From June 27 to July 1 there was a Hack Week at the SUSE headquarters in Nuremberg, although I could only stayed the two first days. I hacked on OSEM together with Stella, Henne, Chris and Moises and I really enjoyed it. And SUSE office is really cool, there were chameleons and penguins everywhere, even in plants and mugs!

And to be consistent with my other posts I’ll also show you what I ate at the Hack Week. That is the breakfast we had the second day, it was really strange for me having sausages for breakfast and even more if they are white and green haha.

And sadly that’s all about my travel to Germany as then Geeko and I came back home.  It was a really wonderful experience.

Fourth day of the conference

On Saturday I went to the openSUSE Wiki Workshop. We were talking about the problems that the Wiki has and how to solve them. After that, I was going to contribute to the Wiki, but it was broken.  

Then, I had pizza for lunch, there were a lot of pizzas:

I didn’t attend any other conference that day, but I stayed at the conference place working on OSEM.

In the evening we went to the Octopus party organised by the Galician centre of Nuremberg, where I ate Paella. It was strange eating Paella in Germany, although it was better than some Paellas I have eaten in Spain.    And again, I was surprised by the amount of Spaniards that are living in Nuremberg. Although it has been really sunny all day, just when we finished eating it started raining cats and dogs.

And at night we went to dance. I was really impressed by Matheus, he dances incredibly well.  

Last day of the conference

On Sunday I went to the openSUSE: much more than Linux distributions talk, by Ancor González Sosa. He talked about the open source projects living under the openSUSE umbrella such as OSEM, Portus, Jangouts, Machinery or zypper-docker. He also mentioned openSUSE 101, openSUSE mentoring program, and the openSUSE GSoC projects as they are related with those project under the openSUSE umbrella. Then, it was the openSUSE Targeting the Education Sector talk, by Douglas DeMaio. I really liked the following sentence that Douglas said:

You can’t imagine how hard it is to sell something which is for free

Lastly, it was the openSUSE Project Meeting, where people could share their ideas or propose changes. Regarding the conference, most people liked the place where the conference took place but they would prefer the conference to be shorter (3 days instead of 5)  and to have free water as there were some free drinks but no water. Also, there were complains about the marketing support for openSUSE less known projects. I agree, I want an OSEM‘s opossum sticker!

As on Sunday the conference ended before to allow people to return home there were not more talks that day. We had lunch and I talked with the people that stayed longer. And I also got a Geeko biscuit cutter printed with a 3D printer, I’ll put picture in the blog when I make Geeko biscuits! Here you have a pictures of the biscuits cutter finished and also a video of how it was printed:

In the evening we went give a walk around Nuremberg:

And of course we took the little Geeko that we were given at the conference with us:

We went to a street where there were columns with the humans rights on them. Every columns has a right in German and in other language. It was funny because the Spanish one was a circle in the floor instead of a column haha.

At night we had something delicious for dinner: Currywurst.    It was the only dish in Germany that I ate completely  haha.

And after that I got my two first books in German, one is a tale, so I hope to be able to read it soon, and the other one is a recipes book. I’ll probably use the recipes one earlier  

Lastly, I took the last picture with Matheus as he was leaving on Monday morning and that was the last time I saw him  

And that was all about the openSUSE conference 2016. I was really happy to meet my mentors and to put faces to nicknames as I met a lot people who I usually see in Github. I learnt many things, met a lot of people and had really fun. I hope to be able to go to next openSUSE conference and to met everyone there again!  

I stayed two more days for the Hackweek and I’ll write about that in the next post.  

At work we are using GitLab Comunity Edition hosted on our servers. GitLab includes Git repository management, code reviews, issue tracking, wikis, plus GitLab CI, a continuous integration and deployment tool similar to Jenkins or TeamCity.

Being responsible with architecting and implementing the infrastructure for our web application, I spent the last days implementing the continuous integration/deployment pipeline. Here is just a short tutorial about how to install GitLab Runner, an application which processes builds. It can be deployed separately and works with GitLab CI through an API. In order to run tests, you need at least one GitLab instance and one GitLab Runner. The installation is done on SUSE Linux Enterprise Server 12 but should work on openSUSE, as well.

Even if on their website, SUSE is not mentioned, the binary, writen in GO, is working perfectly fine.

• download the binary and save it in /usr/local/bin/

# wget -O /usr/local/bin/gitlab-ci-multi-runner https://gitlab-ci-multi-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-ci-multi-runner-linux-amd64

• let's make it executable

# chmod +x /usr/local/bin/gitlab-ci-multi-runner

• check to see if is working

# gitlab-ci-multi-runner --version
Version:      1.3.2
Git revision: 0323456
Git branch:   stable-1-3
GO version:   go1.6.2
Built:        Tue, 28 Jun 2016 14:03:09 +0000
OS/Arch:      linux/amd64

• create a GitLab CI user which will be responsible for our automatic builds and automatic deployments

# useradd -m deploy
# passwd deploy
New password: ...

• now we have to register the Runner. But before to do that we need a specific token and a "coordinator" URL which is generated by GitLab. In order to get them go to: Your GitLab Project -> Settings -> Runners, see the screenshot below.

# gitlab-ci-multi-runner register
Running in system-mode.

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/ci):
https://your-server-where-gitlab-is-installed/ci
Please enter the gitlab-ci token for this runner:
[your-unique-token]
Please enter the gitlab-ci description for this runner:
[our-little-gitlab-runner]:
Please enter the gitlab-ci tags for this runner (comma separated):
Registering runner... succeeded                     runner=fD_qnhkt
Please enter the executor: docker+machine, docker-ssh+machine, docker, docker-ssh, parallels, shell, ssh, virtualbox:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

• run the runner as a service

# gitlab-ci-multi-runner install --user=deploy --working-directory=/home/deploy/gitlab-runner

• start the service

# gitlab-ci-multi-runner start

• check if the runner is running

# ps aux | grep gitlab
root     25687  1.5  0.1  64192 14584 ?        Ssl  20:10   0:00 /usr/local/bin/gitlab-ci-multi-runner run --working-directory /home/deploy/gitlab-runner --config /etc/gitlab-runner/config.toml --service gitlab-runner --syslog --user deploy

• check if build started (after a few seconds)

# ls -ltr /home/deploy/gitlab-runner/builds/
total 4
drwxr-xr-x 3 deploy users 4096 Jul  6 20:10 baf1e27f

I didn't mentioned until now but you also need a .gitlab-ci.yml in your repository. Check the available documentation.

tI am going to start showing you some of the pictures with Geeko that we took during the day  

Apart from taking pictures with Geeko, in the morning we had a GSoC meeting with all the students and mentors that were at the conference. In the meeting we talked about the importance of blogging, what students and mentors use to talk or have meetings, how every team review pull requests, why students chose openSUSE for GSoC, etc.

After having lunch I attended the How to bring SUSE/Linux to school! talk, by Emiel Brok. He gave 11 tips to bring Linux to school which you can see in his slides:  OpenSUSEconf2016. When the talk finished, I went to the Getting started with Docker workshop, but it had almost finished.

And then it was time to enjoy openSUSE swimming pool and to eat some barbecue:

Yes, it is a very small swimming pool, but it was reeeeally hot that day, so it didn’t matter.  

It was also taken the group picture:

Lastly, we went to see/listen SUSE Band:

It was a really fun day! I’ll write one more post about the last two days of the conference.  

We have come a long way since the first Li-f-e live media based on openSUSE was created, the current release is based on openSUSE Leap 42.1. Deployments by Indonesia’s education system is a shining example of openSUSE Education project’s accomplishment.

The openSUSE project has stopped producing live medias for Leap and also live-installer is dropped from live medias created for the Tumbleweed distribution. As Li-f-e is primarily a live distribution we would not be able to create any more medias without live-installer. So unless this situation changes we may not have Li-f-e based on Leap 42.2.

In the meantime I’ve had a look at Ubuntu to create Li-f-e based on the latest LTS release of Ubuntu-Mate, check it out here. Software selection available is kept identical to the Li-f-e based on openSUSE, however there is always a room for improvement, suggestions to enhance it are always welcome.

As part of my work on rootless containers, I found that many tools try to drop privileges. This makes those tools break inside rootless containers, so I spent a week or two working on a tool that allows users to shim out all of the "drop privileges" syscalls. Here is documented the pain that I went through while figuring out how ptrace(2) is meant to work.

The second day was for me the one with best talks and workshops. First, I attended the keynote from Frank Karlitschek, founder of Nextcloud. After that, I went to Ancor González Sosa workshop, openSUSE wants you: the software portal. I downloaded the software-o-o project and started seeing how it works. At lunch time I had some strange food.

Then, I attended the Teaching opensource talk, by Craig Gardner. It was mainly focused on how to turn students into contributors, but Craig also talked about the benefits to schools, the fact that most big companies loves open source and why it is important to teach open source. I really recommend you to see the slides he used, specially if you do not agree that teaching open source in schools and universities is that important, as I think the slides will make that you change your opinion.You can find them here: Teaching open source 2016.

After that, it was Henne Vogelsang talk about openSUSE 101, the openSUSE mentoring program which has been used in GSoC. I found the slides and the presentation really fun. I would like you to see it but unfortunately there is no video of the talk. Although you can see the video that he played when talking about the fact that variety is needed in open source. I had seen it before Henne talk but it was still funny:

Lastly, I went to the end of the Ruby on Rails 101 workshop and to the 20.000 Leagues Under SUSE Studio workshop, both of them by Christian Bruckmayer. I liked a lot the slides of the second workshop which you can find here: 20.000 Leagues Under SUSE Studio

Cellar tour

In the evening I went to the cellar tour, which lasted around 75 minutes (the same of the city tour more or less) and where I also learnt a lot of things. It is astonishing that Beer used to be healthier than water in Nuremberg hahaha.

After the cellar tour we went to eat Schnitzel, a huge steak with a strange cover. As you should have already noticed in my previous post all dishes are tooo big in Germany. But not only dishes, drinks and even ketchup packets are too big. The German ketchup packet has 20ml, while in Spain it usually has only 10g. That means that you have to open around 4 ketchup packet in Spain to get the amount of ketchup that you get in Germany in only one packet.  

And that is most of what I did the second day of the conference. I have a lot of nice pictures with Geeko of the third day which I will include in the next post.  

After taking two planes I arrived to Nuremberg on Tuesday 21 to attend openSUSE Conference 2016, which took place from June 22 to June 26.

Pre-conference party

That night it was the pre-conference party, where I had the chance to try openSUSE beer and to meet a lot of people. I met some openSUSE workers from Canarias, such as Moises, entertainment manager Senior Rails Web Developer at SUSE, the GSoC students Joaquín and Rishabh, my mentor Chris and some others that I won’t mention to avoid doing the post too long.

First day of the conference – Wednesday 22

In the morning I helped in the registration desk. After that I attended the last part of the SaltStack is more than just configuration management talk, by Thomas Hatch, and the Introduction to the Linux Block I/O Layer and Hawk 2.0 and Beyond talks, by Johannes Thumshin and Kristoffer Grönlund respectively. I found interesting the Hawk talk. You can see the video of these talks and some other in the openSUSE youtube channel. I also met Matheus, the last GSoC student that was coming to the conference.

After that, I had a pulled pork bbq sandwich for lunch taken from Ribwich Food Truck. Ñaam.

In the afternoon, I attended the The type C connector and USB 3.1 talk, by Oliver Neukum, while being in charge of giving the people who wanted to ask questions the microphone. It is funny because I appear in the last part of video of this talk hahaha.

Lastly, I went to the How to Contribute to an Open Source Project workshop, by Lasse Schuirmann. I found the workshop really useful: I learnt some things about Python data structures and git that I didn’t know, I learnt what Coala is and I made my first contribution to the coala-bears project. What Lasse told us about Coala in the workshop was similar to what he said in his Static Code Analysis for All Languages – coala! talk. I couldn’t go to that talk, but I’ve seen the video and I recommend you to see it. I think that Lasse is a really good speaker and the talk lasts only 15 minutes. You can find it here: Lasse Schuirmann: Static Code Analysis for All Languages – coala!

City tour

On Wednesday 22 evening I also went to the city tour organized for the conference. The tour lasted around 75 minutes and I learnt many things. I had already seen pictures of Nuremberg in Google, but I was really impressed by how beautiful the city is! Here there are some of the picture I took:

And my favourite one, which I prefer to include separately:

After that, we went to have dinner to a Thai restaurant where I ate a delicious duck and to the Nuremberg “beach”.

That’s all from now, I’ll continue writing about the conference in the next post.
