  • How to Deploy GraphQL Application Using Node.js on EC2 Server – Linux Hint

    GraphQL, also known as Graph Query Language, established and maintained by Facebook, is a query language used for APIs. It is built using JavaScript, Scala, Java, and Ruby programming languages. Its basic purpose is to ask for the data from server to client.GraphQL aggregates the data from different sources. Aggregation is the process of filtering data on the server side and then sending the filtered data to the client. Without aggregation, we send all the data to the client, and then the data is filtered at the client-side. This makes the system slow, and we can improve the efficiency of an API by using GraphQL. Here we will learn to deploy a simple GraphQL application using node.js on an EC2 server.

Void Linux Has Been Working To Deliver Great POWER Support

Void Linux, a rolling-release distribution we have covered before that is known for its XBPS package manager and interesting design decisions like using the Runit init system and supporting the Musl C library, has recently been working on enhancing its POWER CPU architecture support. Daniel Kolesa who serves as the primary maintainer for the POWER port of Void Linux spoke at FOSDEM 2021 earlier this month on their improvements to benefit IBM POWER / OpenPOWER hardware. Void Linux for POWER has been working on 32-bit little endian support to complement the existing POWER 64-bit little endian support as well as already supporting POWER 32-bit and 64-bit in big endian mode. Void Linux has also been carrying patches for LibreSSL to offer faster crypto performance on POWER, getting the likes of Google Chromium running on POWER in their archive, supporting Electron applications on POWER, and also getting good AMD Radeon graphics driver support working on POWER.

  • Broadcom VK Accelerator Driver, More Intel ACRN Code Arrives For Linux 5.12 - Phoronix

    Greg Kroah-Hartman this week sent in "the large set of char/misc/whatever driver subsystem updates", which as usual -- given it's a catch-all area of kernel drivers not fitting well into other subsystems -- there is an interesting mix of additions. Linux 5.12 still isn't moving forward with any "accelerator" subsystem for the likes of the Habana Labs driver and other accelerators / offload cards, even with Linux 5.12 bringing the Broadcom VK accelerator driver, so for now the char/misc area of the kernel continues to expand.

  • Mesa Flips On OpenGL Threading For Valheim To Deliver Better Performance - Phoronix

    For those enjoying the Valheim, the new survival/sandbox game that has been an incredible success and sold more than four millions of copies so far while being a low-budget indie game, Mesa should be providing better performance when using its OpenGL renderer. Valheim is powered by the Unity game engine and is natively supported on Linux. Initially the focus was on the OpenGL rendering support while the game is now running out Vulkan support. But for those sticking to OpenGL usage, Mesa Git is performing better thanks to enabling OpenGL threading.

  • Simos Xenitellis: How to run a Windows virtual machine on LXD on Linux

    LXD is a hypervisor to run both system containers (a la LXC) and virtual machines (a la QEMU) on Linux distributions. System containers are lightweight because they are based solely on the Linux kernel for their virtualization features, and support Linux guests only. However, virtual machines can run other operating systems. In this post, we see how to run Windows in a LXD virtual machine. The benefit with running Windows through LXD is that you are using the familiar LXD workflow and takes away some of the the complexity from the other ways of running a VM (like virt-manager). The content of this tutorial came from https://discuss.linuxcontainers.org/t/running-virtual-machines-with-lxd-4-0/7519 Look towards the end of the thread where Stéphane Graber describes how to simplify the process compared to the instructions at the top of that thread. The prerequisite is that you have LXD configured and running.

  • Open source database migration guide: How to transition

    Open source database migration typically involves more than just a database. It is more accurately described as a database ecosystem transition, which can include multiple independent projects for management, monitoring, tuning, connection pooling, high availability and third-party support. Beyond the database ecosystem, application integration with the database may be impacted as well.

    The appeal of open source databases, particularly for smaller non-mission-critical systems, has led to increased adoption and market popularity.

  • Set up your own Slack-like chat system on Linux

    Zulip’s 3.0 release back in July saw over 100 people contribute from all over the world. It also brought support for Ubuntu 20.04, so we fired up our server to see just how easy it is to install and if it could restore our faith in chat. We’re pleased to say it’s super easy and we strongly recommend adding it to your server, too. [...] The two key bits of terminology to grasp are streams and topics. Streams are a broader hierarchy and can be thought of as separate chatrooms.  Different members of your team can be members of different streams, and streams can be made private so that only certain people can see them. Within a stream every message has its own topic and conversations will appear threaded thusly, rather like email subject lines. However, unlike email subject lines you can’t be lazy and have a blank thread. This tiny bit of extra effort is what enables everything to be so nicely organised, so that you can enjoy hassle-free open source messaging whether in real time or asynchronously, perhaps catching up on messages from your colleagues in other time zones.
