New horn-related blog post: Hazel's Practice Wheel A tool for randomly selecting from a variety of practice techniques. steveeddins.com/blog/horn/ha...

On the left, a colorful spinning wheel can be used to select from a variety of practice techniques, such as "half tempo," "flutter," and "F horn only." On the right is a screenshot of a web page version of the wheel.

New blog post: History of Image Display in MATLAB, Part 5: 1997-1998, MATLAB 5, and Image Processing Toolbox 2 "MATLAB 5 saved image processing in MATLAB." At long last, I have continued my series about the evolution of image display in MATLAB. steveeddins.com/blog/matlab/... #matlab

HUBBLE PROBES THE COMPLEX HISTORY OF A DYING STAR

This NASA Hubble Space Telescope image shows one of the most complex
planetary nebulae ever seen, NGC 6543, nicknamed the "Cat's Eye
Nebula." Hubble reveals surprisingly intricate structures including
concentric gas shells, jets of high-speed gas and unusual shock-induced
knots of gas. Estimated to be 1,000 years old, the nebula is a visual
"fossil record" of the dynamics and late evolution of a dying star.

I just saw the New York Times obituary for Cleve Moler. I noticed that the reporter who wrote it posted a wonderful note in the comments section just below the article. Here is a gift (paywall-free) link to the article: www.nytimes.com/2026/06/11/s...

A comment posted by obituary reporter, Clay Risen: "One thing you won’t often see us do in obituaries is talk about whether someone was kind (or a jerk). It’s subjective, and usually irrelevant to their significance. But over and over I heard how kind Cleve Moler was. I’m so glad to see that reflected in the comments."

New blog post: IMVIEW v4 Version 4 of imview, my replacement for imshow, supports the Live Editor, improves the positioning of the zoom-level display field, and changes the required MATLAB release to R2026a. #matlab steveeddins.com/blog/matlab/...

Screenshot of the IMVIEW image display function in MATLAB, showing a highly-zoomed-in view of image inside the Live Editor, with individual pixels showing large enough to be displayed as small squares of constant color.

I read about this and had to try it myself. This is a screenshot of my phone after running the search “oreo spelled backwards” directly on Google. Check out the “AI” response.
