Have you noticed the OpenSSF Scorecard badges on the official Dart and Flutter repos? It's Google's way of showing that they care about security. Practices such as pinning dependencies, branch protection, required reviews, continuous integration tests etc. are measured to provide a score and accompanying badge.
You can do the same for your projects, and this presentation will show you how, with an emphasis on the unique challenges that come up when working with Dart and Flutter.
The session will provide a walkthrough of the steps involved in securing a first repository, and then what it takes to repeat that process across an organization with multiple repos. It will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil.

Mitigating the Impact of State Management in Cloud Stream Processing Systems
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.

SenchaCon 2016: How to Auto Generate a Back-end in Minutes - Per Minborg, Emi...Sencha
The document describes how Ext Speeder can auto-generate a complete backend in minutes by graphically connecting to a database, selecting tables and columns, and pressing "Generate". This generates code that provides a REST API and handles tasks like filtering, sorting, skipping, and caching data for high performance. Ext Speeder aims to reduce traditional backend development time from around 24 hours to under 1 hour.
This document discusses technologies for creating and maintaining web applications. It covers Ruby and the Rails framework. Ruby is designed to be programmer-focused rather than machine-focused, helping create dynamic and self-explained code. Rails enables quickly building web servers through conventions, reuse, single responsibility principles, and features that provide quick setup, deployment, and built-in scalability. The document also discusses front-end architecture with client-side logic, and Rails features for development, deployment, databases, assets, and multi-environment configuration.
The document discusses different workflows for using Entity Framework to access and manage data, including model first, database first, and code first approaches. It also covers using Entity Framework with WCF Data Services to expose data via OData endpoints. Key topics include entity data models, reverse engineering databases, defining mappings, and generating databases from code using migrations. Live demos are provided for database first and code first workflows as well as creating and consuming a WCF Data Services API.
JDD2015: Java Everywhere Again—with DukeScript - Jaroslav TulachPROIDEA
JAVA EVERYWHERE AGAIN—WITH DUKESCRIPT
For a long time, Java was perfect for creating cross-platform applications, but the advent of iPhone, iPad, and Android devices changed everything, resulting in a totally fragmented world. Catering to all these platform is troublesome and expensive. That’s why DukeScript was created: to make it easy to create cross-platform Java applications again. The goal of this hands-on lab is to create a cross-platform application from scratch that will run on iOS, Android, desktop, browser, and embedded devices such as the Raspberry Pi. You’ll learn about the Model-View-ViewModel (MVVM) architecture, which enables you to write and test business code totally independently of the view, and, finally, you’ll see it combined with a view to complete a working application.
IMPORTANT
Before conference, please follow the steps to prepare for the session:
- perform the Maven repository initialization by creating the archetype and building it as
described at DukeScript website
- also download NetBeans IDE (either latest beta or at least 8.0.2)
- Installing Android SDK rev. 19 or bringing own Mac Book with XCode installed can be also found beneficial
Masterin Large Scale Java Script ApplicationsFabian Jakobs
Writing large desktop-like web applications is a challenge. Adapting such an application to different markets, languages or brands is even more of a challenge. This talk shows how the open source JavaScript framework qooxdoo can be leveraged to build such a rich internet application. As a real-life example the free web mail client gmx.com is used. This talk discusses the development model, customization and deployment of such an application.
Learn how JavaScript applications of this size and complexity are fundamentally different from classic web applications, and what issues come up when building fast, multi-language, multi-brand JavaScript applications.
Whether you are building a mobile app or a web app, Apache Usergrid (incubating) can provide you with a complete backend that supports authentication, persistence and social features like activities and followers all via a comprehensive REST API — and backed by Cassandra, giving you linear scalability.

AngularJS 1.x - your first application (problems and solutions)Igor Talevski
We will talk about all aspects of building a single page application with AngularJS, and we will discuss real examples from day-to-day work. We will also cover a large amount of theory about general web development, best practices, and today's client demands. We will focus on three (3) main points: architecture, security, and real time notification.
This document introduces Node.js and provides an overview of its key features and use cases. Some main points:
- Node.js is a JavaScript runtime built on Chrome's V8 engine that allows building scalable network applications easily. It is not a web framework but you can build web frameworks with Node.js modules.
- Node.js is well-suited for building web servers, TCP servers, command line tools, and anything involving high I/O due to its non-blocking I/O model. It has over 15,000 modules and an active community for support.
- Common use cases include building JSON APIs, single page apps, leveraging existing Unix tools via child processes, streaming

Fluttercon 2024: Showing that you care about security - OpenSSF Scorecards fo...Chris Swan
Have you noticed the OpenSSF Scorecard badges on the official Dart and Flutter repos? It's Google's way of showing that they care about security. Practices such as pinning dependencies, branch protection, required reviews, continuous integration tests etc. are measured to provide a score and accompanying badge.
You can do the same for your projects, and this presentation will show you how, with an emphasis on the unique challenges that come up when working with Dart and Flutter.
The session will provide a walkthrough of the steps involved in securing a first repository, and then what it takes to repeat that process across an organization with multiple repos. It will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil.

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.

2. Every Decision a Developer Makes is a
Trade-off
The best code is
no code at all
3. Using Code Generation
• Makes the code efficient
and short
• Modifications are done
once and applied
everywhere
• Minimizes errors
• “DRY” (Don’t Repeat
Yourself) vs. ”WET” (We
Enjoy Typing)
• “Code your code”
But how can we control the generated code?

Class.forName("org.postgresql.Driver");
try (final Connection conn = DriverManager.getConnection(
"jdbc:postgresql://hostname:port/dbname",
"username",
"password")) {
// Database Logic Here...
}
8. Why Creating DB-Apps is So Time
Consuming
• Even trivial database operations require a
lot of boilerplate code
• Mixing SQL and Java is error-prone
• ORMs require you to write annotated
POJOs for every table
• Creating even a simple DB app can take
hours
9. Open-Source Project Speedment
• Stream ORM Java toolkit and
runtime
• Generate domain-model from the
database
• No need for complicated
configurations or setup

14. So How Do the Generated Code Work?
• Code is organized based on database structure
• Hash-sums make sure user changes are not overwritten
If the DB structure changes, the code is
updated with the press of a button
15. Entities, Managers and Applications
• An Entity represents a row in a table
• Is a POJO
• Customer
• CustomerImpl
• A Manager represents a table
• Responsible for the CRUD operations
• CustomerManager
• CustomerManagerImpl
• An Application represents the entire project
• Responsible for configuration and settings
• SalesApplication
• SalesApplicationBuilder
16. Querying the Database using Streams
• Queries are expressed
using Java 8 streams
• Streams are analyzed to
produce high-performance
queries
17. Expressing Queries as Streams
customers.stream()
.filter(Customer.REGION.equal(Region.NORTH_AMERICA))
.filter(Customer.REGISTERED.greaterOrEqual(startOfYear))

• Reuse code segments and controllers
41. Java Language Namer
• Camel caser: converts from “some_db_name” to
“someDbName”
• Java naming conventions: user, User and USER
• Detects keywords like “final”,”static” and escapes them
• Detects collisions
• Pluralizer: bag → bags, entity → entities, fish → fish
42. Translator and TranslatorDecorator
• Translator
• Renders a DB entity like a Table to a new Class or an Interface
• TranslatorDecorator
• Modifies an existing Class or Interface
43. Maven Goals
• speedment:tool
• Launches the graphical tool

• speedment:reload
• Reloads database metadata without launching the tool
• speedment:clear
• Removes all the generated classes (except manual changes) without launching the
tool
44. Type Mappers
• Controls how columns are implemented
• Runtime conversion between Database and Java types
java.sql.Timestamp long
45. Generation vs. Templates
• Separation of concerns
• Easily change code style
• Minimize maintenance
• Maximize reusability
46. Generate a New Custom Class
1. Create a new Translator
2. Model how the new class
should look
3. Define a Plugin Class
4. Include it in project pom.xml
Example: Generate a Point class
47. Step 1: Create a New Translator Class
public class PointTranslator extends
AbstractJavaClassTranslator<Project, Class> {
public final static TranslatorKey<Project, Class> POINT_KEY =
new TranslatorKey.of(“generated_point", Class.class);
public PointTranslator(Project document) { super(document, Class::of); }
@Override
protected Class makeCodeGenModel(File file) {
return newBuilder(file, getClassOrInterfaceName())
.forEveryProject((clazz, project) -> {
// Generate Content Here
}).build();
}
@Override
protected String getClassOrInterfaceName() { return ”Point"; }
@Override
protected String getJavadocRepresentText() { return "A 2-dimensional coordinate."; }
}
Every translator is identified by a
TranslatorKey
Name of generated class
Javadoc
Called every time the translator is invoked
forEvery(Project|Dbms|Schema|Table|Column|
…)
49. Step 3: Define a Plugin Class
public class PointPlugin {
@ExecuteBefore(RESOLVED)
protected void install(CodeGenerationComponent codeGen) {
codeGen.put(
Project.class,
PointTranslator.POINT_KEY,
PointTranslator::new
);
}
}
The key defined earlier
Will execute when Speedment is
being initialized
How the translator is constructed
50. Step 4: Include it in Project pom.xml
<plugin>
<groupId>com.speedment</groupId>
<artifactId>speedment-maven-plugin</artifactId>
<version>3.0.0-EA</version>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.39</version>
</dependency>
<dependency>
<groupId>com.example</groupId>
<artifactId>point-plugin</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
</dependencies>
<configuration>
<components>
<component>com.example.pointplugin.PointPlugin</component>
</components>
</configuration>
</plugin>
This tells Speedment to load the plugin
Make sure our plugin project is on the classpath
51. Execute
/**
* A 2-dimensional coordinate.
* <p>
* This file is safe to edit. It will not be overwritten by
the code generator.
*
* @author company
*/
public class Point {
private final int x;
private final int y;
public Point(int x, int y) {
this.x = x;
this.y = y;
}
public int getX() {
return x;
}
public int getY() {
return y;
}
The following file is generated: public int hashCode() {
int hashCode = 31;
hashCode += 41 * x;
hashCode += 41 * y;
return hashCode;
}
public Boolean equals(Object other) {
if (this == other) return true;
else if (other == null) return false;
else if (!(other instanceof Point)) {
return false;
}
final Point point = (Point) other;
return x == point.x && y == point.y;
}
public String toString() {
return new StringBuilder(“Point{”)
.append(“x: “).append(x).append(“, “)
.append(“y: “).append(y).append(“}”);
}
}
52. A More Concrete Example
1. Create a new Translator
2. Model how the new class
should look
3. Define a Plugin Class
4. Include it in project pom.xml
Example: Generate an Enum of
tables in the database
53. Step 1: Create a New Translator Class
public class TableEnumTranslator extends
AbstractJavaClassTranslator<Project, Enum> {
public final static TranslatorKey<Project, Enum> TABLES_ENUM_KEY =
new TranslatorKey.of(“tables_enum", Enum.class);
public TableEnumTranslator(Project document) { super(document, Enum::of); }
@Override
protected Enum makeCodeGenModel(File file) {
return newBuilder(file, getClassOrInterfaceName())
.forEveryProject((clazz, project) -> {
// Generate Content Here
}).build();
}
@Override
protected String getClassOrInterfaceName() { return ”Tables"; }
@Override
protected String getJavadocRepresentText() { return "An enumeration of tables in the database."; }
}
Every translator is identified by a
TranslatorKey
Name of generated class
Javadoc
Called every time the translator is invoked
forEvery(Project|Dbms|Schema|Table|Column|
…)
55. Step 3: Define a Plugin Class
public class TableEnumPlugin {
@ExecuteBefore(RESOLVED)
protected void install(CodeGenerationComponent codeGen) {
codeGen.put(
Project.class,
TableEnumTranslator.TABLES_ENUM_KEY,
TableEnumTranslator::new
);
}
}

This tells Speedment to load the plugin
Make sure our plugin project is on the
classpath
57. Execute
/**
* An enumeration of tables in the database.

60. Add New Method to Existing Classes
• So far we have
• Queried a database with generated
classes
• Generated a custom class
• How do we modify the existing
generation of classes?
61. Add New Method to Existing Classes
• Fit Into Existing Class Hierarchy
• Change Naming Conventions
• Optimize Internal Implementations
• Add Custom Methods
62. Add New Method to Existing Classes
Example: Add a getColumnCount
method to generated managers
1. Create a new
TranslatorDecorator class
2. Write code generation logic
3. Add it to Speedment
63. Step 1: Creating a New Decorator Class
public class ColumnCountDecorator implements TranslatorDecorator<Table, Interface> {
@Override
public void apply(JavaClassTranslator<Table, Interface> translator) {
translator.onMake(builder -> {
builder.forEveryTable((intrf, table) -> {
// Code generation logic goes here
});
});
}
}
64. Step 2: Write Code Generation Logic
int columnCount = table.columns().count();
intrf.add(Method.of("getColumnCount", int.class)
.default_()
.set(Javadoc.of("Returns the number of columns in this table.")
.add(RETURN.setValue("the column count"))
)
.add("return " + columnCount + ";")
);
65. Step 3: Add it to Speedment
public final class TableEnumPlugin {
@ExecuteBefore(RESOLVED)
protected void install(CodeGenerationComponent codeGen) {
codeGen.put(
Project.class,
TableEnumTranslator.TABLES_ENUM_KEY,
TableEnumTranslator::new
);
codeGen.add(
Table.class,
StandardTranslatorKey.GENERATED_MANAGER,
new ColumnCountDecorator()
);
}
}
Modify an existing translator key
Our new decorator
The same plugin class as we
created earlier
