Kaizen and Kaikaku

An airhacks.fm conversation with Daniel Terhorst-North (@tastapod.com) about:

first computer experience with the ZX81 and its 1K memory, the 1K chess game on ZX81, the ZX Spectrum with 16K and later 48K memory, the Amstrad 128K, typing in game listings from computer magazines, Dan's brother John hacking ZX spectrum games using a hardware freeze device and memory peeking/poking, cracking game encryption and copy protection on 8-bit tape cassette games, the arms race between game publishers and hackers, cracking the Star Wars game security before its release, ZX Spectrum fan sites and retro gaming communities, classic games including 3D Monster Maze and Manic Miner and Jet Set Willy, sprite graphics innovation on the Z80 chip, first internship at Domark publishing Empire Strikes Back on ZX Spectrum and Commodore 64, second internship at IBM Hursley Park working on CICS in PL/1 and Rexx, the contrast between casual game studio culture and IBM corporate culture in the 1980s, IBM's role as a founding partner of J2EE Enterprise Java, JMS wrapping MQ Series, the reliability of MQ Series compared to later messaging technologies, finding and reporting a concurrency bug in MQ Series with JUnit tests and IBM's rapid response with an emergency patch, IBM alphaWorks portal and experimental technologies, IBM Aglets mobile Java agent framework compared to modern A2A agent protocols, Jini and JavaSpaces from Sun Microsystems with leasing and self-healing, JXTA peer-to-peer technology, IBM Jikes Compiler performance compared to javac, IBM's own JVM, JVM running on Palm Pilot around 1999, VisualAge for Java as a port of VisualAge for SmallTalk with its image-based architecture and no file system exposure, Java's coupling of class and package names to files and directories as a design weakness, the difficulty of refactoring without IDE support, Eclipse as the first IDE with proper refactoring, NetBeans IDE performance compared to Visual Studio Code, third internship writing X-ray machine control software in Turbo Pascal doing digital image processing, the pace of technological innovation slowing from kaikaku (abrupt change) to kaizen (continuous improvement), Douglas Adams quote about technology perception by age, DEC Alpha 64-bit Unix performance, commodity Linux hardware replacing exotic RISC machines, Apple M series chips rediscovering RISC Architecture and system-on-chip design, innovation fatigue and signal-to-noise ratio in modern tech, LLMs and the trillion-dollar bet on the wrong technology, electric cars as an example of ongoing innovation, Tailwind CSS shutting down due to AI-generated code replacing paid expertise, Stack Overflow in trouble due to AI summarization, open source innovation continuing with tools like Astral's uv replacing the python toolchain, cross-community collaboration between rust and Python and Ruby ecosystems, first graduate job at Crossfield (Fuji/DuPont joint venture) doing electronic pre-press and color transformation through 4D CMYK color cubes, writing a TIFF decoder from scratch in C, Raster Image Processor technology and its connection to Adobe, transition from C++ to Java feeling quirky, joining ThoughtWorks in 2002 for enterprise Java work
