Software History-Why
Book on software history
Many current students have little knowledge of SW history
Get dribs and drabs in some courses and textbooks
Missing the big picture on software’s evolution
There’s a need to know
The focus is on what technology students need to know

Issues Addressed
11/16/2015Software History10
No existing textbook on software technical history
Students are left with a sea of bits and pieces
My foci:
Understanding software base and its evolution
Applying learnings to future systems
![Page 11: CS1000 Software Historynilufer/classes/cs1000/2015... · CS1000 Software History Kim Tracy kwtracy@mtu.edu 1 Software History 11/16/2015 Mark I, Grace Hopper Tape for Problem “L”,](https://reader030.fdocuments.in/reader030/viewer/2022040304/5e9cbd58e722af28583335e8/html5/thumbnails/11.jpg)
What has happened to make a software
history necessary?
11/16/2015Software History11
To manage complexity, we’ve increased the levels of
abstraction
Students often learn and use only the highest levels
We’re rarely teaching a lot of the lower levels (file
systems, DBMS internals, OS internals, Assembler, etc.)
We’ve rapidly specialized
We’ve got over 60 years of history

Historiographical method
11/16/2015Software History12
Software is a technology
Using a “domain” and “sub-domain” approach*
Focus on core domains: operating systems, programming environments, databases, networking, etc.
Other concepts: significant events, communities of practice, standard engineering
Importance of primary sources
Software is an unusual technology
Very loosely based on physical phenomena
More like mathematics in building on previous abstractions/results
Why haven’t historians of technology done this?
* As per a combined approach of Basalla, Arthur and Constant.

Book Structure
11/16/2015Software History15
Use a broad technical evolution with significant events
and then include deep dives into:
Chapters by software technology domain
Important examples of source code
Failures and learnings
Other case studies

Summary
11/16/2015Software History23
Software history’s time has come
Student’s have a need to know
No cohesive, digestible view
Losing software pioneers
Gives students a picture of the overall evolution of SW
ability to reason about trends and future possibilities
