...ipt. The easy way: The readAsDataURL() method might already encode it as base64 for you. You'll probably need to strip out the beginning stuff (up to the first ,), but that's no biggie. This would take all the fun out though. The hard way: If you want to try it the hard way (or it doesn't work),...

The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: 6 Ans...

...e method crypto.randomBytes that generates a random Buffer. However, the base64 encoding in node is not url-safe, it includes / and + instead of - and _ . Therefore, the easiest way to generate such token I've found is ...

... most reliable way to check for this is to check whether sys.prefix == sys.base_prefix. If they are equal, you are not in a virtual environment; if they are unequal, you are. Inside a virtual environment, sys.prefix points to the virtual environment, and sys.base_prefix is the prefix of the system P...

...ould like to stress how much the representation of a number depends on the base you are working in. Consider the fraction 2/3 In good-ol' base 10, we typically write it out as something like 0.666... 0.666 0.667 When we look at those representations, we tend to associate each of them with the ...

If you look back at Smalltalk, since you can open ...

.....), an instance of type (i.e. a class) is created by myclass = type(name, bases, clsdict). If you want something special to happen at the moment of class-creation, then you have to modify the thing creating the class -- i.e. type. The way to do that is to define a subclass of type -- i.e. a metacl...
