3. Early History: The First Programmer
• Jacquard loom of early 1800s
– Translated card patterns into cloth designs
• Charles Babbage’s analytical engine (1830s & 40s)
Programs were cards with data and operations
• Ada Lovelace – first programmer
“The engine can arrange and combine its numerical quantities
exactly as if they were letters or any other general symbols; And in
fact might bring out its results in algebraic notation, were provision
made.”

5. The 1940s: Von Neumann and Zuse
John Von Neumann
led a team that built
computers with stored
programs and a central
processor ENIAC.
6. Konrad Zuse and Plankalkul
Konrad Zuse began work on Plankalkul (plan
calculus), the first algorithmic programming
language, with an aim of creating the theoretical
preconditions for the formulation of problems
of a general nature.
Seven years earlier, Zuse had developed and
built the world's first binary digital computer,
the Z1. He completed the first fully functional
program-controlled electromechanical digital
computer, the Z3, in 1941.
Only the Z4, the most sophisticated of his
creations, survived World War II.
7. Machine Code (1940’s)
•Initial computers were programmed in raw machine code.
•These were entirely numeric.
•What was wrong with using machine code? Everything!
•Poor readability
•Poor modifiability
•Expression coding was tedious
•Inherit deficiencies of hardware, e.g., no indexing or floating point
numbers
8. Pseudocodes (1949)
•Short Code or SHORTCODE - John Mauchly, 1949.
•Pseudocode interpreter for math problems, on Eckert
and Mauchly’s BINAC and later on UNIVAC I and II.
•Possibly the first attempt at a higher level language.
•Expressions were coded, left to right
9. More Pseudocodes
Speed coding; 1953-4
• A pseudocode interpreter for math on IBM 701, IBM 650.
• Developed by John Backus
• Pseudo ops for arithmetic and math functions
• Conditional and unconditional branching
• Auto increment registers for array access
• Slow but still dominated by slowness of s/w math
• Interpreter left only 700 words left for user program
Laning and Zierler System – 1953
• Implemented on the MIT Whirlwind computer
• First "algebraic" compiler system
• Subscripted variables, function calls, expression translation
• Never ported to any other machine
10. The 1950s: The First Programming
Language
• Pseudocodes: interpreters for assembly language like
• Fortran: the first higher level programming language
• COBOL: he first business oriented language
• Algol: one of the most influential programming languages ever
designed
• LISP: the first language to depart from the procedural paradigm
• APL: A Programming Language
11. The 1960s: An Explosion in Programming
Languages
• The development of hundreds of programming languages
• PL/I designed in 1963-4
– supposed to be all purpose
– combined features of FORTRAN, COBOL and Algol 60 and more!
– translators were slow, huge and unreliable
– some say it was ahead of its time......
• Algol 68
• SNOBOL
• Simula
• BASIC
12. The 1970s: Simplicity, Abstraction, Study
• Algol-W - Nicklaus Wirth and C.A.R.Hoare
– reaction against 1960s
– simplicity
• Pascal
– small, simple, efficient structures
– for teaching program
• C - 1972 - Dennis Ritchie
– aims for simplicity by reducing restrictions of the type system
– allows access to underlying system
– interface with O/S - UNIX
13. The 1980s: Consolidation and New
Paradigms
• Ada
– US Department of Defence
– European team lead by Jean Ichbiah. (Sam Lomonaco was also on the ADA team :-)
• Functional programming
– Scheme, ML, Haskell
• Logic programming
– Prolog
• Object-oriented programming
– Smalltalk, C++, Eiffel
14. Functional Programming
• Common Lisp: consolidation of LISP dialects spurred practical use,
as did the development of Lisp Machines.
• Scheme: a simple and pure LISP like language used for teaching
programming.
• Logo: Used for teaching young children how to program.
• ML: (Meta Language) a strongly-typed functional language first
developed by Robin Milner in the 70’s
• Haskell: poly morphicly typed, lazy, purely functional language.
15. Small talk (1972-80)
•Developed at Xerox PARC by Alan Kay and colleagues (esp. Adele
Goldberg) inspired by Simula 67
•First compilation in 1972 was written on a bet to come up with "the
most powerful language in the world" in "a single page of code".
•In 1980, Smalltalk 80, a uniformly object-oriented programming
environment became available as the first commercial release of the
Smalltalk language
•Pioneered the graphical user interface everyone now uses
•Industrial use continues to the present day
16. C++ (1985)
•Developed at Bell Labs by Stroustrup
•Evolved from C and SIMULA 67
•Facilities for object-oriented programming, taken partially from SIMULA
67, added to C
•Also has exception handling
•A large and complex language, in part because it supports both procedural
and OO programming
•Rapidly grew in popularity, along with OOP
•ANSI standard approved in November, 1997
17. Eiffel
Eiffel - a related language that supports OOP
- (Designed by Bertrand Meyer - 1992)
- Not directly derived from any other language
- Smaller and simpler than C++, but still has most of the power
18. 1990’s: the Internet and Web
During the 90’s, Object-oriented languages (mostly C++)
became widely used in practical applications
The Internet and Web drove several phenomena:
– Adding concurrency and threads to existing languages
– Increased use of scripting languages such as Perl and Tcl/Tk
– Java as a new programming language
19. Java
• Developed at Sun in the early 1990s
with original goal of a language for
embedded computers
• Principals: Bill Joy, James Gosling, Mike
Sheradin, Patrick Naughton
• Original name, Oak, changed for copyright reasons
• Based on C++ but significantly simplified
• Supports only OOP
• Has references, but not pointers
• Includes support for applets and a form of concurrency (i.e. threads)
20. The future
• In the 60’s, the dream was a single all-purpose language
(e.g., PL/I, Algol)
• The 70s and 80s dream expressed by Winograd (1979)
“Just as high-level languages allow the programmer to escape the intricacies of
the machine, higher level programming systems can provide for manipulating
complex systems. We need to shift away from algorithms and towards the
description of the properties of the packages that we build. Programming
systems will be declarative not imperative”
• Will that dream be realised?
• Programming is not yet obsolete

37. Comparing the performance of Mojo,
Python, and JavaScript
Comparing the performance of Mojo, Python, and JavaScript in the context of
machine learning.
According to a Medium article, Python and Mojo are two popular programming
languages that have been widely used in various applications, from web
development to machine learning. While both Python and Mojo share some
similarities, they also have notable differences that set them apart. As a developer or
programmer, it’s essential to understand the fundamental differences between these
languages so that you can choose the one that best suits your needs.
Another Medium article compares the performance of JavaScript and Python for
machine learning. The article states that JavaScript’s computational performance is
still much better than Python’s. However, the maturity of the libraries — which
often have underlying modules written in C — means that operations on large
datasets can offer so much more than sheer computational power. But there is still a
place for JavaScript in machine learning.
38. Programming Languages for Civil
Engineering
• Civil and Structural engineering are fields that require a lot of computational power. Learning to code can
help engineers automate repetitive tasks, improve their workflow, and increase their productivity. According
to The Computational Engineer, the following programming languages are commonly used in the civil and
structural engineering industry 1:
1. Grasshopper: A visual programming language that can be easily adopted by civil and structural engineers. It
is a plugin to a CAD and 3D-modelling software called Rhinoceros. It has a low bar to entry but is powerful
enough to manage most of your workflows, including your Revit workflows.
2. Dynamo: A popular visual programming language for building and civil engineers. It is a plugin for Autodesk
Revit and can be used to automate repetitive tasks and improve workflows.
3. BHoM: A data structure and toolset for building and architecture that can be used to create custom
workflows and automate tasks.
4. C#: A general-purpose programming language that is widely used in the civil engineering industry. It is used
to develop software applications and tools for civil engineering projects.
• These languages have been designed with civil engineering workflows in mind and offer a lower bar to entry
for civil and structural engineers. They are also powerful enough to manage most of your workflows,
including your Revit workflows. If you are new to coding, Grasshopper is a great first language to learn as it
has an easy-to-adopt and debug interface 1.
