All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

I checked the version of my google chrome browser installed on my pc and then downloaded ChromeDriver suited to my browser version. You can download it from https://chromedriver.chromium.org/

I had the same issue when Cloning the repository via Bash/VS Code with "fatal:Authentication failed". I used SSH Key authentication instead to connect my repository following the article: [https://docs.microsoft.com/en-us/azure/devops/repos/git/use-ssh-keys-to-authenticate?view=azure-devops&tabs=current-page][1] I didn't get any errors after with any bash commands!

Using React Hooks also don't forget to set the initial value.
I was using <input type='datetime-local' value={eventStart} /> and initial eventStart was like

const [eventStart, setEventStart] = useState();
instead
const [eventStart, setEventStart] = useState('');.

The empty string in parentheses is difference.
Also, if you reset form after submit like i do, again you need to set it to empty string, not just to empty parentheses.

This is just my small contribution to this topic, maybe it will help someone.

clear site data in your browser. and it will be fixed. sometimes when you run proxies, vpns or some other programs this error happens.

This is the Different Solution, Check if your Services are running correctly, if WAMP icon showing orange color, and 2 out of 3 services are running it's showing, then this solution will work . Root cause:

If in your system mysql was there, later you installed WAMP then again one MYSQL will install as WAMP package, default port for MYSQL is 3306 , So in both mysql the port will be 3306, which is a port conflict, So just change the port it will work fine. Steps to change the Port.

1. Right click the WAMP icon.
2. Chose Tool
3. Change the port in Port used by MySql Section

After reading through manny forums found a really easy solution.

I use redux-form. Urgo mapped redux-from fieldToClass. Upon error I navigate to the first error on the list of syncErrors.

No refs and no third party modules. Just simple querySelector & scrollIntoView

handleToScroll = (field) => {

    const fieldToClass = {
        'vehicleIdentifier': 'VehicleIdentifier',
        'locationTags': 'LocationTags',
        'photos': 'dropzoneContainer',
        'description': 'DescriptionInput',
        'clientId': 'clientId',
        'driverLanguage': 'driverLanguage',
        'deliveryName': 'deliveryName',
        'deliveryPhone': 'deliveryPhone',
        "deliveryEmail": 'deliveryEmail',
        "pickupAndReturn": "PickupAndReturn",
        "payInCash": "payInCash",
    }

document?.querySelector(`.${fieldToClasses[field]}`)
         .scrollIntoView({ behavior: "smooth" })

}

If the problem is not solved by above answer, check whether the Windows SDK version is 10.0.15063.0.

Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0

After this rebuild the solution.  

In case anyone else comes across this problem, if you have already laid the page out, I would recommend using media queries to set up your print page. You can then simply attach a print function to your html button and in your component call window.print();

component.html:

<div class="doNotPrint">
    Header is here.
</div>

<div>
    all my beautiful print-related material is here.
</div>

<div class="doNotPrint">
    my footer is here.
    <button (click)="onPrint()">Print</button>
</div>

component.ts:

onPrint(){
    window.print();
}

component.css:

@media print{
  .doNotPrint{display:none !important;}
}

You can optionally also add other elements / sections you do not wish to print in the media query.

You can change the document margins and all in the print query as well, which makes it quite powerful. There are many articles online. Here is one that seems comprehensive: https://www.sitepoint.com/create-a-customized-print-stylesheet-in-minutes/ It also means you don't have to create a separate script to create a 'print version' of the page or use lots of javascript.

Try this, example, the required property in below input tag will ensure that the name field should be submitted empty.

<input type="text" placeholder="Your Name" required />

As a generic answer, not specifically directed at this task: In many cases, you can significantly speed up any program by making improvements at a high level. Like calculating data once instead of multiple times, avoiding unnecessary work completely, using caches in the best way, and so on. These things are much easier to do in a high level language.

Writing assembler code, it is possible to improve on what an optimising compiler does, but it is hard work. And once it's done, your code is much harder to modify, so it is much more difficult to add algorithmic improvements. Sometimes the processor has functionality that you cannot use from a high level language, inline assembly is often useful in these cases and still lets you use a high level language.

In the Euler problems, most of the time you succeed by building something, finding why it is slow, building something better, finding why it is slow, and so on and so on. That is very, very hard using assembler. A better algorithm at half the possible speed will usually beat a worse algorithm at full speed, and getting the full speed in assembler isn't trivial.

It is important to remember that React expects STABLE keys, meaning you should assign the keys once and every item on your list should receive the same key every time, that way React can optimize around your data changes when it is reconciling the virtual DOM and decides which components need to re-render. So, if you are using UUID you need to do it at the data level, not at the UI level.

Also keep in mind you can use any string you want for the key, so you can often combine several fields into one unique ID, something like ${username}_${timestamp} can be a fine unique key for a line in a chat, for example.

This just happened to me.

• I made a pull request to our master yesterday.
• My colleague was reviewing it today and saw that it was out of sync with our master branch, so with the intention of helping me, he merged master to my branch.
• I didn't know he did that.
• Then I merged master locally, tried to push it, but it failed. Why? Because my colleague merge with master created an extra commit I did not have locally!

Solution: Pull down my own branch so I get that extra commit. Then push it back to my remote branch.

literally what I did on my branch was:

git pull
git push

If you are a python user -
Create a requirements.txt file preferably using pip freeze > requirements.txt.
Add, commit and try pushing it again.

If this doesn't work try deleting .git (beware this might remove the associated git history) and follow the above steps again.

Worked for me.

You have duplicated export default declaration. The first one get overridden by second one which is actually a function.

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

Using Ref forwarding you can pass the ref from parent to further down to a child.

const FancyButton = React.forwardRef((props, ref) => (
  <button ref={ref} className="FancyButton">
    {props.children}
  </button>
));

// You can now get a ref directly to the DOM button:
const ref = React.createRef();
<FancyButton ref={ref}>Click me!</FancyButton>;

1. Create a React ref by calling React.createRef and assign it to a ref variable.
2. Pass your ref down to by specifying it as a JSX attribute.
3. React passes the ref to the (props, ref) => ... function inside forwardRef as a second argument.
4. Forward this ref argument down to by specifying it as a JSX attribute.
5. When the ref is attached, ref.current will point to the DOM node.

Note The second ref argument only exists when you define a component with React.forwardRef call. Regular functional or class components don’t receive the ref argument, and ref is not available in props either.

Ref forwarding is not limited to DOM components. You can forward refs to class component instances, too.

Reference: React Documentation.

Yes there is a difference!

The immediate effect of using innerHTML versus dangerouslySetInnerHTML is identical -- the DOM node will update with the injected HTML.

However, behind the scenes when you use dangerouslySetInnerHTML it lets React know that the HTML inside of that component is not something it cares about.

Because React uses a virtual DOM, when it goes to compare the diff against the actual DOM, it can straight up bypass checking the children of that node because it knows the HTML is coming from another source. So there's performance gains.

More importantly, if you simply use innerHTML, React has no way to know the DOM node has been modified. The next time the render function is called, React will overwrite the content that was manually injected with what it thinks the correct state of that DOM node should be.

Your solution to use componentDidUpdate to always ensure the content is in sync I believe would work but there might be a flash during each render.

This can also happen if you/someone renamed the branch. So follow these steps (if you know that branch name is renamed) Assuming earlier branch name as wrong-branch-name and someone renamed it to correct-branch-name So.

git checkout correct-branch-name

git pull (you'll see this "Your configuration specifies..")

git branch --unset-upstream

git push --set-upstream origin correct-branch-name

git pull (you'll not get the earlier message )

Toggle function in react

At first you should create constructor like this

constructor(props) {
        super(props);
        this.state = {
            close: true,
        };
    }

Then create a function like this

yourFunction = () => {
        this.setState({
            close: !this.state.close,
        });
    };

then use this like

render() {
        const {close} = this.state;
        return (

            <Fragment>

                 <div onClick={() => this.yourFunction()}></div>

                 <div className={close ? "isYourDefaultClass" : "isYourOnChangeClass"}></div>

            </Fragment>
        )
    }
}

Please give better solutions

If you need to handle DOM events not already provided by React you have to add DOM listeners after the component is mounted:

Update: Between React 13, 14, and 15 changes were made to the API that affect my answer. Below is the latest way using React 15 and ES7. See answer history for older versions.

class MovieItem extends React.Component {

  componentDidMount() {
    // When the component is mounted, add your DOM listener to the "nv" elem.
    // (The "nv" elem is assigned in the render function.)
    this.nv.addEventListener("nv-enter", this.handleNvEnter);
  }

  componentWillUnmount() {
    // Make sure to remove the DOM listener when the component is unmounted.
    this.nv.removeEventListener("nv-enter", this.handleNvEnter);
  }

  // Use a class arrow function (ES7) for the handler. In ES6 you could bind()
  // a handler in the constructor.
  handleNvEnter = (event) => {
    console.log("Nv Enter:", event);
  }

  render() {
    // Here we render a single <div> and toggle the "aria-nv-el-current" attribute
    // using the attribute spread operator. This way only a single <div>
    // is ever mounted and we don't have to worry about adding/removing
    // a DOM listener every time the current index changes. The attrs 
    // are "spread" onto the <div> in the render function: {...attrs}
    const attrs = this.props.index === 0 ? {"aria-nv-el-current": true} : {};

    // Finally, render the div using a "ref" callback which assigns the mounted 
    // elem to a class property "nv" used to add the DOM listener to.
    return (
      <div ref={elem => this.nv = elem} aria-nv-el {...attrs} className="menu_item nv-default">
        ...
      </div>
    );
  }

}

Just for the record, if you are using eslint-plugin-vue, the correct place to add 'parser': 'babel-eslint' is inside parserOptions param.

  'parserOptions': {
    'parser': 'babel-eslint',
    'ecmaVersion': 2018,
    'sourceType': 'module'
  }

You are just missing the first argument to connect, which is the mapStateToProps method. Excerpt from the Redux todo app:

const mapStateToProps = (state) => {
  return {
    todos: getVisibleTodos(state.todos, state.visibilityFilter)
  }
}

const mapDispatchToProps = (dispatch) => {
  return {
    onTodoClick: (id) => {
      dispatch(toggleTodo(id))
    }
  }
}

const VisibleTodoList = connect(
  mapStateToProps,
  mapDispatchToProps
)(TodoList)

#Try without dot notation
sample_dict = {'name': 'John', 'age': 29}
print(sample_dict['name']) # John
print(sample_dict['age']) # 29

Having reviewed a few different large scale React/Redux projects in my experience Sagas provide developers a more structured way of writing code that is much easier to test and harder to get wrong.

Yes it is a little wierd to start with, but most devs get enough of an understanding of it in a day. I always tell people to not worry about what yield does to start with and that once you write a couple of test it will come to you.

I have seen a couple of projects where thunks have been treated as if they are controllers from the MVC patten and this quickly becomes an unmaintable mess.

My advice is to use Sagas where you need A triggers B type stuff relating to a single event. For anything that could cut across a number of actions, I find it is simpler to write customer middleware and use the meta property of an FSA action to trigger it.

Having named method in place of the anonymous function in audioNode.addEventListener 's callback should eliminate the subject warning:

    componentDidMount(prevProps, prevState, prevContext) {
    let [audioNode, songLen] = [this.refs.audio, List.length-1];

    audioNode.addEventListener('ended', () => {
        this._endedPlay(songLen, () => {
            this._currSong(this.state.songIndex);
            this._Play(audioNode);
        });
    });

    audioNode.addEventListener('timeupdate', this.callbackMethod );
}

callBackMethod = () => {
    let [remainTime, remainTimeMin, remainTimeSec, remainTimeInfo] = [];

    if(!isNaN(audioNode.duration)) {
        remainTime = audioNode.duration - audioNode.currentTime;
        remainTimeMin = parseInt(remainTime/60);  // ???
        remainTimeSec = parseInt(remainTime%60);  // ???

        if(remainTimeSec < 10) {
            remainTimeSec = '0'+remainTimeSec;
        }
        remainTimeInfo = remainTimeMin + ':' + remainTimeSec;
        this.setState({'time': remainTimeInfo});
    }
}

And yes, named method is needed anyways because removeEventListener won't work with anonymous callbacks, as mentioned above several times.

For me the following simple change worked perfectly

<input type="text" 
        value={props.letter} 
        onChange={event => setTxtLetter(event.target.value)} /> {/* does not work */}

change... value={myPropVal} to... defaultValue={myPropVal}

<input type="text" 
        defaultValue={props.letter} 
        onChange={event => setTxtLetter(event.target.value)} /> {/* Works!! */}

From React type definition

    type ReactInstance = Component<any, any> | Element;
....
    refs: {
            [key: string]: ReactInstance
    };

So you can access you refs element as follow

stepInput = () => ReactDOM.findDOMNode(this.refs['stepInput']);

without redefinition of refs index.

As @manakor mentioned you can get error like

Property 'stepInput' does not exist on type '{ [key: string]: Component | Element; }

if you redefine refs(depends on IDE and ts version you use)

Change <button type="button" to <button type="submit". Remove the onClick. Instead do <form className="commentForm" onSubmit={this.onFormSubmit}>. This should catch clicking the button and pressing the return key.

onFormSubmit = e => {
  e.preventDefault();
  const { name, email } = this.state;
  // send to server with e.g. `window.fetch`
}

...

<form onSubmit={this.onFormSubmit}>
  ...
  <button type="submit">Submit</button>
</form>

This piece of code worked for me. What I was missing was I was not passing 'this' in button action:

 onPress={this._handlePress.bind(this)}>
--------------

  _handlePress(event) {
console.log('Pressed!');

 var username = this.state.username;
 var password = this.state.password;

 console.log(username);
 console.log(password);
}

  render() {
    return (
      <View style={styles.container}>

      <TextInput
      ref="usr"
      style={{height: 40, borderColor: 'gray', borderWidth: 1 , marginTop: 10 , padding : 10 , marginLeft : 5 , marginRight : 5 }}
      placeHolder= "Enter username "
      placeholderTextColor = '#a52a2a'

      returnKeyType = {"next"}
      autoFocus = {true}
      autoCapitalize = "none"
      autoCorrect = {false}
      clearButtonMode = 'while-editing'
      onChangeText={(text) => {
          this.setState({username:text});
        }}
      onSubmitEditing={(event) => {
     this.refs.psw.focus();

      }}
      />

      <TextInput
      ref="psw"
      style={{height: 40, borderColor: 'gray', borderWidth: 1 , marginTop: 10,marginLeft : 5 , marginRight : 5}}
      placeholder= "Enter password"
      placeholderTextColor = '#a52a2a'
      autoCapitalize = "none"
      autoCorrect = {false}
      returnKeyType = {'done'}
      secureTextEntry = {true}
      clearButtonMode = 'while-editing'
      onChangeText={(text) => {
          this.setState({password:text});
        }}
      />

      <Button
        style={{borderWidth: 1, borderColor: 'blue'}}
        onPress={this._handlePress.bind(this)}>
        Login
      </Button>

      </View>
    );``
  }
}

I do realize that the author asks question in relation to a class-based component, however I think it's worth mentioning that as of React 16.8.0 (February 6, 2019) you can take advantage of hooks in function-based components.

Example code:

import { useRef } from 'react'

function Component() {
  const inputRef = useRef()

  return (
    <input ref={inputRef} />
    <div
      onScroll={() => {
        const { offsetTop } = inputRef.current
        ...
      }}
    >
  )
}

The above solutions explain clearly what the problem is; when you don't have control over the repo, the best way to submit your code is to create a Fork of the original repo and submit your code to this new repo so later you can push it to the original one.

Using constants allows to combine multiple fields for verification:

      }
   ...
  
      return(
       ...
       <TextField
        id="myTextField"
        label="Text Field"
        variant="outlined"
        inputRef={textFieldRef}
       />
       ...
      )

}

Note that this isn't complete code.

Amazon EBS provides block level storage - It is used to create a filesystem on it and store files. Amazon EFS - its shared storage system similar like NAS/SAN. You need to mount it to unix server and use it. Amazon S3 - It is object based storage where each item is stored with a http URL.

One of the difference is - EBS can be attached to 1 instance at a time and EFS can be attached to multiple instances that why shared storage. S2 plain object storage cannot be mounted.

Ok, I think I was able to find a proper solution for that.

Now, instead of sending <Link/> as prop to Document, I send <NextLink/> which is a custom wrapper for the react-router Link. By doing that, I'm able to have the right arrow as part of the Link structure while still avoiding to have routing code inside Document object.

The updated code looks like follows:

//in NextLink.js
var React = require('react');
var Right = require('./Right');

var NextLink = React.createClass({
    propTypes: {
        link: React.PropTypes.node.isRequired
    },

    contextTypes: {
        transitionTo: React.PropTypes.func.isRequired
    },

    _onClickRight: function() {
        this.context.transitionTo(this.props.link.props.to);
    },

    render: function() {
        return (
            <div>
                {this.props.link}
                <Right onClick={this._onClickRight} />
            </div>  
        );
    }
});

module.exports = NextLink;

...
//in MasterPage.js
var sampleLink = <Link to="/sample">Go To Sample</Link>
var nextLink = <NextLink link={sampleLink} />
<Document next={nextLink} />

//in Document.js
...
var Document = React.createClass({
   render: function() {
      return (
         ...
         <div>{this.props.next}</div>
         ...
      );
   }
});
...

P.S: If you are using the latest version of react-router you may need to use this.context.router.transitionTo instead of this.context.transitionTo. This code will work fine for react-router version 0.12.X.

This is the proper way, how to autofocus. When you use callback instead of string as ref value, it is automatically called. You got your ref available than without the need of touching the DOM using getDOMNode

render: function() {
  return <TextInput ref={(c) => this._input = c} />;
},
componentDidMount: function() {
  this._input.focus();
},

In my case I solved the problem by establishing a valid column number when applying the order property inside the script where you configure the data table.

var table = $('#mytable').DataTable({
     .
     .
     .
     order: [[ 1, "desc" ]],

--force option worked for me I used git push origin master --force

Despite the question is specific to gitlab, but similar errors can happen on github, depending how it is set up (usually Github Enterprise).

You need to familiarize yourself with the following concepts:

• pre-receive hooks
• organization webhooks
• Webhooks

Webhooks are more commonly understood than other two items.

The Pre-receive hooks

are scripts that run on the GitHub Enterprise server to enforce policy. When a push occurs, each script runs in an isolated environment to determine whether the push is accepted or rejected.

Organization webhooks:

Webhook events are also sent from your repository to your "organization webhooks". more info.

These are set up in your github enterprise. They are specific to the version of the github enterprise. You may have no visibility because of your access limitations (developer, maintainer, admin, etc).

I'm using hub, a tool from github: https://github.com/github/hub

With hub checking out a pull request locally is kinda easy:

hub checkout https://github.com/owner/repo/pull/1234
or
hub pr checkout 1234

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

If you have a handleChange function that looks like this:

handleChange = (e) => {
  this.setState({
    [e.target.name]: e.target.value,
  });
}

You can create a custom onChange function so that it acts like an text input would:

<input
  type="checkbox"
  name="check"
  checked={this.state.check}
  onChange={(e) => {
    this.handleChange({
      target: {
        name: e.target.name,
        value: e.target.checked,
      },
    });
  }}
/>

On a Mac, you need to use this command:

STATIC_DEPS=true sudo pip install lxml

I had a dynamically generated, but badly formed table with a typo. I copied a <td> tag inside another <td> by mistake. My column count matched. I had <thead> and <tbody> tags. Everything matched, except for this little mistake I didn't notice for a while, because my column had a lot of link and image tags in it.

The example below includes scrolling behaviour if the content of the expanded centre component extends past its bounds. Also the centre component takes 100% of remaining space in the viewport.

jsfiddle here

html, body, .r_flex_container{
    height: 100%;
    display: flex;
    flex-direction: column;
    background: red;
    margin: 0;
}
.r_flex_container {
    display:flex;
    flex-flow: column nowrap;
    background-color:blue;
}

.r_flex_fixed_child {
    flex:none;
    background-color:black;
    color:white;

}
.r_flex_expand_child {
    flex:auto;
    background-color:yellow;
    overflow-y:scroll;
}

Example of html that can be used to demonstrate this behaviour

<html>
<body>
    <div class="r_flex_container">
      <div class="r_flex_fixed_child">
        <p> This is the fixed 'header' child of the flex container </p>
      </div>
      <div class="r_flex_expand_child">
            <article>this child container expands to use all of the space given to it -  but could be shared with other expanding childs in which case they would get equal space after the fixed container space is allocated.

i Solve My Problem Through this Method

You should also be able to do:

apt install sudo

sudo -i -u tomcat

Then you should be the tomcat user. It's not clear which Linux distribution you're using, but this works with Ubuntu 18.04 LTS, for example.

You need to input:

$ git pull
$ git fetch 
$ git merge

If you use a git push origin master --force, you will have a big problem.

In my case closing of editor (visual studio code) solved a problem.

yet another go at the same problem - form-container on npm

Just do:

ng-click="prefs = false"

Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

An earlier process of resolving conflicts (through the staging view) in Eclipse seemed much more intuitive several years ago, so either the tooling no longer functions in the way that I was used to, or I am remembering the process of resolving merge conflicts within SVN repositories. Regardless, there was this nifty "Mark as Merged" menu option when right-clicking on a conflicting file.

Fast forward to 2019, I am using the "Git Staging" view in Eclipse (v4.11). Actually, I am using STS (Spring Tool Suite 3.9.8), but I think the Git Staging view is a standard Eclipse plugin for working with Java/Spring-based projects. I share the following approach in case it helps anyone else, and because I grow weary or resolving merge conflicts from the GIT command line. ;-)

Because the feature I recall is now gone (or perhaps done differently with the current version of GIT and Eclipse), here are the current steps that I now follow to resolve merge conflicts through Eclipse using a GIT repository. It seems the most intuitive to me. Obviously, it is clear from the number of responses here that there are many ways to resolve merge conflicts. Perhaps I just need to switch to JetBrains IntelliJ, with their three-way merge tool.

1. Double-click on the offending file
2. A "Text Compare" interface appears, with side-by-side views of the conflicting commits.
3. Identify which view is the local state of the file, or the most recent commit.
4. Make changes to the local window, either adding or redacting the changes from the offending commit.
5. When the desired set of changes has been reviewed and updated, right-click on the unstaged file.
6. Click the "Add to Index" option, and your file will be added to the staged changes.
7. This also removes the conflicting file from the unstaged list, thus indicating that it has been "marked as merged"
8. Continue this process with each additional file in conflict.
9. When you have reivewed all conflicting files, confirm that all desired files (including additional changes) are staged.
10. Add an appropriate commit message.
11. Commit and push the "merged" files to the origin repository, and this officially marks your files as merged.

NOTE: Because the menu options are not intuitive, a number of things can be misleading. For example, if you have saved any updates locally, and try to reopen the conflicting file to confirmand that the changes you made have persisted, confusion may result since the original conflict state is opened... not your changes.

But once you add the file(s) to the index, you will see your changes there.

I also recommend that when you pull in changes that result in a merge conflict, that you "stash" your local changes first, and then pull the changes in again. At least with GIT, as a protection, you will not be allowed to pull in external changes until you either revert your changes or stash them. Discard and revert to the HEAD state if the changes are not important, but stash them otherwise.

Finally, if you have just one or two files changing, then consider pulling them into separate text files as a reference, then revert to the HEAD and then manually update the file(s) when you pull changes across.

You can put all your #m1...#m9 divs into .target and display them based on fragment identifier (hash) using :target pseudo-class. It doesn't move the contents between divs, but I think the effect is close to what you wanted to achieve.

Fiddle

HTML

<div class="target">
    <div id="m1">
        dasdasdasd m1
    </div>
    <!-- etc... -->
    <div id="m9">
        dasdasdsgaswa m9
    </div>   
</div>

CSS

.target {
    width:50%;
    height:200px;
    border:solid black 1px; 
}
.target > div {
    display:none;
}

.target > div:target{
    display:block;
}

Based on the error message, your problem seems to be related to interpolation (typically your expression {{}}), not to a cross-domain issue. Basically ng-src="{{object.src}}" sucks.

ng-src was designed with img tag in mind IMO. It might not be appropriate for <source>. See http://docs.angularjs.org/api/ng.directive:ngSrc

If you declare <source src="somesite.com/myvideo.mp4"; type="video/mp4"/>, it will be working, right? (note that I remove ng-src in favor of src) If not it must be fixed first.

Then ensure that {{object.src}} returns the expected value (outside of <video>):

<span>{{object.src}}</span>
<video>...</video>

If it returns the expected value, the following statement should be working:

<source src="{{object.src}}"; type="video/mp4"/> //src instead of ng-src

For a new repository, the method works for me:

1. Remote the files related with git
   rm -rf .git

2. Do the commit again
   git add . && git commit -m "your commit"

3. Add the git URL and try to push again
   git remote add origin <your git URL>

4. And then try to push again
   git push -u origin master -f

5. Success!

Since it's a new repository, so it doesn't matter for me to remove the git and add it again.

I solved my problem with adding these in build gradle:

   defaultConfig {
   multiDexEnabled true


 dependencies {
 compile 'com.android.support:multidex:1.0.0'

another solution can be removing unnecessary libraries

I started getting this error when upgrading to ButterKnife 8.5.1. None of the other answers here worked for me.

I used gradle -q :app:dependencies to see the tree, and then looked through jar files until I found the conflict. The conflict was that butterknife's dependency on com.android.support:support-compat:25.1.0 contains a version of the accessibility class, and com.android.support:support-v4:23.1.1 also contains the class.

I solved it by changing my dependency from this:

compile 'com.jakewharton:butterknife:8.5.1'

to this:

compile('com.jakewharton:butterknife:8.5.1') {
    exclude module: 'support-compat'
}

It doesn't seem to affect ButterKnife's operation so far.

Edit: There is a better solution, which was to upgrade my android support libraries to match ButterKnife's:

compile('com.android.support:appcompat-v7:25.2.0')
compile('com.android.support:design:25.2.0')
compile 'com.jakewharton:butterknife:8.5.1'

This error occurs when you push the data from your local directory to your remote git repository by following git command: git push -u origin master

As local directory and git remote directory's files conflicted.

Solution :

After committing all files to staging follow below steps.

1. Fetch the files from the remote repository as its conflict with the local working directory.

   • git pull <remoter-url> <branch-name>

2. Commit the changes again.

   • git add -A
   • git commit -m ‘<comment>'

3. After committed merge files with both directory you can use

   • git push -u origin master

This will fix the issue. Thanks.

I had similar problems with phpMyAdmin after changing Mysql InnoDB setting to innodb_file_per_table = 1
to move InnoDB tables into separate files.

None of the other answers helped in my case, neither sudo dpkg-reconfigure phpmyadmin nor importing create_tables.sql. Both failed.

What helped was making sure no default-storage-engine, default-tmp-storage-engine and innodb_file_format is enforced in my.cnf

After restarting MySQL and removing+reinstalling phpMyAdmin there are no more errors.

Removing .txt after LICENSE removed my error :

packagingOptions {
    exclude 'META-INF/LICENSE'
}

In Eclipse do the following:

GIT Repositories > Remotes > Origin > Right click and say fetch

GIT Repositories > Remote Tracking > Select your branch and say merge

Go to project, right click on your file and say Fetch from upstream.

I was getting similar errors and eventually found just that cleaning the build folder resolved my issue.

mvn clean install

I don't blame you for getting frustrated about this. The best way to look at is this. There are potentially three versions of every remote branch:

1. The actual branch on the remote repository
   (e.g., remote repo at https://example.com/repo.git, refs/heads/master)
2. Your snapshot of that branch locally (stored under refs/remotes/...)
   (e.g., local repo, refs/remotes/origin/master)
3. And a local branch that might be tracking the remote branch
   (e.g., local repo, refs/heads/master)

Let's start with git prune. This removes objects that are no longer being referenced, it does not remove references. In your case, you have a local branch. That means there's a ref named random_branch_I_want_deleted that refers to some objects that represent the history of that branch. So, by definition, git prune will not remove random_branch_I_want_deleted. Really, git prune is a way to delete data that has accumulated in Git but is not being referenced by anything. In general, it doesn't affect your view of any branches.

git remote prune origin and git fetch --prune both operate on references under refs/remotes/... (I'll refer to these as remote references). It doesn't affect local branches. The git remote version is useful if you only want to remove remote references under a particular remote. Otherwise, the two do exactly the same thing. So, in short, git remote prune and git fetch --prune operate on number 2 above. For example, if you deleted a branch using the git web GUI and don't want it to show up in your local branch list anymore (git branch -r), then this is the command you should use.

To remove a local branch, you should use git branch -d (or -D if it's not merged anywhere). FWIW, there is no git command to automatically remove the local tracking branches if a remote branch disappears.

I set the column widths in the HTML markup like so:

    <thead>
        <tr>

            <th style='width: 5%;'>ProjectId</th>
            <th style='width: 15%;'>Title</th>
            <th style='width: 40%;'>Abstract</th>
            <th style='width: 20%;'>Keywords</th>
            <th style='width: 10%;'>PaperName</th>
            <th style='width: 10%;'>PaperURL</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr id="@item.ID">
                <td>@item.ProjectId</td>
                <td>@item.Title</td>
                <td>@item.Abstract</td>
                <td>@item.Keywords</td>
                <td>@item.PaperName</td>
                <td>@item.PaperURL</td>
            </tr>
        }
    </tbody>
</table>

In Windows SourceTree, untick Push all tags to remotes.

Adding a category to UIColor the following way will make it available to you anytime you need it or even change its definition accross your code:

@interface UIColor (iOS7Colors)

+ (instancetype)iOS7blueColor;

@end

@implementation UIColor (SpecialColors)

+ (instancetype)iOS7blueColor;
{
    return [UIColor colorWithRed:0.0f green:0.22f blue:122.0/255.0 alpha:1.0f];
}

Once you import the Category in your code you can call the color by using:

UIColor *myBlueColor = [UIColor iOSblueColor];

For people using Tiny Core Linux, you also need to install libtool-dev as it has the *.m4 files needed for libtoolize.

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

I kept using this all this time

Import-module .\build_functions.ps1 -Force

I wanted to add this as a comment under Zoey Hewil's awesome answer above, but I don't currently have enough rep to do so, so I have to add it here and give credit for her work :P

If you're using Poshgit and are feeling exceptionally lazy, you can use the following to automatically extract your URL from your git config and make an easy job even easier. Standard caveats apply about testing this on a copy/backing up your local repo first in case it blows up in your face.

$config = get-content .git\config
$url = $config -match " url = (?<content>.*)"
$url = $url.trim().Substring(6)
$url

move-item -v .git .git_old;
git init;
git remote add origin "$url";
git fetch;
git reset origin/master --mixed

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

On ubuntu, try dpkg-reconfigure phpmyadmin and recreate the phpmyadmin database. I installed using ansible and this was not done.

You can create a custom alertDialog and use a xml layout. in the layout, you can set the background color and textcolor.

Something like this:

Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
LayoutInflater inflater = (LayoutInflater)ActivityName.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_layout,(ViewGroup)findViewById(R.id.layout_root));
dialog.setContentView(view);

Microsoft is releasing the "Microsoft Edge WebView2" WPF control that will get us a great, free option for embedding Chromium across Windows 10, Windows 8.1, or Windows 7. It is available via Nuget as the package Microsoft.Web.WebView2.

I had the same problem, you should do:

File -> Invalidate Caches / Restart

First, you can make sure to use the proper url:

git remote set-url origin https://github.com/zkirkland/Random-Python-Tests.git

Then, if it was working before, and if it wasn't asking for you username, it must be because you had stored your credentials (login/password) in a $HOME/.netrc file, as explained here. You can double-check those settings, and make sure that your proxy, if you have one, hasn't changed.

If that still doesn't work, you can switch to an ssh url:

git remote set-url origin [email protected]:zkirkland/Random-Python-Tests.git

But that means you have published your ssh public key in your Account settings.

You do not include a <scope> tag in your dependency. If you add it, your dependency becomes something like:

<dependency>
     <groupId>org.openrdf.sesame</groupId>
     <artifactId>sesame-runtime</artifactId>
     <version>2.7.2</version>
     <scope> ... </scope>
</dependency>

The "scope" tag tells maven at which stage of the build your dependency is needed. Examples for the values to put inside are "test", "provided" or "runtime" (omit the quotes in your pom). I do not know your dependency so I cannot tell you what value to choose. Please consult the Maven documentation and the documentation of your dependency.

You should be able to accomplish this by adding a refspec for tags to your local config. Concretely:

[remote "upstream"]
    url = <redacted>
    fetch = +refs/heads/*:refs/remotes/upstream/*
    fetch = +refs/tags/*:refs/tags/*

If someone is using the new DataTables (which is awesome btw) and want to use array of objects then you can do so easily with the columns option. Refer to the following link for an excellent example on this.

DataTables with Array of Objects

I was struggling with this for the past 2 days and this solved it. I didn't wanted to switch to multi-dimensional arrays for other code reasons so was looking for a solution like this.

I found very good link for JSON: http://code.google.com/p/json-simple/wiki/EncodingExamples#Example_1-1_-_Encode_a_JSON_object

Here's code to add multiple JSONObjects to JSONArray.

JSONArray Obj = new JSONArray();
try {
    for(int i = 0; i < 3; i++) {
        // 1st object
        JSONObject list1 = new JSONObject();
        list1.put("val1",i+1);
        list1.put("val2",i+2);
        list1.put("val3",i+3);
        obj.put(list1);
    }

} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}             
Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();

This is actually a JDK bug. It has been reported several times over the years, but only in 8139507 was it finally taken seriously by Oracle.

The problem was in the JDK source code for WindowsPreferences.java. In this class, both nodes userRoot and systemRoot were declared static as in:

/**
 * User root node.
 */
static final Preferences userRoot =
     new WindowsPreferences(USER_ROOT_NATIVE_HANDLE, WINDOWS_ROOT_PATH);

/**
 * System root node.
 */
static final Preferences systemRoot =
    new WindowsPreferences(SYSTEM_ROOT_NATIVE_HANDLE, WINDOWS_ROOT_PATH);

This means that the first time the class is referenced both static variables would be initiated and by this the Registry Key for HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs (= system tree) will be attempted to be created if it doesn't already exist.

So even if the user took every precaution in his own code and never touched or referenced the system tree, then the JVM would actually still try to instantiate systemRoot, thus causing the warning. It is an interesting subtle bug.

There's a fix committed to the JDK source in June 2016 and it is part of Java9 onwards. There's also a backport for Java8 which is in u202.

What you see is really a warning from the JDK's internal logger. It is not an exception. I believe that the warning can be safely ignored .... unless the user code is indeed wanting the system preferences, but that is very rarely the case.

Bonus info

The bug did not reveal itself in versions prior to Java 1.7.21, because up until then the JRE installer would create Registry key HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs for you and this would effectively hide the bug. On the other hand you've never really been required to run an installer in order to have a JRE on your machine, or at least this hasn't been Sun/Oracle's intent. As you may be aware Oracle has been distributing the JRE for Windows in .tar.gz format for many years.

Try to create remote origin first, maybe is missing because you change name of the remote repo

git remote add origin URL_TO_YOUR_REPO

Do npm install npm@latest -g to update npm to the latest version. This fixed the problem for me. I did do npm cache clean first

In my case, Git is using Windows to store credentials.

All you have to do is remove the stored credentials stored in your Windows account:

I was designing a GUI in SceneBuilder, trying to make the main container adapt to whatever the window size is. It should always be 100% wide.

This is where you can set these values in SceneBuilder:

Toggling the dotted/red lines will actually just add/remove the attributes that Korki posted in his solution (AnchorPane.topAnchor etc.).

I ran into a similar issue where eclipse was not using my current %JAVA_HOME% that was on the path and was instead using an older version. The documentation points out that if no -vm is specified in the ini file, eclipse will search for a shared library jvm.dll This appears in the registry under the key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment that gets installed when using the windows java installer (key might be a bit different based on 64-bit vs 32-bit, but search for jvm.dll). Because it was finding this shared library on my path before the %JAVA_HOME%/bin, it was using the old version.

Like others have stated, the easiest way to deal with this is to specify the specific vm you want to use in the eclipse.ini file. I'm writing this because I couldn't figure out how it was still using the old version when it wasn't specified anywhere on the path or eclipse.ini file.

See link to doc below: http://help.eclipse.org/kepler/topic/org.eclipse.platform.doc.isv/reference/misc/launcher.html?cp=2_1_3_1

Finding a VM and using the JNI Invocation API

The Eclipse launcher is capable of loading the Java VM in the eclipse process using the Java Native Interface Invocation API. The launcher is still capable of starting the Java VM in a separate process the same as previous version of Eclipse did. Which method is used depends on how the VM was found.

No -vm specified

When no -vm is specified, the launcher looks for a virtual machine first in a jre directory in the root of eclipse and then on the search path. If java is found in either location, then the launcher looks for a jvm shared library (jvm.dll on Windows, libjvm.so on *nix platforms) relative to that java executable.

• If a jvm shared library is found the launcher loads it and uses the JNI invocation API to start the vm.
• If no jvm shared library is found, the launcher executes the java launcher to start the vm in a new process.

-vm specified on the command line or in eclipse.ini

Eclipse can be started with "-vm " to indicate a virtual machine to use. There are several possibilities for the value of :

• directory: is a directory. We look in that directory for:
  • (1) a java launcher or
  • (2) the jvm shared library.

If we find the jvm shared library, we use JNI invocation. If we find a launcher, we attempt to find a jvm library in known locations relative to the launcher. If we find one, we use JNI invocation. If no jvm library is found, we exec java in a new process.

• java.exe/javaw.exe: is a path to a java launcher. We exec that java launcher to start the vm in a new process.

• jvm dll or so: is a path to a jvm shared library. We attempt to load that library and use the JNI Invocation API to start the vm in the current process.

In my situation, we are using Git Flow and GitHub. All you need to do this is: Compare your feature branch with your develop branch on GitHub.

It will show the commits only made to your feature branch.

For example:

https://github.com/your_repo/compare/develop...feature_branch_name

It doesn't because the href value is not sign_up.It is #sign_up. Try like below, You need to add "#" to indicate the id of the href value.

$('a[href="#sign_up"]').click(function(){
  alert('Sign new href executed.'); 
}); 

DEMO: http://jsfiddle.net/pnGbP/

Assuming the expectation is just going to be two windows popping up (one of the parent and one for the popup) then just wait for two windows to come up, find the other window handle and switch to it.

WebElement link = // element that will showModalDialog()

// Click on the link, but don't wait for the document to finish
final JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript(
    "var el=arguments[0]; setTimeout(function() { el.click(); }, 100);",
  link);

// wait for there to be two windows and choose the one that is 
// not the original window
final String parentWindowHandle = driver.getWindowHandle();
new WebDriverWait(driver, 60, 1000)
    .until(new Function<WebDriver, Boolean>() {
    @Override
    public Boolean apply(final WebDriver driver) {
        final String[] windowHandles =
            driver.getWindowHandles().toArray(new String[0]);
        if (windowHandles.length != 2) {
            return false;
        }
        if (windowHandles[0].equals(parentWindowHandle)) {
            driver.switchTo().window(windowHandles[1]);
        } else {
            driver.switchTo().window(windowHandles[0]);
        }
        return true;
    }
});

if you just type

$ git update

on bash git will inform you that 'update' command is no longer working and will display the correct command which is 'update-git-for-windows'

but still the update will continue you just have to press " y "

if you are having issues on it run the bashh as administrator or add the 'git.exe' path to the "allowed apps through controlled folder access".

Go to MINGW32 terminal put this Command : git branch --set-upstream-to=origin/(branch Name)

It would seem like your user doesn't have permission to write to that directory on the server. Please make sure that the permissions are correct. The user will need write permissions on that directory.

It sounds trivial, but my issue was that I wasn't in the right project. Make sure you are in the project you expect to be in; otherwise, you won't be able to pull down the correct branches.

I shear the point made by user2237829. The table names in the create_tables script used a double underscore while the table names in the xampp example uses a single underscore.

As JERC said, make sure you have an updated version of git. If you are only using the default settings, when you try to install git you will get version 1.7.1. Other than manually downloading and installing the latest version of get, you can also accomplish this by adding a new repository to yum.

From tecadmin.net:

Download and install the rpmforge repository:

# use this for 64-bit
rpm -i 'http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm'
# use this for 32-bit
rpm -i 'http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.i686.rpm'

# then run this in either case
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

Then you need to enable the rpmforge-extras. Edit /etc/yum.repos.d/rpmforge.repo and change enabled = 0 to enabled = 1 under [rpmforge-extras]. The file looks like this:

### Name: RPMforge RPM Repository for RHEL 6 - dag
### URL: http://rpmforge.net/
[rpmforge]
name = RHEL $releasever - RPMforge.net - dag
baseurl = http://apt.sw.be/redhat/el6/en/$basearch/rpmforge
mirrorlist = http://mirrorlist.repoforge.org/el6/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

[rpmforge-extras]
name = RHEL $releasever - RPMforge.net - extras
baseurl = http://apt.sw.be/redhat/el6/en/$basearch/extras
mirrorlist = http://mirrorlist.repoforge.org/el6/mirrors-rpmforge-extras
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-extras
enabled = 0 ####### CHANGE THIS LINE TO "enabled = 1" #############
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

[rpmforge-testing]
name = RHEL $releasever - RPMforge.net - testing
baseurl = http://apt.sw.be/redhat/el6/en/$basearch/testing
mirrorlist = http://mirrorlist.repoforge.org/el6/mirrors-rpmforge-testing
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-testing
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

Once you've done this, then you can update git with

yum update git

I'm not sure why, but they then suggest disabling rpmforge-extras (change back to enabled = 0) and then running yum clean all.

Most likely you'll need to use sudo for these commands.

It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.

To create a master branch:

git checkout -b master

And you can work off of that.

If you clone with the --depth parameter, it sets .git/config not to fetch all branches, but only master.

You can simply omit the parameter or update the configuration file from

fetch = +refs/heads/master:refs/remotes/origin/master

to

fetch = +refs/heads/*:refs/remotes/origin/*

As explained in "Deleting your master branch" by Matthew Brett, you need to change your GitHub repo default branch.

You need to go to the GitHub page for your forked repository, and click on the “Settings” button.

Click on the "Branches" tab on the left hand side. There’s a “Default branch” dropdown list near the top of the screen.

From there, select placeholder (where placeholder is the dummy name for your new default branch).

Confirm that you want to change your default branch.

Now you can do (from the command line):

git push origin :master

Or, since 2012, you can delete that same branch directly on GitHub:

That was announced in Sept. 2013, a year after I initially wrote that answer.

For small changes like documentation fixes, typos, or if you’re just a walking software compiler, you can get a lot done in your browser without needing to clone the entire repository to your computer.

Note: for BitBucket, Tum reports in the comments:

About the same for Bitbucket

Repo -> Settings -> Repository details -> Main branch

Your list:

List<MyCustomObject> myCustomObjectList;

Your JSONArray:

// Don't need to loop through it. JSONArray constructor do it for you.
new JSONArray(myCustomObjectList)

Your response:

return new JSONObject().put("yourCustomKey", new JSONArray(myCustomObjectList));

Your post/put http body request would be like this:

    {
        "yourCustomKey: [
           {
               "myCustomObjectProperty": 1
           },
           {
               "myCustomObjectProperty": 2
           }
        ]
    }

Add

"aaSorting": []

And check if default value is not null only set sortable column then

if ($('#table').DataTable().order().length == 1) {
    d.SortColumn = $('#table').DataTable().order()[0][0];
    d.SortOrder = $('#table').DataTable().order()[0][1];
}

I encountered the same issue with CSS on a live environment. I followed all of the advise here and investigated how the bundling works behind the scene. This lead me to request that the .Net cache was cleared (I didn't have access to the app servers) which caused the bundling to start working on the app servers. However, when accessing the site via a load balancer with a CDN configured, although the bundle identifier was updated in the url, the bundle contained the old CSS. Simply flushing the CDN resolved the issue.

I hope this goes some way to helping some one else who may encounter this

Permanent Fix

git update-ref -d resolved my instance of this error, e.g.

git update-ref -d refs/remotes/origin/user

Note that this doesn't impact remote.

In my case, a subsequent git fetch fetched that branch again, and following git fetches/pulls no longer gave the error "remote ref is at but expected".

If that doesn't work, a temporary fix:

Note also that if you don't care about the branch in question (e.g. you just want to update master, not origin/user), a git pull workaround is to fetch then just merge the particular branch you care about, e.g.

git fetch # may give an error for a particular branch, but other branches will still be successfully fetched
git merge origin/master

Try this command: "git pull origin master"

It worked for me.

Check this link: https://help.github.com/articles/dealing-with-non-fast-forward-errors

In order to have this result:

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

that holds the same data as:

  {
    "aoColumnDefs": [
     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
   ]
  }

you could use this code:

    JSONObject jo = new JSONObject();
    Collection<JSONObject> items = new ArrayList<JSONObject>();

    JSONObject item1 = new JSONObject();
    item1.put("aDataSort", new JSONArray(0, 1));
    item1.put("aTargets", new JSONArray(0));
    items.add(item1);
    JSONObject item2 = new JSONObject();
    item2.put("aDataSort", new JSONArray(1, 0));
    item2.put("aTargets", new JSONArray(1));
    items.add(item2);
    JSONObject item3 = new JSONObject();
    item3.put("aDataSort", new JSONArray(2, 3, 4));
    item3.put("aTargets", new JSONArray(2));
    items.add(item3);

    jo.put("aoColumnDefs", new JSONArray(items));

    System.out.println(jo.toString());

I got this error when I was playing around while reading progit. I made a local repository, then fetched it in another repo on the same file system, made an edit and tried to push. After reading NowhereMan's answer, a quick fix was to go to the "remote" directory and temporarily checkout another commit, push from the directory I made changes in, then go back and put the head back on master.

Your origin repository is ahead of your local repository. You'll need to pull down changes from the origin repository as follows before you can push. This can be executed between your commit and push.

git pull origin development

development refers to the branch you want to pull from. If you want to pull from master branch then type this one.

git pull origin master

I made my own custom imageview with pinch to zoom. There is no limits/borders on Chirag Ravals code, so user can drag the image off the screen. This will fix it.

This is how you can use it in your activity:

CustomImageVIew mImageView = (CustomImageVIew)findViewById(R.id.customImageVIew1);
mImage.setBitmap(your bitmap);

And layout:

<your.package.name.CustomImageVIew
        android:id="@+id/customImageVIew1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_marginBottom="15dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:layout_marginTop="15dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" 
        android:scaleType="matrix"/> // important

In order to avoid having to fully specify the git push command you could alternatively modify your git config file:

[remote "gerrit"]
    url = https://your.gerrit.repo:44444/repo
    fetch = +refs/heads/master:refs/remotes/origin/master
    push = refs/heads/master:refs/for/master

Now you can simply:

git fetch gerrit
git push gerrit

This is according to Gerrit

Setting 'clang' as the compiler configure should use worked for me:

export CC=clang
pip install --no-clean pycrypto

Just had the same issue but in my case I had typed the wrong branch on the remote. So, it seems that is another source of this issue... double check you're pushing to the correct branch.

You can replace the src/main/resources/ directly by classpath:

So for your example you will replace this line:

new BufferedReader(new FileReader(new File("src/main/resources/config.txt")));

By this line:

new BufferedReader(new FileReader(new File("classpath:config.txt")));

Speaking from a PC user - Reboot.

Honestly, it worked for me. I've solved two strange git issues I thought were corruptions this way.

If you are here to copy-paste code:

This is an example which removes node_modules from history

git filter-branch --tree-filter "rm -rf node_modules" --prune-empty HEAD
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force

What git actually does:

The first line iterates through all references on the same tree (--tree-filter) as HEAD (your current branch), running the command rm -rf node_modules. This command deletes the node_modules folder (-r, without -r, rm won't delete folders), with no prompt given to the user (-f). The added --prune-empty deletes useless (not changing anything) commits recursively.

The second line deletes the reference to that old branch.

The rest of the commands are relatively straightforward.

I did the following steps to resolve the issue. On the branch which was giving me the error:

1. git pull origin [branch-name]<current branch>
2. After pulling, got some merge issues, solved them, pushed the changes to the same branch.
3. Created the Pull request with the pushed branch... tada, My changes were reflecting, all of them.

for me deleting package-lock.json fixed my problem,

1. delete
2. commit changes
3. push again

turns out Heroku accepts only one package.json file :p

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?

The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)

In my case I had forgotten to use postgres in my production environment. I moved the sqlite3 gem into my development and test groups in my Gemfile. Everything worked after that.

I came across an amazing resource on css-tricks: https://css-tricks.com/using-svg/

There are a handful of solutions explained there.

I preferred the one that required minimal edits to the source svg, and also didn't require it to be embedded into the html document. This option utilizes the <object> tag.

Add the svg file into your html using <object>; I also declared html attributes width and height. Using these width and heights the svg document does not get scaled, I worked around that using a css transform: scale(...) statement for the svg tag in my associated svg css file.

<object type="image/svg+xml" data="myfile.svg" width="64" height="64"></object>

Create a css file to attach to your svn document. My source svg path was scaled to 16px, I upscaled it to 64 with a factor of four. It only had one path so I did not need to select it more specifically, however the path had a fill attribute so I had to use !IMPORTANT to force the css to take precedent.

#svg2 {
    width: 64px; height: 64px;
    transform: scale(4);
}
path {
    fill: #333 !IMPORTANT;
}

Edit your target svg file, before the opening <svg tag, to include a stylesheet; Note that the href is relative to the svg file url.

<?xml-stylesheet type="text/css" href="myfile.css" ?>

Correct me if I am wrong, but it seems that Facebook deprecated the Activity Feed plugin. Additionally there does not seem to be any substitute plugin for activity anymore.

Here is the link: https://developers.facebook.com/docs/plugins/activity

You have set a fixed width and height in your svg tag. This is probably the root of your problem. Try not removing those and set the width and height (if needed) using CSS instead.

If you need to add Change-Id to multiple commits, you can download the hook from your Gerrit server and run these commands to add the Change-Ids to all commits that need them at once. The example below fixes all commits on your current branch that have not yet been pushed to the upstream branch.

tmp=$(mktemp)
hook=$(readlink -f $(git rev-parse --git-dir))/hooks/commit-msg
git filter-branch -f --msg-filter "cat > $tmp; \"$hook\" $tmp; cat $tmp" @{u}..HEAD

I cloned the repository with HTTPS URL instead of SSH URL hence even after adding the SSH Key it was asking me for password on Bash Shell.

I just edited the ./.git/config file and changed the value of url variable by simply replacing the https:// to ssh://

E.g.

[core]
        ...
        ...
        ...
[remote "origin"]
        url = https://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

Changed to:

[core]
        ...
        ...
        ...
[remote "origin"]
        url = ssh://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

I wanted to open the Bluetooth Menu in the Settings Application and the above path (prefs:root=General&path=Bluetooth) didn't work for me. What ended up working for me was

UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=Bluetooth")!)

Make sure you have the prefs URL Scheme defined first.

If you want to pull a particular file from another branch just do

git checkout branch1 -- filenamefoo.txt

This will pull a version of the file from one branch into the current tree

Remove the protected branch option or allow additional roles like developers or admins to allow these users experiencing this error to do merges and push.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

On more reason could be e-mail verification on github.com

Just log in to github.com and check if there is no message for you, to confirm your e-mail address. Confirm, if necessary.

Git has two types of branches: local and remote. To use git pull and git push as you'd like, you have to tell your local branch (my_test) which remote branch it's tracking. In typical Git fashion this can be done in both the config file and with commands.

Commands

Make sure you're on your master branch with

1)git checkout master

then create the new branch with

2)git branch --track my_test origin/my_test

and check it out with

3)git checkout my_test.

You can then push and pull without specifying which local and remote.

However if you've already created the branch then you can use the -u switch to tell git's push and pull you'd like to use the specified local and remote branches from now on, like so:

git pull -u my_test origin/my_test
git push -u my_test origin/my_test

Config

The commands to setup remote branch tracking are fairly straight forward but I'm listing the config way as well as I find it easier if I'm setting up a bunch of tracking branches. Using your favourite editor open up your project's .git/config and add the following to the bottom.

[remote "origin"]
    url = [email protected]:username/repo.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "my_test"]
    remote = origin
    merge = refs/heads/my_test

This specifies a remote called origin, in this case a GitHub style one, and then tells the branch my_test to use it as it's remote.

You can find something very similar to this in the config after running the commands above.

Some useful resources:

• http://www.kernel.org/pub/software/scm/git/docs/git-branch.html
• http://gitready.com/beginner/2009/03/09/remote-tracking-branches.html

If you want to store the whole Object that you get in response, It can achieve by doing something like,

First Create a method that converts your JSON into a string in your util class as below.

 public static <T> T fromJson(String jsonString, Class<T> theClass) {
    return new Gson().fromJson(jsonString, theClass);
}

Then In Shared Preferences Class Do something like,

 public void storeLoginResponse(yourResponseClass objName) {

    String loginJSON = UtilClass.toJson(customer);
    if (!TextUtils.isEmpty(customerJSON)) {
        editor.putString(AppConst.PREF_CUSTOMER, customerJSON);
        editor.commit();
    }
}

and then create a method for getPreferences

public Customer getCustomerDetails() {
    String customerDetail = pref.getString(AppConst.PREF_CUSTOMER, null);
    if (!TextUtils.isEmpty(customerDetail)) {
        return GSONConverter.fromJson(customerDetail, Customer.class);
    } else {
        return new Customer();
    }
}

Then Just call the First method when you get response and second when you need to get data from share preferences like

String token = SharedPrefHelper.get().getCustomerDetails().getAccessToken();

that's all.

Hope it will help you.

Happy Coding();

brew install imagemagick

Don't forget to install also gs which is a dependency if you want to convert pdf to images for example :

brew install ghostscript

I had the same issue. But in my case it was due to my branch's name. The branch's name automatically set in my GitHub repo as main instead of master.

git pull origin master (did not work).

I confirmed in GitHub if the name of the branch was actually master and found the the actual name was main. so the commands below worked for me. git pull origin main

You can do something like this:

<html>
<head><title>My Glossary</title></head>
<body style="margin:0px;">
        <div id="top" style="position:fixed;background:white;width:100%;">
            <a href="#A">A</a> |
             <a href="#B">B</a> |
            <a href="#Z">Z</a>
        </div>

        <div id="term-defs" style="padding-top:1em;">
           <dl>
               <span id="A"></span>
               <dt>foo</dt>
               <dd>This is the sound made by a fool</dd>
               <!-- and so on ... ->
           </dl>
        </div>
</body>
</html>

It's the position:fixed that's most important, because it takes the top div from the normal page flow and fixes it at it's pre-determined position. It's also important to use the padding-top:1em because otherwise the term-defs div would start right under the top div. The background and width are there to cover the contents of the term-defs div as they scroll under the top div.

Hope this helps.

Check that you (git process actually) have access to file .git/info/refs and this file isn't locked by another process.

With the Process Phoenix library. The Activity you want to relaunch is named "A".

Java flavor

// Java
public void restart(){
    ProcessPhoenix.triggerRebirth(context);
}

Kotlin flavor

// kotlin
fun restart() {
    ProcessPhoenix.triggerRebirth(context)
}

Since you're on Ubuntu, don't bother with those source packages. Just install those development packages using apt-get.

apt-get install libxml2-dev libxslt1-dev python-dev

If you're happy with a possibly older version of lxml altogether though, you could try

apt-get install python-lxml

and be done with it. :)

yum install python-devel will work.

If yum doesn't work then use

apt-get install python-dev

Because you rebased feature on top of the new master, your local feature is not a fast-forward of origin/feature anymore. So, I think, it's perfectly fine in this case to override the fast-forward check by doing git push origin +feature. You can also specify this in your config

git config remote.origin.push +refs/heads/feature:refs/heads/feature

If other people work on top of origin/feature, they will be disturbed by this forced update. You can avoid that by merging in the new master into feature instead of rebasing. The result will indeed be a fast-forward.

Lets assume your broadcastReceiver is defined like this:

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        // your code

    }
};

If you are using LocalBroadcast in an Activity, then this is how you'll unregister:

LocalBroadcastManager.getInstance(this).unregisterReceiver(broadcastReceiver);

If you are using LocalBroadcast in a Fragment, then this is how you'll unregister:

LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(broadcastReceiver);

If you are using normal broadcast in an Activity, then this is how you'll unregister:

unregisterReceiver(broadcastReceiver);

If you are using normal broadcast in a Fragment, then this is how you'll unregister:

getActivity().unregisterReceiver(broadcastReceiver);

Try this in your alice repository (before pushing):

git config push.default tracking

Or, configure it as the default for your user with git config --global ….

git push does default to the origin repository (which is normally the repository from which you cloned the current repository), but it does not default to pushing the current branch—it defaults to pushing only branches that exist in both the source repository and the destination repository.

The push.default configuration variable (see git-config(1)) controls what git push will push when it is not given any “refspec” arguments (i.e. something after a repository name). The default value gives the behavior described above.

Here are possible values for push.default:

• nothing
  This forces you to supply a “refspec”.

• matching (the default)
  This pushes all branches that exist in both the source repository and the destination repository.
  This is completely independent of the branch that is currently checked out.

• upstream or tracking
  (Both values mean the same thing. The later was deprecated to avoid confusion with “remote-tracking” branches. The former was introduced in 1.7.4.2, so you will have to use the latter if you are using Git 1.7.3.1.)
  These push the current branch to the branch specified by its “upstream” configuration.

• current
  This pushes the current branch to the branch of the same name at the destination repository.

  These last two end up being the same for common cases (e.g. working on local master which uses origin/master as its upstream), but they are different when the local branch has a different name from its “upstream” branch:

  git checkout master
  # hack, commit, hack, commit
  
  # bug report comes in, we want a fix on master without the above commits
  
  git checkout -b quickfix origin/master  # "upstream" is master on origin
  # fix, commit
  git push
  

  With push.default equal to upstream (or tracking), the push would go to origin’s master branch. When it is equal to current, the push would go to origin’s quickfix branch.

The matching setting will update bare’s master in your scenario once it has been established. To establish it, you could use git push origin master once.

However, the upstream setting (or maybe current) seems like it might be a better match for what you expect to happen, so you might want to try it:

# try it once (in Git 1.7.2 and later)
git -c push.default=upstream push

# configure it for only this repository
git config push.default upstream

# configure it for all repositories that do not override it themselves
git config --global push.default upstream

(Again, if you are still using a Git before 1.7.4.2, you will need to use tracking instead of upstream).

This is the command that you need to execute on the mirror:

git remote update

We use phabricator and don't push using git. I had to create bash alias which works on Linux/mac

vim ~/.bash_aliases

new_branch() {
    git checkout -b "$1"
    git branch --set-upstream-to=origin/master "$1"
}

save

source ~/.bash_aliases
new_branch test #instead of git checkout -b test
git pull

Another case of this: Messing with the __repr__ function of an object where a format() call fails non-transparently.

In our case, we used a @property decorator on the __repr__ and passed that object to a format(). The @property decorator causes the __repr__ object to be turned into a string, which then results in the str object is not callable error.

This worked for me. It discards all local changes and resets it to the last commit.

git reset --hard

The error message clearly says that the default constructor has been deleted implicitly. It even says why: the class contains a non-static, const variable, which would not be initialized by the default ctor.

class X {
    const int x;
};

Since X::x is const, it must be initialized -- but a default ctor wouldn't normally initialize it (because it's a POD type). Therefore, to get a default ctor, you need to define one yourself (and it must initialize x). You can get the same kind of situation with a member that's a reference:

class X { 
    whatever &x;
};

It's probably worth noting that both of these will also disable implicit creation of an assignment operator as well, for essentially the same reason. The implicit assignment operator normally does members-wise assignment, but with a const member or reference member, it can't do that because the member can't be assigned. To make assignment work, you need to write your own assignment operator.

This is why a const member should typically be static -- when you do an assignment, you can't assign the const member anyway. In a typical case all your instances are going to have the same value so they might as well share access to a single variable instead of having lots of copies of a variable that will all have the same value.

It is possible, of course, to create instances with different values though -- you (for example) pass a value when you create the object, so two different objects can have two different values. If, however, you try to do something like swapping them, the const member will retain its original value instead of being swapped.

You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:

 git add a_text_file.txt 

... do:

 git commit -m "Initial commit."

... and those errors should go away.

I have resolved this problem using following steps

1. Remove every file from Git's index.

   git rm --cached -r .

2. Rewrite the Git index to pick up all the new line endings.

   git reset --hard

Note that step 2 may remove your local changes. Solution was part of steps described on git site https://help.github.com/articles/dealing-with-line-endings/

The key is "argument-less git-pull". When you do a git pull from a branch, without specifying a source remote or branch, git looks at the branch.<name>.merge setting to know where to pull from. git push -u sets this information for the branch you're pushing.

To see the difference, let's use a new empty branch:

$ git checkout -b test

First, we push without -u:

$ git push origin test
$ git pull
You asked me to pull without telling me which branch you
want to merge with, and 'branch.test.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
use something like the following in your configuration file:

    [branch "test"]
    remote = <nickname>
    merge = <remote-ref>

    [remote "<nickname>"]
    url = <url>
    fetch = <refspec>

See git-config(1) for details.

Now if we add -u:

$ git push -u origin test
Branch test set up to track remote branch test from origin.
Everything up-to-date
$ git pull
Already up-to-date.

Note that tracking information has been set up so that git pull works as expected without specifying the remote or branch.

Update: Bonus tips:

• As Mark mentions in a comment, in addition to git pull this setting also affects default behavior of git push. If you get in the habit of using -u to capture the remote branch you intend to track, I recommend setting your push.default config value to upstream.
• git push -u <remote> HEAD will push the current branch to a branch of the same name on <remote> (and also set up tracking so you can do git push after that).

On Mac, if you have multiple GitHub logins and are not using SSH, force the correct login by using:

git remote set-url origin https://[email protected]/username/repo-name.git

This also works if you're having issues pushing to a private repository.

Simple Factory Example:

// Factory returns object and ownership
// Caller responsible for deletion.
#include <memory>
class FactoryReleaseOwnership{
  public:
    std::unique_ptr<Foo> createFooInSomeWay(){
      return std::unique_ptr<Foo>(new Foo(some, args));
    }
};

// Factory retains object ownership
// Thus returning a reference.
#include <boost/ptr_container/ptr_vector.hpp>
class FactoryRetainOwnership{
  boost::ptr_vector<Foo>  myFoo;
  public:
    Foo& createFooInSomeWay(){
      // Must take care that factory last longer than all references.
      // Could make myFoo static so it last as long as the application.
      myFoo.push_back(new Foo(some, args));
      return myFoo.back();
    }
};

Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

If you're sane about it, editing the config file's safe enough. If you want to be a little more paranoid, you can use the porcelain command to modify it:

git config branch.master.remote newserver

Of course, if you look at the config before and after, you'll see that it did exactly what you were going to do.

But in your individual case, what I'd do is:

git remote rename origin old-origin
git remote rename new-origin origin

That is, if the new server is going to be the canonical remote, why not call it origin as if you'd originally cloned from it?

Track the remote branch

You can specify the default remote repository for pushing and pulling using git-branch’s track option. You’d normally do this by specifying the --track option when creating your local master branch, but as it already exists we’ll just update the config manually like so:

Edit your .git/config

[branch "master"]
  remote = origin
  merge = refs/heads/master

Now you can simply git push and git pull.

[source]

try using return 0;

if it keeps failing change your solution platform to 64x instead of 86x and go to configuration manager(that's were you change the 86x to 64x) and in platform set it to 64 bits

that works for me, hope it work to you

You can use Path.Combine with the "base" path, then GetFullPath on the results.

string absPathContainingHrefs = GetAbsolutePath(); // Get the "base" path
string fullPath = Path.Combine(absPathContainingHrefs, @"..\..\images\image.jpg");
fullPath = Path.GetFullPath(fullPath);  // Will turn the above into a proper abs path

You need to merge and resolve the conflicts locally before you push your changes to remote repo/fork.

1) pull (fetch and merge)

$ git pull remote branch 

2) Push the changes

$ git push remote branch 

Still you have a quick choice to push forcibly by using --force option but should be avoided as it may result in changes loss or affect badly on other contributors.

For those using Magit, hit l and =m to toggle --no-merges and =pto toggle --first-parent.

Then either just hit l again to show commits from the current branch (with none of commits merged onto it) down to end of history, or, if you want the log to end where it was branched off from master, hit o and type master.. as your range:

Missing or skipping git add . or git commit may cause this error:

git push -u origin master
Username for 'https://github.com': yourusername
Password for 'https://[email protected]': 
error: src refspec master does not match any.
error: failed to push some refs to 'https://github.com/yourusername/foobar.git'

To fix it, reinitialize and follow the proper sequence:

git init
git add .
git commit -m 'message'
git *create remote
git push -u origin master

For pushing a single tag: git push <reponame> <tagname>

For instance, git push production 1.0.0. Tags are not bound to branches, they are bound to commits.

When you want to have the tag's content in the master branch, do that locally on your machine. I would assume that you continued developing in your local master branch. Then just a git push origin master should suffice.

I'd suggest a RelativeLayout instead of a FrameLayout.

Assuming that you want to have the TextView always below the ImageView I'd use following layout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerInParent="true"
        android:src="@drawable/icon"
        android:visibility="visible"/>
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_below="@id/imageview"
        android:gravity="center"
        android:text="@string/hello"/>
</RelativeLayout>

Note that if you set the visibility of an element to gone then the space that element would consume is gone whereas when you use invisible instead the space it'd consume will be preserved.

If you want to have the TextView on top of the ImageView then simply leave out the android:layout_alignParentTop or set it to false and on the TextView leave out the android:layout_below="@id/imageview" attribute. Like this.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:id="@+id/imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="false"
        android:layout_centerInParent="true"
        android:src="@drawable/icon"
        android:visibility="visible"/>
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center"
        android:text="@string/hello"/>
</RelativeLayout>

I hope this is what you were looking for.

In case anyone else is stuck with this: it just means the write permissions are wrong in the repo that you’re pushing to. Go and chmod -R it so that the user you’re accessing the git server with has write access.

It just works.

My issue was resolved After adding
sessionFactory.setPackagesToScan( new String[] { "com.springhibernate.model" }); Tested this Functionality in spring boot latest version 2.1.2.

Full Method:

 @Bean( name="sessionFactoryConfig")
    public LocalSessionFactoryBean sessionFactoryConfig() {

        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

        sessionFactory.setDataSource(dataSourceConfig());
        sessionFactory.setPackagesToScan(
                new String[] { "com.springhibernate.model" });

        sessionFactory.setHibernateProperties(hibernatePropertiesConfig());

        return sessionFactory;
    }

The code will look like this:

$(".data-cash").each(function (index) {
  $(this).dataTable({
    "sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",
    "sPaginationType": "bootstrap",
    "oLanguage": {
      "sLengthMenu": "_MENU_ records per page",
      "oPaginate": {
        "sPrevious": "Prev",
        "sNext": "Next"
      }
    },
    "bSort": false,
    "aaSorting": []
  });
});

It's about the ABI, in order to let both C and C++ application use C interfaces without any issue.

Since C language is very easy, code generation was stable for many years for different compilers, such as GCC, Borland C\C++, MSVC etc.

While C++ becomes more and more popular, a lot things must be added into the new C++ domain (for example finally the Cfront was abandoned at AT&T because C could not cover all the features it needs). Such as template feature, and compilation-time code generation, from the past, the different compiler vendors actually did the actual implementation of C++ compiler and linker separately, the actual ABIs are not compatible at all to the C++ program at different platforms.

People might still like to implement the actual program in C++ but still keep the old C interface and ABI as usual, the header file has to declare extern "C" {}, it tells the compiler generate compatible/old/simple/easy C ABI for the interface functions if the compiler is C compiler not C++ compiler.

On a side note, this issue can happen in Windows if the user who is trying to use git is different than the user who installed it. The error may indicate that git cannot access the certificate files. Installing git as the administrator and using @rogertoday's answer resolved my issue.

Have you checked your time?

I absolutely refused to make my git operations insecure and after trying everything people mentioned here, it struck me that one possible cause why certificates fail to pass verification is that the dates are wrong (either the certificate expiry date, or the local clock).

You can check this easily by typing date in a terminal. In my case (a new raspberry Pi), the local clock was set to 1970, so a simple ntpdate -u 0.ubuntu.pool.ntp.org fixed everything. For a rPi, I would also recommend that you put the following script in a daily cron job (say /etc/cron.daily/ntpdate):

#!/bin/sh
/usr/sbin/ntpdate -u 0.ubuntu.pool.ntp.org 1> /dev/null 2>&1

Try this:

                Grid grid = new Grid(); //Define the grid
                for (int i = 0; i < 36; i++) //Add 36 rows
                {
                    ColumnDefinition columna = new ColumnDefinition()
                    {
                        Name = "Col_" + i,
                        Width = new GridLength(32.5),
                    };
                    grid.ColumnDefinitions.Add(columna);
                }

                for (int i = 0; i < 36; i++) //Add 36 columns
                {
                    RowDefinition row = new RowDefinition();
                    row.Height = new GridLength(40, GridUnitType.Pixel);
                    grid.RowDefinitions.Add(row);
                }

                for (int i = 0; i < 36; i++)
                {
                    for (int j = 0; j < 36; j++)
                    {
                        Label t1 = new Label()
                        {
                            FontSize = 10,
                            FontFamily = new FontFamily("consolas"),
                            FontWeight = FontWeights.SemiBold,
                            BorderBrush = Brushes.LightGray,
                            BorderThickness = new Thickness(2),
                            HorizontalContentAlignment = HorizontalAlignment.Center,
                            VerticalContentAlignment = VerticalAlignment.Center,
                        };
                        Grid.SetRow(t1, i);
                        Grid.SetColumn(t1, j);
                        grid.Children.Add(t1); //Add the Label Control to the Grid created
                    }
                }

Based on the property names it looks like you are trying to convert a string to a date by assignment:

claimantAuxillaryRecord.TPOCDate2 = tpoc2[0].ToString();

It is probably due to the current UI culture and therefore it cannot interpret the date string correctly when assigned.

This will show you clues about why the linker doesn't want the installed library:

LD_DEBUG=all make ...

I had the same problem in a different context: my system /lib/libz.so.1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS.

Here is bash script that can do it for you. It's modified version of http://snippets.freerobby.com/post/491644841/remove-merged-branches-in-git script. My modification enables it to support different remote locations.

#!/bin/bash

current_branch=$(git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/')
if [ "$current_branch" != "master" ]; then
  echo "WARNING: You are on branch $current_branch, NOT master."
fi
echo -e "Fetching merged branches...\n"

git remote update --prune
remote_branches=$(git branch -r --merged | grep -v '/master$' | grep -v "/$current_branch$")
local_branches=$(git branch --merged | grep -v 'master$' | grep -v "$current_branch$")
if [ -z "$remote_branches" ] && [ -z "$local_branches" ]; then
  echo "No existing branches have been merged into $current_branch."
else
  echo "This will remove the following branches:"
  if [ -n "$remote_branches" ]; then
echo "$remote_branches"
  fi
  if [ -n "$local_branches" ]; then
echo "$local_branches"
  fi
  read -p "Continue? (y/n): " -n 1 choice
  echo
  if [ "$choice" == "y" ] || [ "$choice" == "Y" ]; then
    remotes=`echo "$remote_branches" | sed 's/\(.*\)\/\(.*\)/\1/g' | sort -u`
# Remove remote branches
for remote in $remotes
do
        branches=`echo "$remote_branches" | grep "$remote/" | sed 's/\(.*\)\/\(.*\)/:\2 /g' | tr -d '\n'`
        git push $remote $branches 
done

# Remove local branches
git branch -d `git branch --merged | grep -v 'master$' | grep -v "$current_branch$" | sed 's/origin\///g' | tr -d '\n'`
  else
echo "No branches removed."
  fi
fi

Happened to me as well. In my case, the bad ref was master, and I did the following:

rm .git/refs/remotes/origin/master
git fetch

This made git restore the ref file. After that everything worked as expected again.

The safest command to push different local Git branches to Heroku/master.

git push -f heroku branch_name:master

Note: Although, you can push without using the -f, the -f (force flag) is recommended in order to avoid conflicts with other developers’ pushes.

You have 3 options

1. Pull and push again:

   git pull; git push
   

2. Push into different branch:

   git push origin master:foo
   

   and merge it on remote (either by git or pull-request)

   git merge foo
   

3. Force it (not recommended unless you deliberately changed commits via rebase):

   git push origin master -f
   

   If still refused, disable denyCurrentBranch on remote repository:

   git config receive.denyCurrentBranch ignore
   

Be careful how you define the table for you will get different results on insert. Consider the following

CREATE TABLE IF NOT EXISTS t1 (id INTEGER PRIMARY KEY, a TEXT UNIQUE, b TEXT);
INSERT INTO t1 (a, b) VALUES
    ('Alice', 'Some title'),
    ('Bob', 'Palindromic guy'),
    ('Charles', 'chucky cheese'),
    ('Alice', 'Some other title') 
    ON CONFLICT(a) DO UPDATE SET b=excluded.b;
CREATE TABLE IF NOT EXISTS t2 (id INTEGER PRIMARY KEY, a TEXT UNIQUE, b TEXT, UNIQUE(a) ON CONFLICT REPLACE);
INSERT INTO t2 (a, b) VALUES
    ('Alice', 'Some title'),
    ('Bob', 'Palindromic guy'),
    ('Charles', 'chucky cheese'),
    ('Alice', 'Some other title');

$ sqlite3 test.sqlite

sqlite> 

While the insert/update effect is the same, the id changes based on the table definition type (see the second table where 'Alice' now has id = 4; the first table is doing more of what I expect it to do, keep the PRIMARY KEY the same). Be aware of this effect.

If you want your current uncommited changes on the current branch to move to a new branch, use the following command to create a new branch and copy the uncommitted changes automatically.

git checkout -b branch_name

This will create a new branch from your current branch (assuming it to be master), copy the uncommited changes and switch to the new branch.

Add files to stage & commit your changes to the new branch.

git add .
git commit -m "First commit"

Since, a new branch is created, before pushing it to remote, you need to set the upstream. Use the below command to set the upstream and push it to remote.

git push --set-upstream origin feature/feature/NEWBRANCH

Once you hit this command, a new branch will be created at the remote and your new local branch will be pushed to remote.

Now, if you want to throw away your uncommited changes from master branch, use:

git checkout master -f

This will throw away any uncommitted local changes on checkout.

just had the same issue, but i could not find the conflicting branch anymore.

in my case the repo had and "foo" branch before, but not anymore and i tried to create and checkout "foo/bar" from remote. As i said "foo" did not exist anymore, but the issue persisted.

In the end, the branch "foo" was still in the .git/config file, after deleting it everything was alright :)

This worked for me:

git init
git remote add origin PATH/TO/REPO
git fetch
git reset origin/master  # Required when the versioned files existed in path before "git init" of this repo.
git checkout -t origin/master

NOTE: -t will set the upstream branch for you, if that is what you want, and it usually is.

@Josh Lindsey already answered perfectly fine. But I want to add some information since I often use ssh.

Therefore just change:

git remote add origin [email protected]:/path/to/my_project.git

to:

git remote add origin ssh://[email protected]/path/to/my_project

Note that the colon between domain and path isn't there anymore.

Taking @chrissr's answer and running with it, this code can be implemented into a nice category on NSUserDefaults to save and retrieve custom objects:

@interface NSUserDefaults (NSUserDefaultsExtensions)

- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key;
- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key;

@end


@implementation NSUserDefaults (NSUserDefaultsExtensions)


- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key {
    NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    [self setObject:encodedObject forKey:key];
    [self synchronize];

}

- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key {
    NSData *encodedObject = [self objectForKey:key];
    id<NSCoding> object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
    return object;
}

@end

Usage:

[[NSUserDefaults standardUserDefaults] saveCustomObject:myObject key:@"myKey"];

Pardon my ignorance, but why are you using $('.salesperson') instead of $('#salesperson') when dealing with an ID?

Try using unbindService() in OnUserLeaveHint(). It prevents the the ServiceConnection leaked scenario and other exceptions.
I used it in my code and works fine.

It may seem as being too cautious, but I frequently zip a copy of whatever I've been working on before I make source control changes. In a Gitlab project I'm working on, I recently deleted a remote branch by mistake that I wanted to keep after merging a merge request. It turns out all I had to do to get it back with the commit history was push again. The merge request was still tracked by Gitlab, so it still shows the blue 'merged' label to the right of the branch. I still zipped my local folder in case something bad happened.

Play with Bash:

git show HEAD | sed -n 1p | cut -d " " -f 2

This works:

sudo chmod -R gituser.gituser objects

I encountered this issue by putting a XML file into the src/main/resources wrongly, I deleted it and then all back to normal.

FWIW, git rebase interactive now has a "reword" option, which makes this much less painful!

If you don't want execute assembly goal on package, you can use next command:

mvn package assembly:single

Here package is keyword.

Is this going to put people off coming to Scala?

Yes, but it will also prevent people from being put off. I've considered the lack of collections that use higher-kinded types to be a major weakness ever since Scala gained support for higher-kinded types. It make the API docs more complicated, but it really makes usage more natural.

Is this going to give scala a bad name in the commercial world as an academic plaything that only dedicated PhD students can understand? Are CTOs and heads of software going to get scared off?

Some probably will. I don't think Scala is accessible to many "professional" developers, partially due to the complexity of Scala and partly due to the unwillingness of many developers to learn. The CTOs who employ such developers will rightly be scared off.

Was the library re-design a sensible idea?

Absolutely. It makes collections fit much better with the rest of the language and the type system, even if it still has some rough edges.

If you're using scala commercially, are you worried about this? Are you planning to adopt 2.8 immediately or wait to see what happens?

I'm not using it commercially. I'll probably wait until at least a couple revs into the 2.8.x series before even trying to introduce it so that the bugs can be flushed out. I'll also wait to see how much success EPFL has in improving its development a release processes. What I'm seeing looks hopeful, but I work for a conservative company.

One the more general topic of "is Scala too complicated for mainstream developers?"...

Most developers, mainstream or otherwise, are maintaining or extending existing systems. This means that most of what they use is dictated by decisions made long ago. There are still plenty of people writing COBOL.

Tomorrow's mainstream developer will work maintaining and extending the applications that are being built today. Many of these applications are not being built by mainstream developers. Tomorrow's mainstream developers will use the language that is being used by today's most successful developers of new applications.

You can also force a push by adding the + symbol before your branch name.

git push origin +some_branch

int add(int a, int b)
{
  return (a+b);
}
int minus(int a, int b)
{
  return (a-b);
}

typedef int (*math_func)(int, int); //declaration of function pointer

int main()
{
  math_func addition = add;  //typedef assigns a new variable i.e. "addition" to original function "add"
  math_func substract = minus; //typedef assigns a new variable i.e. "substract" to original function "minus"

  int c = addition(11, 11);   //calling function via new variable
  printf("%d\n",c);
  c = substract(11, 5);   //calling function via new variable
  printf("%d",c);
  return 0;
}

Output of this is :

22

6

Note that, same math_func definer has been used for the declaring both the function.

Same approach of typedef may be used for extern struct.(using sturuct in other file.)

SSH based git access method can be specified in <repo_path>/.git/config using either a full URL or an SCP-like syntax, as specified in http://git-scm.com/docs/git-clone:

URL style:

url = ssh://[user@]host.xz[:port]/path/to/repo.git/

SCP style:

url = [user@]host.xz:path/to/repo.git/

Notice that the SCP style does not allow a direct port change, relying instead on an ssh_config host definition in your ~/.ssh/config such as:

Host my_git_host
HostName git.some.host.org
Port 24589
User not_a_root_user

Then you can test in a shell with:

ssh my_git_host

and alter your SCP-style URI in <repo_path>/.git/config as:

url = my_git_host:path/to/repo.git/

Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC 2010 session #209, which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related.

You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force.

Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups.

I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.

Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly (knowing the password, of course) without the need to even undersand its algorithm. It's not that easy anymore, unfortunately.

I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested.

In theory, Apple's algos should be designed in a way that makes the data still safe (i.e. practically unbreakable by brute force methods) to any attacker knowing the exact encryption method. And in WWDC session 209 they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions. After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help.

Good luck!

You can create a detached master branch using only porcelain Git commands:

git init
touch GO_AWAY
git add GO_AWAY
git commit -m "GO AWAY - this branch is detached from reality"

That gives us a master branch with a rude message (you may want to be more polite). Now we create our "real" branch (let's call it trunk in honour of SVN) and divorce it from master:

git checkout -b trunk
git rm GO_AWAY
git commit --amend --allow-empty -m "initial commit on detached trunk"

Hey, presto! gitk --all will show master and trunk with no link between them.

The "magic" here is that --amend causes git commit to create a new commit with the same parent as the current HEAD, then make HEAD point to it. But the current HEAD doesn't have a parent as it's the initial commit in the repository, so the new HEAD doesn't get one either, making them detached from each other.

The old HEAD commit doesn't get deleted by git-gc because refs/heads/master still points to it.

The --allow-empty flag is only needed because we're committing an empty tree. If there were some git add's after the git rm then it wouldn't be necessary.

In truth, you can create a detached branch at any time by branching the initial commit in the repository, deleting its tree, adding your detached tree, then doing git commit --amend.

I know this doesn't answer the question of how to modify the default branch on the remote repository, but it gives a clean answer on how to create a detached branch.

Try running also

sudo rm -rf /var/db/receipts/com.mysql.*

The whole git resetting business looked far to complicating for me.

So I did something along the lines to get my src folder in the state i had a few commits ago

# reset the local state
git reset <somecommit> --hard 
# copy the relevant part e.g. src (exclude is only needed if you specify .)
tar cvfz /tmp/current.tgz --exclude .git  src
# get the current state of git
git pull
# remove what you don't like anymore
rm -rf src
# restore from the tar file
tar xvfz /tmp/current.tgz
# commit everything back to git
git commit -a
# now you can properly push
git push

This way the state of affairs in the src is kept in a tar file and git is forced to accept this state without too much fiddling basically the src directory is replaced with the state it had several commits ago.

The previously mentioned solutions work well with chrome but not on Firefox.

I found a Solution that works well both in Chrome and Firefox(not on IE). Add the following attributes to the CSS for your SELECTelement and adjust the margin-top to suit your needs.

select {
    -webkit-appearance: none;
    -moz-appearance: none;
    text-indent: 1px;
    text-overflow: '';
}

Hope this helps :)

MonoDevelop, the IDE associated with Mono Project should be enough for C# development on Linux. Now I don't know any good profilers and other tools for C# development on Linux. But then again mind you, that C# is a language more native to windows. You are better developing C# apps for windows than for linux.

EDIT: When you download MonoDevelop from the Ubuntu Software Center, it will contain pretty much everything you need to get started right away (Compiler, Runtime Environment, IDE). If you would like more information, see the following links:

• http://en.wikipedia.org/wiki/MonoDevelop
• http://en.wikipedia.org/wiki/Mono_%28software%29

You can extends for any language with 1 keybinding with augroup command, for example:

augroup rungroup
    autocmd!
    autocmd BufRead,BufNewFile *.go nnoremap <F5> :exec '!go run' shellescape(@%, 1)<cr>
    autocmd BufRead,BufNewFile *.py nnoremap <F5> :exec '!python' shellescape(@%, 1)<cr>
augroup END

The easiest way is to just learn how to do DOM traversing and manipulation with the plain DOM api (you would probably call this: normal JavaScript).

This can however be a pain for some things. (which is why libraries were invented in the first place).

Googling for "javascript DOM traversing/manipulation" should present you with plenty of helpful (and some less helpful) resources.

The articles on this website are pretty good: http://www.htmlgoodies.com/primers/jsp/

And as Nosredna points out in the comments: be sure to test in all browsers, because now jQuery won't be handling the inconsistencies for you.

// Instead Of 
var index = arr.indexOf(200)

// Use 
var index = arr.includes(200);

Please Note: Includes function is a simple instance method on the array and helps to easily find if an item is in the array(including NaN unlike indexOf)

import re
expression = "Nov 05 20:10:09 2020"
reg_ex = r'((Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec) ([0-2][0-9]|(3)[0-1]) (([0-1][0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9])) (\d{4}))'
assert re.fullmatch(reg_ex, expression), True

Expaination with respect to given Example

• Nov = A group of possible months i.e. (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)
• 05 = A group of valid days i.e. ([0-2][0-9]|(3)[0-1])
• 20:10:09 = A group for getting valid Hours : ([0-1][0-9]|2[0-3]), Minutes : ([0-5][0-9]) and Seconds : ([0-5][0-9])
• 2020 = A group for getting year i.e (\d{4}))

Bootstrap / CSS

Use col-12, btn-block, w-100, form-control or width:100%

Most trees are formed by the data you are processing.

Say you have a person class that includes details of someone’s parents, would you rather have the tree structure as part of your “domain class”, or use a separate tree class that contained links to your person objects? Think about a simple operation like getting all the grandchildren of a person, should this code be in the person class, or should the user of the person class have to know about a separate tree class?

Another example is a parse tree in a compiler…

What both of these examples show is that the concept of a tree is part of the domain of the data and using a separate general purpose tree at least doubles the number of objects that are created as well as making the API harder to program again.

What we want is a way to reuse the standard tree operations, without having to re-implement them for all trees, while at the same time, not having to use a standard tree class. Boost has tried to solve this type of problem for C++, but I yet to see any effect for .NET get adapted.

The JavaDoc explains it very well:

With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.

SO_TIMEOUT is the timeout that a read() call will block. If the timeout is reached, a java.net.SocketTimeoutException will be thrown. If you want to block forever put this option to zero (the default value), then the read() call will block until at least 1 byte could be read.

I'm not familiar with SSRS, but you can get the beginning and end of the previous month in VB.Net using the DateTime constructor, like this:

Dim prevMonth As DateTime = yourDate.AddMonths(-1)

Dim prevMonthStart As New DateTime(prevMonth.Year, prevMonth.Month, 1)
Dim prevMonthEnd As New DateTime(prevMonth.Year, prevMonth.Month, DateTime.DaysInMonth(prevMonth.Year, prevMonth.Month))

(yourDate can be any DateTime object, such as DateTime.Today or #12/23/2003#)

Someone should mark Johannes Weiß's comment as the answer to this question. That is exactly why xml documents can't just be loaded in a DOM Document class.

print('Office {} {}'.format(office_version, click_and_run))

Remarks

• Didn't test with office < 2010 though
• Python typing is different between the registry functions and the office functions since I wrote the registry ones before finding out that pypy / python2 does not like typing... On those python interpreters you might just remove typing completly
• Any improvements are highly welcome

Just stumbled on the answer. android:inputType="textPassword" does work with android:hint, same as android:password. The only difference is when I use android:gravity="center", the hint will not show if I'm using android:inputType. Case closed!

Seems like the issue is caused when there is version conflict between packages.config and app.config. In app.config you have assembly binding redirects automatically generated by thing called "AutoGenerateBindingRedirects". When enabled each time you download nuget package it will, additionaly to making new entry in packages.config, add this binding redirect information to app.config, what's the purpose of this is explained here: Assembly Binding redirect: How and Why?

There you can read what user @Evk wrote:

Why are binding redirects needed at all? Suppose you have application A that references library B, and also library C of version 1.1.2.5. Library B in turn also references library C, but of version 1.1.1.0. Now we have a conflict, because you cannot load different versions of the same assembly at runtime. To resolve this conflict you might use binding redirect, usually to the new version

So, QUICK FIX: Remove all entries in app.config.

In my case just by doing that program started working, but it will probably work only if you don't have any version conflicts of the same assembly at runtime.

If you do have such conflict you should fix these version numbers in app.config to match actually used versions of assemblies, but manual process is painful, so I suggest to auto-generate them again by opening Package Manager Console and perform packages reinstallation by typing Update-Package -reinstall

Assuming all of these columns are int, then the first thing to sort out is converting one or more of them to a better data type - int division performs truncation, so anything less than 100% would give you a result of 0:

select (100.0 * (SPGI09_EARLY_OVER_T – SPGI09_OVER_WK_EARLY_ADJUST_T)) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)
from 
CSPGI09_OVERSHIPMENT 

Here, I've mutiplied one of the numbers by 100.0 which will force the result of the calculation to be done with floats rather than ints. By choosing 100, I'm also getting it ready to be treated as a %.

I was also a little confused by your bracketing - I think I've got it correct - but you had brackets around single values, and then in other places you had a mix of operators (- and /) at the same level, and so were relying on the precedence rules to define which operator applied first.

If you want to change your 'sa' password with SQL Server Management Studio, here are the steps:

1. Login using Windows Authentication and ".\SQLExpress" as Server Name

2. Change server authentication mode - Right click on root, choose Properties, from Security tab select "SQL Server and Windows Authentication mode", click OK

3. Set sa password - Navigate to Security > Logins > sa, right click on it, choose Properties, from General tab set the Password (don't close the window)

4. Grant permission - Go to Status tab, make sure the Grant and Enabled radiobuttons are chosen, click OK

5. Restart SQLEXPRESS service from your local services (Window+R > services.msc)

The year() function just retrieves the year component of the underlying Date object, so it returns a number.

Calling format('YYYY') will invoke moment's string formatting functions, which will parse the format string supplied, and build a new string containing the appropriate data. Since you only are passing YYYY, then the result will be a string containing the year.

If all you need is the year, then use the year() function. It will be faster, as there is less work to do.

Do note that while years are the same in this regard, months are not! Calling format('M') will return months in the range 1-12. Calling month() will return months in the range 0-11. This is due to the same behavior of the underlying Date object.

A little background

Traceview is a graphical viewer for execution logs that you create by using the Debug class to log tracing information in your code. Traceview can help you debug your application and profile its performance. Enabling it creates a .trace file in the sdcard root folder which can then be extracted by ADB and processed by traceview bat file for processing. It also can get added by the DDMS.

It is a system used internally by the logger. In general unless you are using traceview to extract the trace file this error shouldnt bother you. You should look at error/logs directly related to your application

How do I enable it:

There are two ways to generate trace logs:

1. Include the Debug class in your code and call its methods such as startMethodTracing() and stopMethodTracing(), to start and stop logging of trace information to disk. This option is very precise because you can specify exactly where to start and stop logging trace data in your code.

2. Use the method profiling feature of DDMS to generate trace logs. This option is less precise because you do not modify code, but rather specify when to start and stop logging with DDMS. Although you have less control on exactly where logging starts and stops, this option is useful if you don't have access to the application's code, or if you do not need precise log timing.

But the following restrictions exist for the above

If you are using the Debug class, your application must have permission to write to external storage (WRITE_EXTERNAL_STORAGE).

If you are using DDMS: Android 2.1 and earlier devices must have an SD card present and your application must have permission to write to the SD card. Android 2.2 and later devices do not need an SD card. The trace log files are streamed directly to your development machine.

So in essence the traceFile access requires two things

1.) Permission to write a trace log file i.e. WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE for good measure

2.) An emulator with an SDCard attached with sufficient space. The doc doesnt say if this is only for DDMS but also for debug, so I am assuming this is also true for debugging via the application.

What do I do with this error:

Now the error is essentially a fall out of either not having the sdcard path to create a tracefile or not having permission to access it. This is an old thread, but the dev behind the bounty, check if are meeting the two prerequisites. You can then go search for the .trace file in the sdcard folder in your emulator. If it exists it shouldn't be giving you this problem, if it doesnt try creating it by adding the startMethodTracing to your app.
I'm not sure why it automatically looks for this file when the logger kicks in. I think when an error/log event occurs , the logger internally tries to write to trace file and does not find it, in which case it throws the error.Having scoured through the docs, I don't find too many references to why this is automatically on. But in general this doesn't affect you directly, you should check direct application logs/errors. Also as an aside Android 2.2 and later devices do not need an SD card for DDMS trace logging. The trace log files are streamed directly to your development machine.

Additional information on Traceview:

Copying Trace Files to a Host Machine

After your application has run and the system has created your trace files .trace on a device or emulator, you must copy those files to your development computer. You can use adb pull to copy the files. Here's an example that shows how to copy an example file, calc.trace, from the default location on the emulator to the /tmp directory on the emulator host machine:

adb pull /sdcard/calc.trace /tmp Viewing Trace Files in Traceview To run Traceview and view the trace files, enter traceview . For example, to run Traceview on the example files copied in the previous section, use:

traceview /tmp/calc Note: If you are trying to view the trace logs of an application that is built with ProGuard enabled (release mode build), some method and member names might be obfuscated. You can use the Proguard mapping.txt file to figure out the original unobfuscated names. For more information on this file, see the Proguard documentation.

I think any other answer regarding positioning of oncreate statements or removing uses-sdk are not related, but this is Android and I could be wrong. Would be useful to redirect this question to an android engineer or post it as a bug

I just hit a problem with this. Mine was a fall off from changing the input to a button and I'd had a badly written /> tag terminator:

So I had:

<button name="submit_login" type="submit" class="login" />Login</button>

You need to setup both GOPATH and GOBIN. Make sure you have done the following (please replace ~/go with your preferred GOPATH and subsequently change GOBIN). This is tested on Ubuntu 16.04 LTS.

export GOPATH=~/go 

mkdir ~/go/bin

export GOBIN=$GOPATH/bin

The selected answer did not solve the problem for me.

You actually don't need the screen resolution, what you want is the browser's dimensions because in many cases the the browser is windowed, and even in maximized size the browser won't take 100% of the screen.

what you want is View-port-height and View-port-width:

<div style="height: 50vh;width: 25vw"></div>

this will render a div with 50% of the inner browser's height and 25% of its width.

(to be honest this answer was part of what @Hendrik_Eichler wanted to say, but he only gave a link and didn't address the issue directly)

Beyond what's been said already about selectors, you may want to look at the NSInvocation class.

An NSInvocation is an Objective-C message rendered static, that is, it is an action turned into an object. NSInvocation objects are used to store and forward messages between objects and between applications, primarily by NSTimer objects and the distributed objects system.

An NSInvocation object contains all the elements of an Objective-C message: a target, a selector, arguments, and the return value. Each of these elements can be set directly, and the return value is set automatically when the NSInvocation object is dispatched.

Keep in mind that while it's useful in certain situations, you don't use NSInvocation in a normal day of coding. If you're just trying to get two objects to talk to each other, consider defining an informal or formal delegate protocol, or passing a selector and target object as has already been mentioned.

Jérôme Petazzoni has a pretty interesting blog post on how to Attach a volume to a container while it is running. This isn't something that's built into Docker out of the box, but possible to accomplish.

As he also points out

This will not work on filesystems which are not based on block devices.

It will only work if /proc/mounts correctly lists the block device node (which, as we saw above, is not necessarily true).

Also, I only tested this on my local environment; I didn’t even try on a cloud instance or anything like that

YMMV

Unlike centralized version control systems, Git clones the entire repository, so you don't only get the current remote files, but the whole history. You local repository will include all this.

There might have been tags to mark a particular version at the time. If not, you can create them yourself locally. A good way to do this is to use git log or perhaps more visually with tools like gitk (perhaps gitk --all to see all the branches and tags). If you can spot the commits hashes that were used at the time, you can tag them using git tag <hash> and then check those out in new working copies (for example git checkout -b new_branch_name tag_name or directly with the hash instead of the tag name).

Javascripts .call() and .apply() methods allow you to set the context for a function.

var myfunc = function(){
    alert(this.name);
};

var obj_a = {
    name:  "FOO"
};

var obj_b = {
    name:  "BAR!!"
};

Now you can call:

myfunc.call(obj_a);

Which would alert FOO. The other way around, passing obj_b would alert BAR!!. The difference between .call() and .apply() is that .call() takes a comma separated list if you're passing arguments to your function and .apply() needs an array.

myfunc.call(obj_a, 1, 2, 3);
myfunc.apply(obj_a, [1, 2, 3]);

Therefore, you can easily write a function hook by using the apply() method. For instance, we want to add a feature to jQuerys .css() method. We can store the original function reference, overwrite the function with custom code and call the stored function.

var _css = $.fn.css;
$.fn.css = function(){
   alert('hooked!');
   _css.apply(this, arguments);
};

Since the magic arguments object is an array like object, we can just pass it to apply(). That way we guarantee, that all parameters are passed through to the original function.

Yes Fiddler is an option for me:

1. Open Fiddler menu > Rules > Customize Rules (this effectively edits CustomRules.js).
2. Find the function OnBeforeResponse

3. Add the following lines:

   oSession.oResponse.headers.Remove("X-Frame-Options");
   oSession.oResponse.headers.Add("Access-Control-Allow-Origin", "*");
   

4. Remember to save the script!

Thanks @all!

don't use: query("SET NAMES utf8"); this is setup stuff and not a query. put it right afte a connection start with setCharset() (or similar method)

some little thing in parctice:

status:

• mysql server by default talks latin1
• your hole app is in utf8
• connection is made without any extra (so: latin1) (no SET NAMES utf8 ..., no set_charset() method/function)

Store and read data is no problem as long mysql can handle the characters. if you look in the db you will already see there is crap in it (e.g.using phpmyadmin).

until now this is not a problem! (wrong but works often (in europe)) ..

..unless another client/programm or a changed library, which works correct, will read/save data. then you are in big trouble!

Just quote the argument to echo:

( IFS=$'\n'; echo "${my_array[*]}" )

the sub shell helps restoring the IFS after use

ICMP Block rule example:

# Drop ICMP (PING)
$iptables -t mangle -A PREROUTING -p icmp -j NFLOG --nflog-prefix 'ICMP Block'

And you can search prefix "ICMP Block" in log:

/var/log/ulog/syslogemu.log

For "English locale" file names, this works nicely. I'm using this for sanitizing uploaded file names. The file name is not meant to be linked to anything on disk, it's for when the file is being downloaded hence there are no path checks.

$file_name = preg_replace('/([^\x20-~]+)|([\\/:?"<>|]+)/g', '_', $client_specified_file_name);

Basically it strips all non-printable and reserved characters for Windows and other OSs. You can easily extend the pattern to support other locales and functionalities.

You can set time limit:

ini_set('max_execution_time', 1000000000000000);

you can do it simply as below:

 public static int[] getRGB(final String rgb)
{
    final int[] ret = new int[3];
    for (int i = 0; i < 3; i++)
    {
        ret[i] = Integer.parseInt(rgb.substring(i * 2, i * 2 + 2), 16);
    }
    return ret;
}

For Example

getRGB("444444") = 68,68,68   
getRGB("FFFFFF") = 255,255,255

It's getElementById()

Note the lower-case d in Id.

Here is what I did recently in PHP on one of my bigger systems:

1. User inputs newsletter text and selects the recipients (which generates a query to retrieve the email addresses for later).

2. Add the newsletter text and recipients query to a row in mysql table called *email_queue*

   • (The table email_queue has the columns "to" "subject" "body" "priority")

3. I created another script, which runs every minute as a cron job. It uses the SwiftMailer class. This script simply:

   • during business hours, sends all email with priority == 0

   • after hours, send other emails by priority

Depending on the hosts settings, I can now have it throttle using standard swiftmailers plugins like antiflood and throttle...

$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));

and

$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin( 100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE ));

etc, etc..

I have expanded it way beyond this pseudocode, with attachments, and many other configurable settings, but it works very well as long as your server is setup correctly to send email. (Probably wont work on shared hosting, but in theory it should...) Swiftmailer even has a setting

$message->setReturnPath

Which I now use to track bounces...

Happy Trails! (Happy Emails?)

If you want to keep the path to the file and just remove the extension

>>> file = '/root/dir/sub.exten/file.data.1.2.dat'
>>> print ('.').join(file.split('.')[:-1])
/root/dir/sub.exten/file.data.1.2

You can use Reflections framework for this

import static org.reflections.ReflectionUtils.*;
Set<Method> getters = ReflectionUtils.getAllMethods(someClass,
      withModifier(Modifier.PUBLIC), withPrefix("get"), withAnnotation(annotation));

Python3's range is Python2's xrange. There's no need to wrap an iter around it. To get an actual list in Python3, you need to use list(range(...))

If you want something that works with Python2 and Python3, try this

try:
    xrange
except NameError:
    xrange = range

Although this topic has already been answered there's more to say.

First of all: Clearly we need some definitions here. The InetAddress.getLocalHost().getHostName() gives you the name of the host as seen from a network perspective. The problems with this approach are well documented in the other answers: it often requires a DNS lookup, it's ambiguous if the host has multiple network interfaces and it just plain fails sometimes (see below).

But on any OS there's another name as well. A name of the host that gets defined very early in the boot process, long before the network is initialized. Windows refers to this as computername, Linux calls it kernel hostname and Solaris uses the word nodename. I like best the word computername, so I'll use that word from now on.

Finding the computername

• On Linux/Unix the computername is what you get from the C function gethostname(), or hostname command from shell or HOSTNAME environment variable in Bash-like shells.

• On Windows the computername is what you get from environment variable COMPUTERNAME or Win32 GetComputerName function.

Java has no way of obtaining what I've defined as 'computername'. Sure, there are workarounds as described in other answers, like for Windows calling System.getenv("COMPUTERNAME"), but on Unix/Linux there's no good workaround without resorting to JNI/JNA or Runtime.exec(). If you don't mind a JNI/JNA solution then there's gethostname4j which is dead simple and very easy to use.

Let's move on with two examples, one from Linux and one from Solaris, which demonstrate how you can easily get into a situation where you cannot obtain the computername using standard Java methods.

Linux example

On a newly created system, where the host during installation has been named as 'chicago', we now change the so-called kernel hostname:

$ hostnamectl --static set-hostname dallas

Now the kernel hostname is 'dallas', as evident from the hostname command:

$ hostname
dallas

But we still have

$ cat /etc/hosts
127.0.0.1   localhost
127.0.0.1   chicago

There's no misconfiguration in this. It just means the host's networked name (or rather the name of the loopback interface) is different from the host's computername.

Now, try executing InetAddress.getLocalHost().getHostName() and it will throw java.net.UnknownHostException. You are basically stuck. There's no way to retrieve neither the value 'dallas' nor the value 'chicago'.

Solaris example

The example below is based on Solaris 11.3.

The host has deliberately been configured so that the loopback name <> nodename.

In other words we have:

$ svccfg -s system/identity:node listprop config
...
...
config/loopback             astring        chicago
config/nodename             astring        dallas

and the contents of /etc/hosts :

:1 chicago localhost
127.0.0.1 chicago localhost loghost

and the result of the hostname command would be:

$ hostname
dallas

Just like in the Linux example a call to InetAddress.getLocalHost().getHostName() will fail with

java.net.UnknownHostException: dallas:  dallas: node name or service name not known

Just like the Linux example you are now stuck. There's no way to retrieve neither the value 'dallas' nor the value 'chicago'.

When will you really struggle with this?

Very often you'll find that InetAddress.getLocalHost().getHostName() will indeed return a value which is equal to the computername. So there's no problem (except for the added overhead of name resolution).

The problem arises typically within PaaS environments where there's a difference between computername and the name of the loopback interface. For example people report problems in Amazon EC2.

Bug/RFE reports

A bit of searching reveals this RFE report : link1, link2. However, judging from the comments on that report the issue seems to have been largely misunderstood by the JDK team, so it is unlikely it will be addressed.

I like the comparison in the RFE to other programming languages.

This can't be done in chrome now to avoid spamming, refer to javascript onbeforeunload not showing custom message for more details.

In reading through Beazley & Jones PCB, I have stumbled on an explicit and practical use-case for __getattr__ that helps answer the "when" part of the OP's question. From the book:

"The __getattr__() method is kind of like a catch-all for attribute lookup. It's a method that gets called if code tries to access an attribute that doesn't exist." We know this from the above answers, but in PCB recipe 8.15, this functionality is used to implement the delegation design pattern. If Object A has an attribute Object B that implements many methods that Object A wants to delegate to, rather than redefining all of Object B's methods in Object A just to call Object B's methods, define a __getattr__() method as follows:

def __getattr__(self, name):
    return getattr(self._b, name)

where _b is the name of Object A's attribute that is an Object B. When a method defined on Object B is called on Object A, the __getattr__ method will be invoked at the end of the lookup chain. This would make code cleaner as well, since you do not have a list of methods defined just for delegating to another object.

The DataTable.Clone() method works great when you want to create a completely new DataTable, but there might be cases where you would want to add the schema columns from one DataTable to another existing DataTable.

For example, if you've derived a new subclass from DataTable, and want to import schema information into it, you couldn't use Clone().

E.g.:

public class CoolNewTable : DataTable {
   public void FillFromReader(DbDataReader reader) {
       // We want to get the schema information (i.e. columns) from the 
       // DbDataReader and 
       // import it into *this* DataTable, NOT a new one.
       DataTable schema = reader.GetSchemaTable(); 
       //GetSchemaTable() returns a DataTable with the columns we want.

       ImportSchema(this, schema); // <--- how do we do this?
   }
}

The answer is just to create new DataColumns in the existing DataTable using the schema table's columns as templates.

I.e. the code for ImportSchema would be something like this:

void ImportSchema(DataTable dest, DataTable source) {
    foreach(var c in source.Columns)
        dest.Columns.Add(c);
}

or, if you're using Linq:

void ImportSchema(DataTable dest, DataTable source) {
    var cols = source.Columns.Cast<DataColumn>().ToArray();
    dest.Columns.AddRange(cols);
}

This was just one example of a situation where you might want to copy schema/columns from one DataTable into another one without using Clone() to create a completely new DataTable. I'm sure I've come across several others as well.

Stream is just an abstraction (or a wrapper) over a physical stream of bytes. This physical stream is called the base stream. So there is always a base stream over which a stream wrapper is created and thus the wrapper is named after the base stream type ie FileStream, MemoryStream etc.

The advantage of the stream wrapper is that you get a unified api to interact with streams of any underlying type usb, file etc.

Why would you treat data as stream - because data chunks are loaded on-demand, we can inspect/process the data as chunks rather than loading the entire data into memory. This is how most of the programs deal with big files, for eg encrypting an OS image file.

Your check should be:

if (Attachment != null  && Attachment.Length > 0)

First check if the Attachment is null and then lenght, since you are using && that will cause short-circut evaluation

&& Operator (C# Reference)

The conditional-AND operator (&&) performs a logical-AND of its bool operands, but only evaluates its second operand if necessary.

Previously you had the condition like: (Attachment.Length > 0 && Attachment != null), since the first condition is accessing the property Length and if Attachment is null, you end up with the exception, With the modified condition (Attachment != null && Attachment.Length > 0), it will check for null first and only moves further if Attachment is not null.

ACCESSING LOCAL WEBSITE WITH IIS without Physical Path Authentication

1. Make sure you have installed URL Rewrite to your IIS Manager

2. Open the URL Rewrite application then navigate to Inbound Rules>Import Rules

3. To import the rule, click the browse button then locate your .htaccess file then click import button

4. The text labeled with red are errors that are not accepted by IIS, so you have to remove them by clicking the errors in the converted rules and remove the text from the rewrite rules. Once you have get rid of the errors Click the APPLY button located at the top right corner. Then try to access your site without engaging users into the pool auth.

I hope it helps. That's what I did.

As the other answers already stated, Java does not provide this feature.

Implementation of this feature has been requested multiple times, e.g. as JDK-4194542: class name aliasing or JDK-4214789: Extend import to allow renaming of imported type.

From the comments:

This is not an unreasonable request, though hardly essential. The occasional use of fully qualified names is not an undue burden (unless the library really reuses the same simple names right and left, which is bad style).

In any event, it doesn't pass the bar of price/performance for a language change.

So I guess we will not see this feature in Java anytime soon :-P

One of the JPA ways for getting only particular columns is to ask for a Tuple object.

In your case you would need to write something like this:

CriteriaQuery<Tuple> cq = builder.createTupleQuery();
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<Tuple> tupleResult = em.createQuery(cq).getResultList();
for (Tuple t : tupleResult) {
    Long id = (Long) t.get(0);
    Long version = (Long) t.get(1);
}

Another approach is possible if you have a class representing the result, like T in your case. T doesn't need to be an Entity class. If T has a constructor like:

public T(Long id, Long version)

then you can use T directly in your CriteriaQuery constructor:

CriteriaQuery<T> cq = builder.createQuery(T.class);
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<T> result = em.createQuery(cq).getResultList();

See this link for further reference.

As far as I know, Javascript has dynamic arrays. You can add,delete and modify the elements on the fly.

var myArray = [1,2,3,4,5,6,7,8,9,10];
myArray.push(11);
document.writeln(myArray);  // Gives 1,2,3,4,5,6,7,8,9,10,11


var myArray = [1,2,3,4,5,6,7,8,9,10];
var popped = myArray.pop();
document.writeln(myArray);  // Gives 1,2,3,4,5,6,7,8,9

You can even add elements like

var myArray = new Array()
myArray[0] = 10
myArray[1] = 20
myArray[2] = 30

you can even change the values

myArray[2] = 40

Printing Order

If you want in the same order, this would suffice. Javascript prints the values in the order of key values. If you have inserted values in the array in monotonically increasing key values, then they will be printed in the same way unless you want to change the order.

Page Submission

If you are using JavaScript you don't even need to submit the values to the different page. You can even show the data on the same page by manipulating the DOM.

I have tried all the solutions above, but the following solved my problem

chcon -R -t httpd_sys_rw_content_t your_file_directory

I developed an esoteric programming language just for this case. The best part about it is that it is schema less and platform independent. You just have to write a selector program, for your schedule, syntax of which is constrained by the set of rules described here -

https://github.com/tusharmath/sheql/wiki/Rules

The rules are extendible and you can add any sort of customization based on the kind of repetition logic you want to perform, without worrying about schema migrations etc.

This is a completely different approach and might have some disadvantages of its own.

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null.

Given your statement:

img1.ImageUrl = ConfigurationManager
                    .AppSettings
                    .Get("Url")
                    .Replace("###", randomString) 
                + Server.UrlEncode(
                      ((System.Web.UI.MobileControls.Form)Page
                      .FindControl("mobileForm"))
                      .Title);

I'm guessing either the call to AppSettings.Get("Url") is returning null because the value isn't found or the call to Page.FindControl("mobileForm") is returning null because the control isn't found.

You could easily break this out into multiple statements to solve the problem:

var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
                            as System.Web.UI.MobileControls.Form;

if(configUrl != null && mobileFormControl != null)
{
    img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}

Also try.

EXEC sp_fkeys 'tableName', 'schemaName'

with sp_fkeys you may filter the result by not only pk table name and schema but also with fk table name and schema. link

If you are on MacOS X and having problems with Imagemagick's convert, you might try reinstalling it with RSVG lib. Using HomeBrew:

brew remove imagemagick
brew install imagemagick --with-librsvg

Verify that it's delegating correctly:

$ convert -version
Version: ImageMagick 6.8.9-8 Q16 x86_64 2014-12-17 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2014 ImageMagick Studio LLC
Features: DPC Modules
Delegates: bzlib cairo fontconfig freetype jng jpeg lcms ltdl lzma png rsvg tiff xml zlib

It should display rsvg.

Push down the whole button. I suggest this it is looking nice in button.

#button:active {
    position: relative;
    top: 1px;
}

if you only want to push text increase top-padding and decrease bottom padding. You can also use line-height.

You could define the function that you would like to reuse as below:

var foo = function() {...}

And later you can set however many event listeners you want on your object to trigger that function using on('event') leaving a space in between as shown below:

$('#selector').on('keyup keypress blur change paste cut', foo);

If you have access to ES2015 functions, and you're looking for a more functional approach I'd go with something like:

const people = [
  { id: 1, name: 'serdar' },
  { id: 5, name: 'alex' },
  { id: 300, name: 'brittany' }
];

const idToRemove = 5;

const filteredPeople = people.filter((item) => item.id !== idToRemove);

// [
//   { id: 1, name: 'serdar' },
//   { id: 300, name: 'brittany' }
// [

Watch out though, filter() is non-mutating, so you'll get a new array back.

See the Mozilla Developer Network notes on Filter.

I'll suggest to create helper function and reuse it every time, you'll need it. Lets make function more general to be able to get not only last item, but also second from the last and so on.

function last(arr, i) {
    var i = i || 0;
    return arr[arr.length - (1 + i)];
}

Usage is simple

var arr = [1,2,3,4,5];
last(arr);    //5
last(arr, 1); //4
last(arr, 9); //undefined

Now, lets solve the original issue

Grab second to last item form array. If the last item in the loc_array is "index.html" grab the third to last item instead.

Next line does the job

last(loc_array, last(loc_array) === 'index.html' ? 2 : 1);

So, you'll need to rewrite

var newT = document.createTextNode(unescape(capWords(loc_array[loc_array.length-2]))); 

in this way

var newT = document.createTextNode(unescape(capWords(last(loc_array, last(loc_array) === 'index.html' ? 2 : 1)))); 

or use additional variable to increase readability

var nodeName = last(loc_array, last(loc_array) === 'index.html' ? 2 : 1);
var newT = document.createTextNode(unescape(capWords(nodeName)));

If you still have the serial console open, it will reserve the serial port. Close it, and try again.

This was a real issue for me, and quite a sneaky problem to try and remedy...

The problem I had was that a module that was installed on my WiFi adapter was conflicting with the Microsoft Virtual Adapter (or whatever it's actually called).

To fix it:

1. Hold the Windows Key + Push R
2. Type: ncpa.cpl in to the box, and hit OK.
3. Identify the network adapter you want to use for the hostednetwork, right-click it, and select Properties.
4. You'll see a big box in the middle of the properties window, under the heading The connection uses the following items:. Look down the list for anything that seems out of the ordinary, and uncheck it. Hit OK.
5. Try running the netsh wlan start hostednetwork command again.
6. Repeat steps 4 and 5 as necessary.

In my case my adapter was running a module called SoftEther Lightweight Network Protocol, which I believe is used to help connect to VPN Gate VPN servers via the SoftEther software.

If literally nothing else works, then I'd suspect something similar to the problem I encountered, namely that a module on your network adapter is interfering with the hostednetwork aspect of your driver.

The view controller must be a child of some UINavigationController for the .title property to take effect. If the UINavigationBar is simply a view, you need to push a navigation item containing the title, or modify the last navigation item:

UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
...
[bar pushNavigationItem:item animated:YES];
[item release];

or

bar.topItem.title = @"title text";

In .Net 5.x, update your ConfigureServices method in startup.cs with the below code

public void ConfigureServices(IServiceCollection services)
{
    ----------------
    ----------------
    services.AddMvc().AddJsonOptions(options =>
    {
        options.JsonSerializerOptions.ReferenceHandler = ReferenceHandler.Preserve;
    });
    ------------------
}

By default, serialization (System.Text.Json.Serialization) does not support objects with cycles and does not preserve duplicate references. Use Preserve to enable unique object reference preservation on serialization and metadata consumption to read preserved references on deserialization. MSDN Link

jQuery Templates is an example of something that uses this method to store HTML that will not be rendered directly (that’s the whole point) inside other HTML: http://api.jquery.com/jQuery.template/

Add on to ffpf

Screen.FromControl(this).Bounds

From Activity#showDialog(int):

This method is deprecated.
Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.

I ended up with this because other answers either lose resolution or work with UIImageView, not UIImage, or contain unnecessary actions:

Swift 3

extension UIImage {
    
    public func mask(with color: UIColor) -> UIImage {
        
        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        let context = UIGraphicsGetCurrentContext()!
        
        let rect = CGRect(origin: CGPoint.zero, size: size)
        
        color.setFill()
        self.draw(in: rect)
        
        context.setBlendMode(.sourceIn)
        context.fill(rect)
        
        let resultImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return resultImage
    }
    
}

If you define operator<< as a member function it will have a different decomposed syntax than if you used a non-member operator<<. A non-member operator<< is a binary operator, where a member operator<< is a unary operator.

// Declarations
struct MyObj;
std::ostream& operator<<(std::ostream& os, const MyObj& myObj);

struct MyObj
{
    // This is a member unary-operator, hence one argument
    MyObj& operator<<(std::ostream& os) { os << *this; return *this; }

    int value = 8;
};

// This is a non-member binary-operator, 2 arguments
std::ostream& operator<<(std::ostream& os, const MyObj& myObj)
{
    return os << myObj.value;
}

So.... how do you really call them? Operators are odd in some ways, I'll challenge you to write the operator<<(...) syntax in your head to make things make sense.

MyObj mo;

// Calling the unary operator
mo << std::cout;

// which decomposes to...
mo.operator<<(std::cout);

Or you could attempt to call the non-member binary operator:

MyObj mo;

// Calling the binary operator
std::cout << mo;

// which decomposes to...
operator<<(std::cout, mo);

You have no obligation to make these operators behave intuitively when you make them into member functions, you could define operator<<(int) to left shift some member variable if you wanted to, understand that people may be a bit caught off guard, no matter how many comments you may write.

Almost lastly, there may be times where both decompositions for an operator call are valid, you may get into trouble here and we'll defer that conversation.

Lastly, note how odd it might be to write a unary member operator that is supposed to look like a binary operator (as you can make member operators virtual..... also attempting to not devolve and run down this path....)

struct MyObj
{
    // Note that we now return the ostream
    std::ostream& operator<<(std::ostream& os) { os << *this; return os; }

    int value = 8;
};

This syntax will irritate many coders now....

MyObj mo;

mo << std::cout << "Words words words";

// this decomposes to...
mo.operator<<(std::cout) << "Words words words";

// ... or even further ...
operator<<(mo.operator<<(std::cout), "Words words words");

Note how the cout is the second argument in the chain here.... odd right?

QUICK FIX (not the best)

Change the import react-native header lines:

 #import <React/RCTBridgeModule.h>
 #import <React/RCTLog.h>

To:

 #import "RCTBridgeModule.h"
 #import "RCTLog.h"

Here is an example of changes I had to make for the library I was trying to use: Closes #46 - 'RCTBridgeModule.h' file not found.

I needed to do a little bit of testing myself of a button component. These tests work for me ;-)

import { shallow } from "enzyme";
import * as React from "react";
import Button from "../button.component";

describe("Button Component Tests", () => {
    it("Renders correctly in DOM", () => {
        shallow(
            <Button text="Test" />
        );
    });
    it("Expects to find button HTML element in the DOM", () => {
        const wrapper = shallow(<Button text="test"/>)
        expect(wrapper.find('button')).toHaveLength(1);
    });

    it("Expects to find button HTML element with className test in the DOM", () => {
        const wrapper = shallow(<Button className="test" text="test"/>)
        expect(wrapper.find('button.test')).toHaveLength(1);
    });

    it("Expects to run onClick function when button is pressed in the DOM", () => {
        const mockCallBackClick = jest.fn();
        const wrapper = shallow(<Button onClick={mockCallBackClick} className="test" text="test"/>);
        wrapper.find('button').simulate('click');
        expect(mockCallBackClick.mock.calls.length).toEqual(1);
    });
});

This is more or less a summary of three answers (by Sara Inés Calderón, klaxon and Gothburz), but as they all added something important, I consider it worth joining the solutions and adding some more explanation.

Considering your example, you can do calculations in your template using:

{{ 100 * (count/total) }}

However, this may result in a whole lot of decimal places, so using filters is a good way to go:

{{ 100 * (count/total) | number }}

By default, the number filter will leave up to three fractional digits, this is where the fractionSize argument comes in quite handy ({{ 100 * (count/total) | number:fractionSize }}), which in your case would be:

{{ 100 * (count/total) | number:0 }}

This will also round the result already:

angular.module('numberFilterExample', [])_x000D_
  .controller('ExampleController', ['$scope',_x000D_
    function($scope) {_x000D_
      $scope.val = 1234.56789;_x000D_
    }_x000D_
  ]);

        </td>_x000D_
      </tr>_x000D_
      <tr>_x000D_
        <td>3 Decimal places:</td>_x000D_
        <td>_x000D_

      </tr>_x000D_
      <tr>_x000D_
        <td>No fractions: </td>_x000D_
        <td><span>{{ val | number:0 }}</span> (rounded)</td>_x000D_
      </tr>_x000D_
    </table>_x000D_
  </body>_x000D_
</html>

Last thing to mention, if you rely on an external data source, it probably is good practise to provide a proper fallback value (otherwise you may see NaN or nothing on your site):

{{ (100 * (count/total) | number:0) || 0 }}

Sidenote: Depending on your specifications, you may even be able to be more precise with your fallbacks/define fallbacks on lower levels already (e.g. {{(100 * (count || 10)/ (total || 100) | number:2)}}). Though, this may not not always make sense..

I tried to set up toolbar like @Gabriele Mariotti, but I had some problem with title. So then I set order to

toolbar.setTitle("Title")
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.ic_good);

and it works.

You can use the parameter -f (or --file) and specify the path to your pom file, e.g. mvn -f /path/to/pom.xml

This runs maven "as if" it were in /path/to for the working directory.

I know it's an old question, but I just had to find solution for multiple rows update where multiple records had to updated with different values based on their IDs and I found that I can use a a scalar-subselect:

UPDATE PROJECT
  SET DEPTNO =
        (SELECT WORKDEPT FROM EMPLOYEE
           WHERE PROJECT.RESPEMP = EMPLOYEE.EMPNO)
  WHERE RESPEMP='000030'

(with WHERE optional, of course)

Also, I found that it is critical to specify that no NULL values would not be used in this update (in case not all records in first table have corresponding record in the second one), this way:

UPDATE PROJECT
  SET DEPTNO =
        (SELECT WORKDEPT FROM EMPLOYEE
           WHERE PROJECT.RESPEMP = EMPLOYEE.EMPNO)
  WHERE RESPEMP IN (SELECT EMPNO FROM EMPLOYEE)

If you have another program running in the JVM and you use System.exit, that second program will be closed, too. Imagine for example that you run a java job on a cluster node and that the java program that manages the cluster node runs in the same JVM. If the job would use System.exit it would not only quit the job but also "shut down the complete node". You would not be able to send another job to that cluster node since the management program has been closed accidentally.

Therefore, do not use System.exit if you want to be able to control your program from another java program within the same JVM.

Use System.exit if you want to close the complete JVM on purpose and if you want to take advantage of the possibilities that have been described in the other answers (e.g. shut down hooks: Java shutdown hook, non-zero return value for command line calls: How to get the exit status of a Java program in Windows batch file).

Also have a look at Runtime Exceptions: System.exit(num) or throw a RuntimeException from main?

You can also return all selected checkboxes value in comma separated string. This will also make it easier for you when you send it as a parameter to SQL

Here is a sample that return all selected checkboxes values that have the name "chkboxName" in comma separate string

And here is the javascript

function showSelectedValues()
{
  alert($("input[name=chkboxName]:checked").map(function () {
    return this.value;
  }).get().join(","));
}

Here is the HTML sample

<html>
  <head>
 </head>
 <body>
  <div>
   <input name="chkboxName" type="checkbox" value="one_name" checked>
   <input name="chkboxName" type="checkbox" value="one_name1">
   <input name="chkboxName" type="checkbox" value="one_name2">
  </div>  
 </body>
 </html>

Note that sort() operates on the array in place, so you only need to call

sort($a);
doSomething($a);

This will not work;

$a = sort($a);
doSomething($a);

If you want to go with the add-open option, here's a command to find which module provides which package ->

java --list-modules | tr @ " " | awk '{ print $1 }' | xargs -n1 java -d

the name of the module will be shown with the @ while the name of the packages without it

NOTE: tested with JDK 11

IMPORTANT: obviously is better than the provider of the package does not do the illegal access

Yes, your example would work fine.

As for exposing your classes, you can export a class just like anything else:

class Animal {...}
module.exports = Animal;

Or the shorter:

module.exports = class Animal {

};

Once imported into another module, then you can treat it as if it were defined in that file:

var Animal = require('./Animal');

class Cat extends Animal {
    ...
}

For showing result of batch file in text file, you can use

this command

chdir > test.txt

This command will redirect result to test.txt.

When you open test.txt you will found current path of directory in test.txt

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

To fix this error when using the online JSHint implementation:

• Click "CONFIGURE" (top of the middle column on the page)
• Enable "jQuery" (under the "ASSUME" section at the bottom)

CreateOrReplaceTempView will create a temporary view of the table on memory it is not presistant at this moment but you can run sql query on top of that . if you want to save it you can either persist or use saveAsTable to save.

first we read data in csv format and then convert to data frame and create a temp view

Reading data in csv format

val data = spark.read.format("csv").option("header","true").option("inferSchema","true").load("FileStore/tables/pzufk5ib1500654887654/campaign.csv")

printing the schema

data.printSchema

data.createOrReplaceTempView("Data")

Now we can run sql queries on top the table view we just created

  %sql select Week as Date,Campaign Type,Engagements,Country from Data order     by Date asc

Use:

sb.AppendLine();
sb.Append("\t");

for better portability. Environment.NewLine may not necessarily be \n; Windows uses \r\n, for example.

I had a problem using the defaultSelected property in the answer by @Jens Roland in jQuery v1.9.1. A more generic way (with many dependent selects) would be to put a data-default attribute in your dependent selects and then iterate through them when reseting.

<select id="name0" >
    <option value="">reset</option>
    <option value="1">Text 1</option>
    <option value="2">Text 2</option>
    <option value="3">Text 3</option>
</select>

<select id="name1" class="name" data-default="1">
    <option value="">select all</option>
    <option value="1" selected="true">Text 1</option>
    <option value="2">Text 2</option>
    <option value="3">Text 3</option>
</select>

<select id="name2" class="name" data-default="2">
    <option value="">select all</option>
    <option value="1">Text 1</option>
    <option value="2" selected="true">Text 2</option>
    <option value="3">Text 3</option>
</select>

And the javascript...

$('#name0').change(function(){
    if($('#name0').val() == '') {
        $('select.name').each(function(index){
          $(this).val($(this).data('default'))  
        })
    } else {
      $('select.name').val($('#name0').val() );
    }
});

See http://jsfiddle.net/8hvqN/ for a working version of the above.

Just a note in addition to the other answers.

If an initial value is supplied to reduce then sometimes its type must be specified, viz:-

a.reduce(fn, [])

may have to be

a.reduce<string[]>(fn, [])

or

a.reduce(fn, <string[]>[])

I had a similar problem with a physical device. The problem was related with the fact that the google app ( the search bar for google on top ) was disabled. After the first reboot launcher3 began failing. No matter how many cache/data cleaning I did, it kept failing. I reenabled it and launched it, so it appeared again on the screen and from that moment on, launcher3 was back to life.

I guess there mmust be some kind of dependency with this app.

You can see Main Answer for complete information about data binding errors and solutions. I will try to tell some important points below.

5 Tips that I use to solve binding issues.

Assuming that you have enabled data binding in build.gradle and you have converted your layout to binding layout.

First of all binding class auto generate when you convert layout to binding layout. Still sometimes it is not generated when background threads are not working. Here are some tips for you to resolve this.

(1) Name of generated class

Layout name is in snake_case activity_main.xml

Data binding class will be in PascalCase like ActivityMainBinding.

(2). Type full name of Binding class

I felt sometimes when you type ActivityMai..., then it does not show suggestion, but that does not mean class is not generated. In that case you should type full name of expected generated class. Like type ActivityMainBinding and it will show import popup. (That's what i faced many times.)

Still not getting import suggestion. Try manual import.

import <yourpackage>databinding.ActivityMainBinding;

(3). Rebuild Project

If still your class is not generated. (Some time when we paste layout file, then it happens). Then Rebuild Project from Build> Rebuild (Not Build or Make project). It will generate your data binding class. (Rebuild does Magic for me all times.)

(4) If you have created an <variable in your layout and it does not show up its setter and getter in data binding class, then follow 4th point.

(5) Still if your class is not generating then you should check if build is not failing due to an error in your layout file. Data binding class will generate with a successful build.

This is all what i do to solve my data binding errors. If you get any further issue, you can comment here.

In your PHP code you have set the incorrect port, this is what the code should be

<?php

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db     = 'test_db13';

The port in your code is set to 3360 when it should be 3306, however as this is the default port, you don't need to specify.

You can also check if the exact word is contained in a string. E.g.:

function containsWord(haystack, needle) {
    return (" " + haystack + " ").indexOf(" " + needle + " ") !== -1;
}

Usage:

containsWord("red green blue", "red"); // true
containsWord("red green blue", "green"); // true
containsWord("red green blue", "blue"); // true
containsWord("red green blue", "yellow"); // false

This is how jQuery does its hasClass method.

I wrote this into a dynamic method since I use lots of attributes throughout my application. Method:

public static dynamic GetAttribute(Type objectType, string propertyName, Type attrType)
    {
        //get the property
        var property = objectType.GetProperty(propertyName);

        //check for object relation
        return property.GetCustomAttributes().FirstOrDefault(x => x.GetType() == attrType);
    }

Usage:

var objectRelAttr = GetAttribute(typeof(Person), "Country", typeof(ObjectRelationAttribute));

var displayNameAttr = GetAttribute(typeof(Product), "Category", typeof(DisplayNameAttribute));

Hope this helps anyone

Is Nothing requires an object that has been assigned to the value Nothing. IsNothing() can take any variable that has not been initialized, including of numeric type. This is useful for example when testing if an optional parameter has been passed.

I think this table is short and usefull:

Supplier       ()    -> x
Consumer       x     -> ()
Callable       ()    -> x throws ex
Runnable       ()    -> ()
Function       x     -> y
BiFunction     x,y   -> z
Predicate      x     -> boolean
UnaryOperator  x1    -> x2
BinaryOperator x1,x2 -> x3

As said on the other answers, the appropriate option for this problem is a Runnable

SWIFT 4.x :

self.mConstraint.constant = 100.0
UIView.animate(withDuration: 0.3) {
        self.view.layoutIfNeeded()
}

Example with completion:

self.mConstraint.constant = 100
UIView.animate(withDuration: 0.3, animations: {
        self.view.layoutIfNeeded()
    }, completion: {res in
        //Do something
})

spool "D:\test\test.txt"

select

from  
  employee a  
inner join department b  
on  
(  
  a.dept_id = b.dept_id  
)  
;  
spool off  

This query will spool the sql result in D:\test\test.txt

Microsoft has listened to the cry for supporting installers (MSI) in Visual Studio and release the Visual Studio Installer Projects Extension. You can now create installers in VS2013, download the extension here from the visualstudiogallery.

You can use as well:

var x = "somestring";

console.log(x.split("")[0]); // output "s"

This should work with older browsers.

You can use the Grid CSS properties, is the most clear, clean and intuitive way structure your boxes.

#container{_x000D_
    display: grid;_x000D_
    grid-template-columns: 100px auto;_x000D_
    color:white;_x000D_
}_x000D_
#fixed{_x000D_
  background: red;_x000D_
  grid-column: 1;_x000D_
}_x000D_
#remaining{_x000D_
  background: green;_x000D_
  grid-column: 2;_x000D_
}

<div id="container">_x000D_
  <div id="fixed">Fixed</div>_x000D_
  <div id="remaining">Remaining</div>_x000D_
</div>

just do it as follows in your html write:

<button ng-click="going()">goto</button>

And in your controller, add $state as follows:

.controller('homeCTRL', function($scope, **$state**) {

$scope.going = function(){

$state.go('your route');

}

})

My particular issue was caused because I was working with directories that involved symbolic links (shortcuts). Consequently, trying java -jar ../../myJar.jar didn't work because I wasn't where I thought I was.

Disregarding relative file paths fixed it right up.

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>your.company</groupId>
    <artifactId>company-parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <distributionManagement>
        <repository>
            <id>nexus-site</id>
            <url>http://central_nexus/server</url>
        </repository>
    </distributionManagement>

</project>

This can be built, released, and deployed to your local nexus so everyone has access to its artifact.

Now for all projects which you wish to use it, simply include this section:

<parent>
  <groupId>your.company</groupId>
  <artifactId>company-parent</artifactId>
  <version>1.0.0</version>
</parent>

This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.

If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.

I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.

- pom.xml (aggregator)
    - project-parent
    - project-module1
    - project-module2

What you do with this structure is include your parent module in the aggregator and build everything with a mvn install from the root directory.

We use this exact solution at my organization and it has stood the test of time and worked quite well for us.

The statement basically does the following:

1. Creates a integer array of 'n' elements
2. Allocates the memory in HEAP memory of the process as you are using new operator to create the pointer
3. Returns a valid address (if the memory allocation for the required size if available at the point of execution of this statement)

It could depend on your framework. (for each of them could exist an easier solution).

But to answer your question: there are a lot of external libraries for this functionality. Look here how to use apache commons fileupload.

By the way, the structure you're giving as an example already exist in the Java base class library as java.awt.Point. It has x and y as public fields, check it out for yourself.

If you know what you're doing, and others in your team know about it, then it is okay to have public fields. But you shouldn't rely on it because they can cause headaches as in bugs related to developers using objects as if they were stack allocated structs (java objects are always sent to methods as references and not as copies).

1. option 1

   echo $(cat testfile)
   

2. Option 2

   tr ' ' '\n' < testfile
   

I had this issue in Android and I wrote a method similar to it-west.

Because I used AUTOINCREMENT primary keys in my tables, there was a table called sqlite_sequence. SQLite would crash when the routine tried to drop that table. I couldn't catch the exception either. Looking at https://www.sqlite.org/fileformat.html#internal_schema_objects, I learned that there could be several of these internal schema tables that I didn't want to drop. The documentation says that any of these tables have names beginning with sqlite_ so I wrote this method

private void dropAllUserTables(SQLiteDatabase db) {
    Cursor cursor = db.rawQuery("SELECT name FROM sqlite_master WHERE type='table'", null);
    //noinspection TryFinallyCanBeTryWithResources not available with API < 19
    try {
        List<String> tables = new ArrayList<>(cursor.getCount());

        while (cursor.moveToNext()) {
            tables.add(cursor.getString(0));
        }

        for (String table : tables) {
            if (table.startsWith("sqlite_")) {
                continue;
            }
            db.execSQL("DROP TABLE IF EXISTS " + table);
            Log.v(LOG_TAG, "Dropped table " + table);
        }
    } finally {
        cursor.close();
    }
}

SET Value

 declare Regione int;   
 set Regione=(select  id from users
 where id=1) ;
 select Regione ;

I find the below RE working fine for Date in the following format;

1. 14-11-2017
2. 14.11.2017
3. 14|11|2017

It can accept year from 2000-2099

Please do not forget to add $ at the end,if not it accept 14-11-201 or 20177

date="13-11-2017"

x=re.search("^([1-9] |1[0-9]| 2[0-9]|3[0-1])(.|-)([1-9] |1[0-2])(.|-|)20[0-9][0-9]$",date)

x.group()

output = '13-11-2017'

If you add double paranthesis to the ngModel reference you get a two-way binding to your model property. That property can then be read and used in the event handler. In my view that is the most clean approach.

<input type="checkbox" [(ngModel)]="myModel.property" (ngModelChange)="processChange()" />

Status 301 means that the resource (page) is moved permanently to a new location. The client/browser should not attempt to request the original location but use the new location from now on.

Status 302 means that the resource is temporarily located somewhere else, and the client/browser should continue requesting the original url.

I would suggest via Bitmap:

public void SaveImage(string base64)
{
    using (MemoryStream ms = new MemoryStream(Convert.FromBase64String(base64)))
    {
        using (Bitmap bm2 = new Bitmap(ms))
        {
            bm2.Save("SavingPath" + "ImageName.jpg");
        }
    }
}

For native code it's probably best to use Dependency Walker. It also possible to use dumpbin command line utility that comes with Visual Studio.

Ahah! Checkout the previous commit, then checkout the master.

git checkout HEAD^
git checkout -f master

There are multiple ways to do so, but Oracle and IBM say that using +, is a bad practice, because essentially every time you concatenate String, you end up creating additional objects in memory. It will utilize extra space in JVM, and your program may be out of space, or slow down.

Using StringBuilder or StringBuffer is best way to go with it. Please look at Nicolas Fillato's comment above for example related to StringBuffer.

String first = "I eat";  String second = "all the rats."; 
System.out.println(first+second);

The wp_trim_words function can limit the characters too by changing the $num_words variable. For anyone who might find useful.

<?php 
$id=58; 
$post = get_post($id); 
$content = apply_filters('the_content', $post->post_content); 

$customExcerpt = wp_trim_words( $content, $num_words = 26, $more = '' );
echo $customExcerpt;  
?>

you should check out this one: http://gitlist.org/.

It is written in PHP as you wanted it to be.

I recently had this problem myself, and once I determined which AppPool was causing the problem, the only way to resolve the issue was remove that app pool completly and create a new one for the site to use.

Every once in a while, and this isn't often, but every once in a while, there's a typo in your password. A subtle difference between an upper and lower case letter, for example. I went through many, many of these solutions.

I had simply mistyped the password, and it was saved to my browser, so I didn't think to check it again.

Since this error CAN be caused by a missed password, just double-check before you go on this quest.

Here's a regex-only solution, which seems to work with any OS path on any OS.

No other module is needed, and no preprocessing is needed either :

import re

def extract_basename(path):
  """Extracts basename of a given path. Should Work with any OS Path on any OS"""
  basename = re.search(r'[^\\/]+(?=[\\/]?$)', path)
  if basename:
    return basename.group(0)


paths = ['a/b/c/', 'a/b/c', '\\a\\b\\c', '\\a\\b\\c\\', 'a\\b\\c',
         'a/b/../../a/b/c/', 'a/b/../../a/b/c']

print([extract_basename(path) for path in paths])
# ['c', 'c', 'c', 'c', 'c', 'c', 'c']


extra_paths = ['C:\\', 'alone', '/a/space in filename', 'C:\\multi\nline']

print([extract_basename(path) for path in extra_paths])
# ['C:', 'alone', 'space in filename', 'multi\nline']

Update:

If you only want a potential filename, if present (i.e., /a/b/ is a dir and so is c:\windows\), change the regex to: r'[^\\/]+(?![\\/])$' . For the "regex challenged," this changes the positive forward lookahead for some sort of slash to a negative forward lookahead, causing pathnames that end with said slash to return nothing instead of the last sub-directory in the pathname. Of course there is no guarantee that the potential filename actually refers to a file and for that os.path.is_dir() or os.path.is_file() would need to be employed.

This will match as follows:

/a/b/c/             # nothing, pathname ends with the dir 'c'
c:\windows\         # nothing, pathname ends with the dir 'windows'
c:hello.txt         # matches potential filename 'hello.txt'
~it_s_me/.bashrc    # matches potential filename '.bashrc'
c:\windows\system32 # matches potential filename 'system32', except
                    # that is obviously a dir. os.path.is_dir()
                    # should be used to tell us for sure

The regex can be tested here.

Verified: it works well in Docker 1.7.0.

Don't specify --pull=true when running the docker build command

From this thread on reference locally-built image using FROM at dockerfile:

If you want use the local image as the base image, pass without the option --pull=true
--pull=true will always attempt to pull a newer version of the image.

Use Autohotkey to make a macro. AHK is free and dead simple to install. www.autohotkey.com

You could assign the macro to, say, alt-p:

!p::send print(){Left}

That will make alt-p put out print() and move your cursor to inside the parens.

Or, even better, to directly solve your problem, you define an autoreplace and limit its scope to when the open file has the .py extension:

#IfWinActive .py            ;;; scope limiter
:b*:print ::print(){Left}   ;;; I forget what b* does. The rest should be clear 
#IfWinActive                ;;; remove the scope limitation

This is a guaranteed, painless, transparent solution.

You might looking for the placeholder attribute which will display a grey text in the input field while empty.

From Mozilla Developer Network:

A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the type attribute is text, search, tel, url or email; otherwise it is ignored.

However as it's a fairly 'new' tag (from the HTML5 specification afaik) you might want to to browser testing to make sure your target audience is fine with this solution.
(If not tell tell them to upgrade browser 'cause this tag works like a charm ;o) )

And finally a mini-fiddle to see it directly in action: http://jsfiddle.net/LnU9t/

Edit: Here is a plain jQuery solution which will also clear the input field if an escape keystroke is detected: http://jsfiddle.net/3GLwE/

A Bcrypt hash can be stored in a BINARY(40) column.

BINARY(60), as the other answers suggest, is the easiest and most natural choice, but if you want to maximize storage efficiency, you can save 20 bytes by losslessly deconstructing the hash. I've documented this more thoroughly on GitHub: https://github.com/ademarre/binary-mcf

Bcrypt hashes follow a structure referred to as modular crypt format (MCF). Binary MCF (BMCF) decodes these textual hash representations to a more compact binary structure. In the case of Bcrypt, the resulting binary hash is 40 bytes.

Gumbo did a nice job of explaining the four components of a Bcrypt MCF hash:

$<id>$<cost>$<salt><digest>

Decoding to BMCF goes like this:

1. $<id>$ can be represented in 3 bits.
2. <cost>$, 04-31, can be represented in 5 bits. Put these together for 1 byte.
3. The 22-character salt is a (non-standard) base-64 representation of 128 bits. Base-64 decoding yields 16 bytes.
4. The 31-character hash digest can be base-64 decoded to 23 bytes.
5. Put it all together for 40 bytes: 1 + 16 + 23

You can read more at the link above, or examine my PHP implementation, also on GitHub.

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

As others have answered, you probably have a DATETIME (or other variation) column and not a DATE datatype.

Here's a condition that works for all, including DATE:

SELECT * 
FROM xxx 
WHERE dates >= '20121026' 
  AND dates <  '20121028'    --- one day after 
                             --- it is converted to '2012-10-28 00:00:00.000'
 ;

@Aaron Bertrand has blogged about this at: What do BETWEEN and the devil have in common?

Sure:

var query = grades.GroupBy(student => student.Name)
                  .Select(group => 
                        new { Name = group.Key,
                              Students = group.OrderByDescending(x => x.Grade) })
                  .OrderBy(group => group.Students.First().Grade);

Note that you can get away with just taking the first grade within each group after ordering, because you already know the first entry will be have the highest grade.

Then you could display them with:

foreach (var group in query)
{
    Console.WriteLine("Group: {0}", group.Name);
    foreach (var student in group.Students)
    {
        Console.WriteLine("  {0}", student.Grade);
    }
}

Try adding a style="width:100%;" to the img tag. That way the image will fill up the entire width of the page, thus scaling down if the image is larger than the viewport.

The following should work with the latest version of Apache common codec

byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw==");
System.out.println(new String(decodedBytes));

and for encoding

byte[] encodedBytes = Base64.getEncoder().encode(decodedBytes);
System.out.println(new String(encodedBytes));

In my case, the error occurred because I had not initialized the select list in the controller like this:

viewModel.MySelectList = new List<System.Web.Mvc.SelectListItem>();

As none of the existing answers made this clear to me, I post this. Perhaps it helps anybody.

You need to export the User.name field so that the json package can see it. Rename the name field to Name.

package main

import (
    "fmt"
    "encoding/json"
)

type User struct {
    Name string
}

func main() {
    user := &User{Name: "Frank"}
    b, err := json.Marshal(user)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

Output:

{"Name":"Frank"}

A slight tangent -- if you want to parse and evaluate an entire expression string which contains (nested!) functions, consider NCalc (http://ncalc.codeplex.com/ and nuget)

Ex. slightly modified from the project documentation:

// the expression to evaluate, e.g. from user input (like a calculator program, hint hint college students)
var exprStr = "10 + MyFunction(3, 6)";
Expression e = new Expression(exprString);

// tell it how to handle your custom function
e.EvaluateFunction += delegate(string name, FunctionArgs args) {
        if (name == "MyFunction")
            args.Result = (int)args.Parameters[0].Evaluate() + (int)args.Parameters[1].Evaluate();
    };

// confirm it worked
Debug.Assert(19 == e.Evaluate());

And within the EvaluateFunction delegate you would call your existing function.

In my case, LoginActivity was closed as well. As a result,

Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK

did not help.

However, setting

Intent.FLAG_ACTIVITY_NEW_TASK

helped me.

I'm not sure @cmbuckley answer is showing the full picture. What I read is:

Unless the cookie's attributes indicate otherwise, the cookie is returned only to the origin server (and not, for example, to any subdomains), and it expires at the end of the current session (as defined by the user agent). User agents ignore unrecognized cookie.

RFC 6265

Also

8.6.  Weak Integrity

   Cookies do not provide integrity guarantees for sibling domains (and
   their subdomains).  For example, consider foo.example.com and
   bar.example.com.  The foo.example.com server can set a cookie with a
   Domain attribute of "example.com" (possibly overwriting an existing
   "example.com" cookie set by bar.example.com), and the user agent will
   include that cookie in HTTP requests to bar.example.com.  In the
   worst case, bar.example.com will be unable to distinguish this cookie
   from a cookie it set itself.  The foo.example.com server might be
   able to leverage this ability to mount an attack against
   bar.example.com.

To me that means you can protect cookies from being read by subdomain/domain but cannot prevent writing cookies to the other domains. So somebody may rewrite your site cookies by controlling another subdomain visited by the same browser. Which might not be a big concern.

# redirects STDOUT to the file in question
for line in fileinput.input(files, inplace = 1): 
      print line.replace("foo", "bar"),

I know it's an old post but I'd like to contribute with a class I've created based on Jeremy Ruten's answer and improved with suggestions in comments:

    class RandomString
    {
      private static $characters = 'abcdefghijklmnopqrstuvwxyz0123456789';
      private static $string;
      private static $length = 8; //default random string length

      public static function generate($length = null)
      {

        if($length){
          self::$length = $length;
        }

        $characters_length = strlen(self::$characters) - 1;

        for ($i = 0; $i < self::$length; $i++) {
          self::$string .= self::$characters[mt_rand(0, $characters_length)];
        }

        return self::$string;

      }

    }

I am shamelessly copying the excerpts from man page of top

VIRT -- Virtual Image (kb) The total amount of virtual memory used by the task. It includes all code, data and shared libraries plus pages that have been swapped out and pages that have been mapped but not used.

SWAP -- Swapped size (kb) Memory that is not resident but is present in a task. This is memory that has been swapped out but could include additional non- resident memory. This column is calculated by subtracting physical memory from virtual memory

Editing .sln and .csproj is not always that easy or desirable. Once you get the error list you can see what projects have missing packages (also, the References node usually indicate that there are missing assemblies unless packages are source code, resources, images, or just text-based ones).

Removing and then adding the packages is not a good idea unless you use the latest version of the package. Otherwise be prepared for surprises, not always pleasant ones.

If, say, the package is EntityFramework then from NuGet gallery you get the latest version which at the time of writing this comment it is 6.1.3.

So, maybe the safest way to handle the situation is to restore the missing packages one by one. Yes, a bit painful exercise but chasing subtle bugs due to different package version maybe much more unpleasant.

Having this said, and let again EntityFramework be the missing package, you can issue the following command in the Package-Manager Console:

PM> Install-Package EntityFramework -Version 6.0.1 

This will install the correct version, that is 6.0.1, that is the one that is specified in packages.config:

    <?xml version="1.0" encoding="utf-8"?>
    <packages>
      <package id="EntityFramework" version="6.0.1" targetFramework="net451" />
    </packages>

I have a 7GB SQLite database. To perform a particular query with an inner join takes 2.6s In order to speed this up I tried adding indexes. Depending on which index(es) I added, sometimes the query went down to 0.1s and sometimes it went UP to as much as 7s. I think the problem in my case was that if a column is highly duplicate then adding an index degrades performance :(

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

Hope this helps but please let me know if you need more details.

You can sort a int array with Arrays.sort( array ).

There is an alternative way to change the key of an array element when working with a full array - without changing the order of the array. It's simply to copy the array into a new array.

For instance, I was working with a mixed, multi-dimensional array that contained indexed and associative keys - and I wanted to replace the integer keys with their values, without breaking the order.

I did so by switching key/value for all numeric array entries - here: ['0'=>'foo']. Note that the order is intact.

<?php
$arr = [
    'foo',
    'bar'=>'alfa',
    'baz'=>['a'=>'hello', 'b'=>'world'],
];

foreach($arr as $k=>$v) {
    $kk = is_numeric($k) ? $v : $k;
    $vv = is_numeric($k) ? null : $v;
    $arr2[$kk] = $vv;
}

print_r($arr2);

Output:

Array (
    [foo] => 
    [bar] => alfa
    [baz] => Array (
            [a] => hello
            [b] => world
        )
)

I have created a data frame in a for loop with the help of a temporary empty data frame. Because for every iteration of for loop, a new data frame will be created thereby overwriting the contents of previous iteration.

Hence I need to move the contents of the data frame to the empty data frame that was created already. It's as simple as that. We just need to use .append function as shown below :

temp_df = pd.DataFrame() #Temporary empty dataframe
for sent in Sentences:
    New_df = pd.DataFrame({'words': sent.words}) #Creates a new dataframe and contains tokenized words of input sentences
    temp_df = temp_df.append(New_df, ignore_index=True) #Moving the contents of newly created dataframe to the temporary dataframe

Outside the for loop, you can copy the contents of the temporary data frame into the master data frame and then delete the temporary data frame if you don't need it

After the last Firefox update we had the same session timeout issue and the following setting helped to resolve it.

We can control it with network.http.response.timeout parameter.

1. Open Firefox and type in ‘about:config’ in the address bar and press Enter.
2. Click on the "I'll be careful, I promise!" button.
3. Type ‘timeout’ in the search box and network.http.response.timeout parameter will be displayed.
4. Double-click on the network.http.response.timeout parameter and enter the time value (it is in seconds) that you don't want your session not to timeout, in the box.

I solved the problem by cat'ing all the pems together:

cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD

(keytool didn't know what to do with a PKCS7 formatted key)

I got all the pems from letsencrypt

works

$('a[href*=#]').each(function () {
    $(this).attr('href', $(this).attr('href').replace('#', '#_'));
    $(this).on( "click", function() {

        var hashname = $(this).attr('href').replace('#_', '');

        if($(this).attr('href') == "#_") {
            $('html, body').animate({ scrollTop: 0 }, 300);
        }
        else {
            var target = $('a[name="' + hashname + '"], #' + hashname),
                targetOffset = target.offset().top;
            if(targetOffset >= 1) {
                $('html, body').animate({ scrollTop: targetOffset-60 }, 300);
            }
        }
    });
});

If you are behind a proxy, you must do some extra configuration steps before starting the installation. You must set the environment variable http_proxy to the proxy address. Using bash this is accomplished with the command

export http_proxy="http://user:[email protected]:port/" 

You can also provide the

--proxy=[user:pass@]url:port 

parameter to pip. The [user:pass@] portion is optional.

In case you are using NodeJS/Express as back-end and ReactJS/axios as front-end within a development environment in MacOS, you need to run both sides under https. Below is what it finally worked for me (after many hours of deep dive & testing):

Step 1: Create an SSL certificate

Just follow the steps from How to get HTTPS working on your local development environment in 5 minutes

You will end up with a couple of files to be used as credentials to run the https server and ReactJS web:

server.key & server.crt

You need to copy them in the root folders of both the front and back ends (in a Production environment, you might consider copying them in ./ssh for the back-end).

Step 2: Back-end setup

I read a lot of answers proposing the use of 'cors' package or even setting ('Access-Control-Allow-Origin', '*'), which is like saying: "Hackers are welcome to my website". Just do like this:

import express from 'express';
const emailRouter = require('./routes/email');  // in my case, I was sending an email through a form in ReactJS
const fs = require('fs');
const https = require('https');

const app = express();
const port = 8000;

// CORS (Cross-Origin Resource Sharing) headers to support Cross-site HTTP requests
app.all('*', (req, res, next) => {
    res.header("Access-Control-Allow-Origin", "https://localhost:3000");
    next();
});

// Routes definition
app.use('/email', emailRouter);

// HTTPS server
const credentials = {
  key: fs.readFileSync('server.key'),
  cert: fs.readFileSync('server.crt')
};

const httpsServer = https.createServer(credentials, app);
httpsServer.listen(port, () => {
    console.log(`Back-end running on port ${port}`);
});

In case you want to test if the https is OK, you can replace the httpsServer constant by the one below:

https.createServer(credentials, (req: any, res: any) => {
  res.writeHead(200);
  res.end("hello world from SSL\n");
}).listen(port, () => {
  console.log(`HTTPS server listening on port ${port}...`);
});

And then access it from a web browser: https://localhost:8000/

Step 3: Front-end setup

This is the axios request from the ReactJS front-end:

    await axios.get(`https://localhost:8000/email/send`, {
        params: {/* whatever data you want to send */ },
        headers: {
            'Content-Type': 'application/json',
        }
    })

And now, you need to launch your ReactJS web in https mode using the credentials for SSL we already created. Type this in your MacOS terminal:

HTTPS=true SSL_CRT_FILE=server.crt SSL_KEY_FILE=server.key npm start

At this point, you are sending a request from an https connection at port 3000 from your front-end, to be received by an https connection at port 8000 by your back-end. CORS should be happy with this ;)

If you're a C# / Java / C++ / Ruby / Python / Pick-A-Language-From-This-Century developer and you want to call your function with commas, because that's what you've always done, then you need something like this:

$myModule = New-Module -ascustomobject { 
    function test($arg1, $arg2) { 
        echo "arg1 = $arg1, and arg2 = $arg2"
    }
}

Now call:

$myModule.test("ABC", "DEF")

and you'll see

arg1 = ABC, and arg2 = DEF

You did not do anything wrong here, it will any other thing that is overriding the image size.

You can check this working fiddle.

And in this fiddle I have alter the image size using %, and it is working.

Also try using this code:

<img src="image.jpg" style="width: 50%; height: 50%"/>?

Here is the example fiddle.

Tree like structure in Notepad++ without plugin

Download Notepad++ 6.8.8 & then follow step below :

Notepad++ -> View-> Project-> choose Panel 1 OR Panel 2 OR Panel 3 ->

It will create a sub part Wokspace on the left side -> Right click on Workspace & click Add Project -> Again right click on Project which is created recently -> And click on Add Files From Directory.

This is it. Enjoy

I have another solution. If Alpha and Beta are your only extra class then why not make a static variable with the image of the class.

Like in Alpha class :

public class Alpha{
        public static Alpha alpha;
        public Alpha(){
                this.alpha = this;
}

Now you you can call the function in Beta class by just using these lines :

new Alpha();
Alpha.alpha.DoSomethingAlpha();

On Ubuntu:

Clearly there are lots of different ways of getting the same results, your question seems to be what is an efficient way of getting the last results in each group in MySQL. If you are working with huge amounts of data and assuming you are using InnoDB with even the latest versions of MySQL (such as 5.7.21 and 8.0.4-rc) then there might not be an efficient way of doing this.

We sometimes need to do this with tables with even more than 60 million rows.

For these examples I will use data with only about 1.5 million rows where the queries would need to find results for all groups in the data. In our actual cases we would often need to return back data from about 2,000 groups (which hypothetically would not require examining very much of the data).

I will use the following tables:

CREATE TABLE temperature(
  id INT UNSIGNED NOT NULL AUTO_INCREMENT, 
  groupID INT UNSIGNED NOT NULL, 
  recordedTimestamp TIMESTAMP NOT NULL, 
  recordedValue INT NOT NULL,
  INDEX groupIndex(groupID, recordedTimestamp), 
  PRIMARY KEY (id)
);

CREATE TEMPORARY TABLE selected_group(id INT UNSIGNED NOT NULL, PRIMARY KEY(id)); 

The temperature table is populated with about 1.5 million random records, and with 100 different groups. The selected_group is populated with those 100 groups (in our cases this would normally be less than 20% for all of the groups).

As this data is random it means that multiple rows can have the same recordedTimestamps. What we want is to get a list of all of the selected groups in order of groupID with the last recordedTimestamp for each group, and if the same group has more than one matching row like that then the last matching id of those rows.

If hypothetically MySQL had a last() function which returned values from the last row in a special ORDER BY clause then we could simply do:

SELECT 
  last(t1.id) AS id, 
  t1.groupID, 
  last(t1.recordedTimestamp) AS recordedTimestamp, 
  last(t1.recordedValue) AS recordedValue
FROM selected_group g
INNER JOIN temperature t1 ON t1.groupID = g.id
ORDER BY t1.recordedTimestamp, t1.id
GROUP BY t1.groupID;

which would only need to examine a few 100 rows in this case as it doesn't use any of the normal GROUP BY functions. This would execute in 0 seconds and hence be highly efficient. Note that normally in MySQL we would see an ORDER BY clause following the GROUP BY clause however this ORDER BY clause is used to determine the ORDER for the last() function, if it was after the GROUP BY then it would be ordering the GROUPS. If no GROUP BY clause is present then the last values will be the same in all of the returned rows.

However MySQL does not have this so let's look at different ideas of what it does have and prove that none of these are efficient.

Example 1

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue
FROM selected_group g
INNER JOIN temperature t1 ON t1.id = (
  SELECT t2.id
  FROM temperature t2 
  WHERE t2.groupID = g.id
  ORDER BY t2.recordedTimestamp DESC, t2.id DESC
  LIMIT 1
);

This examined 3,009,254 rows and took ~0.859 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 2

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM temperature t1
INNER JOIN ( 
  SELECT max(t2.id) AS id   
  FROM temperature t2
  INNER JOIN (
    SELECT t3.groupID, max(t3.recordedTimestamp) AS recordedTimestamp
    FROM selected_group g
    INNER JOIN temperature t3 ON t3.groupID = g.id
    GROUP BY t3.groupID
  ) t4 ON t4.groupID = t2.groupID AND t4.recordedTimestamp = t2.recordedTimestamp
  GROUP BY t2.groupID
) t5 ON t5.id = t1.id;

This examined 1,505,331 rows and took ~1.25 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 3

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM temperature t1
WHERE t1.id IN ( 
  SELECT max(t2.id) AS id   
  FROM temperature t2
  INNER JOIN (
    SELECT t3.groupID, max(t3.recordedTimestamp) AS recordedTimestamp
    FROM selected_group g
    INNER JOIN temperature t3 ON t3.groupID = g.id
    GROUP BY t3.groupID
  ) t4 ON t4.groupID = t2.groupID AND t4.recordedTimestamp = t2.recordedTimestamp
  GROUP BY t2.groupID
)
ORDER BY t1.groupID;

This examined 3,009,685 rows and took ~1.95 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 4

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue
FROM selected_group g
INNER JOIN temperature t1 ON t1.id = (
  SELECT max(t2.id)
  FROM temperature t2 
  WHERE t2.groupID = g.id AND t2.recordedTimestamp = (
      SELECT max(t3.recordedTimestamp)
      FROM temperature t3 
      WHERE t3.groupID = g.id
    )
);

This examined 6,137,810 rows and took ~2.2 seconds on 5.7.21 and slightly longer on 8.0.4-rc

Example 5

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue
FROM (
  SELECT 
    t2.id, 
    t2.groupID, 
    t2.recordedTimestamp, 
    t2.recordedValue, 
    row_number() OVER (
      PARTITION BY t2.groupID ORDER BY t2.recordedTimestamp DESC, t2.id DESC
    ) AS rowNumber
  FROM selected_group g 
  INNER JOIN temperature t2 ON t2.groupID = g.id
) t1 WHERE t1.rowNumber = 1;

This examined 6,017,808 rows and took ~4.2 seconds on 8.0.4-rc

Example 6

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM (
  SELECT 
    last_value(t2.id) OVER w AS id, 
    t2.groupID, 
    last_value(t2.recordedTimestamp) OVER w AS recordedTimestamp, 
    last_value(t2.recordedValue) OVER w AS recordedValue
  FROM selected_group g
  INNER JOIN temperature t2 ON t2.groupID = g.id
  WINDOW w AS (
    PARTITION BY t2.groupID 
    ORDER BY t2.recordedTimestamp, t2.id 
    RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
  )
) t1
GROUP BY t1.groupID;

This examined 6,017,908 rows and took ~17.5 seconds on 8.0.4-rc

Example 7

SELECT t1.id, t1.groupID, t1.recordedTimestamp, t1.recordedValue 
FROM selected_group g
INNER JOIN temperature t1 ON t1.groupID = g.id
LEFT JOIN temperature t2 
  ON t2.groupID = g.id 
  AND (
    t2.recordedTimestamp > t1.recordedTimestamp 
    OR (t2.recordedTimestamp = t1.recordedTimestamp AND t2.id > t1.id)
  )
WHERE t2.id IS NULL
ORDER BY t1.groupID;

This one was taking forever so I had to kill it.

This is not a code issue. It is your default IE settings

To change the "always open" setting:

1. In Windows Explorer, click on the "Tools" menu, choose "Folder options"
2. In the window that appears, click on the "File Types" tab, and scroll through the list until you find the file extension you want to change (they're in alphabetical order). For example, if Internet Explorer always tries to open .zip files, scroll through the list until you find the entry for "zip".
3. Click on the file type, then the "Advanced" button.
4. Check the "Confirm after download" box, then click OK > Close.

EDIT: If you ask me , instead of making any changes in the code i would add the following text "Internet Explorer users: To download file, "Rightclick" the link and hit "Save target as" to download the file."

EDIT 2: THIS solution will work perfectly for you. Its a solution i just copied from the other answer. Im not trying to pass it off as my own

Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"

However you must make sure that you specify the type of file(s) you allow. You have mentioned in your post that you want this for any type of file. This will be an issue.

For ex. If your site has images and if the end user clicks these images then they will be downloaded on his computer instead of opening in a new page. Got the point. So you need to specify the file extensions.

Maybe

df <- do.call("cbind", list(df, rep(list(NA),length(namevector))))
colnames(df)[-1*(1:(ncol(df) - length(namevector)))] <- namevector

I had to validate an empty object check as below

ex:

<div  data-ng-include="'/xx/xx/xx/regtabs.html'" data-ng-if =
    "$parent.$eval((errors | json) != '{}')" >
</div>

The error is my scope object, it is being defined in my controller as $scope.error = {};

I was also having the trouble to route to a different view using navlink.

My implementation was as follows and works perfectly;

<NavLink tag='li'>
  <div
    onClick={() =>
      this.props.history.push('/admin/my- settings')
    }
  >
    <DropdownItem className='nav-item'>
      Settings
    </DropdownItem>
  </div>
</NavLink>

Wrap it with a div, assign the onClick handler to the div. Use the history object to push a new view.

The best way to test if a registry value exists is to do just that - test for its existence. This is a one-liner, even if it's a little hard to read.

PS C:> (Get-ItemProperty $regkey).PSObject.Properties.Name -contains $name

If you actually look up its data, then you run into the complication of how Powershell interprets 0.

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

the pom.xml for the project I have doesn't have this "http://repo1.maven.org/myurlhere" anywhere in it

All projects have http://repo1.maven.org/ declared as <repository> (and <pluginRepository>) by default. This repository, which is called the central repository, is inherited like others default settings from the "Super POM" (all projects inherit from the Super POM). So a POM is actually a combination of the Super POM, any parent POMs and the current POM. This combination is called the "effective POM" and can be printed using the effective-pom goal of the Maven Help plugin (useful for debugging).

And indeed, if you run:

mvn help:effective-pom

You'll see at least the following:

  <repositories>
    <repository>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>Maven Repository Switchboard</name>
      <url>http://repo1.maven.org/maven2</url>
    </repository>
  </repositories>
  <pluginRepositories>
    <pluginRepository>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>Maven Plugin Repository</name>
      <url>http://repo1.maven.org/maven2</url>
    </pluginRepository>
  </pluginRepositories>

it has the absolute url where the maven repo is for the project but maven is still trying to download from the general maven repo

Maven will try to find dependencies in all repositories declared, including in the central one which is there by default as we saw. But, according to the trace you are showing, you only have one repository defined (the central repository) or maven would print something like this:

Reason: Unable to download the artifact from any repository

  url.project:project:pom:x.x

from the specified remote repositories:
  central (http://repo1.maven.org/),
  another-repository (http://another/repository)

So, basically, maven is unable to find the url.project:project:pom:x.x because it is not available in central.

But without knowing which project you've checked out (it has maybe specific instructions) or which dependency is missing (it can maybe be found in another repository), it's impossible to help you further.

The easiest way is to put the declaration and definition in the same file, but it may cause over-sized excutable file. E.g.

class Foo
{
public:
template <typename T> void some_method(T t) {//...}
}

Also, it is possible to put template definition in the separate files, i.e. to put them in .cpp and .h files. All you need to do is to explicitly include the template instantiation to the .cpp files. E.g.

// .h file
class Foo
{
public:
template <typename T> void some_method(T t);
}

// .cpp file
//...
template <typename T> void Foo::some_method(T t) 
{//...}
//...

template void Foo::some_method<int>(int);
template void Foo::some_method<double>(double);

I would just raise ValueError, unless you need a more specific exception..

def import_to_orm(name, save=False, recurse=False):
    if recurse and not save:
        raise ValueError("save must be True if recurse is True")

There's really no point in doing class BadValueError(ValueError):pass - your custom class is identical in use to ValueError, so why not use that?

Using is_numeric or intval is likely the best way to validate a number here, but to answer your question you could try using preg_replace instead. This example removes all non-numeric characters:

$output = preg_replace( '/[^0-9]/', '', $string );

Use PHP's strip_tags() function.

For example:

$businessDesc = strip_tags($row_get_Business['business_description']);
$businessDesc = substr($businessDesc, 0, 110);


print($businessDesc);

Here's another approach that runs slower (about 1000ms) than the above answer, but has an interesting idea :-)

Instead of iterating through each property chain, it just picks the last property and uses a look-up-table for the rest to store the intermediate results. This look-up-table will be iterated until there are no property chains left and all values reside on uncocatenated properties.

JSON.unflatten = function(data) {
    "use strict";
    if (Object(data) !== data || Array.isArray(data))
        return data;
    var regex = /\.?([^.\[\]]+)$|\[(\d+)\]$/,
        props = Object.keys(data),
        result, p;
    while(p = props.shift()) {
        var m = regex.exec(p),
            target;
        if (m.index) {
            var rest = p.slice(0, m.index);
            if (!(rest in data)) {
                data[rest] = m[2] ? [] : {};
                props.push(rest);
            }
            target = data[rest];
        } else {
            target = result || (result = (m[2] ? [] : {}));
        }
        target[m[2] || m[1]] = data[p];
    }
    return result;
};

It currently uses the data input parameter for the table, and puts lots of properties on it - a non-destructive version should be possible as well. Maybe a clever lastIndexOf usage performs better than the regex (depends on the regex engine).

See it in action here.

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

default_scope

This works for Rails 4+:

class Book < ActiveRecord::Base
  default_scope { order(created_at: :desc) }
end

For Rails 2.3, 3, you need this instead:

default_scope order('created_at DESC')

For Rails 2.x:

default_scope :order => 'created_at DESC'

Where created_at is the field you want the default sorting to be done on.

Note: ^ASC is the code to use for Ascending and _DESC is for descending (desc, NOT dsc !).

scope

Once you're used to that you can also use scope:

class Book < ActiveRecord::Base
  scope :confirmed, :conditions => { :confirmed => true }
  scope :published, :conditions => { :published => true }
end

For Rails 2 you need named_scope.

:published scope gives you Book.published instead of Book.find(:published => true).

Since Rails 3 you can 'chain' those methods together by concatenating them with periods between them, so with the above scopes you can now use Book.published.confirmed.

With this method, the query is not actually executed until actual results are needed (lazy evaluation), so 7 scopes could be chained together but only resulting in 1 actual database query, to avoid performance problems from executing 7 separate queries.

You can use a passed in parameter such as a date or a user_id (something that will change at run-time and so will need that 'lazy evaluation', with a lambda, like this:

scope :recent_books, lambda 
  { |since_when| where("created_at >= ?", since_when) }
  # Note the `where` is making use of AREL syntax added in Rails 3.

Finally you can disable default scope with:

Book.with_exclusive_scope { find(:all) } 

or even better:

Book.unscoped.all

which will disable any filter (conditions) or sort (order by).

Note that the first version works in Rails2+ whereas the second (unscoped) is only for Rails3+

So ... if you're thinking, hmm, so these are just like methods then..., yup, that's exactly what these scopes are!
They are like having def self.method_name ...code... end but as always with ruby they are nice little syntactical shortcuts (or 'sugar') to make things easier for you!

In fact they are Class level methods as they operate on the 1 set of 'all' records.

Their format is changing however, with rails 4 there are deprecation warning when using #scope without passing a callable object. For example scope :red, where(color: 'red') should be changed to scope :red, -> { where(color: 'red') }.

As a side note, when used incorrectly, default_scope can be misused/abused.
This is mainly about when it gets used for actions like where's limiting (filtering) the default selection (a bad idea for a default) rather than just being used for ordering results.
For where selections, just use the regular named scopes. and add that scope on in the query, e.g. Book.all.published where published is a named scope.

In conclusion, scopes are really great and help you to push things up into the model for a 'fat model thin controller' DRYer approach.

This worked for me.

const requestOptions = {
method: 'GET',
headers: { 'Content-Type': 'application/json' }
};

fetch(`${url}`, requestOptions)
.then((res) => {
    return res.blob();
})
.then((blob) => {
    const href = window.URL.createObjectURL(blob);
    const link = document.createElement('a');
    link.href = href;
    link.setAttribute('download', 'config.json'); //or any other extension
    document.body.appendChild(link);
    link.click();
})
.catch((err) => {
    return Promise.reject({ Error: 'Something Went Wrong', err });
})

You can make sure that the object in question is stringified before passing it to parse function by simply using JSON.stringify() .

Updated your line below,

JSON.parse(JSON.stringify({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false}));

or if you have JSON stored in some variable:

JSON.parse(JSON.stringify(yourJSONobject));

This works for me and is reusable.

function isThisDayAWeekend($date) {

    $timestamp = strtotime($date);

    $weekday= date("l", $timestamp );

    if ($weekday =="Saturday" OR $weekday =="Sunday") { return true; } 
    else {return false; }

}

Are you looking for something like this?

SELECT CASE WHEN LEFT(created_ts, 1) LIKE '[0-9]' 
            THEN CONVERT(VARCHAR(10), CONVERT(datetime, created_ts,   1), 101)
            ELSE CONVERT(VARCHAR(10), CONVERT(datetime, created_ts, 109), 101)
      END created_ts
  FROM table1

Output:

| CREATED_TS |
|------------|
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |
| 11/29/2012 |
| 11/16/2011 |
| 02/20/2012 |

Here is SQLFiddle demo

Double quotes are used for strings (i.e., "this is a string") and single quotes are used for a character (i.e., 'a', 'b' or 'c'). Depending on the programming language and context, you can get away with using double quotes for a character but not single quotes for a string.

HTML doesn't care about which one you use. However, if you're writing HTML inside a PHP script, you should stick with double quotes as you will need to escape them (i.e., \"whatever\") to avoid confusing yourself and PHP.

df.index

• outputs the row names as pandas Index object.

list(df.index)

• casts to a list.

df.index['Row 2':'Row 5']

• supports label slicing similar to columns.

I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.

I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.

1. Go to the "Manage NuGet Packages"
2. Select the Installed Package "Microsoft ASP.NET Web API 2.1"
3. Click Manage and check the projects that I manually added before.

this way many people detect session has expired or not. the below code may help u.

protected void Page_Init(object sender, EventArgs e)
    {
        if (Context.Session != null)
        {
            if (Session.IsNewSession)
            {
                HttpCookie newSessionIdCookie = Request.Cookies["ASP.NET_SessionId"];
                if (newSessionIdCookie != null)
                {
                    string newSessionIdCookieValue = newSessionIdCookie.Value;
                    if (newSessionIdCookieValue != string.Empty)
                    {
                        // This means Session was timed Out and New Session was started
                        Response.Redirect("Login.aspx");
                    }
                }
            }
        }
    }

I heard of RTM (The RT FAQ Manager). Never used it, however.

There is a difference of context between ES5 and ES6 class. So, there will be a little difference between the implementations as well.

Here is the ES5 version:

var Counter = React.createClass({
    getInitialState: function() { return { count : 1 }; },
    delta: function() {
        this.setState({
            count : this.state.count++
        });
    },
    render: function() {
        return (
            <div>
              <h1>{this.state.count}</h1>
              <button onClick={this.delta}>+</button>
            </div>
            );
    }
});

and here is the ES6 version:

class Counter extends React.Component {
    constructor(props) {
        super(props);
        this.state = { count : 1 };
    }

    delta() {
        this.setState({
            count : this.state.count++
        });
    }

    render() {
        return (
            <div>
              <h1>{this.state.count}</h1>
              <button onClick={this.delta.bind(this)}>+</button>
            </div>
            );
    }
}

Just be careful, beside the syntax difference in the class implementation, there is a difference in the event handler binding.

In the ES5 version, it's

              <button onClick={this.delta}>+</button>

In the ES6 version, it's:

              <button onClick={this.delta.bind(this)}>+</button>

try this MDICHILD function

public void mdiChild(Form mdiParent, Form mdiChild)
{
    foreach (Form frm in mdiParent.MdiChildren)
    {
        // check if name equals
        if (frm.Name == mdiChild.Name)
        {
            //close if found

            frm.Close();

            return;
        }
    }

    mdiChild.MdiParent = mdiParent;

    mdiChild.Show();

    mdiChild.BringToFront();
}

Are you explicitly setting the values as blank? For example:

<input type="text" name="textfield" value="">

That should stop browsers putting data in where it shouldn't. Alternatively, you can add the autocomplete attribute to the form tag:

<form autocomplete="off" ...></form>

A lot of the answers here do not work for (string)"0.00".

Try this:

if (isset($_POST['num1']) && (float)$_POST['num1'] != 0) {
  ...
}

Or even more strict:

if (isset($_POST['num1']) && is_numeric($_POST['num1']) && (float)$_POST['num1'] != 0) {
  ...
}

The argument you passed "Hello" is on the constant data area. Unless you've allocated enough memory to char * string, it's overrunning to other variables.

char buffer[1024];
memset(buffer, 0, sizeof(buffer));
strncpy(buffer, "Hello", sizeof(buffer));
StringPadRight(buffer, 10, "0");

Edit: Corrected from stack to constant data area.

public Image Base64ToImage(string base64String)
{
   // Convert Base64 String to byte[]
    byte[] imageBytes = Convert.FromBase64String(base64String);
    MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);

    // Convert byte[] to Image
    ms.Write(imageBytes, 0, imageBytes.Length);
    Image image = Image.FromStream(ms, true);

    return image;
}
