cyg-get rsync
cyg-get ncurses

Install a hypervisor (Hyper-V or VirtualBox). Hyper-V on windows is a feature
If you like VirtualBox or need access to USB from guest VMs, use chocolatey to install

Vagrant Usage

A fast and furious howto...

Goto https://app.vagrantup.com/boxes/search? and find the box you are looking for. For example, I am looking for CentOs box built for hyperv
Open a Cygwin terminal in administrative mode
Count to four and you're done. Assuming that you are new kid on the block and haven't customized vagrant file, just type the following commands in the Cygwin terminal...
```
  mkdir centos
  cd !$
  vagrant init centos/7
  vagrant up --provider=hyperv
```
If you are virtualbox fun, just switch hyperv with virtualbox in the --provider argument

Usefull commands

Docker

List containers

docker ps

Stop container

Knowing the name you provided it is easy to stop the container

docker stop <your-container-name>

Follow logs

docker logs --tail 1000 <your-container-name>

Delete images

Delete images sourced from the "thereponame"

&docker images --format "{{.Repository}}:{{.Tag}}" | foreach { $_.split(' ')[0]} | where-object {$_   -Like "thereponame*"} | foreach {docker image rm $_}

Get container IP

Presuming that we have a doduck image with tag dev

From powershell console

 &docker ps --filter "status=running" --filter "ancestor=doduck:dev" --format "{{.Names}}" | foreach {docker inspect --format '{{ .NetworkSettings.Networks.nat.IPAddress }}' $_ } | Select-Object -first 1

From DOS console

FOR /F "tokens=*" %m IN ('docker ps --filter "status=running" --filter "ancestor=doduck:dev" --format "{{.Names}}" ') do (FOR /F "tokens=*" %g IN ('docker inspect --format "{{ .NetworkSettings.Networks.nat.IPAddress }}" %m') do (SET DODUCKIP=%g))
echo %doduckip%

From a DOS batch file

FOR /F "tokens=*" %%m IN ('docker ps --filter "status=running" --filter "ancestor=doduck:dev" --format "{{.Names}}" ') do (FOR /F "tokens=*" %%g IN ('docker inspect --format "{{ .NetworkSettings.Networks.nat.IPAddress }}" %%m') do (SET DODUCKIP=%%g))
echo %doduckip%

Visual studio IDE

Todo or not todo

If you need to remember tasks and their start position in code, place todo marker wherever you need. Visual Studio will recognize them automatically and will place them in the "Task List" (View menu => Task List).

// todo #124. Issue on serializing culture dependent strings

The todo marker is case insensitive. Todo, toDo, todo are valid forms.

Azure

Azure various notes

Switch the resource plan profile

Login-AzureRmAccount
Set-AzureRmAppServicePlan -ResourceGroupName $YourAzureResourceGroup -Name $YourAzureResourcePlan -Tier Free

Configure Postman for MobileAppService

In order to test a mobile app service guarded by an identityprovider, you may use Postman. The following example use facebook as identity provider. Point your browser to https://yourservice.azurewebsites.net//.auth/login/facebook The returned URL if it is URLdecoded contain a token in JSON format

https://yourservice.azurewebsites.net/.auth/login/done#token={"authenticationToken":"####thetokenstring#####","user":{"userId":"sid:#####ausersid#####"}}

Start a GET in Postman with two headers:

ZUMO-API-VERSION with value 2.0.0
X-ZUMO-AUTH with value ####thetokenstring##### copied from the returned URL

Multilingual App Toolkit

A great tool for automatically translate a bunch of res files to many languages. Install it as tool in Visual studio 2017. Create a free subscription on your Azure account, add a translator service, copy the key from keys, add it to your Credential Manager and you are ready to go. Read this

Notes from the field

It works like a charm (PM 1.0.2 / XF 3.0.0.561731). Pay attention when adding a new translation to:

Add translation language from project context menu M.A.P.
Go to xlf file (in Solution Explorer) and change property "Build Action" to "XLIFF Localization File"
Access "Generate machine translations" from the xlf file M.A.P. context menu
Rebuild the project
