Programming Erlang

Mehr zum Buch

Erlang addresses a critical challenge for developers: creating reliable, concurrent, high-performance systems. It is widely adopted by companies needing efficient and scalable applications. As Moore's Law shifts focus from faster processors to multi-core devices, the importance of concurrent programming becomes evident. Without concurrency, programs will only utilize a single processor, leading to perceptions of sluggish performance. Erlang is specifically designed for developing highly parallel, distributed, and fault-tolerant systems, having been successfully used for years in commercial applications that require minimal failures. Its programs efficiently leverage multi-core computers, allowing them to run significantly faster on systems with multiple cores without requiring code changes. By integrating concepts from functional programming with fault-tolerance techniques, Erlang emerges as a robust language for the future's massively parallel, networked applications. This book introduces Erlang and functional programming in a pragmatic style, authored by Joe Armstrong, a co-creator of Erlang. It features example code for readers to build upon and includes the complete source code for two engaging applications. Invest in learning Erlang to enhance your development skills and meet the demands of modern computing.
