I am personally not a huge floral pattern fan in leather tooling, but give me a Celtic knot and I want to tool it. So obviously I bought a book about Celtic knots and am watching the videos about making Celtic knot algorithms… trying to tell myself that it is a v5.0.0 feature, not v0.2.0 feature ;)

Unsurprisingly, I found two other people created patterning tools for leather workers like the one I’m building and they used AI-assisted workflow aka vibe-coding like I and doing for it. Both started this year. Software got even cheaper. What is a differentiator?

Discovered NJ libraries after many ears, visited 3 this morning to grab a few books about leatherwork and patterns. The information system and easy of use being in and out once you grab what you were looking for is so much better that any commerce establishments that it’s not even funny.

I'm looking to line up my next job! If you need a frontend platform girlie, let me know! I particularly like making complex web apps faster! Could an app you work on, use, or know of benefit from that? LinkedIn: www.linkedin.com/in/zeigenvec... LeadDev Talk: www.youtube.com/watch?v=f-B2... ✨

JOIN US NEXT SATURDAY — @atproto.nyc summer picnic! an atmospheric summer celebration at brooklyn's best park with (we hope) sun & fun bring friends, families, food, drinks, games let's welcome more ppl to the atmosphere!

Draw Leather is just over a month in development and you can see how it grows with GitTerra map here: sergeychernyshev.github.io/drawleather/

nice bit of good news heading into the weekend! this honor ofc testament not to my application writing skills (passable) but to all the great folks publishing with leaflet & wider open social ecosystem! excited for atmospheric publishing & ways we can help give ppl great tools/experiences here :)

Been contemplating about open source and AI recently - the mechanics are shifting with both low comprehension of code and cost/benefit shift causing a change in incentives. So the free part is getting less value. On the other hand more docs, easy code analysis, might be what open was all about.

As a result I just remapped all the coordinates and adjusted the stroke thicknesses and it all seems to work. So +1 for the leather design tool export I am making. I imagine there will be many other tweaks that will be needed for laser users and other digital workflow users.

I believe I figured out an SVG issue with Cricut Design Studio imports that always resize your project - the reason is that they don’t follow the spec and don’t map dimensions through the viewBox and interpret coordinates directly which means the scale doesn’t match and they use heuristics to resize

Just learned that my WeMo switches didn’t just disconnect temporarily. Belkin just shut down the services needed to operate them. Why did I buy into technology that doesn’t work independently? And why is it legal?

Reading up on atproto and itching to resurrect github.com/sergeycherny... - looks like all the technologies have changed since 2008 when I made it, but the spirit of decentralized data lives on.

It was indeed - brought fond memories of Semantic Web community I was heavily involved with right before I went all in on web performance.

Most software goes with standard valid SVG which prescribes this mapping and that’s why import is always borked and users are forced to resize imported geometry manually in Cricut Studio. My Draw Leather tool now keeps that in mind and preps the files so they can be imported without resizing!

Turns out Cricut SVG import just doesn’t re-map from viewBox coordinates to the document dimensions and wants all shapes to use numbers in dimension scale.

Not sure if this meme was already circulating

Obviously in my way home I’m trying to figure out how to use it for Federated Planets game and if it is a good fit.

Hire Jenna, she speeds up your slow frontend apps!

Got my name tag printed as a physical “reply” to this message.

here at @atproto.nyc - June 2026 [h28v234c] #atprotonyc

Our next meetup - "React Performance in the Age of AI" with @zeigenvector.bsky.social on June 18 at 6:00PM! RSVP: nywebperf.com/e/314758263/... #webperformance #nyc #meetup

I’m going to join for the first time - excited about the new federated platform and want to learn more. Maybe it’ll work with the Federated Planets project (if/when I get back to it)

Just attended a lovely talk where a product went from 6.6 seconds to 0.8 seconds for first contentful paint by ditching MUI and CSS-in-JS and using vanilla CSS with in-house components instead. #webexpo

What do I do with all the fucking “genius” product ideas that come to me in fucking middle of the night and wake me up so now I can’t sleep and am better off going to vibe code all that shit?! Or at least ticket it up into the infinite backlog of doom! And that’s just for one fucking side project!

@jennschiffer.com @jbrew.bsky.social there might be a fundamental need for an i18n version of the Robot Karaoke. I have fond memories of pre-internet. Soviet days where when whole USSR would sing English songs with Russian words. Like “Варвара жарит кур".

Where does coder ends and engineer starts? That’s the question. And maybe it’s not only and engineer who starts there, but an artist, a product manager, or an analyst or an entrepreneur. We are not a small cog in a big machine and should not be limited to one job.

I was contemplating my feelings about AI-assisted software engineering and had a thought - “coding is being replaced by AI, engineering is not”. If you’re an engineer and not a coder, you don’t have anything to worry about. If you’re an engineer you might even enjoy it because coding is boring.

Hard to fake. An expert who's been doing web performance for a decade, switching tools and explaining exactly why. That's the kind of proof that actually means something.

Ticket acquired. Can’t wait to see you all later this year! Go get yours!

People say AI sucks at web dev, but why does it suck and what can we do about it? See @philipwalton.com explain why that is and how Modern Web Guidance can help youtu.be/bo3i0FzDUYo

If you want to learn all about web components from a human then check this out: Web Components Demystified online course is $10 this week (it'll go back to the usual $25 deal after that). It's 8 hours of video lessons, or 4 if you listen at 2x, which wouldn't offend me at all. Use the code Just10.

Customizable select coming to Firefox... Soon it'll hopefully be Baseline Newly available. The real question is: how did we put up with old, boring, <selects> for SOOOO long with adding lots and lots of third-party code as the only viable alternative!?

🤯 TIL you can "crop" SVGs using fragment URLs. <img src="diagram.svg#svgView(viewBox(680,130,260,160))" />

A well-written bug report is worth so much more than a drive-by PR with a "solution". Showing us maintainers how to reproduce it is often the real work and improves debugging your skills!

💥 Game changer for Web Development announced at GoogleIO- Modern Web Guidance! It’s expert-vetted skills for web development based on best practices of latest specs and APIs. It ensures your agent/coding harness doesn’t default to older and out of date patterns to build sites.

I was looking forward to trying this out as AIs innate proclivity for React and Tailwind is a disturbing “common practice” as opposed to modern web platforms features that are “best practices”. Tell your AI to do better than the lowest common denominator.

We've been COOKING Modern Web Guidance is a skill pack that helps your coding agent write better, faster, more accessible and secure code Get it at goo.gle/mwg We'd love to know what you think!

Tonight at 6:00PM @ Cloudflare: "Introduction to UX Speed" with @sergeyche.dev. See you there! nywebperf.com/e/314297607/... #webperformance #nyc

on Memorial Day aka May 25th, @jbrew.bsky.social and i will be back at @wonderville.nyc with ~robot karaoke~. 🌭👾🍻🎶 sing foia‘d roblox complaints and other text collections to the tune of your go-to karaoke songs while playing indie arcade games, chomping on gourmet hot dogs and sipping libations!

Demoed tumblecu.be (both, iOS native and android/web) version of the game at the NJ Game Developers meetups today. God some good ideas and feedback!

Company (not my employer at any point) will not be named but I somehow became a member of their Microsoft Azure directory by being emailed to at my gmail account. I hope I didn’t get their super admin permissions with it. But it looks like it fucked up a few VSCode publishing scopes for me.

Saw this game today and was quite immersed into it - very cool story-no-story interaction progression experience. Highly recommend to check it out.

Vibe-coding hard problems feels much worse because you feel like bigger and bigger idiot because you are not learning as you do it.

Last chance to sign up for NY UX Speed & Web Performance meetup on Tuesday, May 19 at 6:00PM at @cloudflare.social offices at 1 WTC: "Introduction to UX Speed" with our own @sergeyche.dev RSVP: nywebperf.com/e/314297607/... ⚠️ Registration closes tomorrow May 15

I’ve been working with a client who runs a lot of social media and ad campaigns, so we’ve been deploying the experimental `No-Vary-Search HTTP` header. It’s amazing to see it actually working! Read all about it here: csswizardry.com/2026/05/bett...

Heard the ad on radio at Dunkin about a Maurice fraud narrated by AI which felt like scam. Something is wrong here…

We just sent out a TEST MAIL to our mailing list. Last year quite a few people didn't see the announcement mail and missed the early bird ticket sale. So this year we run a test first. If you're subscribed to our mailing list, please make sure you got the test mail. Or perfnow.nl/subscribe

First version of the ProjectorOS is vibed together over the weekend. github.com/ProjectorOS/... Calibration, aurco markers and hand gestures to help when markets are occluded by said hands. Python & OpenCV server with SVG + Canvas rendering using Chromium. (video is without hand tracking).

I wrote "Your Voice" in 2016 to encourage people new to speaking & writing to be yourself, to find what's authentic for you and make sure you let that shine through in what you create. Seeing so many social posts and blog posts clearly written by AI—it feels more important today than 10 years ago.
