Windows 11 might tank Ryzen CPU performance, AMD warns

Oct 11, 2021 - 8:09 PM - by Reverend
AMD said Windows 11 can cut game performance on Ryzen CPUs by 10 to 15 percent, and the operating system may not utilize AMD’s “preferred core” technology, but a fix in the works.

A support note on AMD’s web site published this week said Windows 11 may increase L3 cache latency a whopping threefold, which can cause slowdowns in latency sensitive applications. Lighter duty, cache-sensitive games might see a 3 percent to 5 percent hit, and lighter-duty games as e-sports titles could see frame rates drop from 10 to 15 percent.

AMD also said its “preferred core” feature, which tells the operating system which core in each CPU can hit the highest clock, also doesn’t work right in Windows 11. Each CPU is tested to see which core will run the fastest at the factory and is marked so the OS will dispatch tasks to that “preferred core.” Since Windows 11 doesn’t seem to work with it right now, any performance bump from using the best core wouldn’t happen. The company said the performance cost would be most noticeable in CPUs with more than 8 cores and with TDP ratings above 65 watts.

AMD said both Microsoft and it are working on an update to Windows 11 that should address both issues this month.

Facebook, Instagram and WhatsApp coming back online after major outage

Oct 05, 2021 - 9:12 AM - by Reverend
Facebook Engineering have issued a statement regarding the October 4th outage that affected Facebook, Instagram, WhatsApp services.

To all the people and businesses around the world who depend on us, we are sorry for the inconvenience caused by today’s outage across our platforms. We’ve been working as hard as we can to restore access, and our systems are now back up and running. The underlying cause of this outage also impacted many of the internal tools and systems we use in our day-to-day operations, complicating our attempts to quickly diagnose and resolve the problem.

Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication. This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt.

Our services are now back online and we’re actively working to fully return them to regular operations. We want to make clear at this time we believe the root cause of this outage was a faulty configuration change. We also have no evidence that user data was compromised as a result of this downtime.

People and businesses around the world rely on us everyday to stay connected. We understand the impact outages like these have on people’s lives, and our responsibility to keep people informed about disruptions to our services. We apologize to all those affected, and we’re working to understand more about what happened today so we can continue to make our infrastructure more resilient.

Amazon to unveil latest Echo, Ring devices on Sept. 28

Sep 21, 2021 - 8:39 AM - by Reverend
Amazon is hosting an event next week to show off the latest editions to its growing lineup of Ring, Fire TV and Echo devices as well as updates on its services. The virtual event will take place on Sept. 28.

Amazon's invite on Monday didn't reveal much, but the retail giant could unveil updated versions of its Echo smart speakers and displays. During its fall devices and services event last year, Amazon unveiled the spherical fourth-gen Echo, Echo Dot and Echo Dot Kids Edition as well as the Echo Show 10.

Another thing we could get next week: a release date for the Ring Always Home Cam. Amazon introduced the $250 indoor drone -- a flying security camera that docks when it isn't in use -- during its event last year but didn't give a specific release date.

It's unclear if Amazon will have more in store for Fire TV. Earlier this month, the company debuted a new standalone streamer, the Fire TV Stick 4K Max, as well as the Amazon Fire TV Omni and Fire TV 4-Series. The new Amazon-built TVs are available for preorder and slated to arrive in October.

Microsoft will now let its users log in without passwords

Sep 17, 2021 - 7:32 AM - by Reverend
Microsoft has a solution for the familiar problem of needing to remember too many passwords: doing away with them altogether.

The company announced Wednesday that it will introduce a "passwordless account" option for all users of several popular services such as Microsoft Outlook and Microsoft OneDrive in the coming weeks. Microsoft previously made this option available to corporate accounts in March.

"You can now completely remove the password from your Microsoft account," Vasu Jakkal, the company's corporate vice president of security, compliance and identity, wrote in a blog post Wednesday.

Instead of passwords, Microsoft will let users sign in to these services with either the company's Authenticator app, which produces a unique numbered login code every few seconds, or with Windows Hello, which lets users sign in using facial recognition, a fingerprint or a unique pin. Microsoft users can also buy an external security key, like a USB drive with login information stored on it, or register a phone number to which Microsoft sends a verification code.

The change from Microsoft comes after a spike in cyberattacks over the past year. With the majority of corporate employees working from home because of the coronavirus pandemic, hackers have many more avenues to infiltrate a company's systems — and compromising passwords is one of their most common strategies. (Microsoft has also had its share of security issues in recent months, with its services linked to multiple high-profile hacks and breaches.)

Passwords can often end up for sale on the dark web, where they are bought and used to hack even more services. Hackers have even gone after password managers that aim to make login data more secure, with popular service LastPass hacked in 2015.

According to Microsoft, 579 password attacks take place every second, adding up to 18 billion attacks a year. And cybersecurity experts have said the weakest link is human behavior — our tendency to re-use the same password across accounts so it's easy to remember, or create patterns for different passwords that are easy for hackers to guess.
"Weak passwords are the entry point for the majority of attacks across enterprise and consumer accounts," Jakkal said.

Microsoft appears to be leading by example in its effort to pioneer a passwordless future. According to Jakkal, almost all of the company's own employees now log into their corporate accounts without passwords.

Mozilla has defeated Microsoft’s default browser protections in Windows

Sep 14, 2021 - 9:56 AM - by Reverend
Mozilla has quietly made it easier to switch to Firefox on Windows recently. While Microsoft offers a method to switch default browsers on Windows 10, it’s more cumbersome than the simple one-click process to switch to Edge. This one-click process isn’t officially available for anyone other than Microsoft, and Mozilla appears to have grown tired of the situation.

In version 91 of Firefox, released on August 10th, Mozilla has reverse engineered the way Microsoft sets Edge as default in Windows 10, and enabled Firefox to quickly make itself the default. Before this change, Firefox users would be sent to the Settings part of Windows 10 to then have to select Firefox as a default browser and ignore Microsoft’s plea to keep Edge.

Mozilla’s reverse engineering means you can now set Firefox as the default from within the browser, and it does all the work in the background with no additional prompts. This circumvents Microsoft’s anti-hijacking protections that the company built into Windows 10 to ensure malware couldn’t hijack default apps. Microsoft tells us this is not supported in Windows.
Firefox now makes it easy to switch default browsers in Windows.

Mozilla has clearly grown tired of the more complicated way of setting up a default browser, a process that Microsoft is making even harder in Windows 11. “People should have the ability to simply and easily set defaults, but they don’t,” says a Mozilla spokesperson in a statement to The Verge. “All operating systems should offer official developer support for default status so people can easily set their apps as default. Since that hasn’t happened on Windows 10 and 11, Firefox relies on other aspects of the Windows environment to give people an experience similar to what Windows provides to Edge when users choose Firefox to be their default browser.”

Mozilla has been trying to convince Microsoft to improve its default browser settings in Windows since its open letter to Microsoft in 2015. Nothing has changed, and Windows 11 is now making it even harder to switch default browsers. That appears to be the final straw, as Mozilla began implementing its changes in Firefox shortly after the Windows 11 unveiling in June.
