Yesterday I was crafting some puzzles for my girlfriends, and I was looking for letter-based ones where I a secret word would be revealed once solved.

They function as notifications you receive whenever a vulnerability affecting one of your project dependencies.

But long after receiving a notification, how to list all security alerts affecting your repositories ?

I didn't found an out-of-the box solution …

Some time ago, I used the overblog platform in order to create a blog for a long trip in Ireland.

Despite being sometimes very slow, it was overall a good platform, very easy to grasp for beginners. The blog is now old and unused, but before destroying it I wanted …

Being currently on a bike tour in Europe for several week, without computer nor smartphone, I don't have the opportunity to post much on this blog.

        raise RuntimeError('Woops')

    def __del__ …

When I migrated this blog to Pelican, I noted one thing that I missed from Ghost: tags autocompletion, to help reusing tags I already defined in other articles.

This week I discovered the fantastic glitch art Reddit community (for a little more context on glitch art, wikipedia has a page). These are the pieces I love the most (click on them to find the source):

In the last years, cmder became my default console when I needed a cmd.exe-compatible Windows console.
