I have been using Laravel professionally since almost 1year, and I must say: I’m very impressed with the framework.
Everything’s run smoothly, there’s a feature for (almost everything) you can think of, so you (almost) never need to
reinvent the wheel. 
 This is very advantageous since you only focus on building your product features by features and spend less time…
Hello friend… 
 It has been a while. 
 I have been very busy lately with work, open source and life that I didn’t find the energy to write a blog post.
Despite having some good ideas, I wasn’t really in the mood. 
 Hopefully, I now have the energy and the subject to make a good blog post: let’s talk
about Laravel and emails! 
 1. Laravel and SMTP…
I have started using a lot IRC lately since I became a Debian Developer (Debian
use a lot IRC and mailing lists to communicate). 
 For those who don’t know what IRC is: it’s basically the ancestor of modern chat messaging
like Discord . IRC is a quite old piece of technology, coming from 1988. 
 One big drawbacks of IRC is that there’s no such thing as a history,…
I have received a lot of positives feedback for my blog lately,
and I do really appreciate it and try to integrate the suggestions
to update my posts and make things better. 
 With the aim of continous improvement of this blog, I have decided (a bit late?) to open source it.
The source code is now available on Github ! 
 Feel free to open a PR if you want to fix a typo or if…
We can all agree that it’s been a quite… awkward year to say the least. 
 We went through massive fires around the globe, almost reaching WWIII, a pandemic that forced whole countries to go under a lockdown, etc…
Each event being more tragic than the others, and no one could believe what we were living. 
 And yet, we’ve made it through this hell of a year, we’ve survived 2020!…

I’ve made a little fun experiment this weekend by trying to make a unified package manager user interface.
The idea was to design the simplest package manager UI possible. And I’ve come up with something that I really like. 
 I’ve named the project ‘x’ (I am tired in finding meaningful name derive from Greek god or anything…).
Here’s how it…
I have been using Debian intensively for more than 4years,
mainly on the servers I administrate. It’s a really powerful & stable (one of the most) OS, with a TONS of package available
trough APT . 
 Debian has helped me in a lot of ways, and I wanted to bring something in return, even the little help I could offer.
So, one year ago I have emailed a friend who is also a DD ,…

As my dev workstation is running Ubuntu, I have recently started using Snap 
to install most of my applications. 
 Snap is an interesting packaging approach since it allows applications publisher to release new versions
directly without having to involve distribution maintainers. This reduces the delay between application development
and end users deployment.

 I have done a little security audit on a friend VPS last week, he was providing Docker runtime
to some people, with SSH access, and wanted to know if his setup was secure. 
 By default, docker only allow to run command as root user, in most case this is not desired since giving
root access equals…
I used to manage a dozen VPS since many years: Zabbix, Gitlab/Gitlab CI, private docker registry ,
production environment (3 nodes docker swarm cluster), database server (MariaDB & MongoDB),
blog server (running Ghost ), logs collector ( Graylog ), etc… 
 I was spending a consequent amount of money & time for all these VPS, and it was time to change. 
 
 From Ghost to…
I wanted to write a quick off-topic article about the ongoing coronavirus pandemia since there’s a lof of false opinions and fake news on this topic. 
 This virus (SARS-CoV-2) is deadly and not really comparable to the flu, it is at least much more contagious. (We don’t know anything about the death rate yet, since the pandemia is ongoing). You shouldn’t treat it lightly.…
We’ve been experiencing very strange memory leak in our Java application servers at work: when deploying new version of a micro service, the JVM process was running out of memory and consequently crash leading to service outage. 
 After a bit of research, it looked like that these kind of errors were very common with this application server, especially when deploying application without…
I have written an article on the provisioning of a Docker Swarm cluster from scratch and I have received a lot of comments stating that docker swarm is dead and that I should be moving to Kubernetes instead. 
 What happened to docker? 
 For those who were not aware, Mirantis (a cloud provider) has bought Docker enterprise in nov. 2019. Just after that, Mirantis has written a blog post to…
As you may already know, I have launched, with a Friend, an Android application to customize phone wallpapers randomly. The development of the app itself only took us 2 months and was quite fun. The release was really exciting and the first feedback from real users was encouraging. However, things didn’t go as planned…

Since I have containerized my whole develoment workflow, from testing to production, I needed a docker registry to centralize my private images and ensure their deployment. I didn’t wanted to use Docker Hub or Github Packages because the images would be publicly available. Therefore I have started searching for existing private registry providers…

One night I was feeling inspired and decided to read again all my favorites quotes on Google Keep while listening to music. And suddenly an idea just popped into my head: why not make a little mobile friendly application to view my quotes properly? 
 And that’s where it started…
