DevOps guy has to do Code Reviews and Integration and e2e Tests writing too. Because that is the only way to ensure: * Produced micro services are in high quality * Security against the hackers No automatic filters will magically help here. One super skilled programmer has to look at the fingers of less experienced colleagues. He has to be subordinate just to CEO, not CTO. Independence, protection from retaliation. Ability to deny backend updates, and there must be nothing the Programmers can do then. Lazy Programmers with attitude problems must be monitored even more. Even if "the team decided" to not do this or that, someone has to protect the company and do not let sloppy work through. Sometimes the hacker infiltrates the company, and attacks from the inside. Then such control is even more important. Many DevOps Pipelines idea is just like that, and that is what the managers often are asking for. They need Programmers to do professional high quality work. And the Programmers do not do that. How to achieve this level of control? #devops #programming #softwaredevelopment

Why is Domain-Driven Design not so popular among developers? 🤔 Despite recognizing the benefits of DDD in managing complex projects and facilitating communication between technical and non-technical team members, I observe quite limited adoption among developers 😯 Here are a few reasons why I think this happens: ▶️ Complexity and initial learning curve: DDD comes with a steep learning curve for teams not accustomed to analysis of the domain. Concepts like Bounded Context, Ubiquitous Language, and Aggregates can be overwhelming without proper guidance. ▶️ Deep domain knowledge: DDD demands a substantial understanding of the business domain, which requires developers to engage closely with domain experts. Not all developers are inclined to invest their time in acquiring deep domain knowledge, especially when they could be having fun with technologies and applying another methodology called HDD (Hype-Driven Development 😀). ▶️ Misconceptions and misapplications: Some teams attempt to adopt DDD by first diving into its technical aspects (Tactical Domain-Driven Design). This often leads to poorly executed projects that fail to deliver the expected benefits, thereby discouraging further use of DDD. ❗ At the same time, I’m not saying that DDD is beneficial for every project. For simpler applications, the overhead of implementing DDD might not justify the benefits and could lead to postponed releases. ❓ What’s Your attitude toward DDD and how do You usually encourage your colleagues to start using DDD where it’s beneficial?

"It’s harder to read code than to write it.” This is a quote for @Joel Spolsky from a blog post he wrote in 2000. In his article he talks about the single biggest mistake a software company can make being the decision to throw out the old code base and start from scratch. He reasons that the major assumption that companies make around the re-write being better than the first iteration is flawed. He also identifies that Software engineers find it easier to start from scratch rather than re-working a code base that has been working effectively and has had the bugs solved. Whilst this is an old article there are some super valuable points in it. Link is in the comments.

StackOverflow 2024 is out and Poland made it to the top 10 countries of developers participating in the survey. Interesting bits that drew my attention: - Windows and Teams are the most popular platforms right now - C# is one of the most popular programming language (ahead of Java?!) - JQuery is still much more popular than Angular (albeit far behind React).

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

Sometimes you learn things the hard(expensive) way... I'm using Polly to retry/rate limit some requests for a 3rd party API, and for some reason I've got 80 million retries in 2 days. This increased my Azure bill with ~80 EUR in just 2 days, more than I spend in one month for all resources :) It's an expensive lesson, but I'm learning lots of things and I'm going to follow up with a blog post that has more details. I'll have plenty of things to talk about, so far I've configured daily caps, alerts, telemetry sampling, I purged some data and I still have to find out what actually went wrong to prevent it in the future (probably my Polly retry policy was not configured correctly).
