WireGuard: fast, modern, secure VPN tunnel
WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.

FEL - linux-sunxi.org
FEL is a low-level subroutine contained in the BootROM on Allwinner devices. It is used for initial programming and recovery of devices using USB.

Sticky-note-pin.png Your device therefore needs to be attached to a host (your PC) by means of a USB cable, connected to a port where the sunxi device will present itself as a USB 'slave' (i.e. in device mode). Usually that means the "OTG" connector.[1]

NXDOMAIN, NODATA and debugging DNS for dual-stacked hosts - Cisco Umbrella Blog
TL;DR – An NXDOMAIN response means there are no records, of any DNS type, for the requested domain name. A NODATA response means there are records for the requested domain name, but none of them match the record type in your request.

ssl certificate - SSL encryption with CNAME redirect - Server Fault
Q: Here is my current architecture: I have a simple site hosted in the cloud that needs to be served from my company. Thus, mysite.com has a CNAME redirect to 1234.cloud.com. I understand that the SSL certificate needs to be created for mysite.com.

Here are my questions:

a) how does the CNAME redirect work when fetching content? does DNS resolve the cloud IP address and allow just one HTTP connection to the cloud or is the HTTP connection sent to my server and then relayed to the cloud? which server presents the SSL cert for mysite.com? I believe that I need to configure a local server to offer the SSL certificate because DNS alone would not suffice, but I am not sure on the architecture. [...]

RFC 7230 - Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing
The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document provides an overview of HTTP architecture and its associated terminology, defines the "http" and "https" Uniform Resource Identifier (URI) schemes, defines the HTTP/1.1 message syntax and parsing requirements, and describes related security concerns for implementations.

Using HAProxy with the Proxy Protocol to Better Secure Your Database - HAProxy Technologies
The Proxy protocol is a widely used invention of our CTO at HAProxy Technologies, Willy Tarreau, to solve the problem of TCP connection parameters being lost when relaying TCP connections through proxies. Its primary purpose is to chain proxies and reverse-proxies without losing client information, and it’s used and supported by AWS ELB, Apache, NGINX, Varnish, Citrix, and many more (here’s a longer list of Proxy protocol supported technologies).

The X-Forwarded-For (XFF) HTTP header field was a common method for identifying the originating IP address of a client connecting to a web server through an HTTP proxy or load balancer. As of 2014 RFC 7239 standardized a new Forwarded header with similar purpose but more features compared to XFF.[1] An example of a Forwarded header syntax: [...]

Representational state transfer - Wikipedia, the free encyclopedia
In computing, representational state transfer (REST) is the software architectural style of the World Wide Web.[1][2][3] REST's coordinated set of constraints, applied to the design of components in a distributed hypermedia system, can lead to a higher-performing and more maintainable software architecture.

Protocol Buffers — Google Developers
Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages – Java, C++, or Python.

Protocol Buffers - Wikipedia, the free encyclopedia
Protocol Buffers are a method of serializing structured data. They are useful in developing programs to communicate with each other over a wire or for storing data. The method involves an interface description language that describes the structure of some data and a program that generates source code from that description for generating or parsing a stream of bytes that represents the structured data.

How Proxied Torrents Could End ISP Subpoenas - Slashdot
"With the announcement of Verizon's "six strikes plan" for movie pirates (which includes reporting users to the RIAA and MPAA), and content companies continuing to sue users en masse for peer-to-peer downloads, I think it's inevitable that we'll see the rise of p2p software that proxifies your downloads through other users. In this model, you would not only download content from other users, but you also use other users' machines as anonymizing proxies for the downloads, which would make it impossible for third parties to identify the source or destination of the file transfer. This would hopefully put an end to the era of movie studios subpoenaing ISPs for the identities of end users and taking those users to court."
Read below for the rest of Bennett's thoughts.

The NTP Timescale and Leap Seconds
The timescale used by the Network Time Protocol (NTP) is based on coordinated univeral time (UTC), which itself is based on the Earth rotation about its axis. As the rotation of the Earth is slowing very gradually, this requires a leap second to be inserted in the timescale at approximately eighteen month intervals. This document describes the mechanics of insertion and how it affects the timescale shortly before, during and after the leap second.

Transport Layer Security - Wikipedia, the free encyclopedia
Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols that are designed to provide communication security over the Internet.[1] They use X.509 certificates and hence asymmetric cryptography to assure the counterparty whom they are talking with, and to exchange a symmetric key. This session key is then used to encrypt data flowing between the parties. This allows for data/message confidentiality, and message authentication codes for message integrity and as a by-product message authentication. Several versions of the protocols are in widespread use in applications such as web browsing, electronic mail, Internet faxing, instant messaging and voice-over-IP (VoIP). An important property in this context is perfect forward secrecy, so the short term session key cannot be derived from the long term asymmetric secret key.[2]
