OSS Leftovers: Using Open Source to Drive Automation, Arcan and OpenBSD, RISC-V

  • Using Open Source to Drive Automation
    While the IT side of telecom organizations has a long history of using open source technology, the networking side has traditionally relied more on commercial solutions that adhere to industry standards. And for good reasons. Although industry standards development organizations have a bad rep for death by PowerPoint and interminable meetings, they have delivered robust, global standards that meet the stringent quality requirements of the communications industry and enable a degree of interoperability that avoids vendor lock-in while still promoting innovation.
  • Towards Secure System Graphics: Arcan and OpenBSD

    Let me preface this by saying that this is a (very) long and medium-rare technical article about the security considerations and minutiae of porting (most of) the Arcan ecosystem to work under OpenBSD. The main point of this article is not so much flirting with the OpenBSD crowd or adding further noise to software engineering topics, but to go through the special considerations that had to be taken, as notes to anyone else that decides to go down this overgrown and lonesome trail, or are curious about some less than obvious differences between how these things “work” on Linux vs. other parts of the world.

  • RISC-V SiFive Freedom Unleahsed 540 SoC / HiFive Unleashed Board Added To Coreboot
    Landing today within the Coreboot Git tree is support for the RISC-V based SiFive Freedom Unleashed 540 System-on-a-Chip and SiFive's Unleashed mainboard making use of this SoC built around the royalty-free and open processor ISA. The SiFive Freedom Unleashed 540 is considered to be the first RISC-V SoC capable of running Linux and with just over 400 lines of new code added to the existing RISC-V code in Coreboot, that SoC should now have its initial support in place. This SoC runs in a 4+1 multi-core configuration at speeds up to 1.5GHz with four cores being the RV64GC application cores and the fifth being the RV64IMAC management core. There is a 2MB L2 cache, support for 64-bit DDR4 with ECC, and Gigabit Ethernet backed by this SoC manufactured on a 28nm processor.

R and Mozilla Development

  • A Good Front End for R
    R is the de facto statistical package in the Open Source world. It's also quickly becoming the default data-analysis tool in many scientific disciplines. R's core design includes a central processing engine that runs your code, with a very simple interface to the outside world. This basic interface means it's been easy to build graphical interfaces that wrap the core portion of R, so lots of options exist that you can use as a GUI. In this article, I look at one of the available GUIs: RStudio. RStudio is a commercial program, with a free community version, available for Linux, Mac OSX and Windows, so your data analysis work should port easily regardless of environment. For Linux, you can install the main RStudio package from the download page. From there, you can download RPM files for Red Hat-based distributions or DEB files for Debian-based distributions, then use either rpm or dpkg to do the installation.

Best open source Microsoft Office alternatives

Microsoft Office remains the go-to productivity package for many businesses, with the obvious exception to that being Google G Suite users. But high costs and a growing number of irrelevant features means that increasingly, professionals are looking for more options. Luckily, there are a number of options out there which are completely free. Here, we take a look at the best open source software packages that provide a successful replacement to Microsoft Office. And don’t worry, most are also compatible with Microsoft Office documents, meaning the transition to new software needn’t be messy. Read more
