A rather geeky/technical weblog, est. 2001, by Bramus
Part of a PHP project I’m working contains a list of sites/buildings. For each site/building we monitor some data, for example its energy usage. We decided that we wanted to generate a daily/weekly/monthly reports of the data, by aggregating the datapoints. As our sites/buildings are spread across the globe – and thus timezones – we …
If you’re a regular reader of bram.us you might have noticed that I haven’t posted anything here during the past month. In short: I’ve been busy with many (personal) things that needed my attention. Here’s a few of the things that kept me from blogging … Public Speaking With COVID-19 many conferences have switched to …
Back in November I was invited to speak at Full Stack Europe 2019. At the conference I was scheduled to do a pre-conference workshop on React and a lightning talk named “JavaScript Yellow” — a talk I first presented at Frontend United back in 2018. Last week the video got released: References: javascript-yellow Robustness and …
Ever since September 2019 I had this issue with my MacBook Pro where kernel_task would sometimes spike up to > 1000% (!) CPU load and drain my battery – even while connected to a charger. Second time this month kernel_task (with pid 0) decided to go nuts and drain my battery until my macbook shut …

In Playing With (Fake) Container Queries Chris used the <resize-asaurus> web component to make the elements resizable. Curious to see how that worked I dug into its source. As I was expecting a truckload of JavaScript to make it work, I was very surprised to see that it basically revolved around using just one single …

Update 2020.07.21: This proposal made it into Stage-4 and will officially be part of ES2021 🥳 A new ECMAScript Proposal that I’m looking forward to is Logical Assignment Operators. In short it combines Logical Operators (||, &&, and ??) with Assignment Expressions (=). // "Or Or Equals" (or, the Mallet operator) a ||= b; // …

100vh in Safari on iOS
Update 2021.07.08: There are new viewport units on the way that will finally solve this issue. 100dvh is the one you’re looking for. When working with Viewport Units there’s this longstanding and extremely annoying bug in Safari on iOS where it does not play nice with the vh unit. Setting a container to 100vh for …
UPDATE 2020.10.22: Masonry Layout founds its home in the CSS Grid Module Level 3 Draft Spec! A long requested CSS feature is to be able to create a “Masonry Layout” using pure CSS.
