Welcome to the forty-third issue of De Programmatica Ipsum, dedicated to the subject of Types. In this edition:
- Graham crafts a Motorola 6809 CPU emulator to show that types are useful, but not needed.
- Adrian reviews history and literature to show that types are useful, but should not be abused.
- In the Library section, Graham reviews “Recoding Gender” by Janet Abbate.
This magazine denounces and abhors Russia’s invasion of Ukraine. We urge Russia to withdraw its troops, and NATO to stop its expansion immediately. There must be an immediate reduction of nuclear weaponry worldwide, and we call on all sides to de-escalate and seek peaceful solutions. We express our deepest solidarity to all those campaigning for an end to the war, often under very difficult conditions, in Russia and Ukraine.
