You would have to spam off-topic and irrelevant stuff dozens of times to get banned back in the days.

If you selectively apply rules to censor stuff you don't like, you can find anything to be a violation of some rule. For example, I found your reply about how language policing is good to be off topic and poor quality.

Should I report you and get you banned? No. Because this is what free speech is about. We aren't living in North Korea.

Probably need to handle the resize event to store the terminal width and height (I think that's WINCH signal?) and then add a conditional to only print at a position if position is less than the terminal size (need to check both width and height).

Also it's probably not "computionally expensive", it's just the terminal drawing that's the bottleneck, try benchmarking it with and without drawing.

>>56538256
Dive Into Python

I'm developing something in Python that requires me to coerce several different forms of data to a single type. There are two approaches:

>Basic class, functions for coercion

class Book():
    """ A generic book."""
    def __init__(self, title, author, year):
        self.title = title
        self.author = author
        self.year = year
        

def story_to_book(story):
    """ Convert a some_module.Story object to a Book."""
    # Extract details buried in the object
    info = story.data['info']
    title = info['title']
    author = [author['name'] for author in info['authors']]
    year = min(story['years_published']) # get first year published

    return Book(title, author, year)

def poem_to_book(poem):
    """ Convert a another_module.Poem object to a Book. """
    # etc.
    
# Load up bookshelf 
bookshelf = []
for story in magazine:
    bookshelf.append(story_to_book(story))
for poem in poetry_collection:
    bookshelf.append(poem_to_book(poem))
for # etc.

> More complex class, in-instance coercion

class Book():
    """ A generic book."""
    def __init__(self, text):
        if isinstance(text, some_module.Story):
            self.initialise_from_story(text)
        elif isinstance(text, another_module.Poem)
            self.initialise_from_poem(text)
        elif # etc for all formats
    
    def initialise_from_story(self, story):
        """ Initialise from a some_module.Story object. """
        info = story.data['info']
        self.title = info['title']
        self.author = [author['name'] for author in info['authors']]
        self.year = min(story['years_published'])
    
    def initialise_from_poem(self, poem):
        """ Initialise from an another_module.Poem object. """
        # etc
        
# Load up bookshelf
bookshelf = []
for story in magazine:
    bookshelf.append(Book(story))
for poem in collection:
    bookshelf.append(Book(poem))
for # etc.

Which of these is more pythonic?

Fair enough though, I also suspected the second one, my only worry was that it would make the class a bit 'heavy' (code-wise and performance-wise) if there's many different possible types for `text`.

When you get to a certain level of complexity, you can't hold the whole program in your head at once without abstracting (if you disagree, you haven't written a big system)
When this happens, you will write more code that doesn't take into account some other state in the program, and you'll end up with bugs that are hard to deal with, and with enough time, you end up with your whole system being in jeopardy of having some pretty bad systemic issues.

What do you think about a program like beets (http://beets.io/) made for video (movies, tv, etc)?

It could add tags for production staff + actors, download subtitles, understand seasons and episodes of series, organize + rename on disk.

It could also support automatically making a low-bitrate copy of everything for streaming, importing DVDs and BluRays raw or encoded, etc.

If you had access to Google's Content ID API used on YouTube, you could do fingerprinting like with MusicBrainz for audio, but I don't think any public databases like that exist. So it would probably be driven by heuristics for identifying content, walking the user through decisions with an interactive command line UI like beets.

>>56539580

>>56539627
The semantic is absolutely the same.
Its just syntax that is changed, hence syntatic sugar.
Dosent mean it is a bad thing, since most people are used the point operator from other languages(outside of people who only use Haskell).

what OS does /dpt/ use for efficient cross-platform programming and compiling?

>>56539785
syntactic sugar is good because it allows for conciseness and prettyness

>>56539785
By that logic everything is just syntactic sugar for assembly.

Today I started working through the AngularJS Testing Cookbook.

It goes over testing using Jasmine, Protractor, Karma, and Testem. It also gets into automating using both grunt and gulp.

My test coverage on my work projects sucks, so I'm trying to improve it so that I can use it as a marketing tool to get other clients. They don't really understand what test coverage is, but if I can say something like "all of my projects have >90% test coverage for QA/QC assurance", they'll eat that shit up.

Git sucks. There, I said it.

Now that I succeeded in irritating most people, let me explain: Git is an error prone overkill for most small and medium sized projects.

Remember, Git was created to handle Linux development; most projects have a single relationship with the remote server. So, first, it’s an overkill to use, like shooting pigeons with a Cruise missile.

Second, because of its power, it’s extremely complex and makes it really easy to shoot yourself in the foot.

Most version control systems need a page or two to explain the basic commands. The Pro Git book is 550+ pages long.

So why, you, as a developer would use Git? What happen to "the best tool for the job"? What happened to KISS (not the rock band)?

Is it because you want to look cool? Or you think your project is going to be as large one day as the Linux kernel? Or your company is forcing you to?

I apologize for my first post being a rant, but recently I was forced to use Git in a new repository and it has been nothing but pain, for almost every simple step my old trusty GitHub GUI started throwing errors.

Looking online, it’s like a rash – it’s not only me getting into issues. So the problem is deeper, I believe with the model itself. We need a simpler CVS; any suggestions?

>>56540157
>Git sucks. There, I said it.
Wow, what a revolutionary.

>>56540111
That's the dirty little secret though, isn't it?
Usability is, of course, what makes dollars happen, and "if it works, why write tests? It's already passed the user test".
But for a competitive differentiator, being able to point to actual statistics across my repos, where others might be too cowardly to post that kind of thing, it can make a customer feel like you're really taking care of them and watching their back. They might even be willing to sacrifice some usability for that kind of assurance.

How hard is add *, commit, push? You will rarely do anything else.

>So why, you, as a developer would use Git? What happen to "the best tool for the job"? What happened to KISS (not the rock band)?

Because a lot of other people using git posts shit to stackoverflow. The larger base you have to burn through questions and answers, the less likely you are to run into a situation which can't be solved by a simple search.

It gets to five, and then decrements to four, and increments to five again at the end of the iteration. Repeat.

how does

  #include <iostream>
  int main()
  {
    for(int i = 1; i <= 100; ++i)
    {
      std::cout << i << '\r'; // return to beginning of line for overwriting with "Fizz" or "Buzz"
      if(i % 3 == 0) std::cout << "Fizz";
      if(i % 5 == 0) std::cout << "Buzz";
      std::cout << '\n';
    }
    return 0;
  }
