Upgrading from Jekyll to Ghost

I have already explained in my last post [https://lengrand.fr/goodbye-github-pages-welcome-ghost/] the reasons for moving away from Jekyll [https://jekyllrb.com/] running Github Pages [https://pages.github.com/]. This post describes the steps I took to move everything over to Ghost [https://docs.ghost.org/setup/], focusing on the

Goodbye Github pages, welcome Ghost!

The last days, I finally set myself to something that was long overdue! After years using Jekyll [https://jekyllrb.com/] hosted on Github Pages [https://pages.github.com/], I decided to move away from it and am now using Ghost [https://ghost.org/] on a Digital Ocean droplet. I originally

Automating the activation / deactivation of Spotify's proxy settings

I'm a BIG fan of Spotify [https://www.spotify.com/]. I use it every day, hours on end. I like the fat client though, I find the web version way too buggy and unstable. At ING, we use a HTTP proxy and I have configured Spotify to go

Playing around with Google Maps and Puppeteer to track parking lots

Over the last weeks, I have been reading quite a bit about Geomarketing [https://en.wikipedia.org/wiki/Geomarketing] and have been searching for fun experiements to do. One of my ideas was to check how many of the largest Carrefours [https://www.carrefour.fr/] in France has open parking

My experience at the 2017 Polymer Summit

Last week, I attended my first conference ever : The 2017 Polymer Summit in Copenhagen. I am used to go to Meetups (and organize them myself [http://meetup.com/Saturday-Morning-Coding-Utrecht]) but it was my first time taking part in something at a bigger scale. Since I joined ING [http://ing.nl]

Starting a new adventure

After 5 years spent working at Spacemetric [http://spacemetric.com/], I finally decided to move on. The last years have been great and it's insane how much I grew. But I also think it's important to move when you start feeling too comfortable somewhere. That'

Cloning a workspace in Jenkins with a Git SVM setup does not checkout the correct branch.

Hi there, This is a strange behaviour I have noticed when using Jenkins lately, that caused us a few headaches before we realize what was happening. At Spacemetric [http://www.spacemetric.com/], we are using both Gitlab and Jenkins for CI. * Gitlab [http://about.gitlab.com/gitlab-ci/] is used to

Hey there, Today, I downloaded the latest version of ffmpeg and trid to compile it from scratch.

Merging several SVN repositories into one

The source code at Spacemetric [http://www.spacemetric.com/] has been split over several reasons for years. The main reason was that some customers were having access to part of our code, while some other parts were to be kept private. This makes working with branches a real nightmare, and

Hey all, Note: The solution mentioned in this article is not functional any more after all the amazing changes that Mr. Elno brought to Twitter (😖, I mean X 🤢). There is no way to embed your timeline like this any more without paying. 🤷‍♂️ This week-end, I worked on integrating a social
