Vibe coded a demo of the new navigator.cpuPerformance API in Chromium: rbyers.github.io/cpu-performa.... It's a small thing (returns just 0-4), but for some powerful web apps I think it'll be super useful. Details: github.com/WICG/cpu-per...

CSS Quake (cssquake.com) - no canvas just HTML/CSS using a cool library called PolyCSS (polycss.com). 😀 Playing through the first level brought back a lot of memories. I think I was one of the first to reverse engineer the PAK file format and build an editor days after the game came out.

Given how Chromium and WebKit are always vying for the top spot in Speedometer on MacOS, it's really striking how big the gap is on iOS! And we haven't even really tried to optimize performance for that platform yet! IMHO this is what you should expect to see when there's a lack of competition!

A great analysis! The punch lines: "The trend is clear: for every 100 milliseconds slower a store loads, conversion tends to be about 3.5% lower." "For every 32 milliseconds slower a store responds to interactions, conversion tends to drop by about 1.5%."

I think part of the phenomena here is that it is easy to predict things will fail: most things fail. So, stop energy is much cheaper to produce, because you would be right 99% of the time. Against-everything-for-nothing is a comfortable stance to take, but long term it is the 1% that move forward.

Just bought a new Razer mouse. Rather than install the native app, I had Gemini/Claude write a web app with the Web HID API, using the Linux driver as a reference. Less than 60 min of work laterand I think I'm done: razerweb.rbyers.ca It's a new world... Software on-demand!

Someone in my family asked what they can say to a tech support scammer calling them to confirm they are a scam, not a legitimate company. Thoughts?

It’s fair to say that the V8 javascript engine runs on billions of devices today. And if you apply to this position on my team, you might get to work on it! Talk about impact!

An interesting lightning talk at BlinkOn about a little experiment @rbyers.net did -- 3 minutes to watch and share your thoughts! Very curious to hear them! youtu.be/b_R3o3VASjc?...

I'm excited about FedCM ambient UI. Balancing tough tradeoffs is one of the hardest things we do in Chrome and the only way to do it well is to experiment heavily and collect user feedback.

Another day, another step down the path of our devices prioritizing their manufacturer's interests over the interests of the device owners. mashable.com/article/appl...

Chrome is announcing that they are moving into a two-week release cycle! Exciting bc the web needs to move quickly- resolving bug fixes, feature improvements, etc. It goes along with devops principles of shipping smaller, more frequent releases for stability developer.chrome.com/blog/chrome-...

How will agentic coding tools impact app platform choices? Lovable says: "web apps cost 40-60% less than native development and reach the market 50-70% faster." lovable.dev/guides/nativ...

6 years and 300+ experiments later, I've concluded that sequencing all the viruses going through my house is actually slightly useful, while still wildly impractical of course! lab.rbyers.ca/essays/20260...

Wow, I am constantly impressed by Google Antigravity and Gemini 3.5 pro. I used it to build a whole blog website, including totally custom Tweet archive, in just a few hours of work! Eg. see lab.rbyers.ca/posts/2024. Code at github.com/Rbyers/lab-b....

My talk at @henrihelvetica.bsky.social's SPDY meetup in Toronto is live: www.youtube.com/watch?v=xq2c.... It's pretty rough and unpolished, but I included some fun stories of the history of performance work in Chrome which you likely can't find anywhere else. Slides: docs.google.com/presentation...

That feeling when a family member shares photos like this 🤬😭. I spent much of Sunday formatting and reinstalling Windows, and formulating a credit card transaction dispute.

I hosted a number of visiting global Chrome leads in Waterloo this week. Several had never seen snow quite like we had today, so of course we had to take them tobogganing. Looks like we'll be doing Chrome leads summits in Canada every winter now 😂.

The Chrome Identity and Payments team in Waterloo Canada is hiring several early/mid-career developers. I'm on the lookout for exceptional candidates with a passion for browsers and/or the identity/payments space! www.linkedin.com/posts/rick-b...

Progressive enhancement is really important for enabling the best possible user experiences for everyone!

✨ Exciting proposal alert: the CPU Performance API. This proposal will add `navigator.cpuPerformance`, a value that measures the broad performance capability of the CPU. That way, we can scale up/down our animations to make sure everyone has the best experience possible for their device. 😄

I just almost made a dumb mistake. I've been enjoying Kurzgesagt videos for years (on various devices). After watching their video on AI slop I figured it was time to support them on a recurring basis, so I hit the join button... youtu.be/_zfN9wnPvU0?...

It was fun to be part of this, thanks Henri! I wasn't able to join the livestream for the rest today but really looking forward to listening to it over the next couple days!

Lots of people incorrectly claiming Chrome/Google "tried to kill JPEG XL". Just because an engine chooses not to be the FIRST to ship a new technology does NOT mean they are trying to kill it!

How does one correct Wikipedia when the primary source is wrong and there is no correct primary source? Make one? When I joined Chrome in Waterloo in 2010, we were a relatively new and small team focused on ChromeOS.

One of my jobs on Chrome is quantifying overall product quality signals. This quarter we're taking a hit on crashes entirely due to iOS, which looks to be primarily due to WebKit and iOS bugs. When I try to check on the status of the current major one (bugs.webkit.org/show_bug.cgi...), I get this:

The Web is the platform you are looking for. Pass it on.

Computing some preliminary analysis over the #StateOfHTML pain points data and some …interesting patterns are emerging 🙃

A few years ago I started writing about evolving web standards and @rbyers.net suggested I should cover WPT: the web platform tests project that most people working with the web have a vague idea about that has evolved into an engine of interoperability. since then, I've been tracking people down

Why I 🧡 the web. This #WebGL game where you deliver messages on a tiny planet is amazing. Smooth animation. Peaceful vibes (and i didn't even play, I wondered around). messenger.abeto.co #JavaScript #chillvibe #game

The question isn't "is Tylenol use in pregnancy associated with autism?", its "does treating fever with Tylenol during pregnancy increase or decrease the risk of autism?". europepmc.org/article/MED/...

When I was on an H1-B working in Redmond 20 years ago my immigration lawyers asked me last minute to cancel a trip for legal reasons. My response: "attending family events is more important to me than living in your country".

Yup. We're ready at Google Waterloo, we've got a beautiful new building open! Common north!

You still have time, The State of HTML 2025 survey is live. Browser vendors use this data to prioritize features, fix incompatibilities. Standards bodies use it too. It’s not just a survey, it’s influence. Take 10 minutes. Share what you care about. 👇 stateofhtml.com/en-US

Who is free in the bay area this afternoon and wants to be inspired by computing's past while chatting about the future of the web? Join me at the Computer History Museum around 3-5pm today! [1/7]

How did I go 46 years without experiencing the joy of enterprise-grade network gear at home? Worth every penny...

I think this will be wonderful for the future of the open web: blog.cloudflare.com/introducing-.... As Matthew Prince says, imagine if we could create a system whereby creators and content aggregators could efficiently negotiate a fair price for use of their content.

In tech we are so good at blaming the user for our design flaws! Me: "All 4 of my hotel keys stopped working." Hotel: "Did you keep them near phones? That can demagnetize them, happens all the time." Me: "No it can't! These are NFC cards, not magstripe cards." 😂

🎙️ New Episode of Igalia Chats Unshipping: How (and when) to break web features @bkardell.com and @meyerweb.com chat with Google's @rbyers.net about willingness to change and even unship features www.igalia.com/chats/unship...

DBSC is exciting! I hope it will lead to both meaningful better security and less hassle getting logged out all the time from websites. The convention of mobile apps staying logged in but websites logging out by default makes the web more frustrating!

I'm particularly excited about the emerging support for zero-knowledge proof age attestations. We must move past sharing sensitive PII online just for the purposes of verifying adulthood!

Origin trial: Cross-device Digital Credentials API now in Chrome desktop developer.chrome.com/blog/digital...

Great article! The collaboration in Interop and WPT is really critical for a decent developer experience of the web!

I'm excited about this program! Chromium isn't necessarily easy, but I know there are great engineers out there who would love to get paid for improving it!

Having an AI coding assistant decide to launch a browser and test the bugfix it made is pretty incredible! This is cline.bot

Fascinating study on the lack of effect of news content on Google search usage and ad revenue in Europe. storage.googleapis.com/gweb-uniblog...

If we're going to solve the content trustworthiness problem (and IMHO we MUST in the age of AI), then I'm confident it'll be primarily through ideas like this: www.youtube.com/watch?v=nTaA...

The Radiacode gamma spectrometer is a fun toy! My daughter discovered that this Mosasaur jaw we have is radioactive! It contains Bismuth-214, likely from uranium ore decay. Radiation is about 10x the background level, a bit more than the Am-241 smoke detectors in my house.

Great stuff for web devs in Interop 2025! View transitions, navigation API, core web vitals, anchor positioning, etc! We started the year with a low score (27%) so have a lot of work to do as a browser engine community to get broad interoperability on these important features! wpt.fyi/interop-2025
