I'm a beginning C programmer. As an exercise, I have attempted to implement a stack of strings in C. This is my first real excercise working with pointers. I looked at some other similar posts on here, and read through the comments. It seems that most individuals have chosen to do this by using l...
In A Tour of Go, you are given the following problem:
In this exercise you'll use Go's concurrency features to parallelize a
web crawler.
Modify the Crawl function to fetch URLs in parallel without fetching
the same URL twice.
This is the code you're given

When we are adding a new function to existing file where will it place.
Place at bottom/top - so that we can easily identify newly added function
Place with related functions - so that it is easy to find a its caller function.
I have a package directory pkg with several classes that I would like to build into a convenient dict property.
The structure of pkg/ looks like:

class _MyBase(object):
pass
pkg/foo.py:
from .base import _MyBase
class Foo(_MyBase):
pass
And in pkg/__init__.py, it is...

I'm writing this as (eventually) part of a larger program. This will serve as the bulk data insertion from csv files we parse.
I'm primarily looking for parts that are (1) breaking Go's formatting, styling, etc. rules, and (2) redundant and/or dangerous.
Right now the code works and all 4 milli...

My IDE (PHP Storm from jetbeans) keeps complaining about "duplicated jquery selectors", as you can see in the image below.
Is this something I could code differently, or is my IDE just off?

self.x, self.y = x, y
print "New Point object", self, "constructed"

I've written a function that wraps the classList API, allowing you to pass an array of classes to add/remove, or the variable arguments already supported by classList. The methods are the following:

};

I was given some JUnit test to review.
The class under test uses four hibernate daos, one delegating EJB and one ThreadLocal variable.
The programmer who wrote the unit test made a point to mock every single object he finds. This includes objects (POJOs) returned by the DAOs or the delegating E...
This simulated annealing program try to look for the status that minimize the energy value calculated by energy function.

I'm having trouble finding results for the internal workings of WiFi Protected Setup.

I was reading a comic from XKCD which inspired me to ask this question: "well, where do they go when it rains?" I know that when it rains you usually don't see any birds flying through the sky.
I imagine they normally hide in trees or under other kinds of cover. But for migratory birds, I don't ...

In our application, we have many function calls that we want to cache the results of. However, the result of these functions depends on database calls, so we want this cache to refresh every so often so that new data is pulled from the database on a regular basis.

I flagged this SO question for migration to Code Review.

The question was as...
