Advanced Level
This is a rating on a scale from 1 to 5 to indicate how advanced the session is (in terms of the specific topic that is being covered) – 1 means that it’s introductory, and 5 means that it’s aimed at attendees who already have significant experience in the relevant area.

Track 2

Frobisher 1 & 2

If considered harmful, or how to eliminate 95% of your bugs in one easy step

Coding Level 2
Advanced Level 4

In 1968, CACM published a letter from Edsgar Dijkstra, called “The GOTO Statement considered harmful”. In it, he explained why most bugs in a program were caused by Gotos, and he appealed for Goto to be expunged from programming languages. But Goto has a twin bother, which is responsible for nearly every bug that appears in programs today. In this session, Jules will revisit Dijkstra’s original explanations, and show why If and Goto have the same pathology. He will then go on to explain how to avoid this pathology altogether.
