John Bergmans

| HTML |

John Bergmans, owner of Bergmans Mechatronics LLC (BML), developed the first Facebook application to use the Kaazing WebSocket Gateway. This application, called EarthControl, is a good demonstration of the use of WebSockets to enable real-time, multi-user, applications within a browser, without the use of plug-ins. To support BML’s efforts to promote the use of WebSocket technology, he has also developed several other unique demo programs.

Having used TCP/IP sockets to connect devices in data acquisition and control systems, John believes that WebSockets’ TCP/IP sockets-like connectivity between browsers and servers can result in a new generation of dynamic and responsive Web-based applications.

John is an experienced speaker who has performed presentations on a range of technical topics, such as LabVIEW software programming, solid rocket motor control and laser-based instrumentation. In addition to WebSocket application research and development, BML continues to be involved in creating custom data acquisition and control software. The firm’s client base includes companies in the industrial, medical, scientific, and defense sectors.

Jeremy Osborne

| JavaScript | CSS | HTML5 | jQuery |

Jeremy never expected nor planned on becoming a hardcore programmer, much less a computer language polyglot, but that is where his varied career has taken him. Much more interested in the technical side of things, he's worked on projects from MUDs to mapping APIs to a browser front end for corporate file sharing. Jeremy likes to learn new technology by diving in, writing a lot of bugs, and then debugging everything to get a thorough understanding of how things work. There's nothing better than finding out just what a platform is capable of, and where the boundaries still exist. Jeremy's current favorite languages are JavaScript, Python, and Lua.

When he's not teaching, he's probably rock climbing with his son, writing code for that game that maybe-someday will be published, or reading yet another classic novel that he should have read in school but didn't.
