Why you should never use px to set font-size in CSS - Josh Collinsworth blog

Reminder:

em and rem work with the user’s font size; px completely overrides it.

Remix and the Alternate Timeline of Web Development - Jim Nielsen’s Blog

It sounds like Remix takes a sensible approach to progressive enhancement.

Will Serving Real HTML Content Make A Website Faster? Let’s Experiment! - WebPageTest Blog

Spoiler: the answer to the question in the title is a resounding “hell yeah!”

Scott brings receipts.

A fascinating interactive journey through biometrics using your face.

Contra Chrome

I remember when Google Chrome launched. I still have a physical copy of the Scott McCloud explanatory comic knocking around somewhere. Now that comic has been remixed by Leah Elliott to explain how Google Chrome is undermining privacy online.

Laying bare the inner workings of the controversial browser, she creates the ultimate guide to one of the world‘s most widely used surveillance tools.

Can you count on what you measure? | Clearleft

One of my favourite episodes of the Clearleft podcast is on measuring design. This post from Chris is a complements that episode in a sensible and practical style.

What gets measured gets done. You are what you measure. Measurement eliminates argument. If you work in an environment that puts store in these oft-quoted business adages then I urge you to take a moment to challenge your calculations. Let’s review our metrics to ensure they can stand up and be counted.

Test Your Product on a Crappy Laptop - CSS-Tricks

Eric’s response to Chris’s question—“What is one thing people can do to make their website better?”—dovetails nicely with my own answer:

The two real problems here are:

  1. Third-party assets, such as the very analytics and CRM packages you use to determine who is using your product and how they go about it. There’s no real control over the quality or amount of code they add to your site, and setting up the logic to block them loading their own third-party resources is difficult to do.
  2. The people who tell you to add these third-party assets. These people typically aren’t aware of the performance issues caused by the ask, or don’t care because it’s not part of the results they’re judged by.

Jacques Corby-Tuech - Marketers are Addicted to Bad Data

We’ve got click rates, impressions, conversion rates, open rates, ROAS, pageviews, bounces rates, ROI, CPM, CPC, impression share, average position, sessions, channels, landing pages, KPI after never ending KPI.

That’d be fine if all this shit meant something and we knew how to interpret it. But it doesn’t and we don’t.

The reality is much simpler, and therefore much more complex. Most of us don’t understand how data is collected, how these mechanisms work and most importantly where and how they don’t work.

The impoverished language of business | Clearleft

A good post by Andy on “the language of business,” which is most cases turns out to be numbers, numbers, numbers.

While it seems reasonable and fair to expect a modicum of self-awareness of why you’re employed and what business value you drive in the the context of the work you do, sometimes the incessant self-flagellation required to justify and explain this to those who hired you may be a clue to a much deeper and more troubling question at the heart of the organisation you work for.

This pairs nicely with the Clearleft podcast episode on measuring design.

My Challenge to the Web Performance Community — Philip Walton

I’ve noticed a trend in recent years—a trend that I’ve admittedly been part of myself—where performance-minded developers will rebuild a site and then post a screenshot of their Lighthouse score on social media to show off how fast it is.

Mea culpa! I should post my CrUX reports too.

But I’m going to respectfully decline Phil’s advice to use any of the RUM analytics providers he recommends that require me to put another script element on my site. One third-party script is one third-party script too many.

A/A Testing: How I increased conversions 300% by doing absolutely nothing

An oldie but a goodie. If you think you’re getting statistically significant results from A/B testing, you should probably consider doing some A/A testing.

In an A/A test, you run a test using the exact same options for both “variants” in your test.

Remote to who? A working letter

The idea that your job should be the primary source of meaning in your life is an elaborately made trap, propped up across industries, designed to make you a loyal worker who uses the bulk of their intellectual and creative capacity to further their own career.

Travel Remotely

This is a balm!

Choose a city, choose a radio station, choose a mode of transport (I like walking) and enjoy exploring.

Sowing Material’s Future « optional.is/required

Brian and Joschi are considering an interesting approach for their Material conference:

Maybe we should think about a “crop rotation” method for our event? One year in Iceland to help benefit the local community, then the following year move to Germany so it is easier for people to attend, then a third year of rest and change the format to a virtual or remote event. Then repeat on that three year cycle.

The Performance Inequality Gap, 2021 - Infrequently Noted

Developers, particularly in Silicon Valley firms, are definitionally wealthy and enfranchised by world-historical standards. Like upper classes of yore, comfort (“DX”) comes with courtiers happy to declare how important comfort must surely be. It’s bunk, or at least most of it is.

As frontenders, our task is to make services that work well for all, not just the wealthy. If improvements in our tools or our comfort actually deliver improvements in that direction, so much the better. But we must never forget that measurable improvement for users is the yardstick.

Cloudflare’s privacy-first Web Analytics is now available for everyone

Cloudfare’s alternative to Google Analytics is now available—for free—regardless of whether your a Cloudflare customer or not:

Being privacy-first means we don’t track individual users for the purposes of serving analytics. We don’t use any client-side state (like cookies or localStorage) for analytics purposes. Cloudflare also doesn’t track users over time via their IP address, User Agent string, or any other immutable attributes for the purposes of displaying analytics — we consider “fingerprinting” even more intrusive than cookies, because users have no way to opt out.

The Core Web Vitals hype train

Goodhart’s Law applied to Google’s core web vitals:

If developers start to focus solely on Core Web Vitals because it is important for SEO, then some folks will undoubtedly try to game the system.

Personally, my beef with core web vitals is that they introduce even more uneccessary initialisms (see, for example, Harry’s recent post where he uses CWV metrics like LCP, FID, and CLS—alongside TTFB and SI—to look at PLPs, PDPs, and SRPs. I mean, WTF?).

Ambient Reassurance – disambiguity

Ambient reassurance is the experience of small, unplanned moments of interaction with colleagues that provide reassurance that you’re on the right track. They provide encouragement and they help us to maintain self belief in those moments where we are liable to lapse into unproductive self doubt or imposter syndrome.

In hindsight I realise, these moments flowed naturally in an office environment.
