Open FaceTime Call from Command Line
11.4.2019
Communication tools are always associated with UIs, and for good reason — if you want communication to be easy and intuitive, you need easy and intuitive interfaces. We need communication tools to provide the lowest barrier of entry, since not all users will be tech savvy. For tech experts...
How to Reverse a Video
9.4.2019
One of my favorite media utilities is ffmpeg. This command line utility allows us to do some pretty amazing stuff like; Slice videos Convert video formats Modify video speed Combine audio and video Every once in a while I see a meme or funny video that reverses a video for effect. Since ffmpeg does...
AI-Based Video Preview from Cloudinary (Sponsored)
8.4.2019
The early days of video on the web weren’t great. We started with custom browser plugins and codecs, then moved to Flash, and eventually we found our way HTML <video>. Once we solved the technology problem, we started using more video for content and advertising. The next problem...
Awesome Automation and Integration with Buddy
2.4.2019
One of my favorite services for years has been IFTTT (If this then that). Having a service that allows me to trigger a host of functionalities with one simple action is amazing! Posting a picture to Instagram can trigger IFTTT to send a tweet, post to Facebook, email to friends, etc. I’ve...
Set Branch Alias with Git
28.3.2019
Version control systems can be difficult to use, especially when you don’t use a UI app. Just think about main branch or revision names: svn uses “trunk”, git uses “master”, and mercurial (hg) uses “tip”. I need to switch between mercurial and...

Set Commit Author with git or hg
24.3.2019
Knowing who authored a code patch is a sacred and important practice in the world of software engineering. Knowing the author gives the reviewer an idea of trust level, know who to ask questions about the patch, and gives credit to the genius of an important fix. There have been times when...
Adding Search to Your Site with JavaScript
20.3.2019
Static website generators like Gatsby and Jekyll are popular because they allow the creation of complex, templated pages that can be hosted anywhere. But the awesome simplicity of website generators is also limiting. Search is particularly hard. How do you allow users to search when you have...
I Don’t Hate Arrow Functions
19.3.2019
TL;DR Arrow functions are fine for certain usages, but they have so many variations that they need to be carefully controlled to not break down the readability of the code. While arrow functions clearly have a ubiquitous community consensus (though not unanimous support!), it turns...
Write Your First Service Worker in 5 Minutes
18.3.2019
What is a service worker? A service worker is a little file that will allow you to cache files and other assets on a user’s machine. How is this different from server-side caching? Because the assets are stored on a user’s machine, rather than a server, there is no need to go across...

How to Set Commit Author
13.3.2019
I’ve worn dozens of hats on a dozen different teams during my time at Mozilla, but none has been as rewarding and challenging as community management. Whether it’s mentoring students, welcoming new contributors, or reviewing pull requests, there’s always so much to be done....
Get File MIME Type from Command Line
28.2.2019
I’ve gotten skilled at shell scripting over the years. I love a good GUI but knowing how to automate makes you a much more powerful engineer. Much of my scripting requires recursing over directories and processing a file if it meets a given criteria, which is often file extension or MIME...
List USB Devices from Command Line
27.2.2019
I was recently creating a Recalbox with my 5 year old son and it was an awesome experience; I saw the excitement and curiosity in his eyes while helping him put together a video game machine. We added NES, SNES, and Nintendo 64 games to the device but it became apparent that the N64 controller...
JavaScript Proxy
26.2.2019
I’ve always loved the flexibility of Objects and prototypes in JavaScript, but for a long time, I felt that a level of dynamism was lacking. JavaScript eventually added get and set methods for object properties, which was an awesome step, but there was still room for improvement....
Chris Coyier’s Favorite CodePen Demos IV
25.2.2019
Did you know you can triple-heart things on CodePen? We’ve had that little not-so-hidden feature forever. You can click that little heart button on any Pen (or Project, Collection, or Post) on CodePen to show the creator a little love, but you can click it again and again to heart it just that...
Awesome Analytics with Keen.io (Sponsored)
21.2.2019
As a young developer, I would often make decisions based on what I considered to be common sense or what I would envision appealed to users. What a mistake. As I’ve become more experienced as a developer and a businessman, I’ve realized that analytics are the best way to make...
Building a Landing Page Fast Using the Visual Composer Website Builder (Sponsored)
20.2.2019
What if it were possible to build a landing page from top to bottom, including a header and a footer, and do so without any need for writing code? And even if it was possible, could you reasonably expect to do so as easily and quickly as putting together a puzzle designed for children...
