Error Signal . From Context

Community Go on Twitter Blog index The Go Blog Go Concurrency Patterns: Context 29 July 2014 Introduction In Go servers, each incoming request is handled in its own goroutine. Request error signal 15 is sent to script handlers often start additional goroutines to access backends such as databases and RPC services. error signal transfer function The set of goroutines working on a request typically needs access to request-specific values such as the identity of the end error signal 11 user, authorization tokens, and the request's deadline. When a request is canceled or times out, all the goroutines working on that request should exit quickly so the system can reclaim any resources they are using. error signal and the placement of ctenophora sister to all other animals At Google, we developed a context package that makes it easy to pass request-scoped values, cancelation signals, and deadlines across API boundaries to all the goroutines involved in handling a request. The package is publicly available as context. This article describes how to use the package and provides a complete working example. Context The core of the context package is the Context type: // A Context carries a deadline, cancelation signal,

and request-scoped values // across API boundaries. Its methods are safe for simultaneous use by multiple // goroutines. type Context interface { // Done returns a channel that is closed when this Context is canceled // or times out. Done() <-chan struct{} // Err indicates why this context was canceled, after the Done channel // is closed. Err() error // Deadline returns the time when this Context will be canceled, if any. Deadline() (deadline time.Time, ok bool) // Value returns the value associated with key or nil if none. Value(key interface{}) interface{} } (This description is condensed; the godoc is authoritative.) The Done method returns a channel that acts as a cancelation signal to functions running on behalf of the Context: when the channel is closed, the functions should abandon their work and return. The Err method returns an error indicating why the Context was canceled. The Pipelines and Cancelation article discusses the Done channel idiom in more detail. A Context does not have a Cancel method for the same reason the Done channel is receive-only: the function receiving a cancelation signal is usually not the one that sends the signal. In particular, when a parent operation starts goroutines for sub-operations, those sub-operations should not be able to canc

Prerequisites Requirements Cisco recommends that you read Troubleshooting Router Crashes before proceeding with this document. Components Used The information in this document is based on these http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-121-mainline/7949-crashes-buserror-troubleshooting.html software and hardware versions: All Cisco IOS® software versions All Cisco routers Note:This document does not apply to Cisco Catalyst switches or MGX platforms. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions Refer to the Cisco Technical Tips Conventions for more information on document conventions. Identifying Bus Error Crashes The system encounters a bus error when the processor tries to access a memory location that either does not exist (a software error) or does not respond properly (a hardware problem). A bus error can be identified from the output of the show version command provided by the router if not power-cycled or manually reloaded. If you have the output of a show version or show technical-support command (from enable mode) from your Cisco device, you can use it to display potential issues and fixes. In order to use it, you must be a registered customer, be logged in, and have JavaScript enabled. Router uptime is 2 days, 21 hours, 30 minutes System restarted by bus error at PC 0x30EE546, address 0xBB4C4 System imag

Current theories of visual change detection emphasize the importance of conscious attention to detect unexpected changes in the error signal . visual environment. However, an increasing body of studies shows that the human brain is capable of detecting even small visual changes, especially if such changes violate non-conscious expectations based on repeating experiences. In other words, our brain automatically represents environmental regularities. Since the discovery of the mismatch negativity component, the majority of research in the field focused on auditory deviance detection, and its neural correlate, the MMN response. However, automatic predictive (i.e. change detection) mechanisms operate in the visual modality too. An indicator of the automatic change detection is the visual mismatch negativity (vMMN) component of the event-related potentials (ERPs). VMMN is typically elicited by stimuli with infrequent (deviant) features embedded in streams of identical (standard) stimuli. vMMN is elicited independent of attention by deviant color, orientation, movement, spatial frequency, contrast, and has shown its potential also as a clinically relevant brain measure. Abstract sequential regularities of visual stimuli, and natural stimuli such as faces and hands have also been used to study automatic prediction error responses to unpredicted visual events. These studies confirmed that information about the content of both simple and more complex natural stimuli is rapidly processed and stored by the brain in the
