2. Change the VPN protocol

Your VPN protocol is like the lane your traffic travels in: some are faster than others. Start with WireGuard for the best balance of speed and security. If that’s blocked, try OpenVPN with UDP (good for streaming and...

After the launch of Google Pixel 7 and Pixel 7 Pro some months ago, the search giant is taking a different path from the regular flagship phones. Rather than offering the best possible hardware for performance, the company keeps betting on the Pixel series’ major highlight – the camera. For years, the lineup has been focusing on the camera department, and that pays off! The Pixel smartphones don’t have the most advanced hardware in the world, but they still deliver some of the best photographs in the smartphone scene.

Frequent jams slowed typing and frustrated users.
So the layout was redesigned to separate commonly used letter pairs.
Letters that often appear together were spaced apart to reduce mechanical interference.
The result was the QWERTY layout, popularized by Christopher Latham Sholes...

🔐 Chrome is testing a new model of HTTPS certifications in preparation for the post-quantum era.
In a proactive step against the risks of quantum computing, Google Chrome is testing what’s known as Merkle Tree Certificates (MTCs) — a radically different mechanism than the traditional X.509 certification model.
The problem is clear: Integrating post-quantum signature algorithms within the X.509 series will result in a significant boom in certificate volume, meaning a significant increase in TLS handshake data and a direct impact on performance.
The suggested solution is based on the structure of Merkle Tree:
Instead of the credentialing book signing...
