The answer, so us lazy people can find it without following the link to the [Autolinked References and URLs section of the GitHub help](https://help.github.com/articles/autolinked-references-and-urls/#commit-shas):

    User/Project@SHA

For example:

    mojombo/god@be6a8cc1c1ecfe9489fb51e4869af15a13fc2cd2

Short SHAs work as well (as long as they are unique):

I&#39;ve done some research, and I seem to be missing one small part of this algorithm. I understand how a Breadth-First Search works, but I don&#39;t understand how exactly it will get me to a specific path, as opposed to just telling me where each individual node can go. I guess the easiest way to explain my confusion is to provide an example:

So for instance, let&#39;s say I have a graph like this:

![enter image description here][1]

And my goal is to get from A to E (all edges are unweighted).

I start at A, because that&#39;s my origin. I queue A, followed by immediately dequeueing A and exploring it. This yields B and D, because A is connected to B and D. I thus queue both B and D.

I dequeue B and explore it, and find that it leads to A (already explored), and C, so I queue C. I then dequeue D, and find that it leads to E, my goal. I then dequeue C, and find that it also leads to E, my goal.

I know logically that the fastest path is A-&gt;D-&gt;E, but I&#39;m not sure how exactly the breadth-first search helps - how should I be recording paths such that when I finish, I can analyze the results and see that the shortest path is A-&gt;D-&gt;E?

Also, note that I&#39;m not actually using a tree, so there are no &quot;parent&quot; nodes, only children.

How does a Breadth-First Search work when looking for Shortest Path?

I have the following simple code:

&lt;!-- begin snippet: js hide: false --&gt;

&lt;!-- language: lang-html --&gt;

    &lt;!DOCTYPE html PUBLIC &quot;-//W3C//DTD XHTML 1.0 Transitional//EN&quot; &quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&quot;&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot; xml:lang=&quot;en&quot;&gt;

    &lt;head&gt;
      &lt;title&gt;Live Feed&lt;/title&gt;

      &lt;meta http-equiv=&quot;content-type&quot; content=&quot;text/html; charset=UTF-8&quot; /&gt;

      &lt;style&gt;
        body {
          margin: 0px;
          padding: 0px;
        }
      &lt;/style&gt;
    &lt;/head&gt;

    &lt;body&gt;
      &lt;div style=&quot;background-color: #eeaabb; width: 250px; height: 100%; border-right: solid 1px #e1e1e1;&quot;&gt;
        I should be tall
      &lt;/div&gt;
    &lt;/body&gt;

    &lt;/html&gt;

&lt;!-- end snippet --&gt;

But the div doesn&#39;t get displayed with height being 100%. Why?

I&#39;d like to reference commits in other repos (in this case submodules) in the github issues of my main repo. Is it possible to do so without typing the full hyperlink in a way similar to how github creates a shortened hyperlink from the commit number?

There was a good link here about how the zip/tarball string is created

https://stackoverflow.com/questions/6334040/when-i-download-a-zip-from-github-what-is-the-hex-string-at-the-end-of-the-file

But I&#39;m looking at the GitHub APIv3 and I was curious if I&#39;m missing something.

1. Is there a way to get the zip/tarball link via an API call?

2. If not, is there a way I can build that string without using the git binary or library? Meaning, can I use various API calls to pull out th data a need and assemble to URL I need?

I know the second question is a little unreasonable for stackoverflow and this is a bit of a fun project for me, so I would prefer on the second question if you just kind of nudged me in the right direction as opposed to throwing down a code snippet. Or just told me if it was possible.

`git diff` actually runs a diff on all source code. How do I do this on a certain directory, so that I can view modifications on files underneath it?

Is there anything out there like Github that is for your own local server?  I am curious if there is like a PHP script or even a desktop client that mimics Github&#39;s functionality, I love Github but it would be nice to host on my own server.

Apologies if this isn&#39;t considered &quot;programming&quot; enough but generally only programmers use GIT and Github

## Update ##

First of all thanks for all the great suggestions, it is great to see there are options out there.  From what is posted here and from my googling I can say it looks like the best looking/most alike to Github solutions are coded in Ruby, which is great for some but I am a PHP kind of guy (for now).

Most of the PHP GIT viewers either are  outdated and abandoned projects or they just look like crap ( I realize I could fix them up to be more like Github) but I ran across something in PHP that looks promising so far.  It is called Glip it is on Github here https://github.com/patrikf/glip and to me it is the most attractive and easy to use solution I have found for PHP so far.  For the advanced Git user, it may not be enough but for me, I just wanted to be able to view a git repo and that provides that functionality.

Now my search still continues for the perfect solution, will I ever find it?  I hope so but, for now, this is we got.  I am considering writing my own, one that is attractive like Github and has other features like an Issue tracker for bug and feature requests.  All the ones I have seen so far are not so good

I fixed it for my repo by deleting the local tag and then doing a git fetch. This brought the updated tag. 

Is there are &quot;right&quot; way to update tags that may have changed on the remote? This is a simple tag, not signed or anything, created with &quot;git tag &lt;tagname&gt;&quot;

Is there any way to get git to give you a commit log for just commits that touched a particular _line_ in a file?

Like `git blame`, but `git blame` will show you the LAST commit that touched a particular line. 

I&#39;d really like to get a similar log of, not the list of commits to anywhere in the file, but just the commits that touched a particular line.

On http://github.com developer keep the HTML, CSS, JavaScript and images files of the project. How can I see the HTML output in browser?

For example this: https://github.com/necolas/css3-social-signin-buttons/blob/master/index.html

When I open this it doesn&#39;t show the rendered HTML of the code of author. It shows the page as a source code.

Is it possible to see it as rendered HTML directly? Otherwise I always need to download the whole ZIP just to see the result.

When I open a **pull request** on [GitHub][1].  
All commits since my last request and all new ones ***are automatically added to this request***.  

I can&#39;t seem to control which commits are added and which are not.  
When I try to open another pull request, I get an &quot;Oops! There&#39;s already a pull request&quot; error.  

Is there any easy way to open multiple pull requests without having to mess around with the command line?

How to open multiple pull requests on GitHub

I&#39;m working with another developer on a project, and we&#39;re using Github as our remote repo. I&#39;m on a Mac using git 1.7.7.3, he&#39;s on Windows using git 1.7.6.

This is what&#39;s happening

 1. One of us (let&#39;s call him developer A, but it doesn&#39;t matter which one) pushes a set of commits to GitHub.
 2. The other (developer B) makes some local commits.
 3. B does a `git pull`.
 4. B does a `git push`.
 5. Looking at the commit history log, I see **Merge branch &#39;master&#39; of github.com:foo/bar**

The commit log gets littered with &quot;Merge branch&quot; messages over time, and also shows developer B as committing changes that developer A made. The only way we&#39;ve found to prevent this issue has been to do a `git pull --rebase` at step 3, but I don&#39;t know what side effects rebasing will introduce. This is my first time working on a multi-developer git repo, so is this just normal behavior? Any thoughts on how to solve this issue?
