Google Joins The Evidence-Optional Assault On Huawei
So we've noted several times now how the US efforts to blacklist Huawei from global telecom markets haven't much in the way of, oh, supporting evidence. The Trump administration and FCC have taken all manner of actions to try and blackball the company, from pressuring U.S. carriers to drop plans to sell Huawei phones to the FCC's decision to ban companies from using Huawei gear if they want to receive federal subsidies.
The underlying justification for these moves has centered on the idea that Huawei operates as a surveillance extension of the Chinese government, something that still hasn't been proven despite a decade's worth of claims to this effect, and an eighteen month investigation by the White House.
That's not to say the Chinese government is an innocent little daisy. Nor is it meant to suggest that it's impossible that Huawei spies on Americans. But the lack of any actual public evidence of spying remains troubling all the same, given that if the shoe were on the other foot, there'd be no shortage of face-fanning consternation on the part of American politicians and industry.

In the last three days, we’ve received a whole bunch of questions like Should I disable Hyper-Threading or not? and How Hyper-Threading disabling can impact performance? So, here we are with some important information about the point.
But what is the problem? CPU has two execution threads per physical core. Both threads share the same resources inside the CPU. It means sibling cores can see the same data as the primary core can.

Is Linux Safer Than Windows and macOS?
Cybersecurity is extremely important – now more than ever. If you start to do research, however, you’ll find a debate going on about which operating system is the safest. These days, more IT professionals and companies are preaching the benefits of Linux systems. There are definitely some security advantages to the platform. But like everything in the computer world, so much comes down to user training. Even if you have a very secure platform, a virus can still be a problem. So let’s take a look at Linux and some of the advanced security measures you need to take.
