You could also use:
var latLon = L.latLng(40.737, -73.923);
var bounds = latLon.toBounds(500); // 500 = metres
map.panTo(latLon).fitBounds(bounds);
This will set the view level to fit the bounds in the map leaflet.
In my case, I have various layer groups so that users can show/hide clusters of like type markers. But, in any case you delete an individual marker by looping over your layer groups to find and delete it. While looping, search for a marker with a custom attribute, in my case a 'key', added when the marker was added to the layer group. Add your 'key' just like adding a title attribute. Later this is gotten an a layer option. When you find that match, you .removeLayer() and it gets rid of that particular marker. Hope that helps you out!
eventsLayerGroup.addLayer(L.marker([tag.latitude, tag.longitude],{title:tag.title, layer:tag.layer, timestamp:tag.timestamp, key:tag.key, bounceOnAdd: true, icon: L.AwesomeMarkers.icon({icon: 'vignette', markerColor: 'blue', prefix: '', iconColor: 'white'}) }).bindPopup(customPopup(tag),customOptions).on('click', markerClick));
function removeMarker(id){
var layerGroupsArray = [eventsLayerGroup,landmarksLayerGroup,travelerLayerGroup,marketplaceLayerGroup,myLayerGroup];
$.each(layerGroupsArray, function (key, value) {
value.eachLayer(function (layer) {
if(typeof value !== "undefined"){
if (layer.options.layer){
console.log(layer.options.key);
console.log(id);
if (id === layer.options.key){
value.removeLayer(layer);
}
}
}
});
});
}
In order to split the ui into two equal parts you can use weightSum of 2 in the parent LinearLayout and assign layout_weight of 1 to each as shown below
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="2">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical">
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical">
</LinearLayout>
</LinearLayout>
Assuming that the question is asking what's the minimum bits required for you to store
My approach to this question would be:
This problem can be solved this way by dividing 999 by 2 recursively. However, it's simpler to use the power of maths to help us. Essentially, we're solving n for the equation below:
2^n = 999
nlog2 = log999
n ~ 10
You'll need 10 bits to store 3 digit number.
Use similar approach to solve the other subquestions!
Hope this helps!

Just to add to the answers, I think the specific reason in this case, in addition to the misplaced no-repeat
, is the space between url
and (
:
background-image: url ('/image/btn.png') no-repeat; /* Won't work */
background-image: url('/image/btn.png'); /* Should work */
So the suggested answer from TheHippo did not work for me, instead I ended up sending the form as a parameter to the function like so:
<form name="loginform" novalidate ng-submit="login.submit(loginForm)" class="css-form">
This makes the form available in the controller method:
$scope.login = {
submit : function(form) {
if(form.$valid)....
}
I second Dipaks' answer, but often just the text-indent is enough as you may/maynot be positioning the ul for better layout control.
ul li{
text-indent: -1em;
}
Yeah, I'm using tf 2.0-beta and want to enable/disable the default logging. The environment variable and methods in tf1.X don't seem to exist anymore.
I stepped around in PDB and found this to work:
# close the TF2 logger
tf2logger = tf.get_logger()
tf2logger.error('Close TF2 logger handlers')
tf2logger.root.removeHandler(tf2logger.root.handlers[0])
I then add my own logger API (in this case file-based)
logtf = logging.getLogger('DST')
logtf.setLevel(logging.DEBUG)
# file handler
logfile='/tmp/tf_s.log'
fh = logging.FileHandler(logfile)
fh.setFormatter( logging.Formatter('fh %(asctime)s %(name)s %(filename)s:%(lineno)d :%(message)s') )
logtf.addHandler(fh)
logtf.info('writing to %s', logfile)
You can use an echo with a pipe to avoid prompts or confirmation.
echo "This is the body" | mail -s "This is the subject" [email protected]
In order to close the port you could identify the process that is listening on this port and kill this process.
You want to execute code where the id is not (1 or 2 or 3), but the OR operator does not distribute over id. The only way to say what you want is to say
the id is not 1, and the id is not 2, and the id is not 3.
which translates to
if (id !== 1 && id !== 2 && id !== 3)
or alternatively for something more pythonesque:
if (!(id in [,1,2,3]))
Use Apache Commons Lang:
String a= "\\*\\";
str = StringUtils.replace(xpath, ".", a);
or with standalone JDK:
String a = "\\*\\"; // or: String a = "/*/";
String replacement = Matcher.quoteReplacement(a);
String searchString = Pattern.quote(".");
String str = xpath.replaceAll(searchString, replacement);
This should work :
<td>{{ number_format($Expense->price, 2) }}</td>
You can watch
props to execute some code upon props changes:
new Vue({_x000D_
el: '#app',_x000D_
data: {_x000D_
text: 'Hello'_x000D_
},_x000D_
components: {_x000D_
'child' : {_x000D_
template: `<p>{{ myprop }}</p>`,_x000D_
props: ['myprop'],_x000D_
watch: { _x000D_
myprop: function(newVal, oldVal) { // watch it_x000D_
console.log('Prop changed: ', newVal, ' | was: ', oldVal)_x000D_
}_x000D_
}_x000D_
}_x000D_
}_x000D_
});

Calling async
code from synchronous code can be quite tricky.
I explain the full reasons for this deadlock on my blog. In short, there's a "context" that is saved by default at the beginning of each await
and used to resume the method.
So if this is called in an UI context, when the await
completes, the async
method tries to re-enter that context to continue executing. Unfortunately, code using Wait
(or Result
) will block a thread in that context, so the async
method cannot complete.
The guidelines to avoid this are:
ConfigureAwait(continueOnCapturedContext: false)
as much as possible. This enables your async
methods to continue executing without having to re-enter the context.async
all the way. Use await
instead of Result
or Wait
.If your method is naturally asynchronous, then you (probably) shouldn't expose a synchronous wrapper.
If you are looking for a hard limit across all uploads on the site, you can limit these in php.ini by setting the following:
`upload_max_filesize = 2M` `post_max_size = 2M`
that will set the maximum upload limit to 2 MB
You have to do something like:
case 1:
case 2:
case 3:
//do stuff
break;
I found this query to be easy to use & quick.
select schema_name(tab.schema_id) + '.' + tab.name as [table],
cast(sum(spc.used_pages * 8)/1024.00 as numeric(36, 2)) as used_mb,
cast(sum(spc.total_pages * 8)/1024.00 as numeric(36, 2)) as allocated_mb
from sys.tables (nolock) tab
inner join sys.indexes (nolock) ind
on tab.object_id = ind.object_id
inner join sys.partitions (nolock) part
on ind.object_id = part.object_id and ind.index_id = part.index_id
inner join sys.allocation_units (nolock) spc
on part.partition_id = spc.container_id
group by schema_name(tab.schema_id) + '.' + tab.name
order by sum(spc.used_pages) desc
here is what works with the version of the program that I'm using: may work for you too.
I will just place the instruction and command that does it. class is the name of the table. you change it in the table its self with this method. not just the return on the search process.
view the table class
select * from class
change the length of the columns FacID (seen as "faci") and classnumber (seen as "classnu") to fit the whole labels.
alter table class modify facid varchar (5);
alter table class modify classnumber varchar(11);
view table again to see the difference
select * from class;
(run the command again to see the difference)
This changes the the actual table for good, but for better.
P.S. I made these instructions up as a note for the commands. This is not a test, but can help on one :)
Bart Kiers, your regex has a couple issues. The best way to do that is this:
(.*[a-z].*) // For lower cases
(.*[A-Z].*) // For upper cases
(.*\d.*) // For digits
In this way you are searching no matter if at the beginning, at the end or at the middle. In your have I have a lot of troubles with complex passwords.
It's explained in great detail in the docs, but I'll try to summarize:
matching
means git push
will push all your local branches to the ones with the same name on the remote. This makes it easy to accidentally push a branch you didn't intend to.
simple
means git push
will push only the current branch to the one that git pull
would pull from, and also checks that their names match. This is a more intuitive behavior, which is why the default is getting changed to this.
This setting only affects the behavior of your local client, and can be overridden by explicitly specifying which branches you want to push on the command line. Other clients can have different settings, it only affects what happens when you don't specify which branches you want to push.
Adding this to your code android:focusableInTouchMode="true"
will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.
ie: In your app_list_view.xml file
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:focusableInTouchMode="true">
<EditText
android:id="@+id/filter_edittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Search"
android:inputType="text"
android:maxLines="1"/>
<ListView
android:id="@id/android:list"
android:layout_height="fill_parent"
android:layout_weight="1.0"
android:layout_width="fill_parent"
android:focusable="true"
android:descendantFocusability="beforeDescendants"/>
</LinearLayout>
------------------ EDIT: To Make keyboard appear on startup -----------------------
This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="20dip"
android:paddingRight="20dip">
<EditText
android:id="@+id/userName"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Username"
android:imeOptions="actionDone"
android:inputType="text"
android:maxLines="1"
/>
<EditText
android:id="@+id/password"
android:password="true"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Password" />
<ScrollView
android:id="@+id/ScrollView01"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</ScrollView>
</LinearLayout>
If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.
Hope this is what you are looking for.
Cheers!
You should look into Video For Everyone:
Video for Everybody is very simply a chunk of HTML code that embeds a video into a website using the HTML5 element which offers native playback in Firefox 3.5 and Safari 3 & 4 and an increasing number of other browsers.
The video is played by the browser itself. It loads quickly and doesn’t threaten to crash your browser.
In other browsers that do not support , it falls back to QuickTime.
If QuickTime is not installed, Adobe Flash is used. You can host locally or embed any Flash file, such as a YouTube video.
The only downside, is that you have to have 2/3 versions of the same video stored, but you can serve to every existing device/browser that supports video (i.e.: the iPhone).

I recently needed to solve this problem as well and ended up writing a Ruby script for this: https://github.com/vaneyckt/git-find-branching-point
Beware of the use of push method, if you don't use indexes, it won't work!
var main2dArray: Things[][] = []
main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)
gives only a 1 line array!
use
main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray
to get your 2d array working!!!
Other beware! foreach doesn't seem to work with 2d arrays!
It can be usefull. Bindings dose not always work.
<select id="product" class="form-control" name="product" required
ng-model="issue.productId"
ng-change="getProductVersions()"
ng-options="p.id as p.shortName for p in products">
</select>
For example. You fill options list source model from rest-service. Selected value was known befor filling list and was set. After executing rest-request with $http list option be done. But selected option is not set. By unknown reasons AngularJS in shadow $digest executing not bind selected as it shuold be. I gotta use JQuery to set selected. It`s important! Angular in shadow add prefix to value of attr "value" for generated by ng-repeat optinos. For int it is "number:".
$scope.issue.productId = productId;
function activate() {
$http.get('/product/list')
.then(function (response) {
$scope.products = response.data;
if (productId) {
console.log("" + $("#product option").length);//for clarity
$timeout(function () {
console.log("" + $("#product option").length);//for clarity
$('#product').val('number:'+productId);
//$scope.issue.productId = productId;//not work at all
}, 200);
}
});
}
Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.
http://www.rgagnon.com/javadetails/java-0542.html
Edit: Here's a working ultra-minimalistic file sender and receiver. Make sure you understand what the code is doing on both sides.

Threading code is often buggy and always hard to test. You don't need to write threading code to update the user interface from a background task. Just use the BackgroundWorker class to run the task and its ReportProgress method to update the user interface. Usually, you just report a percentage complete, but there's another overload that includes a state object. Here's an example that just reports a string object:
private void button1_Click(object sender, EventArgs e)
{
backgroundWorker1.WorkerReportsProgress = true;
backgroundWorker1.RunWorkerAsync();
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
Thread.Sleep(5000);
backgroundWorker1.ReportProgress(0, "A");
Thread.Sleep(5000);
backgroundWorker1.ReportProgress(0, "B");
Thread.Sleep(5000);
backgroundWorker1.ReportProgress(0, "C");
}
private void backgroundWorker1_ProgressChanged(
object sender,
ProgressChangedEventArgs e)
{
label1.Text = e.UserState.ToString();
}
That's fine if you always want to update the same field. If you've got more complicated updates to make, you could define a class to represent the UI state and pass it to the ReportProgress method.
One final thing, be sure to set the WorkerReportsProgress
flag, or the ReportProgress
method will be completely ignored.
ansible-playbook test.yml --extra-vars "arg1=${var1} arg2=${var2}"

and -e
are the same, you can use one of them.
The notion of complex numbers was introduced in mathematics, from the need of calculating negative quadratic roots. Complex number concept was taken by a variety of engineering fields.
Today that complex numbers are widely used in advanced engineering domains such as physics, electronics, mechanics, astronomy, etc...
Real and imaginary part, of a negative square root example:
#include <stdio.h>
#include <complex.h>
int main()
{
int negNum;
printf("Calculate negative square roots:\n"
"Enter negative number:");
scanf("%d", &negNum);
double complex negSqrt = csqrt(negNum);
double pReal = creal(negSqrt);
double pImag = cimag(negSqrt);
printf("\nReal part %f, imaginary part %f"
", for negative square root.(%d)",
pReal, pImag, negNum);
return 0;
}
I had a similar problem, when I wanted to automatically remove temp files I had created. The solution I came up with was not to use command substitution, but rather to pass the name of the variable, that should take the final result, into the function. E.g.
#! /bin/bash
remove_later=""
new_tmp_file() {
file=$(mktemp)
remove_later="$remove_later $file"
eval $1=$file
}
remove_tmp_files() {
rm $remove_later
}
trap remove_tmp_files EXIT
new_tmp_file tmpfile1
new_tmp_file tmpfile2
So, in your case that would be:
#!/bin/bash
e=2
function test1() {
e=4
eval $1="hello"
}
test1 ret
echo "$ret"
echo "$e"
Works and has no restrictions on the "return value".
which nginx
will give you the path of the nginx being used
EDIT (2017-Jan-18)
Thanks to Will Palmer's comment on this answer, I have added the following...
If you've installed nginx via a package manager such as HomeBrew...
which nginx
may not give you the EXACT path to the nginx being used. You can however find it using
realpath $(which nginx)
and as mentioned by @Daniel Li
you can get configuration of nginx via his method
alternatively you can use this:
nginx -V
You should put your component between an enclosing tag, Which means:

If you are using VB as code behind, you have to use bracket "()" instead of square bracket "[]".
Example for VB:
<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>
Ensure you have the latest TensorFlow 2.x GPU installed in your GPU supporting machine, Execute the following code in python,
from __future__ import absolute_import, division, print_function, unicode_literals
import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))
Will get an output looks like,

var somefancyvariable = "fancy";
Object.keys({somefancyvariable})[0];
This isn't able to be made into a function as it returns the name of the function's variable.
// THIS DOESN'T WORK
function getVarName(v) {
return Object.keys({v})[0];
}
// Returns "v"
Edit: Thanks to @Madeo for pointing out how to make this into a function.
function debugVar(varObj) {
var varName = Object.keys(varObj)[0];
console.log("Var \"" + varName + "\" has a value of \"" + varObj[varName] + "\"");
}
You will need call the function with a single element array containing the variable. debugVar({somefancyvariable});
Edit: Object.keys
can be referenced as just keys

XAMPP comes preloaded with the FileZilla FTP server. Here is how to setup the service, and create an account.
Enable the FileZilla FTP Service through the XAMPP Control Panel to make it startup automatically (check the checkbox next to filezilla to install the service). Then manually start the service.
Create an ftp account through the FileZilla Server Interface (its the essentially the filezilla control panel). There is a link to it Start Menu in XAMPP folder. Then go to Users->Add User->Stuff->Done.
Try connecting to the server (localhost, port 21).
Don't forget to convert your object into Json first using Gson()
val fromUserJson = Gson().toJson(notificationRequest.fromUser)
Then you can easily convert it back into an object using this awesome library
val fromUser = Gson().fromJson(fromUserJson, User::class.java)
There are several ways rsync compares files -- the authoritative source is the rsync algorithm description: https://www.andrew.cmu.edu/course/15-749/READINGS/required/cas/tridgell96.pdf. The wikipedia article on rsync is also very good.
For local files, rsync compares metadata and if it looks like it doesn't need to copy the file because size and timestamp match between source and destination it doesn't look further. If they don't match, it cp's the file. However, what if the metadata do match but files aren't actually the same? Then rsync probably didn't do what you intended.
Files that are the same size may still have changed. One simple example is a text file where you correct a typo -- like changing "teh" to "the". The file size is the same, but the corrected file will have a newer timestamp. --size-only
says "don't look at the time; if size matches assume files match", which would be the wrong choice in this case.
On the other hand, suppose you accidentally did a big cp -r A B
yesterday, but you forgot to preserve the time stamps, and now you want to do the operation in reverse rsync B A
. All those files you cp'ed have yesterday's time stamp, even though they weren't really modified yesterday, and rsync will by default end up copying all those files, and updating the timestamp to yesterday too. --size-only
may be your friend in this case (modulo the example above).
--ignore-times
says to compare the files regardless of whether the files have the same modify time. Consider the typo example above, but then not only did you correct the typo but you used touch
to make the corrected file have the same modify time as the original file -- let's just say you're sneaky that way. Well --ignore-times
will do a diff of the files even though the size and time match.

From Ubuntu command line:
//WeatherArray.java
public class WeatherArray {
public static void main(String[] args) {
System.out.println("....Hello World");
}}
ls
WeatherArray.java
javac WeatherArray.java
ls
WeatherArray.java WeatherArray.class
java WeatherArray
....Hello World
Of course if you name your java file with different name than WeatherArray, you need to take out public and it would be:
// Sunny.java
class WeatherArray {
public static void main(String[] args) {
System.out.println("....Hello World"); }}
// javac Sunny.java; java WeatherArray
Ok so if an image in a table is clicked you want the data of the first row of the table this image is in.
//image click stuff here {
$(this). // our image
closest('table'). // Go upwards through our parents untill we hit the table
children('tr:first'); // Select the first row we find
var $row = $(this).closest('table').children('tr:first');
parent()
will only get the direct parent, closest
should do what we want here.
From jQuery docs: Get the first ancestor element that matches the selector, beginning at the current element and progressing up through the DOM tree.
use DIRECTORY option.
Documentation here: http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_import.htm#SUTIL907
DIRECTORY
Default: DATA_PUMP_DIR
Purpose
Specifies the default location in which the import job can find the dump file set and where it should create log and SQL files.
Syntax and Description
DIRECTORY=directory_object
The directory_object is the name of a database directory object (not the file path of an actual directory). Upon installation, privileged users have access to a default directory object named DATA_PUMP_DIR. Users with access to the default DATA_PUMP_DIR directory object do not need to use the DIRECTORY parameter at all.
A directory object specified on the DUMPFILE, LOGFILE, or SQLFILE parameter overrides any directory object that you specify for the DIRECTORY parameter. You must have Read access to the directory used for the dump file set and Write access to the directory used to create the log and SQL files.
Example
The following is an example of using the DIRECTORY parameter. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. See "FULL".
> impdp hr DIRECTORY=dpump_dir1 DUMPFILE=expfull.dmp
LOGFILE=dpump_dir2:expfull.log
This command results in the import job looking for the expfull.dmp dump file in the directory pointed to by the dpump_dir1 directory object. The dpump_dir2 directory object specified on the LOGFILE parameter overrides the DIRECTORY parameter so that the log file is written to dpump_dir2.
List<string> l = new List<string> { "@bob.com", "@tom.com" };
List<string> l2 = new List<string> { "[email protected]", "[email protected]" };
List<string> myboblist= (l2.Where (i=>i.Contains("bob")).ToList<string>());
foreach (var bob in myboblist)
Console.WriteLine(bob.ToString());
Debugging Tips
markus@ubuntu:~$ patch -Np1 --ignore-whitespace -d software-1.0 < fix-bug.patch
see tutorial by markusIndependent of the shell being used (sh, ksh, bash, ...) the following approach works pretty well for n-dimensional arrays (the sample covers a 2-dimensional array).
In the sample the line-separator (1st dimension) is the space character. For introducing a field separator (2nd dimension) the standard unix tool tr
is used. Additional separators for additional dimensions can be used in the same way.
Of course the performance of this approach is not very well, but if performance is not a criteria this approach is quite generic and can solve many problems:
array2d="1.1:1.2:1.3 2.1:2.2 3.1:3.2:3.3:3.4"
function process2ndDimension {
for dimension2 in $*
do
echo -n $dimension2 " "
done
echo
}
function process1stDimension {
for dimension1 in $array2d
do
process2ndDimension `echo $dimension1 | tr : " "`
done
}
process1stDimension
The output of that sample looks like this:
1.1 1.2 1.3
2.1 2.2
3.1 3.2 3.3 3.4
Also there is a jQuery plugin that adds some methods on an array:
Implementing Prototype’s Array Methods in jQuery
This plugin implements Prototype's library array methods such as:
var arr = [1,2,3,4,5,6];
$.protify(arr, true);
arr.all(); // true
var arr = $.protify([1, 2, 3, 4, 5, 6]);
arr.any(); // true
And more.
clone() was designed with several mistakes (see this question), so it's best to avoid it.
From Effective Java 2nd Edition, Item 11: Override clone judiciously
Given all of the problems associated with Cloneable, it’s safe to say that other interfaces should not extend it, and that classes designed for inheritance (Item 17) should not implement it. Because of its many shortcomings, some expert programmers simply choose never to override the clone method and never to invoke it except, perhaps, to copy arrays. If you design a class for inheritance, be aware that if you choose not to provide a well-behaved protected clone method, it will be impossible for subclasses to implement Cloneable.
This book also describes the many advantages copy constructors have over Cloneable/clone.
All standard collections have copy constructors. Use them.
List<Double> original = // some list
List<Double> copy = new ArrayList<Double>(original);
Please try this one works for me:
<ImageView android:id="@+id/image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:maxWidth="60dp"
android:layout_gravity="center"
android:maxHeight="60dp"
android:scaleType="fitCenter"
android:src="@drawable/icon"

You need to define the server instance in the Servers view.
In the box at the right bottom, press the Servers tab and add the server there. You by the way don't necessarily need to add it through global IDE preferences. It will be automagically added when you define it in Servers view. The preference you've modified just defines default locations, not the whole server instance itself. If you for instance upgrade/move the server, you can change the physical location there.
Once defining the server in the Servers view, you need to add the newly created server instance to the project through its Server and Targeted runtime preference.
Not to bring up an old post but I landed on this question in my search for the same solution. I ended up coming up with something of my own. Figured I'd contribute.

I get into ElementNotVisibleException exception using selenium for functional tests on a django site with bootstrap glyphicons as links in templates as:
<a href="{% url 'item-add' %}"><span class="glyphicon glyphicon-plus text-danger"></span></a>
During my functional tests, the bootstrap style is not loaded, then trying to click on such links will raise ElementNotVisibleException. I manage to make them clickable just adding a space in the tag, like that:
<a href="{% url 'item-add' %}"><span class="glyphicon glyphicon-plus text-danger"> </span></a>
How about this for IE?:
onmousedown: Hide all elements which could overlay the event. Because display:none visibility:hidden not realy works, push the overlaying div out of the screen for a fixed number of pixels. After a delay push back the overlaying div with the same number of pixels.
onmouseup: Meanwhile this is the event you like to fire.
//script
var allclickthrough=[];
function hidedivover(){
if(allclickthrough.length==0){
allclickthrough=getElementsByClassName(document.body,"clickthrough");// if so .parentNode
}
for(var i=0;i<allclickthrough.length;i++){
allclickthrough[i].style.left=parseInt(allclickthrough[i].style.left)+2000+"px";
}
setTimeout(function(){showdivover()},1000);
}
function showdivover(){
for(var i=0;i<allclickthrough.length;i++){
allclickthrough[i].style.left=parseInt(allclickthrough[i].style.left)-2000+"px";
}
}
//html

<div onmousedown="hidedivover()" style="position:absolute" class="clickthrough">You'll don't get through!</div>

Theres an excellent tutorial on this subject at HelloAndroid regarding this very subject. Infact it was the first hit i got on google. You should try googling before asking here, as it is good practice.
It should be a Python expression that, when eval'd, creates an object with the exact same properties as this one. For example, if you have a Fraction
class that contains two integers, a numerator and denominator, your __repr__()
method would look like this:
# in the definition of Fraction class
def __repr__(self):
return "Fraction(%d, %d)" % (self.numerator, self.denominator)
Assuming that the constructor takes those two values.
Try to use:
location.reload(true);
When this method receives a true
value as argument, it will cause the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

You could try that XCode plugin https://github.com/benoitsan/BBUncrustifyPlugin-Xcode
Just clone github repository, open plugin project in XCode and run it. It will be installed automatically. Restart Xode before using formatter plugin.
Don't forget to install uncrustify util before. Homebrew, for exmaple
brew install uncrustify
P.S. You can turn on "after save formatting" feature at Edit > Format Code > BBUncrustifyPlugin Preferences > Format On Save
Hope this will be useful for u ;-)
You can have a look at AngularStrap, the navbar directive seems to be what you are looking for:
https://github.com/mgcrea/angular-strap/blob/master/src/navbar/navbar.js
.directive('bsNavbar', function($location) {
'use strict';
return {
restrict: 'A',
link: function postLink(scope, element, attrs, controller) {
// Watch for the $location
scope.$watch(function() {
return $location.path();
}, function(newValue, oldValue) {
$('li[data-match-route]', element).each(function(k, li) {
var $li = angular.element(li),
// data('match-rout') does not work with dynamic attributes
pattern = $li.attr('data-match-route'),
regexp = new RegExp('^' + pattern + '$', ['i']);
if(regexp.test(newValue)) {
$li.addClass('active');
} else {
$li.removeClass('active');
}
});
});
}
};
});
To use this directive:
Download AngularStrap from http://mgcrea.github.io/angular-strap/
Include the script on your page after bootstrap.js:
<script src="lib/angular-strap.js"></script>
Add the directives to your module:
angular.module('myApp', ['$strap.directives'])
Add the directive to your navbar:
<div class="navbar" bs-navbar>
Add regexes on each nav item:
<li data-match-route="/about"><a href="#/about">About</a></li>
ls -lart | tail -n +2 #argument means starting with line 2
You asked for a combination of quick, nice, no use of a boolean, no use of goto, and C#. You've ruled out all possible ways of doing what you want.
The most quick and least ugly way is to use a goto.
The only way to call a non-static method from a static method is to have an instance of the class containing the non-static method.
class A
{
void method()
{
}
}
class Demo
{
static void method2()
{
A a=new A();
a.method();
}
/*
void method3()
{
A a=new A();
a.method();
}
*/
public static void main(String args[])
{
A a=new A();
/*an instance of the class is created to access non-static method from a static method */
a.method();
method2();
/*method3();it will show error non-static method can not be accessed from a static method*/
}
}
Have a go at Selenium (http://seleniumhq.org) or WatiN (http://watin.sourceforge.net) to save yourself some work.
Performance wise substring(0, 1)
is better as found by following:
String example = "something";
String firstLetter = "";
long l=System.nanoTime();
firstLetter = String.valueOf(example.charAt(0));
System.out.println("String.valueOf: "+ (System.nanoTime()-l));
l=System.nanoTime();
firstLetter = Character.toString(example.charAt(0));
System.out.println("Character.toString: "+ (System.nanoTime()-l));
l=System.nanoTime();
firstLetter = example.substring(0, 1);
System.out.println("substring: "+ (System.nanoTime()-l));
Output:
String.valueOf: 38553
Character.toString: 30451
substring: 8660
After about a half hour of searching and trying to debug this I was able to figure it out. My situation involved me using the same pem file for two different ec2 instance and it working for one and not the other.
My first instance it worked on was the standard aws linux ami amzn-ami-hvm-2014.03.2.x86_64-ebs. I simply used
ssh -i mypemfile.pem ec2-user@myec2ipaddress
and it worked.
I then launched a fedora instance Fedora-x86_64-19-20140407-sda and tried the same command but kept getting:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
After changing my username from ec2-user to fedora it worked!
ssh -i mypemfile.pem fedora@myec2address
sudo apt-get install zlib1g:i386 fixed the Gradle issue on Android 2.1.1 on Xubuntu 16.04.
The __dict__
property of the object is a dictionary of all its other defined properties. Note that Python classes can override getattr
and make things that look like properties but are not in__dict__
. There's also the builtin functions vars()
and dir()
which are different in subtle ways. And __slots__
can replace __dict__
in some unusual classes.
Objects are complicated in Python. __dict__
is the right place to start for reflection-style programming. dir()
is the place to start if you're hacking around in an interactive shell.

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.
So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.
Solution:
By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution
The heredoc solutions are certainly the most common way to do this. Other common solutions are:
echo 'line 1, '"${kernel}"' line 2, line 3, '"${distro}"' line 4' > /etc/myconfig.conf
and
exec 3>&1 # Save current stdout exec > /etc/myconfig.conf echo line 1, ${kernel} echo line 2, echo line 3, ${distro} ... exec 1>&3 # Restore stdout
Render Line Endings is a VS Code extension that is still actively maintained (as of Apr 2020):
https://marketplace.visualstudio.com/items?itemName=medo64.render-crlf
https://github.com/medo64/render-crlf/
It can be configured like this:
{
"editor.renderWhitespace": "all",
"code-eol.newlineCharacter": "¬",
"code-eol.returnCharacter" : "¤",
"code-eol.crlfCharacter" : "¤¬",
}
and looks like this:
Inspired by the idea from @MarSoft but I changed the lines like the following:
USERNAME='desireduser'
COMMAND=$0
COMMANDARGS="$(printf " %q" "${@}")"
if [ $(whoami) != "$USERNAME" ]; then
exec sudo -E su $USERNAME -c "/usr/bin/bash -l $COMMAND $COMMANDARGS"
exit
fi
I have used sudo
to allow a password less execution of the script. If you want to enter a password for the user, remove the sudo
. If you do not need the environment variables, remove -E
from sudo.
The /usr/bin/bash -l
ensures, that the profile.d
scripts are executed for an initialized environment.
Alright Let's say you have a brand new project, if so you would go to settings.py
file and search for TEMPLATES
once you found it you just paste this line os.path.join(BASE_DIR, 'template')
in 'DIRS'
At the end, you should get somethings like this :
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
os.path.join(BASE_DIR, 'template')
],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
If you want to know where your BASE_DIR directory is located type these 3 simple commands:
python3 manage.py shell
Once you're in the shell :
>>> from django.conf import settings
>>> settings.BASE_DIR
PS: If you named your template folder with another name, you would change it here too.
Or run a pip install --upgrade pip enum34
Ok, I think I got it.
The client is the docker
command installed into OS X.
The host is the Boot2Docker VM.
The daemon is a background service running inside Boot2Docker.
This variable tells the client how to connect to the daemon.
When starting Boot2Docker, the terminal window that pops up already has DOCKER_HOST
set, so that's why docker
commands work. However, to run Docker commands in other terminal windows, you need to set this variable in those windows.
Failing to set it gives a message like this:
$ docker run hello-world
2014/08/11 11:41:42 Post http:///var/run/docker.sock/v1.13/containers/create:
dial unix /var/run/docker.sock: no such file or directory
One way to fix that would be to simply do this:
$ export DOCKER_HOST=tcp://192.168.59.103:2375
But, as pointed out by others, it's better to do this:
$ $(boot2docker shellinit)
$ docker run hello-world
Hello from Docker. [...]
To spell out this possibly non-intuitive Bash command, running boot2docker shellinit
returns a set of Bash commands that set environment variables:
export DOCKER_HOST=tcp://192.168.59.103:2376
export DOCKER_CERT_PATH=/Users/ddavison/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1
Hence running $(boot2docker shellinit)
generates those commands, and then runs them.
This statement will definitely help you:
env = env.OrderByDescending(c => c.ReportDate).ToList();
Following @rsplak answer: actually, using split/join way is faster than using regexp. See the performance test case
So
var result = text.split(' ').join('')
operates faster than
var result = text.replace(/\s+/g, '')
On small texts this is not relevant, but for cases when time is important, e.g. in text analisers, especially when interacting with users, that is important.
On the other hand, \s+
handles wider variety of space characters. Among with \n
and \t
, it also matches \u00a0
character, and that is what
is turned in, when getting text using textDomNode.nodeValue
.
So I think that conclusion in here can be made as follows: if you only need to replace spaces ' '
, use split/join. If there can be different symbols of symbol class - use replace(/\s+/g, '')
You should set the timezone to the one of the timezones you want.
// set default timezone
date_default_timezone_set('America/Chicago'); // CDT
$info = getdate();
$date = $info['mday'];
$month = $info['mon'];
$year = $info['year'];
$hour = $info['hours'];
$min = $info['minutes'];
$sec = $info['seconds'];
$current_date = "$date/$month/$year == $hour:$min:$sec";
Or a much shorter version:
// set default timezone
date_default_timezone_set('America/Chicago'); // CDT
$current_date = date('d/m/Y == H:i:s');
I am using CentOS and had same problem.

// ParseErrors is an ArrayList containing any errors from the Load statement
if (htmlDoc.ParseErrors != null && htmlDoc.ParseErrors.Count() > 0)
{
// Handle any parse errors as required
}
else

HtmlAgilityPack.HtmlNode bodyNode = htmlDoc.DocumentNode.SelectSingleNode("//body");
if (bodyNode != null)
{
// Do something with bodyNode
}
}
}
(NB: This code is an example only and not necessarily the best/only approach. Do not use it blindly in your own application.)
The HtmlDocument.Load()
method also accepts a stream which is very useful in integrating with other stream oriented classes in the .NET framework. While HtmlEntity.DeEntitize()
is another useful method for processing html entities correctly. (thanks Matthew)
HtmlDocument
and HtmlNode
are the classes you'll use most. Similar to an XML parser, it provides the selectSingleNode and selectNodes methods that accept XPath expressions.
Pay attention to the HtmlDocument.Option??????
boolean properties. These control how the Load
and LoadXML
methods will process your HTML/XHTML.
There is also a compiled help file called HtmlAgilityPack.chm that has a complete reference for each of the objects. This is normally in the base folder of the solution.
For those using yarn.
I tried using npm shrinkwrap until I discovered the yarn cli ignored my npm-shrinkwrap.json file.
Yarn has https://yarnpkg.com/lang/en/docs/selective-version-resolutions/ for this. Neat.

Another veneration of find_elements_by_xpath(".//*")
is:
from selenium.webdriver.common.by import By
find_elements(By.XPATH, ".//*")
Setting android:noHistory="true"
on the activity in your manifest will remove an activity from the stack whenever it is navigated away from. see here
Another way that allows you to change the text of "Delete" and add more buttons when sliding a cell is to use editActionsForRowAtIndexPath
.
func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
return true
}
func tableView(tableView: (UITableView!), commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: (NSIndexPath!)) {
}
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
var deleteAction = UITableViewRowAction(style: .Default, title: "Delete") {action in
//handle delete
}
var editAction = UITableViewRowAction(style: .Normal, title: "Edit") {action in
//handle edit
}
return [deleteAction, editAction]
}
canEditRowAtIndexPath
and commitEditingStyle
are still required, but you can leave commitEditingStyle
empty since deletion is handled in editActionsForRowAtIndexPath
.
Well, you're getting a java.lang.NoClassDefFoundError
. In your pom.xml
, hibernate-core
version is 3.3.2.GA
and declared after hibernate-entitymanager
, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final
from hibernate-entitymanager
.
You're using spring-boot
as parent, so no need to declare version of some dependencies, since they are managed by spring-boot
.
Also, hibernate-commons-annotations
is inherited from hibernate-entitymanager
and hibernate-annotations
is an old version of hibernate-commons-annotations
, you can remove both.
Finally, your pom.xml
can look like this:

Let me know if you have a problem.
You can write your own jQuery plugins(function which can be called on selected elements) like below:
(function( $ ){ $.fn.myFunc = function(param1, param2){ //this - jquery object holds your selected elements } })( jQuery );
Call it later like:
$('div').myFunc(1, null);
1 - Your malloc() is wrong.
2 - You are overstepping the bounds of the allocated memory
3 - You should initialize your allocated memory
Here is the program with all the changes needed. I compiled and ran... no errors or warnings.
#include <stdio.h>
#include <stdlib.h> //malloc
#include <math.h> //sine
#include <string.h>
#define TIME 255
#define HARM 32
int main (void) {
double sineRads;
double sine;
int tcount = 0;
int hcount = 0;
/* allocate some heap memory for the large array of waveform data */
double *ptr = malloc(sizeof(double) * TIME);
//memset( ptr, 0x00, sizeof(double) * TIME); may not always set double to 0
for( tcount = 0; tcount < TIME; tcount++ )
{
ptr[tcount] = 0;
}
tcount = 0;
if (NULL == ptr) {
printf("ERROR: couldn't allocate waveform memory!\n");
} else {
/*evaluate and add harmonic amplitudes for each time step */
for(tcount = 0; tcount < TIME; tcount++){
for(hcount = 0; hcount <= HARM; hcount++){
sineRads = ((double)tcount / (double)TIME) * (2*M_PI); //angular frequency
sineRads *= (hcount + 1); //scale frequency by harmonic number
sine = sin(sineRads);
ptr[tcount] += sine; //add to other results for this time step
}
}
free(ptr);
ptr = NULL;
}
return 0;
}
As of today (Angular 9), Angular uses a Shadow DOM to display the components as custom HTML elements. One elegant way to style those custom elements might be using custom CSS variables. Here is a generic example:
class ChildElement extends HTMLElement {_x000D_
constructor() {_x000D_
super();_x000D_
_x000D_
var shadow = this.attachShadow({mode: 'open'});_x000D_
var wrapper = document.createElement('div');_x000D_
wrapper.setAttribute('class', 'wrapper');_x000D_
_x000D_
// Create some CSS to apply to the shadow dom_x000D_
var style = document.createElement('style');_x000D_
_x000D_
style.textContent = `_x000D_
_x000D_
/* Here we define the default value for the variable --background-clr */_x000D_
:host {_x000D_
--background-clr: green;_x000D_
}_x000D_
_x000D_
.wrapper {_x000D_
width: 100px;_x000D_
height: 100px;_x000D_
background-color: var(--background-clr);_x000D_
border: 1px solid red;_x000D_
}_x000D_
`;_x000D_
_x000D_
shadow.appendChild(style);_x000D_
shadow.appendChild(wrapper);_x000D_
}_x000D_
}_x000D_
_x000D_
// Define the new element_x000D_
customElements.define('child-element', ChildElement);
_x000D_
/* CSS CODE */_x000D_
_x000D_
/* This element is referred as :host from the point of view of the custom element. Commenting out this CSS will result in the background to be green, as defined in the custom element */_x000D_
_x000D_
child-element {_x000D_
--background-clr: yellow; _x000D_
}
_x000D_
<div>_x000D_
<child-element></child-element>_x000D_
</div>
_x000D_
As we can see from the above code, we create a custom element, just like Angular would do for us with every component, and then we override the variable responsible for the background color within the shadow root of the custom element, from the global scope.
In an Angular app, this might be something like:
parent.component.scss
child-element {
--background-clr: yellow;
}
child-element.component.scss
:host {
--background-clr: green;
}
.wrapper {
width: 100px;
height: 100px;
background-color: var(--background-clr);
border: 1px solid red;
}
on this web http://quirksmode.org/css/css2/columns.html i found that easy way
<table>
<col style="background-color: #6374AB; color: #ffffff" />
<col span="2" style="background-color: #07B133; color: #ffffff;" />

If you want to manually count it, the size of a struct is just the size of each of its data members after accounting for alignment. There's no magic overhead bytes for a struct.
function is_json($input) {
$input = trim($input);
if (substr($input,0,1)!='{' OR substr($input,-1,1)!='}')
return false;
return is_array(@json_decode($input, true));
}
Since Julian date 0 is a Monday just add the number of weeks to Sunday which is the day before -1 Eg. select dateadd(wk,datediff(wk,0,getdate()),-1)
As its name is "numbers" it is clear it is a list of number... So an array of number... no need of the attribute type... Although I like the principle of specifying the type of field in a type attribute...

The JVM resizes the heap adaptively, meaning it will attempt to find the best heap size for your application. -Xms and -Xmx simply specifies the range in which the JVM can operate and resize the heap. If -Xms and -Xmx are the same value, then the JVM's heap size will stay constant at that value.
It's typically best to just set -Xmx and let the JVM find the best heap size, unless there's a specific reason why you need to give the JVM a big heap at JVM launch.
As far as when the JVM actually requests the memory from the OS, I believe it depends on the platform and implementation of the JVM. I imagine that it wouldn't request the memory until your app actually needs it. -Xmx and -Xms just reserves the memory.
Can I use (http://caniuse.com/#feat=datauri) shows support across the major browsers with few issues on IE.
few day ago I have the SAME problem with 1 table.
Firstly try:
echo json_encode($rows);
echo json_last_error(); // returns 5 ?
If last line returns 5, problem is with your data. I know, your tables are in UTF-8, but not entered data. For example the input was in txt file, but created on Win machine with stupid encoding (in my case Win-1250 = CP1250) and this data has been entered into the DB.
Solution? Look for new data (excel, web page), edit source txt file via PSPad (or whatever else), change encoding to UTF-8, delete all rows and now put data from original. Save. Enter into DB.
You can also only change encoding to utf-8 and then change all rows manually (give cols with special chars - desc, ...). Good for slaves...
Yes, It is called the for-each loop. Objects in the collectionName will be assigned one after one from the beginning of that collection, to the created object reference, 'objectName'. So in each iteration of the loop, the 'objectName' will be assigned an object from the 'collectionName' collection. The loop will terminate once when all the items(objects) of the 'collectionName' Collection have finished been assigning or simply the objects to get are over.
for (ObjectType objectName : collectionName.getObjects()){ //loop body> //You can use the 'objectName' here as needed and different objects will be //reepresented by it in each iteration. }
if playing with psql inside docker exec it like this:
docker exec -e "PGOPTIONS=--search_path=<your_schema>" -it docker_pg psql -U user db_name
This is how you do it:
$http({ url: 'your/webservice', method: 'POST', responseType: 'arraybuffer', data: json, //this is your json data string headers: { 'Content-type': 'application/json', 'Accept': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' } }).success(function(data){ var blob = new Blob([data], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' }); saveAs(blob, 'File_Name_With_Some_Unique_Id_Time' + '.xlsx'); }).error(function(){ //Some error log });
Tip! Don't mix " and ', stick to always use ', in a professional environment you will have to pass js validation for example jshint, same goes for using === and not ==, and so on, but that is another topic :)
I would put the save excel in another service, so you have clean structure and the post is in a proper service of its own. I can make a JS fiddle for you, if you don't get my example working. Then I would also need some json data from you that you use for a full example.
Happy coding.. Eduardo
On the left we have the app organized by type. Not too bad for smaller apps, but even here you can start to see it gets more difficult to find what you are looking for. When I want to find a specific view and its controller, they are in different folders. It can be good to start here if you are not sure how else to organize the code as it is quite easy to shift to the technique on the right: structure by feature.
On the right the project is organized by feature. All of the layout views and controllers go in the layout folder, the admin content goes in the admin folder, and the services that are used by all of the areas go in the services folder. The idea here is that when you are looking for the code that makes a feature work, it is located in one place. Services are a bit different as they “service” many features. I like this once my app starts to take shape as it becomes a lot easier to manage for me.

For parseInt to work, your string should have only numerical data. Something like this:
str1 = "123.00";
str2 = "50.00";
total = parseInt(str1)+parseInt(str2);
alert(total);
Can you split the string before you start processing them for a total?
You may have enough correct answers for your question but in case your IDE gives you the warning
Promise returned from navigate is ignored
you may either ignore that warning or use this.router.navigate(['/your-path']).then()
.
Run this:
SELECT CASE transaction_isolation_level
WHEN 0 THEN 'Unspecified'
WHEN 1 THEN 'ReadUncommitted'
WHEN 2 THEN 'ReadCommitted'
WHEN 3 THEN 'Repeatable'
WHEN 4 THEN 'Serializable'
WHEN 5 THEN 'Snapshot' END AS TRANSACTION_ISOLATION_LEVEL
FROM sys.dm_exec_sessions
where session_id = @@SPID
one way you could handle this is with a generator. Instead of calling the function, yield it; then whatever is consuming the generator can send the result of calling it back into the generator, or a sentinel if the generator failed: The trampoline that accomplishes the above might look like so:
def consume_exceptions(gen):
action = next(gen)
while True:
try:
result = action()
except Exception:
# if the action fails, send a sentinel
result = None
try:
action = gen.send(result)
except StopIteration:
# if the generator is all used up, result is the return value.
return result
a generator that would be compatible with this would look like this:
def do_smth1():
1 / 0
def do_smth2():
print "YAY"
def do_many_things():
a = yield do_smth1
b = yield do_smth2
yield "Done"
>>> consume_exceptions(do_many_things())
YAY
Note that do_many_things()
does not call do_smth*
, it just yields them, and consume_exceptions
calls them on its behalf
@CarlosLanderas is correct depending on where you've placed the DIV control. The DIV by the way is not technically an ASP control, which is why you cannot find it directly like other controls. But the best way around this is to turn it into an ASP control.
Use asp:Panel instead. It is rendered into a <div>
tag anyway...
<asp:Panel id="divSubmitted" runat="server" style="text-align:center" visible="false">
<asp:Label ID="labSubmitted" runat="server" Text="Roll Call Submitted"></asp:Label>
</asp:Panel>
And in code behind, simply find the Panel control as per normal...
Panel DivCtl1 = (Panel)gvRollCall.FooterRow.FindControl("divSubmitted");
if (DivCtl1 != null)
DivCtl1.Visible = true;
Please note that I've used FooterRow, as my "psuedo div" is inside the footer row of a Gridview control.
Good coding!

I had the same problem running on Windows 8 running on 64bit. Apache is really slow but when you press F5 many times it goes ok. In the end i after doing many things managed to solve it. Right now it works fast.
Try the following tasks to increase the performance:
Change listening port from 80 to 8080 to avoid conflicts with programs like Skype. Open your httpd.conf file and find the line that starts with Listen
(it's around line 62). Change it like the following:
Listen 127.0.0.1:8080
Change your power plan from Balanced to High Performance. You can do this in Control Panel\All Control Panel Items\Power Options
The credits of this particular task go to Jef where he pointed this out in his blog post. From the Windows 8 desktop, press the Windows Key
and the R key
at the same time
Type regedit in the Run dialog box and click OK
Use Registry Editor to expand the registry tree and browse to:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP6\Parameters
Right click on Parameters
, expand New
, and select DWORD (32-bit)
Value
Enter DisabledComponents
into the Name
field
Double click on the new DisabledComponents
value, enter ffffffff
into the Value data
dialog box, and click the OK
button
Confirm the new registry value contains the required data.
If you use virtual hosts don't add each virtual host on a new line. Instead list them like the following.
127.0.0.1 site-a site-b site-c
I also added 127.0.0.1 127.0.0.1
since I heard this somehow improves the lookup as well. (Can't confirm this but it can't hurt putting it there)
Your hosts file is located at C:\Windows\System32\Drivers\etc
In my case I had two apache processes running. Be sure you only have one running. You can check this by pressing CTRL+ALT+DEL
and press Task Manager
What I find to be working a bit as well was turning off the Base Filtering Engine. Since stopping or disabling the BFE service will significantly reduce the security of the system you should only do this when needed.
Go to Control Panel => Administrative Tools => Services => Base Filtering Engine
Stop the Base Filtering Engine by clicking on Stop
To to your task manager and change Apache's process priority from Normal to High by right clicking -> Set priority -> High
This is a bit of an ugly method but it does certainly work. It keeps Apache busy and will process your own requests faster. Insert your local web-address in the iframe location and save it in a html file, run it and just leave it there until you're done.

If .DS_Store was never added to your git repository, simply add it to your .gitignore file.
If you don't have one, create a file called
.gitignore
In the root directory of your app and simply write
**/.DS_Store
In it. This will never allow the .DS_Store file to sneak in your git.
But, if it's already there, write in your terminal:
find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch
then commit and push the changes to remove the .DS_Store from your remote repo:
git commit -m "Remove .DS_Store from everywhere"
git push origin master
And now add .DS_Store to your .gitignore file, and then again commit and push with the 2 last pieces of code (git commit..., git push...)
These examples are from php.net. Thanks to you, I also just learned about the new php hashing functions.
Read the php documentation to find out about the possibilities and best practices: http://www.php.net/manual/en/function.password-hash.php
Save a password hash:
$options = [
'cost' => 11,
];
// Get the password from post
$passwordFromPost = $_POST['password'];
$hash = password_hash($passwordFromPost, PASSWORD_BCRYPT, $options);
// Now insert it (with login or whatever) into your database, use mysqli or pdo!
Get the password hash:
// Get the password from the database and compare it to a variable (for example post)
$passwordFromPost = $_POST['password'];
$hashedPasswordFromDB = ...;
if (password_verify($passwordFromPost, $hashedPasswordFromDB)) {
echo 'Password is valid!';
} else {
echo 'Invalid password.';
}
This response doesn't pertain to your stated question, but to an implicit question I see in the code you posted, ie, "how to check if something is an integer?"
The first answer you'll generally get to that question is "Don't!" And it's true that in Python, typechecking is usually not the right thing to do.
For those rare exceptions, though, instead of looking for a decimal point in the string representation of the number, the thing to do is use the isinstance function:
>>> isinstance(5,int)
True
>>> isinstance(5.0,int)
False
Of course this applies to the variable rather than a value. If I wanted to determine whether the value was an integer, I'd do this:
>>> x=5.0
>>> round(x) == x
True
But as everyone else has covered in detail, there are floating-point issues to be considered in most non-toy examples of this kind of thing.
If you have access to JavaScript, you can create an element and read its computed style.
function defaultValueOfCssPropertyForElement(cssPropertyName, elementTagName, opt_pseudoElement) {
var pseudoElement = opt_pseudoElement || null;
var element = document.createElement(elementTagName);
document.body.appendChild(element);
var computedStyle = getComputedStyle(element, pseudoElement)[cssPropertyName];
element.remove();
return computedStyle;
}
// Usage:
defaultValueOfCssPropertyForElement('display', 'div'); // Output: 'block'
defaultValueOfCssPropertyForElement('content', 'div', ':after'); // Output: 'none'
If .attr()
isn't working for you (especially when checking and unchecking boxes in succession), use .prop()
instead of .attr()
.
You should use Jérôme Petazzoni's tool called 'nsenter' to enter a container without using SSH. See: https://github.com/jpetazzo/nsenter
Install with simply running: docker run -v /usr/local/bin:/target jpetazzo/nsenter
Then use the command docker-enter <container-id>
to enter the container.
Using System.arraycopy()
, something like the following should work:
// create a destination array that is the size of the two arrays
byte[] destination = new byte[ciphertext.length + mac.length];
// copy ciphertext into start of destination (from pos 0, copy ciphertext.length bytes)
System.arraycopy(ciphertext, 0, destination, 0, ciphertext.length);
// copy mac into end of destination (from pos ciphertext.length, copy mac.length bytes)
System.arraycopy(mac, 0, destination, ciphertext.length, mac.length);
Use this below simple code: https://jsfiddle.net/Divyesh_Patel/v7a4h3kr/7/

1.Open notepad
2.Create new file
3.type bellow line
dir /b > fileslist.txt
4.Save "list.bat
"
Thats it. now you can copy & paste this "list.bat
" file any of your folder location and double click it, it will create a "fileslist.txt
" along with that directory folder and file name list.
Note: If you want create file name list along with sub folder, then you can create batch file with bellow code.
dir /b /s > fileslist.txt
If you don't want to read the whole file into memory at once, you can use a few tricks:
With next(iterator)
you can advance to the next line:
with open("filename.txt") as f:
next(f)
next(f)
next(f)
for line in f:
print(f)
Of course, this is slighly ugly, so itertools has a better way of doing this:
from itertools import islice
with open("filename.txt") as f:
# start at line 17 and never stop (None), until the end
for line in islice(f, 17, None):
print(f)
.getBoundingClientRect() returns the size of an element and its position relative to the viewport.We can easily get following
Example :
var element = d3.select('.elementClassName').node();
element.getBoundingClientRect().width;
You'll have to set it to zero. Zero means the script can run forever. Add the following at the start of your script:
ini_set('max_execution_time', 0);
Refer to the PHP documentation of max_execution_time
Note that:
set_time_limit(0);
will have the same effect.
If you are on a Windows machine, go to the directory:
C:\Program Files\Android\Android Studio\gradle\
Click the gradle-4.4 folder from Android Studio\File\Settings, and then click the Apply button.
Those steps should be able to be shortened down to:
hg pull
hg update -r MY_BRANCH -C
The -C
flag tells the update command to discard all local changes before updating.
However, this might still leave untracked files in your repository. It sounds like you want to get rid of those as well, so I would use the purge
extension for that:
hg pull
hg update -r MY_BRANCH -C
hg purge
In any case, there is no single one command you can ask Mercurial to perform that will do everything you want here, except if you change the process to that "full clone" method that you say you can't do.
You can follow what paxdiablo(on Dec '12) suggested for an automated, more versatile approach:
for (int row = 0; row < 3; row ++)
for (int col = 0; col < 3; col++)
table[row][col] = (char) ('1' + row * 3 + col);
In terms of efficiency, it depends on the scale of your implementation.
If it is to simply initialize a 2D array to values 0-9, it would be much easier to just define, declare and initialize within the same statement like this:
private char[][] table = {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}};
Or if you're planning to expand the algorithm, the previous code would prove more, efficient.
make sure you use the POST to insert the data. Actually you were using GET.
There is a easy solution for that problem, the solution is removed the certificate the yours Keychain, the previous thing will cause that it asks again to the user and password.
Steps:
Search the certificate gitHub.com.
Remove gitHub.com certificate.
Execute any operation with git in your terminal. this again ask your username and password.
For Windows Users find the key chain by following:
Control Panel >> User Account >> Credential Manager >> Windows Credential >> Generic Credential
Maybe I misunderstood your question, but wouldn't it be simpler if you copy/move the files from A to the git repo B and add the needed ones with git add?
UPDATE: From the git doc:
Cloning into an existing directory is only allowed if the directory is empty.
try
$("#btnId").click(function(e){
e.preventDefault();
//show loading gif
$.ajax({
...
success:function(data){
//remove gif
},
error:function(){//remove gif}
});
});
EDIT: after reading the comments
in case you decide against ajax
$("#btnId").click(function(e){
e.preventDefault();
//show loading gif
$(this).closest('form').submit();
});
In Swift:
tableView.alwaysBounceVertical = false
Here's how you can do it all in one line:
df[['a', 'b']].fillna(value=0, inplace=True)
Breakdown: df[['a', 'b']]
selects the columns you want to fill NaN values for, value=0
tells it to fill NaNs with zero, and inplace=True
will make the changes permanent, without having to make a copy of the object.
Use try catch:
try
{
SqlCommand check_User_Name = new SqlCommand("SELECT * FROM Table WHERE ([user] = '" + txtBox_UserName.Text + "') ", conn);
int UserExist = (int)check_User_Name.ExecuteScalar();
// Update query
}
catch
{
// Insert query
}
private void Form1_Load(object sender, EventArgs e)
{
//Write a file
string text = "The text inside the file.";
System.IO.File.WriteAllText("file_name.txt", text);
//Read a file
string read = System.IO.File.ReadAllText("file_name.txt");
MessageBox.Show(read); //Display text in the file
}
You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.
You will then do e.g.:
wget www.google.com
I fixed the issue (temporarily) by going to Edit Scheme, then in the Build section, removing my unit test target from being invoked in "Run".
Always use

"WORKSPACE" environment variable works for the latest version of Jenkins Pipeline. You can use this in your Jenkins file: "${env.WORKSPACE}"
Sample use below:
def files = findFiles glob: '**/reports/*.json'
for (def i=0; i<files.length; i++) {
jsonFilePath = "${files[i].path}"
jsonPath = "${env.WORKSPACE}" + "/" + jsonFilePath
echo jsonPath

The simplest way is this:
while (cursor.moveToNext()) {
...
}
The cursor starts before the first result row, so on the first iteration this moves to the first result if it exists. If the cursor is empty, or the last row has already been processed, then the loop exits neatly.
Of course, don't forget to close the cursor once you're done with it, preferably in a finally
clause.
Cursor cursor = db.rawQuery(...);
try {
while (cursor.moveToNext()) {
...
}
} finally {
cursor.close();
}
If you target API 19+, you can use try-with-resources.
try (Cursor cursor = db.rawQuery(...)) {
while (cursor.moveToNext()) {
...
}
}
A core is usually the basic computation unit of the CPU - it can run a single program context (or multiple ones if it supports hardware threads such as hyperthreading on Intel CPUs), maintaining the correct program state, registers, and correct execution order, and performing the operations through ALUs. For optimization purposes, a core can also hold on-core caches with copies of frequently used memory chunks.
A CPU may have one or more cores to perform tasks at a given time. These tasks are usually software processes and threads that the OS schedules. Note that the OS may have many threads to run, but the CPU can only run X such tasks at a given time, where X = number cores * number of hardware threads per core. The rest would have to wait for the OS to schedule them whether by preempting currently running tasks or any other means.
In addition to the one or many cores, the CPU will include some interconnect that connects the cores to the outside world, and usually also a large "last-level" shared cache. There are multiple other key elements required to make a CPU work, but their exact locations may differ according to design. You'll need a memory controller to talk to the memory, I/O controllers (display, PCIe, USB, etc..). In the past these elements were outside the CPU, in the complementary "chipset", but most modern design have integrated them into the CPU.
In addition the CPU may have an integrated GPU, and pretty much everything else the designer wanted to keep close for performance, power and manufacturing considerations. CPU design is mostly trending in to what's called system on chip (SoC).
This is a "classic" design, used by most modern general-purpose devices (client PC, servers, and also tablet and smartphones). You can find more elaborate designs, usually in the academy, where the computations is not done in basic "core-like" units.

Solved! I found some lack of library for PostgreSQL on the system. Only two steps solved it:
brew install postgresql
Then run
gem install pg
i was struggling with this even after setting --max-old-space-size.
Then i realised need to put options --max-old-space-size before the karma script.
also best to specify both syntaxes --max-old-space-size and --max_old_space_size my script for karma :
node --max-old-space-size=8192 --optimize-for-size --max-executable-size=8192 --max_old_space_size=8192 --optimize_for_size --max_executable_size=8192 node_modules/karma/bin/karma start --single-run --max_new_space_size=8192 --prod --aot

<DataGrid

ItemsSource="{Binding Data_Table}"
SelectedItem="{Binding Select_Request, Mode=TwoWay}" SelectionChanged="DataGrid_SelectionChanged"/>//The binding
#region View Model
private DataRowView select_request;

}
This script:
import subprocess
import os
with open(os.devnull, "wb") as limbo:
for n in xrange(1, 10):
ip="192.168.0.{0}".format(n)
result=subprocess.Popen(["ping", "-c", "1", "-n", "-W", "2", ip],
stdout=limbo, stderr=limbo).wait()
if result:
print ip, "inactive"
else:
print ip, "active"
will produce something like this output:
192.168.0.1 active
192.168.0.2 active
192.168.0.3 inactive
192.168.0.4 inactive
192.168.0.5 inactive
192.168.0.6 inactive
192.168.0.7 active
192.168.0.8 inactive
192.168.0.9 inactive
You can capture the output if you replace limbo
with subprocess.PIPE
and use communicate()
on the Popen
object:
p=Popen( ... )
output=p.communicate()
result=p.wait()
This way you get the return value of the command and can capture the text. Following the manual this is the preferred way to operate a subprocess if you need flexibility:
The underlying process creation and management in this module is handled by the Popen class. It offers a lot of flexibility so that developers are able to handle the less common cases not covered by the convenience functions.
You should move your switch into the template by using the 'ng-switch' directive:
module.directive('testForm', function() {
return {
restrict: 'E',
controllerAs: 'form',
controller: function ($scope) {
console.log("Form controller initialization");
var self = this;
this.fields = {};
this.addField = function(field) {
console.log("New field: ", field);
self.fields[field.name] = field;
};
}
}
});
module.directive('formField', function () {
return {
require: "^testForm",
template:
'<div ng-switch="field.fieldType">' +
' <span>{{title}}:</span>' +
' <input' +
' ng-switch-when="text"' +
' name="{{field.name}}"' +
' type="text"' +
' ng-model="field.value"' +
' />' +
' <select' +
' ng-switch-when="select"' +
' name="{{field.name}}"' +
' ng-model="field.value"' +
' ng-options="option for option in options">' +
' <option value=""></option>' +
' </select>' +
'</div>',
restrict: 'E',
replace: true,
scope: {
fieldType: "@",
title: "@",
name: "@",
value: "@",
options: "=",
},
link: function($scope, $element, $attrs, form) {
$scope.field = $scope;
form.addField($scope);
}
};
});
It can be use like this:
<test-form>
<div>
User '{{!form.fields.email.value}}' will be a {{!form.fields.role.value}}
</div>
<form-field title="Email" name="email" field-type="text" value="[email protected]"></form-field>
<form-field title="Role" name="role" field-type="select" options="['Cook', 'Eater']"></form-field>
<form-field title="Sex" name="sex" field-type="select" options="['Awesome', 'So-so', 'awful']"></form-field>
</test-form>

And then just have an association between that and your class.
You can sort indexes using values as keys:
indexes = range(len(list1))
indexes.sort(key=list1.__getitem__)
To get sorted lists given sorted indexes:
sorted_list1 = map(list1.__getitem__, indexes)
sorted_list2 = map(list2.__getitem__, indexes)
In your case you shouldn't have list1
, list2
but rather a single list of pairs:
data = [(3, 'three'), (2, 'two'), (4, 'four'), (1, 'one'), (1, 'one2')]
It is easy to create; it is easy to sort in Python:
data.sort() # sort using a pair as a key
Sort by the first value only:
data.sort(key=lambda pair: pair[0])
Two-way binding just means that:
Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.
In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "change" event. To achieve #2, you need to also add a change listener to the input element, and call model.set
in the handler.
Here's a Fiddle with two-way binding set up in Backbone.
You could look at the Wikipedia article on Standard Deviation, in particular the section about Rapid calculation methods.
There's also an article I found that uses Python, you should be able to use the code in it without much change: Subliminal Messages - Running Standard Deviations.

Let me use names a
(in place of XXX
and ZZZ
) and b
(in place of YYY
), since that makes the description a bit easier to read.
Say you want to merge repository a
into b
(I'm assuming they're located alongside one another):
cd a
git filter-repo --to-subdirectory-filter a
cd ..
cd b
git remote add a ../a
git fetch a
git merge --allow-unrelated-histories a/master
git remote remove a
For this you need git-filter-repo
installed (filter-branch
is discouraged).

If session.cookie_lifetime
is 0, the session cookie lives until the browser is quit.
EDIT: Others have mentioned the session.gc_maxlifetime
setting. When session garbage collection occurs, the garbage collector will delete any session data that has not been accessed in longer than session.gc_maxlifetime
seconds. To set the time-to-live for the session cookie, call session_set_cookie_params()
or define the session.cookie_lifetime
PHP setting. If this setting is greater than session.gc_maxlifetime
, you should increase session.gc_maxlifetime
to a value greater than or equal to the cookie lifetime to ensure that your sessions won't expire.
I don't have an exact solution, but I'll post my experiences with this in case they help anyone else.
From my testing, the gray screen is only triggered on slower machines [1]. To date, I have not been able to recreate it on newer hardware [2]. All of my tests have been in IE8 with Adobe Reader 10.1.2. For my tests I turned off SSL and removed all headers that could have disabled caching.
To recreate the gray screen, I followed the following steps:
1) Navigate to a page that links to a PDF
2) Open the PDF in a new window or tab (either via the context menu or target="_blank")
3) In my tests, this PDF will open without error (however I have received user reports indicating failure on the first PDF load)
4) Close the newly opened window or tab
5) Open the PDF (again) in a new window or tab
6) This PDF will not open, but instead only show the "gray screen" mentioned by the first user (all subsequent PDFs that are loaded will also not display -- until all browser windows are closed)
I performed the above test with several different PDF files (both static and dynamic) generated from different sources and the gray screen issue always occurs when following the above steps (on the "slow" computer).
To mitigate the problem in my application, I "tore down" the page that links to the PDF (removed parts piece by piece until the gray screen no longer occurred). In my particular application (built on closure-library) removing all references to goog.userAgent.adobeReader [3] appears to have fixed the issue. This exact solution won't work with jquery or .net MVC but maybe the process can help you isolate the source of the issue. I have not yet taken the time to isolate which particular portion of goog.userAgent.adobeReader triggers the bug in Adobe Reader, but it is likely that jquery might have similar plugin detection code to that used in closure-library.

But if u lazy just add inline
before the function
So it will look something like this
inline void functionX()
{ }
more about inline functions:
The inline functions are a C++ enhancement feature to increase the execution time of a program. Functions can be instructed to compiler to make them inline so that compiler can replace those function definition wherever those are being called. Compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime. NOTE- This is just a suggestion to compiler to make the function inline, if function is big (in term of executable instruction etc) then, compiler can ignore the “inline” request and treat the function as normal function.

Expanding on @gecco 's answer, the following is an example that'll show you the difference:
def foo(**kwargs):
for entry in kwargs.items():
print("Key: {}, value: {}".format(entry[0], entry[1]))
# call using normal keys:
foo(a=1, b=2, c=3)
# call using an unpacked dictionary:
foo(**{"a": 1, "b":2, "c":3})
# call using a dictionary fails because the function will think you are
# giving it a positional argument
foo({"a": 1, "b": 2, "c": 3})
# this yields the same error as any other positional argument
foo(3)
foo("string")
Here you can see how unpacking a dictionary works, and why sending an actual dictionary fails

All the stuff about .on() and .one() is great, and jquery is great.
But sometimes, you want it to be a little more obvious that the user isn't allowed to click, and in those cases you could do something like this:
function funName(){
$("#orderButton").prop("disabled", true);
// do a bunch of stuff
// and now that you're all done
setTimeout(function(){
$("#orderButton").prop("disabled",false);
$("#orderButton").blur();
}, 3000);
}
and your button would look like:
<button onclick='funName()'>Click here</button>

String p = request.getParameter("password");
try {
st = con.createStatement();

please replace * with your IP address for example: jupyter notebook --ip=192.168.x.x --no-browser
you can now access your jupyter server from any device connected to the router using this ip:port (the port is usually 8888, so for my case for instance I used "192.168.x.x:8888" to access my server from other devices)

The browser will execute the scripts in the order it finds them. If you call an external script, it will block the page until the script has been loaded and executed.
To test this fact:
// file: test.php
sleep(10);
die("alert('Done!');");
// HTML file:
<script type="text/javascript" src="test.php"></script>
Dynamically added scripts are executed as soon as they are appended to the document.
To test this fact:
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
</head>
<body>
<script type="text/javascript">
var s = document.createElement('script');
s.type = "text/javascript";
s.src = "link.js"; // file contains alert("hello!");
document.body.appendChild(s);
alert("appended");
</script>
<script type="text/javascript">
alert("final");
</script>
</body>
</html>
Order of alerts is "appended" -> "hello!" -> "final"
If in a script you attempt to access an element that hasn't been reached yet (example: <script>do something with #blah</script><div id="blah"></div>
) then you will get an error.
Overall, yes you can include external scripts and then access their functions and variables, but only if you exit the current <script>
tag and start a new one.
You can't do it with "anonymous" type parameters (ie, wildcards that use ?
), but you can do it with "named" type parameters. Simply declare the type parameter at method or class level.

I do this to get the first and last value. This works with more values too.
$a = array(
'foo' => 400,
'bar' => 'xyz',
);
$first = current($a); //400
$last = end($a); //xyz
Your initial page is a complete HTML page containing a form, the contents of which are posted to insert.php when the submit button is clicked, but insert.php needs to process the form's contents and do something with them, like add them to a database, or output them to a new page. Your current insert.php just outputs the contents of the title field, so your browser tries to interpret that as an HTML page, and fails, obviously, because it isn't valid HTML (i.e. it isn't contained in an 'HTML' tag, etc.).
Your insert.php needs to output the necessary HTML, and insert the form data in there somewhere.
For example:
<?php
$title = $_POST["title"];
$price = $_POST["price"];
echo '<html xmlns="http://www.w3.org/1999/xhtml">';
echo '<head>';
echo '<meta http-equiv="content-type" content="text/html; charset=utf-8" />';
echo '<title>';
echo $title;
echo '</title>';
echo '</head>';
echo '<body>';
echo 'Hello, world.';
echo '</body>';
?>
dict.items()
return list of tuples, and dict.iteritems()
return iterator object of tuple in dictionary as (key,value)
. The tuples are the same, but container is different.
dict.items()
basically copies all dictionary into list. Try using following code to compare the execution times of the dict.items()
and dict.iteritems()
. You will see the difference.
import timeit
d = {i:i*2 for i in xrange(10000000)}
start = timeit.default_timer() #more memory intensive
for key,value in d.items():
tmp = key + value #do something like print
t1 = timeit.default_timer() - start
start = timeit.default_timer()
for key,value in d.iteritems(): #less memory intensive
tmp = key + value
t2 = timeit.default_timer() - start
Output in my machine:
Time with d.items(): 9.04773592949
Time with d.iteritems(): 2.17707300186
This clearly shows that dictionary.iteritems()
is much more efficient.
Perhaps a temporary table will do what you want.
CREATE TEMPORARY TABLE SalesSummary (
product_name VARCHAR(50) NOT NULL
, total_sales DECIMAL(12,2) NOT NULL DEFAULT 0.00
, avg_unit_price DECIMAL(7,2) NOT NULL DEFAULT 0.00
, total_units_sold INT UNSIGNED NOT NULL DEFAULT 0
) ENGINE=MEMORY;
INSERT INTO SalesSummary
(product_name, total_sales, avg_unit_price, total_units_sold)
SELECT
p.name
, SUM(oi.sales_amount)
, AVG(oi.unit_price)
, SUM(oi.quantity_sold)
FROM OrderItems oi
INNER JOIN Products p
ON oi.product_id = p.product_id
GROUP BY p.name;
/* Just output the table */
SELECT * FROM SalesSummary;
/* OK, get the highest selling product from the table */
SELECT product_name AS "Top Seller"
FROM SalesSummary
ORDER BY total_sales DESC
LIMIT 1;
/* Explicitly destroy the table */
DROP TABLE SalesSummary;

Suppose I have numbers 1 to 10 in cells A2:A11
with my autofilter in A1
. I now filter to only show numbers greater then 5 (i.e. 6, 7, 8, 9, 10).
This code will only print visible cells:
Sub SpecialLoop()
Dim cl As Range, rng As Range
Set rng = Range("A2:A11")
For Each cl In rng
If cl.EntireRow.Hidden = False Then //Use Hidden property to check if filtered or not
Debug.Print cl
End If
Next
End Sub
Perhaps there is a better way with SpecialCells
but the above worked for me in Excel 2003.
EDIT
Just found a better way with SpecialCells
:
Sub SpecialLoop()
Dim cl As Range, rng As Range
Set rng = Range("A2:A11")
For Each cl In rng.SpecialCells(xlCellTypeVisible)
Debug.Print cl
Next cl
End Sub
Google already published a guide on optimization of PHP and the conclusion was:
No getter and setter Optimizing PHP
And no, you must not use magic methods. For PHP, Magic Method are evil. Why?
PHP is not Java, C++, or C#. PHP is different and plays with different roles.
I think the following suggestion would be the fastest. I am sacrificing the lazyness of the source Enumerable for the ability to use Array.Copy and knowing ahead of the time the length of each of my sublists.
public static IEnumerable<T[]> Chunk<T>(this IEnumerable<T> items, int size)
{
T[] array = items as T[] ?? items.ToArray();
for (int i = 0; i < array.Length; i+=size)
{
T[] chunk = new T[Math.Min(size, array.Length - i)];
Array.Copy(array, i, chunk, 0, chunk.Length);
yield return chunk;
}
}
Incremental development means that different parts of a software project are continuously integrated into the whole, instead of a monolithic approach where all the different parts are assembled in one or a few milestones of the project.
Iterative means that once a first version of a component is complete it is tested, reviewed and the results are almost immediately transformed into a new version (iteration) of this component.
So as a first result: iterative development doesn't need to be incremental and vice versa, but these methods are a good fit.
Agile development aims to reduce massive planing overhead in software projects to allow fast reactions to change e.g. in customer wishes. Incremental and iterative development are almost always part of an agile development strategy. There are several approaches to Agile development (e.g. scrum).
I tried all possible ways to achieve this and then I discovered Minified version of xZing by JourneyApps. I have ported that for eclipse and shared on GitHub.
If you are using eclipse use this project:-
https://github.com/hiteshsahu/XZing-Barcode-Scanner-Minified-Eclipse
If you are using Studio use this project :-
https://github.com/journeyapps/zxing-android-embedded
Advantages
Inbuilt Barcode scanner in your App do not required to install third party apps using playstore.
You dont need to get confused between Core,Android client etc jars simply drop this packages and relevent layouts in your project and you are good to go. Only Jar required is com.google.zxing:core:3.2.0 which you can download from
http://mvnrepository.com/artifact/com.google.zxing/core/3.2.0
No need to add tons of packages see images below for comparison
Before :-
After :-
Most important part is they are highly customizable ie. you can add flash light, use it in fragment and support orientation change.
You can use this Capture activity in Cordova App for barcode scanneing.
your capture activity in app manifest would look like this
<activity
android:name="com.journeyapps.barcodescanner.CaptureActivity"
android:clearTaskOnLaunch="true"
android:configChanges="orientation|keyboardHidden"
android:exported="false"
android:screenOrientation="fullSensor"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden" >
<intent-filter>
<action android:name="com.google.zxing.client.android.SCAN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
and plugin will look like this
public class BarcodeScanner extends CordovaPlugin {
public static final int REQUEST_CODE = 0x0ba7c0de;
private static final String SCAN = "scan";
private static final String CANCELLED = "cancelled";
private static final String FORMAT = "format";

Happy Integration !!
You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:
Dim MyVar as string = "some text ""hello"" "
This will give the MyVar
variable a value of some text "hello"
.
Tried some of answers given above but those fires event twice. Here is working solution if you may need the same.
$('mydiv').one('DOMSubtreeModified', function(){
console.log('changed');
});
if pip is not working than you can download .whl file from here https://pypi.python.org/pypi/psycopg2
extract it..
than python setup.py install
Since Eclipse Neon which contains Eclipse Maven Integration (m2e) 1.7, the preferred way is one of the following ways:
.project
) as well as for non-Eclipse projects that only contain the file pom.xml
.Run vim
from the terminal. For the basics, you're advised to run the command vimtutor
.
# On your terminal command line:
$ vim
If you have a specific file to edit, pass it as an argument.
$ vim yourfile.cpp
Likewise, launch the tutorial
$ vimtutor
Another "Up Tick" for AR..., but if you don't have to use interop I would avoid it altogether. This product is actually quite interesting: http://www.clearoffice.com/ and it provides a very intuitive, fully managed, api for manipulation excel files and seems to be free. (at least for the time being) SpreadSheetGear is also excellent but pricey.
my two cents.
In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.
But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:
{ Id: 1,
name:'john',
phones:[{title:'home',number:111111,...},
{title:'office',number:22222,...}]
}
sends
{ Id: 1,
name:'john',
phones:[object object]
phones:[object object]
}
Here is another choice: Chaosreader
So I need to debug an application which posts xml to a 3rd party application. I found a brilliant little perl script which does all the hard work – you just chuck it a tcpdump output file, and it does all the manipulation and outputs everything you need...
The script is called chaosreader0.94. See http://www.darknet.org.uk/2007/11/chaosreader-trace-tcpudp-sessions-from-tcpdump/
It worked like a treat, I did the following:
tcpdump host www.blah.com -s 9000 -w outputfile; perl chaosreader0.94 outputfile
Addition to above all simplified responses.
If you are working with files in bash script, it's better to use file descriptor.
For example: If you want to read and write from/to the file "test.txt", use the file descriptor as show below:
FILE=$1 # give the name of file in the command line
exec 5<>$FILE # '5' here act as the file descriptor
# Reading from the file line by line using file descriptor
while read LINE; do
echo "$LINE"
done <&5
# Writing to the file using descriptor
echo "Adding the date: `date`" >&5
exec 5<&- # Closing a file descriptor
