8 Digit Hex Colors

16.7.2018
One of the most requested capabilities in my early days of web development was the ability to set opacity on elements and even PNG images without the need for browser-specific CSS or hacks.  Eventually we got native opacity support and even enjoyed rgba(), the ability to cite an opacity level with...

Script & Style Show: Episode 15: CSP with Scott Helme

14.7.2018
In this episode:  Todd dials in from a poppin’ KCDC while David dials in with a massive headache.  Scott Helme dials in from lovely Manchester to discuss web security, specifically the criminally underused CSP API.  Join us to learn what CSP is, why it’s important, how it works,...

Search Git Commits Between Dates

12.7.2018
One of my weaknesses as a developer is relying on UIs to provide me the data I need.  It’s not a fatal weakness but it does hamper me a bit.  One prime example is relying on GitHub’s interface to review changes; git’s command line provides the information needed with commands...

Hide Information in Images

9.7.2018
If you’ve followed this blog, you know that I’m obsessed with figuring out every way to interact with, abuse, and convert different types of media.  Whether it’s images, video, or audio, if something can be changed or exploited, I want to figure out how to do it. I remember...

React Node Flow

27.6.2018
Flow, the static type checker used in many React projects, feels like a gift and a curse at times; a gift in that it identifies weaknesses in your code, and a curse that sometimes you feel like you’re needlessly adjusting your code to satisfy Flow.  I’ve grown to appreciate Flow...

Count Frames in an Animated GIF

26.6.2018
The animated GIF always makes me chuckle; on one hand they seem like a relic of the “old web”, on the other hand they aren’t going anywhere and their meme-like presence seem to only make them more popular.  If you browse through my media blog posts archives, you’ll notice...

Easy Document Signing with the Eversign Chrome Extension

25.6.2018
A while back I wrote about Eversign, an awesome service that allows you and your clients or partners to digitally sign documents online.  If you’ve recently bought a house or did any other large purchases or agreements, you know how important the ability to reliably sign documents online is. ...

Convert HTML to Markdown

21.6.2018
One of my biggest mistakes with this blog was not finding a WordPress plugin that would allow me to write my posts with markdown; to this day I still need to write posts in “Visual” mode and then manually convert the post to HTML for “Text” mode.  One of these days I want...

Show FPS for Steam Games

18.6.2018
There’s nothing more frustrating to a top gamer (outside of bugs in a game) than dropped frames in a video game.  If you’re playing a competitive multiplayer game like PUBG or Fortnite, where up to 100 people are simultaneously competing, dropped frames can be the difference between...

Uppy File Uploading

11.6.2018
One of the big tasks I was charged with at my first job was setting up a system by which any customer or potential customer (aka anonymous user) could upload PDF and image files. I had loads of constraints to deal with: browser support, server settings, variance in user tech knowledge, etc....

console.logTime

7.6.2018
I work on a really complex debugger at Mozilla but, and don’t tell my colleagues, I sometimes enjoy simply using console.log and other console commands to get some simple output.  I know, I know, but hey — whatever gets the job done.  A few years ago I detailed console.time...

What’s Next for Hybrid App Developers? (Sponsored)

5.6.2018
The story of hybrid application development is a never-ending one. Each framework has to continuously strive and innovate to remain relevant, and the discussion of which framework to use is a question often asked. Most hybrid applications are built using a combination of HTML, CSS, and JavaScript....

Script & Style Show: Episode 11: Ionic Framework with Max Lynch

1.6.2018
In this episode:  David blames his wife for getting sick and missing last week’s show, Todd’s got a new Jeep, and David then blames his wife for not letting him have a Jeep.  Oh, and Max Lynch of Ionic Framework fame stops by to talk about Ionic, Stencil, Web Components, the state...

OpenRates Currency API (Sponsored)

30.5.2018
Creating your own APIs can be a total nightmare: worrying about uptime, load balancing, data accuracy, caching, and all of the other risks would keep me up at night.  And if your API relates to money in any way?  If you get that wrong you could be costing yourself, your employer, or your client...

How to Delete Untracked Files in a Mercurial Repository

29.5.2018
Working around Firefox at Mozilla means that you need to get acquainted with mercurial, the version control system that rivals git and svn.  Like any tool, hg (mercurial) can be difficult until you’re well versed with it.  And if you hg import a URL that doesn’t match up with...
