• Can python code (say if I used djangno) be obfuscated to the same 'level' as c#/java?

  - by Blankman

  If I obfuscated python code, would it provide the same level of 'security' as c#/java obfuscating? i.e it makes things a little hard, but really you can still reverse engineer if you really wanted to, its just a bit cryptic.

• Do we still need backup code for people who have javascript disabled?

  - by SLC

  I hear about it a bit in tutorials that I watch, that certain things won't work if javascript is disabled. Occasionally I see workarounds. The question is, are these relevent? I can't imagine anyone not having a javascript enabled browser nowadays, except the most ancient of phones, and chances are your page won't render on them properly anyway. Do people still bother to write backup code for javascript being disabled?

• Any pitfalls using char* instead of void* when writing cross platform code?

  - by UberMongoose

  Is there any pitfalls when using char*'s to write cross platform code that does memory access? I'm working on a play memory allocator to better understand how to debug memmory issues. I have come to believe char*'s are preferable because of the ability to do pointer arithmetic and derefernce them over void*'s, is that true? Do the following assumptions always hold true on different common platforms? sizeof(char) == 1 sizeof(char*) == sizeof(void*) sizeof(char*) == sizeof(size_t)

• How can I view the source code for a particular `predict` function?

  - by merlin2011

  Based on the documentation, predict is a polymorphic function in R and a different function is actually called depending on what is passed as the first argument. However, the documentation does not give any information about the names of the functions that predict actually invokes for any particular class. Normally, one could type the name of a function to get its source, but this does not work with predict. If I want to view the source code for the predict function when invoked on objects of the type glmnet, what is the easiest way?
