Questions & Answers

Q: What was the first program Jeremy Howard wrote?

The first program he remembers writing was on his Commodore 64 in high school. It was a program to search for musical scales that were more accurate than the normal twelve-tone twelve-interval scale.

Q: Where did the interest in music come from?

Howard had been involved in music throughout his life. He played several instruments, including the saxophone, and had a love for music coupled with programming.

Q: What are some programming languages Howard has used?

Some of the programming languages Howard has used include Microsoft Access, Visual Basic for Applications, Perl, and Python. He discusses the pros and cons of each and highlights the power and ease of use of Microsoft Access.

Q: What was the connection between Excel and Access?

Access was the relational database equivalent to Excel. While Excel is great, Access provided a more robust programming model with the ability to create user interfaces, tie data to actions, and create reports.

Q: What are the limitations of programming on top of a relational database?

Programming on top of a relational database can be cumbersome, requiring additional layers such as ORMs (Object-Relational Mappers). There is a need for a more streamlined programming model, which projects like F# aim to achieve.

Q: What is J, and how does it compare to other programming languages?

J is an array-oriented programming language that is highly expressive and composable. It is a powerful language with a compact notation, allowing you to do a lot with just one line of code.

Q: How does J compare to more modern programming languages like Swift or Pascal?

J is a unique language that doesn't have a direct modern equivalent. However, Swift with its focus on hackability and functional programming could potentially achieve a similar level of expressiveness in the future.

Q: Why is most research in deep learning a waste of time?

Howard believes that most research in deep learning is focused on minor advances and highly studied areas, which often lack practical impact. He highlights that important areas like transfer learning and active learning are under-studied but have the potential to be world-changing.
