Function Friday: Data Type Conversion Functions - Arrays, JSON and XML

This time we’re wrapping up the last of the data type conversion functions. We’ll cover the more complex data types: arrays, JSON, and XML. array The array function creates an array from a single input data element. The format is simple: array('<value>') And as an example: array('hello there') // returns ["hello there"] To be honest, there’s no reason to use the array function. The createArray function allows you to pass in multiple data elements and you get the same result.

Using Application Insights For Better Application Logging

As you gain more experience as a developer, you soon realize the importance of good logging for your applications. When an app is small, you can get away with console logging, print statements, etc. But once your app reaches any real size or functionality, especially as you reach your MVP state, it’s time to have some real logging. For that, we can turn to Application Insights. Application Insights is an Azure cloud-hosted logging platform that you can use to keep track of the performance and errors in your live web apps. As the Microsoft docs put it, you can use App Insights to “automatically detect performance anomalies, diagnose issues, see what users actually do with your apps, and help improve app performance and usability”.

Function Friday: Binary, DataUri, UriComponent, and Base64 Conversion Functions

This time I’m going to delve into conversion functions for base64 and binary. Both are typically used to convert binary files such as images and zip files back and forth between formats that various connectors need in order to process them. It’s also sometimes used to generate hashes used for checksums, certificates, and encryption. base64 The base64 function is used to convert a string into a base64 encoded version of a string. The pattern is:

Power Automate: Connectors from Independent Publishers

One of the most fantastic parts of Microsoft Power Automate is its ability to connect to a massive array of other systems to push and pull data. Early on this was restricted to those systems that Microsoft had created connections to or had worked with external vendors to develop connections to their systems. In recent years, however, they added the ability for people to create their own connectors to external systems and to share those connectors with the community at large. There are now a huge number of Microsoft-approved community-created connectors available for Power Automate. In this post, I want to highlight a few of my favorites.

Guest Post: What are the different types of interviews?

I’ve got a guest post this week provided by the Codementor team. Thanks to them for providing this, and I encourage you to take a look at what they have to offer. Your resume got you in the door. What awaits you is a big hurdle: the interview process. Whether it’s a one-on-one interview with the manager, a group interview with the entire team, or multiple interviews of all types, you’ll have to pass them to land the job.

A Brief Introduction to Azure Data Factory

Over the last year or so I’ve had a chance to delve deeply into one of Microsoft’s newer Azure offerings: Azure Data Factory (ADF). This post is a summarized version of a talk I’ve given at a few conferences and meetups in recent months. A huge part of what we deal with in tech is data. It’s everywhere, and it’s only getting bigger. It used to be that if we needed to move data between different systems or data sources, we would have to spend hours, days, or even weeks writing some custom integration that would take the data from one system and convert it to be imported into a different system.

Function Friday - Data Type Conversion Functions - Bool, Decimal, Float, Int, String

For this batch of functions, we’ll start delving into the data type conversion functions. For the first group let’s look at the base type conversions. They all work pretty much the same way. Bool The bool function is used to convert input data into boolean form (i.e. true or false). The format is pretty straightforward: bool(<value>) The value can be of number or string data types. The output depends on the data type of the input. Numbers all work the same way, whether it’s an int, float, or decimal. If the input number is 0, bool returns false. If the input number is any other value, positive or negative, and the result is true.

The Ethics of Being a Software Developer

There’s a lot of pain in the world right now. In nations where freedom exists, the rights and privileges of their citizens are eroding away. The world is changing. Freedom is under attack from every corner and by every means possible, be it war, oppression, apathy, or the destruction of rights by those who have been entrusted to uphold and sustain those rights. As technologists, we have a duty and responsibility to evaluate our roles in those changes.

Function Friday - Collection Functions: Contains, Item, Join

For the last group of collection functions, we’re taking a look at the functions that focus on the items in the collection itself. Contains The contains function details whether or not a collection contains a specific element. The result is a boolean value (true/false). The pattern is as follows: contains('collection', 'value') contains([collection], 'value') The exact way it works depends on what the collection is. If the collection is a string, the contains function works to find a substring of characters.

My Being Fired/Laid Off Horror Stories

So I saw a tweet in my stream a couple of days ago that got me thinking a bit about my own job history, especially in tech. First “real” job. Mostly research. Acted as office receptionist. I was replaced by a bell. I made the bell business cards on my last day. https://t.co/Jztrw4kEFG — emily freeman 🇺🇸🇺🇦 (@editingemily) June 15, 2022 For the most part, every job I’ve ever left has been on my own terms. It might be for a better opportunity. It might be because I was fed up with the state of the company I was working at. But almost always I left when I decided it was time to go…. with 4 exceptions.

Function Friday - Collection Functions: Intersection, Union, Skip, Take

For the second batch of collection functions we’re taking a look at the functions that let you work with the collections themselves. These functions let you slice, dice, and merge one or more collections together. Intersection The intersection function compares two or more collections and returns a new array that contains only the elements that exist in all the passed in collections. The format is as follows: intersection(collection1, collection2, ...) As with all the functions, you can pass in collection variables or literals, and strings are treated as character arrays.

Function Friday - Collection Functions - First, Last, Empty, Length

Power Automate contains excellent support for working with collections of objects. Generally, these will be treated as arrays of objects. However, these functions will also work with strings as, in Power Automate, strings are also considered a collection, as they are essentially an array of characters. As such, Power Automate contains a good selection of functions for working with these collections. For my return to functions in Power Automate, we’ll take a look at the first group of collection functions: First, last, empty, and length.
