Pannellum 2.5.7 has been released, to patch an XSS vulnerability, CVE-2026-27210, primarily affecting the standalone viewer. As the flaw is actively being exploited for cryptocurrency-related phishing, anyone hosting the HTML file is strongly recommended to update immediately.

I built a kite for aerial photography at the South Pole: https://t.co/86BJ3zaOlb

For this past week's @BICEP_Keck collaboration meeting, I baked Chessmen-style butter cookies with Antarctica themes, CMB polarization themes, and BICEP themes: https://t.co/Zty602NAvO

@manodeepsinha @CLASS_telescope Yes, the CMasher colormaps, along with Peter Kovesi's colormaps, Fabio Crameri's colormaps, and the cmocean colormaps are all good resources.

🙉 Hear ye, hear ye! 🙉 Our new paper "CLASS Data Pipeline and Maps for 40 GHz Observations through 2022" is now on the arXiv! 📡Maps etc will be released with the upcoming companion paper on power spectra and map components. 🌐#NSFfunded 🤓

Congratulations to @SPIDER_CMB and @NASA CSBF on a beautiful launch!

I baked a blackberry pie with a spiral-galaxy-shaped inset (which won second place in a @CenterForAstro baking contest earlier this week): https://t.co/03MAmL8U7E

The recording of my #SciPy2022 talk on developing accessible, aesthetically-pleasing color sequences for data visualization was posted earlier this week! https://t.co/blFHTh4Sei

@DJSnM You missed running into Bob Wilson by two days. The antenna itself still functions (although with modern motor drivers and an empty receiver cabin). https://t.co/lafk7tuoK7

I decided to build myself a coffee table with a @NASAHubble image of the Tarantula Nebula epoxied below the glass: https://t.co/GWkGrZYxcb

@AddisonGraeme @zackli @cosmic_mar It doesn't help that the one time I posted in the Julia Discourse, some of the responses were less than welcoming.

[Matthew Petroff @petroffm]

@AddisonGraeme @zackli @cosmic_mar The other thing to consider is how does it compare to tools for speeding up numerical Python such as Numba and JAX. I've considered using Julia for years (and did use it for one project), but Numba / JAX have always been good enough for my purposes.

@SethKurk .I got the @NASAWebb cookie cutter files from @petroffm! He wrote an article and makes the files available for download here! They work great! https://t.co/zJhLnBfstf

To get into the holiday spirit and in anticipation of the long-awaited launch of @NASAWebb, I baked some 1:66 scale gingerbread cookies in the shape of #JWST's primary mirror. https://t.co/JbfG9jsD0R @PhysicsCakes

@leonard_ritter The output of `projectionRawInvert` is in a side-by-side arrangement, like d3.geoGringorten (https://t.co/ZvHgCNPzXP), to match existing d3-geo projections, which use a separate step for the quincuncial arrangement (https://t.co/vzEScZ3Oib).

[Matthew Petroff @petroffm]

Not getting out much these past few months, I came up with a new square equal-area map projection as a side project. It has closed-form forward and inverse solutions, has relatively low angular distortion, and has only tiny cusps. https://t.co/yPnIjVmh6E 1/2

@leonard_ritter The JavaScript implementation should be easier to follow. Vectorizing the code to work with JAX for auto-diff support unfortunately made it a bit of a mess.
