an evaluator that is written in the same language that it evaluates is said to be metacircular[1]. Note that this is not the case here because it's not a python interpreter but a cpython bytecode interpreter. It would have been metacir

I once wrote a tool like that but for gnu+linux. You first have to retrieve the memory mapping of the targeted process by reading /proc/<PID>/maps [1] then use process_vm_read/write[2] [1] http://man7.or

The first part of the paper compares token threading vs naive switch in cpython 3.2 which has a compile flag to disable token threading[1]. I were referring to direct threading but the difference is probably minor or irrelevant. on x64, tok

The coupling of a cryptoprocessor[1] to avoid network packets and circuitry tampering with a locked kernel could stop people to use cheats. The CPU would only execute a signed kernel[2] while the kernel would only load signed modules. Today

Pharo is great for doing Test driven development: 1. write a test 2. run the test 3. test fails; debugger pop up 4. implement/fix the method inside the debugger 5. repeat at 2 until the test succeed. it's usual that a coding sessi

we want to establish the idea that a computer language is not just a way of getting a computer to perform operations but rather that it is a novel formal medium for expressing ideas about methodology. Thus, programs must be written for peo
