Graph Theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. Did you know, almost all the problems of planet Earth can be converted into problems of Roads and Cities, and solved? Graph Theory was invented many years ago, even before the in...

Attributes can be useful for denoting metadata on enums. Getting the value of this can be slow, so it is important to cache results. private static Dictionary<object, object> attributeCache = new Dictionary<object, object>(); public static T GetAttribute<T, V>(this V va...

In some cases you may want to change which notification you use based on a tag in the Alert keys. You can do this using the Lookup feature. Note: Lookup only works if you are using OpenTSDB and sending data to the Bosun to be indexed. For other backends or non-indexed data you have to use lookupSeri...

Small, simple csv files can be built using just a text editor, because a CSV file is simply text. If you have spreadsheet software available these are usually an easy way to open and save CSV files. Reading and writing them, or otherwise processing their contents is done more efficiently using the ...

To enable Code First Migrations in entity framework, use the command Enable-Migrations on the Package Manager Console. You need to have a valid DbContext implementation containing your database objects managed by EF. In this example the database context will contain to objects BlogPost and Auth...

After you've enabled migrations (please refer to this example) you are now able to create your first migration containing an initial creation of all database tables, indexes and connections. A migration can be created by using the command Add-Migration <migration-name> This command will c...

Note that the allowDiskUse: true option is optional but will help mitigate out of memory issues as this aggregation can be a memory intensive operation if your collection size is large - so i recommend to always use it. var duplicates = []; db.transactions.aggregate([ { $group: { _id: { c...

One of the most important implementations of Dynamic Programming is finding out the Longest Common Subsequence. Let's define some of the basic terminologies first. Subsequence: A subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the orde...

Before reading this example, it is highly recommended that you read Introduction to Trie first. One of the easiest ways of implementing Trie is using linked list. Node: The nodes will consist of: Variable for End-Mark. Pointer Array to the next Node. The End-Mark variable will simply denot...
