When you set the spinner background color using android:background="@color/your_color" your spinner default arrow will disappear

And also need to add fixed width and height to spinner so you can show the full content of the spinner.

so i found a way to do it , just like the above image.

Write your spinner code inside a frame layout, here you don't need to use a separate image view for showing drop down icon.

  <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Floor"
            android:textColor="@color/white"/>

        <FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="@dimen/margin_short"
            android:background="@drawable/custom_spn_background">

            <Spinner
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:dropDownSelector="@color/colorAccent"
                android:dropDownWidth="@dimen/dp_70"
                android:spinnerMode="dropdown"
                android:tooltipText="Select floor" />
        </FrameLayout>

Create a new xml for Frame layout background or set android:background="@color/your_color"

custom_spn_background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="@dimen/dp_5" />
<solid android:color="@color/white" />

First line in the List API says it is an ordered collection (also known as a sequence). If you sort the list you can't maintain the order, so there is no TreeList in Java.
As API says Java List got inspired from Sequence and see the sequence properties http://en.wikipedia.org/wiki/Sequence_(mathematics)

It doesn't mean that you can't sort the list, but Java strict to his definition and doesn't provide sorted versions of lists by default.

If you execute your Spring Boot application as a linux service (e.g. init.d script or similar), then you have the following option as well: Create a file called yourApplication.conf and put it next to your executable war/jar file. It's content should be something similar:

JAVA_OPTS="
-Djavax.net.ssl.trustStore=path-to-your-trustStore-file
-Djavax.net.ssl.trustStorePassword=yourCrazyPassword
"

What you're looking for is technically known as currying.

function getMyCallback(randomValue)
{
    return function(otherParam)
    {
        return randomValue * otherParam //or whatever it is you are doing.
    }

}

var myCallback = getMyCallBack(getRand())

alert(myCallBack(1));
alert(myCallBack(2));

The above isn't exactly a curried function but it achieves the result of maintaining an existing value without adding variables to the global namespace or requiring some other object repository for it.

This could also some extra reasons instead of the mentioned reasons :

• You have a crashed image : one of your images cannot be load
• adding an image to the drawable folder and modifying it's type (png ,jpg) while giving it a name(or inside the drawable folder using the rename function)

Getting variables into your CMake script

You can pass a variable on the line with the cmake invocation:

FOO=1 cmake

or by exporting a variable in BASH:

export FOO=1

Then you can pick it up in a cmake script using:

$ENV{FOO}

Think about this in terms of behaviour, not in terms of what methods there are. The method called method has a particular behaviour if b is true. It has different behaviour if b is false. This means you should write two different tests for method; one for each case. So instead of having three method-oriented tests (one for method, one for method1, one for method2, you have two behaviour-oriented tests.

Related to this (I suggested this in another SO thread recently, and got called a four-letter word as a result, so feel free to take this with a grain of salt); I find it helpful to choose test names that reflect the behaviour that I'm testing, rather than the name of the method. So don't call your tests testMethod(), testMethod1(), testMethod2() and so forth. I like names like calculatedPriceIsBasePricePlusTax() or taxIsExcludedWhenExcludeIsTrue() that indicate what behaviour I'm testing; then within each test method, test only the indicated behaviour. Most such behaviours will involve just one call to a public method, but may involve many calls to private methods.

Hope this helps.

upstream in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add. Depending on what you select for this name, your git pull usage will change. For example, if you use:

git remote add upstream git://github.com/somename/original-project.git

then you would use this to pull changes:

git pull upstream master

But, if you choose origin for the name of the remote repo, your commands would be:

To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git

And to pull: git pull origin master

We can use XOR operation which is safer than summation because in programming languages if the given input is large it may overflow and may give wrong answer.

Before going to the solution, know that A xor A = 0. So if we XOR two identical numbers the value is 0.

Now, XORing [1..n] with the elements present in the array cancels the identical numbers. So at the end we will get the missing number.

// Assuming that the array contains 99 distinct integers between 1..99
// and empty slot value is zero
int XOR = 0;
for(int i=0; i<100; i++) {
    if (ARRAY[i] != 0) // remove this condition keeping the body if no zero slot
        XOR ^= ARRAY[i];
    XOR ^= (i + 1);
}
return XOR;
//return XOR ^ ARRAY.length + 1; if your array doesn't have empty zero slot. 

Try this:

^[A-Za-z ].*

Another simpler solution is to use this formula in the conditional formatting (apply to column A):

=COUNTIF(B:B,A1)

Regards!

DNS answer above is actually incorrect. The SO is asking about milliseconds but the answer is for microseconds. Unfortunately, Python`s doesn't have a directive for milliseconds, just microseconds (see doc), but you can workaround it by appending three zeros at the end of the string and parsing the string as microseconds, something like:

datetime.strptime(time_str + '000', '%d/%m/%y %H:%M:%S.%f')

where time_str is formatted like 30/03/09 16:31:32.123.

Hope this helps.

Here is how you could do it with Java 11's java.net.http package:

    var fileA = new File("a.pdf");
    var fileB = new File("b.pdf");

    var mimeMultipartData = MimeMultipartData.newBuilder()
            .withCharset(StandardCharsets.UTF_8)
            .addFile("file1", fileA.toPath(), Files.probeContentType(fileA.toPath()))
            .addFile("file2", fileB.toPath(), Files.probeContentType(fileB.toPath()))
            .build();

    var request = HttpRequest.newBuilder()
            .header("Content-Type", mimeMultipartData.getContentType())
            .POST(mimeMultipartData.getBodyPublisher())
            .uri(URI.create("http://somehost/upload"))
            .build();

    var httpClient = HttpClient.newBuilder().build();
    var response = httpClient.send(request, BodyHandlers.ofString());

With the following MimeMultipartData:

public class MimeMultipartData {

    public static class Builder {

        private String boundary;
        private Charset charset = StandardCharsets.UTF_8;
        private List<MimedFile> files = new ArrayList<MimedFile>();
        private Map<String, String> texts = new LinkedHashMap<>();

        private Builder() {
            this.boundary = new BigInteger(128, new Random()).toString();
        }

        public Builder withCharset(Charset charset) {
            this.charset = charset;
            return this;
        }

        public Builder withBoundary(String boundary) {
            this.boundary = boundary;
            return this;
        }

        public Builder addFile(String name, Path path, String mimeType) {
            this.files.add(new MimedFile(name, path, mimeType));
            return this;
        }

        public Builder addText(String name, String text) {
            texts.put(name, text);
            return this;
        }

        public MimeMultipartData build() throws IOException {
            MimeMultipartData mimeMultipartData = new MimeMultipartData();
            mimeMultipartData.boundary = boundary;

            var newline = "\r\n".getBytes(charset);
            var byteArrayOutputStream = new ByteArrayOutputStream();
            for (var f : files) {
                byteArrayOutputStream.write(("--" + boundary).getBytes(charset)); 
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(("Content-Disposition: form-data; name=\"" + f.name + "\"; filename=\"" + f.path.getFileName() + "\"").getBytes(charset));
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(("Content-Type: " + f.mimeType).getBytes(charset));
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(Files.readAllBytes(f.path));
                byteArrayOutputStream.write(newline);
            }
            for (var entry: texts.entrySet()) {
                byteArrayOutputStream.write(("--" + boundary).getBytes(charset));
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(("Content-Disposition: form-data; name=\"" + entry.getKey() + "\"").getBytes(charset));
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(newline);
                byteArrayOutputStream.write(entry.getValue().getBytes(charset));
                byteArrayOutputStream.write(newline);
            }
            byteArrayOutputStream.write(("--" + boundary + "--").getBytes(charset));

            mimeMultipartData.bodyPublisher = BodyPublishers.ofByteArray(byteArrayOutputStream.toByteArray());
            return mimeMultipartData;
        }

        public class MimedFile {

            public final String name;
            public final Path path;
            public final String mimeType;

            public MimedFile(String name, Path path, String mimeType) {
                this.name = name;
                this.path = path;
                this.mimeType = mimeType;
            }
        }
    }

    private String boundary;
    private BodyPublisher bodyPublisher;

    private MimeMultipartData() {
    }

    public static Builder newBuilder() {
        return new Builder();
    }

    public BodyPublisher getBodyPublisher() throws IOException {
        return bodyPublisher;
    }

    public String getContentType() {
        return "multipart/form-data; boundary=" + boundary;
    }

}

They are both quite similar in solving for the solution, but as others have said, one (Logistic Regression) is for predicting a category "fit" (Y/N or 1/0), and the other (Linear Regression) is for predicting a value.

So if you want to predict if you have cancer Y/N (or a probability) - use logistic. If you want to know how many years you will live to - use Linear Regression !

You can create a custom view and put it inside a GestureDetector for it to behave like a button. The benefit is that you can provide endless types of custom decoration (including making it round with specified radius) to the container.

With pure JavaScript:

console.log(window.location.href)

Using Angular:

this.router.url

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
    template: 'The href is: {{href}}'
    /*
    Other component settings
    */
})
export class Component {
    public href: string = "";

    constructor(private router: Router) {}

    ngOnInit() {
        this.href = this.router.url;
        console.log(this.router.url);
    }
}

I have same scenario in my project and achieved using following method.

It works with all data types, few mentioned above doesn't work with date and empty arrays .

removeEmptyKeysFromObject.js

removeEmptyKeysFromObject(obj) {_x000D_
   Object.keys(obj).forEach(key => {_x000D_
  if (Object.prototype.toString.call(obj[key]) === '[object Date]' && (obj[key].toString().length === 0 || obj[key].toString() === 'Invalid Date')) {_x000D_
    delete obj[key];_x000D_
  } else if (obj[key] && typeof obj[key] === 'object') {_x000D_
    this.removeEmptyKeysFromObject(obj[key]);_x000D_
  } else if (obj[key] == null || obj[key] === '') {_x000D_
    delete obj[key];_x000D_
  }_x000D_
_x000D_
  if (obj[key]_x000D_
    && typeof obj[key] === 'object'_x000D_
    && Object.keys(obj[key]).length === 0_x000D_
    && Object.prototype.toString.call(obj[key]) !== '[object Date]') {_x000D_
    delete obj[key];_x000D_
  }_x000D_
});_x000D_
  return obj;_x000D_
}

pass any object to this function removeEmptyKeysFromObject()

<input type="text" required="true" value="" readonly>

Not the.

<input type="text" required="true" value="" readonly="true">

if you want to go to just want to go to previous activity use

finish();

OR

onBackPressed();

if you want to go to second activity or below that use following:

intent = new Intent(MyFourthActivity.this , MySecondActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
//Bundle is optional
Bundle bundle = new Bundle();
bundle.putString("MyValue1", val1);
intent.putExtras(bundle);
//end Bundle
startActivity(intent);

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

Simply do:

db.getCollection('test').find('4ecbe7f9e8c1c9092c000027');

With rails + arel, a more clear way:

# Table name: messages
#
# sender_id:    integer
# recipient_id: integer
# content:      text

class Message < ActiveRecord::Base
  scope :by_participant, ->(user_id) do
    left  = arel_table[:sender_id].eq(user_id)
    right = arel_table[:recipient_id].eq(user_id)

    where(Arel::Nodes::Or.new(left, right))
  end
end

Produces:

$ Message.by_participant(User.first.id).to_sql 
=> SELECT `messages`.* 
     FROM `messages` 
    WHERE `messages`.`sender_id` = 1 
       OR `messages`.`recipient_id` = 1

You can CHANGE user interface LANGUAGE like this:

Open VS > VS Community > Preferences > Environment > Visual Style > User Interface language

Woala!!!

public class Main {

    enum Vehical{
        Car,
        Bus,
        Van
    }

    public static void main(String[] args){

      String vehicalType = "CAR";

        if(vehicalType.equals(Vehical.Car.name())){
            System.out.println("The provider is Car");
        }

     String vehical_Type = "BUS";

       if(vehical_Type.equals(Vehical.Bus.toString())){
            System.out.println("The provider is Bus");
        }


    }
}

I use the version of NCover that comes with TestDriven.NET. It will allow you to easily right-click on your unit test class library, and hit Test With→Coverage, and it will pull up the report.

In MVC 5, things got easier:

return new StatusCodeResult(HttpStatusCode.NotModified, this);

You don't directly read a value. You can set it with .setValue(), but there is no .getValue() on the reference object.

You have to use a listener. If you just want to read the value once, you use ref.addListenerForSingleValueEvent().

Example:

Firebase ref = new Firebase("YOUR-URL-HERE/PATH/TO/YOUR/STUFF");
ref.addListenerForSingleValueEvent(new ValueEventListener() {
   @Override
   public void onDataChange(DataSnapshot dataSnapshot) {
       String value = (String) dataSnapshot.getValue();

       // do your stuff here with value

   }

   @Override
   public void onCancelled(FirebaseError firebaseError) {

   }
});

Here's what actually worked for me, after guidance from answers here:

export BASH_VARIABLE="[1,2,3]"
curl http://localhost:8080/path -d "$(cat <<EOF
{
  "name": $BASH_VARIABLE,
  "something": [
    "value1",
    "value2",
    "value3"
  ]
}
EOF
)" -H 'Content-Type: application/json'

No need to go with GSON for this; Jackson can do either plain Maps/Lists:

ObjectMapper mapper = new ObjectMapper();
Map<String,Object> map = mapper.readValue(json, Map.class);

or more convenient JSON Tree:

JsonNode rootNode = mapper.readTree(json);

By the way, there is no reason why you could not actually create Java classes and do it (IMO) more conveniently:

public class Library {
  @JsonProperty("libraryname")
  public String name;

  @JsonProperty("mymusic")
  public List<Song> songs;
}
public class Song {
  @JsonProperty("Artist Name") public String artistName;
  @JsonProperty("Song Name") public String songName;
}

Library lib = mapper.readValue(jsonString, Library.class);

NOTE: Not 100% Cross Browser

Check browser compatibility @ http://caniuse.com/#search=FileReader

as you will see people have had issues with the not so common browsers, But this could come down to the version of the browser.. I always recommend using something like caniuse to see what generation of browser is supported... This is only a working answer for the user, not a final copy and paste code for people to just use..

The Fiddle: http://jsfiddle.net/d2atnbrt/3/

THE HTML CODE:

<input type="file" id="my_file_input" />
<div id='my_file_output'></div>

THE JS CODE:

var oFileIn;

$(function() {
    oFileIn = document.getElementById('my_file_input');
    if(oFileIn.addEventListener) {
        oFileIn.addEventListener('change', filePicked, false);
    }
});


function filePicked(oEvent) {

    var oFile = oEvent.target.files[0];
    var sFilename = oFile.name;
    // Create A File Reader HTML5
    var reader = new FileReader();

    // Ready The Event For When A File Gets Selected
    reader.onload = function(e) {
        var data = e.target.result;
        var cfb = XLS.CFB.read(data, {type: 'binary'});
        var wb = XLS.parse_xlscfb(cfb);
        // Loop Over Each Sheet
        wb.SheetNames.forEach(function(sheetName) {

        });
    };

    // Tell JS To Start Reading The File.. You could delay this if desired
    reader.readAsBinaryString(oFile);
}

This also requires https://cdnjs.cloudflare.com/ajax/libs/xls/0.7.4-a/xls.js to convert to a readable format, i've also used jquery only for changing the div contents and for the dom ready event.. so jquery is not needed

This is as basic as i could get it,

EDIT - Generating A Table

The Fiddle: http://jsfiddle.net/d2atnbrt/5/

This second fiddle shows an example of generating your own table, the key here is using sheet_to_json to get the data in the correct format for JS use..

One or two comments in the second fiddle might be incorrect as modified version of the first fiddle.. the CSV comment is at least

Test XLS File: http://www.whitehouse.gov/sites/default/files/omb/budget/fy2014/assets/receipts.xls

This does not cover XLSX files thought, it should be fairly easy to adjust for them using their examples.

According to my research there is no way to do this exactly the way you want. You can manually re-create the table and copy the data, or SSMS can (and will) do this for you (when you drag and drop a column to a different order, it does this). In fact it souldn't matter what order the columns are... As an alternative solution you can select the data you want in the order you desired. For example, instead of using asterisk (*) in select, specify the column names in some order... Lets say MyTable has col1, col2, col3, colNew columns.

Instead of:

SELECT * FROM MyTable

You can use:

SELECT col1, colNew, col2, col3 FROM MyTable

Actually, I think the BigInteger is solution is very nice:

new BigInteger("00A0BF", 16).toByteArray();

Edit: Not safe for leading zeros, as noted by the poster.

If you don't want to use html/dom, you could use regex. I haven't tested this; but something along the lines of:

function parseHtmlEntities(str) {
    return str.replace(/&#([0-9]{1,3});/gi, function(match, numStr) {
        var num = parseInt(numStr, 10); // read num as normal number
        return String.fromCharCode(num);
    });
}

[Edit]

Note: this would only work for numeric html-entities, and not stuff like &oring;.

[Edit 2]

Fixed the function (some typos), test here: http://jsfiddle.net/Be2Bd/1/

This is all you need:

background-repeat: no-repeat;

check this code:

CREATE TRIGGER trig_Update_Employee ON [EmployeeResult] FOR INSERT AS Begin   
    Insert into Employee (Name, Department)  
    Select Distinct i.Name, i.Department   
        from Inserted i
        Left Join Employee e on i.Name = e.Name and i.Department = e.Department
        where e.Name is null
End

Use a+ to open a file for reading, writing as well as create it if it doesn't exist.

a+ Opens a file for both appending and reading. The file pointer is at the end of the file if the file exists. The file opens in the append mode. If the file does not exist, it creates a new file for reading and writing. -Python file modes

with open('"File.txt', 'a+') as file:
    print(file.readlines())
    file.write("test")

Note: opening file in a with block makes sure that the file is properly closed at the block's end, even if an exception is raised on the way. It's equivalent to try-finally, but much shorter.

I could not get any of these answers to work. Here's what I ended up putting at the very top of my Vagrantfile, before the Vagrant::Config.run do block:

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "1024"]
  end
end

I noticed that the shortcut accessor style, "vb.memory = 1024", didn't seem to work.

Using Set

this.items = new Set();
this.items.add(1);
this.items.add(2);
this.items.add(1);
this.items.add(2);

console.log(Array.from(this.items)); // [1, 2]

Here's one way to do it:

if not any(d['main_color'] == 'red' for d in a):
    # does not exist

The part in parentheses is a generator expression that returns True for each dictionary that has the key-value pair you are looking for, otherwise False.

If the key could also be missing the above code can give you a KeyError. You can fix this by using get and providing a default value. If you don't provide a default value, None is returned.

if not any(d.get('main_color', default_value) == 'red' for d in a):
    # does not exist

The concept of interval notation comes up in both Mathematics and Computer Science. The Mathematical notation [, ], (, ) denotes the domain (or range) of an interval.

• The brackets [ and ] means:

  1. The number is included,
  2. This side of the interval is closed,

• The parenthesis ( and ) means:

  1. The number is excluded,
  2. This side of the interval is open.

An interval with mixed states is called "half-open".

For example, the range of consecutive integers from 1 .. 10 (inclusive) would be notated as such:

• [1,10]

Notice how the word inclusive was used. If we want to exclude the end point but "cover" the same range we need to move the end-point:

• [1,11)

For both left and right edges of the interval there are actually 4 permutations:

(1,10) =   2,3,4,5,6,7,8,9       Set has  8 elements
(1,10] =   2,3,4,5,6,7,8,9,10    Set has  9 elements
[1,10) = 1,2,3,4,5,6,7,8,9       Set has  9 elements
[1,10] = 1,2,3,4,5,6,7,8,9,10    Set has 10 elements

How does this relate to Mathematics and Computer Science?

Array indexes tend to use a different offset depending on which field are you in:

• Mathematics tends to be one-based.
• Certain programming languages tends to be zero-based, such as C, C++, Javascript, Python, while other languages such as Mathematica, Fortran, Pascal are one-based.

These differences can lead to subtle fence post errors, aka, off-by-one bugs when implementing Mathematical algorithms such as for-loops.

Integers

If we have a set or array, say of the first few primes [ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 ], Mathematicians would refer to the first element as the 1st absolute element. i.e. Using subscript notation to denote the index:

• a₁ = 2
• a₂ = 3
• :
• a₁₀ = 29

Some programming languages, in contradistinction, would refer to the first element as the zero'th relative element.

• a[0] = 2
• a[1] = 3
• :
• a[9] = 29

Since the array indexes are in the range [0,N-1] then for clarity purposes it would be "nice" to keep the same numerical value for the range 0 .. N instead of adding textual noise such as a -1 bias.

For example, in C or JavaScript, to iterate over an array of N elements a programmer would write the common idiom of i = 0, i < N with the interval [0,N) instead of the slightly more verbose [0,N-1]:

function main() {_x000D_
    var output = "";_x000D_
    var a = [ 2, 3, 5, 7,  11, 13, 17, 19, 23, 29 ];_x000D_
    for( var i = 0; i < 10; i++ ) // [0,10)_x000D_
       output += "[" + i + "]: " + a[i] + "\n";_x000D_
_x000D_
    if (typeof window === 'undefined') // Node command line_x000D_
        console.log( output )_x000D_
    else_x000D_
        document.getElementById('output1').innerHTML = output;_x000D_
}

 <html>_x000D_
     <body onload="main();">_x000D_
         <pre id="output1"></pre>_x000D_
     </body>_x000D_
 </html>

Mathematicians, since they start counting at 1, would instead use the i = 1, i <= N nomenclature but now we need to correct the array offset in a zero-based language.

e.g.

function main() {_x000D_
    var output = "";_x000D_
    var a = [ 2, 3, 5, 7,  11, 13, 17, 19, 23, 29 ];_x000D_
    for( var i = 1; i <= 10; i++ ) // [1,10]_x000D_
       output += "[" + i + "]: " + a[i-1] + "\n";_x000D_
_x000D_
    if (typeof window === 'undefined') // Node command line_x000D_
        console.log( output )_x000D_
    else_x000D_
        document.getElementById( "output2" ).innerHTML = output;_x000D_
}

<html>_x000D_
    <body onload="main()";>_x000D_
        <pre id="output2"></pre>_x000D_
    </body>_x000D_
</html>

Aside:

In programming languages that are 0-based you might need a kludge of a dummy zero'th element to use a Mathematical 1-based algorithm. e.g. Python Index Start

Floating-Point

Interval notation is also important for floating-point numbers to avoid subtle bugs.

When dealing with floating-point numbers especially in Computer Graphics (color conversion, computational geometry, animation easing/blending, etc.) often times normalized numbers are used. That is, numbers between 0.0 and 1.0.

It is important to know the edge cases if the endpoints are inclusive or exclusive:

• (0,1) = 1e-M .. 0.999...
• (0,1] = 1e-M .. 1.0
• [0,1) = 0.0 .. 0.999...
• [0,1] = 0.0 .. 1.0

Where M is some machine epsilon. This is why you might sometimes see const float EPSILON = 1e-# idiom in C code (such as 1e-6) for a 32-bit floating point number. This SO question Does EPSILON guarantee anything? has some preliminary details. For a more comprehensive answer see FLT_EPSILON and David Goldberg's What Every Computer Scientist Should Know About Floating-Point Arithmetic

Some implementations of a random number generator, random() may produce values in the range 0.0 .. 0.999... instead of the more convenient 0.0 .. 1.0. Proper comments in the code will document this as [0.0,1.0) or [0.0,1.0] so there is no ambiguity as to the usage.

Example:

• You want to generate random() colors. You convert three floating-point values to unsigned 8-bit values to generate a 24-bit pixel with red, green, and blue channels respectively. Depending on the interval output by random() you may end up with near-white (254,254,254) or white (255,255,255).

     +--------+-----+
     |random()|Byte |
     |--------|-----|
     |0.999...| 254 | <-- error introduced
     |1.0     | 255 |
     +--------+-----+

For more details about floating-point precision and robustness with intervals see Christer Ericson's Real-Time Collision Detection, Chapter 11 Numerical Robustness, Section 11.3 Robust Floating-Point Usage.

Blimey. This was a really useful thread to discover.

I still found some of these suggestions confusing. Whenever I used value with [1] in the string, it would only retrieved the first value. And some suggestions recommended using cross apply which (in my tests) just brought back far too much data.

So, here's my simple example of how you'd create an xml object, then read out its values into a table.

DECLARE @str nvarchar(2000)

SET @str = ''
SET @str = @str + '<users>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Mike</firstName>'
SET @str = @str + '     <lastName>Gledhill</lastName>'
SET @str = @str + '     <age>31</age>'
SET @str = @str + '  </user>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Mark</firstName>'
SET @str = @str + '     <lastName>Stevens</lastName>'
SET @str = @str + '     <age>42</age>'
SET @str = @str + '  </user>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Sarah</firstName>'
SET @str = @str + '     <lastName>Brown</lastName>'
SET @str = @str + '     <age>23</age>'
SET @str = @str + '  </user>'
SET @str = @str + '</users>'

DECLARE @xml xml
SELECT @xml = CAST(CAST(@str AS VARBINARY(MAX)) AS XML) 

--  Iterate through each of the "users\user" records in our XML
SELECT 
    x.Rec.query('./firstName').value('.', 'nvarchar(2000)') AS 'FirstName',
    x.Rec.query('./lastName').value('.', 'nvarchar(2000)') AS 'LastName',
    x.Rec.query('./age').value('.', 'int') AS 'Age'
FROM @xml.nodes('/users/user') as x(Rec)

And here's the output:

It's bizarre syntax, but with a decent example, it's easy enough to add to your own SQL Server functions.

Speaking of which, here's the correct answer to this question.

Assuming your have your xml data in an @xml variable of type xml (as demonstrated in my example above), here's how you would return the three rows of data from the xml quoted in the question:

SELECT 
    x.Rec.query('./firstName').value('.', 'nvarchar(2000)') AS 'FirstName',
    x.Rec.query('./lastName').value('.', 'nvarchar(2000)') AS 'LastName'
FROM @xml.nodes('/person') as x(Rec)

All of the above solutions doesn't work for me, Sending bitmap as parceableByteArray also generates error android.os.TransactionTooLargeException: data parcel size.

Solution

1. Saved the bitmap in internal storage as:

public String saveBitmap(Bitmap bitmap) {
        String fileName = "ImageName";//no .png or .jpg needed
        try {
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
            FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
            fo.write(bytes.toByteArray());
            // remember close file output
            fo.close();
        } catch (Exception e) {
            e.printStackTrace();
            fileName = null;
        }
        return fileName;
    }

2. and send in putExtra(String) as

Intent intent = new Intent(ActivitySketcher.this,ActivityEditor.class);
intent.putExtra("KEY", saveBitmap(bmp));
startActivity(intent);

3. and Receive it in other activity as:

if(getIntent() != null){
  try {
           src = BitmapFactory.decodeStream(openFileInput("myImage"));
       } catch (FileNotFoundException e) {
            e.printStackTrace();
      }

 }

Using SQL Management Studio Express:

In the Object Explorer tree drill down under Management to "Activity Monitor" (if you cannot find it there then right click on the database server and select "Activity Monitor"). Opening the Activity Monitor, you can view all process info. You should be able to find the locks for the database you're interested in and kill those locks, which will also kill the connection.

You should be able to rename after that.

The algorithm you are using, "AES", is a shorthand for "AES/ECB/NoPadding". What this means is that you are using the AES algorithm with 128-bit key size and block size, with the ECB mode of operation and no padding.

In other words: you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception.

If you want to encrypt data in sizes that are not multiple of 16 bytes, you are either going to have to use some kind of padding, or a cipher-stream. For instance, you could use CBC mode (a mode of operation that effectively transforms a block cipher into a stream cipher) by specifying "AES/CBC/NoPadding" as the algorithm, or PKCS5 padding by specifying "AES/ECB/PKCS5", which will automatically add some bytes at the end of your data in a very specific format to make the size of the ciphertext multiple of 16 bytes, and in a way that the decryption algorithm will understand that it has to ignore some data.

In any case, I strongly suggest that you stop right now what you are doing and go study some very introductory material on cryptography. For instance, check Crypto I on Coursera. You should understand very well the implications of choosing one mode or another, what are their strengths and, most importantly, their weaknesses. Without this knowledge, it is very easy to build systems which are very easy to break.

Update: based on your comments on the question, don't ever encrypt passwords when storing them at a database!!!!! You should never, ever do this. You must HASH the passwords, properly salted, which is completely different from encrypting. Really, please, don't do what you are trying to do... By encrypting the passwords, they can be decrypted. What this means is that you, as the database manager and who knows the secret key, you will be able to read every password stored in your database. Either you knew this and are doing something very, very bad, or you didn't know this, and should get shocked and stop it.

Both certificates should exist prior to the connection. They're usually created by Certification Authorities (not necessarily the same). (There are alternative cases where verification can be done differently, but some verification will need to be made.)

The server certificate should be created by a CA that the client trusts (and following the naming conventions defined in RFC 6125).

The client certificate should be created by a CA that the server trusts.

It's up to each party to choose what it trusts.

There are online CA tools that will allow you to apply for a certificate within your browser and get it installed there once the CA has issued it. They need not be on the server that requests client-certificate authentication.

The certificate distribution and trust management is the role of the Public Key Infrastructure (PKI), implemented via the CAs. The SSL/TLS client and servers and then merely users of that PKI.

When the client connects to a server that requests client-certificate authentication, the server sends a list of CAs it's willing to accept as part of the client-certificate request. The client is then able to send its client certificate, if it wishes to and a suitable one is available.

The main advantages of client-certificate authentication are:

• The private information (the private key) is never sent to the server. The client doesn't let its secret out at all during the authentication.
• A server that doesn't know a user with that certificate can still authenticate that user, provided it trusts the CA that issued the certificate (and that the certificate is valid). This is very similar to the way passports are used: you may have never met a person showing you a passport, but because you trust the issuing authority, you're able to link the identity to the person.

You may be interested in Advantages of client certificates for client authentication? (on Security.SE).

I had the same problem as you, Noboby can understand me, But I solved it in this way.

SELECT NAME, TELEFONE, DATA
FROM   [sheet1$a1:q633]
WHERE  NAME IN (SELECT * FROM  [sheet2$a1:a2])

you need insert a parameter in other sheet, the SQL will consider that information like as database, then you can select the information and compare them into parameter you like.

Also you can use $('input[name="selector[]"]').serialize();. It returns URL encoded string like: "selector%5B%5D=1&selector%5B%5D=3"

I use " as a top-tier and ' as a second tier, as I imagine most people do. For example

<a href="#" onclick="alert('Clicked!');">Click Me!</a>

In that example, you must use both, it is unavoidable.

It's called a for-each or enhanced for statement. See the JLS §14.14.2.

It's syntactic sugar provided by the compiler for iterating over Iterables and arrays. The following are equivalent ways to iterate over a list:

List<Foo> foos = ...;
for (Foo foo : foos)
{
    foo.bar();
}

// equivalent to:
List<Foo> foos = ...;
for (Iterator<Foo> iter = foos.iterator(); iter.hasNext();)
{
    Foo foo = iter.next();
    foo.bar();
}

and these are two equivalent ways to iterate over an array:

int[] nums = ...;
for (int num : nums)
{
    System.out.println(num);
}

// equivalent to:
int[] nums = ...;
for (int i=0; i<nums.length; i++)
{
    int num = nums[i];
    System.out.println(num);
}

I would consider Dependencies, Android Libraries and Multi-project setup necessary reading. Please take a few minutes to do so.

Particularly, in the case of a non-jar library project, read the following snippet from above source:

Gradle projects can also depend on other gradle projects by using a multi-project setup. A multi-project setup usually works by having all the projects as sub folders of a given root project.

For instance, given to following structure:

MyProject/
 + app/
 + libraries/
    + lib1/
    + lib2/

We can identify 3 projects. Gradle will reference them with the following name:

:app
:libraries:lib1
:libraries:lib2

Each projects will have its own build.gradle declaring how it gets built. Additionally, there will be a file called settings.gradle at the root declaring the projects. This gives the following structure:

MyProject/
 | settings.gradle
 + app/
    | build.gradle
 + libraries/
    + lib1/
       | build.gradle
    + lib2/
       | build.gradle

The content of settings.gradle is very simple:

include ':app', ':libraries:lib1', ':libraries:lib2'

This defines which folder is actually a Gradle project.

The :app project is likely to depend on the libraries, and this is done by declaring the following dependencies:

dependencies {
    compile project(':libraries:lib1')
}

Kindly note that there was little or no use of Android Studio GUI to make this happen.

I am currently using git submodules to link the nested library to the actual library git repo to avoid a dependency mess.

document.forms[0].elements[0].focus();

This can be refined using a loop to eg. not focus certain types of field, disabled fields and so on. Better may be to add a class="autofocus" to the field you actually do want focused, and loop over forms[i].elements[j] looking for that className.

Anyhow: it's not normally a good idea to do this on every page. When you focus an input the user loses the ability to eg. scroll the page from the keyboard. If unexpected, this can be annoying, so only auto-focus when you're pretty sure that using the form field is going to be what the user wants to do. ie. if you're Google.

if you are using jquery-validate.js in your application then use below expression.

if($("#spa").is(":blank"))
{
  //code
}

Once when I was interviewing for Microsoft in college, the guy asked me how to detect a cycle in a linked list.

Having discussed in class the prior week the optimal solution to the problem, I started to tell him.

He told me, "No, no, everybody gives me that solution. Give me a different one."

I argued that my solution was optimal. He said, "I know it's optimal. Give me a sub-optimal one."

At the same time, it's a pretty good problem.

Namespace level: internal

Type level: private

Is your repository at "upstream" a bare repository? I got the same error, but when I change to bare they no longer happen.

Syntactic sugar, makes it more obvious to the casual reader that the join isn't an inner one.

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

Repeatable Read

The state of the database is maintained from the start of the transaction. If you retrieve a value in session1, then update that value in session2, retrieving it again in session1 will return the same results. Reads are repeatable.

session1> BEGIN;
session1> SELECT firstname FROM names WHERE id = 7;
Aaron

session2> BEGIN;
session2> SELECT firstname FROM names WHERE id = 7;
Aaron
session2> UPDATE names SET firstname = 'Bob' WHERE id = 7;
session2> SELECT firstname FROM names WHERE id = 7;
Bob
session2> COMMIT;

session1> SELECT firstname FROM names WHERE id = 7;
Aaron

Read Committed

Within the context of a transaction, you will always retrieve the most recently committed value. If you retrieve a value in session1, update it in session2, then retrieve it in session1again, you will get the value as modified in session2. It reads the last committed row.

session1> BEGIN;
session1> SELECT firstname FROM names WHERE id = 7;
Aaron

session2> BEGIN;
session2> SELECT firstname FROM names WHERE id = 7;
Aaron
session2> UPDATE names SET firstname = 'Bob' WHERE id = 7;
session2> SELECT firstname FROM names WHERE id = 7;
Bob
session2> COMMIT;

session1> SELECT firstname FROM names WHERE id = 7;
Bob

Makes sense?

When your function is deterministic, you are safe to declare it to be deterministic. The location of "DETERMINISTIC" keyword is as follows.

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        Intent i = new Intent(getActivity(), DiscussAddValu.class);
        startActivity(i);
    }
});

list=[1.1412, 4.3453, 5.8709, 0.1314]
list.index(min(list))

Will give you first index of minimum.

There is a strcat() function from the ported C library that will do "C style string" concatenation for you.

BTW even though C++ has a bunch of functions to deal with C-style strings, it could be beneficial for you do try and come up with your own function that does that, something like:

char * con(const char * first, const char * second) {
    int l1 = 0, l2 = 0;
    const char * f = first, * l = second;

    // step 1 - find lengths (you can also use strlen)
    while (*f++) ++l1;
    while (*l++) ++l2;

    char *result = new char[l1 + l2];

    // then concatenate
    for (int i = 0; i < l1; i++) result[i] = first[i];
    for (int i = l1; i < l1 + l2; i++) result[i] = second[i - l1];

    // finally, "cap" result with terminating null char
    result[l1+l2] = '\0';
    return result;
}

...and then...

char s1[] = "file_name";
char *c = con(s1, ".txt");

... the result of which is file_name.txt.

You might also be tempted to write your own operator + however IIRC operator overloads with only pointers as arguments is not allowed.

Also, don't forget the result in this case is dynamically allocated, so you might want to call delete on it to avoid memory leaks, or you could modify the function to use stack allocated character array, provided of course it has sufficient length.

Araxis Merge http://www.araxis.com/merge I'm using it on Mac OS X but I've used it on windows... it's not free... but it has some nice features... nicer on windows though.

If you want to use a class:

from datetime import datetime,timedelta

class MyThread(): 

    def __init__(self, name, timeLimit):        
        self.name = name
        self.timeLimit = timeLimit
    def run(self): 
        # get the start time
        startTime = datetime.now()
    
        while True:
           # stop if the time limit is reached :
           if((datetime.now()-startTime)>self.timeLimit):
               break
           print('A')

mt = MyThread('aThread',timedelta(microseconds=20000))
mt.run()

If you happen to use Spring Boot you can make use of the BuildProperties class.

Take the following snippet from our OpenAPI configuration class as an example:

@Configuration
@RequiredArgsConstructor // <- lombok
public class OpenApi {

    private final BuildProperties buildProperties; // <- you can also autowire it

    @Bean
    public OpenAPI yourBeautifulAPI() {
        return new OpenAPI().info(new Info()
            .title(buildProperties.getName())
            .description("The description")
            .version(buildProperties.getVersion())
            .license(new License().name("Your company")));
    }
}

<script>
function subadd(){
subadd= parseFloat(document.forms[0][0].value) + parseFloat(document.forms[0][1].value) 
window.alert(subadd)  
}
</script>

<body>
<form>
<input type="text" >+
<input type="text" >
<input type="button" value="add" onclick="subadd()">
</form>
</body>

What you want is maxlength.

Valid for text, search, url, tel, email, and password, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.

You might consider using one of these input types.

    $.validator.methods.checkEmail = function( value, element ) {
        return this.optional( element ) || /[a-z]+@[a-z]+\.[a-z]+/.test( value );
    }

    $("#myForm").validate({
        rules: {
            email: {
                required: true,
                checkEmail: true
            }
        },
        messages: {
            email: "incorrect email"
        }
    });

Even though this thread is old but gold. QCustomPlot is very recommendable as well to complement this list.

My solution to not having sessionStorage transferable over tabs was to create a localProfile and bang off this variable. If this variable is set but my sessionStorage variables arent go ahead and reinitialize them. When user logs out window closes destroy this localStorage variable

About generating the same random number if you call it in a loop a nifty solution is to declare the new Random() object outside of the loop as a global variable.

Notice that you have to declare your instance of the Random class outside of the GetRandomInt function if you are going to be running this in a loop.

“Why is this?” you ask.

Well, the Random class actually generates pseudo random numbers, with the “seed” for the randomizer being the system time. If your loop is sufficiently fast, the system clock time will not appear different to the randomizer and each new instance of the Random class would start off with the same seed and give you the same pseudo random number.

The order of elements in an array ([]) is maintained. The order of elements (name:value pairs) in an "object" ({}) is not, and it's usual for them to be "jumbled", if not by the JSON formatter/parser itself then by the language-specific objects (Dictionary, NSDictionary, Hashtable, etc) that are used as an internal representation.

put your session() auth in all server side pages accepting an ajax request:

if(require_once("auth.php")) {

//run json code

}

// do nothing otherwise

that's about the only way I've ever done it.

Visual Studio Express for Windows needs Windows 8.1. Having a look at the requirements page you might want to try the Web or Windows Desktop version which are able to run under Windows 7.

Tried to add this as a comment to Rob Prouse's posting, but the lack of formatting made it unintelligible.

In Visual Studio 2010, the "Tools | Options | Projects and Solutions | VC++ Directories" dialog reports that "VC++ Directories editing in Tools > Options has been deprecated", proposing that you use the rather counter-intuitive Property Manager.

If you really, really want to update the default $(IncludePath), you have to hack the appropriate entry in one of the XML files:

\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\PlatformToolsets\v100\Microsoft.Cpp.Win32.v100.props

or

\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\x64\PlatformToolsets\v100\Microsoft.Cpp.X64.v100.props

(Probably not Microsoft-recommended.)

Not enough rep for a comment.

The getElementById() based method in the selected answer won't work if the anchor has name but not id set (which is not recommended, but does happen in the wild).

Something to bare in mind if you don't have control of the document markup (e.g. webextension).

The location based method in the selected answer can also be simplified with location.replace:

function jump(hash) { location.replace("#" + hash) }

You should convert them to number before compare.

Try:

if (+x > +y) {
  //...
}

or

if (Number(x) > Number(y)) {
  // ...
}

Note: parseFloat and pareseInt(for compare integer, and you need to specify the radix) will give you NaN for an empty string, compare with NaN will always be false, If you don't want to treat empty string be 0, then you could use them.

Use +=

$val = 0;

foreach($arr as $var) {
   $val += $var; 
}

echo $val;

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

It sounds like Apache is warning you that you have multiple <VirtualHost> sections with the same IP address and port... as far as getting it to work without warnings, I think you would need to use something like Server Name Indication (SNI), a way of identifying the hostname requested as part of the SSL handshake. Basically it lets you do name-based virtual hosting over SSL, but I'm not sure how well it's supported by browsers. Other than something like SNI, you're basically limited to one SSL-enabled domain name for each IP address you expose to the public internet.

Of course, if you are able to access the websites properly, you'll probably be fine ignoring the warnings. These particular ones aren't very serious - they're mainly an indication of what to look at if you are experiencing problems

The problem is due to older version of ojdbc - ojdbc14.

Place the latest version of ojdbc jar file in your application or shared library. (Only one version should be there and it should be the latest one) As of today - ojdbc6.jar

Check the application libraries and shared libraries on server.

Add it to the session, not to the request.

HttpSession session = request.getSession();
session.setAttribute("object", object);

Also, don't use scriptlets in the JSP. Use EL instead; to access object all you need is ${object}.

A primary feature of JSP technology version 2.0 is its support for an expression language (EL). An expression language makes it possible to easily access application data stored in JavaBeans components. For example, the JSP expression language allows a page author to access a bean using simple syntax such as ${name} for a simple variable or ${name.foo.bar} for a nested property.

You can use this

    TextView output = (TextView) findViewById(R.id.output);
    one.setOnClickListener(youractivity.this);
    // set the onclicklistener for other buttons also

    @Override
    public void onClick(View v) {
      int id = v.getId();
    switch(id) {
    case R.id.oneButton:      
       append("1",output);
       break;
    case R.id.twoButton:
        append("2",output);
       break;
    case R.id.threeButton:
        append("3",output);
       break;
     } 
      }

 private void append(String s,TextView t){
  t.setText(s); 
}

you can identify the views in your activity in a separate method.

Based on Tim Down's answer, but it checks for the last known "good" text row. It places the cursor at the very end.

Furthermore, I could also recursively/iteratively check the last child of each consecutive last child to find the absolute last "good" text node in the DOM.

  setCaret(document.getElementById("editable"));_x000D_

It would be easier to use XML in SQL Server to insert multiple rows otherwise it becomes very tedious.

View full article with code explanations here http://www.cyberminds.co.uk/blog/articles/how-to-insert-multiple-rows-in-sql-server.aspx

Copy the following code into sql server to view a sample.

declare @test nvarchar(max)

set @test = '<topic><dialog id="1" answerId="41">
        <comment>comment 1</comment>
        </dialog>
    <dialog id="2" answerId="42" >
    <comment>comment 2</comment>
        </dialog>
    <dialog id="3" answerId="43" >
    <comment>comment 3</comment>
        </dialog>
    </topic>'

declare @testxml xml
set @testxml = cast(@test as xml)
declare @answerTemp Table(dialogid int, answerid int, comment varchar(1000))

insert @answerTemp
SELECT  ParamValues.ID.value('@id','int') ,
ParamValues.ID.value('@answerId','int') ,
ParamValues.ID.value('(comment)[1]','VARCHAR(1000)')
FROM @testxml.nodes('topic/dialog') as ParamValues(ID)

You should really prefer a solution that uses java.util.concurrent. Find and read Josh Bloch and/or Brian Goetz on the topic.

If you are not using java.util.concurrent.* and are taking responsibility for using Threads directly, then you should probably use join() to know when a thread is done. Here is a super simple Callback mechanism. First extend the Runnable interface to have a callback:

public interface CallbackRunnable extends Runnable {
    public void callback();
}

Then make an Executor that will execute your runnable and call you back when it is done.

public class CallbackExecutor implements Executor {

    @Override
    public void execute(final Runnable r) {
        final Thread runner = new Thread(r);
        runner.start();
        if ( r instanceof CallbackRunnable ) {
            // create a thread to perform the callback
            Thread callerbacker = new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        // block until the running thread is done
                        runner.join();
                        ((CallbackRunnable)r).callback();
                    }
                    catch ( InterruptedException e ) {
                        // someone doesn't want us running. ok, maybe we give up.
                    }
                }
            });
            callerbacker.start();
        }
    }

}

The other sort-of obvious thing to add to your CallbackRunnable interface is a means to handle any exceptions, so maybe put a public void uncaughtException(Throwable e); line in there and in your executor, install a Thread.UncaughtExceptionHandler to send you to that interface method.

But doing all that really starts to smell like java.util.concurrent.Callable. You should really look at using java.util.concurrent if your project permits it.

For very large output logs it could be difficult to open (network delay, scrolling). This is the solution I'm using to check big log files:

    https://${URL}/jenkins/job/${jobName}/${buildNumber}/

in the left column you see: View as plain text. Do a right mouse click on it and choose save links as. Now you can save your big log as .txt file. Open it with notepad++ and you can go through your logs easily without network delays during scrolling.

This message from Linus himself can help you with some other limits

[...] CVS, ie it really ends up being pretty much oriented to a "one file at a time" model.

Which is nice in that you can have a million files, and then only check out a few of them - you'll never even see the impact of the other 999,995 files.

Git fundamentally never really looks at less than the whole repo. Even if you limit things a bit (ie check out just a portion, or have the history go back just a bit), git ends up still always caring about the whole thing, and carrying the knowledge around.

So git scales really badly if you force it to look at everything as one huge repository. I don't think that part is really fixable, although we can probably improve on it.

And yes, then there's the "big file" issues. I really don't know what to do about huge files. We suck at them, I know.

See more in my other answer: the limit with Git is that each repository must represent a "coherent set of files", the "all system" in itself (you can not tag "part of a repository").
If your system is made of autonomous (but inter-dependent) parts, you must use submodules.

As illustrated by Talljoe's answer, the limit can be a system one (large number of files), but if you do understand the nature of Git (about data coherency represented by its SHA-1 keys), you will realize the true "limit" is a usage one: i.e, you should not try to store everything in a Git repository, unless you are prepared to always get or tag everything back. For some large projects, it would make no sense.

For a more in-depth look at git limits, see "git with large files"
(which mentions git-lfs: a solution to store large files outside the git repo. GitHub, April 2015)

The three issues that limits a git repo:

• huge files (the xdelta for packfile is in memory only, which isn't good with large files)
• huge number of files, which means, one file per blob, and slow git gc to generate one packfile at a time.
• huge packfiles, with a packfile index inefficient to retrieve data from the (huge) packfile.

A more recent thread (Feb. 2015) illustrates the limiting factors for a Git repo:

Will a few simultaneous clones from the central server also slow down other concurrent operations for other users?

There are no locks in server when cloning, so in theory cloning does not affect other operations. Cloning can use lots of memory though (and a lot of cpu unless you turn on reachability bitmap feature, which you should).

Will 'git pull' be slow?

If we exclude the server side, the size of your tree is the main factor, but your 25k files should be fine (linux has 48k files).

'git push'?

This one is not affected by how deep your repo's history is, or how wide your tree is, so should be quick..

Ah the number of refs may affect both git-push and git-pull.
I think Stefan knows better than I in this area.

'git commit'? (It is listed as slow in reference 3.) 'git status'? (Slow again in reference 3 though I don't see it.)
(also git-add)

Again, the size of your tree. At your repo's size, I don't think you need to worry about it.

Some operations might not seem to be day-to-day but if they are called frequently by the web front-end to GitLab/Stash/GitHub etc then they can become bottlenecks. (e.g. 'git branch --contains' seems terribly adversely affected by large numbers of branches.)

git-blame could be slow when a file is modified a lot.

You can use Dagger to create a reference of that receiver.

First provide it:

@Provides
@YourScope
fun providesReceiver(): NotificationReceiver{
    return NotificationReceiver()
}

Then inject it where you need (using constructor or field injection)

and simply pass it to registerReceiver.

Also put it in try/catch block too.

Run the command java -X and you will get a list of all -X options:

C:\Users\Admin>java -X
-Xmixed           mixed mode execution (default)
-Xint             interpreted mode execution only
-Xbootclasspath:<directories and zip/jar files separated by ;>
                      set search path for bootstrap classes and resources
-Xbootclasspath/a:<directories and zip/jar files separated by ;>
                      append to end of bootstrap class path
-Xbootclasspath/p:<directories and zip/jar files separated by ;>
                      prepend in front of bootstrap class path
-Xdiag            show additional diagnostic messages
-Xnoclassgc       disable class garbage collection

-Xrs              reduce use of OS signals by Java/VM (see documentation)
-Xcheck:jni       perform additional checks for JNI functions
-Xshare:off       do not attempt to use shared class data
-Xshare:auto      use shared class data if possible (default)
-Xshare:on        require using shared class data, otherwise fail.
-XshowSettings    show all settings and continue

-XshowSettings:vm          show all vm related settings and continue
-XshowSettings:properties  show all property settings and continue
-XshowSettings:locale      show all locale related settings and continue

The -X options are non-standard and subject to change without notice.

I hope this will help you understand Xms, Xmx as well as many other things that matters the most. :)

Restarting logcat helps me always.

I tried everything here (and some otherplaces), and what worked for me (after doing all of these, the registry changes are mandatory I think) was to change the setting for Icon Overlays\Status Cache from Default to Shell, and I also checked "Show overlays and context menu only in explorer". Not sure which of those two did it but it works now.

Spring MVC and Spring Boot are exist for the different purpose. So, it is not wise to compare each other as the contenders.

What is Spring Boot?

Spring Boot is a framework for packaging the spring application with sensible defaults. What does this mean?. You are developing a web application using Spring MVC, Spring Data, Hibernate and Tomcat. How do you package and deploy this application to your web server. As of now, we have to manually write the configurations, XML files, etc. for deploying to web server.

Spring Boot does that for you with Zero XML configuration in your project. Believe me, you don't need deployment descriptor, web server, etc. Spring Boot is magical framework that bundles all the dependencies for you. Finally your web application will be a standalone JAR file with embeded servers.

If you are still confused how this works, please read about microservice framework development using spring boot.

What is Spring MVC?

It is a traditional web application framework that helps you to build web applications. It is similar to Struts framework.

A Spring MVC is a Java framework which is used to build web applications. It follows the Model-View-Controller design pattern. It implements all the basic features of a core spring framework like Inversion of Control, Dependency Injection.

A Spring MVC provides an elegant solution to use MVC in spring framework by the help of DispatcherServlet. Here, DispatcherServlet is a class that receives the incoming request and maps it to the right resource such as controllers, models, and views.

I hope this helps you to understand the difference.

I don't why you would put a<p>element there. But another way of removing spaces in between the paragraphs is by declaring only one paragraph

<ul>
   <p><li>HI THERE</li>
    <br>
    <li>ME</li>
     </p>
   </ul>

I tried lots of method but below work like charm....

After this command run these :-

curl -sL https://deb.nodesource.com/setup_14.x 565 | sudo -E bash -
sudo apt-get install -y nodejs

Now check…

node -v
npm -v

You may use pip for that without using the network. See in the docs (search for "Install a particular source archive file"). Any of those should work:

pip install relative_path_to_seaborn.tar.gz    
pip install absolute_path_to_seaborn.tar.gz    
pip install file:///absolute_path_to_seaborn.tar.gz    

Or you may uncompress the archive and use setup.py directly with either pip or python:

cd directory_containing_tar.gz
tar -xvzf seaborn-0.10.1.tar.gz
pip install seaborn-0.10.1
python setup.py install

Of course, you should also download required packages and install them the same way before you proceed.

The \n largely works for us, but Outlook does sometimes take it upon itself to remove the line breaks as you say.

Alternatively, you can use the GitHub project ts-deepcopy, which is also available on npm, to clone your object, or just include the code snippet below.

/**
 * Deep copy function for TypeScript.
 * @param T Generic type of target/copied value.
 * @param target Target value to be copied.
 * @see Source project, ts-deepcopy https://github.com/ykdr2017/ts-deepcopy
 * @see Code pen https://codepen.io/erikvullings/pen/ejyBYg
 */
export const deepCopy = <T>(target: T): T => {
  if (target === null) {
    return target;
  }
  if (target instanceof Date) {
    return new Date(target.getTime()) as any;
  }
  if (target instanceof Array) {
    const cp = [] as any[];
    (target as any[]).forEach((v) => { cp.push(v); });
    return cp.map((n: any) => deepCopy<any>(n)) as any;
  }
  if (typeof target === 'object' && target !== {}) {
    const cp = { ...(target as { [key: string]: any }) } as { [key: string]: any };
    Object.keys(cp).forEach(k => {
      cp[k] = deepCopy<any>(cp[k]);
    });
    return cp as T;
  }
  return target;
};

If you have several figures or subplots that you want to modify, it can be helpful to use the matplotlib context manager to change the color, instead of changing each one individually. The context manager allows you to temporarily change the rc parameters only for the immediately following indented code, but does not affect the global rc parameters.

This snippet yields two figures, the first one with modified colors for the axis, ticks and ticklabels, and the second one with the default rc parameters.

import matplotlib.pyplot as plt
with plt.rc_context({'axes.edgecolor':'orange', 'xtick.color':'red', 'ytick.color':'green', 'figure.facecolor':'white'}):
    # Temporary rc parameters in effect
    fig, (ax1, ax2) = plt.subplots(1,2)
    ax1.plot(range(10))
    ax2.plot(range(10))
# Back to default rc parameters
fig, ax = plt.subplots()
ax.plot(range(10))

You can type plt.rcParams to view all available rc parameters, and use list comprehension to search for keywords:

# Search for all parameters containing the word 'color'
[(param, value) for param, value in plt.rcParams.items() if 'color' in param]

My version of luvlss's command:

Mac OSX 10.10.5

MySQL 5.6.27

Passenger 5.0.21

sudo ln -s /usr/local/mysql-5.6.27-osx10.8-x86_64/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

If you're trying lots of different links, like I did, do some clean-up with:

sudo unlink /usr/lib/libmysqlclient.18.dylib

My specific case has the following scenario. Our tests

public class VenueResourceContainerTest extends BaseTixContainerTest

all extend

BaseTixContainerTest

and JUnit was trying to run BaseTixContainerTest. Poor BaseTixContainerTest was just trying to setup the container, setup the client, order some pizza and relax... man.

As mentioned previously, you can annotate the class with

@Ignore

But that caused JUnit to report that test as skipped (as opposed to completely ignored).

Tests run: 4, Failures: 0, Errors: 0, Skipped: 1

That kind of irritated me.

So I made BaseTixContainerTest abstract, and now JUnit truly ignores it.

Tests run: 3, Failures: 0, Errors: 0, Skipped: 0

The REPL makes it easy to learn APIs. Just run python, create an object and then ask for help:

$ python
>>> import re
>>> help(re.compile(r''))

at the command line shows, among other things:

search(...)

search(string[, pos[, endpos]]) --> match object or None. Scan through string looking for a match, and return a corresponding MatchObject instance. Return None if no position in the string matches.

so you can do

regex = re.compile(regex_txt, re.IGNORECASE)

match = regex.search(content)  # From your file reading code.
if match is not None:
  # use match

Incidentally,

regex_txt = "facebook.com"

has a . which matches any character, so re.compile("facebook.com").search("facebookkcom") is not None is true because . matches any character. Maybe

regex_txt = r"(?i)facebook\.com"

The \. matches a literal "." character instead of treating . as a special regular expression operator.

The r"..." bit means that the regular expression compiler gets the escape in \. instead of the python parser interpreting it.

The (?i) makes the regex case-insensitive like re.IGNORECASE but self-contained.

If you commit it, you could also cherry-pick the single commit ID. I do this often when I start work in master, and then want to create a local branch before I push up to my origin/.

git cherry-pick <commitID>

There is alot you can do with cherry-pick, as described here, but this could be a use-case for you.

You should add namespace if you are not using it:

System.Windows.Forms.MessageBox.Show("Some text", "Some title", 
    System.Windows.Forms.MessageBoxButtons.OK, 
    System.Windows.Forms.MessageBoxIcon.Error);

Alternatively, you can add at the begining of your file:

using System.Windows.Forms

and then use (as stated in previous answers):

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

git isn't a centralized scm like svn so you have two options:

• Use the web interface of target platforms (f.e. GitHub REST API or GitLab REST API)
• Download the repository and display logs locally

It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.

An example with fetching into a temporary directory:

git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline

Alternatively:

git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master

Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.

An example with GitHub:

GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3

An example with GitLab:

GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3

Both are really fast but have different interfaces (like every platform).

• When you use .getClass().getResource(fileName) it considers the location of the fileName is the same location of the of the calling class.
• When you use .getClass().getClassLoader().getResource(fileName) it considers the location of the fileName is the root - in other words bin folder.

Source :

package Sound;
public class ResourceTest {
    public static void main(String[] args) {
        String fileName = "Kalimba.mp3";
        System.out.println(fileName);
        System.out.println(new ResourceTest().getClass().getResource(fileName));
        System.out.println(new ResourceTest().getClass().getClassLoader().getResource(fileName));
    }
}

Output :

Kalimba.mp3
file:/C:/Users/User/Workspaces/MyEclipse%208.5/JMplayer/bin/Sound/Kalimba.mp3
file:/C:/Users/User/Workspaces/MyEclipse%208.5/JMplayer/bin/Kalimba.mp3

Another alternative is KMP (Knuth–Morris–Pratt).

The KMP algorithm searches for a length-m substring in a length-n string in worst-case O(n+m) time, compared to a worst-case of O(n·m) for the naive algorithm, so using KMP may be reasonable if you care about worst-case time complexity.

Here's a JavaScript implementation by Project Nayuki, taken from https://www.nayuki.io/res/knuth-morris-pratt-string-matching/kmp-string-matcher.js:

// Searches for the given pattern string in the given text string using the Knuth-Morris-Pratt string matching algorithm.
// If the pattern is found, this returns the index of the start of the earliest match in 'text'. Otherwise -1 is returned.

function kmpSearch(pattern, text) {_x000D_
  if (pattern.length == 0)_x000D_
    return 0; // Immediate match_x000D_
_x000D_
  // Compute longest suffix-prefix table_x000D_
  var lsp = [0]; // Base case_x000D_
  for (var i = 1; i < pattern.length; i++) {_x000D_
    var j = lsp[i - 1]; // Start by assuming we're extending the previous LSP_x000D_
    while (j > 0 && pattern.charAt(i) != pattern.charAt(j))_x000D_
      j = lsp[j - 1];_x000D_
    if (pattern.charAt(i) == pattern.charAt(j))_x000D_
      j++;_x000D_
    lsp.push(j);_x000D_
  }_x000D_
_x000D_
  // Walk through text string_x000D_
  var j = 0; // Number of chars matched in pattern_x000D_
  for (var i = 0; i < text.length; i++) {_x000D_
    while (j > 0 && text.charAt(i) != pattern.charAt(j))_x000D_
      j = lsp[j - 1]; // Fall back in the pattern_x000D_
    if (text.charAt(i) == pattern.charAt(j)) {_x000D_
      j++; // Next char matched, increment position_x000D_
      if (j == pattern.length)_x000D_
        return i - (j - 1);_x000D_
    }_x000D_
  }_x000D_
  return -1; // Not found_x000D_
}_x000D_
_x000D_
console.log(kmpSearch('ays', 'haystack') != -1) // true_x000D_
console.log(kmpSearch('asdf', 'haystack') != -1) // false

This is a function based on @DamienFennelly's answer above. If you give me a thumbs up, give him a thumbs up too! :P

Function outColLetterFromNumber(iCol as Integer) as String
    sAddr = Cells(1, iCol).Address
    aSplit = Split(sAddr, "$")
    outColLetterFromNumber = aSplit(1)
End Function

ETA 24 Apr 17 I wanted to simplify this a bit with some async/await magic, as it makes it a lot more succinct:

Using the same promisified-observable:

const startObservable = (domNode) => {
  var targetNode = domNode;

  var observerConfig = {
    attributes: true,
    childList: true,
    characterData: true
  };

  return new Promise((resolve) => {
      var observer = new MutationObserver(function (mutations) {
         // For the sake of...observation...let's output the mutation to console to see how this all works
         mutations.forEach(function (mutation) {
             console.log(mutation.type);
         });
         resolve(mutations)
     });
     observer.observe(targetNode, observerConfig);
   })
} 

Your calling function can be as simple as:

const waitForMutation = async () => {
    const button = document.querySelector('.some-button')
    if (button !== null) button.click()
    try {
      const results = await startObservable(someDomNode)
      return results
    } catch (err) { 
      console.error(err)
    }
}

If you wanted to add a timeout, you could use a simple Promise.race pattern as demonstrated here:

const waitForMutation = async (timeout = 5000 /*in ms*/) => {
    const button = document.querySelector('.some-button')
    if (button !== null) button.click()
    try {

      const results = await Promise.race([
          startObservable(someDomNode),
          // this will throw after the timeout, skipping 
          // the return & going to the catch block
          new Promise((resolve, reject) => setTimeout(
             reject, 
             timeout, 
             new Error('timed out waiting for mutation')
          )
       ])
      return results
    } catch (err) { 
      console.error(err)
    }
}

Original

You can do this without libraries, but you'd have to use some ES6 stuff, so be cognizant of compatibility issues (i.e., if your audience is mostly Amish, luddite or, worse, IE8 users)

First, we'll use the MutationObserver API to construct an observer object. We'll wrap this object in a promise, and resolve() when the callback is fired (h/t davidwalshblog)david walsh blog article on mutations:

const startObservable = (domNode) => {
    var targetNode = domNode;

    var observerConfig = {
        attributes: true,
        childList: true,
        characterData: true
    };

    return new Promise((resolve) => {
        var observer = new MutationObserver(function (mutations) {
            // For the sake of...observation...let's output the mutation to console to see how this all works
            mutations.forEach(function (mutation) {
                console.log(mutation.type);
            });
            resolve(mutations)
        });
        observer.observe(targetNode, observerConfig);
    })
} 

Then, we'll create a generator function. If you haven't used these yet, then you're missing out--but a brief synopsis is: it runs like a sync function, and when it finds a yield <Promise> expression, it waits in a non-blocking fashion for the promise to be fulfilled (Generators do more than this, but this is what we're interested in here).

// we'll declare our DOM node here, too
let targ = document.querySelector('#domNodeToWatch')

function* getMutation() {
    console.log("Starting")
    var mutations = yield startObservable(targ)
    console.log("done")
}

A tricky part about generators is they don't 'return' like a normal function. So, we'll use a helper function to be able to use the generator like a regular function. (again, h/t to dwb)

function runGenerator(g) {
    var it = g(), ret;

    // asynchronously iterate over generator
    (function iterate(val){
        ret = it.next( val );

        if (!ret.done) {
            // poor man's "is it a promise?" test
            if ("then" in ret.value) {
                // wait on the promise
                ret.value.then( iterate );
            }
            // immediate value: just send right back in
            else {
                // avoid synchronous recursion
                setTimeout( function(){
                    iterate( ret.value );
                }, 0 );
            }
        }
    })();
}

Then, at any point before the expected DOM mutation might happen, simply run runGenerator(getMutation).

Now you can integrate DOM mutations into a synchronous-style control flow. How bout that.

I used this to retrieve data from MySql Database:

AccessText a = new AccessText();    
a.Text=reader[1].ToString();       // MySql reader
a.Width = 70;
a.TextWrapping = TextWrapping.WrapWithOverflow;
labels[i].Content = a;

Project Files Services Tabls

go files tabs

drag drop file to libs files hover.

return project tabs and what are you see :)

#header {
margin: 0;
padding: 0;
width: 100%;
background: xxxx;
}

#header #content {
margin: 0px auto;
width: 800px; /* or whatever */
}

<div id="header">
<div id="content">
stuff here
</div>
</div>

You could do something like this:

//outside of main
namespace A
{
    enum A
    {
        a = 0,
        b = 69,
        c = 666
    };
};

//in main:

A::A a = A::c;
std::cout << a << std::endl;

Plain javascript: document.location = 'http://www.google.com';

This will cause a browser refresh though - consider using hashes if you're in need of having the URL updated to implement some kind of browsing history without reloading the page. You might want to look into jQuery.hashchange if this is the case.

Yes, divs and CSS are usually a better and easier way to place your HTML. There are many different ways to do this and it all depends on the context.

For instance, if you want to place an image to the right of your text, you could do it like so:

<p style="width: 500px;">
<img src="image.png" style="float: right;" />
This is some text
</p> 

And if you want to display multiple items side by side, float is also usually preferred.For example:

<div>
  <img src="image1.png" style="float: left;" />
  <img src="image2.png" style="float: left;" />
  <img src="image3.png" style="float: left;" />
</div>

Floating these images to the same side will have then laying next to each other for as long as you hava horizontal space.

GCD needs a little correction for negative numbers:

def gcd(x,y):
  while y:
    if y<0:
      x,y=-x,-y
    x,y=y,x % y
    return x

def gcdl(*list):
  return reduce(gcd, *list)

def lcm(x,y):
  return x*y / gcd(x,y)

def lcml(*list):
  return reduce(lcm, *list)

For some reason John Rees' answer sometimes did not work in my case. But it led me in the following direction. First I try to delete the directory recursively with the buggy -recurse option. Afterwards I descend into every subdir that's left and delete all files.

function Remove-Tree($Path)
{ 
    Remove-Item $Path -force -Recurse -ErrorAction silentlycontinue

    if (Test-Path "$Path\" -ErrorAction silentlycontinue)
    {
        $folders = Get-ChildItem -Path $Path –Directory -Force
        ForEach ($folder in $folders)
        {
            Remove-Tree $folder.FullName
        }

        $files = Get-ChildItem -Path $Path -File -Force

        ForEach ($file in $files)
        {
            Remove-Item $file.FullName -force
        }

        if (Test-Path "$Path\" -ErrorAction silentlycontinue)
        {
            Remove-Item $Path -force
        }
    }
}

If you want to group the results based on a column and take the count based on the same, you can run the query as,

$sql = "SELECT COLUMNNAME,

COUNT(CASE WHEN COLUMNNAME IN ('YOURCONDITION') then 1 ELSE NULL END) as 'New',

COUNT(CASE WHEN COLUMNNAME IN ('YOURCONDITION') then 1 ELSE NULL END) as 'ACCPTED',

from TABLENAME

GROUP BY COLUMNANME";

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE
----------- ---------- -------------- ---------
          1 HSBC       Nugegoda Road      43434
          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10
column address format a20
column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;

Using mongoose.js you can count documents,

• count all

const count = await Schema.countDocuments();

• count specific

const count = await Schema.countDocuments({ key: value });

<%= Html.Partial("PartialName", Model) %>

The cause of the error is the use of the internal PHP programming data structures function, array_shift() [php.net/end].

The function takes an array as a parameter. Although an ampersand is indicated in the prototype of array_shift() in the manual", there isn't any cautionary documentation following in the extended definition of that function, nor is there any apparent explanation that the parameter is in fact passed by reference.

Perhaps this is /understood/. I did not understand, however, so it was difficult for me to detect the cause of the error.

Reproduce code:

function get_arr()
{
    return array(1, 2);
}
$array = get_arr();
$el = array_shift($array);

The following function splits the string and returns the name and extension no matter how many dots there are in the extension. It returns an empty string for the extension if there is none. Names that start with dots and/or white space work also.

function basext(name) {
  name = name.trim()
  const match = name.match(/^(\.+)/)
  let prefix = ''
  if (match) {
    prefix = match[0]
    name = name.replace(prefix, '')
  }
  const index = name.indexOf('.')
  const ext = name.substring(index + 1)
  const base = name.substring(0, index) || ext
  return [prefix + base, base === ext ? '' : ext]
}

const [base, ext] = basext('hello.txt')

To have an output more similar to the raw console.log(obj) I usually do use console.log('Status: ' + util.inspect(obj)) (JSON is slightly different).

Try the following code. The value you are looking for is stored on a GuidAttribute instance attached to the Assembly

using System.Runtime.InteropServices;

static void Main(string[] args)
{
    var assembly = typeof(Program).Assembly;
    var attribute = (GuidAttribute)assembly.GetCustomAttributes(typeof(GuidAttribute),true)[0];
    var id = attribute.Value;
    Console.WriteLine(id);
}

I prefer to use a looping variable, as it tends to read a bit nicer than just "while 1:", and no ugly-looking break statement:

finished = False
while not finished:
    ... do something...
    finished = evaluate_end_condition()

The simplest way is to use the following pattern:

http://[server]/[site]/[ListName]/[Folder]/[SubFolder]

To place a shortcut to a document library:

1. Upload it as *.url file. However, by default, this file type is not allowed.
2. Go to you Document Library settings > Advanced Settings > Allow management of content types. Add the "Link to document" content type to a document library and paste the link

Note that since May 2013 ("Repository redirects are here!"), you can rename your GitHub repo without breaking any links:

We're happy to announce that starting today, we'll automatically redirect all requests for previous repository locations to their new home in these circumstances. There's nothing special you have to do. Just rename away and we'll take care of the rest.

As a special bonus, we'll also be servicing all Git clone, fetch, and push requests from previous repository locations.

That means you don't even have to git remote set-url (change the url of your remote GitHub repo) on your local cloned repo!
Although Gabriel notes in the comments that the official GitHub help page strongly recommends that you do so:

to reduce confusion, we strongly recommend updating any existing local clones to point to the new repository URL. You can do this by using git remote on the command line:

git remote set-url origin new_url

Beware though:

GitHub Pages sites are not automatically redirected when their repositories are renamed at this time.
Renaming a Pages repository will continue to break any existing links to content hosted on the github.io domain or custom domains.

Plus, the user still owns the namespace: if he/she creates a new repo using the old name of the renamed repo, that redirection (for said renamed repo) will stop working.

render: function(){
     return(
         <div>
           <input type="text" id="one" onKeyDown={this.add} />
        </div>
     );
}

onKeyDown detects keyCode events.

The accepted answer from @arshajii is totally correct. However just being more explicit by saying below,

StringUtils.isBlank()

 StringUtils.isBlank(null)      = true
 StringUtils.isBlank("")        = true  
 StringUtils.isBlank(" ")       = true  
 StringUtils.isBlank("bob")     = false  
 StringUtils.isBlank("  bob  ") = false

StringUtils.isEmpty

 StringUtils.isEmpty(null)      = true
 StringUtils.isEmpty("")        = true  
 StringUtils.isEmpty(" ")       = false  
 StringUtils.isEmpty("bob")     = false  
 StringUtils.isEmpty("  bob  ") = false

Using Numpy's fancy indexing:

>>> test
array([ 1, 23,  4,  6,  7,  8])

>>> test[::-1]  # test, reversed
array([ 8,  7,  6,  4, 23,  1])

>>> numpy.vstack([test, test[::-1]])  # stack test and its reverse
array([[ 1, 23,  4,  6,  7,  8],
       [ 8,  7,  6,  4, 23,  1]])

>>> # transpose, then take the first half;
>>> # +1 to cater to odd-length arrays
>>> numpy.vstack([test, test[::-1]]).T[:(len(test) + 1) // 2]
array([[ 1,  8],
       [23,  7],
       [ 4,  6]])

vstack copies the array, but all the other operations are constant-time pointer tricks (including reversal) and hence are very fast.

A possible CSS ONLY solution can be achived with position: sticky;

The browser support is actually really good: https://caniuse.com/#search=position%3A%20sticky

here is an example: https://jsfiddle.net/0vcoa43L/7/

No.

If the user is sophisticated or determined enough to:

1. Open the Excel VBA editor
2. Use the object browser to see the list of all sheets, including VERYHIDDEN ones
3. Change the property of the sheet to VISIBLE or just HIDDEN

then they are probably sophisticated or determined enough to:

1. Search the internet for "remove Excel 2007 project password"
2. Apply the instructions they find.

So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.

We use a series of static methods to pull all of the values out of our data readers. So in this case we'd be calling DBUtils.GetString(sqlreader(indexFirstName)) The benefit of creating static/shared methods is that you don't have to do the same checks over and over and over...

The static method(s) would contain code to check for nulls (see other answers on this page).

We can hide the content inside a by using the following inline css:

<div style="visibility:hidden"></div>

for example:

<td><div style="visibility:hidden">Your Content Goes Here:</div></td>

WORKING ALWAYS ON TOP IMAGE BUTTON

first of all sorry for my english

i edit your codes and make working image button that listens his touch event do not give touch control to his background elements.

also it gives touch listeners to out of other elements

button alingments are bottom and left

you can chage alingments but you need to chages cordinats in touch event in the if element

Updated Answer for Express 4.x

Rather than using res.send(404) as in old versions of Express, the new method is:

res.sendStatus(404);

Express will send a very basic 404 response with "Not Found" text:

HTTP/1.1 404 Not Found
X-Powered-By: Express
Vary: Origin
Content-Type: text/plain; charset=utf-8
Content-Length: 9
ETag: W/"9-nR6tc+Z4+i9RpwqTOwvwFw"
Date: Fri, 23 Oct 2015 20:08:19 GMT
Connection: keep-alive

Not Found

        textBox1.Enabled = false;

"false" property will make the text box disable. and "true" will make it in regular form. Thanks.

If you want to stick with the same sort of loop then this will work:

Option Explicit

Sub selectColumns()

Dim topSelection As Integer
Dim endSelection As Integer
topSelection = 2
endSelection = 10

Dim columnSelected As Integer

Do
   With Excel.ThisWorkbook.ActiveSheet
        .Range(.Cells(columnSelected, columnSelected), .Cells(endSelection, columnSelected)).Select
   End With
   columnSelected = columnSelected + 1
Loop Until columnSelected > 10

End Sub

EDIT

If in reality you just want to loop through every cell in an area of the spreadsheet then use something like this:

Sub loopThroughCells()

'=============
'this is the starting point
Dim rwMin As Integer
Dim colMin As Integer
rwMin = 2
colMin = 2
'=============

'=============
'this is the ending point
Dim rwMax As Integer
Dim colMax As Integer
rwMax = 10
colMax = 5
'=============

'=============
'iterator
Dim rwIndex As Integer
Dim colIndex As Integer
'=============

For rwIndex = rwMin To rwMax
        For colIndex = colMin To colMax
            Cells(rwIndex, colIndex).Select
        Next colIndex
Next rwIndex

End Sub

Strictly,

other = s if s is not None else "default value"

Otherwise, s = False will become "default value", which may not be what was intended.

If you want to make this shorter, try:

def notNone(s,d):
    if s is None:
        return d
    else:
        return s

other = notNone(s, "default value")

Hmm..i tried everything to get url to user image.The perfect solution was fql use like this->

    $fql_b = 'SELECT pic from user where uid = ' . $user_id;
    $ret_obj_b = $facebook->api(array(
                               'method' => 'fql.query',
                               'query' => $fql_b,
                             ));


             $dp_url =$ret_obj_b[0]['pic'];

replace pic by big,pic_square to get other desired results. Hope IT HELPED....

I am not sure will this be useful for anyone, since I had to provide other users of the system to schedule the jobs, without giving them access to the actual server(windows) Task Scheduler, I created this reusable app.

Please note users have access to one shared folder on server where they can create required command/task/.bat file. This task then can be scheduled using this app.

App name is Django_Windows_Scheduler

ScreenShot:

What about:

git checkout old-branch-name
git push remote-name new-branch-name
git push remote-name :old-branch-name
git branch -m new-branch-name

string originalSting = "This is my string";
string texttobesearched = "my";
string dataAfterTextTobeSearch= finalCommand.Split(new string[] { texttobesearched     }, StringSplitOptions.None).Last();
if(dataAfterTextobeSearch!=originalSting)
{
    //your action here if data is found
}
else
{
    //action if the data being searched was not found
}

UTF-16 Byte Array

JavaScript encodes strings as UTF-16, just like C#'s UnicodeEncoding, so the byte arrays should match exactly using charCodeAt(), and splitting each returned byte pair into 2 separate bytes, as in:

function strToUtf16Bytes(str) {
  const bytes = [];
  for (ii = 0; ii < str.length; ii++) {
    const code = str.charCodeAt(ii); // x00-xFFFF
    bytes.push(code & 255, code >> 8); // low, high
  }
  return bytes;
}

For example:

strToUtf16Bytes(''); 
// [ 60, 216, 53, 223 ]

However, If you want to get a UTF-8 byte array, you must transcode the bytes.

UTF-8 Byte Array

The solution feels somewhat non-trivial, but I used the code below in a high-traffic production environment with great success (original source).

Also, for the interested reader, I published my unicode helpers that help me work with string lengths reported by other languages such as PHP.

/**
 * Convert a string to a unicode byte array
 * @param {string} str
 * @return {Array} of bytes
 */
export function strToUtf8Bytes(str) {
  const utf8 = [];
  for (let ii = 0; ii < str.length; ii++) {
    let charCode = str.charCodeAt(ii);
    if (charCode < 0x80) utf8.push(charCode);
    else if (charCode < 0x800) {
      utf8.push(0xc0 | (charCode >> 6), 0x80 | (charCode & 0x3f));
    } else if (charCode < 0xd800 || charCode >= 0xe000) {
      utf8.push(0xe0 | (charCode >> 12), 0x80 | ((charCode >> 6) & 0x3f), 0x80 | (charCode & 0x3f));
    } else {
      ii++;
      // Surrogate pair:
      // UTF-16 encodes 0x10000-0x10FFFF by subtracting 0x10000 and
      // splitting the 20 bits of 0x0-0xFFFFF into two halves
      charCode = 0x10000 + (((charCode & 0x3ff) << 10) | (str.charCodeAt(ii) & 0x3ff));
      utf8.push(
        0xf0 | (charCode >> 18),
        0x80 | ((charCode >> 12) & 0x3f),
        0x80 | ((charCode >> 6) & 0x3f),
        0x80 | (charCode & 0x3f),
      );
    }
  }
  return utf8;
}

For me none of the previous answers worked. I had to copy .gitignore text into the exclude.txt file found at

<Your-project-folder>\.git\info

Once done, refresh your changes and all the untracked files are gone. Commit as usual.

The most effective solution that I found is to define the parent element with display:flex and align-items:center

LIVE DEMO

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <style>
      .myclass{
        display:flex;
        align-items:center;
        background-color:grey;
        color:#fff;
        height:50px;
      }
    </style>
  </head>
  <body>
    <div class="myclass">
      <input type="checkbox">
      <label>do you love Ananas?
      </label>
    </div>
  </body>
</html>

OUTPUT:

To my knowledge the only way to achieve this in a native select would be to use the unicode representations of the font. You'll have to apply the glyphicon font to the select and as such can't mix it with other fonts. However, glyphicons include regular characters, so you can add text. Unfortunately setting the font for individual options doesn't seem to be possible.

<select class="form-control glyphicon">
    <option value="">&#x2212; &#x2212; &#x2212; Hello</option>
    <option value="glyphicon-list-alt">&#xe032; Text</option>
</select>

Here's a list of the icons with their unicode:

http://glyphicons.bootstrapcheatsheets.com/

export PGPASSWORD=<password>
psql -h <host> -d <database> -U <user_name> -p <port> -a -w -f <file>.sql

You can use show innodb status (or show engine innodb status for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.

You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.

Here's what you'd want to look for:

------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status

In this case, there's just one connection to the InnoDB engine right now (my login, running the show query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594.

You can use WMIC or SCHTASKS (which means no third party software is needed):

1) SCHTASKS:

SCHTASKS /s remote_machine /U username /P password /create /tn "On demand demo" /tr "C:\some.bat" /sc ONCE /sd 01/01/1910 /st 00:00
SCHTASKS /s remote_machine /U username /P password /run /TN "On demand demo" 

2) WMIC (wmic will return the pid of the started process)

WMIC /NODE:"remote_machine" /user user /password password process call create "c:\some.bat","c:\exec_dir"

                int padding = (int) (width * 0.15); // offset from edges of the map 10% of screen

                CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, width, height, padding);

                mMap.animateCamera(cu);

I hope this can help you!

Thank You.

URLs can give a lot of clues, especially with Content Management Systems.

For example "http://abcxyz.com/node/46" looks a lot like Drupal.

Also many frameworks have standard JavaScript and CSS files they use.

In SQL Server 2016 it has its own link:

Just download it here: https://msdn.microsoft.com/en-us/library/mt238290.aspx

document.cookie = "cookiename=Some Name; path=/";

This will do

For using Git bash on Windows:

cat ~/.ssh/id_rsa.pub > /dev/clipboard

(modified from Jupiter St John's post on Coderwall)

This is how you do it

SELECT ID,NAME, (C_COUNTS+F_COUNTS) AS SUM_COUNTS 
FROM TABLE 
ORDER BY SUM_COUNTS LIMIT 20

The SUM function will add up all rows, so the order by clause is useless, instead you will have to use the group by clause.

In my case I have two activities. In the second activity I forgot to put super on the onCreate method.

super.onCreate(savedInstanceState);

Please, see this answer: https://stackoverflow.com/a/3863869/2096619

Quoting Tamlyn:

jQuery (1.4.2) gets confused if you have any form elements named "action". You can get around this by using the DOM attribute methods or simply avoid having form elements named "action".

<form action="foo">
  <button name="action" value="bar">Go</button>
</form>

<script type="text/javascript">
  $('form').attr('action', 'baz'); //this fails silently
  $('form').get(0).setAttribute('action', 'baz'); //this works
</script>

That's not how you send file on postman. What you did is sending a string which is the path of your image, nothing more.

What you should do is;

1. After setting request method to POST, click to the 'body' tab.
2. Select form-data. At first line, you'll see text boxes named key and value. Write 'image' to the key. You'll see value type which is set to 'text' as default. Make it File and upload your file.
3. Then select 'raw' and paste your json file. Also just next to the binary choice, You'll see 'Text' is clicked. Make it JSON.

You're ready to go.

In your Django view,

from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
from rest_framework.decorators import parser_classes

@parser_classes((MultiPartParser, ))
class UploadFileAndJson(APIView):

    def post(self, request, format=None):
        thumbnail = request.FILES["file"]
        info = json.loads(request.data['info'])
        ...
        return HttpResponse()

According to the man page of wget, there are a couple of options related to timeouts -- and there is a default read timeout of 900s -- so I say that, yes, it could timeout.

Here are the options in question :

-T seconds
--timeout=seconds

Set the network timeout to seconds seconds. This is equivalent to specifying --dns-timeout, --connect-timeout, and --read-timeout, all at the same time.

And for those three options :

--dns-timeout=seconds

Set the DNS lookup timeout to seconds seconds.
DNS lookups that don't complete within the specified time will fail.
By default, there is no timeout on DNS lookups, other than that implemented by system libraries.

--connect-timeout=seconds

Set the connect timeout to seconds seconds.
TCP connections that take longer to establish will be aborted.
By default, there is no connect timeout, other than that implemented by system libraries.

--read-timeout=seconds

Set the read (and write) timeout to seconds seconds.
The "time" of this timeout refers to idle time: if, at any point in the download, no data is received for more than the specified number of seconds, reading fails and the download is restarted.
This option does not directly affect the duration of the entire download.

I suppose using something like

wget -O - -q -t 1 --timeout=600 http://www.example.com/cron/run

should make sure there is no timeout before longer than the duration of your script.

(Yeah, that's probably the most brutal solution possible ^^ )

    */

You have a constructor which takes 2 parameters. You should write something like:

new ErrorEventArg(errorMsv, lastQuery)

It's less code and easier to read.

EDIT

Or, in order for your way to work, you can try writing a default constructor for ErrorEventArg which would have no parameters, like this:

public ErrorEventArg() {}

Suppose you have less data, I suggest to try 70%, 80% and 90% and test which is giving better result. In case of 90% there are chances that for 10% test you get poor accuracy.

The following solution bypasses the automatic exponentional formatting for very big and very small numbers. This is outis's solution with a bugfix: It was not working for very small negative numbers.

For example: your bean class name is UserDetails

Query query = entityManager. createQuery("Select UserName from **UserDetails** "); 

You do not give your table name on the Db. you give the class name of bean.

private double ConvertToDouble(string s)
    {
        char systemSeparator = Thread.CurrentThread.CurrentCulture.NumberFormat.CurrencyDecimalSeparator[0];
        double result = 0;
        try
        {
            if (s != null)
                if (!s.Contains(","))
                    result = double.Parse(s, CultureInfo.InvariantCulture);
                else
                    result = Convert.ToDouble(s.Replace(".", systemSeparator.ToString()).Replace(",", systemSeparator.ToString()));
        }
        catch (Exception e)
        {
            try
            {
                result = Convert.ToDouble(s);
            }
            catch
            {
                try
                {
                    result = Convert.ToDouble(s.Replace(",", ";").Replace(".", ",").Replace(";", "."));
                }
                catch {
                    throw new Exception("Wrong string-to-double format");
                }
            }
        }
        return result;
    }

and successfully passed tests are:

        Debug.Assert(ConvertToDouble("1.000.007") == 1000007.00);
        Debug.Assert(ConvertToDouble("1.000.007,00") == 1000007.00);
        Debug.Assert(ConvertToDouble("1.000,07") == 1000.07);
        Debug.Assert(ConvertToDouble("1,000,007") == 1000007.00);
        Debug.Assert(ConvertToDouble("1,000,000.07") == 1000000.07);
        Debug.Assert(ConvertToDouble("1,007") == 1.007);
        Debug.Assert(ConvertToDouble("1.07") == 1.07);
        Debug.Assert(ConvertToDouble("1.007") == 1007.00);
        Debug.Assert(ConvertToDouble("1.000.007E-08") == 0.07);
        Debug.Assert(ConvertToDouble("1,000,007E-08") == 0.07);

The following works in bash:

I=0

for N in `cat numbers.txt`
do
    I=`expr $I + $N`
done

echo $I

SELECT DISTINCT C.valueC 
FROM C 
  LEFT JOIN B ON C.id = B.lookupC
  LEFT JOIN A ON B.id = A.lookupB
WHERE C.id IS NOT NULL

I don't see a good reason why you want to limit the result sets of A and B because what you want to have is a list of all C's that are referenced by A. I did a distinct on C.valueC because i guessed you wanted a unique list of C's.

EDIT: I agree with your argument. Even if your solution looks a bit nested it seems to be the best and fastest way to use your knowledge of the data and reduce the result sets.

There is no distinct join construct you could use so just stay with what you already have :)

Actually the easiest way to do that would be to pass kill arguments like below:

ps -ef | grep your_process_name | grep -v grep | awk '{print $2}' | xargs kill

Hope it helps.

Say you have a big table called orders, and a small table called customers. There is a foreign key from an order to a customer. Now if you delete a customer, Sql Server must check that there are no orphan orders; if there are, it raises an error.

To check if there are any orders, Sql Server has to search the big orders table. Now if there is an index, the search will be fast; if there is not, the search will be slow.

So in this case, the slow delete could be explained by the absence of an index. Especially if Sql Server would have to search 15 big tables without an index.

P.S. If the foreign key has ON DELETE CASCADE, Sql Server still has to search the order table, but then to remove any orders that reference the deleted customer.

:set runtimepath?

This lists the path of all plugins loaded when a file is opened with Vim.

You need to enter the width % for each cell. But wait, there's a better way to do that, it's called CSS:

<style>
     .equalDivide tr td { width:25%; }
</style>

<table class="equalDivide" cellpadding="0" cellspacing="0" width="100%" border="0">
   <tr>
      <td></td>
      <td></td>
      <td></td>
      <td></td>
   </tr>
</table>

When you define any variable then you do not have to put in any extra spaces.

E.g.

name = "Stack Overflow"  
// it is not valid, you will get an error saying- "Command not found"

So remove spaces:

name="Stack Overflow" 

and it will work fine.

In order to prove that a problem L is NP-complete, we need to do the following steps:

1. Prove your problem L belongs to NP (that is that given a solution you can verify it in polynomial time)
2. Select a known NP-complete problem L'
3. Describe an algorithm f that transforms L' into L
4. Prove that your algorithm is correct (formally: x ? L' if and only if f(x) ? L )
5. Prove that algo f runs in polynomial time

Hi all, I was able to achieve 'Detect Browser and Tab Close Event' clicks by using browser local storage and timestamp. Hope all of you will get solved your problems by using this solution.

After my initial research i found that when we close a browser, the browser will close all the tabs one by one to completely close the browser. Hence, i observed that there will be very little time delay between closing the tabs. So I taken this time delay as my main validation point and able to achieve the browser and tab close event detection.

I tested it on Chrome Browser Version 76.0.3809.132 and found working

I came here looking for an answer to this same question and none of the answers above actually answer the question at all!

So after some investigation I found out: there is a package (for python 3.x at least):

pip3 install pytk

The problem is, it is only the python part of the equation and doesn't install the tkinter libraries in your OS, so the answer is that you can't install it completely via pip https://tkdocs.com/tutorial/install.html

Personally I find this very annoying as i'm packaging a python application to be installed via pip that uses tkinter and I was looking for a way to have pip ensure that tkinter is installed and the answer is I can't I have to instruct users to install it if it's not installed already, a very poor experience for end users who should not need to know or care what tkinter is to use my application.

You are reading this answer says that your __init__.py is in the right place, you have installed all the dependencies and you are still getting the ImportError.

I was facing a similar issue except that my program would run fine when ran using PyCharm but the above error when I would run it from the terminal. After digging further, I found out that PYTHONPATH didn't have the entry for the project directory. So, I set PYTHONPATH per Import statement works on PyCharm but not from terminal:

export PYTHONPATH=$PYTHONPATH:`pwd`  (OR your project root directory)

There's another way to do this using sys.path as:

import sys
sys.path.insert(0,'<project directory>') OR
sys.path.append('<project directory>')

You can use insert/append based on the order in which you want your project to be searched.

xargs --arg-file inputfile cat

This will output the filename followed by the file's contents:

xargs --arg-file inputfile -I % sh -c "echo %; cat %"

Here's my version:

def getfiles(dirpath):
    a = [s for s in os.listdir(dirpath)
         if os.path.isfile(os.path.join(dirpath, s))]
    a.sort(key=lambda s: os.path.getmtime(os.path.join(dirpath, s)))
    return a

First, we build a list of the file names. isfile() is used to skip directories; it can be omitted if directories should be included. Then, we sort the list in-place, using the modify date as the key.

On Mac OS X, TextMate is a godsend.

Here is the standard formula to extract the values of attribute and text using XPath-

1. To extract attribute value for Web Element-

   elementXPath/@attributeName

2. To extract text value for Web Element-

   elementXPath/text()

In your case here is the xpath which will return

//parent[@name='Parent_1']//child/@name

It will return:

Child_2
Child_4
Child_1
Child_3

My solution is put those imports in __init__.py of lib:

in file: __init__.py
import mod1

Then,

import lib
lib.mod1

would work fine.

There is also a way to do this without loops using the DataTable.Compute Method. The following example comes from that page. You can see that the code used is pretty simple.:

private void ComputeBySalesSalesID(DataSet dataSet)
{
    // Presumes a DataTable named "Orders" that has a column named "Total."
    DataTable table;
    table = dataSet.Tables["Orders"];

    // Declare an object variable. 
    object sumObject;
    sumObject = table.Compute("Sum(Total)", "EmpID = 5");
}

I must add that if you do not need to filter the results, you can always pass an empty string:

sumObject = table.Compute("Sum(Total)", "")

You can create table script along with its data using following steps:

1. Right click on the database.
2. Select Tasks > Generate scripts ...
3. Click next.
4. Click next.
5. In Table/View Options, set Script Data to True; then click next.
6. Select the Tables checkbox and click next.
7. Select your table name and click next.
8. Click next until the wizard is done.

Try this

select to_char(SYSDATE,'Month') from dual;

for full name and try this

select to_char(SYSDATE,'Mon') from dual;

for abbreviation

Expanding on the above answer from Sean DiSanti, I think the following is a simple and elegant solution that avoids having to loop over the array and won't give false positives due to partial matches

function is_in_array {
    local ELEMENT="${1}"
    local DELIM=","
    printf "${DELIM}%s${DELIM}" "${@:2}" | grep -q "${DELIM}${ELEMENT}${DELIM}"
}

Which can be called like so:

$ haystack=("needle1" "needle2" "aneedle" "spaced needle")
$ is_in_array "needle" "${haystack[@]}"
$ echo $?
1
$ is_in_array "needle1" "${haystack[@]}"
$ echo $?
0

try this way .eregi("[^A-Za-z0-9.]", $value)

I was having "(...) unable to handle this request. http error 500" and found out it was from a require_once that was working locally, on a windows machine, with backslash (\) as separator for directories but when i uploaded to my server it stopped working. I changed it to forward slash (/) and now is ok.

require_once ( 'cards\cards.php' ); // **http error 500**

require_once ( 'cards/cards.php' ); // OK

This is maybe not the case of original OP question, but: if you exceeds the default max size, this maybe a symptom of some other issue you have. in my case, I had the warrning, but finally it turned into a FATAL ERROR: MarkCompactCollector: semi-space copy, fallback in old gen Allocation failed - JavaScript heap out of memory. the reason was that i dynamically imported the current module, so this ended up with an endless loop...

The window.open() function will also allow this if you have a reference to the window created, provided it is on the same domain. If the variable is used server side you should be using a $_SESSION variable (assuming you are using PHP).

This is a work in progress, but this is what I don't understand:

ActivityManager activityManager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE);
MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
activityManager.getMemoryInfo(memoryInfo);

Log.i(TAG, " memoryInfo.availMem " + memoryInfo.availMem + "\n" );
Log.i(TAG, " memoryInfo.lowMemory " + memoryInfo.lowMemory + "\n" );
Log.i(TAG, " memoryInfo.threshold " + memoryInfo.threshold + "\n" );

List<RunningAppProcessInfo> runningAppProcesses = activityManager.getRunningAppProcesses();

Map<Integer, String> pidMap = new TreeMap<Integer, String>();
for (RunningAppProcessInfo runningAppProcessInfo : runningAppProcesses)
{
    pidMap.put(runningAppProcessInfo.pid, runningAppProcessInfo.processName);
}

Collection<Integer> keys = pidMap.keySet();

for(int key : keys)
{
    int pids[] = new int[1];
    pids[0] = key;
    android.os.Debug.MemoryInfo[] memoryInfoArray = activityManager.getProcessMemoryInfo(pids);
    for(android.os.Debug.MemoryInfo pidMemoryInfo: memoryInfoArray)
    {
        Log.i(TAG, String.format("** MEMINFO in pid %d [%s] **\n",pids[0],pidMap.get(pids[0])));
        Log.i(TAG, " pidMemoryInfo.getTotalPrivateDirty(): " + pidMemoryInfo.getTotalPrivateDirty() + "\n");
        Log.i(TAG, " pidMemoryInfo.getTotalPss(): " + pidMemoryInfo.getTotalPss() + "\n");
        Log.i(TAG, " pidMemoryInfo.getTotalSharedDirty(): " + pidMemoryInfo.getTotalSharedDirty() + "\n");
    }
}

Why isn't the PID mapped to the result in activityManager.getProcessMemoryInfo()? Clearly you want to make the resulting data meaningful, so why has Google made it so difficult to correlate the results? The current system doesn't even work well if I want to process the entire memory usage since the returned result is an array of android.os.Debug.MemoryInfo objects, but none of those objects actually tell you what pids they are associated with. If you simply pass in an array of all pids, you will have no way to understand the results. As I understand it's use, it makes it meaningless to pass in more than one pid at a time, and then if that's the case, why make it so that activityManager.getProcessMemoryInfo() only takes an int array?

Yes, but you need to move the variable assignment into the query:

SET @user := 123456;
SELECT @group := `group` FROM user WHERE user = @user;
SELECT * FROM user WHERE `group` = @group;

Test case:

CREATE TABLE user (`user` int, `group` int);
INSERT INTO user VALUES (123456, 5);
INSERT INTO user VALUES (111111, 5);

Result:

SET @user := 123456;
SELECT @group := `group` FROM user WHERE user = @user;
SELECT * FROM user WHERE `group` = @group;

+--------+-------+
| user   | group |
+--------+-------+
| 123456 |     5 |
| 111111 |     5 |
+--------+-------+
2 rows in set (0.00 sec)

Note that for SET, either = or := can be used as the assignment operator. However inside other statements, the assignment operator must be := and not = because = is treated as a comparison operator in non-SET statements.

UPDATE:

Further to comments below, you may also do the following:

SET @user := 123456;
SELECT `group` FROM user LIMIT 1 INTO @group; 
SELECT * FROM user WHERE `group` = @group;

One useful trick in SQL is the ability use @var = function(...) to assign a value. If you have multiple records in your record set, your var is assigned multiple times with side-effects:

declare @badStrings table (item varchar(50))

INSERT INTO @badStrings(item)
SELECT '>' UNION ALL
SELECT '<' UNION ALL
SELECT '(' UNION ALL
SELECT ')' UNION ALL
SELECT '!' UNION ALL
SELECT '?' UNION ALL
SELECT '@'

declare @testString varchar(100), @newString varchar(100)

set @teststring = 'Juliet ro><0zs my s0x()rz!!?!one!@!@!@!'
set @newString = @testString

SELECT @newString = Replace(@newString, item, '') FROM @badStrings

select @newString -- returns 'Juliet ro0zs my s0xrzone'

First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).

Neither is supported by Windows command-line ftp.exe. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.

Using WinSCP, your batch file would look like (for SFTP):

echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat

And the batch file:

winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%

Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP% syntax), the batch file simplifies to:

winscp.com /log=ftpcmd.log /command ^
    "open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

For the purpose of -hostkey switch, see verifying the host key in script.

Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:

All you need to tweak is the source file name (use the %TIMESTAMP% syntax as shown previously) and the path to the log file.

For FTPS, replace the sftp:// in the open command with ftpes:// (explicit TLS/SSL) or ftps:// (implicit TLS/SSL). Remove the -hostkey switch.

winscp.com /log=ftpcmd.log /command ^
    "open ftps://ftp_user:[email protected] -explicit" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

You may need to add the -certificate switch, if your server's certificate is not issued by a trusted authority.

Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.

See a complete conversion guide from ftp.exe to WinSCP.

You should also read the Guide to automating file transfers to FTP server or SFTP server.

Note to using %TIMESTAMP#yyyymmdd% instead of %date%: A format of %date% variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date% resolves to ct 06. 11. 2014, what might be problematic when used as a part of a file name.

For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd% resolves to 20170515 on any locale.
