Solution:

To fix 0x800f0954 error, please follow one below solutions and retry the installation.

Method 1: Local Group Policy

• Right click on start and click Run then type gpedit.msc and hit enter.
• Navigate to Computer Configuration > Administrative Templates > System.
• Scroll down to find "Specify settings for optional component installation and component repair" and open the settings.

• And select Enabled and also check the checkbox "Download repair content and optional features directly from Windows Updates instead of Windows Server Updates Services (WSUS)".

• Go back to the PowerShell or Command Prompt window and run gpupdate /force
• Finally rerun the Add-WindowsCapability in PowerShell or DISM command again to install the feature.

Method 2: Registry

Change WSUServer registry value to 0 and then run windows capability or DISM to directly download the components from internet. Use the following PowerShell script or use Registry GUI to do the change:

Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" -Value 0

Restart-Service "Windows Update" -ErrorAction SilentlyContinue

Hopefully you have been able to fix the Add-WindowsCapability or DISM command failed 0x800f0954 error that so many of us have been running into.

Cybersecurity Technologies and Projects

Cybersecurity is the activity of defending a business's data or information against online criminals. Attackers are giving up the conventional or outdated techniques of getting data from customers as the world adjusts to the new reality. They are adjusting to new technologies and techniques that can be used to steal data electronically. Cyber attackers try to get into the network and launch an attack, while cyber defenders try to block or stop the attackers from accessing their data. This is a game of cat and mouse in the world of cyber security. But instead of using physical weapons, these conflicts make use of a variety of the greatest cyber security tools. The same tool can be used in both positive and bad ways.

The significance of cybersecurity can be understood through Mimecast's study. According to the research, there has been a 26% increase in ransomware, an 88% increase in email-based spoofing, and a 67% increase in impersonation fraud.

PowerShell - Special Folders (System Folders)

In VBscript, there existed a concept known as Special Folders, for example, My Documents which could be accessed using the Shell. Application object and passing in a constant that applied to a certain folder. This is also possible using PowerShell.

$a = New-Object -ComObject Shell.Application
Get-ChildItem $a.NameSpace(0x21).Self.Path

The prior two lines of code can also be written as follows: 

Get-ChildItem ((New-Object -ComObject Shell.Application).Namespace(0x21).Self.Path)

Below is the list of special folders and its hex number, please do comment on this post if any of them is/are wrong:

Hex Number	Folder Name
0x1	Internet Explorer
0x2	Programs
0x3	Control Panel
0x4	Printers and Faxes
0x5	My Documents
0x6	Favorites
0x7	Startup
0x8	My Recent Documents
0x9	SendTo
0xa	Recycle Bin
0xb	Start Menu
0xd	My Music
0xe	My Videos
0x10	Desktop
0x11	My Computer
0x12	My Network Places
0x13	NetHood
0x14	Fonts
0x15	Templates
0x16	All Users Start Menu
0x17	All Users Programs
0x18	All Users Startup
0x18	All Users Startup
0x19	All Users Desktop
0x1a	Application Data
0x1b	PrintHood
0x1c	Local Settings Application Data
0x20	Local Settings Temporary Internet Files
0x21	Cookies
0x22	Local Settings History
0x23	All Users Application Data
0x24	Windows
0x25	System32
0x26	Program Files
0x27	My Pictures
0x28	User Profile
0x2b	Common Files
0x2e	All Users Templates
0x2f	Administrative Tools
0x31	Network Connections

You can also use the .NET way in PowerShell: 

[System.Environment]::GetFolderPath("<SpecialFolder>")

• Desktop
• Programs
• Personal
• MyDocuments
• Favorites
• Startup
• Recent
• SendTo
• StartMenu
• MyMusic
• DesktopDirectory
• MyComputer
• Templates
• ApplicationData
• LocalApplicationData
• InternetCache
• Cookies
• History
• CommonApplicationData
• System
• ProgramFiles
• MyPictures
• CommonProgramFiles

Between the following are the possible Enumeration values and their associated numeric values, the VBScript version appears to have more alternatives than the .NET version:

•  0  Desktop 
•  2  Programs 
•  5  Personal 
•  6  Favourites 
•  7  Startup 
•  8  Recent 
•  9  SendTo 
•  11 StartMenu 
•  13 MyMusic 
•  16 DesktopDirectory 
•  17 MyComputer 
•  21 Templates 
•  26 ApplicationData 
•  28 LocalApplicationData 
•  32 InternetCache 
•  33 Cookies 
•  34 History

Various types of SQL Databases

Data Engineers work with numerous types of SQL databases. Today, I'd like to give some information about the various categories and their real-world uses.

Types of Databases

Relational Databases (RDBMS):

They excel in structured data management, which makes them an excellent choice for transactional systems such as e-commerce platforms. Examples are SQL Server, MySQL, PostgreSQL, OracleDB.

NoSQL Databases:

They are used in power applications such as social media platforms and IoT systems, and are ideal for managing enormous volumes of unstructured or semi-structured data. Examples are MongoDB, Cassandra, DynamoDB

Columnar Databases:

Columnar databases expertise is in performing analytical queries on massive datasets. They are an essential component of data warehousing for analytics-driven organisations. Examples are Amazon Redshift, Google BigQuery

Graph Databases:

Ideal for complicated relationship scenarios such as social networks, recommendation engines, and fraud detection systems. Examples are Neo4j, Amazon Neptune

Remember that SQL is the foundation of data-driven decision-making, and comprehending these database types offers up a world of data possibilities.
