  • Updating Marble’s OSM Data Server

    Recently I wrote about options for getting OSM indoor map data for KDE itinerary’s work-in-progress indoor map feature for train stations and airports. The most flexible option mentioned there was using Marble’s OSM data tiles (which I had slightly misleadingly called “vector tiles”, a term in the OSM world usually referring to a different data format with much more application-specific pre-processing applied). Here’s an update on how this topic has progressed since.

    [...]

    With a full-scale pre-generation off the table, the obvious alternative would be on-demand generation of requested tiles. For this we can actually take quite some inspiration from how the OSM raster tiles are generated.

    The key elements there are mod_tile, an Apache extension for serving map tiles and managing a cache of those, and Tirex, a map tile generation scheduler. This setup isn’t limited to raster tiles, nor to any specific tile generator.

    OSM’s own statistics show that even on their much much wider used setup high zoom level tiles are only actually needed for a tiny fraction of the world’s surface, so there’s a lot of resources to be saved this way.

    Besides having to write a bit of glue code to interface Marble’s tile generator with Tirex, this however means that the generation of a single tile (or rather a batch of 8x8 tiles, the smallest unit Tirex works with) has to be fast enough for on-demand generation, as well as having a reasonably restrained memory consumption.

  • What play button have you been clicking on lately?

    Oh, hey! We didn't miss the weekend this time. Time for another community chat and giving out your latest recommendations.

    After mentioning last time about my current love affair with the Raspberry Pi 4, that has very much continued. Everything seems to be holding up nicely on it. There's been plenty of Steam Link game streaming, which has been quite the highlight due to how smoothly it has been working.

    For actual games though, I'm going to take this moment to totally plug CARRION again (see my review) because it's just wonderfully crafted. I'm now onto my second play-through to see if there are any fun things I missed. Sounds like it's been quite a successful launch too.

  • Sriram Ramkrishna: GNOME Extensions BoF – 18:00 UTC July 26, 2020

    We will be having a conversation around extensions and the future of how we will be handling them based on policy, community, and other important factors.

    If you are an extensions writer, then I would urge you to join our BoF to help understand what we will be doing with extensions going forward and also provide feedback. We do not want to do this in a vacuum.

  • Sparky APTus AppCenter

    It is improved APTus, still Yad based, but with HTML technology, and still as small, fast and lightweight as possible.

    Don’t expect it can be comparable to other existing AppCenters, it is not. It is still set of bash scripts wrapped up in Yad, but can be easy modified and enlarged as required.

    The matter of fact is, the development of the application I started with MoroS back in December 2018, and due to problems with Yad’s html dependencies, after a month or so I put it down.
    The second attempt was between December 2019 and January 2020; a newer version of Yad let me build it with the html option, but lack of time didn’t let me finish it again.

  • TenFourFox FPR25 available

    TenFourFox Feature Parity Release 25 final is now available for testing (downloads, hashes, release notes). There are no additional changes other than outstanding security updates. Assuming all goes well, it will go live on Monday afternoon/evening Pacific time.

  • Globalization: A history of openness

    In my career conducting international business, I traveled to more than 80 countries worldwide. I was always struck by how strongly regions of the world are connected, and I began studying the forces of globalization as a result.

    Several books on this subject were critical to this research. But the one I'd like to highlight here is World 3.0: Global Prosperity and How to Achieve It by Pankaj Ghemawat. This book first taught me how little the global community is connected—but also how far it has come compared to the past. During Prof. Ghemawat's research, he worked with DHL and ultimately helped develop the DHL Global Connectedness Index, which tracks how well the global community is interacting in four key measurements: trade, investment, telecommunication, and travel/migration. From that work, I developed and delivered a presentation on global connectedness, which stressed that the world should increase its scores on those four measurements of globalization, as they are directly linked to food supply, health, security, pollution, jobs and other global benefits.

  • Apple starts making first flagship iPhone in India

    India was the second-biggest smartphone market in the world in 2019, ahead of the US and second only to China. According to TechCrunch, Apple plans to scale up production in India, which would in turn reduce how much it depends on China, where most of its iPhones are currently made. And while Apple tops the premium smartphone market in India, it has only about a 1 percent share of the total smartphone market there. The iPhone’s price puts it out of reach for many consumers in India.

Games: Drink More Glurp, RimWorld, Jumpala and More

  • Party game 'Drink More Glurp' is an absolute barrel of laughs - out now

    Drink More Glurp, a party game that thoroughly parodies sporting events like the Olympic Games and also pokes fun at sponsorship systems is out now. Note: key provided by the developer. Set on an alien world where the inhabitants attempted to copy our sporty games, however they got everything just a little bit wrong which has resulted in a serious of ridiculous contests with completely mental physics. This might be the funniest party game I've played all year. After trying the original demo during the Steam Game Festival, I was hooked.

  • AntiMicro | Map Keyboard and Mouse Controls to Gamepad on openSUSE

    Installed a game called Pokemon Insurgence on Lutris and there was no way to play the game with a gamepad. Rather than try to fight things, set out for an application that would map the keyboard controls to the WiiU Pro Controller that has become my gamepad of choice. I know I heard it was possible on a podcast some time ago and since I was probably doing something else and didn’t have a notebook handy to write down whatever it was, I began my search and found this AntiMicro as a solution.

  • Vibrant twin-stick slasher 'Breakpoint' gives you exploding weapons

    Enjoy some classic fast-paced vibrant arcade-style action? Breakpoint looks like it's worthy of some attention for putting a nice unique spin on it. With bright neon graphics, they mixed in elements from the classic arcade games with "modern sensibilities". It's a top-down highscore chaser with melee weapons that…explode? Yes. No ranged attacks, no laser weapons, no pew-pew-pew. Instead you slice, crush, and blast your way through the swarm and when you push your weapons to their breaking point (it's called Breakpoint—get it?), they unleash a big explosion.

  • Steelbreakers turns the feel of classic Zelda into local multiplayer action

    The developer mentioned their idea with it was to make a game they wanted to play that they felt didn't exist already. As they said they "always wanted to play a Zelda game that demanded technical skill and would let you fight with your friends on a top-down 2d playing field" and so Steelbreakers was created. Together up to four players can fight for dominance in small arenas with traps and all sorts. At release, the developer is planning to have online play, additional game modes, plenty of maps and weapons, AI enemies and the list goes on. The demo is just a small slice of what to expect.

  • RimWorld gets a big 1.2 update out with lots more options to tweak your game

    The brilliant colony-building sim RimWorld has another mega post-release update available now, with content included for both the base game and the Royalty expansion. Looking over the changelog, which is as long as expected, it sounds excellent. RimWorld has gained a whole new way to tweak your experience with a "custom playstyle system", which allows you to adjust a large number of settings to how you want your game to be. So you could make it a lot easier and more of a building sim and less of a "oh my god everyone is going to die from raiders" sim. There's also a bunch of new visual effects and many new sound effects added in for free too. There's loads more, especially for the Royalty DLC like an entirely new major quest that involves defending a damaged shuttle or assaulting a bandit camp.

  • Competitive platform-jumper 'Jumpala' reveals new character, getting a free version

    Jumpala is an upcoming fast-paced competitive platformer that sees you constantly hopping across tiny little pads, it's actually brilliant fun and they've done a few new reveals recently. When you think about platformers, traditionally this would mean running along different floors, a little tricky jumping here and there and perhaps various enemy encounters. Jumpala is none of that. Instead, the whole arena scrolls upwards with small platforms each player needs to jump across, to turn it into their colour before it drops of the screen. It's highly competitive and from the early builds we played—a huge amount of fun.

  • Hilarious slapstick comedy game West of Loathing had an anniversary update

    Three years after launching, Asymmetric have given West of Loathing a big anniversary update to get rid of some issues and add in some silly new content. Even their version numbering is ridiculous, with this being update v1.11.11.11.1. From the creators of the browser-based comedy MMORPG Kingdom of Loathing, don't let the stick figures and super-simple style fool you, this is a great game worthy of your time and it's definitely funny. Easily on of 2017's best indie games. This is where you get to pick a character class between a Cow Puncher, a Beanslinger and a Snake Oiler so you know you're in a for a wild ride right away.

  • Check out the new trailer and demo for the sci-fi puzzle platformer Transmogrify

    Your facility appears to be overrun by strange creatures, with a forgetful research AI trying to help you escape but you do at least have a gun that can turn creatures into useful objects. This is Transmogrify, an upcoming sci-fi platformer that was partly funded on Kickstarter a few years back.
