A friend approached me asking how he could go about changing the flow of execution of his program during runtime using a debugger. This sounded interesting because I knew in theory what to do, but had not applied this knowledge since the early to mid 2000s, when problems like these were my playground as a C programmer yearning to learn about system internals. After I gave him a rundown and demo, he asked, What if the binary is stripped? Well, that is slightly different and it is far more complex to put together, but let's give it a go.

| A fellow had just been hired as the new CEO of a large high tech | |
| corporation. The CEO who was stepping down met with him privately and | |
| presented him with three numbered envelopes. "Open these if you run up | |
| against a problem you don't think you can solve," he said. | |
| Well, things went along pretty smoothly, but six months later, sales | |
| took a downturn and he was really catching a lot of heat. About at his | |
| wit's end, he remembered the envelopes. He went to his drawer and took | |
| out the first envelope. The message read, "Blame your predecessor." |
