MyISAM versus InnoDB [closed]
...nserts and 30% reads ). This ratio would also include updates which I consider to be one read and one write. The reads can be dirty (e.g. I don't need 100% accurate information at the time of read).
The task in question will be doing over 1 million database transactions an hour.

Need to reset git branch to origin version
I was accidentally working on a branch I shouldn't have been for a while, so I branched off of it giving it the appropriate name. Now I want to overwrite the branch I shouldn't have been on to the version from origin (github). Is there an easy way to do this? I tried deleting the branch and then ...
Boost Statechart vs. Meta State Machine
... Minor nit-pick: In release mode, the use of C++ RTTI (dynamic_cast, typeid) is strictly optional with Boost.Statechart.

Is module __file__ attribute absolute or relative?
...so that the initial
value of sys.path is ''.
For the rest of this, consider sys.path not to include ''.

Notice how they're both green now; the code didn't run until HTML parsing was complete. That would also be true with a defer script with external content (but not inline content).

How to check if a variable is a dictionary in Python?
...em from inheriting a bad implementation to begin with ('god object's, overriding standard library/language constructs, etc.) The original question is itself an XY problem. Why does the OP need to check type? Because according to their code what they really want to do is to check whether an item in t...
What is the explicit promise construction antipattern and how do I avoid it?
... asynchronous code more readable and behave like synchronous code without hiding that fact. Promises represent an abstraction over a value of one time operation, they abstract the notion of a statement or expression in a programming language.

What is the advantage of using forwarding references in range-based for loops?
...you need to operate on that reference in a non-const way. For example consider:
#include <vector>
int main()
{
std::vector<bool> v(10);
for (auto& e : v)
e = true;
}
This doesn't compile because rvalue vector<bool>::reference returned from the iterator won'...
