How to correctly use Scanner to print output stream : <p>I am using Scanner to take in input and print output but ln.nextLine() jumps to next line to scan.</p>
<pre><code> Scanner in = new Scanner(System.in);
System.out.println("ENTER ID: ");
String line = null;
while (in.hasNext()) {
line = in.nextLine();
if (line.toLowerCase().equals("exit")) {
break;
} else {
System.out.println("number entered
"+Integer.parseInt(line));
}
System.out.println("ENTER ID: ");
}
</code></pre>
<p><strong>This produces a output like:</strong><br>
ENTER ID:<br>
78<br>
number entered 78<br>
ENTER ID:<br>
89<br>
number entered 89</p>
<p><strong>Desired output is:</strong><br>
ENTER ID: 78<br>
number entered 78<br>
ENTER ID: 89<br>
number entered 89 </p>
<p>what part of println sequence should I change to achieve this?</p>

Different behavior async/await in almost the same methods : <p>Let's say I have two async methods</p>
<pre><code>public async static Task RunAsync1()
{
await Task.Delay(2000);
await Task.Delay(2000);
}
</code></pre>
<p>and</p>
<pre><code>public async static Task RunAsync2()
{
var t1 = Task.Delay(2000);
var t2 = Task.Delay(2000);
await t1;
await t2;
}
</code></pre>
<p>Then I use it like</p>
<pre><code>public static void M()
{
RunAsync1().GetAwaiter().GetResult();
RunAsync2().GetAwaiter().GetResult();
}
</code></pre>
<p>In a result the <code>RunAsync1</code> will run <strong>4sec</strong> but <code>RunAsync2</code> only <strong>2sec</strong> <br>
Can anybody explain why? Methods are almost the same. What is the difference? </p>

How can I log outside of main Flask module? : <p>I have a Python Flask application, the entry file configures a logger on the app, like so:</p>
<pre><code>app = Flask(__name__)
handler = logging.StreamHandler(sys.stdout)
app.logger.addHandler(handler)
app.logger.setLevel(logging.DEBUG)
</code></pre>
<p>I then do a bunch of logging using </p>
<p><code>app.logger.debug("Log Message")</code></p>
<p>which works fine. However, I have a few API functions like:</p>
<pre><code>@app.route('/api/my-stuff', methods=['GET'])
def get_my_stuff():
db_manager = get_manager()
query = create_query(request.args)
service = Service(db_manager, query)
app.logger.debug("Req: {}".format(request.url))
</code></pre>
<p>What I would like to know is how can I do logging within that <code>Service</code> module/python class. Do I have to pass the app to it? That seems like a bad practice, but I don't know how to get a handle to the app.logger from outside of the main Flask file...</p>

Convert SQL or UTIL DATE to expected format "dd-MMM-yyyy", but not in String value : <p>I have a java util Date object and I need to write it in the format "dd-MMM-yyyy", but not as a String ( it can be sql or util Date, it does not matter ) and I do not understand what I am doing wrong because instead of "Nov" for month, I get "11". The right output is given only when I format to String...</p>
<p>Can anyone help me ? This is what I tried so far and the reason I do not want a String is because I need to use this date as a parameter to run a database query and the field type in sql is Date.</p>
<pre><code> Date currentDate = new Date(Calendar.getInstance().getTimeInMillis()); output value: Thu Nov 14 17:21:44 EET 2019
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MMM-yyyy");
String formattedDate = simpleDateFormat.format(currentDate); output value: 14-Nov-2019

VB.Net calling win32 api on 32 and 64 bit systems : To make an existing managed application with unmanaged 'appendages' 64-bit capable, I decided to rewrite a 32 bit unmanaged VC++ dll as a managed VB.Net class library.
The application must be able to run on any framework from 2.0 up, and the VC++ code I ported was using named pipes, which are supported only from framework 3.5 up.
So I had to resort to reflection, calling windows API functions for everything related to the pipes.
The result works perfectly in 32 bit mode, but in 64 bit, I get all kinds of trouble. The actual behavior may change dramatically with even the least change in source code, just swapping some variable declarations around or moving a simple assignment statement to another location in the code may cause any effect from
- "a barely noticeable hiccup every X hours of running fine",
- "appear to receive some bad data from time to time" (it actually took WireShark and a decent portion of luck to find out that the first byte of a 13-byte packet received on the named pipe was passed as 0x00 to managed code, while it was actually received as 0x02 in the pipe data packet, while the rest of the packet was passed intact)
to
- "crash the entire .Net runtime with an error 0xc0000409 in mscorwks.dll soon as a client tries to connect to the pipe".
If you ask me, the latter points towards something somewhere, probably a pointer or handle, is still being stored or passed to/from Win32 API at 32 bit sizes when running at 64 bit, but I can't figure out what.
It must be in the API declarations, the rest is all managed code, and compiled with options 'strict' and 'explicit' both on.
Can someone have a look at this and see if he can spot something I keep overlooking?
Operation is asynchonous. The actual waits are performed at managed level on an array containing managed as well as unmanaged handles (through SafeWaitHandle wrapping), so events in managed together with unmanaged stuff can be dealt with by the same wait.

Relational DB : is it a bad practice to store data on relationships? : <p>I work for a firm with a relational database. Some of my colleagues once told me that storing data directly on relationships (and not on entities) was a bad pratice. I can't remember why. Can you help me with that ? Do you agree ? What are the risks ?</p>
<p>Many thanks !</p>

how to remove duplicate record from results doing left join in sql : I have three tables User Table,Enquiry table and Activity Table .when I do a inner and LEFT JOIN, I am getting duplicate records because of NULL values.
User Table -1
user_id | user_firstName | user_lastName
1 | Joe | Smith
2 | John | Doe
3 | Robert | Smith
Enquiry Table -2
EnquiryID | CreatedBy| |
1 | 1 |
2 | 1 |
Activiy Table - 3
ActivityID | CreatedBy| AssignedBy| AssignedTO|
1 | 1 | null | null |
2 | 1 | 2 | 3 |
Expected Output of all three combining result is
Enquiry ID | | CreatedBy| AssignedBy| AssignedTO|
1 | Joe | null | null |
2 | Joe | John | Rober |
SQL:
SELECT DISTINCT E.EnquirdID as Enquiry,U.FirstName as CreatedBY ,U1.FirstName as AssignedBY , U2,FirstName as AssignedTO
FROM Enquiry E inner join User U on E.UserID = U.UserID
inner join Activity A on E.Enquiry = A.EnquiryID
Left Join User U1 on A.AssignedBY = U1.UserID
Left Join User U2 on A.AssignedTO = U2.UserID
I am getting duplicate Enquiry record from above query even though using Distinct for EnquiryID
END RESULT: My plan is to use the SQL to select the data and display it in PHP on a website. It's a Enquiry management website. I want to be able to have PHP pull the variables from SQL so I can use them however I feel fit.

Which regular expression should I use to validate weight in VB? : <p>In one of my program's procedures; I want to use a regular expression along with a match statement, to make sure that the user properly input's the weight of an individual into a text box and also to make sure that it is entered in the right format. But I don't know which one to implement and am not very experienced with using the RegEx class in VB.Net.</p>
<p>However, I know that the regex which is used must make sure that the user has entered the information in the following format:</p>
<p><strong><em>123lb or 122223lb or 987LB or 23lB</em></strong></p>
<p>The number of digits used before the 'lb' does not matter but the 'lb' section must be case-insensitive. The RegEx must also look for no other letters apart from "lb".</p>
<p>For instance, some examples that shouldn't be matched:</p>
<ul>
<li>lb123 (The lb has to come after the digits)</li>
<li>ab987 (The only letters that should be matched are lb)</li>
<li>4875638546cder (Here the number of digits are fine, but the letters aren't just lb)</li>
</ul>
<p>Therefore in summary, the regex must:</p>
<ul>
<li>Look for no letters other than 'lb'</li>
<li>Make sure that 'lb' comes after the digits entered by the user</li>
<li>Be case-insensitive</li>
</ul>
<p>Any help would be much appreciated!</p>
<p>Thanks for reading and have a good day!</p>

MockRestServiceServer simulate backend timeout in integration test : <p>I am writing some kind of integration test on my REST controller using MockRestServiceServer to mock backend behaviour.
What I am trying to achieve now is to simulate very slow response from backend which would finally lead to timeout in my application. It seems that it can be implemented with WireMock but at the moment I would like to stick to MockRestServiceServer.</p>
<p>I am creating server like this:</p>
<pre><code>myMock = MockRestServiceServer.createServer(asyncRestTemplate);
</code></pre>
<p>And then I'm mocking my backend behaviour like:</p>
<pre><code>myMock.expect(requestTo("http://myfakeurl.blabla"))
.andExpect(method(HttpMethod.GET))
.andRespond(withSuccess(myJsonResponse, MediaType.APPLICATION_JSON));
</code></pre>
<p>Is it possible to add some kind of a delay or timeout or other kind of latency to the response (or maybe whole mocked server or even my asyncRestTemplate)? Or should I just switch to WireMock or maybe Restito?</p>

<p>So, how would I / should I clone arbitrary Kotlin object? </p>
<p>Should I just use <code>clone()</code> as in Java?</p>

How to QUEUE a new build using VSTS REST API : <p>I have the following script</p>
<pre><code>Param(

# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))
$verb = "POST"
$body = @"
{
"definition": {
"id": 20
}
}
"@
$uri = "https://$($vstsAccount).visualstudio.com/DefaultCollection/$($projectName)/_apis/build/builds?api-version=4.1"
$result = Invoke-RestMethod -Uri $uri -Method $verb -ContentType "application/json" -Body (ConvertTo-Json $body) -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
</code></pre>
<p>However I get this error</p>
<pre><code>Invoke-RestMethod : {"$id":"1","innerException":null,"message":"This request expects an object in the request body, but the supplied data could not be
deserialized.","typeName":"Microsoft.TeamFoundation.Build.WebApi.RequestContentException,

<p>So I tried to queue a build from the browser and see the payload using developer tools:</p>
<pre><code>{"queue":{"id":70},"definition":{"id":20},"project":{"id":"b0e8476e-660a-4254-a100-92ef0ec255e5"},"sourceBranch":"refs/heads/master","sourceVersion":"","reason":1,"demands":[],"parameters":"{\"system.debug\":\"false\"}"}
</code></pre>
<p>So, I replaced that into my script:</p>
<pre><code>$body = @"
{"queue":{"id":70},"definition":{"id":20},"project":{"id":"b0e8476e-660a-4254-a100-92ef0ec255e5"},"sourceBranch":"refs/heads/master","sourceVersion":"","reason":1,"demands":[],"parameters":"{\"system.debug\":\"false\"}"}
"@
</code></pre>
<p>However I keep getting the same error.</p>
<p>The official documentation for this endpoint is here, but its not clear

Swift4 How to check if object not exists in array : I should compare MenuArray array, SavedArray array.
If MenuArray does not contain SavedArray's object, should remove SavedArray's object
so I did.
for i in 0..<savedArr.count {
let savedDic = savedArr[i]
let containIndex = menuArray.index(where: { (dic) -> Bool in
if dic[Keys.KEY_DISPETT_SEQ] as! Int == savedDic[Keys.KEY_DISPETT_SEQ] as! Int {
return true
}else{
return false
}
})
if containIndex == nil {
savedArr.filter({ (dic) -> Bool in
return true
})
}
}
But it's not working.
How can I do? Thank you! | 0debug |
How do I compile using javac in command line this small code snippet : <p>I am learning springframework and I don't want to use any IDE, and I want to work in java in pure command line in bash. I already have downloaded lots of jar I can see them in /root/.m2/repository as well as in /usr/share/maven/ref/repository/ too. The <code>AppConfig.java</code> i want to compile has the below content: </p>
<pre><code>@Configuration
public class AppConfig {
// this is all there is
}
</code></pre>
<p>It compiles fine without the <code>@Configuration</code> annotation. At the top of my head, I know that I need to pull-in the correct jar. To be systematic in future dealings of these things, I want to know how to:</p>
<ul>
<li>Identify the correct jar and location of jar needed for a keyword</li>
</ul>
<p>I accept maven pom.xml way of doing things if needed, but if possible I want to work in the most minimal way.</p>

Android Bottom Sheet smooth expanding, like Google Maps : <p>I want to recreate Bottom Sheet Behavior provided in the Google Maps app:

<br><br>
I have tried using <a href="https://developer.android.com/reference/android/support/design/widget/BottomSheetBehavior.html" rel="noreferrer">BottomSheetBehavior</a> and couple of other 3rd party libs like umano AndroidSlidingUpPanel but the problem I was unable to avoid is they are all snapping the Bottom Sheet in between states (collapsed and expanded).
<br><br>
I would like to have a Bottom Sheet which can be smoothly expanded by sliding up, without it snapping to the closest state but instead to remain where the user stopped with the sliding.</p>
