Why Plone Will Die
This document discusses reasons why the author believes Plone may decline or become a "CMS zombie" unless changes are made. Key points include:
- Growing developer and integrator frustration due to legacy code, complexities, lack of documentation and APIs.
- Difficult and unpredictable migrations between major Plone versions that introduce issues and costs.
- Stagnating community and market as Plone relies on aging technologies like Zope and ZODB.
The author argues Plone needs to remove legacy code, simplify architectures, introduce explicit APIs, support new databases and Python 3 to thrive in the future. A potential approach is starting from scratch with Pyramid and new components rather than continuing to build on aging foundations.

TDD - Seriously, try it! - Trójmiasto Java User Group (17th May '23)
Have you heard of TDD? Are you interested or familiar with this practice but have never been able to understand it?
Join this session to see the benefits of Test-Driven Development (TDD), understand how it works and its benefits. In a more detailed approach, we will see this way of developing software, where our code is always built guided by tests.
We will go over some history about TDD, which is the main process we must follow when we work with this mechanic and the rules that surround it. We will also list the main advantages and disadvantages that most developers who practice TDD find and whether the arguments in favour add up to more than those that subtract. Finally, we will review some good habits and practices when applying TDD and see how to do it step by step with an example of a "live" coding session with Java.
At the end of the session, I hope that you will have a wider understanding of what TDD is, what advantages it brings, why it is interesting to master it and also that you will take with you some tricks and good practices to be able to apply them in your day-to-day life when writing code

Presentation (revisited & updated) shared at JDD 2022:
https://jdd.org.pl/lecture_2022/#id=78434
Client Technical Analysis of Legacy Software and Future Replacement
The client had a legacy PHP codebase for Google Adword integration with a MySQL database that had become monolithic and difficult to modify. They wanted to replace it with a microservices architecture using Groovy, Cassandra, and separate codebases. However, this led to increased complexity, technical debt, and slower performance than the original system. It would have been better to take an incremental approach, keeping the system simple, and deferring optimizations until proven necessary by real metrics and business needs.
Vulnerability, exploit to metasploit
The document discusses developing an exploit from a vulnerability and integrating it into the Metasploit framework. It covers finding a buffer overflow vulnerability in an application called "Free MP3 CD Ripper", using tools like ImmunityDebugger and Mona.py to crash the application and gain control of EIP. It then shows using Mona.py to generate an exploit, testing it works, and submitting it to the Metasploit framework. It also provides an overview of Meterpreter and its capabilities.
UML for Aspect Oriented Design
The document discusses the need for a 3D modeling tool based on UML for aspect-oriented software development. It notes that current UML diagrams do not adequately represent the weaving of aspects into base models. A 3D tool could represent cross-cutting concerns as a third dimension to better track how aspects affect models during development. The document also provides background on aspect-oriented programming concepts like pointcuts, advices, and weaving, and examples of how aspects can be modeled in UML.
Clean Code Part III - Craftsmanship at SoCal Code Camp
When building a house, good architecture and craftsmanship together form the needed crucial elements for success. The same pattern applies to software development. As the previous sessions focused on the architectural part of software development, this session will strongly focus on often forgotten but very important areas of coding.
You will learn why naming is really difficult if done right, why coding and style guidelines are crucial, code structuring, exception handling and why other elements of coding often define the tipping point between success and failure of projects. Following the principles of software craftsmanship will allow you to end up with better maintainability and extensibility of your software and the success of the project in the end.
All 3 Clean Code presentations provide great value by themselves, but taken together are designed to offer a holistic approach to successful software creation.
Why writing Clean Code makes us more efficient
Over the lifetime of a product, maintaining the product is actually one - if not the most - expensive area(s) of the overall product costs. Writing clean code can significantly lower these costs. However, writing clean code also makes you more efficient during the initial development time and results in more stable code. You will be presented design patterns and best practices which will make you write better and more easily maintainable code, seeing code in a holistic way. You will learn how to apply them by using an existing implementation as the starting point of the presentation. Finally, patterns & practices benefits are explained.
This presentation is based on C# and Visual Studio 2010. However, the demonstrated patterns and practice can be applied to every other programming language too.
Silabus Training Reverse Engineering
This 5-day course teaches reverse engineering and malware analysis skills. It covers analyzing Windows and Linux binaries to understand program flow and perform static and dynamic analysis. Topics include disassembly, decompilation, debugging, instrumentation, and patching code. The course is intended for reverse engineers, malware analysts, security engineers, incident responders, and security professionals who need to analyze and modify binaries to securely defend against evolving threats.
TDD - Seriously, try it! - Opensouthcode
TDD involves writing tests before code to help design and develop software incrementally. It can find defects earlier and make software easier to maintain with fewer bugs. While difficult to learn, TDD seeks to build better modular code through a simple iterative process. Starting small with katas and practicing regularly, including pair programming, can help adapt to TDD's mechanics. Though challenges exist, it is worth trying TDD to potentially improve software quality and reduce costs over time.
Continuous Inspection of Code Quality: SonarQube
SonarQube is an open source platform for continuous inspection of code quality. It uses static code analysis to generate software metrics and detect issues like bugs, vulnerabilities, and code smells. These issues are tracked over time to help developers fix problems early when they are cheap to address. SonarQube integrates with development tools and pipelines to perform analysis on commits and reject code that does not meet quality standards. This provides continuous feedback on code quality and helps enforce good development practices across teams.
How to become a testing expert
This document provides guidance on how to become a testing expert. It discusses typical interview questions faced by testers and the dilemmas of both testers and management in hiring strong testing candidates. It outlines the career journey of one individual who grew from their first testing role to leadership positions. Key lessons include gaining experience over time and having the ability to find critical bugs quickly. Attributes of a testing expert are developing comprehensive testing strategies and managing the entire release process.
Introduction to TypeScript
JavaScript is a scripting language most commonly implemented in browsers that has been used for several decades now to enrich web-based applications. A a dynamically typed language that was rapidly developed for a narrow purpose, JavaScript has many nuances that make it difficult to manage in large enterprise applications. TypeScript was developed as the answer to provide a way to build large JavaScript applications without changing the language itself. TypeScript is a superset of JavaScript that provides mostly development-time features such as auto-completion, type checking, and discovery of interfaces. Learn from Wintellect principal consultant Jeremy Likness about the challenges JavaScript brings to enterprise development and how TypeScript provides an elegant solution through its implementation of types, interfaces, classes, modules and definitions.
convolutional neural networks, swift and iOS 11
Convolutional neural networks can be used for image recognition on mobile devices. The document discusses using Keras and TensorFlow to train a CNN model for digit recognition, then deploying it to iOS using CoreML. It also covers improvements to CNN models like VGGNet, Inception, ResNet, and MobileNets which use techniques like convolutions, max pooling, parallel execution and depthwise separable convolutions to improve accuracy while reducing model size and complexity. The document provides examples and code links for demos of these CNN models running image recognition tasks on mobile.
SPARKNaCl: A verified, fast cryptographic library
SPARKNaCl https://github.com/rod-chapman/SPARKNaCl is a new, freely-available, verified and fast reference implementation of the NaCl cryptographic API, based on the TweetNaCl distribution. It has a fully automated, complete and sound proof of type-safety and several key correctness properties. In addition, the code is surprisingly fast - out-performing TweetNaCl's C implementation on an Ed25519 Sign operation by a factor of 3 at all optimisation levels on a 32-bit RISC-V bare-metal machine. This talk will concentrate on how "Proof Driven Optimisation" can result in code that is both correct and fast.

Effective code reviews
It’s not easy to perform a good code review. Often done in a hurry just to get it done, it only makes things worse. People treat it as an obstacle, not a helpful thing. I am gonna tell you why code reviews are important and how they can help you maintain good quality code. I will not only tell who are the code reviews for, how to raise a useful code review, but also how to perform a good code review in the quickest time possible.
