Last time I wrote one of these recaps was in 2016. Not sure why I waited three years to write another, and from now on I'll try to do these annually. 2019 was a good year for me, and I want to highlight a couple of things. Blog # I'm really proud of my blog. And judging by the analytics, people are ...

Update, September 2025 # Replaced path.toShapes(true) with SVGLoader.createShapes(path) because toShapes misses some of the SVG-specific logic implemented in the loader. Thanks to forresto who pointed it out. Also updated the demo to use a fresh version of ThreeJS. These days I'm playing with three....

Another Catalina rant, this time about Ruby. As far as I know, on MacOS, it is advisable to leave system Ruby version to the OSFor example users don't have write permission on the system's gems folder. , and install a separate version for development. I had one installed via Homebrew, and never had ...

Yesterday I updated my work laptop to MacOS Catalina.To be able to use AirPods Pro with it :/ Apple made a change and switched the default shell to zsh (instead of bash). From what I have read, the reason is a licensing issue. Bash is not gone and everything will work like it used to. But every time...

I love easter eggs in software. You may have noticed the keyboard image in the background of my blog. This thing on the right side of the screen. Those with a keen eye figured out it highlights keys as you are typing. It has been here for some time now, and on my colleague's request, I'll explain ho...

Short Firefox tip to disable Cmd + MouseWheel zoom. There is a weird interaction with it. Therefore I decided to turn it off completely (I never used it anyway). When I scroll a page using a trackpad and start switching tabs via Cmd + Tab, inertia scrolling would still be active, and the page I swit...

Two years ago I wrote this rant. Firefox had a problem on MacOS on scaled resolutions, resulting in insanely high CPU usage and battery drain. Issue is finally fixed, and I'm happy to say I'm using it again. The fix is expected to land in the stable version in late October 2019, with the release of ...

Please note that I'm not using Jekyll anymore, so this post might be outdated.I'm using Staticman as a comment system on this blog. Unfortunately public instance can't handle all of the requests coming in. That resulted in some readers being unable to post a comment. That is why I decided to run my ...

Today I want to share three bookmarklets I love to use in development. You can add them to your browser, by creating a new bookmark and entering bookmarklet code instead of URL. Clicking on a bookmarkletI usually keep them in the bookmarks bar to make them easier to find. , will run the code snippet...

Two weeks ago I got a pair of cheap Xiaomi's wireless earphones. This was an experiment to see if I like true wireless concept before buying something more expensive. Sound # Most of the reviews out there are saying AirDots are lacking bass, but that sound is good overall. Long story short - sound i...

I haven't published anything in a while, which is a shame because I have a couple of good things to write about. That said, today's post is going to be a short one. I wasn't sure if theme is interesting enough. But in the end I decided to write it anyway. And it will help me get back in the writing ...

This time I want to share a small range slider (progress bar) I built. Check the demo. Code and documentation are available here. Same story again, on a React project we needed a media progress bar, and I ended up writing one myself. Why I didn't like anything I found? Well, everything I tried was m...

Let me start with a little disclaimer. Just because you can, doesn't mean you should use it. Hiding scrollbars can be bad for accessibility and user experience. But there are rare cases where it makes sense, usually when you have scrolling effects or when modal is opened. So use it wisely. Check the...

Exactly ten years ago, on my my friend's blog I published a blog post about Internet Explorer 6 CSS hacks. I remembered it recently, and thought it would be really cool if I republished that same post, on it's 10th anniversary. I added comments about the hacks from today's perspective to give you so...

Few days ago, I was chatting with our design team, and we were wondering how hard would be to create a fake audio spectrum (that mimics human speech) and visualize it. I immediately said it should be easy, and that I will play with it over the weekend. Of course, I didn't wait for the weekend, but w...

I want to brag a little - my npm packages have been downloaded more than 1 million timesStats are coming from npm-stat.com. this year! And I finally got a real domain: https://muffinman.io/ I've been quiet for the last couple of months. Mostly because I was busy with other things, both work and pers...

I love my Nintendo SwitchI have a huge draft about Switch, and how it have put the fun back in gaming for me. I hope to publish it at some point. Unfortunately, tonight I noticed that one of my Joy-Cons has two weird lumps on it. (This is the image from the internet, not mine.) On multiple forum thr...

This is something I keep rediscovering, because I keep forgetting it. JSON.stringify will omit all object attributes that are undefined. In most cases, it doesn't really matter, because if we parse that string back, and try to access that attribute - it will be undefined by design. Check the example...

I want to share a hack (or a trick if you prefer) my colleague Marko showed me today. What is the problem? We want our flex items to be equally distanced between each other and from the parent's edge. Unforunately space-evenlyI wasn't aware of this property, thank you Marc for mentioning it in the c...

Yesterday, one of my colleagues shared UI Movement website. It resulted in me playing with random animations trying to replicate mockups I liked. Here are the results:

This happened to me couple of times - borders would just randomly disappear in Chrome. All other browsers render them normally, but they just vanish in Chrome, on some screen sizes. Resizing helps sometimes, but I never was able to catch real pattern for reproducing. If this ever happens to you, the...

TL;DR # If you just want to add git version tag after npm publish add this to your package.json: "postpublish" : "PACKAGE_VERSION=$(cat package.json | grep \\\"version\\\" | head -1 | awk -F: '{ print $2 }' | sed 's/[\",]//g' | tr -d '[[:space:]]') && git tag v$PACKAGE_VERSION && git push --tags", I...

This is a weird one, and not something you will stumble into every day. But it is a bug nonetheless. On iOS safari, if you use window.scrollTo(0, y) and y is larger than document's maximum scroll, any immediate call to getBoundingClientRect will return incorrect top value.Same will happen for horizo...

Recently I switched to a new laptop and had to set it up to my likings.This comic describes my setup pretty accurately. My setup includes a bunch of small apps I found over the years. It seems that most people are not aware of these, so I decided to share a list. All of them are free (with the excep...

Today I learned: To upload files using fetch and FormDataFormData is supported in IE10+. you must not set Content-Type header. const fileInput = document.querySelector('#your-file-input') ; const formData = new FormData(); formData.append('file', fileInput.files[0]); const options = { method: 'POST'...

Some CSS fun. Lately I've stumbled upon couple of websites with elastic hover effect on buttons. Each one was using SVG morphing, which is fine, but I was wondering how hard would it be to implement it in CSS. It ended up up being pretty easy. I created four pseudo elementsOnly two pseudo elements (...

I've been really busy lately, doing both work and pet projects. At the moment I'm playing with three.js trying to clone old DOS game to JavaScript. Games (and animations in general) need animation loop in which we are going to update the scene and re-render it. Example animations are simplified and ...

Snippet for a rather popular requirement. Formatting a date in a nice way, using infamous "time ago" function. This is the basic version which I adapt to fit a specific project. To keep it easily customizable to your needs, I haven't packaged it up. Just pass a date to it, and function will return o...

This time we joined forces with our friends from IT Girls. They are promoting tech among women, and helping them start a career in it. Together, we are organizing a series of meetups and workshops about React. Last night, my colleague Nemanja and myself had a pleasure to give the first talk in the s...

React Router switched to component based routing starting with the version 4. Redirects are now done by rendering a Redirect component, like this:Please note that you can use included withRouter decorator but it can cause update blocking and introduce side effects. This is small subset of it. <Redir...
