You are mixing the 1.5.6 version of the jcl bridge with the 1.6.0 version of the slf4j-api; this won't work because of a few changes in 1.6.0. Use the same versions for both, i.e. 1.6.1 (the latest). I use the jcl-over-slf4j bridge all the time and it works fine.

Below is a simple way of accessing the response as a String using Apache HTTP Client library.

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;

//... 

HttpGet get;
HttpClient httpClient;

// initialize variables above

ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpClient.execute(get, responseHandler);

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

If you use Android, you can simply use android.text.format.Formatter.formatFileSize().

Alternatively, here's a solution based on this popular post:

  /**
   * Formats the bytes to a human readable format
   *
   * @param si true if each kilo==1000, false if kilo==1024
   */
  @SuppressLint("DefaultLocale")
  public static String humanReadableByteCount(final long bytes, final boolean si)
  {
    final int unit = si ? 1000 : 1024;
    if(bytes<unit)
      return bytes + " B";

    double result = bytes;
    final String unitsToUse = (si ? "k" : "K") + "MGTPE";
    int i = 0;
    final int unitsCount = unitsToUse.length();
    while(true)
    {
      result /= unit;
      if(result < unit)
        break;
      // Check if we can go further:
      if(i == unitsCount-1)
        break;
      ++i;
    }

    final StringBuilder sb = new StringBuilder(9);
    sb.append(String.format("%.1f ", result));
    sb.append(unitsToUse.charAt(i));
    if(si)
      sb.append('B');
    else sb.append('i').append('B');
    final String resultStr = sb.toString();
    return resultStr;
  }

Or in Kotlin:

/**
 * formats the bytes to a human readable format
 *
 * @param si true if each kilo==1000, false if kilo==1024
 */
@SuppressLint("DefaultLocale")
fun humanReadableByteCount(bytes: Long, si: Boolean): String? {
    val unit = if (si) 1000.0 else 1024.0
    if (bytes < unit)
        return "$bytes B"
    var result = bytes.toDouble()
    val unitsToUse = (if (si) "k" else "K") + "MGTPE"
    var i = 0
    val unitsCount = unitsToUse.length
    while (true) {
        result /= unit
        if (result < unit || i == unitsCount - 1)
            break
        ++i
    }
    return with(StringBuilder(9)) {
        append(String.format("%.1f ", result))
        append(unitsToUse[i])
        if (si) append('B') else append("iB")
    }.toString()
}

It's a lambda expression.

It means that, from the listOfCars, arg0 is one of the items of that list. With that item he is going to do, hence the ->, whatever is inside of the brackets.

In this example, he's going to return a list of cars that fit the condition

Car.SEDAN == ((Car)arg0).getStyle();

Apache commons collections has a BidiMap

I'm just wondering why nobody came up with @Email from Hibernate Validator's additional constraints. The validator itself is EmailValidator.

With Java 8 it is so simple so it doesn't even need separate method anymore:

List<Integer> range = IntStream.rangeClosed(start, end)
    .boxed().collect(Collectors.toList());

This is the code from the accepted answer above, with some changes made regarding the Base64 encoding. The code below compiles.

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

import org.apache.commons.codec.binary.Base64;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");

            Base64 b = new Base64();
            String encoding = b.encodeAsString(new String("test1:test1").getBytes());

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } 
        catch(Exception e) {
            e.printStackTrace();
        }
    }
}

$('.btnMedio').click(function(event) {
    // Preventing default action of the event
    event.preventDefault();
    // Getting the height of the document
    var n = $(document).height();
    $('html, body').animate({ scrollTop: n }, 50);
//                                       |    |
//                                       |    --- duration (milliseconds) 
//                                       ---- distance from the top
});

Use System.currentTimeMillis() or System.nanoTime() if you want even more precise reading. Usually, milliseconds is precise enough if you need to output the value to the user. Moreover, System.nanoTime() may return negative values, thus it may be possible that, if you're using that method, the return value is not correct.

A general and wide use would be to use milliseconds :

long start = System.currentTimeMillis();

... 


long end = System.currentTimeMillis();

NumberFormat formatter = new DecimalFormat("#0.00000");
System.out.print("Execution time is " + formatter.format((end - start) / 1000d) + " seconds");

Note that nanoseconds are usually used to calculate very short and precise program executions, such as unit testing and benchmarking. Thus, for overall program execution, milliseconds are preferable.

$str = "
Dear friends, I just wanted so Hello. How are you guys? I'm fine, thanks!<br />
<br />
Greetings,<br />
Bill";

echo str_replace(array("\n", "\r"), '', $str);  // echo $str in a single line

You are using ASIHTTPRequest so you need to setup your project. Read the second part here

https://allseeing-i.com/ASIHTTPRequest/Setup-instructions

The ol, ul lists will work if you want you can also use a table with border: none in the css.

Just use standard CSS variables:

Your global css (eg: styles.css)

body {
  --my-var: #000
}

In your component's css or whatever it is:

span {
  color: var(--my-var)
}

Then you can change the value of the variable directly with TS/JS by setting inline style to html element:

document.querySelector("body").style.cssText = "--my-var: #000";

Otherwise you can use jQuery for it:

$("body").css("--my-var", "#fff");

Just pass it in like any other parameter:

def a(x):
    return "a(%s)" % (x,)

def b(f,x):
    return f(x)

print b(a,10)

Your for loop looks good.

A possible while loop to accomplish the same thing:

int sum = 0;
int i = 1;
while (i <= 100) {
    sum += i;
    i++;
}
System.out.println("The sum is " + sum);

A possible do while loop to accomplish the same thing:

int sum = 0;
int i = 1;
do {
    sum += i;
    i++;
} while (i <= 100);
System.out.println("The sum is " + sum);

The difference between the while and the do while is that, with the do while, at least one iteration is sure to occur.

There are ways you can check even if you are not a paid user. You can confirm TeamID from Xcode. [Build setting] Displayed on tooltip of development team.

As stated multiple times, inversion is achieved by the -v option to grep. Let me add the (hopefully amusing) note that you could have figured this out yourself by grepping through the grep help text:

grep --help | grep invert

-v, --invert-match select non-matching lines

Notes:

• xiaobai's answer is simpler (git1.7.6+): git status --ignored
  (as detailed in "Is there a way to tell git-status to ignore the effects of .gitignore files?")
• MattDiPasquale's answer (to be upvoted) git clean -ndX works on older gits, displaying a preview of what ignored files could be removed (without removing anything)

Also interesting (mentioned in qwertymk's answer), you can also use the git check-ignore -v command, at least on Unix (doesn't work in a CMD Windows session)

git check-ignore *
git check-ignore -v *

The second one displays the actual rule of the .gitignore which makes a file to be ignored in your git repo.
On Unix, using "What expands to all files in current directory recursively?" and a bash4+:

git check-ignore **/*

(or a find -exec command)

Note: https://stackoverflow.com/users/351947/Rafi B. suggests in the comments to avoid the (risky) globstar:

git check-ignore -v $(find . -type f -print)

Make sure to exclude the files from the .git/ subfolder though.

Original answer 42009)

git ls-files -i

should work, except its source code indicates:

if (show_ignored && !exc_given) {
                fprintf(stderr, "%s: --ignored needs some exclude pattern\n",
                        argv[0]);

exc_given ?

It turns out it need one more parameter after the -i to actually list anything:

Try:

git ls-files -i --exclude-from=[Path_To_Your_Global].gitignore

(but that would only list your cached (non-ignored) object, with a filter, so that is not quite what you want)

Example:

$ cat .git/ignore
# ignore objects and archives, anywhere in the tree.
*.[oa]
$ cat Documentation/.gitignore
# ignore generated html files,
*.html
# except foo.html which is maintained by hand
!foo.html
$ git ls-files --ignored \
    --exclude='Documentation/*.[0-9]' \
    --exclude-from=.git/ignore \
    --exclude-per-directory=.gitignore

Actually, in my 'gitignore' file (called 'exclude'), I find a command line that could help you:

F:\prog\git\test\.git\info>type exclude
# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of
# exclude patterns (uncomment them if you want to use them):
# *.[oa]
# *~

So....

git ls-files --ignored --exclude-from=.git/info/exclude
git ls-files -i --exclude-from=.git/info/exclude

git ls-files --others --ignored --exclude-standard
git ls-files -o -i --exclude-standard

should do the trick.

(Thanks to honzajde pointing out in the comments that git ls-files -o -i --exclude-from... does not include cached files: only git ls-files -i --exclude-from... (without -o) does.)

As mentioned in the ls-files man page, --others is the important part, in order to show you non-cached, non-committed, normally-ignored files.

--exclude_standard is not just a shortcut, but a way to include all standard "ignored patterns" settings.

exclude-standard
Add the standard git exclusions: .git/info/exclude, .gitignore in each directory, and the user's global exclusion file.

JavaScript is case-sensitive. The b in getElementbyId should be capitalized.

var content = document.getElementById("edit").innerHTML;

I prefer to use java.util.Scanner:

try {
    Scanner scanner = new Scanner(context.openFileInput(filename)).useDelimiter("\\Z");
    StringBuilder sb = new StringBuilder();

    while (scanner.hasNext()) {
        sb.append(scanner.next());
    }

    scanner.close();

    String result = sb.toString();

} catch (IOException e) {}

Use the show_source(); function of PHP. Check for more details in show_source. This is a better method I guess.

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

There is really no advantage in using Object.create(...) over new object.

Those advocating this method generally state rather ambiguous advantages: "scalability", or "more natural to JavaScript" etc.

However, I have yet to see a concrete example that shows that Object.create has any advantages over using new. On the contrary there are known problems with it. Sam Elsamman describes what happens when there are nested objects and Object.create(...) is used:

var Animal = {
    traits: {},
}
var lion = Object.create(Animal);
lion.traits.legs = 4;
var bird = Object.create(Animal);
bird.traits.legs = 2;
alert(lion.traits.legs) // shows 2!!!

This occurs because Object.create(...) advocates a practice where data is used to create new objects; here the Animal datum becomes part of the prototype of lion and bird, and causes problems as it is shared. When using new the prototypal inheritance is explicit:

function Animal() {
    this.traits = {};
}

function Lion() { }
Lion.prototype = new Animal();
function Bird() { }
Bird.prototype = new Animal();

var lion = new Lion();
lion.traits.legs = 4;
var bird = new Bird();
bird.traits.legs = 2;
alert(lion.traits.legs) // now shows 4

Regarding, the optional property attributes that are passed into Object.create(...), these can be added using Object.defineProperties(...).

I found slimier problem. Please import the HttpClientModule in your app.module.ts file as follow:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  declarations: [
    AppComponent
],

imports: [
    BrowserModule,
    HttpClientModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

you want

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

You need to have the file /root/test/devenv/openstack-rhel/pom.xml

This file need to have the followings elements:

JSONArray successObject=new JSONArray();
JSONObject dataObject=new JSONObject();
successObject.put(dataObject.toString());

This works for me.

If you are using a Ubuntu system, use the following to Store Password Permanently:

git config --global credential.helper store

First you need to create a Service. In that Service, create a class extending LocationListener. For this, use the following code snippet of Service:

public class LocationService extends Service {
public static final String BROADCAST_ACTION = "Hello World";
private static final int TWO_MINUTES = 1000 * 60 * 2;
public LocationManager locationManager;
public MyLocationListener listener;
public Location previousBestLocation = null;

Intent intent;
int counter = 0;

@Override
public void onCreate() {
    super.onCreate();
    intent = new Intent(BROADCAST_ACTION);
}

@Override
public void onStart(Intent intent, int startId) {
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    listener = new MyLocationListener();
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 4000, 0, (LocationListener) listener);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 4000, 0, listener);
}

@Override
public IBinder onBind(Intent intent)
{
    return null;
}

protected boolean isBetterLocation(Location location, Location currentBestLocation) {
    if (currentBestLocation == null) {
        // A new location is always better than no location
        return true;
    }

    // Check whether the new location fix is newer or older
    long timeDelta = location.getTime() - currentBestLocation.getTime();
    boolean isSignificantlyNewer = timeDelta > TWO_MINUTES;
    boolean isSignificantlyOlder = timeDelta < -TWO_MINUTES;
    boolean isNewer = timeDelta > 0;

    // If it's been more than two minutes since the current location, use the new location
    // because the user has likely moved
    if (isSignificantlyNewer) {
        return true;
        // If the new location is more than two minutes older, it must be worse
    } else if (isSignificantlyOlder) {
        return false;
    }

    // Check whether the new location fix is more or less accurate
    int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy());
    boolean isLessAccurate = accuracyDelta > 0;
    boolean isMoreAccurate = accuracyDelta < 0;
    boolean isSignificantlyLessAccurate = accuracyDelta > 200;

    // Check if the old and new location are from the same provider
    boolean isFromSameProvider = isSameProvider(location.getProvider(),
            currentBestLocation.getProvider());

    // Determine location quality using a combination of timeliness and accuracy
    if (isMoreAccurate) {
        return true;
    } else if (isNewer && !isLessAccurate) {
        return true;
    } else if (isNewer && !isSignificantlyLessAccurate && isFromSameProvider) {
        return true;
    }
    return false;
}



/** Checks whether two providers are the same */
private boolean isSameProvider(String provider1, String provider2) {
    if (provider1 == null) {
        return provider2 == null;
    }
    return provider1.equals(provider2);
}



@Override
public void onDestroy() {

Add this Service any where in your project, the way you want! :)

This isn't really about whether 'divs are better than tables for layout'. Someone who understands CSS can duplicate any design using 'layout tables' pretty straightforwardly. The real win is using HTML elements for what they are there for. The reason you would not use tables for non-tablular data is the same reason you don't store integers as character strings - technology works much more easily when you use it for the purpose for which it is desgined. If it was ever necessary to use tables for layout (because of browser shortcomings in the early 1990s) it certainly isn't now.

So long as Excel can open the file, the functionality to change the format of the opened file is built in.

To convert an .html file, open it using Excel (File - Open) and then save it as a .xlsx file from Excel (File - Save as).

To do it using VBA, the code would look like this:

Sub Open_HTML_Save_XLSX()

    Workbooks.Open Filename:="C:\Temp\Example.html"
    ActiveWorkbook.SaveAs Filename:= _
        "C:\Temp\Example.xlsx", FileFormat:= _
        xlOpenXMLWorkbook

End Sub

Suprisingly nobody came up with the idea of just using a div with paddingyet, so here you go:

<div style="padding-left: 30px;">
My text
</div>

You can wrap all tasks which can fail in block, and use ignore_errors: yes with that block.

tasks:
  - name: ls
    command: ls -la
  - name: pwd
    command: pwd

  - block:
    - name: ls non-existing txt file
      command: ls -la no_file.txt
    - name: ls non-existing pic
      command: ls -la no_pic.jpg
    ignore_errors: yes 

Read more about error handling in blocks here.

simply write:

if(values > 0){
//positive
}
else{
//negative
}

Don't use exit(0); That's bad practice at the best of times. Use Yii::$app->end();

So your code would look like

$this->redirect(['index'], 302);
Yii::$app->end();

That said though the actual problem was stopping POST requests, this is the wrong solution to that problem (although it does work). To stop POST requests you need to use access control.

public function behaviors()
{
    return [
        'access' => [
            'class' => \yii\filters\AccessControl::className(),
            'only' => ['create', 'update'],
            'rules' => [
                // deny all POST requests
                [
                    'allow' => false,
                    'verbs' => ['POST']
                ],
                // allow authenticated users
                [
                    'allow' => true,
                    'roles' => ['@'],
                ],
                // everything else is denied
            ],
        ],
    ];
}

You can place each image side-by-side by writing the markdown for each image on the same line.

![alt-text-1](image1.png "title-1") ![alt-text-2](image2.png "title-2")

As long as the images aren't too large, they will display inline as demonstrated by this screen shot of a README file from GitHub:

JSPs are the View component of MVC (Model View Controller). The Controller takes the incoming request and passes it to the Model, which might be a bean that does some database access. The JSP then formats the output using HTML, CSS and JavaScript, and the output then gets sent back to the requester.

I extended ??s???? K's answer to make the code full and workable. So, when you finish filling your 'all_thumbs' list, you should put its content one by one into the bundle and then into the intent:

Bundle bundle = new Bundle();

for (int i = 0; i<all_thumbs.size(); i++)
bundle.putSerializable("extras"+i, all_thumbs.get(i));

intent.putExtras(bundle);

In order to get the extras from the intent, you need:

Bundle bundle = new Bundle();
List<Thumbnail> thumbnailObjects = new ArrayList<Thumbnail>();

// collect your Thumbnail objects
for (String key : bundle.keySet()) {
thumbnailObjects.add((Thumbnail) bundle.getSerializable(key));
}

// for example, in order to get a value of the 3-rd object you need to:
String label = thumbnailObjects.get(2).get_label();

Advantage of Serializable is its simplicity. However, I would recommend you to consider using Parcelable method when you need transfer many data, because Parcelable is specifically designed for Android and it is more efficient than Serializable. You can create Parcelable class using:

1. an online tool - parcelabler
2. a plugin for Android Studion - Android Parcelable code generator

You can use cut with a delimiter like this:

with space delim:

cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv

with tab delim:

cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv

I gave you the version of cut in which you can extract a list of intervals...

Hope it helps!

I answered a very similar question, and here is a way of doing this :

First, create a file where you would define your animations and export them. Just to make it more clear in your app.component.ts

In the following example, I used a max-height of the div that goes from 0px (when it's hidden), to 500px, but you would change that according to what you need.

This animation uses states (in and out), that will be toggle when we click on the button, which will run the animtion.

animations.ts

import { trigger, state, style, transition,
    animate, group, query, stagger, keyframes
} from '@angular/animations';

export const SlideInOutAnimation = [
    trigger('slideInOut', [
        state('in', style({
            'max-height': '500px', 'opacity': '1', 'visibility': 'visible'
        })),
        state('out', style({
            'max-height': '0px', 'opacity': '0', 'visibility': 'hidden'
        })),
        transition('in => out', [group([
            animate('400ms ease-in-out', style({
                'opacity': '0'
            })),
            animate('600ms ease-in-out', style({
                'max-height': '0px'
            })),
            animate('700ms ease-in-out', style({
                'visibility': 'hidden'
            }))
        ]
        )]),
        transition('out => in', [group([
            animate('1ms ease-in-out', style({
                'visibility': 'visible'
            })),
            animate('600ms ease-in-out', style({
                'max-height': '500px'
            })),
            animate('800ms ease-in-out', style({
                'opacity': '1'
            }))
        ]
        )])
    ]),
]

Then in your app.component, we import the animation and create the method that will toggle the animation state.

app.component.ts

import { SlideInOutAnimation } from './animations';

@Component({
  ...
  animations: [SlideInOutAnimation]
})
export class AppComponent  {
  animationState = 'in';

  ...

  toggleShowDiv(divName: string) {
    if (divName === 'divA') {
      console.log(this.animationState);
      this.animationState = this.animationState === 'out' ? 'in' : 'out';
      console.log(this.animationState);
    }
  }
}

And here is how your app.component.html would look like :

<div class="wrapper">
  <button (click)="toggleShowDiv('divA')">TOGGLE DIV</button>
  <div [@slideInOut]="animationState" style="height: 100px; background-color: red;">
  THIS DIV IS ANIMATED</div>
  <div class="content">THIS IS CONTENT DIV</div>
</div>

slideInOut refers to the animation trigger defined in animations.ts

Here is a StackBlitz example I have created : https://angular-muvaqu.stackblitz.io/

Side note : If an error ever occurs and asks you to add BrowserAnimationsModule, just import it in your app.module.ts:

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  imports: [ ..., BrowserAnimationsModule ],
  ...
})

Three simple choices.

Obvious

x, _ = func()

x, junk = func()

Hideous

x = func()[0]

And there are ways to do this with a decorator.

def val0( aFunc ):
    def pick0( *args, **kw ):
        return aFunc(*args,**kw)[0]
    return pick0

func0= val0(func)

An inner class, by definition, cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?"

A non-static nested class has full access to the members of the class within which it is nested. A static nested class does not have a reference to a nesting instance, so a static nested class cannot invoke non-static methods or access non-static fields of an instance of the class within which it is nested.

I have this issue. I suspect its due to the version of Serenity BDD and Selenium. The chromedriver process never releases until the entire test suite finishes. There are only 97 tests, but having 97 processes eat up the memory of a server that hasn't much resources may be having an affect on the performance.

To address I did 2 things (this is specific to windows).

1. before each test (annotated with @Before) get the process id (PID) of the chromedriver process with:

   List<Integer> pids = new ArrayList<Integer>();
   String out;
   Process p = Runtime.getRuntime().exec("tasklist /FI \"IMAGENAME eq chromedriver.exe*\"");
   BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
   while ((out = input.readLine()) != null) {
       String[] items = StringUtils.split(out, " ");
       if (items.length > 1 && StringUtils.isNumeric(items[1])) {
           pids.add(NumberUtils.toInt(items[1]));
       }
   }
   

2. after each test (annotated with @After) kill the PID with:

   Runtime.getRuntime().exec("taskkill /F /PID " + pid);
   

Just styling an input type="submit" like this worked for me:

.link-button { _x000D_
     background: none;_x000D_
     border: none;_x000D_
     color: #0066ff;_x000D_
     text-decoration: underline;_x000D_
     cursor: pointer; _x000D_
}

<input type="submit" class="link-button" />

Tested in Chrome, IE 7-9, Firefox

If you remove the last line, you'll create new act Activity, but your old instance will still be alive.

Do you need to restart the Activity like when the orientation is changed (i.e. your state is saved and passed to onCreate(Bundle))?

If you don't, one possible workaround would be to use one extra, dummy Activity, which would be started from the first Activity, and which job is to start new instance of it. Or just delay the call to act.finish(), after the new one is started.

If you need to save most of the state, you are getting in pretty deep waters, because it's non-trivial to pass all the properties of your state, especially without leaking your old Context/Activity, by passing it to the new instance.

Please, specify what are you trying to do.

I have found a blog article by Deborah Kurata with a nice trick how to show variable number of columns in a DataGrid:

Populating a DataGrid with Dynamic Columns in a Silverlight Application using MVVM

Basically, she creates a DataGridTemplateColumn and puts ItemsControl inside that displays multiple columns.

arrayList.toArray(new Custom[0]);

http://download.oracle.com/javase/7/docs/api/java/util/ArrayList.html#toArray%28java.lang.Object[]%29

If the only issue is height, just using divs seems to work:

<div id="header">header content</div>
<div id="content" style="height:100%">content content</div>

In a simple test, the width of header/content is different in your example and mine, but I'm not sure from your post if you're concerned about the width?

The first suggestion in latkin's answer seems good, although I would suggest the less long-winded way below.

PS c:\temp> $global:test="one"

PS c:\temp> $test
one

PS c:\temp> function changet() {$global:test="two"}

PS c:\temp> changet

PS c:\temp> $test
two

His second suggestion however about being bad programming practice, is fair enough in a simple computation like this one, but what if you want to return a more complicated output from your variable? For example, what if you wanted the function to return an array or an object? That's where, for me, PowerShell functions seem to fail woefully. Meaning you have no choice other than to pass it back from the function using a global variable. For example:

PS c:\temp> function changet([byte]$a,[byte]$b,[byte]$c) {$global:test=@(($a+$b),$c,($a+$c))}

PS c:\temp> changet 1 2 3

PS c:\temp> $test
3
3
4

PS C:\nb> $test[2]
4

I know this might feel like a bit of a digression, but I feel in order to answer the original question we need to establish whether global variables are bad programming practice and whether, in more complex functions, there is a better way. (If there is one I'd be interested to here it.)

This article can provide a lot of insight here: http://redis.io/topics/memory-optimization

There are many ways to store an array of Objects in Redis (spoiler: I like option 1 for most use cases):

1. Store the entire object as JSON-encoded string in a single key and keep track of all Objects using a set (or list, if more appropriate). For example:

   INCR id:users
   SET user:{id} '{"name":"Fred","age":25}'
   SADD users {id}
   

   Generally speaking, this is probably the best method in most cases. If there are a lot of fields in the Object, your Objects are not nested with other Objects, and you tend to only access a small subset of fields at a time, it might be better to go with option 2.

   Advantages: considered a "good practice." Each Object is a full-blown Redis key. JSON parsing is fast, especially when you need to access many fields for this Object at once. Disadvantages: slower when you only need to access a single field.

2. Store each Object's properties in a Redis hash.

   INCR id:users
   HMSET user:{id} name "Fred" age 25
   SADD users {id}
   

   Advantages: considered a "good practice." Each Object is a full-blown Redis key. No need to parse JSON strings. Disadvantages: possibly slower when you need to access all/most of the fields in an Object. Also, nested Objects (Objects within Objects) cannot be easily stored.

3. Store each Object as a JSON string in a Redis hash.

   INCR id:users
   HMSET users {id} '{"name":"Fred","age":25}'
   

   This allows you to consolidate a bit and only use two keys instead of lots of keys. The obvious disadvantage is that you can't set the TTL (and other stuff) on each user Object, since it is merely a field in the Redis hash and not a full-blown Redis key.

   Advantages: JSON parsing is fast, especially when you need to access many fields for this Object at once. Less "polluting" of the main key namespace. Disadvantages: About same memory usage as #1 when you have a lot of Objects. Slower than #2 when you only need to access a single field. Probably not considered a "good practice."

4. Store each property of each Object in a dedicated key.

   INCR id:users
   SET user:{id}:name "Fred"
   SET user:{id}:age 25
   SADD users {id}
   

   According to the article above, this option is almost never preferred (unless the property of the Object needs to have specific TTL or something).

   Advantages: Object properties are full-blown Redis keys, which might not be overkill for your app. Disadvantages: slow, uses more memory, and not considered "best practice." Lots of polluting of the main key namespace.

Overall Summary

Option 4 is generally not preferred. Options 1 and 2 are very similar, and they are both pretty common. I prefer option 1 (generally speaking) because it allows you to store more complicated Objects (with multiple layers of nesting, etc.) Option 3 is used when you really care about not polluting the main key namespace (i.e. you don't want there to be a lot of keys in your database and you don't care about things like TTL, key sharding, or whatever).

Try the following:

var div = document.createElement("div");
div.innerHTML = "topdiv";
div.appendChild(element);
document.body.appendChild(div);

It's much easier to visualize things if you think about what's really going on with "redirects" and "pipes." Redirects and pipes in bash do one thing: modify where the process file descriptors 0, 1, and 2 point to (see /proc/[pid]/fd/*).

When a pipe or "|" operator is present on the command line, the first thing to happen is that bash creates a fifo and points the left side command's FD 1 to this fifo, and points the right side command's FD 0 to the same fifo.

Next, the redirect operators for each side are evaluated from left to right, and the current settings are used whenever duplication of the descriptor occurs. This is important because since the pipe was set up first, the FD1 (left side) and FD0 (right side) are already changed from what they might normally have been, and any duplication of these will reflect that fact.

Therefore, when you type something like the following:

command 2>&1 >/dev/null | grep 'something'

Here is what happens, in order:

1. a pipe (fifo) is created. "command FD1" is pointed to this pipe. "grep FD0" also is pointed to this pipe
2. "command FD2" is pointed to where "command FD1" currently points (the pipe)
3. "command FD1" is pointed to /dev/null

So, all output that "command" writes to its FD 2 (stderr) makes its way to the pipe and is read by "grep" on the other side. All output that "command" writes to its FD 1 (stdout) makes its way to /dev/null.

If instead, you run the following:

command >/dev/null 2>&1 | grep 'something'

Here's what happens:

1. a pipe is created and "command FD 1" and "grep FD 0" are pointed to it
2. "command FD 1" is pointed to /dev/null
3. "command FD 2" is pointed to where FD 1 currently points (/dev/null)

So, all stdout and stderr from "command" go to /dev/null. Nothing goes to the pipe, and thus "grep" will close out without displaying anything on the screen.

Also note that redirects (file descriptors) can be read-only (<), write-only (>), or read-write (<>).

A final note. Whether a program writes something to FD1 or FD2, is entirely up to the programmer. Good programming practice dictates that error messages should go to FD 2 and normal output to FD 1, but you will often find sloppy programming that mixes the two or otherwise ignores the convention.

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

The commands are adduser and addgroup.

Here's a template for Docker you can use in busybox environments (alpine) as well as Debian-based environments (Ubuntu, etc.):

ENV USER=docker
ENV UID=12345
ENV GID=23456

RUN adduser \
    --disabled-password \
    --gecos "" \
    --home "$(pwd)" \
    --ingroup "$USER" \
    --no-create-home \
    --uid "$UID" \
    "$USER"

Note the following:

• --disabled-password prevents prompt for a password
• --gecos "" circumvents the prompt for "Full Name" etc. on Debian-based systems
• --home "$(pwd)" sets the user's home to the WORKDIR. You may not want this.
• --no-create-home prevents cruft getting copied into the directory from /etc/skel

The usage description for these applications is missing the long flags present in the code for adduser and addgroup.

The following long-form flags should work both in alpine as well as debian-derivatives:

adduser

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: adduser [OPTIONS] USER [GROUP]

Create new user, or add USER to GROUP

        --home DIR           Home directory
        --gecos GECOS        GECOS field
        --shell SHELL        Login shell
        --ingroup GRP        Group (by name)
        --system             Create a system user
        --disabled-password  Don't assign a password
        --no-create-home     Don't create home directory
        --uid UID            User id

One thing to note is that if --ingroup isn't set then the GID is assigned to match the UID. If the GID corresponding to the provided UID already exists adduser will fail.

addgroup

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: addgroup [-g GID] [-S] [USER] GROUP

Add a group or add a user to a group

        --gid GID  Group id
        --system   Create a system group

I discovered all of this while trying to write my own alternative to the fixuid project for running containers as the hosts UID/GID.

My entrypoint helper script can be found on GitHub.

The intent is to prepend that script as the first argument to ENTRYPOINT which should cause Docker to infer UID and GID from a relevant bind mount.

An environment variable "TEMPLATE" may be required to determine where the permissions should be inferred from.

(At the time of writing I don't have documentation for my script. It's still on the todo list!!)

You could set the timeout for that element on mouse down and clear it on mouse up:

$("a").mousedown(function() {
    // set timeout for this element
    var timeout = window.setTimeout(function() { /* … */ }, 1234);
    $(this).mouseup(function() {
        // clear timeout for this element
        window.clearTimeout(timeout);
        // reset mouse up event handler
        $(this).unbind("mouseup");
        return false;
    });
    return false;
});

With this each element gets its own timeout.

You can do this:

DECLARE @maxval TINYINT, @minval TINYINT
select @maxval=24,@minval=5

SELECT CAST(((@maxval + 1) - @minval) *
    RAND(CHECKSUM(NEWID())) + @minval AS TINYINT)

And that was taken directly from this link, I don't really know how to give proper credit for this answer.

You could try to move root/public/.htaccess to root/.htaccess and it should work

Guessing from the tag 'operand' you want to check a value?

$myValue = 5;
$minValue = 1;
$maxValue = 10;

if ($myValue >= $minValue && $myValue <= $maxValue) { 
  //do something
}

After 3 hours of searching and investigation.

I had problems with it because we have two members in team (using GitHub source control), because we didn't restrict files for packages for sending to remote repository, one of team members was send packages to server and i have pull that changes to my local.

After that i had same problem as PO, also i wasn't be able to publish my API project to server.

At the and I have just used

Update-Package -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that you have used in your solution. (For every project)

Reinstall all packages in ALL PROJECTS of the current solution:

Update-Package -ProjectName 'NameOfProject' -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that are in relation with project that you specified after "-ProjectName". And i think that this is better because i had wait for half a hour to reinstall all packages in solution.

For this many thanks to Rodolpho Brock.

Also, I would recommend you that when you pull changes from remote server, to press "Restore packages" button that will be shown by Visual studio.

I stumbled on this post looking to use scientific notation in my code, I used

4.95*Math.Pow(10,-10);

But afterwards I found out you can do

4.95E-10;

Just thought I would add this for anyone in a similar situation that I was in.

Write as

<input type="submit" ng-click="profileForm.$valid==true?updateMyProfile():''" name="submit" value="Save" class="submit" id="submit">

Please read and strongly consider my advice in the comments of your post. That being said, if you still have a good reason to do this, check out this list of crypto modules for Node. It has modules for dealing with both sha1 and base64.

From my own experience, it's hard to find a simple explanation why CORS is even a concern.

Once you understand why it's there, the headers and discussion becomes a lot clearer. I'll give it a shot in a few lines.

It's all about cookies. Cookies are stored on a client by their domain.

An example story: On your computer, there's a cookie for yourbank.com. Maybe your session is in there.

Key point: When a client makes a request to the server, it will send the cookies stored under the domain that the client is on.

You're logged in on your browser to yourbank.com. You request to see all your accounts. yourbank.com receives the pile of cookies and sends back its response (your accounts).

If another client makes a cross origin request to a server, those cookies are sent along, just as before. Ruh roh.

You browse to malicious.com. Malicious makes a bunch of requests to different banks, including yourbank.com.

Since the cookies are validated as expected, the server will authorize the response.

Those cookies get gathered up and sent along - and now, malicious.com has a response from yourbank.

Yikes.

So now, a few questions and answers become apparent:

• "Why don't we just block the browser from doing that?" Yep. CORS.
• "How do we get around it?" Have the server tell the request that CORS is OK.

The current(initial) directory of shell script is the directory from which you have called the script.

You need to add your macOS user name to the _developer group. See the posts in this thread for more information. The following command should do the trick:

sudo dscl . append /Groups/_developer GroupMembership <username>

Perhaps the best way to explain it is with an example:

1. Alice creates topic branch A, and works on it
2. Bob creates unrelated topic branch B, and works on it
3. Alice does git checkout master && git pull. Master is already up to date.
4. Bob does git checkout master && git pull. Master is already up to date.
5. Alice does git merge topic-branch-A
6. Bob does git merge topic-branch-B
7. Bob does git push origin master before Alice
8. Alice does git push origin master, which is rejected because it's not a fast-forward merge.
9. Alice looks at origin/master's log, and sees that the commit is unrelated to hers.
10. Alice does git pull --rebase origin master
11. Alice's merge commit is unwound, Bob's commit is pulled, and Alice's commit is applied after Bob's commit.
12. Alice does git push origin master, and everyone is happy they don't have to read a useless merge commit when they look at the logs in the future.

Note that the specific branch being merged into is irrelevant to the example. Master in this example could just as easily be a release branch or dev branch. The key point is that Alice & Bob are simultaneously merging their local branches to a shared remote branch.

Not possible from client side . A javascript error will be raised "Error: Permission denied to access property "document"" since the Iframe is not part of your domaine. The only solution is to fetch the page from the server side code and change the needed CSS.

A JSON notation {} represents an empty object, meaning an object without members. This is not the same as null. Neither it is string as you are trying to compare it with string "{}". I don't know which json library are you using, but try to look for method something like:

isEmptyObject() 

Only downside (it seems), is that the table cell widths are identical. Any way to get around this? – Josh Stodola Oct 12 at 15:53

Just define width of the table and width for each table cell

something like

table {border-collapse:collapse; table-layout:fixed; width:900px;}
th {background: yellow; }
td {overflow:hidden;white-space:nowrap; }
.cells1{width:300px;}
.cells2{width:500px;}
.cells3{width:200px;}

It works like a charm :o)

Simple Definition:

npm - Javascript package manager

npx - Execute npm package binaries

xrange returns an iterator and only keeps one number in memory at a time. range keeps the entire list of numbers in memory.

Have you tried Autodia yet? Last time I tried it it wasn't perfect, but it was good enough.

If you are using the Git GUI tool, there is a button named Amend last commit. Click on that button and then it will display your last commit files and message. Just edit that message, and you can commit it with a new commit message.

Or use this command from a console/terminal:

git commit -a --amend -m "My new commit message"

A quick summary of the concepts:

• Hugging => content does not want to grow
• Compression Resistance => content does not want to shrink

Example:

Say you've got a button like this:

[       Click Me      ]

and you've pinned the edges to a larger superview with priority 500.

Then, if Hugging priority > 500 it'll look like this:

[Click Me]

If Hugging priority < 500 it'll look like this:

[       Click Me      ]

If the superview now shrinks then, if the Compression Resistance priority > 500, it'll look like this

[Click Me]

Else if Compression Resistance priority < 500, it could look like this:

[Cli..]

If it doesn't work like this then you've probably got some other constraints going on that are messing up your good work!

E.g. you could have it pinned to the superview with priority 1000. Or you could have a width priority. If so, this can be helpful:

Editor > Size to Fit Content

Or can use the Extension Splitter Trickster::getExtention() function of https://github.com/secrethash/trickster

Trickster::getExtention('some-funny.image.jpg'); It returns jpg

When you do new Promise((resolve)... the type inferred was Promise<{}> because you should have used new Promise<number>((resolve).

It is interesting that this issue was only highlighted when the async keyword was added. I would recommend reporting this issue to the TS team on GitHub.

There are many ways you can get around this issue. All the following functions have the same behavior:

const whatever1 = () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever2 = async () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever3 = async () => {
    return await new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever4 = async () => {
    return Promise.resolve(4);
};

const whatever5 = async () => {
    return await Promise.resolve(4);
};

const whatever6 = async () => Promise.resolve(4);

const whatever7 = async () => await Promise.resolve(4);

In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>.

If you only want to log the query, then add 'logger' and 'profileSQL' to the jdbc url:

&logger=com.mysql.jdbc.log.Slf4JLogger&profileSQL=true

Then you will get the SQL statement below:

One thing I do is to add to .bashrc/.profile this function:

function each() {
    while read line; do
        for f in "$@"; do
            $f $line
        done
    done
}

then you can do things like

... | each command1 command2 "command3 has spaces"

which is less verbose than xargs or -exec. You could also modify the function to insert the value from the read at an arbitrary location in the commands to each, if you needed that behavior also.

@jfredsilva obviously has the simplest answer for the question:

ng-style="{ 'width' : (myObject.value == 'ok') ? '100%' : '0%' }"

However, you might really want to consider my answer for something more complex.

Ternary-like example:

<p ng-style="{width: {true:'100%',false:'0%'}[myObject.value == 'ok']}"></p>

Something more complex:

<p ng-style="{
   color:       {blueish: 'blue', greenish: 'green'}[ color ], 
  'font-size':  {0: '12px', 1: '18px', 2: '26px'}[ zoom ]
}">Test</p>

If $scope.color == 'blueish', the color will be 'blue'.

If $scope.zoom == 2, the font-size will be 26px.

angular.module('app',[]);_x000D_
function MyCtrl($scope) {_x000D_
  $scope.color = 'blueish';_x000D_
  $scope.zoom = 2;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>_x000D_
<div ng-app="app" ng-controller="MyCtrl" ng-style="{_x000D_
   color:       {blueish: 'blue', greenish: 'green'}[ color ], _x000D_
  'font-size':  {0: '12px', 1: '18px', 2: '26px'}[ zoom ]_x000D_
}">_x000D_
  color = {{color}}<br>_x000D_
  zoom = {{zoom}}_x000D_
</div>

This is in answer to your question...

I'd also like to know how to make it open up in Sublime Text 2 instead

For Windows:

git config --global core.editor "'C:/Program Files/Sublime Text 2/sublime_text.exe'"

Check that the path for sublime_text.exe is correct and adjust if needed.

For Mac/Linux:

git config --global core.editor "subl -n -w"

If you get an error message such as:

error: There was a problem with the editor 'subl -n -w'.

Create the alias for subl

sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl

Again check that the path matches for your machine.

For Sublime Text simply save cmd S and close the window cmd W to return to git.

I am assuming that you are using a C99 compiler (with support for dynamically sized arrays). The problem in your code is that at the time when the compilers sees your variable declaration it cannot know how many elements there are in the array (I am also assuming here, from the compiler error that length is not a compile time constant).

You must manually initialize that array:

int boardAux[length][length];
memset( boardAux, 0, length*length*sizeof(int) );

From The Little MongoDB Book

Yet another alternative to using joins is to denormalize your data. Historically, denormalization was reserved for performance-sensitive code, or when data should be snapshotted (like in an audit log). However, with the ever- growing popularity of NoSQL, many of which don’t have joins, denormalization as part of normal modeling is becoming increasingly common. This doesn’t mean you should duplicate every piece of information in every document. However, rather than letting fear of duplicate data drive your design decisions, consider modeling your data based on what information belongs to what document.

So,

student
{ 
    _id: ObjectId(...),
    name: 'Jane',
    courses: [
    { 
        name: 'Biology 101', 
        mark: 85, 
        id:bio101 
    },
  ]
}

If its a RESTful API data, replace the course id with a GET link to the course resource

Using truncate(), the solution could be

import re
#open the xml file for reading:
with open('path/test.xml','r+') as f:
    #convert to string:
    data = f.read()
    f.seek(0)
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>",r"<xyz>ABC</xyz>\1<xyz>\2</xyz>",data))
    f.truncate()

The @ symbol when specifying HtmlAttributes is used when the "thing" you are trying to set is a keyword c#. So for instance the word class, you cannot specify class, you must use @class.

The form's "on submit" handlers are called before the form is submitted. I don't know if there is a handler to be called after the form is submited. In the traditional non-Javascript sense the form submission will reload the page.

CloseableHttpClient is the base class of the httpclient library, the one all implementations use. Other subclasses are for the most part deprecated.

The HttpClient is an interface for this class and other classes.

You should then use the CloseableHttpClient in your code, and create it using the HttpClientBuilder. If you need to wrap the client to add specific behaviour you should use request and response interceptors instead of wrapping with the HttpClient.

This answer was given in the context of httpclient-4.3.

It really depends on many settings, on both the audio and video side of things. If you follow the compression-settings of this video, then it's approximately 3GB per hour. If you have a Mac, I would definitely recommend using 'Compressor' as it is fairly easy to use and works flawless.

As far as storage is concerned, if you're looking at 100hrs / 300GB, I would definitely go with an external hard drive. Video files are so huge, that they (even if they don't totally fill up your hard disk) really do confuse your computer. Make sure to make some time for compressing the whole thing because it takes hours and hours and hours.... for 100 hrs worth of footage, it'll take days.

The following command prints the total number of commits on the current branch.

git shortlog -s -n  | awk '{ sum += $1; } END { print sum; }' "$@"

It is made up of two parts:

1. Print the total logs number grouped by author (git shortlog -s -n)

   Example output

     1445  John C
     1398  Tom D
     1376  Chrsitopher P
      166  Justin T
      166  You
   

2. Sum up the total commit number of each author, i.e. the first argument of each line, and print the result out (awk '{ sum += $1; } END { print sum; }' "$@")

   Using the same example as above it will sum up 1445 + 1398 + 1376 + 166 + 166. Therefore the output will be:

     4,551
   

The AtomicBoolean class gives you a boolean value that you can update atomically. Use it when you have multiple threads accessing a boolean variable.

The java.util.concurrent.atomic package overview gives you a good high-level description of what the classes in this package do and when to use them. I'd also recommend the book Java Concurrency in Practice by Brian Goetz.

git clone means you are making a copy of the repository in your system.

git fork means you are copying the repository to your Github account.

git pull means you are fetching the last modified repository.

git push means you are returning the repository after modifying it.

In layman's term:

git clone is downloading and git pull is refreshing.

you could do something like (below)

var query = from p in context.T1

        join q in context.T2

        on

        new { p.Col1, p.Col2 }

        equals

         new { q.Col1, q.Col2 }

        select new {p...., q......};

It is.

test.hpp:

class A {
public:
    static int a(int i);
};

test.cpp:

#include <iostream>
#include "test.hpp"


int A::a(int i) {
    return i + 2;
}

using namespace std;
int main() {
    cout << A::a(4) << endl;
}

They're not always inline, no, but the compiler can make them.

You have by default the static endpoint for static files. Also Flask application has the following arguments:

static_url_path: can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder folder.

static_folder: the folder with static files that should be served at static_url_path. Defaults to the 'static' folder in the root path of the application.

It means that the filename argument will take a relative path to your file in static_folder and convert it to a relative path combined with static_url_default:

url_for('static', filename='path/to/file')

will convert the file path from static_folder/path/to/file to the url path static_url_default/path/to/file.

So if you want to get files from the static/bootstrap folder you use this code:

<link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='bootstrap/bootstrap.min.css') }}">

Which will be converted to (using default settings):

<link rel="stylesheet" type="text/css" href="static/bootstrap/bootstrap.min.css">

Also look at url_for documentation.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

The meta tag must be the first tag after the head tag or it will not work.

For me the C:\Program Files (x86)\Notepad++\plugins does not work.

I have to put plugins into the following directory: C:\Users\<username>\AppData\Local\Notepad++\plugins

UPDATE

There is a feature from NPP-v7.6.4 to open plugin folder:

Plugins -> Open Plugins Folder...

My problem ended up being permissions. I'm on a dev machine and copied via Homegroup. Somehow, probably based on where I copied the file to, the permissions got messed up and Management Studio couldn't read the file. Since this is dev I just gave Everyone permissions to the bak file and could then successfully restore via the GUI.

If you're using Python 2.5, this won't work, but for people using 2.6 or 2.7, try

from __future__ import print_function

print("abcd", end='')
print("efg")

results in

abcdefg

For those using 3.x, this is already built-in.

Bootstrap grid:

HTML:

  <div class="row vertical-center">
    <div class="col-xs-5"><hr></div>
    <div class="col-xs-2" style="color: white"> Text</div>
    <div class="col-xs-5"><hr></div>
  </div>

CSS:

.vertical-center{
  display: flex;
  align-items: center;
}

One trick is to create an interface that extends a generic base interface...

public interface LoadFutures extends Map<UUID, Future<LoadResult>> {}

Then you can check it with instanceof before the cast...

Object obj = context.getAttribute(FUTURES);
if (!(obj instanceof LoadFutures)) {
    String format = "Servlet context attribute \"%s\" is not of type "
            + "LoadFutures. Its type is %s.";
    String msg = String.format(format, FUTURES, obj.getClass());
    throw new RuntimeException(msg);
}
return (LoadFutures) obj;

In Kotlin you just need to set your string value like this:

<string name="song_number_and_title">"%1$d ~ %2$s"</string>

Create a text view on your layout:

<TextView android:text="@string/song_number_and_title"/>

Then do this in your code if you using Anko:

val song = database.use { // get your song from the database }
song_number_and_title.setText(resources.getString(R.string.song_number_and_title, song.number, song.title))  

You might need to get your resources from the application context.

Here is a YouTube video that explains exactly what you're wanting to do: Save and load a Keras model

There are three different saving methods that Keras makes available. These are described in the video link above (with examples), as well as below.

First, the reason you're receiving the error is because you're calling load_model incorrectly.

To save and load the weights of the model, you would first use

model.save_weights('my_model_weights.h5')

to save the weights, as you've displayed. To load the weights, you would first need to build your model, and then call load_weights on the model, as in

model.load_weights('my_model_weights.h5')

Another saving technique is model.save(filepath). This save function saves:

• The architecture of the model, allowing to re-create the model.
• The weights of the model.
• The training configuration (loss, optimizer).
• The state of the optimizer, allowing to resume training exactly where you left off.

To load this saved model, you would use the following:

from keras.models import load_model
new_model = load_model(filepath)'

Lastly, model.to_json(), saves only the architecture of the model. To load the architecture, you would use

from keras.models import model_from_json
model = model_from_json(json_string)

To make a fill completely transparent, fill="transparent" seems to work in modern browsers. But it didn't work in Microsoft Word (for Mac), I had to use fill-opacity="0".

You can not use argv[0] for that purpose, usually it does contain full path to the executable, but not nessesarily - process could be created with arbitrary value in the field.

Also mind you, the current directory and the directory with the executable are two different things, so getcwd() won't help you either.

On Windows use GetModuleFileName(), on Linux read /dev/proc/procID/.. files.

You can use re.escape():

re.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.

>>> import re
>>> re.escape('^a.*$')
'\\^a\\.\\*\\$'

If you are using a Python version < 3.7, this will escape non-alphanumerics that are not part of regular expression syntax as well.

If you are using a Python version < 3.7 but >= 3.3, this will escape non-alphanumerics that are not part of regular expression syntax, except for specifically underscore (_).

The best way to use is white-space: nowrap; This will align the text to one line.

Reproducing tim_yates answer on current hardware and adding leftShift() and concat() method to check the finding:

  'String leftShift' {
    foo << bar << baz
  }
  'String concat' {
    foo.concat(bar)
       .concat(baz)
       .toString()
  }

The outcome shows concat() to be the faster solution for a pure String, but if you can handle GString somewhere else, GString template is still ahead, while honorable mention should go to leftShift() (bitwise operator) and StringBuffer() with initial allocation:

For me, the issue was with Sentry.

1. in Xcode navigate to targets->Build Phases
2. delete the Upload Debug Symbols to Sentry phase
3. clean the build folder and try the build again

I have faced this error, Previous I had push in root directory, and now I have push another directory, so I could be remove this error and run below commands.

git add .
git commit -m "some comments"
git push --set-upstream origin master

For the complete list of attributes, the short answer is: no. The problem is that the attributes are actually defined as the arguments accepted by the getattr built-in function. As the user can reimplement __getattr__, suddenly allowing any kind of attribute, there is no possible generic way to generate that list. The dir function returns the keys in the __dict__ attribute, i.e. all the attributes accessible if the __getattr__ method is not reimplemented.

For the second question, it does not really make sense. Actually, methods are callable attributes, nothing more. You could though filter callable attributes, and, using the inspect module determine the class methods, methods or functions.

I've never had a good memory for exact wording, but in my database class I think the professor always said something like:

The data depends on the key [1NF], the whole key [2NF] and nothing but the key [3NF].

You may also need to enable the World Wide Web Service inbound firewall rule.

On Windows 7: Start -> Control Panel -> Windows Firewall -> Advanced Settings -> Inbound Rules

Find World Wide Web Services (HTTP Traffic-In) in the list and select to enable the rule. Change is pretty much immediate.

This answer is obsolete. Technology has moved on. Unless you're working with legacy systems see Joel's answer.

There is no string concatenation operator in EL. If you don't need the concatenated string to pass into some other operation, just put these expressions next to each other:

${value}${(empty value)? 'none' : ' enabled'}

This is how I solved this in ImpressPages:

//initial request with login data

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.php');
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "username=XXXXX&password=XXXXX");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie-name');  //could be empty, but cause problems on some hosts
curl_setopt($ch, CURLOPT_COOKIEFILE, '/var/www/ip4.x/file/tmp');  //could be empty, but cause problems on some hosts
$answer = curl_exec($ch);
if (curl_error($ch)) {
    echo curl_error($ch);
}

//another request preserving the session

curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/profile');
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, "");
$answer = curl_exec($ch);
if (curl_error($ch)) {
    echo curl_error($ch);
}

You have an extra -c you need to get rid of:

1. Writing JSON Parser Class

   public class JSONParser {
   
       static InputStream is = null;
       static JSONObject jObj = null;
       static String json = "";
   
       // constructor
       public JSONParser() {}
   
       public JSONObject getJSONFromUrl(String url) {
   
           // Making HTTP request
           try {
               // defaultHttpClient
               DefaultHttpClient httpClient = new DefaultHttpClient();
               HttpPost httpPost = new HttpPost(url);
   
               HttpResponse httpResponse = httpClient.execute(httpPost);
               HttpEntity httpEntity = httpResponse.getEntity();
               is = httpEntity.getContent();
   
           } catch (UnsupportedEncodingException e) {
               e.printStackTrace();
           } catch (ClientProtocolException e) {
               e.printStackTrace();
           } catch (IOException e) {
               e.printStackTrace();
           }
   
           try {
               BufferedReader reader = new BufferedReader(new InputStreamReader(
                       is, "iso-8859-1"), 8);
               StringBuilder sb = new StringBuilder();
               String line = null;
               while ((line = reader.readLine()) != null) {
                   sb.append(line + "\n");
               }
               is.close();
               json = sb.toString();
           } catch (Exception e) {
               Log.e("Buffer Error", "Error converting result " + e.toString());
           }
   
           // try parse the string to a JSON object
           try {
               jObj = new JSONObject(json);
           } catch (JSONException e) {
               Log.e("JSON Parser", "Error parsing data " + e.toString());
           }
   
           // return JSON String
           return jObj;
   
       }
   }
   

2. Parsing JSON Data
   Once you created parser class next thing is to know how to use that class. Below i am explaining how to parse the json (taken in this example) using the parser class.

   2.1. Store all these node names in variables: In the contacts json we have items like name, email, address, gender and phone numbers. So first thing is to store all these node names in variables. Open your main activity class and declare store all node names in static variables.

   // url to make request
   private static String url = "http://api.9android.net/contacts";
   
   // JSON Node names
   private static final String TAG_CONTACTS = "contacts";
   private static final String TAG_ID = "id";
   private static final String TAG_NAME = "name";
   private static final String TAG_EMAIL = "email";
   private static final String TAG_ADDRESS = "address";
   private static final String TAG_GENDER = "gender";
   private static final String TAG_PHONE = "phone";
   private static final String TAG_PHONE_MOBILE = "mobile";
   private static final String TAG_PHONE_HOME = "home";
   private static final String TAG_PHONE_OFFICE = "office";
   
   // contacts JSONArray
   JSONArray contacts = null;
   

   2.2. Use parser class to get JSONObject and looping through each json item. Below i am creating an instance of JSONParser class and using for loop i am looping through each json item and finally storing each json data in variable.

   // Creating JSON Parser instance
   JSONParser jParser = new JSONParser();
   
   // getting JSON string from URL
   JSONObject json = jParser.getJSONFromUrl(url);
   
       try {
       // Getting Array of Contacts
       contacts = json.getJSONArray(TAG_CONTACTS);
   
       // looping through All Contacts
       for(int i = 0; i < contacts.length(); i++){
           JSONObject c = contacts.getJSONObject(i);
   
           // Storing each json item in variable
           String id = c.getString(TAG_ID);
           String name = c.getString(TAG_NAME);
           String email = c.getString(TAG_EMAIL);
           String address = c.getString(TAG_ADDRESS);
           String gender = c.getString(TAG_GENDER);
   
           // Phone number is agin JSON Object
           JSONObject phone = c.getJSONObject(TAG_PHONE);
           String mobile = phone.getString(TAG_PHONE_MOBILE);
           String home = phone.getString(TAG_PHONE_HOME);
           String office = phone.getString(TAG_PHONE_OFFICE);
   
       }
   } catch (JSONException e) {
       e.printStackTrace();
   }
   

I've faced the same issue today. Turned out to be I forgot to mention @Service/@Component annotation for my service implementation file, for which spring is not able autowire and failing to create the bean.

Here is my solution - The method takes an array of integers(assuming the range between 0 to 100) as input and returns the number of occurrences of each element.

let's say the input is [21,34,43,21,21,21,45,65,65,76,76,76]. So the output would be in a map and it is: {34=1, 21=4, 65=2, 76=3, 43=1, 45=1}

public Map<Integer, Integer> countOccurrence(int[] numbersToProcess) {
    int[] possibleNumbers = new int[100];
    Map<Integer, Integer> result = new HashMap<Integer, Integer>();

    for (int i = 0; i < numbersToProcess.length; ++i) {
      possibleNumbers[numbersToProcess[i]] = possibleNumbers[numbersToProcess[i]] + 1;
      result.put(numbersToProcess[i], possibleNumbers[numbersToProcess[i]]);
    }

    return result;
}

In Linux and Mac there are not default shortcuts, so try to set your custom shortcut and be careful about don't choose a hotkey used (For example, CTRL+U is taken for uncomment)

1. File-> Preferences -> Keyboard Shortcuts.
2. Type 'transfrom' in the search input to find transform shortcuts.
3. Edit your key combination.

In my case I have CTRL+U CTRL+U for transform to uppercase and CTRL+L CTRL+L for transform to lowercase

Just in case, for Mac instead of CTRL I used ?

$htmlIngressCss='<style>';
$multiOptions = array("" => "All");
$resIn = $this->commonDB->getIngressTrunk();
while ($row = $resIn->fetch()) {
    if($row['IsActive']==0){
        $htmlIngressCss .= '.ingressClass select, option[value="'.$row['TrunkInfoID'].'"] {color:red;font-weight:bold;}';
    }
    $multiOptions[$row['TrunkInfoID']] = $row['IngressTrunkName'];
}
$htmlIngressCss.='</style>';

add $htmlIngressCss in your html portion :)

I am using project is not Spring or spring boot based application. I have multiple subprojects and they are nested one within another. The answers shown here supports on first level of subproject. If I added another sub project for source code attachement, it is not allowing me saying folder already exists error.

Looks like eclipse is out dated IDE. I am using the latest version of Eclipse version 2015-2019. It is killing all my time.

My intension is run the application in debug mode navigate through the sub projects which are added as external dependencies (non modifiable).

IMO, the provider is telling you to change the service endpoint (i.e. where to reach the web service), not the client endpoint (I don't understand what this could be). To change the service endpoint, you basically have two options.

Use the Binding Provider to set the endpoint URL

The first option is to change the BindingProvider.ENDPOINT_ADDRESS_PROPERTY property value of the BindingProvider (every proxy implements javax.xml.ws.BindingProvider interface):

...
EchoService service = new EchoService();
Echo port = service.getEchoPort();

/* Set NEW Endpoint Location */
String endpointURL = "http://NEW_ENDPOINT_URL";
BindingProvider bp = (BindingProvider)port;
bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpointURL);

System.out.println("Server said: " + echo.echo(args[0]));
...

The drawback is that this only works when the original WSDL is still accessible. Not recommended.

Use the WSDL to get the endpoint URL

The second option is to get the endpoint URL from the WSDL.

...
URL newEndpoint = new URL("NEW_ENDPOINT_URL");
QName qname = new QName("http://ws.mycompany.tld","EchoService"); 

EchoService service = new EchoService(newEndpoint, qname);
Echo port = service.getEchoPort();

System.out.println("Server said: " + echo.echo(args[0]));
...

My answer might not be solution to your question but it will surely help others looking for similar issue like this one: javax.net.ssl.SSLHandshakeException: Chain validation failed

You just need to check your Android Device's Date and Time, it should be fix the issue. This resoled my problem.

i've faced the same problem when copying data from ssms to excel. the date format got messed up. at last i changed my laptop's system date format to yyyy-mm-dd from yyyy/mm/dd. everything works just fine.

The property event.which is added when using jQuery to avoid browser differences. See docs.

The which property will be undefined if you are not using jQuery.

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

I know this has already been answered, but here is an example for the people who are trying to use SQL Server Types in a vb project:

            Imports System
            Imports System.IO
            Imports System.Runtime.InteropServices

            Namespace SqlServerTypes
                Public Class Utilities



                    <DllImport("kernel32.dll", CharSet:=CharSet.Auto, SetLastError:=True)>
                    Public Shared Function LoadLibrary(ByVal libname As String) As IntPtr

                    End Function

                    Public Shared Sub LoadNativeAssemblies(ByVal rootApplicationPath As String)
                        Dim nativeBinaryPath = If(IntPtr.Size > 4, Path.Combine(rootApplicationPath, "SqlServerTypes\x64\"), Path.Combine(rootApplicationPath, "SqlServerTypes\x86\"))
                        LoadNativeAssembly(nativeBinaryPath, "msvcr120.dll")
                        LoadNativeAssembly(nativeBinaryPath, "SqlServerSpatial140.dll")
                    End Sub

                    Private Shared Sub LoadNativeAssembly(ByVal nativeBinaryPath As String, ByVal assemblyName As String)
                        Dim path = System.IO.Path.Combine(nativeBinaryPath, assemblyName)
                        Dim ptr = LoadLibrary(path)

                        If ptr = IntPtr.Zero Then
                            Throw New Exception(String.Format("Error loading {0} (ErrorCode: {1})", assemblyName, Marshal.GetLastWin32Error()))
                        End If
                    End Sub
                End Class
            End Namespace

Just git rm subdir will be ok. that will remove the subdir as an index.

simple way :

   -(void) viewDidLoad {
   self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage       imageNamed:@"background.png"]];
    [super viewDidLoad];
    }

Classic example "Index in Books"

Consider a "Book" of 1000 pages, divided by 10 Chapters, each section with 100 pages.

Simple, huh?

Now, imagine you want to find a particular Chapter that contains a word "Alchemist". Without an index page, you have no other option than scanning through the entire book/Chapters. i.e: 1000 pages.

This analogy is known as "Full Table Scan" in database world.

But with an index page, you know where to go! And more, to lookup any particular Chapter that matters, you just need to look over the index page, again and again, every time. After finding the matching index you can efficiently jump to that chapter by skipping the rest.

But then, in addition to actual 1000 pages, you will need another ~10 pages to show the indices, so totally 1010 pages.

Thus, the index is a separate section that stores values of indexed column + pointer to the indexed row in a sorted order for efficient look-ups.

Things are simple in schools, isn't it? :P

Of course the "You shall not instantiate an item of this class" statement has been violated, but if this is the logic behind that, then we should all throw AssertionErrors everywhere, and that is obviously not what happens.

The code isn't saying the user shouldn't call the zero-args constructor. The assertion is there to say that as far as the programmer is aware, he/she has made it impossible to call the zero-args constructor (in this case by making it private and not calling it from within Example's code). And so if a call occurs, that assertion has been violated, and so AssertionError is appropriate.

if you are using Android Studio in MAC OS X , you could exec the following command in your terminal app:

echo 'alias adb="/Applications/Android\ Studio.app/sdk/platform-tools/adb"' >> .bashrc
exec $SHELL

and next:

adb devices

and you should be showing a list with your android devices connected via USB cable in your MAC, for example something like this:

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
deb7bed5        device

Based on the reference of java.util.Collections.addAll(Collection<? super String> c, String... elements) its implementation is similar to your first method, it says

Adds all of the specified elements to the specified collection. Elements to be added may be specified individually or as an array. The behavior of this convenience method is identical to that of c.addAll(Arrays.asList(elements)), but this method is likely to run significantly faster under most implementations.

Its implementation in jdk is (jdk7)

public static <T> boolean addAll(Collection<? super T> c, T... elements) {
    boolean result = false;
    for (T element : elements)
        result |= c.add(element);
    return result;
}

So among your samples the better approach must be Collections.addAll(list, array);

Since Java 8, we can use Stream api which may perform better

Eg:-

String[] array = {"item1", "item2", "item3"};

Stream<String> stream = Stream.of(array);

//if the array is extremely large 
stream = stream.parallel();

final List<String> list = stream.collect(Collectors.toList());

If the array is very large we can do it as a batch operation in parallel using parallel stream (stream = stream.parallel()) that will utilize all CPUs to finish the task quickly. If the array length is very small parallel stream will take more time than sequential stream.

Cshtml files are the ones used by Razor and as stated as answer for this question, their main advantage is that they can be rendered inside unit tests. The various answers to this other topic will bring a lot of other interesting points.

You say that if int(splitLine[0]) > int(lastUnix): is causing the trouble, but you don't actually show anything which suggests that. I think this line is the problem instead:

print 'Pulled', + stock

Do you see why this line could cause that error message? You want either

>>> stock = "AAAA"
>>> print 'Pulled', stock
Pulled AAAA

or

>>> print 'Pulled ' + stock
Pulled AAAA

not

>>> print 'Pulled', + stock
PulledTraceback (most recent call last):
  File "<ipython-input-5-7c26bb268609>", line 1, in <module>
    print 'Pulled', + stock
TypeError: bad operand type for unary +: 'str'

You're asking Python to apply the + symbol to a string like +23 makes a positive 23, and she's objecting.

My solution to this (which hasn't caused any performance issues):

1. Extend the array object with a method remove (i'm sure you will need it more than just one time):

Array.prototype.remove = function(from, to) {
  var rest = this.slice((to || from) + 1 || this.length);
  this.length = from < 0 ? this.length + from : from;
  return this.push.apply(this, rest);
};

I'm using it in all of my projects and credits go to John Resig John Resig's Site

2. Using forEach and a basic check:

$scope.items.forEach(function(element, index, array){
          if(element.name === 'ted'){
              $scope.items.remove(index);
          }
        });

At the end the $digest will be fired in angularjs and my UI is updated immediately without any recognizable lag.

Put this .gitignore into the folder, then git add .gitignore.

*
*/
!.gitignore

The * line tells git to ignore all files in the folder, but !.gitignore tells git to still include the .gitignore file. This way, your local repository and any other clones of the repository all get both the empty folder and the .gitignore it needs.

Edit: May be obvious but also add */ to the .gitignore to also ignore subfolders.

look at overloaded Sort method of the List class. there are some ways to to it. one of them: your custom class has to implement IComparable interface then you cam use Sort method of the List class.

You should use the pickaxe (-S) option of git log.

To search for Foo:

git log -SFoo -- path_containing_change
git log -SFoo --since=2009.1.1 --until=2010.1.1 -- path_containing_change

See Git history - find lost line by keyword for more.

As Jakub Narebski commented:

• this looks for differences that introduce or remove an instance of <string>. It usually means "revisions where you added or removed line with 'Foo'".

• the --pickaxe-regex option allows you to use extended POSIX regex instead of searching for a string. Example (from git log): git log -S"frotz\(nitfol" --pickaxe-regex

As Rob commented, this search is case-sensitive - he opened a follow-up question on how to search case-insensitive.

In my case with the given code, I was able to parse the value of the passed parameter in this way.

const express = require('express');
const bodyParser = require('body-parser');

const app = express(); 
app.use(bodyParser.urlencoded({ extended: false }));
//url/par1=val1&par2=val2 
let val1= req.body.par1;
let val2 = req.body.par2;

I've created a custom PagerAdapters library to change items in PagerAdapters dynamically.

You can change items dynamically like following by using this library.

@Override
protected void onCreate(Bundle savedInstanceState) {
        /** ... **/
    adapter = new MyStatePagerAdapter(getSupportFragmentManager()
                            , new String[]{"1", "2", "3"});
    ((ViewPager)findViewById(R.id.view_pager)).setAdapter(adapter);
     adapter.add("4");
     adapter.remove(0);
}

class MyPagerAdapter extends ArrayViewPagerAdapter<String> {

    public MyPagerAdapter(String[] data) {
        super(data);
    }

    @Override
    public View getView(LayoutInflater inflater, ViewGroup container, String item, int position) {
        View v = inflater.inflate(R.layout.item_page, container, false);
        ((TextView) v.findViewById(R.id.item_txt)).setText(item);
        return v;
    }
}

Thils library also support pages created by Fragments.

EDIT: Super Redux Version

Try port 587 instead of 465. Port 465 is technically deprecated.

After a bunch of packet sniffing I figured it out. First, here's the short answer:

The .NET SmtpClient only supports encryption via STARTTLS. If the EnableSsl flag is set, the server must respond to EHLO with a STARTTLS, otherwise it will throw an exception. See the MSDN documentation for more details.

Second, a quick SMTP history lesson for those who stumble upon this problem in the future:

Back in the day, when services wanted to also offer encryption they were assigned a different port number, and on that port number they immediately initiated an SSL connection. As time went on they realized it was silly to waste two port numbers for one service and they devised a way for services to allow plaintext and encryption on the same port using STARTTLS. Communication would start using plaintext, then use the STARTTLS command to upgrade to an encrypted connection. STARTTLS became the standard for SMTP encryption. Unfortunately, as it always happens when a new standard is implemented, there is a hodgepodge of compatibility with all the clients and servers out there.

In my case, my user was trying to connect the software to a server that was forcing an immediate SSL connection, which is the legacy method that is not supported by Microsoft in .NET.

For Jquery UI buttons this works :

$("#buttonId").button( "option", "disabled", true | false );

One straight forward way to ensure the object is initialized without any error is to test the object's type instance.

Here is an example :

p = SomeClass(param1=_param1_value)
self.assertTrue(isinstance(p, SomeClass))

White spaces in the value

There are many great answers here, but I found them all lacking support for white space in the value:

DATABASE_CLIENT_HOST=host db-name db-user 0.0.0.0/0 md5

I have found 2 solutions that work whith such values with support for empty lines and comments.

One based on sed and @javier-buzzi answer:

source <(sed -e /^$/d -e /^#/d -e 's/.*/declare -x "&"/g' .env)

And one with read line in a loop based on @john1024 answer

while read -r line; do declare -x "$line"; done < <(egrep -v "(^#|^\s|^$)" .env)

The key here is in using declare -x and putting line in double quotes. I don't know why but when you reformat the loop code to multiple lines it won't work — I'm no bash programmer, I just gobbled together these, it's still magic to me :)

Use the following code:

System.out.println("\f");

'\f' is an escape sequence which represents FormFeed. This is what I have used in my projects to clear the console. This is simpler than the other codes, I guess.

In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.

This is helpful when your equals method call throws some exception e.g. NullPointerException;

     boolean isMatch = false;

     try{
         isMatch = email1.equals (email2);
      }catch(NullPointerException npe){
         .....
      }
      System.out.print("Match=="+isMatch);
      if(isMatch){
        ......
      }

Log.v("blah", "blah blah");

You need to add the android Log view in eclipse to see them. There are also other methods depending on the severity of the message (error, verbose, warning, etc..).

You can try this

 $('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});

The $('div.easy_editor') refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.

Add type="button" to the button.

<button name="data" type="button" onclick="getData()">Click</button>

The default value of type for a button is submit, which self posts the form in your case and makes it look like a refresh.

You have to make sure you take care of file names with more then one dot. example: c:\.directoryname\file.name.with.too.many.dots.ext would not be handled correctly by strchr or find.

My favorite would be the boost filesystem library that have an extension(path) function

In some cases, when you check your default encoding (print sys.getdefaultencoding()), it returns that you are using ASCII. If you change to UTF-8, it doesn't work, depending on the content of your variable. I found another way:

import sys
reload(sys)  
sys.setdefaultencoding('Cp1252')

Many answers have explained how to call a method from the parent which has been overridden in the child.

However

"how do you call a parent class's method from child class?"

could also just mean:

"how do you call inherited methods?"

You can call methods inherited from a parent class just as if they were methods of the child class, as long as they haven't been overwritten.

e.g. in python 3:

class A():
  def bar(self, string):
    print("Hi, I'm bar, inherited from A"+string)

class B(A):
  def baz(self):
    self.bar(" - called by baz in B")

B().baz() # prints out "Hi, I'm bar, inherited from A - called by baz in B"

yes, this may be fairly obvious, but I feel that without pointing this out people may leave this thread with the impression you have to jump through ridiculous hoops just to access inherited methods in python. Especially as this question rates highly in searches for "how to access a parent class's method in Python", and the OP is written from the perspective of someone new to python.

I found: https://docs.python.org/3/tutorial/classes.html#inheritance to be useful in understanding how you access inherited methods.

@jh314 is correct. In AndroidManifest.xml,

 <application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"></application>

In style.xml

  <!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorAccent">@color/red</item>
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

the item name must be colorAccent,it decides the application's widgets default color.

But if you want to change the color in code,Maybe @aknay's answer is correct.

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

Use WinRar. It will open the folder structure for you in intact manner. Also allows in-archive editing, while preserving paths.

Afterall, a JAR file is a ZIP archive only.

Maven acts as both a dependency management tool - it can be used to retrieve jars from a central repository or from a repository you set up - and as a declarative build tool. The difference between a "declarative" build tool and a more traditional one like ant or make is you configure what needs to get done, not how it gets done. For example, you can say in a maven script that a project should be packaged as a WAR file, and maven knows how to handle that.

Maven relies on conventions about how project directories are laid out in order to achieve its "declarativeness." For example, it has a convention for where to put your main code, where to put your web.xml, your unit tests, and so on, but also gives the ability to change them if you need to.

You should also keep in mind that there is a plugin for running ant commands from within maven:

http://maven.apache.org/plugins/maven-ant-plugin/

Also, maven's archetypes make getting started with a project really fast. For example, there is a Wicket archetype, which provides a maven command you run to get a whole, ready-to-run hello world-type project.

https://wicket.apache.org/start/quickstart.html

Above, @drowa shows a verbose approach that I agree with. It's good because it avoids the 3-value logic problem. Many of the other approaches provided here will fail in subtle and unexpected ways when negated because they're treating null as equivalent to false which it is not.

However, I have a workflow that I find makes it convenient-ish, here's a regex. Given code of the form

(leftSide <=> rightSide)

regex find this:

\(([a-zA-Z0-9_.@]+)\s*<=>\s*([a-zA-Z0-9_.@]+)\)

and replace with this:

(/*$1 <=> $2*/ ($1 IS NULL AND $2 IS NULL) OR ($1 IS NOT NULL AND $2 IS NOT NULL AND $1 = $2))

So I write the (leftSide <=> rightSide) code and apply the above regex transformation to get the expanded form. It'd be nicer if MSSQL offered some kind of macro expansion so I wouldn't have to do it manually, but it doesn't.

@Drowa's answer quoted for reference:

Equals comparison:

((f1 IS NULL AND f2 IS NULL) OR (f1 IS NOT NULL AND f2 IS NOT NULL AND f1 = f2))

Not Equal To comparison: Just negate the Equals comparison above.

NOT ((f1 IS NULL AND f2 IS NULL) OR (f1 IS NOT NULL AND f2 IS NOT NULL AND f1 = f2))

Is it verbose? Yes, it is. However it's efficient since it doesn't call any function. The idea is to use short circuit in predicates to make sure the equal operator (=) is used only with non-null values, otherwise null would propagate up in the expression tree.

better. that exactly will work.

let mx = Matrix(9, 9);

function Matrix(w, h){
    let mx = Array(w);
    for(let i of mx.keys())
        mx[i] = Array(h);
    return mx;
}

what was shown

Array(9).fill(Array(9)); // Not correctly working

It does not work, because all cells are fill with one array

change

print item

to

print "\033[K", item, "\r",
sys.stdout.flush()

• "\033[K" clears to the end of the line
• the \r, returns to the beginning of the line
• the flush statement makes sure it shows up immediately so you get real-time output.

Use the .val() method to get the actual value of the element you need.

Select First two Character in selected Field with Left(string,Number of Char in int)

I have added/subtracted some values to adjust my view. Please do these lines only after whole view has been inflated.

Action Definition

const selectSlice = () => {

Action Dispatch

store.dispatch({

Make sure the object structure of action defined is same as action dispatched. In my case, while dispatching action, type was not assigned to property type.

in onCreate method write-

Toolbar toolbar = findViewById(R.id.tool);
    setSupportActionBar(toolbar);
    if (getSupportActionBar() != null) {
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
    }
}
@Override
public boolean onSupportNavigateUp() {
    onBackPressed();
    return true;
}
@Override
public void onBackPressed() {
    super.onBackPressed();
    startActivity(new Intent(ActivityOne.this, ActivityTwo.class));
    finish();
}

All of the suggestions above work, but if you want your computations to by more efficient, you should take advantage of numpy vector operations (as pointed out here).

import pandas as pd
import numpy as np


df = pd.DataFrame ({'a' : np.random.randn(6),
             'b' : ['foo', 'bar'] * 3,
             'c' : np.random.randn(6)})

Example 1: looping with pandas.apply():

%%timeit
def my_test2(row):
    return row['a'] % row['c']

df['Value'] = df.apply(my_test2, axis=1)

The slowest run took 7.49 times longer than the fastest. This could mean that an intermediate result is being cached. 1000 loops, best of 3: 481 µs per loop

Example 2: vectorize using pandas.apply():

%%timeit
df['a'] % df['c']

The slowest run took 458.85 times longer than the fastest. This could mean that an intermediate result is being cached. 10000 loops, best of 3: 70.9 µs per loop

Example 3: vectorize using numpy arrays:

%%timeit
df['a'].values % df['c'].values

The slowest run took 7.98 times longer than the fastest. This could mean that an intermediate result is being cached. 100000 loops, best of 3: 6.39 µs per loop

So vectorizing using numpy arrays improved the speed by almost two orders of magnitude.

SELECT MONTHNAME( `col1` ) FROM `table_name` 

Make this in your test.ps1, at the first line

param(
[string]$a
)

Write-Host $a

Then you can call it with

./Test.ps1 "Here is your text"

From: http://wiki.apache.org/httpd/FAQ#Where_can_I_download_.28certified.29_64_bit_Apache_httpd_binaries_for_Windows.3F

Where can I download (certified) 64 bit Apache httpd binaries for Windows?

Right now, there are none. The Apache Software Foundation produces Open Source Software. The 32 bit binaries provided are a courtesy of the community members.

Though there are some unofficial e.g. http://www.apachelounge.com/download/win64/, but I have no idea if they can be trusted.

You can use:

$("#tagscloud span").text("Your text here");

The same code will also work for the second case. You could also use:

$("#tagscloud #WebPartCaptionWPQ2").text("Your text here");

It can also be done with a positive assertion of removal, like this:

textContent = textContent.replace(/[\u{0080}-\u{FFFF}]/gu,"");

This uses unicode. In Javascript, when expressing unicode for a regular expression, the characters are specified with the escape sequence \u{xxxx} but also the flag 'u' must present; note the regex has flags 'gu'.

I called this a "positive assertion of removal" in the sense that a "positive" assertion expresses which characters to remove, while a "negative" assertion expresses which letters to not remove. In many contexts, the negative assertion, as stated in the prior answers, might be more suggestive to the reader. The circumflex "^" says "not" and the range \x00-\x7F says "ascii," so the two together say "not ascii."

textContent = textContent.replace(/[^\x00-\x7F]/g,"");

That's a great solution for English language speakers who only care about the English language, and its also a fine answer for the original question. But in a more general context, one cannot always accept the cultural bias of assuming "all non-ascii is bad." For contexts where non-ascii is used, but occasionally needs to be stripped out, the positive assertion of Unicode is a better fit.

A good indication that zero-width, non printing characters are embedded in a string is when the string's "length" property is positive (nonzero), but looks like (i.e. prints as) an empty string. For example, I had this showing up in the Chrome debugger, for a variable named "textContent":

> textContent
""
> textContent.length
7

This prompted me to want to see what was in that string.

> encodeURI(textContent)
"%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B"

This sequence of bytes seems to be in the family of some Unicode characters that get inserted by word processors into documents, and then find their way into data fields. Most commonly, these symbols occur at the end of a document. The zero-width-space "%E2%80%8B" might be inserted by CK-Editor (CKEditor).

encodeURI()  UTF-8     Unicode  html     Meaning
-----------  --------  -------  -------  -------------------
"%E2%80%8B"  EC 80 8B  U 200B   ​  zero-width-space
"%E2%80%8E"  EC 80 8E  U 200E   ‎  left-to-right-mark
"%E2%80%8F"  EC 80 8F  U 200F   ‏  right-to-left-mark

Some references on those:

http://www.fileformat.info/info/unicode/char/200B/index.htm

https://en.wikipedia.org/wiki/Left-to-right_mark

Note that although the encoding of the embedded character is UTF-8, the encoding in the regular expression is not. Although the character is embedded in the string as three bytes (in my case) of UTF-8, the instructions in the regular expression must use the two-byte Unicode. In fact, UTF-8 can be up to four bytes long; it is less compact than Unicode because it uses the high bit (or bits) to escape the standard ascii encoding. That's explained here:

https://en.wikipedia.org/wiki/UTF-8

The following would work:

myarray: [
  String1, String2, String3,
  String4, String5, String5, String7
]

I tested it using the snakeyaml implementation, I am not sure about other implementations though.

Tims answer seems to me as misleading. Especially when urllib2 does not return expected code. For example this Error will be fatal (believe or not - it is not uncommon one when downloading urls):

AttributeError: 'URLError' object has no attribute 'code'

Fast, but maybe not the best solution would be code using nested try/except block:

import urllib2
try:
    urllib2.urlopen("some url")
except urllib2.HTTPError, err:
    try:
        if err.code == 404:
            # Handle the error
        else:
            raise
    except:
        ...

Based on the C99 Specification: a == (a / b) * b + a % b

We can write a function to calculate (a % b) == a - (a / b) * b!

int remainder(int a, int b)
{
    return a - (a / b) * b;
}

For modulo operation, we can have the following function (assuming b > 0)

int mod(int a, int b)
{
    int r = a % b;
    return r < 0 ? r + b : r;
}

My conclusion is that a % b in C is a remainder operation and NOT a modulo operation.

I had the same problem today. To fix I downgraded firefox version 51 to 47 and it's working.

Note: I'm using a Linux Ubuntu Mate, in a Virtual Box, with host being another Ubuntu Mate. All OS are 64 bits and firefox also.

This will work for a number greater than 0. You don't need to convert the number into string:

function convertNumberToDigitArray(number) {
    const arr = [];
    while (number > 0) {
        let lastDigit = number % 10;
        arr.push(lastDigit);
        number = Math.floor(number / 10);
    }
    return arr;
}

origin is an alias on your system for a particular remote repository. It's not actually a property of that repository.

By doing

git push origin branchname

you're saying to push to the origin repository. There's no requirement to name the remote repository origin: in fact the same repository could have a different alias for another developer.

Remotes are simply an alias that store the URL of repositories. You can see what URL belongs to each remote by using

git remote -v

In the push command, you can use remotes or you can simply use a URL directly. An example that uses the URL:

git push [email protected]:git/git.git master

<?php
if (in_array('your_variable', $Your_array)) {
    $redImg = 'true code here';
} else {
    $redImg = 'false code here';
} 
?>

If you simply need a new byte array, then use the following:

byte[] Combine(byte[] a1, byte[] a2, byte[] a3)
{
    byte[] ret = new byte[a1.Length + a2.Length + a3.Length];
    Array.Copy(a1, 0, ret, 0, a1.Length);
    Array.Copy(a2, 0, ret, a1.Length, a2.Length);
    Array.Copy(a3, 0, ret, a1.Length + a2.Length, a3.Length);
    return ret;
}

Alternatively, if you just need a single IEnumerable, consider using the C# 2.0 yield operator:

IEnumerable<byte> Combine(byte[] a1, byte[] a2, byte[] a3)
{
    foreach (byte b in a1)
        yield return b;
    foreach (byte b in a2)
        yield return b;
    foreach (byte b in a3)
        yield return b;
}

JDO is dead

JDO is not dead actually so please check your facts. JDO 2.2 was released in Oct 2008 JDO 2.3 is under development.

This is developed openly, under Apache. More releases than JPA has had, and its ORM specification is still in advance of even the JPA2 proposed features

First Add a Class called Win32.cs

public class Win32
{ 
    [DllImport("User32.Dll")]
    public static extern long SetCursorPos(int x, int y);

    [DllImport("User32.Dll")]
    public static extern bool ClientToScreen(IntPtr hWnd, ref POINT point);

    [StructLayout(LayoutKind.Sequential)]
    public struct POINT
    {
        public int x;
        public int y;

        public POINT(int X, int Y)
        {
            x = X;
            y = Y;
        }
    }
}

You can use it then like this:

Win32.POINT p = new Win32.POINT(xPos, yPos);

Win32.ClientToScreen(this.Handle, ref p);
Win32.SetCursorPos(p.x, p.y);

Here's my late entry. I didn't like any of the others for various reasons, so I wrote my own.

This version features:

• Use of StringBuilder only. No ToArray() calls or other extension methods. It doesn't look as pretty as some of the other responses, but I consider this a core function so efficiency is more important than having "fluent", "one-liner" code which hide inefficiencies.

• Handles multiple values per key. (Didn't need it myself but just to silence Mauricio ;)

  public string ToQueryString(NameValueCollection nvc)
  {
      StringBuilder sb = new StringBuilder("?");
  
      bool first = true;
  
      foreach (string key in nvc.AllKeys)
      {
          foreach (string value in nvc.GetValues(key))
          {
              if (!first)
              {
                  sb.Append("&");
              }
  
              sb.AppendFormat("{0}={1}", Uri.EscapeDataString(key), Uri.EscapeDataString(value));
  
              first = false;
          }
      }
  
      return sb.ToString();
  }
  

Example Usage

        var queryParams = new NameValueCollection()
        {
            { "x", "1" },
            { "y", "2" },
            { "foo", "bar" },
            { "foo", "baz" },
            { "special chars", "? = &" },
        };

        string url = "http://example.com/stuff" + ToQueryString(queryParams);

        Console.WriteLine(url);

Output

http://example.com/stuff?x=1&y=2&foo=bar&foo=baz&special%20chars=%3F%20%3D%20%26

It's probably also worth mentioning that splice only works on arrays. (Object properties can't be relied on to follow a consistent order.)

To remove the key-value pair from an object, delete is actually what you want:

delete myObj.propName;     // , or:
delete myObj["propName"];  // Equivalent.

Spaces are used for separating Arguments. In your case C:\Program becomes argument. If your file path contains spaces then add Double quotation marks. Then cmd will recognize it as single argument.

To be honest, a ternary operator would only make this worse, what i would suggest if making it simpler is what you are aiming at is:

$groups = array(1=>"Player", 2=>"Gamemaster", 3=>"God");
echo($groups[$result->group_id]);

and then a similar one for your vocations

$vocations = array(
  1=>"Sorcerer",
  2=>"Druid",
  3=>"Paladin",
  4=>"Knight",
  ....
);
echo($vocations[$result->vocation]);

With a ternary operator, you would end up with

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Which as you can tell, only gets more complicated the more you add to it

If you want find one value from array, use Array#find:

arr = [1,2,6,4,9] 
arr.find {|e| e % 3 == 0}   #=>  6

See also:

arr.select {|e| e % 3 == 0} #=> [ 6, 9 ]
e.include? 6              #=> true

To find if a value exists in an Array you can also use #in? when using ActiveSupport. #in? works for any object that responds to #include?:

arr = [1, 6]
6.in? arr                 #=> true

A lot of applications (e.g. npm) can use proxy setting from user environment variables.

You can just add to your environment following variables HTTP_PROXY and HTTPS_PROXY that will have the same value for each one

http://user:password@proxyAddress:proxyPort

For example if you have Windows you can add proxy as follow:

Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)

Once you've generated your JSON, you can use something like the code below to POST it

StringRequestEntity requestEntity = new StringRequestEntity(
    JSON_STRING,
    "application/json",
    "UTF-8");

PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);

int statusCode = httpClient.executeMethod(postMethod);

Edit

Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:

StringEntity requestEntity = new StringEntity(
    JSON_STRING,
    ContentType.APPLICATION_JSON);

HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);

HttpResponse rawResponse = httpclient.execute(postMethod);

Your sheet is blank because your string writer in null. Here is what may help

System.Web.UI.HtmlTextWriter htmlWrite =
    new HtmlTextWriter(stringWrite);

    GridView1.RenderControl(htmlWrite);

Here is the full code

protected void Button1_Click(object sender, EventArgs e)
{
    Response.Clear();

    Response.AddHeader("content-disposition", "attachment;
    filename=FileName.xls");


    Response.ContentType = "application/vnd.xls";

    System.IO.StringWriter stringWrite = new System.IO.StringWriter();

    System.Web.UI.HtmlTextWriter htmlWrite =
    new HtmlTextWriter(stringWrite);

    GridView1.RenderControl(htmlWrite);

    Response.Write(stringWrite.ToString());

    Response.End();

}

Headers included with #include <> will be searched in all default directories , but you can also add your own location in the search path with -I command line arg.

I saw your edit you could install your headers in default locations usually

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

Confirm with compiler docs though.

I had the same problem - also make sure you add name="" in the input button. Well, that fix worked for me.

if($_SERVER['REQUEST_METHOD'] == 'POST' && !empty($_POST['add'])){
    echo "stuff is happening now";
}

<input type="submit" name="add" value="Submit">

const observable = of('response')

function hasValue(value: any) {
  return value !== null && value !== undefined;
}

function getValue<T>(observable: Observable<T>): Promise<T> {
  return observable
    .pipe(
      filter(hasValue),
      first()
    )
    .toPromise();
}

const result = await getValue(observable)
// Do the logic with the result
// .................
// .................
// .................

You can check the full article on how to implement it from here. https://www.imkrish.com/blog/development/simple-way-get-value-from-observable

Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class

  myObj:any = {
    doSomething: function () { console.log('doing something'); return 'doing something'; },
  };
  myArray:any;
  constructor() { }

  ngOnInit() {
    this.myArray = [this.myObj];
  }

You can use it in template html file as following:

<div>test-1: {{  myObj?.doSomething()}}</div>
<div>test-2: {{  myArray[0].doSomething()}}</div>
<div>test-3: {{  myArray[2]?.doSomething()}}</div>

The value you are setting in the timeout attribute is the one of the correct ways to set the session timeout value.

The timeout attribute specifies the number of minutes a session can be idle before it is abandoned. The default value for this attribute is 20.

By assigning a value of 1 to this attribute, you've set the session to be abandoned in 1 minute after its idle.

To test this, create a simple aspx page, and write this code in the Page_Load event,

Response.Write(Session.SessionID);

Open a browser and go to this page. A session id will be printed. Wait for a minute to pass, then hit refresh. The session id will change.

Now, if my guess is correct, you want to make your users log out as soon as the session times out. For doing this, you can rig up a login page which will verify the user credentials, and create a session variable like this -

Session["UserId"] = 1;

Now, you will have to perform a check on every page for this variable like this -

if(Session["UserId"] == null)
    Response.Redirect("login.aspx");

This is a bare-bones example of how this will work.

But, for making your production quality secure apps, use Roles & Membership classes provided by ASP.NET. They provide Forms-based authentication which is much more reliabletha the normal Session-based authentication you are trying to use.

Using some of the above recommendations, the following function and code is working for search a date range:

Set date with the time component set to 00:00:00

public static DateTime GetDateZeroTime(DateTime date)
{
    return new DateTime(date.Year, date.Month, date.Day, 0, 0, 0);
}

Usage

var modifieddatebegin = Tools.Utilities.GetDateZeroTime(form.modifieddatebegin);

var modifieddateend = Tools.Utilities.GetDateZeroTime(form.modifieddateend.AddDays(1));

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.
