   This is due to PEP 448 "Additional Unpacking Generalisations" [1], which was approved with effect from Python 3.5. Other examples: x, y, *r, z = range(7) print("x: {}, y: {}, r: {}, z: {}".format(x, y, r, z))

   I'd be interested to see what the fake "fact" was in your post, on case I had mistakenly believed too.

   Perhaps "fractional" is the wrong word because has a literal meaning which probably isn't true if you compare calling a std::function vs calling a function directly within a template (although you still need to call that temp

   I was about to suggest this too. It's like a more general version of stacking, since you have multiple levels, and much more automatic (but you can drag the tabs into a different tree structure if you want). I think it would solve the

   Or you can use std::function. It's fractionally less efficient but much easier to understand and doesn't all have to go in the header (and only needs C++11): void addListener(std::function<int(Button*)> cb)

   Boost signals also handles multiple (or zero) callbacks associated with a single signal. I'm not sure but I believe it also allows calling the slot at a later point from a message pump – certainly Qt's signals and slots do. A more

   I think you read the comment disingenuously. It is pretty clearly implying "...but it will have that effect because it neutralises the problem that the article is all about".

   It depends on what you count as a "major implementation".

   Surprisingly, pure functional components are called even when their props haven't changed so PureComponent is not "in between" but "even more" than functional components. As for regular components, you can override

    I absolutely agree with you. This makes me very skeptical about the proposed feature in React, called "hooks", which is linked to in the article. It lets you add state to your functional components, and it looks like you end up bu

    > `uint8_t` and `char` are not guarenteed to be the same type Remember that `char`, `signed char` and `unsigned char` are the different types, even though `char` takes the same range of values as either `signed char` or `unsigned char`.

    I remember having exactly the same experience, including the anticipation that I would benefit from it the way I would from Design Patterns. For most of the refactorings in the book, a bullet point in a list would've seemed a bit exces

    Yes. Even .uk is a domain - that's why it can be called a top-level domain.

    Sorry for the nitpick, but things like .com and .uk are TLDs (top-level domains). Something like microsft.com is simply a domain.

    For Mercurial, you need to totally abandon the idea that a branch is stored by reffing a commit, and the branch is implicitly defined as the ancestor commits of that head. Instead, every single commit has a branch name baked into it as a si

    In case you haven't already heard of it, LyX [1] does exactly that and it's phenominal. As an added bonus, when you move your cursor out of the equation it goes from a graphical almost-right visualisation to a proper LaTeX-generat

    I have a different workflow in TortoiseHg than ufo. In your terminology, I only consider revisions that have been pushed as being baked, while unpushed revisions are the clay. We already have tools to manipulate revisions, while the index

    The problem that black had last time I saw it on hacker news is that it only inserts whitespace. Unlike braces-and-semicolon languages, that is sometimes not enough to format code well. For example, given the following line: x[1][4] =

    Any time I have felt the need for something like goto, I have found that need served well by a function with multiple return statements. You're right that it can't simulate jumping into a block though, but that seems like a feat

    Coalescing those four lines onto one is fine, but writing: map(invert, (node.right, node.left)) is definitely not simpler than: invert(node.right), invert(node.left)

    I find WSL to be pretty amazing. I can compile and test Linux binaries on my Windows laptop, and I can even directly use the same directory of source code as I use to build Windows binaries. I haven't noticed a difference in compilatio

    The reason this update was paused was that it deleted user files (subdirectories of your user folder that it thought were empty and useless but actually weren't). The model you suggest might be a good idea but it wouldn't have hel

    It's subjective of course, but for me buffalo is more satisfying because the noun, adjective and verb are all totally different words, whereas for police they're all variants of the same root.

    It is not true that UTF8 is the right design "everywhere". Perhaps it is the right design when you have strings that are stored and later read by various programs, but it's not necessarily right for in-memory strings. Python

    This is because Python 3.5 and earlier used the old non-Unicode Windows API to access the console. This was fixed in Python 3.6: https://docs.python.org/3/whatsnew/3.6.html#whatsnew36-pep52...

    That looks promising; pity it doesn't put the file/directory name in the graph. It looks like KDirStat and its successor QDirStat have a split pane view, with file names at the top and anonymous rectangles representing file sizes

    How can you mention those tools without also noting their most famous on-screen appearance: the "hacking" scene from Jurassic Park :-) This is almost the opposite of what you're asking for, but I am reminded of a rather more
