The 'update' button in the top right corner changes green to yellow to red.

Yes, so open tabs could be stale. But is there any other reason for browser refreshing?

S-T-R-E-T-C-H. Lay down on a carpeted floor and move.

First whatever feels good. Then on my back for side-to-side head rolls, arms over head, legs lifts, sit-ups, bridges. Then side planks, and finally on stomach for push-ups, planks and some yoga positions. Every day is different.

I think the resulting brain/cell oxygenation from rhythmic slow deep breathing is why it works.

As a quasi-coder, after much looking i've settled on this:

Jupyter Notebook - https://jupyter.org/ -- content creation Hugo - https://gohugo.io/ -- website structure and theme Github - https://github.com/ -- backup and version control Netlify - https://netlify.com/ -- host and deployment

Jupyter makes writing easy, and can export to many formats (html, md, rst, latex, ...). There's also a Jupyter Desktop App available, though it doesn't support extensions. https://github.com/jupyterlab/jupyterlab-desktop

Hugo's easy to setup, has many themes, good documentation, with a logical file system.

Github Desktop makes github easier to use. https://desktop.github.com/

Netlify deploys content directly from Github.

I'd join, because some people are more interesting than others. It requires a 'sufficient complexity' to be a person others find interesting. Some people's faces invoke a story in the viewers mind. Other people's overall persona, conversation skills, or dress. Less visually obvious interesting people need to create/produce things externally - painting, drawing, books, blogs, equations, code, videos, ... to demonstrate their capability. Though that doesn't necessarily make anyone an interesting person, it's for others to decide.

But hasn't all this been going on for millennia? The internet has accelerated the process, lowering the barrier to entry to a few keystrokes. It's a messy Darwinian process, ultimately shaped by a combination of meritocracy and social norms. Complicated by the fact that different people find different things interesting.

So, in conclusion, 'interesting peoples' sites exist, such as HN, Medium, Substack, TED, Stack Exchange, even TikTok. Beauty and interestingness is in the eye of the beholder. Like-minded people tend to find each other. To attract interesting people send some content into the ether world. But a site where the gatekeepers is one person or a board, and not a community, is a reflection of the gatekeepers, akin to a gallerist or a curator.

Magenta is a nonspectral color, meaning it doesn't appear in rainbows or prisms refracting white light (all wavelengths). All pinks and purples are also nonspectral.

Only the fully saturated rainbow colors ROYGBIV are spectral colors. Indigo is deep blue. Violet, borderline between visible and UV light, is a single wavelength, but it excites the tail of our eye's Red cones, so appears bluish-purple.

The CIE Chromaticity Diagram https://en.wikipedia.org/wiki/Chromaticity shows it best, where the spectral colors form the curved outside, and the nonspectral colors are the straight 'line of purple' and all interior colors.

It is surprising that green's (~495-565 nm) complementary colors are all on the nonspectral line of purples (draw line from purple's corner endpoint, through the white point, to corresponding green).

The 46.5 billion light-year distance is TODAY's distance to the observable Universe's limit.

The Universe has been expanding in size since it first appeared 13.8 billion years ago. Since the Universe was smaller in the past, light could travel a further distance in the same time interval. For example, when the Universe was half its current size, a photon traveled 2 light-years every year. Light's "total travel distance" is deduced from its observable redshift z .

If the Universe stopped expanding today, it would take 45.6 billion years for Earth's expanding electromagnetic bubble to reach the edge of today's observable Universe, more than triple the Universe's current age.

The a(t)=3.4 (=46.5/13.8) scale multiplier, which accounts for the Universe's expansion, scales as ~ t^{⅔} where t is a time interval parameter since the Big Bang. See Ned Wright's comprehensive cosmology site for more details. <https://www.astro.ucla.edu/~wright/cosmology_faq.html#z>
