Brief Description: Cocreator of VisiCalc, the first PC spreadsheet

Further details:

The co-creator (with Bob Frankston) of VisiCalc, the first PC spreadsheet, Dan Franklin has been a developer, inventor, entrepreneur, and business person, with both a degree in Computer Science from MIT and an MBA from Harvard.

The idea for the electronic spreadsheet came to Franklin while he was a student at the Harvard Business School, working on his MBA degree, in the spring of 1978. Here's how he tells the story himself:

 

"Sitting in Aldrich Hall, room 108, I would daydream. 'Imagine if my calculator had a ball in its back, like a mouse...' (I had seen a mouse previously, I think in a demonstration at a conference by Doug Engelbart, and maybe the Alto). And '..imagine if I had a heads-up display, like in a fighter plane, where I could see the virtual image hanging in the air in front of me. I could just move my mouse/keyboard calculator around, punch in a few numbers, circle them to get a sum, do some calculations, and answer "10% will be fine!"' (10% was always the answer in those days when we couldn't do very complicated calculations...)

The summer of 1978, between first and second year of the MBA program, while riding a bike along a path on Martha's Vineyard, I decided that I wanted to pursue this idea and create a real product to sell after I graduated."

 

That's just what he did, though his vision became more realistic, and the heads-up display gave way to a normal screen. He and Bob Frankston decided to form a company under which to do business: Software Arts, Inc., incorporated on January 2, 1979.

VisiCalc was first shown to the regular personal computer press in a special room at the West Coast Computer Faire in San Francisco in May of 1979. The first "real" release, version 1.37, shipped in mid-October 1979. In 1985, though, Software Arts' assets were sold to Lotus Development Corporation, the creators and publishers of the 1-2-3 spreadsheet, and Lotus decided not to continue publishing VisiCalc.

"If I invented the spreadsheet today, of course I would file for a patent," Bricklin says on his incredibly candid Web site documenting the rise and fall of VisiCalc. In 1979, however, when VisiCalc was shown to the public for the first time, patents for software inventions were infrequently granted. Programs were thought to be mere mathematical algorithms, and mathematical algorithms, as laws of nature, were not patentable.

The now mainstream platform changes stemming from the first Internet boom brought many changes but didn’t really change the basic relationship between servers and the applications running on them. In fact, that was sort of the point. In his session at 18th Cloud Expo, Gordon Haff, senior cloud strategy marketing and evangelism manager at Red Hat, will discuss how today’s workloads require a new model and a new platform for development and execution. The platform must handle a wide range of rec...
When building large, cloud-based applications that operate at a high scale, it’s important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. “Fly two mistakes high” is an old adage in the radio control airplane hobby. It means, fly high enough so that if you make a mistake, you can continue flying with room to still make mistakes. In his session at 18th Cloud Expo, Lee A...

Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure ...
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
Using new techniques of information modeling, indexing, and processing, new cloud-based systems can support cloud-based workloads previously not possible for high-throughput insurance, banking, and case-based applications.

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true ...
In his keynote at 19th Cloud Expo, Sheng Liang, co-founder and CEO of Rancher Labs, discussed the technological advances and new business opportunities created by the rapid adoption of containers. With the success of Amazon Web Services (AWS) and various open source technologies used to build private clouds, cloud computing has become an essential component of IT strategy. However, users continue to face challenges in implementing clouds, as older technologies evolve and newer ones like Docker c...
