Common shell scripts often have to find their "home" directory even if they are invoked as a symlink. The script thus have to find their "real" position from just $0.
cat `mvn`
on my system prints a script containing the following, which should be a good hint at what you need.
if [ -z "$M2_HOME" ] ; then
## resolve links - $0 may be a link to maven's home
PRG="$0"
# need this for relative symlinks
while [ -h "$PRG" ] ; do
ls=`ls -ld "$PRG"`
link=`expr "$ls" : '.*-> \(.*\)$'`
if expr "$link" : '/.*' > /dev/null; then
PRG="$link"
else
PRG="`dirname "$PRG"`/$link"
fi
done
saveddir=`pwd`
M2_HOME=`dirname "$PRG"`/..
# make it fully qualified
M2_HOME=`cd "$M2_HOME" && pwd`
Another way to look at it is to consider git rebase master
as:
Rebase the current branch on top of
master
Here , 'master
' is the upstream branch, and that explain why, during a rebase, ours
and theirs
are reversed.
This isn't quite what you're looking for, but I've found it useful in similar circumstances.
I recently added the following to my $HOME/.bashrc
(something similar should be possible with shells other than bash):
if [ -f $HOME/.add-screen-to-history ] ; then
history -s 'screen -dr'
fi
I keep a screen
session running on one particular machine, and I've had problems with ssh
connections to that machine being dropped, requiring me to re-run screen -dr
every time I reconnect.
With that addition, and after creating that (empty) file in my home directory, I automatically have the screen -dr
command in my history when my shell starts. After reconnecting, I can just type Control-P Enter and I'm back in my screen session -- or I can ignore it. It's flexible, but not quite automatic, and in your case it's easier than typing tmux list-sessions
.
You might want to make the history -s
command unconditional.
This does require updating your $HOME/.bashrc
on each of the target systems, which might or might not make it unsuitable for your purposes.
<textarea name="hide" style="display:none;"></textarea>
This sets the css display

[TL;DR? You can skip to the end for a code example.]
I actually prefer to use a different idiom, which is a little involved for using as a one off, but is nice if you have a more complex use case.
A bit of background first.
Properties are useful in that they allow us to handle both setting and getting values in a programmatic way but still allow attributes to be accessed as attributes. We can turn 'gets' into 'computations' (essentially) and we can turn 'sets' into 'events'. So let's say we have the following class, which I've coded with Java-like getters and setters.
class Example(object):
def __init__(self, x=None, y=None):
self.x = x
self.y = y
def getX(self):
return self.x or self.defaultX()
def getY(self):
return self.y or self.defaultY()
def setX(self, x):
self.x = x
def setY(self, y):
self.y = y
def defaultX(self):
return someDefaultComputationForX()
def defaultY(self):
return someDefaultComputationForY()
You may be wondering why I didn't call defaultX
and defaultY
in the object's __init__
method. The reason is that for our case I want to assume that the someDefaultComputation
methods return values that vary over time, say a timestamp, and whenever x
(or y
) is not set (where, for the purpose of this example, "not set" means "set to None") I want the value of x
's (or y
's) default computation.
So this is lame for a number of reasons describe above. I'll rewrite it using properties:
class Example(object):
def __init__(self, x=None, y=None):
self._x = x
self._y = y
@property
def x(self):
return self.x or self.defaultX()
@x.setter
def x(self, value):
self._x = value
@property
def y(self):
return self.y or self.defaultY()
@y.setter
def y(self, value):
self._y = value
# default{XY} as before.
What have we gained? We've gained the ability to refer to these attributes as attributes even though, behind the scenes, we end up running methods.
Of course the real power of properties is that we generally want these methods to do something in addition to just getting and setting values (otherwise there is no point in using properties). I did this in my getter example. We are basically running a function body to pick up a default whenever the value isn't set. This is a very common pattern.
But what are we losing, and what can't we do?
The main annoyance, in my view, is that if you define a getter (as we do here) you also have to define a setter.[1] That's extra noise that clutters the code.
Another annoyance is that we still have to initialize the x
and y
values in __init__
. (Well, of course we could add them using setattr()
but that is more extra code.)
Third, unlike in the Java-like example, getters cannot accept other parameters. Now I can hear you saying already, well, if it's taking parameters it's not a getter! In an official sense, that is true. But in a practical sense there is no reason we shouldn't be able to parameterize an named attribute -- like x
-- and set its value for some specific parameters.
It'd be nice if we could do something like:
e.x[a,b,c] = 10
e.x[d,e,f] = 20
for example. The closest we can get is to override the assignment to imply some special semantics:
e.x = [a,b,c,10]
e.x = [d,e,f,30]
and of course ensure that our setter knows how to extract the first three values as a key to a dictionary and set its value to a number or something.
But even if we did that we still couldn't support it with properties because there is no way to get the value because we can't pass parameters at all to the getter. So we've had to return everything, introducing an asymmetry.
The Java-style getter/setter does let us handle this, but we're back to needing getter/setters.
In my mind what we really want is something that capture the following requirements:
Users define just one method for a given attribute and can indicate there whether the attribute is read-only or read-write. Properties fail this test if the attribute writable.
There is no need for the user to define an extra variable underlying the function, so we don't need the __init__
or setattr
in the code. The variable just exists by the fact we've created this new-style attribute.
Any default code for the attribute executes in the method body itself.
We can set the attribute as an attribute and reference it as an attribute.
We can parameterize the attribute.
In terms of code, we want a way to write:
def x(self, *args):
return defaultX()
and be able to then do:
print e.x -> The default at time T0
e.x = 1
print e.x -> 1
e.x = None
print e.x -> The default at time T1
and so forth.
We also want a way to do this for the special case of a parameterizable attribute, but still allow the default assign case to work. You'll see how I tackled this below.
Now to the point (yay! the point!). The solution I came up for for this is as follows.
We create a new object to replace the notion of a property. The object is intended to store the value of a variable set to it, but also maintains a handle on code that knows how to calculate a default. Its job is to store the set value
or to run the method
if that value is not set.
Let's call it an UberProperty
.
class UberProperty(object):
def __init__(self, method):
self.method = method
self.value = None
self.isSet = False
def setValue(self, value):
self.value = value
self.isSet = True
def clearValue(self):
self.value = None
self.isSet = False
I assume method
here is a class method, value
is the value of the UberProperty
, and I have added isSet
because None
may be a real value and this allows us a clean way to declare there really is "no value". Another way is a sentinel of some sort.
This basically gives us an object that can do what we want, but how do we actually put it on our class? Well, properties use decorators; why can't we? Let's see how it might look (from here on I'm going to stick to using just a single 'attribute', x
).
class Example(object):
@uberProperty
def x(self):
return defaultX()
This doesn't actually work yet, of course. We have to implement uberProperty
and
make sure it handles both gets and sets.
Let's start with gets.
My first attempt was to simply create a new UberProperty object and return it:
def uberProperty(f):
return UberProperty(f)
I quickly discovered, of course, that this doens't work: Python never binds the callable to the object and I need the object in order to call the function. Even creating the decorator in the class doesn't work, as although now we have the class, we still don't have an object to work with.
So we're going to need to be able to do more here. We do know that a method need only be represented the one time, so let's go ahead and keep our decorator, but modify UberProperty
to only store the method
reference:
class UberProperty(object):
def __init__(self, method):
self.method = method
It is also not callable, so at the moment nothing is working.
How do we complete the picture? Well, what do we end up with when we create the example class using our new decorator:
class Example(object):
@uberProperty
def x(self):
return defaultX()
print Example.x <__main__.UberProperty object at 0x10e1fb8d0>
print Example().x <__main__.UberProperty object at 0x10e1fb8d0>
in both cases we get back the UberProperty
which of course is not a callable, so this isn't of much use.
What we need is some way to dynamically bind the UberProperty
instance created by the decorator after the class has been created to an object of the class before that object has been returned to that user for use. Um, yeah, that's an __init__
call, dude.
Let's write up what we want our find result to be first. We're binding an UberProperty
to an instance, so an obvious thing to return would be a BoundUberProperty. This is where we'll actually maintain state for the x
attribute.
class BoundUberProperty(object):
def __init__(self, obj, uberProperty):
self.obj = obj
self.uberProperty = uberProperty
self.isSet = False
def setValue(self, value):
self.value = value
self.isSet = True
def getValue(self):
return self.value if self.isSet else self.uberProperty.method(self.obj)
def clearValue(self):
del self.value
self.isSet = False
Now we the representation; how do get these on to an object? There are a few approaches, but the easiest one to explain just uses the __init__
method to do that mapping. By the time __init__
is called our decorators have run, so just need to look through the object's __dict__
and update any attributes where the value of the attribute is of type UberProperty
.
Now, uber-properties are cool and we'll probably want to use them a lot, so it makes sense to just create a base class that does this for all subclasses. I think you know what the base class is going to be called.
class UberObject(object):
def __init__(self):
for k in dir(self):
v = getattr(self, k)
if isinstance(v, UberProperty):
v = BoundUberProperty(self, v)
setattr(self, k, v)
We add this, change our example to inherit from UberObject
, and ...
e = Example()
print e.x -> <__main__.BoundUberProperty object at 0x104604c90>
After modifying x
to be:
@uberProperty
def x(self):
return *datetime.datetime.now()*
We can run a simple test:
print e.x.getValue()
print e.x.getValue()
e.x.setValue(datetime.date(2013, 5, 31))
print e.x.getValue()
e.x.clearValue()
print e.x.getValue()
And we get the output we wanted:
2013-05-31 00:05:13.985813
2013-05-31 00:05:13.986290
2013-05-31
2013-05-31 00:05:13.986310
(Gee, I'm working late.)
Note that I have used getValue
, setValue
, and clearValue
here. This is because I haven't yet linked in the means to have these automatically returned.
But I think this is a good place to stop for now, because I'm getting tired. You can also see that the core functionality we wanted is in place; the rest is window dressing. Important usability window dressing, but that can wait until I have a change to update the post.
I'll finish up the example in the next posting by addressing these things:
We need to make sure UberObject's __init__
is always called by subclasses.
We need to make sure we handle the common case where someone 'aliases' a function to something else, such as:
class Example(object):
@uberProperty
def x(self):
...
y = x
We need e.x
to return e.x.getValue()
by default.
e.x.getValue()
. (Doing this one is obvious, if you haven't already fixed it out.)We need to support setting e.x directly
, as in e.x = <newvalue>
. We can do this in the parent class too, but we'll need to update our __init__
code to handle it.
Finally, we'll add parameterized attributes. It should be pretty obvious how we'll do this, too.
Here's the code as it exists up to now:
import datetime
class UberObject(object):
def uberSetter(self, value):
print 'setting'
def uberGetter(self):
return self
def __init__(self):
for k in dir(self):
v = getattr(self, k)
if isinstance(v, UberProperty):
v = BoundUberProperty(self, v)
setattr(self, k, v)
class UberProperty(object):
def __init__(self, method):
self.method = method
class BoundUberProperty(object):
def __init__(self, obj, uberProperty):
self.obj = obj
self.uberProperty = uberProperty
self.isSet = False
def setValue(self, value):
self.value = value
self.isSet = True
def getValue(self):
return self.value if self.isSet else self.uberProperty.method(self.obj)
def clearValue(self):
del self.value
self.isSet = False
def uberProperty(f):
return UberProperty(f)
class Example(UberObject):
@uberProperty
def x(self):
return datetime.datetime.now()
[1] I may be behind on whether this is still the case.
Another option would be to use the jQuery Transit Framework to handle your CSS3 transitions. The transitions/effects perform well on mobile devices and you don't have to add a single line of messy CSS3 transitions in your CSS file in order to do the animation effects.
Here is an example that will transition an element's opacity to 0 when you click on it and will be removed once the transition is complete:
$("#element").click( function () {
$('#element').transition({ opacity: 0 }, function () { $(this).remove(); });
});
The best solution I have found is this:
function subtracMonth($currentMonth, $monthsToSubtract){
$finalMonth = $currentMonth;
for($i=0;$i<$monthsToSubtract;$i++) {
$finalMonth--;
if ($finalMonth=='0'){
$finalMonth = '12';
}
}
return $finalMonth;
}
So if we are in 3(March) and we want to subtract 5 months that would be
subtractMonth(3,5);
which would give 10(October). If the year is also desired, one could do this:
function subtracMonth($currentMonth, $monthsToSubtract){
$finalMonth = $currentMonth;
$totalYearsToSubtract = 0;
for($i=0;$i<$monthsToSubtract;$i++) {
$finalMonth--;
if ($finalMonth=='0'){
$finalMonth = '12';
$totalYearsToSubtract++;
}
}
//Get $currentYear
//Calculate $finalYear = $currentYear - $totalYearsToSubtract
//Put resulting $finalMonth and $finalYear into an object as attributes
//Return the object
}
Pre-increment means that the variable is incremented BEFORE it's evaluated in the expression. Post-increment means that the variable is incremented AFTER it has been evaluated for use in the expression.
Therefore, look carefully and you'll see that all three assignments are arithmetically equivalent.
I find it easy to make an image of a line, and then insert it into the code as a "rule", setting the width and/or height as needed. These have all been horizontal-rule images, but there's nothing stopping me (or you) from using a "vertical-rule" image.
This is cool for many reasons; you can use different lines, colors, or patterns easily as "rules", and since they would have no text, even if you had done it the "normal" way using hr in HTML, it shouldn't impact SEO or other stuff like that. And the image file would/should be very tiny (1 or 2KB at most).
Just in case someone has the same pb. :
I couldn't unmount the mount point (here /mnt
) of a chroot jail.
Here are the commands I typed to investigate :
$ umount /mnt
umount: /mnt: target is busy.
$ df -h | grep /mnt
/dev/mapper/VGTout-rootFS 4.8G 976M 3.6G 22% /mnt
$ fuser -vm /mnt/
USER PID ACCESS COMMAND
/mnt: root kernel mount /mnt
$ lsof +f -- /dev/mapper/VGTout-rootFS
$
As you can notice, even lsof
returns nothing.
Then I had the idea to type this :
$ df -ah | grep /mnt
/dev/mapper/VGTout-rootFS 4.8G 976M 3.6G 22% /mnt
dev 2.9G 0 2.9G 0% /mnt/dev
$ umount /mnt/dev
$ umount /mnt
$ df -ah | grep /mnt
$
Here it was a /mnt/dev
bind to /dev
that I had created to be able to repair my system inside from the chroot jail.
After umounting it, my pb. is now solved.

You should be able to do it using the X-UA meta tag:
<meta http-equiv="X-UA-Compatible" content="IE=9" />
However, if you find yourself having to do this, you're probably doing something wrong and should take a look at what you're doing and see if you can do it a different/better way.
On any other element, I would use the scrollHeight
of the DOM object and set the height accordingly. I don't know if this would work on an iframe (because they're a bit kooky about everything) but it's certainly worth a try.
Edit: Having had a look around, the popular consensus is setting the height from within the iframe using the offsetHeight
:
function setHeight() {
parent.document.getElementById('the-iframe-id').style.height = document['body'].offsetHeight + 'px';
}
And attach that to run with the iframe-body's onLoad
event.

Just like in this question (npm global path prefix) all you need is to set proper npm prefix
.
UNIX:
$ npm config set prefix /usr/local
$ npm install -g bower
$ which bower
>> /usr/local/bin/bower
Windows ans NVM:
$ npm config set prefix /c/Users/xxxxxxx/AppData/Roaming/nvm/v8.9.2
$ npm install -g bower
Then bower
should be located just in your $PATH
.
I had this problem and this is the best solution without any external or additional script libraries: In Javascript tags or file create this function: We assume here that canvas is your canvas:
function download(){
var download = document.getElementById("download");
var image = document.getElementById("canvas").toDataURL("image/png")
.replace("image/png", "image/octet-stream");
download.setAttribute("href", image);
}
In the body part of your HTML specify the button:
<a id="download" download="image.png"><button type="button" onClick="download()">Download</button></a>
This is working and download link looks like a button. Tested in Firefox and Chrome.
You can associate directly the function object window.destroy
to the command
attribute of your button
:
button = Button (frame, text="Good-bye.", command=window.destroy)
This way you will not need the function close_window
to close the window for you.

to combine other props
from this answer on 'react-router - pass props to handler component'N.B. With the render
method you have to pass through the props from the Route
component explicitly. You also want to use render
and not component
for performance reasons (component
forces a reload every time).
const App = (props) => (
<Route
path="/home"
render={routeProps => <MyComponent {...props} {...routeProps}>}
/>
)
const MyComponent = (props) => (
/**
* @link https://reacttraining.com/react-router/web/example/auth-workflow
* N.B. I use `props.history` instead of `history`
*/
<button onClick={() => {
fakeAuth.signout(() => props.history.push('/foo'))
}}>Sign out</button>
)
One of the confusing things I found is that in quite a few of the React Router v4 docs they use MyComponent = ({ match })
i.e. Object destructuring, which meant initially I didn't realise that Route
passes down three props, match
, location
and history
I think some of the other answers here are assuming that everything is done via JavaScript classes.
Here's an example, plus if you don't need to pass any props
through you can just use component
class App extends React.Component {
render () {
<Route
path="/home"
component={MyComponent}
/>
}
}
class MyComponent extends React.Component {
render () {
/**
* @link https://reacttraining.com/react-router/web/example/auth-workflow
* N.B. I use `props.history` instead of `history`
*/
<button onClick={() => {
this.fakeAuth.signout(() => this.props.history.push('/foo'))
}}>Sign out</button>
}
}
if you have null value then in doing mathematical operation you will get this error to resolve it use df[~df['x'].isnull()]df[['x']].astype(int)
if you want your dataset to be unchangeable.
Creating a table and copying the data in a single command:
create table T_NEW as
select * from T;
* This will not copy PKs, FKs, Triggers, etc.
It can be done using javascript. Say your html/aspx code goes this way:
<span>Main heading</span>
<asp:Label ID="lbl1" runat="server" Text="Contents"></asp:Label>
<asp:Label Text="Contractor Name" ID="lblCont" runat="server"></asp:Label>
<div id="forPrintPreview">
<asp:Label Text="Company Name" runat="server"></asp:Label>
<asp:GridView runat="server">
//GridView Content goes here
</asp:GridView
</div>
<input type="button" onclick="PrintPreview();" value="Print Preview" />
Here on click of "Print Preview" button we will open a window with data for print. Observe that 'forPrintPreview' is the id of a div. The function for Print preview goes this way:
function PrintPreview() {
var Contractor= $('span[id*="lblCont"]').html();
printWindow = window.open("", "", "location=1,status=1,scrollbars=1,width=650,height=600");
printWindow.document.write('<html><head>');
printWindow.document.write('<style type="text/css">@media print{.no-print, .no-print *{display: none !important;}</style>');
printWindow.document.write('</head><body>');
printWindow.document.write('<div style="width:100%;text-align:right">');
//Print and cancel button
printWindow.document.write('<input type="button" id="btnPrint" value="Print" class="no-print" style="width:100px" onclick="window.print()" />');
printWindow.document.write('<input type="button" id="btnCancel" value="Cancel" class="no-print" style="width:100px" onclick="window.close()" />');
printWindow.document.write('</div>');
//You can include any data this way.
printWindow.document.write('<table><tr><td>Contractor name:'+ Contractor +'</td></tr>you can include any info here</table');
printWindow.document.write(document.getElementById('forPrintPreview').innerHTML);
//here 'forPrintPreview' is the id of the 'div' in current page(aspx).
printWindow.document.write('</body></html>');
printWindow.document.close();
printWindow.focus();
}
Observe that buttons 'print' and 'cancel' has the css class 'no-print', So these buttons will not appear in the print.
I think you're confusing server code with client code.
JavaScript runs on the client after it has received data from the server (like a webpage).
PHP runs on the server before it sends the data.
So there are two ways with interacting with JavaScript with php.
Like above, you can generate javascript with php in the same fashion you generate HTML with php.
Or you can use an AJAX request from javascript to interact with the server. The server can respond with data and the javascript can receive that and do something with it.
I'd recommend going back to the basics and studying how HTTP works in the server-client relationship. Then study the concept of server side languages and client side languages.
Then take a tutorial with ajax, and you will start getting the concept.
Good luck, google is your friend.
What
Basically the difference between kernel and user modes is not OS dependent and is achieved only by restricting some instructions to be run only in kernel mode by means of hardware design. All other purposes like memory protection can be done only by that restriction.
How
It means that the processor lives in either the kernel mode or in the user mode. Using some mechanisms the architecture can guarantee that whenever it is switched to the kernel mode the OS code is fetched to be run.
Why
Having this hardware infrastructure these could be achieved in common OSes:
If you wanted to make your own (for semantic reasons or otherwise), see below for an example, though s///
should be all you need:
#!/usr/bin/perl -w
use strict;
main();
sub main{
my $foo = "blahblahblah";
print '$foo: ' , replace("lah","ar",$foo) , "\n"; #$foo: barbarbar
}
sub replace {
my ($from,$to,$string) = @_;
$string =~s/$from/$to/ig; #case-insensitive/global (all occurrences)
return $string;
}
You can use the command move
move <source directory> <destination directory>
Assuming that ID
is an identity column:
INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32
Try to avoid loops with SQL. Try to think in terms of sets instead.
like this?
DF <- data.frame("a" = as.character(0:5),
"b" = paste(0:5, ".1", sep = ""),
"c" = paste(10:15),
stringsAsFactors = FALSE)
DF <- apply(DF, 2, as.numeric)
If there are "real" characters in dataframe like 'a' 'b' 'c', i would recommend answer from davsjob.
Using two extension methods, this becomes very easy:
public static class Ext
{
public static void SetText(this RichTextBox richTextBox, string text)
{
richTextBox.Document.Blocks.Clear();
richTextBox.Document.Blocks.Add(new Paragraph(new Run(text)));
}
public static string GetText(this RichTextBox richTextBox)
{
return new TextRange(richTextBox.Document.ContentStart,
richTextBox.Document.ContentEnd).Text;
}
}
You CAN do it using only xml shapes - just use layer-list AND negative padding like this:
<layer-list>
<item>
<shape>
<solid android:color="#ffffff" />
<padding android:top="20dp" />
</shape>
</item>
<item>
<shape>
<gradient android:endColor="#ffffff" android:startColor="#efefef" android:type="linear" android:angle="90" />
<padding android:top="-20dp" />
</shape>
</item>
</layer-list>
Use an "Or"
Select SUM(CAmount) as PaymentAmount
from TableOrderPayment
where (CPaymentType='Check' Or CPaymentType='Cash')
and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
and CStatus='" & "Active" & "'"
or an "IN"
Select SUM(CAmount) as PaymentAmount
from TableOrderPayment
where CPaymentType IN ('Check', 'Cash')
and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
and CStatus='" & "Active" & "'"
Instead of adding onSubmit event, you can prevent the default action for submit button.
So, in the following html:
<form name="form" action="insert.php" method="post">
<input type='submit' />
</form>?
first, prevent submit button action. Then make the ajax call asynchronously, and submit the form when the password is correct.
$('input[type=submit]').click(function(e) {
e.preventDefault(); //prevent form submit when button is clicked
var password = $.trim($('#employee_password').val());
$.ajax({
type: "POST",
url: "checkpass.php",
data: "password="+password,
success: function(html) {
var arr=$.parseJSON(html);
var $form = $('form');
if(arr == "Successful")
{
$form.submit(); //submit the form if the password is correct
}
}
});
});????????????????????????????????
the name of the the test case for class Foo should be FooTestCase or something like it (FooIntegrationTestCase or FooAcceptanceTestCase) - since it is a test case. see http://xunitpatterns.com/ for some standard naming conventions like test, test case, test fixture, test method, etc.
I don't think desc
takes an na.rm
argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NA
s, use na.omit
(base) or tidyr::drop_na
:
outcome.df %>%
na.omit() %>%
group_by(Hospital, State) %>%
arrange(desc(HeartAttackDeath)) %>%
head()
library(tidyr)
outcome.df %>%
drop_na() %>%
group_by(Hospital, State) %>%
arrange(desc(HeartAttackDeath)) %>%
head()
If you only want to remove NA
s from the HeartAttackDeath column, filter with is.na
, or use tidyr::drop_na
:
outcome.df %>%
filter(!is.na(HeartAttackDeath)) %>%
group_by(Hospital, State) %>%
arrange(desc(HeartAttackDeath)) %>%
head()
outcome.df %>%
drop_na(HeartAttackDeath) %>%
group_by(Hospital, State) %>%
arrange(desc(HeartAttackDeath)) %>%
head()
As pointed out at the dupe, complete.cases
can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:
outcome.df %>%
filter(complete.cases(.)) %>%
group_by(Hospital, State) %>%
arrange(desc(HeartAttackDeath)) %>%
head()
If you want to use SQL Server Management Studio, you want to install the full Oracle client, not the Instant Client. The full Oracle client is on the same download page as the Oracle database. Assuming that you are installing on a 64-bit version of Windows, I expect you want the "Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64)" download. This is several hundred MB rather than a couple of MB for the Instant Client.
This will work
a:hover, a:focus, a:active {
outline: none;
}
What this does is removes the outline for all the three pseudo-classes.
It's best if you worked with DataSet
s and/or DataTable
s. Once you have that, ideally straight from your stored procedure with proper column names for headers, you can use the following method:
ws.Cells.LoadFromDataTable(<DATATABLE HERE>, true, OfficeOpenXml.Table.TableStyles.Light8);
.. which will produce a beautiful excelsheet with a nice table!
Now to serve your file, assuming you have an ExcelPackage
object as in your code above called pck
..
Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("Content-Disposition", "attachment;filename=" + sFilename);
Response.BinaryWrite(pck.GetAsByteArray());
Response.End();
Set
wins due to near instant 'contains' checks: https://en.wikipedia.org/wiki/Hash_table
List implementation: usually an array, low level close to the metal good for iteration and random access by element index.
Set implementation: https://en.wikipedia.org/wiki/Hash_table, it does not iterate on a list, but finds the element by computing a hash from the key, so it depends on the nature of the key elements and the hash function. Similar to what is used for dict. I suspect list
could be faster if you have very few elements (< 5), the larger element count the better the set
will perform for a contains check. It is also fast for element addition and removal. Also always keep in mind that building a set has a cost !
NOTE: If the list
is already sorted, searching the list
could be quite fast on small lists, but with more data a set
is faster for contains checks.
See this answer: there is in Ruby 1.9.2, but not in earlier versions. Personally I think rand(8) + 3 is fine, but if you're interested check out the Random class described in the link.
**Inside Model**

The database is a MySQL database, not a phpMyAdmin database. phpMyAdmin is only PHP code that connects to the DB.
mysql_connect('localhost', 'username', 'password') or die (mysql_error());
mysql_select_database('db_name') or die (mysql_error());

If your textbox is a Required field and have some regex pattern to match and has minlength and maxlength

Adding a column using SSMS or ALTER TABLE .. ADD
will not drop any existing data.
echo 5a | python -c "import sys; print chr(int(sys.stdin.read(),base=16))"
You can just go for String
replace method.-
line1 = line1.replace("\"", "");
You need to do the following:
private static Field getField(Class<?> cls, String fieldName) {
for (Class<?> c = cls; c != null; c = c.getSuperclass()) {
try {
final Field field = c.getDeclaredField(fieldName);
field.setAccessible(true);
return field;
} catch (final NoSuchFieldException e) {
// Try parent
} catch (Exception e) {
throw new IllegalArgumentException(
"Cannot access field " + cls.getName() + "." + fieldName, e);
}
}
throw new IllegalArgumentException(
"Cannot find field " + cls.getName() + "." + fieldName);
}
From all my searching around, I strongly say that the most practical, accurate and free data source is provided by GeoNames.
You can access their data in 2 ways:
String[] strarray = strlist.toArray(new String[0]);
if u want List convert to string use StringUtils.join(slist, '\n');
I just encounter the same error. I was able to figure out the root cause by enabling the log_statement and log_min_error_statement in my local PostgreSQL.

If the rectangles overlap then the overlap area will be greater than zero. Now let us find the overlap area:
If they overlap then the left edge of overlap-rect will be the max(r1.x1, r2.x1)
and right edge will be min(r1.x2, r2.x2)
. So the length of the overlap will be min(r1.x2, r2.x2) - max(r1.x1, r2.x1)
So the area will be:
area = (max(r1.x1, r2.x1) - min(r1.x2, r2.x2)) * (max(r1.y1, r2.y1) - min(r1.y2, r2.y2))
If area = 0
then they don't overlap.
Simple isn't it?
From ?matrix
: "A matrix is the special case of a two-dimensional 'array'." You can simply change the dimensions of the matrix/array.
Elts_int <- as.matrix(tmp_int) # read.table returns a data.frame as Brandon noted
dim(Elts_int) <- (maxrow_int*maxcol_int,1)
I've implemented facebook-like slideout navigation in this library project.
You can easy built it into your application, your UI and navigation. You will need to implement only one Activity and one Fragment, let library know about it - and library will provide all wanted animations and navigation.
Inside the repo you can find demo-project, with how to use the lib to implement facebook-like navigation. Here is short video with record of demo project.
Also this lib should be compatible this ActionBar pattern, because is based on Activities transactions and TranslateAnimations (not Fragments transactions and custom Views).
Right now, the most problem is to make it work well for application, which support both portrait and landscape mode. If you have any feedback, please provide it via github.
All the best,

In PyObjC, you can do the equivalent of #pragma mark
for the symbols dropdown:
#MARK: Foo
and
#MARK: -
Apple have changed the name of the certificate that is issued. You can now use the same certificate for both development and production. While you can still request a development only certificate you can no longer request a production only certificate.
Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:
If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php
Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an
iframe
embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.
The best solution I created is to simply use google as the ssl proxy...
https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky
Tested and works in firefox.
Other Methods:
Use a Third party such as embed.ly (but it it really only good for well known http APIs).
Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)
https://example.com
That has a iframe linking to...
https://example.com/utilities/redirect.html
Which has a simple js redirect script like...
document.location.href ="http://thenonsslsite.com";
Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.
You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.
Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).
The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.
Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.
Update the bind-address = 0.0.0.0
in the /etc/mysql/mysql.conf.d/mysqld.cnf
and from the mysql command line allow the root

Below was the only commands worked for mysql-8.0 as other were failing with error syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'abcd'' at line 1
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
UPDATE mysql.user SET host='%' WHERE user='root';
Restart the mysql client
sudo service mysql restart
If you want to stage and commit all your files on Github do the following;

The answer by Chinmay Kanchi is excellent but I wanted an example of a function which passes and returns a variables/arrays to a C++ code. I though I'd include it here in case it is useful to others.
Passing and returning an integer
The C++ code for a function which takes an integer and adds one to the returned value,
extern "C" int add_one(int i)
{
return i+1;
}
Saved as file test.cpp
, note the required extern "C" (this can be removed for C code).
This is compiled using g++, with arguments similar to Chinmay Kanchi answer,
g++ -shared -o testlib.so -fPIC test.cpp
The Python code uses load_library
from the numpy.ctypeslib
assuming the path to the shared library in the same directory as the Python script,
import numpy.ctypeslib as ctl
import ctypes
libname = 'testlib.so'
libdir = './'
lib=ctl.load_library(libname, libdir)
py_add_one = lib.add_one
py_add_one.argtypes = [ctypes.c_int]
value = 5
results = py_add_one(value)
print(results)
This prints 6 as expected.
Passing and printing an array
You can also pass arrays as follows, for a C code to print the element of an array,
extern "C" void print_array(double* array, int N)
{
for (int i=0; i<N; i++)
cout << i << " " << array[i] << endl;
}
which is compiled as before and the imported in the same way. The extra Python code to use this function would then be,
import numpy as np
py_print_array = lib.print_array
py_print_array.argtypes = [ctl.ndpointer(np.float64,
flags='aligned, c_contiguous'),
ctypes.c_int]
A = np.array([1.4,2.6,3.0], dtype=np.float64)
py_print_array(A, 3)
where we specify the array, the first argument to print_array
, as a pointer to a Numpy array of aligned, c_contiguous 64 bit floats and the second argument as an integer which tells the C code the number of elements in the Numpy array. This then printed by the C code as follows,
1.4
2.6
3.0
You can install your iOS app without iTunes, App store, or third party sites.
When you build the archive in xcode you can select for adhoc distribution. xcode will bring you through a dialogue where you enter the URL location where your app will be along with the urls for a 57x57 pixel png and a 512x512 pixel png. It will create a bundle with your ipa and manifest.plist
Upload your ipa and the two png files whereever you plan to host them. It has to have an SSL certificate and be served over https. You may want to upload your manifest.plist there as well, but technically I'm pretty sure you can have it somewhere else.
Next, somewhere, in a text, or a webpage or email, or whereever share your link as:
<a href="itms-services://?action=download-manifest&url=https://URL/path/manifest.plist">Download anchor text</a>

I have many times succeeded to get div's without line breaks after them, by playing around with the float css attribute and the width css attribute.
Of course after working out the solution you have to test it in all browsers, and in each browser you have to re-size the windows to make sure that it works in all circumstances.

Just connect to Internet and start Android Studio and open your project. While Gradle Sync it will download the dependencies from Internet(All JAR Files). This solved it for me. No Editing in Gradle file ,all was done by Android Studio Automatically. Using Android Studio 2.2 :)
Also don't forget to install Java JDK 1.x(7 or 8 all works fine).
They are format specifiers. They are used when you want to include the value of your Python expressions into strings, with a specific format enforced.

A bit late to the game but if I'm understanding your needs correctly this will help people with the same issue.
Two solutions with the same first step: First navigate to the location you keep your scripts in and copy the filepath to that directory.
First Solution:
You can now use any of your scripts as if you were already that folder.
Second Solution: (can easily be paired with the first for extra usefulness)
On your desktop create a batch file with the following content.

$mail->SMTPAuth = true;
$mail->Username = 'Email Address';
$mail->Password = 'Email Account Password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

Use the :not
pseudo-class to exclude the classes you don't want the hover to apply to:
<div class="test"> blah </div>
<div class="test"> blah </div>
<div class="test nohover"> blah </div>
.test:not(.nohover):hover {
border: 1px solid red;
}
This does what you want in one css rule!
If your Object represents a number, eg, such as an Integer, you can cast it to a Number then call the doubleValue() method.
Double asDouble(Object o) {
Double val = null;
if (o instanceof Number) {
val = ((Number) o).doubleValue();
}
return val;
}
I found this post through the fact that I had this error myself in my own code and I know that it has been a while since this was posted and you already got some answers and fixed issue for that situation but just wanted to explain how I fixed it just in case it could help someone else!! Basically what I thought at first was that the code editor as was using REPL.it as was making something for a friend and knew that she wouldn't want to have to download like a code editor anyways the point is I thought that it couldn't handle the code because the complexity was at 139 at that point got even higher afterwards, but then I began experimenting and realized that within my set of functions just outside of a true loop within my a_loop function for that letter to register it needed to define it! So basically I wasn't defining the Value in this case a counting feature actually within the code! I would share my code here but it's kind of personal as in the print statements and also it's 2349 lines long and yeah anyway hope this helps! Also recommend using if you can in my case for some of the code I could, putting it into way more scripts if you can to make it easier on your brain! Once again hope this helps, if you have any questions, please feel free to ask and I will answer to the best of my ability! I hope this helps!!!

Just another method....
In the debugger you don't need to add back slashes, the input field understands the special chars.
In java code you need to escape the special chars
If you are using Windows/Visual Studio and need to convert a string to wstring you could use:
#include <AtlBase.h>
#include <atlconv.h>
...
string s = "some string";
CA2W ca2w(s.c_str());
wstring w = ca2w;
printf("%s = %ls", s.c_str(), w.c_str());
Same procedure for converting a wstring to string (sometimes you will need to specify a codepage):
#include <AtlBase.h>
#include <atlconv.h>
...
wstring w = L"some wstring";
CW2A cw2a(w.c_str());
string s = cw2a;
printf("%s = %ls", s.c_str(), w.c_str());
You could specify a codepage and even UTF8 (that's pretty nice when working with JNI/Java). A standard way of converting a std::wstring to utf8 std::string is showed in this answer.
//
// using ATL
CA2W ca2w(str, CP_UTF8);
//
// or the standard way taken from the answer above
#include <codecvt>

If you want to know more about codepages there is an interesting article on Joel on Software: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets.
These CA2W (Convert Ansi to Wide=unicode) macros are part of ATL and MFC String Conversion Macros, samples included.
Sometimes you will need to disable the security warning #4995', I don't know of other workaround (to me it happen when I compiled for WindowsXp in VS2012).
#pragma warning(push)
#pragma warning(disable: 4995)
#include <AtlBase.h>
#include <atlconv.h>
#pragma warning(pop)
Edit: Well, according to this article the article by Joel appears to be: "while entertaining, it is pretty light on actual technical details". Article: What Every Programmer Absolutely, Positively Needs To Know About Encoding And Character Sets To Work With Text.
use this
android:background="@drawable/ic_play_arrow_black_24dp"
just set the background to the icon you want to center
Something like this could probably do the trick:
<?php
$words = implode(' ', array_slice(split($input, ' ', 21), 0, 20));
If you're using Linux, there's a possibility of a conflict with Alt + click, which is the default for "moving a window".
You can go to menu Settings → Window Behavior → Window Behavior → Actions tab
Just remove Alt + left (hold) and it will work.
This is the best way, because you don't need to hold two + keys to do such a simple task.
The best way to do this is by running the command:
git diff --name-only --cached
When you check the manual you will likely find the following:
--name-only
Show only names of changed files.
And on the example part of the manual:
git diff --cached
Changes between the index and your current HEAD.
Combined together you get the changes between the index and your current HEAD
and Show only names of changed files.
Update: --staged
is also available as an alias for --cached
above in more recent git versions.

I think you should not rely on the implicit conversion. It is a bad practice.
Instead you should try like this:
datenum >= to_date('11/26/2013','mm/dd/yyyy')
or like
datenum >= date '2013-09-01'
Check out the manual: http://www.php.net/manual/en/datetime.format.php
<?php
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:s');
?>
Will output: 2000-01-01 00:00:00
You need to add a name
attribute.
Since this is a multiple select, at the HTTP level, the client just sends multiple name/value pairs with the same name, you can observe this yourself if you use a form with method="GET": someurl?something=1&something=2&something=3
.
In the case of PHP, Ruby, and some other library/frameworks out there, you would need to add square braces ([]
) at the end of the name. The frameworks will parse that string and wil present it in some easy to use format, like an array.
Apart from manually parsing the request there's no language/framework/library-agnostic way of accessing multiple values, because they all have different APIs
For PHP you can use:
<select name="something[]" id="inscompSelected" multiple="multiple" class="lstSelected">
The preferred way to specify toolchain-specific options is using CMake's toolchain facility. This ensures that there is a clean division between:
Ideally, there should be no compiler/linker flags in your CMakeLists.txt files -- even within if
/endif
blocks. And your program should build for the native platform with the default toolchain (e.g. GCC on GNU/Linux or MSVC on Windows) without any additional flags.
Steps to add a toolchain:
Create a file, e.g. arm-linux-androideadi-gcc.cmake with global toolchain settings:
set(CMAKE_CXX_COMPILER arm-linux-gnueabihf-g++)
set(CMAKE_CXX_FLAGS_INIT "-fexceptions")
(You can find an example Linux cross-compiling toolchain file here.)
When you want to generate a build system with this toolchain, specify the CMAKE_TOOLCHAIN_FILE
parameter on the command line:
mkdir android-arm-build && cd android-arm-build
cmake -DCMAKE_TOOLCHAIN_FILE=$(pwd)/../arm-linux-androideadi-gcc.cmake ..
(Note: you cannot use a relative path.)
Build as normal:
cmake --build .
Toolchain files make cross-compilation easier, but they have other uses:
Hardened diagnostics for your unit tests.
set(CMAKE_CXX_FLAGS_INIT "-Werror -Wall -Wextra -Wpedantic")
Tricky-to-configure development tools.
# toolchain file for use with gcov
set(CMAKE_CXX_FLAGS_INIT "--coverage -fno-exceptions -g")
Enhanced safety checks.
# toolchain file for use with gdb
set(CMAKE_CXX_FLAGS_DEBUG_INIT "-fsanitize=address,undefined -fsanitize-undefined-trap-on-error")
set(CMAKE_EXE_LINKER_FLAGS_INIT "-fsanitize=address,undefined -static-libasan")
Since you are iterating over an indexable collection (lists, etc.), I presume that you can then just iterate with the indices of the elements:
IntStream.range(0, params.size())
.forEach(idx ->
query.bind(
idx,
params.get(idx)
)
)
;
The resulting code is similar to iterating a list with the classic i++-style for loop, except with easier parallelizability (assuming, of course, that concurrent read-only access to params is safe).
Note that if you are closing each line with ;
, the SET IDENTITY_INSERT mytable ON
command will not hold for the following lines.
i.e.
a query like
SET IDENTITY_INSERT mytable ON;
INSERT INTO mytable (VoucherID, name) VALUES (1, 'Cole');
Gives the error
Cannot insert explicit value for identity column in table 'mytable' when IDENTITY_INSERT is set to OFF.
But a query like this will work:
SET IDENTITY_INSERT mytable ON
INSERT INTO mytable (VoucherID, name) VALUES (1, 'Cole')
SET IDENTITY_INSERT mytable OFF;
It seems like the SET IDENTITY_INSERT
command only holds for a transaction, and the ;
will signify the end of a transaction.
Seems that the commands:
docker build -t imagename .
and:
docker build -t imagename - < Dockerfile2
are not executed the same way. If you want to build 2 docker images from within one folder with Dockerfile and Dockerfile2, the COPY command cannot be used in the second example using stdin (< Dockerfile2). Instead you have to use:
docker build -t imagename -f Dockerfile2 .
Then COPY does work as expected.
Try this one. It works for me.

Just in case if someone stumbles onto this thread then here is a bullet proof solution to SQL Server stuck in SINGLE USER MODE
-- Get the process ID (spid) of the connection you need to kill
-- Replace 'DBName' with the actual name of the DB
SELECT sd.[name], sp.spid, sp.login_time, sp.loginame
FROM sysprocesses sp
INNER JOIN sysdatabases sd on sp.dbid = sd.dbid
WHERE sd.[name] = 'DBName'
As an alternative, you can also use the command “sp_who” to get the “spid” of the open connection:
-- Or use this SP instead
exec sp_who
-- Then Execute the following and replace the [spid] and [DBName] with correct values
KILL SpidToKillGoesHere
GO
SET DEADLOCK_PRIORITY HIGH
GO
ALTER DATABASE [DBName] SET MULTI_USER WITH ROLLBACK IMMEDIATE
GO
The Observable object represents a push based collection.
The Observer and Observable interfaces provide a generalized mechanism for push-based notification, also known as the observer design pattern. The Observable object represents the object that sends notifications (the provider); the Observer object represents the class that receives them (the observer).
The Subject class inherits both Observable and Observer, in the sense that it is both an observer and an observable. You can use a subject to subscribe all the observers, and then subscribe the subject to a backend data source
var subject = new Rx.Subject();
var subscription = subject.subscribe(
function (x) { console.log('onNext: ' + x); },
function (e) { console.log('onError: ' + e.message); },
function () { console.log('onCompleted'); });
subject.onNext(1);
// => onNext: 1
subject.onNext(2);
// => onNext: 2
subject.onCompleted();
// => onCompleted
subscription.dispose();

Try this
var Regex='/^[^a-zA-Z]*$/';

Starting with the observation that we can retrieve the ids of a table (eg. count 5) based on a set:
select *
from table_name
where _id in (4, 1, 2, 5, 3)
we can come to the result that if we could generate the string "(4, 1, 2, 5, 3)"
, then we would have a more efficient way than RAND()
.
For example, in Java:
ArrayList<Integer> indices = new ArrayList<Integer>(rowsCount);
for (int i = 0; i < rowsCount; i++) {
indices.add(i);
}
Collections.shuffle(indices);
String inClause = indices.toString().replace('[', '(').replace(']', ')');
If ids have gaps, then the initial arraylist indices
is the result of an sql query on ids.
If you're looking for a minimal solution that invalidates the cache, this edited version of Dr Manhattan's solution should be sufficient. Note that I'm specifying the root / directory to indicate I want the whole site refreshed.

Have a look at the jai (-> mirror) (javascript audio interface) site. From looking at their source, they appear to be calling play()
repeatedly, and they mention that their library might be appropriate for use in HTML5-based games.
You can fire multiple audio events simultaneously, which could be used for creating Javascript games, or having a voice speaking over some background music
You can use pandas.cut
:
bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
percentage binned
0 46.50 (25, 50]
1 44.20 (25, 50]
2 100.00 (50, 100]
3 42.12 (25, 50]
bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
percentage binned
0 46.50 5
1 44.20 5
2 100.00 6
3 42.12 5
bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
percentage binned
0 46.50 5
1 44.20 5
2 100.00 6
3 42.12 5
...and then value_counts
or groupby
and aggregate size
:
s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50] 3
(50, 100] 1
(10, 25] 0
(5, 10] 0
(1, 5] 0
(0, 1] 0
Name: percentage, dtype: int64
s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1] 0

I don't think you need ui-router at all for this. The documentation available for the $location service says in the first paragraph, "...changes to $location are reflected into the browser address bar." It continues on later to say, "What does it not do? It does not cause a full page reload when the browser URL is changed."
So, with that in mind, why not simply change the $location.path (as the method is both a getter and setter) with something like the following:
var newPath = IdFromService;
$location.path(newPath);
The documentation notes that the path should always begin with a forward slash, but this will add it if it's missing.
The only thing I can add to Stephan202's answer is a recommendation that you take a look at David Beazley's PyCon '08 presentation "Generator Tricks for Systems Programmers," which is the best single explanation of the how and why of generators that I've seen anywhere. This is the thing that took me from "Python looks kind of fun" to "This is what I've been looking for." It's at http://www.dabeaz.com/generators/.
x.transpose[6][3..8]
or x[3..8].map {|r| r [6]}
would give what you want.
Example:
a = [ [1, 2, 3, 4, 5],
[6, 7, 8, 9, 10],
[11, 12, 13, 14, 15],
[21, 22, 23, 24, 25]
]
#a[1..2][2] -> [8,13]
puts a.transpose[2][1..2].inspect # [8,13]
puts a[1..2].map {|r| r[2]}.inspect # [8,13]
To expand on others' answers, here is a compact solution that doesn't expose/add any new variables. It doesn't cover all bases, but it should suit most people who just want a single page app to remain functional (despite no data persistence after reload).
(function(){
try {
localStorage.setItem('_storage_test', 'test');
localStorage.removeItem('_storage_test');
} catch (exc){
var tmp_storage = {};
var p = '__unique__'; // Prefix all keys to avoid matching built-ins
Storage.prototype.setItem = function(k, v){
tmp_storage[p + k] = v;
};
Storage.prototype.getItem = function(k){
return tmp_storage[p + k] === undefined ? null : tmp_storage[p + k];
};
Storage.prototype.removeItem = function(k){
delete tmp_storage[p + k];
};
Storage.prototype.clear = function(){
tmp_storage = {};
};
}
})();
Another thing to keep in mind is that the string itself might be null.
public static Nullable<T> ToNullable<T>(this string s) where T: struct
{
Nullable<T> result = new Nullable<T>();
try
{
if (!string.IsNullOrEmpty(s) && s.Trim().Length > 0)
{
TypeConverter conv = TypeDescriptor.GetConverter(typeof(T));
result = (T)conv.ConvertFrom(s);
}
}
catch { }
return result;
}

The first step is to run the emulator
emulator -avd < avd_name>
then use adb to install the .apk
adb install < path to .apk file>
If adb throws error like APK already exists or something alike. Run the adb shell while emulator is running
adb shell
cd data/app
adb uninstall < apk file without using .apk>
If adb and emulator are commands not found do following
export PATH=$PATH://android-sdk-macosx/platform-tools://android-sdk-macosx/android-sdk-macosx/tools:
For future use put the above line at the end of .bash_profile

So, there is no difference between MySQL "database" and MySQL "schema": these are two names for the same thing - a namespace for tables and other DB objects.
For people with Oracle background: MySQL "database" a.k.a. MySQL "schema" corresponds to Oracle schema. The difference between MySQL and Oracle CREATE SCHEMA commands is that in Oracle the CREATE SCHEMA command does not actually create a schema but rather populates it with tables and views. And Oracle's CREATE DATABASE command does a very different thing than its MySQL counterpart.
It is hardware problem at all.
If you have nView, turn off Desktop Manager. In case of ATI, turn off HydraVision.

If you are clearing the cluster so that you can start again, then, in addition to what @rib47 said, I also do the following to ensure my systems are in a state ready for kubeadm init
again:
kubeadm reset -f
rm -rf /etc/cni /etc/kubernetes /var/lib/dockershim /var/lib/etcd /var/lib/kubelet /var/run/kubernetes ~/.kube/*
iptables -F && iptables -X
iptables -t nat -F && iptables -t nat -X
iptables -t raw -F && iptables -t raw -X
iptables -t mangle -F && iptables -t mangle -X
systemctl restart docker
You then need to re-install docker.io
, kubeadm
, kubectl
, and kubelet
to make sure they are at the latest versions for your distribution before you re-initialize the cluster.
EDIT: Discovered that calico adds firewall rules to the raw
table so that needs clearing out as well.
For those looking a concise answer,
If an assembly is compiled as a class library and provides types for other assemblies to use, then it has the ifle extension .dll
(dynamic link library), and it cannot be executed standalone.
Likewise, if an assembly is compiled as an application, then it has the file extension .exe
(executable) and can be executed standalone. Before .NET Core 3.0, console apps were compiled to .dll fles and had to be executed by the dotnet run command or a host executable. - Source
Keep the Screen On
First way:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
Second way:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:keepScreenOn="true">
...
</RelativeLayout>
Keep the CPU On:
<uses-permission android:name="android.permission.WAKE_LOCK" />
and
PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakelockTag");
wakeLock.acquire();
To release the wake lock, call wakelock.release()
. This releases your claim to the CPU. It's important to release a wake lock as soon as your app is finished using it to avoid draining the battery.

- Can someone give a simple definition of what
Record
is?
A Record<K, T>
is an object type whose property keys are K
and whose property values are T
. That is, keyof Record<K, T>
is equivalent to K
, and Record<K, T>[K]
is (basically) equivalent to T
.
- Is
Record<K,T>
merely a way of saying "all properties on this object will have typeT
"? Probably not all objects, sinceK
has some purpose...
As you note, K
has a purpose... to limit the property keys to particular values. If you want to accept all possible string-valued keys, you could do something like Record<string, T>
, but the idiomatic way of doing that is to use an index signature like { [k: string]: T }
.
- Does the
K
generic forbid additional keys on the object that are notK
, or does it allow them and just indicate that their properties are not transformed toT
?
It doesn't exactly "forbid" additional keys: after all, a value is generally allowed to have properties not explicitly mentioned in its type... but it wouldn't recognize that such properties exist:
declare const x: Record<"a", string>;
x.b; // error, Property 'b' does not exist on type 'Record<"a", string>'
and it would treat them as excess properties which are sometimes rejected:
declare function acceptR(x: Record<"a", string>): void;
acceptR({a: "hey", b: "you"}); // error, Object literal may only specify known properties
and sometimes accepted:
const y = {a: "hey", b: "you"};
acceptR(y); // okay
With the given example:
type ThreeStringProps = Record<'prop1' | 'prop2' | 'prop3', string>
Is it exactly the same as this?:
type ThreeStringProps = {prop1: string, prop2: string, prop3: string}
Yes!
Hope that helps. Good luck!
Use find. Seriously, it is the best way because then you can really see what files it's operating on:
find . -name "*.sql" -exec grep -H "slow" {} \;
Note, the -H is mac-specific, it shows the filename in the results.
You can see marked answer on top. But i used getDialog().getCurrentFocus()
and working well. I post this answer cause i cant type "this"
in my oncreatedialog.
So this is my answer. If you tried marked answer and not worked , you can simply try this:
InputMethodManager inputManager = (InputMethodManager) getActivity().getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(getDialog().getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
As answered by others, you will probably be happy with Apache Dbcp or c3p0. Both are popular, and work fine.
Regarding your doubt
Doesn't javax.sql or java.sql have pooled connection implementations? Why wouldn't it be best to use these?
They don't provide implementations, rather interfaces and some support classes, only revelant to the programmers that implement third party libraries (pools or drivers). Normally you don't even look at that. Your code should deal with the connections from your pool just as they were "plain" connections, in a transparent way.
This error occurs in angular when you didn't intialise the array blank.
For an example:
userlist: any[ ];
this.userlist = [ ];
or
userlist: any = [ ];
1) Check if you are using OnItemClickListener or OnClickListener (which is not supported for ListView)
Documentation Android Developers ListView
2) Check if you added Listener to your ListView properly. It's hooked on ListView not on ListAdapter!
ListView.setOnItemClickListener(listener);
3) If you need to use OnClickListener, check if you do use DialogInterface.OnClickListener
or View.OnClickListener
(they can be easily exchanged if not validated or if using both of them)
with the intl extension in PHP 5.3+, you can use the NumberFormatter class:
$amount = '12345.67';
$formatter = new NumberFormatter('en_GB', NumberFormatter::CURRENCY);
echo 'UK: ', $formatter->formatCurrency($amount, 'EUR'), PHP_EOL;
$formatter = new NumberFormatter('de_DE', NumberFormatter::CURRENCY);
echo 'DE: ', $formatter->formatCurrency($amount, 'EUR'), PHP_EOL;
which prints :
UK: €12,345.67
DE: 12.345,67 €
Your problem is that, if the user clicks cancel, operationType
is null and thus throws a NullPointerException. I would suggest that you move
if (operationType.equalsIgnoreCase("Q"))
to the beginning of the group of if statements, and then change it to
if(operationType==null||operationType.equalsIgnoreCase("Q")).
This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.
Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.
When you have Eclipse for Android developement installed:
import os
print os.path.basename(__file__)
this will give us the filename only. i.e. if abspath of file is c:\abcd\abc.py then 2nd line will print abc.py

Use %in%
as follows
A$C %in% B$C
Which will tell you which values of column C of A are in B.
What is returned is a logical vector. In the specific case of your example, you get:
A$C %in% B$C
# [1] TRUE FALSE TRUE TRUE
Which you can use as an index to the rows of A
or as an index to A$C
to get the actual values:
# as a row index
A[A$C %in% B$C, ] # note the comma to indicate we are indexing rows
# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4 # returns all values of A$C that are in B$C
We can negate it too:
A$C[!A$C %in% B$C]
[1] 2 # returns all values of A$C that are NOT in B$C
2 %in% B$C # "is the value 2 in B$C ?"
# FALSE
A$C[2] %in% B$C # "is the 2nd element of A$C in B$C ?"
# FALSE

For the record only, to add to Spudley's answer, there is also the possibility to use position: absolute
and margins if you know the column widths.
For me, the main issue when chossing a method is whether you need the columns to fill the whole height (equal heights), where table-cell is the easiest method (if you don't care much for older browsers).
Use the formatting pattern 'dd-MM-yyyy HH:mm:ss aa' to get date as 21-10-2020 20:53:42 pm
There are three types of variables:
The default values for instance and static variables are the same and depends on the type:
An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.
Once the array is created all of its elements are assiged with the default type value. For example:
private boolean[] list; // default value is null
private Boolean[] list; // default value is null
once is initialized:
private boolean[] list = new boolean[10]; // all ten elements are assigned to false
private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)
To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
If you care for it to be in the same order as before you can use a common table expression for that:
;WITH CTE AS (
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
)
SELECT *
FROM CTE
ORDER BY MySortColumn

I came across another elegant solution for this:
Place your printable part inside a div with an id like this:
<div id="printableArea">
<h1>Print me</h1>
</div>
<input type="button" onclick="printDiv('printableArea')" value="print a div!" />
Now let's create a really simple javascript:
function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
}

In your AsyncTask
add one ProgressDialog like:
private final ProgressDialog dialog = new ProgressDialog(YourActivity.this);
you can setMessage in onPreExecute()
method like:
this.dialog.setMessage("Processing...");
this.dialog.show();
and in your onPostExecute(Void result)
method dismiss your ProgressDialog
.
I know this is a very old post but as I was searching for additional solutions to this same error while running my command (I'd previously encountered the spaces in the Excel wb headers and remedied it with VBA each time the file is updated so I knew it wasn't that). I considered the fact that the xlsm file and DB were on separate network drives but didn't want to explore moving one unless it was my last resort.
I attempted to run the save import manually and there it was right in front of my face. The folder containing the xlsm file had been renamed....I changed the name back to match my saved import and....smh, it was that all along.
The answer from @Emiliano is excellent. You can also pass named parameters like so:
powershell.exe -Command 'G:\Karan\PowerShell_Scripts\START_DEV.ps1' -NamedParam1 "SomeDataA" -NamedParam2 "SomeData2"
Note the parameters are outside the command call, and you'll use:
[parameter(Mandatory=$false)]
[string]$NamedParam1,
[parameter(Mandatory=$false)]
[string]$NamedParam2
July 2015 - I have concluded that IntelliJ does not support automatically resolving imports with a single function. "Organize imports" simply removes unused imports, it does not resolve unimported types. Control-Space resolves a single unimported type. There does not exist a single action to resolve all types' imports.
For Java (not php, not javascript, not anyother):
txt.replaceAll("\\p{javaSpaceChar}{2,}"," ")
=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )
Explanation:
(MONTH($A$2:$A$6)=1)
creates an array of 1 and 0, it's 1 when the
month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]
SUMPRODUCT
first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6)
, then it sums them. Hence in
your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)
This works also in OpenOffice and Google Spreadsheets
You can do something like this:
<form action="../" onsubmit="return checkCheckBoxes(this);">
<p><input type="CHECKBOX" name="MyCheckbox" value="This..."> This...</p>
<p><input type="SUBMIT" value="Submit!"></p>
</form>
<script type="text/javascript" language="JavaScript">
<!--
function checkCheckBoxes(theForm) {
if (
theForm.MyCheckbox.checked == false)
{
alert ('You didn\'t choose any of the checkboxes!');
return false;
} else {
return true;
}
}
//-->
</script>
http://lab.artlung.com/validate-checkbox/
Although less legible imho, this can be done without a separate function definition like this:
<form action="../" onsubmit="if (this.MyCheckbox.checked == false) { alert ('You didn\'t choose any of the checkboxes!'); return false; } else { return true; }">
<p><input type="CHECKBOX" name="MyCheckbox" value="This..."> This...</p>
<p><input type="SUBMIT" value="Submit!"></p>
</form>
Expanding on comments by mbargiel and mycelo on the accepted answer, the following can be used with a non-blocking socket on the server end to inform whether the client has shut down.
This approach does not suffer the race condition that affects the Poll method in the accepted answer.
// Determines whether the remote end has called Shutdown
public bool HasRemoteEndShutDown
{
get
{
try
{
int bytesRead = socket.Receive(new byte[1], SocketFlags.Peek);
if (bytesRead == 0)
return true;
}
catch
{
// For a non-blocking socket, a SocketException with
// code 10035 (WSAEWOULDBLOCK) indicates no data available.
}
return false;
}
}
The approach is based on the fact that the Socket.Receive
method returns zero immediately after the remote end shuts down its socket and we've read all of the data from it. From Socket.Receive documentation:
If the remote host shuts down the Socket connection with the Shutdown method, and all available data has been received, the Receive method will complete immediately and return zero bytes.
If you are in non-blocking mode, and there is no data available in the protocol stack buffer, the Receive method will complete immediately and throw a SocketException.
The second point explains the need for the try-catch.
Use of the SocketFlags.Peek
flag leaves any received data untouched for a separate receive mechanism to read.
The above will work with a blocking socket as well, but be aware that the code will block on the Receive call (until data is received or the receive timeout elapses, again resulting in a SocketException
).
You can use this code it works fine.

I would say that you should only expect users to have a monitor with 800x600 resolution. The Canadian government has standards that list this as one of the requirements. Although that may seem low to somebody with a fancy widescreen monitor, remember that not everybody has a nice monitor. I still know a lot of people running at 1024x768. And it's not at all uncommon to run into someone who's running in 800x600, especially in cheap web cafes while travelling. Also, it's nice to have to make your browser window full screen if you don't want to. You can make the site wider on wider monitors, but don't make the user scroll horizontally. Ever. Another advantage of supporting lower resolutions is that your site will work on mobile phones and Nintendo Wii's a lot easier.
A note on your at least 1280 wide, I would have to say that's way overboard. Most 17 and even my 19 inch non widescreen monitors only support a maximum resolution of 1280x1024. And the 14 inch widescreen laptop I'm typing on right now is only 1280 pixels across. I would say that the largest minimum resolution you should strive for is 1024x768, but 800x600 would be ideal.
You can also use :checked
for <select>
elements
e.g.,
document.querySelector('select option:checked')
document.querySelector('select option:checked').getAttribute('value')
You don't even have to get the index and then reference the element by its sibling index.
They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).
The main equations are:
frame.origin = center - bounds.size / 2
(which is the same as)
center = frame.origin + bounds.size / 2
(and there’s also)
frame.size = bounds.size
That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.
This stuff is all explained in more detail with a useful mini-library here:
This is my answer
#include<stdio.h>
int main()
{int mat[100][100];
int row,column,i,j;
printf("enter how many row and colmn you want:\n \n");
scanf("%d",&row);
scanf("%d",&column);
printf("enter the matrix:");
for(i=0;i<row;i++){
for(j=0;j<column;j++){
scanf("%d",&mat[i][j]);
}
printf("\n");
}
for(i=0;i<row;i++){
for(j=0;j<column;j++){
printf("%d \t",mat[i][j]);}
printf("\n");}
}
I just choose an approximate value for the row and column. My selected row or column will not cross the value.and then I scan the matrix element then make it in matrix size.
If you need one single regex, try:
(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)
A short explanation:
(?=.*[a-z]) // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z]) // use positive look ahead to see if at least one upper case letter exists
(?=.*\d) // use positive look ahead to see if at least one digit exists
(?=.*\W]) // use positive look ahead to see if at least one non-word character exists
And I agree with SilentGhost, \W
might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?]
(feel free to add more of course!)
Use a JSON parser, like JSON.NET
string json = "{ \"Atlantic/Canary\": \"GMT Standard Time\", \"Europe/Lisbon\": \"GMT Standard Time\", \"Antarctica/Mawson\": \"West Asia Standard Time\", \"Etc/GMT+3\": \"SA Eastern Standard Time\", \"Etc/GMT+2\": \"UTC-02\", \"Etc/GMT+1\": \"Cape Verde Standard Time\", \"Etc/GMT+7\": \"US Mountain Standard Time\", \"Etc/GMT+6\": \"Central America Standard Time\", \"Etc/GMT+5\": \"SA Pacific Standard Time\", \"Etc/GMT+4\": \"SA Western Standard Time\", \"Pacific/Wallis\": \"UTC+12\", \"Europe/Skopje\": \"Central European Standard Time\", \"America/Coral_Harbour\": \"SA Pacific Standard Time\", \"Asia/Dhaka\": \"Bangladesh Standard Time\", \"America/St_Lucia\": \"SA Western Standard Time\", \"Asia/Kashgar\": \"China Standard Time\", \"America/Phoenix\": \"US Mountain Standard Time\", \"Asia/Kuwait\": \"Arab Standard Time\" }";
var data = (JObject)JsonConvert.DeserializeObject(json);
string timeZone = data["Atlantic/Canary"].Value<string>();
If you don't want to use the Task class (for instance, in .NET 3.5) you can just start all your threads, and then add them to the list and join them in a foreach loop.
Example:
List<Thread> threads = new List<Thread>();
// Start threads
for(int i = 0; i<10; i++)
{
int tmp = i; // Copy value for closure
Thread t = new Thread(() => Console.WriteLine(tmp));
t.Start;
threads.Add(t);
}
// Await threads
foreach(Thread thread in threads)
{
thread.Join();
}
here's one trick that I use to run My Nant Build script consecutively without having to click the batch file over and over again.
:CODELINE
NANT.EXE -buildfile:alltargets.build -l:build.log build.product
@pause
GOTO :CODELINE
What will happen is that after your solution finished building, it will be paused. And then if you press any key it will rerun the build script again. Very handy I must say.
Best way to replace linebreaks safely is
yourString.Replace("\r\n","\n") //handling windows linebreaks
.Replace("\r","\n") //handling mac linebreaks
that should produce a string with only \n (eg linefeed) as linebreaks. this code is usefull to fix mixed linebreaks too.

It's top google stackoverflow question, but all answers are not jQuery related!
$(".someclass").click(
function(event)
{
console.log(event, this);
}
);
'event' contains 2 important values:
event.currentTarget - element to which event is triggered ('.someclass' element)
event.target - element clicked (in case when inside '.someclass' [div] are other elements and you clicked on of them)
this - is set to triggered element ('.someclass'), but it's JavaScript element, not jQuery element, so if you want to use some jQuery function on it, you must first change it to jQuery element: $(this)
When your refresh the page and reload the scripts again; this method not work. You have to use jquery "unbind" method.
This is my JavaScript implementation of Algorithm P (Polar method for normal deviates) from Section 3.4.1 of Donald Knuth's book The Art of Computer Programming:
function normal_random(mean,stddev)
{
var V1
var V2
var S
do{
var U1 = Math.random() // return uniform distributed in [0,1[
var U2 = Math.random()
V1 = 2*U1-1
V2 = 2*U2-1
S = V1*V1+V2*V2
}while(S >= 1)
if(S===0) return 0
return mean+stddev*(V1*Math.sqrt(-2*Math.log(S)/S))
}
You can avoid any focus on your elements by setting the attribute android:descendantFocusability of the parent element.
Here is an example:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/search__scroller"
android:descendantFocusability="blocksDescendants"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
</ScrollView>
Here, the attribute android:descendantFocusability set to "blocksDescendants" is blocking the focus on the child elements.
You can find more info here.

The OP wanted to get the checked RadioButton BY GROUP. While @SLaks' answer is excellent, it doesn't really answer the OP's main question. To improve on @SLaks' answer, just take the LINQ one step further.
Here's an example from my own working code. Per normal WPF, my RadioButtons are contained in a Grid
(named "myGrid") with a bunch of other types of controls. I have two different RadioButton groups in the Grid.
To get the checked RadioButton from a particular group:
List<RadioButton> radioButtons = myGrid.Children.OfType<RadioButton>().ToList();
RadioButton rbTarget = radioButtons
.Where(r => r.GroupName == "GroupName" && r.IsChecked)
.Single();
If your code has the possibility of no RadioButtons being checked, then use SingleOrDefault()
(If I'm not using tri-state buttons, then I always set one button "IsChecked" as a default selection.)
I would rather use Last()
from LINQ to do it.
rows = rows.Remove(rows.Last());
or
rows = rows.Remove(rows.LastOrDefault());
It's not Twitter bootstrap specific, it is a normal HTML5 component and you can specify the range with the min
and max
attributes (in your case only the first attribute). For example:
<div> _x000D_
<input type="number" id="replyNumber" min="0" data-bind="value:replyNumber" />_x000D_
</div>
_x000D_
I'm not sure if only integers are allowed by default in the control or not, but else you can specify the step
attribute:
<div> _x000D_
<input type="number" id="replyNumber" min="0" step="1" data-bind="value:replyNumber" />_x000D_
</div>
_x000D_
Now only numbers higher (and equal to) zero can be used and there is a step of 1, which means the values are 0, 1, 2, 3, 4, ... .
BE AWARE: Not all browsers support the HTML5 features, so it's recommended to have some kind of JavaScript fallback (and in your back-end too) if you really want to use the constraints.
For a list of browsers that support it, you can look at caniuse.com.
You can use a single config file, and include the UglifyJS plugin conditionally using an environment variable:
const webpack = require('webpack');
const TerserPlugin = require('terser-webpack-plugin');
const PROD = JSON.parse(process.env.PROD_ENV || '0');
module.exports = {
entry: './entry.js',
devtool: 'source-map',
output: {
path: './dist',
filename: PROD ? 'bundle.min.js' : 'bundle.js'
},
optimization: {
minimize: PROD,
minimizer: [
new TerserPlugin({ parallel: true })
]
};
and then just set this variable when you want to minify it:
$ PROD_ENV=1 webpack
Edit:
As mentioned in the comments, NODE_ENV
is generally used (by convention) to state whether a particular environment is a production or a development environment. To check it, you can also set const PROD = (process.env.NODE_ENV === 'production')
, and continue normally.
Here is another alternative using Guava
List<Object> lst ...
List<String> ls = Lists.transform(lst, Functions.toStringFunction());
Hiding an <option>
element is not in the spec. But you can disable
them, which should work cross-browser.
$('option.hide').prop('disabled', true);
In my case, the problem was JS-CSS-HTML Formatter extension installed after january update. The default indent_char

To get around the problem, find out where pymysql is installed.
If for example it is installed in /usr/lib/python3.7/site-packages
, add the following code above the import pymysql
command:
import sys
sys.path.insert(0,"/usr/lib/python3.7/site-packages")
import pymysql
This ensures that your Python program can find where pymysql is installed.

Try the following, not sure which will work for all browsers or the browser you are working with, but it would be best to try all:
<textarea style="overflow:auto"></textarea>
Or
<textarea style="overflow:hidden"></textarea>
...As suggested above
You can also try adding this, I never used it before, just saw it posted on a site today:
<textarea style="resize:none"></textarea>
This last option would remove the ability to resize the textarea
. You can find more information on the CSS resize
property here
I had this issue until I removed the project in question from the server's deployments (in JBoss Dev Studio, right-click the server and "Remove" the project in the Servers view), then did the following:
After this, just restart the server (in debug or run mode) by selecting the server, NOT the project itself.
This seemed to flush any previous settings/states/memory/whatever that was causing the issue, and I no longer got the error.
You can use get methods:
var fullDate = new Date();_x000D_
console.log(fullDate);_x000D_
var twoDigitMonth = fullDate.getMonth() + "";_x000D_
if (twoDigitMonth.length == 1)_x000D_
twoDigitMonth = "0" + twoDigitMonth;_x000D_
var twoDigitDate = fullDate.getDate() + "";_x000D_
if (twoDigitDate.length == 1)_x000D_
twoDigitDate = "0" + twoDigitDate;_x000D_
var currentDate = twoDigitDate + "/" + twoDigitMonth + "/" + fullDate.getFullYear(); console.log(currentDate);
_x000D_
After doing some research, this was happening in Ruby's XMLRPC::Client
library - which uses NET::HTTP
. The client uses the start()
method in NET::HTTP
which keeps the connection open for future requests.
This happened precisely at 30 seconds after the last requests - so my assumption here is that the server it's hitting is closing requests after that time. I'm not sure what the default is for NET::HTTP
to keep the request open - but I'm about to test with 60 seconds to see if that solves the issue.
Using the android.support.v7.widget.AppCompatButton in the XML layout will allow you to avoid having to have a layout-21 or programmatically changing anything. Naturally this will also work with AppCompat v7 library.
<android.support.v7.widget.AppCompatButton
android:id="@+id/btnOpenMainDemo"
android:textAllCaps="false"
style="@style/HGButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/btn_main_demo"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"/>
Hope this helps.
Remove the width:100%;
declarations.
Block elements should take up the whole available width by default.
