enum.values() - is an order of returned enums deterministic
...ld for each planet. Then you can have a trivial comparator compare planets based on their mean distance from Sun, and order them using this comparator. This is IMHO a clean and foolproof solution. Whereas your solution breaks as soon as e.g. a new colleague decides that planets should obviously be l...
parseInt vs unary plus, when to use which?
...ail since the x and e are treated as non-numerical components (at least on base10).
The unary + will convert them properly though.
parseInt('2e3',10) === 2; //true. This is supposed to be 2000

parseInt("0xf", 10) === 0; //true. This is s...
Set default syntax to different filetype in Sublime Text 2

...u can use the built-in filter function to filter dictionaries, lists, etc. based on specific conditions.
filtered_dict = dict(filter(lambda item: filter_str in item[0], d.items()))
The advantage is that you can use it for different data structures.

Is the creation of Java class files deterministic?
...not matter. However, we find it beneficial to have javac's output not vary based on implementation details of system classes .
This pretty clearly illustrates the issue: The compiler is not required to act in a deterministic manner, as long as it matches the spec. The compiler developers, however,...

Do git rebase -i <sha before the branches diverged> this will allow you to remove the merge commit and the log will be one single line as you wanted. You can also delete any commits that you do not want any more. The reason th...

How do MySQL indexes work?
...ok (that's where the name came from):
Let's say you have a book about databases and you want to find some information about, say, storage. Without an index (assuming no other aid, such as a table of contents) you'd have to go through the pages one by one, until you found the topic (that's a full t...
