With the release of Ktor 2.0, one of the migrations I had to do was for Firebase Authentication which I first learned about how to use with Ktor 1.6 from this medium article last year. Learn how to setup Firebase Authentication with Ktor 2.0 and how to test it.

If you have ever shipped a feature with a scrolling list, a product manager will usually ask you to track when an item in that list is viewed by the user. With Jetpack Compose being somewhat new, I was curious how to solve this problem with respect to a LazyColumn so let’s learn how to know the second eyeballs see items as they scroll into view!

I was perusing Reddit the other day when someone asked how they could use SavedStateHandle with a StateFlow similar to the SavedStateHandle.getLiveData() version. The most upvoted comment originally was saying that this functionality is not officially supported, but one could convert the LiveData to a Flow using the LiveData.asFlow() extension function. That seemed pretty simple for anyone to do, however testing that would then require using LiveData in your tests which might be annoying if you were using StateFlow to manage state. So after looking over the API, it seemed pretty simple to write a wrapper that could expose this functionality directly as a StateFlow and that is how the SavedStateFlow library was made!

Working at an enterprise that needs a custom component library with each component being its own snow flake and having more complicated logic than the next. I found myself needing a way to test the logic in these views to ensure I could iterate quickly and not break anything in the process.

One day at my day job, I noticed that there were a couple of services we used that anytime an event happened there was a very manual process for the developer to copy paste data into a Slack channel for others to be aware of the issue. I thought there had to be a better way to automate this whole process and prevent a developer from having to do this tedious task. That was when I came up with the idea of creating a Slackbot application to do this. So in this article I will describe the process I went through to create a Slackbot using Ktor and webhooks that can post messages to your Slack channel of choice and how to deploy to Heroku. For this example, we will be using Github webhooks to supply data to our Slackbot but the same principal applies to your service of choice that offers webhooks.

If you have a project, blog, or documentation that you need to have hosted in a site, Github Pages can be a great way to host your site for free straight from the repository.

One aspect of a programmer’s work that I think can get overlooked is the actual physical workspace where he or she works. Over the years I have invested a lot of time and effort into creating a home office that is ergonomic and promotes a workflow that works for me. By no means am I trying to tell everyone that…
