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. Note This post is a thought [5].

Photoshop for text In the near future, transforming text over an entire document will become as commonplace as filtering images. Steph Ango · stephango.com [1] While the non deterministic nature of llms scare the heck out of me in the sense of just cutting it loose on my writing. letting it go through all of my files and just edit them. I do like the idea of mundane tools like “desaturate”, “Gaussian blur”, evolving out of it for text. I don’t yet see this with the tools we have now, but it will be interesting to see them evolve.

File over app If you want to create digital artifacts that last, they must be files you can control, in formats that are easy to retrieve and read. Use tools that give you... Steph Ango · stephango.com [1] file over app is a fantastic philosophy laid out well and concisely documented very well in this post. The idea is that tools will change, we will want to use different tools, different editors, different computers over time. What’s likely to outlast everything is plain text files that we can interact with a wide variety of tools. Not encrypted in dedicated formats that die with our tools, but in plain text where a computer from 2160 is likey as capable of reading the file as one from 1960 would be.

Today I discovered vim-speeddating [1] by tpope. I’m sure I’ve seen years ago but it did not click for my workflow until today. I often go through pictures from my phone for the past few days and make Posts tagged: shots [2] posts, but I want to date them to about when the image was taken most of the time. This allows me to quickly bump days up and down using c-a and c-x even around the new year. Your browser does not support the video tag. [3] Sound on, listen to those new switches.

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);" > </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.

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.

- I actually like linus’s take here. My parents dropped $4k (~$8k in todays money) on a computer when I was a kid, (which turned into something too $$ to let me touch at that point). I played some educational games that no one else has heard of and I’ve long forgotten along with an early ciivilization game. It was e-waste in 2 years we maybe kept it 5, and it was barely working. Contrast this to my PC now I spent $2k on 3 years ago refurb from 2017, and it has no signs of age from me, does everything I need it to. Ram crisis sucks, the outright reason behind it sucks. But on the bright side you can still get a baller build for less than you could late 90s without inflation. The industry is not there for consumers right now, we had better times, but its still not bad times. Keep the hope alive that good times will come. Note This post is a thought [1].

- 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.

I’ve found Gemini to be very useful lately, especially for finding information within long form content. When writing thought-896 [1], I wanted to use a direct quote from Jeff Dickey, Gemini popped it out very quickly. give me a quote from jeff just before the timestamp I'm at the interviewer asked what makes a good cli and he started talking about stdout/stderr In another case, my wife and I are huge Good Eats fans. Alton Brown taught us how to cook during college and on. We watched every single good eats episode nearly 10 years after they aired. He is back with some updates to those those shows on his Youtube. Gemini gives very good detailed responses with timestamps. Alton Brown had a recent YouTube video for cooking turkey. Can you get the instructions from the video?
