What if you do this (as was suggested earlier):
new_time = dfs['XYF']['TimeUS'].astype(float)
new_time_F = new_time / 1000000
You could use KEY
unique key (combination of the data) that changes with props, and that component will be rerendered with updated props.
Even better use implicit remoting to use a module from another Machine!
$s = New-PSSession Server-Name
Invoke-Command -Session $s -ScriptBlock {Import-Module ActiveDirectory}
Import-PSSession -Session $s -Module ActiveDirectory -Prefix REM
This will allow you to use the module off a remote PC for as long as the PSSession is connected.

In my case the underlying system account through which the package was running was locked out. Once we got the system account unlocked and reran the package, it executed successfully. The developer said that he got to know of this while debugging wherein he directly tried to connect to the server and check the status of the connection.
You are trying to load a XIB named DetailViewController
, but no such XIB exists or it's not member of your current target.
I still believe its to do with the props file not being located by spring. Do a quick test by passing the params as jvm params. i.e -Didm.url=....
The following signature will do:
List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);
Spring Data JPA supports a large number of keywords to build a query. IN
and AND
are among them.
This may be helpful to you:
<script type="text/javascript">
function Showalert() {
alert('Profile not parsed!!');
window.parent.parent.parent.location.reload();
}
function ImportingDone() {
alert('Importing done successfull.!');
window.parent.parent.parent.location.reload();
}
</script>
if (SelectedRowCount == 0)
{
ScriptManager.RegisterStartupScript(this, GetType(), "displayalertmessage", "Showalert();", true);
}
else
{
ScriptManager.RegisterStartupScript(this, GetType(), "importingdone", "ImportingDone();", true);
}
To find distinct in field_1
in collection but we want some WHERE
condition too than we can do like following :
db.your_collection_name.distinct('field_1', {WHERE condition here and it should return a document})
So, find number distinct names
from a collection where age > 25 will be like :
db.your_collection_name.distinct('names', {'age': {"$gt": 25}})
Hope it helps!
You can also set a default value for the variable, so you don't need to use two "[", which amounts to two processes ("[" is actually a program) instead of one.
It goes by this syntax: ${VARIABLE:-default}.
The whole thing has to be thought in such a way that this "default" value is something distinct from a "valid" value/content.
If that's not possible for some reason you probably need to add a step like checking if there's a value at all, along the lines of "if [ -z $VARIABLE ] ; then echo "the variable needs to be filled"", or "if [ ! -z $VARIABLE ] ; then #everything is fine, proceed with the rest of the script".
Get the time in milliseconds, minus your minutes in milliseconds and convert it to Date. Here you need to objectify one!!!
int minutes = 60;
long currentDateTime = System.currentTimeMillis();
Date currentDate = new Date(currentDateTime - minutes*60*1000);
System.out.println(currentDate);
Use:
git reset HEAD^
That does a "mixed" reset by default, which will do what you asked; put foo.java in unstaged, removing the most recent commit.
I prefer to use the ngModel and ngChange directives when dealing with checkboxes. ngModel allows you to bind the checked/unchecked state of the checkbox to a property on the entity:
<input type="checkbox" ng-model="entity.isChecked">
Whenever the user checks or unchecks the checkbox the entity.isChecked
value will change too.
If this is all you need then you don't even need the ngClick or ngChange directives. Since you have the "Check All" checkbox, you obviously need to do more than just set the value of the property when someone checks a checkbox.
When using ngModel with a checkbox, it's best to use ngChange rather than ngClick for handling checked and unchecked events. ngChange is made for just this kind of scenario. It makes use of the ngModelController for data-binding (it adds a listener to the ngModelController's $viewChangeListeners
array. The listeners in this array get called after the model value has been set, avoiding this problem).
<input type="checkbox" ng-model="entity.isChecked" ng-change="selectEntity()">
... and in the controller ...
var model = {};
$scope.model = model;
// This property is bound to the checkbox in the table header
model.allItemsSelected = false;
// Fired when an entity in the table is checked
$scope.selectEntity = function () {
// If any entity is not checked, then uncheck the "allItemsSelected" checkbox
for (var i = 0; i < model.entities.length; i++) {
if (!model.entities[i].isChecked) {
model.allItemsSelected = false;
return;
}
}
// ... otherwise ensure that the "allItemsSelected" checkbox is checked
model.allItemsSelected = true;
};
Similarly, the "Check All" checkbox in the header:
<th>
<input type="checkbox" ng-model="model.allItemsSelected" ng-change="selectAll()">
</th>
... and ...
// Fired when the checkbox in the table header is checked
$scope.selectAll = function () {
// Loop through all the entities and set their isChecked property
for (var i = 0; i < model.entities.length; i++) {
model.entities[i].isChecked = model.allItemsSelected;
}
};
CSS
What is the best way to... add a CSS class to the
<tr>
containing the entity to reflect its selected state?
If you use the ngModel approach for the data-binding, all you need to do is add the ngClass directive to the <tr>
element to dynamically add or remove the class whenever the entity property changes:
<tr ng-repeat="entity in model.entities" ng-class="{selected: entity.isChecked}">

Now, there is gcc-4.9 available for Ubuntu/precise.
Create a group of compiler alternatives where the distro compiler has a higher priority:
root$ VER=4.6 ; PRIO=60
root$ update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-$VER $PRIO --slave /usr/bin/g++ g++ /usr/bin/g++-$VER
root$ update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-$VER $PRIO
root$ VER=4.9 ; PRIO=40
root$ update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-$VER $PRIO --slave /usr/bin/g++ g++ /usr/bin/g++-$VER
root$ update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-$VER $PRIO
NOTE: g++ version is changed automatically with a gcc version switch. cpp-bin has to be done separately as there exists a "cpp" master alternative.
List available compiler alternatives:
root$ update-alternatives --list gcc
root$ update-alternatives --list cpp-bin
To select manually version 4.9 of gcc, g++ and cpp, do:
root$ update-alternatives --config gcc
root$ update-alternatives --config cpp-bin
Check compiler versions:
root$ for i in gcc g++ cpp ; do $i --version ; done
Restore distro compiler settings (here: back to v4.6):
root$ update-alternatives --auto gcc
root$ update-alternatives --auto cpp-bin
@Tom Esterez's answer, but updated to use view.measure() properly per Android getMeasuredHeight returns wrong values !
// http://easings.net/
Interpolator easeInOutQuart = PathInterpolatorCompat.create(0.77f, 0f, 0.175f, 1f);
public static Animation expand(final View view) {
int matchParentMeasureSpec = View.MeasureSpec.makeMeasureSpec(((View) view.getParent()).getWidth(), View.MeasureSpec.EXACTLY);
int wrapContentMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
view.measure(matchParentMeasureSpec, wrapContentMeasureSpec);
final int targetHeight = view.getMeasuredHeight();
// Older versions of android (pre API 21) cancel animations for views with a height of 0 so use 1 instead.
view.getLayoutParams().height = 1;
view.setVisibility(View.VISIBLE);
Animation animation = new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
view.getLayoutParams().height = interpolatedTime == 1
? ViewGroup.LayoutParams.WRAP_CONTENT
: (int) (targetHeight * interpolatedTime);
view.requestLayout();
}
@Override
public boolean willChangeBounds() {
return true;
}
};
animation.setInterpolator(easeInOutQuart);
animation.setDuration(computeDurationFromHeight(view));

JS
Create an external JavaScript file (i.e. mymap.js) with the following code
google.maps.visualRefresh = true; //Optional
var respMap;
function mymapini() {
var mapPos = new google.maps.LatLng(-0.172175,1.5); //Set the coordinates
var mapOpts = {
zoom: 10, //You can change this according your needs
disableDefaultUI: true, //Disabling UI Controls (Optional)
center: mapPos, //Center the map according coordinates
mapTypeId: google.maps.MapTypeId.ROADMAP
};
respMap = new google.maps.Map(document.getElementById('mymap'),
mapOpts);
var mapMarker = new google.maps.Marker({
position: mapPos,
map: respMap,
title: 'You can put any title'
});
//This centers automatically to the marker even if you resize your window
google.maps.event.addListener(respMap, 'idle', function() {
window.setTimeout(function() {
respMap.panTo(mapPos.getPosition());
}, 250);
});
}
google.maps.event.addDomListener(window, 'load', mymapini);
$("#modalOpen").click(function(){ //Use it like <a href="#" id="modalOpen"...
$("#myModal").show(); //ID from the Modal <div id="myModal">...
google.maps.event.trigger(respMap, 'resize');
});
HTML
Add the following code before the tag:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script src="js/mymap.js"></script>
Add this to the modal code:
<div id="mymap"></div>
CSS
Add this to your stylesheet:
#mymap { margin: 0; padding: 0; width:100%; height: 400px;}
var jsonStringNoQuotes = [{"Id":"10","Name":"Matt"},{"Id":"1","Name":"Rock"}];
it will create json object. no need to parse.
jsonStringQuotes = "'" + jsonStringNoQuotes + "'";
will return '[object]'
thats why it(below) is causing error
var myData = JSON.parse(jsonStringQuotes);
You have to use bracket notation:
var obj = {};
obj[a[i]] = 0;
x.push(obj);
The result will be:
x = [{left: 0}, {top: 0}];
Maybe instead of an array of objects, you just want one object with two properties:
var x = {};
and
x[a[i]] = 0;
This will result in x = {left: 0, top: 0}
.
As stated already, you can operate on Time
objects as if they were numeric (or floating point) values. These operations result in second resolution which can easily be converted.
For example:
def time_diff_milli(start, finish)
(finish - start) * 1000.0
end
t1 = Time.now
# arbitrary elapsed time
t2 = Time.now
msecs = time_diff_milli t1, t2
You will need to decide whether to truncate that or not.
Once java-8 is out (March 2014) you'll be able to use streams:
int sum = IntStream.of(a).sum();
or even
int sum = IntStream.of(a).parallel().sum();
There is no need to involve any image classes, you can simply call WebClient.DownloadFile
:
string localFilename = @"c:\localpath\tofile.jpg";
using(WebClient client = new WebClient())
{
client.DownloadFile("http://www.example.com/image.jpg", localFilename);
}
Update
Since you will want to check whether the file exists and download the file if it does, it's better to do this within the same request. So here is a method that will do that:
private static void DownloadRemoteImageFile(string uri, string fileName)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
// Check that the remote file was found. The ContentType
// check is performed since a request for a non-existent
// image file might be redirected to a 404-page, which would
// yield the StatusCode "OK", even though the image was not
// found.
if ((response.StatusCode == HttpStatusCode.OK ||
response.StatusCode == HttpStatusCode.Moved ||
response.StatusCode == HttpStatusCode.Redirect) &&
response.ContentType.StartsWith("image",StringComparison.OrdinalIgnoreCase))
{
// if the remote file was found, download oit
using (Stream inputStream = response.GetResponseStream())
using (Stream outputStream = File.OpenWrite(fileName))
{
byte[] buffer = new byte[4096];
int bytesRead;
do
{
bytesRead = inputStream.Read(buffer, 0, buffer.Length);
outputStream.Write(buffer, 0, bytesRead);
} while (bytesRead != 0);
}
}
}
In brief, it makes a request for the file, verifies that the response code is one of OK
, Moved
or Redirect
and also that the ContentType
is an image. If those conditions are true, the file is downloaded.
Another issue that you might run into if you're running RHEL (I ran into it) is that there is a default welcome page configured with the httpd package that will override your settings, even if you put Options Indexes. The file is in /etc/httpd/conf.d/welcome.conf. See the following link for more info: http://wpapi.com/solved-issue-directory-index-forbidden-by-options-directive/
I think you are forgetting about the border. Having a one-pixel-wide border on the Div will take away two pixels of total length. Therefore it will appear as though the div is two pixels shorter than it actually is.
If you wrote the console application you can make it hidden by default.
Create a new console app then then change the "Output Type" type to "Windows Application" (done in the project properties)
All three represent mapping from unique keys to values, and therefore implement the Map interface.
HashMap is a map based on hashing of the keys. It supports O(1) get/put operations. Keys must have consistent implementations of hashCode()
and equals()
for this to work.
LinkedHashMap is very similar to HashMap, but it adds awareness to the order at which items are added (or accessed), so the iteration order is the same as insertion order (or access order, depending on construction parameters).
TreeMap is a tree based mapping. Its put/get operations take O(log n) time. It requires items to have some comparison mechanism, either with Comparable or Comparator. The iteration order is determined by this mechanism.
use box-shadow
with no horizontal offset.
http://www.css3.info/preview/box-shadow/
eg.
div {_x000D_
-webkit-box-shadow: 0 10px 5px #888888;_x000D_
-moz-box-shadow: 0 10px 5px #888888;_x000D_
box-shadow: 0 10px 5px #888888;_x000D_
}
_x000D_
<div>wefwefwef</div>
_x000D_
There will be a slight shadow on the sides with a large blur radius (5px in above example)
Best way in my opinion.
$.fn.findByContentText = function (text) {
return $(this).contents().filter(function () {
return $(this).text().trim() == text.trim();
});
};
Simple Solution: Goto your docker folder in the system and delete .raw file or docker archive with large size.
Hope to add more value by providing the normal formatter including the year, month and day with the time. You can use this formatter for more than just a year

This last method, it could also reorganize the array order depending the value of keys. Sometimes this could be the desired behaviour (sometimes don't). But the advantage now is that the values are indexed on the correct array slot, essential and trivial to do searches on it.
Finally (not part of the original question, but for completeness), if you need to easy search using the key or the value, but you don't want sparse arrays, no duplicates and no reordering without the need to convert to numeric keys (even can access very complex keys), then array (or object) is not what you need. I will recommend Map
instead:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map
let r=new Map(Object.entries(obj));
r.get("4"); //6
r.has(8); //true
it's in <algorithm>
and called std::find
.

First of all, since Spring doesn't do persistence itself, it cannot specify what readOnly
should exactly mean. This attribute is only a hint to the provider, the behavior depends on, in this case, Hibernate.
If you specify readOnly
as true
, the flush mode will be set as FlushMode.NEVER
in the current Hibernate Session preventing the session from committing the transaction.
Furthermore, setReadOnly(true) will be called on the JDBC Connection, which is also a hint to the underlying database. If your database supports it (most likely it does), this has basically the same effect as FlushMode.NEVER
, but it's stronger since you cannot even flush manually.
Now let's see how transaction propagation works.
If you don't explicitly set readOnly
to true
, you will have read/write transactions. Depending on the transaction attributes (like REQUIRES_NEW
), sometimes your transaction is suspended at some point, a new one is started and eventually committed, and after that the first transaction is resumed.
OK, we're almost there. Let's see what brings readOnly
into this scenario.
If a method in a read/write transaction calls a method that requires a readOnly transaction, the first one should be suspended, because otherwise a flush/commit would happen at the end of the second method.
Conversely, if you call a method from within a readOnly transaction that requires read/write, again, the first one will be suspended, since it cannot be flushed/committed, and the second method needs that.
In the readOnly-to-readOnly, and the read/write-to-read/write cases the outer transaction doesn't need to be suspended (unless you specify propagation otherwise, obviously).
Here's my more robust version of Gor's answer (using fragments.size()is unreliable due to size not being decremented after fragment is popped)
getFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
@Override
public void onBackStackChanged() {
if (getFragmentManager() != null) {
Fragment topFrag = NavigationHelper.getCurrentTopFragment(getFragmentManager());
if (topFrag != null) {
if (topFrag instanceof YourFragment) {
//This fragment is being shown.
} else {
//Navigating away from this fragment.
}
}
}
}
});
And the 'getCurrentTopFragment' method:
public static Fragment getCurrentTopFragment(FragmentManager fm) {
int stackCount = fm.getBackStackEntryCount();
if (stackCount > 0) {
FragmentManager.BackStackEntry backEntry = fm.getBackStackEntryAt(stackCount-1);
return fm.findFragmentByTag(backEntry.getName());
} else {
List<Fragment> fragments = fm.getFragments();
if (fragments != null && fragments.size()>0) {
for (Fragment f: fragments) {
if (f != null && !f.isHidden()) {
return f;
}
}
}
}
return null;
}
Use below one,
map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));
You can use java8 + rxjava.
//import java.util.stream.IntStream;
//import rx.Observable;
IntStream intStream = IntStream.range(1,10000000);
Observable.from(() -> intStream.iterator())
.takeWhile(n -> n < 10)
.forEach(n-> System.out.println(n));
Probably something like:
ArrayList<DataPoint> myList = new ArrayList<DataPoint>();
//Fill up myList with your Data Points
//Traversal
for(DataPoint myPoint : myList) {
if(myPoint.getName() != null && myPoint.getName().equals("Michael Hoffmann")) {
//Process data do whatever you want
System.out.println("Found it!");
}
}
You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.
Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.
Express 4.x
To get a URL parameter's value, use req.params
app.get('/p/:tagId', function(req, res) {
res.send("tagId is set to " + req.params.tagId);
});
// GET /p/5
// tagId is set to 5
If you want to get a query parameter ?tagId=5
, then use req.query
app.get('/p', function(req, res) {
res.send("tagId is set to " + req.query.tagId);
});
// GET /p?tagId=5
// tagId is set to 5
Express 3.x

app.get('/p/:tagId', function(req, res) {
res.send("tagId is set to " + req.param("tagId"));

// GET /p/5
// tagId is set to 5
Query parameter
app.get('/p', function(req, res) {
res.send("tagId is set to " + req.query("tagId"));

To use rgba
background in IE there is a fallback.
We have to use filter property. that uses ARGB
background:none;
-ms-filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#33ffffff,endColorstr=#33ffffff);
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#33ffffff,endColorstr=#33ffffff);
zoom: 1;
this is fallback for rgba(255, 255, 255, 0.2)
Change #33ffffff
according to yours.
ARGB
for RGBA
Do you mean this:
if (newStr4.startsWith("Mon") || newStr4.startsWith("Tues") || ...)
Or you could use regular expression:
if (newStr4.matches("(Mon|Tues|Wed|Thurs|Fri).*"))

All the answers are beneficial to gather the information to write efficient code. However, I have written a small Python script to optimize for various cases. It will be the best case if the provided array is sorted. If one searches the index of the nearest point of a specified value, then bisect
module is the most time efficient. When one search the indices correspond to an array, the numpy searchsorted
is most efficient.
import numpy as np
import bisect
xarr = np.random.rand(int(1e7))
srt_ind = xarr.argsort()
xar = xarr.copy()[srt_ind]
xlist = xar.tolist()
bisect.bisect_left(xlist, 0.3)
In [63]: %time bisect.bisect_left(xlist, 0.3) CPU times: user 0 ns, sys: 0 ns, total: 0 ns Wall time: 22.2 µs
np.searchsorted(xar, 0.3, side="left")
In [64]: %time np.searchsorted(xar, 0.3, side="left") CPU times: user 0 ns, sys: 0 ns, total: 0 ns Wall time: 98.9 µs
randpts = np.random.rand(1000)
np.searchsorted(xar, randpts, side="left")
%time np.searchsorted(xar, randpts, side="left") CPU times: user 4 ms, sys: 0 ns, total: 4 ms Wall time: 1.2 ms
If we follow the multiplicative rule, then numpy should take ~100 ms which implies ~83X faster.
The same thing happened to me. Here is what I did in order to get it successfully installed. I downloaded KB2999226 update from Microsofts website here: https://www.microsoft.com/en-us/download/details.aspx?id=49093
After installing this package, I started the installation process again. That worked for me.
You are encoding the form incorrectly. You should only encode the values:
StringBuilder postData = new StringBuilder();
postData.Append("username=" + HttpUtility.UrlEncode(uname) + "&");
postData.Append("password=" + HttpUtility.UrlEncode(pword) + "&");
postData.Append("url_success=" + HttpUtility.UrlEncode(urlSuccess) + "&");
postData.Append("url_failed=" + HttpUtility.UrlEncode(urlFailed));
edit
I was incorrect. According to RFC1866 section 8.2.1 both names and values should be encoded.
But for the given example, the names do not have any characters that needs to be encoded, so in this case my code example is correct ;)
The code in the question is still incorrect as it would encode the equal sign which is the reason to why the web server cannot decode it.
A more proper way would have been:
StringBuilder postData = new StringBuilder();
postData.AppendUrlEncoded("username", uname);
postData.AppendUrlEncoded("password", pword);
postData.AppendUrlEncoded("url_success", urlSuccess);
postData.AppendUrlEncoded("url_failed", urlFailed);
//in an extension class
public static void AppendUrlEncoded(this StringBuilder sb, string name, string value)
{
if (sb.Length != 0)
sb.Append("&");
sb.Append(HttpUtility.UrlEncode(name));
sb.Append("=");
sb.Append(HttpUtility.UrlEncode(value));
}
esc
, and then Shift + v
.(This would have highlighted the line)
d
(The line is now deleted)
p
.In a nutshell,
Esc
-> Shift + v
-> d
-> p
It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.
@Request/View/Flow/Session/ApplicationScoped
A @RequestScoped
bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped
bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null
/void
without any navigation/redirect. A @FlowScoped
bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped
bean lives as long as the established HTTP session. An @ApplicationScoped
bean lives as long as the web application runs. Note that the CDI @Model
is basically a stereotype for @Named @RequestScoped
, so same rules apply.
Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped
for simple and non-ajax forms/presentations. Use @ViewScoped
for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped
for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped
for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped
for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.
Abusing an @ApplicationScoped
bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped
bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped
bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped
bean for request, session or application scoped data, and abusing a @SessionScoped
bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.
Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped
beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty
in case of JSF managed beans or @Inject
in case of CDI managed beans.
@CustomScoped/NoneScoped/Dependent
It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped
and @NoneScoped
, which are rarely used in real world. The @CustomScoped
must refer a custom Map<K, Bean>
implementation in some broader scope which has overridden Map#put()
and/or Map#get()
in order to have more fine grained control over bean creation and/or destroy.
The JSF @NoneScoped
and CDI @Dependent
basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped
or @Dependent
is injected in a @SessionScoped
, then it will live as long as the @SessionScoped
bean.
As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.
This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped
. The flash scope is only available as a map via ExternalContext#getFlash()
in managed beans and #{flash}
in EL.
I was getting the error while trying to connect for updates. Just did as in the above answer -
Window-> Preferences-> General-> Network
There the default provider was set as Native. I changed it to direct as my laptop didn't need to connect to any proxy.
Applied and it is working fine.
I wrote a class to normalize the data in my dictionary. The 'element' in the NormalizeData class below, needs to be of dict type. And you need to replace in the __iterate() with either your custom class object or any other object type that you would like to normalize.
class NormalizeData:
def __init__(self, element):
self.element = element
def execute(self):
if isinstance(self.element, dict):
self.__iterate()
else:
return
def __iterate(self):
for key in self.element:
if isinstance(self.element[key], <ClassName>):
self.element[key] = str(self.element[key])
node = NormalizeData(self.element[key])
node.execute()
$('.DataTables_sort_wrapper').trigger("click");

You could use the following query:
SELECT table1.id
FROM table1
LEFT JOIN table2
ON table1.id IN (table2.user_one, table2.user_two)
WHERE table2.user_one IS NULL;
Although, depending on your indexes on table2
you may find that two joins performs better:
SELECT table1.id
FROM table1
LEFT JOIN table2 AS t1
ON table1.id = t1.user_one
LEFT JOIN table2 AS t2
ON table1.id = t2.user_two
WHERE t1.user_one IS NULL
AND t2.user_two IS NULL;
This is a very long explanation that I typed up for a coworker of mine. I think it would be helpful here as well. Be patient, though. I get to the real issue that you are having toward the end. Just as a teaser, it's an issue of having extra references to your Line2D
objects hanging around.
WARNING: One other note before we dive in. If you are using IPython to test this out, IPython keeps references of its own and not all of them are weakrefs. So, testing garbage collection in IPython does not work. It just confuses matters.
Okay, here we go. Each matplotlib
object (Figure
, Axes
, etc) provides access to its child artists via various attributes. The following example is getting quite long, but should be illuminating.
We start out by creating a Figure
object, then add an Axes
object to that figure. Note that ax
and fig.axes[0]
are the same object (same id()
).
>>> #Create a figure
>>> fig = plt.figure()
>>> fig.axes
[]
>>> #Add an axes object
>>> ax = fig.add_subplot(1,1,1)
>>> #The object in ax is the same as the object in fig.axes[0], which is
>>> # a list of axes objects attached to fig
>>> print ax
Axes(0.125,0.1;0.775x0.8)
>>> print fig.axes[0]
Axes(0.125,0.1;0.775x0.8) #Same as "print ax"
>>> id(ax), id(fig.axes[0])
(212603664, 212603664) #Same ids => same objects
This also extends to lines in an axes object:
>>> #Add a line to ax
>>> lines = ax.plot(np.arange(1000))
>>> #Lines and ax.lines contain the same line2D instances
>>> print lines
[<matplotlib.lines.Line2D object at 0xce84bd0>]
>>> print ax.lines
[<matplotlib.lines.Line2D object at 0xce84bd0>]
>>> print lines[0]
Line2D(_line0)
>>> print ax.lines[0]
Line2D(_line0)
>>> #Same ID => same object
>>> id(lines[0]), id(ax.lines[0])
(216550352, 216550352)
If you were to call plt.show()
using what was done above, you would see a figure containing a set of axes and a single line:
Now, while we have seen that the contents of lines
and ax.lines
is the same, it is very important to note that the object referenced by the lines
variable is not the same as the object reverenced by ax.lines
as can be seen by the following:
>>> id(lines), id(ax.lines)
(212754584, 211335288)
As a consequence, removing an element from lines
does nothing to the current plot, but removing an element from ax.lines
removes that line from the current plot. So:
>>> #THIS DOES NOTHING:
>>> lines.pop(0)
>>> #THIS REMOVES THE FIRST LINE:
>>> ax.lines.pop(0)
So, if you were to run the second line of code, you would remove the Line2D
object contained in ax.lines[0]
from the current plot and it would be gone. Note that this can also be done via ax.lines.remove()
meaning that you can save a Line2D
instance in a variable, then pass it to ax.lines.remove()
to delete that line, like so:
>>> #Create a new line
>>> lines.append(ax.plot(np.arange(1000)/2.0))
>>> ax.lines
[<matplotlib.lines.Line2D object at 0xce84bd0>, <matplotlib.lines.Line2D object at 0xce84dx3>]
>>> #Remove that new line
>>> ax.lines.remove(lines[0])
>>> ax.lines
[<matplotlib.lines.Line2D object at 0xce84dx3>]
All of the above works for fig.axes
just as well as it works for ax.lines
Now, the real problem here. If we store the reference contained in ax.lines[0]
into a weakref.ref
object, then attempt to delete it, we will notice that it doesn't get garbage collected:
>>> #Create weak reference to Line2D object
>>> from weakref import ref
>>> wr = ref(ax.lines[0])
>>> print wr
<weakref at 0xb758af8; to 'Line2D' at 0xb757fd0>
>>> print wr()
<matplotlib.lines.Line2D at 0xb757fd0>
>>> #Delete the line from the axes
>>> ax.lines.remove(wr())
>>> ax.lines
[]
>>> #Test weakref again
>>> print wr
<weakref at 0xb758af8; to 'Line2D' at 0xb757fd0>
>>> print wr()
<matplotlib.lines.Line2D at 0xb757fd0>
The reference is still live! Why? This is because there is still another reference to the Line2D
object that the reference in wr
points to. Remember how lines
didn't have the same ID as ax.lines
but contained the same elements? Well, that's the problem.
>>> #Print out lines
>>> print lines
[<matplotlib.lines.Line2D object at 0xce84bd0>, <matplotlib.lines.Line2D object at 0xce84dx3>]
To fix this problem, we simply need to delete `lines`, empty it, or let it go out of scope.
>>> #Reinitialize lines to empty list
>>> lines = []
>>> print lines
[]
>>> print wr
<weakref at 0xb758af8; dead>
So, the moral of the story is, clean up after yourself. If you expect something to be garbage collected but it isn't, you are likely leaving a reference hanging out somewhere.

An easier way to get going (assuming you already have homebrew installed, which you should, if not, go do that first and let homebrew make your life better) is to just run the following command:
brew install chromedriver
That should put the chromedriver in your path and you should be all set.
This is valid YAML:
jobs:
- name: A
schedule: "0 0/5 * 1/1 * ? *"
type: mongodb.cluster
config:
host: mongodb://localhost:27017/admin?replicaSet=rs
minSecondaries: 2
minOplogHours: 100
maxSecondaryDelay: 120
- name: B
schedule: "0 0/5 * 1/1 * ? *"
type: mongodb.cluster
config:
host: mongodb://localhost:27017/admin?replicaSet=rs
minSecondaries: 2
minOplogHours: 100
maxSecondaryDelay: 120
Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.
String array=new String[];
and String array=new String[]{};
both are invalid statement in java.
It will gives you an error that you are trying to assign String array
to String
datatype.
More specifically error is like this Type mismatch: cannot convert from String[] to String
RabbitMQ is a solid, general-purpose message broker that supports several protocols such as AMQP, MQTT, STOMP, etc. It can handle high throughput. A common use case for RabbitMQ is to handle background jobs or long-running task, such as file scanning, image scaling or PDF conversion. RabbitMQ is also used between microservices, where it serves as a means of communicating between applications, avoiding bottlenecks passing messages.
Kafka is a message bus optimized for high-throughput ingestion data streams and replay. Use Kafka when you have the need to move a large amount of data, process data in real-time or analyze data over a time period. In other words, where data need to be collected, stored, and handled. An example is when you want to track user activity on a webshop and generate suggested items to buy. Another example is data analysis for tracking, ingestion, logging or security.
Kafka can be seen as a durable message broker where applications can process and re-process streamed data on disk. Kafka has a very simple routing approach. RabbitMQ has better options if you need to route your messages in complex ways to your consumers. Use Kafka if you need to support batch consumers that could be offline or consumers that want messages at low latency.
In order to understand how to read data from Kafka, we first need to understand its consumers and consumer groups. Partitions allow you to parallelize a topic by splitting the data across multiple nodes. Each record in a partition is assigned and identified by its unique offset. This offset points to the record in a partition. In the latest version of Kafka, Kafka maintains a numerical offset for each record in a partition. A consumer in Kafka can either automatically commit offsets periodically, or it can choose to control this committed position manually. RabbitMQ will keep all states about consumed/acknowledged/unacknowledged messages. I find Kafka more complex to understand than the case of RabbitMQ, where the message is simply removed from the queue once it's acked.
RabbitMQ's queues are fastest when they're empty, while Kafka retains large amounts of data with very little overhead - Kafka is designed for holding and distributing large volumes of messages. (If you plan to have very long queues in RabbitMQ you could have a look at lazy queues.)
Kafka is built from the ground up with horizontal scaling (scale by adding more machines) in mind, while RabbitMQ is mostly designed for vertical scaling (scale by adding more power).
RabbitMQ has a built-in user-friendly interface that lets you monitor and handle your RabbitMQ server from a web browser. Among other things, queues, connections, channels, exchanges, users and user permissions can be handled - created, deleted and listed in the browser and you can monitor message rates and send/receive messages manually. Kafka has a number of open-source tools, and also some commercial once, offering the administration and monitoring functionalities. I would say that it's easier/gets faster to get a good understanding of RabbitMQ.
In general, if you want a simple/traditional pub-sub message broker, the obvious choice is RabbitMQ, as it will most probably scale more than you will ever need it to scale. I would have chosen RabbitMQ if my requirements were simple enough to deal with system communication through channels/queues, and where retention and streaming is not a requirement.
There are two main situations where I would choose RabbitMQ; For long-running tasks, when I need to run reliable background jobs. And for communication and integration within, and between applications, i.e as middleman between microservices; where a system simply needs to notify another part of the system to start to work on a task, like ordering handling in a webshop (order placed, update order status, send order, payment, etc.).
In general, if you want a framework for storing, reading (re-reading), and analyzing streaming data, use Apache Kafka. It’s ideal for systems that are audited or those that need to store messages permanently. These can also be broken down into two main use cases for analyzing data (tracking, ingestion, logging, security etc.) or real-time processing.
More reading, use cases and some comparison data can be found here: https://www.cloudamqp.com/blog/2019-12-12-when-to-use-rabbitmq-or-apache-kafka.html
Also recommending the industry paper: "Kafka versus RabbitMQ: A comparative study of two industry reference publish/subscribe implementations": http://dl.acm.org/citation.cfm?id=3093908
I do work at a company providing both Apache Kafka and RabbitMQ as a Service.
Here is a more involved example of where extends is allowed and possibly what you want:
public class A<T1 extends Comparable<T1>>
Well, it depends on what language you are using, but in general they are 2 separate configurations, each with its own settings. By default, Debug includes debug information in the compiled files (allowing easy debugging) while Release usually has optimizations enabled.
As far as conditional compilation goes, they each define different symbols that can be checked in your program, but they are language-specific macros.
Well, maven is not supposed to be good in doing fine granular tasks, it is not a scripting language like bash or ant, it is rather declarative - you say - i need a war, or an ear, and you get it. However if you need to customize how the war or ear should look like inside, you have a problem. It is just not procedural like ant, but declarative. This have some pros in the beginning, and could have a lot of cons at the end.
I guess the initial concept was to have fine plugins, that "just work" but the reality is different if you do non-standard stuff.
If you however put enough effort in your poms and few custom plugins, you'll get a much better build environment as with ant for example (depends on you project of course, but it gets more and more true for bigger projects).

In addition to the excellent answers above, the following shows how to add text to each page of a multi-page document:
using (var reader = new PdfReader(@"C:\Input.pdf"))
{
using (var fileStream = new FileStream(@"C:\Output.pdf", FileMode.Create, FileAccess.Write))
{
var document = new Document(reader.GetPageSizeWithRotation(1));
var writer = PdfWriter.GetInstance(document, fileStream);
document.Open();
for (var i = 1; i <= reader.NumberOfPages; i++)
{
document.NewPage();
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
var importedPage = writer.GetImportedPage(reader, i);
var contentByte = writer.DirectContent;
contentByte.BeginText();
contentByte.SetFontAndSize(baseFont, 12);
var multiLineString = "Hello,\r\nWorld!".Split('\n');
foreach (var line in multiLineString)
{
contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, line, 200, 200, 0);
}
contentByte.EndText();
contentByte.AddTemplate(importedPage, 0, 0);
}
document.Close();
writer.Close();
}
}
Just FYI, I had the same error and was using the correct credentials but my LDAP url was wrong :(
I got the exact same error message and code
The data members and function members that operate on the instance of the type are called instance members. The int’s ToString method (for example) are examples of instance members. By default, members are instance members. Data members and function members that don’t operate on the instance of the type, but rather on the type itself, must be marked as static. The Test.Main and Console.WriteLine methods are static methods. The Console class is actually a static class, which means all its members are static. You never actually create instances of a Console—one console is shared across the whole application.
git ls-tree --full-tree -r HEAD
and git ls-files
return all files at once. For a large project with hundreds or thousands of files, and if you are interested in a particular file/directory, you may find more convenient to explore specific directories. You can do it by obtaining the ID/SHA-1 of the directory that you want to explore and then use git cat-file -p [ID/SHA-1 of directory]
. For example:
git cat-file -p 14032aabd85b43a058cfc7025dd4fa9dd325ea97
100644 blob b93a4953fff68df523aa7656497ee339d6026d64 glyphicons-halflings-regular.eot
100644 blob 94fb5490a2ed10b2c69a4a567a4fd2e4f706d841 glyphicons-halflings-regular.svg
100644 blob 1413fc609ab6f21774de0cb7e01360095584f65b glyphicons-halflings-regular.ttf
100644 blob 9e612858f802245ddcbf59788a0db942224bab35 glyphicons-halflings-regular.woff
100644 blob 64539b54c3751a6d9adb44c8e3a45ba5a73b77f0 glyphicons-halflings-regular.woff2
In the example above, 14032aabd85b43a058cfc7025dd4fa9dd325ea97
is the ID/SHA-1 of the directory that I wanted to explore. In this case, the result was that four files within that directory were being tracked by my Git repo. If the directory had additional files, it would mean those extra files were not being tracked. You can add files using git add <file>...
of course.
You can do this :
<table id="table_header">
<tr>
<td contenteditable="true">a</td>
<td contenteditable="true">b</td>
<td contenteditable="true">c</td>
</tr>
</table>
If your C/C++ code is portable to *nix, few things are better than Valgrind.
You can also do this in phpMyAdmin without writing SQL.
Note: You'll see that phpMyAdmin is issuing the same SQL that is mentioned in the other answers.
Problem solved after I run those commands with sudo
There is boolean data type in SQL Server. Its values can be TRUE
, FALSE
or UNKNOWN
. However, the boolean data type is only the result of a boolean expression containing some combination of comparison operators (e.g. =
, <>
, <
, >=
) or logical operators (e.g. AND
, OR
, IN
, EXISTS
). Boolean expressions are only allowed in a handful of places including the WHERE
clause, HAVING
clause, the WHEN
clause of a CASE
expression or the predicate of an IF
or WHILE
flow control statement.
For all other usages, including the data type of a column in a table, boolean is not allowed. For those other usages, the BIT
data type is preferred. It behaves like a narrowed-down INTEGER
which allows only the values 0
, 1
and NULL
, unless further restricted with a NOT NULL
column constraint or a CHECK
constraint.
To use a BIT
column in a boolean expression it needs to be compared using a comparison operator such as =
, <>
or IS NULL
. e.g.
SELECT
a.answer_body
FROM answers AS a
WHERE a.is_accepted = 0;
From a formatting perspective, a bit
value is typically displayed as 0
or 1
in client software. When a more user-friendly format is required, and it can't be handled at an application tier in front of the database, it can be converted "just-in-time" using a CASE
expression e.g.
SELECT
a.answer_body,
CASE a.is_accepted WHEN 1 THEN 'TRUE' ELSE 'FALSE' END AS is_accepted
FROM answers AS a;
Storing boolean values as a character data type like char(1)
or varchar(5)
is also possible, but that is much less clear, has more storage/network overhead, and requires CHECK
constraints on each column to restrict illegal values.
For reference, the schema of answers
table would be similar to:
CREATE TABLE answers (
...,
answer_body nvarchar(MAX) NOT NULL,
is_accepted bit NOT NULL DEFAULT (0)
);
You can use the following method inside the catch block:
response.sendError(HttpStatus.UNAUTHORIZED.value(), "Invalid token")
Notice that you can use any HttpStatus code and a custom message.
If you'd like to know how to sort a linked list without using standard Java libraries, I'd suggest looking at different algorithms yourself. Examples here show how to implement an insertion sort, another StackOverflow post shows a merge sort, and ehow even gives some examples on how to create a custom compare function in case you want to further customize your sort.
This:
var foo = new Foo();
and
var foo = Object.create(Foo.prototype);
are quite similar. One important difference is that new Foo
actually runs constructor code, whereas Object.create
will not execute code such as
function Foo() {
alert("This constructor does not run with Object.create");
}
Note that if you use the two-parameter version of Object.create()
then you can do much more powerful things.
Use this:
mainWindow = new BrowserWindow({width: 640, height: 360})
mainWindow.setMenuBarVisibility(false)

I tried mainWindow.setMenu(null)
, but it didn't work.
Just do myFunction.foo = "bar"
and it will add it. myFunction
is the name of the object in this case.
select * from all_constraints
where owner = '<NAME>'
and constraint_name = 'SYS_C00381400'
/
Like all data dictionary views, this a USER_CONSTRAINTS view if you just want to check your current schema and a DBA_CONSTRAINTS view for administration users.
The construction of the constraint name indicates a system generated constraint name. For instance, if we specify NOT NULL in a table declaration. Or indeed a primary or unique key. For example:
SQL> create table t23 (id number not null primary key)
2 /
Table created.
SQL> select constraint_name, constraint_type
2 from user_constraints
3 where table_name = 'T23'
4 /
CONSTRAINT_NAME C
------------------------------ -
SYS_C00935190 C
SYS_C00935191 P
SQL>
'C'
for check, 'P'
for primary.
Generally it's a good idea to give relational constraints an explicit name. For instance, if the database creates an index for the primary key (which it will do if that column is not already indexed) it will use the constraint name oo name the index. You don't want a database full of indexes named like SYS_C00935191
.
To be honest most people don't bother naming NOT NULL constraints.
I've found out the solution! Thanks to Firebug ;)
//"markers" is an array that I declared which contains all the marker of the map
//"i" is the index of the marker in the array that I want to trigger the OnClick event

The best and the most effective way to learn new things is to see and study real world practical examples. Suppose for a moment that you want to build a blog in django where reporters can write and publish news articles. The owner of the online newspaper wants to allow each of his reporters to publish as many articles as they want, but does not want different reporters to work on the same article. This means that when readers go and read an article they will se only one author in the article.
For example: Article by John, Article by Harry, Article by Rick. You can not have Article by Harry & Rick because the boss does not want two or more authors to work on the same article.
How can we solve this 'problem' with the help of django? The key to the solution of this problem is the django ForeignKey
.
The following is the full code which can be used to implement the idea of our boss.
from django.db import models
# Create your models here.
class Reporter(models.Model):
first_name = models.CharField(max_length=30)
def __unicode__(self):
return self.first_name
class Article(models.Model):
title = models.CharField(max_length=100)
reporter = models.ForeignKey(Reporter)
def __unicode__(self):
return self.title
Run python manage.py syncdb
to execute the sql code and build the tables for your app in your database. Then use python manage.py shell
to open a python shell.
Create the Reporter object R1.
In [49]: from thepub.models import Reporter, Article
In [50]: R1 = Reporter(first_name='Rick')
In [51]: R1.save()
Create the Article object A1.
In [5]: A1 = Article.objects.create(title='TDD In Django', reporter=R1)
In [6]: A1.save()
Then use the following piece of code to get the name of the reporter.
In [8]: A1.reporter.first_name
Out[8]: 'Rick'
Now create the Reporter object R2 by running the following python code.
In [9]: R2 = Reporter.objects.create(first_name='Harry')
In [10]: R2.save()
Now try to add R2 to the Article object A1.
In [13]: A1.reporter.add(R2)
It does not work and you will get an AttributeError saying 'Reporter' object has no attribute 'add'.
As you can see an Article object can not be related to more than one Reporter object.
What about R1? Can we attach more than one Article objects to it?
In [14]: A2 = Article.objects.create(title='Python News', reporter=R1)
In [15]: R1.article_set.all()
Out[15]: [<Article: Python News>, <Article: TDD In Django>]
This practical example shows us that django ForeignKey
is used to define many-to-one relationships.
OneToOneField
is used to create one-to-one relationships.
We can use reporter = models.OneToOneField(Reporter)
in the above models.py file but it is not going to be useful in our example as an author will not be able to post more than one article.
Each time you want to post a new article you will have to create a new Reporter object. This is time consuming, isn't it?
I highly recommend to try the example with the OneToOneField
and realize the difference. I am pretty sure that after this example you will completly know the difference between django OneToOneField
and django ForeignKey
.
Managing a connection (or a pool of connections) to a database.
I would use it also to retrieve and store informations on external configuration files.
Two references refer to same object as long as there is no reassignment.
Any updates in the same object won't make the references to new memory since it still is in same memory. Here are few examples :
a = "first string"
b = a
b.upcase!
=> FIRST STRING
a
=> FIRST STRING
b = "second string"
a
=> FIRST STRING
hash = {first_sub_hash: {first_key: "first_value"}}
first_sub_hash = hash[:first_sub_hash]
first_sub_hash[:second_key] = "second_value"
hash
=> {first_sub_hash: {first_key: "first_value", second_key: "second_value"}}
def change(first_sub_hash)
first_sub_hash[:third_key] = "third_value"
end
change(first_sub_hash)
hash
=> {first_sub_hash: {first_key: "first_value", second_key: "second_value", third_key: "third_value"}}
The following is from Adobe docs.
The media queries specification also provides the keyword only
, which is intended to hide media queries from older browsers. Like not
, the keyword must come at the beginning of the declaration. For example:
media="only screen and (min-width: 401px) and (max-width: 600px)"
Browsers that don't recognize media queries expect a comma-separated list of media types, and the specification says they should truncate each value immediately before the first nonalphanumeric character that isn't a hyphen. So, an old browser should interpret the preceding example as this:
media="only"
Because there is no such media type as only, the stylesheet is ignored. Similarly, an old browser should interpret
media="screen and (min-width: 401px) and (max-width: 600px)"
as
media="screen"
In other words, it should apply the style rules to all screen devices, even though it doesn't know what the media queries mean.
Unfortunately, IE 6–8 failed to implement the specification correctly.
Instead of applying the styles to all screen devices, it ignores the style sheet altogether.
In spite of this behavior, it's still recommended to prefix media queries with only if you want to hide the styles from other, less common browsers.
So, using
media="only screen and (min-width: 401px)"
and
media="screen and (min-width: 401px)"
will have the same effect in IE6-8: both will prevent those styles from being used. They will, however, still be downloaded.
Also, in browsers that support CSS3 media queries, both versions will load the styles if the viewport width is larger than 401px
and the media type is screen.
I'm not entirely sure which browsers that don't support CSS3 media queries would need the only
version
media="only screen and (min-width: 401px)"
as opposed to
media="screen and (min-width: 401px)"
to make sure it is not interpreted as
media="screen"
It would be a good test for someone with access to a device lab.
Try below code. it will extract all image from pdf.

for obj in xObject:
if xObject[obj]['/Subtype'] == '/Image':
size = (xObject[obj]['/Width'], xObject[obj]['/Height'])
print(size)

print(xObject[obj]['/Filter'])
if xObject[obj]['/Filter'][0] == '/DCTDecode':
img_name=str(x)+".jpg"
print(img_name)
img = open(img_name, "wb")
img.write(data)
img.close()
print(str(x)+" is done")
Do you want the files to save as UTF-8 because you are using special characters that would be lost in ASCII encoding? If that's the case, then there is a VS2008 global setting in Tools > Options > Environment > Documents
, named Save documents as Unicode when data cannot be saved in codepage
. When this is enabled, VS2008 will save as Unicode if certain characters cannot be represented in the otherwise-default codepage.
Also, which files are not being saved as UTF-8? All of my .cs, .csproj, .sln, .config, .as*x, etc, all save as UTF-8 (with signature, the byte order marks), by default.

The pertinent section reads:
There's no setting to fetch all records. You wouldn't like SQL Developer to fetch for minutes on big tables anyway. If, for 1 specific table, you want to fetch all records, you can do Control-End in the results pane to go to the last record. You could time the fetching time yourself, but that will vary on the network speed and congestion, the program (SQL*Plus will be quicker than SQL Dev because it's more simple), etc.
There is also a button on the toolbar which is a "Fetch All
" button.
FWIW Be careful retrieving all records, for a very large recordset it could cause you to have all sorts of memory issues etc.
As far as I know, SQL Developer uses JDBC behind the scenes to fetch the records and the limit is set by the JDBC setMaxRows()
procedure, if you could alter this (it would prob be unsupported) then you might be able to change the SQL Developer behaviour.
here's a way using the SSSE3 instruction pshufb using its Intel intrinsic, assuming you have a multiple of 4 int
s:
unsigned int *bswap(unsigned int *destination, unsigned int *source, int length) {
int i;
__m128i mask = _mm_set_epi8(12, 13, 14, 15, 8, 9, 10, 11, 4, 5, 6, 7, 0, 1, 2, 3);
for (i = 0; i < length; i += 4) {
_mm_storeu_si128((__m128i *)&destination[i],
_mm_shuffle_epi8(_mm_loadu_si128((__m128i *)&source[i]), mask));
}
return destination;

If you have a mixture of formats in your date, don't forget to set infer_datetime_format=True
to make life easier.
df['date'] = pd.to_datetime(df['date'], infer_datetime_format=True)
Source: pd.to_datetime
or if you want a customized approach:
def autoconvert_datetime(value):
formats = ['%m/%d/%Y', '%m-%d-%y'] # formats to try
result_format = '%d-%m-%Y' # output format
for dt_format in formats:
try:
dt_obj = datetime.strptime(value, dt_format)
return dt_obj.strftime(result_format)
except Exception as e: # throws exception when format doesn't match
pass
return value # let it be if it doesn't match
df['date'] = df['date'].apply(autoconvert_datetime)
You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.
ECMAScript 6 introduced arrow functions so now the setTimeout() or setInterval() don't have to look like this:
setTimeout(function() { FetchData(); }, 1000)
Instead, you can use annonymous arrow function which looks cleaner, and less confusing:
setTimeout(() => {FetchData();}, 1000)
You can concatenate strings by using the sprintf() function. In your case, for example:
char file[80];
sprintf(file,"%s%s",name,extension);
And you'll end having the concatenated string in "file".
In ASP.NET Core 2.2, a new Server/ hosting pattern was released with IIS called IIS InProcess hosting. To enable inprocess hosting, the csproj element AspNetCoreHostingModel is added to set the hostingModel to inprocess in the web.config file. Also, the web.config points to a new module called AspNetCoreModuleV2 which is required for inprocess hosting.
If the target machine you are deploying to doesn't have ANCMV2, you can't use IIS InProcess hosting. If so, the right behavior is to either install the dotnet hosting bundle to the target machine or downgrade to the AspNetCoreModule.
Try changing the section in csproj (edit with a text editor)
<PropertyGroup>
<TargetFramework>netcoreapp2.2</TargetFramework>
<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
</PropertyGroup>
to the following ...
<PropertyGroup>
<TargetFramework>netcoreapp2.2</TargetFramework>
<AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
<AspNetCoreModuleName>AspNetCoreModule</AspNetCoreModuleName>

Follow up to accepted answer.
You need something other than CTRL-D to designate the end if using this in a script. Try this instead:
cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF
This will append text to the stated file (not including "EOF").
It utilizes a here document (or heredoc).
However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.
This variation will work when you are typing directly on the command line:
sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'
Or you can use tee
instead to avoid the command line sudo issue seen when using the heredoc with cat:
tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF
I frankly would recommend the RazorGenerator nuget package. That way your views have a .designer.cs
file generated when you save them and on top of getting compile time errors for you views, they are also precompiled into the assembly (= faster warmup) and Resharper provides some additional help as well.
To use this include the RazorGenerator nuget package in you ASP.NET MVC project and install the "Razor Generator" extension under item under Tools ? Extensions and Updates.
We use this and the overhead per compile with this approach is much less. On top of this I would probably recommend .NET Demon by RedGate which further reduces compile time impact substantially.
Hope this helps.
Check this:
// Define the border style of the form to a dialog box.
form1.FormBorderStyle = FormBorderStyle.FixedDialog;
// Set the MaximizeBox to false to remove the maximize box.
form1.MaximizeBox = false;
// Set the MinimizeBox to false to remove the minimize box.
form1.MinimizeBox = false;
// Set the start position of the form to the center of the screen.
form1.StartPosition = FormStartPosition.CenterScreen;
// Display the form as a modal dialog box.
form1.ShowDialog();
FileReaderJS can read the files for you. You get the file content inside onLoad(e)

self.interactivePopGestureRecognizer.enabled = NO;
}
And enable in viewDidDisappear:
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
Also, add UINavigationControllerDelegate

I replace Jasmine's toThrow matcher with the following, which lets you match on the exception's name property or its message property. For me this makes tests easier to write and less brittle, as I can do the following:
throw {
name: "NoActionProvided",
message: "Please specify an 'action' property when configuring the action map."
}
and then test with the following:
expect (function () {
.. do something
}).toThrow ("NoActionProvided");
This lets me tweak the exception message later without breaking tests, when the important thing is that it threw the expected type of exception.
This is the replacement for toThrow that allows this:
jasmine.Matchers.prototype.toThrow = function(expected) {
var result = false;
var exception;
if (typeof this.actual != 'function') {
throw new Error('Actual is not a function');
}
try {
this.actual();
} catch (e) {
exception = e;
}
if (exception) {
result = (expected === jasmine.undefined || this.env.equals_(exception.message || exception, expected.message || expected) || this.env.equals_(exception.name, expected));
}
var not = this.isNot ? "not " : "";
this.message = function() {
if (exception && (expected === jasmine.undefined || !this.env.equals_(exception.message || exception, expected.message || expected))) {
return ["Expected function " + not + "to throw", expected ? expected.name || expected.message || expected : " an exception", ", but it threw", exception.name || exception.message || exception].join(' ');
} else {
return "Expected function to throw an exception.";
}
};
return result;
};

You can do that, or you can use the readfile
function, which outputs it for you:
header('Content-Type: image/x-png'); //or whatever
readfile('thefile.png');
die();
Edit: Derp, fixed obvious glaring typo.
No you don't have to put credentials, You have to put headers on client side eg:
$http({
url: 'url of service',
method: "POST",
data: {test : name },
withCredentials: true,
headers: {
'Content-Type': 'application/json; charset=utf-8'
}
});
And and on server side you have to put headers to this is example for nodejs:
/**
* On all requests add headers
*/
app.all('*', function(req, res,next) {
/**
* Response settings
* @type {Object}
*/
var responseSettings = {
"AccessControlAllowOrigin": req.headers.origin,
"AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Date, X-Api-Version, X-File-Name",
"AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
"AccessControlAllowCredentials": true
};
/**
* Headers
*/
res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
res.header("Access-Control-Allow-Origin", responseSettings.AccessControlAllowOrigin);
res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);
if ('OPTIONS' == req.method) {
res.send(200);
}
else {
next();
}
});
First do a loop using a filter that will return only unique teams, and then a nested loop that returns all players per current team:

<div ng-repeat="playerPerTeam in playersToFilter() | filter:filterTeams">
<b>{{playerPerTeam.team}}</b>
<li ng-repeat="player in players | filter:{team: playerPerTeam.team}">{{player.name}}</li>
</div>
</div>
script:
function Main($scope) {
$scope.players = [{name: 'Gene', team: 'team alpha'},
{name: 'George', team: 'team beta'},
{name: 'Steve', team: 'team gamma'},
{name: 'Paula', team: 'team beta'},
{name: 'Scruath of the 5th sector', team: 'team gamma'}];
var indexedTeams = [];
// this will reset the list of indexed teams each time the list is rendered again
$scope.playersToFilter = function() {
indexedTeams = [];
return $scope.players;
}
$scope.filterTeams = function(player) {
var teamIsNew = indexedTeams.indexOf(player.team) == -1;
if (teamIsNew) {
indexedTeams.push(player.team);
}
return teamIsNew;
}
}

To remove newlines, use tr:
tr -d '\n'
If you want to replace each newline with a single space:

The error ba: Event not found
is coming from csh, and is due to csh trying to match !ba
in your history list. You can escape the !
and write the command:
sed ':a;N;$\!ba;s/\n/ /g' # Suitable for csh only!!
but sed is the wrong tool for this, and you would be better off using a shell that handles quoted strings more reasonably. That is, stop using csh and start using bash.
You could use the json
module for this. The dumps
function in this module converts a JSON object into a properly formatted string which you can then print.
import json
cars = {'A':{'speed':70, 'color':2},
'B':{'speed':60, 'color':3}}
print(json.dumps(cars, indent = 4))
The output looks like
{ "A": { "color": 2, "speed": 70 }, "B": { "color": 3, "speed": 60 } }
The documentation also specifies a bunch of useful options for this method.
Much simpler: use sudo
to run a shell and use a heredoc to feed it commands.
#!/usr/bin/env bash
whoami
sudo -i -u someuser bash << EOF
echo "In"
whoami
EOF
echo "Out"
whoami

I'm wondering whether you meant "recursive". Here is a simple example of a recursive function to compute the factorial function:
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n - 1)
The two key elements of a recursive algorithm are:
n == 0
factorial(n - 1)
You have to retrieve it from the HOST
header.
var host = req.get('host');
It is optional with HTTP 1.0, but required by 1.1. And, the app can always impose a requirement of its own.
If this is for supporting cross-origin requests, you would instead use the Origin
header.
var origin = req.get('origin');
Note that some cross-origin requests require validation through a "preflight" request:
req.options('/route', function (req, res) {
var origin = req.get('origin');
// ...
});
If you're looking for the client's IP, you can retrieve that with:
var userIP = req.socket.remoteAddress;
Note that, if your server is behind a proxy, this will likely give you the proxy's IP. Whether you can get the user's IP depends on what info the proxy passes along. But, it'll typically be in the headers as well.

To keep the accordion nature intact when wanting to also use 'hide' and 'show' functions like .collapse( 'hide' )
, you must initialize the collapsible panels with the parent property set in the object with toggle: false
before making any calls to 'hide' or 'show'
// initialize collapsible panels
$('#accordion .collapse').collapse({
toggle: false,
parent: '#accordion'
});
// show panel one (will collapse others in accordion)
$( '#collapseOne' ).collapse( 'show' );
// show panel two (will collapse others in accordion)
$( '#collapseTwo' ).collapse( 'show' );
// hide panel two (will not collapse/expand others in accordion)
$( '#collapseTwo' ).collapse( 'hide' );

I would suggest to use qs npm package
qs.stringify({a:"1=2", b:"Test 1"}); // gets a=1%3D2&b=Test+1
it is easier to use with JS object and it gives you proper URL encoding for all parameters
If you are using jQuery I would go for $.param
method. It URL encodes an object mapping fields to values, which is easier to read than calling an escape method on each value.
$.param({a:"1=2", b:"Test 1"}) // gets a=1%3D2&b=Test+1
HTML file:
<head>
<meta charset="utf-8">
</head>
PHP file :
<?php header('Content-type: text/plain; charset=utf-8'); ?>
You can use the values 'TRUE'
and 'FALSE'
.
From https://docs.microsoft.com/en-us/sql/t-sql/data-types/bit-transact-sql:
The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.
You can detect which button (ok or cancel) pressed by user, because the onunload function called only when the user choise leaveing the page. Althoug in this funcion the possibilities is limited, because the DOM is being collapsed. You can run javascript, but the ajax POST doesn't do anything therefore you can't use this methode for automatic logout. But there is a solution for that. The window.open('logout.php') executed in the onunload funcion, so the user will logged out with a new window opening.
function onunload = (){
window.open('logout.php');
}
This code called when user leave the page or close the active window and user logged out by 'logout.php'. The new window close immediately when logout php consist of code:
window.close();
Is the
???
free to be defined by the user?
Yes.
or is it supplied by the HTML?
No. HTML has nothing to do with that. Read below.
Is it possible for me to define the
???
asabcdefg
?
Yes.
If you want to send the following data to the web server:
name = John
age = 12
using application/x-www-form-urlencoded
would be like this:
name=John&age=12
As you can see, the server knows that parameters are separated by an ampersand &
. If &
is required for a parameter value then it must be encoded.
So how does the server know where a parameter value starts and ends when it receives an HTTP request using multipart/form-data
?
Using the boundary, similar to &
.
For example:
--XXX
Content-Disposition: form-data; name="name"
John
--XXX
Content-Disposition: form-data; name="age"
12
--XXX--
In that case, the boundary value is XXX
. You specify it in the Content-Type
header so that the server knows how to split the data it receives.
So you need to:
Use a value that won't appear in the HTTP data sent to the server.
Be consistent and use the same value everywhere in the request message.
mongo db_name --eval "db.user_info.find().forEach(function(o) {print(o._id);})"
It may have side effects if there are other listeners, and it doesn't feel as nice as interacting through the plugins API -- but it gives a less verbose code if you just "click" the tab, rather than count it's index and set it active afterwards, and it's pretty intuitive what's going on. Also it wont fail if the ui-guys decide to rename the option again.
$('#tabs').tabs();
$('#tabs a[href="#tabtwo"]').click();
It's intriguing, though, that the ui tabs code has a meta-function (_getIndex
) with the comment:
"meta-function to give users option to provide a href string instead of a numerical index"
but does not use it when setting the active option, only when calling enable, disable and load.
You should really be using checkboxes if there will be an instance where something isn't selected.
according to the W3C
If no radio button in a set sharing the same control name is initially "on", user agent behavior for choosing which control is initially "on" is undefined. Note. Since existing implementations handle this case differently, the current specification differs from RFC 1866 ([RFC1866] section 8.1.2.4), which states:
At all times, exactly one of the radio buttons in a set is checked. If none of the elements of a set of radio buttons specifies `CHECKED', then the user agent must check the first radio button of the set initially.
Since user agent behavior differs, authors should ensure that in each set of radio buttons that one is initially "on".
Your outer loop is looping over all the words in the list. It's unnecessary and will cause you problems. Remove it and it should work properly.
Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.
Copied from IIS Modules Overview: Preconditions
My guess is that the folder you are trying to add already exists in SVN. You can confirm by checking out the files to a different folder and see if trunk already has the required folder.
It sounds like your database dump includes the information for creating the database. So don't give the MySQL command line a database name. It will create the new database and switch to it to do the import.
Simple:

Cheers!
Modern processors are too fast to register the running time. Hence it may return zero. In this case, the time you started and ended is too small and therefore both the times are the same after round of.
You could create a db wrapper then require it. node's require returns the same instance of a module every time, so you can perform your connection and return a handler. From the Node.js docs:
every call to require('foo') will get exactly the same object returned, if it would resolve to the same file.
You could create db.js
:
var mysql = require('mysql');
var connection = mysql.createConnection({
host : '127.0.0.1',
user : 'root',
password : '',
database : 'chat'
});
connection.connect(function(err) {
if (err) throw err;
});
module.exports = connection;
Then in your app.js
, you would simply require it.
var express = require('express');
var app = express();
var db = require('./db');
app.get('/save',function(req,res){
var post = {from:'me', to:'you', msg:'hi'};
db.query('INSERT INTO messages SET ?', post, function(err, result) {
if (err) throw err;
});
});
server.listen(3000);
This approach allows you to abstract any connection details, wrap anything else you want to expose and require db
throughout your application while maintaining one connection to your db thanks to how node require works :)
My first suggestion is to use Designer to create your GUIs. Typing them out yourself sucks, takes more time, and you will definitely make more mistakes than Designer.
Here are some PyQt tutorials to help get you on the right track. The first one in the list is where you should start.
A good guide for figuring out what methods are available for specific classes is the PyQt4 Class Reference. In this case you would look up QLineEdit
and see the there is a text
method.
To answer your specific question:
To make your GUI elements available to the rest of the object, preface them with self.
import sys
from PyQt4.QtCore import SIGNAL
from PyQt4.QtGui import QDialog, QApplication, QPushButton, QLineEdit, QFormLayout
class Form(QDialog):
def __init__(self, parent=None):
super(Form, self).__init__(parent)
self.le = QLineEdit()
self.le.setObjectName("host")
self.le.setText("Host")
self.pb = QPushButton()
self.pb.setObjectName("connect")
self.pb.setText("Connect")
layout = QFormLayout()
layout.addWidget(self.le)
layout.addWidget(self.pb)
self.setLayout(layout)
self.connect(self.pb, SIGNAL("clicked()"),self.button_click)
self.setWindowTitle("Learning")
def button_click(self):
# shost is a QString object
shost = self.le.text()
print shost
app = QApplication(sys.argv)
form = Form()
form.show()
app.exec_()
If you already know the filename
, you can use the boto3
builtin download_fileobj
import boto3
from io import BytesIO
session = boto3.Session()
s3_client = session.client("s3")
f = BytesIO()
s3_client.download_fileobj(bucket_name, filename, f)
f.seek(0)
print(f.getvalue())
Since they are already inline-block
child elements, you can set text-align:center
on the parent without having to set a width
or margin:0px auto
on the child. Meaning it will work for dynamically generated content with varying widths
.
.img_container, .img_container2 {
text-align: center;
}
This will center the child within both div
containers.
UPDATE:
For vertical centering, you can use the calc()
function assuming the height of the icon is known.
.img_container > i, .img_container2 > i {
position:relative;
top: calc(50% - 10px); /* 50% - 3/4 of icon height */
}
jsFiddle demo - it works.
For what it's worth - you can also use vertical-align:middle
assuming display:table-cell
is set on the parent.
try :
mvn install:install-file -DgroupId=jdk.tools -DartifactId=jdk.tools -Dversion=1.6 -Dpackaging=jar -Dfile="C:\Program Files\Java\jdk\lib\tools.jar"

Use Sheets rather than Sheet and activate them sequentially:
Sub kl()
Dim wb As Workbook
Dim ws As Worksheet
Set wb = ActiveWorkbook
Set ws = Sheets("Sheet1")
wb.Activate
ws.Select
End Sub
Use the function advance(startIndex, endIndex)
:
var str = "45+22"
str = str.substringToIndex(advance(str.startIndex, countElements(str) - 1))
var birthDate = ... // DOB
var resultDate = DateTime.Now - birthDate;
Using resultDate
you can apply TimeSpan
properties whatever you want to display it.
In my case both 2015 express web and 2015 Community had memory leaks (up to 1.5 GB) froze and crashed every 5 minutes. But only in projects with Node js. what solved this issue for me was disabling the intellisense: tools--> options--> text editor-->Node.js--> intellisense-->intellisense level=No intellisense.
And somehow intellisense still works))
Another way to do it:
switch date1.compare(date2) {
case .orderedAscending:
break
case .orderedDescending:
break;
case .orderedSame:
break
}
change Date to Object which is between parenthesis
Depending on how you want the result, you can also print each number in a for loop:
def numbers():
for i in range(int(input('How far do you wanna go? '))+1):
print(i)
So if the user input was 7 for example:
How far do you wanna go? 7
0
1
2
3
4
5
6
7
You can also delete the '+1' in the for loop and place it on the print statement, which will change it to starting at 1 instead of 0.
I am getting this issue when using owl carousal and scrolling the images.
So get solved just adding below CSS in your page.
.owl-carousel {
-ms-touch-action: pan-y;
touch-action: pan-y;
}
or
.owl-carousel {
-ms-touch-action: none;
touch-action: none;
}
Surprised nobody brought this one up:
# To remove last n rows
df.head(-n)
# To remove first n rows
df.tail(-n)
Running a speed test on a DataFrame of 1000 rows shows that slicing and head
/tail
are ~6 times faster than using drop
:
>>> %timeit df[:-1]
125 µs ± 132 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
>>> %timeit df.head(-1)
129 µs ± 1.18 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
>>> %timeit df.drop(df.tail(1).index)
751 µs ± 20.4 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
This would be easier to do with flexbox. Using flexbox will let you not to specify the height of your content and can adjust automatically on the height it contains.
here's the gist of the demo
.container{
display: flex;
height: 100%;
justify-content: center;
align-items: center;
}
html
<div class="container">
<div class='content'> //you can size this anyway you want
put anything you want here,
</div>
</div>
If you want to use the variable as enum, just add the function:
Enum EVehicle {
Car = 'car',
Bike = 'bike',
Truck = 'truck'
}
const getVehicleAsEnum = (vehicleStr:string) => vehicleStr === 'car' ? EVehicle.Car : vehicleStr === 'bike' ? EVehicle.Bike : vehicleStr === 'truck' ? EVehicle.Truck : undefined
And then test:
const vehicleEnum = getVecicleAsEnum(str)
if(vehicleEnum) {
// do something
}
Class selectors are prefixed with a dot. Your .find()
is missing that so jQuery thinks you're looking for <myClass>
elements.
var myVar = $("#start").find('.myClass').val();

alertController.setValue(titleAttrString, forKey: "attributedTitle")
alertController.setValue(messageAttrString, forKey: "attributedMessage")
// djb2 hash function

while (c = *str++)
hash = ((hash << 5) + hash) + c; /* hash * 33 + c */
return hash;
}
if you want to use "System.Data.Objects.EntityFunctions"
use "System.Data.Entity.DbFunctions" in EF 6.1+
Class is for applying your style to a group of elements. ID styles apply to just the element with that ID (there should only be one). Usually you use classes, but if there's a one-off you can use IDs (or just stick the style straight into the element).
_mytexteditingcontroller.value = new TextEditingController.fromValue(new TextEditingValue(text: "My String")).value;
This seems to work if anyone has a better way please feel free to let me know.
Shortest Yet !!!
=f.hidden_field :title, :value => "some value"
Shorter, DRYer and perhaps more obvious.
Of course with ruby 1.9 and the new hash format we can go 3 characters shorter with...
=f.hidden_field :title, value: "some value"
Demo :
<connectionStrings>
<add name="myConnectionString" connectionString="server=localhost;database=myDb;uid=myUser;password=myPass;" />
</connectionStrings>
Based on your question:
<connectionStrings>
<add name="itmall" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True" />
</connectionStrings>
Refer links:
http://www.connectionstrings.com/store-connection-string-in-webconfig/
Retrive connection string from web.config file:
write the below code in your file where you want;
string connstring=ConfigurationManager.ConnectionStrings["itmall"].ConnectionString;
SqlConnection con = new SqlConnection(connstring);
or you can go in your way like
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["itmall"].ConnectionString);
Note:
The "name" which you gave in web.config file and name which you used in connection string must be same(like "itmall" in this solution.)
I had the same problem. I populated the field with /home/tim/android.jks file from tutorial thinking that file would be created. and when i would click enter it would say cant find the file. but when i would try to create the file, it would not let me create the jks file. I closed out of android studio and ran it again and it worked fine. I had to hit the ... to correctly add my file. generate signed apk wizard-->new key store-->hit ... choose key store file. enter filename I was thinking i was going to have to use openjdk and create my own keyfile, but it is built into android studio
int power(int n, int b) {
int number;
number = pow(n, b);
return number;
}
void NumberOfDigits() {
int n, a;
printf("Eneter number \n");
scanf_s("%d", &n);
int i = 0;
do{
i++;
} while (n / pow(10, i) > 1);
printf("Number of digits is: \t %d \n", i);
for (int j = i-1; j >= 0; j--) {
a = n / power(10, j) % 10;
printf("%d \n", a);
}
}
int main(void) {
NumberOfDigits();
}
If you're not worried about a couple minutes time to do so, a solution would be to rm -rf node_modules
and npm install
again to rebuild the local modules.
Technically redirect should be used either if we need to transfer control to different domain or to achieve separation of task.
For example in the payment application we do the PaymentProcess first and then redirect to displayPaymentInfo. If the client refreshes the browser only the displayPaymentInfo will be done again and PaymentProcess will not be repeated. But if we use forward in this scenario, both PaymentProcess and displayPaymentInfo will be re-executed sequentially, which may result in incosistent data.
For other scenarios, forward is efficient to use since as it is faster than sendRedirect
You need to delete your old db folder and recreate new one. It will resolve your issue.
I am using this code, which I find more practical than the accepted answer above:
List<Thing> thingList = new ArrayList<>(thingSet);
thingList.sort((thing1, thing2) -> thing1.getName().compareToIgnoreCase(thing2.getName()));
I used following:
if str and not str.isspace():
print('not null and not empty nor whitespace')
else:
print('null or empty or whitespace')

You have to use ==
to compare (or even ===
, if you want to compare types). A single =
is for assignment.
if (one == 'rock' && two == 'rock') {
console.log('Tie! Try again!');
}
Use the placeholder attribute. The text disappears when the user starts typing. This is an example of a project I am working on:
<div class="" id="search-form">
<input type="text" name="" value="" class="form-control" placeholder="Search..." >
</div>
Update for PHP 7 (thanks shock_gone_wild)
PHP 7 introduces the so called null coalescing operator which simplifies the below statements to:
$var = $var ?? "default";
Before PHP 7
No, there is no special operator or special syntax for this. However, you could use the ternary operator:
$var = isset($var) ? $var : "default";
Or like this:
isset($var) ?: $var = 'default';
import numpy as np
n = 51 #number of data points
# Suppose the real and imaginary parts are created independently
real_part = np.random.normal(size=n)
imag_part = np.random.normal(size=n)
# Create a complex array - the imaginary part will be equal to zero
z = np.array(real_part, dtype=complex)
# Now define the imaginary part:
z.imag = imag_part
print(z)
h2.text-left{
position:relative;
top:50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
}
Explanation:
The top:50% style essentially pushes the header element down 50% from the top of the parent element. The translateY stylings also act in a similar manner by moving then element down 50% from the top.
Please note that this works well for headers with 1 (maybe 2) lines of text as this simply moves the top of the header element down 50% and then the rest of the content fills in below that, which means that with multiple lines of text it would appear to be slightly below vertically aligned.
A possible fix for multiple lines would be to use a percentage slightly less than 50%.
If you using angular-cli Keep the json file inside Assets folder (parallel to app dir) directory
return this.http.get('<json file path inside assets folder>.json'))
.map((response: Response) => {
console.log("mock data" + response.json());
return response.json();
}
)
.catch(this.handleError);
}
Note: here you only need to give path inside assets folder like assets/json/oldjson.json then you need to write path like /json/oldjson.json
If you using webpack then you need to follow above same structure inside public folder its similar like assets folder.
I know this question is old, but for the one's what are new, here is what you can do:
HTML
<img id="demo" src="myImage.png">
<button onclick="myFunction()">Click Me!</button>
JAVASCRIPT
function myFunction() {
document.getElementById('demo').src = "myImage.png";
}
Yes, it is. Declare parameter as so:
@Sort varchar(50) = NULL
Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).
Just put all of the symbols in this order (I only tested it in this order since it makes the most sense code-wise to me).
Notice for the body link... I just put... ;?&body=
. Also, notice that I have found I needed to use %20
for any spaces.
I have tested it on my iphone (v. 9.2) and another android and it works just fine.
This will solve the issue with having to hack it for different devices. I have no artifacts when I tested it in the SMS.

I use the below mentioned process to convert equations to markdown. This works very well for me. Its very simple!!
Let's say, I want to represent matrix multiplication equation
Get the script for your formulae from here - https://csrgxtu.github.io/2015/03/20/Writing-Mathematic-Fomulars-in-Markdown/
My example: I wanted to represent Z(i,j)=X(i,k) * Y(k, j); k=1 to n
into a summation formulae.
Referencing the website, the script needed was => Z_i_j=\sum_{k=1}^{10} X_i_k * Y_k_j
Use URL encoder - https://www.urlencoder.org/ to convert the script to a valid url
My example:
Use this website to generate the image by copy-pasting the output from Step 2 in the "eq" request parameter - http://www.sciweavers.org/tex2img.php?eq=<b><i>paste-output-here</i></b>&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=
- My example:
http://www.sciweavers.org/tex2img.php?eq=Z_i_j=\sum_{k=1}^{10}%20X_i_k%20*%20Y_k_j&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=
Reference image using markdown syntax - ![alt text](enter url here)
- Copy this in your markdown and you are good to go:
![Z(i,j)=X(i,k) * Y(k, j); k=1 to n](http://www.sciweavers.org/tex2img.php?eq=Z_i_j%3D%5Csum_%7Bi%3D1%7D%5E%7B10%7D%20X_i_k%20%2A%20Y_k_j&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=)
Do you execute the script from the command line on Linux or UNIX? In that case, you could just use
time ./script.py
If you are trying to get an index based on a predicate, try this:
If you only care about the first index:
OptionalInt index = IntStream.range(0, list.size())
.filter(i -> list.get(i) == 3)
.findFirst();
Or if you want to find multiple indexes:
IntStream.range(0, list.size())
.filter(i -> list.get(i) == 3)
.collect(Collectors.toList());
Add .orElse(-1);
in case you want to return a value if it doesn't find it.
No. gettimeofday should NEVER be used to measure time.
This is causing bugs all over the place. Please don't add more bugs.
If you are migrating to 1.0.0 you need to change the following properties.
In the Project's build.gradle file you need to replace minifyEnabled.
Hence your new build type should be
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
Also make sure that gradle version is 1.0.0 like
classpath 'com.android.tools.build:gradle:1.0.0'
in the build.gradle file.
This should solve the problem.

An alternative solution uses the stash:
Before:
~/dev/gitpro $git stash list
~/dev/gitpro $git log --oneline -3
* 7049dd5 (HEAD -> master) c111
* 3f1fa3d c222
* 0a0f6c4 c333
note you cannot run 'git stash pop' without specifying the stash@{1} entry. The stash is a LIFO stack -- not FIFO -- so that would incorrectly pop the stash@{0} entry with c222's changes (instead of stash@{1} with c111's changes).
note if there are conflicting chunks between commits 111 and 222, then you'll be forced to resolve them when attempting to pop. (This would be the case if you went with an alternative rebase solution as well.)
After:
~/dev/gitpro $git stash list
stash@{0}: On master: c222
~/dev/gitpro $git log -2 --oneline
* edbd9e8 (HEAD -> master) c111
* 0a0f6c4 c333
Need to add to chosen answer: As of now, npm install
in a package directory (containing package.json
) will install devDependencies, whereas npm install -g
will not install them.
Statistic plugins works fine!
Here is a quick case:
Refresh
for whole project or select your project or file and Refresh on selection
for only selection.Dir[File.dirname(__FILE__) + '/../lib/*.rb'].each do |file|
require File.basename(file, File.extname(file))
end
If you don't strip the extension then you may end up requiring the same file twice (ruby won't realize that "foo" and "foo.rb" are the same file). Requiring the same file twice can lead to spurious warnings (e.g. "warning: already initialized constant").
As an addition to @dulgan's answer, it is always a good approach to use firstObject
over objectAtIndex:0
, because while first one returns nil if there is no object in the array, latter one throws exception.
UIViewController *rootViewController = self.navigationController.rootViewController;
Alternatively, it'd be a big plus for you to create a category named UINavigationController+Additions
and define your method in that.
@interface UINavigationController (Additions)

I was getting the same issue in windows. I fixed it by
This is fixed in npm 7. See npm/cli#PR169
You could try turning off the main Activity's ability to save its state (thus making it forget what control had text and what had focus). You will need to have some other way of remembering what your EditText's have and repopulating them onResume(). Launch your sub-Activities with startActivityForResult() and create an onActivityResult() handler in your main Activity that will update the EditText's correctly. This way you can set the proper button you want focused onResume() at the same time you repopulate the EditText's by using a myButton.post(new Runnable(){ run() { myButton.requestFocus(); } });
The View.post() method is useful for setting focus initially because that runnable will be executed after the window is created and things settle down, allowing the focus mechanism to function properly by that time. Trying to set focus during onCreate/Start/Resume() usually has issues, I've found.
Please note this is pseudo-code and non-tested, but it's a possible direction you could try.
