Quote taken from Data Structures and Algorithms with JavaScript
The Good Parts (O’Reilly, p. 64). Crockford extends the JavaScript array object with a function that sets the number of rows and columns and sets each value to a value passed to the function. Here is his definition:
Array.matrix = function(numrows, numcols, initial) {
var arr = [];
for (var i = 0; i < numrows; ++i) {
var columns = [];
for (var j = 0; j < numcols; ++j) {
columns[j] = initial;
}
arr[i] = columns;
}
return arr;
}
Here is some code to test the definition:
var nums = Array.matrix(5,5,0);
print(nums[1][1]); // displays 0
var names = Array.matrix(3,3,"");
names[1][2] = "Joe";
print(names[1][2]); // display "Joe"
We can also create a two-dimensional array and initialize it to a set of values in one line:
var grades = [[89, 77, 78],[76, 82, 81],[91, 94, 89]];
print(grades[2][2]); // displays 89
The error message suggests this is not a supported feature in the query language. But you can save a DataFrame in any format as usual through the RDD interface (df.rdd.saveAsTextFile
). Or you can check out https://github.com/databricks/spark-csv.
You can always use the stl:
auto min_value = *std::min_element(v.begin(),v.end());
I use the following format and works well.
robocopy \\SourceServer\Path \\TargetServer\Path filename.txt
to copy everything you can replace filename.txt
with *.*
and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html
no_of_lines = 5
lines = ""
for i in xrange(5):
lines+=input()+"\n"
a=raw_input("if u want to continue (Y/n)")
""
if(a=='y'):
continue
else:
break
print lines
When you look up your php-fpm.conf
example location:
cat /usr/src/php/sapi/fpm/php-fpm.conf
you will see, that you need to configure the PHP FastCGI Process Manager to actually use Unix sockets. Per default, the listen
directive` is set up to listen on a TCP socket on one port. If there's no Unix socket defined, you won't find a Unix socket file.
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all IPv4 addresses on a
; specific port;
; '[::]:port' - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000
Following solution can be pretty useful in the usual login / main activity scenario or implementing a blocking screen.
To minimize the app rather than going back to previous activity, you can override onBackPressed()
like this:
@Override
public void onBackPressed() {
moveTaskToBack(true);
}
moveTaskToBack(boolean nonRoot)
leaves your back stack as it is, just puts your task (all activities) in background. Same as if user pressed Home button.
Parameter boolean nonRoot
- If false then this only works if the activity is the root of a task; if true it will work for any activity in a task.
It probably is the # sign like tho others have mentioned because this appears to work just fine.

i used Bill Paetzke
answer to print a div contain images but it didn't work with google chrome
i just needed to add this line myWindow.onload=function(){
to make it work and here is the full code
<html>
<head>
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js"> </script>
<script type="text/javascript">
function PrintElem(elem) {
Popup($(elem).html());
}
function Popup(data) {
var myWindow = window.open('', 'my div', 'height=400,width=600');
myWindow.document.write('<html><head><title>my div</title>');
/*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
myWindow.document.write('</head><body >');
myWindow.document.write(data);
myWindow.document.write('</body></html>');
myWindow.document.close(); // necessary for IE >= 10
myWindow.onload=function(){ // necessary if the div contain images
myWindow.focus(); // necessary for IE >= 10
myWindow.print();
myWindow.close();
};
}
</script>
</head>
<body>
<div id="myDiv">
This will be printed.
<img src="image.jpg"/>
</div>
<div>
This will not be printed.
</div>
<div id="anotherDiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintElem('#myDiv')" />
</body>
</html>
also if someone just need to print a div with id he doesn't need to load jquery
here is pure javascript code to do this
<html>
<head>
<script type="text/javascript">
function PrintDiv(id) {
var data=document.getElementById(id).innerHTML;
var myWindow = window.open('', 'my div', 'height=400,width=600');
myWindow.document.write('<html><head><title>my div</title>');
/*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
myWindow.document.write('</head><body >');
myWindow.document.write(data);
myWindow.document.write('</body></html>');
myWindow.document.close(); // necessary for IE >= 10
myWindow.onload=function(){ // necessary if the div contain images
myWindow.focus(); // necessary for IE >= 10
myWindow.print();
myWindow.close();
};
}
</script>
</head>
<body>
<div id="myDiv">
This will be printed.
<img src="image.jpg"/>
</div>
<div>
This will not be printed.
</div>
<div id="anotherDiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintDiv('myDiv')" />
</body>
</html>
i hope this can help someone
Your issue is in PHPMyAdmin itself. Some versions do not display the value of bit columns, even though you did set it correctly.
use the scan method e.g.
curl -XGET 'localhost:9200/_search?search_type=scan&scroll=10m&size=50' -d '
{
"query" : {
"match_all" : {}
}
}
see here
My solution:
UserPrincipal user = UserPrincipal.FindByIdentity(new PrincipalContext(ContextType.Domain, myDomain), IdentityType.SamAccountName, myUser);
List<string> UserADGroups = new List<string>();
foreach (GroupPrincipal group in user.GetGroups())
{
UserADGroups.Add(group.ToString());
}

If tomcat did not start up yet , you can use the command \bin\cataline version
to check which JVM will the tomcat use when you start tomcat using bin\startup
In fact ,\bin\cataline version
just call the main class of org.apache.catalina.util.ServerInfo
, which is located inside the \lib\catalina.jar
. The org.apache.catalina.util.ServerInfo
gets the JVM Version and JVM Vendor by the following commands:
System.out.println("JVM Version: " +System.getProperty("java.runtime.version"));
System.out.println("JVM Vendor: " +System.getProperty("java.vm.vendor"));
So , if the tomcat is running , you can create a JSP page that call org.apache.catalina.util.ServerInfo
or just simply call the above System.getProperty()
to get the JVM Version and Vendor . Deploy this JSP to the running tomcat instance and browse to it to see the result.
Alternatively, you should know which port is the running tomcat instance using . So , you can use the OS command to find which process is listening to this port. For example in the window , you can use the command netstat -aon
to find out the process ID of a process that is listening to a particular port . Then go to the window task manager to check the full file path of this process ID belongs to. .The java version can then be determined from that file path.
$.getJSon expects a callback functions either you pass it to the callback function or in callback function assign it to global variale.
var globalJsonVar;
$.getJSON("http://127.0.0.1:8080/horizon-update", function(json){
//do some thing with json or assign global variable to incoming json.
globalJsonVar=json;
});
IMO best is to call the callback function. which is nicer to eyes, readability aspects.
$.getJSON("http://127.0.0.1:8080/horizon-update", callbackFuncWithData);
function callbackFuncWithData(data)
{
// do some thing with data
}
To create a property class please select your package where you wants to create your property file.
Right click on the package and select other. Now select File and type your file name with (.properties) suffix. For example: db.properties. Than click finish. Now you can write your code inside this property file.
A similar option in Sublime Text is the built in Edit->Line->Reindent
. You can put this code in Preferences -> Key Bindings User
:
{ "keys": ["alt+shift+f"], "command": "reindent"}
I use alt+shift+f because I'm a Netbeans user.
To format your code, select all by pressing ctrl+a and "your key combination". Excuse me for my bad english.
Or if you don't want to select all before formatting, add an argument to the command instead:
{ "keys": ["alt+shift+f"], "command": "reindent", "args": {"single_line": false} }
(as per comment by @Supr below)
override func prepareForSegue(segue: UIStoryboardSegue?, sender: AnyObject?) {
if(segue!.identifier){
var name = segue!.identifier;
if (name.compare("Load View") == 0){
}
}
}
You can't compare the the identifier with == you have to use the compare() method
I found out today the keypress event is not fired when hitting the Enter key, so you might want to switch to keydown() or keyup() instead.
My test script:
$('.module input').keydown(function (e) {
var keyCode = e.which;
console.log("keydown ("+keyCode+")")
if (keyCode == 13) {
console.log("enter");
return false;
}
});
$('.module input').keyup(function (e) {
var keyCode = e.which;
console.log("keyup ("+keyCode+")")
if (keyCode == 13) {
console.log("enter");
return false;
}
});
$('.module input').keypress(function (e) {
var keyCode = e.which;
console.log("keypress ("+keyCode+")");
if (keyCode == 13) {
console.log("Enter");
return false;
}
});
The output in the console when typing "A Enter B" on the keyboard:
keydown (65)
keypress (97)
keyup (65)
keydown (13)
enter
keyup (13)
enter
keydown (66)
keypress (98)
keyup (66)
You see in the second sequence the 'keypress' is missing, but keydown and keyup register code '13' as being pressed/released. As per jQuery documentation on the function keypress():
Note: as the keypress event isn't covered by any official specification, the actual behavior encountered when using it may differ across browsers, browser versions, and platforms.
Tested on IE11 and FF61 on Server 2012 R2
I usually take a look at the data first or just try to import it and do data.head(), if you see that the columns are separated with \t then you should specify sep="\t"
otherwise, sep = " "
.

Instant
and LocalDateTime
are two entirely different animals: One represents a moment, the other does not.
Instant
represents a moment, a specific point in the timeline.LocalDateTime
represents a date and a time-of-day. But lacking a time zone or offset-from-UTC, this class cannot represent a moment. It represents potential moments along a range of about 26 to 27 hours, the range of all time zones around the globe. A LocalDateTime
value is inherently ambiguous.
LocalDateTime
is rather date/clock representation including time-zones for humans.
Your statement is incorrect: A LocalDateTime
has no time zone. Having no time zone is the entire point of that class.
To quote that class’ doc:
This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.
So Local…
means “not zoned, no offset”.
Instant
An Instant
is a moment on the timeline in UTC, a count of nanoseconds since the epoch of the first moment of 1970 UTC (basically, see class doc for nitty-gritty details). Since most of your business logic, data storage, and data exchange should be in UTC, this is a handy class to be used often.
Instant instant = Instant.now() ; // Capture the current moment in UTC.
OffsetDateTime
The class OffsetDateTime
class represents a moment as a date and time with a context of some number of hours-minutes-seconds ahead of, or behind, UTC. The amount of offset, the number of hours-minutes-seconds, is represented by the ZoneOffset
class.
If the number of hours-minutes-seconds is zero, an OffsetDateTime
represents a moment in UTC the same as an Instant
.
ZoneOffset
The ZoneOffset
class represents an offset-from-UTC, a number of hours-minutes-seconds ahead of UTC or behind UTC.
A ZoneOffset
is merely a number of hours-minutes-seconds, nothing more. A zone is much more, having a name and a history of changes to offset. So using a zone is always preferable to using a mere offset.
ZoneId
A time zone is represented by the ZoneId
class.
A new day dawns earlier in Paris than in Montréal, for example. So we need to move the clock’s hands to better reflect noon (when the Sun is directly overhead) for a given region. The further away eastward/westward from the UTC line in west Europe/Africa the larger the offset.
A time zone is a set of rules for handling adjustments and anomalies as practiced by a local community or region. The most common anomaly is the all-too-popular lunacy known as Daylight Saving Time (DST).
A time zone has the history of past rules, present rules, and rules confirmed for the near future.
These rules change more often than you might expect. Be sure to keep your date-time library's rules, usually a copy of the 'tz' database, up to date. Keeping up-to-date is easier than ever now in Java 8 with Oracle releasing a Timezone Updater Tool.
Specify a proper time zone name in the format of Continent/Region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 2-4 letter abbreviation such as EST
or IST
as they are not true time zones, not standardized, and not even unique(!).
Time Zone = Offset + Rules of Adjustments
ZoneId z = ZoneId.of( “Africa/Tunis” ) ;
ZonedDateTime
Think of ZonedDateTime
conceptually as an Instant
with an assigned ZoneId
.
ZonedDateTime = ( Instant + ZoneId )
To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone):
ZonedDateTime zdt = ZonedDateTime.now( z ) ; // Pass a `ZoneId` object such as `ZoneId.of( "Europe/Paris" )`.
Nearly all of your backend, database, business logic, data persistence, data exchange should all be in UTC. But for presentation to users you need to adjust into a time zone expected by the user. This is the purpose of the ZonedDateTime
class and the formatter classes used to generate String representations of those date-time values.
ZonedDateTime zdt = instant.atZone( z ) ;
String output = zdt.toString() ; // Standard ISO 8601 format.
You can generate text in localized format using DateTimeFormatter
.
DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL ).withLocale( Locale.CANADA_FRENCH ) ;
String outputFormatted = zdt.format( f ) ;

LocalDate
, LocalTime
, LocalDateTime
The "local" date time classes, LocalDateTime
, LocalDate
, LocalTime
, are a different kind of critter. The are not tied to any one locality or time zone. They are not tied to the timeline. They have no real meaning until you apply them to a locality to find a point on the timeline.
The word “Local” in these class names may be counter-intuitive to the uninitiated. The word means any locality, or every locality, but not a particular locality.
So for business apps, the "Local" types are not often used as they represent just the general idea of a possible date or time not a specific moment on the timeline. Business apps tend to care about the exact moment an invoice arrived, a product shipped for transport, an employee was hired, or the taxi left the garage. So business app developers use Instant
and ZonedDateTime
classes most commonly.
So when would we use LocalDateTime
? In three situations:
Notice that none of these three cases involve a single certain specific point on the timeline, none of these are a moment.
Sometimes we want to represent a certain time-of-day on a certain date, but want to apply that into multiple localities across time zones.
For example, "Christmas starts at midnight on the 25th of December 2015" is a LocalDateTime
. Midnight strikes at different moments in Paris than in Montréal, and different again in Seattle and in Auckland.
LocalDate ld = LocalDate.of( 2018 , Month.DECEMBER , 25 ) ;
LocalTime lt = LocalTime.MIN ; // 00:00:00
LocalDateTime ldt = LocalDateTime.of( ld , lt ) ; // Christmas morning anywhere.
Another example, "Acme Company has a policy that lunchtime starts at 12:30 PM at each of its factories worldwide" is a LocalTime
. To have real meaning you need to apply it to the timeline to figure the moment of 12:30 at the Stuttgart factory or 12:30 at the Rabat factory or 12:30 at the Sydney factory.
Another situation to use LocalDateTime
is for booking future events (ex: Dentist appointments). These appointments may be far enough out in the future that you risk politicians redefining the time zone. Politicians often give little forewarning, or even no warning at all. If you mean "3 PM next January 23rd" regardless of how the politicians may play with the clock, then you cannot record a moment – that would see 3 PM turn into 2 PM or 4 PM if that region adopted or dropped Daylight Saving Time, for example.
For appointments, store a LocalDateTime
and a ZoneId
, kept separately. Later, when generating a schedule, on-the-fly determine a moment by calling LocalDateTime::atZone( ZoneId )
to generate a ZonedDateTime
object.
ZonedDateTime zdt = ldt.atZone( z ) ; // Given a date, a time-of-day, and a time zone, determine a moment, a point on the timeline.
If needed, you can adjust to UTC. Extract an Instant
from the ZonedDateTime
.
Instant instant = zdt.toInstant() ; // Adjust from some zone to UTC. Same moment, same point on the timeline, different wall-clock time.
Some people might use LocalDateTime
in a situation where the time zone or offset is unknown.
I consider this case inappropriate and unwise. If a zone or offset is intended but undetermined, you have bad data. That would be like storing a price of a product without knowing the intended currency (dollars, pounds, euros, etc.). Not a good idea.
For completeness, here is a table of all the possible date-time types, both modern and legacy in Java, as well as those defined by the SQL standard. This might help to place the Instant
& LocalDateTime
classes in a larger context.
Notice the odd choices made by the Java team in designing JDBC 4.2. They chose to support all the java.time times… except for the two most commonly used classes: Instant
& ZonedDateTime
.
But not to worry. We can easily convert back and forth.
Converting Instant
.
// Storing
OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC ) ;
myPreparedStatement.setObject( … , odt ) ;
// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
Instant instant = odt.toInstant() ;
Converting ZonedDateTime
.
// Storing
OffsetDateTime odt = zdt.toOffsetDateTime() ;
myPreparedStatement.setObject( … , odt ) ;
// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
ZoneId z = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = odt.atZone( z ) ;
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.

Here's a slightly simpler implementation without those bugs:
public class MyTreeNode<T>{
private T data = null;
private List<MyTreeNode> children = new ArrayList<>();
private MyTreeNode parent = null;
public MyTreeNode(T data) {
this.data = data;
}
public void addChild(MyTreeNode child) {
child.setParent(this);
this.children.add(child);
}
public void addChild(T data) {
MyTreeNode<T> newChild = new MyTreeNode<>(data);
this.addChild(newChild);
}
public void addChildren(List<MyTreeNode> children) {
for(MyTreeNode t : children) {
t.setParent(this);
}
this.children.addAll(children);
}
public List<MyTreeNode> getChildren() {
return children;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
private void setParent(MyTreeNode parent) {
this.parent = parent;
}
public MyTreeNode getParent() {
return parent;
}
}
Some examples:
MyTreeNode<String> root = new MyTreeNode<>("Root");
MyTreeNode<String> child1 = new MyTreeNode<>("Child1");
child1.addChild("Grandchild1");
child1.addChild("Grandchild2");
MyTreeNode<String> child2 = new MyTreeNode<>("Child2");
child2.addChild("Grandchild3");
root.addChild(child1);
root.addChild(child2);
root.addChild("Child3");
root.addChildren(Arrays.asList(
new MyTreeNode<>("Child4"),
new MyTreeNode<>("Child5"),
new MyTreeNode<>("Child6")
));
for(MyTreeNode node : root.getChildren()) {
System.out.println(node.getData());
}
The UUID is used for uniquely identifying information. It identifies a particular service provided by a Bluetooth device. The standard defines a basic BASE_UUID: 00000000-0000-1000-8000-00805F9B34FB
.
Devices such as healthcare sensors can provide a service, substituting the first eight digits with a predefined code. For example, a device that offers an RFCOMM connection uses the short code: 0x0003
So, an Android phone can connect to a device and then use the Service Discovery Protocol (SDP) to find out what services it provides (UUID).
In many cases, you don't need to use these fixed UUIDs. In the case your are creating a chat application, for example, one Android phone interacts with another Android phone that uses the same application and hence the same UUID.
So, you can set an arbitrary UUID for your application using, for example, one of the many random UUID generators on the web (for example).
changing the complie SDk version to API level 21 fixed it for me. then i ran into others issues of deploying the app to my device. i changed the minimun API level to target to what i want and that fixed it.
incase someone is experiencing this again.
FragmentActivity
is part of the support library, while Activity
is the framework's default class. They are functionally equivalent.
You should always use FragmentActivity
and android.support.v4.app.Fragment
instead of the platform default Activity
and android.app.Fragment
classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.
You shouldn't be closing the serial port in Python between writing and reading. There is a chance that the port is still closed when the Arduino responds, in which case the data will be lost.
while running:
# Serial write section
setTempCar1 = 63
setTempCar2 = 37
setTemp1 = str(setTempCar1)
setTemp2 = str(setTempCar2)
print ("Python value sent: ")
print (setTemp1)
ard.write(setTemp1)
time.sleep(6) # with the port open, the response will be buffered
# so wait a bit longer for response here
# Serial read section
msg = ard.read(ard.inWaiting()) # read everything in the input buffer
print ("Message from arduino: ")
print (msg)
The Python Serial.read
function only returns a single byte by default, so you need to either call it in a loop or wait for the data to be transmitted and then read the whole buffer.
On the Arduino side, you should consider what happens in your loop
function when no data is available.
void loop()
{
// serial read section
while (Serial.available()) // this will be skipped if no data present, leading to
// the code sitting in the delay function below
{
delay(30); //delay to allow buffer to fill
if (Serial.available() >0)
{
char c = Serial.read(); //gets one byte from serial buffer
readString += c; //makes the string readString
}
}
Instead, wait at the start of the loop
function until data arrives:
void loop()
{
while (!Serial.available()) {} // wait for data to arrive
// serial read section
while (Serial.available())
{
// continue as before
EDIT 2
Here's what I get when interfacing with your Arduino app from Python:
>>> import serial
>>> s = serial.Serial('/dev/tty.usbmodem1411', 9600, timeout=5)
>>> s.write('2')
1
>>> s.readline()
'Arduino received: 2\r\n'
So that seems to be working fine.
In testing your Python script, it seems the problem is that the Arduino resets when you open the serial port (at least my Uno does), so you need to wait a few seconds for it to start up. You are also only reading a single line for the response, so I've fixed that in the code below also:
#!/usr/bin/python
import serial
import syslog
import time
#The following line is for serial over GPIO
port = '/dev/tty.usbmodem1411' # note I'm using Mac OS-X
ard = serial.Serial(port,9600,timeout=5)
time.sleep(2) # wait for Arduino
i = 0
while (i < 4):
# Serial write section
setTempCar1 = 63
setTempCar2 = 37
ard.flush()
setTemp1 = str(setTempCar1)
setTemp2 = str(setTempCar2)
print ("Python value sent: ")
print (setTemp1)
ard.write(setTemp1)
time.sleep(1) # I shortened this to match the new value in your Arduino code
# Serial read section
msg = ard.read(ard.inWaiting()) # read all characters in buffer
print ("Message from arduino: ")
print (msg)
i = i + 1
else:
print "Exiting"
exit()
Here's the output of the above now:
$ python ardser.py

Otherwise, the value passed is a new slice of type []T

I had a problem where the images would not show and it wasn't the relative path. I even hard coded the actual path and the image still did not show. I had changed my webserver to run on port 8080 and neither
<img src="c:/public/images/<?php echo $image->filename; ?>" width="100" />
<img src="c:/public/images/mypic.jpg" width="100" />
would not work.
<img src="../../images/<?php echo $photo->filename; ?>" width="100" />
Did not work either. This did work :
<img src="http://localhost:8080/public/images/<?php echo $image->filename; ?>" width="100" />
If you want to set custom content-type for formData item:

};
var fdata = new FormData();
fdata.append('personInfo', {

fdata.append('image', {

Let's change tütü's code

disableEnableControls(enable, (ViewGroup)child);
} else {
child.setEnabled(enable);
}
}
}
I think, there is no point in just making viewgroup disable. If you want to do it, there is another way I have used for exactly the same purpose. Create view as a sibling of your groupview :
<View
android:visibility="gone"
android:id="@+id/reservation_second_screen"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:background="#66ffffff"
android:clickable="false" />
and at run-time, make it visible. Note: your groupview's parent layout should be either relative or frame layout. Hope this will help.

The :before
pseudo element isn't needed for the clearfix hack itself.
It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.
display:table
is being used because display:block
doesn't do the trick. Using display:block
margins will collapse even with a :before
element.
There is one caveat: if vertical-align:baseline
is used in table cells with clearfixed <div>
elements, Firefox won't align well. Then you might prefer using display:block
despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

Looks like your depth
variable is unset. This means that the expression [ $depth -eq $zero ]
becomes [ -eq 0 ]
after bash substitutes the values of the variables into the expression. The problem here is that the -eq
operator is incorrectly used as an operator with only one argument (the zero), but it requires two arguments. That is why you get the unary operator error message.
EDIT: As Doktor J mentioned in his comment to this answer, a safe way to avoid problems with unset variables in checks is to enclose the variables in ""
. See his comment for the explanation.
if [ "$depth" -eq "0" ]; then
echo "false";
exit;
fi
An unset variable used with the [
command appears empty to bash. You can verify this using the below tests which all evaluate to true
because xyz
is either empty or unset:
if [ -z ] ; then echo "true"; else echo "false"; fi
xyz=""; if [ -z "$xyz" ] ; then echo "true"; else echo "false"; fi
unset xyz; if [ -z "$xyz" ] ; then echo "true"; else echo "false"; fi
I should like to take a step back and a modern look at this 10 years old question. The classes mentioned, Date
and XMLGregorianCalendar
, are old now. I challenge the use of them and offer alternatives.
Date
was always poorly designed and is more than 20 years old. This is simple: don’t use it.XMLGregorianCalendar
is old too and has an old-fashioned design. As I understand it, it was used for producing dates and times in XML format for XML documents. Like 2009-05-07T19:05:45.678+02:00
or 2009-05-07T17:05:45.678Z
. These formats agree well enough with ISO 8601 that the classes of java.time, the modern Java date and time API, can produce them, which we prefer.For many (most?) purposes the modern replacement for a Date
will be an Instant
. An Instant
is a point in time (just as a Date
is).
Instant yourInstant = // ...
System.out.println(yourInstant);
An example output from this snippet:
2009-05-07T17:05:45.678Z
It’s the same as the latter of my example XMLGregorianCalendar
strings above. As most of you know, it comes from Instant.toString
being implicitly called by System.out.println
. With java.time, in many cases we don’t need the conversions that in the old days we made between Date
, Calendar
, XMLGregorianCalendar
and other classes (in some cases we do need conversions, though, I am showing you a couple in the next section).
Neither a Date
nor in Instant
has got a time zone nor a UTC offset. The previously accepted and still highest voted answer by Ben Noland uses the JVMs current default time zone for selecting the offset of the XMLGregorianCalendar
. To include an offset in a modern object we use an OffsetDateTime
. For example:
ZoneId zone = ZoneId.of("America/Asuncion");
OffsetDateTime dateTime = yourInstant.atZone(zone).toOffsetDateTime();
System.out.println(dateTime);
2009-05-07T13:05:45.678-04:00
Again this conforms with XML format. If you want to use the current JVM time zone setting again, set zone
to ZoneId.systemDefault()
.
There are more ways to convert Instant
to XMLGregorianCalendar
. I will present a couple, each with its pros and cons. First, just as an XMLGregorianCalendar
produces a string like 2009-05-07T17:05:45.678Z
, it can also be built from such a string:
String dateTimeString = yourInstant.toString();
XMLGregorianCalendar date2
= DatatypeFactory.newInstance().newXMLGregorianCalendar(dateTimeString);
System.out.println(date2);
2009-05-07T17:05:45.678Z
Pro: it’s short and I don’t think it gives any surprises. Con: To me it feels like a waste formatting the instant into a string and parsing it back.
ZonedDateTime dateTime = yourInstant.atZone(zone);
GregorianCalendar c = GregorianCalendar.from(dateTime);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);
System.out.println(date2);
2009-05-07T13:05:45.678-04:00
Pro: It’s the official conversion. Controlling the offset comes naturally. Con: It goes through more steps and is therefore longer.
If you got an old-fashioned Date
object from a legacy API that you cannot afford to change just now, convert it to Instant
:
Instant i = yourDate.toInstant();
System.out.println(i);
Output is the same as before:
2009-05-07T17:05:45.678Z
If you want to control the offset, convert further to an OffsetDateTime
in the same way as above.
If you’ve got an old-fashioned Date
and absolutely need an old-fashioned XMLGregorianCalendar
, just use the answer by Ben Noland.

Generally, it's considered a bad practice to style standard form controls because the output looks so different on each browser. See: http://www.456bereastreet.com/lab/styling-form-controls-revisited/select-single/ for some rendered examples.
That being said, I've had some luck making the background color an RGBA value:
<!DOCTYPE html>
<html>
<head>
<style>
body {
background: #d00;
}
select {
background: rgba(255,255,255,0.1) url('http://www.google.com/images/srpr/nav_logo6g.png') repeat-x 0 0;
padding:4px;
line-height: 21px;
border: 1px solid #fff;
}
</style>
</head>
<body>
<select>
<option>Foo</option>
<option>Bar</option>
<option>Something longer</option>
</body>
</html>
Google Chrome still renders a gradient on top of the background image in the color that you pass to rgba(r,g,b,0.1) but choosing a color that compliments your image and making the alpha 0.1 reduces the effect of this.

If you scale 1600x900
to 1280x720
you have
scale_x = 1280.0/1600
scale_y = 720.0/900
Then you can use it to find button size, and button position
button_width = 300 * scale_x
button_height = 300 * scale_y
button_x = 1440 * scale_x
button_y = 860 * scale_y
If you scale 1280x720
to 1600x900
you have
scale_x = 1600.0/1280
scale_y = 900.0/720
and rest is the same.
I add .0
to value to make float
- otherwise scale_x
, scale_y
will be rounded to integer

varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.
Python is case sensitive and needs proper indentation. You need to use lowercase "if", indent your conditions properly and the code has a bug. proceed

It's an ordinary Python list. The exception that you would catch for this is IndexError, but you're better off just checking the length instead.

output, in order to make the example minimal:
dput(droplevels(head(mydata)))
you can use getline from a file using this code. this code will take a whole line from the file. and then you can use a while loop to go all lines while (ins);

, without is:
var arr = str.split( /(?<=^(?:.{3})+)/ ) // [ 'abc', 'def', 'ghi', 'jkl' ] // I don't know why is not [ 'abc', 'def', 'ghi', 'jkl' , '' ], comment?
var replaced = str.replace( /(?<=^(.{3})+)/g, ' || ') // 'abc || def || ghi || jkl || '
ignoring group /(?:
...)/
is no need in .replace
but in .split
is adding groups to arr:
var arr = str.split( /(?<=^(.{3})+)(?!$)/ ) // [ 'abc', 'abc', 'def', 'abc', 'ghi', 'abc', 'jkl' ]
Best practice: one form per product is definitely the way to go.
Benefits:
In your specific situation
If you only ever intend to have one form element, in this case a submit
button, one form for all should work just fine.
My recommendation Do one form per product, and change your markup to something like:
<form method="post" action="">
<input type="hidden" name="product_id" value="123">
<button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>
This will give you a much cleaner and usable POST
. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).
Note: There's no technical benefit to using
<button>
vs.<input>
, but as a programmer I find it cooler to work withaction=='add_to_cart'
thanaction=='Add to Cart'
. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.
var arr = [ {"id":"10", "class": "child-of-9"}, {"id":"11", "class": "child-of-10"}];
for (var i = 0; i < arr.length; i++){
document.write("<br><br>array index: " + i);
var obj = arr[i];
for (var key in obj){
var value = obj[key];
document.write("<br> - " + key + ": " + value);
}
}

note: the for-in method is cool for simple objects. Not very smart to use with DOM object.
Don't use wait()
, use either android.os.SystemClock.sleep(1000);
or Thread.sleep(1000);
.
The main difference between them is that Thread.sleep()
can be interrupted early -- you'll be told, but it's still not the full second. The android.os
call will not wake early.

I believe it would be best to use a self recursive method. That way it goes as deep as is needed. This will delete the key value pair if the value is nil or an empty Hash.
class Hash
def compact
delete_if {|k,v| v.is_a?(Hash) ? v.compact.empty? : v.nil? }
end
end
Then using it will look like this:
x = {:a=>{:b=>2, :c=>3}, :d=>nil, :e=>{:f=>nil}, :g=>{}}
# => {:a=>{:b=>2, :c=>3}, :d=>nil, :e=>{:f=>nil}, :g=>{}}
x.compact
# => {:a=>{:b=>2, :c=>3}}
To keep empty hashes you can simplify this to.
class Hash
def compact
delete_if {|k,v| v.compact if v.is_a?(Hash); v.nil? }
end
end
If you have it in a string, you can use .split()
to separate them.
>>> for string in ('Mike 18', 'Kevin 35', 'Angel 56'):
... l = string.split()
... print repr(l[0]), repr(int(l[1]))
...
'Mike' 18
'Kevin' 35
'Angel' 56
>>>
You are using the wrong iteration counter, replace inp.charAt(i)
with inp.charAt(j)
.
You can achieve this like following :
map<string, int>::iterator it;
for (it = symbolTable.begin(); it != symbolTable.end(); it++)
{
std::cout << it->first // string (key)
<< ':'
<< it->second // string's value
<< std::endl;
}
With C++11 ( and onwards ),
for (auto const& x : symbolTable)
{
std::cout << x.first // string (key)
<< ':'
<< x.second // string's value
<< std::endl;
}
With C++17 ( and onwards ),
for (auto const& [key, val] : symbolTable)
{
std::cout << key // string (key)
<< ':'
<< val // string's value
<< std::endl;
}
Also, there's the handy little "increase indent" and "decrease indent" buttons. If you highlight a block of code and click those buttons the entire block will indent.
On the flip side, I was having an issue with PHPUNIT asserting urls was contained in or equal to a url that was json_encoded -
my expected:
http://localhost/api/v1/admin/logs/testLog.log
would be encoded to:
http:\/\/localhost\/api\/v1\/admin\/logs\/testLog.log
If you need to do a comparison, transforming the url using:
addcslashes($url, '/')
allowed for the proper output during my comparisons.
Had the same issue with Ionic routing.
Simple solution is to use the name of the state - basically state.go(state name)
.state('tab.search', {
url: '/search',
views: {
'tab-search': {
templateUrl: 'templates/search.html',
controller: 'SearchCtrl'
}
}
})
And in controller you can use $state.go('tab.search');
Here s what I suggest without using any other dependency , just node and express, use app.locals, here s an example :
app.get("/", function(req, res) {
var context = req.app.locals.specialContext;
req.app.locals.specialContext = null;
res.render("home.jade", context);
// or if you are using ejs
res.render("home", {context: context});
});
function middleware(req, res, next) {
req.app.locals.specialContext = * your context goes here *
res.redirect("/");
}

Let's make it simple as hell. If you want a single number for the number of dimensions like 2, 3, 4, etc.,
then just use tf.rank()
. But, if you want the exact shape of the tensor then use tensor.get_shape()
with tf.Session() as sess:
arr = tf.random_normal(shape=(10, 32, 32, 128))
a = tf.random_gamma(shape=(3, 3, 1), alpha=0.1)
print(sess.run([tf.rank(arr), tf.rank(a)]))
print(arr.get_shape(), ", ", a.get_shape())
# for tf.rank()
[4, 3]
# for tf.get_shape()
Output: (10, 32, 32, 128) , (3, 3, 1)
I believe this is what you're looking for:
<div>{{ (collection | fitler1:args) + (collection | filter2:args) }}</div>
In Python/Spark we can do:
def quiet_logs( sc ):
logger = sc._jvm.org.apache.log4j
logger.LogManager.getLogger("org"). setLevel( logger.Level.ERROR )
logger.LogManager.getLogger("akka").setLevel( logger.Level.ERROR )
The after defining Sparkcontaxt 'sc' call this function by : quiet_logs( sc )
non of the solutions worked well for me. especially when there are many gaps and set is small. this worked very well for me(in php):
$count = $collection->count($search);
$skip = mt_rand(0, $count - 1);
$result = $collection->find($search)->skip($skip)->limit(1)->getNext();
Unless you have a specific reason to do raw ado.net I would have a look at using an ORM (object relational mapper) like nHibernate or LINQ to SQL. That way you can query the database and retrieve objects to work with which are strongly typed and easier to work with IMHO.
To quote the article below, ""then" takes two arguments, a callback for a success case, and another for the failure case. Both are optional, so you can add a callback for the success or failure case only."
I usually look to this page for any basic promise questions, let me know if I am wrong
Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.
.left {
float: left;
width: 125px;
text-align: right;
margin: 2px 10px;
display: inline;
}
.right {
float: left;
text-align: left;
margin: 2px 10px;
display: inline;
}
Usually this is due to another directive in-between your ng-controller and your input that is creating a new scope. When the select writes out it value, it will write it up to the most recent scope, so it would write it to this scope rather than the parent that is further away.
The best practice is to never bind directly to a variable on the scope in an
ng-model
, this is also known as always including a "dot" in your ngmodel. For a better explanation of this, check out this video from John:
Solution from: https://groups.google.com/forum/#!topic/angular/7Nd_me5YrHU
Try Math.log(x) / Math.log(2)
As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval
:
/*jshint evil:true */
function helloEval(str) {
/*jshint evil:true */
eval(str);
}
Try this...
function Test()
{
var s1 = new StopWatch();
s1.Start();
// Do something.
s1.Stop();
alert( s1.ElapsedMilliseconds );
}
// Create a stopwatch "class."
StopWatch = function()
{
this.StartMilliseconds = 0;
this.ElapsedMilliseconds = 0;
}
StopWatch.prototype.Start = function()
{
this.StartMilliseconds = new Date().getTime();
}
StopWatch.prototype.Stop = function()
{
this.ElapsedMilliseconds = new Date().getTime() - this.StartMilliseconds;
}
Update Angular CLI for a workspace (Local)
npm install --save -dev @angular/cli@latest
Note: Make sure to install the global version using the command with ‘-g’ is if it installed properly.
npm install -g @angular/cli@latest
Run Update command to get a list of all dependencies required to be upgraded
ng update
Next Run update command as below for each individual Angular core package
ng update @angular/cli @angular/core
However, I had to add ‘–force’ and ‘–allow-dirty’ flags command additionally to fix all other pending issues.
ng update @angular/cli @angular/core --allow-dirty --force
You can use the Test-Path
cmd-let. So something like...
if(!(Test-Path [oldLocation]) -and !(Test-Path [newLocation]))
{
Write-Host "$file doesn't exist in both locations."
}
Here is something that might help. Use the root privileges. if you have .bin then simply add the execution permission to the bin file.
chmod a+x jdk*.bin
next step is to run the .bin file which is simply
./jdk*.bin in the location you want to install.
you are done.
A multi-producers and multi-consumers example, verified. It should be easy to modify it to cover other cases, single/multi producers, single/multi consumers.
from multiprocessing import Process, JoinableQueue
import time
import os
q = JoinableQueue()
def producer():
for item in range(30):
time.sleep(2)
q.put(item)
pid = os.getpid()
print(f'producer {pid} done')
def worker():
while True:
item = q.get()
pid = os.getpid()
print(f'pid {pid} Working on {item}')
print(f'pid {pid} Finished {item}')
q.task_done()
for i in range(5):
p = Process(target=worker, daemon=True).start()
# send thirty task requests to the worker
producers = []
for i in range(2):
p = Process(target=producer)
producers.append(p)
p.start()
# make sure producers done
for p in producers:
p.join()
# block until all workers are done
q.join()

It's actually Document Object Model. HTML is used to build the DOM which is an in-memory representation of the page (while closely related to HTML, they are not exactly the same thing). Things like CSS and Javascript interact with the DOM.
I find the following function sufficient:
'
' Round Up to the given number of digits
'
Function RoundUp(x As Double, digits As Integer) As Double
If x = Round(x, digits) Then
RoundUp = x
Else
RoundUp = Round(x + 0.5 / (10 ^ digits), digits)
End If
End Function
In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.
When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.
When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).
A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.
You can use define window.myvar = {}
.
When you want to use it, you can use like window.myvar = 1
Install autoenv either by
$ pip install autoenv
(or)
$ brew install autoenv
And then create .env
file in your virtualenv project folder
$ echo "source bin/activate" > .env
Now everything works fine.
var mySound = NSSound(named:"Morse.aiff")
mySound.play()
"Morse.aiff" is a system sound of OSX, but if you just click on "named" within XCode, you'll be able to view (in the QuickHelp pane) where this function is searching the sounds. It can be in your "Supporting files" folder
I hope you managed to obtain the json data from the json string.
Well I think this will be of help
try {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(urls[0])
.build();
Response responses = null;
try {
responses = client.newCall(request).execute();
} catch (IOException e) {
e.printStackTrace();
}
String jsonData = responses.body().string();
JSONObject Jobject = new JSONObject(jsonData);
JSONArray Jarray = Jobject.getJSONArray("employees");
//define the strings that will temporary store the data
String fname,lname;
//get the length of the json array
int limit = Jarray.length()
//datastore array of size limit
String dataStore[] = new String[limit];
for (int i = 0; i < limit; i++) {
JSONObject object = Jarray.getJSONObject(i);
fname = object.getString("firstName");
lname = object.getString("lastName");
Log.d("JSON DATA", fname + " ## " + lname);
//store the data into the array
dataStore[i] = fname + " ## " + lname;
}
//prove that the data was stored in the array
for (String content ; dataStore ) {
Log.d("ARRAY CONTENT", content);
}
Remember to use AsyncTask or SyncAdapter(IntentService), to prevent getting a NetworkOnMainThreadException
Also import the okhttp library in your build.gradle
compile 'com.squareup.okhttp:okhttp:2.4.0'
The current best solution to this problem (referenced deep in https://github.com/kubernetes/kubernetes/issues/22368 linked in the sibling answer) is to use Deployments, and consider your ConfigMaps to be immutable.
When you want to change your config, create a new ConfigMap with the changes you want to make, and point your deployment at the new ConfigMap. If the new config is broken, the Deployment will refuse to scale down your working ReplicaSet. If the new config works, then your old ReplicaSet will be scaled to 0 replicas and deleted, and new pods will be started with the new config.
Not quite as quick as just editing the ConfigMap in place, but much safer.
Try below structure for applying two color border,
<div class="white">
<div class="grey">
</div>
</div>
.white
{
border: 2px solid white;
}
.grey
{
border: 1px solid grey;
}
I also faced this ? issue. Meanwhile I ran into three cases where it happened:
substr()
I was using substr()
on a UTF8 string which cut UTF8 characters, thus the cut chars could not be displayed correctly. Use mb_substr($utfstring, 0, 10, 'utf-8');
instead. Credits
htmlspecialchars()
Another problem was using htmlspecialchars()
on a UTF8 string. The fix is to use: htmlspecialchars($utfstring, ENT_QUOTES, 'UTF-8');
preg_replace()
Lastly I found out that preg_replace()
can lead to problems with UTF. The code $string = preg_replace('/[^A-Za-z0-9ÄäÜüÖöß]/', ' ', $string);
for example transformed the UTF string "F(×)=2×-3" into "F ? 2? ". The fix is to use mb_ereg_replace()
instead.
I hope this additional information will help to get rid of such problems.
This is common issue and its looking for .cmd
file from your root directory where you installed babel-cli
. Try the below command.
./node_modules/.bin/babel.cmd
Once you are able to see your source code in the command prompt. Your next step is to install one more npm module babel-preset-es2015
.
Follow the below answer to install babel-preset-es2015
and see why babel need this.
UPDATED:
TO NOT HAVE ANY
b
and quotes at first and endHow to convert
bytes
as seen to strings, even in weird situations.
As your code may have unrecognizable characters to 'utf-8'
encoding,
it's better to use just str without any additional parameters:
some_bad_bytes = b'\x02-\xdfI#)'
text = str( some_bad_bytes )[2:-1]
print(text)
Output: \x02-\xdfI
if you add 'utf-8'
parameter, to these specific bytes, you should receive error.
As PYTHON 3 standard says, text
would be in utf-8 now with no concern.

I had same problem. I wanted to edit ENUM values in table structure. Problem was because of rows that was saved before and new ENUM values doesn't contain saved values.
Solution was updating old saved rows in MySql table.
I also have a site that has numerous urls with urlencoded characters. I am finding that many web APIs (including Google webmaster tools and several Drupal modules) trip over urlencoded characters. Many APIs automatically decode urls at some point in their process and then use the result as a URL or HTML. When I find one of these problems, I usually double encode the results (which turns %2f into %252f) for that API. However, this will break other APIs which are not expecting double encoding, so this is not a universal solution.
Personally I am getting rid of as many special characters in my URLs as possible.
Also, I am using id numbers in my URLs which do not depend on urldecoding:
example.com/blog/my-amazing-blog%2fstory/yesterday
becomes:
example.com/blog/12354/my-amazing-blog%2fstory/yesterday
in this case, my code only uses 12354 to look for the article, and the rest of the URL gets ignored by my system (but is still used for SEO.) Also, this number should appear BEFORE the unused URL components. that way, the url will still work, even if the %2f gets decoded incorrectly.
Also, be sure to use canonical tags to ensure that url mistakes don't translate into duplicate content.
In a linux environment the soft link apparently does not work. you must use the physical path. for instance on my machine I have a softlink at /usr/share/tomacat7/lib/servlet-api.jar
and using this as my classpath argument led to a failed compile with the same error. instead I had to use /usr/share/java/tomcat-servlet-api-3.0.jar
which is the file that the soft link pointed to.
You can use the dangerouslySetInnerHTML
property to inject arbitrary HTML:
// Assume from another require()'ed module:_x000D_
var html = '<h1>Hello, world!</h1>'_x000D_
_x000D_
var MyComponent = React.createClass({_x000D_
render: function() {_x000D_
return React.createElement("h1", {dangerouslySetInnerHTML: {__html: html}})_x000D_
}_x000D_
})_x000D_
_x000D_
ReactDOM.render(React.createElement(MyComponent), document.getElementById('app'))
_x000D_
<script src="https://fb.me/react-0.14.3.min.js"></script>_x000D_
<script src="https://fb.me/react-dom-0.14.3.min.js"></script>_x000D_
<div id="app"></div>
_x000D_
You could even componentize this template behavior (untested):
class TemplateComponent extends React.Component {
constructor(props) {
super(props)
this.html = require(props.template)
}
render() {
return <div dangerouslySetInnerHTML={{__html: this.html}}/>
}
}
TemplateComponent.propTypes = {
template: React.PropTypes.string.isRequired
}
// use like
<TemplateComponent template='./template.html'/>
And with this, template.html
(in the same directory) looks something like (again, untested):
// ./template.html
module.exports = '<h1>Hello, world!</h1>'
Correct way described in this answer: https://stackoverflow.com/a/52772444/2519714 Most popular answer at current moment is not totally correct.
This way https://stackoverflow.com/a/24838367/2519714 is not correct in some cases like: sub select has where bindings, then joining table to sub select, then other wheres added to all query. For example query:
select * from (select * from t1 where col1 = ?) join t2 on col1 = col2 and col3 = ? where t2.col4 = ?
To make this query you will write code like:
$subQuery = DB::query()->from('t1')->where('t1.col1', 'val1');
$query = DB::query()->from(DB::raw('('. $subQuery->toSql() . ') AS subquery'))
->mergeBindings($subQuery->getBindings());
$query->join('t2', function(JoinClause $join) {
$join->on('subquery.col1', 't2.col2');
$join->where('t2.col3', 'val3');
})->where('t2.col4', 'val4');
During executing this query, his method $query->getBindings()
will return bindings in incorrect order like ['val3', 'val1', 'val4']
in this case instead correct ['val1', 'val3', 'val4']
for raw sql described above.
One more time correct way to do this:
$subQuery = DB::query()->from('t1')->where('t1.col1', 'val1');
$query = DB::query()->fromSub($subQuery, 'subquery');
$query->join('t2', function(JoinClause $join) {
$join->on('subquery.col1', 't2.col2');
$join->where('t2.col3', 'val3');
})->where('t2.col4', 'val4');
Also bindings will be automatically and correctly merged to new query.
Using some of the above recommendations, the following function and code is working for search a date range:
Set date with the time component set to 00:00:00
public static DateTime GetDateZeroTime(DateTime date)
{
return new DateTime(date.Year, date.Month, date.Day, 0, 0, 0);
}
Usage
var modifieddatebegin = Tools.Utilities.GetDateZeroTime(form.modifieddatebegin);
var modifieddateend = Tools.Utilities.GetDateZeroTime(form.modifieddateend.AddDays(1));
Convert the collection into an array by using function
Object[] toArray(Object[] a)
We use Akka in spoken dialog systems (primetalk). Both internally and externally. In order to simultaneously run a lot of telephony channels on a single cluster node it is obviously necessary to have some multithreading framework. Akka works just perfect. We have previous nightmare with the java-concurrency. And with Akka it is just like a swing — it simply works. Robust and reliable. 24*7, non-stop.
Inside a channel we have real-time stream of events that are processed in parallel. In particular: - lengthy automatic speech recognition — is done with an actor; - audio output producer that mixes a few audio sources (including synthesized speech); - text-to-speech conversion is a separate set of actors shared between channels; - semantic and knowledge processing.
To make interconnections of complex signal processing we use SynapseGrid. It has the benefit of compile-time checking of the DataFlow in the complex actor systems.
You want to do this:
git add -u
git reset HEAD path/to/file
git commit
Be sure and do this from the top level of the repo; add -u
adds changes in the current directory (recursively).
The key line tells git to reset the version of the given path in the index (the staging area for the commit) to the version from HEAD (the currently checked-out commit).
And advance warning of a gotcha for others reading this: add -u
stages all modifications, but doesn't add untracked files. This is the same as what commit -a
does. If you want to add untracked files too, use add .
to recursively add everything.
You can use a single line to add and remove class on a div. Please remove a class first to add a new class.
$('div').on('click',function(){
$('div').removeClass('active').addClass('active');
});
Just in case you're wondering how you can set multiple different sizes in the same textview, but using an absolute size and not a relative one, you can achieve that using AbsoluteSizeSpan
instead of a RelativeSizeSpan
.
Just get the dimension in pixels of the desired text size
int textSize1 = getResources().getDimensionPixelSize(R.dimen.text_size_1);
int textSize2 = getResources().getDimensionPixelSize(R.dimen.text_size_2);
and then create a new AbsoluteSpan
based on the text
String text1 = "Hi";
String text2 = "there";
SpannableString span1 = new SpannableString(text1);
span1.setSpan(new AbsoluteSizeSpan(textSize1), 0, text1.length(), SPAN_INCLUSIVE_INCLUSIVE);
SpannableString span2 = new SpannableString(text2);
span2.setSpan(new AbsoluteSizeSpan(textSize2), 0, text2.length(), SPAN_INCLUSIVE_INCLUSIVE);
// let's put both spans together with a separator and all
CharSequence finalText = TextUtils.concat(span1, " ", span2);

Though I admit that there should be a better way to do that, but this at least avoids iterating and looping through the object and moves it to the C level.
The solution is to define a custom binding inside your Web.Config file and set the security mode to "Transport". Then you just need to use the bindingConfiguration property inside your endpoint definition to point to your custom binding.
Not proud of it, but:
def myMain(key):
def ExecP1():
pass
def ExecP2():
pass
def ExecP3():
pass
def ExecPn():
pass
locals()['Exec' + key]()
I do however recommend that you put those in a module/class whatever, this is truly horrible.
The answer probably depends how critical it is for you to receive support and possible customization for this service.
Google can certainly do this. Look into their XML and Geocoding API's. You should be able to craft an XML message asking Google to return Map coordinates for a given address. If the address is not found (invalid), you will receive an appropriate response. Here's a useful page: http://code.google.com/apis/maps/documentation/services.html#XML_Requests
Note that Google's aim in providing the Maps API is to plot addresses on actual maps. While you can certainly use the data for other purposes, you are at the mercy of Google should one of their maps not exactly correspond to your legal or commercial address validation needs. If you paid for one of the services you mentioned, you would likely be able to receive support should certain addresses not resolve the way you expect them to.
In other words, you get what you pay for ;) . If you have the time, though, why not try implementing a Google-based solution then going from there? The API looks pretty slick, and it's free, after all.
you can give :
select{
position:absolute;
top:50%;
transform: translateY(-50%);
}
and to parent you have to give position:relative. it will work.
sounds like you downloaded the german xampp package instead of the english xampp package (yes, it's another download-link) where the language is set according to the package you loaded. to change the language afterwards, simply edit the config.inc.php
and set:
$cfg['Lang'] = 'en-utf-8';

OP here, I have learned a lot more about node since I first asked this question. Though Dmitry's answer was very helpful, what ultimately did it for me is to install node with the correct permissions.
I highly recommend not installing node using any package managers, but rather to compile it yourself so that it resides in a local directory with normal permissions.
This article provides a very clear step-by-step instruction of how to do so:
The name of the DOM function is actually getElementsByClassName
, not getElementByClassName
, simply because more than one element on the page can have the same class, hence: Elements
.
The return value of this will be a NodeList instance, or a superset of the NodeList
(FF, for instance returns an instance of HTMLCollection
). At any rate: the return value is an array-like object:
var y = document.getElementsByClassName('foo');
var aNode = y[0];
If, for some reason you need the return object as an array, you can do that easily, because of its magic length property:
var arrFromList = Array.prototype.slice.call(y);
//or as per AntonB's comment:
var arrFromList = [].slice.call(y);
As yckart suggested querySelector('.foo')
and querySelectorAll('.foo')
would be preferable, though, as they are, indeed, better supported (93.99% vs 87.24%), according to caniuse.com:
Descending order of price:
homes.sort((x,y) => {return y.price - x.price})
Ascending order of price:
homes.sort((x,y) => {return x.price - y.price})
I created a simple Date struct for times when you need a simple date without worrying about time portion, timezones, local vs. utc, etc.
Date today = Date.Today;
Date yesterday = Date.Today.AddDays(-1);
Date independenceDay = Date.Parse("2013-07-04");
independenceDay.ToLongString(); // "Thursday, July 4, 2013"
independenceDay.ToShortString(); // "7/4/2013"
independenceDay.ToString(); // "7/4/2013"
independenceDay.ToString("s"); // "2013-07-04"
int july = independenceDay.Month; // 7
Try this
<script type="text/javascript">
function AddItem()
{
// Create an Option object
var opt = document.createElement("option");
// Assign text and value to Option object
opt.text = "New Value";
opt.value = "New Value";
// Add an Option object to Drop Down List Box
document.getElementById('<%=DropDownList.ClientID%>').options.add(opt);
}
<script />
The Value will append to the drop down list.
Try this:
<activity
...
android:windowSoftInputMode="stateHidden|adjustResize"

If someone interested in pseudo code(for university home works) here is one.
GETLCA(BINARYTREE BT, NODE A, NODE B)
IF Root==NIL
return NIL
ENDIF
IF Root==A OR root==B
return Root
ENDIF
Left = GETLCA (Root.Left, A, B)

IF Left! = NIL AND Right! = NIL
return root
ELSEIF Left! = NIL
Return Left

This function will tell you the x,y position of the element relative to the page. Basically you have to loop up through all the element's parents and add their offsets together.
function getPos(el) {
// yay readability
for (var lx=0, ly=0;
el != null;
lx += el.offsetLeft, ly += el.offsetTop, el = el.offsetParent);
return {x: lx,y: ly};
}
However, if you just wanted the x,y position of the element relative to its container, then all you need is:
var x = el.offsetLeft, y = el.offsetTop;
To put an element directly below this one, you'll also need to know its height. This is stored in the offsetHeight/offsetWidth property.
var yPositionOfNewElement = el.offsetTop + el.offsetHeight + someMargin;
Also after React v 16.8+ you have an ability to use hooks
import React, {useState} from 'react';
const ControlledInputs = () => {
const [firstName, setFirstName] = useState(false);
const handleSubmit = (e) => {
e.preventDefault();
if (firstName) {
console.log('firstName :>> ', firstName);
}
};
return (
<>
<form onSubmit={handleSubmit}>
<label htmlFor="firstName">Name: </label>
<input
type="text"
id="firstName"
name="firstName"
value={firstName}
onChange={(e) => setFirstName(e.target.value)}
/>
<button type="submit">add person</button>
</form>
</>
);
};
The syntax of ng-style
is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:
<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>
And then in your controller:
$scope.width = '900px';
$scope.bgColor = 'red';
This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.
I shall refer to the same sample of data as posted in the question:
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randn(8, 4), columns=['A','B','C','D'])
print('The original data frame is: \n{}'.format(df))
Running this code will give you
The original data frame is:
A B C D
0 0.494824 -0.328480 0.818117 0.100290
1 0.239037 0.954912 -0.186825 -0.651935
2 -1.818285 -0.158856 0.359811 -0.345560
3 -0.070814 -0.394711 0.081697 -1.178845
4 -1.638063 1.498027 -0.609325 0.882594
5 -0.510217 0.500475 1.039466 0.187076
6 1.116529 0.912380 0.869323 0.119459
7 -1.046507 0.507299 -0.373432 -1.024795
Now you wish to append a new row to this data frame, which doesn't need to be copy of any other row in the data frame. @Alon suggested an interesting approach to use df.loc
to append a new row with different index. The issue, however, with this approach is if there is already a row present at that index, it will be overwritten by new values. This is typically the case for datasets when row index is not unique, like store ID in transaction datasets. So a more general solution to your question is to create the row, transform the new row data into a pandas series, name it to the index you want to have and then append it to the data frame. Don't forget to overwrite the original data frame with the one with appended row. The reason is df.append
returns a view of the dataframe and does not modify its contents. Following is the code:
row = pd.Series({'A':10,'B':20,'C':30,'D':40},name=3)
df = df.append(row)
print('The new data frame is: \n{}'.format(df))
Following would be the new output:
The new data frame is:
A B C D
0 0.494824 -0.328480 0.818117 0.100290
1 0.239037 0.954912 -0.186825 -0.651935
2 -1.818285 -0.158856 0.359811 -0.345560
3 -0.070814 -0.394711 0.081697 -1.178845
4 -1.638063 1.498027 -0.609325 0.882594
5 -0.510217 0.500475 1.039466 0.187076
6 1.116529 0.912380 0.869323 0.119459
7 -1.046507 0.507299 -0.373432 -1.024795
3 10.000000 20.000000 30.000000 40.000000

Here is the Latest solution of the problem:
In your CSS file write the following class called .clearfix along with the pseudo selector :after
.clearfix:after {
content: "";
display: table;
clear: both;
}
Then, in your HTML, add the .clearfix class to your parent Div. For example:
<div class="clearfix">
<div></div>
<div></div>
</div>
It should work always. You can call the class name as .group instead of .clearfix , as it will make the code more semantic. Note that, it is Not necessary to add the dot or even a space in the value of Content between the double quotation "".

To remove all array elements irrespective of any given id, use this:
collection.update(

);
You got a ninja ')'.

I realize this is a bit late, but I've had success with annotating a timestamp column with
@Column(name="timestamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
This should also work with CURRENT_DATE
and CURRENT_TIME
. I'm using JPA/Hibernate with Oracle, so YMMV.
The best solution is the attribute selector in CSS (input[type="text"]
) as the others suggested.
But if you have to support Internet Explorer 6, you cannot use it (QuirksMode). Well, only if you have to and also are willing to support it.
In this case your only option seems to be to define classes on input elements.
<input type="text" class="input-box" ... />
<input type="submit" class="button" ... />
...
and target them with a class selector:
input.input-box, textarea { background: cyan; }
In order to populate all of the column names into a comma-delimited list for a Select statement for the solutions mentioned for this question, I use the following options as they are a little less verbose than most responses here. Although, most responses here are still perfectly acceptable, however.
1)
SELECT column_name + ','
FROM information_schema.columns
WHERE table_name = 'YourTable'
2) This is probably the simplest approach to creating columns, if you have SQL Server SSMS.
1) Go to the table in Object Explorer and click on the + to the left of the table name or double-click the table name to open the sub list.
2) Drag the column subfolder over to the main query area and it will autopaste the entire column list for you.
With Go 1.5 they seem to have improved the cross compilation process, meaning it is built in now. No ./make.bash
-ing or brew
-ing required. The process is described here but for the TLDR-ers (like me) out there: you just set the GOOS
and the GOARCH
environment variables and run the go build.
For the even lazier copy-pasters (like me) out there, do something like this if you're on a *nix system:
env GOOS=linux GOARCH=arm go build -v github.com/path/to/your/app
You even learned the env
trick, which let you set environment variables for that command only, completely free of charge.

import sklearn
print('The scikit-learn version is {}.'.format(sklearn.__version__))
print('The scikit-learn version is '+ str(nltk.__version__))
Datatables only can order by DateTime in "ISO-8601" format, so you have to convert your date in "date-order" to this format (example using Razor):
<td data-sort="@myDate.ToString("o")">@myDate.ToShortDateString() - @myDate.ToShortTimeString()</td>
Option 1: Likely fastest (but not supported by some browsers if used on Document or SVGElement) :
var elements = document.getElementById('parentContainer').children;
Option 2: Likely slowest :
var elements = document.getElementById('parentContainer').getElementsByTagName('*');
Option 3: Requires change to code (wrap a form instead of a div around it) :
// Since what you're doing looks like it should be in a form...
var elements = document.forms['parentContainer'].elements;
var matches = [];
for (var i = 0; i < elements.length; i++)
if (elements[i].value.indexOf('q17_') == 0)
matches.push(elements[i]);

DateTimeFormat
, introduced in java 8:The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.
Your input format looks quite standard, except the trailing Z
. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
. The trailing 'Z'
is the interesting part. Usually there's time zone data here, like -0700
. So the pattern would be ...Z
, i.e. without apostrophes.
The output format is way more simple: "dd-MM-yyyy"
. Mind the small y
-s.
Here is the example code:
DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018
SimpleDateFormat
SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018
If you're targeting iOS 7 and 8, you need something like this to make sure you're using the right method for each version, because UIAlertView
is deprecated in iOS 8, but UIAlertController
is not available in iOS 7:
func alert(title: String, message: String) {
if let getModernAlert: AnyClass = NSClassFromString("UIAlertController") { // iOS 8
let myAlert: UIAlertController = UIAlertController(title: title, message: message, preferredStyle: .Alert)
myAlert.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
self.presentViewController(myAlert, animated: true, completion: nil)
} else { // iOS 7
let alert: UIAlertView = UIAlertView()
alert.delegate = self
alert.title = title
alert.message = message
alert.addButtonWithTitle("OK")
alert.show()
}
}
I achieved it using some extension methods
private const string endFieldPattern = "^(.*?)>";
public static MvcHtmlString IsDisabled(this MvcHtmlString htmlString, bool disabled)
{
string rawString = htmlString.ToString();

}
return new MvcHtmlString(rawString);
}
public static MvcHtmlString IsReadonly(this MvcHtmlString htmlString, bool @readonly)
{
string rawString = htmlString.ToString();

{
rawString = Regex.Replace(rawString, endFieldPattern, "$1 readonly=\"readonly\">");
}
return new MvcHtmlString(rawString);

I believe that I have the simplest answer yet using Spring Boot 1.4, included imports for the test class.:

//, or created in setup block
@Before
public void setup() {
someClass = new SomeClass();
}
@Test
public void postTest() {
String json = mapper.writeValueAsString(someClass);
mvc.perform(post("/someControllerUrl")

String x = "stack overflow";
String reversed = "";
for(int i = x.length()-1 ; i>=0; i--){
reversed = reversed+ x.charAt(i);
}
System.out.println("reversed string is : "+ reversed);
TextView pf = new TextView(context);
pf.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
For different layouts like ConstraintLayout
and others, they have their own LayoutParams
, like so:
pf.setLayoutParams(new ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
or
parentView.addView(pf, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
System.String is a reference type and already "nullable".
Nullable<T> and the ? suffix are for value types such as Int32, Double, DateTime, etc.
Use like this
<div ng-if="data.IsActive === 1">InActive</div>
<div ng-if="data.IsActive === 0">Active</div>
I had to edit /etc/apache2/sites-available/default
. The lines are the same as mentioned by RDL.
Check out parse_url()
:
$url = 'http://google.com/dhasjkdas/sadsdds/sdda/sdads.html';
$parse = parse_url($url);
echo $parse['host']; // prints 'google.com'
parse_url
doesn't handle really badly mangled urls very well, but is fine if you generally expect decent urls.
Check if you have set restrict outgoing SMTP to only some system users (root, MTA, mailman...). That restriction may prevent the spammers, but will redirect outgoing SMTP connections to the local mail server.

Since none of the answers are up to date with the last version of Pandas, I am writing another solution for this problem:
In [1]:
import pandas as pd
# Set exemple
df2 = pd.DataFrame({'X' : ['X1', 'X1', 'X1', 'X1'], 'Y' : ['Y2','Y1','Y1','Y1'], 'Z' : ['Z3','Z1','Z1','Z2']})
# Pivot
pd.crosstab(index=df2['Y'], columns=df2['Z'], values=df2['X'], aggfunc=pd.Series.nunique)
Out [1]:
Z Z1 Z2 Z3
Y
Y1 1.0 1.0 NaN
Y2 NaN NaN 1.0
There are many ways to skip the first line. In addition to those said by Bakuriu, I would add:
with open(filename, 'r') as f:
next(f)
for line in f:
and:
with open(filename,'r') as f:
lines = f.readlines()[1:]
Suppose I have committed changes to master branch.I will get the commit id(xyz) of the commit now i have to go to branch for which i need to push my commits.
Single commit id xyx
git checkout branch-name
git cherry-pick xyz
git push origin branch-name
Multiple commit id's xyz abc qwe
git checkout branch-name
git cherry-pick xyz abc qwe
git push origin branch-name
If you don't mind getting a new data frame object returned as opposed to updating the original Pandas .assign() will avoid SettingWithCopyWarning
. Your example:
df = df.assign(B=df1['E'])
If you want to stick with the same sort of loop then this will work:
Option Explicit
Sub selectColumns()
Dim topSelection As Integer
Dim endSelection As Integer
topSelection = 2
endSelection = 10
Dim columnSelected As Integer
columnSelected = 1
Do
With Excel.ThisWorkbook.ActiveSheet
.Range(.Cells(columnSelected, columnSelected), .Cells(endSelection, columnSelected)).Select
End With
columnSelected = columnSelected + 1
Loop Until columnSelected > 10
End Sub
EDIT
If in reality you just want to loop through every cell in an area of the spreadsheet then use something like this:
Sub loopThroughCells()
'=============
'this is the starting point
Dim rwMin As Integer
Dim colMin As Integer
rwMin = 2
colMin = 2
'=============
'=============
'this is the ending point
Dim rwMax As Integer
Dim colMax As Integer
rwMax = 10
colMax = 5
'=============
'=============
'iterator
Dim rwIndex As Integer
Dim colIndex As Integer
'=============
For rwIndex = rwMin To rwMax
For colIndex = colMin To colMax
Cells(rwIndex, colIndex).Select
Next colIndex
Next rwIndex
End Sub
We have Collection as below:
Syntax:
{{(Collection/array/list | filter:{Value : (object value)})[0].KeyName}}
Example:
{{(Collectionstatus | filter:{Value:dt.Status})[0].KeyName}}
-OR-
Syntax:
ng-bind="(input | filter)"
Example:
ng-bind="(Collectionstatus | filter:{Value:dt.Status})[0].KeyName"
Also you can try zenity !
user=$(zenity --entry --text 'Please enter the username:') || exit 1
While Orion Edwards Answer works for any situation, it may be a pain to add the border and set the properties of the border every time you want to do this. Another quick way is to set the padding of the text block:
<TextBlock Height="22" Padding="3" />
Similar to GnrlKnowledge, you can clear the Clipboard
http://developer.android.com/reference/android/text/ClipboardManager.html
If you want, preserve the text in the Clipboard, and on onDestroy, you can set it again.
Here is a step-by-step solution:
Add a script called run.py
in /home/bodacydo/work/project
and edit it like this:
import programs.my_python_program programs.my_python_program.main()
(replace main()
with your equivalent method in my_python_program
.)
/home/bodacydo/work/project
run.py
Explanation:
Since python appends to PYTHONPATH the path of the script from which it runs, running run.py
will append /home/bodacydo/work/project
. And voilà, import foo.tasks
will be found.
lost a couple of hours to this problem too. got it going though:
"access denied" in my case really did mean "access denied". mssqlstudio's user account on my windows device did NOT have full control of the folder specified in the error message. i gave it full control. access was no longer denied and the restore succeeded.
why was the folder locked up for studio ? who knows ? i got enough questions to deal with as it is without trying to answer more.
How element visibility and jQuery works;
An element could be hidden with display:none
, visibility:hidden
or opacity:0
. The difference between those methods:
display:none
hides the element, and it does not take up any space;visibility:hidden
hides the element, but it still takes up space in the layout;opacity:0
hides the element as "visibility:hidden", and it still takes up space in the layout; the only difference is that opacity lets one to make an element partly transparent;
if ($('.target').is(':hidden')) {
$('.target').show();
} else {
$('.target').hide();
}
if ($('.target').is(':visible')) {
$('.target').hide();
} else {
$('.target').show();
}
if ($('.target-visibility').css('visibility') == 'hidden') {
$('.target-visibility').css({
visibility: "visible",
display: ""
});

Themes downloaded from IntelliJ can be installed as a Plugin.
Take these steps:
Preferences -> Plugins -> GearIcon -> Install Plugin from disk -> Reset your IDE -> Preferences -> Appearance -> Theme -> Select your theme.
To solve your error I propose this solution: to work on Visual studio code editor and install live server extension in the editor, which allows you to connect to your local server, for me I put the picture in my workspace 127.0.0.1:5500/workspace/data/pict.png and it works!

You asked about performance. See this perf test comparing 'concat', '+' and 'join' - in short the + operator wins by far.

In vb.net you can actually compare strings with =
. Even though String
is a reference type, in vb.net =
on String
has been redefined to do a case-sensitive comparison of contents of the two strings.
You can test this with the following code. Note that I have taken one of the values from user input to ensure that the compiler cannot use the same reference for the two variables like the Java compiler would if variables were defined from the same string Literal. Run the program, type "This" and press <Enter>.
Sub Main()
Dim a As String = New String("This")
Dim b As String
b = Console.ReadLine()
If a = b Then
Console.WriteLine("They are equal")
Else
Console.WriteLine("Not equal")
End If
Console.ReadLine()

There is a deleted answer on this question that had a useful link: https://help.github.com/articles/duplicating-a-repository
The gist is
0. create the new empty repository (say, on github)
1. make a bare clone of the repository in some temporary location
2. change to the temporary location
3. perform a mirror-push to the new repository
4. change to another location and delete the temporary location
OP's example:
On your local machine
$ cd $HOME
$ git clone --bare https://git.fedorahosted.org/the/path/to/my_repo.git
$ cd my_repo.git
$ git push --mirror https://github.com/my_username/my_repo.git
$ cd ..
$ rm -rf my_repo.git

Keep in mind, I'm completely biased (PMC Chair of CXF), but my thoughts:
From a strictly "can the project do what I need it to do" perspective, both are pretty equivalent. There some "edge case" things that CXF can do that Axis 2 cannot and vice versa. But for 90% of the use cases, either will work fine.
Thus, it comes down to a bunch of other things other than "check box features".
API - CXF pushes "standards based" API's (JAX-WS compliant) whereas Axis2 general goes toward proprietary things. That said, even CXF may require uses of proprietary API's to configure/control various things outside the JAX-WS spec. For REST, CXF also uses standard API's (JAX-RS compliant) instead of proprietary things. (Yes, I'm aware of the JAX-WS runtime in Axis2, but the tooling and docs and everything doesn't target it)
Community aspects and supportability - CXF prides itself on responding to issues and making "fixpacks" available to users. CXF did 12 fixpacks for 2.0.x (released two years ago, so about every 2 months), 6 fixpacks to 2.1.x, and now 3 for 2.2.x. Axis2 doesn't really "support" older versions. Unless a "critical" issue is hit, you may need to wait till the next big release (they average about every 9-10 months or so) to get fixes. (although, with either, you can grab the source code and patch/fix yourself. Gotta love open source.)
Integration - CXF has much better Spring integration if you use Spring. All the configuration and such is done through Spring. Also, people tend to consider CXF as more "embeddable" (I've never looked at Axis2 from this perspective) into other applications. Not sure if things like that matter to you.
Performance - they both perform very well. I think Axis2's proprietary ADB databinding is a bit faster than CXF, but if you use JAXB (standards based API's again), CXF is a bit faster. When using more complex scenarios like WS-Security, the underlying security "engine" (WSS4J) is the same for both so the performance is completely comparable.
Not sure if that answers the question at all. Hope it at least provides some information.

If legend_out
is set to True
then legend is available thought g._legend
property and it is a part of a figure. Seaborn legend is standard matplotlib legend object. Therefore you may change legend texts like:
import seaborn as sns
tips = sns.load_dataset("tips")
g = sns.lmplot(x="total_bill", y="tip", hue="smoker",
data=tips, markers=["o", "x"], legend_out = True)
# title
new_title = 'My title'
g._legend.set_title(new_title)
# replace labels
new_labels = ['label 1', 'label 2']
for t, l in zip(g._legend.texts, new_labels): t.set_text(l)
sns.plt.show()
Another situation if legend_out
is set to False
. You have to define which axes has a legend (in below example this is axis number 0):
import seaborn as sns
tips = sns.load_dataset("tips")
g = sns.lmplot(x="total_bill", y="tip", hue="smoker",
data=tips, markers=["o", "x"], legend_out = False)
# check axes and find which is have legend
leg = g.axes.flat[0].get_legend()
new_title = 'My title'
leg.set_title(new_title)
new_labels = ['label 1', 'label 2']
for t, l in zip(leg.texts, new_labels): t.set_text(l)
sns.plt.show()
Moreover you may combine both situations and use this code:
import seaborn as sns
tips = sns.load_dataset("tips")
g = sns.lmplot(x="total_bill", y="tip", hue="smoker",
data=tips, markers=["o", "x"], legend_out = True)
# check axes and find which is have legend
for ax in g.axes.flat:
leg = g.axes.flat[0].get_legend()
if not leg is None: break
# or legend may be on a figure
if leg is None: leg = g._legend
# change legend texts
new_title = 'My title'
leg.set_title(new_title)
new_labels = ['label 1', 'label 2']
for t, l in zip(leg.texts, new_labels): t.set_text(l)
sns.plt.show()
This code works for any seaborn plot which is based on Grid
class.
Use:
sb.AppendLine();
sb.Append("\t");
for better portability. Environment.NewLine
may not necessarily be \n
; Windows uses \r\n
, for example.
Swift 2.0 solution is here:
let urlStr = “http://url_to_manage_post_requests”
let url = NSURL(string: urlStr)
let request: NSMutableURLRequest =
NSMutableURLRequest(URL: url!) request.HTTPMethod = "POST"
request.setValue(“application/json” forHTTPHeaderField:”Content-Type”)
request.timeoutInterval = 60.0
//additional headers
request.setValue(“deviceIDValue”, forHTTPHeaderField:”DeviceId”)
let bodyStr = “string or data to add to body of request”
let bodyData = bodyStr.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPBody = bodyData
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request){
(data: NSData?, response: NSURLResponse?, error: NSError?) -> Void in
if let httpResponse = response as? NSHTTPURLResponse {
print("responseCode \(httpResponse.statusCode)")
}
if error != nil {
// You can handle error response here
print("\(error)")
}else {
//Converting response to collection formate (array or dictionary)
do{
let jsonResult: AnyObject = (try NSJSONSerialization.JSONObjectWithData(data!, options:
NSJSONReadingOptions.MutableContainers))
//success code
}catch{
//failure code
}
}
}
task.resume()
The terms resource and endpoint are often used synonymously. But in fact they do not mean the same thing.
The term endpoint is focused on the URL that is used to make a request.
The term resource is focused on the data set that is returned by a request.
Now, the same resource can often be accessed by multiple different endpoints.
Also the same endpoint can return different resources, depending on a query string.
Let us see some examples:
Have a look at the following examples of different endpoints:
/api/companies/5/employees/3
/api/v2/companies/5/employees/3
/api/employees/3
They obviously could all access the very same resource in a given API.
Also an existing API could be changed completely. This could lead to new endpoints that would access the same old resources using totally new and different URLs:
/api/employees/3
/new_api/staff/3
If your endpoint returns a collection, you could implement searching/filtering/sorting using query strings. As a result the following URLs all use the same endpoint (/api/companies
), but they can return different resources (or resource collections, which by definition are resources in themselves):
/api/companies
/api/companies?sort=name_asc
/api/companies?location=germany
/api/companies?search=siemens
Alternatively,
1) Without touching System.Reflection
namespace,
GETNAME(new { myInput });
public static string GETNAME<T>(T myInput) where T : class
{
if (myInput == null)
return string.Empty;
return myInput.ToString().TrimStart('{').TrimEnd('}').Split('=')[0].Trim();
}
2) The below one can be faster though (from my tests)
GETNAME(new { variable });
public static string GETNAME<T>(T myInput) where T : class
{
if (myInput == null)
return string.Empty;
return typeof(T).GetProperties()[0].Name;
}
You can also extend this for properties of objects (may be with extension methods):
new { myClass.MyProperty1 }.GETNAME();
You can cache property values to improve performance further as property names don't change during runtime.
The Expression approach is going to be slower for my taste. To get parameter name and value together in one go see this answer of mine
Not exactly elegant, but the best (and quickest) solution i could find was using OnError. This will be significantly faster than iteration for any medium to large collection.
Public Function InCollection(col As Collection, key As String) As Boolean
Dim var As Variant
Dim errNumber As Long
InCollection = False
Set var = Nothing
Err.Clear
On Error Resume Next
var = col.Item(key)
errNumber = CLng(Err.Number)
On Error GoTo 0
'5 is not in, 0 and 438 represent incollection
If errNumber = 5 Then ' it is 5 if not in collection
InCollection = False
Else
InCollection = True
End If
End Function
Here is what I did to by-pass the issue.
1) Go to backup
2) Remove the destination file-path to disk
3) Click on Add
4) In the File name: check box manually type in the backup name after ..\backup like below where Yourdb.bak is the database backup name
C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup\Yourdb.bak
5) Click on OK
Hope this helps!
On Ubuntu,
sudo dpkg-reconfigure mysql-server-5.5
Replace 5.5
with your current version and you will be asked for the new root password.
This solution does the following:
Uses the ES6 spread operator to convert the NodeList of all div
s to an array.
Provides output if the div
contains the query string, not just if it exactly equals the query string (which happens for some of the other answers). e.g. It should provide output not just for 'SomeText' but also for 'SomeText, text continues'.
Outputs the entire div
contents, not just the query string. e.g. For 'SomeText, text continues' it should output that whole string, not just 'SomeText'.
Allows for multiple div
s to contain the string, not just a single div
.
[...document.querySelectorAll('div')] // get all the divs in an array_x000D_
.map(div => div.innerHTML) // get their contents_x000D_
.filter(txt => txt.includes('SomeText')) // keep only those containing the query_x000D_
.forEach(txt => console.log(txt)); // output the entire contents of those
_x000D_
<div>SomeText, text continues.</div>_x000D_
<div>Not in this div.</div>_x000D_
<div>Here is more SomeText.</div>
_x000D_
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.
According to this answer, adding the -t
flag will prevent the container from exiting when running in the background. You can then use docker exec -i -t <image> /bin/bash
to get into a shell prompt.
docker run -t -d <image> <command>
It seems that the -t option isn't documented very well, though the help says that it "allocates a pseudo-TTY."
Pass cls
parameter into @classmethod
to resolve this problem.
@classmethod
def test(cls):
return ''
The sender is the control that the action is for (say OnClick, it's the button).
The EventArgs are arguments that the implementor of this event may find useful. With OnClick it contains nothing good, but in some events, like say in a GridView 'SelectedIndexChanged', it will contain the new index, or some other useful data.
What Chris is saying is you can do this:
protected void someButton_Click (object sender, EventArgs ea)
{
Button someButton = sender as Button;
if(someButton != null)
{
someButton.Text = "I was clicked!";
}
}
