Thoughts on the Episerver/Optimizely Acquisition
When one of the market leaders in digital experience / content management / e-commerce acquires the market leader in Optimization and Experimentation - great things can be expected. But how will it differ from the optimization techniques used by Episerver customers today? Here are my thoughts.
Profile Manager v2 - KQL edition
We just launched a new version of the online tool Profile Manager - a tool that makes it easier for developers and content analysts to work with Episervers Profile Store. The new version lets you easily try out different KQL queries and build Filter Definitions with them.
Episerver Forms: Avoiding spam with a honeypot
Spam comes in many forms and can be really annoying. Often, when you put a form on your website it will be found by spam bots that will post lots of spam in the form. A common defense is CAPTCHA's, but they are annoying the real users and typically not WCAG compliant. Here, I'm showing a simple Episerver implementation of another approach that works wonders for me - the honeypot.
Experimenting with Wikipedia topics for Content
Automatically tagging your content with topics from a known, well described topic base like Wikipedia can have many cool uses. You can organize your content, suggesting keywords and outbound links, not to mention that you can build up interest profiles of your visitors. These interest profiles can the be used to suggest appropriate content and keep your visitors engaged. Inspired by Episerver Content Intelligence and a couple of earlier projects I've done in the past, I decided to perform an experiment to see how far I could get with a DIY approach as opposed to the traditional cloud-based NLP/AI.
Reading very large gzipped json files in c#
This is a little code snippet that I often find quite handy. It's a piece of c# code that opens a gzipped json file and iterates through the items in it. Since it takes it piece by piece (as opposed to loading everything in memory) it's can pretty much handle files of any size.
Showing the right block types at the right time
Often, it can be handy to have very exact and dynamic control over what editors can see or do. One of my weapons of choice for this is the good, old and trusted Virtual Roles. In this scenario we have a multi-site Episerver, where some of the block types it should only be possible to use on one of the sites.
Enrich Episerver Forms with additional system fields
Episerver forms adds a couple of system columns to each form submission when you export the submissions. But it happens that the people that need the form submission reports want additional data - for example the url of the page the form was on - and for some reason they don't know all Episerver page Guids by heart.
Exploring the Episerver Nuget Feed
The best thing about Episerver is the community and all the great contributions coming from it. Many of them make it into packages on the Episerver nuget feed - along side Episervers own packages. I have for a long time worked on building tools to explore and visualize this more - and now I'm finally ready to one-by-one share some of the tools coming out of it.
Using Episerver Forms to book meetings in Outlook with Microsoft Power Automate
It's not as hard as you might think - and doesn't require any code - to connect your Episerver Forms with hundreds of other systems, using services like Microsoft Power Automate (formerly Flow), Azure Logic Apps, IFTTT or Zapier. I made a 5 minute video, showing how you can let your visitors request a meeting on a given date from a form on your website, and then having it being automatically booked in your Outlook 365 calendar.
