Who am I

I’m Luca from 🇮🇹 and I work in the networking world since September 2017. After high-school I wasn’t sure about starting university, so I attended a Cisco boot-camp held by a local system integrator.

During my high school year I have worked almost exclusively with programming languages like Java and the web trio CSS, HTML and PHP....

Why sometimes when I configure the RRM I feel like I am touching the buttons of a nuclear reactor control plant? All this nonsense started from this r/networking article written 10 months ago.

Wi-Fi channels

Wi-Fi channels A big premise This article is a mix of what I’ve learned in the past few years and more recent studies on the RF physical layer which forced me to investigate in depth concepts like: encoding, spectral mask, Clear Channel Assessment or the Shannon limit. Stuff that you don’t have to know perfectly if you’re trying to achieve a mixed-work career oriented more towards R&S than wireless technologies and I probably won’t study them deeply myself....

Note-taking with Obsidian

Note-taking with Obsidian Obsidian is a free, open-source note-taking app which helps you link your notes to each other using hypertext with markdown files. Why I need to switch from OneNote, Google Drive or Evernote to Obsidian? You don’t. You don’t especially because Obsidian is a pain in the ass to configure and mantain a well-ordered list of notes, both useful and practical and cool-at-the-eyes, is not a simple task and I’m far from achiving it....
