Alfred Tennyson,
5 Aug 1809 -6 Oct 1892
Every moment dies a man,
Every moment dies a man,
Every moment 1 1/16 is born."
Every moment one is born.
3. Sir:
In your otherwise beautiful poem "The Vision of Sin" there is a
verse which reads – "Every moment dies a man, Every moment
one is born." It must be manifest that if this were true, the
population of the world would be at a standstill. In truth, the rate of
birth is slightly in excess of that of death.
I would suggest that in the next edition of your poem you have it
read – "Every moment dies a man, Every moment 1 1/16 is born."
The actual figure is so long I cannot get it onto a line, but I believe
the figure 1 1/16 will be sufficiently accurate for poetry.
I am, Sir, yours, etc.,
Charles Babbage

10. Programming Language Generations
• First Generation
Machine-level programming
languages
– Fast and efficient, executed
directly on the CPU
– Consists only of 0s and 1s
– Difficult for humans to read, write,
and debug
11. Programming Language Generations
• Second Generation
(early 1950s):
– Symbolic assemblers
– Interpreting routines
– Very early compilers
Assembly languages
– Simple mnemonic instructions <opcode> <operands>
– Assembler translates into machine code
– Handcoding in assembly only for low-level needs
