Perhaps, for reasons, you would like to make text you write more expensive for any LLM to ingest. May I introduce adversarial tokenmaxxing: alex-parker.github.io/tokenmaxxer/ Increase the tokens needed to represent any text by 3-6 times. It seems that l33t may have been ahead of its time.
A screenshot of a web interface showing an input text field containing a Tolkien quote highlighted roughly word-by-word in colorful blocks, and an output field containing the same text with l33t-speak style conventions, and colorful blocks highlighting character by character.

Presented at a shellfish growers conference today — a first for me. Showed our results of mapping the 3D dissolved oxygen distribution around a working oyster farm with one of our little robot boats, seen here at work with wildfire smoke and White Rock BC in the background.

Listen, folks, we can usually give advice to prepare you ahead of time for emergencies. But no one could have predicted 250 MILLION BEES would be loose on a road. So, stay away. Just…. Don’t go anywhere near them.

Cool, just now learning that the abstract that I published in 2020 on a low-cost tactile interface to enable sidewalk astronomy experiences for the blind and low vision was removed from the archive to preempt concerns about appearing too DEI.

Last week I took an outrigger canoe out from Hilo Bay to record Humpback whale vocalizations with a pair of towed hydrophones I built late last year. Their voices travel astonishingly far underwater, and even with no whales in sight I could hear multiple individuals singing.
