jqGrid 4.12 border disappearing in all browsers <p><a href="https://staging.transporthub.co.uk/gridtest/jqgrid.htm" rel="nofollow">https://staging.transporthub.co.uk/gridtest/jqgrid.htm</a> </p>
<p>When clicking in the cell to edit the value the border at the right and bottom is disappearing. Is there a css issue?</p>
| <p>First of all, please, don't use old versions of <a href="https://github.com/free-jqgrid/jqGrid" rel="nofollow">free jqGrid</a>. The current version of free jqGrid is 4.13.4. I recommend you to change the URLs to CDN (see <a href="https://github.com/free-jqgrid/jqGrid/wiki/Access-free-jqGrid-from-different-CDNs" rel="nofollow">the wiki</a>).</p>
<p>The reason of your problem is not depend from the choice of the version. Your demo contains the following customization:</p>
<pre class="lang-css prettyprint-override"><code>.ui-state-highlight {
border:none!important; /* !!! it's the origin of your problem */
background:none!important;
}
</code></pre>
<p>which is the origin of your problem. You use cell editing (<code>cellEdit: true</code>), which selects (set <code>ui-state-highlight</code> class) non-editable cells during editing. The usage <code>border:none!important;</code> in the above CSS rule removes the border of the cell. You should remove the CSS rule.</p>

setOnAction within another setOnAction not working for arrays of buttons in Javafx <p>I'm actually not sure about the title because I don't know if that is the real problem.
I'm making this application that the user clicks on a plus or minus button to get a number of people, then for each person there are two more plus and minus buttons to get another number that has to be multiplied by 15 and the result is shown in a TextField.
i don't know why my code is giving me this error:
"Local variable i defined in an enclosing scope must be final or effectively final".
I commented the code where the error is shown.</p>
<p>Any help would be very appreciated.</p>
<p>Thanks very much. </p>

| <p>The error is exactly what it says: i must be final (or effectively final, meaning that compiler must be able to deduce that the variable will never change.</p>
<p>In your case, <code>i</code> changes (between 0 and 10), so it's not "effectively final".</p>
<p>What you want to do is add a variable to hold the current snapshot of <code>i</code> and store it in a final variable; for example on the top of the loop add:</p>
<pre><code>final int snapshot = i;
</code></pre>
<p>If you think about it, this Java behavior is very logical - by the time any of the listeners fire, the loop in question is over, so there is no such thing as <em>current value of i</em>. Instead, there's a <em>snapshot of i value taken during the iteration when the listener was established</em>.</p>

Allow multiple controllers to users according to their role in cakephp <p>Suppose, there are two roles: one is <code>admin</code>, another is <code>restaurant_owner</code>.</p>
<p>I want to give access to some of the pages to <code>restaurant_owner</code>.</p>
<p>In <code>AppController</code>, I used <code>beforeFilter</code> function. Here is the code..</p>
<pre><code>public function beforeFilter() {
if($this->Auth->user('role') == 'restaurant_owner'){
/* Controllers Name, that Admin want to give access to restaurant admin*/
$this->loadModel('Userpermission');
$AuthPermission = $this->Userpermission->find('first',array('conditions' => array('Userpermission.user_id' => $this->Auth->user('id'))));
print_r($AuthPermission); //returns controller names e.g. receipes, menuitems
}
}
</code></pre>
<p>My question is, how I deny access to role <code>restaurant_owner</code> to all controllers except but a few? I'm using CakePHP 2.x.</p>
| <p>The proper way of handling this is through <a href="http://book.cakephp.org/2.0/en/core-libraries/components/authentication.html#using-controllerauthorize" rel="nofollow"><code>ControllerAuthorize</code></a> and the <code>AuthComponent::isAuthorized()</code> callback.</p>
<p>First, you have to enable this functionality in <code>AppController</code>. Edit your <code>Auth</code> config and array and add the following:</p>
<pre><code>public $components = array(
'Auth' => array('authorize' => 'Controller'),
);
</code></pre>
<p>Then add the following to the controllers which <code>restaurant_owner</code> should have access to:</p>
<pre><code>public function isAuthorized($user) {
if ($user['role']=="restaurant_owner") {
return true;
}
return parent::isAuthorized($user);
}
</code></pre>
<p>Finally, add the following to <code>AppController</code>:</p>
<pre><code>public function isAuthorized($user) {
if ($user['role']=="restaurant_owner") {
return false;
}
return true; //Every other role is authorized
}
</code></pre>
<p>You will have to tweak the above logic to match your needs.</p>

How to add object in an array of objects using Javascript <p>I have the below JS object and I need to push another similar object with <code>request.rules[0]</code>.</p>
<pre><code>request : [
rules:
[
{

[
{
matchType: 'contains',
type: 1,
value: 'a'
},
{
matchType: 'does not contain',
type: 1,
value: 'b'
}
],
name: 'TEST'
}
]
]
</code></pre>
<p>This is the object that I need to push to request.rules[1]:</p>
<pre><code>{
pageFilters:
[

},
{
matchType: 'does not contain',
type: 1,
value: 'd'
}
],
name: 'TEST 2'
}
</code></pre>
<p>This is what I've tried to implement, but it does not work ...</p>
<pre><code>request.rules[1].pageFilters[0].push({
matchType: 'contains',
type: 1,

})
request.rules[1].pageFilters[1].push({
matchType: 'contains',
type: 1,

{
matchType: 'does not contain',
type: 1,
value: 'd'
}
],

| <p>You do not have to push to a specific position e.g request.rules[1].pageFilters[0], but rather to the array itself like this</p>
<pre><code>var anotherFilter = {
matchType=contains,
type=1,
value=c
};
request.rules[1].pageFilters.push(anotherFilter);

sessionStorage doesnt work on safari on iphone 6 - non private mode <p>If i use the following code below, it works perfectly on firefox (private window or normal window). I tried to use it on my iphone 6 using safari and it doesnt seem to store my information in normal mode (non private mode)? Maybe the code is not right for safari? Can someone assist me? Thanks!</p>
<p>Code:</p>
<pre><code><script>
// Run on page load
window.onload = function()
{
// If sessionStorage is storing default values (ex. name), exit the function and do not restore data
if (sessionStorage.getItem('name') == "name")
{
return;
}
// If values are not blank, restore them to the fields
var name = sessionStorage.getItem('name');
if (name !== null) $('#playlisthiddenfield').val(name);
}
// Before refreshing the page, save the form data to sessionStorage
window.onbeforeunload = function()
{
sessionStorage.setItem("name", $('#playlisthiddenfield').val());
}
</script>
</code></pre>
<p>Basically the issue is, once i refresh the information in the input field disappears where as in firefox it stays (Which i want it to).</p>
| <p>I dont exactly have the answer to the question but instead i decided to use cookies to complete this task and i am only storing a value which i can access with an if statement so no personal information is stored.</p>

F# Sort an Array with foldBack or fold. <p>I am trying to sort an Array by using fold or foldBack. </p>
<p>I have tried achieving this like this: </p>
<pre><code>let arraySort anArray =
Array.fold (fun acc elem -> if acc >= elem then acc.append elem else elem.append acc) [||] anArray
</code></pre>
<p>this ofcourse errors horribly. If this was a list then i would know how to achieve this through a recursive function but it is not. </p>
<p>So if anyone could enlighten me on how a workable function given to the fold or foldback could look like then i would be createful. </p>
<p>Before you start advising using <code>Array.sort anArray</code> then this wont do since this is a School assignment and therefore not allowed. </p>
| <h3>To answer the question</h3>
<p>We can use <code>Array.fold</code> for a simple insertion sort-like algorithm:</p>
<pre><code>let sort array =
let insert array x =
let lesser, greater = Array.partition (fun y -> y < x) array
[| yield! lesser; yield x; yield! greater |]
Array.fold insert [||] array
</code></pre>
<p>I think this was closest to what you were attempting.</p>
<hr>
<h3>A little exposition</h3>
<p>Your comment that you have to return a sorted version of the same array are a little confusing here - F# is immutable by default, so <code>Array.fold</code> used in this manner will actually create a new array, leaving the original untouched. This is much the same as if you'd converted it to a list, sorted it, then converted back. In F# the array type is immutable, but the elements of an array are all mutable. That means you can do a true in-place sort (for example by the library function <code>Array.sortInPlace</code>), but we don't often do that in F#, in favour of the default <code>Array.sort</code>, which returns a new array.</p>
<p>You have a couple of problems with your attempt, which is why you're getting a few errors.</p>
<p>First, the operation to append an array is very different to what you attempted. We could use the <code>yield</code> syntax to append to an array by <code>[| yield! array ; yield element |]</code>, where we use <code>yield!</code> if it is an array (or in fact, any <code>IEnumerable</code>), and <code>yield</code> if it is a single element.</p>
<p>Second, you can't compare an array type to an element of the array. That's a type error, because <code>compare</code> needs two arguments of the same type, and you're trying to give it a <code>'T</code> and a <code>'T array</code>. They can't be the same type, or it'd be infinite (<code>'T = 'T array</code> so <code>'T array = 'T array array</code> and so on). You need to work out what you should be comparing instead.</p>
<p>Third, even if you could compare the array to an element, you have a logic problem. Your element either goes right at the end, or right at the beginning. What if it is greater than the first element, but less than the last element?</p>
<p>As a final point, you can still use recursion and pattern matching on arrays, it's just not quite as neat as it is on lists because you can't do the classic <code>| head :: tail -></code> trick. Here's a basic (not-so-)quicksort implementation in that vein.</p>
<pre><code>let rec qsort = function
| [||] -> [||]
| arr ->
let pivot = Array.head arr
let less, more = Array.partition (fun x -> x < pivot) (Array.tail arr)
[| yield! qsort less ; yield pivot ; yield! qsort more |]
</code></pre>
<p>The speed here is probably several orders of magnitude slower than <code>Array.sort</code> because we have to create many many arrays while doing it in this manner, which .NET's <code>Array.Sort()</code> method does not.</p>

How to add event to my CustomCell in Swift3 <p>I have a UITableView which has rows which include two UISwitch buttons. Until I upgraded to Xcode8 it worked with me adding a protocol to the view controller like this</p>
<pre><code>protocol CustomCellDelegator {
func callSegueFromCell()
}
</code></pre>
<p>Then I added the following to my CustomCell swift file which handles the outlets for my custom cell.</p>
<pre><code>open class CustomTableViewCell: UITableViewCell {
var delegate:CustomCellDelegator!
@IBOutlet weak var uidLabel: UILabel!
@IBOutlet weak var stateLabel: UILabel!
@IBOutlet weak var operatedSwitch: UISwitch!
@IBOutlet weak var switchRTN: UISwitch!
override open func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
@IBAction func operatedSwitchChange() {
if operatedSwitch.isOn {
AppDelegate.myGlobalVars.gSwitchType = "OpsOn"
}
else {
AppDelegate.myGlobalVars.gSwitchType = "OpsOff"
}
if(self.delegate != nil){ //Just to be safe.
self.delegate.callSegueFromCell()
}
}
@IBAction func rtnSwitchChange() {
if switchRTN.isOn {
AppDelegate.myGlobalVars.gSwitchType = "RtnOn"
}
else {
AppDelegate.myGlobalVars.gSwitchType = "RtnOff"
}
if(self.delegate != nil){ //Just to be safe.
self.delegate.callSegueFromCell()
}
}
}
</code></pre>
<p>Until I upgraded this worked and delegate always had a value, now it is always nil and the segue is never called.</p>
<p>What do i need to do differently since I upgraded to get this working again? </p>
| <p>Make sure You assign your delegate in <code>cellForRowAtIndexPath</code> for the cell.
Also, I would recommend to keep <code>weak</code> reference to the delegate.</p>
<pre><code>protocol CustomCellDelegator: class {
func callSegueFromCell()
}
</code></pre>
<p>In your <code>CustomTableViewCell</code> replace </p>
<pre><code>var delegate:CustomCellDelegator!
</code></pre>
<p>with </p>
<pre><code>weak var delegate: CustomCellDelegator?
</code></pre>
<p>After this you do not need to check if Your delegate is <code>nil</code> or not, your app will not crash.</p>

Scala implicit macros: Filter type members (tpe.decls) by sub-type <p>Let's say I have a simple impicit macro that gives me back a <code>weakTypeSymbol</code>:</p>
<pre><code>@macrocompat.bundle
class ExampleMacro(val c: blackbox.Context) {
def macroImpl[T : WeakTypeTag]: Tree = {
val tpe = weakTypeOf[T]
val subType = typeOf[SomeType].typeSymbol
val target = tpe.decls.collect {
case tp if tp.typeSignature.typeSymbol == subType => tp
}
...
}
}
</code></pre>
<p>That's a very rudimentary version of it, in short I need inner members of <code>T</code> that satisfy a particular sub-typing relationship. It looks like the types on the inner members however have not been evaluated at this time, because <code>tp.typeSignature.typeSymbol</code> is <code><none></code>.</p>
<p>Is there a known way of doing this properly?</p>
| <p>This is doable with an API similar to reflection:</p>
<pre><code> class TestMacro(val c: blackbox.Context) {
import c.universe._
def filterMembers[
T : WeakTypeTag,
Filter : TypeTag
]: List[Symbol] = {
val tpe = weakTypeOf[T].typeSymbol.typeSignature
(for {
baseClass <- tpe.baseClasses.reverse
symbol <- baseClass.typeSignature.members.sorted
if symbol.typeSignature <:< typeOf[Filter]
} yield symbol)(collection.breakOut)
}

Verify private static method on final class gets called using PowerMockito <p>I have the following class</p>
<pre><code>public final class Foo {
private Foo() {}
public static void bar() {
if(baz("a", "b", new Object())) { }
}
private static boolean baz(Object... args) {
return true; // slightly abbreviated logic
}
}
</code></pre>
<p>And this is my Test:</p>
<pre><code>@PrepareOnlyThisForTest(Foo.class)
@RunWith(PowerMockRunner.class)
public class FooTest {
@Test
public void bar() {
PowerMockito.mockStatic(Foo.class); // prepare
Foo.bar(); // execute
verifyPrivate(Foo.class, times(1)).invoke("baz", anyVararg()); // verify - fails
}
}
</code></pre>
<p>For that, I get the following error message - and I don't understand why...</p>
<blockquote>
<p>Wanted but not invoked com.example.Foo.baz(
null );</p>
<p>However, there were other interactions with this mock.</p>
</blockquote>
<p>Removing the <code>prepare</code> line above seems to make the verify line pass no matter for how many <code>times</code> you check for... :(</p>
<p>(Our SONAR code checks enforce that each test has some sort of <code>assertXyz()</code> in it (hence the call to <code>verify()</code>) and enforces a very high test coverage.)</p>
<p>Any ideas how to do this?</p>
| <p>The problem with your code is that you <strong>mock</strong> <code>Foo</code> so your method implementations won't be called by default such that when you call <code>Foo.call()</code> it does nothing by default which means that it never avtually calls <code>baz</code> that is why you get this behavior. If you want to <strong>partially mock</strong> <code>Foo</code>, mock it using the option <code>Mockito.CALLS_REAL_METHODS</code> in order to make it call the real methods as you seem to expect, so the code should be:</p>
<pre><code>@PrepareOnlyThisForTest(Foo.class)
@RunWith(PowerMockRunner.class)
public class FooTest {
@Test
public void bar() throws Exception {
PowerMockito.mockStatic(Foo.class, Mockito.CALLS_REAL_METHODS); // prepare

Regex in Node.js not showing all matches <p>To prepare a request-url for an API-call I am using RegEx to replace values from a String with values from an object. </p>
<p>Example of a 'template-string':</p>
<pre><code>'https://api.fitbit.com/1/user/:ownerId/:collectionType/date/:date.json'
</code></pre>
<p>where :ownerId, :collectionType and :date will be replaced by the values from the following object:</p>
<pre><code>{ collectionType: 'activities',
date: '2016-10-12',
ownerId: 'xxxxx',
ownerType: 'user',
subscriptionId: 'xxx' }
</code></pre>
<p>The regular expression I am using is: </p>
<pre><code>/:([\w]+)/gi
</code></pre>
<p>This allows me to use the content of the group in every match to fetch the value from the object. (the match without the ':' in this case) I have the following function to return the request-url: (url is the 'template-string' and decoded is the object above)</p>
<pre><code>function regexifyUrlTemplate(url, regex, decoded) {
console.log('Regexify URL: ', url)
console.log('Regexify Data: ', decoded)
var m
while (( m = regex.exec(url)) !== null) {
if (m.index === regex.lastIndex) {
regex.lastIndex++
}
console.log('Matches: ', m)
url = String(url).replace(m[0], decoded[m[1]])
console.log('Replaced ' + m[0] + ' with ' + decoded[m[1]])
}
console.log('Regexify :', url)
return url
}
</code></pre>
<p>The console shows me the following logs:</p>
<pre><code>Regexify URL: https://api.fitbit.com/1/user/:ownerId/:collectionType/date/:date.json
Regexify Data: { collectionType: 'activities',
date: '2016-10-12',
ownerId: 'xxx',
ownerType: 'user',
subscriptionId: 'xxx' }
Matches: [ ':ownerId',
'ownerId',
index: 31,
input: '\'https://api.fitbit.com/1/user/:ownerId/:collectionType/date/:date.json\'' ]
Replaced :ownerId with xxx
Matches: [ ':date',
'date',
index: 59,
input: '\'https://api.fitbit.com/1/user/xxx/:collectionType/date/:date.json\'' ]
Replaced :date with 2016-10-12
Regexify : 'https://api.fitbit.com/1/user/xxx/:collectionType/date/2016-10-12.json'
</code></pre>
<p>It successfully replaces :ownerId and :date but does not replace :collectionType. I verified the RegEx at <a href="https://regex101.com" rel="nofollow">regex101.com</a> and went through the regex with the updated strings from the logs. </p>
<p>Can anyone explain why :collectionType is not being matched? The only difference I can spot is the 'T' but with [\w] that should not matter. (also tried [a-zA-Z]). </p>
| <p>The problem was here <code>url = String(url).replace(m[0], decoded[m[1]])</code></p>
<p>You modify <code>url</code> during the <code>exec()</code>, so matche's index change ...</p>

Wordpress PHP shortcode, get_the_content by id won't display custom post type content <p>Currently working on a project where I want to display employees' business cards by a shortcode, for instance <code>[person id="1"]</code> or [<code>person name="bob"]</code>. </p>
<p>I've created a seperate post type for employees, where title=name, content=contact info and thumbnail=image. </p>
<p>The problem is that title and thumbnail shows the right employee data, but <code>get_the_content($post_id)</code> displays the content of my first post "Welcome to ...! This is your first post...".</p>
<pre><code>function display_person($atts, $content){
extract(shortcode_atts(array(
'posts_per_page' => '1',
'post_type' => 'person',
'post_id' => null,
'caller_get_posts' => 1)
, $atts));
global $post;
$posts = new WP_Query($atts);
$output = '';
if ($posts->have_posts())
while ($posts->have_posts()):
$posts->the_post();
$out = '<div class="col-lg-6 col-md-12 col-sm-12 col-xs-12">

</code></pre>
<p>How do I get <code>get_the_content($post_id)</code> to display the custom post content?</p>
| <p>Your code seems a bit faulty.</p>
<pre><code>// this is your shortcode
extract(shortcode_atts(array(
'posts_per_page' => '1',
'post_type' => 'person',
'post_id' => null,
'caller_get_posts' => 1)
, $atts));
</code></pre>
<p>It should look like this (based on the assumption, that $atts' elements are taken from the shortcode parameters):</p>
<pre><code>// you extract the parameters into variable names
extract(shortcode_atts(array(
'posts_per_page' => 'posts_per_page_var',
'post_type' => 'post_type_var',
'post_id' => 'post_id_var',
'caller_get_posts' => 'caller_get_posts_var')
, $atts));
// creating the array of arguments for the query
$new_atts = array(
'posts_per_page' => $posts_per_page_var,
'post_type' => $post_type_var,
'post_id' => $post_id_var,
'caller_get_posts' => $caller_get_posts_var
);
$posts = new WP_Query($new_atts);
// and go on with your code...
</code></pre>
<p>It think this should solve your problem.</p>

Is drag-and-drop to open a file possible in VSCode? <p>I am wondering if something is wrong with my computer (or myself), because I can't seem to drag & drop a file into Visual Studio Code to open it in the editor. Closing an opened folder first doesn't make a difference. VSCode always shows me the 'stop sign', in every spot I tried (the editor, the opened tab bar, an existing opened file, ...).</p>
<p>Why does VSCode block this ?</p>
<p>(I have experienced this in earlier versions as well. Currently on v1.6 on Windows 7.)</p>
| <p>Searching for a solution, I stumbled on <a href="https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/72f35f33-2df0-47e8-a16d-006f1190d81e/drag-and-drop-brokendisabled-when-running-as-an-administrator-?forum=windowsgeneraldevelopmentissues" rel="nofollow">this page</a>, where one commenter explains:</p>
<blockquote>
<p>I think you are running into the security issue where lower permission processes cannot send messages to higher permission processes. Explorere.exe, running at normal permission levels, cannot send the window message to winword.exe, running elevated. </p>
</blockquote>
<p>I am indeed always running VSCode as Administrator, but not my Explorer windows. </p>
<p><strong>When I run VSCode in non-administrator mode (so just my regular user), drag-and-drop works fine.</strong></p>

Unit test Angular 2 error: Bootstrap at least one component before injecting Router? <p>I am writing test for component in angular 2 and I see a problem as below:</p>

Laravel 5.3 - TokenMismatchException in VerifyCsrfToken.php line 68: <p>When I log in to my app, and immediately go back when I enter it, and then try to log out, I get the error from the title, how can I fix that?</p>
| <p>From Laravel 5.3 docs </p>
<blockquote>
<p>The Auth::routes method now registers a POST route for /logout instead of a GET route. This prevents other web applications from logging your users out of your application.

Search values on multidimensional array then display the result <p>I'm trying to retrieve the values on multidimensional arrays using a search like function.</p>
<pre><code>$rows = array(
array(
'Name'=>'City of God',
'Year'=>'2002',
'Rating'=>'10'
),
array(
'Name'=>'The Great Escape',
'Year'=>'1963',
'Rating'=>'9'
),
array(
'Name'=>'Dune',
'Year'=>'1984',
'Rating'=>'6'
),
array(
'Name'=>'Superbabies: Baby Geniuses 2',
'Year'=>'2004',
'Rating'=>'1'
)
);
</code></pre>
<p>So for example, if you want to search the array with a value of Name with 'City of God' and Year with '1963' the expected output should be like this </p>
<pre><code>$rows = array(
array(
'Name'=>'City of God',
'Year'=>'2002',
'Rating'=>'10'
),
array(
'Name'=>'The Great Escape',
'Year'=>'1963',
'Rating'=>'9'
),
);
</code></pre>
<p>Currently, the function I am using is this </p>
<pre><code>function multiSearch(array $array, array $pairs)
{
$found = array();
foreach ($array as $aKey => $aVal) {
$coincidences = 0;
foreach ($pairs as $pKey => $pVal) {
if (array_key_exists($pKey, $aVal) && $aVal[$pKey] == $pVal) {
$coincidences++;
}
}
if ($coincidences == count($pairs)) {
$found[$aKey] = $aVal;
}
}
return $found;
}
</code></pre>
<p>However, using this function only capable of retrieving data of the same array key. So for example if I search the value of Name of 'City of God' </p>
<pre><code>$x = multiSearch($rows, array('Name' => 'City of God')
</code></pre>
<p>This will display the correct output like this </p>
<pre><code>$rows = array(
array(
'Name'=>'City of God',
'Year'=>'2002',
'Rating'=>'10'
),
);
</code></pre>
<p>Unfortunately, if you try to use, 'Name' => 'City of God' and 'Year' => '1963'
It will not display any output. I'm stuck on figuring out on displaying the correct output, any ideas would be appreciated</p>
| <p>try this it is reffered from <a href="http://stackoverflow.com/questions/8881676/how-can-i-check-if-an-array-contains-a-specific-value-in-php">How can I check if an array contains a specific value in php?</a></p>

How to override System.Web.HttpContext.Current.Session (MVC4) <p>I'm trying to override <code>System.Web.HttpContext.Current.Session["foo"]</code>.</p>
<p>My problem is that the system is already using <code>System.Web.HttpContext.Current.Session</code> and I want to add a guid on every session name. (too many to replace)</p>
<p>e.g, <code>System.Web.HttpContext.Current.Session[guid + "foo"]</code></p>
<p>Is it possible for me to override the <code>get</code> and <code>set</code> property?</p>
| <p>If you do not want to use an extension method and change all the already implemented code that calls the string indexer then you could roll your own provider and do it there. See <a href="https://msdn.microsoft.com/en-us/library/ms178587.aspx" rel="nofollow">Implementing a Session-State Store Provider</a>. You can then implement your "guid prefix" there.</p>
<p>Here is an example of an extension method. I have no idea where you are getting <code>guid</code> from, you never mentioned this but you can take this example and add it yourself.</p>
<pre><code>public static class HttpSessionStateExtension
{
public static object Get(this System.Web.SessionState.HttpSessionState session, string key)
{
var guid = ???; // no idea where or how you are getting guid, you never explained that in your question
return session[guid + key];
}
}
// in other methods you can then call it the same as you would the indexer
var result = System.Web.HttpContext.Current.Session.Get("foo");

c# EF query explosion <p>Dealing with three tables - Company, Employee and User. </p>
<p>Company has 0 or Many Employees.
Employee has a nullable int FK to Company. In practice this alway has a value.
Employee has a non nullable int FK to User.
User has a bit field AccountIsDisabled. </p>
<p>In my Data Model I have a partial class extending the EF model class for Company.
On this the call to ActiveEmployees returning all Employees that are active for the company. </p>
<p>My problem is that this code is generating a query explosion.
For a company of 1K employees I am getting 1K calls to the DB. It seems EF is creating a call for each employee when navigating to the User table. </p>
<p>I have tried many methods to force eager loading but to no avail. </p>
<p>Anyone out there see a reason that I am getting this query explosion? </p>
<pre><code>namespace JCS.Data
{
public partial class Company : IIdentifiable
{
public IEnumerable<Employee> ActiveEmployees
{
get
{
return Employees.Where(e => !e.User.AccountIsDisabled);
}
}
}
}
</code></pre>
<p>Sorry for the missing info. </p>
<p>The explosion of queries occurs when a bool property on the related Employee class is accessed. Like so</p>
<pre><code>namespace JCS.Data
{
public partial class Employee : IIdentifiable
{
public bool ApprovesTimesheets
{
get
{
return Company.ActiveEmployees.Any(
employee => employee.TimesheetApproverEmployeeID == ID
&& employee.TimesheetsEnabled);
}
}
}
}
</code></pre>
<p>So anywhere in the code I go </p>
<pre><code>bool approvesTimesheets = employee.ApprovesTimesheets;
</code></pre>
<p>I get the 1K queries. </p>
<p>I have tried adding ToLis() to the Company.ActiveEmployees. No joy. </p>
<p>e.g.
in Employee class</p>
<pre><code>var activeEmployees = Company.ActiveEmployees.ToList();
var approvesTimesheets = activeEmployees .Any(
employee => employee.TimesheetApproverEmployeeID == ID
&& employee.TimesheetsEnabled);
</code></pre>
<p>the latest in a long line of failed attempts:</p>
<pre><code>public List<Employee> ActiveEmployees
{
get
{
var employees = Employees.AsQueryable().Include(x => x.User).ToList();
return employees.Where(e => !e.User.AccountIsDisabled).ToList();
//return Employees.Where(e => !e.User.AccountIsDisabled);
}
}
</code></pre>
| <p>You need to call <code>.ToList()</code> or <code>ToListAsync()</code> to get all the data at once otherwise it will get the data on the fly per record.</p>
<p>This is the problem with deferred execution VS immediate execution. When you don't materialize the list with <code>.Where(foo).ToList()</code> it loads each record whenever you try to access it therefore the 1000 DB calls.</p>
<p>edit: Please note that you are also using a navigational property that points to another object (my guess is that it's object mapped directly to a table ) so, when trying to get that object you also do additional DB calls. to avoid that do something like this :</p>
<pre><code>public partial class Company : IIdentifiable
{
public IEnumerable<Employee> ActiveEmployees
{
get
{
return Employees.Where(e => !e.User.AccountIsDisabled).Include(x=>x.User).ToList();
}
}
}

Bash: using function with pipe as argument for another function <p>I'm trying to make function-wrapper for another functions to distinguish its in terminal</p>
<pre><code>red_line="$(tput setaf 1)## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## $(tput sgr 0)"
function wrapper {
echo $red_line;
echo "$(tput setaf 1)## $(tput setab 7)$(tput setaf 0)$1 $(tput sgr 0)";
$2;
echo $red_line;
}
function foo {
wrapper "custom command description" "ps axo pid,stat,pcpu,comm | tail -n 10;"
}
</code></pre>
<p>but error was occurred: <code>ps: illegal argument: |</code></p>
<p>I've tried to use <code>$(ps ... | tail -n 10)</code> and backticks instead of string and then print out result in wrapper with <code>echo $2</code>, but caught another errors</p>
<p>Also tried <code>"eval $(ps ... | tail -n 10)"</code> and it also didn't work.</p>
<p>Everything works just fine w/o wrapper:</p>
<pre><code>function pss {
echo $red_line
echo "$(tput setaf 1)## $(tput setab 7)$(tput setaf 0)formatted 'ps ax' command $(tput sgr 0)"
ps axo pid,stat,pcpu,comm | tail -n $1;
echo $red_line
}
</code></pre>
<p><a href="http://i.imgur.com/eLUqQPk.jpg" rel="nofollow">result screenshot</a></p>
| <p>Tnx @chepner for referring post about passing complex commands as argument.
But the actual problem was with mess with double quotes in functions arguments in <code>echo</code> and <code>wrapper</code>.</p>
<p>Correct code:</p>
<pre><code>red_line="$(tput setaf 1)## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## ## $(tput sgr 0)"
function wrapper {
echo $red_line;
echo "$(tput setaf 1)## $(tput setab 7)$(tput setaf 0)$1 $(tput sgr 0)";
echo "$2";
echo $red_line;
}
function pss {
res="$(ps axo pid,stat,pcpu,comm | tail -n $1)"
wrapper "custom command description" "$res"
# also work:
# wrapper "custom command description" "$(ps axo pid,stat,pcpu,comm | tail -n $1)"

C++ Tweetnacl hash a file without read whole file to memory <p>I'm using tweetnacl to generate sha512 hashes of strings and file. For strings it works quite well but i have no idea how to do it with files.</p>
<p>The signature of the function ist</p>
<pre><code>extern "C" int crypto_hash(u8 *out, const u8 *m, u64 n);
</code></pre>
<p>where u8 is of type unsigned char and u64 is of unsigend long long.
For string a can use it like that</p>
<pre><code>string s("Hello");
unsigned char h[64];
crypto_hash(h, (unsigned char *)s.c_str(), s.size());
</code></pre>
<p>This works great for a string and small files but if i want to create a hash for a big file, it is not viable and uses to much memory. I searching for a solution to read the file byte by byte and pass it as unsigend char pointer to that function. Has anyone a idea how to achieve that?</p>
<p>P.S Sorry for the poor English.
p.s.s I use tweetnacl because of the small size and i need only the hashing function.</p>
| <p>Probably the easiest way is to use a <a href="https://en.wikipedia.org/wiki/Memory-mapped_file" rel="nofollow">memory-mapped file</a>. This lets you open a file and map it into virtual memory, then you can treat the file on disk as if it is in memory, and the OS will load pages as required.</p>
<p>So in your case, open your file and use <code>mmap()</code> to map it into memory. Then you can pass the pointer into your <code>crypto_hash()</code> function and let the OS do the work.</p>
<p>Note that there are caveats to do with how large the file is wrt virtual memory.</p>

<p>You most likely have an older version of the OTA Client in your HPQC installation and from my experience version 12.53 of the MS Word ALM Add-in isn't compatible with some older versions of the OTA Client on the server.</p>
<p>To fix this I had to remove version 12.53 of the MS Word ALM Add-in via Uninstall from Installed Programs and the download and re-install a version compatible with my own.</p>

Running the ceylon typechecker from ceylon, like in typechecker/src/main/Main.java <p>I'm running the ceylon typechecker from a ceylon project with a run.ceylon which is exactly a ceylon version of typechecker/src/main/Main.java. </p>
<p>This project is supposed to typecheck itself.</p>
<p>It compiles without errors, but at runtime cannot load dependencies for typechecking. </p>
<p>file: source/com/example/withmodule/module.ceylon</p>
<pre><code>native("jvm")
module com.example.withmodule "1.0" {
import com.redhat.ceylon.typechecker "1.3.0" ;
//import com.redhat.ceylon.module-resolver "1.3.0";
}
</code></pre>
<p>file: source/com/example/withmodule/run.ceylon</p>
<pre><code>import java.io{File}
import com.redhat.ceylon.cmr.api{RepositoryManager}
import com.redhat.ceylon.cmr.ceylon{CeylonUtils}
import com.redhat.ceylon.compiler.typechecker{TypeCheckerBuilder}
import com.redhat.ceylon.compiler.typechecker.io.cmr.impl{LeakingLogger}
shared void run(){

.verbose(true)
.statistics(true);
for (String path in args) {
tcb.addSrcDirectory( File(path));
}
tcb.typeChecker.process();
}
</code></pre>
<p>It compiles without errors.</p>
<p>But when running it produces errors:</p>
<pre><code>error [package not found in imported modules: 'com.redhat.ceylon.cmr.api' (add module import to module descriptor of 'com.example.withmodule')] at 2:7-2:31 of com/example/withmodule/withmodule.ceylon

</code></pre>
<p>This makes no sense to me, because compilation and typechecking had succeded just before.</p>
<p>It's a fresh ceylon 1.3.0 download, not installed, simply run from the unzipped .tar.gz.</p>
<p>What extra information does the typechecker need that it hadn't got?</p>
| <p>So the issue here is that the typechecker we use in the test runner <code>typechecker/src/main/Main.java</code> is only able to understand things defined in Ceylon source code. It is <em>not</em> able to read a compiled Java <code>.jar</code> archive and typecheck your Ceylon source code against the classes in that archive.</p>
<p>So to be able to typecheck Ceylon code that depends on Java binaries, you would need more infrastructure, including what we call a "model loader" which is responsible for building a Ceylonic model of the Java binary <code>.class</code>es. There are a number different model loaders in the Ceylon ecosystem—one for <code>javac</code>, one for Eclipse, one for IntelliJ, one that uses Java reflection, one for Dart, one for typescript, one for JS—and they're all very specific to a particular compilation environment.</p>
<p>So the tests for the Ceylon typechecker, which don't depend on <code>javac</code>, IntelliJ, Eclipse, etc, etc, don't feature any sort of Java interop. Your code can successfully typecheck things defined in Ceylon source code, including code that depends on Ceylon modules with <code>.src</code> archives produced by the Ceylon compiler, but it can't typecheck things defined in a Java <code>.jar</code> archive.</p>
<p>I hope that helps.</p>

How to know onSurfaceTextureAvailable is called for which TextureView <p>I am writing an application where I need to display two <code>TextureView</code>(s) on my activity. I am attaching videos to each of the <code>TextureView</code> instance using <code>MediaPlayer</code> objects using the following code inside <code>onSurfaceTextureAvailable()</code>:</p>
<pre><code>@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int i1) {
Surface surface = new Surface(surfaceTexture);
mMediaPlayer1 = new MediaPlayer();
try {
mMediaPlayer1.setDataSource(<filePath>);
} catch (IOException e) {
Log.e(TAG, "Unable to load the file from the file system", e);
return;
}
mMediaPlayer1.setSurface(surface);
mMediaPlayer1.setLooping(true);
mMediaPlayer1.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
isPlaybackReady = true;
}
});
mMediaPlayer1.prepareAsync();
}
</code></pre>
<p>Now, if I have two instances of <code>TextureView</code>, how would I know the callback into <code>onSurfaceTextureAvailable(...)</code> is for which <code>TextureView</code>. </p>
<p>The other way is to setup the <code>MediaPlayer</code> objects outside the <code>onSurfaceTextureAvailable(...)</code>, by getting a hold over the associated <code>SurfaceTexture</code> by calling <code>TextureView.getSurfaceTexture()</code>. I tried that as well but it always returns <code>null</code>. Is there something else that I need to do for this?</p>
| <p>You can just set two instances of TextureView with different listener.</p>
<pre><code>textureView1.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int i1) {
doSomething(textureView1, surfaceTexture, i, i1);
}
// implement other methods
});
textureView2.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int i1) {
doSomething(textureView2, surfaceTexture, i, i1);
}
// implement other methods
});

Rails first or initialize not working <p>I have a product.<br>
I have an order.<br>
I have a booking in between.</p>
<p>Whenever I make a booking from the product to the order it saves a new <strong>unique</strong> booking. </p>

<li>Not make a new booking, but find and overwrite an old one, if the product has already been booked once.</li>
<li>If the product has already been booked on the order, but no changes are made, no database transactions are made. </li>

C++ uses twice the memory when moving elements from one dequeue to another <p>In my project, I use <a href="https://github.com/pybind/pybind11" rel="nofollow">pybind11</a> to bind C++ code to Python. Recently I have had to deal with very large data sets (70GB+) and encountered need to split data from one <code>std::deque</code> between multiple <code>std::deque</code>'s. Since my dataset is so large, I expect the split not to have much of memory overhead. Therefore I went for one pop - one push strategy, which in general should ensure that my requirements are met. </p>
<p>That is all in theory. In practice, my process got killed. So I struggled for past two days and eventually came up with following minimal example demonstrating the problem.</p>
<p>Generally the minimal example creates bunch of data in <code>deque</code> (~11GB), returns it to Python, then calls again to <code>C++</code> to move the elements. Simple as that. Moving part is done in executor.</p>
<p>The interesting thing is, that if I don't use executor, memory usage is as expected and also when limits on virtual memory by ulimit are imposed, the program really respects these limits and doesn't crash.</p>
<p><strong>test.py</strong></p>
<pre><code>from test import _test
import asyncio
import concurrent
async def test_main(loop, executor):
numbers = _test.generate()
# moved_numbers = _test.move(numbers) # This works!
moved_numbers = await loop.run_in_executor(executor, _test.move, numbers) # This doesn't!
if __name__ == '__main__':
loop = asyncio.get_event_loop()
executor = concurrent.futures.ThreadPoolExecutor(1)
task = loop.create_task(test_main(loop, executor))
loop.run_until_complete(task)
executor.shutdown()
loop.close()
</code></pre>

</code></pre>
<p><strong>Observations:</strong></p>
<ul>
<li>When the moving part is not done by executor, so we just call <code>moved_numbers = _test.move(numbers)</code>, all works as expected, memory usage showed by htop stays around <code>11Gb</code>, great!.</li>
<li>When moving part is done in executor, the program takes double the memory and crashes.</li>
<li><p>When limits on virtual memory are introduced (~15Gb), all works fine, which is probably the most interesting part.</p>
<p><code>ulimit -Sv 15000000 && python3.5 test.py</code> >> <code>Done!</code>.</p></li>
<li><p>When we increase the limit the program crashes (150Gb > my RAM).</p>
<p><code>ulimit -Sv 150000000 && python3.5 test.py</code> >> <code>[1] 2573 killed python3.5 test.py</code></p></li>
<li><p>Usage of deque method <code>shrink_to_fit</code> doesn't help (And nor it should)</p></li>

Python 3.5.2
pybind11 latest release - v1.8.1
</code></pre>
<p><strong>Note</strong></p>
<p>Please note that this example was made merely to demonstrate the problem. Usage of <code>asyncio</code> and <code>pybind</code> is necessary for problem to occur. </p>
<p>Any ideas on what might be going on are most welcomed.</p>
| <p>The problem turned out to be caused by Data being created in one thread and then deallocated in another one. It is so because of malloc arenas in glibc <a href="https://siddhesh.in/posts/malloc-per-thread-arenas-in-glibc.html" rel="nofollow">(for reference see this)</a>. It can be nicely demonstrated by doing:</p>
<pre><code>executor1 = concurrent.futures.ThreadPoolExecutor(1)
executor2 = concurrent.futures.ThreadPoolExecutor(1)
numbers = await loop.run_in_executor(executor1, _test.generate)
moved_numbers = await loop.run_in_executor(executor2, _test.move, numbers)
</code></pre>
<p>which would take twice the memory allocated by <code>_test.generate</code> and</p>
<pre><code>executor = concurrent.futures.ThreadPoolExecutor(1)
numbers = await loop.run_in_executor(executor, _test.generate)
moved_numbers = await loop.run_in_executor(executor, _test.move, numbers)
</code></pre>
<p>which wound't.</p>
<p>This issue can be solved either by rewriting the code so it doesn't move the elements from one container to another (my case) or by setting environment variable <code>export MALLOC_ARENA_MAX=1</code> which will limit number of malloc arenas to 1. This however might have some performance implications involved (There is a good reason for having multiple arenas).</p>

Vimrc not updating <p>I am trying to setup vim to wrap my git commits to 72 characters but I am having trouble doing so. When I edit ":e $myvimrc" and add the settings to wrap the text it doesn't seem to work. I tried to open the vimrc file directly form my program files to check that the changes I have made had indeed been saved, but they are not showing in the file.</p>
<p>Strange thing is that when I open the vimrc file in vim to edit it the changes I made are still there, they just don't seem to be saving to the actual file.</p>
<p>I have tried to edit the vimrc directly as well but it wont allow me to save in that location. Hopefully im just doing something silly and if I am I apologies, very fresh to git and vim. Thanks in advance </p>
| <p>usually you don't need do special setting for gitcommit Filetype. Because GITCOMMIT was pre-defined as <code>wrap & textwidth=72</code> under your <code>$VIMRUNTIME/ftplugin/gitcommit.vim</code></p>
<p>Check if you have <code>filetype on</code> in your vimrc, so that the filetype plugins are activated. </p>

Is it possible to extend Test Cases in Nightwatch? <p>Does anyone has experience with extending Test Cases in Nightwatch.
I want to have some main Test Case and than the same Test Case to extend it with few more functions.
For example I have one Test Case which works fine on Desktop, but in order to work on Mobile device I need to click one more button,
so I want to crate new Test Case which will extend the Test Case for Desktop and than will click on the required button?I don't want to use custom commands</p>
| <p>I use page objects for this, where all "clicky" logic is abstracted into little functions about "user intent". That could be ideal for what you're talking about. I also use globals to inject my browser name into my test_settings in nightwatch.json so I can test on it, or include it in screenshot names. You could use this to decide whether to do your extra click.</p>
<pre><code>...
"ie10": {
"selenium_host": "10.20.3.161",
"desiredCapabilities": {
"browserName": "internet explorer",
"javascriptEnabled": true,
"acceptSslCerts": true,

Extracting href from Nodelist <pre><code>var downloadLinks = document.querySelectorAll('[href*="/Download"]');

var arrHREF = []; // create an Array to save hrefs
var i = 0;
for(; i<downloadLinks.length; i++) {
arrHREF.push(downloadLinks[i].href); // push hrefs in array
}
</code></pre>
<p>or you can write it in one line as (using the for loop property of declaring variables in execution brackets)</p>
<pre><code>for (var downloadLinks = document.querySelectorAll('[href*="/Download"]'), arrHREF = [], i = 0; i < downloadLinks.length; i++) arrHREF.push(downloadLinks[i].href);

Creating a recursive function for calculating R = x - N * y, with conditions <p>I wish to create a function for calculating R = x - N * y, where x and y are floats and N is the largest positive integer, so that x > N * y.</p>
<p>The function should only take the inputs of x and y.</p>
<p>I have previously created the function through a loop, but having trouble trying to convert it to recursion. My basic idea is something like:</p>
<pre><code>def florec(x, y):
if x > y:
R = x - N * y
florec(x, y_increased)
return R
</code></pre>
<p>My problem is that I can not figure out how to code "y_increased", meaning, how I can update N to N+1, and then call upon florec(x, (N+1)*y). Then update N+1 to N+2 and call upon florec(x, (N+2)*y) and so on.</p>
<p>Feeling quite stuck currently, so any help at all to move forward would be appreciated.</p>
| <p>Here's a recursive way of computing R:</p>
<pre><code>def florec(x, y):
if x > y:
return florec(x-y, y)
return x
</code></pre>
<p>(Note it only works for positive floats.)</p>
<p>I don't know if this addresses your recursion issues. Maybe this use case is not best suited to illustrate recursion.</p>

Get parent url parameter <p>I have this routing</p>
<pre><code>import { ModuleWithProviders} from '@angular/core';

<p>I want to get that lang parameter from my function which looks:</p>
<pre><code>translateThis(lang: any) {
// this line works fine
this.translate.use(lang);
// this doesn't
this.sub = this.route.parent.queryParams.subscribe(
(param: any) => {
let lang = param['lang'];
console.log(param);
console.log(userId);
});
}
</code></pre>
<p>but it stops working as soon i uncomment this.sub code (whole 6 lines). without that it works ok</p>
<pre><code>translateThis(lang: any) {
this.translate.use(lang);
}
</code></pre>
<p>How can I get that lang value? I tried <code>params</code> as well instead of queryParams but result is same</p>
| <p>I guess this is what you are looking for</p>
<pre><code>translateThis() {
// Subscribe to router params observable
this.sub= this.route.parent.params.subscribe(
param => {
let lang = param['lang'];
console.log(lang);
// Call method or something
this.translate.use(lang);
});
}
</code></pre>
<p>Here's a full example of what I believe you need. Note that subscribtion to route params should be unsubscribed manually</p>
<pre><code>export class ChildComponent implements OnInit, OnDestroy {
private sub;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
// Subscribe to router params observable
this.sub= this.route.parent.params.subscribe(
param => {
let lang = param['lang'];
console.log(lang);
// Call method or something
this.translateThis(lang);
});
}
ngOnDestroy() {
// Unsubscribe from router params observable
this.sub.unsubscribe();
}
translateThis(lang: any) {
// Do your thing here
// this.translate.use(lang);

How to display waiter while resolving data in Angular 2.0.0? <p>I've project based on Angular 2.0.0, and I want to display waiter (gif or text) while navigating routes, which must resolve data like this:</p>
<pre><code> {
path: 'profile',
loadChildren: () => System.import('../profile/profile.module'),
resolve: {
profile: ProfileResolver
},
},
</code></pre>
<p>Also, preloader need to be applied to every route in project.
Thanks.</p>
| <p>I'd say you can create a service which would keep eye on routing events and based on <code>NavigationStart</code> & <code>NavigationEnd</code> event it will <code>show/hide</code> loading based on <code>isLoading</code> flag value with combination of <code>[hidden]</code>.</p>
<p><strong>Code</strong></p>
<pre><code>isLoading: bool = false;
constructor(router:Router) {
router.events.subscribe(event:Event => {
if(event instanceof NavigationStart) {
this.isLoading = true;
}
if(event instanceof NavigationCancel || event instanceof NavigationError) {
this.isLoading = false;
}
}
}

Naming the clusters of leaflet by unigue names like A, B,C instead of numbers <p>I have been trying to name the clusters of leaflet by unique name, can any one give the solution for this ?</p>
<p>Context: I have some location pointers, where it get clustered into 5, 3, 4, 3 at some zoom level, instead of showing the numbers on clusters, i need to show by unique name like A for 5, B for 3, C for 4, D for 3 </p>
| <p>Starting from the <a href="http://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-custom.html" rel="nofollow">custom cluster example</a>, you can think of something along those lines:</p>
<pre><code>var alphabet = "abcdefghijklmnopqrstuvwxyz".split("");
var n = -1;
var markers = L.markerClusterGroup({
maxClusterRadius: 120,
iconCreateFunction: function (cluster) {
n++;
return L.divIcon({ html: alphabet[n], className: 'mycluster', iconSize: L.point(40, 40) });
},
});
</code></pre>
<p>It will only work for 26 unique names of course, but you get the idea.</p>

Avoiding primary key constraint violation when using timestamp as the primary key <p>I have a database table where the primary key is defined as a timestamp. The application inserts records to the database based on a certain event that is triggered and the timestamp used will be the one that created this instance. Since this application is running on multiple servers and that event is triggering at the same time in more than one of these servers at the same time, in some cases, the data doesn't get inserted to the database due to the primary key violation. </p>
<p>What could I possible change in order to avoid this situation? The ideas that I have at the moment are, </p>
<ol>
<li><p>Waiting a random time before executing the database insertion. </p>
<pre><code>Random r = new Random();
long time = r.nextLong() % 1000;
time = time < 0 ? -time : time; // making sure that the waiting time is positive
try {
Thread.sleep(time);
} catch (InterruptedException e) {
throw new CustomeException(e);
}
Table1DataAccess.getInstance().insert(new Date(), "some description"); // inserting data into the table which has two fields.
</code></pre></li>
<li><p>Making the primary key a composite one.</p></li>
</ol>
<p>Neither of them seems like good solutions to me, could anyone point me in the right direction?</p>
<p>P.S. The table to which I tried inserting data had the timestamp column in <code>Date</code> type and I guess it only has it's precision down to seconds. When I used the type <code>timestamp</code> instead, it offered a default precision of microseconds and it can offer nanoseconds at maximum. </p>
| <p>Do not use timestamp as primary key field.</p>
<p>Use Integer or BigInt for primary key auto increment fields</p>

How to run a zeppelin notebook using REST api and return results in python? <p>I am running a zeppelin notebook using the following REST call from python:</p>
<p><code>import requests
requests.post('http://x.y.z.x:8080/api/notebook/job/2BZ3VJZ4G').json()</code></p>
<p>The output is {u'status': u'OK'}</p>

</code></pre>
<p>and received the same output {u'status': u'OK'}. </p>
<p>Can somebody help me to retrieve the results from zeppelin in python?</p>
| <p>Zeppelin has introduced a synchronous API to run a paragraph in its latest yet to be releases 0.7.0 version. You can clone the latest code form their repo and build a snapshot yourself. URL for API is <a href="http://[zeppelin-server]:[zeppelin-port]/api/notebook/run/[notebookId]/[paragraphId]" rel="nofollow">http://[zeppelin-server]:[zeppelin-port]/api/notebook/run/[notebookId]/[paragraphId]</a>.

Laravel count # of results from whereHas <p>I have the below relationship. <code>User->hasMany(Posts)</code> and <code>User->belongsToMany(Following)</code>.
Now i want to retrieve the following. Get all the following users of a user that have a specific type of <code>post</code>. I have come so far</p>
<pre><code>$writers = $user
->following()
->with('posts')
->whereHas('posts' ,function($query){
$query->where('type','article');
})
->get();
</code></pre>
<p>Which is ok and returns only the Users that have at least 1 article type post.
What i want here is to also in the response</p>
<pre><code>{
"id": 37,
"name": "Telis Xrysos",
"email": "txrysos@mail.com",
"url": "",
"personal_quote": "",

]
}
</code></pre>
<p>To include a count of how many of his posts are articles. I could do a count afterwards at the <code>posts</code> attribute although that is just temporary and will be removed afterwards.</p>
<p>I have tried this but all i get is an extra attribute for each user <code>articles_count = []</code></p>
<pre><code>public function articlesCount()
{
return $this->posts()->selectRaw('id, count(*) as aggregate')->where('type','article')->groupBy('id');
}
$writers = $user

->with('posts')
->with('articlesCount')
->whereHas('posts' ,function($query){
$query->where('type','article');
})
->get();
</code></pre>
| <p>i'm simply put a custom attribute in Eloquent</p>
<pre><code> protected $appends = ['ArticleCount'];
public function getArticleCountAttribute(){
return $this->posts->count();
}
</code></pre>
<p>don't forget the relationship too : </p>
<pre><code>public function posts(){
return $this->hasMany('app\posts','id_user','id');

Does the echo command append any extra character when writing to text file? <p>I am trying to create a shortcut using batch file. I mimic the following manual steps to do that, but although the manually created file works properly as a shortcut, the shortcut created by batch files command line command does not work-</p>
<p>Creating shortcuts manually:</p>
<ol>
<li>Create a text file</li>
<li><p>Add following content to the text file and save:</p>
<pre><code>[InternetShortcut]
URL=file:///D:\Logs
</code></pre></li>
<li>Rename the text file to have .url extension.</li>
</ol>
<p>That process creates a shortcut to D:\Logs directory.</p>
<p>Now I do the following to create shortcut using Batch file-</p>
<pre><code>(
ECHO [InternetShortcut]
ECHO URL=file:///D:\Logs
) > E:\myshortcut.url
</code></pre>
<p>But the shortcut does not work. I checked the contents and they look exactly as what I have in the manually created file.</p>
<p>So what is the difference between those manually created and batch file created files?</p>
| <p>This works for me:</p>
<pre><code>echo [InternetShortcut]> E:\myshortcut.url
echo URL=file:///D:\Logs>> E:\myshortcut.url
</code></pre>
<p>Note that you must <strong>not</strong> have a space before the redirection <code>></code> or <code>>></code> because that <em>will</em> be echoed into the file.</p>

ckeditor set custom skinpath <p>I have a problem with the CKEDITOR. I installed it with bower and changed the basepath. So CKEDITOR works.
My problem now is to laod a custom skin, because i download it also with bower.</p>
<p>This is the code:</p>
<pre><code><textarea id="editor-<?= $block_count ?>" name="block[<?= $block_count ?>][text][]" rows="10" cols="80" class="form-control"></textarea>
<script>
CKEDITOR.replace('editor-<?= $block_count ?>',{
customConfig: '../../dist/scripts/ckeditor.js',
skin: 'office2013'
});
</script>

<p>But if it want to laod the skin i get this error message:</p>
<pre><code>ckeditor.js:76 GET
htttp://myurl.com/src/bower_components/ckeditor/skins/office2013/editor.css?t=G87D
</code></pre>
<p>Can i define a skinpath to load it from teh bower path like:</p>
<pre><code>CKEDITOR.replace('editor-<?= $block_count ?>',{
customConfig: '../../dist/scripts/ckeditor.js',
skinpath: 'src/bower_componnts/ckeditor-office2013-skin/office2013/',
skin: 'office2013'
});
</code></pre>
| <p>Yes you can. <a href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-skin" rel="nofollow">Check the documentation</a>. Quoting docs:</p>
<blockquote>
<p>It is possible to install skins outside the default skin folder in the editor installation. In that case, the absolute URL path to that folder should be provided, separated by a comma ('skin_name,skin_path').</p>
</blockquote>
<pre><code>config.skin = 'moono';
config.skin = 'myskin,/customstuff/myskin/';
</code></pre>
<p>So, something similar should do the trick:</p>
<pre><code>skin: 'office2013,/src/bower_components/ckeditor-office2013-skin/office2013/'

</code></pre>
<p>Which is same as mentioned by @Weiziyoung in original problem.</p>
<p>The solution is as I mentioned you need to provide the path to chromedriver in place of chrome browser like</p>
<pre><code>driver = webdriver.Chrome("E:\Jars\chromedriver.exe")
</code></pre>
<p>It will resolve the problem</p>

Caliburn Micro ViewLocator with different namespace <p>I'm using Caliburn Micro for MVVM. Now I have the following situation. I have a UserControl with View and ViewModel in my first assembly <code>assembly1</code> in <code>namespace1</code>. If I use it in an second assembly <code>assembly2</code> that has the same namespace <code>namespace1</code> (it´s in the same solution) everything works fine.</p>
<p>Now I'd like to use my ViewModel in another <code>Solution</code> with namespace <code>namespace3</code>. If I try this I always get the error, that View couldn't be located.</p>
<p>I build up a workaround that sets the Binding manually in the bootstrapper (using Ninject).</p>
<pre><code>protected override void Configure()
{
_kernel = new StandardKernel();
_kernel.Bind<OverlayManagerView>().To<OverlayManagerView>().InSingletonScope();
_kernel.Bind<OverlayManagerViewModel>().To<OverlayManagerViewModel>().InSingletonScope();
base.Configure();
}
protected override void OnStartup(object sender, System.Windows.StartupEventArgs e)
{
ViewModelBinder.Bind(IoC.Get<OverlayManagerViewModel>(), IoC.Get<OverlayManagerView>(), null);
...
}
</code></pre>
<p>This is working, but if I'd like to use my ViewModels from <code>assembly1</code> I won't always set the Binding manually and as Singleton. </p>
<p>Is there a way to tell the <code>Caliburn ViewLocator</code> that Views might be at a different namespace?</p>
<p>I tried following not working...</p>
<pre><code> ViewLocator.AddNamespaceMapping("namespace1", "namespace3");
ViewLocator.AddNamespaceMapping("namespace1", "namespace1");
ViewLocator.AddNamespaceMapping("namespace3", "namespace1");
</code></pre>
<p>Maybe someone knows a solution.</p>
| <p>In your <code>Configure</code>method you should use :</p>
<pre><code>ViewLocator.AddSubNamespaceMapping("ViewModelsNamespace", "ViewsNamespace");
</code></pre>
<p>and you have to override the following method :</p>
<pre><code> protected override IEnumerable<Assembly> SelectAssemblies()
{
var assemblies = new List<Assembly>();
assemblies.AddRange(base.SelectAssemblies());
//Load new ViewModels here
string[] fileEntries = Directory.GetFiles(Directory.GetCurrentDirectory());
assemblies.AddRange(from fileName in fileEntries
where fileName.Contains("ViewModels.dll")
select Assembly.LoadFile(fileName));
assemblies.AddRange(from fileName in fileEntries
where fileName.Contains("Views.dll")
select Assembly.LoadFile(fileName));
return assemblies;
}
</code></pre>
<p>in order to let Caliburn know about your new dlls.</p>

How to create Transparent text in pdfBOX or add opacity to the text with the help of pdfBOX? <p>I am not getting how to add transparent text with the help of pdfBOX.</p>
| <p>Here's something that shows alpha with 1.8 (you should use 2.*, that is a bit easier).</p>
<pre><code> PDExtendedGraphicsState gs1 = new PDExtendedGraphicsState();
gs1.setNonStrokingAlphaConstant(1f);
PDExtendedGraphicsState gs2 = new PDExtendedGraphicsState();
gs2.setNonStrokingAlphaConstant(0.2f);
Map<String, PDExtendedGraphicsState> graphicsStatesMap = page.getResources().getGraphicsStates();
if (graphicsStatesMap == null)
{
graphicsStatesMap = new HashMap<String, PDExtendedGraphicsState>();
}
graphicsStatesMap.put("gs1", gs1);
graphicsStatesMap.put("gs2", gs2);
page.getResources().setGraphicsStates(graphicsStatesMap);
cs.setFont(PDType1Font.HELVETICA_BOLD, 60);
cs.setNonStrokingColor(255, 0, 0);
cs.appendRawCommands("/gs1 gs\n");
cs.beginText();
cs.moveTextPositionByAmount(50, 600);
cs.drawString("Apache PDFBox 1");
cs.endText();
cs.setNonStrokingColor(0, 0, 255);
cs.appendRawCommands("/gs2 gs\n");
cs.beginText();
cs.moveTextPositionByAmount(70, 620);
cs.drawString("Apache PDFBox 2");
cs.endText();
cs.close();

How to create user module at run-time? <p>I have different set of math expressions that must be evaluated at run-time. Currently the task is done by replacing symbols with equivalent values and <code>eval</code> the result. (could be done by any existing symbolic packages)</p>
<p>Now, refer to the definition of modules in Julia-lang:</p>
<blockquote>
<p>Modules in Julia are separate variable workspaces, i.e. they introduce
a new global scope .... Modules allow you to create top-level definitions (aka
global variables) without worrying about name conflicts when your code
is used together with somebody elseâs.</p>
</blockquote>
<p>And with the power of Julia to do meta-things,<br>
I'm wondering if it is possible to create anonymous modules at run-time <code>m=Module()</code>, and use them as a scope to evaluate expressions <code>eval(m, :(a+b))</code>.<br>
But I simply can't find a way to load variable into the run-time modules.
Although I could get result with:</p>
<pre><code>julia> ex=:(module mo; a=1; b=4; end)
julia> eval(ex)
julia> eval(mo,:(a+b))
</code></pre>
<p>I prefer more functional way, using anonymous modules.<br>
Any Help.</p>
| <p>This works:</p>
<pre><code>julia> m=Module()
anonymous
julia> eval(m, :(a=5))
5
julia> m.a
5
julia> eval(m, :(a))
5
julia> eval(m, :(2a))
10

Exception while trying to read file usin PCLStorage from PCL project <p>I am trying to get file from <code>PCL</code> project using <code>PCLStorage</code> as below. I am using Xamarin in Visual Studio 2015 Professional.</p>
<pre><code>IFile file = await FileSystem.Current.GetFileFromPathAsync("file\path");
</code></pre>
<p>But I am getting exception as:</p>
<blockquote>
<p>System.NotImplementedException: This functionality is not implemented
in the portable version of this assembly. You should reference the
PCLStorage NuGet package from your main application project in order
to reference the platform-specific implementation.</p>
</blockquote>
| <p>You need to add the PCLStorage NuGet to both your PCL and your platform specific project.</p>
<p>So if you have the following solution:</p>
<pre><code>PCL
Android
iOS
</code></pre>
<p>You would need to add it to all of them:</p>
<pre><code>PCL
PCLStorage
Android
PCLStorage
iOS
PCLStorage
</code></pre>
<p>Why? Because the NuGet uses the bait and switch technique, where the PCL contains a simple facade with the bait. At runtime this gets switched out with platform specific implementation.</p>

setContentView in retrofit response success doesn't show all the information in scroll? <p>I'm using retrofit and coordinatorlayout. All seems that work fine but I'm getting a small problem. That I want to do is that the layout will display in the moment that the response is success. For this reason, I'm calling the setContentView inside the response (I don't know if this is a good practice or not)</p>
<p>My problem is that this works, but the layout don't do the scroll in all the information. He cut the last lines of text. If I call the setContentView in the oncreate method the scroll in the coordinatorlayout is ok (show all the information) but in this scenario I can see the layout design before all the correct images and text when finish the success response.</p>
<p>Somebody know how can I fix this problem??</p>
<p>Thanks in advance</p>

<pre><code>tblinsurance is refer to tblinsuranceplan
tblinsuranceplan is refer to tblpatient
tblpatient is refere to tblPriscription
and last tblPriscription is refere to tblPriscriptionDetail
tblPriscriptionDetail : tblPriscription : tblpatient : tblinsuranceplan : tblinsurance

<p>Can you tell me that how to do that</p>
| <p><strong>Try:</strong></p>
<p>Replace <code>*</code> with column names you want to select.</p>

Get json array response and store in another array <p>I have cURL function which make calls to api based on ID which I provide and return data in array. So far everything works perfectly. What I want and can't figure out is this:</p>
<p>I have foreach which display in table all orders lie</p>
<pre><code>@foreach($orders as $order)
$order->address
$order->time_created
$order->price
... etc
@endforeach
</code></pre>
<p>Is it possible to put this cURL inside the foreach and add on each row based on <code>$order->order_id</code> to show some more data from the array?</p>
<p>So something like this</p>
<pre><code>@foreach($orders as $order)
$order->address
$order->time_created
$order->price
... etc
$url = get_curl_content_tx("http://example.com/".$order->order_id);
$data = json_decode($url,true);
@foreach ( $data as $moreData )
@if ( $moreData['data'] == $order->time_created )
// show something
@else
// show other thing
@endif
@endforeach
@endforeach
</code></pre>
<p>My problem is that I can't figure how to loop the url so I can get all <code>orders_id</code> i.e.</p>
<pre><code>$url = get_curl_content_tx("http://example.com/1");
$url = get_curl_content_tx("http://example.com/2");
$url = get_curl_content_tx("http://example.com/3");
$url = get_curl_content_tx("http://example.com/4");
$url = get_curl_content_tx("http://example.com/5");
$url = get_curl_content_tx("http://example.com/6");
</code></pre>
<p>So then I can perform my <code>if/else</code> block. Framework which I use is Laravel 4.2. </p>
<p>Hope it is clear enough what I want to accomplish. If is not I will try to clear things..</p>
<p>EDIT: Example what it should be:</p>
<pre><code><table>

| <p>You can use laravel's <code>unique</code> method for collections to remove duplicate order id's before iterating them.</p>
<pre><code>$collection = collect([
['name' => 'iPhone 6', 'brand' => 'Apple', 'type' => 'phone'],
['name' => 'iPhone 5', 'brand' => 'Apple', 'type' => 'phone'],
['name' => 'Apple Watch', 'brand' => 'Apple', 'type' => 'watch'],
['name' => 'Galaxy S6', 'brand' => 'Samsung', 'type' => 'phone'],
['name' => 'Galaxy Gear', 'brand' => 'Samsung', 'type' => 'watch'],
]);
$unique = $collection->unique('brand');
$unique->values()->all();
</code></pre>

editing a model in more than one view <p>My target is, to modify a model in more than one view.
Since sometimes my models have many properties I want to modify them in more than one view. Something like:</p>
<p>first page edits 2 properties, second page edits 3 other properties,...</p>
<p>the model looks like this:</p>
<pre><code>public class LoadViewModel
{
public int CurrentPage { get; set; } = -1;
public PageViewModel PageViewModel { get; set; }
}
public class PageViewModel
{
public string Param1 { get; set; }
public string Param2 { get; set; }
public int Param3 { get; set; }
}
</code></pre>
<p>my view on the Index-page looks like this:</p>
<pre><code>@model LoadViewModel
@using(Ajax.BeginForm("Load", "Home", new AjaxOptions {UpdateTargetId = "page"}, new {lvm = Model}))
{
<div id="page"></div>
<input type="submit"/>
}
</code></pre>
<p>and this is my action:</p>
<pre><code>public ActionResult Load(LoadViewModel lvm = null)
{
if (lvm == null) lvm = new LoadViewModel();
lvm.CurrentPage += 1;
TempData["CurrentPage"] = TempData["CurrentPage"] == null ? 0 : (int)TempData["CurrentPage"] + 1;
if (!partialViewDict.ContainsKey((int) TempData["CurrentPage"]))
TempData["CurrentPage"] = 0;
return PartialView(partialViewDict[(int)TempData["CurrentPage"]], lvm);
}
</code></pre>
<p>the pages are just partials that are mapped:</p>
<pre><code>private Dictionary<int, string> partialViewDict = new Dictionary<int, string>
{
{0, "Pages/_Page1"},
{1, "Pages/_Page2"},
{2, "Pages/_Page3"},
};
</code></pre>
<p>and designed like this:</p>
<pre><code>@using WebApplication1.Controllers
@model LoadViewModel
@{
TempData["CurrentPage"] = 0;
}
@Html.DisplayNameFor(m => m.PageViewModel.Param1)
@Html.EditorFor(m => m.PageViewModel.Param1)
</code></pre>
<p>this is working. When switching to Page2 the model is correctly set, but when hitting the <code>submit</code> the value of <code>Param1</code> (that I set in Page1) is resetted to <code>null</code> and only the values I set in the current partial are correct.</p>
<p>This is Page2:</p>
<pre><code>@using WebApplication1.Controllers
@model LoadViewModel
@{
TempData["CurrentPage"] = 1;
}
@Html.DisplayNameFor(m => m.PageViewModel.Param2)
@Html.EditorFor(m => m.PageViewModel.Param2)
</code></pre>
<p>When I add a <code>@Html.HiddenFor(m => m.PageViewModel.Param1)</code> into the partial, the value is still set. But I don't want the values to be resetted. I don't want to add an <code>@Html.HiddenFor</code> for all properties a set in a previous view. How can I prevent that the values are resetted when hitting <code>submit</code> without adding <code>@Html.HiddenFor</code> for all not listed attributes? Or is there any other possibility to catch my target?</p>
| <p>There's two pieces to this. First, the post itself, and getting that to validate. For that, each step should have its own view model, containing only the properties it's supposed to modify. This allows you to add all the validation you need without causing other steps to fail. In the end, you'll combine the data from all of these into your entity class or whatever.</p>
<p>Which brings us to the second piece. You need some way of persisting the data from each step. The only data that will exist after a POST is the data that was posted and anything in the session (which includes <code>TempData</code>). You could always create a bunch of hidden fields to store the data from the previous steps, but that can get a little arduous. Most likely, you'll just want to use the session.</p>
<p><code>TempData</code> is basically a specialized instance of <code>Session</code>, so which you use doesn't really matter. With <code>TempData</code>, you'll need to remember call <code>TempData.Keep()</code> for each of the keys you've set for each step or you'll lose the previous steps on the next request. <code>Session</code> will keep them around for the life of the session, but you should remember to remove the keys at the end with <code>Session.Remove()</code>.</p>

How to apply filter to get elements which have same value in JSONobjects inside JSON array using AngularJS <p>I have a JSON array with multiple(dynamic) JSON objects. I need to compare the objects and pick the keys which has the same value in all the objects. My JSON looks like,</p>
<pre><code>[

<p>I want to get the Keys which has same value. Example, CreateAccountName. It has same value in all the objects. </p>
<p>The tricky case is, the key itself dynamic. I cannot hardcode the key and do compare. The key name may change or another set of keys may come. I am looking for a generic solution to compare and get the "intersection" of the objects. </p>

ZingChart get crosshair position on click <p>The ZingChart <code>click</code> event states that the callback will receive an object. The <code>x</code> attribute will contain </p>
<blockquote>
<p>The x position of the click relative to the chart position</p>
</blockquote>
<p>I assume this is the cursor position in the window (i.e. pixels) relative to the position (top left corner?) of the div element that contains the graph.</p>
<p>Is there a way to get the "X" value of the crosshair position upon click as illustrated in the picture:
<a href="https://i.stack.imgur.com/WXdyf.png" rel="nofollow">Example</a></p>
<p>i.e. if the crosshair is at "0", I want to get that value upon click. When I use the <code>arg.x</code> of the click event, and the crosshair is at "0" I get 49, and I need 0.</p>

<p>Yes the values are relative the chart position. What you can do is use our API methods to get the chart information you need based on the xy location of the click. You will use <a href="https://www.zingchart.com/docs/api/api-methods/#zingchart__exec__api__getxyinfo" rel="nofollow">getxyinfo</a>, which will grab an array of information about the chart. It will grab scale information closest to where the click happened. This means if you click in between two nodes (for scale-x), whichever is closest to (x position from click) it will give you that information. The crosshair/guide works the same way when highlighting nodes, so this shouldn't be a problem. I just thought it was relevant to bring up.</p>

Quickly build large dict in elegant manner <p>I have a list with size about 30000: <code>['aa', 'bb', 'cc', 'dd', ...]</code>, from this list, I want to build a dict which maps element to index, so the result dict is <code>{'aa': 0, 'bb': 1, 'cc': 2, 'dd': 3, ...}</code>. Here comes my code:</p>
<pre><code>cnt = 0
mp = {}
for name in name_list:
mp[name] = cnt
cnt += 1
return mp
</code></pre>
<p>It seems my code is not concise and effective, so how to improve it?</p>
| <p>The shortest is to use <a href="https://docs.python.org/2/library/functions.html#enumerate"><code>enumerate</code></a> and a dict comprehension, I guess:</p>
<pre><code>mp = {element: index for index, element in enumerate(name_list)}
</code></pre>

Untar subfolders from a folder in linux <p>I have a directory, <code>/Landsat_Data/</code> which contains subdirectories (<code>Landsat_Data/Site1</code>, <code>Landsat_Data/Site2</code>, etc.). Each subdirectory contains <code>.tar.gz</code> files (e.g. <code>/Landsat_Data/Site2/LE70930862008092-SC20160107074735.tar.gz</code>, etc.) and each <code>.tar.gz</code> file contains tif or xml files like thisL</p>
<pre><code>-rw-r--r-- espa/ie 29952 2016-01-07 14:57 LT50930861991021ASA00_sr_snow_qa.tif
</code></pre>
<p>What I want to do is to untar each tar file into its own sub-subdirectory (e.g. <code>Landsat_Data/Site2/LE70930862008092-SC20160107074735/</code>).</p>
<p>So far, I am using this command line while being the Landsat_Data directories: </p>
<pre><code>find . -type f -name "*.tar.gz" -execdir tar -xvzf {} \;
</code></pre>
<p>However, this command extracts all the tif and xml files into each subdirectory (e.g. <code>Landsat_Data/Site2</code>) while I just want to untar the <code>LE70930862008092-SC20160107074735.tar.gz</code> to have a sub-sub-directory called <code>LE70930862008092-SC20160107074735</code> which contains all the tif and xml files. Any idea how I can achieve what I want?</p>
| <p>You might parse the filenames and cd into the directories before running <code>tar</code>. You could place a simple shell script into <code>/folder</code> like this one:</p>
<pre><code>~/folder$ cat extract-in-dir.sh
#!/bin/bash
DIRECTORY="${1%/*}"
TARFILE="${1##*/}"
cd $DIRECTORY
tar -xf $TARFILE
</code></pre>
<p>Then <code>chmod +x ./extract-in-dir.sh</code> and run it like this:</p>
<p><code>find . -type f -name \*tar -exec ./extract-in-dir.sh {} \;</code></p>

pandas table subsets giving invalid type comparison error <p>I am using pandas and want to select subsets of data and apply it to other columns.
e.g.</p>
<ul>
<li>if there is data in column A; & </li>
<li>if there is NO data in column B;</li>
<li>then, apply the data in column A to column D</li>
</ul>
<p>I have this working fine for now using <code>.isnull()</code> and <code>.notnull()</code>.
e.g. </p>
<pre><code>df = pd.DataFrame({'A' : pd.Series(np.random.randn(4)),
'B' : pd.Series(np.nan),
'C' : pd.Series(['yes','yes','no','maybe'])})
df['D']=''
df
Out[44]:
A B C D
0 0.516752 NaN yes
1 -0.513194 NaN yes
2 0.861617 NaN no
3 -0.026287 NaN maybe
# Now try the first conditional expression
df['D'][df['A'].notnull() & df['B'].isnull()] \
= df['A'][df['A'].notnull() & df['B'].isnull()]
df
Out[46]:
A B C D
0 0.516752 NaN yes 0.516752
1 -0.513194 NaN yes -0.513194
2 0.861617 NaN no 0.861617
3 -0.026287 NaN maybe -0.0262874
</code></pre>
<p>When one adds a third condition, to also check whether data in column C matches a particular string, we get the error:</p>
<pre><code>df['D'][df['A'].notnull() & df['B'].isnull() & df['C']=='yes'] \
= df['A'][df['A'].notnull() & df['B'].isnull() & df['C']=='yes']
File "C:\Anaconda2\Lib\site-packages\pandas\core\ops.py", line 763, in wrapper
res = na_op(values, other)
File "C:\Anaconda2\Lib\site-packages\pandas\core\ops.py", line 718, in na_op
raise TypeError("invalid type comparison")
TypeError: invalid type comparison
</code></pre>
<p>I have read that this occurs due to the different datatypes. And I can get it working if I change all the strings in column C for integers or booleans. We also know that string on its own would work, e.g. <code>df['A'][df['B']=='yes']</code> gives a boolean list.</p>
<p>So any ideas how/why this is not working when combining these datatypes in this conditional expression? What are the more pythonic ways to do what appears to be quite long-winded?</p>
<p>Thanks</p>
| <p>I think you need add parentheses <code>()</code> to conditions, also better is use <a href="http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.ix.html" rel="nofollow"><code>ix</code></a> for selecting column with boolean mask which can be assigned to variable <code>mask</code>:</p>
<pre><code>mask = (df['A'].notnull()) & (df['B'].isnull()) & (df['C']=='yes')
print (mask)
0 True
1 True
2 False
3 False
dtype: bool
df.ix[mask, 'D'] = df.ix[mask, 'A']
print (df)
A B C D
0 -0.681771 NaN yes -0.681771
1 -0.871787 NaN yes -0.871787
2 -0.805301 NaN no
3 1.264103 NaN maybe

Excluding the first 3 characters of a string using regex <p>Given any string in <strong>bash</strong>, e.g flaccid, I want to match all characters in the string but the first 3 (in this case I want to exclude "fla" and match only "ccid"). The regex also needs to work in <strong>sed</strong>.</p>
<p>I have tried positive look behind and the following regex expressions (as well as various other unsuccessful ones):</p>
<pre><code>^.{3}+([a-z,A-Z]+)
sed -r 's/(?<=^....)(.[A-Z]*)/,/g'
</code></pre>
<p>Google hasn't been very helpful as it only produce results like "get first 3 characters .." </p>
<p>Thanks in advance!</p>

<pre><code>str="flaccid"
echo "${str:3}"

<p>That will strip the first 3 characters out of your string. </p>

Relaunching PowerShell script as admin user <p>I have a quite a few computer systems which we need to deploy software. I've been using a simple method for detecting if a user is a local admin, then detecting if they have admin rights. If needed, the script relaunches with elevated privileges. If the user is not a local admin, the script relaunches using a different credentials (local admin). The script works great on systems which have a later version of PowerShell such as Windows 8 and Windows 10.</p>
<p>The problem is when the user is not an admin and the script is running on Windows 7. The script uses <code>$PSScriptPath</code> to relaunch the script. I don't think this works in earlier versions of PowerShell. So I tried setting <code>$PSScriptRoot</code> myself if the Major PowerShell version is < 3. The problem is then the script gets stuck in a loop of some sort where it just constantly opens and closes windows and then I have to kill it... If I don't define <code>$PSScriptRoot</code> I get the error</p>
<blockquote>
<p>Cannot bind argument to parameter 'Path' because it is null</p>
</blockquote>
<p>I assume this is because <code>$PSScriptRoot</code> isn't defined in PowerShell 2.0.</p>
<p>Here's an example of what I'm trying to do:</p>
<pre><code>#Check if PowerShell version is greater than 2. If not, set $PSSriptRoot.
if ($PSVersionTable.PSVersion.Major -lt 3) {
$PSScriptRoot = Split-Path -Parent $MyInvocation.MyCommand.Definition
}
#Check if the user is a local admin. If they are, set $LocalAdmin to $True.
$LocalAdmin = $false
if ((net localgroup administrators) -match ([System.Environment]::UserDomainName + "\\" + [System.Environment]::Username)) {
$LocalAdmin = $true
}
if ($LocalAdmin) {
#Check if the local admin needs to run the script as administrator
if (-not ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
$arguments = "& '" + $MyInvocation.MyCommand.Definition + "'"
Start-Process powershell -Verb runas -ArgumentList $arguments
break
}
} else {
#Not a local admin. Relaunch script as admin user.
Start-Process -Credential $credential (Join-Path $PSHome powershell.exe) -ArgumentList (@("-File",
(Join-Path $PSScriptRoot $MyInvocation.MyCommand)) + $args)
exit
}
</code></pre>
| <p>Don't re-define <a href="https://technet.microsoft.com/en-us/library/hh847768.aspx" rel="nofollow">automatic variables</a>. Nothing good will come of it.</p>
<p>Besides, why do you want to anyway? The only thing you use <code>$PSScriptRoot</code> for is to reconstruct the script path you already have. Just assign that path to a variable and use that in your script.</p>
<pre><code>$script = $MyInvocation.MyCommand.Definition
$ps = Join-Path $PSHome 'powershell.exe'
$isLocalAdmin = [bool]((net localgroup administrators) -match "$env:USERDOMAIN\\$env:USERNAME")
if ($isLocalAdmin) {
if (-not ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]'Administrator')) {
Start-Process $ps -Verb runas -ArgumentList "& '$script'"
exit
}
} else {

unable to iterate through for loop in windows batch script <p>Goal: Given string "CAR080 CAR085 CAR087" I need to iterate through all three cars and perform copying of files from the carname folder.</p>
<p>Need to copy files from individual car folders by looping through it.
Code:</p>
<pre><code> @echo off
set basesource=xyz\
set year=%date:~10,4%
set destination=C:\ARWISdata\year%year%
set tempDir=DATAARWIS\DATARP_%year%
set s= CAR080 CAR085 CAR087
set t=%s%
echo t:%t%
:loop
for /f "tokens=1*" %%a in ("%t%") do (
set temp1=%%a
set SLASH=\
echo basesource:%basesource%
echo temp1:%temp1%
set source=%basesource%%temp1%%SLASH%%tempDir%
echo source:%source%
IF EXIST %source% (echo source exists)
echo destination: %destination%
IF EXIST %destination% (echo destination exists) ELSE (mkdir C:\ARWISdata\year%year%)
for /f %%a in ('xcopy /S /E /Y /D "%source%" "%destination%" ') do (
echo.Copying file '%%a'
)
set t=%%b
)
if defined t goto :loop
but it is not giving me exact solution. As it needs to take first CAR080 and perform copy operation then in next cycle it should take CAR085 and perform copying and then finally CAR087.
Need the code urgently.
</code></pre>
| <p>Just simplify. This is equivalent to your code but without variables being set inside the <code>for</code> block, so you don't need delayed expansion (read <a href="http://stackoverflow.com/a/30177832/2861476">here</a>) to retrieve the value from the changed variables</p>
<pre class="lang-dos prettyprint-override"><code>@echo off

How to assign value to cell in excel VBA after clearing validation <p>So my vba function should assign different values to a cell based on a boolean input. True part works perfectly, however I'm getting stuck with the False statement. The True part assigns a drop down list to the cell, and the False part should erase it, and set its value to text "N/A". As soon as I'm trying to change the value of the cell (or any cells actually, with range("..").value command, the code faces an error.</p>
<p>Is there an other way around?
Thanks in advance!</p>
<pre><code>Function sema_list(rng As Range, sema As Boolean)
If sema = True Then
With rng.Validation
.Delete
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Operator:=xlBetween, Formula1:="=arrangement"
.IgnoreBlank = True
.InCellDropdown = True
.InputTitle = ""
.ErrorTitle = ""
.InputMessage = ""
.ErrorMessage = ""
.ShowInput = True
.ShowError = True
End With
End If
If sema = False Then
rng.Validation.Delete
rng.Value = "some text"
End If
sema_list = ""
End Function
</code></pre>
| <p>I guess you have to pass some range before assigning any value.
For eg:</p>
<pre><code>Range("A1:A10") = "some text"
</code></pre>
<p>or maybe something like this:</p>
<pre><code>Dim example As Range
Set example = Range("A1:A10")
example.Value = 8

Read regexes from file and avoid or undo escaping <p>I want to read regular expressions from a file, where each line contains a regex:</p>
<pre><code>lorem.*
dolor\S*
</code></pre>
<p>The following code is supposed to read each and append it to a list of regex strings:</p>
<pre><code>vocabulary=[]
with open(path, "r") as vocabularyFile:
for term in vocabularyFile:
term = term.rstrip()
vocabulary.append(term)
</code></pre>
<p>This code seems to escape the <code>\</code> special character in the file as <code>\\</code>. How can I either avoid escaping or unescape the string so that it can be worked with as if I wrote this?</p>
<pre><code>regex = r"dolor\S*"
</code></pre>
| <p>You are getting confused by <em>echoing the value</em>. The Python interpreter echoes values by printing the <code>repr()</code> function result, and this makes sure to escape any meta characters:</p>
<pre><code>>>> regex = r"dolor\S*"
>>> regex
'dolor\\S*'
</code></pre>
<p><code>regex</code> is still an 8 character string, not 9, and the single character at index 5 is a single backslash:</p>
<pre><code>>>> regex[4]
'r'
>>> regex[5]
'\\'
>>> regex[6]
'S'
</code></pre>
<p>Printing the string writes out all characters verbatim, so no escaping takes place:</p>
<pre><code>>>> print(regex)
dolor\S*
</code></pre>
<p>The same process is applied to the contents of containers, like a <code>list</code> or a <code>dict</code>:</p>
<pre><code>>>> container = [regex, 'foo\nbar']
>>> print(container)
['dolor\\S*', 'foo\nbar']
</code></pre>
<p>Note that I didn't echo there, I printed. <code>str(list_object)</code> produces the same output as <code>repr(list_object)</code> here.</p>
<p>If you were to print individual elements from the list, you get the same unescaped result again:</p>
<pre><code>>>> print(container[0])
dolor\S*
>>> print(container[1])
foo
bar
</code></pre>
<p>Note how the <code>\n</code> in the second element was written out as a newline now. It is for <em>that reason</em> that containers use <code>repr()</code> for contents; to make otherwise hard-to-detect or non-printable data visible.</p>
<p>In other words, your strings do <em>not</em> contain escaped strings here.</p>

Save JSON Decode to MySQL , PHP <p>Good Day Please can you assist I'm trying to update a mysql table with a JSON POST. The JSON output into a textfile fine but when I try and save it to the MySQL table then supplies an error:</p>
<blockquote>
<p>Undefined index: ptp.create</p>
</blockquote>
<p>The JSON Outputs the data as:</p>
<pre><code>{"ptp.create":["629","630"]}
$jsonString = file_get_contents("php://input");
$myFile = "NewFile.txt";
file_put_contents($myFile,$jsonString);
$data = json_decode($jsonString, true);
foreach ($data as $row){
$PTP = $row['ptp.create'];
$query_rsTable1 = "INSERT INTO test SET id = '$PTP'";
$rsTable1 = mysql_query($query_rsTable1, $int) or die(mysql_error());
}
</code></pre>
<p>I'm not very 100% confident in JSON yet, if you could please assist. </p>
| <p>Your <code>for</code> loop has already taken care of the <code>ptp.create</code> for you.</p>
<pre><code>foreach ($data as $ptp){
echo $ptp; // Will be 629, then 630
}
</code></pre>
<p>When you actually insert into your database, use prepared/parameterized queries with PDO or similar.</p>

Multiple find and replace in MS Word from a list in MS Excel <p>Hi I really hope you can help me as I've been trying to do this for a while with not a lot of luck. </p>
<p>I have a list in Excel, say, file 1 (say, A1 - B10, 2 columns of words - the words in column A are the ones to be replaced by the ones in column B).</p>
<p>I have a document in word, say, file 2, which I want to run the words in the excel file so that every appearance of any words which are in column A of the excel file is replaced by the corresponding words in column B.</p>
<p>I would really appreciate any help you could give me, thank you so much.</p>

Matlab random sampling <p>I am trying to exercise myself in Matlab. I am trying to select randomly two lines from a file named data.dat. </p>
<p>My data.dat file looks like this:</p>
<pre><code>12 4 6.1 7
14 4 8.4 62
7 56.1 75 98
9.7 54 12 35
2 4 8 7.8
</code></pre>
<p>To select 2 lines randomly from the data.dat here is how I am proceeding:</p>
<pre><code>close all;
clear all;
%----------------------%
% Choose random lines
%----------------------%
M = load('data.dat');
N=2; %number_of_lines
file_number = 2; %save each two lines in new file: selection_1, selection_2
</code></pre>
<p>Now I am saving the two selected lines in new files sequentially. </p>
<pre><code>for k = 1:file_number
i = randi(length(M),N);
B=M(i,:)
filename=['samples_',int2str(k),'_mc.dat']
save (filename, 'B', '-ascii')
clear B;
end
</code></pre>
<p>I don't know why but I have more than 2 lines in each new files. Could you please explain me where did I made a mistake.</p>
| <p>I think you are making a mistaking when you generate the random numbers, as indicated by GameOfThrows.</p>
<pre><code>i = randi(length(M),N); % gives you a matrix NxN of numbers
i = randi(length(M),[N,1]); % gives you a column of N numbers

GIF from external resource in page is not animating in apache wicket web application <p>I am using external images in my webaplication, everything wass fine until I wanted to add animated gif there, the gif loads, but it doesn't animate.</p>
<p>Java code:</p>
<pre><code> File sourceimage = new File("loading_img.gif");
try {
final BufferedDynamicImageResource r = new BufferedDynamicImageResource("GIF");
r.setImage(ImageIO.read(sourceimage));
add(new Image("gif", r));
} catch (Exception e) {
e.printStackTrace();
}
</code></pre>
<p>HTML:</p>
<pre><code> <img wicket:id="gif"/>
</code></pre>
<p>EDIT:</p>
<p>Tried martin-g suggestion, gif still doesn't animate</p>
<pre><code> try {
final BufferedDynamicImageResource r = new BufferedDynamicImageResource("GIF"){
@Override
protected void setResponseHeaders(AbstractResource.ResourceResponse data,
IResource.Attributes attributes){
super.setResponseHeaders(data, attributes);
data.setContentType("image/gif");
}
};
r.setImage(ImageIO.read(sourceimage));
add(new Image("gif", r));
} catch (Exception e) {
e.printStackTrace();
}
</code></pre>
| <p>The problem is that the content type is not automatically set.
You will need to override org.apache.wicket.request.resource.AbstractResource#setResponseHeaders() and set with via <code>resourceResponse.setContentType(String)</code>.</p>
<p>Maybe this should be done automatically by Wicket in org.apache.wicket.request.resource.DynamicImageResource, since it knows the format ("png", or "gif" as in your case). Please file a ticket in Wicket's JIRA for this improvement! Thanks!</p>

where t.name=k.name
and k.name ='Smith')
and then
delete from xx_2
where name ='Smith'
</code></pre>
<p>Is there anyway i can delete data from both these table together ? without creating two separate scripts ? </p>
| <p>There is no way to delete from many tables with a single statement, but the better question is why do you need to delete from all tables at the same time? It sounds to me like you don't fully understand how transactions work in Oracle.</p>
<p>Lets say you login and delete a row from table 1, but do not commit. As far as all other sessions are concerned, that row has not been deleted. If you open another connection and query for the row, it will still be there.</p>
<p>Then you delete from tables 2, 3 and then 4 in turn. You still have not committed the transaction, so all other sessions on the database can still see the deleted rows.</p>
<p>Then you commit.</p>
<p>All at the same time, the other sessions will no longer see the rows you deleted from the 4 tables, even though you did the deletes in 4 separate statements.</p>
<p>EDIT after edit in question:</p>
<p>You can define the foreign keys on the 3 child tables to "<code>ON DELETE CASCADE</code>". Then when you delete from the parent table, all associated rows from the 3 child tables are also deleted. </p>

t.time saving field as a string in ActiveRecord <p>I have a table with a field called <code>time_start</code>. Example: </p>
<pre><code>t.time :time_start
</code></pre>
<p>When I try to save the attribute, it saves it as a Hash-String. Example: </p>
<pre><code>params{
"time_start(1i)"=>"2016",
"time_start(2i)"=>"10",
"time_start(3i)"=>"12",
"time_start(4i)"=>"23",
"time_start(5i)"=>"59",
}
=> "{1=>2016, 2=>10, 3=>12, 4=>23, 5=>59}"
</code></pre>
<p>I cannot figure out why the attribute is saving a string instead of parsing into a Time obj. I have even tried a <code>rake db:rollback VERSION=123456546</code> to the migration just before it, but it still saves the value as a string after the <code>rake db:migrate</code>. I am not allowed to drop the table.</p>
| <p>Looking back through the commits, a Junior dev originally assigned the <code>time_start</code> field as a <code>string</code> data-type in table <code>B</code>. The solution was to grab the version number of the previous migration (table <code>A</code>), and run <code>rake db:migrate VERSION=213412341234</code>, then <code>rake db:migrate</code>. It is now saving correctly. </p>

HTML - How do I insert a <span></span> tag into each line of a <pre></pre> block without hard coding? <p>I was just trying to add line numbers at the beginning of source code using CSS.
I realized the effect I wanted, as follows:</p>
<p><a href="https://i.stack.imgur.com/A0P12.png" rel="nofollow"><img src="https://i.stack.imgur.com/A0P12.png" alt="Effect implemented"></a></p>
<p>However, the HTML code required continual use of <code><span>...</span></code> tags:</p>
<pre><code><pre class="code">
<span>var links = document.getElementsByClassName("link");</span>
<span>for(var i = 0; i &lt; links.length; i++){</span>
<span> links[i].onclick=function(){</span>
<span> alert(i+1);</span>
<span> };</span>
<span>}</span>
</pre>
</code></pre>
<p>With the <code>span</code> tags positioned at home/end of lines I can let the line numbers show as expected.
But I think there must be another better solution to prevent me adding all these <code>span</code> tags hard-coded, maybe using Javascript, or jQuery I don't mind but don't know how. Please help.</p>
<p>NOTE:<br>
My problem is not how to display line numbers when the <code><span></code> tags are already there. Instead, I wanted to know if the origin HTML code contains NO <code><span></code> tags, how can I automatically add them into the suitable places and so I can apply the CSS styles.</p>
| <p>This can be achieved by using CSS counters</p>
<p>This does not require any JavaScript (or jQuery) which means no need for each libraries or scripts and was introduced way back in CSS 2.1 so has great browser support across the board.</p>

SML Operator and operand don't agree in foldr <p>I'm working on an assignment where I have to write a function to get the length of a list. This is a trivial task, but I've come across something that I don't understand.</p>
<p>My simple code</p>
<pre><code>val len = foldr (fn(_, y) => y + 1) 0

value restriction are instantiated to dummy types (X1,X2,...)</p>

operator domain: ?.X1 list operand:

len (1 :: 2 :: 3 :: <exp> :: <exp>)

<p>I don't understand why this doesn't work. I do know some functional programming principles, and this should work, since its very simple partial application.</p>
<p>Of course I can make it work without partial application, like this</p>
<pre><code>fun len xs = foldr (fn(_, y) => y + 1) 0 xs
</code></pre>
<p>but I would like to understand why the first version doesn't work.</p>
| <p>This is an instance of the <a href="http://mlton.org/ValueRestriction" rel="nofollow">value restriction</a> rule application:</p>
<blockquote>
<p>In short, the value restriction says that generalization can only occur if the right-hand side of an expression is syntactically a value. </p>
</blockquote>
<p>Syntactically,</p>
<pre><code>foldr (fn(_, y) => y + 1) 0
</code></pre>
<p>is <em>not</em> a value, it's a function application, that's why it hasn't been assigned a <em>polymorphic</em> type. It has been instantiated with a dummy type, which has a very limited use, e.g. this works:</p>
<pre><code>len []
</code></pre>
<p>but in most cases <code>len</code> defined as <code>val</code> is useless.</p>
<p>This restriction exists to guarantee type safety in the presence of variable assignment (via references). More details can be found in the linked page.</p>

Echo option value with selected <p>Im tryin to fix when i press my search button. That the selected search from my option field remains selected. But at the moment it automaticly picks the first field of the options in my form.</p>
<p>First one is hardcoded and it works.</p>

</code></pre>
<p>This is how i get my $nickval</p>
<pre><code> $nickval = $_GET["int"];

How to get cursor position in an image with Matlab <p>I need to get the cursor position after a click on the image to obtain the corresponding pixel coordinates.
This is what I've done so far, which works as long as I click on the empty part of the figure (if I click on the image, the callback is not triggered).</p>
<pre><code>image(my_image);
set(gca, 'ButtonDownFcn', @click);
function click(o, event)
pt = get(o, 'CurrentPoint')
end
</code></pre>
<p>So afterward, I tried this one :</p>
<pre><code>image(my_image, 'ButtonDownFcn', @click);
function click(o, event)
pt = get(o, 'CurrentPoint')
end
</code></pre>
<p>But then, it tells me that the image class does not contain any field named 'CurrentPoint'. I suppose that I need to retrieve some kind of axes from the image, but I don't know how to do that.</p>
| <p>I've had to solve a similar problem before.</p>
<p>If you add an empty callback like the following the gui will track the cursor position</p>
<pre><code>function figure1_WindowButtonMotionFcn(~, ~, ~)
</code></pre>
<p>Then the figure1 handle should have a property <code>currentPoint</code> that will describe the position of the mouse. If you write a click event function that has access to the figure1 handle, something like this:</p>
<pre><code>image(my_image, 'ButtonwDownFcn', ...
@(hObject,eventdata)myGui('click',hObject,eventdata,guidata(hObject))
</code></pre>
<p>include the following line in it to access the mouse position</p>
<pre><code>mouseLocation = get(handles.figure1, 'currentPoint');
</code></pre>
<p>Then you'll have to translate the mouse position to pixel position using the position of the axes inside the figure.</p>

Convert json to Object List <p>I have the following String: </p>
<pre><code>String json = "[{\"id\": \"0\", \"ip\": \"123\", \"mac\": \"456\"}, {\"id\": \"1\", \"ip\": \"111\", \"mac\": \"222\"}]";
</code></pre>
<p>And a SlaveEntity Entity that has:</p>
<pre><code>public class SlaveEntity extends BaseEntity {
private String ip;
private String macAddress;
private String status;
@OneToMany(mappedBy="slave", targetEntity = PositionEntity.class, fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<PositionEntity> positions;
}
</code></pre>
<p>I am writing a method that takes the json and returns a List of SlaveEntity: </p>
<pre><code>public static List<SlaveEntity> JsonToSlaveEntity(String json) {
ObjectMapper objectMapper = new ObjectMapper();
List<SlaveEntity> obj = new ArrayList<SlaveEntity>();
try {
obj = objectMapper.readValue(json, List.class);
} catch (IOException e) {
e.printStackTrace();
}
return obj;
}
</code></pre>
<p>The problem is that the obj List results like this: </p>
<p><a href="https://i.stack.imgur.com/qOb1Z.png" rel="nofollow"><img src="https://i.stack.imgur.com/qOb1Z.png" alt="enter image description here"></a></p>
<p>But what I need the obj List to be is like this: </p>
<p><a href="https://i.stack.imgur.com/cx2xv.png" rel="nofollow"><img src="https://i.stack.imgur.com/cx2xv.png" alt="enter image description here"></a></p>
<p>So how can I get the needed list?</p>
| <p>You can convert the result to an object list, or you can pass in a type parameter rather than the <code>List</code> class.</p>
<pre><code>String jsonString = "[{\"id\": \"0\", \"ip\": \"123\", \"mac\": \"456\"}, {\"id\": \"1\", \"ip\": \"111\", \"mac\": \"222\"}]";
</code></pre>
<h3>With <code>Object</code></h3>
<pre><code>List<Object> items = objectMapper.readValue(
jsonString,
objectMapper.getTypeFactory().constructParametricType(List.class, Object.class)

</code></pre>
<h3>With <code>SlaveEntity</code></h3>
<pre><code>List<SlaveEntity> items = objectMapper.readValue(
jsonString,
objectMapper.getTypeFactory().constructCollectionType(List.class, SlaveEntity.class)
);

Java. The same objects with different hashes <p>I have two objects from database (in database it is same object), but they have different hashes:</p>
<pre><code>GroupType groupType = groupTypeDao.findById(3);
GroupType groupType1 = groupTypeDao.findById(3);
System.out.println(groupType);
System.out.println(groupType1);
</code></pre>
<p>I get this output:</p>
<pre><code>GroupType@6040
GroupType@6041
</code></pre>
<p>Why is that? Technology stack: Spring, JavaFX, Hibernate.</p>
<p>I have another project with Spring and Hibernate. Configuration files are identical in the two projects. Hibernate version is identical also. But in another project this produce same hashcodes.</p>
| <p>What you've printed are object references. They are indeed different if you created each reference by calling new.</p>
<p>You need to override equals, hashCode, and toString according to "Effective Java" to get the behavior you want.</p>

Create 4D upper diagonal array from 3D <p>Let's say that I have a <code>(x, y, z)</code> sized matrix. Now, I wish to create a new matrix of dimension <code>(x, y, i, i)</code>, where the <code>(i, i)</code> matrix is upper diagonal and constructed from the values on the <code>z</code>-dimension. Is there some easy way of doing this in <code>numpy</code> without using more than 1 for-loop (looping over x)? Thanks.</p>
<p><strong>EDIT</strong></p>
<pre><code>original = np.array([
[
[0, 1, 3],
[4, 5, 6]
],
[
[7, 8, 9],
[3, 2, 1]
],
])
new = np.array([
[
[
[0, 1],
[0, 3]
],
[
[4, 5],
[0, 6]
]
],
[
[
[7, 8],
[0, 9]
],
[
[3, 2],
[0, 1]
]
]
])
</code></pre>
<p>So, using the above we see that</p>
<pre><code>original[0, 0, :] = [0 1 3]
new[0, 0, :, :] = [[0 1]
[0 3]]
</code></pre>
| <p>Here's an approach using <code>boolean-indexing</code> -</p>
<pre><code>n = 2 # This would depend on a.shape[-1]
out = np.zeros(a.shape[:2] + (n,n,),dtype=a.dtype)
out[:,:,np.arange(n)[:,None] <= np.arange(n)] = a
</code></pre>
<p>Sample run -</p>
<pre><code>In [247]: a
Out[247]:
array([[[0, 1, 3],
[4, 5, 6]],
[[7, 8, 9],
[3, 2, 1]]])
In [248]: out
Out[248]:
array([[[[0, 1],
[0, 3]],
[[4, 5],
[0, 6]]],
[[[7, 8],
[0, 9]],
[[3, 2],
[0, 1]]]])
</code></pre>
<p>Another approach could be suggested using <code>subscripted-indexing</code> to replace the last step -</p>
<pre><code>r,c = np.triu_indices(n)
out[:,:,r,c] = a
</code></pre>
<p><strong>Note :</strong> As stated earlier, <code>n</code> would depend on <code>a.shape[-1]</code>. Here, we had <code>a.shape[-1]</code> as <code>3</code>, so <code>n</code> was <code>2</code>. If <code>a.shape[-1]</code> were <code>6</code>, <code>n</code> would be <code>3</code> and so on. The relationship is : <code>(n*(n+1))//2 == a.shape[-1]</code>.</p>

Add on-premise nodes to GKE <p>How do I add my on-premise node to my managed cluster?</p>
<p>I've tried doing "kubeadm join --token " with a default-token from the ui and the cluster endpoint as ip.</p>
| <p>You can add an on-prem node to your GKE cluster if you manually configure the kubelet (basically what kubeadm makes nice and easy). </p>
<p>Your cluster may not work as expected though unless you also create a VPN connection between the on-prem node and your cloud network where the rest of your nodes are running and also configure networking routes to map a node CIDR to your on-prem node. Otherwise, cross-pod networking will not work.</p>
<p>In addition, features like <code>kubectl exec</code> and <code>kubectl logs</code> likely won't work for any pods running on your on-prem node. </p>

Force WPF application to maximize on Windows startup <p>I have a WPF app that installed on Windows 10 Pro via ClickOnce and uses MahApps.Metro.</p>
<p>It is set to launch on Windows boot with a non-admin account that has no password. Tablet mode is enabled.</p>
<p>I want the application pop up full screen to create <strong>kiosk</strong>-like experience, however the <strong>app starts minimized</strong> when launching on boot. To clarify, the WindowState is Maximized, but Windows does not show it, instead it shows the start screen. It launches fullscreen maximized when launching manually.</p>
<p>Here is some code, however I guess this is more of a configuration problem than code problem:</p>
<p>This is how I set the launch on boot:</p>
<pre><code>RegistryKey rkApp = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run", true);
string startPath = Environment.GetFolderPath(Environment.SpecialFolder.Programs)
+ @"\Publisher\AppName.appref-ms";
rkApp.SetValue("AppName", startPath);
</code></pre>
<p>This is MainWindow.xaml</p>
<pre><code><Controls:MetroWindow x:Class="AppName.MainWindow"
IgnoreTaskbarOnMaximize="True" ShowTitleBar="False" WindowStyle="None" WindowState="Maximized">
...
</Controls:MetroWindow>
</code></pre>
| <p>You can do this in the MainWindow.xaml.cs by adding a windowstate of maximized.</p>
<pre><code>public MainWindow()
{
InitializeComponent();
this.WindowState = WindowState.Maximized;
}

Searching a PHP states array for beginning values <p>So I'm sure my solution is an easy one, but it just seems to escape me. I have a basic webpage where a user needs to be able to type in a beginning string of a state, hit search, and the page will output all of the states that begin with that string.</p>
<p>For example, if "co" was entered, then Colorado and Connecticut would be displayed, with the input case insensitive if possible. This inpt string should be able to be any length. I am using an array of $states to hold all 50 states that need to be searched. Below is what the basic form looks like.</p>
<pre><code><h1>Search States</h1>
<form method = "post" action = "states.php">
<p>Search:
<input type="text" name="search"></p>
<p><input type = "submit" value = "Submit"></p>
</form>
<?php
$states = array('Alabama',
'Alaska',
'Arizona',
'Arkansas',
'California',
'Colorado',
'Connecticut', etc, etc.
</code></pre>
<p>I assumed that some kind of regular expression search is what I am looking for, but I can't find how to produce one based off of input and using more than one character at times.</p>
<p>Thank you!</p>
| <p>Use this</p>
<pre><code>$arr = array();
$search_str = 'Co';
foreach($states as $key => $value){
$strlen = strlen($search_str);
if(strtolower(substr($value, 0, $strlen)) == strtolower($search_str)){
$arr[] = $value;
}
}
print_r($arr);

<p>I have a table around th echo data. I would be great if someone can give me a tip.</p>
| <p>First if tables have relation I suggest you to take the data in a single call with join.</p>
<pre><code>SELECT * FROM table_a a
LEFT JOIN tabl_b b ON a.user_name = b.user_name
WHERE a.state = '0'
</code></pre>
<p>Second for speeding up the things you can put INDEX on the two fields that you are using in the WHERE clause - state, user_name</p>
<pre><code>ALTER TABLE `table_a` ADD INDEX `state` (`state`)
ALTER TABLE `tabl_b` ADD INDEX `user_name` (`user_name`)

Create full VPC using salt stack and boto.vpc <p>I am able to create VPCs in AWS using salt states, using boto.vpc. But I also need to create create (in addition to the VPC itself) subnets, internet gateways, route tables based on the original VPC that I'm able to create.</p>
<p>So if the VPC definition looks like this: </p>
<pre><code> Create VPC:
boto_vpc.present:
- name: dlab-new
- cidr_block: 10.0.0.1/24
- dns_hostnames: True
- region: us-east-1
- keyid: keyid
- key: key
</code></pre>
<p>How can I refer to the original VPC in subsequent parts of the VPC config? Since I won't know the vpc_id of the VPC until it's created. Is there a variable I could use in subsequent definitions of subnets, IGWs and route tables using a variable?</p>
<pre><code>Create subnet:
boto_vpc.subnet_present:
- name: dlab-new-subnet
- vpc_id: ?????
- cidr_block: 10.0.0.1/24
- region: us-east-1
- keyid: keyid
- key: key
Create internet gateway:
boto_vpc.internet_gateway_present:
- name: dlab-igw
- vpc_name: ????
- keyid: keyid
- key: key
Create route:
boto_vpc.route_table_present:
- name: my_route_table
- vpc_id: ???
- routes:
- destination_cidr_block: 10.0.0.1/24
instance_id: i-123456
- subnet_names:
- dlab-new-subnet
- region: us-east-1
- profile:
keyid: keyid
key: key
</code></pre>
<p>Is there any way to use a variable in place of the - vpc_id value that would allow the definitions for subnet, IGW etc to get the name of the VPC generated by the Create VPC process?</p>
| <p>In order to get the VPC id of an existing VPC you can use <a href="https://docs.saltstack.com/en/latest/ref/modules/all/salt.modules.boto_vpc.html#salt.modules.boto_vpc.get_id" rel="nofollow">boto_vpc execution module</a></p>
<p>The first part of your state will create a VPC with the name <code>dlab-new</code> then you can test this from the command line
<code>salt minion_name boto_vpc.get_id dlab-new</code> which will return the VPC id if it finds a match.</p>
<p>Execution modules can be called within States like this:</p>
<pre><code>{% set vpc_id = salt.boto_vpc.get_id(name='dlab-new', region='us-east-1', keyid=keyid, key=key)['id'] %}
</code></pre>
<p>More info and examples <a href="https://docs.saltstack.com/en/latest/topics/jinja/index.html#jinja-in-states" rel="nofollow">JINJA IN STATES</a></p>
<ul>
<li><code>vpc_id</code> variable will hold the result which will be the VPC Id of <code>dlab-new</code> in this case and then you can pass it to the other states.</li>
<li>VPC name, region, aws keys and others can be set as variables at the top of your state for easier modification in the future instead of go through the whole state looking for them.</li>
<li>In order to get the vpc_id correctly you will need to create the VPC using the execution module because the jinja code will be evaluated first.</li>
</ul>
<p>The full state should be like this one</p>
<pre><code>{% set custom_vpc_name = 'dlab-new' %}
{% set custom_keyid = keyid %}
{% set custom_key = key %}
{% set custom_region = 'us-east-1' %}
{% set cidr_block = '10.0.0.1/24' %}
{% set instance_id = 'i-123456' %}
{% set create_vpc = salt.boto_vpc.create(vpc_name=custom_vpc_name,cidr_block=cidr_block,enable_dns_hostnames=True,region=custom_region,keyid=custom_keyid,key=custom_key) %}
#this line is using boto_vpc execution module and get_id function which will return the VPC id if a match is found and your vpc will be created as described above with the name 'dlab-new'
{% set vpc_id = salt.boto_vpc.get_id(name=custom_vpc_name, region=custom_region, keyid=custom_keyid, key=custom_key)['id'] %}
Create subnet:
boto_vpc.subnet_present:
- name: {{ custom_vpc_name }}-subnet
- vpc_id: {{ vpc_id }}
- cidr_block: {{ cidr_block }}
- region: {{ custom_region }}
- keyid: {{ custom_keyid }}
- key: {{ custom_key }}
Create internet gateway:
boto_vpc.internet_gateway_present:
- name: {{ custom_vpc_name }}-igw
- vpc_id: {{ vpc_id }} # I have changed this line from vpc_name into vpc_id, is that what you meant ?
- keyid: {{ custom_keyid }}
- key: {{ custom_key }}
Create route:
boto_vpc.route_table_present:
- name: my_route_table
- vpc_id: {{ vpc_id }}
- routes:
- destination_cidr_block: {{ cidr_block }}
instance_id: {{ instance_id }}
- subnet_names:
- {{ custom_vpc_name }}-subnet
- region: {{ custom_region }}
- profile:
keyid: {{ custom_keyid }}
key: {{ custom_key }}
</code></pre>
<p>This is untested code but I have done similar states like this using Salt.</p>

<p>This link is awesome: <a href="http://stackoverflow.com/questions/2616697/php-mysql-pagination">PHP & MySQL Pagination</a>
and it helped me a lot coding the method for pagination (I am using postgre, I changed a few things).</p>
<p>When I print each button for the pagination, I am using bootstrap's code:
<a href="http://www.w3schools.com/bootstrap/bootstrap_pagination.asp" rel="nofollow">http://www.w3schools.com/bootstrap/bootstrap_pagination.asp</a></p>
<pre><code><ul class=\"pagination pagination-sm\">$links</ul>
</code></pre>
<p>and:</p>
<pre><code>$links .= ($i != $page ) ? "<li><a href='$explode[0]$final$i'>$i</a><li> " : "";
</code></pre>
<p>for concatenating new strings to the $links variable(of course first this then echoing $links).</p>
<p>Note: I am using explode() because I get my URL and I fix the the <code>&page=</code></p>
<p><strong>My question is</strong>:</p>
<p>How do I shorten the number of buttons to show per page?</p>
<p>At the moment my situation is the one in the screenshot.
I'd love to get something like:</p>
<pre><code>[current][2][3][4][5]...[61][62]
</code></pre>
<p><strong>EDIT</strong>:</p>
<p>I changed the code to have the "current":</p>
<pre><code> if ($i != $page) {
$links.="<li><a href='$explode[0]$final$i'>$i</a><li>";
} else {
$links.="<li class=\"active\"><a href='#'>current</a><li>";
}
}
</code></pre>
<p><strong>EDIT</strong>:</p>
<p>added new image thanks to 1st solution (it is now black because I changed theme in the meantime).</p>
<p><strong>EDIT</strong>: adding the php code.</p>
<pre><code>$perPage = addslashes(strip_tags(@$_GET["perPage"]));
$page = addslashes(strip_tags(@$_GET['page'])) ?: '1';
$startAt = $perPage * ($page - 1);
SWITCH ($direction){
case "SENT":
$count = "SELECT count(*) as total, 'SENT' as direction FROM sent WHERE date >= '$fdate' AND date <= '$tdate' AND identification LIKE '%$identification%' ";
$query = "SELECT *,'SENT' as direction FROM sent WHERE date >= '$fdate' AND date <= '$tdate' AND identification LIKE '%$identification%' ";
break;
}
$res = pg_fetch_assoc(pg_query($conn, $count));
$total = ceil($res['total'] / $perPage);
if (empty($total1)) { $total1 = '0'; } else { $total1 = ceil($res['total1'] / $perPage); }
$totalPages = $total + $total1;
$links = "";
$absolute_url = full_url( $_SERVER );
for ($i = 1; $i <= $totalPages; $i++) {
$explode = explode("&page=", $absolute_url);
$final="&page=";
if ($i != $page) {
$links.="<li><a href='$explode[0]$final$i'>$i</a><li>";
} else {
$links.="<li class=\"active\"><a href='#'>current</a><li>";
}
}
$query .= "order by date DESC OFFSET '$startAt' LIMIT '$perPage' ";
$result = pg_query($conn, $query);
</code></pre>
<p><strong>EDIT:
Found the problem in the jquery:</strong>
it will not load, never, but when I call the function at the document=ready status, it will.</p>
<pre><code> <script>
$(document).ready(function(){
$('#paginateblock').css('margin-left','-110px');
});
</script>
</code></pre>
<p>I need this to work always, not only when the document is "ready", rather, at every click on 'paginateblock' or everytime I change page.</p>
<p>Anybody can help?</p>
<p><strong>SOLUTION #1:</strong>
Thanks to the help of <strong>S Gandhe</strong> that provided me his code, I'm copying it here with my correction.</p>
<pre><code>for ($i = 1; $i <= $totalPages; $i++) {
if($page >= 7){
$start = $page -4;
} else {
$start = $i;
}
$end = ($start + 7 < $totalPages)?($start + 7):$totalPages;
for ($start; $start <= $end ; $start++) {
$explode = explode("&page=", $absolute_url);
$final="&page=";
$css_class = ($page == $start ) ? "class='active'" : "";
$links .= "<li><a href='$explode[0]$final$start'>$start</a><li>";
}
}
</code></pre>
<p><strong>CSS:</strong> [the css for <code><li></code> did not change] </p>
<pre><code>#page-selection{
width:350px;
height:36px;
overflow:hidden;
}
</code></pre>
<p><strong>HTML/PHP</strong></p>
<pre><code><div id="page-selection"><?php echo "<ul class=\"pagination pagination-sm\">$links</ul>"; ?></div>
</code></pre>
<p><strong>SOLUTION #2 - FINAL:</strong>
I modified the code a bit more, the pagination buttons are inside a <code><div></code> and the content is aligned.
Plus, Page #1 and #lastpage are always shown.</p>
<p><strong>CODE:</strong></p>
<pre><code>for ($i = 1; $i <= $totalPages; $i++) {
if($page >= 4){
$start = $page -3;
} else {
$start = $i;
}
$end = ($start + 6 < $totalPages)?($start + 6):$totalPages;
for ($start; $start <= $end ; $start++) {
$explode = explode("&page=", $absolute_url);
$final="&page=";
$css_class = ($page == $start ) ? "class='active'" : "";
$links .= "<li><a href='$explode[0]$final$start'>$start</a></li>";
}
$firstpage = "<li><a href='$explode[0]$final'1><<</a></li>";
$lastpage = "<li><a href='$explode[0]$final$totalPages'>>></a></li>";
}
</code></pre>
<p><strong>HTML:</strong></p>
<pre><code> <div id="page-selector">
<div class="page-selector-field"><?php echo "<ul class=\"pagination pagination-sm\">$firstpage</ul>"; ?></div>
<div id="page-selection" class="page-selector-field"><?php echo "<ul class=\"pagination pagination-sm\">$links</ul>"; ?></div>
<div class="page-selector-field"><?php echo "<ul class=\"pagination pagination-sm\">$lastpage</ul>"; ?></div>
</div>
</code></pre>
<p><strong>CSS:</strong></p>
<pre><code>#page-selection{
width:344px;
height:36px;
overflow:hidden;
}
#page-selector{
width: 450px;
height:36px;
overflow:hidden;
/*margin: 0 auto; uncomment this if you want this bar centered */
}
.page-selector-field{
width:50px;
height:36px;
overflow:hidden;
float: left;
}
ul.pagination {
display: inline-block;
padding: 0;
margin: 0;
}
ul.pagination li {
display: inline;
width: 50px;
}
ul.pagination li a {
display: block;
width: 50px;
text-align:center;
float: left;
padding: 8px 16px;
text-decoration: none;
}

| <p>am not sure about the quality/performance of code, but you can do it multiple ways, 2 of them here.
I actually started using lazy load and auto loading of pages when scroll rather page numbers, so I don't have the code.</p>
<p>1) JS/CSS:You can create a fix width div for page numbers and scroll to current page using current page number * each div width.
let's say your current page is 54 and each page number is taking 50px. you will set the margin left to -2000px something.</p>
<pre><code>$('#paginateblock').css('margin-left','-110px');
</code></pre>
<p><a href="https://jsfiddle.net/66wy0t19/3/" rel="nofollow">https://jsfiddle.net/66wy0t19/3/</a></p>
<p>2) PHP : as you said you have the links in array. you can use array_splice to get just the 10 links based on current page number. so if it's 54. you will may be spice it from 50-60 for showing 10.</p>
<ul>
<li>now you will need 2 buttons. one to move the page numbers div and second to get to Next page (like 4th from 3rd).</li>
</ul>
<p><strong>Update:</strong>
Couldn't find the js code, but here is some code based on php solution.
one minor advantage is you won't print all 100 items on page rather just print 5 links.</p>
<pre><code>echo "<ul class='pagination wrap'>";
if ($this->pageNumber - 1) {
echo "<li ><a href='{$this->url}/page_" . ($this->pageNumber - 1) . "/' {$ajax_request}><<</a></li>";
}
$start =($this->pageNumber > 5)?$this->pageNumber -4:1;
$end = ($i + 5 < $this->total_pages)?($start+5):$this->total_pages;
for ($start; $start <= $end ; $start++) {
echo "<li {$css_class}><a href='{$this->url}/page_{$i}/' {$ajax_request} >{$i}</a></li>";
}
if ($this->total_pages - $this->pageNumber > 1) {
echo "<li ><a href='{$this->url}/page_" . ($this->pageNumber + 1) . "/' {$ajax_request}>>></a></li>";
}
echo "</ul>";[![the output looks like this. ofcourse with classes. but i use bootstrap too.][1]][1]

<p><strong>Update 2:</strong>
Assuming each page number is taking 50px. this should work. </p>
<pre><code>var currentPage =27;
var paginateBlockMargin = (Math.ceil(currentPage/2) * 100)-100;
$('#paginateblock').css('margin-left', '-'+paginateBlockMargin+'px');

<p>This is the PHP code using your variables. You would need to replace your for loop with following. Prefer PHP code, as you will still need a lot of consideration in above JS. I wish I could find that JS code I had. sad.</p>
<pre><code>if($page > 5){
$start = $page -4;
}
$end = ($start + 5 < $totalPages)?($start + 5):$totalPages;
for ($start; $start <= $end ; $start++) {
$explode = explode("&page=", $absolute_url);
$final="&page=";
$css_class = ($page == $start ) ? "class='active'" : "";
$links .= "<li><a href='$explode[0]$final$start'>$start</a><li>";
}

Python handle 'NoneType' object has no attribute 'find_all' error with if else statement <p>I am using beautifulsoup4 to grab stock data and send to a spreadsheet in python. The problem I am having is that I cannot get my loop to skip over attributes that return None. So what I am needing is the code to add null values to rows where
attribute would return none.</p>
<pre><code>//my dictionay for storing data
data = {
'Fiscal Quarter End' : [],
'Date Reported' : [],
'Earnings Per Share' : [],
'Consensus EPS* Forecast' : [],
'% Surprise' : []
}
url = ""
html = requests.get(url)
data = html.text
soup = bs4.BeautifulSoup(data)
table = soup.find("div", class_="genTable")
for row in table.find_all('tr')[1:]:
if row.has_attr('tr'):
cols = row.find_all("td")
data['Fiscal Quarter End'].append( cols[0].get_text() )
data['Date Reported'].append( cols[1].get_text() )
data['Earnings Per Share'].append( cols[2].get_text() )
data['Consensus EPS* Forecast'].append( cols[3].get_text() )
data['% Surprise'].append( cols[4].get_text() )
else:
//where i need to add in the empty 'n/a' values
data['Fiscal Quarter End'].append()
data['Date Reported'].append()
data['Earnings Per Share'].append()
data['Consensus EPS* Forecast'].append()
data['% Surprise'].append()
</code></pre>
| <p>You have used the <code>data</code> variable for two different things. The second usage overwrote your dictionary. It is simpler to just use <code>html.text</code> in the call to <code>soup.find()</code>. Try the following:</p>
<pre><code>import requests
import bs4
# My dictionary for storing data
data = {
'Fiscal Quarter End' : [],
'Date Reported' : [],
'Earnings Per Share' : [],
'Consensus EPS* Forecast' : [],
'% Surprise' : []
}
empty = 'n/a'
url = ""
html = requests.get(url)
soup = bs4.BeautifulSoup(html.text, "html.parser")
table = soup.find("div", class_="genTable")
rows = []
if table:
rows = table.find_all('tr')[1:]
for row in rows:
cols = row.find_all("td")
data['Fiscal Quarter End'].append(cols[0].get_text())
data['Date Reported'].append(cols[1].get_text())
data['Earnings Per Share'].append(cols[2].get_text())
data['Consensus EPS* Forecast'].append(cols[3].get_text())
data['% Surprise'].append(cols[4].get_text())
if len(rows) == 0:
# Add in the empty 'n/a' values if no columns found
data['Fiscal Quarter End'].append(empty)
data['Date Reported'].append(empty)
data['Earnings Per Share'].append(empty)
data['Consensus EPS* Forecast'].append(empty)
data['% Surprise'].append(empty)
</code></pre>
<p>In the event the <code>table</code> or <code>rows</code> was empty, <code>data</code> would hold the following:</p>
<pre><code>{'Date Reported': ['n/a'], 'Earnings Per Share': ['n/a'], '% Surprise': ['n/a'], 'Consensus EPS* Forecast': ['n/a'], 'Fiscal Quarter End': ['n/a']}
</code></pre>

Why can't I commit changes in a conflicted state? <p>As we all know, merging branches in subversion (or any other revision control system for that matter) every so often results in conflicts. Somtimes these conflicts can be very complicated to resolve. Yet you are required to do so before committing the changes to the repository. </p>
<p>As the merge itself obviously will apply a set of changes, any modifications to resolve the conflicts will be applied on top of these. In the end it is impossible to separate the changes from the automatic merge from the manual modifications applied to resolve the conflicts.</p>
<p>It is not uncommon that issues are introduced when merging, not only due the challenge of integration itself, but from incorrect decisions when resolving merge conflicts. It would be easier to track these issues down fast if the decisions made when resolving any conflicts were clearly visible in a separate commit. It would also be easier to have a colleague review what you have done to resolve the conflicts.</p>
<p>This would be possible if committing changes in a conflicted state would be allowed. The automatic merge including conflicts could be committed first and conflict resolution afterwards.</p>
<p>Obviously you could argue that it is undesired to have a repository in a conflicted state, but you could always have the client access a last-unconflicted-revision. I would rather have a repository in a conflicted state every once in a while, instead of a repository broken by incorrect merge resolution.</p>
<p>Are there any reasons why can't I commit changes in a conflicted state?</p>
<p>Optional: Am I missing some subversion magic, are there tools to find out what decisions were made to resolve conflicts?</p>
<p>Optional: Does git or any other revision handling system handle this better than subversion?</p>
| <p>Think about what it would <em>mean</em> for your repository to be in a conflicted state. What that means is that there is more than one possible correct latest version of the code, which means that you have forked the repository. Source control systems already have means by which a repository can be forked.</p>
<p>If you really don't know what the solution to the merge conflict is, you are forking your code, so you should do a proper fork and not try to implement some sort of pseudo or quasi-fork into your source control system!</p>

Where are the ASP.NET core symbols hosted? <p>Have the .NET / ASP.NET core symbols been hosted anywhere yet? They would be helpful in debugging and learning.</p>
| <p>To debug Asp.Net Core, I followed the article sbouaked is mentionning, got the source from Git, and it's working perfectly. Didn't find a way to get only the symbols.</p>

openpyxl read formula value without changing formula <p>I want to read the formula value in an xlsx file, write the value in another cell and store the xlsx file.</p>
<p>I'm using the data_only mode</p>
<pre><code>excelDoc = openpyxl.load_workbook(clientFile, data_only=True)
</code></pre>
<p>to read the formula value. But when I save the file all formulas are overriden by their values.</p>
<p>How can I prevent that?</p>
| <p>You can't. You can either have the values or the formulae.</p>
