Solus Operating System interview

Filed under
OS
Interviews

This is where it starts to get a bit complicated… So to start from the end, EvolveOS and SolusOS are the same thing – we had to rebrand. I was living in the UK myself until last year, when I came back home [to Ireland]. So the problem I had is that I wanted to, ironically, protect the project from patent trolls, and in the process I had to apply for a trademark to protect the project. On April Fool’s day last year, of all days, I had a letter come through saying that I was going to be threatened with legal action, and I thought it might be about the name Evolve. It actually wasn’t – it was about the use of OS! Apparently the Ordnance Survey took a dislike to my using of it, as I was informed that the trademark was held by the Secretary of State – so I wasn’t allowed to use my name because of a map maker! When I was trying to explain it to people they were like, ‘Well what about Chrome OS? What about iOS?’ When I was in the UK at the time, Google was heavily invested with a lot of start-up companies and giving out Chromebooks and that, and that was through a partnership deal with the government. Apple had just furnished the House of Lords and the House of Commons with iPads. I imagine that the Secretary of State was quite happy to ignore the fact that they were using OS in their names… But the small fry like me? So I said, ‘Okay, we’ll change it.’ We went through a week trying to come up with a name, but in the end I decided to go back to the old name, which is where SolusOS comes in.

KDE Interview Questions - Riccardo Iaconelli

Filed under
KDE
Interviews

Currently, I am the maintainer of WikiToLearn, working on all the parts of the project where is needed, but mostly on the promotion/networking side. I deliver talks and presentations, and I am in charge of getting in touch with excellent academic institutions that could partner with us.
In the past... well, I have been doing thousands of things! Smile I have been a core developer of Plasma, writing the first plasmoids, a core developer and a designer of Oxygen (working on the theme, window decoration, cursor theme, icons, wallpapers...) and many more things (from kdelibs to games to PIM). Probably the major work (outside these big projects) I am most proud of the complete UI redesign (and implementation) of Amarok in QML. It was sexy, but unfortunately it was never released, due to a decision of the maintainers.

Linux Foundation Certified Engineer: Francisco Tsao

Filed under
Linux
Interviews

n 1998, I got bored by the MS-DOS/Windows world. I was studying Civil Engineering, but in the neighborhood of my school was the Faculty of Computer Science, and I had some friends there. I began hearing about GNU/Linux from them. I bought a new computer and spent a weekend installing Debian 2.0 and, after a week, I had a graphical interface running on the box. The same year, I joined GPUL the Coruña Linux Users Group, where I learned a lot about tech and Free Software philosophy. Richard Stallman’s "The Right To Read" changed my life definitely. I'm very proud of my LUG (one that is still very much alive). In fact, this year we hosted the Akademy!

Interviews
Security

This is a gross over-simplification, but multiple containers on a host is just the next logical step from multiple virtual machines on a host. Because those containers are tightly controlled by the kernel namespaced, Security Enhanced Linux, Linux kernel capabilities, and the like, you can be assured that the risk is minimal.

Interviews
OSS

Schuyler St. Leger is one of the superheroes of the maker movement. He's a speaker, young maker, and was featured in Make magazine. His famous presentation, Why I love my 3-D Printer has received over 300,000 views on YouTube.

Schuyler is keynoting at SCaLE 14x, where he'll talk about open source radio and how it's impacting the world around us. We're surrounded by radios in smartphones, tablets, laptops, and Wi-Fi access points, yet we often fail to realize their ubiquitous presence. The airwaves are a fantastic space for exploration, but where do we begin? Open source radio combined with open hardware is a rich space for exploration and experimentation.

Using strace to track system calls in Linux

Filed under
Linux
Interviews

Strace is a tool used to intercept system calls from your application to the Linux kernel. I find strace is invaluable for system administrators for two main reasons.

First off, we do not always have the source code of an application available, but we may still need to know what an application is doing. This can be anything from which files are opened, how much memory is being allocated or even why an application is crashing repeatedly.
Secondly, even if we do have the code, being a system administrator doesn't imply being a developer. We may not know how to follow the code. I find that looking at system calls as opposed to lines of code is a bit more descriptive

OSS

I have been involved with Linux and open source since the mid-1990s, and Scylla is a natural progression for open source to move up the stack and provide more value for some of the most demanding companies out there. The problems involved in running a resilient database are some of the hardest and most valuable in IT today.

3 smart GIMP tricks

Filed under
GNU
Interviews

Honestly, I think a lot of the people claiming GIMP isn't as good as Photoshop are people who have invested a lot in learning Photoshop and want an excuse not to learn a new and different tool. If the GIMP team spent much time trying to make everything just like Photoshop, they'd never have time to implement great new features.

It's true there are some nice features Photoshop has that GIMP doesn't. Some are being addressed for GIMP 3.0, like high-color images. A lot of people will be very happy to see that. Other features, like non-destructive editing and CMYK, are still wish-list items that will have to wait until later.

Hardware With Linux

  • Raspberry Pi's new computer for industrial applications goes on sale
    The new Raspberry Pi single-board computer is smaller and cheaper than the last, but its makers aren’t expecting the same rush of buyers that previous models have seen. The Raspberry Pi Compute Module 3 will be more of a “slow burn,” than last year’s Raspberry Pi 3, its creator Eben Upton predicted. That’s because it’s designed not for school and home use but for industrial applications. To make use of it, buyers will first need to design a product with a slot on the circuit board to accommodate it and that, he said, will take time.
  • ZeroPhone — An Open Source, Dirt Cheap, Linux-powered Smartphone Is Here
    ZeroPhone is an open source smartphone that’s powered by Raspberry Pi Zero. It runs on Linux and you can make one for yourself using parts worth $50. One can use it to make calls and SMS, run apps, and pentesting. Soon, phone’s crowdfunding is also expected to go live.
  • MSI X99A RAIDER Plays Fine With Linux
    This shouldn't be a big surprise though given the Intel X99 chipset is now rather mature and in the past I've successfully tested the MSI X99A WORKSTATION and X99S SLI PLUS motherboards on Linux. The X99A RAIDER is lower cost than these other MSI X99 motherboards I've tested, which led me in its direction, and then sticking with MSI due to the success with these other boards and MSI being a supporter of Phoronix and encouraging our Linux hardware testing compared to some other vendors.
  • First 3.5-inch Kaby Lake SBC reaches market
    Axiomtek’s 3.5-inch CAPA500 SBC taps LGA1151-ready CPUs from Intel’s 7th and 6th Generations, and offers PCIe, dual GbE, and optional “ZIO” expansion. Axiomtek’s CAPA500 is the first 3.5-inch form-factor SBC that we’ve seen that supports Intel’s latest 7th Generation “Kaby Lake” processors. Kaby Lake is similar enough to the 6th Gen “Skylake” family, sharing 14nm fabrication, Intel Gen 9 Graphics, and other features, to enable the CAPA500 to support both 7th and 6th Gen Core i7/i5/i3 CPUs as long as they use an LGA1151 socket. Advantech’s Kaby Lake based AIMB-205 Mini-ITX board supports the same socket. The CAPA500 ships with an Intel H110 chipset, and a Q170 is optional.

Leftovers: Ubuntu and Debian

According to the post on the Debian website by Debian Project, the new version is 8.7. This is the seventh update to the Debian eight distribution, and the update primarily focuses on fixing bugs and security problems. This update also includes some adjustments to fix serious problems present in the previous version.
  • Freexian’s report about Debian Long Term Support, December 2016
    The number of sponsored hours did not increase but a new silver sponsor is in the process of joining. We are only missing another silver sponsor (or two to four bronze sponsors) to reach our objective of funding the equivalent of a full time position.
  • APK, images and other stuff.
    Also, I was pleased to see F-droid Verification Server as a sign of F-droid progress on reproducible builds effort - I hope these changes to diffoscope will help them!
  • Linux Mint 18.1 "Serena" KDE Gets a Beta Release, Ships with KDE Plasma 5.8 LTS
    After landing on the official download channels a few days ago, the Beta version of the upcoming Linux Mint 18.1 "Serena" KDE Edition operating system got today, January 16, 2017, an official announcement. The KDE Edition is the last in the new Linux Mint 18.1 "Serena" stable series to be published, and it was delayed a little bit because Clement Lefebvre and his team wanted it to ship with latest KDE Plasma 5.8 LTS desktop environment from the Kubuntu Backports PPA repository.

Top Ubuntu Editing Apps: Image, Audio, Video

It's been my experience that most people aren't aware of the scope of creative software available for Ubuntu. The reason for this is complicated, but I suspect it mostly comes down to the functional availability provided by each application title for the Linux desktop. In this article, I'm going to give you an introduction to some of the best creative software applications for Ubuntu (and other Linux distros). Read more

Leftovers: OSS and Sharing

  • Google's open-source Draco promises to squeeze richer 3D worlds into the web, gaming, and VR
    Google has published a set of open source libraries that should improve the storage and transmission of 3D graphics, which could help deliver more detailed 3D apps.
  • Why every business should consider an open source point of sale system
    Point of sale (POS) systems have come a long way from the days of simple cash registers that rang up purchases. Today, POS systems can be all-in-one solutions that include payment processing, inventory management, marketing tools, and more. Retailers can receive daily reports on their cash flow and labor costs, often from a mobile device. The POS is the lifeblood of a business, and that means you need to choose one carefully. There are a ton of options out there, but if you want to save money, adapt to changing business needs, and keep up with technological advances, you would be wise to consider an open source system. An open source POS, where the source code is exposed for your use, offers significant advantages over a proprietary system that keeps its code rigidly under wraps.
  • Can academic faculty members teach with Wikipedia?
    Since 2010, 29,000 students have completed the Wiki Ed program. They have added 25 million words to Wikipedia, or the equivalent of 85,000 printed pages of content. This is 66% of the total words in the last print edition of Encyclopedia Britannica. When Wiki Ed students are most active, they are contributing 10% of all the content being added to underdeveloped, academic content areas on Wikipedia.
  • AMD HSA IL / BRIG Front-End Still Hoping To Get Into GCC 7
    For many months now there's been work on an AMD HSA IL front-end for GCC with supporting the BRIG binary form of the Heterogeneous System Architecture Intermediate Language (HSA IL). It's getting late into GCC 7 development and onwards to its final development stage while this new front-end has yet to be merged. Developer Pekka Jääskeläinen has been trying to get in the finishing reviews and changes for getting approval to land this BRIG front-end into the GNU Compiler Collection. It's a big addition and with GCC 7 soon just focusing on wrong-code fixes, bug fixes, and documentation fixes starting on 19 January, there would be just a few days left to land this new front-end for GCC 7 to avoid having to wait until next year for it to debut in stable with GCC 8.
  • Rcpp 0.12.9: Next round
    Yesterday afternoon, the nineth update in the 0.12.* series of Rcpp made it to the CRAN network for GNU R. Windows binaries have by now been generated; and the package was updated in Debian too. This 0.12.9 release follows the 0.12.0 release from late July, the 0.12.1 release in September, the 0.12.2 release in November, the 0.12.3 release in January, the 0.12.4 release in March, the 0.12.5 release in May, the 0.12.6 release in July, the 0.12.7 release in September, and the 0.12.8 release in November --- making it the thirteenth release at the steady bi-montly release frequency. Rcpp has become the most popular way of enhancing GNU R with C or C++ code. As of today, 906 packages on CRAN depend on Rcpp for making analytical code go faster and further. That is up by sixthythree packages over the two months since the last release -- or about a package a day!
