Hey there ๐Ÿ‘‹

This week I made some progress on a feature which took me way longer than expected to build as I ended up basically rewriting the whole thing for at least three times. But I learned a ton in the progress, so I take it as a win.

Apart from that, it was kind of a short week. I got my booster shot yesterday and reserved today for sleepingand recovering without any important work or calls. But fortunately, it didn’t hit me as hard as the second dose, and I’m feeling much better already, so I might as well get some work done this afternoon.

๐Ÿ›ค Git Rebase

I linked to an article before about the benefits of git rebase vs git merge and started using it myself, which I can highly recommend. This article covers everything you need to know about the basics, with examples to do it from the command line and also some tips on how to configure git.

๐ŸŽจ Relative Colors in CSS

Jim Nielsen shows an experimental feature which allows to use relative color manipulations directly in CSS. It’s currently only supported in Safary Technology Preview 122 behind a flag, but it would be awesome to have this available in more browsers in the future and to have a replacement for SCSS’s lighten() and darken() functions.

Hey there

This week, we got our first small-ish client-project of the year almost finished, made some progress on new blogposts for picu as well as our own company blog.

Apart from that, I read through most of “Complete Guide to Absolutely Everything”, a brilliant book by Hannah Fry and Adam Rutherford, and I love it so far.

Here’s some of the things I was reading this week.

๐Ÿ”ฅ Writing Better CSS

Modern CSS is getting better and better. Alexandr does a great job in explaining some of the cool new features we have at our disposal. Actually, he managed to untangle some of the knots I still had in understanding things like the :is & :where selectors and especially clamp(). If you work with CSS, you should read this post.

๐ŸŽ› CSS Variables in inline styles

When I started using CSS Custom Properties much more, it always bugged me that you have to put them inline, for example if you want to pass a variable from PHP to CSS. Matthias explains why this is much better (not only in terms of accessibility) than direct inline styles would be and has some good examples to illustrate this.

๐Ÿ“ You can use the browsers’ aspect ratio in a media query

Did you know you can use aspect-ratio in a media query ( @media (min-aspect-ratio: 16/9) { ... } ) to react to the proportions of your browser window? I didn’t, but I could imagine a few occasions were this would have come in handy.

๐ŸŒ A not so gentle intro to web3

Another take on the whole web3 discussion. Koos’ opionion is fairly negative, but I think he also backs up his opinions with valid criticism. Apart from the ecological problems, the countless get-rich-quick pyramid schemes and grifters involved, I see one of the core questions blockchain/web3 needs to address is “does it actually solve a real problem, which a database wouldn’t”. And this is not as clear as it seems. For example: if blockchains should solve (or rather remove altogether) “trust” in a digital age but we still need to trust someone, namely the one who’s putting something onto the blockchain, then what’s the benefit of it all? Or, how Benedict Evans put it so eloquently: “The blockchain can’t lie, but you can lie to the blockchain”. Well said.

Koos Looijesteijn โ€“ A not so gentle intro to web3

๐Ÿง Does web3 make the web more centralized?

And yet another one, which focuses on the centralization / decentralization aspects of web3. Wesley argues that the web actually is and always was decentralized and that blockchains like Ethereum even make the web3 more centralized. I’d love to see projects that truly leverage blockchain technology to succeed, but it’s hard to argue about some of the technical aspects they mention in the article.

๐Ÿฆ How Florian uses twitter

Florian wrote down how he uses twitter, and โ€“ even though we have been working together closely for about seven years now โ€“ it still amazes me how completely different we manage things like email or in this case our twitter accounts. While he’s minimalistic and organized, I’m completely chaotic. Maybe that’s why we work together quite well. He’s so damn organized he even “cleares” his timeline on twitter, how crazy is that? Right? I try to get my mails down to mailbox zero, at least from time to time. I read books from cover to cover, if they are any good. But twitter really is just this neverending waterfall of tweets, and if I miss some, the good ones will pop up from retweets of others anyway. And if not, I don’t really care. Always interesting to see how different other people use things.

Hey there and Happy New Year! ๐Ÿ‘‹

Hope you had a wonderful start into what hopefully be the year that brings us somewhat back to normality after *all of this* (waves hands at the pandemic). We had a few days off in the mountains with family and friends, where the picture above is from. I really enjoy the end-of-year days as it’s usually the only time of the year where I am truly logging off. Also, it was great to see family face-to-face for christmas eve, some of which we didn’t see for a full two years.

On a more personal note: We finally got engaged, which โ€“ after 15+ years and two kids โ€“ you could say was about damn time!

๐Ÿ‘ฉโ€๐Ÿ’ป On the “femininity” of CSS

An interesting take on why some developers still think that CSS is not a programming language. Short answer, btw: it is. But Elaina makes a point in this post, why CSS โ€“ for some โ€“ is not seen as a “real” programming language because it’s just there to “make things pretty”, and therefore too feminine. I agree with the overall sentiment and especially liked that she mentions that programming is in fact a most feminine profession, men just pushed the women out after they pioneered in it.

๐Ÿคฅ Marketers are addicted to bad data

Jacques Corby-Tuech has some thoughts about the bad data marketers are addicted to. I’m more than happy not to be in a marketing role where I have to “prove” my worth in such biased numbers. And even when I had a job in marketing, I had a really great boss who recognized that a lot of marketing is experimentation and gut feeling instead of a hard science, and never forced me to work with magic numbers. I’m completely on board with Jacques’ thoughts, to me this feels like a whole industry cheating and lying to themselves in a perpetual game of “look we did this”. It’s especially funny if you compare it (for example) to facebook’s trial before congress, when they had to split the opposite messages between “we are not capable of changing human behaviour” while selling exactly that to their customers. It’s just a very ridiculous business model.

๐ŸŒ Gary Pendergast on WordPress and web3

A few weeks ago I started writing a draft for a post called something like “I don’t have an opinion about NFTs/web3” in which i tried to make sense of what I understand about this topic, and what not. In it, I concluded that much of what I know about crypto/nft/webn3 is that it is highly polarizing and almost all the voices you hear are either overly enthusiastic or hate it to the core. Just as I was thinking about editing this post again, I stumbled upon this article by Gary Pendergast, which was one of the first articles I’ve read on the topic with a more nuanced opinion. I still haven’t formed an opinion, and maybe I don’t have to, but if you see more articles like these, please send them over.

๐Ÿ’ธ The Case Against Crypto

Another one on the topic of crypto & NFTs, this time by Martin O’Leary, where he argues strongly against using crypto. While he’s clearly taking a stance against crypto, he’s making some very valid points and puts a lot of the (negative) thoughts I had about crypto into words, much better than I could.

Barry Pollard (one of the maintainers of the HTTP Archive) is having a look at whether Core Web Vitals have actually made the web faster since their rollout as a ranking signal in Google Search in May 2021.

๐Ÿ›ค git rebase vs merge

I work with git every day of the week, and couldn’t imagine touching any code without it, anymore. But I never really went much further than a pretty basic branching strategy. We usually use branches like main and dev to keep the code that runs on production and staging apart and develop new stuff in feature-branches. But to get changes back into dev, I only ever used git merge. This article explains what git rebase is and in which cases they can make sense. It’s part of a series of posts about git, which covers everything from branching strategies to merge conflicts to more advanced topics.

Last weekend, we had the stomach flu running through our whole family. And just when everyone was somewhat healthy again, our three-year-old daughter caught a pretty nasty eye infection this week to top it off. Thanks to modern medicine and some antibiotics it only lasted a few days and she’s already much better now. But basically, this week was quite a mess and mostly spent recovering and trying to stay ahead of things.

But there are still some positive news: We finally built a first version of the landing page for our “yet-to-be-released-new-project”, which I hopefully can tell more about very soon. Also, we made a little bit of progress on the new email functionality for picu and worked with our content writer on some new blogposts for the picu blog.

Putting together this reading list for the second time now “forced” me to look much more at my own website than I did in the months before, which made me recognize a lot of things I’d like to change or implement. One of those things was a dark mode, which I spent a few evenings experimenting with this week. Still a few quirks, which is why I haven’t released it yet, but it will be ready very soon.

Another idea I was playing and sketching around recently, is building a little “bookshelf” on here, somewhat similar to what David Bauer does. I already take notes and more or less have been tracking the books I read for for a few years, but most of that is on paper or hidden somewhere in a spreadsheet and I would love to get them on here.

Thomas Steiner shows what you can do, or even more important: What browsers can do for us, if we specify color-scheme meta-tags and CSS-properties. With the meta-tag, you can basically tell the browser what color scheme your site uses, before any CSS is loaded and parsed. And the CSS property allows an “element to indicate which color schemes it is comfortable being rendered with”. Sounds abstract at first, but is really powerful if you get the hang of it. โ€“ Improved dark mode default styling with the color-scheme CSS property and the corresponding meta tag

And maybe this act of writing regularly will be the motivation I need to finish some of the posts I accumulated in my drafts over the last couple of months.

This week, we finally settled on a name and bought a domain name for a yet-to-be-launched new project we are working on for a while, and which I’m very excited about!

Updating a local WordPress website from the live server

As many others, for a very long time we used plugins to backup and migrate most WordPress sites from live to local and vice versa. While this works quite well most of the time, you created this “overhead” of having to install and maintain (or uninstall) plugins on client sites. While we researched ways to better integrate and automate our own backup and migration processes, we recently played around with some shell & WP-CLI scripting ourselves. This post by Mark Howells-Mead would have come in handy to get started.
