From coding all day to managing features in hours 🚀 Maestro lets AI agents build in parallel while YOU stay in control. #AIAgents #DeveloperTools

From Assisted to Orchestrated AI Development using Maestro
My experience with Maestro, an AI agent orchestration tool. By combining spec-driven Auto Runs with a feedback loop, it transforms the developer role from writing code to managing features.

So many people worked so hard, I loved seeing something I hadn't experienced in that way yet : A palpable buzz, an ING Tech identity. Can't wait to see what next year will bring! 2/2

Last week was ING's internal #Tech Fest! After months talking about it, and helping curate the content it was amazing see it come to life! Great to meet colleagues of all horizons, and share the 1ES story. 1/2

First time playing DnD with the kiddos :D. 10 year old went for a Paladin, while the 5 year old went full pyromancian. Why am I not surprised xD

AI-assisted genealogy
My son recently came to me to brag about using AI to find our ancestors. While the results were correct, I didn’t learn anything new, as it stopped at my grandparents. I was never very interested in m...

I've been diving a bit into geneaology the past year, in my free time. My family tree gets pretty complex very quickly... And last week I read an article from Nicolas on how he uses AI to do this. I hadn't thought about it. Results : 250+ elders found in a couple days. Passionating, so TY Nico! <3

And this feels very different from past technology jumps. Kotlin, Automation, DevOps: each of those made my work feel lighter. AI makes it faster. I'm not always sure it makes it lighter. Am I the only one here? #devex #devrel 4/4

Julien Lengrand-Lambert 🥑👋 @lengrand.fr · 23/09/2026
I look forward and much of what I observe is that there is actually more work coming on my plate overall, not less. The capabilities of AI allow me to do things faster than ever now, sometimes I just have to stop to wonder if I like what I'm doing though. 3/4

If we give everyone playing soccer a personal trainer and everyone is going faster and getting much better, is the sport as a whole improving? And more importantly, is it still as interesting and fulfilling for the athletes? 2/4

AI companies business case is about people productivity raising. And gosh I make use of AI every day. But if everyone's productivity raises as much, is anyone getting ahead except for Anthropic and co? 1/4

So far the only change I've seen from trying out Linkedin premium for a month is an alarmingly increased amount of spam. Multiple daily emails, each providing exactly 0 value. Pretty sure what my next step is.

I wrote about #maestro, an agent orchestration application in the last 🇳🇱 #java magazine. Happy to do a nice shoutout to an app I've been using extensively the past year, and helped me get better at using #AI for my side projects. It even made it up the cover :P

Julien Lengrand-Lambert 🥑👋 @lengrand.fr · 03/09/2026
Thanks for the answer. Things are indeed a bit better, but still not solved :). But at least I managed to get past the AI wall now, so hopefully I'll get some support soon.

I literally have a gaping hole in my garden which I'm waiting to know if I can close, I have a non functional battery in my backyard that isn't functional and you want me to pay up? Would you please do better? I just want to talk to a human to know what's happening....

Julien Lengrand-Lambert 🥑👋 @lengrand.fr · 02/09/2026
Folks @zonneplan.bsky.social . I love you guys, been a customer for a while. You came install a battery monday, it never connected to the app. No way to contact anyone human, your Kiki AI keeps hanging on me and giving me wrong info. But you do send me the bill ? 8 DAYS? What is happening here?

Reading this again, I wonder why I felt the need to indicate the lamp looked like a rabbit 🫣

Julien Lengrand-Lambert 🥑👋 @lengrand.fr · 02/09/2026
I'm using #AI every day, and I think I know its capabilities very well but sometimes I'm still surprised. My daughter's lamp was broken. Sent a photo about the circuit to #Claude, who directly told me the cable was at fault because of a missing resistor. Color me impressed.

I mean, if I have to go that path, I'll just revert back to using icloud / the git community plugin. I just _really_ find it a shame, because I WANT to pay. And I'm clearly not the only one there's threads going back 2021 on the forum : forum.obsidian.md/t/obsidian-s...

Obsidian Sync - Sync hidden files and folders as well (start with a dot)
I do not understand how this is not implemented yet. I became a paying customer yesterday, only to realize that because of that limitation all of my AI setup does not work. I have no other choice but ...

I can absolutely hear ignoring things like .git by default, but all .dotfiles? I just don't really get it :S.

Julien Lengrand-Lambert 🥑👋 @lengrand.fr · 18/08/2026
Hey beautiful @obsidian.md folks. I love your product, and I'm definitely the only one. Why are .dotfiles not synced in Obsidian Sync? You're the default for most AI setups. How can it be that .claude, .codex, .... are all unsupported in your official sync paying feature? Please take my money <3

Started #bouldering again after having to stop for 2 years due to an injury and I can't use Apple Touch ID any more. A detail I had forgotten 😅.

Julien Lengrand-Lambert 🥑👋 @lengrand.fr · 08/07/2026
Agreed, and also wondering if it will ever come back. Have been considering leaving it all together for a while, and started investing in IRL communities more again; but where to spread larger things again if not on Social Media 😣

It's always surprising to me how the solution "work's been exhausting today, I don't want to do sports" actually is "go do sports regularly anyways, because then work is less exhausting". Body first, mind follows. Have to reteach myself that once in a while.

Between the Spam, the constantly higher prices and the lack of actual valuable features; I think it might actually be time to let Meetup go. Especially since the market has good alternatives with traction those days. Farewell, you've served the community well but it's just time to let you go!

Nugget of wisdom about learning from HackerNews today : "One thing I wish this emphasized more is that adults often confuse learning with consuming material about learning, which is why my useful rule has become: if I'm not producing errors, I'm probably not practicing yet"

Ordered a new screen and the order has been blocked in "processing" for the whole week. Delivery date promised showing Monday on the website. Support says "usually happens within 3 days". After 3 days, orders from another shop. Same story. Now having 2 screen orders in limbo mode. Curse is real💀

We're planning to watch the 🇳🇱 game tonight together with the kids, and I feel like going through this day without knowing the outcome yet will be like walking blindfolded through a minefield 😅. Here's to hoping!

Color me surprised :). Turns out somehow my info is part of the main models training data. I expect most of us to be. What is more worrying though is that there are some serious hallucinations going on. How many people think I'm actually a politician ? 😊 www.intheweights.com

I'm looking into doing some redesign in my house and we've reached the point where there's so much AI online that I can't see any more what's possible to build and not. Another year and I bet there'll be a space for AI free content locations. AI has good use cases, this doesn't feel like it

Past the announcement itself, which looks pretty interesting what I find most insightful is that this new tool making #1 on HackerNews today announces support for #kotlin, while #Java is not even mentioned. I think it's a first? Is the landscape changing for good? www.iroh.computer/bl...

So I've spent some time yesterday creating a Claude skill to do market research for all my little app ideas and rank them by opportunity. After looking at 250+ ideas the one that ranks highest is an app that uses AI to do market research for all little app ideas and rank them by opportunity 😅.
