How to debug Python code in VS Code with arguments passed from command line

 Debugging Python code in VS Code with arguments passed from the command line is a straightforward process. Here are the steps you can follow: 1. Open the Python file that you want to debug in VS Code. 2. Set breakpoints in the code where you want to pause and inspect variables. 3. Open the Debug panel in VS Code by clicking on the Debug icon in the Activity Bar or by pressing `Ctrl+Shift+D` on Windows or `Cmd+Shift+D` on Mac. 4. Click on the "create a launch.json file" button and select "Python" as the environment. 5. In the launch.json file that opens, modify the "args" attribute to include the command-line arguments you want to pass to the Python script. For example:    ```    "args": ["arg1", "arg2"]    ```    Replace "arg1" and "arg2" with the actual arguments you want to pass. NOTE: Add the below property in the launch.json file.     "purpose" : [ "debug-in-terminal" ] 6. Save the

Go error: go : go.mod file not found in current directory or any parent directory; (working on GOPATH/src)

As of Go 1.16, the   GO111MODULE   environment variable is treated as "on" by default, meaning Go expects to find a   go.mod   file, and no longer falls back to pre-module   GOPATH   behavior. If you want to go back to the pre-1.16 behavior, you now have to explicitly specify  GO111MODULE=auto , but you're far better off creating a  go.mod  file. See  https://golang.org/doc/go1.16#go-command  and  https://golang.org/ref/mod Source - https://stackoverflow.com/questions/67929883/go-error-go-go-mod-file-not-found-in-current-directory-or-any-parent-director

API architectural styles

The following image displays the most common architectural styles for APIs. 🔹 1. REST REST, which was proposed in 2000, is the most widely used style for APIs. It is often utilized between front-end clients and back-end services, and it adheres to six architectural constraints. The payload format may be JSON, XML, HTML, or plain text. 🔹 2. GraphQL Meta proposed GraphQL in 2015. It provides a schema and type system that is ideal for complicated systems where entities' relationships are graph-like. In the diagram below, GraphQL can retrieve user and order information in one call, while REST necessitates multiple calls. GraphQL does not replace REST but can be built upon existing REST services. 🔹 3. Web socket Web socket is a protocol that enables full-duplex communications over TCP. Clients create web sockets to receive real-time updates from back-end services. Unlike REST, which always "pulls" data, web socket allows data to be "pushed". 🔹 4. Webhook Webhook

Difference between Hub Switch Router & Firewall

  Hub Hubs are used to connect multiple devices in a network. They’re less likely to be seen in business or corporate networks than in home networks. Hubs are wired devices and are not as smart as switches or routers. Switches Switches are wired devices that know the addresses of the devices connected to them and route traffic to that port/device rather than retransmitting to all devices. Offering greater efficiency for traffic delivery and improving the overall throughput of data, switches are smarter than hubs but not as smart as routers Router Routers are used to control traffic flow on networks and are often used to connect similar networks and control traffic flow between them. Routers can be wired or wireless and can connect multiple switches. Smarter than hubs and switches, routers determine the most efficient “route” for the traffic to flow across the network. Firewalls Firewalls are essential tools in managing and controlling network traffic and protecting the network. A firew

From UX perspective is it good to show all prerequisite checks in a single screen or split them into multiple screens?

From a UX perspective, it's generally best to split prerequisite checks into multiple screens if they are numerous or complex, especially if they require user input or interaction. When multiple prerequisite checks are displayed on a single screen, it can be overwhelming for the user, and it may be difficult to understand which checks have been completed and which ones are outstanding. This can lead to confusion, frustration, and errors. Splitting the prerequisite checks into multiple screens can make the process more manageable for the user. Each screen can focus on a specific task or set of tasks, with clear instructions and feedback on completion. This can help the user feel more in control of the process and less overwhelmed by the overall number of prerequisite checks. However, if the prerequisite checks are simple and can be completed quickly, it may be appropriate to display them all on a single screen, provided they are clearly organized and easy to understand. In this case

Netflix strategy on preventing password sharing

Netflix has decided to end the practice of password sharing. Previously, they had encouraged sharing passwords with friends and family, but now they require users to confirm that they live in the same household or purchase their own subscription. To confirm that someone outside the household is using the account, the primary account holder will need to verify their device using a 4-digit code. The device will have access for seven days before requiring another verification.  Netflix considers a household as a location where the account owner and others sharing the account live. They will use IP addresses, device IDs, and account activity to confirm if the user belongs to the household. If the account holder is traveling or connected to the home WiFi, they won't need to verify their device, but they need to connect to the home WiFi once every 31 days.  However, if someone outside the household is using the account, they will be asked to verify and failure to do so may result in bein
