 # Klong
 - Created Wednesday 15 July 2026
 
-## J on an airplane
-
-Many years ago I learned [J](https://www.jsoftware.com/) on an airplane using an interpreter I found for the iPad. I relish long flights for this kind of thing. A few uninterrupted hours are enough to try a new language or paradigm.
-
-J impressed me with its array-oriented thinking and concision. A small expression could describe a whole computation without loops, indexes, or temporary variables.
-
-A few weeks later I understood why people sometimes call array languages "write only." The skill was remarkably perishable. What bothered me most was contextual operator overloading: a symbol could mean different things in different surroundings. Those distinctions were among the first things I forgot, and I never kept up with J.
-
-## Finding Klong
-
-About five years ago I found [Klong](https://t3x.org/klong/), [Nils M Holm](https://t3x.org/nmh/)'s small array language inspired by [K](https://en.wikipedia.org/wiki/K_(programming_language)). It had the dense expressions and whole-array operations I remembered liking.
-
-Klong also addressed my specific objection. Its syntax is unambiguous: fold, convergence, iteration, and looping have distinct spellings. Klong came with a clear [reference manual](https://t3x.org/klong/klong-ref.txt.html), Holm's book [*An Introduction to Array Programming in Klong*](https://t3x.org/klong/book.html), and a small, free C interpreter I could read and hack on.
-
-Then my family grew, and I had fewer long stretches for learning languages. I kept Klong in mind but rarely sat down with it.
-
 ## Klong in a browser
 
-Recently I realized I would use Klong more if it lived on both my phone and my computer. I did not need to port the interpreter. I could compile the C program to [WebAssembly](https://webassembly.org/) and run it in a [browser worker](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API). So I built [Klong for the Web](https://tailrecursion.com/klong/).
+I built [Klong for the Web](https://tailrecursion.com/klong/), a browser notebook for [Nils M Holm](https://t3x.org/nmh/)'s small array language. The interface works like a small [Jupyter](https://jupyter.org/) notebook: cells share interpreter state and can run individually or together. Notebooks persist locally, `.kg` files can be imported and exported, and the installed web app works offline.

-The site runs Holm's C interpreter, not a JavaScript reimplementation. A thin bridge feeds source files to it and captures its normal output. Execution happens in a dedicated worker, so stopping a runaway program does not freeze the page.
