select REPLACE (' Hello , How Are You ?', ' ', '' )
I've just checked
$scope.$parent.someProperty
works for me.
and it will be
{{$parent.someProperty}}
for the view.
if you dont have apparmor or selinux issues, but still get errorcode 13's:
mysql must be able to access the full path. I.e. all folders must be mysql accessible, not just the one you intend in pointing to.
example, you try using this in your mysql configuration: tmp = /some/folder/on/disk
# will work, as user root:
mkdir -p /some/folder/on/disk
chown -R mysql:mysql /some
# will not work, also as user root:
mkdir -p /some/folder/on/disk
chown -R mysql:mysql /some/folder/on/disk
Building on @blak3r's answer, here's a bit of shorthand I use in case it helps other diagnose:
If you're trying to debug a Node.js script that is running out of file descriptors here's a line to give you the output of lsof
used by the node process in question:
openFiles = child_process.execSync(`lsof -p ${process.pid}`);
This will synchronously run lsof
filtered by the current running Node.js process and return the results via buffer.
Then use console.log(openFiles.toString())
to convert the buffer to a string and log the results.
You can use coprocessor what is available since HBase 0.92. See Coprocessor and AggregateProtocol and example

Why Access-Control-Allow-Headers

values are super long?
Those do not support the *
syntax, so I've collected the most common (and exotic) headers from around the web, in various formats #1 #2 #3 (and I will update the list from time to time)
Why do you use Header unset ______
syntax?
GoDaddy servers (which my website is hosted on..) have a weird bug where if the headers are already set, the previous value will join the existing one.. (instead of replacing it) this way I "pre-clean" existing values (really just a a quick && dirty solution)
Is it safe for me to use 'as-is'?
Well.. mostly the answer would be YES since the .htaccess
is limiting the headers to the scripts (PHP, HTML, ...) and resources (.JPG, .JS, .CSS) served from the following "folder"-location. You optionally might want to remove the Access-Control-Allow-Methods
lines. Also Connection
, Time-Zone
, Keep-Alive
and DNT
, Accept-Ranges
, Vary
, X-UA-Compatible
, X-Frame-Options
, X-Content-Type-Options
and X-Xss-Protection
are just a suggestion I'm using for my online-service.. feel free to remove those too...

You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.
Late answer, but two things to add:
'ColorOrder'
property and how to set a global default with 'DefaultAxesColorOrder'
, see the "Appendix" at the bottom of this post.The ColorOrder
axes
property allows MATLAB to automatically cycle through a list of colors when using hold on/all
(again, see Appendix below for how to set
/get
the ColorOrder
for a specific axis or globally via DefaultAxesColorOrder
). However, by default MATLAB only specifies a short list of colors (just 7 as of R2013b) to cycle through, and on the other hand it can be problematic to find a good set of colors for more data series. For 10 plots, you obviously cannot rely on the default ColorOrder
.
A great way to define N visually distinct colors is with the "Generate Maximally Perceptually-Distinct Colors" (GMPDC) submission on the MATLAB Central File File Exchange. It is best described in the author's own words:
This function generates a set of colors which are distinguishable by reference to the "Lab" color space, which more closely matches human color perception than RGB. Given an initial large list of possible colors, it iteratively chooses the entry in the list that is farthest (in Lab space) from all previously-chosen entries.
For example, when 25 colors are requested:
The GMPDC submission was chosen on MathWorks' official blog as Pick of the Week in 2010 in part because of the ability to request an arbitrary number of colors (in contrast to MATLAB's built in 7 default colors). They even made the excellent suggestion to set MATLAB's ColorOrder
on startup to,
distinguishable_colors(20)
Of course, you can set the ColorOrder
for a single axis or simply generate a list of colors to use in any way you like. For example, to generate 10 "maximally perceptually-distinct colors" and use them for 10 plots on the same axis (but not using ColorOrder
, thus requiring a loop):
% Starting with X of size N-by-P-by-2, where P is number of plots
mpdc10 = distinguishable_colors(10) % 10x3 color list
hold on
for ii=1:size(X,2),
plot(X(:,ii,1),X(:,ii,2),'.','Color',mpdc10(ii,:));
end
The process is simplified, requiring no for
loop, with the ColorOrder
axis property:
% X of size N-by-P-by-2 mpdc10 = distinguishable_colors(10) ha = axes; hold(ha,'on') set(ha,'ColorOrder',mpdc10) % --- set ColorOrder HERE --- plot(X(:,:,1),X(:,:,2),'-.') % loop NOT needed, 'Color' NOT needed. Yay!
APPENDIX
To get the ColorOrder
RGB array used for the current axis,
get(gca,'ColorOrder')
To get the default ColorOrder
for new axes,
get(0,'DefaultAxesColorOrder')
Example of setting new global ColorOrder
with 10 colors on MATLAB start, in startup.m
:
set(0,'DefaultAxesColorOrder',distinguishable_colors(10))

With SQLServer 2005 Express, what I found was that even with autocommit off, insertions into a Db table were committed without my actually issuing a commit command from the Management Studio session. The only difference was, when autocommit was off, I could roll back all the insertions; with *autocommit on, I could not.* Actually, I was wrong. With autocommit mode off, I see the changes only in the QA (Query Analyzer) window from which the commands were issued. If I popped a new QA (Query Analyzer) window, I do not see the changes made by the first window (session), i.e. they are NOT committed! I had to issue explicit commit or rollback commands to make changes visible to other sessions(QA windows) -- my bad! Things are working correctly.

Because it makes these things so easy, you could consider using a JavaScript library like jQuery to do this:
<script>
$(document).ready(function() {
$('img.thumbnail').click(function() {
window.location.href = this.id + '.html';
});
});
</script>
Basically, it attaches an onClick
event to all images with class thumbnail
to redirect to the corresponding HTML page (id
+ .html
). Then you only need the images in your HTML (without the a
elements), like this:
<img src="bottle.jpg" alt="bottle" class="thumbnail" id="bottle" />
<img src="glass.jpg" alt="glass" class="thumbnail" id="glass" />
in oracle you can use
desc users
to display all columns containing in users table
Another better way of doing it:
:LOOP
timeout /T 1 /NOBREAK
::pause or sleep x seconds also valid
call myLabel
if not ErrorLevel 1 goto :LOOP
This way you can take care of errors too
Just to add on these answers is that, mod_php is the oldest and slowest method available in HTTPD server to use PHP. It is not recommended, unless you are running old versions of Apache HTTPD and PHP. php-fpm and proxy_cgi are the preferred methods.

First of all shuffling
is the process of transfering data from the mappers to the reducers, so I think it is obvious that it is necessary for the reducers, since otherwise, they wouldn't be able to have any input (or input from every mapper). Shuffling can start even before the map phase has finished, to save some time. That's why you can see a reduce status greater than 0% (but less than 33%) when the map status is not yet 100%.
Sorting
saves time for the reducer, helping it easily distinguish when a new reduce task should start. It simply starts a new reduce task, when the next key in the sorted input data is different than the previous, to put it simply. Each reduce task takes a list of key-value pairs, but it has to call the reduce() method which takes a key-list(value) input, so it has to group values by key. It's easy to do so, if input data is pre-sorted (locally) in the map phase and simply merge-sorted in the reduce phase (since the reducers get data from many mappers).
Partitioning
, that you mentioned in one of the answers, is a different process. It determines in which reducer a (key, value) pair, output of the map phase, will be sent. The default Partitioner uses a hashing on the keys to distribute them to the reduce tasks, but you can override it and use your own custom Partitioner.
A great source of information for these steps is this Yahoo tutorial (archived).
A nice graphical representation of this is the following (shuffle is called "copy" in this figure):
Note that shuffling
and sorting
are not performed at all if you specify zero reducers (setNumReduceTasks(0)). Then, the MapReduce job stops at the map phase, and the map phase does not include any kind of sorting (so even the map phase is faster).
UPDATE: Since you are looking for something more official, you can also read Tom White's book "Hadoop: The Definitive Guide". Here is the interesting part for your question.
Tom White has been an Apache Hadoop committer since February 2007, and is a member of the Apache Software Foundation, so I guess it is pretty credible and official...

To make it work in JSON, you need to escape a few more character than that.
myString.replace("\\", "\\\\")
.replace("\"", "\\\"")
.replace("\r", "\\r")
.replace("\n", "\\n")
and if you want to be able to use json2.js
to parse it then you also need to escape
.replace("\u2028", "\\u2028")
.replace("\u2029", "\\u2029")
which JSON allows inside quoted strings, but which JavaScript does not.
Someone correct me if this is bad, but I like to lock everything down as much as possible, and if you've only got one target for uploads (as it usually the case), then just target your changes to that one file. This works for me on the Ubuntu nginx-extras mainline 1.7+ package:
location = /upload.php {
client_max_body_size 102M;
fastcgi_param PHP_VALUE "upload_max_filesize=102M \n post_max_size=102M";
(...)
}

It means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.
You can also use this script , just change the height and width

<script>
var canvas = document.getElementById("Canvas01");
var ctx = canvas.getContext("2d");
The behaviour comes from the fact that in Python prior to version 3 bytes

- completely new type, not backwards compatible.
If this is really bothering you, why not write your own method isBetween(orderBean.getFiles().size(),0,5)

Another option is to use isEmpty
as it is a tad clearer:
if(!orderBean.getFiles().isEmpty() && orderBean.getFiles().size() < 5)

I just wanted to share something with you.
I got some hard time with ng-mouseenter
and ng-mouseleave
events.
The case study:
I created a floating navigation menu which is toggle when the cursor is over an icon.
This menu was on top of each page.
ng-class="{down: vm.isHover}"
ng-mouseenter="vm.isHover = true"
ng-mouseleave="vm.isHover = false"
For now, everything was fine and worked as expected.
The solution is clean and simple.
The incoming problem:
In a specific view, I have a list of elements.
I added an action panel when the cursor is over an element of the list.
I used the same code as above to handle the behavior.
The problem:
I figured out when my cursor is on the floating navigation menu and also on the top of an element, there is a conflict between each other.
The action panel showed up and the floating navigation was hide.
The thing is that even if the cursor is over the floating navigation menu, the list element ng-mouseenter is triggered.
It makes no sense to me, because I would expect an automatic break of the mouse propagation events.
I must say that I was disappointed and I spend some time to find out that problem.
First thoughts:
I tried to use these :
$event.stopPropagation()
$event.stopImmediatePropagation()
I combined a lot of ng pointer events (mousemove, mouveover, ...) but none help me.
CSS solution:
I found the solution with a simple css property that I use more and more:
pointer-events: none;
Basically, I use it like that (on my list elements):
ng-style="{'pointer-events': vm.isHover ? 'none' : ''}"
With this tricky one, the ng-mouse events will no longer be triggered and my floating navigation menu will no longer close himself when the cursor is over it and over an element from the list.
To go further:
As you may expect, this solution works but I don't like it.
We do not control our events and it is bad.
Plus, you must have an access to the vm.isHover
scope to achieve that and it may not be possible or possible but dirty in some way or another.
I could make a fiddle if someone want to look.
Nevertheless, I don't have another solution...
It's a long story and I can't give you a potato so please forgive me my friend.
Anyway, pointer-events: none
is life, so remember it.

According to me the best way of dealing with such problems and avoiding couple of condition required for checking the the height of device, is using the relative frame for views or any UI element which you are adding to you view for example: if you are adding some UI element which you want should at the bottom of view or just above tab bar then you should take the y origin with respect to your view's height or with respect to tab bar (if present) and we have auto resizing property as well. I hope this will work for you

Assign your image to a string. Eg image Now set icon to a fixed size label.
image.setIcon(new javax.swing.ImageIcon(image.getScaledInstance(50,50,WIDTH)));
Use tow function to solve it ,Very simple and useful:
HTML:
<input class="int-number" type="text" />
<input class="decimal-number" type="text" />
JQuery:
//Integer Number
$(document).on("input", ".int-number", function (e) {
this.value = this.value.replace(/[^0-9]/g, '');
});
//Decimal Number
$(document).on("input", ".decimal-number", function (e) {
this.value = this.value.replace(/[^0-9.]/g, '').replace(/(\..*)\./g, '$1');
});
You can also create border with the color of your wish..
view.layer.borderColor = [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:1.0].CGColor;
*r,g,b are the values between 0 to 255.
What I usually do is add two key-value properties to the Info.plist
file.

How about this?
>>> import numpy
>>> test1 = numpy.array([1,23,4,6,7,8])
>>> forward = iter(test1)
>>> backward = reversed(test1)
>>> for a in range((len(test1)+1)//2):
... print forward.next(), backward.next()
...
1 8
23 7
4 6
The (len(test1)+1)//2
ensures that the middle element of odd length arrays is also returned:
>>> test1 = numpy.array([1,23,4,9,6,7,8]) # additional element '9' in the middle
>>> forward = iter(test1)
>>> backward = reversed(test1)
>>> for a in range((len(test1)+1)//2):
... print forward.next(), backward.next()
1 8
23 7
4 6
9 9
Using just len(test1)//2
will drop the middle elemen of odd length arrays.

There are 3 things you need.
You need to oAuth with the owner of those photos. (with the 'user_photos' extended permission)
You need the access token (which you get returned in the URL box after the oAuth is done.)
When those are complete you can then access the photos like so https://graph.facebook.com/me?access_token=ACCESS_TOKEN
You can find all of the information in more detail here: http://developers.facebook.com/docs/authentication
new Date().toString();
http://www.mkyong.com/java/java-how-to-get-current-date-time-date-and-calender/
Dateformatter can make it to any string you want
Here is how it works for me with no Servlet use.
Let's say I am trying to access web.xml in project/WebContent/WEB-INF/web.xml
In project property Source-tab add source folder by pointing to the parent container for WEB-INF folder (in my case WebContent )
Now let's use class loader:
InputStream inStream = class.getClass().getClassLoader().getResourceAsStream("Web-INF/web.xml")
$("#closeLink").click(closeIt);
Let's say you want to call your function passing some args to it i.e., closeIt(1, false)
. Then, you should build an anonymous function and call closeIt
from it.
$("#closeLink").click(function() {
closeIt(1, false);
});
This Problem can be solved without using for loop.Single line code will be sufficient for this. Using Nested Map with lambda function will also works here.
l = [['40', '20', '10', '30'], ['20', '20', '20', '20', '20', '30', '20'], ['30', '20', '30', '50', '10', '30', '20', '20', '20'], ['100', '100'], ['100', '100', '100', '100', '100'], ['100', '100', '100', '100']]
map(lambda x:map(lambda y:float(y),x),l)
And Output List would be as follows:
[[40.0, 20.0, 10.0, 30.0], [20.0, 20.0, 20.0, 20.0, 20.0, 30.0, 20.0], [30.0, 20.0, 30.0, 50.0, 10.0, 30.0, 20.0, 20.0, 20.0], [100.0, 100.0], [100.0, 100.0, 100.0, 100.0, 100.0], [100.0, 100.0, 100.0, 100.0]]
The logic is simple. setOnClickListener
belongs to step 2.
OnClickListener
* like it's done in that example and override the onClick
-method.OnClickListener
to that button using btn.setOnClickListener(myOnClickListener);
in your fragments/activities onCreate
-method.onClick
function of the assigned OnClickListener
is called.*If you import android.view.View;
you use View.OnClickListener
. If you import android.view.View.*;
or import android.view.View.OnClickListener;
you use OnClickListener
as far as I get it.
Another way is to let you activity/fragment inherit from OnClickListener
. This way you assign your fragment/activity as the listener for your button and implement onClick
as a member-function.
In my case the issue was missing Android SDK Command-line tools
All of these are returning equals. They arent actually doing a comparison, which is useful for sort. This will behave more like a comparator:
private static final Comparator stringFallbackComparator = new Comparator() {
public int compare(Object o1, Object o2) {
if (!(o1 instanceof Comparable))
o1 = o1.toString();
if (!(o2 instanceof Comparable))
o2 = o2.toString();
return ((Comparable)o1).compareTo(o2);
}
};
public int compare(Map m1, Map m2) {
TreeSet s1 = new TreeSet(stringFallbackComparator); s1.addAll(m1.keySet());
TreeSet s2 = new TreeSet(stringFallbackComparator); s2.addAll(m2.keySet());
Iterator i1 = s1.iterator();
Iterator i2 = s2.iterator();
int i;
while (i1.hasNext() && i2.hasNext())
{
Object k1 = i1.next();
Object k2 = i2.next();
if (0!=(i=stringFallbackComparator.compare(k1, k2)))
return i;
if (0!=(i=stringFallbackComparator.compare(m1.get(k1), m2.get(k2))))
return i;
}
if (i1.hasNext())
return 1;
if (i2.hasNext())
return -1;
return 0;
}
Its Simple to implement Just need javasript methods in your html to get value of html content. As Above your code some changes to be need.
public class htmldecoder extends Activity implements OnClickListener,TextWatcher
{
Button btsubmit; // this button in your xml file
WebView wvbrowser;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.htmldecoder);
btsubmit=(Button)findViewById(R.id.btsubmit);
btsubmit.setOnClickListener(this);
wvbrowser=(WebView)findViewById(R.id.wvbrowser);
wvbrowser.setWebViewClient(new HelloWebViewClient());
wvbrowser.getSettings().setJavaScriptEnabled(true);
wvbrowser.getSettings().setPluginsEnabled(true);
wvbrowser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
MyJavaScriptInterface myinterface=new MyJavaScriptInterface();
wvbrowser.addJavascriptInterface(myinterface,"interface");
webView.loadUrl("file:///android_asset/simple.html"); //use one html file for //testing put your html file in assets. Make sure that you done JavaScript methods to get //values for html content in html file .
}
public void onClick(View v)
{
if(btsubmit==v)
{
webView.loadUrl("javascript:showalert()");// call javascript method.
//wvbr
}
}
final class MyJavaScriptInterface {
MyJavaScriptInterface() {
}
public void sendValueFromHtml(String value) {
System.out.println("Here is the value from html::"+value);
}
}
}
Your Javascript in html
<script type="text/javascript">
//<![CDATA[
var n1;
function callme(){
n1=document.getElementById("FacadeAL").value;
}
function showalert(){
window.interface.sendValueFromHtml(n1);// this method calling the method of interface which //you attached to html file in android. // & we called this showalert javasript method on //submmit buttton click of android.
}
//]]>
</script>
& Make sure you calling callme like below in html
<input name="FacadeAL" id="FacadeAL" type="text" size="5" onblur="callme()"/>
Hope this will help you.
URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.
There are several ways to soften the pain:
JSF EL offers a shorthand to ${pageContext.request}
in flavor of #{request}
:
<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>
You can if necessary use <c:set>
tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:
<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>
JSF 2.x offers the <h:link>
which can take a view ID relative to the context root in outcome
and it will append the context path and FacesServlet
mapping automatically:
<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>
HTML offers the <base>
tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>
.
<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>
(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring()
, see also this answer)
This should end up in the generated HTML something like as
<base href="http://example.com/webname/" />
Note that the <base>
tag has a caveat: it makes all jump anchors in the page like <a href="#top">
relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a>
or <h:link value="top" fragment="top" />
.
Inset of getBitmap
which is depricated now I use the following approach in Kotlin
PICK_IMAGE_REQUEST ->
data?.data?.let {
val bitmap = BitmapFactory.decodeStream(contentResolver.openInputStream(it))
imageView.setImageBitmap(bitmap)
}
I would try to give them all display: block;
attribute and using float: left;
.
You can then set width
and/or height
as you like. You can even specify some vertical-alignment rules.

In the case you mention, it doesn't affect callers of your API, which is why it's not commonly done (and isn't necessary in the header). It only affects the implementation of your function.
It's not particularly a bad thing to do, but the benefits aren't that great given that it doesn't affect your API, and it adds typing, so it's not usually done.
This displays the name of the current user:
Function Username() As String
Username = Application.Username
End Function
The property Application.Username
holds the name entered with the installation of MS Office.
Enter this formula in a cell:
=Username()
Just in case anyone else encounters the same problems.
Note, that relations are required to be camelcase. So in my case available_videos() should have been availableVideos().
You can easily find out investigating the Laravel source:
// Illuminate\Database\Eloquent\Model.php
...
/**
* Get an attribute from the model.
*
* @param string $key
* @return mixed
*/
public function getAttribute($key)
{
$inAttributes = array_key_exists($key, $this->attributes);
// If the key references an attribute, we can just go ahead and return the
// plain attribute value from the model. This allows every attribute to
// be dynamically accessed through the _get method without accessors.
if ($inAttributes || $this->hasGetMutator($key))
{
return $this->getAttributeValue($key);
}
// If the key already exists in the relationships array, it just means the
// relationship has already been loaded, so we'll just return it out of
// here because there is no need to query within the relations twice.
if (array_key_exists($key, $this->relations))
{
return $this->relations[$key];
}
// If the "attribute" exists as a method on the model, we will just assume
// it is a relationship and will load and return results from the query
// and hydrate the relationship's value on the "relationships" array.
$camelKey = camel_case($key);
if (method_exists($this, $camelKey))
{
return $this->getRelationshipFromMethod($key, $camelKey);
}
}
This also explains why my code worked, whenever I loaded the data using the load() method before.
Anyway, my example works perfectly okay now, and $model->availableVideos always returns a Collection.
im
is "image process name"
example /f /im notepad.exe
is specified to kill image process name (program) notepad.exe
Another way (worked for 2015) is open "Install/remove programs" (Apps & features), find Visual Studio, select Modify. In opened window, press Modify, check
Languages -> Visual C++ -> Common tools for Visual C++
Windows and web development -> Tools for universal windows apps -> Tools (1.4.1)
and Windows 10 SDK ([version])
Windows and web development -> Tools for universal windows apps -> Windows 10 SDK ([version])
and install. Then right click on solution -> Re-target and it will compile
Q: What is the difference between RDL and RDLC formats?
A: RDL files are created by the SQL Server 2005 version of Report Designer. RDLC files are created by the Visual Studio 2008 version of Report Designer.
RDL and RDLC formats have the same XML schema. However, in RDLC files, some values (such as query text) are allowed to be empty, which means that they are not immediately ready to be published to a Report Server. The missing values can be entered by opening the RDLC file using the SQL Server 2005 version of Report Designer. (You have to rename .rdlc to .rdl first.)
RDL files are fully compatible with the ReportViewer control runtime. However, RDL files do not contain some information that the design-time of the ReportViewer control depends on for automatically generating data-binding code. By manually binding data, RDL files can be used in the ReportViewer control. New! See also the RDL Viewer sample program.
Note that the ReportViewer control does not contain any logic for connecting to databases or executing queries. By separating out such logic, the ReportViewer has been made compatible with all data sources, including non-database data sources. However this means that when an RDL file is used by the ReportViewer control, the SQL related information in the RDL file is simply ignored by the control. It is the host application's responsibility to connect to databases, execute queries and supply data to the ReportViewer control in the form of ADO.NET DataTables.

First we should know the order of execution of Clauses i.e FROM > WHERE > GROUP BY > HAVING > DISTINCT > SELECT > ORDER BY. Since WHERE Clause gets executed before GROUP BY Clause the records cannot be filtered by applying WHERE to a GROUP BY applied records.
"HAVING is same as the WHERE clause but is applied on grouped records".
first the WHERE clause fetches the records based on the condition then the GROUP BY clause groups them accordingly and then the HAVING clause fetches the group records based on the having condition.
Create the hash:
hash = {:item1 => 1}
Add a new item to it:
hash[:item2] = 2
You can try this:
select * FROM table where (concat(first_name, ' ', last_name)) = $search_term;
There are three options, that you can use. -I
is to exclude binary files in grep. Other are for line numbers and file names.
grep -I -n -H
-I -- process a binary file as if it did not contain matching data;
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match
So this might be a way to run grep:
grep -InH your-word *
This worked for me:
string string_test = "80123456";
unsigned long x;
signed long val;
std::stringstream ss;
ss << std::hex << string_test;
ss >> x;
// ss >> val; // if I try this val = 0
val = (signed long)x; // However, if I cast the unsigned result I get val = 0x80123456
Generally the practice would be to pass data as a DateTime with a "timezone" of UTC and then pass a TimeZoneInfo object and when you are ready to display the data, you use the TimeZoneInfo object to convert the UTC DateTime.
The other option is to set the DateTime with the current timezone, and then make sure the "timezone" is unknown for the DateTime object, then make sure the DateTime is again passed with a TimeZoneInfo that indicates the TimeZone of the DateTime passed.
As others have indicated here, it would be nice if Microsoft got on top of this and created one nice object to do it all, but for now you have to deal with two objects.
If you are using storyboards you could set the navigation bar tint colour.
$('#submenu li').hover(function(){
$('#carousel').css('backgroundPosition', newValue);
});
I believe classification is classifying records in a data set into predefined classes or even defining classes on the go. I look at it as pre-requisite for any valuable data mining, I like to think of it at unsupervised learning i.e. one does not know what he/she is looking for while mining the data and classification serves as a good starting point
Clustering on the other end falls under supervised learning i.e. one know what parameters to look for, the correlation between them along with critical levels. I believe it requires some understanding of statistics and maths
I was getting this error on amazon.ca, meetup.com, and the Symantec homepage.
I went to the update page in the Chrome browser (it was at 53.*) and checked for an upgrade, and it showed there was no updates available. After asking around my office, it turns out the latest version was 55 but I was stuck on 53 for some reason.
After upgrading (had to manually download from the Chrome website) the issues were gone!
Using Classes in Node -
Here we are requiring the ReadWrite module and calling a makeObject(), which returns the object of the ReadWrite class. Which we are using to call the methods. index.js
const ReadWrite = require('./ReadWrite').makeObject();
const express = require('express');
const app = express();
class Start {
constructor() {
const server = app.listen(8081),
host = server.address().address,
port = server.address().port
console.log("Example app listening at http://%s:%s", host, port);
console.log('Running');
}
async route(req, res, next) {
const result = await ReadWrite.readWrite();
res.send(result);
}
}
const obj1 = new Start();
app.get('/', obj1.route);
module.exports = Start;
ReadWrite.js
Here we making a makeObject method, which makes sure that a object is returned, only if a object is not available.
class ReadWrite {
constructor() {
console.log('Read Write');
this.x;
}
static makeObject() {
if (!this.x) {
this.x = new ReadWrite();
}
return this.x;
}
read(){
return "read"
}
write(){
return "write"
}
async readWrite() {
try {
const obj = ReadWrite.makeObject();
const result = await Promise.all([ obj.read(), obj.write()])
console.log(result);
check();
return result
}
catch(err) {
console.log(err);
}
}
}
module.exports = ReadWrite;

First of all, your description is misleading. Double
is a floating point data type. You presumably want to pad your digits with leading zeros in a string. The following code does that:
$s = sprintf('%02d', $digit);
For more information, refer to the documentation of sprintf
.
Is there a Clear() method on the DataTable class??
I think there is. If there is, use that.
String sc1="0.0";
Double s1=Double.parseDouble(sc1.toString());
I think it's important to note another difference between Sort
and OrderBy
:
Suppose there exists a Person.CalculateSalary()
method, which takes a lot of time; possibly more than even the operation of sorting a large list.
Compare
// Option 1
persons.Sort((p1, p2) => Compare(p1.CalculateSalary(), p2.CalculateSalary()));
// Option 2
var query = persons.OrderBy(p => p.CalculateSalary());
Option 2 may have superior performance, because it only calls the CalculateSalary
method n times, whereas the Sort
option might call CalculateSalary
up to 2n log(n) times, depending on the sort algorithm's success.
I ran into a case where I got that error message and had
Foo foo(Bar());
and was basically trying to pass in a temporary Bar object to the Foo constructor. Turns out the compiler was translating this to
Foo foo(Bar(*)());
that is, a function declaration whose name is foo that returns a Foo that takes in an argument -- a function pointer returning a Bar with 0 arguments. When passing in temporaries like this, better to use Bar{}
instead of Bar()
to eliminate ambiguity.
Short answer:
let pageModified = true
window.addEventListener("beforeunload",
() => pageModified ? 'Close page without saving data?' : null
)
Also you can use Kotlinx features
val hView = nav_view.getHeaderView(0)
hView.textViewName.text = "lorem ipsum"
hView.imageView.setImageResource(R.drawable.ic_menu_gallery)
Just Delete the (obj)Object folder in project folder then Run the application then It will work fine. Steps:
this might be a very old question but with pandas we have a very easy solution
import pandas as pd
data=pd.read_csv('all16.csv',skiprows=1)
data['column'].min()
with skiprows=1 we can skip the first row then we can find the least value using data['column'].min()

Goto
s are universally reviled in computer science and programming as they lead to very unstructured code.
Python (like almost every programming language today) supports structured programming which controls flow using if/then/else, loop and subroutines.
The key to thinking in a structured way is to understand how and why you are branching on code.
For example, lets pretend Python had a goto
and corresponding label
statement shudder. Look at the following code. In it if a number is greater than or equal to 0 we print if it
number = input()
if number < 0: goto negative
if number % 2 == 0:
print "even"
else:
print "odd"
goto end
label: negative
print "negative"
label: end
print "all done"
If we want to know when a piece of code is executed, we need to carefully traceback in the program, and examine how a label was arrived at - which is something that can't really be done.
For example, we can rewrite the above as:
number = input()
goto check
label: negative
print "negative"
goto end
label: check
if number < 0: goto negative
if number % 2 == 0:
print "even"
else:
print "odd"
goto end
label: end
print "all done"
Here, there are two possible ways to arrive at the "end", and we can't know which one was chosen. As programs get large this kind of problem gets worse and results in spaghetti code
In comparison, below is how you would write this program in Python:
number = input()
if number >= 0:
if number % 2 == 0:
print "even"
else:
print "odd"
else:
print "negative"
print "all done"
I can look at a particular line of code, and know under what conditions it is met by tracing back the tree of if/then/else
blocks it is in. For example, I know that the line print "odd"
will be run when a ((number >= 0) == True) and ((number % 2 == 0) == False)

You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file
to debug it.
When it starts up, you can use bt
(for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is given a number. You can use frame number
(replacing number with the corresponding number in the stack trace) to select a particular stack frame.
You can then use list
to see code around that function, and info locals
to see the local variables. You can also use print name_of_variable
(replacing "name_of_variable" with a variable name) to see its value.
Typing help
within GDB will give you a prompt that will let you see additional commands.
You can create a new class for removing margin and can apply to the element where you want to remove extra margin:
.margL0 { margin-left:0 !important }
!important : it will help you to remove the default margin or overwrite the current margin value
and apply to that div from in which you want to remove the margin from left side
I'd probably go with this (I know its not pure linq), keep a reference to the original list if you want to retain all items, and you should find the updated values are in there:
foreach (var mc in list.Where(x => x.Name == "height"))
mc.Value = 30;
Try this
SELECT Count(*) AS N
FROM
(SELECT DISTINCT Name FROM table1) AS T;

For Java 11 (JDK 11) it can be located with the following command:

Add your multiple columns with comma separations:
UPDATE settings SET postsPerPage = $postsPerPage, style= $style WHERE id = '1'
However, you're not sanitizing your inputs?? This would mean any random hacker could destroy your database. See this question: What's the best method for sanitizing user input with PHP?
Also, is style a number or a string? I'm assuming a string, so it would need to be quoted.
Or you can do
docker run -v /var/volume1 -v /var/volume2 DATA busybox true
I usually use this workaround:
try:
from .mymodule import myclass
except Exception: #ImportError
from mymodule import myclass
Which means your IDE should pick up the right code location and the python interpreter will manage to run your code.
frameLayout.addView(yourView); <----- if you are getting error on this line remove view from it's parent first
if (yourView.getParent() != null)
((ViewGroup) yourView.getParent()).removeView(yourView); frameLayout.addView(yourView); (Add view to layout)
The original code is from Sabry Suleiman.
Made it a bit prettier:
function is_session_started() {
if ( php_sapi_name() === 'cli' )
return false;
return version_compare( phpversion(), '5.4.0', '>=' )
? session_status() === PHP_SESSION_ACTIVE
: session_id() !== '';
}
First condition checks the Server API in use. If Command Line Interface is used, the function returns false.
Then we return the boolean result depending on the PHP version in use.
In ancient history you simply needed to check session_id()
. If it's an empty string, then session is not started. Otherwise it is.
Since 5.4 to at least the current 8.0 the norm is to check session_status()
. If it's not PHP_SESSION_ACTIVE
, then either the session isn't started yet (PHP_SESSION_NONE
) or sessions are not available altogether (PHP_SESSION_DISABLED
).
Building upon Fabien Kruba's already excellent answer, I thought it would be nice if the **
portion of the URL could be given as a parameter to the controller method via an annotation, in a way which was similar to @RequestParam
and @PathVariable
, rather than always using a utility method which explicitly required the HttpServletRequest
. So here's an example of how that might be implemented. Hopefully someone finds it useful.
Create the annotation, along with the argument resolver:
@Target(ElementType.PARAMETER)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface WildcardParam {
class Resolver implements HandlerMethodArgumentResolver {
@Override
public boolean supportsParameter(MethodParameter methodParameter) {
return methodParameter.getParameterAnnotation(WildcardParam.class) != null;
}
@Override
public Object resolveArgument(MethodParameter methodParameter, ModelAndViewContainer modelAndViewContainer, NativeWebRequest nativeWebRequest, WebDataBinderFactory webDataBinderFactory) throws Exception {
HttpServletRequest request = nativeWebRequest.getNativeRequest(HttpServletRequest.class);
return request == null ? null : new AntPathMatcher().extractPathWithinPattern(
(String) request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE),
(String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE));
}
}
}
Register the method argument resolver:
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) {
resolvers.add(new WildcardParam.Resolver());
}
}
Use the annotation in your controller handler methods to have easy access to the **
portion of the URL:
@RestController
public class SomeController {
@GetMapping("/**")
public void someHandlerMethod(@WildcardParam String wildcardParam) {
// use wildcardParam here...
}
}
Try this. I purposely broke out various parts so you can move things around.
library(sfsmisc)
#Generate the data
x <- 1:100000
y <- 1:100000
#Setup the plot area
par(pty="m", plt=c(0.1, 1, 0.1, 1), omd=c(0.1,0.9,0.1,0.9))
#Plot a blank graph without completing the x or y axis
plot(x, y, type = "n", xaxt = "n", yaxt="n", xlab="", ylab="", log = "x", col="blue")
mtext(side=3, text="Test Plot", line=1.2, cex=1.5)
#Complete the x axis
eaxis(1, padj=-0.5, cex.axis=0.8)
mtext(side=1, text="x", line=2.5)
#Complete the y axis and add the grid
aty <- seq(par("yaxp")[1], par("yaxp")[2], (par("yaxp")[2] - par("yaxp")[1])/par("yaxp")[3])
axis(2, at=aty, labels=format(aty, scientific=FALSE), hadj=0.9, cex.axis=0.8, las=2)
mtext(side=2, text="y", line=4.5)
grid()
#Add the line last so it will be on top of the grid
lines(x, y, col="blue")
If you're dealing with Data Validation lists, you can use the Worksheet_Change event. Right click on the sheet with the data validation and choose View Code. Then type in this:
Private Sub Worksheet_Change(ByVal Target As Range)
MsgBox Target.Value
End Sub
If you're dealing with ActiveX comboboxes, it's a little more complicated. You need to create a custom class module to hook up the events. First, create a class module named CComboEvent and put this code in it.
Public WithEvents Cbx As MSForms.ComboBox
Private Sub Cbx_Change()
MsgBox Cbx.Value
End Sub
Next, create another class module named CComboEvents. This will hold all of our CComboEvent instances and keep them in scope. Put this code in CComboEvents.
Private mcolComboEvents As Collection
Private Sub Class_Initialize()
Set mcolComboEvents = New Collection
End Sub
Private Sub Class_Terminate()
Set mcolComboEvents = Nothing
End Sub
Public Sub Add(clsComboEvent As CComboEvent)
mcolComboEvents.Add clsComboEvent, clsComboEvent.Cbx.Name
End Sub
Finally, create a standard module (not a class module). You'll need code to put all of your comboboxes into the class modules. You might put this in an Auto_Open procedure so it happens whenever the workbook is opened, but that's up to you.
You'll need a Public variable to hold an instance of CComboEvents. Making it Public will kepp it, and all of its children, in scope. You need them in scope so that the events are triggered. In the procedure, loop through all of the comboboxes, creating a new CComboEvent instance for each one, and adding that to CComboEvents.
Public gclsComboEvents As CComboEvents
Public Sub AddCombox()
Dim oleo As OLEObject
Dim clsComboEvent As CComboEvent
Set gclsComboEvents = New CComboEvents
For Each oleo In Sheet1.OLEObjects
If TypeName(oleo.Object) = "ComboBox" Then
Set clsComboEvent = New CComboEvent
Set clsComboEvent.Cbx = oleo.Object
gclsComboEvents.Add clsComboEvent
End If
Next oleo
End Sub
Now, whenever a combobox is changed, the event will fire and, in this example, a message box will show.
You can see an example at https://www.dropbox.com/s/sfj4kyzolfy03qe/ComboboxEvents.xlsm
Not only strings are immutable reference types. Multi-cast delegates too. That is why it is safe to write
protected void OnMyEventHandler()
{
delegate handler = this.MyEventHandler;
if (null != handler)
{
handler(this, new EventArgs());
}
}
I suppose that strings are immutable because this is the most safe method to work with them and allocate memory. Why they are not Value types? Previous authors are right about stack size etc. I would also add that making strings a reference types allow to save on assembly size when you use the same constant string in the program. If you define
string s1 = "my string";
//some code here
string s2 = "my string";
Chances are that both instances of "my string" constant will be allocated in your assembly only once.
If you would like to manage strings like usual reference type, put the string inside a new StringBuilder(string s). Or use MemoryStreams.
If you are to create a library, where you expect a huge strings to be passed in your functions, either define a parameter as a StringBuilder or as a Stream.
I'm using JUnit 5 and for me the problem was that I had imported Test
from the wrong package:
import org.junit.Test;
Replacing it with the following worked for me:
import org.junit.jupiter.api.Test;
I used this code to add something to my request.
$req->query->add(['key'=>'variable']);
$req->request->add(['key'=>'variable']);
you can also covert int to str first and assign index to it then again convert it to int like this:
int(str(x)[n]) //where x is an integer value
This is also MySQL Specific:
show fields from [tablename];
this doesnt just show the table names but it also pulls out all the info about the fields.

You use the Headers
property with a string index:
request.Headers["X-My-Custom-Header"] = "the-value";
According to MSDN, this has been available since:
https://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.headers(v=vs.110).aspx
DateTime.Now.Tostring();
. You can supply parameters to To string function in a lot of ways like given in this link http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm
This will be a lot useful. If you reside somewhere else than the regular format (MM/dd/yyyy)
use always MM not mm, mm gives minutes and MM gives month.
If you don't use Java 8 and you don't want to use a explicit loop for some reason, try MapUtils.populateMap
from Apache Commons.
Say you have a list of Pair
s.
List<ImmutablePair<String, String>> pairs = ImmutableList.of(
new ImmutablePair<>("A", "aaa"),
new ImmutablePair<>("B", "bbb")
);
And you now want a Map of the Pair
's key to the Pair
object.
Map<String, Pair<String, String>> map = new HashMap<>();
MapUtils.populateMap(map, pairs, new Transformer<Pair<String, String>, String>() {
@Override
public String transform(Pair<String, String> input) {
return input.getKey();
}
});
System.out.println(map);
gives output:
{A=(A,aaa), B=(B,bbb)}
That being said, a for
loop is maybe easier to understand. (This below gives the same output):
Map<String, Pair<String, String>> map = new HashMap<>();
for (Pair<String, String> pair : pairs) {
map.put(pair.getKey(), pair);
}
System.out.println(map);
It must be: server.servlet.context-path = / demo note that it does not have quotes only the value preceded by '/' this value goes in your application.properties file
Rather than using if statements might I suggest using a switch instead, I try to avoid using if statements when possible.
var result = MessageBox.Show(@"Do you want to save the changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
switch (result)
{
case DialogResult.Yes:
SaveChanges();
break;
case DialogResult.No:
Rollback();
break;
default:
break;
}
As others have mentioned in this and other similar threads, the best way to avoid this problem is to use RGBA/HSLA or else use a transparent PNG.
But, if you want a ridiculous solution, similar to the one linked in another answer in this thread (which is also my website), here's a brand new script I wrote that fixes this problem automatically, called thatsNotYoChild.js:
http://www.impressivewebs.com/fixing-parent-child-opacity/
Basically it uses JavaScript to remove all children from the parent div, then reposition the child elements back to where they should be without actually being children of that element anymore.
To me, this should be a last resort, but I thought it would be fun to write something that did this, if anyone wants to do this.
Here is a solution for ES6 where you only want to keep the last item. This solution is functional and Airbnb style compliant.
const things = {
thing: [
{ place: 'here', name: 'stuff' },
{ place: 'there', name: 'morestuff1' },
{ place: 'there', name: 'morestuff2' },
],
};
const removeDuplicates = (array, key) => {
return array.reduce((arr, item) => {
const removed = arr.filter(i => i[key] !== item[key]);
return [...removed, item];
}, []);
};
console.log(removeDuplicates(things.thing, 'place'));
// > [{ place: 'here', name: 'stuff' }, { place: 'there', name: 'morestuff2' }]
I just had the same problem, and also found that the line would only display if I put in bad data (characters instead of numbers). This caused the line to appear, but changing back to valid data caused it to disappear again.
What I found is that if I double-clicked the line (appearing with bad data), it showed me that it was on the SECONDARY axis for some reason. Changing that to PRIMARY axis solved my problem.
What is happening is that next(a)
returns the next value of a, which is printed to the console because it is not affected.
What you can do is affect a variable with this value:
>>> a = iter(list(range(10)))
>>> for i in a:
... print(i)
... b=next(a)
...

JointJS/Rappid supports this use case with its Kitchensink example which supports dragging and dropping of elements, and repositioning of connections. It has many examples.
This answer is based off of Vainbhav Jain's answer.
Uncommenting the following line in host file worked for me,
#127.0.0.1 localhost
XAMPP for linux and mac comes with ProFTPD. Make sure to start the service from XAMPP control panel -> manage servers.
Further complete instructions can be found at localhost XAMPP dashboard -> How-to guides -> Configure FTP Access. I have pasted them below :
Open a new Linux terminal and ensure you are logged in as root.
Create a new group named ftp. This group will contain those user accounts allowed to upload files via FTP.
groupadd ftp
usermod -a -G ftp susan
cd /opt/lampp chown root.ftp htdocs chmod 775 htdocs
You can now transfer files to the XAMPP server using the steps below:
If you’re connecting to the server from the same system, use "127.0.0.1" as the host address. If you’re connecting from a different system, use the network hostname or IP address of the XAMPP server.
Use "21" as the port.
Enter your Linux username and password as your FTP credentials.
Your FTP client should now connect to the server and enter the /opt/lampp/htdocs/ directory, which is the default Web server document root.
Once the file is successfully transferred, you should be able to see it in action.
I usually do this and works always.
/try this/
for (i = res; i < *size-1; i++) {
arrb[i] = arrb[i + 1];
}
*size = *size - 1; /*in some ides size -- could give problems*/
Import package is for better readability;
Fully qualified class has to be used in special scenarios. For example, same class name in different package, or use reflect such as Class.forName()
.
In my case the route in my router was:
Route::post('/new-order', 'Api\OrderController@initiateOrder')->name('newOrder');
and from the client app I was posting the request to:
https://my-domain/api/new-order/
So, because of the trailing slash I got a 405. Hope it helps someone

using List Comprehension:
>>> L = [1]*5
>>> [x+1 for x in L]
[2, 2, 2, 2, 2]

which roughly translates to using a for loop:
>>> newL = []
>>> for x in L:
... newL+=[x+1]
...
>>> newL
[2, 2, 2, 2, 2]
or using map:
>>> map(lambda x:x+1, L)

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.
/**
* HTTP request types
*/
public static final int POST_TYPE = 1;
public static final int GET_TYPE = 2;
public static final int PUT_TYPE = 3;
public static final int DELETE_TYPE = 4;
/**
* HTTP request header constants
*/
public static final String CONTENT_TYPE = "Content-Type";
public static final String ACCEPT_ENCODING = "Accept-Encoding";
public static final String CONTENT_ENCODING = "Content-Encoding";
public static final String ENCODING_GZIP = "gzip";
public static final String MIME_FORM_ENCODED = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN = "text/plain";
private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
final Map<String, String> headers, final Map<String, String> params, final int requestType)
throws IOException {
DefaultHttpClient client = HTTPClientFactory.newClient();
client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);
// add user and pass to client credentials if present
if ((user != null) && (pass != null)) {
client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
}
// process headers using request interceptor
final Map<String, String> sendHeaders = new HashMap<String, String>();
if ((headers != null) && (headers.size() > 0)) {
sendHeaders.putAll(headers);
}
if (requestType == HTTPRequestHelper.POST_TYPE || requestType == HTTPRequestHelper.PUT_TYPE ) {
sendHeaders.put(HTTPRequestHelper.CONTENT_TYPE, contentType);
}
// request gzip encoding for response
sendHeaders.put(HTTPRequestHelper.ACCEPT_ENCODING, HTTPRequestHelper.ENCODING_GZIP);
if (sendHeaders.size() > 0) {
client.addRequestInterceptor(new HttpRequestInterceptor() {
public void process(final HttpRequest request, final HttpContext context) throws HttpException,

One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get
public class PageViewModel : IHandle<SomeMessage>
{
...
public async void Handle(SomeMessage message)
{
ShowLoadingAnimation();
// makes UI very laggy, but still not dead
await this.contentLoader.LoadContentAsync();
HideLoadingAnimation();
}
}
public class ContentLoader
{
public async Task LoadContentAsync()
{
var tasks = new List<Task>();
tasks.Add(DoCpuBoundWorkAsync());
tasks.Add(DoIoBoundWorkAsync());
tasks.Add(DoCpuBoundWorkAsync());
tasks.Add(DoSomeOtherWorkAsync());
await Task.WhenAll(tasks).ConfigureAwait(false);
}
}
Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.
I know its an old post, but just to clear this problem... you're just using your classes at the wrong place :D
First of all you could use
svg { fill: red; }
in your main.css
to get it red. This does have effect. You could probably use node selectors as well to get specific paths.
Second thing is, you declared the class to the img
-tag.
<img class='socIcon'....
You actually should declare it inside your SVG. if you have different paths you could define more of course.
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet href="stylesheets/main.css" type="text/css"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 56.69 56.69">
<g>
<path class="myClassForMyPath" d="M28.44......./>
</g>
</svg>
Now you could change the color in your main.css
like
.myClassForMyPath {
fill: yellow;
}
Check out this snippet:

.Filters.Add "All Files", "*.*"
' Show the dialog box. If the .Show method returns True, the

If .Show = True Then
txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox
End If

I think this is what you are asking for.
Method to replace substring in a sentence
using React:
const replace_in_javascript = (oldSubStr, newSubStr, sentence) => {
let newStr = "";
let i = 0;
sentence.split(" ").forEach(obj => {
if (obj.toUpperCase() === oldSubStr.toUpperCase()) {
newStr = i === 0 ? newSubStr : newStr + " " + newSubStr;
i = i + 1;
} else {
newStr = i === 0 ? obj : newStr + " " + obj;
i = i + 1;
}
});
return newStr;
};
I've gotten around this with
mystr = ' '.join(
["Why, hello there",
"wonderful stackoverflow people!"])
in the past. It's not perfect, but it works nicely for very long strings that need to not have line breaks in them.
I tried many solutions but didn't work for me. The below solution works for me.

I had this error crop up today when converting my aaLuminate app to Universal under Xcode 4. This app is based on the utility template and was originally built under Xcode 3.
To save time I copied the iPhone Main and Flipside Views across to appropriate names on the Universal app. I experienced the "Unknown class x in Interface Builder file" error. In my case it was nothing in the XIB files or targets.
I had also copied the aaLuminate-Info.plist file across for other reasons - this had an old key "Main nib file base name" set to MainWindow.
As soon as I deleted this key it fixed the problem!
To prevent unexpected margins and other browser-specific behavior in the future, I'd recommend to include reset.css in your stylesheets.
Be aware that you'll have to set the h[1..6] font size and weight to make headings look like headings again after that, and many other things.
Seems like the accepted answer does not work anymore. I found the correct method from another post: https://stackoverflow.com/a/46811403/6368026
Now you should use:
http://www.youtube.com/embed/videoseries?list=USERID And the USERID is your youtube user id with 'UU' appended.
For example, if your user id is TlQ5niAIDsLdEHpQKQsupg then you should put UUTlQ5niAIDsLdEHpQKQsupg. If you only have the channel id (which you can find in your channel URL) then just replace the first two characters (UC) with UU.
So in the end you would have an URL like this:
http://www.youtube.com/embed/videoseries?list=UUTlQ5niAIDsLdEHpQKQsupg
Simply call jQuery's toggleClass()
on the i
element contained within your a
element(s) to toggle either the plus and minus icons:
...click(function() {
$(this).find('i').toggleClass('fa-minus-circle fa-plus-circle');
});
Note that this assumes that a class of fa-plus-circle
is added to your i
element by default.
I just had the same issue. In my particular case git was removing CR in a http file on check-in, but disregarding the cause, you can follow these steps for debugging the issue: https://technical.fail/posts/2021-01-26-dotnet-framework-throwing-the-server-committed-a-protocol-violation-section-responsestatusline
I would suggest using absolute positioning within the element.
I've created this to help you visualize it a bit.

From the cron man page:
...cron will then examine the modification time on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified
But if you just want to make sure its done anyway,
sudo service cron reload
or
/etc/init.d/cron reload
Relationships in JPA are always unidirectional, unless you associate the parent with the child in both directions. Cascading REMOVE operations from the parent to the child will require a relation from the parent to the child (not just the opposite).
You'll therefore need to do this:
@ManyToOne
relationship to a bi-directional @ManyToOne
, or a unidirectional @OneToMany
. You can then cascade REMOVE operations so that EntityManager.remove
will remove the parent and the children. You can also specify orphanRemoval
as true, to delete any orphaned children when the child entity in the parent collection is set to null, i.e. remove the child when it is not present in any parent's collection.ON DELETE CASCADE
. You'll need to invoke EntityManager.clear()
after calling EntityManager.remove(parent)
as the persistence context needs to be refreshed - the child entities are not supposed to exist in the persistence context after they've been deleted in the database.If all you want to do is enumerate them, use the IEnumerable
.
Beware, though, that changing the original collection being enumerated is a dangerous operation - in this case, you will want to ToList
first. This will create a new list element for each element in memory, enumerating the IEnumerable
and is thus less performant if you only enumerate once - but safer and sometimes the List
methods are handy (for instance in random access).
If your keys are dynamic I would suggest deserializing directly into a DataTable:
class SampleData
{
[JsonProperty(PropertyName = "items")]
public System.Data.DataTable Items { get; set; }
}
public void DerializeTable()
{
const string json = @"{items:["
+ @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
+ @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
+ @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
var table = sampleData.Items;
// write tab delimited table without knowing column names
var line = string.Empty;
foreach (DataColumn column in table.Columns)
line += column.ColumnName + "\t";
Console.WriteLine(line);
foreach (DataRow row in table.Rows)
{
line = string.Empty;
foreach (DataColumn column in table.Columns)
line += row[column] + "\t";
Console.WriteLine(line);
}
// Name Age Job
// AAA 22 PPP
// BBB 25 QQQ
// CCC 38 RRR
}
You can determine the DataTable column names and types dynamically once deserialized.
If you're using IDLE, and the Norwegian keyboard makes Ctrl-[ a problem, you can change the key.
I tried putting in shift-Tab and that worked nicely.
What would you use a ConcurrentList for?
The concept of a Random Access container in a threaded world isn't as useful as it may appear. The statement
if (i < MyConcurrentList.Count)
x = MyConcurrentList[i];
as a whole would still not be thread-safe.
Instead of creating a ConcurrentList, try to build solutions with what's there. The most common classes are the ConcurrentBag and especially the BlockingCollection.
If you like the pipe mode, this is the most clean solution:
tar c some-dir | xz > some-dir.tar.xz
It's not necessary to put the f
option in order to deal with files and then to use -
to specify that the file is the standard input. It's also not necessary to specify the -z
option for xz
, because it's default.
It works with gzip
and bzip2
too:
tar c some-dir | gzip > some-dir.tar.gz
or
tar c some-dir | bzip2 > some-dir.tar.bz2
Decompressing is also quite straightforward:
xzcat tarball.tar.xz | tar x
bzcat tarball.tar.bz2 | tar x
zcat tarball.tar.gz | tar x
If you have only tar
archive, you can use cat
:
cat archive.tar | tar x
If you need to list the files only, use tar t
.
Use ToString()
with this format:
12345.678901.ToString("0.0000"); // outputs 12345.6789
12345.0.ToString("0.0000"); // outputs 12345.0000
Put as much zero as necessary at the end of the format.
You cannot scroll images continuously using the HTML marquee tag - it must have JavaScript added for the continuous scrolling functionality.
There is a JavaScript plugin called crawler.js available on the dynamic drive forum for achieving this functionality. This plugin was created by John Davenport Scheuer and has been modified over time to suit new browsers.
I have also implemented this plugin into my blog to document all the steps to use this plugin. Here is the sample code:
<head>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script src="assets/js/crawler.js" type="text/javascript" ></script>
</head>
<div id="mycrawler2" style="margin-top: -3px; " class="productswesupport">
<img src="assets/images/products/ie.png" />
<img src="assets/images/products/browser.png" />
<img src="assets/images/products/chrome.png" />
<img src="assets/images/products/safari.png" />
</div>
Here is the plugin configration:
marqueeInit({
uniqueid: 'mycrawler2',
style: {
},
inc: 5, //speed - pixel increment for each iteration of this marquee's movement
mouse: 'cursor driven', //mouseover behavior ('pause' 'cursor driven' or false)
moveatleast: 2,
neutral: 150,
savedirection: true,
random: true
});
According to the official documentation, a click on any link in WebView launches an application that handles URLs, which by default is a browser. You need to override the default behavior like this
myWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
I delete that web page that i want to link with master page from web application,add new web page in project then set the master page(Initially I had copied web page from web site into Web application fro coping that aspx page (I was converting website to web application as project))
The following code is a modified example from React.js website.
Original code is available here: https://reactjs.org/#a-simple-component
class Timer extends React.Component {
constructor(props) {
super(props);
this.state = {
seconds: parseInt(props.startTimeInSeconds, 10) || 0
};
}
tick() {
this.setState(state => ({
seconds: state.seconds + 1
}));
}
componentDidMount() {
this.interval = setInterval(() => this.tick(), 1000);
}
componentWillUnmount() {
clearInterval(this.interval);
}
formatTime(secs) {
let hours = Math.floor(secs / 3600);
let minutes = Math.floor(secs / 60) % 60;
let seconds = secs % 60;
return [hours, minutes, seconds]
.map(v => ('' + v).padStart(2, '0'))
.filter((v,i) => v !== '00' || i > 0)
.join(':');
}
render() {
return (
<div>
Timer: {this.formatTime(this.state.seconds)}
</div>
);
}
}
ReactDOM.render(
<Timer startTimeInSeconds="300" />,
document.getElementById('timer-example')
);
Yes, package-lock.json
is intended to be checked into source control. If you're using npm 5+, you may see this notice on the command line: created a lockfile as package-lock.json. You should commit this file.
According to npm help package-lock.json
:
package-lock.json
is automatically generated for any operations where npm modifies either thenode_modules
tree, orpackage.json
. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.This file is intended to be committed into source repositories, and serves various purposes:
Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.
Provide a facility for users to "time-travel" to previous states of
node_modules
without having to commit the directory itself.To facilitate greater visibility of tree changes through readable source control diffs.
And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages.
One key detail about
package-lock.json
is that it cannot be published, and it will be ignored if found in any place other than the toplevel package. It shares a format with npm-shrinkwrap.json, which is essentially the same file, but allows publication. This is not recommended unless deploying a CLI tool or otherwise using the publication process for producing production packages.If both
package-lock.json
andnpm-shrinkwrap.json
are present in the root of a package,package-lock.json
will be completely ignored.

Just multiply the number by 100, round, and divide the resulting number by 100.
Assumption:
list - List<String>
Using Java 8 Streams,
to get first N elements from a list into a list,
List<String> firstNElementsList = list.stream().limit(n).collect(Collectors.toList());
to get first N elements from a list into an Array,
String[] firstNElementsArray = list.stream().limit(n).collect(Collectors.toList()).toArray(new String[n]);
In C++ it is done like this:
#define LOCAL_PI 3.1415926535897932385

double radians = degrees * LOCAL_PI / 180;
return radians;
}
double DirectDistance(double lat1, double lng1, double lat2, double lng2)
{
double earthRadius = 3958.75;
double dLat = ToRadians(lat2-lat1);
double dLng = ToRadians(lng2-lng1);
double a = sin(dLat/2) * sin(dLat/2) +
cos(ToRadians(lat1)) * cos(ToRadians(lat2)) *
sin(dLng/2) * sin(dLng/2);
double c = 2 * atan2(sqrt(a), sqrt(1-a));
double dist = earthRadius * c;
double meterConversion = 1609.00;
return dist * meterConversion;

Seaborn box plot returns a matplotlib axes instance. Unlike pyplot itself, which has a method plt.title()
, the corresponding argument for an axes is ax.set_title()
. Therefore you need to call
sns.boxplot('Day', 'Count', data= gg).set_title('lalala')
A complete example would be:
import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")
sns.boxplot(x=tips["total_bill"]).set_title("LaLaLa")
plt.show()
Of course you could also use the returned axes instance to make it more readable:
ax = sns.boxplot('Day', 'Count', data= gg)
ax.set_title('lalala')
ax.set_ylabel('lololo')
I was trying to restore a production database to a staging database on the same server.
The only thing that worked in my case was restore to a new blank database. This worked great, did not try to overwrite production files (which it would if you just restore production backup file to existing staging database). Then delete old database and rename - the files will keep the new temp name but in my case that is fine.
(Or otherwise delete the staging database first and then you can restore to new database with same name as staging database)
The .sr-only

First the facts, neither is better. As you already mentioned, Tomcat provides a servlet container that supports the Servlet specification (Tomcat 7 supports Servlet 3.0). JBoss AS, a 'complete' application server supports Java EE 6 (including Servlet 3.0) in its current version.
Tomcat is fairly lightweight and in case you need certain Java EE features beyond the Servlet API, you can easily enhance Tomcat by providing the required libraries as part of your application. For example, if you need JPA features you can include Hibernate or OpenEJB and JPA works nearly out of the box.
How to decide whether to use Tomcat or a full stack Java EE
application server:
When starting your project you should have an idea what it requires. If you're in a large enterprise environment JBoss (or any other Java EE server) might be the right choice as it provides built-in support for e.g:
In my opinion Tomcat is a very good fit if it comes to web centric, user facing applications. If backend integration comes into play, a Java EE application server should be (at least) considered. Last but not least, migrating a WAR developed for Tomcat to JBoss should be a 1 day excercise.
Second, you should also take the usage inside your environment into account. In case your organization already runs say 1,000 JBoss instances, you might always go with that regardless of your concrete requirements (consider aspects like cost for operations or upskilling). Of course, this applies vice versa.

Some values are serialized differently between simplejson and json.
Notably, instances of collections.namedtuple
are serialized as arrays by json
but as objects by simplejson
. You can override this behaviour by passing namedtuple_as_object=False
to simplejson.dump
, but by default the behaviours do not match.
>>> import collections, simplejson, json
>>> TupleClass = collections.namedtuple("TupleClass", ("a", "b"))
>>> value = TupleClass(1, 2)
>>> json.dumps(value)
'[1, 2]'
>>> simplejson.dumps(value)
'{"a": 1, "b": 2}'
>>> simplejson.dumps(value, namedtuple_as_object=False)
'[1, 2]'

Basically you cannot but you can bypass the situation.
The correct way to add the foreign key constraint to an existing table is the following command.
db.execSQL("alter table child add column newCol integer REFERENCES parent(parent_Id)");
Then copy the parent_Id data to the newCol and then delete the Parent_Id column. Hence, no need for temporary table.
Close the modal with universal $().hide()
method:
$('#product-options').hide();
This is extension to answers above, if your xml has namespace defined (xmlns
) then you will get a nasty side effect when adding children - xmlns = ""
being added to your new child element.
What you want to do (assuming element you are adding belongs to same namespace as his parent) is to take namespace from parent element parentElement.GetDefaultNamespace()
.
var child = new XElement(parentElement.GetDefaultNamespace()+"Snippet", new XAttribute("Attr1", "42"), new XAttribute("Attr2", "22"));
child.Add(new XAttribute("Attr3", "777"));
parentElement.Add(child);
for parent elements with multiple namespaces you can choose which one to use by changing from parentElement.GetDefaultNamespace()+"Snippet"
to parentElement.GetNamespaceOfPrefix("namespacePrefixThatGoesWithColon")+"Snippet"
e.g
var child = new XElement(parentElement.GetNamespaceOfPrefix("namespacePrefixThatGoesWithColon")+"Snippet", new XAttribute("Attr1", "42"), new XAttribute("Attr2", "22"));

public void hideProgressDialog() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.dismiss();

GETDATE()
returns current date and time.
If last year starts in midnight of current day last year (like in original example) you should use something like:
DECLARE @start datetime
SET @start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) -- getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= @start

When I check my github, I found my github repository's HTTPS url is

I don't know how this happened. The wrong url has been set up by installed Git Shell automatically.
Once I remove the '/' at the end, I can push successfully.
Consider your REST API returns:
{"Intent":{"Command":"search","SubIntent":null}}
Then you can do the following to print it in a nice format:
<pre id="ciResponseText">Output will de displayed here.</pre>
var ciResponseText = document.getElementById('ciResponseText');
var obj = JSON.parse(http.response);
ciResponseText.innerHTML = JSON.stringify(obj, undefined, 2);

As you can see the evolution is insane, about 560 time faster than reported in 2012.
On my machines and servers, following my numerous experiments, basics for loops are the fastest. This is even clearer using nested loops ($i $j $k..)
It is also the most flexible in usage, and has a better readability from my view.
If you do it programmatically in JS it will be like reinventing the wheel. I recommend using a jQuery plugin called jGrowl
I think thats not the reason everybody told above. There is something wrong in your code, maybe miss spelling or mismatching with the database column names. If mysqli query gets no result then it will return false, so that it is not a object - is a wrong idea. Everything works fine. it returns 1 or 0 if query have result or not.
So, my suggestion is check your variable names and table column names or any other misspelling.
In case you'd happen to be using rails and the angular-rails gem then the problem is easily corrected by adding this missing line to application.js (or what ever is applicable in your situation):
//= require angular-resource
How did you install Python, and are you using a virtual environment?
As you specifically mentioned Python 3.6, and you have not marked this as answered I will make a guess that you might have installed it using sudo add-apt-repository ppa:jonathonf/python-3.6, as this is a common way to install Python 3.6 on a Unix OS that doesn't have a native 3.6 package. If this is the case the correct way to install pip is as follows ....
Step 1) Make a Virtual Environment with Python 3.6 ...
python3.6 -m venv env --without-pip
Step 2) Activate your virtual environemnt ...
source env/bin/activate
Step 3) Install pip into your environemnt ...
curl https://bootstrap.pypa.io/get-pip.py | python3

Way late to this post, but I've got something slightly different to say...
>> "Are email addresses case sensitive?"
Well, "It Depends..." (TM)
Some organizations actually think that's a good idea and their email servers enforce case sensitivity.
So, for those crazy places, "Yes, Emails are case sensitive."
Note: Just because a specification says you can do something does not mean it is a good idea to do so.
The principle of KISS suggests that our systems use case insensitive emails.
Whereas the Robustness principle suggests that we accept case sensitive emails.
Solution:
This would mean that if this email already exists: [email protected]
... and another user comes along and wants to use this email: [email protected]
... that our case insensitive searching logic would return a "That email already exists" error message.
Now, you have a decision to make: Is that solution adequate in your case?
If not, you could charge a convenience fee to those clients that demand support for their case sensitive emails and implement custom logic that allows the [email protected] into your system, even if [email protected] already exists.
In which case your email search/validation logic might look like something this pseudocode:
if (user.paidEmailFee) {
// case sensitive email
query = "select * from users where email LIKE ' + user.email + '"
} else {
// case insensitive email
query = "select * from users where email ILIKE ' + user.email + '"
}
This way, you are mostly enforcing case insensitivity but allowing customers to pay for this support if they are using email systems that support such nonsense.
p.s. ILIKE is a PostgreSQL keyword: http://www.postgresql.org/docs/9.2/static/functions-matching.html

edit : you can also double-click, it has the same effect

Un updated answer: in knitr 1.17
you can simply use
![Image Title](path/to/your/image){width=250px}
edit as per comment from @jsb
Note this works only without spaces, e.g. {width=250px} not {width = 250px}
Your format specifier is incorrect. From the printf()
man page on my machine:
0
A zero '0
' character indicating that zero-padding should be used rather than blank-padding. A '-
' overrides a '0
' if both are used;Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);
Precision: An optional period, '
.
', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;
For your case, your format would be %09.3f
:
#include <stdio.h>
int main(int argc, char **argv)
{
printf("%09.3f\n", 4917.24);
return 0;
}
Output:
$ make testapp
cc testapp.c -o testapp
$ ./testapp
04917.240
Note that this answer is conditional on your embedded system having a printf()
implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.
select right(replicate(@padchar, @len) + @str, @len)
var Ihours = Math.floor(TotMin / 60);
var Iminutes = TotMin % 60; var TotalTime = Ihours+":"+Iminutes+':00';
$.ajax({
url: ../..,
cache: false,
type: "POST",
data: JSON.stringify({objRoot: TotalTime}) ,
dataType: 'json',
contentType: "application/json; charset=utf-8",
success: function (response) {
},
error: function (er) {
console.log(er);
}
});
In Github click the "Clone or download" button of the project you want to import --> download the ZIP file and unzip it. In Android Studio Go to File -> New Project -> Import Project and select the newly unzipped folder -> press OK. It will build the Gradle automatically.
Good Luck with your project
Call super.OnMessageReceived()
in the Overriden method. This worked for me!
Finally!
The problem is that flex: 1
sets flex-basis: 0
. Instead, you need
.container .box {
min-width: 200px;
max-width: 400px;
flex-basis: auto; /* default value */
flex-grow: 1;
}

While @nickf's answer works. If you don't care for older browsers, you can use this pure Javascript version. Works in IE9+, and others
var rect = el.getBoundingClientRect();
var position = {
top: rect.top + window.pageYOffset,
left: rect.left + window.pageXOffset
};
Exporting each variable from your variables file. Then importing them with * as in your other file and exporting the as a constant from that file will give you a dynamic object with the named exports from the first file being attributes on the object exported from the second.
Variables.js
export const var1 = 'first';
export const var2 = 'second':
...
export const varN = 'nth';
Other.js
import * as vars from './Variables';
export const Variables = vars;
Third.js
import { Variables } from './Other';
Variables.var2 === 'second'
Possibly browser returns String representation of some integer value? Actually int can't be null. May be you could check for null, if value is not null, then transform String representation to int.
