Once you pass the assembly instance back to the caller domain, the caller domain will try to load it! This is why you get the exception. This happens in your last line of code:

domain.Load(AssemblyName.GetAssemblyName(path));

Thus, whatever you want to do with the assembly, should be done in a proxy class - a class which inherit MarshalByRefObject.

Take in count that the caller domain and the new created domain should both have access to the proxy class assembly. If your issue is not too complicated, consider leaving the ApplicationBase folder unchanged, so it will be same as the caller domain folder (the new domain will only load Assemblies it needs).

In simple code:

public void DoStuffInOtherDomain()
{
    const string assemblyPath = @"[AsmPath]";
    var newDomain = AppDomain.CreateDomain("newDomain");
    var asmLoaderProxy = (ProxyDomain)newDomain.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, typeof(ProxyDomain).FullName);

    asmLoaderProxy.GetAssembly(assemblyPath);
}

class ProxyDomain : MarshalByRefObject
{
    public void GetAssembly(string AssemblyPath)
    {
        try
        {
            Assembly.LoadFrom(AssemblyPath);
            //If you want to do anything further to that assembly, you need to do it here.
        }
        catch (Exception ex)
        {
            throw new InvalidOperationException(ex.Message, ex);
        }
    }
}

If you do need to load the assemblies from a folder which is different than you current app domain folder, create the new app domain with specific dlls search path folder.

For example, the app domain creation line from the above code should be replaced with:

var dllsSearchPath = @"[dlls search path for new app domain]";
AppDomain newDomain = AppDomain.CreateDomain("newDomain", new Evidence(), dllsSearchPath, "", true);

This way, all the dlls will automaically be resolved from dllsSearchPath.

To have the query always handy, without changing code add this to your DbContext and check it on the output window in visual studio.

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        Database.Log = (query)=> Debug.Write(query);
    }

Similar to @Matt Nibecker answer, but with this you do not have to add it in your current code, every time you need the query.

I think a simple and clean solution is to use pattern validation.

The following pattern will allow a string that starts with white spaces and will not allow a string containing only white spaces:

/^(\s+\S+\s*)*(?!\s).*$/

It can be set when adding the validators for the corresponding control of the form group:

const form = this.formBuilder.group({
            name: ['', [
                Validators.required,
                Validators.pattern(/^(\s+\S+\s*)*(?!\s).*$/)
            ]]
        });

Sometimes autoplay is needed. Someone once pointed out that the famous Les Paul Google Doodle (2011) required autoplay, even though the sound didn't play until you moused over the guitar strings. If it's done with class and great design it can be beautiful (especially movie websites with immersive design)

There are actually two accepted best practices:

1. Make the zero value of your struct a sensible default. (While this looks strange to most people coming from "traditional" oop it often works and is really convenient).
2. Provide a function func New() YourTyp or if you have several such types in your package functions func NewYourType1() YourType1 and so on.

Document if a zero value of your type is usable or not (in which case it has to be set up by one of the New... functions. (For the "traditionalist" oops: Someone who does not read the documentation won't be able to use your types properly, even if he cannot create objects in undefined states.)

Please try this

SELECT *
FROM   [Village]
WHERE  CONVERT(VARCHAR, CastleType) = 'foo'

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

I think this is the clearest way:

require 'open-uri'

File.write 'image.png', open('http://example.com/image.png').read

This is the job for style property:

document.getElementById("remember").style.visibility = "visible";

#multiplying each element in the list and adding it into an empty list
original = [1, 2, 3]
results = []
for num in original:
    results.append(num*2)# multiply each iterative number by 2 and add it to the empty list.

print(results)

I had the same problem in my Application.

System.web.http.webhost not found.

You just need to copy the system.web.http.webhost file from your main project which you run in Visual Studio and paste it into your published project bin directory.

After this it may show the same error but the directory name is changed it may be system.web.http. Follow same procedure as above. It will work after all the files are uploaded. This due to the nuget package in Visual Studio they download from the internet but on server it not able to download it.

You can find this file in your project bin directory.

I think, that you have to declare the associated sheet!

Try something like this

objsheet(1).Cells[i,j].Value;

React Router v5 - React 16.8+ with Hooks (updated 09/23/2020)

If you're leveraging React Hooks, you can take advantage of the useHistory API that comes from React Router v5.

import React, {useCallback} from 'react';
import {useHistory} from 'react-router-dom';

export default function StackOverflowExample() {
  const history = useHistory();
  const handleOnClick = useCallback(() => history.push('/sample'), [history]);

  return (
    <button type="button" onClick={handleOnClick}>
      Go home
    </button>
  );
}

Another way to write the click handler if you don't want to use useCallback

const handleOnClick = () => history.push('/sample');

React Router v4 - Redirect Component

The v4 recommended way is to allow your render method to catch a redirect. Use state or props to determine if the redirect component needs to be shown (which then trigger's a redirect).

import { Redirect } from 'react-router';

// ... your class implementation

handleOnClick = () => {
  // some action...
  // then redirect
  this.setState({redirect: true});
}

render() {
  if (this.state.redirect) {
    return <Redirect push to="/sample" />;
  }

  return <button onClick={this.handleOnClick} type="button">Button</button>;
}

Reference: https://reacttraining.com/react-router/web/api/Redirect

React Router v4 - Reference Router Context

You can also take advantage of Router's context that's exposed to the React component.

static contextTypes = {
  router: PropTypes.shape({
    history: PropTypes.shape({
      push: PropTypes.func.isRequired,
      replace: PropTypes.func.isRequired
    }).isRequired,
    staticContext: PropTypes.object
  }).isRequired
};

handleOnClick = () => {
  this.context.router.push('/sample');
}

This is how <Redirect /> works under the hood.

Reference: https://github.com/ReactTraining/react-router/blob/master/packages/react-router/modules/Redirect.js#L46,L60

React Router v4 - Externally Mutate History Object

If you still need to do something similar to v2's implementation, you can create a copy of BrowserRouter then expose the history as an exportable constant. Below is a basic example but you can compose it to inject it with customizable props if needed. There are noted caveats with lifecycles, but it should always rerender the Router, just like in v2. This can be useful for redirects after an API request from an action function.

// browser router file...
import createHistory from 'history/createBrowserHistory';
import { Router } from 'react-router';

export const history = createHistory();

export default class BrowserRouter extends Component {
  render() {
    return <Router history={history} children={this.props.children} />
  }
}

// your main file...
import BrowserRouter from './relative/path/to/BrowserRouter';
import { render } from 'react-dom';

render(
  <BrowserRouter>
    <App/>
  </BrowserRouter>
);

// some file... where you don't have React instance references
import { history } from './relative/path/to/BrowserRouter';

history.push('/sample');

Latest BrowserRouter to extend: https://github.com/ReactTraining/react-router/blob/master/packages/react-router-dom/modules/BrowserRouter.js

React Router v2

Push a new state to the browserHistory instance:

import {browserHistory} from 'react-router';
// ...
browserHistory.push('/sample');

Goto Preferences: -> Maven Click 'Add Remote Catalog' File: http://repo1.maven.org/maven2/archetype-catalog.xml Desc: Catalog

Call the program like this:

(cd /c; /a/helloworld)

The parentheses cause a sub-shell to be spawned. This sub-shell then changes its working directory to /c, then executes helloworld from /a. After the program exits, the sub-shell terminates, returning you to your prompt of the parent shell, in the directory you started from.

Error handling: To avoid running the program without having changed the directory, e.g. when having misspelled /c, make the execution of helloworld conditional:

(cd /c && /a/helloworld)

Reducing memory usage: To avoid having the subshell waste memory while hello world executes, call helloworld via exec:

(cd /c && exec /a/helloworld)

You can use Replace function as;

REPLACE ('Your String with cityname here', 'cityname', 'xyz')
--Results
'Your String with xyz here'

If you apply this to a table column where stringColumnName, cityName both are columns of YourTable

SELECT REPLACE(stringColumnName, cityName, '')
FROM YourTable

Or if you want to remove 'cityName' string from out put of a column then

SELECT REPLACE(stringColumnName, 'cityName', '')
FROM yourTable

EDIT: Since you have given more details now, REPLACE function is not the best method to sort your problem. Following is another way of doing it. Also @MartinSmith has given a good answer. Now you have the choice to select again.

SELECT RIGHT (O.Ort, LEN(O.Ort) - LEN(C.CityName)-1) As WithoutCityName
FROM   tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004'

Simply:

 try {
    const cmd = 'git rev-parse --is-inside-work-tree';
    execSync(cmd).toString();
 } catch (error) {
    console.log(`Status Code: ${error.status} with '${error.message}'`;
 }

Ref: https://stackoverflow.com/a/43077917/104085

// nodejs
var execSync = require('child_process').execSync;

// typescript
const { execSync } = require("child_process");

 try {
    const cmd = 'git rev-parse --is-inside-work-tree';
    execSync(cmd).toString();
 } catch (error) {
    error.status;  // 0 : successful exit, but here in exception it has to be greater than 0
    error.message; // Holds the message you typically want.
    error.stderr;  // Holds the stderr output. Use `.toString()`.
    error.stdout;  // Holds the stdout output. Use `.toString()`.
 }

When command runs successful:

If you have a string of XML, rather than a doc ready for use, you can do it this way:

var xmlString = "<xml>...</xml>"; // Your original XML string that needs indenting.
xmlString = this.PrettifyXml(xmlString);

private string PrettifyXml(string xmlString)
{
    var prettyXmlString = new StringBuilder();

    var xmlDoc = new XmlDocument();
    xmlDoc.LoadXml(xmlString);

    var xmlSettings = new XmlWriterSettings()
    {
        Indent = true,
        IndentChars = " ",
        NewLineChars = "\r\n",
        NewLineHandling = NewLineHandling.Replace
    };

    using (XmlWriter writer = XmlWriter.Create(prettyXmlString, xmlSettings))
    {
        xmlDoc.Save(writer);
    }

    return prettyXmlString.ToString();
}

You don't declare anything in Python. You just use it. I recommend you start out with something like http://diveintopython.net.

You want to add the IN() clause to your WHERE

SELECT * 
FROM `Buses` 
WHERE `BusID` IN (Id1, ID2, ID3,.... put your ids here)

If you have a list of Ids stored in a table you can also do this:

SELECT * 
FROM `Buses` 
WHERE `BusID` IN (SELECT Id FROM table)

I found following example.

https://web.archive.org/web/20120203022122/http://www.silassewell.com/blog/2010/06/03/node-js-https-ssl-server-example/

This works for node v0.1.94 - v0.3.1. server.setSecure() is removed in newer versions of node.

Directly from that source:

const crypto = require('crypto'),
  fs = require("fs"),
  http = require("http");

var privateKey = fs.readFileSync('privatekey.pem').toString();
var certificate = fs.readFileSync('certificate.pem').toString();

var credentials = crypto.createCredentials({key: privateKey, cert: certificate});

var handler = function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
};

var server = http.createServer();
server.setSecure(credentials);
server.addListener("request", handler);
server.listen(8000);

df = pd.DataFrame([['p',1,3,2], ['q',4,3,2], ['r',4,0,9]], columns=['ID','A','B','C'])
my_dict = {k:list(v) for k,v in zip(df['ID'], df.drop(columns='ID').values)}
print(my_dict)

with output

{'p': [1, 3, 2], 'q': [4, 3, 2], 'r': [4, 0, 9]}

I ran into this issue as well. My fix was to create a child schema. See below for an example for your models.

---- Person model

const mongoose = require('mongoose');
const SingleFriend = require('./SingleFriend');
const Schema   = mongoose.Schema;

const productSchema = new Schema({
  friends    : [SingleFriend.schema]
});

module.exports = mongoose.model('Person', personSchema);

***Important: SingleFriend.schema -> make sure to use lowercase for schema

--- Child schema

const mongoose = require('mongoose');
const Schema   = mongoose.Schema;

const SingleFriendSchema = new Schema({
  Name: String
});

module.exports = mongoose.model('SingleFriend', SingleFriendSchema);

We can export a jar file for Android library project without resource files by Android studio. It is also requirement what I met recently.

1. Config your build.gradle file

    // Task to delete old jar

    task clearJar(type: Delete){
       delete 'release/lunademo.jar'
    }

    // task to export contents as jar
    task makeJar(type: Copy) {
       from ('build/intermediates/bundles/release/')
       into ('build/libs/')
       include ('classes.jar')
       rename('classes.jar', 'lunademo.jar')
    }
    makeJar.dependsOn(clearJar, build)

2. Run gradlew makeJar under your project root

You will see your libs under dir as build/libs/ if you are luckily.

============================================================

If you met issue as "Socket timeout exception" on command line as below,

You can follow this steps to open Gradle window in the right part and click "makeJar" on Android studio like this,

Then go to build/libs dir, you will see your jar file.

Hope that it is helpful for u.

Good Luck @.@

If you need to call plot multiply times, you can also use the "label" argument:

ax = df1.plot(label='df1', y='y_var')
ax = df2.plot(label='df2', y='y_var')

While this is not the case in the OP question, this can be helpful if the DataFrame is in long format and you use groupby before plotting.

If we have a greater number of such svg images we can also take the help of font-files.
Sites like https://glyphter.com/ can get us a font file from our svgs.

E.g.

@font-face {
    font-family: 'iconFont';
    src: url('iconFont.eot');
}
#target{
    color: white;
    font-size:96px;
    font-family:iconFont;
}

I just got his working using the ViewSwitcher in a ListItem.

list_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >

<ViewSwitcher
    android:id="@+id/list_switcher"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"

        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:clickable="false"
        android:gravity="center"
        >

    <Button
        android:id="@+id/b_edit_in_list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Edit"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"

         />
    <Button
        android:id="@+id/b_delete_in_list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:paddingRight="20dp"
        android:background="@android:color/holo_red_dark"
        />
    </LinearLayout>
</ViewSwitcher>

In the ListAdapter: Implement OnclickListeners for the Edit and Delete button in the getView() method. The catch here is to get the position of the ListItem clicked inside the onClick methods. setTag() and getTag() methods are used for this.

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    final ViewHolder viewHolder;
    if (convertView == null) {
        viewHolder = new ViewHolder();
        convertView = mInflater.inflate(R.layout.list_item, null);
        viewHolder.viewSwitcher=(ViewSwitcher)convertView.findViewById(R.id.list_switcher);
        viewHolder.itemName = (TextView) convertView
                .findViewById(R.id.tv_item_name);
        viewHolder.deleteitem=(Button)convertView.findViewById(R.id.b_delete_in_list);
        viewHolder.deleteItem.setTag(position);
        viewHolder.editItem=(Button)convertView.findViewById(R.id.b_edit_in_list);
        viewHolder.editItem.setTag(position);
        viewHolder.deleteItem.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                fragment.deleteItemList((Integer)v.getTag());
            }
        });

        viewHolder.editItem.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                fragment.editItemList(position);
            }
        });
        convertView.setTag(viewHolder);
} else {
        viewHolder = (ViewHolder) convertView.getTag();
    }

    viewHolder.itemName.setText(itemlist[position]);
return convertView;  
}

In the Fragment, Add a Gesture Listener to detect the Fling Gesture:

public class MyGestureListener extends SimpleOnGestureListener {
    private ListView list;

    public MyGestureListener(ListView list) {
        this.list = list;
    }

    // CONDITIONS ARE TYPICALLY VELOCITY OR DISTANCE

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        // if (INSERT_CONDITIONS_HERE)

        ltor=(e2.getX()-e1.getX()>DELTA_X);
        if (showDeleteButton(e1))
        {
            return true;
        }
        return super.onFling(e1, e2, velocityX, velocityY);
    }

    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2,
            float distanceX, float distanceY) {
        // TODO Auto-generated method stub
        return super.onScroll(e1, e2, distanceX, distanceY);
    }

    private boolean showDeleteButton(MotionEvent e1) {
        int pos = list.pointToPosition((int) e1.getX(), (int) e1.getY());
        return showDeleteButton(pos);
    }

    private boolean showDeleteButton(int pos) {

        View child = list.getChildAt(pos);
        if (child != null) {
            Button delete = (Button) child
                    .findViewById(R.id.b_edit_in_list);
            ViewSwitcher viewSwitcher = (ViewSwitcher) child
                    .findViewById(R.id.host_list_switcher);
            TextView hostName = (TextView) child
                    .findViewById(R.id.tv_host_name);
            if (delete != null) {
                    viewSwitcher.setInAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.slide_in_left));
                    viewSwitcher.setOutAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.slide_out_right));
                }

                viewSwitcher.showNext();
                // frameLayout.setVisibility(View.VISIBLE);
            }
            return true;
        }
        return false;
    }
}

In the onCreateView method of the Fragment,

GestureDetector gestureDetector = new GestureDetector(getActivity(),
            new MyGestureListener(hostList));
    hostList.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            if (gestureDetector.onTouchEvent(event)) {
                return true;
            } else {
                return false;
            }

        }
    });

This worked for me. Should refine it more.

Have you tried what is on the sample. I am new to this but here is the command: puppet --test --trace --debug. I hope this helps.

The best option is to use the original LESS version of bootstrap (get it from github).

Open variables.less and look for // Media queries breakpoints

Find this code and change the breakpoint value:

// Large screen / wide desktop
@screen-lg:                  1200px; // change this
@screen-lg-desktop:          @screen-lg;

Change it to 9999px for example, and this will prevent the breakpoint to be reached, so your site will always load the previous media query which has 940px container

The defaultdict solution is better. But for completeness you could also check and create empty list before the append. Add the + lines:

+ if not u in self.adj.keys():
+     self.adj[u] = []
  self.adj[u].append(edge)
.
.

np.where(pd.isnull(df)) returns the row and column indices where the value is NaN:

In [152]: import numpy as np
In [153]: import pandas as pd
In [154]: np.where(pd.isnull(df))
Out[154]: (array([2, 5, 6, 6, 7, 7]), array([7, 7, 6, 7, 6, 7]))

In [155]: df.iloc[2,7]
Out[155]: nan

In [160]: [df.iloc[i,j] for i,j in zip(*np.where(pd.isnull(df)))]
Out[160]: [nan, nan, nan, nan, nan, nan]

Finding values which are empty strings could be done with applymap:

In [182]: np.where(df.applymap(lambda x: x == ''))
Out[182]: (array([5]), array([7]))

Note that using applymap requires calling a Python function once for each cell of the DataFrame. That could be slow for a large DataFrame, so it would be better if you could arrange for all the blank cells to contain NaN instead so you could use pd.isnull.

From git stash --help

Recovering stashes that were cleared/dropped erroneously
   If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
   following incantation to get a list of stashes that are still in your repository, but not reachable any more:

       git fsck --unreachable |
       grep commit | cut -d\  -f3 |
       xargs git log --merges --no-walk --grep=WIP

This helped me better than the accepted answer with the same scenario.

There are some problems when logical vector contains NA values.
See for example:

z <- c(TRUE, FALSE, NA)
sum(z) # gives you NA
table(z)["TRUE"] # gives you 1
length(z[z == TRUE]) # f3lix answer, gives you 2 (because NA indexing returns values)

So I think the safest is to use na.rm = TRUE:

sum(z, na.rm = TRUE) # best way to count TRUE values

(which gives 1). I think that table solution is less efficient (look at the code of table function).

Also, you should be careful with the "table" solution, in case there are no TRUE values in the logical vector. Suppose z <- c(NA, FALSE, NA) or simply z <- c(FALSE, FALSE), then table(z)["TRUE"] gives you NA for both cases.

I had this error:

OK, Firefox 7 implemented text-overflow: ellipsis as well as text-overflow: "string". Final release is planned for 2011-09-27.

Use a DecimalFormat object with a format string of "0.#".

Try this:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Confirm");
builder.setMessage("Are you sure?");

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        // Do nothing but close the dialog

        dialog.dismiss();
    }
});

builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        // Do nothing
        dialog.dismiss();
    }
});

AlertDialog alert = builder.create();
alert.show();

In my Startup.cs (Core 2.2, Automapper 8.1.1)

services.AddAutoMapper(new Type[] { typeof(DAL.MapperProfile) });            

In my data access project

namespace DAL
{
    public class MapperProfile : Profile
    {
        // place holder for AddAutoMapper (to bring in the DAL assembly)
    }
}

In my model definition

namespace DAL.Models
{
    public class PositionProfile : Profile
    {
        public PositionProfile()
        {
            CreateMap<Position, PositionDto_v1>();
        }
    }

    public class Position
    {
        ...
    }

If you would like to check in PHP , then you should do something like :

$query_s =mysql_query("SELECT YOURROWNAME from `YOURTABLENAME` where name = $name");
$ertom=mysql_fetch_array($query_s);
if ('' !== $ertom['YOURROWNAME']) {
  //do your action
  echo "It was filled";
} else { 
  echo "it was empty!";
}

You can run OpenSSH on Cygwin, and even install it as a Windows service.

I once used it this way to easily add backups of a Unix system - it would rsync a bunch of files onto the Windows server, and the Windows server had full tape backups.

First, fetch the latest commits from the remote repo. This will not affect your local branch.

git fetch origin

Then checkout the remote tracking branch and do a git log to see the commits

git checkout origin/master
git log

Grab the commit hash of the commit you want to merge up to (or just the first ~5 chars of it) and merge that commit into master

git checkout master
git merge <commit hash>

"From ArrayBuffer to Buffer" could be done this way:

var buffer = Buffer.from( new Uint8Array(ab) );

OK, guys, here's my little test too. I had a similar problem, so I decided to test out 3 situations:

1. One HTML file, one external JS file... does it work at all - can functions communicate via a global var?
2. Two HTML files, one external JS file, one browser, two tabs: will they interfere via the global var?
3. One HTML file, open by 2 browsers, will it work and will they interfere?

All the results were as expected.

1. It works. Functions f1() and f2() communicate via global var (var is in the external JS file, not in HTML file).
2. They do not interfere. Apparently distinct copies of JS file have been made for each browser tab, each HTML page.
3. All works independently, as expected.

Instead of browsing tutorials, I found it easier to try it out, so I did. My conclusion: whenever you include an external JS file in your HTML page, the contents of the external JS gets "copy/pasted" into your HTML page before the page is rendered. Or into your PHP page if you will. Please correct me if I'm wrong here. Thanx.

My example files follow:

EXTERNAL JS:

var global = 0;

function f1()
{
    alert('fired: f1');
    global = 1;
    alert('global changed to 1');
}

function f2()
{
    alert('fired f2');
    alert('value of global: '+global);
}

Dason K. and I have the pacman package that can do this nicely. The function p_load in the package does this. The first line is just to ensure that pacman is installed.

if (!require("pacman")) install.packages("pacman")
pacman::p_load(package1, package2, package_n)

Summernote converts your uploaded images to a base64 encoded string by default, you can process this string or as other fellows mentioned you can upload images using onImageUpload callback. You can take a look at this gist which I modified a bit to adapt laravel csrf token here. But that did not work for me and I had no time to find out why! Instead, I solved it via a server-side solution based on this blog post. It gets the output of the summernote and then it will upload the images and updates the final markdown HTML.

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

Route::get('/your-route-to-editor', function () {
    return view('your-view');
});

Route::post('/your-route-to-processor', function (Request $request) {

       $this->validate($request, [
           'editordata' => 'required',
       ]);

       $data = $request->input('editordata');

       //loading the html data from the summernote editor and select the img tags from it
       $dom = new \DomDocument();
       $dom->loadHtml($data, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);    
       $images = $dom->getElementsByTagName('img');
       
       foreach($images as $k => $img){
           //for now src attribute contains image encrypted data in a nonsence string
           $data = $img->getAttribute('src');
           //getting the original file name that is in data-filename attribute of img
           $file_name = $img->getAttribute('data-filename');
           //extracting the original file name and extension
           $arr = explode('.', $file_name);
           $upload_base_directory = 'public/';

           $original_file_name='time()'.$k;
           $original_file_extension='png';

           if (sizeof($arr) ==  2) {
                $original_file_name = $arr[0];
                $original_file_extension = $arr[1];
           }
           else
           {
                //the file name contains extra . in itself
                $original_file_name = implode("_",array_slice($arr,0,sizeof($arr)-1));
                $original_file_extension = $arr[sizeof($arr)-1];
           }

           list($type, $data) = explode(';', $data);
           list(, $data)      = explode(',', $data);

           $data = base64_decode($data);

           $path = $upload_base_directory.$original_file_name.'.'.$original_file_extension;

           //uploading the image to an actual file on the server and get the url to it to update the src attribute of images
           Storage::put($path, $data);

           $img->removeAttribute('src');       
           //you can remove the data-filename attribute here too if you want.
           $img->setAttribute('src', Storage::url($path));
           // data base stuff here :
           //saving the attachments path in an array
       }

       //updating the summernote WYSIWYG markdown output.
       $data = $dom->saveHTML();

       // data base stuff here :
       // save the post along with it attachments array
       return view('your-preview-page')->with(['data'=>$data]);

});

To enable the same edmx to access multiple databases and database providers and vise versa I use the following technique:

1) Define a ConnectionManager:

public static class ConnectionManager
{
    public static string GetConnectionString(string modelName)
    {
        var resourceAssembly = Assembly.GetCallingAssembly();

        var resources = resourceAssembly.GetManifestResourceNames();

        if (!resources.Contains(modelName + ".csdl")
            || !resources.Contains(modelName + ".ssdl")
            || !resources.Contains(modelName + ".msl"))
        {
            throw new ApplicationException(
                    "Could not find connection resources required by assembly: "
                    + System.Reflection.Assembly.GetCallingAssembly().FullName);
        }

        var provider = System.Configuration.ConfigurationManager.AppSettings.Get(
                        "MyModelUnitOfWorkProvider");

        var providerConnectionString = System.Configuration.ConfigurationManager.AppSettings.Get(
                        "MyModelUnitOfWorkConnectionString");

        string ssdlText;

        using (var ssdlInput = resourceAssembly.GetManifestResourceStream(modelName + ".ssdl"))
        {
            using (var textReader = new StreamReader(ssdlInput))
            {
                ssdlText = textReader.ReadToEnd();
            }
        }

        var token = "Provider=\"";
        var start = ssdlText.IndexOf(token);
        var end = ssdlText.IndexOf('"', start + token.Length);
        var oldProvider = ssdlText.Substring(start, end + 1 - start);

        ssdlText = ssdlText.Replace(oldProvider, "Provider=\"" + provider + "\"");

        var tempDir = Environment.GetEnvironmentVariable("TEMP") + '\\' + resourceAssembly.GetName().Name;
        Directory.CreateDirectory(tempDir);

        var ssdlOutputPath = tempDir + '\\' + Guid.NewGuid() + ".ssdl";

        using (var outputFile = new FileStream(ssdlOutputPath, FileMode.Create))
        {
            using (var outputStream = new StreamWriter(outputFile))
            {
                outputStream.Write(ssdlText);
            }
        }

        var eBuilder = new EntityConnectionStringBuilder
        {
            Provider = provider,

            Metadata = "res://*/" + modelName + ".csdl"
                        + "|" + ssdlOutputPath
                        + "|res://*/" + modelName + ".msl",

            ProviderConnectionString = providerConnectionString
        };

        return eBuilder.ToString();
    }
}

2) Modify the T4 that creates your ObjectContext so that it will use the ConnectionManager:

public partial class MyModelUnitOfWork : ObjectContext
{
    public const string ContainerName = "MyModelUnitOfWork";
    public static readonly string ConnectionString
        = ConnectionManager.GetConnectionString("MyModel");

3) Add the following lines to App.Config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="MyModelUnitOfWork" connectionString=... />
  </connectionStrings>
  <appSettings>
    <add key="MyModelUnitOfWorkConnectionString" value="data source=MyPc\SqlExpress;initial catalog=MyDB;integrated security=True;multipleactiveresultsets=True" />
    <add key="MyModelUnitOfWorkProvider" value="System.Data.SqlClient" />
  </appSettings>
</configuration>

The ConnectionManager will replace the ConnectionString and Provider to what ever is in the App.Config.

You can use the same ConnectionManager for all ObjectContexts (so they all read the same settings from App.Config), or edit the T4 so it creates one ConnectionManager for each (in its own namespace), so that each reads separate settings.

Firstly, write an unzip utility using vbscript to trigger the native unzip functionality in Windows. Then pipe out the script from within your batch file and then call it. Then it's as good as stand alone. I've done it in the past for numerous tasks. This way it does not require need of third party applications, just the one batch file that does everything.

I put an example on my blog on how to unzip a file using a batch file:

' j_unzip.vbs
'
' UnZip a file script
'
' By Justin Godden 2010
'
' It's a mess, I know!!!
'

' Dim ArgObj, var1, var2
Set ArgObj = WScript.Arguments

If (Wscript.Arguments.Count > 0) Then
 var1 = ArgObj(0)
Else
 var1 = ""
End if

If var1 = "" then
 strFileZIP = "example.zip"
Else
 strFileZIP = var1
End if

'The location of the zip file.
REM Set WshShell = CreateObject("Wscript.Shell")
REM CurDir = WshShell.ExpandEnvironmentStrings("%%cd%%")
Dim sCurPath
sCurPath = CreateObject("Scripting.FileSystemObject").GetAbsolutePathName(".")
strZipFile = sCurPath & "\" & strFileZIP
'The folder the contents should be extracted to.
outFolder = sCurPath & "\"

 WScript.Echo ( "Extracting file " & strFileZIP)

Set objShell = CreateObject( "Shell.Application" )
Set objSource = objShell.NameSpace(strZipFile).Items()
Set objTarget = objShell.NameSpace(outFolder)
intOptions = 256
objTarget.CopyHere objSource, intOptions

 WScript.Echo ( "Extracted." )

' This bit is for testing purposes
REM Dim MyVar
REM MyVar = MsgBox ( strZipFile, 65, "MsgBox Example"

Use it like this:

cscript //B j_unzip.vbs zip_file_name_goes_here.zip

I thought I could do that, but quite disappointed: it doesn't work, but I think it still worths sharing.

Maybe someone can correct:

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;

interface SomeContainer<E> {
    E createContents();
}

public class Main {

    @SuppressWarnings("unchecked")
    public static <E> SomeContainer<E> createSomeContainer() {
        return (SomeContainer<E>) Proxy.newProxyInstance(Main.class.getClassLoader(),
                new Class[]{ SomeContainer.class }, new InvocationHandler() {
            @Override
            public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
                Class<?> returnType = method.getReturnType();
                return returnType.newInstance();
            }
        });
    }

    public static void main(String[] args) {
        SomeContainer<String> container = createSomeContainer();

    [*] System.out.println("String created: [" +container.createContents()+"]");

    }
}

It produces:

Also, you should remember that if you run your web server at non-standard port you need to include port number at base href too:

<base href="//localhost:1234" />  // from base url
<base href="../" />  // for one step above

Setting the slice to nil is the best way to clear a slice. nil slices in go are perfectly well behaved and setting the slice to nil will release the underlying memory to the garbage collector.

See playground

package main

import (
    "fmt"
)

func dump(letters []string) {
    fmt.Println("letters = ", letters)
    fmt.Println(cap(letters))
    fmt.Println(len(letters))
    for i := range letters {
        fmt.Println(i, letters[i])
    }
}

func main() {
    letters := []string{"a", "b", "c", "d"}
    dump(letters)
    // clear the slice
    letters = nil
    dump(letters)
    // add stuff back to it
    letters = append(letters, "e")
    dump(letters)
}

Prints

letters =  [a b c d]
4
4
0 a
1 b
2 c
3 d
letters =  []
0
0
letters =  [e]
1
1
0 e

Note that slices can easily be aliased so that two slices point to the same underlying memory. The setting to nil will remove that aliasing.

This method changes the capacity to zero though.

Add ScalarsConverterFactory.create() method and pass hard code

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

With Oracle's new SQLcl there is a cd command now and accompanying pwd. SQLcl can be downloaded here: http://www.oracle.com/technetwork/developer-tools/sqlcl/overview/index.html

You can use sets. Just to be clear, I am explaining what is the difference between a list and a set. sets are unordered collection of unique elements.Lists are ordered collection of elements. So,

    unicode_list=[u'nowplaying', u'PBS', u'PBS', u'nowplaying', u'job',u'debate', u'thenandnow']
    list_unique=list(set(unicode_list))
    print list_unique
[u'nowplaying', u'job', u'debate', u'PBS', u'thenandnow']

But: Do not use list/set in naming the variables. It will cause error: EX: Instead of use list instead of unicode_list in the above one.

list=[u'nowplaying', u'PBS', u'PBS', u'nowplaying', u'job',u'debate', u'thenandnow']
        list_unique=list(set(list))
        print list_unique
    list_unique=list(set(list))
TypeError: 'list' object is not callable

Button button= (Button) findViewById(R.id.standingsButton);
button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        startActivity(new Intent(MainActivity.this,StandingsActivity.class));
    }
});

This code is not in any method. If you want to use it, it must be within a method like OnCreate()

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button button= (Button) findViewById(R.id.standingsButton);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(new Intent(MainActivity.this,StandingsActivity.class));
        }
    });
}

More cleaner way using LINQ

var lines = dictionary.Select(kvp => kvp.Key + ": " + kvp.Value.ToString());
textBox3.Text = string.Join(Environment.NewLine, lines);

AutoHotKey is perfect for this kind of tasks (keyboard automation / remapping)

Script to send "A" 100 times:

Send {A 100}

That's all

EDIT: to send the keys to an specific application:

WinActivate Word
Send {A 100}

Use rowspan if you want to extend cells down and colspan to extend across.

To calculate power(2, n), simply use:

let result = 2 << (n-1)

You can use http://logging.apache.org/ library and use a database appender to collect all your log info together.

Since nobody so far felt fit to point out why what you're trying doesn't work:

1. NA == NA doesn't return TRUE, it returns NA (since comparing to undefined values should yield an undefined result).
2. You're trying to call apply on an atomic vector. You can't use apply to loop over the elements in a column.
3. Your subscripts are off - you're trying to give two indices into a$x, which is just the column (an atomic vector).

I'd fix up 3. to get to a$x[is.na(a$x)] <- 0

From reading the source code, if a java.sql.Date does actually have time information, calling getTime() will return a value that includes the time information.

If that is not working, then the information is not in the java.sql.Date object. I expect that the JDBC drivers or the database is (in effect) zeroing the time component ... or the information wasn't there in the first place.

I think you should be using java.sql.Timestamp and the corresponding resultset methods, and the corresponding SQL type.

Keep away from QuickSort - its very inefficient for pre-sorted data. Insertion sort handles almost sorted data well by moving as few values as possible.

It looks a little odd, even silly, but this is working for me:

input.val(lastQuery);
input.focus().val(input.val());

Now, I'm not certain I've replicated your setup. I'm assuming input is an <input> element.

By re-setting the value (to itself) I think the cursor is getting put at the end of the input. Tested in Firefox 3 and MSIE7.

You can use Environment.Exit(0) and Application.Exit.

Environment.Exit(): terminates this process and gives the underlying operating system the specified exit code.

Both of these should work:

$("#captureImage").prop('checked', false);

AND/OR

$("#captureImage").removeAttr('checked');

... you can try both together.

you can get the nodejs configuration from http://nodejs.org/
The important thing you need to keep in your mind is about its configuration in file app.js which consists of port number host and other settings these are settings working for me

backendSettings = {
"scheme":"https / http ",
"host":"Your website url",
"port":49165, //port number 
'sslKeyPath': 'Path for key',
'sslCertPath': 'path for SSL certificate',
'sslCAPath': '',
"resource":"/socket.io",
"baseAuthPath": '/nodejs/',
"publishUrl":"publish",
"serviceKey":"",
"backend":{
"port":443,
"scheme": 'https / http', //whatever is your website scheme
"host":"host name",
"messagePath":"/nodejs/message/"},
"clientsCanWriteToChannels":false,
"clientsCanWriteToClients":false,
"extensions":"",
"debug":false,
"addUserToChannelUrl": 'user/channel/add/:channel/:uid',
"publishMessageToContentChannelUrl": 'content/token/message',
"transports":["websocket",
"flashsocket",
"htmlfile",
"xhr-polling",
"jsonp-polling"],
"jsMinification":true,
"jsEtag":true,
"logLevel":1};

In this if you are getting "Error: listen EADDRINUSE" then please change the port number i.e, here I am using "49165" so you can use other port such as 49170 or some other port. For this you can refer to the following article
http://www.a2hosting.com/kb/installable-applications/manual-installations/installing-node-js-on-shared-hosting-accounts

The 60 you're passing is just the initial capacity for internal storage. It's a hint on how big you think it might be, yet of course it's not limited by that. If you need to preset values you'll have to set them yourself, e.g.:

for (int i = 0; i < 60; i++) {
    list.add(0);
}

Did you already check your proxys here?

git config --global --list

or

git config --local --list

Terminate the Timer once after awake at a specific time in milliseconds.

Timer t = new Timer();
t.schedule(new TimerTask() {
            @Override
             public void run() {
             System.out.println(" Run spcific task at given time.");
             t.cancel();
             }
 }, 10000);

The alert() function can't output an object in a read-friendly manner. Try using console.log(object) instead, and fire up your browser's console to debug.

I solved this question by unInstalled ndk, becasuse I dont't need it

You can use boost::optional (or std::optional for newer versions), which was developed in particular for decision of your problem:

boost::optional<int> y[50];
....
geoGraph.y[x] = nums[x];
....
const size_t size_y = sizeof(y)/sizeof(y[0]); //!!!! correct size of y!!!!
for(int i=0; i<size_y;i++){
   if(y[i]) { //check for null
      p[i].SetPoint(Recto.Height()-x,*y[i]);
      ....
   }
}

P.S. Do not use C-type array -> use std::array or std::vector:

std::array<int, 50> y;   //not int y[50] !!!

force it with -l

    sudo umount -l ${HOME}/mount_dir

So you want the next multiple of 6, is that it?

You can divide your number by 6, then ceil it, and multiply it again:

$answer = ceil($foo / 6) * 6;

If you don't want to install xDebug or other extensions and just want to run a PHP file without debugging, you can accomplish this using build tasks.

Using Build Tasks

First open the command palette (Ctrl+Shift+P in Windows, ?+Shift+P in Mac), and select "Tasks:Open User Tasks". Now copy my configuration below into your tasks.json file. This creates user-level tasks which can be used any time and in any workspace.

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Start Server",
            "type": "shell",
            "command": "php -S localhost:8080 -t ${fileDirname}",
            "isBackground": true,
            "group": "build",
            "problemMatcher": []
        },
        {
            "label": "Run In Browser",
            "type": "shell",
            "command": "open http://localhost:8080/${fileBasename}",
            "windows": {
                "command": "explorer 'http://localhost:8080/${fileBasename}'"
            },
            "group": "build",
            "problemMatcher": []
        }
        {
            "label": "Run In Terminal",
            "type": "shell",
            "command": "php ${file}",
            "group": "none",
            "problemMatcher": []
        }
    ]
}

If you want to run your php file in the terminal, open the command palette and select "Tasks: Run Task" followed by "Run In Terminal".

If you want to run your code on a webserver which serves a response to a web browser, open the command palette and select "Tasks: Run Task" followed by "Start Server" to run PHP's built-in server, then "Run In Browser" to run the currently open file from your browser.

Note that if you already have a webserver running, you can remove the Start Server task and update the localhost:8080 part to point to whatever URL you are using.

Using PHP Debug

Note: This section was in my original answer. I originally thought that it works without PHP Debug but it looks like PHP Debug actually exposes the php type in the launch configuration. There is no reason to use it over the build task method described above. I'm keeping it here in case it is useful.

Copy the following configuration into your user settings:

{
    "launch": {
        "version": "0.2.0",
        "configurations": [
            {
            "type": "php",
            "request": "launch",
            "name": "Run using PHP executable",
            "program": "${file}",
            "runtimeExecutable": "/usr/bin/php"
            },
        ]
    },
    // all your other user settings...
}

This creates a global launch configuration that you can use on any PHP file. Note the runtimeExecutable option. You will need to update this with the path to the PHP executable on your machine. After you copy the configuration above, whenever you have a PHP file open, you can press the F5 key to run the PHP code and have the output displayed in the vscode terminal.

Slight modification of Laurynas' plugin based on Igor's code. This accommodates possible labels associated with the radio buttons being targeted:

(function ($) {
    $.fn.uncheckableRadio = function () {

        return this.each(function () {
            var radio = this;
                $('label[for="' + radio.id + '"]').add(radio).mousedown(function () {
                    $(radio).data('wasChecked', radio.checked);
                });

                $('label[for="' + radio.id + '"]').add(radio).click(function () {
                    if ($(radio).data('wasChecked'))
                        radio.checked = false;
                });
           });
    };
})(jQuery);

A quick Google on that ('kth largest element array') returned this: http://discuss.joelonsoftware.com/default.asp?interview.11.509587.17

"Make one pass through tracking the three largest values so far." 

(it was specifically for 3d largest)

and this answer:

Build a heap/priority queue.  O(n)
Pop top element.  O(log n)
Pop top element.  O(log n)
Pop top element.  O(log n)

Total = O(n) + 3 O(log n) = O(n)

Simple answer

If you are behind a proxy server, please set the proxy for curl. The curl is not able to connect to server so it shows wrong version number. Set proxy by opening subl ~/.curlrc or use any other text editor. Then add the following line to file: proxy= proxyserver:proxyport For e.g. proxy = 10.8.0.1:8080

If you are not behind a proxy, make sure that the curlrc file does not contain the proxy settings.

Here is an example to call your webservice using jQuery.get:

$.get("http://domain.com/webservice.asmx", { name: "John", time: "2pm" },
  function(data){
    alert("Data Loaded: " + data);
  });

In the example above, we call "webservice.asmx", passing two parameters: name and time. Then, getting the service output in the call back function.

<a onclick="yourfunction()">

this will work fine . no need to add href="#"

You can install any current version of Anaconda. You can then make a conda environment with your particular needs from the documentation

conda create -n tensorflowproject python=3.5 tensorflow ipython

This command has a specific version for python and when this tensorflowproject environment gets updated it will upgrade to Python 3.5999999999 but never go to 3.6 . Then you switch to your environment using either

source activate tensorflowproject

for linux/mac or

activate tensorflowproject

on windows

You've got the ternary syntax x if x else '' - is that what you're after?

The java.net blog had a class the other day that might have done what you want (but it is down right now so I cannot check).

This code here could probably be modified to do what you want:

http://svn.apache.org/repos/asf/incubator/shindig/trunk/java/common/src/main/java/org/apache/shindig/common/uri/UriBuilder.java

Here is the one I was thinking of from java.net: https://urlencodedquerystring.dev.java.net/

just in case someone finds this searching for errors concerning ActiveStorage:

if you have a controller-action where you want to generate upload-urls etc with the local disc-service (most likely in test environment), you need to include ActiveStorage::SetCurrent in the controller in order to allow blob.service_url_for_direct_upload to work correctly.

px = dp * (dpi / 160)

dp = px * (160 / dpi)

Well, in this case the car variable will be null, so dereferencing it (as you do when you access car.length) will throw a NullPointerException.

In fact, you can't access that variable at all until some value has definitely been assigned to it - otherwise the compiler will complain that "variable car might not have been initialized".

What is it you're trying to do here (it's not clear to me exactly what "solution" you're looking for)?

One line code.

var date = new Date(new Date().getTime());

or

var date = new Date(1584120305684);

You can render a template in your code like so:

from django.template import Context, Template
t = Template('This is your <span>{{ message }}</span>.')

c = Context({'message': 'Your message'})
html = t.render(c)

See the Django docs for further information.

I'm going to offer up a way to return a boolean based on passing an argument of a reflection Kinds to a local type receiver (because I couldn't find anything like this).

First, we declare our anonymous type of type reflect.Value:

type AnonymousType reflect.Value

Then we add a builder for our local type AnonymousType which can take in any potential type (as an interface):

func ToAnonymousType(obj interface{}) AnonymousType {
    return AnonymousType(reflect.ValueOf(obj))
}

Then we add a function for our AnonymousType struct which asserts against a reflect.Kind:

func (a AnonymousType) IsA(typeToAssert reflect.Kind) bool {
    return typeToAssert == reflect.Value(a).Kind()
}

This allows us to call the following:

var f float64 = 3.4

anon := ToAnonymousType(f)

if anon.IsA(reflect.String) {
    fmt.Println("Its A String!")
} else if anon.IsA(reflect.Float32) {
    fmt.Println("Its A Float32!")
} else if anon.IsA(reflect.Float64) {
    fmt.Println("Its A Float64!")
} else {
    fmt.Println("Failed")
}

Can see a longer, working version here:https://play.golang.org/p/EIAp0z62B7

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)

#include <iostream>

int main()
{
    std::cout<<"Hello World!\n";
    return 0;
}

None of the above helped for me.

For posix (Linux, BSD, etc... only need /proc directory to be mounted) it's easier to work with os files in /proc

Works on python 2 and 3 ( The only difference is the Exception tree, therefore the "except Exception", which i dislike but kept to maintain compatibility. Also could've created custom exception.)

#!/usr/bin/env python

import os
import sys


for dirname in os.listdir('/proc'):
    if dirname == 'curproc':
        continue

    try:
        with open('/proc/{}/cmdline'.format(dirname), mode='rb') as fd:
            content = fd.read().decode().split('\x00')
    except Exception:
        continue

    for i in sys.argv[1:]:
        if i in content[0]:
            # dirname is also the number of PID
            print('{0:<12} : {1}'.format(dirname, ' '.join(content)))

Sample Output (it works like pgrep):

phoemur ~/python $ ./pgrep.py bash
1487         : -bash 
1779         : /bin/bash

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

The trunk is the main line of development in a SVN repository.

A branch is a side-line of development created to make larger, experimental or disrupting work without annoying users of the trunk version. Also, branches can be used to create development lines for multiple versions of the same product, like having a place to backport bugfixes into a stable release.

Finally, tags are markers to highlight notable revisions in the history of the repository, usually things like "this was released as 1.0".

See the HTML version of "Version Control with Subversion", especially Chapter 4: Branching and Merging or buy it in paper (e.g. from amazon) for an in-depth discussion of the technical details.

As others (e.g. Peter Neubauer below) the underlying implementation as /tags /branches and /trunk directories is only conventional and not in any way enforced by the tools. Violating these conventions leads to confusion all around, as this breaks habits and expectations of others accessing the repository. Special care must be taken to avoid committing new changes into tags, which should be frozen.

I use TortoiseSVN but no Visual Studio integration. I keep the "Check for modifications" dialog open on the second monitor the whole time, so I can track which files I have touched. But see the "Best SVN Tools" question, for more recommendations.

Don't forget to check whether the string is empty or null. If we forget checking null or empty then we would get NullPointerException or StringIndexOutOfBoundException if a given String is null or empty.

public class StartWithUpperCase{

        public static void main(String[] args){

            String str1 = ""; //StringIndexOfBoundException if 
                              //empty checking not handled
            String str2 = null; //NullPointerException if 
                                //null checking is not handled.
            String str3 = "Starts with upper case";
            String str4 = "starts with lower case";

            System.out.println(startWithUpperCase(str1)); //false
            System.out.println(startWithUpperCase(str2)); //false
            System.out.println(startWithUpperCase(str3)); //true
            System.out.println(startWithUpperCase(str4)); //false



        }

        public static boolean startWithUpperCase(String givenString){

            if(null == givenString || givenString.isEmpty() ) return false;
            else return (Character.isUpperCase( givenString.codePointAt(0) ) );
        }

    }

Both above answers would only return one index if there are multiple rows that take the maximum value. If you want all the rows, there does not seem to have a function. But it is not hard to do. Below is an example for Series; the same can be done for DataFrame:

In [1]: from pandas import Series, DataFrame

In [2]: s=Series([2,4,4,3],index=['a','b','c','d'])

In [3]: s.idxmax()
Out[3]: 'b'

In [4]: s[s==s.max()]
Out[4]: 
b    4
c    4
dtype: int64

A work-around is to use @tvanfosson's answer (the selected answer) and use JQuery (or Javascript) to set the option's value to 0:

$(document).ready(function () {
        $('#DropDownListId option:first').val('0');
    });

Hope this helps.

DisplacedAussie's answer is correct, but usually a shorter method is just to reverse the single axis in question:

plt.scatter(x_arr, y_arr)
ax = plt.gca()
ax.set_ylim(ax.get_ylim()[::-1])

where the gca() function returns the current Axes instance and the [::-1] reverses the list.

remove bootstrap modal background try this one

.modal-backdrop {

}

df.index[df.LastName == 'Smith']

Or

df.query('LastName == "Smith"').index

Will return all row indices where LastName is Smith

• Also Called Query Petition Clause.

• Similar to the Group By Clause

  • break up data into chunks (or partitions)
  • separate by partition bounds
  • function performs within partitions
  • re-initialised when crossing parting boundary

Syntax:
function (...) OVER (PARTITION BY col1 col3,...)

• Functions

  • Familiar functions such as COUNT(), SUM(), MIN(), MAX(), etc
  • New Functions as well (eg ROW_NUMBER(), RATION_TO_REOIRT(), etc.)

There are a couple of things to check:

• In FireBug, see if there are any loading errors that would indicate that your script is badly formatted and the functions do not get registered.
• You can also try typing "proceedToSecond" into the FireBug console to see if the function gets defined
• One thing you may try is removing the space around the @type attribute to the script tag: it should be <script type="text/javascript"> instead of <script type = "text/javascript">

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values

A C++14 version of the answer provided by R. Martinho Fernandes would be:

#include <type_traits>

template <typename E>
constexpr auto to_underlying(E e) noexcept
{
    return static_cast<std::underlying_type_t<E>>(e);
}

As with the previous answer, this will work with any kind of enum and underlying type. I have added the noexcept keyword as it will never throw an exception.

Update
This also appears in Effective Modern C++ by Scott Meyers. See item 10 (it is detailed in the final pages of the item within my copy of the book).

git filter-branch is the major-surgery tool.

git filter-branch --parent-filter true -- @^!

--parent-filter gets the parents on stdin and should print the rewritten parents on stdout; unix true exits successfully and prints nothing, so: no parents. @^! is Git shorthand for "the head commit but not any of its parents". Then delete all the other refs and push at leisure.

In fact you cannot do it easily right now (at the time I am writing this message). I will try to explain why.

First of all, the glibc is no more, it has been subsumed by the eglibc project. And, the Debian distribution switched to eglibc some time ago (see here and there and even on the glibc source package page). So, you should consider installing the eglibc package through this kind of command:

apt-get install libc6-amd64 libc6-dev libc6-dbg

Replace amd64 by the kind of architecture you want (look at the package list here).

Unfortunately, the eglibc package version is only up to 2.13 in unstable and testing. Only the experimental is providing a 2.17 version of this library. So, if you really want to have it in 2.15 or more, you need to install the package from the experimental version (which is not recommended). Here are the steps to achieve as root:

1. Add the following line to the file /etc/apt/sources.list:

   deb http://ftp.debian.org/debian experimental main
   

2. Update your package database:

   apt-get update
   

3. Install the eglibc package:

   apt-get -t experimental install libc6-amd64 libc6-dev libc6-dbg
   

4. Pray...

Well, that's all folks.

I would just like to club all the answers given above and also relate Flush() method with Session.save() so as to give more importance

Hibernate save() can be used to save entity to database. We can invoke this method outside a transaction, that’s why I don’t like this method to save data. If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session.

flush(): Forces the session to flush. It is used to synchronize session data with database.

When you call session.flush(), the statements are executed in database but it will not committed. If you don’t call session.flush() and if you call session.commit() , internally commit() method executes the statement and commits.

So commit()= flush+commit. So session.flush() just executes the statements in database (but not commits) and statements are NOT IN MEMORY anymore. It just forces the session to flush.

Few important points:

We should avoid save outside transaction boundary, otherwise mapped entities will not be saved causing data inconsistency. It’s very normal to forget flushing the session because it doesn’t throw any exception or warnings. By default, Hibernate will flush changes automatically for you: before some query executions when a transaction is committed Allowing to explicitly flush the Session gives finer control that may be required in some circumstances (to get an ID assigned, to control the size of the Session)

You are comparing a jQuery object (jQuery('input:first')) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:

if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)

The inArray method returns -1 if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :

if(jQuery.inArray(el,arr) == -1){
    // the element is not in the array
};

git rm --cached file

should do what you want.

You can read more details at git help rm

I wrote a simple bash script to get around this stupid problem. Pass in the path to a named copy of your provision (downloaded from developer.apple.com) and it will identify the matching GUID-renamed file in your provision library:

#!/bin/bash

if [ -z "$1" ] ; then
  echo -e "\nUsage: $0 <myprovision>\n"
  exit
fi

if [ ! -f "$1" ] ; then
  echo -e "\nFile not found: $1\n"
  exit
fi

provisionpath="$HOME/Library/MobileDevice/Provisioning Profiles"
provisions=$( ls "$provisionpath" )

for i in $provisions ; do
  match=$( diff "$1" "$provisionpath/$i" )
  if [ "$match" = "" ] ; then
    echo -e "\nmatch: $provisionpath/$i\n"
  fi
done

1. del /s /q c:\where ever the file is\*
2. rmdir /s /q c:\where ever the file is\
3. mkdir c:\where ever the file is\

Something like:

Dim myArray(9) as String

Would give you an array of 10 String references (each pointing to Nothing).

If you're not sure of the size at declaration time, you can declare a String array like this:

Dim myArray() as String

And then you can point it at a properly-sized array of Strings later:

ReDim myArray(9) as String

ZombieSheep is right about using a List if you don't know the total size and you need to dynamically populate it. In VB.NET that would be:

Dim myList as New List(Of String)
myList.Add("foo")
myList.Add("bar")

And then to get an array from that List:

myList.ToArray()

• use a regex
• use parse which is kind of the opposite of format

This is in response to the above post by Efx:

If the URL already contains the var you want to change, then it is added yet again as a hidden field.

Here is a modification of that code as to prevent duplicating vars in the URL:

foreach ($_GET as $key => $value) {
    if ($key != "my_key") {
        echo("<input type='hidden' name='$key' value='$value'/>");
    }
}

Performance. If you want the original insertion order there are the LinkedXXX classes, which maintain an additional linked list in insertion order. Most of the time you don't care, so you use a HashXXX, or you want a natural order, so you use TreeXXX. In either of those cases why should you pay the extra cost of the linked list?

**multiple delete not working**

function delete_selection() 
{
        $id_array = array();
        $selection = $this->input->post("selection", TRUE);
        $id_array = explode("|", $selection);

        foreach ($id_array as $item):
            if ($item != ''):
                //DELETE ROW
                $this->db->where('entry_id', $item);
                $this->db->delete('helpline_entry');

git remote manpage is pretty straightforward:

• https://www.kernel.org/pub/software/scm/git/docs/git-remote.html

Use

Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream

Then do:    
$ git remote add upstream https://github.com/Foo/repos.git

or just update the URL directly:

$ git remote set-url upstream https://github.com/Foo/repos.git

or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).

...
[remote "upstream"]
    fetch = +refs/heads/*:refs/remotes/upstream/*
    url = https://github.com/foo/repos.git
...

* Regarding 'git remote rm' vs 'git remote remove' - this changed around git 1.7.10.3 / 1.7.12 2 - see

Log message

remote: prefer subcommand name 'remove' to 'rm'

All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.

'rm' is still supported and used in the test suite. It's just not
widely advertised.

Try this out: alert(col.firstChild.data)

Check this out for the difference between nodeValue and data: When working with text nodes should I use the "data", "nodeValue", "textContent" or "wholeText" field?

I'm guessing

x= data[:,0]
y= data[:,1]

You can use the following command:

git reset -- my-file.txt

which will update both the working copy of my-file.txt when added.

Disabling and Enabling All Foreign Keys

CREATE PROCEDURE pr_Disable_Triggers_v2
    @disable BIT = 1
AS
    DECLARE @sql VARCHAR(500)
        ,   @tableName VARCHAR(128)
        ,   @tableSchema VARCHAR(128)

    -- List of all tables
    DECLARE triggerCursor CURSOR FOR
        SELECT  t.TABLE_NAME AS TableName
            ,   t.TABLE_SCHEMA AS TableSchema
        FROM    INFORMATION_SCHEMA.TABLES t
        ORDER BY t.TABLE_NAME, t.TABLE_SCHEMA

    OPEN    triggerCursor
    FETCH NEXT FROM triggerCursor INTO @tableName, @tableSchema
    WHILE ( @@FETCH_STATUS = 0 )
    BEGIN

        SET @sql = 'ALTER TABLE ' + @tableSchema + '.[' + @tableName + '] '
        IF @disable = 1
            SET @sql = @sql + ' DISABLE TRIGGER ALL'
        ELSE
            SET @sql = @sql + ' ENABLE TRIGGER ALL'

        PRINT 'Executing Statement - ' + @sql
        EXECUTE ( @sql )

        FETCH NEXT FROM triggerCursor INTO @tableName, @tableSchema

    END

    CLOSE triggerCursor
    DEALLOCATE triggerCursor

First, the foreignKeyCursor cursor is declared as the SELECT statement that gathers the list of foreign keys and their table names. Next, the cursor is opened and the initial FETCH statement is executed. This FETCH statement will read the first row's data into the local variables @foreignKeyName and @tableName. When looping through a cursor, you can check the @@FETCH_STATUS for a value of 0, which indicates that the fetch was successful. This means the loop will continue to move forward so it can get each successive foreign key from the rowset. @@FETCH_STATUS is available to all cursors on the connection. So if you are looping through multiple cursors, it is important to check the value of @@FETCH_STATUS in the statement immediately following the FETCH statement. @@FETCH_STATUS will reflect the status for the most recent FETCH operation on the connection. Valid values for @@FETCH_STATUS are:

0 = FETCH was successful
-1 = FETCH was unsuccessful
-2 = the row that was fetched is missing

Inside the loop, the code builds the ALTER TABLE command differently depending on whether the intention is to disable or enable the foreign key constraint (using the CHECK or NOCHECK keyword). The statement is then printed as a message so its progress can be observed and then the statement is executed. Finally, when all rows have been iterated through, the stored procedure closes and deallocates the cursor.

A list is a chain of spaces that can be indexed by (0, 1, 2 .... etc). So if players was a list, players[0] or players[1] would have worked. If players is a dictionary, players["name"] would have worked.

The simplest way to do this is to change the part of the dict that is in datetime format to isoformat. That value will effectively be a string in isoformat which json is ok with.

v_dict = version.dict()
v_dict['created_at'] = v_dict['created_at'].isoformat()

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

Just define your action method like this

public string ThemePath()

and simply return the string itself.

The problem occurs because webpack-dev-server 2.4.4 adds a host check. You can disable it by adding this to your webpack config:

 devServer: {
    compress: true,
    disableHostCheck: true,   // That solved it

 }      

EDIT: Please note, this fix is insecure.

Please see the following answer for a secure solution: https://stackoverflow.com/a/43621275/5425585

select * from sysobjects where xtype='U'

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

Void is used as a keyword. The void pointer, also known as the generic pointer, is a special type of pointer that can be pointed at objects of any data type! A void pointer is declared like a normal pointer, using the void keyword as the pointer’s type:

General Syntax:

void* pointer_variable;

void *pVoid; // pVoid is a void pointer

A void pointer can point to objects of any data type:

int nValue;
float fValue;

struct Something
{
    int nValue;
    float fValue;
};

Something sValue;

void *pVoid;
pVoid = &nValue; // valid
pVoid = &fValue; // valid
pVoid = &sValue; // valid

However, because the void pointer does not know what type of object it is pointing to, it can not be dereferenced! Rather, the void pointer must first be explicitly cast to another pointer type before it is dereferenced.

int nValue = 5;
void *pVoid = &nValue;

// can not dereference pVoid because it is a void pointer

int *pInt = static_cast<int*>(pVoid); // cast from void* to int*

cout << *pInt << endl; // can dereference pInt

It is mentioned under "Index expressions".

An index expression on a map a of type map[K]V used in an assignment or initialization of the special form

v, ok = a[x] 
v, ok := a[x] 
var v, ok = a[x]

yields an additional untyped boolean value. The value of ok is true if the key x is present in the map, and false otherwise.

This code block is enough. Please don't forget to set delegate in viewDidLoad or by storyboard just before to use the following extension:

extension YOUR_VIEW_CONTROLLER: UITextViewDelegate {

func textViewDidBeginEditing (_ textView: UITextView) {
    if YOUR_TEXT_VIEW.text.isEmpty || YOUR_TEXT_VIEW.text == "YOUR DEFAULT PLACEHOLDER TEXT HERE" {
        YOUR_TEXT_VIEW.text = nil
        YOUR_TEXT_VIEW.textColor = .red // YOUR PREFERED COLOR HERE
    }
}
func textViewDidEndEditing (_ textView: UITextView) {
    if YOUR_TEXT_VIEW.text.isEmpty {
        YOUR_TEXT_VIEW.textColor = UIColor.gray // YOUR PREFERED PLACEHOLDER COLOR HERE
        YOUR_TEXT_VIEW.text =  "YOUR DEFAULT PLACEHOLDER TEXT HERE"
    }
}

}

Yes there is, since setState works in an asynchronous way. That means after calling setState the this.state variable is not immediately changed. so if you want to perform an action immediately after setting state on a state variable and then return a result, a callback will be useful

Consider the example below

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value });
  this.validateTitle();
},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

The above code may not work as expected since the title variable may not have mutated before validation is performed on it. Now you may wonder that we can perform the validation in the render() function itself but it would be better and a cleaner way if we can handle this in the changeTitle function itself since that would make your code more organised and understandable

In this case callback is useful

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value }, function() {
    this.validateTitle();
  });

},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

Another example will be when you want to dispatch and action when the state changed. you will want to do it in a callback and not the render() as it will be called everytime rerendering occurs and hence many such scenarios are possible where you will need callback.

Another case is a API Call

A case may arise when you need to make an API call based on a particular state change, if you do that in the render method, it will be called on every render onState change or because some Prop passed down to the Child Component changed.

In this case you would want to use a setState callback to pass the updated state value to the API call

....
changeTitle: function (event) {
  this.setState({ title: event.target.value }, () => this.APICallFunction());
},
APICallFunction: function () {
  // Call API with the updated value
}
....

To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.

class YourClass():

    def your_function(self, *args):

        self.callable_function(param) # if you need to pass any parameter

    def callable_function(self, *params): 
        print('Your param:', param)

I had this issue when I upgraded to v3.0.0.preview4, so a downgrade to a stable version fixed this.

The JVM is a "simulated machine" that can be installed on different systems. In this way, the same Java code can run on different systems, because it relies on the JVM, not on the operational system itself.

That is to say, this allows the programmer to communicate with the virtual system (JVM) and utilize its functions, instead of the specific machine and OS functions. Since Java only relies on JVM, it is platform independent (if the platform has JVM installed).

So in short, Java is not platform independent as such, it requires a JVM-installation for all systems it should run on. However, it will run on all systems that has the JVM installed.

driver.findElement(By.id("Value")).sendKeys(Keys.RETURN); or driver.findElement(By.id("Value")).sendKeys(Keys.ENTER);

I just came across this. The correct answer is:

awk 'BEGIN{FS=OFS=","} {gsub(/^[[:space:]]+|[[:space:]]+$/,"",$2)} 1'

For Laravel 5.2 (previous versions I did not use)

Paste the code into the file app\Http\Controllers\Auth\AurhController.php

   /**

 *
 * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
 */
public function showLoginForm()
{
    $view = property_exists($this, 'loginView')
        ? $this->loginView : 'auth.authenticate';
    if (view()->exists($view)) {
        return view($view);
    }
    /**
     * seve the previous page in the session
     */
    $previous_url = Session::get('_previous.url');
    $ref = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : '';
    $ref = rtrim($ref, '/');
    if ($previous_url != url('login')) {
        Session::put('referrer', $ref);
        if ($previous_url == $ref) {
            Session::put('url.intended', $ref);
        }
    }
    /**
     * seve the previous page in the session
     * end
     */
    return view('auth.login');
}
/**
 * Overrides method in class 'AuthenticatesUsers'
 *
 * @param Request $request
 * @param $throttles
 *
 * @return \Illuminate\Http\RedirectResponse
 */
protected function handleUserWasAuthenticated(Request $request, $throttles)
{
    if ($throttles) {
        $this->clearLoginAttempts($request);
    }
    if (method_exists($this, 'authenticated')) {
        return $this->authenticated($request, Auth::guard($this->getGuard())->user());
    }
    /*return to the previous page*/
    return redirect()->intended(Session::pull('referrer'));
    /*return redirect()->intended($this->redirectPath()); /*Larevel default*/
}

And import namespace: use Session;

If you have not made any changes to the file app\Http\Controllers\Auth\AurhController.php, you can just replace it with the file from the GitHub

Make sure you have the es2015 babel preset installed.

An example package.json devDependencies is:

"devDependencies": {
  "babel-core": "^6.0.20",
  "babel-loader": "^6.0.1",
  "babel-preset-es2015": "^6.0.15",
  "babel-preset-react": "^6.0.15",
  "babel-preset-stage-0": "^6.0.15",
  "webpack": "^1.9.6",
  "webpack-dev-middleware": "^1.2.0",
  "webpack-hot-middleware": "^2.0.0"
},

Now configure babel-loader in your webpack config:

{ test: /\.js$/, loader: 'babel-loader', exclude: /node_modules/ }

add a .babelrc file to the root of your project where the node modules are:

{
  "presets": ["es2015", "stage-0", "react"]
}

From Effective Go:

Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.

Slices and arrays are always evaluated during runtime:

var TestSlice = []float32 {.03, .02}
var TestArray = [2]float32 {.03, .02}
var TestArray2 = [...]float32 {.03, .02}

[...] tells the compiler to figure out the length of the array itself. Slices wrap arrays and are easier to work with in most cases. Instead of using constants, just make the variables unaccessible to other packages by using a lower case first letter:

var ThisIsPublic = [2]float32 {.03, .02}
var thisIsPrivate = [2]float32 {.03, .02}

thisIsPrivate is available only in the package it is defined. If you need read access from outside, you can write a simple getter function (see Getters in golang).

Instead of wading through the description of all the options, you can jump to 3.4.3 Short Options Cross Reference under the info tar command.

x means --extract. v means --verbose. f means --file. z means --gzip. You can combine one-letter arguments together, and f takes an argument, the filename. There is something you have to watch out for:

Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below). When short options are clumped as a set, use one (single) dash for them all, e.g., ''tar' -cvf'. Only the last option in such a set is allowed to have an argument(1).

---

This old way of writing 'tar' options can surprise even experienced users. For example, the two commands:

 tar cfz archive.tar.gz file
 tar -cfz archive.tar.gz file

are quite different. The first example uses 'archive.tar.gz' as the value for option 'f' and recognizes the option 'z'. The second example, however, uses 'z' as the value for option 'f' -- probably not what was intended.

You will have to download file from here https://commons.apache.org/proper/commons-io/download_io.cgi and select https://prnt.sc/tk5ewt

Now, Next add this downloaded files into your project:

Right click to your project ->Build path->Configure BuidPath -> https://prnt.sc/tk5d93

print_r($this->session->userdata); 

or

print_r($this->session->all_userdata());

I solved the problem. In Home Ubuntu, I deleted the .gradle folder and downloaded it again. I hope it is useful

@Harris's answer is great, I've implemented it as a separate subclass of EditText, which can make it easier to use if your code already adds TextChangedListeners.

Also, I've tweaked it so that, if you already use any Compound Drawables, it leaves them intact.

Code is here, for anyone who needs it:

package com.companyname.your

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.EditText;

public class ClearableEditText extends EditText {

    public String defaultValue = "";
    final Drawable imgX = getResources().getDrawable(android.R.drawable.presence_offline ); // X image


    public ClearableEditText(Context context) {
        super(context);

        init();
    }

    public ClearableEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

        init();
    }

    public ClearableEditText(Context context, AttributeSet attrs) {
        super(context, attrs);

        init();
    }


    void init()  {

        // Set bounds of our X button
        imgX.setBounds(0, 0, imgX.getIntrinsicWidth(), imgX.getIntrinsicHeight());      

        // There may be initial text in the field, so we may need to display the button
        manageClearButton();

        this.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                ClearableEditText et = ClearableEditText.this;

                // Is there an X showing?
                if (et.getCompoundDrawables()[2] == null) return false;
                // Only do this for up touches
                if (event.getAction() != MotionEvent.ACTION_UP) return false;
                // Is touch on our clear button?
                if (event.getX() > et.getWidth() - et.getPaddingRight() - imgX.getIntrinsicWidth()) {
                    et.setText("");
                    ClearableEditText.this.removeClearButton();
                }
                return false;
            }
        });

        this.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

                ClearableEditText.this.manageClearButton();
            }

            @Override
            public void afterTextChanged(Editable arg0) {
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }
        });
    }

    void manageClearButton() {
        if (this.getText().toString().equals("") )
            removeClearButton();
        else
            addClearButton();
    }
    void addClearButton() {
        this.setCompoundDrawables(this.getCompoundDrawables()[0], 
                this.getCompoundDrawables()[1],
                imgX,
                this.getCompoundDrawables()[3]);
    }
    void removeClearButton() {
        this.setCompoundDrawables(this.getCompoundDrawables()[0], 
                this.getCompoundDrawables()[1],
                null,
                this.getCompoundDrawables()[3]);
    }

}

There are several libraries available solving this problem, but the simplest is probably to use Boost Tokenizer:

#include <iostream>
#include <string>
#include <boost/tokenizer.hpp>
#include <boost/foreach.hpp>

typedef boost::tokenizer<boost::char_separator<char> > tokenizer;

std::string str("denmark;sweden;india;us");
boost::char_separator<char> sep(";");
tokenizer tokens(str, sep);

BOOST_FOREACH(std::string const& token, tokens)
{
    std::cout << "<" << *tok_iter << "> " << "\n";
}

<h:button>

The <h:button> generates a HTML <input type="button">. The generated element uses JavaScript to navigate to the page given by the attribute outcome, using a HTTP GET request.

E.g.

<h:button value="GET button" outcome="otherpage" />

will generate

<input type="button" onclick="window.location.href='/contextpath/otherpage.xhtml'; return false;" value="GET button" />

Even though this ends up in a (bookmarkable) URL change in the browser address bar, this is not SEO-friendly. Searchbots won't follow the URL in the onclick. You'd better use a <h:outputLink> or <h:link> if SEO is important on the given URL. You could if necessary throw in some CSS on the generated HTML <a> element to make it to look like a button.

Do note that while you can put an EL expression referring a method in outcome attribute as below,

<h:button value="GET button" outcome="#{bean.getOutcome()}" />

it will not be invoked when you click the button. Instead, it is already invoked when the page containing the button is rendered for the sole purpose to obtain the navigation outcome to be embedded in the generated onclick code. If you ever attempted to use the action method syntax as in outcome="#{bean.action}", you would already be hinted by this mistake/misconception by facing a javax.el.ELException: Could not find property actionMethod in class com.example.Bean.

If you intend to invoke a method as result of a POST request, use <h:commandButton> instead, see below. Or if you intend to invoke a method as result of a GET request, head to Invoke JSF managed bean action on page load or if you also have GET request parameters via <f:param>, How do I process GET query string URL parameters in backing bean on page load?

<h:commandButton>

The <h:commandButton> generates a HTML <input type="submit"> button which submits by default the parent <h:form> using HTTP POST method and invokes the actions attached to action, actionListener and/or <f:ajax listener>, if any. The <h:form> is required.

E.g.

<h:form id="form">
    <h:commandButton id="button" value="POST button" action="otherpage" />
</h:form>

will generate

<form id="form" name="form" method="post" action="/contextpath/currentpage.xhtml" enctype="application/x-www-form-urlencoded">
    <input type="hidden" name="form" value="form" />
    <input type="submit" name="form:button" value="POST button" />
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="...." autocomplete="off" />
</form>

Note that it thus submits to the current page (the form action URL will show up in the browser address bar). It will afterwards forward to the target page, without any change in the URL in the browser address bar. You could add ?faces-redirect=true parameter to the outcome value to trigger a redirect after POST (as per the Post-Redirect-Get pattern) so that the target URL becomes bookmarkable.

The <h:commandButton> is usually exclusively used to submit a POST form, not to perform page-to-page navigation. Normally, the action points to some business action, such as saving the form data in DB, which returns a String outcome.

<h:commandButton ... action="#{bean.save}" />

with

public String save() {
    // ...
    return "otherpage";
}

Returning null or void will bring you back to the same view. Returning an empty string also, but it would recreate any view scoped bean. These days, with modern JSF2 and <f:ajax>, more than often actions just return to the same view (thus, null or void) wherein the results are conditionally rendered by ajax.

public void save() {
    // ...
}

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.

What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?

You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.

It's not possible, but that's just because an omission. It isn't something that "doesn't make sense" as a lot of people seem to claim. To be clear, I'm talking about something like this:

struct Base {
  static virtual void sayMyName() {
    cout << "Base\n";
  }
};

struct Derived : public Base {
  static void sayMyName() override {
    cout << "Derived\n";
  }
};

void foo(Base *b) {
  b->sayMyName();
  Derived::sayMyName(); // Also would work.
}

This is 100% something that could be implemented (it just hasn't), and I'd argue something that is useful.

Consider how normal virtual functions work. Remove the statics and add in some other stuff and we have:

struct Base {
  virtual void sayMyName() {
    cout << "Base\n";
  }
  virtual void foo() {
  }
  int somedata;
};

struct Derived : public Base {
  void sayMyName() override {
    cout << "Derived\n";
  }
};

void foo(Base *b) {
  b->sayMyName();
}

This works fine and basically what happens is the compiler makes two tables, called VTables, and assigns indices to the virtual functions like this

enum Base_Virtual_Functions {
  sayMyName = 0;
  foo = 1;
};

using VTable = void*[];

const VTable Base_VTable = {
  &Base::sayMyName,
  &Base::foo
};

const VTable Derived_VTable = {
  &Derived::sayMyName,
  &Base::foo
};

Next each class with virtual functions is augmented with another field that points to its VTable, so the compiler basically changes them to be like this:

struct Base {
  VTable* vtable;
  virtual void sayMyName() {
    cout << "Base\n";
  }
  virtual void foo() {
  }
  int somedata;
};

struct Derived : public Base {
  VTable* vtable;
  void sayMyName() override {
    cout << "Derived\n";
  }
};

Then what actually happens when you call b->sayMyName()? Basically this:

b->vtable[Base_Virtual_Functions::sayMyName](b);

(The first parameter becomes this.)

Ok fine, so how would it work with static virtual functions? Well what's the difference between static and non-static member functions? The only difference is that the latter get a this pointer.

We can do exactly the same with static virtual functions - just remove the this pointer.

b->vtable[Base_Virtual_Functions::sayMyName]();

This could then support both syntaxes:

b->sayMyName(); // Prints "Base" or "Derived"...
Base::sayMyName(); // Always prints "Base".

So ignore all the naysayers. It does make sense. Why isn't it supported then? I think it's because it has very little benefit and could even be a little confusing.

The only technical advantage over a normal virtual function is that you don't need to pass this to the function but I don't think that would make any measurable difference to performance.

It does mean you don't have a separate static and non-static function for cases when you have an instance, and when you don't have an instance, but also it might be confusing that it's only really "virtual" when you use the instance call.

If you want to scan input fast without getting confused into Scanner class nextLine() method , Use Custom Input Scanner for it .

Code :

class ScanReader {
/**
* @author Nikunj Khokhar
*/
    private byte[] buf = new byte[4 * 1024];
    private int index;
    private BufferedInputStream in;
    private int total;

    public ScanReader(InputStream inputStream) {
        in = new BufferedInputStream(inputStream);
    }

    private int scan() throws IOException {
        if (index >= total) {
            index = 0;
            total = in.read(buf);
            if (total <= 0) return -1;
        }
        return buf[index++];
    }
    public char scanChar(){
        int c=scan();
        while (isWhiteSpace(c))c=scan();
        return (char)c;
    }


    public int scanInt() throws IOException {
        int integer = 0;
        int n = scan();
        while (isWhiteSpace(n)) n = scan();
        int neg = 1;
        if (n == '-') {
            neg = -1;
            n = scan();
        }
        while (!isWhiteSpace(n)) {
            if (n >= '0' && n <= '9') {
                integer *= 10;
                integer += n - '0';
                n = scan();
            }
        }
        return neg * integer;
    }

    public String scanString() throws IOException {
        int c = scan();
        while (isWhiteSpace(c)) c = scan();
        StringBuilder res = new StringBuilder();
        do {
            res.appendCodePoint(c);
            c = scan();
        } while (!isWhiteSpace(c));
        return res.toString();
    }

    private boolean isWhiteSpace(int n) {
        if (n == ' ' || n == '\n' || n == '\r' || n == '\t' || n == -1) return true;
        else return false;
    }

    public long scanLong() throws IOException {
        long integer = 0;
        int n = scan();
        while (isWhiteSpace(n)) n = scan();
        int neg = 1;
        if (n == '-') {
            neg = -1;
            n = scan();
        }
        while (!isWhiteSpace(n)) {
            if (n >= '0' && n <= '9') {
                integer *= 10;
                integer += n - '0';
                n = scan();
            }
        }
        return neg * integer;
    }

    public void scanLong(long[] A) throws IOException {
        for (int i = 0; i < A.length; i++) A[i] = scanLong();
    }

    public void scanInt(int[] A) throws IOException {
        for (int i = 0; i < A.length; i++) A[i] = scanInt();
    }

    public double scanDouble() throws IOException {
        int c = scan();
        while (isWhiteSpace(c)) c = scan();
        int sgn = 1;
        if (c == '-') {
            sgn = -1;
            c = scan();
        }
        double res = 0;
        while (!isWhiteSpace(c) && c != '.') {
            if (c == 'e' || c == 'E') {
                return res * Math.pow(10, scanInt());
            }
            res *= 10;
            res += c - '0';
            c = scan();
        }
        if (c == '.') {
            c = scan();
            double m = 1;
            while (!isWhiteSpace(c)) {
                if (c == 'e' || c == 'E') {
                    return res * Math.pow(10, scanInt());
                }
                m /= 10;
                res += (c - '0') * m;
                c = scan();
            }
        }
        return res * sgn;
    }

}

Advantages :

• Scans Input faster than BufferReader
• Reduces Time Complexity
• Flushes Buffer for every next input

Methods :

• scanChar() - scan single character
• scanInt() - scan Integer value
• scanLong() - scan Long value
• scanString() - scan String value
• scanDouble() - scan Double value
• scanInt(int[] array) - scans complete Array(Integer)
• scanLong(long[] array) - scans complete Array(Long)

Usage :

1. Copy the Given Code below your java code.
2. Initialise Object for Given Class

ScanReader sc = new ScanReader(System.in); 3. Import necessary Classes :

import java.io.BufferedInputStream; import java.io.IOException; import java.io.InputStream; 4. Throw IOException from your main method to handle Exception 5. Use Provided Methods. 6. Enjoy

Example :

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
class Main{
    public static void main(String... as) throws IOException{
        ScanReader sc = new ScanReader(System.in);
        int a=sc.scanInt();
        System.out.println(a);
    }
}
class ScanReader....

I think the best way is:

data: "{'Ids':['2','2']}"

To read this values Ids[0], Ids[1].

import java.io.*;


public class FileRead {


    public static void main(String[] args) throws IOException {


        File f=new File("C:\\Documents and Settings\\abc\\Desktop\\abc.pdf");

        OutputStream oos = new FileOutputStream("test.pdf");

        byte[] buf = new byte[8192];

        InputStream is = new FileInputStream(f);

        int c = 0;

        while ((c = is.read(buf, 0, buf.length)) > 0) {
            oos.write(buf, 0, c);
            oos.flush();
        }

        oos.close();
        System.out.println("stop");
        is.close();

    }

}

The easiest way so far. Hope this helps.

Alternative answer, you can use this JDBC URL directly in your datasource configuration:

jdbc:mysql://yourserver:3306/yourdatabase?zeroDateTimeBehavior=convertToNull

Edit:

Source: MySQL Manual

Datetimes with all-zero components (0000-00-00 ...) — These values can not be represented reliably in Java. Connector/J 3.0.x always converted them to NULL when being read from a ResultSet.

Connector/J 3.1 throws an exception by default when these values are encountered as this is the most correct behavior according to the JDBC and SQL standards. This behavior can be modified using the zeroDateTimeBehavior configuration property. The allowable values are:

• exception (the default), which throws an SQLException with an SQLState of S1009.
• convertToNull, which returns NULL instead of the date.
• round, which rounds the date to the nearest closest value which is 0001-01-01.

Update: Alexander reported a bug affecting mysql-connector-5.1.15 on that feature. See CHANGELOGS on the official website.

After spending the day I realized it was a simple change in Project Settings

File -> Project Settings... -> Build System -> Legacy Build System.

In a project setting, you will see Build System named drop down and in that drop down select Legacy Build System

You can use setTimeout to do this

function myFunction() {
    // your code to run after the timeout
}

// stop for sometime if needed
setTimeout(myFunction, 5000);

Actually I did it by uncommenting extension=php_curl.dll in the xampp\apache\bin\php.ini file.

Yes, you can declare a class you cannot instantiate by itself with only methods that already have implementations. This would be useful if you wanted to add abstract methods in the future, or if you did not want the class to be directly instantiated even though it has no abstract properties.

For security reasons most browsers do not allow to modify the clipboard (except IE, of course...).

The only way to make a copy-to-clipboard function cross-browser compatible is to use Flash.

public class Multipart{
    private final Map<String, String> headrs;
    private String url;
    private HttpURLConnection con;
    private OutputStream os;

    private String delimiter = "--";
    private String boundary = "TRR" + Long.toString(System.currentTimeMillis()) + "TRR";

    public Multipart (String url, Map<String, String> headers) {
        this.url = url;
        this.headrs = headers;
    }

    public void connectForMultipart() throws Exception {
        con = (HttpURLConnection) (new URL(url)).openConnection();
        con.setRequestMethod("POST");
        con.setDoInput(true);
        con.setDoOutput(true);
        con.setRequestProperty("Connection", "Keep-Alive");
        for (Map.Entry<String, String> entry : headrs.entrySet()) {
            con.setRequestProperty(entry.getKey(), entry.getValue());
        }
        con.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
        con.connect();
        os = con.getOutputStream();
    }

    public void addFormPart(String paramName, String value) throws Exception {
        writeParamData(paramName, value);
    }

    public void addFilePart(String paramName, String fileName, byte[] data) throws Exception {
        os.write((delimiter + boundary + "\r\n").getBytes());
        os.write(("Content-Disposition: form-data; name=\"" + paramName + "\"; filename=\"" + fileName + "\"\r\n").getBytes());
        os.write(("Content-Type: application/octet-stream\r\n").getBytes());
        os.write(("Content-Transfer-Encoding: binary\r\n").getBytes());
        os.write("\r\n".getBytes());

        os.write(data);

        os.write("\r\n".getBytes());
    }

    public void finishMultipart() throws Exception {
        os.write((delimiter + boundary + delimiter + "\r\n").getBytes());
    }


    public String getResponse() throws Exception {
        InputStream is = con.getInputStream();
        byte[] b1 = new byte[1024];
        StringBuffer buffer = new StringBuffer();

        while (is.read(b1) != -1)
            buffer.append(new String(b1));

        con.disconnect();

        return buffer.toString();
    }


    private void writeParamData(String paramName, String value) throws Exception {


        os.write((delimiter + boundary + "\r\n").getBytes());
        os.write("Content-Type: text/plain\r\n".getBytes());//;charset=utf-8
        os.write(("Content-Disposition: form-data; name=\"" + paramName + "\"\r\n").getBytes());
        ;
        os.write(("\r\n" + value + "\r\n").getBytes());


    }
}

Then call below

Multipart multipart = new Multipart(url__, map);
            multipart .connectForMultipart();
multipart .addFormPart(entry.getKey(), entry.getValue());
multipart .addFilePart(KeyName, "FileName", imagedata);
multipart .finishMultipart();

I think it really depends on why this error is given. It may be the bitness issue, but it may also be because of a deinstaller bug that leaves registry entries behind.

I just had this case because I need two versions of Python on my system. When I tried to install SCons (using Python2), the .msi installer failed, saying it only found Python3 in the registry. So I uninstalled it, with the result that no Python was found at all. Frustrating! (workaround: install SCons with pip install --egg --upgrade scons)

Anyway, I'm sure there are threads on that phenomenon. I just thought it would fit here because this was one of my top search results.

I was looking for something like the rails approach used in ActiveRecord to_json and implemented something similar using this Mixin after being unsatisfied with other suggestions. It handles nested models, and including or excluding attributes of the top level or nested models.

class Serializer(object):

    def serialize(self, include={}, exclude=[], only=[]):
        serialized = {}
        for key in inspect(self).attrs.keys():
            to_be_serialized = True
            value = getattr(self, key)
            if key in exclude or (only and key not in only):
                to_be_serialized = False
            elif isinstance(value, BaseQuery):
                to_be_serialized = False
                if key in include:
                    to_be_serialized = True
                    nested_params = include.get(key, {})
                    value = [i.serialize(**nested_params) for i in value]

            if to_be_serialized:
                serialized[key] = value

        return serialized

Then, to get the BaseQuery serializable I extended BaseQuery

class SerializableBaseQuery(BaseQuery):

    def serialize(self, include={}, exclude=[], only=[]):
        return [m.serialize(include, exclude, only) for m in self]

For the following models

class ContactInfo(db.Model, Serializer):
    id = db.Column(db.Integer, primary_key=True)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'))
    full_name = db.Column(db.String())
    source = db.Column(db.String())
    source_id = db.Column(db.String())

    email_addresses = db.relationship('EmailAddress', backref='contact_info', lazy='dynamic')
    phone_numbers = db.relationship('PhoneNumber', backref='contact_info', lazy='dynamic')


class EmailAddress(db.Model, Serializer):
    id = db.Column(db.Integer, primary_key=True)
    email_address = db.Column(db.String())
    type = db.Column(db.String())
    contact_info_id = db.Column(db.Integer, db.ForeignKey('contact_info.id'))


class PhoneNumber(db.Model, Serializer):
    id = db.Column(db.Integer, primary_key=True)
    phone_number = db.Column(db.String())
    type = db.Column(db.String())
    contact_info_id = db.Column(db.Integer, db.ForeignKey('contact_info.id'))

    phone_numbers = db.relationship('Invite', backref='phone_number', lazy='dynamic')

You could do something like

@app.route("/contact/search", methods=['GET'])
def contact_search():
    contact_name = request.args.get("name")
    matching_contacts = ContactInfo.query.filter(ContactInfo.full_name.like("%{}%".format(contact_name)))

    serialized_contact_info = matching_contacts.serialize(
        include={
            "phone_numbers" : {
                "exclude" : ["contact_info", "contact_info_id"]
            },
            "email_addresses" : {
                "exclude" : ["contact_info", "contact_info_id"]
            }
        }
    )

    return jsonify(serialized_contact_info)

Here is how I downgrade KOPS (which does not support versioning)

# brew has a git repo on your localhost
cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core

git remote -v

# find the version of kops.rb you need
git log Formula/kops.rb

# checkout old commit
# kops: update 1.18.1 bottle.
git checkout 2f0ede7f27dfc074d5b5493894f3468f27cc73f0 -- Formula/kops.rb

brew unlink kops
brew install kops

# now we have old version installed
ls -1 /usr/local/Cellar/kops/

Since Java8 this can be done even cleaner using a combination of Comparator and Lambda expressions

For Example:

class Student{

    private String name;
    private List<Score> scores;

    // +accessor methods
}

class Score {

    private int grade;
    // +accessor methods
}

    Collections.sort(student.getScores(), Comparator.comparing(Score::getGrade);

I'm developing an UWP application which connects to a MQTT broker in the LAN. I go a similar error.

MQTTnet.Exceptions.MqttCommunicationException: 'An attempt was made to access a socket in a way forbidden by its access permissions [::ffff:xxx.xxx.xxx.xxx]:1883'

ExtendedSocketException: An attempt was made to access a socket in a way forbidden by its access permissions [::ffff:xxx.xxx.xxx.xxx]:1883

Turned out that I forgot to give the app the correct capabilites ...

The WPF RichTextBox has a Document property for setting the content a la MSDN:

// Create a FlowDocument to contain content for the RichTextBox.
        FlowDocument myFlowDoc = new FlowDocument();

        // Add paragraphs to the FlowDocument.
        myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 1")));
        myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 2")));
        myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 3")));
        RichTextBox myRichTextBox = new RichTextBox();

        // Add initial content to the RichTextBox.
        myRichTextBox.Document = myFlowDoc;

You can just use the AppendText method though if that's all you're after.

Hope that helps.

the button 'Use same account' below thee main window will fill in all the textboxes automatically. this worked fpr me.

The easiest way is to have

if (document.location.search.indexOf('yourtext=') >= 0) {
    // your code
} else {
    // what happens?
}

indexOf()

The indexOf(text) function returns

• A WHOLE NUMBER BELOW 0 when the text passed in the function is not in whatever variable or string you are looking for - in this case document.location.search.
• A WHOLE NUMBER EQUAL TO 0 OR HIGHER when the text passed in the function is in whatever variable or string you are looking for - in this case document.location.search.

I hope this was useful, @gumbo

SQLite doesn't support removing or modifying columns, apparently. But do remember that column data types aren't rigid in SQLite, either.

See also:

• SQLite Modify Column

For me the filename involved was appended with a querystring, which this function didn't like.

$path = 'path/to/my/file.js?v=2'

Solution was to chop that off first:

$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

Just Remove $ in to compact method ,
return view('page',compact('member'))

$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL,'https://www.xxxSite/get_quote/ajaxGetQuoteJSON.jsp?symbol=IRCTC&series=EQ');
//Set the GET method by giving 0 value and for POST set as 1
//curl_setopt($curl_handle, CURLOPT_POST, 0);
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
$query = curl_exec($curl_handle);
$data = json_decode($query, true);
curl_close($curl_handle);

//print complete object, just echo the variable not work so you need to use print_r to show the result
echo print_r( $data);
//at first layer
echo $data["tradedDate"];
//Inside the second layer
echo $data["data"][0]["companyName"];

Some time you might get 405, set the method type correctly.

You can also pipe to a while loop that can do multiple actions on the file which find locates. So here is one for looking in jar archives for a given java class file in folder with a large distro of jar files

find /usr/lib/eclipse/plugins -type f -name \*.jar | while read jar; do echo $jar; jar tf $jar | fgrep IObservableList ; done

the key point being that the while loop contains multiple commands referencing the passed in file name separated by semicolon and these commands can include pipes. So in that example I echo the name of the matching file then list what is in the archive filtering for a given class name. The output looks like:

/usr/lib/eclipse/plugins/org.eclipse.core.contenttype.source_3.4.1.R35x_v20090826-0451.jar /usr/lib/eclipse/plugins/org.eclipse.core.databinding.observable_1.2.0.M20090902-0800.jar org/eclipse/core/databinding/observable/list/IObservableList.class /usr/lib/eclipse/plugins/org.eclipse.search.source_3.5.1.r351_v20090708-0800.jar /usr/lib/eclipse/plugins/org.eclipse.jdt.apt.core.source_3.3.202.R35x_v20091130-2300.jar /usr/lib/eclipse/plugins/org.eclipse.cvs.source_1.0.400.v201002111343.jar /usr/lib/eclipse/plugins/org.eclipse.help.appserver_3.1.400.v20090429_1800.jar

in my bash shell (xubuntu10.04/xfce) it really does make the matched classname bold as the fgrep highlights the matched string; this makes it really easy to scan down the list of hundreds of jar files that were searched and easily see any matches.

on windows you can do the same thing with:

for /R %j in (*.jar) do @echo %j & @jar tf %j | findstr IObservableList

note that in that on windows the command separator is '&' not ';' and that the '@' suppresses the echo of the command to give a tidy output just like the linux find output above; although findstr is not make the matched string bold so you have to look a bit closer at the output to see the matched class name. It turns out that the windows 'for' command knows quite a few tricks such as looping through text files...

I think the reason those suggesting using the C:\PROGRA~1 name have received downvotes is because those names are seen as a legacy feature of Windows best forgotten, which may also be unstable, at least between different installations, although probably not on the same machine.

Also, as someone pointed out in a comment to another answer, Windows can be configured not to have the 8.3 legacy names in the filesystem at all.

I have used the above option to .hide entries from 2 drops down boxes (first you select the city, then you selected the area within that city). It works fine on screen but the hidden options are still selectable via keyboard inputs.

Here's a short PowerShell script to do what you probably expect:

$sourceNugetExe = "https://dist.nuget.org/win-x86-commandline/latest/nuget.exe"
$targetNugetExe = "$rootPath\nuget.exe"
Invoke-WebRequest $sourceNugetExe -OutFile $targetNugetExe
Set-Alias nuget $targetNugetExe -Scope Global -Verbose

Note that Invoke-WebRequest cmdlet arrived with PowerShell v3.0. This article gives the idea.

I managed to find a solution using css/jQuery that I'm comfortable with. The original issue: I had to force the visibility to be shown while animating as I have elements hanging outside the area. Doing so, made large blocks of text now hang outside the content area during animation as well.

The solution was to start the main text elements with an opacity of 0 and use addClass to inject and transition to an opacity of 1. Then removeClass when clicked on again.

I'm sure there's an all jQquery way to do this. I'm just not the guy to do it. :)

So in it's most basic form...

.slideDown().addClass("load");
.slideUp().removeClass("load");

Thanks for the help everyone.

Here is a very simple class NumberInWords.java that can have the job done very easily:

String numberInWords = NumberInWords.convertNumberToWords(27546); //twenty seven thousand and five hundred forty six

It's important to know that this class is only capable of converting int datatype.

As other's have mentioned, PHP's cURL functions will allow you to perform advanced HTTP requests. You can also use file_get_contents to access REST APIs:

$payload = file_get_contents('http://api.someservice.com/SomeMethod?param=value');

Starting with PHP 5 you can also create a stream context which will allow you to change headers or post data to the service.

rename might not be in every system. so if you don't have it, use the shell this example in bash shell

for f in fgh*; do mv "$f" "${f/fgh/xxx}";done

Where does the variable results come from?

This block:

foreach (People p in ppl.results) {
    list.Add(results.name);
    list.Add(results.email);
    list2d.Add(list);
}

Should probably read more like:

foreach (People p in ppl.results) {
    var list = new List<string>();
    list.Add(p.name);
    list.Add(p.email);
    list2d.Add(list);
}

IMDB themselves seem to distribute data, but only in text files:

http://www.imdb.com/interfaces

there are several APIs around this that you can Google. Screen scraping is explicitly forbidden. A official API seems to be in the works, but has been that for years already.

add to your global file this action.

protected void Application_Start() {
   BundleConfig.RegisterBundles(BundleTable.Bundles);
}

you can do that

var filteredFileList = fileList.Where(fl => filterList.Contains(fl.ToString()));

I have a Windows service, and I added the following line to the constructor for my service:

using System.Diagnostics;
try {
    Process p = Process.Start(@"C:\Windows\system32\calc.exe");
} catch {
    Debugger.Break();
}

When I tried to run this, the Process.Start() call was made, and no exception occurred. However, the calc.exe application did not show up. In order to make it work, I had edit the properties for my service in the Service Control Manager to enable interaction with the desktop. After doing that, the Process.Start() opened calc.exe as expected.

But as others have said, interaction with the desktop is frowned upon by Microsoft and has essentially been disabled in Vista. So even if you can get it to work in XP, I don't know that you'll be able to make it work in Vista.

Here are a few modern approaches:

• Approach 1 - Combination of viewport relative units / calc().

  The expression calc(100vh - 30px) represents the remaining height. Where 100vh is the height of the browser and the usage of calc() effectively displaces the height of the other element.

  Example Here

  _x000D_

  _x000D_

  body {_x000D_
      margin: 0;_x000D_
  }_x000D_
  .banner {_x000D_
      background: #f00;_x000D_
      height: 30px;_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;_x000D_
      background: #000;_x000D_
      border: none;_x000D_
      height: calc(100vh - 30px);_x000D_
      width: 100%;_x000D_
  }

  _x000D_

  <div class="banner"></div>_x000D_
  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

  Support for calc() here; support for viewport relative units here.

• Approach 2 - Flexbox approach

  Example Here

  Set the display of the common parent element to flex, along with flex-direction: column (assuming you want the elements to stack on top of each other). Then set flex-grow: 1 on the child iframe element in order for it to fill the remaining space.

  _x000D_

  _x000D_

  body {_x000D_
      margin: 0;_x000D_
  }_x000D_
  .parent {_x000D_
      display: flex;_x000D_
      flex-direction: column;_x000D_
      min-height: 100vh;_x000D_
  }_x000D_
  .parent .banner {_x000D_
      background: #f00;_x000D_
      width: 100%;_x000D_
      height: 30px;_x000D_
  }_x000D_
  .parent iframe {_x000D_
      background: #000;_x000D_
      border: none;_x000D_
      flex-grow: 1;_x000D_
  }

  _x000D_

  <div class="parent">_x000D_
      <div class="banner"></div>_x000D_
      <iframe></iframe>_x000D_
  </div>

  _x000D_

  _x000D_
  _x000D_

  Since this approach has less support¹, I'd suggest going with the aforementioned approach.

¹_{Though it seems to work in Chrome/FF, it doesn't work in IE (the first method works in all current browsers).}

Localization of date string:

Based on redsonic's post:

private String localizeDate(String inputdate, Locale locale) { 

    Date date = new Date();
    SimpleDateFormat dateFormatCN = new SimpleDateFormat("dd-MMM-yyyy", locale);       
    SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy");


    try {
        date = dateFormat.parse(inputdate);
    } catch (ParseException e) {
        log.warn("Input date was not correct. Can not localize it.");
        return inputdate;
    }
    return dateFormatCN.format(date);
}

String localizedDate = localizeDate("05-Sep-2013", new Locale("zh","CN"));

will be like 05-??-2013

Have a look at ?options and use warn:

options( warn = -1 )

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

You can see in here: http://apidock.com/rails/ActionView/Helpers/FormBuilder/select

Or here: http://apidock.com/rails/ActionView/Helpers/FormOptionsHelper/select

Select tag has maximun 4 agrument, and last agrument is html option, it mean you can put class, require, selection option in here.

= f.select :sms_category_id, @sms_category_collect, {}, {class: 'form-control', required: true, selected: @set}

You can do direct SQL to have a single query for both tables. I'll provide a sanitized query example to hopefully keep people from putting variables directly into the string itself (SQL injection danger), even though this example didn't specify the need for it:

@results = []
ActiveRecord::Base.connection.select_all(
  ActiveRecord::Base.send(:sanitize_sql_array, 
   ["... your SQL query goes here and ?, ?, ? are replaced...;", a, b, c])
).each do |record|
  # instead of an array of hashes, you could put in a custom object with attributes
  @results << {col_a_name: record["col_a_name"], col_b_name: record["col_b_name"], ...}
end

Edit: as Huy said, a simple way is ActiveRecord::Base.connection.execute("..."). Another way is ActiveRecord::Base.connection.exec_query('...').rows. And you can use native prepared statements, e.g. if using postgres, prepared statement can be done with raw_connection, prepare, and exec_prepared as described in https://stackoverflow.com/a/13806512/178651

You can also put raw SQL fragments into ActiveRecord relational queries: http://guides.rubyonrails.org/active_record_querying.html and in associations, scopes, etc. You could probably construct the same SQL with ActiveRecord relational queries and can do cool things with ARel as Ernie mentions in http://erniemiller.org/2010/03/28/advanced-activerecord-3-queries-with-arel/. And, of course there are other ORMs, gems, etc.

If this is going to be used a lot and adding indices won't cause other performance/resource issues, consider adding an index in the DB for payment_details.created_at and for payment_errors.created_at.

If lots of records and not all records need to show up at once, consider using pagination:

• https://www.ruby-toolbox.com/categories/pagination
• https://github.com/mislav/will_paginate

If you need to paginate, consider creating a view in the DB first called payment_records which combines the payment_details and payment_errors tables, then have a model for the view (which will be read-only). Some DBs support materialized views, which might be a good idea for performance.

Also consider hardware or VM specs on Rails server and DB server, config, disk space, network speed/latency/etc., proximity, etc. And consider putting DB on different server/VM than the Rails app if you haven't, etc.
