  • Attack of the Clones with custom Proton builds for Steam Play

    I know how you all love to tinker, so how about tinkering away with some custom builds of Steam Play Proton on this fine Tuesday afternoon? There's a feature in the Steam client on Linux that enables you to add in your own special builds of Steam Play and other compatibility tools like Boxtron for native DOSBox. A very useful feature, since the community can build on top of work done by Valve to make Linux gaming with Steam Play even better. One such custom build of Proton which recently released is Proton-i 4.13-3. This one is quite simple with a few little updates and fixes like moving Proton 4.11-2 patches on top of Wine 4.13, a fix for Unreal Engine 4 and a few other little changes. Likely a good one to try, if you just want to be that little bit more up to date.

  • Mixing Tower Defense with production chains, the free and open source game Mindustry has a big update

    Could this be your next time sink? Mindustry merges together Tower Defense style gameplay with production chains from the likes of Factorio. A few days ago, the developer released the final 4.0 build which is an absolutely massive update to Mindustry. It took 88 builds to get there and it was worth the wait. It's an overhaul to all parts of the game including new gamemodes, customizable rules, a new editor, new graphics, new enemies, unit production, new progression, a campaign and more.

  • Wasteland 3 has an impressive new trailer for Gamescom

    inXile Entertainment have shown off more of their upcoming party-based RPG Wasteland 3 at Gamescom and it's looking great.

  • Areia: Pathway to Dawn aims to be a relaxing meditative adventure game

    Areia: Pathway to Dawn from Gilp Studio was just recently announced with the developer promising it to be a "journey like no other". It's an adventure game, with a few puzzle elements to it and a wondrous style. The developer said it's a game about emotions and spiritual growth, a tale of wonder as you explore a land inhabited by only one character. It's supposed to be a calming experience, with Gilp Studio saying it's "a unique addition to the range of meditative games".

  • GNOME 3.34 Works Out Refined XWayland Support For X11 Apps Run Under Sudo

    GNOME 3.34 continues to look like an incredibly great release in the performance department as well as for Wayland users. Earlier this summer, support was added to GNOME's Mutter to generate an Xauth file and passing it to XWayland when starting. The focus of that Red Hat contribution was for allowing X.Org/X11 applications to be run under XWayland as sudo. Up to this point when using sudo with an X11 app on Wayland, it hasn't worked out but this addition for GNOME 3.34 corrects that behavior.

    Adding to another creation being worked on by DragonFlyBSD lead developer Matthew Dillon, DSynth is a C rewrite of the FreeBSD originating Synth program that serves as a custom package repository builder.

  • RADV Vulkan Driver Lands Renoir APU Support In Time For Mesa 19.2

    Just hours ahead of the Mesa 19.2 feature freeze and days after the RadeonSI OpenGL driver added Renoir support, the RADV Vulkan driver has picked up support for this next-gen Zen 2 + Vega APU. The support comes down to just eight lines of new code for this new APU rumored to be launching in 2020. While it was hoped that this would be the first APU built on the Zen 2 CPU microarchitecture and with Navi graphics, the open-source Linux driver code drops have all pointed it to be more of a Raven/Vega refresh on the graphics side.

  • DevNation Live: Plumbing Kubernetes builds | Deploy with Tekton

    DevNation Live tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this talk, you’ll learn about Tekton, a Kubernetes-native way of defining and running CI/CD, from Kamesh Sampath, Principal Software Engineer at Red Hat. The session explores the characteristics of Tekton, which is cloud-native, decoupled, and declarative. This demo-filled session will show how to combine various building blocks of Tekton to build and deploy (Tasks and Pipelines) a Kubernetes application.

Security: Hacker Summer Camp, Nexus Repository, Ransomware, Web Server Security

  • Hacker Summer Camp 2019: CTFs for Fun & Profit

    Okay, I’m back from Summer Camp and have caught up (slightly) on life. I had the privilege of giving a talk at BSidesLV entitled “CTFs for Fun and Profit: Playing Games to Build Your Skills.” I wanted to post a quick link to my slides and talk about the IoT CTF I had the chance to play. I played in the IoT Village CTF at DEF CON, which was interesting because it uses real-world devices with real-world vulnerabilities instead of the typical made-up challenges in a CTF. On the other hand, I’m a little disappointed that it seems pretty similar (maybe even the same) year-to-year, not providing much variety or new learning experiences if you’ve played before.

  • Nexus Repository Now Supports APT

    Beginning with version 3.17, Nexus Repository Manager supports APT (Advanced Package Tool) repositories. APT is a set of tools used to search, install, and manage packages on Debian, Ubuntu, and similar Linux distributions. With this new release, you can now host your own local APT repos. Developers benefit from no longer having to rely on connecting externally to a public repository every time an often-used package is needed. In the case of Debian-based Docker containers, the ability to locally cache Debian packages from public repositories can save copious amounts of time when rebuilding your containers. This can do wonders especially for containers built frequently in a CI pipeline and for the more traditional use-case of provisioning virtual machines.

  • Ransomware attack has hit 20 government agencies in Texas [iophk: Windows TCO]

    This week the state of Texas has joined the list of targets. According to Texas’s Department of Information Resources (DIR), more than 20 local government entities have been impacted by a ‘coordinated ransomware attack.’ DIR states that “the Texas Military Department, and the Texas A&M University System’s Cyberresponse and Security Operations Center teams are deploying resources to the most critically impacted jurisdictions.”

    No disclosure has beeen made regarding how much of a payment is being requested, though given recent attacks on other states the amount is likely to be eye-watering. Also absent is any information on which ‘local government entities’ have been affected.

  • Web server security – Part 8: Basic log file analysis

    Tools like lnav (“The Log File Navigator”) allow quicker analysis of log files. Instead of manually searching for attack-like behavior, you can use SQL queries, load and combine multiple files at once, and switch between different views.

    However, keep in mind that not only tools but also underlying processes and organization are important. You must know where log files are stored, how they are created and how long information is available. This requires a basic security concept. Understand the structure of your log files, and use customization of logging rules if available.

Chromebooks Switching Over To The BFQ I/O Scheduler

On Chromebooks when moving to the latest Chrome OS that switches over to a Linux 4.19 based kernel, BFQ has become the default I/O scheduler. BFQ has been maturing nicely and as of late there's been an uptick in interest around this I/O scheduler with some also calling for it to be used by default in distributions. Google has decided BFQ is attractive enough to enable by default for Chromebooks to provide better responsiveness. Read more
