Games: Tannenberg, Project Zomboid and Jackbox Party Pack 6

Filed under
Gaming
  • Tannenberg the WWI FPS adds the new Ukraine map, still on sale in a bundle

    M2H and Blackmill Games have just release another pretty big update to Tannenberg, their impressive WWI first-person shooter.

    Today's update adds in the Ukraine map which the developers say has plenty of open ground for HMGs to get you in their sights, with extensive trench networks to give some cover.

  • Project Zomboid just had the biggest Beta release ever overhauling loads of features

    Move over 7 Days to Die, you're not the only Zombie survival game in town with a recent overhaul. Project Zomboid is another that just released an absolutely massive Beta update to try out.

    Included in their "IWBUMS" (I Will Back Up My Save) Beta branch on Steam (not on GOG until stable) is the first step towards Project Zomboid version 41. The amount of changes included is quite ridiculous. The Indie Stone even said it's the "most fundamental and wide-ranging update that Project Zomboid has ever had" and they're not wrong.

    This latest Beta is work towards making Project Zomboid feel a little more alive and have a wider variety for everything. It's a foundation to bring even more big changes to PZ, with the new animation work in this build helping to bring wild animals in the next major build. This Beta is expected to last a while, as they have more to add back into it.

  • The Jackbox Party Pack 6 has officially released with Linux support

    In the mood to have a party? Well you're in luck as The Jackbox Party Pack 6 is now available with Linux support. Continuing their great support of Linux gaming, all six packs have Linux versions which is excellent!

    What makes the Jackbox Party Pack (any of them) great is how you connect to play them. No need to hook up 4 or 5 gamepads, stretch wires across the floor or anything annoying like that. You load the game, tell everyone to pull out their phone or tablet and connect up to their website with a room code and—pop, you're in the game.

GhostBSD Reaffirms To Being TrueOS+BSD Desktop OS With Official MATE Desktop

Filed under
BSD

With Project Trident moving away from a TrueOS/FreeBSD base to instead Void Linux, if you are looking for a good BSD-based desktop operating system it largely comes down to the likes of MidnightBSD and GhostBSD providing good out-of-the-box setups. As for GhostBSD, they are reaffirming their commitment to using TrueOS/FreeBSD and MATE as their official desktop.

The project reaffirmed on Wednesday that they are sticking to their TrueOS with FreeBSD 12-STABLE base while being a "slow-moving rolling release' that will eventually migrate to TrueOS with FreeBSD 13-STABLE after it is available.

  • Google Ejects Open-Source WireGuard From Android Play Store Over Donation Link In App

    Apparently Google doesn't appreciate donation links/buttons within programs found on the Google Play Store even when it's one of the main sources of revenue for open-source programs. WireGuard has been reportedly dropped over this according to WireGuard lead developer Jason Donenfeld.

    After waiting days for Google to review the latest version of their secure VPN tunnel application, it was approved and then removed and delisted -- including older versions of WireGuard. The reversal comes on the basis of violating their "payments policy". Of course, Google would much prefer payments be routed through them so they can take their cut...

  • [Older] Sourcehut makes BSD software better

    Every day, Sourcehut runs continuous integration for FreeBSD and OpenBSD for dozens of projects, and believe it or not, some of them don’t even use Sourcehut for distribution! Improving the BSD software ecosystem is important to us, and as such our platform is designed to embrace the environment around it, rather than building a new walled garden. This makes it easy for existing software projects to plug into our CI infastructure, and many BSD projects take advantage of this to improve their software.

    Some of this software is foundational stuff, and their improvements trickle down to the entire BSD ecosystem. Let’s highlight a few great projects that take advantage of our BSD offerings.

  • Security updates for Thursday

    Security updates have been issued by Arch Linux (sudo), Debian (libsdl1.2 and libsdl2), Mageia (e2fsprogs, kernel, libpcap and tcpdump, nmap, and sudo), openSUSE (GraphicsMagick and sudo), Oracle (java-1.8.0-openjdk, java-11-openjdk, jss, and kernel), Red Hat (java-1.8.0-openjdk and java-11-openjdk), Scientific Linux (jss), SUSE (gcc7 and libreoffice), and Ubuntu (leading to a double-free, libsdl1.2, and tiff).

  • Grasp Docker networking basics with these commands and tips

    Docker communicates over network addresses and ports. Within Docker hosts, this occurs with host or bridge networking.

    With host networking, the Docker host sends all communications via named pipes. This method, however, can pose a security risk, as all traffic flows across the same set of containers with no segregation.

    The other approach from Docker, bridge networking, provides an internal network that connects to the external one.

    Use the docker network ls command to see a list of available networks. This command should return results that look similar to the output in Figure 1.

The hackathon helped the project members build connections and strengthen bonds.

  • FOSSCOMM 2019 aftermath

    FOSSCOMM (Free and Open Source Software Communities Meeting) is a Greek conference aiming at free-software and open-source enthusiasts, developers, and communities. This year was held at Lamia from October 11 to October 13.

    It is a tradition for me to attend to this conference. Usually I have presentations and of course booths to inform the attendees about the projects I represent.

    This year the structure of the conference was kind of different. Usually the conference starts on Friday with "beer event". Now it started with registration and a presentation. Personally I made my plan to leave from Thessaloniki by bus. It took me about 4 hours on the road. So when I arrived, I went to my hotel and then waited for Pantelis to go to the University and setup our booths.

  • Empowering Generations of Digital Natives

    Technology is changing faster each year. Digital literacy can vary between ages but there are lots of ways different generations can work together and empower each as digital citizens.

    No matter whether you’re a parent or caregiver, teacher or mentor, it’s hard to know the best way to teach younger generations the skills needed to be an excellent digital citizen. If you’re not confident about your own tech skills, you may wonder how you can help younger generations become savvy digital citizens. But using technology responsibly is about more than just technical skills. By collaborating across generations, you can also strengthen all your family members’ skills, and offer a shared understanding of what the internet can provide and how to use it to help your neighborhoods and wider society.

  • How to Verify Smart Contracts on Etherscan

    You have your smart contract written, tested, and deployed. However, customers aren’t willing to do business with you unless they know the contract’s source code. After all, it could be set up in a way that’s not in their interest.

    Thankfully, Etherscan offers a neat tool that allows you to verify smart contracts so interested parties can see the source code and verify for themselves that everything is as it should be.

    While the process is simple, there are intricacies that might cause problems, especially to people not very familiar with Ethereum and the Solidity programming language.

  • Ethical Open Source: Is the world ready?

    Given its incredible popularity in the marketplace, there is no question that many software developers (and their respective companies) today see great value in using software that is subject to open source licenses. Users focus on the advantages to be had by gaining access, usually at no or minimal charge, to the software’s source code and to the thriving open source community supporting such projects.

    Powered by a worldwide community supporting the code base, open source code is generally perceived to be more reliable, robust and flexible than so-called proprietary software, with increased transparency leading to better code stability, faster bug fixes, and more frequent updates and enhancements.

    Historically the question of ethics and open source software (OSS) has mainly focussed on the goal of obtaining and guaranteeing certain “software freedoms,” namely the freedom to use, study, share and modify the software (as exemplified by the Free Software Definition and copyleft licenses such as the GPL family), and to ensure that derivative works were distributed under the same license terms to end “predatory vendor lock-in.”

  • New SystemView Verification Tool from SEGGER is Compatible with Windows, Linux, and macOS
  • 5 steps for an easy JDK 13 install on Ubuntu
  • Basic Data Types in Python 3: Strings
  • Excellent Free Books to Learn VimL

    VimL is a powerful scripting language of the Vim editor. You can use this dynamic, imperative language to design new tools, automate tasks, and redefine existing features of Vim. At an entry level, writing VimL consists of editing the vimrc file. Users can mould Vim to their personal preferences. But the language offers so much more; writing complete plugins that transform the editor. Learning VimL also helps improve your efficiency in every day editing.

    VimL supports many common language features: variables, control structures, built-in functions, user-defined functions, expressions first-class strings, high-level data structures (lists and dictionaries), terminal and file I/O, regex pattern matching, exceptions, as well as an integrated debugger. Vim’s runtime features are written in VimL.

  • Google Releases Bazel 1.0 Build System With Faster Build Performance

    Bazel is Google's preferred build system used by many of their own software projects. Bazel is focused on providing automated testing and release processes while supporting "language and platform diversity" and other features catered towards their workflow. Bazel 1.0 comes at a time when many open-source projects have recently been switching to Meson+Ninja as the popular build system these days for its fast build times and great multi-platform build support. Bazel also still has to compete with the likes of CMake and many others.

  • Bazel Reaches 1.0 Milestone!

    Bazel was born of Google's own needs for highly scalable builds. When we open sourced Bazel back in 2015, we hoped that Bazel could fulfill similar needs in the software development industry. A growing list of Bazel users attests to the widespread demand for scalable, reproducible, and multi-lingual builds. Bazel helps Google be more open too: several large Google open source projects, such as Angular and TensorFlow, use Bazel. Users have reported 3x test time reductions and 10x faster build speeds after switching to Bazel.

Red Hat OpenShift 4.2: Kubernetes for the hybrid-cloud developer

Filed under
Red Hat

I've said before that Red Hat wants OpenShift to be the hybrid-cloud platform. Now, with its latest release, Red Hat OpenShift 4.2, Red Hat is doubling down on this plan.

As Ashesh Badani, Red Hat's senior vice president of Cloud Platforms, said in a statement:

"We continue to prioritize making the next generation of enterprise open-source technologies like Kubernetes even more accessible to developers while also keeping administrator priorities in balance. With these goals in mind, OpenShift 4.2 delivers on features to help customers accelerate application development and delivery."

In OpenShift 4.2, Red Hat makes it easier than ever to set up and manage Kubernetes -- the heart of the new hybrid-cloud model. With it, developers can focus on building enterprise applications without deep Kubernetes expertise.

AMD EPYC vs. Intel Xeon Cascadelake With Facebook's RocksDB Database

Filed under
Graphics/Benchmarks

Following the benchmarks earlier this month looking at PostgreSQL 12.0 on AMD EPYC Rome versus Intel Xeon Cascade Lake there was interest from Phoronix readers in wondering how well Rome is doing for other modern enterprise database workloads. One of those workloads that was recently added to the Phoronix Test Suite / OpenBenchmarking.org is Facebook's RocksDB, the company's embedded database that is forked from Google LevelDB. With RocksDB being designed to exploit many CPU cores and modern SSD storage, here are some benchmarks looking at how the Xeon Platinum 8280 stacks up against various new AMD EPYC 7002 series processors.

RocksDB is a key-value embedded database solution that Facebook has been working on since 2012 in taking Google's LevelDB to the next level of performance on modern CPU/SSD servers. RocksDB is in turn also used by companies like LinkedIn, Airbnb, Pinterest, Rakuten, Uber, and others.

With RocksDB having its own performance-focused built-in benchmarks, it makes for some interesting performance comparisons on these server CPUs given its growing presence in the enterprise. Those unfamiliar with RocksDB can learn more at RocksDB.org.

    The upcoming release of Arch's Pacman 5.2 is bringing support for compressing packages with Zstd which ultimately will provide faster package installs on Arch Linux.

    Similar to other Linux distributions beginning to make use of Facebook's Zstd (Zstandard) compression algorithm for faster compression/decompression of packages, Arch Linux is doing the same. Their findings mirror that of others in allowing faster compression/decompression performance with a similar compression ratio for binaries to that of XZ.

GNOME Shell Development Updates

GNOME
  • GNOME Shell + Mutter Begin Landing Graphene Integration

    Graphene is a lightweight library that has been in development by GNOME's Emmanuele Bassi. Graphene -- not to be confused with several other software projects sharing similar names -- is intended as a very lightweight library providing graphics types and their relative API while avoiding any windowing system bits and other functionality with this layer just focused on providing speedy vector operations. Graphene has fast paths for SSE2, ARM NEON, GCC Vector extensions, and other optimizations for optimally dealing with graphic data types like matrices, vectors and points.

    [...]

    With part 1, various geometry/point/rectangle/vector Clutter objects are replaced with Graphene code. Ultimately this should provide for better performance around various graphic data type operations while also cleaning up some of GNOME's low-level code in the process. This initial integration is now in place for the initial GNOME 3.35/3.36 series though expect more Graphene improvements to come now that the initial support and dependency are in place.

    AMD open-source developer Marek Olšák on Wednesday released libdrm 2.4.100 as the newest feature update to this Mesa DRM library.

    On the AMD front there are a number of RAS tests added, a new amdgpu_cs_query_reset_state2 interface, and other expanded AMDGPU test coverage.

  • AMDGPU GFX9+ Format Modifiers Being Worked On For Better DCC Handling

    RADV Vulkan driver developer Bas Nieuwenhuizen of Google has ventured into kernel space in working on format modifiers support for Vega/GFX9 and newer.

    This DRM format modifiers support for GFX9+ is being worked on for helping to evaluate when delta color compression (DCC) can be used and any other requirements around that DCC handling. Bas explained, "This is particularly useful to determine if we can use DCC, and whether we need an extra display compatible DCC metadata plane."

  • Free software support for virtual and augmented reality

    A talk at the recent X.Org Developers Conference in Montréal, Canada looked at support for "XR" in free software. XR is an umbrella term that includes both virtual reality (VR) and augmented reality (AR). In the talk, Joey Ferwerda and Christoph Haag from Collabora gave an overview of XR and the Monado project that provides support for those types of applications.

    Ferwerda started by defining the term "HMD", which predates VR and AR. It is a head-mounted display, which basically means "taking a screen and some sensors and duct-taping it to your face". All of the devices that are being used for XR are HMDs. They typically include some kind of tracking system to determine the position and orientation of the HMD itself. Multiple different technologies, including inertial measurement units (IMUs), photodiodes, lasers, and cameras, are used to do the tracking depending on the device and its use case.

    AR is intended to augment the real world with extra information; the user sees the real world around them, but various kinds of status and additional data is tagged to objects or locations in their view of the world. AR is a rather over-hyped technology these days, he said. The general idea is that users would wear glasses that would augment their view in some fashion, but, unfortunately, what most people think of as AR is Pokémon Go.

    VR uses two screens, one for each eye, to create a 3D world that the user inhabits and can interact with in some fashion. Instead of seeing the real world, the user sees a completely separate world. There are two words that are often used to describe the feel of VR, he said: "presence" and "immersion". That means users are aware of themselves as being part of the VR environment.

    XR encompasses both. Ferwerda said that he is not really sure what the "X" stands for; he has heard "cross reality" and "mixed reality" for XR. Haag said that "extended reality" was another definition that he had heard.

  • Intel Now Aiming For Gallium3D OpenGL Default For Mesa 20.0

    For the better part of two years now Intel has been working on this new "Iris" Gallium3D driver for supporting Broadwell "Gen8" graphics and newer as the eventual replacement to their long-standing i965 classic driver. With Tiger Lake "Gen12" Xe graphics, it's in fact Iris Gallium3D only. In our testing of Broadwell through the *lakes, this Gallium3D driver has been working out terrific on Mesa 19.2 stable and Mesa 19.3 development. But it looks like Intel is going to play it safe and punt the default change-over to next quarter's Mesa 20.0 cycle.

Embedded system cross-development with Ubuntu Core

Filed under
Ubuntu

There are fundamental differences between developing general-purpose software applications and making software for embedded systems. Embedded systems software runs on resource-constrained hardware, in contrast to general-purpose server or client applications that run on more capable hardware. For this reason, embedded system software is not directly developed on the electronic board it will run on – referred to as the target. It is rather developed on a computer – the host – that has a higher computational capacity than the target board.
