Steps for setting Jenkins/Bitbucket CI environment in Windows - little trickier than Linux
1) Download and Install Jenkins-2.60.1(current as of the day written)
2) Once installed changed the port from C:\Program Files (x86)\Jenkins\jenkins.xml to ‘9090’ and
restart jenkins
3) Set security options to “false” from config.xml
4) Then open localhost:8090 and see if you can see Jenkins Interface
5) Install all default plugins plus following plugins to work Jenkins correctly with Bitbucket and
dev requirements for my workflow
a. Bitbucket pull request builder plugin
b. Maven integration plugin
c. MS build plugin
d. Next build number plugin
e. NodeJS plugin
f. SSH Agent Plugin
g. SSh plugin
h. Self-organizing swarm plugin
i. Categorized view plugin
j. Publish-over ssh
k. Schedule build
l. Nugget
m. Vagrant
6) Install git bash in the machine
7) From git bash, generate ssh-keys , ssh-keygen
8) Add the public key(id_rsa.pub) in BitBucket under group account

Prevent WPF Global Keyboard Hook from stops working after hitting keys a while C# .NET
The article written by Dylan Currier, Low Level Global Keyboard Hook / Sink in C# .NET is one the simple, easily understandable, and and working post on Global Keyboard hook out there in internet. It worked in my WPF application and I added following line in the WPF app to refresh hook after each key press- IDK if it is write or wrong, more likely to be a wrong practice to hook/unhook every time but it gets the job done. The primary reason to refresh hook is to prevent app hanging (not responding to the key press) after few clicks on the WPF button.
void _listener_OnKeyPressed(object sender, KeyPressedArgs e)
{
_listener.UnHookKeyboard();
_listener.HookKeyboard();
}
Following is the video from Dylan Currier on Low Level Keyboard Hook in C# / .NET"
void _listener_OnKeyPressed(object sender, KeyPressedArgs e)
{
_listener.UnHookKeyboard();
_listener.HookKeyboard();
}

When to use ArcGIS Online to publish geospatial data: CASE STUDY EUROPEAN ENVIRONMENT AGENCY
ArcGIS Online is a workspace and a web platform for creating and sharing maps.
It is possible to upload your data, create a layer or a map, define the extent, set some visualization
options, assign permissions to your layer or map, share, and create web mapping applications or story
maps. For information about the other capabilities please visit http://doc.arcgis.com/en/arcgis-online/.
The ArcGIS online platform is designed to host small datasets, for example demographic datasets. The datasets uploaded to ArcGIS online are relatively small in size, and should not exceed 1-2MB, or around 5000 records. This is to keep the agencies costs down and keep in line with our ArcGIS online pricing plan. It is for this reason that ArcGIS online should not be used to host large datasets, and tiled image services must NOT be uploaded to ArcGIS online. To publish bigger datasets and image services, please refer to the ArcGIS Server.

Catch Exception - Attempted to read or write protected memory in ESRI ArcObjects .Net 4.0 Framework
First - Don't write the code to throw "Attempted to read or write protected memory" ..it is bad.
Second - If you are working on legacy codes and COM objects that throws "Attempted to read or write protected memory" while writing ArcMap add-ins, catch exceptions to prevent application crash, in my case ArcMap.
Step #1 - Add following snippet to config file - app.config for Arc-addin
Add -

Good compatibility of latest vagrant and virtual box
Continuing from my older post on Vagrant 1.7.2 / 1.9.2 and Virtualbox 4.3.12 / 5.1.14. I upgraded into Vagrant 1.9.2 and 5.0.x and 5.1.x , because of security vulnerabilities on those Virtualbox versions, but my shell provisions and puppet provision that used to work on old setting suddenly stopped working and tried various workaround to make them working but failed until Virtualbox 5.1.18. I use chocolaty, to upgrade/install vagrant and virtual box in Windows 7 host and able to fire 'vagrant up' to provision my new guest.
Step 1
Install chocolaty in host machine using cmd.exe (Run elevated)
0.10.3 (as of 3/16/2017)
Step 2
Open Windows' power shell (Run elevated)
1. Install or upgrade oracle virtual box
choco install virtualbox -version 5.1.18
5.1.18 r114002
choco upgrade virtualbox
2. Install or upgrade vagrant
choco install vagrant -version 1.9.2
choco upgrade vagrant
Step 1
Install chocolaty in host machine using cmd.exe (Run elevated)
@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
0.10.3 (as of 3/16/2017)
Step 2
Open Windows' power shell (Run elevated)
1. Install or upgrade oracle virtual box
choco install virtualbox -version 5.1.18
5.1.18 r114002
choco upgrade virtualbox
2. Install or upgrade vagrant
choco install vagrant -version 1.9.2
choco upgrade vagrant
3. Restart the machine
4. Vagrant up ....Boom all old scripts starting work again!

spatial data
· creating GIS
points from XY coordinates (GPS files)
· Sub -setting
data by selection and export
· Creating or
editing GIS data feature by feature
· Buffering small
data layers (few features, simple features)
· Joins on
attribute tables
Not Appropriate for Citrix
· Geoprocessing
(Intersect, Union, Identity …)
· Sub -setting
data by Clipping
· Spatial joins
· Spatial Analyst
· Buffering large
or complex data layers
