What is the JavaScript equivalent of var_dump or print_r in PHP?

I just recently started looking at dump files to help me analyze crashes of the w3wp process on our production environment at work...

And I would like to know, what are the differences between a minidump and a fulldump file ?

For some reason I can&#39;t find a way to get the equivalents of sqlite&#39;s interactive shell commands:

    .tables
    .dump

using the Python sqlite3 API. 

Is there anything like that?

I&#39;m trying to restore my dump file, but it caused an error:

Is there a solution? I searched, but I didn&#39;t get a clear answer.

I need to save the whole output of [Screen][1] to a file to check later all the content.

The reason is that I&#39;m dumping a flash memory through a serial port, using Screen to interface with it. I would like to save it to a file to check memory structure.

I&#39;ve tried:

    $: screen /dev/ttyUSB0 115200 &gt;&gt; foo.txt
    $: screen /dev/ttyUSB0 115200 | tee foo.txt

And I&#39;ve also tried to use bufferfile from screen, but I don&#39;t understand how to use it.

Is there an easy way?

I am trying to log a long array so I can copy it quickly in my terminal. However, if I try and log the array it looks like:

    [&#39;item&#39;,
     &#39;item&#39;,
      &gt;&gt;more items&lt;&lt;&lt;
      ... 399 more items ]

Is it possible to get which conf the nginx is using only from a running nginx process?

To get the conf file path. sometimes `ps aux` reveal it, sometimes it doesn&#39;t. It might be just something like `nginx: master process /usr/sbin/nginx` (same as `/proc/PID/cmdline`)

1. So is `nginx -V` the only solution?
2. From [this question](https://serverfault.com/a/436239/59379), is it possible to dump conf data structure from nginx process directly? Or at least dump the conf file path?

I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array.

I couldn&#39;t have phrased it better than the person that posted [the same question here][1].

But to keep it original, I&#39;ll phrase it my own way: suppose I have a string `&quot;00A0BF&quot;` that I would like interpreted as the

    byte[] {0x00,0xA0,0xBf}

what should I do?

I am a Java novice and ended up using `BigInteger` and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple.

Is it possible to create a Dump of SQL commands from a Microsoft Access database? I hope to convert this MDB file into a MySQL database for importing so I don&#39;t have to go through the CSV step.

I would expect even an MSSQL dump file to still contain workable SQL commands, but I know nothing of MSSQL, please let me know.

How can I convert an MDB (Access) file to MySQL (or plain SQL file)?

My code creates a dictionary, which is then stored in a variable.
I want to write each dictionary to a JSON file, but I want each dictionary to be on a new line.

My dictionary:

    hostDict = {&quot;key1&quot;: &quot;val1&quot;, &quot;key2&quot;: &quot;val2&quot;, &quot;key3&quot;: {&quot;sub_key1&quot;: &quot;sub_val2&quot;, &quot;sub_key2&quot;: &quot;sub_val2&quot;, &quot;sub_key3&quot;: &quot;sub_val3&quot;}, &quot;key4&quot;: &quot;val4&quot;}

Part of my code:

    g = open(&#39;data.txt&#39;, &#39;a&#39;)
    with g as outfile:
      json.dump(hostDict, outfile)

This appends each dictionary to &#39;data.txt&#39; but it does so inline. I want each dictionary entry to be on new line. 
Any advice would be appreciated.

Is there a library that will recursively dump/print an objects properties?  I&#39;m looking for something similar to the [console.dir()][2] function in Firebug.

I&#39;m aware of the commons-lang [ReflectionToStringBuilder][1] but it does not recurse into an object. I.e., if I run the following:

    public class ToString {
        
        public static void main(String [] args) {
            System.out.println(ReflectionToStringBuilder.toString(new Outer(), ToStringStyle.MULTI_LINE_STYLE));
        }
        
        private static class Outer {
            private int intValue = 5;
            private Inner innerValue = new Inner();
        }
        
        private static class Inner {
            private String stringValue = &quot;foo&quot;;
        }
    }

I receive:

&gt; ToString$Outer@1b67f74[
&gt; intValue=5  
&gt; innerValue=ToString$Inner@530daa
&gt; ]

I realize that in my example, I could have overriden the toString() method for Inner but in the real world, I&#39;m dealing with external objects that I can&#39;t modify.

I&#39;m writing a crawler which uses Hpricot. It downloads a list of strings from some webpage, then I try to write it to the file. Something is wrong with the encoding:

    &quot;\xC3&quot; from ASCII-8BIT to UTF-8

I have items which are rendered on a webpage and printed this way: 

    D&#195;&#169;veloppement

the `str.encoding` returns `UTF-8`, so `force_encoding(&#39;UTF-8&#39;)` doesn&#39;t help. How may I convert this to readable UTF-8?

I have a dump file with a `.SQL` extension (in fact it is a plain-text SQL file). I want to restore it into my created databases. I am using [pgAdmin III][1], and when I use its &quot;Restore Wizard&quot; it does not highlight the button &quot;Restore&quot;. Instead it is expecting a `.backup` file extension.

I tried using shell the commands for restoring the dump, but it still didn&#39;t work.

I am a newbie at this. If anybody could help me I would be obliged.

Edit
----

I used following command to the Shell SQL Pane of PostGres while sitting at the newTestDB.

    newTestDB-# \i E:\db-rbl-restore-20120511_Dump-20120514.sql

It still gave the same error (&quot;Permission Denied&quot;).

After elevating permissions it just shows me the default tables of PostgreSQL:

          List of tablespaces
    Name       |  Owner   | Location
    -----------+----------+----------
    pg_default | postgres |
    pg_global  | postgres |
    
    (2 rows)

 I don&#39;t know what to do for importing/restoring database from an SQL file.
