Method and apparatus for facilitating substitution of digital images with line drawings
One embodiment of the present invention provides a system that facilitates substitution of a full bitmap version of a graphical image with a line drawing version of the graphical image in a graphical presentation. The system operates by displaying a page in the graphical presentation, which includes the line drawing version of the graphical image.

Non-disruptive methods for updating a controller of a storage system
A non-disruptive method for updating firmware in a first controller 210 of a redundant controller 200 in a storage subsystem 120 is disclosed. This updating occurs while the storage subsystem 120 presents data to a host system 130 in response to a host request 132. During the non-disruptive updating, the updating first controller 210 redirects the host request 132 for data, e.g., drive-A volume 252 normally owned by the first controller 210, to second controller 220 of the redundant controller 200. After the second controller 220 obtains data 134 identified in the host request 132, the operating second controller 220 transfers the data 134 to the updating first controller 210 via an inter-controller channel 202. Once the updating first controller 210 receives the data 134, the first controller 210 presents the data 134 to the host system 130. The host system 130 does not detect that the first controller 210 is updating because the updating process is invisible to the host system 130. The above process is also applied when the updating is simply a reboot command for the first controller 210.

The method identifies a control point identifier that is associated with the service and determines, based on the one or more parameters, a mapping table storing data. The data identifies one or more customization code segments. The method loads the determined mapping table into a memory of the server and identifies one of the customization code segments that corresponds to the control point identifier. The method further loads the identified customization code segment into the memory of the server and calls the identified customization code segment inline during execution of the service. A response is transmitted to the client, based on the execution.
Method of data collection among participating content providers in a distributed network
A content delivery network (CDN) service provider extends a content delivery network to gather information on atomically identifiable web clients (called “user agents”) as such computer-implemented entities interact with the CDN across different domains being managed by the CDN service provider. In one embodiment, a set of machines, processes, programs, and data comprise a data system. The data system tracks user agents, preferably via cookies, although one or more passive techniques may be used. A user agent may be a cookie-able device having a cookie store. As the user agent navigates across sites, a CDN-specific unique identifier used by the system to correlate user agents is generated. Preferably, the unique identifier is stored as an encrypted cookie. The unique identifier represents one user agent (and, thus, one cookie-able device's store). The system tracks user agent behavior on and across customer sites that are served by the CDN, and these behaviors are classified into identifiable “segments” that may be used to create a profile. CDN customers use the data system to obtain information that characterizes the user agent.

Shared namespace for storage clusters
Any client application uses a namespace application to resolve its pathname in order to reference a computer file. Computer files are stored in a fixed-content storage cluster and are accessed by retrieving a unique identifier for the computer file using the namespace application. Any type of pathname scheme from any client application is supported by the namespace. The namespace application uses a bindings table to record bindings between objects including the start date and end date for each binding, and direction and separator data used in the pathname scheme. An attribute table in the namespace keeps track of each attribute and its value for each object of the namespace including a start date and an end date for each attribute. The namespace provides syntactic generality in that any pathname scheme of a client application can be resolved to identify a unique computer file in the storage cluster. The namespace may be shared between applications because when one application modifies a file or its attributes using the namespace, another application using a different pathname scheme has access to the exact same data and modifications. The namespace provides a near instantaneous continuous backup for computer files in the storage cluster because of the use of start date and end dates for the bindings and attributes.

Receiving apparatus, transmitting apparatus, reception method, and transmission method
A reception unit receives data from communication apparatuses. A transmission unit transmits data to the communication apparatuses. A control unit determines, in an adaptive way, which modulation and coding schemes to use to transmit and receive data. At a first stage, a modulation and coding scheme with a low transmission rate or a modulation and coding scheme that minimizes power requirements is selected from among a plurality of candidates therefor. At a second stage, the modulation and coding scheme of at least one of the communication apparatuses is changed to another scheme having a higher transmission rate, when it is impossible to allocate sufficient resources for the modulation and coding schemes selected at the first stage.
