What is the maximum amount of RAM an app can use?
...significant determinant, as larger resolutions mean larger bitmaps, and so tablets and high-resolution phones will tend to have higher values yet. For example, you will see devices with 48MB heaps, and I wouldn't be surprised if there are values higher than that.
How is it possible that apps exc...
What is the difference between a process and a thread?
...s needed to execute a program. A process has a virtual address space, executable code, open handles to system objects, a security context, a unique process identifier, environment variables, a priority class, minimum and maximum working set sizes, and at least one thread of execution. Each process i...
When and why will a compiler initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete?
... Or that memory just has been freed by HeapFree().
Disclaimer: the table is from some notes I have lying around - they may not be 100% correct (or coherent).
Many of these values are defined in vc/crt/src/dbgheap.c:
/*
* The following values are non-zero, constant, odd, large, and atypica...
Is there any way to put malicious code into a regular expression?
... spent begging the operating system for more space, and the attendant page-table set-up costs, can sometimes nudge the balancing scale further the other way and make the conversion from time to space less attractive than it would be.

I then upload this template to AWS, walk away, and 45 minutes later everything is ready and waiting. Since it's just a plain-text JSON file, I can stick it in my source control whi...

Microsoft Roslyn vs. CodeDom
...e, we've exposed public APIs on top:

Chaining multiple filter() in Django, is this a bug?

Is it safe to parse a /proc/ file?

To see this, look at listening_get_next() in net/ipv4/tcp_ipv4.c and established_get_next() just below in the same file, and see the locks they take out on each entry in turn.
