Error: 500 {"error":"[ethjs-query] while formatting outputs from RPC '{"value":{"code":-32603,"message":"Too Many Requests","data":{"originalError":{}},"stack":"Error: Too Many Requests\n at eval (/www/node_modules/web3-provider-engine/subproviders/rpc.js:52:23)\n at Request.eval [as _callback] (/www/node_modules/web3-provider-engine/subproviders/rpc.js:54:11)\n at Request.self.callback (/www/node_modules/request/request.js:186:22)\n at Request.emit (events.js:315:20)\n at Request.eval (/www/node_modules/request/request.js:1155:10)\n at Request.emit (events.js:315:20)\n at IncomingMessage.eval (/www/node_modules/request/request.js:1077:12)\n at Object.onceWrapper (events.js:421:28)\n at IncomingMessage.emit (events.js:327:22)\n at endReadableNT (internal/streams/readable.js:1327:12)"}}'"}
this is the error i am getting when I try to transfer test ethereum to my metamask wallet from the test faucet https://faucet.metamask.io/
You can use other faucet for Ropsten testnet like these:

description: Attempt an operation multiple times if it fails due to network or server errors.
I have used apollo-link-retry to retry calls on the occurrence of server errors(5xx).
But when 400 error(bad request) is occurring it retrying which is expected to retry in server error only.
Does network error means all client errors(4xx) and server errors(5xx)?
How to stop retrying on errors other than 5xx?
In the context of Apollo Client, there are two types of errors -- GraphQL errors (those returned inside the errors array in the response) and network errors. Any request that returns a status other than 200 is considered to have encountered a network error. The default RetryLink configuration is not that granular -- it only cares about whether a network error occurred, not what kind of error occurred. If you want to not retry on certain errors, provide a retryIf function to the attempts configuration as shown in the docs:
attempts: {
retryIf: (error, _operation) => {
// return true or false depending on the properties on error
}
}
})

is there a way to use speech recognition in an Iionic 2 Project? All I came across are possibilities for Ionic 1 like in this post Speech recognition using ionic framework . Ionic 2 already provides a native API for Text to Speech http://ionicframework.com/docs/v2/native/texttospeech/ but I would need it the other way round.
Better question to ask yourself is, is there a cordova plugin for the thing I want?
And yes there are cordova plugins available.
https://github.com/macdonst/SpeechRecognitionPlugin
https://github.com/poiuytrez/SpeechRecognizer
Just instead of using cordova plugin add ..... use ionic plugin add ...... (will immediately update platforms).
You can use this Cordova plugin for speech recognition cordova-plugin-tts
Since Ionic 2 uses TypeScript ,all you need is a way to use the plugin with TypeScript .The Github repo includes an example on how to do that
declare module TTS {
interface IOptions {
/** text to speak */
text: string;
/** a string like 'en-US', 'zh-CN', etc */
locale?: string;
/** speed rate, 0 ~ 1 */
rate?: number;
}
function speak(options: IOptions, onfulfilled: () => void, onrejected: (reason) => void): void;
function speak(text: string, onfulfilled: () => void, onrejected: (reason) => void): void;
}

I tried boto api and seems that no api can get message number already in flight? Does anyone give me a hint how to get this number?
To find the messages in flight or any of the other attributes of an SQS queue in boto, you need to do this:
import boto.sqs
c = boto.sqs.connect_to_region('us-east-1')
queue = c.lookup('myqueue')
attr = queue.get_attributes()
This will a python dictionary that looks like this:
{u'ApproximateNumberOfMessages': u'0',
u'ApproximateNumberOfMessagesDelayed': u'0',
u'ApproximateNumberOfMessagesNotVisible': u'0',
u'CreatedTimestamp': u'1412270007',
u'DelaySeconds': u'0',
u'LastModifiedTimestamp': u'1412270007',
u'MaximumMessageSize': u'262144',
u'MessageRetentionPeriod': u'345600',
u'QueueArn': u'arn:aws:sqs:us-east-1:723405645490:16ac1da3-564c-43aa-8dcb-4db41ece50ea',
u'ReceiveMessageWaitTimeSeconds': u'0',
u'VisibilityTimeout': u'30'}
I believe the ApproximateNumberOfMessagesNotVisible is equivalent to the in-flight statistic reported by the console.

I am on project right now which is a very simple parental control software, but, I want to know what is the url requested in firefox to take respond based on it ... if you may help because I don't know how to let my software know what is the url requested by firefox .. How to do that?
I have to use C++ in most of my software.. but if there are better language to do this task please advice me
In Firefox you need to use XPCOM component called nsIHTTPChannel. This script below will block abort all rqeuests to google. The channel is opened but aborted before opening connection to server.
var {classes: Cc, results: Cr, utils: Cu} = Components;
Cu.import('resource://gre/modules/Services.jsm');
var httpRequestObserver =
{
observe: function(subject, topic, data)
{
var httpChannel, requestURL;
if (topic == 'http-on-modify-request') {
httpChannel = subject.QueryInterface(Ci.nsIHttpChannel);
requestURL = httpChannel.URI.spec;
if (/google\.com/.test(requestURL)) {
httpChanel.cancel(Cr.NS_BINDING_ABORTED);
}
return;
}
}
};
Services.obs.addObserver(httpRequestObserver, 'http-on-modify-request', false);
//Services.obs.removeObserver(httpRequestObserver, "http-on-modify-request", false); //run this to remove observer
Can I suggest an alternative approach? Instead of writing an extension for Firefox and an extension for Chrome and an extension for IE... listen on the OS network interfaces for traffic and block undesirable URLS.
This is traditionally the job of a firewall. Using an existing solution will provide the most efficient means of solving your problem. I'm not familiar with the capabilities of the built in Windows firewall or 3rd party alternatives but something like this would be trivial with iptables (Linux).

I have the following behaviour with Ember Data 1.0.0 Beta 2:
Rollback of data changes (without first trying to save the changes):
- all data properties are restored to the previous version
- all flags in correct state
Rollback of data changes after an attempt to save, but the save returned a 422 error:
- none of the data properties are restored
- isError flag remains true
I would expect that also in the second case the properties are set back to the previous state and that the isError flag is cleared.
This is how I revert:
cancel: function () {
var author = this.get('model');
author.rollback();
},
Is this a known issue ?
thx
