This week I got to speak with Chris Nager! I’ve known Chris quite a while. I remember being inspired by his hand-drawn SVG plus symbol and subsequent guide to <path> commands, which inspired my own shortly after I was properly obsessed with SVG. We talk about all sorts of things like accessibility, how far CSS […] The post 362: Chris Nager appeared first on CodePen Blog.

Treemap visualizations are widely used in hierarchical data analysis. If you need to build one but have never done that before, you might think the process is somewhat complicated. Well, not necessarily. I decided to make a step-by-step tutorial explaining how to create awesome interactive treemap charts with ease using JavaScript. And you're gonna love the illustrations! Are we alone in the universe? A question every one of us has asked ourselves at some point. While we are thinking about the odds of the Earth being the only habitable planet in the universe, or not, one of the things we might consider is how big the universe is. Let's look at that with the help of treemaps! In this tutorial, we will be visualizing the scale of the 10 largest galaxies in the known universe using the treemapping technique.

On TheCodingMachine.io there's a tutorial posted by David Negrier covering an interesting idea when handling "falseness" in your PHP application - throwing exceptions rather than returning false. In this case, he introduces the "safe" library to help make this easier. At TheCodingMachine, we are huge fans of PHPStan. PHPStan is an open-source static analysis tool for your PHP code. [...] PHPStan has this notion of "levels" and we strive on each of our projects to reach "level 7" (the maximum level). But PHPStan is constantly improving, and reaching level 7 becomes harder and harder as the tool becomes more strict (this is a good thing!). The post includes an example of this increasing strictness, showing how a more recent check looks at a file_get_contents call and ensures all possible return values are evaluated (it returns false when it errors). They refactor the code example to more correctly check for this, but losing some of the "expressiveness". The tutorial then spends some time talking about the history of PHP and why things return false rather than throw exceptions on error. It covers some of the basics of how the safe library works and a PHPStan extension that can help find places that need to be wrapped by "safe" to throw exceptions when false is returned.

I am often baffled by which articles and videos I publish that becomes popular. The video below for instance for weird reasons seems to be one of my most popular tutorial styles videos ever, which is surprising considering I'm proclaiming to be able to teach you Angular during its 11 minutes, and I barely touch upon Angular in fact. Even weirder is the fact that I've been trying my best to even hide the video, de-emphasising it, by making it "unlisted" now for months, since I personally consider it to be too low quality for wanting to publicly display it on my channel. Still, week after week, month after month, day after day, it seems to be amongst my top 3 most watched videos - So obviously people are sending it back and forth to each other somehow as if it was some sort of hidden secret, or the path to the holy grail or something. What's the lesson learned? I'm not sure to be honest with you, maybe that the best teachers and tutors are "obstacle removers"? Maybe it's not about how much you can teach per minute, but rather about how much obstacles you can remove? Or maybe it's the dark humour of me proclaiming to be able to do something everybody knows is impossible to do, yet still surprisingly (almost) capable of delivering? I don't know to be honest with you. Suggestions ...?
