Yes, itertools is great. But its stblib is still much lighter than Scala's and Ruby's. Actually, that seems to be the direction/principle of Python, where it is less inclined to add a helper function. "It has been discus

Here was one example I encountered a while back: https://stackoverflow.com/questions/952914/how-to-make-a-fla... In Python, it's `import itertools` and `list(itertools.chain.from_iterable(list2d))` or `[item

Saying Ruby/Scala have richer standard lib than Python isn't really a stab at Python. Like dragonwriter says, it shows that "Python expresses the concept fairly compactly in the core language without even resorting to stdlib&

While what you say is true, my small example shows that the code is longer in Python for solving the same problem, i.e. `my_list[0] if my_list else None` is longer than `my_list.headOption` or `my_list.first`. And we are talking about the b

That's a great example. And, yes, Javascript has a similar problem.

I know. It's strange to say that. But Scala's library is very very rich. Another example is that Scala offers a lot of ways to process a list like foldLeft, foldRight, unzip, headOption, lastOption, flatMap, groupBy, and many meth

by tanin 7y ago
Maybe I should have given the comparable example in Ruby, which is `array.first`. Even Scala offers `array.headOption`. Both are more succinct than Python's. The degree of richness and/or the height of abstraction seem lower in Py

One factor on why Python only saves 20%. Scala has a very rich standard library. Python doesn't. An example is: https://stackoverflow.com/questions/363944/python-idiom-to-r... Ruby would have been a better ex

The Scala result confirms my bias :P I love Scala because it strikes a great balance between being succinct and offering type safety. I wish you would use Ruby instead of Python. Python is strangely inconsistent. For example, Python doesn&#

This is such an awesome service. Congrats Everest (and team) for making it easier to make software more secure!

I might misunderstand the question here. Could you elaborate more why the complete grammar of Rust is important for writing a compiler (for any programming langugage) in Rust? I thought the question was about whether to write a compiler in

by tanin 8y ago
I find that Rust's syntax/ecosystem is much more modern and pleasant to use. Some examples are: pattern matching, immutable variable, better build and dependency system, and many more. There are some concepts like lifetime that yo

Playframework (with Scala) + Vue.js (with Typescript) + Heroku. It gives me a good balance on development speed over project's age and performance. I particularly like the balance of type safety and brevity. Learning curve is high for

For a non-strong-typed language, it's difficult to dive into the code after you haven't work on that codebase for a while. We were on a really old Mongoid (or carrierwave, or some other gem, can't remember), It was difficult

Coming from Ruby, I encountered this funny situation in Python. I was looking how to get first element of an array or get nil if the array is empty. Python library doesn't provide this kind of functionality. https://stackove

That's exactly what I have been doing `clang -S --emit-llvm <filename>`. Godbolt.org is even more handy!

LLVM is a great project. I'm writing a programming language based on it. It is so much easier because: (1) it's easier than writing machine code translation and (2) it's also easier than translating your code to C which woul

I understand what you mean, and it's definitely a trade off. Static typing requires all types to make sense together no matter how small the addition is. In dynamic typing, we can just add a class/object/field here and there
265.
by tanin 8y ago
Thank you. I think I have a good idea what it is now. It's a constraint of a field. But it goes a bit further to ensures that, for example, an author id refers to a valid entity.

> It does depend on how you write your code but favoring pure functions, pushing immutability to the edges of your programs allows you to refactor without fear. Dynamic typing is punitive if we make mistake (e.g. using the wrong architec

Is Spec simply a test? Or is it something more? I keep hearing about it, but it seems to be more than just a test case. Let's take a simple example. I have an object with the method named "get". But I call "fetch" i

For me, what competitive coding, or practice of it, improves 2 skills: (1) solve an algorithmic problems and (2) translate ideas into code quickly and correctly. The number 1 is not that essential. But the number 2 is somewhat essential for

From what I've seen, it seems to be the other way around. As we get better linearly (e.g. code faster), our income increases somewhat exponentially. So, it seems like a better strategy to try to earn more. Not to mention that having mo
