If you are producing the DataTable from an SQL query, have you considered simply using Dapper instead?
Then, instead of making a SqlCommand with SqlParameters and a DataTable and a DataAdapter and on and on, which you then have to laboriously convert to a class, you just define the class, make the query column names match the field names, and the parameters are bound easily by name. You already have the TankReading class defined, so it will be really simple!
using Dapper;
// Below can be SqlConnection cast to DatabaseConnection, too.
DatabaseConnection connection = // whatever
IEnumerable<TankReading> tankReadings = connection.Query<TankReading>(
"SELECT * from TankReading WHERE Value = @value",
new { value = "tank1" } // note how `value` maps to `@value`
);
return tankReadings;
Now isn't that awesome? Dapper is very optimized and will give you darn near equivalent performance as reading directly with a DataAdapter.
If your class has any logic in it at all or is immutable or has no parameterless constructor, then you probably do need to have a DbTankReading class (as a pure POCO/Plain Old Class Object):
// internal because it should only be used in the data source project and not elsewhere
internal sealed class DbTankReading {
int TankReadingsID { get; set; }
DateTime? ReadingDateTime { get; set; }
int ReadingFeet { get; set; }
int ReadingInches { get; set; }
string MaterialNumber { get; set; }
string EnteredBy { get; set; }
decimal ReadingPounds { get; set; }
int MaterialID { get; set; }
bool Submitted { get; set; }
}
You'd use that like this:
IEnumerable<TankReading> tankReadings = connection
.Query<DbTankReading>(
"SELECT * from TankReading WHERE Value = @value",
new { value = "tank1" } // note how `value` maps to `@value`
)
.Select(tr => new TankReading(
tr.TankReadingsID,
tr.ReadingDateTime,
tr.ReadingFeet,
tr.ReadingInches,
tr.MaterialNumber,
tr.EnteredBy,
tr.ReadingPounds,
tr.MaterialID,
tr.Submitted
});
Despite the mapping work, this is still less painful than the data table method. This also lets you perform some kind of logic, though if the logic is any more than very simple straight-across mapping, I'd put the logic into a separate TankReadingMapper class.
Two options (at least):
Note: linking the jar can lead to problems with the server and maybe the reason why it's added to the build path but not solving the server startup problem.
So don't point the jar to an external folder.
OR...
If you're using a tc server instance, then you need to add the jar as an external jar to the server instance run configurations.
go to run as, run configurations..., {your tc server instance}, and then the Class Path tab.
Then add the commons-logging jar.
The simple code that I am using:
public static long CurrentTimestamp()
{
return (long)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds * 1000);
}
This code is giving unix timestamp, total milliseconds from 1970-01-01 to now.
<?php
if (!preg_match("/^(http|ftp):/", $_POST['url'])) {
$_POST['url'] = 'http://'.$_POST['url'];
}
$url = $_POST['url'];
?>
This code will add http:// to the URL if it’s not there.

I hope that is the solution you're looking for! DEMO1 DEMO2
With that solution the only scrollbar in the page is on your contents section in the middle! In that section build your structure with a sidebar or whatever you want!
You can do that with that code here:
<div class="navTop">
<h1>Title</h1>
<nav>Dynamic menu</nav>
</div>
<div class="container">
<section>THE CONTENTS GOES HERE</section>
</div>
<footer class="bottomFooter">
Footer
</footer>
With that css:
.navTop{
width:100%;
border:1px solid black;
float:left;
}
.container{
width:100%;
float:left;
overflow:scroll;
}
.bottomFooter{
float:left;
border:1px solid black;
width:100%;
}
And a bit of jquery:
$(document).ready(function() {
function setHeight() {
var top = $('.navTop').outerHeight();
var bottom = $('footer').outerHeight();
var totHeight = $(window).height();
$('section').css({
'height': totHeight - top - bottom + 'px'
});
}
$(window).on('resize', function() { setHeight(); });
setHeight();
});

Here is a link to VeriSign's SSL Certificate Installation Checker: https://knowledge.verisign.com/support/ssl-certificates-support/index?page=content&id=AR1130
Enter your URL, click "Test this Web Server" and it will tell you if there are issues with your intermediate certificate authority.
That character is the BOM or "Byte Order Mark". It is usually received as the first few bytes of a file, telling you how to interpret the encoding of the rest of the data. You can simply remove the character to continue. Although, since the error says you were trying to convert to 'ascii', you should probably pick another encoding for whatever you were trying to do.
I suspect doSome returns this, which is myObj, which also has a then method. Standard method chaining...
if doSome is not returning this, being the object on which doSome was executed, rest assured it is returning some object with a then method...
as @patrick points out, there is no then() for standard js
This basic function handles swapping array keys and keeping the array in the original order...
public function keySwap(array $resource, array $keys)
{
$newResource = [];
foreach($resource as $k => $r){
if(array_key_exists($k,$keys)){
$newResource[$keys[$k]] = $r;
}else{
$newResource[$k] = $r;
}
}
return $newResource;
}
You could then loop through and swap all 'a' keys with 'z' for example...
$inputs = [
0 => ['a'=>'1','b'=>'2'],
1 => ['a'=>'3','b'=>'4']
]
$keySwap = ['a'=>'z'];
foreach($inputs as $k=>$i){
$inputs[$k] = $this->keySwap($i,$keySwap);
}
There are several key differences.
update is used on a queryset, so it is possible to update multiple objects at once.
As @FallenAngel pointed out, there are differences in how custom save() method triggers, but it is also important to keep in mind signals and ModelManagers. I have build a small testing app to show some valuable differencies. I am using Python 2.7.5, Django==1.7.7 and SQLite, note that the final SQLs may vary on different versions of Django and different database engines.
Ok, here's the example code.
models.py:
from __future__ import print_function
from django.db import models
from django.db.models import signals
from django.db.models.signals import pre_save, post_save
from django.dispatch import receiver
__author__ = 'sobolevn'
class CustomManager(models.Manager):
def get_queryset(self):
super_query = super(models.Manager, self).get_queryset()
print('Manager is called', super_query)
return super_query
class ExtraObject(models.Model):
name = models.CharField(max_length=30)
def __unicode__(self):
return self.name
class TestModel(models.Model):
name = models.CharField(max_length=30)
key = models.ForeignKey('ExtraObject')
many = models.ManyToManyField('ExtraObject', related_name='extras')
objects = CustomManager()
def save(self, *args, **kwargs):
print('save() is called.')
super(TestModel, self).save(*args, **kwargs)
def __unicode__(self):
# Never do such things (access by foreing key) in real life,
# because it hits the database.
return u'{} {} {}'.format(self.name, self.key.name, self.many.count())
@receiver(pre_save, sender=TestModel)
@receiver(post_save, sender=TestModel)
def reicever(*args, **kwargs):
print('signal dispatched')
views.py:
def index(request):
if request and request.method == 'GET':
from models import ExtraObject, TestModel
# Create exmple data if table is empty:
if TestModel.objects.count() == 0:
for i in range(15):
extra = ExtraObject.objects.create(name=str(i))
test = TestModel.objects.create(key=extra, name='test_%d' % i)
test.many.add(test)
print test
to_edit = TestModel.objects.get(id=1)
to_edit.name = 'edited_test'
to_edit.key = ExtraObject.objects.create(name='new_for')
to_edit.save()
new_key = ExtraObject.objects.create(name='new_for_update')
to_update = TestModel.objects.filter(id=2).update(name='updated_name', key=new_key)
# return any kind of HttpResponse
That resuled in these SQL queries:
# to_edit = TestModel.objects.get(id=1):
QUERY = u'SELECT "main_testmodel"."id", "main_testmodel"."name", "main_testmodel"."key_id"
FROM "main_testmodel"
WHERE "main_testmodel"."id" = %s LIMIT 21'
- PARAMS = (u'1',)
# to_edit.save():
QUERY = u'UPDATE "main_testmodel" SET "name" = %s, "key_id" = %s
WHERE "main_testmodel"."id" = %s'
- PARAMS = (u"'edited_test'", u'2', u'1')
# to_update = TestModel.objects.filter(id=2).update(name='updated_name', key=new_key):
QUERY = u'UPDATE "main_testmodel" SET "name" = %s, "key_id" = %s
WHERE "main_testmodel"."id" = %s'
- PARAMS = (u"'updated_name'", u'3', u'2')
We have just one query for update() and two for save().
Next, lets talk about overriding save() method. It is called only once for save() method obviously. It is worth mentioning, that .objects.create() also calls save() method.
But update() does not call save() on models. And if no save() method is called for update(), so the signals are not triggered either. Output:
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
# TestModel.objects.get(id=1):
Manager is called [<TestModel: edited_test new_for 0>]
Manager is called [<TestModel: edited_test new_for 0>]
save() is called.
signal dispatched
signal dispatched
# to_update = TestModel.objects.filter(id=2).update(name='updated_name', key=new_key):
Manager is called [<TestModel: edited_test new_for 0>]
As you can see save() triggers Manager's get_queryset() twice. When update() only once.
Resolution. If you need to "silently" update your values, without save() been called - use update. Usecases: last_seen user's field. When you need to update your model properly use save().
I can't see why you would care. Other than the "don't use ports below 1024" privilege rule, you should be able to use any port because your clients should be configurable to talk to any IP address and port!
If they're not, then they haven't been done very well. Go back and do them properly :-)
In other words, run the server at IP address X and port Y then configure clients with that information. Then, if you find you must run a different server on X that conflicts with your Y, just re-configure your server and clients to use a new port. This is true whether your clients are code, or people typing URLs into a browser.
I, like you, wouldn't try to get numbers assigned by IANA since that's supposed to be for services so common that many, many environments will use them (think SSH or FTP or TELNET).
Your network is your network and, if you want your servers on port 1234 (or even the TELNET or FTP ports for that matter), that's your business. Case in point, in our mainframe development area, port 23 is used for the 3270 terminal server which is a vastly different beast to telnet. If you want to telnet to the UNIX side of the mainframe, you use port 1023. That's sometimes annoying if you use telnet clients without specifying port 1023 since it hooks you up to a server that knows nothing of the telnet protocol - we have to break out of the telnet client and do it properly:
telnet big_honking_mainframe_box.com 1023
If you really can't make the client side configurable, pick one in the second range, like 48042, and just use it, declaring that any other software on those boxes (including any added in the future) has to keep out of your way.
Finally, I find the solution.
We can find there really exists the table 'pma__tracking' when we expand the phpmyadmin database.
But the system error call on #1932 - Table 'phpmyadmin.pma__tracking' doesn't exist in engine.
So just try to remove the old pma__* database first and reconfig them later.
1.Remove the wrong tables in xampp's installation path and remove all the files in var/mysql/phpmyadmin/, which are similar like pma__bookmark.frm/pma__bookmark.ibd...
2.Reinstall the sql of phpmyadmin, which located in phpmyadmin/sql/, something like 'create_tables.sql', run them with mysql < create_table.sql, etc.
Then it works.
To expand on Sparr's answer
Initialization and assignment are two distinct operations that happen to use the same operator ("=") here.
Think of it like this:
Imagine that there are 2 functions, called InitializeObject, and AssignObject. When the compiler sees thing = value, it looks at the context and calls one InitializeObject if you're making a new thing. If you're not, it instead calls AssignObject.
Normally this is fine as InitializeObject and AssignObject usually behave the same way. Except when dealing with char arrays (and a few other edge cases) in which case they behave differently. Why do this? Well that's a whole other post involving the stack vs the heap and so on and so forth.
PS: As an aside, thinking of it in this way will also help you understand copy constructors and other such things if you ever venture into C++
You must use some of the C # conversion systems:
string to boolean: True to true
string str = "True";
bool mybool = System.Convert.ToBoolean(str);
boolean to string: true to True
bool mybool = true;
string str = System.Convert.ToString(mybool);
//or
string str = mybool.ToString();
bool.Parse expects one parameter which in this case is str, even .
Convert.ToBoolean expects one parameter.
bool.TryParse expects two parameters, one entry (str) and one out (result).
If TryParse is true, then the conversion was correct, otherwise an error occurred
string str = "True";
bool MyBool = bool.Parse(str);
//Or
string str = "True";
if(bool.TryParse(str, out bool result))
{
//Correct conversion
}
else
{
//Incorrect, an error has occurred
}
Not saying this is the best approach, but it seems to work for me.
The full code may be found at: Example code at: https://github.com/dbleicher/recyclerview-grid-quickreturn
First off, add the expanded area to your cell/item layout, and make the enclosing cell layout animateLayoutChanges="true". This will ensure that the expand/collapse is animated:
<LinearLayout
android:id="@+id/llCardBack"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@android:color/white"
android:animateLayoutChanges="true"
android:padding="4dp"
android:orientation="vertical">
<TextView
android:id="@+id/tvTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|fill_horizontal"
android:padding="10dp"
android:gravity="center"
android:background="@android:color/holo_green_dark"
android:text="This is a long title to show wrapping of text in the view."
android:textColor="@android:color/white"
android:textSize="16sp" />
<TextView
android:id="@+id/tvSubTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|fill_horizontal"
android:background="@android:color/holo_purple"
android:padding="6dp"
android:text="My subtitle..."
android:textColor="@android:color/white"
android:textSize="12sp" />
<LinearLayout
android:id="@+id/llExpandArea"
android:visibility="gone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:text="Item One" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:text="Item Two" />
</LinearLayout>
</LinearLayout>
Then, make your RV Adapter class implement View.OnClickListener so that you can act on the item being clicked. Add an int field to hold the position of the one expanded view, and initialize it to a negative value:
private int expandedPosition = -1;
Finally, implement your ViewHolder, onBindViewHolder() methods and override the onClick() method. You will expand the view in onBindViewHolder if it's position is equal to "expandedPosition", and hide it if not. You set the value of expandedPosition in the onClick listener:
@Override
public void onBindViewHolder(RVAdapter.ViewHolder holder, int position) {
int colorIndex = randy.nextInt(bgColors.length);
holder.tvTitle.setText(mDataset.get(position));
holder.tvTitle.setBackgroundColor(bgColors[colorIndex]);
holder.tvSubTitle.setBackgroundColor(sbgColors[colorIndex]);
if (position == expandedPosition) {
holder.llExpandArea.setVisibility(View.VISIBLE);
} else {
holder.llExpandArea.setVisibility(View.GONE);
}
}
@Override
public void onClick(View view) {
ViewHolder holder = (ViewHolder) view.getTag();
String theString = mDataset.get(holder.getPosition());
// Check for an expanded view, collapse if you find one
if (expandedPosition >= 0) {
int prev = expandedPosition;
notifyItemChanged(prev);
}
// Set the current position to "expanded"
expandedPosition = holder.getPosition();
notifyItemChanged(expandedPosition);
Toast.makeText(mContext, "Clicked: "+theString, Toast.LENGTH_SHORT).show();
}
/**
* Create a ViewHolder to represent your cell layout
* and data element structure
*/
public static class ViewHolder extends RecyclerView.ViewHolder {
TextView tvTitle;
TextView tvSubTitle;
LinearLayout llExpandArea;
public ViewHolder(View itemView) {
super(itemView);
tvTitle = (TextView) itemView.findViewById(R.id.tvTitle);
tvSubTitle = (TextView) itemView.findViewById(R.id.tvSubTitle);
llExpandArea = (LinearLayout) itemView.findViewById(R.id.llExpandArea);
}
}
This should expand only one item at a time, using the system-default animation for the layout change. At least it works for me. Hope it helps.
Although probably not the best method you could add:
#div1 {
...
font-size:0;
}
If you just call exit in Bash without any parameters, it will return the exit code of the last command. Combined with OR, Bash should only invoke exit, if the previous command fails. But I haven't tested this.
command1 || exit; command2 || exit;
Bash will also store the exit code of the last command in the variable $?.
Does your script reference /bin/bash or /bin/sh in its hash bang line? The default system shell in Ubuntu is dash, not bash, so if you have #!/bin/sh then your script will be using a different shell than you expect. Dash does not have the <<< redirection operator.
combine https://stackoverflow.com/a/51837876/1078784 and answers in this question, I think the best answer is:
cat {SQL FILE NAME} | docker exec -i {MYSQL CONTAINER NAME} {MYSQL PATH IN CONTAINER} --init-command="SET autocommit=0;"
for example in my system this command should look like:
cat temp.sql | docker exec -i mysql.master /bin/mysql --init-command="SET autocommit=0;"
also you can use pv to moniter progress:
cat temp.sql | pv | docker exec -i mysql.master /bin/mysql --init-command="SET autocommit=0;"
And the most important thing here is "--init-command" which will speed up the import progress 10 times fast.
You can use something like ini_set('session.gc_maxlifetime', 28800); // 8 * 60 * 60 too.
When you use count = count + 3 or count = count + 9 instead of count = count + 1, the value of count will never be 100, and hence it enters an infinite loop.
You could use the following code for your condition to work
while count < 100:
Now the loop will terminate when count >= 100.
Workbooks.open("E:\sarath\PTMetrics\20131004\D8 L538-L550 16MY\D8 L538-L550_16MY_Powertrain Metrics_20131002.xlsm")
Or, in a more structured way...
Sub openwb()
Dim sPath As String, sFile As String
Dim wb As Workbook
sPath = "E:\sarath\PTMetrics\20131004\D8 L538-L550 16MY\"
sFile = sPath & "D8 L538-L550_16MY_Powertrain Metrics_20131002.xlsm"
Set wb = Workbooks.Open(sFile)
End Sub

el.dispatchEvent(e);

There are lots of explanation of Jmeter Summary, I have been using this tool from quite some time for generating performance testing report with relevant data. The explanation available on below link is right from the field experience:
Jmeter:Understanding Summary Report
This is one of the most useful report generated by Jmeter to undertstand the load test result.
# Label: Name of HTTP sample request send to server
# Samples : This Captures the total number of samples pushed to server. Suppose you put a Loop Controller to run it 5 times this particular request and then 2 iteration(Called Loop Count in Thread Group)is set and load test is run for 100 users, then the count that will be displayed here .... 1*5*2 * 100 =1000. Total = total number of samples send to server during entire run.
# Average : It's an average response time for a particular http request. This response time is in millisecond, and an average for 5 loops in two iteration for 100 users. Total = Average of total average of samples, means add all averages for all samples and divide by number of samples
# Min : Minmum time spend by sample requests send for this label. The total equals to the minimum time across all samples.
# Max : Maximum tie spend by sample requests send for this label The total equals to the maxmimum time across all samples.
# Std. Dev. : Knowing the standard deviation of your data set tells you how densely the data points are clustered around the mean. The smaller the standard deviation, the more consistent the data. Standard deviation should be less than or equal to half of the average time for a label. If it is more than that, then it means that something is wrong. you need to figure out the problem and fix it. https://en.wikipedia.org/wiki/Standard_deviation Total is euqals to highest deviation across all samples.
# Error: Total percentage of erros found for a particular sample request. 0.0% shows that all requests completed successfully. Total equals to percentage of errors samples in all samples (Total Samples)
# Throughput: Hits/sec, or total number of request per unit of time(sec, mins, hr) send to server during test.
endTime = lastSampleStartTime + lastSampleLoadTime startTime = firstSampleStartTime converstion = unit time conversion value Throughput = Numrequests / ((endTime - startTime)*conversion)# KB/sec : Its mesuring throughput rate in Kilobytes per second.
# Avg. Bytes: Avegare of total bytes of data downloaded from server. Totals is average bytes across all samples.
Remove some of your textarea class like
<textarea name="Address" rows="3" class="input-text full-width" placeholder="Your Address" ></textarea>
To
<textarea name="Address" rows="3" class="full-width" placeholder="Your Address" ></textarea>
It's dependent on your template (Purchased Template).
The developer has included some JavaScript to get the value from correct object on UI,
but class like input-text just finds only $('input[type=text]'), that's why.
it will load ViewWillAppear everytime you open the view. above is the link to the picture View Controller Lifecycle.
viewWillAppear()—Called just before the view controller’s content view is added to the app’s view hierarchy. Use this method to trigger any operations that need to occur before the content view is presented onscreen. Despite the name, just because the system calls this method, it does not guarantee that the content view will become visible. The view may be obscured by other views or hidden. This method simply indicates that the content view is about to be added to the app’s view hierarchy.
If you don't care about legacy browsers:
if ( bank_holidays.indexOf( '06/04/2012' ) > -1 )
if you do care about legacy browsers, there is a shim available on MDN. Otherwise, jQuery provides an equivalent function:
if ( $.inArray( '06/04/2012', bank_holidays ) > -1 )
The subset command is not necessary. Just use data frame indexing
studentdata[studentdata$Drink == 'water',]
Read the warning from ?subset
This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.
for log file you may date to enter into text data. following code may help
# declaring variables
Logfile="logfile.txt"
MAIL_LOG="Message to print in log file"
Location="were is u want to store log file"
cd $Location
if [ -f $Logfile ]
then
echo "$MAIL_LOG " >> $Logfile
else
touch $Logfile
echo "$MAIL_LOG" >> $Logfile
fi
ouput: 2. Log file will be created in first run and keep on updating from next runs. In case log file missing in future run , script will create new log file.
just do this
try
{
//some code
try
{
int idNumber = function2();
}
finally
{
do stuff here....
}
}
catch(Exception e)
{//... perhaps something here}
For all intents and purposes the finally block will always execute. Now there are a couple of exceptions where it won't actually execute: task killing the program, and there is a fast fail security exception which kills the application instantly. Other than that, an exception will be thrown in function 2, the finally block will execute the needed code and then catch the exception in the outer catch block.
In my case (NET Core 3.1) I fixed it by giving it an AssemblyName tag in the ProjectGroup section of the project file. e.g.
<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
<PropertyGroup>
<TargetFramework>netcoreapp3.1</TargetFramework>
<UseWPF>true</UseWPF>
<AssemblyName>ProjectNameUsually</AssemblyName>
</PropertyGroup>
...
</Project>
This also fixed a problem it was having with the compiler not seeing a control by its x:Name in the code-behind.
I had the same problem, but setting windowSoftInputMode did not help, and I did not want to change the upper view to have isScrollContainer="false" because I wanted it to scroll.
My solution was to define the top location of the navigation tools instead of the bottom. I'm using Titanium, so I'm not sure exactly how this would translate to android. Defining the top location of the navigation tools view prevented the soft keyboard from pushing it up, and instead covered the nav controls like I wanted.
Running as admin didn't help me. (also got errors with syscall: rename)
Turns out this error can also occur if files are locked by Windows.
This can occur if :
Running as admin doesn't get around windows file locking.
I created a new project in VS2017 and then switched to VSCode to try to add more packages. After stopping the project from running and closing VS2017 it was able to complete without error
Disclaimer: I'm not exactly sure if this means running as admin isn't necessary, but try to avoid it if possible to avoid the possibility of some rogue package doing stuff it isn't meant to.
I had the same problem. The bar had the same background color. Try:
android:scrollbarThumbVertical="@android:color/black"
To access properties and methods of a parent class use the base keyword. So in your child class LoadData() method you would do this:
public class Child : Parent
{
public void LoadData()
{
base.MyMethod(); // call method of parent class
base.CurrentRow = 1; // set property of parent class
// other stuff...
}
}
Note that you would also have to change the access modifier of your parent MyMethod() to at least protected for the child class to access it.

value = [NSNumber numberWithFloat:self.sensativity];
[[NSUserDefaults standardUserDefaults] setObject:value forKey:@"sensativity"];
}
-(void)loadUserSettings{
NSNumber* value;
value = [[NSUserDefaults standardUserDefaults] objectForKey:@"sensativity"];
if(value == nil){
self.sensativity = 4.0;
}else{
self.sensativity = [value floatValue];
}
}
Treat everything as an object. Seems to work for me.
Update April 2013: Don't do this. It wasn't a good idea in 2009 when I first answered the question and it really isn't a good idea now. See this answer by hackbod for reasons:
Avoid reloading activity with asynctask on orientation change in android
Add android:configChanges="keyboardHidden|orientation" to your AndroidManifest.xml. This tells the system what configuration changes you are going to handle yourself - in this case by doing nothing.
<activity android:name="MainActivity"
android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation">
See Developer reference configChanges for more details.
However, your application can be interrupted at any time, e.g. by a phone call, so you really should add code to save the state of your application when it is paused.
Update: As of Android 3.2, you also need to add "screenSize":
<activity
android:name="MainActivity"
android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation|screenSize">
From Developer guide Handling the Configuration Change Yourself
Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must declare
android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).
To get the content of a directory you can use
$files = Get-ChildItem "C:\Users\gerhardl\Documents\My Received Files\"
Then you can loop over this variable as well:
for ($i=0; $i -lt $files.Count; $i++) {
$outfile = $files[$i].FullName + "out"
Get-Content $files[$i].FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}
An even easier way to put this is the foreach loop (thanks to @Soapy and @MarkSchultheiss):
foreach ($f in $files){
$outfile = $f.FullName + "out"
Get-Content $f.FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}
I will show you some example
First I extract the text data from the data frame (twitter_df) to process further as following
from nltk.tokenize import word_tokenize
tweetText = twitter_df['text']
Then to tokenize I use the following method
from nltk.tokenize import word_tokenize
tweetText = tweetText.apply(word_tokenize)
Then, to remove stop words,
from nltk.corpus import stopwords
nltk.download('stopwords')
stop_words = set(stopwords.words('english'))
tweetText = tweetText.apply(lambda x:[word for word in x if word not in stop_words])
tweetText.head()
I Think this will help you
Unfortunately if you're looking to apply UIPopoverController in iOS9, you'll get a deprecated class warning. Instead you need to set your desired view's UIModalPresentationPopover property to achieve the same result.
Popover
In a horizontally regular environment, a presentation style where the content is displayed in a popover view. The background content is dimmed and taps outside the popover cause the popover to be dismissed. If you do not want taps to dismiss the popover, you can assign one or more views to the passthroughViews property of the associated UIPopoverPresentationController object, which you can get from the popoverPresentationController property.
In a horizontally compact environment, this option behaves the same as UIModalPresentationFullScreen.
Available in iOS 8.0 and later.

Without your actual data or source, it will be hard for us to diagnose what is going wrong. However, I can make a few suggestions:
Given what you wrote, I suspect whatever converts the database data to XML is broken; it's propagating non-XML characters.
Create some database entries with non-XML characters (NULs, DELs, control characters, et al.) and run your XML converter on it. Output the XML to a file and look at it in a hex editor. If this contains non-XML characters, your converter is broken. Fix it or, if you cannot, create a preprocessor that rejects output with such characters.
If the converter output looks good, the problem is in your XML consumer; it's inserting non-XML characters somewhere. You will have to break your consumption process into separate steps, examine the output at each step, and narrow down what is introducing the bad characters.
Update: I just ran into an example of this myself! What was happening is that the producer was encoding the XML as UTF16 and the consumer was expecting UTF8. Since UTF16 uses 0x00 as the high byte for all ASCII characters and UTF8 doesn't, the consumer was seeing every second byte as a NUL. In my case I could change encoding, but suggested all XML payloads start with a BOM.
I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

To reduce verbosity, you can use a static import:
import static java.util.concurrent.TimeUnit.NANOSECONDS;
-and henceforth just type
NANOSECONDS.toSeconds(elapsedTime);
First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.
After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

I know it is always preferred not to hardcode the sudo password in the script. However, for some reason, if you have no permission to modify /etc/sudoers or change file owner, Pexpect is a feasible alternative.
Here is a Python function sudo_exec for your reference:
import platform, os, logging
import subprocess, pexpect
log = logging.getLogger(__name__)
def sudo_exec(cmdline, passwd):
osname = platform.system()
if osname == 'Linux':
prompt = r'\[sudo\] password for %s: ' % os.environ['USER']
elif osname == 'Darwin':
prompt = 'Password:'
else:
assert False, osname
child = pexpect.spawn(cmdline)
idx = child.expect([prompt, pexpect.EOF], 3)
if idx == 0: # if prompted for the sudo password
log.debug('sudo password was asked.')
child.sendline(passwd)
child.expect(pexpect.EOF)
return child.before
I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.
I had <meta http-equiv="x-ua-compatible" content="ie=edge"> on the page.
In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.
function resizeWindow(){
var evt = document.createEvent('UIEvents');
evt.initUIEvent('resize', true, false,window,0);
window.dispatchEvent(evt);
}
call this function after 500 milliseconds.
The exec function executes a system command and never returns-- use system instead of exec if you want it to return
Does exactly the same thing as exec LIST , except that a fork is done first, and the parent process waits for the child process to complete.
In contrast to exec and system, backticks don't give you the return value but the collected STDOUT.
A string which is (possibly) interpolated and then executed as a system command with /bin/sh or its equivalent. Shell wildcards, pipes, and redirections will be honored. The collected standard output of the command is returned; standard error is unaffected.
In more complex scenarios, where you want to fetch STDOUT, STDERR or the return code, you can use well known standard modules like IPC::Open2 and IPC::Open3.
Example:
use IPC::Open2;
my $pid = open2(\*CHLD_OUT, \*CHLD_IN, 'some', 'cmd', 'and', 'args');
waitpid( $pid, 0 );
my $child_exit_status = $? >> 8;
Finally, IPC::Run from the CPAN is also worth looking at…
The only character that needs escaping is <. (> is meaningless outside of a tag).
Therefore, your "magic" code is:
safestring = unsafestring.replace(/</g,'<');
Because you initialized the top variable to -1 in your constructor, you need to increment the top variable in your push() method before you access the array. Note that I've changed the assignment to use ++top:
public void push(int i)
{
if (top == stack.length)
{
extendStack();
}
stack[++top]= i;
}
That will fix the ArrayIndexOutOfBoundsException you posted about. I can see other issues in your code, but since this is a homework assignment I'll leave those as "an exercise for the reader." :)
The above given ans are correct and works fine. I used in a different way.

Inside template/twig file:

Ping is ICMP, but if there is any open TCP port on the remote server it could be achieved like this:
function ping(host, port, pong) {
var started = new Date().getTime();
var http = new XMLHttpRequest();
http.open("GET", "http://" + host + ":" + port, /*async*/true);
http.onreadystatechange = function() {
if (http.readyState == 4) {
var ended = new Date().getTime();
var milliseconds = ended - started;
if (pong != null) {
pong(milliseconds);
}
}
};
try {
http.send(null);
} catch(exception) {
// this is expected
}
}
Adding the sourceURL in the script file helped as mentioned in this page: https://blog.getfirebug.com/2009/08/11/give-your-eval-a-name-with-sourceurl/
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
class MultiArg {
Scanner sc;
int n;
String as;
List<Integer> numList = new ArrayList<Integer>();
public void fun() {
sc = new Scanner(System.in);
System.out.println("enter value");
while (sc.hasNextInt())
as = sc.nextLine();
}
public void diplay() {
System.out.println("x");
Integer[] num = numList.toArray(new Integer[numList.size()]);
System.out.println("show value " + as);
for (Integer m : num) {
System.out.println("\t" + m);
}
}
}
but to terminate the while loop you have to put any charecter at the end of input.
ex. input:
12 34 56 78 45 67 .
output:
12 34 56 78 45 67
I had an error with an array getting the max and the min so my solution was:
int max = Arrays.stream(arrayWithInts).max().getAsInt();
int min = Arrays.stream(arrayWithInts).min().getAsInt();
Simply PROJECTION deals with elimination or selection of columns, while SELECTION deals with elimination or selection of rows.
You need to read about Java Image API and mouse-related API, maybe somewhere under the java.awt.event package.
For a start, you need to be able to load and display the image to the screen, maybe you'll use a JPanel.
Then from there, you will try implement a mouse motion listener interface and other related interfaces. Maybe you'll get tied on the mouseDragged method...
For a mousedragged action, you will get the coordinate of the rectangle form by the drag...
Then from these coordinates, you will get the subimage from the image you have and you sort of redraw it anew....
And then display the cropped image... I don't know if this will work, just a product of my imagination... just a thought!
If you're using jQueryUI - there is an onDrag event. If you're not, then attach your listener to mouseup(), not click().
As others stated, it's likely failing because the requested key doesn't exist in the array. I have a helper function here that takes the array, the suspected key, as well as a default return in the event the key does not exist.
protected function _getArrayValue($array, $key, $default = null)
{
if (isset($array[$key])) return $array[$key];
return $default;
}
hope it helps.
Ideally, find a JSON library in your language that you can feed some appropriate data structure to, and let it worry about how to escape things. It'll keep you much saner. If for whatever reason you don't have a library in your language, you don't want to use one (I wouldn't suggest this¹), or you're writing a JSON library, read on.
Escape it according to the RFC. JSON is pretty liberal: The only characters you must escape are \, ", and control codes (anything less than U+0020).
This structure of escaping is specific to JSON. You'll need a JSON specific function. All of the escapes can be written as \uXXXX where XXXX is the UTF-16 code unit¹ for that character. There are a few shortcuts, such as \\, which work as well. (And they result in a smaller and clearer output.)
For full details, see the RFC.
¹JSON's escaping is built on JS, so it uses \uXXXX, where XXXX is a UTF-16 code unit. For code points outside the BMP, this means encoding surrogate pairs, which can get a bit hairy. (Or, you can just output the character directly, since JSON's encoded for is Unicode text, and allows these particular characters.)
Create a text node and append it to the button element:
var t = document.createTextNode("test content");
b.appendChild(t);
On some OS you get . .. and .DS_Store, Well we can't use them so let's us hide them.
First start get all information about the files, using scandir()
// Folder where you want to get all files names from
$dir = "uploads/";
/* Hide this */
$hideName = array('.','..','.DS_Store');
// Sort in ascending order - this is default
$files = scandir($dir);
/* While this to there no more files are */
foreach($files as $filename) {
if(!in_array($filename, $hideName)){
/* echo the name of the files */
echo "$filename<br>";
}
}
This problem can also come up when you don't have your constructor immediately call super.
So this will work:
public Employee(String name, String number, Date date)
{
super(....)
}
But this won't:
public Employee(String name, String number, Date date)
{
// an example of *any* code running before you call super.
if (number < 5)
{
number++;
}
super(....)
}
The reason the 2nd example fails is because java is trying to implicitely call
super(name,number,date)
as the first line in your constructor.... So java doesn't see that you've got a call to super going on later in the constructor. It essentially tries to do this:
public Employee(String name, String number, Date date)
{
super(name, number, date);
if (number < 5)
{
number++;
}
super(....)
}
So the solution is pretty easy... Just don't put code before your super call ;-) If you need to initialize something before the call to super, do it in another constructor, and then call the old constructor... Like in this example pulled from this StackOverflow post:
public class Foo
{
private int x;
public Foo()
{
this(1);
}
public Foo(int x)
{
this.x = x;
}
}
Adding a solution which I've recently used myself and haven't seen mentioned here. If you have Apache Commons Collections available then you can use the SetUtils#difference method:
// Returns all the elements of test2 which are not in test1
SetUtils.difference(test2, test1)
Note that according to the documentation the returned set is an unmodifiable view:
Returns a unmodifiable view containing the difference of the given Sets, denoted by a \ b (or a - b). The returned view contains all elements of a that are not a member of b.
Full documentation: https://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/SetUtils.html#difference-java.util.Set-java.util.Set-
Just to add, we can use array as well:
int i, array[4];
printf("Enter Four Ints: ");
for(i=0; i<4; i++) {
scanf("%d", &array[i]);
}
I had the same problem on two Arduinos (one Uno, and one Modern Device Freeduino/USB Host board) and the window between reset and the beginning of serial port usage was so small that it was impossible to upload.
I finally fixed the problem by purchasing another Arduino Uno and building an ISP cable per these instructions, and using it to flash the Bare Bones app from the examples into each inaccessible board, using Arduino IDE version 0023, following these instructions to change preferences.txt. (Be sure to save the original file before editing it so you can replace it after you've rescued your Arduino.)
It took one quick upload to fix each board. Such a fast fix after so much grief. You might not want to purchase another Arduino, but consider these benefits:

$.get does not give you the opportunity to set an error handler. You will need to use the low-level $.ajax function instead:
$.ajax({
url: 'http://example.com/page/2/',
type: 'GET',
success: function(data){
$(data).find('#reviews .card').appendTo('#reviews');
},
error: function(data) {
alert('woops!'); //or whatever
}
});
Edit March '10
Note that with the new jqXHR object in jQuery 1.5, you can set an error handler after calling $.get:
$.get('http://example.com/page/2/', function(data){
$(data).find('#reviews .card').appendTo('#reviews');
}).fail(function() {
alert('woops'); // or whatever
});
Run this from your server's command line:
mysqlcheck --repair --all-databases

set(h,'PaperUnits','centimeters');
set(h,'PaperSize',[9 6]); % IEEE columnwidth = 9cm
set(h,'Position',[0 0 9 6]);
% xpos, ypos must be set
txlabel = text(xpos,ypos,'$$[\mathrm{min}]$$','Interpreter','latex','FontSize',9);

Make sure that both projects have same target framework version here: right click on project -> properties -> application (tab) -> target framework
Also, make sure that the project "logger" (which you want to include in the main project) has the output type "Class Library" in: right click on project -> properties -> application (tab) -> output type
Finally, Rebuild the solution.
Basically, you have three options:
EXPOSE nor -pEXPOSEEXPOSE and -p1) If you specify neither EXPOSE nor -p, the service in the container will only be accessible from inside the container itself.
2) If you EXPOSE a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.
3) If you EXPOSE and -p a port, the service in the container is accessible from anywhere, even outside Docker.
The reason why both are separated is IMHO because:
The documentation explicitly states:
The
EXPOSEinstruction exposes ports for use within links.
It also points you to how to link containers, which basically is the inter-container communication I talked about.
PS: If you do -p, but do not EXPOSE, Docker does an implicit EXPOSE. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p includes EXPOSE. That's why I didn't list it above as a fourth case.
If you try to decrypt PKCS5-padded data with the wrong key, and then unpad it (which is done by the Cipher class automatically), you most likely will get the BadPaddingException (with probably of slightly less than 255/256, around 99.61%), because the padding has a special structure which is validated during unpad and very few keys would produce a valid padding.
So, if you get this exception, catch it and treat it as "wrong key".
This also can happen when you provide a wrong password, which then is used to get the key from a keystore, or which is converted into a key using a key generation function.
Of course, bad padding can also happen if your data is corrupted in transport.
That said, there are some security remarks about your scheme:
For password-based encryption, you should use a SecretKeyFactory and PBEKeySpec instead of using a SecureRandom with KeyGenerator. The reason is that the SecureRandom could be a different algorithm on each Java implementation, giving you a different key. The SecretKeyFactory does the key derivation in a defined manner (and a manner which is deemed secure, if you select the right algorithm).
Don't use ECB-mode. It encrypts each block independently, which means that identical plain text blocks also give always identical ciphertext blocks.
Preferably use a secure mode of operation, like CBC (Cipher block chaining) or CTR (Counter). Alternatively, use a mode which also includes authentication, like GCM (Galois-Counter mode) or CCM (Counter with CBC-MAC), see next point.
You normally don't want only confidentiality, but also authentication, which makes sure the message is not tampered with. (This also prevents chosen-ciphertext attacks on your cipher, i.e. helps for confidentiality.) So, add a MAC (message authentication code) to your message, or use a cipher mode which includes authentication (see previous point).
DES has an effective key size of only 56 bits. This key space is quite small, it can be brute-forced in some hours by a dedicated attacker. If you generate your key by a password, this will get even faster. Also, DES has a block size of only 64 bits, which adds some more weaknesses in chaining modes. Use a modern algorithm like AES instead, which has a block size of 128 bits, and a key size of 128 bits (for the standard variant).
I created a simple utility for measuring performance of blocks of code, using the chrono library's high_resolution_clock: https://github.com/nfergu/codetimer.
Timings can be recorded against different keys, and an aggregated view of the timings for each key can be displayed.
Usage is as follows:
#include <chrono>
#include <iostream>
#include "codetimer.h"
int main () {
auto start = std::chrono::high_resolution_clock::now();
// some code here
CodeTimer::record("mykey", start);
CodeTimer::printStats();
return 0;
}

You might find it better to use a 3rd party program to enter the queries into Access such as WinSQL I think from memory WinSQL supports multiple queries via it's batch feature.
I ultimately found it easier to just write a program in perl to do bulk INSERTS into an Access via ODBC. You could use vbscript or any language that supports ODBC though.
You can then do anything you like and have your own complicated logic to handle the importing.

# cgi-bin exists but is not a directory
}
else {
# nothing called cgi-bin exists
}
As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.
Depending on which database you're using...
select yr, count(*) num from ...
order by num desc
Most of my experience is in Sybase, which uses some different syntax than other DBs. But in this case, you're naming your count column, so you can sort it, descending order. You can go a step further, and restrict your results to the first 10 rows (to find his 10 busiest years).
You can use schemas in Access.

.Open strDBPath
End With
' Open the tables schema rowset.
Set rstList = cnnDB.OpenSchema(adSchemaTables)
' Loop through the results and print the

If anyone is curious on how to create a custom error and get the stack trace:
function CustomError(message) {
this.name = 'CustomError';
this.message = message || '';
var error = new Error(this.message);
error.name = this.name;
this.stack = error.stack;
}
CustomError.prototype = Object.create(Error.prototype);
try {
throw new CustomError('foobar');
}
catch (e) {
console.log('name:', e.name);
console.log('message:', e.message);
console.log('stack:', e.stack);
}
You can download the JAXB jar files from http://jaxb.java.net/2.2.5/ You don't need to install anything, just invoke the xjc command and with classpath argument pointing to the downloaded JAXB jar files.
uint16_t log2(uint32_t n) {//but truncated
if (n==0) throw ...
uint16_t logValue = -1;
while (n) {//
logValue++;
n >>= 1;
}
return logValue;
}
Basically the same as tomlogic's.
If you don't understand Windows Installer then I highly recommend The Definitive Guide to Windows Installer. You can't really use WiX without understanding MSI. Also worth downloading is the Windows Installer 4.5 SDK.
If you don't want to learn the Windows Installer fundamentals, then you'll need some wizard type package to hide all the nitty gritty details and hold your hand. There are plenty of options, some more expensive than others.
However still I'd suggest picking up the above book and taking some time to understand what's going on "under the hood", it'll really help you figure out what's going wrong when customers start complaining that something is broken with the setup :)
This solution checks all the possible formats before throwing an exception. This solution is more convenient if you are trying to test for multiple date formats.
Date extractTimestampInput(String strDate){
final List<String> dateFormats = Arrays.asList("yyyy-MM-dd HH:mm:ss.SSS", "yyyy-MM-dd");
for(String format: dateFormats){
SimpleDateFormat sdf = new SimpleDateFormat(format);
try{
return sdf.parse(strDate);
} catch (ParseException e) {
//intentionally empty
}
}
throw new IllegalArgumentException("Invalid input for date. Given '"+strDate+"', expecting format yyyy-MM-dd HH:mm:ss.SSS or yyyy-MM-dd.");
}
I really liked @StevePaul's answer but we can do the same without extraneous subscribe/unsubscribe call.
import { ActivatedRoute } from '@angular/router';
constructor(private activatedRoute: ActivatedRoute) {
let params: any = this.activatedRoute.snapshot.params;
console.log(params.id);
// or shortcut Type Casting
// (<any> this.activatedRoute.snapshot.params).id
}
I can see that this only for actually turning the dialogs back on. But if you are a web dev and you would like to see a way to possibly have some form of notification when these are off...in the case that you are using native alerts/confirms for validation or whatever. Check this solution to detect and notify the user https://stackoverflow.com/a/23697435/1248536
There are a few steps you need to take to properly store this information in your localStorage. Before we get down to the code however, please note that localStorage (at the current time) cannot hold any data type except for strings. You will need to serialize the array for storage and then parse it back out to make modifications to it.
Step 1:
The First code snippet below should only be run if you are not already storing a serialized array in your localStorage session variable.
To ensure your localStorage is setup properly and storing an array, run the following code snippet first:
var a = [];
a.push(JSON.parse(localStorage.getItem('session')));
localStorage.setItem('session', JSON.stringify(a));
The above code should only be run once and only if you are not already storing an array in your localStorage session variable. If you are already doing this skip to step 2.
Step 2:
Modify your function like so:
function SaveDataToLocalStorage(data)
{
var a = [];
// Parse the serialized data back into an aray of objects
a = JSON.parse(localStorage.getItem('session')) || [];
// Push the new data (whether it be an object or anything else) onto the array
a.push(data);
// Alert the array value
alert(a); // Should be something like [Object array]
// Re-serialize the array back into a string and store it in localStorage
localStorage.setItem('session', JSON.stringify(a));
}
This should take care of the rest for you. When you parse it out, it will become an array of objects.
Hope this helps.
I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.
Just remember that .equals(...) has to be implemented by the class you are trying to compare. Otherwise, there isn't much of a point; the version of the method for the Object class does the same thing as the comparison operation: Object#equals.
The only time you really want to use the comparison operator for objects is wen you are comparing Enums. This is because there is only one instance of an Enum value at a time. For instance, given the enum
enum FooEnum {A, B, C}
You will never have more than one instance of A at a time, and the same for B and C. This means that you can actually write a method like so:
public boolean compareFoos(FooEnum x, FooEnum y)
{
return (x == y);
}
And you will have no problems whatsoever.
You cannot create a table with a name that is identical to an existing table or view in the cluster. To modify an existing table, use ALTER TABLE (link), or to drop all data currently in the table and create an empty table with the desired schema, issue DROP TABLE before CREATE TABLE.
It could be that the sequence you are creating is the culprit. In PostgreSQL, sequences are implemented as a table with a particular set of columns. If you already have the sequence defined, you should probably skip creating it. Unfortunately, there's no equivalent in CREATE SEQUENCE to the IF NOT EXISTS construct available in CREATE TABLE. By the looks of it, you might be creating your schema unconditionally, anyways, so it's reasonable to use
DROP TABLE IF EXISTS csd_relationship;
DROP SEQUENCE IF EXISTS csd_relationship_csd_relationship_id_seq;
before the rest of your schema update; In case it isn't obvious, This will delete all of the data in the csd_relationship table, if there is any

There are several problems here:
The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.
The predictor variable needs to be passed in as a named column in a data frame, so that
predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).
For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).
With those changes incorporated, this will work:
model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")
If it still actual for someone, my solution was as follows:
.container{
overflow: hidden;
overflow-y: auto;
}
Observer-Observable: it is used in ApplicationContext's event mechanism
ngOnInit() is called after ngOnChanges() was called the first time. ngOnChanges() is called every time inputs are updated by change detection.
ngAfterViewInit() is called after the view is initially rendered. This is why @ViewChild() depends on it. You can't access view members before they are rendered.
Use "&" instead of "&".
The new and delete operators can operate on classes and structures, whereas malloc and free only work with blocks of memory that need to be cast.
Using new/delete will help to improve your code as you will not need to cast allocated memory to the required data structure.
Assuming your current remote is named origin then:
Delete the current remote reference with
git remote rm origin
Add the new remote
git remote add origin <URL to new heroku app>
push to new domain
git push -u origin master
The -u will set this up as tracked.
There are many ways you can import Text file to the current sheet. Here are three (including the method that you are using above)
Cells.CopyUsing a QueryTable
Here is a simple macro that I recorded. Please amend it to suit your needs.
Sub Sample()
With ActiveSheet.QueryTables.Add(Connection:= _
"TEXT;C:\Sample.txt", Destination:=Range("$A$1") _
)
.Name = "Sample"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.RefreshStyle = xlInsertDeleteCells
.SavePassword = False
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.TextFilePromptOnRefresh = False
.TextFilePlatform = 437
.TextFileStartRow = 1
.TextFileParseType = xlDelimited
.TextFileTextQualifier = xlTextQualifierDoubleQuote
.TextFileConsecutiveDelimiter = False
.TextFileTabDelimiter = True
.TextFileSemicolonDelimiter = False
.TextFileCommaDelimiter = True
.TextFileSpaceDelimiter = False
.TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1)
.TextFileTrailingMinusNumbers = True
.Refresh BackgroundQuery:=False
End With
End Sub
Open the text file in memory
Sub Sample()
Dim MyData As String, strData() As String
Open "C:\Sample.txt" For Binary As #1
MyData = Space$(LOF(1))
Get #1, , MyData
Close #1
strData() = Split(MyData, vbCrLf)
End Sub
Once you have the data in the array you can export it to the current sheet.
Using the method that you are already using
Sub Sample()
Dim wbI As Workbook, wbO As Workbook
Dim wsI As Worksheet
Set wbI = ThisWorkbook
Set wsI = wbI.Sheets("Sheet1") '<~~ Sheet where you want to import
Set wbO = Workbooks.Open("C:\Sample.txt")
wbO.Sheets(1).Cells.Copy wsI.Cells
wbO.Close SaveChanges:=False
End Sub
FOLLOWUP
You can use the Application.GetOpenFilename to choose the relevant file. For example...
Sub Sample()
Dim Ret
Ret = Application.GetOpenFilename("Prn Files (*.prn), *.prn")
If Ret <> False Then
With ActiveSheet.QueryTables.Add(Connection:= _
"TEXT;" & Ret, Destination:=Range("$A$1"))
'~~> Rest of the code
End With
End If
End Sub
In addition to romkyns's great answer.. here is some relevant documentation/examples.
DOM Elements have a native .click() method.
The
HTMLElement.click()method simulates a mouse click on an element.When click is used, it also fires the element's click event which will bubble up to elements higher up the document tree (or event chain) and fire their click events too. However, bubbling of a click event will not cause an
<a>element to initiate navigation as if a real mouse-click had been received. (mdn reference)
Relevant W3 documentation.
A few examples..
You can access a specific DOM element from a jQuery object: (example)
$('a')[0].click();
You can use the .get() method to retrieve a DOM element from a jQuery object: (example)
$('a').get(0).click();
As expected, you can select the DOM element and call the .click() method. (example)
document.querySelector('a').click();
It's worth pointing out that jQuery is not required to trigger a native .click() event.

Put this code in a Module in VBA (Developer Tab -> Visual Basic)
Dim TimerActive As Boolean
Sub StartTimer()
Start_Timer
End Sub
Private Sub Start_Timer()
TimerActive = True
Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
End Sub
Private Sub Stop_Timer()
TimerActive = False
End Sub
Private Sub Timer()
If TimerActive Then
ActiveSheet.Cells(1, 1).Value = Time
Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
End If
End Sub
You can invoke the "StartTimer" function when the workbook opens and have it repeat every minute by adding the below code to your workbooks Visual Basic "This.Workbook" class in the Visual Basic editor.
Private Sub Workbook_Open()
Module1.StartTimer
End Sub
Now, every time 1 minute passes the Timer procedure will be invoked, and set cell A1 equal to the current time.

I use CTEs to help compose complicated SQL queries but not all RDBMS' support them. You can think of them as query scope views. Here is an example in t-sql on SQL server.
With localView1 as (
select c1,
c2,
c3,
c4,
((c2-c4)*(3))+c1 as "complex"
from realTable1)
, localView2 as (
select case complex WHEN 0 THEN 'Empty' ELSE 'Not Empty' end as formula1,
complex * complex as formula2
from localView1)
select *
from localView2
private Object lock = new Object();
private volatile boolean isOdd = false;
public void generateEvenNumbers(int number) throws InterruptedException {
synchronized (lock) {
while (isOdd == false)
{
lock.wait();
}
System.out.println(number);
isOdd = false;
lock.notifyAll();
}
}
public void generateOddNumbers(int number) throws InterruptedException {
synchronized (lock) {
while (isOdd == true) {
lock.wait();
}
System.out.println(number);
isOdd = true;
lock.notifyAll();
}
}
I used this method that I created when I was 14 years old.
public static int gcd (int a, int b) {
int s = 1;
int ia = Math.abs(a);//<-- turns to absolute value
int ib = Math.abs(b);
if (a == b) {
s = a;
}else {
while (ib != ia) {
if (ib > ia) {
s = ib - ia;
ib = s;
}else {
s = ia - ib;
ia = s;
}
}
}
return s;
}
Actually in C, you don't have an power operator. You will need to manually run a loop to get the result. Even the exp function just operates in that way only. But if you need to use that function, include the following header
#include <math.h>
then you can use pow().
This should also work (even in SQL-Server 2005):
SELECT *
FROM dbo.MyTable
WHERE Created >= DATEADD(hh,23,DATEADD(day, DATEDIFF(day, 0, Created - 1), 0))
AND Created < DATEADD(hh,7,DATEADD(day, DATEDIFF(day, 0, Created), 0))
@thomax 's answer is pretty good, but will fail if the first element in the array is false or false-y (0, empty string, etc.). Better to just return true for anything other than undefined:
const arr = [];
arr[1] = '';
arr[2] = 'foo';
const first = arr.find((v) => { return (typeof v !== 'undefined'); });
console.log(first); // ''
Not OP's answer but as this was the first question that popped up for me in google, Id also like to add that users searching for this might need to reseed their table, which was the case for me

For input elements, this answer works for me.
I implemented it on a custom input component in Angular 4, but I think it could be implemented with pure JS.
HTML
<input type="text" [(ngModel)]="value" (ondragenter)="disableEvent($event)"
(dragover)="disableEvent($event)" (ondrop)="disableEvent($event)"/>
Component definition (JS):
export class CustomInputComponent {
//component construction and attribute definitions
disableEvent(event) {
event.preventDefault();
return false;
}
}
How about something as simple as:
function negative(number){
return number < 0;
}
The * 1 part is to convert strings to numbers.
Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.
Here's how to do it for Internet Explorer:
function copy (str)
{
//for IE ONLY!
window.clipboardData.setData('Text',str);
}
As the compiler says, grid was not declared in the scope of your function :) "Scope" basically means a set of curly braces. Every variable is limited to the scope in which it is declared (it cannot be accessed outside that scope). In your case, you're declaring the grid variable in your main() function and trying to use it in nonrecursivecountcells(). You seem to be passing it as the argument colors however, so I suggest you just rename your uses of grid in nonrecursivecountcells() to colors. I think there may be something wrong with trying to pass the array that way, too, so you should probably investigate passing it as a pointer (unless someone else says something to the contrary).
I was also thinking of media queries, but then I found this:
Just create a wrapper <div> with a percentage value for padding-bottom, like this:
div {_x000D_
width: 100%;_x000D_
padding-bottom: 75%;_x000D_
background:gold; /** <-- For the demo **/_x000D_
}<div></div>It will result in a <div> with height equal to 75% of the width of its container (a 4:3 aspect ratio).
This technique can also be coupled with media queries and a bit of ad hoc knowledge about page layout for even more finer-grained control.
It's enough for my needs. Which might be enough for your needs too.
Here is how I solved the same problem using the Oracle.DataAccess.Client Namespace.
using Oracle.DataAccess.Client;
string strConnection = ConfigurationManager.ConnectionStrings["oConnection"].ConnectionString;
dataConnection = new OracleConnectionStringBuilder(strConnection);
OracleConnection oConnection = new OracleConnection(dataConnection.ToString());
oConnection.Open();
OracleCommand tmpCommand = oConnection.CreateCommand();
tmpCommand.Parameters.Add("user", OracleDbType.Varchar2, txtUser.Text, ParameterDirection.Input);
tmpCommand.CommandText = "SELECT USER, PASS FROM TB_USERS WHERE USER = :1";
try
{
OracleDataReader tmpReader = tmpCommand.ExecuteReader(CommandBehavior.SingleRow);

There is an odd way to do this with xcopy:
echo nnnnnnnnnnn | xcopy /-y source target
Just include as many n's as files you're copying, and it will answer n to all of the overwrite questions.
try {
java.util.Collections.sort(data,
new Comparator<Map<String, String>>() {
SimpleDateFormat sdf = new SimpleDateFormat(
"MM/dd/yyyy");
public int compare(final Map<String, String> map1,
final Map<String, String> map2) {
Date date1 = null, date2 = null;
try {
date1 = sdf.parse(map1.get("Date"));
date2 = sdf.parse(map2.get("Date"));
} catch (ParseException e) {
e.printStackTrace();
}
if (date1.compareTo(date2) > 0) {
return +1;
} else if (date1.compareTo(date2) == 0) {
return 0;
} else {
return -1;
}
}
});
} catch (Exception e) {
}
You can also use findIndex and pick to achieve the same result:
var arr = [{id: 1, name: "Person 1"}, {id:2, name:"Person 2"}];
var data = {id: 2, name: 'Person 2 (updated)'};
var index = _.findIndex(arr, _.pick(data, 'id'));
if( index !== -1) {
arr.splice(index, 1, data);
} else {
arr.push(data);
}
If by saying without destroying it, you mean to a keep a reference to the children, you can do:
var oldChildren = [];
while(element.hasChildNodes()) {
oldChildren.push(element.removeChild(element.firstChild));
}
Regarding the original tagging (html css) of your question:
You cannot remove content with CSS. You could only hide it. E.g. you can hide all children of a certain node with:
#someID > * {
display: none;
}
This doesn't work in IE6 though (but you could use #someID *).
"most convenient block of data" probably refers to the width (in bits) of the WORD, in correspondance to the system bus width, or whatever underlying "bandwidth" is available. On a 16 bit system, with WORD being defined as 16 bits wide, moving data around in chunks the size of a WORD will be the most efficient way. (On hardware or "system" level.)
With Java being more or less platform independant, it just defines a "WORD" as the next size from a "BYTE", meaning "full bandwidth". I guess any platform that's able to run Java will use 32 bits for a WORD.

My Postgres version is PostgreSQL 10.3 (Debian 10.3-1.pgdg90+1)
If you need to install an older version (for example 0.25):
pod _0.25.0_ install
Also in ubuntu, even though there was already SSH key entered in settings in BitBucket, I got this problem. The reason was, I was trying the following:
sudo git push origin master
Not sure why, but it got solved by using
git push origin master
No sudo used.

Use NGX Cookie Service
Inastall this package: npm install ngx-cookie-service --save
Add the cookie service to your app.module.ts as a provider:
import { CookieService } from 'ngx-cookie-service';
@NgModule({
declarations: [ AppComponent ],
imports: [ BrowserModule, ... ],
providers: [ CookieService ],
bootstrap: [ AppComponent ]
})
Then call in your component:
import { CookieService } from 'ngx-cookie-service';
constructor( private cookieService: CookieService ) { }
ngOnInit(): void {
this.cookieService.set( 'name', 'Test Cookie' ); // To Set Cookie
this.cookieValue = this.cookieService.get('name'); // To Get Cookie
}
That's it!
Try setting mapper.configure(DeserializationConfig.Feature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true)
or

depending on your Jackson version.
Actually the orderBy filter can take as a parameter not only a string but also a function. From the orderBy documentation: https://docs.angularjs.org/api/ng/filter/orderBy):
function: Getter function. The result of this function will be sorted using the <, =, > operator.
So, you could write your own function. For example, if you would like to compare cards based on a sum of opt1 and opt2 (I'm making this up, the point is that you can have any arbitrary function) you would write in your controller:
$scope.myValueFunction = function(card) {
return card.values.opt1 + card.values.opt2;
};
and then, in your template:
ng-repeat="card in cards | orderBy:myValueFunction"
The other thing worth noting is that orderBy is just one example of AngularJS filters so if you need a very specific ordering behaviour you could write your own filter (although orderBy should be enough for most uses cases).
Check out this link it has a example code to encrypt/decrypt data using AES256CBC using EVP API.
https://github.com/saju/misc/blob/master/misc/openssl_aes.c
Also you can check the use of AES256 CBC in a detailed open source project developed by me at https://github.com/llubu/mpro
The code is detailed enough with comments and if you still need much explanation about the API itself i suggest check out this book Network Security with OpenSSL by Viega/Messier/Chandra (google it you will easily find a pdf of this..) read chapter 6 which is specific to symmetric ciphers using EVP API.. This helped me a lot actually understanding the reasons behind using various functions and structures of EVP.
and if you want to dive deep into the Openssl crypto library, i suggest download the code from the openssl website (the version installed on your machine) and then look in the implementation of EVP and aeh api implementation.
One more suggestion from the code you posted above i see you are using the api from aes.h instead use EVP. Check out the reason for doing this here OpenSSL using EVP vs. algorithm API for symmetric crypto nicely explained by Daniel in one of the question asked by me..
Don't forget if you already have a DateTime object and are not sure if it's UTC or Local, it's easy enough to use the methods on the object directly:
DateTime convertedDate = DateTime.Parse(date);
DateTime localDate = convertedDate.ToLocalTime();
How do we adjust for the extra hour?
Unless specified .net will use the local pc settings. I'd have a read of: http://msdn.microsoft.com/en-us/library/system.globalization.daylighttime.aspx
By the looks the code might look something like:
DaylightTime daylight = TimeZone.CurrentTimeZone.GetDaylightChanges( year );
And as mentioned above double check what timezone setting your server is on. There are articles on the net for how to safely affect the changes in IIS.
I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).
I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.
[Desktop Entry]
Name=No name
Encoding=UTF-8
Version=1.0
Exec=vncconfig -nowin
X-GNOME-Autostart-enabled=true
Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.
Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.
The word "read" is vague, but here is an example which reads a jpeg file using the Image class, and prints information about it.
from PIL import Image
jpgfile = Image.open("picture.jpg")
print(jpgfile.bits, jpgfile.size, jpgfile.format)
Very simply, you can rename your Python script to "pythonscript.cgi". Post that in your cgi-bin directory, add the appropriate permissions and browse to it.
This is a great link you can start with.
Hope that helps.
EDIT (09/12/2015): The second link has long been removed. Replaced it with one that provides information referenced from the original.
Though you can use First(), Dictionaries do not have order per se. Please use OrderedDictionary instead. And then you can do FirstOrDefault. This way it will be meaningful.

Symfony 3.0Prior to Symfony 2.6 you would use SecurityContext.
SecurityContext will be deprecated in Symfony 3.0 in favour of the AuthorizationChecker.
For Symfony 2.6+ & Symfony 3.0 use AuthorizationChecker.
// Get our Security Context Object - [deprecated in 3.0]
$security_context = $this->get('security.context');
# e.g: $security_context->isGranted('ROLE_ADMIN');
// Get our Token (representing the currently logged in user)
$security_token = $security_context->getToken();
# e.g: $security_token->getUser();
# e.g: $security_token->isAuthenticated();
# [Careful] ^ "Anonymous users are technically authenticated"
// Get our user from that security_token
$user = $security_token->getUser();
# e.g: $user->getEmail(); $user->isSuperAdmin(); $user->hasRole();
// Check for Roles on the $security_context
$isRoleAdmin = $security_context->isGranted('ROLE_ADMIN');
# e.g: (bool) true/false
security.context becomes security.authorization_checker.
We now get our token from security.token_storage instead of the security.context
// [New 3.0] Get our "authorization_checker" Object
$auth_checker = $this->get('security.authorization_checker');
# e.g: $auth_checker->isGranted('ROLE_ADMIN');
// Get our Token (representing the currently logged in user)
// [New 3.0] Get the `token_storage` object (instead of calling upon `security.context`)
$token = $this->get('security.token_storage')->getToken();
# e.g: $token->getUser();
# e.g: $token->isAuthenticated();
# [Careful] ^ "Anonymous users are technically authenticated"
// Get our user from that token
$user = $token->getUser();
# e.g (w/ FOSUserBundle): $user->getEmail(); $user->isSuperAdmin(); $user->hasRole();
// [New 3.0] Check for Roles on the $auth_checker
$isRoleAdmin = $auth_checker->isGranted('ROLE_ADMIN');
// e.g: (bool) true/false

git read-tree -um @ $commit_to_revert_to
will do it. It's "git checkout" but without updating HEAD.
You can achieve the same effect with
git checkout $commit_to_revert_to
git reset --soft @{1}
if you prefer stringing convenience commands together.
These leave you with your worktree and index in the desired state, you can just git commit to finish.
For the first question I think answer would be:
<your DataFrame>.rename(columns={'count':'Total_Numbers'})
or
<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']
As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:
Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]
I was able to setup a SSL certificated for a domain AND multiple subdomains by using using --cert-name combined with --expand options.
See official certbot-auto documentation at https://certbot.eff.org/docs/using.html
Example:
certbot-auto certonly --cert-name mydomain.com.br \
--renew-by-default -a webroot -n --expand \
--webroot-path=/usr/share/nginx/html \
-d mydomain.com.br \
-d www.mydomain.com.br \
-d aaa1.com.br \
-d aaa2.com.br \
-d aaa3.com.br
It is likely that you're using a pager such as less or most since the output of ps aux is longer than a screenful. If so, the following options will cause (or force) long lines to wrap instead of being truncated.
ps aux | less -+S
ps aux | most -w
If you use either of the following commands, lines won't be wrapped but you can use your arrow keys or other movement keys to scroll left and right.
ps aux | less -S # use arrow keys, or Esc-( and Esc-), or Alt-( and Alt-)
ps aux | most # use arrow keys, or < and > (Tab can also be used to scroll right)
Lines are always wrapped for more and pg.
When ps aux is used in a pipe, the w option is unnecessary since ps only uses screen width when output is to the terminal.
Use this syntax for VB.NET 2005/2008 compatibility:
Dim theVar As New List(Of String)(New String() {"one", "two", "three"})
Although the VB.NET 2010 syntax is prettier.

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming
Update March 2013
Git 1.8.2 added the possibility to track branches.
"
git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".
Also see Vogella's tutorial on submodules for general information on submodules.
Note:
git submodule add -b . [URL to Git repo];
^^^
A special value of
.is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
See commit b928922727d6691a3bdc28160f93f25712c565f6:
submodule add: If --branch is given, record it in .gitmodulesThis allows you to easily record a
submodule.<name>.branchoption in.gitmoduleswhen you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):
A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.
So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:
gitslave (that you already looked at) seems to be the best fit, including for the commit operation.
It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).
Other alternatives are detailed here.
You can do it right in your XML file:
android:onClick="@drawable/ic_action_search"
If you need to set the mirror in a non-interactive way (for example doing an rbundler install in a deploy script) you can do it in this way:
First manually run:
chooseCRANmirror()
Pick the mirror number that is best for you and remember it. Then to automate the selection:
R -e 'chooseCRANmirror(graphics=FALSE, ind=87);library(rbundler);bundle()'
Where 87 is the number of the mirror you would like to use. This snippet also installs the rbundle for you. You can omit that if you like.
If you are using jruby instead of ruby you will have similar issues when installing the pg gem. Instead you need to install the adaptor:
gem 'activerecord-jdbcpostgresql-adapter'
I ended up going with a shell script that you should only really have to run once when you first checkout a project
#!/usr/bin/env bash

If I understand correctly, you want PowerShell to send the ENTER keystroke to some interactive application?
$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('title of the application window')
Sleep 1
$wshell.SendKeys('~')
If that interactive application is a PowerShell script, just use whatever is in the title bar of the PowerShell window as the argument to AppActivate (by default, the path to powershell.exe). To avoid ambiguity, you can have your script retitle its own window by using the title 'new window title' command.
A few notes:
{ENTER}, though they're not identical - that's the keypad's ENTER key. A complete list is available here: http://msdn.microsoft.com/en-us/library/office/aa202943%28v=office.10%29.aspx.Sleep 1 statement is to wait 1 second because it takes a moment for the window to activate, and if you invoke SendKeys immediately, it'll send the keys to the PowerShell window, or to nowhere.Sometimes wscript.shell's SendKeys method can be a little quirky, so if you run into problems, replace the fourth line above with this:
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SendKeys]::SendWait('~');
-eq is the shell comparison operator for comparing integers. For comparing strings you need to use =.
Disclaimer: This is silly
There is actually a way to add comments, and stay within the specification (no additional parser needed). It will not result into human-readable comments without any sort of parsing though.
You could abuse the following:
Insignificant whitespace is allowed before or after any token. Whitespace is any sequence of one or more of the following code points: character tabulation (U+0009), line feed (U+000A), carriage return (U+000D), and space (U+0020).
In a hacky way, you can abuse this to add a comment. For instance: start and end your comment with a tab. Encode the comment in base3 and use the other whitespace characters to represent them. For instance.
010212 010202 011000 011000 011010 001012 010122 010121 011021 010202 001012 011022 010212 011020 010202 010202
(hello base three in ASCII) But instead of 0 use space, for 1 use line feed and for 2 use carriage return.
This will just leave you with a lot of unreadable whitespace (unless you make an IDE plugin to encode/decode it on the fly).
I never even tried this, for obvious reasons and neither should you.
Here is an example of how to use strtok borrowed from MSDN.
And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).
char string[] = "A string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;
int main( void )
{
printf( "Tokens:\n" );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s\n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}
This is not an answer for the OP but I've seen a lot of people confused about how to avoid this error in the comments. This is a simple way to pass the compiler check
if (typeof(object) !== 'undefined') {
// your code
}
Note: This won't work
if (object !== undefined) {
// your code
}
You have two choices to get Toolbar in fragment
First one
Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.toolbar);
and second one
Toolbar toolbar = ((MainActivity) getActivity()).mToolbar;
For increasing execution time and file size, you need to mention below values in your .htaccess file. It will work.
php_value upload_max_filesize 80M
php_value post_max_size 80M
php_value max_input_time 18000
php_value max_execution_time 18000
OLD (pre v4):
Writing in es6 and using react 0.14.6 / react-router 2.0.0-rc5. I use this command to lookup the query params in my components:
this.props.location.query
It creates a hash of all available query params in the url.
UPDATE (React Router v4+):
this.props.location.query in React Router 4 has been removed (currently using v4.1.1) more about the issue here: https://github.com/ReactTraining/react-router/issues/4410
Looks like they want you to use your own method to parse the query params, currently using this library to fill the gap: https://github.com/sindresorhus/query-string
default is a keyword that is used as an access modifier for methods and variables.
Using this access modifier will make your class, variable, method or constructor acessible from own class or package, it will be also is set if no access modifier is present.
Access Levels
Modifier Class Package Subclass EveryWhere
public Y Y Y Y
protected Y Y Y N
default Y Y N N
private Y N N N
if you use a default in a interface you will be able to implement a method there like this exemple
public interface Computer {
default void Start() {
throw new UnsupportedOperationException("Error");
}
}
However it will only works from the 8 Java version
Add your <script> to the bottom of your <body>, or add an event listener for DOMContentLoaded following this StackOverflow question.
If that script executes in the <head> section of the code, document.getElementsByClassName(...) will return an empty array because the DOM is not loaded yet.
You're getting the Type Error because you're referencing search_span[0], but search_span[0] is undefined.
This works when you execute it in Dev Tools because the DOM is already loaded.
Tuple classes allow developers to be 'quick and lazy' by not defining a specific class for a specific use.
The property names are Item1, Item2, Item3 ..., which may not be meaningful in some cases or without documentation.
Tuple classes have strongly typed generic parameters. Still users of the Tuple classes may infer from the type of generic parameters.
The best simple approach :
error: function (xhr) {
var err = JSON.parse(xhr.responseText);
alert(err.message);
}
Modern browsers today seem to block (by default) these autoplay features. They are somewhat treated as pop-ops. Very intrusive. So yeah, users now have the complete control on when the sounds are played. [1,2,3]
<audio controls autoplay loop hidden>
<source src="audio.mp3" type="audio/mpeg">
</audio>
<embed src="audio.mp3" style="visibility:hidden" />
If xhr.abort(); causes page reload,
Then you can set onreadystatechange before abort to prevent:
// ? prevent page reload by abort()
xhr.onreadystatechange = null;
// ? may cause page reload
xhr.abort();
For a efficient solution, you can use .values() function to get a list of dict objects and then dump it to json response by using i.e. JsonResponse (remember to set safe=False).
Once you have your desired queryset object, transform it to JSON response like this:
...
data = list(queryset.values())
return JsonResponse(data, safe=False)
You can specify field names in .values() function in order to return only wanted fields (the example above will return all model fields in json objects).
Steps:
Example
x=pd.DataFrame([1,2,3,4])
def add(i1, i2):
return i1+i2
x.apply(add,i2=9)
The outcome of this example is that each number in the dataframe will be added to the number 9.
0
0 10
1 11
2 12
3 13
Explanation:
The "add" function has two parameters: i1, i2. The first parameter is going to be the value in data frame and the second is whatever we pass to the "apply" function. In this case, we are passing "9" to the apply function using the keyword argument "i2".
So when sending the message to telegram you use:
$token = <Enter Your Token Here>
$url = "https://api.telegram.org/bot".$token;
$chat_id = <The Chat Id Goes Here>;
$test = <Message goes Here>;
//sending Message normally without styling
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text");
If our message has html tags in it we add "parse_mode" so that our url becomes:
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text&parse_mode=html")
parse mode can be "HTML" or "markdown"
Old topic, but never clearly answered. I've been working on similar as well, and found the solution:
The pipe (|) in this code sample from Austin isn't the delimiter, but to pipe the ForEach-Object, so if you want to use it as delimiter, you need to do this:
Import-Csv H:\Programs\scripts\SomeText.csv -delimiter "|" |`
ForEach-Object {
$Name += $_.Name
$Phone += $_."Phone Number"
}
Spent a good 15 minutes on this myself before I understood what was going on. Hope the answer helps the next person reading this avoid the wasted minutes! (Sorry for expanding on your comment Austin)
Hook denotes a place in the code where you dispatch an event of certain type, and if this event was registered before with a proper function to call back, then it would be handled by this registered function, otherwise nothing happens.
Simple Use PHP function (imagescale):
Syntax:
imagescale ( $image , $new_width , $new_height )
Example:
Step: 1 Read the file
$image_name = 'path_of_Image/Name_of_Image.jpg|png';
Step: 2: Load the Image File
$image = imagecreatefromjpeg($image_name); // For JPEG
//or
$image = imagecreatefrompng($image_name); // For PNG
Step: 3: Our Life-saver comes in '_' | Scale the image
$imgResized = imagescale($image , 500, 400); // width=500 and height = 400
// $imgResized is our final product
Note: imagescale will work for (PHP 5 >= 5.5.0, PHP 7)

For a small enum like this, I find the most readable solution to be:
public enum Direction {
NORTH {
@Override
public Direction getOppositeDirection() {
return SOUTH;
}
},
SOUTH {
@Override
public Direction getOppositeDirection() {
return NORTH;
}
},
EAST {
@Override
public Direction getOppositeDirection() {
return WEST;
}
},
WEST {
@Override
public Direction getOppositeDirection() {
return EAST;
}
};
public abstract Direction getOppositeDirection();
}

If you imported a maven project into an IDE, then there is probably a maven setting in your IDE for default compiler that your maven runner is using.
[a-zA-Z] should do that just fine.
You can reference the cheat sheet.
The problem: You want to backup you image container WITH the data volumes in it but this option is Not out off the box, The straight forward and trivial way would be copy the volumes path and backup the docker image 'reload it and and link it both together. but this solution seems to be clumsy and not sustainable and maintainable - You would need to create a cron job that would make this flow each time.
Solution: Using dockup - Docker image to backup your Docker container volumes and upload it to s3 (Docker + Backup = dockup) . dockup will use your AWS credentials to create a new bucket with name as per the environment variable ,gets the configured volumes and will be tarballed, gzipped, time-stamped and uploaded to the S3 bucket.
Steps:
docker-compose.yml and attach the env.txt configuration file to it, The data should be uploaded to a dedicated secured s3 bucket and ready to be reloaded on DRP executions. in order to verify which volumes path to configure run docker inspect <service-name> and locate the volumes :"Volumes": { "/etc/service-example": {}, "/service-example": {} },
Edit the content of the configuration file env.txt, and place it on the project path:
AWS_ACCESS_KEY_ID=<key_here>
AWS_SECRET_ACCESS_KEY=<secret_here>
AWS_DEFAULT_REGION=us-east-1
BACKUP_NAME=service-backup
PATHS_TO_BACKUP=/etc/service-example /service-example
S3_BUCKET_NAME=docker-backups.example.com
RESTORE=false
Run the dockup container
$ docker run --rm \ --env-file env.txt \ --volumes-from <service-name> \ --name dockup tutum/dockup:latest
For php 7.1
sudo apt-get install php7.1-mbstring
Cheers!
You have to resolve the conflict manually (copying the file over) and then commit the file (no matter if you copied it over or used the local version) like this
git commit -a -m "Fix merge conflict in test.foo"
Git normally autocommits after merging, but when it detects conflicts it cannot solve by itself, it applies all patches it figured out and leaves the rest for you to resolve and commit manually. The Git Merge Man Page, the Git-SVN Crash Course or this blog entry might shed some light on how it's supposed to work.
Edit: See the post below, you don't actually have to copy the files yourself, but can use
git checkout --ours -- path/to/file.txt
git checkout --theirs -- path/to/file.txt
to select the version of the file you want. Copying / editing the file will only be necessary if you want a mix of both versions.
Please mark mipadis answer as the correct one.
Use the output annotation
@Directive({
selector: 'interval-dir',
})
class IntervalDir {
@Output() everySecond = new EventEmitter();
@Output('everyFiveSeconds') five5Secs = new EventEmitter();
constructor() {
setInterval(() => this.everySecond.emit("event"), 1000);
setInterval(() => this.five5Secs.emit("event"), 5000);
}
}
@Component({
selector: 'app',
template: `
<interval-dir (everySecond)="everySecond()" (everyFiveSeconds)="everyFiveSeconds()">
</interval-dir>
`,
directives: [IntervalDir]
})
class App {
everySecond() { console.log('second'); }
everyFiveSeconds() { console.log('five seconds'); }
}
bootstrap(App);
When there's no project, Code::Blocks only compiles and links the current file. That file, from your picture, is secrypt.cpp, which does not have a main function. In order to compile and link both source files, you'll need to do it manually or add them to the same project.
Contrary to what others are saying, using a Windows subsystem with main will still work, but there will be no console window.
Your other attempt, compiling and linking just trial.cpp, never links secrypt.cpp. This would normally result in an undefined reference to jRegister(), but you've declared the function inside main instead of calling it. Change main to:
int main()
{
jRegister();
return 0;
}
Perhaps the shortest possible ways to evaluate an expression into "10" without digits are:
+!+[] + [+[]] // "10"
-~[] + [+[]] // "10"
//========== Explanation ==========\\
+!+[] : +[] Converts to 0. !0 converts to true. +true converts to 1.
-~[] = -(-1) which is 1
[+[]] : +[] Converts to 0. [0] is an array with a single element 0.
Then JS evaluates the 1 + [0], thus Number + Array expression. Then the ECMA specification works: + operator converts both operands to a string by calling the toString()/valueOf() functions from the base Object prototype. It operates as an additive function if both operands of an expression are numbers only. The trick is that arrays easily convert their elements into a concatenated string representation.
Some examples:
1 + {} // "1[object Object]"
1 + [] // "1"
1 + new Date() // "1Wed Jun 19 2013 12:13:25 GMT+0400 (Caucasus Standard Time)"
There's a nice exception that two Objects addition results in NaN:
[] + [] // ""
[1] + [2] // "12"
{} + {} // NaN
{a:1} + {b:2} // NaN
[1, {}] + [2, {}] // "1,[object Object]2,[object Object]"
app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
var data = {
"fruit": {
"apple": req.params.fruitName,
"color": req.params.fruitColor
}
};
send.json(data);
});
If that doesn't work, try using console.log(req.params) to see what it is giving you.
The Java code given by Dommer above gives slightly incorrect results but the small errors add up if you are processing say a GPS track. Here is an implementation of the Haversine method in Java which also takes into account height differences between two points.
/**
* Calculate distance between two points in latitude and longitude taking
* into account height difference. If you are not interested in height
* difference pass 0.0. Uses Haversine method as its base.
*
* lat1, lon1 Start point lat2, lon2 End point el1 Start altitude in meters
* el2 End altitude in meters
* @returns Distance in Meters
*/
public static double distance(double lat1, double lat2, double lon1,
double lon2, double el1, double el2) {
final int R = 6371; // Radius of the earth
double latDistance = Math.toRadians(lat2 - lat1);
double lonDistance = Math.toRadians(lon2 - lon1);
double a = Math.sin(latDistance / 2) * Math.sin(latDistance / 2)
+ Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2))
* Math.sin(lonDistance / 2) * Math.sin(lonDistance / 2);
double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
double distance = R * c * 1000; // convert to meters
double height = el1 - el2;
distance = Math.pow(distance, 2) + Math.pow(height, 2);
return Math.sqrt(distance);
}
Here's how to check if the input contains a digit:
if (input.matches(".*\\d.*")) {
// there's a digit somewhere in the input string
}
Here I found a workaround to pass multiple generic objects (as json) from jquery to a WEB API using JObject, and then cast back to your required specific object type in api controller. This objects provides a concrete type specifically designed for working with JSON.
var combinedObj = {};
combinedObj["obj1"] = [your json object 1];
combinedObj["obj2"] = [your json object 2];
$http({
method: 'POST',
url: 'api/PostGenericObjects/',
data: JSON.stringify(combinedObj)
}).then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
alert("Saved Successfully !!!");
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
alert("Error : " + response.data.ExceptionMessage);
});
and then you can get this object in your controller
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
public [OBJECT] PostGenericObjects(object obj)
{
string[] str = GeneralMethods.UnWrapObjects(obj);
var item1 = JsonConvert.DeserializeObject<ObjectType1>(str[0]);
var item2 = JsonConvert.DeserializeObject<ObjectType2>(str[1]);
return *something*;
}
I have made a generic function to unwrap the complex object, so there is no limitation of number of objects while sending and unwrapping. We can even send more than two objects
public class GeneralMethods
{
public static string[] UnWrapObjects(object obj)
{
JObject o = JObject.Parse(obj.ToString());
string[] str = new string[o.Count];
for (int i = 0; i < o.Count; i++)
{
string var = "obj" + (i + 1).ToString();
str[i] = o[var].ToString();
}
return str;
}
}
I have posted the solution to my blog with a little more description with simpler code to integrate easily.
Pass multiple complex objects to Web API
I hope it would help someone. I would be interested to hear from the experts here regarding the pros and cons of using this methodology.
