Better Rifling calc How To Find the Ideal Twist Rate for Your Rifle Matching Rifle Twist Rate to Caliber bullets. Twist Rate Electroplating Etching

 https://www.everydaymarksman.co/equipment/rifling-twist-rate/

A newer technology, Electrolytic Cationic Machining, uses a wet-etching method that uses reverse-electroplating to remove from inside the barrel rather than add to it. These machines utilize electrodes shaped as plastic cylinders with reverse-imaged metal strips encircling them. To create the desired twist rate, the cylinder is pushed through the barrel while the barrel is immersed in chemicals like sodium nitrate and methodically rotated. Although this is an expensive method of rifling, it results in precise rifling.

DCCP SCTP TFRC TCP UDP classifies protocol

 https://datatracker.ietf.org/doc/rfc8095/

 

 This document describes, surveys, and classifies the protocol
   mechanisms provided by existing IETF protocols, as background for
   determining a common set of transport services.  It examines the
   Transmission Control Protocol (TCP), Multipath TCP, the Stream
   Control Transmission Protocol (SCTP), the User Datagram Protocol
   (UDP), UDP-Lite, the Datagram Congestion Control Protocol (DCCP), the
   Internet Control Message Protocol (ICMP), the Real-Time Transport
   Protocol (RTP), File Delivery over Unidirectional Transport /
   Asynchronous Layered Coding (FLUTE/ALC) for Reliable Multicast, NACK-
   Oriented Reliable Multicast (NORM), Transport Layer Security (TLS),
   Datagram TLS (DTLS), and the Hypertext Transport Protocol (HTTP),
   when HTTP is used as a pseudotransport.  This survey provides
   background for the definition of transport services within the TAPS
   working group.

USB HID Test 4176 In the book "PIC microcontrollers for beginners" published by Elektor is to present how to dialogue through the USB port in HID mode. The source of the Windows executable is written under Delphi 7. Delphi 7 is no longer installable on new versions of Delphi. The project is to rewrite the project under Lazarus (freeware) to make the project usable by everyone.
