I guess we weren’t meant to be

Monday I (41) was playing half court 3v3 at the ymca. We won our game and thus stayed on for the next. Suddenly 2 players joined our team. 5 new players came in to challenge, and I found myself forced into my first full court game since 2003. Today (Thursday), I am still very very sore.

During drafting of this book, I realized there was a problem with the voice of one of the characters. I nailed her voice in 3 but in hindsight wasn’t even close in 1. There’ve been several revisions like that, editing 1 in light of improvements made in 2 and 3. The benefit of taking your time

Read most of draft 1.0.0 of book 3 of my series to the 13 & 11yo last night. Pretty encouraged. They hated the wondrous scene (just short of booing… which they have done before) so need to redo that. But big laughs and tears for the other chapters. Parts I wasn’t feeling they were a LOT. Good stuff

So something that’s kind of interesting about this, as an Indy (600k reg voters) resident is that I’m now gerry-cousins with a bunch of these red counties with 5-20k voters. Yeah they’re trying to dilute our votes but now we have 4 reps who need to court us to build a sizable coalition

🪄Let’s get into some algecadabra 🪄 We can write any two numbers near 100 as (100-A) and (100-B). For example 98 is 100-2 and 97 is 100-3. Multiplying these numbers gives (100-A)(100-B). Let’s multipl... TikTok video by Sums of Anarchy Official

I am reminded of this video also around the ease of multiplying by 100. www.tiktok.com/t/ZP8DxqTJn/

I just discovered the 0s trick in multiplication applies across all baseN (at least that I’ve found) so 100x100 in hex/base16 = 10000.
256x256=65,536 and 65536 in hex is 10000.
3600x6? Thats easy in base 60 (how we measure time): 6:0:0

Just explained to a friend my semantic versioning and branching strategy with my story drafts

I look at Indiana code requiring township trustees to provide insulin to those in need. That part of us is still here.

Node.js 2025: What's new and what's next This talks is a recap of what went on in the Node.js runtime in 2024-2025. Presented at JSConf US 2025

Here are the slides for my Node.js year in review talk: speakerdeck.com/ruyadorno/no...

Went great. Recovering well. Should be out today even

Talking to myself here. Appendix. They’re saying it’s a very routine surgery. Should be fine. And here we go

Choose your own adventure day lololololol

Okay, so a few states away, my kid is getting an emergency surgery (I think appendix) so I’m heading out early this year. It’s been fun #jsconf

“Shift left” is prevention over correction. AI magic wands can’t backfill at the end. By educating the team early in the process, however, you will ship more complete work sooner #jsconf

So even with good prompts, copilot made errors. Great a11y is absent from the majority of training data, so you will need to inspect and test rigorously.

Watch YouTube videos, learn how screen readers are used
#jsconf

Be sure you anticipate the errors and test edge cases (demo where a disabled button was ignored and not announced). Letter of the law is often not good enough. Good news was when sharing feedback with copilot, it had good suggestions
#jsconf

General loop
1. “What are some a11y suggestions?”
2. Test
3. Describe to copilot what you experienced
4. Implement next set of suggestions

The more clear you can be in your prompt, the better results you get. Pro tip there is a “foundational accessibility prompt” that Microsoft has shared
#jsconf

WCAG guidelines are very detailed but come down to
1. Perceivable
2. Operable
3. Understandable
4. Robust
#jsconf

This work is about removing barriers for your users. Requiring two hands example and benefits everyone. Example if you require two hands this is a barrier with a broken arm, a mother holding a child, a person holding a grocery bag. Lots of reasons for barriers and removing helps all

Platformatic/flame wraps it all up for you.
In production, you need a flame graph controller. Platformatic/Intelligent-command-center written to be this controller
#jsconf

Data dog has pprof which solves the inspector overhead.

react-pprof visualizes it it in webgl (fast, a11y, responsive, visual regression testing)
#jsconf

Tradeoffs in methods:
- Complex instructions
- overhead (inspector protocol)
- dtrace (requires root doesn’t work in docker)

It’s React/redux loop time, so the amount of time it takes from the Redux store update to all the components maybe re-rendering!
