Doctrine - How to bind array to the SQL? : <p>My SQL looks something like this:</p>
<pre><code>$sql = "select * from user where id in (:userId) and status = :status";
$em = $this->getEntityManager();
$stmt = $em->getConnection()->prepare($sql);
$stmt->bindValue(':userId', $accounts, \Doctrine\DBAL\Connection::PARAM_INT_ARRAY);
$stmt->bindValue(':status', 'declined');
$stmt->execute();
$result = $stmt->fetchAll();
</code></pre>
<p>But it returns:</p>
<blockquote>
<p>An exception occurred while executing (...) </p>
<p>with params
[[1,2,3,4,5,6,7,8,11,12,13,14], "declined"]</p>
<p>Notice: Array to string conversion</p>
</blockquote>
<p>I cannot user <code>queryBuilder</code> because my real SQL is more complicated (ex. contains joined select, unions and so on)</p>

Why do we need to return state from reducer in React : I am new to Redux and was trying to get how to work with Redux properly but I encountered a confusion on why we need to return state in reducer. Here is the code:
const initialState = {
counter: 0
};
const reducer = (state = initialState, action) => {
if (action.type === "INCREMENT") {
return {
counter: state.counter + 1
};
}
return state; why do we need to use this code?
};
export default reducer;

How to i hide/show user controls in form : <p>I need to change between different displays for my game. I need to show different screens where a player can choose what they want to play and what difficulty they want it. Before user control, I wanted to use panels but, they were really hard to customize because I need to add a lot of picture boxes, so I got myself user controls.<br></p>
<p>Now the problem is that panels were easy to manage with the visible property but, I just can't find the way to make user controls visible and later hide them if a button is clicked.<br></p>
<p>Is there an actual way to change those controls if first, I click the button in the form to make control1 visible, then click the button in control1 to hide control1 and make control2 visible?</p>
<p>the form name is form1 and my current Uc name is UCmilline (info to make it more clear for me cause Im used to video tutorials or live)</p>

Binary operation not working in C : I have 24 bits stored as a string. I'm using C and I want to store each set of 8 bits, starting at position 0, as an element of a u8int_t vector. I've tried different things to no avail. This is my code:
#include <stdio.h>
#include <stdlib.h>
#define SIZE 8
uint8_t send[SIZE/8];
char data[] = "10101010";
printf ("Data is = %s\n", data);
for ( int i = 0; i < SIZE/8; i++)
{
for ( int j = 0; j < 8; j++)
{
send[i] |= (data[j+8*i] == '1') << (7-i);
}
printf("%d\n",send[i]);
}
The value printed is 128, but 10101010 in decimal is 170. Am I missing something?

Must both right-hand expressions of a ternary operator be of compatible types? : <p>My Practice Tests book contains this question on the ternary operator:</p>
<pre><code>// What is the output of the following application?
public class Transportation {
public static String travel(int distance) {
return(distance < 1000 ? "train" : 10);
}
public static void main(String[] args) {
travel(500);
}
}
</code></pre>
<p>It does not compile. The explanation given is the following:</p>
<blockquote>
<p>Ternary operations require both right-hand expressions to be of
compatible data types. In this example, the first right-hand
expression of the outer ternary operation is of type String, while the
second right-hand expression is of type int. Since these data types
are incompatible, the code does not compile, and Option C is the
correct answer.</p>
</blockquote>
<p>Is that really the reason? It looks to me like this example doesn't compile because 10 is not a String and a String is what the method must return.
I'm asking because
<code>System.out.println(distance < 1000 ? "train" : 10);</code>
compiles and runs without a problem.</p>

How to wrap height of Android ViewPager2 to height of current item? : <p>This question is for the new <strong>ViewPager2</strong> class.</p>
<p>There is a <a href="https://stackoverflow.com/questions/34484833/how-to-wrap-the-height-of-a-viewpager-to-the-height-of-its-current-fragment">similar question for the old ViewPager</a>, but the solution requires extending <strong>ViewPager</strong>. However, ViewPager2 is final so cannot be extended.</p>
<p>In my situation, I have a ViewPager2 that contains three different fragments. One of these fragments is much taller than the other two, which means when you swipe to one of the shorter fragments, there is a lot of empty space. So how do I effectively wrap the ViewPager2 to the height of the current fragment?</p>

How to delete ios simulator safari cache : <p>I'm trying to test a website on the iphone simulator, I made some javascript changes and my javascript files are being loaded from cache.</p>
<p>I see the old version files with safari web inspector, resources tab (on simulator window), also the network calls have status 304.
I already disabled cache on macos Safari.
I already tried deleting the safari cache on the simulator settings.
Safari outside the emulator is loading the new files correctly (I emptied/disabled the cache).</p>
<p>I'm using Simulator (10.0 SimulatorAPP-745.10 with iOS 10.3) from XCode on Sierra</p>
<p>How do I delete or disable the simulator cache?</p>

Java - what should be basic stuff is giving errors every line : <p>The objective is to receive in a string of letters and return a string of 1's and 0's that correspond for each. So "100000" for 'a' for example. But it refuses to compile, and I'm unsure what is wrong. The errors are popping up practically every line. I am not sure if I broke some fundamental rule of Java or why it is upset with me. Any direction or tips would be swell.

How to replace the buttons (attachment) only w/ Slack interactive buttons response : <p>I've managed to create a simple interactive button Slack app using a Google Apps Script (GAS). </p>
<p>I know how to replace the original message w/ the response, but I would like to replace only the buttons, as demonstrated (but not clearly explained) multiple places in the Slack Interactive Button documentation:<br>
<a href="https://api.slack.com/docs/message-buttons#crafting_your_message" rel="noreferrer">https://api.slack.com/docs/message-buttons#crafting_your_message</a></p>
<p>I'd like to do what's demonstrated here:
<a href="https://a.slack-edge.com/dcb1/img/api/message_guidelines/Example_6.gif" rel="noreferrer">https://a.slack-edge.com/dcb1/img/api/message_guidelines/Example_6.gif</a></p>
<p>Is this an update of the original message, a replacement of the original message with identical text but different attachment, ...?</p>
<p>My current interactive buttons message code looks like this: </p>
<pre><code>function sendMsgWithButton() {
// slack channel url (where to send the message)
var slackUrl = "https://hooks.slack.com/services/...";
// message text
var messageData = {
"text": "Here's your interactive buttons message.",
"attachments": [
{
"text": "Can you click the button?",
"fallback": "Sorry, no support for buttons.",
"callback_id": "ptNotificationButtonResponse",
"color": "#3AA3E3",
"attachment_type": "default",
"actions": [
{
"name": "userResponse",
"text": "OK",
"style": "primary",
"type": "button",
"value": "ok"
}
]
}
]
}
// format for Slack
var options = {
'method' : 'post',
'contentType': 'application/json',
// Convert the JavaScript object to a JSON string.
'payload' : JSON.stringify(messageData)
};
// post to Slack
UrlFetchApp.fetch(slackUrl, options);
}
</code></pre>
<p>My current action URL code right now looks like this:</p>
<pre><code>function doPost() {
var replyMessage = {"replace_original": true,
"response_type": "in_channel",
"text": "I see you clicked the button."
};
return ContentService.createTextOutput(JSON.stringify(replyMessage)).setMimeType(ContentService.MimeType.JSON);
}
</code></pre>
<p>Instead of replacing the entire original message, I'd like to replace just the buttons with something like a checkbox and confirmation message as demonstrated in the gif above.</p>
<p>Thanks!</p>

How does one detect if one is running within a docker container within Python? : <p>I was trying to find out if my script was running inside a docker container or not within the python script.</p>
<p>Something like:</p>
<pre><code>if inside_docker():
do_stuff()
else:
do_some_other_stuff()
</code></pre>
<p>to do this the only hacky way I found out how to do it is that I can inspect the hostname (with <code>platform.node()</code>) and if the hostname is not the same as my computer then its not in docker (since hostnames docker are some weird hash or something).</p>
<p>Instead I was thinking something a bit more programatic as follows:</p>
<ol>
<li>first detect docker with <code>cat /proc/1/cgroup</code></li>
<li>then compare the name those hierarchies with the docker id/hash.</li>
</ol>
<p>Something like:</p>
<pre><code>from subprocess import call
import platform
hash = call('cat /proc/1/cgroup')
hostname = hostname = platform.node()
docker_boolean = does_hostname_contain_docker_hash(hash, hostname) # true or false
</code></pre>
<p>I thought something like that would work but I can't even get to call the <code>cat /proc/1/cgroup</code> without an error. If I am in docker I get the error:</p>
<pre><code>>>> from subprocess import call
>>> call('from subprocess import call')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/subprocess.py", line 523, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.7/subprocess.py", line 711, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1343, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
</code></pre>
<p>any ideas how to fix that?</p>
<hr>
<p>as a side node I was thinking of making my solution portable but docker is suppose to be portable already so if I am in docker this should always work...</p>

C++ alternative virtual typedef without templates : As many (relatively new?) users of C++, I would like to write
virtual typedef something my_virtual_type;
inside classes definitions.
The most popular alternative seems to be templates, as for instance in http://stackoverflow.com/questions/14741442/alternative-to-virtual-typedef which provides a nice sum up.
However I am not sure it covers everything a virtual typedef would. I present below a problem, for which I would like to have virtual typedefs. I have a (temporary?) working solution using overloading and not templates.
I want to create a fancy tree structure, including iterators.
1) I define a `NodeIndex` type, ancestor of my future iterators. (`NodeIndex` is in my case `std::vector<unsigned int>`, but it doesn't matter.)
2) I define an abstract `BaseTree` class, used in my iterators bellow. The class includes in particular virtual methods which returns `NodeIndex` indexes to move in the tree (e.g. `NodeIndex begin()`), and `operator[](NodeIndex const&)`.
3) I define a `TreeBasicIterator` class, inheriting from `NodeIndex`, which for coherence purpose includes a const reference to a `BaseTree`, and implements various iterators methods (making use of the virtual methods provided by `BaseTree`).
(I have actually two classes: `TreeBasicIterator`, and `Const_TreeBasicIterator` with a const reference to a `const BaseTree`; I use preprocessor macros to mimic a template based on const-ness, but this is another problem.)
4) I have defined a `TreeNode<T>` template class (`T` is the node content), inheriting from `BaseTree`. For now its `begin()` method returns a `NodeIndex`, and its `operator[]` takes a `NodeIndex` as argument, and everything works fine.
5) However I want to include my `TreeBasicIterator` in my `TreeNode` class. I would like to include a
virtual typedef NodeIndex Iterator;
in my `BaseTree` class, and modify the virtual `begin()` method signature to `Iterator begin()`.
Then `TreeNode` would include a
virtual typedef TreeBasicIterator Iterator;
its `begin()` method signature would be `Iterator begin()`,
and everything would be hopefully fine :)
6) I do not wish to use templates on `TreeBasicIterator`: it is now compiled once for all.
Making `BaseTree` a template would make `TreeBasicIterator` a template, and so loose a part of the benefits of the abstraction in `BaseTree`.
Instanciating `BaseTree` with `NodeIndex` as `Iterator` type would be superfluous: in practice nobody would inherit from that particular instance.
7) Prospective:
I will use trees with a fixed or rarely modified structure, but more frequently modified node contents, and even much more frequently read accesses. To optimize access, I intend to further derive from `TreeNode` a `TreeVector` class, which will include a sorted exhaustive `std::vector` of `NodeIndex` (or `BasicTreeIterator`?) indexes. The `Iterator` virtual type in `TreeVector` would be std::iterator.
8) Current (temporary?) working solution:
`TreeNode` defines (via a usual `typedef`) an `Iterator` type (my `TreeBasicIterator` class). It does not override an `Iterator` type from `BaseTree`, but it could.
`BaseTree` has a `NodeIndex begin() const` method, which is both un-hidden, and overloaded in `TreeNode` by a `Iterator begin() const` method.
Similarly, I have a `NodeIndex next_index(NodeIndex) const` in `BaseTree`, which is both un-hidden, and overloaded in `TreeNode` by a `Iterator next_index(Iterator) const` method.

filter object_list in django templete : I am new in Django and have some problem:
I create a template with object_list table and run in each object with loop:
but I also need to have filter by substring then when the user will filter the table will updates online.
I attch part from my code .. only the relvant
I debug the code and get the expected querset both in server print to log and in response ajax call but I still need to refresh point_list in some way or to determine the filters inside the templete and not in the server?
Any help???
--------------------------------------------
1. I create view for this filter get the ajax request with substring value
def filters_points(request):
point_list = Point.objects.all()
try:
req = request.GET.get("filterData")
if req:
point_list = Point.objects.filter(onsitePointName__icontains=req)
except AttributeError:
print("failed")
#qs_json = serializers.serialize('json', point_list)
#return HttpResponse(qs_json, content_type='application/json')
return render_to_response('point/point_list_update.html', {'point_list': point_list})
2. in HTML templete:
<input type="text" id="substring">
{% for point in point_list %}
...
<td> {{ point.mangoId }} </td>
<td> {{ point.onsitePointName }} </td>

<p>I want to sort the three arrays based on the indexes:</p>
<pre><code>indexes -> {0,2,5,8}
sources -> {"how", "are", "you", "today"}
targets -> {"I", "am", "fine", "thanks"}

<p>I can create a new class <code>myClass</code> with all three elements:</p>
<pre><code>class myClass {
int x;
String source;
String target;
}

<p>Reassign everything to myClass, then sort <code>myClass</code> using <code>x</code>. However, this would required additional spaces. I am wondering if it is possible to do <code>in place</code> sorting? Thanks!</p>

mysqldump syntax error - password being used as database name : <p>I'm trying to duplicate a MySQL (5.5.64-MariaDB) database on the same server by following this guide: <a href="https://stackoverflow.com/questions/675289/cloning-a-mysql-database-on-the-same-mysql-instance">Cloning a MySQL database on the same MySql instance</a></p>
<p>The accepted answer didn't work so I reviewed the docs over at MySQL and found that the <a href="https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#mysqldump-option-summary" rel="nofollow noreferrer">mysqldump Options</a> used <code>--user</code> and <code>--password</code> instead of the <code>-u</code> and <code>-p</code> flags on the linked post.</p>
<p>When I execute this:</p>
<pre><code>mysqldump --user myUser --password myPassword dev_db | mysql -umyUser -pmyPassword staging_db
</code></pre>
<p>It firstly asks me to enter a password:</p>
<blockquote>
<p>Enter password: </p>
</blockquote>
<p>So I enter <code>myPassword</code> although unsure why as it's given in the arguments list.</p>
<p>Then it gives the following error:</p>
<blockquote>
<p>mysqldump: Got error: 1049: "Unknown database 'myPassword'" when selecting the database</p>
</blockquote>
<p>If I try entering the <code>--username</code> and <code>--password</code> <em>without spaces</em>:</p>
<pre><code>mysqldump --usermyUser --passwordmyPassword dev_db | mysql -umyUser -pmyPassword staging_db
</code></pre>
<p>It errors</p>
<blockquote>
<p>mysqldump: unknown option '--usermyUser'</p>
</blockquote>
<p>The intention of this is to copy <code>dev_db</code> into a database called <code>staging_db</code>. Both of these databases exist on the same server. The username/password I'm using has full access to every database on the MySQL instance.</p>
<p>Why doesn't this work?</p>
<p>If I use:</p>
<pre><code>$ mysql -umyUser -pmyPassword
</code></pre>
<p>It connects without any issue and gives me the MariaDB command prompt.</p>
<p>Server is running CentOS Linux release 7.7.1908 (Core) </p>
<p>Database version:</p>
<pre><code>$ mysql -V
mysql Ver 15.1 Distrib 5.5.64-MariaDB, for Linux (x86_64) using readline 5.1

Strange behaviour (for me) with ifPresentOrElse of an Optional. (JAVA8) : I have the following code:
Optional<Person> oldestPerson = personenListe.stream().collect(Collectors.reducing(maxAge));
Consumer<Person> personPrinter = p -> System.out.println("The oldest is : " + p.getName());
Runnable noPersonMessagePrinter = () -> System.out.println("There is no person");
oldestPerson.ifPresentOrElse(personPrinter,noPersonMessagePrinter );
My IDE underlines ifPresentOrElse as red, because it doesn't find the signiture, but from my view it should be correct.
Any guess ?

Why is my asynchronous writeFile method behaving sychronously? : I have a simple .js file that reads a text file and the writes it and reads the changed file. For learning purposes, I have implemented the below code. When the control reaches writeFile, shouldn't it be running in the background and the control should go to the console.log("Test") line and then back to the writeFile ? But it actually fully exceutes the writeFile and control goes to the log line which is basically a synchronous behaviour. Am I missing something here ?
`console.log("Begin")
var fs = require("fs");
fs.readFile("input.txt", function(err, data){ if(err){ console.log(err);
} else{ console.log("Inside Read " + data.toString()); fs.writeFile("input.txt", "Replaced Text" , function(err){ if(err){ console.log(err); } else{ console.log("Inside Write"); var data = fs.readFileSync("Input.txt") console.log(data + " is the replaced text"); } console.log("Test2"); } ); }
}
);
console.log("Ended");`

Object.assign—override nested property : <p>I have an Object <code>a</code> like that:</p>
<pre><code>const a = {

…
groups: […]

<p>whereby there are a lot more properties in <code>a.user</code></p>
<p>And I would like to change only the <code>a.user.groups</code> value. If I do this:</p>
<pre><code>const b = Object.assign({}, a, {
user: {
groups: {}
}
});
</code></pre>
<p><code>b</code> doesn't have any other Property except <code>b.user.groups</code>, all others are deleted. Is there any ES6 way to only change the nested property, without loosing all the other, with <code>Object.assign</code>?</p>

Why have to use value.length? : <p>guys.....Please help!!!</p>
<p><a href="https://i.stack.imgur.com/ZFaRN.png" rel="nofollow noreferrer">This is the picture of a textbook page that I'm reading</a></p>
<p>So I'm reading this textbook which is totally horrible, they just give codes out without any explanation.....And this is my first class in Java, I've never coded in any language before......So like a textbook without explanation just totally....you know....give me a super hard time....</p>
<p>Back to topic, in the picture, there are 2 sets of codes, A and B.....I understand B......But I do not get why in A, it used <code>value.length</code> instead of <code>inputs.length</code>? Isn't the array name in this code is <code>inputs</code>??? Is there any specific reason has to use <code>value.length</code> instead of <code>array name.length</code>???</p>

Python slicing explained : <p>OK I understand the basics, but can someone explain code copied from Greg's answer <a href="https://stackoverflow.com/questions/509211/understanding-pythons-slice-notation">here</a>:</p>
<pre><code>a[1::-1] # the first two items, reversed
a[:-3:-1] # the last two items
a[-3::-1] # everything except the last two items, reversed
</code></pre>
<p>To me the first one reads: slice from 2nd position to end, then reverse it.</p>
<p>The second one is slice from beginning to the -2 position then reverse it.</p>
<p>The third one is slice from -3rd position to end then reverse it.</p>
<p>Obviously I am wrong since they work as suggested, but can you please tell me why?</p>

WHERE clause not working for SQLite Android : I am currently doing an Android application with a SQLite database and I want to create a method that will retrieve all tasks that are associated to one owner, but the application cannot retrieve them but instead return me an exception. How can I solve this?
This is the code for the database:
public class SchedulerDbHelper extends SQLiteOpenHelper {

This is the code for the main fragment running the database:
public class SchedulerFragment extends android.support.v4.app.Fragment {

}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getActivity().setTitle("Scheduler");
taskDb = new SchedulerDbHelper(getActivity());
taskList = taskDb.getAllTaskForUser();
Iterator<Task> i = taskList.iterator();
String[] taskNameArray = new String[taskList.size()];
int index = 0;
FloatingActionButton floatingActionButtonNewTask = getView().findViewById(R.id.floatingActionButtonNewTask);
listViewTaskList = getView().findViewById(R.id.listViewTaskList);
while(i.hasNext()){
Task t = i.next();
taskNameArray[index] = t.getTaskName();
index++;
}
try {
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, taskNameArray);
listViewTaskList.setAdapter(adapter);
} catch (RuntimeException r1) {
}
listViewTaskList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String taskName = adapterView.getItemAtPosition(i).toString();
taskPrimary = taskName;
TaskDetailFragment tdf = new TaskDetailFragment();
FragmentManager manager = getFragmentManager();
manager.beginTransaction().replace(R.id.frameLayoutContent, tdf, tdf.getTag()).commit();
}
});
floatingActionButtonNewTask.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
NewSchedulerFragment nsf = new NewSchedulerFragment();
FragmentManager manager = getFragmentManager();
manager.beginTransaction().replace(R.id.frameLayoutContent, nsf, nsf.getTag()).commit();
}
});
}
}
And this is the exception that I got:
