Self-Sovereign Verifiable PayID
draft-aanchal-self-sov-verifiable-payid-protocol
This specification defines one of the extensions of the Basic PayID protocol [PAYID-PROTOCOL] that aims to enable trust-minimized PayID service. Specifically, this extension of Basic PayID protocol eliminates the trust requirement between the PayID owner and their PayID service provider by allowing PayID server operators (such as wallets/exchanges) to send payment account(s) address information associated with a PayID [PAYID-URI] that is digitally signed with the PayID private key of the PayID owner along with PayID owner's identity information and other meta-data needed to verify the signature. As a result, Self-Sovereign Verifiable PayID enables PayID service providers to match the security model of applications such as non-custodial digital wallets.
This specification is a draft proposal, and is part of the PayID Protocol initiative. Feedback related to this document should be sent in the form of a Github issue at: https://github.com/payid-org/rfcs/issues.

This protocol can be referred to as Self-Sovereign Verifiable PayID. It uses the following terminology.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119] and [RFC9174][].
While Self-Sovereign Verifiable PayID can be used in any context, its most immediate use case is to enable non-custodial service providers to provide hosted PayID service while preserving the existing trust assumptions between themselves and their users.
Providers of PayID-enabled payment services can be broadly categorized as custodial and non-custodial, each of which operate under different security models. Non-custodial wallets/exchanges do not store their customers’ on-ledger private keys on their servers. Instead, these customers hold their private keys and hence are in full control of their funds. As such, there is no trust requirement between non-custodial wallets/exchanges and their customers, and these services are not responsible for any for lost, compromised or stolen private keys of their customers. Likewise, customers of non-custodial wallets/exchanges do not need to worry if the servers of those wallets/exchanges are compromised.
Basic PayID protocol [PAYID-PROTOCOL] specifies a protocol to interact with a PayID server and retrieve a payment account(s) address information resource along with other meta-data corresponding to the queried PayID. One of the security assumptions made by the basic PayID protocol that may be less desirable for some applications is that the owner of the PayID must trust their PayID server to provide correct and untampered responses. Under this model, the PayID server has full control over the contents of any PayID response message, with potentially adverse effects if the server goes rogue or is compromised. The PayID owner has no way of knowing if the PayID server behaves maliciously. This implicit trust assumption between the PayID owner and their PayID server is often unacceptable in a non-custodial setting.
Self-Sovereign Verifiable PayID protocol allows a PayID owner to digitally sign a PayID response using a local application/device with their PayID private key (which never leaves their device). This signed PayID response can then be securely transferred to the non-custodial PayID service provider's server who can then send this as a response to a PayID query along with PayID owner's "identity" information. PayID clients can use this information to verify if a PayID response is signed by the PayID owner and then decide whether to proceed with any particular transaction. Consequently, the trust between a PayID owner and their PayID server to serve the correct mappings is removed.
The Self-Sovereign Verifiable PayID protocol is designed along the same design principles as [PAYID-PROTOCOL].
The PayID Protocol [PAYID-PROTOCOL] defines a Payment Account(s) Information Resource that contains information about a particular PayID. This document further refines this definition to allow this information to be digitally signed, and then represented as a JSON Web Signature (JWS) [RFC7515] using JWS JSON Serialization.
Below, this document further defines the structure of each JWS component, for the purposes of Self-Sovereign Verifiable PayID protocol.
For JWS, the members of the JSON object represented by the JOSE Header describe the cryptographic operations applied to the JWS Protected header and the JWS payload and optionally additional properties of the JWS.
For a complete list of members of this object, refer to [RFC7515]. Following is a decoded JSON payload representing an example of JOSE protected header parameters as defined by the JWS JSON Serialization syntax.
{ "name": "identityKey", "alg" : "ES256K", "typ" : "JOSE+JSON", "b64" : false, "crit": ["b64"], "jwk" : { "kty": "EC", "use": "sig", "crv": "secp256k1", "x" : "0", "y" : "0", }, }
The name Header Parameter identifies the type of signature. It is a new OPTIONAL header parameter that is not defined in the IANA JSON Web Signature and Encryption Header Parameters Registry.
The alg (algorithm) Header Parameter identifies the cryptographic algorithm used to secure the JWS. This is a required field as described in [RFC7515]. We RECOMMEND using "ES256K" which is Elliptic Curve Digital Signature Algorithm (ECDSA) using secp256k1 curve-type and SHA-256 hash-type as defined in IANA JSON Web Signature and Encryption Header Parameters Registry.
The typ (type) Header Parameter is used by JWS applications to declare the media type of the complete JWS as described in [RFC7515]. If used, the value of typ field SHOULD be set to "JOSE+JSON".
The b64 (base64url-encode) Header Parameter is an extension to JWS specification that determines how a payload is represented in the JWS and the JWS signing input. When the "b64" value is false, the payload is represented simply as the JWS Payload value with no encoding; otherwise, it is represented as ASCII(BASE64URL(JWS Payload)). This is an optional field as described in [RFC7797].
The crit (critical) Header Parameter indicates that extensions to JWS specification are being used that MUST be understood and processed. This is a required field to be used with "b64" parameter as described in [RFC7797].
The jwk (JSON Web Key) Header Parameter represents the public key that is used to digitally sign the JOSE header and JWS payload. This parameter is represented as a JSON Web Key as specified in [RFC7517]. In the header above, members of "jwk" represent the properties of the public key, including its value that corresponds to the algorithm "ES256K".
Note: "jwk" is one way way of embedding public key in the JOSE header. For more details on other possible options for "alg" and representing public keys refer to [RFC7515].
The JWS payload is the message that needs to be signed.
{ "exp" :<PHONE_NUMBER>, "payId": "bob$wallet.com", "payIdAddress": { "expTime":<PHONE_NUMBER>5, "paymentNetwork": "XRPL", "environment": "TESTNET", "addressDetailsType": "CryptoAddressDetails", "addressDetails": { "address": "rnzBSt9ZCJSh4RxC9f1v6oS9WZtEYJa8B9", "tag": "12345" } } }
The exp field is an optional field as described in [RFC7519]. If used, it SHOULD be set to the expiration time of the cryptographic key used to generate the digital signature.
The payId field is a required field. The value of payId field is the PayID URI in the client request that identifies the payment account information that the JSON object describes.
The PayIDAddress is a required field. The value of PayIDAddress field is a JSON object with the following keys:
The address field MUST be present in the JWS payload.
The JWS signature is the digital signature which is calculated over the JOSE header and the JWS payload.
"signature": "{base64Signature}"
The value of signature is computed as described in [RFC7515].
A pre-requisite for this protocol requires the PayID owner to transfer signed PaymentInformation to the PayID server. This document specifies one such way of doing this.
The following are the pre-steps that a PayID owner's device should perform locally:
We RECOMMEND using elliptic curve (EC) key type with Elliptic Curve Digital Signature Algorithm (ECDSA) with secp256k1 curve for creating JWS content.
For each payment-network and environment that the PayID owner has a payment address for, generate the JOSE header, JWS Payload and JWS Signature as described above. A complete PaymentInformation response might look like:
{
"payId": "bob$wallet.com", "addresses": [], "verifiedAddresses": [ { "signatures": [ { "protected": { "name": "identityKey", "alg": "ES256K", "typ": "JOSE+JSON", "b64": "false", "crit": ["b64"], "jwk": { "kty": "EC", "use": "sig", "crv": "secp256k1", "x": "b8w36l6eCf7GyD5fvXp0Xj7ugdFuvYYcnmb1VRjBl5g=", "y": "Tp8RPAf4dWkd+K/BApSW/Ey5UJs53NOPJRqDNZzItPc=", }, }, "signature": "{base64Signature}", } ] "payload": { "exp" :<PHONE_NUMBER>5, "payId": "bob$wallet.com", "payIdAddress": { "expTime": "paymentNetwork": "XRPL", "environment": "TESTNET", "addressDetailsType": "CryptoAddressDetails", "addressDetails": { "address": "rnzBSt9ZCJSh4RxC9f1v6oS9WZtEYJa8B9", "tag": "12345" } } } } ] }
Implementations SHOULD use a secure communication channel to transfer these resources to the PayID server.
Following are the basic operations performed by a Self-Sovereign Verifiable PayID client and server to retrieve PaymentInformation resource corresponding to a PayID.
When requesting the PaymentInformation resource, a Self-Sovereign Verifiable PayID client MAY use the same HTTP GET method as in [PAYID-PROTOCOL] to the PayID URL without any query parameters and body.
The PayID client MUST query the PayID server using HTTPS only. [RFC2818] defines how HTTPS verifies the PayID server's identity. If the HTTPS connection cannot be established for any reason, then the PayID client MUST accept that the PayID request has failed and MUST NOT attempt to reissue the PayID request using HTTP over a non-secure connection.
Upon receiving a GET request for a payment accounts(s) information resource or a PaymentInformation resource, a PayID server that supports Self-Sovereign Verifiable PayID protocol returns the PaymentInformation resource for the payment-network and environment requested by the PayID client in the request Accept header field, along with other required and/or optional metadata.
However, if the PayID server does not support the Self-Sovereign Verifiable PayID protocol, the PayID server sends back a response as described in [PAYID-PROTOCOL].
If the PayID server does not contain the payment accounts(s) information resource or a PaymentInformation resource resource corresponding to the request, the PayID server MUST respond with an appropriate error message.
The PayID client MUST conform to the verification of JWS as specified in [RFC7515].
This section shows sample use of this extension of Basic PayID protocol in a hypothetical scenario.
Suppose Alice wishes to send a friend some XRP from a web-based wallet provider that Alice has an account on. Alice would log-in to the wallet provider and enter Bob's PayID (say, bob$wallet.com) into the wallet UI to start the payment. The Wallet application would first discover the PayID URL for the PayID service-provider using one of the mechanisms described in PayID discovery [PAYID-DISCOVERY] protocol.
The Wallet application would then issue an HTTPS GET request:
GET /users/bob HTTP/1.1 Host: www.wallet.com Accept: application/xrpl-testnet+json PayID-version: 1.0
Bob's wallet (e.g., a non-custodial wallet operating a PayID server) might respond like this:
HTTP/1.1 200 OK Content-Type: application/json Content-Length: 403 PayID-Version: 1.0 Cache-Control: "no-store" Server: Apache/1.3.11 { "payId": "bob$wallet.com", "addresses": [], "verifiedAddresses": [ { "signatures": [ { "protected": { "name": "identityKey", "alg": "ES256K", "typ": "JOSE+JSON", "b64": "false", "crit": ["b64"], "jwk": { "kty": "EC", "use": "sig", "crv": "secp256k1", "x": "b8w36l6eCf7GyD5fvXp0Xj7ugdFuvYYcnmb1VRjBl5g=", "y": "Tp8RPAf4dWkd+K/BApSW/Ey5UJs53NOPJRqDNZzItPc=", }, }, "signature": "base64Signature", } ] "payload": { "exp" :<PHONE_NUMBER>, "payId": "bob$wallet.com", "payIdAddress": { "expTime":<PHONE_NUMBER>5, "paymentNetwork": "XRPL", "environment": "TESTNET", "addressDetailsType": "CryptoAddressDetails", "addressDetails": { "address": "T7CKYKhRujaxEs9fSxQwJApHsQVPKUgD7EtLWCGTAFBwTha" } } } } ] }
In the above example, the PaymentInformation resource is a pre-signed message with the PayID private keys of the PayID owner Bob. Bob's non-custodial wallet retrieves this response and sends it to the PayID client.
This security considerations section only considers PayID clients and servers bound to implementations as defined in this document.
The security guarantees mentioned in [PAYID-PROTOCOL] apply to this protocol. In this section, we discuss the security model for Self-Sovereign Verifiable PayID protocol for non-custodial service providers.
In the current security model, non-custodial wallets do not store their customers’ keys. Instead, wallet customers hold their private keys on their own device(s). There is a no trust requirement between the service provided by a non-custodial wallets and its customers. Because customers in this scenario hold the private keys: * Wallets are not liable for any consequences coming from the loss, compromise or theft of customers' private keys. * The non-custodial wallets do not require their customers to trust their servers in case wallets servers go malicious or are compromised.
This extension of Basic PayID protocol preserves this trust model. Rather than requiring the PayID server to provide accurate PayID response for their customers, the PayID owners can generate these signed mappings with their own PayID private key locally on their app/device. The sender of the payment (PayID client wallet’s customer) can easily verify these signatures out-of-band with the receiver (i.e., PayID owner). This eliminates any risk of the non-custodial PayID server wallet losing its private keys, going malicious, getting hacked, or becoming otherwise compromised in a way that customers might lose funds.
The implementations of this extension of Basic PayID protocol MUST refer to the Security Considerations sections of [RFC7515] and [RFC7519].
The addresses array in the PayID response is an array of unsigned payment addresses. Implementations of this extension of Basic PayID that choose to populate this array along with the verifiedAddresses array MAY be vulnerable to downgrade attacks. We RECOMMEND against populating this array unless absolutely necessary depending on the use-case. Also, note that this approach is not backwards-compatible with the PayID clients that do not understand Self-Sovereign Verifiable PayID protocol.
All privacy guarantees in the Privacy Considerations section of [PAYID-PROTOCOL] apply to this extension of Basic PayID protocol.

React
## Let's do some backend development! We are going to look at Drupal blocks and how to manage them. Then we are going to create a custom module that adds our own custom block. ### Agenda 1. What are Blocks? 2. Managing Blocks 3. Create a Custom Module 4. Create a Block Plugin 5. Parts of a Module Explained --- ## What's a Block? A block is a box of content that we can place into any area of a page, such as the sidebar region, the header, or the footer. A block can stay in place while the main content of the page changes, and you can control which pages it displays on and who sees it.
The default Drupal configuration comes with two blocks enabled, which you can see in the sidebar: `Search` and `Tools`. Let’s change the way those blocks are positioned. --- ## Managing Blocks ### Exercise 1. In the Admin UI, go to `Structure > Block layout`. Can you find the `Search` and `Tools` blocks? 2. Try putting one of them in a different region. 3. Save blocks at the bottom of the screen and look at the front page again.
What has changed?
You can see that not only the position of the blocks but the way they look changes depending on which region they appear in. Their appearance is controlled by the CSS in your `theme` (we'll get to that later). The `regions` you see on the Block page are defined in your theme. When you create a custom theme, you can define the regions any way you want. In addition to the standard blocks that come with core Drupal, we can create our own custom blocks. To do this, we need to create a `custom module`. --- ## Create a Custom Module Creating custom modules, themes and plugins (like blocks) has gotten very easy since the introduction of Drupal Console. With Drupal console, you can create a basic version of any of many common Drupal elements very easily from the command line. Let’s give it a try! ### Using Drupal Console Open your terminal and navigate to your project folder. If you type `drupal` in the command line, you should see a list of all drupal console commands.
Which one do you think you should use to generate a module? Hint: there are descriptions next to the commands. You will use `drupal` followed by the correct command to begin the process. --- ## Using Drupal Console Follow the steps to generate your module. You can call it anything you like. A typical naming convention is to use the name of the larger project followed by the main function of the module. For a module for this project that contains various functionality, you might call it `Fellowship Core`. Here is an example: ```JS drupal generate:module --module="Fellowship Core" // Displays on Extend page --machine-name="fellowship_core" // Only letters and underscores. You will use the machine name later to specify the module for the block --module-path="/modules/custom" --description="Core functionality for Fellowship" // Displays on Extend page --core="8.x" --package="Custom" // Groups similar modules on Extend page --module-file=”yes” // Provides hook_help by default --composer=”no” // You can use a composer file to download dependencies, but we don’t need to do that for this exercise --twigtemplate=”no” ``` Now take a look in your project files. You should see a folder under `/modules/custom` with your custom module in it. Navigate to `Extend` in the Admin UI and type the name of your module in the search field. You should see your custom module in the list of modules. Enable it. Your custom module now exists, but it doesn’t do anything yet. We need to add some functionality to it.
Let’s add a custom block.
--- ## Create a Block Plugin A block in Drupal is a type of `Plugin`. ### What’s a Plugin? A `Plugin` is a reusable piece of code. It can be used in various places in a Drupal project. Plugins are generally represented somehow in the Admin UI as an item that can be manipulated: a widget, a block, a field, etc. Type `drupal` again in your terminal in the root of your project. You should see a list of available Drupal Console commands.
Do you see a command that will generate a block plugin?
--- ## Generate the Block Go ahead and generate the block. Let’s make it a Welcome block that will display a welcome message. Here is an example (feel free to customize it): ```JS drupal generate:plugin:block --module="fellowship_core" // The machine name of our custom module --class="WelcomeBlock" --label="Welcome block" // You’ll see this label in the Admin UI. --plugin-id="welcome_block" --theme-region=[] // Just leave this empty for now, we’ll choose the region in the Admin UI. --inputs=”no” ``` The `generate block` dialogue includes an option to create a form for your block, that lets you enter the content of the block in the Admin UI. But we are going to skip that for now in order to keep it simple. Let’s take a look at our module! --- ## Customize the Block You'll see a new directory in our module, the `/src` directory. It contains the block plugin in `/src/Plugin/Block/WelcomeBlock.php` Open the `WelcomeBlock.php` file. It contains just one function, which is `build()`. To customize this block to display our own custom message, we need to modify the build array in the `build()` function. Try this (feel free to customize with your own message): ```PHP public function build() { $build = []; $build['welcome_block']['#markup'] = 'Welcome to Fellowship, yo!'; return $build; } ``` ### Place the block In the Admin UI, go to `Structure > Block layout`. Choose a region and place your block in it. Take a look at your front page. You should feel very welcomed now. That feels good.
Congrats on completing your first backend Drupal task. Now, let's theme the block!
--- ## The parts of a module, explained It is very nice that we have Drupal Console to help us create modules. We used to have to create them from scratch. But as a developer, you will do work on every part of a module, so it is important that you know the module structure inside-out. ### .info.yml The info file tells Drupal about our module. - The Name and Description appear on the Extend page - Package provides grouping on the Extend page - Core version tells Drupal that it is a Drupal 8 module - Type allows composer to install the module in the correct location ### .module This file contains any Drupal hooks that you add. Hooks are triggered by many different Drupal events. Adding a hook means that the code you add in the hook will be triggered when the Drupal event occurs. Common examples would be after a node is saved, or before a view renders on a page. Drupal generate adds hook_help to the .module file by default. Hook help provides an entry on the Help page. You can customize your entry however you wish. --- ## Classes and Object-oriented Programming in Drupal Let's take another look at your Welcome Block plugin. There are several important things to learn about this file. A `plugin` is a `class` that acts in a specific way. In `object-oriented programming (OOP)`: - classes are a template for an object - In the case of a block plugin, the object will be a block - In this class, we are defining how our block is constructed. ### Extending Drupal base classes In Drupal, there are generic classes for common elements like blocks, forms, and widgets. When we create custom versions of these elements, we `extend` base classes and create a custom version of them. Our custom version inherits all of the functionality of the base class and we can override and add more functionality as needed. Take a look at line 15 in your WelcomeBlock.php file: - `WelcomeBlock` is the name of your class - It extends `BlockBase` - `BlockBase` is the generic class for a Drupal block and contains functionality that we can override and extend. In our case, all we want to do is override the build() method. Plugin classes are discovered by Drupal using their `annotation`. Look above your class name. The area from line 7 – 14 is `annotation`. You define the ID of your plugin here. The admin label will be displayed in the Admin UI. Once Drupal has discovered your class using this annotation, it will be available in the Admin UI. ### Namespacing All classes in Drupal need a namespace. The namespace is part of the identity of the class, and is the way you can use the class in other areas of the code. Look at the namespace of our class on line 3. It starts with Drupal, then uses the name of our module, then the path within the /src file. Notice that /src is not included in the path. This is because all class files are assumed to be located in the /src directory. --- ## Module Standards ### Organizing your Classes The structure follows a convention for organizing class files in Drupal. - All class files go in the /src folder - Within the /src folder, there is an organizational convention that you should follow, that all Drupal modules follow so that you can easily find classes in them - Plugins should go in a /src/Plugin directory - Blocks are a type of Plugin that can go in its own subdirectory, /src/Plugin/Block The advantages of this type of organization become clear if you look at a module that has many classes in it. ### Naming Conventions and Cases Note that in Drupal, there are several different types of case that you can use to name files, functions, and classes. Follow the example provided by Drupal Console. You can always also look at Drupal core files for code examples. The cases are as follows: - camelCase (first word is not capitalized, often used for function names) - PascalCase (first word is capitalized, used often for class names) - snake_case (all lowercase, words separated by underscore, often used for module names and plugin IDs) It is important to have clean, well-organized and well-documented code! Your teammates and your future self will thank you. When you have time, it is worthwhile to take a read through the [Drupal Coding Standards] (https://www.drupal.org/docs/develop/standards/coding-standards). ---

Confluent has created a JMS Client for that comes handy when working with legacy systems. Notably, it wraps a JMS 1.1 implementation and data flow goes like this:
[kafka-jms-client] <--- kafka protocol ---> [kafka broker]
It is important to note that compatibility with JMS 1.1 is pretty good but not complete. Preferably, read https://docs.confluent.io/current/clients/kafka-jms-client/.
We are going to configure and run it against Confluent’s Cloud. The code can be downloaded at: https://github.com/emmanuel-galindo/kafka-jms-client
As part of this exercise, we are going to create a producer that will create one message, and a consumer that if it is the first (from the consumer group) will download all message in the topic, if not will just use whatever offset the broker has. These clients are meant to be as much JMS compliant as possible, thus no use of specific logic, and the idea was to keep it simple.
As a side note, I’ve found this exercise useful before jumping into trying to make legacy systems JMS implementation connect and interact with a topic in Confluent’s Cloud. In addition to the challenge of configuring the JMS service in the legacy system, as Kafka basically works on Layer 4 (https://en.wikipedia.org/wiki/OSI_model), you could expect your company’s proxy, firewall, vpn, etc to give you some trouble and executing this exercise could help you identifying what are the constraints in your network.
Requirements
If you haven’t already go ahead and create a free cloud account. You’ll need to create a new topic (we are using TestTopic as name) and get some information to configure the client: - At API Access menu, issue an API Key and Secret to be used as username and password - In the Tools and client section - In Clients tab, at Java section, copy the properties - In Confluent Platform Components, at Schema Registry, create a new API Key and Secret
Then, you’ll need to compile Confluent’s Kafka JMS Client following https://docs.confluent.io/current/clients/kafka-jms-client/installation.html#appendix-1-creating-a-shaded-fat-jar. As it is mentioned there, to avoid namespace conflicts, it adds the confluent.shaded. preffix. We’ll see this when configuring the login class.
After that, go ahead and grab a jar for the JMS 1.1. I’d normally refer to Maven central, but it looks there’s some legal battle around this. I’ve found https://repository.jboss.org/maven2/javax/jms/jms/1.1/ to have a working copy.
Installation
Create a new working dir, or clone the repo above, and create a new lib/ folder. In there, copy the two jar files.
Producer
Create a Producer.java file and copy below code in it. As you can see, it is a pretty standard JMS implementation. I am importing here using wildcard to make it short.
import javax.jmx.*;
import javax.naming.*;
public class Producer {
public static void main(String[] args) throws JMSException, NamingException {
Context ctx = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory)ctx.lookup("ConnectionFactory");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = (Queue)ctx.lookup("TestTopic");
MessageProducer producer = session.createProducer(queue);
TextMessage message = session.createTextMessage();
message.setText(new Date().toString() + " - Text message");
producer.send(message);
}
}
Consumer
In this case, a Consumer.java needs to be created with this content.
import javax.jmx.*;
import javax.naming.*;
public class Consumer {
public static void main(String[] args) throws JMSException, NamingException {
Context ctx = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory)ctx.lookup("ConnectionFactory");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = (Queue)ctx.lookup("TestTopic");
MessageConsumer consumer = session.createConsumer(queue);
while(true) {
TextMessage rmessage = (TextMessage) consumer.receive();
System.out.println("Message received " + rmessage.getText());
}
}
}
jndi.properties
Create a new file jndi.properties at the same folder as the consumer and producer. Here is where the specifics for Kafka and Confluent Cloud are set:
#Kafka Cloud settings
bootstrap.servers = your_cloud_server.confluent.cloud:9092
security.protocol = SASL_SSL
#Calling the shaded version of the fat jar. Remove confluent.shaded when calling the thin jar
sasl.jaas.config = confluent.shaded.org.apache.kafka.common.security.plain.PlainLoginModule required username="USERNAME123" password="PASSWORD123";
ssl.endpoint.identification.algorithm = https
sasl.mechanism = PLAIN
# when there's no offset for this consumer, lets show a lot =)
auto.offset.reset = earliest
consumer.group.id = jms-client-test
queue.TestTopic = TestTopic
# Cloud Schema Registry settings
basic.auth.credentials.source = USER_INFO
schema.registry.basic.auth.user.info = USER345:PASSWORD345
schema.registry.url = https://your_cloud_registry.confluent.cloud
# JMS settings
java.naming.provider.url = tcp://your_cloud_server.confluent.cloud:9092
java.naming.factory.initial = io.confluent.kafka.jms.KafkaInitialContextFactory
client.id = jms-client-test-id
#register topics in JNDI. format: [topic|queue].[name] = [name]
- bootstrap.servers and java.naming.provider.url has the same value
- modify the USERNAME123 and PASSWORD123 with the API key and secret from Confluent Cloud
- auto.offset.reset is an example of a kafka property extended to this JMS client.
- consumer.group.id. If you implement this as we did above, we are letting the JMS client library know we want to use queues. In that case, the consumer group in the broker will be set to that value. As stated in the docs, if we were using topics, the lib would add a uuid to the end of the topic name and each consumer seems to end up having a sepparate consumer group. This is a very nice way to emulate what you normally experience with topics and queues in JMS.
- queue.TestTopic, defines what is the kafka topic we are going to work with. In Kafka, both JMS topics and queues are implemented as Kafka topics and I believe the intention of this library is try to emulate a normal JMS behavior. If we would like to do JMS pub/sub, we would then change the implementation at the code to use JMS Topic and here we would call this property topic.TestTopic
- I haven’t tested extensively the schema registry, so please free to share what you find
Executing
We are using standalone java here. In Linux you would execute this:
$ javac -cp lib/*:. Consumer.java
$ java -cp lib/*:. Consumer
In Windows
$ javac -cp "lib/*;." Consumer.java
$ java -cp "lib/*;." Consumer
And the same for the Producer.
First execute the producer, and then the consumer. You can leave the consumer, or start a new one in another shell session. The producer will just send one message and you can ctrl+c after that.
When executing the clients you should expect below output (it might take one minute or two to spin up the client and connect to the broker, feel free to add some print lines):
Producer:
Message sent
Consumer:
Message received Tue Aug 11 19:12:49 ART 2020 - Text message
A nice test, is to shutdown the consumer, send another email and as you would expect from queues, when you spin up the consumer again you should receive the message.
Another interesting one, is to modify the consumer group to a new one and it shoud download all messages.

Presentation API Tutorial
The Presentation API allows a web app to present web content on a secondary display connected to the device. It has several uses: presenting slides, sharing video and image, and playing game on a large screen TV via the mobile device.
Presentation API is an experimental feature for Crosswalk for Android 4.2+ based on Miracast-compatible wireless display support. It is available in current versions of Crosswalk. This tutorial is based on an article from HTML5 Hub by Hongbo Min, and has been tested with Crosswalk Stable 11.40.277.7.
The Presentation API is defined as follows:
interface Presentation :EventTarget {
void requestShow(DOMString url, successCallback, errorCallback);
readonly attribute boolean displayAvailable;
attributeEventHandler ondisplayavailablechange;
};
In Crosswalk, the Presentation API is exposed as an additional property to the navigator object:
navigator.presentation.requestShow
navigator.presentation.displayAvailable
navigator.presentation.displayavailablechange
Note: the Presentation API W3C spec is still evolving, and may be modified to meet new usage scenarios, such as integration with Chromecast devices.
Setup Wireless Display
Requirements
- Android 4.2 or newer device with Miracast protocol support.
- A TV or display with an HDMI port.
- A Miracast certified wireless display adapter, for example the Netgear PTV3000 (tested)
- Plug the wireless display adapter into the display’s HDMI port.
- On the Android device, open the ‘Settings’ app and select the ‘Display’ entry.
- Turn on ‘Wireless display’ to connect to the available wireless display.
Alertnative: no wireless display
If you do not have a wireless display adapter but are willing to run the application on your device, Android gives you the option to use a simulated secondary display for testing purposes. This simulated display appears as an overlay on your device screen. To enable it:
- Open the
Settings
app and selectDeveloper Options
. - Use the
Simulate Secondary Display
option to select a display to simulate.
Sample Code
In the following sample, there are two HTML files:
index.html
– a controller page which shows on the primary display and opens a page on the secondary displaycontent.html
– the content page to show on the secondary display
index.html
<!DOCTYPE html>

<input type="button" onclick="showPresentation();" value=”Show Presentation”>
</input>

Error: No message from primary display

content.html

Message from its opener:

Error: No message received from secondary dispaly

Follow the instructions on how to build a Crosswalk application to package the above two HTML files into an Android application; then follow the instructions for running on Android to launch the application on a Android 4.2+ device. Make sure there is at least one available secondary display before running the application: see the Setup Wireless Display section above.
Once the application is running, clicking the “Show Presentation” button will open the content.html
page on the secondary display.
You should see the following output on the primary display:
Hello from the secondary display
and this output on the secondary display:
Hello from the primary display
If there is no available wireless display, you will get an alert dialog with the message “No available display found”.
For an example of a more realistic HTML5 app using a secondary display, check out the ImageGallery demo. This demonstrates how to use the Presentation API to view photos on a wireless display.
Details of the JavaScript API
presentation.requestShow Method
requestShow
sends a request to the user agent to show a presentation. If a secondary display is ready for use, a new presentation window for the HTML page specified by the url will be opened on the secondary display. This secondary window is opened from the current browsing context. Once the page has finished loading, the successCallback
method is invoked with the window object of the new page as the input parameter. Thus, the communication between the opener window and presentation window follows the approach of HTML5 Web Messaging. You can call postMessage
to post a message and register an onmessage
event listener to handle the message from the other side.
If an error occurs, requestShow
will fail and the errorCallback
method is called with a DOMError object. The following table describes the possible errors:
| Error Name | Description |
|---|---|
| NotFoundError | No available secondary display found |
| InvalidAccessError | A presentation is already showing on the secondary display |
| NotSupportedError | The platform doesn't support the Miracast protocol |
| InvalidParameterError | An invalid url parameter was passed |
Note: Since there is no input channel on the secondary display, we recommend:
- Design an easy-to-read user interface for a large display.
- Avoid JavaScript dialogs (e.g. alert and confirm).
- Do not expect click, touch or keyboard events or interaction in the presentation page context.
presentation.displayAvailable Property
The presentation.displayAvailable
property is true if there is at least one secondary display available for showing a presentation; otherwise, it is false. When one secondary display is disconnected:
- If it is not the only secondary display connected to the device, the page content will be switched to the next available display automatically.
- If it is the only secondary display, the page content is disposed of and the
displayAvailable
property is set to false.
presentation.displayavailablechange Event
The displayavailablechange
event is fired when the first secondary display becomes available or the last secondary display is removed. The property of displayAvailable
will also be updated to true or false (see above).
The presentation browsing context is closed if the secondary display becomes unavailable. The app does not need to close it.
Summary
In this tutorial, we introduced a new W3C Presentation API for presenting web content on a secondary display. Currently, it is an experimental feature implemented in Crosswalk for Android 4.2+ devices. It may be changed in the future as it evolves based on feedback from the community.

>Microsoft has just announced codename "Astoria":
"Astoria exposes "data services" that enable applications to access and manipulate data over regular HTTP connections, using URIs to identify pieces of information within the data service, and simple payload formats such as XML and JSON to represent the data exchanged between the client and the server"
As far as I know this has been around since 2000 and is called REST. Personally I'm not a big believer in REST but if MS deems it mature enough to invest in it might be worth another try.

8.4. Conditional Expressions (aka "the Ternary Operator")
If you are coming from the C/C++ or Java world, it is difficult to ignore or get over the fact that Python has not had a conditional or ternary operator (C ? X : Y) for the longest time. (C is the conditional expression; X represents the resultant expression if C is true and Y if C is False.) van Rossum Guido has resisted adding such a feature to Python because of his belief in keeping code simple and not giving programmers easy ways to obfuscate their code.
However, after more than a decade, he has given in, mostly because of the error-prone ways in which people have tried to simulate it using and and or, many times incorrectly. According to the FAQ, the one way of getting it right is (C and [X] or [Y])[0]. The only problem was that the community could not agree on the syntax. (You really have to take a look at PEP 308 to see all the different proposals.) This is one of the areas of Python in which people have expressed strong feelings.
The final decision came down to van Rossum Guido choosing the most favored (and his most favorite) of all the choices, then applying it to various modules in the standard library. According to the PEP, "this review approximates a sampling of real-world use cases, across a variety of applications, written by a number of programmers with diverse backgrounds." And this is the syntax that was finally chosen for integration into Python 2.5: X if C else Y.
The main motivation for even having a ternary operator is to allow the setting of a value based on a conditional all on a single line, as opposed to the standard way of using an if-else statement, as in this min() example using numbers x and y:
>>> x, y = 4, 3
>>> if x < y:
... smaller = x
... else:
... smaller = y
...
>>> smaller
3
In versions prior to 2.5, Python programmers at best could do this:
>>> smaller = (x < y and [x] or [y])[0]
>>> smaller
3
In versions 2.5 and newer, this can be further simplified to:
>>> smaller = x if x < y else y
>>> smaller
3

- Genetic Concepts
- Evolutionary Computation
- Genetic Operators
- Chromosome Representation
Genetic Operators
A genetic operator is an operator used in genetic algorithms to guide the algorithm toward a solution; mutation, crossover, and selection which should work together for the algorithm to be successful.Note that the same individual may be selected as both parents; and same individual may take part in producing more than one offspring.
Main driving operators in genetic algorithm
- Selection, to model survival of the fittest.
- Recombination, to model reproduction.
- Mutation, to introduce new genetic materials.
In selection of parents
Selection is the stage, in which individual genomes are chosen from a population for later breeding. Crossover occurs at a crossover probability of p_c. We can use any selection operators.
Selection process can be described by two steps
- Parent selection
- A replacement strategy that decides if offspring will replace parents, and which parents to replace.
Reproduction
Process of producing offspring from selected parent by crossover and/or mutation operators.
Crossover
Producing one or more new individuals, through the combination of genetic materials randomly selected from two or more parents.
We produce offspring, by combining genetic material from parents.
Main categories of crossover operators
- Asexual: an offspring is generated from one parent.
- Sexual: two parents produce one or two offspring.
- Multi-recombination: more than two parents are used to produce one or more offspring.
Mutation
The process of randomly changing the values of genes in chromosome.
- The main objective is introducing new genetic material to our population and increasing diversity.
- Mutation probability (p_m) and step sizes should be small.
About Mutation
The objective is to introduce new genetic material to population and adding diversity to the genetic characteristics of population. We can ensure that the full range of allele, is accessible for each gene. Mutation probability is p_m. Given that each gene is mutated at probability p_m, the probability that an individual will be mutated is:
Prob (x_i (t) is mutated) = 1 - (1-p_m )^(n_x )
(1-p_m ) is the probability that one gene is not mutated and (1-p_m )^(n_x ) is the probability that all the genes in an individual are not mutated. n_x is the length of the individual.
Effects of control parameters
- Population size
- Mutation rate, p_m
- Crossover rate, p_c
Large initial mutation rate favors exploration. As mutation rate decreases, exploration is favored.
For floating-point representation, mutation step size influences performance.
Large mutational step sizes cause large jumps in search space and thus better exploration.
Step size should be proportional to fitness of individual.
The worse an individual, the larger the mutational step size.
Best values of parameters are problem-dependent.
Some techniques in mutation
- Mutate proportional to the fitness of the individual.
- Decrease the mutation probability over time.
When to stop our algorithm?
- When the number of generation, or fitness evaluations has reached to a specific number (for example: n <= 100)
- When population has converged: (How to know?)
- Terminate when no improvement is observed over a number of consecutive generations.
- Terminate when there is no change in the population.
- Terminate when an acceptable solution has been found.
- Terminate when objective function slope is approximately zero.
Generation Gap
The amount of overlap between the current and new population.
Replacement Strategies
- Replace worst: replace offspring with the worst individual in current population.
- Replace random: replace offspring with a random individual in current population.
- Kill tournament: replace an offspring with the worst individual in n_ts, using tournament selection.
- Replace oldest: use FIFO strategy and replace offspring with the oldest individual in the current population.
- Conservative selection: combine FIFO replacement with a modified deterministic binary selection.
- Elitism: The best individual is excluded from selection.
- Parent-offspring: a selection strategy is used to decide whether an offspring replaces one of its own parents.

The bugtraq reports that correspond to this change are: 4228939 and 4268962
In the JDK 1.2 and 1.3 common operations on a Graphics object often invalidated the rendering data cached for this Graphics object. This invalidation interrupted the rendering process by causing continuous re-creation of rendering information for the Graphics object, even for such simple and benign operations as create(), setColor(), and translate(). Because the rendering of Swing hierarchies relies heavily on these common operations, the invalidation and re-creation of rendering data caused poor repaint performance for many Swing applications.
The new pipeline architecture reduces this performance overhead with several implementation changes that:
Other changes in the pipeline architecture have greatly improved the performance of:
Hardware Acceleration for Offscreen Images
The bugtraq report that corresponds to this change is: 4330166
The JDK 1.4 provides access to hardware acceleration for offscreen images, resulting in better performance of rendering to and copying from these images. One problem with hardware-accelerated images is that, on some platforms such as Microsoft Windows, their contents can be lost at any time due to circumstances beyond the application's control. The new VolatileImage class allows you to create a hardware-accelerated offscreen image and manage the contents of that image.
This new API includes:
The bugtraq report that corresponds to this change is: 4101949
The Java Image I/O API is an pluggable, extensible framework that supports reading and writing images of various formats and protocols. The API provides this support through plug-ins, most of which will be written by third parties. A conforming implementation will only be required to provide a minimal set of plug-ins, principally for compatibility with previous versions of the Java SDK. An application using this API should be able to read and write images without knowing the image's storage format or the plug-in used to support the format.
Fundamentally, all image I/O operations consist of reading or writing streams that contain one or more images, one or more preview (thumbnail) images associated with each image, and metadata, which is everything other than pixel data.
The Java Image I/O API allows applications to:
See Java Image I/O for more information on the Java Image I/O API.
The bugtraq reports that corresponds to this change are:
4285177 and
4360752
This API is the product of JSR006, Unified Printing API, and will allow client applications to provide rich access to the capablities of print services available including:
Server applications can be beneficiaries of the capabilities for spooling documents to print services, whereas previously only graphics calls could be used to generate printer jobs from Java applications.
See Java Print Service for more information.
Support for float and double Image Types
The bugtraq report that corresponds to this change is: 4364491
Prior to the SDK 1.4, the Java 2D API did not have DataBuffer subclasses for float or double sample types. The Java Image I/O API needs these classes to read and write float and double image types.
The SDK 1.4 contains two new classes to provide float and double image type support: DataBufferFloat and DataBufferDouble. The DataBufferFloat class wraps float arrays of pixels. The DataBufferDouble class wraps double arrays of pixels.
The existing ComponentColorModel and ComponentSampleModel class implementations have also been updated to support signed short,float, and double data. These classes include definitions of the normalized ranges of component values for the newly-supported data types:
The complete additional API is listed below.
java.awt.image.ColorModel includes three new methods to parallel existing methods:
The bugtraq report that corresponds to this change is: 4285083
The Unicode Bidirectional Algorithm analyzes text using the Unicode character properties and determines the direction of runs of the text. The algorithm is necessary to properly display bidirectional text, such as Hebrew and Arabic text, in the correct order.
The current implementation is all written in the Java programming language, but the SDK 1.4 will include efficient access from native font code so that Hebrew and Arabic text can be more efficiently rendered. The SDK 1.4 will provide access to the native code through the Java Native Interface.
The new public Bidi class implements the Unicode 3.0 Bidi Algorithm and allows access to information on the bidirectional reordering of text so that the mixed, bidirectional text is properly displayed.
The example BidiSample demonstrates some of the Bidi routines.
Font Rasterizer support for TrueType hinting
Before this release, the T2K font rasterizer used by Java 2D did not support font-hinting for TrueType fonts. As a result, when TrueType fonts did not always display with a consistent, attractive appearance. For this release, the T2K rasterizer has been modified to use the hints stored in the TrueType fonts.
By adding this functionality to the T2K rasterizer, dependency on native rasterizers has been greatly reduced. Reducing this dependency results in:
The bugtraq report that corresponds to this change is: 4285089
For the SDK 1.4, the Lucida fonts that are in the Java SE will be upgraded to contain hints. This will give the Java SE higher quality fonts that could be used in place of existing fonts or if no other fonts are available. Adding hints to the Lucida fonts also allows the new cross-platform rasterizer to hint the Lucida fonts contained in the SDK, which causes the Lucida fonts to be displayed in a more consistent and attractive manner.
The bugtraq report that corresponds to this change is: 4285161
The SDK 1.4 includes a new architecture for providing general OpenType font support. This new architecture provides international character support for contextual scripts like Thai, Indic, Arabic, and Hebrew. It also provides enhanced typographical support for Roman languages.
The bugtraq report that corresponds to this change is: 4210199
Currently, when Java 2D renders numerals surrounded by Arabic text, the numerals have Arabic (roman) shapes, which are the commonly expected numeral shapes in most western countries. However, people in a Hindi locale expect to see Hindi shapes.
A new attribute, TextAttribute.NUMERIC_SHAPING, and a new class, NumericShaper, enable you to shape ASCII digits to other Unicode decimal ranges.
For example, to cause a TextLayout instance to convert digits from European to Arabic:
Numeric Shaper nS = NumericShaper.getContextualShaper(NumericShaper.ARABIC)
Map map = new HashMap(); map.put(TextAttribute.NUMERIC_SHAPING, nS);
FontRenderContext frc = ...; TextLayout layout = new TextLayout(text, map, frc);
layout.draw(g2d, x, y);
The NumericShaper class includes 19 constants representing different Unicode decimal ranges, allowing you to convert to 19 different digit shapes, including Devanagari and Thai.
Improved Complex-Layout Support in GlyphVector
Prior to this release, clients could not access glyph-to-character mapping information from GlyphVector. Clients can use this information to find out which glyphs in the GlyphVector correspond to which characters. This release also defines new methods to get the precise bounds of the GlyphVector and of individual glyphs within a GlyphVector.
Note: Although clients can use GlyphVector and the glyph-to-character mapping information to implement selection and hit testing, most clients will find TextLayout and the Swing JTextArea and JTextField classes to be more useful and convenient.
These GlyphVector methods are new in the SDK 1.4:
Shape
whose interior corresponds to the
visual representation of the specified glyph within this
GlyphVector
, offset to x, y.GlyphVector
when
rendered in a graphics with the given
FontRenderContext
at the given location.GlyphVector
is rendered in a Graphics
with the given FontRenderContext
at the given
location.The bugtraq report that corresponds to this change is: 4380232
The AlphaComposite class provides alpha blending capabilities according to modes or rules established by Porter and Duff. Out of the 12 rules that Porter and Duff identified, the AlphaComposite API for the SDK, version 1.3 defines and implements only 8 of them:
For the SDK 1.4, AlphaComposite implements the remaining 4 Porter-Duff rules:
Support for Checking if Font has a Transform
The bugtraq report that corresponds to this change is: 4314043
As of the SDK 1.2 the Font object has a transform attribute that can be accessed with the Font.getTransform method. You can perform geometric transformations, such as rotating and shearing, on the Font by setting the transform attribute. However, most applications use the Size attribute rather than the transform to control the size and shape of characters. In this case, the transform is a simple identity transform.
Currently, the only way to determine if the transform is an identity transform is to call getTransform and inspect the returned AffineTransform. Unfortunately, calling getTransform requires the Font object to clone the AffineTransform because the transform is mutable.
Two new methods in the SDK 1.4 allow you to check if a Font object's transform is an identity tranform without creating a new AffineTransform:
true
if the wrapped transform is an identity
transform.The bugtraq report that corresponds to this change is: 4328579
A FontRenderContext object encapsulates state about the graphics context and is used by GlyphVector and TextLayout. Three new methods in FontRenderContext allow you to compare the FontRenderContext in the GlyphVector against the one in the graphics context into which the GlyphVector draws:
These equals methods also have performance benefits because a client does not have to create an AffineTransform to perform an equality test.*As used on this web site, the terms "Java Virtual Machine" or "JVM" mean a virtual machine for the Java platform.

Regular expressions, abbreviated to REGEX or REGEXP, is special text used to search for patterns. A simple example would be using a wildcard like *.txt to search for all text files, only REGEX is more powerful and can be used to search for more complex patterns.
While it often looks like a confusing string of characters, REGEX is actually made of simple codes to represent different patterns. They can be strung together and used to search for a wide variety of characters and even spaces.REGEX can help simplify code, and often several lines of code can be condensed to just one with a simple REGEX.
REGEX expressions in Ruby begin and end with a / character. A very basic REGEX expression can search for a particular character. Simply place your character between the forward slashes and you'll have a REGEX!
/A/ for example, will search for a capital A.
/a/ for example, will search for a lower-case a.
You can also search for variations, which can be useful when dealing with hard-to-predict user input.
/gr[ea]y/ for example, will search for either grey or gray.
A dot works much like a star in a wildcard search, and will match any character except a line break character. For example, /gr.y/ will also return grey or gray, but will also return gr%y, so it's best used sparingly.
Not only can you match specific characters, but you can match words, spaces, digits and more.
/\w/ will match any word.
/\d/ will match any single digit.
/\s/ will match any space.
There is a vast library of possibilities for matching. With so many options, the best way to find as many as possible is to play around and experiment with them!

PULSE A film review by Mark R. Leeper
CAPSULE: The director of CURE brings a weird and very complex concept to the screen. One viewing will not be enough to understand fully the premise of PULSE. The idea is something about ghosts and the Internet. The film has an amazing apocalyptic style. Rating: 7 (0 to 10), +2 (-4 to +4)
Perhaps the most disturbing (and disturbed?) filmmaker in the world is Kiyoshi Kurosawa. His films all seem to have one style, bleak. The worlds he creates are terrifying and cold. Little known in the US to date, his films deliver the kind of horror that so many of our filmmakers promise and are unable to deliver. Most of his ideas are fresh and at the same time morbid. His 1998 film CURE, with one of his niftiest ideas, is just now getting a sadly limited release in the US and hopefully enough people will see it that his name will soon be one to conjure with. CURE is probably his classic. Last year he released SEANCE, a remake of SEANCE ON A WET AFTERNOON. That was perhaps a miscalculation inserting supernatural elements into a non-supernatural story. PULSE is Kurosawa back on form.
Taguchi, a young computer expert, is late with his delivery of some important software. Two co-workers go to his apartment and find it a dismal dark affair in spite of his computer equipment. Taguchi, acting very strangely, lets his friends look for the missing software. Meanwhile he slips behind a plastic curtain. When he fails to respond to calls his friends follow him behind the curtain and discover he has hanged himself. If that was not horror enough the body seems to disappear leaving just a strange dark mildew-like spot on the wall. Taguchi's computer seems to have been infected with some kind of computer virus.  But they are not entirely dead. Their spirits seem to remain present somehow in the real world and on the Internet. People who get the computer virus are asked if they want to see a ghost. If they say yes, they seem to be able to see real time images of the spirits still nearby somehow. The computer shows them impossible images of ghosts in their own rooms as seen from cameras that do not exist.  Instead the dead seem to be staying on earth and inhabiting computer viruses. There is some sort of passage between worlds having something to do with doors marked with red tape and strange electronic disturbances on computers. Leave it to Kurosawa to find a new kind of death.
This is a film that has more weird ideas piled together than LIFEFORCE and somehow Kurosawa makes the film all work. It may not totally convey his message of isolation and its parallels to death, but whatever it does convey is nightmarish.  Frequently the plot is advanced with character hunches being assumed to be fact. His plotting is frequently hard to follow and always very strange.
Junichiro Hayashi, the cinematographer who recently has been doing all of Kurosawa's films, creates a dark, cold, and gloomy tone. Images are obscured by semi-lighting or are behind plastic curtain. Scenes are not milked for their horror the way American exploitation films might. People are shot with guns but there is little if any blood in evidence. Seeing black silhouettes on computer screens is not immediately scary. Kurosawa is not going for and easy visual shock, but a deeper metaphysical dread.
Of any horror filmmaker in the world, Kiyoshi Kurosawa is the one to watch. I rate this metaphysical look at isolation a 7 on the 0 to 10 scale and a +2 on the -4 to +4 scale.

Ray Parlour explains lesson Unai Emery must learn from Arsene Wenger
Arsenal legend Ray Parlour believes Unai Emery needs to follow the example of Arsene Wenger to find a clear direction for his side
by Rich Jones, https://www.mirror.co.uk/authors/rich-jones/Arsenal legend Ray Parlour says Unai Emery must learn lessons from predecessor Arsene Wenger by transferring a clear plan to his players.
Emery has come under fire after a poor start to the season which has left the Gunners eight points off the top four and the Spaniard under pressure.
Former captain Parlour has questioned the lack of direction under Emery, stating he is still unsure of his best formation and system.
After making little progress over the last 18 months, Parlour believes Emery needs to focus on finding the right formula rather than chopping and changing.
He has called on him to follow Wenger's example of ensuring each player knows their job to deliver better results on matchdays.
Parlour told talkSPORT : “Emery doesn’t know his best team and he doesn’t know his best formation, but he should know! You’ve got to work on these formations. Do they work on them?
“[Mesut] Ozil was frozen out and now he’s back in favour, and defensively they’re still not solid enough.
“All these things are not in the right direction for Arsenal at the moment.
“I don’t mind three at the back, but you’ve got to work on it week in, week out in training, so the players know exactly what their jobs are as a team and then we can maybe move up the league.
“He needs to say the formation we’re going to play and stick to it!
“You can’t keep changing systems. At the moment it’s 4-2-3-1, then it’s 4-3-3 and then it’s three at the back, nobody really knows!
“It’s about finding the right formula and then working with the players so they understand how he wants them to play, and then it’s down to them when they cross the white line.
“That’s why Arsene Wenger did so well. He trained you, everyone knew their jobs and then he’d leave you alone and say, ‘on match day it’s down to you’.”

SUCKERS A film review by Steve Rhodes Copyright 2000 Steve Rhodes RATING (0 TO ****): ***
Director Roger Nygard, whose last film was the hilarious documentary called TREKKIES, this time makes a fictional film, SUCKERS, about car salesmen. He said at our screening that the story was 95% based on real incidents and that his writing partner for the picture, Joe Yanetty, is an ex-car salesmen. The picture is such an honest and effective comedy that HBO has not only bought his movie, they've also committed to make a series based on it as well.
Bobby (Louis Mandylor) is an unemployed ex-truck driver who has two loan sharks after him. Facing financial ruin, he follows his wife's demands and takes a job at the automobile dealership where she works in the office.
At his Saturday morning sales meeting, the take-no-prisoners general manager, Reggie (Daniel Benzali), lectures his troops like General Patton. Nygard said the two films that influenced this picture the most were GLENGARRY GLEN ROSS and CLERKS. The foul-mouthed, scary and funny sales meeting certainly pays homage to the first of these two pictures.
The salesmen bet on everything and like nothing better than conning their customers out of their last nickel. Reggie preaches a simple, Ayn Rand philosophy of business conduct when dealing with buyers. "If he makes a good deal, he takes money out of your pocket," Reggie lectures his minions. "If you make a good deal, you take money out of his." Actually most of Reggie's comments are unprintable.  At the dealership, sexual activities are used among the sales force as the universal metaphor for car selling.
As much as it is easy to ridicule all of Reggie's advice, much of it applies to everyone with a sales job, although one hopes that most people in sales are a bit more humane. "When does the salesman's job start?" he asks his pupils. "The salesman's job starts when the customer says 'no,'" he tells them, answering his own question.
Many of the car selling techniques you probably have experienced yourself, but others may surprise you. One of the salesmen, JJ, played by BT, is actually a dead ringer for our last car salesman. JJ even had the same lovable, gregarious manner about him. The director said that they spent over three months in the casting of all of the parts so that the movie would feel genuine, which it does. I asked him if BT used to work as a car salesman in the Silicon Valley, but it turned out that he hadn't.
With so many variables involved (new car price, trade-in value, monthly payment, down payment, etc), the salesmen are able to bamboozle the buyers by constantly changing various combinations of them. And once the salesman has gotten the deal that he wants, he tries to switch the customers to a bad lease arrangement instead and make even more money. Playing good guy/bad guy, the salesmen, closers and managers leave the customers not knowing whether they are coming or going.
Eventually Bobby develops some second thoughts about his conduct. "We're so good at it that when we're done, they think we're heroes for doing it," he says in disgust of their manipulation of their customers. But Reggie sees life at the dealership as a daily fight for survival of the fittest. "Be the best you can be," he barks at his men. "Never apologize for it!" One thing is certain, the energetic movie tries hard to be the best that it can be, which is a lot of fun.
SUCKERS runs a lightning fast 1:27. It is not yet rated but will undoubtedly be an R for language, sex, nudity and violence. The film would be acceptable for older teenagers.

when my heart is faint.
Lead me to the rock
that is higher than I,
3 for you have been my refuge,
a strong tower against the enemy.
4 Let me dwell in your tent forever!
Let me take refuge under the shelter of your wings!
Selah
5 For you, O God, have heard my vows;
you have given me the heritage of those who fear your name.
6 Prolong the life of the king;
may his years endure to all generations!
7 May he be enthroned forever before God;
appoint steadfast love and faithfulness to watch over him!
8 So will I ever sing praises to your name,
as I perform my vows day after day.

The documentation for this class was generated from the following files:


The Scripting Bundle Maven Plugin will look for scripts in two project directories:
The structure in these source directories should then follow the normal way of structuring scripts in an Apache Sling application. For more details, check the URL to Script Resolution page. In addition to the normal way of structuring scripts in the file tree, the plugin provides some additional features:
Resource Type Versioning
This works by putting the scripts in a folder that follows this simple naming convention: <resourceType>/<version>/. The <version> should be a valid semantic version (e.g. 1.0.0)
Defining explicit extends relationships (similar to the sling:resourceSuperType property)
An extends file in the resource type folder (versioned or not) allows defining this explicit relationship. This file must contain a single line with the resourceType used for the extends capability attribute followed by a ;version=<version-range>; in this case, the plugin will set the extends attribute to the given resourceType and generate a Require-Capability for that resourceType with the given version range.
Defining an explicit requirement, without an inheritance relationship (e.g. delegation to another resource type)
A requires file (assuming the same conventions and syntax as for the extends file) will generate a Require-Capability for each line based on the given resourceType and version range.
The Resource Type can have the form of a path or of a Java package name (e.g. com.mydomain.components.image). When the resource type is defined as a package name, the resource type label will be the last subpackage (i.e. for com.mydomain.components.image, the resource type label will be image).
As an example, let’s assume the following layout:
src/main/resources/javax.script/ org.foo/1.0.0 foo.POST.html
This will generate following Provide-Capability:
sling.servlet; sling.servlet.resourceTypes:List<String>="org.foo"; sling.servlet.methods:List<String>=POST; version:Version="1.0.0"

The plugin doesn’t currently integrate with the maven-bundle-plugin, nor the bnd-maven-plugin. However, the generated Require-Capability and Provide-Capability headers values are simply made available via properties:
${org.apache.sling.scriptingbundle.maven.plugin.Require-Capability} ${org.apache.sling.scriptingbundle.maven.plugin.Require-Capability}
That makes it reasonable straightforward to use the plugin by just adding it into your build in the prepare-package phase and use the two properties in the manifest writing instructions of another plugin like the maven-bundle-plugin:
<plugin> <groupId>org.apache.sling</groupId> <artifactId>scriptingbundle-maven-plugin</artifactId> <version>0.2.0</version> <executions> <execution> <phase>prepare-package</phase> <goals> <goal>metadata</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.felix</groupId> <artifactId>maven-bundle-plugin</artifactId> <extensions>true</extensions> <configuration> <instructions> <Provide-Capability> ${org.apache.sling.scriptingbundle.maven.plugin.Provide-Capability} </Provide-Capability> <Require-Capability> osgi.extender;filter:="(&(osgi.extender=sling.scripting)(version>=1.0.0)(!(version>=2.0.0)))", ${org.apache.sling.scriptingbundle.maven.plugin.Require-Capability} </Require-Capability> </instructions> </configuration> </plugin>
