uiuc | A JS wrapper for U of I 's Course Schedule/Catalog API | REST library

Following @lrnv suggestion about multi_future, the following code should correctly display the progress of a pool of workers.

but apparently all of these are allowed. Can someone please explain how the others work?

Alex, you need to check the variables properly. You have declared classifier as variable for DecisionTreeClassifier but you are using dtc in the end. Replace dtc with classifier:

You didn't declare the constructor in your .h file.

It should look like this:

As far as I'm aware there is no equivalent to filter-out in nmake. Also, nmake does not support the wildcard function so you'll have to deal with that. And, I'm suspicious that your replacement for += won't work; in most versions of POSIX make FOO = $(FOO) is illegal as it gives an infinite loop of variable lookup. Maybe nmake works differently, though.

nmake is SO different from POSIX make and GNU make that you will either have to rewrite the makefile from scratch, or else just go get a version of GNU make for Windows (or build it yourself). GNU make is quite portable and runs well on Windows. That would be a LOT less work.

The issue is that you are missing a parenthesis in the computation of M :

Functions first declared as friend in a class are placed in the enclosing namespace, so the function you want to define must be defined in the uiuc namespace.

You might be under assumption that if you use using namespace uiuc; new declarations/definitions will be placed into the uiuc namespace, but that is not the case. using namespace only affects the lookup of names, not where declarations/definitions are placed.

Therefore the function you are defining at the moment is operator<<(std::ostream & os, uiuc::Game & game) in the global namespace scope (which is not a friend of uiuc::Game), not operator<<(std::ostream & os, Game & game) in the uiuc namespace.

So you need to open the namespace properly:

Maybe like this:

You've mostly answered your own question but to cover your issue, the pymongo drivers will always add an _id field to the data on insertion.

When a document is inserted a special key, "_id", is automatically added if the document doesn’t already contain an "_id" key. Reference

See this simple example. If you don't want the _id field, just pop it after the insert; alternatively you can take a copy of the data into a new variable before inserting it.
