2020 Roundup of Web Research


It’s December! Lots of things are published this time of year, like developer advent calendars and organizations reflecting on the past year. We have even our own end-of-year series where we asked folks what they learned in 2020. But we also see lots of research come out around this time....

Retrospective on Fela


I really appreciate a real-world walkthrough of a technology. Not only in what that technology does, but why it was chosen and how it worked for a team. Anybody can read the docs, but what you know after years of real-world usage is far more valuable. Hugo “Kitty” Giraudel: I want to properly...

Converting and Optimizing Images From the Command Line


Images take up to 50% of the total size of an average web page. And if images are not optimized, users end up downloading extra bytes. And if they’re downloading extra bytes, the site not only takes that much more time to load, but users are using more data, both of which can be resolved, at least...

“I Don’t Know”


I’ve learned to be more comfortable not knowing. “I don’t know”, comes easier now. “I don’t know anything about that.” It’s okay. It feels good to say. Whether it’s service workers, Houdini, shadow DOM, web components, HTTP2, CSS grid, “micro-front ends”, AVIF… there are many paths before...

Can Decentralized Finance Ever Be Regulated?


Iwa Salami, Senior Lecturer in Financial Law and Regulation, University of East London. As stock markets around the world struggle through the pandemic, bitcoin (BTC) has seen a steady rise in its price. In December, the cryptocurrency surpassed its all-time high of USD 20,000 and hit USD 24,000...

Change vs. Inertia


Recently, I’ve become more deeply aware of the inherent tension between change and inertia, as it applies to the evolution and use of web technologies. These forces have always been present and opposed to each other, but it seems to me that the side effects of these collisions are impacting...

Optimizing Image Depth


Something I learned (or, I guess, re-learned) this year is how important it is to pay close attention to the bit depth of images. Way back in the day, we used to obsessively choose between 2-, 4-, or 8-bit color depth on our GIFs, because when lots of users were using dialup modems to surf the...

What Makes CSS Hard To Master


Tim Severien: I feel we, the community, have to acknowledge that CSS is easy to get started with and hard to master. Let’s reflect on the language and find out what makes it hard. Tim’s reasons CSS is hard (in my own words): You can look at a matching Ruleset, and still not have the whole...

What’s Old is New


This year, I learned a lot about how “old” tricks can solve a lot of modern problems if you use the right tools. Following the growth of Jamstack-style development has been both a learning experience, while also a nostalgic one. It’s been amazing to see how you can power plain...

New Law in Germany Embraces All-Electronic and Blockchain Crypto Securities


The German government has passed new legislation to introduce all-electronic securities as part of the country’s wider blockchain strategy. According to the country’s finance ministry, the new law relaxes rules forcing issuers and holders of securities to document transactions with...

I learned to love the Same-Origin Policy


I spent a good chunk of my work life this year trying (in collaboration with the amazing Noam Rosenthal) to standardize a new web platform feature: a way to modify the intrinsic size and resolution of images. And hey! We did it! But boy, was it ever a learning experience. This wasn’t my first...

25 Years of JavaScript & 25 Free Courses


(This is a sponsored post.) Pluralsight is giving away 25 courses on JavaScript for free to celebrate JavaScript’s 25th birthday. It’s no cheapie, either. The courses range from getting your hands dirty with JavaScript for the first time, to full-on reactive development....

21M Bitcoin and the Promise of Scarcity


In Bitcoin, the promise of a limited supply is great. This was one of the biggest things that initially appealed to me when I heard about Bitcoin. “No more than twenty one million bitcoins will ever exist!” But can this promise be kept in the long run? Has the Promise Already Been...
