How to Specify User Agent with cURL
25.2.2020
Over the years I’ve shared how to perform a number of actions with cURL: how to send POST data, how to retrieve headers, follow redirects, check GZIP encoding, and more. Another useful cURL directive is sending the user agent, as some servers respond with different content or headers...
View Mac Calendar from Command Line
24.2.2020
As someone that loves using UI tools, I do pride myself in learning how to accomplish the same feats from command line. Don’t believe me? Check out my Command Line tutorials section — I guarantee you’ll learn quite a bit. Recently I learned that you can view basic calendars from...
Lazy Object Initialization
17.2.2020
The Firefox DevTools underlying code, which is written with JavaScript and HTML, is a complex application. Due to the complexity and amount of work going on, the DevTools team has done everything they can to load as little as possible. Furthermore the team has a system of lazily importing...

Whether you’re an experienced pro or someone new to the industry, finding a great job can be a scary, stressful process. Engineers and designers get inundated with Hacker Rank tests, portfolio requests, and a variety of other queries. Vettery improves the experience for free agents...
Override window.alert
11.2.2020
For years the only bit of feedback web developers could get was via alert("{str}") calls. These days we have the web console but, in rare cases, we don’t have a console and alert calls are our only window into a value at a given time. One problem: if an alert sneaks into production code, your...

Getting Fancy with position: sticky;
7.2.2020
Mike Solomon worked on a fancy scrollytelling post for Esquire and blogged about it. It has GIFs of each step along the way of figuring out not just position: sticky; but also using negative margins, wrapper divs, backgrounds, and even a smidge of JavaScript measuring to get it all right.
What...
Awesome Forward & Reverse Geocoding API: positionstack (Sponsored)
6.2.2020
One awesome web functionality we take for granted is geolocation. Based on geolocation data, we can get someone to their destination, provide them suggestions based on their location, and so on. One downside of native geolocation, especially in the browser, is that it’s limited in both input...
Git Branch Autocompletion
4.2.2020
Naming git branches is something most of us have down to a science. My branch naming pattern is usually {issue number}-short-feature-description, though many developers prefer to lead with the description and end with the issue. Regardless of the pattern you use, having a feature like autocomplete...
Use and Reuse Everything in SVG… Even Animations!
28.1.2020
If you are familiar with SVG and CSS animations and started to work with them often, here are some ideas you might want to keep in mind before jumping into the job. This article will be about learning how to build and optimize your code with <use> element, CSS Variables and...
Flexible Captioned Slanted Images
25.1.2020
The end result of Eric Meyer's tutorial on creating this row of slanted images is pretty classy. But it's more about the journey than the destination (there isn't even really an isolated demo for it). Eric does an amazing job at talking it through like a thought process.
We did that recently, only...
Min and Max Width/Height in CSS
24.1.2020
Here's a nice deep dive into min-width / min-height / max-width / max-height from Ahmad Shadeed. I like how Ahmad applies the properties to real-world design situations in addition to explaining how it works. In the very first demo, for example, he shows a button where min-width is used as a method...

20.1.2020
An IP address is a simple, numeric piece of information that gets passed to a server, but that IP address can provide a wealth of information with ipdata. With ipdata you can learn user location, language, currency, and much more! Quick Hits ipdata is an IP Geolocation and Threat Intelligence API....
Animate Text on Scroll
13.1.2020
We covered the idea of animating curved text not long ago when a fun New York Times article came out. All I did was peek into how they did it and extract the relevant parts to a more isolated demo.
That demo is here:

Fantastic Flight API with aviationstack (Sponsored)
9.1.2020
I didn’t fly until I was 25 years of age — I was hopeless in knowing I had to be there early, the process of security, and the whole gate structure. Now that I’ve flown dozens of times for Mozilla, I feel much more comfortable with the process of flying, but feel less comfortable...

IBM and Farmer Connect debuted a blockchain app that allows consumers to monitor the coffee supply chain
Duplicated Argument Names
6.1.2020
Oftentimes we override or monkey patch functions and, in many cases, there are arguments we don’t care too much about. A common practice for those arguments is using _ for argument names — it’s a generally accepted and known practice for “this isn’t important”....
Validate CSP from Command Line
2.1.2020
The content security policy spec has been an amazing front-end security tool to help prevent XSS and other types of attacks. I’d go as far to say that every site should implement as specific CSP as possible. If you aren’t familiar with CSPs, here’s a quick example:...
A CSS Tribute to SVG
31.12.2019
This demo from Jérémie Patonnier is incredible. Make sure to look at it in Firefox because some Chrome bug apparently prevents the entire thing from working.
The big idea is that the entire demo is one <rect> element. That's it. It is duplicated with <use> elements when needed,...
