# It's not about having a backup, but being sure the backup works

Since I discovered BorgBackup (short: Borg) I have felt way more confident about my backups. Borg gives you a space efficient storage of backups, data is saved encrypted, and you get good versioning of backups. I solved all my previous inconveniences when just using rsync. I lacked the way to keep track and order different versions. Compression and encryption as a great plus even when I just keep my backups locally.

# Participating to my first hackathon

I’m currently looking for my next life project and to figure it out I trying a lot of stuff. To that goal I’m getting involved in as many things as possible. Last week, I went to the Innolabs healthcare hackathon in Berlin. It was quite an awesome event and I learned a lot from it. I never really worked on the health sector before, thus it was a nice introductory experience.

# Org-CV an Org export backend for CV

I’m again in this time of my life where I’m looking for a new long term project to work on. Because optimization is my favorite way of procrastination, instead of just making a Curriculum Vitae (CV) for job applications, I decided that I need to implement an org-mode export backend. This backend will let me keep my CV in org-mode and then export it to $$\LaTeX$$ or markdown for my website.

# A year on my cloud

It has been a very complicated year regarding my cloud services. I started completely unaware of the difficulties, and it has been a fun and painful ride. The fact that there are projects aiming to provide personally controlled cloud services is great. The fact that there is people being paid for doing this kind of work for companies means that it ain’t that simple to manage. I encourage to try the sovereign project, which assists you in building and maintaining your own private cloud.

# Visualizing a Bethe lattice

During my PhD I always wanted to have an interactive way of plotting a nice looking Bethe Lattice and particular to my work a Dimer Bethe lattice. Because this visualization wasn’t an essential part of my research I never investigated into it. It is enough to draw them on paper for any practical purpose. I was then confronted with my PhD oral presentation, great opportunity to procrastinate and get the nice unessential plots done.

# Git diff images and pdfs

Git is a fantastic tool to version control code. And the advantages of version controlling my work are so evident that I want to version control everything else I do besides code. Most of my work consists of editing text files, and I have even forced my workflow into text files just to be able to version control more of it. Thus, I keep track of my source code, org-mode notes and then some $$\LaTeX$$ files.

# Moving to Hugo and GitLab pages

I’m guilty of having an online blog and not writing on it. I must confess that working on its looks and internals is much more fun for me than actually putting some words in plain English for everyone to read. But that is not the point, the content is the point of a blog. This website has gone few visual updates over the years. Each time I decide to embrace new technologies(at least to me) and to work on top of somebody else’s work instead of trying again to do the design by myself.
