Home network modifications

Soon to be moving to a new region, I took the opportunity to thoroughly review my internal network. Indeed, it had been designed during my studies, and modified afterwards. This architecture had reached its limits, and overlapping between VLANs prevented major modifications. Having outsourced my website, and having decided to do without my Cloud server, and other application servers that I don’t use anymore, I was able to stop my ESX, as well as the Read more…

New website

he old website had become dated and, I admit, being written in pure HTML, it was nearly impossible to update. Each modification required indeed to connect to the server, and to modify the HTML code by hand. An important decision was therefore made: Completely change the site This idea had been floating around in my head for some time. Done on this day of Tuesday, August 10, day of the production of this new site. Read more…
