The repositories of distributions such as Debian and Nixpkgs are among the largest collections of open source (and some unfree) software. They are complex systems that connect and organize many interdependent packages. Is it possible to capture the large scale features of such a repository in an image? Are there common design choices of the contributors? Did they lead to any emergent structure? This work resulted in some beautiful (and interesting) visualizations. Here’s a sneak peak 👇

React Quantum parses through your React application to create a color-coded tree model of its component hierarchy. On hover, each tree node will display two key component performance metrics—render time and re-render frequency—as well as memoized state and props to indicate what, specifically, initiated the render.

Venn diagrams are great for explaining set operations such as UNION, INTERSECT, and EXCEPT, but they aren’t so great at explaining JOINs: A JOIN is really a cartesian product (also cross product) with a filter. Turns out there’s a better way: JOIN diagrams, which I’ve never even heard of. Click through to read all about ’em. 🤓

This “Data Color Picker” looks like a spectacular tool for any developer out there (like myself) who appreciates the value of a good color palette, but lacks the ability to put one together. You’re not alone! (This tool is for generating equidistant palettes for data visualizations, but it can most certainly be used generically.) Creating visually equidistant palettes is basically impossible to do by hand, yet hugely important for data visualizations. Why? When colors are not visually equidistant, it’s harder to (a) tell them apart in the chart, and (b) compare the chart to the key. I’m sure we’ve all looked at charts where you can hardly use the key since the data colors are so similar. You pick the “endpoint” colors and it generates all of the colors in-between. Very cool.

Cool idea: take Google’s autocomplete suggestions, repeat the same query on them, take those suggestions, repeat the same query on them, and then draw a line between each suggestion. This could be useful for market research, to find alternative solutions, or simply for curiosity’s sake.

This was announced in late March, but I missed it back then so maybe you did too. Our goal was to more easily enable anyone to explore the health of the web as a whole. Not just data-mining SQL gurus or statisticians, but everyone with a vested interest in the state of the web. An excellent goal, indeed. How did they do? Well, they added a bunch of awesome reports and consolidated traffic data between mobile and desktop devices. If you hadn’t bookmarked this site previously, now is the time.

Nice visualization where the nodes are programming languages and the edges are compilers. Here’s an example showing JavaScript as the compile target 👇

As we know, an “Ask HN: Who is Hiring?”(example) post will occur at hackernews every month. It is interesting to scan the post because it helps you to get a feeling about what is happening in tec related busness. Aim of this repo is to give you a feeling about how the tec job requirements/used tools/kind/… evolves. React and Blockchain jobs on the rise…

I hope this service doesn’t promulgate the GitHub-profile-as-resumé meme, because it’s definitely cool and fun to let it crunch the numbers and visualize what you’ve been up to all these years. For example, it determined that my most productive days are Mondays. I didn’t know that!
