returning data from a database aplhabetically : Okay so I've created a database which stores different attributes for a given user. I have implemented an algorithm which takes the username attribute and stores the contents of this attribute and stores it in an array. However for some reason, when printing the array it shows the users in alphabetical order: I want it to return the original order of my database. For context I am using the JDBC API in java which takes mySQL sytax.
I have not implemented an ORDER BY statement, it is just a simple SELECT FROM WHERE statement but it seems to return alphabetically.
public void DisplayUsers() throws SQLException {
String queryCount = "SELECT COUNT(Username) FROM UserInfo";
String query = "SELECT Username FROM UserInfo";
declaringDataBase();
rsObj = statObj.executeQuery(queryCount);
String x = null;
while(rsObj.next()){
x = rsObj.getString(1);
}
int rowNum = Integer.parseInt(x);
rsObj = statObj.executeQuery(query);
String UserArray[] = new String[rowNum];
int counter = 0;
while(rsObj.next()){
String user = rsObj.getString("Username");
UserArray[counter] = user;
System.out.println(UserArray[counter]);
counter++;
}
}
the line *declaringDatabase();* simply calls another method to connect my database to the code. The count statement is taking the number of users under attribute Username and creating an integer to store as the length of the array. But anyway my UserArray[] returns values in alphabetical order? does anybody know why! highly appreciated.

how to prove O(max{ f (n),g(n)}) = O( f (n)+g(n))? : I find a rule about algorithms for analysis.
O(max{f(n),g(n)}) = O(f(n)+g(n))
how to prove it？
I know
max{f(n),g(n)} <= f(n)+g(n) <= 2 * max{f(n),g(n)}
thus
max{f(n),g(n)} is O(f(n)+g(n))
max{f(n),g(n)} is O(max{f(n),g(n)})
f(n)+g(n) is O(max{f(n),g(n)})
then?

How can I remove Description Label in ios-chart? : <p>I am trying to remove <code>Description Label</code> in <code>ios-chart</code> library. You can see it on the image below:</p>
<p><a href="https://i.stack.imgur.com/FWEK1.png" rel="noreferrer"><img src="https://i.stack.imgur.com/FWEK1.png" alt="enter image description here"></a></p>
<p>And I know that, on Android (<code>MPAndroidChart</code> library which is the predecessor of ios-chart), I can do the following:</p>
<pre><code>barchart.setDescription(" ");
</code></pre>
<p>but I am trying to do the same on Swift:</p>
<pre><code>barchart.description = ""
</code></pre>
<p>and I am getting the following error:</p>
<blockquote>
<p>Cannot assign to property: 'description' is immutable</p>
</blockquote>
<p>I have looked on the Internet and here in StackOverflow but could not see anything to remove it. </p>
<p>Is it possible to remove that <code>Description Label</code> on <code>ios-chart</code> library?</p>
<p>Thanks in advance!</p>

How to make Keras use Tensorflow backend in Anaconda? : <p>I have install tensorflow-gpu in my Anaconda environment. They both work well. </p>
<p>Now I am trying to install Keras with Tensorflow backend. According to the <a href="https://keras.io/#installation" rel="noreferrer">instruction</a> I just run:</p>
<pre><code>pip install keras
</code></pre>
<p>But it doesn't install keras, then I tried:</p>
<pre><code>conda install -c conda-forge keras=2.0.2
</code></pre>
<p>Then I am now able import keras in python. But the problem is, it always use the Theano backend. I am trying to change this, but not knowing how to do it.</p>
<p>I also tried edit the file <strong>~/.keras</strong>, but actually default backend was tensorflow already.</p>
<p>Please help.. Thank you so much!</p>

<p>The first one uses SingleOrDefault at the end, with Where after the child object, and the second one doesn't use Where.

Split Access database in separat files : I want to export each table of one database in separt accdb-files and I don't get it.
With the following code -> https://www.devhut.net/2012/09/27/ms-access-vba-export-database-objects-to-another-database/ the destination database must already exist.
How can I create e.g. for table1 the file table1.accdb and export only one table in to this database. If the main database has 10 table 10 files should be created and the belonging table should exported as well.

Spark SQL: How to consume json data from a REST service as DataFrame : <p>I need to read some JSON data from a web service thats providing REST interfaces to query the data from my SPARK SQL code for analysis. I am able to read a JSON stored in the blob store and use it.</p>
<p>I was wondering what is the best way to read the data from a REST service and use it like a any other <code>DataFrame</code>. </p>
<p>BTW I am using <code>SPARK 1.6 of Linux cluster on HD insight</code> if that helps. Also would appreciate if someone can share any code snippets for the same as I am still very new to SPARK environment.</p>

How do you mock typeorm's getManager using testdouble? : <p>When creating unit tests for <a href="https://github.com/typeorm/typeorm" rel="noreferrer">typeorm</a>, I want to mock my connection to the database so that I can run unit tests without actually ever connecting to the DB (a good thing!)</p>
<p>I see <a href="https://github.com/typeorm/typeorm/issues/171#issuecomment-347724850" rel="noreferrer">places</a> where people have mocked typeorm's repositories using <a href="https://github.com/testdouble/testdouble.js" rel="noreferrer">testdouble</a> (which I am also using), but I am trying to do this with <a href="https://github.com/typeorm/typeorm/blob/master/docs/working-with-entity-manager.md" rel="noreferrer">getManager</a> and am having an issue figuring out how to make it work.</p>
<p>Here's an example. I have a class that, in the constructor, creates an EntityManager by using getManager() for a connection called 'test':</p>
<pre><code>export class TestClass {
constructor() {
const test: EntityManager = getManager('test');
}
}
</code></pre>
<p>Now I want to test that I can simply create this class. Here's a sample (using mocha, chai, and testdouble):</p>
<pre><code>describe('data transformer tests', () => {
it('can create the test class', () => {
// somehow mock getManager here
const testClass: TestClass = new TestClass();
chai.expect(testClass, 'could not create TestClass').to.not.be.null;
});
});
</code></pre>
<p>When I try this, I get this error message from typeorm:</p>
<pre><code>ConnectionNotFoundError: Connection "test" was not found.
</code></pre>
<p>Here are some of the things I've tried to mock getManager:</p>
<pre><code>td.func(getManager)
</code></pre>
<p>same error as above.</p>
<pre><code>td.when(getManager).thenReturn(td.object('EntityMananger'));
</code></pre>
<p>gets the message:</p>
<pre><code>Error: testdouble.js - td.when - No test double invocation call detected for `when()`.
</code></pre>
<p>Any ideas what the magic sauce is here for mocking <code>getManager</code>?</p>

Convert a word document with different but grouped line responses to an excel/csv document? : I'm tried to convert ~4,000 user entries (ex. from a user database in MS word) to a workable excel/csv document. Each entry, if fully completed, would be in the following format:
State
Full Name
Email
Organization
Position
The entries I have are variations of the above format (meaning that not all the fields were entered). The 1st line is almost always the state, every entry has a full name, not all entries have emails, organization listed, or the position.
For instance the first page of data might look like the following (Each entry is separated by a blank line):

Passing sensitive information to cloud functions : <p>Is there an "official" solution for passing sensitive information, such as API keys, to Google Cloud Functions? In particular it would be nice to avoid passing this information as arguments to the function since it will be the same for every invocation. AWS Lambda has a <a href="http://docs.aws.amazon.com/lambda/latest/dg/tutorial-env_console.html" rel="noreferrer">built-in solution</a> using encrypted environment variables for this. Is there some similar approach for Google Cloud Functions?</p>
<p>I could imagine using a cloud storage bucket or cloud datastore for this, but that feels very manual.</p>

Android Auto Google Play Rejection : <p>Google keeps rejecting my app for the following reason:
"During review, we found that if audio is playing on the device while plugging into the Android Auto experience, the music continues to play through the car speakers without user intent. We see this as a driver distraction, and isn't appropriate for Android Auto apps."</p>
<p>I thought I had taken the appropriate steps to resolve this by following the documentation from here: <a href="https://developer.android.com/training/auto/audio/index.html#isconnected">https://developer.android.com/training/auto/audio/index.html#isconnected</a></p>
<p>However, they rejected me again for the same reason.</p>
<p>In my MediaBrowserServiceCompat StreamService class, I've added the following code:</p>
<pre><code>private IntentFilter androidAutoConnectionIntentFilter = new IntentFilter("com.google.android.gms.car.media.STATUS");
private AndroidAutoConnectionStatusReceiver androidAutoConnectionStatusReceiver = new AndroidAutoConnectionStatusReceiver();
</code></pre>
<p>In the onCreate(), I've added:</p>
<pre><code>registerReceiver(androidAutoConnectionStatusReceiver, androidAutoConnectionIntentFilter);
</code></pre>
<p>and added this class to the service as well:</p>
<pre><code>private class AndroidAutoConnectionStatusReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
System.out.println("*** ANDROID AUTO CONNECTED: " + intent);
String status = intent.getStringExtra("media_connection_status");
boolean isConnectedToCar = "media_connected".equals(status);
if (isConnectedToCar) {
// android auto connected so stop playback
Intent stopIntent = new Intent(context, StreamService.class);
stopIntent.setAction(StreamService.ACTION_PLAYER_STOP);
context.startService(stopIntent);
}
}
}
</code></pre>
<p>Any idea how I can update my app to resolve this rejection?</p>

I had knowledge of HTML/CSS from 5 years ago but I recently did a refresh on <a href="http://codecademy.com" rel="nofollow">Codecademy</a>. I also completed the JavaScript course but that only teaches you the basic building blocks that are needed. I decided to start reading a series of books called <em><a href="https://github.com/getify/You-Dont-Know-JS" rel="nofollow">You Don't Know JS</a></em> on GitHub. My question is, should I read the entire series to be able to learn how to work with DOM or should basic knowledge be enough to start going down that path? Thank you!</p>

i have a list of the times- MainBookmarksList
now i expect to have a groups like this
12:00:05,
12:00:10,
12:00:15,
********
12:30:15,
12:30:25
thanks in advance
i tried this :
TimeSpan interval = new TimeSpan(0, 0, 15);
var groupedTimes = from dt in MainBookmarksList
group dt by dt.Ticks / interval.Ticks
into g
select new { Begin = new DateTime(g.Key * interval.Ticks), Values = g.ToList() };
not what i needed

Why do always must to read the last element we write with C unions? : I'm reading some slides on `enum`s and `unions`, and one slide says:
> You must always read the last element you write.
and then there's the following code:
union Value {
int int_value;
float float_value;
char *str_value;
};
int main(int argc, char *argv[]) {
union Value v;
v.str_value = "ciao";
v.int_value = 100;
printf("v = %s\n", v.str_value); /* undefined behavior! */
}
What does it mean that we have always to read the last element we write? Why accessing the field `str_value` of the union `v` is undefined behaviour?

Chrome memory issue - File API + AngularJS : <p>I have a web app that needs to upload large files to Azure BLOB storage. My solution uses HTML5 File API to slice into chunks which are then put as blob blocks, the IDs of the blocks are stored in an array and then the blocks are committed as a blob. </p>
<p>The solution works fine in IE. On 64 bit Chrome I have successfully uploaded 4Gb files but see very heavy memory usage (2Gb+). On 32 bit Chrome the specific chrome process will get to around 500-550Mb and then crash.</p>
<p>I can't see any obvious memory leaks or things I can change to help garbage collection. I store the block IDs in an array so obviously there will be some memory creeep but this shouldn't be massive. It's almost as if the File API is holding the whole file it slices into memory.</p>
<p>It's written as an Angular service called from a controller, I think just the service code is pertinent:</p>
<pre><code>(function() {
'use strict';

Same STL files with different compilers : <p>There are two binary files obtained from the same source file: one compiled with clang++-3.6 and the other one with g++-4.8. In a call to a function from the stl (std::unique, in particular) gdb brings me to the same file: /usr/include/c++/4.8/bits/stl_algo.h.</p>
<p>I expected that the implementations would be different for each compiler though. Do clang and gcc share parts of their C++ implementations?</p>

How to build a comma separated array in python : <p>I have a list of user id's in a list in python
<code>['user1', 'user2' , 'user3',...]</code>

<p>I have tried this so far, </p>
<pre><code>my_list = ['user1', 'user2' , 'user3'
string = "user_id="
var = [string + x for x in my_list]

<p>But what i actually need is something like this</p>
<pre><code>var = "(|(user_id=user1)(user_id=user2)(user_id=user3))"
</code></pre>
<p>and this list goes for many other values.
I am stuck here how to build this value <code>(user_id=user1)(user_id=user2)(user_id=user3)</code> in python.</p>
<p>Can anyone suggest some ideas?</p>

Difference between UTC and GMT : <p>Hi i have few queries regarding the Time zones:</p>
<ol>
<li>Can the time be captured in UTC alone?</li>
<li>Is UTC -6 and GMT -6 the same, and does that mean it is US local time?</li>
<li>Say, I have UTC time as "02-01-2018 00:03" does that mean my US local time is "01-01-2018 18:00"?</li>
</ol>
<p>I have searched on Wikipedia and many related websites but haven't found a relevant explanation </p>

Why is this code NOT returning false? : <p>Referencing this straightforward conversation:
<a href="https://stackoverflow.com/questions/31044/is-there-an-exists-function-for-jquery?rq=1">Is there an "exists" function for jQuery?</a></p>
<p>The following code is seeing a zero but still evaluating to 'true' for the first case. </p>
<p>Here is the console result:</p>
<blockquote>
<p>Found listView: 0 / 14</p>
</blockquote>
<p>The code is in a dialog window...so perhaps it might see the element on the underlying page. But the zero in the log says otherwise...</p>
<p>Really frustrating edge case (or I've just lost my mind). Help appreciated.</p>
<pre><code>if (('#listViewMenu').length) { // We are on taskpane list view
console.log('Found listView: ' + $('#listViewMenu').length + ' / ' + ('#tableViewMenu').length);

}
if (('#tableViewMenu').length) { // We are in dialog window table view
addTable();

Multi-threading C# : I am finding it difficult to make the following code go any faster. Currently it takes a few hours to update :(
Some background information:
The code selects records from a local database, then updates 3 separate databases all on the same server. When updating the 3 other databases, it does them in single updates.
After updating the records in all 3 database, it them updates the local database with a fresh copy of the data.
It's basically updating prices, and saving the old price.
I tried implementing Multi-threading, but could not get it to work :(
Here is my code:
public string ExportPrices(bool _restorePrices = false)
{
System.IO.File.AppendAllText(System.Web.HttpContext.Current.Server.MapPath("~/Logs/PriceUpdateErrorList.txt"), "Error Messages" + Environment.NewLine);
var db = new UniStockContext();
//fetch all databases to export to
IList<AccDatabase> accDBCol = db.AccDatabases.Where(x => (x.Active == true) && (x.Deleted == false)).ToList();
//fetch all inventory list
IList<Domain.Tables.Inventory> inventoryDBCol = db.Inventories.Where(x => (x.Active == true) && (x.Deleted == false)).ToList();
if (inventoryDBCol.Count > 0)
{
//string xmlResult = "<InventoryExportResponse>";
//loop through databases and export
foreach (AccDatabase accDB in accDBCol)
{
//check database type and call appropriate accounting system method
if ((accDB.Type == AccDatabaseType.SageEvolution) && string.IsNullOrEmpty(accDB.EvolutionCommon))
{
//////////////////////////////////////////
//////////////Sage Evolution//////////////
//////////////////////////////////////////
foreach (AccDatabase accDB2 in accDBCol)
{
if ((accDB2.Type == AccDatabaseType.SageEvolution) && !string.IsNullOrEmpty(accDB2.EvolutionCommon))
{
//pass db and common db to export method for Sage Evolution
try
{
if (!string.IsNullOrEmpty(accDB.DBName))
{
inventoryDBCol = _sageInventory.ExportPrices(accDB, accDB2, inventoryDBCol, restorPrices: false);//this call updates 13000 records
}
}
catch (Exception exExportPrices)
{
System.IO.File.AppendAllText(System.Web.HttpContext.Current.Server.MapPath("~/Logs/_sageInventoryExportPricesCallError.txt"), exExportPrices.ToString());
}
break;
}
}
}
}
//end foreach
//return (xmlResult + "</InventoryExportResponse>");
}
UpdatePricesFromInventoryListBulk(_inventoryCollection);//this call will update 40000 records in local DB.
return "Stock prices synched to accounting system!";
}
public void UpdatePricesFromInventoryListBulk(IList<Domain.Tables.Inventory> invList)
{
var db = new UniStockContext();
db.Configuration.AutoDetectChangesEnabled = false;
foreach (var inventory in invList)

Domain.Tables.Inventory _inventory = db.Inventories

Why can't I open a tab with a html-button while being on the chrome web store? : <p>I have got a page in my frontend with different buttons, all buttons, on their own, work perfectly, but if I click the button that opens an extension in the chrome web store and click on another button afterwards, the page doesn't open.</p>
<p>Here is an exmaple of what I am talking about. If you click the buttons without closing the tabs that are opening, the button you click after the chrome web store opens won't have an effect.

Django channels and socket.io-client : <p>I'm trying to use them for the first time and wonder I'm headed to the right direction.</p>
<p>Here are my understandings, </p>
<p>socket.io is a wrapper around websocket, and falls back to sub-optimal solutions when websocket is not available.</p>
<p>Django channels can talk websocket as well.<br>
(I think it converts django as a message queue like system. although this understanding or misunderstanding should affect this question)</p>
<p>So I'm trying to use Django channels on the server and socket.io-client on the client.</p>
<p>socket.io has api which looks like </p>
<p><code>socket.on(type, (payload)=> {})</code></p>
<p>Whereas Django channels has a form of</p>
<p><code>message.reply_channel.send({
"text": json
})
</code></p>
<p>is the "text" <code>type</code> of <code>socket.on(type)</code>?</p>
<p>Can Django channels and socket.io-client talk to each other?</p>

XCODE 11 Broke DateFormatter? : One day, the app worked. The next day I updated to Xcode 11 and now the app crashes with "unexpectedly found nil" on line 27 (when executing line 15) in the picture.
I asked my co-worker who doesn't yet have Xcode 11, and his doesn't crash. we are on the same branch/commit...everything.
Any advice? any way around this? my code should appear in that image link... need 10 rep to post images.

Android live data - observe always fires after config change : <p>I'm currently refactoring my code to include ViewModel with LiveData provided by android.arch library. I have a simple activity that sends request for a password change to server and acts according to HTTP response code. </p>
<p>For that purpose I have created class that extends ViewModel for data and a repository class to call server. My ViewModel class has one MutableLiveData field which I'm subscribing to from my activity using .observe(...) method. The issue is that code inside .observe(...) fires all the time after configuration changes (i.e. screen rotation) and I have no idea why.</p>
<p>Here is the code of ViewModel, Repository and Activity classes accordingly:</p>
<p>ChangePasswordViewModel</p>
<pre><code>public class ChangePasswordViewModel extends ViewModel{
private MutableLiveData<Integer> responseCode;
private PasswordChangeRepository passwordChangeRepository;
public ChangePasswordViewModel() {
responseCode = new MutableLiveData<>();
passwordChangeRepository = new PasswordChangeRepositoryImpl();
}
public MutableLiveData<Integer> responseCodeLiveData() {
return responseCode;
}
public void sendChangePasswordRequest(String newPassword){
passwordChangeRepository.changePassword(newPassword, passChangeCallback());
}
// Callback that fires after server sends a response
private Callback passChangeCallback(){
...
responseCode.postValue(serverResponse)
...
}
</code></pre>
<p>PasswordChangeRepository</p>
<pre><code>public class PasswordChangeRepositoryImpl {
public void changePassword(String newPassword, Callback<Void> callback){
//Sending new password to server and processing response in callback
ServerCalls.changePassword(newPassword, callback);
}
}
</code></pre>
<p>Activity</p>
<pre><code>public class ChangePasswordActivity extends AppCompatActivity{
...
private void init(){
//Getting appropriate view model
passwordViewModel = ViewModelProviders.of(this).get(ChangePasswordViewModel.class);
// Starting to observe LiveData
passwordViewModel.getResponseCode().observe(this, responseCode -> {
Log.info("Server response is " + responseCode);
});
//Sending new password to server
buttonPassChange.setOnClickListener(view ->
passwordViewModel.sendChangePasswordRequest("newPass")
);
}
...
}
</code></pre>
<p>Problem is that after the first time I send request to server using sendChangePasswordRequest(...) observe code in activity</p>
<pre><code>passwordViewModel.getResponseCode().observe(this, responseCode -> {
Log.info("Server response is " + responseCode);
});
</code></pre>
<p>fires every time after I rotate the screen. Why is that happening? Value of MutableLiveData responseCode hasn't been updated since the last server call, so why does .observe() fires if there were no changes to live data?</p>

Multiple checkboxes to variable logic : <p>I am looking to create a simple page using HTML and (probably) PHP or JQuery. The page should allow for multiple checkbox selection, and give a variable a value based on which boxes are checked. This can be on submit or can render live on the page. </p>
<p>i.e.
<br>Checkbox 1
<br>Checkbox 2
<br>Checkbox 3</p>
<p>If checkbox 1 is checked, variable = X
<br>If checkbox 1 & 2 are checked, variable = Y
<br>If no checkboxes are checked, variable = Z</p>
<p>What is the best way to approach doing this?</p>

why we cannot perform this operation in vector : When we passing vector in function why we cant do it like an array for example.
#include<bits/stdc++.h>
using namespace std;
void func(vector<int> vect)
{
vect.push_back(30);
}
int main()
{
vector<int> vect;
vect.push_back(10);
vect.push_back(20);
func(vect);
for (int i=0; i<vect.size(); i++)
cout << vect[i] << " ";
return 0;
}
In this example, it works fine.
But if I do it like this why it doesn't work like array.
#include<bits/stdc++.h>
using namespace std;
void func(vector<int> *vect)
{
vect.push_back(30);
}
int main()
{
vector<int> vect;
vect.push_back(10);
vect.push_back(20);
func(&vect[0]);
for (int i=0; i<vect.size(); i++)
cout << vect[i] << " ";
return 0;
}
Just like array why this is not possible.

I have created a textbox in html how to get the ansers on that search? : Hi my question is how i put things into the code so if i search for it in the textbox it will show the results from for example wikipedia?
<head></head>
<body>
<form name="test">
<input type=" name=textie">
</form>
</body>
this is the code for the textbox. i use the programm brackets and if i run it it gives me a textbox. if i want to search for something it obviously gives me nothing. it just resets. how do i import the information from wikipedia so it will be shown if i search for it? its kind of like the coding challenge for the wikipedia API (Coding challenge #75) from the coding train.
