  • 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.

  • The Apache Cassandra Project Releases Apache® Cassandra™ v4.0, the Fastest, Most Scalable and Secure Cassandra Yet

    The Apache Cassandra Project released today v4.0 of Apache® Cassandra™, the Open Source, highly performant, distributed Big Data database management platform.

    "A long time coming, Cassandra 4.0 is the most thoroughly tested Cassandra yet," said Nate McCall, Vice President of Apache Cassandra. "The latest version is faster, more scalable, and bolstered with enterprise security features, ready-for-production with unprecedented scale in the Cloud."

Apache Cassandra 4.0 Big Data Database Management System

  • Apache Cassandra 4.0 Big Data Database Management System Released

    pache Cassandra 4.0 is finally available as the latest major feature release to this widely-used NoSQL database management system.

    Cassandra 4.0 further juices the performance with scaling operations being up to five times faster, 25% faster throughput for reads and writes, and also lower latency work.

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.

LibreOffice 8.0 New tabbed interface layout available

Muttakin Rizal ( Rizal Muttaqin ), one of the designers LibreOffice office suite, has published in his blog, the user interface possible development plan LibreOffice 8.0. The most notable innovation is the built-in support for tabs, through which you can quickly switch between different documents, similar to how switching between sites is carried out in modern browsers. If necessary, each tab can be unpinned in the form of a separate window, or vice versa, convert the window into a tab. It is also possible to collapse all tabs into a drop-down list accessible by pressing the “^” button. The header also shows a LibreOffice button to launch the initial interface, which was previously shown when starting or closing all documents, to open a file, visually evaluate recently opened documents, or create a new document based on a template.

  • How to Completely Uninstall Google Chrome From Ubuntu

    So, you managed to install Google Chrome on Ubuntu. It is the most popular web browser in the world, after all. But perhaps you dislike Google products for the heavy tracking and data mining they employ on its users. You decided to opt for other web browsers on Ubuntu, perhaps a non-Chromium browser. Now that you are no longer using it, it would be wise to remove Google Chrome from Ubuntu.

  • How to uninstall applications in GNU / Linux - itsfoss.net

    Either because the latest program we installed does not convince us, or because we are determined to ‘lighten up’ our equipment, it is important to know how we can uninstall software (or rather, using the correct terminology, ‘packages’) from our Linux system . However, one thing we should know about Linux is that there is not just one way to uninstall (or install, since we are) packages , but multiple. In the first place, it will differ according to the distribution we are using, and secondly according to how we prefer to carry out this task using graphical tools or the command line terminal.

  • How To Install Apache Airflow on Ubuntu 20.04 - idroot

  • 13 Top Command In Linux (Monitor Linux Server Processes) | LinuxTeck

    In this article, we will learn how to monitor running processes on Linux. The Linux OS offers several commands that can be used to monitor a running process, but for checking dynamic real-time processes, we can use a command called 'TOP. This tool enables System Administrators to determine how fully real-time processes are utilized by their current system. With every Linux distribution, the 'top' utility comes pre-installed. We can utilize the interactive command to see the summary of the current system stats, and also customize the list of processes, threads, and many other features. This guide shows you how to use the top with various options to view all the current system activities. System administrators will be able to manage system resources as well as optimize their hardware utilization by analyzing uptime, CPU usage, memory utilization, swap space usage, load average, and all the other processes that are running on their system to ascertain how much real-time processing is being used.
