New kilogram standard: how the SI unit of mass is being redefined - Vox

A fascinating look at standards in the real world. In this case, it’s the kilogram, which is shedding its French Revolutionary roots in favour of the Planck constant.

Our messy human measurements have transcended their messy humanness; they have been melded with an eternal truth.

Mention of The Master Of The Kilogram reminded me of The Keeper Of Time.

Great ideas from Addy on where to start with creating a performance budget that can act as a red line you don’t want to cross.

Breaking the Deadlock Between User Experience and Developer Experience · An A List Apart Article

Yes! Yes! Yes!

Our efforts to measure and improve UX are packed with tragically ironic attempts to love our users: we try to find ways to improve our app experiences by bloating them with analytics, split testing, behavioral analysis, and Net Promoter Score popovers. We stack plugins on top of third-party libraries on top of frameworks in the name of making websites “better”—whether it’s something misguided, like adding a carousel to appease some executive’s burning desire to get everything “above the fold,” or something truly intended to help people, like a support chat overlay. Often the net result is a slower page load, a frustrating experience, and/or (usually “and”) a ton of extra code and assets transferred to the browser.

Even tools that are supposed to help measure performance in order to make improvements—like, say, Real User Monitoring—require you to add a script to your web pages …thereby increasing the file size and degrading performance! It’s ironic, in that Alanis Morissette sense of not understanding what irony is.

Stacking tools upon tools may solve our problems, but it’s creating a Jenga tower of problems for our users.

This is a great article about evaluating technology.

Unit deconverter - make your units less useful!

Take a perfectly useful standardised measurement of length, weight, speed or time, and convert to something far less useful (but much more fun).

Net Promoter Score Considered Harmful (and What UX Professionals Can Do About It)

Jared’s spot-on takedown of Net Promoter Scores.

(Andy feels this is like criticising GDP, but GDP measures something that actually happened, whereas NPS, like horoscopes or tea-leaf readings, rely on clairvoyance.)

Why it’s tricky to measure Server-side Rendering performance

A good analysis, but my takeaway was that the article could equally be called Why it’s tricky to measure Client-side Rendering performance. In a nutshell, just looking at metrics can be misleading.

Pre-classified metrics are a good signal for measuring performance. At the end of the day though, they may not properly reflect your site’s performance story. Profile each possibility and give it the eye test.

And it’s always worth bearing this in mind:

The best way to prioritize content by building a static site. Ask yourself if the content needs JavaScript.
