The question in question (no pun intended): Cutting stock recursion OP basically dumped the problem definition and a solution on us. There is no indication to if the code actually works, it is homework and there is no indication to what the poster want's help with. This is something I've strugg...

The following code is the revised/feedback version of my previous post. The big change was converting RicCache CLASS object to an INSTANTIATED object. I'm attempting to master LRU Caching. It must be thread safe, and it should preferably perform as well as web image-cache, (avg ~1MB). Please t...

I'll start with giving a bit of background as there are many classes involved and I can't attach all of them because that would make this question wildly too long. For the curios they can be found at my github repo. I have an immutable structure called a Chassis which consists of 8 immutable Com...

I was hacking around this morning and wanting to use automatically generate safe-to-use variables from $_POST. Probably not the best use of extract() and compact(), but extract() allowed me to prefix variable names and compact(explode()) seemed like a neat way to stick everything back into an arr...

char *my_fgets(char *Buf, int iMaxCount, FILE *fp) { // Handle basic failures. if(!Buf) return NULL; if(iMaxCount < 1) return NULL; if(!fp) return NULL; // Create a buffer on the heap for our data to be read in char *lbuf = (char*)malloc(iMaxCount); char *p = lbuf; ...
