Fedora @ Konteh 2017 - event report

DSC_0045.JPG

This year we managed to get a booth on a very popular student job fair called Konteh. (Thanks to Boban Poznanovic, one of the event managers)

Konteh is an annual event where local companies send their recruiters to find young, educated students who would be good candidates for open positions at their companies. As it is primarily a job fair, at first I wasn’t sure if this is a place where Fedora would benefit from a booth, but the number of people asking about what is it, what do we do and how to join certainly changed my mind.

DSC_0046.JPG

This year Konteh took place on Wednesday 23 and Thursday 24 March at the Faculty of Technical Sciences in Novi Sad, Serbia.

Our booth was on the second floor of the main venue. I had some leftover Fedora goodies (DVD’s were a hit!) from previous release parties, so this was a good opportunity to share it with a great number of CS students.

Fedora on BayTrail tablets (2017 edition)

Almost two years after writing my post about running Fedora on a BayTrail tablet, I decided to provide a small update.

Even though a lot of support landed in kernels 4.8 and 4.9 there are still a few things needed fixing. The good news is that out-of-the-box experience is much, much better now, with almost everything working.

So let’s get to it!

 Fedora version, and deskop environment

I recommend starting with a i686 Fedora Workstation image. If GNOME is slow on your tablet you can later install another DE (I installed XFCE).

Remember that you will most certainly need GDM because it is the only Login Manager which supports touch screens.

 Getting it to boot

When you download the i686 ISO, you will need to extract it to a blank FAT32 formatted USB drive. You will still need the bootia32 trick to get GRUB loaded.

 Fixing black screen on boot

One of the biggest issues with BayTrail

Fedora 25 Release Party Novi Sad

20161211_135630.jpg

Another awesome Fedora release, and another awesome Fedora Release Party in Novi Sad! :)

This is my short event report from the Fedora 25 Release Party in Novi Sad.

This time the organization went really really smooth (we were infinitely more experienced than the last time - it was our first event), and I met a lot of new Fedora people and had a chance to talk about Fedora with everyone!

The party took place, like last time, on the Faculty of Science, University of Novi Sad in the biggest amphitheater of the Department of Mathematics and Informatics. To be even more precise it’s about 3 minutes away from our Fedora-powered computer lab!

About 40 people (among who was a Fedora ambassador from Uruguay!) attended and we had four talks about different topics, regarding Fedora, Security and Hackerspaces.

Anyfed (Universal Fedora chroot tool) - First release

A small update. I wrote a small shell script which can set up a Fedora chroot anywhere (get the name now?) where a compatible kernel is. This means you can use minimal Fedora shell on almost any other Linux distribution.

Here is the project homepage and source code:

https://github.com/nmilosev/anyfed

You use it like this:

wget https://raw.githubusercontent.com/nmilosev/anyfed/master/anyfed && bash anyfed

The only prerequisites are that you have tar and wget in your $PATH, you don’t even have to be superuser. It should work on any recent ARM or x86_64 kernel. I’ve tested it on my Android phone, my Raspberry Pi (with LibreELEC) and a couple of virtual machines and it is working really good.

The use cases are very broad. For example for running software which isn’t available on your installed distribution, or to try out dnf and other Fedora-specific tools. Also, this could be very

Termux-Fedora - install Fedora on your phone with Termux

Termux is an awesome new open source app for Android which provides you with a basic Linux shell. It also has a tiny repository with some packages and one of those packages is proot which you may remember from my GNURoot tutorial.

GNURoot way of getting Fedora on your unrooted Android phone still works, but this way is much cleaner and we have more control over what’s going on. I’ve been using this for a couple of days and it has been really stable and fast.

Anyway to install Fedora on your unrooted (or rooted) Android phone you have to:

  • install Termux from the Play Store or the F-Droid store
  • open it and paste this little snippet:
apt update && apt install wget -y && /data/data/com.termux/files/usr/bin/wget https://raw.githubusercontent.com/nmilosev/termux-fedora/master/termux-fedora.sh && sh termux-fedora.sh

and wait. If everything goes well, you can enter Fedora chroot with a

Quick and easy Fedora Minimal chroot

This is a quick guide on how to quickly make a Fedora Minimal chroot environment without any special tools. The only prerequisite is that you have root access on the machine you are using, and chroot binary (or busybox even). I am also using wget and tar but you probably have that. :)

We are going to use a Docker image as it contains a very well packaged Fedora Minimal rootfs.

Docker images are available for x86_64 and ARM architectures here:

https://download.fedoraproject.org/pub/fedora/linux/releases/24/Docker/

I am setting up my Raspberry Pi 2 in this example so I used the ARM image. The “host” operating system is LibreELEC media center, but this will work on any Linux distribution.

# make sure you are root
sudo su

# create a directory for Fedora
mkdir -p /fedora 
cd /fedora

# get the Docker image
wget

Sadly I have to start with sadly. The package with Fedora goodies was again impounded by the Serbian customs, and this time we couldn’t do anything about it. I was really sad and annoyed, but I guess this is just a

Fedora 24 + Bumblebee + CUDA + Theano

It’s very frustrating when you want to try something out quickly and lose your entire day… But at least next time it will be easier. I hope.

This is a guide on how to run Keras (Theano powered neural network Python library) on CUDA with an NVIDIA Optimus laptop, with Fedora 24 and Bumblebee.

 Bumblebee working

Get Bumblebee working, that is the easy part. Use the nonfree drivers, there are very good instructions here:

https://fedoraproject.org/wiki/Bumblebee

Afterwards verify that Bumblebee is working with a quick:

optirun glxgears

 Install CUDA

Get CUDA from here:

https://developer.nvidia.com/cuda-downloads

The version for Fedora 21 is the latest one, and it will work. Unpack it after downloading it with:

sh cuda_7.5.18_linux.run -extract=/path/to/somewhere

You will get three files, the driver (which you don’t need), CUDA toolkit and some samples. Install the toolkit and

Fedora @ EuroPython 2016 - event report

DSC_1342.JPG

I am just sitting here, unsure how to start to describe probably the best conference I have ever attended! I was given the privilege to attend the biggest Python conference in Europe, meet the Python community, see what is new in Python world, and the best part was that I was representing Fedora Project.

Five days, hundreds of smiling faces asking about Fedora and Red Hat, great food, the ocean, the beautiful city, everything was there!

Here follows my personal event report, and I will try to keep it short, but no promises! :)

Fedora (represented by Michal from Red Hat Brno and myself) was sharing booth with Red Hat, which was great because when someone is interested in Fedora, you can also talk to them about Red Hat and vice versa.

Jiri and Marta, recruiters from Red Hat Brno were amazing. You can clearly see that they are really good at this sort of stuff. They

Fedora 24 Release Party Novi Sad

e29ye4V.jpg

I just finished organizing my first event for Fedora - Fedora 24 Release Party in Novi Sad!

We had three great talks, a Fedora quiz, around 60 very happy people and a lot more. :)

The pictures from the event are here: http://imgur.com/a/5TE3O

The presentations and the quiz (for the curious) are here: https://nmilosev.fedorapeople.org/f24rpns/

Big thanks once again to Department of Mathematics and Informatics of the Faculty of Sciences in Novi Sad for having us. Also big thanks to Kveta and Romana from Red Hat for getting us t-shirts, stickers and a lot more in time, even though Serbian customs were tough. Lastly, huge thanks to everyone who helped with the organization, and to Doni Pracner and Momcilo Medic (FedoraUser) for the great presentations.

When I catch some time (and my breath) I will write a more detailed report, so stay tuned! :)

First of all sorry for not
