Publishing Permanent Photo Signatures with Blockchains

I really don’t like copyright notices and logos on images. I wanted a way to digitally (cryptographically) sign my photos before publishing them, so I came up with my own method. I also want my signatures to be public and impossible to corrupt, modify, or delete. How is this possible? "Groan," you say, "don't say with a blockchain". Yes, I am using blockchains (oh no!).

Moon Photo Stacking

A few weeks ago I was out looking for birds to photograph with my Nikon P950. I saw the crescent moon overhead and took a few handheld shots of it. I thought I might play with some astrophotogray stacking software, so I took a few seconds of 1080p video too.

Fundamentally Broken US Government

Vote counting for the 2020 election begins in a few days. But this article isn't about that. There's little use in spending time and energy in constant partisan fighting when our government seems incapable of addressing any of the issues we face in the first place. When you have a leaky roof and you see a storm on the horizon, you don’t fill the house with more and more buckets to deal with the water that will be coming in. You fix the roof.

Setting aside all of the partisan issues of the day, I believe there are three fundamental, structural, non-partisan problems with the Constitution. These core problems are ultimately responsible for our governmental dysfunction and inability to make progress solving the real problems we face. Fixing the core problems should be the priority of reformers — not focusing on issues stemming from them, nor even on other areas our Constitution could be amended.

screensave.js

I am gradually going through my pile of old programming projects and I figure some of them are worth publishing on my blog. One of them I worked on a few years ago, for my harvey.dog site, involved playing with the JavaScript canvas.

Apple Notes Shapes

The Notes app on iPadOS is great for sketching out ideas with my finger. I can switch colors and infinitely erase and move things around much easier than with paper and pen. This concept is straightforward and is featured prominently in the marketing campaigns for the Apple Pencil and iPadOS 14.

I've found that certain shapes are "auto-perfected" by the app if you leave your finger touching the screen for a split second after finishing drawing the shape — a circle or line, for example. This is really nice for making tidy notes and drawings. But what all shapes work with this feature?
