Git branching strategy integated with testing/QA process
...ture branch is (automatically) deployed on our TEST environment with every commit for the developer to test.
When the developer is done with deployment and the feature is ready to be tested he merges the develop branch on the feature branch and deploys the feature branch that contains all the lates...
What is the curiously recurring template pattern (CRTP)?
... Apple a2;
a1.size = 10;
a2.size = 10;
if(a1 == a2) //the compiler won't complain!
{
}
}
This could seem that you would write less if you just wrote operator == for Apple, but imagine that the Equality template would provide not only == but >, >=, <= etc. And you...
How can I reliably get an object's address when operator& is overloaded?
...d of boost::addressof.
Let us first copy the code from Boost, minus the compiler work around bits:
template<class T>
struct addr_impl_ref
{
T & v_;
inline addr_impl_ref( T & v ): v_( v ) {}
inline operator T& () const { return v_; }
private:
addr_impl_ref & operat...
Why is there a difference in checking null against a value in VB.NET and C#?
...de different assumptions about usage; in this case the semantics of a NULL comparison.
My personal preference is for the VB.NET semantics, which in essence gives NULL the semantics "I don't know yet". Then the comparison of 5 to "I don't know yet". is naturally "I don't know yet"; ie NULL. This has...
techniques for obscuring sensitive strings in C++
...OR key2
If you create key1 with the same byte-length as key you can use (completely) random byte values and then compute key2:
key1[n] = crypto_grade_random_number(0..255)
key2[n] = key[n] XOR key1[n]
You can do this in your build environment, and then only store key1and key2 in your applicatio...
How to extract the decision rules from scikit-learn decision-tree?

I agree with the previous comment. IIUC, print "{}return {}".format(indent, tree_.value[node]) should be changed to print "{}return {}".format(indent, np.argmax(tree_.value[node][0])) for the function to return the class index.

Depending upon what Microsoft browsers you support you may not need to continue using the X-UA-Compatible tag. If you ne...
