In addition to missing oklab/oklch, the article is also wrong in claiming web/css supports only srgb; css color() function supports many colorspaces

Author here. The article was published 2 years ago, and when I started working on the tool the spec for OkLCH didn't even come out yet (late Dec 2020). Today I'd choose OkLCH over LCH as it solves a few problems with it.

The problem with being a slave to these Lighthouse scores is the test is only concerned with the one page you are testing. If you assume your visitor will only visit a single page on your site that's fine, but even if they visit a second page, nearly everything it suggests you do will make that second page load slower than if you had developed the page using the traditional methods- external CSS/JS files that apply to your entire site and can be cached.

I use a Lighthouse score for troubleshooting, but at the end of the article there is a chart of the change in Core Web Vitals, which tracks performance of _all_ pages indexed by Google over time.

> "…nearly everything it suggests you do will make that second page load slower…"

This is just not true for _any_ of the suggestions in the article. I guess you can make this argument for breaking down one CSS bundle into four, but their content was picked based on analytics of where people go more often. We make 1 extra request but load much less cruft, and it applies to any page of the website.

I've worked on a number of these projects where clients were chasing Lighthouse scores without any actual measure of effort, reward, or impact.

Google Analytics offers many site speed metrics that are tied to real-world visits and can be correlated with other metrics, behaviors, and conversions on the site itself. These numbers also give you visibility on the entire site and not just a single page that you've run through the Lighthouse tool.

I don't want to discourage people from making the web faster but Lighthouse scores are about as helpful as domain authority and Alexa rank when you can take a detailed look at your users through Google Analytics and get more granular performance analysis from WebPageTest.org (which also provides Lighthouse scores, can be run privately, simulates various devices and locations, and much more).

The Lighthouse score is just a detailed and useful metric for troubleshooting, but not the only one we monitor. I included a chart from our Core Web Vitals in the end, which monitors the performance of all pages indexed by Google and uses actual usage data from a wide sample of users (Chrome User Experience Report).

https://lighthouse-dot-webdotdevsite.appspot.com//lh/html?ur... web.dev says 66 though

efedorenko · 5 years ago

https://developers.google.com/speed/pagespeed/insights/?url=... shows 99-100 every time I load it ¯\_(ツ)_/¯

Our mobile score is lower (86 according to PageSpeed), but I mention that in a blog post.

It looks like the accessibility score went down, too.

efedorenko · 5 years ago

Hi, author here. Accessibility score went from 87 to 96. The second screenshot with a score of 86 was a preliminary result after introducing the fake widget. (Best Practices went from 86 to 100.)

Thank you so much for this article.

I read his book and one of the points he made was you could never "make up" missing sleep.

For example, if you pulled an all nighter, you couldn't make it up the next few days if you slept more. Basically the health effects of missing a day of sleep would affect you for the rest of your life.

That was a quite shocking. Were you able to find any information on whether he was exaggerating this?

efedorenko · 6 years ago

That was one of the things that confused the hell out of me as well.

I remember the library at my university being excellent at getting me in the "flow". It's not so much about "open office vs private office" as it is the expectation in those places.

I'm toying with the idea of recreating a library-like environment that is super quiet and zen-like, but not limited in number of people. Go there for flow-type work. On the flip side, have a cafe-like environment for animated collaborations. Of course, there needs to be a great insulation between the 2, perhaps have them on a different floor.

efedorenko · 11 years ago

There is a point when super quiet environment with other people becomes uncomfortable. We often keep music on quietly even if there are just a couple people in the office.
