Ibex can also be used as a standalone language through a REPL, notebooks or compiled to C++. The R Ibex package is significantly faster than dplyr and faster (more than an order of magnitude faster in 5/33 tests) than \[ \] ## [Ibex: Tables at the speed of thought](https://bobjansen.net/ibex-tables-at-the-speed-of-thought/) _2026-07-30 · BobJansen · Bob's Blog_ Ibex is a new table focused language for analysis of tabular data and time-series. Its goal is to combine the conciseness of data.table with speed, obtained by native code generation, a fast interpreter and lots of attention for efficient algorithms and code. It aims to make exploratory queries quick to write and fast to execute. \[ \] ## [Ibex: A Typed DataFrame Language with C++ Code Generation](https://bobjansen.net/ibex-a-typed-dataframe-language-with-c-code-generation/) _2026-02-22 · BobJansen · Bob's Blog_ Anthropic used a swarm of Claude Opus 4.6 agents to build a C compiler for about $20,000 in API costs with minimal intervention. It did make me realise that while I have been a happy user of R s data.table for quite some time, the time to build something better is here.

The source is on GitHub. Almost all of the code by Claude, the idea and bugs or by me. What is it? The playground lets you write, assemble, and run MMIX assembly code directly in your \[ \]
