AI Street View / / No Comments Today I have mainly been creating AI generated Street View scenes of historical locations. The result is AI Time Travel Street View, a little virtual world of 360 degree panoramas which you can wander around in while exploring Medieval France, Renaissance Venice and Victorian London (as dreamed by AI).Navigating around AI Time Travel Street View is fairly intuitive.

How to Use Your Domain on Bluesky / / No Comments Bluesky is a hot new social networking platform that functions like Twitter from Twitter’s original founder. New users are flooding into the platform as a respite from Elon Musk’s vision of Twitter and the fumbles that have happened since his takeover. Upon signing up for Bluesky, your username defaults to {yourdesiredhandle}.bsky.social, but there’s a better and more secure option. One of Bluesky’s awesome features is the ability to base your username on a hostname’s DNS record. In short, if you control a hostname’s DNS, you can essentially verify yourself.

Updating and Supporting URL Parameters in JavaScript / / No Comments Not quite a long time ago, but roughly two years ago I wrote a blog post on updating and supporting, URL parameters with Vue.js. The idea was this: Given an application that lets you perform various tweaks, it would be nice if the URL was updated to reflect the current state of the application. This would let you bookmark, or share, the URL with others and they would get the same view as you. In that post, I built a very basic "data filtering" application and then updated it to support updates to the URL. I thought I’d revisit that post and demonstrate building it in vanilla JavaScript. As always, I’d love to hear your thoughts on this, especially if you’ve done something... more → Posted in: JavaScript Tagged with: JavaScript, Parameters, Supporting, Updating

CSS content-visibility / / No Comments The CSS language is full of small gaps which are frustrating to navigate. Between CSS properties to hide a container and its contents, there is still room for improvement. visibility: hidden keeps height and width integrity while display: none on a container hides everything. You can use .container > * to hide all contents of a container, but what if there was a better way? There is a better way to hide the contents of an element while respecting the container’s border and dimensions. That better way is using the content-visibility property: .my-container.contents-loading { content-visibility: hidden; } A demo of such functionality: See the Pen Untitled by David Walsh... more → Posted in: JavaScript Tagged with: contentvisibility
