Resume/CV for Dan Lyke
I hate to do this, because I really do think people should host their own stuff, but https://github.com/danlyke (even though all that code could use a clean-up... all code can).
Skills
Recent languages include Objective-C, C++, Perl, C#, SQL (mainly PostgreSQL and MySQL), and a little bit of boilerplate JavaScript. Recent environments include Linux (both embedded, Ubuntu and SL), Microsoft Windows & .NET, Macintosh OS/X, and iOS. Have worked with Atmel AVR assembly, with Python, x86/MMX assembly, Java, PL/I, a few variants of Pascal, a BASIC or two, xBase, and several assembly languages.
Other buzzwords: I've worked with XML, XSLT, CSS and JSON; written programs which use HTTP, NNTP and SMTP protocols and OpenGL, DirectX and Glide, and RenderMan APIs; am familiar with XML-RPC and REST, and have used SOAP; when necessary, I've designed circuits and built hardware. I've also played with the basics of geography, datums, projections and the like.
Work History
July 2018 - Present: MeshOS
MacOS based shared zoomable canvas web browser product, with dreams of eventually being a full platform, that is just reaching shipping stage. Much interfacing with AppKit, various web technologies, and all sorts of threading and distributed database (Firebase) issues.
June 2016 - July 2018: SpeedGauge.net
Managing a map of the world and a reverse geocoding system to do vehicle telemetry analysis for fleet safety. Java+Ansible+AWS+Postgres/PostGIS, results included US Patent #11692845.
February 2012 - June 2016: Sonic.net
Developing internal business process systems in Perl, MySQL and an internal RPC protocol, on Linux. The systems are incredibly complex, with processes that run for days, include lots of humans in those processes, across many different (mostly in-house) applications. Some coordination with external SOAP APIs.
Responsible for the equipment rental tracking system, currently refactoring large portions of the accounting/bookkeeping system.
April 2008 - Flutterby.net, my consulting company
Took a few side-projects full-time. Projects have included: research for transportation policy reports presented to federal agencies; firmware on ARM, AVR and embedded Linux on ARM platforms; a distributed back-end for information sharing for an astronomical imaging application (still in development); software on a variety of user devices from C# .NET on Windows to C++ and Objective-C on the iPad and OS/X Cocoa environments.
April 2005-April 2008: Digital Fish
Worked on Reflex, an animation system for movie studios. Added features and optimized expression graph evaluation, did some work on a Maya export plugin.
July 2004-April 2005
Worked on a photo manager to that understood geography. Couldn't figure out how to turn it into a business. Assorted other work, including some demonstrations for using game platforms and GPS enabled handheld devices for tactical awareness systems in urban combat.
Somewhere between here and Flutterby.net I also wrote some YADIS conformance tests for VeriSign. YADIS is the discovery portion of OpenID.
June 2002-July 2004: Alvanon
(fit mannequins and products for the fashion industry)
Developed hardware and software for the Garment Visualization System, a tool for remote garment fit verification and evaluation. Implemented motion control, including circuits, mechanical drawings and communications with overseas factories, and camera control for manipulating and photographing mannequins. Worked with C# based .NET applications, embedded Linux, and Atmel AVR.
June 2001-June 2002: Gracenote
(the CDDB music database people)
Worked on "Service 3", the XML based distributed database replacement for Oracle for CDDB. System is written in heavily threaded C, answering millions of authenticated queries per day. I wrote the multi-threaded distributed dispatching system that's the core of every message that passes through the system, and the Perl that builds C code to to simplify using XML.
May 2001: exploratory coding for a bio-informatics startup
Software for examining datasets such as those derived from gene expression, operations like principal component analysis (PCA) to find vectors of most import in thousands dimensional spaces.
February 2000-April 2001: Coyote Grits LLC
(contract software developers)
Founding partner in a software contracting company creating solutions for a diverse set of clients. Managed and coded on projects which mostly involved Perl on Apache or CGI, with forays into Java, TCLOAD (for VeriFone TRANZ credit card processing). Did training and mentoring to turn relatively junior people into productive assets during that time of extreme worker shortages.
August 1995-January 2000: Pixar Animation Studios
("Toy Story", "A Bug's Life",...)
Graphics R&D/RenderMan Group: Implemented a new internal API for image output which allowed arbitrary channels (more than just RGBAZ), quick implementation of new formats, different regions of images coming from diverse remote sources. Ported RenderMan to Windows NT.
RAPIX Real Time Rendering group: We developed a cross-platform (Windows, SGI, Mac) framework for real-time 3d rendering and scene description. The framework mixed renderers like OpenGL and Glide with home-grown ones, one built for detailed characters gave us extremely high triangle rates (500k/sec on a P133). I wrote Windows code, implemented the feudal priority tree algorithm, and used MMX assembly language to get those extreme triangle rates.
Interactive Group: Wrote the QuickTime for Windows codecs for Pixar's proprietary "PIX" video system, and helped develop extensions to that format, some audio filtering, some installers and uninstallers, and a few of the scenes and segments of the best selling CD-ROM based games "Toy Story Animated Story Book" and "Toy Story Activity Center".
August 1993-August 1995: Hacker for Hire
(contract software development)
Wrote contract code in C, C++, Borland Paradox and xBase variants, with a few Novell installations, a little work with embedded controllers, and hardware and software maintenance. Highlights include research for a terrain displaying game engine for a startup, (discussion of which on comp.graphics.algorithms lead to my job at Pixar), an HTML browser for the TBBS/TDBS online system, a carpet design system interface to a tufting machine controller.
August 1993-August 1995: Chattanooga On-line
(a successful regional ISP)
Founded and helped run Chattanooga On-line (chattanooga.net), a regional Internet service provider. I was the heavy technical person in a team of two which implemented and ran a full-service ISP: TCP/IP, Smail (for SMTP and UUCP mail), INN (for NNTP news), NCSA HTTPD (an early web server), RADIUS (for dial-up user authentication) and BIND (for name services).
July 1989-July 1993: Signal Data
(software and data services for health insurance agents)
Lead programmer for Signal Data Inc. of Chattanooga, TN for their GROUPS4 software. My accomplishments include: Writing and maintaining 250,000 lines of C code and coordinating internals in a multiprogrammer project that exceeded 400,000 lines of code, a compacting handle based heap manager, rebuilding and handling b-Tree indexes independent of the commercial database manager (C-Tree), a test system that allowed replay of multiplexed user events and database accesses from multiple workstations to debug potential multi-user issues, and a windowing system which allowed high speed no flicker updates of partially obscured windows, and making the whole thing run in 490k of memory on a 4.77MHz 8086.
Additional Personal Projects
Co-founder of Petaluma Urban Chat, a non-profit focused on education around housing to meet community needs, non-automobile mobility, climate change adaptation, and sustainable municipal finance. We put on the Know Before You Grow series of forums.
I'm a Modern Western Square Dance caller, including co-hosting 100 episodes of online newer caller education forums with calling legend Don Beck. I'm co-author of the open source SquareDesk music and information management program.
Ongoing hacking on Flutterby.com weblog CMS, written in Perl and PostgreSQL under the Apache and mod_perl environment, and features multiple contributors, automated topic assignment, HTTP and NNTP interfaces, along with assorted XML-RPC web services.
Assorted other projects, from an irrigation controller to a static site generator are out there, alas with no other users yet.
