** Adding a Guest Account in Windows 11 Made Easy with 4 Effective Methods!
Adding a guest account in Windows 11 is a convenient way to allow others to use your computer without compromising your personal files or settings. This feature provides restricted access, allowing guests to browse, use applications, and access the internet without making any system changes.
Microsoft offers four methods to create a guest account in Windows 11:
1. Using the Settings app
2. Command Prompt (with administrator privileges)
3. PowerShell (available in Pro, Enterprise, and Education editions)
4. Local Users and Groups tool (also available in Pro, Enterprise, and Education editions)
Each method provides varying levels of customization and control over user permissions. The guest account has more restricted permissions compared to a standard account, ensuring that guests cannot install or uninstall applications.
To add a guest account, users can choose the method that best suits their needs. For those who prefer using the Command Prompt or PowerShell, these methods provide fast and efficient ways to set up a guest account. Additionally, the Local Users and Groups tool offers advanced features for creating and managing user accounts, including guest accounts.

**Effective Communication in Slack: Tips for Tech Teams**
As teams continue to rely on messaging apps like Slack for collaboration, it's essential to adopt best practices that foster productivity and efficiency. According to a recent article, here are eight valuable tips for tech teams to consider:
1. Avoid unnecessary messages by providing context and questions directly.
2. Use team channels instead of direct messages (DMs) for updates and discussions.
3. Schedule messages to be sent during working hours when the recipient is likely available.
4. Prioritize clear and concise communication, including putting main ideas at the start of messages.
5. Reply promptly to messages, even with a simple "Got it" or thumbs-up emoji.
6. Use Slack reminders if you need to follow up on a message later.
7. Handle Personally Identifiable Information (PII) with care by not posting sensitive info in public channels.
8. Use a TL;DR summary for long messages or meeting notes.
By implementing these tips, tech teams can improve their communication and collaboration within Slack, leading to increased productivity and efficiency.

Open-source developers have created a web application that allows for the development and testing of Ollama AI models, with features such as Retrieval Augmented Generation (RAG) widget for storing and retrieving embeddings. The app also provides a playground for interacting with MySQL and PostgreSQL databases hosted on services like Timescale and Neon.tech, including connection pooling support. A custom API interaction allows users to save query results as a local file or upload to IPFS via Pinata.
** Understanding Software Quality Assurance: The Intersection of Functional and Non-Functional Testing
As software development continues to evolve, ensuring the quality of a product is paramount. Two essential components in achieving this goal are functional and non-functional testing. These twin pillars of software quality assurance (SQA) serve different purposes and focus on various aspects of the product.
**Functional testing** validates a software system against its functional requirements and specifications, ensuring each feature works as expected. This type of testing checks the user interface, APIs, databases, security, client-server applications, and functionality of the application under test.
On the other hand, **non-functional testing** assesses aspects unrelated to specific functions, such as performance, scalability, security, compatibility, and usability. It verifies how well a system responds to requests, handles simultaneous users, behaves under stress, and interacts with other systems and platforms.
Both functional and non-functional testing are critical in the software development lifecycle (SDLC), offering unique value in delivering high-quality software products. By understanding and implementing both types of testing effectively, developers can achieve software excellence and meet user expectations.
