Intro to MongoDB

I finally was able to write down some of my notes from watching the Pluralsight: Intro to MongoDB course.  These are just my notes but I absolutely recommend you watch the course and signup for Pluralsight.  MSDN subscriptions typically come with some free time with Pluralsight.

Jump start your learning and good luck!


Into to MongoDB
                Server
                Query/Manipulate
                Indexing

No Schema
Single Document write scope - No locking
Eventual Consistency - multiple options
                Fire and Forget
                Majority
                Eventual Consistency
Scalability
                no Schema - Really -> No schema Enforcement


Server Setup
                Open Source (C++)
                Mongod
                                just Create data file/ Run
                mongod --install {installs as service}
                net start MongoDB

MongoDB Shell
                Commands
                                show dbs
                                use foo
                                db -> shows connected db
                                help -> shows all commands
                Like SQL Command prompt
                JavaScript Interrupter
                Can write up your own Editor
                                - Sublime
                                - NotePad ++
                mongorc.js -> always runs

Replica Set
                Primary -> Secondary  & Arbiter (helps to determine who takes over w/ issues)
                Can run all on one Server
                Pro -> Set at least 3 servers

Saving Data
                storing Data
                BSON - Binary JSON

                Rules

                                16 Megabytes per document
                                ObjectID - involves  timestamp in it
                                Insertion is ascending

                db.foo.save({})
                db.foo.insert({}) -> will throw for duplicate key if saving with specific ID

                db.foo.update( query, update, options )

Indexing
                index collection
                usage of indexing

Create your first Windows 10 IoT background app using Visual Studio 2017: Step by step guide

Create your first Windows 10 IoT background app using Visual Studio 2017: Step by step guide Recently, I went as a Sponsor to a .NET Code Camp and one of the raffle prizes we brought was a Raspberry Pi kit.   I was amazed at how many people wanted this device and many of them said they already had them.   They are fairly inexpensive and can be found on a lot of websites.   A few have a lot of capabilities but for this example, you just need a very basic one. I had picked up a Raspberry Pi soon after you could deploy Windows 10 on it and I’ve been slowly playing with it. I thought it would be extremely helpful to show my application logging through a cheap device as well as monitor a process I was running on my server.   Today I’m basically using it as an email generator. I have a process where when my kids create a new gift they want for their B-day, then I have my background process sending an email to everyone in my family members the gift they...

Performance Review Time!

Its  Performance Time ! Over the past 20+ years, I've both gotten performance reviews and given them in many of them too.  As a manager, it’s something you do once per year. Sure, you might do quarterly reviews or semi-annual reviews to make sure associates are on track but everyone cares about the annual review.  They are stressful for both the associate and the manager.  Everyone asks, why I didn't exceed my goals and/or how does this impact my merit increase. Managers have to make extremely tough decision to do what is best both for the organization as well as to meet the budget guidelines we are given. I’d first like to ask the question, do most people even like getting their performance review?  I suspect not.  I’m guessing most would just like to hear the merit increase and move forward. Why? It’s probably because most performance reviews are so poorly given. I admit, I’ve done it myself.  Most performance reviews seem to be rushed. We ...

Unit Test - Given When Then style

Really nice sample I found on the web that Explains the Given-When-Then Syntax style. The Given When Then style correlates closely to the Arrange Act Assert style for unit testing. Here's an example: [Test] public void RotateAngle_Given27Degress_Returns64Degrees() { //Arrange or Given var someAngleClass = new Angle(); //Act or When var result = someAngleClass.Rotate(27); //Assert or Then Assert.That(result, Is.EqualTo(64)); } Thanks:  http://stackoverflow.com/users/445105/joseph
