I had mistakenly save my class as fileName.text file and tried to rename it with fileName .java but the IntelliJ couldn't recognize it and throws the error saying..
After spending long hours on internet, I found a solution and sharing/keeping here for future reference.
Step 1: Click "File"==> "Settings"
Step 2: Expand "Editor" & Click "File Types"
Step 3: You will see all file types on Right. Navigate to the "Text Files" and Click it
Step 4: You should able to see your file name on the bottom of Registered Patterns (lower box)
Step 5: Remove your file from the Registered Patterns. The problem should solved and let you to rename with fileName.java
Step 6: If not, delete the file from the project and create it again with name fileName

String baseFont = position.getFont().getBaseFont();
if (baseFont != null && !baseFont.equals(prevBaseFont))
{
builder.append('[').append(baseFont).append(']');

Tips to share a leaflet map with multiple ROIs
Do you have a Leaflet map? Yes. Can you panned and and
zoomed to a particular event or ROI in the map? Yes. Then, how can you share
that map zoomed or centered with ROI/events to your webpage or email as a link? One of the
answers may be set the zoom level and set view near the ROI. Alright, what will you do if you have a map
with multiple ROI/events? Do you make multiple maps with multiple zoom level
and view? You can, but probably not a good idea to do that.
The solution comes here, leaflet-hash.js, solves your needs, it is a JavaScript library
written by Michael Lawrence Evans, which appends the URL hashes to web pages
automatically and the hash changes with Leaflet map on drag or zoom. The hash
consists of map zoom level and latitude/longitude of the center of map
viewport, everything you need to share the map with focused ROI as link in
following simple steps:

How to display the MesoWest weather stations in Leaflet.js?
Snippet to display MesoWest weather stations in Leaflet.
//Hold markers group
var mesoMarkersGroup=new L.LayerGroup();
//Get weather information from Mesowest for the state VA
$.getJSON('http://api.mesowest.net/stations?callback=?',
{
state:'va',
latestobs:1,
token:'demoToken'
},
function (data)
{ //Loop through all the weather stations
for(var i=0;i<data.STATION.length;i++)
{
try{
var stn = data.STATION[i];
var dat = stn.OBSERVATIONS;
var stnInfo =stn.NAME.toUpperCase();
var elev=parseInt(stn.ELEVATION);
stnInfo = "<b>Air Temp: </b>"+Math.round(dat.air_temp[1])+"°F"+ "</br><b>Wind Speed: </b>"+Math.round(dat.wind_speed[1]* 1.150)+"MPH"+"</br>
+<b>Wind Direction: </b>"+getCardinalDirection(Math.round(dat.wind_direction[1]))+"</br><b>Relative Humidity: </b>"+dat.relative_humidity[1]+"%"+"</br>
+<b>Elevation: </b>"+elev+"′";
//Add stations into Leaflet markers group
L.marker(L.latLng(stn.LATITUDE,stn.LONGITUDE),{title:stn.NAME.toUpperCase()}).bindPopup(stnInfo).addTo(mesoMarkersGroup);
}
catch(e)
{
alert("Error! "+ e);
}
}
})
.done(function()
{
})
.fail(function()
{
alert("Could not access the MesoWest!");
});
//Add markers group to the Map
map.addLayer(mesoMarkersGroup);
Where are my streets Chrome? Google Maps bug on Chrome or vice-versa
I was checking the route for nearest police station from my office around 3 PM MT using the Chrome. The Google Map's street looks so funny and floppy. All the street lines and highways lines were wiped out. The interstate has some brown points, if you zoom in them the point looks like half circle. Which has the bug Google Maps or Chrome? Click on images for bigger picture !
(Missing roads on zoom)
(More zoom in...)
(Missing roads)

(Looks good in the Firefox though)

National Geodetic Survey plans to release future Geodetic Datums in 2022
National Geodetic Survey (NGS) developed videos to give you a better understanding of NGS' plans to release new datums in 2022. If you use mapping products or other geo-spatial tools, these videos should also help you find out how you can prepare for the new datums. . It’s a number of years off - but the links explain the changes and provide some initial knowledge that may help you prepare for their advent…
This series of short videos, produced in collaboration between NOAA's National Geodetic Survey and The COMET Program, a part of UCAR's Community Programs, provides an introduction to geodetic datums for anyone who uses mapping products or other geo-spatial tools.
In the first video, "What are Geodetic Datums?" (4:36), explains the basic concepts behind geodetic datums, where they are used, and why it is important to know about and use the correct datums.

Leaflet TypeError: t is null
There are may be several reasons for TypeError:t is null, but I solved my problem by changing-
L.marker(LATITUDE,LONGITUDE).bindPopup("Info").addTo(map);
to
L.marker(L.latLng(LATITUDE,LONGITUDE)).bindPopup("Info").addTo(map);
