Is Blockchain the Right Technology for My Application?

Helge Klein - Mon, 03/19/2018 - 14:23

This is an attempt at guidelines to help in technology decisions about when and where to use blockchain technology.

Blockchain in a Nutshell

A blockchain is a distributed list more than one entity can add new elements to. Each list element cryptographically validates its predecessor. Combined with the fact that adding new elements is computationally expensive, this protects the list’s integrity.

chain chain chain by lisa cee under CC

Pros and Cons of the Blockchain Architecture

Let’s start with what blockchain is good at:

  • Due to the distributed nature, there is no dependency on any individual entity for the management of the data
  • Tampering with the data is uneconomical because of the huge resources that would be required

And here are the caveats:

  • Maintaining the list is highly inefficient due to the tamper-proof architecture
  • The throughput in transactions per second is very low compared to a database
  • Storage requirements can be high because verification of the list’s integrity requires access to all blocks
When to Use Blockchain Technology

From the above, we can deduce where blockchain is a good technology choice.

Trust and Accountability

Legal contracts allow for pretty efficient management of accountability and – indirectly – trust. Making a system’s technology tamper-proof is not necessary when the risks of tampering are too high for the parties involved.

Takeaway: blockchain technology only makes sense where traditional legal instruments are insufficient or not applicable.

Dependencies on Elements Outside the Blockchain

If you cannot move the entire data set including all dependencies to the blockchain, the mechanisms that protect the blockchain’s integrity are wasted. People will simply cheat elsewhere in the process.

Takeaway: a blockchain must be self-sufficient and not rely on external data.

Processing Speed and Efficiency

Blockchain technology incurs a high computational overhead. Compared to databases, blockchains are inefficient and slow.

Takeaway: blockchains are not replacements for databases.

Summary

Putting the hype aside, there seem to be very few use cases where blockchains would genuinely be the best technology choice. Bitcoin seems like a good fit but is hampered by the low slow transaction speed and huge (energy) inefficiencies.

Download, Install, Import Visual C++ Redistributables with VcRedist

Aaron Parker's stealthpuppy - Fri, 03/16/2018 - 10:10

Last year I wrote a PowerShell script that can download, install or import the Visual C++ Redistributables into MDT or ConfigMgr. Long-term maintenance of the full feature set in a single script is a little unwieldy so I’ve re-written the script and created a PowerShell module – VcRedist.

Refactoring the script into a module has been a great little project for creating my first PowerShell function and publishing it to the PowerShell Gallery.

Why VcRedist?

At this point, I’m sure you’re saying to yourself – “Aaron, haven’t you just created Chocolatey?”. In a way yes, this module does exactly what you can do with Chocolatey – install the Visual C++ Redistributables directly to the local machine. Although you can download and install all of the supported (and unsupported) Redistributables, the primary aim of the module is to provide a fast way to download and import the Redistributables into the Microsoft Deployment Toolkit or System Center Configuration Manager for operating system deployments.

Module

The VcRedist module is published to the PowerShell Gallery, which means that it’s simple to install the module and starting importing with a few lines of PowerShell. For example, here’s how you could install the module, download all of the supported Redistributables and import them into an MDT deployment share:

Install-Module -Name VcRedist Import-Module VcRedist $VcList = Get-VcList | Get-VcRedist -Path "C:\Temp\VcRedist" Import-VcMdtApp -VcList $VcList -Path "C:\Temp\VcRedist" -MdtPath "\\server\share\Reference"

This results in each of the Visual C++ Redistributables imported as a separate application with all necessary properties including Version, silent command line, Uninstall Key and 32-bit or 64-bot operating system support.

Visual C++ Redistributables imported into an MDT share with VcRedist

The same approach can be used to import the Redistributables into a ConfigMgr site:

Install-Module VcRedist Import-Module VcRedist $VcList = Get-VcList | Get-VcRedist -Path "C:\Temp\VcRedist" Import-VcCmApp -VcList $VcList -Path "C:\Temp\VcRedist" -CMPath "\\server\share\VcRedist" -SMSSiteCode LAB

Just like MDT, each Redistributable is imported into ConfigMgr; however, Import-VcCmApp copies the Redistributables to a share for distribution and creates and application with a single deployment for each one.

Visual C++ Redistributables imported into ConfigMgr with VcRedist

Of course, the module can download and install the Redistributables to the local machine:

Install-Module VcRedist Import-Module VcRedist $VcList = Get-VcList | Get-VcRedist -Path "C:\Temp\VcRedist" $VcList | Install-VcList -Path C:\Temp\VcRedist

By default, this installs all of the supported Redistributables:

Visual C++ Redistributables installed locally with VcRedist

Note that the 2015 and 2017 Redistributables are the same version, so the end result will include only the 2017 versions.

Functions

This module includes the following functions:

Get-VcList

This function reads the Visual C++ Redistributables listed in an internal manifest or an external XML file into an array that can be passed to other VcRedist functions. Running Get-VcList will return the supported list of Visual C++ Redistributables. The function can read an external XML file that defines a custom list of Visual C++ Redistributables.

Export-VcXml

Run Export-VcXml to export the internal Visual C++ Redistributables manifest to an external XML file. Use -Path to define the path to the external XML file that the manifest will be saved to. By default Export-VcXml will export only the supported Visual C++ Redistributables.

Get-VcRedist

To download the Visual C++ Redistributables to a local folder, use Get-VcRedist. This will read the array of Visual C++ Redistributables returned from Get-VcList and download each one to a local folder specified in -Path. Visual C++ Redistributables can be filtered for release and processor architecture.

Install-VcRedist

To install the Visual C++ Redistributables on the local machine, use Install-VcRedist. This function again accepts the array of Visual C++ Redistributables passed from Get-VcList and installs the Visual C++ Redistributables downloaded to a local path with Get-VcRedist. Visual C++ Redistributables can be filtered for release and processor architecture.

Import-VcMdtApp

To install the Visual C++ Redistributables as a part of a reference image or for use with a deployment solution based on the Microsoft Deployment Toolkit, Import-VcMdtApp will import each of the Visual C++ Redistributables as a separate application that includes silent command lines, platform support and the UninstallKey for detecting whether the Visual C++ Redistributable is already installed. Visual C++ Redistributables can be filtered for release and processor architecture.

Each Redistributables will be imported into the deployment share with application properties for a successful deployment.

Import-VcCMApp

To install the Visual C++ Redistributables with System Center Configuration Manager, Import-VcCmApp will import each of the Visual C++ Redistributables as a separate application that includes the application and a single deployment type. Visual C++ Redistributables can be filtered for release and processor architecture.

Tested On

Tested on Windows 10 and Windows Server 2016 with PowerShell 5.1. Install-VcRedist and Import-VcMdtApp require Windows and the MDT Workbench. Get-VcList, Export-VcXml and Get-VcRedist do work on PowerShell Core; however, most testing is completed on Windows PowerShell.

To Do

Right now, I have a few tasks for updating the module, including:

  • Additional testing / Pester tests
  • Add -Bundle to Import-VcMdtApp to create an Application Bundle and simplify installing the Redistributables
  • Documentation updates

For full details and further updates, keep an eye on the repository and test out the module via the PowerShell Gallery.
