This is not something common, I guess. Imagine with me, will you? You have an app dedicated for reporting. The sole reason you built this app is to allow non-developers, but data savvy people, to create operational reports for LOB applications. How do you ensure that your users will not use this solution to modify data on the fly? Imagine how fun would it be to explain why your reporting solution allow them to modify data to your boss....
There is a pattern here, I think. I don’t like to work with dates and you probably know that by now. Anyway, don’t like them, got to work with them. In this episode of Pains against dates, I wanted to write about something very specific that I had the pleasure to troubleshoot last week.

By default, axios will use JSON.stringify to convert an object to a json....

I ran into this issue not too long ago and found that my favorite web service tester Postman doesn’t support sending multiple messages concurrently.

Note that the implementation below is mostly a copy with the following changes: The list view is grouped Each item in the list can have an icon In the AddPage methods, we no longer create an instance of the pages added, we just add a light reference to a collection The menu page is a xaml file instead of fully created in code Only when the menu item is tapped we instantiate and display the Page and ViewModel LazyLoadedPage class:...
