The GEOADD command allows a user to add geospatial information (item name, longitude, latitude) to a particular key.
The GEOADD command can be used to add a single item to a key:
GEOADD meetup_cities -122.43 37.77 "San Francisco"
or multiple items to a key:
GEOADD meetup_cities -122....
Below give solution can be also use in another supported programming languages with some syntax changes
To do Scroll down page/section/division in webpage while there is custom scroll bar(Not browser scroll). Click Here For demo and check scroll bar has its independent element.

In this example we define a package header and a package body wit a function.
After that we are calling a function from the package that return a return value.
Package header:
CREATE OR REPLACE PACKAGE SkyPkg AS
FUNCTION GetSkyColour(vPlanet IN VARCHAR2)
RETURN VARCHAR2;
...
This examples uses the AES algorithm for encrypting passwords. The salt length can be up to 128 bit.
We are using the SecureRandom class to generate a salt, which is combined with the password to generate a secret key. The classes used are already existing in Android packages javax.crypto and java....
If you want to loop over a list of tuples for example:
collection = [('a', 'b', 'c'), ('x', 'y', 'z'), ('1', '2', '3')]
instead of doing something like this:
for item in collection:
i1 = item[0]
i2 = item[1]
i3 = item[2]
# logic
or something like this:
for item in collec...
Scala packages should follow the Java package naming conventions.
Package names are written in all lower case to avoid conflict with the names of classes or interfaces.
Companies use their reversed Internet domain name to begin their package names—for example,
io.super.math
Import needed libraries:
from gcloud import storage
Define needed variables:
Client: Bundles the configuration needed for API requests
client = storage.Client()
Optional params for Client():
project: the project which the client acts on behalf of. Will be passed when creating a topic. If...
Reading the specification for the document formats in OpenXML can be a time consuming process. Sometimes you just want to see how to produce a certain feature in a word-document.
The Open XML SDK 2.5 Productivity Tool for Microsoft Office (OpenXmlSdkTool.exe) does just that. Its main features are:

To receive messages, use a service that extends FirebaseMessagingService and override the onMessageReceived method.
public class MyFcmListenerService extends FirebaseMessagingService {
/**
* Called when message is received.

Use Enum.chunk/2 to group elements into sub-lists, and Map.new/2 to convert it into a Map:
[1, 2, 3, 4, 5, 6]
|> Enum.chunk(2)
|> Map.new(fn [k, v] -> {k, v} end)
Would give:
%{1 => 2, 3 => 4, 5 => 6}
In OpenCV, images can be RGB/BGR, HSV, grayscaled, black-white and so on. It is crucial to know the data type before dealing with images.
The image data types are mainly CV_8UC3 (Matrix of uchar with 3 channels) and CV_8U (Matrix of uchar with 1 channel), however, the conversion to other types such...
DispatchGroup allows for aggregate synchronization of work. You can
use them to submit multiple different work items and track when they
all complete, even though they might run on different queues. This
behavior can be helpful when progress can’t be made until all of the
specified tasks are c...
Android now supports devices with 512MB of RAM. This documentation is intended to help OEMs optimize and configure Android 4.4 for low-memory devices. Several of these optimizations are generic enough that they can be applied to previous releases as well.
Enable Low Ram Device flag
We are introduc...
The CPU governor itself is just 1 C file, which is located in kernel_source/drivers/cpufreq/, for example: cpufreq_smartass2.c. You are responsible yourself for find the governor (look in an existing kernel repo for your device)
But in order to successfully call and compile this file into your ke...
There are two main functions in Redis (HSET and HMSET) for adding fields to a hash key. Both functions are available in redis-py.
Using HSET:
import redis
r = redis.StrictRedis(host='myserver', port=6379, db=0)
r.hset('my_key', 'field0', 'value0')
Using HMSET:
import redis
r = redis.St...
Redis allows you to add items to either the right or the left of a list.
If I was working with a list, my_list and I wanted to prepend 3 to the list, I could do that using the Redis LPUSH command:
LPUSH my_list 3
If I wanted to append 3 to my_list, I would instead use the RPUSH command:
RPUSH ...
Redis provides the LPOP and RPOP commands as a counterpart to the LPUSH and RPUSH commands for fetching data items.
If I was working with a list my_list that had several data items in it already, I can get the first item in the list using the LPOP command:
LPOP my_list
The result of this comman...
