markata-go now has web awesome integration for image compare. It renders a nice web component with a slider to compare two images. It’s done with a class wrapper around the image components. ::: wa-comparison   ::: Without markata-go’s web awesome integration, the above would look like: <script type="module"> import 'https://ka-f.webawesome.com/[email protected]/components/comparison/comparison.js'; </script> <wa-comparison> <img slot="before" src="https://dropper.wayl.one/file/d628ffba-de18-4fff-91a8-700f037df119.webp" alt="Grayscale version of kittens in a basket looking around." /> <img slot="after" src="https://dropper.waylonwalker.com/file/ca30665f-1a15-453e-aab8-221901c7df99.webp" alt="Color version of kittens in a basket looking around." /> </wa-comparison>

More Details Than You Probably Wanted to Know About Recent Updates to My Notes Site Writing about the big beautiful mess that is making things for the world wide web. blog.jim-nielsen.com [1] I love the level of thought that Jim has put into these changes and making sure that urls don’t change. I’ve got a big change in flight to my main site and this is one of the reasons that I’ve been sitting on it so long. I want to make sure urls arent broken, redirects work as they should, and there are no 404’s from existing urls. Currently the new version only exists on a separate deployement https://go.waylonwalker.com/ I also added the ability to “shuffle” between posts. This is mostly for myself. I like to randomly jump through notes I’ve published in the past for reoccurring inspiration Love this idea and have it on my new site already as well, and have really enjoyed using it by pressing it a dozen or so times over the course of a few sessions. It highlights that I have too many posts like stars and thoughts and I should do some weighting to main posts. mine is at https://go.waylonwalker.com/random/ References: [1]: https://blog.jim-nielsen.com/2026/notes-site-updates/

FFmpeg video crop tools.simonwillison.net [1] This was the inspiration for the next update in dropper that became a full clip editor. The one that I’ve long wanted, but forgotten about.

Tiny Tool Town 🏘️ A delightful showcase for free, fun & open source tiny tools. Stupid-delightful software made with love. Tiny Tool Town · tinytooltown.com [1] Learned about this one from the @stipete interview [2] @scotthanselman did on YouTube. This is proof that the internet is alive. It’s such web 1.0 nostalgia to see that people can just build things! Did you know that you can literally just build things and make them exist? You don’t need users, You don’t need a big platform, you can just make something into existance. It seems like something we have forgotten through web 2.0 where everything as become 4 major apps all linking to each other and trying to hoard all of the attention. Scroll through tehre are some really cool apps, probably nothing that has the polish you want, or is going to change your world. What these apps have more than anything you’ve probably used in the recent years, is inspiration. Its xyz, but the way I wanted, or with my little twist. And no one else has to like it but me because I’m the user. References: [1]: https://www.tinytooltown.com/ [2]: https://youtu.be/Wm7tsiJ1nIo?si=_qvZaR5SPWozBjrY

FancyGist fancygist.com [1] I saw this in @cassido’s newsletter this week and had to give it a run. I despise that there is no dark mode and it insists on burning my retinas 😤. But really this is an absolute beate of a web based markdown editor, I love the command mode to press slash and it just pops out in this whimsical animation ready for me to pick what I want.

I keep forgetting about the double gutter problem with nested containers. When you put padding on a parent and the child also has padding, you get twice the spacing you wanted. The Problem # [1] .container { padding: 2rem; } .child { padding: 2rem; } Now your content is 4rem from the edge. Not what I meant at all. The Fix # [2] Either remove padding from the parent or use box-sizing: border-box and plan for it. I usually just drop the parent padding when I realize what I have done.

I feel for Adam, He has built a fantastic product that the world is running with, something we all needed. Something that everyone laughs at turns their nose up “ppft I don’t need that” the first time they see it, but once they try people get it, and a lot of them like it and keep it. But its something that no one really wants to pay for, no matter how big of products get built on it. As we see more and more features coming to css, its not stopping, the work will always be there. I really hope to see something happen to tailwind to keep it afloat. massive growth and revenue down 80% does not help.

Yesterday I wrote about a way to do light mode screen recording [1] to convert to light mode from dark mode with ffmpeg. I was wondering if it could be done entirely on the front end for web applications. Turns out you can. I’m sure there are limited wikis and site builders that don’t allow adding style like this, but it works if you can. <video src="https://dropper.waylonwalker.com/file/1c53dbcb-4b84-4e94-9f04-a42986ab3fa1.mp4?width=800" controls style="filter: invert(1) hue-rotate(180deg) contrast(1.2) saturate(1.1);" > <!--markata-attribution--> </video> 0 deg hue rotate 90 deg hue rotate 180 deg hue rotate 270 deg hue rotate References: [1]: /light-mode-screen-recording/

Convert a video from dark mode to light mode with FFmpeg! Here cassidoo.co [1] Converting video from dark mode to light mode after the fact is a pretty great idea, I’m surprised at how well it does. Its definitely not perfect, but looks really good. References: [1]: https://cassidoo.co/post/ffmpeg-dark-light/

I saw this tip from Cassidoo [1] and had to try it out for myself. I kicked on a screen recording right from where my terminal was, converted it, and it actually looks pretty good. ffmpeg \ -i screenrecording-2026-01-01_10-10-49.mp4 \ -vf "negate,hue=h=180,eq=contrast=1.2:saturation=1.1" \ screenrecording-2026-01-01_10-10-49-light.mp4 Your browser does not support the video tag.

- Yeah there’s some basics, you know things you might expect like using standard error and standard out correctly. One thing I’ll say on that because I think this is commonly misunderstood, standard error is not for errors, it’s for any information that isn’t part of the normal output. So you know often times that’s warnings and errors, but it might just be progress information. You know anytime that you just need to have something go to the user that’s what it’s there for." (6:15 - 6:42) I’ve definitely done this sin in my own tooling before, and it does make things harder to use. I think I still take err/out at face value. I really like the translation Jeff gave here, one is for normal output, i.e. what the user asked for and the other is extra information. So if I wanted to list something and pipe it into something else, stdout only captures the list, thats it. if you have a bunch of information about config warnings, showing environment, are you sure questions, none of that is captured.
