Theo's preferred way of handling try/catch in TypeScript
// Types for the result object with discriminated union
type Success<T> = {
data: T;
error: null;
};
type Failure<E> = {
data: null;
error: E;
};

Using MSBuildWorkspace

Introduction

Roslyn provides a rich set of APIs for analyzing C# and Visual Basic source code, but constructing a context in which to perform analysis can be challenging. For simple tasks, creating a Compilation populated with SyntaxTrees, MetadataReferences and a handful of options may suffice. However, if there are multiple projects involved in the analysis, it is more complicated because multiple Compilations need to be created with references between them.

To simplify the construction process. Roslyn provides the Workspace API, which can be used to model solutions, projects and documents. The Workspace API performs all of the heavy lifting needed to parse SyntaxTrees from source code, load MetadataReferences, and construct Compilations and add references between them.

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

  • Stores data elements based on an sequential, most commonly 0 based, index.
  • Based on tuples from set theory.

Use Specific Version of TypeScript with VS Code

NOTE: These steps are only required if you want to use a version of TypeScript that is not the same as the version that is bundled with Visual Studio Code.

  • Install the latest version of TypeScript

    npm install -g typescript@version
    
  • Configure VS Code to use installed version of TypeScript by opening Preferences, User Settings.

Xamarin Reduce App Size
* Reducing executable size:
http://developer.xamarin.com/guides/cross-platform/deployment,_testing,_and_metrics/memory_perf_best_practices/#Reducing_Executable_Size
* Use the linker (iOS [1], Android [2]) to remove unnecessary code from your assemblies
[1] https://developer.xamarin.com/guides/ios/advanced_topics/linker
[2] https://developer.xamarin.com/guides/android/advanced_topics/linking
* Reference third-party libraries judiciously
* Applying constraints to generics may reduce app size, since less code would need to be included (haven’t verified this)
