I'm building a website for the first time with Jekyll and I've been following the step-by-step tutorial laid out in the Jekyll documentation. I've created the posts, layout and post list (blog.html) as outlined in step 8, but when I run jekyll serve in my command line my posts are not listed at blog.html. What could be the reason for this?
Here is my _config.yml file (using the default configuration laid out in the doc):

I'm trying to automate some code-related routines in VisualStudio 2017 using integrated Powershell console and VS Automation model (DTE). When I'm working on Solution/Project/File level, things are ok, e.g.
PS> $dte.ActiveDocument.ProjectItem
IsDirty : False
FileCount : 1
Name : FeaturesComposition.cs
Collection : System.__ComObject
Properties : System.__ComObject
DTE : System.__ComObject
Kind : {6BB5F8EE-4483-11D3-8BCF-00C04F8EC28C}
ProjectItems : System.__ComObject
Object : System.__ComObject
ExtenderNames : {}
ExtenderCATID : {610D4615-D0D5-11D2-8599-006097C68E81}
Saved : True
ConfigurationManager :
FileCodeModel : System.__ComObject
Document : System.__ComObject
SubProject :
ContainingProject : System.__ComObject
But when I come to the code model of some particular file, there is nothing to work with:
PS> $dte.ActiveDocument.ProjectItem.FileCodeModel | Format-List -Property *
System.__ComObject
PS> $dte.ActiveDocument.ProjectItem.FileCodeModel | gm
PS>
Is it possible to get access to such submodels? Is there any easy way of dispatching EnvDTE.DTE interface to the existing $dte instance? I've tried some ideas below, but without no success.
Add-Type -Path "$env:VSAPPIDDIR\PublicAssemblies\envdte.dll"
PS> # Explicit cast doesn't work
PS> [EnvDTE.DTE]$dte
[ERROR] Cannot convert the "System.__ComObject" value of type "System.__ComObject#{04a72314-32e9-48e2-9b87-a63603454f3e}" to type "EnvDTE.DTE".
PS> # Wrapper works but it's useless
PS> $wrapped = [Runtime.InteropServices.Marshal]::CreateWrapperOfType($dte, [EnvDTE.DTEClass])
PS> $wrapped.ActiveDocument.ProjectItem.FileCodeModel
System.__ComObject
PS> # GetComInterfaceForObject gives the same IntPtr as IUnknown:QueryInterface
PS> # different from the call to GetComInterfaceForObject for example,
PS> # so I hoped to get another casting results. But it is the same.
PS> $contract = [Runtime.InteropServices.Marshal]::GetComInterfaceForObject($dte, [EnvDTE.DTE])
PS> [EnvDTE.DTE][Runtime.InteropServices.Marshal]::GetObjectForIUnknown($contract)
[ERROR] Cannot convert the "System.__ComObject" value of type "System.__ComObject#{04a72314-32e9-48e2-9b87-a63603454f3e}" to type "EnvDTE.DTE".
Try this:
$fileCodeModel = Get-Interface $dte.ActiveDocument.ProjectItem.FileCodeModel ([ENVDTE80.FileCodeModel2])
I'm trying to create a visulaization of the HDFS block distribution of a cluster.
I plan to create this using Tableau but was wondering what type of visualizations would be able to give you an idea of what nodes need re-balancing, and also an efficient way to get the server log data into tableau?
Before investing too much time in this, you might want to take a look at Twitter's open source HDFS-DU project. This provides a view of utilization based on paths within the file system rather than DataNodes within the cluster, but perhaps that's still helpful for your requirements.
If the goal is just to identify nodes in need of rebalancing, then this information is already accessible on the NameNode web UI "Datanodes" tab. You could also run hdfs dfsadmin -report to get utilization stats for each node in a script.
If none of the above meets your requirements, and you need to proceed with integrating the information into an external reporting tool like Tableau, then a helpful integration point might be the JMX metrics exposed via HTTP on the NameNode. See below for an example curl command that queries some of this information from the NameNode. Note in particular the LiveNodes section, which contains capacity information about each DataNode.
Some additional information about these metrics is available in the Apache Hadoop Metrics documentation.

just tried to get the basic basics up and running and getting some fancy error conditions - most probably some basic steps are screwed up but I don't see the point - so some hints are highly appreciated.
So whats the setup?
VS2010
MVC3 or MVC4 Project - no strings attached, just the templates
Create a really simple Model-Class Team like shown on http://blog.stevensanderson.com/2011/01/13/scaffold-your-aspnet-mvc-3-project-with-the-mvcscaffolding-package/
What happens?
Try (after installing MvcScaffolding through NuGet Console) to call:
Scaffold Controller Team
And get the following error:
PM> Scaffold Controller Team
Scaffolding TeamsController...
Invoke-Scaffolder : The term 'Get-ProjectType' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try again.

uage $CodeLanguage -BlockUi
+ CategoryInfo : NotSpecified: (:) [Invoke-Scaffolder], CommandNotFoundException
+ FullyQualifiedErrorId : T4Scaffolding.Cmdlets.InvokeScaffolderCmdlet
Fancy thing: of course Get-ProjectType itself seems to work (see below), so I'm kind of stuck right now - as this looks like a powershell issue somehow but the cmdlet itself works at least if called directly but not when inside the script? Any hints would be greatly appreciated!
Thanks a lot.

I'm learning PowerShell 2.0 on Windows 7.
My task is simple: I want to listen for a WMI event and then display some information about it.
Here is what I'm currently doing:
Register-WmiEvent -class win32_ProcessStartTrace -sourceIdentifier processStart
Wait-Event
It seems to work. Indeed, I get this when I start a process:
ComputerName :
RunspaceId : bb0f38b9-2f2e-4f7c-98ec-ec3811e8e601
EventIdentifier : 11
Sender : System.Management.ManagementEventWatcher
SourceEventArgs : System.Management.EventArrivedEventArgs
SourceArgs : {System.Management.ManagementEventWatcher, System.Management.EventArrivedEventArgs}
SourceIdentifier : processStart
TimeGenerated : 26/09/2009 15:19:25
MessageData :
Problem is, I don't know how to get detailed information about the event. For example, how do I get the name of the process that just started? Ideally, I would have something like this:
__GENUS : 2
__CLASS : Win32_ProcessStartTrace
__SUPERCLASS : Win32_ProcessTrace
__DYNASTY : __SystemClass
__RELPATH :
__PROPERTY_COUNT : 7
__DERIVATION : {Win32_ProcessTrace, Win32_SystemTrace, __ExtrinsicEvent, __Event...}
__SERVER :
__NAMESPACE :
__PATH :
ParentProcessID : 1480
ProcessID : 6860
ProcessName : notepad++.exe
SECURITY_DESCRIPTOR :
SessionID : 1
Sid : {1, 5, 0, 0...}
TIME_CREATED : 128984449371986347
I can get the above information when I do
(get-event).sender.waitfornextevent()
But, obviously, that's not really what I had in mind - I don't want to wait for another event, I want info on the current one.
Take a gander here:
