github-linguist is a Ruby library and command line tool for detecting the programming languages used in a project. It is used by GitHub to detect the language of a project and to generate language statistics.

We can use it through the command line, in order to analyze the programming languages used in a project.

During my application to bioinformatics master degree, I had to say which programming languages I commend. So here is some quick tips to use github-linguist as I learned to do for this purpose.

Il suffit d’installer xclip:

sudo dnf install xclip # sur fedora par exemple

Puis, c’est tout simple:

echo "Coucou !" | xclip -selection c

Un exemple d’utilisation: copier une clé publique ssh dans le presse papier depuis le terminal:

cat ~/.ssh/id_ecdsa.pub | xclip -selection c

Durant les trois années de licence bioinformatique, nous avons des cours de biochimie, et ceux ci viennent avec leur lots de structure chimiques à connaître.

En L1, j’avais réalisé un document pdf avec LaTeX/chemfig des acides aminées protéinogènes en représentation de FISCHER, et j’avais trouvé ça plutôt sympa, bien que ça m’avait pris pas mal de temps à rédiger.

Ajourd’hui, j’améliore ma méthode: fini le code de la structure en chemfig (extension LaTeX) a la mano, vive le code généré par du code !

Some years ago, I had the opportunity to create a camera trap based on an Arduino board. The goal of this project was to capture photos of wild animals, and to have fun with electronics and programming.

At the time, I created a website in html, to present the project; but I can’t find the source code anymore… That’s a shame.

I will try to present this old project again, hoping that it may interest someone.

Sharing folder between KVM virtual machines and host, may be useful. Here is a way found in fedora forum.

Quickstart

Change vm to your vm hostname.

sudo mkdir -p /mnt/shared
sudo chmod -R a+rwX /mnt/shared
sudo semanage fcontext -a -t svirt_home_t "/mnt/shared(/.*)?"
sudo restorecon -R /mnt/shared
tee fs.xml << EOF > /dev/null
<filesystem type='mount' accessmode='mapped'>
<source dir='/mnt/shared'/>
<target dir='shared'/>
</filesystem>
EOF
virsh shutdown vm
virsh attach-device vm fs.xml --config
virsh start vm
ssh vm
sudo mkdir -p /mnt/shared
sudo tee -a /etc/fstab << EOF > /dev/null
shared /mnt/shared 9p trans=virtio 0 0
EOF
sudo mount -a
