LeetCode Book
Comprehensive study guide for coding interviews
...Explanations are concise but intentional, highlighting why a pattern fits, how to reason about boundary cases, and the time/space trade-offs. Many entries include template code and “swap-in” variations, helping you recognize how the same technique adapts across similar problems. The book also emphasizes problem-solving habits like deriving invariants, choosing appropriate data structures, and verifying with small counterexamples. It’s suitable for newcomers building fundamentals and for experienced engineers polishing timing and correctness under interview pressure. -

Re-learning Java Design Patterns
Design-pattern learning project based on "Relearning Java Design"
...Instead of presenting design patterns as abstract theory, it teaches them through practical internet business scenarios. The repository includes examples drawn from transactions, marketing, flash-sale systems, middleware, source-code analysis, and other real development contexts. Its goal is to show how design patterns solve concrete engineering problems rather than simply naming pattern structures. The project is useful for Java developers who want to improve architecture thinking, code extensibility, and implementation discipline. It also serves as a companion codebase for readers who want to study each pattern through runnable Java examples. -

UMHDL
Integrated Development Environment (IDE) for learning HDL
...The aim for the UMHDL development was to have a graphical application that allows learning the VHDL language without licensing restrictions (using some existing open-source tools) and requiring few resources. So, the interface developed acts as a front-end that allows writing code (with syntax highlighting), invokes an external VHDL compiler and simulator (such as GHDL), and displays the result of the simulation graphically as waveforms (invoking to GTKWave). -
