I’m more proud of these 128 kilobytes than anything I’ve built since | by Mike Hall | Jul, 2025 | Medium

I don’t normally link to articles on Medium—I respect you too much—and I do wish this were written on Mike Hall’s own site, but this is just too good not to share.

And don’t dismiss this as a nostalgiac case study from the past:

At no point did the constraints make the product feel compromised. Users on modern devices got a smooth experience and instant feedback, while those on older devices got fast, reliable functionality. Users on feature phones got the same core experience without the bells and whistles.

The constraints forced us to solve problems in ways we wouldn’t have considered otherwise. Without those constraints, we could have just thrown bytes at the problem, but with them every feature had to justify itself. Core functionality had to work everywhere, and without JavaScript crutches proper markup became essential.

This experience changed how I approach design problems. Constraints aren’t a straitjacket, keeping us from doing our best work; they are the foundation that makes innovation possible. When you have to work within severe limitations, you find elegant solutions that scale beyond those limitations.

google webfonts helper

Google Fonts only lets you download .ttf files meaning that if you want to self-host your fonts (and you should), you have to first convert them to .woff2 files.

Luckily this tool has been online for over a decade, doing what Google Fonts should be doing by default.

File over app — Steph Ango

In the fullness of time, the files you create are more important than the tools you use to create them. Apps are ephemeral, but your files have a chance to last.

Accessibility Personas

Personas are often toothless, but these accessibility personas from gov.uk are more practical and useful than most:

Each profile has a different simulation of their persona’s condition and runs the assistive technology they use to help them.

You can use these profiles to experience the web from the perspective of the personas and gain more understanding of accessibility issues.

Write plain text files | Derek Sivers

If you rely on Word, Evernote or Notion, for example, then you can’t work unless you have Word, Evernote, or Notion. You are helpless without them. You are dependent.

But if you only use plain text, you can use any program on any device, forever. It gives great flexibility and peace of mind.

Creating websites with prefers-reduced-data | Polypane Browser for Developers

There’s no browser support yet but that doesn’t mean we can’t start adding prefers-reduced-data to our media queries today. I like the idea of switching between web fonts and system fonts.

AVIF has landed - JakeArchibald.com

There’s a new image format on the browser block and it’s very performant indeed. Jake has all the details you didn’t ask for.

Why 543 KB keep me up at night - Manuel Matuzović

How and when did I get to the point where I would consider a page weight of 4 MB on a large page and 500 KB on a small page normal?

This isn’t just a well-earned rant from Manuel. I mean, it *is that, but it’s also packed with practical performance advice.

JavaScript | 2019 | The Web Almanac by HTTP Archive

It’s time for a look at the state of the web when it comes to JavaScript usage. Here’s the report powered by data from HTTP Archive:

JavaScript is the most costly resource we send to browsers; having to be downloaded, parsed, compiled, and finally executed. Although browsers have significantly decreased the time it takes to parse and compile scripts, download and execution have become the most expensive stages when JavaScript is processed by a web page.

Sending smaller JavaScript bundles to the browser is the best way to reduce download times, and in turn improve page performance. But how much JavaScript do we really use?

When it comes to frameworks and UI libraries, there are some interesting numbers. Given the volume of chatter in the dev world, you’d be forgiven for thinking that React is used on the majority of websites today. The real number? 4.6% of websites. That’s less than the number of websites using CSS custom properties.

This is reminding me of what I wrote about dev perception.

Everything is Amazing, But Nothing is Ours – alexdanco.com

Worlds of scarcity are made out of things. Worlds of abundance are made out of dependencies. That’s the software playbook: find a system made of costly, redundant objects; and rearrange it into a fast, frictionless system made of logical dependencies. The delta in performance is irresistible, and dependencies are a compelling building block: they seem like just a piece of logic, with no cost and no friction. But they absolutely have a cost: the cost is complexity, outsourced agency, and brittleness. The cost of ownership is up front and visible; the cost of access is back-dated and hidden.

Blot – A blogging platform with no interface

This looks like a nice way to get a blog up and running:

Blot turns a folder into a blog. Drag-and-drop ﬁles inside to publish. Images, text ﬁles, Word Documents, Markdown and more become blog posts automatically.

Progressive Font Enrichment: reinventing web font performance | Responsive Web Typography

Jason describes the next big thing in web typography: streaming fonts!

…to enable the ability for only the required part of the font be downloaded on any given page, and for subsequent requests for that font to dynamically ‘patch’ the original download with additional sets of glyphs as required on successive page views—even if they occur on separate sites.

This is my kind of URL nerdery. Remy ponders all the permutations of URLs ending with slashes, ending without slashes, ending with with a file extension…

This’ll be handy the next time I want to send someone a file: drop it in here, and then paste the link into a DM/chat.

Limiting JavaScript? - TimKadlec.com

Following on from that proposal for a browser feature that I linked to yesterday, Tim thinks through all the permutations and possibilities of user agents allowing users to throttle resources:

If a limit does get enforced (it’s important to remember this is still a big if right now), as long as it’s handled with care I can see it being an excellent thing for the web that prioritizes users, while still giving developers the ability to take control of the situation themselves.
