Walter Bright is the creator and first implementer of the D programming language and has implemented compilers for several other languages. He's an expert in all areas of compiler technology, including front ends, optimizers, code generation, interpreter engines and runtime libraries. Walter regularly writes articles about compilers and programming, is known for engaging and informative presentations, and provides training in compiler development techniques. Many are surprised to discover that Walter is also the creator of the wargame Empire, which is still popular today over 30 years after its debut.

Andrei Alexandrescu coined the colloquial term "modern C++" (adapted from his award-winning book Modern C++ Design), used today to describe a collection of important C++ styles and idioms. He is also the coauthor (with Herb Sutter) of C++ Coding Standards and the author of The D Programming Language book. With Walter Bright, Andrei co-designed many important features of D and authored a large part of D's standard library. His research on Machine Learning and Natural Language Processing completes a broad spectrum of expertise. Andrei holds a Ph.D. in Computer Science from the University of Washington and a B.Sc. in Electrical Engineering from University "Politehnica" Bucharest. He works with the D Language Foundation.

Scott Meyers started programming in 1971, and he started teaching programming in 1972. He’s best known for his Effective C++ books, but he’s also worked on constraint expression for programming languages, program representations in development environments, software simulations of bacteriophage lambda, general principles for improving software quality, and the effective presentation of technical information. In 2009, he received the Dr. Dobb’s Excellence in Programming Award, and in 2014, an online poll likened his hair style to that of the cartoon character, He-Man.

Johan Engelen is one of the core LDC developers. He is also a D compiler consultant for Weka.io (probably the largest industrial single-executable D codebase) and maintains and adds features to their fork of LDC. While working on LDC, he often studies the compiler output IR and assembly. To aid this, he helped setting up LDC at d.godbolt.org. Examples of his recent contributions to LDC related to optimization are @fastmath, link-time optimization (LTO) and profile-guided optimization (PGO).

Johan (PhD Electrical Engineering) is assistant professor in the Robotics and Mechatronics (RAM) group at the University of Twente, the Netherlands. In his spare time he has contributed large amounts of work to the open source projects LDC and Inkscape.

I am a generalist programmer, with a good grasp of computer architecture and distributed systems. I started using D early in its life, but I became especially interested in the language when ranges and range-based algorithms were introduced. These STL-inspired facilities made significant progress on a promise that object-oriented programming failed to deliver, and which the STL only delivered to a limited extent: the design and employment of reusable components.

By training I am a software engineer. By night I wear a cape and dabble in hardware design. A few years ago I bought an FPGA and taught myself hardware design. While FPGAs are super exciting, I found that VHDL and Verilog can sap all the joy out of hardware design. As part of my search for alternatives I found Chisel. While Chisel aimed to do for hardware what D tries to achieve with its design by introspection (create generic yet efficient building blocks), I found the usability of Chisel to suffer due to its life as Scala DSL.

I have stated before that "whenever possible I choose D for the task -- even for hardware design". This is my attempt to make good on that promise; to bring the Chisel model of hardware design to D, and all the modeling power it has to offer.

He likes learning new technologies and strengthening his current knowledge. He is passionate about computer science because we get to think about and tackle problems that we encounter on a daily basis and we are able to find solutions that help other people. His previous experience includes distributed systems and parallel programming, operating systems, basic kernel development, open-source software and basic Android programming. He is a Linux fan, a command line addict and a vim enthusiast. He hopes that through his work he will be able to help and improve the D language, which he is becoming so fond of.

Bastiaan Veelo came to know about D shortly after it was released some sixteen years ago, while trying to write a flex/bison parser for C++ to pretty-print his code in a literate programming report. He found out the hard way that C++ is a pain to parse, and as D advertised with being developed with fast and easy parsing in mind, it quickly got his attention. Since then, he has been following D’s evolution continuously, without the opportunity to use the language professionally. Recently, he has been investing time to change that and help create that opportunity, which has led him to work on parsers once again — this time in D.

Bastiaan is the lead developer of a specialised program for the computer aided geometric design of ship hulls called Fairway, for the company SARC in the Netherlands. He holds a B.Eng. in naval architecture from the Haarlem Polytechnic, an M.Sc. in marine technology and a Ph.D. in mechanical engineering from NTNU, the Norwegian University of Science and Technology.

As a person, some might say he likes squirrels just a bit too much but they’re objectively wrong. We don’t have squirrels in Australia.

I am a student at Murdoch University, Western Australia, studying for my BEng (Hons)/BSc in Industrial Computer Systems & Instrumentation and Control / Molecular Biology & Biomed. I am currently doing my honours thesis on low cost Electroluminescence imaging of solar cells. I have been using D for 5 years for odd jobs and number bashing.
