Slick (part of the Typesafe stack) is a modern database query and access library for Scala, based on functional principles. It allows you to write queries as if you are working with regular Scala collections.
In this presentation we’ll have a deep dive into how you can use this library in real projects. How to map your tables and queries to structured objects, how to create more advanced queries with multiple joins, how to setup integration tests against an in-memory database and how you can integrate Slick with the Play Framework are all questions which will have been answered at the end of this presentation.

GlueCon 2015 - Publish your SQL data as web APIsRestlet
With increasing demand for universal access to data, web APIs are an easy way to provide data sets to partners, customers, or even the entire world! For many businesses, bridging the gap between SQL databases and web APIs is not as easy as it looks. There are however simple ways to create data-driven APIs without programming. We’ll provide an overview of the technical challenges and how to overcome them. We’ll also show example deployments of APIs that provide access to SQL data.
Tear It Down, Build It Back Up: Empowering Developers with Amazon CloudFormationJames Andrew Vaughn
As a product grows, and the infrastructure becomes more complex, the Operations team traditionally shoulders the burden of maintaining this infrastructure while deploying code from Software Engineers. Code is sometimes given to Operations with little to no information regarding how it should run or what the criteria for successful deployment is. This is not due to lack of caring, Software Engineers often lack the context themselves to provide production deployment instructions. To Software Engineers, production can be like a walled off city, filled with pathways and rooms not to be explored, guarded by Operations.
This presentation aims to provide a solution to this problem. We will address how the traditional separation of Operations and Software Engineers slows innovation, and redefine their relationship -- blending responsibilities. We will examine the transition of two real teams, an Operations team and Engineering team, from complete isolation, to closer environments through virtual machines, to one cloud environment shared by all and managed with CloudFormation.

LINQ stands for Language Integrated Query.
A query is an expression that retrieves data from a data source or database.
Retrieve data from different data source like an object collection, sql server database, xml & web service etc.
LINQ Syntax like- var students = dbContext.Students.ToList();
LINQ
The acronym LINQ stands for Language Integrated Query. Microsoft’s query language is fully integrated and offers easy data access from in-memory objects, databases, XML documents, and many more. It is through a set of extensions, LINQ ably integrates queries in C# and Visual Basic. This tutorial offers a complete insight into LINQ with ample examples and coding. The entire tutorial is divided into various topics with subtopics that a beginner can be able to move gradually to more complex topics of LINQ.
NoSQL, as many of you may already know, is basically a database used to manage huge sets of unstructured data, where in the data is not stored in tabular relations like relational databases. Most of the currently existing Relational Databases have failed in solving some of the complex modern problems like:
• Continuously changing nature of data - structured, semi-structured, unstructured and polymorphic data.
• Applications now serve millions of users in different geo-locations, in different timezones and have to be up and running all the time, with data integrity maintained
• Applications are becoming more distributed with many moving towards cloud computing.
NoSQL plays a vital role in an enterprise application which needs to access and analyze a massive set of data that is being made available on multiple virtual servers (remote based) in the cloud infrastructure and mainly when the data set is not structured. Hence, the NoSQL database is designed to overcome the Performance, Scalability, Data Modelling and Distribution limitations that are seen in the Relational Databases.
Microsoft is working hard to modernize the .NET Platform. There are great new frameworks and tools coming, such as .NET Core and ASP.NET Core. The amount of new things is overwhelming, with multiple .NET Platforms (.NET Framework, Unified Windows Platform, .NET Core), multiple runtimes (CoreCLR, CLR, CoreRT), multiple compilers (Roslyn, RyuJIT, .NET Native and LLILC) and much more. This session will bring you up to speed on all this new Microsoft technology, focusing on .NET Core.
But, we will also take a look at the first framework implementation on top op .NET Core for the Web: ASP.NET Core 1.0. You will learn about ASP.NET Core 1.0 and how it is different from ASP.NET 4.6. This will include Visual Studio 2015 support, cross-platform ASP.NET Core and command-line tooling for working with ASP.NET Core and .NET Core projects.
After this session you know where Microsoft is heading in the near future. Be prepared for a new .NET Platform.
Presentation for Stichting DotNed in 2015:
Microsoft neemt ASP.NET op de schop. Het web applicatie framework uit .NET 1.0 wordt grotendeels herschreven om te voldoen aan de eisen die men tegenwoordig stelt aan het realiseren van een moderne web applicatie. Deze sessie kijken we naar de nieuwe opzet van ASP.NET. We zien hoe Microsoft daarmee een cloud geoptimaliseerd, cross-platform framework creeert, dat zij zelf sneller kunnen laten evolueren door kortere release cycles. Dit alles betekent wel dat ASP.NET anders is geworden. In deze sessie leer je daarom ook wat er is veranderd, hoe je aan de slag gaat en waarom ASP.NET vNext een revolutionaire stap is in Microsoft's framework.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
2. Overview of Data Access
(Chapter 8)
• 99.99% of apps involve some type of data
• We can use data bound controls to
generate our web application’s UI

7. What is LINQ?
• LINQ stands for Language Integrated
Query
• A general purpose query facility to
query relational data, XML data,
objects/collections.
• New in .Net Framework 3.5 – must
target .Net Framework 3.5
• Based on standard query operators
• LINQ query syntax resembles
backwards SQL statements

9. Benefits of Using LINQ
• May not need to build an entire DAL
(data access layer)
• Much easier to query XML – don’t
have to use Xpath
• Work with data in a consistent way –
whether it is SQL Server data, XML
data, ADO .Net dataset, an object
collection, or data in memory
• Offers compile time checking,
autocompletion, and Intellisense
10. New C# Language Features
that Support LINQ p902
• Automatic properties
• Initializers
• Type Inference
• Anonymous types
11. Three Parts of a LINQ Query
• Obtain the data source
• Create the query
• Execute the query
12. What’s a DataContext?
• The DataContext is the source of all
entities mapped over a database
connection
• It tracks changes that you made to all
retrieved entities and maintains an
"identity cache" that guarantees that
entities retrieved more than one time are
represented by using the same object
instance.
