mongoid update elements within array

mongoid update elements within array

I am using mongoid 3.1 with Ruby 1.9.3 and I am trying to update a value
within an array. I can successfully perform the following command in
mongodb's CLI, but can't seem to find the appropriate solution/translation
for mongoid.
user.update( { activities: { $elemMatch: { uuid: "1111111-xxxx-xxxx" }}},
{ $set: { 'activities.$.submitted': true }})
For context the document looks like:
{
"_id" : ....,
"user_name" : "bob",
"activities: [
{
uuid: "1111111-xxxx-xxxx",
submitted: true,
},
{
uuid: "222222-xxxx-xxxx",
submitted: false,
},
{
uuid: "333333-xxxx-xxxx",
submitted: false,
}
]
}
The goal is to change submitted to true based on the uuid value. From what
I can tell, all of the "updating" solutions in mongoid only deal with the
attributes at the root of the document and can't have options for the $
positional operator.
Any help would be appreciated.
Thank you

Why do some assembly references have a version and others not when added through NuGet

Why do some assembly references have a version and others not when added
through NuGet

I'm adding all packages through NuGet, so I'm not manually tweaking the
Specific Version property in Visual Studio. However depending on which
package (or even which version) I add, I end up with different ways of how
the reference is added. As you can see below:
A reference to Autofac is added without a version.
A reference to AutoMapper is added, but the assembly version is added as
well. Version=3.0.0.0, Culture=neutral, processorArchitecture=MSIL"
Even stranger is the fact that the stable NuGet package of AutoMapper
doesn't add the version either (make sure you save the csproj file between
changing packages). What's the reason that packages added through the same
method (NuGet install package) results in different configurations?
<Reference Include="Autofac">
<HintPath>..\packages\Autofac.3.1.1\lib\portable-win+net40+sl50+wp8\Autofac.dll</HintPath>
</Reference>
<Reference Include="AutoMapper, Version=3.0.0.0, Culture=neutral,
processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>..\packages\AutoMapper.3.0.0-ci1043\lib\windows8\AutoMapper.dll</HintPath>
</Reference>

Changed Discovery Behavior of Alternative MinGW in Eclipse-CDT(8.2) Bundled in Kepler-version(4.3)

Changed Discovery Behavior of Alternative MinGW in Eclipse-CDT(8.2)
Bundled in Kepler-version(4.3)

When using an alternative MinGW version like e.g.,
mingwbuilds-gcc/g++-4.8.1, the CDT(8.2) bundled in the latest
Kepler-version(4.3) is not able to discover it as a MinGW tool chain. This
behavior is introduced with this latest release.
The MinGW discovery process works fine on such an alternative MinGW in
previous releases like Juno-SR2 bundled with CDT(8.1.1) and so on.
Indeed, there's a workaround to this problem by simply adding a file entry
named mingw32-gcc.exe in MinGW bin directory (e.g., by issuing touch
c:\MinGW\bin\mingw32-gcc.exe)

I've tried to find some documentation of the CDT tool chain discovery
process, especially for this latest CDT 8.2-version, without any success.
So, my question is: Where to find such documentation - if any?
Or, can anybody explain?

Many thanks in advance!

SharedPreferences ListPreference NullPointerException

SharedPreferences ListPreference NullPointerException

I'm trying to set up a list of frequencies in my preferences xml but I
keep getting this error. I have attached all the related files too. I
believe that I set up the values correctly but I can't find where my error
currently is. Also, when I use the SharedPreferences.getString(key,
defaultValue) what value is returned? The ENTRY or the ENTRYVALUE?
