python 3.x ImportError: No module named ‘cStringIO’
From Python 3.0 changelog: The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively. From the Python 3 email documentation it can be seen that io.StringIO should be used instead:
Can we use & in url?
Yes, you can use it plain in your URL path like this: Only if you want to use it in the query you need to encode it with %26: Otherwise it would be interpreted as argument separator when interpreted as application/x-www-form-urlencoded. See RFC 3986 for more details.

Arithmetic Overflow in mips
According to the MIPS instruction reference, the only addition operations which can produce overflow exceptions are the signed addition instructions: MIPS integers are 32-bit, and since you’ll be using signed integers, the maximum value is 231-1 (aka 2147483647 or hex 7FFFFFFF). Thus any addition which results in a number larger than this should throw an exception, … Read more
What’s the use of the staging area in Git?
There are many uses of staging in Git. Some are listed below: staging helps you split up one large change into multiple commits – Let’s say you worked on a large-ish change, involving a lot of files and quite a few different subtasks. You didn’t actually commit any of these — you were “in the zone”, … Read more
Multiplying a register value by a constant in MIPS?
MIPS instruction set doesn’t provide a mult instruction with immediate value. Hence you would have to store the value into a temporary register and then use mult instructions. The result of the mult instruction would be stored in lo and hi registers giving the lower 32-bit of the result and upper 32-bit of the result … Read more
C’s printf and fprintf(stdout,) are not printing
Output is often buffered by the system. You can call fflush, but sometimes, depending on how the caching works, simply ending the output with a newline is sufficient. So try changing to And, if that doesn’t help, to (And stderr often isn’t cached, as you want to see errors immediately.) Finally, you will see output … Read more
