How do I detect unsigned integer multiply overflow?
...
};
return bits;
}
It's not perfect, but that'll give you a good idea whether any two numbers could overflow before you do the operation. I don't know whether it would be faster than simply checking the result the way you suggested, because of the loop in the highestOneBitPosition function...
Error handling principles for Node.js + Express.js applications?
...an application which will try very hard to never crash. This is a terrible idea in nearly every use-case, because it will leave the developer without any idea of what's going on in the application state and is analogous to wrapping main in try-catch.

The idea behind this message is for the sake of readability. We expect to find all the attributes an instance may have by reading its __init__ method.

Are there legitimate uses for JavaScript's “with” statement?
...truct. It's a lot like encountering fall through on a switch, you have no idea if the author intended this and there's no way to know if "fixing" the code will introduce a regression.

What is the best practice for “Copy Local” and with project references?
... people suggesting sharing an output directory; I think this is a horrible idea based on experience. If your startup project holds references to a dll that any other project holds a reference to you will at some point experience an access\sharing violation even if copy local = false on everything a...
Appending an element to the end of a list in Scala
...ul pattern if you have many elements to add, but I don't think it's a good idea to apply it like you do in the case of adding a single element to an existing list. The "double reverse" trick rebuilds the list twice, while :+, inefficient as it may be, only rebuilds it once.
