TuxMachines: Linux Action Show ends after 10-year run

Monday 27th of March 2017 03:56:12 PM

This past Sunday, Jupiter Broadcasting announced the Linux Action Show—one of the longest-running podcasts in the Linux world, which has aired almost continuously since June 10, 2006—is coming to an end and closing down production.

Over a decade. That is a seriously good run for any show—podcast, TV, radio or otherwise. When I and my co-host created the Linux Action Show (typically abbreviated as LAS) nearly 11 years ago, we had no idea it would last this long. Nor did we have any idea of how far it would grow.

Reddit: Process startup testing

Monday 27th of March 2017 03:54:18 PM

I'm seeking a method for running tests on our custom Linux OS, developed using the Yocto Project, that will help us gauge process startup time. Preferably this will be done through forking.

Does anyone have any recommendations on open source test platforms that can help test this?

We've been looking through phoronix Test Suite though there seems to not be any of use there.

Reddit: Tool to monitor process network connections?

Monday 27th of March 2017 03:41:29 PM

Short version: I am looking for a linux utility similar to the windows tcpview utility from sysinternals.

Long version:

I have an odd problem with an application. We have a commercial application that replicates its proprietary database across a network connection. This is running on two suse enterprise servers. The servers each have 10Gb connections to their local switches, but the switches only a have a 1Gb link between them (this is across datacenters). They connect at layer 2 (they are on the same subnet).

The replication processes consistently transfer around 200GB of data, then errors out. After sending numerous debug logs and wireshark packet captures to the vendor, their opinion is "network error". They base this off the numerous dropped packets and retransmission shown in the packet captures. I can't get them to understand that you'd expect to see lots of dropped packets with a 1Gb link in between two 10Gb links.

iperf3 shows a continuous 900Mb or better throughput between the two systems. I can successfully sftp a 250GB file both ways. No other systems that operate across the two datacenters are having problems, including backups which send a considerable amount data across every day (Yes, I have tried the replication with backups quiesced) .

I am looking for some sort of utility that can monitor the vendor processes and show me how they are opening sockets to each other (what options are used), and whether the socket is erroring out, or if the application is just getting confused somehow and closing the socket. I am hoping that the vendor is doing something goofy with tcp options in an attempt to boost performance.

TuxMachines: Samsung Z4 gets WiFi Certified with Tizen 3.0 onboard, Launching soon

Monday 27th of March 2017 03:40:18 PM

Today, the next Tizen smartphone, which should be the named the Samsung Z4, has received its WiFi certification (certification ID: WFA70348) – Model number SM-Z400F/DS with firmware Z400F.001 on the 2.4Ghz band.

WiFi certification is usually one of the last steps before a mobile device gets released and means a launch is coming real soon as we have already seen the Z4 make its debut appearance at the FCC. For the previous model, the Samsung Z2, we saw it get WIFi certified on 7 July and then launched on 23 August, a mere 6 weeks.

TuxMachines: Kernel Space: Linux, Graphics

Monday 27th of March 2017 03:28:25 PM
  • Mux Controller Subsystem Proposed For Linux 4.12

    A new subsystem has been proposed for staging in the Linux 4.12 kernel.

    Peter Rosin has requested Greg KH pull in the mux controller subsystem for the Linux 4.12 kernel. He explained of this new subsystem, "This adds a new mux controller subsystem with an interface for accessing mux controllers, along with two drivers providing the interface (gpio and adg792) and two consumers (iio and i2c). This is done in such a way that several consumers can independently access the same mux controller if one controller controls several multiplexers, thus allowing sharing."

Reddit: Save a tux in enterprise, I need your advices !

Monday 27th of March 2017 01:58:31 PM

Hello ! :)

We are a little (~20 people) association. We use Linux every day at work. All our SI and workstations are on Linux.

Our enterprise will merge with another who work ONLY on Microsoft solutions (Windows and Office).

The IT guy in this enterprise just sent a mail to my boss, trying to explain why it’s a shame to use Linux on workstations.

I just need advices and « fact checking » from the reddit community to find good arguments for my boss again this kind of lettre. (Prices seems to be good as we are an association and we have special prices).

I’ll translate here his letter (sorry for my English) :

Here is our justification for the choice of Windows in ou futur structure :

Fact : Vulnerabilities ( : * 4354 with the keyword « windows » * 3451 with the keyword « linux » Exemple of recent vulnerabilities : * Badtunnel for Windows (2016.03) * TCP vulnerability in the linux Kernel (2016/07) Desktop market share : * 90 % for Windows * 2 % for Linux Full market share (mobile, etc. included) : * 20 % for Windows (declining) * 80 % for Linux (growing) Hackers concern (hacking as « pirate interest») * Stable for Windows * Growing for Linux Ease of developing a malware : * Same for the two plateform. Application market : * Very high, big concern from software editors * Low, not enough concern from software editors

Link with our situation : We both have professionnal software who needs Windows. In your actual configuration (Linux), it forces your structure to : - Use an emulated (KVM) windows on some of your Linux workstation (you have to pay a licence for this virtual machine). You have to pay the electric consumption too, linked to the emulation of a guest system. I saw that you had to install a physical workstation for Adobe pack, which cost you approximatly 150$ of electricity a year.

Windows solution cost 35$ / month / user, including windows updates, Office and antivirus (less if we use a free antivirus). The fact that viruses are not on linux is a myth. We also find malwares on linux (more on servers and mobile devices (Android) ).

With the use of linux, we will highly complicate our information system. I know that it’s a IT concern, but the time spent on this kind of administration will greatly increase time needed for IT. Extra cost needed will go far over amount saved on software licences.

With all this arguments, adopt a linux strategy for our workstation will force us to constantly accomodate our choices for software solutions. We also have to adapt all our work tools for our linux environment.

The purpose of an information system isn’t to constraint of a particulare software because of the operating system. The operating system must adapt himself to the tools we choose.

Our big concern is : The computer system must adapt himself to the user. The user would not have to adapt his habits because of the constaint of his operating system. To resume : Windows have a better adaptation to user, which is not the case for Linux on workstation.

Citations : « You have to keep in mind that the more an IT system is complicated, the more it is hard to adminitrate, despite the competences of people who manage it.

This way, the foundation of the information system could be call into question. submitted by /u/boulate

LXer: A Python script for fixing smart quotes in text

In case you don't know what this means, typographic quotes (for example, “ and ”) are sometimes referred to as curly quotes, rather than the incorrect versions on your typewriter (i.e., ").read more

Why OpenStack is the wrong cloud for Red Hat to be building its future on

Just because one can make money from OpenStack doesn't mean one should. Red Hat, on its recent earnings call, gladly assumed the title of "Red Hat of OpenStack," meaning the "vendor that does certification and confidently allow[s] both hardware and software vendors to participate in the ecosystem." In a similar vein, I've called OpenStack Red Hat's "Linux moment," a chance to productize the growing cloud movement. Read more
