tl;dr Let Visual Studio generate your overrides for Equals() and GetHashCode() so you don’t need to remember the best practices. Don’t roll your own GetHashCode() algorithm or even rely on StackOverflow, use the .net framework to work it out for you.. HashCode.Combine(Long, Lat, Altitude); Background When trying to check the equality of reference objects in c# we simply cannot apply the ‘==’ operator, as this will only compare memory locations and not data.

I’ve never been one to set myself new years resolutions, not for any particular reason, I just don’t. However, last year I set myself several goals and/or challenges.

1. Read 12 books in 12 months
2. 12 blog posts

So how did I go?

SignalR has been around for a few years now (since 2013), offering real-time notifications to our .Net applications.

In an earlier post I described how to leverage the power of RxJS and the combineLatest() and startWith() operators to tidy up my code. I have since updated the code on that page to reflect the new RxJS6 pipe operators.

Out of the box, Angular provides a convenient method for setting environment variables for each our local dev environment and our production environment.

Not long after publishing my recent post on minimising Async bindings in Angular by using the *ngIf=“obs$ | async as obs”; construct, I received the following comment on twitter:

In my [previous post]({{ site.baseurl }}{% post_url 2018-03-26-rxjs-combinelatest-startwith %}) I came across a quirk with Angular, Observables and the Async pipe. That is, each subscription to an observable will initiate the observables execution. Hence we were calling the api once per async subscription. A subscribe call is simply a way to start an “Observable execution” and deliver values or events to an Observer of that execution.http://reactivex.io Original version <p>{{ (result$ | async).

05 June 2018 Update: Follow up post with further refactoring. 01 June 2018 Update: Updated code to RxJS6. Scenario In my Angular5 application I have a search results page that contains three components: Text-based filters component Paged results list Pagination component After wiring up my code I ended up with something similar to below. This all worked fine, but as you can see it’s quite repetitive and not to mention hard to maintain.

It’s time to stop procrastinating… For many years now I’ve spoken on many occasions with colleagues about the importance of keeping a blog, even tonight I interviewed Thiago Passos for SSW TV on his last year or so (still waiting for it to be published), and how he has been working on building his profile, both as a blogger and as a speaker. In closing the interview, I promised Thiago I’d write my first post, and now I’m out of excuses.
