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

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

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

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....

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?

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.

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!

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💀

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

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...

It's been 12 times that I tell Youtube that I'm actually ok with listening to videos in their original language and that I didn't need auto AI dubbing. So I'm officially canceling my Youtube premium account. Was long overdue anyways. I can't believe this is actually something people would want.

Gotta love that Excel is pushing "importing data from pictures" as one of the main sources, while importing from a formatted CSV file is considered "legacy". Non deterministic data FTW!

Baarle-Nassau is famous for its incredibly complex border with the Belgian municipality of Baarle-Hertog. The two towns are inextricably intertwined, forming a patchwork of 30 enclaves. The kids loved playing being in 2 countries at once 😛

With Claude Code becoming more expensive and more limited by the day it's time to investigate alternatives. I'm a big fan of the team behind Kilo since Day 1. Turns out they have a CLI and since it's based on OpenCode I can straight up plug it in Pedram Amini's Maestro. Let's GOO!

Had a great time at MLCon yesterday. Super happy to see the results of a program I've helped build :). Lots of great speakers, super organization, and leaving with some nice insights about platforms and AIOPS. But first and foremost, as always with conferences : Energy to ship! 🚀

Last week I gave the closing Keynote at ING's frontend summit. I've been building communities for over 10 years and for me the whole AI craze isn't about tech. It's about how much energy is creates in people, seeing them build stuff for fun, challenge each other. People are awesome, and humbling.

Hey good folks at Vivaldi, you're in the browser business so you should definitely know what Spam looks like right? What is this folks? I'm trying to become a customer and you're bombarding me daily. Do you want me gone?

Looks like I've let AI go BRRR by itself for over a day by now. Still having a lot of fun with Maestro, and finally found a way to have the time to build my side projects AND workout ^^. Give it a try! github.com/pedramami...

This is legit the most seducing onboarding strategy I've seen in the few years. Very following The good folks at Kilo Code for a little while already because of the stellar team they have. This is next level :). Talk to you soon Emilie

AI hype in a nutshell xD. "Claude Code creator open sources the internal agent, used to simplify complex PRs". "Alright, settle down everyone. The consensus in this thread is a resounding 'meh'. The community is largely skeptical and unimpressed."

Spending the weekend playing around with @pedramamini's Maestro, and so far I'm quite impressed ?! It suddenly feels like Claude and my projects are getting extra super powers. Is that what AI first workflows will look like a couple years from now ? github.com/pedramami...

There is something great about snow outside as I’m working inside. The feeling of being cushioned helps with focus somehow. Pure bliss.

Toujours un plaisir de passer un moment avec @k33g_org! On ne se voit pas souvent, mais à chaque fois on refait le monde et j'en ressors plein d'énergie et avec une grosse envie de geeker. Je veux être pareil à ton âge! La soupe a-t-elle réussi à passer la sécu de l'aéroport?

Kinda cool to think that you can have a whole functioning message broker that runs by itself in isolation for less than 10MB. Great going Mosquitto reducing that image size.

If you need any proof that Bending Spoons is just letting #Meetups die and racking in the money of large groups already existing, simply look at the constant, daily spam of bots posting the exact same message in all groups Time to switch, folks

I'm sorry Mr Excel, but no matter how much you want to keep me continuously online, importing CSV files is NOT Legacy. And I'm laughing at you every single time you tell me it is

Spec-Kit giving me commercial options for deployment. Great, given that's most likely what will happen anyways but it bears the question of how long it will take before LLMs are manipulated to be biased towards the platforms of their overlords ^^.

For years I have respected @danabra.mov's for the depth and quality of his writings and thoughts. He is one of my examples of what a technical leader looks like. But this quote genuinely made me chuckle 🤭. Dan is relocating to Japan, hire him before it's too late! overreacted.io/hire-me-in-j...
I haven’t done many publicly notable things before getting hired at Facebook, other than accidentally co-creating Redux as a demo for my conference talk.
