Working on legacy applications is very demanding, because with legacy comes the so-called technical debt. There are patterns to try and reduce this debt. In this workshop, we will propose some of those patterns, and see how third party libraries like our mORMot 2 Open Source framework could help in this evolutionary process. The main idea is to not reinvent the wheel, but iterate over the existing solution to make it expandable, not expendable. Depending on the audience, we will adapt and focus on your actual needs and questions.]]>

The One Billion Row Challenge (1BRC) is a fun exploration of how far modern Object Pascal can be pushed for aggregating one billion rows from a text file, more precisely a 16GB csv file. During two months of 2024, more than a dozen entries were proposed to fulfill this challenge. In this session, we will show our own proposals, which ended to be the fastest, even faster than the winners of the original 1BRC in the Java world. You will certainly learn something about CPU caches, syscalls, branchless coding, parallel computing, and eventually be able to brag how modern pascal is still in the race!]]>

The TFB challenge is a performance comparison of many web app platforms, exercising JSON, database, ORM, HTML templates, all over HTTP. It compares the best frameworks written in C++, Rust, Go, JS, Java, C# and now Pascal thanks to mORMot. In this session, we will look and compare the source code of some frameworks samples, to distinguish their typical philosophy. We will see how modern Object Pascal is still relevant, and propose some ideas for the future of the language.]]>

The most powerful way of writing REST services is to define them via interfaces, then let the SOA/REST framework do all the routing, data marshalling and communication behind the scenes. One distinctive feature of mORMot is to define a method parameter as a notification interface, and let the server call back the client when needed, as with regular Delphi code. This session will present the benefit of defining REST services using interfaces, and how WebSockets can offer real-time notifications into your rich Delphi client applications.]]>

The OpenSource mORMot framework has a strong set of cryptography features. It offers symmetric cryptography with hashing and encryption, together with asymmetric cryptography via private/public key pairs. Its optimized pascal and assembly engines can be embedded into your executable, but you could also call an external OpenSSL library if needed. This session will present mormot.crypt.* units, and apply them to some use cases, from low-level algorithms to high-level JWT or file encryption and signing.]]>

During the continuous mORMot refactoring, some core part of the framework was rewritten. In this session, we propose a journey to a refactoring of a single loop. It will take us from a na誰ve but working approach, to a 10 times faster Pascal rewrite, and then introduce how SSE2 and AVX2 assembly could boost the process even further to reach more than 30 times improvement! No previous knowledge of assembly is needed: we will try to introduce how modern CPUs work, and will have some fun with algorithms and SIMD parallelism.]]>

It will create a network of user-generated content, not only connected around people or topics, but unleashing some reference text material: literature, law, science, religion you name it. We will discuss proper KDD architecture, data structures, and associated microservices, using mORMots ORM and SOA as toolbox. The code of this new social media system will be disclosed under a GPL agreement, and running on production for years to come. It should be able to scale from a few users to worldwide adoption. ]]>

This EKON 22 conference is about high performance on servers, written in the object pascal (Delphi / FPC) language. Profiling should be the first step to avoid premature optimization, which is the root of all evil (Knuth). But when some bottlenecks are identified, we introduce some simple architecture patterns (like caching or microservices), data structures and algorithms to make process actually faster, with minimal refactoring.
