This is the number one error. You tried to access a file that doesn’t exist. Because the Unix file I/O system doesn’t discriminate between files and directories, this error message occurs everywhere. You get it when you try to read a file that does not exist, when you try to change...
⟹ Key observation:We can play with the 16-byte bin that is used to serviceRequestobjects from the heap. If we could somehow get a dangling pointer to a Request object, we could corrupt that Request and then carefully use the corrupted object's overwrittenchar *strpointer to perform arbitr...

Add a comment 0 Unfortunately the simple solution x/numpy.linalg.norm(x) doesn't work if x is an array of vectors. But with a simple reshape() you can force it into a flat list, use a list comprehension, and use reshape() again to get back the original shape. s=x.shape np....
Since you cannot1mutate the value returned fromget, I'd just return a reference to the default value when the value is missing. When you callget_muthowever, you can then add the value to the map and return the reference to the newly-added value. ...
I am running Lumerical FDTD on a cluster, but it always after a bit of simulation calls "terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc APPLICATION TERMINATED WITH THE EXIT STRING: Hangup (signal 1)" This appears like a memory issue, but I ha...
On x86-64, up to six arguments come in as registers; after that they get pushed onto the stack. If you're returning a value, it goes into %rax. The return address is automatically pushed onto the stack by call instructions like e8 <32-bit relative>. So internally, call is the same...
