  • Micron Working On NVMe SSD Abrupt Shutdown Support For Linux - Phoronix

    The NVMe specification provides for an abrupt shutdown mode over the normal/safe shutdown command if needing to quickly get the NVMe solid-state storage ready for powering off as quickly as possible. Currently the Linux kernel isn't making use of the NVMe abrupt shutdown command but a proposal by Micron is looking to begin its usage. 

    A patch set sent out on Monday by a Micron engineer wires up the abrupt shutdown support for NVMe SSD. The initial use-case is over platforms with a very limited back-up power supply and if knowing a power loss is imminent, to perform the abrupt shutdown of the NVMe SSD.

  • Linux as a computational storage panacea? - Open Source Insider

    Linux is widely agreed to be key to the onward development of computational storage.

    As we have noted before, computational storage enables a software and hardware system to offload and alleviate constraints on existing compute, memory and storage.

    So given this proposition, how should software engineers identify, target and architect specific elements of the total processing workload to reside closer to computational storage disks (CSDs) and what role can Linux play in this process?

    The open ecosystem of open source Linux has been lauded as a key facilitating technology to creating the secure containerisation principles that express key elements of computational storage.

Apache Cassandra 4.0 advances open source database

  • Apache Cassandra 4.0 advances open source database

    After three years of development, the open source Apache Cassandra 4.0 database is now generally available.

    Apache Cassandra is a distributed NoSQL database that was originally developed at Facebook. In recent years, the open source technology has received support from multiple vendors that have also built commercial services for the database.

    Cloud service providers that have Apache Cassandra database-as-a-service offerings include AWS and Microsoft, which entered the Cassandra segment in March 2021. Beyond the big public cloud providers, DataStax provides a database-as-a-service that is based on Cassandra. Other vendors that provide Cassandra as a service include Aiven, which raised $100 million in March, and Instaclustr.

  • Apache Cassandra 4.0 finally arrives

    Well, that took a while. Well over a year ago the Apache Software Foundation announced the beta of Cassandra 4.0. Developers were eager to get their hands on this, the most popular of the NoSQL databases. Alas, it took longer than many had hoped. Then at the 11th hour, a nasty bug was found, which further delayed Cassandra's release for a few days. But, at long last Apache Cassandra 4.0 is here and ready to tear into your petabytes of data.

Apache Cassandra 4.0 Features Increased Speed And Scalability

  • Apache Cassandra 4.0 Features Increased Speed And Scalability

    Nearly six years on from the release of Apache Cassandra 3.0, the community behind the popular open-source distributed database has announced the release of v4.0 of Apache Cassandra. Patrick McFadin, VP of Developer Relations at DataStax, and Ben Bromhead, CTO of Instaclustr, join TFiR Newsroom to talk more about the release.

    The first issue to be addressed is the importance Cassandra holds in the modern world. McFadin starts off by talking about what workloads Cassandra is focused on, i.e. websites and mobile applications. McFadin says, “When you use a mobile app on your phone, you’re probably using Cassandra.”

Cassandra 4.0 finally out of the gates after being delayed...

  • Cassandra 4.0 finally out of the gates after being delayed for last-minute bug swat

    After an Apple engineer called an 11th-hour halt to the release, Cassandra 4.0 has finally launched flaunting newfound stability, speed and consistency, according to the open-source project's users and contributors.

    The code for wide-column database – which has been popular as a distributed system with users including Apple, Instagram and eBay – officially went live today, around six years after 3.0's debut.

    The developer community is said to have invested the time in wanting to make this the most stable release of the NoSQL system, and ship with no known bugs.

    Speaking to The Register in the run-up to launch, Vinay Chella, engineer and cloud data architect at Netflix, said the new model for streaming data between nodes made it between four and five times faster, accelerating the recovery from failed nodes, and reducing costs.

Günther Wagner: GNOME Builder 41 Highlights

Builder now maintains a private Flatpak installation to install SDKs and SDK extensions that are not available in the user’s Flatpak installation. This means Builder will no longer add flathub or gnome-nightly to your user’s Flatpak installation. Builder now uses an out-of-process Flatpak helper (gnome-builder-flatpak) to vastly improve its ability to track and resolve SDK extensions. This will improve the situation for applications requiring Rust, LLVM, and others going forward. You can update your SDKs and dependencies together using the “Update Dependencies” button in the build popover. More information can be found in Christian’s blog post. Read more

Games: Steam Deck, FUTEX2, and Anti-Cheat Support

  • Steam Deck, Linux and Mac Get Easy Anti-Cheat Support

    Epic Games has just released an update to its Easy Anti-Cheat software that will add support for the Steam Deck, as well as Linux and macOS operating systems. According to an Epic blog post today, the new update is now available to developers for free and is designed to work with Wine and Steam's Proton compatibility layer to ensure all platforms under Linux get full anti-cheat support. This is great news for Linux Gamers and for the new Steam Deck, since the anti-cheat services were previously locked to Windows operating systems. Even though the games could be fully functional in a compatibility environment such as Proton or Wine. Now, more platforms have the capability to run all multiplayer games with Epic's popular anti-cheat software, as long as developers enable Linux and Mac support. This is especially important for Valve's Steam Deck, which counts on its SteamOS being able to run the entire Steam library. Obviously, lacking anti-cheat support could have been a major problem for the new console.

  • Valve's Steam Deck supports dual boot and booting from a microSD card - Liliputing

    The Valve Steam Deck is expected to begin shipping in December to customers who pre-orders the handheld gaming computer for $399 or more. But ever since introducing the Linux-powered PC with a custom AMD processor this summer, Valve has been getting a lot of questions.

  • Updated "FUTEX2" futex_waitv Patches Posted To Address Latest Feedback - Phoronix

    The promising FUTEX2 work focused on improving the Linux performance for running Windows games via Wine/Proton by extending futex to wait on multiple locks is still moving forward. Last month the work was revised in simpler form by just focusing on the new "futex_waitv" system call and postpone additional improvements planned around variable-sized futexes, NUMA-awareness, and more. That additional work will come later while the immediate focus is on the "futex_waitv" system call to address the needs of Wine/Proton by better matching Windows' WaitForMultipleObjects behavior with more efficient emulation.

  • Epic Games announce full Easy Anti-Cheat support for Linux including Wine & Proton | GamingOnLinux

    Today, Easy Anti-Cheat from Epic Games / Epic Online Services has officially announced a full expansion for Linux including native builds and Wine + Proton. This is big for Linux Gaming and the Steam Deck. For those who don't know, Epic Games owns Easy Anti-Cheat and earlier this year they made it free for all developers making Windows games. Today this has been expanded to fully support developers doing native Linux games (and macOS too). Not only that, this is the big one we've been waiting for — they've also expanded Easy Anti-Cheat support officially for the Wine and Steam Play Proton compatibility layers.

  • Epic Games makes Easy Anti Cheat available for Linux, paving the way for Steam Deck | Windows Central

    One of the big flies in the Steam Deck ointment has always been how anti-cheat software will be handled. The truth is that a lot of the popular Windows games that can't be played on Linux through Steam's Proton Compatibility layer, or through WINE, are because of anti-cheat software. The first big step forward has just happened, though, right as game developers are starting to receive their Steam Deck dev kits. Epic Games, owner of Easy Anti Cheat, has announced that the software is now compatible with Linux, including WINE and Proton, as well as macOS. And all for the low price of free.
