海外TECH	DEV Community	Writing Clean and Consistent Code with Static Analysis using PMD and Apex	https://dev.to/salesforcedevs/writing-clean-and-consistent-code-with-static-analysis-using-pmd-and-apex-nn3	Writing Clean and Consistent Code with Static Analysis using PMD and ApexOne of the key requirements to developing good maintainable software is to ensure that it works under a variety of conditions This is typically done by automating a suite of tests on the various features and code paths your application can take While unit tests are excellent for making sure that your application technically runs there s another category of verification which ensures that your application has no other detectable issues static analysis Static analysis is a method of analyzing your code without executing it If you ve ever worked with a compiled language like Kotlin the compiler implements one form of static analysis by ensuring that your program adheres to the grammatical rules of the language For example if you call a function but forget to pass in required arguments a static analyzer alerts you to this error before you compile your application This is in contrast to an interpreted language such as JavaScript in which the error would occur when executing the code because there s no compiler to anticipate the issue To be technically precise a static analyzer can be applied to interpreted languages like JavaScript Ruby or Python ensuring that the code is well formatted and has no missing logic Benefits of Static AnalysisWhile a well written test suite is likely to cover such code paths static analysis can do so much more A static analyzer can reduce the possibility of bugs such as when you accidentally overwrite a variable with another value It can also implement linting and formatting rules which make your codebase consistent and easier to review Some static analyzers even bring performance benefits by suggesting ways to rewrite loops or other functional calls Nearly every programming language has a static analyzer of its own For example golang has gofmt which is baked into the standard tooling while Ruby has Rubocop a community led project Even compiled languages like C have their own static analyzer through astyle However it can be difficult and tedious to run several analyzers across polyglot projects Fortunately that s where a project like PMD can be of assistance PMD is a static analyzer that allows you to define a standard set of rules that can be applied over multiple languages In this post we ll take a closer look at PMD and learn how to run it on Apex code Our Apex project will have several issues that PMD can report and act on We ll also integrate PMD into your editor as well as your CI environment to make sure that your build will fail if the static analysis detects any problems PrerequisitesBefore getting started you should have some familiarity with Apex Salesforce s programming language which unlocks new possibilities for your organization We ll be using VS Code along with the Apex plugin You ll also need the Salesforce CLI which is a tool designed by Salesforce to simplify interacting with the platform Next go ahead and follow the installation instructions for PMD Finally clone our sample Apex project at this Git repository This repository is a forked copy of the dreamhouse lwc project except it has intentionally introduced some errors We ll use this to demonstrate how PMD works Integrating PMDFirst enable Dev Hub for your Salesforce organization If you don t have a Salesforce instance no worries You can create a scratch org which is like a temporary Salesforce org You can use the scratch org to test what developing on the Salesforce platform looks like Whether you re using a scratch org or your own you ll need to associate sfdx with the org by logging in Run the following command to do so sfdx auth web loginThis will open a new browser window that will ask for your Salesforce credentials When that s finished the Salesforce CLI will inform you when the authentication is complete Now let s see what happens when we try to upload the cloned project to our org Navigate to the directory you cloned the dreamhouse sfdx project to and run the following command sfdx force source push u lt admin email address gt You should see the following output Deploying with SOAP Job ID AfRXgjRKAJSOURCE PROGRESS ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ComponentsTYPE PROJECT PATH PROBLEMーError force app main default classes PagedResult cls Unexpected token Error force app main default classes PagedResult cls Unexpected token set ERROR running force source push Push failed Uh oh It looks like there were several issues in this file stemming from missing semicolons How d that get past code review Open up force app main default classes PagedResult cls in VS Code and add a semicolon to the end of the statements on lines and That should solve the problem right Well perhaps not While our code compiles and has no build errors our project may have some other issues we re not aware of On the command line type the following command pmd d R config ruleset xmlHere we re running PMD on the current directory d and we re applying a ruleset located at config ruleset xml When you execute this command you ll see dozens of lines that look like this main default classes PostPriceChangeToSlackTest cls DebugsShouldUseLoggingLevel Calls to System debug should specify a logging level main default classes PropertyController cls AvoidGlobalModifier Avoid using global modifiermain default classes SampleDataController cls UnusedLocalVariable Variable brokersJSON defined but not usedThis is the power of PMD According to our ruleset PMD identified several issues in our project We re missing the logging severity level We re using global modifiers which could have unwanted side effects We re creating unused local variables which is a waste of memory and time Open up the config ruleset xml file and you ll find an XML document that lists several rules These rules map to the issues which PMD will report on Believe it or not there are hundreds of Apex rules and you can find the full set at the PMD repo You have complete control over which rules to enable Typically you d determine which ones are important by agreeing with your teammates on the ones that matter most After all their code will be statically analyzed too Integrating PMD in VS CodeSwitching to the command line to statically analyze your code can get a bit tedious if not outright disruptive to your workflow Since static analysis looks at the structure of your code without compiling it you can integrate tools like PMD directly into your editor That means you can get feedback on your code as you re writing it Fortunately several plugins allow you to integrate PMD into VS Code Let s install one and see what that process looks like Visit the Apex PMD extension homepage on the VS Code Marketplace and click Install This downloads the plugin and installs it into your editorーbut we re not finished just yet The Apex PMD extension comes with its own ruleset which while convenient may not be the same rules you ve established for your project We ll need to configure the tool to point to our predetermined ruleset Open up the VS Code settings page this can be found in the menu bar under Code gt Preferences gt Settings and type pmd to filter the settings to just that extension Then in the Rulesets section set the path to the ruleset xml file we created in this project Next navigate to any cls file in your project You ll see varying squiggly lines indicating the issues found by PMD Hovering over these lines also presents a dialog box indicating what the issue is as well as which rule triggered it Integrating PMD in CIHaving PMD run while writing your code is a good step towards catching issues before they enter production However the very best way to do this is to set up your PMD analysis as part of the test suite in your CI CD pipeline The first step is to install PMD on your CI servers You can do this by grabbing a containerized version of the program or by downloading the package with wget and unzipping it If you re using GitHub Actions you can just integrate an action such as this one which takes care of all the installation and configuration for you If you re not you simply need to run PMD as you do on the CLI within a script bin shset epmd d R config ruleset xmlSince PMD fails with a non zero status running this script will mark your CI as a failure too if there are any issues ConclusionStatic analysis not only helps keep your code consistent and clean but it can also help make it more efficient by pointing out small inconsistencies that could add up to bigger problems It should be an important tool in your toolbox In addition by integrating static analysis with your CI tests you can rest assured that once your code is fixed it stays fixed To learn more about how to write better Apex code Salesforce has some Trailhead badges with some advanced topics The PMD documentation also details all of the available Apex rules you can use Salesforce also has a whole suite of tools that can be installed as plugins to make writing code much easier	2022-01-28

investor relations website has become an important tool for companies to communicate with their investors It has also become an important part of the investor relations department of a company This blog will look at different aspects of creating an effective section for an investor relations website Investor Relations is an important part of a company s communication with the outside world It is a channel to ensure that there is transparency with the company and its stock holders This channel ensures that both parties get updates on the company s progress growth finances and also allows both parties to exchange ideas and suggestions The importance of an IR websiteAn investor relations website is a business website that is built specifically for the management of a company to meet the needs of stakeholders or investors of a company who are looking for information on the company The investor relations website is also known as investor relations portal It serves as a platform to allow investors to interact directly with the management of a company An Investor Relations IR website is designed for external use and is used primarily to communicate with investors and other stakeholders IR sites are typically run by automated content management systems that are used to generate news and information in conjunction with financial disclosure documents What makes a good IR website International relations are becoming more and more important in this age of globalization Foreign companies are looking to expand to new markets and local companies are looking to find new potential partners The internet is an excellent way to do this but it does have its drawbacks A good investor relations website serves the purpose by being clear and concise It is necessary for an investor relations website to be able to communicate complex concepts in simple and easy to understand language A good IR website should be able to explain high level concepts and also offer links to more in depth writing An effective Investor Relations website helps issuers to communicate with their investors It is an online channel that offers information about the company and helps to create awareness about the company its products and services and keeps investors and potential investors informed about the company s progress and performance And thus it helps in increasing the company s brand visibility among target stakeholders Integrate ESG Content into Your IR WebsiteAs explained in an earlier blog ESG content is a high priority area in IR This ESG website is highly interactive and provides an opportunity to integrate prospective employees and employers by creating an online IR community The demand for and production of ESG content has skyrocketed over the past several years This is due to many different factors but the most important factor is shareholders continued desire to better understand the companies they invest in ESG environmental social and governance content is not new but it has now become a more common place component of a company s IR website Many investors want to know more about the sustainability of the companies they invest in Using ESG content is one way that companies can provide this information and build trust among their investors and other stakeholders Best practices for IR websitesAn Investor Relations IR website is a website that is used to support the communication between an organization and its shareholders These websites are typically used by public companies However private companies that are considering going public are also encouraged to develop an IR website An IR website is a first point of contact for a company s shareholders Therefore the company must ensure that the website is simple direct intuitive and easy to use This blog will look at the best practices of an IR website Core Investor Relations Website ElementsThe main elements of any IR website should include the following About UsThe purpose of this section is to share your company s story with potential investors and explain why they will benefit from investing in you Financial InformationIn order to be valuable to investors investors should be able to find the most recent financial reports and key highlights easily from the IR homepage Company press releases reports and filings should also be organized into an archive Stock MarketInclude the live stock price relevant information and an updated calendar ContactProvide an easily accessible contact form an email address a physical address and a telephone number Wrapping UpThe best practices for IR websites tend to be the same as the best practices of any website An effective IR website section can be created by keeping certain points in mind It is important to be clear concise

海外TECH	DEV Community	Streaming Data Solutions on AWS - Part 1	https://dev.to/aws-builders/streaming-data-solutions-on-aws-part-1-3io6	Streaming Data Solutions on AWS Part Businesses today receive data at massive scale and speed due to the explosive growth of data sources that continuously generate streams of data Whether it is log data from application servers clickstream data from websites and mobile apps or telemetry data from Internet of Things IoT devices it all contains information that can help you learn about what your customers applications and products are doing right now Having the ability to process and analyze this data in real time is essential to do things such as continuously monitor your applications to ensure high service uptime and personalize promotional offers and product recommendations Processing streams of data with AWS Lambda Streaming data solutions on AWS is a series containing different articles that review several scenarios for streaming workflows In these scenarios streaming data amp processing it provides the example companies with the ability to add new features and functionality By analyzing data as it gets created they can gain insights into what their business is doing AWS streaming services enable you to focus on your application to make time sensitive business decisions rather than deploying and managing the infrastructure Scenario Internet offering based on locationCompany InternetProvider provides internet services with a variety of bandwidth options to users across the world When a user signs up for internet company InternetProvider provides the user with different bandwidth options based on user s geographic location Given these requirements company InternetProvider implemented an Amazon Kinesis Data Streams to consume user details and location The user details and location are enriched with different bandwidth options prior to publishing back to the application AWS Lambda enables this real time enrichment Amazon Kinesis Data StreamsAmazon Kinesis Data Streams enables you to build custom real time applications using popular stream processing frameworks and load streaming data into many different data stores A Kinesis stream can be configured to continuously receive events from hundreds of thousands of data producers delivered from sources like website click streams IoT sensors social media feeds and application logs Within milliseconds data is available to be read and processed by your application When implementing a solution with Kinesis Data Streams you create custom data processing applications known as Kinesis Data Streams applications A typical Kinesis Data Streams application reads data from a Kinesis stream as data records Data put into Kinesis Data Streams is ensured to be highly available and elastic and is available in milliseconds You can continuously add various types of data such as clickstreams application logs and social media to a Kinesis stream from hundreds of thousands of sources Within seconds the data will be available for your Kinesis Applications to read and process from the stream Amazon Kinesis Data Streams is a fully managed streaming data service It manages the infrastructure storage networking and configuration needed to stream your data at the level of your data throughput Sending data to Amazon Kinesis Data StreamsThere are several ways to send data to Kinesis Data Streams providing flexibility in the designs of your solutions You can write code utilizing one of the AWS SDKs that are supported by multiple popular languages You can use the Amazon Kinesis Agent a tool for sending data to Kinesis Data Streams The Amazon Kinesis Producer Library KPL simplifies the producer application development by enabling developers to achieve high write throughput to one or more Kinesis data streams The KPL is an easy to use highly configurable library that you install on your hosts It acts as an intermediary between your producer application code and the Kinesis Streams API actions For more information about the KPL and its ability to produce events synchronously and asynchronously with code examples see Writing to your Kinesis Data Streams Using the KPLThere are two different operations in the Kinesis Data Streams API that add data to a stream PutRecords and PutRecord The PutRecords operation sends multiple records to your stream per HTTP request while PutRecord submits one record per HTTP request To achieve higher throughput for most applications use PutRecords For more information about these APIs see Adding Data to a Stream The details for each API operation can be found in the Amazon Kinesis Data Streams API Reference Processing data in Amazon Kinesis Data StreamsTo read and process data from Kinesis streams you need to create a consumer application There are varied ways to create consumers for Kinesis Data Streams Some of these approaches include using Amazon Kinesis Data Analytics to analyze streaming data using KCL using AWS Lambda AWS Glue streaming ETL jobs and using the Kinesis Data Streams API directly Consumer applications for Kinesis Data Streams can be developed using the KCL which helps you consume and process data from Kinesis Data Streams The KCL takes care of many of the complex tasks associated with distributed computing such as load balancing across multiple instances responding to instance failures checkpointing processed records and reacting to resharding The KCL enables you to focus on the writing record processing logic For more information on how to build your own KCL application see Using the Kinesis Client Library You can subscribe Lambda functions to automatically read batches of records off your Kinesis stream and process them if records are detected on the stream AWS Lambda periodically polls the stream once per second for new records and when it detects new records it invokes the Lambda function passing the new records as parameters The Lambda function is only run when new records are detected You can map a Lambda function to a shared throughput consumer standard iterator You can build a consumer that uses a feature called enhanced fan out when you require dedicated throughput that you do not want to contend with other consumers that are receiving data from the stream This feature enables consumers to receive records from a stream with throughput of up to two MB of data per second per shard For most cases using Kinesis Data Analytics KCL AWS Glue or AWS Lambda should be used to process data from a stream However if you prefer you can create a consumer application from scratch using the Kinesis Data Streams API The Kinesis Data Streams API provides the GetShardIterator and GetRecords methods to retrieve data from a stream In this pull model your code extracts data directly from the shards of the stream For more information about writing your own consumer application using the API see Developing Custom Consumers with Shared Throughput Using the AWS SDK for Java Details about the API can be found in the Amazon Kinesis Data Streams API Reference Processing streams of data with AWS LambdaAWS Lambda enables you to run code without provisioning or managing servers With Lambda you can run code for virtually any type of application or backend service with zero administration Just upload your code and Lambda takes care of everything required to run and scale your code with high availability You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app AWS Lambda integrates natively with Amazon Kinesis Data Streams The polling checkpointing and error handling complexities are abstracted when you use this native integration This allows the Lambda function code to focus on business logic processing You can map a Lambda function to a shared throughput standard iterator or to a dedicated throughput consumer with enhanced fan out With a standard iterator Lambda polls each shard in your Kinesis stream for records using HTTP protocol To minimize latency and maximize read throughput you can create a data stream consumer with enhanced fan out Stream consumers in this architecture get a dedicated connection to each shard without competing with other applications reading from the same stream Amazon Kinesis Data Streams pushes records to Lambda over HTTP By default AWS Lambda invokes your function as soon as records are available in the stream To buffer the records for batch scenarios you can implement a batch window for up to five minutes at the event source If your function returns an error Lambda retries the batch until processing succeeds or the data expires SummaryCompany InternetProvider leveraged Amazon Kinesis Data Streams to stream user details and location The stream of record was consumed by AWS Lambda to enrich the data with bandwidth options stored in the function s library After the enrichment AWS Lambda published the bandwidth options back to the application Amazon Kinesis Data Streams and AWS Lambda handled provisioning and management of servers enabling company InternetProvider to focus more on
