I got an iPhone X with the new gesture interface a while ago. My One Plus 7 Pro updated to Android 10 with a new gesture interface a few months ago. They’re quite similar, though different in some regards, and I think I’ve had enough time to familiarize myself with both and make some observations.

I really dislike writing tests. There’s some amount of discomfort I’d be willing to sustain if I felt it they were beneficial, but I also find they’re rarely worth the bother. Some reasons why. Most of this probably applicable specifically to unit testing, but some other bits to integration testing.

Sometimes there’s a bad implementation of a good idea, which typically results in discussions turning into shouting matches between people who see only the bad implementation and people who see only the good idea. And sometimes seems more like always when it comes to smart devices, or the internet of things, aka ioshit.

Postel’s law, also known as the robustness principle, states that we should all be friends and try to get along. It’s also occasionally harmful. Here’s an example.

A while back somebody posted some “amazing” images which were black and white except for the stripes that were colored. So, not black and white, but the point was to demonstrate that vision is highly perceptual and the brain will interpolate from what’s there. I thought this might be fun to play around with. I guess it kinda works, but I think some of the demo images were selected carefully.

Saving this here so it’s less trouble to find in the future. Ten years later and there’s still no generic means to accomplish this most simple of tasks without device specific junkware except via registry hackery.

Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Enum\HID\*\*\Device` Parameters FlipFlopWheel -EA 0 | ForEach-Object { Set-ItemProperty $_.PSPath FlipFlopWheel 1 }

I’m aware of two occasions on which Knuth advised editing existing code, as opposed to simply using it. One mention is in this interview, advocating for “re-editable” code instead of the fashionable reusable code, although it doesn’t amount to much more than that statement. In Coders at Work he describes a system of working that’s basically patch and diff. He writes a program, the master version that works for him, and ships it out. People receive and it and then modify it with change files so it works for them.

I used to drink coffee for the sake of drinking coffee. In recent years I mostly switched to drinking coffee for the sake of going out and having something to do. Since I no longer go outside and there’s nowhere to go anyway, I have stopped drinking coffee, but since I’ve been spending so much time inside peering into my pantry, I found a bag of coffee from the before times and thought I’d have some fun.

You have a blob of some data which you would like to embed into your C program. Perhaps a splash screen, or a special font, firmware for your scsi card, or whatever. The usual approach which I think most people are familiar with is to run something like xxd -i to generate a source file with a large array of hex constants. Or write your own little script for that purpose.

I was supposed to be spending the past month or so traveling. That didn’t go quite as planned, but I nevertheless spent some time preparing for the trip, and as part of that, set up a Google Pixel Slate to take along. Even though I didn’t actually complete the experiment, most of the effort was validating it could work, and I think it would have been fine.
