I've streamlined theme development in Ktistec. The theming system uses a hierarchy of CSS custom properties and fallbacks. Theme authors can customize a theme at multiple levels:

Base Colors Only

Define only base colors like --text-primary, --bg-primary, --bg-input, --semantic-primary, etc. Derived colors will auto-generate using color-mix formulas. For example:

:root { --semantic-primary: #ffa500; }

From this one line, theme-appropriate colors like --bg-accent-code, --anchor-color, etc. auto-generate.

Base Colors Plus Derived Colors

Define base colors and derived colors. Derived colors use custom values when defined. Undefined derived colors auto-generate. For example:

:root {
    --text-primary: #333;
    --text-primary-2: #ff0000;  /* red for this specific shade */
}

Given this theme, derived shades like --text-primary-1, --text-primary-3, and --text-primary-4 auto-generate. --text-primary-2 is red.

The simplest possible interesting theme redefines the primary semantic color. The single line above (in Base Colors Only) would result in the following, with button color, link color, disabled, selected, and hover states all derived automatically:

screenshot of the setting page with the primary semantic color defined

These changes will be in the upcoming release. Existing themes will continue to work, as is.

My husband and I were reminiscing about music we listened to as teens. We each had a similar experience with a kind older relative (his grandpa, my aunt), who took us to a record store and said, "Why don't you pick out five albums? We'll listen together, so I can know what young people are listening to these days." Like a kid in a candy shop: a teen in a record shop.

What albums would you have chosen as a teenager?

Between diffusion models and LLMs, tech has inflated a trillion dollar bubble around automating activities that have immense social and cultural capital—writing, art, photography—but little actual capital. It’s harmful to education, culture, and society with minimal overall benefit

More and more, generative models are looking like productivity tobacco. Promoted by biased research, it’s addictive, harmful, and the little benefit it has (nicotine is a somewhat effective ADHD drug, for example) cannot outweigh the fact that it’s hurting us all, directly and indirectly.

This shit is already turning out to be one of the most harmful tech innovations of the 21st century. It needs to be regulated at least as much as tobacco, if not banned outright from most economic spheres

Chernobyl Fungus Appears to Have Evolved an Incredible Ability
sciencealert.com/chernobyl-fun
That fungus is called Cladosporium sphaerospermum, and some scientists think its dark pigment – melanin – may allow it to harness ionizing radiation through a process similar to the way plants harness light for photosynthesis. This proposed mechanism is even referred to as radiosynthesis.

Chernobyl Fungus Appears to Have Evolved an Incredible Ability

The Chernobyl exclusion zone may be off-limits to humans, but ever since the Unit Four reactor at the Chernobyl Nuclear Power Plant exploded nearly 40 years ago, other forms of life have not only moved in but survived, adapted, and appeared to thrive.

Hey look, a dog!
Now that I have your attention….

Remember that genocide we were all protesting and acting on? It’s still ongoing. There’s still barely any aid entering Gaza. There is still bombing and killing with entire families being wiped out. There are still no medical supplies. People are living in freezing cold tents.

Your $10 or more helps provide food and pay for housing, including for a new mom and her baby.

Saw two of these wee guys on the pavement. The one that was not knocked over said something like "you have been detected and are being observed on cctv, please leave the area".

Seems quite strange to ask folk to leave a public pavement? Maybe I should have tried talking to it?
