The value of backwards compatibility is directly proportional to the ratio of "value of user time" / "value of dev time". Depending on whether you are the dev, the user or a third party, you may attach different val

Maybe I'm missing something, but it doesn't sound like it's _that_ specific. From the instructions, the conditions for the bug are: 1. Running Android 10 or higher 2. Has MS Teams installed 3. User is logged out of MS Teams 4

I don't find that to be a convincing argument, because it suggests we should write "foo applied to bar" instead of "foo(bar)" in your code. It's just notation, just because it's new, doesn't mean it&#

Part of the reason for that is because APL-family languages support this feature as a first class citizen and are designed with them in mind. Numpy has to, for better or worse, work within the confines of the Python grammar.

Neat trick. Didn't know about it. In pandas it would be item.foo = bar, _as long as_ bar isn't something you can iterate over.

Indeed, doing the infinite sum is the "hard" way. The easier way is to notice that the trains will collide in 1h and the fly will be constantly be flying at a speed of 60mph for the entire time. So the fly will travel 60 miles in

A nuance here is that you are assuming the existence of a solution. It may be the case there are no values for A to J that can result in that equation. Iterating through all possibilities shows that the solution exists, the proof in the twe

Presumably, it's not just landlords that are shouldering the risk. Also, the US budget is huge and has a lot of buffer room. Worst case you're trading off investing in future development projects with keeping the market stable.
