I installed opencv following the steps on https://docs.opencv.org/trunk/d7/d9f/tutorial_linux_install.html

Except on Step 2, use: cmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_GENERATE_PKGCONFIG=YES -D CMAKE_INSTALL_PREFIX=/path/to/opencv/ ..

Then locate the opencv4.pc file, mine was in opencv/build/unix-install/

Now run: $ export PKG_CONFIG_PATH=/path/to/the/file

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

ffmpeg -i sample.avi will give you the audio/video format info for your file. Make sure you have the proper libraries configured to parse the input streams. Also, make sure that the file isn't corrupt.

I had to purge my ffmpeg and then install another one from a ppa:

sudo apt-get purge ffmpeg
sudo apt-add-repository -y ppa:jon-severinsson/ffmpeg 
sudo apt-get update 
sudo apt-get install ffmpeg

Then convert:

 ffmpeg -i audio.ogg -f mp3 newfile.mp3

Switch statements can often be replaced by a good OO design.

For example, you have an Account class, and are using a switch statement to perform a different calculation based on the type of account.

I would suggest that this should be replaced by a number of account classes, representing the different types of account, and all implementing an Account interface.

The switch then becomes unnecessary, as you can treat all types of accounts the same and thanks to polymorphism, the appropriate calculation will be run for the account type.

This answer is for those of you looking to Install Bootstrap 3 in your Rails app without using a gem. There are two simple ways to do this that take less than 10 minutes. Pick the one that suites your needs best. Glyphicons and Javascript work and I've tested them with the latest beta of Rails 4.1.0 as well.

1. Using Bootstrap 3 with Rails 4 - The Bootstrap 3 files are copied into the vendor directory of your application.

2. Adding Bootstrap from a CDN to your Rails application - The Bootstrap 3 files are served from the Bootstrap CDN.

Number 2 above is the most flexible. All you need to do is change the version number that is stored in a layout helper. So you can run the Bootstrap version of your choice, whether that is 3.0.0, 3.0.3 or even older Bootstrap 2 releases.

Wrap each ajax call in a named function and just add them to the success callbacks of the previous call:

function callA() {
    $.ajax({
    ...
    success: function() {
      //do stuff
      callB();
    }
    });
}

function callB() {
    $.ajax({
    ...
    success: function() {
        //do stuff
        callC();
    }
    });
}

function callC() {
    $.ajax({
    ...
    });
}


callA();

Just adding another way of doing this (using Angular) if you don't wanna dirt the HTML with even more code:

You only have to subscribe to the field valueChanges and set the Value as an absolute value (taking care of not emitting a new event because that will cause another valueChange hence a recursive call and trigger a Maximum call size exceeded error)

HTML CODE

<form [formGroup]="myForm">
    <input type="number" formControlName="myInput"/>
</form>

TypeScript CODE (Inside your Component)

formGroup: FormGroup;

ngOnInit() { 
    this.myInput.valueChanges 
    .subscribe(() => {
        this.myInput.setValue(Math.abs(this.myInput.value), {emitEvent: false});
    });
}

get myInput(): AbstractControl {
    return this.myForm.controls['myInput'];
}

Or alternatively, you could use this:

WHERE CHARINDEX(N'Apples', someColumn) = 0

Not sure which one performs better - you gotta test it! :-)

Marc

UPDATE: the performance seems to be pretty much on a par with the other solution (WHERE someColumn NOT LIKE '%Apples%') - so it's really just a question of your personal preference.

The answer of delfuego is the simplest way to solve the certificate problem. But, in my case, one of our third party url (using https), updated their certificate every 2 months automatically. It means that I have to import the cert to our Java trust store manually every 2 months as well. Sometimes it caused production problems.

So, I made a method to solve it with SecureRestClientTrustManager to be able to consume https url without importing the cert file. Here is the method:

     public static String doPostSecureWithHeader(String url, String body, Map headers)
            throws Exception {
        log.info("start doPostSecureWithHeader " + url + " with param " + body);
        long startTime;
        long endTime;
        startTime = System.currentTimeMillis();
        Client client;
        client = Client.create();
        WebResource webResource;
        webResource = null;
        String output = null;
        try{
            SSLContext sslContext = null;
            SecureRestClientTrustManager secureRestClientTrustManager = new SecureRestClientTrustManager();
            sslContext = SSLContext.getInstance("SSL");
            sslContext
            .init(null,
                    new javax.net.ssl.TrustManager[] { secureRestClientTrustManager },
                    null);
            DefaultClientConfig defaultClientConfig = new DefaultClientConfig();
            defaultClientConfig
            .getProperties()
            .put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
                    new com.sun.jersey.client.urlconnection.HTTPSProperties(
                            getHostnameVerifier(), sslContext));

            client = Client.create(defaultClientConfig);
            webResource = client.resource(url);

            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    webResource.setProperty(entry.getKey(), entry.getValue());
                }
            }
            WebResource.Builder builder = 
                    webResource.accept("application/json");
            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    builder.header(entry.getKey(), entry.getValue());
                }
            }

            ClientResponse response = builder
                    .post(ClientResponse.class, body);
            output = response.getEntity(String.class);
        }
        catch(Exception e){
            log.error(e.getMessage(),e);
            if(e.toString().contains("One or more of query value parameters are null")){
                output="-1";
            }
            if(e.toString().contains("401 Unauthorized")){
                throw e;
            }
        }
        finally {
            if (client!= null) {
                client.destroy();
            }
        }
        endTime = System.currentTimeMillis();
        log.info("time hit "+ url +" selama "+ (endTime - startTime) + " milliseconds dengan output = "+output);
        return output;
    }

at and operator[] both return a reference to the indexed element, so you can simply use:

l.at(4) = -1;

or

l[4] = -1;

It is quite simple because you are using the FXMLBuilder.

Just follow these simple steps:

1. Open FXML file into FXMLBuilder.
2. Select the stack pane.
3. Open the Layout tab [left side tab of FXMLBuilder].
4. Set the sides value by which you want to compute the pane size during stage resize like TOP, LEFT, RIGHT, BOTTOM.

Just a helpful hint, there is a company called Yodlee.com who provides this data. They do charge for the API. Companies like Mint.com use this API to gather bank and financial account data.

Also, checkout https://plaid.com/, they are a similar company Yodlee.com and provide both authentication API for several banks and REST-based transaction fetching endpoints.

To activate virtualenv in env directory and export envinroment variables stored in .env use :

source env/bin/activate && set -a; source .env; set +a

To retrieve the position relative to the page efficiently, and without using a recursive function: (includes IE also)

var element = document.getElementById('elementId'); //replace elementId with your element's Id.
var rect = element.getBoundingClientRect();
var elementLeft,elementTop; //x and y
var scrollTop = document.documentElement.scrollTop?
                document.documentElement.scrollTop:document.body.scrollTop;
var scrollLeft = document.documentElement.scrollLeft?                   
                 document.documentElement.scrollLeft:document.body.scrollLeft;
elementTop = rect.top+scrollTop;
elementLeft = rect.left+scrollLeft;

Write the table name in the query editor select the name and press Alt+F1 and it will bring all the information of the table.

If you want to keep a small code base, and you are only going to be needing the toggle button for a small part of the application. I would suggest instead maintain you're javascript code your self (angularjs, javascript, jquery) and just use plain CSS.

Good toggle button generator: https://proto.io/freebies/onoff/

You need one project per language. I'm quite confident I saw a tool that merged assemblies, if you find that tool you should be good to go. If you need to use both languages in the same class, you should be able to write half of it in say VB.net and then write the rest in C# by inheriting the VB.net class.

Currently, Macports has many more packages (~18.6 K) than there are Homebrew formulae (~3.1K), owing to its maturity. Homebrew is slowly catching up though.

Macport packages tend to be maintained by a single person.

Macports can keep multiple versions of packages around, and you can enable or disable them to test things out. Sometimes this list can get corrupted and you have to manually edit it to get things back in order, although this is not too hard.

Both package managers will ask to be regularly updated. This can take some time.

Note: you can have both package managers on your system! It is not one or the other. Brew might complain but Macports won't.

Also, if you are dealing with python or ruby packages, use a virtual environment wherever possible.

Objects does not support push property, but you can save it as well using the index as key,

var tempData = {};_x000D_
for ( var index in data ) {_x000D_
  if ( data[index].Status == "Valid" ) { _x000D_
    tempData[index] = data; _x000D_
  } _x000D_
 }_x000D_
data = tempData;

I think this is easier if remove the object if its status is invalid, by doing.

for(var index in data){_x000D_
  if(data[index].Status == "Invalid"){ _x000D_
    delete data[index]; _x000D_
  } _x000D_
}

And finally you don't need to create a var temp –

in this code data is a two dimensional array of table data

let oTable = document.getElementById('datatable-id');
let data = [...oTable.rows].map(t => [...t.children].map(u => u.innerText))

This is awesome: http://www.ianmccullough.net/5-column-bootstrap-layout/

Just do:

<div class="col-xs-2 col-xs-15">

And CSS:

.col-xs-15{
    width:20%;
}

Something like this:

var objects = [
  {
    "foo" : "bar",
    "bar" : "sit"
  },
  {
    "foo" : "lorem",
    "bar" : "ipsum"
  },
  {
    "foo" : "dolor",
    "bar" : "amet"
  }
];

var results = [];

var toSearch = "lo";

for(var i=0; i<objects.length; i++) {
  for(key in objects[i]) {
    if(objects[i][key].indexOf(toSearch)!=-1) {
      results.push(objects[i]);
    }
  }
}

The results array will contain all matched objects.

If you search for 'lo', the result will be like:

[{ foo="lorem", bar="ipsum"}, { foo="dolor", bar="amet"}]

NEW VERSION - Added trim code, code to ensure no duplicates in result set.

function trimString(s) {
  var l=0, r=s.length -1;
  while(l < s.length && s[l] == ' ') l++;
  while(r > l && s[r] == ' ') r-=1;
  return s.substring(l, r+1);
}

function compareObjects(o1, o2) {
  var k = '';
  for(k in o1) if(o1[k] != o2[k]) return false;
  for(k in o2) if(o1[k] != o2[k]) return false;
  return true;
}

function itemExists(haystack, needle) {
  for(var i=0; i<haystack.length; i++) if(compareObjects(haystack[i], needle)) return true;
  return false;
}

var objects = [
  {
    "foo" : "bar",
    "bar" : "sit"
  },
  {
    "foo" : "lorem",
    "bar" : "ipsum"
  },
  {
    "foo" : "dolor blor",
    "bar" : "amet blo"
  }
];

function searchFor(toSearch) {
  var results = [];
  toSearch = trimString(toSearch); // trim it
  for(var i=0; i<objects.length; i++) {
    for(var key in objects[i]) {
      if(objects[i][key].indexOf(toSearch)!=-1) {
        if(!itemExists(results, objects[i])) results.push(objects[i]);
      }
    }
  }
  return results;
}

console.log(searchFor('lo '));

A solution is to use background-position to mimic the gradient transition. This solution was used in Twitter Bootstrap a few months ago.

Update

http://codersblock.blogspot.fr/2013/12/gradient-animation-trick.html?showComment=1390287622614

Here is a quick example:

Link state

 .btn {
  font-family: "Helvetica Neue", Arial, sans-serif;
  font-size: 12px;
  font-weight: 300;
  position: relative;
  display: inline-block;
  text-decoration: none;
  color: #fff;
  padding: 20px 40px;
  background-image: -moz-linear-gradient(top, #50abdf, #1f78aa);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#50abdf), to(#1f78aa));
  background-image: -webkit-linear-gradient(top, #50abdf, #1f78aa);
  background-image: -o-linear-gradient(top, #50abdf, #1f78aa);
  background-image: linear-gradient(to bottom, #50abdf, #1f78aa);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ff50abdf', endColorstr='#ff1f78aa', GradientType=0);
  background-repeat: repeat-y;
  background-size: 100% 90px;
  background-position: 0 -30px;
  -webkit-transition: all 0.2s linear;
     -moz-transition: all 0.2s linear;
       -o-transition: all 0.2s linear;
          transition: all 0.2s linear;
}

Hover state

.btn:hover {
   background-position: 0 0;
}

Using label for= in html form

This could permit to visualy dissociate label(s) and object while keeping them linked.

Sample: there is a checkbox and two labels. You could check/uncheck the box by clicking indifferently on any label or on box, but not on text nor on input content...

<label for="demo1"> There is a label </label>
<br />
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Duis sem velit, ultrices et, fermentum auctor, rhoncus ut, ligula. Phasellus at purus sed purus cursus iaculis. Suspendisse fermentum. Pellentesque et arcu. Maecenas viverra. In consectetuer, lorem eu lobortis egestas, velit odio imperdiet eros, sit amet sagittis nunc mi ac neque. Sed non ipsum. Nullam venenatis gravida orci.
<br />
<label for="demo1"> There is a 2nd label </label>
<input id="demo1" type="checkbox">Demo 1</input>

Some useful tricks

By use stylesheet CSS power, you could do a lot of interresting things...

#demo2:checked ~ .but2:before { content: 'Des'; }
#demo2:checked ~ .box2:before { content: '?'; }
.but2:before { content: 'S'; }
.box2:before { content: '?'; }
#demo1:checked ~ .but1:before { content: 'Des'; }
#demo1:checked ~ .box1:before { content: '?'; }
.but1:before { content: 'S'; }
.box1:before { content: '?'; }

<input id="demo1" type="checkbox">Demo 1</input>
<input id="demo2" type="checkbox">Demo 2</input>
<br />
<label for="demo1" class="but1">elect 2</label> - 
<label for="demo2" class="but2">elect 1</label>
<br />
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Duis sem velit, ultrices et, fermentum auctor, rhoncus ut, ligula. Phasellus at purus sed purus cursus iaculis. Suspendisse fermentum. Pellentesque et arcu. Maecenas viverra. In consectetuer, lorem eu lobortis egestas, velit odio imperdiet eros, sit amet sagittis nunc mi ac neque. Sed non ipsum. Nullam venenatis gravida orci.
<br />
<label for="demo1" class="but1">elect this 2nd label </label> - 
<label class="but2" for="demo2">elect this another 2nd label </label>
<br />
<label for="demo1" class="box1"> check 1</label>
<label for="demo2" class="box2"> check 2</label> 

I like the answer of Anacrust, though, by the fact "console.log" is executed twice, I would like to do a small update for src/mylib.js:

let test = {
  foo () { return 'foo' },
  bar () { return 'bar' },
  baz () { return 'baz' }
}

export default test

All other code remains the same...

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

1. Open Vs Code
2. Go to view
3. Click on terminal to open a terminal in VS Code
4. Copy the link for your existing repository from your GitHub page.
5. Type “git clone” and paste the link in addition i.e “git clone https://github.com/...”
6. This will open the repository in your Vs Code Editor.

You don't have to force yourself to remember differences between them. Think of how you actually made a commit.

1. Make some changes.

2. git add .

3. git commit -m "I did Something"

Soft, Mixed and Hard is the way enabling you to give up the operations you did from 3 to 1.

• Soft "pretended" to never see you have did git commit.
• Mixed "pretended" to never see you have did git add .
• Hard "pretended" to never see you have made file changes.

The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.

The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.

The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.

Edit: Also worth a look - kashif's comment about json-streamer and Henrik Heino's comment about bigjson.

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

If you just want to apply a function to each element and put the results in an output array, you can use arrayfun.

As others have pointed out, for most operations, it's best to avoid loops in MATLAB and vectorise your code instead.

FYI, it looks like the syntax for retrieving the values has changed according to:

http://freemarker.sourceforge.net/docs/ref_builtins_hash.html

<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>

Go to the project's properties page, select the "Web" tab and on top (in the "Start Action" section), enter the page name in the "Specific Page" box. In your case index.aspx

You don't need jQuery to do this. Here's an ES2015 solution:

// Get all input fields
const inputs = document.querySelectorAll('#register input');

// Get only the required ones
const requiredFields = Array.from(inputs).filter(input => input.required);

// Do your stuff with the required fields
requiredFields.forEach(field => /* do what you want */);

Or you could just use the :required selector:

Array.from(document.querySelectorAll('#register input:required'))
    .forEach(field => /* do what you want */);

Update August 2019

In Android Studio 3.5 Instant Run was replaced with Apply Changes. And it works in different way: APK is not modified on the fly anymore but instead runtime instrumentation is used to redefine classes on the fly (more info). So since Android Studio 3.5 instant run settings are replaced with Deployment (Settings -> Build, Execution, Deployment -> Deployment):

Here is a short cheatsheet that covers typical cases:

// sort
list.sort(naturalOrder())

// sort (reversed)
list.sort(reverseOrder())

// sort by field
list.sort(comparing(Type::getField))

// sort by field (reversed)
list.sort(comparing(Type::getField).reversed())

// sort by int field
list.sort(comparingInt(Type::getIntField))

// sort by double field (reversed)
list.sort(comparingDouble(Type::getDoubleField).reversed())

// sort by nullable field (nulls last)
list.sort(comparing(Type::getNullableField, nullsLast(naturalOrder())))

// two-level sort
list.sort(comparing(Type::getField1).thenComparing(Type::getField2))

To delete a module in Android Studio 2.3.3,

• Open File -> Project Structure
• On Project Structure window, list of modules of the current project gets displayed on left panel. Select the module which needs to be deleted.
• Then click - button on top left, that means just above left panel.

NSString* path  = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"json"];

//????????????,????NSUTF8StringEncoding ????,
NSString* jsonString = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

//??????????
NSData* jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

NSError *jsonError;
id allKeys = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONWritingPrettyPrinted error:&jsonError];


for (int i=0; i<[allKeys count]; i++) {
    NSDictionary *arrayResult = [allKeys objectAtIndex:i];
    NSLog(@"name=%@",[arrayResult objectForKey:@"storyboardName"]);

}

file:

 [
  {
  "ID":1,
  "idSort" : 0,
  "deleted":0,
  "storyboardName" : "MLMember",
  "dispalyTitle" : "76.360779",
  "rightLevel" : "10.010490",
  "showTabBar" : 1,
  "openWeb" : 0,
  "webUrl":""
  },
  {
  "ID":1,
  "idSort" : 0,
  "deleted":0,
  "storyboardName" : "0.00",
  "dispalyTitle" : "76.360779",
  "rightLevel" : "10.010490",
  "showTabBar" : 1,
  "openWeb" : 0,
  "webUrl":""
  }
  ]

To detect your controller is pushed or not just use below code in anywhere you want:

if ([[[self.parentViewController childViewControllers] firstObject] isKindOfClass:[self class]]) {

    // Not pushed
}
else {

    // Pushed
}

I hope this code can help anyone...

Another solution w/AES-256 support: https://github.com/digitalbazaar/forge

Just use the Class method using this foobar->foobarfunc();

Kotlin Extension Properties

No file will be create when you make a File object, it is only an interface.

To make working with files easier, there is an existing .toFile function on Uri

You can also add an extension property on File and/or Uri, to simplify usage further.

val File?.exists get() = this?.exists() ?: false
val Uri?.exists get() = File(this.toString).exists()

Then just use uri.exists or file.exists to check.

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

Try this:

$('#listItem').not($('#listItem').children()).text()

you want

import os
os.getcwd()
os.chdir('..')

HTML5 basically behaves as if the trailing slash is not there. There is no such thing as a self-closing tag in HTML5 syntax.

• Self-closing tags on non-void elements like <p/>, <div/> will not work at all. The trailing slash will be ignored, and these will be treated as opening tags. This is likely to lead to nesting problems.

  This is true regardless of whether there is whitespace in front of the slash: <p /> and <div /> also won't work for the same reason.

• Self-closing tags on void elements like <br/> or <img src="" alt=""/> will work, but only because the trailing slash is ignored, and in this case that happens to result in the correct behaviour.

The result is, anything that worked in your old "XHTML 1.0 served as text/html" will continue to work as it did before: trailing slashes on non-void tags were not accepted there either whereas the trailing slash on void elements worked.

One more note: it is possible to represent an HTML5 document as XML, and this is sometimes dubbed "XHTML 5.0". In this case the rules of XML apply and self-closing tags will always be handled. It would always need to be served with an XML mime type.

Like you said since the xpath for the next button is the same on every page it won't work. It's working as coded in that it does wait for the element to be displayed but since it's already displayed then the implicit wait doesn't apply because it doesn't need to wait at all. Why don't you use the fact that the url changes since from your code it appears to change when the next button is clicked. I do C# but I guess in Java it would be something like:

WebDriver driver = new FirefoxDriver();
String startURL = //a starting url;
String currentURL = null;
WebDriverWait wait = new WebDriverWait(driver, 10);

foo(driver,startURL);

/* go to next page */
if(driver.findElement(By.xpath("//*[@id='someID']")).isDisplayed()){
    String previousURL = driver.getCurrentUrl();
    driver.findElement(By.xpath("//*[@id='someID']")).click();  
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    ExpectedCondition e = new ExpectedCondition<Boolean>() {
          public Boolean apply(WebDriver d) {
            return (d.getCurrentUrl() != previousURL);
          }
        };

    wait.until(e);
    currentURL = driver.getCurrentUrl();
    System.out.println(currentURL);
} 

Thank Mathias Lin, tested and it works!

In addition, sample implementation of Mathias's method in activity can be as follows.

public class DirectionMapActivity extends MapActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.directionmap);

        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);

        // Acquire a reference to the system Location Manager
        LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

        String locationProvider = LocationManager.NETWORK_PROVIDER;
        Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);

        StringBuilder urlString = new StringBuilder();
        urlString.append("http://maps.google.com/maps?f=d&hl=en");
        urlString.append("&saddr=");//from
        urlString.append( Double.toString(lastKnownLocation.getLatitude() ));
        urlString.append(",");
        urlString.append( Double.toString(lastKnownLocation.getLongitude() ));
        urlString.append("&daddr=");//to
        urlString.append( Double.toString((double)dest[0]/1.0E6 ));
        urlString.append(",");
        urlString.append( Double.toString((double)dest[1]/1.0E6 ));
        urlString.append("&ie=UTF8&0&om=0&output=kml");

        try{
            // setup the url
            URL url = new URL(urlString.toString());
            // create the factory
            SAXParserFactory factory = SAXParserFactory.newInstance();
            // create a parser
            SAXParser parser = factory.newSAXParser();
            // create the reader (scanner)
            XMLReader xmlreader = parser.getXMLReader();
            // instantiate our handler
            NavigationSaxHandler navSaxHandler = new NavigationSaxHandler();
            // assign our handler
            xmlreader.setContentHandler(navSaxHandler);
            // get our data via the url class
            InputSource is = new InputSource(url.openStream());
            // perform the synchronous parse           
            xmlreader.parse(is);
            // get the results - should be a fully populated RSSFeed instance, or null on error
            NavigationDataSet ds = navSaxHandler.getParsedData();

            // draw path
            drawPath(ds, Color.parseColor("#add331"), mapView );

            // find boundary by using itemized overlay
            GeoPoint destPoint = new GeoPoint(dest[0],dest[1]);
            GeoPoint currentPoint = new GeoPoint( new Double(lastKnownLocation.getLatitude()*1E6).intValue()
                                                ,new Double(lastKnownLocation.getLongitude()*1E6).intValue() );

            // center and zoom in the map
            MapController mc = mapView.getController();
            mc.zoomToSpan(bgItemizedOverlay.getLatSpanE6()*2,bgItemizedOverlay.getLonSpanE6()*2);
            mc.animateTo(new GeoPoint(
                    (currentPoint.getLatitudeE6() + destPoint.getLatitudeE6()) / 2
                    , (currentPoint.getLongitudeE6() + destPoint.getLongitudeE6()) / 2));

        } catch(Exception e) {
            Log.d("DirectionMap","Exception parsing kml.");
        }

    }
    // and the rest of the methods in activity, e.g. drawPath() etc...

Don't forget that unlike Windows, all Unix based system need to have the source before destination unlike Windows

On Windows its:

mov $source , %destination

but on the Mac its the other way around.

Using bit shift is a little quicker...

public static String convertDecimalToBinary(int N) {

    StringBuilder binary = new StringBuilder(32);

    while (N > 0 ) {
        binary.append( N % 2 );
        N >>= 1;
     }

    return binary.reverse().toString();

}

Java Shift Caesar Cipher by shift spaces.

Restrictions:

1. Only works with a positive number in the shift parameter.
2. Only works with shift less than 26.
3. Does a += which will bog the computer down for bodies of text longer than a few thousand characters.
4. Does a cast number to character, so it will fail with anything but ascii letters.
5. Only tolerates letters a through z. Cannot handle spaces, numbers, symbols or unicode.
6. Code violates the DRY (don't repeat yourself) principle by repeating the calculation more than it has to.

Pseudocode:

1. Loop through each character in the string.
2. Add shift to the character and if it falls off the end of the alphabet then subtract shift from the number of letters in the alphabet (26)
3. If the shift does not make the character fall off the end of the alphabet, then add the shift to the character.
4. Append the character onto a new string. Return the string.

Function:

String cipher(String msg, int shift){
    String s = "";
    int len = msg.length();
    for(int x = 0; x < len; x++){
        char c = (char)(msg.charAt(x) + shift);
        if (c > 'z')
            s += (char)(msg.charAt(x) - (26-shift));
        else
            s += (char)(msg.charAt(x) + shift);
    }
    return s;
}

How to invoke it:

System.out.println(cipher("abc", 3));  //prints def
System.out.println(cipher("xyz", 3));  //prints abc

If you want to merge the filters (eg. CSV and Excel files), use this formula:

OpenFileDialog of = new OpenFileDialog();
of.Filter = "CSV files (*.csv)|*.csv|Excel Files|*.xls;*.xlsx";

Or if you want to see XML or PDF files in one time use this:

of.Filter = @" XML or PDF |*.xml;*.pdf";

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

I have a dataset in my app and I went to set changes (deleting a row) to it but ds.tabales["TableName"] is read only. Then I found this solution.

It's a wpf C# app,

try {
    var results = from row in ds.Tables["TableName"].AsEnumerable() where row.Field<string>("Personalid") == "47" select row;                
    foreach (DataRow row in results) {
        ds.Tables["TableName"].Rows.Remove(row);                 
    }           
}

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:

>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
 0.00  1.00  2.00  3.00  4.00
 5.00  6.00  7.00  8.00  9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00

Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).

padding-right should work. Example linked.

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

Since a jQuery object inherits from an array, and this array contains the selected DOM elements. Saying you're using an id and so the element should be unique within the DOM, you could perform a direct call to submit by doing :

$(".nextbutton").click(function() { 
  $("#formID")[0].submit();
});

According to BOL:

Indexed views and indexes on computed columns store results in the database for later reference. The stored results are valid only if all connections referring to the indexed view or indexed computed column can generate the same result set as the connection that created the index.

In order to create a table with a persisted, computed column, the following connection settings must be enabled:

SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
SET ARITHABORT ON
SET CONCAT_NULL_YIELDS_NULL ON
SET NUMERIC_ROUNDABORT ON
SET QUOTED_IDENTIFIER ON

These values are set on the database level and can be viewed using:

SELECT 
    is_ansi_nulls_on,
    is_ansi_padding_on,
    is_ansi_warnings_on,
    is_arithabort_on,
    is_concat_null_yields_null_on,
    is_numeric_roundabort_on,
    is_quoted_identifier_on
FROM sys.databases

However, the SET options can also be set by the client application connecting to SQL Server.

A perfect example is SQL Server Management Studio which has the default values for SET ANSI_NULLS and SET QUOTED_IDENTIFIER both to ON. This is one of the reasons why I could not initially duplicate the error you posted.

Anyway, to duplicate the error, try this (this will override the SSMS default settings):

SET ANSI_NULLS ON
SET ANSI_PADDING OFF
SET ANSI_WARNINGS OFF
SET ARITHABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON 
SET NUMERIC_ROUNDABORT OFF
SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE T1 (
    ID INT NOT NULL,
    TypeVal AS ((1)) PERSISTED NOT NULL
) 

You can fix the test case above by using:

SET ANSI_PADDING ON
SET ANSI_WARNINGS ON

I would recommend tweaking these two settings in your script before the creation of the table and related indexes.

(Latest as of 2020) For version Chrome Version 83.0.4103.61 :

1. Select the element you want to inspect

2. Choose the Event Listeners tab

3. Make sure to check the Framework listeners to show the real javascript file instead of the jquery function.

This maybe not the answer to poster's question.But this may helpful to people whose face same situation with me:

The client have two network cards,a wireless one and a normal one. The ping to server can be succeed.However telnet serverAddress 3306 would fail. And would complain

Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060)

when try to connect to server.So I forbidden the normal network adapters. And tried telnet serverAddress 3306 it works.And then it work when connect to MySQL server.

This worked for me:
chmod 700 .ssh chmod 600 .ssh/id_rsa chmod 644 .ssh/id_rsa.pub

Then, type this: ssh-add ~/.ssh/id_rsa

Let me give some information on them:

1. quit() simply raises the SystemExit exception.

   Furthermore, if you print it, it will give a message:

   >>> print (quit)
   Use quit() or Ctrl-Z plus Return to exit
   >>>
   

   This functionality was included to help people who do not know Python. After all, one of the most likely things a newbie will try to exit Python is typing in quit.

   Nevertheless, quit should not be used in production code. This is because it only works if the site module is loaded. Instead, this function should only be used in the interpreter.

2. exit() is an alias for quit (or vice-versa). They exist together simply to make Python more user-friendly.

   Furthermore, it too gives a message when printed:

   >>> print (exit)
   Use exit() or Ctrl-Z plus Return to exit
   >>>
   

   However, like quit, exit is considered bad to use in production code and should be reserved for use in the interpreter. This is because it too relies on the site module.

3. sys.exit() also raises the SystemExit exception. This means that it is the same as quit and exit in that respect.

   Unlike those two however, sys.exit is considered good to use in production code. This is because the sys module will always be there.

4. os._exit() exits the program without calling cleanup handlers, flushing stdio buffers, etc. Thus, it is not a standard way to exit and should only be used in special cases. The most common of these is in the child process(es) created by os.fork.

   Note that, of the four methods given, only this one is unique in what it does.

Summed up, all four methods exit the program. However, the first two are considered bad to use in production code and the last is a non-standard, dirty way that is only used in special scenarios. So, if you want to exit a program normally, go with the third method: sys.exit.

Or, even better in my opinion, you can just do directly what sys.exit does behind the scenes and run:

raise SystemExit

This way, you do not need to import sys first.

However, this choice is simply one on style and is purely up to you.

There is an open-source javascript plugin that does just that - debugout.js

Debugout.js records and save console.logs so your application can access them. Full disclosure, I wrote it. It formats different types appropriately, can handle nested objects and arrays, and can optionally put a timestamp next to each log. It also toggles live-logging in one place.

I am using this Typescript snippet:

function UInt8ArrayToString(uInt8Array: Uint8Array): string
{
    var s: string = "[";
    for(var i: number = 0; i < uInt8Array.byteLength; i++)
    {
        if( i > 0 )
            s += ", ";
        s += uInt8Array[i];
    }
    s += "]";
    return s;
}

Remove the type annotations if you need the JavaScript version. Hope this helps!

Proxies are supported through two system properties: http.proxyHost and http.proxyPort. They must be set to the proxy server and port respectively. The following basic example illustrates it:

String url = "http://www.google.com/",
       proxy = "proxy.mydomain.com",
       port = "8080";
URL server = new URL(url);
Properties systemProperties = System.getProperties();
systemProperties.setProperty("http.proxyHost",proxy);
systemProperties.setProperty("http.proxyPort",port);
HttpURLConnection connection = (HttpURLConnection)server.openConnection();
connection.connect();
InputStream in = connection.getInputStream();
readResponse(in);

I came across this when facing a similar problem, except I needed to check if a path is for a file or folder when that file or folder may not actually exist. There were a few comments on answers above that mentioned they would not work for this scenario. I found a solution (I use VB.NET, but you can convert if you need) that seems to work well for me:

Dim path As String = "myFakeFolder\ThisDoesNotExist\"
Dim bIsFolder As Boolean = (IO.Path.GetExtension(path) = "")
'returns True

Dim path As String = "myFakeFolder\ThisDoesNotExist\File.jpg"
Dim bIsFolder As Boolean = (IO.Path.GetExtension(path) = "")
'returns False

Hopefully this can be helpful to someone!

If you already know your remote branch like so...

git remote
=> One
=> Two

and you know the branch name you wish to checkout, for example, br1.2.3.4, then do

git fetch One
=> returns all meta data of remote, that is, the branch name in question.

All that is left is to checkout the branch

git checkout br.1.2.3.4

Then make any new branches off of it.

Are the classes imported? Try pressing CTRL + SHIFT + O to resolve the imports. If this does not work you need to include the application servers runtime libraries.

1. Windows > Preferences
2. Server > Runtime Environment
3. Add
4. Select your appropriate environment, click Next
5. Point to the install directory and click Finish.

List indexes of -x mean the xth item from the end of the list, so n[-1] means the last item in the list n. Any good Python tutorial should have told you this.

It's an unusual convention that only a few other languages besides Python have adopted, but it is extraordinarily useful; in any other language you'll spend a lot of time writing n[n.length-1] to access the last item of a list.

You need to use jackson-module-kotlin to deserialize to data classes. See here for details.

The error message above is what Jackson gives you if you try to deserialize some value into a data class when that module isn't enabled or, even if it is, when the ObjectMapper it uses doesn't have the KotlinModule registered. For example, take this code:

data class TestDataClass (val foo: String)

val jsonString = """{ "foo": "bar" }"""
val deserializedValue = ObjectMapper().readerFor(TestDataClass::class.java).readValue<TestDataClass>(jsonString)

This will fail with the following error:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `test.SerializationTests$TestDataClass` (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)

If you change the code above and replace ObjectMapper with jacksonObjectMapper (which simply returns a normal ObjectMapper with the KotlinModule registered), it works. i.e.

val deserializedValue = jacksonObjectMapper().readerFor(TestDataClass::class.java).readValue<TestDataClass>(jsonString)

I'm not sure about the Android side of things, but it looks like you'll need to get the system to use the jacksonObjectMapper to do the deserialization.

You can use a timedelta object:

from datetime import datetime, timedelta
    
d = datetime.today() - timedelta(days=days_to_subtract)

This works for me!

<label for="reason">Reason:</label>
<select name="reason" size="1" id="name" >
    <option value="NG" selected="SELECTED"><?php if (!(strcmp("NG", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>Selection a reason below</option>
    <option value="General"<?php if (!(strcmp("General", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>General Question</option>
    <option value="Account"<?php if (!(strcmp("Account", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Account Question</option>
    <option value="Other"<?php if (!(strcmp("Other", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Other</option>

</select>

You can call a stored procedure from another stored procedure by using the EXECUTE command.

Say your procedure is X. Then in X you can use

EXECUTE PROCEDURE Y () RETURNING_VALUES RESULT;"

Another possible solution that works for me is something like -

cat a.txt | xargs bash -c 'command1 $@; command2 $@' bash

Note the 'bash' at the end - I assume it is passed as argv[0] to bash. Without it in this syntax the first parameter to each command is lost. It may be any word.

Example:

cat a.txt | xargs -n 5 bash -c 'echo -n `date +%Y%m%d-%H%M%S:` ; echo " data: " $@; echo "data again: " $@' bash

Inspired by many other FFmpeg on Android implementations out there (mainly the guadianproject), I found a solution (with Lame support also).

(lame and FFmpeg: https://github.com/intervigilium/liblame and http://bambuser.com/opensource)

to call FFmpeg:

new Thread(new Runnable() {

    @Override
    public void run() {

        Looper.prepare();

        FfmpegController ffmpeg = null;

        try {
            ffmpeg = new FfmpegController(context);
        } catch (IOException ioe) {
            Log.e(DEBUG_TAG, "Error loading ffmpeg. " + ioe.getMessage());
        }

        ShellDummy shell = new ShellDummy();
        String mp3BitRate = "192";

        try {
            ffmpeg.extractAudio(in, out, audio, mp3BitRate, shell);
        } catch (IOException e) {
            Log.e(DEBUG_TAG, "IOException running ffmpeg" + e.getMessage());
        } catch (InterruptedException e) {
            Log.e(DEBUG_TAG, "InterruptedException running ffmpeg" + e.getMessage());
        }

        Looper.loop();

    }

}).start();

and to handle the console output:

private class ShellDummy implements ShellCallback {

    @Override
    public void shellOut(String shellLine) {
        if (someCondition) {
            doSomething(shellLine);
        }
        Utils.logger("d", shellLine, DEBUG_TAG);
    }

    @Override
    public void processComplete(int exitValue) {
        if (exitValue == 0) {
            // Audio job OK, do your stuff: 

                            // i.e.             
                            // write id3 tags,
                            // calls the media scanner,
                            // etc.
        }
    }

    @Override
    public void processNotStartedCheck(boolean started) {
        if (!started) {
                            // Audio job error, as above.
        }
    }
}

Bouncy Castle still requires jars installed as far as I can tell.

I did a little test and it seemed to confirm this:

http://www.bouncycastle.org/wiki/display/JA1/Frequently+Asked+Questions

This assumes that the content is in column B on each sheet (since it's not clear how you determine the column on each sheet.) and the last row of that column is also the last row of the sheet.

$xlCellTypeLastCell = 11 
$startRow = 5 
$col = 2 

$excel = New-Object -Com Excel.Application
$wb = $excel.Workbooks.Open("C:\Users\Administrator\my_test.xls")

for ($i = 1; $i -le $wb.Sheets.Count; $i++)
{
    $sh = $wb.Sheets.Item($i)
    $endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
    $city = $sh.Cells.Item($startRow, $col).Value2
    $rangeAddress = $sh.Cells.Item($startRow + 1, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
    $sh.Range($rangeAddress).Value2 | foreach 
    {
        New-Object PSObject -Property @{ City = $city; Area = $_ }
    }
}

$excel.Workbooks.Close()

You're not passing any credentials to sqlcmd.exe

So it's trying to authenticate you using the Windows Login credentials, but you mustn't have your SQL Server setup to accept those credentials...

When you were installing it, you would have had to supply a Server Admin password (for the sa account)

Try...

sqlcmd.exe -U sa -P YOUR_PASSWORD -S ".\SQL2008"

for reference, theres more details here...

It turns out that the solution is to stop all the related services and solve the “Another daemon is already running” issue.

The commands i used to solve the issue are as follows:

sudo /opt/lampp/lampp stop              
sudo /etc/init.d/apache2 stop    
sudo /etc/init.d/mysql stop

Or, you can also type instead:

sudo service apache2 stop
sudo service mysql stop

After that, we again start the lampp services:

sudo /opt/lampp/lampp start

Now, there must be no problems while opening:

http://localhost                  
http://localhost/phpmyadmin

I suggest sty. It's similar to colorama, but less verbose and it supports 8bit and 24bit colors. You can also extend the color register with your own colors.

Examples:

from sty import fg, bg, ef, rs

foo = fg.red + 'This is red text!' + fg.rs
bar = bg.blue + 'This has a blue background!' + bg.rs
baz = ef.italic + 'This is italic text' + rs.italic
qux = fg(201) + 'This is pink text using 8bit colors' + fg.rs
qui = fg(255, 10, 10) + 'This is red text using 24bit colors.' + fg.rs

# Add custom colors:

from sty import Style, RgbFg

fg.orange = Style(RgbFg(255, 150, 50))

buf = fg.orange + 'Yay, Im orange.' + fg.rs

print(foo, bar, baz, qux, qui, buf, sep='\n')

Demo:

Here is another way to accomplish this in less code.

UPDATE 3: Asynchronous model class statics

Similar to option 2, this allows you to create a function directly linked to the schema, but called from the same file using the model.

model.js

 userSchema.statics.updateUser = function(user, cb) {
  UserModel.find({name : user.name}).exec(function(err, docs) {
    if (docs.length){
      cb('Name exists already', null);
    } else {
      user.save(function(err) {
        cb(err,user);
      }
    }
  });
}

Call from file

var User = require('./path/to/model');

User.updateUser(user.name, function(err, user) {
  if(err) {
    var error = new Error('Already exists!');
    error.status = 401;
    return next(error);
  }
});

A simple solution for Groovy:

solutionArray.sort{ new Random().nextInt() }

This will sort all elements of the array list randomly which archives the desired result of shuffling all elements.

As stated by drewmoore, the proper solution in this case is to manually trigger change detection for the current component. This is done using the detectChanges() method of the ChangeDetectorRef object (imported from angular2/core), or its markForCheck() method, which also makes any parent components update. Relevant example:

import { Component, ChangeDetectorRef, AfterViewInit } from 'angular2/core'

@Component({
  selector: 'my-app',
  template: `<div>I'm {{message}} </div>`,
})
export class App implements AfterViewInit {
  message: string = 'loading :(';

  constructor(private cdr: ChangeDetectorRef) {}

  ngAfterViewInit() {
    this.message = 'all done loading :)'
    this.cdr.detectChanges();
  }

}

Here are also Plunkers demonstrating the ngOnInit, setTimeout, and enableProdMode approaches just in case.

set the bg after loading the html(from quick tests it seems loading the html resets the bg color.. this is for 2.3).

if you're loading the html from data you already got, just doing a .postDelayed in which you just set the bg(to for example transparent) is enough..

You can connect one computer to another computer in a network by using these two methods:

• Use WMI library.
• Netuse method.

WMI

Here is the example to connect using wmi module:

ip = '192.168.1.13'
username = 'username'
password = 'password'
from socket import *
try:
    print("Establishing connection to %s" %ip)
    connection = wmi.WMI(ip, user=username, password=password)
    print("Connection established")
except wmi.x_wmi:
    print("Your Username and Password of "+getfqdn(ip)+" are wrong.")

netuse

The second method is to use netuse module.

By Netuse, you can connect to remote computer. And you can access all data of the remote computer. It is possible in the following two ways:

1. Connect by virtual connection.

   import win32api
   import win32net
   ip = '192.168.1.18'
   username = 'ram'
   password = 'ram@123'
   
   use_dict={}
   use_dict['remote']=unicode('\\\\192.168.1.18\C$')
   use_dict['password']=unicode(password)
   use_dict['username']=unicode(username)
   win32net.NetUseAdd(None, 2, use_dict)
   

   To disconnect:

   import win32api
   import win32net
   win32net.NetUseDel('\\\\192.168.1.18',username,win32net.USE_FORCE)
   

2. Mount remote computer drive in local system.

   import win32api
   import win32net
   import win32netcon,win32wnet
   
   username='user'
   password='psw'
   
   try:
       win32wnet.WNetAddConnection2(win32netcon.RESOURCETYPE_DISK, 'Z:','\\\\192.168.1.18\\D$', None, username, password, 0)
       print('connection established successfully')
   except:
       print('connection not established')
   

   To unmount remote computer drive in local system:

   import win32api
   import win32net
   import win32netcon,win32wnet
   
   win32wnet.WNetCancelConnection2('\\\\192.168.1.4\\D$',1,1)
   

Before using netuse you should have pywin32 install in your system with python also.

I believe IsEmpty is just method that takes return value of Cell and checks if its Empty so: IsEmpty(.Cell(i,1)) does ->

return .Cell(i,1) <> Empty

Use CurrPorts (it's free and no-install): http://www.nirsoft.net/utils/cports.html

/close <Local Address> <Local Port> <Remote Address> <Remote Port> {Process Name}

Examples:

# Close all connections with remote port 80 and remote address 192.168.1.10: 
/close * * 192.168.1.10 80
# Close all connections with remote port 80 (for all remote addresses): 
/close * * * 80
# Close all connections to remote address 192.168.20.30: 
/close * * 192.168.20.30 *
# Close all connections with local port 80: 
/close * 80 * *
# Close all connections of Firefox with remote port 80: 
/close * * * 80 firefox.exe

It also has a nice GUI with search and filter features.

Note: This answer is huntharo and JasonXA's answer and comment put together and simplified to make it easier for readers. Examples come from CurrPorts' web page.

Taken from the Android sources here. This is the actual code that shows your MAC ADDRESS in the system's settings app.

private void refreshWifiInfo() {
    WifiInfo wifiInfo = mWifiManager.getConnectionInfo();

    Preference wifiMacAddressPref = findPreference(KEY_MAC_ADDRESS);
    String macAddress = wifiInfo == null ? null : wifiInfo.getMacAddress();
    wifiMacAddressPref.setSummary(!TextUtils.isEmpty(macAddress) ? macAddress
            : getActivity().getString(R.string.status_unavailable));

    Preference wifiIpAddressPref = findPreference(KEY_CURRENT_IP_ADDRESS);
    String ipAddress = Utils.getWifiIpAddresses(getActivity());
    wifiIpAddressPref.setSummary(ipAddress == null ?
            getActivity().getString(R.string.status_unavailable) : ipAddress);
}

Take a look at cat /proc/stat

grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

EDIT please read comments before copy-paste this or using this for any serious work. This was not tested nor used, it's an idea for people who do not want to install a utility or for something that works in any distribution. Some people think you can "apt-get install" anything.

NOTE: this is not the current CPU usage, but the overall CPU usage in all the cores since the system bootup. This could be very different from the current CPU usage. To get the current value top (or similar tool) must be used.

Current CPU usage can be potentially calculated with:

awk '{u=$2+$4; t=$2+$4+$5; if (NR==1){u1=u; t1=t;} else print ($2+$4-u1) * 100 / (t-t1) "%"; }' \
<(grep 'cpu ' /proc/stat) <(sleep 1;grep 'cpu ' /proc/stat)

The efficient way to do that is just to cast to a generic Map as follows:

Properties props = new Properties();

Map<String, String> map = (Map)props;

This will convert a Map<Object, Object> to a raw Map, which is "ok" for the compiler (only warning). Once we have a raw Map it will cast to Map<String, String> which it also will be "ok" (another warning). You can ignore them with annotation @SuppressWarnings({ "unchecked", "rawtypes" })

This will work because in the JVM the object doesn't really have a generic type. Generic types are just a trick that verifies things at compile time.

If some key or value is not a String it will produce a ClassCastException error. With current Properties implementation this is very unlikely to happen, as long as you don't use the mutable call methods from the super Hashtable<Object,Object> of Properties.

So, if don't do nasty things with your Properties instance this is the way to go.

1. No, unfortunately.
2. You just can't in the way you want, as it's not allowed by the grammar (more below). You can only use ctor-like initialization, and, as you know, that's not available for initializing each item in arrays.
3. I believe so, as they generalize initialization across the board in many useful ways. But I'm not sure on the details.

In C++03, aggregate initialization only applies with syntax similar as below, which must be a separate statement and doesn't fit in a ctor initializer.

T var = {...};

UPD Today I avoid Docker Swarm, secrets, and configs. I'd run it with docker-compose and the .env file. As long as I don't need autoscaling. If I do, I'd probably choose k8s. And database passwords, root account or not... Do they really matter when you're running a single database in a container not connected to the outside world?.. I'd like to know what you think about it, but Stack Overflow is probably not well suited for this sort of communication.

Mongo image can be affected by MONGO_INITDB_DATABASE variable, but it won't create the database. This variable determines current database when running /docker-entrypoint-initdb.d/* scripts. Since you can't use environment variables in scripts executed by Mongo, I went with a shell script:

docker-swarm.yml:

version: '3.1'

secrets:
  mongo-root-passwd:
    file: mongo-root-passwd
  mongo-user-passwd:
    file: mongo-user-passwd

services:
  mongo:
    image: mongo:3.2
    environment:
      MONGO_INITDB_ROOT_USERNAME: $MONGO_ROOT_USER
      MONGO_INITDB_ROOT_PASSWORD_FILE: /run/secrets/mongo-root-passwd
      MONGO_INITDB_USERNAME: $MONGO_USER
      MONGO_INITDB_PASSWORD_FILE: /run/secrets/mongo-user-passwd
      MONGO_INITDB_DATABASE: $MONGO_DB
    volumes:
      - ./init-mongo.sh:/docker-entrypoint-initdb.d/init-mongo.sh
    secrets:
      - mongo-root-passwd
      - mongo-user-passwd

init-mongo.sh:

mongo -- "$MONGO_INITDB_DATABASE" <<EOF
    var rootUser = '$MONGO_INITDB_ROOT_USERNAME';
    var rootPassword = '$MONGO_INITDB_ROOT_PASSWORD';
    var admin = db.getSiblingDB('admin');
    admin.auth(rootUser, rootPassword);

    var user = '$MONGO_INITDB_USERNAME';
    var passwd = '$(cat "$MONGO_INITDB_PASSWORD_FILE")';
    db.createUser({user: user, pwd: passwd, roles: ["readWrite"]});
EOF

Alternatively, you can store init-mongo.sh in configs (docker config create) and mount it with:

configs:
    init-mongo.sh:
        external: true
...
services:
    mongo:
        ...
        configs:
            - source: init-mongo.sh
              target: /docker-entrypoint-initdb.d/init-mongo.sh

And secrets can be not stored in a file.

A couple of gists on the matter.

Polymorphism is a multiple implementations of an object or you could say multiple forms of an object. lets say you have class Animals as the abstract base class and it has a method called movement() which defines the way that the animal moves. Now in reality we have different kinds of animals and they move differently as well some of them with 2 legs, others with 4 and some with no legs, etc.. To define different movement() of each animal on earth, we need to apply polymorphism. However, you need to define more classes i.e. class Dogs Cats Fish etc. Then you need to extend those classes from the base class Animals and override its method movement() with a new movement functionality based on each animal you have. You can also use Interfaces to achieve that. The keyword in here is overriding, overloading is different and is not considered as polymorphism. with overloading you can define multiple methods "with same name" but with different parameters on same object or class.

Visit https://www.arduino.cc/en/Reference/StringConstructor to solve the problem easily.

This worked for me:

char yyy[6];

String xxx;

yyy[0]='h';

yyy[1]='e';

yyy[2]='l';

yyy[3]='l';

yyy[4]='o';

yyy[5]='\0';

xxx=String(yyy);

after creating the view we have to add layout parameters .

change like this

TextView tv = new TextView(this);
tv.setLayoutParams(new ViewGroup.LayoutParams(
        ViewGroup.LayoutParams.WRAP_CONTENT,
        ViewGroup.LayoutParams.WRAP_CONTENT));

llview.addView(tv);
tv.setTextColor(Color.WHITE);
tv.setTextSize(2,25);
tv.setText(chat);
if (mine) {
    leftMargin = 5;
    tv.setBackgroundColor(0x7C5B77);
}
else {
    leftMargin = 50;
    tv.setBackgroundColor(0x778F6E);
}
final ViewGroup.MarginLayoutParams lpt =(MarginLayoutParams)tv.getLayoutParams();
lpt.setMargins(leftMargin,lpt.topMargin,lpt.rightMargin,lpt.bottomMargin);

The advantages of an abstract class are:

• Ability to specify default implementations of methods
• Added invariant checking to functions
• Have slightly more control in how the "interface" methods are called
• Ability to provide behavior related or unrelated to the interface for "free"

Interfaces are merely data passing contracts and do not have these features. However, they are typically more flexible as a type can only be derived from one class, but can implement any number of interfaces.

Just my 2 cents. I would create a solution which records exactly what changed, very similar to transient's solution.

My ChangesTable would simple be:

DateTime | WhoChanged | TableName | Action | ID |FieldName | OldValue

1) When an entire row is changed in the main table, lots of entries will go into this table, BUT that is very unlikely, so not a big problem (people are usually only changing one thing) 2) OldVaue (and NewValue if you want) have to be some sort of epic "anytype" since it could be any data, there might be a way to do this with RAW types or just using JSON strings to convert in and out.

Minimum data usage, stores everything you need and can be used for all tables at once. I'm researching this myself right now, but this might end up being the way I go.

For Create and Delete, just the row ID, no fields needed. On delete a flag on the main table (active?) would be good.

var s = '<div id="myDiv"></div>';
var htmlObject = document.createElement('div');
htmlObject.innerHTML = s;
htmlObject.getElementById("myDiv").style.marginTop = something;

Yes, %d means decimal, but it means decimal number system, not decimal point.

Further, as a complement to the former post, you can also control the number of decimal points to show. Try this,

System.out.printf("%.2f %.1f",d,f); // prints 1.20 1.2

For more please refer to the API docs.

The problem is

When a Scanner is closed, it will close its input source if the source implements the Closeable interface.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

Thus scan.close() closes System.in.

To fix it you can make

Scanner scan static and do not close it in PromptCustomerQty. Code below works.

public static void main (String[] args) {   

// Create a customer
// Future proofing the possabiltiies of multiple customers
Customer customer = new Customer("Will");

// Create object for each Product
// (Name,Code,Description,Price)
// Initalize Qty at 0
Product Computer = new Product("Computer","PC1003","Basic Computer",399.99); 
Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99);
Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23);

// Define internal variables 
// ## DONT CHANGE 
ArrayList<Product> ProductList = new ArrayList<Product>(); // List to store Products
String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output

// Add objects to list
ProductList.add(Computer);
ProductList.add(Monitor);
ProductList.add(Printer);

// Ask users for quantities 
PromptCustomerQty(customer, ProductList);

// Ask user for payment method
PromptCustomerPayment(customer);

// Create the header
PrintHeader(customer, formatString);

// Create Body
PrintBody(ProductList, formatString);   
}

static Scanner scan;

public static void PromptCustomerQty(Customer customer, ArrayList<Product> ProductList)               {
// Initiate a Scanner
scan = new Scanner(System.in);

// **** VARIABLES ****
int qty = 0;

// Greet Customer
System.out.println("Hello " + customer.getName());

// Loop through each item and ask for qty desired
for (Product p : ProductList) {

    do {
    // Ask user for qty
    System.out.println("How many would you like for product: " + p.name);
    System.out.print("> ");

    // Get input and set qty for the object
    qty = scan.nextInt();

    }
    while (qty < 0); // Validation

    p.setQty(qty); // Set qty for object
    qty = 0; // Reset count
}

// Cleanup

}

public static void PromptCustomerPayment (Customer customer) {
// Variables
String payment = "";

// Prompt User
do {
System.out.println("Would you like to pay in full? [Yes/No]");
System.out.print("> ");

payment = scan.next();

} while ((!payment.toLowerCase().equals("yes")) && (!payment.toLowerCase().equals("no")));

// Check/set result
if (payment.toLowerCase() == "yes") {
    customer.setPaidInFull(true);
}
else {
    customer.setPaidInFull(false);
}
}

On a side note, you shouldn't use == for String comparision, use .equals instead.

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

A LinkedList can be used as a Queue - but you need to use it right. Here is an example code :

@Test
public void testQueue() {
    LinkedList<Integer> queue = new LinkedList<>();
    queue.add(1);
    queue.add(2);
    System.out.println(queue.pop());
    System.out.println(queue.pop());
}

Output :

1
2

Remember, if you use push instead of add ( which you will very likely do intuitively ), this will add element at the front of the list, making it behave like a stack.

So this is a Queue only if used in conjunction with add.

Try this :

@Test
public void testQueue() {
    LinkedList<Integer> queue = new LinkedList<>();
    queue.push(1);
    queue.push(2);
    System.out.println(queue.pop());
    System.out.println(queue.pop());
}

Output :

2
1

If you want to be able to return to the precise version of the repository at the time you do a build it is best to tag the commit from which you make the build.

The other answers provide techniques to return the repository to the most recent commit in a branch as of a certain time-- but they might not always suffice. For example, if you build from a branch, and later delete the branch, or build from a branch that is later rebased, the commit you built from can become "unreachable" in git from any current branch. Unreachable objects in git may eventually be removed when the repository is compacted.

Putting a tag on the commit means it never becomes unreachable, no matter what you do with branches afterwards (barring removing the tag).

I found this post in google as the second top result, first was using exec :(

Anyway, while this did not suite my needs exactly.. I decided to post an answer for others with my quick but extended version of this.

SCRIPT FEATURES

• Backup file naming day by day, PREFIX-YYYY-MM-DD-POSTFIX.EXTENSION
• File Reporting / Missing
• Previous Backups Listing
• Does not zip / include previous backups ;)
• Works on windows/linux

Anyway, onto the script.. While it may look like a lot.. Remember there is excess in here.. So feel free to delete the reporting sections as needed...

Also it may look messy as well and certain things could be cleaned up easily... So dont comment about it, its just a quick script with basic comments thrown in.. NOT FOR LIVE USE.. But easy to clean up for live use!

In this example, it is run from a directory that is inside of the root www / public_html folder.. So only needs to travel up one folder to get to the root.

<?php
    // DIRECTORY WE WANT TO BACKUP
    $pathBase = '../';  // Relate Path

WHAT DOES IT DO??

It will simply zip the complete contents of the variable $pathBase and store the zip in that same folder. It does a simple detection for previous backups and skips them.

CRON BACKUP

This script i've just tested on linux and worked fine from a cron job with using an absolute url for the pathBase.

Use a js library like underscore.js for these reasons exactly. Use: union: Computes the union of the passed-in arrays: the list of unique items, in order, that are present in one or more of the arrays.

_.union([1, 2, 3], [101, 2, 1, 10], [2, 1]);
=> [1, 2, 3, 101, 10]

There are several more things you might want to audit, such as table/column names, computer/application from which an update was made, and more.

Now, this depends on how detailed auditing you really need and at what level.

We started building our own trigger-based auditing solution, and we wanted to audit everything and also have a recovery option at hand. This turned out to be too complex, so we ended up reverse engineering the trigger-based, third-party tool ApexSQL Audit to create our own custom solution.

Tips:

• Include before/after values

• Include 3-4 columns for storing the primary key (in case it’s a composite key)

• Store data outside the main database as already suggested by Robert

• Spend a decent amount of time on preparing reports – especially those you might need for recovery

• Plan for storing host/application name – this might come very useful for tracking suspicious activities

You can use the project-version package.

$ npm install --save project-version

Then

const version = require('project-version');

console.log(version);
//=>  '1.0.0'

It uses process.env.npm_package_version but fallback on the version written in the package.json in case the env var is missing for some reason.

TreeMap is an example of a SortedMap, which means that the order of the keys can be sorted, and when iterating over the keys, you can expect that they will be in order.

HashMap on the other hand, makes no such guarantee. Therefore, when iterating over the keys of a HashMap, you can't be sure what order they will be in.

HashMap will be more efficient in general, so use it whenever you don't care about the order of the keys.

Use the re.escape() function for this:

4.2.3 re Module Contents

escape(string)

Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

A simplistic example, search any occurence of the provided string optionally followed by 's', and return the match object.

def simplistic_plural(word, text):
    word_or_plural = re.escape(word) + 's?'
    return re.match(word_or_plural, text)

In case you need to parse it from a file, I find the best solution to use a HashMap<String, String> to use it inside your java code for better manipultion.

Try out this code:

public HashMap<String, String> myMethodName() throws FileNotFoundException
{
    String path = "absolute path to your file";
    BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

    Gson gson = new Gson();
    HashMap<String, String> json = gson.fromJson(bufferedReader, HashMap.class);
    return json;
}

The shortest way is: @RequestMapping({"", "/", "welcome"})

Although you can also do:

• @RequestMapping(value={"", "/", "welcome"})
• @RequestMapping(path={"", "/", "welcome"})

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

Do you care for non-English names? If so, all of the presented solutions (.split(''), [...str], Array.from(str), etc.) may give bad results, depending on language:

"????? ???????".split("") // the current president of India, Pranab Mukherjee
// returns ["?", "?", "?", "?", "?", " ", "?", "?", "?", "?", "?", "?", "?"]
// but should return ["??", "?", "?", "?", " ", "??", "?", "??", "??"]

Consider using the grapheme-splitter library for a clean standards-based split: https://github.com/orling/grapheme-splitter

Add field if not exist:

CALL addFieldIfNotExists ('settings', 'multi_user', 'TINYINT(1) NOT NULL DEFAULT 1');

        SET @ddl = CONCAT(@ddl, ' ', 'ADD COLUMN') ;
        SET @ddl = CONCAT(@ddl, ' ', field_name_IN);
        SET @ddl = CONCAT(@ddl, ' ', field_definition_IN);

        PREPARE stmt FROM @ddl;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;

    END IF;

Besides using one of the default formats you can specify any size you want in the unit you specify.

For example:

// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);

The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).

Your 1st parameter (landscape or portrait) determines what becomes the width and the height.

In the sourcecode on GitHub you can see the supported units (relative proportions to pt), and you can also see the default page formats (with their sizes in pt).

I know it's a bit old but since I recently looked into it :

let l = UILabel()
l.numberOfLines = 0
l.lineBreakMode = .ByWordWrapping
l.text = "BLAH BLAH BLAH BLAH BLAH"
l.frame.size.width = 300
l.sizeToFit()

First set the numberOfLines property to 0 so that the device understands you don't care how many lines it needs. Then specify your favorite BreakMode Then the width needs to be set before sizeToFit() method. Then the label knows it must fit in the specified width

I used this to update a excel 12 xlsx file

        System.Data.OleDb.OleDbConnection MyConnection;
        System.Data.OleDb.OleDbCommand myCommand = new System.Data.OleDb.OleDbCommand();
        MyConnection = new System.Data.OleDb.OleDbConnection("provider=Microsoft.ACE.OLEDB.12.0;Data Source='D:\\Programming\\Spreadsheet-Current.xlsx';Extended Properties='Excel 12.0;HDR=YES;';");
        MyConnection.Open();
        myCommand.Connection = MyConnection;
        string sql = "Update [ArticlesV2$] set [ID]='Test' where [ActualPageId]=114";// 
        myCommand.CommandText = sql;
        myCommand.ExecuteNonQuery();
        MyConnection.Close();

        public static void AddMiddle_LinkedList2()
        {
            var list = new LinkedList<Temp>();
            var watch = Stopwatch.StartNew();

            for (var i = start + 1; i < end; i += 2)
                list.AddLast(temp(i));
            for (int i = end - 2; i >= 0; i -= 2)
                list.AddLast(temp(i));

            watch.StopAndPrint();
        }

        //OP's original more sensible approach, but I tried to filter out
        //the intermediate iteration cost in finding the middle node.
        public static void AddMiddle_LinkedList3()
        {
            var list = new LinkedList<Temp>();
            var watch = Stopwatch.StartNew();

            for (var i = start; i < end; i++)
            {
                if (list.Count == 0)
                    list.AddLast(temp(i));
                else
                {
                    watch.Stop();
                    var curNode = list.First;
                    for (var j = 0; j < list.Count / 2; j++)
                        curNode = curNode.Next;
                    watch.Start();

                    list.AddBefore(curNode, temp(i));
                }
            }

            watch.StopAndPrint();
        }
    }
}

You can see the results are in accordance with theoretical performance others have documented here. Quite clear - LinkedList<T> gains big time in case of insertions. I haven't tested for removal from the middle of list, but the result should be the same. Of course List<T> has other areas where it performs way better like O(1) random access.

This worked. The first row had column names in it.

COPY wheat FROM 'wheat_crop_data.csv' DELIMITER ';' CSV HEADER

These two commands should do it:

:set autoindent
:set cindent

For bonus points put them in a file named .vimrc located in your home directory on linux

If you have installed SQL 2005 express edition and want to install BIDS (Business Intelligence Development Studio) then go to here Microsoft SQL Server 2005 Express Edition Toolkit

This has an option to install BIDS on my machine, and is the only way l could get hold of BIDS for SQL Server 2005 express edition.

Also this package l think has also allowed me to install both BIDS 2005 & 2008 express edition on the same machine.

Use setItem and getItem if you want to write simple strings to localStorage. Also you should be using text() if it's the text you're after as you say, else you will get the full HTML as a string.

Sample using .text()

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// alert the value to check if we got it
alert(localStorage.getItem('test'));

JSFiddle: https://jsfiddle.net/f3zLa3zc/

Storing the HTML itself

// get html
var html = $('#test')[0].outerHTML;

// set localstorage
localStorage.setItem('htmltest', html);

// test if it works
alert(localStorage.getItem('htmltest'));

JSFiddle:
https://jsfiddle.net/psfL82q3/1/

Update on user comment

A user want to update the localStorage when the div's content changes. Since it's unclear how the div contents changes (ajax, other method?) contenteditable and blur() is used to change the contents of the div and overwrite the old localStorage entry.

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// bind text to 'blur' event for div
$('#test').on('blur', function() {

    // check the new text
    var newText = $(this).text();

    // overwrite the old text
    localStorage.setItem('test', newText);

    // test if it works
    alert(localStorage.getItem('test'));

});

If we were using ajax we would instead trigger the function it via the function responsible for updating the contents.

Ctrl+P and Type "ext install cpptools" it will install everything you need to debug c and c++.

Debugging in VS code is very complete, but if you just need to compile and run: https://code.visualstudio.com/docs/languages/cpp

Look in the debugging section and it will explain everything

You haven't provided your javascript code, but the usual cause of this type of issue is not waiting till the page is loaded. Remember that most javascript is executed before the DOM is loaded, so code trying to manipulate it won't work.

To run code after the page has finished loading, use the $(document).ready callback:

$(document).ready(function(){
  $('#some-id').trigger('click');
});

The way you are doing it is indeed the recommended one (for Python 2.x).

The issue of whether the class is passed explicitly to super is a matter of style rather than functionality. Passing the class to super fits in with Python's philosophy of "explicit is better than implicit".

I know this is old, but I ran into the same issue. I'm on a Mac/Ubuntu and switch back and forth. What I have found is that just sending a simple interrupt signal to the main R process does exactly what you're looking for. I've ran scripts that went on for as long as 24 hours and the signal interrupt works very well. You should be able to run kill in terminal:

$ kill -2 pid

You can find the pid by running

$ps aux | grep exec/R

Not sure about Windows since I'm not ever on there, but I can't imagine there's not an option to do this as well in Command Prompt/Task Manager

Hope this helps!

Maybe, you should try extract your file and setup after there.

I had trouble with Mount to virtual drive by ISO and the same with RAR file. But when I extract it, it work fine

This was already asked and answered, here

To duplicate my answer:

There is never a point to declaring a static method in an interface. They cannot be executed by the normal call MyInterface.staticMethod(). If you call them by specifying the implementing class MyImplementor.staticMethod() then you must know the actual class, so it is irrelevant whether the interface contains it or not.

More importantly, static methods are never overridden, and if you try to do:

MyInterface var = new MyImplementingClass();
var.staticMethod();

the rules for static say that the method defined in the declared type of var must be executed. Since this is an interface, this is impossible.

The reason you can't execute "result=MyInterface.staticMethod()" is that it would have to execute the version of the method defined in MyInterface. But there can't be a version defined in MyInterface, because it's an interface. It doesn't have code by definition.

While you can say that this amounts to "because Java does it that way", in reality the decision is a logical consequence of other design decisions, also made for very good reason.

ForeignKey allows you receive subclasses is it definition of another class but OneToOneFields cannot do this and it is not attachable to multiple variables

Check out the Magick++ API to ImageMagick.

Note that this isn't perfect, since if you had something like, say, <a title=">"> it would break. However, it's about the closest you'd get in non-library Python without a really complex function:

import re

TAG_RE = re.compile(r'<[^>]+>')

def remove_tags(text):
    return TAG_RE.sub('', text)

However, as lvc mentions xml.etree is available in the Python Standard Library, so you could probably just adapt it to serve like your existing lxml version:

def remove_tags(text):
    return ''.join(xml.etree.ElementTree.fromstring(text).itertext())

I have been doing quite a bit of research and in attempt to resolve a different issue I ended up coming to a good portion of the solution in my other post here:

Angularjs - Form Post Data Not Posted?

The solution does not include uploading images currently but I intend to expand upon and create a clear and well working example. If updating these posts is possible I will keep them up to date all the way until a stable and easy to learn from example is compiled.

If you want to just shift everything down you can use:

Rows(1).Insert shift:=xlShiftDown

Similarly to shift everything over:

Columns(1).Insert shift:=xlShiftRight

I tried the following solution with the UITextArea and I expect this will work with UIButton as well.

First of all import this in your .m file -

#import <QuartzCore/QuartzCore.h>

and then in your loadView method add following lines

    yourButton.layer.cornerRadius = 10; // this value vary as per your desire
    yourButton.clipsToBounds = YES;

This was considered a bug in 2013: https://jira.spring.io/browse/SPR-10180

and was fixed with version 3.2.2. Problem shouldn't occur in any versions after that and your code should work just fine.

Give Xml Visualizer a try. Haven't tried the latest version yet, but I can't work without the previous one in Visual Studio 2003.

on top of displaying DataSet hierarchically, there are also a lot of other handy features such as filtering and selecting the RowState which you want to view.

My small contribution :

What is a transient field?
Basically, any field modified with the transient keyword is a transient field.

Why are transient fields needed in Java?
The transient keyword gives you some control over the serialization process and allows you to exclude some object properties from this process. The serialization process is used to persist Java objects, mostly so that their states can be preserved while they are transferred or inactive. Sometimes, it makes sense not to serialize certain attributes of an object.

Which fields should you mark transient?
Now we know the purpose of the transient keyword and transient fields, it's important to know which fields to mark transient. Static fields aren't serialized either, so the corresponding keyword would also do the trick. But this might ruin your class design; this is where the transient keyword comes to the rescue. I try not to allow fields whose values can be derived from others to be serialized, so I mark them transient. If you have a field called interest whose value can be calculated from other fields (principal, rate & time), there is no need to serialize it.

Another good example is with article word counts. If you are saving an entire article, there's really no need to save the word count, because it can be computed when article gets "deserialized." Or think about loggers; Logger instances almost never need to be serialized, so they can be made transient.

The accepted answer seems not work for me. My solution:

import time
utc_0 = int(time.mktime(datetime(1970, 01, 01).timetuple()))
def datetime2ts(dt):
    """Converts a datetime object to UTC timestamp"""
    return int(time.mktime(dt.utctimetuple())) - utc_0

In this particular case the clearest solution is the S.Lott answer

But in some complex logical conditions I would prefer use some boolean algebra to get a clear solution.

Using De Morgan's law ¬(A^B) = ¬Av¬B

not (u0 <= u and u < u0+step)
(not u0 <= u) or (not u < u0+step)
u0 > u or u >= u0+step

then

if u0 > u or u >= u0+step:
    pass

... in this case the «clear» solution is not more clear :P

You can do this by changing the gradle file.

This worked for me.

Version 5.5 of PHP will have built-in support for BCrypt, the functions password_hash() and password_verify(). Actually these are just wrappers around the function crypt(), and shall make it easier to use it correctly. It takes care of the generation of a safe random salt, and provides good default values.

The easiest way to use this functions will be:

$hashToStoreInDb = password_hash($password, PASSWORD_BCRYPT);
$isPasswordCorrect = password_verify($password, $existingHashFromDb);

This code will hash the password with BCrypt (algorithm 2y), generates a random salt from the OS random source, and uses the default cost parameter (at the moment this is 10). The second line checks, if the user entered password matches an already stored hash-value.

Should you want to change the cost parameter, you can do it like this, increasing the cost parameter by 1, doubles the needed time to calculate the hash value:

$hash = password_hash($password, PASSWORD_BCRYPT, array("cost" => 11));

In contrast to the "cost" parameter, it is best to omit the "salt" parameter, because the function already does its best to create a cryptographically safe salt.

For PHP version 5.3.7 and later, there exists a compatibility pack, from the same author that made the password_hash() function. For PHP versions before 5.3.7 there is no support for crypt() with 2y, the unicode safe BCrypt algorithm. One could replace it instead with 2a, which is the best alternative for earlier PHP versions.

The up-to-date answer (as of PHP 5.4 or newer) for generating 404 pages is to use http_response_code:

<?php
http_response_code(404);
include('my_404.php'); // provide your own HTML for the error page
die();

die() is not strictly necessary, but it makes sure that you don't continue the normal execution.

Example:

create table longtable(id number,text long);

insert into longtable values(1,'hello world');
insert into longtable values(2,'say hello!');

commit;

create or replace function search_long(r rowid) return varchar2 is
temporary_varchar varchar2(4000);
begin
select text into temporary_varchar from longtable where rowid=r;
return temporary_varchar;
end;
/


SQL> select text from longtable where search_long(rowid) like '%hello%';                                                                              

TEXT
--------------------------------------------------------------------------------
hello world
say hello!

But be careful. A PL/SQL function will only search the first 32K of LONG.

This code snippet is working properly

Here is an example

private void doOpenFile() {
    int result = myFileChooser.showOpenDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        Path path = myFileChooser.getSelectedFile().toPath();

        try {
            String contentString = "";

            for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
                contentString += s;
            }

            jText.setText(contentString);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

private void doSaveFile() {
    int result = myFileChooser.showSaveDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        // We'll be making a mytmp.txt file, write in there, then move it to
        // the selected
        // file. This takes care of clearing that file, should there be
        // content in it.
        File targetFile = myFileChooser.getSelectedFile();

        try {
            if (!targetFile.exists()) {
                targetFile.createNewFile();
            }

            FileWriter fw = new FileWriter(targetFile);

            fw.write(jText.getText());
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

References are "hidden pointers" (non-null) to things which can change (lvalues). You cannot define them to a constant. It should be a "variable" thing.

EDIT::

I am thinking of

int &x = y;

as almost equivalent of

int* __px = &y;
#define x (*__px)

where __px is a fresh name, and the #define x works only inside the block containing the declaration of x reference.

You can use Substring:

string b = a.Substring(0,3);

If I understand the question correctly you are looking for something like this:

>>> s = "a1 c2 OR c3 AND"
>>> boolops = ["AND", "OR", "NOT"]
>>> if not any(boolop in s for boolop in boolops):
...     print "no boolean operator"
... 
>>> s = "test"
>>> if not any(boolop in s for boolop in boolops):
...     print "no boolean operator"
... 
no boolean operator
>>> 

There is no way to convert a VBScript (.vbs file) into an executable (.exe file) because VBScript is not a compiled language. The process of converting source code into native executable code is called "compilation", and it's not supported by scripting languages like VBScript.

Certainly you can add your script to a self-extracting archive using something like WinZip, but all that will do is compress it. It's doubtful that the file size will shrink noticeably, and since it's a plain-text file to begin with, it's really not necessary to compress it at all. The only purpose of a self-extracting archive is that decompression software (like WinZip) is not required on the end user's computer to be able to extract or "decompress" the file. If it isn't compressed in the first place, this is a moot point.

Alternatively, as you mentioned, there are ways to wrap VBScript code files in a standalone executable file, but these are just wrappers that automatically execute the script (in its current, uncompiled state) when the user double-clicks on the .exe file. I suppose that can have its benefits, but it doesn't sound like what you're looking for.

In order to truly convert your VBScript into an executable file, you're going to have to rewrite it in another language that can be compiled. Visual Basic 6 (the latest version of VB, before the .NET Framework was introduced) is extremely similar in syntax to VBScript, but does support compiling to native code. If you move your VBScript code to VB 6, you can compile it into a native executable. Running the .exe file will require that the user has the VB 6 Run-time libraries installed, but they come built into most versions of Windows that are found now in the wild.

Alternatively, you could go ahead and make the jump to Visual Basic .NET, which remains somewhat similar in syntax to VB 6 and VBScript (although it won't be anywhere near a cut-and-paste migration). VB.NET programs will also compile to an .exe file, but they require the .NET Framework runtime to be installed on the user's computer. Fortunately, this has also become commonplace, and it can be easily redistributed if your users don't happen to have it. You mentioned going this route in your question (porting your current script in to VB Express 2008, which uses VB.NET), but that you were getting a lot of errors. That's what I mean about it being far from a cut-and-paste migration. There are some huge differences between VB 6/VBScript and VB.NET, despite some superficial syntactical similarities. If you want help migrating over your VBScript, you could post a question here on Stack Overflow. Ultimately, this is probably the best way to do what you want, but I can't promise you that it will be simple.

You can use numpy.ravel to return a flattened array from n-dimensional array:

>>> a
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])
>>> a.ravel()
array([0, 1, 2, 3, 4, 5, 6, 7, 8])

I have some vague recollections of Oracle databases needing a bit of fiddling when you reboot for the first time after installing the database. However, you haven't given us enough information to work on. To start with:

• What code are you using to connect to the database?
• It's not clear whether the database instance has been started. Can you connect to the database using sqlplus / as sysdba from within the VM?
• What has been written to the listener.log file (in %ORACLE_HOME%\network\log) since the last reboot?

EDIT: I've now been able to come up with a scenario which generates the same error message you got. It looks to me like the database you're attempting to connect to has not been started up. The example I present below uses Oracle XE on Linux, but I don't think this makes a significant difference.

First, let us confirm that the database is shut down:

$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Sat Jul 17 18:16:43 2010

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

Connected to an idle instance.

It's the text Connected to an idle instance that tells us that the database is shut down.

Using sqlplus / as sysdba connects us to the database as SYS without needing a password, but it only works on the same machine as the database itself. In your case, you'd need to run this inside the virtual machine. SYS has permission to start up and shut down the database, and to connect to it when it is shut down, but normal users don't have these permissions.

Now let us disconnect and try reconnecting as a normal user, one that does not have permission to startup/shutdown the database nor connect to it when it is down:

SQL> exit

$ sqlplus -L "user/pw@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=XE)))"

SP2-0751: Unable to connect to Oracle.  Exiting SQL*Plus

That's the error message you've been getting.

Now, let's start the database up:

$ sqlplus / as sysdba

We're in.

I hadn't seen an ORA-12505 error before because I don't normally connect to an Oracle database by entering the entire connection string on the command line. This is likely to be similar to how you are attempting to connect to the database. Usually, I either connect to a local database, or connect to a remote database by using a TNS name (these are listed in the tnsnames.ora file, in %ORACLE_HOME%\network\admin). In both of these cases you get a different error message if you attempt to connect to a database that has been shut down.

If the above doesn't help you (in particular, if the database has already been started, or you get errors starting up the database), please let us know.

EDIT 2: it seems the problems you were having were indeed because the database hadn't been started. It also appears that your database isn't configured to start up when the service starts. It is possible to get the database to start up when the service is started, and to shut down when the service is stopped. To do this, use the Oracle Administration Assistant for Windows, see here.

Try this

var d = new Date();
d.setDate(d.getDate() - 1);

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

This is the most simple solution for me:

just the current date

$tStamp = Get-Date -format yyyy_MM_dd_HHmmss

current date with some months added

$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd

You can retrieve the format strings from the CultureInfo DateTimeFormat property, which is a DateTimeFormatInfo instance. This in turn has properties like ShortDatePattern and ShortTimePattern, containing the format strings:

CultureInfo us = new CultureInfo("en-US");
string shortUsDateFormatString = us.DateTimeFormat.ShortDatePattern;
string shortUsTimeFormatString = us.DateTimeFormat.ShortTimePattern;

CultureInfo uk = new CultureInfo("en-GB");
string shortUkDateFormatString = uk.DateTimeFormat.ShortDatePattern;
string shortUkTimeFormatString = uk.DateTimeFormat.ShortTimePattern;

If you simply want to format the date/time using the CultureInfo, pass it in as your IFormatter when converting the DateTime to a string, using the ToString method:

string us = myDate.ToString(new CultureInfo("en-US"));
string uk = myDate.ToString(new CultureInfo("en-GB"));

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

I see this is a fairly old question, but this looks like one of those times when something's been written without knowledge of a language feature. The collections library exists to fulfill these purposes.

from collections import Counter
letter_counter = Counter()
for letter in 'The quick brown fox jumps over the lazy dog':
    letter_counter[letter] += 1

>>> letter_counter
Counter({' ': 8, 'o': 4, 'e': 3, 'h': 2, 'r': 2, 'u': 2, 'T': 1, 'a': 1, 'c': 1, 'b': 1, 'd': 1, 'g': 1, 'f': 1, 'i': 1, 'k': 1, 'j': 1, 'm': 1, 'l': 1, 'n': 1, 'q': 1, 'p': 1, 's': 1, 't': 1, 'w': 1, 'v': 1, 'y': 1, 'x': 1, 'z': 1})

In this example the spaces are being counted, obviously, but whether or not you want those filtered is up to you.

As for the dict.get(a_key, default_value), there have been several answers to this particular question -- this method returns the value of the key, or the default_value you supply. The first argument is the key you're looking for, the second argument is the default for when that key is not present.

You can animate it after the fadeIn completes using the callback as shown below:

$("#Friends").fadeIn('slow',function(){
  $(this).animate({'top': '-=30px'},'slow');
});

If you are using IntelliJ IDE just right click on resources package and go to new and then select Resource Boundle it automatically create a .properties file for you. This did work for me .

// 24-hour time to 12-hour time 
$time_in_12_hour_format  = date("g:i a", strtotime("13:30"));

// 12-hour time to 24-hour time 
$time_in_24_hour_format  = date("H:i", strtotime("1:30 PM"));

if You use Laravel version 5.2 Review this: https://laravel.com/docs/5.2/requests#accessing-the-request

use Illuminate\Http\Request;//Access able for All requests
...

class myController extends Controller{
   public function myfunction(Request $request){
     $name = $request->input('username');
   }
 }

If one or both of your dates are in the future, then I'm afraid you're SOL if you want to-the-second accuracy. UTC time has leap seconds that aren't known until about 6 months before they happen, so any dates further out than that can be inaccurate by some number of seconds (and in practice, since people don't update their machines that often, you may find that any time in the future is off by some number of seconds).

This gives a good explanation of the theory of designing date/time libraries and why this is so: http://www.boost.org/doc/libs/1_41_0/doc/html/date_time/details.html#date_time.tradeoffs

The Notepad++ compare plugin works perfectly for this. Just save your sheets as .csv files and compare them in Notepad++. Notepad++ gives you a nice visual diff.

#!/bin/sh

FILE="/path/to/file"

/bin/cat <<EOM >$FILE
text1
text2 # This comment will be inside of the file.
The keyword EOM can be any text, but it must start the line and be alone.
 EOM # This will be also inside of the file, see the space in front of EOM.
EOM # No comments and spaces around here, or it will not work.
text4 
EOM

In Konsole (KDE terminal) is the same, Ctrl + Shift + V

Two points to consider -

Modern hardware can overlap instructions, execute them in parallel and reorder them to make best use of the hardware. And also, any significant floating point program is likely to have significant integer work too even if it's only calculating indices into arrays, loop counter etc. so even if you have a slow floating point instruction it may well be running on a separate bit of hardware overlapped with some of the integer work. My point being that even if the floating point instructions are slow that integer ones, your overall program may run faster because it can make use of more of the hardware.

As always, the only way to be sure is to profile your actual program.

Second point is that most CPUs these days have SIMD instructions for floating point that can operate on multiple floating point values all at the same time. For example you can load 4 floats into a single SSE register and the perform 4 multiplications on them all in parallel. If you can rewrite parts of your code to use SSE instructions then it seems likely it will be faster than an integer version. Visual c++ provides compiler intrinsic functions to do this, see http://msdn.microsoft.com/en-us/library/x5c07e2a(v=VS.80).aspx for some information.

If you currently have Red Gate SQL Toolbelt, you will need to unistall that too before continuing. Somehow it adds a reference to the 2005 version of the SQL Management Studio.

Getting only the instance attributes is easy.
But getting also the class attributes without the functions is a bit more tricky.

Instance attributes only

If you only have to list instance attributes just use
for attribute, value in my_instance.__dict__.items()

>>> from __future__ import (absolute_import, division, print_function)
>>> class MyClass(object):
...   def __init__(self):
...     self.a = 2
...     self.b = 3
...   def print_instance_attributes(self):
...     for attribute, value in self.__dict__.items():
...       print(attribute, '=', value)
...
>>> my_instance = MyClass()
>>> my_instance.print_instance_attributes()
a = 2
b = 3
>>> for attribute, value in my_instance.__dict__.items():
...   print(attribute, '=', value)
...
a = 2
b = 3

Instance and class attributes

To get also the class attributes without the functions, the trick is to use callable().

But static methods are not always callable!

Therefore, instead of using callable(value) use
callable(getattr(MyClass, attribute))

Example

from __future__ import (absolute_import, division, print_function)

class MyClass(object):
   a = "12"
   b = "34"               # class attributes

   def __init__(self, c, d):
     self.c = c
     self.d = d           # instance attributes

   @staticmethod
   def mystatic():        # static method
       return MyClass.b

   def myfunc(self):      # non-static method
     return self.a

   def print_instance_attributes(self):
     print('[instance attributes]')
     for attribute, value in self.__dict__.items():
        print(attribute, '=', value)

   def print_class_attributes(self):
     print('[class attributes]')
     for attribute in self.__dict__.keys():
       if attribute[:2] != '__':
         value = getattr(self, attribute)
         if not callable(value):
           print(attribute, '=', value)

v = MyClass(4,2)
v.print_class_attributes()
v.print_instance_attributes()

Note: print_class_attributes() should be @staticmethod
  but not in this stupid and simple example.

Result for python2

$ python2 ./print_attributes.py
[class attributes]
a = 12
b = 34
[instance attributes]
c = 4
d = 2

Same result for python3

$ python3 ./print_attributes.py
[class attributes]
b = 34
a = 12
[instance attributes]
c = 4
d = 2

From the manual:

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment.

So you can do (from bash):

FOOBAR=1 make

resulting in a variable FOOBAR in your Makefile.

I am not sure why you cannot use "lat" but, if you must you can rename the columns in a derived table.

select latitude from (SELECT lat AS latitude FROM poi_table) p where latitude < 500

You can use the COALESCE function in MS SQL.

INSERT INTO t ( value ) VALUES( COALESCE(@value, 'something') )

Personally, I'm not crazy about this solution as it is a maintenance nightmare if you want to change the default value.

My preference would be Mitchel Sellers proposal, but that doesn't work in MS SQL. Can't speak to other SQL dbms.

To be highly positive you work with the actual email body (yet, still with the possibility you're not parsing the right part), you have to skip attachments, and focus on the plain or html part (depending on your needs) for further processing.

As the before-mentioned attachments can and very often are of text/plain or text/html part, this non-bullet-proof sample skips those by checking the content-disposition header:

b = email.message_from_string(a)
body = ""

if b.is_multipart():
    for part in b.walk():
        ctype = part.get_content_type()
        cdispo = str(part.get('Content-Disposition'))

        # skip any text/plain (txt) attachments
        if ctype == 'text/plain' and 'attachment' not in cdispo:
            body = part.get_payload(decode=True)  # decode
            break
# not multipart - i.e. plain text, no attachments, keeping fingers crossed
else:
    body = b.get_payload(decode=True)

BTW, walk() iterates marvelously on mime parts, and get_payload(decode=True) does the dirty work on decoding base64 etc. for you.

Some background - as I implied, the wonderful world of MIME emails presents a lot of pitfalls of "wrongly" finding the message body. In the simplest case it's in the sole "text/plain" part and get_payload() is very tempting, but we don't live in a simple world - it's often surrounded in multipart/alternative, related, mixed etc. content. Wikipedia describes it tightly - MIME, but considering all these cases below are valid - and common - one has to consider safety nets all around:

Very common - pretty much what you get in normal editor (Gmail,Outlook) sending formatted text with an attachment:

multipart/mixed
 |
 +- multipart/related
 |   |
 |   +- multipart/alternative
 |   |   |
 |   |   +- text/plain
 |   |   +- text/html
 |   |      
 |   +- image/png
 |
 +-- application/msexcel

Relatively simple - just alternative representation:

multipart/alternative
 |
 +- text/plain
 +- text/html

For good or bad, this structure is also valid:

multipart/alternative
 |
 +- text/plain
 +- multipart/related
      |
      +- text/html
      +- image/jpeg

Hope this helps a bit.

P.S. My point is don't approach email lightly - it bites when you least expect it :)

Drop server.......... Window -> Show View -> Servers. Click right - > Delete

Click right in the Project Run Configuration

and add Server again......

This directive works as a [routerLink] replacement. All you have to do is to replace your [routerLink] usages with [link]. It works with ctrl+click, cmd+click, middle click.

import {Directive, HostListener, Input} from '@angular/core'
import {Router} from '@angular/router'
import _ from 'lodash'
import qs from 'qs'

@Directive({
  selector: '[link]'
})
export class LinkDirective {
  @Input() link: string

  @HostListener('click', ['$event'])
  onClick($event) {
    // ctrl+click, cmd+click
    if ($event.ctrlKey || $event.metaKey) {
      $event.preventDefault()
      $event.stopPropagation()
      window.open(this.getUrl(this.link), '_blank')
    } else {
      this.router.navigate(this.getLink(this.link))
    }
  }

  @HostListener('mouseup', ['$event'])
  onMouseUp($event) {
    // middleclick
    if ($event.which == 2) {

      $event.preventDefault()
      $event.stopPropagation()
      window.open(this.getUrl(this.link), '_blank')
    }
  }

  constructor(private router: Router) {}

  private getLink(link): any[] {
    if ( ! _.isArray(link)) {
      link = [link]
    }

    return link
  }

  private getUrl(link): string {
    let url = ''

    if (_.isArray(link)) {
      url = link[0]

      if (link[1]) {
        url += '?' + qs.stringify(link[1])
      }
    } else {
      url = link
    }

    return url
  }
}

Try win32clipboard from the win32all package (that's probably installed if you're on ActiveState Python).

This can be logically solved using a property. Here I have a property called a key.

1. Take out any String property in the object and put it in the list.
2. Check in the list weather that property contains if so then remove it.
3. Return the object list.

List<Object> objectList = new ArrayList<>();
 List<String> keyList = new ArrayList<>();
  objectList.forEach( obj -> {
   if(keyList.contains(unAvailabilityModel.getKey())) 
         objectList.remove(unAvailabilityModel); 
    else
        keyList.add(unAvailabilityModel.getKey();
});
return objectList;

Just add 0 before the permission number:
For example - we want to give all permissions - 777
Syntax: os.chmod("file_name" , permission)

import os
os.chmod("file_name" , 0777)

Python version 3.7 does not support this syntax. It requires '0o' prefix for octal literals - this is the comment I have got in PyCharm

So for python 3.7, it will be

import os
os.chmod("file_name" , 0o777)

To make the answer simple here is a program that reads integers from the file and sorting them

f = open("input.txt", 'r')

nums = f.readlines()
nums = [int(i) for i in nums]

After reading each line of the file converting each string to a digit

nums.sort()

Sorting the numbers

f.close()

f = open("input.txt", 'w')
for num in nums:
    f.write("%d\n" %num)

f.close()

Writing them back As easy as that, Hope this helps

FWIW, here is a sort method for showing which processes are using the most virt memory.

memstat | sort -k 1 -t':' -g -r | less

Sort options are set to first column, using : as column seperator, numeric sort and sort in reverse.

According to the W3C (and they are the official source on these things), a space character in the query string (and in the query string only) may be encoded as either "%20" or "+". From the section "Query strings" under "Recommendations":

Within the query string, the plus sign is reserved as shorthand notation for a space. Therefore, real plus signs must be encoded. This method was used to make query URIs easier to pass in systems which did not allow spaces.

According to section 3.4 of RFC2396 which is the official specification on URIs in general, the "query" component is URL-dependent:

3.4. Query Component The query component is a string of information to be interpreted by the resource.

   query         = *uric

Within a query component, the characters ";", "/", "?", ":", "@", "&", "=", "+", ",", and "$" are reserved.

It is therefore a bug in the other software if it does not accept URLs with spaces in the query string encoded as "+" characters.

As for the third part of your question, one way (though slightly ugly) to fix the output from URLEncoder.encode() is to then call replaceAll("\\+","%20") on the return value.

It works for me:

<IfModule mod_rewrite.c>
 RewriteEngine On
  RewriteCond %{HTTPS} !on
  RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

and for example, http://server/foo?email=someone%40example.com redirects normally without any issues. The file .htaccess located in the website root folder (for example named public_html). It is possible to use RewriteCond %{SERVER_PORT} !^443$ instead RewriteCond %{HTTPS} !on

When you use Mongoose to store dates into MongoDB you need to use toISOString() because all dates are stored as ISOdates with miliseconds.

moment.format() 

2018-04-17T20:00:00Z

moment.toISOString() -> USE THIS TO STORE IN MONGOOSE

2018-04-17T20:00:00.000Z

After trying all the solutions and none giving acceptable results (maybe because I was working on a device with default very large fonts), the following worked for me (COMPLEX_UNIT_DIP = Device Independent Pixels):

textView.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 14);

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

Maybe (probably) I am reading the question wrongly, but are you looking for the HasExited property that will tell you that the process represented by your Process object has exited (either normally or not).

If the process you have a reference to has a UI you can use the Responding property to determine if the UI is currently responding to user input or not.

You can also set EnableRaisingEvents and handle the Exited event (which is sent asychronously) or call WaitForExit() if you want to block.

In C++20 you'll be able to use std::format to do this:

unsigned char a = -58;
std::cout << std::format("{:b}", a);

Output:

11000110

In the meantime you can use the {fmt} library, std::format is based on. {fmt} also provides the print function that makes this even easier and more efficient (godbolt):

unsigned char a = -58;
fmt::print("{:b}", a);

Disclaimer: I'm the author of {fmt} and C++20 std::format.

With the newest API, here's the code I used for it

/*params*/
NSDictionary *params = @{

                         @"fields": @"id"
                         };
/* make the API call */
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:@"me"
                              parameters:params
                              HTTPMethod:@"GET"];

[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error) {
    NSDictionary *res = result;
    //res is a dict that has the key
    NSLog([res objectForKey:@"id"]);

To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20
