Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

20. Currently in production at major insurance company, 4 websites, clustered REST web services, internal tools, displacing legacy systems (Spring/Hibernate)
21. Meet new friend Navigate to: http://localhost:8080/testapp/greeting?name=Bob Executes: public class GreetingController extends AppController{ public void index(){ view(ānameā, param(ānameā)); } } Renders: /WEB-INF/views/greeting/index.ftl View code: Hello, ${name}! Output: Hello, Bob! A few conventions at work here: URL to Controller Default action view location by controller name view name by action name No configuration. In fact, ActiveWeb has no property files, no XML, no Yaml, no text files of any kind.
22. Lets TDD this public cla ss G r eetingControllerSpec extends ControllerSpec{ @Test public void shouldRenderHelloWorld(){ request().param(ānameā, āBobā).get(āindexā); a(assigns().get(ānameā)).shouldBeEqual(āBobā); } } Test HTML content: public class G reet ingControllerSpec extends ControllerSpec{ @Test public void shouldRenderHelloWorld(){ request().param(ānameā, āBobā). integrateViews () .get(āindexā); a(responseContent().contains(āHello, Bob!ā)).shouldBeTrue(); } } Convention at work: Controller name from spec name.
23. Configuration in code public class DbConfig extends AbstractDBConfig { public void init(AppContext context) { environment( "development" ) .jndi( "jdbc/kitchensink_development" ); environment( "development" ).testing() .jdbc( "com.mysql.jdbc.Driver" , "jdbc:mysql://localhost/kitchensink_development" , "root" , "****" ); environment( "hudson" ).testing() .jdbc( "com.mysql.jdbc.Driver" , "jdbc:mysql://172.30.64.31/kitchensink_hudson", "root", "****" ); environment( "production" ) .jndi( "jdbc/kitchensink_production" ); } } DSL for environments, JNDI, JDBC and testing mode You get help from IDE and from compiler, less likely to make a typo
24. Structure of project Standard Maven structure, View are located under: /WEB-INF/views Controllers are in app.controllers package . Result: Huge selection of anything built under the sun for Maven in general and Maven Web specifically
25. Layouts Default Layout: src/main/webapp/WEB-INF/views/layouts/default_layout.ftl < html > < head > < LINK href = "${context_path}/css/main.css" rel = "stylesheet" /> < script src = "${context_path}/js/jquery-1.4.2.min.js" </ script > < script src = "${context_path}/js/aw.js" </ script > < title > ActiveWeb - < @yield to = "title" /></ title > </ head > < body > < div class = "main" > < #include "header.ftl" > ${page_content} < #include "footer.ftl" > </ div > </ body > </ html > Serves the same purpose as Tiles or Sitemesh, but integrated into the system as another template. There are wrapper/nested layouts too.
26. <@content for and <@yield Page titles with custom tags < @content for = "title" > Books List </@content> This sends content to < @yield to = "title" /> located in layout Can send any content to layout with content tag, including links to CSS, JS, etc: < @content for = "js" > < script src = "${context_path}/js/page_specific.js" type = "text/javascript" ></ script > </ @ > Content will be rendered in layout in place of < @yield to = "js" /> This allows to easily declare content specific for a page, but rendered outside page context.
27. Unobtrusive JS and <@link_to < form id = "da_form" > First name: < input type = "text" name = "first_name" >< br > Last name: < input type = "text" name = "last_name" > </ form > < @link_to controller = "people" action = "do-get" form = "da_form" destination = "result" > Ajax Get </ @ > Result will be inserted into: < div id = "result" ></ div > No JavaScript is generated, the HTML page is clean More ways to use Ajax with link_to Magic happens in aw.js
28. Partials Naming src/main/webapp/WEB-INF/views/greeting/_hello.ftl Rendering a partial: < @render partial = "hello" /> Rendering a collection with a partial (no ugly for loops building iterative HTML): Content of _fruit.ftl : Fruit name: ${fruit}<hr> Host page: < @render partial = "fruit" collection = fruits /> Result of rendering: Fruit name: apple<hr>Fruit name: prune<hr>Fruit name: pear<hr> Partial will iterate itself. Also: spacers, counters, first and last.
29. Lets flash public class BooksController extends AppController { @POST public void create(){ Book book = new Book(); book.fromMap(params1st()); if (book.save()){ flash( "message" , "New book was added: " + book.get( "title" )); redirect(BooksController. class ); } else { //handle errors } } } //Use in view: < @flash name = "message" /> Flash is a short-lived object, survives only one more request Use in POST/redirect for destructive operations
30. Custom tags 1. Develop: public class HelloTag extends FreeMarkerTag{ protected void render(Map params, String body, Writer writer) throws Exception { writer.write(āhelloā); } } 2. Register: public class FreeMarkerConfig extends AbstractFreeMarkerConfig { public void init() { registerTag(āhelloā, new HelloTag()); } } 3. Use: < @hello />
31. Dependency Injection with Google Guice public class HelloController extends AppController { private Greeter greeter; public void index(){ view( "message" , greeter.greet()); } @Inject public void setGreeter( Greeter greeter) { this .greeter = greeter; } } public class GreeterModule extends AbstractModule { protected void configure() { bind(Greeter. class ) .to(GreeterImpl. class ).asEagerSingleton(); } } public class AppBootstrap extends Bootstrap { public void init(AppContext context) { setInjector(Guice.createInjector( new GreeterModule())); } }
32. TDD with DI public class GreeterMock implements Greeter{ public String greet() { return "Hello from " + getClass().toString(); } } public class GreeterMockModule extends AbstractModule { @Override protected void configure() { bind(Greeter. class ).to(GreeterMock. class ).asEagerSingleton(); } } public class HelloControllerSpec extends ControllerSpec { @Before public void before(){ setInjector(Guice.createInjector( new GreeterMockModule())); } @Test public void shouldTestWithMockService(){ request().get( "index" ); a(assigns().get( "message" )).shouldBeEqual( "Hello from class app.services.GreeterMock" ); } } Can use any mocking framework.
33. Making tests web specific ā Sendā parameters to controller: public class HelloControllerSpec extends ControllerSpec{ @Test public void shouldSendParamsToIndex(){ request() .param( "first_name" , "John" ).param( "last_name" , "Deere" ) .get( "index" ); a(assigns().get( "message" )) .shouldBeEqual( "Hello, John Deere, welcome back!" ); } } Seeing HTML in test! public class HelloControllerSpec extends ControllerSpec @Test public void shouldPrintGeneratedHTML(){ request(). integrateViews ().get( "index" ); System.out.println(responseContent()); // prints entire HMTL, decorated by layout. } }
42. REST web services Controller: public class Books Controller extends AppController { public void index(){ List<Book> books = Book.findAll(); view( " books", books); render().noLayout(); } } View: <? xml version = "1.0" encoding = "UTF-8" ?> < books > < #list books as book > < book > < isbn > ${book.isbn} </ isbn > < title > ${book.title} </ title > < author > ${book.author} </ author > </ book > </ #list > </ books > Access: http://host:port/context/books
43. What else can controllers do? //getting parameters String name = param(ānameā); List<String> selectValues = param(āmyselectā); List<String> params = params1st(); Map<String, String[]> allParams = params(); //passing data to view view(ānameā, name); assign(ānameā, name); //detecting Ajax: if (xhr()){...} else {...} //Responding directly (short hand XML service): respond( "<message>hello</message>" ) .contentType( "text/xml" ).status( 200 ); //sending view with no layout //(useful in web services when a view is used): render().noLayout();
44. Binary content in controllers //Downloading binary to client: sendFile(f).contentType( "application/pdf" ).status( 200 ); //Streaming large content: streamOut(in).contentType( "applicaiton/pdf" ); //Uploading files: Iterator<FormItem> iterator = uploadedFiles(); while (iterator.hasNext()){ FormItem item = iterator.next(); name = item.getName(); if (item.isFile()){ InputStream in = item.getInputStream()); //process data } }
45. @RESTful routing @RESTful public BooksController extends AppController{} verb path action used for ------------------------------------------------------------------------------------- GET /books index display a list of all books GET /books/new_form new_form HTML form for creating a new book POST /books create create a new book GET /books/id show display a specific book GET /books/id/edit_form edit_form return an HTML form for editing a books PUT /books/id update update a specific book DELETE /books/id destroy delete a specific book
46. Standard routing public BooksController extends AppController{ //GET by default public void index(){} @PUT public void save(); @DELETE public void delete(); @POST public void update(); } Allows only one HTTP method per action
47. GWT Support Compile GWT client.... and PRC server on the fly: GWT server: public class EchoController extends GWTAppController implements EchoService { public String echo(String text) { return "Hello from server :" + text + ",.... and time now is: " + new Date() ; } } GWT client: business as usual GWT DEMO
58. ActiveWeb has nice features for managing a DB connection at runtime and during tests ā tailored for ActiveJDBC, but in either case you can get access to java.sql.Connection and do with it as you wish:
