Iconic Linux debate sparks an open source career

Thursday 29th of October 2015 01:07:08 AM
In 1992 I started working for the Tandem Computers subsidiary in Sao Paulo, Brazil. I was part of the team that started Tandem's operations in Brazil, and at the time I was the one and only techie in the group. Tandem was later acquired by Compaq, and now it's the NonStop division inside HP.At the time, Tandem manufactured and sold a high availability Unix System, the NonStop Integrity.

Raspberry Pi answers: Are my hamsters lazy or super athletes?

Wednesday 28th of October 2015 08:23:08 PM
Last year, I brought two new Roborovski hamster pups into our home. They looked identical at the time, so I named them both Hamtaro. (Fast forward the 1.5 years I've owned them, and one has grown significantly tubbier than the other... So I've nicknamed her Hamtaro Grande.)read more

Performance of inline assembly: An analysis based on the computation of Fibonacci sequence

Wednesday 28th of October 2015 07:26:20 PM
Using the Fibonacci sequence computation as an example, this article analyzes the speed advantage of an inline assembly implementation in comparison to the performance of other programming techniques such as the recursive algorithm, the dynamic programming implementation, the iterative approach, and the optimized matrix power algorithm. The target audience is software engineers interested in further accelerating the execution of their applications by handcrafting the assembler codes for the most performance-critical sections.

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.

  • AMD Radeon Software Crimson Edition Is A Letdown On Linux

  • 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. The first HPCG list was announced at ISC’14 a year and a half ago, containing only 15 entries and the SC’14 list had 25.

  • 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.

  • Tumbleweed install for November
    For this month, I installed Tumbleweed on my laptop. I had installed Leap 42.1 to overwrite my previous Tumbleweed install on that laptop. This computer uses legacy booting. I gave Tumbleweed a 40G partition, which I formatted as “ext4”. I also allowed it to use the swap and home file systems from my encrypted LVM on that computer.
