Diomidis Spinellis is a Professor in the Department of Management Science and Technology at the Athens University of Economics and Business, Greece. His research interests include software engineering, programming languages, internet information systems, computer security, and intelligent optimization methods. He holds an MEng in Software Engineering and a PhD in Computer Science both from Imperial College London.

Spinellis is a FreeBSD committer and the author of many open-source software packages, libraries, and tools. His implementation of the Unix sed stream editor is part of all BSD Unix distributions and Apple's Mac OS X. Other tools he has developed include the UMLGraph declarative UML drawing engine, the ckjm tool for calculating Chidamber and Kemerer object-oriented metrics in large Java programs, the Outwit suite for integrating Windows features with command-line tools, the fileprune backup file management facility, and the socketpipe network plumbing utility. In 2004 he adopted and has since been maintaining and enhancing the popular bib2xhtml BibTeX bibliography format to HTML converter. Currently he is also serving as the scientific coordinator of the EU-funded SQO-OSS cooperative research project, a software quality observatory for open-source software.

Spinellis has published two books in Addison-Wesley's "Effective Programming Series": in 2004 Code Reading: the Open Source Perspective, which received a Software Development Productivity Award in 2004 and has been translated into six other languages, and in 2006 Code Quality: the Open Source Perspective, which also received a Software Development Productivity Award in 2007. Both books use hundreds of examples from large open source systems, like the BSD Unix operating system, the Apache Web server, and the HSQLDB Java database engine, to demonstrate how developers can comprehend, maintain, and evaluate existing software code. Spinellis has also published more than 100 technical papers in journals and refereed conference proceedings. The article A Survey of Peer-to-Peer Content Distribution Technologies he co-authored in 2004 appeared in the list of ACM's most downloaded digital library articles throughout 2005 and 2006. He is a member of the editorial board of IEEE Software, authoring the regular Tools of the Trade column, and Springer's Journal in Computer Virology.

Spinellis is a member of the ACM, the IEEE, the Usenix Association, the Greek Computer Society, the Technical Chamber of Greece, a founding member of the Greek Internet User's Society, and an active Wikipedian. He is four times winner of the International Obfuscated C Code Contest and a member of the crew listed in the Usenix Association 1993 Lifetime Achievement Award.

Kyoto’s Nasty 22% City-Bike Hill Climb

May 24 2015

距離125mで高度上昇26m、22%の坂を頑張りました。 I went out for a long bike in the mountains of northern Kyoto on Saturday, and after 120km (75mi) of tough ups and pleasant downs with friends (that I'll write about separately), I made an attempt at a hill so steep that its name on Strava is "Nasty". It's… read more

Why are Eight Bits Enough for Deep Neural Networks?

May 23 2015

Picture by Retronator Deep learning is a very weird technology. It evolved over decades on a very different track than the mainstream of AI, kept alive by the efforts of a handful of believers. When I started using it a few years ago, it reminded me of the first time… read more

"Spinellis and his co-editor Georgios Gousios have done a good job of selecting interesting essayists and of putting their works together into a collection that feels solid. Reading it will certainly make you think more about your own project's architecture...Whether it's something you're building on the weekends or on the job, Beautiful Architecture will certainly do your code base good."
