Solutions and Tools for Dealing with Broken Links in Web Pages

A couple of months ago a post by Leo Blanchette got to the front page of Hacker News and there was an interesting discussion on dealing with broken links and external content – the main problem being links that become out of date due to paywalls, altered content, or content getting taken down.

I’ve been running this blog since May 2008. If you’ve run a content-driven site for even a fraction of that, you know that link rot is a problem. In this post I’ll go over some of the suggestions in that thread along with some tools to use to check for broken links.

A Review of ipwhois.io for Reliable Geolocation Data

[Sponsored] If you’re building an app that requires delivering a dynamic experience based on the user’s location or other location-related data, a fast and easy-to-use Geolocation API will certainly come in handy. One such option is ipwhois.io. The service, which is free for small non-commercial projects that need fewer than 10,000 requests per month, is easy to integrate with your tech stack.

As usual, it’s always best to look at a few examples so you can see it in action. Their documentation is short and easy to follow, so I’ll demonstrate using the following example request:

YouTube’s Time-Based UX Problem for Live Sports

I like to play beach volleyball here in the Toronto area. I also watch beach volleyball on YouTube, which includes a lot of live streams from the AVP league in the US. It's a fun sport that I recommend to anyone looking for a new athletic competition to follow.

In most leagues and tournaments, beach volleyball games have a 3-set format, with each set finishing when a team reaches 21 points (or higher if they're not yet ahead by 2). The third set (played if needed) will go up to 15 points (again, win by 2). Some leagues/tournaments will play all three sets up to 15. It depends on the venue, tournament, etc.
