A schema and database users are same but if schema has owned database objects and they can do anything their object but user just access the objects, They can't DO any DDL operations until schema user give you the proper privileges.
There are two types of drop down lists available (I am not sure since which version).
ActiveX Drop Down
You can set the column widths, so your hidden column can be set to 0.
Form Drop Down
You could set the drop down range to a hidden sheet and reference the cell adjacent to the selected item. This would also work with the ActiveX type control.
This should work with any kind of database.
You can use numpy's slicing, simply start:stop:step
.
>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])
This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2] # O(1), constant time
>>> b[:] = 0 # modifying the view changes original array
>>> a # original array is modified
array([0, 2, 0, 4, 0])
so if either of the above things are a problem, you can make a copy explicitly:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy() # explicit copy, O(n)
>>> b[:] = 0 # modifying the copy
>>> a # original is intact
array([1, 2, 3, 4, 5])
This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.
You will not have this problem if you're using MySQL 5.7.7+ or MariaDB 10.2.2+.
To update MariaDB on your Mac using Brew first unlink the current one:
brew unlink mariadb
and then install a dev one using brew install mariadb --devel
After installation is done stop/start the service running:
brew services stop mariadb
brew services start mariadb
Current dev version is 10.2.3. After the installation is finished you won't have to worry about this anymore and you can use utf8mb4 (that is now a default in Laravel 5.4) without switching back to utf8 nor editing AppServiceProvider as proposed in the Laravel documentation: https://laravel.com/docs/master/releases#laravel-5.4 (scroll down to: Migration Default String Length)
-- Login to psql and run the following
-- What is the result?
SELECT MAX(id) FROM your_table;

-- (wise to run a quick pg_dump first...)

if you have only space problem in url. I have used below code and it work fine
String url;
URL myUrl = new URL(url.replace(" ","%20"));
example : url is
www.xyz.com?para=hello sir
then output of muUrl is
www.xyz.com?para=hello%20sir
you shoud do like this form your code
DataGridView.DataSource = yourlist;
DataGridView.DataBind();
I'm assuming you have a typo in your get statement and that it should be test1.get(key). If so, I'm not sure why it is not returning an ArrayList unless you are not putting in the correct type in the map in the first place.
This should work:
// populate the map
Map<String, List<String>> test1 = new LinkedHashMap<String, List<String>>();
test1.put("key1", new ArrayList<String>());
test1.put("key2", new ArrayList<String>());
// loop over the set using an entry set
for( Map.Entry<String,List<String>> entry : test1.entrySet()){
String key = entry.getKey();
List<String>value = entry.getValue();
// ...
}
or you can use
// second alternative - loop over the keys and get the value per key
for( String key : test1.keySet() ){
List<String>value = test1.get(key);
// ...
}
You should use the interface names when declaring your vars (and in your generic params) unless you have a very specific reason why you are defining using the implementation.
socket.isConnected()
returns always true once the client connects (and even after the disconnect) weird !!socket.getInputStream().read()
returns -1
if the client disconnectedsocket.getInetAddress().isReachable(int timeout)
: From isReachable(int timeout)
Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.
You can simply add onended="myFunction()"
to your video tag.
<video onended="myFunction()">
...
Your browser does not support the video tag.
</video>
<script type='text/javascript'>
function myFunction(){
console.log("The End.")
}
</script>
Head First SQL is a great introduction.
>>> ord('a')
97
>>> chr(97)
'a'
All java objects are pointer because a variable which holds address is called pointer and object hold address.so object is pointer variable.
You didn't select post_id
in the subquery. You have to select it in the subquery like this:
SELECT wp_woocommerce_order_items.order_id As No_Commande
FROM wp_woocommerce_order_items
LEFT JOIN
(
SELECT meta_value As Prenom, post_id -- <----- this
FROM wp_postmeta
WHERE meta_key = '_shipping_first_name'
) AS a
ON wp_woocommerce_order_items.order_id = a.post_id
WHERE wp_woocommerce_order_items.order_id =2198
I assume that you have a similar view regarding the zoom functionality as I have in this picture:
Now if you mark one of the Zoom In
/Zoom Out
lines and choose Add Keyboard Shortcut
:
You will find that this particular shortcut Numpad +
is already occupied so there is a conflict:
So you'll just have assign this Zoom In
/Zoom Out
to some other keyboard shortcut:
The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods
index.php
<html>
<body>
<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>
</body>
</html>
site2.php
<html>
<body>
Hello <?php echo $_POST["name"]; ?>!<br>
Your mail is <?php echo $_POST["mail"]; ?>.
</body>
</html>
output
Hello "name" !
Your email is "[email protected]" .
None of the up-voted answers here work for me. Here is a guaranteed and reasonable solution. Put this near the top of any code file that uses Promise...
declare const Promise: any;
The following is a jQuery function call:
$(...);
Which is the "jQuery function." $
is a function, and $(...)
is you calling that function.
The first parameter you've supplied is the following:
function() {}
The parameter is a function that you specified, and the $
function will call the supplied method when the DOM finishes loading.
Unfortunately we need to run docker-compose logs
separately from docker-compose run
. In order to get this to work reliably we need to suppress the docker-compose run
exit status then redirect the log and exit with the right status.
#!/bin/bash
set -euo pipefail
docker-compose run app | tee app.log || failed=yes
docker-compose logs --no-color > docker-compose.log
[[ -z "${failed:-}" ]] || exit 1
I didn't have luck with some of the above,
This was the only one that actually worked for me
ul:not(:first-of-type) {}
This worked for me when I was trying to have the first button displayed on the page not be effected by a margin-left option.
this was the option I tried first but it didn't work
ul:not(:first-child)
HTML Code:-
<input type="text" name="txt1" id="txt1" onkeypress="return AddKeyPress(event);" />
<input type="button" id="btnclick">
Java Script Code
function AddKeyPress(e) {
// look for window.event in case event isn't passed in
e = e || window.event;
if (e.keyCode == 13) {
document.getElementById('btnEmail').click();
return false;
}
return true;
}
Your Form do not have Default Submit Button
You should use any()
In [98]: a['Names'].str.contains('Mel').any()
Out[98]: True
In [99]: if a['Names'].str.contains('Mel').any():
....: print "Mel is there"
....:
Mel is there
a['Names'].str.contains('Mel')
gives you a series of bool values
In [100]: a['Names'].str.contains('Mel')
Out[100]:
0 False
1 False
2 False
3 False
4 True
Name: Names, dtype: bool

Added data from link to avoid link rot..
put this at any Console application:
string.Format("{0,3}", CultureInfo.InstalledUICulture.Parent.LCID.ToString("X")).Replace(" ", "0");
Watch the result. At mine it was "016".
Then you go to the registry at this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib
and create another one with the name you got from the string.Format result.
In my case:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\016"
and copy the info that is on any other key in this Perflib to this key you just created. Run the instalation again.

I've checked your source code and find to change to yellow you need to adds the yellow background color to : #left-padding, #right-padding, html, #hd, #main and #yui-main.

loadXMLDoc JS function should return false, otherwise it will result in postback.
You could use jquery ui's switchClass
, Heres an example:
$( "selector" ).switchClass( "oldClass", "newClass", 1000, "easeInOutQuad" );
Or see this jsfiddle.
If you want to write unit per meter (m^-1)
, use $m^{-1}$)
, which means -1
inbetween {}
Example:
plt.ylabel("Specific Storage Values ($m^{-1}$)", fontsize = 12 )
Saudate, I ran across this looking for a different problem. You most definitely can use the Sql Server Import wizard to import data into a new table. Of course, you do not wish to leave that table in the database, so my suggesting is that you import into a new table, then script the data in query manager to insert into the existing table. You can add a line to drop the temp table created by the import wizard as the last step upon successful completion of the script.
I believe your original issue is in fact related to Sql Server 64 bit and is due to your having a 32 bit Excel and these drivers don't play well together. I did run into a very similar issue when first using 64 bit excel.
The first 10 directories with the highest number of files.
dir=/ ; for i in $(ls -1 ${dir} | sort -n) ; { echo "$(find ${dir}${i} \
-type f | wc -l) => $i,"; } | sort -nr | head -10
Class selectors are prefixed with a dot. Your .find()
is missing that so jQuery thinks you're looking for <myClass>
elements.
var myVar = $("#start").find('.myClass').val();
Another solution could be use the uncommit
command to exclude specific file from current commit.
hg uncommit [file/directory]
This is very helpful when you want to keep current commit and deselect some files from commit (especially helpful for files/directories
have been deleted).
Adding android:lineSpacingMultiplier="0.8"
can make the line spacing to 80%.
You can use WhereNotIn in following way also:
ModelName::whereNotIn('book_price', [100,200])->get(['field_name1','field_name2']);
This will return collection of Record with specific fields
You should take a look at the List
object. Lists tend to be better at changing dynamically like you want. Arrays not so much...
you are using onclick
which is javascript event.
there is two ways
Javascript
<input type="button" value="Home" class="homebutton" id="btnHome"
onClick="window.location = 'http://google.com'" />
Or PHP
create another page as redirect.php and put
<?php header('location : google.com') ?>
and insert this link on any page within the same directory
<a href="redirect.php">google<a/>
hope this helps its simplest!!
In Ubuntu/Mint (Debian based)
$ sudo apt-get install php5-gd
Pure/vanilla JS solution (working example here)
// All elements with data-company="Microsoft" below "Companies"
let a = document.querySelectorAll("[data-group='Companies'] [data-company='Microsoft']");
// All elements with data-company!="Microsoft" below "Companies"
let b = document.querySelectorAll("[data-group='Companies'] :not([data-company='Microsoft'])");
In querySelectorAll you must use valid CSS selector (currently Level3)
SPEED TEST (2018.06.29) for jQuery and Pure JS: test was performed on MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit). Below screenshot shows results for fastest browser (Safari):
PureJS was faster than jQuery about 12% on Chrome, 21% on Firefox and 25% on Safari. Interestingly speed for Chrome was 18.9M operation per second, Firefox 26M, Safari 160.9M (!).
So winner is PureJS and fastest browser is Safari (more than 8x faster than Chrome!)
Here you can perform test on your machine: https://jsperf.com/js-selectors-x
Here is the easiest way I use, hope works for you,
var1 = var1 or 4
This assigns 4
to var1
only if var1
is None
, False
or 0
<a href="javascript:void(0);" (click)="onGoToPage2()">Go to Page 2</a>
In JavaScript this
refers to the element containing the action. For example, if you have a function called hide()
:
function hide(element){
element.style.display = 'none';
}
Calling hide
with this
will hide the element. It returns only the element clicked, even if it is similar to other elements in the DOM.
For example, you may have this
clicking a number in the HTML below will only hide the bullet point clicked.
<ul>
<li class="bullet" onclick="hide(this);">1</li>
<li class="bullet" onclick="hide(this);">2</li>
<li class="bullet" onclick="hide(this);">3</li>
<li class="bullet" onclick="hide(this);">4</li>
</ul>
Only using css techniques this does not seem possible to me. But you could use jqueryui draggable:
$('#drag_me').draggable();
Pickle works good!
import pandas as pd
df.to_pickle('123.pkl') #to save the dataframe, df to 123.pkl
df1 = pd.read_pickle('123.pkl') #to load 123.pkl back to the dataframe df
Extended Chris Pickett's answer because in my case I needed to search deeper than one attribute level:
function findWithAttr(array, attr, value) {
if (attr.indexOf('.') >= 0) {
var split = attr.split('.');
var attr1 = split[0];
var attr2 = split[1];
for(var i = 0; i < array.length; i += 1) {
if(array[i][attr1][attr2] === value) {
return i;
}
}
} else {
for(var i = 0; i < array.length; i += 1) {
if(array[i][attr] === value) {
return i;
}
}
};
};
You can pass 'attr1.attr2' into the function
My selects would not color the background until I added !important to the style.

Create a $scope
function that check it and returns true or false, like a "isEmpty" function and use in your view on ng-if

ng-if="isEmpty(object)"
@@ROWCOUNT will give the number of rows affected by the last SQL statement, it is best to capture it into a local variable following the command in question, as its value will change the next time you look at it:
DECLARE @Rows int
DECLARE @TestTable table (col1 int, col2 int)
INSERT INTO @TestTable (col1, col2) select 1,2 union select 3,4
SELECT @Rows=@@ROWCOUNT
SELECT @Rows AS Rows,@@ROWCOUNT AS [ROWCOUNT]
OUTPUT:
(2 row(s) affected)
Rows ROWCOUNT
----------- -----------
2 1
(1 row(s) affected)
you get Rows
value of 2, the number of inserted rows, but ROWCOUNT is 1 because the SELECT @Rows=@@ROWCOUNT
command affected 1 row
if you have multiple INSERTs or UPDATEs, etc. in your transaction, you need to determine how you would like to "count" what is going on. You could have a separate total for each table, a single grand total value, or something completely different. You'll need to DECLARE a variable for each total you want to track and add to it following each operation that applies to it:
--note there is no error handling here, as this is a simple example
DECLARE @AppleTotal int
DECLARE @PeachTotal int
SELECT @AppleTotal=0,@PeachTotal=0
BEGIN TRANSACTION
INSERT INTO Apple (col1, col2) Select col1,col2 from xyz where ...
SET @AppleTotal=@AppleTotal+@@ROWCOUNT
INSERT INTO Apple (col1, col2) Select col1,col2 from abc where ...
SET @AppleTotal=@AppleTotal+@@ROWCOUNT
INSERT INTO Peach (col1, col2) Select col1,col2 from xyz where ...
SET @PeachTotal=@PeachTotal+@@ROWCOUNT
INSERT INTO Peach (col1, col2) Select col1,col2 from abc where ...
SET @PeachTotal=@PeachTotal+@@ROWCOUNT
COMMIT
SELECT @AppleTotal AS AppleTotal, @PeachTotal AS PeachTotal

You need to set ulimit -c
. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited
and check if everything is correct ulimit -a
. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>
.

The various Office 2003 XML libraries avaliable work pretty well for smaller excel files. However, I find the sheer size of a large workbook saved in the XML format to be a problem. For example, a workbook I work with that would be 40MB in the new (and admittedly more tightly packed) XLSX format becomes a 360MB XML file.
As far as my research has taken me, there are two commercial packages that allow output to the older binary file formats. They are:
Neither are cheap (500USD and 800USD respectively, I think). but both work independant of Excel itself.
What I would be curious about is the Excel output module for the likes of OpenOffice.org. I wonder if they can be ported from Java to .Net.

The main reason you use the default queue over the main queue is to run tasks in the background.
For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
//Background Thread
dispatch_async(dispatch_get_main_queue(), ^(void){
//Run UI Updates
});
});
Just add a >NUL
at the end of the lines producing the messages.
For example,
COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >NUL
well the simplest answer i tried is just remove your code which makes the activity go full screen .I had a code like this which was responsible for making my activity go fullscreen :
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
i just removed my code and it works completely fine although if you want to achieve this with your fullscreen on then you'll have to try some other methods
html2canvas(element[0], {
onrendered: function (canvas) {
pages = Math.ceil(element[0].clientHeight / 1450);
for (i = 0; i <= pages; i += 1) {
if (i > 0) {
pdf.addPage();
}
srcImg = canvas;
sX = 0;
sY = 1450 * i;
sWidth = 1100;
sHeight = 1450;
dX = 0;
dY = 0;
dWidth = 1100;
dHeight = 1450;
window.onePageCanvas = document.createElement("canvas");
onePageCanvas.setAttribute('width', 1100);
onePageCanvas.setAttribute('height', 1450);
ctx = onePageCanvas.getContext('2d');
ctx.drawImage(srcImg, sX, sY, sWidth, sHeight, dX, dY, dWidth, dHeight);
canvasDataURL = onePageCanvas.toDataURL("image/png");
width = onePageCanvas.width;
height = onePageCanvas.clientHeight;
pdf.setPage(i + 1);
pdf.addImage(canvasDataURL, 'PNG', 35, 30, (width * 0.5), (height * 0.5));
}
pdf.save('testfilename.pdf');
}
});
With jQuery 1.6 version you can use the .promise()
method.
$(selector).fadeOut('slow');
$(selector).promise().done(function(){
// will be called when all the animations on the queue finish
});
Use the following code:
if(processing == success) {
header("Location:filename");
exit();
}
And you are good to go.
HTML represents meaning; CSS represents appearance. How you mark up text in a document is not determined by how that text appears on screen, but simply what it means. As another example, some other HTML elements, like headings, are styled font-weight: bold
by default, but they are marked up using <h1>
–<h6>
, not <strong>
or <b>
.
In HTML5, you use <strong>
to indicate important parts of a sentence, for example:
<p><strong>Do not touch.</strong> Contains <strong>hazardous</strong> materials.
And you use <em>
to indicate linguistic stress, for example:
<p>A Gentleman: I suppose he does. But there's no point in asking.
<p>A Lady: Why not?
<p>A Gentleman: Because he doesn't row.
<p>A Lady: He doesn't <em>row</em>?
<p>A Gentleman: No. He <em>doesn't</em> row.
<p>A Lady: Ah. I see what you mean.
These elements are semantic elements that just happen to have bold and italic representations by default, but you can style them however you like. For example, in the <em>
sample above, you could represent stress emphasis in uppercase instead of italics, but the functional purpose of the <em>
element remains the same — to change the context of a sentence by emphasizing specific words or phrases over others:
em {
font-style: normal;
text-transform: uppercase;
}
Note that the original answer (below) applied to HTML standards prior to HTML5, in which <strong>
and <em>
had somewhat different meanings, <b>
and <i>
were purely presentational and had no semantic meaning whatsoever. Like <strong>
and <em>
respectively, they have similar presentational defaults but may be styled differently.
You use <strong>
and <em>
to indicate intense emphasis and normal emphasis respectively.
Or think of it this way: font-weight: bold
is closer to <b>
than <strong>
, and font-style: italic
is closer to <i>
than <em>
. These visual styles are purely visual: tools like screen readers aren't going to understand what bold and italic mean, but some screen readers are able to read <strong>
and <em>
text in a more emphasized tone.
try
{
//Handle the alert pop-up using seithTO alert statement
Alert alert = driver.switchTo().alert();
//Print alert is present
System.out.println("Alert is present");
//get the message which is present on pop-up
String message = alert.getText();
//print the pop-up message
System.out.println(message);
alert.sendKeys("");
//Click on OK button on pop-up
alert.accept();
}
catch (NoAlertPresentException e)
{
//if alert is not present print message
System.out.println("alert is not present");
}
What do you mean by "version number"? It is quite common to tag a commit with a version number and then use
$ git describe --tags
to identify the current HEAD w.r.t. any tags. If you mean you want to know the hash of the current HEAD, you probably want:
$ git rev-parse HEAD
or for the short revision hash:
$ git rev-parse --short HEAD
It is often sufficient to do:
$ cat .git/refs/heads/${branch-master}
but this is not reliable as the ref may be packed.

edit the code for 'select' as below for checking for a 0 or null value selection from select list
case 'select':
var options = $("option:selected", element);
return (options[0].value != 0 && options.length > 0 && options[0].value != '') && (element.type == "select-multiple" || ($.browser.msie && !(options[0].attributes['value'].specified) ? options[0].text : options[0].value).length > 0);
Username you get like this:
var userName = HttpContext.Current.Request.LogonUserIdentity?.Name;
All these suggestions are great, but kind of painful to follow because executing the code to construct the URL or constructing that crazy URL by hand is kind of annoying...
So, I threw together a quick web app to make things easier. Just paste the URL of the extension you want and out comes out the download of your extension already properly named: publisher-extension-version.vsix.

The best way to Load JSON Data into Dictionary is You can user the inbuilt json loader.
Below is the sample snippet that can be used.
import json

data = json.load(f))
f.close()
type(data)
print(data[<keyFromTheJsonFile>])
Check some typo ','

Have you tried using the Developer Mode Extension Patcher on Github?
It automatically patches your Chrome/Chromium/Edge browser and hides the warning.
Depending on devices you might not find sqlite3 command in adb shell. In that case you might want to follow this :
adb shell
$ run-as package.name
$ cd ./databases/
$ ls -l #Find the current permissions - r=4, w=2, x=1
$ chmod 666 ./dbname.db
$ exit
$ exit
adb pull /data/data/package.name/databases/dbname.db ~/Desktop/
adb push ~/Desktop/dbname.db /data/data/package.name/databases/dbname.db
adb shell
$ run-as package.name
$ chmod 660 ./databases/dbname.db #Restore original permissions
$ exit
$ exit
for reference go to https://stackoverflow.com/a/17177091/3758972.
There might be cases when you get "remote object not found" after following above procedure. Then change permission of your database folder to 755 in adb shell.
$ chmod 755 databases/
But please mind that it'll work only on android version < 21.
if you delete something from list , u can use this way : (method sub is case sensitive)
new_list = []
old_list= ["ABCDEFG","HKLMNOP","QRSTUV"]
for data in old_list:
new_list.append(re.sub("AB|M|TV", " ", data))
print(new_list) // output : [' CDEFG', 'HKL NOP', 'QRSTUV']
The absolute easiest way to stream a file into browser using ASP.NET MVC is this:
public ActionResult DownloadFile() {
return File(@"c:\path\to\somefile.pdf", "application/pdf", "Your Filename.pdf");
}
This is easier than the method suggested by @azarc3 since you don't even need to read the bytes.

** Edit **
Apparently my 'answer' is the same as the OP's question. But I am not facing the problem he is having. Probably this was an issue with older version of ASP.NET MVC?
$("#myTable").offset().top;
This will give you the computed offset (relative to document) of any object.
I think the best and safest way to read strings entered by the user is using getline()
Here's an example how to do this:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
char *buffer = NULL;
int read;
unsigned int len;
read = getline(&buffer, &len, stdin);
if (-1 != read)
puts(buffer);
else
printf("No line read...\n");
printf("Size read: %d\n Len: %d\n", read, len);
free(buffer);
return 0;
}
static final
is my preference, I'd only use an enum
if the item was indeed enumerable.
instead of id use title to identify your element and write the code as below.
$(document).ready(()=>{
$("input[title='MyObject']").change(()=>{
console.log("Field has been changed...")
})
});
For portability, one should probably use std::signal
from the standard C++ library, but there is a lot of restriction on what a signal handler can do. Unfortunately, it is not possible to catch a SIGSEGV from within a C++ program without introducing undefined behavior because the specification says:
abort
, exit
, some atomic functions, reinstall current signal handler, memcpy
, memmove
, type traits, `std::move, std::forward
, and some more).throw
expression.This proves that it is impossible to catch SIGSEGV from within a program using strictly standard and portable C++. SIGSEGV is still caught by the operating system and is normally reported to the parent process when a wait family function is called.
You will probably run into the same kind of trouble using POSIX signal because there is a clause that says in 2.4.3 Signal Actions:
The behavior of a process is undefined after it returns normally from a signal-catching function for a SIGBUS, SIGFPE, SIGILL, or SIGSEGV signal that was not generated by
kill()
,sigqueue()
, orraise()
.
A word about the longjump
s. Assuming we are using POSIX signals, using longjump
to simulate stack unwinding won't help:
Although
longjmp()
is an async-signal-safe function, if it is invoked from a signal handler which interrupted a non-async-signal-safe function or equivalent (such as the processing equivalent toexit()
performed after a return from the initial call tomain()
), the behavior of any subsequent call to a non-async-signal-safe function or equivalent is undefined.
This means that the continuation invoked by the call to longjump cannot reliably call usually useful library function such as printf
, malloc
or exit
or return from main without inducing undefined behavior. As such, the continuation can only do a restricted operations and may only exit through some abnormal termination mechanism.
To put things short, catching a SIGSEGV and resuming execution of the program in a portable is probably infeasible without introducing UB. Even if you are working on a Windows platform for which you have access to Structured exception handling, it is worth mentioning that MSDN suggest to never attempt to handle hardware exceptions: Hardware Exceptions.
At last but not least, whether any SIGSEGV would be raised when dereferencing a null valued pointer (or invalid valued pointer) is not a requirement from the standard. Because indirection through a null valued pointer or any invalid valued pointer is an undefined behaviour, which means the compiler assumes your code will never attempt such a thing at runtime, the compiler is free to make code transformation that would elide such undefined behavior. For example, from cppreference,
int foo(int* p) {
int x = *p;
if(!p)
return x; // Either UB above or this branch is never taken
else
return 0;
}
int main() {
int* p = nullptr;
std::cout << foo(p);
}
Here the true path of the if
could be completely elided by the compiler as an optimization; only the else
part could be kept. Said otherwise, the compiler infers foo()
will never receive a null valued pointer at runtime since it would lead to an undefined behaviour. Invoking it with a null valued pointer, you may observe the value 0
printed to standard output and no crash, you may observe a crash with SIGSEG, in fact you could observe anything since no sensible requirements are imposed on programs that are not free of undefined behaviors.
This is a Pythonic way to do it:
import httplib
import yaml
c = httplib.HTTPConnection(address)
c.request('GET', url_path)
r = c.getresponse()
# get the date into a datetime object
lmd = r.getheader('last-modified')
if lmd != None:
cur_data = { url: datetime.strptime(lmd, '%a, %d %b %Y %H:%M:%S %Z') }
else:
print "Hmmm, no last-modified data was returned from the URL."
print "Returned header:"
print yaml.dump(dict(r.getheaders()), default_flow_style=False)
The rest of the script includes an example of archiving a page and checking for changes against the new version, and alerting someone by email.
Try:
javac -cp .;"C:\Users\User Name\Tomcat\apache-tomcat-7.0.108\lib\servlet-api.jar" HelloServlet.java
using windows if there are spaces in your class path.
#include<stdio.h>
int main()
{
char str[100];
scanf("%[^\n]s",str);
printf("%s",str);
return 0;
}
input: read the string
ouput: print the string
This code prints the string with gaps as shown above.
All the above answers are correct. Just providing with your dataset to find perfect divisor:
#include <stdio.h>
int main()
{
int arr[7] = {3,5,7,8,9,17,19};
int j = 51;
int i = 0;
for (i=0 ; i < 7; i++) {
if (j % arr[i] == 0)
printf("%d is the perfect divisor of %d\n", arr[i], j);
}
return 0;
}
Won't simply concatenating the part of your path accomplish what you want?
$ base="/home/user1/MyFolder/"
$ subdir="subFold1"
$ new_path=$base$subdir
$ echo $new_path
/home/user1/MyFolder/subFold1
You can then create the folders/directories as needed.
One convention is to end directory paths with /
(e.g. /home/
) because paths starting with a / could be confused with the root directory. If a double slash (//
) is used in a path, it is also still correct. But, if no slash is used on either variable, it would be incorrect (e.g. /home/user1/MyFoldersubFold1
).
Based on the previous answers, here is another solution which returns the same result as df2.teams.apply(pd.Series) with a much faster run time:
pd.DataFrame([{x: y for x, y in enumerate(item)} for item in df2['teams'].values.tolist()], index=df2.index)
Timings:
In [1]:
import pandas as pd
d1 = {'teams': [['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],
['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG']]}
df2 = pd.DataFrame(d1)
df2 = pd.concat([df2]*1000).reset_index(drop=True)
In [2]: %timeit df2['teams'].apply(pd.Series)
8.27 s ± 2.73 s per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [3]: %timeit pd.DataFrame([{x: y for x, y in enumerate(item)} for item in df2['teams'].values.tolist()], index=df2.index)
35.4 ms ± 5.22 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
This works for me,
DateTimeFormatInfo usDtfi = new CultureInfo("en-US", false).DateTimeFormat;
DateTimeFormatInfo ukDtfi = new CultureInfo("en-GB", false).DateTimeFormat;
string result = Convert.ToDateTime("26/09/2015",ukDtfi).ToString(usDtfi.ShortDatePattern);
axios.get
accepts a request config as the second parameter (not query string params).
You can use the params
config option to set query string params as follows:
axios.get('/api', {
params: {
foo: 'bar'
}
});
You can make a method just like new Date(year,month,date)
in your code by using Calendar
class.
private Date getDate(int year,int month,int date){
Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, year);
cal.set(Calendar.MONTH, month-1);
cal.set(Calendar.DAY_OF_MONTH, day);
return cal.getTime();
}
It will work just like the deprecated constructor of Date
Python3:
import importlib.machinery
loader = importlib.machinery.SourceFileLoader('report', '/full/path/report/other_py_file.py')
handle = loader.load_module('report')
handle.mainFunction(parameter)
This method can be used to import whichever way you want in a folder structure (backwards, forwards doesn't really matter, i use absolute paths just to be sure).
There's also the more normal way of importing a python module in Python3,
import importlib
module = importlib.load_module('folder.filename')
module.function()
Kudos to Sebastian for spplying a similar answer for Python2:
import imp
foo = imp.load_source('module.name', '/path/to/file.py')
foo.MyClass()
Here's a function that I use. Nobody is making use of promisify
and await/async
feature in this post so I thought I would share.
const promisify = require('util').promisify;
const lstat = promisify(require('fs').lstat);
async function isDirectory (path) {
try {
return (await lstat(path)).isDirectory();
}
catch (e) {
return false;
}
}
Note : I don't use require('fs').promises;
because it has been experimental for one year now, better not rely on it.
It's also much easier to manage native builds. Ant and Maven are effectively Java-only. Some plugins exist for Maven that try to handle some native projects, but they don't do an effective job. Ant tasks can be written that compile native projects, but they are too complex and awkward.
We do Java with JNI and lots of other native bits. Gradle simplified our Ant mess considerably. When we started to introduce dependency management to the native projects it was messy. We got Maven to do it, but the equivalent Gradle code was a tiny fraction of what was needed in Maven, and people could read it and understand it without becoming Maven gurus.
Java 8:
int[] intArr = Arrays.stream(integerList).mapToInt(i->i).toArray();
I was getting this error after merging my dev branch to my current branch. I spent sometime to fix the issue. As you can see in the below image, there is no problem in the codes at all.
So the only fix worked for me is that Restarting the VSCode
The easiest way is to use a for loop template tag.
Given the view:
def MyView(request):
...
query_results = YourModel.objects.all()
...
#return a response to your template and add query_results to the context
You can add a snippet like this your template...
<table>
<tr>
<th>Field 1</th>
...
<th>Field N</th>
</tr>
{% for item in query_results %}
<tr>
<td>{{ item.field1 }}</td>
...
<td>{{ item.fieldN }}</td>
</tr>
{% endfor %}
</table>
This is all covered in Part 3 of the Django tutorial. And here's Part 1 if you need to start there.
I normally use the history object for this. It also does not reload the page.
Example:
history.pushState({}, '',

In abstract class, you can write default implementation of methods! But in Interface you can not. Basically, In interface there exist pure virtual methods which have to be implemented by the class which implements the interface.
Etag and Last-modified headers are validators.
They help the browser and/or the cache (reverse proxy) to understand if a file/page, has changed, even if it preserves the same name.
Expires and Cache-control are giving refresh information.
This means that they inform, the browser and the reverse in-between proxies, up to what time or for how long, they may keep the page/file at their cache.
So the question usually is which one validator to use, etag or last-modified, and which refresh infomation header to use, expires or cache-control.
As this is one of the first hits in the search engines, and none of the above seems to work for MongoDB 3.x, here is one regex search that does work:
db.users.find( { 'name' : { '$regex' : yourvalue, '$options' : 'i' } } )
No need to create and extra index or alike.
It just associates a semaphore with every object, and uses that.
Try
string reversed(temp.rbegin(), temp.rend());
EDIT: Elaborating as requested.
string::rbegin()
and string::rend()
, which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator*
to dereference to an element, i.e. a character of the string, and operator++
to advance to the "next" element), such that rbegin()
points to the last character of the string, rend()
points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).
Finally, the constructor we are passing these iterators into is a string constructor of the form:
template <typename Iterator>
string(Iterator first, Iterator last);
which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.
You can use the localeCompare()
method.
string_a.localeCompare(string_b);
/* Expected Returns:
0: exact match
-1: string_a < string_b
1: string_a > string_b
*/
Further Reading:
Almost there. In your predicate, you want a relative path, so change
./book[/author/name = 'John']
to either
./book[author/name = 'John']
or
./book[./author/name = 'John']
and you will match your element. Your current predicate goes back to the root of the document to look for an author
.
See RFC 2822, section 2.1.1 to start.
There are two limits that this standard places on the number of characters in a line. Each line of characters MUST be no more than 998 characters, and SHOULD be no more than 78 characters, excluding the CRLF.
As the RFC states later, you can work around this limit (not that you should) by folding the subject over multiple lines.
Each header field is logically a single line of characters comprising the field name, the colon, and the field body. For convenience however, and to deal with the 998/78 character limitations per line, the field body portion of a header field can be split into a multiple line representation; this is called "folding". The general rule is that wherever this standard allows for folding white space (not simply WSP characters), a CRLF may be inserted before any WSP. For example, the header field:
Subject: This is a test
can be represented as:
Subject: This is a test
The recommendation for no more than 78 characters in the subject header sounds reasonable. No one wants to scroll to see the entire subject line, and something important might get cut off on the right.
Below is the method that worked for me on API 23-25 emulators. The explanation is provided for API 24 but works almost identically for other versions.

Warm advice for readers: please just go over the steps before following them, as some are automated via provided scripts.
In the AVD manager of Android studio (tested on v2.2.3), create a new emulator with the "Android 7.0 (Google APIs)" target:
Download the latest Open GApps package for the emulator's architecture (CPU/ABI). In my case it was x86_64
, but it can be something else depending on your choice of image during the device creation wizard. Interestingly, the architecture seems more important than the correct Android version (i.e. gapps for 6.0 also work on a 7.0 emulator).
Extract the .apk
files using from the following paths (relative to open_gapps-x86_64-7.0-pico-201#####.zip
):
.zip\Core\gmscore-x86_64.tar.lz\gmscore-x86_64\nodpi\priv-app\PrebuiltGmsCore\
.zip\Core\gsfcore-all.tar.lz\gsfcore-all\nodpi\priv-app\GoogleServicesFramework\
.zip\Core\gsflogin-all.tar.lz\gsflogin-all\nodpi\priv-app\GoogleLoginService\
.zip\Core\vending-all.tar.lz\vending-all\nodpi\priv-app\Phonesky\
Note that Open GApps use the Lzip compression, which can be opened using either the tool found on the Lzip website1,2, or on Mac using homebrew: brew install lzip
. Then e.g. lzip -d gmscore-x86_64.tar.lz
.
I'm providing a batch file that utilizes 7z.exe
and lzip.exe
to extract all required .apk
s automatically (on Windows):
@echo off
echo.

To use this, save the script in a file (e.g. unzip_gapps.bat
) and put everything relevant in one folder, as demonstrated below:
Update the su
binary to be able to modify the permissions of the files we will later upload. A new su
binary can be found in the SuperSU by Chainfire package "Recovery flashable" zip
. Get the zip, extract it somewhere, create the a batch file with the following contents in the same folder, and finally run it:
adb root
adb remount
adb push eu.chainfire.supersu_2.78.apk /system/app/
adb push x64/su /system/xbin/su
adb shell chmod 755 /system/xbin/su
adb shell ln -s /system/xbin/su /system/bin/su
adb shell "su --daemon &"
adb shell rm /system/app/SdkSetup.apk
Put all .apk
files in one folder and create a batch file with these contents3:
START /B E:\...\android-sdk\tools\emulator.exe @Nexus_6_API_24 -no-boot-anim -writable-system
adb wait-for-device
adb root
adb shell stop
adb remount
adb push PrebuiltGmsCore.apk /system/priv-app/PrebuiltGmsCore
adb push GoogleServicesFramework.apk /system/priv-app/GoogleServicesFramework
adb push GoogleLoginService.apk /system/priv-app/GoogleLoginService
adb push Phonesky.apk /system/priv-app/Phonesky/Phonesky.apk
adb shell su root "chmod 777 /system/priv-app/**"
adb shell su root "chmod 777 /system/priv-app/PrebuiltGmsCore/*"
adb shell su root "chmod 777 /system/priv-app/GoogleServicesFramework/*"
adb shell su root "chmod 777 /system/priv-app/GoogleLoginService/*"
adb shell su root "chmod 777 /system/priv-app/Phonesky/*"
adb shell start
Notice that the path E:\...\android-sdk\tools\emulator.exe
should be modified according to the location of the Android SDK on your system.
Execute the above batch file (the console should look like this afterwards):

When the emulator loads - close it, delete the Virtual Device and then create another one using the same system image. This fixes the unresponsive Play Store app, "Google Play Services has stopped" and similar problems. It works because in the earlier steps we have actually modified the system image itself (take a look at the Date modified on android-sdk\system-images\android-24\google_apis\x86_64\system.img
). This means that every device created from now on with the system image will have gapps installed!
Start the new AVD. If it takes unusually long to load, close it and instead start it using:
START /B E:\...\android-sdk\tools\emulator.exe @Nexus_6_API_24
adb wait-for-device
adb shell "su --daemon &"
After the AVD starts you will see the image below - notice the Play Store icon in the corner!
3 - I'm not sure all of these commands are needed, and perhaps some of them are overkill... it seems to work - which is what counts. :)
The async is used with a function to makes it into an asynchronous function. The await keyword is used to invoke an asynchronous function synchronously. The await keyword holds the JS engine execution until promise is resolved.
We should use async & await only when we want the result immediately. Maybe the result is being returned from the function or getting used in the next line.

According to http://caniuse.com/#feat=flexbox:
"IE10 and IE11 default values for flex
are 0 0 auto
rather than 0 1 auto
, as per the draft spec, as of September 2013"
So in plain words, if somewhere in your CSS you have something like this: flex:1
, that is not translated the same way in all browsers. Try changing it to 1 0 0
and I believe you will immediately see that it -kinda- works.
The problem is that this solution will probably mess up firefox, but then you can use some hacks to target only Mozilla and change it back:
@-moz-document url-prefix() {
#flexible-content{
flex: 1;
}
}
Since flexbox
is a W3C Candidate and not official, browsers tend to give different results, but I guess that will change in the immediate future.
If someone has a better answer I would like to know!
Sometimes you don't get to design the database, you just have to work with what you are given. In my case it's a database located on a computer that I only have read access to which has been around since 2008.
I need to select from a column in a poorly designed database which is a varchar
with numbers 1-100 but sometimes a random string. I used the following to get around it (although I wish I could have re designed the entire database).
SELECT A from TABLE where isnumeric(A)=1
Another way to check is to inline the function, so that the condition will be checked on every render (every props and state change)
const isDisabled = () =>
// condition check
This works:
<button
type="button"
disabled={this.isDisabled()}
>
Let Me In
</button>
but this will not work:
<button
type="button"
disabled={this.isDisabled}
>
Let Me In
</button>
I would like to provide alternative solution to use package flushbar.
https://github.com/AndreHaueisen/flushbar
As the package said: Use this package if you need more customization when notifying your user. For Android developers, it is made to substitute toasts and snackbars.
Another suggestion to use flushbar How to show snackbar after navigator.pop(context) in Flutter?
You can also set flushbarPosition to TOP or BOTTOM

Just pass it in like any other parameter:

return "a(%s)" % (x,)
def b(f,x):
return f(x)
print b(a,10)
The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.
That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!
<style>
html, body {
height: 100%;
}
#tableContainer-1 {
height: 100%;
width: 100%;
display: table;
}
#tableContainer-2 {
vertical-align: middle;
display: table-cell;
height: 100%;
}
#myTable {
margin: 0 auto;
}
</style>
<div id="tableContainer-1">
<div id="tableContainer-2">
<table id="myTable" border>
<tr><td>Name</td><td>J W BUSH</td></tr>
<tr><td>Proficiency</td><td>PHP</td></tr>
<tr><td>Company</td><td>BLAH BLAH</td></tr>
</table>
</div>
</div>
There is one important question, that is not mentioned anywhere in the above answers, and should drive you to prefer "const" especially for basic types like "int", "string" etc.
Constants can be used as Attribute parameters, static readonly field not!
Azure functions HttpTrigger, not using HttpMethods class in attribute
If only microsoft used constants for Http's GET, POST, DELETE etc.
It would be possible to write
[HttpTrigger(AuthorizationLeve.Anonymous, HttpMethods.Get)] // COMPILE ERROR: static readonly,
But instead I have to resort to
[HttpTrigger(AuthorizationLeve.Anonymous, "GET")] // STRING
Or use my own constant:
public class HttpConstants
{
public const string Get = "GET";
}
[HttpTrigger(AuthorizationLeve.Anonymous, HttpConstants.Get)] // Compile FINE!
Have you tried using the MD5 implementation in hashlib? Note that hashing algorithms typically act on binary data rather than text data, so you may want to be careful about which character encoding is used to convert from text to binary data before hashing.
The result of a hash is also binary data - it looks like Flickr's example has then been converted into text using hex encoding. Use the hexdigest
function in hashlib to get this.
Java's String.format works like so:
if the final destination for this data is a stream (e.g. rendering a webpage or writing to a file), you can assemble the format chunks directly into your stream:
new PrintStream(outputStream, autoFlush, encoding).format("hello {0}", "world");
I speculate that the optimizer will optimize away the format string processing. If so, you're left with equivalent amortized performance to manually unrolling your String.format into a StringBuilder.
#include <iostream>
#include <string.h>
using namespace std;
int main() {
string s="000101";
cout<<s<<"\n";
int a = stoi(s);
cout<<a<<"\n";
s=to_string(a);
s+='1';
cout<<s;
return 0;
}
Output:
A couple ways this can be done:
This will make it a square
ul
{
list-style-type: square;
}
This will make it green
li
{
color: #0F0;
}
This will prevent the text from being green
li p
{
color: #000;
}
However that will require that all text within lists be in paragraphs so that the color is not overridden.
A better way is to make an image of a green square and use:
ul
{
list-style: url(green-square.png);
}
To answer the question without reading too much else into it i would
char str[2] = "\0"; /* gives {\0, \0} */
str[0] = fgetc(fp);
You could use the second line in a loop with what ever other string operations you want to keep using char's as strings.
I can't believe no-one has answered the ops question!
The last set of brackets are used for passing in the parameters to the anonymous function. So, the following example creates a function, then runs it with the x=5 and y=8
(function(x,y){
//code here
})(5,8)
This may seem not so useful, but it has its place. The most common one I have seen is
(function($){
//code here
})(jQuery)
which allows for jQuery to be in compatible mode, but you can refer to it as "$" within the anonymous function.
In the terminal just enter the traditional command:
mongod --version
INSERT
statements that useVALUES
syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.
Example:
INSERT INTO tbl_name
(a,b,c)
VALUES
(1,2,3),
(4,5,6),
(7,8,9);
Insert \u0020 directly in the XML for a blank you would like to preserve.
<string name="spelatonertext3">-4, \u00205, \u0020\u0020-5, \u00206, \u0020-6,</string>
Try Following Code.
var oTable = $('#app-config').dataTable(
{
"bAutoWidth": false,
"bDestroy":true,
"bProcessing" : true,
"bServerSide" : true,
"sPaginationType" : "full_numbers",
"sAjaxSource" : url,
"fnServerData" : function(sSource, aoData, fnCallback) {
alert("sSource"+ sSource);
alert("aoData"+ aoData);
$.ajax({
"dataType" : 'json',
"type" : "GET",
"url" : sSource,
"data" : aoData,
"success" : fnCallback
}).success( function(){ alert("This Function will execute after data table loaded"); });
}
Just use !important
it will help to override
background:none !important;
Although it is said to be a bad practice, !important
can be useful for utility classes, you just need to use it responsibly, check this: When Using important is the right choice
I had a similar problem when I tried to create the React Axios instance.
I resolved it using the below approach.
const instance = axios.create({
baseURL: "https://jsonplaceholder.typicode.com/",
withCredentials: false,
headers: {
'Access-Control-Allow-Origin' : '*',
'Access-Control-Allow-Methods':'GET,PUT,POST,DELETE,PATCH,OPTIONS',
}
});
:e $MYGVIMRC
Enter:set guifont=
Tab Enter.The command in step 6 will insert the contents of the :
special register
which contains the last ex-mode command used. Here that will be the command
from step 4, which has the properly formatted font name thanks to the tab
completion of the value previously set using the GUI dialog.
JavaScript can only close a window that was opened using JavaScript. Example below:
<script>
function myFunction() {
var str = "Sample";
var result = str.link("https://sample.com");
document.getElementById("demo").innerHTML = result;
}
</script>

<div class="device-md d-md-none"></div>
<div class="device-lg d-lg-none"></div>
<div class="device-xl d-xl-none"></div>
<script>
var size = $('.device-xl').is(':hidden') ? 'xl' : ($('.device-lg').is(':hidden') ? 'lg'
: ($('.device-md').is(':hidden') ? 'md': ($('.device-sm').is(':hidden') ? 'sm' : 'xs')));
alert(size);
</script>
If "debugging information" means the values present when exception was raised, then logging.exception(...)
won't help. So you'll need a tool that logs all variable values along with the traceback lines automatically.
Out of the box you'll get log like
2020-03-30 18:24:31 main ERROR File "./temp.py", line 13, in get_ratio
2020-03-30 18:24:31 main ERROR return height / width

Have a look at some pypi tools, I'd name:
Some of them give you pretty crash messages:
But you might find some more on pypi
function redir(data) {_x000D_
document.getElementById('redirect').innerHTML = '<form style="display:none;" position="absolute" method="post" action="location.php"><input id="redirbtn" type="submit" name="value" value=' + data + '></form>';_x000D_

}
_x000D_
<button onclick="redir('dataToBeSent');">Next Page</button>_x000D_

_x000D_
You can use this method which creates a new hidden form whose "data" is sent by "post" to "location.php" when a button[Next Page] is clicked.
if you datatype is datetime of the table.col , then database store data contain two partial : 1 (date) 2 (time)
Just in display data use convert or cast.
Example:
create table #test(part varchar(10),lastTime datetime)
go
insert into #test (part ,lastTime )
values('A','2012-11-05 ')
insert into #test (part ,lastTime )
values('B','2012-11-05 10:30')
go
select * from #test
A 2012-11-05 00:00:00.000
B 2012-11-05 10:30:00.000
select part,CONVERT (varchar,lastTime,111) from #test
A 2012/11/05
B 2012/11/05
select part,CONVERT (varchar(10),lastTime,20) from #test
A 2012-11-05
B 2012-11-05

Let maven generate a batch file to start your application. This is the simplest way to this.
You can use the appassembler-maven-plugin for such purposes.
There is no difference.
Reason:
Books on-line says "
COUNT ( { [ [ ALL | DISTINCT ] expression ] | * } )
"
"1" is a non-null expression: so it's the same as COUNT(*)
.
The optimizer recognizes it for what it is: trivial.
The same as EXISTS (SELECT * ...
or EXISTS (SELECT 1 ...
Example:
SELECT COUNT(1) FROM dbo.tab800krows
SELECT COUNT(1),FKID FROM dbo.tab800krows GROUP BY FKID
SELECT COUNT(*) FROM dbo.tab800krows
SELECT COUNT(*),FKID FROM dbo.tab800krows GROUP BY FKID
Same IO, same plan, the works
Edit, Aug 2011
Edit, Dec 2011
COUNT(*)
is mentioned specifically in ANSI-92 (look for "Scalar expressions 125
")
Case:
a) If COUNT(*) is specified, then the result is the cardinality of T.
That is, the ANSI standard recognizes it as bleeding obvious what you mean. COUNT(1)
has been optimized out by RDBMS vendors because of this superstition. Otherwise it would be evaluated as per ANSI
b) Otherwise, let TX be the single-column table that is the result of applying the <value expression> to each row of T and eliminating null values. If one or more null values are eliminated, then a completion condition is raised: warning-
You would use the Console class
char[] password = console.readPassword("Enter password");
Arrays.fill(password, ' ');
By executing readPassword echoing is disabled. Also after the password is validated it is best to overwrite any values in the array.
If you run this from an ide it will fail, please see this explanation for a thorough answer: Explained
Because I have yet to see an example that works for my use case, here is the most full-proof solution that I was able to realize.

Strangely enough, it doesn't work with display: inline-block
. I suppose that if you need to set the size of any of the dt
elements or dd
elements, you could set the dl
's display as display: flexbox; display: -webkit-flex; display: flex;
and the flex
shorthand of the dd
elements and the dt
elements as something like flex: 1 1 50%
and display
as display: inline-block
. But I haven't tested that, so approach with caution.
you can just do this:
string id = GridName.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString();
Set the CommandText
as well, and call Fill
on the SqlAdapter
to retrieve the results in a DataSet
:
var con = new SqlConnection();
con.ConnectionString = "connection string";
var com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "sp_returnTable";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);
(Example is using parameterless constructors for clarity; can be shortened by using other constructors.)
Unfortunately, there is no cross-browser support for opening a confirmation dialog that is not the default OK/Cancel pair. The solution you provided uses VBScript, which is only available in IE.
I would suggest using a Javascript library that can build a DOM-based dialog instead. Try Jquery UI: http://jqueryui.com/
Converting them to timestamps is the way to go alright, using strtotime, e.g.
$start_date = '2009-06-17';
$end_date = '2009-09-05';
$date_from_user = '2009-08-28';
check_in_range($start_date, $end_date, $date_from_user);
function check_in_range($start_date, $end_date, $date_from_user)
{
// Convert to timestamp
$start_ts = strtotime($start_date);
$end_ts = strtotime($end_date);
$user_ts = strtotime($date_from_user);
// Check that user date is between start & end
return (($user_ts >= $start_ts) && ($user_ts <= $end_ts));
}
The easiest way to generate QR codes with PHP is the phpqrcode library.
You have a constructor which takes 2 parameters. You should write something like:
new ErrorEventArg(errorMsv, lastQuery)
It's less code and easier to read.
EDIT
Or, in order for your way to work, you can try writing a default constructor for ErrorEventArg which would have no parameters, like this:
public ErrorEventArg() {}
I've used XDocument.Root.Add to add elements. Root returns XElement which has an Add function for additional XElements
To run multiple commands just add &&
between two commands like this: command1 && command2
And if you want to run them in two different terminals then you do it like this:
gnome-terminal -e "command1" && gnome-terminal -e "command2"
This will open 2 terminals with command1
and command2
executing in them.
Hope this helps you.
Splice and Slice both are Javascript Array functions.
Splice vs Slice
The splice() method returns the removed item(s) in an array and slice() method returns the selected element(s) in an array, as a new array object.
The splice() method changes the original array and slice() method doesn’t change the original array.
The splice() method can take n number of arguments and slice() method takes 2 arguments.
Splice with Example
Argument 1: Index, Required. An integer that specifies at what position to add /remove items, Use negative values to specify the position from the end of the array.
Argument 2: Optional. The number of items to be removed. If set to 0(zero), no items will be removed. And if not passed, all item(s) from provided index will be removed.
Argument 3…n: Optional. The new item(s) to be added to the array.
var array=[1,2,3,4,5];_x000D_
console.log(array.splice(2));_x000D_
// shows [3, 4, 5], returned removed item(s) as a new array object._x000D_
_x000D_
console.log(array);_x000D_
// shows [1, 2], original array altered._x000D_
_x000D_
var array2=[6,7,8,9,0];_x000D_
console.log(array2.splice(2,1));_x000D_
// shows [8]_x000D_
_x000D_
console.log(array2.splice(2,0));_x000D_
//shows [] , as no item(s) removed._x000D_
_x000D_
console.log(array2);_x000D_
// shows [6,7,9,0]
_x000D_
Slice with Example
Argument 1: Required. An integer that specifies where to start the selection (The first element has an index of 0). Use negative numbers to select from the end of an array.
Argument 2: Optional. An integer that specifies where to end the selection but does not include. If omitted, all elements from the start position and to the end of the array will be selected. Use negative numbers to select from the end of an array.
var array=[1,2,3,4,5]_x000D_
console.log(array.slice(2));_x000D_
// shows [3, 4, 5], returned selected element(s)._x000D_
_x000D_
console.log(array.slice(-2));_x000D_
// shows [4, 5], returned selected element(s)._x000D_
console.log(array);_x000D_
// shows [1, 2, 3, 4, 5], original array remains intact._x000D_
_x000D_
var array2=[6,7,8,9,0];_x000D_
console.log(array2.slice(2,4));_x000D_
// shows [8, 9]_x000D_
_x000D_
console.log(array2.slice(-2,4));_x000D_
// shows [9]_x000D_
_x000D_
console.log(array2.slice(-3,-1));_x000D_
// shows [8, 9]_x000D_
_x000D_
console.log(array2);_x000D_
// shows [6, 7, 8, 9, 0]
_x000D_

The problem I need to solve is to store contracts containing a few fields (address, book, num_of_days, borrower_addr, blk_data), blk_data is a transaction list (block number and transaction address). This question and answer helped me. I would like to share my code as below. Hope this helps.
- Schema definition. See blk_data.
var ContractSchema = new Schema(
{
address: {type: String, required: true, max: 100}, //contract address
// book_id: {type: String, required: true, max: 100}, //book id in the book collection
book: { type: Schema.ObjectId, ref: 'clc_books', required: true }, // Reference to the associated book.
num_of_days: {type: Number, required: true, min: 1},
borrower_addr: {type: String, required: true, max: 100},
// status: {type: String, enum: ['available', 'Created', 'Locked', 'Inactive'], default:'Created'},
blk_data: [{
tx_addr: {type: String, max: 100}, // to do: change to a list
block_number: {type: String, max: 100}, // to do: change to a list
}]
}
);
- Create a record for the collection in the MongoDB. See blk_data.

Just In case: while using the command line to generate the SHA1 fingerprint, be careful while specifying the folder path. If your User Name or android folder path has a space, you should add two double quotes as below:
keytool -list -v -keystore "C:\Users\User Name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
my experience:
in some situations the background image url have to be put separately for all page parts - I use:
var bgImageUrl = "url(../thirdparty/icons/android-circuit.jpg)";
...
$('#indexa').live('pageinit', function() {
$("#indexa").css("background-image",bgImageUrl);
$("#contenta").css("background-image",bgImageUrl);
$("#footera").css("background-image",bgImageUrl);
...
}
where "indexa" is the id of the whole page, and the "contenta" and "footera" are id-s of the content and footer respectively.
This works for sure in PhoneGap + jQuery Mobile
var clickButton = document.getElementById("<%= btnClearSession.ClientID %>");
clickButton.click();
That solution works for me, but remember it wont work if your asp button has
Visible="False"
To hide button that should be triggered with that script you should hide it with <div hidden></div>
Try the following:
POJO pojo = mapper.convertValue(singleObject, POJO.class);
or:
List<POJO> pojos = mapper.convertValue(
listOfObjects,
new TypeReference<List<POJO>>() { });

Launch the program "Run" (Windows Vista/7/8: type it in the start menu search bar) and type:
C:\windows\assembly\GAC_MSIL
Then move to the parent folder (Windows Vista/7/8: by clicking on it in the explorer bar) to see all the GAC files in a normal explorer window. You can now copy, add and remove files as everywhere else.
This can be archived by adding code on the onchange event of the select control.
For Example:
<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="http://gmail.com">Gmail</option>
<option value="http://youtube.com">Youtube</option>
</select>
I assume you are using windows. Open the command prompt and type ipconfig
and find out your local address (on your pc) it should look something like 192.168.1.13
or 192.168.0.5
where the end digit is the one that changes. It should be next to IPv4 Address.
If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13
If you have a virtual host then you will need root to edit the hosts file.
If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.
See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.
Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).
If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow
to allow,deny
in the httpd.conf
file. You can access this by the WAMP menu.
To eliminate possible causes of the issue for now set your config file to
<Directory />
Options FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
<RequireAll>
Require all granted
</RequireAll>
</Directory>
As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.
Config file that fixed the problem:
https://gist.github.com/samvaughton/6790739
Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.
To see all the keyspaces on your Apache Cassandra NoSQL Database Server use the command:
> DESCRIBE KEYSPACES
The definition on Wikipedia reads:
Hence,
sign = lambda x: -1 if x < 0 else (1 if x > 0 else (0 if x == 0 else NaN))
Which for all intents and purposes may be simplified to:
sign = lambda x: -1 if x < 0 else (1 if x > 0 else 0)
This function definition executes fast and yields guaranteed correct results for 0, 0.0, -0.0, -4 and 5 (see comments to other incorrect answers).
Note that zero (0) is neither positive nor negative.
In Visual Studio 2015 this shortcut opens a preview of the definition which even works through typedefs and #defines.
Ctrl + , (comma)
I tried all of above, nothing worked. What resolved the issue was adding IPv6 bindings in the hosts file. In step 5 of @David Murdochs answer, add two lines instead of one, i.e.:
127.0.0.1 dev.example.com
::1 dev.example.com
I figured it out by checking $ ping localhost
from command line, which used to return:
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Instead, it now returns:
Reply from ::1: time<1ms
I don't know why, but for some reason IIS Express started using IPv6 instead of IPv4.
For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.
This answer is detailed at sublime text forum:
http://www.sublimetext.com/forum/viewtopic.php?f=3&p=42052
This answer has links for choosing an appropriate font for your OS,
and gives an answer to an edge case of fonts not lining up.
Another website that lists great monospaced free fonts for programmers. http://hivelogic.com/articles/top-10-programming-fonts
On stackoverflow, see:
Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?
MattDMo's answer here: What is the default font of Sublime Text?
I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)
Other viewing environments that benefit from shorter lines:
github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

Use make_response
of Flask something like
@app.route("/")
def home():
resp = make_response("hello") #here you could use make_response(render_template(...)) too
resp.headers['Access-Control-Allow-Origin'] = '*'
return resp
From flask docs,
flask.make_response(*args)
Sometimes it is necessary to set additional headers in a view. Because views do not have to return response objects but can return a value that is converted into a response object by Flask itself, it becomes tricky to add headers to it. This function can be called instead of using a return and you will get a response object which you can use to attach headers.

I have noticed when using the 2.20.1 version of the maven sunfire plugin, all warnings are written down to a dumpstream file. e.g. /myproject/target/surefire-reports/2017-11-11T23-02-19_850.dumpstream
Tools -> Options -> ReSharper (Tick "Show All setting" if ReSharper option not available ). Then you can do Suspend or Resume. Hope it helps (I tested only in VS2005)
As name itself suggest it reflects what it holds for example class method,etc apart from providing feature to invoke method creating instance dynamically at runtime.
It is used by many frameworks and application under the wood to invoke services without actually knowing the code.
Please change your javascript function as like below....
$(function () {
$("#projectKey").change(function () {
alert($('option:selected').text());

});
You do not need to use $(this)

TextWatcher is a bit verbose for my taste, so I made something a bit easier to swallow:
public abstract class TextValidator implements TextWatcher {
private final TextView textView;
public TextValidator(TextView textView) {
this.textView = textView;
}
public abstract void validate(TextView textView, String text);
@Override
final public void afterTextChanged(Editable s) {
String text = textView.getText().toString();
validate(textView, text);
}
@Override
final public void beforeTextChanged(CharSequence s, int start, int count, int after) { /* Don't care */ }
@Override
final public void onTextChanged(CharSequence s, int start, int before, int count) { /* Don't care */ }
}
Just use it like this:
editText.addTextChangedListener(new TextValidator(editText) {
@Override public void validate(TextView textView, String text) {
/* Validation code here */
}
});
You can now simply do Instant.parse("2015-04-28T14:23:38.521Z")
and get the correct thing now, especially since you should be using Instant
instead of the broken java.util.Date
with the most recent versions of Java.
You should be using DateTimeFormatter
instead of SimpleDateFormatter
as well.
The explanation below is still valid as as what the format represents. But it was written before Java 8 was ubiquitous so it uses the old classes that you should not be using if you are using Java 8 or higher.
Z
as demonstrated:In the pattern the
T
is escaped with'

as documented in the JavaDoc forSimpleDateFormat

is the marker for the oldTimeZone

You can achieve this using different ways but with different performance,
1. Using bracket notation:
var str = "Test";
var lastLetter = str[str.length - 1];
But it's not recommended to use brackets. Check the reasons here
2. charAt[index]:
var lastLetter = str.charAt(str.length - 1)
This is readable and fastest among others. It is most recommended way.
3. substring:
str.substring(str.length - 1);
4. slice:
str.slice(-1);
It's slightly faster than substring.
You can check the performance here
With ES6:
You can use str.endsWith("t");
But it is not supported in IE. Check more details about endsWith here
I think it's most convenient way to inject properties into bean is setter method.
Example:
package org.some.beans;
public class MyBean {
Long id;
String name;
public void setId(Long id) {
this.id = id;
}
public Long getId() {
return id;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
Bean xml definition:
<bean id="Bean1" class="org.some.beans.MyBean">
<property name="id" value="1"/>
<property name="name" value="MyBean"/>
</bean>
For every named property
method setProperty(value)
will be invoked.
This way is especially helpful if you need more than one bean based on one implementation.
For example, if we define one more bean in xml:
<bean id="Bean2" class="org.some.beans.MyBean">
<property name="id" value="2"/>
<property name="name" value="EnotherBean"/>
</bean>
Then code like this:
MyBean b1 = appContext.getBean("Bean1");
System.out.println("Bean id = " + b1.getId() + " name = " + b1.getName());
MyBean b2 = appContext.getBean("Bean2");
System.out.println("Bean id = " + b2.getId() + " name = " + b2.getName());
Will print
Bean id = 1 name = MyBean
Bean id = 2 name = AnotherBean
So, in your case it should look like this:
@Repository("personDao")
public class PersonDaoImpl extends AbstractDaoImpl implements PersonDao {
Long maxResults;
public void setMaxResults(Long maxResults) {
this.maxResults = maxResults;
}
// Now use maxResults value in your code, it will be injected on Bean creation
public void someMethod(Long results) {
if (results < maxResults) {
...
}
}
}
use the include is the easiest way as per

Here are some tools listed in official python website
There is an app called QPython3 in playstore which can be used for both editing and running python script.
Another app called Termux in which you can install python using command
pkg install python
If you want develop apps , there is Python Android Scripting Layer (SL4A) .
The Scripting Layer for Android, SL4A, is an open source application that allows programs written in a range of interpreted languages to run on Android. It also provides a high level API that allows these programs to interact with the Android device, making it easy to do stuff like accessing sensor data, sending an SMS, rendering user interfaces and so on.
You can also check PySide for Android, which is actually Python bindings for the Qt 4.
There's a platform called PyMob where apps can be written purely in Python and the compiler tool-flow (PyMob) converts them in native source codes for various platforms.
Also check python-for-android
python-for-android is an open source build tool to let you package Python code into standalone android APKs. These can be passed around, installed, or uploaded to marketplaces such as the Play Store just like any other Android app. This tool was originally developed for the Kivy cross-platform graphical framework, but now supports multiple bootstraps and can be easily extended to package other types of Python apps for Android.
Try Chaquopy A Python SDK for Android
Anddd... BeeWare
BeeWare allows you to write your app in Python and release it on multiple platforms. No need to rewrite the app in multiple programming languages. It means no issues with build tools, environments, compatibility, etc.
With jQuery (and without FormData API) you can use something like this:
function readFile(file){
var loader = new FileReader();
var def = $.Deferred(), promise = def.promise();
//--- provide classic deferred interface
loader.onload = function (e) { def.resolve(e.target.result); };
loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
loader.onerror = loader.onabort = function (e) { def.reject(e); };
promise.abort = function () { return loader.abort.apply(loader, arguments); };
loader.readAsBinaryString(file);
return promise;
}
function upload(url, data){
var def = $.Deferred(), promise = def.promise();
var mul = buildMultipart(data);
var req = $.ajax({
url: url,
data: mul.data,
processData: false,
type: "post",
async: true,
contentType: "multipart/form-data; boundary="+mul.bound,
xhr: function() {
var xhr = jQuery.ajaxSettings.xhr();
if (xhr.upload) {
xhr.upload.addEventListener('progress', function(event) {
var percent = 0;
var position = event.loaded || event.position; /*event.position is deprecated*/
var total = event.total;
if (event.lengthComputable) {
percent = Math.ceil(position / total * 100);
def.notify(percent);
}
}, false);
}
return xhr;
}
});
req.done(function(){ def.resolve.apply(def, arguments); })
.fail(function(){ def.reject.apply(def, arguments); });
promise.abort = function(){ return req.abort.apply(req, arguments); }
return promise;
}
var buildMultipart = function(data){
var key, crunks = [], bound = false;
while (!bound) {
bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
}
for (var key = 0, l = data.length; key < l; key++){
if (typeof(data[key].value) !== "string") {
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
"Content-Type: application/octet-stream\r\n"+
"Content-Transfer-Encoding: binary\r\n\r\n"+
data[key].value[0]);
}else{
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
data[key].value);
}
}
return {
bound: bound,
data: crunks.join("\r\n")+"\r\n--"+bound+"--"
};
};
//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
var formData = form.find(":input:not('#file')").serializeArray();
formData.file = [fileData, $file[0].files[0].name];
upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});
With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})
The common wisdom that floating-point numbers cannot be compared for equality is inaccurate. Floating-point numbers are no different from integers: If you evaluate "a == b", you will get true if they are identical numbers and false otherwise (with the understanding that two NaNs are of course not identical numbers).
The actual problem is this: If I have done some calculations and am not sure the two numbers I have to compare are exactly correct, then what? This problem is the same for floating-point as it is for integers. If you evaluate the integer expression "7/3*3", it will not compare equal to "7*3/3".
So suppose we asked "How do I compare integers for equality?" in such a situation. There is no single answer; what you should do depends on the specific situation, notably what sort of errors you have and what you want to achieve.
Here are some possible choices.
If you want to get a "true" result if the mathematically exact numbers would be equal, then you might try to use the properties of the calculations you perform to prove that you get the same errors in the two numbers. If that is feasible, and you compare two numbers that result from expressions that would give equal numbers if computed exactly, then you will get "true" from the comparison. Another approach is that you might analyze the properties of the calculations and prove that the error never exceeds a certain amount, perhaps an absolute amount or an amount relative to one of the inputs or one of the outputs. In that case, you can ask whether the two calculated numbers differ by at most that amount, and return "true" if they are within the interval. If you cannot prove an error bound, you might guess and hope for the best. One way of guessing is to evaluate many random samples and see what sort of distribution you get in the results.
Of course, since we only set the requirement that you get "true" if the mathematically exact results are equal, we left open the possibility that you get "true" even if they are unequal. (In fact, we can satisfy the requirement by always returning "true". This makes the calculation simple but is generally undesirable, so I will discuss improving the situation below.)
If you want to get a "false" result if the mathematically exact numbers would be unequal, you need to prove that your evaluation of the numbers yields different numbers if the mathematically exact numbers would be unequal. This may be impossible for practical purposes in many common situations. So let us consider an alternative.
A useful requirement might be that we get a "false" result if the mathematically exact numbers differ by more than a certain amount. For example, perhaps we are going to calculate where a ball thrown in a computer game traveled, and we want to know whether it struck a bat. In this case, we certainly want to get "true" if the ball strikes the bat, and we want to get "false" if the ball is far from the bat, and we can accept an incorrect "true" answer if the ball in a mathematically exact simulation missed the bat but is within a millimeter of hitting the bat. In that case, we need to prove (or guess/estimate) that our calculation of the ball's position and the bat's position have a combined error of at most one millimeter (for all positions of interest). This would allow us to always return "false" if the ball and bat are more than a millimeter apart, to return "true" if they touch, and to return "true" if they are close enough to be acceptable.
So, how you decide what to return when comparing floating-point numbers depends very much on your specific situation.
As to how you go about proving error bounds for calculations, that can be a complicated subject. Any floating-point implementation using the IEEE 754 standard in round-to-nearest mode returns the floating-point number nearest to the exact result for any basic operation (notably multiplication, division, addition, subtraction, square root). (In case of tie, round so the low bit is even.) (Be particularly careful about square root and division; your language implementation might use methods that do not conform to IEEE 754 for those.) Because of this requirement, we know the error in a single result is at most 1/2 of the value of the least significant bit. (If it were more, the rounding would have gone to a different number that is within 1/2 the value.)
Going on from there gets substantially more complicated; the next step is performing an operation where one of the inputs already has some error. For simple expressions, these errors can be followed through the calculations to reach a bound on the final error. In practice, this is only done in a few situations, such as working on a high-quality mathematics library. And, of course, you need precise control over exactly which operations are performed. High-level languages often give the compiler a lot of slack, so you might not know in which order operations are performed.
There is much more that could be (and is) written about this topic, but I have to stop there. In summary, the answer is: There is no library routine for this comparison because there is no single solution that fits most needs that is worth putting into a library routine. (If comparing with a relative or absolute error interval suffices for you, you can do it simply without a library routine.)
It makes it clear that the method accepts null values, and that if you override the method, you should also accept null values.
It also serves as a hint for code analyzers like FindBugs. For example, if such a method dereferences its argument without checking for null first, FindBugs will emit a warning.

You're looking for JSON.stringify()
.
Simple, no jQuery required:
<a href="javascript:clearChecks('group1')">clear</a>
<script type="text/javascript">
function clearChecks(radioName) {
var radio = document.form1[radioName]
for(x=0;x<radio.length;x++) {
document.form1[radioName][x].checked = false
}
}
</script>
while ((line = stringReader.ReadLine()) != null)
{
// split the lines
for (int c = 0; c < line.Length; c++)
{
line = line.Replace("\\", "");
lineBreakOne = line.Substring(1, c - 2);
lineBreakTwo = line.Substring(c + 2, line.Length - 2);
}
}
If you want a true/false value, use this:
$("input:radio[name=theme]").is(":checked")
This method will not truncate a word in the middle.
list($output)=explode("\n",wordwrap(strip_tags($str),500),1);
echo $output. ' ... <a href="#">Read more</a>';
setInterval
or setTimeout
You should pass a reference to a function as the first argument for setTimeout
or setInterval
. This reference may be in the form of:
An anonymous function
setTimeout(function(){/* Look mah! No name! */},2000);
A name of an existing function
function foo(){...}
setTimeout(foo, 2000);
A variable that points to an existing function
var foo = function(){...};
setTimeout(foo, 2000);
Do note that I set "variable in a function" separately from "function name". It's not apparent that variables and function names occupy the same namespace and can clobber each other.
To call a function and pass parameters, you can call the function inside the callback assigned to the timer:
setTimeout(function(){
foo(arg1, arg2, ...argN);
}, 1000);
There is another method to pass in arguments into the handler, however it's not cross-browser compatible.
setTimeout(foo, 2000, arg1, arg2, ...argN);
By default, the context of the callback (the value of this
inside the function called by the timer) when executed is the global object window
. Should you want to change it, use bind
.
setTimeout(function(){
this === YOUR_CONTEXT; // true
}.bind(YOUR_CONTEXT), 2000);
Although it's possible, you should not pass a string to setTimeout
or setInterval
. Passing a string makes setTimeout()
or setInterval()
use a functionality similar to eval()
that executes strings as scripts, making arbitrary and potentially harmful script execution possible.
When you setup WP you (the webserver) may need write access to the files. So the access rights may need to be loose.
chown www-data:www-data -R * # Let Apache be owner
find . -type d -exec chmod 755 {} \; # Change directory permissions rwxr-xr-x
find . -type f -exec chmod 644 {} \; # Change file permissions rw-r--r--
After the setup you should tighten the access rights, according to Hardening WordPress all files except for wp-content should be writable by your user account only. wp-content must be writable by www-data too.
chown <username>:<username> -R * # Let your useraccount be owner
chown www-data:www-data wp-content # Let apache be owner of wp-content
Maybe you want to change the contents in wp-content later on. In this case you could
su
,Whatever you do, make sure the files have rw permissions for www-data.

When you use the start command to a website it will use the default browser by default but if you want to use a specific browser then use start iexplorer.exe www.website.com
Also you cannot have http://
in the url.
To install TF on windows, follow the below-mentioned steps:
conda create --name tensorflow python=3.5
activate tensorflow
conda install jupyter
conda install scipy
pip install tensorflow-gpu
Use pip install tensorflow
in place of pip install tensorflow-gpu
, in case if you want to install CPU only version of TF.
Note: This installation has been tested with Anaconda Python 3.5 (64 bit). I have also tried the same installation steps with (a) Anaconda Python 3.6 (32 bit), (b) Anaconda Python 3.6 (64 bit), and (c) Anaconda Python 3.5 (32 bit), but all of them (i.e. (a), (b) and (c) ) failed.
