Abstract: A strip of material for covering a ridge of a roof. The strip includes a color pattern applied to a surface of the strip to simulate multiple individual ridge shingles overlapping one another. The strip may be folded to simulate a layered effect created by the multiple individual ridge shingles. Adhesive may be applied to a surface of the strip to secure the strip to the ridge of the roof. The strip may also be attached over installed shingles with nails or staples.

Abstract: Compositions include an aqueous solution of an organic dye of molecular weight in the range of about 300 to about 1,000 and a density-enhancing material. An amount of the density-enhancing material in the aqueous solution is sufficient to achieve a density of about 1.0 to about 1.3 g/mL. The composition has a viscosity of about 3.5 to about 5.0 centipoise. The compositions are useful in assessing the adequacy of a liquid handling mixing device to mix a reaction mixture.

Abstract: Systems and methods for validating operation of a compiler are disclosed. One method includes receiving a definition of language syntax at an automated source code generator, and generating program code at the automated source code generator, the program code represented in source code including constructed self-validating code and syntactically-correct automatically generated code. The method also includes providing the source code to the compiler to be compiled into object code. Based on execution of the self-validating code as object code in a computing system, a computing system executing the object code outputs an indication of the correctness of compilation of the program code.

Abstract: A server hosting system provides managed servers for tenants of the server hosting system. Managed servers for different tenants can have the same IP addresses and fully-qualified domain names (FQDNs). Furthermore, the server hosting system provides routers for the tenants. The router for a tenant can receive a Domain Name System (DNS) update message. The DNS update message is a request for a DNS server to associate a tenant-side FQDN with a tenant-side IP address. This tenant-side IP address can concurrently be an IP address of a managed server of another tenant. In response to receiving the DNS update request, the router sends a DNS data message to a management system for the server hosting system. The DNS data message indicates the IP address, the tenant-side FQDN, and an IP address only associated with the given tenant.

Abstract: A server hosting system provides managed servers for tenants. Managed servers for different tenants can have the same IP addresses and fully-qualified domain names. A server manager for the server hosting system detects a deletion event for one of the managed servers. In response to detecting the deletion event, the server manager sends a web services request to a Domain Name Service (DNS) web service having a web API. The web services request requests invocation of a deregister method in the web API. The deregister method removes DNS records that associate a management-side fully qualified domain name (FQDN) for the managed server with a management-side IP address for the managed server. No other managed server in the server hosting system has the management-side IP address. No other managed server in the server hosting system has the management-side FQDN.

Abstract: A server hosting system provides managed servers for tenants. Managed servers for different tenants can have the same IP addresses and fully-qualified domain names (FQDNs). A management system of the server hosting system receives a DNS data message from a tenant router in the server hosting system. The DNS data message specifies an IP address of one of the managed servers, a tenant-side FQDN for the managed server, and an IP address of the tenant router. The managed server and the tenant router are associated with a given tenant. The IP address is also an IP address of another one of the managed servers. In response, the management system obtains a management-side IP address and a management-side FQDN for the managed server. The management system then updates a Domain Name System (DNS) record to associate the management-side FQDN with the management-side IP address.

Abstract: A safety system for mining equipment is provided having a proximity-based system with a marker field generator in an explosion-proof housing. The generator has a resonant circuit with an inductive reactance that is provided by a ferrite rod wound with an electrical conductor. Also provided is an RF receiver to receive information about the strength of the generated marker field from a sensing device used by a worker. The system provides for a personal alert device, carried by personnel to be kept at a safe distance from the mining machine, the personal alert device being capable of detecting the marker field. Also disclosed is a geosteering system that stops the cutting of a continuous miner when the cutter reaches an interface between a mineral being mined and an adjacent formation that is not to be mined.
