Consequences of the HACK CAMP 2016 FEDORA + GNOME

I used to do install parties in order to promote the use of FEDORA and GNOME project since five years ago. As you can see more details in the Release Party FEDORA 17 for Fedora, and Linux Camp 2012, GNOME PERU 2013, GNOME PERU 2014:

peru01To the fifth edition of GNOME PERU 2015 I asked FEDORA to be a sponsor and they kindly accepted, it was included in a video and some pictures of the support as follow:

peru02Fedora and GNOME work different, we have in Perú many ambassador of FEDORA and only three members of the GNOME Foundation. That is why I have seen more FEDORA events than GNOME, and I was trying to reach more users of GNOME on FEDORA.

Anytime I have to do a local or international workshop or a class in universities, I do spread the FEDORA + GNOME word. Some pictures of the DVDs I have given for free:

peru05As well I have seen many students that now are working with Linux-related technology, but there was not a real contributor, neither for FEDORA or GNOME community that I brought to these project. I have also been involved in many Linux groups in Lima too, with no success in bringing new real contributor. These efforts were not enough…

peru07This year, 2016, I decided to focus directly to developers and instead of having long quantity of audience, I chose to keep the eye on quality.

I found a group in Lima called Hack Space where they train people to code, and this summer they gathered students from many parts of Peru. These students were not just students at universities, they were extraordinary students at self-training and also “leaders” in their communities. I decided to take them to a Hack Camp and it was a coincidence that HackSpace were also planing this activity! So we joined to use code on Linux though FEDORA and GNOME. This was possible thanks to Alvaro Concha and Martin Vuelta, and of course the sponsor of the GNOME Foundation. We did have 5 days:

peru08After the HACK CAMP 2016, I was be able to be part of the conference CONEISC 2016 because a participant of the HACK CAMP 2016 was part of the organization in his local community. I traveled to Pucallpa (jungle of Peru) in order to spread the FEDORA+ GNOME word (this time I was not sponsored neither by GNOME or FEDORA).

peru09Because CONEISC 2016 congregated business and professionals related to computer and science. There was an opportunity to interact to other formal entrepreneurs interested in promoting Linux technologies such as DevAcademy and Backtrack Academy.

I am arranging special editions related to FEDORA and GNOME. Both channels have achieved more than 2,762 views. DevAcademy has 6,750 subscribers and BacktracAcademy had reached  5,393.

  • Another talk I have gotten because some participants at CONEISC 2016 enjoyed my workshop, is going to be presented at the SEISCO event that will be held at UPN:

14714804_188926978215598_7074006320136480389_oAnd finally, the most important part of all these effort for more than five years is Martin Vuelta, who supported the organization of HACK CAMP 2016! He is a potential contributor to FEDORA and then, because we both attended the FUDcon LATAM 2016 event, we saw also an opportunity to build the GNOME PUNO initiative!😀

There are lots of plans to grow in my local community! Thanks FEDORA and GNOME!❤

Attending a FUDcon LATAM 2016

From my experience I will share my days at FUDcon 2016 held on Puno last week. There were 3 core days, and 2 more days to visit around.

Day 0: 

Martin & I departed from Lima to Puno around noon to find FEDORA guys as Chino, Athos, Wolnei and Brian. After walking around to reach our hotel, we found FEDORA posters on streets. Then we shared a traditional food called “Cheese Fries” and went together to the “hair comb mission” during the afternoon. Got altitude sickness at night😦

fedora1Day 1:

FEDORA contributors were presented in the auditorium and then the BarCam took place. I have helped to count the votes in “Dennis Spanish”. We shared food at fancy restaurant for lunch. Then, I attended three talk according to my interests: Kiara’s talk since I do research with IoT, David’s talk because I am a professor at university and Chino Soliard’s talk about SElinux.  At night we shared a delicious “pizza de la casa” served by “Sylvia” 😀

fedora2Day 2:

During the morning I have tried to cheer up audience by pricing with FEDORA stickers, pens and pins during the gaps of the presentations of Eduardo Mayorga (Fedora Documentation Project), Jose Reyes (How to start with FEDORA) and Martin Vuelta (Python, Arduino y FEDORA). To lunch I chose “Trucha Frita” and during the afternoon I presented “Building GNOME with JHBUILD”. I introduced people into the GNOME project and encourage people to install FEDORA 25. For dinner we shared “Chaufa” and bills from many countries. Thanks to Mayorga for guiding my steps to the FEDORA planet

fedora3Day 3:

This was a pretty long day…

It started by helping in translating Brian’s talk as well it was done by Mayorga and Kiara, people was interested in clarify the differences among FEDORA, CentOS, FEDORA and UBUNTU. Brian mentioned us the ATOMIC project and explaining kindly the current status of FEDORA. (We are growing! at least in one percent🙂

fedora4During the lunch, local people get in touch with me to start the GNOME PUNO project, I found enthusiastic young people that I did not imagine to find! I decided to give some minutes during my second talk DNF(Dandified YUM) to present the GNOME customization in the login part. After my talk the GNOME PUNO effort got two more members! We decided to prove our attempts by registering our tasks in our blogs!😀

fedora5For the closing event we received some presents from the organizers and we shared our passion to the FEDORA project to locals. We celebrated also with typical dance of Puno.

fedora6For dinner we shared “Pollo a la brasa” and then I helped in the preparation of the barbacue for the next day!… the following pictures belong to Tonet and Abhadd:

fedora7Day 4:

This was another long day, but a touristic one. We started by visiting Sillustani (pre-Inca cementery on the shores of Lake Umayo). Then we shared the barbacue with the group for lunch. At the afternoon we went to the Chucuito Fertility Temple (famous for phalluses). Special thanks to Gonzalo from FEDORA Chile who kindly agrees in sharing his photo:

fedora9At night we visited the effort of ESCUELAB PUNO and shared our last dinner together😦

fedora10Day 5:

Last day of the journey and this is the picture of the survivors and our last breakfast at CozyLucky hotel. Then we went to the port to visit the floating straw Island of Uros. The good bye was recording in a interview lead by Abadh and saying good bye to new FEDORA friends! I renewed my vows to FEDORA and GNOME as they gave more than Linux knowledge, they gave me unforgettable and unique experiences in my life!

Speaking of GNOME at FUDcon PUNO – Peru

This afternoon I did my first talk at FUDcon 2016 titled “Building GNOME with JHBUILD” where I introduced people to the GNOME project, I started with a general view of what GNOME is, and some history-related.

14753476_10208778638955836_5333068905805981813_oI have presented JHBUILD, and then some GNOME applications to starting students of UNA into the GNOME world, I presented the community and why I am feeling so engaged after more than five years of being part of the community. I also explained why I have gotten involved with FEDORA and not with other distros (which is also fine too). I was so excited about the response of the audience, they expressed energy to starting by installation of FEDORA and  more than that! They are going to try to fix bugs building first GNOME with JHBUILD. I also had the chance to promote the Outreachy program and as it is usual, I applied my method by pricing people during my presentation withe FEDORA stickers, t-shirt and pins!


Thanks to Tonet and Aly from FEDORA PERU to make the FUDCon possible

img_3955I am grateful to the FEDORA project for sponsoring my travel!🙂

Crontab on FEDORA

This is an intentional post to my students at  UNI. We are learning how to use the shell commands on Linux. The simplest example is to register the datatime in a file in my home every 2 minutes.

First, we must check if the crontab file exists. This is located on /etc. Remember that all the files that are inside the /etc directory are managed  by the superuser: root:

Screenshot from 2016-09-02 19:41:02As you see, the last line explains the way to configure “our task”. The first * character set minutes, in this case we are going to write */2:

The last line of the crontab indicates also the user that is going to execute the file “”.

Screenshot from 2016-09-02 20:03:53Besides that, we have created the sh file and we put the right permissions using chmod a+x (a of all and x of executable). Checked the list of the files.

Finally, configure the sh file starting with the header #!/bin/bash and the commands to execute our purpose.  Check the output in the file mentioned:

CONEISC2016 was held in Pucallpa, Peru and it was an event that gathered more than 1200 people. Students and professionals in the field related to the System Engineering, shared experiences and knowledge about their communities and expertises.


In the middle of the Peruvian jungle, I gave two workshops regarding GNU/Linux during six hours. The first workshop started with the History of Linux, then the introduction to the FEDORA and GNOME projects and how I was involved since 2010 and my experience through all these years. I showed them in links the GNOME and FEDORA communities.


We also celebrated the installation of FEDORA in the Lab of the University for the very first time. Now UNU has its first Lab with Linux(FEDORA). At the end, the GNOME+FEDORA party with the cake and globes were there!


The second day the students browse the usability of FEDORA+GNOME and they use the terminal to write some programs with Python. I taught the vi commands, the applications of GNOME, how to contribute and how to participated to the projects through the OPW and GSoC programs.


The online presence of Athos from FEDORA Brasil for a few minutes was so important to support me. I also invited people to go to FUDCON Puno in October 2016.


I want to thank to HackSpace for the fusion we did during the HACK CAMP 2016 to promote the FEDORA + GNOME use, so now we are able to reach more provinces to evangelize. Hope our friendship will continue as we grow up. Long life for the both projects!❤DSC03006

Thank you so much CONEISC2016 #ViveLaExperiencia

Hadoop 2.7.1 on a Virtual Machines Cluster

This time I will use FEDORA Server 24 to create four virtual machines. The first one is called “FedoraMaster”:

vm1The configuration is going to be as similar as it is in the Raspberry Pi architecture, with 1GB of memory and 16 GB of disk space and the cpu is Intel 3. The settings of storage and Network must be changed as you need:

Screenshot from 2016-07-13 03-05-41During the installation part, the interfaces must be set as is also needed:

hadoop2.7Install the package of Java and then set the Download file to store the hadoop2.7.1 installation packages and save the unzip files into the /opt file by using the tar -xvzf hadoop-2.7.1.tar.gz -C /opt/ command.

Set the path to the files .bashrc and

Screenshot from 2016-07-13 06-07-38To run it as a VMCluster, there are some considerations such as:

1.- Set the IPs and hostname, hosts and update the .bashrc and script to the hadoop environment.

2.- Add the IPs in the slave file, which is located inside the hadoop file.

3.- Change the IP on core-site.xml and create a path to store the datanode on each slave node. For more details, you can visit this Website.
