What's new in c# 6.0
What's new in c# 6.0LearningTech C# 6.0 focuses on small, useful features rather than large new concepts. It adds getter-only auto-properties, initializers for auto-properties, allows 'using' for static classes, introduces string interpolation for cleaner string formatting, expression-bodied methods for more concise syntax, index initializers in object initializers, null-conditional operators to simplify null checking, the nameof operator to tie names to code elements, exception filters to catch specific exceptions, and await in catch/finally blocks.

Functional programming in Javascript
Functional programming in JavascriptKnoldus Inc. Functional programming is a paradigm which concentrates on computing results rather than on performing actions. That is, when you call a function, the only significant effect that the function has is usually to compute a value and return it.
DotNet programming & Practices
DotNet programming & PracticesDev Raj Gautam DotNet Programming & Practices discusses various best practices for .NET development including:
1. Using proper naming conventions like PascalCasing for classes and methods and camelCasing for variables.
2. Properly documenting code with XML comments and avoiding inline comments. Only using regions for private fields, nested classes, and interface implementations.
3. Methods should perform a single task, not combine multiple jobs, and generally not exceed 25 lines. This increases maintainability.
4. Properties should be used over methods when the work is expensive or represents a conversion, and methods should be used when the result changes or causes side effects beyond the property.
Operator overloading
Operator overloadingShubham Vishwambhar The document discusses operator overloading in C++. It defines operator overloading as changing the definition of an operator so it can be applied to class objects. Only existing operators can be overloaded and the overloaded operator must have at least one user-defined type operand. An example overloads the [] operator for an Array class to allow accessing elements using A[i] syntax.
Builder pattern
Builder patternJyaasa Technologies The builder pattern is a design pattern used to separate the construction of a complex object from its representation. It allows the same construction process to create different representations. The document describes the builder pattern using the example of building computers. It defines classes for components like CPU, motherboard, drives, and their assembly into computer objects using either a general ComputerBuilder or specialized builders for desktop and laptop computers. The builder pattern participants are the builder, concrete builders, director and product, and their collaboration is described.

EuroSciPy 2019: Visual diagnostics at scale
EuroSciPy 2019: Visual diagnostics at scaleRebecca Bilbro The hunt for the most effective machine learning model is hard enough with a modest dataset, and much more so as our data grow! As we search for the optimal combination of features, algorithm, and hyperparameters, we often use tools like histograms, heatmaps, embeddings, and other plots to make our processes more informed and effective. However, large, high-dimensional datasets can prove particularly challenging. In this talk, we’ll explore a suite of visual diagnostics, investigate their strengths and weaknesses in face of increasingly big data, and consider how we can steer the machine learning process, not only purposefully but at scale!

Spring batch introduction
Spring batch introductionAlex Fernandez Spring Batch is a framework for processing large volumes of records in batch jobs. It provides reusable functions for logging, transactions, job processing statistics, and restarting or skipping jobs. Batch jobs read input data, process it, and write the output. Spring Batch jobs consist of a job with steps, an item reader to read input, an item processor to transform data, and an item writer to write output. Job repositories store metadata about job executions. Common item readers and writers include flat files, databases, and messaging systems.

Nothing beats interactive scripting for productive data exploration and rapid prototyping: grab data, run code, and iterate based on feedback. However, that story starts to break down once you need to process large datasets or expensive computations. Your local machine becomes the bottleneck, and your are left with a slow and unresponsive environment.
In this talk, we will demonstrate on live examples how you can have your cake and eat it, too, using mbrace.io, a free, open-source engine for scalable cloud programming. Using a simple programming model, you can keep working from your favorite scripting environment, and execute code interactively against a cluster on the Azure cloud. We will discuss the relevance of F# and mbrace in a data science and machine learning context, from parallelizing code and data processing in a functional style, to leveraging F# type providers to consume data or even run R packages.

Tutorial: Implementing your first Postgres extension | PGConf EU 2019 | Burak...Citus Data One of the strongest features of any database is its extensibility and PostgreSQL comes with a rich extension API. It allows you to define new functions, types, and operators. It even allows you to modify some of its core parts like planner, executor or storage engine. You read it right, you can even change the behavior of PostgreSQL planner. How cool is that?
Such freedom in extensibility created strong extension community around PostgreSQL and made way for a vast amount of extensions such as pg_stat_statements, citus, postgresql-hll and many more.
In this tutorial, we will look at how you can create your own PostgreSQL extension. We will start with more common stuff like defining new functions and types but gradually explore less known parts of the PostgreSQL's extension API like C level hooks which lets you change the behavior of planner, executor and other core parts of the PostgreSQL. We will see how to code, debug, compile and test our extension. After that, we will also look into how to package and distribute our extension for other people to use.
To get the best benefit from the tutorial, C and SQL knowledge would be beneficial. Some knowledge on PostgreSQL internals would also be useful but we will cover the necessary details, so it is not necessary.

Javaee7 jsr356-websocketJini Lee JSR 356 defines a Java API for WebSocket that allows for full-duplex communication between clients and servers over a single TCP connection. The API supports events for when the connection opens and closes, as well as sending and receiving messages. To use it, a developer creates an Endpoint class that handles events like OnOpen, OnClose, and OnMessage. They then create a dynamic web project with an HTML page containing form elements to send messages, and JavaScript code to open a WebSocket and send messages to the Endpoint for processing.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency.
This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data.
Attendees will learn:
- Consumer awareness around data brokers and what consumers are doing to limit data collection
- How businesses assess third-party vendors and their consent management operations
- Where business preparedness needs improvement
- What these trends mean for the future of privacy governance and public trust
This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.
