SET UP THE REPOSITORY
For Ubuntu 14.04/16.04/16.10/17.04:
sudo add-apt-repository "deb [arch=amd64] \
https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
For Ubuntu 17.10:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable"
Add Docker’s official GPG key:
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Then install
$ sudo apt-get update && sudo apt-get -y install docker-ce
This:
Console.WriteLine( "StartingMonthColumn is {0}", ConfigurationManager.AppSettings["StartingMonthColumn"]);
works fine for me.
Note that ConfigurationManager
is in the System.Configuration
namespace (so you'll likely want a using System.Configuration;
statement), and that since what you read in has a string type you'll need to parse what you read in to use it as a number.
Also, be sure you set system.configuration.dll
as a reference in your project or build script.

On an EC2 at AWS, I did this:
yum list | grep imagick
Then found a list of ones I could install...
php -v
told me which version of php I had and thus which version of imagick
yum install php56-pecl-imagick.x86_64
Did the trick. Enjoy!
I see some people prefer to generate sources into the target via jaxws-maven-plugin AND make this classes visible in source via build-helper-maven-plugin. As an argument for this structure
the version management system (svn/etc.) would always notice changed sources
With git it is not true. So you can just configure jaxws-maven-plugin
to put them into your sources, but not under the target folder. Next time you build your project, git will not mark these generated files as changed. Here is the simple solution with only one plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<version>2.6</version>
<dependencies>
<dependency>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-fluent-api</artifactId>
<version>3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-tools</artifactId>
<version>2.3.0</version>
</dependency>
</dependencies>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<packageName>som.path.generated</packageName>
<xjcArgs>
<xjcArg>-Xfluent-api</xjcArg>
</xjcArgs>
<verbose>true</verbose>
<keep>true</keep> <!--used by default-->
<sourceDestDir>${project.build.sourceDirectory}</sourceDestDir>
<wsdlDirectory>src/main/resources/META-INF/wsdl</wsdlDirectory>
<wsdlLocation>META-INF/wsdl/soap.wsdl</wsdlLocation>
</configuration>
</execution>
</executions>
</plugin>
Additionally (just to note) in this example SOAP classes are generated with Fluent API, so you can create them like:
A a = new A()
.withField1(value1)
.withField2(value2);
You need to use the wildcard % :
SELECT * from games WHERE (lower(title) LIKE 'age of empires III%');

I cringe every time I use create_function()
in php.
Parameters are a coma separated string, the whole function body in a string... Argh... I think they could not have made it uglier even if they tried.
Unfortunately, it is the only choice when creating a named function is not worth the trouble.
You could look at using Lattice. In this example I have defined a grid over which I want to plot z~x,y. It looks something like this. Note that most of the code is just building a 3D shape that I plot using the wireframe function.
The variables "b" and "s" could be x or y.
require(lattice)
# begin generating my 3D shape
b <- seq(from=0, to=20,by=0.5)
s <- seq(from=0, to=20,by=0.5)
payoff <- expand.grid(b=b,s=s)
payoff$payoff <- payoff$b - payoff$s
payoff$payoff[payoff$payoff < -1] <- -1
# end generating my 3D shape
wireframe(payoff ~ s * b, payoff, shade = TRUE, aspect = c(1, 1),
light.source = c(10,10,10), main = "Study 1",
scales = list(z.ticks=5,arrows=FALSE, col="black", font=10, tck=0.5),
screen = list(z = 40, x = -75, y = 0))
In Angular 5.12 and latest Angular CLI, do

I have just faced the same problem. First, you need to install the appropriate Oracle client for your OS. In my case, to install it on Ubuntu x64 I have followed this instructions https://help.ubuntu.com/community/Oracle%20Instant%20Client#Install_RPMs
Then, you need to install cx_Oracle, a Python module to connect to the Oracle client. Again, assuming you are running Ubuntu in a 64bit machine, you should type in a shell:
wget -c http://prdownloads.sourceforge.net/cx-oracle/cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
sudo alien -i cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
This will work for Oracle 11g if you have installed Python 2.7.x, but you can download a different cx_Oracle version in http://cx-oracle.sourceforge.net/ To check which Python version do you have, type in a terminal:
python -V
I hope it helps
You have to pass instance of MainActivity into another class, then you can call everything public (in MainActivity) from everywhere.
MainActivity.java
public class MainActivity extends AppCompatActivity {
// Instance of AnotherClass for future use
private AnotherClass anotherClass;
@Override
protected void onCreate(Bundle savedInstanceState) {
// Create new instance of AnotherClass and
// pass instance of MainActivity by "this"
anotherClass = new AnotherClass(this);
}
// Method you want to call from another class
public void startChronometer(){
...
}
}
AnotherClass.java
public class AnotherClass {
// Main class instance
private MainActivity mainActivity;
// Constructor
public AnotherClass(MainActivity activity) {
// Save instance of main class for future use
mainActivity = activity;
// Call method in MainActivity
mainActivity.startChronometer();
}
}
I don't know why everyone forgot to mention the amazing capability of set
s in python. You can simply cast your list into a set and then remove whatever you want to remove in a simple expression like so:
>>> item_list = ['item', 5, 'foo', 3.14, True]
>>> item_list = set(item_list) - {'item', 5}
>>> item_list
{True, 3.14, 'foo'}
>>> # you can cast it again in a list-from like so
>>> item_list = list(item_list)
>>> item_list
[True, 3.14, 'foo']
Yes, the higher the z-index, the better. It will position your content element on top of every other element on the page. Say you have z-index to some elements on your page. Look for the highest and then give a higher z-index to your popup element. This way it will flow even over the other elements with z-index. If you don't have a z-index in any element on your page, you should give like z-index:2; or something higher.
Just addition to above answers ..
[FromUri] can also be used to bind complex types from uri parameters instead of passing parameters from querystring
For Ex..
public class GeoPoint
{
public double Latitude { get; set; }
public double Longitude { get; set; }
}
[RoutePrefix("api/Values")]
public ValuesController : ApiController
{
[Route("{Latitude}/{Longitude}")]
public HttpResponseMessage Get([FromUri] GeoPoint location) { ... }
}
Can be called like:
http://localhost/api/values/47.678558/-122.130989

I am learning javascript and jquery and was going through all the answer,
i faced same issue when calling javascript function for loading div element.
I tried $('<divid>').ready(function(){alert('test'})
and it worked for me. I want to know is this good way to perform onload call on div element in the way i did using jquery selector.
thanks
I found 3 ways to return a variable's type at runtime:
Using string formatting
func typeof(v interface{}) string {
return fmt.Sprintf("%T", v)
}
Using reflect package
func typeof(v interface{}) string {
return reflect.TypeOf(v).String()
}
Using type assertions
func typeof(v interface{}) string {
switch v.(type) {
case int:
return "int"
case float64:
return "float64"
//... etc
default:
return "unknown"
}
}
Every method has a different best use case:
string formatting - short and low footprint (not necessary to import reflect package)
reflect package - when need more details about the type we have access to the full reflection capabilities
type assertions - allows grouping types, for example recognize all int32, int64, uint32, uint64 types as "int"
Below is Example of simple dropdown using jstl tag
<form:select path="cityFrom">
<form:option value="Ghaziabad" label="Ghaziabad"/>
<form:option value="Modinagar" label="Modinagar"/>
<form:option value="Meerut" label="Meerut"/>
<form:option value="Amristar" label="Amristar"/>
</form:select>
If response is in json and not a string then
alert(response.id);
or
alert(response['id']);
otherwise
var response = JSON.parse('{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}');
response.id ; //# => 2231f87c-a62c-4c2c-8f5d-b76d11942301
To anyone else looking for this, I wasn't able to use certutil -importpfx
into a specific store, and I didn't want to download the importpfx tool supplied by jaspernygaard's answer in order to avoid the requirement of copying the file to a large number of servers. I ended up finding my answer in a powershell script shown here.
The code uses System.Security.Cryptography.X509Certificates
to import the certificate and then moves it into the desired store:
function Import-PfxCertificate {
param([String]$certPath,[String]$certRootStore = “localmachine”,[String]$certStore = “My”,$pfxPass = $null)
$pfx = new-object System.Security.Cryptography.X509Certificates.X509Certificate2
if ($pfxPass -eq $null)
{
$pfxPass = read-host "Password" -assecurestring
}
$pfx.import($certPath,$pfxPass,"Exportable,PersistKeySet")
$store = new-object System.Security.Cryptography.X509Certificates.X509Store($certStore,$certRootStore)
$store.open("MaxAllowed")
$store.add($pfx)
$store.close()
}
You can use either SEQUENCE
or TRIGGER
to increment automatically the value of a given column in your database table however the use of TRIGGERS
would be more appropriate. See the following documentation of Oracle that contains major clauses used with triggers with suitable examples.
Use the CREATE TRIGGER statement to create and enable a database trigger, which is:
A stored PL/SQL block associated with a table, a schema, or the database or
An anonymous PL/SQL block or a call to a procedure implemented in PL/SQL or Java
Oracle Database automatically executes a trigger when specified conditions occur. See.
Following is a simple TRIGGER
just as an example for you that inserts the primary key value in a specified table based on the maximum value of that column. You can modify the schema name, table name etc and use it. Just give it a try.
/*Create a database trigger that generates automatically primary key values on the CITY table using the max function.*/
CREATE OR REPLACE TRIGGER PROJECT.PK_MAX_TRIGGER_CITY
BEFORE INSERT ON PROJECT.CITY
FOR EACH ROW
DECLARE
CNT NUMBER;
PKV CITY.CITY_ID%TYPE;
NO NUMBER;
BEGIN
SELECT COUNT(*)INTO CNT FROM CITY;
IF CNT=0 THEN
PKV:='CT0001';
ELSE
SELECT 'CT'||LPAD(MAX(TO_NUMBER(SUBSTR(CITY_ID,3,LENGTH(CITY_ID)))+1),4,'0') INTO PKV
FROM CITY;
END IF;
:NEW.CITY_ID:=PKV;
END;
Would automatically generates values such as CT0001
, CT0002
, CT0002
and so on and inserts into the given column of the specified table.
Java implicitly assumes a reference to the current object for methods called like this. So
// Test2.java
public class Test2 {
public void testMethod() {
testMethod2();
}
// ...
}
Is exactly the same as
// Test2.java
public class Test2 {
public void testMethod() {
this.testMethod2();
}
// ...
}
I prefer the second version to make more clear what you want to do.
use this function to get a standard array back of the type you are after...
return get_object_vars($booking);
Try using the data
option of the $.ajax
function. More info here.
$('#btnSaveComments').click(function () {
var comments = $('#txtComments').val();
var selectedId = $('#hdnSelectedId').val();
$.ajax({
url: '<%: Url.Action("SaveComments")%>',
data: { 'id' : selectedId, 'comments' : comments },
type: "post",
cache: false,
success: function (savingStatus) {
$("#hdnOrigComments").val($('#txtComments').val());
$('#lblCommentsNotification').text(savingStatus);
},
error: function (xhr, ajaxOptions, thrownError) {
$('#lblCommentsNotification').text("Error encountered while saving the comments.");
}
});
});
Try this:
<div>
<p onclick="startAnimation()">Start</p><!--O botão para iniciar (start)-->
<div id="animation">Hello!</div> <!--O elemento que você quer animar-->
</div>
<style>
@keyframes animationName {
from {margin-left:-30%;}
}
</style>
<script>
function startAnimation() {
document.getElementById("animation").style.animation = "animationName 2s linear 1";
}
</script>
Here git-update-index - Register file contents in the working tree to the index.
git update-index --assume-unchanged <PATH_OF_THE_FILE>
Example:-
git update-index --assume-unchanged somelocation/pom.xml
use cin.ignore(1000,'\n')
to clear all of chars of the previous cin.get()
in the buffer and it will choose to stop when it meet '\n' or 1000 chars
first.
You could just try using return false (return false overrides default behaviour on every DOM element) like that :
myform.onsubmit = function ()
{
// do what you want
return false
}
and then submit your form using myform.submit()
or alternatively :
mybutton.onclick = function ()
{
// do what you want
return false
}
Also, if you use type="button"
your form will not be submitted.
If you have more files in your folder, you can use the below piped command I found in unix stackexchange.
find /some/dir/ -type f -print0 | xargs -0 shuf -e -n 8 -z | xargs -0 cp -vt /target/dir/
Here I wanted to copy the files, but if you want to move files or do something else, just change the last command where I have used cp
.
Here is simple but working function to truncate number upto 2 decimal places.
function truncateNumber(num) {
var num1 = "";
var num2 = "";
var num1 = num.split('.')[0];
num2 = num.split('.')[1];
var decimalNum = num2.substring(0, 2);
var strNum = num1 +"."+ decimalNum;
var finalNum = parseFloat(strNum);
return finalNum;
}
This will set the default to be the most current version of node
nvm alias default node
and then you'll need to run
nvm use default
or exit and open a new tab
Try the following function implemented in Swift 3.0 and above
func delayWithSeconds(_ seconds: Double, completion: @escaping () -> ()) {
DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {
completion()
}
}
Usage
delayWithSeconds(1) {
//Do something
}
The simplest solution is to use ThresholdFilter
on the appenders:
<appender name="..." class="...">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO</level>
</filter>
Full example:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO</level>
</filter>
<encoder>
<pattern>%d %-5level: %msg%n</pattern>
</encoder>
</appender>
<appender name="STDERR" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>
<target>System.err</target>
<encoder>
<pattern>%d %-5level: %msg%n</pattern>
</encoder>
</appender>
<root>
<appender-ref ref="STDOUT" />
<appender-ref ref="STDERR" />
</root>
</configuration>
Update: As Mike pointed out in the comment, messages with ERROR level are printed here both to STDOUT and STDERR. Not sure what was the OP's intent, though. You can try Mike's answer if this is not what you wanted.
Select [Column Name] into [New Table] from [Source Table]

If ad hoc updates to system catalog is "not supported", or if you get a "Msg 5808" then you will need to configure with override like this:
EXEC sp_configure 'show advanced options', 1
RECONFIGURE with override

EXEC sp_configure 'ad hoc distributed queries', 1
RECONFIGURE with override

ax.axis('off')
, will as Joe Kington pointed out, remove everything except the plotted line.
For those wanting to only remove the frame (border), and keep labels, tickers etc, one can do that by accessing the spines
object on the axis. Given an axis object ax
, the following should remove borders on all four sides:
ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['bottom'].set_visible(False)
ax.spines['left'].set_visible(False)
And, in case of removing x
and y
ticks from the plot:
ax.get_xaxis().set_ticks([])
ax.get_yaxis().set_ticks([])
python -m compileall <pythonic-project-name>
which compiles all .py
files to .pyc
files in a project which contains packages as well as modules.
python3 -m compileall <pythonic-project-name>
which compiles all .py
files to __pycache__
folders in a project which contains packages as well as modules.
Or with browning from this post:
You can enforce the same layout of
.pyc
files in the folders as in Python2 by using:
python3 -m compileall -b <pythonic-project-name>
The option
-b
triggers the output of.pyc
files to their legacy-locations (i.e. the same as in Python2).
For starters:
<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.
This would be the optimal solution:
<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>
>>> ord("a")
97
>>> chr(97)

Try this another way:
var qry = Employees
.OrderByDescending (s => s.EmpFName)
.ThenBy (s => s.Address)
.Select (s => s.EmpCode);
You can use a StringWriter to write values to a string. It provides a stream-like syntax (though does not derive from Stream
) which works with an underlying StringBuilder
.
Use Distinct()
but keep in mind that it uses the default equality comparer to compare values, so if you want anything beyond that you need to implement your own comparer.
Please see http://msdn.microsoft.com/en-us/library/bb348436.aspx for an example.
To get rid of the fixed height property you can set it to the default value:
height: auto;

Recordsets have two important properties when looping through data, EOF (End-Of-File) and BOF (Beginning-Of-File). Recordsets are like tables and when you loop through one, you are literally moving from record to record in sequence. As you move through the records the EOF property is set to false but after you try and go past the last record, the EOF property becomes true. This works the same in reverse for the BOF property.
These properties let us know when we have reached the limits of a recordset.

Please check which storage engine you are using. If it is MyISAM, then Transaction('COMMIT','ROLLBACK')
will not be supported because only the InnoDB storage engine, not MyISAM, supports transactions.

The closest validation of my theory i can find it from RFC 4253:
The "ssh-rsa" key format has the following specific encoding:
string "ssh-rsa" mpint e mpint n
Here the 'e' and 'n' parameters form the signature key blob.
But it doesn't explain the length prefixes.

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:
A.1.1 RSA public key syntax
An RSA public key should be represented with the ASN.1 type
RSAPublicKey
:RSAPublicKey ::= SEQUENCE { modulus INTEGER, -- n publicExponent INTEGER -- e }
The fields of type RSAPublicKey have the following meanings:
- modulus is the RSA modulus n.
- publicExponent is the RSA public exponent e.
Using Microsoft's excellent (and the only real) ASN.1 documentation:

if you are sure that you have uploaded the content of key.pub into GitLab, then:
1- Open Git Bash "Not CMD"
2- Browse to Solution Folder "CD Path"
3- Type Git Init
4- Type Git Add .
4- Type Git Commit
6- Type Git Push
and it will work.. another hint: make sure the path of the file where you copied the key is correct and equivalent to the same path it showed on CMD when creating the keys
If you want to do it in a manner more consistent with learning what goes on in the iteration try this
def merge_arrays(a, b):
l= []
while len(a) > 0 and len(b)>0:
if a[0] < b[0]: l.append(a.pop(0))
else:l.append(b.pop(0))
l.extend(a+b)
print( l )
Multiply values with -1 and use max heap to get the effect of min heap
You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.
You have two options:
Grant write permissions to the folder to the user or group you log in with (myuser
), or change the ownership of the folder to the user, or
Disable a transfer to temporary file.
In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:
For just reading the last element of a slice:
sl[len(sl)-1]
For removing it:
sl = sl[:len(sl)-1]
See this page about slice tricks
You can do like this:
a {font-size: 100px}
Try avoid using font tag because it's deprecated. Use CSS like above instead. You can give your anchors specific class and apply any style for them.
You should look for the error in the file error_log in the log directory. Maybe there are differences between your local and server configuration (db user/password etc.etc.)
usually the log file is in
/var/log/apache2/error.log
or
/var/log/httpd/error.log
if it is not the first two chars and you wanna remove F0 from the whole string then you gotta use this regex
let string = 'F0123F0456F0';_x000D_
let result = string.replace(/F0/ig, '');_x000D_
console.log(result);
_x000D_
You can apply the atuto_increment constraint to the data column by the following query:
ALTER TABLE customers MODIFY COLUMN customer_id BIGINT NOT NULL AUTO_INCREMENT;
But, if the columns are part of a foreign key constraint you, will most probably receive an error. Therefore, it is advised to turn off foreign_key_checks by using the following query:
SET foreign_key_checks = 0;
Therefore, use the following query instead:
SET foreign_key_checks = 0;
ALTER TABLE customers MODIFY COLUMN customer_id BIGINT NOT NULL AUTO_INCREMENT;
SET foreign_key_checks = 1;
I found this solution via PowerShell :
dir | rename-item -NewName {$_.name -replace "replaceME","MyNewTxt"}
This will rename parts of all the files in the current folder.

All other answers themselves didn't help me. But the following sum up did the job
Create ~/.config/apport/settings
with the following content:
[main]
unpackaged=true
(This tells apport to also write core dumps for custom apps)
check: ulimit -c
. If it outputs 0, fix it with
ulimit -c unlimited
Just for in case restart apport:
sudo systemctl restart apport
Crash files are now written in /var/crash/
. But you cannot use them with gdb. To use them with gdb, use
apport-unpack <location_of_report> <target_directory>
Further information:
core_pattern
. Be aware, that that file might get overwritten by the apport service on restarting.ulimit -c
value might get changed automatically while you're trying other answers of the web. Be sure to check it regularly during setting up your core dump creation.References:
I got rid of the same problem by doing following steps:
Xcode->Product->Clean Build Folder
(hold alt key on Product to see it)Xcode->Window->Organizer
and select Projects
tab. Then find your project and delete derived data
of the project.Try adding these options to socket.io:
const options = { transports: ['websocket'], pingTimeout: 3000, pingInterval: 5000 };
I hope this will help you !
Ok so i struggled for a long time trying to figure this out. Here is the nuclear option, for when you have exhausted all other ways..
When you are done, and it still works, import your actual code into this new project. Fix any compile errors the newer version of angular causes.
Thats what did it for me.. 1 hour of rework vs 6 hours of trying to figure out wtf was wrong.. wish i did it this way to start..
Javascript which runs on the client machine can't access the local disk file system due to security restrictions.
If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.
If you want to make it 2 way binding, you can use [(yourVar)]
, but you have to implement yourVarChange
event and call it everytime your variable change.
Something like this to track the hero change
@Output() heroChange = new EventEmitter();
and then when your hero get changed, call this.heroChange.emit(this.hero);
the [(hero)]
binding will do the rest for you
see example here:
The value returned by Date.prototype.toLocaleString is implementation dependent, so you get what you get. You can try to parse the string to remove seconds, but it may be different in different browsers so you'd need to make allowance for every browser in use.
Creating your own, unambiguous format isn't difficult using Date methods. For example:
function formatTimeHHMMA(d) {
function z(n){return (n<10?'0':'')+n}
var h = d.getHours();
return (h%12 || 12) + ':' + z(d.getMinutes()) + ' ' + (h<12? 'AM' :'PM');
}
You cannot get green/red text, but you can get green/red highlighted text using the diff language template. Example:
```diff
+ this text is highlighted in green
- this text is highlighted in red
```
My 2c for this is to implement the functionality you require to be called in a toolkit class and call that from wherever you need:
// Util.cs
static class Util
{
static void DoSomething( FooBase foo ) {}
}
// FooBase.cs
class FooBase
{
virtual void Do() { Util.DoSomething( this ); }
}
// FooDerived.cs
class FooDerived : FooBase
{
override void Do() { ... }
}
// FooDerived2.cs
class FooDerived2 : FooDerived
{
override void Do() { Util.DoSomething( this ); }
}
This does require some thought as to access privilege, you may need to add some internal
accessor methods to facilitate the functionality.
Even though there are many perfectly written answers to this question, I will add my inputs.
Say you have Element[] array = { new Element(1), new Element(2), new Element(3) };
New ArrayList can be created in the following ways
ArrayList<Element> arraylist_1 = new ArrayList<>(Arrays.asList(array));
ArrayList<Element> arraylist_2 = new ArrayList<>(
Arrays.asList(new Element[] { new Element(1), new Element(2), new Element(3) }));
// Add through a collection
ArrayList<Element> arraylist_3 = new ArrayList<>();
Collections.addAll(arraylist_3, array);
And they very well support all operations of ArrayList
arraylist_1.add(new Element(4)); // or remove(): Success
arraylist_2.add(new Element(4)); // or remove(): Success
arraylist_3.add(new Element(4)); // or remove(): Success
But the following operations returns just a List view of an ArrayList and not actual ArrayList.
// Returns a List view of array and not actual ArrayList
List<Element> listView_1 = (List<Element>) Arrays.asList(array);
List<Element> listView_2 = Arrays.asList(array);
List<Element> listView_3 = Arrays.asList(new Element(1), new Element(2), new Element(3));
Therefore, they will give error when trying to make some ArrayList operations
listView_1.add(new Element(4)); // Error
listView_2.add(new Element(4)); // Error
listView_3.add(new Element(4)); // Error

clone() was designed with several mistakes (see this question), so it's best to avoid it.
From Effective Java 2nd Edition, Item 11: Override clone judiciously
Given all of the problems associated with Cloneable, it’s safe to say that other interfaces should not extend it, and that classes designed for inheritance (Item 17) should not implement it. Because of its many shortcomings, some expert programmers simply choose never to override the clone method and never to invoke it except, perhaps, to copy arrays. If you design a class for inheritance, be aware that if you choose not to provide a well-behaved protected clone method, it will be impossible for subclasses to implement Cloneable.
This book also describes the many advantages copy constructors have over Cloneable/clone.
All standard collections have copy constructors. Use them.
List<Double> original = // some list
List<Double> copy = new ArrayList<Double>(original);
The z-index
property only works on elements with a position
value other than static
(e.g. position: absolute;
, position: relative;
, or position: fixed
).
There is also position: sticky;
that is supported in Firefox, is prefixed in Safari, worked for a time in older versions of Chrome under a custom flag, and is under consideration by Microsoft to add to their Edge browser.
Important
For regular positioning, be sure to include position: relative
on the elements where you also set the z-index
. Otherwise, it won't take effect.

You can also use SET IDENTITY INSERT
to allow you to insert values into an identity column.
Example:
SET IDENTITY_INSERT dbo.Tool ON
GO
And then you can insert into an identity column the values you need.
In many applications, like MsOffice (until version 2000 or 2002), the maximum number of characters per cell was 255. Moving data from programs able of handling more than 255 characters per field to/from those applications was a nightmare. Currently, the limit is less and less hindering.
Instead of adding Reader("Name")
you add a new ListItem
. ListItem
has a Text
and a Value
property that you can set.
So I'm myself new to React and I found a way to do it.
This solution does not require any extra packages.
In the above docs they mention export in Shell and other options, the one I'll attempt to explain is using .env file
1.1 create Root/.env
#.env file
REACT_APP_SECRET_NAME=secretvaluehere123
Important notes it MUST start with REACT_APP_
1.2 Access ENV variable
#App.js file or the file you need to access ENV
<p>print env secret to HTML</p>
<pre>{process.env.REACT_APP_SECRET_NAME}</pre>
handleFetchData() { // access in API call
fetch(`https://awesome.api.io?api-key=${process.env.REACT_APP_SECRET_NAME}`)
.then((res) => res.json())
.then((data) => console.log(data))
}
1.3 Build Env Issue
So after I did step 1.1|2 it was not working, then I found the above issue/solution. React read/creates env when is built so you need to npm run start every time you modify the .env file so the variables get updated.
If you are interested in using methods from multiple classes, the best way to approach to it is to use Composition instead of Inheritence
just fixing some small mistakes in Mark Elliot's code:
public class Pair<L,R> {
private L l;
private R r;
public Pair(L l, R r){
this.l = l;
this.r = r;
}
public L getL(){ return l; }
public R getR(){ return r; }
public void setL(L l){ this.l = l; }
public void setR(R r){ this.r = r; }
}
svn cp /trunk/ /branch/NEW_Branch
If you have some local changes in trunk then use Rsync
to sync changes
rsync -r -v -p --exclude ".svn" /trunk/ /branch/NEW_Branch
Definitely regex:
string CleanPhone(string phone)
{
Regex digitsOnly = new Regex(@"[^\d]");
return digitsOnly.Replace(phone, "");
}
or within a class to avoid re-creating the regex all the time:
private static Regex digitsOnly = new Regex(@"[^\d]");
public static string CleanPhone(string phone)
{
return digitsOnly.Replace(phone, "");
}
Depending on your real-world inputs, you may want some additional logic there to do things like strip out leading 1's (for long distance) or anything trailing an x or X (for extensions).
I am using Vagrant with a Puphpet setup from May 2015 and had this problem. It appears that the configuration that was generated didn't handle Vagrant 1.7.4 (or maybe a bit earlier?) behavior of regenerating ssh keys if it detects an insecure key.
I solved it by adding the following in my Puphpet generated Vagrantfile (local setup) inside the "if File.file?(customKey)" clause:
config.ssh.insert_key = false
Make sure you use the root folder of the JDK. Don't add "\lib" to the end of the path, where tools.jar is physically located. It took me an hour to figure that one out. Also, this post will help show you where Ant is looking for tools.jar:
Why does ANT tell me that JAVA_HOME is wrong when it is not?
I tried the code offered by Xavi Martínez. It worked but not for IE7. The problem is - tabs don't refer to any relevant content.
So, I prefer this code for solving that problem.
function pageLoad() {
$(document).ready(function() {
var tabCookieName = "ui-tabs-1"; //cookie name
var location = $.cookie(tabCookieName); //take tab's href
if (location) {
$('#Tabs a[href="' + location + '"]').tab('show'); //activate tab
}
$('#Tabs a').click(function(e) {
e.preventDefault()
$(this).tab('show')
})
//when content is alredy shown - event activate
$('#Tabs a').on('shown.bs.tab', function(e) {
location = e.target.hash; // take current href
$.cookie(tabCookieName, location, {
path: '/'
}); //write href in cookie
})
});
};
Add the type for the script
<script src="https://maps.googleapis.com/maps/api/js" type="text/javascript"></script>
So the important part is the type text/javascript.
Change
$info=$_POST['id[]'];
to
$info=$_POST['id'];
by adding []
to the end of your form field names, PHP will automatically convert these variables into arrays.
if you are using spring security then you can get the current logged in user by
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String name = auth.getName(); //get logged in username
Why try to reinvent the wheel? There are more lightweight jQuery slideshow solutions out there then you could poke a stick at, and someone has already done the hard work for you and thought about issues that you might run into (cross-browser compatability etc).
jQuery Cycle is one of my favourite light weight libraries.
What you want to achieve could be done in just
jQuery("#slideshow").cycle({
timeout:0, // no autoplay
fx: 'fade', //fade effect, although there are heaps
next: '#next',
prev: '#prev'
});
You can try this example out. A simple C# progaram to convert string to double
class Calculations{
protected double length;
protected double height;
protected double width;
public void get_data(){
this.length = Convert.ToDouble(Console.ReadLine());
this.width = Convert.ToDouble(Console.ReadLine());
this.height = Convert.ToDouble(Console.ReadLine());
}
}
declare | define | initialize |
----------------------------------
extern int a; yes no no
-------------
int a = 2019; yes yes yes
-------------
int a; yes yes no
-------------
Declaration won't allocate memory (the variable must be defined for memory allocation) but the definition will. This is just another simple view on the extern keyword since the other answers are really great.
Generally, I see continue
(and break
) as a warning that the code might use some refactoring, especially if the while
or for
loop declaration isn't immediately in sight. The same is true for return
in the middle of a method, but for a slightly different reason.
As others have already said, continue
moves along to the next iteration of the loop, while break
moves out of the enclosing loop.
These can be maintenance timebombs because there is no immediate link between the continue
/break
and the loop it is continuing/breaking other than context; add an inner loop or move the "guts" of the loop into a separate method and you have a hidden effect of the continue
/break
failing.
IMHO, it's best to use them as a measure of last resort, and then to make sure their use is grouped together tightly at the start or end of the loop so that the next developer can see the "bounds" of the loop in one screen.
continue
, break
, and return
(other than the One True Return at the end of your method) all fall into the general category of "hidden GOTOs". They place loop and function control in unexpected places, which then eventually causes bugs.
Using clearFocus() didn't seem to be working for me either as you found (saw in comments to another answer), but what worked for me in the end was adding:
<LinearLayout
android:id="@+id/my_layout"
android:focusable="true"
android:focusableInTouchMode="true" ...>
to my very top level Layout View (a linear layout). To remove focus from all Buttons/EditTexts etc, you can then just do
LinearLayout myLayout = (LinearLayout) activity.findViewById(R.id.my_layout);
myLayout.requestFocus();
Requesting focus did nothing unless I set the view to be focusable.
It's been a little while since I coded with selenium, but your code looks ok to me. One thing to note is that if the element is not found, but the timeout is passed, I think the code will continue to execute. So you can do something like this:
boolean exists = driver.findElements(By.xpath("//*[@id='someID']")).size() != 0
What does the above boolean return? And are you sure selenium actually navigates to the expected page? (That may sound like a silly question but are you actually watching the pages change... selenium can be run remotely you know...)
I was executing a get request an also want to see just the response and nothing else, seems like magic is done with -silent,-s option.
From the curl man page:
-s, --silent Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.
Below the examples:
curl -s "http://host:8080/some/resource"
curl -silent "http://host:8080/some/resource"
Using custom headers
curl -s -H "Accept: application/json" "http://host:8080/some/resource")
Using POST method with a header
curl -s -X POST -H "Content-Type: application/json" "http://host:8080/some/resource") -d '{ "myBean": {"property": "value"}}'
You can also customize the output for specific values with -w, below the options I use to get just response codes of the curl:
curl -s -o /dev/null -w "%{http_code}" "http://host:8080/some/resource"
a {background-color:transparent !important;}

For example, lets say we want to display only the first 10 items of an array, we could do this using the SlicePipe like so:
<ul>
<li *ngFor="let item of items | slice:0:10">
{{ item }}
</li>
</ul>

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:
A data frame of four rows:
df = pd.DataFrame({'A': [1,2,3,4]})
Now trying to assign a list/array of two elements to it:
df['B'] = [3,4] # or df['B'] = np.array([3,4])
Both errors out:
ValueError: Length of values does not match length of index
Because the data frame has four rows but the list and array has only two elements.
Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:
df['B'] = pd.Series([3,4])
df
# A B
#0 1 3.0
#1 2 4.0
#2 3 NaN # NaN because the value at index 2 and 3 doesn't exist in the Series
#3 4 NaN
For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:
df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))
# A B
#0 1 1.0
#1 2 5.0
#2 7 9.0
#3 8 NaN
Use Enum
's static method, GetNames
. It returns a string[]
, like so:
Enum.GetNames(typeof(DataSourceTypes))
If you want to create a method that does only this for only one type of enum
, and also converts that array to a List
, you can write something like this:
public List<string> GetDataSourceTypes()
{
return Enum.GetNames(typeof(DataSourceTypes)).ToList();
}
You will need Using System.Linq;
at the top of your class to use .ToList()
The reason why Python3 lacks a function for directly getting a ranged list is because the original Python3 designer was quite novice in Python2. He only considered the use of range()
function in a for loop, thus, the list should never need to be expanded. In fact, very often we do need to use the range()
function to produce a list and pass into a function.
Therefore, in this case, Python3 is less convenient as compared to Python2 because:
xrange()
and range()
; range()
and list(range())
Nonetheless, you can still use list expansion in this way:
[*range(N)]
Use Conveyor by Keyoti (extensión de Visual Studio). Extension visual studio
You'll need to type cast it.
long i = 100L;
int k = (int) i;
Bear in mind that a long has a bigger range than an int so you might lose data.
If you are talking about the boxed types, then read the documentation.
Following from Ryan's answer, I think that the interface you are looking for is defined as follows:

You need to use IFS
instead of -d
:
while IFS=, read -r col1 col2
do
echo "I got:$col1|$col2"
done < myfile.csv
Note that for general purpose CSV parsing you should use a specialized tool which can handle quoted fields with internal commas, among other issues that Bash can't handle by itself. Examples of such tools are cvstool
and csvkit
.
The way the operator works is that it gets incremented at the same time, but if it is before a variable, the expression will evaluate with the incremented/decremented variable:
int x = 0; //x is 0
int y = ++x; //x is 1 and y is 1
If it is after the variable the current statement will get executed with the original variable, as if it had not yet been incremented/decremented:
int x = 0; //x is 0
int y = x++; //'y = x' is evaluated with x=0, but x is still incremented. So, x is 1, but y is 0
I agree with dcp in using pre-increment/decrement (++x) unless necessary. Really the only time I use the post-increment/decrement is in while loops or loops of that sort. These loops are the same:
while (x < 5) //evaluates conditional statement
{
//some code
++x; //increments x
}
or
while (x++ < 5) //evaluates conditional statement with x value before increment, and x is incremented
{
//some code
}
You can also do this while indexing arrays and such:
int i = 0;
int[] MyArray = new int[2];
MyArray[i++] = 1234; //sets array at index 0 to '1234' and i is incremented
MyArray[i] = 5678; //sets array at index 1 to '5678'
int temp = MyArray[--i]; //temp is 1234 (becasue of pre-decrement);
Etc, etc...
there's also ndisasm, which has some quirks, but can be more useful if you use nasm. I agree with Michael Mrozek that objdump is probably best.

In my case, even after sign up to Visual Studio account, I cant sign in and the license still expired.

CodeIgniter-Assets is easy to configure repository to have custom header and footer with CodeIgniter I hope this will solve your problem.
I had the same problem but it had nothing to do with annotations. The problem happened while indexing beans in my container (Jboss EAP 6.3). One of my beans could not be indexed because it used Java 8 features an I got this sneaky little warning while deploying:
WARN [org.jboss.as.server.deployment] ... Could not index class ... java.lang.IllegalStateException: Unknown tag! pos=20 poolCount = 133
Then at the injection point I got the error:
Unsatisfied dependencies for type ... with qualifiers @Default
The solution is to update the Java annotations index. download new version of jandex (jandex-1.2.3.Final or newer) then put it into
JBOSS_HOME\modules\system\layers\base\org\jboss\jandex\main and then update reference to the new file in module.xml
NOTE: EAP 6.4.x already have this fixed
The steps you took are not appropriate because the cell you want formatted is not the trigger cell (presumably won't normally be blank). In your case you want formatting to apply to one set of cells according to the status of various other cells. I suggest with data layout as shown in the image (and with thanks to @xQbert for a start on a suitable formula) you select ColumnA and:
HOME > Styles - Conditional Formatting, New Rule..., Use a formula to determine which cells to format and Format values where this formula is true::
=AND(LEN(E1)*LEN(F1)*LEN(G1)*LEN(H1)=0,NOT(ISBLANK(A1)))
Format..., select formatting, OK, OK.

This problem appears when we are using any third party solution, without using the handlers for the cleanup activitiy. For me this was happening for EhCache. We were using EhCache in our project for caching. And often we used to see following error in the logs
SEVERE: The web application [/products] appears to have started a thread named [products_default_cache_configuration] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/products] appears to have started a thread named [Statistics Thread-products_default_cache_configuration-1] but has failed to stop it. This is very likely to create a memory leak.
And we often noticed tomcat failing for OutOfMemory error during development where we used to do backend changes and deploy the application multiple times for reflecting our changes.
This is the fix we did
<listener>
<listener-class>
net.sf.ehcache.constructs.web.ShutdownListener
</listener-class>
</listener>
So point I am trying to make is check the documentation of the third party libraries which you are using. They should be providing some mechanisms to clean up the threads during shutdown. Which you need to use in your application. No need to re-invent the wheel unless its not provided by them. The worst case is to provide your own implementation.

You can send email without Outlook in VBScript using the CDO.Message object. You will need to know the address of your SMTP server to use this:
Set MyEmail=CreateObject("CDO.Message")

MyEmail.From="[email protected]"
MyEmail.To="[email protected]"
MyEmail.TextBody="Testing one two three."
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing")=2

'SMTP Port
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25
MyEmail.Configuration.Fields.Update
MyEmail.Send
set MyEmail=nothing
If your SMTP server requires a username and password then paste these lines in above the MyEmail.Configuration.Fields.Update
line:
'SMTP Auth (For Windows Auth set this to 2)
MyEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate")=1

Use the IP instead:
DROP USER 'root'@'127.0.0.1'; GRANT ALL PRIVILEGES ON . TO 'root'@'%';

Use this code:
// Get current size of heap in bytes
long heapSize = Runtime.getRuntime().totalMemory();
// Get maximum size of heap in bytes. The heap cannot grow beyond this size.// Any attempt will result in an OutOfMemoryException.
long heapMaxSize = Runtime.getRuntime().maxMemory();
// Get amount of free memory within the heap in bytes. This size will increase // after garbage collection and decrease as new objects are created.
long heapFreeSize = Runtime.getRuntime().freeMemory();
It was useful to me to know it.
This also can happen if the device you are trying to run on has some older version of the provisioning profile you are using that points to an old, expired or revoked certificate or a certificate without associated private key. Delete any invalid Provisioning Profiles under your device section in Xcode organizer.
This is how you do it:
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with('persons', $persons)->with('ms', $ms);
}
You can also use compact():
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with(compact('persons', 'ms'));
}
Or do it in one line:
function view($view)
{
return $view
->with('ms', Person::where('name', '=', 'Foo Bar')->first())
->with('persons', Person::order_by('list_order', 'ASC')->get());
}
Or even send it as an array:
function view($view)
{
$ms = Person::where('name', '=', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return $view->with('data', ['ms' => $ms, 'persons' => $persons]));
}
But, in this case, you would have to access them this way:
{{ $data['ms'] }}
To expand a little more, there are two kinds of constructors: instance initializers (.ctor), type initializers (.cctor). Build the code below, and explore the IL code in ildasm.exe. You will notice that the static field 'b' will be initialized through .cctor() whereas the instance field will be initialized through .ctor()
internal sealed class CtorExplorer
{
protected int a = 0;
protected static int b = 0;
}

if (User::where('email', '[email protected]')->first()) {
// It exists
} else {
// It does not exist

Use first()
, not count()
if you only need to check for existence.
first()
is faster because it checks for a single match whereas count()
counts all matches.
I was also facing this issue but in a little different scenario.
Scenario:

param(var)
It looks simple and a stupid mistake here, but due to multiple lines of codes in the actual code, it took some time for me to figure out that the variable name I was using was same as my function name because of which I was getting this error.
Changed function name to something else and it worked.
So, basically, according to what I understood, this error means that you are trying to use an integer as a function or in more simple terms, the called function name is also used as an integer somewhere in the code. So, just try to find out all occurrences of the called function name and look if that is being used as an integer somewhere.
I struggled to find this, so, sharing it here so that someone else may save their time, in case if they get into this issue.
Hope this helps!
Variables in php are case sensitive. Please replace your while loop with following:
while ($rows = mysql_fetch_array($query)):
$name = $rows['Name'];
$address = $rows['Address'];
$email = $rows['Email'];
$subject = $rows['Subject'];
$comment = $rows['Comment']
echo "$name<br>$address<br>$email<br>$subject<br>$comment<br><br>";
endwhile;
For both viewing and modifying values, I would use iterrows()
. In a for loop and by using tuple unpacking (see the example: i, row
), I use the row
for only viewing the value and use i
with the loc
method when I want to modify values. As stated in previous answers, here you should not modify something you are iterating over.
for i, row in df.iterrows():
df_column_A = df.loc[i, 'A']
if df_column_A == 'Old_Value':
df_column_A = 'New_value'
Here the row
in the loop is a copy of that row, and not a view of it. Therefore, you should NOT write something like row['A'] = 'New_Value'
, it will not modify the DataFrame. However, you can use i
and loc
and specify the DataFrame to do the work.
Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:
$('.collapse').on('show.bs.collapse', function () {
$('.collapse.in').collapse('hide');
});
I modified his example to do this here: http://jsfiddle.net/QLfMU/116/
Let's keep it simple. Loved @digitaldreamer 's answer but it might leave the beginners confused. So, I am going to try and simplify it.
The only HTML comment is <!-- -->
It can be used as a single line comment or double, it is really up to the developer.
So, an HTML comment starts with <!--
and ends with -->
. It is really that simple. You should not use any other format, to avoid any compatibility issue even if the comment format is legit or not.

Because the compiler knows the binding at compile time. If you invoke a method on an interface, for example, then the compiler can't know and the binding is resolved at runtime because the actual object having a method invoked on it could possible be one of several. Therefore that is runtime or dynamic binding.
Your invocation is bound to the Animal class at compile time because you've specified the type. If you passed that variable into another method somewhere else, noone would know (apart from you because you wrote it) what actual class it would be. The only clue is the declared type of Animal.

// SET SSL
public static OkClient setSSLFactoryForClient(OkHttpClient client) {
try {
// Create a trust manager that does not validate certificate chains
final TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
}
};
// Install the all-trusting trust manager
final SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
// Create an ssl socket factory with our all-trusting manager
final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
client.setSslSocketFactory(sslSocketFactory);
client.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
} catch (Exception e) {
throw new RuntimeException(e);
}
return new OkClient(client);
}
I will put a small comparison table here (just to have it somewhere):
Servlet is mapped as /test%3F/*
and the application is deployed under /app
.
http://30thh.loc:8480/app/test%3F/a%3F+b;jsessionid=S%3F+ID?p+1=c+d&p+2=e+f#a
Method URL-Decoded Result
----------------------------------------------------
getContextPath() no /app
getLocalAddr() 127.0.0.1
getLocalName() 30thh.loc
getLocalPort() 8480
getMethod() GET
getPathInfo() yes /a?+b
getProtocol() HTTP/1.1
getQueryString() no p+1=c+d&p+2=e+f
getRequestedSessionId() no S%3F+ID
getRequestURI() no /app/test%3F/a%3F+b;jsessionid=S+ID
getRequestURL() no http://30thh.loc:8480/app/test%3F/a%3F+b;jsessionid=S+ID
getScheme() http
getServerName() 30thh.loc
getServerPort() 8480
getServletPath() yes /test?
getParameterNames() yes [p 2, p 1]
getParameter("p 1") yes c d
In the example above the server is running on the localhost:8480
and the name 30thh.loc
was put into OS hosts
file.
Comments
"+" is handled as space only in the query string
Anchor "#a" is not transferred to the server. Only the browser can work with it.
If the url-pattern
in the servlet mapping does not end with *
(for example /test
or *.jsp
), getPathInfo()
returns null
.
If Spring MVC is used
Method getPathInfo()
returns null
.
Method getServletPath()
returns the part between the context path and the session ID. In the example above the value would be /test?/a?+b
Be careful with URL encoded parts of @RequestMapping
and @RequestParam
in Spring. It is buggy (current version 3.2.4) and is usually not working as expected.
The error says that a warning was treated as an error, therefore your problem is a warning message! The object file is then not created because there was an error. So you need to check your warnings and fix them.
In case you don't know how to find them: Open the Error List
(View
> Error List
) and click on Warning
.
On my hosting account this problem was caused by a ModSecurity rule that was set for all accounts automatically. Upon my reporting this problem, their admin quickly removed this rule for my account.
REST is stateless and doesn’t maintain any states between the requests. Client cookies / headers are set to maintain the user state like authentication. Say Client username/password are validated by third part authentication mechanism – 2nd level OTP gerneation etc. Once user get authenticated – headers /cookies comes to rest service end point exposed and we can assume user as auth since user is coming with valid headers/cookies. Now certain info of user like IP is either maintained in the cache and after that if request is coming from same Ip (mac address) for listed resources User is allowed. And cache is maintained for some particular time which get invalidated once time lapses. So either cache can be used or DB entries can be used to persist info b/w the requests.
There's no easy way to do this, but something like this will work:
SELECT ET.TrainingID,
ET.CompletedDate,
ET.Notes
FROM
HR_EmployeeTrainings ET
inner join
(
select TrainingID, Max(CompletedDate) as CompletedDate
FROM HR_EmployeeTrainings
WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID)
GROUP BY AvantiRecID, TrainingID
) ET2
on ET.TrainingID = ET2.TrainingID
and ET.CompletedDate = ET2.CompletedDate
Once you set your Global Jenkins credentials, you can apply this step:
stage('Update GIT') {
steps {
script {
catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE') {
withCredentials([usernamePassword(credentialsId: 'example-secure', passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
def encodedPassword = URLEncoder.encode("$GIT_PASSWORD",'UTF-8')
sh "git config user.email [email protected]"
sh "git config user.name example"
sh "git add ."
sh "git commit -m 'Triggered Build: ${env.BUILD_NUMBER}'"
sh "git push https://${GIT_USERNAME}:${encodedPassword}@github.com/${GIT_USERNAME}/example.git"
}
}
}
}
}
Does anything, easy like that, exists?? THANKS :))
C++ does not store class member names in compiled code, and there's no way to discover (at runtime) which members (variables/methods) class contains. In other words, you cannot iterate through members of a struct. Because there's no such mechanism, you won't be able to automatically create "JSONserialize" for every object.
You can, however, use any json library to serialize objects, BUT you'll have to write serialization/deserialization code yourself for every class. Either that, or you'll have to create serializeable class similar to QVariantMap that'll be used instead of structs for all serializeable objects.
In other words, if you're okay with using specific type for all serializeable objects (or writing serialization routines yourself for every class), it can be done. However, if you want to automatically serialize every possible class, you should forget about it. If this feature is important to you, try another language.
I liked the solution in the earlier post.
I made a mini-class, called it class AlphabeticalHash
. It also has a method called ap
, which accepts one argument, a Hash
, as input: ap variable
. Akin to pp (pp variable
)
But it will (try and) print in alphabetical list (its keys). Dunno if anyone else wants to use this, it's available as a gem, you can install it as such: gem install alphabetical_hash
For me, this is simple enough. If others need more functionality, let me know, I'll include it into the gem.
EDIT: Credit goes to Peter, who gave me the idea. :)

I guess you are asking why is 1388516401 equal to 2014-01-01...?
There is an historical reason for that. There is a 32-bit integer variable, called time_t
, that keeps the count of the time elapsed since 1970-01-01 00:00:00. Its value expresses time in seconds. This means that in 2014-01-01 00:00:01 time_t
will be equal to 1388516401.
This leads us for sure to another interesting fact... In 2038-01-19 03:14:07 time_t
will reach 2147485547, the maximum value for a 32-bit number. Ever heard about John Titor and the Year 2038 problem? :D
It can depend, especially on whether your file will have the same number of items on each row or not. If it will, then you probably want a 2D matrix class of some sort, usually something like this:
class array2D {
std::vector<double> data;
size_t columns;
public:
array2D(size_t x, size_t y) : columns(x), data(x*y) {}
double &operator(size_t x, size_t y) {
return data[y*columns+x];
}
};
Note that as it's written, this assumes you know the size you'll need up-front. That can be avoided, but the code gets a little larger and more complex.
In any case, to read the numbers and maintain the original structure, you'd typically read a line at a time into a string, then use a stringstream to read numbers from the line. This lets you store the data from each line into a separate row in your array.
If you don't know the size ahead of time or (especially) if different rows might not all contain the same number of numbers:
11 12 13
23 34 56 78
You might want to use a std::vector<std::vector<double> >
instead. This does impose some overhead, but if different rows may have different sizes, it's an easy way to do the job.
std::vector<std::vector<double> > numbers;
std::string temp;
while (std::getline(infile, temp)) {
std::istringstream buffer(temp);
std::vector<double> line((std::istream_iterator<double>(buffer)),
std::istream_iterator<double>());
numbers.push_back(line);
}
...or, with a modern (C++11) compiler, you can use brackets for line
's initialization:
std::vector<double> line{std::istream_iterator<double>(buffer),
std::istream_iterator<double>()};
I don't know whether this has appeared obvious here. I would like to point out that as far as client-side (browser) JavaScript is concerned, you can add type="module"
to both external as well as internal js scripts.
Say, you have a file 'module.js':
var a = 10;
export {a};
You can use it in an external script, in which you do the import, eg.:
<!DOCTYPE html><html><body>
<script type="module" src="test.js"></script><!-- Here use type="module" rather than type="text/javascript" -->
</body></html>
test.js:
import {a} from "./module.js";
alert(a);
You can also use it in an internal script, eg.:
<!DOCTYPE html><html><body>
<script type="module">
import {a} from "./module.js";
alert(a);
</script>
</body></html>
It is worthwhile mentioning that for relative paths, you must not omit the "./" characters, ie.:
import {a} from "module.js"; // this won't work
When you use : scene.remove(object); The object is removed from the scene, but the collision with it is still enabled !
To remove also the collsion with the object, you can use that (for an array) : objectsArray.splice(i, 1);
Example :
for (var i = 0; i < objectsArray.length; i++) {
//::: each object ::://
var object = objectsArray[i];
//::: remove all objects from the scene ::://
scene.remove(object);
//::: remove all objects from the array ::://
objectsArray.splice(i, 1);
}
Below code works for me
public static void sftpsript(String filepath) {
try {
String user ="demouser"; // username for remote host
String password ="demo123"; // password of the remote host
String host = "demo.net"; // remote host address
JSch jsch = new JSch();
Session session = jsch.getSession(user, host);
session.setPassword(password);
session.connect();
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();
sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
sftpChannel.disconnect();
session.disconnect();
}catch(Exception ex){
ex.printStackTrace();
}
}
OR using StrictHostKeyChecking as "NO" (security consequences)
public static void sftpsript(String filepath) {
try {
String user ="demouser"; // username for remote host
String password ="demo123"; // password of the remote host
String host = "demo.net"; // remote host address
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, 22);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);;
session.setPassword(password);
System.out.println("user=="+user+"\n host=="+host);
session.connect();
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();
sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
sftpChannel.disconnect();
session.disconnect();
}catch(Exception ex){
ex.printStackTrace();
}
}
My scenario is little different, but the intent is same i would like to know when the parent window hosting my user control is closing/closed as The view(i.e my usercontrol) should invoke the presenters oncloseView to execute some functionality and perform clean up. ( well we are implementing a MVP pattern on a WPF PRISM application).
I just figured that in the Loaded event of the usercontrol, i can hook up my ParentWindowClosing method to the Parent windows Closing event. This way my Usercontrol can be aware when the Parent window is being closed and act accordingly!

"an object" of what type?
You can certainly assign NULL
(and nullptr
) to objects of pointer types, and it is implementation defined if you can assign NULL
to objects of arithmetic types.
If you mean objects of some class type, the answer is NO (excepting classes that have operator=
accepting pointer or arithmetic types)
"empty" is more plausible, as many types have both copy assignment and default construction (often implicitly). To see if an existing object is like a default constructed one, you will also need an appropriate bool operator==
Your error
InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable
appears because you must call setRequestHeader
after calling open
. Simply move your setRequestHeader
line below your open
line (but before send
):
xmlhttp.open("POST", url);
xmlhttp.setRequestHeader("x-filename", photoId);
xmlhttp.send(formData);

If I get you right, you want something that seems to be the opposite of what is desired normally: you want a horizontal layout for small screens and vertically stacked elements on large screens. You may achieve this in a way like this:
<div class="container">
<div class="row">
<div class="hidden-md hidden-lg col-xs-3 col-xs-offset-6">a</div>
<div class="hidden-md hidden-lg col-xs-3">b</div>
</div>
<div class="row">
<div class="hidden-xs hidden-sm">c</div>
</div>
</div>
On small screens, i.e. xs and sm, this generates one row with two columns with an offset of 6. On larger screens, i.e. md and lg, it generates two vertically stacked elements in full width (12 columns).
I'm going to offer an answer that conflicts a bit with some of the popular answers here. In my opinion, concurrency is a general term that includes parallelism. Concurrency applies to any situation where distinct tasks or units of work overlap in time. Parallelism applies more specifically to situations where distinct units of work are evaluated/executed at the same physical time. The raison d'etre of parallelism is speeding up software that can benefit from multiple physical compute resources. The other major concept that fits under concurrency is interactivity. Interactivity applies when the overlapping of tasks is observable from the outside world. The raison d'etre of interactivity is making software that is responsive to real-world entities like users, network peers, hardware peripherals, etc.
Parallelism and interactivity are almost entirely independent dimension of concurrency. For a particular project developers might care about either, both or neither. They tend to get conflated, not least because the abomination that is threads gives a reasonably convenient primitive to do both.
A little more detail about parallelism:
Parallelism exists at very small scales (e.g. instruction-level parallelism in processors), medium scales (e.g. multicore processors) and large scales (e.g. high-performance computing clusters). Pressure on software developers to expose more thread-level parallelism has increased in recent years, because of the growth of multicore processors. Parallelism is intimately connected to the notion of dependence. Dependences limit the extent to which parallelism can be achieved; two tasks cannot be executed in parallel if one depends on the other (Ignoring speculation).
There are lots of patterns and frameworks that programmers use to express parallelism: pipelines, task pools, aggregate operations on data structures ("parallel arrays").
A little more detail about interactivity:
The most basic and common way to do interactivity is with events (i.e. an event loop and handlers/callbacks). For simple tasks events are great. Trying to do more complex tasks with events gets into stack ripping (a.k.a. callback hell; a.k.a. control inversion). When you get fed up with events you can try more exotic things like generators, coroutines (a.k.a. Async/Await), or cooperative threads.
For the love of reliable software, please don't use threads if what you're going for is interactivity.
Curmudgeonliness
I dislike Rob Pike's "concurrency is not parallelism; it's better" slogan. Concurrency is neither better nor worse than parallelism. Concurrency includes interactivity which cannot be compared in a better/worse sort of way with parallelism. It's like saying "control flow is better than data".

You should use abstract class to initialize a property. You can't inititalize in Inteface .
You can also use below code:
int ss = nDur%60;
nDur = nDur/60;
int mm = nDur%60;
int hh = nDur/60;
For generating icons for your Xcode projects, I'd suggest you consider using SquareIcon. I believe that it makes creating app icon sets for Apple platforms very easy. Just to let you know, this is my own app.
You can drop in a generic image file of your icon (like a PNG
or JPG
) and generate a .appiconset
file which you can put in your Xcode project's asset catalog. This removes the requirement of manually resizing a bunch of images.
Or add styles inline:
<p style="font-size:18px">Paragraph 1</p>
<p style="font-size:16px">Paragraph 2</p>
jQuery implements this quite elegantly. If you look at the source for jQuery's offset
, you'll find this is basically how it's implemented:
var rect = elem.getBoundingClientRect();
var win = elem.ownerDocument.defaultView;
return {
top: rect.top + win.pageYOffset,
left: rect.left + win.pageXOffset
};
We'll never convince people to leave IE6 if we keep striving to deliver quality websites to those users.
Only IE7+ understood "position: fixed".
https://developer.mozilla.org/en-US/docs/Web/CSS/position
So you're out of luck for IE6. To get the footer semi-sticky try this:
.main {
min-height: 100%;
margin-bottom: -60px;
}
.footer {
height: 60px;
}
You could also use an iFrame maybe.
This will keep the footer from 'lifting off' from the bottom of the page. If you have more than one page of content then it will push down out of site.
On a philosophical note, I'd rather point IE6 users to http://browsehappy.com/ and spend the time I save hacking for IE6 on something else.

Because timedelta objects can be passed seconds, milliseconds, days, etc... so you need to specify what are you passing in (this is why you use the explicit key). Typecasting to int
is superfluous as they could also accept floats.
and why does the string casting works so nicely that I get HH:MM:SS ?
It's not the typecasting that formats, is the internal __str__
method of the object. In fact you will achieve the same result if you write:
print datetime.timedelta(seconds=int(uptime))
Use conditional formatting instead of VBA to highlight errors.
Using a VBA loop like the one you posted will take a long time to process
the statement If cell.Value = "#N/A" Then
will never work. If you insist on using VBA to highlight errors, try this instead.
Sub ColorCells()
Dim Data As Range
Dim cell As Range
Set currentsheet = ActiveWorkbook.Sheets("Comparison")
Set Data = currentsheet.Range("A2:AW1048576")
For Each cell In Data
If IsError(cell.Value) Then
cell.Interior.ColorIndex = 3
End If
Next
End Sub
Be prepared for a long wait, since the procedure loops through 51 million cells
There are more efficient ways to achieve what you want to do. Update your question if you have a change of mind.
If using a StackTraceElement, use:
String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);
System.out.println(simpleClassName);
tl;dr: Generic Pattern Counter
// THIS IS WHAT YOU NEED
const count = (str) => {
const re = /YOUR_PATTERN_HERE/g
return ((str || '').match(re) || []).length
}
For those that arrived here looking for a generic way to count the number of occurrences of a regex pattern in a string, and don't want it to fail if there are zero occurrences, this code is what you need. Here's a demonstration:
/*_x000D_
* Example_x000D_
*/_x000D_
_x000D_
const count = (str) => {_x000D_
const re = /[a-z]{3}/g_x000D_
return ((str || '').match(re) || []).length_x000D_
}_x000D_
_x000D_
const str1 = 'abc, def, ghi'_x000D_
const str2 = 'ABC, DEF, GHI'_x000D_
_x000D_
console.log(`'${str1}' has ${count(str1)} occurrences of pattern '/[a-z]{3}/g'`)_x000D_
console.log(`'${str2}' has ${count(str2)} occurrences of pattern '/[a-z]{3}/g'`)
_x000D_
Original Answer
The problem with your initial code is that you are missing the global identifier:
>>> 'hi there how are you'.match(/\s/g).length;
4
Without the g
part of the regex it will only match the first occurrence and stop there.
Also note that your regex will count successive spaces twice:
>>> 'hi there'.match(/\s/g).length;
2
If that is not desirable, you could do this:
>>> 'hi there'.match(/\s+/g).length;

The angular way is shown in the angular docs :)
https://docs.angularjs.org/api/ng/directive/ngReadonly
Here is the example they use:
<body>
Check me to make text readonly: <input type="checkbox" ng-model="checked"><br/>
<input type="text" ng-readonly="checked" value="I'm Angular"/>
</body>
Basically the angular way is to create a model object that will hold whether or not the input should be readonly and then set that model object accordingly. The beauty of angular is that most of the time you don't need to do any dom manipulation. You just have angular render the view they way your model is set (let angular do the dom manipulation for you and keep your code clean).
So basically in your case you would want to do something like below or check out this working example.
<button ng-click="isInput1ReadOnly = !isInput1ReadOnly">Click Me</button>
<input type="text" ng-readonly="isInput1ReadOnly" value="Angular Rules!"/>
This is what I found while running batch files in parallel (multiple instances of the same bat file at the same time with different input parameters) :
Lets say that you have an exe file that performs a long task called LongRunningTask.exe
If you call the exe directly from the bat file, only the first call to the LongRunningTask will succed, while the rest will get an OS error "File is already in use by the process"
If you use this command:
start /B /WAIT "" "LongRunningTask.exe" "parameters"
You will be able to run multiple instances of the bat and exe, while still waiting for the task to finish before the bat continues executing the remaining commands. The /B option is to avoid creating another window, the empty quotes are needed in order to the command to work, see the reference below.
Note that if you don´t use the /WAIT in the start, the LongRunningTask will be executed at the same time than the remaining commands in the batch file, so it might create problems if one of these commands requires the output of the LongRunningTask
Resuming :
This can´t run in parallel :
This will run in parallel and will be ok as far as there are no data dependencies between the output of the command and the rest of the bat file :
This will run in parallel and wait for the task to finish, so you can use the output :
Reference for the start command : How can I run a program from a batch file without leaving the console open after the program start?
Try below Alphanumeric regex
"^[a-zA-Z0-9]*$"
^ - Start of string
[a-zA-Z0-9]* - multiple characters to include
$ - End of string

Some of this may be due to the OS your server is running. I recently did a migration to a new hosting environment running Ubuntu. Adding this alias alias composer="/path/to/your/composer"
to .bashrc or .bash_aliases didn't work at first because of two reasons:
The server was running csh, not bash, by default. To check if this is an issue in your case, run echo $0
. If the what is returned is -csh
you will want to change it to bash, since some processes run by Composer will fail using csh/tcsh.
To change it, first check if bash is available on your server by running cat /etc/shells
. If, in the list returned, you see bin/bash
, you can change the default to bash by running chsh -s /bin/csh
.
Now, at this point, you should be able to run Composer, but normally, on Ubuntu, you will have to load the script at every session by sourcing your Bash scripts by running source ~/.bashrc
or source ~/.bash_profile
. This is because, in most cases, Ubuntu won't load your Bash script, since it loads .profile
as the default script.
To load your Bash scripts when you open a session, try adding this to your .profile (this is if your Bash script is .bashrc—modify accordingly if .bash_profile or other):
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi
To test, close your session and reload. If it's working properly, running composer -v
or which composer
should behave as expected.

Business Intelligence Development Studio is Microsoft Visual Studio 2008 with additional project types that are specific to SQL Server business intelligence. Business Intelligence Development Studio is the primary environment that you will use to develop business solutions that include Analysis Services, Integration Services, and Reporting Services projects. Each project type supplies templates for creating the objects required for business intelligence solutions, and provides a variety of designers, tools, and wizards to work with the objects.
If you already have Visual Studio installed, the new project types will be installed along with SQL Server.
Your line:
img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.
Try
cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
You can use ES6 spread on previous values in the object to avoid overwrite
this.setState({
abc: {
...this.state.abc,
xyz: 'new value'
}
});
If you get this issue, then either
Here's an easy jQuery way:
var el = $('#yourid .yourclass');
el.html(el.html().replace(/Old Text/ig, "New Text"));
HashMap don't allow duplicate keys,but since it's not thread safe,it might occur duplicate keys. eg:
while (true) {
final HashMap<Object, Object> map = new HashMap<Object, Object>(2);
map.put("runTimeType", 1);
map.put("title", 2);
map.put("params", 3);
final AtomicInteger invokeCounter = new AtomicInteger();
for (int i = 0; i < 100; i++) {
new Thread(new Runnable() {
@Override
public void run() {
map.put("formType", invokeCounter.incrementAndGet());
}
}).start();
}
while (invokeCounter.intValue() != 100) {
Thread.sleep(10);
}
if (map.size() > 4) {
// this means you insert two or more formType key to the map
System.out.println( JSONObject.fromObject(map));
}
}
