KDE Project Br-Print3D at Campus Party Brazil

Last week, between January 26 and 31, the ninth Campus Party Brazil (promo video on Facebook) was held in Sao Paulo. 8000 people inside an arena, with talks, workshops and hackathons, with the main subject being technology.

The team from KDE project Br-Print3D was invited to participate of this event. To show our work on the Free Software stage and on the tables there are scattered all over of this arena.

Br-Print3D written in Qt

We received sponsorship from Sethi3D, a Brazilian company that makes 3D printers here. They kindly gave us four 3D printers to use, 3 of them with a 20cm3 print area and one with 40cm3. We made a lot of prints, that you can see on our album on Facebook.

Sethi BB – 40cm3 area of printing

Over the five days almost 500 people stopped on our table to talk about 3D printing and to learn about our project.

At the event we are had more access to different printers and we saw how other firmware variations work. Focusing on Repetier we were for the first time able to test formally Sethi’s printers and we detected some particularities of this firmware which probably can be found on others models.

They were five days of challenges, compliments and reviews about our work. I made a talk about C++ and Qt, and how to use Qt to develop user interfaces. What is funny, that only 7 people attending my my talk, out of over 100, knew about Qt and only one really worked with it. That was the same feeling that I had when I started work with Qt. It’s hard do find people that knows Qt here in Brazil, mainly if you don’t have more information or connection to open sources projects.

Why robots can’t live without apps


We’re living in a pretty exciting period where robots have become ever more present in our “human lives”. They aren’t simply watched in Sci-Fi films on our living room screens anymore, but like the BB8 they are rolling around our homes (!) transforming our videos into holograms.

As the world we live in gets smarter, we all expect new devices that will change our lives….and smart robots are first in line to deliver these differences! They can transform the way we work to be more productive, assist in our personal life with household chores and even help the ageing population through greater independence.

The potential of smart robotics is huge! Though to get there they have to be up-to-date with what is and isn’t working in our society and understand what we are using in our daily lives so they can bring about these transformations.

They need a smart ecosystem. One that’s relevant, up-to-date with user experiences…something like an app store.

Robots powered by apps hold a longer life span as they rely on software updates which maintain their relevance. Think about a robot that’s controlled via a social network. If this network loses popularity after a few years and a new one takes the crown – not an unlikely situation – a robot connected to an app store can get a software upgrade or a new app downloaded which will give it a new life. Robots without apps just do not have a future with consumers always demanding a more relevant, more affordable option.

Robot App stores probably hold the most important roles in the future of robotics, as this is where the industry’s greatest potential lies. It’s still far away from the popularity of phone apps but as the robotics industry grows and more developers participate, be it professionals, students or hobbyists, this will inevitably change.

We’re excited to be a part of this change and can’t wait to showcase some of these app powered robots at Mobile World Congress (MWC) this year.

Erle Spider, is an Ubuntu drone with legs! It’s powered by ROS, the programming language for Robots, and has a couple apps that make him a very special robot indeed. The spider can be remotely controlled via a Twitter app and whatever the robot sees can also be streamed on YouTube via its app!

The same makers, Erle, launched its first flying drone with apps at the back of a successful crowdfunding campaign in 2015 which we’ll also be showcasing. Drones are the fastest growing market in the robotics space, particularly led by commercial drone adoption. The Erle Drone powered by Ubuntu Core can easily be extended through a number of apps including the Youtube streaming app and the Altitude Angel app that prevents drones from going into no-fly zones.

And there’s UAVIA, which is the only drone in the world to be entirely remotely piloted via a 4G connection. This is an interim step between a fully autonomous and locally piloted drone which means venues could have a drone in residence which would land in a nest to get recharged after each flight.

Drones and Robotics are an exploding market! And for those of you heading to MWC we’d love to discuss this topic more. For more info on our MWC demos see here.

Google removes Samsung’s first Android ad blocker from the Play Store

Just days after it shot to the top of the Play Store, Android’s newest ad blocker has been removed for violating developer guidelines. Called Adblock Fast, the plug-in from startup Rocketship Apps worked within Samsung’s mobile browser thanks to a partnership with the phone maker, which opened an API this week allowing third-party developers to build content blocking features for the preinstalled Samsung Internet app.
According to Rocketship developer Brian Kennish, Google says Adblock Fast violates section 4.4 of of its Developer Distribution Agreement, which disallows apps or plugins offered through the Play Store from “interfering” or “disrupting” devices, networks, or services of third parties.

Justin W. Flory: How do you Fedora?

We recently interviewed Justin W. Flory on how he uses Fedora. This is part of a series on the Fedora Magazine where we profile Fedora users and how they use Fedora to get things done. If you are interested in being interviewed for a further installment of this series, you can contact us on the feedback form.

Who is Justin W. Flory?

HDYF - Desktop

Justin W. Flory is a student majoring in systems administration and networking at the Rochester Institute of Technology (RIT). His minor is in Free and Open Source Software. He has professional training as a barista and supports direct trade coffee. “I am also a coffee fanatic,” Flory said. “I can make some pretty fantastic espresso with the right equipment.” Justin has been fascinated with computers since a young age. He credits Minecraft with changing his life. “Minecraft is a game that has changed my life, beginning with my own early experience with entrepreneurship and later my experience with the Spigot community, which landed me the opportunity to go to London this past July to attend the annual Minecraft convention, MINECON. It also indirectly introduced me to Linux and Fedora.”

Flory is not a big fan of movies and he doesn’t watch TV, but his favorite two movies are Inception and The Matrix. Justin’s favorite food is smoked salmon with cream cheese on crackers.

The Fedora Community

Justin wanted to become an Ambassador for most of 2014, but did not take the leap until after attending Flock 2015. At Flock 2015, Flory was pulled in by the tight-knit nature of the Fedora community. “I could see that the friendships made from Fedora went beyond IRC, lines of code, and more into real life.”

When asked about one thing he would like people to know about the Fedora Project, Flory said, “You don’t have to be a code whiz to be a Fedoran. There are so many different places you can help.” Justin is also inspired by being part of a community that is passionate and dedicated to making a positive impact on the world.

The person most responsible for helping Flory become involved is Remy DeCausemaker. “I have to thank Remy DeCausemaker for opening the Fedora door for me,” Justin said. DeCausemaker gave him advice with regards to attending Flock 2015 and has helped Flory become more involved in the Fedora Community. He also wanted to thank Paul Frields, Ryan Lerch, Gabriele Trombini, Bee Padalkar, Patrick Uiterwijk, and many more.

Justin contributes mostly through Fedora Community Operations (CommOps) and Fedora Marketing. He finds CommOps exciting because he gets a bird’s eye view of the entire Fedora Project. Flory stated, “I’m still learning the ropes, but I feel like I’m able to see the big map of Fedora, observe where everyone else is, and help figure out how to make sure everyone can land and take off safely.”

When asked about the advice he would give people who are thinking about becoming involved in the Fedora Project, Flory was very emphatic. “Do it! Don’t wait!” He recommends joining #fedora-join on Freenode and asking for some help finding a place to contribute.

What hardware?

Flory has several pieces of hardware. He has a self-built desktop he made in 2014, a laptop, and another self-built server made in 2015. His desktop has an AMD FX-6300 processor coupled with 8GB of RAM and an Nvidia GeForce GTX 660 Ti graphics card. The boot drive is an SSD, but he pairs that with a traditional 1TB hard drive. The FOSS Fighter, as he calls it, is currently running Fedora 23 Workstation.

Justin’s laptop is a Toshiba C55-A equipped with an Intel Core i3 processor and 4GB of RAM. It is currently running Fedora 23 Workstation, but he is considering getting an upgrade or running Xfce due to the age of the laptop.

Justin W. Flory, how do you Fedora? The FOSS Fighter

Inside the FOSS Fighter

The server is another home-built system and is equipped with an Intel Core i7-4790S and 24GB of RAM. RIT provides a free RHEL license, so Flory runs RHEL 7 on the server. It currently hosts RITcraft, RIT’s official Minecraft server.

What software?

HDYF - Rhythmbox

As a music lover, Flory depends on Rhythmbox for playing his library and Scrobbling his plays to Last.fm and Libre.fm. He also makes use of MusicBrainz’s Picard to categorize, sort, and correct metadata for all of his music.

For messaging, he makes use of both IRC and Telegram. For IRC, Flory is a fan of HexChat and is active on Freenode, SpigotMC, and Espernet as jflory7. For personal messaging, Justin uses Telegram on his laptop using the desktop app or on his Android when he is without his laptop.

As a student, he depends on LibreOffice for his productivity suite. Writer helps him take notes in class, creating PDFs, and other tasks. He makes use of Dropbox to keep his files synchronized on all of his devices.

Juju Charmer Summit Update

Author Tom Barber is the Technical Director of Canonical Charm Partner Meteorite Consulting.  He is currently attending the Juju Charmer’s Summit in Ghent, Belgium.  

Juju Management Camp Day 1

Okay it’s a lie, it was really Config Management Camp, but I was really only there for one purpose. Over the years as a small tech company we have tried a number of automation systems for our server and the honest truth, is that unless you have a dedicated sys admin and people running your infrastructure, it will fail at some point. The urge to do something “manually” is too big a draw and as soon as you do that, your systems are out of sync and it’s hard to come back from that point. Of course with Juju you can do that also, but as the systems are designed at a different level, it removes that “hackable” level and manages my servers and containers for me, which to some extent minimises that urge.

The other thing as well is that all “recommended charms” (the stuff you deploy with Juju) are peer reviewed by Canonical employees, and, as I found out tonight, are automatically tested on a range of cloud services with each commit. One of the bigger problems we found with Puppet over the years was finding Puppet modules that were built in a way that allowed easy deployment on my operating system of choice without hacking to move it out sync with the upstream maintainer. Of course you can still do this with Juju, but the charm developers add sensible properties into their charms in the hope this won’t be necessary. You can also extend charms with their new “layers” approach coming in 2.0, if you come from a programming background, think of inheritance, you can extended charms with more code, without writing all the other stuff or copying and pasting.

The other take away from today, is how enthusiastic all the folks at Canonical are about their product. This is from the top down, from Mark Shuttleworth, wanting to do seat of the pants demos with the Ubuntu Orange Box (http://cluster.engineering/ubuntu-orange-box/) and answering questions in detail on the mailing list. To Jorge and his love of ZFS, Antonio and his wanting to demo the Juju Weather Report to me so I understand how the cross cloud testing metrics work and of course Marco Ceppi who thinks (quite rightly) that every question is a really good question and answers it in as detailed way as possible, how he didn’t lose his voice is beyond me.

The whole setup is really slick, whilst most techies may not use the GUI, it is there and readily available for systems engineers to explain platform topology to no techies, but similarly, the command line and its excellent tab complete support is there to support day to day tasks. The ease of adoption and getting up and running is so easy, it makes you want to use the platform for everything, instead of it being an after thought.

I have to be honest with you, when we were asked to write a Saiku charm, I was sceptical, YACMS (yet another content management service), but the whole ecosystem has changed from, “let’s write a charm and hope people consume it”, to, “lets port our systems to Juju because it makes our lives easy and if people use our charm thats a bonus”.

Of course Canonical would like us to get our charm finished and everything in production but from a consumers point of view, Juju is good. Very, very good.

Flock 2016: Kraków, Poland

The Fedora Project is pleased to announce the 2016 Flock conference, coming August 2-5, 2016 in Krakow, Poland. At Flock, Fedora contributors gather to promote and discuss ideas to improve our distro, community, and userbase, and promote our core values: Freedom, Friends, Features, First.

Past and future Flock locations

The first Flock conference was held in Charleston, South Carolina in 2013. The event has alternated each year between North America and Europe. The 2014 conference was held in Prague, Czech Republic. In 2015, it returned to the US in Rochester, NY, and this year visits Krakow for its European location.

Want to know more about the process and effort that went into finding the venue this year? Check out this post from the Fedora Community Blog. (This is also a great way to learn how to win a bid for next year.)

What Flock is like

Flock operates somewhat like a traditional conference. We have a call for papers (CFP) in which participants submit talks for acceptance. This differs from our previous, Barcamp-style FUDCon events. This arrangement has worked exceptionally well for the past three years. This year promises to be one of the best Fedora conferences yet.

The Flock 2016 conference will feature four full days of talks, workshops, hackfests, and sprints. Your submission is encouraged, since we want to fill the schedule with good content. And of course there will be opportunities to interact with other contributors throughout the conference.

We’ll have scheduled sessions covering these and other topics:

  • Building a Better Distro
  • Growing the Fedora Userbase
  • Making Life Better for Contributors
  • Prepared Lightning Talks (plenary session)
  • Team Planning
  • Hackfests
  • Drop-in Clinics
  • Open hardware
  • …and more

Register and submit talks now!

Information is coming soon about CFP deadlines, hotel lodging, and more. But you don’t have to wait! You can submit your talks along with your registration right away. Visit the official website for Flock 2016 now, where you can register and submit a talk.
