Hard tabs use the tab character, http://en.wikipedia.org/wiki/Tab_key#Tab_characters

Soft tabs are just spaces. Soft tabs are usually either 2 or 4 spaces, depending on convention.

If you set your editor to use &quot;soft tabs,&quot; when you press the Tab key on your keyboard your editor will insert spaces instead of the tab character.


Hard tabs are the equivalent of using the tab key to tab your code while soft tabs are spaces added in to emulate a tab either manually or via a code editor like Sublime Text. There are some who believe that soft tabbing is better for readability for larger teams that use different text editors since some editors will give different spacing for hard tabs, but I think you can use either one as long as you stick to one and use it consistently. In the end, this mostly comes down to personal preference.

Where does mysql store data? I found out (by using mysql&gt;SELECT @@datadir ) that it&#39;s in var/lib/mysql - but that can&#39;t be it. I have a quite big database (4 GB) called &#39;bot&#39;, but all the files in the &#39;bot&#39; subdirectory (var/lib/mysql/bot) have only 280KB. Where is the rest?

One more thing - 99% of the database&#39;s size is a text column in one of the tables - I know that mysql stores it in separate files, but does it create one file per record?

I found a big file in the var/lib/mysql directory named ibdata1 - its size is over 8GB - what is it? (btw, there are other databases as well in the var/lib/mysql directory).

I made a new view controller in Storyboard and made a new .Swift file that inherits `UIViewController`. However, my `viewDidLoad()` is not being called.

What do I need to do to connect my view controller in my story board to my .swift code so `viewDidLoad()` is called?

I see there&#39;s this: https://stackoverflow.com/questions/19370208/how-to-connect-storyboard-to-viewcontroller

However, in a default project, FirstViewController(storyboard) doesn&#39;t have FirstViewController in that box, it is empty, yet `viewDidLoad()` is still called. It doesn&#39;t make sense.

When reading source of D3.js I saw `x &gt;= x` pattern. If it is for detecting NaNs among numbers, why not just `isNaN(x)` or `x == x`?

[Source, where I encountered it](https://github.com/mbostock/d3/blob/master/d3.js#L52-L67): 


    d3.min = function(array, f) {
      var i = -1, n = array.length, a, b;
      if (arguments.length === 1) {
        while (++i &lt; n) if ((b = array[i]) != null &amp;&amp; b &gt;= b) {
          a = b;
          break;
        }
        while (++i &lt; n) if ((b = array[i]) != null &amp;&amp; a &gt; b) a = b;
      } else {
        while (++i &lt; n) if ((b = f.call(array, array[i], i)) != null &amp;&amp; b &gt;= b) {
          a = b;
          break;
        }
        while (++i &lt; n) if ((b = f.call(array, array[i], i)) != null &amp;&amp; a &gt; b) a = b;
      }
      return a;
    };

x &gt;= x pattern in JavaScript

I read through the [TypeScript Coding guidelines][1]

And I found this statement rather puzzling:
&gt; Do not use &quot;I&quot; as a prefix for interface names

I mean something like this wouldn&#39;t make a lot of sense without the &quot;I&quot; prefix

    class Engine implements IEngine

Am I missing something obvious?

Another thing I didn&#39;t quite understand was this:

&gt; **Classes**
&gt; 
&gt; For consistency, do not use classes in the core compiler pipeline. Use
&gt; function closures instead.

Does that state that I shouldn&#39;t use classes at all?

Hope someone can clear it up for me :)

Confused about the Interface and Class coding guidelines for TypeScript

I love the [Airbnb JavaScript Style Guide][1]. Most of the rules also apply to TypeScript, but of course it doesn&#39;t cover specific TypeScript language features. 

I have also found the [Microsoft TypeScript Coding Guidelines][2] but they are for the TypeScript project itself, not for projects that **use** TypeScript. 

Finally I found the [TypeScript Style Guide by Platypi][3] but it&#39;s not as detailed as I&#39;d like it to be. Is there another (official?) TypeScript Style Guide that I missed? Or are the two I listed the only ones that exist?

So, reStructuredText is
[the recommended way](https://www.python.org/dev/peps/pep-0287) for Python code
documentation, if you try hard enough, you can
[find in the sphinx documentation](http://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#python-signatures)
how to normalize your function signature documentation. All given examples are
single-line, but what if a parameter description is multi-line like the following
?

    def f(a, b):
        &quot;&quot;&quot; Does something with a and b

        :param a: something simple
        :param b: well, it&#39;s not something simple, so it may require more than eighty
                  chars
        &quot;&quot;&quot;

What is the syntax/convention for that ? Should I indent or not ? will it break reSTructuredText rendering ?


Multi-line description of a parameter description in python docstring

I know that JavaScript (and thus TypeScript) support the omission of semicolons in many cases. Nevertheless I want to add semicolons to be unambiguous as suggested in [TypeScript Deep Dive](https://basarat.gitbooks.io/typescript/content/docs/styleguide/styleguide.html#semicolons)

However I cannot find a guide that lists where to use semicolon. For example look at the following code

    class Person {
      private name: string; // A
    
      constructor(name: string) {
        this.name = name;
      }; // B

      public add = () =&gt; {
        return &quot;C&quot;;
      }; // C
    }; // D

I&#39;m fairly sure to use a semicolon at *A*. But what about *B*, *C*, *D* and all the other cases not covered by my example?

I&#39;m not asking where to omit semicolon but where to add them. An answer like *always* does not fulfill my needs since I cannot add a `;` after `public`. I want to know where exactly to put semicolon.

When is it appropriate to use a semicolon?

Trying to understand the subtleties of modern Unicode is making my head hurt. In particular, the distinction between code points, characters, glyphs and graphemes - concepts which in the *simplest* case, when dealing with English text using ASCII characters, all have a one-to-one relationship with each other - is causing me trouble.

Seeing how these terms get used in documents like Matthias Bynens&#39; [JavaScript has a unicode problem][1] or Wikipedia&#39;s piece on [Han unification][2], I&#39;ve gathered that these concepts are not the same thing and that it&#39;s dangerous to conflate them, but I&#39;m kind of struggling to grasp what each term *means*.

The Unicode Consortium offers a [glossary][3] to explain this stuff, but it&#39;s full of &quot;definitions&quot; like this:

&gt; ***Abstract Character***. A unit of information used for the organization, control, or representation of textual data. ...
&gt;
&gt; ...
&gt;
&gt; ***Character***. ... (2) Synonym for abstract character. (3) The basic unit of encoding for the Unicode character encoding. ...
&gt;
&gt; ...
&gt;
&gt; ***Glyph***. (1) An abstract form that represents one or more glyph images. (2) A synonym for glyph image. In displaying Unicode character data, one or more glyphs may be selected to depict a particular character.
&gt;
&gt; ...
&gt;
&gt; ***Grapheme***. (1) A minimally distinctive unit of writing in the context of a particular writing system. ...

Most of these definitions possess the quality of sounding very academic and formal, but lack the quality of *meaning anything*, or else defer the problem of definition to yet another glossary entry or section of the standard.

So I seek the arcane wisdom of those more learned than I. How exactly do each of these concepts differ from each other, and in what circumstances would they not have a one-to-one relationship with each other?

I&#39;m looking at a piece of Java code right now, and it takes a path as a String and gets its URL using `URL resource = ClassLoader.getSystemClassLoader().getResource(pathAsString);`, then calls `String path = resource.getPath()` and finally executes `new File(path);`. 

Oh, and there are also calls to `URL url = resource.toURI();` and `String file = resource.getFile()`.

I&#39;m totally confused right now - mostly because of the terminology, I guess. Can someone please walk me through the differences, or provide a few links to Dummy-proof material? Especially URI to URL and *Resource to File*? To me, it feels like they should be the same thing, respectively...

The difference between **`getFile()`** and **`getPath()`** is explained here: [What&#39;s the difference between url.getFile() and getpath()?](https://stackoverflow.com/a/11928221/2018047) (Interestingly they both seem to return Strings, which probably adds a whole lot to my state of mind...)

Now, if I have a locator that references a class or package in a jar file, will those two (i.e. path an file strings) differ?

`resource.toString()` would give you `jar:file:/C:/path/to/my.jar!/com/example/`, after all (note the exclamation mark).

Is the difference between **URI** and **URL** *in Java* that the former doesn&#39;t encode spaces? Cf. [Files, URIs, and URLs conflicting in Java](https://stackoverflow.com/a/6818370/2018047) (This answer explains the *general, conceptual* difference between the two terms fairly well: [URIs identify and URLs locate;](https://stackoverflow.com/questions/176264/whats-the-difference-between-a-uri-and-a-url/1984225#1984225))

Lastly - and most importantly - **why do I need `File` object; why isn&#39;t a Resource (`URL`) enough?** (And is there a Resource object?)

Sorry if this question is a bit unorganized; it just reflects the confusion I have... :)

I&#39;m writing an explanation for some code for a course, and have been accidentally using the words `method` and `function` interchangeably. I decided to go back over and fix the wording, but ran into a hole in my understanding.

From what I understand, a subroutine is a `function` if it doesn&#39;t act on an instance of a class (its effect is restricted to its explicit input/output), and is a `method` if it operates on an instance of a class (it may carry out side effects on the instance that make it impure).

There&#39;s a [good discussion here][1] on the topic. Note that by the accepted answer&#39;s definitions, a static `method` should actually be a function because an instance is never implicitly passed, and it doesn&#39;t have access to any instance&#39;s members.

With this is mind though, shouldn&#39;t static `methods` actually be functions?

By their definition they don&#39;t act on particular instances of a class; they&#39;re only &quot;tied&quot; to the class because of relation. I&#39;ve seen a few good looking sites that refer to static subroutines as &quot;methods&quot; though ([Oracle][2], [Fredosaurus][3], [ProgrammingSimplified][4]), so either they&#39;re all overlooking the terminology, or I&#39;m missing something (my guess is the latter).

I&#39;d like to make sure I am using the correct wording.   
***Can anybody clear this up?***
