Ravenbrook Consultant: David Jones

David Jones

Consultant.

Software engineering. Architecture, design, documentation, specification, testing, inspections, review, measurement, coding.
Standard C, inside and out, chapter and verse.
Bits and bytes. Detailed knowledge of CPU architecture. Confident at instruction level with various modern processors (chiefly IA32, PowerPC, MC68K).
Memory management and language runtime systems. Garbage collection, stacks, threads, ABI.
UNIX use, programming, and system administration: sh, awk, tar, getty, dd, od, ifconfig, tcpdump, etc.
I'm pretty much of the opinion that a good programmer can program well in any language, but the languages I know best at the moment are C, Python, Lua, awk, sh. In the past I've used perl, Lisp, Forth, Logo, ML, Modula-3, Icon, BBC Basic, Haskell. I quite like programming in assembler but rarely get the opportunity.

Currently a consultant at Ravenbrook.
1999 to 2003, Software Engineer at Zoonami Limited, a fledgling video games development company. I joined as the company formed and, along with team members who join later, undertook the development of a highly complex, configurable, innovative, and robust game development engine using C, Lua, and a tiny amount of PowerPC assembler.
1999, a brief spell as a Senior Engineer at Autonomy, a company specialising in information retrieval. I was working on their core text analysis and retrieval engine.
1994 to 1999, Software Engineer in the Memory Management Group at Harlequin Limited. The group developed world leading memory management solutions using the Memory Pool System, a unified framework that is easily adapted to customer's varied requirements, including both manual memory management and garbage collection.
