...iterator returns constant pointers” which is not accurate, thanks to Brandon for pointing it out. Edit: For COW objects, getting a non-const iterator (or dereferencing it) will probably trigger the copy. (Some obsolete and now disallowed implementations of std::string use COW.) ...

If Python does not have a ternary conditional operator, is it possible to simulate one using other language constructs? 26 ...

...lement pools of reusable objects - instead of building, using, and tearing down an object, if the construction and destruction are expensive processes it might make more sense to build them once and recycle them. The factory method can return an existing, unused instantiated object if it has one, o...

... No need to stash. git checkout -b new_branch_name does not touch your local changes. It just creates the branch from the current HEAD and sets the HEAD there. So I guess that's what you want. --- Edit to explain the result of checkout master --- Are you confused because ch...

...avaScript framework designed to allow developers to literally "write less, do more", the 3 different flavours you are asking about, do very different things. First up jQuery is the core library which contains the main functionality of the framework, so if you want to make an element fade in, you w...

... Code changes are minimal to add this support. It would be MUCH harder to do this data access code that simply calls sprocs. Debugging support: I can use any .NET debugger to debug the queries. With sprocs, you cannot easily debug the SQL and that experience is largely tied to your database vendor...

...ifying the type (<input type="number">) you're asking the browser to do some work for you. If, on the other hand, you'd like to be able to capture the non-numeric input and do something with it, you'd have to rely on the old tried and true text input field and parse the content yourself. The...

I've taken some shared code and put it in an NPM module, one I don't want to upload to the central registry. The question is, how do I install it from other projects? ...

... This is not something that SVG 1.1 supports. SVG 1.2 does have the textArea element, with automatic word wrapping, but it's not implemented in all browsers. SVG 2 does not plan on implementing textArea, but it does have auto-wrapped text. However, given that you already know w...

...rmance is probably important. So it's probably safe to guess that this was done for performance reasons. Multiplying by the reciprocal is faster than repeatedly dividing by 255. Side Note: If you're wondering why such a micro-optimization isn't left to the compiler, it's because it is an unsafe...
