Reddit: Why does spwaning a firefox session escape the parent process that spawned it?

10 hours 7 sec ago

For example I'm running a desktop under i3. Every time I spawn a shell or any other process through the i3 menu, htop lists i3 as the parent process.

However, doing the same with firefox resorts in firefox parenting itself directly under /sbin/init (escaping my login shell). Why is this? And how does it do this?

Reddit: Is Linux Real Time enough?

10 hours 12 min ago

I work with a team that is considering porting from Green Hills OS to Linux, but the concern is that it may not be real time enough. To me this seems silly, but I ask you, the experts. If we're running a AT91SAM9 processor, and require about 20ms latency on responding to messages, are we going to have trouble with Linux? Thanks!

LXer: Performance monitoring with Monitorix on Ubuntu 16.04

10 hours 52 min ago
This tutorial shows the installation and configuration of Monitorix on Ubuntu 16.04 (Xenial Xerus). Monitorix is a free, lightweight, open source monitoring tool designed to monitor as many services and system resources as possible on servers and desktops. It consists mainly of two programs: a collector, called Monitorix, which is a Perl daemon that is started automatically as a system service, and a CGI script called monitorix.cgi. Since 3.0 version Monitorix includes its own HTTP server built in, so you aren't forced to install a third-party web server to use it.

11 hours 55 min ago
A bar graph is a plot which visualizes data values using proportional-size bars. Bar charts are useful when you want to compare multiple items among different categories. As you can imagine, they are much more effective than a table of numerical data.

LXer: Appreciating the full power of open

12 hours 58 min ago
Last year was a big year for open source. As Wired put it, 2015 was the year open source software "went nuclear". More people than ever seem to realize the power of open—not just as a programming methodology, but as a better way to accomplish just about anything.read more

  • Linux Foundation launches badge program to boost open source security

    The Linux Foundation has released the first round of CII Best Practices badges as part of a program designed to improve the quality and security of open-source software.

    Announced on Tuesday, the non-profit said the Core Infrastructure Initiative (CII), a project which brings tech firms, developers and stakeholders together to create best practice specifications and improve the security of critical open-source projects, has now entered a new stage with the issue of CII badges to a select number of open-source software.

  • Free Badge Program Signals What Open Source Projects Meet Criteria for Security, Quality and Stability
  • How to Conduct Internal Penetration Testing

    The best way to establish how vulnerable your network is to a hacker attack is to subject it to a penetration test carried out by outside experts. (You must get a qualified third party to help with penetration testing, of course, and eSecurity Planet recently published an article on finding the right penetration testing company.)

  • SSH for Fun and Profit

    In May last year, a new attack on the Diffie Hellman algorithm was released, called Logjam. At the time, I was working on a security team, so it was our responsiblity to check that none of our servers would be affected. We ran through our TLS config and decided it was safe, but also needed to check that our SSH config was too. That confused me – where in SSH is Diffie Hellman? In fact, come to think of it, how does SSH work at all? As a fun side project, I decided to answer that question by writing a very basic SSH client of my own.

  • Dutch government organisations not ready for open data requests

    Dutch government organisations are generally unable to process requests under the new 'Law for re-use of government information' in a timely and correct manner. According to inventories made by the Open State Foundation and Open Archives, government at all levels took months to decide on the requests, had problems providing the information in an open and machine-readable format, and failed to forward requests that should be handled by other organisations.

  • Hungarian Post charging high costs to frustrate right to public information

    The issue was brought before Péterfalvi Attila, President of the National Authority for Data Protection and Freedom of Information, by Tóth Bertalan, Deputy Faction Leader for the Hungarian Socialist Party (MSZP). Tóth argued that citizens are restricted in exercising their right of access to public information if an agency asks that much money for its data.

Debian, Devuan, and Ubuntu

  • My Free Software Activities in April 2016
    I handled a new LTS sponsor that wanted to see wheezy keep supporting armel and armhf. This was not part of our initial plans (set during last Debconf) and I thus mailed all teams that were impacted if we were to collectively decide that it was OK to support those architectures. While I was hoping to get a clear answer rather quickly, it turns out that we never managed to get an answer to the question from all parties. Instead the discussion drifted on the more general topic of how we handle sponsorship/funding in the LTS project.
  • Initial Planning For Ubuntu 16.10 Today At UOS
    Beyond the announcement that Ubuntu 16.10 won't ship with Mir and Unity 8 by default, many other items were discussed for the Ubuntu 16.10 release due out in October.
  • Ubuntu 16.10 Isn't Going To Use Mir / Unity 8 By Default
    Well, another setback for Unity 8 and Mir. Kicking off the Ubuntu Online Summit for Ubuntu 16.10, it's been confirmed that the Unity 8 desktop and Mir display server will not be the default for the desktop spin. Similar to the current situation with existing Ubuntu releases, Unity 8 and Mir will be available as an opt-in feature for users wanting to upgrade their desktop, but Unity 7 and the faithful X.Org Server is planned to be the default for Ubuntu 16.10 Yakkety Yak.
  • Devuan Beta Release
    After two years in development, a beta release of the Devuan distro has made it into the world (Devuan is a registered trademark of the Dyne.org foundation). Devuan is a very Debian-ish distro. In fact, it basically is Debian, with one notable absence. Devuan doesn't use systemd. In fact, that's its main claim to fame. Devuan was created to offer an alternative to Debian fans who were alienated by the controversial switch to systemd.
