Review: 5 memory debuggers for Linux coding

Friday 20th of November 2015 09:31:24 PM
As a programmer, I'm aware that I tend to make mistakes -- and why not? Even programmers are human. Some errors are detected during code compilation, while others get caught during software testing. However, a category of error exists that usually does not get detected at either of these stages and that may cause the software to behave unexpectedly -- or worse, terminate prematurely.

Performance monitoring with Monitorix 3.8.0 on Ubuntu 15.10

Friday 20th of November 2015 08:34:13 PM
This tutorial will show the installation and configuration of Monitorix on Ubuntu 15.10 (Wiley Werewolf). 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.

Parrots Bebop 2: smaller, faster, longer-lasting, Linux-fortified

Friday 20th of November 2015 03:33:36 AM
Like all of Parrot’s previous drone models, including the original Bebop, the Bebop 2 runs Parrot’s open source Linux flight stack. In San Francisco, Parrot unveiled a smaller, faster, longer lasting version of its Linux-based Bebop drone, helping to solidify its dominance in the mid-range consumer market. One of the key new features is an emergency cutoff that instantly kills the quadrotor motors when a blade hits an obstacle. The increasing focus on safety was also demonstrated this week when 3DR (Solo) and DJI (Phantom) announced similar new technology to make it easier for their customers to avoid restricted airspace (see farther below).

Systemd — unit dependencies and order

Welcome back to our continuing series on systemd features. As you’ve guessed from our previous articles, systemd brings more power and flexibility to service startup and management. One of the most important changes in systemd from legacy SysVinit is how it starts up units. You may have heard from casual users that systemd starts everything together. Some people believe this is true, and that’s why the system starts faster. But the reality is not quite that simple. Let’s look a little more deeply at how systemd understands unit relationships.

  • New HPCG Benchmark List Goes Beyond LINPACK to Compare Supercomputers
    The High Performance Conjugate Gradients (HPCG) Benchmark list was announced this week at SC15. This is the fourth list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems.

  • Distro hopping: feeling good with my time on LXLE
    Well the time has come to officially switch off from LXLE. This time around however I find myself in a weird spot. I’ve honestly struggled with LXLE; not in using the distribution itself but rather coming up with things to write about it. That isn’t to say that LXLE is bad by any stretch of the imagination, in fact it is quite good, it’s just that once you get used to the light weight desktop environment (DE) there is a perfectly capable “heavy weight” distribution underneath. What I mean by this is that once you get used to the DE and it fades into the background you’re left with a perfectly functional distribution that could just as easily have been Ubuntu or Linux Mint or Fedora or {insert your favourite one here}.
  • Netrunner 17 'Horizon' is here -- download the Kubuntu-based Linux distro now
    About a week ago, the Netrunner team released an update to its rolling release operating system. Based on Arch/Manjaro, I advised Linux beginners to steer clear, and instead opt for the Kubuntu-based variant. There are a couple of reasons for this. For one, the Ubuntu community is arguably friendlier and better for newbies -- there are a ton of instructions and .deb files available too. More importantly, however, the rolling release could be less stable overall.
