This is a little funky script to intercept AJAX requests and raise a simple custom event for everything else in your app to listen to. To use this, you just need to listen for a custom event named `AjaxDetected`. The method, url, and any data is passed in the event detail. document.body.addEventListener(‘AjaxDetected’, function (e) { […]

We have now reached the tipping point with dark mode on The World Wide Web. Support has reached the point of broadness that means users who are browsing on their mobile phones are going to notice what you are doing to their eyes if you don’t support it. We will soon pass from “users are […]
Rate Limiting Googlebot Across Many Websites
Googlebot is one of the good guys. It will check your robots.txt file and respect any crawl delays you’ve asked it to use. However, if you run hundreds or thousands of websites across your infrastructure you can encounter waves of Googlebot traffic due to it coincidentally selecting many of your websites to crawl at the […]
This might be a bit niche, but I needed to collect RGB values in an Excel spreadsheet and I though it would be neat to preview the colour in another cell. To cut a long story short, the only way I could make this happen was with a bit of Visual Basic for Applications. It’s […]
Execute Raw SQL Scripts in Entity Framework Core
Most of the time, Entity Framework Core will just do the right thing. Every now and then, though, you’ll find that it’s doing something in a bit of a sticky way and you’ll want to take control. Usually it’s when you’re deleting a range on a table with cascading deletes. Here’s an example of the […]
Simple Conditional Updates to Entities in ASP.NET Core MVC
When you accept a view model in your .NET Core MVC application, you can request that only certain fields are bound, like this [Bind(“Title”)]. Neat. But when you want to apply the changes to your domain object, you often want to do a similar thing and only update certain fields (and only if they really […]
Remove Blank Lines From a File with PowerShell
When importing a file full of data into a test system, I discovered that the CSV library I was using to do all the work was stopping when it reached a blank line. That makes sense, it thinks the data has ended. On inspection, I found quite a lot of blank lines, so there was […]
Use PowerShell to Send All Regex Matches to a New File
Yesterday I had to look at a list of stuff on a third-party website and match it up to a list of stuff we control. It took quite a bit of time and some Excel shenanigans to complete the task and as I know it’s going to crop up again, I decided to employ PowerShell […]
The type or namespace name ‘ApplicationInsights’ does not exist in the namespace ‘Microsoft’
If you uninstall the Application Insights package from a .NET Core MVC project, you might get a few errors as it can’t “remove all the references” that might have made it into your application. The changes to StartUp.cs will be pretty self-explantory, but elsewhere you will get something a bit more off-the-wall as it references […]
Although it has been abused with an enthusiasm that borders on the insane, there are good reasons to use the Notifications API in your web apps. For example, you write a mail client that allows the user to request notifications for key contacts… if they are browsing your web-based app, they should get notifications. To […]
