The Thirty Million Line Problem

108 min, 55 sec
A detailed analysis of the issues with modern hardware and operating systems, and a proposal for a more manageable and efficient approach.
Summary
- Modern hardware and operating systems have become overly complex, leading to inefficiency and unreliability.
- The speaker advocates for a return to a simpler, more direct hardware programming model that would allow for easier operating system creation and better performance.
- This can be achieved by standardizing on a stable hardware interface, or Instruction Set Architecture (ISA), that remains consistent across different hardware iterations.
- Such a standardized ISA would enable more direct programming, reducing the need for large, complex drivers and other software layers.
- The goal is to create an environment where innovation and competition are fostered, resulting in a brighter future for computing.
Chapter 1
Introduction to the topic of modern hardware and operating system complexity.
- The speaker introduces the topic, expressing frustration with the complexity of modern hardware and operating systems.
- The lecture, titled 'The 30 Million Line Problem', aims to address the issues and propose solutions.
- The speaker apologizes for the lack of rehearsal as the lecture was prompted by a pre-stream discussion and acknowledges it may be rough.
Chapter 2
Analysis of the hardware evolution from past to present, highlighting the exponential increase in complexity.
- The speaker contrasts the simple hardware from their childhood with today's complex systems.
- Hardware has seen vast improvements in speed, core counts, memory, and storage, but software has become worse.
- There is a significant increase in the operating system's size, with Linux growing from virtually undetectable to over 18 million lines of code.
Chapter 3
Discussion on the perils of letting hardware and operating system design become unmanageable.
- The complexity of software and operating systems has led to a decline in the user experience.
- Issues like software instability, unwanted updates, and hardware design failures are prevalent.
- The speaker argues that we've fixed the only major problem from the past (lack of memory protection) but have created a slew of new ones.
Chapter 4
Exploring the reasons behind the unreliability and unpleasantness of using software today.
- Software should be more reliable today due to advances in hardware, but it's not.
- The speaker posits that the layering of code upon code has led to a multiplication of failure rates and performance issues.
- A graph of operating system size over time shows a dramatic increase in complexity, which could explain the current state of software.
Chapter 5
A call for a new approach to hardware and operating system design to improve software reliability and usability.
- The speaker suggests we need to look back at how software was more reliable in the past and use that as a starting point for improvement.
- Hardware that was easier to program allowed for many operating systems to be created, which is not the case today.
- To innovate and create better software, we need hardware that is designed to be directly programmable, reducing the need for complex drivers.
