The new thing from Mozilla is not a browser, it is a VPN!

Besides Firefox, Mozilla offers now Firefox Relay, an app helping you to mask your email and phone number, and a new Mozilla VPN.

Mozilla has recently announced a new subscription model that will let you use all products together for $6.99 per month. Although this is a little more expensive than the competition that goes around for $5 per month note that with this subscription you are having access to all services, not just VPN.

VPN will not only hide your IP address but will also make sure websites cannot access your real location and it encrypts all of your network activity. Relay will give you protection against spam, serving as a shield for your email and limiting spammers from access to your real email address and phone number. With Mozilla subscription will let you use both services.

Visual studio code is a code editor available for Windows, Linux, and macOS. It is a completely free tool offering you to code in any language without the need to switch to another editor. Visual Studio Code is part of Microsoft Visual Studio which is a complete integrated development environment (IDE). Take notice that Visual studio itself has more advanced tools for developing and testing, it has 24/7 support, training, and Azure for WEB apps. Visual Studio Code is an editor lacking in some advanced features Visual Studio offers.

Visual Studio code Price and royalty

As mentioned Visual Studio code is completely free licensed under the MIT license agreement giving you the tool free to use and sell your product. How it supports Linux, Windows, and macOS, all you need it to go to its official page https://code.visualstudio.com/, download it and start using it. How this is free project backside is that there is no official support, you will have to rely on various articles and community in order to get needed information or problem solution.

Features

Syntax highlighting has become standard and norm for any editor but besides this function VS code offers us also IntelliSense option which goes a step further with code completion, code hinting, and parameter info. This means that VS code is aware of many things going on inside your code and will offer you as you type a menu with options for autocomplete along with variables referenced, function names, etc. VS code offers extensions inside its extensions marketplace where you can add extensions in order to implement new languages, add debuggers, change the layout, etc. This is one of the great features it allows you to easily switch from one project to another, one language to another not leaving your code editor. Working with version control systems like Git is easy with VS Code. You’ll be able to stage files and make commits, then push and pull changes to your remote code repository of choice, right from the editor.

Conclusion about Visual Studio code

Visual Studio Code is one of if not the most flexible and extensible code editors currently on the market that I have ever tried and used. IT has become my code editor of choice simply for reasons that there is really not much it cannot do and it is constantly updated and taken care of. You can really tune it to look and feels how you want with extensions and you really cannot beat the free price tag. I would highly recommend this editor for daily use especially since its biggest competitors like Atom and sublime text have not seen many updates lately.

There are times when you try to open a file, an executable file for instance, but were unable to do so since you encounter an error in an Open File – Security Warning dialog box that says, “This publisher has been blocked from running software on your machine, You must unblock this publisher to run this software”. This kind of error is most likely thrown by your operating system because it considers the file to be unsafe and could potentially harm your computer. However, if you’re certain that the file is harmless, read on as this post will walk you through fixing the error so you can open the file without getting an error. There are various options you can check out to fix the error. You may run the program using Command Prompt or unblock it using File Properties. You could also try turning off SmartScreen or use the unblock file command in Windows PowerShell.

Option 1 – Try running the program via Command Prompt

• Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and hit Enter to open Command Prompt.
• Next, tap the Shift key and right-click on the program or the executable file, and then select the “Copy as path” option.
• After that, paste this path in the Command Prompt window and tap Enter to open the program.

Option 2 – Try to unblock the file using File Properties

• Right-click on the file you were trying to open and select Properties.
• Next, click the Unblock button and then click on the Apply and OK buttons.
• You should now be able to open or access the file without getting the error.

Option 3 – Turn off SmartScreen

The next thing you can do is to turn off SmartScreen temporarily. All you have to do is open the Windows Defender Security Center and from there, go to the App & browser control section. After that, click on the radio button for Off under Check apps and files. Once you’re done, try opening the file again. Don’t forget to enable the SmartScreen back on.

Option 4 – Try to use the Unblock-File command in PowerShell

You might also want to utilize the Unblock-File command in Windows PowerShell as it will unblock the file so you can open it. To execute this command, follow these steps:

• Tap the Win + X keys and then click on Windows PowerShell.
• After opening PowerShell, type or copy and paste this command and tap Enter to execute it: Get-ChildItem -Path 'C:Users<username>Downloads' | Unblock-File
• The command you entered will unblock all the files in the Downloads folder, assuming that’s where the file you were trying to open is stored. If it’s not, then replace the path with the path where the file is located. Take note to also replace “<username>” with your Username.
• Now check if the file has been unblocked by accessing or opening it.

In case you don’t know, Windows now comes with an all-new Light Mode theme which gives a light accent color to the Taskbar, Start, and Notification Area. Aside from that, it also brings new improvements and features. This new theme is somewhere between dark and completely white and in this post, you will be guided on how you can enable this new feature in your Windows 10 computer. Although the Light Mode sure looks stunning and a lot of users love it, it actually switches all the apps plus the Taskbar and Start Menu to the light mode which was not the case before. In addition, the icons in the system tray area, as well as the notification center, are also inverted. To resolve that, there are several ways you can customize the light mode theme as well as activate it in the Windows 10 v1903. How? Refer to each one of the options given below.

Option 1 – Via Theme settings

Windows 10 brought a new theme called “Windows (Light)” which will enable the light mode automatically and will set the accent colors to automatic. This will also apply the new Windows 10 wallpaper on your desktop. To enable Windows (Light), all you have to do is right-click on the desktop and select Themes from the left menu. After that, select the Windows (Light) option under the Change Themes section. This will apply to the Windows (Light) mode.

Option 2 – Via Color settings

The second and more customizable way to activate the light mode is via Settings. Aside from the Light and Dark, Windows also introduced a Custom color option which allows you to decide the default Windows and App mode independently. To enable Light mode via Settings, refer to the steps below.

• First, open Settings and go to Personalization.
• After that, select “Colours” from the left menu.
• Next, select Light under the “Choose your color” section to activate the light mode in Windows 10. This will activate light mode all over your computer.

Note: If after activating light mode, you find that you don’t like it and you want to keep things as they were before (Light App Mode and Dark Windows Mode), you can achieve that using the Custom option. All you have to do is select Custom from the drop-down menu to decide the default Windows and app mode independently. After that, select light under the default app mode and dark under the default Windows mode so that you can keep things as they were before the update. On the other hand, you can also try the opposite version of the light Windows mode and Dark app mode since Windows increased the level of customizability which allows users to use an option of a completely light mode.

The Boot Configuration Data or BCD files have the instructions required by the Windows operating system in order to properly boot the computer. So if you experience any trouble when you boot your computer, then it is possible that it is due to some misconfiguration or even corrupted Boot Configuration Data files. And if you also encounter an error saying,

“The boot configuration data store could not be opened”

while you try to carry out any command on the bcedit.exe, then you’ve come to the right place as this post will guide you on how you can fix this error in Windows 10. This kind of error could pop up if the system is not able to locate the specified file. It is also possible that the requested system device can’t be found or that the boot configuration data store could not be opened. In addition, when you open the System Configuration or MSConfig, you might notice that there is no Boot data, and according to the reports, is that when you try to dual boot the computer, the installer will replace the default bootloader.

Explanation

In case you don’t know, Windows’ earlier versions were stored in the “Boot.ini” file. You can find the entry in the EFI firmware boot manager of the EFI-based operating system which is located at EFIMicrosoftBootBootmgfw.efi. Whatever the cause of the error is, there are several suggestions you can check out to resolve the problem. You can try to set an entry option value in BCD or enable the Advanced options menu, as well as rebuild the BCD. Before you proceed with the troubleshooting options provided below, make sure that you boot your computer into the Advanced Recovery Mode first since that’s where you can find Command Prompt under the Advanced Options. In addition, you also have to suspend or disable BitLocker and Secure Boot on your PC.

Option 1 – Try to set an entry option value in BCD

• Once you’re in the Advanced Options, select Command Prompt.
• Next, execute this command to set an entry point: bcdedit /set {current} Description "TheNameYouWant"
• After the command has been executed, it will enable the system to trust a version of Windows that is not trusted by default. This should fix the problem, if not, follow the next given options below.

Option 2 – Try to specify the BCD file

• In the elevated Command Prompt, execute this command: bcdedit /store c:BootBCD
• Once done, the command will give you a list of options and then execute this next command: bcdedit /store c:BootBCD /set bootmenupolicy legacy
• After that, restart your computer and select your Windows and then tap the F8 key right away.

Note: When you select the legacy option, the Advanced Options menu will be available during the computer boot up and then you can select into which operating system you can boot your computer into.

Option 3 – Try to rebuild the BCD files

The first thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /ScanOS
  • bootrec /RebuildBcd
• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed error code 0xc000014c.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.

If your Windows PC encounters an error, it will display a Blue Screen of Death or BSOD error which usually comes up for a fraction of second and creates some logs or Dumps Files as what other user prefers to call it and then boots your PC suddenly. This process usually takes place quickly that most users find it hard to get the error code and won’t probably be able to check what really went wrong with their PCs. This is where the dump files come in. They are stored internally in your computer and can only be accessed by an administrator. They are classified into 4 main types and in Windows 10 they are either:

1. Complete Memory Dump
2. Kernel Memory Dump
3. Small Memory Dump (256 KB)
4. Active Memory Dumps

Dump Files are useful as they could help you in resolving the problem and so you need to configure your Windows 10 PC to create them but first, you need to make a system restore point. This is essential as you are about to modify some system files as well as critical Windows 10 settings. There are two ways you can create Dump files – first is by modifying the settings in the Startup and Recovery and lastly is via the WMIC command line. Refer to the instructions prepared below to be guided on how you can create Dump files after any BSOD error using these options.

Option 1 – via Startup and Recovery

• Type in “control panel” in the Cortana Search box and then click on Control Panel from the search results to open it.
• After opening Control Panel, you need to make sure that you view the contents by their Category then click on the header link which is labeled “System and Security” or you could also right-click on the This PC icon and then click on Properties.
• Next, select the Advanced system settings from the left panel. Once you do, a new and small window will pop up.
• Under the newly opened window, look for the section called Startup and Recovery and then click on the Settings button.
• And from the System Failure section, you can choose any option from the drop-down for Write debugging information such as:
  • None – this means that there is no dump file created by Windows
  • Small Memory Dump – this means that Windows will create a Minidump file on BSOD
  • Complete Memory Dump – this means that Windows will create a Complete Memory Dump file on BSOD
  • Automatic Memory Dump – this means that Windows will create an Automatic Memory Dump file on BSOD
  • Active Memory Dump – this means that Windows will create an Active Memory Dump file on BSOD

Note: The complete dump needs a page file that is allowed to be the size of the physical memory installed in your PC with a dedicated 1 MB of space for just the page header.

• Now once you have selected the most suitable option for you, just click on OK/Apply and then exit.
• Restart your PC to successfully apply the changes made.

Option 2 – via the WMIC command line

• The first thing you need to do to create Dump files via the WMIC command line is to tap the Win + X keys combination or simply right-click on the Start button and then select the Command Prompt (Admin) option. You could also type in “cmd” in the Cortana search box and then right-click on Command Prompt from the results and select Run as administrator.
• After that, type in any of the commands given below depending on your preferences so that your Windows 10 PC will be configured to create Dump Files:
  • No dump file: wmic RECOVEROS set DebugInfoType = 0
  • Small Memory Dump: wmic RECOVEROS set DebugInfoType = 3
  • Kernel Memory Dump: wmic RECOVEROS set DebugInfoType = 2
  • Complete Memory Dump: wmic RECOVEROS set DebugInfoType = 1
  • Automatic Memory Dump: wmic RECOVEROS set DebugInfoType = 7
  • Active Memory Dump: wmic RECOVEROS set DebugInfoType = 1

Note: A complete dump has to have a Page file which is allowed to be the size of the physical memory installed on your PC accompanied by a 1 MB space for just the page header.

• Now type in “exit” in the Command Prompt to exit it.
• Restart your PC to apply the changes made successfully.
