May be it will be useful.
The method parameter name should be the same like it has JSON
It will work fine
C#
public ActionResult GetMTypes(int id)
JS
var params = { id: modelId };
var url = '@Url.Action("GetMTypes", "MaintenanceTypes")';
$.ajax({
type: "POST",
url: url,
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify(params),
It will NOT work fine

If you are familiar with gnu getopt, there is a Java port at: http://www.urbanophile.com/arenn/hacking/download.htm.
There appears to be a some classes that do this:
Run the command java -X
and you will get a list of all -X
options:
C:\Users\Admin>java -X
-Xmixed mixed mode execution (default)
-Xint interpreted mode execution only
-Xbootclasspath:<directories and zip/jar files separated by ;>
set search path for bootstrap classes and resources
-Xbootclasspath/a:<directories and zip/jar files separated by ;>
append to end of bootstrap class path
-Xbootclasspath/p:<directories and zip/jar files separated by ;>
prepend in front of bootstrap class path
-Xdiag show additional diagnostic messages
-Xnoclassgc disable class garbage collection
-Xincgc enable incremental garbage collection
-Xloggc:<file> log GC status to a file with time stamps

-Xss<size> set java thread stack size
-Xprof output cpu profiling data
-Xfuture enable strictest checks, anticipating future default
-Xrs reduce use of OS signals by Java/VM (see documentation)
-Xcheck:jni perform additional checks for JNI functions
-Xshare:off do not attempt to use shared class data
-Xshare:auto use shared class data if possible (default)

Since Java passes copies of arguments I feel the relevance of final
is rather limited. I guess the habit comes from the C++ era where you could prohibit reference content from being changed by doing a const char const *
. I feel this kind of stuff makes you believe the developer is inherently stupid as f*** and needs to be protected against truly every character he types. In all humbleness may I say, I write very few bugs even though I omit final
(unless I don't want someone to override my methods and classes). Maybe I'm just an old-school dev.
In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size
like this:
#include <vector>
int main () {
std::vector<int> v;
auto size = v.size();
}
Your third call
int size = v.size();
triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.
int size = static_cast<int>(v.size());
would always compile cleanly and also explicitly states that your conversion from std::vector::size_type
to int
was intended.
Note that if the size of the vector
is greater than the biggest number an int
can represent, size
will contain an implementation defined (de facto garbage) value.

For ubuntu users, this error may arise because setuptool is not installed system-wide. Simply install setuptool using the command:
sudo apt-get install -y python-setuptools
For python3:
sudo apt-get install -y python3-setuptools
After that, install your package again normally, using
sudo python setup.py install
That's all.
It must be because of commit is ahead of your current push.
git pull origin "name of branch you want to push"
git rebase
If git rebase is successful, then good. Otherwise, you have resolve all merge conflicts locally and keep it continuing until rebase with remote is successful.
git rebase --continue
Below method uploads file in a particular folder in a bucket and return the generated url of the file uploaded.

Other than noConflict, this is helpful too:
(function( $ ) {
// Variables and DOM Caching using $.
var body = $('body');
console.log(body);
})( jQuery );
In my case I needed a lower JRE, so I had to tell IntelliJ to use a different one in "Platform Settings"
You can use the jQuery find method
$('select').change(function () {
var optionSelected = $(this).find("option:selected");
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
});
The above solution works perfectly but I choose to add the following code for them willing to get the clicked option. It allows you get the selected option even when this select value has not changed. (Tested with Mozilla only)
$('select').find('option').click(function () {
var optionSelected = $(this);
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
});
Try to understand through this below function using python3
def floating_decimals(f_val, dec):
prc = "{:."+str(dec)+"f}" #first cast decimal as str
print(prc) #str format output is {:.3f}
return prc.format(f_val)
print(floating_decimals(50.54187236456456564, 3))
Output is : 50.542
Hope this helps you!
You can unload a ClassLoader but you cannot unload specific classes. More specifically you cannot unload classes created in a ClassLoader that's not under your control.
If possible, I suggest using your own ClassLoader so you can unload.

This can be achieved using a Spannable String. You will need to import the following
import android.text.SpannableString;
import android.text.style.BackgroundColorSpan;
import android.text.style.StyleSpan;
And then you can change the background of the text using something like the following:
TextView text = (TextView) findViewById(R.id.text_login);
text.setText("");
text.append("Add all your funky text in here");
Spannable sText = (Spannable) text.getText();
sText.setSpan(new BackgroundColorSpan(Color.RED), 1, 4, 0);
Where this will highlight the charecters at pos 1 - 4 with a red color. Hope this helps!
@Tim Down's answer is not performant if you render 2,000 x 2,000 <a>
elements:
OK, I have just thought of a way. Overlay your page with a div that covers the whole document. Inside that, create (say) 2,000 x 2,000 elements (so that the :hover pseudo-class will work in IE 6, see), each 1 pixel in size. Create a CSS :hover rule for those elements that changes a property (let's say font-family). In your load handler, cycle through each of the 4 million elements, checking currentStyle / getComputedStyle() until you find the one with the hover font. Extrapolate back from this element to get the co-ordinates within the document.
N.B. DON'T DO THIS.
But you don't have to render 4 million elements at once, instead use binary search. Just use 4 <a>
elements instead:
<a>
elementsgetComputedStyle()
function determine in which rectangle mouse hoversThis way you would need to repeat these steps max 11 times, considering your screen is not wider than 2048px.
So you will generate max 11 x 4 = 44 <a>
elements.
If you don't need to determine the mouse position exactly to a pixel, but say 10px precision is OK. You would repeat the steps at most 8 times, so you would need to draw max 8 x 4 = 32 <a>
elements.
Also generating and then destroying the <a>
elements is not performat as DOM is generally slow. Instead, you can just reuse the initial 4 <a>
elements and just adjust their top
, left
, width
and height
as you loop through steps.
Now, creating 4 <a>
is an overkill as well. Instead, you can reuse the same one <a>
element for when testing for getComputedStyle()
in each rectangle. So, instead of splitting the search area into 2 x 2 <a>
elements just reuse a single <a>
element by moving it with top
and left
style properties.
So, all you need is a single <a>
element change its width
and height
max 11 times, and change its top
and left
max 44 times and you will have the exact mouse position.
Conroy's answer was right. In the case you need only stuff from body tag, just use:
$('#my_iframe').contents().find('body').html();
What is your opinion to use express-generator it will generate skeleton project to start with, without deprecated messages
appeared in your log
run this command
npm install express-generator -g
Now, create new Express.js starter application by type this command in your Node projects folder
.
express node-express-app
That command tell express to generate new Node.js application with the name node-express-app
.
then Go to the newly created project directory
, install npm packages
and start the app
using the command
cd node-express-app && npm install && npm start
string directoryPath = Path.GetDirectoryName(destinationFileName);
// If directory doesn't exist create one
if (!Directory.Exists(directoryPath))
{
DirectoryInfo di = Directory.CreateDirectory(directoryPath);
}
File.Copy(sourceFileName, destinationFileName);
Try this:
INSERT INTO MyTable1 (Col1, Col2, Col4)
SELECT Col1, Col2, Col3 FROM MyTable2
package-lock.json
is written to when a numerical value in a property such as the "version" property, or a dependency property is changed in package.json
.
If these numerical values in package.json
and package-lock.json
match, package-lock.json
is read from.
If these numerical values in package.json
and package-lock.json
do not match, package-lock.json
is written to with those new values, and new modifiers such as the caret and tilde if they are present. But it is the numeral that is triggering the change to package-lock.json
.
To see what I mean, do the following. Using package.json
without package-lock.json
, run npm install
with:
{
"name": "test",
"version": "1.0.0",
...
"devDependencies": {
"sinon": "7.2.2"
}
}
package-lock.json
will now have:
"sinon": {
"version": "7.2.2",
Now copy/paste both files to a new directory. Change package.json
to (only adding caret):
{
"name": "test",
"version": "1.0.0",
...
"devDependencies": {
"sinon": "^7.2.2"
}
}
run npm install
. If there were no package-lock.json
file, [email protected] would be installed. npm install
is reading from package-lock.json
and installing 7.2.2.
Now change package.json
to:
{
"name": "test",
"version": "1.0.0",
...
"devDependencies": {
"sinon": "^7.3.0"
}
}
run npm install
. package-lock.json
has been written to, and will now show:
"sinon": {
"version": "^7.3.0",
Ok, I know that it's an old issue but I post my answer anyway.
I like this solution. I only have to specify the identity column(s).
SELECT * INTO TempTable FROM MyTable_T WHERE id = 1;
ALTER TABLE TempTable DROP COLUMN id;
INSERT INTO MyTable_T SELECT * FROM TempTable;
DROP TABLE TempTable;
The "id"-column is the identity column and that's the only column I have to specify. It's better than the other way around anyway. :-)
I use SQL Server. You may want to use "CREATE TABLE
" and "UPDATE TABLE
" at row 1 and 2.
Hmm, I saw that I did not really give the answer that he wanted. He wanted to copy the id to another column also. But this solution is nice for making a copy with a new auto-id.
I edit my solution with the idéas from Michael Dibbets.
use MyDatabase;
SELECT * INTO #TempTable FROM [MyTable] WHERE [IndexField] = :id;
ALTER TABLE #TempTable DROP COLUMN [IndexField];
INSERT INTO [MyTable] SELECT * FROM #TempTable;
DROP TABLE #TempTable;
You can drop more than one column by separating them with a ",". The :id should be replaced with the id of the row you want to copy. MyDatabase, MyTable and IndexField should be replaced with your names (of course).
If you want no output at all this is the most simple way:
robocopy src dest > nul
If you still need some information and only want to strip parts of the output, use the parameters from R.Koene's
answer.
After looking more, the root element has to be associated with a schema-namespace as Blaise is noting. Yet, I didnt have a package-info java. So without using the @XMLSchema annotation, I was able to correct this issue by using
@XmlRootElement (name="RetrieveMultipleSetsResponse", namespace = XMLCodeTable.NS1)
@XmlType(name = "ns0", namespace = XMLCodeTable.NS1)
@XmlAccessorType(XmlAccessType.NONE)
public class RetrieveMultipleSetsResponse {//...}
Hope this helps!
I tried this really interesting solution today, which worked for me on an Ubuntu server. Some DNS or another issue in the apt
was making it adamant to not installing some packages from a custom PPA. What I did was install the apt-fast package and use it to install my packages instead of apt
.
apt-fast
is an alternative to apt
which works on top of apt
but uses aria2c
to download packages. It is used to increase the download speed. In my case, it also solved whatever network problem was making apt
to fail.
Using it is exactly the same as apt
:
sudo apt-fast install package-name
Quick note: if you're also using coord_flip()
to flip the x and the y axis, you won't be able to set range limits using coord_cartesian()
because those two functions are exclusive (see here).
Fortunately, this is an easy fix; set your limits within coord_flip()
like so:
p + coord_flip(ylim = c(3,5), xlim = c(100, 400))
This just alters the visible range (i.e. doesn't remove data points).
In order if someone would like to list all tables within specific database without using the "use" keyword:
SELECT TABLE_NAME FROM databasename.INFORMATION_SCHEMA.TABLES
With JUnit 4.12 the following didn't work for me:
java -cp .:/usr/share/java/junit.jar org.junit.runner.JUnitCore [test class name]
Apparently, from JUnit 4.11 onwards you should also include hamcrest-core.jar
in your classpath:
java -cp .:/usr/share/java/junit.jar:/usr/share/java/hamcrest-core.jar org.junit.runner.JUnitCore [test class name]
We put together Web Services on Windows Server and were trying to connect with PHP on Apache. We got the same error. The issue ended up being different versions of the Soap client on the different servers. Matching the SOAP versions in the options on both servers solved the issue in our case.
You are using incorrect overload. You should use this overload
public static MvcHtmlString ActionLink(
this HtmlHelper htmlHelper,
string linkText,
string actionName,
string controllerName,
Object routeValues,
Object htmlAttributes
)
And the correct code would be
<%= Html.ActionLink("Create New Part", "CreateParts", "PartList", new { parentPartId = 0 }, null)%>
Note that extra parameter at the end.
For the other overloads, visit LinkExtensions.ActionLink Method. As you can see there is no string, string, string, object
overload that you are trying to use.
Old question ... nonetheless, just add a checkbox somewhere in the sheet. Checking or unchecking it will refresh the cell formulae.
If anyone's still looking for a solution to this, I found an answer at How to play ringtone/alarm sound in Android
try {
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
r.play();
} catch (Exception e) {
e.printStackTrace();
}
You can change TYPE_NOTIFICATION to TYPE_ALARM, but you'll want to keep track of your Ringtone r in order to stop playing it... say, when the user clicks a button or something.
In my case, there was no string on which i was calling appendChild
, the object i was passing on appendChild
argument was wrong, it was an array and i had pass an element object, so i used divel.appendChild(childel[0])
instead of divel.appendChild(childel)
and it worked. Hope it help someone.
A few things here...
If you want to call a function when the onclick event happens, you'll just want the function name plus the parameters.
Then if your parameters are a variable (which they look like they are), then you won't want quotes around them. Not only that, but if these are global variables, you'll want to add in "window." before that, because that's the object that holds all global variables.
Lastly, if these parameters aren't variables, you'll want to exclude the slashes to escape those characters. Since the value of onclick is wrapped by double quotes, single quotes won't be an issue. So your answer will look like this...
<a href=# onclick="ReAssign('valuationId', window.user)">Re-Assign</a>
There are a few extra things to note here, if you want more than a quick solution.
You looked like you were trying to use the + operator to combine strings in HTML. HTML is a scripting language, so when you're writing it, the whole thing is just a string itself. You can just skip these from now on, because it's not code your browser will be running (just a whole bunch of stuff, and anything that already exists is what has special meaning by the browser).
Next, you're using an anchor tag/link that doesn't actually take the user to another website, just runs some code. I'd use something else other than an anchor tag, with the appropriate CSS to format it to look the way you want. It really depends on the setting, but in many cases, a span tag will do. Give it a class (like class="runjs") and have a rule of CSS for that. To get it to imitate a link's behavior, use this:
.runjs {
cursor: pointer;
text-decoration: underline;
color: blue;
}
This lets you leave out the href attribute which you weren't using anyways.
Last, you probably want to use JavaScript to set the value of this link's onclick attribute instead of hand writing it. It keeps your page cleaner by keeping the code of your page separate from what the structure of your page. In your class, you could change all these links like this...
var links = document.getElementsByClassName('runjs');
for(var i = 0; i < links.length; i++)
links[i].onclick = function() { ReAssign('valuationId', window.user); };
While this won't work in some older browsers (because of the getElementsByClassName method), it's just three lines and does exactly what you're looking for. Each of these links has an anonymous function tied to them meaning they don't have any variable tied to them except that tag's onclick value. Plus if you wanted to, you could include more lines of code this way, all grouped up in one tidy location.
You might be in formula view:
Hit Ctrl + ` to switch
Not so hard:
#include <thread>
void Test::runMultiThread()
{
std::thread t1(&Test::calculate, this, 0, 10);
std::thread t2(&Test::calculate, this, 11, 20);
t1.join();
t2.join();
}
If the result of the computation is still needed, use a future instead:
#include <future>
void Test::runMultiThread()
{
auto f1 = std::async(&Test::calculate, this, 0, 10);
auto f2 = std::async(&Test::calculate, this, 11, 20);
auto res1 = f1.get();
auto res2 = f2.get();
}
Make sure the 'li' doesn't have overflow: hidden
applied.
I was having troubles understanding an applying the accepted answer. I needed a little more context. Now that I have figured it out, here is a full example:

// initialize as invisible (could also do in xml)
myView.setVisibility(View.INVISIBLE);
myButton.setText("Slide up");
isUp = false;
}
// slide the view from below itself to the current position
public void slideUp(View view){
view.setVisibility(View.VISIBLE);
TranslateAnimation animate = new TranslateAnimation(
0, // fromXDelta
0, // toXDelta
view.getHeight(), // fromYDelta

animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
}
// slide the view from its current position to below itself
public void slideDown(View view){
TranslateAnimation animate = new TranslateAnimation(
0, // fromXDelta
0, // toXDelta

animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
}
public void onSlideViewButtonClick(View view) {
if (isUp) {
slideDown(myView);

myButton.setText("Slide down");
}

ASP.NET does not search bin/debug
or any subfolder under bin for assemblies like other types of applications do. You can instruct the runtime to look in a different place using the following configuration:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="bin;bin\Debug;bin\Release"/>
</assemblyBinding>
</runtime>
</configuration>
Another solution is to add a hidden input field to the php page:
<input type="hidden" id="myHiddenLocationHash" name="myHiddenLocationHash" value="">
Using javascript/jQuery you can set the value of this field on the page load or responding to an event :
$('#myHiddenLocationHash').val(document.location.hash.replace('#',''));
In php on the server side you can read this value using the $_POST collection:
$server_location_hash = $_POST['myHiddenLocationHash'];
I'm answering on specific to this error code(08s01).
usually, MySql close socket connections are some interval of time that is wait_timeout defined on MySQL server-side which by default is 8hours. so if a connection will timeout after this time and the socket will throw an exception which SQLState is "08s01".
1.use connection pool to execute Query, make sure the pool class has a function to make an inspection of the connection members before it goes time_out.
2.give a value of <wait_timeout> greater than the default, but the largest value is 24 days
3.use another parameter in your connection URL, but this method is not recommended, and maybe deprecated.
For existing matches, use query
:
df.query(' A > 3' ).head(1)
Out[33]:
A B C
2 4 6 3
df.query(' A > 4 and B > 3' ).head(1)
Out[34]:
A B C
4 5 4 5
df.query(' A > 3 and (B > 3 or C > 2)' ).head(1)
Out[35]:

Just open the url. Facebook automatically registers for deep links.
let url = URL(string:"https://www.facebook.com/TheGoodLordAbove")!
UIApplication.shared.open(url,completionHandler:nil)
this opens in the facebook app if installed, and in your default browser otherwise
here is what works with the version of the program that I'm using: may work for you too.
I will just place the instruction and command that does it. class is the name of the table. you change it in the table its self with this method. not just the return on the search process.
view the table class
select * from class
change the length of the columns FacID (seen as "faci") and classnumber (seen as "classnu") to fit the whole labels.
alter table class modify facid varchar (5);
alter table class modify classnumber varchar(11);
view table again to see the difference
select * from class;
(run the command again to see the difference)
This changes the the actual table for good, but for better.
P.S. I made these instructions up as a note for the commands. This is not a test, but can help on one :)
You are missing the directive that states the connection uses SSL
require ("class.phpmailer.php");
$mail = new PHPMailer();

$mail->Password = "YAHOO ACCOUNT PASSWORD"; // SMTP password
$mail->SMTPSecure = "ssl";
$mail->Host = "YAHOO HOST"; // SMTP host
$mail->Port = 465;
Then add in the other parts
$webmaster_email = "[email protected]"; //Reply to this email ID
$email="[email protected]"; // Recipients email ID
$name="My Name"; // Recipient's name
$mail->From = $webmaster_email;
$mail->FromName = "My Name";
$mail->AddAddress($email,$name);
$mail->AddReplyTo($webmaster_email,"My Name");

$mail->IsHTML(true); // send as HTML
$mail->Subject = "subject";
$mail->Body = "Hi,

}
As a side note, I have had trouble using Body + AltBody together although they are supposed to work. As a result, I wrote the following wrapper function which works perfectly.

Enclose your code with the html and body tags. Size attribute does not correspond to font-size and it looks like its domain does not go beyond value 7. Furthermore font tag is not supported in HTML5. Consider this code for your case
<!DOCTYPE html>
<html>
<body>
<font size="2" face="Courier New" >
<table width="100%">
<tr>
<td><b>Client</b></td>
<td><b>InstanceName</b></td>
<td><b>dbname</b></td>
<td><b>Filename</b></td>
<td><b>KeyName</b></td>
<td><b>Rotation</b></td>
<td><b>Path</b></td>
</tr>
<tr>
<td>NEWDEV6</td>
<td>EXPRESS2012</td>
<td>master</td><td>master.mdf</td>
<td>test_key_16</td><td>0</td>
<td>d:\Program Files\Microsoft SQL Server\MSSQL11.EXPRESS2012\MSSQL\DATA\master.mdf</td>

if you need a fallback function you could use this
function session_register($name){
global $$name;
$_SESSION[$name] = $$name;
$$name = &$_SESSION[$name];
}
If you are looking for a range of columns, you can try this:
df.iloc[7:] = df.iloc[7:].astype(float)
The examples above will convert type to be float, for all the columns begin with the 7th to the end. You of course can use different type or different range.
I think this is useful when you have a big range of columns to convert and a lot of rows. It doesn't make you go over each row by yourself - I believe numpy do it more efficiently.
This is useful only if you know that all the required columns contain numbers only - it will not change "bad values" (like string) to be NaN for you.
Your code should be something like
require_once('class.twitter.php');
$t = new twitter;
$t->username = 'user';
$t->password = 'password';
$data = $t->publicTimeline();
Unfortunately there's no min
(or max
)-background-size in CSS you can only use
background-size
. However if you are seeking a responsive background image you can use Vmin
and Vmax
units for the background-size
property to achieve something similar.
#one {
background:url('../img/blahblah.jpg') no-repeat;
background-size:10vmin 100%;
}
that will set the height to 10% of the whichever smaller viewport you have whether vertical or horizontal, and will set the width to 100%.
Read more about css units here: https://www.w3schools.com/cssref/css_units.asp
// define
var foo = {
bar: ['foo', 'bar', 'baz']
};
// access
foo.bar[2]; // will give you 'baz'
with Apache PDFBox it goes like this:
PDDocument document = PDDocument.load(new File("test.pdf"));
if (!document.isEncrypted()) {
PDFTextStripper stripper = new PDFTextStripper();
String text = stripper.getText(document);
System.out.println("Text:" + text);
}
document.close();
You can't remove hidden without also removing system.
You want:
cd mydir
attrib -H -S /D /S
That will remove the hidden and system attributes from all the files/folders inside of your current directory.
Mine Solution was just to add below style.
<div class="modal-body" style="clear: both;overflow: hidden;">
You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?
if (query.list().size() == 1)
Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.
Thanks for this post. It helped me a great deal. In my case I am also editing the text in a separate view controller. I noticed that when I use:
[cell.contentView addSubview:cellLabel];
in the tableView:cellForRowAtIndexPath: method that the label view was continually rendered over the top of the previous view each time I edited the cell. The text became pixelated, and when something was deleted or changed, the previous version was visible under the new version. Here's how I solved the problem:
if ([[cell.contentView subviews] count] > 0) {
UIView *test = [[cell.contentView subviews] objectAtIndex:0];
[test removeFromSuperview];
}
[cell.contentView insertSubview:cellLabel atIndex:0];
No more weird layering. If there is a better way to handle this, Please let me know.
First register a receiver in your manifest.xml file:
<receiver android:name="com.mileagelog.service.Broadcast_PowerUp" >
<intent-filter>
<action android:name="android.intent.action.ACTION_POWER_CONNECTED" />
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED" />
</intent-filter>
</receiver>
and then write a broadcast for this receiver like:
public class Broadcast_PowerUp extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_POWER_CONNECTED)) {
Toast.makeText(context, "Service_PowerUp Started",
Toast.LENGTH_LONG).show();
} else if (action.equals(Intent.ACTION_POWER_DISCONNECTED)) {
Toast.makeText(context, "Service_PowerUp Stoped", Toast.LENGTH_LONG)
.show();
}
}
}
From axios docs you have baseURL and url
baseURL
will be prepended to url
when making requests. So you can define baseURL
as http://127.0.0.1:8000
and make your requests to /url
// `url` is the server URL that will be used for the request url: '/user', // `baseURL` will be prepended to `url` unless `url` is absolute. // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs // to methods of that instance. baseURL: 'https://some-domain.com/api/',
The simplest way is to use the JsonPrimitive
class, which derives from JsonElement
, as shown below:
JsonElement element = new JsonPrimitive(yourString);
JsonObject result = element.getAsJsonObject();
I also had added on or extended additional columns into my AspNetUsers table. When I wanted to simply view this data I found many examples like the code above with "Extensions" etc... This really amazed me that you had to write all those lines of code just to get a couple values from the current users.
It turns out that you can query the AspNetUsers table like any other table:
ApplicationDbContext db = new ApplicationDbContext();
var user = db.Users.Where(x => x.UserName == User.Identity.Name).FirstOrDefault();
The proper way to do this is to use multiple tables and JOIN
them in your queries.
For example:
CREATE TABLE person (
`id` INT NOT NULL PRIMARY KEY,
`name` VARCHAR(50)
);
CREATE TABLE fruits (
`fruit_name` VARCHAR(20) NOT NULL PRIMARY KEY,
`color` VARCHAR(20),
`price` INT
);
CREATE TABLE person_fruit (
`person_id` INT NOT NULL,
`fruit_name` VARCHAR(20) NOT NULL,
PRIMARY KEY(`person_id`, `fruit_name`)
);
The person_fruit
table contains one row for each fruit a person is associated with and effectively links the person
and fruits
tables together, I.E.
1 | "banana"
1 | "apple"
1 | "orange"
2 | "straberry"
2 | "banana"
2 | "apple"
When you want to retrieve a person and all of their fruit you can do something like this:
SELECT p.*, f.*
FROM person p
INNER JOIN person_fruit pf
ON pf.person_id = p.id
INNER JOIN fruits f
ON f.fruit_name = pf.fruit_name
In C++, there is only a subtle difference. It's a holdover from C, in which it makes a difference.
The C language standard (C89 §3.1.2.3, C99 §6.2.3, and C11 §6.2.3) mandates separate namespaces for different categories of identifiers, including tag identifiers (for struct
/union
/enum
) and ordinary identifiers (for typedef
and other identifiers).
If you just said:
struct Foo { ... };
Foo x;
you would get a compiler error, because Foo
is only defined in the tag namespace.
You'd have to declare it as:
struct Foo x;
Any time you want to refer to a Foo
, you'd always have to call it a struct Foo
. This gets annoying fast, so you can add a typedef
:
struct Foo { ... };
typedef struct Foo Foo;
Now struct Foo
(in the tag namespace) and just plain Foo
(in the ordinary identifier namespace) both refer to the same thing, and you can freely declare objects of type Foo
without the struct
keyword.
The construct:
typedef struct Foo { ... } Foo;
is just an abbreviation for the declaration and typedef
.
Finally,
typedef struct { ... } Foo;
declares an anonymous structure and creates a typedef
for it. Thus, with this construct, it doesn't have a name in the tag namespace, only a name in the typedef namespace. This means it also cannot be forward-declared. If you want to make a forward declaration, you have to give it a name in the tag namespace.
In C++, all struct
/union
/enum
/class
declarations act like they are implicitly typedef
'ed, as long as the name is not hidden by another declaration with the same name. See Michael Burr's answer for the full details.
The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function.
Use
Z=XY[0]+XY[1]
Instead of
Z=XY(i,0)+XY(i,1)
Use <code>
for inline code that can wrap and <pre><code>
for block code that must not wrap. <samp>
is for sample output, so I would avoid using it to represent sample code (which the reader is to input). This is what Stack Overflow does.
(Better yet, if you want easy to maintain, let the users edit the articles as Markdown, then they don’t have to remember to use <pre><code>
.)
HTML5 agrees with this in “the pre
element”:
The pre element represents a block of preformatted text, in which structure is represented by typographic conventions rather than by elements.
Some examples of cases where the pre element could be used:
- Including fragments of computer code, with structure indicated according to the conventions of that language.
[…]
To represent a block of computer code, the pre element can be used with a code element; to represent a block of computer output the pre element can be used with a samp element. Similarly, the kbd element can be used within a pre element to indicate text that the user is to enter.
In the following snippet, a sample of computer code is presented.
<p>This is the <code>Panel</code> constructor:</p>
<pre><code>function Panel(element, canClose, closeHandler) {
this.element = element;
this.canClose = canClose;
this.closeHandler = function () { if (closeHandler) closeHandler() };
}</code></pre>

onCreate(Bundle savedInstanceState) gets called and savedInstanceState will be non-null if your Activity and it was terminated in a scenario(visual view) described above. Your app can then grab (catch) the data from savedInstanceState and regenerate your Activity
[+]is simpler
String s = "ddjdjdj+kfkfkf";
if(s.contains ("+"))
{
String parts[] = s.split("[+]");
s = parts[0]; // i want to strip part after +
}
System.out.println(s);
ReducedForm
is a type, so you cannot say
ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
You can only use the .
operator on an instance:
ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
And if you need to extract several properties from each object, then
let newArr = _.map(arr, o => _.pick(o, ['name', 'surname', 'rate']));
on document ready event there is no a tag with class tabclick. so you have to bind click event dynamically when you are adding tabclick class. please this code:
$("a.applicationdata").click(function() {
var appid = $(this).attr("id");
$('#gentab a').addClass("tabclick")
.click(function() {
var liId = $(this).parent("li").attr("id");
alert(liId);
});
$('#gentab a').attr('href', '#datacollector');
});
Reviving an old question, but I think a really good way to think of this is in terms of the API that you are defining.
public
- Everything marked public is part of the API that anyone using your class/interface/other will use and rely on.
protected
- Don't be fooled, this is also part of the API! People can subclass, extend your code and use anything marked protected.
private
- Private properties and methods can be changed as much as you like. No one else can use these. These are the only things you can change without making breaking changes.
Or in Semver terms:
Changes to anything public
or protected
should be considered MAJOR changes.
Anything new public
or protected
should be (at least) MINOR
Only new/changes to anything private
can be PATCH
So in terms of maintaining code, its good to be careful about what things you make public
or protected
because these are the things you are promising to your users.
The JSON spec says you CAN escape forward slash, but you don't have to.
You will want to verify whatever your calling is valid. For example, in the case of a specific function, you will want to check and see if the function exists:
function doIt($callback) {
if(function_exists($callback)) {
$callback();
} else {
// some error handling
}
}
I also don't under stand what the "-" means after the 200 140 section of the log
That value corresponds to the referer as described by Joachim. If you see a dash though, that means that there was no referer value to begin with (eg. the user went straight to a specific destination, like if he/she typed a URL in their browser)
To remove
ALL event-handlers
, this is what worked for me:
To remove all event handlers mean to have the plain HTML structure
without all the event handlers
attached to the element
and its child nodes
. To do this, jQuery's clone()
helped.
var original, clone;
// element with id my-div and its child nodes have some event-handlers
original = $('#my-div');
clone = original.clone();
//
original.replaceWith(clone);
With this, we'll have the clone
in place of the original
with no event-handlers
on it.
Good Luck...
You need to change project settings. Right click your project, go to properites. In Application tab change output type to class library instead of Windows application.
Use FileInfo.Exists
Property:
DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles("*.xml");
if (TXTFiles.Length == 0)
{
log.Info("no files present")
}
foreach (var fi in TXTFiles)
log.Info(fi.Exists);
or File.Exists
Method:
string curFile = @"c:\temp\test.txt";
Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");
Even if both work, I would use the latter.
location
is an object, and assigning a string to an object doesn't bode well for readability or maintenance.
NOTE!!! for Docker Compose Usage:
Since Docker Compose creates an isolated network for each cluster, the methods below do not work with docker-compose
.
The most elegant and easy way is defining a shell function, currently the most-voted answer @WouterD's:
dockip() {
docker inspect --format '{{ .NetworkSettings.IPAddress }}' "$@"
}
Docker can write container IDs to a file like Linux programs:
Running with --cidfile=filename
, Docker dumps the ID of the container to "filename".
See "Docker runs PID equivalent Section" for more information.
--cidfile="app.cid": Write the container ID to the file
Using a PID file:
Running container with --cidfile
parameter, the app.cid
file content is like:
a29ac3b9f8aebf66a1ba5989186bd620ea66f1740e9fe6524351e7ace139b909
You can use file content to inspect Docker containers:
blog-v4 git:(develop) ? docker inspect `cat app.cid`
You can extract the container IP using an inline Python script:
$ docker inspect `cat app.cid` | python -c "import json;import sys;\
sys.stdout.write(json.load(sys.stdin)[0]['NetworkSettings']['IPAddress'])"
172.17.0.2
Here's a more human friendly form:
#!/usr/bin/env python
# Coding: utf-8
# Save this file like get-docker-ip.py in a folder that in $PATH
# Run it with
# $ docker inspect <CONTAINER ID> | get-docker-ip.py
import json
import sys
sys.stdout.write(json.load(sys.stdin)[0]['NetworkSettings']['IPAddress'])
See "10 alternatives of getting the Docker container IP addresses" for more information.
It should be a Python expression that, when eval'd, creates an object with the exact same properties as this one. For example, if you have a Fraction
class that contains two integers, a numerator and denominator, your __repr__()
method would look like this:
# in the definition of Fraction class
def __repr__(self):
return "Fraction(%d, %d)" % (self.numerator, self.denominator)
Assuming that the constructor takes those two values.
Here is an example
import numpy as np
import matplotlib.pyplot as plt
x = np.random.rand(100)
y = np.random.rand(100)
t = np.arange(100)
plt.scatter(x, y, c=t)
plt.show()
Here you are setting the color based on the index, t
, which is just an array of [1, 2, ..., 100]
.
Perhaps an easier-to-understand example is the slightly simpler
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(100)
y = x
t = x
plt.scatter(x, y, c=t)
plt.show()
Note that the array you pass as c
doesn't need to have any particular order or type, i.e. it doesn't need to be sorted or integers as in these examples. The plotting routine will scale the colormap such that the minimum/maximum values in c
correspond to the bottom/top of the colormap.
You can change the colormap by adding
import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.cmap_name)
Importing matplotlib.cm
is optional as you can call colormaps as cmap="cmap_name"
just as well. There is a reference page of colormaps showing what each looks like. Also know that you can reverse a colormap by simply calling it as cmap_name_r
. So either
plt.scatter(x, y, c=t, cmap=cm.cmap_name_r)
# or
plt.scatter(x, y, c=t, cmap="cmap_name_r")
will work. Examples are "jet_r"
or cm.plasma_r
. Here's an example with the new 1.5 colormap viridis:
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(100)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')
plt.show()
You can add a colorbar by using
plt.scatter(x, y, c=t, cmap='viridis')
plt.colorbar()
plt.show()
Note that if you are using figures and subplots explicitly (e.g. fig, ax = plt.subplots()
or ax = fig.add_subplot(111)
), adding a colorbar can be a bit more involved. Good examples can be found here for a single subplot colorbar and here for 2 subplots 1 colorbar.
sudo killall -9 "process name"
The ENOSPC
("No space left on device") error will be triggered in any situation in which the data or the metadata associated with an I/O operation can't be written down anywhere because of lack of space. This doesn't always mean disk space – it could mean physical disk space, logical space (e.g. maximum file length), space in a certain data structure or address space. For example you can get it if there isn't space in the directory table (vfat) or there aren't any inodes left. It roughly means “I can't find where to write this down”.
Particularly in Python, this can happen on any write I/O operation. It can happen during f.write
, but it can also happen on open
, on f.flush
and even on f.close
. Where it happened provides a vital clue for the reason that it did – if it happened on open
there wasn't enough space to write the metadata for the entry, if it happened during f.write
, f.flush
or f.close
there wasn't enough disk space left or you've exceeded the maximum file size.
If the filesystem in the given directory is vfat
you'd hit the maximum file limit at about the same time that you did. The limit is supposed to be 2^16 directory entries, but if I recall correctly some other factors can affect it (e.g. some files require more than one entry).
It would be best to avoid creating so many files in a directory. Few filesystems handle so many directory entries with ease. Unless you're certain that your filesystem deals well with many files in a directory, you can consider another strategy (e.g. create more directories).
P.S. Also do not trust the remaining disk space – some file systems reserve some space for root and others miscalculate the free space and give you a number that just isn't true.
The jQuery API documentation lists live()
as deprecated as of version 1.7 and removed as of version 1.9: link.
version deprecated: 1.7, removed: 1.9
Furthermore it states:
As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live()
There are three options, that you can use. -I
is to exclude binary files in grep. Other are for line numbers and file names.
grep -I -n -H
-I -- process a binary file as if it did not contain matching data;
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match
So this might be a way to run grep:
grep -InH your-word *
Note: This code is untested
Define a record for your refCursor return type, call it rec. For example:
TYPE MyRec IS RECORD (col1 VARCHAR2(10), col2 VARCHAR2(20), ...); --define the record
rec MyRec; -- instantiate the record
Once you have the refcursor returned from your procedure, you can add the following code where your comments are now:
LOOP
FETCH refCursor INTO rec;
EXIT WHEN refCursor%NOTFOUND;
dbms_output.put_line(rec.col1||','||rec.col2||','||...);
END LOOP;
Define 'better'. A synchronized block is only better because it allows you to:
Now your specific example is an example of the double-checked locking pattern which is suspect (in older Java versions it was broken, and it is easy to do it wrong).
If your initialization is cheap, it might be better to initialize immediately with a final field, and not on the first request, it would also remove the need for synchronization.
My case was like this
Strangely, I noticed that the php.ini file that WAMP was using wasn't the one in the php directory, but rather was referencing a php.ini file in the bin directory... I copied my php.ini file to wamp\bin\apache\apache2.4.17\bin directory, restarted the wamp services and PHPMyadmin was off and running...
Thanks I solved the problem
One of the rules you have to know is that the table column you want to reference to has to be with the same data type as The referencing table . 2 if you decide to use mysql you have to use InnoDB Engine because according to your question that’s the engine which supports what you want to achieve in mysql .
Bellow is the code try it though the first people to answer this question they 100% provided great answers and please consider them all .

The default for an enum
(in fact, any value type) is 0 -- even if that is not a valid value for that enum
. It cannot be changed.
Google says SHA256 is available to PHP.
You should definitely use a salt. I'd recommend using random bytes (and not restrict yourself to characters and numbers). As usually, the longer you choose, the safer, slower it gets. 64 bytes ought to be fine, i guess.
Python is an interesting language in that while there is usually one (or two) "obvious" ways to accomplish any given task, flexibility still exists.
s = "string"
i = 0
print (s + repr(i))
The above code snippet is written in Python3 syntax but the parentheses after print were always allowed (optional) until version 3 made them mandatory.
Hope this helps.

just edit wp_user table with your phpmyadmin, and choose MD5 on Function field then input your new password, save it (go button).
mysqldump --extended-insert=FALSE
Be aware that multiple inserts will be slower than one big insert.
What you are trying to do is an extension of string slicing in Python:
Say all strings are of length 10, last char to be removed:
>>> st[:9]
'abcdefghi'
To remove last N
characters:
>>> N = 3
>>> st[:-N]
'abcdefg'
If you prefer binding your events outside the html-markup (in the javascript) you could do it like this:

function(event) {_x000D_
if (event.target.value === "Open Curtain") {_x000D_
event.target.value = "Close Curtain";_x000D_
} else {_x000D_
event.target.value = "Open Curtain";_x000D_
}_x000D_
},_x000D_
false_x000D_
);

You can use set
with the /p
argument:
SET /P variable=[promptString]
The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.
So, simply use something like
set /p Input=Enter some text:
Later you can use that variable as argument to a command:
myCommand %Input%
Be careful though, that if your input might contain spaces it's probably a good idea to quote it:
myCommand "%Input%"
If choosing between OAuth versions, go with OAuth 2.0.
OAuth bearer tokens should only be used with a secure transport.
OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.
While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.
If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.
Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.
Here are the steps that worked for me for Ubuntu OS and using nvm
Go to nodejs website and get the last LTS version (for example in your current dater the version will be: x.y.z)
nvm install x.y.z
# In my case current version is: 14.15.4 (and had 14.15.3)
After that, execute nvm list
and you will get list of node versions installed by nvm.
Now you need to switch to the default last installed one by executing:
nvm alias default x.y.z
List again or run nvm --version
to check:
Update: sometimes even if i go over the steps above it doesn't work, so what i did was removing the symbolic links in /usr/local/bin
cd /usr/local/bin
sudo rm node npm npx
And relink:
sudo ln -s $(which node) /usr/local/bin/node
sudo ln -s $(which npm) /usr/local/bin/npm
sudo ln -s $(which npx) /usr/local/bin/npx
This is my aproximation:
Declare
Variableclob Clob;
Temp_Save Varchar2(32767); //whether it is greater than 4000
Begin
Select reportClob Into Temp_Save From Reporte Where Id=...;
Variableclob:=To_Clob(Temp_Save);
Dbms_Output.Put_Line(Variableclob);
End;

Quick fix, add this in your options:
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false)
Now you have no idea what host you're actually connecting to, because cURL will not verify the certificate in any way. Hope you enjoy man-in-the-middle attacks!
Or just add it to your current function:
/**
* Get a web file (HTML, XHTML, XML, image, etc.) from a URL. Return an
* array containing the HTTP server response header fields and content.
*/
function get_web_page( $url )
{
$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => "spider", // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
CURLOPT_SSL_VERIFYPEER => false // Disabled SSL Cert checks
);
$ch = curl_init( $url );

Here are two options, the first:
both <- list(first, second)
n <- unique(unlist(lapply(both, names)))
names(n) <- n
lapply(n, function(ni) unlist(lapply(both, `[[`, ni)))
and the second, which works only if they have the same structure:
apply(cbind(first, second),1,function(x) unname(unlist(x)))
Both give the desired result.
You can read in the data as chunks and save each chunk as pickle.
import pandas as pd
import pickle
in_path = "" #Path where the large file is
out_path = "" #Path to save the pickle files to
chunk_size = 400000 #size of chunks relies on your available memory
separator = "~"
reader = pd.read_csv(in_path,sep=separator,chunksize=chunk_size,
low_memory=False)
for i, chunk in enumerate(reader):
out_file = out_path + "/data_{}.pkl".format(i+1)
with open(out_file, "wb") as f:
pickle.dump(chunk,f,pickle.HIGHEST_PROTOCOL)
In the next step you read in the pickles and append each pickle to your desired dataframe.
import glob
pickle_path = "" #Same Path as out_path i.e. where the pickle files are
data_p_files=[]
for name in glob.glob(pickle_path + "/data_*.pkl"):
data_p_files.append(name)
df = pd.DataFrame([])
for i in range(len(data_p_files)):
df = df.append(pd.read_pickle(data_p_files[i]),ignore_index=True)

Yes, it's possible. But first read, "What happens when I change my username?"
To change your username, click your profile picture in the top right corner, then click Settings
. On the left side, click Account
. Then click Change username
.
Can I use a field of the type ... and retrieve it after the GET / POST method ...
Yes (haven't you tried?)
Are there any other ways of using hidden fields in PHP?
You mean other ways of retrieving the value? No.
Of course you can use hidden fields for what ever you want.
Btw. input
fiels have no end tag. So write either just <input ...>
or as self-closing tag <input .../>
.
You could directly inject the values into JavaScript:
//View.cshtml
<script type="text/javascript">
var arrayOfArrays = JSON.parse('@Html.Raw(Model.Addresses)');
</script>
See JSON.parse
, Html.Raw
Alternatively you can get the values via Ajax:
public ActionResult GetValues()
{
// logic
// Edit you don't need to serialize it just return the object
return Json(new { Addresses: lAddressGeocodeModel });
}
<script type="text/javascript">
$(function() {
$.ajax({
type: 'POST',
url: '@Url.Action("GetValues")',
success: function(result) {
// do something with result
}
});
});
</script>
See jQuery.ajax
<script>
function test(a) {
var x = a.selectedIndex;
alert(x);
}
</script>
<select onchange="test(this)" id="select_id">
<option value="0">-Select-</option>
<option value="1">Communication</option>
<option value="2">Communication</option>
<option value="3">Communication</option>
</select>
in the alert you'll see the INT value of the selected index, treat the selection as an array and you'll get the value
Here's how we made it work:
Clone your Git repository somewhere on your machine.
Open .git/config and add the following (from Maintaining a read-only SVN mirror of a Git repository):
[svn-remote "svn"]
url = https://your.svn.repo
fetch = :refs/remotes/git-svn
Now, from a console window, type these:
git svn fetch svn
git checkout -b svn git-svn
git merge master
Now, if it breaks here for whatever reason, type these three lines:
git checkout --theirs .
git add .
git commit -m "some message"
And finally, you can commit to SVN:
git svn dcommit
Note: I always scrap that folder afterwards.
The javascript array has a constructor that accepts the length of the array:
let arr = new Array<number>(3);
console.log(arr); // [undefined × 3]
However, this is just the initial size, there's no restriction on changing that:
arr.push(5);
console.log(arr); // [undefined × 3, 5]
Typescript has tuple types which let you define an array with a specific length and types:
let arr: [number, number, number];
arr = [1, 2, 3]; // ok
arr = [1, 2]; // Type '[number, number]' is not assignable to type '[number, number, number]'
arr = [1, 2, "3"]; // Type '[number, number, string]' is not assignable to type '[number, number, number]'
There are a few alternate ways to figure out the currently used python in Linux is:
which python
command.command -v python
commandtype python
commandSimilarly On Windows with Cygwin will also result the same.
kuvivek@HOSTNAME ~
$ which python
/usr/bin/python
kuvivek@HOSTNAME ~
$ whereis python
python: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4 /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gz
kuvivek@HOSTNAME ~
$ which python3
/usr/bin/python3
kuvivek@HOSTNAME ~
$ command -v python
/usr/bin/python
kuvivek@HOSTNAME ~
$ type python
python is hashed (/usr/bin/python)
If you are already in the python shell. Try anyone of these. Note: This is an alternate way. Not the best pythonic way.
>>> import os
>>> os.popen('which python').read()
'/usr/bin/python\n'
>>>
>>> os.popen('type python').read()
'python is /usr/bin/python\n'
>>>
>>> os.popen('command -v python').read()
'/usr/bin/python\n'
>>>
>>>
If you are not sure of the actual path of the python command and is available in your system, Use the following command.
pi@osboxes:~ $ which python
/usr/bin/python
pi@osboxes:~ $ readlink -f $(which python)
/usr/bin/python2.7
pi@osboxes:~ $
pi@osboxes:~ $ which python3
/usr/bin/python3
pi@osboxes:~ $
pi@osboxes:~ $ readlink -f $(which python3)
/usr/bin/python3.7

Try this:
window.open(url, '_blank');
This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)
Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?
By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...
-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications
If you are running you should be able to access any of those system properties to see if they have been set:
if (System.getProperty("com.sun.management.jmxremote") == null) {
System.out.println("JMX remote is disabled");
} else [
String portString = System.getProperty("com.sun.management.jmxremote.port");
if (portString != null) {
System.out.println("JMX running on port "
+ Integer.parseInt(portString));
}
}
Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts
or if it is set to an incorrect interface address then you can override it with the following:
-Djava.rmi.server.hostname=<IP address>
As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port
is actually the RMI port. This tells the client what port the JMX server is running on.
if (isset($_GET["id"])){
//do stuff
}

Some may take issue with changing the Bootstrap js (and perhaps validly so) but here is a two line approach to achieving this.
In bootstrap.js, look for the Collapse.prototype.show function and modify the this.$trigger call to add the html change as follows:
this.$trigger
.removeClass('collapsed')
.attr('aria-expanded', true)
.html('Collapse')
Likewise in the Collapse.prototype.hide function change it to
this.$trigger
.addClass('collapsed')
.attr('aria-expanded', false)
.html('Expand')
This will toggle the text between "Collapse" when everything is expanded and "Expand" when everything is collapsed.
Two lines. Done.
EDIT: longterm this won't work. bootstrap.js is part of a Nuget package so I don't think it was propogating my change to the server. As mentioned previously, not best practice anyway to edit bootstrap.js, so I implemented PSL's solution which worked great. Nonetheless, my solution will work locally if you need something quick just to try it out.
While Niemeyer's answer is a more correct answer to the question, you could also do the following:
<div>
<input data-bind="value: VMA.name" />
</div>
<div>
<input data-bind="value: VMB.name" />
</div>
<script type="text/javascript">
var viewModels = {
VMA: {name: ko.observable("Bob")},
VMB: {name: ko.observable("Ted")}
};
ko.applyBindings(viewModels);
</script>
This means you don't have to specify the DOM element, and you can even bind multiple models to the same element, like this:
<div>
<input data-bind="value: VMA.name() + ' and ' + VMB.name()" />
</div>
$(dialogElement).empty();
$(dialogElement).remove();
this fixes it for real
try this :
if (file_exists(FCPATH . 'uploads/pages/' . $image)) {
unlink(FCPATH . 'uploads/pages/' . $image);
}
While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event
argument to the setMaster
function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):
function AdminController($scope) {
$scope.setMaster = function(obj, $event){
console.log($event.target);
}
}
this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.
The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event
argument) would be:
<div ng-controller="AdminController">
<ul class="list-holder">
<li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
<a ng-click="setMaster(section)">{{section.name}}</a>
</li>
</ul>
<hr>
{{selected | json}}
</div>
where methods in the controller would look like this:
$scope.setMaster = function(section) {
$scope.selected = section;
}
$scope.isSelected = function(section) {
return $scope.selected === section;
}
Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/
Since Array.prototype.push adds one or more elements to the end of an array and returns the new length of the array, sometimes we want just to get the new up-to-date array so we can do something like so:
const arr = [1, 2, 3];
const val = 4;
arr.concat([val]); // [1, 2, 3, 4]
Or just:
[...arr, val] // [1, 2, 3, 4]

This script is a improvement of the script from Vector. I have made a little change to it. So this script works for every link with the class page-scroll in it.
At first without easing:
$("a.page-scroll").click(function() {
var targetDiv = $(this).attr('href');
$('html, body').animate({
scrollTop: $(targetDiv).offset().top
}, 1000);
});
For easing you will need Jquery UI:
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
Add this to the script:
'easeOutExpo'
Final
$("a.page-scroll").click(function() {
var targetDiv = $(this).attr('href');
$('html, body').animate({
scrollTop: $(targetDiv).offset().top
}, 1000, 'easeOutExpo');
});

This is just an explanation not addressed in other answers
At least in recent versions of Mysql, your first query is not committed.
If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.
What's going on?
When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.
So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE
, UPDATE
, INSERT
or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT
) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).
That's why the solution involves declaring handlers to immediately ROLLBACK
when an error happens.
Extra
Inside the handler you can also re-raise the error using RESIGNAL
, otherwise the stored procedure executes "Successfully"
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
ROLLBACK;
RESIGNAL;
END;
START TRANSACTION;
#.. Query 1 ..
#.. Query 2 ..
#.. Query 3 ..
COMMIT;
END

In the beginning I was also having a bit of trouble figuring out how this works so I wanted to post a better explanation of what is actually going on.
According to my research the best way to handle things like this is using the Command Bindings. What happens is a "Message" is broadcast to everything in the program. So what you have to do is use the CommandBinding
. What this essentially does is say "When you hear this Message do this".
So in the Question the User is trying to Close the Window. The first thing we need to do is setup our Functions that will be called when the SystemCommand.CloseWindowCommand
is broadcast. Optionally you can assign a Function that determines if the Command should be executed. An example would be closing a Form and checking if the User has saved.
void CloseApp( object target, ExecutedRoutedEventArgs e ) {
/*** Code to check for State before Closing ***/
this.Close();
}
void CloseAppCanExecute( object sender, CanExecuteRoutedEventArgs e ) {
/*** Logic to Determine if it is safe to Close the Window ***/
e.CanExecute = true;
}
Now we need to setup the "Connection" between the SystemCommands.CloseWindowCommand
and the CloseApp
and CloseAppCanExecute
<Window.CommandBindings>
<CommandBinding Command="SystemCommands.CloseWindowCommand"
Executed="CloseApp"
CanExecute="CloseAppCanExecute"/>
</Window.CommandBindings>
You can omit the CanExecute if you know that the Command should be able to always be executed Save might be a good example depending on the Application. Here is a Example:
<Window.CommandBindings>
<CommandBinding Command="SystemCommands.CloseWindowCommand"
Executed="CloseApp"/>
</Window.CommandBindings>
Finally you need to tell the UIElement to send out the CloseWindowCommand.
<Button Command="SystemCommands.CloseWindowCommand">
Its actually a very simple thing to do, just setup the link between the Command and the actual Function to Execute then tell the Control to send out the Command to the rest of your program saying "Ok everyone run your Functions for the Command CloseWindowCommand".
This is actually a very nice way of handing this because, you can reuse the Executed Function all over without having a wrapper like you would with say WinForms (using a ClickEvent and calling a function within the Event Function) like:
protected override void OnClick(EventArgs e){
/*** Function to Execute ***/
}
In WPF you attach the Function to a Command and tell the UIElement to execute the Function attached to the Command instead.
I hope this clears things up...
If you want the .wrapper
to be fullscreen, just add the following in the wrapper class:
position: absolute;
width: 100%;
height: 100%;
You can also add top: 0
and left:0
The requests package has a very nice API for HTTP requests, adding a custom header works like this (source: official docs):
>>> import requests
>>> response = requests.get(
... 'https://website.com/id', headers={'Authorization': 'access_token myToken'})
If you don't want to use an external dependency, the same thing using urllib2 of the standard library looks like this (source: the missing manual):
>>> import urllib2
>>> response = urllib2.urlopen(
... urllib2.Request('https://website.com/id', headers={'Authorization': 'access_token myToken'})
Use:
git diff 15dc8^!
as described in the following fragment of git-rev-parse(1) manpage (or in modern git gitrevisions(7) manpage):
Two other shorthands for naming a set that is formed by a commit and its parent commits exist. The r1^@ notation means all parents of r1. r1^! includes commit r1 but excludes all of its parents.
This means that you can use 15dc8^!
as a shorthand for 15dc8^..15dc8
anywhere in git where revisions are needed. For diff command the git diff 15dc8^..15dc8
is understood as git diff 15dc8^ 15dc8
, which means the difference between parent of commit (15dc8^
) and commit (15dc8
).
Note: the description in git-rev-parse(1)
manpage talks about revision ranges, where it needs to work also for merge commits, with more than one parent. Then r1^!
is "r1 --not r1^@
" i.e. "r1 ^r1^1 ^r1^2 ...
"
Also, you can use git show COMMIT
to get commit description and diff for a commit. If you want only diff, you can use git diff-tree -p COMMIT
This error creeps in if we make some spelling mistake in entering the variable name. Like in stored proc, I have the variable name x and in my insert statement I am using
insert into tablename values(y);
It will throw an error column not allowed here.
I have edited the function for you,
void readFile()
{
ifstream file;
file.open ("program.txt");
if (!file.is_open()) return;
string word;
while (file >> word)
{
cout<< word << '\n';
}
}
An extension of some other answers that covers hexadecimal representation:

{
return 10 + c - 'a';

Just use this css method:
body{
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

You can find the same answer here: How to disable text selection highlighting using CSS?
First, make sure the listener on database server (computer A) that receives client connection requests is running. To do so, run lsnrctl status
command.
In case, if you get TNS:no listener
message (see below image), it means listener service is not running. To start it, run lsnrctl start
command.
Second, for database operations and connectivity from remote clients, the following executables must be added to the Windows Firewall exception list: (see image)
Oracle_home\bin\oracle.exe - Oracle Database executable
Oracle_home\bin\tnslsnr.exe - Oracle Listener
Finally, install oracle instant client on client machine (computer B) and run:
sqlplus user/password@computerA:port/XE
After creating Set just convert it to List and get by index from List:
Set<String> stringsSet = new HashSet<>();
stringsSet.add("string1");
stringsSet.add("string2");
List<String> stringsList = new ArrayList<>(stringsSet);
stringsList.get(0); // "string1";
stringsList.get(1); // "string2";
There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.
The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:
element:before{
content: "_";
opacity: 0;
}
You can add any Git repository (or tarball) as a dependency to yarn
by specifying the remote URL (either HTTPS or SSH):
yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.
Here are some examples:
yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0 [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]
(Note: Fancybox v2.6.1 isn't available in the Git version.)
To support both npm and yarn, you can use the git+url syntax:
git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch
Yes, with set_index you can make Locality
your row index.
data.set_index('Locality', inplace=True)
If inplace=True
is not provided, set_index
returns the modified dataframe as a result.
Example:
> import pandas as pd
> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
['ABERFELDIE', 534000, 600000]],
columns=['Locality', 2005, 2006])
> df
Locality 2005 2006
0 ABBOTSFORD 427000 448000
1 ABERFELDIE 534000 600000
> df.set_index('Locality', inplace=True)
> df
2005 2006
Locality
ABBOTSFORD 427000 448000
ABERFELDIE 534000 600000
> df.loc['ABBOTSFORD']
2005 427000
2006 448000
Name: ABBOTSFORD, dtype: int64
> df.loc['ABBOTSFORD'][2005]
427000
> df.loc['ABBOTSFORD'].values
array([427000, 448000])
> df.loc['ABBOTSFORD'].tolist()
[427000, 448000]
Try this
self.tables.tableFooterView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 10.0f)];
Instead of using isnull
use a case
, because of performance it is better the case.
case when campo is null then '' else campo end
In your issue you need to do this:
case when campo is null then '' else
case when len(campo) = 0 then '' else campo en
end
Code like this:
create table #tabla(
id int,
campo varchar(10)
)
insert into #tabla
values(1,null)
insert into #tabla
values(2,'')
insert into #tabla
values(3,null)
insert into #tabla
values(4,'dato4')
insert into #tabla
values(5,'dato5')
select id, case when campo is null then 'DATA NULL' else
case when len(campo) = 0 then 'DATA EMPTY' else campo end
end
from #tabla
drop table #tabla
None of these answers worked for me, when all I had was a list of directories. Then I stumbled upon the solution! You have to add -r
to --files-from
because -a
will not be recursive in this scenario (who knew?!).
rsync -aruRP --files-from=directory.list . ../new/location
Pass in the straight XML instead of a dictionary.

This'll download the .msi (or .pkg for mac) which will do all the installation and paths for you, unlike the selected answer.
https://github.com/cognitom/paper-css seems to solve all my needs.
Front-end printing solution - previewable and live-reloadable!
Since a jQuery object inherits from an array, and this array contains the selected DOM elements. Saying you're using an id and so the element should be unique within the DOM, you could perform a direct call to submit by doing :
$(".nextbutton").click(function() {
$("#formID")[0].submit();
});
This eventually helped me:
var x = 0;
var buttonText = 'LOADING';
$('#startbutton').click(function(){
$(this).text(buttonText);
window.setTimeout(addDotToButton,2000);
})
function addDotToButton(){
x++;
buttonText += '.';
$('#startbutton').text(buttonText);
if (x < 4) window.setTimeout(addDotToButton, 2000);
else location.reload(true);
}
Taking a guess at what it is you're asking for. I'm assuming by millisecond frame timer you're looking for something that acts like the following,
double mticks()
{
struct timeval tv;
gettimeofday(&tv, 0);
return (double) tv.tv_usec / 1000 + tv.tv_sec * 1000;
}
but uses std::chrono
instead,
double mticks()
{
typedef std::chrono::high_resolution_clock clock;
typedef std::chrono::duration<float, std::milli> duration;
static clock::time_point start = clock::now();
duration elapsed = clock::now() - start;
return elapsed.count();
}
Hope this helps.
This command should do the trick (provided that you installed it using a dpkg-based packet manager):
aptitude purge ruby
If you want to pass a JavaScript object/hash (ie. an associative array in PHP) then you would do:
$.post('/url/to/page', {'key1': 'value', 'key2': 'value'});
If you wanna pass an actual array (ie. an indexed array in PHP) then you can do:
$.post('/url/to/page', {'someKeyName': ['value','value']});
If you want to pass a JavaScript array then you can do:
$.post('/url/to/page', {'someKeyName': variableName});
You can use the available()
method to ask the stream whether there is any data available at the moment you call it. However, that function isn't guaranteed to work on all types of input streams. That means that you can't use available()
to determine whether a call to read()
will actually block or not.
For those who would like to do this using a single function inside the IF statement, I use
=IF(COUNTIF(A1,"*TEXT*"),TrueValue,FalseValue)
to see if the substring TEXT is in cell A1
[NOTE: TEXT needs to have asterisks around it]
Use print("use this bracket -sample text")
In Python 3 print "Hello world"
gives invalid syntax error.
To display string content in Python3 have to use this ("Hello world")
brackets.
I will just add a blank ("") to the end of the variable and do the comparison. Something like below should work even when that variable is null. You can also trim the variable just in case of spaces.
If provider & "" <> "" Then
url = url & "&provider=" & provider
End if
Based on SourceSimian's response; this worked on Windows domain user accounts. Note that the Username does not have domain included,

The best answer is to add a Resources/.gitignore file under Resources containing:
# Ignore any file in this directory except for this file and *.foo files
*
!/.gitignore
!*.foo
If you are unwilling or unable to add that .gitignore file, there is an inelegant solution:
# Ignore any file but *.foo under Resources. Update this if we add deeper directories
Resources/*
!Resources/*/
!Resources/*.foo
Resources/*/*
!Resources/*/*/
!Resources/*/*.foo
Resources/*/*/*
!Resources/*/*/*/
!Resources/*/*/*.foo
Resources/*/*/*/*
!Resources/*/*/*/*/
!Resources/*/*/*/*.foo
You will need to edit that pattern if you add directories deeper than specified.
For vector initialisation -
vector<int> v = {10,20,30}
can be done if you have C++11 compiler.
Else, you can have an array of the data and then use a for loop.
int array[] = {10,20,30}
for(unsigned int i=0; i<sizeof(array)/sizeof(array[0]); i++)
{
v.push_back(array[i]);
}
Apart from these, there are various other ways described above using some code. In my opinion, these ways are easy to remember and quick to write.
A possibility is that the element is currently unclickable because it is not visible. Reasons for this may be that another element is covering it up or it is not in view, i.e. it is outside the currently view-able area.
Try this
from selenium.webdriver.common.action_chains import ActionChains
button = driver.find_element_by_class_name(u"infoDismiss")
driver.implicitly_wait(10)
ActionChains(driver).move_to_element(button).click(button).perform()
For reloading the page for a given route path :-
$location.path('/path1/path2');
$route.reload();
just to toss it out for posterity: it can sometimes be preferable to generate a random string using an initial character set string. This is useful if the string is supposed to be entered manually by a human; excluding 0, O, 1, and l can help reduce user error.
var alpha = "abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789"
// generates a random string of fixed size
func srand(size int) string {
buf := make([]byte, size)
for i := 0; i < size; i++ {
buf[i] = alpha[rand.Intn(len(alpha))]
}
return string(buf)
}
and I typically set the seed inside of an init()
block. They're documented here: http://golang.org/doc/effective_go.html#init
This looks like one case where it is better to use setAttribute:
Dev.Opera — Efficient JavaScript
var posElem = document.getElementById('animation');
var newStyle = 'background: ' + newBack + ';' +
'color: ' + newColor + ';' +
'border: ' + newBorder + ';';
if(typeof(posElem.style.cssText) != 'undefined') {
posElem.style.cssText = newStyle;
} else {
posElem.setAttribute('style', newStyle);
}
Let'e me give an example:
client connect to server, and send 1MB data to server every 1 second.
server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer
in the client side will be full.
Code in client side:
#include <arpa/inet.h>
#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <stdlib.h>
#include <string.h>
#define exit_if(r, ...) \
if (r) { \
printf(__VA_ARGS__); \
printf("%s:%d error no: %d error msg %s\n", __FILE__, __LINE__, errno, strerror(errno)); \
exit(1); \
}
void setNonBlock(int fd) {
int flags = fcntl(fd, F_GETFL, 0);
exit_if(flags < 0, "fcntl failed");
int r = fcntl(fd, F_SETFL, flags | O_NONBLOCK);
exit_if(r < 0, "fcntl failed");
}
void test_full_sock_buf_1(){
short port = 8000;
struct sockaddr_in addr;
memset(&addr, 0, sizeof addr);
addr.sin_family = AF_INET;
addr.sin_port = htons(port);
addr.sin_addr.s_addr = INADDR_ANY;
int fd = socket(AF_INET, SOCK_STREAM, 0);
exit_if(fd<0, "create socket error");
int ret = connect(fd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
exit_if(ret<0, "connect to server error");
setNonBlock(fd);
printf("connect to server success");
const int LEN = 1024 * 1000;
char msg[LEN]; // 1MB data
memset(msg, 'a', LEN);
for (int i = 0; i < 1000; ++i) {
int len = send(fd, msg, LEN, 0);
printf("send: %d, erron: %d, %s \n", len, errno, strerror(errno));
sleep(1);
}
}
int main(){
test_full_sock_buf_1();
return 0;
}
Code in server side:
#include <arpa/inet.h>
#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <stdlib.h>
#include <string.h>
#define exit_if(r, ...) \
if (r) { \
printf(__VA_ARGS__); \
printf("%s:%d error no: %d error msg %s\n", __FILE__, __LINE__, errno, strerror(errno)); \
exit(1); \
}
void test_full_sock_buf_1(){
int listenfd = socket(AF_INET, SOCK_STREAM, 0);
exit_if(listenfd<0, "create socket error");
short port = 8000;
struct sockaddr_in addr;
memset(&addr, 0, sizeof addr);
addr.sin_family = AF_INET;
addr.sin_port = htons(port);
addr.sin_addr.s_addr = INADDR_ANY;
int r = ::bind(listenfd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
exit_if(r<0, "bind socket error");
r = listen(listenfd, 100);
exit_if(r<0, "listen socket error");
struct sockaddr_in raddr;
socklen_t rsz = sizeof(raddr);
int cfd = accept(listenfd, (struct sockaddr *) &raddr, &rsz);
exit_if(cfd<0, "accept socket error");
sockaddr_in peer;
socklen_t alen = sizeof(peer);
getpeername(cfd, (sockaddr *) &peer, &alen);
printf("accept a connection from %s:%d\n", inet_ntoa(peer.sin_addr), ntohs(peer.sin_port));
printf("but now I will sleep 15 second, then exit");
sleep(15);
}
Start server side, then start client side.
server side may output:
accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0
client side may output:
connect to server successsend: 1024000, erron: 0, Success
send: 1024000, erron: 0, Success
send: 1024000, erron: 0, Success
send: 552190, erron: 0, Success
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 11, Resource temporarily unavailable
send: -1, erron: 104, Connection reset by peer

send: -1, erron: 32, Broken pipe
send: -1, erron: 32, Broken pipe
send: -1, erron: 32, Broken pipe
send: -1, erron: 32, Broken pipe
You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer
get full, but you still send data, so you may get Resource temporarily unavailable
error.
You can also use the AddRange
method
listBox1.Items.AddRange(myList.ToArray());
In Python 3, dict.values()
(along with dict.keys()
and dict.items()
) returns a view
, rather than a list. See the documentation here. You therefore need to wrap your call to dict.values()
in a call to list
like so:
v = list(d.values())
{names[i]:v[i] for i in range(len(names))}
You need to define static variables in a translation unit, unless they are of integral types.
In your header:
private:
static const char *SOMETHING;
static const int MyInt = 8; // would be ok
In the .cpp file:
const char *YourClass::SOMETHING = "something";
C++ standard, 9.4.2/4:
If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression. In that case, the member can appear in integral constant expressions within its scope. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.
The big difference between Bootstrap 2 and Bootstrap 3 is that Bootstrap 3 is "mobile first".
That means the default styles are designed for mobile devices and in the case of Navbars, that means it's "collapsed" by default and "expands" when it reaches a certain minimum size.
Bootstrap 3's site actually has a "hint" as to what to do: http://getbootstrap.com/components/#navbar
Customize the collapsing point
Depending on the content in your navbar, you might need to change the point at which your navbar switches between collapsed and horizontal mode. Customize the @grid-float-breakpoint variable or add your own media query.
If you're going to re-compile your LESS, you'll find the noted LESS variable in the variables.less
file. It's currently set to "expand" @media (min-width: 768px)
which is a "small screen" (ie. a tablet) by Bootstrap 3 terms.
@grid-float-breakpoint: @screen-tablet;
If you want to keep the collapsed a little longer you can adjust it like such:
@grid-float-breakpoint: @screen-desktop;
(992px break-point)
or expand sooner
@grid-float-breakpoint: @screen-phone
(480px break-point)
If you want to have it expand later, and not deal with re-compiling the LESS, you'll have to overwrite the styles that get applied at the 768px
media query and have them return to the previous value. Then re-add them at the appropriate time.
I'm not sure if there's a better way to do it. Recompiling the Bootstrap LESS to your needs is the best (easiest) way. Otherwise, you'll have to find all the CSS media queries that affect your Navbar, overwrite them to default styles @ the 768px width and then revert them back at a higher min-width.
Recompiling the LESS will do all that magic for you just by changing the variable. Which is pretty much the point of LESS/SASS pre-compilers. =)
(note, I did look them all up, it's about 100 lines of code, which is annoy enough for me to drop the idea and just re-compile Bootstrap for a given project and avoid messing something up by accident)
I hope that helps!
Cheers!
Here is exp.
$date_search_strtotime = strtotime(date("Y-m-d"));
echo 'Now strtotime date : '.$date_search_strtotime;
echo '<br>';
echo 'Now date from strtotime : '.date('Y-m-d',$date_search_strtotime);
This is flask.jsonify()

if __debug__:
_assert_have_json()
return current_app.response_class(json.dumps(dict(*args, **kwargs),
indent=None if request.is_xhr else 2), mimetype='application/json')
The json

Union has not good performance : this article describe about compare them with together
var dict = list2.ToDictionary(p => p.Number);
foreach (var person in list1)
{
dict[person.Number] = person;
}
var merged = dict.Values.ToList();
Lists and LINQ merge: 4820ms
Dictionary merge: 16ms
HashSet and IEqualityComparer: 20ms
LINQ Union and IEqualityComparer: 24ms
If you want your numbers in ascending order you can add them into a set and then sort the set into an ascending list.
s = set()
if number1 not in s:
s.add(number1)
if number2 not in s:
s.add(number2)
...
s = sorted(s) #Now a list in ascending order
function parseQuery(queryString) {
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
query[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
}
return query;
}
Turns query string like hello=1&another=2
into object {hello: 1, another: 2}
. From there, it's easy to extract the variable you need.
That said, it does not deal with array cases such as "hello=1&hello=2&hello=3"
. To work with this, you must check whether a property of the object you make exists before adding to it, and turn the value of it into an array, pushing any additional bits.
It works fine for me...

My example code was correct and the issue was something else in my actual code. Still, I know it was difficult to find examples of this so I'm answering it in case someone else is looking.

As of June 15, 2015 you may use Set()
to create a unique array:
var uniqueArray = [...new Set(array)]
For your Example:
var data = ["X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11"]
var newArray = [...new Set(data)]
console.log(newArray)
>> ["X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11"]
If the program won't work without the files it seems like splitting them into a separate repo is a bad idea. We have large test suites that we break into a separate repo but those are truly "auxiliary" files.
However, you may be able to manage the files in a separate repo and then use git-submodule
to pull them into your project in a sane way. So, you'd still have the full history of all your source but, as I understand it, you'd only have the one relevant revision of your images submodule. The git-submodule
facility should help you keep the correct version of the code in line with the correct version of the images.
Here's a good introduction to submodules from Git Book.
1. Choose project, right click, in context menu, choose Show in Explorer
(on Mac, select Reveal in Finder
).
2. Choose menu File \ Close Project
3. In Windows Explorer, press Del or Shift+Del for permanent delete.
4. At IntelliJ IDEA startup windows, hover cursor on old project name (what has been deleted) press Del for delelte.
for x in numbers:
print "{:10.4f}".format(x)
prints
23.2300
0.1233
1.0000
4.2230
9887.2000
The format specifier inside the curly braces follows the Python format string syntax. Specifically, in this case, it consists of the following parts:
format()
" – in this case the x
as the only argument.10.4f
part after the colon is the format specification.f
denotes fixed-point notation.10
is the total width of the field being printed, lefted-padded by spaces.4
is the number of digits after the decimal point.To avoid error, an important point about the new dataset is the name of independent variable. It must be the same as reported in the model. Another way is to nest the two function without creating a new dataset
model <- lm(Coupon ~ Total, data=df)
predict(model, data.frame(Total=c(79037022, 83100656, 104299800)))
Pay attention on the model. The next two commands are similar, but for predict function, the first work the second don't work.
model <- lm(Coupon ~ Total, data=df) #Ok
model <- lm(df$Coupon ~ df$Total) #Ko

Most of the work in overloading operators is boiler-plate code. That is little wonder, since operators are merely syntactic sugar, their actual work could be done by (and often is forwarded to) plain functions. But it is important that you get this boiler-plate code right. If you fail, either your operator’s code won’t compile or your users’ code won’t compile or your users’ code will behave surprisingly.
There's a lot to be said about assignment. However, most of it has already been said in GMan's famous Copy-And-Swap FAQ, so I'll skip most of it here, only listing the perfect assignment operator for reference:
X& X::operator=(X rhs)
{
swap(rhs);
return *this;
}
The bitshift operators <<
and >>
, although still used in hardware interfacing for the bit-manipulation functions they inherit from C, have become more prevalent as overloaded stream input and output operators in most applications. For guidance overloading as bit-manipulation operators, see the section below on Binary Arithmetic Operators. For implementing your own custom format and parsing logic when your object is used with iostreams, continue.
The stream operators, among the most commonly overloaded operators, are binary infix operators for which the syntax specifies no restriction on whether they should be members or non-members. Since they change their left argument (they alter the stream’s state), they should, according to the rules of thumb, be implemented as members of their left operand’s type. However, their left operands are streams from the standard library, and while most of the stream output and input operators defined by the standard library are indeed defined as members of the stream classes, when you implement output and input operations for your own types, you cannot change the standard library’s stream types. That’s why you need to implement these operators for your own types as non-member functions. The canonical forms of the two are these:
std::ostream& operator<<(std::ostream& os, const T& obj)
{
// write obj to stream
return os;
}
std::istream& operator>>(std::istream& is, T& obj)
{
// read obj from stream
if( /* no valid object of T found in stream */ )
is.setstate(std::ios::failbit);
return is;
}
When implementing operator>>
, manually setting the stream’s state is only necessary when the reading itself succeeded, but the result is not what would be expected.
The function call operator, used to create function objects, also known as functors, must be defined as a member function, so it always has the implicit this
argument of member functions. Other than this, it can be overloaded to take any number of additional arguments, including zero.
Here's an example of the syntax:
class foo {
public:
// Overloaded call operator
int operator()(const std::string& y) {
// ...
}
};
Usage:
foo f;
int a = f("hello");
Throughout the C++ standard library, function objects are always copied. Your own function objects should therefore be cheap to copy. If a function object absolutely needs to use data which is expensive to copy, it is better to store that data elsewhere and have the function object refer to it.
The binary infix comparison operators should, according to the rules of thumb, be implemented as non-member functions1. The unary prefix negation !
should (according to the same rules) be implemented as a member function. (but it is usually not a good idea to overload it.)
The standard library’s algorithms (e.g. std::sort()
) and types (e.g. std::map
) will always only expect operator<
to be present. However, the users of your type will expect all the other operators to be present, too, so if you define operator<
, be sure to follow the third fundamental rule of operator overloading and also define all the other boolean comparison operators. The canonical way to implement them is this:
inline bool operator==(const X& lhs, const X& rhs){ /* do actual comparison */ }
inline bool operator!=(const X& lhs, const X& rhs){return !operator==(lhs,rhs);}
inline bool operator< (const X& lhs, const X& rhs){ /* do actual comparison */ }
inline bool operator> (const X& lhs, const X& rhs){return operator< (rhs,lhs);}
inline bool operator<=(const X& lhs, const X& rhs){return !operator> (lhs,rhs);}
inline bool operator>=(const X& lhs, const X& rhs){return !operator< (lhs,rhs);}
The important thing to note here is that only two of these operators actually do anything, the others are just forwarding their arguments to either of these two to do the actual work.
The syntax for overloading the remaining binary boolean operators (||
, &&
) follows the rules of the comparison operators. However, it is very unlikely that you would find a reasonable use case for these2.
1 As with all rules of thumb, sometimes there might be reasons to break this one, too. If so, do not forget that the left-hand operand of the binary comparison operators, which for member functions will be *this
, needs to be const
, too. So a comparison operator implemented as a member function would have to have this signature:
bool operator<(const X& rhs) const { /* do actual comparison with *this */ }
(Note the const
at the end.)
2 It should be noted that the built-in version of ||
and &&
use shortcut semantics. While the user defined ones (because they are syntactic sugar for method calls) do not use shortcut semantics. User will expect these operators to have shortcut semantics, and their code may depend on it, Therefore it is highly advised NEVER to define them.
The unary increment and decrement operators come in both prefix and postfix flavor. To tell one from the other, the postfix variants take an additional dummy int argument. If you overload increment or decrement, be sure to always implement both prefix and postfix versions. Here is the canonical implementation of increment, decrement follows the same rules:
class X {
X& operator++()
{
// do actual increment
return *this;
}
X operator++(int)
{
X tmp(*this);
operator++();
return tmp;
}
};
Note that the postfix variant is implemented in terms of prefix. Also note that postfix does an extra copy.2
Overloading unary minus and plus is not very common and probably best avoided. If needed, they should probably be overloaded as member functions.
2 Also note that the postfix variant does more work and is therefore less efficient to use than the prefix variant. This is a good reason to generally prefer prefix increment over postfix increment. While compilers can usually optimize away the additional work of postfix increment for built-in types, they might not be able to do the same for user-defined types (which could be something as innocently looking as a list iterator). Once you got used to do i++
, it becomes very hard to remember to do ++i
instead when i
is not of a built-in type (plus you'd have to change code when changing a type), so it is better to make a habit of always using prefix increment, unless postfix is explicitly needed.
For the binary arithmetic operators, do not forget to obey the third basic rule operator overloading: If you provide +
, also provide +=
, if you provide -
, do not omit -=
, etc. Andrew Koenig is said to have been the first to observe that the compound assignment operators can be used as a base for their non-compound counterparts. That is, operator +
is implemented in terms of +=
, -
is implemented in terms of -=
etc.
According to our rules of thumb, +
and its companions should be non-members, while their compound assignment counterparts (+=
etc.), changing their left argument, should be a member. Here is the exemplary code for +=
and +
; the other binary arithmetic operators should be implemented in the same way:
class X {
X& operator+=(const X& rhs)
{
// actual addition of rhs to *this
return *this;
}
};
inline X operator+(X lhs, const X& rhs)
{
lhs += rhs;
return lhs;
}
operator+=
returns its result per reference, while operator+
returns a copy of its result. Of course, returning a reference is usually more efficient than returning a copy, but in the case of operator+
, there is no way around the copying. When you write a + b
, you expect the result to be a new value, which is why operator+
has to return a new value.3
Also note that operator+
takes its left operand by copy rather than by const reference. The reason for this is the same as the reason giving for operator=
taking its argument per copy.
The bit manipulation operators ~
&
|
^
<<
>>
should be implemented in the same way as the arithmetic operators. However, (except for overloading <<
and >>
for output and input) there are very few reasonable use cases for overloading these.
3 Again, the lesson to be taken from this is that a += b
is, in general, more efficient than a + b
and should be preferred if possible.
The array subscript operator is a binary operator which must be implemented as a class member. It is used for container-like types that allow access to their data elements by a key. The canonical form of providing these is this:
class X {
value_type& operator[](index_type idx);
const value_type& operator[](index_type idx) const;
// ...
};
Unless you do not want users of your class to be able to change data elements returned by operator[]
(in which case you can omit the non-const variant), you should always provide both variants of the operator.
If value_type is known to refer to a built-in type, the const variant of the operator should better return a copy instead of a const reference:
class X {
value_type& operator[](index_type idx);
value_type operator[](index_type idx) const;
// ...
};
For defining your own iterators or smart pointers, you have to overload the unary prefix dereference operator *
and the binary infix pointer member access operator ->
:
class my_ptr {
value_type& operator*();
const value_type& operator*() const;
value_type* operator->();
const value_type* operator->() const;
};
Note that these, too, will almost always need both a const and a non-const version.
For the ->
operator, if value_type
is of class
(or struct
or union
) type, another operator->()
is called recursively, until an operator->()
returns a value of non-class type.
The unary address-of operator should never be overloaded.
For operator->*()
see this question. It's rarely used and thus rarely ever overloaded. In fact, even iterators do not overload it.
