I&#39;ve always been a little confused about what&#39;s going on here:

    #include &lt;stdio.h&gt;

    int main() {  
        timeval tv;
        tv.tv_sec = 1;

        for (;;) {
            select(0, 0, 0, 0, &amp;tv);
            printf(&quot;%s\n&quot;, &quot;Hello World!&quot;);
        }
    }

Sorry if that doesn&#39;t compile, just wrote it as a quick example.

Code like this won&#39;t compile under gcc unless I add the keyword **struct** prior to the use of the struct timeval.  g++ on the other hand handles it fine as is.

Is this a difference between how C and C++ handle structures or is it just a difference in the compilers?  (I&#39;m very C++ oriented, and the use of struct in C on lines like this has always somewhat baffled me).



Why does C need &quot;struct&quot; keyword and not C++?

The documentation isn&#39;t especially clear&amp;mdash;&lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;T&lt;/kbd&gt; is to jump back in the tag stack, whereas &lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;O&lt;/kbd&gt; is to jump back to the previous cursor position. What&#39;s the difference between &lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;T&lt;/kbd&gt; and &lt;kbd&gt;CTRL&lt;/kbd&gt;+&lt;kbd&gt;O&lt;/kbd&gt;? They both appear to exhibit the same behavior.

In the Google Chrome console, if I type `fn` where `fn` is a function, then I get the code for `fn`. In the Node console, typing `require.resolve` simply prints out

    [Function]

Why don&#39;t I get the function definition?

Why doesn&#39;t the Node console display the function code?

Is there a way to write a delete/deleteAll query like findAll?

For example I want to do something like this (assuming MyModel is a Sequelize model...):

    MyModel.deleteAll({ where: [&#39;some_field != ?&#39;, something] })
        .on(&#39;success&#39;, function() { /* ... */ });

I have a script `foo.js` that contains some functions I want to play with in the REPL.

Is there a way to have node execute my script and then jump into a REPL with all the declared globals, like I can with `python -i foo.py` or `ghci foo.hs`?

How do I load my script into the node.js REPL?

How do you detect what environment an expressJS app is running in? (development, test, production?). There&#39;s nothing in `process.env` indicating an environment...

I&#39;m aware that you can declare variables in your configuration file under each environment, but that doesn&#39;t help if you are dynamically loading modules...
