dotspencer··on Show HN: Dally – A little every day adds up
It's not super clear to me from the site what the app actually does. Is it for habit tracking or journaling? Curious what problem it solves.
dotspencer··on Show HN: Find matching acrylic paints for any HEX color
Yeah so far I've only added brands you can find in craft stores (FolkArt Matte, Apple Barrel, and DecoArt Americana)

Any specific artist brands you'd want to see added?

I can definitely try to make that happen!
dotspencer··on Show HN: Find matching acrylic paints for any HEX color
Yeah the goal was simply to find the closest paints for specific RGB values from a reference image for a pointillism project I was working on.

I wasn’t trying to do the impossible and find the absolute perfect real-world color match. Just something close given the limited palette of acrylic paint brands I could find locally.

I pulled out the RGB values from the solid color areas of the swatch images on the manufacturers' websites for each of the colors.

It's definitely just an approximation of the real-world color, but I figured that if that's the RGB value the manufacturer used, it's probably pretty close.

Then I calculate the euclidean distance between the RGB value from the provided hex and each of the paints, and show the two closest matches from each brand.

dotspencer··on Show HN: Wake Up Time – A calculator that helps you wake up refreshed
I always thought that 8 hours was the best amount of time to sleep but so often I'd still wake up feeling groggy and tired.

Sometimes I'd go to bed at 1AM and wake up around 7AM and feel so refreshed and awake. What's up with that? Turns out, getting 8+ hours of sleep is less important than waking up aligned with your body's sleep cycles, which for most people is every 90 minutes.

I created Wake Up Time so I could quickly see the best wake up times before setting my alarm each night. Because time math is hard... Especially when you're tired.
