releases.

  • 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.
