by Dannar26 in Java

Here is my source code. I got the reading part but need a simple logic for my writing part which I"m not getting. Here in my current logic, data gets overwritten and I'm always able to see the last block of read data in my written file.

import java.io.FileInputStream;

I seem to be retaining self inside a block even when using an indirect __block reference to it, perhaps cause of copying the block to the heap?
by dougbeal in Development Tools & Services

[EDIT: Since it was causing confusion, this whole case assumes MRR and not ARC]


I'm having an odd (there's an explanation obviously, I just can't figure it out) behavior with a block which references self (indirectly) and is in turned copied to another object's property (that is, copied from object As' stack to the heap and retained by an object B). If the block doesn't contain the


Does an exception in one statement in a try block cause control flow to bypass any remaining statements in the try block?
by smbrant in Programming Languages

GradedCourse c(cVal, gr); // If an exception is thrown here...

} catch(...) {
throw;

Read, Slice and Re-structure data file block-by-block in Python
by kalfa in Coding

A text file generated by a fortran program contains "blocks" data, that need to be reformatted (Python script).


Each "block" of data in this file corresponds to the "Time:" specified in the beginning of the block. All "blocks" have a fixed size and structure.


I need to extract the data from "Head" and "Moisture" columns corresponding to different "Depths" (0, -1, and -
