  • End of Support for Fairphone 1: Some Unanswered Questions

    I previously followed the goings-on at Fairphone a lot more closely than I have done recently, so after having mentioned the obsolescence risks of the first model in an earlier article, it was interesting to discover a Fairphone blog post explaining why the company will no longer support the Fairphone 1. Some of the reasons given are understandable: they went to market with an existing design, focusing instead on minimising the use of conflict minerals; as a result various parts are no longer manufactured or available; the manufacturer they used even stopped producing phones altogether!

    A mention of batteries is made in the article, and in community reaction to the announcement, a lot of concern has been expressed about how long the batteries will be good for, whether any kind of replacements might be found, and so on. With today’s bewildering proliferation of batteries of different shapes and sizes, often sealed into devices for guaranteed obsolescence, we are surely storing up a great deal of trouble for the future in this realm. But that is a topic for another time.

  • Python security transparency

    As Steve Dower noted in his lightning talk at the 2017 Python Language Summit, Python itself can be considered a security vulnerability—because of its power, its presence on a target system is a boon to attackers. Now, Dower is trying to address parts of that problem with a Python Enhancement Proposal (PEP) that would enable system administrators and others to detect when Python is being used for a nefarious purpose by increasing the "security transparency" of the language. It is not a solution that truly thwarts an attacker's ability to use Python in an unauthorized way, but will make it easier for administrators to detect, and eventually disable, those kinds of attacks.

  • OpenStack Charms 17.08 release!

    The OpenStack Charms team is pleased to announce that the 17.08 release of the OpenStack Charms is now available from jujucharms.com!

    In addition to 204 bug fixes across the charms and support for OpenStack Pike, this release includes a new charm for Gnocchi, support for Neutron internal DNS, Percona Cluster performance tuning and much more.

  • Go Serverless with new PiCluster 2.2

    I am pleased to introduce the new release of PiCluster! In PiCluster 2.2, there is now support to deploy functions! With this new feature, applications can spin up containers themselves and retrieve data from the PiCluster server. Let’s explore how this works.

    When a function is finished running, the container is automatically deleted and the output is stored on the server. When the application requests the data from the server, the data is removed as well.


  • Plasma publictransport rewrite – Part II

    Last time we heard the publictransport applet was being re-written was almost a year back now. Since then, it has indeed gone through some sorts of rewrite, but at the Randa meetings, 2017, this has taken a whole new course.

  • Spam filtering with Rspamd

    Running one's own mail system on the Internet has become an increasingly difficult thing to do, to the point that many people don't bother, even if they have the necessary skills. Among the challenges is spam; without effective spam filtering, an email account will quickly drown under a deluge of vile offers, phishing attempts, malware, and alternative facts. Many of us turn to SpamAssassin for this task, but it's not the only alternative; Rspamd is increasingly worth considering in this role. Your editor gave Rspamd a spin to get a sense for whether switching would be a good thing to do.

    SpamAssassin is a highly effective tool; its developers could be forgiven for thinking that they have solved the spam problem and can move on. Which is good, because they would appear to have concluded exactly that. The "latest news" on the project's page reveals that the last release was 3.4.1, which came out in April 2015. Stability in a core communications tool is good but, still, it is worth asking whether there is really nothing more to be done in the area of spam filtering.

  • Finding driver bugs with DR. CHECKER

    Drivers are a consistent source of kernel bugs, at least partly due to less review, but also because drivers are typically harder for tools to analyze. A team from the University of California, Santa Barbara has set out to change that with a static-analysis tool called DR. CHECKER. In a paper [PDF] presented at the recent 26th USENIX Security Symposium, the team introduced the tool and the results of running it on nine production Linux kernels. Those results were rather encouraging: "it correctly identified 158 critical zero-day bugs with an overall precision of 78%".

Kernel: LWN Linux Articles (Now Free), Testers Wanted

TuxMachines - Sat, 2017-09-16 23:33
  • CPU frequency governors and remote callbacks

    The kernel's CPU-frequency ("cpufreq") governors are charged with picking an operating frequency for each processor that minimizes power use while maintaining an adequate level of performance as determined by the current policy. These governors normally run locally, with each CPU handling its own frequency management. The 4.14 kernel release, though, will enable the CPU-frequency governors to control the frequency of any CPU in the system if the architecture permits, a change that should improve the performance of the system overall.

    For a long time, the cpufreq governors used the kernel's timer infrastructure to run at a regular interval and sample CPU utilization. That approach had its shortcomings; the biggest one was that the cpufreq governors were running in a reactive mode, choosing the next frequency based on the load pattern in the previous sampling period. There is, of course, no guarantee that the same load pattern will continue after the frequency is changed. Additionally, there was no coordination between the cpufreq governors and the task scheduler. It would be far better if the cpufreq governors were proactive and, working with the scheduler, could choose a frequency that suits the load that the system is going to have in the next sampling period.

  • A last-minute MMU notifier change

    One does not normally expect to see significant changes to an important internal memory-management mechanism in the time between the ‑rc7 prepatch and the final release for a development cycle, but that is exactly what happened just before 4.13 was released. A regression involving the memory-management unit (MMU) notifier mechanism briefly threatened to delay this release, but a last-minute scramble kept 4.13 on schedule and also resulted in a cleanup of that mechanism. This seems like a good time to look at a mechanism that Linus Torvalds called "a badly designed mistake" and how it was made to be a bit less mistaken.

What is the status of Linux on cameras?

Reddit - Sat, 2017-09-16 22:51

I've been searching the internet for the use of Linux on various cameras but found absolutely nothing so far.

Are there any companies making Linux OS for cameras(other than Android)? Any cameras at all(action cams, movie cams, astronomy cams, medical research cameras)? Any upcoming projects and their status?

Linux GPU maximum??

Reddit - Sat, 2017-09-16 22:26

Hey everyone,

So I currently have a mining rig running 8gpus of the same architecture and that is the maximum for Windows 10 unless I mix it up with amd gpus.

It was mentioned briefly in the article I was reading that if you want more than 8 than to switch to Linux.

I currently do have more than 8 gpus and would like to run them all on my 13gpus btc board. I searched but could not find, does anyone know the limit of gpus that Linux can support?

I have never used Linux, never even seen Linux before. So it is brand new to me.

Any help is appreciated.

Thank you

Suggestions for a system monitoring tool that can run on embedded Linux machines and has a web frontend

Reddit - Sat, 2017-09-16 20:52

I wrote my own daemon that is controlled over websockets. However, it has no web frontend of its own. This is intentional. This daemon is intended to be ran on embedded devices, and I figure that there are already existing system monitoring tools with their web frontend where you can set up the network adapters, WiFi credentials, and can check out information about temperature, voltage, memory usage, CPU usage etc. So, the idea is that I'd simply extend such a web frontend to incorporate widgets for configuring my daemon.

However, I only mostly find large network management systems such as Zabbix or Zenoss. Ideally, such a system monitoring software would have a web frontend that looks like the web interface of OpenWRT or DD-WRT for example. But, so far, I haven't found any that (a) can be ran on embedded, Rasperry Pi/i.MX/Dragonboard-class hardware without using a significant amount of resources and/or having a lot of complexity of which 90% will end up unused (I do not need to watch the whole network, for example), (b) has a web frontend already provided (otherwise it would be pointless for my purpose), and (c) allows for relatively easy extension of said web frontend.

Any suggestions?

Linux RAID Performance On NVMe M.2 SSDs

Phoronix - Sat, 2017-09-16 18:15
For boosting the I/O performance of the AMD EPYC 7601 Tyan server I decided to play around with a Linux RAID setup this weekend using two NVMe M.2 SSDs. This is our first time running some Linux RAID benchmarks of NVMe M.2 SSDs and for this comparison were tests of EXT4 and F2FS with MDADM soft RAID as well as with Btrfs using its built-in native RAID capabilities for some interesting weekend benchmarks.
