  • Systemd 243 RC1 Brings Its PStore Service, Zen2/RdRand Workaround & More

    Lennart Poettering has made available the first release candidate of the upcoming systemd 243 update. Systemd 243 is a big one in seeing more than 1,700 commits since the April release of systemd 242. 

  • Radeon RADV Vulkan Driver Adds Navi Wave32 Support For Compute Shaders

    Thanks to Valve's open-source driver developer Samuel Pitoiset, there is now experimental support for using Wave32 support on Navi graphics cards for compute shaders. 

    Navi/RDNA brings support for single-cycle issue Wave32 execution as an alternative to Wave64 for better efficiency. Just over a week ago the initial patches landed adding Wave32 support to RadeonSI for their OpenGL driver while now Samuel has tackled the initial implementation in the RADV driver. 

  • Mining Monero Cryptocurrency On The Open-Source POWER9 Raptor Blackbird

    Unlike my POWER8 server, the Blackbird cannot measure its own system power consumption (only the processor's), so I used a simple watt meter to take measurements. When off, with just the BMC on, the system took so little power my meter could not measure it. It kept showing 0 W, so presumably it's under a Watt. At idle, 55 W.

    For each SMT mode, I tried six thread options. The SMT scaling is as expected, at SMT1 there are eight threads, and performance drops after; at SMT2 16 threads, and a corresponding drop after. The "more resources for each thread" effect is also slightly visible, with SMT1 having the highest result at eight mining threads.
    In SMT4, the efficiency scaling is quite nice, showing that a mere eight-core is not even close to the bottleneck here.

  • Another Step in Automating the Pageload Recordings

    In a previous article, Kimberly Sereduck told us about Updates to Warm Page Load Tests and how we are continuously working to make our tests more representative of real user behavior. Besides that, we are working on automating the process of recording the website’s page load.

  • Practicing lean data is a journey that can start anywhere - Open Policy & Advocacy

    “It’s not about the destination, but about the journey.” I’m sure data and privacy are the furthest from your mind when you hear this popular saying. However, after a year of virtually sharing Mozilla’s Lean Data Practices (LDP), I’ve realized this quote perfectly describes privacy, LDP, and the process that stakeholders work through as they apply the principles to their projects, products, and policies. [...] There is an appetite to understand how we as consumers can hold companies accountable. One of the biggest surprises for me came when I would field questions at the end of a presentation, and people would ask about their rights as consumers and how they can hold companies accountable. For example, people wanted to understand their rights and recourse options if companies contacted them without permission, didn’t honor their unsubscribe requests, or did something else frustrating. I teach LDP for individuals to apply it in a business context, but we are all also consumers and customers. LDP can help us better understand how our own data should be handled and improve our understanding of what organizations are doing. We can then remember how we feel about certain situations and then ensure we are doing things in a more consumer-friendly way within our organizations. Lean Data Practices is a journey. For many there won’t be an ultimate destination because it is an iterative process. If you try to apply all the principles across your entire organization at once, you will find yourself overwhelmed and likely unsuccessful. To maximize your chance of success, my advice — which is the same advice we give when we present — is to just start somewhere. Choose one aspect of your business and focus on that, one pillar at a time. Once you’ve successfully applied the principles, go to a different business unit and do the same. Remember to review and adapt as products and business needs (or data!) change as well. You may likely never reach your destination, but you will see your company improve in its practices along the way.

  • Tor vs. VPN: Is One Better than the Other?

    Tor and VPN have unique ways to ensure user privacy on the Internet. They’re fundamentally very different yet have many similar aims. Due to the overlap in features, you may be weighing the pros and cons of using one over the other. Or maybe they can be treated equally but with separate purposes. This guide digs into everything you need to know about which software should be used for more Internet anonymity.

  • New Alpha Release: Tor Browser 11.5a2 (Windows, macOS, Linux)

    Tor Browser 11.5a2 is now available from the Tor Browser download page and also from our distribution directory.

    This version includes important security updates to Firefox.

Intel Core i9 12900K P-State Governor Performance On Linux Review

Since Intel's Alder Lake launch one of the test requests to come in a few times has been about the Intel P-State CPU frequency scaling driver and how its performance differs with the various governor choices available for altering the CPU frequency scaling behavior. Now that Linux 5.16 stable is out and running in good shape on Alder Lake, here are some Core i9 12900K benchmarks looking at various CPU frequency scaling choices and their impact on raw performance as well as CPU thermals and power consumption. With Alder Lake having seen fixes in Linux 5.16 as well as ADL-S graphics being enabled by default on this new kernel, it's a good target for carrying out the P-State testing. The main reader inquiry has obviously been about how how well these new Intel hybrid processors perform if moving from P-State "powersave" as is often the default governor on most distributions to instead using the "performance" governor that tends to keep the CPU in its higher performance states more aggressively than powersave.
