`blank` targets an existing frame or window called &quot;blank&quot;. A new window is created only if &quot;blank&quot; doesn&#39;t already exist.

`_blank` is a reserved name which targets a new, unnamed window.

In short, use `target=&quot;_blank&quot;` it always open a new window but use `target=&quot;blank&quot;` it will open a new window at the first time and this window will be reused after the first.

Both target=&quot;_blank&quot; &amp;&amp; target=&quot;blank&quot; will open **new window or tab**.
The difference is 
 
    target=&quot;_blank&quot;

 On every click, it will open in a **new window**.

    target=&quot;blank&quot;
On another (Multiple) clicks, it will Open in the **same window** that opened for the first click (reuses the same tab).
  *It reuses the same tab for all the linked documents with attribute =&quot;blank&quot;*

I&#39;m trying out Python 3.6. Going through new code, I stumbled upon this new syntax:

    f&quot;My formatting string!&quot;

It seems we can do things like this:

    &gt;&gt;&gt; name = &quot;George&quot;
    &gt;&gt;&gt; print(f&quot;My cool string is called {name}.&quot;)
    My cool string is called George.

Can anyone shed some light on the inner workings of this? In particular what is the scope of the variables that an f-prefixed string can take?

I couldn&#39;t find a place for me to change the working directory in Jupyter Notebook, so I couldn&#39;t use the pd.read_csv method to read in a specific csv document.

Is there any way to make it? FYI, I&#39;m using Python3.5.1 currently.

Thanks!

Since I approached the web programming, to open a link in a new window I always used 

    target=&quot;blank&quot;

but most of the time, here and in the rest of the web I have ever seen use:

    target=&quot;_blank&quot;



Both forms work (of course), but I do not know the difference between the two versions and they do not know what the correct way (and why)....

I&#39;m struggling to find documentation or examples of implementing an upload progress indicator using [fetch](https://github.com/github/fetch). 

[This is the only reference I&#39;ve found so far](https://jakearchibald.com/2015/thats-so-fetch/), which states:

&gt; Progress events are a high level feature that won&#39;t arrive in fetch for now. You can create your own by looking at the `Content-Length` header and using a pass-through stream to monitor the bytes received.
&gt;
&gt; This means you can explicitly handle responses without a `Content-Length` differently. And of course, even if `Content-Length` is there it can be a lie. With streams you can handle these lies however you want.

How would I write &quot;a pass-through stream to monitor the bytes&quot; sent? If it makes any sort of difference, I&#39;m trying to do this to power image uploads from the browser to [Cloudinary](http://cloudinary.com/documentation/image_upload_api_reference).

**NOTE**: I am ***not*** interested in the [Cloudinary JS library](https://github.com/cloudinary/cloudinary_js), as it depends on jQuery and my app does not. I&#39;m only interested in the stream processing necessary to do this with native javascript and Github&#39;s `fetch` polyfill.

I have a strange problem with the Jenkins HTML Publisher plugin, wherein all the fancy CSS I have added to the report is stripped out when viewed in Jenkins. If I download the report to local, I am able to see the CSS formatting. Is there a setting in Jenkins which allows CSS to be viewed?

i&#39;ve embed a YouTube video on my website but the trouble is that i need the height to automatically adjust based on the width and the aspect ratio of the video. So if my width is 1280, my height should be 720 if the video is 16:9.
I&#39;ve tried using &#39;VW&#39; and &#39;VH&#39; units but these don&#39;t seem to work with an iframe. My width is already set proportionally.

My code is below:

    &lt;iframe style=&quot;margin-right: 1%; margin-left: 1%;&quot; width=&quot;98%&quot; height=&quot;&quot; src=&quot;https://www.youtube.com/embed/HwzQbfde-kE&quot; frameborder=&quot;0&quot;&gt;&lt;/iframe&gt;

After trying to find an example where the `FloatingActionButton` floats at its standard bottom-right screen position with no results, I come to you if you could provide one because it seems to be a normal button without floating to that corner by default.

Am I supposed to make it float by setting custom CSS rules?
Material-UI docs doesn&#39;t mention any property about floating [Material-UI FloatingActionButton documentation][1].

How would one put a link on a button with bootstrap?

there are 4 methods in the bootstrap documentation:

    &lt;a href=&quot;#&quot; class=&quot;btn btn-info&quot; role=&quot;button&quot;&gt;Link Button&lt;/a&gt;
    &lt;button type=&quot;button&quot; class=&quot;btn btn-info&quot;&gt;Button&lt;/button&gt;
    &lt;input type=&quot;button&quot; class=&quot;btn btn-info&quot; value=&quot;Input Button&quot;&gt;
    &lt;input type=&quot;submit&quot; class=&quot;btn btn-info&quot; value=&quot;Submit Button&quot;&gt;

The first one doesn&#39;t work for me, no button shows, just the text with the link, have a feeling its the theme im using.

The second one shows the button which is what i want, but whats the code make the button link to another page when clicked?

Cheers

How to put a link on a button with bootstrap?

I&#39;m rendering a link with react:

    render: -&gt;
      `&lt;a className=&quot;upvotes&quot; onClick={this.upvote}&gt;upvote&lt;/a&gt;`

Then, above I have the upvote function:

    upvote: -&gt;
      // do stuff (ajax)

Before link I had span in that place but I need to switch to link and here&#39;s the trouble - every time I click on `.upvotes` the page gets refreshed, what I&#39;ve tried so far:

***event.preventDefault() - not working.***

    upvote: (e) -&gt;
      e.preventDefault()
      // do stuff (ajax)

***event.stopPropagation() - not working.***

    upvote: (e) -&gt;
      e.stopPropagation()
      // do stuff (ajax)

***return false - not working.***

    upvote: (e) -&gt;
      // do stuff (ajax)
      return false

I&#39;ve also tried all of the above using jQuery in my index.html, but nothing seems to work. What should I do here and what I&#39;m doing wrong? I&#39;ve checked event.type and it&#39;s `click` so I guess I should be able to avoid redirect somehow?

Excuse me, I&#39;m a rookie when it comes to React.

Thank you!

Is there a way to let a Link, written in githubs markdown, open in a new tab?
All posts I have found related to this suggests to use HTML and `target=&quot;_blank&quot;`, which is fine with me, but that doesn&#39;t work.
For example this link:

    &lt;a href=&quot;http://stackoverflow.com&quot; target=&quot;_blank&quot;&gt;Go&lt;/a&gt;

Does not open in a new tab.
I&#39;m no interested in replies for all kind of different markdown syntaxes, but only in a solution that will work when I write my markdown on github.

Using suggested method:

I was wondering if there is a way to wrap a `Link` element from `&#39;react-router&#39;` in an HTML `button` tag using react.

I currently have `Link` components to navigate pages in my app, but I would like to map that functionality to my HTML buttons.
