My solution:
// jQuery plugin to prevent double submission of forms
$.fn.preventDoubleSubmission = function () {
var $form = $(this);
$form.find('[type="submit"]').click(function () {
$(this).prop('disabled', true);
$form.submit();
});
// Keep chainability
return this;
};
Accepted answer suggest using nohup. I would rather suggest using pm2. Using pm2 over nohup has many advantages, like keeping the application alive, maintain log files for application and lot more other features. For more detail check this out.
To install pm2 you need to download npm. For Debian based system
sudo apt-get install npm
and for Redhat
sudo yum install npm
Or you can follow these instruction. After installing npm use it to install pm2
npm install pm2@latest -g
Once its done you can start your application by
$ pm2 start app.js # Start, Daemonize and auto-restart application (Node)
$ pm2 start app.py # Start, Daemonize and auto-restart application (Python)
For process monitoring use following commands:
$ pm2 list # List all processes started with PM2
$ pm2 monit # Display memory and cpu usage of each app
$ pm2 show [app-name] # Show all informations about application
Manage processes using either app name or process id or manage all processes together:
$ pm2 stop <app_name|id|'all'|json_conf>
$ pm2 restart <app_name|id|'all'|json_conf>
$ pm2 delete <app_name|id|'all'|json_conf>
Log files can be found in
$HOME/.pm2/logs #contain all applications logs
Binary executable files can also be run using pm2. You have to made a change into the jason file. Change the "exec_interpreter" : "node"
, to "exec_interpreter" : "none".
(see the attributes section).
#include <stdio.h>
#include <unistd.h> //No standard C library
int main(void)
{
printf("Hello World\n");
sleep (100);
printf("Hello World\n");
return 0;
}
Compiling above code
gcc -o hello hello.c
and run it with np2 in the background
pm2 start ./hello
This is the is simplest solution that worked for me.
<div
contentEditable='true'
onInput={e => console.log('Text inside div', e.currentTarget.textContent)}
>
Text inside div
</div>
Here is a great cheat sheet for vim:
You must try this in keydown event
here is the code for that :
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
MessageBox.Show("Enter pressed");
}
}
Update :
Also you can do this with keypress event.
Try This :
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == Convert.ToChar(Keys.Return))
{
MessageBox.Show("Key pressed");
}
}
Mongoose uses the mongodb-native driver, which uses the custom ObjectID type. You can compare ObjectIDs with the .equals()
method. With your example, results.userId.equals(AnotherMongoDocument._id)
. The ObjectID type also has a toString()
method, if you wish to store a stringified version of the ObjectID in JSON format, or a cookie.
If you use ObjectID = require("mongodb").ObjectID
(requires the mongodb-native library) you can check if results.userId
is a valid identifier with results.userId instanceof ObjectID
.
Etc.
Give a class to your cell containing the icon
<td class="icon"><i class="icon-ok"></i></td>
and then
.icon{
text-align: center;
}
the next code can be used in 2 modes, mode 1 save the html code to a image, mode 2 save the html code to a canvas.
this code work with the library: https://github.com/tsayen/dom-to-image
*the "id_div" is the id of the element html that you want to transform.
**the "canvas_out" is the id of the div that will contain the canvas so try this code. :
function Guardardiv(id_div){
var mode = 2 // default 1 (save to image), mode 2 = save to canvas
console.log("Process start");
var node = document.getElementById(id_div);
// get the div that will contain the canvas
var canvas_out = document.getElementById('canvas_out');
var canvas = document.createElement('canvas');
canvas.width = node.scrollWidth;
canvas.height = node.scrollHeight;
domtoimage.toPng(node).then(function (pngDataUrl) {
var img = new Image();
img.onload = function () {
var context = canvas.getContext('2d');
context.drawImage(img, 0, 0);
};
if (mode == 1){ // save to image
downloadURI(pngDataUrl, "salida.png");
}else if (mode == 2){ // save to canvas
img.src = pngDataUrl;
canvas_out.appendChild(img);
}
console.log("Process finish");
});
}
so, if you want to save to image just add this function:
function downloadURI(uri, name) {
var link = document.createElement("a");
link.download = name;
link.href = uri;
document.body.appendChild(link);
link.click();
}
Example of use:
<html>
<head>
</script src="/dom-to-image.js"></script>
</head>
<body>
<div id="container">
All content that want to transform
</div>
<button onclick="Guardardiv('container');">Convert<button>
<!-- if use mode 2 -->
<div id="canvas_out"></div>
</html>
Comment if that work. Comenten si les sirvio :)
JQuery and Mootools are just a toolbox with lot of tools of your project. Backbone acts like an architecture or a backbone for your project on which you can build an application using JQuery or Mootools.
You may try creating a new project in netbeans and then copy and and paste the files into it. I usually experience this problem when the project wasn't created in netbeans.
The emulator does not provide virtual hardware for Wi-Fi if you use API 24 or earlier. From the Android Developers website:
When using an AVD with API level 25 or higher, the emulator provides a simulated Wi-Fi access point ("AndroidWifi"), and Android automatically connects to it.
You can disable Wi-Fi in the emulator by running the emulator with the command-line parameter -feature -Wifi.
https://developer.android.com/studio/run/emulator.html#wi-fi
What's not supported
The Android Emulator doesn't include virtual hardware for the following:
- Bluetooth
- NFC
- SD card insert/eject
- Device-attached headphones
- USB
The watch emulator for Android Wear doesn't support the Overview (Recent Apps) button, D-pad, and fingerprint sensor.

I can't tell you whether or not this is correct, but I am using a Bitnami image over Google Compute App Engine. I has having problems with plugins and migration, and after further messing things up by chmod'ing permissions, I found these three lines which solved all my problems. Not sure if it's the proper way but worked for me.
sudo chown -R bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/
sudo find /opt/bitnami/apps/wordpress/htdocs/ -type f -exec chmod 664 {} \;
sudo find /opt/bitnami/apps/wordpress/htdocs/ -type d -exec chmod 775 {} \;
Implicit is when you define your interface via a member on your class. Explicit is when you define methods within your class on the interface. I know that sounds confusing but here is what I mean: IList.CopyTo
would be implicitly implemented as:
public void CopyTo(Array array, int index)
{
throw new NotImplementedException();
}
and explicitly as:
void ICollection.CopyTo(Array array, int index)
{
throw new NotImplementedException();
}
The difference is that implicit implementation allows you to access the interface through the class you created by casting the interface as that class and as the interface itself. Explicit implementation allows you to access the interface only by casting it as the interface itself.
MyClass myClass = new MyClass(); // Declared as concrete class
myclass.CopyTo //invalid with explicit
((IList)myClass).CopyTo //valid with explicit.
I use explicit primarily to keep the implementation clean, or when I need two implementations. Regardless, I rarely use it.
I am sure there are more reasons to use/not use explicit that others will post.
See the next post in this thread for excellent reasoning behind each.
And this should work as well..
ConcurrentMap<Integer, String> running = ... create and populate map
Set<Entry<Integer, String>> set = running.entrySet();
for (Entry<Integer, String> entry : set)
{
if (entry.getKey()>600000)
{
set.remove(entry.getKey());
}
}
A very cool util is journalctl
.
For example, to show syslog to console: journalctl -t <syslog-ident>
, where <syslog-ident>
is identity you gave to function openlog
to initialize syslog.
I'm one of the maintainers of jackson-datatype-money, so take this answer with a grain of salt since I'm certainly biased. The module should cover your needs and it's pretty light-weight (no additional runtime dependencies). In addition it's mentioned in the Jackson docs, Spring docs and there were even some discussions already about how to integrate it into the official ecosystem of Jackson.
Download Json.NET from here http://james.newtonking.com/projects/json-net.aspx
name deserializedName = JsonConvert.DeserializeObject<name>(jsonData);
Use this code:
var result=JsonConvert.DeserializeObject<List<yourObj>>(jsonString);
I found weigan's answer best one in this page, here is how you can use that in Xamarin.Android
:
public int GetScreenWidth()
{
return Resources.System.DisplayMetrics.WidthPixels;
}
public int GetScreenHeight()
{
return Resources.System.DisplayMetrics.HeightPixels;
}
text-shadow: -1px 0 black, 0 1px black, 1px 0 black, 0 -1px black;
SQL Server Reporting Services (SSRS)
SSRS can remain active even if you uninstall SQL Server.
To stop the service:
Open SQL Server Configuration Manager. Select “SQL Server Services” in the left-hand pane. Double-click “SQL Server Reporting Services”. Hit Stop. Switch to the Service tab and set the Start Mode to “Manual”.
Skype
Irritatingly, Skype can switch to port 80. To disable it, select Tools > Options > Advanced > Connection
then uncheck “Use port 80 and 443 as alternatives for incoming connections”
.
IIS (Microsoft Internet Information Server)
For Windows 7 (or vista) its the most likely culprit. You can stop the service from the command line.
Open command line cmd.exe
and type:
net stop was /y
For older versions of Windows type:
net stop iisadmin /y
Other
If this does not solve the problem further detective work is necessary if IIS, SSRS and Skype are not to blame. Enter the following on the command line:
netstat -ao
The active TCP addresses and ports will be listed. Locate the line with local address “0.0.0.0:80" and note the PID value. Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.
The params
parameter modifier gives callers a shortcut syntax for passing multiple arguments to a method. There are two ways to call a method with a params
parameter:
1) Calling with an array of the parameter type, in which case the params
keyword has no effect and the array is passed directly to the method:
object[] array = new[] { "1", "2" };
// Foo receives the 'array' argument directly.
Foo( array );
2) Or, calling with an extended list of arguments, in which case the compiler will automatically wrap the list of arguments in a temporary array and pass that to the method:
// Foo receives a temporary array containing the list of arguments.
Foo( "1", "2" );
// This is equivalent to:
object[] temp = new[] { "1", "2" );
Foo( temp );
In order to pass in an object array to a method with a "params object[]
" parameter, you can either:
1) Create a wrapper array manually and pass that directly to the method, as mentioned by lassevk:
Foo( new object[] { array } ); // Equivalent to calling convention 1.
2) Or, cast the argument to object
, as mentioned by Adam, in which case the compiler will create the wrapper array for you:
Foo( (object)array ); // Equivalent to calling convention 2.
However, if the goal of the method is to process multiple object arrays, it may be easier to declare it with an explicit "params object[][]
" parameter. This would allow you to pass multiple arrays as arguments:
void Foo( params object[][] arrays ) {
foreach( object[] array in arrays ) {
// process array
}
}
...
Foo( new[] { "1", "2" }, new[] { "3", "4" } );
// Equivalent to:
object[][] arrays = new[] {
new[] { "1", "2" },
new[] { "3", "4" }
};
Foo( arrays );
Edit: Raymond Chen describes this behavior and how it relates to the C# specification in a new post.
In Windows inorder to set
Step 1 : Right Click on MyComputer and click on properties .
Step 2 : Click on Advanced tab
Step 3: Click on Environment Variables
Step 4: Create a new class path for JAVA_HOME
Step 5: Enter the Variable name as JAVA_HOME and the value to your jdk bin path ie c:\Programfiles\Java\jdk-1.6\bin and
NOTE Make sure u start with .;
in the Value so that it doesn't corrupt the other environment variables which is already set.
Step 6 : Follow the Above step and edit the Path in System Variables add the following ;c:\Programfiles\Java\jdk-1.6\bin
in the value column.
Step 7 :Your are done setting up your environment variables for your Java , In order to test it go to command prompt and type
java
who will get a list of help doc
In order make sure whether compiler is setup Type in cmd
javac
who will get a list related to javac
Hope this Helps !

Assume that you have
const appRoutes: Routes = [
{path: 'recipes', component: RecipesComponent }
];
<a routerLink ="recipes">Recipes</a>
It means that clicking Recipes hyperlink will jump to http://localhost:4200/recipes
Assume that the parameter is 1
<a [routerLink] = "['/recipes', parameter]"></a>
It means that passing dynamic parameter, 1 to the link, then you navigate to http://localhost:4200/recipes/1
I first came across this back with ADO and classic asp, the answer i got was: performance. if you do a straight
Select * from tablename
and pass that in as an sql command/text you will get a noticeable performance increase with the
Where 1=1
added, it was a visible difference. something to do with table headers being returned as soon as the first condition is met, or some other craziness, anyway, it did speed things up.
You can use .eq()
and .after()
like this:
$('#my_table > tbody > tr').eq(i-1).after(html);
The indexes are 0 based, so to be the 4th row, you need i-1
, since .eq(3)
would be the 4th row, you need to go back to the 3rd row (2
) and insert .after()
that.
I recently came across Python 3 interpreter at CompileOnline.
As mentioned in some of the comments, ReactDOM.render
no longer returns the component instance. You can pass a ref
callback in when rendering the root of the component to get the instance, like so:
// React code (jsx)
function MyWidget(el, refCb) {
ReactDOM.render(<MyComponent ref={refCb} />, el);
}
export default MyWidget;
and:
// vanilla javascript code
var global_widget_instance;
MyApp.MyWidget(document.getElementById('my_container'), function(widget) {
global_widget_instance = widget;
});
global_widget_instance.myCoolMethod();
string str = intVar.ToString();
In some conditions, you do not have to use ToString()
string str = "hi " + intVar;
If you want numbers to be uniformly distributed over the range, you should break your range up into a number of equal sections that represent the number of points you need. Then get a random number with a min/max for each section.
As another note, you should probably not use rand()
as it's not very good at actually generating random numbers. I don't know what platform you're running on, but there is probably a better function you can call like random()
.

They are identical. JPG is simply a holdover from the days of DOS when file extensions were required to be 3 characters long. You can find out more information about the JPEG standard here. A question very similar to this one was asked over at SuperUser, where the accepted answer should give you some more detailed information.
It seems that you need to wait for the page to be reloaded before clicking on the "Add" button. In this case you could wait for the "Add Item" element to become stale before clicking on the reloaded element:
WebDriverWait wait = new WebDriverWait(driver, 20);
By addItem = By.xpath("//input[.='Add Item']");
// get the "Add Item" element
WebElement element = wait.until(ExpectedConditions.presenceOfElementLocated(addItem));
//trigger the reaload of the page
driver.findElement(By.id("...")).click();
// wait the element "Add Item" to become stale
wait.until(ExpectedConditions.stalenessOf(element));
// click on "Add Item" once the page is reloaded
wait.until(ExpectedConditions.presenceOfElementLocated(addItem)).click();
Moreover, mousemove
events are not triggered if you perform drag'n'drop over a browser window.
To track mouse coordinates during drag'n'drop you should attach handler for document.ondragover
event and use it's originalEvent property.
Example:
var globalDragOver = function (e)
{
var original = e.originalEvent;
if (original)
{
window.x = original.pageX;
window.y = original.pageY;
}
}
Another solution is to migrate the database to e.g 2012 when you "export" the DB from e.g. Sql Server manager 2014. This is done in menu Tasks-> generate scripts when right-click on DB. Just follow this instruction:
https://www.mssqltips.com/sqlservertip/2810/how-to-migrate-a-sql-server-database-to-a-lower-version/
It generates an scripts with everything and then in your SQL server manager e.g. 2012 run the script as specified in the instruction. I have performed the test with success.
function fnGetRandomColour(iDarkLuma, iLightLuma)
{
for (var i=0;i<20;i++)
{
var sColour = ('ffffff' + Math.floor(Math.random() * 0xFFFFFF).toString(16)).substr(-6);
var rgb = parseInt(sColour, 16); // convert rrggbb to decimal
var r = (rgb >> 16) & 0xff; // extract red
var g = (rgb >> 8) & 0xff; // extract green
var b = (rgb >> 0) & 0xff; // extract blue
var iLuma = 0.2126 * r + 0.7152 * g + 0.0722 * b; // per ITU-R BT.709
if (iLuma > iDarkLuma && iLuma < iLightLuma) return sColour;
}
return sColour;
}
For pastel, pass in higher luma dark/light integers - ie fnGetRandomColour(120, 250)

This is what I did:
Basically, think of the detached HEAD
as a new branch, without name. You can commit into this branch just like any other branch. Once you are done committing, you want to push it to the remote.
So the first thing you need to do is give this detached HEAD
a name. You can easily do it like, while being on this detached HEAD
:
git checkout -b some-new-branch
Now you can push it to remote like any other branch.
In my case, I also wanted to fast-forward this branch to master along with the commits I made in the detached HEAD
(now some-new-branch
). All I did was
git checkout master
git pull # To make sure my local copy of master is up to date
git checkout some-new-branch
git merge master // This added current state of master to my changes
Of course, I merged it later to master
.
That's about it.
MySQL version: 5.5.28-0ubuntu0.12.04.2-log
I was also under the impression that JOIN is always better than a sub-query in MySQL, but EXPLAIN is a better way to make a judgment. Here is an example where sub queries work better than JOINs.
Here is my query with 3 sub-queries:
EXPLAIN SELECT vrl.list_id,vrl.ontology_id,vrl.position,l.name AS list_name, vrlih.position AS previous_position, vrl.moved_date
FROM `vote-ranked-listory` vrl
INNER JOIN lists l ON l.list_id = vrl.list_id
INNER JOIN `vote-ranked-list-item-history` vrlih ON vrl.list_id = vrlih.list_id AND vrl.ontology_id=vrlih.ontology_id AND vrlih.type='PREVIOUS_POSITION'
INNER JOIN list_burial_state lbs ON lbs.list_id = vrl.list_id AND lbs.burial_score < 0.5
WHERE vrl.position <= 15 AND l.status='ACTIVE' AND l.is_public=1 AND vrl.ontology_id < 1000000000
AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=43) IS NULL
AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=55) IS NULL
AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=246403) IS NOT NULL
ORDER BY vrl.moved_date DESC LIMIT 200;
EXPLAIN shows:
+----+--------------------+----------+--------+-----------------------------------------------------+--------------+---------+-------------------------------------------------+------+--------------------------+

The same query with JOINs is:
EXPLAIN SELECT vrl.list_id,vrl.ontology_id,vrl.position,l.name AS list_name, vrlih.position AS previous_position, vrl.moved_date
FROM `vote-ranked-listory` vrl
INNER JOIN lists l ON l.list_id = vrl.list_id
INNER JOIN `vote-ranked-list-item-history` vrlih ON vrl.list_id = vrlih.list_id AND vrl.ontology_id=vrlih.ontology_id AND vrlih.type='PREVIOUS_POSITION'
INNER JOIN list_burial_state lbs ON lbs.list_id = vrl.list_id AND lbs.burial_score < 0.5
LEFT JOIN list_tag lt1 ON lt1.list_id = vrl.list_id AND lt1.tag_id = 43
LEFT JOIN list_tag lt2 ON lt2.list_id = vrl.list_id AND lt2.tag_id = 55
INNER JOIN list_tag lt3 ON lt3.list_id = vrl.list_id AND lt3.tag_id = 246403
WHERE vrl.position <= 15 AND l.status='ACTIVE' AND l.is_public=1 AND vrl.ontology_id < 1000000000
AND lt1.list_id IS NULL AND lt2.tag_id IS NULL
ORDER BY vrl.moved_date DESC LIMIT 200;
and the output is:
+----+-------------+-------+--------+-----------------------------------------------------+--------------+---------+---------------------------------------------+------+----------------------------------------------+

A comparison of the rows
column tells the difference and the query with JOINs is using Using temporary; Using filesort
.
Of course when I run both the queries, the first one is done in 0.02 secs, the second one does not complete even after 1 min, so EXPLAIN explained these queries properly.
If I do not have the INNER JOIN on the list_tag
table i.e. if I remove
AND (SELECT list_id FROM list_tag WHERE list_id=l.list_id AND tag_id=246403) IS NOT NULL
from the first query and correspondingly:
INNER JOIN list_tag lt3 ON lt3.list_id = vrl.list_id AND lt3.tag_id = 246403
from the second query, then EXPLAIN returns the same number of rows for both queries and both these queries run equally fast.
Chr(10)
is the Line Feed character and Chr(13)
is the Carriage Return character.
You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.
Historically, Line Feed would move down a line but not return to column 1:
This
is
a
test.
Similarly Carriage Return would return to column 1 but not move down a line:
This
is
a
test.
Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.
Looking at your Erlang implementation. The timing has included the start up of the entire virtual machine, running your program and halting the virtual machine. Am pretty sure that setting up and halting the erlang vm takes some time.
If the timing was done within the erlang virtual machine itself, results would be different as in that case we would have the actual time for only the program in question. Otherwise, i believe that the total time taken by the process of starting and loading of the Erlang Vm plus that of halting it (as you put it in your program) are all included in the total time which the method you are using to time the program is outputting. Consider using the erlang timing itself which we use when we want to time our programs within the virtual machine itself
timer:tc/1 or timer:tc/2 or timer:tc/3
. In this way, the results from erlang will exclude the time taken to start and stop/kill/halt the virtual machine. That is my reasoning there, think about it, and then try your bench mark again.
I actually suggest that we try to time the program (for languages that have a runtime), within the runtime of those languages in order to get a precise value. C for example has no overhead of starting and shutting down a runtime system as does Erlang, Python and Haskell (98% sure of this - i stand correction). So (based on this reasoning) i conclude by saying that this benchmark wasnot precise /fair enough for languages running on top of a runtime system. Lets do it again with these changes.
EDIT: besides even if all the languages had runtime systems, the overhead of starting each and halting it would differ. so i suggest we time from within the runtime systems (for the languages for which this applies). The Erlang VM is known to have considerable overhead at start up!
A more elegant solution could be:
def progressBar(current, total, barLength = 20):
percent = float(current) * 100 / total
arrow = '-' * int(percent/100 * barLength - 1) + '>'
spaces = ' ' * (barLength - len(arrow))
print('Progress: [%s%s] %d %%' % (arrow, spaces, percent), end='\r')
call this function with value
and endvalue
, result should be
Progress: [-------------> ] 69 %
Note: Python 2.x version here.
The following shows an example of a shared class library shared.[h,cpp] and a main.cpp module using the library. It's a very simple example and the makefile could be made much better. But it works and may help you:
shared.h defines the class:
class myclass {
int myx;
public:
myclass() { myx=0; }
void setx(int newx);
int getx();
};
shared.cpp defines the getx/setx functions:
#include "shared.h"
void myclass::setx(int newx) { myx = newx; }
int myclass::getx() { return myx; }
main.cpp uses the class,
#include <iostream>
#include "shared.h"
using namespace std;
int main(int argc, char *argv[])
{
myclass m;
cout << m.getx() << endl;
m.setx(10);
cout << m.getx() << endl;
}
and the makefile that generates libshared.so and links main with the shared library:
main: libshared.so main.o
$(CXX) -o main main.o -L. -lshared
libshared.so: shared.cpp
$(CXX) -fPIC -c shared.cpp -o shared.o
$(CXX) -shared -Wl,-soname,libshared.so -o libshared.so shared.o
clean:
$rm *.o *.so
To actual run 'main' and link with libshared.so you will probably need to specify the load path (or put it in /usr/local/lib or similar).
The following specifies the current directory as the search path for libraries and runs main (bash syntax):
export LD_LIBRARY_PATH=.
./main
To see that the program is linked with libshared.so you can try ldd:
LD_LIBRARY_PATH=. ldd main
Prints on my machine:
~/prj/test/shared$ LD_LIBRARY_PATH=. ldd main
linux-gate.so.1 => (0xb7f88000)
libshared.so => ./libshared.so (0xb7f85000)

I use Log.d method also please import import android.util.Log;
Log.d("TAG", "Message");
But please keep in mind that, when you want to see the debug messages then don't use Run As rather use "Debug As" then select Android Application. Otherwise you'll not see the debug messages.
if you're developing flutter packages, please add package param after image path like this:
AssetImage('images/heart.png', package: 'my_icons') // my_icons is your plugin name, in flutter plugin is also a package.
Here is the link from flutter docs https://flutter.dev/assets-and-images/#from-packages
If you have multiple inputs as text in a form or a table that you need to iterate through, I did this:
var $list = $("#tableOrForm :input[type='text']");
$list.each(function(){
// Go on with your code.
});
What I did was I checked each input to see if the type is set to "text", then it'll grab that element and store it in the jQuery list. Then, it would iterate through that list. You can set a temp variable for the current iteration like this:
var $currentItem = $(this);
This will set the current item to the current iteration of your for each loop. Then you can do whatever you want with the temp variable.
Hope this helps anyone!
ipta = raw_input("Word: ") ## asks for input
words = [] ## creates list
while ipta: ## while loop to ask for input and append in list
words.append(ipta)
ipta = raw_input("Word: ")
words.append(ipta)
#Create a set, sets do not have repeats
unique_words = set(words)
print "There are " + str(len(unique_words)) + " unique words!"
We can do this by setting out variable of System class in the following way
System.setOut(new PrintStream(new FileOutputStream("Path to output file"))). Also You need to close or flush 'out'(System.out.close() or System.out.flush()) variable so that you don't end up missing some output.

There is no version 1.3.0
for rope
. 1.3.0
refers to the package cached-property
. The highest available version of rope
is 0.9.4
.
You can install different versions with conda install package=version
. But in this case there is only one version of rope
so you don't need that.
The reason you see the cached-property
in this listing is because it contains the string "rope"
: "cached-p rope erty"
py35_0
means that you need python version 3.5
for this specific version. If you only have python3.4
and the package is only for version 3.5
you cannot install it with conda.
I am not quite sure on the defaults
either. It should be an indication that this package is inside the default conda channel.
All values of column A that are not present in column B will have a red background. Hope that it helps as starting point.
Sub highlight_missings()
Dim i As Long, lastA As Long, lastB As Long
Dim compare As Variant
Range("A:A").ClearFormats
lastA = Range("A65536").End(xlUp).Row
lastB = Range("B65536").End(xlUp).Row
For i = 2 To lastA
compare = Application.Match(Range("a" & i), Range("B2:B" & lastB), 0)
If IsError(compare) Then
Range("A" & i).Interior.ColorIndex = 3
End If
Next i
End Sub
you can use ps
.
e.g. having python process with two busy threads on dual core CPU:
$ ps -p 29492 -L -o pid,tid,psr,pcpu
PID TID PSR %CPU
29492 29492 1 0.0
29492 29493 1 48.7
29492 29494 1 51.9
(PSR is CPU id the thread is currently assigned to)
you see that the threads are running on the same cpu core (because of GIL)
running the same python script in jython, we see, that the script is utilizing both cores (and there are many other service or whatever threads, which are almost idle):
$ ps -p 28671 -L -o pid,tid,psr,pcpu
PID TID PSR %CPU
28671 28671 1 0.0
28671 28672 0 4.4
28671 28673 0 0.6
28671 28674 0 0.5
28671 28675 0 2.3
28671 28676 0 0.0
28671 28677 1 0.0
28671 28678 1 0.0
28671 28679 0 4.6
28671 28680 0 4.4
28671 28681 1 0.0
28671 28682 1 0.0
28671 28721 1 0.0
28671 28729 0 88.6
28671 28730 1 88.5
you can process the output and calculate the total CPU for each CPU core.
Unfortunately, this approach does not seem to be 100% reliable, sometimes i see that in the first case, the two working threads are reported to be separated to each CPU core, or in the latter case, the two threads are reported to be on the same core..
The error says it all actually. Your configuration tells Nginx to listen on port 80 (HTTP) and use SSL. When you point your browser to http://localhost
, it tries to connect via HTTP. Since Nginx expects SSL, it complains with the error.
The workaround is very simple. You need two server
sections:
server {
listen 80;
// other directives...
}
server {
listen 443;
ssl on;
// SSL directives...
// other directives...
}
I figured out what it was! When I cleared the fields using the each() method, it also cleared the hidden field which the php needed to run:
if ($_POST['action'] == 'addRunner')
I used the :not() on the selection to stop it from clearing the hidden field.
For Your JSON response you should parse that response for expected results
For Instance: parsed_response = JSON.parse(response.body)
You can check other variables which is included in response like
expect(parsed_response["success"]).to eq(true)
expect(parsed_response["flashcard"]).to eq("flashcard expected value")
expect(parsed_response["lesson"]).to eq("lesson expected value")
expect(subject["status_code"]).to eq(201)
I prefer also check keys of JSON response, For Example:
expect(body_as_json.keys).to match_array(["success", "lesson","status_code", "flashcard"])
Here, We can use should matchers For expected results in Rspec
Here is another way with leading '0' for all of them.
$secCount = 10000;
$hours = str_pad(floor($secCount / (60*60)), 2, '0', STR_PAD_LEFT);
$minutes = str_pad(floor(($secCount - $hours*60*60)/60), 2, '0', STR_PAD_LEFT);
$seconds = str_pad(floor($secCount - ($hours*60*60 + $minutes*60)), 2, '0', STR_PAD_LEFT);
It is an adaptation from the answer of Flaxious.
Simplification from the above Andrew's answer leads to this key theme to generate the half border.

axis.line = element_line(color='black'))
In WCF serive project this issue may be due to Reference of System.Web.Mvc.dll 's different version or may be any other DLL's different version issue. So this may be compatibility issue of DLL's different version
When I use
System.Web.Mvc.dll version 5.2.2.0 -> it thorows the Error The content type text/html; charset=utf-8 of the response message
but when I use
System.Web.Mvc.dll version 4.0.0.0 or lower -> That's works fine in my project and not have an Error.
I don't know the reason of this different version of DLL's issue but when I change the DLL's verison which is compatible with your WCF Project than it works fine.
This Error even generate when you add reference of other Project in your WCF Project and this reference project has different version of System.Web.Mvc DLL or could be any other DLL.
Casting will ignore anything after the decimal point, so 8.6 becomes 8.
Convert.ToInt32(8.6)
is the safe way to ensure your double gets rounded to the nearest integer, in this case 9.
I got the same error but it was due to me not creating a default constructor. If you haven't already tried that, create the default constructor like this:
public TestClass() {
}
You know that Maven is based on the Convention over Configuration pardigm? so you shouldn't configure things which are the defaults.
All that stuff represents the default in Maven. So best practice is don't define it it's already done.

<testOutputDirectory>target/test-classes</testOutputDirectory>

Why not use PHP! It's all server side:
<?php print file_get_contents("http://foo.com")?>
If you own both sites, you may need to ok this transaction with full declaration of headers at the server end. Works beautifully.
If you have a list with 53 items, the last one is thelist[52]
because indexing starts at 0.
IndexError
IndexError
The IndexError
is raised when attempting to retrieve an index from a sequence (e.g. list
, tuple
), and the index isn’t found in the sequence. The Python documentation defines when this exception is raised:
Raised when a sequence subscript is out of range. (Source)
Here’s an example that raises the IndexError
:
test = list(range(53))
test[53]
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
<ipython-input-6-7879607f7f36> in <module>
1 test = list(range(53))
----> 2 test[53]
IndexError: list index out of range
The error message line for an IndexError
doesn’t provide great information. See that there is a sequence reference that is out of range and what the type of the sequence is, a list
in this case. That information, combined with the rest of the traceback, is usually enough to help quickly identify how to fix the issue.

I'm not amazing at PHP, but I think this is what you do:
$password = md5($password)
and $password
would be the $_POST['password']
or whatever
I found 3 ways to implement this:
C# class:
public class AddressInfo {
public string Address1 { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string ZipCode { get; set; }
public string Country { get; set; }
}
Action:
[HttpPost]
public ActionResult Check(AddressInfo addressInfo)
{
return Json(new { success = true });
}
JavaScript you can do it three ways:
1) Query String:
$.ajax({
url: '/en/Home/Check',
data: $('#form').serialize(),
type: 'POST',
});
Data here is a string.
"Address1=blah&Address2=blah&City=blah&State=blah&ZipCode=blah&Country=blah"
2) Object Array:
$.ajax({
url: '/en/Home/Check',
data: $('#form').serializeArray(),
type: 'POST',
});
Data here is an array of key/value pairs :
=[{name: 'Address1', value: 'blah'}, {name: 'Address2', value: 'blah'}, {name: 'City', value: 'blah'}, {name: 'State', value: 'blah'}, {name: 'ZipCode', value: 'blah'}, {name: 'Country', value: 'blah'}]
3) JSON:
$.ajax({
url: '/en/Home/Check',
data: JSON.stringify({ addressInfo:{//missing brackets
Address1: $('#address1').val(),
Address2: $('#address2').val(),
City: $('#City').val(),
State: $('#State').val(),
ZipCode: $('#ZipCode').val()}}),
type: 'POST',
contentType: 'application/json; charset=utf-8'
});
Data here is a serialized JSON string. Note that the name has to match the parameter name in the server!!
='{"addressInfo":{"Address1":"blah","Address2":"blah","City":"blah","State":"blah", "ZipCode", "blah", "Country", "blah"}}'
Use pandas and the json library:
import pandas as pd
import json
filepath = "inputfile.csv"
output_path = "outputfile.json"
df = pd.read_csv(filepath)
# Create a multiline json
json_list = json.loads(df.to_json(orient = "records"))
with open(output_path, 'w') as f:
for item in json_list:
f.write("%s\n" % item)
I think you have a couple of options here.
you could store the last Exception in the Session and retrieve it from your custom error page; or you could just redirect to your custom error page within the Application_error event. If you choose the latter, you want to make sure you use the Server.Transfer method.
[[Prototype]] :
[[Prototype]] is an internal hidden property of objects in JS and it is a reference to another object. Every object at the time of creation receives a non-null value for [[Prototype]]. Remember [[Get]] operation is invoked when we reference a property on an object like, myObject.a. If the object itself has a property, a on it then that property will be used.
let myObject= {
a: 2
};
console.log(myObject.a); // 2
But if the object itself directly does not have the requested property then [[Get]] operation will proceed to follow the [[Prototype]] link of the object. This process will continue until either a matching property name is found or the [[Prototype]] chain ends(at the built-in Object.prototype). If no matching property is found then undefined will be returned. Object.create(specifiedObject) creates an object with the [[Prototype]] linkage to the specified object.
let anotherObject= {
a: 2
};
// create an object linked to anotherObject
let myObject= Object.create(anotherObject);
console.log(myObject.a); // 2
Both for..in loop and in operator use [[Prototype]] chain lookup process. So if we use for..in loop to iterate over the properties of an object then all the enumerable properties which can be reached via that object's [[Prototype]] chain also will be enumerated along with the enumerable properties of the object itself. And when using in operator to test for the existence of a property on an object then in operator will check all the properties via [[Prototype]] linkage of the object regardless of their enumerability.
// for..in loop uses [[Prototype]] chain lookup process
let anotherObject= {
a: 2
};
let myObject= Object.create(anotherObject);
for(let k in myObject) {
console.log("found: " + k); // found: a
}
// in operator uses [[Prototype]] chain lookup process
console.log("a" in myObject); // true
.prototype :
.prototype is a property of functions in JS and it refers to an object having constructor property which stores all the properties(and methods) of the function object.
let foo= function(){}
console.log(foo.prototype);
// returns {constructor: f} object which now contains all the default properties
foo.id= "Walter White";
foo.job= "teacher";
console.log(foo.prototype);
// returns {constructor: f} object which now contains all the default properties and 2 more properties that we added to the fn object
/*
{constructor: f}
constructor: f()
id: "Walter White"
job: "teacher"
arguments: null
caller: null
length: 0
name: "foo"
prototype: {constructor: f}
__proto__: f()
[[FunctionLocation]]: VM789:1
[[Scopes]]: Scopes[2]
__proto__: Object
*/
But normal objects in JS does not have .prototype property. We know Object.prototype is the root object of all the objects in JS. So clearly Object is a function i.e. typeof Object === "function" . That means we also can create object from the Object function like, let myObj= new Object( ). Similarly Array, Function are also functions so we can use Array.prototype, Function.prototype to store all the generic properties of arrays and functions. So we can say JS is built on functions.
{}.prototype; // SyntaxError: Unexpected token '.'
(function(){}).prototype; // {constructor: f}
Also using new operator if we create objects from a function then internal hidden [[Prototype]] property of those newly created objects will point to the object referenced by the .prototype property of the original function. In the below code, we have created an object, a from a fn, Letter and added 2 properties one to the fn object and another to the prototype object of the fn. Now if we try to access both of the properties on the newly created object, a then we only will be able to access the property added to the prototype object of the function. This is because the prototype object of the function is now on the [[Prototype]] chain of the newly created object, a.
let Letter= function(){}
let a= new Letter();
Letter.from= "Albuquerque";
Letter.prototype.to= "New Hampshire";
console.log(a.from); // undefined
console.log(a.to); // New Hampshire
.__proto__:
.__proto__
is a property of objects in JS and it references the another object in the [[Prototype]] chain. We know [[Prototype]] is an internal hidden property of objects in JS and it references another object in the [[Prototype]] chain. We can get or set the object referred by the internal [[Prototype]] property in 2 ways
Object.getPrototypeOf(obj) / Object.setPrototypeOf(obj)
obj.__proto__
We can traverse the [[Prototype]] chain using: .__proto__.__proto__. .
. Along with .constructor, .toString( ), .isPrototypeOf( ) our dunder proto property (__proto__
) actually exists on the built-in Object.prototype root object, but available on any particular object. Our .__proto__
is actually a getter/setter. Implementation of .__proto__
in Object.prototype is as below :
Object.defineProperty(Object.prototype, "__proto__", {
get: function() {
return Object.getPrototypeOf(this);
},
set: function(o) {
Object.setPrototypeOf(this, o);
return o;
}
});
To retrieve the value of obj.__proto__
is like calling, obj.__proto__()
which actually returns the calling of the getter fn, Object.getPrototypeOf(obj)
which exists on Object.prototype object. Although .__proto__
is a settable property but we should not change [[Prototype]] of an already existing object because of performance issues.
Using new operator if we create objects from a function then internal hidden [[Prototype]] property of those newly created objects will point to the object referenced by the .prototype property of the original function. Using .__proto__
property we can access the other object referenced by internal hidden [[Prototype]] property of the object. But __proto__
is not the same as [[Prototype]] rather a getter/setter for it. Consider below code :
let Letter= function() {}
let a= new Letter();
let b= new Letter();
let z= new Letter();
// output in console
a.__proto__ === Letter.prototype; // true
b.__proto__ === Letter.prototype; // true
z.__proto__ === Letter.prototype; // true
Letter.__proto__ === Function.prototype; // true
Function.prototype.__proto__ === Object.prototype; // true
Letter.prototype.__proto__ === Object.prototype; // true
Basically it's designing your cell, The cellforrowatindexpath is called for each cell and the cell number is found by indexpath.row and section number by indexpath.section . Here you can use a label, button or textfied image anything that you want which are updated for all rows in the table. Answer for second question In cell for row at index path use an if statement
In Objective C
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(tableView == firstTableView)
{
//code for first table view
[cell.contentView addSubview: someView];
}
if(tableview == secondTableView)
{
//code for secondTableView
[cell.contentView addSubview: someView];
}
return cell;
}
In Swift 3.0
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
if(tableView == firstTableView) {
//code for first table view
}
if(tableview == secondTableView) {
//code for secondTableView
}
return cell
}
According to other answers I am adding the parallel stages scenario:
pipeline {
agent any
stages {
stage('some parallel stage') {
parallel {
stage('parallel stage 1') {
when {
expression { ENV == "something" }
}
steps {
echo 'something'
}
}
stage('parallel stage 2') {
steps {
echo 'something'
}
}
}
}
}
}
table_ex
id default nextval('table_id_seq'::regclass),
camp1 varchar
camp2 varchar
INSERT INTO table_ex(camp1,camp2) VALUES ('xxx','123') RETURNING id
Just to complete the above answer.
Manifest file is located inside jar at META-INF\MANIFEST.MF

You can examine jar's contents in any archiver that supports zip.
I hope this will help
select distinct city from station where lower(substring(city,1,1)) in ('a','e','i','o','u') and lower(substring(city,length(city),length(city))) in ('a','e','i','o','u') ;
If you need to update the value in a particular table:
UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');
where
TABLE-NAME - The name of the table being updated
COLUMN-NAME - The name of the column being updated
STRING-TO-REPLACE - The value to replace
REPLACEMENT-STRING - The replacement
Another yet simple solution is to paste these line into the build.gradle file
dependencies {
//import of gridlayout
compile 'com.android.support:gridlayout-v7:19.0.0'
compile 'com.android.support:appcompat-v7:+'
}
You can easy change collation in Microsoft SQL Server Management studio.
.scroll {
width: 200px; height: 400px;
overflow: auto;

Here the method that I usually use and works for me (both for 32 bit and 64 bit applications; ie_emulation can be anyone documented here: Internet Feature Controls (B..C), Browser Emulation):
[STAThread]
static void Main()
{
if (!mutex.WaitOne(TimeSpan.FromSeconds(2), false))
{
// Another application instance is running
return;
}
try
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
var targetApplication = Process.GetCurrentProcess().ProcessName + ".exe";
int ie_emulation = 10000;
try
{
string tmp = Properties.Settings.Default.ie_emulation;
ie_emulation = int.Parse(tmp);
}
catch { }
SetIEVersioneKeyforWebBrowserControl(targetApplication, ie_emulation);
m_webLoader = new FormMain();
Application.Run(m_webLoader);
}
finally
{
mutex.ReleaseMutex();
}
}
private static void SetIEVersioneKeyforWebBrowserControl(string appName, int ieval)
{
RegistryKey Regkey = null;
try
{
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
// If the path is not correct or
// if user haven't privileges to access the registry
if (Regkey == null)
{
YukLoggerObj.logWarnMsg("Application FEATURE_BROWSER_EMULATION Failed - Registry key Not found");
return;
}
string FindAppkey = Convert.ToString(Regkey.GetValue(appName));
// Check if key is already present
if (FindAppkey == "" + ieval)
{
YukLoggerObj.logInfoMsg("Application FEATURE_BROWSER_EMULATION already set to " + ieval);
Regkey.Close();
return;
}
// If a key is not present or different from desired, add/modify the key, key value
Regkey.SetValue(appName, unchecked((int)ieval), RegistryValueKind.DWord);
// Check for the key after adding
FindAppkey = Convert.ToString(Regkey.GetValue(appName));
if (FindAppkey == "" + ieval)
YukLoggerObj.logInfoMsg("Application FEATURE_BROWSER_EMULATION changed to " + ieval + "; changes will be visible at application restart");

New Thread
and AsyncTask solutions have been explained already.
AsyncTask
should ideally be used for short operations. Normal Thread
is not preferable for Android.
Have a look at alternate solution using HandlerThread and Handler
HandlerThread
Handy class for starting a new thread that has a looper. The looper can then be used to create handler classes. Note that
start()
must still be called.
Handler:
A Handler allows you to send and process Message and Runnable objects associated with a thread's MessageQueue. Each Handler instance is associated with a single thread and that thread's message queue. When you create a new Handler, it is bound to the thread / message queue of the thread that is creating it -- from that point on, it will deliver messages and runnables to that message queue and execute them as they come out of the message queue.
Solution:
Create HandlerThread
Call start()
on HandlerThread
Create Handler
by getting Looper
from HanlerThread
Embed your Network operation related code in Runnable
object
Submit Runnable
task to Handler
Sample code snippet, which address NetworkOnMainThreadException
HandlerThread handlerThread = new HandlerThread("URLConnection");
handlerThread.start();
handler mainHandler = new Handler(handlerThread.getLooper());
Runnable myRunnable = new Runnable() {
@Override
public void run() {
try {
Log.d("Ravi", "Before IO call");
URL page = new URL("http://www.google.com");
StringBuffer text = new StringBuffer();
HttpURLConnection conn = (HttpURLConnection) page.openConnection();
conn.connect();
InputStreamReader in = new InputStreamReader((InputStream) conn.getContent());
BufferedReader buff = new BufferedReader(in);
String line;
while ( (line = buff.readLine()) != null) {
text.append(line + "\n");
}
Log.d("Ravi", "After IO call");
Log.d("Ravi",text.toString());
}catch( Exception err){
err.printStackTrace();
}
}
};
mainHandler.post(myRunnable);
Pros of using this approach:
Thread/AsyncTask
for each network operation is expensive. The Thread/AsyncTask
will be destroyed and re-created for next Network operations. But with Handler
and HandlerThread
approach, you can submit many network operations (as Runnable tasks) to single HandlerThread
by using Handler
. I strongly recommend using Java generics to specify what type of object is in that List, ie. List<Car>
. If you have Cars and Trucks you can use a common superclass/interface like this List<Vehicle>
.
However, you can use Spring's ReflectionUtils to make fields accessible, even if they are private like the below runnable example:
List<Object> list = new ArrayList<Object>();
list.add("some value");
list.add(3);
for(Object obj : list)
{
Class<?> clazz = obj.getClass();
Field field = org.springframework.util.ReflectionUtils.findField(clazz, "value");
org.springframework.util.ReflectionUtils.makeAccessible(field);
System.out.println("value=" + field.get(obj));
}
Running this has an output of:
value=[C@1b67f74
value=3
Below code for an uploading a single file at a time. This is correct and perfect to upload a single file. Read all commented instructions and follow the code. Definitely, it is worked.
public function upload_file() {
***// Upload folder location***
$config['upload_path'] = './public/upload/';
***// Allowed file type***
$config['allowed_types'] = 'jpg|jpeg|png|pdf';
***// Max size, i will set 2MB***
$config['max_size'] = '2024';
$config['max_width'] = '1024';
$config['max_height'] = '768';
***// load upload library***
$this->load->library('upload', $config);
***// do_upload is the method, to send the particular image and file on that
// particular
// location that is detail in $config['upload_path'].
// In bracks will set name upload, here you need to set input name attribute
// value.***
if($this->upload->do_upload('upload')) {
$data = $this->upload->data();
$post['upload'] = $data['file_name'];
} else {
$error = array('error' => $this->upload->display_errors());
}
}
Don't forget that an input field must be visible first, thereafter you're able to focus it.
$("#elementid").show();
$("#elementid input[type=text]").focus();
Firefox 29 currently adds support for number elements, so here's a snippet for hiding the spinners in webkit and moz based browsers:
input[type='number'] {_x000D_
-moz-appearance:textfield;_x000D_
}_x000D_
_x000D_
input::-webkit-outer-spin-button,_x000D_
input::-webkit-inner-spin-button {_x000D_
-webkit-appearance: none;_x000D_
}
_x000D_
<input id="test" type="number">
_x000D_
jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div
(or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.
In addition to already posted examples, here is another approach using express-async-wrap and asynchronous functions (ES2017).
Router
router.put('/:id/settings/profile', wrap(async function (request, response, next) {
const username = request.body.username
const email = request.body.email
const userWithEmail = await userService.findUserByEmail(email)
if (userWithEmail) {
return response.status(409).send({message: 'Email is already taken.'})
}
const userWithUsername = await userService.findUserByUsername(username)
if (userWithUsername) {
return response.status(409).send({message: 'Username is already taken.'})
}
const user = await userService.updateProfileSettings(userId, username, email)
return response.status(200).json({user: user})
}))
UserService
async function updateProfileSettings (userId, username, email) {
try {
return User.findOneAndUpdate({'_id': userId}, {
$set: {
'username': username,
'auth.email': email
}
}, {new: true})
} catch (error) {
throw new Error(`Unable to update user with id "${userId}".`)
}
}
async function findUserByEmail (email) {
try {
return User.findOne({'auth.email': email.toLowerCase()})
} catch (error) {
throw new Error(`Unable to connect to the database.`)
}
}
async function findUserByUsername (username) {
try {
return User.findOne({'username': username})
} catch (error) {
throw new Error(`Unable to connect to the database.`)
}
}
// other methods
export default {
updateProfileSettings,
findUserByEmail,
findUserByUsername,
}
Resources
To quote the help page (try ?integer
), bolded portion mine:
Integer vectors exist so that data can be passed to C or Fortran code which expects them, and so that (small) integer data can be represented exactly and compactly.
Note that current implementations of R use 32-bit integers for integer vectors, so the range of representable integers is restricted to about +/-2*10^9: doubles can hold much larger integers exactly.
Like the help page says, R's integer
s are signed 32-bit numbers so can hold between -2147483648 and +2147483647 and take up 4 bytes.
R's numeric
is identical to an 64-bit double
conforming to the IEEE 754 standard. R has no single precision data type. (source: help pages of numeric
and double
). A double can store all integers between -2^53 and 2^53 exactly without losing precision.
We can see the data type sizes, including the overhead of a vector (source):
> object.size(1:1000)
4040 bytes
> object.size(as.numeric(1:1000))
8040 bytes
Although Chang's answer explains how to plot multiple times on the same figure, in this case you might be better off in this case using a groupby
and unstack
ing:
(Assuming you have this in dataframe, with datetime index already)
In [1]: df
Out[1]:
value
datetime
2010-01-01 1
2010-02-01 1
2009-01-01 1
# create additional month and year columns for convenience
df['Month'] = map(lambda x: x.month, df.index)
df['Year'] = map(lambda x: x.year, df.index)
In [5]: df.groupby(['Month','Year']).mean().unstack()
Out[5]:
value
Year 2009 2010
Month
1 1 1
2 NaN 1
Now it's easy to plot (each year as a separate line):
df.groupby(['Month','Year']).mean().unstack().plot()
An XPath solution is to use:
string-length((//div[@class='contest'])[$k])
where $k should be substituted by a number.
This evaluates to the string length of the $k-th (in document order) div
in the XML document that has a class
attribute with value 'contest'.
I don't see anyone mentioning that if you don't provide a message it will open nano for you (at least in Linux) where you can write multiple lines...
Only this is needed:
git commit
In xml:
<ImageView
android:clickable="true"
android:onClick="imageClick"
android:src="@drawable/myImage">
</ImageView>
In code
public class Test extends Activity {
........
........
public void imageClick(View view) {
//Implement image click function
}
How can I set the TTL/TTI/Eviction policy/XXX feature?
Directly through your cache provider. The cache abstraction is... well, an abstraction not a cache implementation
So, if you use EHCache, use EHCache's configuration to configure the TTL.
You could also use Guava's CacheBuilder to build a cache, and pass this cache's ConcurrentMap view to the setStore method of the ConcurrentMapCacheFactoryBean.
Use a ssh key.
Look at ssh-keygen
and ssh-copy-id
.
After that you can use an rsync
this way :
rsync -a --stats --progress --delete /home/path server:path
nobody has mentioned yet, in ASP.NET 4.0 there's new syntax to do this. instead of
<%= HttpUtility.HtmlEncode(unencoded) %>
you can simply do
<%: unencoded %>

When we save anything in Django admin two steps validation happens, on Django level and on Database level. We can't save text in a number field.
Database has data type NULL, it's nothing. When Django creates columns in the database it specifies that they can't be empty. And if you will try to save NULL you will get the database error.
Also on Django-Admin level, all fields are required by default, you can't save blank field, Django will throw you an error.
So, if you want to save blank field you need to allow it on Django and Database level. blank=True - will allow empty field in admin panel null=True - will allow saving NULL to the database column.
Yes, the Session object might be null, but only in certain circumstances, which you will only rarely run into:
If you only have code in pages, you won't run into this. Most of my ASP .NET code uses Session without checking for null repeatedly. It is, however, something to think about if you are developing an IHttpModule or otherwise is down in the grittier details of ASP .NET.
In answer to the comment: Whether or not session state is available depends on whether the AcquireRequestState event has run for the request. This is where the session state module does it's work by reading the session cookie and finding the appropiate set of session variables for you.
AcquireRequestState runs before control is handed to your Page. So if you are calling other functionality, including static classes, from your page, you should be fine.
If you have some classes doing initialization logic during startup, for example on the Application_Start event or by using a static constructor, Session state might not be available. It all boils down to whether there is a current request and AcquireRequestState has been run.
Also, should the client have disabled cookies, the Session object will still be available - but on the next request, the user will return with a new empty Session. This is because the client is given a Session statebag if he does not have one already. If the client does not transport the session cookie, we have no way of identifying the client as the same, so he will be handed a new session again and again.
The actual URL syntax is pretty complicated and not easy to represent in regex. Most of the simple-looking regexes out there will give many false negatives as well as false positives. See for amusement these efforts but even the end result is not good.
Plus these days you would generally want to allow IRI as well as old-school URI, so we can link to valid addresses like:
http://en.wikipedia.org/wiki/Þ
http://??.???/
I would go only for simple checks: does it start with a known-good method: name? Is it free of spaces and double-quotes? If so then hell, it's probably good enough.
You may use the class java.util.Random with method
char c = (char)(rnd.nextInt(128-32))+32
20x to get Bytes, which you interpret as ASCII. If you're fine with ASCII.
32 is the offset, from where the characters are printable in general.
Use:
SELECT *
FROM `table`
WHERE INSTR(`column`, '{$needle}') > 0
Reference:
This can also be done with the Image
class of the PIL library:
from PIL import Image
import numpy as np
im_frame = Image.open(path_to_file + 'file.png')
np_frame = np.array(im_frame.getdata())
Note: The .getdata()
might not be needed - np.array(im_frame)
should also work
Running the following commands solved this for me 1. python manage.py migrate 2. python manage.py makemigrations 3. python manage.py makemigrations appName
You are trying to fit a non-relational model into a relational database, I think you would be better served using a NoSQL database such as MongoDB. There is no predefined schema which fits in with your requirement of having no limitation to the number of fields (see the typical MongoDB collection example). Check out the MongoDB documentation to get an idea of how you'd query your documents, e.g.
db.mycollection.find(
{
name: 'sann'
}
)
You may use pattern
defined in the additional-methods.js
file. Note that this additional-methods.js file must be included after jQuery Validate dependency, then you can just use
$("#frm").validate({_x000D_

Textbox: {_x000D_
pattern: /^[a-zA-Z'.\s]{1,40}$/_x000D_
},_x000D_
},_x000D_
messages: {_x000D_
Textbox: {_x000D_
pattern: 'The Textbox string format is invalid'_x000D_
}_x000D_
}_x000D_
});

This is really easy using package lubridate. All you have to do is tell R what format your date is already in. It then converts it into the standard format
nzd$date <- dmy(nzd$date)
that's it.
Here are three ways to go with this problem :
from datetime import datetime
Now = datetime.now()
StartDate = datetime.strptime(str(Now.year) +'-01-01', '%Y-%m-%d')
NumberOfDays = (Now - StartDate)
print(NumberOfDays.days) # Starts at 0
print(datetime.now().timetuple().tm_yday) # Starts at 1
print(Now.strftime('%j')) # Starts at 1
Method names which are same as the class name are called constructors. Constructors do not have a return type. So correct as:
private Flow()
{
X = x;
Y = y;
}
Or rename the function as:
private void DoFlow()
{
X = x;
Y = y;
}
Though the whole code does not make any sense to me.
I am using this collection, when I worked in small elements collection.
Where elements lot, I think need use "Dictionary". My code:
NameValueCollection ProdIdes;
string prodId = _cfg.ProdIdes[key];
if (string.IsNullOrEmpty(prodId))
{
......
}
Or may be use this:
string prodId = _cfg.ProdIdes[key] !=null ? "found" : "not found";
Note that namespaces that are in the format of a valid Web URL don't necessarily need to be dereferenced i.e. you don't need to serve actual content at that URL. All that matters is that the namespace is globally unique.
MongoDB needs data directory to store data.
Default path is /data/db
When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx
permission to user.
If you want to change the path of your data directory then you should specify it while starting mongod server like,
mongod --dbpath /data/<path> --port <port no>
This should help you start your mongod server with custom path and port.
I came across a similar issue. However this issue was caused because of the way i designed the pages to bring the requests in. I placed all of my .js files as the last thing to be applied to the page, therefore they are at the end of my document. The .js files have all my functions include. The script manager seems that to be able to call this function it needs the js file already present with the function being called at the time of load. Hope this helps anyone else.
You can also use ls
with grep
or egrep
and put it in your profile as an alias:
ls -l | egrep -v '^d'
ls -l | grep -v '^d'
One way is to set the the div to position:absolute
and give it a top of 50px and bottom of 0px;
#div2
{
position:absolute;
bottom:0px;
top:50px
}
I was having this issue when using capistrano to deploy a rails app. The problem was that my user only had a jailed shell access in cpanel. Changing it to normal shell access fixed my problem.
I was facing the same issue, to solve it I have added the below entry in pom.xml
and performed a maven update
.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
openssl rsa -in f.pem -inform PEM -out f.der -outform DER
That would be:
b.rstrip('\n')
If you want to strip space from each and every line, you might consider instead:
a.read().splitlines()
This will give you a list of lines, without the line end characters.
INNER JOIN: Returns all rows when there is at least one match in BOTH tables
LEFT JOIN: Return all rows from the left table, and the matched rows from the right table
RIGHT JOIN: Return all rows from the right table, and the matched rows from the left table
FULL JOIN: Return all rows when there is a match in ONE of the tables
A new proposal to enhance SUDO for CygWin from GitHub in this thread, named TOUACExt:
Still in Pre-Beta, but seems to be working.
You can undo a rails generate
in the following ways:
rails destroy MODEL
rails destroy controller_name
check your casing, the name is typically stored in upper case
SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;
I guess this is essentially putting it in a string, but this avoids the rounding error:
import decimal
def display(x):
digits = 15
temp = str(decimal.Decimal(str(x) + '0' * digits))
return temp[:temp.find('.') + digits + 1]
If you want to mirror same content from source to destination, try following one.
function CopyFilesToFolder ($fromFolder, $toFolder) {
$childItems = Get-ChildItem $fromFolder
$childItems | ForEach-Object {
Copy-Item -Path $_.FullName -Destination $toFolder -Recurse -Force
}
}
Test:
CopyFilesToFolder "C:\temp\q" "c:\temp\w"
Chaining conditions creates long lines, which are discouraged by pep8. Using the .query method forces to use strings, which is powerful but unpythonic and not very dynamic.
Once each of the filters is in place, one approach is
import numpy as np
import functools
def conjunction(*conditions):
return functools.reduce(np.logical_and, conditions)
c_1 = data.col1 == True
c_2 = data.col2 < 64
c_3 = data.col3 != 4
data_filtered = data[conjunction(c1,c2,c3)]
np.logical operates on and is fast, but does not take more than two arguments, which is handled by functools.reduce.
Note that this still has some redundancies: a) shortcutting does not happen on a global level b) Each of the individual conditions runs on the whole initial data. Still, I expect this to be efficient enough for many applications and it is very readable.
You can also make a disjunction (wherein only one of the conditions needs to be true) by using np.logical_or
instead:
import numpy as np
import functools
def disjunction(*conditions):
return functools.reduce(np.logical_or, conditions)
c_1 = data.col1 == True
c_2 = data.col2 < 64
c_3 = data.col3 != 4
data_filtered = data[disjunction(c1,c2,c3)]
As for me, most elegant way is yield break
Here is a working plunkr with a filter and sortBy pipe. https://plnkr.co/edit/vRvnNUULmBpkbLUYk4uw?p=preview
As developer033 mentioned in a comment, you are passing in a single value to the filter pipe, when the filter pipe is expecting an array of values. I would tell the pipe to expect a single value instead of an array
export class FilterPipe implements PipeTransform {
transform(items: any[], term: string): any {
// I am unsure what id is here. did you mean title?
return items.filter(item => item.id.indexOf(term) !== -1);
}
}
I would agree with DeborahK that impure pipes should be avoided for performance reasons. The plunkr includes console logs where you can see how much the impure pipe is called.
Floating will result in wrapping if space is not available.
You can use display:inline
and white-space:nowrap
to achieve this. Fiddle
<div id="container" style="white-space:nowrap">
<div id="image" style="display:inline;">
<img src="tree.png"/>
</div>
<div id="texts" style="display:inline; white-space:nowrap;">
A very long text(about 300 words)
</div>
</div>?
The filter function wasn't working for me at all; maybe the more recent version of jquery doesn't perform as the version used in above code. Regardless; I used:
var black = $('.black');
var white = $('.white');
The selector will find every element classed under black or white. Button functions stay as stated above:
$('#showBlackButton').click(function() {
black.show();
white.hide();
});
$('#showWhiteButton').click(function() {
white.show();
black.hide();
});
In my case, there was a disc space issue. I deleted some unwanted war files from my server and it worked after that.
Another option is to use a single authorize filter as you posted but remove the inner quotations.
[Authorize(Roles="members,admin")]
If you have a form action and an input type="submit"
inside form tags, it's going to submit the old fashioned way and basically refresh the page. When doing AJAX type transactions this isn't the desired effect you are after.
Remove the action. Or remove the form altogether, though in cases it does come in handy to serialize to cut your workload. If the form tags remain, move the button outside the form tags, or alternatively make it a link with an onclick or click handler as opposed to an input button. Jquery UI Buttons works great in this case because you can mimic an input button with an a tag element.
As Michael said, the Chrome extension API doesn't offer a reliable way of doing this. On the other hand: there's a software I've been using myself for quite some time.
Try Sloppy, a Java application that simulates low bandwidth. It's browser independent, it's very easy to use and, best of all, it's free!
In pure JS (provided your browser can handle XHRs, which every major browser [including IE > 6] can):
function igurlretrieve(url) {
var urldsrc = "http://api.instagram.com/oembed?url=" + url;
//fetch data from URL data source
var x = new XMLHttpRequest();
x.open('GET', urldsrc, true);
x.send();
//load resulting JSON data as JS object
var urldata = JSON.parse(x.responseText);
//reconstruct data as "instagram://" URL that can be opened in iOS app
var reconsturl = "instagram://media?id=" + urldata.media_id;
return reconsturl;
}
Provided this is your goal -- simply opening the page in the Instagram iOS app, which is exactly what this is about -- this should do, especially if you don't want to have to endure licensing fees.
Solved.
I was running into the exact same error message when trying to execute the following script (partial) against a remote VM that was configured to be in the WORKGROUP.
Restart-Computer -ComputerName MyComputer -Authentication Default -Credential $cred -force
I noticed I could run the script from another VM in the same WORKGROUP when I disabled the firewall but still couldn't do it from a machine on the domain. Those two things along with Stackflow suggestions is what brought me to the following solution:
Note: Change these settings at your own risk. You should understand the security implications of these changes before applying them.
On the remote machine:
Optional: You may also need to perform the following if you want to run commands like 'Enter-PSSession'.
IMPORTANT! - It's taking my remote VM about 2 minutes or so after it reboots to respond to the 'Enter-PSSession' command even though other networking services are starting up without problems. Give it a couple minutes and then try.
Side Note: Before I changed the 'Remote Address' property to 'Any', both of the rules were set to 'Local subnet'.
Put the CSS files in public/stylesheets and then use:

This question has already been answered perfectly by other people, if you want to do it on your own.
If you prefer to encapsulate or hide away most of the low-level parceling code, you might consider using some of the code I wrote some time ago for simplifying handling of parcelables.
Writing to a parcel is as easy as:
parcelValues(dest, name, maxSpeed, weight, wheels, color, isDriving);
where color is an enum and isDriving is a boolean, for example.
Reading from a parcel is also not much harder:
color = (CarColor)unparcelValue(CarColor.class.getClassLoader());
isDriving = (Boolean)unparcelValue();
Just take a look at the "ParceldroidExample" I added to the project.
Finally, it also keeps the CREATOR initializer short:
public static final Parcelable.Creator<Car> CREATOR =
Parceldroid.getCreatorForClass(Car.class);
for set empty all input such textarea select and input run this code:
$('#message').val('').change();
Using Bootstrap 3's grid system:
<div class="container">
<div class="row">
<div class="col-xs-4">Menu</div>
<div class="col-xs-8">
<div class="row">
<div class="col-md-4 col-md-push-8">Right Content</div>
<div class="col-md-8 col-md-pull-4">Content</div>
</div>
</div>
</div>
</div>
Working example: http://bootply.com/93614
First, we set two columns that will stay in place no matter the screen resolution (col-xs-*
).
Next, we divide the larger, right hand column in to two columns that will collapse on top of each other on tablet sized devices and lower (col-md-*
).
Finally, we shift the display order using the matching class (col-md-[push|pull]-*
). You push the first column over by the amount of the second, and pull the second by the amount of the first.
You'll need to compile it using:
g++ inputfile.cpp -o outputbinary
The file you are referring has a missing #include <cstdlib>
directive, if you also include that in your file, everything shall compile fine.
You can also use generic types, in my case, taking into account everything said before you can do something like:
public class SomeTypeManager<T> {
public SomeTypeManager(T someGeneric) {
//That's how you can achieve all previously said, with generic types.
Annotation[] an = someGeneric.getClass().getAnnotations();
}
}
Remember, that this will not equival at 100% to SomeClass.class.get(...)();
But can do the trick...
Depending on whether you're looking for a member or method, you can use either of these two functions to see if a member/method exists in a particular object:
http://php.net/manual/en/function.method-exists.php
http://php.net/manual/en/function.property-exists.php
More generally if you want all of them:
The mod_authz_host
directives need to be inside a <Location>
or <Directory>
block but I've used the former within <VirtualHost>
like so for Apache 2.2:
<VirtualHost *:8080>
<Location />
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>
...
</VirtualHost>

$('#id-submit').click(function () {
$("input").val(function(i,val) {
return val.toUpperCase();
});
});
Apart from specifying an anchor in a page where you want to jump to, # is also used in jQuery hash or fragment navigation.
// following declaration of delegate ,,,
public delegate long GetEnergyUsageDelegate(DateTime lastRunTime,
DateTime procDateTime);
// following inside of some client method
GetEnergyUsageDelegate nrgDel = GetEnergyUsage;
IAsyncResult aR = nrgDel.BeginInvoke(lastRunTime, procDT, null, null);
while (!aR.IsCompleted) Thread.Sleep(500);
int usageCnt = nrgDel.EndInvoke(aR);
Charles your code(above) is not correct. You do not need to spin wait for completion. EndInvoke will block until the WaitHandle is signaled.
If you want to block until completion you simply need to
nrgDel.EndInvoke(nrgDel.BeginInvoke(lastRuntime,procDT,null,null));
or alternatively
ar.AsyncWaitHandle.WaitOne();
But what is the point of issuing anyc calls if you block? You might as well just use a synchronous call. A better bet would be to not block and pass in a lambda for cleanup:
nrgDel.BeginInvoke(lastRuntime,procDT,(ar)=> {ar.EndInvoke(ar);},null);
One thing to keep in mind is that you must call EndInvoke. A lot of people forget this and end up leaking the WaitHandle as most async implementations release the waithandle in EndInvoke.
If you want to avoid the hassle of escaping the special characters in your search and replacement string when using regular expressions, do the following steps:
Note that even if you want to manually pich matches for the first search and replace, you can safely use "replace all" for the three last steps.
For example, if you want to replace this:
public IFoo SomeField { get { return this.SomeField; } }
with that:
public IFoo Foo { get { return this.MyFoo; } }
public IBar Bar { get { return this.MyBar; } }
You would do the following substitutions:
public IFoo SomeField { get { return this.SomeField; } }
? XOXOXOXO
(regex off).XOXOXOXO
? XOXOXOXO\nHUHUHUHU
(regex on).XOXOXOXO
? public IFoo Foo { get { return this.MyFoo; } }
(regex off).HUHUHUHU
? public IFoo Bar { get { return this.MyBar; } }
(regex off).Or you can use a closure :
render: function() {
...
<a data-tag={i} style={showStyle} onClick={this.removeTag(i)}></a>
...
},
removeTag: function (i) {
return function (e) {
// and you get both `i` and the event `e`
}.bind(this) //important to bind function
}
Select-String
worked best for me. All the other options listed here, such as findstr
, didn't work with large files.
Here's an example:
select-string -pattern "<pattern>" -path "<path>"
note: This requires Powershell
No. This needs to be done in the HTML. You could set the value with Javascript if you need to though.
select
could contain optgroup
which takes one line each:
<select id="list">
<optgroup label="Group 1">
<option value="1">1</option>
</optgroup>
<optgroup label="Group 2">
<option value="2">2</option>
<option value="3">3</option>
</optgroup>
</select>
<script>
const l = document.getElementById("list")
l.setAttribute("size", l.childElementCount + l.length)
</script>
In this example total size
is (1+1)+(1+2)=5
.
what you are searching for is the Export-Csv file.csv
try using Get-Help Export-Csv to see whats possible

In general, the most appropriated way to avoid this problem, (also because of better Mockito integration in JUnit) is to use the Setter/Field Injection as described at https://www.baeldung.com/circular-dependencies-in-spring and at https://docs.spring.io/spring/docs/current/spring-framework-reference/html/beans.html

private Bean1 bean1;
@Autowired
public void setBean1(Bean1 bean1) {
this.bean1 = bean1;
}
}
The scoping rules for Python 2.x have been outlined already in other answers. The only thing I would add is that in Python 3.0, there is also the concept of a non-local scope (indicated by the 'nonlocal' keyword). This allows you to access outer scopes directly, and opens up the ability to do some neat tricks, including lexical closures (without ugly hacks involving mutable objects).
EDIT: Here's the PEP with more information on this.
Try using this attribute, for example for password min length:
[StringLength(100, ErrorMessage = "???????????? ????? ?????? 20 ????????", MinimumLength = User.PasswordMinLength)]
first get the current address
var url = window.location.href
Then just parse that string
var arr = url.split("/");
your url is:
var result = arr[0] + "//" + arr[2]
Hope this helps
The ftp
command isn't designed for scripts, so controlling it is awkward, and getting its exit status is even more awkward.
Curl is made to be scriptable, and also has the merit that you can easily switch to other protocols later by just modifying the URL. If you put your FTP credentials in your .netrc, you can simply do:
# Download file
curl --netrc --remote-name ftp://ftp.example.com/file.bin
# Upload file
curl --netrc --upload-file file.bin ftp://ftp.example.com/
If you must, you can specify username and password directly on the command line using --user username:password
instead of --netrc
.

I recently ran into the same problem, and found a workaround though it'll only be useful if you can change the html code to suit.
I used tables to achieve my padded layout, so to create the equivalent of a div with internal padding I made a table with 3 columns/3 rows and put the content in the centre row/column. The first and last columns/rows are used for the padding.
eg.
<table>
<tr>
<td width="10"> </td>
<td> </td>
<td width="10"> </td>
</tr>
<tr>
<td> </td>
<td>content goes here</td>
<td> </td>
</tr>
<tr>
<td width="10"> </td>
<td> </td>
<td width="10"> </td>
</tr>
</table>
Hope that helps.

The reason that appendChild
is not a function is because you're executing it on the textContent
of your p
element.
You instead just need to select the paragraph itself, and then append your new text node to that:
var paragraph = document.getElementById("p");_x000D_
var text = document.createTextNode("This just got added");_x000D_
_x000D_
paragraph.appendChild(text);
_x000D_
<p id="p">This is some text</p>
_x000D_
However instead, if you like, you can just modify the text itself (rather than adding a new node):
var paragraph = document.getElementById("p");_x000D_
_x000D_
paragraph.textContent += "This just got added";
_x000D_
<p id="p">This is some text</p>
_x000D_

some time ago, I wrote a program just for that: https://github.com/javalite/jar-explorer
Look at strtok(). strtok() is not a re-entrant function.
strtok_r() is the re-entrant version of strtok(). Here's an example program from the manual:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char *argv[])
{
char *str1, *str2, *token, *subtoken;
char *saveptr1, *saveptr2;
int j;
if (argc != 4) {
fprintf(stderr, "Usage: %s string delim subdelim\n",argv[0]);
exit(EXIT_FAILURE);
}
for (j = 1, str1 = argv[1]; ; j++, str1 = NULL) {
token = strtok_r(str1, argv[2], &saveptr1);
if (token == NULL)
break;
printf("%d: %s\n", j, token);
for (str2 = token; ; str2 = NULL) {
subtoken = strtok_r(str2, argv[3], &saveptr2);
if (subtoken == NULL)
break;
printf(" --> %s\n", subtoken);
}
}
exit(EXIT_SUCCESS);
}
Sample run which operates on subtokens which was obtained from the previous token based on a different delimiter:
$ ./a.out hello:word:bye=abc:def:ghi = :
1: hello:word:bye
--> hello
--> word
--> bye
2: abc:def:ghi
--> abc
--> def
--> ghi
Please try this:
<input class="col-xs-12 col-sm-8 col-sm-offset-2 col-md-8 col-md-offset-2" type="text" name="name" value="" placeholder="Your Name" style="background-color:blue;"/>
You basically put all the CSS inside the style part of the input tag and it works.
find supports wildcard matches, just add a *

You have to tell the system what information to log and where to put the info. Logging is configured in the /etc/rsyslog.conf
file, then restart rsyslog to load the new config. The default logging rules are usually in a /etc/rsyslog.d/50-default.conf
file.
To give the code that nstehr's answer refers to (from its source):

message: 'unconverted data remains: .234234'. If %S is in the
format string and the ValueError matches as above, a datetime

I had a really similar issue using HIVE in EMR. None of the extant solutions worked for me -- ie, none of the mapreduce configurations worked for me; and neither did setting yarn.nodemanager.vmem-check-enabled

However, what ended up working was setting tez.am.resource.memory.mb
, for example:
hive -hiveconf tez.am.resource.memory.mb=4096
Another setting to consider tweaking is yarn.app.mapreduce.am.resource.mb

TextMate Integration
You can always pipe the current selection or current document to one of the above, as most editors allow you to do. You can also easily configure the environment so that pandoc
replaces the default Markdown processor used by the Markdown bundle.
First, create a shell script with the following contents (I'll call it ghmarkdown
):
#!/bin/bash
# Note included, optional --email-obfuscation arg
pandoc -f markdown_github --email-obfuscation=references
You can then set the TM_MARKDOWN
variable (in Preferences?Variables) to /path/to/ghmarkdown
, and it will replace the default Markdown processor.
There are loads of ways to do this, but by far the neatest is surely using [NSPredicate predicateWithBlock:]
:
NSArray *filteredArray = [array filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id object, NSDictionary *bindings) {
return [object shouldIKeepYou]; // Return YES for each object you want in filteredArray.
}]];
I think that's about as concise as it gets.
For those working with NSArray
s in Swift, you may prefer this even more concise version:
let filteredArray = array.filter { $0.shouldIKeepYou() }
filter
is just a method on Array
(NSArray
is implicitly bridged to Swift’s Array
). It takes one argument: a closure that takes one object in the array and returns a Bool
. In your closure, just return true
for any objects you want in the filtered array.
Pure bash
total=0; for i in $(cat files.txt | xargs ls -l | cut -c 23-30); do
total=$(( $total + $i )); done; echo $total
Since I needed to analyze fat jars I was interested in the version of each individual class in a jar file. Therefore I took Joe Liversedge approach https://stackoverflow.com/a/27877215/1497139 and combined it with David J. Liszewski' https://stackoverflow.com/a/3313839/1497139 class number version table to create a bash script jarv to show the versions of all class files in a jar file.

Try this:

Dear You have used two Intent launcher in your Manifest. Make only one Activity as launcher: Your manifest activity is :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.th.mybook"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".MainTabPanel"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="MyBookActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.ALTERNATIVE" />
</intent-filter>
</activity>
</application>
</manifest>
now write code will be ( i have made your 'MyActivityBook' your default activity launcher. Copy and paste it on your manifest.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.th.mybook"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".MainTabPanel"
android:label="@string/app_name" >
</activity>
<activity
android:name="MyBookActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and Second error may be if you copy paste old code then please update com.example.packagename.FILE_NAME
hope this will work !
Set width
HeaderStyle-width
for Example HeaderStyle-width="10%"
You can simply access like
Context mContext;
public View onCreateView(LayoutInflater inflater,
@Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mContext = getActivity();
}
and then use
FragmentManager fm = ((FragmentActivity) mContext)
.getSupportFragmentManager();
Now you can use the SQL Server Management Studio to do this.
A solution is to use the include
statement with remote_user
var (describe there : http://docs.ansible.com/playbooks_roles.html) but it has to be done at playbook instead of task level.
Adapting @LainIwakura's answer for modern CMake syntax with imported targets, this would be:
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost 1.45.0 COMPONENTS filesystem regex)
if(Boost_FOUND)
add_executable(progname file1.cxx file2.cxx)
target_link_libraries(progname Boost::filesystem Boost::regex)
endif()
Note that it is not necessary anymore to specify the include directories manually, since it is already taken care of through the imported targets Boost::filesystem
and Boost::regex
.
regex
and filesystem
can be replaced by any boost libraries you need.
For SQL Server 2005+, if there is no insert trigger, then change the insert statement (all one line, split for clarity here) to this
INSERT INTO aspnet_GameProfiles(UserId,GameId)
OUTPUT INSERTED.ID
VALUES(@UserId, @GameId)
For SQL Server 2000, or if there is an insert trigger:
INSERT INTO aspnet_GameProfiles(UserId,GameId)
VALUES(@UserId, @GameId);
SELECT SCOPE_IDENTITY()
And then
Int32 newId = (Int32) myCommand.ExecuteScalar();
"origin/master" refers to the reference poiting to the HEAD commit of branch "origin/master".
A reference is a human-friendly alias name to a Git object, typically a commit object.
"origin/master" reference only gets updated when you git push
to your remote (http://git-scm.com/book/en/v2/Git-Internals-Git-References#Remotes).
From within the root of your project, run:
cat .git/refs/remotes/origin/master
Compare the displayed commit ID with:
cat .git/refs/heads/master
They should be the same, and that's why Git says master
is up-to-date with origin/master
.
When you run
git fetch origin master
That retrieves new Git objects locally under .git/objects folder. And Git updates .git/FETCH_HEAD so that now, it points to the latest commit of the fetched branch.
So to see the differences between your current local branch, and the branch fetched from upstream, you can run
git diff HEAD FETCH_HEAD
In python3, if you a string of b'bytes'
, with json
you have to .decode()
the content before you can load it. simplejson
takes care of this so you can just do simplejson.loads(byte_string)
.
Cool feature. I just want to point out the emphasis on why this is better than string.format if it is not apparent to some people.
I read someone saying order string.format to "{0} {1} {2}" to match the parameters. You are not forced to order "{0} {1} {2}" in string.format, you can also do "{2} {0} {1}". However, if you have a lot of parameters, like 20, you really want to sequence the string to "{0} {1} {2} ... {19}". If it is a shuffled mess, you will have a hard time lining up your parameters.
With $, you can add parameter inline without counting your parameters. This makes the code much easier to read and maintain.
The downside of $ is, you cannot repeat the parameter in the string easily, you have to type it. For example, if you are tired of typing System.Environment.NewLine, you can do string.format("...{0}...{0}...{0}", System.Environment.NewLine), but, in $, you have to repeat it. You cannot do $"{0}" and pass it to string.format because $"{0}" returns "0".
On the side note, I have read a comment in another duplicated tpoic. I couldn't comment, so, here it is. He said that
string msg = n + " sheep, " + m + " chickens";
creates more than one string objects. This is not true actually. If you do this in a single line, it only creates one string and placed in the string cache.
1) string + string + string + string;
2) string.format()
3) stringBuilder.ToString()
4) $""
All of them return a string and only creates one value in the cache.
On the other hand:
string+= string2;
string+= string2;
string+= string2;
string+= string2;
Creates 4 different values in the cache because there are 4 ";".
Thus, it will be easier to write code like the following, but you would create five interpolated string as Carlos Muñoz corrected:
string msg = $"Hello this is {myName}, " +
$"My phone number {myPhone}, " +
$"My email {myEmail}, " +
$"My address {myAddress}, and " +
$"My preference {myPreference}.";
This creates one single string in the cache while you have very easy to read code. I am not sure about the performance, but, I am sure MS will optimize it if not already doing it.
I solved it using the following:
foreach (var image in images)
{
iTextSharp.text.Image pic = iTextSharp.text.Image.GetInstance(image, System.Drawing.Imaging.ImageFormat.Jpeg);
if (pic.Height > pic.Width)
{
//Maximum height is 800 pixels.
float percentage = 0.0f;
percentage = 700 / pic.Height;
pic.ScalePercent(percentage * 100);
}
else
{
//Maximum width is 600 pixels.
float percentage = 0.0f;
percentage = 540 / pic.Width;
pic.ScalePercent(percentage * 100);
}
pic.Border = iTextSharp.text.Rectangle.BOX;
pic.BorderColor = iTextSharp.text.BaseColor.BLACK;
pic.BorderWidth = 3f;
document.Add(pic);
document.NewPage();
}
