2020 updates, overwriting Object.prototype

Object.prototype.map = function(func){
    for(const [k, v] of Object.entries(this)){
        func(k, v);
    }
    return this;
}

Object.prototype.reject = function(func){
    for(const [k, v] of Object.entries(this)){
        if(func(k, v)){
            delete this[k];
        }
    }
    return this;
}

Object.prototype.filter = function(func){
    let res = {};
    for(const [k, v] of Object.entries(this)){
        if(!func(k, v)){
            delete this[k];
        }

Targeting a specific commit

Remote (github)

When using github, note that you can also target a specific commit (for example, of a fork you've made and updated) by appending its commit hash to the end of its clone url. For example:

"dependencies": {
  "example": "https://github.com/owner_name/repo_name.git#9203e6166b343d7d8b3bb638775b41fe5de3524c"
}

Locally (filesystem)

Or you can target a git commit in your local file system if you use your project's .git directory, like so (on Windows; note the forward slashes):

"dependencies": {
  "example": "file://C:/Projects/my-project/.git#9203e6166b343d7d8b3bb638775b41fe5de3524c"
}

This is one way of testing library code you've committed locally but not yet pushed to the repo.

project link:

https://github.com/your_username/you_repo_name/settings

you will get a page like this, go to Collaborator and add collaborator

Your attempt at an athlete class seems to be dealing with a group of athletes, which is a design fault.

Define a class to represent a single athlete, with fields that represent the athlete's attributes:

public class Athlete {
    private final String name;
    private final String country;
    private List<Performance> performances = new ArrayList<Performance>();
    // other fields as required

    public Athlete (String name, String country) {
        this.name = name;
        this.country = country;
    }
    // getters omitted

    public List<Performance> getPerformances() {
        return performances;
    }

    public Performance perform(Dive dive) {
        // not sure what your intention is here, but something like this:
        Performance p = new Performance(dive, this);
        // add new performance to list
        performances.add(p);
        return p;
    }
}

Then your main method would use ti like this:

public class Assignment1 {
    public static void main(String[] args) {
        String[] name = {"Art", "Dan", "Jen"};
        String[] country = {"Canada", "Germant", "USA"};
        Dive[] dive = new Dive[]{new Dive("somersault"), new Dive("foo"), new Dive("bar")};
        for (int i = 0; i < name.length; i++) {
            Athlete athlete = new Athlete(name[i], country[i]);
            Performance performance = athlete.perform(dive[i]);   
            // do something with athlete and/or performance
        }
    }
}

Stumbled on this page as well, and then found out this is possible with just javascript (no plugins like ActiveX or Flash), but just in chrome:

https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3

Basically, they added support for a new attribute on the file input element "webkitdirectory". You can use it like this:

<input type="file" id="ctrl" webkitdirectory directory multiple/>

It allows you to select directories. The multiple attribute is a good fallback for browsers that support multiple file selection but not directory selection.

When you select a directory the files are available through the dom object for the control (document.getElementById('ctrl')), just like they are with the multiple attribute. The browsers adds all files in the selected directory to that list recursively.

You can already add the directory attribute as well in case this gets standardized at some point (couldn't find any info regarding that)

Multiple Attribute

var tag = "tag name";
createNode(tag, target, attribute);

createNode: function(tag, target, attribute){
    var tag = jQuery("<" + tag + ">");
    jQuery.each(attribute, function(i,v){
        tag.attr(v);
    });
    target.append(tag);
    tag.appendTo(target);
}
var attribute = [
    {"data-level": "3"},
];

You can set the variable 'fileencodings' in your .vimrc.

This is a list of character encodings considered when starting to edit an existing file. When a file is read, Vim tries to use the first mentioned character encoding. If an error is detected, the next one in the list is tried. When an encoding is found that works, 'fileencoding' is set to it. If all fail, 'fileencoding' is set to an empty string, which means the value of 'encoding' is used.

See :help filencodings

If you often work with e.g. cp1252, you can add it there:

set fileencodings=ucs-bom,utf-8,cp1252,default,latin9

Removing floats, and using inline-block may fix your problems:

 .pagination a {
-    display: block;
+    display: inline-block;
     width: 30px;
     height: 30px;
-    float: left;
     margin-left: 3px;
     background: url(/images/structure/pagination-button.png);
 }

(remove the lines starting with - and add the lines starting with +.)

.pagination {_x000D_
  text-align: center;_x000D_
}_x000D_
.pagination a {_x000D_
  + display: inline-block;_x000D_
  width: 30px;_x000D_
  height: 30px;_x000D_
  margin-left: 3px;_x000D_
  background: url(/images/structure/pagination-button.png);_x000D_
}_x000D_
.pagination a.last {_x000D_
  width: 90px;_x000D_
  background: url(/images/structure/pagination-button-last.png);_x000D_
}_x000D_
.pagination a.first {_x000D_
  width: 60px;_x000D_
  background: url(/images/structure/pagination-button-first.png);_x000D_
}

<div class='pagination'>_x000D_
  <a class='first' href='#'>First</a>_x000D_
  <a href='#'>1</a>_x000D_
  <a href='#'>2</a>_x000D_
  <a href='#'>3</a>_x000D_
  <a class='last' href='#'>Last</a>_x000D_
</div>_x000D_
<!-- end: .pagination -->

inline-block works cross-browser, even on IE6 as long as the element is originally an inline element.

Quote from quirksmode:

An inline block is placed inline (ie. on the same line as adjacent content), but it behaves as a block.

this often can effectively replace floats:

The real use of this value is when you want to give an inline element a width. In some circumstances some browsers don't allow a width on a real inline element, but if you switch to display: inline-block you are allowed to set a width.” ( http://www.quirksmode.org/css/display.html#inlineblock ).

From the W3C spec:

[inline-block] causes an element to generate an inline-level block container. The inside of an inline-block is formatted as a block box, and the element itself is formatted as an atomic inline-level box.

I might approach it like so (CSS and HTML):

html,_x000D_
body {_x000D_
  margin: 0px;_x000D_
}_x000D_
#logo {_x000D_
  position: absolute; /* Reposition logo from the natural layout */_x000D_
  left: 75px;_x000D_
  top: 0px;_x000D_
  width: 300px;_x000D_
  height: 200px;_x000D_
  z-index: 2;_x000D_
}_x000D_
#content {_x000D_
  margin-top: 100px; /* Provide buffer for logo */_x000D_
}_x000D_
#links {_x000D_
  height: 75px;_x000D_
  margin-left: 400px; /* Flush links (with a 25px "padding") right of logo */_x000D_
}

<div id="logo">_x000D_
  <img src="https://via.placeholder.com/200x100" />_x000D_
</div>_x000D_
<div id="content">_x000D_
  _x000D_
  <div id="links">dssdfsdfsdfsdf</div>_x000D_
</div>

There is one other option in regular expression, the search method

import re

string = 'Happy Birthday'
pattern = 'py'
print(re.search(pattern, string).span()) ## this prints starting and end indices
print(re.search(pattern, string).span()[0]) ## this does what you wanted

By the way, if you would like to find all the occurrence of a pattern, instead of just the first one, you can use finditer method

import re

string = 'i think that that that that student wrote there is not that right'
pattern = 'that'

print([match.start() for match in re.finditer(pattern, string)])

which will print all the starting positions of the matches.

To elaborate some more on this, adding

script-src 'self' http://somedomain 'unsafe-inline' 'unsafe-eval';

to the meta tag like so,

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; script-src 'self' https://somedomain.com/ 'unsafe-inline' 'unsafe-eval';  media-src *">

fixes the error.

This webpage have an explanation and a solution.

The solution is:

To fix this problem the behavior of the kernel has to be changed, so it will no longer overcommit the memory for application requests. Finally I have included those mentioned values into the /etc/sysctl.conf file, so they get automatically applied on start-up:

vm.overcommit_memory = 2

vm.overcommit_ratio = 80

Updated eclipse.ini file with key value property -Dosgi.requiredJavaVersion=1.7 (or) 1.8 whichever applicable. - it works for me.

How about the following:

    uint reverseMSBToLSB32ui(uint input)
    {
        uint output = 0x00000000;
        uint toANDVar = 0;
        int places = 0;

        for (int i = 1; i < 32; i++)
        {
            places = (32 - i);
            toANDVar = (uint)(1 << places);
            output |= (uint)(input & (toANDVar)) >> places;

        }


        return output;
    }

Small and easy (though, 32 bit only).

If you want a dictionary you can import from a file by name, and also that adds entries that are nicely sorted, and contains strings you want to preserve, you can try this:

data = {'A': 'a', 'B': 'b', }

with open('file.py','w') as file:
    file.write("dictionary_name = { \n")
    for k in sorted (data.keys()):
        file.write("'%s':'%s', \n" % (k, data[k]))
    file.write("}")

Then to import:

from file import dictionary_name

npm install -g webpack-dev-server will solve your issue

Yet another answer: Use parameter expansion on empty parameters:

# calls curl 4 times 
curl -s -w "\n" -X GET "http:{,,,}//www.google.com"

Tested on Centos 7 and MacOS.

We can use another way to edit files inside working containers (this won't work if container is stoped).

Logic is to:
-)copy file from container to host
-)edit file on host using its host editor
-)copy file back to container

We can do all this steps manualy, but i have written simple bash script to make this easy by one call.

/bin/dmcedit:

#!/bin/sh
set -e

CONTAINER=$1
FILEPATH=$2
BASE=$(basename $FILEPATH)
DIR=$(dirname $FILEPATH)
TMPDIR=/tmp/m_docker_$(date +%s)/

mkdir $TMPDIR
cd $TMPDIR
docker cp $CONTAINER:$FILEPATH ./$DIR
mcedit ./$FILEPATH
docker cp ./$FILEPATH $CONTAINER:$FILEPATH
rm -rf $TMPDIR

echo 'END'
exit 1;

Usage example:

dmcedit CONTAINERNAME /path/to/file/in/container

The script is very easy, but it's working fine for me.

Any suggestions are appreciated.

Thread-safe-code works as specified, even when entered simultaneously by different threads. This often means, that internal data-structures or operations that should run uninterrupted are protected against different modifications at the same time.

Exists = IsObject(CurrentDb.TableDefs(tablename))

Make sure that in case your image is not in the dom, and you get it from local directory or server, you should wait for the image to load and just after that to draw it on the canvas.

something like that:

function drawBgImg() {
    let bgImg = new Image();
    bgImg.src = '/images/1.jpg';
    bgImg.onload = () => {
        gCtx.drawImage(bgImg, 0, 0, gElCanvas.width, gElCanvas.height);
    }
}

There is an open source library called SVGInject that uses the onload attribute to trigger the injection. You can find the GitHub project at https://github.com/iconfu/svg-inject

Here is a minimal example using SVGInject:

<html>
  <head>
    <script src="svg-inject.min.js"></script>
  </head>
  <body>
    <img src="image.svg" onload="SVGInject(this)" />
  </body>
</html>

After the image is loaded the onload="SVGInject(this) will trigger the injection and the <img> element will be replaced by the contents of the SVG file provided in the src attribute.

It solves several issues with SVG injection:

1. SVGs can be hidden until injection has finished. This is important if a style is already applied during load time, which would otherwise cause a brief "unstyled content flash".

2. The <img> elements inject themselved automatically. If you add SVGs dynamically, you don't have to worry about calling the injection function again.

3. A random string is added to each ID in the SVG to avoid having the same ID multiple times in the document if an SVG is injected more than once.

SVGInject is plain Javascript and works with all browsers that support SVG.

Disclaimer: I am the co-author of SVGInject

Note that if variable is list of lists, some approaches would fail. For example:

v1 = [[range(3)] for x in range(4)]
v2 = v1[:3]+v1[4:] # this fails
v2

For the general case, use

removed_index = 1
v1 = [[range(3)] for x in range(4)]
v2 = [x for i,x in enumerate(v1) if x!=removed_index]
v2

As others have mentioned the Lint warning is because of the potential memory leak. You can avoid the Lint warning by passing a Handler.Callback when constructing Handler (i.e. you don't subclass Handler and there is no Handler non-static inner class):

Handler mIncomingHandler = new Handler(new Handler.Callback() {
    @Override
    public boolean handleMessage(Message msg) {
        // todo
        return true;
    }
});

As I understand it, this will not avoid the potential memory leak. Message objects hold a reference to the mIncomingHandler object which holds a reference the Handler.Callback object which holds a reference to the Service object. As long as there are messages in the Looper message queue, the Service will not be GC. However, it won't be a serious issue unless you have long delay messages in the message queue.

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

The problem is that .click only works for elements already on the page. You have to use something like on if you are wiring up future elements

$("#LangTable").on("click",".deletelanguage", function(){
  alert("success");
});

I think concat is a nice way to do this. If they are present it uses the name attributes of the Series as the columns (otherwise it simply numbers them):

In [1]: s1 = pd.Series([1, 2], index=['A', 'B'], name='s1')

In [2]: s2 = pd.Series([3, 4], index=['A', 'B'], name='s2')

In [3]: pd.concat([s1, s2], axis=1)
Out[3]:
   s1  s2
A   1   3
B   2   4

In [4]: pd.concat([s1, s2], axis=1).reset_index()
Out[4]:
  index  s1  s2
0     A   1   3
1     B   2   4

Note: This extends to more than 2 Series.

table-layout:fixed will resolve the expanding cell problem, but will create a new one. IE by default will hide the overflow but Mozilla will render it outside the box.

Another solution would be to use: overflow:hidden;width:?px

<table style="table-layout:fixed; width:100px">
 <tr>
   <td style="overflow:hidden; width:50px;">fearofthedarkihaveaconstantfearofadark</td>
   <td>
     test
   </td>
 </tr>
</table>

Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

ABSTRACT CLASSES AND ABSTARCT METHODS FULL DESCRIPTION GO THROUGH IT

abstract method do not have body.A well defined method can't be declared abstract.

A class which has abstract method must be declared as abstract.

Abstract class can't be instantiated.

Further to the answers above you can do this:

import React from 'react';

export default class Test extends React.Component {
  constructor(props) {
    super(props);
  }

  componentDidMount() {
    const s = document.createElement('script');
    s.type = 'text/javascript';
    s.async = true;
    s.innerHTML = "document.write('This is output by document.write()!')";
    this.instance.appendChild(s);
  }

  render() {
    return <div ref={el => (this.instance = el)} />;
  }
}

The div is bound to this and the script is injected into it.

Demo can be found on codesandbox.io

The href is a required attribute of an anchor element, so without it, you cannot expect all browsers to handle it equally. Anyway, I read somewhere in a comment that you only want the link to be underlined when hovering, and not otherwise. You can use the following to achieve this, and it will only apply to links with the hover-class:

<a class="hover" href="">click</a>

a.hover {
    text-decoration: none;
}

a.hover:hover {
    text-decoration:underline;
}

Stop this error you have to follow this simple steps

1. Open Visual Studio
2. Select option debug from the top
3. Select Options
4. In Option Select debugging under debugging select General
5. In General Select check box "Automatically close the console when debugging stop"
6. Save it

Then Run the code by using Shortcut key Ctrl+f5

**Other wise it still show error when you run it direct

In addition to the above configurations, I had to set deployment target to "Open Select Deployment Target Dialog", run once (choosing my device from the options listed), and from then on Android Studio was able to see my device even after changing the deployment setting back to "USB Device". My SWAG is that since Android Studio uses its own internal cache to find your device, it has to be initialized first.

This is because in line

graph(x**3+2*x-4, range(-10, 11))

x is not defined.

The easiest way is to pass the function you want to plot as a string and use eval to evaluate it as an expression.

So your code with minimal modifications will be

import numpy as np  
import matplotlib.pyplot as plt  
def graph(formula, x_range):  
    x = np.array(x_range)  
    y = eval(formula)
    plt.plot(x, y)  
    plt.show()

and you can call it as

graph('x**3+2*x-4', range(-10, 11))

If you need to find database objects (e.g. tables, columns, triggers) by name - have a look at the FREE Red-Gate tool called SQL Search which does this - it searches your entire database for any kind of string(s).

It's a great must-have tool for any DBA or database developer - did I already mention it's absolutely FREE to use for any kind of use??

I had this issue when working on a Java Project in Debian 10 with Tomcat as the application server.

The issue was that the application already had https defined as it's default protocol while I was using http to call the application in the browser. So when I try running the application I get this error in my log file:

org.apache.coyote.http11.AbstractHttp11Processor process
INFO: Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

I however tried using the https protocol in the browser but it didn't connect throwing the error:

Here's how I solved it:

You need a certificate to setup the https protocol for the application. I first had to create a keystore file for the application, more like a self-signed certificate for the https protocol:

sudo keytool -genkey -keyalg RSA -alias tomcat -keystore /usr/share/tomcat.keystore

Note: You need to have Java installed on the server to be able to do this. Java can be installed using sudo apt install default-jdk.

Next, I added a https Tomcat server connector for the application in the Tomcat server configuration file (/opt/tomcat/conf/server.xml):

sudo nano /opt/tomcat/conf/server.xml

Add the following to the configuration of the application. Notice that the keystore file location and password are specified. Also a port for the https protocol is defined, which is different from the port for the http protocol:

<Connector protocol="org.apache.coyote.http11.Http11Protocol"
           port="8443" maxThreads="200" scheme="https"
           secure="true" SSLEnabled="true"
           keystoreFile="/usr/share/tomcat.keystore"
           keystorePass="my-password"
           clientAuth="false" sslProtocol="TLS"
           URIEncoding="UTF-8"
           compression="force"
           compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"/>

So the full server configuration for the application looked liked this in the Tomcat server configuration file (/opt/tomcat/conf/server.xml):

<Service name="my-application">
  <Connector protocol="org.apache.coyote.http11.Http11Protocol"
             port="8443" maxThreads="200" scheme="https"
             secure="true" SSLEnabled="true"
             keystoreFile="/usr/share/tomcat.keystore"
             keystorePass="my-password"
             clientAuth="false" sslProtocol="TLS"
             URIEncoding="UTF-8"
             compression="force"
             compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"/>

  <Connector port="8009" protocol="HTTP/1.1"
             connectionTimeout="20000"
             redirectPort="8443" />

  <Engine name="my-application" defaultHost="localhost">
     <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>
    </Realm>

    <Host name="localhost"  appBase="webapps"
          unpackWARs="true" autoDeploy="true">

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
             prefix="localhost_access_log" suffix=".txt"
             pattern="%h %l %u %t &quot;%r&quot; %s %b" />

    </Host>
  </Engine>
</Service>

This time when I tried accessing the application from the browser using:

https://my-server-ip-address:https-port

In my case it was:

https:35.123.45.6:8443

it worked fine. Although, I had to accept a warning which added a security exception for the website since the certificate used is a self-signed one.

That's all.

I hope this helps

In Java there is nothing at language level similar to ref. In Java there is only passing by value semantic

For the sake of curiosity you can implement a ref-like semantic in Java simply wrapping your objects in a mutable class:

public class Ref<T> {

    private T value;

    public Ref(T value) {
        this.value = value;
    }

    public T get() {
        return value;
    }

    public void set(T anotherValue) {
        value = anotherValue;
    }

    @Override
    public String toString() {
        return value.toString();
    }

    @Override
    public boolean equals(Object obj) {
        return value.equals(obj);
    }

    @Override
    public int hashCode() {
        return value.hashCode();
    }
}

testcase:

public void changeRef(Ref<String> ref) {
    ref.set("bbb");
}

// ...
Ref<String> ref = new Ref<String>("aaa");
changeRef(ref);
System.out.println(ref); // prints "bbb"

Just define the variable as a variant, and make them equal:

Dim DirArray As Variant
DirArray = Range("a1:a5").Value

No need for the Array command.

        /// <summary>
    /// Returns a new conContractorEntity instance filled with the DataReader's current record data
    /// </summary>
    protected virtual conContractorEntity GetContractorFromReader(IDataReader reader)
    {
        return new conContractorEntity()
        {
            ConId = reader["conId"].ToString().Length > 0 ? int.Parse(reader["conId"].ToString()) : 0,
            ConEmail = reader["conEmail"].ToString(),
            ConCopyAdr = reader["conCopyAdr"].ToString().Length > 0 ? bool.Parse(reader["conCopyAdr"].ToString()) : true,
            ConCreateTime = reader["conCreateTime"].ToString().Length > 0 ? DateTime.Parse(reader["conCreateTime"].ToString()) : DateTime.MinValue
        };
    }

OR

            ConEmail = reader["conEmail"].ToString(),
            ConCopyAdr = GetValue<bool>(reader["conCopyAdr"], true),
            ConCreateTime = GetValue<DateTime>(reader["conCreateTime"])
        };
    }

With Git 2.25 (Q1 2020), you can modify it.
See "Git submodule url changed" and the new command

git submodule set-url [--] <path> <newurl>

Original answer (May 2009, ten years ago)

Actually, a patch has been submitted in April 2009 to clarify gitmodule role.

So now the gitmodule documentation does not yet include:

The .gitmodules file, located in the top-level directory of a git working tree, is a text file with a syntax matching the requirements -of linkgit:git-config1.
[NEW]:
As this file is managed by Git, it tracks the +records of a project's submodules.
Information stored in this file is used as a hint to prime the authoritative version of the record stored in the project configuration file.
User specific record changes (e.g. to account for differences in submodule URLs due to networking situations) should be made to the configuration file, while record changes to be propagated (e.g. +due to a relocation of the submodule source) should be made to this file.

That pretty much confirm Jim's answer.

If you follow this git submodule tutorial, you see you need a "git submodule init" to add the submodule repository URLs to .git/config.

"git submodule sync" has been added in August 2008 precisely to make that task easier when URL changes (especially if the number of submodules is important).
The associate script with that command is straightforward enough:

module_list "$@" |
while read mode sha1 stage path
do
    name=$(module_name "$path")
    url=$(git config -f .gitmodules --get submodule."$name".url)
    if test -e "$path"/.git
    then
    (
        unset GIT_DIR
        cd "$path"
        remote=$(get_default_remote)
        say "Synchronizing submodule url for '$name'"
        git config remote."$remote".url "$url"
    )
    fi
done

The goal remains: git config remote."$remote".url "$url"

If you get an error 1044 (42000) when you try to run SQL commands in MySQL (which installed along XAMPP server) cmd prompt, then here's the solution:

1. Close your MySQL command prompt.

2. Open your cmd prompt (from Start menu -> run -> cmd) which will show: C:\Users\User>_

3. Go to MySQL.exe by Typing the following commands:

C:\Users\User>cd\ C:\>cd xampp C:\xampp>cd mysql C:\xxampp\mysql>cd bin C:\xampp\mysql\bin>mysql -u root

1. Now try creating a new database by typing:

   mysql> create database employee;
   

   if it shows:

   Query OK, 1 row affected (0.00 sec)
   mysql>
   

   Then congrats ! You are good to go...

This kind of query should work - after rewriting with explicit JOIN syntax:

SELECT something
FROM   master      parent
JOIN   master      child ON child.parent_id = parent.id
LEFT   JOIN second parentdata ON parentdata.id = parent.secondary_id
LEFT   JOIN second childdata ON childdata.id = child.secondary_id
WHERE  parent.parent_id = 'rootID'

The tripping wire here is that an explicit JOIN binds before "old style" CROSS JOIN with comma (,). I quote the manual here:

In any case JOIN binds more tightly than the commas separating FROM-list items.

After rewriting the first, all joins are applied left-to-right (logically - Postgres is free to rearrange tables in the query plan otherwise) and it works.

Just to make my point, this would work, too:

SELECT something
FROM   master parent
LEFT   JOIN second parentdata ON parentdata.id = parent.secondary_id
,      master child
LEFT   JOIN second childdata ON childdata.id = child.secondary_id
WHERE  child.parent_id = parent.id
AND    parent.parent_id = 'rootID'

But explicit JOIN syntax is generally preferable, as your case illustrates once again.

And be aware that multiple (LEFT) JOIN can multiply rows:

• Two SQL LEFT JOINS produce incorrect result

Assuming a bit more memory usage is not a problem and if the first item of your tuple is hashable, you can create a dict out of your list of tuples and then looking up the value is as simple as looking up a key from the dict. Something like:

dct = dict(tuples)
val = dct.get(key) # None if item not found else the corresponding value

EDIT: To create a reverse mapping, use something like:

revDct = dict((val, key) for (key, val) in tuples)

You can also use now() in Postgres. The problem is you can't add/subtract integers from timestamp or timestamptz. You can either do as Mark Byers suggests and subtract an interval, or use the date type which does allow you to add/subtract integers

SELECT now()::date + 100 AS date1, current_date - 100 AS date2

How can I accomplish that?

Your example declares a TypeScript < 1.5 internal module, which is now called a namespace. The old module App {} syntax is now equivalent to namespace App {}. As a result, the following works:

// test.ts
export namespace App {
    export class SomeClass {
        getName(): string {
            return 'name';
        }
    }
}

// main.ts
import { App } from './test';
var a = new App.SomeClass();

That being said...

Try to avoid exporting namespaces and instead export modules (which were previously called external modules). If needs be you can use a namespace on import with the namespace import pattern like this:

// test.ts
export class SomeClass {
    getName(): string {
        return 'name';
    }
}

// main.ts
import * as App from './test'; // namespace import pattern
var a = new App.SomeClass();

<?php require("ckeditor/ckeditor.php"); ?>

 <script type="text/javascript" src="ckeditor/ckeditor.js"></script>
 <script type="text/javascript" src="somedirectory/ckeditor/ckeditor.js"></script>

<textarea class="ckeditor" name="editor1"></textarea>

BigDataCloud also has a nice API for this, also for nodejs users.

they have API for client - free. But also for backend, using API_KEY (free according to quota).

Their GitHub page.

the code looks like:

const client = require('@bigdatacloudapi/client')(API_KEY);

async foo() {
    ...
    const location: string = await client.getReverseGeocode({
          latitude:'32.101786566878445', 
          longitude: '34.858965073072056'
    });
}

In case you need to perform privileged tasks like changing permissions of folders you can perform those tasks as a root user and then create a non-privileged user and switch to it:

From <some-base-image:tag>

# Switch to root user
USER root # <--- Usually you won't be needed it - Depends on base image

# Run privileged command
RUN apt install <packages>
RUN apt <privileged command>

# Set user and group
ARG user=appuser
ARG group=appuser
ARG uid=1000
ARG gid=1000
RUN groupadd -g ${gid} ${group}
RUN useradd -u ${uid} -g ${group} -s /bin/sh -m ${user} # <--- the '-m' create a user home directory

# Switch to user
USER ${uid}:${gid}

# Run non-privileged command
RUN apt <non-privileged command>

Beware of adding an unwanted timezone to your results, especially if the date is going to be sent out via a Web API. Use UtcNow instead, to make it timezone-less.

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

There is no way to do what you say in C++ with plain arrays. The C++ solution for that is by using the STL library that gives you the std::vector.

You can use a vector in this way:

#include <vector>

std::vector< int > arr;

arr.push_back(1);
arr.push_back(2);
arr.push_back(3);

You can use extension methods to do the same thing with less code.

public enum AccountType
{
    Retailer = 1,
    Customer = 2,
    Manager = 3,
    Employee = 4
}

static class AccountTypeMethods
{
    public static bool IsRetailer(this AccountType ac)
    {
        return ac == AccountType.Retailer;
    }
}

And to use:

if (userProfile.AccountType.isRetailer())
{
    //your code
}

I would recommend to rename the AccountType to Account. It's not a name convention.

I like a combination of Gaurav's and user2550946's answer best, but would like to add two more aspects:

1. Don't use JAVA_OPTS, instead use CATALINA_OPTS. This will be used solely for starting tomcat, not for shutting it down. Typically you want more memory when starting tomcat, but the shutdown process (which just spins up, tells tomcat to shut down and then ends again) doesn't need any specifically tuned resources. In fact, shutdown can even fail if some ridiculous amount of memory is not available from the OS anymore.

2. On production systems, my recommentation is to claim the maximum allowed memory immediately. Because if you anticipate that the memory will be required sooner or later, you don't want to discover it not being available at 3am in the night - rather when you start up the server. Thus, set -Xmx and -Xms to the same value in production systems. (This makes my aspect 1 even more relevant)

Or, in one line, here's my recommendation:

set "CATALINA_OPTS=%CATALINA_OPTS% -Xms1024M -Xmx1024M"

Generally speaking, for boolean or bit data types, you would use 0 or 1 like so:

UPDATE tbl SET bitCol = 1 WHERE bitCol = 0

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

Normal mode: see other answers.

The Ex way:

• :t. will duplicate the line,
• :t 7 will copy it after line 7,
• :,+t0 will copy current and next line at the beginning of the file (,+ is a synonym for the range .,.+1),
• :1,t$ will copy lines from beginning till cursor position to the end (1, is a synonym for the range 1,.).

If you need to move instead of copying, use :m instead of :t.

This can be really powerful if you combine it with :g or :v:

• :v/foo/m$ will move all lines not matching the pattern “foo” to the end of the file.
• :+,$g/^\s*class\s\+\i\+/t. will copy all subsequent lines of the form class xxx right after the cursor.

Reference: :help range, :help :t, :help :g, :help :m and :help :v

Using jQuery in this case, the simplest form would be:

if ($(testString).length > 0)

If $(testString).length = 1, this means that there is one HTML tag inside textStging.

Python lists (which are not just arrays because their size can be changed on the fly) are normal Python objects and can be passed in to functions as any variable. The * syntax is used for unpacking lists, which is probably not something you want to do now.

Was facing a similar issue using IntelliJ and in case it may be helpful to someone else what fixed it for me was to change the Use classpath of module field, to have it as the one that shows the package name.

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

Giving admin rights or full control to my database install location solved my problem

Open cmd with "Run as administrator" and execute the command pip install mitmproxy. It will install it.

instead of ng-model you can use this code:

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

@Component({
  selector: 'my-app',
  template: `<input #box (keyup)="0">
    <p>{{box.value}}</p>`,
})
export class AppComponent  {}

inside your app.component.ts

Even in base Python you can do the computation in generic form

result = sum(x**2 for x in some_vector) ** 0.5

x ** 2 is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).

Using instead x ** 0.5 to take the square root doesn't do the exact same computations as math.sqrt as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.

I often use x ** 0.5 simply because I don't want to add math just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.

I don't know, it works fine for me. Exact commands:

import scipy, pylab
ax = pylab.subplot(111)
ax.scatter(scipy.randn(100), scipy.randn(100), c='b')
ax.scatter(scipy.randn(100), scipy.randn(100), c='r')
ax.figure.show()

COLLATE UTF8_GENERAL_CI will work as ignore-case. USE:

or

Generally, as long as your log4j.properties file is on the classpath, Log4j should just automatically pick it up at JVM startup.

I've tried to find a "fit to screen" property but there is no such.

But setting widget's "maximumSize" to a "some big number" ( like 2000 x 2000 ) will automatically fit the widget to the parent widget space.

You can use >> to print in another file.

echo "hello" >> logfile.txt

Here's a thread safe way of doing it:

// Foo.h
@interface Foo {
}

+(NSDictionary*) dictionary;

// Foo.m
+(NSDictionary*) dictionary
{
  static NSDictionary* fooDict = nil;

  static dispatch_once_t oncePredicate;

  dispatch_once(&oncePredicate, ^{
        // create dict
    });

  return fooDict;
}

These edits ensure that fooDict is only created once.

From Apple documentation: "dispatch_once - Executes a block object once and only once for the lifetime of an application."

You need to define an AbstractBinder and register it in your JAX-RS application. The binder specifies how the dependency injection should create your classes.

public class MyApplicationBinder extends AbstractBinder {
    @Override
    protected void configure() {
        bind(MyService.class).to(MyService.class);
    }
}

When @Inject is detected on a parameter or field of type MyService.class it is instantiated using the class MyService. To use this binder, it need to be registered with the JAX-RS application. In your web.xml, define a JAX-RS application like this:

<servlet>
  <servlet-name>MyApplication</servlet-name>
  <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>com.mypackage.MyApplication</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>MyApplication</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

Implement the MyApplication class (specified above in the init-param).

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        register(new MyApplicationBinder());
        packages(true, "com.mypackage.rest");
    }
}

The binder specifying dependency injection is registered in the constructor of the class, and we also tell the application where to find the REST resources (in your case, MyResource) using the packages() method call.

Crockford has done a lot to popularize good JavaScript techniques. His opinionated stance on key elements of the language have sparked many useful discussions. That said, there are far too many people that take each proclamation of "bad" or "harmful" as gospel, refusing to look beyond one man's opinion. It can be a bit frustrating at times.

Use of the functionality provided by the new keyword has several advantages over building each object from scratch:

1. Prototype inheritance. While often looked at with a mix of suspicion and derision by those accustomed to class-based OO languages, JavaScript's native inheritance technique is a simple and surprisingly effective means of code re-use. And the new keyword is the canonical (and only available cross-platform) means of using it.
2. Performance. This is a side-effect of #1: if I want to add 10 methods to every object I create, I could just write a creation function that manually assigns each method to each new object... Or, I could assign them to the creation function's prototype and use new to stamp out new objects. Not only is this faster (no code needed for each and every method on the prototype), it avoids ballooning each object with separate properties for each method. On slower machines (or especially, slower JS interpreters) when many objects are being created this can mean a significant savings in time and memory.

And yes, new has one crucial disadvantage, ably described by other answers: if you forget to use it, your code will break without warning. Fortunately, that disadvantage is easily mitigated - simply add a bit of code to the function itself:

function foo()
{
   // if user accidentally omits the new keyword, this will 
   // silently correct the problem...
   if ( !(this instanceof foo) )
      return new foo();

   // constructor logic follows...
}

Now you can have the advantages of new without having to worry about problems caused by accidentally misuse. You could even add an assertion to the check if the thought of broken code silently working bothers you. Or, as some commented, use the check to introduce a runtime exception:

if ( !(this instanceof arguments.callee) ) 
   throw new Error("Constructor called as a function");

(Note that this snippet is able to avoid hard-coding the constructor function name, as unlike the previous example it has no need to actually instantiate the object - therefore, it can be copied into each target function without modification.)

John Resig goes into detail on this technique in his Simple "Class" Instantiation post, as well as including a means of building this behavior into your "classes" by default. Definitely worth a read... as is his upcoming book, Secrets of the JavaScript Ninja, which finds hidden gold in this and many other "harmful" features of the JavaScript language (the chapter on with is especially enlightening for those of us who initially dismissed this much-maligned feature as a gimmick).

None of the above answers worked for me but I finally found what my issue was. Hopefully this will help someone down the line.

First run IIS Express from command prompt to validate that the site can or cannot be run

https://docs.microsoft.com/en-us/iis/extensions/using-iis-express/running-iis-express-from-the-command-line

Im my case, i got an error saying that C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\web.config had malformed xml on line 14. Looking at that line in the file it just said null null null null null etc.

The fix for me was to replace the web.config file with one from my coworkers. IMPORTANT you must get the file from someone running the same version ie if you are VS2015 get a copy from someone running VS2015. If you get it from someone running a different version you will see an error saying it could not load an assembly from the manifest.

Hopefully this helps someone that has tried all the suggestions above. I think the cause of this for me was updating from trial mode and adding a product key within VS2017

You can use this:

return Content(HttpStatusCode.BadRequest, "Any object");

Since the original question was about the SerializableAttribute, it should be noted that this attribute only applies when using the BinaryFormatter or SoapFormatter.

It is a bit confusing, unless you really pay attention to the details, as to when to use it and what its actual purpose is.

It has NOTHING to do with XML or JSON serialization.

Used with the SerializableAttribute are the ISerializable Interface and SerializationInfo Class. These are also only used with the BinaryFormatter or SoapFormatter.

Unless you intend to serialize your class using Binary or Soap, do not bother marking your class as [Serializable]. XML and JSON serializers are not even aware of its existence.

Please check this jsFiddle. (The code is basically the same you posted but I use an element instead of the window to bind the scroll events).

As far as I can see, there is no problem with the code you posted. The error you mentioned normally occurs when you create a loop of changes over a property. For example, like when you watch for changes on a certain property and then change the value of that property on the listener:

$scope.$watch('users', function(value) {
  $scope.users = [];
});

This will result on an error message:

Uncaught Error: 10 $digest() iterations reached. Aborting!
Watchers fired in the last 5 iterations: ...

Make sure that your code doesn't have this kind of situations.

update:

This is your problem:

<div ng-init="user.score=user.id+1"> 

You shouldn't change objects/models during the render or otherwise, it will force a new render (and consequently a loop, which causes the 'Error: 10 $digest() iterations reached. Aborting!').

If you want to update the model, do it on the Controller or on a Directive, never on the view. angularjs documentation recommends not to use the ng-init exactly to avoid these kinds of situations:

Use ngInit directive in templates (for toy/example apps only, not recommended for real applications)

Here's a jsFiddle with a working example.

See code below

ArrayList<String> a = new ArrayList<>(Arrays.asList(strings));
a.remove(i);
strings = new String[a.size()];
a.toArray(strings);

Case 1 should have worked. I don't see anything wrong. There may be some other problems. I would suggest a clean build.

What you are doing is pass by value not pass by reference. Because you are sending the value of a variable 'p' to the function 'f' (in main as f(p);)

The same program in C with pass by reference will look like,(!!!this program gives 2 errors as pass by reference is not supported in C)

#include <stdio.h>

void f(int &j) {    //j is reference variable to i same as int &j = i
  j++;
}

int main() {
  int i = 20;
  f(i);
  printf("i = %d\n", i);

  return 0;
}

Output:-

3:12: error: expected ';', ',' or ')' before '&' token
             void f(int &j);
                        ^
9:3:  warning: implicit declaration of function 'f'
               f(a);
               ^

As of Room 1.1.0 you can use clearAllTables() which:

Deletes all rows from all the tables that are registered to this database as entities().

To expand on previous answers, a function to do this could work like this (changing the time and interval formats however you like them according to this for function.date, and this for DateInterval):

(I've also written an alternate form of the below function here.)

// Return adjusted time.

function addMinutesToTime( $time, $plusMinutes ) {

    $time = DateTime::createFromFormat( 'g:i:s', $time );
    $time->add( new DateInterval( 'PT' . ( (integer) $plusMinutes ) . 'M' ) );
    $newTime = $time->format( 'g:i:s' );

    return $newTime;
}

$adjustedTime = addMinutesToTime( '9:15:00', 15 );

echo '<h1>Adjusted Time: ' . $adjustedTime . '</h1>' . PHP_EOL . PHP_EOL;

Use pseudo element:

.button {_x000D_
    background: #333;_x000D_
    color: #fff;_x000D_
    float: left;_x000D_
    padding: 20px;_x000D_
    margin: 20px;_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.button::after {_x000D_
    content: '';_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    right: 0;_x000D_
    bottom: 0;_x000D_
    left: 0;_x000D_
    border: 5px solid #f00;_x000D_
}

<div class='button'>Hello</div>

Using ::after you are styling the virtual last child of the selected element. content property creates an anonymous replaced element.

We are containing the pseudo element using absolute position relative to the parent. Then you have freedom to have whatever custom background and/or border in the background of your main element.

This approach does not affect placement of the contents of the main element, which is different from using box-sizing: border-box;.

Consider this example:

.parent {_x000D_
    width: 200px;_x000D_
}_x000D_
_x000D_
.button {_x000D_
    background: #333;_x000D_
    color: #fff;_x000D_
    padding: 20px;_x000D_
    border: 5px solid #f00;_x000D_
    border-left-width: 20px;_x000D_
    box-sizing: border-box;_x000D_
}

<div class='parent'>_x000D_
    <div class='button'>Hello</div>_x000D_
</div>

Here .button width is constrained using the parent element. Setting the border-left-width adjusts the content-box size and thus the position of the text.

.parent {_x000D_
    width: 200px;_x000D_
}_x000D_
_x000D_
.button {_x000D_
    background: #333;_x000D_
    color: #fff;_x000D_
    padding: 20px;_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.button::after {_x000D_
    content: '';_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    right: 0;_x000D_
    bottom: 0;_x000D_
    left: 0;_x000D_
    border: 5px solid #f00;_x000D_
    border-left-width: 20px;_x000D_
}

<div class='parent'>_x000D_
    <div class='button'>Hello</div>_x000D_
</div>

Using the pseudo-element approach does not affect the content-box size.

Depending on the application, approach using a pseudo-element might or might not be a desirable behaviour.

As others already wrote, a timer is the best option in the scenario you described.

Depending on your exact requirements, checking the current time every minute may not be necessary. If you do not need to perform the action exactly at midnight, but just within one hour after midnight, you can go for Martin's approach of only checking if the date has changed.

If the reason you want to perform your action at midnight is that you expect a low workload on your computer, better take care: The same assumption is often made by others, and suddenly you have 100 cleanup actions kicking off between 0:00 and 0:01 a.m.

In that case you should consider starting your cleanup at a different time. I usually do those things not at clock hour, but at half hours (1.30 a.m. being my personal preference)

The single " | " operator will evaluate both sides of the expression.

    if (ActionsLogWriter.Close | ErrorDumpWriter.Close == true)
{
    // Do stuff here
}

The double operator " || " will only evaluate the left side if the expression returns true.

    if (ActionsLogWriter.Close || ErrorDumpWriter.Close == true)
{
    // Do stuff here
}

C# has many similarities to C++ but their still are differences between the two languages ;)

I had virtual env site package problem and this helped me, maybe it will help you too

unset is the command you're looking for.

unset GNUPLOT_DRIVER_DIR

If you use df.replace([None], np.nan, inplace=True), this changed all datetime objects with missing data to object dtypes. So now you may have broken queries unless you change them back to datetime which can be taxing depending on the size of your data.

If you want to use this method, you can first identify the object dtype fields in your df and then replace the None:

obj_columns = list(df.select_dtypes(include=['object']).columns.values)
df[obj_columns] = df[obj_columns].replace([None], np.nan)

On Windows 7 I solved this by going into my environment settings (try this link for how) and adding user variables http_proxy and https_proxy with my proxy details.

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

This is the logger class that I use. The private Log() method has EventLog.WriteEntry() in it, which is how you actually write to the event log. I'm including all of this code here because it's handy. In addition to logging, this class will also make sure the message isn't too long to write to the event log (it will truncate the message). If the message was too long, you'd get an exception. The caller can also specify the source. If the caller doesn't, this class will get the source. Hope it helps.

By the way, you can get an ObjectDumper from the web. I didn't want to post all that here. I got mine from here: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Samples\1033\CSharpSamples.zip\LinqSamples\ObjectDumper

This problem looked familiar so I thought I'd see if I could replicate from the limited amount of information.

A quick search turned up an entry in James Bennett's blog here which mentions that when working with the UserProfile to extend the User model a common mistake in settings.py can cause Django to throw this error.

To quote the blog entry:

The value of the setting is not "appname.models.modelname", it's just "appname.modelname". The reason is that Django is not using this to do a direct import; instead, it's using an internal model-loading function which only wants the name of the app and the name of the model. Trying to do things like "appname.models.modelname" or "projectname.appname.models.modelname" in the AUTH_PROFILE_MODULE setting will cause Django to blow up with the dreaded "too many values to unpack" error, so make sure you've put "appname.modelname", and nothing else, in the value of AUTH_PROFILE_MODULE.

If the OP had copied more of the traceback I would expect to see something like the one below which I was able to duplicate by adding "models" to my AUTH_PROFILE_MODULE setting.

TemplateSyntaxError at /

    app_label, model_name = settings.AUTH_PROFILE_MODULE.split('.')
ValueError: too many values to unpack

This I think is one of the few cases where Django still has a bit of import magic that tends to cause confusion when a small error doesn't throw the expected exception.

You can see at the end of the traceback that I posted how using anything other than the form "appname.modelname" for the AUTH_PROFILE_MODULE would cause the line "app_label, model_name = settings.AUTH_PROFILE_MODULE.split('.')" to throw the "too many values to unpack" error.

I'm 99% sure that this was the original problem encountered here.

I have an alternative solution for you. You could create a hidden worksheet to maintain the old values for your range of interest.

Private Sub Workbook_Open()

Dim hiddenSheet As Worksheet

Set hiddenSheet = Me.Worksheets.Add
hiddenSheet.Visible = xlSheetVeryHidden
hiddenSheet.Name = "HiddenSheet"

'Change Sheet1 to whatever sheet you're working with
Sheet1.UsedRange.Copy ThisWorkbook.Worksheets("HiddenSheet").Range(Sheet1.UsedRange.Address)

End Sub

Delete it when the workbook is closed...

Private Sub Workbook_BeforeClose(Cancel As Boolean)

Application.DisplayAlerts = False
Me.Worksheets("HiddenSheet").Delete
Application.DisplayAlerts = True

End Sub

And modify your Worksheet_Change event like so...

For Each cell In Target

    If Not (Intersect(cell, Range("cell_of_interest")) Is Nothing) Then
        new_value = cell.Value
        ' here's your "old" value...
        old_value = ThisWorkbook.Worksheets("HiddenSheet").Range(cell.Address).Value
        Call DoFoo(old_value, new_value)
    End If

Next cell

' Update your "old" values...
ThisWorkbook.Worksheets("HiddenSheet").UsedRange.Clear
Me.UsedRange.Copy ThisWorkbook.Worksheets("HiddenSheet").Range(Me.UsedRange.Address)

If merging branch A into branch B reports "Already up to date", reverse is not always true. It is true only if branch B is descendant of branch A, otherwise branch B simply can have changes that aren't in A.

Example:

1. You create branches A and B off master
2. You make some changes in master and merge these changes only into branch B (not updating or forgetting to update branch A).
3. You make some changes in branch A and merge A to B.

At this point merging A to B reports "Already up to date" but the branches are different because branch B has updates from master while branch A does not.

We can get different return value from http_response_code via the two different environment:

1. Web Server Environment
2. CLI environment

At the web server environment, return previous response code if you provided a response code or when you do not provide any response code then it will be print the current value. Default value is 200 (OK).

At CLI Environment, true will be return if you provided a response code and false if you do not provide any response_code.

Example of Web Server Environment of Response_code's return value:

var_dump(http_respone_code(500)); // int(200)
var_dump(http_response_code()); // int(500)

Example of CLI Environment of Response_code's return value:

var_dump(http_response_code()); // bool(false)
var_dump(http_response_code(501)); // bool(true)
var_dump(http_response_code()); // int(501)

in your code add:

System.getProperty("WSNSHELL_HOME")

Modify or add value property from maven command:

mvn clean test -DargLine=-DWSNSHELL_HOME=yourvalue

If you want to run it in Eclipse, add VM arguments in your Debug/Run configurations

• Go to Run -> Run configurations
• Select Tab Arguments
• Add in section VM Arguments

-DWSNSHELL_HOME=yourvalue

you don't need to modify the POM

In addition to setting the registry entry for AuthServerWhitelist you should also set AuthSchemes: "ntlm,negotiate" (or just "ntlm" as appropriate for your situation). Using the above templates the policy for that will be "Supported authentication schemes"

You need to add query.addEntity(SwitcherServiceSource.class) before calling the .list() on query.

git checkout has the --ours option to check out the version of the file that you had locally (as opposed to --theirs, which is the version that you pulled in). You can pass . to git checkout to tell it to check out everything in the tree. Then you need to mark the conflicts as resolved, which you can do with git add, and commit your work once done:

git checkout --ours .  # checkout our local version of all files
git add -u             # mark all conflicted files as merged
git commit             # commit the merge

Note the . in the git checkout command. That's very important, and easy to miss. git checkout has two modes; one in which it switches branches, and one in which it checks files out of the index into the working copy (sometimes pulling them into the index from another revision first). The way it distinguishes is by whether you've passed a filename in; if you haven't passed in a filename, it tries switching branches (though if you don't pass in a branch either, it will just try checking out the current branch again), but it refuses to do so if there are modified files that that would effect. So, if you want a behavior that will overwrite existing files, you need to pass in . or a filename in order to get the second behavior from git checkout.

It's also a good habit to have, when passing in a filename, to offset it with --, such as git checkout --ours -- <filename>. If you don't do this, and the filename happens to match the name of a branch or tag, Git will think that you want to check that revision out, instead of checking that filename out, and so use the first form of the checkout command.

I'll expand a bit on how conflicts and merging work in Git. When you merge in someone else's code (which also happens during a pull; a pull is essentially a fetch followed by a merge), there are few possible situations.

The simplest is that you're on the same revision. In this case, you're "already up to date", and nothing happens.

Another possibility is that their revision is simply a descendent of yours, in which case you will by default have a "fast-forward merge", in which your HEAD is just updated to their commit, with no merging happening (this can be disabled if you really want to record a merge, using --no-ff).

Then you get into the situations in which you actually need to merge two revisions. In this case, there are two possible outcomes. One is that the merge happens cleanly; all of the changes are in different files, or are in the same files but far enough apart that both sets of changes can be applied without problems. By default, when a clean merge happens, it is automatically committed, though you can disable this with --no-commit if you need to edit it beforehand (for instance, if you rename function foo to bar, and someone else adds new code that calls foo, it will merge cleanly, but produce a broken tree, so you may want to clean that up as part of the merge commit in order to avoid having any broken commits).

The final possibility is that there's a real merge, and there are conflicts. In this case, Git will do as much of the merge as it can, and produce files with conflict markers (<<<<<<<, =======, and >>>>>>>) in your working copy. In the index (also known as the "staging area"; the place where files are stored by git add before committing them), you will have 3 versions of each file with conflicts; there is the original version of the file from the ancestor of the two branches you are merging, the version from HEAD (your side of the merge), and the version from the remote branch.

In order to resolve the conflict, you can either edit the file that is in your working copy, removing the conflict markers and fixing the code up so that it works. Or, you can check out the version from one or the other sides of the merge, using git checkout --ours or git checkout --theirs. Once you have put the file into the state you want it, you indicate that you are done merging the file and it is ready to commit using git add, and then you can commit the merge with git commit.

You can escape by doubling the quotes

g="abcd """ & a & """"

or write an explicit chr() call

g="abcd " & chr(34) & a & chr(34)

It seems to be a cast exception. Can you try converting your result to a list i.e. elem.findElements(xx).toList ?

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

C:\Users\Max\AppData\Local\Android\sdk\

The location I found it in for Windows 8.1. I think the default SDK folder. AppData is a hidden folder, so you will not locate it unless you type it in once you get into your C:\Users\ folder.

In Xcode 8.0 you can simply do it by changing insets in size inspector.

Select the UIButton -> Attributes Inspector -> go to size inspector and modify the content, image and title insets.

And if you want to change image on right side you can simply change the semantic property to Force Right-to-left in Attribute inspector .

Squashing the first and second commit would result in the first commit being rewritten. If you have more than one branch that is based off the first commit, you'd cut off that branch.

Consider the following example:

a---b---HEAD
 \
  \
   '---d

Squashing a and b into a new commit "ab" would result in two distinct trees which in most cases is not desirable since git-merge and git-rebase will no longer work across the two branches.

ab---HEAD

a---d

If you really want this, it can be done. Have a look at git-filter-branch for a powerful (and dangerous) tool for history rewriting.

<< is the left-shift operator, as it is in many other languages.

Here RAM_DEPTH will be 1 left-shifted by 8 bits, which is equivalent to 2^8, or 256.

At some point I read a reasonably convincing argument on Perlmonks that testing the type of a scalar with ref or reftype is a bad idea. I don't recall who put the idea forward, or the link. Sorry.

The point was that in Perl there are many mechanisms that make it possible to make a given scalar act like just about anything you want. If you tie a filehandle so that it acts like a hash, the testing with reftype will tell you that you have a filehanle. It won't tell you that you need to use it like a hash.

So, the argument went, it is better to use duck typing to find out what a variable is.

Instead of:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;
    if( $type eq 'HASH' ) {
        $result = $var->{foo};
    }
    elsif( $type eq 'ARRAY' ) {
        $result = $var->[3];
    }
    else {
        $result = 'foo';
    }

    return $result;
}

You should do something like this:

sub foo {
    my $var = shift;
    my $type = reftype $var;

    my $result;

    eval {
        $result = $var->{foo};
        1; # guarantee a true result if code works.
    }
    or eval { 
        $result = $var->[3];
        1;
    }
    or do {
        $result = 'foo';
    }

    return $result;
}

For the most part I don't actually do this, but in some cases I have. I'm still making my mind up as to when this approach is appropriate. I thought I'd throw the concept out for further discussion. I'd love to see comments.

Update

I realized I should put forward my thoughts on this approach.

This method has the advantage of handling anything you throw at it.

It has the disadvantage of being cumbersome, and somewhat strange. Stumbling upon this in some code would make me issue a big fat 'WTF'.

I like the idea of testing whether a scalar acts like a hash-ref, rather that whether it is a hash ref.

I don't like this implementation.

DATABASE_URL=postgres://{user}:{password}@{hostname}:{port}/{database-name}

but Long can not exceed the maximum :)

I know the question specifies Excel, but since the same question for Access got marked as duplicate, so I will post my answer here. The principle is simple: open a new Access application, then open a form with a timer inside that application, send the function/sub you want to execute to that form, execute the task if the timer hits, and quit the application once execution has finished. This allows the VBA to work with tables and queries from your database. Note: it will throw errors if you've exclusively locked the database.

This is all VBA (as opposed to other answers)

The function that runs a sub/function asynchronously

Public Sub RunFunctionAsync(FunctionName As String)
    Dim A As Access.Application
    Set A = New Access.Application
    A.OpenCurrentDatabase Application.CurrentProject.FullName
    A.DoCmd.OpenForm "MultithreadingEngine"
    With A.Forms("MultiThreadingEngine")
        .TimerInterval = 10
        .AddToTaskCollection (FunctionName)
    End With
End Sub

The module of the form required to achieve this

(form name = MultiThreadingEngine, doesn't have any controls or properties set)

Public TaskCollection As Collection

Public Sub AddToTaskCollection(str As String)
    If TaskCollection Is Nothing Then
        Set TaskCollection = New Collection
    End If
    TaskCollection.Add str
End Sub
Private Sub Form_Timer()
    If Not TaskCollection Is Nothing Then
        If TaskCollection.Count <> 0 Then
            Dim CollectionItem As Variant
            For Each CollectionItem In TaskCollection
                Run CollectionItem
            Next CollectionItem
        End If
    End If
    Application.Quit
End Sub

Implementing support for parameters should be easy enough, returning values is difficult, however.

There's at least 7 different ways to test if a number is odd or even. But, if you read through these benchmarks, you'll find that as TGH mentioned above, the modulus operation is the fastest:

if (x % 2 == 0)
               //even number
        else
               //odd number

Here are a few other methods (from the website) :

//bitwise operation
if ((x & 1) == 0)
       //even number
else
      //odd number

//bit shifting
if (((x >> 1) << 1) == x)
       //even number
else
       //odd number

//using native library
System.Math.DivRem((long)x, (long)2, out outvalue);
if ( outvalue == 0)
       //even number
else
       //odd number

Variant for C++:

#include <regex>  // Required include

...

// Source string    
std::wstring srcStr = L"String with GIUD: {4d36e96e-e325-11ce-bfc1-08002be10318} any text";

// Regex and match
std::wsmatch match;
std::wregex rx(L"(\\{[A-F0-9]{8}-[A-F0-9]{4}-[A-F0-9]{4}-[A-F0-9]{4}-[A-F0-9]{12}\\})", std::regex_constants::icase);

// Search
std::regex_search(srcStr, match, rx);

// Result
std::wstring strGUID       = match[1];

This one is simplier :)

dataview dataview1; 
this.dataview1= dataset.tables[0].defaultview;
this.dataview1.sort = "[ColumnName] ASC, [ColumnName] DESC";
this.datagridview.datasource = dataview1;

Although this is a pretty old question I must say it is touching exactly the knowledge I was missing during my first steps in R - i.e. how to express data in my hand as an object in R or how to select from existing objects. It is not easy for an R novice to think "in an R box" from the very beginning.

So I myself started to use crutches below which helped me a lot to find out what object to use for what data, and basically to imagine real-world usage.

Though I not giving exact answers to the question the short text below might help the reader who just started with R and is asking similar questions.

• Atomic vector ... I called that "sequence" for myself, no direction, just sequence of same types. [ subsets.
• Vector ... the sequence with one direction from 2D, [ subsets.
• Matrix ... bunch of vectors with the same length forming rows or columns, [ subsets by rows and columns, or by sequence.
• Arrays ... layered matrices forming 3D
• Dataframe ... a 2D table like in excel, where I can sort, add or remove rows or columns or make arit. operations with them, only after some time I truly recognized that data frame is a clever implementation of list where I can subset using [ by rows and columns, but even using [[.
• List ... to help myself I thought about the list as of tree structure where [i] selects and returns whole branches and [[i]] returns item from the branch. And because it is tree like structure, you can even use an index sequence to address every single leaf on a very complex list using its [[index_vector]]. Lists can be simple or very complex and can mix together various types of objects into one.

So for lists you can end up with more ways how to select a leaf depending on situation like in the following example.

l <- list("aaa",5,list(1:3),LETTERS[1:4],matrix(1:9,3,3))
l[[c(5,4)]] # selects 4 from matrix using [[index_vector]] in list
l[[5]][4] # selects 4 from matrix using sequential index in matrix
l[[5]][1,2] # selects 4 from matrix using row and column in matrix

This way of thinking helped me a lot.

Actual Swift 3 Answer

This is the ONLY function you need. You do not need CanEdit or CommitEditingStyle functions for custom actions.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let action1 = UITableViewRowAction(style: .default, title: "Action1", handler: {
        (action, indexPath) in
        print("Action1")
    })
    action1.backgroundColor = UIColor.lightGray
    let action2 = UITableViewRowAction(style: .default, title: "Action2", handler: {
        (action, indexPath) in
        print("Action2")
    })
    return [action1, action2]
}

For Kotlin simply:

import java.lang.reflect.Type
import com.google.gson.reflect.TypeToken
...
val type = object : TypeToken<List<T>>() {}.type

or, here is a useful function:

fun <T> typeOfList(): Type {
    return object : TypeToken<List<T>>() {}.type
}

Then, to use:

val type = typeOfList<YourMagicObject>()

This works:

package main

import (
    "fmt"
    "os"
    "os/signal"
    "syscall"
    "time" // or "runtime"
)

func cleanup() {
    fmt.Println("cleanup")
}

func main() {
    c := make(chan os.Signal)
    signal.Notify(c, os.Interrupt, syscall.SIGTERM)
    go func() {
        <-c
        cleanup()
        os.Exit(1)
    }()

    for {
        fmt.Println("sleeping...")
        time.Sleep(10 * time.Second) // or runtime.Gosched() or similar per @misterbee
    }
}

The % operator is for integers. You're looking for the fmod() function.

#include <cmath>

int main()
{
    double x = 6.3;
    double y = 2.0;
    double z = std::fmod(x,y);

}

When Command Extensions are enabled (Windows XP and newer, roughly), you can use the syntax %~nF (where F is the variable and ~n is the request for its name) to only get the filename.

FOR /R C:\Directory %F in (*.*) do echo %~nF

should echo only the filenames.

(SELECT ename FROM EMP WHERE empno = mgr)

There are no records in EMP that meet this criteria.

You need to self-join to get this relation.

SELECT e.ename AS Employee, e.empno, m.ename AS Manager, m.empno
FROM EMP AS e LEFT OUTER JOIN EMP AS m
ON e.mgr =m.empno;

EDIT:

The answer you selected will not list your president because it's an inner join. I'm thinking you'll be back when you discover your output isn't what your (I suspect) homework assignment required. Here's the actual test case:

> select * from emp;

 empno | ename |    job    | deptno | mgr  
-------+-------+-----------+--------+------
  7839 | king  | president |     10 |     
  7698 | blake | manager   |     30 | 7839
(2 rows)

> SELECT e.ename employee, e.empno, m.ename manager, m.empno
FROM emp AS e LEFT OUTER JOIN emp AS m
ON e.mgr =m.empno;

 employee | empno | manager | empno 
----------+-------+---------+-------
 king     |  7839 |         |      
 blake    |  7698 | king    |  7839
(2 rows)

The difference is that an outer join returns all the rows. An inner join will produce the following:

> SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM emp e, emp m
WHERE e.mgr = m.empno;

 ename | empno | manager | mgr  
-------+-------+---------+------
 blake |  7698 | king    | 7839
(1 row)

SELECT * FROM table SAMPLE(10) WHERE ROWNUM <= 20;

This is more efficient as it doesn't need to sort the Table.

These are much much better references than w3schools (the most awful web reference ever made):

• How cookies work (quirksmode.org)
• MDN document.cookie

Examples derived from these references:

// sets the cookie cookie1
document.cookie = 'cookie1=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// sets the cookie cookie2 (cookie1 is *not* overwritten)
document.cookie = 'cookie2=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// remove cookie2
document.cookie = 'cookie2=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/'

The Mozilla reference even has a nice cookie library you can use.

To all: Thanks for all the post and comments some are good, but some are better.

The first big script is good because it is delivers just what is needed. The fastest and most detailed is the one suggestion for selecting from INFORMATION_SCHEMA.COLUMNS..

My need was to find all the errant columns of approximately the same name and Several databases.. Sooo, I made my versions of both (see below) ...Either of these two below script work and deliver the goods in seconds.

The assumption in other posts on this link, is that the first code example can be used successfully with for-each-database, is to me, not desirable. This is because the information is within the specific database and the simple use of the "fedb" doesn't produce the correct results, it simply doesn't give access. SOOO to that is why I use a CURSOR to collect the databases and ignore those that are Off-line, which in this case, a utility script, it is a good use of same.

Bottom Line, I read everyone's post, incorporated all the correction from the posts and made what are two very eloquent scripts from others good works. I listed both below and have also placed the script file on my public folder at OneDrive.com which you can access with this link: http://1drv.ms/1vr8yNX

Use a do-while to design re-try block.

boolean successful = false;
int maxTries = 3;
do{
  try {
    something();
    success = true;
  } catch(Me ifUCan) {
    maxTries--;
  }
} while (!successful || maxTries > 0)

This operator allows you to determine the type of an object. It returns a boolean value.

For example

package test;

import java.util.Date;
import java.util.Map;
import java.util.HashMap;

public class instanceoftest
{
    public static void main(String args[])
    {
        Map m=new HashMap();
        System.out.println("Returns a boolean value "+(m instanceof Map));
        System.out.println("Returns a boolean value "+(m instanceof HashMap));
        System.out.println("Returns a boolean value "+(m instanceof Object));
        System.out.println("Returns a boolean value "+(m instanceof Date));
    }
} 

the output is:

Returns a boolean value true
Returns a boolean value true
Returns a boolean value true
Returns a boolean value false

You can try this id is tries

window.location.hash = '#tries';

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

Have a look at config.sample.inc.php: you will find examples of the configuration directives that you should copy to your config.inc.php (copy the missing ones). Then, have a look at examples/create_tables.sql which will help you create the missing tables.

The complete documentation for this is available at http://docs.phpmyadmin.net/en/latest/setup.html#phpmyadmin-configuration-storage.

When you use a string literal the string can be interned, but when you use new String("...") you get a new string object.

In this example both string literals refer the same object:

String a = "abc"; 
String b = "abc";
System.out.println(a == b);  // true

Here, 2 different objects are created and they have different references:

String c = new String("abc");
String d = new String("abc");
System.out.println(c == d);  // false

In general, you should use the string literal notation when possible. It is easier to read and it gives the compiler a chance to optimize your code.

The only problem with JSON in Java is that if your XML has a single child, but is an array, it will convert it to an object instead of an array. This can cause problems if you dynamically always convert from XML to JSON, where if your example XML has only one element, you return an object, but if it has 2+, you return an array, which can cause parsing issues for people using the JSON.

Infoscoop's XML2JSON class has a way of tagging elements that are arrays before doing the conversion, so that arrays can be properly mapped, even if there is only one child in the XML.

Here is an example of using it (in a slightly different language, but you can also see how arrays is used from the nodelist2json() method of the XML2JSON link).

Solution for Angular 2

Create a label on top of the select

<label class="hidden-label" for="IsActive"
    *ngIf="filterIsActive == undefined">Placeholder text</label>
<select class="form-control form-control-sm" type="text" name="filterIsActive"
    [(ngModel)]="filterIsActive" id="IsActive">
    <option value="true">true</option>
    <option value="false">false</option>
</select>

and apply CSS to place it on top

.hidden-label {
    position: absolute;
    margin-top: .34rem;
    margin-left: .56rem;
    font-style: italic;
    pointer-events: none;
}

pointer-events: none allows you to display the select when you click on the label, which is hidden when you select an option.

You should install python 3.6 version because python 3.7 version doesn't support pyaudio 1 step : Then download the .whl file
according to your python version and the configuration of your machine in your python folder which is newly installed. For me it is python 3.6 and 64 bit machine. Download the file from here (https://www.lfd.uci.edu/~gohlke/pythonlibs/) 2 step : run your cmd and type " pip install your downloaded file name here "

There is no way to do this with CSS, you could use PHP or Javascript for this.

PHP example:

$text = "ALL CAPS";
$text = ucwords(strtolower($text)); // All Caps

jQuery example (it's a plugin now!):

// Uppercase every first letter of a word
jQuery.fn.ucwords = function() {
  return this.each(function(){
    var val = $(this).text(), newVal = '';
    val = val.split(' ');

    for(var c=0; c < val.length; c++) {
      newVal += val[c].substring(0,1).toUpperCase() + val[c].substring(1,val[c].length) + (c+1==val.length ? '' : ' ');
    }
    $(this).text(newVal);
  });
}

$('a.link').ucwords();?

Here it worked on Mac OS X.

It includes the example of a BSD date, how to increment and decrement the date also:

for ((i=28; i>=6 ; i--));
do
    dat=`date -v-${i}d -j "+%Y%m%d"` 
    echo $dat
done

You could do this on the ASPX HTML front end to make the button go to a new tab to show page in your ASP.NET site dynamically:

        <asp:Button ID="btnNewEntry" CssClass="button"  OnClientClick="window.open('https://website','_blank'); return false;" text="WebsiteName"  runat="server" />

If you have untarred your own version of tomcat v8 with a root user into a custom directory (linux) then the default permissions on the TOMCATROOT/lib directory do not allow normal user access.

Eclipse will not be able to see the catalina.jar to check the version. So no amount of fiddling aorund with the server.properties will help!

just add chmod u+x lib/ to allow normal user access to the libs.

In addition, notice that if your mongo shell client fails to connect correctly to the mongod instance, you can receive such "Permission Denied" errors.

Make sure that your client opens a connection by checking the connection port, but also that the port you are using in mongod is not in use. You can set a different port by using the --port <port> parameter in both the shell and the process.

I know i reopen this old task but with c# 4.0 this task is absolutely painless.

function isSet(iVal){
 return (iVal!=="" && iVal!=null && iVal!==undefined && typeof(iVal) != "undefined") ? 1 : 0;
} // Returns 1 if set, 0 false

I encountered this limitation too and created this library to overcome the issue: spring-boot-jar-resources It basically allows you to register a custom ResourceLoader with Spring Boot that extracts the classpath resources from the JAR as needed, transparently.

When page is load then scroll is max value .

This is message box when user send message then always show latest chat in down so that scroll value is always is maxium.

$('#message').scrollTop($('#message')[0].scrollHeight);

The specific problem is that you're declaring a new variable instead of assigning to an existing one:

char * ret = new char[strlen(array) + 1 + 1];
^^^^^^ Remove this

and trying to compare string values by comparing pointers:

if (array!="")     // Wrong - compares pointer with address of string literal
if (array[0] == 0) // Better - checks for empty string

although there's no need to make that comparison at all; the first branch will do the right thing whether or not the string is empty.

The more general problem is that you're messing around with nasty, error-prone C-style string manipulation in C++. Use std::string and it will manage all the memory allocation for you:

std::string appendCharToString(std::string const & s, char a) {
    return s + a;
}

I would use this syntax

Delete a 
from TableA a
Inner Join TableB b
on  a.BId = b.BId
WHERE [filter condition]

Maybe concatenate the current working directory with argv[0]? I'm not sure if that would work in Windows but it works in linux.

For example:

#include <stdio.h>
#include <unistd.h>
#include <string.h>

int main(int argc, char **argv) {
    char the_path[256];

    getcwd(the_path, 255);
    strcat(the_path, "/");
    strcat(the_path, argv[0]);

    printf("%s\n", the_path);

    return 0;
}

When run, it outputs:

jeremy@jeremy-desktop:~/Desktop$ ./test
/home/jeremy/Desktop/./test

Instead of instantiating as follows:

TestRestTemplate restTemplate = new TestRestTemplate();

Just do it like this:

TestRestTemplate restTemplate = new TestRestTemplate(user, password);

It works for me, I hope it helps!

As an empty string is not valid JSON it would be incorrect for JSON.parse('') to return null because "null" is valid JSON. e.g.

JSON.parse("null");

returns null. It would be a mistake for invalid JSON to also be parsed to null.

While an empty string is not valid JSON two quotes is valid JSON. This is an important distinction.

Which is to say a string that contains two quotes is not the same thing as an empty string.

JSON.parse('""');

will parse correctly, (returning an empty string). But

JSON.parse('');

will not.

Valid minimal JSON strings are

The empty object '{}'

The empty array '[]'

The string that is empty '""'

A number e.g. '123.4'

The boolean value true 'true'

The boolean value false 'false'

The null value 'null'

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

Use CSS grid and set all the grid items to be in the same cell.

.layered {
  display: grid;
}

.layered > * {
  grid-column-start: 1;
  grid-row-start: 1;
}

Adding the layered class to an element causes all it's children to be layered on top of each other.

if the layers are not the same size you can set the justify-items and align-items properties to set the horizontal and vertical alignment respectively.

Demo:

JsFiddle

.layered {
  display: grid;

  /* Set horizontal alignment of items in, case they have a different width. */
  /* justify-items: start | end | center | stretch (default); */
  justify-items: start;

  /* Set vertical alignment of items, in case they have a different height. */
  /* align-items: start | end | center | stretch (default); */
  align-items: start;
}

.layered > * {
  grid-column-start: 1;
  grid-row-start: 1;
}


/* for demonstration purposes only */
.layered > * {
  outline: 1px solid red;
  background-color: rgba(255, 255, 255, 0.4)
}

<div class="layered">
  <img src="https://via.placeholder.com/250x100?text=first" />
  <p>
    2
  </p>
  <div>
    <p>
      Third layer
    </p>
    <p>
      Third layer continued
    </p>
    <p>
      Third layer continued
    </p>
    <p>

I think I found what you are looking for since I was also looking for it.

You have to follow Pawel's steps and then go to the key that is "Cookie". This will open a submenu with all the cookies and it specifies their name, value, domain, etc...

Respectively the values are: Key, Value, Expiration Date, Domain, Path.

This shows all the keys for this domain.

So again to get there:

1. Go to Network.
2. Capture Traffic, green triangle.
3. Go to Details.
4. Go to the "Cookie" key that has a gibberish value. (_utmc=xxxxx;something=ajksdhfa) etc...

Login into the database. then run the below query

select * from dba_role_privs where grantee = 'SCHEMA_NAME';

All the role granted to the schema will be listed.

Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.

The code below will check whether the stored procedure already exists or not.

If it exists it will alter, if it doesn't exist it will create a new stored procedure for you:

//syntax for Create and Alter Proc 
DECLARE @Create NVARCHAR(200) = 'Create PROCEDURE sp_cp_test'; 
DECLARE @Alter NVARCHAR(200) ='Alter PROCEDURE sp_cp_test'; 
//Actual Procedure 
DECLARE @Proc NVARCHAR(200)= ' AS BEGIN select ''sh'' END'; 
//Checking For Sp
IF EXISTS (SELECT * 
           FROM   sysobjects 
           WHERE  id = Object_id('[dbo].[sp_cp_test]') 
                  AND Objectproperty(id, 'IsProcedure') = 1 
                  AND xtype = 'p' 
                  AND NAME = 'sp_cp_test') 
  BEGIN 
      SET @Proc=@Alter + @Proc 

      EXEC (@proc) 
  END 
ELSE 
  BEGIN 
      SET @Proc=@Create + @Proc 

      EXEC (@proc) 
  END 

go 

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

Use a return statement!

return;

or

if (condition) return;

You don't need to (and can't) specify any values, if your method returns void.

If you are thinking into using Tensorflow c++ api on a standalone package you probably will need tensorflow_cc.so ( There is also a c api version tensorflow.so ) to build the c++ version you can use:

bazel build -c opt //tensorflow:libtensorflow_cc.so

Note1: If you want to add intrinsics support you can add this flags as: --copt=-msse4.2 --copt=-mavx

Note2: If you are thinking into using OpenCV on your project as well, there is an issue when using both libs together (tensorflow issue) and you should use --config=monolithic.

After building the library you need to add it to your project. To do that you can include this paths:

tensorflow
tensorflow/bazel-tensorflow/external/eigen_archive
tensorflow/bazel-tensorflow/external/protobuf_archive/src
tensorflow/bazel-genfiles

And link the library to your project:

tensorflow/bazel-bin/tensorflow/libtensorflow_framework.so (unused if you build with --config=monolithic)
tensorflow/bazel-bin/tensorflow/libtensorflow_cc.so

And when you are building your project you should also specify to your compiler that you are going to use c++11 standards.

Side Note: Paths relative to tensorflow version 1.5 (You may need to check if in your version anything changed).

Also this link helped me a lot into finding all this infos: link

My method can be proceeded via bash terminal/console

1) run and get the process number

$ ps aux | grep yourAppKeywords

2a) kill the process

$ kill processNum

2b) kill the process if above not working

$ kill -9 processNum

In php, we have two option to concatenate table columns.

First Option using Query

In query, CONCAT keyword used to concatenate two columns

SELECT CONCAT(`SUBJECT`,'_', `YEAR`) AS subject_year FROM `table_name`;

Second Option using symbol ( . )

After fetch the data from database table, assign the values to variable, then using ( . ) Symbol and concatenate the values

$subject = $row['SUBJECT'];
$year = $row['YEAR'];
$subject_year = $subject . "_" . $year;

Instead of underscore( _ ) , we will use the spaces, comma, letters,numbers..etc

When I needed to do this, I followed Microsoft's example using Binding.ValidationRules and it worked first time.

See their article, How to: Implement Binding Validation: https://docs.microsoft.com/en-us/dotnet/desktop/wpf/data/how-to-implement-binding-validation?view=netframeworkdesktop-4.8

SSL certificates are bound to a 'common name', which is usually a fully qualified domain name but can be a wildcard name (eg. *.domain.com) or even an IP address, but it usually isn't.

In your case, you are accessing your LDAP server by a hostname and it sounds like your two LDAP servers have different SSL certificates installed. Are you able to view (or download and view) the details of the SSL certificate? Each SSL certificate will have a unique serial numbers and fingerprint which will need to match. I assume the certificate is being rejected as these details don't match with what's in your certificate store.

Your solution will be to ensure that both LDAP servers have the same SSL certificate installed.

BTW - you can normally override DNS entries on your workstation by editing a local 'hosts' file, but I wouldn't recommend this.

Use DateFormat. For example,

SimpleDateFormat isoFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
isoFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
Date date = isoFormat.parse("2010-05-23T09:01:02");

Docotic.Pdf library can be easily used to create PDF files at runtime. The library can also modify existing PDF documents (extract text/images, append pages, fill form fields, etc.)

Samples for common tasks are available on the library site.

To settext in any of in activity than use this below code... Follow these step one by one:

1.Declare

    private TextView event_post;

2.Bind this

    event_post = (TextView) findViewById(R.id.text_post);

3.SetText in

    event_post.setText(event_post_count);

add this code to your project

  public static class Extension {
        public static string TextAfter(this string value ,string search) {
            return  value.Substring(value.IndexOf(search) + search.Length);
        }
  }

then use

"code : string text ".TextAfter(":")

Use open(fn, 'rb').read().decode('utf-8') instead of just open(fn).read()

This worked for me. I made a function. Put this in your shell script:

sshcmd(){
    ssh $1@$2 $3
}

sshcmd USER HOST COMMAND

If you have multiple machines that you want to do the same command on you would repeat that line with a semi colon. For example, if you have two machines you would do this:

sshcmd USER HOST COMMAND ; sshcmd USER HOST COMMAND

Replace USER with the user of the computer. Replace HOST with the name of the computer. Replace COMMAND with the command you want to do on the computer.

Hope this helps!

You can use numpy's slicing, simply start:stop:step.

>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])

This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2]         # O(1), constant time
>>> b[:] = 0           # modifying the view changes original array
>>> a                  # original array is modified
array([0, 2, 0, 4, 0])

so if either of the above things are a problem, you can make a copy explicitly:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy()  # explicit copy, O(n)
>>> b[:] = 0           # modifying the copy
>>> a                  # original is intact
array([1, 2, 3, 4, 5])

This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.

This should further clarify the points:

a = int(raw_input('Enter the index'))
str1 = 'Example'
leng = len(str1)
if (a < (len-1)) and (a > (-len)):
    print str1[a]
else:
    print('Index overflow')

Input 3 Output m

Input -3 Output p

1. Include the Open Graph XML namespace extension to your HTML declaration

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:fb="http://ogp.me/ns/fb#">

2. Inside your <head></head> use the following meta tag to define the image you want to use

<meta property="og:image" content="fully_qualified_image_url_here" />

Read more about open graph protocol here.

After doing the above, use the Facebook "Object Debugger" if the image does not show up correctly. Also note the first time shared it still won't show up unless height and width are also specified, see Share on Facebook - Thumbnail not showing for the first time

The problem I see here is that "sum" is an aggregate function.

first, you need to fix the query itself.

Select sum(c_counts + f_counts) total, [column to group sums by]
from table
group by [column to group sums by]

then, you can sort it:

Select *
from (query above) a
order by total

EDIT: But see post by Virat. Perhaps what you want is not the sum of your total fields over a group, but just the sum of those fields for each record. In that case, Virat has the right solution.

What I've done to solve the same problem is to have a feature detection (I use something like this code), seeing if onTouchMove is defined, and if so I add the css class "touchMode" to the body, else i add "desktopMode".

Then every time some style effect only applies to a touch device, or only to a desktop the css rule is prepended with the appropriate class:

.desktopMode .someClass:hover{ color: red }
.touchMode .mainDiv { width: 100%; margin: 0; /*etc.*/ }

Edit: This strategy of course adds a few extra characters to your css, so If you're concerned about css size, you could search for the touchMode and desktopMode definitons and put them into different files, so you can serve optimized css for each device type; or you could change the class names to something much shorter before going to prod.

You can use this command.

git diff --cached --name-only

The --cached option of git diff means to get staged files, and the --name-only option means to get only names of the files.

This Blog article explains the internals of ODEX files:

WHAT IS AN ODEX FILE?

In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.

The single-step answer to the first question is to use something like:

update TBL set CLM = CLM + 1 where key = 'KEY'

That's very much a single-instruction way of doing it.

As for the second question, you shouldn't need to resort to DBMS-specific SQL gymnastics (like UPSERT) to get the result you want. There's a standard method to do update-or-insert that doesn't require a specific DBMS.

try:
    insert into TBL (key,val) values ('xyz',0)
catch:
    do nothing
update TBL set val = val + 1 where key = 'xyz'

That is, you try to do the creation first. If it's already there, ignore the error. Otherwise you create it with a 0 value.

Then do the update which will work correctly whether or not:

• the row originally existed.
• someone updated it between your insert and update.

It's not a single instruction and yet, surprisingly enough, it's how we've been doing it successfully for a long long time.

Start GDB on your project.

1. Go to project directory, where you've already compiled the project executable. Issue the command gdb and the name of the executable as below:

   gdb projectExecutablename

This starts up gdb, prints the following: GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.04) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc. ................................................. Type "apropos word" to search for commands related to "word"... Reading symbols from projectExecutablename...done. (gdb)

2. Before you start your program running, you want to set up your breakpoints. The break command allows you to do so. To set a breakpoint at the beginning of the function named main:

   (gdb) b main

3. Once you've have the (gdb) prompt, the run command starts the executable running. If the program you are debugging requires any command-line arguments, you specify them to the run command. If you wanted to run my program on the "xfiles" file (which is in a folder "mulder" in the project directory), you'd do the following:

   (gdb) r mulder/xfiles

Hope this helps.

Disclaimer: This solution is not mine, it is adapted from https://web.stanford.edu/class/cs107/guide_gdb.html This short guide to gdb was, most probably, developed at Stanford University.

You can use \D which means non digits.

var removedText = self.val().replace(/\D+/g, '');

jsFiddle.

You could also use the HTML5 number input.

<input type="number" name="digit" />

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

I just add this line exactly as it appears below (if you need a second delay):

try {
    Thread.sleep(1000);
} catch(InterruptedException e) {
    // Process exception
}

I find the catch IS necessary (Your app can crash due to Android OS as much as your own code).

check if a user exists or not. If not insert

$exist = DB::table('User')->where(['username'=>$username,'password'=>$password])->get();
if(count($exist)  >0) {
    echo "User already exist";;
}
else  {
    $data=array('username'=>$username,'password'=>$password);
    DB::table('User')->insert($data);
}

You don't need an external library for this. The below code works for LINQ to SQL/entities.

    /// <summary>
    /// Sorts the elements of a sequence according to a key and the sort order.
    /// </summary>
    /// <typeparam name="TSource">The type of the elements of <paramref name="query" />.</typeparam>

    /// <param name="key">Name of the property of <see cref="TSource"/> by which to sort the elements.</param>
    /// <param name="ascending">True for ascending order, false for descending order.</param>
    /// <returns>An <see cref="T:System.Linq.IOrderedQueryable`1" /> whose elements are sorted according to a key and sort order.</returns>
    public static IQueryable<TSource> OrderBy<TSource>(this IQueryable<TSource> query, string key, bool ascending = true)
    {
        if (string.IsNullOrWhiteSpace(key))
        {
            return query;
        }

        var lambda = (dynamic)CreateExpression(typeof(TSource), key);

        return ascending 
            ? Queryable.OrderBy(query, lambda) 
            : Queryable.OrderByDescending(query, lambda);
    }

    private static LambdaExpression CreateExpression(Type type, string propertyName)
    {
        var param = Expression.Parameter(type, "x");

        Expression body = param;
        foreach (var member in propertyName.Split('.'))
        {
            body = Expression.PropertyOrField(body, member);
        }

        return Expression.Lambda(body, param);
    }

Yes.

while read in; do chmod 755 "$in"; done < file.txt

This way you can avoid a cat process.

cat is almost always bad for a purpose such as this. You can read more about Useless Use of Cat.

In addition to the accepted answer, you can also achieve what you originally wanted (creating a deployment using the run command) with the following command:

kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989 --generator=run-pod/v1 

I found the information about the generator on the Kubernetes-dev forum:

If you're using kubectl run, it generates a manifest for you that happens to have imagePullPolicy set to Always by default. You can use this command to get an imagePullPolicy of IfNotPresent, which will work for minikube:

kubectl run --image=<container> --generator=run-pod/v1

I like Kango_V's answer, but I think it's too complex. I think this is simpler - maybe too simple. If inclined, you could replace String with a Generic marker, and make it work for any Key type.

public static <E> Map<String, E> convertListToMap(Collection<E> sourceList, ListToMapConverterInterface<E> converterInterface) {
    Map<String, E> newMap = new HashMap<String, E>();
    for( E item : sourceList ) {
        newMap.put( converterInterface.getKeyForItem( item ), item );
    }
    return newMap;
}

public interface ListToMapConverterInterface<E> {
    public String getKeyForItem(E item);
}

Used like this:

        Map<String, PricingPlanAttribute> pricingPlanAttributeMap = convertListToMap( pricingPlanAttributeList,
                new ListToMapConverterInterface<PricingPlanAttribute>() {

                    @Override
                    public String getKeyForItem(PricingPlanAttribute item) {
                        return item.getFullName();
                    }
                } );

As Carlos Rincones suggested; don't be affraid of playing with superglobals.

$files = $_FILES;

for($i=0; $i<count($files['userfile']['name']); $i++)
{
    $_FILES = array();
    foreach( $files['userfile'] as $k=>$v )
    {
        $_FILES['userfile'][$k] = $v[$i];                
    }

    $this->upload->do_upload('userfile')
}

You could do something really sweet by using JNI like this:

MyObject.java:

public class MyObject
{
    static
    {
        System.loadLibrary( "classname" );
    }

    public static native String getClassName();

    public static void main( String[] args )
    {
        System.out.println( getClassName() );
    }
}

then:

javac MyObject.java
javah -jni MyObject

then:

MyObject.c:

#include "MyObject.h"

JNIEXPORT jstring JNICALL Java_MyObject_getClassName( JNIEnv *env, jclass cls )
{
    jclass javaLangClass = (*env)->FindClass( env, "java/lang/Class" );
    jmethodID getName = (*env)->GetMethodID( env, javaLangClass, "getName",
        "()Ljava/lang/String;" );
    return (*env)->CallObjectMethod( env, cls, getName );
}

Then compile the C up into a shared library called libclassname.so and run the java!

It wouldn't be wrong to mention that Pexpect does throw a similar error

#python -c "import pexpect; p=pexpect.spawn('/usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
Traceback (most recent call last):

OSError: [Errno 8] Exec format error

Over here, the openssl_1.1.0f file at the specified path has exec command specified in it and is running the actual openssl binary when called.

Usually, I wouldn't mention this unless I have the root cause, but this problem was not there earlier. Unable to find the similar problem, the closest explanation to make it work is the same as the one provided by @jfs above.

what worked for me is both

• adding /bin/bash at the beginning of the command or file you are
  facing the problem with, or
• adding shebang #!/bin/sh as the first line.

for ex.

#python -c "import pexpect; p=pexpect.spawn('/bin/bash /usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
