Curate Custom Content with mediastack

6.10.2020
I used to have a personal aggregator of sites I enjoyed but maintaining it was a nightmare. I needed to grab each site’s RSS feed, categorize their contents, deal with errors and individual rate limits, etc. I had to tear the whole project down because it was a nightmare to manage. Fast...

How to Detect When a Sticky Element Gets Pinned

5.10.2020
The need for position: sticky was around for years before it was implemented natively, and I can boast that I implemented it with JavaScript and scroll events for ages. Eventually we got position: sticky, and it works well from a visual perspective, but I wondered how can we determine when...

Shoelace 2.0: A Forward-thinking Library of Web Components

Vital Web Performance

21.9.2020

Remove the Search Input Clear(x) Icon

21.9.2020

Logical Assignment Operators

10.9.2020
I love JavaScript, it’s my favorite programming language, but I love dipping into other languages because they offer a new perspective on coding paradigms. There’ve been syntax additions to JavaScript that I’ve seen I found interesting (think ?? in optional chaining) and now...

Prototyp Starshipu opět „vyskočil“ do výšky 150 metrů

4.9.2020
Šestý prototyp kosmické lodi Starship opět „vyskočil“ do výšky 150 metrů. Došlo k tomu včera na testovacím místě SpaceX v texaském Boca Chica. Stejně jako minule šlo o poměrně zajímavou podívanou. Konstrukce z nerezové oceli, připomínající vodárenskou věž, se zvedla z obrovského prachu kouře a
