Check out from dateutil.relativedelta import * for adding a specific amount of time to a date, you can continue to use timedelta for the simple stuff i.e.

use_date = use_date + datetime.timedelta(minutes=+10)
use_date = use_date + datetime.timedelta(hours=+1)
use_date = use_date + datetime.timedelta(days=+1)
use_date = use_date + datetime.timedelta(weeks=+1)

or you can start using relativedelta

use_date = use_date+relativedelta(months=+1)

use_date = use_date+relativedelta(years=+1)

for the last day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)

Right now this will provide 29/02/2016

for the penultimate day of next month:

use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
use_date = use_date+relativedelta(days=-1)

last Friday of the next month:

use_date = use_date+relativedelta(months=+1, day=31, weekday=FR(-1))

2nd Tuesday of next month:

new_date = use_date+relativedelta(months=+1, day=1, weekday=TU(2))

As @mrroot5 points out dateutil's rrule functions can be applied, giving you an extra bang for your buck, if you require date occurences.
for example:
Calculating the last day of the month for 9 months from the last day of last month.
Then, calculate the 2nd Tuesday for each of those months.

from dateutil.relativedelta import *
from dateutil.rrule import *
from datetime import datetime
use_date = datetime(2020,11,21)

#Calculate the last day of last month
use_date = use_date+relativedelta(months=-1)
use_date = use_date+relativedelta(day=31)

#Generate a list of the last day for 9 months from the calculated date
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, bymonthday=(-1,)))
print("Last day")
for ld in x:
    print(ld)

#Generate a list of the 2nd Tuesday in each of the next 9 months from the calculated date
print("\n2nd Tuesday")
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, byweekday=TU(2)))
for tuesday in x:
    print(tuesday)

Python 2.7

In python 2, the keys(), values(), and items() functions of OrderedDict return lists. Using values as an example, the simplest way is

d.values()[0]  # "python"
d.values()[1]  # "spam"

For large collections where you only care about a single index, you can avoid creating the full list using the generator versions, iterkeys, itervalues and iteritems:

import itertools
next(itertools.islice(d.itervalues(), 0, 1))  # "python"
next(itertools.islice(d.itervalues(), 1, 2))  # "spam"

The indexed.py package provides IndexedOrderedDict, which is designed for this use case and will be the fastest option.

from indexed import IndexedOrderedDict
d = IndexedOrderedDict({'foo':'python','bar':'spam'})
d.values()[0]  # "python"
d.values()[1]  # "spam"

Using itervalues can be considerably faster for large dictionaries with random access:

$ python2 -m timeit -s 'from collections import OrderedDict; from random import randint; size = 1000;   d = OrderedDict({i:i for i in range(size)})'  'i = randint(0, size-1); d.values()[i:i+1]'

Python 3.6

Python 3 has the same two basic options (list vs generator), but the dict methods return generators by default.

List method:

list(d.values())[0]  # "python"
list(d.values())[1]  # "spam"

Generator method:

import itertools
next(itertools.islice(d.values(), 0, 1))  # "python"
next(itertools.islice(d.values(), 1, 2))  # "spam"

Python 3 dictionaries are an order of magnitude faster than python 2 and have similar speedups for using generators.

When you first instantiate the $objPHPExcel, it already has a single sheet (sheet 0); you're then adding a new sheet (which will become sheet 1), but setting active sheet to sheet $i (when $i is 0)... so you're renaming and populating the original worksheet created when you instantiated $objPHPExcel rather than the one you've just added... this is your title "0".

You're also using the createSheet() method, which both creates a new worksheet and adds it to the workbook... but you're also adding it again yourself which is effectively adding the sheet in two position.

So first iteration, you already have sheet0, add a new sheet at both indexes 1 and 2, and edit/title sheet 0. Second iteration, you add a new sheet at both indexes 3 and 4, and edit/title sheet 1, but because you have the same sheet at indexes 1 and 2 this effectively writes to the sheet at index 2. Third iteration, you add a new sheet at indexes 5 and 6, and edit/title sheet 2, overwriting your earlier editing/titleing of sheet 1 which acted against sheet 2 instead.... and so on

Try phoneNumber.setVisibility(View.GONE);

How about this? (year 2015)

1) Get a custom marker image.

var imageObj = new Image();
    imageObj.src = "/markers/blank_pin.png"; 

2) Create a canvas in RAM and draw this image on it

imageObj.onload = function(){
    var canvas = document.createElement('canvas');
    var context = canvas.getContext("2d");
    context.drawImage(imageObj, 0, 0);
}

3) Write anything above it

context.font = "40px Arial";
context.fillText("54", 17, 55);

4) Get raw data from canvas and provide it to Google API instead of URL

var image = {
    url: canvas.toDataURL(),
 };
 new google.maps.Marker({
    position: position,
    map: map,
    icon: image
 });

Full code:

function addComplexMarker(map, position, label, callback){
    var canvas = document.createElement('canvas');
    var context = canvas.getContext("2d");
    var imageObj = new Image();
    imageObj.src = "/markers/blank_pin.png";
    imageObj.onload = function(){
        context.drawImage(imageObj, 0, 0);

        //Adjustable parameters
        context.font = "40px Arial";
        context.fillText(label, 17, 55);
        //End

        var image = {
            url: canvas.toDataURL(),
            size: new google.maps.Size(80, 104),
            origin: new google.maps.Point(0,0),
            anchor: new google.maps.Point(40, 104)
        };
        // the clickable region of the icon.
        var shape = {
            coords: [1, 1, 1, 104, 80, 104, 80 , 1],
            type: 'poly'
        };
        var marker = new google.maps.Marker({
            position: position,
            map: map,
            labelAnchor: new google.maps.Point(3, 30),
            icon: image,
            shape: shape,
            zIndex: 9999
        });
        callback && callback(marker)
    };
});

• HEAD~ specifies the first parent on a "branch"

• HEAD^ allows you to select a specific parent of the commit

An Example:

If you want to follow a side branch, you have to specify something like

master~209^2~15

The URL should point to your own custom filebrowser url you might have.

I have already done this in one of my projects, and I have posted a tutorial on this topic on my blog

http://www.mixedwaves.com/2010/02/integrating-fckeditor-filemanager-in-ckeditor/

The tutorial gives a step by step instructions about how to integrate the inbuilt FileBrowser of FCKEditor in CKEditor, if you don't want to make our own. Its pretty simple.

Use String#next as the counter.

>> n = "000"
>> 3.times { puts "file_#{n.next!}" }
file_001
file_002
file_003

next is relatively 'clever', meaning you can even go for

>> n = "file_000"
>> 3.times { puts n.next! }
file_001
file_002
file_003

Extension of VolkerK's answer, to make code a little more readable, you can use AS to reference the count, example below:

SELECT COUNT(*) AS c from profile

This makes for much easier reading in some frameworks, for example, i'm using Exponent's (React Native) Sqlite integration, and without the AS statement, the code is pretty ugly.

It turns out that lstlisting is able to format code nicely, but requires a lot of tweaking.

Wikibooks has a good example for the parameters you can tweak.

Remove method will causes a lot of shift of list elements. I think is better to make a copy:

...
new_list = []
for el in obj.my_list:
   if condition_is_true(el):
      new_list.append(el)
del obj.my_list
obj.my_list = new_list
...

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

if {le_gur_bond.gur1}="" or IsNull({le_gur_bond.gur1})   Then
    ""
else 
 "and " + {le_gur_bond.gur2} + " of "+ {le_gur_bond.grr_2_address2}

<div class="container">_x000D_
    <div class="row">_x000D_
        <div class="col d-flex justify-content-center">_x000D_
             CenterContent_x000D_
        </div>_x000D_
    </div>_x000D_
</div>

Enable 'flex' for the column as we want & use justify-content-center

Dockerfile is a file that contains text commands to assemble an image.

Docker compose is used to run a multi-container environment.

In your specific scenario, if you have multiple services for each technology you mentioned (service 1 using reddis, service 2 using rabbit mq etc), then you can have a Dockerfile for each of the services and a common docker-compose.yml to run all the "Dockerfile" as containers.

If you want them all in a single service, docker-compose will be a viable option.

I found this to be a lot easier

from dateutil import relativedelta
relativedelta.relativedelta(end_time,start_time).seconds

use box-shadow with no horizontal offset.

http://www.css3.info/preview/box-shadow/

eg.

div {_x000D_
  -webkit-box-shadow: 0 10px 5px #888888;_x000D_
  -moz-box-shadow: 0 10px 5px #888888;_x000D_
  box-shadow: 0 10px 5px #888888;_x000D_
}

<div>wefwefwef</div>

There will be a slight shadow on the sides with a large blur radius (5px in above example)

CSS
select{
  color:red;
 }

HTML
<select id="sel" onclick="document.getElementById('sel').style.color='green';">
 <option>Select Your Option</option>
 <option value="">INDIA</option>
 <option value="">USA</option>
</select>

The above code will change the colour of text on click of the select box.

and if you want every option different colour, give separate class or id to all options.

The point is semantics. In assertTrue, you are asserting that the expression is true. If it is not, then it will display the message and the assertion will fail. In assertFalse, you are asserting that an expression evaluates to false. If it is not, then the message is displayed and the assertion fails.

assertTrue (message, value == false) == assertFalse (message, value);

These are functionally the same, but if you are expecting a value to be false then use assertFalse. If you are expecting a value to be true, then use assertTrue.

I use ZF2 and work for me when replaced 'PHPUnit_Framework_TestCase' to '\PHPUnit\Framework\TestCase'

One command and does not use the destructive git reset command:

GIT_SEQUENCE_EDITOR="sed -i 's/pick/d/'" git rebase -i HEAD~ --autostash

It simply drops the commit, putting you back exactly in the state before the cherry-pick even if you had local changes.

Angular 1.1.5 introduced the ng-if directive. That's the best solution for this particular problem. If you are using an older version of Angular, consider using angular-ui's ui-if directive.

If you arrived here looking for answers to the general question of "conditional logic in templates" also consider:

• 1.1.5 also introduced a ternary operator
• ng-switch can be used to conditionally add/remove elements from the DOM
• see also How do I conditionally apply CSS styles in AngularJS?

Original answer:

Here is a not-so-great "ng-if" directive:

myApp.directive('ngIf', function() {
    return {
        link: function(scope, element, attrs) {
            if(scope.$eval(attrs.ngIf)) {
                // remove '<div ng-if...></div>'
                element.replaceWith(element.children())
            } else {
                element.replaceWith(' ')
            }
        }
    }
});

that allows for this HTML syntax:

<div ng-repeat="message in data.messages" ng-class="message.type">
   <hr>
   <div ng-if="showFrom(message)">
       <div>From: {{message.from.name}}</div>
   </div>    
   <div ng-if="showCreatedBy(message)">
      <div>Created by: {{message.createdBy.name}}</div>
   </div>    
   <div ng-if="showTo(message)">
      <div>To: {{message.to.name}}</div>
   </div>    
</div>

Fiddle.

replaceWith() is used to remove unneeded content from the DOM.

Also, as I mentioned on Google+, ng-style can probably be used to conditionally load background images, should you want to use ng-show instead of a custom directive. (For the benefit of other readers, Jon stated on Google+: "both methods use ng-show which I'm trying to avoid because it uses display:none and leaves extra markup in the DOM. This is a particular problem in this scenario because the hidden element will have a background image which will still be loaded in most browsers.").
See also How do I conditionally apply CSS styles in AngularJS?

The angular-ui ui-if directive watches for changes to the if condition/expression. Mine doesn't. So, while my simple implementation will update the view correctly if the model changes such that it only affects the template output, it won't update the view correctly if the condition/expression answer changes.

E.g., if the value of a from.name changes in the model, the view will update. But if you delete $scope.data.messages[0].from, the from name will be removed from the view, but the template will not be removed from the view because the if-condition/expression is not being watched.

I would like to quote an answer given by Microsoft support engineer at here:-

Hi Henny, MSVCR110.dll is the Microsoft Visual C++ Redistributable dll that is needed for projects built with Visual Studio 2011. The dll letters spell this out. MS = Microsoft, V = Visual, C = C++, R = Redistributable For Winroy to get started, this file is probably needed. This error appears when you wish to run a software which require the Microsoft Visual C++ Redistributable 2012. The redistributable can easily be downloaded on the Microsoft website as x86 or x64 edition. Depending on the software you wish to install you need to install either the 32 bit or the 64 bit version. Refer the following link: http://www.microsoft.com/en-us/download/details.aspx?id=30679# Please let us know if the issue persists. We will be happy to assist you further.

As of jackson 2.7.4 (or earlier maybe), the class is in jacskon-jaxrs-base.jar, which is contained in jackson-jaxrs-json-provider

Arrays.sort(stringArray); This sorts the string array based on the Unicode characters values. All strings that contain uppercase characters at the beginning of the string will be at the top of the sorted list alphabetically followed by all strings with lowercase characters. Hence if the array contains strings beginning with both uppercase characters and lowercase characters, the sorted array would not return a case insensitive order alphabetical list

String[] strArray = { "Carol", "bob", "Alice" };
Arrays.sort(strList);
System.out.println(Arrays.toString(hotel));

Output is : Alice, Carol, bob,

If you require the Strings to be sorted without regards to case, you'll need a second argument, a Comparator, for Arrays.sort(). Such a comparator has already been written for us and can be accessed as a static on the String class named CASE_INSENSITIVE_ORDER.

String[] strArray = { "Carol", "bob", "Alice" };
Arrays.sort(stringArray, String.CASE_INSENSITIVE_ORDER);
System.out.println(Arrays.toString(strArray ));

Output is : Alice, bob, Carol

Trying to get this on a mobile device requires a few more steps. screen.availWidth stays the same regardless of the orientation of the device.

Here is my solution for mobile:

function getOrientation(){
    return Math.abs(window.orientation) - 90 == 0 ? "landscape" : "portrait";
};
function getMobileWidth(){
    return getOrientation() == "landscape" ? screen.availHeight : screen.availWidth;
};
function getMobileHeight(){
    return getOrientation() == "landscape" ? screen.availWidth : screen.availHeight;
};

I had a similar problem after messing with foreign key constraints. One of my tables (notes) was gone and one kept coming back (tasks) even after dropping it in MySQL, preventing me from running: php artisan migrate/refresh/reset, which produced the above 42s01 exception.

What I did to solve it was ssh into vagrant then go into MySQL (vagrant ssh, mysql -u homestead -p secret), then: DROP DATABASE homestead; Then CREATE DATABASE homestead; Then exit mysql and run:php artisan migrate`.

Obviously this solution will not work for people not using vagrant/homestead. Not claiming in any way this is a proper workflow but it solved my problem which looks a lot like the above one.

IIRC, something like:

set tabstop=2 shiftwidth=2 expandtab

should do the trick. If you already have tabs, then follow it up with a nice global RE to replace them with double spaces.

If you already have tabs you want to replace,

:retab

Try to add display:block; to your test1

Adding you a quick example using git plugin GitSCM:

    checkout([
        $class: 'GitSCM', 
        branches: [[name: '*/master']], 
        doGenerateSubmoduleConfigurations: false, 
        extensions: [[$class: 'CleanCheckout']], 
        submoduleCfg: [], 
        userRemoteConfigs: [[credentialsId: '<gitCredentials>', url: '<gitRepoURL>']]
    ])

in your pipeline

stage('checkout'){
    steps{
        script{
            checkout
        }
    }
}

You can iterate over "a file", which produces lines, including the trailing newline character. To make a "virtual file" out of a string, you can use StringIO:

import io  # for Py2.7 that would be import cStringIO as io

for line in io.StringIO(foo):
    print(repr(line))

Here's some pseudocode. You can cut same recursive calls by storing the values for each call as you go and before recursive call checking if the call value is already present.

The following algorithm will have all the subsets excluding the empty set.

list * subsets(string s, list * v){
    if(s.length() == 1){
        list.add(s);    
        return v;
    }
    else
    {
        list * temp = subsets(s[1 to length-1], v);     
        int length = temp->size();

        for(int i=0;i<length;i++){
            temp.add(s[0]+temp[i]);
        }

        list.add(s[0]);
        return temp;
    }
}

This can be done with outer to get a metrix of equalities followed by rowSums, with an obvious meaning.
In order to have the counts and numbers in the same dataset, a data.frame is first created. This step is not needed if you want separate input and output.

You can use the lineTo() method same as: var objctx = canvas.getContext('2d');

        objctx.beginPath();
        objctx.moveTo(75, 50);
        objctx.lineTo(175, 50);
        objctx.lineTo(200, 75);
        objctx.lineTo(175, 100);
        objctx.lineTo(75, 100);
        objctx.lineTo(50, 75);
        objctx.closePath();
        objctx.fillStyle = "rgb(200,0,0)";
        objctx.fill();

if you not want to fill the polygon use the stroke() method in the place of fill()

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

Here's a function that finds the dictionary's index position if it exists.

dicts = [{'id':'1234','name':'Jason'},
         {'id':'2345','name':'Tom'},
         {'id':'3456','name':'Art'}]

    class Null: pass
    for i, d in enumerate(dicts):
        if d.get(key, Null) == value:
            return i
    else:
        raise ValueError('no dict with the key and value combination found')

You're looking for Discriminated Unions which are a language feature of F#, but you can achieve a similar effect by using a library I made, called OneOf

https://github.com/mcintyre321/OneOf

The major advantage over switch (and if and exceptions as control flow) is that it is compile-time safe - there is no default handler or fall through

void Foo(OneOf<A, B> o)
{
    o.Switch(
        a => a.Hop(),
        b => b.Skip()
    );
}

If you add a third item to o, you'll get a compiler error as you have to add a handler Func inside the switch call.

You can also do a .Match which returns a value, rather than executes a statement:

double Area(OneOf<Square, Circle> o)
{
    return o.Match(
        square => square.Length * square.Length,
        circle => Math.PI * circle.Radius * circle.Radius
    );
}

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

var express = require('express');
var app = express();

app.get('*',function (req, res) {
    res.redirect('https://<domain>' + req.url);
});

app.listen(80);

This is what we use and it works great!

It maybe solve your problem, check your files access level

$ sudo chmod -R 777 /"your files location"

Here is how you can easily remove the $$hashKey from the object:

$scope.myNewObject = JSON.parse(angular.toJson($scope.myObject))

$scope.myObject - Refers to the Object that you want to perform the operation upon i.e. remove the $$hashKey from

$scope.myNewObject - Assign the modified original object to the new object so it can be used as necessary

If both the tables have the same schema then use this query: insert into database_name.table_name select * from new_database_name.new_table_name where='condition'

Replace database_name with the name of your 1st database and table_name with the name of table you want to copy from also replace new_database_name with the name of your other database where you wanna copy and new_table_name is the name of the table.

one of the simplest ways to create a string matrix is as follow :

x = [ {'first string'} {'Second parameter} {'Third text'} {'Fourth component'} ]

For Swift 3.0

String(describing: <Class-Name>.self)

For Swift 2.0 - 2.3

String(<Class-Name>)

Yes, it's historical. Without it, it creates an old-style class.

If you use type() on an old-style object, you just get "instance". On a new-style object you get its class.

There are more aspects to this.

You can achieve TLS (some keep saying SSL) with a certificate, self-signed or not.

To have a green bar for a self-signed certificate, you also need to become the Certificate Authority (CA). This aspect is missing in most resources I found on my journey to achieve the green bar in my local development setup. Becoming a CA is as easy as creating a certificate.

This resource covers the creation of both the CA certificate and a Server certificate and resulted my setup in showing a green bar on localhost Chrome, Firefox and Edge: https://ram.k0a1a.net/self-signed_https_cert_after_chrome_58

Please note: in Chrome you need to add the CA Certificate to your trusted authorities.

The % (modulo) operator yields the remainder from the division of the first argument by the second. The numeric arguments are first converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the absolute value of the result is strictly smaller than the absolute value of the second operand [2].

Taken from http://docs.python.org/reference/expressions.html

Example 1: 6%2 evaluates to 0 because there's no remainder if 6 is divided by 2 ( 3 times ).

Example 2: 7%2 evaluates to 1 because there's a remainder of 1 when 7 is divided by 2 ( 3 times ).

So to summarise that, it returns the remainder of a division operation, or 0 if there is no remainder. So 6%2 means find the remainder of 6 divided by 2.

Check the LOB segment name from dba_lobs using the table name.

select TABLE_NAME,OWNER,COLUMN_NAME,SEGMENT_NAME from dba_lobs where TABLE_NAME='<<TABLE NAME>>';

Now use the segment name to find the bytes used in dba_segments.

select s.segment_name, s.partition_name, bytes/1048576 "Size (MB)"
from dba_segments s, dba_lobs l
where s.segment_name = l.segment_name
and s.owner = '<< OWNER >> ' order by s.segment_name, s.partition_name;

1. Check the trees.config file which located in config folder... sometimes (I don't know why) this file became to be empty like someone delete the content inside... keep backup up of this file in your local pc then when this error appear - replace the server file with your local file. This is what i do when this error happened.

2. check the available space on the server. sometimes this is the problem.

Good luck.

Here is an example using RSA.

Important: There is a limit to the size of data you can encrypt with the RSA encryption, KeySize - MinimumPadding. e.g. 256 bytes (assuming 2048 bit key) - 42 bytes (min OEAP padding) = 214 bytes (max plaintext size)

Replace your_rsa_key with your RSA key.

var provider = new System.Security.Cryptography.RSACryptoServiceProvider();
provider.ImportParameters(your_rsa_key);

var encryptedBytes = provider.Encrypt(
    System.Text.Encoding.UTF8.GetBytes("Hello World!"), true);

string decryptedTest = System.Text.Encoding.UTF8.GetString(
    provider.Decrypt(encryptedBytes, true));

actually you want to get the object from the Spring engine, where the engine already maintaining the object of your required class at that starting of the spring application(Initialization of the Spring engine).Now the thing is you just have to get that object to a reference.

in a service class

@Autowired
private ApplicationContext context;

SomeClass sc = (SomeClass)context.getBean(SomeClass.class);

now in the reference of the sc you are having the object. Hope explained well. If any doubt please let me know.

You can mark properties with readonly modifier in your declaration:

export class MyClass {
  public static readonly MY_PUBLIC_CONSTANT = 10;
  private static readonly myPrivateConstant = 5;
}

I landed on the same exact exception because I forgot to activate the virtual environment.

When I have a similar issue when reading text files i use...

f = open('file','rt', errors='ignore')

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

Reset single select field to default option.

<select id="name">
    <option>select something</option>
    <option value="1" >something 1</option>
    <option value="2" selected="selected" >Default option</option>
</select>
<script>
    $('name').val( $('name').find("option[selected]").val() );
</script>

Or if you want to reset all form fields to the default option:

<script>
    $('select').each( function() {
        $(this).val( $(this).find("option[selected]").val() );
    });
</script>

I'd use STUFF to insert dividing chars and then use CONVERT with the appropriate style. Something like this:

DECLARE @dt VARCHAR(100)='111290';
SELECT CONVERT(DATETIME,STUFF(STUFF(@dt,3,0,'/'),6,0,'/'),3)

First you use two times STUFF to get 11/12/90 instead of 111290, than you use the 3 to convert this to datetime (or any other fitting format: use . for german, - for british...) More details on CAST and CONVERT

Best was, to store date and time values properly.

• This should be either "universal unseparated format" yyyyMMdd
• or (especially within XML) it should be ISO8601: yyyy-MM-dd or yyyy-MM-ddThh:mm:ss More details on ISO8601

Any culture specific format will lead into troubles sooner or later...

Use BOOST_BINARY (Yes, you can use it in C).

#include <boost/utility/binary.hpp>

I added my anwer because I have getting the same error while configure ODDO9 source code in local and its need the exe to run while run exe, I got the same error.

From yesterday I was configure oddo 9.0 (section :- "Python dependencies listed in the requirements.txt file.") and its need to run PIP exe as

C:\YourOdooPath> C:\Python27\Scripts\pip.exe install -r requirements.txt

My oddo path is :- D:\Program Files (x86)\Odoo 9.0-20151014 My pip location is :- D:\Program Files (x86)\Python27\Scripts\pip.exe

So I open command prompt and go to above oddo path and try to run pip exe with these combination, but not given always above error.

1. D:\Program Files (x86)\Python27\Scripts\pip.exe install -r requirements.txt

2. "D:\Program Files (x86)\Python27\Scripts\pip.exe install -r requirements.txt" Python27\Scripts\pip.exe install -r requirements.txt

3. "Python27/Scripts/pip.exe install -r requirements.txt"

I resolved my issue by the @user4154243 answer, thanks for that.

Step 1: Add variable(if your path is not comes in variable's path).

Step 2: Go to command prompt, open oddo path where you installed.

Step 3: run this command python -m pip install XXX will run and installed the things.

As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)

Duration column = End - Start

1. Once done, plot your stacked bar chart using the entire data.
2. Mark start and end range to no fill.
3. Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))

What's the difference between Perl's backticks (`), system, and exec?

exec -> exec "command"; ,
system -> system("command"); and 
backticks -> print `command`;

exec

exec executes a command and never resumes the Perl script. It's to a script like a return statement is to a function.

If the command is not found, exec returns false. It never returns true, because if the command is found, it never returns at all. There is also no point in returning STDOUT, STDERR or exit status of the command. You can find documentation about it in perlfunc, because it is a function.

E.g.:

#!/usr/bin/perl
print "Need to start exec command";
my $data2 = exec('ls');
print "Now END exec command";
print "Hello $data2\n\n";

In above code, there are three print statements, but due to exec leaving the script, only the first print statement is executed. Also, the exec command output is not being assigned to any variable.

Here, only you're only getting the output of the first print statement and of executing the ls command on standard out.

system

system executes a command and your Perl script is resumed after the command has finished. The return value is the exit status of the command. You can find documentation about it in perlfunc.

E.g.:

#!/usr/bin/perl
print "Need to start system command";
my $data2 = system('ls');
print "Now END system command";
print "Hello $data2\n\n";

In above code, there are three print statements. As the script is resumed after the system command, all three print statements are executed.

Also, the result of running system is assigned to data2, but the assigned value is 0 (the exit code from ls).

Here, you're getting the output of the first print statement, then that of the ls command, followed by the outputs of the final two print statements on standard out.

backticks (`)

Like system, enclosing a command in backticks executes that command and your Perl script is resumed after the command has finished. In contrast to system, the return value is STDOUT of the command. qx// is equivalent to backticks. You can find documentation about it in perlop, because unlike system and exec, it is an operator.

E.g.:

#!/usr/bin/perl
print "Need to start backticks command";
my $data2 = `ls`;
print "Now END system command";
print "Hello $data2\n\n";

In above code, there are three print statements and all three are being executed. The output of ls is not going to standard out directly, but assigned to the variable data2 and then printed by the final print statement.

Sys.sleep() will not work if the CPU usage is very high; as in other critical high priority processes are running (in parallel).

This code worked for me. Here I am printing 1 to 1000 at a 2.5 second interval.

for (i in 1:1000)
{
  print(i)
  date_time<-Sys.time()
  while((as.numeric(Sys.time()) - as.numeric(date_time))<2.5){} #dummy while loop
}

expanding on @leaf 's answer, here's one that can take multiple characters:

var trim = function (s, t) {
  var tr, sr
  tr = t.split('').map(e => `\\\\${e}`).join('')
  sr = s.replace(new RegExp(`^[${tr}]+|[${tr}]+$`, 'g'), '')
  return sr
}

Well you can convert one byte (unsigned char) at a time into a array like so

char buffer [17];
buffer[16] = 0;
for(j = 0; j < 8; j++)
    sprintf(&buffer[2*j], "%02X", data[j]);

This is a sample code I used to counter the problem.

\begin{frame}{Topic 1}

\end{frame}

re.match is anchored at the beginning of the string. That has nothing to do with newlines, so it is not the same as using ^ in the pattern.

As the re.match documentation says:

If zero or more characters at the beginning of string match the regular expression pattern, return a corresponding MatchObject instance. Return None if the string does not match the pattern; note that this is different from a zero-length match.

Note: If you want to locate a match anywhere in string, use search() instead.

re.search searches the entire string, as the documentation says:

Scan through string looking for a location where the regular expression pattern produces a match, and return a corresponding MatchObject instance. Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string.

So if you need to match at the beginning of the string, or to match the entire string use match. It is faster. Otherwise use search.

The documentation has a specific section for match vs. search that also covers multiline strings:

Python offers two different primitive operations based on regular expressions: match checks for a match only at the beginning of the string, while search checks for a match anywhere in the string (this is what Perl does by default).

Note that match may differ from search even when using a regular expression beginning with '^': '^' matches only at the start of the string, or in MULTILINE mode also immediately following a newline. The “match” operation succeeds only if the pattern matches at the start of the string regardless of mode, or at the starting position given by the optional pos argument regardless of whether a newline precedes it.

Now, enough talk. Time to see some example code:

# example code:
string_with_newlines = """something
someotherthing"""

import re

print re.match('some', string_with_newlines) # matches
print re.match('someother', 
               string_with_newlines) # won't match
print re.match('^someother', string_with_newlines, 
               re.MULTILINE) # also won't match
print re.search('someother', 
                string_with_newlines) # finds something
print re.search('^someother', string_with_newlines, 
                re.MULTILINE) # also finds something

m = re.compile('thing$', re.MULTILINE)

print m.match(string_with_newlines) # no match
print m.match(string_with_newlines, pos=4) # matches
print m.search(string_with_newlines, 
               re.MULTILINE) # also matches

A solution similar to the one of @Nick G. by using filter, but make the parameter meaningful:

Implement an filter called relativedate which calculate the date relative to current date by the given parameter as diff. As a result, (0 | relativedate) means today and (1 | relativedate) means tomorrow.

.filter('relativedate', ['$filter', function ($filter) {
  return function (rel, format) {
    let date = new Date();
    date.setDate(date.getDate() + rel);
    return $filter('date')(date, format || 'yyyy-MM-dd')
  };
}]);

and your html:

<div ng-app="myApp">
    <div>Yesterday: {{-1 | relativedate}}</div>
    <div>Today: {{0 | relativedate}}</div>
    <div>Tomorrow: {{1 | relativedate}}</div>
</div>

Use Apache commons beanutils:

static void copyProperties(Object dest, Object orig) -Copy property values from the origin bean to the destination bean for all cases where the property names are the same.

http://commons.apache.org/proper/commons-beanutils/

how remote is that url ? is it from the same domain ? the code looks okay

try this

$.ajaxSetup({async:false});
$.get(remote_url, function(data) { remote = data; });
// or
remote = $.get(remote_url).responseText;

It seems that you've omitted the value attribute in HTML markup.

Add it there as <input value="" ... >.

You can use the html property: http://jsfiddle.net/UBr6c/

My <a href="#" title="This is a<br />test...<br />or not" class="my_tooltip">Tooltip</a> test.

$('.my_tooltip').tooltip({html: true})

df.sort($"ColumnName".desc).show()

For a multidimensional array in PHP4 you can use the following addition to the code posted by Udo G:

function js_str($s) {
   return '"'.addcslashes($s, "\0..\37\"\\").'"';
}

function js_array($array, $keys_array) {
  foreach ($array as $key => $value) {
    $new_keys_array = $keys_array;
    $new_keys_array[] = $key;
    if(is_array($value)) {          
      echo 'javascript_array';
      foreach($new_keys_array as $key) {
        echo '["'.$key.'"]';
      }
      echo ' = new Array();';

      js_array($value, $new_keys_array);
    } else {
      echo 'javascript_array';
      foreach($new_keys_array as $key) {
        echo '["'.$key.'"]';
      }
      echo ' = '.js_str($value).";";                        
    }
  } 
}

echo 'var javascript_array = new Array();';
js_array($php_array, array());

Excel has no way of gathering that attribute with it's built-in functions. If you're willing to use some VB, all your color-related questions are answered here:

http://www.cpearson.com/excel/colors.aspx

Example form the site:

The SumColor function is a color-based analog of both the SUM and SUMIF function. It allows you to specify separate ranges for the range whose color indexes are to be examined and the range of cells whose values are to be summed. If these two ranges are the same, the function sums the cells whose color matches the specified value. For example, the following formula sums the values in B11:B17 whose fill color is red.

=SUMCOLOR(B11:B17,B11:B17,3,FALSE)

I solved this issue by using sudo ie

sudo yarn start

or

sudo npm start

Perhaps mathJAX is the ticket. It's built on jsMath, a 2004 vintage JavaScript library.

As of 5-Feb-2015 I'd switch to recommend KaTeX - most performant Javascript LaTeX library from Khan Academy.

You can use formatDate() to format the date in services or component ts. syntax:-

    formatDate(value: string | number | Date, format: string, locale: string, timezone?: string): string

import the formatDate() from common module like this,

    import { formatDate } from '@angular/common';

and just use it in the class like this ,

    formatDate(new Date(), 'MMMM dd yyyy', 'en');

You can also use the predefined format options provided by angular like this ,

    formatDate(new Date(), 'shortDate', 'en');

You can see all other predefined format options here ,

https://angular.io/api/common/DatePipe

Well I tried Nathan Koop's answer and it didn't work for me. I changed it to the following and it did work:

SELECT COUNT(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'table_name'

It also didn't work if I put USE 'database_name' nor WHERE table_catalog = 'database_name' AND table_name' = 'table_name'. I actually will be happy to know why.

I finally found a working version for firefox, chrome & default navigator in android (4.2 tested only):

function getGeoLocation() {
        var options = null;
        if (navigator.geolocation) {
            if (browserChrome) //set this var looking for Chrome un user-agent header
                options={enableHighAccuracy: false, maximumAge: 15000, timeout: 30000};
            else
                options={maximumAge:Infinity, timeout:0};
            navigator.geolocation.getCurrentPosition(getGeoLocationCallback,
                    getGeoLocationErrorCallback,
                   options);
        }
    }

Try this, it is updating the current location, and it works fine.

        public void onLocationChanged(@NonNull Location location) {               
        //here we update the location on the map
        
        LatLng myActualLocation = new LatLng(location.getLatitude(), location.getLongitude());
        
        if (markerName!=null){  // marker name is declared as a gloval variable.
            markerName.remove();
        }
        
        markerName = mMap.addMarker(new MarkerOptions().position(myActualLocation).title("Marker Miami").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE)));
        
        // mMap.addMarker(new MarkerOptions().position(myActualLocation).title("Marker Miami").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE)));
        mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myActualLocation,18));
        
        }

As stated in other answers, the simplest method is to uniquely identify the root element (by ID or class name) and use the direct descendent selector.

$('ul.topMenu > li > a')

However, I came across this question in search of a solution which would work on unnamed elements at varying depths of the DOM.

This can be achieved by checking each element, and ensuring it does not have a parent in the list of matched elements. Here is my solution, wrapped in a jQuery selector 'topmost'.

jQuery.extend(jQuery.expr[':'], {
  topmost: function (e, index, match, array) {
    for (var i = 0; i < array.length; i++) {
      if (array[i] !== false && $(e).parents().index(array[i]) >= 0) {
        return false;
      }
    }
    return true;
  }
});

Utilizing this, the solution to the original post is:

$('ul:topmost > li > a')

// Or, more simply:
$('li:topmost > a')

Complete jsFiddle available here.

Using filter() and lambda would provide a neat and terse method of removing unwanted values:

newEmails = list(filter(lambda x : x != '[email protected]', emails))

This does not modify emails. It creates the new list newEmails containing only elements for which the anonymous function returned True.

Works fine even with camel case: 'someText in YourPage'

public static class StringExtensions
{
    /// <summary>
    /// Title case example: 'Some Text In Your Page'.
    /// </summary>
    /// <param name="text">Support camel and title cases combinations: 'someText in YourPage'</param>
    public static string ToTitleCase(this string text)
    {
        if (string.IsNullOrEmpty(text))
        {
            return text;
        }
        var result = string.Empty;
        var splitedBySpace = text.Split(new[]{ ' ' }, StringSplitOptions.RemoveEmptyEntries);
        foreach (var sequence in splitedBySpace)
        {
            // let's check the letters. Sequence can contain even 2 words in camel case
            for (var i = 0; i < sequence.Length; i++)
            {
                var letter = sequence[i].ToString();
                // if the letter is Big or it was spaced so this is a start of another word
                if (letter == letter.ToUpper() || i == 0)
                {
                    // add a space between words
                    result += ' ';
                }
                result += i == 0 ? letter.ToUpper() : letter;
            }
        }            
        return result.Trim();
    }
}

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

If you want to send an arbitrary amount of data to your server, POST is the only reliable method to do that. GET would also be possible but clients and servers allow just a limited URL length (something like 2048 characters).

10 years later, you have an alternative to tar, illustrated with Git 2.30 (Q1 2021), which uses "git archive"^(man) to produce the release tarball instead of tar.
(You don't need Git 2.30 to apply that alternative)

See commit 4813277 (11 Oct 2020), and commit 93e7031 (10 Oct 2020) by René Scharfe (rscharfe).
^{(Merged by Junio C Hamano -- gitster -- in commit 63e5273, 27 Oct 2020)}

Makefile: use git init/add/commit/archive for dist-doc

^{Signed-off-by: René Scharfe}

Reduce the dependency on external tools by generating the distribution archives for HTML documentation and manpages using git^(man) commands instead of tar. This gives the archive entries the same meta data as those in the dist archive for binaries.

So instead of:

tar cf ../archive.tar .

You can do using Git only:

git -C workspace init
git -C workspace add .
git -C workspace commit -m workspace
git -C workspace archive --format=tar --prefix=./ HEAD^{tree} > workspace.tar
rm -Rf workspace/.git

That was initially proposed because, as explained here, some exotic platform might have an old tar distribution with lacking options.

Unfortunately, I found this link which appears to indicate that we cannot cache these locally, therefore making this question moot.

http://support.google.com/enterprise/doc/gme/terms/maps_purchase_agreement.html

4.4 Cache Restrictions. Customer may not pre-fetch, retrieve, cache, index, or store any Content, or portion of the Services with the exception being Customer may store limited amounts of Content solely to improve the performance of the Customer Implementation due to network latency, and only if Customer does so temporarily, securely, and in a manner that (a) does not permit use of the Content outside of the Services; (b) is session-based only (once the browser is closed, any additional storage is prohibited); (c) does not manipulate or aggregate any Content or portion of the Services; (d) does not prevent Google from accurately tracking Page Views; and (e) does not modify or adjust attribution in any way.

So it appears we cannot use Google map tiles offline, legally.

Not sure, but what I think you're looking for is to create a java.util.Date from a String, then convert that java.util.Date to a java.sql.Date.

try this:

private static java.sql.Date getCurrentDate(String date) {

    java.util.Date today;
    java.sql.Date rv = null;
    try {

        SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");
        today = format.parse(date);
        rv = new java.sql.Date(today.getTime());
        System.out.println(rv.getTime());

    } catch (Exception e) {
        System.out.println("Exception: " + e.getMessage());
    } finally {
        return rv;
    }

}    

Will return a java.sql.Date object for setDate();

The function above will print out a long value:

1375934400000

You can also easily pass parameters to modal controller by added a new property with instance of modal and get it to modal controller. For example:

Following is my click event on which i want to open modal view.

 $scope.openMyModalView = function() {
            var modalInstance = $modal.open({
                    templateUrl: 'app/userDetailView.html',
                    controller: 'UserDetailCtrl as userDetail'
                });
                // add your parameter with modal instance
                modalInstance.userName = 'xyz';
        };

Modal Controller:

angular.module('myApp').controller('UserDetailCtrl', ['$modalInstance',
                function ($modalInstance) {
                    // get your parameter from modal instance
                    var currentUser = $modalInstance.userName;
                    // do your work...
                }]);

I should like to contribute the modern answer. This involves using java.time, the modern Java date and time API, and not the old Date nor Calendar except where there’s no way to avoid it.

Your issue is very likely really a timezone issue. When it is Tue Aug 09 00:00:00 IST 2011, in time zones west of IST midnight has not yet been reached. It is still Aug 8. If for example your API for putting the date into Excel expects UTC, the date will be the day before the one you intended. I believe the real and good solution is to produce a date-time of 00:00 UTC (or whatever time zone or offset is expected and used at the other end).

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    ZonedDateTime utcDateDime = yourDate.atStartOfDay(ZoneOffset.UTC);
    System.out.println(utcDateDime);

This prints

2018-02-27T00:00Z

Z means UTC (think of it as offset zero from UTC or Zulu time zone). Better still, of course, if you could pass the LocalDate from the first code line to Excel. It doesn’t include time-of-day, so there is no confusion possible. On the other hand, if you need an old-fashioned Date object for that, convert just before handing the Date on:

    Date oldfashionedDate = Date.from(utcDateDime.toInstant());
    System.out.println(oldfashionedDate);

On my computer this prints

Tue Feb 27 01:00:00 CET 2018

Don’t be fooled, it is correct. My time zone (Central European Time) is at offset +01:00 from UTC in February (standard time), so 01:00:00 here is equal to 00:00:00 UTC. It’s just Date.toString() grabbing the JVMs time zone and using it for producing the string.

How can I set it to something like 5:30 pm?

To answer your direct question directly, if you have a ZonedDateTime, OffsetDateTime or LocalDateTime, in all of these cases the following will accomplish what you asked for:

    yourDateTime = yourDateTime.with(LocalTime.of(17, 30));

If yourDateTime was a LocalDateTime of 2018-02-27T00:00, it will now be 2018-02-27T17:30. Similarly for the other types, only they include offset and time zone too as appropriate.

If you only had a date, as in the first snippet above, you can also add time-of-day information to it:

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    LocalDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30));

For most purposes you should prefer to add the time-of-day in a specific time zone, though, for example

    ZonedDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30))
            .atZone(ZoneId.of("Asia/Kolkata"));

This yields 2018-02-27T17:30+05:30[Asia/Kolkata].

Date and Calendar vs java.time

The Date class that you use as well as Calendar and SimpleDateFormat used in the other answers are long outdated, and SimpleDateFormat in particular has proven troublesome. In all cases the modern Java date and time API is so much nicer to work with. Which is why I wanted to provide this answer to an old question that is still being visited.

Link: Oracle Tutorial Date Time, explaining how to use java.time.

I am stuck with same issue and find the easiest way to do this...

//Html
<button type="button" onclick="history.back()">Back</button>

OR

//Html
<button type="button" ng-click="goBack()">Back</button>

//JS
$scope.goBack = function() {
  window.history.back();
};

(If you want it to be more testable, inject the $window service into your controller and use $window.history.back()).

mv server.log logs/$(date -d "today" +"%Y%m%d%H%M").log

The reason is that the Scanner class is designed for reading in whitespace-separated tokens. It's a convenience class that wraps an underlying input stream. Before scanner all you could do was read in single bytes, and that's a big pain if you want to read words or lines. With Scanner you pass in System.in, and it does a number of read() operations to tokenize the input for you. Reading a single character is a more basic operation. Source

You can use (char) System.in.read();.

I had the same requirements to create a kind of step progress tracker so I created a JavaScript plugin for that purpose. Here is the JsFiddle for the demo for this step progress tracker. You can access its code on GitHub as well.

What it basically does is, it takes the json data(in a particular format described below) as input and creates the progress tracker based on that. Highlighted steps indicates the completed steps.

It's html will somewhat look like shown below with default CSS but you can customize it as per the theme of your application. There is an option to show tool-tip text for each steps as well.

Here is some code snippet for that:

//container div 
<div id="tracker1" style="width: 700px">
</div>

//sample JSON data
var sampleJson1 = {
ToolTipPosition: "bottom",
data: [{ order: 1, Text: "Foo", ToolTipText: "Step1-Foo", highlighted: true },
    { order: 2, Text: "Bar", ToolTipText: "Step2-Bar", highlighted: true },
    { order: 3, Text: "Baz", ToolTipText: "Step3-Baz", highlighted: false },
    { order: 4, Text: "Quux", ToolTipText: "Step4-Quux", highlighted: false }]
};    

//Invoking the plugin
$(document).ready(function () {
        $("#tracker1").progressTracker(sampleJson1);
    });

Hopefully it will be useful for somebody else as well!

It should be much faster to use Newton's method to calculate the Integer Square Root, then square this number and check, as you do in your current solution. Newton's method is the basis for the Carmack solution mentioned in some other answers. You should be able to get a faster answer since you're only interested in the integer part of the root, allowing you to stop the approximation algorithm sooner.

Another optimization that you can try: If the Digital Root of a number doesn't end in 1, 4, 7, or 9 the number is not a perfect square. This can be used as a quick way to eliminate 60% of your inputs before applying the slower square root algorithm.

If you happen to have ImageMagick installed, then you can use 'identify'. For example, you can call it like this:

path = "//folder/image.jpg"
dim = subprocess.Popen(["identify","-format","\"%w,%h\"",path], stdout=subprocess.PIPE).communicate()[0]
(width, height) = [ int(x) for x in re.sub('[\t\r\n"]', '', dim).split(',') ]

If you built the IPA using PhoneGap Build online you can download and install the IPA directly on your Ipad/Iphone by opening build.phonegap.com in Safari on the device, logging in and then clicking the iOS tab (the download ipa button). You will then be asked to install the app you built.

Direct link to this after logging in is: https://build.phonegap.com/apps/YOUR-BUILD-NUMBER/download/ios

leDbConnection connection = 
new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");

connection);

the problem is you're trying to use regex features not supported by grep. namely, your \d won't work. use this instead:

REGEX_DATE="^[[:digit:]]{2}[-/][[:digit:]]{2}[-/][[:digit:]]{4}$"
echo "$1" | grep -qE "${REGEX_DATE}"
echo $?

you need the -E flag to get ERE in order to use {#} style.

In my projects, we usually call server side method like this:

in JavaScript:

document.getElementById("UploadButton").click();

Server side control:

<asp:Button runat="server" ID="UploadButton" Text="" style="display:none;" OnClick="UploadButton_Click" />

C#:

protected void Upload_Click(object sender, EventArgs e)
{

}

I would just loop through your JRadioButtons and call isSelected(). If you really want to go from the ButtonGroup you can only get to the models. You could match the models to the buttons, but then if you have access to the buttons, why not use them directly?

Validate the INPUT.

$time = strtotime($_POST['dateFrom']);
if ($time) {
  $new_date = date('Y-m-d', $time);
  echo $new_date;
} else {
   echo 'Invalid Date: ' . $_POST['dateFrom'];
  // fix it.
}

I just had the same issue and the following code worked for me:

Hoping it will help!

string is by default Nullable ,you don't need to do anything to make string Nullable

There is a short solution too. Just run this in your app:

FacebookSdk.sdkInitialize(getApplicationContext());
Log.d("AppLog", "key:" + FacebookSdk.getApplicationSignature(this));

A longer one that doesn't need FB SDK (based on a solution here) :

public static void printHashKey(Context context) {
    try {
        final PackageInfo info = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_SIGNATURES);
        for (android.content.pm.Signature signature : info.signatures) {
            final MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            final String hashKey = new String(Base64.encode(md.digest(), 0));
            Log.i("AppLog", "key:" + hashKey + "=");
        }
    } catch (Exception e) {
        Log.e("AppLog", "error:", e);
    }
}

The result should end with "=" .

This is what I did.

Note: Please check App.js for the code.

This thread might be dead, but StyledMarker is available for API v3. Just bind the color change you want to the correct DOM event using the addDomListener() method. This example is pretty close to what you want to do. If you look at the page source, change:

google.maps.event.addDomListener(document.getElementById("changeButton"),"click",function() {
  styleIcon.set("color","#00ff00");
  styleIcon.set("text","Go");
});

to something like:

google.maps.event.addDomListener("mouseover",function() {
  styleIcon.set("color","#00ff00");
  styleIcon.set("text","Go");
});

That should be enough to get you moving along.

The Wikipedia page on DOM Events will also help you target the event that you want to capture on the client-side.

Good luck (if you still need it)

I found that this works and uses no joins:

DECLARE @ObjectName NVARCHAR(100)
SELECT @ObjectName = OBJECT_NAME([default_object_id]) FROM SYS.COLUMNS
WHERE [object_id] = OBJECT_ID('[tableSchema].[tableName]') AND [name] = 'columnName';
EXEC('ALTER TABLE [tableSchema].[tableName] DROP CONSTRAINT ' + @ObjectName)

Just make sure that columnName does not have brackets around it because the query is looking for an exact match and will return nothing if it is [columnName].

First of all, the space complexity of this loop is O(1) (the input is customarily not included when calculating how much storage is required by an algorithm).

So the question that I have is if its possible that an algorithm has different time complexity from space complexity?

Yes, it is. In general, the time and the space complexity of an algorithm are not related to each other.

Sometimes one can be increased at the expense of the other. This is called space-time tradeoff.

In the above solution, repeated here:

f = open('file.txt', 'r')

try:
    # do stuff with f
finally:
   f.close()

if something bad happens (you never know ...) after opening the file successfully and before the try, the file will not be closed, so a safer solution is:

f = None
try:
    f = open('file.txt', 'r')

    # do stuff with f

finally:
    if f is not None:
       f.close()

Hmm, I would use

window.location = 'http://localhost/index.html#?options=go_here';

I'm not exactly sure if that is what you mean.

This regular expression

^\w+(\s\w+)*$

will only allow a single space between words and no leading or trailing spaces.

Below is the explanation of the regular expression:

1. ^ Assert position at start of the string
2. \w+ Match any word character [a-zA-Z0-9_]
   1. Quantifier: + Between one and unlimited times, as many times as possible, giving back as needed [greedy]
3. 1st Capturing group (\s\w+)*
   1. Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy]
   2. \s Match any white space character [\r\n\t\f ]
   3. \w+ Match any word character [a-zA-Z0-9_]
      1. Quantifier: + Between one and unlimited times, as many times as possible, giving back as needed [greedy]
4. $ Assert position at end of the string

yum uses RPM, so the following command will list the contents of the installed package:

$ rpm -ql package-name

Try this::

sb_trim = Regex.Replace(stw, @"(\D+)\s+\$([\d,]+)\.\d+\s+(.)",
    m => string.Format(
        "{0},{1},{2}",
        m.Groups[1].Value,
        m.Groups[2].Value.Replace(",", string.Empty),
        m.Groups[3].Value));

This is about as clean an answer as you'll get, at least with regexes.

• (\D+): First capture group. One or more non-digit characters.
• \s+\$: One or more spacing characters, then a literal dollar sign ($).
• ([\d,]+): Second capture group. One or more digits and/or commas.
• \.\d+: Decimal point, then at least one digit.
• \s+: One or more spacing characters.
• (.): Third capture group. Any non-line-breaking character.

The second capture group additionally needs to have its commas stripped. You could do this with another regex, but it's really unnecessary and bad for performance. This is why we need to use a lambda expression and string format to piece together the replacement. If it weren't for that, we could just use this as the replacement, in place of the lambda expression:

"$1,$2,$3"

If your class users need all the methods and properties** List has, you should derive your class from it. If they don't need them, enclose the List and make wrappers for methods your class users actually need.

This is a strict rule, if you write a public API, or any other code that will be used by many people. You may ignore this rule if you have a tiny app and no more than 2 developers. This will save you some time.

For tiny apps, you may also consider choosing another, less strict language. Ruby, JavaScript - anything that allows you to write less code.

Based on the other answers, I looked into XmlTextWriter and came up with the following helper method:

static public string Beautify(this XmlDocument doc)
{
    StringBuilder sb = new StringBuilder();
    XmlWriterSettings settings = new XmlWriterSettings
    {
        Indent = true,
        IndentChars = "  ",
        NewLineChars = "\r\n",
        NewLineHandling = NewLineHandling.Replace
    };
    using (XmlWriter writer = XmlWriter.Create(sb, settings)) {
        doc.Save(writer);
    }
    return sb.ToString();
}

It's a bit more code than I hoped for, but it works just peachy.

Here is another way not depending on a library but using a regex.

You can use this single line:

text.matches("\\A\\p{ASCII}*\\z")

Whole example program:

public class Main {
    public static void main(String[] args) {
        char nonAscii = 0x00FF;
        String asciiText = "Hello";
        String nonAsciiText = "Buy: " + nonAscii;
        System.out.println(asciiText.matches("\\A\\p{ASCII}*\\z"));
        System.out.println(nonAsciiText.matches("\\A\\p{ASCII}*\\z"));
    }
}

Go to Start → Control Panel → System → Advanced system settings → advanced(tab) → Environment Variables → System Variables → New:

Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M

In Magento 1.9.4.0 and maybe all versions in 1.x use:

Mage::getStoreConfig('general/store_information/address');

and the following params, it depends what you want to get:

• general/store_information/name
• general/store_information/phone
• general/store_information/merchant_country
• general/store_information/address
• general/store_information/merchant_vat_number

One missing character from everyone's examples above is the termination character (\0). This is invisible to the MySQL console output and is not discoverable by any of the queries heretofore mentioned. The query to find it is simply:

select * from TABLE where COLUMN like '%\0%';

In my case the solution was simple:

I have defined the route at the very start of the route.php file.

After moving the named route to the bottom, my app finally saw it. It means that somehow the route was defined too early.

I think we should use click instead change

I am using unix system.

In eclipse project-> Properties -> Java Compiler -> Errors/Warning -> Forbidden Access(access rule) -> Turn it to warning/Ignore(Previously it was set to Error).

I had the same question, and have spent all day trying out different packages.

I had originally used matlibplot: and was not happy with either mapping categories to predefined colors; or grouping/aggregating then iterating through the groups (and still having to map colors). I just felt it was poor package implementation.

Seaborn wouldn't work on my case, and Altair ONLY works inside of a Jupyter Notebook.

The best solution for me was PlotNine, which "is an implementation of a grammar of graphics in Python, and based on ggplot2".

Below is the plotnine code to replicate your R example in Python:

from plotnine import *
from plotnine.data import diamonds

g = ggplot(diamonds, aes(x='carat', y='price', color='color')) + geom_point(stat='summary')
print(g)

So clean and simple :)

Re: craigts's response, for anyone having trouble with using either False or None parameters for index_col, such as in cases where you're trying to get rid of a range index, you can instead use an integer to specify the column you want to use as the index. For example:

df = pd.read_csv('file.csv', index_col=0)

The above will set the first column as the index (and not add a range index in my "common case").

Update

Given the popularity of this answer, I thought i'd add some context/ a demo:

# Setting up the dummy data
In [1]: df = pd.DataFrame({"A":[1, 2, 3], "B":[4, 5, 6]})

In [2]: df
Out[2]:
   A  B
0  1  4
1  2  5
2  3  6

In [3]: df.to_csv('file.csv', index=None)
File[3]:
A  B
1  4
2  5
3  6

Reading without index_col or with None/False will all result in a range index:

In [4]: pd.read_csv('file.csv')
Out[4]:
   A  B
0  1  4
1  2  5
2  3  6

# Note that this is the default behavior, so the same as In [4]
In [5]: pd.read_csv('file.csv', index_col=None)
Out[5]:
   A  B
0  1  4
1  2  5
2  3  6

In [6]: pd.read_csv('file.csv', index_col=False)
Out[6]:
   A  B
0  1  4
1  2  5
2  3  6

However, if we specify that "A" (the 0th column) is actually the index, we can avoid the range index:

In [7]: pd.read_csv('file.csv', index_col=0)
Out[7]:
   B
A
1  4
2  5
3  6

possibly if you want to just transfer data to be used by JavaScript then you can use Hash Tags like this

http://localhost/project/index.html#exist

so once when you are done retriving the data show the message and change the window.location.hash to a suitable value.. now whenever you ll refresh the page the hashtag wont be present
NOTE: when you will use this instead ot query strings the data being sent cannot be retrived/read by the server

sp_change_users_login is deprecated.

Much easier is:

ALTER USER usr1 WITH LOGIN = login1;

To expand on what @JoshuaMaddox said, in the MDN Learning Area, under the "Introduction to HTML" section, the Document and website structure sub-section says (bold/emphasis is by me):

Header

Usually a big strip across the top with a big heading and/or logo. This is where the main common information about a website usually stays from one webpage to another.

Navigation bar

Links to the site's main sections; usually represented by menu buttons, links, or tabs. Like the header, this content usually remains consistent from one webpage to another — having an inconsistent navigation on your website will just lead to confused, frustrated users. Many web designers consider the navigation bar to be part of the header rather than a individual component, but that's not a requirement; in fact some also argue that having the two separate is better for accessibility, as screen readers can read the two features better if they are separate.

For those like me who come to this page with this problem after updating Xcode but don't have an issue with the location setting, restarting my computer did the trick.

$criteria = new \Doctrine\Common\Collections\Criteria();
    $criteria->where($criteria->expr()->gt('id', 'id'))
        ->setMaxResults(1)
        ->orderBy(array("id" => $criteria::DESC));

$results = $articlesRepo->matching($criteria);

Note that you can use a variable in a slice:

l = ['a',' b',' c',' d',' e']
c_index = l.index("c")
l2 = l[:c_index]

This would put the first two entries of l in l2

If after the installation curl-dev luarocks does not see the headers:

find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/

Example example;

This is a declaration of a variable named example of type Example. This will default-initialize the object which involves calling its default constructor. The object will have automatic storage duration which means that it will be destroyed when it goes out of scope.

Example* example;

This is a declaration of a variable named example which is a pointer to an Example. In this case, default-initialization leaves it uninitialized - the pointer is pointing nowhere in particular. There is no Example object here. The pointer object has automatic storage duration.

Example* example = new Example();

This is a declaration of a variable named example which is a pointer to an Example. This pointer object, as above, has automatic storage duration. It is then initialized with the result of new Example();. This new expression creates an Example object with dynamic storage duration and then returns a pointer to it. So the example pointer is now pointing to that dynamically allocated object. The Example object is value-initialized which will call a user-provided constructor if there is one or otherwise initialise all members to 0.

Example* example = new Example;

This is similar to the previous line. The difference is that the Example object is default-initialized, which will call the default constructor of Example (or leave it uninitialized if it is not of class type).

A dynamically allocated object must be deleted (probably with delete example;).

Network-based operations cannot be run on the main thread. You need to run all network-based tasks on a child thread or implement AsyncTask.

This is how you run a task in a child thread:

new Thread(new Runnable(){
    @Override
    public void run() {
        try {
            // Your implementation goes here
        } 
        catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}).start();

I've had to do something like this when using commons-httpclient to access an internal https server with a self-signed certificate. Yes, our solution was to create a custom TrustManager that simply passed everything (logging a debug message).

This comes down to having our own SSLSocketFactory that creates SSL sockets from our local SSLContext, which is set up to have only our local TrustManager associated with it. You don't need to go near a keystore/certstore at all.

So this is in our LocalSSLSocketFactory:

static {
    try {
        SSL_CONTEXT = SSLContext.getInstance("SSL");
        SSL_CONTEXT.init(null, new TrustManager[] { new LocalSSLTrustManager() }, null);
    } catch (NoSuchAlgorithmException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    } catch (KeyManagementException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    }
}

public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    LOG.trace("createSocket(host => {}, port => {})", new Object[] { host, new Integer(port) });

    return SSL_CONTEXT.getSocketFactory().createSocket(host, port);
}

Along with other methods implementing SecureProtocolSocketFactory. LocalSSLTrustManager is the aforementioned dummy trust manager implementation.

Well, you can't install to the GAC using ClickOnce. This is documented in this MSDN article.

You can do it by using include_once() function in php. Construct a header part in the name of header.php and construct the footer part by footer.php. Finally include all the content in one file.

For example:

header.php

<html>
<title>
<link href="sample.css">

footer.php

</html>

So the final files look like

include_once("header.php") 

body content(The body content changes based on the file dynamically)

include_once("footer.php") 

It works for me.

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'

It is basically a comment. As we know, a number of people working on the same project must have knowledge about the code changes. We are making some notes in the program about the parameters.

What I would do is use this tool and step through where you are getting the exception

http://www.reflector.net/

Read this it will tell you how to create PDB's so you do not have to have all your references setup.

It is a trial and I am not related to redgate at all I just use there software.

To further add missing points here, as per the request by Jaskey

Database version is stored within the SQLite database file.

catch is the constructor

SQLiteOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version)

So when the database helper constructor is called with a name (2nd param), platform checks if the database exists or not and if the database exists, it gets the version information from the database file header and triggers the right call back

As already explained in the older answer, if the database with the name doesn't exists, it triggers onCreate.

Below explanation explains onUpgrade case with an example.

Say, your first version of application had the DatabaseHelper (extending SQLiteOpenHelper) with constructor passing version as 1 and then you provided an upgraded application with the new source code having version passed as 2, then automatically when the DatabaseHelper is constructed, platform triggers onUpgrade by seeing the file already exists, but the version is lower than the current version which you have passed.

Now say you are planing to give a third version of application with db version as 3 (db version is increased only when database schema is to be modified). In such incremental upgrades, you have to write the upgrade logic from each version incrementally for a better maintainable code

Example pseudo code below:

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
  switch(oldVersion) {
    case 1:
       //upgrade logic from version 1 to 2
    case 2:
       //upgrade logic from version 2 to 3
    case 3:
       //upgrade logic from version 3 to 4
       break;
    default:
       throw new IllegalStateException(
                "onUpgrade() with unknown oldVersion " + oldVersion);
  }
}

Notice the missing break statement in case 1 and 2. This is what I mean by incremental upgrade.

Say if the old version is 2 and new version is 4, then the logic will upgrade the database from 2 to 3 and then to 4

If old version is 3 and new version is 4, it will just run the upgrade logic for 3 to 4

You didn't mention how your backup was made, so the generic answer is: Usually with the psql tool.

Depending on what pg_dump was instructed to dump, the SQL file can have different sets of SQL commands. For example, if you instruct pg_dump to dump a database using --clean and --schema-only, you can't expect to be able to restore the database from that dump as there will be no SQL commands for COPYing (or INSERTing if --inserts is used ) the actual data in the tables. A dump like that will contain only DDL SQL commands, and will be able to recreate the schema but not the actual data.

A typical SQL dump is restored with psql:

psql (connection options here) database  < yourbackup.sql

or alternatively from a psql session,

psql (connection options here) database
database=# \i /path/to/yourbackup.sql

In the case of backups made with pg_dump -Fc ("custom format"), which is not a plain SQL file but a compressed file, you need to use the pg_restore tool.

If you're working on a unix-like, try this:

man psql
man pg_dump
man pg_restore

otherwise, take a look at the html docs. Good luck!

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

Cheers

I have just discovered a way to append text and its working fine at least.

 var text = 'Put any text here';
 $('#text').append(text);

You can change text according to your need.

Hope this helps.

I saw the answers here and although helpful, they weren't exactly what I wanted since I had to alter a lot of my code.

What worked out for me, was doing something like this:

function isSession(selector) {
    //line added for the var that will have the result
    var result = false;
    $.ajax({
        type: "POST",
        url: '/order.html',
        data: ({ issession : 1, selector: selector }),
        dataType: "html",
        //line added to get ajax response in sync
        async: false,
        success: function(data) {
            //line added to save ajax response in var result
            result = data;
        },
        error: function() {
            alert('Error occured');
        }
    });
    //line added to return ajax response
    return result;
}

Hope helps someone

You can write your own equals function:

• dicts are equal if: 1) all keys are equal, 2) all values are equal
• lists are equal if: all items are equal and in the same order
• primitives are equal if a == b

Because you're dealing with json, you'll have standard python types: dict, list, etc., so you can do hard type checking if type(obj) == 'dict':, etc.

Rough example (not tested):

def json_equals(jsonA, jsonB):
    if type(jsonA) != type(jsonB):
        # not equal
        return False
    if type(jsonA) == dict:
        if len(jsonA) != len(jsonB):
            return False
        for keyA in jsonA:
            if keyA not in jsonB or not json_equal(jsonA[keyA], jsonB[keyA]):
                return False
    elif type(jsonA) == list:
        if len(jsonA) != len(jsonB):
            return False
        for itemA, itemB in zip(jsonA, jsonB):
            if not json_equal(itemA, itemB):
                return False
    else:
        return jsonA == jsonB

Updated for Swift 3 and above:

//1. Create the alert controller.
let alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .alert)

//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
    textField.text = "Some default text"
}

// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
    let textField = alert.textFields![0] // Force unwrapping because we know it exists.
    print("Text field: \(textField.text)")
}))

// 4. Present the alert.
self.present(alert, animated: true, completion: nil)

Swift 2.x

Assuming you want an action alert on iOS:

//1. Create the alert controller.            
var alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .Alert)

//2. Add the text field. You can configure it however you need.
alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in
    textField.text = "Some default text."
})

//3. Grab the value from the text field, and print it when the user clicks OK. 
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: { [weak alert] (action) -> Void in
    let textField = alert.textFields![0] as UITextField
    println("Text field: \(textField.text)")
}))

// 4. Present the alert.
self.presentViewController(alert, animated: true, completion: nil)

So from the error above. All you have to do to fix this issue is to revert your code. (git revert HEAD) then git pull and then redo your changes, then git pull again and was able to commit or merge with no errors.

To fix this, you must review your PHP.INI, and the mail services setup you have in your server.

But my best advice for you is to forget about the mail() function. It depends on PHP.INI settings, it's configuration is different depending on the platform (Linux or Windows), and it can't handle SMTP authentication, which is a big trouble in current days. Too much headache.

Use "PHP Mailer" instead (https://github.com/PHPMailer/PHPMailer), it's a PHP class available for free, and it can handle almost any SMTP server, internal or external, with or without authentication, it works exactly the same way on Linux and Windows, and it won't depend on PHP.INI settings. It comes with many examples, it's very powerful and easy to use.

I had a similar problem when trying to resolve host names using [system.net.dns]. If the IP wasn't resolved .Net threw a terminating error. To prevent the terminating error and still retain control of the output, I created a function using TRAP.

E.G.

Function Get-IP 
{PARAM   ([string]$HostName="")
PROCESS {TRAP 
             {"" ;continue} 
             [system.net.dns]::gethostaddresses($HostName)
        }
}

Even icfantv's answer to this question is already perfect, I still have more findings in my test.

As a server socket in listening status, if it only in listening status, and even it accepts request and getting data from the client side, but without any data sending action. We still could restart the server at once after it's stopped. But if any data sending action happens in the server side to the client, the same service(same port) restart will have this error: (Address already in use).

I think this is caused by the TCP/IP design principles. When the server send the data back to client, it must ensure the data sending succeed, in order to do this, the OS(Linux) need monitor the connection even the server application closed this socket. But I still believe kernel socket designer could improve this issue.

The shortest solution for the year 2020 (for those happy people who don't need to support IE)

Tested in Chrome, Firefox, Safari.

function onBeforeUnload(e) {
    if (thereAreUnsavedChanges()) {
        e.preventDefault();
        e.returnValue = '';
        return;
    }

    delete e['returnValue'];
}

window.addEventListener('beforeunload', onBeforeUnload);

Actually no one modern browser (Chrome, Firefox, Safari) displays the "return value" as a question to user. Instead they show their own confirmation text (it depends on browser). But we still need to return some (even empty) string to trigger that confirmation on Chrome.

You can simple go to app -> Providers -> AppServiceProvider.php

add two lines

use Illuminate\Support\Facades\URL;

URL::forceScheme('https');

as shows in the following codes:

use Illuminate\Support\Facades\URL;

class AppServiceProvider extends ServiceProvider
{
   public function boot()
    {
        URL::forceScheme('https');

       // any other codes here, does not matter.
    }

I think you want to set the response of the call to the URL 'compz.php?prodid=' + x + '&qbuys=' + y as value of the textbox right? If so, you have to do something like:

$.get('compz.php?prodid=' + x + '&qbuys=' + y, function(data) {
    $('#subtotal').val(data);
});

Reference: get()

You have two errors in your code:

• load() puts the HTML returned from the Ajax into the specified element:

  Load data from the server and place the returned HTML into the matched element.

  You cannot set the value of a textbox with that method.

• $(selector).load() returns the a jQuery object. By default an object is converted to [object Object] when treated as string.

Further clarification:

Assuming your URL returns 5.

If your HTML looks like:

<div id="foo"></div>

then the result of

$('#foo').load('/your/url');

will be

<div id="foo">5</div>

But in your code, you have an input element. Theoretically (it is not valid HTML and does not work as you noticed), an equivalent call would result in

<input id="foo">5</input>

But you actually need

<input id="foo" value="5" />

Therefore, you cannot use load(). You have to use another method, get the response and set it as value yourself.

Here is shortest way of doing it.

$userRecord = Model::where(['email'=>$email, 'password'=>$password])->first();

you can achive this by calling a function also

<div [style.width.px]="getCustomeWidth()"></div>

  getCustomeWidth() {
    //do what ever you want here
    return customeWidth;
  }

With all the solutions above even though you're hiding the code, you'll still get the [<matplotlib.lines.Line2D at 0x128514278>] crap above your figure which you probably don't want.

If you actually want to get rid of the input rather than just hiding it, I think the cleanest solution is to save your figures to disk in hidden cells, and then just including the images in Markdown cells using e.g. ![Caption](figure1.png).

I use Telegram.Bot and got the ID the following way:

1. Add the bot to the channel
2. Run the bot
3. Write something into the channel (eg: /authenticate or foo)

Telegram.Bot:

private static async Task Main()
{
    var botClient = new TelegramBotClient("key");
    botClient.OnUpdate += BotClientOnOnUpdate;
    Console.ReadKey();
}

private static async void BotClientOnOnUpdate(object? sender, UpdateEventArgs e)
{
    var id = e.Update.ChannelPost.Chat.Id;
    await botClient.SendTextMessageAsync(new ChatId(id), $"Hello World! Channel ID is {id}");
}

Plain API:

This translates to the getUpdates method in the plain API, which has an array of Update which then contains channel_post.chat.id

Bassed on the excellent answer of T.J. Crowder: (Off-topic: Avoid cluttering window)

This is an example of his idea:

Html

<!DOCTYPE html>
<html>
  <head>
    <script type="text/javascript" src="init.js"></script>
    <script type="text/javascript">
      MYLIBRARY.init(["firstValue", 2, "thirdValue"]);
    </script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Hello !</h1>
  </body>    
</html>

init.js (Based on this answer)

var MYLIBRARY = MYLIBRARY || (function(){
    var _args = {}; // private

    return {
        init : function(Args) {
            _args = Args;
            // some other initialising
        },
        helloWorld : function(i) {
            return _args[i];
        }
    };
}());

script.js

// Here you can use the values defined in the html as if it were a global variable
var a = "Hello World " + MYLIBRARY.helloWorld(2);

alert(a);

Here's the plnkr. Hope it help !

The jQuery documentation says that the datePicker needs to be attached to a SPAN or a DIV when it is not associated with an input box. You could do something like this:

<img src='someimage.gif' id="datepickerImage" />
<div id="datepicker"></div>

<script type="text/javascript">
 $(document).ready(function() {
    $("#datepicker").datepicker({
            changeMonth: true,
            changeYear: true,
    })
    .hide()
    .click(function() {
      $(this).hide();
    });

    $("#datepickerImage").click(function() {
       $("#datepicker").show(); 
    });
 });
</script>

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

There is an function, but it's extra: http://docs.jquery.com/Cookbook/wait

This little snippet allows you to wait:

$.fn.wait = function(time, type) {
    time = time || 1000;
    type = type || "fx";
    return this.queue(type, function() {
        var self = this;
        setTimeout(function() {
            $(self).dequeue();
        }, time);
    });
};

Swift 5. To see IF A DATE HAS PASSED:

let expiryDate = "2020-01-10" // Jan 10 2020

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

if Date() < dateFormatter.date(from: expiryDate) ?? Date() {
    print("Not Yet expiryDate")
} else {
    print("expiryDate has passed")
}

Be careful when checking directory only with option -d !
if variable $1 is empty the check will still be successfull. To be sure, check also that the variable is not empty.

#! /bin/bash

is_directory(){

    if [[ -d $1 ]] && [[ -n $1 ]] ; then
        return 0
    else
        return 1
    fi

}


#Test
if is_directory $1 ; then
    echo "Directory exist"
else
    echo "Directory does not exist!" 
fi

Thats because DataGridView looks for properties of containing objects. For string there is just one property - length. So, you need a wrapper for a string like this

public class StringValue
{
    public StringValue(string s)
    {
        _value = s;
    }
    public string Value { get { return _value; } set { _value = value; } }
    string _value;
}

Then bind List<StringValue> object to your grid. It works

You can run javascript code at any time. AFAIK it is executed at the moment the browser reaches the <script> tag where it is in. But you cannot access elements that are not loaded yet.

So if you need access to elements, you should wait until the DOM is loaded (this does not mean the whole page is loaded, including images and stuff. It's only the structure of the document, which is loaded much earlier, so you usually won't notice a delay), using the DOMContentLoaded event or functions like $.ready in jQuery.

The "best" way to share a Jupyter notebook is to simply to place it on GitHub (and view it directly) or some other public link and use the Jupyter Notebook Viewer. When privacy is more of an issue then there are alternatives but it's certainly more complex; there's no built-in way to do this in Jupyter alone, but a couple of options are:

Host your own nbviewer

GitHub and the Jupyter Notebook Veiwer both use the same tool to render .ipynb files into static HTML, this tool is nbviewer.

The installation instructions are more complex than I'm willing to go into here but if your company/team has a shared server that doesn't require password access then you could host the nbviewer on that server and direct it to load from your credentialed server. This will probably require some more advanced configuration than you're going to find in the docs.

Set up a deployment script

If you don't necessarily need live updating HTML then you could set up a script on your credentialed server that will simply use Jupyter's built-in export options to create the static HTML files and then send those to a more publicly accessible server.

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

You can use User Accounts by pressing Window+R, typing netplwiz and pressing OK as described here.

Our approach is simple, but it works! :)

When a user clicks our LogOut button, we simply open the login page (or any page) and close the page we are on...simulating opening in new browser window without any history to go back to.

<input id="btnLogout" onclick="logOut()" class="btn btn-sm btn-warning" value="Logout" type="button"/>
<script>
    function logOut() {
        window.close = function () { 
            window.open('Default.aspx', '_blank'); 
        };
    }
</script>

Use dt.days to obtain the days attribute as integers.

For eg:

In [14]: s = pd.Series(pd.timedelta_range(start='1 days', end='12 days', freq='3000T'))

In [15]: s
Out[15]: 
0    1 days 00:00:00
1    3 days 02:00:00
2    5 days 04:00:00
3    7 days 06:00:00
4    9 days 08:00:00
5   11 days 10:00:00
dtype: timedelta64[ns]

In [16]: s.dt.days
Out[16]: 
0     1
1     3
2     5
3     7
4     9
5    11
dtype: int64

More generally - You can use the .components property to access a reduced form of timedelta.

In [17]: s.dt.components
Out[17]: 
   days  hours  minutes  seconds  milliseconds  microseconds  nanoseconds
0     1      0        0        0             0             0            0
1     3      2        0        0             0             0            0
2     5      4        0        0             0             0            0
3     7      6        0        0             0             0            0
4     9      8        0        0             0             0            0
5    11     10        0        0             0             0            0

Now, to get the hours attribute:

In [23]: s.dt.components.hours
Out[23]: 
0     0
1     2
2     4
3     6
4     8
5    10
Name: hours, dtype: int64

With the launch of systemd, there's another scenario aswell. By default systemd will store core dumps in its journal, being accessible with the systemd-coredumpctl command. Defined in the core_pattern-file:

$ cat /proc/sys/kernel/core_pattern 
|/usr/lib/systemd/systemd-coredump %p %u %g %s %t %e

This behaviour can be disabled with a simple "hack":

$ ln -s /dev/null /etc/sysctl.d/50-coredump.conf
$ sysctl -w kernel.core_pattern=core      # or just reboot

As always, the size of core dumps has to be equal or higher than the size of the core that is being dumped, as done by for example ulimit -c unlimited.

git reset --soft HEAD^ Will keep the modified changes in your working tree.

git reset --hard HEAD^ WILL THROW AWAY THE CHANGES YOU MADE !!!

Just don't. Don't write code with code. Write a JSON object or a var somewhere but for the love of a sensible HTTP divide, don't write JavaScript functions or methods hardcoded with vars/properties provided by JSTL. Generating JSON is cool. It ends there or your UI dev hates you.

Imagine if you had to dig into JavaScript to find something that was setting parameters in the middle of a class that originated on the client-side. It's awful. Pass data back and forth. Handle the data. But don't try to generate actual code.

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

You almost got it - you need to set the scrollTop on body, not window:

$(function() {
   $('body').scrollTop(0);
});

EDIT:

Maybe you can add a blank anchor to the top of the page:

$(function() {
   $('<a name="top"/>').insertBefore($('body').children().eq(0));
   window.location.hash = 'top';
});

Try This

<EditText
  android:id="@+id/EditText1"
  android:text=""
  android:inputType="text|textNoSuggestions"
  android:textSize="18sp"
  android:layout_width="80dp"
  android:layout_height="43dp">
</EditText>

Try os.chdir

os.chdir(path)

        Change the current working directory to path. Availability: Unix, Windows.

If is a package then you can get the source for that with:

    select text from all_source where name = 'PADCAMPAIGN' 
    and type = 'PACKAGE BODY'
    order by line;

Oracle doesn't store the source for a sub-program separately, so you need to look through the package source for it.

Note: I've assumed you didn't use double-quotes when creating that package, but if you did , then use

    select text from all_source where name = 'pAdCampaign' 
    and type = 'PACKAGE BODY'
    order by line;

Parse int

parseInt(canvas.css("margin-left")); 

returns 0 for 0px

The tag set depends on the corpus that was used to train the tagger. The default tagger of nltk.pos_tag() uses the Penn Treebank Tag Set.

In NLTK 2, you could check which tagger is the default tagger as follows:

import nltk
nltk.tag._POS_TAGGER
>>> 'taggers/maxent_treebank_pos_tagger/english.pickle'

That means that it's a Maximum Entropy tagger trained on the Treebank corpus.

nltk.tag._POS_TAGGER does not exist anymore in NLTK 3 but the documentation states that the off-the-shelf tagger still uses the Penn Treebank tagset.

Rebase and Cherry-pick is the only way you can keep clean commit history. Avoid using merge and avoid creating merge conflict. If you are using gerrit set one project to Merge if necessary and one project to cherry-pick mode and try yourself.

Javadocs don't offer any special tools for external links, so you should just use standard html:

See <a href="http://groversmill.com/">Grover's Mill</a> for a history of the
Martian invasion.

or

@see <a href="http://groversmill.com/">Grover's Mill</a> for a history of 
the Martian invasion.

Don't use {@link ...} or {@linkplain ...} because these are for links to the javadocs of other classes and methods.

New Selenium libraries are now out, according to: https://github.com/SeleniumHQ/selenium/issues/2110

The download page http://www.seleniumhq.org/download/ seems not to be updated just yet, but by adding 1 to the minor version in the link, I could download the C# version: http://selenium-release.storage.googleapis.com/2.53/selenium-dotnet-2.53.1.zip

It works for me with Firefox 47.0.1.

As a side note, I was able build just the webdriver.xpi Firefox extension from the master branch in GitHub, by running ./go //javascript/firefox-driver:webdriver:run – which gave an error message but did build the build/javascript/firefox-driver/webdriver.xpi file, which I could rename (to avoid a name clash) and successfully load with the FirefoxProfile.AddExtension method. That was a reasonable workaround without having to rebuild the entire Selenium library.

this is working for me:

<td>
  <div class="avoid">
    Cell content.
  </div>
</td>
...
<style type="text/css">
  .avoid {
    page-break-inside: avoid !important;
    margin: 4px 0 4px 0;  /* to keep the page break from cutting too close to the text in the div */
  }
</style>

From this thread: avoid page break inside row of table

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

I have a listview which shows the Information about the all clients I am sorting the clients name using this custom comparator class. They are having some extra lerret apart from english letters which i am managing with this setStrength(Collator.SECONDARY)

 public class CustomNameComparator implements Comparator<ClientInfo> {
        @Override

    public int compare(ClientInfo o1, ClientInfo o2) { 

        Locale locale=Locale.getDefault();
        Collator collator = Collator.getInstance(locale);
        collator.setStrength(Collator.SECONDARY);
        return collator.compare(o1.title, o2.title);

    }
}


PRIMARY strength: Typically, this is used to denote differences between base characters (for example, "a" < "b"). It is the strongest difference. For example, dictionaries are divided into different sections by base character. 
SECONDARY strength: Accents in the characters are considered secondary differences (for example, "as" < "às" < "at"). Other differences between letters can also be considered secondary differences, depending on the language. A secondary difference is ignored when there is a primary difference anywhere in the strings. 
TERTIARY strength: Upper and lower case differences in characters are distinguished at tertiary strength (for example, "ao" < "Ao" < "aò"). In addition, a variant of a letter differs from the base form on the tertiary strength (such as "A" and "?"). Another example is the difference between large and small Kana. A tertiary difference is ignored when there is a primary or secondary difference anywhere in the strings. 
IDENTICAL strength: When all other strengths are equal, the IDENTICAL strength is used as a tiebreaker. The Unicode code point values of the NFD form of each string are compared, just in case there is no difference. For example, Hebrew cantellation marks are only distinguished at this strength. This strength should be used sparingly, as only code point value differences between two strings are an extremely rare occurrence. Using this strength substantially decreases the performance for both comparison and collation key generation APIs. This strength also increases the size of the collation key. 

**Here is a another way to make a rule base sorting if u need it just sharing**

/*      String rules="< å,Å< ä,Ä< a,A< b,B< c,C< d,D< é< e,E< f,F< g,G< h,H< ï< i,I"+"< j,J< k,K< l,L< m,M< n,N< ö,Ö< o,O< p,P< q,Q< r,R"+"< s,S< t,T< ü< u,U< v,V< w,W< x,X< y,Y< z,Z";
        RuleBasedCollator rbc = null;
        try {
            rbc = new RuleBasedCollator(rules);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        String myTitles[]={o1.title,o2.title};
        Collections.sort(Arrays.asList(myTitles), rbc);*/

Change your object.

var top_brands = [ 
  { key: 'Adidas', value: 100 }, 
  { key: 'Nike', value: 50 }
];

var $brand_options = $("#top-brands");

$.each(top_brands, function(brand) {
  $brand_options.append(
    $("<option />").val(brand.key).text(brand.key + " " + brand.value)
  );
});

As a rule of thumb:

• An object has data and structure.
• 'Adidas', 'Nike', 100 and 50 are data.
• Object keys are structure. Using data as the object key is semantically wrong. Avoid it.

There are no semantics in {Nike: 50}. What's "Nike"? What's 50?

{key: 'Nike', value: 50} is a little better, since now you can iterate an array of these objects and values are at predictable places. This makes it easy to write code that handles them.

Better still would be {vendor: 'Nike', itemsSold: 50}, because now values are not only at predictable places, they also have meaningful names. Technically that's the same thing as above, but now a person would also understand what the values are supposed to mean.

This issue happend when I use pylint_runner

So what I do is open .pylintrc file and add this

# List of members which are set dynamically and missed by pylint inference
# system, and so shouldn't trigger E1101 when accessed. Python regular
# expressions are accepted.
generated-members=objects

If you want to take into consideration the platform (x64, x86 etc) and the configuration (Debug or Release) it would be something like this:

xcopy "$(SolutionDir)\$(Platform)\$(Configuration)\$(TargetName).dll" "$(SolutionDir)TestDirectory\bin\$(Platform)\$(Configuration)\" /F /Y 

It could be the self-closing tag of link at the end, try:

<link href="https://fonts.googleapis.com/css?family=Bungee+Inline" rel="stylesheet"/> 

and in your main.css file try:

body,div {
  font-family: 'Bungee Inline', cursive;
}

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.

The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:

You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:

Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:

#toolbar=0&navpanes=0

So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.

string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

By encode, do you mean: Convert all applicable characters to HTML entities?

htmlspecialchars or htmlentities

You can also use strip_tags if you want to remove all HTML tags :

This topic is well covered already but I wanted to add something more specific : I wanted to be sure that a certain value would be mapped to that color (not to any color).

It is not complicated but as it took me some time, it might help others not lossing as much time as I did :)

import matplotlib
from matplotlib.colors import ListedColormap

# Let's design a dummy land use field
A = np.reshape([7,2,13,7,2,2], (2,3))
vals = np.unique(A)

# Let's also design our color mapping: 1s should be plotted in blue, 2s in red, etc...
col_dict={1:"blue",
          2:"red",
          13:"orange",
          7:"green"}

# We create a colormar from our list of colors
cm = ListedColormap([col_dict[x] for x in col_dict.keys()])

# Let's also define the description of each category : 1 (blue) is Sea; 2 (red) is burnt, etc... Order should be respected here ! Or using another dict maybe could help.
labels = np.array(["Sea","City","Sand","Forest"])
len_lab = len(labels)

# prepare normalizer
## Prepare bins for the normalizer
norm_bins = np.sort([*col_dict.keys()]) + 0.5
norm_bins = np.insert(norm_bins, 0, np.min(norm_bins) - 1.0)
print(norm_bins)
## Make normalizer and formatter
norm = matplotlib.colors.BoundaryNorm(norm_bins, len_lab, clip=True)
fmt = matplotlib.ticker.FuncFormatter(lambda x, pos: labels[norm(x)])

# Plot our figure
fig,ax = plt.subplots()
im = ax.imshow(A, cmap=cm, norm=norm)

diff = norm_bins[1:] - norm_bins[:-1]
tickz = norm_bins[:-1] + diff / 2
cb = fig.colorbar(im, format=fmt, ticks=tickz)
fig.savefig("example_landuse.png")
plt.show()

This answer is directed at further questions regarding Subversion subcommands options. For every available subcommand (i.e. add, log, status ...), you can simply add the --help option to display the complete list of available options you can use with your subcommand as well as examples on how to use them. The following snippet is taken directly from the svn log --help command output under the "examples" section :

Show the latest 5 log messages for the current working copy
directory and display paths changed in each commit:
  svn log -l 5 -v

The problem is you can't template a typedef, also there is no need to typedef structs in C++.

The following will do what you need

template <typename T> 
struct array { 
  size_t x; 
  T *ary; 
}; 

Just found out that with the Java NIO (java.nio.file.*) you can easily write:

List<String> lines=Files.readAllLines(Paths.get("/tmp/test.csv"), StandardCharsets.UTF_8);
for(String line:lines){
  System.out.println(line);
}

instead of dealing with FileInputStreams and BufferedReaders...

mysql>show processlist;

mysql> kill "number from first col";

Since API 21 there is an option set letter spacing. You can call method setLetterSpacing or set it in XML with attribute letterSpacing.
