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,...

Every new year brings about a sense of optimism that the next 365 can bring about big, positive changes in different phases of life. That’s no exception for me and this blog. I did pretty well with last year’s goals, so I thought I’d push myself again with a new set of goals. Be...

2019 Year in Review

5.12.2019
The beginning of every year starts out with all of us setting ambitious goals — goals being personal and professional. Many of us rarely complete half of those goals, most abandoning them by the end of the year. In January of this year I published my list of goals for the year. Let’s...

Mirror Android Device to Computer

26.11.2019
As I continue my adventure into Android development, pair programming has been a huge help in learning this new platform. When it’s time to build and run the app, relying on the emulator is a fools’ game — the emulator is slow and it’s hard to reliably simulate gestures....

Image Lazy Loading

25.11.2019
Lazy loading images is a practice that’s been popular for a decade and for good reason: images are usually the heaviest downloads on a given webpage and avoiding unloading images that are never seen saves the user bandwidth. There are plugins for lazy loading images in every JavaScript...

Real-Time Google Search Results API with serpstack (Sponsored)

19.11.2019

JavaScript waitForTime

6.11.2019
I write a lot of tests for new features within Firefox DevTools. We have hundreds of “mochitests” which open the browser and perform synthetic actions like clicking, typing, and other user actions. I’ve previously written about waitForever which essentially halts following actions...
