Generate  files without installing it
ng new ng2CliApp --skip-install

Create new project with out writing the files in but report them commandline console
ng new ng2CliApp --dry-run

Create new project with app prefix
ng new ng2CliApp --prefix coolapp --dry-run

Create new project without test files
ng new ng2CliApp  --skip-tests --prefix cool_ng2CliApp --dry-run

Create new project with style-sheets
ng new ng2CliApp --skip-tests --prefix cool_ng2CliApp --style scss 

Create new project with Routing
ng new ng2CliApp --routing --skip-tests --prefix cool_ng2CliApp --style scss --skip-install

Solved: Cannot connect Postgre in VM from host

Used vagrant for setting up the VM, so set private network and port forward in vagrant file as below -
               
                 migration.vm.network "private_network", ip: "192.168.33.10"
                 migration.vm.network "forwarded_port",guest:5432 , host:15432 


1. Use telnet localhost 15432 to see if the port is open (Host)


Still can not connect to PostgresSql running in VM  :(

Then

2. Edit postgresql.conf (Guest)
#------------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#------------------------------------------------------------------------------

# - Connection Settings -

           listen_addresses = '*'


3.  Add following in pg_hba.conf

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
host    all              all            0.0.0.0/0               md5


4. Finally, able to connect to Postgres via localhost:15432

Getting started with Raster and PostGIS - I

Steps for loading a raster in PostGIS (PgSql 9.4/ PostGIS 2.2) and pull it from database to view in QGIS 2.14.17.

1. Generate SQL for raster [NOTE: Do not create PostGIS table name starts with underscore, it creates problem while adding raster to QGIS from PostGIS database using DB Manager]

        raster2pgsql -s 4326 -I -C -M -F -t 50x50 -N nan biodiv_ssolnw.tif > biodiv_ssolnw.sql

2. Import generated raster into PostGIS database [Make sure to enable postgis extension in db]

         psql -h localhost -U postgres -d ecolservicedb -f biodiv_ssolnw.sql

the output is:
Processing 1/1: ags_473038164.tif
