CPUFreq Scaling Tests With AMD's Kaveri On Linux 3.16

Filed under
Linux

Besides looking at how the raw performance was impacted by using the different scaling governors, the AC system power consumption was monitored and the performance-per-Watt also measured using the Phoronix Test Suite as was the CPU frequency states. This testing is very straight forward so let's get right to the results.

Microsoft

There used to be a time when GNU/Linux was kept under mysterious 1% market share. Today mobile Linux Android owns over 85% of the market share leaving the once market leading iOS behind. But its not a tragedy for iOS that it’s market share has shrunk, the real tragedy is for Microsoft whose Windows Phone market share has gone down to mere 2.5%; just 1.5% ahead of what Linux used to have on desktops.

Linux

This is part 3 in a series aimed at making it easier for people to choose the right Linux distribution for them.

In the first part of the series I listed a number of the best desktop environments and the Linux distributions that use them.

In the second part I listed the 5 Linux distributions I would recommend for modern hardware based on their ease of use.

This article lists the 5 Linux distributions I would recommend for older computers based on their ease of use. Note that there will be a further article for the best distributions to run on ancient hardware.

We are moving our production GNOME desktop to new physical hardware. After some discussions and reviewing work loads, we decided for now to stay with GNOME 2. The older server was cloned and was finally moved to the new hardware. The server is 100% solid state drives with 80 hyperthreaded cores. This increased capacity was needed for the next project:

Reiser4 Now Available for the 3.15 kernel, so what?

Filed under
Linux
Reiser

A recent announcement was made stating that the Reiser4 file system, successor to the ReiserFS, was ported to the 3.15 Linux kernel. Following the 2006 conviction and incarceration of the mastermind that original conceived this project (Hans Reiser), a few dedicated developers continued supporting this file system despite the odds stacked against them. In the last decade, the Linux kernel has seen newer file systems, most of which are integrated into the mainline kernel tree (i.e. btrfs, ext4, etc.). Reiser4 was rejected for inclusion some time back, and most of its developers moved on (one or more of which are currently working on btrfs).

Raspberry Pi arrives on PC/104… sort of

Crowd Supply is hosting a “Pi/104” carrier for the RPi Compute Module 3 featuring PC/104 OneBank expansion, a 40-pin RPi header, and -25 to 80°C support. Here’s something we haven’t seen before. Developer Adam Parker has launched a stackable PC/104 form factor carrier board on Crowd Supply designed to work with the Linux-driven Raspberry Pi Compute Module 3. The industrial-targeted carrier provides -25 to 80°C support and an 8-36V input with screw terminal connector. Read more

  • Blockchain Moves Beyond its 'Moonshot' Phase
  • Some reading
    I've complained previously about disliking benchmarking. More generally, I'm not really a fan of performance analysis. I always feel like I get stuck at coming up with an approach to "it's going slower, why" beyond the basics. I watched a video of Brendan Gregg's talk from kernel recipes, and ended up going down the black hole1 of reading his well written blog. He does a fantastic job of explaining performance analysis concepts as well as the practical tools to do the analysis. He wrote a book several years ago and I happily ordered it. The book explains how to apply the USE method to performance problems across the system. This was helpful to me because it provides a way to generate a list of things to check and how to check them. It addresses the "stuck" feeling I get when dealing with performance problems. The book also provides a good high level overview of operating systems concepts. I'm always looking for references for people who are interested in kernels but don't know where to start and I think this book could fill a certain niche. Even if this book has been out for several years now, I was very excited to discover it.
  • Introducing container-diff, a tool for quickly comparing container images
    The Google Container Tools team originally built container-diff, a new project to help uncover differences between container images, to aid our own development with containers. We think it can be useful for anyone building containerized software, so we’re excited to release it as open source to the development community.

    It’s not that there aren’t already a lot of time tracker apps but my conscience wouldn’t let me sleep if I didn’t tell you about NATTT. So grab your cup of whatever you’re probably drinking as we delve into this app a little. NATTT is an acronym for “Not Another Time Tracking Tool”; a free and multi-platform app with which you can keep track of your work and how much you have spent at it.

  • Compact DAQ systems offer a choice of 12- or 16-bit I/Os
    Advantech’s Linux-ready “MIC-1810” and “MIC-1816” DAQ computers offer 12- and 16-bit analog I/O, respectively, plus 24x DIOs, Intel CPUs, and 4x USB ports. Advantech’s MIC-1810 and MIC-1816 are digital acquisition computers that run Linux or Windows 7/8/10 on Intel 3rd Gen “Ivy Bridge” processors. If the aging CPU is a turn-off, keep in mind that many DAQ applications don’t require that much processing power, and perhaps Advantech’s “entry-level” label for the systems extends to the price, as well. The 165 x 130 x 59mm, DIN-rail mountable systems should also prove useful for environments with limited space.

Security: New Release of HardenedBSD, Windows Leaks Details of Windows Back Doors

  • Kaspersky blames NSA hack on infected Microsoft software
    Embattled computer security firm Kaspersky Lab said Thursday that malware-infected Microsoft Office software and not its own was to blame for the hacking theft of top-secret US intelligence materials. Adding tantalizing new details to the cyber-espionage mystery that has rocked the US intelligence community, Kaspersky also said there was a China link to the hack.
  • Investigation Report for the September 2014 Equation malware detection incident in the US
    In early October, a story was published by the Wall Street Journal alleging Kaspersky Lab software was used to siphon classified data from an NSA employee’s home computer system. Given that Kaspersky Lab has been at the forefront of fighting cyberespionage and cybercriminal activities on the Internet for over 20 years now, these allegations were treated very seriously. To assist any independent investigators and all the people who have been asking us questions whether those allegations were true, we decided to conduct an internal investigation to attempt to answer a few questions we had related to the article and some others that followed it:
  • Kaspersky: Clumsy NSA leak snoop's PC was packed with malware
    Kaspersky Lab, the US government's least favorite computer security outfit, has published its full technical report into claims Russian intelligence used its antivirus tools to steal NSA secrets. Last month, anonymous sources alleged that in 2015, an NSA engineer took home a big bunch of the agency's cyber-weapons to work on them on his home Windows PC, which was running the Russian biz's antimalware software – kind of a compliment when you think about it. The classified exploit code and associated documents on the personal system were then slurped by Kremlin spies via his copy of Kaspersky antivirus, it was claimed.
