The Web Weekly newsletter keeps you up to date, teaches you web development tricks and covers all things working in tech.

Happy Sunday, party people! πŸ‘‹

This week I ran another best time (5:04min/km), I was out sailing for a few days, visited my parents, and I finally set up the Twitter account for Tiny Teachers! It was a good week! πŸŽ‰

Tiny Teachers is Tiny Helpers' best friend and lists online courses and interactive learning resources. listing interactive learning resources.

Currently, it has 0 contributors. 😒 What resources and learning courses do you use to learn web development? I'd love to see them on the site!

And with that – this week's Web Weekly includes:

  • CSS contain
  • Holes in Arrays
  • App and site command palettes

... and, as always, GitHub repositories, a new Tiny Helper and some music.

Something that made me smile

Tweet: .ΰ² _ΰ²  { --οΌˆβ•―Β°β–‘Β°οΌ‰β•―: ︡┻━┻; } is valid CSS.

Tab Atkins-Bittner shared this CSS gem, and while it's mainly useless to use Unicode symbols in code, this custom property definition or .πŸ™ˆ {} class selectors spark joy!

Can we have more command palettes, please?

GitHub command palette

GitHub shipped a command palette (cmd/ctrl + k). As a power user, I appreciate keyboard-first functionality, and I wonder if browsers shouldn't provide command palettes to navigate links and buttons natively.

To keep track of apps, sites and libraries that offer this functionality, I set up awesome-command-palette. I'd love to learn about more places that implement cmd/ctrl + k.

How to decide what to work on

Eisenhower matrix

I'm juggling many tasks at work, and it's a real challenge for me. The Eisenhower decision matrix passed my way multiple times lately, and it helps to evaluate the endless TODO list.

The Chrome origin trial overview

Chrome origin trial overview

Chrome is always at the forefront of developing new browser and web features. Not every feature is rolled out immediately, though. Some features are developed as try-outs, so-called origin trials. Developers then can enable them, play around and provide feedback.

This week I learned that there's a handy Origin Trial overview page. If you're curious and want to know what's possibly coming to Chrome (and maybe the web), this page is excellent.

50 Resources And Tools To Turbocharge Your Copywriting Skills

Freya Giles published an extensive list of writing resources on Smashing Magazine. It includes excellent articles and tools if you want to level up your writing.

Read more library code

You should be ready, willing, and able to read the source code of your dependencies

Jerod Santo shared a hot take. He said that if you're installing dependencies, you should be willing to debug them, too.

First, it's a bold statement. Getting into 3rd party code is challenging, intimidating and takes a lot of time. And there's nothing wrong with googling a problem!

What resonates with me is that debugging library code is time well spent. You'll learn so much by understanding how things work and how other developers approach problems.

Don't be scared of your dependencies

There are so many things to consider for a great and secure product

Spear phising with Slackbot for fun and profit.

I admire product folks with a vision and understanding of what needs to be done to create something excellent. There are so many things to consider when thousands of people use your product!

Eric Bailey wrote a fascinating article describing how you can use Slack and pretend to be Slackbot to phish for information. The Slack people obviously didn't consider this suspicious behavior.

Can it be true? Is the dialog element coming?

Safari release notes announcing the dialog element.

The recent Safari Tech Preview release notes included a surprise. The dialog element will be enabled by default. If you check you'll find out that Firefox is planning to ship it eventually, too, and with this change, the browser support is pretty green! 😲

I didn't spend any time on the element yet, because I read about its accessibility issues. If you want to learn more, Scott Ohara has you covered (and he also updated his blog post already).

A better Medium reading experience

Also, Medium websites are heavy! Reading 700 words can easily cost you three hefty Megabytes worth of fonts and JavaScript. And of course, Medium watches and tracks your entire journey. It's not great! is an online service that takes Medium articles and cuts out all the unnecessary stuff (fonts, tracking, JavaScript), and it's delightful. I have used it for a few days now and can't express how enjoyable pure and uncluttered content is.

Enjoy Medium content

CSS contain

I have to admit that I haven't used the CSS contain property yet, but I loved Johan Isaksson's post describing how he fixed the rendering performance of the Google Search Console.

The beauty of mentoring

That’s why I got into mentoring; I wanted to be the person that I wish I’d had. I didn’t want anyone else entering the industry to experience the loneliness and uncertainty that I did.

I loved Jo Franchetti's post on mentorship. Jo explains that helping others is great for the sake of helping and makes you a better developer, too.

Array methods skip holes

Skipped holes in JavaScript Arrays

When people talk about "dense" and "sparse" arrays, I always have to look up the terms' meaning. Dmitri Pavlutin wrote an excellent summary on the topic, and it reminded me of the moment when I learned that array methods skip holes in sparse arrays.

A new Tiny Helper

Huetone color palette generator.

If you're planning to create a new color palette (I am for my site) and want to keep accessible colors in mind (which you should), Huetone is a great app to come up with great colors.

A quote to think about

I found this week's quote from Sir Gustav Nossal in Jo's mentoring post and love it!

Assume zero knowledge and infinite intelligence.

A song that makes you stop coding

Apparat - Dawan (Official)

Sascha Ring, aka Apparat, entered my running playlist this week and the deep electronic sound with typical Apparat lyrics was the perfect exercise companion.
