Yes, computers helped to crack the enigma (we did hear about that at length) but also greatly supported the Nazi regime, for example by selling 1.5 billion punch cards and corresponding machines for censuses. How can it be that CS never discusses this history? www.felienne.nl/2026-10/#tec...

Last night at SAP HQ in Walldorf I first tested the development version of a new image composition extension for Snap! out in the wild with our campus ambassadors. Try it yourself! snap.berkeley.edu/versions/dev...

I’m super excited about making first-class-ness first-class in Snap! v12: Create abstract data types (ADTs) and domain-specific languages (DSLs) with dynamic, graphical widgets for data structures ranging from fractions and shapes to melodies, data bases and neural networks.

Some pictures from our workshops during @fosdem.org junior.

I loved the energy in the Create‑a‑Critter workshop at #FosdemJunior #fosdem Children explored @turtlestitch.bsky.social coding and decorated a colourful range of imaginative critters (with a little help from their parents). @fosdem.org My #TurtleStitch resources: www.warwick.ac.uk/turtlestitch

Kudos to the #FOSDEM team, my talk “Deep Learning Demystified - Having Fun with Neural Networks in Snap!” from last Sunday in Brussels is already online: fosdem.org/2026/schedul...

Heading to #FOSDEM this weekend? I’ll be giving a talk about neural networks in Snap! on Sunday in the Educational Devroom and hang out with kids and teachers at @fosdem Jr.: fosdem.org/2026/schedul... Don’t hesitate to approach me to chat about Snap!, blocks programming or the state of CSEd!

Scheme, the ur programming language, is 50 years old, as Jason Hemann just reminded me.

Look, Ma: The latest issue of @acm.org INROADS Magazine features an interview with me. It’s open-access, so you can read up on my incoherent blabberings and old-dude anecdotes about block based programming & friends. dl.acm.org/doi/abs/10.1...

Snap! is now accessible in 48 languages. Thank you, Serge Faure, for contributing the Vietnamese translation as latest addition over the holidays! Now live in v12 beta: snap.berkeley.edu/versions/dev...

Render unto Casar! Turtle geometry with a twist: Let sprites draw, stamp & write onto each other. Coming to Snap! v12 next year. Play with the beta now: snap.berkeley.edu/versions/dev...

Another incredible use of this tutorial is classifying 25 notes on a piano. Using a 450-50-26 model (I include a backgrounds sample), the results are mind-boggling!! In the list I show the note and how many times out of 331 samples it is predicted. My testing method is in the video. Next I need 1/2

I’ve been quite excited this past 10 days as I have been able to get this working for me to classify sounds astoundingly accurately. I only want to be able to do any three sounds to work with young children, however I’ve tried 26 classes and it still works flawlessly! Thanks for all you do!

How does generative AI work? Check out our materials, watch the video, read the paper, play the unplugged game, and program along in Snap!: community.sap.com/t5/sap-unive... included: Transformers, word-embeddings and cool stuff from our friends at SoekiaGPT and Bootstrap

'tis the season to turn on "Santa Hats" and "Bake your own blocks" in Snap! beta: snap.berkeley.edu/versions/dev

Here is a godawful joke in chart form to ruin your Christmas season 🤪🎄

What if you could seamlessly zoom in and out of the Snap! IDE while editing and running a project at the same time? That's what I'm currently working on, now online in beta-test for intrepid early adopters: snap.berkeley.edu/versions/dev

What is #softmax and why is it important for machine learning? Check out my refresher tutorial on multiclass classification in neural networks and how you can build your own from scratch in Snap!, (or) your favorite programming language: snap.berkeley.edu/project?user...

To say this is a problem is a gigantic understatement. We live in the golden age of AI slop. Hopefully we will soon gain the right control the algorithms that control our online life in order to filter out AI slop to a large degree.

New Blog post. microblocks.fun/blog/2025-10...

Last week I was asked to explain to the SAP dev community how neural networks work using Snap!. From matrix multiplication to backpropagation, from perceptrons to deep learning, from Heaviside to Hinton, here's the math and the history in a nutshell: www.youtube.com/watch?v=_JSn...

Need to teach about machine learning and neural networks? We propose a “Chalktalk” activity: Train a local neural network to classify a bunch of hand drawn figures. Then use it to animate your own interactive story! Snap! project starter: snap.berkeley.edu/snap/snap.ht...

I have just updated Snap's neural networks extension with the capability for multinomial classification. You can now generate a block that directly reports the class name of a sample record for data sets with three or more categories. snap.berkeley.edu/run

Join me online next Thursday to find out about the “sales slip algorithm” that powers all of contemporary AI, the history of neural networks and how to build them yourself using Snap! This talk is part of SAP’s #Devtoberfest and open to everyone. community.sap.com/t5/devtoberf...

It was such a pleasure to welcome Mark Guzdial at SAP today, learn about the latest University of Michigan PCAS developments and discuss CS pedagogy wrt neural networks in Snap. Thanks for bringing your ukulele, Mark! You saved my live demo to train a neural model to distinguish musical instruments!

I will be in Tokyo, Japan, from Sep 24 - Oct. 4 for the NII Shonan Meeting #233 (shonan.nii.ac.jp/seminars/233/) with a few days before and after. If you’re around and would like to chat about Snap! / educational blocks based computing DM me!

I have just now released Snap! v11, featuring an alternative way to build your own blocks: Instead of writing an algorithm you can let a neural network figure it all out directly from a dataset of examples. Can't wait to show y’all next week at SnapCon in Heidelberg! snap.berkeley.edu/run
