I am aware that nofollow links are specifically enforced so that search engine bots do not follow that link.

The reality is that this link attracts visitors and my theory is that a link, even if it has a nofollow for Google, for example, still has value, even if it is 1% compared to one without the nofollow.

Apart from this, what are the following values ​​for the rel attribute for because I don't see reliable information about it (the one that catches my attention is external).

I've only seen info here: http://www.w3schools.com/tags/att_a_rel.asp

But it doesn't explain if there are differences in SEO issues or browser behaviors.

I have created several links to https://japanpanda.com/ being nofollow (On other pages) and I have not seen any changes except improvements in referals.

I have found blocks of code like this:

with a as b:
    c = b.algo()

It would look like some dynamic similar to namespaces, but the following code

a = 1
with a as b:
    print a, b

returns the following error:

AttributeError: __exit__

So what is the keyword for with, and how does it work? What is the role of __exit__?

I am trying to create controls with code, I was able to create them but my problem is that when creating them they do not adopt my custom style that I am using with material design properties. I am attaching an image where I have created controls manually with xml design and they adopt the material design style without problems, but at the bottom I created 3 controls (Textview, EditText and RadioButton) with java code which have not adopted the style. The problem happens in Api 19 or lower, in Api 21 and up I don't have this problem.

I did everything they told me and I don't find results, it's still the same, I leave my code that I'm using.

package com.ejemplo.probandoo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.RadioButton;
import android.widget.RadioGroup;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ViewGroup hourButtonLayout = (ViewGroup) findViewById(R.id.radio_group);

    final RadioButton[] rb = new RadioButton[5];

    RadioGroup rg = new RadioGroup(this);
    //rg.setOrientation(RadioGroup.VERTICAL);
    for(int i=0; i<5; i++){
        rb[i]  = new RadioButton(this);
        rb[i].setText("foo bar");
        rb[i].setId(i + 100);
        rg.addView(rb[i]);
    }
    hourButtonLayout.addView(rg);
}}

That's my code and the result is the same it doesn't adopt my custom style:

I'm trying to do a currency format for my input, which I want to automatically format with thousands separator(",") and decimals; I tried with several plugins but they do not work for me.

function addCommas(nStr) {
        nStr += '';
        x = nStr.split('.');
        x1 = x[0];
        x2 = x.length > 1 ? '.' + x[1] : '';
        var rgx = /(\d+)(\d{3})/;
        while (rgx.test(x1)) {
                x1 = x1.replace(rgx, '$1' + ',' + '$2');
        }
        return x1 + x2;
    }

This adds commas to me, but only for the first unit of thousands :(

This example here works, but on a blur event, how do I run it on a keyup event.

$("#number").keyup(function() {

  this.value = parseFloat(this.value.replace(/,/g, ""))
                    .toFixed(2)
                    .toString()
                    .replace(/\B(?=(\d{3})+(?!\d))/g, ",");
});

I am using the javascript file API to read images using the readAsDataURL method and found that my images were always larger than their originals, in one case even 1MB larger.

This is the code I am using

$(function() {
  'use strict';
  $('#source').on('change', function(evt) {

    var reader = new FileReader();

    var file = evt.target.files[0];
    var reader = new FileReader();

    reader.onloadend = function() {
      $('#encoded').text('El tamaño codificado es ' + reader.result.length / 1024 + ' kb')
    }

    if (file) {
      $('#original').text('El tamaño original es ' + file.size / 1024 + ' kb')
      reader.readAsDataURL(file);
    }
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="source" type="file">
<div id="original"></div>
<div id="encoded"></div>

I don't know if I am missing something here or if there is some reason for this behavior. Does anyone know what could be the cause?
