pslist not working – solved

I’m a huge fan of Sysinternals tools, and one of my favorites – pslist – suddenly stopped working one day after a reboot. The error message I received was:

Processor performance object not found on PC01
Try running Exctrlst from microsoft.com to repair the performance counters.

The Exctrlst in question is from the Windows Resource Kit. After installing and running the Exctrlst utility, it still didn’t work. Luckily, more Googling led me to running this command:

lodctr /r

Which of course didn’t work either. First I got an error code 5, which I recognized as the old “Access denied” error code, so I ran it again as Administrator. No dice. That just gave me an error code 2.
More Googling until I found the following solution:

C:\> cd C:\Windows\SysWOW64
C:\Windows\SysWOW64> lodctr /r
Info: Successfully rebuilt performance counter setting from system backup store

Yay! And finally:

C:\Windows\SysWOW64> winmgmt.exe /RESYNCPERF
C:\Windows\SysWOW64>

A subsequence pslist worked perfectly.

Bootstrap horizontal scrollbar mystery solved

Sometimes when creating a Bootstrap-based site, I've had a pesky problem with a horizontal scrollbar that appears and just won't go away. It turns out the root cause -- and the solution – are simple.
Essentially, make sure any “row” div is inside a “container” div, e.g.:

Wrong

<div class="row">
    <div class=”col-md-12”>This is some content inside the column</div>
</div>

Right

<div class=”container”>
    <div class="row">
        <div class=”col-md-12”>This is some content inside the column</div>
    </div>
</div>

How StackOverflow does caching

StackOverflow went down for a few hours earlier today, so I was able to read up on how they do caching here: http://meta.stackexchange.com/questions/69164/does-stack-exchange-use-caching-and-if-so-how

Git TFS with Git 2.5 and above - Solved!

I experienced the same issues as the OP here: https://github.com/git-tfs/git-tfs/issues/845

In my case:

$ git tfs clone https://me.visualstudio.com/DefaultCollection/_versionControl $/MyProject
TFS repository can not be root and must start with "$/".
You may be able to resolve this problem.
- Try using $/C:/Program Files/Git/MyProject

The solution, courtesy of dscho: an msys2 flag that looks like the most bastardized bash syntax in the world, but apparently works. (Is this valid bash or a special msys2 thing?)

$ MSYS_NO_PATHCONV=1 git tfs clone https://me.visualstudio.com/DefaultCollection/ $/MyProject
Initialized empty Git repository in C:/Projects/MyProject/.git/

This is documented in the release notes here: https://github.com/git-for-windows/build-extra/blob/master/installer/ReleaseNotes.md#known-issues

EDIT:

You can also double up the initial quote after the $, e.g.:

$ git tfs clone https://me.visualstudio.com/DefaultCollection/ $//MyProject
Initialized empty Git repository in C:/Projects/MyProject/.git/
