Apache Online Tools

http://www.askapache.com/online-tools/

A collection of tools that come in handy - the image encoder is pretty helpful for embedding images.

App Icon Generator

https://www.appicon.co/

You have an image, but you need it in a ton of version for a mobile or macos app - couple seconds here and your done!

Bootstrap Navbar Without jQuery

http://codepen.io/Vincinho/pen/ZQBLGO

For when you don't want all that bloat but you need a navbar with a dropdown.

Draw.io

Need to make a flowchart or diagram real quick?

Favicomatic - The Favicon Set Generator

http://www.favicomatic.com/

Nowadays you need a whole set of favicons for your creations. This tool takes one image and does all the work. It's surprising how many "favicon generators" are still online and only give you 16 and 32 pixel icons.

How to Find or Validate an Email Address

https://www.regular-expressions.info/email.html

Validating email addresses is much more difficult than one would think until they have attempted to do so. Over the last 10 years or so anytime I have the need I consult this page first.

Ionicons Font Icon Set

http://ionicons.com/

It's like FontAwesome only slightly better looking IMO <del>and insanely easier to add to</del>. As of v5 this is no longer a fonticon set but instead a dynamic JIT javascript SVG loader. I keep the reference here because it's still a decent icon set and v4 is still available in github if you're looking for a customized/customizable fonticon collection.

Itsycal

https://www.mowglii.com/itsycal/

Another priceless macos utility. It puts a calendar in your system tray for immediately access whenever you need it. There's a similar yet delusionally priced app in the app store, but this one is open source and free to use.

MX Toolbox

Maintenance check for your mail server

MindMup

Fast, free online mind mapping.

Page Speed Insights

https://pagespeed.web.dev/

Despite the increased speed and bandwith of all connected things, the speed at which your site or app loads is more important today than ever. This google utility is always a good tool to check your work!

QiFi

https://qifi.org

Enable visitors to your home or office to connect to your wifi without a keyboard at all. Kind of fantastic! My only suggestion would be to add title, and text credential options ... and maybe stamping an image in the middle, but you can do that offline. For the security concerned it runs in the browser so the server (and network) do not see your credentials. For the real security concerned he spells out how to create the same QR code offline with a QR generator of your choice.

Rectangle

https://rectangleapp.com/

Organize your windows in macos. An ideal replacement for the now abandoned Spectacle app, this little utility makes moving your windows around, snapping them to a side or corner, splitting your screen between 2 or 3 windows - all a breeze. I now find it is one of the first apps I install on a new machine.

Skeleton CSS

http://getskeleton.com/

This is as bare bones as a CSS framework can be. If your needs are just enough to want a (prebuilt) grid system but nothing more this is a great starting point.

Standard Notes

https://standardnotes.org

Ever since Evernote changed directions and became undesireable I have gone through several alternatives, each with their own pros and cons. The only con here is you have to pay for additional editors beyond a straight text editor. Other than that they have security nailed down, syncing buttoned up and themes and other refinements making it everything Evernote isn't. Finally, it's completely open source so you can add anything you find missing.

Sublime Text Golang Setup

How to setup your Sublime Text as a Go development environment

Tailwind CSS

https://tailwindcss.com/

The problem with all CSS frameworks is they prescribe to one degree or another an overall layout and design. Picking the right one is generally a challenge of finding one that meets the needs and goals of your application or site. I would argue Tailwind is not in fact a framework at all but rather a toolbox of unopinionated utilities from which you can build your own framework.

Trello

https://trello.com

Kanban board with just the right amount of features

ValiDrive

https://www.grc.com/validrive.htm

Quickly spot-check any USB mass storage drive for fraudulent deliberately missing storage. Fraudulent USB/SD storage being sold through trusted marketplaces has exploded and using/trusting a bad drive can have immediate horrible consequences. Use this utility to CYA!

Wireframe.cc

https://wireframe.cc/

There a few new tools out there to mock up wireframes quickly. I ran through several options and found this one to be by far the simplest and easiest to use. Free for one offs, or pay for more features and an account to store them in.
