The following code worked for me:

echo userInput

You have pointers and values:

int* p; // variable p is pointer to integer type
int i; // integer value

You turn a pointer into a value with *:

int i2 = *p; // integer i2 is assigned with integer value that pointer p is pointing to

You turn a value into a pointer with &:

int* p2 = &i; // pointer p2 will point to the address of integer i

Edit: In the case of arrays, they are treated very much like pointers. If you think of them as pointers, you'll be using * to get at the values inside of them as explained above, but there is also another, more common way using the [] operator:

int a[2];  // array of integers
int i = *a; // the value of the first element of a
int i2 = a[0]; // another way to get the first element

To get the second element:

int a[2]; // array
int i = *(a + 1); // the value of the second element
int i2 = a[1]; // the value of the second element

So the [] indexing operator is a special form of the * operator, and it works like this:

a[i] == *(a + i);  // these two statements are the same thing

An alternative answer is to reshape the array so that it has dimensions (1, N) like so:

savetext(filename, a.reshape(1, a.shape[0]))

• hstore is more of a "wide column" storage type, it is a flat (non-nested) dictionary of key-value pairs, always stored in a reasonably efficient binary format (a hash table, hence the name).
• json stores JSON documents as text, performing validation when the documents are stored, and parsing them on output if needed (i.e. accessing individual fields); it should support the entire JSON spec. Since the entire JSON text is stored, its formatting is preserved.
• jsonb takes shortcuts for performance reasons: JSON data is parsed on input and stored in binary format, key orderings in dictionaries are not maintained, and neither are duplicate keys. Accessing individual elements in the JSONB field is fast as it doesn't require parsing the JSON text all the time. On output, JSON data is reconstructed and initial formatting is lost.

IMO, there is no significant reason for not using jsonb once it is available, if you are working with machine-readable data.

Here's a nifty trick that doesn't use a semaphore:

dispatch_queue_t serialQ = dispatch_queue_create("serialQ", DISPATCH_QUEUE_SERIAL);
dispatch_async(serialQ, ^
{
    [object doSomething];
});
dispatch_sync(serialQ, ^{ });

What you do is wait using dispatch_sync with an empty block to Synchronously wait on a serial dispatch queue until the A-Synchronous block has completed.

If you are using structured data, this has the added benefit of not invoking an extra shell process to run tr and/or cut or something. ...

(Of course, you will want to guard against bad inputs with conditionals and sane alternatives.)

...
while read line ; 
do 
    lineCols=( $line ) ;
    echo "${lineCols[0]}"
    echo "${lineCols[1]}"
done < $myFQFileToRead ; 
...

This comes in useful when you have global variables. You declare the existence of global variables in a header, so that each source file that includes the header knows about it, but you only need to “define” it once in one of your source files.

To clarify, using extern int x; tells the compiler that an object of type int called x exists somewhere. It's not the compilers job to know where it exists, it just needs to know the type and name so it knows how to use it. Once all of the source files have been compiled, the linker will resolve all of the references of x to the one definition that it finds in one of the compiled source files. For it to work, the definition of the x variable needs to have what's called “external linkage”, which basically means that it needs to be declared outside of a function (at what's usually called “the file scope”) and without the static keyword.

header:

#ifndef HEADER_H
#define HEADER_H

// any source file that includes this will be able to use "global_x"
extern int global_x;

void print_global_x();

#endif

source 1:

#include "header.h"

// since global_x still needs to be defined somewhere,
// we define it (for example) in this source file
int global_x;

int main()
{
    //set global_x here:
    global_x = 5;

    print_global_x();
}

source 2:

#include <iostream>
#include "header.h"

void print_global_x()
{
    //print global_x here:
    std::cout << global_x << std::endl;
}

Simple Working Example of Http request using node.

const http = require('https')

httprequest().then((data) => {
        const response = {
            statusCode: 200,
            body: JSON.stringify(data),
        };
    return response;
});
function httprequest() {
     return new Promise((resolve, reject) => {
        const options = {

            path: '/todos',
            port: 443,

        };
        const req = http.request(options, (res) => {

                }
                resolve(body);
            });
        });
        req.on('error', (e) => {
          reject(e.message);
        });
        // send the request
       req.end();

}

In Spring Boot 2, the easiest way is to declare in your application.properties:

spring.jackson.serialization.WRITE_ENUMS_USING_TO_STRING=true
spring.jackson.deserialization.READ_ENUMS_USING_TO_STRING=true

and define the toString() method of your enums.

In my case I had to put it in the bin folder of my project even the fact that my classpath is set to the src folder. I have no idea why, but it's worth a try.

Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();

Well, if you like the developer way, Visual Studio Code allows you to specify the different file types for the tabSize. Here is the example of my settings.json with default four spaces and JavaScript/JSON two spaces:

{
  // I want my default to be 4, but JavaScript/JSON to be 2
  "editor.tabSize": 4,
  "[javascript]": {
    "editor.tabSize": 2
  },
  "[json]": {
    "editor.tabSize": 2
  },

  // This one forces the tab to be **space**
  "editor.insertSpaces": true
}

PS: Well, if you do not know how to open this file (specially in a new version of Visual Studio Code), you can:

1. Left-bottom gear →
2. Settings → top right Open Settings

If you put the properties file in the same package as class Foo, you can easily load it with

new Properties().load(Foo.class.getResourceAsStream("file.properties"))

Given that Properties extends Hashtable you can iterate over the values in the same manner as you would in a Hashtable.

If you use the *.properties extension you can get editor support, e.g. Eclipse has a properties file editor.

In a few words:

• 200 when an object is created and returned
• 201 when an object is created but only its reference is returned (such as an ID or a link)

Alternatively you can also,

1) Navigate to that method by Ctrl+Click on the method. The new tab/window will opened with text "Source not found" and button "Attach Source.." in it
2) Click the button "Attach Source.."
3) New window pops up. Click the button "External Folder"
4) Locate the JavaFX javadoc folder. If you are on Windows with default installation settings, then the folder path is C:\Program Files\Oracle\JavaFX 2.0 SDK\docs

var _href = $("a.directions-link").attr("href");
$("a.directions-link").attr("href", _href + '&saddr=50.1234567,-50.03452');

To loop with each()

$("a.directions-link").each(function() {
   var $this = $(this);       
   var _href = $this.attr("href"); 
   $this.attr("href", _href + '&saddr=50.1234567,-50.03452');
});

There's a python module especially made for reading and writing to and from binary encoded data called 'struct'. Since versions of Python under 2.6 doesn't support str.format, a custom method needs to be used to create binary formatted strings.

import struct

# binary string
def bstr(n): # n in range 0-255
    return ''.join([str(n >> x & 1) for x in (7,6,5,4,3,2,1,0)])

# read file into an array of binary formatted strings.
def read_binary(path):
    f = open(path,'rb')
    binlist = []
    while True:
        bin = struct.unpack('B',f.read(1))[0] # B stands for unsigned char (8 bits)
        if not bin:
            break
        strBin = bstr(bin)
        binlist.append(strBin)
    return binlist

Your syntax is pretty screwy.

Change this:

input:not(disabled)not:[type="submit"]:focus{

to:

input:not(:disabled):not([type="submit"]):focus{

Seems that many people don't realize :enabled and :disabled are valid CSS selectors...

I have encountered the exception java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/7505 in getting the doucument from the downloads. This solution worked for me.

else if (isDownloadsDocument(uri)) {
            String fileName = getFilePath(context, uri);
            if (fileName != null) {
                return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName;
            }

            String id = DocumentsContract.getDocumentId(uri);
            if (id.startsWith("raw:")) {
                id = id.replaceFirst("raw:", "");
                File file = new File(id);
                if (file.exists())
                    return id;
            }

            final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
            return getDataColumn(context, contentUri, null, null);
        }

This the method used to get the filepath

   public static String getFilePath(Context context, Uri uri) {

    Cursor cursor = null;
    final String[] projection = {
            MediaStore.MediaColumns.DISPLAY_NAME
    };

    try {
        cursor = context.getContentResolver().query(uri, projection, null, null,
                null);
        if (cursor != null && cursor.moveToFirst()) {
            final int index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DISPLAY_NAME);
            return cursor.getString(index);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}

$('.toggle img').data('block', 'something').attr('src', 'something.jpg');

If you would like to combine the matrix with some visualisations I can recommend (I am using the built in iris dataset):

library(psych)
pairs.panels(iris[1:4])  # select columns 1-4

The Performance Analytics basically does the same but includes significance indicators by default.

library(PerformanceAnalytics)
chart.Correlation(iris[1:4])

Or this nice and simple visualisation:

library(corrplot)
x <- cor(iris[1:4])
corrplot(x, type="upper", order="hclust")

To pass a NULL to MySQL, you do just that.

INSERT INTO table (field,field2) VALUES (NULL,3)

So, in your code, check if $intLat, $intLng are empty, if they are, use NULL instead of '$intLat' or '$intLng'.

$intLat = !empty($intLat) ? "'$intLat'" : "NULL";
$intLng = !empty($intLng) ? "'$intLng'" : "NULL";

$query = "INSERT INTO data (notes, id, filesUploaded, lat, lng, intLat, intLng)
          VALUES ('$notes', '$id', TRIM('$imageUploaded'), '$lat', '$long', 
                  $intLat, $intLng)";

OK, this is a bad thing to be doing. Don't mock a list; instead, mock the individual objects inside the list. See Mockito: mocking an arraylist that will be looped in a for loop for how to do this.

Also, why are you using PowerMock? You don't seem to be doing anything that requires PowerMock.

But the real cause of your problem is that you are using when on two different objects, before you complete the stubbing. When you call when, and provide the method call that you are trying to stub, then the very next thing you do in either Mockito OR PowerMock is to specify what happens when that method is called - that is, to do the thenReturn part. Each call to when must be followed by one and only one call to thenReturn, before you do any more calls to when. You made two calls to when without calling thenReturn - that's your error.

We're in the process of moving all the databases to source control. We're using sqlcompare to script out the database (a profession edition feature, unfortunately) and putting that result into SVN.

The success of your implementation will depend a lot on the culture and practices of your organization. People here believe in creating a database per application. There is a common set of databases that are used by most applications as well causing a lot of interdatabase dependencies (some of them are circular). Putting the database schemas into source control has been notoriously difficult because of the interdatabase dependencies that our systems have.

Best of luck to you, the sooner you try it out the sooner you'll have your issues sorted out.

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

Console.WriteLine(string.Join<TYPE>("\n", someObjectList));

I found it much easier to debut by printing out where each row meets the condition:

for n in df.columns:
    if(np.where(df[n] == 103)):
        print(n)
        print(df[df[n] == 103].index)

1. Anonymous functions are functions that are dynamically declared at runtime. They’re called anonymous functions because they aren’t given a name in the same way as normal functions.

   Anonymous functions are declared using the function operator instead of the function declaration. You can use the function operator to create a new function wherever it’s valid to put an expression. For example you could declare a new function as a parameter to a function call or to assign a property of another object.

   Here’s a typical example of a named function:

   function flyToTheMoon() { alert("Zoom! Zoom! Zoom!"); } flyToTheMoon(); Here’s the same example created as an anonymous function:

   var flyToTheMoon = function() { alert("Zoom! Zoom! Zoom!"); } flyToTheMoon();

   For details please read here:

Have you checked the docstring of write()? It says:

write(str) -> None. Write string str to file.

Note that due to buffering, flush() or close() may be needed before the file on disk reflects the data written.

So you need to convert y to str first.

Also note that the string will be written at the current position which will be at the end of the file, because you'll already have read the old value. Use f.seek(0) to get to the beginning of the file.`

Edit: As for the IOError, this issue seems related. A cite from there:

For the modes where both read and writing (or appending) are allowed (those which include a "+" sign), the stream should be flushed (fflush) or repositioned (fseek, fsetpos, rewind) between either a reading operation followed by a writing operation or a writing operation followed by a reading operation.

So, I suggest you try f.seek(0) and maybe the problem goes away.

Use ls or find to have all the files that were created today.

Using ls : ls -ltr | grep "$(date '+%b %e')"

Using find : cd $YOUR_DIRECTORY; find . -ls 2>/dev/null| grep "$(date '+%b %e')"

Two more reasons not to use inline handlers:

They can require tedious quote escaping issues

Given an arbitrary string, if you want to be able to construct an inline handler that calls a function with that string, for the general solution, you'll have to escape the attribute delimiters (with the associated HTML entity), and you'll have to escape the delimiter used for the string inside the attribute, like the following:

const str = prompt('What string to display on click?', 'foo\'"bar');
const escapedStr = str
  // since the attribute value is going to be using " delimiters,
  // replace "s with their corresponding HTML entity:
  .replace(/"/g, '"')
  // since the string literal inside the attribute is going to delimited with 's,
  // escape 's:
  .replace(/'/g, "\\'");
  
document.body.insertAdjacentHTML(
  'beforeend',
  '<button onclick="alert(\'' + escapedStr + '\')">click</button>'
);

That's incredibly ugly. From the above example, if you didn't replace the 's, a SyntaxError would result, because alert('foo'"bar') is not valid syntax. If you didn't replace the "s, then the browser would interpret it as an end to the onclick attribute (delimited with "s above), which would also be incorrect.

If one habitually uses inline handlers, one would have to make sure to remember do something similar to the above (and do it right) every time, which is tedious and hard to understand at a glance. Better to avoid inline handlers entirely so that the arbitrary string can be used in a simple closure:

const str = prompt('What string to display on click?', 'foo\'"bar');
const button = document.body.appendChild(document.createElement('button'));
button.textContent = 'click';
button.onclick = () => alert(str);

Isn't that so much nicer?

The scope chain of an inline handler is extremely peculiar

What do you think the following code will log?

let disabled = true;

<form>
  <button onclick="console.log(disabled);">click</button>
</form>

Try it, run the snippet. It's probably not what you were expecting. Why does it produce what it does? Because inline handlers run inside with blocks. The above code is inside three with blocks: one for the document, one for the <form>, and one for the <button>:

let disabled = true;

<form>
  <button onclick="console.log(disabled);">click</button>
</form>

Since disabled is a property of the button, referencing disabled inside the inline handler refers to the button's property, not the outer disabled variable. This is quite counter-intuitive. with has many problems: it can be the source of confusing bugs and significantly slows down code. It isn't even permitted at all in strict mode. But with inline handlers, you're forced to run the code through withs - and not just through one with, but through multiple nested withs. It's crazy.

with should never be used in code. Because inline handlers implicitly require with along with all its confusing behavior, inline handlers should be avoided as well.

If you have only two or three condition(sizes) then you can use @Overide onMeasure like

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) 
{
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

And change your size for these conditions in CustomView class easily.

You can use SUBSTRING and CONVERT:

SELECT stuff
FROM table
WHERE conditions
ORDER BY CONVERT(SUBSTRING(name_column, 6), SIGNED INTEGER);

Where name_column is the column with the "name-" values. The SUBSTRING removes everything up before the sixth character (i.e. the "name-" prefix) and then the CONVERT converts the left over to a real integer.

UPDATE: Given the changing circumstances in the comments (i.e. the prefix can be anything), you'll have to throw a LOCATE in the mix:

ORDER BY CONVERT(SUBSTRING(name_column, LOCATE('-', name_column) + 1), SIGNED INTEGER);

This of course assumes that the non-numeric prefix doesn't have any hyphens in it but the relevant comment says that:

name can be any sequence of letters

so that should be a safe assumption.

return Labels; should do the trick!

public static ArtworkData[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels;
}

You can create an alias in .bashrc file as follows

alias vg='valgrind --leak-check=full -v --track-origins=yes --log-file=vg_logfile.out'

So whenever you want to check memory leaks, just do simply

vg ./<name of your executable> <command line parameters to your executable>

This will generate a Valgrind log file in the current directory.

I'm using Netbeans, i solved my problem by putting the file in: Other Sources default package, then i called it in this way:

ApplicationContext context =new ClassPathXmlApplicationContext("bean.xml");

resources folder

you can bind to multiple events by separating them with a space:

$(":input").on("keyup change", function(e) {
    // do stuff!
})

docs here.

hope that helps. cheers!

You need to create new TextNodes as well as td nodes for each column, not reuse them among all of the columns as your code is doing.

Edit: Revise your code like so:

for (var i = 1; i < 4; i++)
{
   tr[i] = document.createElement('tr');   
      var td1 = document.createElement('td');
      var td2 = document.createElement('td');
      td1.appendChild(document.createTextNode('Text1'));
      td2.appendChild(document.createTextNode('Text2'));
      tr[i].appendChild(td1);
      tr[i].appendChild(td2);
  table.appendChild(tr[i]);
}

You can directly return a different view like:

return View("NameOfView", Model);

Or you can make a partial view and can return like:

return PartialView("PartialViewName", Model);

SELECT
  category,
  COUNT(*) AS `num`
FROM
  posts
GROUP BY
  category

For anyone else who is having this issue, I didn't see my resolution in any of these answers.

After having a .pbxproj merge conflict which was manually addressed (albeit poorly), there were duplicate references to individual class files in the .pbxproj. Deleting those from the Project > Build Phases > Compile Sources fixed everything for me.

Hope this helps someone down the line.

If you have to use the:

myLabel.numberOfLines = 0;

property you can also use a standard line break ("\n"), in code, to force a new line.

   self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

I was inspired by Thejuan's answer to write a simpler attached property. No styles, no triggers; instead, you can just do this:

<Window ...
        xmlns:xc="clr-namespace:ExCastle.Wpf"
        xc:DialogCloser.DialogResult="{Binding DialogResult}">

This is almost as clean as if the WPF team had gotten it right and made DialogResult a dependency property in the first place. Just put a bool? DialogResult property on your ViewModel and implement INotifyPropertyChanged, and voilà, your ViewModel can close the Window (and set its DialogResult) just by setting a property. MVVM as it should be.

Here's the code for DialogCloser:

using System.Windows;

namespace ExCastle.Wpf
{
    public static class DialogCloser
    {
        public static readonly DependencyProperty DialogResultProperty =
            DependencyProperty.RegisterAttached(
                "DialogResult",
                typeof(bool?),
                typeof(DialogCloser),
                new PropertyMetadata(DialogResultChanged));

        private static void DialogResultChanged(
            DependencyObject d,
            DependencyPropertyChangedEventArgs e)
        {
            var window = d as Window;
            if (window != null)
                window.DialogResult = e.NewValue as bool?;
        }
        public static void SetDialogResult(Window target, bool? value)
        {
            target.SetValue(DialogResultProperty, value);
        }
    }
}

Wrote a tutorial so that you can animate your activity's in and out,

As per https://stackoverflow.com/a/33859341/446250, having internet connection sharing enabled for my ethernet adapter ended up causing this problem for me. Disabling the sharing fixed the problem

Adding to @Josh's example;

fName = [FILE TO OPEN]
if os.path.exists(fName):
    with open(fName, 'rb') as f:
        #add you code to handle the file contents here.
elif IOError:
    print "Unable to open file: "+str(fName)

This way you can attempt to open the file, but if it doesn't exist (if it raises an IOError), alert the user!

You can use chmod with the X mode letter (the capital X) to set the executable flag only for directories.

In the example below the executable flag is cleared and then set for all directories recursively:

~$ mkdir foo
~$ mkdir foo/bar
~$ mkdir foo/baz
~$ touch foo/x
~$ touch foo/y

~$ chmod -R go-X foo 
~$ ls -l foo
total 8
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 bar
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

~$ chmod -R go+X foo 
~$ ls -l foo
total 8
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 bar
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 baz

A bit of explaination:

• chmod -x foo - clear the eXecutable flag for foo
• chmod +x foo - set the eXecutable flag for foo
• chmod go+x foo - same as above, but set the flag only for Group and Other users, don't touch the User (owner) permission
• chmod go+X foo - same as above, but apply only to directories, don't touch files
• chmod -R go+X foo - same as above, but do this Recursively for all subdirectories of foo

Coded to 2010 specs (ya, it is 2016 with ES6 generators). Here's my take, with options to emulate the Python's range() function.

Array.range = function(start, end, step){
    if (start == undefined) { return [] } // "undefined" check

    if ( (step === 0) )  {  return []; // vs. throw TypeError("Invalid 'step' input")
    }  // "step" == 0  check

    if (typeof start == 'number') { // number check
        if (typeof end == 'undefined') { // single argument input
            end = start;
            start = 0;
            step = 1;
        }
        if ((!step) || (typeof step != 'number')) {
          step = end < start ? -1 : 1;
        }

        var length = Math.max(Math.ceil((end - start) / step), 0);
        var out = Array(length);

        for (var idx = 0; idx < length; idx++, start += step) {
          out[idx] = start;
        }

        // Uncomment to check "end" in range() output, non pythonic
        if ( (out[out.length-1] + step) == end ) { // "end" check
            out.push(end)
        }

    } else { 
        // Historical: '&' is the 27th letter: http://nowiknow.com/and-the-27th-letter-of-the-alphabet/
        // Axiom: 'a' < 'z' and 'z' < 'A'
        // note: 'a' > 'A' == true ("small a > big A", try explaining it to a kid! )

        var st = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ&'; // axiom ordering

        if (typeof end == 'undefined') { // single argument input
            end = start;
            start = 'a';
        }

        var first = st.indexOf(start);
        var last = st.indexOf(end);

        if ((!step) || (typeof step != 'number')) {
          step = last < first ? -1 : 1;
        }

        if ((first == -1) || (last == -1 )) { // check 'first' & 'last'
            return []
        }

        var length = Math.max(Math.ceil((last - first) / step), 0);
        var out = Array(length);

        for (var idx = 0; idx < length; idx++, first += step) {
          out[idx] = st[first];
        } 

        // Uncomment to check "end" in range() output, non pythonic
        if ( (st.indexOf(out[out.length-1]) + step ) == last ) { // "end" check
            out.push(end)
        }
    }
    return out;
}

Example:

Array.range(5);       // [0,1,2,3,4,5]
Array.range(4,-4,-2); // [4, 2, 0, -2, -4]
Array.range('a','d'); // ["a", "b", "c", "d"]
Array.range('B','y'); // ["B", "A", "z", "y"], different from chr() ordering
Array.range('f');     // ["a", "b", "c", "d", "e", "f"]
Array.range(-5);      // [], similar to python
Array.range(-5,0)     // [-5,-4-,-3-,-2,-1,0]

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

This may have changed since the question was asked, but there is a difference between stopping an instance and terminating an instance.

If your instance is EBS-based, it can be stopped. It will remain in your account, but you will not be charged for it (you will continue to be charged for EBS storage associated with the instance and unused Elastic IP addresses). You can re-start the instance at any time.

If the instance is terminated, it will be deleted from your account. You’ll be charged for any remaining EBS volumes, but by default the associated EBS volume will be deleted. This can be configured when you create the instance using the command-line EC2 API Tools.

You can put this code in cshtml if you are returning view from controller and you want to increase the length of view bag data while encoding in json in cshtml

@{
    var jss = new System.Web.Script.Serialization.JavaScriptSerializer();
    jss.MaxJsonLength = Int32.MaxValue;
    var userInfoJson = jss.Serialize(ViewBag.ActionObj);
}

var dataJsonOnActionGrid1 = @Html.Raw(userInfoJson);

Now, dataJsonOnActionGrid1 will be accesible on js page and you will get proper result.

Thanks

I looked all the ones above. Ended up writing myself. You do not need momentjs for this. A native for loop is enough and makes most sense because a for loop exists to count values in a range.

One Liner:

var getDaysArray = function(s,e) {for(var a=[],d=new Date(s);d<=e;d.setDate(d.getDate()+1)){ a.push(new Date(d));}return a;};

Long Version

var getDaysArray = function(start, end) {
    for(var arr=[],dt=new Date(start); dt<=end; dt.setDate(dt.getDate()+1)){
        arr.push(new Date(dt));
    }
    return arr;
};

List dates in between:

var daylist = getDaysArray(new Date("2018-05-01"),new Date("2018-07-01"));
daylist.map((v)=>v.toISOString().slice(0,10)).join("")
/*
Output: 
    "2018-05-01
    2018-05-02
    2018-05-03
    ...
    2018-06-30
    2018-07-01"
*/

Days from a past date until now:

var daylist = getDaysArray(new Date("2018-05-01"),new Date());
daylist.map((v)=>v.toISOString().slice(0,10)).join("")

Note that COLUMNS is:

1. NOT an environment variable. It is an ordinary bash parameter that is set by bash itself.
2. Set automatically upon receipt of a SIGWINCH signal.

That second point usually means that your COLUMNS variable will only be set in your interactive shell, not in a bash script.

If your script's stdin is connected to your terminal you can manually look up the width of your terminal by asking your terminal:

tput cols

And to use this in your SVN command:

svn diff "$@" --diff-cmd /usr/bin/diff -x "-y -w -p -W $(tput cols)"

(Note: you should quote "$@" and stay away from eval ;-))

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

Using ggplot and a little dplyr for data manipulation:

set.seed(42)
df <- data.frame(x = rep(1:10,each=5), y = rnorm(50))

library(ggplot2)
library(dplyr)

df.summary <- df %>% group_by(x) %>%
    summarize(ymin = min(y),
              ymax = max(y),
              ymean = mean(y))

ggplot(df.summary, aes(x = x, y = ymean)) +
    geom_point(size = 2) +
    geom_errorbar(aes(ymin = ymin, ymax = ymax))

If there's an additional grouping column (OP's example plot has two errorbars per x value, saying the data is sourced from two files), then you should get all the data in one data frame at the start, add the grouping variable to the dplyr::group_by call (e.g., group_by(x, file) if file is the name of the column) and add it as a "group" aesthetic in the ggplot, e.g., aes(x = x, y = ymean, group = file).

I second opinions that you should choose the iteration method according to your need. I would suggest you actually not to ever loop through native Array with for in structure. It is way slower and, as Chase Seibert pointed at the moment ago, not compatible with Prototype framework.

There is an excellent benchmark on different looping styles that you absolutely should take a look at if you work with JavaScript. Do not do early optimizations, but you should keep that stuff somewhere in the back of your head.

I would use for in to get all properties of an object, which is especially useful when debugging your scripts. For example, I like to have this line handy when I explore unfamiliar object:

l = ''; for (m in obj) { l += m + ' => ' + obj[m] + '\n' } console.log(l);

It dumps content of the whole object (together with method bodies) to my Firebug log. Very handy.

let obj = MyObject();

elem.someEvent( function(){ obj.func(param) } );

//calls the MyObject.func, passing the param.

If you have sklearn isntalled, a simple alternative is to use sklearn.metrics.auc

This computes the area under the curve using the trapezoidal rule given arbitrary x, and y array

import numpy as np
from sklearn.metrics import auc

dx = 5
xx = np.arange(1,100,dx)
yy = np.arange(1,100,dx)

print('computed AUC using sklearn.metrics.auc: {}'.format(auc(xx,yy)))
print('computed AUC using np.trapz: {}'.format(np.trapz(yy, dx = dx)))

both output the same area: 4607.5

the advantage of sklearn.metrics.auc is that it can accept arbitrarily-spaced 'x' array, just make sure it is ascending otherwise the results will be incorrect

If you want to pass an app-instance to others in Node-Typescript :

Option 1: With the help of import (when importing)

//routes.ts
import { Application } from "express";
import { categoryRoute } from './routes/admin/category.route'
import { courseRoute } from './routes/admin/course.route';

const routing = (app: Application) => {
    app.use('/api/admin/category', categoryRoute)
    app.use('/api/admin/course', courseRoute)
}
export { routing }

Then import it and pass app:

import express, { Application } from 'express';

const app: Application = express();
import('./routes').then(m => m.routing(app))

Option 2: With the help of class

// index.ts
import express, { Application } from 'express';
import { Routes } from './routes';


const app: Application = express();
const rotues = new Routes(app)
...

Here we will access the app in the constructor of Routes Class

// routes.ts
import { Application } from 'express'
import { categoryRoute } from '../routes/admin/category.route'
import { courseRoute } from '../routes/admin/course.route';

class Routes {
    constructor(private app: Application) {
        this.apply();
    }

    private apply(): void {
       this.app.use('/api/admin/category', categoryRoute)
       this.app.use('/api/admin/course', courseRoute)
    }
}

export { Routes }

ClassList add

var dynamic=document.getElementById("dynamic");
dynamic.classList.add("red");
dynamic.classList.add("size");
dynamic.classList.add("bold");

.red{
color:red;
}
.size{
font-size:40px;
}
.bold{
font-weight:800;
}

<div id="dynamic">dynamic css</div>

I resolved this issue by right clicking on the folder containing the files and choosing Exclude From Project and then right clicking again and selecting Include In Project (you first have to enable Show All Files to make the excluded folder visible)

Unfortunately, AFAIK you cannot run multiple SQL statements under one named query in Access in the traditional sense.

You can make several queries, then string them together with VBA (DoCmd.OpenQuery if memory serves).

You can also string a bunch of things together with UNION if you wish.

While loading csv file contain date column.We have two approach to to make pandas to recognize date column i.e

1. Pandas explicit recognize the format by arg date_parser=mydateparser

2. Pandas implicit recognize the format by agr infer_datetime_format=True

Some of the date column data

01/01/18

01/02/18

Here we don't know the first two things It may be month or day. So in this case we have to use Method 1:- Explicit pass the format

    mydateparser = lambda x: pd.datetime.strptime(x, "%m/%d/%y")
    df = pd.read_csv(file_name, parse_dates=['date_col_name'],
date_parser=mydateparser)

Method 2:- Implicit or Automatically recognize the format

df = pd.read_csv(file_name, parse_dates=[date_col_name],infer_datetime_format=True)

While the existing answers have given solutions to solve the issue and the second half of the question, they do not provide an answer to the self discovery aspect of the first half of the question that is in bold:

"How can I see which variable causes memory overhead...?"

It may not have been as robust 3 years ago, but the Chrome Developer Tools "Profiles" section is now quite powerful and feature rich. The Chrome team has an insightful article on using it and thus also how garbage collection (GC) works in javascript, which is at the core of this question.

Since delete is basically the root of the currently accepted answer by Yochai Akoka, it's important to remember what delete does. It's irrelevant if not combined with the concepts of how GC works in the next two answers: if there's an existing reference to an object it's not cleaned up. The answers are more correct, but probably not as appreciated because they require more thought than just writing 'delete'. Yes, one possible solution may be to use delete, but it won't matter if there's another reference to the memory leak.

Another answer appropriately mentions circular references and the Chrome team documentation can provide much more clarity as well as the tools to verify the cause.

Since delete was mentioned here, it also may be useful to provide the resource Understanding Delete. Although it does not get into any of the actual solution which is really related to javascript's garbage collector.

If you want to right-align in a form, you can try:

| Option | Description |
| ------:| -----------:|
| data   | path to data files to supply the data that will be passed into templates. |
| engine | engine to be used for processing templates. Handlebars is the default. |
| ext    | extension to be used for dest files. |

https://learn.getgrav.org/content/markdown#right-aligned-text

Or try this ;)

try {
  this.setContentPane(
    new JLabel(new ImageIcon(ImageIO.read(new File("your_file.jpeg")))));
} catch (IOException e) {};

You are correct - here is a fully working example - you'll see that var result is implicitly a string because the return type is specified on the greet() function. Change the type to number and you'll get warnings.

class Greeter {
    greeting: string;
    constructor (message: string) {
        this.greeting = message;
    }
    greet() : string {
        return "Hello, " + this.greeting;
    }
} 

var greeter = new Greeter("Hi");
var result = greeter.greet();

Here is the number example - you'll see red squiggles in the playground editor if you try this:

greet() : number {
    return "Hello, " + this.greeting;
}

You can use react-pure-lifecycle to add lifecycle functions to functional components.

Example:

import React, { Component } from 'react';
import lifecycle from 'react-pure-lifecycle';

const methods = {
  componentDidMount(props) {
    console.log('I mounted! Here are my props: ', props);
  }
};

const Channels = props => (
<h1>Hello</h1>
)

export default lifecycle(methods)(Channels);

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

Bootstrap 4 (4.0.0-alpha.2) uses the css property column-count in the card-columns class to define how many columns of cards would be displayed inside the div element.
But this property has only two values:

• The default value 1 for small screens (max-width: 34em)
• The value 3 for all other sizes (min-width: 34em)

Here's how it is implemented in bootstrap.min.css :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count:3;
        -moz-column-count:3;
        column-count:3;
        ?
    }
    ?
}

To make the card stacking responsive, you can add the following media queries to your css file and modify the values for min-width as per your requirements :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count: 2;
        -moz-column-count: 2;
        column-count: 2;
    }
}

@media (min-width: 48em) {
    .card-columns {
        -webkit-column-count: 3;
        -moz-column-count: 3;
        column-count: 3;
    }
}

@media (min-width: 62em) {
    .card-columns {
        -webkit-column-count: 4;
        -moz-column-count: 4;
        column-count: 4;
    }
}

@media (min-width: 75em) {
    .card-columns {
        -webkit-column-count: 5;
        -moz-column-count: 5;
        column-count: 5;
    }
}

tags.map(&:name)

is The same as

tags.map{|tag| tag.name}

&:name just uses the symbol as the method name to be called.

Probably the easiest way to explore your ElasticSearch cluster is to use elasticsearch-head.

You can install it by doing:

cd elasticsearch/
./bin/plugin -install mobz/elasticsearch-head

Then (assuming ElasticSearch is already running on your local machine), open a browser window to:

http://localhost:9200/_plugin/head/

Alternatively, you can just use curl from the command line, eg:

Check the mapping for an index:

curl -XGET 'http://127.0.0.1:9200/my_index/_mapping?pretty=1' 

Get some sample docs:

curl -XGET 'http://127.0.0.1:9200/my_index/_search?pretty=1' 

See the actual terms stored in a particular field (ie how that field has been analyzed):

curl -XGET 'http://127.0.0.1:9200/my_index/_search?pretty=1'  -d '
 {
    "facets" : {
       "my_terms" : {
          "terms" : {
             "size" : 50,
             "field" : "foo"
          }
       }
    }
 }

UPDATE : Sense plugin in Marvel

By far the easiest way of writing curl-style commands for Elasticsearch is the Sense plugin in Marvel.

It comes with source highlighting, pretty indenting and autocomplete.

Note: Sense was originally a standalone chrome plugin but is now part of the Marvel project.

Do not use the * selector as that will apply to all elements on the page. Suppose you have a structure like this:

...
<body>
    <div id="content">
        <b>This is the main container.</b>
    </div>
</body>
</html>

You can then center the #content div using:

#content {
    width: 400px;
    margin: 0 auto;
    background-color: #66ffff;
}

Don't know what you've seen elsewhere but this is the way to go. The * { margin: 0; padding: 0; } snippet you've seen is for resetting browser's default definitions for all browsers to make your site behave similarly on all browsers, this has nothing to do with centering the main container.

Most browsers apply a default margin and padding to some elements which usually isn't consistent with other browsers' implementations. This is why it is often considered smart to use this kind of 'resetting'. The reset snippet you presented is the most simplest of reset stylesheets, you can read more about the subject here:

• http://meyerweb.com/eric/tools/css/reset/

It would return NULL but if taken as BIGINT would show the number

I'm assuming you figured this out already but:

Technical Reference for Log Files in Configuration Manager

That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs

AppEnforce.log will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)

This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.

This code sample can be used to change date format. Here I want to change from yyyy-MM-dd to dd-MM-yyyy. Here pos is position of column.

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.CellStyle;
import org.apache.poi.ss.usermodel.CreationHelper;

import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

class Test{ 
public static void main( String[] args )
{
String input="D:\\somefolder\\somefile.xlsx";
String output="D:\\somefolder\\someoutfile.xlsx"
FileInputStream file = new FileInputStream(new File(input));
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet sheet = workbook.getSheetAt(0);
Iterator<Row> iterator = sheet.iterator();
Cell cell = null;
Row row=null;
row=iterator.next();
int pos=5; // 5th column is date.
while(iterator.hasNext())
{
    row=iterator.next();

    cell=row.getCell(pos-1);
    //CellStyle cellStyle = wb.createCellStyle();
    XSSFCellStyle cellStyle = (XSSFCellStyle)cell.getCellStyle();
    CreationHelper createHelper = wb.getCreationHelper();
    cellStyle.setDataFormat(
        createHelper.createDataFormat().getFormat("dd-MM-yyyy"));
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    Date d=null;
    try {
        d= sdf.parse(cell.getStringCellValue());
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        d=null;
        e.printStackTrace();
        continue;
    }
    cell.setCellValue(d);
    cell.setCellStyle(cellStyle);
   }

file.close();
FileOutputStream outFile =new FileOutputStream(new File(output));
workbook.write(outFile);
workbook.close();
outFile.close();
}}

You can also use inspect.getdoc. It cleans up the __doc__ by normalizing tabs to spaces and left shifting the doc body to remove common leading spaces.

There's another CURL method if you are going that way.

This is pretty straightforward once you get your head around the way the PHP curl extension works, combining various flags with setopt() calls. In this example I've got a variable $xml which holds the XML I have prepared to send - I'm going to post the contents of that to example's test method.

$url = 'http://api.example.com/services/xmlrpc/';
$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);
//process $response

First we initialised the connection, then we set some options using setopt(). These tell PHP that we are making a post request, and that we are sending some data with it, supplying the data. The CURLOPT_RETURNTRANSFER flag tells curl to give us the output as the return value of curl_exec rather than outputting it. Then we make the call and close the connection - the result is in $response.

Actually, you can write your StyleSheet.create object as a key with function value, it works properly but it has a type issue in TypeScript:

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

const SomeComponent = ({ bgColor }) => (
  <View style={styles.wrapper(bgColor)}>
    <Text style={styles.text}>3333</Text>
  </View>
);

const styles = StyleSheet.create({
  wrapper: color => ({
    flex: 1,
    backgroundColor: color,
  }),
  text: {
    color: 'red',
  },

In Tomcat a .java and .class file will be created for every jsp files with in the application and the same can be found from the path below, Apache-Tomcat\work\Catalina\localhost\'ApplicationName'\org\apache\jsp\index_jsp.java

In your case the jsp name is error.jsp so the path should be something like below Apache-Tomcat\work\Catalina\localhost\'ApplicationName'\org\apache\jsp\error_jsp.java in line no 124 you are trying to access a null object which results in null pointer exception.

Try this if you wan't to use SSL certificates:

import subprocess

try:
    # Set scp and ssh data.
    connUser = 'john'
    connHost = 'my.host.com'
    connPath = '/home/john/'
    connPrivateKey = '/home/user/myKey.pem'

    # Use scp to send file from local to host.
    scp = subprocess.Popen(['scp', '-i', connPrivateKey, 'myFile.txt', '{}@{}:{}'.format(connUser, connHost, connPath)])

except CalledProcessError:
    print('ERROR: Connection to host failed!')

OP asked about running from node not from mocha. This is a very common use case, see Using Mocha Programatically

This is what injected describe and it into my tests.

mocha.ui('bdd').run(function (failures) {
    process.on('exit', function () {
      process.exit(failures);
    });
  });

I tried tdd like in the docs, but that didn't work, bdd worked though.

$ ionic info Ionic:

Ionic CLI : 5.4.16

Utility:

cordova-res : not installed native-run : 0.3.0

System:

NodeJS : v12.16.1 npm : 6.13.4 OS : Linux 5.3

I've tried all of these solutions excluding the COBOL answer... lol

None of these solutions were good enough. I needed randoms in a fast for int loop and I was getting tons of duplicate values even in very wide ranges. After settling for kind of random results far too long I decided to finally tackle this problem once and for all.

It's all about the seed.

I create a random integer by parsing out the non-digits from Guid, then I use that to instantiate my Random class.

public int GenerateRandom(int min, int max)
{
    var seed = Convert.ToInt32(Regex.Match(Guid.NewGuid().ToString(), @"\d+").Value);
    return new Random(seed).Next(min, max);
}

Update: Seeding isn't necessary if you instantiate the Random class once. So it'd be best to create a static class and call a method off that.

public static class IntUtil
{
   private static Random random;

   private static void Init()
   {
      if (random == null) random = new Random();
   }

   public static int Random(int min, int max)
   {
      Init();
      return random.Next(min, max);
   }
}

Then you can use the static class like so..

for(var i = 0; i < 1000; i++)
{
   int randomNumber = IntUtil.Random(1,100);
   Console.WriteLine(randomNumber); 
}

I admit I like this approach better.

The regular expression:

^[^_]*_(.*)$

Then get the part between parenthesis. In perl:

my var = "3.04_somename.jpg";
$var =~ m/^[^_]*_(.*)$/;
my fileName = $1;

In Java:

String var = "3.04_somename.jpg";
String fileName = "";
Pattern pattern = Pattern.compile("^[^_]*_(.*)$");
Matcher matcher = pattern.matcher(var);
if (matcher.matches()) {
    fileName = matcher.group(1);
}

...

I have encountered this problem when upgrading a VS2010 WCF+Silverlight solution in VS2015 Professional. Besides automatically upgrading from Silverlight 4 to Silverlight 5, the service reference reuse checkbox value was changed and generation failed.

OK, my answer is super nice:

Just put your Images in Public Directory (public/...folder or direct images).
Public directory is by default rendered by laravel application.
Let's suppose I stored images in public/images/myimage.jpg.
Then in your HTML view, page like: (image.blade.php)

<img src="{{url('/images/myimage.jpg')}}" alt="Image"/>

           // Left shift divisor until it's smaller than dividend
            if (r < Integer.MAX_VALUE && r >= 0) { // Avoid cases where comparison between long and int doesn't make sense
                if (r <= dividend) { 
                    quotient |= (1 << i);

Please try it:

see this bin: http://jsbin.com/yacom/2/edit

should set parent element to

display:table-cell;
vertical-align:middle;
text-align:center;

Also you can setup extJs writer with encode: true and it will send data regularly (and, hence, you will be able to retrieve data via $_POST and $_GET).

... the values will be sent as part of the request parameters as opposed to a raw post (via docs for encode config of Ext.data.writer.Json)

UPDATE

Also docs say that:

The encode option should only be set to true when a root is defined

So, probably, writer's root config is required.

APIs are messy because they keep changing. This pure javascript way worked for me:

 <div id="divScope" class="boom-lightbox" style="display: none;">
    <iframe id="ytplayer" width="720" height="405"   src="https://www.youtube.com/embed/M7lc1UVf-VE" frameborder="0" allowfullscreen>    </iframe>
  </div>  

//if I want i can set scope to a specific region
var myScope = document.getElementById('divScope');      
//otherwise set scope as the entire document
//var myScope = document;

//if there is an iframe inside maybe embedded multimedia video/audio, we should reload so it stops playing
var iframes = myScope.getElementsByTagName("iframe");
if (iframes != null) {
    for (var i = 0; i < iframes.length; i++) {
        iframes[i].src = iframes[i].src; //causes a reload so it stops playing, music, video, etc.
    }
}

There is no log file. Each node.js "app" is a separate entity. By default it will log errors to STDERR and output to STDOUT. You can change that when you run it from your shell to log to a file instead.

node my_app.js > my_app_log.log 2> my_app_err.log

Alternatively (recommended), you can add logging inside your application either manually or with one of the many log libraries:

• winston
• log4js
• ...

Generally, this is how you open an OS folder containing a bunch of vdmk files on VMware Player.

You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

VAR x REFCURSOR;
EXEC GetGrantListByPI(args, :x);
PRINT x;

Okay, I've figured this out. Postgresql does not detect changes to the folder /var/lib/postgresql once it's launched, at least not the kind of changes I want it do detect.

The first solution is to start a container with bash instead of starting the postgres server directly, restore the data, and then start the server manually.

The second solution is to use a data container. I didn't get the point of it before, now I do. This data container allows to restore the data before starting the postgres container. Thus, when the postgres server starts, the data are already there.

jQuery has removed $.browser from 1.9 and their latest release.

But you can still use $.browser as a standalone plugin, found here

According to @mythz answer, I decide to post updated version of his extension using swift3 syntax.

extension Date {
    static func from(_ year: Int, _ month: Int, _ day: Int) -> Date?
    {
        let gregorianCalendar = Calendar(identifier: .gregorian)
        let dateComponents = DateComponents(calendar: gregorianCalendar, year: year, month: month, day: day)
        return gregorianCalendar.date(from: dateComponents)
    }
}

I don't use parse method, but if someone needs, I will update this post.

If you are in a fragment with viewModel scope you can use Kotlin coroutines:

I own a mac too! here is the code that will work:

myButton.setBackground(Color.RED);
myButton.setOpaque(true); //Sets Button Opaque so it works

before doing anything or adding any components set the look and feel so it looks better:

try{
   UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
 }catch(Exception e){
  e.printStackTrace(); 
 }

That is Supposed to change the look and feel to the cross platform look and feel, hope i helped! :)

I had the same problem and fixed it by adding "mousedown touchstart"

$(document).on("mousedown touchstart", ".className", function() { // your code here });

You should definitely check out the MSDN on what Outlook will support in regards to css and html. The link is here: http://msdn.microsoft.com/en-us/library/aa338201(v=office.12).aspx. If you do not have at least office 2007 you really need to upgrade as there are major differences between 2007 and previous editions. Also try saving the resulting email to file and examine it with firefox you will see what is being changed by outlook and possibly have a more specific question to ask. You can use Word to view the email as a sort of preview as well (but you won't get info on what styles are/are not being applied.

There are two methods you can use. Both require creating a user and a database.

1. Using createuser and createdb,

   $ sudo -u postgres createuser --superuser $USER
   $ createdb mydatabase
   $ psql -d mydatabase
   

2. Using the SQL administration commands, and connecting with a password over TCP

   $ sudo -u postgres psql postgres
   

   And, then in the psql shell

   CREATE ROLE myuser LOGIN PASSWORD 'mypass';
   CREATE DATABASE mydatabase WITH OWNER = myuser;
   

   Then you can login,

   $ psql -h localhost -d mydatabase -U myuser -p <port>
   

   If you don't know the port, you can always get it by running the following, as the postgres user,

   SHOW port;
   

   Or,

   $ grep "port =" /etc/postgresql/*/main/postgresql.conf
   

Sidenote: the postgres user

I suggest NOT modifying the postgres user.

1. It's normally locked from the OS. No one is supposed to "log in" to the operating system as postgres. You're supposed to have root to get to authenticate as postgres.
2. It's normally not password protected and delegates to the host operating system. This is a good thing. This normally means in order to log in as postgres which is the PostgreSQL equivalent of SQL Server's SA, you have to have write-access to the underlying data files. And, that means that you could normally wreck havoc anyway.
3. By keeping this disabled, you remove the risk of a brute force attack through a named super-user. Concealing and obscuring the name of the superuser has advantages.

Another option would be to just use the excellent corrr package https://github.com/drsimonj/corrr and do

require(corrr)
require(dplyr)

myData %>% 
   select(x,y,z) %>%  # or do negative or range selections here
   correlate() %>%
   rearrange() %>%  # rearrange by correlations
   shave() # Shave off the upper triangle for a cleaner result

Steps 3 and 4 are entirely optional and are just included to demonstrate the usefulness of the package.

SWIFT 2.0

var tempJson : NSString = ""
do {
    let arrJson = try NSJSONSerialization.dataWithJSONObject(arrInvitationList, options: NSJSONWritingOptions.PrettyPrinted)
    let string = NSString(data: arrJson, encoding: NSUTF8StringEncoding)
    tempJson = string! as NSString
}catch let error as NSError{
    print(error.description)
}

NOTE:- use tempJson variable when you want to use.

Emitting handbuilt html like this is probably the best way so long as the markup isn't too complicated. The stringbuilder only starts to pay you back in terms of efficiency after about three concatenations, so for really simple stuff string + string will do.

Other than that you can start to use the html controls (System.Web.UI.HtmlControls) and render them, that way you can sometimes inherit them and make your own clasess for complex conditional layout.

Here's how you can do it in C#:

class Program
{
    static void Main(string[] args)
    {
        if (File.Exists("test.db3"))
        {
            File.Delete("test.db3");
        }
        using (var connection = new SQLiteConnection("Data Source=test.db3;Version=3"))
        using (var command = new SQLiteCommand("CREATE TABLE PHOTOS(ID INTEGER PRIMARY KEY AUTOINCREMENT, PHOTO BLOB)", connection))
        {
            connection.Open();
            command.ExecuteNonQuery();

            byte[] photo = new byte[] { 1, 2, 3, 4, 5 };

            command.CommandText = "INSERT INTO PHOTOS (PHOTO) VALUES (@photo)";
            command.Parameters.Add("@photo", DbType.Binary, 20).Value = photo;
            command.ExecuteNonQuery();

            command.CommandText = "SELECT PHOTO FROM PHOTOS WHERE ID = 1";
            using (var reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    byte[] buffer = GetBytes(reader);
                }
            }

        }
    }

    static byte[] GetBytes(SQLiteDataReader reader)
    {
        const int CHUNK_SIZE = 2 * 1024;
        byte[] buffer = new byte[CHUNK_SIZE];
        long bytesRead;
        long fieldOffset = 0;
        using (MemoryStream stream = new MemoryStream())
        {
            while ((bytesRead = reader.GetBytes(0, fieldOffset, buffer, 0, buffer.Length)) > 0)
            {
                stream.Write(buffer, 0, (int)bytesRead);
                fieldOffset += bytesRead;
            }
            return stream.ToArray();
        }
    }
}

Complete example based on the excellent @Hackaholic's answer:

def get_process_id(name):
    """Return process ids found by (partial) name or regex.

    >>> get_process_id('kthreadd')
    [2]
    >>> get_process_id('watchdog')
    [10, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61]  # ymmv
    >>> get_process_id('non-existent process')
    []
    """
    child = subprocess.Popen(['pgrep', '-f', name], stdout=subprocess.PIPE, shell=False)
    response = child.communicate()[0]
    return [int(pid) for pid in response.split()]

This should work:

# apt-get install libusb-1.0-0-dev

I'm running Microsoft Windows 10 Pro, Version 10.0.17763 Build 17763, and I see my .ssh folder easily at C:\Users\jrosario\.ssh without having to edit permissions or anything (though in File Explorer, I did select "Show hidden files, folders and drives"):

The keys are stored in a text file named known_hosts, which looks roughly like this:

You have to pass the arguments in the terminal in order to store them in 'argv'. This variable holds the arguments you pass to your Python script when you run it. It later unpacks the arguments and store them in different variables you specify in the program e.g.

script, first, second = argv
print "Your file is:", script
print "Your first entry is:", first
print "Your second entry is:" second

Then in your command line you have to run your code like this,

$python ex14.py Hamburger Pizza

Your output will look like this:

Your file is: ex14.py
Your first entry is: Hamburger
Your second entry is: Pizza

CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.

You can also try the new Array.flat() method. It works in the following manner:

let arr = [["$6"], ["$12"], ["$25"], ["$25"], ["$18"], ["$22"], ["$10"]].flat()

console.log(arr);

The flat() method creates a new array with all sub-array elements concatenated into it recursively up to the 1 layer of depth (i.e. arrays inside arrays)

If you want to also flatten out 3 dimensional or even higher dimensional arrays you simply call the flat method multiple times. For example (3 dimensions):

let arr = [1,2,[3,4,[5,6]]].flat().flat().flat();

console.log(arr);

Be careful!

Array.flat() method is relatively new. Older browsers like ie might not have implemented the method. If you want you code to work on all browsers you might have to transpile your JS to an older version. Check for MDN web docs for current browser compatibility.

I had a similar situation. However I used a different solution.

In my model I create a property that does the dictionary lookup. In the template I then use the property.

In my model: -

@property
def state_(self):
    """ Return the text of the state rather than an integer """
    return self.STATE[self.state]

In my template: -

The state is: {{ item.state_ }}

from jinja2 import Template

def custom_function(a):
    return a.replace('o', 'ay')

template = Template('Hey, my name is {{ custom_function(first_name) }} {{ func2(last_name) }}')
template.globals['custom_function'] = custom_function

You can also give the function in the fields as per Matroskin's answer

fields = {'first_name': 'Jo', 'last_name': 'Ko', 'func2': custom_function}
print template.render(**fields)

Will output:

Hey, my name is Jay Kay

Works with Jinja2 version 2.7.3

Well... I see that an answer was already accepted... but I think you should see another solutions anyway:

You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.

You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig. It will give out some information and your local IP should look like 192.168.1.x.

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;

In Python shape() is use in pandas to give number of row/column:

Number of rows is given by:

train = pd.read_csv('fine_name') //load the data
train.shape[0]

Number of columns is given by

train.shape[1]

If you want to export a table, you can take a look at this export sample provided by the Shield UI Grid widget.

It is done by extending the configuration like this:

...
exportOptions: {
    proxy: "/filesaver/save",
    pdf: {
        fileName: "shieldui-export",
        author: "John Smith",
        dataSource: {
            data: gridData
        },
        readDataSource: true,
        header: {
            cells: [
                { field: "id", title: "ID", width: 50 },
                { field: "name", title: "Person Name", width: 100 },
                { field: "company", title: "Company Name", width: 100 },
                { field: "email", title: "Email Address" }
            ]
        }
    }
}
...

If you want passing parameter and your .exe file in test folder of c: drive

If you won't want passing parameter and your .exe file in test folder of c: drive

start "" "C:\test\test1.exe" -pc My Name-PC -launch

If you won't want passing parameter and your .exe file in test folder of H: (Any Other)drive

}

Your stored procedure is designed to accept a single parameter, Arg1List. You can't pass 4 parameters to a procedure that only accepts one.

To make it work, the code that calls your procedure will need to concatenate your parameters into a single string of no more than 3000 characters and pass it in as a single parameter.

All good answers...From the validation perspective, I also noticed that MaxLength gets validated at the server side only, while StringLength gets validated at client side too.

Here is a slight improvement on the this answer above taking care of both .xlsx and .xls files in the same routine, in case it helps someone!

I also add a line to choose to save with the active sheet name instead of the workbook, which is most practical for me often:

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, InStrRev(CurrentWB.Name, ".") - 1) & ".csv"
    'Optionally, comment previous line and uncomment next one to save as the current sheet name
    'MyFileName = CurrentWB.Path & "\" & CurrentWB.ActiveSheet.Name & ".csv"


    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

Go to --> file --> Project Structure --> Global Libraries ==> set to JDK 1.8 or higher version.

also File -- > project Structure ---> projects ===> set "project language manual" to 8

also File -- > project Structure ---> project sdk ==> 1.8

This should enable lambda expression for your project.

Just for the record and in case you have a browser supporting ES6, here's a solution with reduce:

Object.keys(obj).reduce((prev, key, i) => (
  `${prev}${i!==0?'&':''}${key}=${obj[key]}`
), '');

And here's a snippet in action!

// Just for test purposes_x000D_
let obj = {param1: 12, param2: "test"};_x000D_
_x000D_
// Actual solution_x000D_
let result = Object.keys(obj).reduce((prev, key, i) => (_x000D_
  `${prev}${i!==0?'&':''}${key}=${obj[key]}`_x000D_
), '');_x000D_
_x000D_
// Run the snippet to show what happens!_x000D_
console.log(result);

Late to this one, but I just discovered an alternative way of doing it:

On your template,

<a (click)="navigateAssociates()">Associates</a> 

And on your component.ts, you can use serializeUrl to convert the route into a string, which can be used with window.open()

navigateAssociates() {
  const url = this.router.serializeUrl(
    this.router.createUrlTree(['/page1'])
  );

  window.open(url, '_blank');
}

As many of the answer suggesting better solution is to use ArrayList. ArrayList size is not fixed and it is easily manageable.

It is resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list.

Each ArrayList instance has a capacity. The capacity is the size of the array used to store the elements in the list. It is always at least as large as the list size. As elements are added to an ArrayList, its capacity grows automatically.

Note that this implementation is not synchronized.

ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test1");
scripts.add("test2");
scripts.add("test3");

It is there to specify another column as the default id column of the other table, e.g. consider the following

TableA
  id int identity
  tableb_key varchar


TableB
  id int identity
  key varchar unique

// in class for TableA
@JoinColumn(name="tableb_key", referencedColumnName="key")

You could try:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.ToArray());

Not sure if .ToArray() is available for the collection. If you do use the code you posted, make sure you initialize the List with the number of existing elements:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.Count);  // or .Length

You can use templated interfaces like this:

interface Map<T> {
    [K: string]: T;
}

let dict: Map<number> = {};
dict["one"] = 1;

Another option would be:

$scope.parseInt = parseInt;

Then you could do this like you wanted:

{{parseInt(num_str)-1}}

This is because angular expressions don't have access to the window, only to scope.

Also, with the number filter, wrapping your expression in parentheses works:

{{(num_str-1) | number}}

DEMO

The following works for me:

CAST(GETDATE() AS CHAR(3))

validate: It validates the schema and makes no changes to the DB.
Assume you have added a new column in the mapping file and perform the insert operation, it will throw an Exception "missing the XYZ column" because the existing schema is different than the object you are going to insert. If you alter the table by adding that new column manually then perform the Insert operation then it will definitely insert all columns along with the new column to the Table. Means it doesn't make any changes/alters the existing schema/table.

update: it alters the existing table in the database when you perform operation. You can add or remove columns with this option of hbm2ddl. But if you are going to add a new column that is 'NOT NULL' then it will ignore adding that particular column to the DB. Because the Table must be empty if you want to add a 'NOT NULL' column to the existing table.

in angular4 foreach like that. try this.

 selectChildren(data, $event) {
      let parentChecked = data.checked;
       this.hierarchicalData.forEach(obj => {
          obj.forEach(childObj=> {
            value.checked = parentChecked;
         });
      });
    }

If your app is launched from device, not IDE, you can do later in menu: Run - Attach Debugger to Android Process.

This can be useful when debugging notifications on closed application.

Try this:

$('select option:selected').prop('label');

This will pull out the displayed text for both styles of <option> elements:

• <option label="foo"><option> -> "foo"
• <option>bar<option> -> "bar"

If it has both a label attribute and text inside the element, it'll use the label attribute, which is the same behavior as the browser.

For posterity, this was tested under jQuery 3.1.1

If you want to keep the row with the lowest id value:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MIN(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

If you want the id value that is the highest:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MAX(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

The subquery in a subquery is necessary for MySQL, or you'll get a 1093 error.

<div  style="display:none;" class="answer_list" > WELCOME</div>
<input type="button" name="answer" onclick="document.getElementsByClassName('answer_list')[0].style.display = 'auto';">

Quite and simple without any "having to specify the first element". CSS is more powerful than most think (e.g. the first-child:before is great!). But this is by far the cleanest and most proper way to do this, at least in my opinion it is.

#navigation ul
{
    margin: 0;
    padding: 0;
}

#navigation ul li
{
    list-style-type: none;
    display: inline;
}

#navigation li:not(:first-child):before {
    content: " | ";
}

Now just use a simple unordered list in HTML and it'll populate it for you. HTML should look like this:

<div id="navigation">
    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">About Us</a></li>
        <li><a href="#">Support</a></li>
    </ul>
</div><!-- navigation -->

The result will be just like this:

HOME | ABOUT US | SUPPORT

Now you can indefinitely expand and never have to worry about order, changing links, or your first entry. It's all automated and works great!

This is short, yet efficient and proven approach:

location ~ (patternOne|patternTwo){ #rules etc. }

So one can easily have multiple patterns with simple pipe syntax pointing to the same location block / rules.

<?php //initialize the session if (!isset($_SESSION)) {   session_start(); } 
// ** Logout the current user. **
$logoutAction = $_SERVER['PHP_SELF']."?doLogout=true";
if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){
    $logoutAction .= "&". htmlentities($_SERVER['QUERY_STRING']); 
}

if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")) {
    // to fully log out a visitor we need to clear the session variables
    $_SESSION['MM_Username'] = NULL;
    $_SESSION['MM_UserGroup'] = NULL;
    $_SESSION['PrevUrl'] = NULL;
    unset($_SESSION['MM_Username']);  
    unset($_SESSION['MM_UserGroup']);
    unset($_SESSION['PrevUrl']);
    $logoutGoTo = "index.php";

    if ($logoutGoTo) {
        header("Location: $logoutGoTo");
        exit;
    }
} ?>

Opening Visual Studio as administrator will fix the problem.

Mongoose now supports the timestamps in schema.

const item = new Schema(
  {
    id: {
      type: String,
      required: true,
    },
  { timestamps: true },
);

This will add the createdAt and updatedAt fields on each record create.

Timestamp interface has fields

  interface SchemaTimestampsConfig {
    createdAt?: boolean | string;
    updatedAt?: boolean | string;
    currentTime?: () => (Date | number);
  }

This would help us to choose which fields we want and overwrite the date format.

In php, we have two option to concatenate table columns.

First Option using Query

In query, CONCAT keyword used to concatenate two columns

SELECT CONCAT(`SUBJECT`,'_', `YEAR`) AS subject_year FROM `table_name`;

Second Option using symbol ( . )

After fetch the data from database table, assign the values to variable, then using ( . ) Symbol and concatenate the values

$subject = $row['SUBJECT'];
$year = $row['YEAR'];
$subject_year = $subject . "_" . $year;

Instead of underscore( _ ) , we will use the spaces, comma, letters,numbers..etc

Another feature is between:

Select * from table where date between '2009/01/30' and '2009/03/30'

I also encountered the same issue. The best way to resolve is (for windows):

1. Go to the Task Manager.

2. Scroll and find a task process named. Node.js: Server-side JavaScript

3. End this particular task.

There you go! Now do npm start and it will work as before!

First of all, I don't see the reason for having an ID that's not unique, but I guess it's an ID that connects to another table. Second there is no need for subqueries, which beats up the server. You do this in one query, like this

SELECT id,GROUP_CONCAT(name, ':', value SEPARATOR "|") FROM sample GROUP BY id

You get fast and correct results, and you can split the result by that SEPARATOR "|". I always use this separator, because it's impossible to find it inside a string, therefor it's unique. There is no problem having two A's, you identify only the value. Or you can have one more colum, with the letter, which is even better. Like this :

SELECT id,GROUP_CONCAT(DISTINCT(name)), GROUP_CONCAT(value SEPARATOR "|") FROM sample GROUP BY name

DECLARE @variable VARCHAR(100) = 'LD-23DSP-1430';
WITH    Split
      AS ( SELECT   @variable AS list ,
                    charone = LEFT(@variable, 1) ,
                    R = RIGHT(@variable, LEN(@variable) - 1) ,
                    'A' AS MasterOne
           UNION ALL
           SELECT   Split.list ,
                    LEFT(Split.R, 1) ,
                    R = RIGHT(split.R, LEN(Split.R) - 1) ,
                    'B' AS MasterOne
           FROM     Split
           WHERE    LEN(Split.R) > 0
         )
SELECT  *
FROM    Split
OPTION  ( MAXRECURSION 10000 );

I use GET/204 with a RESTful collection that is a positional array of known fixed length but with holes.

GET /items
    200: ["a", "b", null]

GET /items/0
    200: "a"

GET /items/1
    200: "b"

GET /items/2
    204:

GET /items/3
    404: Not Found

One of the best approach if you do not want to return any columns from table2 is to use the NOT EXISTS

SELECT  table1.id 
FROM    table1 T1
WHERE
  NOT EXISTS (SELECT *
              FROM table2 T2
              WHERE T1.id = T2.user_one
                  OR T1.id = T2.user_two)

Semantically this says what you want to query: Select every row where there is no matching record in the second table.

MySQL is optimized for EXISTS: It returns as soon as it finds the first matching record.

As of today (2014/09/23), I've found that to get marker on exact place (not an approximation) you can use:

http://www.google.com/maps/place/49.46800006494457,17.11514008755796

Additionally, if you want to specify map center and zoom:

http://www.google.com/maps/place/49.46800006494457,17.11514008755796/@49.46800006494457,17.11514008755796,17z

If you want to use satellite map type, then append /data=!3m1!1e3

http://www.google.com/maps/place/49.46800006494457,17.11514008755796/@49.46800006494457,17.11514008755796,17z/data=!3m1!1e3

And If you want terrain view of the map, then append /data=!3m1!4b1

https://www.google.com/maps/place/49.46800006494457,17.11514008755796/@49.46800006494457,17.11514008755796,17z/data=!3m1!4b1

From the ECMAScript specification in section 7.6 Identifier Names and Identifiers, a valid identifier is defined as:

Identifier :: 
    IdentifierName but not ReservedWord

IdentifierName :: 
    IdentifierStart 
    IdentifierName IdentifierPart 

IdentifierStart :: 
    UnicodeLetter 
    $ 
    _ 
    \ UnicodeEscapeSequence 

IdentifierPart :: 
    IdentifierStart 
    UnicodeCombiningMark 
    UnicodeDigit 
    UnicodeConnectorPunctuation 
    \ UnicodeEscapeSequence 

UnicodeLetter 
    any character in the Unicode categories “Uppercase letter (Lu)”, “Lowercase letter (Ll)”, “Titlecase letter (Lt)”, 
    “Modifier letter (Lm)”, “Other letter (Lo)”, or “Letter number (Nl)”. 

UnicodeCombiningMark 
    any character in the Unicode categories “Non-spacing mark (Mn)” or “Combining spacing mark (Mc)” 

UnicodeDigit 
    any character in the Unicode category “Decimal number (Nd)” 

UnicodeConnectorPunctuation 
    any character in the Unicode category “Connector punctuation (Pc)” 

UnicodeEscapeSequence 
    see 7.8.4. 

HexDigit :: one of 
    0 1 2 3 4 5 6 7 8 9 a b c d e f A B C D E F

which creates a lot of opportunities for naming variables and also in golfing. Let's try some examples.

A valid identifier could start with either a UnicodeLetter, $, _, or \ UnicodeEscapeSequence. A unicode letter is any character from these categories (see all categories):

• Uppercase letter (Lu)
• Lowercase letter (Ll)
• Titlecase letter (Lt)
• Modifier letter (Lm)
• Other letter (Lo)
• Letter number (Nl)

This alone accounts for some crazy possibilities - working examples. If it doesn't work in all browsers, then call it a bug, cause it should.

var ? = "something";
var HELLO = "hello";
var ???? = "less than? wtf";
var ????????????? = "javascript"; // ok that's JavaScript in hindi
var KingGeorge? = "Roman numerals, awesome!";

You can do this.

data[0]['f'] = var

Calling multiple functions on onClick for any element, you can create a wrapper function, something like this.

wrapperFunction = () => {
    //do something
    function 1();
    //do something
    function 2();
    //do something
    function 3();
}

These functions can be defined as a method on the parent class and then called from the wrapper function.

You may have the main element which will cause the onChange like this,

<a href='#' onClick={this.wrapperFunction}>Some Link</a>

This works for me:

sudo apt-get install php5.6-curl

Well presumably it's not using the same version of Java when running it externally. Look through the startup scripts carefully to find where it picks up the version of Java to run. You should also check the startup logs to see whether they indicate which version is running.

Alternatively, unless you need the Java 7 features, you could always change your compiler preferences in Eclipse to target 1.6 instead.

Use concat() function instead of + like this:

select concat(firstname, lastname) as "Name" from test.student

This is the way I did it:

I just put

Intent intent = new Intent(Main.this, SOMECLASSNAME.class);
Main.this.startActivityForResult(intent, 0);

inside of the method that opens an activity, then inside of the method of SOMECLASSNAME that is designed to close the app I put:

setResult(0);
finish();

And I put the following in my Main class:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode == 0) {
        finish();
    }
}

This doesn't remove whitespace automatically before a commit, but it is pretty easy to effect. I put the following perl script in a file named git-wsf (git whitespace fix) in a dir in $PATH so I can:

git wsf | sh

and it removes all whitespace only from lines of files that git reports as a diff.

#! /bin/sh
git diff --check | perl -x $0
exit

#! /usr/bin/perl

use strict;

my %stuff;
while (<>) {
    if (/trailing whitespace./) {
        my ($file,$line) = split(/:/);
        push @{$stuff{$file}},$line;
    }
}

while (my ($file, $line) = each %stuff) {
    printf "ex %s <<EOT\n", $file;
    for (@$line) {
        printf '%ds/ *$//'."\n", $_;
    }
    print "wq\nEOT\n";
}

This is an issue of selector specificity. (The selector .selected is less specific than ul.nav li.)

To fix, use as much specificity in the overriding rule as in the original:

ul.nav li {
 background-color:blue;
}
ul.nav li.selected {
 background-color:red;
}

You might also consider nixing the ul, unless there will be other .navs. So:

.nav li {
 background-color:blue;
}
.nav li.selected {
 background-color:red;
}

That's a bit cleaner, less typing, and fewer bits.

open windows powershell, run as administrater and SetExecution policy as Unrestricted then it will work.

Quick Description of AJAX

AJAX is simply Asyncronous JSON or XML (in most newer situations JSON). Because we are doing an ASYNC task we will likely be providing our users with a more enjoyable UI experience. In this specific case we are doing a FORM submission using AJAX.

Really quickly there are 4 general web actions GET, POST, PUT, and DELETE; these directly correspond with SELECT/Retreiving DATA, INSERTING DATA, UPDATING/UPSERTING DATA, and DELETING DATA. A default HTML/ASP.Net webform/PHP/Python or any other form action is to "submit" which is a POST action. Because of this the below will all describe doing a POST. Sometimes however with http you might want a different action and would likely want to utilitize .ajax.

My code specifically for you (described in code comments):

/* attach a submit handler to the form */
$("#formoid").submit(function(event) {

  /* stop form from submitting normally */
  event.preventDefault();

  /* get the action attribute from the <form action=""> element */
  var $form = $(this),
    url = $form.attr('action');

  /* Send the data using post with element id name and name2*/
  var posting = $.post(url, {
    name: $('#name').val(),
    name2: $('#name2').val()
  });

  /* Alerts the results */
  posting.done(function(data) {
    $('#result').text('success');
  });
  posting.fail(function() {
    $('#result').text('failed');
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<form id="formoid" action="studentFormInsert.php" title="" method="post">
  <div>
    <label class="title">First Name</label>
    <input type="text" id="name" name="name">
  </div>
  <div>
    <label class="title">Last Name</label>
    <input type="text" id="name2" name="name2">
  </div>
  <div>
    <input type="submit" id="submitButton" name="submitButton" value="Submit">
  </div>
</form>

<div id="result"></div>

Documentation

From jQuery website $.post documentation.

Example: Send form data using ajax requests

$.post("test.php", $("#testform").serialize());

Example: Post a form using ajax and put results in a div

                    url = $form.attr('action');

                /* Send the data using post */
                var posting = $.post(url, {
                    s: term
                });

                /* Put the results in a div */
                posting.done(function(data) {
                    var content = $(data).find('#content');
                    $("#result").empty().append(content);
                });
            });

Important Note

Without using OAuth or at minimum HTTPS (TLS/SSL) please don't use this method for secure data (credit card numbers, SSN, anything that is PCI, HIPAA, or login related)

var startDate = new Date($('#startDate').val());
var endDate = new Date($('#endDate').val());

if (startDate < endDate){
// Do something
}

That should do it I think

if you have error in Sqlite built in python you can use Conda to solve this conflict

conda install sqlite

The point against parseInt-approach:

There's no need to use lambdas and/or give radix parameter to parseInt, just use parseFloat or Number instead.

Reasons:

1. It's working:

   var src = "1,2,5,4,3";
   var ids = src.split(',').map(parseFloat); // [1, 2, 5, 4, 3]
   
   var obj = {1: ..., 3: ..., 4: ..., 7: ...};
   var keys= Object.keys(obj); // ["1", "3", "4", "7"]
   var ids = keys.map(parseFloat); // [1, 3, 4, 7]
   
   var arr = ["1", 5, "7", 11];
   var ints= arr.map(parseFloat); // [1, 5, 7, 11]
   ints[1] === "5" // false
   ints[1] === 5   // true
   ints[2] === "7" // false
   ints[2] === 7   // true
   

2. It's shorter.

3. It's a tiny bit quickier and takes advantage of cache, when parseInt-approach - doesn't:

     // execution time measure function
     // keep it simple, yeah?
   > var f = (function (arr, c, n, m) {
         var i,t,m,s=n();
         for(i=0;i++<c;)t=arr.map(m);
         return n()-s
     }).bind(null, "2,4,6,8,0,9,7,5,3,1".split(','), 1000000, Date.now);
   
   > f(Number) // first launch, just warming-up cache
   > 3971 // nice =)
   
   > f(Number)
   > 3964 // still the same
   
   > f(function(e){return+e})
   > 5132 // yup, just little bit slower
   
   > f(function(e){return+e})
   > 5112 // second run... and ok.
   
   > f(parseFloat)
   > 3727 // little bit quicker than .map(Number)
   
   > f(parseFloat)
   > 3737 // all ok
   
   > f(function(e){return parseInt(e,10)})
   > 21852 // awww, how adorable...
   
   > f(function(e){return parseInt(e)})
   > 22928 // maybe, without '10'?.. nope.
   
   > f(function(e){return parseInt(e)})
   > 22769 // second run... and nothing changes.
   
   > f(Number)
   > 3873 // and again
   > f(parseFloat)
   > 3583 // and again
   > f(function(e){return+e})
   > 4967 // and again
   
   > f(function(e){return parseInt(e,10)})
   > 21649 // dammit 'parseInt'! >_<
   

Notice: In Firefox parseInt works about 4 times faster, but still slower than others. In total: +e < Number < parseFloat < parseInt

You can also see this error when selecting for a union where corresponding columns can be null.

select * from (select D.dept_no, D.nullable_comment
                  from dept D
       union
               select R.dept_no, NULL
                 from redundant_dept R
)

This apparently confuses the parser, a solution is to assign a column alias to the always null column.

select * from (select D.dept_no, D.comment
                  from dept D
       union
               select R.dept_no, NULL "nullable_comment"
                 from redundant_dept R
)

The alias does not have to be the same as the corresponding column, but the column heading in the result is driven by the first query from among the union members, so it's probably a good practice.

In newer Android Studio, there is a GUI way which is very easy and it populates Gradle file as well.

1. File -> Project Structure

2. Module -> Choose the main module ('app' or other custom name)

3. Signing tab -> Plus image to add new configuration

4. Fill data on the right side

5. OK and Gradle file is automatically created

6. You will manually have to add a line signingConfig signingConfigs.NameOfYourConfig inside builtTypes{release{}}

Images:

Two important(!) notes:

(EDIT 12/15)

1. To create signed APK, you'd have to open Terminal tab of Android Studio (the bottom of the main interface) and issue a command ./gradlew assembleRelease

2. If you forgot keyAlias (what happens often to me), you will have to initiate Build -> Generate Signed APK to start the process and see the name of the Alias key.

raw.githubusercontent.com/username/repo-name/branch-name/path

Replace username with the username of the user that created the repo.

Replace repo-name with the name of the repo.

Replace branch-name with the name of the branch.

Replace path with the path to the file.

To reverse to go to GitHub.com:

GitHub.com/username/repo-name/directory-path/blob/branch-name/filename

See here http://dev.mysql.com/doc/refman/5.0/en/connecting.html

mysql -u USERNAME -pPASSWORD -h HOSTNAMEORIP DATABASENAME 

The options above means:

-u: username
-p: password (**no space between -p and the password text**)
-h: host
last one is name of the database that you wanted to connect. 

Look into the link, it's detailed there!

As already mentioned by Rick, you can avoid passing the password as the part of the command by not passing the password like this:

mysql -u USERNAME -h HOSTNAMEORIP DATABASENAME -p

People editing this answer: PLEASE DONOT ADD A SPACE between -p and PASSWORD

Make sure external storage is present: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal

private boolean isExternalStoragePresent() {

        boolean mExternalStorageAvailable = false;
        boolean mExternalStorageWriteable = false;
        String state = Environment.getExternalStorageState();

        if (Environment.MEDIA_MOUNTED.equals(state)) {
            // We can read and write the media
            mExternalStorageAvailable = mExternalStorageWriteable = true;
        } else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
            // We can only read the media
            mExternalStorageAvailable = true;
            mExternalStorageWriteable = false;
        } else {
            // Something else is wrong. It may be one of many other states, but
            // all we need
            // to know is we can neither read nor write
            mExternalStorageAvailable = mExternalStorageWriteable = false;
        }
        if (!((mExternalStorageAvailable) && (mExternalStorageWriteable))) {
            Toast.makeText(context, "SD card not present", Toast.LENGTH_LONG)
                    .show();

        }
        return (mExternalStorageAvailable) && (mExternalStorageWriteable);
    }

In my case, the problem was another. I was trying convert lists of lists of int to array. The problem was that there was one list with a different length than others. If you want to prove it, you must do:

print([i for i,x in enumerate(list) if len(x) != 560])

In my case, the length reference was 560.

Maybe you can run this regex first to see if the line is all caps:

^[A-Z \d\W]+$

That will match only if it's a line like THING P1 MUST CONNECT TO X2.

Otherwise, you should be able to pull out the individual uppercase phrases with this:

[A-Z][A-Z\d]+

That should match "P1" and "J236" in The thing P1 must connect to the J236 thing in the Foo position.

I've found this to work the best across all browsers and devices (PC, tables & mobile).

<script type="text/javascript">
                      function iframeLoaded() {
                          var iFrameID = document.getElementById('idIframe');
                          if(iFrameID) {
                                // here you can make the height, I delete it first, then I make it again
                                iFrameID.height = "";
                                iFrameID.height = iFrameID.contentWindow.document.body.scrollHeight + "px";
                          }   
                      }
                    </script> 


<iframe id="idIframe" onload="iframeLoaded()" frameborder="0" src="yourpage.php" height="100%" width="100%" scrolling="no"></iframe>

Hope this layout works, take it to the binary representation with an XOR:

66h = 102 decimal = 01100110 binary
FAh = 250 decimal = 11111010 binary
------------------------------------
                    10011100 binary <------ that's 9Ch/156 decimal

XOR rules are basically:
• 1 XOR 1 = 0 false
• 1 XOR 0 = 1 true
• 0 XOR 0 = 0 false

but the wiki I linked earlier will give you more details if needed...thats what it looks like they are doing in the screenshot you provided

Try this one in your css document,

-fx-background-color : #ffaadd;

or

-fx-base : #ffaadd; 

Also, you can set background color on your object with this code directly.

yourPane.setBackground(new Background(new BackgroundFill(Color.DARKGREEN, CornerRadii.EMPTY, Insets.EMPTY)));

public class Matrix 
{
   public static void main(String[] args)
   {
      double Matrix [] []={
         {0*1,0*2,0*3,0*4),
         {0*1,1*1,2*1,3*1),
         {0*2,1*2,2*2,3*2),
         {0*3,1*3,2*3,3*3)
      };

      int i,j;
      for(i=0;i<4;i++)
      {
         for(j=0;j<4;j++)
            System.out.print(Matrix [i] [j] + " ");
         System.out.println();
      }
   }
}

You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):

dataGridView1.Columns[1].Width = 108;  // or whatever width works well for abbrev
dataGridView1.Columns[2].Width = 
    dataGridView1.Width 
    - dataGridView1.Columns[0].Width 
    - dataGridView1.Columns[1].Width 
    - 72;  // this is an extra "margin" number of pixels

If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize event handler of the DataGridView.

Another option is to pass the single quote as an awk variable:

awk -v q=\' 'BEGIN {FS=" ";} {printf "%s%s%s ", q, $1, q}'

Simpler example with string concatenation:

# Prints 'test me', *including* the single quotes.
$ awk -v q=\' '{print q $0 q }' <<<'test me'
'test me'

May be it is the problem of using len() for an integer value. does not posses the len attribute in Python.

Error as:I will give u an example:

number= 1
print(len(num))

Instead of use ths,

data = [1,2,3,4]
print(len(data))

If you use MySQL Workbench you can right-click your table and click Send to sql editor and then Select All Statement This will create an statement where all fields are listed, like this:

SELECT `purchase_history`.`id`,
    `purchase_history`.`user_id`,
    `purchase_history`.`deleted_at`
FROM `fs_normal_run_2`.`purchase_history`;
SELECT * FROM fs_normal_run_2.purchase_history;

Now you can just remove those that you dont want.

mToolbar.setNavigationIcon(R.mipmap.ic_launcher);
mToolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_menu));

Create Parcelable class without plugin in Android Studio

implements Parcelable in your class and then put cursor on "implements Parcelable" and hit Alt+Enter and select Add Parcelable implementation (see image). that's it.

Make sure that both projects have same target framework version here: right click on project -> properties -> application (tab) -> target framework

Also, make sure that the project "logger" (which you want to include in the main project) has the output type "Class Library" in: right click on project -> properties -> application (tab) -> output type

Finally, Rebuild the solution.

If you are not using jQuery then I would simply write a validation method that you can be fired when the form is submitted. The method can validate the text fields to make sure that they are not empty or the default value. The method will return a bool value and if it is false you can fire off your alert and assign classes to highlight the fields that did not pass validation.

HTML:

<form name="form1" method="" action="" onsubmit="return validateForm(this)">
<input type="text" name="name" value="Name"/><br />
<input type="text" name="addressLine01" value="Address Line 1"/><br />
<input type="submit"/>
</form>

JavaScript:

function validateForm(form) {

    var nameField = form.name;
    var addressLine01 = form.addressLine01;

    if (isNotEmpty(nameField)) {
        if(isNotEmpty(addressLine01)) {
            return true;
        {
    {
    return false;
}

function isNotEmpty(field) {

    var fieldData = field.value;

    if (fieldData.length == 0 || fieldData == "" || fieldData == fieldData) {

        field.className = "FieldError"; //Classs to highlight error
        alert("Please correct the errors in order to continue.");
        return false;
    } else {

        field.className = "FieldOk"; //Resets field back to default
        return true; //Submits form
    }
}

The validateForm method assigns the elements you want to validate and then in this case calls the isNotEmpty method to validate if the field is empty or has not been changed from the default value. it continuously calls the inNotEmpty method until it returns a value of true or if the conditional fails for that field it will return false.

Give this a shot and let me know if it helps or if you have any questions. of course you can write additional custom methods to validate numbers only, email address, valid URL, etc.

If you use jQuery at all I would look into trying out the jQuery Validation plug-in. I have been using it for my last few projects and it is pretty nice. Check it out if you get a chance. http://docs.jquery.com/Plugins/Validation

After doing an insert into a table with an identity column, you can reference @@IDENTITY to get the value: http://msdn.microsoft.com/en-us/library/aa933167%28v=sql.80%29.aspx

In my case, all other solutions didn't work, but this one did:

obj = {...arr}

my arr is in a form: [name: "the name", email: "[email protected]"]

I thought that many (as myself) could be more interested in a common case of traversing an existing list in reversed order instead, as it's stated in the title, rather than just generating indices for such traversal.

Even though, all the right answers are still perfectly fine for this case, I want to point out that the performance comparison done in Wolf's answer is for generating indices only. So I've made similar benchmark for traversing an existing list in reversed order.

TL;DR a[::-1] is the fastest.

NB: If you want more detailed analysis of different reversal alternatives and their performance, check out this great answer.

Prerequisites:

a = list(range(10))

Jason's answer:

%timeit [a[9-i] for i in range(10)]
1.27 µs ± 61.5 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

martineau's answer:

%timeit a[::-1]
135 ns ± 4.07 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

Michal Šrajer's answer:

%timeit list(reversed(a))
374 ns ± 9.87 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

bene's answer:

%timeit [a[i] for i in range(9, -1, -1)]
1.09 µs ± 11.1 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

As you see, in this case there's no need to explicitly generate indices, so the fastest method is the one that makes less extra actions.

NB: I tested in JupyterLab which has handy "magic command" %timeit. It uses standard timeit.timeit under the hood. Tested for Python 3.7.3

Use count()

if (count($my_array) > 1) {
// do
}

this page explains it pretty well http://phparraylength.com/

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

Giving write permissions to all IIS_USRS group is a bad idea from the security point of view. You dont need to do that and you can go with giving permissions only to system user running the application pool.

If you are using II7 (and I guess you do) do the following.

1. Open IIS7
2. Select Website for which you need to modify permissions
3. Go to Basic Settings and see which application pool you're using.
4. Go to Application pools and find application pool from #3
5. Find system account used for running this application pool (Identity column)
6. Navigate to your storage folder in IIS, select it and click on Edit Permissions (under Actions sub menu on the right)
7. Open security tab and add needed permissions only for user you identified in #3

Note #1: if you see ApplicationPoolIdentity in #3 you need to reference this system user like this IIS AppPool{application_pool_name} . For example IIS AppPool\DefaultAppPool

Note #2: when adding this user make sure to set correct locations in the Select Users or Groups dialog. This needs to be set to local machine because this is local account.

Ex Microsoft Developer's Opinion

I worked on a core team for the MSDN website. Now, I use c# razor for ecommerce sites with my programming team and we focus heavy on jQuery front end with back end c# razor pages and LINQ-Entity memory database so the pages are 1-2 millisecond response times even on nested for loops with queries and no page caching. We don't use MVC, just plain ASP.NET with razor pages being mapped with URL Rewrite module for IIS 7, no ASPX pages or ViewState or server-side event programming at all. It doesn't have the extra (unnecessary) layers MVC puts in code constructs for the regex challenged. Less is more for us. Its all lean and mean but I give props to MVC for its testability but that's all.

Razor pages have no event life cycle like ASPX pages. Its just rendering as one requested page. C# is such a great language and Razor gets out of its way nicely to let it do its job. The anonymous typing with generics and linq make life so easy with c# and razor pages. Using Razor pages will help you think and code lighter.

One of the drawback of Razor and MVC is there is no ViewState-like persistence. I needed to implement a solution for that so I ended up writing a jQuery plugin for that here -> http://www.jasonsebring.com/dumbFormState which is an HTML 5 offline storage supported plugin for form state that is working in all major browsers now. It is just for form state currently but you can use window.sessionStorage or window.localStorage very simply to store any kind of state across postbacks or even page requests, I just bothered to make it autosave and namespace it based on URL and form index so you don't have to think about it.

Try using matplotlib.pyplot.ticklabel_format:

import matplotlib.pyplot as plt
...
plt.ticklabel_format(style='sci', axis='x', scilimits=(0,0))

This applies scientific notation (i.e. a x 10^b) to your x-axis tickmarks

It's Date.getTime().
