Looking forward to @folkcomputer.bsky.social open house tonight. Ready to be amazed and immerse into physical computing practice and ask a million questions of existing practitioners.

Yeah, one of my personal projects (drawleather.com) has seen 8 “competitors” emerge in 3-4 months with only 1 existing before I myself started earlier this year. Now I doubt my own work as I am vibe-coding the hell out of it too. And yes, trust and certainty about code we all “write” changes.

I feel that it just gave more fuel to this idea extravaganza and more ideas that never hit the public are now done, but ultimately it’s the same as we always had, just with more drafts hitting the public eye.

v0.0.191 of Modern Web Guidance is out and it's a big one! *16* new guides covering: web components by @castastrophe.bsky.social Cross-Origin Storage by @tomayac.com security by @rowan.fyi UI and PWA by @jamessw.com and @sturobson.com Wasm by @sbc100.bsky.social github.com/GoogleChrome...

accessible-web-components: Make custom elements accessible by default, setting roles and ARIA state via the ElementInternals ARIA mixin, managing focus with delegatesFocus, and keeping ARIA relationships within a single shadow root.
custom-elements: Define, register, and manage the lifecycle of autonomous custom elements, covering constructor rules, lifecycle callbacks, upgrade timing, attribute/property reflection, and naming conventions.
form-associated-custom-elements: Make a custom control participate natively in forms with formAssociated and ElementInternals, submitting its own value, integrating with constraint validation, and reacting to reset, disable, and state-restore.
prerendering-custom-elements: Server-render a custom element, then hydrate it in place without re-rendering or a flash of unstyled content.
shadow-dom: Encapsulate a component's DOM and styles with Shadow DOM, construct the tree efficiently with HTML templates, and project consumer content with slots.
styling-web-components: Style across the shadow boundary with :host selectors, inherited and custom properties for theming, ::slotted and ::part, and cascade layers and container queries inside components.
web-components: Orientation and cross-cutting principles for authoring and using Web Components, covering Custom Elements, Shadow DOM, templates and slots, Declarative Shadow DOM, styling across the shadow boundary, Form-Associated Custom Elements, and accessibility requirements. Use this guide when building reusable UI components, design systems, or server-rendered custom elements.
avoid-redundant-large-asset-downloads: Avoid re-downloading and re-storing large shared assets, such as AI models, Wasm modules, or fully-bundled JavaScript libraries, that a visitor's browser may already hold from an unrelated site.
load-shared-resources-declaratively: Serve popular, unmodified scripts, stylesheets, and JavaScript modules from a shared cross-origin cache using markup or import syntax alone, witho…

New Guides
migrate-web-app-origin: Transfer an installed web app to a new origin while preserving user configuration and OS-level shortcuts.
local-network-access: Access resources on a user's local network or loopback interface from a public web application.
trusted-types: Help prevent DOM-based XSS attacks by ensuring all untrusted content is sanitized before being inserted into the page.
responsive-table: Build a data table that presents tabular data with proper header semantics, and remains readable and navigable on small screens and with assistive technologies.
spatial-navigation: Implement accessible spatial navigation using arrow keys that works correctly in different layout modes (grid etc)
cpp-on-the-web: Compile C/C++ to WebAssembly using Emscripten

Updated the animated-select-picker guide to advise using standard value attributes on <option> elements to ensure standard form submission behavior.
Updated the branded-select-styling guide to emphasize retaining standard value attributes on <option> elements to preserve default form submission behaviors.
Updated the custom-select-picker-layouts guide with guidance on using :open::picker(select) selectors, customizing the ::checkmark pseudo-element, wrapping <selectedcontent> in a <button>, and managing keyboard navigation and accessibility constraints for grid layouts.
Updated the rich-media-picker guide to clarify that standard value attributes should be maintained on <option> elements to preserve form submission functionality.
Updated the out-of-order-html-streaming guide to document the full suite of static and streaming DOM insertion methods, detailing built-in sanitizer behaviors, WritableStream integration, and processing instruction marker practices.
Updated the sanitize-untrusted-html guide to detail node manipulation patterns using Document.parseHTML() to avoid mutation XSS, explain child preservation rules via replaceWithChildrenElements, and provide aligned DOMPurify fallback configurations.
Updated…

Removed the prevent-text-wrapping guide.

HTML processing instructions: Added Chrome 150 and Edge 150 support in out-of-order-html-streaming.

A four-column table titled "Benchmark Evaluations" comparing unguided versus guided pass rates across 132 tasks and 1,124 assertions.

Row 1: codex_cli (gpt-5.6-sol) achieved a 59% unguided pass rate and an 81% guided pass rate, an uplift of +22 percentage points.

Row 2: claude_code (claude-sonnet-5) achieved a 54% unguided pass rate and an 87% guided pass rate, an uplift of +33 percentage points.

Row 3: antigravity (gemini-3.8-flash-medium) achieved a 65% unguided pass rate and a 91% guided pass rate, an uplift of +26 percentage points.

Just watched the video by @kevinpowell.co about AI impact on our jobs: www.youtube.com/watch?v=1aW7... I feel like many of us might be having "AI burnout" - a new type of burnout that we in software industry didn't see before. The analogy of moving from hand-crafted to conveyor belts seems right.

The next question is - will there be a multi-account app that lets you do your split personality / corporate brand posting? Currently picking the identity in @bsky.app works well, but can be improved upon for those who‘s job it is to maintain many accounts.

When working noon-8 (e.g. west coast company / east coast home office) is an option would that be your preference? Especially during good weather seasons/weeks when you enjoy it or miss it? I had been shifting my hours sometimes as of late for other reasons but is this a normal thing people do?

It is an interesting feeling to stretch your brain to be able to touch its limits this way. On one hand I hope it is a good mental exercise. On the other I am worried that it can lead to faster exhaustion and burnout. Impostor syndrome also flares up in this mode.

000

Sergey Chernyshev @sergeyche.dev · 02/09/2026

And there are 2 reasons for it: - the obvious pressure and reality of having more projects in flight - but also the fact that you don’t have full grasp on the mental models and need more cognitive effort to comprehend AI agent’s changes and explanations

Sergey Chernyshev @sergeyche.dev · 02/09/2026

Multi-tasking in software space have always been hard as you need to keep mental models of multiple things active in your head at the same time. AI-assisted multi-tasking is even harder.

AI got written texts to be 10x more verbose. My text skimming or fast-reading skill that I develop in my brain over the years only speed reading up by 1.5-2x (this is an estimate). I have no idea how to keep up with this. The only way I can think of is to use AI to summarize what has been written.
