(I tried previous answers but they lacks in some points. For example if you don't do a return; after finishing activity, remaining activity code runs. Also you need to edit onCreate with return. If you doesn't run super.onCreate() you will get a runtime error)

Say you have MainActivity and ChildActivity.

Inside ChildActivity add this:

Intent intent = new Intent(ChildActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);
return true;

Inside MainActivity's onCreate add this:

@Override
public void onCreate(Bundle savedInstanceState) {

    mContext = getApplicationContext();

    super.onCreate(savedInstanceState);

    if (getIntent().getBooleanExtra("EXIT", false)) {
        finish();
        return;
    }
    // your current codes
    // your current codes
}

In case someone wants to do it the other way around and finds this.

select convert(datetime, '12.09.2014', 104)

This converts a string in the German date format to a datetime object.

Why 104? See here: http://msdn.microsoft.com/en-us/library/ms187928.aspx

I don't know if something like that already exists. It would be easy to write your own with time, datetime and/or calendar modules, see http://docs.python.org/library/time.html

The only concern for a python solution is that your job needs to be always running and possibly be automatically "resurrected" after a reboot, something for which you do need to rely on system dependent solutions.

In SQL Server Management Studio 2016, perform the following:

• Right click on database

• Click delete

• Check close existing connections

• Perform delete operation

Android has its own method of printing messages (called logs) to the console, known as the LogCat.

When you want to print something to the LogCat, you use a Log object, and specify the category of message.

The main options are:

• DEBUG: Log.d
• ERROR: Log.e
• INFO: Log.i
• VERBOSE: Log.v
• WARN: Log.w

You print a message by using a Log statement in your code, like the following example:

Log.d("myTag", "This is my message");

Within Android Studio, you can search for log messages labelled myTag to easily find the message in the LogCat. You can also choose to filter logs by category, such as "Debug" or "Warn".

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

Your expression works if you add parentheses:

>>> y[(1 < x) & (x < 5)]
array(['o', 'o', 'a'], 
      dtype='|S1')

Does this answer your question?

I have never used reinterpret_cast, and wonder whether running into a case that needs it isn't a smell of bad design. In the code base I work on dynamic_cast is used a lot. The difference with static_cast is that a dynamic_cast does runtime checking which may (safer) or may not (more overhead) be what you want (see msdn).

In my case same error is there , I am using Asyanc / Await functions , for this needs to add AWAIT for findOne

Ex:const foundUser = User.findOne ({ "email" : req.body.email });

above , foundUser always contains Object value in both cases either user found or not because it's returning values before finishing findOne .

const foundUser = await User.findOne ({ "email" : req.body.email });

above , foundUser returns null if user is not there in collection with provided condition . If user found returns user document.

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

You can simply do this

$(function() {
    $( "#datepicker" ).datepicker({  maxDate: new Date });
  });

JSFiddle

FYI: while checking the documentation, found that it also accepts numeric values too.

Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.

so 0 represents today. Therefore you can do this too

 $( "#datepicker" ).datepicker({  maxDate: 0 });

In VS, right click your project, select "Add Reference...", and you will see all the namespaces that exist in your GAC. Choose Microsoft.SqlServer.Management.RegisteredServers and click OK, and you should be good to go

EDIT:

That is the way you want to do this most of the time. However, after a bit of poking around I found this issue on MS Connect. MS says it is a known deployment issue, and they don't have a work around. The guy says if he copies the dll from the GAC folder and drops it in his bin, it works.

If you have control over the HTML then you could add a real element instead of a pseudo one. :before and :after pseudo elements are rendered right after the open tag or right before the close tag. The inline equivalent for this css

td { text-align: justify; }
td:after { content: ""; display: inline-block; width: 100%; }

Would be something like this:

<table>
<tr>
<td style="text-align: justify;">
TD Content
<span class="inline_td_after" style="display: inline-block; width: 100%;"></span>
</td>
</tr>
</table>

Keep in mind; Your "real" before and after elements and anything with inline css will greatly increase the size of your pages and ignore page load optimizations that external css and pseudo elements make possible.

Which Boost library? Many of them are pure templates and do not require linking.

Now with that actually shown concrete example which tells us that you want Boost program options (and even more told us that you are on Ubuntu), you need to do two things:

1. Install libboost-program-options-dev so that you can link against it.
2. Tell cmake to link against libboost_program_options.

I mostly use Makefiles so here is the direct command-line use:

$ g++ boost_program_options_ex1.cpp -o bpo_ex1 -lboost_program_options
$ ./bpo_ex1
$ ./bpo_ex1 -h
$ ./bpo_ex1 --help
$ ./bpo_ex1 -help
$

It doesn't do a lot it seems.

For CMake, you need to add boost_program_options to the list of libraries, and IIRC this is done via SET(liblist boost_program_options) in your CMakeLists.txt.

You may want to take a different approach: Instead of changing the css dynamically, predefine your styles in CSS the way you want them. Then use JQuery to add and remove styles from within Javascript. (see code from Ajmal)

I had a similar exception (but different problem) - java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to org.bson.Document , and fortunately it's solved easier:

Instead of

List<Document> docs = obj.get("documents");
Document doc = docs.get(0)

which gives error on second line, One can use

List<Document> docs = obj.get("documents");
Document doc = new Document(docs.get(0));

Error message clearly says that source parameter is null. Source is the enumerable you are enumerating. In your case it is ListMetadataKor object. And its definitely null at the time you are filtering it second time. Make sure you never assign null to this list. Just check all references to this list in your code and look for assignments.

All you need to do for that is a simple loop.
This doesn't handle testing for lower case, upper-case mismatch. If this isn't exactly what you are looking for, comment, and I can revise.

data: {"csrfmiddlewaretoken" : "{{csrf_token}}"}

You see "403 (FORBIDDEN)", because you don`t send "csrfmiddlewaretoken" parameter. In template each form has this: {% csrf_token %}. You should add "csrfmiddlewaretoken" to your ajax data dictionary. My example is sending "product_code" and "csrfmiddlewaretoken" to app "basket" view "remove":

$(function(){
    $('.card-body').on('click',function(){
        $.ajax({
          type: "post",
          url: "{% url 'basket:remove'%}",
          data: {"product_code": "07316", "csrfmiddlewaretoken" : "{{csrf_token}}" }
        });
    })
});

iOS 11.x Swift 4.0 Info.plist needs these two properties

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>We're watching you</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Watch Out</string>

And this code ... making sure of course your a CLLocationManagerDelegate

let locationManager = CLLocationManager()

// MARK location Manager delegate code + more

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    switch status {
    case .notDetermined:
        print("User still thinking")
    case .denied:
        print("User hates you")
    case .authorizedWhenInUse:
            locationManager.stopUpdatingLocation()
    case .authorizedAlways:
            locationManager.startUpdatingLocation()
    case .restricted:
        print("User dislikes you")
    }

And of course this code too which you can put in viewDidLoad().

locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestLocation()

And these two for the requestLocation to get you going, aka save you having to get out of your seat :)

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
    print(error)
}

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    print(locations)
}

You can use the following code to check if a textbox object is null/empty

The biggest difference between Task.Delay and Thread.Sleep is that Task.Delay is intended to run asynchronously. It does not make sense to use Task.Delay in synchronous code. It is a VERY bad idea to use Thread.Sleep in asynchronous code.

Normally you will call Task.Delay() with the await keyword:

await Task.Delay(5000);

or, if you want to run some code before the delay:

var sw = new Stopwatch();
sw.Start();
Task delay = Task.Delay(5000);
Console.WriteLine("async: Running for {0} seconds", sw.Elapsed.TotalSeconds);
await delay;

Guess what this will print? Running for 0.0070048 seconds. If we move the await delay above the Console.WriteLine instead, it will print Running for 5.0020168 seconds.

Let's look at the difference with Thread.Sleep:

class Program
{
    static void Main(string[] args)
    {
        Task delay = asyncTask();
        syncCode();
        delay.Wait();
        Console.ReadLine();
    }

    static async Task asyncTask()
    {
        var sw = new Stopwatch();
        sw.Start();
        Console.WriteLine("async: Starting");
        Task delay = Task.Delay(5000);
        Console.WriteLine("async: Running for {0} seconds", sw.Elapsed.TotalSeconds);
        await delay;
        Console.WriteLine("async: Running for {0} seconds", sw.Elapsed.TotalSeconds);
        Console.WriteLine("async: Done");
    }

    static void syncCode()
    {
        var sw = new Stopwatch();
        sw.Start();
        Console.WriteLine("sync: Starting");
        Thread.Sleep(5000);
        Console.WriteLine("sync: Running for {0} seconds", sw.Elapsed.TotalSeconds);
        Console.WriteLine("sync: Done");
    }
}

Try to predict what this will print...

async: Starting
async: Running for 0.0070048 seconds
sync: Starting
async: Running for 5.0119008 seconds
async: Done
sync: Running for 5.0020168 seconds
sync: Done

Also, it is interesting to notice that Thread.Sleep is far more accurate, ms accuracy is not really a problem, while Task.Delay can take 15-30ms minimal. The overhead on both functions is minimal compared to the ms accuracy they have (use Stopwatch Class if you need something more accurate). Thread.Sleep still ties up your Thread, Task.Delay release it to do other work while you wait.

One of the major changes it seems is that with Android Studio the test application is integrated into the application project.

I'm not sure if this helps your specific problem, but I found a guide on making tests with a Gradle project. Android Gradle user Guide

Swift 4 and above: Inspired by anoop4real's solution, here's a String extension that can be used to generate text with 2 different colors.

extension String {

    func attributedStringForPartiallyColoredText(_ textToFind: String, with color: UIColor) -> NSMutableAttributedString {
        let mutableAttributedstring = NSMutableAttributedString(string: self)
        let range = mutableAttributedstring.mutableString.range(of: textToFind, options: .caseInsensitive)
        if range.location != NSNotFound {
            mutableAttributedstring.addAttribute(NSAttributedStringKey.foregroundColor, value: color, range: range)
        }
        return mutableAttributedstring
    }
}

Following example changes color of asterisk to red while retaining original label color for remaining text.

label.attributedText = "Enter username *".attributedStringForPartiallyColoredText("*", with: #colorLiteral(red: 1, green: 0, blue: 0, alpha: 1))

This example will exit after 5 seconds if another instance is already running.

// unique id for global mutex - Global prefix means it is global to the machine
const string mutex_id = "Global\\{B1E7934A-F688-417f-8FCB-65C3985E9E27}";

static void Main(string[] args)
{

    using (var mutex = new Mutex(false, mutex_id))
    {
        try
        {
            try
            {
                if (!mutex.WaitOne(TimeSpan.FromSeconds(5), false))
                {
                    Console.WriteLine("Another instance of this program is running");
                    Environment.Exit(0);
                }
            }
            catch (AbandonedMutexException)
            {
                // Log the fact the mutex was abandoned in another process, it will still get aquired
            }

            // Perform your work here.
        }
        finally
        {
            mutex.ReleaseMutex();
        }
    }
}

I have exactly the same problem. I haven't found a solution anywhere, but I have been able to fix it without rebooting by simply unmounting and remounting the mountpoint.

For your system the commands would be:

fusermount -uz /data
mount /data

The -z forces the unmount, which solved the need to reboot for me. You may need to do this as sudo depending on your setup. You may encounter the below error if the command does not have the required elevated permissions:

fusermount: entry for /data not found in /etc/mtab

I'm using Ubuntu 14.04 LTS, with the current version of mhddfs.

So performatic as the Sam Saffron's approach.

I like Aacini's response. I added to it to handle the day and also enable it to handle centiseconds (%TIME% outputs H:MM:SS.CC):

This is a common question, and I was heavily on the side wanting the ability to mock HttpClient, but I think I finally came to the realization that you shouldn't be mocking HttpClient. It seems logical to do so, but I think we've been brainwashed by things we see in open source libraries.

We often see "Clients" out there that we mock in our code so that we can test in isolation, so we automatically try to apply the same principle to HttpClient. HttpClient actually does a lot; you can think of it as a manager for HttpMessageHandler, so you don't wanna mock that, and that's why it still doesn't have an interface. The part that you're really interested in for unit testing, or designing your services, even, is the HttpMessageHandler since that is what returns the response, and you can mock that.

It's also worth pointing out that you should probably start treating HttpClient like a bigger deal. For example: Keep your instatiating of new HttpClients to a minimum. Reuse them, they're designed to be reused and use a crap ton less resources if you do. If you start treating it like a bigger deal, it'll feel much more wrong wanting to mock it and now the message handler will start to be the thing that you're injecting, not the client.

In other words, design your dependencies around the handler instead of the client. Even better, abstract "services" that use HttpClient which allow you to inject a handler, and use that as your injectable dependency instead. Then in your tests, you can fake the handler to control the response for setting up your tests.

Wrapping HttpClient is an insane waste of time.

Update: See Joshua Dooms's example. It's exactly what I'm recommending.

You are looking for size:

In [11]: df.groupby(['col5', 'col2']).size()
Out[11]:
col5  col2
1     A       1
      D       3
2     B       2
3     A       3
      C       1
4     B       1
5     B       2
6     B       1
dtype: int64

To get the same answer as waitingkuo (the "second question"), but slightly cleaner, is to groupby the level:

In [12]: df.groupby(['col5', 'col2']).size().groupby(level=1).max()
Out[12]:
col2
A       3
B       2
C       1
D       3
dtype: int64

you can only make circle from square using border-radius.

border-radius doesn't increase or reduce heights nor widths.

Your request is to use only image tag , it is basicly not possible if tag is not a square.

If you want to use a blank image and set another in bg, it is going to be painfull , one background for each image to set.

Cropping can only be done if a wrapper is there to do so. inthat case , you have many ways to do it

UPDATE tb_Company SET CompanyIndustry = UCASE(LEFT(CompanyIndustry, 1)) + 
SUBSTRING(CompanyIndustry, 2, LEN(CompanyIndustry))

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

SELECT TOP 1000 MAX(tel) FROM TableName WHERE Id IN

Just try beeprint

it prints something like this:

instance(Animal):
    legs: 2,
    name: 'Dog',
    color: 'Spotted',
    smell: 'Alot',
    age: 10,
    kids: 0,

I think is exactly what you need.

Hope this helps.

let number = 7;

if(number%2 == 0){      

  //do something;
  console.log('number is Even');  

}else{

  //do otherwise;
  console.log('number is Odd');

}

Here is a complete function that will log to the console the parity of your input.

const checkNumber = (x) => {
  if(number%2 == 0){      

    //do something;
    console.log('number is Even');  

  }else{

    //do otherwise;
    console.log('number is Odd');

  }
}

Here's a simple example of pretty printing JSON to the console in a nice way in Python, without requiring the JSON to be on your computer as a local file:

import pprint
import json 
from urllib.request import urlopen # (Only used to get this example)

# Getting a JSON example for this example 
r = urlopen("https://mdn.github.io/fetch-examples/fetch-json/products.json")
text = r.read() 

# To print it
pprint.pprint(json.loads(text))

Yet another 3rd party lib not mentioned here is mxDateTime (predecessor of both python datetime and 3rd party timeutil) could be used for this task.

The aforementioned yearsago would be:

from mx.DateTime import now, RelativeDateTime

def years_ago(years, from_date=None):
    if from_date == None:
        from_date = now()
    return from_date-RelativeDateTime(years=years)

First parameter is expected to be a DateTime instance.

To convert ordinary datetime to DateTime you could use this for 1 second precision):

def DT_from_dt_s(t):
    return DT.DateTimeFromTicks(time.mktime(t.timetuple()))

or this for 1 microsecond precision:

def DT_from_dt_u(t):
    return DT.DateTime(t.year, t.month, t.day, t.hour,
  t.minute, t.second + t.microsecond * 1e-6)

And yes, adding the dependency for this single task in question would definitely be an overkill compared even with using timeutil (suggested by Rick Copeland).

You can use "

On a system like OSX you might not have pgrep so you can try this appraoch, when looking for processes by name:

while ps axg | grep process_name$ > /dev/null; do sleep 1; done

The $ symbol at the end of the process name ensures that grep matches only process_name to the end of line in the ps output and not itself.

You can also use custom lib for that if you don't want to shake your real phone every 2 minutes

I've created a lib that allows you to use 3 fingers touch instead of shake to open dev menu, when in development mode

https://github.com/pie6k/react-native-dev-menu-on-touch

You only have to wrap your app inside:

import DevMenuOnTouch from 'react-native-dev-menu-on-touch'; // or: import { DevMenuOnTouch } from 'react-native-dev-menu-on-touch'

class YourRootApp extends Component {
  render() {
    return (
      <DevMenuOnTouch>
        <YourApp />
      </DevMenuOnTouch>
    );
  }
}

It's really useful when you have to debug on real device and you have co-workers sitting next to you.

(This explanation is only for positive numbers since it depends on the language otherwise)

Definition

The Modulus is the remainder of the euclidean division of one number by another. % is called the modulo operation.

For instance, 9 divided by 4 equals 2 but it remains 1. Here, 9 / 4 = 2 and 9 % 4 = 1.

In your example: 5 divided by 7 gives 0 but it remains 5 (5 % 7 == 5).

Calculation

The modulo operation can be calculated using this equation:

a % b = a - floor(a / b) * b

• floor(a / b) represents the number of times you can divide a by b
• floor(a / b) * b is the amount that was successfully shared entirely
• The total (a) minus what was shared equals the remainder of the division

Applied to the last example, this gives:

5 % 7 = 5 - floor(5 / 7) * 7 = 5

Modular Arithmetic

That said, your intuition was that it could be -2 and not 5. Actually, in modular arithmetic, -2 = 5 (mod 7) because it exists k in Z such that 7k - 2 = 5.

You may not have learned modular arithmetic, but you have probably used angles and know that -90° is the same as 270° because it is modulo 360. It's similar, it wraps! So take a circle, and say that it's perimeter is 7. Then you read where is 5. And if you try with 10, it should be at 3 because 10 % 7 is 3.

This is a simple solution that worked for me with the same problem (I think): mv /var/lib/mongodb /var/lib/mongodb_backup mkdir /var/lib/mongodb chmod 700 /var/lib/mongodb chown mongodb:daemon /var/lib/mongodb systemctl restart mongodb or service mongod restart

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

My module memory_profiler is capable of printing a line-by-line report of memory usage and works on Unix and Windows (needs psutil on this last one). Output is not very detailed but the goal is to give you an overview of where the code is consuming more memory, not an exhaustive analysis on allocated objects.

After decorating your function with @profile and running your code with the -m memory_profiler flag it will print a line-by-line report like this:

Line #    Mem usage  Increment   Line Contents
==============================================
     3                           @profile

     6    166.20 MB  152.59 MB       b = [2] * (2 * 10 ** 7)
     7     13.61 MB -152.59 MB       del b

function Rand7
   put 200 into x
   repeat while x > 118
      put ((random(5)-1) * 25) + ((random(5)-1) * 5) + (random(5)-1) into x
   end repeat
   return (x mod 7) + 1
end Rand7

Three calls to Rand5, which only repeats 6 times out of 125, on average.

Think of it as a 3D array, 5x5x5, filled with 1 to 7 over and over, and 6 blanks. Re-roll on the blanks. The rand5 calls create a three digit base-5 index into that array.

There would be fewer repeats with a 4D, or higher N-dimensional arrays, but this means more calls to the rand5 function become standard. You'll start to get diminishing efficiency returns at higher dimensions. Three seems to me to be a good compromise, but I haven't tested them against each other to be sure. And it would be rand5-implementation specific.

• Match letters only /[A-Z]/ig
• Match anything not letters /[^A-Z]/ig
• Match number only /[0-9]/g or /\d+/g
• Match anything not number /[^0-9]/g or /\D+/g
• Match anything not number or letter /[^A-Z0-9]/ig

There are other possible patterns

You could just write it out in multiline like this,

$ cat dict.go
package main

import "fmt"

func main() {
        items := map[string]interface{}{
                "foo": map[string]int{
                        "strength": 10,
                        "age": 2000,
                },
                "bar": map[string]int{
                        "strength": 20,
                        "age": 1000,
                },
        }
        for key, value := range items {
                fmt.Println("[", key, "] has items:")
                for k,v := range value.(map[string]int) {
                        fmt.Println("\t-->", k, ":", v)
                }

        }
}

And the output:

$ go run dict.go
[ foo ] has items:
        --> strength : 10
        --> age : 2000
[ bar ] has items:
        --> strength : 20
        --> age : 1000

Ctrl+F gives me Find/Replace dialog box.

Or you can,

First Alt+A

Next Alt+F

Then press on Replace button.

If non of them worked:

Goto -> Window -> Preferences -> General -> Keys and search for replace then you will see binding for Find and replace. In the bottom of that window, you can add your key to Binding text box. There you can add or edit any keys as shortcut.

The basic idea will be using a nested query with count aggregation:

select * from yourTable ou
where (select count(*) from yourTable inr
where inr.sid = ou.sid) > 1

You can adjust the where clause in the inner query to narrow the search.

There is another good solution for that mentioned in the comments, (but not everyone reads them):

select Column1, Column2, count(*)
from yourTable
group by Column1, Column2
HAVING count(*) > 1

Or shorter:

SELECT (yourTable.*)::text, count(*)
FROM yourTable
GROUP BY yourTable.*
HAVING count(*) > 1

Kurts answer needed to be slightly modified to work for me.

First, on ubuntu: sudo apt-get install python-imaging

Then:

from PIL import Image
im=Image.open(filepath)
im.size # (width,height) tuple

You can use the DataGridViewCell.Value Property to retrieve the value stored in a particular cell.

So to retrieve the value of the 'first' selected Cell and display in a MessageBox, you can:

MessageBox.Show(dataGridView1.SelectedCells[0].Value.ToString());

The above probably isn't exactly what you need to do. If you provide more details we can provide better help.

This is another option:

export default function Counter() {

}

A dictionary is something like an array that's accessed by keys (e.g. strings,...) rather than just plain sequential numbers. It contains key/value pairs, you can look up values using a key like using a phone book: key=name, number=value.

For defining such a dictionary, you use this syntax using curly braces, see also: http://wiki.python.org/moin/SimplePrograms

When I first started working with PDF, I found the PDF reference very hard to navigate. It might help you to know that the overview of the file structure is found in syntax, and what Adobe call the document structure is the object structure and not the file structure. That is also found in Syntax. The description of operators is hidden away in Appendix A - very useful for understanding what is happening in content streams. If you ever have the pain of working with colour spaces you will find that hidden in Graphics! Hopefully these pointers will help you find things more quickly than I did.

If you are using windows, pdftron CosEdit allows you to browse the object structure to understand it. There is a free demo available that allows you to examine the file but not save it.

System.out.println(pageCrawling.getHtmlFromURL("http://ipecho.net/plain"));

Normally I use selenium, which is software for testing automation. You can control a browser through a webdriver, so you will not have problems with javascripts and it is usually not very detected if you use the full version. Headless browsers can be more identified.

If the buffer is full, all strings that is buffered on it, they will be saved onto the disk. Buffers is used for avoiding from Big Deals! and overhead.

In BufferedWriter class that is placed in java libs, there is a one line like:

private static int defaultCharBufferSize = 8192;

If you do want to send data before the buffer is full, you do have control. Just Flush It. Calls to writer.flush() say, "send whatever's in the buffer, now!

You can use this regular expression:

^(2[0-3]|[01]?[0-9]):([1-5]{1}[0-9])$

If you want to exclude 00:00, you can use this expression

^(2[0-3]|[01]?[0-9]):(0[1-9]{1}|[1-5]{1}[0-9])$

Second expression is better option because valid time is 00:01 to 00:59 or 0:01 to 23:59. You can use any of these upon your requirement. Regex101 link

Try this one:

try
{
    device_version =  getPackageManager().getPackageInfo("com.google.android.gms", 0).versionName;
}
catch (PackageManager.NameNotFoundException e)
{
    e.printStackTrace();
}

You can use just:

"{0:b}".format(n)

In my opinion this is the easiest way!

This can work as well.

Use HashBytes

SELECT HashBytes('MD5', '[email protected]')

That will give you 0xF53BD08920E5D25809DF2563EF9C52B6

-

SELECT CONVERT(NVARCHAR(32),HashBytes('MD5', '[email protected]'),2)

That will give you F53BD08920E5D25809DF2563EF9C52B6

$.each(top_brands, function(index, el) {
  for (var key in el) {
    if (el.hasOwnProperty(key)) {
         brand_options.append($("<option />").val(key).text(key+ " "  + el[key]));
    }
  }
});

But if your data structure is var top_brands = {'Adidas': 100, 'Nike': 50};, then thing will be much more simple.

for (var key in top_brands) {
  if (top_brands.hasOwnProperty(key)) {
       brand_options.append($("<option />").val(key).text(key+ " "  + el[key]));
  }
}

Or use the jquery each:

$.each(top_brands, function(key, value) {
    brand_options.append($("<option />").val(key).text(key + " "  + value));
});

I believe, the usage of and the difference between Factory & Builder patterns can be understood/clarified easier in a certain time period as you worked on the same code base and changing requirements.

From my experience, usually, you start with a Factory pattern including couple of static creator methods to primarily hide away relatively complex initialisation logic. As your object hierarchy gets more complex (or as you add more types, parameters), you probably end up having your methods populated with more parameters and not to mention you gonna have to recompile your Factory module. All those stuff, increases the complexity of your creator methods, decreases the readability and makes the creation module more fragile.

This point possibly will be the transition/extension point. By doing so, you create a wrapper module around the construction parameters and then you will be able represent new (similar) objects by adding some more abstractions(perhaps) and implementations without touching actual your creation logic. So you've had "less" complex logic.

Frankly, referring to something sort of "having an object created in one-step or multiple steps is the difference" as the sole diversity factor was not sufficient for me to distinguish them since I could use both ways for almost all cases I faced up to now without experiencing any benefit. So this is what I've finally thought about it.

array[index] == 'undefined' compares the value of the array index to the string "undefined".
You're probably looking for typeof array[index] == 'undefined', which compares the type.

New to Eclipse and Android development and this hung me up for quite a while. Here's a few things I was doing wrong that may help someone in the future:

1. I was downloading code examples and assuming project name would be the same as the folder name and was looking for that folder name in the project explorer, not finding it, re-importing it, then getting the error message it already existed in the workspace. Yeah. Not proud of that.
2. Didn't click on 'Copy projects into Workspace' and then searched in vain through the workspace when it didn't appear in the project explorer BECAUSE
3. The 'Add project to working sets' option in the Import Projects tab isn't working as far as I can tell, so was not appearing in the project explorer for the active working set (refresh made no difference). Adding project to the working set had to be done after successfully importing it.

For those wondering what EXACTLY needs to be done to keep rows selected even as you scroll up down. It's the state_activated The rest is taken care of by internal functionality, you don't have to worry about toggle, and can select multiple items. I didn't need to use notifyDataSetChanged() or setSelected(true) methods.

Add this line to your selector file, for me drawable\row_background.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@android:color/holo_blue_light"/>

    <item android:state_enabled="true" android:state_pressed="true" android:drawable="@android:color/holo_blue_light" />
    <item android:state_enabled="true" android:state_focused="true" android:drawable="@android:color/holo_blue_bright" />
    <item android:state_enabled="true" android:state_selected="true" android:drawable="@android:color/holo_blue_light" />
    <item android:state_activated="true" android:drawable="@android:color/holo_blue_light" />

    <item android:drawable="@android:color/transparent"/>
</selector>

Then in layout\custom_row.xml

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding="10dip"
        android:background="@drawable/row_background"
        android:orientation="vertical">
  <TextView
        android:id="@+id/line1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

For more information, I'm using this with ListView Adapter, using myList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL); and myList.setMultiChoiceModeListener(new MultiChoiceModeListener()...

from this example: http://www.androidbegin.com/tutorial/android-delete-multiple-selected-items-listview-tutorial/

Also, you (should) use this structure for your list-adapter coupling: List myList = new ArrayList();

instead of: ArrayList myList = new ArrayList();

Explanation: Type List vs type ArrayList in Java

Open up your git bash and type

echo $HOME

This shall be the same folder as you get when you open your command window (cmd) and type

echo %USERPROFILE%

And – of course – the .ssh folder shall be present on THAT directory.

I encountered the same error while using SpringBoot 2.1.4, along with Spring Security 5 (I believe). After one day of trying everything that Google had to offer, I discovered the cause of error in my case. I had a setup of micro-services, with the Auth server being different from the Resource Server. I had the following lines in my application.yml which prevented 'auto-configuration' despite of having included dependencies spring-boot-starter-security, spring-security-oauth2 and spring-security-jwt. I had included the following in the properties (during development) which caused the error.

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Commenting it out solved it for me.

#spring:
#  autoconfigure:
#    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Hope, it helps someone.

mysql_real_escape_string() or str_replace() function will help you to solve your problem.

Use [] notation for string representations of properties:

console.log(obj[name]);

Otherwise it's looking for the "name" property, rather than the "a" property.

$sql = "select count(*) as row from login WHERE firstname = '" . $username . "' AND password = '" . $password . "'";
    $query = $this->db->query($sql);
    print_r($query);exit;
    if ($query->num_rows() == 1) {
    return true;
    } else {
    return false;
    }

It seems you don't import jquery. Those $ functions come with this non standard (but very useful) library.

Read the tutorial there : http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery It starts with how to import the library.

datediff(to_date(String timestamp), to_date(String timestamp))

For example:

SELECT datediff(to_date('2019-08-03'), to_date('2019-08-01')) <= 2;

You can use the name property for that particular element. For example to set a border of 2px around an input element with name xyz, you can use;

$(function() {
    $("input[name = 'xyz']").css("border","2px solid red");
})

DEMO

(function(){
    var i = 0;
    function stop(){
        clearTimeout(i);
    }

    function start(){
        i = setTimeout( timed, 1000 );
    }

    function timed(){
       document.getElementById("input").value++;
       start();
    }

    window.stop = stop;
    window.start = start;
})()

Jenkins is a service account, it doesn't have a shell by design. It is generally accepted that service accounts. shouldn't be able to log in interactively.

To resolve "Jenkins Host key verification failed", do the following steps. I have used mercurial with jenkins.

1)Execute following commands on terminal

             $ sudo su -s /bin/bash jenkins

provide password

2)Generate public private key using the following command:

              ssh-keygen

you can see output as ::

Generating public/private rsa key pair. 
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 

3)Press Enter --> Do not give any passphrase--> press enter

             Key has been generated

4) go to --> cat /var/lib/jenkins/.ssh/id_rsa.pub

5) Copy key from id_rsa.pub

6)Exit from bash

7) ssh@yourrepository

8) vi .ssh/authorized_keys

9) Paste the key

10) exit

11)Manually login to mercurial server

Note: Pls do manually login otherwise jenkins will again give error "host verification failed"

12)once manually done, Now go to Jenkins and give build

Enjoy!!!

Good Luck

The following works for me:

function decodeHtml(html) {
    let areaElement = document.createElement("textarea");
    areaElement.innerHTML = html;

    return areaElement.value;
}

It's a reference to the current object, it's most commonly used in object oriented code.

• Reference: http://www.php.net/manual/en/language.oop5.basic.php
• Primer: http://www.phpro.org/tutorials/Object-Oriented-Programming-with-PHP.html

Example:

<?php
class Person {
    public $name;

    function __construct( $name ) {
        $this->name = $name;
    }
};

$jack = new Person('Jack');
echo $jack->name;

This stores the 'Jack' string as a property of the object created.

Another one in v11:

select CURRENT APPLICATION COMPATIBILITY from sysibm.sysdummy1

Result:

V11R1

It's not the current version, but the current configured level for the application.

This answer has been updated to reflect latest stable angularjs version. One important note is that $cookieStore is a thin wrapper surrounding $cookies. They are pretty much the same in that they only work with session cookies. Although, this answers the original question, there are other solutions you may wish to consider such as using localstorage, or jquery.cookie plugin (which would give you more fine-grained control and do serverside cookies. Of course doing so in angularjs means you probably would want to wrap them in a service and use $scope.apply to notify angular of changes to models (in some cases).

One other note and that is that there is a slight difference between the two when pulling data out depending on if you used $cookie to store value or $cookieStore. Of course, you'd really want to use one or the other.

In addition to adding reference to the js file you need to inject ngCookies into your app definition such as:

angular.module('myApp', ['ngCookies']);

you should then be good to go.

Here is a functional minimal example, where I show that cookieStore is a thin wrapper around cookies:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
   <link rel="stylesheet" type="text/css" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
</head>
<body ng-controller="MyController">

  <h3>Cookies</h3>
  <pre>{{usingCookies|json}}</pre>
  <h3>Cookie Store</h3>
  <pre>{{usingCookieStore|json}}</pre>

  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular-cookies.js"></script>
  <script>
    angular.module('myApp', ['ngCookies']);
    app.controller('MyController',['$scope','$cookies','$cookieStore', 
                       function($scope,$cookies,$cookieStore) {
      var someSessionObj = { 'innerObj' : 'somesessioncookievalue'};

    $cookies.dotobject = someSessionObj;
    $scope.usingCookies = { 'cookies.dotobject' : $cookies.dotobject, "cookieStore.get" : $cookieStore.get('dotobject') };

    $cookieStore.put('obj', someSessionObj);
    $scope.usingCookieStore = { "cookieStore.get" : $cookieStore.get('obj'), 'cookies.dotobject' : $cookies.obj, };
    }
  </script>

</body>
</html>

The steps are:

1. include angular.js
2. include angular-cookies.js
3. inject ngCookies into your app module (and make sure you reference that module in the ng-app attribute)
4. add a $cookies or $cookieStore parameter to the controller
5. access the cookie as a member variable using the dot (.) operator -- OR --
6. access cookieStore using put/get methods

The Basics

Look at these to build a solution more or less from scratch:

• Start from the basics: The Java Tutorial's chapter on Networking, including Working With URLs
• Make things easier for yourself: Apache HttpComponents (including HttpClient)

The Easily Glued-Up and Stitched-Up Stuff

You always have the option of calling external tools from Java using the exec() and similar methods. For instance, you could use wget, or cURL.

The Hardcore Stuff

Then if you want to go into more fully-fledged stuff, thankfully the need for automated web-testing as given us very practical tools for this. Look at:

• HtmlUnit (powerful and simple)
• Selenium, Selenium-RC
• WebDriver/Selenium2 (still in the works)
• JBehave with JBehave Web

Some other libs are purposefully written with web-scraping in mind:

• JSoup
• Jaunt

Some Workarounds

Java is a language, but also a platform, with many other languages running on it. Some of which integrate great syntactic sugar or libraries to easily build scrapers.

Check out:

• Groovy (and its XmlSlurper)
• or Scala (with great XML support as presented here and here)

If you know of a great library for Ruby (JRuby, with an article on scraping with JRuby and HtmlUnit) or Python (Jython) or you prefer these languages, then give their JVM ports a chance.

Some Supplements

Some other similar questions:

• Scrape data from HTML using Java
• Options for HTML Scraping

Parenthesis is not required to instantiate a class object when you don't intend to use a parameterised constructor.

Just use Foo foo2;

It will work.

Python Extension. From the Python Docs:

The solution chosen by the Perl developers was to use (?...) as the extension syntax. ? immediately after a parenthesis was a syntax error because the ? would have nothing to repeat, so this didn’t introduce any compatibility problems. The characters immediately after the ? indicate what extension is being used, so (?=foo) is one thing (a positive lookahead assertion) and (?:foo) is something else (a non-capturing group containing the subexpression foo).

Python supports several of Perl’s extensions and adds an extension syntax to Perl’s extension syntax.If the first character after the question mark is a P, you know that it’s an extension that’s specific to Python

https://docs.python.org/3/howto/regex.html

You could write a custom template filter to do this in a half-dozen lines of code:

from django.template import Library

register = Library()

@register.filter
def is_false(arg): 
    return arg is False

Then in your template:

{% if myvar|is_false %}...{% endif %}

Of course, you could make that template tag much more generic... but this suits your needs specifically ;-)

These are use in ruby on rails :-

<% %> :-

The <% %> tags are used to execute Ruby code that does not return anything, such as conditions, loops or blocks. Eg :-

<h1>Names of all the people</h1>
<% @people.each do |person| %>
  Name: <%= person.name %><br>
<% end %>

<%= %> :-

use to display the content .

Name: <%= person.name %><br>

<% -%>:-

Rails extends ERB, so that you can suppress the newline simply by adding a trailing hyphen to tags in Rails templates

<%# %>:-

comment out the code

<%# WRONG %>
Hi, Mr. <% puts "Frodo" %>

The file is created automatically (talking about Xcode 6.3.2 here). But you won't see it, since it's in your Derived Data folder. After marking your swift class with @objc, compile, then search for Swift.h in your Derived Data folder. You should find the Swift header there.

I had the problem, that Xcode renamed my my-Project-Swift.h to my_Project-Swift.h Xcode doesn't like "." "-" etc. symbols. With the method above you can find the filename and import it to a Objective-C class.

Follow below steps:

• 1. Ensure to delete all the contents of the jar folder located in your local except the jar that you want to keep.
     For example files like .repositories, .pom, .sha1, .lastUpdated etc.
• 2. Execute mvn clean install -o command

This will help to use local repository jar files rather than connecting to any repository.

here is the correct way of using proxy along with creds..

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);

IWebProxy proxy = request.Proxy;                    
if (proxy != null)
{
    Console.WriteLine("Proxy: {0}", proxy.GetProxy(request.RequestUri));
}
else
{
    Console.WriteLine("Proxy is null; no proxy will be used");
}

Thanks everyone for help... :)

This is a great question and I was surprised at how difficult it was to find a clear and complete answer, most of the answers I found were either sudo-code or not 100% complete.

I was able to create a complete solution to copy and save the data from my DataGridView to an excel file based on Jake's answer so I'm posting my complete solution in the hopes that it can help other new comers to c# like myself :)

First off, you will need the Microsoft.Office.Interop.Excel reference in your project. See MSDN on how to add it.

My Code:

using Excel = Microsoft.Office.Interop.Excel;

private void btnExportToExcel_Click(object sender, EventArgs e)
{
    SaveFileDialog sfd = new SaveFileDialog();
    sfd.Filter = "Excel Documents (*.xls)|*.xls";
    sfd.FileName = "Inventory_Adjustment_Export.xls";
    if (sfd.ShowDialog() == DialogResult.OK)
    {
        // Copy DataGridView results to clipboard
        copyAlltoClipboard();

        object misValue = System.Reflection.Missing.Value;
        Excel.Application xlexcel = new Excel.Application();

        xlexcel.DisplayAlerts = false; // Without this you will get two confirm overwrite prompts
        Excel.Workbook xlWorkBook = xlexcel.Workbooks.Add(misValue);
        Excel.Worksheet xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

        // Format column D as text before pasting results, this was required for my data
        Excel.Range rng = xlWorkSheet.get_Range("D:D").Cells;
        rng.NumberFormat = "@";

        // Paste clipboard results to worksheet range
        Excel.Range CR = (Excel.Range)xlWorkSheet.Cells[1, 1];
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);

        // For some reason column A is always blank in the worksheet. ¯\_(?)_/¯
        // Delete blank column A and select cell A1
        Excel.Range delRng = xlWorkSheet.get_Range("A:A").Cells;
        delRng.Delete(Type.Missing);
        xlWorkSheet.get_Range("A1").Select();

        // Save the excel file under the captured location from the SaveFileDialog
        xlWorkBook.SaveAs(sfd.FileName, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
        xlexcel.DisplayAlerts = true;
        xlWorkBook.Close(true, misValue, misValue);
        xlexcel.Quit();

        releaseObject(xlWorkSheet);
        releaseObject(xlWorkBook);
        releaseObject(xlexcel);

        // Clear Clipboard and DataGridView selection
        Clipboard.Clear();
        dgvItems.ClearSelection();

        // Open the newly saved excel file
        if (File.Exists(sfd.FileName))
            System.Diagnostics.Process.Start(sfd.FileName);
    }
}

private void copyAlltoClipboard()
{
    dgvItems.SelectAll();
    DataObject dataObj = dgvItems.GetClipboardContent();
    if (dataObj != null)
        Clipboard.SetDataObject(dataObj);
}

private void releaseObject(object obj)
{
    try
    {
        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
        obj = null;
    }
    catch (Exception ex)
    {
        obj = null;
        MessageBox.Show("Exception Occurred while releasing object " + ex.ToString());
    }
    finally
    {
        GC.Collect();
    }
}

Seaborn box plot returns a matplotlib axes instance. Unlike pyplot itself, which has a method plt.title(), the corresponding argument for an axes is ax.set_title(). Therefore you need to call

sns.boxplot('Day', 'Count', data= gg).set_title('lalala')

A complete example would be:

import seaborn as sns
import matplotlib.pyplot as plt

tips = sns.load_dataset("tips")
sns.boxplot(x=tips["total_bill"]).set_title("LaLaLa")

plt.show()

Of course you could also use the returned axes instance to make it more readable:

ax = sns.boxplot('Day', 'Count', data= gg)
ax.set_title('lalala')
ax.set_ylabel('lololo')

class Program
{
    static void Main(string[] args)
    {
        string returnValue = null;
       new Thread(
          () =>
          {
              returnValue =test() ; 
          }).Start();
        Console.WriteLine(returnValue);
        Console.ReadKey();
    }

    public static string test()
    {
        return "Returning From Thread called method";
    }
}

Set variable "a" to some value like this,

a=0;

Declaring and initialzing are both different.

Good Luck

This is a slightly enhanced version of previous answers.

• In addition to Lawrence's answer, it cancels the original task when timeout occurs.
• In addtion to sjb's answer variants 2 and 3, you can provide CancellationToken for the original task, and when timeout occurs, you get TimeoutException instead of OperationCanceledException.

async Task<TResult> CancelAfterAsync<TResult>(
    Func<CancellationToken, Task<TResult>> startTask,
    TimeSpan timeout, CancellationToken cancellationToken)
{
    using (var timeoutCancellation = new CancellationTokenSource())
    using (var combinedCancellation = CancellationTokenSource
        .CreateLinkedTokenSource(cancellationToken, timeoutCancellation.Token))
    {
        var originalTask = startTask(combinedCancellation.Token);
        var delayTask = Task.Delay(timeout, timeoutCancellation.Token);
        var completedTask = await Task.WhenAny(originalTask, delayTask);
        // Cancel timeout to stop either task:
        // - Either the original task completed, so we need to cancel the delay task.
        // - Or the timeout expired, so we need to cancel the original task.
        // Canceling will not affect a task, that is already completed.
        timeoutCancellation.Cancel();
        if (completedTask == originalTask)
        {
            // original task completed
            return await originalTask;
        }
        else
        {
            // timeout
            throw new TimeoutException();
        }
    }
}

Usage

InnerCallAsync may take a long time to complete. CallAsync wraps it with a timeout.

async Task<int> CallAsync(CancellationToken cancellationToken)
{
    var timeout = TimeSpan.FromMinutes(1);
    int result = await CancelAfterAsync(ct => InnerCallAsync(ct), timeout,
        cancellationToken);
    return result;
}

async Task<int> InnerCallAsync(CancellationToken cancellationToken)
{
    return 42;
}

1. Add the file to your project.
2. Go to the Properties of that file.
3. Set "Build Action" to Embedded Resource.
4. Set "Copy to Output Directory" to Copy Always.

As of PowerShell 6.0, Split-Path has an -Extenstion parameter. This means you can do:

$path | Split-Path -Extension

or

Split-Path -Path $path -Extension

For $path = "test.txt" both versions will return .txt, inluding the full stop.

I have slightly modified Ilya_Gazman answer to use new APIs (IntentCompat is deprecated starting API 26). Runtime.getRuntime().exit(0) seems to be better than System.exit(0).

 public static void triggerRebirth(Context context) {
    PackageManager packageManager = context.getPackageManager();
    Intent intent = packageManager.getLaunchIntentForPackage(context.getPackageName());
    ComponentName componentName = intent.getComponent();
    Intent mainIntent = Intent.makeRestartActivityTask(componentName);
    context.startActivity(mainIntent);
    Runtime.getRuntime().exit(0);
}

First method: You could use "+" sign for concatenating strings, but this always happens in print. Another way: The String class includes a method for concatenating two strings: string1.concat(string2);

GregorianCalendar c = GregorianCalendar.from((LocalDate.parse("2016-06-22")).atStartOfDay(ZoneId.systemDefault()));
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

    <li><a href="javascript:void"><i class="fa fa-plus-circle"></i>Category 1</a>

            <li><a href="javascript:void">item 2</a></li>

//Jquery

$(document).ready(function() {
    $('li').click(function() {
      $('i').toggleClass('fa-plus-square fa-minus-square');
    });
  }); 

JSFiddle

This three lines of code can remove the duplicated element from ArrayList or any collection.

List<Entity> entities = repository.findByUserId(userId);

Set<Entity> s = new LinkedHashSet<Entity>(entities);
entities.clear();
entities.addAll(s);

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

public List<Student> findStudentByReports(Date startDate, Date endDate) {
    System.out.println("call findStudentMethd******************with this pattern"
                    + startDate
                    + endDate
                    + "*********************************************");

    return em
            .createQuery(
                    "' select attendence from Attendence attendence where attendence.admissionDate BETWEEN : startDate '' AND endDate ''"
                            + "'")
            .setParameter("startDate", startDate, TemporalType.DATE)
            .setParameter("endDate", endDate, TemporalType.DATE)
            .getResultList();

}

If you need to order your code into namespaces, just use the keyword namespace:

file1.php

namespace foo\bar;

In file2.php

$obj = new \foo\bar\myObj();

You can also use use. If in file2 you put

use foo\bar as mypath;

you need to use mypath instead of bar anywhere in the file:

$obj  = new mypath\myObj();

Using use foo\bar; is equal to use foo\bar as bar;.

Debian Linux (e.g. Ubuntu)

sudo apt-get update
OpenGL: sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

Windows

Locate your Visual Studio folder for where it puts libraries and also header files, download and copy lib files to lib folder and header files to header. Then copy dll files to system32. Then your code will 100% run.

Also Windows: For all of those includes you just need to download glut32.lib, glut.h, glut32.dll.

For what it's worth, let's say you wanted to resize the view in device independent pixels (dp): -

You need to use a method called applyDimension, that's a member of the class TypedValue to convert from dp to pixels. So if I want to set the height to 150dp (say) - then I could do this:

float pixels = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 150, getResources().getDisplayMetrics());
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) someLayout.getLayoutParams();
params.height = (int) pixels;
someLayout.setLayoutParams(params);

where the expression: getResources().getDisplayMetrics() gets the screen density/resolution

You can pip install pickle by running command pip install pickle-mixin. Proceed to import it using import pickle. This can be then used normally.

Generate a number in the range from 100000 to 999999.

// pseudo code
int n = 100000 + random_float() * 900000;

The best way to process command line arguments is the argparse module.

Use raw_input() to get user input. If you import the readline module your users will have line editing and history.

In your html

<table class="table1">
<tr>
<td>
...
</table>

<table class="table2">

<tr>
<td>
...
</table>

In your css:

table.table1 {...}
table.table1 tr {...}
table.table1 td {...}

table.table2 {...}
table.table2 tr {...}
table.table2 td {...}

jsFunction is not in good closure. change to:

jsFunction = function(value)
{
    alert(value);
}

and don't use global variables and functions, change it into module

1. To disable the beep in bash you need to uncomment (or add if not already there) the line set bell-style none in your /etc/inputrc file.

   Note: Since it is a protected file you need to be a privileged user to edit it (i.e. launch your text editor with something like sudo <editor> /etc/inputrc).

2. To disable the beep also in vim you need to add set visualbell in your ~/.vimrc file.

3. To disable the beep also in less (i.e. also in man pages and when using "git diff") you need to add export LESS="$LESS -R -Q" in your ~/.profile file.

If you still face error in sending email, with the same error message. Try this:

$mail->SMTPSecure = 'tls';
$mail->Host = 'smtp.gmail.com';

just Before the line:

$send = $mail->Send();

or in other sense, before calling the Send() Function.

Tested and Working.

These answers do help explain this, but it still isn't perfectly intuitive for a non-programmer (i.e. someone like me who is learning Python for the first time in context of data science coursework). I still find using the terms "along" or "for each" wrt to rows and columns to be confusing.

What makes more sense to me is to say it this way:

• Axis 0 will act on all the ROWS in each COLUMN
• Axis 1 will act on all the COLUMNS in each ROW

So a mean on axis 0 will be the mean of all the rows in each column, and a mean on axis 1 will be a mean of all the columns in each row.

Ultimately this is saying the same thing as @zhangxaochen and @Michael, but in a way that is easier for me to internalize.

I solved this issue by adding apiVersion inside AWS.S3(), then it works perfectly for S3 signed url.

Change from

var s3 = new AWS.S3();

to

var s3 = new AWS.S3({apiVersion: '2006-03-01'});

For more detailed examples, can refer to this AWS Doc SDK Example: https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/javascript/example_code/s3/s3_getsignedurl.js

Just put here some useful comment made by Jonathan Watt to drop all tables

MYSQL="mysql -h HOST -u USERNAME -pPASSWORD DB_NAME"
$MYSQL -BNe "show tables" | awk '{print "set foreign_key_checks=0; drop table `" $1 "`;"}' | $MYSQL
unset MYSQL

It helps me and I hope it could be useful

This is the code I'm using to embed images into HTML mail and PDF documents.

<?php
$logo_path = 'http://localhost/img/logo.jpg';
$type = pathinfo($logo_path, PATHINFO_EXTENSION);
$image_contents = file_get_contents($logo_path);
$image64 = 'data:image/' . $type . ';base64,' . base64_encode($image_contents);

echo '<img src="' . $image64 .'" />';
?>

The specific value in your database isn't what you should be focusing on. This is likely the result of an attacker fuzzing your system to see if it is vulnerable to a set of standard attacks, instead of a targeted attack exploiting a known vulnerability.

You should instead focus on ensuring that your application is secure against these types of attacks; OWASP is a good resource for this.

If you're using parameterized queries to access the database, then you're secure against Sql injection, unless you're using dynamic Sql in the backend as well.

If you're not doing this, you're vulnerable and you should resolve this immediately.

Also, you should consider performing some sort of validation of e-mail addresses.

I'm going to suggest the non-obvious. There is a fantastic (and often under-used) tool called the Immediate Window in Visual Basic Editor. Basically, you can write out commands in VBA and execute them on the spot, sort of like command prompt. It's perfect for cases like this.

Press ALT+F11 to open VBE, then Control+G to open the Immediate Window. Type the following and hit enter:

for each v in range("K2:K5000") : v.value = "'" & v.value : next

And boom! You are all done. No need to create a macro, declare variables, no need to drag and copy, etc. Close the window and get back to work. The only downfall is to undo it, you need to do it via code since VBA will destroy your undo stack (but that's simple).

You can extract all the information from the DbEntityValidationException with the following code (you need to add the namespaces: System.Data.Entity.Validation and System.Diagnostics to your using list):

catch (DbEntityValidationException dbEx)
{
    foreach (var validationErrors in dbEx.EntityValidationErrors)
    {
        foreach (var validationError in validationErrors.ValidationErrors)
        {
            Trace.TraceInformation("Property: {0} Error: {1}", 
                                    validationError.PropertyName, 
                                    validationError.ErrorMessage);
        }
    }
}

To clarify, you should use HTTP error codes where they fit with the protocol, and not use HTTP status codes to send business logic errors.

Errors like insufficient balance, no cabs available, bad user/password qualify for HTTP status 200 with application specific error handling in the response body.

See this software engineering answer:

I would say it is better to be explicit about the separation of protocols. Let the HTTP server and the web browser do their own thing, and let the app do its own thing. The app needs to be able to make requests, and it needs the responses--and its logic as to how to request, how to interpret the responses, can be more (or less) complex than the HTTP perspective.

You can check the local and global value of it with:

SELECT @@SQL_MODE, @@GLOBAL.SQL_MODE;

I copied some code and created a TC. Basically converted a normal java class to JUnit TC. I was gettgig error. Later I created a new JUnit Class from New -> Junit TC. Copied the same code. It works fine and error vanished.

Mongo shell command that worked for me:

db.getCollection(<collection_name>).aggregate([{"$match": {'<key>': '<value to match>'}}, {"$group": {'_id': {'<group_by_attribute>': "$group_by_attribute"}}}])

Unbelievably, in 3 years nobody has answered your excellent question with examples of both ways to map the relationship.

As mentioned by others, the "owner" side contains the pointer (foreign key) in the database. You can designate either side as the owner, however, if you designate the One side as the owner, the relationship will not be bidirectional (the inverse aka "many" side will have no knowledge of its "owner"). This can be desirable for encapsulation/loose coupling:

// "One" Customer owns the associated orders by storing them in a customer_orders join table
public class Customer {
    @OneToMany(cascade = CascadeType.ALL)
    private List<Order> orders;
}

// if the Customer owns the orders using the customer_orders table,
// Order has no knowledge of its Customer
public class Order {
    // @ManyToOne annotation has no "mappedBy" attribute to link bidirectionally
}

The only bidirectional mapping solution is to have the "many" side own its pointer to the "one", and use the @OneToMany "mappedBy" attribute. Without the "mappedBy" attribute Hibernate will expect a double mapping (the database would have both the join column and the join table, which is redundant (usually undesirable)).

// "One" Customer as the inverse side of the relationship
public class Customer {
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "customer")
    private List<Order> orders;
}

// "many" orders each own their pointer to a Customer
public class Order {
    @ManyToOne
    private Customer customer;
}

Although I'm sure this won't be accepted as the answer to this very old question, I came here looking for a way to do this and this is how I solved the problem.

I created a demonstration here at codepen.io.

</div>
<div class="difference">The timer is set to go off <span></span></div>
<div class="countdown"></div>

The Javascript:

var now = moment(); // new Date().getTime();
var then = moment().add(60, 'seconds'); // new Date(now + 60 * 1000);

$(".now").text(moment(now).format('h:mm:ss a'));
$(".then").text(moment(then).format('h:mm:ss a'));
$(".duration").text(moment(now).to(then));
(function timerLoop() {
  $(".difference > span").text(moment().to(then));
  $(".countdown").text(countdown(then).toString());
  requestAnimationFrame(timerLoop);
})();

Output:

The time is now: 5:29:35 pm, a timer will go off in a minute at 5:30:35 pm
The timer is set to go off in a minute
1 minute

Note: 2nd line above updates as per momentjs and 3rd line above updates as per countdownjs and all of this is animated at about ~60FPS because of requestAnimationFrame()

Requirements:

• CountdownJS: http://countdownjs.org/ (And Rawgit to be able to use countdownjs)
• MomentJS: http://momentjs.com/
• requestAnimationFrame() - use this for animation rather than setInterval().

Optional Requirements:

• jQuery: https://jquery.com/

Additionally here is some light reading about the requestAnimationFrame() pattern:

• http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
• https://css-tricks.com/using-requestanimationframe/

I found the requestAnimationFrame() pattern to be much a more elegant solution than the setInterval() pattern.

The best practice is definitely to avoid loops or recursions in Matlab.

Between sum(A(:)) and sum(sum(A)). In my experience, arrays in Matlab seems to be stored in a continuous block in memory as stacked column vectors. So the shape of A does not quite matter in sum(). (One can test reshape() and check if reshaping is fast in Matlab. If it is, then we have a reason to believe that the shape of an array is not directly related to the way the data is stored and manipulated.)

As such, there is no reason sum(sum(A)) should be faster. It would be slower if Matlab actually creates a row vector recording the sum of each column of A first and then sum over the columns. But I think sum(sum(A)) is very wide-spread amongst users. It is likely that they hard-code sum(sum(A)) to be a single loop, the same to sum(A(:)).

Below I offer some testing results. In each test, A=rand(size) and size is specified in the displayed texts.

First is using tic toc.

They seem equivalent. Either one is good. But sum(sum(A)) requires that you know the dimension of your array is 2.

for me the following commands worked:

$ brew install mysql

$ brew services start mysql

Your last one was almost there:

trait A {
    function calc($v) {
        return $v+1;
    }
}

class MyClass {
    use A {
        calc as protected traitcalc;
    }

    function calc($v) {
        $v++;
        return $this->traitcalc($v);
    }
}

The trait is not a class. You can't access its members directly. It's basically just automated copy and paste...

To disable inputting password:

sudo visudo

Then add a new line like below and save then:

# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer

Then you run installer without password:

sudo installer -pkg ...

You can achieve this by using the following query:

EXEC sp_msforeachdb 
    'IF EXISTS
    (
        SELECT  1 
        FROM    [?].sys.objects 
        WHERE   name LIKE ''OBJECT_TO_SEARCH''
    )
    SELECT 
        ''?''       AS DB, 
        name        AS Name, 
        type_desc   AS Type 
    FROM [?].sys.objects 
    WHERE name LIKE ''OBJECT_TO_SEARCH'''

Just replace OBJECT_TO_SEARCH with the actual object name you are interested in (or part of it, surrounded with %).

I had a workaround for this problem. I created dll project with viewer in vs2015 and used this dll in vs2017. Report showing perfectly.

You can directly write the array in modern Java, without an initializer. Your example is now valid. It is generally best to name the parameter anyway.

String[] array = {"blah", "hey", "yo"};

or

int[] array = {1, 2, 3};

If you have to inline, you'll need to declare the type:

functionCall(new String[]{"blah", "hey", "yo"});

or use varargs (variable arguments)

void functionCall(String...stringArray) {
    // Becomes a String[] containing any number of items or empty
}

functionCall("blah", "hey", "yo");

Hopefully Java's developers will allow implicit initialization in the future

Update: Kotlin Answer

Kotlin has made working with arrays so much easier! For most types, just use arrayOf and it will implicitly determine type. Pass nothing to leave them empty.

arrayOf("1", "2", "3") // String
arrayOf(1, 2, 3)       // Int
arrayOf(1, 2, "foo")   // Any 
arrayOf<Int>(1, 2, 3)  // Set explict type
arrayOf<String>()      // Empty String array

Primitives have utility functions. Pass nothing to leave them empty.

intArrayOf(1, 2, 3)
charArrayOf()
booleanArrayOf()
longArrayOf()
shortArrayOf()
byteArrayOf()

If you already have a Collection and wish to convert it to an array inline, simply use:

collection.toTypedArray()

If you need to coerce an array type, use:

array.toIntArray()
array.toLongArray()
array.toCharArray()
...

Though asynchronous style may be the nature of node.js and generally you should not do this, there are some times you want to do this.

I'm writing a handy script to check an API and want not to mess it up with callbacks.

Javascript cannot execute synchronous requests, but C libraries can.

If we can assume that the H1 is always going to be there, then

div h1+div {...}

but don't be afraid to specify the id of the content div:

#content h1+div {...}

That's about as good as you can get cross-browser right now without resorting to a JavaScript library like jQuery. Using h1+div ensures that only the first div after the H1 gets the style. There are alternatives, but they rely on CSS3 selectors, and thus won't work on most IE installs.

Try this in your styles.xml:

colorPrimary will be the toolbar color.

<resources>

<style name="AppTheme" parent="Theme.AppCompat">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_pressed</item>
    <item name="colorAccent">@color/accent</item>
</style>

Did you build this in Eclipse by the way?

Just to summerize .

If your app is being loaded from external links then angular wont detect this as a URL change so $loaction.search() would give you an empty object . To solve this you need to set following in your app config(app.js)

.config(['$routeProvider', '$locationProvider', function ($routeProvider,     $locationProvider) 
{
   $routeProvider
      .when('/', {
         templateUrl: 'views/main.html',
         controller: 'MainCtrl'
      })
      .otherwise({
         redirectTo: '/'
      });

      $locationProvider.html5Mode(true);
 }]);

This should work without converting to List/Array:

collectionName.stream().reduce((prev, next) -> next).orElse(null)

You might find this Wikipedia article on salting worthwhile. The idea is to add a set bit of data to randomize your hash value; this will protect your passwords from dictionary attacks if someone gets unauthorized access to the password hashes.

As mentioned in multiple answers above you can import the cURL in POSTMAN directly. But if URL is authorized (or is not working for some reason) ill suggest you can manually add all the data points as JSON in your postman body. take the API URL from the cURL.

for the Authorization part- just add an Authorization key and base 64 encoded string as value.

example:

curl -u rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a \ https://api.razorpay.com/v1/orders -X POST \ --data "amount=50000" \ --data "currency=INR" \ --data "receipt=Receipt #20" \ --data "payment_capture=1" https://api.razorpay.com/v1/orders

{ "amount": "5000", "currency": "INR", "receipt": "Receipt #20", "payment_capture": "1" }

Headers: Authorization:Basic cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J where "cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J" is the encoded form of "rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a"`

small tip: for encoding, you can easily go to your chrome console (right-click => inspect) and type : btoa("string you want to encode") ( or use postman basic authorization)

See this page: http://www.oracle.com/technetwork/articles/javase/index-140767.html

It has a slightly different pattern which is (I think) what you are looking for:

try {
  mutex.acquire();
  try {
    // do something
  } finally {
    mutex.release();
  }
} catch(InterruptedException ie) {
  // ...
}

In this usage, you're only calling release() after a successful acquire()

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

This should work fine:

your_command 2>&1 | tee -a file.txt

It will store all logs in file.txt as well as dump them on terminal.

You can create your file under any directory you want. After creation, you can "tell" the path to mysql config:

EDIT: Consider looking at and upvoting Malvineous's answer on this page. Netmasks are a much more elegant solution.

Simply use a percent sign as a wildcard in the IP address.

From http://dev.mysql.com/doc/refman/5.1/en/grant.html

You can specify wildcards in the host name. For example, user_name@'%.example.com' applies to user_name for any host in the example.com domain, and user_name@'192.168.1.%' applies to user_name for any host in the 192.168.1 class C subnet.

Work-Break has nothing to do with inline-block.

Make sure you specify width and notice if there are any overriding attributes in parent nodes. Make sure there is not white-space: nowrap.

  <style scoped>
    .parent {

    }

    p {

      padding: 1em;
      font-size: calc(0.6vw + 0.6em);
      direction: ltr;

      hyphens: auto;
    }


    }
  </style>
  <div class="parent">

    <p>
      Note: Mind that, as for now, break-word is not part of the standard specification for webkit; therefore, you might be interested in employing the break-all instead. This alternative value provides a undoubtedly drastic solution; however, it conforms to
      the standard.

Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.

First considerations are about mixing HTML, Javascript and CSS:

Why is using onClick() in HTML a bad practice?

Unobtrusive Javascript

Inline Styles vs Classes

I will be removing inline content and splitting these into their appropriate files.

Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.

Your function changeBackground sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.

CSS

#TheForm {
    margin-left: 396px;
}
#submitColor {
    margin-left: 48px;
    margin-top: 5px;
}

HTML

<form id="TheForm">
    <input id="color" type="text" />
    <br/>
    <input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>

Javascript

function changeBackground() {
    var color = document.getElementById("color").value; // cached

    // The working function for changing background color.
    document.bgColor = color;

    // The code I'd like to use for changing the text simultaneously - however it does not work.
    document.getElementById("coltext").style.color = color;
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

Color Values

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.

Update: as pointed out by @Ian

Hex can be either 3 or 6 characters long

Source: W3C

Numerical color values

The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.

Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.

For regex testing, I will use this pattern

/^#(?:[0-9a-f]{3}){1,2}$/i

but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern

function changeBackground() {
    var color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;

    if (rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Hex Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

Here is a further modification that will allow colours by name along with by hex.

function changeBackground() {
    var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
        color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
        formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();

    if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Color");
    }

How can we read data from a text file and store in a String Variable?

Err, read data from the file and store it in a String variable. It's just code. Not a real question so far.

Is it possible to pass the filename in a method and it would return the String which is the text from the file.

Yes it's possible. It's also a very bad idea. You should deal with the file a part at a time, for example a line at a time. Reading the entire file into memory before you process any of it adds latency; wastes memory; and assumes that the entire file will fit into memory. One day it won't. You don't want to do it this way.

You need enctype="multipart/form-data" otherwise you will load only the file name and not the data.

I have successfully used as shown below in Jenkinsfile:

steps {
  script {
    def reportPath = "${WORKSPACE}/target/report"
    ...
  }
}

This happened to me when I was on develop branch and my master branch is not with latest update.

So when I tried to git push from develop branch I had that error.

I fixed it by switching to master branch, git pull, then go back to develop branch and git push.

$ git fetch && git checkout master
$ git pull
$ git fetch && git checkout develop
$ git push

Styling checkboxes (and many other input elements for that mater) is not really possible with pure css if you want to drastically change the visual appearance.

Your best bet is to implement something like jqTransform does which actually replaces you inputs with images and applies javascript behaviour to it to mimic a checkbox (or other element for that matter)

A LEFT JOIN is absolutely not faster than an INNER JOIN. In fact, it's slower; by definition, an outer join (LEFT JOIN or RIGHT JOIN) has to do all the work of an INNER JOIN plus the extra work of null-extending the results. It would also be expected to return more rows, further increasing the total execution time simply due to the larger size of the result set.

(And even if a LEFT JOIN were faster in specific situations due to some difficult-to-imagine confluence of factors, it is not functionally equivalent to an INNER JOIN, so you cannot simply go replacing all instances of one with the other!)

Most likely your performance problems lie elsewhere, such as not having a candidate key or foreign key indexed properly. 9 tables is quite a lot to be joining so the slowdown could literally be almost anywhere. If you post your schema, we might be able to provide more details.

Edit:

Reflecting further on this, I could think of one circumstance under which a LEFT JOIN might be faster than an INNER JOIN, and that is when:

• Some of the tables are very small (say, under 10 rows);
• The tables do not have sufficient indexes to cover the query.

Consider this example:

CREATE TABLE #Test1
(
    ID int NOT NULL PRIMARY KEY,
    Name varchar(50) NOT NULL
)
INSERT #Test1 (ID, Name) VALUES (1, 'One')
INSERT #Test1 (ID, Name) VALUES (2, 'Two')
INSERT #Test1 (ID, Name) VALUES (3, 'Three')
INSERT #Test1 (ID, Name) VALUES (4, 'Four')
INSERT #Test1 (ID, Name) VALUES (5, 'Five')

CREATE TABLE #Test2
(
    ID int NOT NULL PRIMARY KEY,
    Name varchar(50) NOT NULL
)
INSERT #Test2 (ID, Name) VALUES (1, 'One')
INSERT #Test2 (ID, Name) VALUES (2, 'Two')
INSERT #Test2 (ID, Name) VALUES (3, 'Three')
INSERT #Test2 (ID, Name) VALUES (4, 'Four')
INSERT #Test2 (ID, Name) VALUES (5, 'Five')

SELECT *
FROM #Test1 t1
INNER JOIN #Test2 t2
ON t2.Name = t1.Name

SELECT *
FROM #Test1 t1
LEFT JOIN #Test2 t2
ON t2.Name = t1.Name

DROP TABLE #Test1
DROP TABLE #Test2

If you run this and view the execution plan, you'll see that the INNER JOIN query does indeed cost more than the LEFT JOIN, because it satisfies the two criteria above. It's because SQL Server wants to do a hash match for the INNER JOIN, but does nested loops for the LEFT JOIN; the former is normally much faster, but since the number of rows is so tiny and there's no index to use, the hashing operation turns out to be the most expensive part of the query.

You can see the same effect by writing a program in your favourite programming language to perform a large number of lookups on a list with 5 elements, vs. a hash table with 5 elements. Because of the size, the hash table version is actually slower. But increase it to 50 elements, or 5000 elements, and the list version slows to a crawl, because it's O(N) vs. O(1) for the hashtable.

But change this query to be on the ID column instead of Name and you'll see a very different story. In that case, it does nested loops for both queries, but the INNER JOIN version is able to replace one of the clustered index scans with a seek - meaning that this will literally be an order of magnitude faster with a large number of rows.

So the conclusion is more or less what I mentioned several paragraphs above; this is almost certainly an indexing or index coverage problem, possibly combined with one or more very small tables. Those are the only circumstances under which SQL Server might sometimes choose a worse execution plan for an INNER JOIN than a LEFT JOIN.

Do you mean like this?

>>> mystring = "This isn't the right place to have \"'\" (single quotes)"
>>> mystring
'This isn\'t the right place to have "\'" (single quotes)'
>>> newstring = mystring.replace("'", "")
>>> newstring
'This isnt the right place to have "" (single quotes)'

On iOS, it currently does not matter if you use int or NSInteger. It will matter more if/when iOS moves to 64-bits.

Simply put, NSIntegers are ints in 32-bit code (and thus 32-bit long) and longs on 64-bit code (longs in 64-bit code are 64-bit wide, but 32-bit in 32-bit code). The most likely reason for using NSInteger instead of long is to not break existing 32-bit code (which uses ints).

CGFloat has the same issue: on 32-bit (at least on OS X), it's float; on 64-bit, it's double.

Update: With the introduction of the iPhone 5s, iPad Air, iPad Mini with Retina, and iOS 7, you can now build 64-bit code on iOS.

Update 2: Also, using NSIntegers helps with Swift code interoperability.

My workaround had been using gnu sed. Worked fine for my purposes.

You can use setTimeout():

var addBg = function(e) {_x000D_
  e = e || window.event;_x000D_
  e.preventDefault();_x000D_
  var el = e.target || e.srcElement;_x000D_
  el.className = 'bg';_x000D_
  setTimeout(function() {_x000D_
    removeBg(el);_x000D_
  }, 10 * 1000); //<-- (in miliseconds)_x000D_
};_x000D_
_x000D_
var removeBg = function(el) {_x000D_
  el.className = '';_x000D_
};

div {_x000D_
  border: 1px solid grey;_x000D_
  padding: 5px 7px;_x000D_
  display: inline-block;_x000D_
  margin: 5px;_x000D_
}_x000D_
.bg {_x000D_
  background: orange;_x000D_
}

<body onclick='addBg(event);'>This is body_x000D_
  <br/>_x000D_
  <div onclick='addBg(event);'>This is div_x000D_
  </div>_x000D_
</body>

Using jQuery:

var addBg = function(e) {_x000D_
  e.stopPropagation();_x000D_
  var el = $(this);_x000D_
  el.addClass('bg');_x000D_
  setTimeout(function() {_x000D_
    removeBg(el);_x000D_
  }, 10 * 1000); //<-- (in miliseconds)_x000D_
};_x000D_
_x000D_
var removeBg = function(el) {_x000D_
  $(el).removeClass('bg');_x000D_
};_x000D_
_x000D_
$(function() {_x000D_
  $('body, div').on('click', addBg);_x000D_
});

div {_x000D_
  border: 1px solid grey;_x000D_
  padding: 5px 7px;_x000D_
  display: inline-block;_x000D_
  margin: 5px;_x000D_
}_x000D_
.bg {_x000D_
  background: orange;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<body>This is body_x000D_
  <br/>_x000D_
  <div>This is div</div>_x000D_
</body>

This can also be done with the Image class of the PIL library:

from PIL import Image
import numpy as np

im_frame = Image.open(path_to_file + 'file.png')
np_frame = np.array(im_frame.getdata())

Note: The .getdata() might not be needed - np.array(im_frame) should also work

you can use raiserror. Read more details here

--from MSDN

BEGIN TRY
    -- RAISERROR with severity 11-19 will cause execution to 
    -- jump to the CATCH block.
    RAISERROR ('Error raised in TRY block.', -- Message text.
               16, -- Severity.
               1 -- State.
               );
END TRY
BEGIN CATCH
    DECLARE @ErrorMessage NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState INT;

    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();

    -- Use RAISERROR inside the CATCH block to return error
    -- information about the original error that caused
    -- execution to jump to the CATCH block.
    RAISERROR (@ErrorMessage, -- Message text.
               @ErrorSeverity, -- Severity.
               @ErrorState -- State.
               );
END CATCH;

EDIT If you are using SQL Server 2012+ you can use throw clause. Here are the details.

If you do not have an LDF file then:

1) put the MDF in the C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\

2) In ssms, go to Databases -> Attach and add the MDF file. It will not let you add it this way but it will tell you the database name contained within.

3) Make sure the user you are running ssms.exe as has acccess to this MDF file.

4) Now that you know the DbName, run

EXEC sp_attach_single_file_db @dbname = 'DbName', 
@physname = N'C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\yourfile.mdf';

Reference: https://dba.stackexchange.com/questions/12089/attaching-mdf-without-ldf

So the answer seems to be to NOT use the Solution Explorer search box.

Rather, open any file in the solution, then use the control-f search pop-up to search all files by:

1. selecting "Find All" from the "--> Find Next / <-- Find Previous" selector
2. selecting "Current Project" or "Entire Solution" from the selector that normally says just "Current Document".

@Naftule - with "defiant.js", it is possible to query a JSON structure with XPath expressions. Check out this evaluator to get an idea of how it works:

http://www.defiantjs.com/#xpath_evaluator

Unlike JSONPath, "defiant.js" delivers the full-scale support of the query syntax - of XPath on JSON structures.

The source code of defiant.js can be found here:
https://github.com/hbi99/defiant.js

You can pass an instance of java.lang.Class that represents the type, i.e.

private void foo(Class cls)

word is on the stack and goes out of scope as soon as getStr() returns. You are invoking undefined behavior.

The best practice and Best OneLiner:

df.to_csv(newformat,header=1)

Notice the header value:

Header refer to the Row number(s) to use as the column names. Make no mistake, the row number is not the df but from the excel file(0 is the first row, 1 is the second and so on).

This way, you will get the column name you want and won't have to write additional codes or create new df.

Good thing is, it drops the replaced row.

Try this jsfiddle. This is using jQuery and made from Hashem Qolami's answer. At first, make a regular table then make it scrollable.

const makeScrollableTable = function (tableSelector, tbodyHeight) {
  let $table = $(tableSelector);
  let $bodyCells = $table.find('tbody tr:first').children();
  let $headCells = $table.find('thead tr:first').children();
  let headColWidth = 0;
  let bodyColWidth = 0;
  
  headColWidth = $headCells.map(function () {
    return $(this).outerWidth();
  }).get();
  bodyColWidth = $bodyCells.map(function () {
    return $(this).outerWidth();
  }).get();

  $table.find('thead tr').children().each(function (i, v) {
    $(v).css("width", headColWidth[i]+"px");
    $(v).css("min-width", headColWidth[i]+"px");
    $(v).css("max-width", headColWidth[i]+"px");
  });
  $table.find('tbody tr').children().each(function (i, v) {
    $(v).css("width", bodyColWidth[i]+"px");
    $(v).css("min-width", bodyColWidth[i]+"px");
    $(v).css("max-width", bodyColWidth[i]+"px");
  });

  $table.find('thead').css("display", "block");
  $table.find('tbody').css("display", "block");

  $table.find('tbody').css("height", tbodyHeight+"px");
  $table.find('tbody').css("overflow-y", "auto");
  $table.find('tbody').css("overflow-x", "hidden");
  
};

Then you can use this function as follows:

makeScrollableTable('#test-table', 250);

$ens = $em->getRepository('AcmeBinBundle:Marks')
              ->findBy(
                 array(), 
                 array('id' => 'ASC')
               );

There are at least three places where you may find shared_ptr:

1. If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in <memory>.

2. If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will likely be in <memory> (Microsoft Visual C++) or <tr1/memory> (g++'s libstdc++). Boost also provides a TR1 implementation that you can use.

3. Otherwise, you can obtain the Boost libraries and use boost::shared_ptr, which can be found in <boost/shared_ptr.hpp>.

Service is a Context

In case anyone needs a nullable result and for this to work across Enums, PropertyInfo and classes, here's how I solved it. This is a modification of Darin Dimitrov's updated solution.

public static object GetAttributeValue<TAttribute, TValue>(this object val, Func<TAttribute, TValue> valueSelector) where TAttribute : Attribute
{
    try
    {
        Type t = val.GetType();
        TAttribute attr;
        if (t.IsEnum && t.GetField(val.ToString()).GetCustomAttributes(typeof(TAttribute), true).FirstOrDefault() is TAttribute att)
        {
            // Applies to Enum values
            attr = att;
        }
        else if (val is PropertyInfo pi && pi.GetCustomAttributes(typeof(TAttribute), true).FirstOrDefault() is TAttribute piAtt)
        {
            // Applies to Properties in a Class
            attr = piAtt;
        }
        else
        {
            // Applies to classes
            attr = (TAttribute)t.GetCustomAttributes(typeof(TAttribute), false).FirstOrDefault();
        }
        return valueSelector(attr);
    }
    catch
    {
        return null;
    }
}

Usage examples:

// Class
SettingsEnum.SettingGroup settingGroup = (SettingsEnum.SettingGroup)(this.GetAttributeValue((SettingGroupAttribute attr) => attr.Value) as SettingsEnum.SettingGroup?);

// Enum
DescriptionAttribute desc = settingGroup.GetAttributeValue((DescriptionAttribute attr) => attr) as DescriptionAttribute;

// PropertyInfo       
foreach (PropertyInfo pi in this.GetType().GetProperties())
{
    string setting = ((SettingsEnum.SettingName)(pi.GetAttributeValue((SettingNameAttribute attr) => attr.Value) as SettingsEnum.SettingName?)).ToString();
}

(more of a functional note)

There are cases when you have to use GROUP BY, for example if you wanted to get the number of employees per employer:

SELECT u.employer, COUNT(u.id) AS "total employees" FROM users u GROUP BY u.employer

In such a scenario DISTINCT u.employer doesn't work right. Perhaps there is a way, but I just do not know it. (If someone knows how to make such a query with DISTINCT please add a note!)

Matlab code of two methods that have been published in highly regarded journals (IEEE Transactions on Image Processing) are available here: https://ivulab.asu.edu/software

check the CPBDM and JNBM algorithms. If you check the code it's not very hard to be ported and incidentally it is based on the Marzialiano's method as basic feature.

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

It could be caused by wrong version, you can double check the parent's version and lib's version, to make sure they're correct and not duplicated, I've experienced same problem

If you have:

int i = 10;
int x = ++i;

then x will be 11.

But if you have:

int i = 10;
int x = i++;

then x will be 10.

Note as Eric points out, the increment occurs at the same time in both cases, but it's what value is given as the result that differs (thanks Eric!).

Generally, I like to use ++i unless there's a good reason not to. For example, when writing a loop, I like to use:

for (int i = 0; i < 10; ++i) {
}

Or, if I just need to increment a variable, I like to use:

++x;

Normally, one way or the other doesn't have much significance and comes down to coding style, but if you are using the operators inside other assignments (like in my original examples), it's important to be aware of potential side effects.

Taken from

Regular Expression HOWTO

span() returns both start and end indexes in a single tuple. Since the match method only checks if the RE matches at the start of a string, start() will always be zero. However, the search method of RegexObject instances scans through the string, so the match may not start at zero in that case.

>>> p = re.compile('[a-z]+')
>>> print p.match('::: message')
None
>>> m = p.search('::: message') ; print m
<re.MatchObject instance at 80c9650>
>>> m.group()
'message'
>>> m.span()
(4, 11)

Combine that with:

In Python 2.2, the finditer() method is also available, returning a sequence of MatchObject instances as an iterator.

>>> p = re.compile( ... )
>>> iterator = p.finditer('12 drummers drumming, 11 ... 10 ...')
>>> iterator
<callable-iterator object at 0x401833ac>
>>> for match in iterator:
...     print match.span()
...
(0, 2)
(22, 24)
(29, 31)

you should be able to do something on the order of

for match in re.finditer(r'[a-z]', 'a1b2c3d4'):
   print match.span()

Set the CommandText as well, and call Fill on the SqlAdapter to retrieve the results in a DataSet:

var con = new SqlConnection();
con.ConnectionString = "connection string";
var com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "sp_returnTable";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);

(Example is using parameterless constructors for clarity; can be shortened by using other constructors.)

Things to know in general:

1. Key != Password
   • SecretKeySpec expects a key, not a password. See below
2. It might be due to a policy restriction that prevents using 32 byte keys. See other answer on that

In your case

The problem is number 1: you are passing the password instead of the key.

AES only supports key sizes of 16, 24 or 32 bytes. You either need to provide exactly that amount or you derive the key from what you type in.

There are different ways to derive the key from a passphrase. Java provides a PBKDF2 implementation for such a purpose.

I used erickson's answer to paint a complete picture (only encryption, since the decryption is similar, but includes splitting the ciphertext):

SecureRandom random = new SecureRandom();
byte[] salt = new byte[16];
random.nextBytes(salt);

KeySpec spec = new PBEKeySpec("password".toCharArray(), salt, 65536, 256); // AES-256
SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] key = f.generateSecret(spec).getEncoded();
SecretKeySpec keySpec = new SecretKeySpec(key, "AES");

byte[] ivBytes = new byte[16];
random.nextBytes(ivBytes);
IvParameterSpec iv = new IvParameterSpec(ivBytes);

Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
c.init(Cipher.ENCRYPT_MODE, keySpec, iv);
byte[] encValue = c.doFinal(valueToEnc.getBytes());

byte[] finalCiphertext = new byte[encValue.length+2*16];
System.arraycopy(ivBytes, 0, finalCiphertext, 0, 16);
System.arraycopy(salt, 0, finalCiphertext, 16, 16);
System.arraycopy(encValue, 0, finalCiphertext, 32, encValue.length);

return finalCiphertext;

Other things to keep in mind:

• Always use a fully qualified Cipher name. AES is not appropriate in such a case, because different JVMs/JCE providers may use different defaults for mode of operation and padding. Use AES/CBC/PKCS5Padding. Don't use ECB mode, because it is not semantically secure.
• If you don't use ECB mode then you need to send the IV along with the ciphertext. This is usually done by prefixing the IV to the ciphertext byte array. The IV is automatically created for you and you can get it through cipherInstance.getIV().
• Whenever you send something, you need to be sure that it wasn't altered along the way. It is hard to implement a encryption with MAC correctly. I recommend you to use an authenticated mode like CCM or GCM.

ctrl + w, w as mentioned can be used for navigating from pane to pane.

Now you can select a particular change alone and paste it to the other pane as follows.Here I am giving an eg as if I wanted to change my piece of code from pane 1 to pane 2 and currently my cursor is in pane1

• Use Shift-v to highlight a line and use up or down keys to select the piece of code you require and continue from step 3 written below to paste your changes in the other pane.

• Use visual mode and then change it

  1 click 'v' this will take you to visual mode 2 use up or down key to select your required code 3 click on ,Esc' escape key 4 Now use 'yy' to copy or 'dd' to cut the change 5 do 'ctrl + w, w' to navigate to pane2 6 click 'p' to paste your change where you require
