If you are curious on "Evolutionary Architecture" don't miss our .NET User Group Zürich May Meetup where we will cover the topic providing some lessons that diverge from "pure tech" talks. On this one, Maciej Jedrzejewski will explain How incremental developments in core engineering have enabled the foundations for enable software which can evolve over time along the architecture, protecting important architectural characteristics as it evolves. All while keeping it as simple as possible, maintainable and manageable in amount of complexity. Sounds interesting? ;) It is!! And even more if you have 5+ years of experience, chances are that you have lived a project that died because of complexity and lack of proper architectural vision (partial or... complete) - I've been there! So, how does it sound and all of this - for free!! Thanks Digitec Galaxus AG and Maciej Jedrzejewski!!! I am not going to miss it - and so should you... RSVP while you can, places are limited: https://lnkd.in/dmnnEGUZ Ah, we will have Food & Drink #architecture #software #evolutionaryarchitecture #KISS #DRY #easy #maintainable #resilience

https://lnkd.in/dPkaMbbe << ...Agile is not about the absence of architecture but is focused on the feedback process: planning but having immediate feedback... >> #randomthought rich of ideas and starting point to going in deep... note: microservice is more about deploy, agile is more about feedback, evolutionary architectures do not exist... in short, we return to the classic One Size Fit All is a mistake! ;-)

New 📚 Release! Master Software Architecture: A Pragmatic Guide by Maciej "MJ" Jedrzejewski Are you planning to start your software architecture journey? Or maybe you are already beginning it but feeling overwhelmed by the multitude of topics? I was in the same position years ago, which is why I wrote this software architecture book. This step-by-step guide covers all the fundamentals and key aspects of software architecture, designed to turn your confusion into confidence. It is all about real-world advice—no fluff, no unnecessary details. It's just clear, helpful content that you can use right away. Find it on Leanpub! #SoftwareArchitecture #newreleases #books #bookstan About the Book Feeling lost in the world of software architecture? This software architecture book is for you! Years ago, I felt lost when I started in software architecture. There were so many topics and issues, and I was a novice architect in the middle. I didn't know where to start building applications, what key areas to pay attention to, or how to build systems that would be able to evolve over many years. I have spent countless hours and days learning to recognize this area, and it has not been easy—knowledge was scattered throughout the Internet, books, and tutorials. Finally, mentors helped me get on the right track. That's why I decided to write this software architecture book. I want to help you navigate this complex world of hard decisions, trade-offs, and techniques that will support you in this fantastic journey. I wish you didn't have to make the same mistakes as me and give up your private life by spending many hours looking for the right information. Each step describes practically the most important aspects of software architecture. Link: https://lnkd.in/ga8WJKva

Soon, on May 8th, we're gathering at WarsawJS Meetup #114, which will take place at the Packhelp headquarters. We've prepared a truly exceptional agenda for you with three incredibly interesting lectures! 🚀 👨‍🏫 Tomasz Ducin — Back in the game: Recent Revolutionary Changes in Angular 👨‍🏫 📝 Description: Angular has been perceived as a rather complex framework by some, yet it's used massively by enterprise-scale systems. Whether we agree with the criticism or not, the framework is undergoing a monumental transformation. In recent months, Angular is experiencing a period of frequent and significant updates and - at least considering previous years of stagnation - groundbreaking changes. These include not only the features, public API and architecture, but also to the mental models that developers come up with. 👨‍🏫 Michał Trojanowski — Securing Single Page Applications Using The Token Handler Pattern 👨‍🏫 📝 Description: Single Page Applications appear simple at first sight. Web developers provide a superb user experience, and it is also relatively easy to implement token-based security in the browser. Yet this is against current best practices for browser-based apps, and security concerns can become a blocking issue. It is instead recommended to implement a Backend for Frontend (BFF), to reduce browser threats. Yet this often results in the adoption of website technologies to issue secure cookies, which can work against other web architecture goals. In this talk, I will show how a separation of web and API concerns can give you the best choices. In the talk, I will present the Token Handler pattern — Curity's variation of the Backend For Frontend approach. I will show the open-source projects we created to facilitate the implementation of the pattern. 👨‍🏫 Tobiasz Ciesielski — TailwindCSS - Why you should have it in your project? 👨‍🏫 📝 Description: Tailwind has become the most popular styling framework. More than 8 million downloads per week via npm. Why has it become so popular? What are its advantages and disadvantages? Why did we decide to migrate to tailwind in Prowly? What are the good and bad practices of using the framework? I will answer all these questions. These lectures are not only a great opportunity to gain new knowledge but also to meet other technology enthusiasts! Don't miss out on this event! 😉 Tickets are already available, so don't wait and reserve your spot now! 👇 🔖 Tickets: https://lnkd.in/dhXVXwpf See you at WarsawJS Meetup #114! 💫 #WarsawJS #Meetup #Programming #JavaScript

In the last couple of weeks, I have had many conversations with Krzysztof Przekwas and Artemi Krauczanka about the critical values of Software craftsmanship. For me: - Code should be simple and readable for all seniors and newbies in the project. - When unnecessary, try to avoid complicated patterns; maybe Kafka or MediatR is an overkill for your project. - You may have a tiny domain, or you built a simple integration to connect two systems, so it is stateless, mainly integration via REST API on the left and right site. - Remember there is a development phase and maintenance - is your code ready to be maintained? Thank you, Isaac Abraham, for the slide on the presentation (and also for the presentation about Functional Programming on .NET - The Best of Both Worlds https://lnkd.in/eiwzFUZe) PS> As a side note, I'm also in the phase of my career to merge services to optimize cost or remove a lot of unused code from the projects, and you?

Today we invite you to watch a recording of Contributed Talks from the ML in PL 2023 conference, where Piotr Januszewski talked about the "Mastering MLops at a reasonable scale at allegro".  https://lnkd.in/dEysRRKi In today's competitive e-commerce landscape, Allegro is constantly seeking ways to harness the power of Machine Learning (ML) efficiently. Central to our efforts is the challenge of building ML pipelines that can deliver personalized recommendations to our vast user base. This presentation will share our journey in mastering these pipelines at a scale that's both practical and impactful. While the world of ML offers many tools, working at a "Reasonable Scale" has its hurdles. Unlike tech giants with virtually limitless resources, most enterprises don't have the luxury of processing billions of data points daily, hiring endless talent, or leveraging infinite computing power. At Allegro, we have to be smart with our resources. We often face challenges like ensuring consistent data quality across diverse sources, managing the intricacies of deployment without the luxury of vast dedicated teams, or the need to make quick recommendations with the computing power we have available. Adapting to new ML techniques while keeping our systems efficient is a constant balancing act. This talk will dive deep into the challenges of doing ML at a reasonable scale. Through Allegro's experiences, we aim to show that with the right strategies, even mid-sized operations can achieve great ML outcomes. Piotr graduated with honors his engineering and master's degrees in computer science at the Politechnika Gdańska. He is a research engineer in the Machine Learning Research team at Allegro, where he works on the application of reinforcement learning for recommendation systems. At the same time, he is conducting research for his PhD in deep reinforcement learning at the Politechnika Gdańska. During his scientific career, he had the opportunity to, among others, cooperate with the VGG group at the University of Oxford on the "Toddler-Inspired Active Representation Learning" project and prepared materials and conducted classes on "Reinforcement Learning" at the Uniwersytet Warszawski. While working at Intel Corporation, Piotr also gained experience in implementing drivers for general-purpose computing on Intel GPUs and implementing libraries for Intel's deep learning accelerators. Privately, he is interested in science in general, and space exploration in particular. He likes hard sci-fi movies and books, post-apocalyptic, detective stories, but also space-opera novels. In his free time, he runs, bikes, snowboards, and watches the stars through his Newtonian telescope.

Quick engineering salary comparison based on the #DEVBG stats from 2023 and 2024 in the Bulgarian IT industry. Dev.bg publish yearly a summary of the Bulgarian IT engineering salaries based on the job openings offers on their platform. https://lnkd.in/dNU5MD8D (2023 stats) https://lnkd.in/dX_dxvP7 (2024 stats) Based on the population data (let's assume it's a proper representation of the real world) we can determine the following: 1. PHP should be dead but it isn't (unfortunately) as it's one of the two categories with growing salaries in all job positions and ranges. 2. The second is the full stack development with a minimum drop of 65 levas in the first MID range(2-5 years) 3. All ranges except the Senior level(5+ years of experience) have a drop in salary compared to 2023 but for some seem negligible compared to the notion in the industry that "it's going down and AI will take over the world" :) 4. We can see that seniority still counts and there is now a shift towards growth of salaries of more senior people compared to others as the market tries to regulate. 5. There is still a lot of green for a "dying" and "shrinking" industry. P.S To anyone interested I can share the excel if needed but it's quite straightforward to generate it. *Legend: Diff min Mid - difference in the minimum ranges for a category between 2023 and 2024 Diff max Mid - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen - difference in the minimum ranges for a category between 2023 and 2024 Diff max Sen - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen Median - difference in the minimum ranges based on the provided median from dev.bg for a category between 2023 and 2024 Diff max Sen Median - difference in the maximum ranges based on the provided median from dev.bg for a category between 2023 and 2024
