Introduction Authentication has been an important component in the world of IT from the time companies required their employees to prove their identity to use the company’s computing resources whether it was to execute its business processes or accessing email or file. During the earlier days employees used to login to their computers using a username and password, which was stored in a central server like an active directory (in case of Microsoft tech stack). With the active directory credentials employees where able to use to login to both their windows computers as well as the email application both of which were in the same network. This approach worked well for many years until the softwares and services that the companies used where no longer within their network. While active directory protocols like NTLM or Kerberos could work across external networks via technologies like VPN it was complex to setup and maintain such an infrastructure while keeping all the connection secure and stable. Also with growing number of users/services and the pace at which the growth occurred, these technologies were not designed to scale at that pace. Hence new Authentication mechanisms were needed. ...

I recently came across the site https://cloudresumechallenge.dev/ and decided to give it a try using Azure services. To start simple I decided to ignore the DB, CDN part etc and just have the the UI and the middler layer of the app. Below is the high level architecture. The front end of the app will be hosted a static web site in Azure Blob storage. Backend will be an Azure function that will feed the resume data to the frontend over HTTP, the azure function will be a HTTP triggered function. Currently the resume data in JSON format hardcoded in the Azure Function code. As an upgrade to the app, the JSON data can be moved to a CosmosDB instance and put an Azure CDN in front of the UI to deliver content fast to users. ...

This is a continuation from the previous article on feature flags implemented using Azure App configuration service to maintain the flags. Just to reiterate, feature management can be implemented using config files but this article is trying to implement feature flags connecting to Azure App configuration service. Introduction The previous article described about implementing a boolean feature flag to turn on/off a feature. In this article I am trying to implement a custom feature flag. Microsoft provides few predefined custom feature flags or feature filters (as they are called) Targeting, TimeWindow, and Percentage (more about it here), which covers most usecases, however, there might be situations where you find the predefined ones falling short. In this article I am building a filter ground up with a made up custom logic. ...

Feature flag is a very popular practice in modern application development, which is used to specifically hide features implemented that are not yet ready to be used by wider audience, and when ready can be enabled by a flip of a switch. The flags can also be used as a kill switch for application feature when it not working as expected. With feature flags implemented, it would be effective to have the features enabled or disabled from a location outside of the application infrastructure or configuration, this way we can have features spanning across applications be controlled via a centralized flag. Azure has feature management as part of the Azure App configuration service which can manage feature flags and maintain it separate from your hosting model and will act as a centralized repository for feature flags. Microsoft also provides libraries for different programing languages to consume Azure App Configuration service. More about it can be found here ...

I have been reading the Blazor 5 documentation and decided to create a simple project to give its features a try. As always, there were a ton of ideas in my mind but while scanning through dev.to i came across a post by Aleks Popovic, where he made a Radio player using react, so i decided to create one using Blazor 5. I used the same service as Aleks to get the radio stations, called the Radio-Browser. ...

If you have landed here searching how to switch off auto formatting of code files in Visual Studio, you are either a code purist who does not like the formatting the IDE is performing or you are like me editing a large auto-generated class file (due to unfortunate situations) and Visual studio hangs or crashes on you every time you do a small change. The good news is there is an option in the IDE to switch feature off. Through out the generations of visual studio this option may have moved between sections, but fortunately been called the same. The flag you are looking for is ...

Problem We all have seen and annoyed seeing those google ads or facebook ads on websites and apps. Mostly of the times the ads over takes the actual content of the website, especially on those forums. Ads also shows up on free email services, apps on your phones, smart tv, they are everywhere. More than annoyance, they eat up a lot of bandwidth and ofter makes the website/apps slower to respond. There are ad blockers available for your browsers, but that just solves the problem on that device, but devices like smart tv doesn’t have an easy way to block ad on the device. ...
