My review of the Centri BTL1 certification
At the end of last year, my employer offered me the chance to prepare for the Blue Team Level 1 (BTL1) certification run by the company Centri. It’s not necessarily the one I would have picked on my own, but you should never turn down the opportunity to add a new certification to your CV 🙂 To give you an idea of my level, I made a career switch to become a SOC analyst and I had 18 months of experience in a SOC when I took this certification. Here’s my feedback. What is the BTL1? The BTL1 is a certification aimed at junior blue team analysts, covering six domains:…

My Current Favorites – [July 2026]: My First Software, The Dream of the Red Chamber
Happiness is doing something for fun, spending hours on it, without getting paid 😀 Of course, if it paid, that would be even better, but if you enjoy an activity so much you could spend all day on it without pay, for me, that’s THE happiness. The Dream of the Red Chamber Lately, I’ve had almost unlimited AI use to translate whatever I want. I really liked the novel The Dream of the Red Chamber and as I told you last month, I reread the novel, and I thought maybe I should get into Redology to better understand the book. I sent tons of analyses/books/videos on the subject to the…

How I created my very first Windows .exe software with Claude Code and Codex?
It’s been two months that I’ve been vibe-coding, first with Claude Code and then with Codex CLI. Lately, I had a bunch of tokens to spare and few projects, so I took the plunge, just for fun, into creating a tool that lets you listen to documents as audio and annotate them at the same time (a mix of Audible and Kindle). In the end, it turned out to be really useful: my parents, whose eyesight has faded quite a bit, really need it to have AI read books aloud to them. I decided to make the Windows software version (a simple .exe) so they could install it on their…

[Reflection] #40: Why Raising Your Risk Threshold Is the Key to Freedom?
I recently read an article by Noah Hawley in The Atlantic, which recounted his visit to a private gathering organized by Jeff Bezos in 2018. The guests arrived by private jet (paid for by Jeff Bezos), each of their children was looked after by a nanny (paid for by Jeff Bezos), and in their rooms awaited luxury bags filled with luxury products as gifts. He writes: The closer I get to the world of wealth, the more I understand that being truly rich doesn’t mean amassing enough money to afford superyachts, private jets, or a million acres of land. It means that everything effectively becomes free. Any good can be…

How to extract your reMarkable highlights and send them to Anki? [AI prompts & github]
On Kindle, you can very easily export highlighted passages, but that’s not the case on reMarkable. I used CODEX to create a local web interface where I can select my reMarkable files (epub/PDF), extract the highlights, and send them to Anki. Here’s the interface: You can see that you can: Everything is exported directly to ANKI via Anki Connect. You just need the Anki app installed and open on Windows. Then, the decks will be synced with Ankiweb. For each card, you see the highlighted passage on the front, and on the back, its context (one sentence before, one sentence after). If the same file has new highlights, the old…

Already 3 months in Tahiti! (French Polynesia)
I’m going to do a quick check-in at the quarter mark of our Polynesian adventure to tell you what’s happening in Tahiti right now. Why do I say “quarter”? Because JB decided to extend by a few months our stay in Tahiti. Nine months (the initially planned duration) didn’t seem long enough to fully enjoy this paradise, so we’re staying two extra months. In 3 months, we haven’t had much time to travel after all. On weekends, we stay in Tahiti; there was a little tour around the island, a round trip to Moorea , and 6 days of vacation. Since we already live in a vacation spot, just a…

5 Days in Moorea (French Polynesia): Dolphins, Rays & Sharks
We take the ferry to Moorea in the middle of the afternoon. We’ve been to Moorea twice (the first time 10 years ago and the second time for a scouting trip two months ago), but this is the first time we’ve brought a scooter with us. Our itinerary spans five days, but you can do exactly the same thing in two days. Part 1: Travel JournalPart 2: Practical Tips Part 1: Travel Journal Day 1 For the ferry ride, we were told that scooters don’t need a reservation, but cars must book in advance because there aren’t many spots—especially for the last daily ferry between Tahiti and Moorea. Many people…

Our stay at the Intercontinental Resort Tahiti (French Polynesia)
Our Airbnb in Tahiti being booked for a few days by someone else, we take the opportunity to go on vacation. Even though we now live in Tahiti, you can still “go on vacation” while staying on the same island, because according to a buddy we’re “already living on vacation” 😀 We chose Intercontinental Resort Tahiti because it’s the best hotel on the island. Part 1: Travel JournalPart 2: Practical Tips Part 1: Travel Journal We’ve been here several times before, once with a pool pass and other times for lunch, but this is the very first time we’ve booked a room. And frankly, in the low season, it’s more…

[Analysis] Dream of the Red Chamber vs. In Search of Lost Time
Last month, I told you about the four great classic novels of China, including Dream of the Red Chamber. Reading expert analyses from the Redology (a literary branch that analyzes only this novel), I realized this book had a lot in common with In Search of Lost Time by Proust. That made me very happy, because I know that the Dream of the Red Chamber only exists in French in Gallimard’s Pléiade collection (in other words, the books are expensive). Reading it is demanding for French readers, as it requires an excellent understanding of Asian culture, as well as Chinese wordplay. However, if this novel resembles Proust’s, you can at…

The 5 most incredible places in the world
There are places you visit because they’re “must-sees,” because they’re in every guidebook, because you’ve seen 10,000 photos of them on Instagram. And then, once you’re there, something unexpected happens. It’s not just beautiful. It’s not just impressive. You really feel like you’re no longer in the same world. That doesn’t happen to me very often, because after traveling so much, you become a bit picky. It takes more than a pretty landscape or a famous monument to move me. It takes a special energy, a light, a feeling of vastness, and above all, a desire to go back. So here are 5 destinations that really left a mark on…
