The button code should be moved to the PlaceholderFragment()
class. There you will call the layout fragment_main.xml
in the onCreateView
method. Like so
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button) view.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onButtonClick((Button) view);
}
});
return view;
}
Apply this style to your TextBox and that's it (inspired from this article):
<Style x:Key="SelectableTextBlockLikeStyle" TargetType="TextBox" BasedOn="{StaticResource {x:Type TextBox}}">
<Setter Property="IsReadOnly" Value="True"/>
<Setter Property="IsTabStop" Value="False"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="Padding" Value="-2,0,0,0"/>
<!-- The Padding -2,0,0,0 is required because the TextBox
seems to have an inherent "Padding" of about 2 pixels.
Without the Padding property,
the text seems to be 2 pixels to the left
compared to a TextBlock
-->

I encountered this issue after swapping server IPs. Database was working fine before that. There was an entry in /etc/my.cnf that I needed to update:
bind-address = xxx.xxx.xxx.xx
It had the old IP address in there.
If you must work with raw arrays and not ArrayList
then Arrays
has what you need. If you look at the source code, these are the absolutely best ways to get a copy of an array. They do have a good bit of defensive programming because the System.arraycopy()
method throws lots of unchecked exceptions if you feed it illogical parameters.
You can use either Arrays.copyOf()
which will copy from the first to Nth
element to the new shorter array.
public static <T> T[] copyOf(T[] original, int newLength)
Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain null. Such indices will exist if and only if the specified length is greater than that of the original array. The resulting array is of exactly the same class as the original array.
2770
2771 public static <T,U> T[] More ...copyOf(U[] original, int newLength, Class<? extends T[]> newType) {
2772 T[] copy = ((Object)newType == (Object)Object[].class)
2773 ? (T[]) new Object[newLength]
2774 : (T[]) Array.newInstance(newType.getComponentType(), newLength);
2775 System.arraycopy(original, 0, copy, 0,
2776 Math.min(original.length, newLength));
2777 return copy;
2778 }
or Arrays.copyOfRange()
will also do the trick:
public static <T> T[] copyOfRange(T[] original, int from, int to)
Copies the specified range of the specified array into a new array. The initial index of the range (from) must lie between zero and original.length, inclusive. The value at original[from] is placed into the initial element of the copy (unless from == original.length or from == to). Values from subsequent elements in the original array are placed into subsequent elements in the copy. The final index of the range (to), which must be greater than or equal to from, may be greater than original.length, in which case null is placed in all elements of the copy whose index is greater than or equal to original.length - from. The length of the returned array will be to - from. The resulting array is of exactly the same class as the original array.
3035 public static <T,U> T[] More ...copyOfRange(U[] original, int from, int to, Class<? extends T[]> newType) {
3036 int newLength = to - from;
3037 if (newLength < 0)
3038 throw new IllegalArgumentException(from + " > " + to);
3039 T[] copy = ((Object)newType == (Object)Object[].class)
3040 ? (T[]) new Object[newLength]
3041 : (T[]) Array.newInstance(newType.getComponentType(), newLength);
3042 System.arraycopy(original, from, copy, 0,
3043 Math.min(original.length - from, newLength));
3044 return copy;
3045 }
As you can see, both of these are just wrapper functions over System.arraycopy
with defensive logic that what you are trying to do is valid.
System.arraycopy
is the absolute fastest way to copy arrays.
I think the problem is that you are using type="text" instead of textarea. What you want is:
<textarea class="span6" rows="3" placeholder="What's up?" required></textarea>
To clarify, a type="text" will always be one row, where-as a textarea can be multiple.
you can read empList
directly in forEach
tag.Try this
<table>
<c:forEach items="${sessionScope.empList}" var="employee">
<tr>
<td>Employee ID: <c:out value="${employee.eid}"/></td>
<td>Employee Pass: <c:out value="${employee.ename}"/></td>
</tr>
</c:forEach>
</table>
var fs = require('fs');
var array = fs.readFileSync('file.txt').toString().split("\n");
for(i in array) {
console.log(array[i]);
}
var fs = require('fs');
fs.readFile('file.txt', function(err, data) {
if(err) throw err;
var array = data.toString().split("\n");
for(i in array) {
console.log(array[i]);
}
});
I got a solution after a long time in tutorials.
I followed the github tutorial on this link -> https://help.github.com/articles/error-permission-denied-publickey and I was able to connect in every step. But when I was trying to git push -u origin master I got this error:
Permission denied (publickey). fatal: Could not read from remote repository.
Please make sure you have the correct access rights
Thats how I`ve fixed it!! Go to the project directory using the Terminal and check it out
$git remote -v
You will get something like this:
origin ssh://[email protected]/yourGithubUserName/yourRepo.git (fetch)
origin ssh://[email protected]/yourGithubUserName/yourRepo.git (push)
If you are using anything different then [email protected], open the config file on git directory by typing the command:
vi .git/config
And configure the line
[remote "origin"]
url = ssh://[email protected]/yourGithubUserName/yourRepo.git
fetch = +refs/heads/*:refs/remotes/origin/
This function should work. this has the photo parameter that holds the base64 string and also path to an existing image directory should you already have an existing image you want to unlink while you save the new one.
public function convertBase64ToImage($photo = null, $path = null) {
if (!empty($photo)) {
$photo = str_replace('data:image/png;base64,', '', $photo);
$photo = str_replace(' ', '+', $photo);
$photo = str_replace('data:image/jpeg;base64,', '', $photo);
$photo = str_replace('data:image/gif;base64,', '', $photo);
$entry = base64_decode($photo);
$image = imagecreatefromstring($entry);
$fileName = time() . ".jpeg";
$directory = "uploads/customer/" . $fileName;
header('Content-type:image/jpeg');
if (!empty($path)) {
if (file_exists($path)) {
unlink($path);
}
}
$saveImage = imagejpeg($image, $directory);
imagedestroy($image);
if ($saveImage) {
return $fileName;
} else {
return false; // image not saved
}
}
}
No, React doesn't render everything when the state changes.
Whenever a component is dirty (its state changed), that component and its children are re-rendered. This, to some extent, is to re-render as little as possible. The only time when render isn't called is when some branch is moved to another root, where theoretically we don't need to re-render anything. In your example, TimeInChild
is a child component of Main
, so it also gets re-rendered when the state of Main
changes.
React doesn't compare state data. When setState
is called, it marks the component as dirty (which means it needs to be re-rendered). The important thing to note is that although render
method of the component is called, the real DOM is only updated if the output is different from the current DOM tree (a.k.a diffing between the Virtual DOM tree and document's DOM tree). In your example, even though the state
data hasn't changed, the time of last change did, making Virtual DOM different from the document's DOM, hence why the HTML is updated.
The enctype attribute specifies how the form-data should be encoded when submitting it to the server.
The enctype attribute can be used only if method="post".
No characters are encoded. This value is required when you are using forms that have a file upload control

Figured it out by testing all the stuff by myself. Couldn't find any topics about it tho, so I'll just leave the solution here. This might not be the only or even the best solution, but it works for my purposes (within getch's limits) and is better than nothing.
Note: proper keyDown()
which would recognize all the keys and actual key presses, is still valued.
Solution: using ord()
-function to first turn the getch()
into an integer (I guess they're virtual key codes, but not too sure) works fine, and then comparing the result to the actual number representing the wanted key. Also, if I needed to, I could add an extra chr()
around the number returned so that it would convert it to a character. However, I'm using mostly down arrow, esc, etc. so converting those to a character would be stupid. Here's the final code:
from msvcrt import getch
while True:
key = ord(getch())
if key == 27: #ESC
break
elif key == 13: #Enter
select()
elif key == 224: #Special keys (arrows, f keys, ins, del, etc.)
key = ord(getch())
if key == 80: #Down arrow
moveDown()
elif key == 72: #Up arrow
moveUp()
Also if someone else needs to, you can easily find out the keycodes from google, or by using python and just pressing the key:
from msvcrt import getch
while True:
print(ord(getch()))
Just wanted to contribute a solution that I used for my app.
It is also based on the OnScrollListener
interface, but I found it to have a much better scrolling performance on low-end devices, since none of the visible/total count calculations are carried out during the scroll operations.
ListFragment
or ListActivity
implement OnScrollListener
Add the following methods to that class:
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
//leave this empty
}
@Override
public void onScrollStateChanged(AbsListView listView, int scrollState) {
if (scrollState == SCROLL_STATE_IDLE) {
if (listView.getLastVisiblePosition() >= listView.getCount() - 1 - threshold) {
currentPage++;
//load more list items:
loadElements(currentPage);
}
}
}
where currentPage
is the page of your datasource that should be added to your list, and threshold
is the number of list items (counted from the end) that should, if visible, trigger the loading process. If you set threshold
to 0
, for instance, the user has to scroll to the very end of the list in order to load more items.
(optional) As you can see, the "load-more check" is only called when the user stops scrolling. To improve usability, you may inflate and add a loading indicator to the end of the list via listView.addFooterView(yourFooterView)
. One example for such a footer view:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/footer_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp" >
<ProgressBar
android:id="@+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_gravity="center_vertical" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="@+id/progressBar1"
android:padding="5dp"
android:text="@string/loading_text" />
</RelativeLayout>
(optional) Finally, remove that loading indicator by calling listView.removeFooterView(yourFooterView)
if there are no more items or pages.
A minor but notable advantage of a list over a tuple is that lists tend to be slightly more portable. Standard tools are less likely to support tuples. JSON, for example, does not have a tuple type. YAML does, but its syntax is ugly compared to its list syntax, which is quite nice.
In those cases, you may wish to use a tuple internally then convert to list as part of an export process. Alternately, you might want to use lists everywhere for consistency.
Putting this information here for future readers' benefit.
401 (Unauthorized) response header -> Request authentication header
Here are several WWW-Authenticate
response headers. (The full list is at IANA: HTTP Authentication Schemes.)
WWW-Authenticate: Basic
-> Authorization: Basic + token - Use for basic authentication WWW-Authenticate: NTLM
-> Authorization: NTLM + token (2 challenges)WWW-Authenticate: Negotiate
-> Authorization: Negotiate + token - used for Kerberos authentication
Negotiate
: This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).You can set the Authorization: Basic
header only when you also have the WWW-Authenticate: Basic
header on your 401 challenge.
But since you have WWW-Authenticate: Negotiate
this should be the case for Kerberos based authentication.
If you want to open it for a range and for a protocol
ufw allow 11200:11299/tcp

For multiple permission you can use this code :
final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
private void insertDummyContactWrapper() {
List<String> permissionsNeeded = new ArrayList<String>();
final List<String> permissionsList = new ArrayList<String>();
if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
permissionsNeeded.add("GPS");
if (!addPermission(permissionsList, Manifest.permission.READ_CONTACTS))
permissionsNeeded.add("Read Contacts");
if (!addPermission(permissionsList, Manifest.permission.WRITE_CONTACTS))
permissionsNeeded.add("Write Contacts");
if (permissionsList.size() > 0) {
if (permissionsNeeded.size() > 0) {
// Need Rationale
String message = "You need to grant access to " + permissionsNeeded.get(0);
for (int i = 1; i < permissionsNeeded.size(); i++)
message = message + ", " + permissionsNeeded.get(i);
showMessageOKCancel(message,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
}
});
return;
}
requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
return;
}
insertDummyContact();
}
private boolean addPermission(List<String> permissionsList, String permission) {
if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
permissionsList.add(permission);
// Check for Rationale Option
if (!shouldShowRequestPermissionRationale(permission))
return false;
}
return true;
}
Date long getTime()

represented by this Date object.
//test if date1 is before date2
if(date1.getTime() < date2.getTime()) {

}
Another handy alternative is to use screen command to run the main program and direct the stderr and stdout to a file, then use tail -f to view the file as it is being written to.
You could also open another session if you don't want to use screen.
$.parseJSON
Note: this answer provides a jQuery extension that adds automatic ISO and .net date format support.
Since you're using Asp.net MVC I suspect you're using jQuery on the client side. I suggest you read this blog post that has code how to use $.parseJSON
to automatically convert dates for you.
Code supports Asp.net formatted dates like the ones you mentioned as well as ISO formatted dates. All dates will be automatically formatted for you by using $.parseJSON()
.
How about this:
>>> with open('a', 'r') as fin: lines = fin.readlines()
>>> for i, line in enumerate(lines):
if i > 30: break
if i == 26: dox()
if i == 30: doy()
The given answers do the trick for outer shadow i.e. around the widget. I wanted a shadow on the widget which is inside the boundaries and according to the github issue there is no inset attribute in ShadowBox yet. My workaround was to add a layer of widget with a gradient using the stack widget so that it looks like the widget itself has the shadows. You must use the mediaQuery for dimensions otherwise the layout will be messed up on different devices. Here's a sample of code for better understanding:
Stack(
children: <Widget>[
Container(
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.cover,
image: AssetImage("assets/sampleFaces/makeup.jpeg"),
// fit: BoxFit.cover,
),
),
height: 350.0,
),
Container(
decoration: BoxDecoration(
gradient: LinearGradient(
begin: FractionalOffset.topCenter,
end: FractionalOffset.bottomCenter,
colors: [
Colors.black.withOpacity(0.0),
Colors.black54,
],
stops: [0.95, 5.0],
),
),
)
],
),

I am not sure what you are trying to accomplish, but you may want to consider that passing a class may not be what you really need to be doing. In many cases, dealing with Class like this is easily encapsulated within a factory pattern of some type and the use of that is done through an interface. here's one of dozens of articles on that pattern: http://today.java.net/pub/a/today/2005/03/09/factory.html
using a class within a factory can be accomplished in a variety of ways, most notably by having a config file that contains the name of the class that implements the required interface. Then the factory can find that class from within the class path and construct it as an object of the specified interface.

According to this article, you want a mod_rewrite (placed in an .htaccess
file) rule that looks something like this:
RewriteEngine on
RewriteRule ^/news/([0-9]+)\.html /news.php?news_id=$1
And this maps requests from
/news.php?news_id=63
to
/news/63.html
Another possibility is doing it with forcetype
, which forces anything down a particular path to use php to eval the content. So, in your .htaccess
file, put the following:
<Files news>
ForceType application/x-httpd-php
</Files>
And then the index.php can take action based on the $_SERVER['PATH_INFO']
variable:
<?php
echo $_SERVER['PATH_INFO'];
// outputs '/63.html'
?>
For anyone having this error after spliting modules check your routes, the following happened to me:

It could be related to log4j.
Do you have log4j.jar file in the websphere java classpath (as defined in the startup file) as well as the application classpath ?
If you do make sure that the log4j.jar file is in the java classpath and that it is NOT in the web-inf/lib directory of your webapp.
It can also be related with the ant version (may be not your case, but I do put it here for reference):
You have a .class file in your class path (i.e. not a directory or a .jar file). Starting with ant 1.6, ant will open the files in the classpath checking for manifest entries. This attempted opening will fail with the error "java.util.zip.ZipException"
The problem does not exist with ant 1.5 as it does not try to open the files. - so make sure that your classpath's do not contain .class files.
On a side note, did you consider having separate jars ?
You could in the manifest of your main jar, refer to the other jars with this attribute:
Class-Path: one.jar two.jar three.jar
Then, place all of your jars in the same folder.
Again, may be not valid for your case, but still there for reference.

Before that, I tried SOAPUI and had some issues with the free version. Plus the cases are in xml files which hard to extend and reuse, simply I don't like
See if your script is running GPU in Task manager. If not, suspect your CUDA version is right one for the tensorflow version you are using, as the other answers suggested already.
Additionally, a proper CUDA DNN library for the CUDA version is required to run GPU with tensorflow. Download/extract it from here and put the DLL (e.g., cudnn64_7.dll) into CUDA bin folder (e.g., C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin).
Depending on your use case, instead of using a case statement, you can use the union of multiple select statements, one for each condition.
My goal when I found this question was to select multiple columns conditionally. I didn't necessarily need the case statement, so this is what I did.
For example:
SELECT
a1,
a2,
a3,
...
WHERE <condition 1>
AND (<other conditions>)
UNION
SELECT
b1,
b2,
b3,
...
WHERE <condition 2>
AND (<other conditions>)
UNION
SELECT
...
-- and so on
Be sure that exactly one condition evaluates to true at a time.
I'm using Postgresql, and the query planner was smart enough to not run a select statement at all if the condition in the where clause evaluated to false (i.e. only one of the select statement actually runs), so this was also performant for me.
try following solution
HTML:
<div id="variant">
<label><input type="radio" name="toggle" class="radio" value="19,99€"><span>A</span></label>
<label><input type="radio" name="toggle" class="radio" value="<<<"><span>B</span></label>
<label><input type="radio" name="toggle" class="radio" value="xxx"><span>C</span></label>
<p id="price"></p>
JS:
$(document).ready(function () {
$('.radio').click(function () {
document.getElementById('price').innerHTML = $(this).val();
});
});
You could wrap the textbox and button in an ASP:Panel, and set the DefaultButton property of the Panel to the Id of your Submit button.
<asp:Panel ID="Panel1" runat="server" DefaultButton="SubmitButton">
<asp:TextBox ID="TextBox1" runat="server" />
<asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" />
</asp:Panel>
Now anytime the focus is within the Panel, the 'SubmitButton_Click' event will fire when enter is pressed.
Flutter now contains a Visibility Widget that you should use to show/hide widgets. The widget can also be used to switch between 2 widgets by changing the replacement.
This widget can achieve any of the states visible, invisible, gone and a lot more.
Visibility(
visible: true //Default is true,
child: Text('Ndini uya uya'),
//maintainSize: bool. When true this is equivalent to invisible;
//replacement: Widget. Defaults to Sizedbox.shrink, 0x0
),
Here is a possible solution:
From your first script, call your second script with the following line:
wscript.exe invis.vbs run.bat %*
Actually, you are calling a vbs script with:
%*
)Then, invis.vbs will call your script with the Windows Script Host Run() method, which takes:
Here is invis.vbs:
set args = WScript.Arguments
num = args.Count
if num = 0 then
WScript.Echo "Usage: [CScript | WScript] invis.vbs aScript.bat <some script arguments>"
WScript.Quit 1
end if
sargs = ""
if num > 1 then
sargs = " "
for k = 1 to num - 1
anArg = args.Item(k)
sargs = sargs & anArg & " "
next
end if
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run """" & WScript.Arguments(0) & """" & sargs, 0, False
Actually what made this so confusing is that the Beanstalk people stand behind their very non-standard use of Staging (it comes before development in their diagram, and it's not a mistake!
I put the following at the end of my .vimrc file:
noremap H ddkkp
noremap N ddp
So now 'H' and 'N' move current line up and down respectively.
For me this one worked
success: function(data){
alert("SUCCCESS");
$.each(data,function(index,itemData){
console.log(JSON.stringify(itemData));
$("#fromDay").append( new Option(itemData.lookupLabel,itemData.id) )
});
}
It's destroy
and destroy_all
methods, like
user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)
Alternatively you can use delete
and delete_all
which won't enforce :before_destroy
and :after_destroy
callbacks or any dependent association options.
User.delete_all(condition: 'value')
will allow you to delete records without a primary key
Note: from @hammady's comment, user.destroy
won't work if User model has no primary key.
Note 2: From @pavel-chuchuva's comment, destroy_all
with conditions and delete_all
with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html

SPARK DEFINITIONS:
It may be useful to provide some simple definitions for the Spark nomenclature:
Node: A server
Worker Node: A server that is part of the cluster and are available to run Spark jobs
Master Node: The server that coordinates the Worker nodes.
Executor: A sort of virtual machine inside a node. One Node can have multiple Executors.
Driver Node: The Node that initiates the Spark session. Typically, this will be the server where sparklyr is located.
Driver (Executor): The Driver Node will also show up in the Executor list.

Select project/file that contains bad change, and from pop-up menu choose:
Team -> Show History
Revisions related to that project/file will be shown in History tab.
Find revision where "bad changes" were committed and from pop-up menu choose:
Revert Changes from Revision X
This will merge changes in file(s) modified within bad revision, with revision prior to bad revision.
There are two scenarios from here:
If you committed no changes for that file (bad revision is last revision for that file), it will simply remove changes made in bad revision. Those changes are merged to your working copy so you have to commit them.
If you committed some changes for that file (bad revision is not last revision for that file), you will have to manually resolve conflict. Let say that you have file readme.txt with, and bad revision number is 33. Also, you've made another commit for that file in revision 34. After you choose Revert Changes from Revision 33 you will have following in your working copy:
readme.txt.merge-left.r33 - bad revision
readme.txt.merge-right.r32 - before bad revision
readme.txt.working - working copy version (same as in r34 if you don't have any uncommitted changes)
Original readme.txt will be marked conflicted, and will contain merged version (where changes from bad revision are removed) with some markers (<<<<<<< .working etc). If you just want to remove changes from bad revision and keep changes made after that, then all you have to do is remove markers. Otherwise, you can copy contents from one of 3 files mentioned above to original file. Whatever you choose, when you are done, mark conflict resolved by
Team - Mark Resolved
Temporary files will be removed and your file will be marked changed. As in 1, you have to commit changes.
Note that this does not remove revision from revision history in svn repository. You simply made new revision where changes from bad revision are removed.

You can use mutate_if
(dplyr
):
For example, coerce integer
in factor
:
mydata=structure(list(a = 1:10, b = 1:10, c = c("a", "a", "b", "b",
"c", "c", "c", "c", "c", "c")), row.names = c(NA, -10L), class = c("tbl_df",
"tbl", "data.frame"))
# A tibble: 10 x 3
a b c
<int> <int> <chr>
1 1 1 a
2 2 2 a
3 3 3 b
4 4 4 b
5 5 5 c
6 6 6 c
7 7 7 c
8 8 8 c
9 9 9 c
10 10 10 c
Use the function:
library(dplyr)
mydata%>%
mutate_if(is.integer,as.factor)
# A tibble: 10 x 3
a b c
<fct> <fct> <chr>
1 1 1 a
2 2 2 a
3 3 3 b
4 4 4 b
5 5 5 c
6 6 6 c
7 7 7 c
8 8 8 c
9 9 9 c
10 10 10 c
findIndex
was added in 1.8:
index = _.findIndex(tv, function(voteItem) { return voteItem.id == voteID })
See: http://underscorejs.org/#findIndex
Alternatively, this also works, if you don't mind making another temporary list:
index = _.indexOf(_.pluck(tv, 'id'), voteId);
If your vector is not ordered, use the approach MSN suggested:
if(std::find(vector.begin(), vector.end(), item)!=vector.end()){
// Found the item
}
If your vector is ordered, use binary_search method Brian Neal suggested:
if(binary_search(vector.begin(), vector.end(), item)){
// Found the item
}
binary search yields O(log n) worst-case performance, which is way more efficient than the first approach. In order to use binary search, you may use qsort to sort the vector first to guarantee it is ordered.
Note that if you care about speed and do not need to worry about singularities, solve()
should be preferred to ginv()
because it is much faster, as you can check:
require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)
t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0
t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1
Install Flysystem:
composer require league/flysystem-sftp
Then:
use League\Flysystem\Filesystem;
use League\Flysystem\Sftp\SftpAdapter;
$filesystem = new Filesystem(new SftpAdapter([
'host' => 'example.com',
'port' => 22,
'username' => 'username',
'password' => 'password',
'privateKey' => 'path/to/or/contents/of/privatekey',
'root' => '/path/to/root',
'timeout' => 10,
]));
$filesystem->listFiles($path); // get file lists
$filesystem->read($path_to_file); // grab file
$filesystem->put($path); // upload file
....
Read:
If your code can sensibly be written as a case statement, this is pretty decent:
case mybool
when TrueClass, FalseClass
puts "It's a bool!"
else
puts "It's something else!"
end

Quick steps:
1) Open up the Developer Tools dashboard by going to the Chrome Menu -> Tools -> Developer Tools
2) Click on the settings icon on the right hand side (it's a cog!)
3) Check the box "Disable cache (when DevTools is open)"
4) Now, while the dashboard is up, just hit refresh and JS won't be cached!
Interesting, I didn't have any references to stdole in my project, but I had a user still receiving the error. I had to add the reference, then change the setting to include. Hopefully that will work.
You can use the following code. It is similar to existing functions except that you can force special character count:
function random_string() {
// 8 characters: 7 lower-case alphabets and 1 digit
$character_sets = [
["count" => 7, "characters" => "abcdefghijklmnopqrstuvwxyz"],
["count" => 1, "characters" => "0123456789"]
];
$temp_array = array();
foreach ($character_sets as $character_set) {
for ($i = 0; $i < $character_set["count"]; $i++) {
$random = random_int(0, strlen($character_set["characters"]) - 1);
$temp_array[] = $character_set["characters"][$random];
}
}
shuffle($temp_array);
return implode("", $temp_array);
}
The answer is opinion. I worked in a lot of projects and being testmanager and issuemanager and all different roles and the descriptions in various books differ so here is my variation:
functional-testing: take the business requirements and test all of it good and thorougly from a functional viewpoint.
acceptance-testing: the "paying" customer does the testing he likes to do so that he can accept the product delivered. It depends on the customer but usually the tests are not as thorough as the functional-testing especially if it is an in-house project because the stakeholders review and trust the test results done in earlier test phases.
As I said this is my viewpoint and experience. The functional-testing is systematic and the acceptance-testing is rather the business department testing the thing.
I can think of a cheeky way to do it, I don't think this will be the best option but it will work.
Create the header as a separate table then place the other in a div and set a max size, then allow the scroll to come in by using overflow

You have to escape each \
to be \\
:
var ttt = "aa ///\\\\\\";
Updated: I think this question is not about the escape character in string at all. The asker doesn't seem to explain the problem correctly.
because you had to show a message to user that user can't give a name which has (\) character.
I think the scenario is like:
var user_input_name = document.getElementById('the_name').value;
Then the asker wants to check if user_input_name
contains any [\
]. If so, then alert the user.
If user enters [aa ///\
] in HTML input box, then if you alert(user_input_name)
, you will see [aaa ///\
]. You don't need to escape, i.e. replace [\
] to be [\\
] in JavaScript code. When you do escaping, that is because you are trying to make of a string which contain special characters in JavaScript source code. If you don't do it, it won't be parsed correct. Since you already get a string, you don't need to pass it into an escaping function. If you do so, I am guessing you are generating another JavaScript code from a JavaScript code, but it's not the case here.
I am guessing asker wants to simulate the input, so we can understand the problem. Unfortunately, asker doesn't understand JavaScript well. Therefore, a syntax error code being supplied to us:
var ttt = "aa ///\";
Hence, we assume the asker having problem with escaping.
If you want to simulate, you code must be valid at first place.
var ttt = "aa ///\\"; // <- This is correct
// var ttt = "aa ///\"; // <- This is not.
alert(ttt); // You will see [aa ///\] in dialog, which is what you expect, right?
Now, you only need to do is
var user_input_name = document.getElementById('the_name').value;
if (user_input_name.indexOf("\\") >= 0) { // There is a [\] in the string
alert("\\ is not allowed to be used!"); // User reads [\ is not allowed to be used]
do_something_else();
}
Edit: I used []
to quote text to be shown, so it would be less confused than using ""
.
In my case, jQuery one had some side effects (in IE8) and I ended up using the following :
$(document).ready(function(){
$("*").dblclick(function(e){
e.preventDefault();
});
});
which works very nicely and looks simpler. Found it there: http://www.jquerybyexample.net/2013/01/disable-mouse-double-click-using-javascript-or-jquery.html
You need to be careful with inheritance:
>>> class Foo:
def __eq__(self, other):
if isinstance(other, self.__class__):
return self.__dict__ == other.__dict__
else:
return False
>>> class Bar(Foo):pass
>>> b = Bar()
>>> f = Foo()
>>> f == b
True
>>> b == f
False
Check types more strictly, like this:
def __eq__(self, other):
if type(other) is type(self):
return self.__dict__ == other.__dict__
return False
Besides that, your approach will work fine, that's what special methods are there for.
try:
a # does a exist in the current namespace
except NameError:
a = 10 # nope
Consider using a package to automatically generate inline styles from your css files. A good one is Grunt Critical or Critical css for Laravel.
this problem can be solved by installing the latest libstdc++.
$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update
$ sudo apt-get install libstdc++6-7-dbg
The problem is that your regex is a string, but html
is bytes:
>>> type(html)
<class 'bytes'>
Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.
You can either decode
the bytes to a string:
html = html.decode('ISO-8859-1') # encoding may vary!
title = re.findall(pattern, html) # no more error
Or use a bytes regex:
regex = rb'<title>(,+?)</title>'
# ^
In this particular context, you can get the encoding from the response headers:
with urllib.request.urlopen(url) as response:
encoding = response.info().get_param('charset', 'utf8')
html = response.read().decode(encoding)
See the urlopen
documentation for more details.
You might want to consider using some algorithms instead:
// read in the data:
std::copy(std::istream_iterator<double>(input),
std::istream_iterator<double>(),
std::back_inserter(v));
sum = std::accumulate(v.begin(), v.end(), 0);
average = sum / v.size();
You can modify the values with std::transform
, though until we get lambda expressions (C++0x) it may be more trouble than it's worth:
class difference {
double base;
public:
difference(double b) : base(b) {}
double operator()(double v) { return v-base; }
};
std::transform(v.begin(), v.end(), v.begin(), difference(average));
referring only to the case where null is not considered an exceptional behavior i am definitely for the try method, it is clear, no need to "read the book" or "look before you leap" as was said here
so basically:
bool TryFindObject(RequestParam request, out ResponseParam response)
and this means that the user's code will also be clear
...
if(TryFindObject(request, out response)
{
handleSuccess(response)
}
else
{
handleFailure()
}
...
Something like this is what I use all the time. No need for any base64 decoding.
<html>
<head>
<script>
window.onload = function(event) {
document.getElementById('fileInput').addEventListener('change', handleFileSelect, false);
}
function handleFileSelect(event) {
var fileReader = new FileReader();
fileReader.onload = function(event) {
$('#accessKeyField').val(event.target.result);
}
var file = event.target.files[0];
fileReader.readAsText(file);
document.getElementById('fileInput').value = null;
}
</script>
</head>
<body>
<input type="file" id="fileInput" style="height: 20px; width: 100px;">

The solutions posted here did not work well for me, so I did a mixture of the ones of this question and the following question: Is it possible to create multi-level ordered list in HTML?
/* Numbered lists like 1, 1.1, 2.2.1... */
ol li {display:block;} /* hide original list counter */
ol > li:first-child {counter-reset: item;} /* reset counter */
ol > li {counter-increment: item; position: relative;} /* increment counter */
ol > li:before {content:counters(item, ".") ". "; position: absolute; margin-right: 100%; right: 10px;} /* print counter */
Result:

My guess is that you've got something in method1
which wraps one exception in another, and uses the toString()
of the nested exception as the message of the wrapper. I suggest you take a copy of your project, and remove as much as you can while keeping the problem, until you've got a short but complete program which demonstrates it - at which point either it'll be clear what's going on, or we'll be in a better position to help fix it.
Here's a short but complete program which demonstrates RuntimeException.getMessage()
behaving correctly:
public class Test {
public static void main(String[] args) {
try {
failingMethod();
} catch (Exception e) {
System.out.println("Error: " + e.getMessage());
}
}
private static void failingMethod() {
throw new RuntimeException("Just the message");
}
}
Output:
Error: Just the message
In contrast to traditional html comments like this:
<!-- not so secret secrets -->
Django template comments are not rendered in the final html. So you can feel free to stuff implementation details in there like so:
Multi-line:
{% comment %}
The other half of the flexbox is defined
in a different file `sidebar.html`
as <div id="sidebar-main">.
{% endcomment %}
Single line:
{# jquery latest #}
{#
beware, this won't be commented out...
actually renders as regular body text on the page
#}
I find single line comments especially helpful for <a href="{% url 'view_name' %}"
views that have not been created yet.
Oh, I just found that command on PostgreSQL forum:
SELECT * FROM pg_stat_activity;
Of course. The whole idea of abstract classes is that they can contain some behaviour or data which you require all sub-classes to contain. Think of the simple example of WheeledVehicle - it should have a numWheels member variable. You want all sub classes to have this variable. Remember that abstract classes are a very useful feature when developing APIs, as they can ensure that people who extend your API won't break it.
I put the following in my .gvimrc file, which searches up the tree from any point for a tags file when gvim starts:
function SetTags()
let curdir = getcwd()
while !filereadable("tags") && getcwd() != "/"
cd ..
endwhile
if filereadable("tags")
execute "set tags=" . getcwd() . "/tags"
endif
execute "cd " . curdir
endfunction
call SetTags()
I then periodically regenerate a tags file at the top of my source tree with a script that looks like:
#!/bin/bash
find . -regex ".*\.\(c\|h\|hpp\|cc\|cpp\)" -print | ctags --totals --recurse --extra="+qf" --fields="+i" -L -

// "body": "WhatsApp API on chat-api.com works good"

console.log(res.status);
// var jsonData = res.body;
// var jsonParsed = JSON.parse(JSON.stringify(jsonData));

response.json("error")
})
Technically, const
is not part of the ECMAScript specification. Also, using the "CommonJS Module" pattern you've noted, you can change the value of that "constant" since it's now just an object property. (not sure if that'll cascade any changes to other scripts that require the same module, but it's possible)
To get a real constant that you can also share, check out Object.create
, Object.defineProperty
, and Object.defineProperties
. If you set writable: false
, then the value in your "constant" cannot be modified. :)
It's a little verbose, (but even that can be changed with a little JS) but you should only need to do it once for your module of constants. Using these methods, any attribute that you leave out defaults to false
. (as opposed to defining properties via assignment, which defaults all the attributes to true
)
So, hypothetically, you could just set value
and enumerable
, leaving out writable
and configurable
since they'll default to false
, I've just included them for clarity.
Update - I've create a new module (node-constants) with helper functions for this very use-case.
Object.defineProperty(exports, "PI", {
value: 3.14,
enumerable: true,
writable: false,
configurable: false
});
function define(name, value) {
Object.defineProperty(exports, name, {
value: value,
enumerable: true
});
}
define("PI", 3.14);
var constants = require("./constants");
console.log(constants.PI); // 3.14
constants.PI = 5;
console.log(constants.PI); // still 3.14

My problem was, that I had custom Textwatcher
, so I didn't want to add OnKeyListener
to an EditText
as well as I didn't want to create custom EditText
. I wanted to detect if backspace was pressed in my afterTextChanged
method, so I shouldn't trigger my event.
This is how I solved this. Hope it would be helpful for someone.
public class CustomTextWatcher extends AfterTextChangedTextWatcher {
private boolean backspacePressed;
@Override
public void afterTextChanged(Editable s) {
if (!backspacePressed) {
triggerYourEvent();
}
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
super.onTextChanged(s, start, before, count);
backspacePressed = count == 0; //if count == 0, backspace is pressed
}
}

Make sure you have the correct database selected. You may have the master database selected if you are trying to run it in a new query window.
In version 7.1.2 pip downloads the wheel of a package (if available) with the following:
pip install package -d /path/to/downloaded/file
The following downloads a source distribution:
pip install package -d /path/to/downloaded/file --no-binary :all:
These download the dependencies as well, if pip is aware of them (e.g., if pip show package
lists them).
Update
As noted by Anton Khodak, pip download
command is preferred since version 8. In the above examples this means that /path/to/downloaded/file
needs to be given with option -d
, so replacing install
with download
works.
Update
Inspired by Daniel's code above and the fact that this is WAY! more interesting to me now then the actual work I have to do, i created a hopefully full-proof function to find the first blank row in a sheet.

'returns the row # of the row after the last used row
'Or the first row with no data in it
Dim rngSearch As Range, cel As Range
With ws
Set rngSearch = .UsedRange.Columns(1).Find("") '-> does blank exist in the first column of usedRange
If Not rngSearch Is Nothing Then

'-> yeap!, then no blank rows!
MsgBox "Whoa! All rows in sheet are used. No blank rows exist!"
Else
'-> okay, blank row exists

Original Answer
To find the first blank in a sheet, replace this part of your code:
Cells(1, 1).Select
For Each Cell In ws.UsedRange.Cells
If Cell.Value = "" Then Cell = Num
MsgBox "Checking cell " & Cell & " for value."
Next
With this code:
With ws
Dim rngBlanks As Range, cel As Range
Set rngBlanks = Intersect(.UsedRange, .Columns(1)).Find("")
If Not rngBlanks Is Nothing Then '-> make sure blank cell exists in first column of usedrange
'-> find all blank rows in column A within the used range
Set rngBlanks = Intersect(.UsedRange, .Columns(1)).SpecialCells(xlCellTypeBlanks)
For Each cel In rngBlanks '-> loop through blanks in column A
'-> do a countA on the entire row, if it's 0, there is nothing in the row
If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then
num = cel.Row
Exit For
End If
Next
Else
num = usedRange.SpecialCells(xlCellTypeLastCell).Offset(1).Row
End If
End With
If you are getting an error like the one below:
OperationalError: FATAL: no pg_hba.conf entry for host "your ipv6",
user "username", database "postgres", SSL off
then add an entry like the following, with your mac address.
host all all [your ipv6]/128 md5
Here is simplest way how to change navbar color after window scroll:
Add follow JS to head:
$(function () {
$(document).scroll(function () {
var $nav = $(".navbar-fixed-top");
$nav.toggleClass('scrolled', $(this).scrollTop() > $nav.height());
});
});
and this CSS code
.navbar-fixed-top.scrolled {
background-color: #fff !important;
transition: background-color 200ms linear;
}
Background color of fixed navbar will be change to white when scroll exceeds height of navbar.
See follow JsFiddle
Keep it Simple and use Java 8:-
Map<String, AccountGroupMappingModel> mapAccountGroup=CustomerDAO.getAccountGroupMapping();
Map<String, AccountGroupMappingModel> mapH2ToBydAccountGroups =
mapAccountGroup.entrySet().stream()
.collect(Collectors.toMap(e->e.getValue().getH2AccountGroup(),
e ->e.getValue())
);
You can use arrows
:
arrows(x,y-sd,x,y+sd, code=3, length=0.02, angle = 90)
For example :
<div style="height:100px; width:100px; background:#000000"></div>
_x000D_
here.
you give css to div of height and width having 100px and background as black.
PS : try to avoid inline-css you can make external CSS and import in your html file.
you can refer here for CSS
hope this helps.
I tried a lot ways and it's not working tho, not sure is it because i'm using shared transition from fragment to activity containing the edit text.
Btw my edittext is also wrapped in LinearLayout.
I added a slight delay to request focus and below code worked for me: (Kotlin)
et_search.postDelayed({
editText.requestFocus()
showKeyboard()
},400) //only 400 is working fine, even 300 / 350, the cursor is not showing
showKeyboard()
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0)
This is the easiest way to pull the p-values:
coef(summary(modelname))[, "Pr(>|t|)"]
Foole's code worked perfectly for me, but in .NET 4.0, don't forget to check if Proxy is NULL, which means no proxy configured (outside corporate environment)
So here's the code that solved my problem with our corporate proxy
WebClient web = new WebClient();
if (web.Proxy != null)
web.Proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
MySQL says:
All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.
When do I use it ?
Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED
data type.
A common mistake is to use a primary key that is an auto-increment INT
starting at zero, yet the type is SIGNED
, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.
In javascript you can do:
var element = document.getElementById("myid");
element.style.position = "fixed";
element.style.top = "0%";
Thats because DataGridView looks for properties of containing objects. For string there is just one property - length. So, you need a wrapper for a string like this
public class StringValue
{
public StringValue(string s)
{
_value = s;
}
public string Value { get { return _value; } set { _value = value; } }
string _value;
}
Then bind List<StringValue>
object to your grid. It works
public static IEnumerable<string> GetData()
{
yield return "1";
yield return "2";
yield return "3";
}
IEnumerable<string> m_oEnum = GetData();
In the DOM, a tr
element is (implicitly or explicitly) a child of tbody
, thead
, or tfoot
, not a child of table
(hence the 0 you got). So a general answer is:
var count = $('#gvPerformanceResult > * > tr').length;
This includes the rows of the table but excludes rows of any inner table.
It is bad form to use this
in lock statements because it is generally out of your control who else might be locking on that object.
In order to properly plan parallel operations, special care should be taken to consider possible deadlock situations, and having an unknown number of lock entry points hinders this. For example, any one with a reference to the object can lock on it without the object designer/creator knowing about it. This increases the complexity of multi-threaded solutions and might affect their correctness.
A private field is usually a better option as the compiler will enforce access restrictions to it, and it will encapsulate the locking mechanism. Using this
violates encapsulation by exposing part of your locking implementation to the public. It is also not clear that you will be acquiring a lock on this
unless it has been documented. Even then, relying on documentation to prevent a problem is sub-optimal.
Finally, there is the common misconception that lock(this)
actually modifies the object passed as a parameter, and in some way makes it read-only or inaccessible. This is false. The object passed as a parameter to lock
merely serves as a key. If a lock is already being held on that key, the lock cannot be made; otherwise, the lock is allowed.
This is why it's bad to use strings as the keys in lock
statements, since they are immutable and are shared/accessible across parts of the application. You should use a private variable instead, an Object
instance will do nicely.
Run the following C# code as an example.
public class Person
{
public int Age { get; set; }
public string Name { get; set; }
public void LockThis()
{
lock (this)
{
System.Threading.Thread.Sleep(10000);
}
}
}
class Program
{
static void Main(string[] args)
{
var nancy = new Person {Name = "Nancy Drew", Age = 15};
var a = new Thread(nancy.LockThis);
a.Start();
var b = new Thread(Timewarp);
b.Start(nancy);
Thread.Sleep(10);
var anotherNancy = new Person { Name = "Nancy Drew", Age = 50 };
var c = new Thread(NameChange);
c.Start(anotherNancy);
a.Join();
Console.ReadLine();
}
static void Timewarp(object subject)
{
var person = subject as Person;
if (person == null) throw new ArgumentNullException("subject");
// A lock does not make the object read-only.
lock (person.Name)
{
while (person.Age <= 23)
{
// There will be a lock on 'person' due to the LockThis method running in another thread
if (Monitor.TryEnter(person, 10) == false)
{
Console.WriteLine("'this' person is locked!");
}
else Monitor.Exit(person);
person.Age++;
if(person.Age == 18)
{
// Changing the 'person.Name' value doesn't change the lock...
person.Name = "Nancy Smith";
}
Console.WriteLine("{0} is {1} years old.", person.Name, person.Age);
}
}
}
static void NameChange(object subject)
{
var person = subject as Person;
if (person == null) throw new ArgumentNullException("subject");
// You should avoid locking on strings, since they are immutable.
if (Monitor.TryEnter(person.Name, 30) == false)
{
Console.WriteLine("Failed to obtain lock on 50 year old Nancy, because Timewarp(object) locked on string \"Nancy Drew\".");
}
else Monitor.Exit(person.Name);
if (Monitor.TryEnter("Nancy Drew", 30) == false)
{
Console.WriteLine("Failed to obtain lock using 'Nancy Drew' literal, locked by 'person.Name' since both are the same object thanks to inlining!");
}
else Monitor.Exit("Nancy Drew");
if (Monitor.TryEnter(person.Name, 10000))
{
string oldName = person.Name;
person.Name = "Nancy Callahan";
Console.WriteLine("Name changed from '{0}' to '{1}'.", oldName, person.Name);
}
else Monitor.Exit(person.Name);
}
}
Console output

What you could also have a look at is the exposed method Application->loadEnvironmentFrom($file)
I needed one application to run on multiple subdomains. So in bootstrap/app.php
I added something like:
$envFile = '.env';
// change $envFile conditionally here
$app->loadEnvironmentFrom($envFile);
There is an easy workaround for this problem
What you need to do, is format your dates as DD/MM/YYYY (or whichever way around you like)
Insert a column next to the time and date columns, put a formula in this column that adds them together. e.g. =A5+B5.
Format this inserted column into DD/MM/YYYY hh:mm:ss which can be found in the custom category on the formatting section
Plot a scatter graph

If you are unhappy with this workaround, learn to use GNUplot :)
By process (in the JSF specification it's called execute) you tell JSF to limit the processing to component that are specified every thing else is just ignored.
update indicates which element will be updated when the server respond back to you request.
@all : Every component is processed/rendered.
@this: The requesting component with the execute attribute is processed/rendered.
@form : The form that contains the requesting component is processed/rendered.
@parent: The parent that contains the requesting component is processed/rendered.
With Primefaces you can even use JQuery selectors, check out this blog: http://blog.primefaces.org/?p=1867
you can do it simpler without jquery
location = "https://example.com/" + txt.value
function send() {_x000D_
location = "https://example.com/" + txt.value;_x000D_
}
_x000D_
<form id="abc">_x000D_
<input type="text" id="txt" />_x000D_
</form>_x000D_
_x000D_
<button onclick="send()">Send</button>

From Firefox 33 onwards you can call getBoundingClientRect() and it will work normally, i.e. in the question above it will return 300 x 100.
Firefox 33 will be released on 14th October 2014 but the fix is already in Firefox nightlies if you want to try it out.
The error TypeError: 'numpy.ndarray' object is not callable
means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:
In [16]: import numpy as np
In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()
TypeError: 'numpy.ndarray' object is not callable
If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean
or pd.rolling_std
to a numpy array earlier in your code.
What I mean is something like this:
In [1]: import numpy as np
In [2]: import pandas as pd
In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan, nan, nan])
In [4]: pd.rolling_mean = np.array([1,2,3])
In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
TypeError: 'numpy.ndarray' object is not callable
So, basically you need to search the rest of your codebase for pd.rolling_mean = ...
and/or pd.rolling_std = ...
to see where you may have overwritten them.
reload(pd)
just before your snippet, which should make it run by restoring the value of pd
to what you originally imported it as, but I still highly recommend that you try to find where you may have reassigned the given functions.
len(response['Items'])
will give you the count of the filtered rows
where,
fe = Key('entity').eq('tesla')
response = table.scan(FilterExpression=fe)
This works well for me:
jQuery(document).ready(function($) {
var intputElements = document.getElementsByTagName("INPUT");
for (var i = 0; i < intputElements.length; i++) {
intputElements[i].oninvalid = function (e) {
e.target.setCustomValidity("");
if (!e.target.validity.valid) {
if (e.target.name == "email") {
e.target.setCustomValidity("Please enter a valid email address.");
} else {
e.target.setCustomValidity("Please enter a password.");
}
}
}
}
});
and the form I'm using it with (truncated):
<form id="welcome-popup-form" action="authentication" method="POST">
<input type="hidden" name="signup" value="1">
<input type="email" name="email" id="welcome-email" placeholder="Email" required></div>
<input type="password" name="passwd" id="welcome-passwd" placeholder="Password" required>
<input type="submit" id="submitSignup" name="signup" value="SUBMIT" />
</form>
Interesting question!
capitalize
transforms every first letter of a word to uppercase, but it does not transform the other letters to lowercase. Not even the :first-letter
pseudo-class will cut it (because it applies to the first letter of each element, not each word), and I can't see a way of combining lowercase and capitalize to get the desired outcome.
So as far as I can see, this is indeed impossible to do with CSS.
@Harmen shows good-looking PHP and jQuery workarounds in his answer.
Tracing helped me find what the problem was (Thank you Fabian for that suggestion). I found with further testing that I could get the client certificate to work on another server (Windows Server 2012). I was testing this on my development machine (Window 7) so I could debug this process. So by comparing the trace to an IIS Server that worked and one that did not I was able to pinpoint the relevant lines in the trace log. Here is a portion of a log where the client certificate worked. This is the setup right before the send
System.Net Information: 0 : [17444] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=CredentialsNeeded).
System.Net Information: 0 : [17444] SecureChannel#54718731 - We have user-provided certificates. The server has not specified any issuers, so try all the certificates.
System.Net Information: 0 : [17444] SecureChannel#54718731 - Selected certificate:
Here is what the trace log looked like on the machine where the client certificate failed.
System.Net Information: 0 : [19616] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=CredentialsNeeded).
System.Net Information: 0 : [19616] SecureChannel#54718731 - We have user-provided certificates. The server has specified 137 issuer(s). Looking for certificates that match any of the issuers.
System.Net Information: 0 : [19616] SecureChannel#54718731 - Left with 0 client certificates to choose from.
System.Net Information: 0 : [19616] Using the cached credential handle.
Focusing on the line that indicated the server specified 137 issuers I found this Q&A that seemed similar to my issue. The solution for me was not the one marked as an answer since my certificate was in the trusted root. The answer is the one under it where you update the registry. I just added the value to the registry key.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
Value name: SendTrustedIssuerList Value type: REG_DWORD Value data: 0 (False)
After adding this value to the registry it started to work on my Windows 7 machine. This appears to be a Windows 7 issue.
Make sure SSL is enabled for your server!
I got this error when trying to use a HTTPS configuration file on my local box which doesn't have that certificate. I was trying to do local testing - by converting some of the bindings from HTTPS to HTTP. I thought it would be easier to do this than try to install a self signed certificate for local testing.
Turned out I was getting this error becasue I didn't have SSL enabled on my local IIS even though I wasn't intending on actually using it.
There was something in the configuration for HTTPS. Creating a self signed cert in IIS7 allowed HTTP to then work :-)
Had the same problem, but solved it in a different way. It might not be the best solution, but its a solution.
in app.config:
<add key="errorMailFirst" value="[email protected]"/>
<add key="errorMailSeond" value="[email protected]"/>
Then in my configuration wrapper class, I add a method to search keys.
public List<string> SearchKeys(string searchTerm)
{
var keys = ConfigurationManager.AppSettings.Keys;
return keys.Cast<object>()
.Where(key => key.ToString().ToLower()
.Contains(searchTerm.ToLower()))
.Select(key => ConfigurationManager.AppSettings.Get(key.ToString())).ToList();
}
For anyone reading this, i agree that creating your own custom configuration section is cleaner, and more secure, but for small projects, where you need something quick, this might solve it.
Perhaps the two most efficient ways to find the last index:
def rindex(lst, value):
lst.reverse()
i = lst.index(value)
lst.reverse()
return len(lst) - i - 1
def rindex(lst, value):
return len(lst) - operator.indexOf(reversed(lst), value) - 1
Both take only O(1) extra space and the two in-place reversals of the first solution are much faster than creating a reverse copy. Let's compare it with the other solutions posted previously:
def rindex(lst, value):
return len(lst) - lst[::-1].index(value) - 1
def rindex(lst, value):
return len(lst) - next(i for i, val in enumerate(reversed(lst)) if val == value) - 1
Benchmark results, my solutions are the red and green ones:
This is for searching a number in a list of a million numbers. The x-axis is for the location of the searched element: 0% means it's at the start of the list, 100% means it's at the end of the list. All solutions are fastest at location 100%, with the two reversed
solutions taking pretty much no time for that, the double-reverse solution taking a little time, and the reverse-copy taking a lot of time.
A closer look at the right end:
At location 100%, the reverse-copy solution and the double-reverse solution spend all their time on the reversals (index()
is instant), so we see that the two in-place reversals are about seven times as fast as creating the reverse copy.
The above was with lst = list(range(1_000_000, 2_000_001))
, which pretty much creates the int objects sequentially in memory, which is extremely cache-friendly. Let's do it again after shuffling the list with random.shuffle(lst)
(probably less realistic, but interesting):
All got a lot slower, as expected. The reverse-copy solution suffers the most, at 100% it now takes about 32 times (!) as long as the double-reverse solution. And the enumerate
-solution is now second-fastest only after location 98%.
Overall I like the operator.indexOf
solution best, as it's the fastest one for the last half or quarter of all locations, which are perhaps the more interesting locations if you're actually doing rindex
for something. And it's only a bit slower than the double-reverse solution in earlier locations.
All benchmarks done with CPython 3.9.0 64-bit on Windows 10 Pro 1903 64-bit.
Try this Query
select NUM, count(1) as count
from tbl
where num = 1
group by NUM

Thanks Jahmic for the answer. Worked properly for me.
another useful code snippet that read the values and return a string:
public static string ReadSetting(string key)
{
System.Configuration.Configuration cfg = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
System.Configuration.AppSettingsSection appSettings = (System.Configuration.AppSettingsSection)cfg.GetSection("appSettings");
return appSettings.Settings[key].Value;
}
Sounds like you're doing this:
0..10.to_a
The warning is from Fixnum#to_a, not from Range#to_a. Try this instead:
(0..10).to_a
in eloquent you can use this
$users = User::select('name')->groupBy('name')->get()->toArray() ;
groupBy is actually fetching the distinct values, in fact the groupBy will categorize the same values, so that we can use aggregate functions on them. but in this scenario we have no aggregate functions, we are just selecting the value which will cause the result to have distinct values

You have to pass the CancellationToken
to the Task, which will periodically monitors the token to see whether cancellation is requested.
// CancellationTokenSource provides the token and have authority to cancel the token
CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();
CancellationToken token = cancellationTokenSource.Token;
// Task need to be cancelled with CancellationToken
Task task = Task.Run(async () => {
while(!token.IsCancellationRequested) {
Console.Write("*");
await Task.Delay(1000);
}
}, token);
Console.WriteLine("Press enter to stop the task");
Console.ReadLine();
cancellationTokenSource.Cancel();
In this case, the operation will end when cancellation is requested and the Task
will have a RanToCompletion
state. If you want to be acknowledged that your task has been cancelled, you have to use ThrowIfCancellationRequested
to throw an OperationCanceledException
exception.
Task task = Task.Run(async () =>
{
while (!token.IsCancellationRequested) {
Console.Write("*");
await Task.Delay(1000);
}
token.ThrowIfCancellationRequested();
}, token)
.ContinueWith(t =>
{
t.Exception?.Handle(e => true);
Console.WriteLine("You have canceled the task");
},TaskContinuationOptions.OnlyOnCanceled);
Console.WriteLine("Press enter to stop the task");
Console.ReadLine();
cancellationTokenSource.Cancel();
task.Wait();
Hope this helps to understand better.
You're right, no API at all that I'm aware to export PrivateKey marked as non-exportable. But if you patch (in memory) normal APIs, you can use the normal way to export :)
There is a new version of mimikatz that also support CNG Export (Windows Vista / 7 / 2008 ...)
Run it and enter the following commands in its prompt:
privilege::debug
(unless you already have it or target only CryptoApi)crypto::patchcng
(nt 6) and/or crypto::patchcapi
(nt 5 & 6)crypto::exportCertificates
and/or crypto::exportCertificates CERT_SYSTEM_STORE_LOCAL_MACHINE
The exported .pfx files are password protected with the password "mimikatz"

I'm not familiar with the async keyword (is this specific to Silverlight or a new feature in the beta version of Visual Studio?), but I think I can give you an idea of why you can't do this.
If I do:
var o = new MyObject();
MessageBox(o.SomeProperty.ToString());
o may not be done initializing before the next line of code runs. An instantiation of your object cannot be assigned until your constructor is completed, and making the constructor asynchronous wouldn't change that so what would be the point? However, you could call an asynchronous method from your constructor and then your constructor could complete and you would get your instantiation while the async method is still doing whatever it needs to do to setup your object.
LinkedHashMap
is precisely what you're looking for.
It is exactly like HashMap
, except that when you iterate over it, it presents the items in the insertion order.
If you use numpy
, this is easy:
slice = arr[:2,:2]
or if you want the 0's,
slice = arr[0:2,0:2]
You'll get the same result.
*note that slice
is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".
Another way, if you're working with lists of lists*:
slice = [arr[i][0:2] for i in range(0,2)]
(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)]
would also work.).
What I did here is that I take each desired row 1 at a time (arr[i]
). I then slice the columns I want out of that row and add it to the list that I'm building.
If you naively try: arr[0:2]
You get the first 2 rows which if you then slice again arr[0:2][0:2]
, you're just slicing the first two rows over again.
*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.
Use this Command
if(JButton.getModel().isArmed()){
//your code here.
//your code will be only executed if JButton is clicked.
}
Answer is short. But it worked for me. Use the variable name of your button instead of "JButton".
Lets assume
private string isChecked;
private webElement e;
isChecked =e.findElement(By.tagName("input")).getAttribute("checked");
if(isChecked=="true")
{
}
else
{
}
Hope this answer will be help for you. Let me know, if have any clarification in CSharp Selenium web driver.
There are lot of different Timers in the .NET BCL:
When to use which?
System.Timers.Timer
, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.System.Threading.Timer
, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.System.Windows.Forms.Timer
(.NET Framework only), a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment; it executes on the UI thread.System.Web.UI.Timer
(.NET Framework only), an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.System.Windows.Threading.DispatcherTimer
, a timer that's integrated into the Dispatcher queue. This timer is processed with a specified priority at a specified time interval.Some of them needs explicit Start
call to begin ticking (for example System.Timers
, System.Windows.Forms
). And an explicit Stop
to finish ticking.
using TimersTimer = System.Timers.Timer;
static void Main(string[] args)
{
var timer = new TimersTimer(1000);
timer.Elapsed += (s, e) => Console.WriteLine("Beep");
Thread.Sleep(1000); //1 second delay
timer.Start();
Console.ReadLine();
timer.Stop();
}
While on the other hand there are some Timers (like: System.Threading
) where you don't need explicit Start
and Stop
calls. (The provided delegate will run a background thread.) Your timer will tick until you or the runtime dispose it.
So, the following two versions will work in the same way:
using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
Console.ReadLine();
}
using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
StartTimer();
Console.ReadLine();
}
static void StartTimer()
{
var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}
But if your timer
disposed then it will stop ticking obviously.
using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
StartTimer();
GC.Collect(0);
Console.ReadLine();
}
static void StartTimer()
{
var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

To expand on @PhiLho answer, you can center a very large image (or any size image) on a page with:
{
background-image: url(_images/home.jpg);
background-repeat:no-repeat;
background-position:center;
}
Or you could use a smaller image with a background color that matches the background of the image (if it is a solid color). This may or may not suit your purposes.
{
background-color: green;
background-image: url(_images/home.jpg);
background-repeat:no-repeat;
background-position:center;
}
I installed using the command:
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--with-system-ffi \
--enable-unicode=ucs4 &&
make
Now, as the root user:
make install &&
chmod -v 755 /usr/lib/libpython2.7.so.1.0
Then I tried to execute python and got the error:
/usr/local/bin/python: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
Then, I logged out from root user and again tried to execute the Python and it worked successfully.
a.mean()
takes an axis
argument:
In [1]: import numpy as np
In [2]: a = np.array([[40, 10], [50, 11]])
In [3]: a.mean(axis=1) # to take the mean of each row
Out[3]: array([ 25. , 30.5])
In [4]: a.mean(axis=0) # to take the mean of each col
Out[4]: array([ 45. , 10.5])
Or, as a standalone function:
In [5]: np.mean(a, axis=1)
Out[5]: array([ 25. , 30.5])
The reason your slicing wasn't working is because this is the syntax for slicing:
In [6]: a[:,0].mean() # first column
Out[6]: 45.0
In [7]: a[:,1].mean() # second column
Out[7]: 10.5

I just realized that the hist
documentation is explicit about what to do when you already have an np.histogram
counts, bins = np.histogram(data)
plt.hist(bins[:-1], bins, weights=counts)
The important part here is that your counts are simply the weights. If you do it like that, you don't need the bar function anymore
In Python, at least for me, this was very wft! the first time I saw it:
>>> "ja " * 5
'ja ja ja ja ja '
You can multiply strings! WTF??
PS: I think this is because x * n
means: n times x
so, 5 times "ja "
is "ja ""ja ""ja ""ja ""ja "
and because you can concatenate strings like this:
>>> "ja ""ja ""ja ""ja ""ja "
'ja ja ja ja ja '
That two codes have the same result (and maybe are just the same)

This should do it:
import (
"fmt"
"log"
"os"
"path/filepath"
)
func main() {
dir, err := filepath.Abs(filepath.Dir(os.Args[0]))
if err != nil {

}
fmt.Println(dir)
}
You could put an application.properties file in your test/resources folder. There you set
spring.profiles.active=test
This is kind of a default test profile while running tests.
or you can try this:
string1 = 'Hello \n World'
tmp = string1.split()
string2 = ' '.join(tmp)
I've had the same requirement, but the solutions here didn't quite get me across the line, due to the source of data for the recyclerView.
I was extracting the RecyclerViews' LinearLayoutManager state in onPause()
private Parcelable state;
Public void onPause() {
state = mLinearLayoutManager.onSaveInstanceState();
}
Parcelable state
is saved in onSaveInstanceState(Bundle outState)
, and extracted again in onCreate(Bundle savedInstanceState)
, when savedInstanceState != null
.
However, the recyclerView adapter is populated and updated by a ViewModel LiveData object returned by a DAO call to a Room database.
mViewModel.getAllDataToDisplay(mSelectedData).observe(this, new Observer<List<String>>() {
@Override
public void onChanged(@Nullable final List<String> displayStrings) {
mAdapter.swapData(displayStrings);
mLinearLayoutManager.onRestoreInstanceState(state);
}
});
I eventually found that restoring the instance state directly after the data is set in the adapter would keep the scroll-state across rotations.
I suspect this either is because the LinearLayoutManager
state that I'd restored was being overwritten when the data was returned by the database call, or the restored state was meaningless against an 'empty' LinearLayoutManager.
If the adapter data is available directly (ie not contigent on a database call), then restoring the instance state on the LinearLayoutManager can be done after the adapter is set on the recyclerView.
The distinction between the two scenarios held me up for ages.
Use date() function to get the desired date
<?php
// set default timezone
date_default_timezone_set('UTC');
//define date and time
$strtotime = 1307595105;
// output
echo date('d M Y H:i:s',$strtotime);
// more formats
echo date('c',$strtotime); // ISO 8601 format
echo date('r',$strtotime); // RFC 2822 format
?>

I solved this problem using the split npm module. Pipe your stream into split, and it will "Break up a stream and reassemble it so that each line is a chunk".
Sample code:
var fs = require('fs')
, split = require('split')
;
var stream = fs.createReadStream(filePath, {flags: 'r', encoding: 'utf-8'});
var lineStream = stream.pipe(split());
linestream.on('data', function(chunk) {
var json = JSON.parse(chunk);
// ...
});
I solved problem like yours by this commands:
git reset --hard HEAD^
git push -f <remote> <local branch>:<remote branch>
Do both in a single pass with:
find -type f ... -o -type d ...
As in, find type f OR type d, and do the first ... for files and the second ... for dirs. Specifically:
find -type f -exec chmod --changes 644 {} + -o -type d -exec chmod --changes 755 {} +
Leave off the --changes
if you want it to work silently.
Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent
attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)
Instead, the best approach would be to:
To allow each panel to toggle individually, on the data-toggle="collapse"
element, set the data-target
attribute to the .collapse
panel ID selector (instead of setting the data-parent
attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.
Roughly, each panel should look like this:
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title"
data-toggle="collapse"
data-target="#collapseOne">
Collapsible Group Item #1
</h4>
</div>
<div id="collapseOne"
class="panel-collapse collapse">
<div class="panel-body"></div>
</div>
</div>
To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:
$('#accordion').on('show.bs.collapse', function () {
if (active) $('#accordion .in').collapse('hide');
});
Then use show
and hide
to toggle the visibility of each of the panels and data-toggle
to enable and disable the controls.
$('#collapse-init').click(function () {
if (active) {
active = false;
$('.panel-collapse').collapse('show');
$('.panel-title').attr('data-toggle', '');
$(this).text('Enable accordion behavior');
} else {
active = true;
$('.panel-collapse').collapse('hide');
$('.panel-title').attr('data-toggle', 'collapse');
$(this).text('Disable accordion behavior');
}
});

I found the following comparison helpful:
str(f1) == str(f2)
Your struct can have methods and properties... why not try
public struct MyStruct {
public string s;
public int length { return s.Length; }
}
Correction @Guffa's answer shows that it is possible... more info here: http://www.codeproject.com/KB/cs/Csharp_implicit_operator.aspx
n % x == 0
Means that n can be divided by x. So... for instance, in your case:
boolean isDivisibleBy20 = number % 20 == 0;
Also, if you want to check whether a number is even or odd (whether it is divisible by 2 or not), you can use a bitwise operator:
boolean even = (number & 1) == 0;
boolean odd = (number & 1) != 0;
There's some duplicates that touch on this, and nobody really expounds on it. I'll borrow the accepted answer example to illustrate
http.open('POST', url, true);
http.send('lorem=ipsum&name=binny');
I oversimplified this (I use http.onload(function() {})
instead of that answer's older methodology) for the sake of illustration. If you use this as-is, you'll find your server is probably interpreting the POST body as a string and not actual key=value
parameters (i.e. PHP won't show any $_POST
variables). You must pass the form header in to get that, and do that before http.send()
http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
If you're using JSON and not URL-encoded data, pass application/json
instead
Explanation with an example:
Consider you have a game (iso) image in your computer.
When you run
(mount your image as a virtual drive), a virtual drive is created with all the game contents in the virtual drive and the game installation file is automatically launched. [Running your docker image - creating a container and then starting it.]
But when you stop
(similar to docker stop) it, the virtual drive still exists but stopping all the processes. [As the container exists till it is not deleted]
And when you do start
(similar to docker start), from the virtual drive the games files start its execution. [starting the existing container]
In this example - The game image is your Docker image and virtual drive is your container.
Well, you can actually send data via JavaScript - but you should know that this is the #1 exploit source in web pages as it's XSS :)
I personally would suggest to use an HTML formular instead and modify the javascript data on the server side.
But if you want to share between two pages (I assume they are not both on localhost, because that won't make sense to share between two both-backend-driven pages) you will need to specify the CORS headers to allow the browser to send data to the whitelisted domains.
These two links might help you, it shows the example via Node backend, but you get the point how it works:
And, of course, the CORS spec:

Check this code in alert box have edit textview when click OK it displays on screen using toast.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString().trim();
Toast.makeText(getApplicationContext(), value,
Toast.LENGTH_SHORT).show();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
alert.show();
}
In my case, double quotes was not a problem.
Last comma gave me same error message.
{'a':{'b':c,}}
^
To remove this comma, I wrote some simple code.
import json
with open('a.json','r') as f:
s = f.read()
s = s.replace('\t','')
s = s.replace('\n','')
s = s.replace(',}','}')
s = s.replace(',]',']')
data = json.loads(s)
And this worked for me.

If you have ejected, this is the proper way to fix this issue:
find this file config/webpackDevServer.config.js
and then inside this file find the following line:
app.use(noopServiceWorkerMiddleware());
You should change it to:
app.use(noopServiceWorkerMiddleware('/'));
For me(and probably most of you) the service worker is served at the root of the project. In case it's different for you, you can pass your base path instead.
Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.
In short, you add the selector after the URL. For example:
$('#result').load('ajax/test.html #container');
var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'
I tried using a CLR function and it was more than twice as fast as BCP. Here's my code.

SET @bcpCommand = 'bcp "SELECT blobcolumn FROM blobtable WHERE ID = ' + CAST(@FileID AS VARCHAR(20)) + '" queryout "' + @FileName + '" -T -c'
EXEC master..xp_cmdshell @bcpCommand
CLR Method:
declare @file varbinary(max) = (select blobcolumn from blobtable WHERE ID = @fileid)
declare @filepath nvarchar(4000) = N'c:\temp\' + @FileName
SELECT Master.dbo.WriteToFile(@file, @filepath, 0)
C# Code for the CLR function

using System.Data;
using System.Data.SqlTypes;
using System.IO;
using Microsoft.SqlServer.Server;
namespace BlobExport
{
public class Functions

{
try
{
if (!binary.IsNull && !path.IsNull && !append.IsNull)
{
var dir = Path.GetDirectoryName(path.Value);
if (!Directory.Exists(dir))
Directory.CreateDirectory(dir);
using (var fs = new FileStream(path.Value, append ? FileMode.Append : FileMode.OpenOrCreate))
{
byte[] byteArr = binary.Value;
for (int i = 0; i < byteArr.Length; i++)
{
fs.WriteByte(byteArr[i]);
};

return "SUCCESS";
}
else
"NULL INPUT";
}
catch (Exception ex)
{
return ex.Message;
}
}
}
}
As for Primary Key, whatever physically makes a row unique should be determined as the primary key.
For a reference as a foreign key, using an auto incrementing integer as a surrogate is a nice idea for two main reasons.
- First, there's less overhead incurred in the join usually.
- Second, if you need to update the table that contains the unique varchar then the update has to cascade down to all the child tables and update all of them as well as the indexes, whereas with the int surrogate, it only has to update the master table and it's indexes.
The drawaback to using the surrogate is that you could possibly allow changing of the meaning of the surrogate:
ex.
id value
1 A
2 B
3 C
Update 3 to D
id value
1 A
2 B
3 D
Update 2 to C
id value
1 A
2 C
3 D
Update 3 to B
id value
1 A
2 C
3 B
It all depends on what you really need to worry about in your structure and what means most.
I use
\pagenumbering{roman}
for everything in the frontmatter and then switch over to
\pagenumbering{arabic}
for the actual content. With pdftex, the page numbers come out right in the PDF file.
Random r = new Random();
int i1 = r.nextInt(80 - 65) + 65;
This gives a random integer between 65 (inclusive) and 80 (exclusive), one of 65,66,...,78,79
.
Use window.location.pathname
to get the path of the current page's URL.
name
string by space and make array of wordslet name = "My Name".split(" ").map(n => new RegExp(n));
console.log(name);
_x000D_
Result:
[/My/, /Name/]
Try $in Expressions, To include a regular expression in an $in
query expression, you can only use JavaScript regular expression objects (i.e. /pattern/ ). For example:
db.users.find({ name: { $in: name } }); // name = [/My/, /Name/]
If you use git config user.email "[email protected]"
it will be bound to the current project you are in.
That is what I do for my projects. I set the appropriate identity when I clone/init the repo. It is not fool-proof (if you forget and push before you figure it out you are hosed) but it is about as good as you can get without the ability to say git config --global user.email 'ILLEGAL_VALUE'
Actually, you can make an illegal value. Set your git config --global user.name $(perl -e 'print "x"x968;')
Then if you forget to set your non-global values you will get an error message.
[EDIT] On a different system I had to increase the number of x to 968 to get it to fail with "fatal: Impossibly long personal identifier". Same version of git. Strange.
You need to install Python's header files (python-dev package in debian/ubuntu) to compile lxml. As well as libxml2, libxslt, libxml2-dev, and libxslt-dev:
apt-get install python-dev libxml2 libxml2-dev libxslt-dev
I found a different solution to this issue. Apparently my IIS 7 did not have 32bit mode enabled in my Application Pool by default.
To enable 32bit mode, open IIS and select your Application Pool. Mine was named "ASP.NET v4.0".
Right click, go to "Advanced Settings" and change the section named:
"Enabled 32-bit Applications" to true.
Restart your web server and try again.
I found the fix from this blog reference: http://darrell.mozingo.net/2009/01/17/running-iis-7-in-32-bit-mode/
Additionally, you can change the settings on Visual Studio. In my case, I went to Tools > Options > Projects and Solutions > Web Projects
and checked Use the 64 bit version of IIS Express for web sites and projects
- This was on VS Pro 2015. Nothing else fixed it but this.
You can use this:
remoteviews.setInt(R.id.YourTextView, "setPaintFlags", Paint.STRIKE_THRU_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG);
Of course you can also add other flags from the android.graphics.Paint class.
As your clock.js is in the root, put your code as this to call your javascript in the index.html found in the folders you mentioned.
<SCRIPT LANGUAGE="JavaScript" SRC="../clock.js"></SCRIPT>
This will call the clock.js which you put in the root of your web site.

none of all above answers working good on my app
here is my working code
on your exit button:
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
ComponentName cn = intent.getComponent();
Intent mainIntent = IntentCompat.makeRestartActivityTask(cn);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
mainIntent.putExtra("close", true);
startActivity(mainIntent);
finish();
that code is to close any other activity and bring MainActivity on top now on your MainActivity:
if( getIntent().getBooleanExtra("close", false)){
finish();
}
You need to install psycopg2
Python library.
Download http://initd.org/psycopg/, then install it under Python PATH
After downloading, easily extract the tarball and:
$ python setup.py install
Or if you wish, install it by either easy_install or pip.
(I prefer to use pip over easy_install for no reason.)
$ easy_install psycopg2
$ pip install psycopg2
in settings.py

Had the error today on a 12c and none of the existing answers fit (no duplicates, no non-deterministic expressions in the WHERE clause). My case was related to that other possible cause of the error, according to Oracle's message text (emphasis below):
ORA-30926: unable to get a stable set of rows in the source tables
Cause: A stable set of rows could not be got because of large dml activity or a non-deterministic where clause.
The merge was part of a larger batch, and was executed on a live database with many concurrent users. There was no need to change the statement. I just committed the transaction before the merge, then ran the merge separately, and committed again. So the solution was found in the suggested action of the message:
Action: Remove any non-deterministic where clauses and reissue the dml.
Be careful if you have to deal with large numbers.
int[] arr = new int[]{Integer.MIN_VALUE, Integer.MIN_VALUE};
long sum = Arrays.stream(arr).sum(); // Wrong: sum == 0
The sum above is not 2 * Integer.MIN_VALUE
.
You need to do this in this case.
long sum = Arrays.stream(arr).mapToLong(Long::valueOf).sum(); // Correct
Make an object
$obj = json_decode(json_encode($need_to_json));
Show data from this $obj
$obj->{'needed'};
If you just need to resync
windows time, open an elevated command prompt and type:
w32tm /resync
C:\WINDOWS\system32>w32tm /resync
Sending resync command to local computer
The command completed successfully.
This will pop a dialog asking the user if he really wants to close or stay, with a message.
var message = "You have not filled out the form.";
window.onbeforeunload = function(event) {
var e = e || window.event;
if (e) {
e.returnValue = message;
}
return message;
};
You can then unset it before the form gets submitted or something else with
window.onbeforeunload = null;
Keep in mind that this is extremely annoying. If you are trying to force your users to fill out a form that they don't want to fill out, then you will fail: they will find a way to close the window and never come back to your mean website.
I'd check your php.ini file and verify the mysql.default_socket is set correctly and also verify that your mysqld is correctly configured with a socket file it can access. Typical default is "/tmp/mysql.sock".
You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.
That's why your example uses Active X, which bypasses the JavaScript security issues.
So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.
Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.
You could do it in one document if you had a conditional based on params sent over. Eg:
if (isset($_GET['secret_param'])) {
<run script>
} else {
<display button>
}
I think the best way though is to have two files.
Yes you only need $()
when you're using jQuery. If you want jQuery's help to do DOM things just keep this in mind.
$(this)[0] === this
Basically every time you get a set of elements back jQuery turns it into a jQuery object. If you know you only have one result, it's going to be in the first element.
$("#myDiv")[0] === document.getElementById("myDiv");
And so on...
String myText = " Hello World ";
myText = myText.trim().replace(/ +(?= )/g,'');
// Output: "Hello World"
Slf4j is a facade for the underlying logging frameworks like log4j, logback, java.util.logging.
To connect with underlying frameworks, slf4j uses a binding.
The above error is thrown if the binding jar is missed. You can download this jar and add it to classpath.
For maven dependency,
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.21</version>
</dependency>
This dependency in addition to slf4j-log4j12-1.7.21.jar,it will pull slf4j-api-1.7.21.jar as well as log4j-1.2.17.jar into your project
Reference: http://www.slf4j.org/manual.html
If no file available for download, I needed to disable the asp:linkButton, change it to grey and eliminate the underline on the hover. This worked:
.disabled {
color: grey;
text-decoration: none !important;
}
LinkButton button = item.FindControl("lnkFileDownload") as LinkButton;
button.Enabled = false;
button.CssClass = "disabled";
You might want to consider Twisted which is a Python networking library that implements the Reactor Pattern.
from twisted.internet import task, reactor
timeout = 60.0 # Sixty seconds
def doWork():
#do work here
pass
l = task.LoopingCall(doWork)
l.start(timeout) # call every sixty seconds
reactor.run()
While "while True: sleep(60)" will probably work Twisted probably already implements many of the features that you will eventually need (daemonization, logging or exception handling as pointed out by bobince) and will probably be a more robust solution
Often this question is asked in the context of Ron de Bruin's RangeToHTML
function, which creates an HTML PublishObject
from an Excel.Range
, extracts that via FSO, and inserts the resulting stream HTML in to the email's HTMLBody
. In doing so, this removes the default signature (the RangeToHTML
function has a helper function GetBoiler
which attempts to insert the default signature).
Unfortunately, the poorly-documented Application.CommandBars
method is not available via Outlook:
wdDoc.Application.CommandBars.ExecuteMso "PasteExcelTableSourceFormatting"
It will raise a runtime 6158:
But we can still leverage the Word.Document
which is accessible via the MailItem.GetInspector
method, we can do something like this to copy & paste the selection from Excel to the Outlook email body, preserving your default signature (if there is one).
Dim rng as Range
Set rng = Range("A1:F10") 'Modify as needed
With OutMail
.To = "[email protected]"
.BCC = ""
.Subject = "Subject"
.Display
Dim wdDoc As Object '## Word.Document
Dim wdRange As Object '## Word.Range
Set wdDoc = OutMail.GetInspector.WordEditor
Set wdRange = wdDoc.Range(0, 0)
wdRange.InsertAfter vbCrLf & vbCrLf
'Copy the range in-place
rng.Copy
wdRange.Paste
End With
Note that in some cases this may not perfectly preserve the column widths or in some instances the row heights, and while it will also copy shapes and other objects in the Excel range, this may also cause some funky alignment issues, but for simple tables and Excel ranges, it is very good:
shape
is a property of both numpy ndarray's and matrices.
A.shape
will return a tuple (m, n), where m is the number of rows, and n is the number of columns.
In fact, the numpy matrix
object is built on top of the ndarray
object, one of numpy's two fundamental objects (along with a universal function object), so it inherits from ndarray
No shadow and no rounded borders in the bar
You are using an image so the easiest solution is row your boat with the flow,
You cannot give heights manually,yes you can but make sure it gets enough space to show your full image view there
android:layout_height="wrap_content"
for SeekBar
I am no good with Photoshop but I managed to edit a background one for a test
seekbar_brown_to_show_progress.png
<SeekBar
android:splitTrack="false" // for unwanted white space in thumb
android:id="@+id/seekBar_luminosite"
android:layout_width="250dp" // use your own size
android:layout_height="wrap_content"
android:minHeight="10dp"
android:minWidth="15dp"
android:maxHeight="15dp"
android:maxWidth="15dp"
android:progress="50"
android:progressDrawable="@drawable/custom_seekbar_progress"
android:thumb="@drawable/custom_thumb" />
custom_seekbar_progress.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@android:id/background"
android:drawable="@drawable/seekbar" />
<item android:id="@android:id/progress">
<clip android:drawable="@drawable/seekbar_brown_to_show_progress" />
</item>
</layer-list>
custom_thumb.xml is same as yours
Finally android:splitTrack="false"
will remove the unwanted white space in your thumb
Let's have a look at the output :
Like the others said, you probably missunderstood the idea of a unique id. All I have to add is, that I do not like the idea of using "value" as the identifying property here, as it may change over time (i.e. if you want to provide multiple languages).
<input id='submit_tea' type='submit' name = 'submit_tea' value = 'Tea' />
<input id='submit_coffee' type='submit' name = 'submit_coffee' value = 'Coffee' />
and in your php script
if( array_key_exists( 'submit_tea', $_POST ) )
{
// handle tea
}
if( array_key_exists( 'submit_coffee', $_POST ) )
{
// handle coffee
}
Additionally, you can add something like if( 'POST' == $_SERVER[ 'REQUEST_METHOD' ] )
if you want to check if data was acctually posted.
The approach I suggest is a bit verbose but I found it to scale pretty well into complex apps. When you want to show a modal, fire an action describing which modal you'd like to see:
this.props.dispatch({
type: 'SHOW_MODAL',
modalType: 'DELETE_POST',
modalProps: {
postId: 42
}
})
(Strings can be constants of course; I’m using inline strings for simplicity.)
Then make sure you have a reducer that just accepts these values:
const initialState = {
modalType: null,
modalProps: {}
}
function modal(state = initialState, action) {
switch (action.type) {
case 'SHOW_MODAL':
return {
modalType: action.modalType,
modalProps: action.modalProps
}
case 'HIDE_MODAL':
return initialState
default:
return state
}
}
/* .... */
const rootReducer = combineReducers({
modal,
/* other reducers */
})
Great! Now, when you dispatch an action, state.modal
will update to include the information about the currently visible modal window.
At the root of your component hierarchy, add a <ModalRoot>
component that is connected to the Redux store. It will listen to state.modal
and display an appropriate modal component, forwarding the props from the state.modal.modalProps
.
// These are regular React components we will write soon
import DeletePostModal from './DeletePostModal'
import ConfirmLogoutModal from './ConfirmLogoutModal'
const MODAL_COMPONENTS = {
'DELETE_POST': DeletePostModal,
'CONFIRM_LOGOUT': ConfirmLogoutModal,
/* other modals */
}
const ModalRoot = ({ modalType, modalProps }) => {
if (!modalType) {
return <span /> // after React v15 you can return null here
}
const SpecificModal = MODAL_COMPONENTS[modalType]
return <SpecificModal {...modalProps} />
}
export default connect(
state => state.modal
)(ModalRoot)
What have we done here? ModalRoot
reads the current modalType
and modalProps
from state.modal
to which it is connected, and renders a corresponding component such as DeletePostModal
or ConfirmLogoutModal
. Every modal is a component!
There are no general rules here. They are just React components that can dispatch actions, read something from the store state, and just happen to be modals.
For example, DeletePostModal
might look like:
import { deletePost, hideModal } from '../actions'
const DeletePostModal = ({ post, dispatch }) => (
<div>
<p>Delete post {post.name}?</p>
<button onClick={() => {
dispatch(deletePost(post.id)).then(() => {
dispatch(hideModal())
})
}}>
Yes
</button>
<button onClick={() => dispatch(hideModal())}>
Nope
</button>
</div>
)
export default connect(
(state, ownProps) => ({
post: state.postsById[ownProps.postId]
})
)(DeletePostModal)
The DeletePostModal
is connected to the store so it can display the post title and works like any connected component: it can dispatch actions, including hideModal
when it is necessary to hide itself.
It would be awkward to copy-paste the same layout logic for every “specific” modal. But you have components, right? So you can extract a presentational <Modal>
component that doesn’t know what particular modals do, but handles how they look.
Then, specific modals such as DeletePostModal
can use it for rendering:
import { deletePost, hideModal } from '../actions'
import Modal from './Modal'
const DeletePostModal = ({ post, dispatch }) => (
<Modal
dangerText={`Delete post ${post.name}?`}
onDangerClick={() =>
dispatch(deletePost(post.id)).then(() => {
dispatch(hideModal())
})
})
/>
)
export default connect(
(state, ownProps) => ({
post: state.postsById[ownProps.postId]
})
)(DeletePostModal)
It is up to you to come up with a set of props that <Modal>
can accept in your application but I would imagine that you might have several kinds of modals (e.g. info modal, confirmation modal, etc), and several styles for them.
The last important part about modals is that generally we want to hide them when the user clicks outside or presses Escape.
Instead of giving you advice on implementing this, I suggest that you just don’t implement it yourself. It is hard to get right considering accessibility.
Instead, I would suggest you to use an accessible off-the-shelf modal component such as react-modal
. It is completely customizable, you can put anything you want inside of it, but it handles accessibility correctly so that blind people can still use your modal.
You can even wrap react-modal
in your own <Modal>
that accepts props specific to your applications and generates child buttons or other content. It’s all just components!
There is more than one way to do it.
Some people don’t like the verbosity of this approach and prefer to have a <Modal>
component that they can render right inside their components with a technique called “portals”. Portals let you render a component inside yours while actually it will render at a predetermined place in the DOM, which is very convenient for modals.
In fact react-modal
I linked to earlier already does that internally so technically you don’t even need to render it from the top. I still find it nice to decouple the modal I want to show from the component showing it, but you can also use react-modal
directly from your components, and skip most of what I wrote above.
I encourage you to consider both approaches, experiment with them, and pick what you find works best for your app and for your team.
You need to specify workseet. Change line
If Worksheet.Cells(i, 1).Value = "X" Then
to
If Worksheets("Sheet2").Cells(i, 1).Value = "X" Then
UPD:
Try to use following code (but it's not the best approach. As @SiddharthRout suggested, consider about using Autofilter):
Sub LastRowInOneColumn()
Dim LastRow As Long
Dim i As Long, j As Long
'Find the last used row in a Column: column A in this example
With Worksheets("Sheet2")
LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
End With
MsgBox (LastRow)
'first row number where you need to paste values in Sheet1'
With Worksheets("Sheet1")
j = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
End With
For i = 1 To LastRow
With Worksheets("Sheet2")
If .Cells(i, 1).Value = "X" Then
.Rows(i).Copy Destination:=Worksheets("Sheet1").Range("A" & j)
j = j + 1
End If
End With
Next i
End Sub
Update: On v8.0.15 (maybe this version) the PASSWORD()
function does not work.
You have to:
sudo mysqld_safe --skip-grant-tables
mysql -u root
UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;
exit;
mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
Try this
{% if var in ['foo', 'bar', 'beer'] %}
...
{% endif %}
In my case the error 1067 was caused with a specific version of Tomcat 7.0.96 32-bit in combination with AdoptOpenJDK. Spent two hours on it, un-installing, re-installing and trying different Java settings but Tomcat would not start. See... ASF Bugzilla – Bug 63625 seems to point at the issue though they refer to seeing a different error.
I tried 7.0.99 32-bit and it started straight away with the same AdoptOpenJDK 32-bit binary install.
Based on @MarcGravell's answer, here's a version that works in Unity C#.
ObjectsClass foo = this;
foreach(var prop in foo.GetType().GetProperties()) {
Debug.Log("{0}={1}, " + prop.Name + ", " + prop.GetValue(foo, null));
}
