Estimations in sprints are ludicrous ?
Estimations in sprints are ludicrous ? We switched from fibonacci complexity to just plain man day. Estimating work in sprints has become a cornerstone of Agile | Scrum methodologies More and more evidence suggests it often creates more problems than it solves. On the other hand it is a nice „form” You can wrap Your work into. It is a nice template. Teams routinely face mismatches between predicted complexity and actual time investment. Exacerbated by meetings that should be an email, administrative overhead and tasks like code reviews. The Fallacy of Sprint Estimation is why complexity metrics miss but do we have anything better ? The complexity is time disconnected…

Lauers Law – why less code is better
Lauers Law – why less code is better as a very solid idea. Just remind Yourself about all those DTOs that could be a simpler one with a mapper or a dedicated if-else-tree somewhere around data transformation. It challenges developers to prioritize efficiency and elegance in their coding practices, ultimately leading to cleaner, easier to understand and more maintainable systems. The Essence of Lauer’s Law At its core, Lauer’s Law emphasizes that reducing the amount of code can lead to better outcomes. The principle suggests that if developers had twice as much time, they could create a system with half the code while maintaining or improving its quality. The idea…

Premature optimization is the root of all evil and the lesson from Duke Nukem Forever
„Premature optimization is the root of all evil.” as famously stated by Donald Knuth. This principle highlights the dangers of focusing on performance improvements too early in the development process. While optimization is essential in software engineering, prioritizing it before establishing a clear and functional design often leads to unnecessary complexity, inefficiency, and even failure. The story of Duke Nukem Forever, a sequel to a great game that was to be even better spent over 15 years in development hell. Did it make it ? Serves now as a tale of how premature optimization and feature obsession can derail a project. Someone was here obviously „Out of touch”. Knuth’s Rule:…

How to shutdown windows without updating – cdm – shutdown /s /t 0
Windows often prompts users to install pending updates during shutdown or restart. Fortunately, using the Command Prompt (cmd), you can bypass updates and shut down your system immediately. This article explains how to use the „shutdown /s /t 0” command effectively. Understanding the command The „shutdown /s /t 0” command is a simple Windows cmd instruction that forces the computer to shut down instantly without processing updates. Here’s what each parameter means: Command Description shutdown /s Shuts down the computer after a default 30-second delay (can be modified with /t). shutdown /s /t 0 Shuts down the computer immediately (similar to /p). shutdown /f Forces running applications to close without…

Learning by writing essays
Learning by writing essays is a very old technique. First you gather all the information about a given subject and then You write essays about given topics. It can be a powerful educational tool which will enhance learning and comprehension. By process of researching and composing essays, You can deepen understanding and develop essential skills. https://www.researchgate.net/publication/249738752_The_Origins_of_Writing_in_the_Disciplines Personly this is how i learned photography, first consume the knowledge, read, watch, listen and then write a blog post ! Worked like a charm and was easy to do cause of small bits and pieces of the topics i have chosen to write about. There is no need to make it 'big’. You…

Feynman technique
The Feynman Technique is a powerful learning method developed by Nobel Prize-winning physicist Richard Feynman. It emphasizes deep understanding through teaching, simplification, and systematic review. Here’s a detailed overview of its four key steps: Steps of the Feynman Technique Benefits of the Feynman Technique Summary Kinda pair programming or other knowledge sharing session. In a day to day work as a developer You might use the Feynman Technique to transform the learning process into an interactive experience. Discussion is highly encouraged ! ( As always ) This technique emphasizes that true understanding comes from the ability to explain concepts in simple terms, or just simply enough. This makes it applicable…

Chestertone`s Fence in coding and not only
The Chestertone`s Fence in coding is the principle named after the writer G.K. Chesterton. Serves as a critical reminder in programming and software development: before removing or altering existing code, one must understand why it was implemented in the first place. This principle is universal for life. Emphasizes the importance of historical context and the potential consequences of change, especially a quick and fast one. Urging developers to approach modifications with caution and respect for prior decisions. Even if they are unknown or seem meaningless. Understanding the Chesterton`s Fence Chesterton`s Fence principle, at its core, suggests that every piece of code, no matter how outdated or unnecessary it may seem,…

A Philosophy of Software Design by John Ousterhout – review
A Philosophy of Software Design by John Ousterhout is a great book. Period. I would say that it is a great additional to reading Clean Code. Clean code in my opinion is dry and very… strict ? Not much room to fiddle around with rules set by Uncle Bob the Guardian of the Clean Code. John Ousterhout provides us with a more kind and flexible approach without strict, dry rules to follow. Since the book was wrote by a professor at Stanford that had classes it might get a bit technical when John goes through the different code sets but it does print a better picture of the whole problem.…
