In previous article I described how-to Deploy Parsoid on openSUSE 13.1 (which turns out to be quite a challenging task). Parsoid is component required for VisualEditor. Now it’s time for VisualEditor deployment.

Downloading VisualEditor

At the moment, when I’m doing deployment, stable version of MediaWiki is 1.24.2. VisualEditor is an extension written for certain version of MediaWiki, hence we can’t just download latest version and use it. It has to be specific release for specific MediaWiki version.

So, first we download VisualEditor for MediaWiki 1.24.2:

git clone -b REL1_24 https://github.com/wikimedia/mediawiki-extensions-VisualEditor.git
cd mediawiki-extensions-VisualEditor/
git submodule update --init

Once it’s done we need to place content of mediawiki-extensions-VisualEditor in extensions/VisualEditor folder under MediaWiki folder structure.

Finally, once we have all files in proper places it’s time to inform MediaWiki about VisualEditor.

Changes to LocalSettings.php

Changes which have to be applied to LocalSettings.php:

# VISUAL Editor
require_once("$IP/extensions/VisualEditor/VisualEditor.php");
$wgDefaultUserOptions['visualeditor-enable'] = 1;
$wgHiddenPrefs[] = 'visualeditor-enable';
$wgVisualEditorParsoidURL = 'http://localhost:8000';
$wgVisualEditorParsoidPrefix = 'localhost';

From now on you can enjoy VisualEditor until you decide to upgrade to newer version of MediaWiki.
Prior to that I would suggest to check if there is VisualEditor available for new release and test it prior to live deployments.

If you want to replace string in multiple files name you can simply use PowerShell for that.

Dir -Recurse | Rename-Item -NewName { $_.name -replace "file","name-of-file" }

If you need to capture configuration of Windows-based DHCP server for documentation or review purposes, this might be handy:

netsh -r lab-dc-01 dhcp server dump > C:\dhcp-lab-dc-01.txt

NOTE: lab-dc-01 in example command is name of the Windows server which has DHCP installed.

Example DHCP server dump from Windows Server 2008 R2 you can see here. It contains one scope for subnet 172.16.90.0/24, option for DNS and default gateway defined.

Quick steps which should be done as pre-migration steps when you want to migrate System Center Configuration Manager 2007 R2 to System Center 2012 SP1 Configuration Manager.

Diagram below shows schematics of the lab environment prepared for migration testing.

Recently I had issue which occured without any particular reason on SQL Server 2012. All of the sudden I start getting error message:

Cannot connect to WMI provider. You do not have permission or the server is
unreachable.
Note that you can only manage SQL Server 2005 servers with SQL
Server Configuration Manager.
Invalid Namespace.

when tried to run SQL Server Configuration Tools.

What resolved situation is command:

mofcomp C:\Program Files\Microsoft SQL Server\100\Shared\sqlmgmproviderxpsp2up.mof

After upgrading to macOS Mojave you might experience following error when trying to run some command line tools like git, for example:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

To resolve that run those commands in Terminal:

sudo xcode-select --switch /Applications/Xcode.app
sudo xcode-select --switch /Library/Developer/CommandLineTools

Issue should be resolved.

If there is a need to pass specific credentials to Get-WmiObject in order to gather information from remote machine, here is how you can do it:

$LAdmin = "DOMAIN\Administrator"
$LPassword = ConvertTo-SecureString "Password!" -AsPlainText -Force
$Credentials = New-Object -Typename System.Management.Automation.PSCredential -ArgumentList $LAdmin, $LPassword

Once $Credentials object is created you can easily use it to gather information from remote PC:

Get-WmiObject -ComputerName $computername -Class Win32_VideoController -Namespace "root\cimv2" -Credential $Credentials

During the quest about Angeline’s daughter it might be not possible even to find Aldis. It is possible that he died during attack on Solitude. In that case some easiest way is to bring Aldis to player 🙂
