Female hurricanes being 'quite a bit deadlier' than male hurricanes may well be surprising but it has equal probability with the event that male hurricanes are 'quite a bit deadlier' than female hurricanes. I definitel

Surprisingly, if you assume a uniform distribution of deadliness independent of the names, you actually find that it's more likely that either 1 or 2 is true than that 3 is true Right, but if you are a statistician what you should ca

I was just saying M+N ≠ M×N, and that solutions that forces M×N are bogus. Agreed. I was clarifying that converting your code to use visitors does not force an order of magnitude increase in the amount of code. If you start out with O(M

With M objects and N behaviours, it's okay to write M plus N pieces of code. With the Visitor pattern as I saw described, I have to write M times N pieces of code. It's actually the same amount of code in either case. With N dif

for every single subtype you add, you still need to add a case to each of your visitors. Why is this a problem? If you have N visitors, that's N different behaviors for every type, and you'll have to define those N behaviors for

Are you trolling here, or are you really implying that the JVM is bad? Could you elaborate? I consider the JVM to be the best part of programming in Java. The JVM is fast, lets you write very portable code, and it gives you a great debuggin

I personally would like to see a rule where each car gets X amount of fuel (adjusted in BTUs) per race. I think the article mentioned exactly that: To enforce this focus, the 2014 regulations limit the total fuel consumption for an entir

I agree. This is going to affect Rust's adoption if they aren't careful. People are hesitant to write tutorials, documentation, or code that may need to be rewritten later. But I still give Rust a pass on this for the time being.

Huh. I didn't realize PyPy was so much larger than CPython. I was aware of the ridiculous size of emscripten's output. When I experimented with emscripten a couple months ago, "Hello World" in C produced about 2000 lines

Go sure is easy to get started with, but it would have to be 20 times better than it is to make me give up the JVM. I like Rust because it gives you control (like C++) but does so carefully (unlike C++). In ten years, Go should be a great

The ability to work well with others is a skill that benefits any workplace. An obvious way to gauge this is to contact the candidate’s references. But, why not take it a step further and dig into a candidate’s social media profiles? Ehh.

The PyPy project did not reimplement the entire Python standard library. The goal of PyPy is to provide a drop-in replacement for the canonical CPython interpreter . Right now, PyPy is (very) compatible with existing Python 2.7.3 code.[1]

The quoted 139 MB includes the full Python standard library, which certainly accounts for a majority of that size. repl.it also compiles the entire Python standard library, so why should the two be significantly different in size?

repl.it uses a version of CPython compiled with emscripten[1], so the version in the article should be similar in size. 1: https://github.com/replit/empythoned

I'm not sure how you define hacking. Web-scraping is not gaining unauthorized access to an otherwise inaccessible system. Anything you can see with your eyes in a browser is out in the open. And you can adjust a scraper's schedule

Slightly off topic, but something I've been curious about. Go decided on garbage collection to manage memory. Why do so few languages offer something like C++'s RAII?[1] In C++, when you define a class, you define the constructor(

I meant, you have a number of regular expressions, and each gets compiled (e.g. by calling re.compile in Python), so you have one DFA per regex. At least in Python, there are also transient objects created whenever you match something with

I'm not surprised the hand-written version is faster. You need to store an object for each regex. If these objects are DFAs, for example, then there is a considerable amount of overhead storing the graph to represent the DFA. The hand-

Right, and comments and documentation serve different purposes. But appropriate docstrings will greatly reduce the need for comments.

Yeah. This is my biggest gripe working with dynamically-typed languages, especially if the project is at all large. If I have SublimeText or Vim, I'll be equally productive in Python as I'd be in Java. But give me Eclipse/Int
