GUI Merge Tool for Git on Windows

So Git doesn’t come with a GUI based merge tool out of the box, which is fine. It’s rather easy to configure Git to use a visual 3-way diff tool.  Here’s some tips on how to setup a GUI merge tool for Git on Windows.

Which one to choose?

Well, that’s a personal choice. Popular ones for Windows seems to be either kdiff3 or P4V visual client.

Here, I will go through the steps to setup the P4Merge: Visual Merge Tool.

First, download the client from Perforce download page.

Start the setup and select only the “Visual Merge Tool” feature:

Select the Visual Merge Tool feature
Select the Visual Merge Tool feature

After the installation has finished, you will need to configure Git to use it. Open a Git bash and type in these two commands;

git config –global merge.tool p4merge
git config –global mergetool.p4merge.cmd ‘”c:\Program Files\Perforce\p4merge.exe” “$BASE” “$LOCAL” “$REMOTE” “$MERGED”‘

That should do it. You can now do visual merging using:

git mergetool

You can also do visual diffs using:

git difftool


How to really uninstall Java 7 JRE on Mac OS X

Thanks to this stupidity from Oracle, I needed to uninstall Java 7 and go back to the Java v6 runtime.

(Hey, Oracle, this bug was reported 9 months ago.)

Well, the official way of  uninstall Java 7 and roll back to v6 from Oracle and Apple didn’t work for me. $ java -version still reported v1.7.

Thanks to Topher Kessler, this way worked for me;

delete the file 1.7.0.jdk located in /Library/Java/JavaVirtualMachines

Delete the v1.7.0.jdk file to uninstall Java 7
Delete the v1.7.0.jdk file

To call this method, the “Membership.Provider” property must be an instance of “ExtendedMembershipProvider”.

Membership Provider property must be an instance of ExtendedMembershipProvider

Have you just created an ASP.NET MVC 4 internet project, decided to use the universal providers to utilize SQL Azure? So you have installed the NuGet package Microsoft ASP.NET Universal Providers and now your project bombs with:

To call this method, the “Membership.Provider” property must be an instance of “ExtendedMembershipProvider”.

You search for a solution, find Jon Galloway article SimpleMembership, Membership Providers, Universal Providers and the new ASP.NET 4.5 Web Forms and ASP.NET MVC 4 templates , where he states: “If you want to use the new AccountController, you’ll either need to use the SimpleMembershipProvider or another valid ExtendedMembershipProvider. This is pretty straightforward.”

Well, he fails to describe what you’ll need to do if you want continue to use the AccountController. Fear not, here’s what you’ll have do to.

Edit your web.config and replace:

<profile defaultProvider=DefaultProfileProvider>
  <add name=DefaultProfileProvider” type=System.Web.Providers.DefaultProfileProvider, System.Web.Providers, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35
applicationName=/ />
<membership defaultProvider=DefaultMembershipProvider>
    <add name=DefaultMembershipProvider
