Finding your motivations for success

You didn't come this far to only come this far - Finding your motivations

Recently I was faced with some difficult decisions regarding employment. I had been experiencing some internal strife and as a result was “open to new opportunities.” While I hadn’t been actively pursuing options I figured that if something came along I’d at least consider it. Eventually some opportunities interesting enough to pique my interest did hit so I began the process. Nearing the end of my “openness” some external events occurred that set up an interesting situation. Ultimately I was faced with a decision that required me to understand myself and work at finding my motivations.

MsBuild error publishing ASP.NET MVC referencing .NET Standard library

MSBuild error - This version of Microsoft.Web.Sdk used by this project is insufficient to support references to libraries targeting .NET Standard 1.5 or higher. Please install 2.0 or higher of the .NET Core SDK.

Breathing new life into a “legacy” ASP.NET website is a way you can help slowly transition the site towards ASP.NET Core. One way you might accomplish that is by referencing .NET Standard libraries. Everything seems fine and dandy until you attempt a publish operation. Generally you might not notice these until running msbuild from command-line–such as in a CI environment, batch deploy script, or otherwise. Let’s talk about one major msbuild error you’ll encounter while publishing your ASP.NET MVC application that references a .NET standard library. We’ll also talk about some other errors that might arise in the process.

Web application stress testing with K6

He's sad because he didn't use k6 for stress testing his web application

When deploying an application to the web performance can be (and usually is) an important factor. Running it on your dev machine isn’t really a good indicator of how well your application will run, however. Finding out how well your application performs before you deploy is a good idea. One way we can accomplish that is by stress testing your web application using a tool called K6.

How I’m clearing my gaming backlog

I’m a gamer. Video games are what initially interested me about computers. DOS prompts, autoexec.bat, config.sys, and a batch loader to reconfigure the system depending on which game I wanted to play was where I first learned how to configure things. Growing older, however, I find that I don’t have the time for my hobby and I fall increasingly behind on my gaming backlog. Exploring the internet I’ve compiled a way that works for clearing my gaming backlog.

Using WCF With .NET Core

Recently I was going through the motions upgrading an ASP.NET Core 2.0 website to 2.2. Overall the process was fairly straightforward, minus some gotchas. We were attempting to switch the website from targeting the full framework (net47) to target netcoreapp2.2 but that caused a cascade of problems. One such problem was WCF. Today we’ll discuss using WCF with .NET Core and some of the gotchas you may run into.

Delayed Cancelable Action Button in React

User experience (UX) is a fine art and many developers fail at it. Years ago I watched a basic UX course on PluralSight by Billy Hollis. Since that time I have tried to focus on UX. One thing I’ve learned over the years is how awful modal confirmations are for delete operations. Today we’ll look at another way to approach delete actions by introducing a delayed cancelable action button in React.

Session management in DotNetCore web applications

Last month we talked about Cookie management in DotNetCore web applications and introduced a generic cookie service. Today we’re going to look at an alternative option for storing user data. Session state is a server store of information linked to a browsing session. Today let’s look at a technique for generic session management in dotnetcore web applications.

Automatically scrolling React component into view upon render

Person using computer presumably writing React

You’ve just finished up your fancy new React component and got it into the workflow. You now perform an action on the page. As a result your component renders but it is under the fold and isn’t visible. You want it to be visible immediately. What can you do? Today let’s talk about automatically scrolling React components into view upon render.

Throttling requests in .NET Core web applications

Last year I worked on a team migrating a large application to ASP.NET Core from ASP.NET MVC 5. Among our goals we wanted to make the site use responsive layout, become “future-proofed” on a technology stack, and clean-up a bunch of legacy cruft. Our initial launch did not go smoothly and we reverted to the previous site to make changes. In the process we learned some “gotchas”. Today I’m going to discuss one of those and how we addressed it. We’ll learn about throttling requests in .NET Core web applications.

Cookie management in DotNetCore web applications

For those of us used to cookies in traditional ASP.NET the switch to ASP.NET Core might leave us scratching our heads. In the old system we were able to directly add and remove cookies from both the request and response objects (for better or worse). This might have led to us writing and overwriting the same cookie multiple times during a request as different portions of code affected it. DotNetCore has changed the game and that’s a good thing, trust me. Today we’re going to learn a technique for cookie management in DotNetCore web applications.
