How many lines of code did Margaret Hamilton?

There are 17 binders in the photo. Assuming the pile is 5″4′, they're all code (not simulation), and applying Mike's measurements assuming 10 binders are Aurora-like and 7 are Luminary-like yields 14,500 code pages, about 660,000 code lines.

How many lines of code did Apollo 11 use?

As an aside: Apollo 11 had 145,000 lines of code. Google has about 2 billion lines of code. Part of what makes that possible is that Google's code is mostly written in languages like Python, not in AGC assembly language.

What did Margaret Hamilton code?

On July 20 of 1969, just as the Apollo 11 astronauts were about to land on the moon, something unexpected happened that stopped the heartbeats of the entire crew at Mission Control in Houston.

What programming language did Margaret Hamilton use?

Hamilton talks about "Errors" and how they influenced her work related to software engineering and how her language, USL, could be used to prevent the majority of "Errors" in a system.

Who wrote the code for Apollo 11?

Hamilton hand-wrote the code for the Apollo missions, and when a last-minute problem cropped up as Apollo 11 prepared for a lunar landing, it was Hamilton's forward-thinking code that saved the day!

Command Lines: Margaret Hamilton

Did Margaret Hamilton wrote the code by hand?

In very, very small chunks. Margaret and her team at MIT programmed the Apollo Guidance Computer in an Assembly Language unique to that computer. They wrote their code on special coding forms, then gave it to keypunch operators who keyed it into a computer so that it could be printed out and checked over.

How many lines of code got us to the Moon?

There are 40.202 lines of code. There are no files without comments, 31.443 of the lines contain a comment and there are 5900 blank lines used. The software was submitted by 1 person and approved by 6 other people. Temporary does not exist in programming.

What programming language is Apollo 11?

The Apollo Guidance Computer (AGC) was installed on board the Apollo 11 Command Module (CM) and Lunar Module (LM). The computer's software was written in Assembly Language (or Assembler).

Who is the world best software engineer?

What programming language did NASA use?

HAL/S is a high-level programming language commissioned by NASA in the late 1960s to meet the real-time programming needs of the Agency. At the time, programs used on board spacecraft were either written in assembly languages or in interpreted languages.

Who coded the Apollo mission?

Today, Margaret Hamilton is retired. At 85 years old, she is considered one of the biggest pioneers of computer science, and one of the driving forces that helped make the Apollo mission a success.

Who programmed the first moon landing?

On the Apollo 11 mission, Margaret Hamilton watched as the software designed by her team guided astronauts Neil Armstrong and Buzz Aldrin toward the Moon's surface.

What caused the 1201 alarm on Apollo 11?

Eventually the Executive found that there was no place to put new programs. This triggered the 1201 alarm signaling “Executive Overflow — No Core Sets” and the 1202 alarm signaling “Executive Overflow — No VAC Areas.” These in turn triggered a software reboot.

How many lines of code does a space shuttle have?

The Space Shuttle, apparently, has only some 400,000 lines of code. This is a vehicle that goes into space.

How much memory did the Apollo computer have?

This means that the Apollo computer had 32,768 bits of RAM memory. In addition, it had 72KB of Read Only Memory (ROM), which is equivalent to 589,824 bits.

What program is used to explore the moon?

The Apollo program, also known as Project Apollo, was the third United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first humans on the Moon from 1968 to 1972.

Who is No 1 coder?

Gennady Korotkevich (Belarusian: Генадзь Караткевіч, Hienadź Karatkievič, Russian: Геннадий Короткевич; born 25 September 1994) is a Belarusian competitive programmer who has won major international competitions since the age of 11, as well as numerous national competitions.

Does Mark Zuckerberg know coding?

Mark Zuckerberg learned to code not long after he received his first computer as a sixth grader. Zuckerberg was instantly interested in coding, eventually turning to C++ for Dummies to teach himself programming. In 2013, Zuckerberg explained his motivation.

Which country is best in coding?

According to our data, China and Russia score as the most talented developers. Chinese developers outscore all other countries in mathematics, functional programming, and data structures challenges, while Russians dominate in algorithms, the most popular and most competitive arena.

How much RAM did it take to get to the Moon?

The Apollo Guidance Computer had RAM of 4KB, a 32KB hard disk. It was fairly compact for its time, measuring 60cm x 30cm x 15cm, but weighed around 30kg. Current computers are much lighter, at least 1000 times as fast and have storage capacities that are millions of times those achievable in 1969.

How much RAM did the first space shuttle have?

Fact: your smart phone has more computing power than the original space shuttle, which used only 1MB of RAM.

What is Fortran code?

Fortran (/ˈfɔːrtræn/; formerly FORTRAN) is a general-purpose, compiled imperative programming language that is especially suited to numeric computation and scientific computing.

Which programming language came first?

Computer Programming History: FORTRAN was the first computer programming language that was widely used.

How was the Apollo guidance computer programmed?

Apollo's computer used erasable merry cells to store intermediate results of calculations, data such as the location of the spacecraft, or as registers for logic operations. In Apollo, they also contained the data and routines needed to ready the computer for use when it was first turned on.

How does core rope memory work?

In rope memory, bits of information are represented by threads of wire and tiny doughnut-shaped magnetic cores. A core with wire threaded through the center represents a 1; an empty core represents a 0. In this way, the pattern of wires can form a computer program—software crystallized as hardware, in other words.
