Microsoft will soon offer 4 CPU computer specifically aimed at developers and its name is Volterra. The machine as stated will come with 4 processors but the strange thing is that they will be ARM-based instead of x86.

CEO of Microsoft, mister Satya Nadella has introduced the product and Microsoft has released a youtube video promoting it.

https://youtu.be/yICVNta8jMU

The computer system will have Qualcomm's NPU or built-in neural processing unit to use AI's power to help developers write and produce better and faster code. The sad news is that besides processors used there is no other information on other components that will go into this system.

As seen in the video, the computer reminds me a lot of the apple MAC mini with its size and design, and as stated it is made from recycled plastic which in our opinion will bring the price under $1000.

Microsoft has not provided an official price tag for Volterra, but our hope is that it will be more affordable than building your own development PC. Also, there was nothing said about computer availability, we suspect that the selling model will be typical Microsoft one with first models available only in the USA and moving forward slowly opening it to other markets.

Volterra specifications

As previously said nothing except the number of CPUs and their type has been officially said but we managed to get some information about some other specific things not including its inside components.

The unit will have a fan inside of it for cooling purposes and better performance and that is what was officially stated by Microsoft. On the outside, it is known that the computer will have three USB-A ports, a mini DisplayPort, and an ethernet input. All of these will be positioned on the back of the device, on its left side there will be two USB-C ports.

The unit itself will be running on Windows 11 but it was not disclosed anything about the version, we presume since this is a model aimed for professional use that it will come with Windows 11 PRO version.

Currently available tools for ARM

Since this product is aimed at developers logically support for developing software is a must-have and at the time of this writing software that will come and that will run on Volterra is:

• Visual Studio 2022
• Visual Studio Code
• Visual C++
• Modern .NET 6 & JAVA
• Classic .NET
• Windows Terminal
• Windows Subsystem for Android
• Windows Subsystem for Linux

Conclusion

Once MAC studio has been released it showed that specific builds have their audience and can be sold for less of a price than full-fledged custom-made workstations. There is no doubt that Microsoft Volterra will find its audience but will that be enough to have more versions of this compact computer only time will tell.

Virtual Reality is slowly becoming standard in gaming. More and more affordable headsets are coming out lowering entry prices and making them affordable for all. But in a sea of new VR headsets, it is important to at least purchase a decent one that will perform nicely and hopefully last longer. Therefore in today’s article, we will address some of the best options currently available on the market,

Oculus Quest 2

With its Rift model, Oculus set itself as a big player in VR. Now the company is slowly bowing out of the dedicated, tethered VR headset with its latest Quest 2 designed to primarily be a standalone headset. In case you do not know, tethered headset means that the headset itself is connected to your PC and is using its power to drive your VR experience. Now technical specifications of Quest 2 are pretty OK and it can drive stuff pretty decently and if you want you can purchase the dedicated cable to connect it to your PC for the full experience of games requiring more capable hardware. Oculus Quest 2 is the cheapest headset on this list and with its stable performance, is highly recommended.

Valve Index VR

Although the headset itself is nothing revolutionary or special its controllers are. They can track individual finger movements, making games (that take advantage of them) much more immersive than the standard trigger grips on other controllers. The Index's higher refresh rate makes for smoother action, as well, which is another nice bonus. If you already have an HTC Vive or Vive Cosmos Elite, and their base stations (not the regular Cosmos), you can buy only the controllers.

Sony PlayStation VR

The PlayStation VR is compelling thanks to Sony backing its development, plus the PlayStation 4's affordability and availability compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles). Not really the best of the bunch but still one of the top ones for console gaming. Sony is working on a new PlayStation VR system for the PlayStation 5, with redesigned controllers. The new headset hasn't been revealed yet, but the company has released a preview of the new controllers.

HP Reverb G2 VR

HP headset is one which you get if you want the best image quality in VR headset, sadly controllers did not follow the same quality of headset itself. But this is still a pretty decent headset overall and worth the purchase.

HTC Vive Cosmos

HTC's Vive Cosmos is the upgraded version of the Vive. It features a higher resolution and replaces the external base stations with outward-facing cameras for motion tracking. It's a comprehensive package for whole-room VR. HTC recently released the Vive Pro 2, a high-end VR headset targeting both enterprise users and consumers. This new headset features a 2,448-by-2,448 resolution display for each eye, making it the highest-resolution headset currently available. It's also more expensive than the Cosmos Elite. Sadly one thing that is bringing this headset down is the price.

If you are browsing the internet using the Google Chrome browser in your Windows 10 computer but you suddenly encounter an error message that states, “ERR_ICAN_NAME_COLLISION”, read on as this post will walk you through in fixing the problem. Here’s the full content of the error message:

“The site can’t be reached, This site on the company, organization, or school intranet has the same URL as an external website. Try contacting your system administrator. ERR ICAN NAME COLLISION.”

This kind of error is caused by an error in a private namespace or a random redirection to an incorrect proxy server. There are several ways to fix this error. You can try to check the integrity of the Hosts file or check the proxy. You could also try to use the Registry Editor and apply some tweaks or remove any conflicting browser extensions or flush the DNS cache, as well as run a malware scan.

Option 1 – Try to check the integrity of the Hosts file

To check the integrity of the Hosts file, refer to the following steps:

• You have to navigate to this path inside File Explorer: C:/Windows/System32/driversetc
• After that, look for a file named “Hosts” and right-click on it, and open it with the Notepad app.
• Next, make sure that you write the block URLs in your computer in the list and then save the file.

Note: There are times when you are logged in with administrator credentials and you may receive an error message. In such case, type “notepad” in the Start Search and right-click on Notepad from the search results, and then select the “Run as administrator” option. After that, open the Hosts file and make the necessary changes and save it.

Option 2 – Try to check the Proxy server

There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. Follow the steps below to disable the proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 3 – Try to use the Registry Editor

Before you apply some registry tweaks, make sure that you create a System Restore point. Once you have that covered, follow these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersDataBasePath
• Look for the default key and double click on it and make sure that its Value data is set as “C:/Windows/System32/driversetc”.
• Now exit the Registry Editor and restart your computer to apply the changes made

Option 4 – Flush the DNS cache

You could also try to flush the DNS cache to fix the “ERR_ICAN_NAME_COLLISION” error. All you have to do is open Command Prompt as an administrator and then execute each one of the following commands sequentially to flush the DNS cache:

• ipconfig/release
• ipconfig/renew
• ipconfig/flushdns

Option 5 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Option 6 – Run a malware scan using Windows Defender

It is possible that your computer is infected with malware which could be why you’re getting the “ERR_ICAN_NAME_COLLISION” error. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

Sharing is caring, an old saying says. I completely agree and that is reason enough for this article filled with sharing goodness. Holidays are coming and I hope that the holiday spirit is strong with you, that you will spend them in peace and with loved ones. All that being said wouldn’t it be great if you can spend some joy with close ones and share some of your games on their account so they can enjoy them as well? Well, you can and it is not complicated as well. Follow this easy guide to see how can you get someone’s account up and running with some of your games.

Option 5 – Try to physically check the hardware

You should also check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card of the computer. You might want to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

Windows 10 has a pre-installed Weather app that offers the local weather information, forecast, temperature gradient, historical data, multiple locations, and many more. It can be handy especially if you tend to check on the weather. However, if you are one of those users who barely use this app, you have the option to uninstall it from your computer and that’s exactly what we’re going to do in this post. There are several methods to uninstall the Weather app in Windows 10. You can uninstall it via Settings or Start Menu or even using a command in Windows PowerShell. Note that uninstalling the Weather app does not affect the functionality of your Windows 10 computer by any means so you shouldn’t worry about uninstalling it. To get started, follow the instructions provided below.

Option 1 – Uninstall the Weather app through Settings

The first option you can try to uninstall the Weather app is through Settings. It’s a very simple process so you wouldn’t have any trouble following it.

• First, click on the Start menu and go to Settings.
• From there, select System > Apps & Features.
• After that, wait until the list of apps is opened, and then look for the Weather app and click on it.

If the Task Manager is either blank or is not showing processes on your Windows 10 computer, then here are a few things you can do to resolve this issue. This kind of problem can occur due to some system file corruption or some malware infection in the system. Here are some suggestions you can try to resolve the problem with the Task Manager on your Windows 10 PC.

Option 1 – Try restarting your computer

The most common and most of the time effective way to resolve this kind of issue is to simply restart your computer. Thus, you have to restart your computer and see if it helps in fixing the Task Manager issue or not. If not, you can try the next given options below.

Option 2 – Run the DISM tool

If the first option didn’t work, then running the Deployment Imaging and Servicing Management tool can help you resolve the issue with the Task Manager as it will repair the Windows System Image as well as the Windows Component Store in Windows 10.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• Next, type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Make sure that the display columns are selected in the Task Manager

You have to make sure that you have checked or selected the display columns you want to be displayed. So if none of them are selected, you might not see any details at all. Thus, you need to right-click on the space near Name and select the columns.

Option 4 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the reason why the Task Manager is blank or is not showing processes. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

Option 5 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Task Manager issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 6 – Try scanning your computer using Windows Defender

As mentioned, the Task Manager issue might be caused by some malware in the system and so to eliminate the malware, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms. 

So what’s phishing exactly, how can you detect it and how can you keep safe?

What is phishing?

Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.

Phishing techniques

E-mail phishing

This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.

Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.

SMS and social media phishing

Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.

Voice phishing

Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.

Spear phishing, whaling and BEC

Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.

Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).

In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.

What can you do?

There are many ways you can be aware and spot a phishing attempt. Here are some tips:

• Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
• In any instance where payment information is requested, be very, very careful.
• If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them. 
• Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
• Bad spelling and grammar are usually a telltale sign of phishing.
• Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
• If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
• Always examine first-time senders in detail.
• Block suspicious e-mail addresses, numbers and social media accounts.
• If you are receiving a coupon for free stuff… You aren’t.
• If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.

Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.

Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.

Summary

Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!
