Learn Elixir Programming is a complete learning app designed for beginners, students, developers, and programmers who want to build strong skills in functional programming and modern backend development. Whether you are new to Elixir, learning functional programming, preparing for interviews, or improving your backend development knowledge, this app gives you a clear and structured learning path. The app explains Elixir concepts in a simple and practical way, helping you understand how to write clean, scalable, and maintainable code. Elixir is a dynamic, functional language designed for building scalable and maintainable applications. It is built on top of Erlang. Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain. Elixir is a functional, dynamic language built on top of Erlang and the Erlang VM. Erlang is a language that was originally written in 1986 by Ericsson to help solve telephony problems like distribution, fault-tolerance, and concurrency. Elixir, written by José Valim, extends Erlang and provides a friendlier syntax into the Erlang VM. It does this while keeping the performance of the same level as Erlang. What you will learn Elixir basics and syntax Variables and data types Pattern matching Functions Modules Lists and tuples Maps and structs Recursion Control flow Pipelines Anonymous functions Functional programming concepts Processes Concurrency basics Error handling Mix projects OTP basics Phoenix framework basics Common interview questions Practical coding examples Why choose this app Step by step Elixir lessons Beginner friendly explanations Clean and simple learning experience Practical code examples Quizzes to test your knowledge Progress tracking for your learning journey Useful for students and self learners Helpful for interview preparation Great for backend developers Perfect for quick revision Elixir is widely used for scalable web applications, real time systems, distributed applications, backend development, and reliable software systems. With this app, you can build a strong foundation and improve your confidence in modern functional programming. Learn at your own pace and master Elixir anytime.

Dec Opcodes – DEC Architecture Reference Before the microprocessor, there was DEC. The minicomputers built by Digital Equipment Corporation didn't just advance computing - they defined it. Unix was born on a PDP-7. Spacewar! ran on a PDP-1. The field of Artificial Intelligence was born on the PDP-10. The VAX powered universities and research labs worldwide for a generation. DecOpcodes puts the complete instruction sets of these legendary machines in your pocket. Five iconic architectures covered: PDP-1 (1960) · PDP-8 (1965) · PDP-10 (1966) · PDP-11 (1970) · VAX (1977) For every instruction:  • Full description of what the instruction does  • Octal and hex encoding  • Flags affected  • Addressing modes, word count, and cycle counts  • Assembly code examples and implementation notes But there is a lot more than just dry opcodes:  • Complete system specifications and register architecture  • Historical context and cultural impact  • Archival photographs - front panels, system cabinets, and more  • Notable installations and the systems they powered  • Architecture variants and successors • Interactive lessons on assembly language and console operations (ideal if you have an PiDP emulator) Built for exploration:  • Search across all systems instantly • A simple assembler for PDP-1, -8 and -11 code • Filter by instruction category  • Sort alphabetically or by category • Favorite instructions for quick reference Beautifully designed:  • System-specific accent colours  • Five themes including Terminal green and Blinkenlights orange  • Full Dark Mode support From the 18-bit simplicity of the PDP-1 to the 32-bit sophistication of the VAX, DecOpcodes is a fascinating and interactive journey through the machines that made modern computing possible. All features are free and unlocked. If you like the app you can always leave a nice review or tip the developer!
