Or you can use:
echo "1: " | awk '/1/{print $1-":"}'
This is a really funny equation.

You have it, that's all. But so, basically, what's the point of unions?
You can put in the same location content of different types. You have to know the type of what you have stored in the union (so often you put it in a struct
with a type tag...).
Why is this important? Not really for space gains. Yes, you can gain some bits or do some padding, but that's not the main point anymore.
It's for type safety, it enables you to do some kind of 'dynamic typing': the compiler knows that your content may have different meanings and the precise meaning of how your interpret it is up to you at run-time. If you have a pointer that can point to different types, you MUST use a union, otherwise you code may be incorrect due to aliasing problems (the compiler says to itself "oh, only this pointer can point to this type, so I can optimize out those accesses...", and bad things can happen).
When you have a certificate with both CN and Subject Alternative Names (SAN), if you make your request based on the CN content, then that particular content must also be present under SAN, otherwise it will fail with the error in question.
In my case CN had something, SAN had something else. I had to use SAN URL, and then it worked just fine.

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.
Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.
Possibly every remotely modern compiler implements #pragma pack
which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)
From C99 §6.7.2.1:
12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.
13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.
both are the same, but array_push makes a loop in it's parameter which is an array and perform $array[]=$element

In golang's wiki it show some tricks for slice, including delete an element from slice.
Link: enter link description here
For example a is the slice which you want to delete the number i element.
a = append(a[:i], a[i+1:]...)
OR
a = a[:i+copy(a[i:], a[i+1:])]
In my case I only wanted the image to behave responsively at mobile scale so I created a css style .myimgrsfix that only kicks in at mobile scale

}
}
and applied that to the image <img class='img-responsive myimgrsfix' src='whatever.gif'>

For more complex JSON parsing I suggest using python jsonpath module (by Stefan Goessner) -
sudo easy_install -U jsonpath
Example file.json (from http://goessner.net/articles/JsonPath) -
{ "store": {
"book": [
{ "category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{ "category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{ "category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{ "category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
}
}
Parse it (extract all book titles with price < 10) -
$ cat file.json | python -c "import sys, json, jsonpath; print '\n'.join(jsonpath.jsonpath(json.load(sys.stdin), 'store.book[?(@.price < 10)].title'))"
Will output -
Sayings of the Century

NOTE: The above command line does not include error checking. for full solution with error checking you should create small python script, and wrap the code with try-except.
I solved it.
I used destroy instead close function (it doesn't make any sense), but it worked.
$(document).ready(function() {
$('#showTerms').click(function()
{
$('#terms').css('display','inline');
$('#terms').dialog({resizable: false,
modal: true,
width: 400,
height: 450,
overlay: { backgroundColor: "#000", opacity: 0.5 },
buttons:{ "Close": function() { $(this).dialog('**destroy**'); } },
close: function(ev, ui) { $(this).close(); },
});
});
$('#form1 input#calendarTEST').datepicker({ dateFormat: 'MM d, yy' });
});
Yes, it is very Simple. Just Put your Code Inside this:
<androidx.core.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
//YOUR CODE
</androidx.core.widget.NestedScrollView>
From the jQuery.each() documentation:
.each( function(index, Element) )
function(index, Element)A function to execute for each matched element.
So you'll want to use:
$('#list option').each(function(i,e){
//do stuff
});
...where index will be the index and element will be the option element in list
Ternary operator should do nicely here: condition ? first_expression : second_expression;

DialogFragment is basically a Fragment that can be used as a dialog.
Using DialogFragment over Dialog due to the following reasons:
- DialogFragment is automatically re-created after configuration changes and save & restore flow
- DialogFragment inherits full Fragment’s lifecycle
- No more IllegalStateExceptions and leaked window crashes. This was pretty common when the activity was destroyed with the Alert Dialog still there.
To scale an image, you need to create a new image and draw into it. One way is to use the filter()
method of an AffineTransferOp
, as suggested here. This allows you to choose the interpolation technique.
private static BufferedImage scale1(BufferedImage before, double scale) {
int w = before.getWidth();
int h = before.getHeight();
// Create a new image of the proper size
int w2 = (int) (w * scale);
int h2 = (int) (h * scale);
BufferedImage after = new BufferedImage(w2, h2, BufferedImage.TYPE_INT_ARGB);
AffineTransform scaleInstance = AffineTransform.getScaleInstance(scale, scale);
AffineTransformOp scaleOp
= new AffineTransformOp(scaleInstance, AffineTransformOp.TYPE_BILINEAR);
scaleOp.filter(before, after);
return after;
}
Another way is to simply draw the original image into the new image, using a scaling operation to do the scaling. This method is very similar, but it also illustrates how you can draw anything you want in the final image. (I put in a blank line where the two methods start to differ.)
private static BufferedImage scale2(BufferedImage before, double scale) {
int w = before.getWidth();
int h = before.getHeight();
// Create a new image of the proper size
int w2 = (int) (w * scale);
int h2 = (int) (h * scale);
BufferedImage after = new BufferedImage(w2, h2, BufferedImage.TYPE_INT_ARGB);
AffineTransform scaleInstance = AffineTransform.getScaleInstance(scale, scale);
AffineTransformOp scaleOp
= new AffineTransformOp(scaleInstance, AffineTransformOp.TYPE_BILINEAR);
Graphics2D g2 = (Graphics2D) after.getGraphics();
// Here, you may draw anything you want into the new image, but we're
// drawing a scaled version of the original image.
g2.drawImage(before, scaleOp, 0, 0);
g2.dispose();
return after;
}
Addendum: Results
To illustrate the differences, I compared the results of the five methods below. Here is what the results look like, scaled both up and down, along with performance data. (Performance varies from one run to the next, so take these numbers only as rough guidelines.) The top image is the original. I scale it double-size and half-size.
As you can see, AffineTransformOp.filter()
, used in scaleBilinear()
, is faster than the standard drawing method of Graphics2D.drawImage()
in scale2()
. Also BiCubic interpolation is the slowest, but gives the best results when expanding the image. (For performance, it should only be compared with scaleBilinear()
and scaleNearest().
) Bilinear seems to be better for shrinking the image, although it's a tough call. And NearestNeighbor is the fastest, with the worst results. Bilinear seems to be the best compromise between speed and quality. The Image.getScaledInstance()
, called in the questionable()
method, performed very poorly, and returned the same low quality as NearestNeighbor. (Performance numbers are only given for expanding the image.)
public static BufferedImage scaleBilinear(BufferedImage before, double scale) {
final int interpolation = AffineTransformOp.TYPE_BILINEAR;
return scale(before, scale, interpolation);
}
public static BufferedImage scaleBicubic(BufferedImage before, double scale) {
final int interpolation = AffineTransformOp.TYPE_BICUBIC;
return scale(before, scale, interpolation);
}
public static BufferedImage scaleNearest(BufferedImage before, double scale) {
final int interpolation = AffineTransformOp.TYPE_NEAREST_NEIGHBOR;
return scale(before, scale, interpolation);

It is not mentioned which environment is used for executing Liquibase. In case it is Spring Boot 2 it is possible to extend liquibase.lockservice.StandardLockService
without the need to run direct SQL statements which is much cleaner. E.g.:
/**
* This class is enforcing to release the lock from the database.
*
*/
public class ForceReleaseLockService extends StandardLockService {
@Override
public int getPriority() {
return super.getPriority()+1;
}
@Override
public void waitForLock() throws LockException {
try {
super.forceReleaseLock();
} catch (DatabaseException e) {
throw new LockException("Could not enforce getting the lock.", e);
}
super.waitForLock();
}
}
The code is enforcing the release of the lock. This can be useful in test set-ups where the release call might not get called in case of errors or when the debugging is aborted.
The class must be placed in the liquibase.ext
package and will be picked up by the Spring Boot 2 auto configuration.
There is no easy way to remove the "outdated" stuff from an existing workspace. Using the "clean" parameter will not really help, as many of the files you refer to are "free form data", only known to the plugins that are no longer available.
Your best bet is to optimize the re-import, where I would like to point out the following:
${old_workspace}/.metadata/.plugins/org.eclipse.core.runtime/.settings
folder from the old to the new workspace. This is surely the fastest way, but it may lead to weird behaviour, because some of your plugins may depend on these settings and on some of the mentioned "free form data" stored elsewhere. (There are even people symlinking these folders over multiple workspaces, but this really requires to use the same plugins on all workspaces.)Angular5 and 6:
angular 5 and 6 recommended way is to use @HostBindings and @HostListeners instead of the host property
remove host and add @HostListener
@HostListener('ngModelChange', ['$event'])
onModelChange(event) {
this.onInputChange(event, false);
}
@HostListener('keydown.backspace', ['$event'])
keydownBackspace(event) {
this.onInputChange(event.target.value, true);
}

One way you could do it is using a directive that injects NgControl
and manipulates the value
(for details see inline comments)
@Directive({
selector: '[ngModel][phone]',
host: {
'(ngModelChange)': 'onInputChange($event)',
'(keydown.backspace)': 'onInputChange($event.target.value, true)'
}
})
export class PhoneMask {
constructor(public model: NgControl) {}
onInputChange(event, backspace) {
// remove all mask characters (keep only numeric)
var newVal = event.replace(/\D/g, '');
// special handling of backspace necessary otherwise
// deleting of non-numeric characters is not recognized
// this laves room for improvement for example if you delete in the
// middle of the string
if (backspace) {
newVal = newVal.substring(0, newVal.length - 1);
}
// don't show braces for empty value
if (newVal.length == 0) {
newVal = '';
}
// don't show braces for empty groups at the end
else if (newVal.length <= 3) {
newVal = newVal.replace(/^(\d{0,3})/, '($1)');
} else if (newVal.length <= 6) {
newVal = newVal.replace(/^(\d{0,3})(\d{0,3})/, '($1) ($2)');
} else {
newVal = newVal.replace(/^(\d{0,3})(\d{0,3})(.*)/, '($1) ($2)-$3');
}
// set the new value
this.model.valueAccessor.writeValue(newVal);
}
}
@Component({
selector: 'my-app',
providers: [],

Unirest library simplifies this a lot. If you want to use it, you have to install unirest
npm package. Then your code could look like this:
unirest.get("http://graph.facebook.com/517267866/?fields=picture")
.send()
.end(response=> {
if (response.ok) {
console.log("Got a response: ", response.body.picture)
} else {
console.log("Got an error: ", response.error)
}
})
You can also configure your SSL in xampp/apache/conf/extra/httpd-vhost.conf
like this:
<VirtualHost *:443>
DocumentRoot C:/xampp/htdocs/yourProject
ServerName yourProject.whatever
SSLEngine on
SSLCertificateFile "conf/ssl.crt/server.crt"
SSLCertificateKeyFile "conf/ssl.key/server.key"
</VirtualHost>
I guess, it's better not change it in the httpd-ssl.conf
if you have more than one project and you need SSL on more than one of them
I was getting a null pointer exception during project creation related to "Dynamic Web Module".
To get the project to compile (that is, to javax.servlet
to import successfully) I had to go to project's Properties, pick Project Facets in the sidebar, tick Dynamic Web Module and click Apply.
Surprisingly, this time "Dynamic Web Module" facet installed correctly, and import started to work.
Starting from Apache HTTPComponents 4.3.x HttpClientBuilder class sets the proxy defaults from System properties http.proxyHost
and http.proxyPort
or else you can override them using setProxy method.
If you are just getting started with a new project then I would suggest that you use PDO instead of the old odbc_exec()
approach. Here is a simple example:
<?php
$bits = 8 * PHP_INT_SIZE;
echo "(Info: This script is running as $bits-bit.)\r\n\r\n";
$connStr =
'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
'Dbq=C:\\Users\\Gord\\Desktop\\foo.accdb;';
$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql =
"SELECT AgentName FROM Agents " .
"WHERE ID < ? AND AgentName <> ?";
$sth = $dbh->prepare($sql);
// query parameter value(s)
$params = array(
5,
'Homer'
);
$sth->execute($params);
while ($row = $sth->fetch()) {
echo $row['AgentName'] . "\r\n";
}
NOTE: The above approach is sufficient if you do not need to support Unicode characters above U+00FF
. If you do need to support such characters then neither PDO_ODBC
nor the old odbc_
functions will work; you'll need to use the solution described in this answer.
To mark a lambda async, simply prepend async
before its argument list:
// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
SQLiteUtils slu = new SQLiteUtils();
await slu.DeleteGroupAsync(groupName);
}));
import vs. include
The primary purpose of an import is to import a namespace. A more common use of the XSD import statement is to import a namespace which appears in another file. You might be gathering the namespace information from the file, but don't forget that it's the namespace that you're importing, not the file (don't confuse an import
statement with an include
statement).
Another area of confusion is how to specify the location or path of the included .xsd
file: An XSD import statement has an optional attribute named schemaLocation
but it is not necessary if the namespace of the import statement is at the same location (in the same file) as the import statement itself.
When you do chose to use an external .xsd
file for your WSDL, the schemaLocation
attribute becomes necessary. Be very sure that the namespace you use in the import statement is the same as the targetNamespace of the schema you are importing. That is, all 3 occurrences must be identical:
WSDL:
xs:import namespace="urn:listing3" schemaLocation="listing3.xsd"/>
XSD:
<xsd:schema targetNamespace="urn:listing3"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
Another approach to letting know the WSDL about the XSD is through Maven's pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<executions>
<execution>
<id>generate-sources-xmlbeans</id>
<phase>generate-sources</phase>
<goals>
<goal>xmlbeans</goal>
</goals>
</execution>
</executions>
<version>2.3.3</version>
<inherited>true</inherited>
<configuration>
<schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
</configuration>
</plugin>
You can read more on this in this great IBM article. It has typos such as xsd:import
instead of xs:import
but otherwise it's fine.
Problem solved, I've not added the index.html. Which is point out in the web.xml
Note: a project may have more than one web.xml file.
if there are another web.xml in
src/main/webapp/WEB-INF

src/main/webapp/WEB-INF/pages/
If you have latest compiler, you can change the following in your build settings:

Here is my totally functional approach which avoids having to read and split lines. It makes use of the itertools
module:
itertools.imap
with map
import itertools
def readwords(mfile):
byte_stream = itertools.groupby(
itertools.takewhile(lambda c: bool(c),
itertools.imap(mfile.read,
itertools.repeat(1))), str.isspace)
return ("".join(group) for pred, group in byte_stream if not pred)
Sample usage:
>>> import sys
>>> for w in readwords(sys.stdin):
... print (w)
...
I really love this new method of reading words in python
I
really

It's soo very Functional!
It's

I guess in your case, this would be the way to use the function:
with open('words.txt', 'r') as f:
for word in readwords(f):
print(word)
I had the same error here MacOSX 10.6.8 - it seems ruby checks to see if any directory (including the parents) in the path are world writable. In my case there wasn't a /usr/local/bin present as nothing had created it.
so I had to do
sudo chmod 775 /usr/local
to get rid of the warning.
A question here is does any non root:wheel process in MacOS need to create anything in /usr/local ?
Pure JSP comments look like this:
<%-- Comment --%>
So if you want to retain the "=
".you could do something like:
<%--= map.size() --%>
The key thing is that <%=
defines the beginning of an expression, in which you can't leave the body empty, but you could do something like this instead if the pure JSP comment doesn't appeal to you:
<% /*= map.size()*/ %>
Code Conventions for the JavaServer Pages Technology Version 1.x Language has details about the different commenting options available to you (but has a complete lack of link targets, so I can't link you directly to the relevant section - boo!)
Something like this:
select *
from User U1
where time_stamp = (
select max(time_stamp)
from User
where username = U1.username)
should do it.
Just for the sake of academic interest, I did it this way...
(dt.replace(month = dt.month % 12 +1, day = 1)-timedelta(days=1)).day

you can write to a unit, but you can also write to a string
program foo
character(len=1024) :: filename
write (filename, "(A5,I2)") "hello", 10
print *, trim(filename)
end program
Please note (this is the second trick I was talking about) that you can also build a format string programmatically.
program foo
character(len=1024) :: filename
character(len=1024) :: format_string
integer :: i
do i=1, 10
if (i < 10) then
format_string = "(A5,I1)"
else
format_string = "(A5,I2)"
endif
write (filename,format_string) "hello", i
print *, trim(filename)
enddo
end program
Do you have a local user.name
or user.email
that's overriding the global one?
git config --list --global | grep user
user.name=YOUR NAME
user.email=YOUR@EMAIL
git config --list --local | grep user
user.name=YOUR NAME
user.email=
If so, remove them
git config --unset --local user.name
git config --unset --local user.email
The local settings are per-clone, so you'll have to unset the local user.name
and user.email
for each of the repos on your machine.
Worked on 08/08/2018 and on DRF version 3.8.2:
class ItemSerializer(serializers.ModelSerializer):
category_name = serializers.ReadOnlyField(source='category.name')
class Meta:
model = Item
read_only_fields = ('id', 'category_name')
fields = ('id', 'category_name', 'name',)
Using the Meta read_only_fields
we can declare exactly which fields should be read_only. Then we need to declare the foreign
field on the Meta fields
(better be explicit as the mantra goes: zen of python).
You can get By Using this function.
console.log(this.$route.query.test)
From here.
If you create a file in your repo named .gitignore git will use its rules when looking at files to commit. Note that git will not ignore a file that was already tracked before a rule was added to this file to ignore it. In such a case the file must be un-tracked, usually with :
git rm --cached filename

I know this question has several answers already, but I think there is a very subtle aspect that, although mentioned, hasn't been highlighted enough in the previous answers.
Before checking the Apache configuration or your files' permissions, let's do a simpler check to make sure that each of the directories composing the full path to the file you want to access (e.g. the index.php file in your document's root) is not only readable but also executable by the web server user.
For example, let's say the path to your documents root is "/var/www/html". You have to make sure that all of the "var", "www" and "html" directories are (readable and) executable by the web server user. In my case (Ubuntu 16.04) I had mistakenly removed the "x" flag to the "others" group from the "html" directory so the permissions looked like this:
drwxr-xr-- 15 root root 4096 Jun 11 16:40 html
As you can see the web server user (to whom the "others" permissions apply in this case) didn't have execute access to the "html" directory, and this was exactly the root of the problem. After issuing a:
chmod o+x html
command, the problem got fixed!
Before resolving this way I had literally tried every other suggestion in this thread, and since the suggestion was buried in a comment that I found almost by chance, I think it may be helpful to highlight and expand on it here.
I'm very late to this game, but my problem started when I upgraded php on my server. I was able to just remove the .socket file and restart my services. Then, everything worked. Not sure why it made a difference, since the file is size 0 and the ownership and permissions are the same, but it worked.
If you only want to replace some characters you could use this:
import re
print re.sub(r'([\.\\\+\*\?\[\^\]\$\(\)\{\}\!\<\>\|\:\-])', r'\\\1', "example string.")
Sub TEST()
Dim value1 As String
Dim value2 As String
value1 = ThisWorkbook.Sheets(1).Range("A1").Value 'value from sheet1
value2 = ThisWorkbook.Sheets(2).Range("A1").Value 'value from sheet2
If value1 = value2 Then ThisWorkbook.Sheets(2).Range("L1").Value = value1 'or 2
End Sub
This will compare two sheets cells values and if they match place the value on sheet 2 in column L.
My favourite answer so far is coloredEcho.
Just to post another option, you can check out this little tool xcol
https://ownyourbits.com/2017/01/23/colorize-your-stdout-with-xcol/
you use it just like grep, and it will colorize its stdin with a different color for each argument, for instance
sudo netstat -putan | xcol httpd sshd dnsmasq pulseaudio conky tor Telegram firefox "[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+" ":[[:digit:]]+" "tcp." "udp." LISTEN ESTABLISHED TIME_WAIT
Note that it accepts any regular expression that sed will accept.
This tool uses the following definitions
#normal=$(tput sgr0) # normal text
normal=$'\e[0m' # (works better sometimes)
bold=$(tput bold) # make colors bold/bright
red="$bold$(tput setaf 1)" # bright red text
green=$(tput setaf 2) # dim green text
fawn=$(tput setaf 3); beige="$fawn" # dark yellow text
yellow="$bold$fawn" # bright yellow text
darkblue=$(tput setaf 4) # dim blue text
blue="$bold$darkblue" # bright blue text
purple=$(tput setaf 5); magenta="$purple" # magenta text
pink="$bold$purple" # bright magenta text
darkcyan=$(tput setaf 6) # dim cyan text
cyan="$bold$darkcyan" # bright cyan text
gray=$(tput setaf 7) # dim white text
darkgray="$bold"$(tput setaf 0) # bold black = dark gray text
white="$bold$gray" # bright white text
I use these variables in my scripts like so
echo "${red}hello ${yellow}this is ${green}coloured${normal}"
I found the default JS date formatting didn't work.
So I used toLocaleString
with options
const event = new Date();
const options = { dateStyle: 'short' };
const date = event.toLocaleString('en', options);
to get: DD/MM/YYYY format
See docs for more formatting options: https://www.w3schools.com/jsref/jsref_tolocalestring.asp
I had a same problem, and I solved my problem.
First go to config.default.php
and change
$cfg['Servers'][$i]['AllowNoPassword'] = false;
to
$cfg['Servers'][$i]['AllowNoPassword'] = true;
I find it easier to remember to just read it and then write it.
For example:
with open('file') as f:
data = f.read()
with open('file', 'w') as f:
f.write('hello')
I encountered with this issue spending couple of hours, however solved it in different ways. You can see, I have just created an assets folder outside application folder. Finally I linked my style sheet in the page header section. Folder structure are below images.
Before action this you should include url helper file either in your controller class method/__constructor files or by in autoload.php file. Also change $config['base_url'] = 'http://yoursiteurl';
in the following file application/config/config.php
If you include it in controller class method/__constructor then it look like
public function __construct()
{
$this->load->helper('url');
}
or If you load in autoload file then it would looks like
$autoload['helper'] = array('url');
Finally, add your stylesheet file. You can link a style sheet by different ways, include it in your inside section
-><link rel="stylesheet" href="<?php echo base_url();?>assets/css/style.css" type="text/css" />
-> or
<?php
$main = array(
'href' => 'assets/css/style.css',
'rel' => 'stylesheet',
'type' => 'text/css',
'title' => 'main stylesheet',
'media' => 'all',
'index_page' => true
);
echo link_tag($main); ?>
-> or
finally I get more reliable code cleaner concept. Just create a config file, named styles.php in you application/config/styles.php folder. Then add some links in styles.php file looks like below
<?php
$config['style'] = array(
'main' => array(
'href' => 'assets/css/style.css',
'rel' => 'stylesheet',
'type' => 'text/css',
'title' => 'main stylesheet',
'media' => 'all',
'index_page' => true
)
);
?>
call/add this config to your controller class method looks like below
$this->config->load('styles');
$data['style'] = $this->config->config['style'];
Pass this data in your header template looks like below.
$this->load->view('templates/header', $data);
And finally add or link your css file looks like below.
<?php echo link_tag($style['main']); ?>
The problem with all of these answers for me was they weren't responsive. I had to have a fixed height for a parent div which i didn't want. I also didn't want to spend a ton of time dinking around with media queries. If you are using angular, you can use bootstraps tabset and it will do all of the hard work for you. You'll be able to scroll the inner content and it will be responsive. When you setup the tab, do it like this: $scope.tab = { title: '', url: '', theclass: '', ative: true };
... the point is, you don't want a title or image icon. then hide the outline of the tab in cs like this:
.nav-tabs {
border-bottom:none;
}
and also this .nav-tabs > li.active > a, .nav-tabs > li.active > a:hover, .nav-tabs > li.active > a:focus {border:none;}
and finally to remove the invisible tab that you can still click on if you don't implement this: .nav > li > a {padding:0px;margin:0px;}
inetmgr then come to Application pool->Advanced setting of your pool-> will have the option "Enable 32-Bit Applications" set to true; and restart IIS. check again.!
This works:

As Nikola pointed out in the comment below, in case the backup URL is invalid as well, some browsers will trigger the "error" event again which will result in an infinite loop. We can guard against this by simply nullifying the "error" handler via this.onerror=null;
.
You can achieved what you want by creating a .css file and link to your <head>
tag just after the </title>
(closing title tag).
Hi-Resolution image will be good to use, around 2112x1584 pixels but consider the file size because it will matter for the page load time.
On the opening of your <body>
tag, just delete the background property as it will be declared through the .css file.
When your image is ready, put this code to your .css file
body {
background-image: url(imagePAth/Indian_wallpapers_205.jpg); /*You will specify your image path here.*/
-moz-background-size: cover;
-webkit-background-size: cover;
background-size: cover;
background-position: top center !important;
background-repeat: no-repeat !important;
background-attachment: fixed;
}
When your .css file is done, you can link it to the <head>
tag. It will look something like this: <link rel="stylesheet" type="text/css" href="yourCSSpath/yourCSSname.css" />
That's how i make a background image to fit the browser screen.
If you are using JSP 2.0 and above It will come with the EL support:
so that you can write in plain english and use and
with empty
operators to write your test:
<c:if test="${(empty object_1.attribute_A) and (empty object_2.attribute_B)}">
You put <=
and it will catch the given date too. You can replace it with <
only.
Basically you can create a regex to fulfil your needs and then assign that pattern to your input field.
Or for a more direct approach:
<input type="number" require ng-pattern="<your regex here>">

Have a look at CASE statements
http://msdn.microsoft.com/en-us/library/ms181765.aspx
You can use getString
String name = jsonObject.getString("name");
// it will throws exception if the key you specify doesn't exist
or optString
String name = jsonObject.optString("name");
// it will returns the empty string ("") if the key you specify doesn't exist
First you need to define the List
as :
List<Map<String, ArrayList<String>>> list = new ArrayList<>();
To add the Map
to the List
, use add(E e) method :
list.add(map);
There's no prepackaged "do-while", but the general Python way to implement peculiar looping constructs is through generators and other iterators, e.g.:
import itertools
def dowhile(predicate):
it = itertools.repeat(None)
for _ in it:
yield
if not predicate(): break
so, for example:
i=7; j=3
for _ in dowhile(lambda: i<j):
print i, j
i+=1; j-=1
executes one leg, as desired, even though the predicate's already false at the start.
It's normally better to encapsulate more of the looping logic into your generator (or other iterator) -- for example, if you often have cases where one variable increases, one decreases, and you need a do/while loop comparing them, you could code:
def incandec(i, j, delta=1):
while True:
yield i, j
if j <= i: break
i+=delta; j-=delta
which you can use like:
for i, j in incandec(i=7, j=3):
print i, j
It's up to you how much loop-related logic you want to put inside your generator (or other iterator) and how much you want to have outside of it (just like for any other use of a function, class, or other mechanism you can use to refactor code out of your main stream of execution), but, generally speaking, I like to see the generator used in a for
loop that has little (ideally none) "loop control logic" (code related to updating state variables for the next loop leg and/or making tests about whether you should be looping again or not).
You need to define the size of file...
header('Content-Length: ' . filesize($file));
And this line is wrong:
header("Content-Disposition:inline;filename='$filename");
You messed up quotas.
Minimal runnable example
For this to make sense, you have to understand the basics of paging: How does x86 paging work? and in particular that the OS can allocate virtual memory via page tables / its internal memory book keeping (VSZ virtual memory) before it actually has a backing storage on RAM or disk (RSS resident memory).
Now to observe this in action, let's create a program that:

which by the 128 + signal number rule means we got signal number 9
, which man 7 signal
says is SIGKILL, which is sent by the Linux out-of-memory killer.
Output interpretation:
printf '0x%X\n' 0x40009A4 KiB ~= 64GiB
(ps

, which means we haven't yet touched any pages. RSS is a small 1648 KiB
which has been allocated for normal program startup like text area, globals, etc.8388608 KiB == 8GiB
worth of pages. As a result, RSS increased by exactly 8GIB to 8390256 KiB == 8388608 KiB + 1648 KiB

OOM killer logs
Our dmesg
commands have shown the OOM killer logs.
An exact interpretation of those has been asked at:
The very first line of the log was:
[ 7283.479087] mongod invoked oom-killer: gfp_mask=0x6200ca(GFP_HIGHUSER_MOVABLE), order=0, oom_score_adj=0
So we see that interestingly it was the MongoDB daemon that always runs in my laptop on the background that first triggered the OOM killer, presumably when the poor thing was trying to allocate some memory.
However, the OOM killer does not necessarily kill the one who awoke it.
After the invocation, the kernel prints a table or processes including the oom_score
:
[ 7283.479292] [ pid ] uid tgid total_vm rss pgtables_bytes swapents oom_score_adj name
[ 7283.479303] [ 496] 0 496 16126 6 172032 484 0 systemd-journal
[ 7283.479306] [ 505] 0 505 1309 0 45056 52 0 blkmapd
[ 7283.479309] [ 513] 0 513 19757 0 57344 55 0 lvmetad
[ 7283.479312] [ 516] 0 516 4681 1 61440 444 -1000 systemd-udevd
and further ahead we see that our own little main.out
actually got killed on the previous invocation:
[ 7283.479871] Out of memory: Kill process 15665 (main.out) score 865 or sacrifice child
[ 7283.479879] Killed process 15665 (main.out) total-vm:67111332kB, anon-rss:92kB, file-rss:4kB, shmem-rss:30080832kB
[ 7283.479951] oom_reaper: reaped process 15665 (main.out), now anon-rss:0kB, file-rss:0kB, shmem-rss:30080832kB
This log mentions the score 865
which that process had, presumably the highest (worst) OOM killer score as mentioned at: https://unix.stackexchange.com/questions/153585/how-does-the-oom-killer-decide-which-process-to-kill-first
Also interestingly, everything apparently happened so fast that before the freed memory was accounted, the oom
was awoken again by the DeadlineMonitor
process:
[ 7283.481043] DeadlineMonitor invoked oom-killer: gfp_mask=0x6200ca(GFP_HIGHUSER_MOVABLE), order=0, oom_score_adj=0
and this time that killed some Chromium process, which is usually my computers normal memory hog:
[ 7283.481773] Out of memory: Kill process 11786 (chromium-browse) score 306 or sacrifice child
[ 7283.481833] Killed process 11786 (chromium-browse) total-vm:1813576kB, anon-rss:208804kB, file-rss:0kB, shmem-rss:8380kB
[ 7283.497847] oom_reaper: reaped process 11786 (chromium-browse), now anon-rss:0kB, file-rss:0kB, shmem-rss:8044kB

For everyone if you still strugle with Refusing connection, here is my advice. Download XAMPP or other similar sw and just start MySQL. You dont have to run apache or other things just the MySQL.
Assuming that you meant to state 'Class Diagram' instead of 'Project Hierarchy', I've used the following Eclipse plug-ins to generate Class Diagrams at various points in my professional career:
Obligatory links
The listed tools will not generate class diagrams from source code, or atleast when I used them quite a few years back. You can use them to handcraft class diagrams though.

Except for ObjectAid and a few other mentions, most of the Eclipse plug-ins mentioned in the listed questions may no longer be available, or would work only against older versions of Eclipse.
I think the poster meant to say You do not have to allocate everything on the
heap
rather than the the stack
.
Basically objects are allocated on the stack (if the object size allows, of course) because of the cheap cost of stack-allocation, rather than heap-based allocation which involves quite some work by the allocator, and adds verbosity because then you have to manage data allocated on the heap.
<md-input placeholder="Item name..." [(ngModel)]="name" (keyup)="filterResults()"></md-input>
<div *ngFor="let item of filteredValue">
{{item.name}}
</div>
filterResults() {
if (!this.name) {
this.filteredValue = [...this.items];
} else {
this.filteredValue = [];
this.filteredValue = this.items.filter((item) => {
return item.name.toUpperCase().indexOf(this.name.toUpperCase()) > -1;
});
}
}
Don't do any modification on 'items' array(list of items from which results are filtered). When searched item 'name' is empty return the complete list of 'items', if not compare the 'name' with every 'name' in the 'items ' array and filter out only the name that is present in 'items' array and store it in the 'filteredValue'.
Try this
df.drop(df.iloc[:, 1:69], inplace=True, axis=1)

If your test case runner returns a non-zero code for failed tests, you can simply write:
test_handler test_case_x; test_result=$?
if ((test_result != 0)); then
printf '%s\n' "Test case x failed" >&2 # write error message to stderr
exit 1 # or exit $test_result
fi
Or even shorter:
if ! test_handler test_case_x; then
printf '%s\n' "Test case x failed" >&2
exit 1
fi
Or the shortest:
test_handler test_case_x || { printf '%s\n' "Test case x failed" >&2; exit 1; }
To exit with test_handler's exit code:
test_handler test_case_x || { ec=$?; printf '%s\n' "Test case x failed" >&2; exit $ec; }
If you want to take a more comprehensive approach, you can have an error handler:
exit_if_error() {
local exit_code=$1
shift
[[ $exit_code ]] && # do nothing if no error code passed
((exit_code != 0)) && { # do nothing if error code is 0
printf 'ERROR: %s\n' "$@" >&2 # we can use better logging here
exit "$exit_code" # we could also check to make sure
# error code is numeric when passed
}
}
then invoke it after running your test case:
run_test_case test_case_x
exit_if_error $? "Test case x failed"
or
run_test_case test_case_x || exit_if_error $? "Test case x failed"
The advantages of having an error handler like exit_if_error
are:

this.folderImages.Items.RemoveAt(index);
this.folderImages.Items.Insert(index + 1, imageName);
this.folderImages.SelectedIndex = index + 1;
}
and this for moving it one place up:
if (this.folderImages.SelectedIndex > 0)
{
string imageName = this.folderImages.SelectedItem as string;
int index = this.folderImages.SelectedIndex;
this.folderImages.Items.RemoveAt(index);
this.folderImages.Items.Insert(index - 1, imageName);
this.folderImages.SelectedIndex = index - 1;
}
folderImages
is a ListBox
of course so the list is a ListBox.ObjectCollection
, not a List<T>
, but it does inherit from IList
so it should behave the same. Does this help?
Of course the former only works if the selected item is not the last item in the list and the latter if the selected item is not the first item.
In version 0.18.1
is added dt.weekday_name
:
print df
my_dates myvals
0 2015-01-01 1
1 2015-01-02 2
2 2015-01-03 3
print df.dtypes
my_dates datetime64[ns]
myvals int64
dtype: object
df['day_of_week'] = df['my_dates'].dt.weekday_name
print df
my_dates myvals day_of_week
0 2015-01-01 1 Thursday
1 2015-01-02 2 Friday
2 2015-01-03 3 Saturday
Another solution with assign
:
print df.assign(day_of_week = df['my_dates'].dt.weekday_name)
my_dates myvals day_of_week
0 2015-01-01 1 Thursday
1 2015-01-02 2 Friday
2 2015-01-03 3 Saturday
If no provider is enabled, "passive" is the best provider returned. See https://stackoverflow.com/a/4519414/621690

String provider = lm.getBestProvider(new Criteria(), true);

}
If you don't want to use a separate JS library to create a custom control for that, you could use two confirm
dialogs to do the checks:
if (confirm("Are you sure you want to quit?") ) {
if (confirm("Save your work before leaving?") ) {
// code here for save then leave (Yes)
} else {
//code here for no save but leave (No)
}
} else {
//code here for don't leave (Cancel)
}
I realize this question is old, but it recently popped up in a search I just ran, so I thought I'd post an alternative to the above answer.
If you are looking to generate create
scripts programmatically in .Net, I would highly recommend looking into Server Management Objects (SMO) or Distributed Management Objects (DMO) -- depending on which version of SQL Server you are using (the former is 2005+, the latter 2000). Using these libraries, scripting a table is as easy as:
Server server = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories = northwind.Tables["Categories"];
StringCollection script = categories.Script();
string[] scriptArray = new string[script.Count];
script.CopyTo(scriptArray, 0);

For removing all the elements from SparseArray
using the above looping leads to Exception

int key = sparseArray.keyAt(i);
Log.d("Element at "+key, " is "+sparseArray.get(key));
sparseArray.remove(key);
i=-1;

You're getting that because VARCHAR
is not a valid type to cast into. According to the MySQL docs (http://dev.mysql.com/doc/refman/5.5/en/cast-functions.html#function_cast) you can only cast to:
I think your best-bet is to use CHAR

I have same problem with pipenv
on Mac OS X 10.13 High Seirra, another Mac works just fine. I use Heroku to deploy my Django servers, some in 2.7 and some in 3.6. So, I need both 2.7 and 3.6. When HomeBrew install Python, it keeps python
points to original 2.7, and python3
points to 3.6.
The problem might due to $ pip install pipenv
. I checked /usr/local/bin and pipenv isn't there. So, I tried a full uninstall:
$ pip uninstall pipenv
Cannot uninstall requirement pipenv, not installed
You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
$ pip3 uninstall pipenv
Skipping pipenv as it is not installed.
Then reinstall and works now:
$ pip3 install pipenv

If you wirte to a .csv file in C++ - you should use the syntax of :
myfile <<" %s; %s; %d", string1, string2, double1 <<endl;
This will write the three variables (string 1&2 and double1) into separate columns and leave an empty row below them. In excel the ; means the new row, so if you want to just take a new row - you can alos write a simple ";" before writing your new data into the file. If you don't want to have an empty row below - you should delete the endl and use the:
myfile.open("result.csv", std::ios::out | std::ios::app);
syntax when opening the .csv file (example the result.csv). In this way next time you write something into your result.csv file - it will write it into a new row directly below the last one - so you can easily manage a for cycle if you would like to.
With an already accepted answer present, I think this is a better answer to the question on how to handle this on the inventory level. I consider this more secure by isolating this insecure setting to the hosts required for this (e.g. test systems, local development machines).
What you can do at the inventory level is add
ansible_ssh_common_args='-o StrictHostKeyChecking=no'
or
ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
to your host definition (see Ansible Behavioral Inventory Parameters).
This will work provided you use the ssh
connection type, not paramiko
or something else).
For example, a Vagrant host definition would look like…
vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_common_args='-o StrictHostKeyChecking=no'
or
vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
Running Ansible will then be successful without changing any environment variable.
$ ansible vagrant -i <path/to/hosts/file> -m ping
vagrant | SUCCESS => {
"changed": false,
"ping": "pong"
}
In case you want to do this for a group of hosts, here's a suggestion to make it a supplemental group var for an existing group like this:
[mytestsystems]
test[01:99].example.tld
[insecuressh:children]
mytestsystems
[insecuressh:vars]
ansible_ssh_common_args='-o StrictHostKeyChecking=no'
I think you should consider using IO.binread("/path/to/file")
if you have a recent ruby interpreter (i.e. >= 1.9.2)
You could find IO

You can read about jQuery Ajax from official jQuery Site: https://api.jquery.com/jQuery.ajax/
If you don't want to use any click event then you can set timer for periodically update.
Below code may be help you just example.
function update() {
$.get("response.php", function(data) {
$("#some_div").html(data);
window.setTimeout(update, 10000);
});
}
Above function will call after every 10 seconds and get content from response.php and update in #some_div
.
Alternative and fast solution : I faced the same error. I reopened the "wierd" csv file in GNUMERIC on my lubuntu machine and exported the file as csv file. This corrected the issue.
In Objective-C:
NSString *myString = myURL.absoluteString;
In Swift:
var myString = myURL.absoluteString
More info in the docs:
It turns out that my understanding of the error message was wrong. I'd say it features very poor choice of words. Googling around shown me someone else misunderstood the message exactly like I did - see PHP bug #66763.
After totally unhelpful "This is the way the RMs wanted it to be." response to that bug by Mike, Tyrael explains that setting it to "-1" doesn't make just the warning to go away. It does the right thing, i.e. it completely disables populating the culprit variable. Turns out that having it set to 0 STILL populates data under some circumstances. Talk about bad design! To cite PHP RFC:
Change always_populate_raw_post_data INI setting to accept three values instead of two.
- -1: The behavior of master; don't ever populate $GLOBALS[HTTP_RAW_POST_DATA]
- 0/off/whatever: BC behavior (populate if content-type is not registered or request method is other than POST)
- 1/on/yes/true: BC behavior (always populate $GLOBALS[HTTP_RAW_POST_DATA])
So yeah, setting it to -1 not only avoids the warning, like the message said, but it also finally disables populating this variable, which is what I wanted.
Use the menu selection Navigate -> Test, or Ctrl+Shift+T (Shift+?+T on Mac). This will go to the existing test class, or offer to generate it for you through a little wizard.

In order to use special characters, such as '>' on Windows with echo, you need to place a special escape character before it.
For instance
echo A->B
will not work since '>' has to be escaped by '^':
echo A-^>B
See also escape sequences.
There is a short batch file, which prints a basic set of special character and their escape sequences.
I've created a simple example on github using the above approach.
You are looking for a Sublime UI Theme, which modifies Sublime's User Interface (e.g.: side bar). It's different from a Color Theme/Scheme, which modifies only the code part of Sublime's window. I tested a lot of UI Themes and the one I liked the most was Theme - Soda. You can install it using Sublime's Package Control. To enable it, go to Preferences >> Settings - User and add this line:
"theme": "Soda Dark 3.sublime-theme",
Here is a printscreen of my Sublime Text 3 with Soda Dark UI Theme and Twilight default Color Scheme:
You can use the GTK glib to abstract from OS stuff.
glib provides a g_dir_open() function which should do the trick.

What I believe is this:
Cohesion refers to the degree to which the elements of a module/class belong together, it is suggested that the related code should be close to each other, so we should strive for high cohesion and bind all related code together as close as possible. It has to do with the elements within the module/class.
Coupling refers to the degree to which the different modules/classes depend on each other, it is suggested that all modules should be independent as far as possible, that's why low coupling. It has to do with the elements among different modules/classes.
To visualize the whole picture will be helpful:
The screenshot was taken from Coursera.
The model presents a placeholder to hold the information you want to display on the view. It could be a string, which is in your above example, or it could be an object containing bunch of properties.
Example 1
If you have...
return new ModelAndView("welcomePage","WelcomeMessage","Welcome!");
... then in your jsp, to display the message, you will do:-
Hello Stranger! ${WelcomeMessage} // displays Hello Stranger! Welcome!
Example 2
If you have...
MyBean bean = new MyBean();
bean.setName("Mike!");
bean.setMessage("Meow!");
return new ModelAndView("welcomePage","model",bean);
... then in your jsp, you can do:-
Hello ${model.name}! {model.message} // displays Hello Mike! Meow!

Taking Shiraz's idea and running with it...
In your application, are you explicitly defining a domain User Account and Password to access AD?
When you are executing the application explicitly it may be inherently using your credentials (your currently logged in domain account) to interrogate AD. However, when calling the application from the script, I'm not sure if the application is in the System context.
A VBScript example would be as follows:
Dim objConnection As ADODB.Connection
Set objConnection = CreateObject("ADODB.Connection")
objConnection.Provider = "ADsDSOObject"
objConnection.Properties("User ID") = "MyDomain\MyAccount"
objConnection.Properties("Password") = "MyPassword"
objConnection.Open "Active Directory Provider"
If this works, of course it would be best practice to create and use a service account specifically for this task, and to deny interactive login to that account.
Swift 3 | UIDeviceOrientationDidChange Notification Observed Too Often
The following code prints "deviceDidRotate" every time your device changes orientation in 3D space - regardless of a change from portrait to landscape orientation. For example, if you hold your phone in portrait orientation and tilt it forward and backward - deviceDidRotate() is called repeatedly.
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(
self,
selector: #selector(deviceDidRotate),
name: .UIDeviceOrientationDidChange,
object: nil
)
}
func deviceDidRotate() {
print("deviceDidRotate")
}
To work around this you could hold the previous device orientation and check for a change in deviceDidRotate().
var previousDeviceOrientation: UIDeviceOrientation = UIDevice.current.orientation
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(
self,
selector: #selector(deviceDidRotate),
name: .UIDeviceOrientationDidChange,
object: nil
)
}
func deviceDidRotate() {
if UIDevice.current.orientation == previousDeviceOrientation { return }
previousDeviceOrientation = UIDevice.current.orientation
print("deviceDidRotate")
}
Or you can use a different notification that only gets called when the device changes from landscape to portrait. In this case you'd want to use the UIApplicationDidChangeStatusBarOrientation
notification.
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(
self,
selector: #selector(deviceDidRotate),
name: .UIApplicationDidChangeStatusBarOrientation,
object: nil
)
}
func deviceDidRotate() {
print("deviceDidRotate")
}
you would put them inside a <p>
or a <div>

Usage:
<script src="bjax.min.js" type="text/javascript"></script>
<link href="bjax.min.css" rel="stylesheet" type="text/css" />
Finally, include this in the HEAD of your html:
$('a').bjax();

You can create a DIV
component using the <h:panelGroup/>
.
By default, the <h:panelGroup/>
will generate a SPAN in the HTML code.
However, if you specify layout="block"
, then the component will be a DIV
in the generated HTML code.
<h:panelGroup layout="block"/>
The one liner to get true postives etc. out of the confusion matrix is to ravel it:
from sklearn.metrics import confusion_matrix
y_true = [1, 1, 0, 0]
y_pred = [1, 0, 1, 0]
tn, fp, fn, tp = confusion_matrix(y_true, y_pred).ravel()
print(tn, fp, fn, tp) # 1 1 1 1

extension UIButton {
override open var isEnabled: Bool {
didSet {
DispatchQueue.main.async {
if self.isEnabled {
self.alpha = 1.0
}
else {
self.alpha = 0.6
}
}
}
}
}
How to use
myButton.isEnabled = false
import * as fs from 'fs';
import * as path from 'path';
fs.readFile(path.join(__dirname, "filename.txt"), (err, data) => {
if (err) throw err;
console.log(data);
})
EDIT:
consider the project structure:
../readfile/
+-- filename.txt
+-- src
+-- index.js
+-- index.ts
consider the index.ts
:
import * as fs from 'fs';
import * as path from 'path';
function lookFilesInDirectory(path_directory) {
fs.stat(path_directory, (err, stat) => {
if (!err) {
if (stat.isDirectory()) {
console.log(path_directory)
fs.readdirSync(path_directory).forEach(file => {
console.log(`\t${file}`);
});
console.log();
}
}
});
}
let path_view = './';
lookFilesInDirectory(path_view);
lookFilesInDirectory(path.join(__dirname, path_view));
if you have in the readfile folder and run tsc src/index.ts && node src/index.js
, the output will be:
./
filename.txt
src
/home/andrei/scripts/readfile/src/
index.js
index.ts
that is, it depends on where you run the node.
the __dirname is directory name of the current module.
You could make your own plugins.
jQuery.fn.visible = function() {

};
jQuery.fn.visibilityToggle = function() {
return this.css('visibility', function(i, visibility) {
return (visibility == 'visible') ? 'hidden' : 'visible';
});
};
If you want to overload the original jQuery toggle()
, which I don't recommend...
!(function($) {
var toggle = $.fn.toggle;
$.fn.toggle = function() {
var args = $.makeArray(arguments),
lastArg = args.pop();
if (lastArg == 'visibility') {

If you truly cannot have proper encryption and hash keys but have to use an user entered password as the only secret, you can do something like this:
/**
* @param string $password user entered password as the only source of
* entropy to generate encryption key and hash key.
* @return array($encryption_key, $hash_key) - note that PBKDF2 algorithm
* has been configured to take around 1-2 seconds per conversion
* from password to keys on a normal CPU to prevent brute force attacks.
*/

{
$hash = hash_pbkdf2("sha512", "$password", "salt$password", 1500000);
return str_split($hash, 64);
}
string1.equals(string2)
is right way to do it.
String s = "something", t = "maybe something else";
if (s == t) // Legal, but usually results WRONG.
if (s.equals(t)) // RIGHT way to check the two strings
/* == will fail in following case:*/
String s1 = new String("abc");
String s2 = new String("abc");
if(s1==s2) //it will return false
You can specify the type of a variable before it to force its type. It's called (dynamic) casting (more information is here):
$string = "1654"
$integer = [int]$string
$string + 1
# Outputs 16541
$integer + 1
# Outputs 1655
As an example, the following snippet adds, to each object in $fileList
, an IntVal
property with the integer value of the Name
property, then sorts $fileList
on this new property (the default is ascending), takes the last (highest IntVal
) object's IntVal
value, increments it and finally creates a folder named after it:
# For testing purposes
#$fileList = @([PSCustomObject]@{ Name = "11" }, [PSCustomObject]@{ Name = "2" }, [PSCustomObject]@{ Name = "1" })
# OR
#$fileList = New-Object -TypeName System.Collections.ArrayList
#$fileList.AddRange(@([PSCustomObject]@{ Name = "11" }, [PSCustomObject]@{ Name = "2" }, [PSCustomObject]@{ Name = "1" })) | Out-Null
$highest = $fileList |
Select-Object *, @{ n = "IntVal"; e = { [int]($_.Name) } } |
Sort-Object IntVal |
Select-Object -Last 1
$newName = $highest.IntVal + 1
New-Item $newName -ItemType Directory
Sort-Object IntVal
is not needed so you can remove it if you prefer.
[int]::MaxValue = 2147483647
so you need to use the [long]
type beyond this value ([long]::MaxValue = 9223372036854775807
).
I would always encode in UTF-8. From the Wikipedia page on percent encoding:
The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values. This requirement was introduced in January 2005 with the publication of RFC 3986. URI schemes introduced before this date are not affected.
It seems like because there were other accepted ways of doing URL encoding in the past, browsers attempt several methods of decoding a URI, but if you're the one doing the encoding you should use UTF-8.
Note: the selected answer is changing the array order which is not preferred, here I provide more different variations that achieving the same result and keeping the array in order
given [98.88, .56, .56]
how do you want to round it? you have four option
1- round things up and subtract what is added from the rest of the numbers, so the result becomes [98, 1, 1]
this could be a good answer, but what if we have [97.5, .5, .5, .5, .5, .5]
? then you need to round it up to [95, 1, 1, 1, 1, 1]
do you see how it goes? if you add more 0-like numbers, you will lose more value from the rest of your numbers. this could be very troublesome when you have a big array of zero-like number like [40, .5, .5 , ... , .5]
. when you round up this, you could end up with an array of ones: [1, 1, .... , 1]
so round-up isn't a good option.
2- you round down the numbers. so [98.88, .56, .56]
becomes [98, 0, 0]
, then you are 2 less than 100. you ignore anything that is already 0, then add up the difference to the biggest numbers. so bigger numbers will get more.
3- same as previous, round down numbers, but you sort descending based on the decimals, divide up the diff based on the decimal, so biggest decimal will get the diff.
4- you round up, but you add what you added to the next number. so like a wave what you have added will be redirected to the end of your array. so [98.88, .56, .56]
becomes [99, 0, 1]
none of these are ideal, so be mindful that your data is going to lose its shape.
here I provide a code for cases 2 and 3 (as case No.1 is not practical when you have a lot of zero-like numbers). it's modern Js and doesn't need any library to use
const v1 = [13.626332, 47.989636, 9.596008, 28.788024];// => [ 14, 48, 9, 29 ]
const v2 = [16.666, 16.666, 16.666, 16.666, 16.666, 16.666] // => [ 17, 17, 17, 17, 16, 16 ]
const v3 = [33.333, 33.333, 33.333] // => [ 34, 33, 33 ]

Do you have the right permissions to write to SD card in your manifest ? Look for WRITE_EXTERNAL_STORAGE at http://developer.android.com/reference/android/Manifest.permission.html
If you know, or can enforce the size for the to-be-upper element, you could use
position : absolute;
In your css and give the divs their position.
otherwise javascript seems the only way to go:
fd = document.getElementById( 'firstDiv' );
sd = document.getElementById( 'secondDiv' );
fd.parentNode.removeChild( fd );
sd.parentNode.insertAfter( fd, sd );
or something similar.

The -i
flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/
).
So in your first command, you are actually asking scp
to upload the .pem file itself using your default ssh key. I don't think that is what you want.
Try instead with:
scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads
Basically, the first model you are using is called as document-based storage. You should have a look at popular NoSQL document-based database like MongoDB and CouchDB. Basically, in document based db's, you store data in json files and then you can query on these json files.
The Second model is the popular relational database structure.
If you want to use relational database like MySql then i would suggest you to only use second model. There is no point in using MySql and storing data as in the first model.
To answer your second question, there is no way to query name like 'foo' if you use first model.
There is a typo error :

To make everything writable by the owner, read/execute by the group, and world executable:

Combining two of the previous results, we have:
int(round(some_float))
This converts a float to an integer fairly dependably.
This is how the JDK does it (adapted from OpenJDK 8, String.java/regionMatches):
static boolean charactersEqualIgnoringCase(char c1, char c2) {
if (c1 == c2) return true;
// If characters don't match but case may be ignored,
// try converting both characters to uppercase.
char u1 = Character.toUpperCase(c1);
char u2 = Character.toUpperCase(c2);
if (u1 == u2) return true;
// Unfortunately, conversion to uppercase does not work properly
// for the Georgian alphabet, which has strange rules about case
// conversion. So we need to make one last check before
// exiting.
return Character.toLowerCase(u1) == Character.toLowerCase(u2);
}
I suppose that works for Turkish too.
You are comparing two objects for equality. The snippet:
if (obj == this) { return true; }
is a quick test that can be read
"If the object I'm comparing myself to is me, return true"
. You usually see this happen in equals
methods so they can exit early and avoid other costly comparisons.
This works with multiple statements:
if condition1 Then stmt1:stmt2 Else if condition2 Then stmt3:stmt4 Else stmt5:stmt6
Or you can split it over multiple lines:
if condition1 Then stmt1:stmt2
Else if condition2 Then stmt3:stmt4
Else stmt5:stmt6

If you use several different versions of python try using virtualenv
http://www.virtualenv.org/en/latest/virtualenv.html#installation
With the advantage of pip
for each local environment.
Then install a local environment in the current directory by:
virtualenv -p /usr/local/bin/python3.3 ENV --verbose
Note that you specify the path to a python binary you have installed on your system.
Then there are now an local pythonenvironment in that folder. ./ENV
Now there should be ./ENV/pip-3.3
use
./ENV/pip-3.3 freeze
to list the local installed libraries.
use ./ENV/pip-3.3 install packagename
to install at the local environment.
use ./ENV/python3.3 pythonfile.py
to run your python script.
This should be OK, but is Internet Explorer specific:

In addition to this, due to some recent website hacks we had to secure our sites more. In doing so, we discovered that file_get_contents failed to work, where curl still would work.

The rule for using spinlocks is simple: use a spinlock if and only if the real time the lock is held is bounded and sufficiently small.
Note that usually user implemented spinlocks DO NOT satisfy this requirement because they do not disable interrupts. Unless pre-emptions are disabled, a pre-emption whilst a spinlock is held violates the bounded time requirement.
Sufficiently small is a judgement call and depends on the context.
Exception: some kernel programming must use a spinlock even when the time is not bounded. In particular if a CPU has no work to do, it has no choice but to spin until some more work turns up.
Special danger: in low level programming take great care when multiple interrupt priorities exist (usually there is at least one non-maskable interrupt). In this higher priority pre-emptions can run even if interrupts at the thread priority are disabled (such as priority hardware services, often related to the virtual memory management). Provided a strict priority separation is maintained, the condition for bounded real time must be relaxed and replaced with bounded system time at that priority level. Note in this case not only can the lock holder be pre-empted but the spinner can also be interrupted; this is generally not a problem because there's nothing you can do about it.
I have started Activity A->B->C->D. When the back button is pressed on Activity D I want to go to Activity A. Since A is my starting point and therefore already on the stack all the activities in top of A is cleared and you can't go back to any other Activity from A.
This actually works in my code:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
Intent a = new Intent(this,A.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(a);
return true;
}
return super.onKeyDown(keyCode, event);
}
C++ is mostly a superset of C. You can continue doing what you were doing.
That said, in C++, what you ought to do is to define a proper Matrix class that manages its own memory. It could, for example be backed by an internal std::vector
, and you could override operator[]
or operator()
to index into the vector appropriately (for example, see: How do I create a subscript operator for a Matrix class? from the C++ FAQ).
To get you started:
class Matrix
{
public:
Matrix(size_t rows, size_t cols);
double& operator()(size_t i, size_t j);
double operator()(size_t i, size_t j) const;
private:
size_t mRows;
size_t mCols;
std::vector<double> mData;
};
Matrix::Matrix(size_t rows, size_t cols)
: mRows(rows),
mCols(cols),
mData(rows * cols)
{
}
double& Matrix::operator()(size_t i, size_t j)
{
return mData[i * mCols + j];
}
double Matrix::operator()(size_t i, size_t j) const
{
return mData[i * mCols + j];
}
(Note that the above doesn't do any bounds-checking, and I leave it as an exercise to template it so that it works for things other than double
.)
My answer is based on this answer: How can I get the current contents of an element in webdriver just more like copy-paste.

The ALL_DIRECTORIES
data dictionary view will have information about all the directories that you have access to. That includes the operating system path
SELECT owner, directory_name, directory_path
FROM all_directories
The best way is to prevent the default action. In the case of anchor tag, the default behavior is redirecting to href
specified address.
So following javascript works best in the situation:
$('#ThisLink').click(function(e)
{
e.preventDefault();
});
SELECT *
FROM myTable
WHERE URL = LEFT('mysyte.com/?id=2®ion=0&page=1', LEN(URL))
Or use CHARINDEX http://msdn.microsoft.com/en-us/library/aa258228(v=SQL.80).aspx
select owner, table_name, num_rows, sample_size, last_analyzed from all_tables;
This is the fastest way to retrieve the row counts but there are a few important caveats:
ESTIMATE_PERCENT => DBMS_STATS.AUTO_SAMPLE_SIZE
(the default), or in earlier versions with ESTIMATE_PERCENT => 100
. See this post for an explanation of how
the AUTO_SAMPLE_SIZE algorithm works in 11g.LAST_ANALYZED
, the current results may be different.You have a lot of variants for using @RequestParam
with additional optional elements, e.g.
@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr
If you don't put required = false
- param will be required by default.
defaultValue = "someValue"
- the default value to use as a fallback when the request parameter is not provided or has an empty value.
If request and method param are the same - you don't need value = "someAttr"
There are a couple of things that need to be adjusted in your layout:
You are nesting col
elements within form-group
elements. This should be the other way around (the form-group
should be within the col-sm-xx
element).
You should always use a row
div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12
is still on the same row with the above 3 .col-sm-4
resulting in a total of columns greater than 12, and causing the overlap problem.
Here is a fixed demo.
And an excerpt of what the problematic section HTML should become:
<fieldset>
<legend>Personal Information</legend>
<div class='row'>
<div class='col-sm-4'>
<div class='form-group'>
<label for="user_title">Title</label>
<input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
</div>
</div>
<div class='col-sm-4'>
<div class='form-group'>
<label for="user_firstname">First name</label>
<input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />
</div>
</div>
<div class='col-sm-4'>
<div class='form-group'>
<label for="user_lastname">Last name</label>
<input class="form-control" id="user_lastname" name="user[lastname]" required="true" size="30" type="text" />
</div>
</div>
</div>
<div class='row'>

Great question. There are three solutions I know about:
Solution #1
Replace the default widget.
class SearchForm(forms.Form):
q = forms.CharField(
label='Search',
widget=forms.TextInput(attrs={'placeholder': 'Search'})
)
Solution #2
Customize the default widget. If you're using the same widget that the field usually uses then you can simply customize that one instead of instantiating an entirely new one.
class SearchForm(forms.Form):
q = forms.CharField(label='Search')
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['q'].widget.attrs.update({'placeholder': 'Search'})
Solution #3
Finally, if you're working with a model form then (in addition to the previous two solutions) you have the option to specify a custom widget for a field by setting the widgets
attribute of the inner Meta
class.
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
widgets = {
'body': forms.Textarea(attrs={'cols': 80, 'rows': 20})
}
Appart from setting maven source url to your gradle, I would suggest to add both design and appcompat libraries. Currently the latest version is 26.1.0

Java array reflection is for cases where you don't have an instance of the Class available to do "instanceof" on. For example, if you're writing some sort of injection framework, that injects values into a new instance of a class, such as JPA does, then you need to use the isArray() functionality.
I blogged about this earlier in December. http://blog.adamsbros.org/2010/12/08/java-array-reflection/
Divide $percentage
by 100 and multiply to $totalWidth
. Simple maths.
If the code in your question doesn't work, you probably have not implemented equals(Object)
on the Customer
class appropriately.
Presumably there is some key (let us call it customerId
) that uniquely identifies a customer; e.g.
class Customer {
private String customerId;
...
An appropriate definition of equals(Object)
would look like this:
public boolean equals(Object obj) {
if (obj == this) {
return true;
}
if (!(obj instanceof Customer)) {
return false;
}
Customer other = (Customer) obj;
return this.customerId.equals(other.customerId);
}
For completeness, you should also implement hashCode
so that two Customer
objects that are equal will return the same hash value. A matching hashCode
for the above definition of equals
would be:
public int hashCode() {
return customerId.hashCode();
}
It is also worth noting that this is not an efficient way to remove duplicates if the list is large. (For a list with N customers, you will need to perform N*(N-1)/2
comparisons in the worst case; i.e. when there are no duplicates.) For a more efficient solution you should use something like a HashSet
to do the duplicate checking.

I wrote this answer about four years ago and my opinion hasn't changed. But since then there have been significant developments on the micro-services front. I added micro-services specific notes at the end...
I'll weigh in against the idea, with real-world experience to back up my vote.
I was brought on to a large application that had five contexts for a single database. In the end, we ended up removing all of the contexts except for one - reverting back to a single context.
At first the idea of multiple contexts seems like a good idea. We can separate our data access into domains and provide several clean lightweight contexts. Sounds like DDD, right? This would simplify our data access. Another argument is for performance in that we only access the context that we need.
But in practice, as our application grew, many of our tables shared relationships across our various contexts. For example, queries to table A in context 1 also required joining table B in context 2.
This left us with a couple poor choices. We could duplicate the tables in the various contexts. We tried this. This created several mapping problems including an EF constraint that requires each entity to have a unique name. So we ended up with entities named Person1 and Person2 in the different contexts. One could argue this was poor design on our part, but despite our best efforts, this is how our application actually grew in the real world.
We also tried querying both contexts to get the data we needed. For example, our business logic would query half of what it needed from context 1 and the other half from context 2. This had some major issues. Instead of performing one query against a single context, we had to perform multiple queries across different contexts. This has a real performance penalty.
In the end, the good news is that it was easy to strip out the multiple contexts. The context is intended to be a lightweight object. So I don't think performance is a good argument for multiple contexts. In almost all cases, I believe a single context is simpler, less complex, and will likely perform better, and you won't have to implement a bunch of work-arounds to get it to work.
I thought of one situation where multiple contexts could be useful. A separate context could be used to fix a physical issue with the database in which it actually contains more than one domain. Ideally, a context would be one-to-one to a domain, which would be one-to-one to a database. In other words, if a set of tables are in no way related to the other tables in a given database, they should probably be pulled out into a separate database. I realize this isn't always practical. But if a set of tables are so different that you would feel comfortable separating them into a separate database (but you choose not to) then I could see the case for using a separate context, but only because there are actually two separate domains.
Regarding micro-services, one single context still makes sense. However, for micro-services, each service would have its own context which includes only the database tables relevant to that service. In other words, if service x accesses tables 1 and 2, and service y accesses tables 3 and 4, each service would have its own unique context which includes tables specific to that service.
I'm interested in your thoughts.
For me this problem arised while trying to connect to the SAP Hana database. When I got this error,
OperationalError: Lost connection to HANA server (ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))
I tried to run the code for connection(mentioned below), which created that error, again and it worked.
import pyhdb connection = pyhdb.connect(host="example.com",port=30015,user="user",password="secret") cursor = connection.cursor() cursor.execute("SELECT 'Hello Python World' FROM DUMMY") cursor.fetchone() connection.close()
It was because the server refused to connect. It might require you to wait for a while and try again. Try closing the Hana Studio by logging off and then logging in again. Keep running the code for a number of times.
public class Person{
String s;
Date d;
...
public Person clone(){
Person p = new Person();
p.s = this.s.clone();
p.d = this.d.clone();
...
return p;
}
}
In your executing code:
ArrayList<Person> clone = new ArrayList<Person>();
for(Person p : originalList)
clone.add(p.clone());
I answered a very similar question:

You simply need to iterate over the series' .Points
collection, and then you can assign the points' .Format.Fill.ForeColor.RGB
value based on whatever criteria you need.
UPDATED
The code below will color the chart per the screenshot. This only assumes three colors are used. You can add additional case statements for other color values, and update the assignment of myColor
to the appropriate RGB values for each.
Option Explicit
Sub ColorScatterPoints()
Dim cht As Chart
Dim srs As Series
Dim pt As Point
Dim p As Long
Dim Vals$, lTrim#, rTrim#
Dim valRange As Range, cl As Range
Dim myColor As Long
Set cht = ActiveSheet.ChartObjects(1).Chart
Set srs = cht.SeriesCollection(1)
'## Get the series Y-Values range address:
lTrim = InStrRev(srs.Formula, ",", InStrRev(srs.Formula, ",") - 1, vbBinaryCompare) + 1
rTrim = InStrRev(srs.Formula, ",")
Vals = Mid(srs.Formula, lTrim, rTrim - lTrim)
Set valRange = Range(Vals)
For p = 1 To srs.Points.Count
Set pt = srs.Points(p)
Set cl = valRange(p).Offset(0, 1) '## assume color is in the next column.
With pt.Format.Fill
.Visible = msoTrue
'.Solid 'I commented this out, but you can un-comment and it should still work
'## Assign Long color value based on the cell value
'## Add additional cases as needed.
Select Case LCase(cl)
Case "red"
myColor = RGB(255, 0, 0)
Case "orange"
myColor = RGB(255, 192, 0)
Case "green"
myColor = RGB(0, 255, 0)
End Select
.ForeColor.RGB = myColor

our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."
right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.
This seems to be similar to this issue: False "Property does not exist on type 'never'" when changing value inside callback with strictNullChecks
, which is closed as a duplicate of this issue (discussion): Trade-offs in Control Flow Analysis.
That discussion is pretty long, if you can't find a good solution there you can try this:

console.log('Instance is null or undefined');
} else {
console.log(instance!.name); // ok now
}

Forgive me if someone already mentioned, but in the days of x86 when memory segmentation was still relevant, you may not get the same results from these two instructions:
LEA AX, DS:[0x1234]
and
LEA AX, CS:[0x1234]
You will need something more that a http request to interact with a WCF service UNLESS your WCF service has a REST interface. Either look for a SOAP web service API that runs on android or make your service RESTful. You will need .NET 3.5 SP1 to do WCF REST services:
You might don't need any web site for that, only open up the browser, press F12
to get access to developer tools > console, then in console write some JavaScript Code to do that.
Here I share some ways to accomplish that:
For GET request: *.Using jQuery:
$.get("http://someurl/status/?messageid=597574445", function(data, status){
console.log(data, status);
});
For POST request: 1. Using jQuery $.ajax:
var url= "http://someurl/",
api_key = "6136-bc16-49fb-bacb-802358",
token1 = "Just for test",
result;
$.ajax({
url: url,
type: "POST",
data: {
api_key: api_key,
token1: token1
},
}).done(function(result) {
console.log("done successfuly", result);
}).fail(function(error) {
console.log(error.responseText, error);
});
Using jQuery, append and submit
var merchantId = "AA86E",
token = "4107120133142729",
url = "https://payment.com/Index";
var form = `<form id="send-by-post" method="post" action="${url}">
<input id="token" type="hidden" name="token" value="${merchantId}"/>
<input id="merchantId" name="merchantId" type="hidden" value="${token}"/>
<button type="submit" >Pay</button>
</div>
</form> `;
$('body').append(form);
$("#send-by-post").submit();//Or $(form).appendTo("body").submit();
var api_key = "73736-bc16-49fb-bacb-643e58",
recipient = "095552565",
token1 = "4458",
url = 'http://smspanel.com/send/';
var form = `<form id="send-by-post" method="post" action="${url}">
<input id="api_key" type="hidden" name="api_key" value="${api_key}"/>
<input id="recipient" type="hidden" name="recipient" value="${recipient}"/>
<input id="token1" name="token1" type="hidden" value="${token1}"/>
<button type="submit" >Send</button>
</div>
</form>`;
document.querySelector("body").insertAdjacentHTML('beforeend',form);
document.querySelector("#send-by-post").submit();
Or even using ASP.Net:
var url = "https://Payment.com/index"; Response.Clear(); var sb = new System.Text.StringBuilder();
sb.Append(""); sb.AppendFormat(""); sb.AppendFormat("", url); sb.AppendFormat("", "C668"); sb.AppendFormat("", "22720281459"); sb.Append(""); sb.Append(""); sb.Append(""); Response.Write(sb.ToString()); Response.End();
(Note: Since I have backtick character (`) in my code the code format ruined, I have no idea how to correct it)
One situation that is a little different is when developing a CodeIgniter application. CodeIgniter seems to use the shorttags whenever PHP is being used in a template/view, otherwise with models and controllers it always uses the long tags. It's not a hard and fast rule in the framework, but for the most part the framework and a lot of the source from other uses follows this convention.
My two cents? If you never plan on running the code somewhere else, then use them if you want. I'd rather not have to do a massive search and replace when I realize it was a dumb idea.
Hello If I understood it right you are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You need to do something different when you want to do a cross-domain request. A tutorial about how to achieve that is Using CORS.
When you are using postman they are not restricted by this policy. Quoted from Cross-Origin XMLHttpRequest:
Regular web pages can use the XMLHttpRequest object to send and receive data from remote servers, but they're limited by the same origin policy. Extensions aren't so limited. An extension can talk to remote servers outside of its origin, as long as it first requests cross-origin permissions.
I suspect it's already mentioned in some of the answers, but I'll slightly modify this to have complete working answer (easier to find and use).
Go to: https://nodejs.org/en/download/. Install nodejs.
Install http-server by running command from command prompt npm install -g http-server
.
Change into your working directory, where index.html
/yoursome.html
resides.
Start your http server by running command http-server -c-1
Open web browser to http://localhost:8080
or http://localhost:8080/yoursome.html
- depending on your html filename.
Sometimes you want to change the capitalization of a lot of file names on a case insensitive filesystem (e.g. on OS X or Windows). Doing git mv
commands will tire quickly. To make things a bit easier this is what I do:
git add . -A
to remove all files.git add .
. Git should see that the files are renamed.Now you can make a commit saying you have changed the file name capitalization.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

android:gravity="center|left"
android:orientation="vertical">
Your views go here...
</LinearLayout>
</ScrollView>
I also had the similar problem while registering myinfo.dll file in windows 7. Following work for me: Create a short cut on your desktop C:\Windows\System32\regsvr32.exe c:\windows\system32\myinfo.dll right click on the short cut just created and select as Run as administrator.
This worked perfectly for me:
sudo rm -rf /Library/Java/JavaVirtualMachines
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
Let me make a recap.
When you build a view containing object of different owners, those other owners have to grant "with grant option" to the owner of the view. So, the view owner can grant to other users or schemas....
Example: User_a is the owner of a table called mine_a User_b is the owner of a table called yours_b
Let's say user_b wants to create a view with a join of mine_a and yours_b
For the view to work fine, user_a has to give "grant select on mine_a to user_b with grant option"
Then user_b can grant select on that view to everybody.
You can use
if (array == null || array.Length == 0)
OR
if (!(array != null && array.Length != 0))
NOTE!!!!! To insure that c# will implement the short circuit correctly; you have to compare that the object with NULL before you go to the children compare of the object.
C# 7.0 and above
if(!(array?.Length != 0))
Another idea:
Place all your parameters in a properties file (one parameter = one property in this file), then in your main method, load this file (using Properties.load(*fileInputStream*)
).
So if you want to modify one argument, you will just need to edit your args.properties file, and launch your application without more steps to do...
Of course, this is only for development purposes, but can be really helpfull if you have to change your arguments often...
(this is to add to the chosen answer)
Make sure the iframe
is loaded before you
contentWindow.document
Otherwise, your getElementById
will be null
.
PS: Can't comment, still low reputation to comment, but this is a follow-up on the chosen answer as I've spent some good debugging time trying to figure out I should force the iframe
load before selecting the inner-iframe element.
you can get the index via grep
and colnames
:
grep("B", colnames(df))
[1] 2
or use
grep("^B$", colnames(df))
[1] 2
to only get the columns called "B" without those who contain a B e.g. "ABC".
In this case you could use basename assuming you have the same suffix on the files you want to remove.
Example:
basename -s .rtf "some string.rtf"
This will return "some string"
If you don't know the suffix, and want it to remove everything after and including the last dot:
f=file.whateverthisis
basename "${f%.*}"
outputs "file"
% means chop, . is what you are chopping, * is wildcard
The preceding 0 is used to indicate a number in base 2, 8, or 16.
In my opinion, 0x was chosen to indicate hex because 'x' sounds like hex.
Just my opinion, but I think it makes sense.
Good Day!
Try this:
<a onclick='$("#notification").fadeOut(300, function() { $(this).remove(); });' class="notificationClose "><img src="close.png"/></a>
I think your double quotes around the onclick
were making it not work. :)
EDIT: As pointed out below, inline javascript is evil and you should probably take this out of the onclick
and move it to jQuery's click()
event handler. That is how the cool kids are doing it nowadays.
