You could go a step further and break into the puppet code using a breakpoint.
http://logicminds.github.io/blog/2017/04/25/break-into-your-puppet-code/
This would only work with puppet apply or using a rspec test. Or you can manually type your code into the debugger console. Note: puppet still needs to know where your module code is at if you haven't set already.
gem install puppet puppet-debugger
puppet module install nwops/debug
cat > test.pp <<'EOF'
$var1 = 'test'
debug::break()
EOF
Should show something like.
puppet apply test.pp
From file: test.pp
1: $var1 = 'test'
2: # add 'debug::break()' where you want to stop in your code
=> 3: debug::break()
1:>> $var1
=> "test"
2:>>
You can use a case in this case, to separate versions one example is using FACT os (which returns the version etc of your system... the command facter will return the details:
root@sytem# facter -p os
{"name"=>"CentOS", "family"=>"RedHat", "release"=>{"major"=>"7", "minor"=>"0", "full"=>"7.0.1406"}}
#we capture release hash
$curr_os = $os['release']
case $curr_os['major'] {
'7': { .... something }
*: {something}
}
That is an fast example, Might have typos, or not exactly working. But using system facts you can see what happens.
The OS fact provides you 3 main variables: name, family, release... Under release you have a small dictionary with more information about your os! combining these you can create cases to meet your targets.
Permission to view log files is granted to users being in the group adm.
To add a user to this group on the command line issue:
sudo usermod -aG adm <USER>
No, filter does not scan the whole stream. It's an intermediate operation, which returns a lazy stream (actually all intermediate operations return a lazy stream). To convince you, you can simply do the following test:
List<Integer> list = Arrays.asList(1, 10, 3, 7, 5);
int a = list.stream()
.peek(num -> System.out.println("will filter " + num))
.filter(x -> x > 5)
.findFirst()
.get();
System.out.println(a);
Which outputs:
will filter 1
will filter 10
10
You see that only the two first elements of the stream are actually processed.
So you can go with your approach which is perfectly fine.
If you're attempting to share code between two different project types (I.e.: desktop project and a mobile project), you may look into the shared solutions folder. I have to do that for my current project as the mobile and desktop projects both require identical classes that are only in 1 file. If you go this route, any of the projects that have the file linked can make changes to it and all of the projects will be rebuilt against those changes.
Some files where missing at your local repository. Usually under ${user.home}/.m2/repository/
Neets answer solves the problem. However if you dont want do download all the dependencies to your local repository again you could add the missing dependency to a project of yours and compile it.
Use the maven repository website to find the dependency. In your case http://mvnrepository.com/artifact/org.apache.maven.plugins/maven-resources-plugin/2.5 was missing.
Copy the listed XML to the pom.xml file of your project. In this case
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
</dependency>
Run mvn compile
in the root folder of the pom.xml. Maven will download all missing dependencies. After the download you can remove the added dependency.
Now you should be able to import the maven project or update the project without the error.
The arrange
function in the plyr
package makes it easy to sort by multiple columns. For example, to sort DF
by ID
first and then decreasing by num
, you can write
plyr::arrange(DF, ID, desc(num))
A couple of issues
>
in -exec
without something like bash -c '... > ...'
. Though the >
will overwrite the file, so you want to redirect the entire find
anyway rather than each -exec
. +30
is older
than 30 days, -30
would be modified in last 30 days.-exec
really isn't needed, you could list everything with various -printf
options. Something like below should work
find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt
Example with -printf
find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt
This will list files in format "permissions owner group time date filename". -printf
is generally preferable to -exec
in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec
. Depending on the version of find
, you may also be able to use -ls
, which has a similar format to above.
You probably want egrep. Try:
egrep '^[d-]rwx.*[0-9]$' usrLog.txt

Use "here document":
sqlplus -s user/pass <<+EOF

Since you have not defined what an empty file is. Some might consider a file with just blank lines also an empty file. So if you want to check if your file contains only blank lines (any whitespace character, '\r', '\n', '\t'), you can follow the example below:
Python3
import re
def whitespace_only(file):
content = open(file, 'r').read()
if re.search(r'^\s*$', content):
return True
Explain: the example above uses regular expression (regex) to match the content (content
) of the file.
Specifically: for regex of: ^\s*$
as a whole means if the file contains only blank lines and/or blank spaces.
- ^
asserts position at start of a line
- \s
matches any whitespace character (equal to [\r\n\t\f\v ])
- *
Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
- $
asserts position at the end of a line
Perhaps you should check NLS_DATE_FORMAT
and use the date string conforming the format.
Or you can use to_date
function within the INSERT
statement, like the following:
insert into visit
values(123456,
to_date('19-JUN-13', 'dd-mon-yy'),
to_date('13-AUG-13 12:56 A.M.', 'dd-mon-yyyy hh:mi A.M.'));
Additionally, Oracle DATE
stores date and time information together.
You could query the sys.tables database view to get out the names of the tables, and then use this query to build yourself another query to do the update on the back of that. For instance:
select 'select * from '+name from sys.tables
will give you a script that will run a select * against all the tables in the system catalog, you could alter the string in the select clause to do your update, as long as you know the column name is the same on all the tables you wish to update, so your script would look something like:
select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables
You could also then predicate on the tables query to only include tables that have a name in a certain format, or are in a subset you want to create the update script for.
I try to understand the famous sentence in my way: "Python dose not care an object is a real duck or not. All it cares is whether the object, first 'quack', second 'like a duck'."
There is a good website. http://www.voidspace.org.uk/python/articles/duck_typing.shtml#id14
The author pointed that duck typing let you create your own classes that have their own internal data structure - but are accessed using normal Python syntax.
Here is a simple programe to capture a image from using laptop default camera.I hope that this will be very easy method for all.

You just missed an extra pair of brackets for the "OR" symbol. The following should do the trick:
([0-9]+)\s+((\bseconds\b)|(\bminutes\b))
Without those you were either matching a number followed by seconds OR just the word minutes
iOS12 Swift 4 and Swift 5
If you just want to check the connection, and your lowest target is iOS12, then you can use NWPathMonitor
import Network
It needs a little setup with some properties.
let internetMonitor = NWPathMonitor()
let internetQueue = DispatchQueue(label: "InternetMonitor")
private var hasConnectionPath = false
I created a function to get it going. You can do this on view did load or anywhere else. I put a guard in so you can call it all you want to get it going.
func startInternetTracking() {
// only fires once
guard internetMonitor.pathUpdateHandler == nil else {
return
}
internetMonitor.pathUpdateHandler = { update in
if update.status == .satisfied {
print("Internet connection on.")
self.hasConnectionPath = true
} else {
print("no internet connection.")
self.hasConnectionPath = false
}
}
internetMonitor.start(queue: internetQueue)
}
/// will tell you if the device has an Internet connection
/// - Returns: true if there is some kind of connection
func hasInternet() -> Bool {
return hasConnectionPath
}
Now you can just call the helper function hasInternet()
to see if you have one. It updates in real time. See Apple documentation for NWPathMonitor
. It has lots more functionality like cancel()
if you need to stop tracking the connection, type of internet you are looking for, etc.

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.
No, that's not true. The session-timeout
configures a per session timeout in case of inactivity.
Are these methods equivalent? Should I favour the web.xml config?
The setting in the web.xml is global, it applies to all sessions of a given context. Programatically, you can change this for a particular session.
6.5.5 Multiplicative operators
...
6 When integers are divided, the result of the/
operator is the algebraic quotient with any fractional part discarded.105) If the quotienta/b
is representable, the expression(a/b)*b + a%b
shall equala
; otherwise, the behavior of botha/b
anda%b
is unde?ned.
105) This is often called ‘‘truncation toward zero’’.
Dividing an integer by an integer gives an integer result. 1/2 yields 0; assigning this result to a floating-point variable gives 0.0. To get a floating-point result, at least one of the operands must be a floating-point type. b = a / 350.0f;
should give you the result you want.
I made my own version of the subclass of 'UITextView'. I liked Sam Soffes's idea of using the notifications, but I didn't liked the drawRect: overwrite. Seems overkill to me. I think I made a very clean implementation.
You can look at my subclass here. A demo project is also included.

Click the little green add icon, type m and hit ok. Everything in this window automatically has -l applied to it since it is a library.
Just use /\s+/ against '' as a splitter. In this case all "extra" blanks were removed. Usually this particular behaviour is required. So, in you case it will be:
my $line = "file1.gz file1.gz file3.gz";
my @abc = split(/\s+/, $line);
After importing stored procedure, you can create object of stored procedure pass the parameter like function
using (var entity = new FunctionsContext())
{
var DBdata = entity.GetFunctionByID(5).ToList<Functions>();
}
or you can also use SqlQuery
using (var entity = new FunctionsContext())
{
var Parameter = new SqlParameter {
ParameterName = "FunctionId",
Value = 5
};
var DBdata = entity.Database.SqlQuery<Course>("exec GetFunctionByID @FunctionId ", Parameter).ToList<Functions>();
}
The characteristics of sets in Python are that the data items in a set are unordered and duplicates are not allowed. If you try to add a data item to a set that already contains the data item, Python simply ignores it.
>>> l = ['a', 'a', 'bb', 'b', 'c', 'c', '10', '10', '8','8', 10, 10, 6, 10, 11.2, 11.2, 11, 11]
>>> distinct_l = set(l)
>>> print(distinct_l)
set(['a', '10', 'c', 'b', 6, 'bb', 10, 11, 11.2, '8'])

Try to browse the service in the browser and in the Https mode, if it is not brow-sable then it proves the reason for this error. Now, to solve this error you need to check :
Are you sure? This forum thread suggests it might be your watch window. Try outputting the string to a MsgBox, which can display a maximum of 1024 characters:
MsgBox RunMacros
list.sort((a, b) => (a.attr > b.attr) - (a.attr < b.attr))
Or
list.sort((a, b) => +(a.attr > b.attr) || -(a.attr < b.attr))
Casting a boolean value to a number yields the following:
true
-> 1
false
-> 0
Consider three possible patterns:
(x > y) - (y < x)
-> 1 - 0
-> 1
(x > y) - (y < x)
-> 0 - 0
-> 0
(x > y) - (y < x)
-> 0 - 1
-> -1
(Alternative)
+(x > y) || -(x < y)
-> 1 || 0
-> 1
+(x > y) || -(x < y)
-> 0 || 0
-> 0
+(x > y) || -(x < y)
-> 0 || -1
-> -1
So these logics are equivalent to typical sort comparator functions.
if (x == y) {
return 0;
}
return x > y ? 1 : -1;

To ignore this error for one instance only, add the tools:ignore="ProtectedPermissions"
attribute to your permission declaration. Here is an example:
<uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE"
tools:ignore="ProtectedPermissions" />
You have to add tools
namespace in the manifest root element
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
Range<Long> timeRange = Range.create(model.getFrom(), model.getTo());
if(timeRange.contains(systemtime)){
Toast.makeText(context, "green!!", Toast.LENGTH_SHORT).show();
}
Most of the MVC helper methods have a XXXFor variant. They are intended to be used in conjunction with a concrete model class. The idea is to allow the helper to derive the appropriate "name" attribute for the form-input control based on the property you specify in the lambda. This means that you get to eliminate "magic strings" that you would otherwise have to employ to correlate the model properties with your views. For example:
Html.Hidden("Name", "Value")
Will result in:
<input id="Name" name="Name" type="hidden" value="Value">
In your controller, you might have an action like:
[HttpPost]
public ActionResult MyAction(MyModel model)
{
}
And a model like:
public class MyModel
{
public string Name { get; set; }
}
The raw Html.Hidden
we used above will get correlated to the Name
property in the model. However, it's somewhat distasteful that the value "Name" for the property must be specified using a string ("Name"). If you rename the Name
property on the Model, your code will break and the error will be somewhat difficult to figure out. On the other hand, if you use HiddenFor
, you get protected from that:
Html.HiddenFor(x => x.Name, "Value");
Now, if you rename the Name
property, you will get an explicit runtime error indicating that the property can't be found. In addition, you get other benefits of static analysis, such as getting a drop-down of the members after typing x.
.
All posted data will be in the $_POST superglobal.
This is now part of ES6, thus is standardized, and is also documented on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator
It's very convenient to use and makes a lot of sense alongside object destructuring.
The one remaining advantage listed above is the dynamic capabilities of Object.assign(), however this is as easy as spreading the array inside of a literal object. In the compiled babel output it uses exactly what is demonstrated with Object.assign()
So the correct answer would be to use object spread since it is now standardized, widely used (see react, redux, etc), is easy to use, and has all the features of Object.assign()
I had exactly the same error when running tests with PyCharm. I've fixed it by explicitly setting DJANGO_SETTINGS_MODULE
environment variable. If you're using PyCharm, just hit Edit Configurations button and choose Environment Variables.
Set the variable to your_project_name.settings
and that should fix the thing.
It seems like this error occurs, because PyCharm runs tests with its own manage.py
.
I don't see an export or save as option.
I filtered out all the unwanted requests using -.css -.js -.woff
then right clicked on one of the requests then Copy > Copy all as HAR
Then pasted the content into a text editor and saved it.
This also happened to me but using Dynamic Features. I already had Java 8 compatibility enabled in the app module but I had to add this compatibility lines to the Dynamic Feature module and then it worked.
When you echo $array;
, the result is Array
, result[0]
then represents the first character in Array
which is A
.
One way to handle this problem would be like this:
ajax.php
<?php
$array = array(1,2,3,4,5,6);
foreach($array as $a)
echo $a.",";
?>
jquery code
$(function(){ /* short for $(document).ready(function(){ */
$('#prev').click(function(){
$.ajax({type: 'POST',
url: 'ajax.php',
data: 'id=testdata',
cache: false,
success: function(data){
var tmp = data.split(",");
$('#content1').html(tmp[0]);
}
});
});
});
You should look at Computed Properties
In your code sample, perimeter
is a property not backed up by a class variable, instead its value is computed using the get
method and stored via the set
method - usually referred to as getter and setter.
When you use that property like this:
var cp = myClass.perimeter
you are invoking the code contained in the get
code block, and when you use it like this:
myClass.perimeter = 5.0
you are invoking the code contained in the set
code block, where newValue
is automatically filled with the value provided at the right of the assignment operator.
Computed properties can be readwrite if both a getter and a setter are specified, or readonly if the getter only is specified.

TL;DR: To access newer versions of mysql/mariadb after as the root user, after a new install, you need to be in a root shell (ie sudo mysql -u root
, or mysql -u root
inside a shell started by su -
or sudo -i
first)
Having just done the same upgrade, on Ubuntu, I had the same issue.
What was odd was that
sudo /usr/bin/mysql_secure_installation
Would accept my password, and allow me to set it, but I couldn't log in as root
via the mysql
client
I had to start mariadb with
sudo mysqld_safe --skip-grant-tables
to get access as root, whilst all the other users could still access fine.
Looking at the mysql.user
table I noticed for root the plugin
column is set to unix_socket
whereas all other users it is set to 'mysql_native_password'. A quick look at this page: https://mariadb.com/kb/en/mariadb/unix_socket-authentication-plugin/ explains that the Unix Socket enables logging in by matching uid
of the process running the client with that of the user in the mysql.user
table. In other words to access mariadb as root
you have to be logged in as root.
Sure enough restarting my mariadb daemon with authentication required I can login as root with
sudo mysql -u root -p
or
sudo su -
mysql -u root -p
Having done this I thought about how to access without having to do the sudo, which is just a matter of running these mysql queries
GRANT ALL PRIVILEGES on *.* to 'root'@'localhost' IDENTIFIED BY '<password>';
FLUSH PRIVILEGES;
(replacing <password>
with your desired mysql root password). This enabled password logins for the root user.
Alternatively running the mysql query:
UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE user = 'root' AND plugin = 'unix_socket';
FLUSH PRIVILEGES;
Will change the root account to use password login without changing the password, but this may leave you with a mysql/mariadb install with no root password on it.
After either of these you need to restarting mysql/mariadb:
sudo service mysql restart
And voila I had access from my personal account via mysql -u root -p
PLEASE NOTE THAT DOING THIS IS REDUCING SECURITY Presumably the MariaDB developers have opted to have root access work like this for a good reason.
Thinking about it I'm quite happy to have to sudo mysql -u root -p
so I'm switching back to that, but I thought I'd post my solution as I couldn't find one elsewhere.
window.location = url;
'url' is the web url you want to redirect.
MessageBox doesn't exist in ASP.NET. If you need functionality in the browser, like showing a message box, then you need to opt for javascript. ASP.NET provides you with means to inject javascript which gets rendered and executed when the html sent to the browser's loaded and displayed. You can use the following code in the Page_Load for example:
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the startup script is already registered.
if (!cs.IsStartupScriptRegistered(cstype, "PopupScript"))
{
String cstext = "alert('Hello World');";
cs.RegisterStartupScript(cstype, "PopupScript", cstext, true);
}
This sample's taken from MSDN.
Here's my two solutions for this
1. Store in json files
Just make a json file and get in your component by $http.get()
method. If I was need this very low then it's good and quick.
2. Store by using data services
If you want to store and use in all components or having large usage then it's better to use data service. Like this :
Just create static folder inside src/app
folder.
Create a file named as fuels.ts
into static folder. You can store other static files here also. Let define your data like this. Assuming you having fuels data.
__
export const Fuels {
Fuel: [
{ "id": 1, "type": "A" },
{ "id": 2, "type": "B" },
{ "id": 3, "type": "C" },
{ "id": 4, "type": "D" },
];
}
__
import { Injectable } from "@angular/core";
import { Fuels } from "./static/fuels";
@Injectable()
export class StaticService {
constructor() { }
getFuelData(): Fuels[] {
return Fuels;
}
}`
just import in app.module.ts file like this and change in providers
import { StaticService } from './static.services';
providers: [StaticService]
Now use this as StaticService
in any module.
That's All.
Just to be sure I have benchmarked grep and map solutions, first searching for indexes of matched elements (those to remove) and then directly removing the elements by grep without searching for the indexes. I appears that the first solution proposed by Sam when asking his question was already the fastest.
use Benchmark;
my @A=qw(A B C A D E A F G H A I J K L A M N);
my @M1; my @G; my @M2;
my @Ashrunk;
timethese( 1000000, {
'map1' => sub {
my $i=0;
@M1 = map { $i++; $_ eq 'A' ? $i-1 : ();} @A;
},
'map2' => sub {
my $i=0;
@M2 = map { $A[$_] eq 'A' ? $_ : () ;} 0..$#A;
},
'grep' => sub {
@G = grep { $A[$_] eq 'A' } 0..$#A;
},
'grem' => sub {
@Ashrunk = grep { $_ ne 'A' } @A;
},
});
The result is:

As shown by elapsed times, it's useless to try to implement a remove function using either grep or map defined indexes. Just grep-remove directly.
Before testing I was thinking "map1" would be the most efficient... I should more often rely on Benchmark I guess. ;-)
DateTime dt1 = DateTime.ParseExact([YourDate], "dd-MM-yyyy HH:mm:ss",
CultureInfo.InvariantCulture);
Note the use of HH (24-hour clock) rather than hh (12-hour clock), and the use of InvariantCulture because some cultures use separators other than slash.
For example, if the culture is de-DE, the format "dd/MM/yyyy" would expect period as a separator (31.01.2011).
You can convert list in string with elements seperated by space and split it based on number/char to be searched..
Will be clean and fast for large list..
>>>L = [2,1,1,2,1,3]
>>>strL = " ".join(str(x) for x in L)
>>>strL
2 1 1 2 1 3
>>>count=len(strL.split(" 1"))-1
>>>count
3
It packs arguments passed to the function into list
and dict
respectively inside the function body. When you define a function signature like this:
def func(*args, **kwds):
# do stuff
it can be called with any number of arguments and keyword arguments. The non-keyword arguments get packed into a list called args
inside the function body and the keyword arguments get packed into a dict called kwds
inside the function body.
func("this", "is a list of", "non-keyowrd", "arguments", keyword="ligma", options=[1,2,3])
now inside the function body, when the function is called, there are two local variables, args
which is a list having value ["this", "is a list of", "non-keyword", "arguments"]
and kwds
which is a dict
having value {"keyword" : "ligma", "options" : [1,2,3]}
This also works in reverse, i.e. from the caller side. for example if you have a function defined as:
def f(a, b, c, d=1, e=10):
# do stuff
you can call it with by unpacking iterables or mappings you have in the calling scope:
iterable = [1, 20, 500]
mapping = {"d" : 100, "e": 3}
f(*iterable, **mapping)
# That call is equivalent to
f(1, 20, 500, d=100, e=3)
I experienced the same issue, same version of Chrome though it's unrelated to the issue. With the developer console I captured an instance of the request that spawned this, and it is an API call served by ad.doubleclick.net

There is something called 'locked reference' in excel which you can use for this, and you use $
symbols to lock a range. For your example, you would use:
=IF(B4<>"",B4/B$1,"")
This locks the 1
in B1
so that when you copy it to rows below, 1
will remain the same.
If you use $B$1
, the range will not change when you copy it down a row or across a column.
Add /usr/local/bin
to your PATH
environment variable, earlier in the list than /usr/bin
.
Generally this is done in your shell's rc file, e.g. for bash, you'd put this in .bashrc
:
export PATH="/usr/local/bin:$PATH"
This will cause your shell to look first for a python
in /usr/local/bin
, before it goes with the one in /usr/bin
.
(Of course, this means you also need to have /usr/local/bin/python
point to python2.7
- if it doesn't already, you'll need to symlink it.)
On a generic note, you can use a combination of ng-if
and ng-style
incorporate conditional changes with change in background image.
<span ng-if="selectedItem==item.id"
ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_active.png)','background-size':'52px 57px','padding-top':'70px','background-repeat':'no-repeat','background-position': 'center'}"></span>
<span ng-if="selectedItem!=item.id"
ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_deactivated.png)','background-size':'52px 57px','padding-top':'70px','background-repeat':'no-repeat','background-position': 'center'}"></span>
Like I use on PHP and JavaScript:
<input type="hidden" id="CatId" value="<?php echo $categoryId; ?>">
Update the JavaScript:
var categoryId = document.getElementById('CatId').value;
Do aman 2 sendfile
. You only need to open the source file on the client and destination file on the server, then call sendfile and the kernel will chop and move the data.
I was having this same issue for both Windows 8 and Windows Server 2012 configurations.
I had installed the latest version of JDK Java 7 and had set my **JAVA_HOME**
system env variable to the jre folder: *C:\Program Files (x86)\Java\jre7*
I also added the bin folder to my **Path**
system env variable: *%JAVA_HOME%\bin
*
But I was still having problems with double clicking the executable jar files. I found another system env variable OPENDS_JAVA_ARGS
that can be used to set the optional properties for javaw.exe. So I added this variable and set it to: -jar
Now I am able to run the executable jar files when double clicking them.
The solution in the accepted answer has a significant drawback - the destructor for the singleton is called after the control leaves the main()
function. There may be problems really, when some dependent objects are allocated inside main
.
I met this problem, when trying to introduce a Singleton in the Qt application. I decided, that all my setup dialogs must be Singletons, and adopted the pattern above. Unfortunately, Qt's main class QApplication
was allocated on stack in the main
function, and Qt forbids creating/destroying dialogs when no application object is available.
That is why I prefer heap-allocated singletons. I provide an explicit init()
and term()
methods for all the singletons and call them inside main
. Thus I have a full control over the order of singletons creation/destruction, and also I guarantee that singletons will be created, no matter whether someone called getInstance()
or not.
When you are storing a DataFrame
object into a csv file using the to_csv
method, you probably wont be needing to store the preceding indices of each row of the DataFrame
object.
You can avoid that by passing a False
boolean value to index
parameter.
Somewhat like:
df.to_csv(file_name, encoding='utf-8', index=False)
So if your DataFrame object is something like:
Color Number
0 red 22
1 blue 10
The csv file will store:
Color,Number
red,22
blue,10
instead of (the case when the default value True
was passed)
,Color,Number
0,red,22
1,blue,10
In the first case you are creating the object on the heap
using new
.
In the second case you are creating the object on the stack
, so it will be disposed of when going out of scope.
In C++
you'll need to delete objects on the heap
explicitly using delete
when you don't Need them anymore.
To call a static method from a class, do
Singleton* singleton = Singleton::get_sample();
in your main-function or wherever.

Today NodeJS supports new async/await
syntax. This is an easy syntax and makes the life much easier
async function process(promises) { // must be an async function
let x = await Promise.all(promises); // now x will be an array
x = x.map( tmp => tmp * 10); // proccessing the data.
}
const promises = [
new Promise(resolve => setTimeout(resolve, 0, 1)),
new Promise(resolve => setTimeout(resolve, 0, 2))
];
process(promises)

SELECT CAST(CAST(year AS varchar) + '/' + CAST(month AS varchar) + '/' + CAST(day as varchar) AS datetime) AS MyDateTime
FROM table
This worked for me. Set the http and https proxy.
This will submit the right form response (i.e. Select value most of the time, and Input value when the Select box is set to "others"). Uses jQuery:
$("select[name="color"]").change(function(){
new_value = $(this).val();
if (new_value == "others") {
$('input[name="color"]').show();
} else {
$('input[name="color"]').val(new_value);
$('input[name="color"]').hide();
}
});
This works
String x = "22/06/2012";
String y = "25/10/2014";
String datestart = x;
String datestop = y;
//DateTimeFormatter format = DateTimeFormat.forPattern("dd/mm/yyyy");
SimpleDateFormat format = new SimpleDateFormat("dd/mm/yyyy");
Date d1 = null;
Date d2 = null;
try {
d1 = format.parse(datestart);
d2 = format.parse(datestop);
DateTime dt1 = new DateTime(d1);
DateTime dt2 = new DateTime(d2);
//Period
period = new Period (dt1,dt2);
//calculate days
int days = Days.daysBetween(dt1, dt2).getDays();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
You can create a function:
function changeInputType(oldObj, oTyp, nValue) {
var newObject = document.createElement('input');
newObject.type = oTyp;
if(oldObj.size) newObject.size = oldObj.size;
if(oldObj.value) newObject.value = nValue;
if(oldObj.name) newObject.name = oldObj.name;
if(oldObj.id) newObject.id = oldObj.id;
if(oldObj.className) newObject.className = oldObj.className;
oldObj.parentNode.replaceChild(newObject,oldObj);
return newObject;
}
And you do a call like:
changeInputType(document.getElementById('DATE_RANGE_VALUE'), 'checkbox', 7);
-L
returns true if the "file" exists and is a symbolic link (the linked file may or may not exist). You want -f
(returns true if file exists and is a regular file) or maybe just -e
(returns true if file exists regardless of type).
According to the GNU manpage, -h
is identical to -L
, but according to the BSD manpage, it should not be used:
-h file
True if file exists and is a symbolic link. This operator is retained for compatibility with previous versions of this program. Do not rely on its existence; use -L instead.
this can be tried out. simple. really does not use nuances of the string class though.

Do NOT loop through all cells!! There is a lot of overhead in communications between worksheets and VBA, for both reading and writing. Looping through all cells will be agonizingly slow. I'm talking hours.
Instead, load an entire sheet at once into a Variant array. In Excel 2003, this takes about 2 seconds (and 250 MB of RAM). Then you can loop through it in no time at all.
In Excel 2007 and later, sheets are about 1000 times larger (1048576 rows × 16384 columns = 17 billion cells, compared to 65536 rows × 256 columns = 17 million in Excel 2003). You will run into an "Out of memory" error if you try to load the whole sheet into a Variant; on my machine I can only load 32 million cells at once. So you have to limit yourself to the range you know has actual data in it, or load the sheet bit by bit, e.g. 30 columns at a time.
Option Explicit
Sub test()
Dim varSheetA As Variant
Dim varSheetB As Variant
Dim strRangeToCheck As String
Dim iRow As Long
Dim iCol As Long
strRangeToCheck = "A1:IV65536"
' If you know the data will only be in a smaller range, reduce the size of the ranges above.
Debug.Print Now
varSheetA = Worksheets("Sheet1").Range(strRangeToCheck)
varSheetB = Worksheets("Sheet2").Range(strRangeToCheck) ' or whatever your other sheet is.
Debug.Print Now
For iRow = LBound(varSheetA, 1) To UBound(varSheetA, 1)
For iCol = LBound(varSheetA, 2) To UBound(varSheetA, 2)
If varSheetA(iRow, iCol) = varSheetB(iRow, iCol) Then
' Cells are identical.
' Do nothing.
Else
' Cells are different.
' Code goes here for whatever it is you want to do.
End If
Next iCol
Next iRow
End Sub
To compare to a sheet in a different workbook, open that workbook and get the sheet as follows:
Set wbkA = Workbooks.Open(filename:="C:\MyBook.xls")
Set varSheetA = wbkA.Worksheets("Sheet1") ' or whatever sheet you need
The advantages of EditorFor
is that your code is not tied to an <input type="text"
. So if you decide to change something to the aspect of how your textboxes are rendered like wrapping them in a div
you could simply write a custom editor template (~/Views/Shared/EditorTemplates/string.cshtml
) and all your textboxes in your application will automatically benefit from this change whereas if you have hardcoded Html.TextBoxFor
you will have to modify it everywhere. You could also use Data Annotations to control the way this is rendered.
According to String class documentation they are equivalent.
Documentation for String(String original)
also says that: Unless an explicit copy of original is needed, use of this constructor is unnecessary since Strings are immutable.
Look for other responses, because it seems that Java documentation is misleading :(
The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName
to be the name of the file you wish to open.
Private Const TargetWBName As String = "myworkbook.xlsx"
'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
WorkbookOpen = False
On Error GoTo WorkBookNotOpen
If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
WorkbookOpen = True
Exit Function
End If
WorkBookNotOpen:
End Function
Private Sub Workbook_Open()
'Check if our target workbook is open
If WorkbookOpen(TargetWBName) = False Then
'set calculation to manual
Application.Calculation = xlCalculationManual
Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
DoEvents
Me.Close False
End If
End Sub
Set the constant 'TargetWBName' to be the name of the workbook that you wish to open.
This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself.
*NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True
after Me.Close
These solutions seem to assume that each item in your drop down lists has a val() value relating to their position in the drop down list.
Things are a little more complicated if this isn't the case.
To read the selected index of a drop down list, you would use this:
$("#dropDownList").prop("selectedIndex");
To set the selected index of a drop down list, you would use this:
$("#dropDownList").prop("selectedIndex", 1);
Note that the prop() feature requires JQuery v1.6 or later.
Let's see how you would use these two functions.
Supposing you had a drop down list of month names.
<select id="listOfMonths">
<option id="JAN">January</option>
<option id="FEB">February</option>
<option id="MAR">March</option>
</select>
You could add a "Previous Month" and "Next Month" button, which looks at the currently selected drop down list item, and changes it to the previous/next month:
<button id="btnPrevMonth" title="Prev" onclick="btnPrevMonth_Click();return false;" />
<button id="btnNextMonth" title="Next" onclick="btnNextMonth_Click();return false;" />
And here's the JavaScript which these buttons would run:
function btnPrevMonth_Click() {
var selectedIndex = $("#listOfMonths").prop("selectedIndex");
if (selectedIndex > 0) {
$("#listOfMonths").prop("selectedIndex", selectedIndex - 1);
}
}
function btnNextMonth_Click() {
// Note: the JQuery "prop" function requires JQuery v1.6 or later
var selectedIndex = $("#listOfMonths").prop("selectedIndex");
var itemsInDropDownList = $("#listOfMonths option").length;
// If we're not already selecting the last item in the drop down list, then increment the SelectedIndex
if (selectedIndex < (itemsInDropDownList - 1)) {
$("#listOfMonths").prop("selectedIndex", selectedIndex + 1);
}
}
My site is also useful for showing how to populate a drop down list with JSON data:
http://mikesknowledgebase.com/pages/Services/WebServices-Page8.htm
I personally find it easier use MySQL event scheduler than cron.
Enable it with
SET GLOBAL event_scheduler = ON;
and create an event like this:
CREATE EVENT name_of_event
ON SCHEDULE EVERY 1 DAY
STARTS '2014-01-18 00:00:00'
DO
DELETE FROM tbl_message WHERE DATEDIFF( NOW( ) , timestamp ) >=7;
and that's it.
Read more about the syntax here and here is more general information about it.
Maybe in your data source add a column which does a sumif over all rows.
Not sure what your data looks like but something like =(sumif([column holding pivot row heads),[current row head value in row], probability column)>.2).
This will give you a True when the pivot table will show >20%.
Then add a filter on your pivot table on this column for TRUE values
It could be some other line as well. PHP is not always that exact.
Probably you are just missing a semicolon on previous line.
How to reproduce this error, put this in a file called a.php
:
<?php
$a = 5
$b = 7; // Error happens here.
print $b;
?>
Run it:
eric@dev ~ $ php a.php
PHP Parse error: syntax error, unexpected T_VARIABLE in
/home/el/code/a.php on line 3
Explanation:
The PHP parser converts your program to a series of tokens. A T_VARIABLE
is a Token of type VARIABLE. When the parser processes tokens, it tries to make sense of them, and throws errors if it receives a variable where none is allowed.
In the simple case above with variable $b
, the parser tried to process this:
$a = 5 $b = 7;
The PHP parser looks at the $b after the 5 and says "that is unexpected".
The best way is to use simple math
>>> a = 8
>>> a**(1./3.)
2.0
EDIT
For Negative numbers
>>> a = -8
>>> -(-a)**(1./3.)
-2.0
Complete Program for all the requirements as specified
x = int(input("Enter an integer: "))
if x>0:
ans = x**(1./3.)
if ans ** 3 != abs(x):
print x, 'is not a perfect cube!'
else:
ans = -((-x)**(1./3.))
if ans ** 3 != -abs(x):
print x, 'is not a perfect cube!'
print 'Cube root of ' + str(x) + ' is ' + str(ans)
Please ensure that both the tables are in InnoDB format. Even if one is in MyISAM format, then, foreign key constraint wont work.
Also, another thing is that, both the fields should be of the same type. If one is INT, then the other should also be INT. If one is VARCHAR, the other should also be VARCHAR, etc.
The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.
That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!

You can use this to get a name of any provided member:
public static class MemberInfoGetting
{
public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
{
MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
return expressionBody.Member.Name;
}
}
To get name of a variable:
string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);
To get name of a parameter:
public class TestClass
{
public void TestMethod(string param1, string param2)
{
string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
}
}
You can use the nameof operator for parameters, variables and properties alike:
string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);
I landed on this question because I needed to attach an Excel file I generate through code and is available as MemoryStream
. I could attach it to the mail message but it was sent as 64Bytes file instead of a ~6KB as it was meant. So, the solution that worked for me was this:
MailMessage mailMessage = new MailMessage();
Attachment attachment = new Attachment(myMemorySteam, new ContentType(MediaTypeNames.Application.Octet));
attachment.ContentDisposition.FileName = "myFile.xlsx";
attachment.ContentDisposition.Size = attachment.Length;
mailMessage.Attachments.Add(attachment);
Setting the value of attachment.ContentDisposition.Size
let me send messages with the correct size of attachment.
EDIT: I would appreciate it if you do not downvote this answer further. This answer is wrong, but I would rather retain it as a historical note. While it is arguable whether the pytz interface is error-prone, it can do things that dateutil.tz cannot do, especially regarding daylight-saving in the past or in the future. I have honestly recorded my experience in an article "Time zones in Python".
If you are on a Unix-like platform, I would suggest you avoid pytz and look just at /usr/share/zoneinfo. dateutil.tz can utilize the information there.
The following piece of code shows the problem pytz can give. I was shocked when I first found it out. (Interestingly enough, the pytz installed by yum on CentOS 7 does not exhibit this problem.)
import pytz
import dateutil.tz
from datetime import datetime
print((datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('Asia/Shanghai'))
- datetime(2017,2,13,14,29,29, tzinfo=pytz.timezone('UTC')))
.total_seconds())
print((datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.gettz('Asia/Shanghai'))
- datetime(2017,2,13,14,29,29, tzinfo=dateutil.tz.tzutc()))
.total_seconds())
-29160.0
-28800.0
I.e. the timezone created by pytz is for the true local time, instead of the standard local time people observe. Shanghai conforms to +0800, not +0806 as suggested by pytz:
pytz.timezone('Asia/Shanghai')
<DstTzInfo 'Asia/Shanghai' LMT+8:06:00 STD>
EDIT: Thanks to Mark Ransom's comment and downvote, now I know I am using pytz the wrong way. In summary, you are not supposed to pass the result of pytz.timezone(…)
to datetime
, but should pass the datetime
to its localize
method.
Despite his argument (and my bad for not reading the pytz documentation more carefully), I am going to keep this answer. I was answering the question in one way (how to enumerate the supported timezones, though not with pytz), because I believed pytz did not provide a correct solution. Though my belief was wrong, this answer is still providing some information, IMHO, which is potentially useful to people interested in this question. Pytz's correct way of doing things is counter-intuitive. Heck, if the tzinfo created by pytz should not be directly used by datetime
, it should be a different type. The pytz interface is simply badly designed. The link provided by Mark shows that many people, not just me, have been misled by the pytz interface.
$("#list [value='2']").text();
leave a space after the id selector.
You can use an anonymous function;
setInterval(function() { funca(10,3); },500);
If you are looking for content from different domain this will do the trick:
$.ajax({
url:'http://www.corsproxy.com/' +
'en.wikipedia.org/wiki/Briarcliff_Manor,_New_York',
type:'GET',
success: function(data){
$('#content').html($(data).find('#firstHeading').html());
}
});
round
does take negative ndigits
parameter!
>>> round(46,-1)

may solve your case.
The answer from @gunn is correct, target="_blank
makes the link open in a new tab.
But this can be a security risk for you page; you can read about it here. There is a simple solution for that: adding rel="noopener noreferrer"
.
<a style={{display: "table-cell"}} href = "someLink" target = "_blank"
rel = "noopener noreferrer">text</a>
Find the following , it will help you to print the complete triangle.
package com.raju.arrays;
public class CompleteTriange {
public static void main(String[] args) {
int nuberOfRows = 10;
for(int row = 0; row<nuberOfRows;row++){
for(int leftspace =0;leftspace<(nuberOfRows-row);leftspace++){
System.out.print(" ");
}
for(int star = 0;star<2*row+1;star++){
System.out.print("*");
}
for(int rightSpace =0;rightSpace<(nuberOfRows-row);rightSpace++){
System.out.print(" ");
}
System.out.println("");
}
}
}

or try this:
change_column :table_name, :column_name, :integer, using: 'column_name::integer'

This gets a view controller from the storyboard and presents it.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let secondViewController = storyboard.instantiateViewController(withIdentifier: "secondViewControllerId") as! SecondViewController
self.present(secondViewController, animated: true, completion: nil)
Change the storyboard name, view controller name, and view controller id as appropriate.
The easier way is to just use pprint
, which is in base Python
import pprint
item = MyDjangoModel.objects.get(name = 'foo')
pprint.pprint(item.__dict__, indent = 4)
This gives output that looks similar to json.dumps(..., indent = 4)
but it correctly handles the weird data types that might be embedded in your model instance, such as ModelState
and UUID
, etc.
Tested on Python 3.7
Another good option for handling this kind of option is the pprint
module, which (among other things) pretty prints long lists with one element per line:
>>> import sys
>>> import pprint
>>> pprint.pprint(sys.path)

In some scenarios the intention is to get all DISTINCT LISTAGG keys and the overflow is caused by the fact that LISTAGG concatenates ALL keys.
Here is a small example
create table tab as
select
trunc(rownum/10) x,
'GRP'||to_char(mod(rownum,4)) y,
mod(rownum,10) z
from dual connect by level < 100;
select
x,
LISTAGG(y, '; ') WITHIN GROUP (ORDER BY y) y_lst
from tab
group by x;
X Y_LST
---------- ------------------------------------------------------------------
0 GRP0; GRP0; GRP1; GRP1; GRP1; GRP2; GRP2; GRP3; GRP3
1 GRP0; GRP0; GRP1; GRP1; GRP2; GRP2; GRP2; GRP3; GRP3; GRP3
2 GRP0; GRP0; GRP0; GRP1; GRP1; GRP1; GRP2; GRP2; GRP3; GRP3
3 GRP0; GRP0; GRP1; GRP1; GRP2; GRP2; GRP2; GRP3; GRP3; GRP3
4 GRP0; GRP0; GRP0; GRP1; GRP1; GRP1; GRP2; GRP2; GRP3; GRP3
5 GRP0; GRP0; GRP1; GRP1; GRP2; GRP2; GRP2; GRP3; GRP3; GRP3
6 GRP0; GRP0; GRP0; GRP1; GRP1; GRP1; GRP2; GRP2; GRP3; GRP3
7 GRP0; GRP0; GRP1; GRP1; GRP2; GRP2; GRP2; GRP3; GRP3; GRP3
8 GRP0; GRP0; GRP0; GRP1; GRP1; GRP1; GRP2; GRP2; GRP3; GRP3
9 GRP0; GRP0; GRP1; GRP1; GRP2; GRP2; GRP2; GRP3; GRP3; GRP3
If the groups are large, the repeated keys reach quickly the allowed maximal length and you get the ORA-01489: result of string concatenation is too long
.
Unfortunately there is no support for LISTAGG( DISTINCT y, '; ')
but as a workaround the fact can be used that LISTAGG ignores NULLs. Using the ROW_NUMBER we will consider only the first key.
with rn as (
select x,y,z,
row_number() over (partition by x,y order by y) rn
from tab
)
select
x,
LISTAGG( case when rn = 1 then y end, '; ') WITHIN GROUP (ORDER BY y) y_lst,
sum(z) z
from rn
group by x
order by x;
X Y_LST Z
---------- ---------------------------------- ----------
0 GRP0; GRP1; GRP2; GRP3 45
1 GRP0; GRP1; GRP2; GRP3 45
2 GRP0; GRP1; GRP2; GRP3 45
3 GRP0; GRP1; GRP2; GRP3 45
4 GRP0; GRP1; GRP2; GRP3 45
5 GRP0; GRP1; GRP2; GRP3 45
6 GRP0; GRP1; GRP2; GRP3 45
7 GRP0; GRP1; GRP2; GRP3 45
8 GRP0; GRP1; GRP2; GRP3 45
9 GRP0; GRP1; GRP2; GRP3 45
Of course the same result may be reached using GROUP BY x,y
in the subquery. The advantage of ROW_NUMBER
is that all other aggregate functions may be used as illustrated with SUM(z)
.
The HTTP POST payload is just a flat bunch of bytes. Django (like most frameworks) decodes it into a dictionary from either URL encoded parameters, or MIME-multipart encoding. If you just dump the JSON data in the POST content, Django won't decode it. Either do the JSON decoding from the full POST content (not the dictionary); or put the JSON data into a MIME-multipart wrapper.
In short, show the JavaScript code. The problem seems to be there.
Since you're using requests
, you should use the response's json
method.
import requests
response = requests.get(...)
data = response.json()
Sounds like your initial migration was faked because the table already existed (probably with an outdated schema):
https://docs.djangoproject.com/en/1.7/topics/migrations/#adding-migrations-to-apps
"This will make a new initial migration for your app. Now, when you run migrate, Django will detect that you have an initial migration and that the tables it wants to create already exist, and will mark the migration as already applied."
Otherwise you would get an no-such-table error :)
[edit] did you clean up the applied-migrations table? That's also a common cause for non-applied migrations.
This worked for me:
string connection = System.Configuration.ConfigurationManager.ConnectionStrings["Test"].ConnectionString;
Outputs:
Data Source=.;Initial Catalog=OmidPayamak;IntegratedSecurity=True"
Why do you use new Array();
for hash? You need to use new Object()
instead.
And i think you will get what you want.
The regular expression:
^[^_]*_(.*)$
Then get the part between parenthesis. In perl:
my var = "3.04_somename.jpg";
$var =~ m/^[^_]*_(.*)$/;
my fileName = $1;
In Java:
String var = "3.04_somename.jpg";
String fileName = "";
Pattern pattern = Pattern.compile("^[^_]*_(.*)$");
Matcher matcher = pattern.matcher(var);
if (matcher.matches()) {
fileName = matcher.group(1);
}
...
See ?merge
:
the name "row.names" or the number 0 specifies the row names.
Example:
R> de <- merge(d, e, by=0, all=TRUE) # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0 # replace NA values
R> de

var socket = new WebSocket(uri);
socket.onclose = function (e){
console.log(connection closed);
};
window.addEventListener("unload", function () {

Close browser doesn't trigger websocket close event. You must call socket.close() manually.
Dead simple. No plugins needed.
var $container = $('div'),
$scrollTo = $('#row_8');
$container.scrollTop(
$scrollTo.offset().top - $container.offset().top + $container.scrollTop()
);
// Or you can animate the scrolling:
$container.animate({
scrollTop: $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
});?
Here is a working example.
In pom.xml manage or remove ../src/main/resources
Actually asXML() converts the string into xml as it name says:
<id>5</id>
This will display normally on a web page but it will cause problems when you matching values with something else.
You may use strip_tags function to get real value of the field like:
$newString = strip_tags($xml->asXML());
PS: if you are working with integers or floating numbers, you need to convert it into integer with intval() or floatval().
$newNumber = intval(strip_tags($xml->asXML()));
Parameters starting with -
or --
are usually considered optional. All other parameters are positional parameters and as such required by design (like positional function arguments). It is possible to require optional arguments, but this is a bit against their design. Since they are still part of the non-positional arguments, they will still be listed under the confusing header “optional arguments” even if they are required. The missing square brackets in the usage part however show that they are indeed required.
See also the documentation:
In general, the argparse module assumes that flags like -f and --bar indicate optional arguments, which can always be omitted at the command line.
Note: Required options are generally considered bad form because users expect options to be optional, and thus they should be avoided when possible.
That being said, the headers “positional arguments” and “optional arguments” in the help are generated by two argument groups in which the arguments are automatically separated into. Now, you could “hack into it” and change the name of the optional ones, but a far more elegant solution would be to create another group for “required named arguments” (or whatever you want to call them):
parser = argparse.ArgumentParser(description='Foo')
parser.add_argument('-o', '--output', help='Output file name', default='stdout')
requiredNamed = parser.add_argument_group('required named arguments')
requiredNamed.add_argument('-i', '--input', help='Input file name', required=True)
parser.parse_args(['-h'])
usage: [-h] [-o OUTPUT] -i INPUT
Foo
optional arguments:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT
Output file name
required named arguments:
-i INPUT, --input INPUT
Input file name
I have found a solution of git bash command when you try to build war using git mvn clean install for “java.lang.OutOfMemoryError: PermGen space” in Maven build error come
use below command first
$ export MAVEN_OPTS="-Xmx512m -Xss32m"
then use your mvn command to clean install /build war file
$ mvn clean install
NOTE: you don't need -XX:MaxPermSize argument in MAVEN_OPTS when your are using jdk1.8
Java HotSpot(TM) Client VM warning: ignoring option MaxPermSize=XXXm; support was removed in 8.0

foreach (string file in Directory.EnumerateFiles(folderPath, "*.xml"))
{
string contents = File.ReadAllText(file);
}
Note the above uses a .NET 4.0 feature; in previous versions replace EnumerateFiles
with GetFiles
). Also, replace File.ReadAllText
with your preferred way of reading xml files - perhaps XDocument
, XmlDocument
or an XmlReader
.
You can create a DAO method to do this.
@Dao
interface MyDao {
@Query("DELETE FROM myTableName")
public void nukeTable();
}
To answer your question and on all variable substitutions
echo "$\{var}"
echo "Substitute the value of var."
echo "$\{var:-word}"
echo "If var is null or unset, word is substituted for var. The value of var does not change."
echo "$\{var:=word}"
echo "If var is null or unset, var is set to the value of word."
echo "$\{var:?message}"
echo "If var is null or unset, message is printed to standard error. This checks that variables are set correctly."
echo "$\{var:+word}"
echo "If var is set, word is substituted for var. The value of var does not change."
Or a simple sort! Keeping it real :)
array.sort((a,b)=>a.y<b.y)[0].y
try kill -9 {processID}
To find the process ID you can use ps -ef | grep gedit

My problem was that excel column was showing me "=concatenate(A1,B1)"
instead of
it 's value after concatenation.
I added a space after "," like this =concatenate(A1, B1)
and it worked.
This is just an example that solved my problem.
Try and let me know if it works for you as well.
Sometimes it works without space as well, but at other times it doesn't.
If your file contains n lines, then your script has to read the file n times; so if you double the length of the file, you quadruple the amount of work your script does — and almost all of that work is simply thrown away, since all you want to do is loop over the lines in order.
Instead, the best way to loop over the lines of a file is to use a while
loop, with the condition-command being the read
builtin:
while IFS= read -r line ; do
# $line is a single line of the file, as a single string
: ... commands that use $line ...
done < input_file.txt
In your case, since you want to split the line into an array, and the read
builtin actually has special support for populating an array variable, which is what you want, you can write:
while read -r -a line ; do
echo ""${line[1]}" "${line[3]}"" >> out.txt
done < /path/of/my/text
or better yet:
while read -r -a line ; do
echo "${line[1]} ${line[3]}"
done < /path/of/my/text > out.txt
However, for what you're doing you can just use the cut
utility:
cut -d' ' -f2,4 < /path/of/my/text > out.txt
(or awk
, as Tom van der Woerdt suggests, or perl
, or even sed
).
Here is my solution:
function getWeekDates(){
var day_milliseconds = 24*60*60*1000;
var dates = [];
var current_date = new Date();
var monday = new Date(current_date.getTime()-(current_date.getDay()-1)*day_milliseconds);
var sunday = new Date(monday.getTime()+6*day_milliseconds);
dates.push(monday);
for(var i = 1; i < 6; i++){
dates.push(new Date(monday.getTime()+i*day_milliseconds));
}
dates.push(sunday);
return dates;
}
Now you can pick date by returned array index.
I know this is an old thread but I tried the suggested answers and unfortunately simply replacing line breaks with <br />
didn't do what I needed it to. It simply rendered them literally as text.
One solution would have been to disable autoescape like this: {% autoescape false %}{{ mystring }}{% endautoescape %}
and this works fine but this is no good if you have user-provided content. So this was also not a solution for me.
So this is what I used:
In Python:
newvar = mystring.split('\n')
And then, passing newvar
into my Jinja template:
{% for line in newvar %}
<br />{{ line }}
{% endfor %}
Here are two WORKAROUNDS to the problem of triggering downloads from the client only. In later browsers you should look at "blob"
1. Drag and drop the table
Did you know you can simply DRAG your table into excel?
Here is how to select the table to either cut and past or drag
Select a complete table with Javascript (to be copied to clipboard)
2. create a popup page from your div
Although it will not produce a save dialog, if the resulting popup is saved with extension .csv, it will be treated correctly by Excel.
The string could be
w.document.write("row1.1\trow1.2\trow1.3\nrow2.1\trow2.2\trow2.3");
e.g. tab-delimited with a linefeed for the lines.
There are plugins that will create the string for you - such as http://plugins.jquery.com/project/table2csv
var w = window.open('','csvWindow'); // popup, may be blocked though
// the following line does not actually do anything interesting with the
// parameter given in current browsers, but really should have.
// Maybe in some browser it will. It does not hurt anyway to give the mime type
w.document.open("text/csv");
w.document.write(csvstring); // the csv string from for example a jquery plugin
w.document.close();
DISCLAIMER: These are workarounds, and does not fully answer the question which currently has the answer for most browser: not possible on the client only
Activation by system properties can be done as follows
<activation>
<property>
<name>foo</name>
<value>bar</value>
</property>
</activation>
And run the mvn build with -D to set system property
mvn clean install -Dfoo=bar
This method also helps select profiles in transitive dependency of project artifacts.
If you install a JDK and choose to install sources too, the src.zip contains the source of ALL the public Java classes. Most of these have pretty good javadoc.
you can make use of the following code:
from __future__ import division, unicode_literals
import codecs
from bs4 import BeautifulSoup
f=codecs.open("test.html", 'r', 'utf-8')
document= BeautifulSoup(f.read()).get_text()
print document
If you want to delete all the blank lines in between and get all the words as a string (also avoid special characters, numbers) then also include:
import nltk
from nltk.tokenize import word_tokenize
docwords=word_tokenize(document)
for line in docwords:
line = (line.rstrip())
if line:
if re.match("^[A-Za-z]*$",line):
if (line not in stop and len(line)>1):
st=st+" "+line
print st
*define st
as a string
initially, like st=""

FROM table_name a,(SELECT userid,Max(date1)AS mm FROM table_name GROUP BY userid) b
WHERE a.userid=b.userid AND a.DATE1=b.mm;

You are testing if the values of the variables error
and Already
are present in RepoOutput[RepoName.index(repo)]
. If these variables don't exist then an undefined object is used.
Both of your if
and elif
tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].
I think you wanted to test if certain strings are in the value instead:
{% if "error" in RepoOutput[RepoName.index(repo)] %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
<td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>
Other corrections I made:
{% elif ... %}
instead of {$ elif ... %}
.</tr>
tag out of the if
conditional structure, it needs to be there always.id
attributeNote that most likely you want to use a class
attribute instead here, not an id
, the latter must have a value that must be unique across your HTML document.
Personally, I'd set the class value here and reduce the duplication a little:
{% if "Already" in RepoOutput[RepoName.index(repo)] %}
{% set row_class = "good" %}
{% else %}
{% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>
I would simplify the most voted answer to:
BS="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
def to_base(n, b):
return "0" if not n else to_base(n//b, b).lstrip("0") + BS[n%b]
With the same advice for RuntimeError: maximum recursion depth exceeded in cmp
on very large integers and negative numbers. (You could usesys.setrecursionlimit(new_limit)
)
To avoid recursion problems:
BS="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
def to_base(s, b):
res = ""
while s:
res+=BS[s%b]
s//= b
return res[::-1] or "0"
Don't store the whole structure in memory while waiting to get to the end.
Write intermediate results to a temporary table in the database instead of hashmaps - functionally, a database table is the equivalent of a hashmap, i.e. both support keyed access to data, but the table is not memory bound, so use an indexed table here rather than the hashmaps.
If done correctly, your algorithm should not even notice the change - correctly here means to use a class to represent the table, even giving it a put(key, value) and a get(key) method just like a hashmap.
When the intermediate table is complete, generate the required sql statement(s) from it instead of from memory.
One can use base python for this. The code needs a function to flatten lists of lists:
def flatten(B): # function needed for code below;
A = []
for i in B:
if type(i) == list: A.extend(i)
else: A.append(i)
return A
Then one can run:
L = [[1,2,3],[4,5,6],[7,8,9,10]]

Just put DROP TABLE IF EXISTS `tablename`;
before your CREATE TABLE
statement.
That statement drops the table if it exists but will not throw an error if it does not.
Lot of concepts here which will be useful:
List<Object> list = new ArrayList<Object>(Arrays.asList(new String[]{"Java","is","cool"}));
String[] a = new String[list.size()];
list.toArray(a);
Tip to print array of Strings:
System.out.println(Arrays.toString(a));
Timezones and stuff aside, a very simple alternative to new Date(startDateLong)
could be LocalDate.ofEpochDay(startDateLong / 86400000L)
Late to the party. Building off the other solutions. I needed a way to pass the target DIV as a variable. Here is what I did.
HTML for Popover source (added a data attribute data-pop that will hold value for destination DIV id/or class):
<div data-html="true" data-toggle="popover" data-pop="popper-content" class="popper">
HTML for Popover content (I am using bootstrap hide class):
<div id="popper-content" class="hide">Content goes here</div>
Script:
$('.popper').popover({
placement: popover_placement,
container: 'div.page-content',
html: true,
trigger: 'hover',
content: function () {
var pop_dest = $(this).attr("data-pop");
//console.log(plant);
return $("#"+pop_dest).html();
}});
The easiest is to create a batch file (.bat) and run that as administrator.
Right click and 'Run as administrator'
This should work:
SELECT * FROM Accounts WHERE Username LIKE '%$query%'
Hey, I have used the same software on an AMD 3Ghz chip, dual core. had 2gbs of ram at the time, and i noticed the emulator ran at an alright speed, but took a ridiculous amount of time to load. I have not done enough development on Android to tell you if this is a common, or even still existing problem, but it is certainly something I remember from my experience.
If you want to revert the file to its state in master
:
git checkout origin/master [filename]
I think that besides some syntax limitations; the naming conventions reasoning are very much language independent. I mean, the arguments in favor of c_style_functions and JavaLikeCamelCase could equally well be used the opposite way, it's just that language users tend to follow the language authors.
having said that, i think most libraries tend to roughly follow a simplification of Java's CamelCase. I find Douglas Crockford advices tasteful enough for me.
You can just do that too, it seems to work well too.
sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"
You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.
One of the cleanest and most flexible way would be using Template Literals.
An advantage of using this is, if you want to display the content of string variable in the text body, it is cleaner and straight forward.
(Please note the usage of backtick characters)
const customMessage = 'This is a test message';
<Text>
{`
Hi~
${customMessage}
`}
</Text>
Would result in

This is a test message
If you only want to read the first 999,999 (non-header) rows:
read_csv(..., nrows=999999)
If you only want to read rows 1,000,000 ... 1,999,999
read_csv(..., skiprows=1000000, nrows=999999)
nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*
skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file
and for large files, you'll probably also want to use chunksize:
chunksize : int, default None Return TextFileReader object for iteration
The following function should do what you want exactly:
hush=function(code){
sink("NUL") # use /dev/null in UNIX
tmp = code
sink()
return(tmp)
}
For example with the function here:
foo=function(){
print("BAR!")
return(42)
}
running
x = hush(foo())
Will assign 42 to x but will not print "BAR!" to STDOUT
Note than in a UNIX OS you will need to replace "NUL" with "/dev/null"
jus do this import { shallow, mount } from "enzyme";

You may directly right-click on the table name - that also shows the "Import Data.." option.Then you can follow few simple steps & succeed.
Do anyone know how to import a new table with data from excel?
if use Inline CSS you use
<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>
Otherwise you can use class properties which related with a separate css file (styling your website) as like In CSS File
.imgSize {height:100px;width:100px;}
In HTML File
<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>
I believe this won't work because you are using a console application and there is no Event Loop running. An Event Loop / Message Pump used for event handling is setup automatically when a Winforms application is created, but not for a console app.
Each tablespace has one or more datafiles that it uses to store data.
The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.
To find out if the actual limit is 32gb, run the following:
select value from v$parameter where name = 'db_block_size';
Compare the result you get with the first column below, and that will indicate what your max datafile size is.
I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).
Block Sz Max Datafile Sz (Gb) Max DB Sz (Tb)
-------- -------------------- --------------
2,048 8,192 524,264
4,096 16,384 1,048,528
8,192 32,768 2,097,056
16,384 65,536 4,194,112
32,768 131,072 8,388,224
You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):
select bytes/1024/1024 as mb_size,
maxbytes/1024/1024 as maxsize_set,
x.*
from dba_data_files x
MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).
If your datafile has a low max size or autoextend is not on you could simply run:
alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;
However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:
alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

It is best to make the condition (monitored by your condition variable) the inverse condition of a while-loop:
while(!some_condition)
. Inside this loop, you go to sleep if your condition fails, triggering the body of the loop.
This way, if your thread is awoken--possibly spuriously--your loop will still check the condition before proceeding. Think of the condition as the state of interest, and think of the condition variable as more of a signal from the system that this state might be ready. The loop will do the heavy lifting of actually confirming that it's true, and going to sleep if it's not.
I just wrote a template for an async queue, hope this helps. Here, q.empty()
is the inverse condition of what we want: for the queue to have something in it. So it serves as the check for the while loop.
#ifndef SAFE_QUEUE
#define SAFE_QUEUE
#include <queue>
#include <mutex>
#include <condition_variable>
// A threadsafe-queue.
template <class T>
class SafeQueue
{
public:
SafeQueue(void)
: q()
, m()
, c()
{}
~SafeQueue(void)
{}
// Add an element to the queue.
void enqueue(T t)
{
std::lock_guard<std::mutex> lock(m);
q.push(t);
c.notify_one();
}
// Get the "front"-element.
// If the queue is empty, wait till a element is avaiable.
T dequeue(void)
{
std::unique_lock<std::mutex> lock(m);
while(q.empty())
{
// release lock as long as the wait and reaquire it afterwards.
c.wait(lock);
}
T val = q.front();
q.pop();
return val;
}
private:
std::queue<T> q;
mutable std::mutex m;
std::condition_variable c;
};
#endif

Try Access DataTable easiest way which can help you for getting perfect idea for accessing DataTable, DataSet using Linq...
Consider following example, suppose we have DataTable like below.
DataTable ObjDt = new DataTable("List");
ObjDt.Columns.Add("WorkName", typeof(string));
ObjDt.Columns.Add("Price", typeof(decimal));
ObjDt.Columns.Add("Area", typeof(string));
ObjDt.Columns.Add("Quantity",typeof(int));
ObjDt.Columns.Add("Breath",typeof(decimal));
ObjDt.Columns.Add("Length",typeof(decimal));
Here above is the code for DatTable, here we assume that there are some data are available in this DataTable, and we have to bind Grid view of particular by processing some data as shown below.
Area | Quantity | Breath | Length | Price = Quantity * breath *Length
Than we have to fire following query which will give us exact result as we want.
var data = ObjDt.AsEnumerable().Select
(r => new
{
Area = r.Field<string>("Area"),
Que = r.Field<int>("Quantity"),
Breath = r.Field<decimal>("Breath"),
Length = r.Field<decimal>("Length"),
totLen = r.Field<int>("Quantity") * (r.Field<decimal>("Breath") * r.Field<decimal>("Length"))
}).ToList();
We just have to assign this data variable as Data Source.
By using this simple Linq query we can get all our accepts, and also we can perform all other LINQ queries with this…
They are synonyms, no difference at all.Decimal and Numeric data types are numeric data types with fixed precision and scale.
-- Initialize a variable, give it a data type and an initial value
declare @myvar as decimal(18,8) or numeric(18,8)----- 9 bytes needed
-- Increse that the vaue by 1
set @myvar = 123456.7
--Retrieve that value
select @myvar as myVariable
This query should work for you:
SELECT *
FROM table
WHERE MONTH(columnName) = MONTH(CURRENT_DATE())
AND YEAR(columnName) = YEAR(CURRENT_DATE())
If you are using SQL Server 2016 or newer, you can also select it as JSON result and display it in JSON Visualizer, it's much easier to read it than in XML and allows you to filter results.
DECLARE @v nvarchar(max) = (SELECT * FROM Suppliers FOR JSON AUTO)
war - web archive. It is used to deploy web applications according to the servlet standard. It is a jar file containing a special directory called WEB-INF and several files and directories inside it (web.xml, lib, classes) as well as all the HTML, JSP, images, CSS, JavaScript and other resources of the web application
ear - enterprise archive. It is used to deploy enterprise application containing EJBs, web applications, and 3rd party libraries. It is also a jar file, it has a special directory called APP-INF that contains the application.xml file, and it contains jar and war files.

In Convert.ToString()
, the Convert handles either a NULL

it does not handles a NULL
value and a NULL

.
You can link to any file or directory with the help of a simple PowerShell script.
Open Windows PowerShell ISE. In the script pane write:
New-Alias ${shortcutName} ${fullFileLocation}
Then head to the command-line pane. Find your PowerShell user profile address with echo $profile
. Save the script in this address.
The script in PowerShell's profile address will run each time you open powershell. The shortcut should work with every new PowerShell window.
It requires another line in our script.
function ${nameOfFunction} {set-location ${directory_location}}
New-Alias ${shortcut} ${nameOfFunction}
The rest is exactly the same.
By default PowerShell scripts are blocked. To enable them, open settings -> Update & Security -> For developers. Select Developer Mode (might require restart). .
Scroll down to the PowerShell section, tick the "Change execution policy ..." option, and apply.
You are reducing the length of your list l
as you iterate over it, so as you approach the end of your indices in the range statement, some of those indices are no longer valid.
It looks like what you want to do is:
l = [x for x in l if x != 0]
which will return a copy of l
without any of the elements that were zero (that operation is called a list comprehension, by the way). You could even shorten that last part to just if x
, since non-zero numbers evaluate to True
.
There is no such thing as a loop termination condition of i < len(l)
, in the way you've written the code, because len(l)
is precalculated before the loop, not re-evaluated on each iteration. You could write it in such a way, however:
i = 0
while i < len(l):
if l[i] == 0:
l.pop(i)
else:
i += 1
I use a method like that to check duplicated entrys in a string:
public static IEnumerable<string> CheckForDuplicated(IEnumerable<string> listString)
{
List<string> duplicateKeys = new List<string>();
List<string> notDuplicateKeys = new List<string>();
foreach (var text in listString)
{
if (notDuplicateKeys.Contains(text))
{
duplicateKeys.Add(text);
}
else
{
notDuplicateKeys.Add(text);
}
}
return duplicateKeys;
}
Maybe it's not the most shorted or elegant way, but I think that is very readable.
1) Normally, you would want to return a Task
. The main exception should be when you need to have a void
return type (for events). If there's no reason to disallow having the caller await
your task, why disallow it?
2) async
methods that return void
are special in another aspect: they represent top-level async operations, and have additional rules that come into play when your task returns an exception. The easiest way is to show the difference is with an example:
static async void f()
{
await h();
}
static async Task g()
{
await h();
}
static async Task h()
{
throw new NotImplementedException();
}
private void button1_Click(object sender, EventArgs e)
{
f();
}
private void button2_Click(object sender, EventArgs e)
{
g();
}
private void button3_Click(object sender, EventArgs e)
{
GC.Collect();
}
f
's exception is always "observed". An exception that leaves a top-level asynchronous method is simply treated like any other unhandled exception. g
's exception is never observed. When the garbage collector comes to clean up the task, it sees that the task resulted in an exception, and nobody handled the exception. When that happens, the TaskScheduler.UnobservedTaskException
handler runs. You should never let this happen. To use your example,
public static async void AsyncMethod2(int num)
{
await Task.Factory.StartNew(() => Thread.Sleep(num));
}
Yes, use async
and await
here, they make sure your method still works correctly if an exception is thrown.

For swift 4, xcode 9
myButton.contentHorizontalAlignment = .center
This is the simplest solution:
SELECT quote FROM quotes ORDER BY RAND()
Although it is not the most efficient. This one is a better solution.
I implemented a function that might meet your needs. It is based on string_view's constexpr function find_last_of (since c++17) which can be calculated at compile time
constexpr const char* base_filename(const char* p) {
const size_t i = std::string_view(p).find_last_of('/');
return std::string_view::npos == i ? p : p + i + 1 ;
}
//in the file you used this function
base_filename(__FILE__);
By far the simplest way that I've found:
@Override
public String toString() {
return this.label;
}
Now you can stick any object in your spinner, and it will display the specified label.
MySQL only listens to localhost, if we want to enable the remote access to it, then we need to made some changes in my.cnf file:
sudo nano /etc/mysql/my.cnf
We need to comment out the bind-address and skip-external-locking lines:
#bind-address = 127.0.0.1
# skip-external-locking
After making these changes, we need to restart the mysql service:
sudo service mysql restart
You should use this:
>mysql -u user -h 192.168.1.2 -P 3306 -ppassword
or this:
>mysql -u user -h 192.168.1.2 -ppassword
...because 3306 is a default port number.
The solution by PeterVR has the disadvantage that the additional color displays on top of the entire HTML block - meaning that it also shows up on top of div content, not just on top of the background image. This is fine if your div is empty, but if it is not using a linear gradient might be a better solution:
<div class="the-div">Red text</div>
<style type="text/css">
.the-div
{
background-image: url("the-image.png");
color: #f00;
margin: 10px;
width: 200px;
height: 80px;
}
.the-div:hover
{
background-image: linear-gradient(to bottom, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
background-image: -moz-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
background-image: -o-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
background-image: -ms-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
background-image: -webkit-gradient(linear, left top, left bottom, from(rgba(0, 0, 0, 0.1)), to(rgba(0, 0, 0, 0.1))), url("the-image.png");
background-image: -webkit-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
}
</style>
See fiddle. Too bad that gradient specifications are currently a mess. See compatibility table, the code above should work in any browser with a noteworthy market share - with the exception of MSIE 9.0 and older.
Edit (March 2017): The state of the web got far less messy by now. So the linear-gradient
(supported by Firefox and Internet Explorer) and -webkit-linear-gradient
(supported by Chrome, Opera and Safari) lines are sufficient, additional prefixed versions are no longer necessary.
Both contain the same functionality but the .min.js equivalent has been optimized in size. You can open both files and take a look at them. In the .min.js file you'll notice that all variables names have been reduced to short names and that most whitespace & comments have been taken out.
You can try this script, that converts all of your databases and tables to utf8.
File.exist?("directory")
Dir[]
returns an array, so it will never be nil
. If you want to do it your way, you could do
Dir["directory"].empty?
which will return true
if it wasn't found.
The answer was to install the plugin individually. I installed all the three plugins shown in the screenshot together. And it created the issue. I had to install each plugin individually and then it worked fine. I am able to format the JSON string.
Do we really need a Boost library for seemingly such a simple task?
To replace all occurences of a substring use this function:
std::string ReplaceString(std::string subject, const std::string& search,
const std::string& replace) {
size_t pos = 0;
while ((pos = subject.find(search, pos)) != std::string::npos) {
subject.replace(pos, search.length(), replace);
pos += replace.length();
}
return subject;
}
If you need performance, here is an optimized function that modifies the input string, it does not create a copy of the string:
void ReplaceStringInPlace(std::string& subject, const std::string& search,
const std::string& replace) {
size_t pos = 0;
while ((pos = subject.find(search, pos)) != std::string::npos) {
subject.replace(pos, search.length(), replace);
pos += replace.length();
}
}
Tests:
std::string input = "abc abc def";
std::cout << "Input string: " << input << std::endl;
std::cout << "ReplaceString() return value: "
<< ReplaceString(input, "bc", "!!") << std::endl;
std::cout << "ReplaceString() input string not modified: "
<< input << std::endl;
ReplaceStringInPlace(input, "bc", "??");
std::cout << "ReplaceStringInPlace() input string modified: "
<< input << std::endl;
Output:
Input string: abc abc def
ReplaceString() return value: a!! a!! def
ReplaceString() input string not modified: abc abc def
ReplaceStringInPlace() input string modified: a?? a?? def
I have had the same error. When i check the code then i found that declare "GET" request in my angular (font-end) side and declare "POST" request in the ASP.net (back-end) side. Set POST/GET any one in both side. Then solved the error.
I like your idea of polling the HTML until it's stable. I may add that to my own solution. The following approach is in C# and requires jQuery.
I'm the developer for a SuccessFactors (SaaS) test project where we have no influence at all over the developers or the characteristics of the DOM behind the web page. The SaaS product can potentially change its underlying DOM design 4 times a year, so the hunt is permanently on for robust, performant ways to test with Selenium (including NOT testing with Selenium where possi ble!)
Here's what I use for "page ready". It works in all my own tests currently. The same approach also worked for a big in-house Java web app a couple of years ago, and had been robust for over a year at the time I left the project.
Driver
is the WebDriver instance that communicates with the browserDefaultPageLoadTimeout
is a timeout value in ticks (100ns per tick)public IWebDriver Driver { get; private set; }
// ...
const int GlobalPageLoadTimeOutSecs = 10;
static readonly TimeSpan DefaultPageLoadTimeout =
new TimeSpan((long) (10_000_000 * GlobalPageLoadTimeOutSecs));
Driver = new FirefoxDriver();
In what follows, note the order of waits in method PageReady
(Selenium document ready, Ajax, animations), which makes sense if you think about it:
Something like your DOM comparison approach could be used between 1 and 2 to add another layer of robustness.
public void PageReady()
{
DocumentReady();
AjaxReady();
AnimationsReady();
}
private void DocumentReady()
{
WaitForJavascript(script: "return document.readyState", result: "complete");
}
private void WaitForJavascript(string script, string result)
{
new WebDriverWait(Driver, DefaultPageLoadTimeout).Until(
d => ((IJavaScriptExecutor) d).ExecuteScript(script).Equals(result));
}
private void AjaxReady()
{
WaitForJavascript(script: "return jQuery.active.toString()", result: "0");
}
private void AnimationsReady()
{
WaitForJavascript(script: "return $(\"animated\").length.toString()", result: "0");
}
moment().toISOString(); // or format() - see below
http://momentjs.com/docs/#/displaying/as-iso-string/
Update
Based on the answer: by @sennet and the comment by @dvlsg (see Fiddle) it should be noted that there is a difference between format
and toISOString
. Both are correct but the underlying process differs. toISOString
converts to a Date object, sets to UTC then uses the native Date prototype function to output ISO8601 in UTC with milliseconds (YYYY-MM-DD[T]HH:mm:ss.SSS[Z]
). On the other hand, format
uses the default format (YYYY-MM-DDTHH:mm:ssZ

I've opened an issue as I think it can lead to unexpected results.
ListView
is the ancestor to RecyclerView
. There were many things that ListView
either didn't do, or didn't do well. If you were to gather the shortcomings of the ListView
and solved the problem by abstracting the problems into different domains you'd end up with something like the recycler view. Here are the main problem points with ListViews:
Didn't enforce View
Reuse for same item types (look at one of the adapters that are used in a ListView
, if you study the getView method you will see that nothing prevents a programmer from creating a new view for every row even if one is passed in via the convertView
variable)
Didn't prevent costly findViewById
uses(Even if you were recycling views as noted above it was possible for devs to be calling findViewById
to update the displayed contents of child views. The main purpose of the ViewHolder
pattern in ListViews
was to cache the findViewById
calls. However this was only available if you knew about it as it wasn't part of the platform at all)
Only supported Vertical Scrolling with Row displayed Views (Recycler view doesn't care about where views are placed and how they are moved, it's abstracted into a LayoutManager
. A Recycler can therefore support the traditional ListView
as shown above, as well as things like the GridView
, but it isn't limited to that, it can do more, but you have to do the programming foot work to make it happen).
Animations to added/removed was not a use case that was considered. It was completely up to you to figure out how go about this (compare the RecyclerView. Adapter classes notify* method offerings v. ListViews to get an idea).
In short RecyclerView
is a more flexible take on the ListView
, albeit more coding may need to be done on your part.
Use CASE
:
SELECT
TABEL1.Id,
CASE WHEN EXISTS (SELECT Id FROM TABLE2 WHERE TABLE2.ID = TABLE1.ID)
THEN 'TRUE'
ELSE 'FALSE'
END AS NewFiled
FROM TABLE1
If TABLE2.ID
is Unique or a Primary Key, you could also use this:
SELECT
TABEL1.Id,
CASE WHEN TABLE2.ID IS NOT NULL
THEN 'TRUE'
ELSE 'FALSE'
END AS NewFiled
FROM TABLE1
LEFT JOIN Table2
ON TABLE2.ID = TABLE1.ID
var cumulativeOffset = function(element) {
var top = 0, left = 0;
do {
top += element.offsetTop || 0;
left += element.offsetLeft || 0;
element = element.offsetParent;
} while(element);
return {
top: top,
left: left
};
};

For retrieving data using Ajax + jQuery, you should write the following code:
<html>
<script type="text/javascript" src="jquery-1.3.2.js"> </script>
<script type="text/javascript">
$(document).ready(function() {
$("#display").click(function() {
$.ajax({ //create an ajax request to display.php
type: "GET",
url: "display.php",
dataType: "html", //expect html to be returned
success: function(response){
$("#responsecontainer").html(response);
//alert(response);
}
});
});
});
</script>
<body>
<h3 align="center">Manage Student Details</h3>
<table border="1" align="center">
<tr>
<td> <input type="button" id="display" value="Display All Data" /> </td>
</tr>
</table>
<div id="responsecontainer" align="center">
</div>
</body>
</html>
For mysqli connection, write this:
<?php
$con=mysqli_connect("localhost","root","");
For displaying the data from database, you should write this :
<?php
include("connection.php");
mysqli_select_db("samples",$con);
$result=mysqli_query("select * from student",$con);
echo "<table border='1' >
<tr>
<td align=center> <b>Roll No</b></td>
<td align=center><b>Name</b></td>
<td align=center><b>Address</b></td>
<td align=center><b>Stream</b></td></td>
<td align=center><b>Status</b></td>";
while($data = mysqli_fetch_row($result))
{
echo "<tr>";
echo "<td align=center>$data[0]</td>";
echo "<td align=center>$data[1]</td>";
echo "<td align=center>$data[2]</td>";
echo "<td align=center>$data[3]</td>";
echo "<td align=center>$data[4]</td>";
echo "</tr>";
}
echo "</table>";
?>
What you call "Two-Way SSL" is usually called TLS/SSL with client certificate authentication.
In a "normal" TLS connection to example.com only the client verifies that it is indeed communicating with the server for example.com. The server doesn't know who the client is. If the server wants to authenticate the client the usual thing is to use passwords, so a client needs to send a user name and password to the server, but this happens inside the TLS connection as part of an inner protocol (e.g. HTTP) it's not part of the TLS protocol itself. The disadvantage is that you need a separate password for every site because you send the password to the server. So if you use the same password on for example PayPal and MyPonyForum then every time you log into MyPonyForum you send this password to the server of MyPonyForum so the operator of this server could intercept it and try it on PayPal and can issue payments in your name.
Client certificate authentication offers another way to authenticate the client in a TLS connection. In contrast to password login, client certificate authentication is specified as part of the TLS protocol. It works analogous to the way the client authenticates the server: The client generates a public private key pair and submits the public key to a trusted CA for signing. The CA returns a client certificate that can be used to authenticate the client. The client can now use the same certificate to authenticate to different servers (i.e. you could use the same certificate for PayPal and MyPonyForum without risking that it can be abused). The way it works is that after the server has sent its certificate it asks the client to provide a certificate too. Then some public key magic happens (if you want to know the details read RFC 5246) and now the client knows it communicates with the right server, the server knows it communicates with the right client and both have some common key material to encrypt and verify the connection.

Use value="<?php if (isset($firstname) && $success == '') {echo $firstname;} ?>"
You'll then have to create the $success variable--as I did in my example.
My experience with Excel 2010 on WinXP with French regional settings
It's possible to make the multiple transitions set with different values for duration, delay and timing function. To split different transitions use ,
button{
transition: background 1s ease-in-out 2s, width 2s linear;
-webkit-transition: background 1s ease-in-out 2s, width 2s linear; /* Safari */
}

Try setting the timeout value in your web service proxy class:
WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds
CORS is Cross Origin Resource Sharing, you get this error if you are trying to access from one domain to another domain.
Try using JSONP. In your case, JSONP should work fine because it only uses the GET method.
Try something like this:
var url = "https://api.getevents.co/event?&lat=41.904196&lng=12.465974";
$http({
method: 'JSONP',
url: url
}).
success(function(status) {
//your code when success
}).
error(function(status) {
//your code when fails
});
I use apache version 2.4.27, also have this problem, solved it through modify
the conf/extra/httpdahssl.conf,comment the 18 line content(Listen 443 https),it works fine.
I found and used (successfully) this fix:
# Fix it with symlinks in /usr/bin
$ cd /usr/bin/
$ sudo ln -s /[path/to/git]/bin/git* .
