How To Scan QR Code on Windows Laptop.

A QR code, or Quick Response code, is a two-dimensional barcode that can store data, such as text or a web link, in a matrix of black squares arranged on a white background. We all usually use our phones to scan any QR Code but it becomes a challenging task when we have to scan QR on our laptop. 

In this guide, we will learn how to scan a QR code on our Windows laptop using our laptop camera and Google Lens. 

Scan QR Code Using Windows Camera App.

We typically use Windows cameras to take photos and videos but now Microsoft has added an additional feature to scan QR codes as well.

Click on the Windows button on the keyboard and search for the "Camera" app in the menu. In the latest update on Windows, they have added a barcode scan button just below the button that we use to take photos.  

If you do not see this feature on a Windows laptop then it might be possible that you are using an older version of Windows 11. 

To enable this feature on older versions, click on the gear icon in the top left corner and open "Related Settings" to enable the toggle button of "Try out new experimental features." Restart the Camera app to get the barcode icon.

Now place your QR code in front of the camera and it will scan it automatically.

Scan the QR Code Using Google Lens.

You can also use the Google image search feature that is available in the Google Chrome browser to scan a QR Code.

In the Chrome browser, right-click on the QR image you want to scan and click on the "search image with Google" option. 

You will see that a Google Lens side is open in our browser itself providing all the details about the QR code. It will show the attached link present inside the QR with a direct link to visit the website. 

These are the two methods by which you can scan QR on any Windows laptop. You can also easily generate a QR code for any page in Chrome browser just by right-clicking and then choosing "Create QR Code for this Page".

How To Find Mac Address on Windows, macOS and Linux.

MAC (Media Access Control) address is a unique identifier assigned to a network interface card (NIC) in a device, providing it with a distinct digital identity on a network. Comprising twelve alphanumeric characters, the MAC address is often expressed as six pairs of two characters separated by colons or hyphens (e.g., 00:1A:2B:3C:4D:5E).

Here we show you the different ways to find the MAC Address of your laptop on various operating systems like Windows macOS and Linux. 

Find the MAC Address on Windows using CMD.

It is easy to find the MAC Address on a Windows laptop using the Command Prompt (CMD). Below are steps you can follow:

1. Press the Windows key + R to open the Run dialog. Type cmd and press Enter to open the Command Prompt.

2. In the Command Prompt window, type the following command and press Enter.

ipconfig /all

3. Look for the network adapter you're interested in; it might be labeled as a "Wireless LAN adapter" for Wi-Fi or an "Ethernet adapter" for wired connections.

4. In the information displayed, find the "Physical Address." This is your MAC address. It usually appears as six pairs of alphanumeric characters separated by hyphens or colons (e.g., 00-1A-2B-3C-4D-5E).

Now you've successfully retrieved the MAC address of your Windows computer using the Command Prompt.

Find MAC Address on macOS.

You can find the MAC Address on a macOS device in the network settings. Below are the steps to follow:

1. Click on the Apple logo in the top-left corner of your screen. Select "System Preferences" from the drop-down menu.

2. In the System Preferences window, locate and click on "Network."

3. Choose the network connection for which you want to find the MAC address (Wi-Fi or Ethernet) from the left sidebar.

4. Once you've selected the network connection, click on the "Advanced" button in the lower-right corner.

5. In the advanced settings, go to the "Hardware" or "Ethernet" tab. Here, you will find the "MAC Address" or "Hardware Address." 

Find the MAC Address on Linux.

To discover the MAC (Media Access Control) address on a Linux system, you can use the command line. Here's a step-by-step guide:

1. Launch the terminal on your Linux system. You can usually find it in your applications menu or use a keyboard shortcut like Ctrl + Alt + T.

2. In the terminal window, type the following command and press Enter.

ip link show

3. Look for the network interface for which you want to find the MAC address. Common interfaces include eth0 for Ethernet and wlan0 for Wi-Fi.

4. In the output, find the line labeled "link/ether" followed by the MAC address. 

Alternatively, you can use the following command specifically for the MAC address.

cat /sys/class/net/<interface>/address

Replace <interface> with the name of your network interface (e.g., eth0 or wlan0).

Frequently Ask Questions.

Q: What is the Use of MAC Address?

Answer: The primary use of a MAC address is in network communication. It serves as a hardware address for devices to interact within a local network, facilitating the delivery of data to the intended recipient. This address is crucial for device recognition, enabling routers and switches to forward data accurately to the designated device. 

Q: What is the difference between a MAC Address and an IP Address?

Answer: A MAC Address is a hardware-level identifier assigned to a device's network interface, while an IP Address is a logical identifier assigned to a device on a network. MAC Addresses operate at the data link layer, and IP Addresses operate at the network layer of the OSI model. While IP addresses handle global communication, MAC addresses manage local network communication, making them essential for the seamless functioning of networked devices. 

Q: Is the MAC Address visible to others on the internet?

Answer: No, the MAC Address is typically not visible beyond the local network. When data leaves the local network and travels through routers, the source MAC Address is replaced with the router's MAC Address.

Q: Why might I need to know my device's MAC Address?

Answer: Knowing your device's MAC Address is useful for network troubleshooting, configuring network settings, implementing security measures such as MAC filtering, and ensuring proper device recognition on a network.

Q: Can two devices have the same MAC Address?

Answer: No, each MAC Address is unique. The probability of two devices having the same MAC Address is extremely low due to the large address space available.

Q: Does the MAC Address change when switching networks?

Answer: No, the MAC Address remains constant for a specific network interface. It only changes if the user manually modifies it or if the device undergoes hardware changes, such as a network card replacement.

How To Enable Auto Format On Save in VS Code?

Whenever we write some code in our Visual Studio Code, we have to spend our precious time formatting the code for better readability and understanding. Any code with poor formatting is hard to understand and debug. Proper positioning of curly brackets and indentation is very important because it helps us to understand which part of the code is ending where.

It is okay to format a few lines of code manually but imagine if we are writing 1000 lines of code and we are spending a lot of our time in formating them correctly. But many Visual Studio Code users don't know about the auto-formatting feature that is available in VS Code.

Step 1: Open your Visual Studio Code and click on the Settings icon from the lower-left corner and then select Settings.

Step 2: Now, inside the User section, select Text Editors and expand this section. You can see a setting option name "Formatting" select that option.

Step 3: Inside Formatting, select the check box with the name "Format On Save" and that's it.

Edit your videos for free using VLC media player.

 

VLC is usually thought of as a media player and a very good one at that. However, there’s more to the software than meets the eye. Did you know you can use it to make simple edits to your videos as well as just watch them? This saves you needing to download a separate video-editing tool if you’re short on space or don’t use one often enough to justify the installation.

 

Trim a video clip using a VLC media player.

 

#Step 1:

First, we’ll look at how to trim video, so you can remove unwanted sections to create a clip. To do this, you need some extra tools. Open the View menu and choose Advanced Controls. This adds a Record button and a useful ‘Frame by frame’ button.

 

#Step 2:

Load the video and watch it through to make sure you’re familiar with where you want to start and endpoints to be. Use the slider to get the video near and immediately press the Record button when you get to the correct place.

 

#Step 3:

You have to mark the end of your clip manually. When the video gets to the stop point, click the Record button again. The trimmed video file is saved to your Videos folder with ‘vlc_record’ at the front of its name. Do this as many times as required to collect the clips that you need.

 

Stick video clips together using a VLC media player.

While VLC is perfectly capable of sticking video clips together, the option was removed from the latest version of the graphical interface. However, the action can still be performed from the Command Prompt. Start by renaming the files you want to stitch together-use a simple, consecutive system, such as numbering them.

 

#Step 1:

Close any instances of VLC that you have open. Enter cmd in the search box to launch the Command Prompt, and navigate to the folder that contains your renamed video files. In our case, we used cd c:\Users\Praveen Kumar\Videos.

 

#Step 2:

Next, type a command with the path to the vlc.exe file, the names of all the files you want to join, and a couple of additional commands including the name of the final file. Our was “C:\Program Files\VideoLAN\VLC\vlc.exe” 1.mp4 2.mp4 --sout “#gather:std{access=file,dst=join.mp4}” --sout-keep

 

#Step 3:

VLC opens and joins the files together. The process is carried out discreetly, so you won’t see anything appear on the screen. You now have to shut VLC down again before the new file (in our case, called ‘join’) is properly finished. If you look at it before closing VLC, it will appear to be an empty file.

 

#Step 4:

The file’s thumbnail appears. You can reopen VLC and play the video as normal. If you want to watch any changes to the file, such as adding more clips, make sure you rename the output file in Step 2, so it doesn’t overwrite your existing file.

 

#Step 5:

You may feel your video is a bit boring and decide to spice it up with a few video effects. If you do this as you record your clips above, you can insert them into your finished product. Click the ‘Show extended settings’ button and click the Video Effects tab.

 

#Step 6:

There are plenty of effects to experiment with, such as changing the color of your video from the Colors tab. Here, we’ve chosen a Sepia tint. The Essential tab has subtler color changes, Geometry lets you rotate the video and Overlay can insert a logo or text.  

How To Apply Dark Mode to all websites in Edge Browser.

The new Chromium Edge browser is packed with useful new features and some of the edge’s features are tucked away below the bonnet which you can enable through Edge flags settings.

One of the interesting features that you can enable from Edge flags settings in dark mode for web content.

I have already explained how to activate Edge’s dark mode, but this just changes the color of the browser’s interface and doesn’t have any effect on the web pages you visit.

To read the web content in dark mode, type edge://flags in the address bar and search for "dark" in the Search Flags box.

Click on the drop-down next to ‘Force Dark Mode for Web Contents’, then change this to Enable and Restart your browser when prompted.

Now your Edge browser is ready to load all web content in dark mode and later if you want you can go through the same settings to disable it. 20 Best Features of Chromium Edge Browser. 

Discard Inactive tabs automatically in Google Chrome.

Auto Tab Discard solves everyone’s biggest moan about Chrome - by automatically ‘killing’ unused tabs, it claws back much-needed memory. This should speed up your browser and save battery life when you’re using a laptop.

Features of Auto Tab Discard.

• It speeds up the browser and minimizes memory usage.
• It designates specific tabs to be whitelisted to prevent discarding.
• You can retain discarded tabs after closing and re-opening your browser.
• The favicon of a website displays the discarded state.

Click the extension’s toolbar button for a range of quick settings that let you swiftly discard the current tab or any other tab you may have open, in any Chrome window.

Your tabs won’t suddenly disappear- instead, the browser tool puts a discarded tab into a suspended state until you click back into it, at which point it will reload. You can also jump between current tabs, close them using the navigation arrows or order all tabs to remain open during your session.

             

However, it’s in the add-on’s settings where the ‘auto’ part of its name occurs. Here, you can set a time limit that kicks in when you have a specific number of tabs open. 

How To Print a List of files in a Folder in Windows 10.

I love watching animation films a lot and to store then I have a 3TB hard drive filled with old animation movies. But managing the list of movies which I’ve already seen becomes difficult. I decided to print the titles of these films so I can track the list before watching the next movie.

After searching for sometimes, I get this old Windows Command Prompt trick to print the list of files name of a folder.

You can save the list of files names of any folder with the help of this Windows Command Prompt trick.

Print a List of files in a folder.

Press Windows+R and enter cmd to open the Command Prompt window. In the window, type: cd c:\users\Probin Kumar\documents and press Enter(Probin Kumar is my system name you have to give your own pc name), it will change the directory to the c: drive. Change the letter or the path if your external drive uses a different letter.

After the first command type: dir> list.txt and press Enter. The second command gathers all the filenames and saves them to a file named list.

The >list.txt part tells the command to direct all output to a file called ‘list.txt’ instead of displaying it on the screen. The file is created if it doesn’t exist or overwritten if it does.

After running these commands, open Explorer and double-click list.txt on the C: drive. This should open it in Notepad.

You can print the list of files from Notepad by pressing Ctrl+P if you want a hard copy but, with the file list in Notepad, you could also use the Find command to search for filenames. Press Ctrl+F to find any text, such as the full or partial name of a file, to see if you already have it.
