Abstract: A magazine-style wrench that laterally feeds multiple nuts down a magazine-style rail into a hexagonal head for dispensing and tightening. As a bolt is inserted into the hexagonal opening the threads of the bolt mesh into those of the nuts. The compressional force provided by a rectangular spring provides the necessary force to push the row of nuts forward and prevent the nut held in the opening from unintentionally falling out of the tool. The tool can be used to repeatedly tighten nuts onto bolts without personal handling. When out of nuts, the tool can be refilled and used again.

Abstract: An origin server that is implemented within one or more devices within a third party virtual private cloud (VPC) is provided herein. Instead of communicating with various CDNs over a public network, the third party VPC may instead communicate with a managed VPC via a private network. Thus, no gateway, network address translation (NAT), or other such devices may be needed for the third party VPC and the managed VPC to communicate. Rather, a VPC identifier of the managed VPC and a VPC identifier of the third party VPC are used to pair the two VPCs. Once paired, a private route is set up such that points from the private address space of the third party VPC to the private address space of the managed VPC. The managed VPC then communicates directly with the various CDNs via a public network.
