Huawei joins major US-based open-source patent protection consortium OIN

When you think of Chinese 5G smartphone superpower Huawei and intellectual property (IP), your first thoughts are of the US Department of Justice charging Huawei with racketeering and conspiracy to steal trade secrets. Or, if you follow intellectual property (IP) issues closely, you’d recall that Huawei has made $6 billion in patent royalties since 2001 with nearly 80% of that coming from US companies.

Content Delivery Networks and clouds join MANRS internet security effort

So far, the internet is holding up underneath the unprecedented demands being put on it by the coronavirus pandemic. But, as the recent Google services failure from a single router failure showed, the internet remains fragile. That’s why the Internet Society and the Mutually Agreed Norms for Routing Security (MANRS) initiative have started the Content Delivery Network (CDN) and Cloud Programme “to help secure large hubs of the Internet from common routing problems.”

Linux’s WireGuard VPN is here and ready to protect you

Linus Torvalds has released the newest version of the Linux 5.6. It includes many new and neat features like USB4 support, a fix for the 32-bit Epoch problem, multi-path TCP, and numerous driver patches. The biggest news of all s that Linux now has the popular open-source Virtual Private Network (VPN) WireGuard baked in.

WireGuard is a radical new approach to VPNs. With its minimal codebase — about 4,000 lines of code — it’s much easier to debug and secure than its rivals such as OpenVPN with its over 100,000 lines.

Coronavirus: The Cold Equations

John Hopkins Coronavirus US Map March 28, 2020

Some people in my life are still having trouble believing the Coronavirus is all that bad. Actually, it’s worse than many can imagine. Let’s look at some cold, hard numbers.

 Yesterday, March 27, we went over 100,000 cases in the US. In the States we currently have a doubling rate of four days. That means by April 12, Easter, we’ll have well over a million cases.

 The death count, 367 yesterday. is doubling every three days. And, that’s without our hospitals cracking under the strain. It’s all too likely, without beds and sufficient resources of even basic supplies such as N95 masks–never mind urgent care beds and ventilators–our hospitals will buckle and the death rate will spike. 

 Even without that, by April 12, the cold hard numbers say we’ll be seeing well over 10,000 deaths a day. We are Not going back to work, church, or normal life by then, no matter what anyone tells you.
