FCM: Message to multiple registration ids limit? | <p>As per this quote I found:</p>
<blockquote>
<ul>
<li><strong>registration_ids</strong> – Type String array – (Optional) [Recipients of a message]
Multiple registration tokens, min 1 max 1000.</li>
</ul>
</blockquote>
<p>Is this the actual limit of device tokens I can send a single message to? And do messages to topics have the same limit?</p>
<p>ex: </p>
<pre><code>{
"to": [reg_token_01, reg_token_02, ..., reg_token_1000],
"priority": "high",
"data": {
"title": "Hi Peeps!",
"message": "This is a special message for only for you... More details are available..."
}
}
</code></pre>
<p>As always, thanks for the info and direction!</p> | 0 |
How to send and receive custom data with AirDrop | <p>I've been struggling with this for ages now as I can't find any detailed examples.</p>
<p>In my app I have an array of custom data that I want to send to another user with the same app, via AirDrop.</p>
<p>The first step is sending the data:</p>
<pre><code>@IBAction func share_Button_Click(sender: UIBarButtonItem)
{
let dataToShare: NSData = getMyCustomNSData()
let controller = UIActivityViewController(activityItems: [dataToShare], applicationActivities: nil)
controller.excludedActivityTypes = [UIActivityTypePostToFacebook, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, UIActivityTypePostToFlickr, UIActivityTypePostToTencentWeibo, UIActivityTypeMail, UIActivityTypeAddToReadingList, UIActivityTypeOpenInIBooks, UIActivityTypeMessage]
self.presentViewController(controller, animated: true, completion: nil)
}
</code></pre>
<p>This converts my data to an NSData object, the user gets the AirDrop share option, and of the data goes to another phone. So far so good...</p>
<p>But how does the other user's app know how to receive it?</p>
<p>I've read about custom UTI types and have declared one, but to be honest I don't know what to put in the declaration. And how do you indicate to iOS that the data you are sending conforms to this particular UTI?</p>
<p>There are AirDrop examples here and there online, but they focus on sharing common types like images, and no one I have found has worked through sharing a custom data type in detail.</p>
<p>Can anyone help?</p> | 0 |
Move button when keyboard appears swift | <p>In a UIViewController I have several text fields and a button is on the bottom of the UIViewController.
For the button, I have set a bottom constraint with a constant of 0.
Then I made an outlet from the bottom constraint to the UIViewController. </p>
<p>When I run my code, the button does not move upwards. I have seen suggestions on stackoverflow that I should add UIScrollView, but that means, I would have to delete all the objects on the UIViewController, put the UIScrollView and then put my objects on the UIVIewController again. </p>
<pre><code>@IBOutlet weak var bottomConstraint: NSLayoutConstraint!
// When tapping outside of the keyboard, close the keyboard down
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
// Stop Editing on Return Key Tap. textField parameter refers to any textfield within the view
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
// When keyboard is about to show assign the height of the keyboard to bottomConstraint.constant of our button so that it will move up
func keyboardWillShow(notification: NSNotification) {
if let userInfo = notification.userInfo {
if let keyboardSize: CGRect = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
bottomConstraint.constant = keyboardSize.size.height
view.setNeedsLayout()
}
}
}
// When keyboard is hidden, move the button to the bottom of the view
func keyboardWillHide(notification: NSNotification) {
bottomConstraint.constant = 0.0
view.setNeedsLayout()
}

Comparison operator in PySpark (not equal/ !=) | <p>I am trying to obtain all rows in a dataframe where two flags are set to '1' and subsequently all those that where only one of two is set to '1' and the other <strong>NOT EQUAL</strong> to '1'</p>
<p>With the following schema (three columns),</p>
<pre><code>df = sqlContext.createDataFrame([('a',1,'null'),('b',1,1),('c',1,'null'),('d','null',1),('e',1,1)], #,('f',1,'NaN'),('g','bla',1)],
schema=('id', 'foo', 'bar')
)
</code></pre>
<p>I obtain the following dataframe:</p>
<pre><code>+---+----+----+
| id| foo| bar|
+---+----+----+
| a| 1|null|
| b| 1| 1|
| c| 1|null|
| d|null| 1|
| e| 1| 1|
+---+----+----+
</code></pre>
<p>When I apply the desired filters, the first filter (foo=1 AND bar=1) works, but not the other (foo=1 AND NOT bar=1)</p>
<pre><code>foobar_df = df.filter( (df.foo==1) & (df.bar==1) )
</code></pre>
<p>yields:</p>
<pre><code>+---+---+---+
| id|foo|bar|
+---+---+---+
| b| 1| 1|
| e| 1| 1|
+---+---+---+
</code></pre>
<p><strong>Here is the non-behaving filter:</strong></p>
<pre><code>foo_df = df.filter( (df.foo==1) & (df.bar!=1) )
foo_df.show()
+---+---+---+
| id|foo|bar|
+---+---+---+
+---+---+---+
</code></pre>
<p>Why is it not filtering? How can I get the columns where only foo is equal to '1'?</p> | 0 |

<p>So as you see it works fine, but only if parent element (<code>flex-row</code>) is set to size*2, because another way the size of children elements will be automatically reduced.</p> | 0 |

Setting the value of an Access combobox with VBA comparison | <p>I'm trying to figure out where I went wrong with this.</p>
<p>I have two tables <code>Request</code> and <code>Parent</code>. <code>Request</code> can only have one related <code>Parent</code> record, but <code>Parent</code> can have many related <code>Request</code> records. So I have the <code>Request</code> table containing the foreign key to <code>Parent</code>.</p>
<p>I have an unbound combobox that pulls it's data from the <code>Parent</code> table using a query (contains company name and ID bound to column 0 and 1, with column 1 being hidden so the user doesn't see the numeric ID). It's unbound because the form's recordset has a lot of complex joins, making anything on that form unable to be updated. So I created an "On Change" event on the combo box to fill in the foreign key using a querydef SQL update query:</p>
<pre><code>Private Sub Combo217_Change()
Dim ComboID As String
Dim ReqID As Long
Dim dbs As DAO.Database
Dim qdfUpdateParentExisting As DAO.QueryDef
ReqID = Me.RequestID.Value
ComboID = Me.Combo217.Column(1)
Set dbs = CurrentDb
Set qdfUpdateParentExisting = dbs.QueryDefs("UpdateReqExistingParent")
qdfUpdateParentExisting.Parameters("VBParent").Value = ComboID
qdfUpdateParentExisting.Parameters("VBReqID").Value = ReqID
qdfUpdateParentExisting.Execute
qdfUpdateParentExisting.Close
DoCmd.Save acForm, "DT2"
Me.Requery
End Sub
</code></pre>
<p>This works just fine, but once you exit the form and re-enter it, the value in the combo box is blank and I would like this to contain the same value that was selected.</p>
<p>I've been trying to do an "On load event" with the following code but it's not working</p>
<pre><code>Dim ParID
ParID = Me.ParentID.Value
Me.Combo217.Column(1).Value = ParID
</code></pre>
<p>Any input on getting this to work would be fantastic!</p> | 0 |
How to set heap size in spark within the Eclipse environment? | <p>I am trying to run the simple following code using spark within Eclipse:</p>

How to escape @ in a password in pymongo connection? | <p>My question is a specification of <a href="https://stackoverflow.com/questions/29508162/how-can-i-validate-username-password-for-mongodb-authentication-through-pymongo">how can i validate username password for mongodb authentication through pymongo?</a>.</p>
<p>I'm trying to connect to a MongoDB instance using PyMongo 3.2.2 and a URL that contains the user and password, as explained in <a href="https://docs.mongodb.com/manual/reference/connection-string/#standard-connection-string-format" rel="noreferrer">MongoDB Docs</a>. The difference is that the password I'm using contains a '@'.</p>
<p>At first I simply tried to connect without escaping, like this:</p>
<blockquote>
<p>prefix = 'mongodb://'</p>
<p>user = 'user:passw_with_@_'</p>
<p>suffix = '@127.0.0.1:27001/'</p>
<p>conn = pymongo.MongoClient(prefix + user + suffix)</p>
</blockquote>
<p>Naturally I got the following error:</p>
<pre><code>InvalidURI: ':' or '@' characters in a username or password must be escaped according to RFC 2396.
</code></pre>
<p>So I tried escaping the user:pass part using <a href="https://docs.python.org/2/library/urllib.html?highlight=urllib#urllib.quote" rel="noreferrer">urllib.quote()</a> like this:</p>
<blockquote>
<p>prefix = 'mongodb://'</p>
<p>user = urllib.quote('user:passw_with_@_')</p>
<p>suffix = '@127.0.0.1:27001/'</p>
<p>conn = pymongo.MongoClient(prefix + user + suffix)</p>
</blockquote>
<p>but then I got a:</p>
<pre><code>OperationFailure: Authentication failed.
</code></pre>
<p>(Important to say that using a GUI MongoDB Management Tool (<a href="https://robomongo.org/" rel="noreferrer">Robomongo</a>, if that matters) I'm able to connect to the MongoDB using the (real) address and credentials.)</p>
<p>Printing user variable in the code above generated a <code>'user:passw_with_%40_'</code> String (that is '@' became '%40') and according to <a href="https://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_reserved_characters" rel="noreferrer">wikipedia</a> that's the expected escaping.</p>
<p>I even tried escaping the @ with single and double backslashes (<code>user = 'user:passw_with_\\@_'</code> and <code>user = 'user:passw_with_\@_'</code>), but those failed with the InvalidURI exception.</p>
<p><strong>TL;DR;</strong></p>
<p>My question is: How do I escape a '@' in the password part of a MongoDB URL?</p> | 0 |
mongodb aggregate with $group and $lookup | <p>I'm trying to perform a "group by" on a table and "join" it with another table.
Corresponding SQL statement would be:</p>
<pre><code>SELECT T1.total, T1.email, T1.type, table_2.name FROM
(SELECT SUM(amount) AS total, email, type
FROM table_1
GROUP BY email, type) T1
INNER JOIN table_2
on T1.email = table_2.email
</code></pre>
<p>But since mongodb still doesn't have inner join feature, I tried to use "$lookup" and do the task. here's my code:</p>
<pre><code>db.table_1.aggregate([
{$group : {_id : {email: "$email", type:"$type"},total: { $sum: "$amount" }}},
{$lookup: {from: "table_2", localField: "email", foreignField: "email", as: "details"}} ]);
</code></pre>
<p>But in the results I'm getting, details returns and empty object:</p>
<pre><code>{ "_id" : { "user" : "[email protected]", "type" : "Car" }, "total" : 2, "details" : [ ] }
{ "_id" : { "user" : "[email protected]", "type" : "Bike" }, "total" : 3, "details" : [ ] }
{ "_id" : { "user" : "[email protected]", "type" : "Car" }, "total" : 1, "details" : [ ] }
</code></pre>
<p>But if I run the query without using $group, it works fine. So I'm wondering whether the $group and $lookup functions cannot be used together. If so is there a work-around or what would be the optimal way to get the query done?</p>
<p>[mongo db version I'm using: > db.version() 3.2.7]</p> | 0 |

<p><strong>npm start</strong> respectively <code>webpack-dev-server --inline --progress --port 3000</code> on the console or in Webstorm →works as expected</p>
<p>When I run <strong>npm build</strong> respectively <code>rimraf dist && webpack --config config/webpack.prod.js --progress --profile --bail</code> it builds the app without errors and the output bundle files get physically placed in the dist folder as expected.</p>

<p>Next I copied the content of the dist folder to the webapps directory of a Tomcat 9.0. When I try to access the installed app I get an 404 error for the .css- and .js-files (<a href="http://i.stack.imgur.com/twslK.png">which can be seen in the attached picture</a>).
It tries to get the files from the wrong URLs →"/obv/" is missing.</p>
<p>I'm really stuck here and I have the feeling that I've tried already everything I could find in the Internet regarding this topic. </p>
<p>Could someone please tell me what I'm doing wrong? Thank you in advance.</p> | 0 |

Does renewing SSL certificate require re-issuing the cert? | <p>I have an SSL certificate that I am using to secure port 443 (HTTPS) on my nginx server running on Ubuntu for about 10 months now.</p>
<p>When I bought the cert, I got it for one year, so I have about 2 more months with this certificate.
My question is: "When I renew this cert, Will I just need to pay for renewal? or will I have to re-issue the cert with a new CSR, and have a potential downtime while installing?</p>
<p>I need to plan for any downtime from now.</p>

Adjusting QML Image display size | <p>I have a QML window with a nested <code>RowLayout</code>. In the inner row I have two images. The source <code>.png</code> files for these images are (intentionally) rather large. When I attempt to set the <code>height</code> property on these images to make them smaller, they are still drawn large.</p>
<p><strong>Desired Appearance</strong>:<br>
<a href="https://i.stack.imgur.com/m8fjF.png" rel="noreferrer"><img src="https://i.stack.imgur.com/m8fjF.png" alt="Two images side-by-side, taking up 1/3 of the window height"></a></p>

<a href="https://i.stack.imgur.com/oiUlf.png" rel="noreferrer"><img src="https://i.stack.imgur.com/oiUlf.png" alt="Two images side-by-side, far larger than their desired size"></a></p>
<p>The only way I have been able to get them to be small is to set the <code>sourceSize.height:100</code> instead of <code>height:100</code>; however, this is not what I want. I want them to be able to scale up and down without reloading.</p>
<p>How can I fix my QML so that the images take on the height of their containing <code>RowLayout</code>?</p>

Storing injector instance for use in components | <p>Before RC5 I was using appref injector as a service locator like this:</p>

});
</code></pre>
<p>ServiceLocator.ts</p>

<p>components:</p>
<pre><code>let myServiceInstance = <MyService>ServiceLocator.injector.get(MyService)

<p>Now doing the same in bootstrapModule().then() doesn't work because components seems to start to execute before the promise. </p>
<p>Is there a way to store the injector instance before components load?</p>
<p>I don't want to use constructor injection because I'm using the injector in a base component which derived by many components and I rather not inject the injector to all of them.</p> | 0 |

XlsxWriter: set_column() with one format for multiple non-continuous columns | <p>I want to write my Pandas dataframe to Excel and apply a format to multiple individual columns (e.g., A and C but not B) using a one-liner as such:</p>
<pre><code>writer = pd.ExcelWriter(filepath, engine='xlsxwriter')
my_format = writer.book.add_format({'num_format': '#'})
writer.sheets['Sheet1'].set_column('A:A,C:C', 15, my_format)
</code></pre>
<p>This results in the following error:</p>
<blockquote>
<p>File ".../python2.7/site-packages/xlsxwriter/worksheet.py", line 114, in column_wrapper</p>
<p>cell_1, cell_2 = [col + '1' for col in args[0].split(':')]
ValueError: too many values to unpack</p>
</blockquote>
<p>It doesn't accept the syntax <code>'A:A,C:C'</code>. Is it even possible to apply the same formatting without calling <code>set_column()</code> for each column?</p> | 0 |
Specify an array of strings as body parameter in swagger API | <p>I would like to post an array of strings like</p>
<pre><code>[
"id1",
"id2"
]

<pre><code>paths:
/some_url:
post:
parameters:
- name: ids
in: body
required: true
</code></pre>
<p>What is the correct way to specify the type of <code>ids</code> as an array of strings?</p>
<p><strong>Update:</strong></p>
<p>According to the specification, the following should work in my option:</p>
<pre><code> parameters:
- in: body
description: xxx
required: true
schema:
type: array
items:
type: string
</code></pre>
<p><a href="https://github.com/Yelp/swagger_spec_validator" rel="noreferrer">https://github.com/Yelp/swagger_spec_validator</a> does not accept it and returns a long list of convoluted errors, which look like the code expects some <code>$ref</code>.</p> | 0 |
Angular 2 HTTP POST does an OPTIONS call | <p>I'm encountering a really strange problem with my Angular 2 application. I actually want to make a POST call containing a JSON to my Play Scala API, but it keeps want to try to make an OPTIONS call.</p>
<p>Here is my code :</p>
<p><strong>LoginService</strong></p>
<pre><code>constructor (private _apiEndpoint: ApiEndpoint) {}
postLogin(login: string, credential: string): Observable<AuthToken> {
let headers = new Headers({ "Content-Type": "application/json" })
let jsonLogin = {"login": login, "password": credential}
return this._apiEndpoint.postLogin(JSON.stringify(jsonLogin), headers)
.map(this._apiEndpoint.extractData)
}
</code></pre>
<p><strong>ApiEndpoint</strong></p>
<pre><code>constructor (private _http: Http) {}
postLogin(body: string, options: any) {
return this._http.post("http://localhost:9000/login", body, {
headers: options
})
}
</code></pre>
<p>And then when I try to make the call (I've tried to console.log to check the JSON and it's correct), and the call tries to make an OPTIONS call for whatever reason :</p>

Jackson JsonNode to typed Collection | <p>What is the proper way to convert a Jackson <code>JsonNode</code> to a java collection?</p>
<p>If it were a json string I could use <code>ObjectMapper.readValue(String, TypeReference)</code> but for a <code>JsonNode</code> the only options are <code>ObjectMapper.treeToValue(TreeNode, Class)</code> which wouldn't give a typed collection, or <code>ObjectMapper.convertValue(Object, JavaType)</code> which feels wrong on account of its accepting any POJO for conversion. </p>
<p>Is there another "correct" way or is it one of these?</p> | 0 |

how to use Run Keyword If with 2 conditions in Robot Framework? | <p>Hi I am using the <a href="http://robotframework.org/robotframework/latest/libraries/BuiltIn.html#Run%20Keyword%20If" rel="nofollow">Run Keyword If</a> in the <a href="http://robotframework.org/robotframework/latest/libraries/BuiltIn.html" rel="nofollow">builtin library</a>, and I want to run a keyword if two conditions are satisfied.
with one condition I was doing it like this:</p>
<pre><code>Scale Down Service Should Succeed
Get Services
:For ${Service} IN @{BODY.json()}
\ Run Keyword If ${Service['DOWN']} Scale Down Service With Correct ID And Can be Scaled Down ${Service['ID']} ${Service['ContainersRunning']}
</code></pre>
<p>now my question is how can I do this with 2 conditions for example ${Service['DOWN']} (type boolean) and ${Service['Name']}="service"</p> | 0 |

Make container accessible only from localhost | <p>I have Docker engine installed on Debian Jessie and I am running there container with nginx in it. My "run" command looks like this:</p>
<pre><code>docker run -p 1234:80 -d -v /var/www/:/usr/share/nginx/html nginx:1.9
</code></pre>
<p>It works fine, problem is that now content of this container is accessible via <code>http://{server_ip}:1234</code>. I want to run multiple containers (domains) on this server so I want to setup reverse proxies for them. </p>
<p>How can I make sure that container will be only accessible via reverse proxy and not directly from <code>IP:port</code>? Eg.:</p>
<pre><code>http://{server_ip}:1234 # not found, connection refused, etc...
http://localhost:1234 # works fine
</code></pre>
<p><strong>//EDIT:</strong> Just to be clear - I am not asking how to setup reverse proxy, but how to run Docker container to be accessible only from localhost.</p> | 0 |

Jenkins groovy pipeline - retrieve build number of built job | <p>I have a pipeline my team is using to spin up cloud VM's and deploy a software stack to them. Part of this process is to bundle up the artifacts from the builds they select. Right now im just grabbing last success of the jobs listed but ive encountered issues of that job being built again in another process before the pipeline can create its bundle, making the bundle grab an artifact built with the wrong dependencies. </p>
<pre><code>def DeployModule(jobName, jobBranch, serverHostName, database){
build job: jobName, parameters: [[$class: 'StringParameterValue', name: 'Branch', value: jobBranch], [$class: 'StringParameterValue', name: 'DatabaseAction', value: database], [$class: 'StringParameterValue', name: 'Profile', value: serverHostName]]
println "$jobName Succesfull"
}
</code></pre>
<p>Is there any way to alter my simple build job method to pull out the actual build number that was triggered? The pipeline console prints what build number is created im just not sure how to get it in my groovy code.</p>

How to stop http.ListenAndServe() | <p>I am using the Mux library from Gorilla Web Toolkit along with the bundled Go http server.</p>

<p>When I call <code>http.ListenAndServe(fmt.Sprintf(":%d", service.Port()), service.router)</code> it blocks and I cannot seem to stop the server from running.</p>
<p>I am aware this has been a problem in the past, is that still the case? Are there any new solutions?</p> | 0 |
Load file with environment variables Jenkins Pipeline | <p>I am doing a simple pipeline:</p>
<p><em>Build -> Staging -> Production</em></p>
<p>I need different environment variables for staging and production, so i am trying to <em>source</em> variables.</p>
<pre><code>sh 'source $JENKINS_HOME/.envvars/stacktest-staging.sh'
</code></pre>
<p>But it returns <em>Not found</em></p>
<pre><code>[Stack Test] Running shell script
+ source /var/jenkins_home/.envvars/stacktest-staging.sh
/var/jenkins_home/workspace/Stack Test@tmp/durable-bcbe1515/script.sh: 2: /var/jenkins_home/workspace/Stack Test@tmp/durable-bcbe1515/script.sh: source: not found
</code></pre>
<p>The path is right, because i run the same command when i log via ssh, and it works fine.</p>
<p>Here is the pipeline idea:</p>
<pre><code>node {
stage name: 'Build'
// git and gradle build OK
echo 'My build stage'
stage name: 'Staging'
sh 'source $JENKINS_HOME/.envvars/stacktest-staging.sh' // PROBLEM HERE
echo '$DB_URL' // Expects http://production_url/my_db
sh 'gradle flywayMigrate' // To staging
input message: "Does Staging server look good?"
stage name: 'Production'
sh 'source $JENKINS_HOME/.envvars/stacktest-production.sh'
echo '$DB_URL' // Expects http://production_url/my_db
sh 'gradle flywayMigrate' // To production
sh './deploy.sh'
}
</code></pre>
<p>What should i do?</p>
<ul>
<li>I was thinking about not using pipeline (but i will not be able to use my Jenkinsfile).</li>
<li>Or make different jobs for staging and production, using EnvInject Plugin (But i lose my stage view)</li>
<li>Or make withEnv (but the code gets big, because today i am working with 12 env vars)</li>

How does 1 left shift by 31 (1 << 31) work to get maximum int value? Here are my thoughts and some explanations I found online | <p>I'm fairly new to bit manipulation and I'm trying to figure out how (1 << 31) - 1 works.</p>
<p>First I know that 1 << 31 is </p>
<pre><code>1000000000000000000000000000
</code></pre>
<p>and I know it's actually complement of minimum int value, but when I tried to figure out (1 << 31) - 1, I found an explanation states that, it's just </p>
<pre><code>10000000000000000000000000000000 - 1 = 01111111111111111111111111111111
</code></pre>
<p>I was almost tempted to believe it since it's really straightforward. But is this what really happening? If it's not, why it happens to be right?</p>
<p>My original thought was that, the real process should be: the two's complement of -1 is</p>
<pre><code>11111111111111111111111111111111
</code></pre>
<p>then (1 << 31) - 1 =</p>
<pre><code>(1)01111111111111111111111111111111
</code></pre>
<p>the leftmost 1 is abandoned, then we have maximum value of int.</p>
<p>I'm really confused about which one is right.</p> | 0 |

Start Confluent Schema Registry in windows | <p>I have windows environment and my own set of kafka and zookeeper running. To use custom objects, I started to use Avro. But I needed to get the registry started. Downloaded Confluent platform and ran this:</p>
<pre><code>$ ./bin/schema-registry-start ./etc/schema-registry/schema-registry.properties
/c/Confluent/confluent-3.0.0-2.11/confluent-3.0.0/bin/schema-registry-run-class: line 103: C:\Program: No such file or directory
</code></pre>
<p>Then I see this on the installation page:</p>
<p>"Confluent does not currently support Windows. Windows users can download and use the zip and tar archives, but will have to run the jar files directly rather than use the wrapper scripts in the bin/ directory."</p>
<p>I was wondering how do I go about starting confluent schema registry in Windows environment ?</p>
<p>Looked at contents of scripts and it is difficult to decipher. </p>

Django REST Framework ManyToMany filter multiple values | <p>I have two models, one defining users, the other defining labels on these users. I am using Django REST Framework to create an API. I would like to be able to query users containing at least the label ids 1 and 2.</p>

<code>[(1,2), (1,2,3), (2,3), (1,3)]</code> I want the query to return
<code>[(1,2), (1,2,3)]</code>.</p>
<p>So far, I've managed to query users with a given label (let's say id=1) by doing: <code>/api/users/?labels=1</code>, but I am unable to query users with labels 1 and 2. I've tried <code>/api/users/?labels=1,2</code> or <code>/api/users/?labels=1&labels=2</code> but it returns some invalid users, i.e. users without labels 1 or 2...</p>

<p><a href="https://i.stack.imgur.com/73HO3.png" rel="noreferrer"><img src="https://i.stack.imgur.com/73HO3.png" alt="QtChart axis wrong scaled"></a></p>
<p>Constructor code of my dialog looks like this:</p>
<pre><code>m_series = new QLineSeries;
m_series->setName(name);
auto chart = new QChart;
chart->legend()->setVisible(false);
chart->addSeries(m_series);
m_axisX = new QDateTimeAxis;
//m_axisX->setFormat("HH:mm:ss");
m_axisX->setTitleText(tr("Zeitpunkt"));
chart->addAxis(m_axisX, Qt::AlignBottom);
m_series->attachAxis(m_axisX);
auto axisY = new QValueAxis;
axisY->setTitleText(unit);
chart->addAxis(axisY, Qt::AlignLeft);
m_series->attachAxis(axisY);
auto chartView = new QChartView(chart, this);
chartView->setRenderHint(QPainter::Antialiasing);
</code></pre>
<p>My MainWindow emits signals containg new values. Multiple opened chart dialogs are connected to that signal.</p>
<pre><code>void ChartDialog::liveUpdate(const RealTimeMeasureRegisters &registers)
{
auto result = ((&registers)->*m_methodPtr)();
m_series->append(registers.timestamp(), result);
}
</code></pre>
<p><strong>Is there some easy way to tell QDateTimeAxis (in my case <code>m_axisX</code>) to automatically adjust to the new values?</strong></p>
<p><a href="https://doc.qt.io/qt-5/qdatetimeaxis.html#setRange" rel="noreferrer">QDateTimeAxis::setRange()</a> does not look good, because I need to set a minimum and maximum.</p> | 0 |

Spring Boot Too Many Redirects | <p>I'm developing a simple login Form using a Thymeleaf & Spring Boot. When i try hitting the following URL in Chrome: "<a href="http://localhost:8080/login" rel="noreferrer">http://localhost:8080/login</a>" i get an error saying "ERR_TOO_MANY_REDIRECTS". I've tried clearing my cache & cookies in the browser and still get the same error.</p>
<p>I tried disabling the default security login screen by putting the following property into my application.properties: <code>security.basic.enabled=false</code></p>
<p>and added the following configuration to my SecurityConfig so any URL except "/login" and "/resources" would get authenticated:</p>
<pre><code>@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserRepository userRepository;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/resources/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.permitAll();
}
</code></pre>
<p>My LoginController is strightforward: </p>
<pre><code>@Controller
public class LoginController {
@RequestMapping(value="/login", method=RequestMethod.GET)
public String loadForm(Model model) {
model.addAttribute("user", new User());
return "redirect:/login";
}
</code></pre>
<p>Anyone have any idea's why this happens?</p> | 0 |

Override a single @Configuration class on every spring boot @Test | <p>On my spring boot application I want to override just one of my <code>@Configuration</code> classes with a test configuration (in particular my <code>@EnableAuthorizationServer</code> <code>@Configuration</code> class), on all of my tests.</p>
<p>So far after an overview of <a href="http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html" rel="noreferrer">spring boot testing features</a> and <a href="http://docs.spring.io/spring/docs/current/spring-framework-reference/html/integration-testing.html" rel="noreferrer">spring integration testing features</a> no straightforward solution has surfaced:</p>
<ul>
<li><code>@TestConfiguration</code>: It's for extending, not overriding;</li>
<li><code>@ContextConfiguration(classes=…)</code> and <code>@SpringApplicationConfiguration(classes =…)</code> let me override the whole config, not just the one class;</li>
<li>An inner <code>@Configuration</code> class inside a <code>@Test</code> is suggested to override the default configuration, but no example is provided;</li>
</ul>
<p>Any suggestions?</p> | 0 |
LazyInitializationException in Hibernate : could not initialize proxy - no Session | <p>I call dao from my service as </p>
<pre><code>@Override
@Transactional
public Product getProductById(int id) {
return productDao.getProductById(id);
}
</code></pre>
<p>and in the dao I am getting product as </p>
<pre><code>@Override
public Product getProductById(int id) {
Product p = sessionFactory.getCurrentSession().load(Product.class, id);
System.out.print(p);
return p;
}
</code></pre>
<p>This runs fine but if I change my dao class to</p>
<pre><code>@Override
public Product getProductById(int id) {
return sessionFactory.getCurrentSession().load(Product.class, id);
}
</code></pre>
<p>I get org.hibernate.LazyInitializationException: could not initialize proxy - no Session. The exception occurs in view layer where I am just printing the product. I do not understand why returning in same line in dao method results in exception in view layer but works fine if I save it in a reference and then return that.</p> | 0 |
Jenkins Setup Wizard Blank Page | <p>I have just installed Jenkins on my RHEL 6.0 server via npm:</p>
<pre><code>npm -ivh jenkins-2.7.2-1.1.noarch.rpm
</code></pre>
<p>I have also configured my port to be 9917 to avoid clashing with my Tomcat server, allowing me to access the Jenkins page at <code>ipaddress:9917</code>. After entering the initial admin password at the <strong>Unlock Jenkins</strong> page, I am presented with a blank page, with the header "SetupWizard [Jenkins]".</p>
<p>Anyone knows why am I getting a blank page, and how do I solve it?</p> | 0 |
In TensorFlow, how can I get nonzero values and their indices from a tensor with python? | <p>I want to do something like this.<br>
Let's say we have a tensor A. </p>
<pre><code>A = [[1,0],[0,4]]
</code></pre>
<p>And I want to get nonzero values and their indices from it. </p>
<pre><code>Nonzero values: [1,4]
Nonzero indices: [[0,0],[1,1]]
</code></pre>
<p>There are similar operations in Numpy.<br>
<code>np.flatnonzero(A)</code> return indices that are non-zero in the flattened A.<br>
<code>x.ravel()[np.flatnonzero(x)]</code> extract elements according to non-zero indices.<br>
Here's <a href="http://docs.scipy.org/doc/numpy-1.10.1/reference/generated/numpy.flatnonzero.html" rel="noreferrer">a link</a> for these operations.</p>
<p>How can I do somthing like above Numpy operations in Tensorflow with python?<br>
(Whether a matrix is flattened or not doesn't really matter.)</p> | 0 |
Terminate all dialogs and exit conversation in MS Bot Framework when the user types "exit", "quit" etc | <p>I can't figure out how to do the a very simple thing in MS Bot Framework: allow the user to break out of any conversation, leave the current dialogs and return to the main menu by typing "quit", "exit" or "start over". </p>
<p>Here's the way my main conversation is set up:</p>
<pre><code> public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
try
{
if (activity.Type == ActivityTypes.Message)
{
UserActivityLogger.LogUserBehaviour(activity);
if (activity.Text.ToLower() == "start over")
{
//Do something here, but I don't have the IDialogContext here!
}
BotUtils.SendTyping(activity); //send "typing" indicator upon each message received
await Conversation.SendAsync(activity, () => new RootDialog());
}
else
{
HandleSystemMessage(activity);
}
}
</code></pre>
<p>I know how to terminate a dialog with <code>context.Done<DialogType>(this);</code>, but in this method, I do not have access to the IDialogContext object, so I cannot call <code>.Done()</code>. </p>
<p>Is there any other way to terminate the whole dialog stack when the user types a certain message, other than adding a check for that in each step of all dialogs?</p>
<p><strong>Posted bounty:</strong></p>
<p>I need a way to terminate all <code>IDialog</code>s without using the outrageous hack that I've posted here (which deletes all user data, which I need, e.g. user settings and preferences). </p>
<p>Basically, when the user types "quit" or "exit", I need to exit whatever <code>IDialog</code> is currently in progress and return to the fresh state, as if the user has just initiated a conversation. </p>
<p>I need to be able to do this from <code>MessageController.cs,</code> where I still do not have access to <code>IDialogContext</code>. The only useful data I seem to have there is the <code>Activity</code> object. I will be happy if someone points out to other ways to do that. </p>
<p>Another way to approach this is find some other way to check for the "exit" and "quit" keywords at some other place of the bot, rather than in the Post method.</p>
<p>But it shouldn't be a check that is done at every single step of the <code>IDialog</code>, because that's too much code and not even always possible (when using <code>PromptDialog</code>, I have no access to the text that the user typed). </p>
<p><strong>Two possible ways that I didn't explore:</strong> </p>
<ul>
<li>Instead of terminating all current <code>IDialog</code>s, start a new conversation
with the user (new <code>ConversationId</code>) </li>
<li>Obtain the <code>IDialogStack</code> object and do something with it to manage the dialog stack.</li>
</ul>
<p>The Microsoft docs are silent on this object so I have no idea how to get it. I do not use the <code>Chain</code> object that allows <code>.Switch()</code> anywhere in the bot, but if you think it can be rewritten to use it, it can be one of the ways to solve this too. However, I haven't found how to do branching between various types of dialogs (<code>FormFlow</code> and the ordinary <code>IDialog</code>) which in turn call their own child dialogs etc.</p> | 0 |

Mongorestore in a Dockerfile | <p>I want to create a Docker image that starts a mongo server and automatically restores from a previous <code>mongodump</code> on startup.</p>

<p>When I run this, I run into this error:</p>

Connect R to a SQL Server database engine | <p>At my work I have R-Studio (Microsoft R Open 3.2.5) installed and would like to connect to a Microsoft SQL Server database, to run scripts using the tables I have. </p>
<p>Is there any chance that I can connect to a SQL Server database using Pentaho and then using the object Execute R-Script to make an OLAP Cube?
Do I need a package to connect SQL engine?
What would be the steps to perform?</p>
<p>I already have the snowflake arquitectura of the data base. With the fact table and the state tables. But I do not know where to start.</p> | 0 |
SQL Azure Integrated Authentication with a cloud-only Azure Active Directory fails | <p>I have created an Azure tenancy and configured the following: </p>
<p><strong>Azure AD with:</strong></p>
<ul>
<li>A simple custom domain name (less than 15 characters). DNS verified etc. All good.</li>
<li>Users and Admins groups</li>
<li>Users in both groups</li>
<li>A VNET and DNS and IP Addresses</li>
<li>Enabled Device Management</li>
<li>Enabled Domain Services and connected to the VNET</li>
</ul>
<p><em>Note that there is nothing on premise, this is all in the cloud. My physical laptop is effectively being used just as a jump box.</em> </p>
<p><strong>A SQL Azure database and server with:</strong></p>
<ul>
<li>Firewall rules open for all necessary incoming connections</li>
<li>An Active Directory admin set as the Admins group I created in Azure AD</li>
<li>The AD users all created in SQL Azure using CREATE USER FROM EXTERNAL PROVIDER;</li>
</ul>
<p><em>I can connect fine to the SQL Azure database from SSMS on my laptop using either Active Directory Universal Authentication or Active Directory Password Authentication. For both of these I get challenged for the username and password as would be expected.</em></p>
<p><strong>Objective:</strong>
I want to be able to use integrated authentication so that can seamlessly flow identity from a) A machine, b) A ASP.NET MVC site. I have not tried Scenario b yes, so let's park that. For scenario a, I have done the following. </p>
<p>Configured an Azure VM:</p>
<ul>
<li>Standard D2 - Windows 10 fully patched</li>
<li>Connected to the same VNET as the domain</li>
<li>SQL Server Management Server 2016 (SSMS) installed (latest and patched - 13.0.15700.28)</li>
<li>ODBC 13.1 installed (though I think this is not relevant)</li>
<li>ADAL</li>
<li>Microsoft Online Services Sign-In Assistant for IT Professionals RTW</li>
</ul>
<p><em>In short, my full "environment" consists of an Azure AD, A SQL Azure DB and a client VM.</em> </p>
<p><strong>Problem:</strong>
I join the VM to my Azure Active Directory using Directory Services, sign out and log in as a valid domain user (valid in AD and SQL Azure with appropriate logins and permissions). When I open SSMS I can connect fine with Active Directory Universal Authentication or Active Directory Password Authentication but when I try connect with Active Directory Authenticated Security, I get the error below. This also happens if I join the VM directly to Azure AD. My deployment is 100% cloud, so there is no federation in place. </p>
<p>So I have two questions: </p>
<ul>
<li>Am I missing something in my configuration or approach or is there a work around? <a href="https://connect.microsoft.com/SQLServer/feedback/details/3101098/active-directory-integrated-authentication-add-support-for-aad-ds-joined-vms" rel="nofollow">It may be an existing issue - see here</a></li>
<li>Would this connectivity (pass through) work if coded in .net 4.6.2 with C# and deployed in the cloud? Possibly with the ODBC 13.1 driver?</li>
</ul>
<p>Thanks</p>

Get and Set class of an element in AngularJs | <p>I've added the ng-click to my icon like this:</p>

How to Set & Get in angular2-localstorage? | <p>From this <a href="https://github.com/marcj/angular2-localstorage" rel="nofollow noreferrer">repo</a>, I've successfully configured this:</p>
<pre><code>import {Component} from "angular2/core";
import {LocalStorageService} from "angular2-localstorage/LocalStorageEmitter";
@Component({
provider: [LocalStorageService]
})
export class AppRoot{
constructor(private storageService: LocalStorageService){}
...
}
</code></pre>
<p>How can I use storageService to set or get in local storage? I can't find example anywhere even in the doc. </p>
<h2>Updated</h2>
<p>After some testing, I've managed it to get it working with Decorator through WebStorage:</p>
<pre><code>import {LocalStorage, SessionStorage} from "angular2-localstorage/WebStorage";
@Component({})
export class LoginComponent implements OnInit {
@LocalStorage() public username:string = 'hello world';
ngOnInit() {
console.log('username', this.username);
// it prints username hello world
}
}
</code></pre>
<p>However, when I used Chrome Dev to see my localstorage, I see nothing there:
<a href="https://i.stack.imgur.com/5fTD9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5fTD9.png" alt="enter image description here"></a></p>
<p>And In another component, </p>
<pre><code>import {LocalStorage, SessionStorage} from "angular2-localstorage/WebStorage";
@Component({})
export class DashboardComponent implements OnInit {
@LocalStorage() public username:string;
ngOnInit() {
console.log(this.username);
// it prints null
}
}

Get Total Number of Cores from a computer WITHOUT HyperThreading | <p>This is a tough one.</p>
<p>I need to use a command to output the exact number of cores from my servers.</p>
<p>My tests: </p>
<ul>
<li><strong><code>X</code>:</strong> On a Windows server with 4 processors (sockets) and 2 cores each without HT.</li>
<li><strong><code>Y</code>:</strong> On a Windows Server with 2 processors (sockets) and 6 cores each with HT.</li>
</ul>
<p><strong><a href="https://docs.microsoft.com/en-us/windows/desktop/api/sysinfoapi/nf-sysinfoapi-getsysteminfo" rel="noreferrer">GetSystemInfo</a></strong> only gets me the number of processors installed: 4 for X, 2 for Y.</p>
<pre><code>| | X: 8 cores | Y: 12 cores |
| | 4x2 (no HT) | 2x6 (HT) |
|----------------|-------------|-------------|
| Desired output | 8 | 12 |
| GetSystemInfo | 4 | 2 |
</code></pre>
<p><code>%NUMBER_OF_PROCESSORS%</code> is a good one, but it takes HT into account. It tells me 8 for X and 24 for Y (since it has HT, I needed it to show 12 instead).</p>
<pre><code>| | X: 8 cores | Y: 12 cores |
| | 4x2 (no HT) | 2x6 (HT) |
|------------------------|-------------|-------------|
| Desired output | 8 | 12 |
| GetSystemInfo | 4 | 2 |
| %NUMBER_OF_PROCESSORS% | 8 | 24 |
</code></pre>
<p><code>"wmic cpu get NumberOfCores"</code> gets me info for each socket. For example:</p>
<p><strong>X:</strong></p>
<pre><code>>wmic cpu get NumberOfCores
NumberOfCores

difference between int and Integer type in groovy | <p>I have just started learning groovy and I am reading "Groovy in Action".
In this book I came across a statement that <strong>it doesn’t matter whether you declare or cast a variable to be of type int or Integer.Groovy uses the reference type ( Integer ) either way.</strong></p>
<p>So I tried to assign <strong>null</strong> value to a variable with type <strong>int</strong></p>
<pre><code>int a = null
</code></pre>
<p>But it is giving me below exception</p>
<blockquote>
<p>org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'null' with class 'null' to class 'int'. Try 'java.lang.Integer' instead
at Script1.run(Script1.groovy:2)</p>
</blockquote>
<p>Then I tried to assign <strong>null</strong> value to a variable with type <strong>Integer</strong></p>
<pre><code>Integer a = null
</code></pre>
<p>and it is working just fine.</p>
<p>Can anyone help me understand how <code>groovy</code> behaves such way or the reason behind it?</p> | 0 |
How can I create a PNG blob from binary data in a typed array? | <p>I have some binary data that happens to be a PNG. I'd like turn it into a blob, get a URL for the blob and display it as an image (or any places else an image URL is valid like css etc..)</p>
<p>Here's what I tried. First I made a small 8x8 red square with yellow "F" image and used pngcrush to make it smaller</p>
<p>You can see the original 91 byte image displays just fine (it's only 8x8 pixels)</p>
<p><img src="https://greggman.github.io/doodles/assets/tiny-crush.png" alt="91 byte png"></p>
<p>Then, for this sample, I converted that to an JavaScript array, I copy it into a Uint8Array, I make a blob from that and a URL from the blob, assign that to an image but the image does not display.</p>

How to capture value of dropdown widget in bokeh python? | <p>The official documentation of bokeh 0.12.1 in the link give the below code for creating a dropdown. </p>
<p><a href="http://docs.bokeh.org/en/latest/docs/user_guide/interaction/widgets.html#userguide-interaction-widgets" rel="nofollow noreferrer">http://docs.bokeh.org/en/latest/docs/user_guide/interaction/widgets.html#userguide-interaction-widgets</a></p>
<p>But it doesn't clearly mention how to capture the value of the dropdown widget when someone click and selects a value from the dropdown.</p>
<pre><code>from bokeh.io import output_file, show
from bokeh.layouts import widgetbox
from bokeh.models.widgets import Dropdown
output_file("dropdown.html")
menu = [("Item 1", "item_1"), ("Item 2", "item_2"), None, ("Item 3", "item_3")]
dropdown = Dropdown(label="Dropdown button", button_type="warning", menu=menu)
show(widgetbox(dropdown))
</code></pre>
<p><strong>Question</strong></p>
<p>Is see that there are 2 methods called on_click() & on_change() but from the documentation couldn't figure out how to capture the value.
How can we assign the selected value to a new variable?</p>
<p><strong>EDIT</strong></p>
<p>Based on input from @Ascurion i have updated my code as shown below. But when i select a value in dropdown nothing is printed in ipython console in Spyder.
Please advise.</p>
<pre><code> from bokeh.io import output_file, show
from bokeh.layouts import widgetbox
from bokeh.models.widgets import Dropdown
output_file("dropdown.html")
menu = [("Item 1", "item_1"), ("Item 2", "item_2"), None, ("Item 3", "item_3")]
dropdown = Dropdown(label="Dropdown button", button_type="warning", menu=menu)
def function_to_call(attr, old, new):
print dropdown.value
dropdown.on_change('value', function_to_call)
dropdown.on_click(function_to_call)
show(widgetbox(dropdown))

How to create a Grouped TableView with sections programmatically in Swift | <p>I would like to know how to create a grouped/sectioned tableview programmatically. The design I am trying to create is this:</p>
<p><a href="https://i.stack.imgur.com/j6bL6.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/j6bL6.jpg" alt="enter image description here"></a></p>
<p>I want there to be a <code>UIImageView</code> at the top with a 160 height, followed by 3 sections, each with a different number of rows. I will then place static labels in each row and then update their labels with my data.</p>
<p>My code for this VC is as follows:</p>
<pre><code>import UIKit
class SelectedFilmTableViewController: UITableViewController {
var film: Film? {
didSet {
navigationItem.title = film?.Film_Name
}
}
var cellId = "cellId"
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: cellId)
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(cellId, forIndexPath: indexPath) as UITableViewCell
cell.textLabel?.text = film?.Directed_By
cell.detailTextLabel?.text = film?.Film_Poster_Image_URL
return cell
}
}
</code></pre>
<p>I have tried adding the method to state the <code>numberOfSections</code> etc but I don't seem to see them when I build the app. All I see is a normal looking tableview. Am I missing some setup?</p>
<p>Because I am navigating to this VC programmatically, I need to set this up without using the storyboard. </p>
<p>Any help on how to create the look I need above is appreciated, thanks!</p> | 0 |
Fixed height for bootstrap pre-scrollable DIV | <p>In my application I have to display bootsatarp grid for database records. Since the number of records count are large enough to view without full page scrolling I wrap my table with bootstrap pre-scrollable div and it gave me the functionality to scroll the table. However all the time DIV size is half of the browser windows. I tried almost every stack overflow posts and suggestions and simply they not work for me. I also tried to fix this with support of java script and it also failed. </p>
<p>This is my HTML code </p>
<pre><code><div class="col-md-9">
<div class="pre-scrollable">
<table class="table table-bordered table-hover header-fixed" id="sometable">
<thead>
<tr>
<th>EMP_No</th>
<th>Name</th>
<th>Designation</th>
<th>Department</th>
<th>Type</th>
<th>#Days</th>
<th>Start Date</th>
<th>End Date</th>
<th>Half day</th>
<th>Status</th>
</tr>
</thead>
<tbody>
</tbody>
<?php //php code for print the table
?>
</div>
</div>
</code></pre>
<p>I populate above table with the results of PHP code. I have not idea how to set this DIV's height to fixed value or full value of the browser windows.below are the CSS that are use </p>
<pre><code><style>
table {

<p>When checked in postgresql/base/17085 directory, file 281016 does not exist.</p>
<p>Would the issue be resolved if I create file manually by using below commands? or is it a bad approach causing more troubles in future?</p>

if -OR statement with comparison operators not working as expected | <p>I have the following code snippet and I cannot figure out why the <code>if</code> is not working. </p>
<p>The goal is to get some input from the user, and if it is a valid input, carry on. If not, then keep asking until it is a valid entry. </p>
<p>No matter what value I enter on the first question (e.g. wmic), it ALWAYS goes into the <code>do loop</code>. When entering, say wmic, on the second pass, it breaks the do as desired. Invalid entries keep me in the loop until I enter a correct entry.</p>
<pre><code>$query_means = read-host 'Enter one of psinfo, powershell or wmic'
if ($query_means -ne "wmic" -OR $query_means -ne "psinfo" -OR $query_means -ne "powershell")
{
do {
$query_means = read-host 'Invalid entry. Enter one of psinfo, powershell or wmic'
}Until ($query_means -eq "wmic" -OR $query_means -eq "psinfo" -OR $query_means -eq "powershell")
}
</code></pre>
<p>The <code>until</code> comparisons works just fine, breaking when desired.</p> | 0 |
Loop through json using jq to get multiple value | <p>Here is volumes.json :</p>
<pre><code>{
"Volumes": [
{
"AvailabilityZone": "us-east-1a",
"Tags": [
{
"Value": "vol-rescue-system",
"Key": "Name"
}
],
"VolumeId": "vol-00112233",
},
{
"AvailabilityZone": "us-east-1a",
"Tags": [
{
"Value": "vol-rescue-swap",
"Key": "Name"
}
],
"VolumeId": "vol-00112234",
},
{
"AvailabilityZone": "us-east-1a",
"Tags": [
{
"Value": "vol-rescue-storage",
"Key": "Name"
}
],
"VolumeId": "vol-00112235",
}
]
}
</code></pre>
<p>I need to get both the value of <code>VolumeId</code> and <code>Tags.Value</code> to be used as the input to invoke another command. It is easy to get a single value from the json array, but I am not able to extract <strong>multiple value</strong> from it and pass it to another bash command. </p>
<p>I can get a single value using this:</p>
<pre><code>cat volumes.json |jq -r '.Volumes[].VolumeId' |while read v; do another_bash_command $v; done
</code></pre>
<p>but I am not able to get multiple value cause this is wrong:</p>
<pre><code> cat volumes.json |jq -r '.Volumes[].VolumeId, .Volumes[].Tags[].Value' |while read v w; do another_bash_command $v $w; done
</code></pre>
<p>as it will then loop 6 times of the outcome instead of 3.</p>
<p><strong>And</strong>, how do I pass those multiple json value in the loop to a bash array so I can use the value in a better way ? Like <code>VolumeId-> $arr[0][0]</code>, <code>Tags.Value-> $arr[0][1]</code>, <code>AvailabilityZone-> $arr[0][2]</code>...etc. I have searched through SO and the jq docs, and tried <code>readarray</code>, but still not able to find out the solution :( Thanks for any help given. </p> | 0 |

Is there a way to view whitespace in SQL Server Management Studio 2016? | <p>It doesn't look to me like there's any menu option which enables whitespace to be viewed in the text editor.</p>
<p>There's a similar question <a href="https://stackoverflow.com/questions/2760124/is-there-any-way-to-view-whitespace-in-the-query-editor-for-sql-server-managemen" title="Is there any way to view whitespace in the query editor for SQL Server Management Studio Express 2005?">here</a>, however this is referring to SSMS Express 2005 . An answer to this question shows how whitespace viewing can be enabled by editing registry values. However, i don't have that path specified in my registry. (I've checked each dir in the SQL Server registry and can't find a 'Visible Whitespace' entry)</p>
<p>I am using <code>SQL Server Management Studio 2016 (v 13.0.15500.91)</code></p>
<p>Surely there must be a way to achieve this. It's not really required but I would like my settings to match my other versions of SSMS.</p> | 0 |

How can I get the status code from an HTTP error in Axios? | <p>This may seem stupid, but I'm trying to get the error data when a request fails in Axios.</p>

How to toggle between bootstrap button classes onClick? | <p>I am using Bootstrap buttons and would like them to change color when clicked. For example, the button is originally gray (btn-default) and should change to green (btn-success) on click. I would like the button to change back to the default class when clicked again. So far I have created an if statement and added the following code, however it is only changing color once, and will not return to the default class when clicked again.</p>

if (this.class= 'btn-default'){
$('#critical_btn').removeClass('btn-default').addClass('btn-success ');
