Firestore; add user email identifier without creating a collection

I'm planning to create a web page (lets say for admin) to add user identifier only which is using email and create a temporary password for user without creating a collection.
I'm considering to either use python or java language but I couldn't find any answer whether this can be done or not with cloud firestore. does anyone have any idea?

You can create users for your firebase app without adding them to a collection.
Firestore Admin SDK supports Node.js, Java, Python, Go, C# and .NET it really depends on what language you wish to use for your web server. It could really be either that you choose or you could not use an SDK and instead use something completely different because you can also use firestore with javascript. It really depends on your requirements.
Here is more information on how to set up your environment for which ever option you may need.
To create a user with an email and a password you can use this code in:
javascript
firebase.auth().createUserWithEmailAndPassword(email, password)
.then((userCredential) => {
// Signed in
var user = userCredential.user;
// ...
})
.catch((error) => {
var errorCode = error.code;
var errorMessage = error.message;
// ..
});
Python
user = auth.create_user(
uid='some-uid', email='user#example.com', phone_number='+15555550100')
print('Sucessfully created new user: {0}'.format(user.uid))
Java
CreateRequest request = new CreateRequest()
.setUid("some-uid")
.setEmail("user#example.com")
.setPhoneNumber("+11234567890");
UserRecord userRecord = FirebaseAuth.getInstance().createUser(request); System.out.println("Successfully created new user: " + userRecord.getUid());

Searchanalytics Query JAVA API v3 (Google WebMaster Tools)

I am trying to implement Google Webmasters Searchanalytics Query using using the Java API but i did not found any Java sample to use , in Google website here there is only Python samples for Searchanalytics Query , and they did not say that it's not available in Java API.
I found this class Webmasters.Searchanalytics.Query in the Java API which I assume that is equivalent to the Python function searchanalytics.query() but i did not found any implementation of it.
My question if it is possible to query data from Google Search Console using the Java API??
if yes i wounder if there is someone who can provide a Java sample, something like the Python sample provided by Google here.
Thank you in advance.

I succeded to implement Webmasters.Searchanalytics.Query
as follow
first you need to create your QueryRequest using the SearchAnalyticsQueryRequest class example:
private static SearchAnalyticsQueryRequest createSearchAnalyticsQueryRequest() {
SearchAnalyticsQueryRequest searQueryRequest = new SearchAnalyticsQueryRequest();
searQueryRequest.setStartDate("2016-04-10");
searQueryRequest.setEndDate("2016-04-20");
List<String> dimensions = new ArrayList<String>();
dimensions.add("page");
dimensions.add("query");
dimensions.add("country");
dimensions.add("device");
dimensions.add("date");
searQueryRequest.setDimensions(dimensions);
return searQueryRequest;
}
then executing the query as follow :
public static String Query(String site,
SearchAnalyticsQueryRequest searQueryRequest) throws Exception {
Webmasters.Searchanalytics.Query query = service.searchanalytics()
.query(site, searQueryRequest);
SearchAnalyticsQueryResponse queryResponse = query.execute();
return queryResponse.toPrettyString();
}

I think You missed it. here. Actually all you need to do is to click the Java link on the left.

How to get AWS account details using java api? Not for IAM user

We have two AWS accounts. One is for production and another is for testing. We need to differentiate the environment we are running. We can see that a simple way is to get account name and once we get that it will be very straight forward. But, we don't know how to get it from AWS credentials or properties. Does anyone have idea about how to get account information using AWS credentials?
I considered the possibility of account permissions, account type etc, but I think it should not prevent us from getting account name?

With a rather recent aws java sdk you can use getCallerIdentity:
AWSSecurityTokenServiceClientBuilder.standard().build()
.getCallerIdentity(new GetCallerIdentityRequest()).getAccount()

You can see the GetUserResult. This is returned by getUser(). GetUserResult has a method to get User. This User has all the fields to get the required information you need.

look at the account number that is returned in the get_user (iam user)
eg,
"Arn": "arn:aws:iam::THISISYOURNUMERICACCOUNTNUMBER:user/lcerezo"

AmazonIdentityManagementClient iamClient = new AmazonIdentityManagementClient();
String accountNumber = iamClient.getUser().getUser().getArn().split(":")[4]);

In case you are using the Secured Token Service, you will not be able to get the user details to get the account number. You can instead use the role. Below is the sample code.
AmazonIdentityManagementClient iamClient = new AmazonIdentityManagementClient();
GetRoleRequest getRoleRequest = new GetRoleRequest();
getRoleRequest.setRoleName("roleName");
String accountNumber = iamClient.getRole(getRoleRequest).getRole().getArn().split(":")[4];

Using the AWS v2.0 Java SDK, you can use software.amazon.awssdk.services.sts.StsClient#getCallerIdentity.
First add a dependency to the sts module, eg in gradle:
implementation platform("software.amazon.awssdk:bom:2.14.2")
implementation "software.amazon.awssdk:sts"
Then:
log.info("{}", StsClient.create().getCallerIdentity());
will return:
GetCallerIdentityResponse(UserId=AJAIVBQXMUAJAIVBQXMU, Account=298232720644, Arn=arn:aws:iam::298232720644:user/adrian)

How to install chef extension via azure sdk

I need to create deployment with role that contains Chef extension via Java Azure SDK. I have next code for setting extension parameters, but it doesn't work.
As an example I use next material in Python http://blogs.msdn.com/b/shwetasblogs/archive/2015/02/19/creating-deployment-amp-customizing-linux-vms-with-python-amp-chef-part-2.aspx
private void withExtension(Role role) {
ArrayList<ResourceExtensionReference> references = new ArrayList<ResourceExtensionReference>();
ResourceExtensionReference reference = new ResourceExtensionReference();
reference.setReferenceName("LinuxChefClient");
reference.setVersion("11.*");
reference.setPublisher("Chef.Bootstrap.WindowsAzure");
reference.setName("LinuxChefClient");
ResourceExtensionParameterValue publicConfig = new ResourceExtensionParameterValue();
publicConfig.setType("Public");
publicConfig.setKey("PublicParams");
String value = "{\n" +
" \"client_rb\": \"chef_server_url \\\"https://<chefServerUri>\\\"\\nnode_name \\\"<vmName>\\\"\\nvalidation_key \\\"/etc/chef/validation.pem\\\"\\nlog_location \\\"/etc/chef/client.log\\\"\\nlog_level :info\\njson_attribs \\\"/etc/chef/role.json\\\"\",\n" +
" \"run_list\": [\"role[base]\"]\n" +
"}";
publicConfig.setValue(value);
ResourceExtensionParameterValue privateConfig = new ResourceExtensionParameterValue();
privateConfig.setType("Private");
privateConfig.setKey("PrivateParams");
privateConfig.setValue("{ \"validation_key\": \"" + VALIDATION_PEM + "\" }");
ArrayList<ResourceExtensionParameterValue> parameterValues = new ArrayList<ResourceExtensionParameterValue>();
parameterValues.add(publicConfig);
parameterValues.add(privateConfig);
reference.setResourceExtensionParameterValues(parameterValues);
references.add(reference);
role.setResourceExtensionReferences(references);
}

It seems that you do not encrypt the value of privateConfig and publicConfig. As this official document description(Request body part), before setting value, we need encrypt those values:
<PublicConfiguration>
base-64-encoded-xsd-for-extension-public-configuration
</PublicConfiguration>
<PrivateConfiguration>
base-64-encoded-xsd-for-extension-private-configuration
</PrivateConfiguration>
Please try to add this code into your project:
value=Base64.encode(value.getBytes(Charset.forName("UTF-8")));
By the way, please share more error information if the above code don't work.

I am not able to add the comment, so asking my questions in Reply -
What is the error that you see?
Is your VM getting created successfully?
George, please answer these questions so that I can help you better. By the way, you can check the blog - http://blogs.msdn.com/b/azureossds/archive/2015/09/08/accessing-vm-extensions-like-chef-using-azure-sdk-for-java-programmatically.aspx
for using Azure sdk for Java to access the extensions. You will have to modify the code to set the extension reference in order to create a new one.
Hope this helps !!

How to Set UID with eXist-db 2.2 XMLDB-embedded java API

I am updating an Exist-db XMLDB-embedded application from exist 1.4 to 2.2 using Java 1.8.
The User class has been deprecated in 4.4, so I am using UserAider instead, however the UserAider class does contain the setUID method.
How do I go about assigning a UID to a user?
I am attempting to use the following code to create a user and assign a UID, but the final line is Invalid.
user = new UserAider(username);
user.setPassword(password);
String[] groups = {"user"};
user.setGroups(groups);
user.setUID(-1);
Any help would be greatly appreciated.

UID's are not user modifiable in eXist 2.x. They are auto-assigned and managed by the system
