  • Google says Pixel 6, 6 Pro coming this year with custom AI acceleration

    Google today said the latest iteration of its Android smartphones, the Pixel 6 and Pixel 6 Pro, are coming this fall.

    So far the internet advertising goliath has only offered a glimpse of the gear: no official specifications have been released.

    The Pixel 6 and 6 Pro look like your standard high-end 6.ish-inch aluminium-framed smartphones. The Pixel 6 Pro is expected to sport a 6.7" 120Hz screen, 5G connectivity, and a raised bank of cameras on the back that includes a wide-angle main sensor and one with a 4X optical-zoom telephoto lens.

    Problems, questions, comments?
    Please let us know: http://lttng.org/contact
    
    You can also report bugs at: https://bugs.lttng.org/projects
    
    ==== SETTING UP LTTng 2.x ====
    
    LTTng 2.x features a unified trace-control client "lttng" to control both kernel tracing (through lttng-modules) and userspace tracing (through UST). The client itself is shipped in the "lttng-tools" package.
    
    To install the toolchain:
    $ sudo apt-add-repository ppa:lttng/ppa
    $ sudo apt-get update
    $ sudo apt-get install lttng-tools lttng-modules-dkms babeltrace
    
    You may also want to install:
    liblttng-ust-dev: To compile applications instrumented with UST tracepoints
    python3-babeltrace: Python bindings for babeltrace
    
    Once the modules are installed correctly, you can start tracing right away. No need to reboot!
    
    You can now refer to http://lttng.org/quickstart to use the kernel or userspace tracers.
    
    ==== Daily build packages ====
    
    If you prefer living on the edge, you can use the latest development versions in the daily PPA: https://launchpad.net/~lttng/+archive/daily
    
  • ernel Tracing With LTTng On Ubuntu Maverick

    "Linux Tracing Toolkit (LTTng) provides high-performance kernel tracing for Linux. This is the killer app for system level debugging and performance tuning. It's now easier than ever to install, with packages released for Ubuntu Maverick. The short introduction to kernel tracing shows how to interpret a simple kernel trace and relate it to strace. I would like to ask Slashdot readers what they would expect as features for a kernel tracing analysis tool, because I'm starting my PhD on this topic and looking for ideas. Also, I wonder why LTTng is not mainline yet. Will Linus Torvalds see the light in 2011?"

  • Seems the Valve Steam Deck has been impressing people with some hands-on time | GamingOnLinux

    Recently a bunch of people from other sites went to Valve's offices for some hands-on time with the Steam Deck and it seems the overall impression was pretty positive.

    Like a lot of others, we're in the waiting line for whenever our unit ships early next year so we're currently going by whatever info Valve give out and by what other lucky people think after testing. Obviously Valve are going with the top few PC gaming sites / video content creators to make as big a splash as possible, they're certainly doing massively better on pushing it this time compared with the Steam Machines. With that in mind, we do have a few videos to show from others.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
