Games: Akurra, RimWorld and Space Grunts 2

  • Akurra to support Linux without a stretch-goal on Kickstarter

    Game developer Jason Newman who is currently crowdfunding Akurra, mentioned here on GOL recently, has decided they no longer need a stretch-goal for Linux support.

    What is Akurra? A retro styled puzzle game, inspired by the likes of Chip's Challenge, Star Tropics, Sokoban, and Zelda. Push blocks into holes and over pits, avoid spikes, explore caves, and ride sea turtles in order to find keys, gems, and stars that unlock new paths and friends to aid you as you explore a collection of islands chock-full of puzzles and secrets.

  • The latest RimWorld update opens up more possible paths

    RimWorld was already a deep game, with so much on offer it's easy to get completely sucked into it and now that's going to be even more possible.

    With the latest update, the developer mentioned their aim has been to open up RimWorld to more progression paths. Enabling you to take the game in whatever direction tickles your fancy including tribal, outlander, pro-Empire, anti-Empire, neutral Empire, use Psycasters or not, use drugs or not, use ranching or not and whatever else. The point was to have the game AI and world respond sensibly to where you're headed.

  • Space Grunts 2 is a roguelike with card-based combat out now

    Merging together elements of a card-based deckbuilder with a traditional turn-based roguelike, Space Grunts 2 from Orangepixel has now left Early Access. Note: Key provided by the developer.

    This is the 9th game from Orangepixel to support Linux, and might possibly be my favourite yet! A very easy to get into game, with a satisfying gameplay loop that sees you travel through procedurally generated sci-fi environments with a tight pixel-art style.

[$] Capacity awareness for the deadline scheduler

LWN.net - Pet, 05/29/2020 - 19:45
The Linux deadline scheduler supports realtime systems where applications need to be sure of getting their work done within a specific period of time. It allocates CPU time to deadline tasks in such a way as to ensure that each task's specific timing constraints are met. However, the current implementation does not work well on asymmetric CPU configurations like Arm's big.LITTLE. Dietmar Eggemann recently posted a patch set to address this problem by adding the notion of CPU capacity to the deadline scheduler.

Mozilla and Firefox Leftovers

  • Marco Zehe: Welcome to Marco's Accessibility Blog 2.0!

    Well, after 13 years, I felt it was time for something new. Also, as I wrote recently, Mozilla now has a dedicated accessibility blog, so I feel that I am free to do other things with my blog now. As a sign of that, I wanted to migrate it to a new platform.

    This is not to say the old platform, WordPress, is bad or anything like that. But for my needs, it has become much too heavy-weight in features, and also in the way how it feels when performing day to day tasks. 80% of features it offers are features I don't use. This pertains both to the blog system itself as well as its new block editor. But those features don't get out of the way easily, so over the months and actually last two to three years, I felt that I was moving mountains just to accomplish simple things. It has nothing to do with the steadily improving accessibility, either. That is, as I said, getting better all the time. It just feels heavy-weight to the touch and keyboard when using it.

  • Jeff Klukas: Encoding Usage History in Bit Patterns

    Monthly active users (MAU) is a windowed metric that requires joining data per client across 28 days. Calculating this from individual pings or daily aggregations can be computationally expensive, which motivated creation of the clients_last_seen dataset for desktop Firefox and similar datasets for other applications.

    A powerful feature of the clients_last_seen methodology is that it doesn’t record specific metrics like MAU and WAU directly, but rather each row stores a history of the discrete days on which a client was active in the past 28 days. We could calculate active users in a 10 day or 25 day window just as efficiently as a 7 day (WAU) or 28 day (MAU) window. But we can also define completely new metrics based on these usage histories, such as various retention definitions.

  • Mozilla VR Blog: WebXR Viewer 2.0 Released

    We are happy to announce that version 2.0 of WebXR Viewer, released today, is the first web browser on iOS to implement the new WebXR Device API, enabling high-performance AR experiences on the web that don't share pictures of your private spaces with third party Javascript libraries and websites.

    It's been almost a year since the previous release (version 1.17) of our experimental WebXR platform for iOS, and over the past year we've been working on two major changes to the app: (1) we updated the Javascript API to implement the official WebXR Device API specification, and (2) we ported our ARKit-based WebXR implementation from our minimal single-page web browser to the full-featured Firefox for iOS code-base.

  • Mozilla VR Blog: Scaling Virtual Events with Hubs and Hubs Cloud

    Virtual events are unique, and each one has varying needs for how many users can be present. In this blog post, we’ll talk about the different ways that you can consider concurrency as part of a virtual event, the current capabilities of Mozilla Hubs and Hubs Cloud for supporting users, and considerations for using Hubs as part of events of varying sizes. If you’ve considered using Hubs for a meetup or conference, or are just generally interested in how the platform works, read on!

  • Extensions in Firefox 77

    Firefox 77 is loaded with great improvements for the WebExtensions API. These additions to the API will help you provide a great experience for your users.

    Optional Permissions

    Since Firefox 57, users have been able to see what permissions an extension wants to access during the installation process. The addition of any new permissions to the extension triggers another notification that users must accept during the extension’s next update. If they don’t, they won’t receive the updated version.

    These notifications were intended to provide transparency about what extensions can do and help users make informed decisions about whether they should complete the installation process. However, we’ve seen that users can feel overwhelmed by repeated prompts. Worse, failure to see and accept new permissions requests for updated versions can leave users stranded on older versions.

  • Moving SUMO Community synchronous communications to Matrix

    As some of you already know, Mozilla has been working for some time to replace its official synchronous communication tool, and earlier this year we decided to launch our own Matrix instance to host our public conversations.

    In SUMO, we historically maintained a Telegram group to enable synchronous communications, and now we want to transition it to the new Mozilla Matrix.
