https://kuty.sh Thoughts from a tech founder, Torah supporter, and lifelong learner en-us Tue, 27 Oct 2026 13:50:46 +0000 https://kuty.sh/engelmanns-crutch Walk into a Direct Instruction classroom and the first thing you notice is the rhythm. The teacher asks a question. Pauses. Says "get ready." Snaps her fingers. Thirty kids answer in unison. Three seconds later, another question. Another snap. Another chorus. Ten responses per minute, per kid, for forty minutes straight.

A family with three kids is spending more than a mortgage. And what do they get for it? A system that, by its own community's admission, can't teach kids to speak Hebrew after twelve years of trying.

Refreshing case counts, reading every hot take, tracking every policy shift. When October 7th happened, it was worse — scrolling Twitter for the accounts that actually had real info, cycling through non-stop WhatsApp groups, some of which turned into sending money and supplies. It felt like I was doing something. Tue, 31 Mar 2026 00:00:00 +0000 https://kuty.sh/skip-the-news-read-the-analysis https://kuty.sh/claude-code-mobile I run Claude Code from the back of an Uber. From the couch. From anywhere I have my phone. It's the same full CLI I use at my desk — same context, same projects, same session I walked away from an hour ago. There's something freeing about being able to partner with Claude on whatever you're working on, wherever you are.

At his bris, I told our family why. I was honoring Rabbi Fohrman's analysis of chapter after chapter of the Joseph story. Joseph the dreamer. Did his brothers really sell him? Why didn't he send a letter home to his dad? Was civil war averted by Yehuda confronting Joseph? And many, many more echoes before and after.

She's terrible at it. She keeps failing. But when she stops trying to be him and starts doing magic her way — messy, instinctive, rooted in who she actually is — she becomes more powerful than he ever expected.

That means 30% of the material — the concepts, the connections, the building blocks — didn't land. But the system doesn't care. The class has to keep moving.

In a traditional school, I know exactly what happens next: a warning, then a consequence, then the principal's office. The system has one tool — compliance — and when it fails, the kid gets labeled.

That's what American Jewish institutions have spent trying to teach their children Hebrew over the past century. The result? Cole Aronson, writing in Mosaic, estimates that roughly 3% of day school graduates can hold a Hebrew conversation. After twelve years of schooling.

I'm sitting uncomfortably in the back seat of my parents' rental car as my father drives through the hills of Jerusalem. I can smell the dry dusty air. I'm staring through the windshield at the dirty roads. And most importantly I'm trying to ignore what my father is saying.

The off-the-shelf solutions force you into their model of how work should happen. But that's not how minds actually work.

I landed a job at Price Waterhouse--one of the top firms at the time. Out of 30--40 Yeshiva University grads who joined the "Big Eight" firms that year, only three of us made it to Price. I was proud. I was also way too full of myself.

The redemption arc of a verbally abusive spouse to a loving one revealed to me how accepting I am of harsh language in the name of truth and practicality.

The spy story is an excellent canvas to examine how ultimately what we believe is subjective and actually rejects an external truth. Wed, 01 Jan 2025 00:00:00 +0000 https://kuty.sh/black-dove
