A simple one would be

\d{4}-\d{2}-\d{2}

Debuggex Demo

but this does not restrict month to 1-12 and days from 1 to 31.

There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.

Loose type checking

Easy to write, but 0, '', false, null and undefined will be converted to default value, which might not be expected outcome.

function myFunc(requiredArg, optionalArg) {
    optionalArg = optionalArg || 'defaultValue';
}

Strict type checking

Longer, but covers majority of cases. Only case where it incorrectly assigns default value is when we pass undefined as parameter.

function myFunc(requiredArg, optionalArg) {
    optionalArg = typeof optionalArg !== 'undefined' ? optionalArg : 'defaultValue';
}

Checking arguments variable

Catches all cases but is the most clumsy to write.

function myFunc(requiredArg, optionalArg1, optionalArg2) {
    optionalArg1 = arguments.length > 1 ? optionalArg1 : 'defaultValue';
    optionalArg2 = arguments.length > 2 ? optionalArg2 : 'defaultValue';
}

ES6

Unfortunately this has very poor browser support at the moment

function myFunc(requiredArg, optionalArg = 'defaultValue') {

}

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

You have to change the values in the CATALINA_OPTS option defined in the Tomcat Catalina start file. To increase the PermGen memory change the value of the MaxPermSize variable, otherwise change the value of the Xmx variable.

Linux & Mac OS: Open or create setenv.sh file placed in the "bin" directory. You have to apply the changes to this line:

export CATALINA_OPTS="$CATALINA_OPTS -server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"

Windows:

Open or create the setenv.bat file placed in the "bin" directory:

set CATALINA_OPTS=-server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m

.getMonth() returns a zero-based number so to get the correct month you need to add 1, so calling .getMonth() in may will return 4 and not 5.

So in your code we can use currentdate.getMonth()+1 to output the correct value. In addition:

• .getDate() returns the day of the month <- this is the one you want
• .getDay() is a separate method of the Date object which will return an integer representing the current day of the week (0-6) 0 == Sunday etc

so your code should look like this:

var currentdate = new Date(); 
var datetime = "Last Sync: " + currentdate.getDate() + "/"
                + (currentdate.getMonth()+1)  + "/" 
                + currentdate.getFullYear() + " @ "  
                + currentdate.getHours() + ":"  
                + currentdate.getMinutes() + ":" 
                + currentdate.getSeconds();

JavaScript Date instances inherit from Date.prototype. You can modify the constructor's prototype object to affect properties and methods inherited by JavaScript Date instances

You can make use of the Date prototype object to create a new method which will return today's date and time. These new methods or properties will be inherited by all instances of the Date object thus making it especially useful if you need to re-use this functionality.

// For todays date;
Date.prototype.today = function () { 
    return ((this.getDate() < 10)?"0":"") + this.getDate() +"/"+(((this.getMonth()+1) < 10)?"0":"") + (this.getMonth()+1) +"/"+ this.getFullYear();
}

// For the time now
Date.prototype.timeNow = function () {
     return ((this.getHours() < 10)?"0":"") + this.getHours() +":"+ ((this.getMinutes() < 10)?"0":"") + this.getMinutes() +":"+ ((this.getSeconds() < 10)?"0":"") + this.getSeconds();
}

You can then simply retrieve the date and time by doing the following:

var newDate = new Date();
var datetime = "LastSync: " + newDate.today() + " @ " + newDate.timeNow();

Or call the method inline so it would simply be -

var datetime = "LastSync: " + new Date().today() + " @ " + new Date().timeNow();

var inputs = document.querySelectorAll("input[type=text]") ||
(function() {
    var ret=[], elems = document.getElementsByTagName('input'), i=0,l=elems.length;
    for (;i<l;i++) {
        if (elems[i].type.toLowerCase() === "text") {
            ret.push(elems[i]);
        }
    }

    return ret;
}());

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

From my programming archive:

function querystring(key) {
   var re=new RegExp('(?:\\?|&)'+key+'=(.*?)(?=&|$)','gi');
   var r=[], m;
   while ((m=re.exec(document.location.search)) != null) r[r.length]=m[1];
   return r;
}

If the value doesn't exist, an empty array is returned.
If the value exists, an array is return that has one item, the value.
If several values with the name exists, an array containing each value is returned.

Examples:

var param1var = querystring("param1")[0];

document.write(querystring("name"));

if (querystring('id')=='42') alert('We apoligize for the inconvenience.');

if (querystring('button').length>0) alert(querystring('info'));

Is very easy, this work for me:

PHP:

set_time_limit(300); // Time in seconds, max_execution_time

Here is the PHP documentation

Thanks to user1354692 I could made it more easy, with only one line! the one he has commented:

try {
    File file = new File(Environment.getExternalStorageDirectory(), String.valueOf(System.currentTimeMillis()));
    Runtime.getRuntime().exec("logcat -d -v time -f " + file.getAbsolutePath());}catch (IOException e){}

Also do note when specifying DATETIME as DATETIME(3) or like on MySQL 5.7.x, you also have to add the same value for CURRENT_TIMESTAMP(3). If not it will keep throwing 'Invalid default value'.

I got the same error from having two references to different versions of jQuery.

In my master page:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>

And also on the page:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"> </script>

Redirecting stderr to stdout seems to also do the trick without any other commands/scriptblock wrappers although I can't find an explanation why it works that way..

# test.ps1

$ErrorActionPreference = "Stop"

aws s3 ls s3://xxx
echo "==> pass"

aws s3 ls s3://xxx 2>&1
echo "shouldn't be here"

This will output the following as expected (the command aws s3 ... returns $LASTEXITCODE = 255)

PS> .\test.ps1

An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied
==> pass

What is this for and why would I use @":\" instead of ":\"?

Because when you have a long string with many \ you don't need to escape them all and the \n, \r and \f won't work too.

This is an old post but for those who are interested:

If you want to change the default port number so when you run the "runserver" command you start with your preferred port do this:

1. Find your python installation. (you can have multiple pythons installed and you can have your virtual environment version as well so make sure you find the right one)
2. Inside the python folder locate the site-packages folder. Inside that you will find your django installation
3. Open the django folder-> core -> management -> commands
4. Inside the commands folder open up the runserver.py script with a text editor
5. Find the DEFAULT_PORT field. it is equal to 8000 by default. Change it to whatever you like DEFAULT_PORT = "8080"
6. Restart your server: python manage.py runserver and see that it uses your set port number

It works with python 2.7 but it should work with newer versions of python as well. Good luck

I'd cut and paste the original SP and delete all columns except the 2 you want. Or. I'd bring the result set back, map it to a proper business object, then LINQ out the two columns.

In my opinion it would be better to keep the logic in the controller and pass it to the view to use. This can be done one of two ways using the 'View::make' method. I am currently using Laravel 3 but I am pretty sure that it is the same way in Laravel 4.

public function action_hello($userName)
{
    return View::make('hello')->with('name', $userName);
}

or

public function action_hello($first, $last)
{
    $data = array(
        'forename'  => $first,
        'surname' => $last
    );
    return View::make('hello', $data);
}

The 'with' method is chainable. You would then use the above like so:

<p>Hello {{$name}}</p>

You can use the CHARINDEX and specify the starting location:

  ,CHARINDEX('-',@x,CHARINDEX('-',@x, (CHARINDEX('-',@x)+1))+1) ThirdIndexOf
  ,CHARINDEX('-',REVERSE(LTRIM(RTRIM(@x)))) LastIndexOf;

Just for other's reference, I just received this and found it was due to AngularJS. It's for backwards compatibility:

if (!event.preventDefault) {
    event.preventDefault = function() {
        event.returnValue = false; //ie
    };
}

As nearly all of the answers to this question have been unsatisfactory or plainly don't work in my situation, I have authored AnyClone which is entirely implemented with reflection and solved all of the needs here. I was unable to get serialization to work in a complicated scenario with complex structure, and IClonable is less than ideal - in fact it shouldn't even be necessary.

Standard ignore attributes are supported using [IgnoreDataMember], [NonSerialized]. Supports complex collections, properties without setters, readonly fields etc.

I hope it helps someone else out there who ran into the same problems I did.

For this example we take it for granted that varcharcol doesn't contain '' and have no empty cell against this column

select * from some_table where varcharCol = ''
select * from some_table where varcharCol like ''

The first one results in 0 row output while the second one shows the whole list. = is strictly-match case while like acts like a filter. if filter has no criteria, every data is valid.

like - by the virtue of its purpose works a little slower and is intended for use with varchar and similar data.

$(this).parent().css('z-index',3000);

Try adding this to your where clause:

dateadd(day, -30, getdate())

add this code in .htaccess (as an alternative of php.ini / ini_set function):

<IfModule mod_php5.c>
php_flag log_errors on 
php_value error_log ./path_to_MY_PHP_ERRORS.log
# php_flag display_errors on 
</IfModule>

* as commented: this is for Apache-type servers, and not for Nginx or others.

Why nobody wrote this simple way of converting JSON string in List ?

List<Object> list = Arrays.asList(new GsonBuilder().create().fromJson(jsonString, Object[].class));

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

The jQuery API documentation lists live() as deprecated as of version 1.7 and removed as of version 1.9: link.

version deprecated: 1.7, removed: 1.9

Furthermore it states:

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live()

Offering an interactive sort handling multiple columns is nothing trivial.

Unless you want to write a good amount of code handling logic for multiple row clicks, editing and refreshing page content, managing sort algorithms for large tables… then you really are better off adopting a plug-in.

tablesorter, (with updates by Mottie) is my favorite. It’s easy to get going and very customizable. Just add the class tablesorter to the table you want to sort, then invoke the tablesorter plugin in a document load event:

$(function(){
    $("#myTable").tablesorter();
});

You can browse the documentation to learn about advanced features.

Collection literals didn't make it into Java 8, but it is possible to use the Stream API to initialize a list in one rather long line:

List<String> places = Stream.of("Buenos Aires", "Córdoba", "La Plata").collect(Collectors.toList());

If you need to ensure that your List is an ArrayList:

ArrayList<String> places = Stream.of("Buenos Aires", "Córdoba", "La Plata").collect(Collectors.toCollection(ArrayList::new));

Just came across this question, and wanted to suggest an alternate approach.

In the markup the OP provided, there is a click event binding. This makes me think that the elements are being used as "buttons". If that is the case, they could be marked up as <button> elements and styled like links, if that is the look you desire. (For example, Bootstrap has a built-in "link" button style, https://v4-alpha.getbootstrap.com/components/buttons/#examples)

This has several direct and indirect benefits. It allows you to bind to the disabled property, which when set will disable mouse and keyboard events automatically. It lets you style the disabled state based on the disabled attribute, so you don't have to also manipulate the element's class. It is also better for accessibility.

For a good write-up about when to use buttons and when to use links, see Links are not buttons. Neither are DIVs and SPANs

When you use Object.defineProperties, by default writable is set to false, so _year and edition are actually read only properties.

Explicitly set them to writable: true:

_year: {
    value: 2004,
    writable: true
},

edition: {
    value: 1,
    writable: true
},

Check out MDN for this method.

writable
true if and only if the value associated with the property may be changed with an assignment operator.
Defaults to false.

declare @date date=getdate()
declare @st_date date,@end_dt date
set @st_date=convert(varchar(5),year(@date))+'-'+convert(varchar(5),month(@date))+'-01'
set @end_dt=DATEADD(day,-1, DATEADD(month,1,@st_date))
---------**************--------------
select @st_date as [START DATE],@end_dt AS [END DATE]

This solution dose not use regex, supports accented characters and also supported by almost every browser.

function capitalizeIt(str) {

The site generates a unique token when it makes the form page. This token is required to post/get data back to the server.

Since the token is generated by your site and provided only when the page with the form is generated, some other site can't mimic your forms -- they won't have the token and therefore can't post to your site.

setprecision(n) applies to the entire number, not the fractional part. You need to use the fixed-point format to make it apply to the fractional part: setiosflags(ios::fixed)

If you want to pass props to a component inside a route, the simplest way is by utilizing the render, like this:

<Route exact path="/details/:id" render={(props) => <DetailsPage globalStore={globalStore} {...props} /> } />

You can access the props inside the DetailPage using:

this.props.match
this.props.globalStore

The {...props} is needed to pass the original Route's props, otherwise you will only get this.props.globalStore inside the DetailPage.

You can also use Comparator.comparing(Function, Comparator)
It is convenient to chain comparators when necessary, e.g.:

Comparator<SomeEntity> ENTITY_COMPARATOR = comparing(SomeEntity::getProperty1, reverseOrder())
        .thenComparingInt(SomeEntity::getProperty2)
        .thenComparing(SomeEntity::getProperty3, reverseOrder());

If you need something from super's __init__ to be done in addition to what is being done in the current class's __init__, you must call it yourself, since that will not happen automatically. But if you don't need anything from super's __init__, no need to call it. Example:

>>> class C(object):
        def __init__(self):
            self.b = 1


>>> class D(C):
        def __init__(self):
            super().__init__() # in Python 2 use super(D, self).__init__()
            self.a = 1


>>> class E(C):
        def __init__(self):
            self.a = 1


>>> d = D()
>>> d.a
1
>>> d.b  # This works because of the call to super's init
1
>>> e = E()
>>> e.a
1
>>> e.b  # This is going to fail since nothing in E initializes b...
Traceback (most recent call last):
  File "<pyshell#70>", line 1, in <module>
    e.b  # This is going to fail since nothing in E initializes b...
AttributeError: 'E' object has no attribute 'b'

__del__ is the same way, (but be wary of relying on __del__ for finalization - consider doing it via the with statement instead).

I rarely use __new__. I do all the initialization in __init__.

also works if you do a "display: block;" on the td, destroying the td identity, but works!

There's a special function n() in dplyr to count rows (potentially within groups):

library(dplyr)
mtcars %>% 
  group_by(cyl, gear) %>% 
  summarise(n = n())
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

But dplyr also offers a handy count function which does exactly the same with less typing:

count(mtcars, cyl, gear)          # or mtcars %>% count(cyl, gear)
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

Is there any reason for a class declaration to inherit from object?

In Python 3, apart from compatibility between Python 2 and 3, no reason. In Python 2, many reasons.

Python 2.x story:

In Python 2.x (from 2.2 onwards) there's two styles of classes depending on the presence or absence of object as a base-class:

1. "classic" style classes: they don't have object as a base class:

   >>> class ClassicSpam:      # no base class
   ...     pass
   >>> ClassicSpam.__bases__
   ()
   

2. "new" style classes: they have, directly or indirectly (e.g inherit from a built-in type), object as a base class:

   >>> class NewSpam(object):           # directly inherit from object
   ...    pass
   >>> NewSpam.__bases__
   (<type 'object'>,)
   >>> class IntSpam(int):              # indirectly inherit from object...
   ...    pass
   >>> IntSpam.__bases__
   (<type 'int'>,) 
   >>> IntSpam.__bases__[0].__bases__   # ... because int inherits from object  
   (<type 'object'>,)
   

Without a doubt, when writing a class you'll always want to go for new-style classes. The perks of doing so are numerous, to list some of them:

• Support for descriptors. Specifically, the following constructs are made possible with descriptors:

  1. classmethod: A method that receives the class as an implicit argument instead of the instance.
  2. staticmethod: A method that does not receive the implicit argument self as a first argument.
  3. properties with property: Create functions for managing the getting, setting and deleting of an attribute.
  4. __slots__: Saves memory consumptions of a class and also results in faster attribute access. Of course, it does impose limitations.

• The __new__ static method: lets you customize how new class instances are created.

• Method resolution order (MRO): in what order the base classes of a class will be searched when trying to resolve which method to call.

• Related to MRO, super calls. Also see, super() considered super.

If you don't inherit from object, forget these. A more exhaustive description of the previous bullet points along with other perks of "new" style classes can be found here.

One of the downsides of new-style classes is that the class itself is more memory demanding. Unless you're creating many class objects, though, I doubt this would be an issue and it's a negative sinking in a sea of positives.

Python 3.x story:

In Python 3, things are simplified. Only new-style classes exist (referred to plainly as classes) so, the only difference in adding object is requiring you to type in 8 more characters. This:

class ClassicSpam:
    pass

is completely equivalent (apart from their name :-) to this:

class NewSpam(object):
     pass

and to this:

class Spam():
    pass

All have object in their __bases__.

>>> [object in cls.__bases__ for cls in {Spam, NewSpam, ClassicSpam}]
[True, True, True]

So, what should you do?

In Python 2: always inherit from object explicitly. Get the perks.

In Python 3: inherit from object if you are writing code that tries to be Python agnostic, that is, it needs to work both in Python 2 and in Python 3. Otherwise don't, it really makes no difference since Python inserts it for you behind the scenes.

I use this function which uses bc and thus supports floating point calculations:

c () { 
    local a
    (( $# > 0 )) && a="$@" || read -r -p "calc: " a
    bc -l <<< "$a"
}

Example:

$ c '5*5'
25
$ c 5/5
1.00000000000000000000
$ c 3.4/7.9
.43037974683544303797

Bash's arithmetic expansion doesn't support floats (but Korn shell and zsh do).

Example:

$ ksh -c 'echo "$((3.0 / 4))"'
0.75

You can use also

select * from tablename where column1 ='a' and column2!='b';

For all of those, who still experiencing this problem, I just spent 2 days tracking down the bloody thing. I was getting the same error when there was no rows in dataset. Seems obvious, but error message is very obscure, hence 2 days.

You can use my libary called RDALogger. Here is github link.

With this library, you can log your message with method name/class name/line number and anchor link. With this link, when you click log, screen goes to this line of code.

To use library, you must do implementations below.

in root level gradle

allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

in app level gradle

dependencies {
            implementation 'com.github.ardakaplan:RDALogger:1.0.0'
    }

For initializing library, you should start like this (in Application.class or before first use)

RDALogger.start("TAG NAME").enableLogging(true);

And than you can log whatever you want;

    RDALogger.info("info");
    RDALogger.debug("debug");
    RDALogger.verbose("verbose");
    RDALogger.warn("warn");
    RDALogger.error("error");
    RDALogger.error(new Throwable());
    RDALogger.error("error", new Throwable());

And finally output shows you all you want (class name, method name, anchor link, message)

08-09 11:13:06.023 20025-20025/com.ardakaplan.application I/Application: IN CLASS : (ENApplication.java:29)   ///   IN METHOD : onCreate
    info

Often when people are looking for "timezones", what will suffice is just "UTC offset". e.g., their server is in UTC+5 and they want to know that their client is running in UTC-8.

In plain old javascript (new Date()).getTimezoneOffset()/60 will return the current number of hours offset from UTC.

It's worth noting a possible "gotcha" in the sign of the getTimezoneOffset() return value (from MDN docs):

The time-zone offset is the difference, in minutes, between UTC and local time. Note that this means that the offset is positive if the local timezone is behind UTC and negative if it is ahead. For example, for time zone UTC+10:00 (Australian Eastern Standard Time, Vladivostok Time, Chamorro Standard Time), -600 will be returned.

However, I recommend you use the day.js for time/date related Javascript code. In which case you can get an ISO 8601 formatted UTC offset by running:

> dayjs().format("Z")
"-08:00"

It probably bears mentioning that the client can easily falsify this information.

(Note: this answer originally recommended https://momentjs.com/, but dayjs is a more modern, smaller alternative.)

If I understand the question, you may interested in this example in the Matplotlib gallery.

Yann's comment above provides a similar example.

Edit - Link above fixed. Corresponding code copied from the Matplotlib gallery:

from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt

host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)

par1 = host.twinx()
par2 = host.twinx()

offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right", axes=par2,
                                        offset=(offset, 0))

par2.axis["right"].toggle(all=True)

host.set_xlim(0, 2)
host.set_ylim(0, 2)

host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity")

par1.set_ylim(0, 4)
par2.set_ylim(1, 65)

host.legend()

host.axis["left"].label.set_color(p1.get_color())
par1.axis["right"].label.set_color(p2.get_color())
par2.axis["right"].label.set_color(p3.get_color())

plt.draw()
plt.show()

#plt.savefig("Test")

I think it's a good idea to keep avoiding modules unless you stick them into separate namespaces. Because in Intellisense methods in modules will be visible from everywhere in that namespace.

So instead of ModuleName.MyMethod() you end up with MyMethod() popups in anywhere and this kind of invalidates the encapsulation. (at least in the programming level).

That's why I always try to create Class with shared methods, seems so much better.

For 4.x version

$('#select2Id').val(__INDEX__).trigger('change');

to select value with INDEX

$('#select2Id').val('').trigger('change');

to select nothing (show placeholder if it is)

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Update: Nowadays installing is done with pip, but libyaml is still required to build the C extension (on mac):

brew install libyaml
python -m pip install pyyaml

Outdated method:

For MacOSX (mavericks), the following seems to work:

brew install libyaml
sudo python -m easy_install pyyaml

I've personally never seen .cc in any project that I've worked on, but in all technicality the compiler won't care.

Who will care is the developers working on your source, so my rule of thumb is to go with what your team is comfortable with. If your "team" is the open source community, go with something very common, of which .cpp seems to be the favourite.

You can use the DataGridView refresh method. But... in a lot of cases you have to refresh the DataGridView from methods running on a different thread than the one where the DataGridView is running. In order to do that you should implement the following method and call it rather than directly typing DataGridView.Refresh():

    private void RefreshGridView()
    {
        if (dataGridView1.InvokeRequired)
        {
            dataGridView1.Invoke((MethodInvoker)delegate ()
            {
                RefreshGridView();
            });
        }
        else
            dataGridView1.Refresh();
    }  

you can use update from...

something like:

update shipment set.... from shipment inner join ProfilerTest.dbo.BookingDetails on ...

double totalMinutes = (end-start).TotalMinutes;

With any sensible compiler, you should observe no difference; they should be compiled to identical machine code as they're equivalent.

To embed this in your script, you can do it like this:

        Write-Output $server.name | Out-File '(Your Path)\Servers.txt' -Append

That should do the trick.

I would like to share what I understood from this keyword. This keyword has 6 usages in java as follows:-

1. It can be used to refer to the current class variable. Let us understand with a code.*

Let's understand the problem if we don't use this keyword by the example given below:

class Employee{  
int id_no;  
String name;  
float salary;  
Student(int id_no,String name,float salary){  
id_no = id_no;  
name=name;  
salary = salary;  
}  
void display(){System.out.println(id_no +" "+name+" "+ salary);}  
}  
class TestThis1{  
public static void main(String args[]){  
Employee s1=new Employee(111,"ankit",5000f);  
Employee s2=new Employee(112,"sumit",6000f);  
s1.display();  
s2.display();  
}}  

Output:-

0 null 0.0
0 null 0.0

In the above example, parameters (formal arguments) and instance variables are same. So, we are using this keyword to distinguish local variable and instance variable.

class Employee{  
int id_no;  
String name;  
float salary;  
Student(int id_no,String name,float salary){  
this.id_no = id_no;  
this.name=name;  
this.salary = salary;  
}  
void display(){System.out.println(id_no +" "+name+" "+ salary);}  
}  
class TestThis1{  
public static void main(String args[]){  
Employee s1=new Employee(111,"ankit",5000f);  
Employee s2=new Employee(112,"sumit",6000f);  
s1.display();  
s2.display();  
}} 

output:

111 ankit 5000
112 sumit 6000

2. To invoke the current class method.

class A{  
void m(){System.out.println("hello Mandy");}  
void n(){  
System.out.println("hello Natasha");  
//m();//same as this.m()  
this.m();  
}  
}  
class TestThis4{  
public static void main(String args[]){  
A a=new A();  
a.n();  
}}  

Output:

hello Natasha
hello Mandy

3. to invoke the current class constructor. It is used to constructor chaining.

class A{  
A(){System.out.println("hello ABCD");}  
A(int x){  
this();  
System.out.println(x);  
}  
}  
class TestThis5{  
public static void main(String args[]){  
A a=new A(10);  
}}

Output:

hello ABCD
10

4. to pass as an argument in the method.

class S2{  
  void m(S2 obj){  
  System.out.println("The method is invoked");  
  }  
  void p(){  
  m(this);  
  }  
  public static void main(String args[]){  
  S2 s1 = new S2();  
  s1.p();  
  }  
}  

Output:

The method is invoked

5. to pass as an argument in the constructor call

class B{  
  A4 obj;  
  B(A4 obj){  
    this.obj=obj;  
  }  
  void display(){  
    System.out.println(obj.data);//using data member of A4 class  
  }  
}  

class A4{  
  int data=10;  
  A4(){  
   B b=new B(this);  
   b.display();  
  }  
  public static void main(String args[]){  
   A4 a=new A4();  
  }  
} 

Output:-

10

6. to return current class instance

class A{  
A getA(){  
return this;  
}  
void msg(){System.out.println("Hello");}  
}  
class Test1{  
public static void main(String args[]){  
new A().getA().msg();  
}  
}  

Output:-

Hello

Also, this keyword cannot be used without .(dot) as it's syntax is invalid.

You can directly use String.valueOf()

String.valueOf(charSequence)

Though this is same as toString() it does a null check on the charSequence before actually calling toString.

This is useful when a method can return either a charSequence or null value.

function pageLoad() {
    console.log('pageLoad');
    $(document).ready(function () {
        alert("hi");
    });
};

its the ScriptManager ajax making the problem use pageLoad() instead

Eclipse Photon user here, found it under the toolbar's Windows > Preferences > Install/Update > "Uninstall or update" link > Click stuff and hit the "Uninstall" button.

This is to help fill in the gaps in Adrien Plisson's answer (which should be upvoted as soon as he edits it ;-):

you can also get the fully qualified path of your first argument by using %~f1, but this gives a path according to the current path, which is obviously not what you want.

unfortunately, i don't know how to mix the 2 together...

One can handle %0 and %1 likewise:

• %~dpnx0 for fully qualified drive+path+name+extension of the batchfile itself,
  %~f0 also suffices;
• %~dpnx1 for fully qualified drive+path+name+extension of its first argument [if that's a filename at all],
  %~f1 also suffices;

%~f1 will work independent of how you did specify your first argument: with relative paths or with absolute paths (if you don't specify the file's extension when naming %1, it will not be added, even if you use %~dpnx1 -- however.

But how on earth would you name a file on a different drive anyway if you wouldn't give that full path info on the commandline in the first place?

However, %~p0, %~n0, %~nx0 and %~x0 may come in handy, should you be interested in path (without driveletter), filename (without extension), full filename with extension or filename's extension only. But note, while %~p1 and %~n1 will work to find out the path or name of the first argument, %~nx1 and %~x1 will not add+show the extension, unless you used it on the commandline already.

Its my code

jQuery(document).ready(function(e) {
    var WindowHeight = jQuery(window).height();

    var load_element = 0;

    //position of element
    var scroll_position = jQuery('.product-bottom').offset().top;

    var screen_height = jQuery(window).height();
    var activation_offset = 0;
    var max_scroll_height = jQuery('body').height() + screen_height;

    var scroll_activation_point = scroll_position - (screen_height * activation_offset);

    jQuery(window).on('scroll', function(e) {

        var y_scroll_pos = window.pageYOffset;
        var element_in_view = y_scroll_pos > scroll_activation_point;
        var has_reached_bottom_of_page = max_scroll_height <= y_scroll_pos && !element_in_view;

        if (element_in_view || has_reached_bottom_of_page) {
            jQuery('.product-bottom').addClass("change");
        } else {
            jQuery('.product-bottom').removeClass("change");
        }

    });

});

Its working Fine

http://joda-time.sourceforge.net/quickstart.html

Each datetime class provides a variety of constructors. These include the Object constructor. This allows you to construct, for example, DateTime from the following objects:

* Date - a JDK instant
* Calendar - a JDK calendar
* String - in ISO8601 format
* Long - in milliseconds
* any Joda-Time datetime class

What about using eventlet? If you want to timeout the request after 10 seconds, even if data is being received, this snippet will work for you:

import requests
import eventlet
eventlet.monkey_patch()

with eventlet.Timeout(10):
    requests.get("http://ipv4.download.thinkbroadband.com/1GB.zip", verify=False)

each passes into your function index and element. Check index against the length of the set and you're good to go:

var set = $('.requiredText');
var length = set.length;
set.each(function(index, element) {
      thisVal = $(this).val();
      if(parseInt(thisVal) !== 0) {
          console.log('Valid Field: ' + thisVal);
          if (index === (length - 1)) {
              console.log('Last field, submit form here');
          }
      }
});

You want huge?

Here's a small table: create table foo (id int not null primary key auto_increment, crap char(2000));

insert into foo(crap) values ('');

-- each time you run the next line, the number of rows in foo doubles. insert into foo( crap ) select * from foo;

run it twenty more times, you have over a million rows to play with.

Yes, if he's looking for looks of relations to navigate, this is not the answer. But if by huge he means to test performance and his ability to optimize, this will do it. I did exactly this (and then updated with random values) to test an potential answer I had for another question. (And didn't answer it, because I couldn't come up with better performance than what that asker had.)

Had he asked for "complex", I'd have gien a differnt answer. To me,"huge" implies "lots of rows".

Because you don't need huge to play with tables and relations. Consider a table, by itself, with no nullable columns. How many different kinds of rows can there be? Only one, as all columns must have some value as none can be null.

Every nullable column multiples by two the number of different kinds of rows possible: a row where that column is null, an row where it isn't null.

Now consider the table, not in isolation. Consider a table that is a child table: for every child that has an FK to the parent, that, is a many-to-one, there can be 0, 1 or many children. So we multiply by three times the count we got in the previous step (no rows for zero, one for exactly one, two rows for many). For any grandparent to which the parent is a many, another three.

For many-to-many relations, we can have have no relation, a one-to-one, a one-to-many, many-to-one, or a many-to-many. So for each many-to-many we can reach in a graph from the table, we multiply the rows by nine -- or just like two one-to manys. If the many-to-many also has data, we multiply by the nullability number.

Tables that we can't reach in our graph -- those that we have no direct or indirect FK to, don't multiply the rows in our table.

By recursively multiplying the each table we can reach, we can come up with the number of rows needed to provide one of each "kind", and we need no more than those to test every possible relation in our schema. And we're nowhere near huge.

lapply is probably a better choice than apply here, as apply first coerces your data.frame to an array which means all the columns must have the same type. Depending on your context, this could have unintended consequences.

The pattern is:

df[cols] <- lapply(df[cols], FUN)

The 'cols' vector can be variable names or indices. I prefer to use names whenever possible (it's robust to column reordering). So in your case this might be:

wifi[4:9] <- lapply(wifi[4:9], A)

An example of using column names:

wifi <- data.frame(A=1:4, B=runif(4), C=5:8)
wifi[c("B", "C")] <- lapply(wifi[c("B", "C")], function(x) -1 * x)

It's not too hard.

1. Drop a picturebox onto your form.
2. Add the .gif file as the image in the picturebox
3. Show the picturebox when you are loading.

Things to take into consideration:

• Disabling the picturebox will prevent the gif from being animated.

Animated gifs:

If you are looking for animated gifs you can generate them:

AjaxLoad - Ajax Loading gif generator

Another way of doing it:

Another way that I have found that works quite well is the async dialog control that I found on the code project

I struggled for a while about this. Stupid rule for __init__. It is two "_" together to be "__"

Create a bi-directional relationship, like this:

@Entity
public class Parent implements Serializable {

    @Id
    @GeneratedValue
    private long id;

    @OneToMany(mappedBy = "parent", cascade = CascadeType.REMOVE)
    private Set<Child> children;
}

If you need to use IE8, you can try this JavaScript library for vector graphics. It is like solving the "canvas" and "SVG" incompatibilities of IE8 at the same time.

Raphaël

I have just try it in a fast example and it works correctly. I don't know how legible is the source code but I hope it helps you. As they said in its site, the library is compatible with very old explorers.

Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+.

You can also use org.apache.commons.lang.ArrayUtils.isEquals()

Windows 10, Git v2.13.2

My .gitconfig. Remember to add escape character for '\' and '"'.

[diff]
    tool = bc4
[difftool]
    prompt = false
[difftool "bc4"]
    cmd = \"C:\\Program Files\\Beyond Compare 4\\BCompare.exe\" \"$LOCAL\" \"$REMOTE\"
[merge]
    tool = bc4
[mergetool "bc4"]
    path = C:\\Program Files\\Beyond Compare 4\\BCompare.exe

You may reference setting up beyond compare as difftool for using git commands to config it.

First() is causing this if your select returns 0 rows. You either have to catch that exception, or use FirstOrDefault() which will return null in case of no elements.

most of the time it happens when the table header count and data cel count is not matched

ImageMagick and GD can handle PNGs too; heck, you could even do stuff with nothing but gdk-pixbuf. Are you looking for a graphical editor, or scriptable/embeddable libraries?

I am not sure but as per my knowledge I share my views. I always accept best answer if I am wrong .

Alarm Manager

The Alarm Manager holds a CPU wake lock as long as the alarm receiver's onReceive() method is executing. This guarantees that the phone will not sleep until you have finished handling the broadcast. Once onReceive() returns, the Alarm Manager releases this wake lock. This means that the phone will in some cases sleep as soon as your onReceive() method completes. If your alarm receiver called Context.startService(), it is possible that the phone will sleep before the requested service is launched. To prevent this, your BroadcastReceiver and Service will need to implement a separate wake lock policy to ensure that the phone continues running until the service becomes available.

Note: The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler.

Timer

timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {

        synchronized public void run() {

            \\ here your todo;
            }

        }, TimeUnit.MINUTES.toMillis(1), TimeUnit.MINUTES.toMillis(1));

Timer has some drawbacks that are solved by ScheduledThreadPoolExecutor. So it's not the best choice

ScheduledThreadPoolExecutor.

You can use java.util.Timer or ScheduledThreadPoolExecutor (preferred) to schedule an action to occur at regular intervals on a background thread.

Here is a sample using the latter:

ScheduledExecutorService scheduler =
    Executors.newSingleThreadScheduledExecutor();

scheduler.scheduleAtFixedRate
      (new Runnable() {
         public void run() {
            // call service
         }
      }, 0, 10, TimeUnit.MINUTES);

So I preferred ScheduledExecutorService

But Also think about that if the updates will occur while your application is running, you can use a Timer, as suggested in other answers, or the newer ScheduledThreadPoolExecutor. If your application will update even when it is not running, you should go with the AlarmManager.

The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running.

Take note that if you plan on updating when your application is turned off, once every ten minutes is quite frequent, and thus possibly a bit too power consuming.

We have a simple argument in Pandas read_csv for this:

Use:

df = pd.read_csv('test.csv', na_filter= False)

Pandas documentation clearly explains how the above argument works.

Link

$ git push origin develop:master

or, more generally

$ git push <remote> <local branch name>:<remote branch to push into>

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

You can use this:

var isEmpty = function(obj) {
  return Object.keys(obj).length === 0;
}

or this:

function isEmpty(obj) {
  return !Object.keys(obj).length > 0;
}

You can also use this:

function isEmpty(obj) {
  for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
      return false;
  }

  return true;
}

If using underscore or jQuery, you can use their isEmpty or isEmptyObject calls.

//form/descendant::input[@type='submit']

In addition to the accepted answers above I created a generic 'groupBy' filter using the underscore.js library.

JSFiddle (updated): http://jsfiddle.net/TD7t3/

The filter

app.filter('groupBy', function() {
    return _.memoize(function(items, field) {
            return _.groupBy(items, field);
        }
    );
});

Note the 'memoize' call. This underscore method caches the result of the function and stops angular from evaluating the filter expression every time, thus preventing angular from reaching the digest iterations limit.

We apply our 'groupBy' filter on the teamPlayers scope variable, on the 'team' property. Our ng-repeat receives a combination of (key, values[]) that we can use in our following iterations.

Update June 11th 2014 I expanded the group by filter to account for the use of expressions as the key (eg nested variables). The angular parse service comes in quite handy for this:

The filter (with expression support)

app.filter('groupBy', function($parse) {
    return _.memoize(function(items, field) {
        var getter = $parse(field);
        return _.groupBy(items, function(item) {
            return getter(item);
        });
    });
});

The controller (with nested objects)

app.controller('homeCtrl', function($scope) {
    var teamAlpha = {name: 'team alpha'};
    var teamBeta = {name: 'team beta'};
    var teamGamma = {name: 'team gamma'};

    $scope.teamPlayers = [{name: 'Gene', team: teamAlpha},
                      {name: 'George', team: teamBeta},
                      {name: 'Steve', team: teamGamma},
                      {name: 'Paula', team: teamBeta},
                      {name: 'Scruath of the 5th sector', team: teamGamma}];
});

The html (with sortBy expression)

<li ng-repeat="(team, players) in teamPlayers | groupBy:'team.name'">
    {{team}}
    <ul>
        <li ng-repeat="player in players">
            {{player.name}}
        </li>
    </ul>
</li>

At https://github.com/golang/go/issues/44196 randall77 suggested

time.Now().Sub(time.Unix(0,0)).Milliseconds()

which exploits the fact that Go's time.Duration already have Milliseconds method.

Suppose that you have a string like this :

String mDate="2019-09-17T10:56:07.827088"

Now we want to change this String format separate date and time in Java and Kotlin.

JAVA:

we have a method for extract date :

public String getDate() {
    try {
        DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.US);
        Date date = dateFormat.parse(mDate);
        dateFormat = new SimpleDateFormat("MM/dd/yyyy", Locale.US);
        return dateFormat.format(date);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return null;
}

Return is this : 09/17/2019

And we have method for extract time :

public String getTime() {

    try {
        DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.US);
        Date date = dateFormat.parse(mCreatedAt);
        dateFormat = new SimpleDateFormat("h:mm a", Locale.US);
        return dateFormat.format(date);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return null;
}

Return is this : 10:56 AM

KOTLIN:

we have a function for extract date :

fun getDate(): String? {

    var dateFormat = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.US)
    val date = dateFormat.parse(mDate!!)
    dateFormat = SimpleDateFormat("MM/dd/yyyy", Locale.US)
    return dateFormat.format(date!!)
}

Return is this : 09/17/2019

And we have method for extract time :

fun getTime(): String {

    var dateFormat = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.US)
    val time = dateFormat.parse(mDate!!)
    dateFormat = SimpleDateFormat("h:mm a", Locale.US)
    return dateFormat.format(time!!)
}

Return is this : 10:56 AM

Try to understand through this below function using python3

def floating_decimals(f_val, dec):
    prc = "{:."+str(dec)+"f}" #first cast decimal as str
    print(prc) #str format output is {:.3f}
    return prc.format(f_val)


print(floating_decimals(50.54187236456456564, 3))

Output is : 50.542

Hope this helps you!

     //controller  You can use this way

    public ActionResult Index()
    {
      List<Fund> fundList = db.Funds.ToList();
     ViewBag.Funds = fundList;
        return View();
    }




<--View ; You can use this way html-->

@foreach (var item in (List<Fund>)ViewBag.Funds)
{
    <p>@item.firtname</p>
}

Though it may be unrelated to your question, take a look at GetGUIThreadInfo Function.

You can easily achieve this using ArrayField:

# in my models...
tags = ArrayField(models.CharField(null=True, blank=True, max_length=100, choices=SECTORS_TAGS_CHOICES), blank=True, default=list)

# in my forms...
class MyForm(forms.ModelForm):

    class Meta:
        model = ModelClass
        fields = [..., 'tags', ...]

I use tagsinput JS library to render my tags but you can use whatever you like: This my template for this widget:

{% if not hidelabel and field.label %}<label for="{{ field.id_for_label }}">{{ field.label }}</label>{% endif %}
<input id="{{ field.id_for_label }}" type="text" name="{{ field.name }}" data-provide="tagsinput"{% if field.value %} value="{{ field.value }}"{% endif %}{% if field.field.disabled %} disabled{% endif %}>
{% if field.help_text %}<small id="{{ field.name }}-help-text" class="form-text text-muted">{{ field.help_text | safe }}</small>{% endif %}

Correctly overridden toString method can help in logging and debugging of Java.

The query execution happens on all get methods like

$this->db->get('table_name');
$this->db->get_where('table_name',$array);

While last_query contains the last query which was run

$this->db->last_query();

If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions

public function _compile_select($select_override = FALSE)
public function _reset_select()

Now you can write query and get it in a variable

$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();

Now reset query so if you want to write another query the object will be cleared.

$this->db->_reset_select();

And the thing is done. Cheers!!! Note : While using this way you must use

$this->db->from('myTable')

instead of

$this->db->get('myTable')

which runs the query.

Take a look at this example

If you're using Weebly, start by viewing the published site and right-clicking the image to Copy Image Address. Then in Weebly, go to Edit Site, Pages, click the page you wish to use, SEO Settings, under Header Code enter the code from Shef's answer:

<meta property="og:image" content="/uploads/..." />

just replacing /uploads/... with the copied image address. Click Publish to apply the change.

You can skip the part of Shef's answer about namespace, because that's already set by default in Weebly.

Factory and Service is a just wrapper of a provider.

Factory

Factory can return anything which can be a class(constructor function), instance of class, string, number or boolean. If you return a constructor function, you can instantiate in your controller.

 myApp.factory('myFactory', function () {

  // any logic here..

  // Return any thing. Here it is object
  return {
    name: 'Joe'
  }
}

Service

Service does not need to return anything. But you have to assign everything in this variable. Because service will create instance by default and use that as a base object.

myApp.service('myService', function () {

  // any logic here..

  this.name = 'Joe';
}

Actual angularjs code behind the service

function service(name, constructor) {
    return factory(name, ['$injector', function($injector) {
        return $injector.instantiate(constructor);
    }]);
}

It just a wrapper around the factory. If you return something from service, then it will behave like Factory.

IMPORTANT: The return result from Factory and Service will be cache and same will be returned for all controllers.

When should i use them?

Factory is mostly preferable in all cases. It can be used when you have constructor function which needs to be instantiated in different controllers.

Service is a kind of Singleton Object. The Object return from Service will be same for all controller. It can be used when you want to have single object for entire application. Eg: Authenticated user details.

find is the common tool for this kind of task :

find ./my_dir -mtime +10 -type f -delete

EXPLANATIONS

• ./my_dir your directory (replace with your own)
• -mtime +10 older than 10 days
• -type f only files
• -delete no surprise. Remove it to test your find filter before executing the whole command

And take care that ./my_dir exists to avoid bad surprises !

Angular only points to src/assets folder, nothing else is public to access via url so you should use full path

 this.fullImagePath = '/assets/images/therealdealportfoliohero.jpg'

Or

 this.fullImagePath = 'assets/images/therealdealportfoliohero.jpg'

This will only work if the base href tag is set with /

You can also add other folders for data in angular/cli. All you need to modify is angular-cli.json

"assets": [
 "assets",
 "img",
 "favicon.ico",
 ".htaccess"
]

Note in edit : Dist command will try to find all attachments from assets so it is also important to keep the images and any files you want to access via url inside assets, like mock json data files should also be in assets.

Git detects renames rather than persisting the operation with the commit, so whether you use git mv or mv doesn't matter.

The log command takes a --follow argument that continues history before a rename operation, i.e., it searches for similar content using the heuristics:

http://git-scm.com/docs/git-log

To lookup the full history, use the following command:

git log --follow ./path/to/file

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

try something like this

<script type="text/javascript">
function PopUp(hideOrshow) {
    if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
    else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
    setTimeout(function () {
        PopUp('show');
    }, 5000);
}
</script>

and your html

<div id="ac-wrapper" style='display:none'>
    <div id="popup">
        <center>
             <h2>Popup Content Here</h2>    
            <input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
        </center>
    </div>
</div>

Demo JsFiddle

This seems unnecessary, but VBA is a strange place. If you declare an array variable, then set it using Array() then pass the variable into your function, VBA will be happy.

Sub test()
    Dim fString As String
    Dim arr() As Variant
    arr = Array("foo", "bar")
    fString = processArr(arr)
End Sub

Also your function processArr() could be written as:

Function processArr(arr() As Variant) As String
    processArr = Replace(Join(arr()), " ", "")
End Function

If you are into the whole brevity thing.

Assuming that you are using UTF-8 encoding:

string convert = "This is the string to be converted";

// From string to byte array
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);

// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);

Yes! Use Powershell:

powershell -Command "Remove-Item 'c:\destination\*' -Recurse -Force"

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

<input type="text" required="true" value="" readonly>

Not the.

<input type="text" required="true" value="" readonly="true">

You could use IsEmpty() function like this:

...
Set rRng = Sheet1.Range("A10")
If IsEmpty(rRng.Value) Then ...

you could also use following:

If ActiveCell.Value = vbNullString Then ...

Have you tried using @JsonProperty?

@Entity
public class City {
   @id
   Long id;
   String name;

   @JsonProperty("label")
   public String getName() { return name; }

   public void setName(String name){ this.name = name; }

   @JsonProperty("value")
   public Long getId() { return id; }

   public void setId(Long id){ this.id = id; }
}

To remove everything before a specific char, use below.

string1 = string1.Substring(string1.IndexOf('$') + 1);

What this does is, takes everything before the $ char and removes it. Now if you want to remove the items after a character, just change the +1 to a -1 and you are set!

But for a URL, I would use the built in .NET class to take of that.

Here's what worked for me.

Html using the directive

 <tr orderitemdirective remove="vm.removeOrderItem(orderItem)" order-item="orderitem"></tr>

Html of the directive: orderitem.directive.html

<md-button type="submit" ng-click="remove({orderItem:orderItem})">
       (...)
</md-button>

Directive's scope:

scope: {
    orderItem: '=',
    remove: "&",

Here's another use case, if you would like to copy the current url to your clipboard:

Define a method

const copyToClipboard = e => {
  navigator.clipboard.writeText(window.location.toString())
}

Call that method

<button copyToClipboard={shareLink}>
   Click to copy current url to clipboard
</button>

The "Issue 2" answer given by @Sagar works for the majority of git servers such as gitorious.

However, there will be a name clash in a system like gitolite where the public ssh keys are checked in as files named with the username, ie keydir/jenkins.pub. What if there are multiple jenkins servers that need to access the same gitolite server?

(Note: this is about running the Jenkins daemon not running a build job as a user (addressed by @Sagar's "Issue 1").)

So in this case you do need to run the Jenkins daemon as a different user.

There are two steps:

Step 1

The main thing is to update the JENKINS_USER environment variable. Here's a patch showing how to change the user to ptran.

    $scope.users = data.users;
}).error(function (data, status, headers, config) {
    $scope.status = status + ' ' + headers;
});

You can return more than one value using list also. Check the code below

def newFn():    #your function
  result = []    #defining blank list which is to be return
  r1 = 'return1'    #first value
  r2 = 'return2'    #second value
  result.append(r1)    #adding first value in list
  result.append(r2)    #adding second value in list
  return result    #returning your list

ret_val1 = newFn()[1]    #you can get any desired result from it
print ret_val1    #print/manipulate your your result

In swift 3:

var a: Double = 1.5
var b: String = String(a)

UPDATE

Adding the CSS property elevation: 1 renders shadow in Android without installing any 3rd party library — see the other answers.

One way to get shadows for android is to install react-native-shadow.

Example (adapted from the readme):

import React, { Component } from "react";
import { TouchableHighlight } from "react-native";

import { BoxShadow } from "react-native-shadow";

export default class ShadowButton extends Component {
  render() {
    const shadowOpt = {
      width: 160,
      height: 170,
      color: "#000",
      border: 2,
      radius: 3,
      opacity: 0.2,
      x: 0,
      y: 3,
      style: { marginVertical: 5 }
    };

    return (
      <BoxShadow setting={shadowOpt}>
        <TouchableHighlight
          style={{
            position: "relative",
            width: 160,
            height: 170,
            backgroundColor: "#fff",
            borderRadius: 3,
            // marginVertical: 5,
            overflow: "hidden"
          }}
        >
          ...
        </TouchableHighlight>
      </BoxShadow>
    );
  }
}

This is what I am using:

Milliseconds to a pretty format time string:

function ms2Time(ms) {
    var secs = ms / 1000;
    ms = Math.floor(ms % 1000);
    var minutes = secs / 60;
    secs = Math.floor(secs % 60);
    var hours = minutes / 60;
    minutes = Math.floor(minutes % 60);
    hours = Math.floor(hours % 24);
    return hours + ":" + minutes + ":" + secs + "." + ms;

First of all, as @AndrewFinnell and @KenLiu point out, in SVN the directory names themselves mean nothing -- "trunk, branches and tags" are simply a common convention that is used by most repositories. Not all projects use all of the directories (it's reasonably common not to use "tags" at all), and in fact, nothing is stopping you from calling them anything you'd like, though breaking convention is often confusing.

I'll describe probably the most common usage scenario of branches and tags, and give an example scenario of how they are used.

• Trunk: The main development area. This is where your next major release of the code lives, and generally has all the newest features.

• Branches: Every time you release a major version, it gets a branch created. This allows you to do bug fixes and make a new release without having to release the newest - possibly unfinished or untested - features.

• Tags: Every time you release a version (final release, release candidates (RC), and betas) you make a tag for it. This gives you a point-in-time copy of the code as it was at that state, allowing you to go back and reproduce any bugs if necessary in a past version, or re-release a past version exactly as it was. Branches and tags in SVN are lightweight - on the server, it does not make a full copy of the files, just a marker saying "these files were copied at this revision" that only takes up a few bytes. With this in mind, you should never be concerned about creating a tag for any released code. As I said earlier, tags are often omitted and instead, a changelog or other document clarifies the revision number when a release is made.

For example, let's say you start a new project. You start working in "trunk", on what will eventually be released as version 1.0.

• trunk/ - development version, soon to be 1.0
• branches/ - empty

Once 1.0.0 is finished, you branch trunk into a new "1.0" branch, and create a "1.0.0" tag. Now work on what will eventually be 1.1 continues in trunk.

• trunk/ - development version, soon to be 1.1
• branches/1.0 - 1.0.0 release version
• tags/1.0.0 - 1.0.0 release version

You come across some bugs in the code, and fix them in trunk, and then merge the fixes over to the 1.0 branch. You can also do the opposite, and fix the bugs in the 1.0 branch and then merge them back to trunk, but commonly projects stick with merging one-way only to lessen the chance of missing something. Sometimes a bug can only be fixed in 1.0 because it is obsolete in 1.1. It doesn't really matter: you only want to make sure that you don't release 1.1 with the same bugs that have been fixed in 1.0.

• trunk/ - development version, soon to be 1.1
• branches/1.0 - upcoming 1.0.1 release
• tags/1.0.0 - 1.0.0 release version

Once you find enough bugs (or maybe one critical bug), you decide to do a 1.0.1 release. So you make a tag "1.0.1" from the 1.0 branch, and release the code. At this point, trunk will contain what will be 1.1, and the "1.0" branch contains 1.0.1 code. The next time you release an update to 1.0, it would be 1.0.2.

• trunk/ - development version, soon to be 1.1
• branches/1.0 - upcoming 1.0.2 release
• tags/1.0.0 - 1.0.0 release version
• tags/1.0.1 - 1.0.1 release version

Eventually you are almost ready to release 1.1, but you want to do a beta first. In this case, you likely do a "1.1" branch, and a "1.1beta1" tag. Now, work on what will be 1.2 (or 2.0 maybe) continues in trunk, but work on 1.1 continues in the "1.1" branch.

• trunk/ - development version, soon to be 1.2
• branches/1.0 - upcoming 1.0.2 release
• branches/1.1 - upcoming 1.1.0 release
• tags/1.0.0 - 1.0.0 release version
• tags/1.0.1 - 1.0.1 release version
• tags/1.1beta1 - 1.1 beta 1 release version

Once you release 1.1 final, you do a "1.1" tag from the "1.1" branch.

You can also continue to maintain 1.0 if you'd like, porting bug fixes between all three branches (1.0, 1.1, and trunk). The important takeaway is that for every main version of the software you are maintaining, you have a branch that contains the latest version of code for that version.

Another use of branches is for features. This is where you branch trunk (or one of your release branches) and work on a new feature in isolation. Once the feature is completed, you merge it back in and remove the branch.

• trunk/ - development version, soon to be 1.2
• branches/1.1 - upcoming 1.1.0 release
• branches/ui-rewrite - experimental feature branch

The idea of this is when you're working on something disruptive (that would hold up or interfere with other people from doing their work), something experimental (that may not even make it in), or possibly just something that takes a long time (and you're afraid if it holding up a 1.2 release when you're ready to branch 1.2 from trunk), you can do it in isolation in branch. Generally you keep it up to date with trunk by merging changes into it all the time, which makes it easier to re-integrate (merge back to trunk) when you're finished.

Also note, the versioning scheme I used here is just one of many. Some teams would do bug fix/maintenance releases as 1.1, 1.2, etc., and major changes as 1.x, 2.x, etc. The usage here is the same, but you may name the branch "1" or "1.x" instead of "1.0" or "1.0.x". (Aside, semantic versioning is a good guide on how to do version numbers).

Tested with Angular 5.2.9

If you use an anchor instead of a button you must make it a passive link with href="javascript:void(0)" to make Angular Location work.

app.component.ts

import { Component } from '@angular/core';
import { Location } from '@angular/common';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent {

  constructor( private location: Location ) { 
  }

  goBack() {
    // window.history.back();
    this.location.back();

    console.log( 'goBack()...' );
  }
}

app.component.html

<!-- anchor must be a passive link -->
<a href="javascript:void(0)" (click)="goBack()">
  <-Back
</a>

No. = sets somevar to have that value. use === to compare value and type which returns a boolean that you need.

Never use or suggest == instead of ===. its a recipe for disaster. e.g 0 == "" is true but "" == '0' is false and many more.

I faced similar issue in Eclipse when two consoles were opened when I started the Server program first and then the Client program. I used to stop the program in the single console thinking that it had closed the server, but it had only closed the client and not the server. I found running Java processes in my Task manager. This problem was solved by closing both Server and Client programs from their individual consoles(Eclipse shows console of latest active program). So when I started the Server program again, the port was again open to be captured.

There is timeline.sty floating around.

The syntax is simpler than using tikz:

%%% In LaTeX:
%%% \begin{timeline}{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \end{timeline}
%%%
%%% in plain TeX
%%% \timeline{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \endtimeline
%%% in between the two, we may have:
%%% \item{date}{description}
%%% \item[sortkey]{date}{description}
%%% \optrule
%%%
%%% the options to timeline are:
%%%      length The amount of vertical space that the timeline should
%%%                use.
%%%      (start,stop) indicate the range of the timeline. All dates or
%%%                sortkeys should lie in the range [start,stop]
%%%
%%% \item without the sort key expects date to be a number (such as a
%%%      year).
%%% \item with the sort key expects the sort key to be a number; date
%%%      can be anything. This can be used for log scale time lines
%%%      or dates that include months or days.
%%% putting \optrule inside of the timeline environment will cause a
%%%      vertical rule to be drawn down the center of the timeline.

I've used python's datetime.data.toordinal to convert dates to 'sort keys' in the context of the package.

There's no need, just use fadeToggle() on the element:

$('#testElement').fadeToggle('fast');

Here's a demo.

For directories dirname gets tripped for ../ and returns ./.

nolan6000's function can be modified to fix that:

get_abs_filename() {
  # $1 : relative filename
  if [ -d "${1%/*}" ]; then
    echo "$(cd ${1%/*}; pwd)/${1##*/}"
  fi
}

Go into the mysql data directory and run du -h --max-depth=1 | grep databasename

You can use the following to change the background-color of a Jumbotron:

<div class="container">
    <div class="jumbotron text-white" style="background-color: #8c6278;">
        <h1>Coffee lover project !</h1>
    </div>
</div>

Two native solutions

• performance.now --> Call to ... took 6.414999981643632 milliseconds.
• console.time --> Call to ... took 5.815 milliseconds

The difference between both is precision.

For usage and explanation read on.

Performance.now (For microsecond precision use)

    var t0 = performance.now();
    doSomething();
    var t1 = performance.now();

    console.log("Call to doSomething took " + (t1 - t0) + " milliseconds.");
            
    function doSomething(){    
       for(i=0;i<1000000;i++){var x = i*i;}
    }

performance.now

Unlike other timing data available to JavaScript (for example Date.now), the timestamps returned by Performance.now() are not limited to one-millisecond resolution. Instead, they represent times as floating-point numbers with up to microsecond precision.

Also unlike Date.now(), the values returned by Performance.now() always increase at a constant rate, independent of the system clock (which might be adjusted manually or skewed by software like NTP). Otherwise, performance.timing.navigationStart + performance.now() will be approximately equal to Date.now().

console.time

Example: (timeEnd wrapped in setTimeout for simulation)

console.time('Search page');
  doSomething();
console.timeEnd('Search page');
 

 function doSomething(){    
       for(i=0;i<1000000;i++){var x = i*i;}
 }

You can change the Timer-Name for different operations.

Unless you have GNU awk 4.1.0 or later...

You won't have such an option as sed's -i option so instead do:

$ awk '{print $0}' file > tmp && mv tmp file

Note: the -i is not magic, it is also creating a temporary file sed just handles it for you.

As of GNU awk 4.1.0...

GNU awk added this functionality in version 4.1.0 (released 10/05/2013). It is not as straight forwards as just giving the -i option as described in the released notes:

The new -i option (from xgawk) is used for loading awk library files. This differs from -f in that the first non-option argument is treated as a script.

You need to use the bundled inplace.awk include file to invoke the extension properly like so:

$ cat file
123 abc
456 def
789 hij

$ gawk -i inplace '{print $1}' file

$ cat file
123
456
789

The variable INPLACE_SUFFIX can be used to specify the extension for a backup file:

$ gawk -i inplace -v INPLACE_SUFFIX=.bak '{print $1}' file

$ cat file
123
456
789

$ cat file.bak
123 abc
456 def
789 hij

I am happy this feature has been added but to me, the implementation isn't very awkish as the power comes from the conciseness of the language and -i inplace is 8 characters too long i.m.o.

Here is a link to the manual for the official word.

Try to use createChild() method of DOM or insertRow() and insertCell() method of table object in script tag.

Use immutableJS

import { fromJS } from 'immutable';

// An object we want to clone
let objA = { 
   a: { deep: 'value1', moreDeep: {key: 'value2'} } 
};

let immB = fromJS(objA); // Create immutable Map
let objB = immB.toJS(); // Convert to plain JS object

console.log(objA); // Object { a: { deep: 'value1', moreDeep: {key: 'value2'} } }
console.log(objB); // Object { a: { deep: 'value1', moreDeep: {key: 'value2'} } }

// objA and objB are equalent, but now they and their inner objects are undependent
console.log(objA === objB); // false
console.log(objA.a === objB.a); // false
console.log(objA.moreDeep === objB.moreDeep); // false

Or lodash/merge

import merge from 'lodash/merge'

var objA = {
    a: [{ 'b': 2 }, { 'd': 4 }]
};
// New deeply cloned object:
merge({}, objA ); 

// We can also create new object from several objects by deep merge:
var objB = {
    a: [{ 'c': 3 }, { 'e': 5 }]
};
merge({}, objA , objB ); // Object { a: [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }

The question is what do you want the div's height/width to be a percent of?

By default, if you assign a percentage value to a height/width it will be relative to it's direct parent dimensions. If the parent doesn't have a defined height, then it won't work.

So simply, remember to set the height of the parent, then a percentage height will work via the css attribute:

obj.style.width = '50%';

Both choices refer to what algorithm the identity provider uses to sign the JWT. Signing is a cryptographic operation that generates a "signature" (part of the JWT) that the recipient of the token can validate to ensure that the token has not been tampered with.

• RS256 (RSA Signature with SHA-256) is an asymmetric algorithm, and it uses a public/private key pair: the identity provider has a private (secret) key used to generate the signature, and the consumer of the JWT gets a public key to validate the signature. Since the public key, as opposed to the private key, doesn't need to be kept secured, most identity providers make it easily available for consumers to obtain and use (usually through a metadata URL).

• HS256 (HMAC with SHA-256), on the other hand, involves a combination of a hashing function and one (secret) key that is shared between the two parties used to generate the hash that will serve as the signature. Since the same key is used both to generate the signature and to validate it, care must be taken to ensure that the key is not compromised.

If you will be developing the application consuming the JWTs, you can safely use HS256, because you will have control on who uses the secret keys. If, on the other hand, you don't have control over the client, or you have no way of securing a secret key, RS256 will be a better fit, since the consumer only needs to know the public (shared) key.

Since the public key is usually made available from metadata endpoints, clients can be programmed to retrieve the public key automatically. If this is the case (as it is with the .Net Core libraries), you will have less work to do on configuration (the libraries will fetch the public key from the server). Symmetric keys, on the other hand, need to be exchanged out of band (ensuring a secure communication channel), and manually updated if there is a signing key rollover.

Auth0 provides metadata endpoints for the OIDC, SAML and WS-Fed protocols, where the public keys can be retrieved. You can see those endpoints under the "Advanced Settings" of a client.

The OIDC metadata endpoint, for example, takes the form of https://{account domain}/.well-known/openid-configuration. If you browse to that URL, you will see a JSON object with a reference to https://{account domain}/.well-known/jwks.json, which contains the public key (or keys) of the account.

If you look at the RS256 samples, you will see that you don't need to configure the public key anywhere: it's retrieved automatically by the framework.

Use PowerManager.WakeLock class inorder to perform this. See the following code:

import android.os.PowerManager;

public class MyActivity extends Activity {

    protected PowerManager.WakeLock mWakeLock;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(final Bundle icicle) {
        setContentView(R.layout.main);

        /* This code together with the one in onDestroy() 
         * will make the screen be always on until this Activity gets destroyed. */
        final PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
        this.mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
        this.mWakeLock.acquire();
    }

    @Override
    public void onDestroy() {
        this.mWakeLock.release();
        super.onDestroy();
    }
}

Use the follwing permission in manifest file :

<uses-permission android:name="android.permission.WAKE_LOCK" />

Hope this will solve your problem...:)

It turns out you can also use pow(). For example, you can use the following to express 10 to the 9th.

pow(10, 9)

Along with pow, powf() returns a float instead of a double. I have only tested this on Swift 4 and macOS 10.13.

Note for Windows users, the jars should be separated by ; and not :.

for example: javac -cp external_libs\lib1.jar;other\lib2.jar;

You have to first clear the table and then add new data using row.add() function. At last step adjust also column size so that table renders correctly.

$('#upload-new-data').on('click', function () {
   datatable.clear().draw();
   datatable.rows.add(NewlyCreatedData); // Add new data
   datatable.columns.adjust().draw(); // Redraw the DataTable
});

Also if you want to find a mapping between old and new datatable API functions bookmark this

May not be the exact one-liner you were hoping for but you could have a look at http://github.com/nodejitsu/node-http-proxy as that may shed some light on how you can use your app with http.Client.

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName
Set
Created="01/01/2000"
where Created is NULL

First backup the database. Then drop any foreign key associated with the table. truncate the foreign key table.Truncate the current table. Remove the required primary keys. Use sqlyog or workbench or heidisql or dbeaver or phpmyadmin.

I had the same problem and error, I tried changing the ports for http port from 80 to 81 and ssl port from 443 to 444 but still received the same error so I reverted the ports to default and ran setup_xampp.bat which solve the problem in seconds.

I attended a coursera course, there was lesson in which, we were taught about design recipe.

Below docstring format I found preety useful.

def area(base, height):
    '''(number, number ) -> number    #**TypeContract**
    Return the area of a tring with dimensions base   #**Description**
    and height

    >>>area(10,5)          #**Example **
    25.0
    >>area(2.5,3)
    3.75
    '''
    return (base * height) /2 

I think if docstrings are written in this way, it might help a lot to developers.

Sign-off is a line at the end of the commit message which certifies who is the author of the commit. Its main purpose is to improve tracking of who did what, especially with patches.

Example commit:

Add tests for the payment processor.

Signed-off-by: Humpty Dumpty <[email protected]>

It should contain the user real name if used for an open-source project.

If branch maintainer need to slightly modify patches in order to merge them, he could ask the submitter to rediff, but it would be counter-productive. He can adjust the code and put his sign-off at the end so the original author still gets credit for the patch.

As mentioned in some of the comments, ReactDOM.render no longer returns the component instance. You can pass a ref callback in when rendering the root of the component to get the instance, like so:

// React code (jsx)
function MyWidget(el, refCb) {
    ReactDOM.render(<MyComponent ref={refCb} />, el);
}
export default MyWidget;

and:

// vanilla javascript code
var global_widget_instance;

MyApp.MyWidget(document.getElementById('my_container'), function(widget) {
    global_widget_instance = widget;
});

global_widget_instance.myCoolMethod();

You can disconnect everyone and roll back their transactions with:

alter database [MyDatbase] set single_user with rollback immediate

After that, you can safely drop the database :)

Using all the examples below to get this code:

            Console.ReadLine();
        }
    }
}

I get these results on an AMD Ahtlon 64 X2 Dual Core 4200+ (2.2 GHz):

Test 1 = 2352048 ticks
Test 2 = 614550 ticks
Test 3 = 1354784 ticks
Test 4 = 844519 ticks
Test 5 = 150021 ticks
Test 6 = 192303 ticks

But get these on a AMD FX 8350 Eight Core (4.00 GHz)

Test 1 = 3917354 ticks
Test 2 = 811727 ticks
Test 3 = 2187388 ticks
Test 4 = 1790292 ticks
Test 5 = 241150 ticks
Test 6 = 227738 ticks

So whether or not method 5 or 6 is faster depends on the CPU, I can only surmise this is because the branch prediction in the command processor of the CPU is smarter on the new processor, but I'm not really sure.

I dont have any Intel CPUs, maybe someone could test it for us?

In case that you're using a directive like me this is how it works when you need the two data way binding for example after updating an attribute in any model or collection:

angular.module('yourApp').directive('setSurveyInEditionMode', setSurveyInEditionMode)

function setSurveyInEditionMode() {
  return {
    restrict: 'A',
    link: function(scope, element, $attributes) {
      element.on('click', function(event){
        event.stopPropagation();
        // In order to work with stopPropagation and two data way binding
        // if you don't use scope.$apply in my case the model is not updated in the view when I click on the element that has my directive
        scope.$apply(function () {
          scope.mySurvey.inEditionMode = true;
          console.log('inside the directive')
        });
      });
    }
  }
}

Now, you can easily use it in any button, link, div, etc. like so:

<button set-survey-in-edition-mode >Edit survey</button>

Another way is to select a column with the columns array:

In [5]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])

In [6]: df
Out[6]: 
   a  b
0  1  2
1  3  4

In [7]: df[df.columns[0]]
Out[7]: 
0    1
1    3
Name: a, dtype: int64

If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/

It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates

Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/

There are some SPARQL libraries available for multiple platforms to make queries easier

Here is a solution I found, if you look at the source of the page you can see how they implement their examples as well:

If you don't want that every time you open a terminal, do the suggestion above again, just add

source ~/.rvm/scripts/rvm

at the end of ~/.bashrc

Ted's answer is amazing. I ended up using a smaller version of that in case anyone is interested. Useful when you are looking for one aggregation that depends on values from multiple columns:

create a dataframe

df=pd.DataFrame({'a': [1,2,3,4,5,6], 'b': [1,1,0,1,1,0], 'c': ['x','x','y','y','z','z']})


   a  b  c
0  1  1  x
1  2  1  x
2  3  0  y
3  4  1  y
4  5  1  z
5  6  0  z

grouping and aggregating with apply (using multiple columns)

df.groupby('c').apply(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())

c
x    2.0
y    4.0
z    5.0

grouping and aggregating with aggregate (using multiple columns)

I like this approach since I can still use aggregate. Perhaps people will let me know why apply is needed for getting at multiple columns when doing aggregations on groups.

It seems obvious now, but as long as you don't select the column of interest directly after the groupby, you will have access to all the columns of the dataframe from within your aggregation function.

only access to the selected column

df.groupby('c')['a'].aggregate(lambda x: x[x>1].mean())

access to all columns since selection is after all the magic

df.groupby('c').aggregate(lambda x: x[(x['a']>1) & (x['b']==1)].mean())['a']

or similarly

df.groupby('c').aggregate(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())

I hope this helps.

If you are using php5-fpm do remeber to restart it, after installing mcrypt

service php5-fpm restart

If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:

curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Doing this you'll force to use es without replicas

Solution:

1. Start emulator (separately) and wait until it is fully loaded.
2. Open keylock.
3. Navigate to Eclipse and run your app.

Cause of the problem: Android emulator hasn't loaded all its libraries which handle the installing of a new application and due to that you run into java.io.IOException: EOF

That was causing me the problem.

Remember that CURRENT_TIMESTAMP - (number) works fine, but that you need to understand what number it is looking for - it is floating-point number of days. So CURRENT_TIMESTAMP-1.0 is 1 day ago, CURRENT_TIMESTAMP-0.5 is 1/2 day ago. For 30 minutes, that is 1.0/48.0 (use radix so result is a floating point number) or 0.0208333333333333, so your query will work if re-written as

select * from
[Janus999DB].[dbo].[tblCustomerPlay]
where DatePlayed < CURRENT_TIMESTAMP
and DatePlayed >
CURRENT_TIMESTAMP-1.0/48.0

You could also use 1.0/24.0/2.0 if that looks more like 1/2 hour to you.

Just use ng-show and a boolean

No need to use a directive, no need to get complicated.

Here is the code to put next to submit button or wherever you want the spinner to be:

<span ng-show="dataIsLoading">
  <img src="http://www.nasa.gov/multimedia/videogallery/ajax-loader.gif" style="height:20px;"/>
</span>

And then in your controller:

$scope.dataIsLoading = true

let url = '/whatever_Your_URL_Is'
$http.get(url)
.then(function(response) {
  $scope.dataIsLoading = false
})

The input operator for number skips leading whitespace, so you can just read the number in a loop:

while (myfile >> a)
{
    // ...
}

All you need to do is run

pip install /opt/mypackage

and pip will search /opt/mypackage for a setup.py, build a wheel, then install it.

The problem with using the -e flag for pip install as suggested in the comments and this answer is that this requires that the original source directory stay in place for as long as you want to use the module. It's great if you're a developer working on the source, but if you're just trying to install a package, it's the wrong choice.

Alternatively, you don't even need to download the repo from Github at all. pip supports installing directly from git repos using a variety of protocols including HTTP, HTTPS, and SSH, among others. See the docs I linked to for examples.

I do realize that my answer is way late for this question but I think the community would like a newer approach to this issue.

Noting down my situation here may be useful to somebody,

I have to send a custom intent with multiple intent extras to a broadcast receiver in Android P,

The details are,

Receiver name: com.hardian.testservice.TestBroadcastReceiver

Intent action = "com.hardian.testservice.ADD_DATA"

intent extras are,

1. "text"="test msg",
2. "source"= 1,

Run the following in command line.

adb shell "am broadcast -a com.hardian.testservice.ADD_DATA --es text 'test msg' --es source 1 -n com.hardian.testservice/.TestBroadcastReceiver"

Hope this helps.

1. Kernel Mode

   In Kernel mode, the executing code has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system. Crashes in kernel mode are catastrophic; they will halt the entire PC.

2. User Mode

   In User mode, the executing code has no ability to directly access hardware or reference memory. Code running in user mode must delegate to system APIs to access hardware or memory. Due to the protection afforded by this sort of isolation, crashes in user mode are always recoverable. Most of the code running on your computer will execute in user mode.

A task is something you want done.

A thread is one of the many possible workers which performs that task.

In .NET 4.0 terms, a Task represents an asynchronous operation. Thread(s) are used to complete that operation by breaking the work up into chunks and assigning to separate threads.

<script language="javascript" type="text/javascript">
        function fixedlength(textboxID, keyEvent, maxlength) {
            //validation for digits upto 'maxlength' defined by caller function
            if (textboxID.value.length > maxlength) {
                textboxID.value = textboxID.value.substr(0, maxlength);
            }
            else if (textboxID.value.length < maxlength || textboxID.value.length == maxlength) {
                textboxID.value = textboxID.value.replace(/[^\d]+/g, '');
                return true;
            }
            else
                return false;
        }
 </script>

<asp:TextBox ID="txtNextVisit" runat="server" MaxLength="2" onblur="return fixedlength(this, event, 2);" onkeypress="return fixedlength(this, event, 2);" onkeyup="return fixedlength(this, event, 2);"></asp:TextBox> 

Executing programs through the shell means that all user input passed to the program is interpreted according to the syntax and semantic rules of the invoked shell. At best, this only causes inconvenience to the user, because the user has to obey these rules. For instance, paths containing special shell characters like quotation marks or blanks must be escaped. At worst, it causes security leaks, because the user can execute arbitrary programs.

shell=True is sometimes convenient to make use of specific shell features like word splitting or parameter expansion. However, if such a feature is required, make use of other modules are given to you (e.g. os.path.expandvars() for parameter expansion or shlex for word splitting). This means more work, but avoids other problems.

In short: Avoid shell=True by all means.

This answer describes a solution using MVVM.

This solution is great if you want to add a logging box to a window, that automatically scrolls to the bottom each time a new logging message is added.

Once these attached properties are added, they can be reused anywhere, so it makes for very modular and reusable software.

Add this XAML:

<TextBox IsReadOnly="True"   
         Foreground="Gainsboro"                           
         FontSize="13" 
         ScrollViewer.HorizontalScrollBarVisibility="Auto"
         ScrollViewer.VerticalScrollBarVisibility="Auto"
         ScrollViewer.CanContentScroll="True"
         attachedBehaviors:TextBoxApppendBehaviors.AppendText="{Binding LogBoxViewModel.AttachedPropertyAppend}"                                       
         attachedBehaviors:TextBoxClearBehavior.TextBoxClear="{Binding LogBoxViewModel.AttachedPropertyClear}"                                    
         TextWrapping="Wrap">

Add this attached property:

public static class TextBoxApppendBehaviors
{
    #region AppendText Attached Property
    public static readonly DependencyProperty AppendTextProperty =
        DependencyProperty.RegisterAttached(
            "AppendText",
            typeof (string),
            typeof (TextBoxApppendBehaviors),
            new UIPropertyMetadata(null, OnAppendTextChanged));

    public static string GetAppendText(TextBox textBox)
    {
        return (string)textBox.GetValue(AppendTextProperty);
    }

    public static void SetAppendText(
        TextBox textBox,
        string value)
    {
        textBox.SetValue(AppendTextProperty, value);
    }

    private static void OnAppendTextChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs args)
    {
        if (args.NewValue == null)
        {
            return;
        }

        string toAppend = args.NewValue.ToString();

        if (toAppend == "")
        {
            return;
        }

        TextBox textBox = d as TextBox;
        textBox?.AppendText(toAppend);
        textBox?.ScrollToEnd();
    }
    #endregion
}

And this attached property (to clear the box):

public static class TextBoxClearBehavior
{
    public static readonly DependencyProperty TextBoxClearProperty =
        DependencyProperty.RegisterAttached(
            "TextBoxClear",
            typeof(bool),
            typeof(TextBoxClearBehavior),
            new UIPropertyMetadata(false, OnTextBoxClearPropertyChanged));

    public static bool GetTextBoxClear(DependencyObject obj)
    {
        return (bool)obj.GetValue(TextBoxClearProperty);
    }

    public static void SetTextBoxClear(DependencyObject obj, bool value)
    {
        obj.SetValue(TextBoxClearProperty, value);
    }

    private static void OnTextBoxClearPropertyChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs args)
    {
        if ((bool)args.NewValue == false)
        {
            return;
        }

        var textBox = (TextBox)d;
        textBox?.Clear();
    }
}   

Then, if you're using a dependency injection framework such as MEF, you can place all of the logging-specific code into it's own ViewModel:

public interface ILogBoxViewModel
{
    void CmdAppend(string toAppend);
    void CmdClear();

    bool AttachedPropertyClear { get; set; }

    string AttachedPropertyAppend { get; set; }
}

[Export(typeof(ILogBoxViewModel))]
public class LogBoxViewModel : ILogBoxViewModel, INotifyPropertyChanged
{
    private readonly ILog _log = LogManager.GetLogger<LogBoxViewModel>();

    private bool _attachedPropertyClear;
    private string _attachedPropertyAppend;

    public void CmdAppend(string toAppend)
    {
        string toLog = $"{DateTime.Now:HH:mm:ss} - {toAppend}\n";

        // Attached properties only fire on a change. This means it will still work if we publish the same message twice.
        AttachedPropertyAppend = "";
        AttachedPropertyAppend = toLog;

        _log.Info($"Appended to log box: {toAppend}.");
    }

    public void CmdClear()
    {
        AttachedPropertyClear = false;
        AttachedPropertyClear = true;

        _log.Info($"Cleared the GUI log box.");
    }

    public bool AttachedPropertyClear
    {
        get { return _attachedPropertyClear; }
        set { _attachedPropertyClear = value; OnPropertyChanged(); }
    }

    public string AttachedPropertyAppend
    {
        get { return _attachedPropertyAppend; }
        set { _attachedPropertyAppend = value; OnPropertyChanged(); }
    }

    #region INotifyPropertyChanged
    public event PropertyChangedEventHandler PropertyChanged;

    [NotifyPropertyChangedInvocator]
    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
    #endregion
}

Here's how it works:

• The ViewModel toggles the Attached Properties to control the TextBox.
• As it's using "Append", it's lightning fast.
• Any other ViewModel can generate logging messages by calling methods on the logging ViewModel.
• As we use the ScrollViewer built into the TextBox, we can make it automatically scroll to the bottom of the textbox each time a new message is added.

If you are not using programming then do the following (1) select the column (2) right click and select Format Cells (3) Select "Custom" (4) Just Under "Type:" type dd/mm/yyyy hh:mm:ss

Number only regex (Updated)

 var reg = new RegExp('[^0-9]','g');

this style can be used in makefiles too (and in fact it is used quite often).

python - <<EOF
import sys
for r in range(3): print 'rob'
EOF

or

python - <<-EOF
    import sys
    for r in range(3): print 'rob'
EOF

in latter case leading tab characters are removed too (and some structured outlook can be achieved)

instead of EOF can stand any marker word not appearing in the here document at a beginning of a line (see also here documents in the bash manpage or here).

This is from the official website. php.net

After installation of PHP.

Windows

Move to Windows\system32 folder: libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll

All of my applications have quit buttons... and I quite frequently get positive comments from users because of it. I don't care if the platform was designed in a fashion that applications shouldn't need them. Saying "don't put them there" is kind of ridiculous. If the user wants to quit... I provide them the access to do exactly that. I don't think it reduces how Android operates at all and seems like a good practice. I understand the life cycle... and my observation has been that Android doesn't do a good job at handling it.... and that is a basic fact.

From here what I understand DataFrames are:

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dict of Series objects.

And Series are:

Series is a one-dimensional labeled array capable of holding any data type (integers, strings, floating point numbers, Python objects, etc.).

Series have a name attribute which can be accessed like so:

 In [27]: s = pd.Series(np.random.randn(5), name='something')

 In [28]: s
 Out[28]: 
 0    0.541
 1   -1.175
 2    0.129
 3    0.043
 4   -0.429
 Name: something, dtype: float64

 In [29]: s.name
 Out[29]: 'something'

EDIT: Based on OP's comments, I think OP was looking for something like:

 >>> df = pd.DataFrame(...)
 >>> df.name = 'df' # making a custom attribute that DataFrame doesn't intrinsically have
 >>> print(df.name)
 'df'

Another way you can achieve the desired effect is to use this Material Search View library. It handles search history automatically and it's possible to provide search suggestions to the view as well.

Sample: (It's shown in Portuguese, but it also works in english and italian).

Setup

Before you can use this lib, you have to implement a class named MsvAuthority inside the br.com.mauker package on your app module, and it should have a public static String variable called CONTENT_AUTHORITY. Give it the value you want and don't forget to add the same name on your manifest file. The lib will use this file to set the Content Provider authority.

Example:

MsvAuthority.java

package br.com.mauker;

public class MsvAuthority {
    public static final String CONTENT_AUTHORITY = "br.com.mauker.materialsearchview.searchhistorydatabase";
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>

    <application ... >
        <provider
        android:name="br.com.mauker.materialsearchview.db.HistoryProvider"
        android:authorities="br.com.mauker.materialsearchview.searchhistorydatabase"
        android:exported="false"
        android:protectionLevel="signature"
        android:syncable="true"/>
    </application>

</manifest>

Usage

To use it, add the dependency:

compile 'br.com.mauker.materialsearchview:materialsearchview:1.2.0'

And then, on your Activity layout file, add the following:

<br.com.mauker.materialsearchview.MaterialSearchView
    android:id="@+id/search_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

After that, you'll just need to get the MaterialSearchView reference by using getViewById(), and open it up or close it using MaterialSearchView#openSearch() and MaterialSearchView#closeSearch().

P.S.: It's possible to open and close the view not only from the Toolbar. You can use the openSearch() method from basically any Button, such as a Floating Action Button.

// Inside onCreate()
MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
Button bt = (Button) findViewById(R.id.button);

bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            searchView.openSearch();
        }
    });

You can also close the view using the back button, doing the following:

@Override
public void onBackPressed() {
    if (searchView.isOpen()) {
        // Close the search on the back button press.
        searchView.closeSearch();
    } else {
        super.onBackPressed();
    }
}

For more information on how to use the lib, check the github page.

If you have a numeric column that you want to auto-increment, it might be an option to set columnDefinition directly. This has the advantage, that the schema auto-generates the value even if it is used without hibernate. This might make your code db-specific though:

import javax.persistence.Column;
@Column(columnDefinition = "serial") // postgresql

Yes, it's a standard practice to commit package-lock.json.

The main reason for committing package-lock.json is that everyone in the project is on the same package version.

Pros:

• If you follow strict versioning and don't allow updating to major versions automatically to save yourself from backward-incompatible changes in third-party packages committing package-lock helps a lot.
• If you update a particular package, it gets updated in package-lock.json and everyone using the repository gets updated to that particular version when they take the pull of your changes.

Cons:

• It can make your pull requests look ugly :)

npm install won't make sure that everyone in the project is on the same package version. npm ci will help with this.

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.colors import ListedColormap

#discrete color scheme
cMap = ListedColormap(['white', 'green', 'blue','red'])

#data
np.random.seed(42)
data = np.random.rand(4, 4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data, cmap=cMap)

#legend
cbar = plt.colorbar(heatmap)

cbar.ax.get_yaxis().set_ticks([])
for j, lab in enumerate(['$0$','$1$','$2$','$>3$']):
    cbar.ax.text(.5, (2 * j + 1) / 8.0, lab, ha='center', va='center')
cbar.ax.get_yaxis().labelpad = 15
cbar.ax.set_ylabel('# of contacts', rotation=270)


# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[1]) + 0.5, minor=False)
ax.set_yticks(np.arange(data.shape[0]) + 0.5, minor=False)
ax.invert_yaxis()

#labels
column_labels = list('ABCD')
row_labels = list('WXYZ')
ax.set_xticklabels(column_labels, minor=False)
ax.set_yticklabels(row_labels, minor=False)

plt.show()

You were very close. Once you have a reference to the color bar axis, you can do what ever you want to it, including putting text labels in the middle. You might want to play with the formatting to make it more visible.

One more way is::

Write a method in your adapter lets say public void callBack(){}.

Now while creating an object for adapter in activity override this method. Override method will be called when you call the method in adapter.

Myadapter adapter = new Myadapter() {
  @Override
  public void callBack() {
    // dosomething
  }
};

Every Ansible task when run can save its results into a variable. To do this, you have to specify which variable to save the results into. Do this with the register parameter, independently of the module used.

Once you save the results to a variable you can use it later in any of the subsequent tasks. So for example if you want to get the standard output of a specific task you can write the following:

---
- hosts: localhost
  tasks:
    - shell: ls
      register: shell_result

    - debug:
        var: shell_result.stdout_lines

Here register tells ansible to save the response of the module into the shell_result variable, and then we use the debug module to print the variable out.

An example run would look like the this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
changed: [localhost]

TASK [debug] *******************************************************************
ok: [localhost] => {
    "shell_result.stdout_lines": [
        "play.yml"
    ]
}

Responses can contain multiple fields. stdout_lines is one of the default fields you can expect from a module's response.

Not all fields are available from all modules, for example for a module which doesn't return anything to the standard out you wouldn't expect anything in the stdout or stdout_lines values, however the msg field might be filled in this case. Also there are some modules where you might find something in a non-standard variable, for these you can try to consult the module's documentation for these non-standard return values.

Alternatively you can increase the verbosity level of ansible-playbook. You can choose between different verbosity levels: -v, -vvv and -vvvv. For example when running the playbook with verbosity (-vvv) you get this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
(...)
changed: [localhost] => {
    "changed": true,
    "cmd": "ls",
    "delta": "0:00:00.007621",
    "end": "2017-02-17 23:04:41.912570",
    "invocation": {
        "module_args": {
            "_raw_params": "ls",
            "_uses_shell": true,
            "chdir": null,
            "creates": null,
            "executable": null,
            "removes": null,
            "warn": true
        },
        "module_name": "command"
    },
    "rc": 0,
    "start": "2017-02-17 23:04:41.904949",
    "stderr": "",
    "stdout": "play.retry\nplay.yml",
    "stdout_lines": [
        "play.retry",
        "play.yml"
    ],
    "warnings": []
}

As you can see this will print out the response of each of the modules, and all of the fields available. You can see that the stdout_lines is available, and its contents are what we expect.

To answer your main question about the jenkins_script module, if you check its documentation, you can see that it returns the output in the output field, so you might want to try the following:

tasks:
  - jenkins_script:
      script: (...)
    register: jenkins_result

  - debug:
      var: jenkins_result.output

Biginteger is an immutable class. You need to explicitly assign value of your output to sum like this:

sum = sum.add(BigInteger.valueof(i));    

In my case I needed to pass arguments to a targetFragment. But I got exception "Fragment already active". So I declared an Interface in my DialogFragment which parentFragment implemented. When parentFragment started a DialogFragment , it set itself as TargetFragment. Then in DialogFragment I called

 ((Interface)getTargetFragment()).onSomething(selectedListPosition);

Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:

str = str.replace(/[^-a-z0-9]+/g, "");

Also, if you need to match upper-case letters along with lower case, you should use:

str = str.replace(/[^-a-zA-Z0-9]+/g, "");

Please try this:

DELETE FROM `table` WHERE id >=163 and id<= 265

I have one my old function for that:

function putinplace($string=NULL, $put=NULL, $position=false)
{
    $d1=$d2=$i=false;
    $d=array(strlen($string), strlen($put));
    if($position > $d[0]) $position=$d[0];
    for($i=$d[0]; $i >= $position; $i--) $string[$i+$d[1]]=$string[$i];
    for($i=0; $i<$d[1]; $i++) $string[$position+$i]=$put[$i];
    return $string;
}

// Explanation
$string='My dog dont love postman'; // string
$put="'"; // put ' on position
$position=10; // number of characters (position)
print_r( putinplace($string, $put, $position) ); //RESULT: My dog don't love postman

This is a small powerful function that performs its job flawlessly.

If the file is coming off the disk and as others have stated, use the BaseName and Extension properties:

PS C:\> dir *.xlsx | select BaseName,Extension

BaseName                                Extension
--------                                ---------
StackOverflow.com Test Config           .xlsx  

If you are given the file name as part of string (say coming from a text file), I would use the GetFileNameWithoutExtension and GetExtension static methods from the System.IO.Path class:

PS C:\> [System.IO.Path]::GetFileNameWithoutExtension("Test Config.xlsx")
Test Config
PS H:\> [System.IO.Path]::GetExtension("Test Config.xlsx")
.xlsx

     public static void main(String[] args) {
    final String xmlStr = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n"+
                            "<Emp id=\"1\"><name>Pankaj</name><age>25</age>\n"+
                            "<role>Developer</role><gen>Male</gen></Emp>";
   DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  
        DocumentBuilder builder;  
        try 
        {  
            builder = factory.newDocumentBuilder();  
            Document doc = builder.parse( new InputSource( new StringReader( xmlStr )) ); 

        } catch (Exception e) {  
            e.printStackTrace();  
        } 
  }

let a =123456888
var str = String(a)

OR

var str = a as! String

Put the query arguments in hidden input fields:

<form action="http://spufalcons.com/index.aspx">
    <input type="hidden" name="tab" value="gymnastics" />
    <input type="hidden" name="path" value="gym" />
    <input type="submit" value="SPU Gymnastics"/>
</form>

You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all from the stringr package, though gsub from base R works just as well.

The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.

x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")

(The base R equivalent is gsub("[[:punct:]]", " ", x).)

An alternative is to swap out all non-alphanumeric characters.

str_replace_all(x, "[^[:alnum:]]", " ")

Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.

You want to use timeout. timeout 10 will sleep 10 seconds

You can try

member.substr(member.length-2);

You can use retus to make cross-platform synchronous HTTP requests:

const retus = require("retus");

const { body } = retus("https://google.com");
//=> "<!doctype html>..."

That's it!

The new way to do with c++20 is using format.

#include <format>

auto var = std::format("sometext {} sometext {}", somevar, somevar);
