A framework helps us about using the "already created", a metaphore can be like,

think that earth material is the programming language,

and for example "a camera" is the program, and you decided to create a notebook. You don't need to recreate the camera everytime, you just use the earth framework (for example to a technology store) take the camera and integrate it to your notebook.

In order to check the absence of physical sockets run:

wmic cpu get SocketDesignation

This is the documentation that you want: http://msdn.microsoft.com/en-us/library/aa292114(VS.71).aspx

I guess the answer is, yes, there is an equivalent that will accomplish the same thing, integrated with Windows security.

Try below structure for applying two color border,

<div class="white">
    <div class="grey">
    </div>
</div>

.white
{
    border: 2px solid white;   
}

.grey
{
    border: 1px solid grey;   
}

To add something to this (cause I found it while searching on this problem, and my solution involved slightly more)...

If you don't have a "Browse with..." option for .aspx files (as I didn't in a MVC application), the easiest solution is to add a dummy HTML file, and right-click it to set the option as described in the answer. You can remove the file afterward.

The option is actually set in: C:\Documents and Settings[user]\Local Settings\Application Data\Microsoft\VisualStudio[version]\browser.xml

However, if you modify the file directly while VS is running, VS will overwrite it with your previous option on next run. Also, if you edit the default in VS you won't have to worry about getting the schema right, so the work-around dummy file is probably the easiest way.

pytest --capture=tee-sys was recently added (v5.4.0). You can capture as well as see the output on stdout/err.

UITableView has a tableHeaderView property. Set that to whatever view you want up there.

Use a new UIView as a container, add a text label and an image view to that new UIView, then set tableHeaderView to the new view.

For example, in a UITableViewController:

-(void)viewDidLoad
{
     // ...
     UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     [headerView addSubview:imageView];
     UILabel *labelView = [[UILabel alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     [headerView addSubview:labelView];
     self.tableView.tableHeaderView = headerView;
     [imageView release];
     [labelView release];
     [headerView release];
     // ...
} 

It is not possible prolly cuz it would be so easy to XSS. Also , current HTML sanitizers that are available don't disallow content property.

(Definitely not the greatest answer here but I just wanted to share an insight other than the "according to spec... ")

You need to use entryComponents under @NgModule.

This is for dynamically added components that are added using ViewContainerRef.createComponent(). Adding them to entryComponents tells the offline template compiler to compile them and create factories for them.

The components registered in route configurations are added automatically to entryComponents as well because router-outlet also uses ViewContainerRef.createComponent() to add routed components to the DOM.

So your code will be like

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    DashboardComponent,
    HomeComponent,
    DialogResultExampleDialog        
  ],
  entryComponents: [DialogResultExampleDialog]

This is an old post, but thanks to this post I have found this:

\! echo 'some text';

Tested with MySQL 8 and working correctly. Cool right? :)

The Get-ChildItem cmdlet has an -Exclude parameter that is tempting to use but it doesn't work for filtering out entire directories from what I can tell. Try something like this:

function GetFiles($path = $pwd, [string[]]$exclude) 
{ 
    foreach ($item in Get-ChildItem $path)
    {
        if ($exclude | Where {$item -like $_}) { continue }

        if (Test-Path $item.FullName -PathType Container) 
        {
            $item 
            GetFiles $item.FullName $exclude
        } 
        else 
        { 
            $item 
        }
    } 
}

Currently there is a far simpler solution than the ones already provided. When running your application you just have to pass along the threaded=True parameter to the app.run() call, like:

app.run(host="your.host", port=4321, threaded=True)

Another option as per what we can see in the werkzeug docs, is to use the processes parameter, which receives a number > 1 indicating the maximum number of concurrent processes to handle:

• threaded – should the process handle each request in a separate thread?
• processes – if greater than 1 then handle each request in a new process up to this maximum number of concurrent processes.

Something like:

app.run(host="your.host", port=4321, processes=3) #up to 3 processes

More info on the run() method here, and the blog post that led me to find the solution and api references.

Note: on the Flask docs on the run() methods it's indicated that using it in a Production Environment is discouraged because (quote): "While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well."

However, they do point to their Deployment Options page for the recommended ways to do this when going for production.

I used Mercury/32 and Pegasus Mail to get the mail() functional. It works great too as a mail server if you want an email address ending with your domain name.

Heres an easy option. Just set your list option then set its text as selected value:

$("#ddlScheduleFrequency option").selected(text("Select One..."));

You can put the data in a file and re-direct it like this:

$ cat file.sh
#!/bin/bash

read x
read y
echo $x
echo $y

Data for the script:

$ cat data.txt
2
3

Executing the script:

$ file.sh < data.txt
2

What is Stroke:

The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke.

https://docs.oracle.com/javase/7/docs/api/java/awt/BasicStroke.html

Note that the Stroke setting:

Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));

is setting the line width,since BasicStroke(float width):

Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles.

And, it also effects other methods like Graphics2D.drawLine(int x1, int y1, int x2, int y2) and Graphics2D.drawRect(int x, int y, int width, int height):

The methods of the Graphics2D interface that use the outline Shape returned by a Stroke object include draw and any other methods that are implemented in terms of that method, such as drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon.

I know three ways of converting String into int:

Either use stoi(String to int) function or just go with Stringstream, the third way to go individual conversion, Code is below:

1st Method

std::string s1 = "4533";
std::string s2 = "3.010101";
std::string s3 = "31337 with some string";

int myint1 = std::stoi(s1);
int myint2 = std::stoi(s2);
int myint3 = std::stoi(s3);

std::cout <<  s1 <<"=" << myint1 << '\n';
std::cout <<  s2 <<"=" << myint2 << '\n';
std::cout <<  s3 <<"=" << myint3 << '\n';

2nd Method

#include <string.h>
#include <sstream>
#include <iostream>
#include <cstring>
using namespace std;


int StringToInteger(string NumberAsString)
{
    int NumberAsInteger;
    stringstream ss;
    ss << NumberAsString;
    ss >> NumberAsInteger;
    return NumberAsInteger;
}
int main()
{
    string NumberAsString;
    cin >> NumberAsString;
    cout << StringToInteger(NumberAsString) << endl;
    return 0;
} 

3rd Method - but not for an individual conversion

std::string str4 = "453";
int i = 0, in=0; // 453 as on
for ( i = 0; i < str4.length(); i++)
{

    in = str4[i];
    cout <<in-48 ;

}

Here's my attempt, it doesn't follow your specs exactly though. Not fully tested, so be cautious.

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

=RIGHT(A1)  

is quite sufficient (where the string is contained in A1).

Similar in nature to LEFT, Excel's RIGHT function extracts a substring from a string starting from the right-most character:

SYNTAX

RIGHT( text, [number_of_characters] )

Parameters or Arguments

text

The string that you wish to extract from.

number_of_characters

Optional. It indicates the number of characters that you wish to extract starting from the right-most character. If this parameter is omitted, only 1 character is returned.

Applies To

Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000

Since number_of_characters is optional and defaults to 1 it is not required in this case.

However, there have been many issues with trailing spaces and if this is a risk for the last visible character (in general):

=RIGHT(TRIM(A1))  

might be preferred.

My 2 cents: i solved my OOM errors with bitmaps by:

a) scaling my images by a factor of 2

b) using Picasso library in my custom Adapter for a ListView, with a one-call in getView like this: Picasso.with(context).load(R.id.myImage).into(R.id.myImageView);

You must be providing the wrong path to the debug.keystore file.

Follow these steps to get the correct path and complete your command:

1. In eclipse, click the Window menu -> Preferences -> Expand Android -> Build
2. In the right panel, look for: Default debug keystore:
3. Select the entire box next to the label specified in Step 2

And finally, use the path you just copied from Step 3 to construct your command:

For example, in my case, it would be:

C:\Program Files\Java\jre7\bin>keytool -list -v -keystore "C:\Users\Siddharth Lele.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

UPDATED:

If you had already followed the steps mentioned above, the only other solution is to delete the debug.keystore and let Eclipse recreate it for you.

Step 1: Go to the path where your keystore is stored. In your case, C:\Users\Suresh\.android\debug.keystore

Step 2: Close and restart Eclipse.

Step 3 (Optional): You may need to clean your project before the debug.keystore is created again.

Source: http://www.coderanch.com/t/440920/Security/KeyTool-genkeypair-exception-Keystore-file

You can refer to this for the part about deleting your debug.keystore file: "Debug certificate expired" error in Eclipse Android plugins

Alternative approach if .htaccess customization is not ideal option:

I've created simple redirect server for public use. Just add A or CNAME record:

CNAME   r.simpleredirect.net
A       89.221.218.22

More info: https://simpleredirect.net

Of course... Almost all classes implements several interfaces. On any page of java documentation on Oracle you have a subsection named "All implemented interfaces".

Here an example of the Date class.

just need putting the datatype of the column in the datasource

dataSource: {
      data: empModel.Value,
      pageSize: 10,
      schema:  {
                model: {
                    fields: {
                        DOJ: { type: "date" }
                            }
                       }
               }  
           }

and then your statement column:

 columns: [
    {
        field: "Name",
        width: 90,
        title: "Name"
    },

    {
        field: "DOJ",
        width: 90,
        title: "DOJ",
        type: "date",
        format:"{0:MM-dd-yyyy}" 
    }
]

You forgot the table in your syntax:

drop table [table_name]

which drops a table.

Using

drop table if exists [table_name]

checks if the table exists before dropping it.
If it exists, it gets dropped.
If not, no error will be thrown and no action be taken.

For mac users, you can use Sequel Pro (free), which just provide the option to rename Databases. Though it doesn't delete the old DB.

once open the relevant DB just click: Database --> Rename database...

From GNU Make error appendix, as you see this is not a Make error but an error coming from gcc.

‘[foo] Error NN’ ‘[foo] signal description’ These errors are not really make errors at all. They mean that a program that make invoked as part of a recipe returned a non-0 error code (‘Error NN’), which make interprets as failure, or it exited in some other abnormal fashion (with a signal of some type). See Errors in Recipes. If no *** is attached to the message, then the subprocess failed but the rule in the makefile was prefixed with the - special character, so make ignored the error.

So in order to attack the problem, the error message from gcc is required. Paste the command in the Makefile directly to the command line and see what gcc says. For more details on Make errors click here.

NOTE: This is exactly what OP said they did. (But didn't show code for.) I show the details here, so that you can compare it to the accepted answer. My point is that OP's original instinct was, IMHO, better than the answer he accepted.

Given how highly upvoted the accepted answer is, I'd like to point out the "naive" answer to one-time initialization of static methods, is hardly more code than that implementation of Singleton -- and has an essential advantage.

final class MyClass  {
    public static function someMethod1() {
        MyClass::init();
        // whatever
    }

    public static function someMethod2() {
        MyClass::init();
        // whatever
    }


    private static $didInit = false;

    private static function init() {
        if (!self::$didInit) {
            self::$didInit = true;
            // one-time init code.
        }
    }

    // private, so can't create an instance.
    private function __construct() {
        // Nothing to do - there are no instances.
    }
}

The advantage of this approach, is that you get to call with the straightforward static function syntax:

MyClass::someMethod1();

Contrast it to the calls required by the accepted answer:

MyClass::getInstance->someMethod1();

As a general principle, it is best to pay the coding price once, when you code a class, to keep callers simpler.

If you are NOT using PHP 7.4's opcode.cache, then use Victor Nicollet's answer. Simple. No extra coding required. No "advanced" coding to understand. (I recommend including FrancescoMM's comment, to make sure "init" will never execute twice.) See Szczepan's explanation of why Victor's technique won't work with opcode.cache.

If you ARE using opcode.cache, then AFAIK my answer is as clean as you can get. The cost is simply adding the line MyClass::init(); at start of every public method. NOTE: If you want public properties, code them as a get / set pair of methods, so that you have a place to add that init call.

(Private members do NOT need that init call, as they are not reachable from the outside - so some public method has already been called, by the time execution reaches the private member.)

Actually the correct answer to this is to just add the schema to your document, like so

<packages xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">

...and you're done :)

If the XSD is not already cached and unavailable, you can add it as follows from the NuGet console

Install-Package NuGet.Manifest.Schema -Version 2.0.0

Once this is done, as noted in a comment below, you may want to move it from your current folder to the official schema folder that is found in

%VisualStudioPath%\Xml\Schemas

The numpy.where function is your friend. Because it's implemented to take full advantage of the array datatype, for large images you should notice a speed improvement over the pure python solution you provide.

Using numpy.where directly will yield a boolean mask indicating whether certain values match your conditions:

>>> data
array([[1, 8],
       [3, 4]])
>>> numpy.where( data > 3 )
(array([0, 1]), array([1, 1]))

And the mask can be used to index the array directly to get the actual values:

>>> data[ numpy.where( data > 3 ) ]
array([8, 4])

Exactly where you take it from there will depend on what form you'd like the results in.

Quick one-liner to convert UTF-8 characters into their 3-byte format:

var="$(echo -n '?' | od -An -tx1)"; printf '\\x%s' ${var^^}; echo

You can set the s bit for your script so that it does not need sudo and runs as root (and you do not need to write your root password in the script):

sudo chmod +s myscript

I will add one more "future-proof" reply

In ECMAScript 6, you can use the Spread syntax:

let arr1 = [0, 1, 2];_x000D_
let arr2 = [3, 4, 5];_x000D_
arr1.push(...arr2);_x000D_
_x000D_
console.log(arr1)

Spread syntax is not yet included in all major browsers. For the current compatibility, see this (continuously updated) compatibility table.

You can, however, use spread syntax with Babel.js.

edit:

See Jack Giffin's reply below for more comments on performance. It seems concat is still better and faster than spread operator.

To get the output of ls, use stdout=subprocess.PIPE.

>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo

The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.

>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.

subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().

>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout: 
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

Here is a filter that will take a date string OR javascript Date() object. It uses Moment.js and can apply any Moment.js transform function, such as the popular 'fromNow'

angular.module('myModule').filter('moment', function () {
  return function (input, momentFn /*, param1, param2, ...param n */) {
    var args = Array.prototype.slice.call(arguments, 2),
        momentObj = moment(input);
    return momentObj[momentFn].apply(momentObj, args);
  };
});

So...

{{ anyDateObjectOrString | moment: 'format': 'MMM DD, YYYY' }}

would display Nov 11, 2014

{{ anyDateObjectOrString | moment: 'fromNow' }}

would display 10 minutes ago

If you need to call multiple moment functions, you can chain them. This converts to UTC and then formats...

{{ someDate | moment: 'utc' | moment: 'format': 'MMM DD, YYYY' }}

Didn't quite see this variation in the answers yet. I had an additional constraint where I needed, given an initial seed, to select the same set of rows each time.

For MS SQL:

Minimum example:

select top 10 percent *
from table_name
order by rand(checksum(*))

Normalized execution time: 1.00

NewId() example:

select top 10 percent *
from table_name
order by newid()

Normalized execution time: 1.02

NewId() is insignificantly slower than rand(checksum(*)), so you may not want to use it against large record sets.

Selection with Initial Seed:

declare @seed int
set @seed = Year(getdate()) * month(getdate()) /* any other initial seed here */

select top 10 percent *
from table_name
order by rand(checksum(*) % seed) /* any other math function here */

If you need to select the same set given a seed, this seems to work.

Installed Chrome extension directories are listed below:

1. Copy the folder of the extension you wish to modify. ( Named according to the extension ID, to find the ID of the extension, go to chrome://extensions/). Once copied, you have to remove the _metadata folder.

2. From chrome://extensions in Developer mode select Load unpacked extension... and select your copied extension folder, if it contains a subfolder this is named by the version, select this version folder where there is a manifest file, this file is necessary for Chrome.

3. Make your changes, then select reload and refresh the page for your extension to see your changes.

I can't think of another way to compare values, but if you use the element of the set as the key, you can set the value to anything other than nil. Then you get fast lookups without having to search the entire table.

If you decide to use ggplot2, you can set transparency of overlapping points using the alpha argument.

e.g.

library(ggplot2)
ggplot(diamonds, aes(carat, price)) + geom_point(alpha = 1/40)

I used the Visual Studio 2008 Uninstall tool and it worked fine for me.

You can use this tool to uninstall Visual Studio 2008 official release and Visual Studio 2008 Release candidate (Only English version).

Found here, on the MSDN Forum: MSDN forum topic.

I found this answer here

Be sure you run the tool with admin-rights.

Others have given you the answer about appendChild.

Calling document.write() on a page that is not open (e.g. has finished loading) first calls document.open() which clears the entire content of the document (including the script calling document.write), so it's rarely a good idea to do that.

If you want to run the same command on multiple instances you can do this :

for i in c1 dm1 dm2 ds1 ds2 gtm_m gtm_sl; do docker exec -it $i /bin/bash -c "service sshd start"; done

As stated by Martijn Pieters, the correct, and fastest, format is:

if 1 in {x, y, z}:

Using his advice you would now have separate if-statements so that Python will read each statement whether the former were True or False. Such as:

if 0 in {x, y, z}:
    mylist.append("c")
if 1 in {x, y, z}:
    mylist.append("d")
if 2 in {x, y, z}:
    mylist.append("e")
...

This will work, but if you are comfortable using dictionaries (see what I did there), you can clean this up by making an initial dictionary mapping the numbers to the letters you want, then just using a for-loop:

num_to_letters = {0: "c", 1: "d", 2: "e", 3: "f"}
for number in num_to_letters:
    if number in {x, y, z}:
        mylist.append(num_to_letters[number])

Try executing this in your browser console or in a node.js repl.

var string = ' ';
string ? true : false;
//-> true

string = '';
string ? true : false;
//-> false

Therefore, a simple branching construct will suffice for the test.

if(string) {
    // string is not empty
}

you should use :

import unicodedata
from random import choice

import perfplot

    return u"".join([c for c in unicodedata.normalize('NFKD', x) if not unicodedata.combining(c)])


perfplot.show(
    setup=lambda n: ''.join([choice('Málaga François Phút Hon ??') for i in range(n)]),

You can use a CROSS JOIN:

SELECT *
FROM (  SELECT SUM(Fdays) AS fDaysSum 
        FROM tblFieldDays 
        WHERE tblFieldDays.NameCode=35 
        AND tblFieldDays.WeekEnding=1) A -- use you real query here
CROSS JOIN (SELECT SUM(CHdays) AS hrsSum 
            FROM tblChargeHours 
            WHERE tblChargeHours.NameCode=35 
            AND tblChargeHours.WeekEnding=1) B -- use you real query here

If you can already see the SQL being printed, that means you have the code below in your hibernate.cfg.xml:

<property name="show_sql">true</property>

To print the bind parameters as well, add the following to your log4j.properties file:

log4j.logger.net.sf.hibernate.type=debug

You can easily add a second legend by adding the line:

ax2.legend(loc=0)

You'll get this:

But if you want all labels on one legend then you should do something like this:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import rc
rc('mathtext', default='regular')

time = np.arange(10)
temp = np.random.random(10)*30
Swdown = np.random.random(10)*100-10
Rn = np.random.random(10)*100-10

fig = plt.figure()
ax = fig.add_subplot(111)

lns1 = ax.plot(time, Swdown, '-', label = 'Swdown')
lns2 = ax.plot(time, Rn, '-', label = 'Rn')
ax2 = ax.twinx()
lns3 = ax2.plot(time, temp, '-r', label = 'temp')

# added these three lines
lns = lns1+lns2+lns3
labs = [l.get_label() for l in lns]
ax.legend(lns, labs, loc=0)

ax.grid()
ax.set_xlabel("Time (h)")
ax.set_ylabel(r"Radiation ($MJ\,m^{-2}\,d^{-1}$)")
ax2.set_ylabel(r"Temperature ($^\circ$C)")
ax2.set_ylim(0, 35)
ax.set_ylim(-20,100)
plt.show()

Which will give you this:

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

I ran into the same problem. Placing a forward slash after the folder name worked for me.

ex: git add foldername/

The URI is encoded as UTF-8, but Tomcat is decoding them as ISO-8859-1. You need to edit the connector settings in the server.xml and add the URIEncoding="UTF-8" attribute.

or edit this parameter on your application.properties

server.tomcat.uri-encoding=utf-8

You seem to be specifying the form to use a HTTP 'GET' request using FormMethod.Get. This will not work unless you tell it to do a post as that is what you seem to want the ActionResult to do. This will probably work by changing FormMethod.Get to FormMethod.Post.

As well as this you may also want to think about how Get and Post requests work and how these interact with the Model.

It seems no one has mentioned a built-in factory method of producing ufunc in numpy package: np.frompyfunc which I have tested again np.vectorize and have outperformed it by about 20~30%. Of course it will perform well as prescribed C code or even numba(which I have not tested), but it can a better alternative than np.vectorize

f = lambda x, y: x * y
f_arr = np.frompyfunc(f, 2, 1)
vf = np.vectorize(f)
arr = np.linspace(0, 1, 10000)

%timeit f_arr(arr, arr) # 307ms
%timeit vf(arr, arr) # 450ms

I have also tested larger samples, and the improvement is proportional. See the documentation also here

You can set height and width like this also:

viewinstance.setLayoutParams(new LayoutParams(width, height));

• a standard
• human readable
• supported in editors like Sublime, VS Code, with syntax highlighting, formatting and section hide/show
• supports JPath so editors can report exactly which part of the object you have navigated to

• supports nested complex types within the object

Swift 3 Solution

Simple utility class

class ArchiveUtil {

    private static let PeopleKey = "PeopleKey"

    private static func archivePeople(people : [Human]) -> NSData {

        return NSKeyedArchiver.archivedData(withRootObject: people as NSArray) as NSData
    }

    static func loadPeople() -> [Human]? {

        if let unarchivedObject = UserDefaults.standard.object(forKey: PeopleKey) as? Data {

            return NSKeyedUnarchiver.unarchiveObject(with: unarchivedObject as Data) as? [Human]
        }

        return nil
    }

    static func savePeople(people : [Human]?) {

        let archivedObject = archivePeople(people: people!)
        UserDefaults.standard.set(archivedObject, forKey: PeopleKey)
        UserDefaults.standard.synchronize()
    }

}

Model Class

class Human: NSObject, NSCoding {

    var name:String?
    var age:Int?

    required init(n:String, a:Int) {

        name = n
        age = a
    }


    required init(coder aDecoder: NSCoder) {

        name = aDecoder.decodeObject(forKey: "name") as? String
        age = aDecoder.decodeInteger(forKey: "age")
    }


    public func encode(with aCoder: NSCoder) {

        aCoder.encode(name, forKey: "name")
        aCoder.encode(age, forKey: "age")

    }
}

How to call

var people = [Human]()

people.append(Human(n: "Sazzad", a: 21))
people.append(Human(n: "Hissain", a: 22))
people.append(Human(n: "Khan", a: 23))

ArchiveUtil.savePeople(people: people)

let others = ArchiveUtil.loadPeople()

for human in others! {

    print("name = \(human.name!), age = \(human.age!)")
}

You can use x = func()[0] to return the first value, x = func()[1] to return the second, and so on.

If you want to get multiple values at a time, use something like x, y = func()[2:4].

Please try this:

DELETE FROM `table` WHERE id >=163 and id<= 265

2 + 2 = 5(*)

(for some floating-precision values of 2)

This problem frequently arises when we think of"floating point" as a way to increase precision. Then we run afoul of the "floating" part, which means there is no guarantee of which numbers can be represented.

So while we might easily be able to represent "1.0, -1.0, 0.1, -0.1" as we get to larger numbers we start to see approximations - or we should, except we often hide them by truncating the numbers for display.

As a result, we might think the computer is storing "0.003" but it may instead be storing "0.0033333333334".

What happens if you perform "0.0003 - 0.0002"? We expect .0001, but the actual values being stored might be more like "0.00033" - "0.00029" which yields "0.000004", or the closest representable value, which might be 0, or it might be "0.000006".

With current floating point math operations, it is not guaranteed that (a / b) * b == a.

#include <stdio.h>

// defeat inline optimizations of 'a / b * b' to 'a'
extern double bodge(int base, int divisor) {
    return static_cast<double>(base) / static_cast<double>(divisor);
}

int main() {
    int errors = 0;
    for (int b = 1; b < 100; ++b) {
        for (int d = 1; d < 100; ++d) {
            // b / d * d ... should == b
            double res = bodge(b, d) * static_cast<double>(d);
            // but it doesn't always
            if (res != static_cast<double>(b))
                ++errors;
        }
    }
    printf("errors: %d\n", errors);
}

ideone reports 599 instances where (b * d) / d != b using just the 10,000 combinations of 1 <= b <= 100 and 1 <= d <= 100 .

The solution described in the FAQ is essentially to apply a granularity constraint - to test if (a == b +/- epsilon).

An alternative approach is to avoid the problem entirely by using fixed point precision or by using your desired granularity as the base unit for your storage. E.g. if you want times stored with nanosecond precision, use nanoseconds as your unit of storage.

C++11 introduced std::ratio as the basis for fixed-point conversions between different time units.

There is the semicolon missing (;) after the "50%"

but you should also notice that the percentage of your div is connected to the div that contains it.

for instance:

<div id="wrapper">
  <div class="container">
   adsf
  </div>
</div>

#wrapper {
  height:100px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

here the height of your .container will be 50px. it will be 50% of the 100px from the wrapper div.

if you have:

adsf

#wrapper {
  height:400px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

then you .container will be 200px. 50% of the wrapper.

So you may want to look at the divs "wrapping" your ".container"...

I think you just need;

List<string> list = new List<string>();
list.Add("hai");

There is a difference between

List<string> list; 

and

List<string> list = new List<string>();

When you didn't use new keyword in this case, your list didn't initialized. And when you try to add it hai, obviously you get an error.

I had run into this issue a while back, when I had two Bitbucket accounts and wanted to had to store separate SSH keys for both. This is what worked for me.

I created two separate ssh configurations as follows.

Host personal.bitbucket.org
    HostName bitbucket.org
    User git
    IdentityFile /Users/username/.ssh/personal
Host work.bitbucket.org
    HostName bitbucket.org
    User git
    IdentityFile /Users/username/.ssh/work

Now when I had to clone a repository from my work account - the command was as follows.

git clone [email protected]:teamname/project.git

I had to modify this command to:

git clone git@**work**.bitbucket.org:teamname/project.git

Similarly the clone command from my personal account had to be modified to

git clone git@personal.bitbucket.org:name/personalproject.git

Refer this link for more information.

Underscore.js has a nice method for that:

myArray = [{'id':'73','foo':'bar'},{'id':'45','foo':'bar'},etc.]
obj = _.find(myArray, function(obj) { return obj.id == '45' })

I have encountered this problem as well. Here is my solution:

In order to resolve this issue you need to do the following in the controller class:-

1. Change the import package from "import org.springframework.web.portlet.ModelAndView;" to "import org.springframework.web.servlet.ModelAndView;"...
2. Recompile and run the code... the problem should get resolved.

I will repost how I solved it here just for future references.

How I solved my similar problem

Prerequisite:

1. anaconda already installed
2. Spark already installed (https://spark.apache.org/downloads.html)
3. pyspark already installed (https://anaconda.org/conda-forge/pyspark)

Steps I did (NOTE: set the folder path accordingly to your system)

1. set the following environment variables.
2. SPARK_HOME to 'C:\spark\spark-3.0.1-bin-hadoop2.7'
3. set HADOOP_HOME to 'C:\spark\spark-3.0.1-bin-hadoop2.7'
4. set PYSPARK_DRIVER_PYTHON to 'jupyter'
5. set PYSPARK_DRIVER_PYTHON_OPTS to 'notebook'
6. add 'C:\spark\spark-3.0.1-bin-hadoop2.7\bin;' to PATH system variable.
7. Change the java installed folder directly under C: (Previously java was installed under Program files, so I re-installed directly under C:)
8. so my JAVA_HOME will become like this 'C:\java\jdk1.8.0_271'

now. it works !

Your best option here, is to use the Query String to 'send' the value.

how to get query string value using javascript

• So page 1 redirects to page2.html?someValue=ABC
• Page 2 can then read the query string and specifically the key 'someValue'

If this is anything more than a learning exercise you may want to consider the security implications of this though.

Global variables wont help you here as once the page is re-loaded they are destroyed.

Get all file item and filter them by suffix and then use PowerShell Excel VBA object to save the excel files to csv files.

$excelApp = New-Object -ComObject Excel.Application 
$excelApp.DisplayAlerts = $false 

$ExcelFiles | ForEach-Object { 
    $workbook = $excelApp.Workbooks.Open($_.FullName) 
    $csvFilePath = $_.FullName -replace "\.xlsx$", ".csv" 
    $workbook.SaveAs($csvFilePath, [Microsoft.Office.Interop.Excel.XlFileFormat]::xlCSV) 
    $workbook.Close() 
} 

You can find the complete sample here How to convert Excel xlsx file to csv file in batch by PowerShell

I tried t.boolean :active, :default => 1 in migration file for creating entire table. After ran that migration when i checked in db it made as null. Even though i told default as "1". After that slightly i changed migration file like this then it worked for me for setting default value on create table migration file.

t.boolean :active, :null => false,:default =>1. Worked for me.

The term "bootstrapping" usually applies to a situation where a system depends on itself to start, sort of a chicken and egg problem.

For instance:

• How do you compile a C compiler written in C?
• How do you start an OS initialization process if you don't have the OS running yet?
• How do you start a distributed (peer-to-peer) system where the clients depend on their currently known peers to find out about new peers in the system?

In that case, bootstrapping refers to a way of breaking the circular dependency, usually with the help of an external entity, e.g.

• You can use another C compiler to compile (bootstrap) your own compiler, and then you can use it to recompile itself
• You use a separate piece of code that sets up the initial process without depending on any functions provided by the OS
• You use a hard-coded list of initial peers or a hard-coded tracker URL that supplies the peer list

etc.

I was able to figure it out. In case someone wants to know below the code that worked for me:

ASCIIEncoding ascii = new ASCIIEncoding();
byte[] byteArray = Encoding.UTF8.GetBytes(sOriginal);
byte[] asciiArray = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, byteArray);
string finalString = ascii.GetString(asciiArray);

Let me know if there is a simpler way o doing it.

You can use eclipse to generate a runnable Jar : Export/Runable Jar file

You need to have the pointer to point somewhere to use it.

Try this code:

char word[64];
scanf("%s", word);

This creates a character array of lenth 64 and reads input to it. Note that if the input is longer than 64 bytes the word array overflows and your program becomes unreliable.

As Jens pointed out, it would be better to not use scanf for reading strings. This would be safe solution.

char word[64]
fgets(word, 63, stdin);
word[63] = 0;

Removing print statements can also fix the problem.

Apart from loading images, this error also happens when your code is printing continuously at a high rate, which is causing the error "IOPub data rate exceeded". E.g. if you have a print statement in a for loop somewhere that is being called over 1000 times.

Committing in git can be a multiple step process or one step depending on the situation.

1. This situation is where you have multiple file updated and wants to commit:

   You have to add all the modified files before you commit anything.

   git add -A
   

   or

   git add --all
   

2. After that you can use commit all the added files

   git commit
   

   with this you have to add the message for this commit.

For a Java Servlet environment, you can look at the Jawr library. The features page explains how it handles caching:

Jawr will try its best to force your clients to cache the resources. If a browser asks if a file changed, a 304 (not modified) header is sent back with no content. On the other hand, with Jawr you will be 100% sure that new versions of your bundles are downloaded by all clients. Every URL to your resources will include an automatically generated, content-based prefix that changes automatically whenever a resource is updated. Once you deploy a new version, the URL to the bundle will change as well so it will be impossible that a client uses an older, cached version.

The library also does JavaScript and CSS minification, but you can turn that off if you don't want it.

As of pandas v0.14.1, you can utilize select_dtypes() to select columns by dtype

In [2]: df = pd.DataFrame({'NAME': list('abcdef'),
    'On_Time': [True, False] * 3,
    'On_Budget': [False, True] * 3})

In [3]: df.select_dtypes(include=['bool'])
Out[3]:
  On_Budget On_Time
0     False    True
1      True   False
2     False    True
3      True   False
4     False    True
5      True   False

In [4]: mylist = list(df.select_dtypes(include=['bool']).columns)

In [5]: mylist
Out[5]: ['On_Budget', 'On_Time']

You should grab the standard input of the su process just launched and write down the command there, otherwise you are running the commands with the current UID.

Try something like this:

try{
    Process su = Runtime.getRuntime().exec("su");
    DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

    outputStream.writeBytes("screenrecord --time-limit 10 /sdcard/MyVideo.mp4\n");
    outputStream.flush();

    outputStream.writeBytes("exit\n");
    outputStream.flush();
    su.waitFor();
}catch(IOException e){
    throw new Exception(e);
}catch(InterruptedException e){
    throw new Exception(e);
}

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

array_map('trim', $data) would convert all subarrays into null. If it is needed to trim spaces only for strings and leave other types as it is, you can use:

$data = array_map(
    function ($item) {
        return is_string($item) ? trim($item) : $item;
    },
    $data
);

For me, this error was happening on localhost, but it disappeared when routing it through ngrok and was replaced with a MUCH more helpful error (net::ERR_INCOMPLETE_CHUNKED_ENCODING) that led me here:

https://stackoverflow.com/a/29969400

Basically, the Kestrel server I was using was saying it was chunked output, but not terminating it properly. I double checked it with Fiddler which confirmed the error.

Below is the relevant information from the link which Zaki provided.

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

If you just want to send an enum you can do something like:

First declare an enum containing some value(which can be passed through intent):

 public enum MyEnum {
    ENUM_ZERO(0),
    ENUM_ONE(1),
    ENUM_TWO(2),
    ENUM_THREE(3);
    private int intValue;

    MyEnum(int intValue) {
        this.intValue = intValue;
    }

    public int getIntValue() {
        return intValue;
    }

    public static MyEnum getEnumByValue(int intValue) {
        switch (intValue) {
            case 0:
                return ENUM_ZERO;
            case 1:
                return ENUM_ONE;
            case 2:
                return ENUM_TWO;
            case 3:
                return ENUM_THREE;
            default:
                return null;
        }
    }
}

Then:

  intent.putExtra("EnumValue", MyEnum.ENUM_THREE.getIntValue());

And when you want to get it:

  NotificationController.MyEnum myEnum = NotificationController.MyEnum.getEnumByValue(intent.getIntExtra("EnumValue",-1);

Piece of cake!

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.

Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Django 1.4.1

Python 2.7.3

#Model
class MonthEnd(models.Model):
    report = models.FileField(db_index=True, upload_to='not_used')

import csv
from os.path import join

#build and store the file
def write_csv():
    path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
    f = open(path, "w+b")

    #wipe the existing content
    f.truncate()

    csv_writer = csv.writer(f)
    csv_writer.writerow(('col1'))

    for num in range(3):
        csv_writer.writerow((num, ))

    month_end_file = MonthEnd()
    month_end_file.report.name = path
    month_end_file.save()

from my_app.models import MonthEnd

#serve it up as a download
def get_report(request):
    month_end = MonthEnd.objects.get(file_criteria=criteria)

    response = HttpResponse(month_end.report, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=report.csv'

    return response

var path = require("path");
var filepath = "C:\\Python27\\ArcGIS10.2\\python.exe";
var name = path.parse(filepath).name;
// returns
'python'

Above code returns the name of the file without extension, if you need the name with extention use

var path = require("path");
var filepath = "C:\\Python27\\ArcGIS10.2\\python.exe";
var name = path.basename(filepath);
// returns
'python.exe'

Very simple use of any

df <- <your structure>

df$Den <- apply(df,1,function(i) {ifelse(any(is.na(i)) | any(i != 1), 0, 1)})

This may also be because you might have given classname with all letters in lowercase something which groovy (know of version 2.5.0) does not support.

class name - User is accepted but user is not.

I've forgot to add the PostgreSQL JDBC Driver into my project (Mvnrepository).

Gradle:

// http://mvnrepository.com/artifact/postgresql/postgresql
compile group: 'postgresql', name: 'postgresql', version: '9.0-801.jdbc4'

Maven:

<dependency>
    <groupId>postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.0-801.jdbc4</version>
</dependency>

You can also download the JAR and import to your project manually.

PFX files are PKCS#12 Personal Information Exchange Syntax Standard bundles. They can include arbitrary number of private keys with accompanying X.509 certificates and a certificate authority chain (set certificates).

If you want to extract client certificates, you can use OpenSSL's PKCS12 tool.

openssl pkcs12 -in input.pfx -out mycerts.crt -nokeys -clcerts

The command above will output certificate(s) in PEM format. The ".crt" file extension is handled by both macOS and Window.

You mention ".cer" extension in the question which is conventionally used for the DER encoded files. A binary encoding. Try the ".crt" file first and if it's not accepted, easy to convert from PEM to DER:

openssl x509 -inform pem -in mycerts.crt -outform der -out mycerts.cer

If you need to remove white spaces at the end then here is a solution: https://www.geeksforgeeks.org/urlify-given-string-replace-spaces/

const stringQ1 = (string)=>{_x000D_
  //remove white space at the end _x000D_
  const arrString = string.split("")_x000D_
  for(let i = arrString.length -1 ; i>=0 ; i--){_x000D_
    let char = arrString[i];_x000D_
    _x000D_
    if(char.indexOf(" ") >=0){_x000D_
     arrString.splice(i,1)_x000D_
    }else{_x000D_
      break;_x000D_
    }_x000D_
  }_x000D_
_x000D_
  let start =0;_x000D_
  let end = arrString.length -1;_x000D_
  _x000D_
_x000D_
  //add %20_x000D_
  while(start < end){_x000D_
    if(arrString[start].indexOf(' ') >=0){_x000D_
      arrString[start] ="%20"_x000D_
      _x000D_
    }_x000D_
    _x000D_
    start++;_x000D_
  }_x000D_
  _x000D_
  return arrString.join('');_x000D_
}_x000D_
_x000D_
console.log(stringQ1("Mr John Smith   "))

Ok, maybe I'm missing something here, but this is the way I do it:

public static Byte[] ToByteArray(this Stream stream) {
    Int32 length = stream.Length > Int32.MaxValue ? Int32.MaxValue : Convert.ToInt32(stream.Length);
    Byte[] buffer = new Byte[length];
    stream.Read(buffer, 0, length);
    return buffer;
}

rbind() needs the two object names to be the same. For example, the first object names: ID Age, the next object names: ID Gender,if you want to use rbind(), it will print out:

names do not match previous names

I'm not quite sure if I'm allowed to answer a question that was asked like 2 years ago as this is my first answer on stackoverflow but, here's my solution;

If you once retrieved the date from your MySQL database, split it and then use the splitted values.

$(document).ready(function () {
    var datefrommysql = $('.date-from-mysql').attr("date");
    var arraydate = datefrommysql.split('.');
    var yearfirstdigit = arraydate[2][2];
    var yearlastdigit = arraydate[2][3];
    var day = arraydate[0];
    var month = arraydate[1];
    $('.formatted-date').text(day + "/" + month + "/" + yearfirstdigit + yearlastdigit);
});

Here's a fiddle.

How about this?

select DATEPART(MM,'january 01 2011') -- returns 1
select DATEPART(MM,'march 01 2011')  -- returns 3
select DATEPART(MM,'august 01 2011') -- returns 8

If those are the only changes, you can simply do

git commit -a

to commit all changes. That will include deleted files.

It can also be achieved by:

jest --findRelatedTests path/to/fileA.js

Reference (Jest CLI Options)

How can that be achieved in the Nx monorepo? Here is the answer (in directory /path/to/workspace):

npx nx test api --findRelatedTests=apps/api/src/app/mytest.spec.ts

Another way would be to use lftp:

lftp sftp://user:password@host  -e "put local-file.name; bye"

The disadvantage of this method is that other users on the computer can read the password from tools like ps and that the password can become part of your shell history.

A more secure alternative which is available since LFTP 4.5.0 is setting the LFTP_PASSWORDenvironment variable and executing lftp with --env-password. Here's a full example:

LFTP_PASSWORD="just_an_example"
lftp --env-password sftp://user@host  -e "put local-file.name; bye"

LFTP also includes a cool mirroring feature (can include delete after confirmed transfer --Remove-source-files):

lftp -e 'mirror -R /local/log/path/ /remote/path/' --env-password -u user sftp.foo.com

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

How to copy selected files from Android with adb pull

You can replace '<' with < and '>' with >. For example:

echo "<div>";

The output will be visible <div>.

For longer strings, make a function, for example

function example($input) {
    $output = str_replace('>', '&gt;', str_replace('<', '&lt;', $html));
    return $output;
}

echo example($your_html);

Don't forget to put backslashes href=\"#\" or do it with single quotes href='#' or change it in a function too with str_replace.

I found out that single quote > double quote > wrapped in ampersands did work. So, for me it looks like this:

=QUERY('Youth Conference Registration'!C:Y,"select C where Y = '"&A1&"'", 0)

You can use arg(), as follow:

double dbl = 0.25874601;
QString str = QString("%1").arg(dbl);

This overcomes the problem of: "Fixed precision" at the other functions like: setNum() and number(), which will generate random numbers to complete the defined precision

If you want to have a simple Line in your Layout to separate two views you can use a generic View with the height and width you want the line to have and a set background color.

With this approach you don't need to override a View or use a Canvas yourself just simple and clean add the line in xml.

<View
 android:layout_width="match_parent"
 android:layout_height="1dp"
 android:background="@android:color/black" />

The example code I provided will generate a line that fills the screen in width and has a height of one dp.

If you have problems with the drawing of the line on small screens consider to change the height of the line to px. The problem is that on a ldpi screen the line will be 0.75 pixel high. Sometimes this may result in a rounding that makes the line vanish. If this is a problem for your layout define the width of the line a ressource file and create a separate ressource file for small screens that sets the value to 1px instead of 1dp.

This approach is only usable if you want horizontal or vertical lines that are used to divide layout elements. If you want to achieve something like a cross that is drawn into an image my approach will not work.

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

Use chr (13) for carriage return and chr (10) for new line

echo $clientid;
echo ' ';
echo $lastname;
echo ' ';
echo chr (13). chr (10);

The first part of your question (how to get the bytes) was already answered by others: look in the System.Text.Encoding namespace.

I will address your follow-up question: why do you need to pick an encoding? Why can't you get that from the string class itself?

The answer is in two parts.

First of all, the bytes used internally by the string class don't matter, and whenever you assume they do you're likely introducing a bug.

If your program is entirely within the .Net world then you don't need to worry about getting byte arrays for strings at all, even if you're sending data across a network. Instead, use .Net Serialization to worry about transmitting the data. You don't worry about the actual bytes any more: the Serialization formatter does it for you.

On the other hand, what if you are sending these bytes somewhere that you can't guarantee will pull in data from a .Net serialized stream? In this case you definitely do need to worry about encoding, because obviously this external system cares. So again, the internal bytes used by the string don't matter: you need to pick an encoding so you can be explicit about this encoding on the receiving end, even if it's the same encoding used internally by .Net.

I understand that in this case you might prefer to use the actual bytes stored by the string variable in memory where possible, with the idea that it might save some work creating your byte stream. However, I put it to you it's just not important compared to making sure that your output is understood at the other end, and to guarantee that you must be explicit with your encoding. Additionally, if you really want to match your internal bytes, you can already just choose the Unicode encoding, and get that performance savings.

Which brings me to the second part... picking the Unicode encoding is telling .Net to use the underlying bytes. You do need to pick this encoding, because when some new-fangled Unicode-Plus comes out the .Net runtime needs to be free to use this newer, better encoding model without breaking your program. But, for the moment (and forseeable future), just choosing the Unicode encoding gives you what you want.

It's also important to understand your string has to be re-written to wire, and that involves at least some translation of the bit-pattern even when you use a matching encoding. The computer needs to account for things like Big vs Little Endian, network byte order, packetization, session information, etc.

With heirloom-mailx you can change sendmail program to your hook script, replace headers there and then use sendmail.

The script I use (~/bin/sendmail-hook):

#!/bin/bash

sed '1,/^$/{
s,^\(Content-Type: \).*$,\1text/html; charset=utf-8,g
s,^\(Content-Transfer-Encoding: \).*$,\18bit,g
}' | sendmail $@

This script changes the values in the mail header as follows:

• Content-Type: to text/html; charset=utf-8
• Content-Transfer-Encoding: to 8bit (not sure if this is really needed).

To send HTML email:

mail -Ssendmail='~/bin/sendmail-hook' \
    -s "Built notification" [email protected] < /var/www/report.csv

This error message means you failed to authenticate.

These are common reasons that can cause that:

1. Trying to connect with the wrong key. Are you sure this instance is using this keypair?
2. Trying to connect with the wrong username. ubuntu is the username for the ubuntu based AWS distribution, but on some others it's ec2-user (or admin on some Debians, according to Bogdan Kulbida's answer)(can also be root, fedora, see below)
3. Trying to connect the wrong host. Is that the right host you are trying to log in to?

Note that 1. will also happen if you have messed up the /home/<username>/.ssh/authorized_keys file on your EC2 instance.

About 2., the information about which username you should use is often lacking from the AMI Image description. But you can find some in AWS EC2 documentation, bullet point 4. : http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AccessingInstancesLinux.html

Use the ssh command to connect to the instance. You'll specify the private key (.pem) file and user_name@public_dns_name. For Amazon Linux, the user name is ec2-user. For RHEL5, the user name is either root or ec2-user. For Ubuntu, the user name is ubuntu. For Fedora, the user name is either fedora or ec2-user. For SUSE Linux, the user name is root. Otherwise, if ec2-user and root don't work, check with your AMI provider.

Finally, be aware that there are many other reasons why authentication would fail. SSH is usually pretty explicit about what went wrong if you care to add the -v option to your SSH command and read the output, as explained in many other answers to this question.

I eventually used:

weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)

It worked just fine, except that I got the following message.

C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated.  Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.

Hope this helps.

I would add some checks after the copy (using '||') but i'm not sure how "copy /v" reacts when it encounters an error.

you may want to try this:

copy /V "%%f" "%dTarget%\" 2>nul|| echo En error occured copying "%%F".&& exit /b 1

As the copy line. let me know if you get something out of it (in no position to test a copy failure atm..)

Setting tintColor for UITextField and UITextView works differently. While for UITextField you don't need to call additional code after updating tintColor to change cursor color, but for UITextView you need.

So after setting tintColor for UITextView (it doesn't matter in IB or in code) you need to call textView.tintColorDidChange() in order to apply it (actually it will pass text view's config down to its subviews hierarchy).

As long as you override equals() on each key and value contained in the map, then m1.equals(m2) should be reliable to check for maps equality.

The same result can be obtained also by comparing toString() of each map as you suggested, but using equals() is a more intuitive approach.

May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals(). More details about this see here.

I tried to update the user, and it worked. See the command below.

USE ComparisonData// databaseName
EXEC  sp_change_users_login @Action='update_one', @UserNamePattern='ftool',@LoginName='ftool';

Just replace user('ftool') accordingly.

>>> x = 'foo'
>>> x
'foo'

So the name x is attached to 'foo' string. When you call for example repr(x) the interpreter puts 'foo' instead of x and then calls repr('foo').

>>> repr(x)
"'foo'"
>>> x.__repr__()
"'foo'"

repr actually calls a magic method __repr__ of x, which gives the string containing the representation of the value 'foo' assigned to x. So it returns 'foo' inside the string "" resulting in "'foo'". The idea of repr is to give a string which contains a series of symbols which we can type in the interpreter and get the same value which was sent as an argument to repr.

>>> eval("'foo'")
'foo'

When we call eval("'foo'"), it's the same as we type 'foo' in the interpreter. It's as we directly type the contents of the outer string "" in the interpreter.

>>> eval('foo')

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    eval('foo')
  File "<string>", line 1, in <module>
NameError: name 'foo' is not defined

If we call eval('foo'), it's the same as we type foo in the interpreter. But there is no foo variable available and an exception is raised.

>>> str(x)
'foo'
>>> x.__str__()
'foo'
>>> 

str is just the string representation of the object (remember, x variable refers to 'foo'), so this function returns string.

>>> str(5)
'5'

String representation of integer 5 is '5'.

>>> str('foo')
'foo'

And string representation of string 'foo' is the same string 'foo'.

New introduction 2

In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:

Set FolderTgt = CreateObject("Outlook.Application"). _
              GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)

I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.

This macro, outputs the name of the store holding the default Inbox to the Immediate Window:

Sub DsplUsernameOfDefaultStore()

  Dim NS As Outlook.NameSpace
  Dim DefaultInboxFldr As MAPIFolder

  Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
  Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)

  Debug.Print DefaultInboxFldr.Parent.Name

End Sub

On my installation, this outputs: "Outlook Data File".

I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.

New introduction 1

A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.

The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)

Original text

There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.

For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.

What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.

The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.

The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:

Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.

All other comments containing hashes suggest amendments to adapt the macro to your requirements.

How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed".

The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.

This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:

Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on

Extracting the values from the original of this string should not be difficult.

I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.

Good luck.

If you declare a DateTime, then the default value is DateTime.MinValue, and hence you have to check it like this:

DateTime dat = new DateTime();

 if (dat==DateTime.MinValue)
 {
     //unassigned
 }

If the DateTime is nullable, well that's a different story:

 DateTime? dat = null;

 if (!dat.HasValue)
 {
     //unassigned
 }

EntityFunctions is obsolete. Consider using DbFunctions instead.

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
   .Where(x => DbFunctions.TruncateTime(x.DateTimeStart) == currentDate.Date);

just run git log origin/$BRANCH_NAME

Just for the sake of completeness, appending values to a vector in a for loop is not really the philosophy in R. R works better by operating on vectors as a whole, as @BrodieG pointed out. See if your code can't be rewritten as:

ouput <- sapply(values, function(v) return(2*v))

Output will be a vector of return values. You can also use lapply if values is a list instead of a vector.

A contract is: If two objects are equal then they should have the same hashcode and if two objects are not equal then they may or may not have same hash code.

Try using your object as key in HashMap (edited after comment from joachim-sauer), and you will start facing trouble. A contract is a guideline, not something forced upon you.

Although the other answers are quite helpful, just wanted to share my experience as well.

I faced the issue when I had deleted a table whose id was already being referenced as foreign key in other tables (with data) and tried to recreate/import the table with some additional columns.

The query for recreation (generated in phpMyAdmin) looked like the following:

CREATE TABLE `the_table` (
  `id` int(11) NOT NULL,            /* No PRIMARY KEY index */  
  `name` varchar(255) NOT NULL,
  `name_fa` varchar(255) NOT NULL,
  `name_pa` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

... /* SOME DATA DUMP OPERATION */

ALTER TABLE `the_table`
  ADD PRIMARY KEY (`id`), /* PRIMARY KEY INDEX */
  ADD UNIQUE KEY `uk_acu_donor_name` (`name`);

As you may notice, the PRIMARY KEY index was set after the creation (and insertion of data) which was causing the problem.

Solution

The solution was to add the PRIMARY KEY index on table definition query for the id which was being referenced as foreign key, while also removing it from the ALTER TABLE part where indexes were being set:

CREATE TABLE `the_table` (
  `id` int(11) NOT NULL PRIMARY KEY,            /* <<== PRIMARY KEY INDEX ON CREATION */  
  `name` varchar(255) NOT NULL,
  `name_fa` varchar(255) NOT NULL,
  `name_pa` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Try this:

// Substitute appropriate type.
ArrayList<...> a = new ArrayList<...>();

// Add elements to list.

// Generate an iterator. Start just after the last element.
ListIterator li = a.listIterator(a.size());

// Iterate in reverse.
while(li.hasPrevious()) {
  System.out.println(li.previous());
}

Here you go:

$(document).ready(function(){
    $('#submenu li').hover(function(){
        $('#carousel').css('background-position', '10px 10px');
    }, function(){
        $('#carousel').css('background-position', '');
    });
});

One other difference lies in the performance.

As the DLL is loaded at runtime by the .exe(s), the .exe(s) and the DLL work with shared memory concept and hence the performance is low relatively to static linking.

On the other hand, a .lib is code that is linked statically at compile time into every process that requests. Hence the .exe(s) will have single memory, thus increasing the performance of the process.

You could use a placeholder because it does it for you, but for old browsers that don't support placeholder, try this:

<script>
function clearThis(target) {
    if (target.value == "[email protected]") {
        target.value = "";
    }
}
function replace(target) {
    if (target.value == "" || target.value == null) {
        target.value == "[email protected]";
    }
}
</script>
<input type="text" name="email" value="[email protected]" size="x" onfocus="clearThis(this)" onblur="replace(this)" />

CODE EXPLAINED: When the text box has focus, clear the value. When text box is not focused AND when the box is blank, replace the value.

I hope that works, I have been having the same issue, but then I tried this and it worked for me.

document.getElementById('Id').value='new value';

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById

if let htmlFile = NSBundle.mainBundle().pathForResource("aa", ofType: "html"){
    do{
        let htmlString = try NSString(contentsOfFile: htmlFile, encoding:NSUTF8StringEncoding )
        webView.loadHTMLString(htmlString as String, baseURL: nil)
    }
    catch _ {
    }
}

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

Anaconda has not updated python internally to 3.6.

a) Method 1

1. If you wanted to update you will type conda update python
2. To update anaconda type conda update anaconda

3. If you want to upgrade between major python version like 3.5 to 3.6, you'll have to do

   conda install python=$pythonversion$
   

b) Method 2 - Create a new environment (Better Method)

conda create --name py36 python=3.6

c) To get the absolute latest python(3.6.5 at time of writing)

conda create --name py365 python=3.6.5 --channel conda-forge

You can see all this from here

Also, refer to this for force upgrading

EDIT: Anaconda now has a Python 3.6 version here

This might not be a perfect solution yet (and it’s with jQuery) but maybe it’s a direction / concept to work on: what about doing it the other way round? Which means deactivating the :hover css states by default and activate them if a mousemove event is detected anywhere on the document. Of course this does not work if someone deactivated js. What else might speak against doing it this way round?

Maybe like this:

CSS:

/* will only work if html has class "mousedetected" */
html.mousedetected a:hover {
   color:blue;
   border-color:green;
}

jQuery:

/* adds "mousedetected" class to html element if mouse moves (which should never happen on touch-only devices shouldn’t it?) */
$("body").mousemove( function() {
    $("html").addClass("mousedetected");
});

Use the quotemeta function:

$text_to_search = "example text with [foo] and more";
$search_string = quotemeta "[foo]";

print "wee" if ($text_to_search =~ /$search_string/);

The hex values are on the mainpage of http://glyphicons.com/ in the tooltips of the specific icon.

None of these will allow you to compile PHP with cURL enabled.

In order to compile with cURL, you need libcurl header files (.h files). They are usually found in /usr/include/curl. They generally are bundled in a separate development package.

Per example, to install libcurl in Ubuntu:

sudo apt-get install libcurl4-gnutls-dev

Or CentOS:

sudo yum install curl-devel

Then you can just do:

./configure --with-curl # other options...

If you compile cURL manually, you can specify the path to the files without the lib or include suffix. (e.g.: /usr/local if cURL headers are in /usr/local/include/curl).

You can do this by changing the gradle file.

 build.gradle > change
    dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    }
    gradle-wrapper.properties > update
    distributionUrl=https://services.gradle.org/distributions/gradle-4.6-all.zip

If you are using Guava, you can use Files.move(from, to)

from os import listdir

def find_csv_filenames( path_to_dir, suffix=".csv" ):
    filenames = listdir(path_to_dir)
    return [ filename for filename in filenames if filename.endswith( suffix ) ]

The function find_csv_filenames() returns a list of filenames as strings, that reside in the directory path_to_dir with the given suffix (by default, ".csv").

Addendum

How to print the filenames:

filenames = find_csv_filenames("my/directory")
for name in filenames:
  print name

The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it.

Try this:

void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;

And then when you invoke it, you need an object of type MyClass to do so, for example this:

(this->*func)(<argument>);

http://www.codeguru.com/cpp/cpp/article.php/c17401/C-Tutorial-PointertoMember-Function.htm

This should work:

git status

This will show what is not staged and what is staged.

php7.1 mongoDB:
$data = $collection->findOne([],['sort' => ['_id' => -1],'projection' => ['_id' => 1]]);

Assuming that you made the necessary changes in your php.ini files:

You can resolve the issue by adding the following line in your nginx.conf file found in the following path:

/etc/nginx/nginx.conf

then edit the file using vim text editor as follows:

vi /etc/nginx/nginx.conf

and add client_max_body_size with a large enough value, for example:

client_max_body_size 20MB;

After that make sure you save using :xi or :wq

And then restart your nginx.

That's it.

Worked for me, hope this helps.

SSIS Integration with Visual Studio 2017 available from Aug 2017.

SSIS designer is now available for Visual Studio 2017! ARCHIVE

I installed in July 2018 and appears working fine. See Download link

I experienced the same problem while trying to write a code concerning Speech_to_Text.

The solution was very simple. Uninstall the previous pywin32 using the pip method

pip uninstall pywin32

The above will remove the existing one which is by default for 32 bit computers. And install it again using

pip install pywin32

This will install the one for the 64 bit computer which you are using.

I think this should work:

#include <time.h>

clock_t start = clock(), diff;
ProcessIntenseFunction();
diff = clock() - start;

int msec = diff * 1000 / CLOCKS_PER_SEC;
printf("Time taken %d seconds %d milliseconds", msec/1000, msec%1000);

For other future users who do not want to make their controllers asynchronous, or cannot access the HttpContext, or are using dotnet core (this answer is the first I found on Google trying to do this), the following worked for me:

[HttpPut("{pathId}/{subPathId}"),
public IActionResult Put(int pathId, int subPathId, [FromBody] myViewModel viewModel)
{

    var body = new StreamReader(Request.Body);
    //The modelbinder has already read the stream and need to reset the stream index
    body.BaseStream.Seek(0, SeekOrigin.Begin); 
    var requestBody = body.ReadToEnd();
    //etc, we use this for an audit trail
}

There is a new tool called GitHub HTML Preview, which does exactly what you want. Just prepend http://htmlpreview.github.com/? to the URL of any HTML file, e.g. http://htmlpreview.github.com/?https://github.com/twbs/bootstrap/blob/gh-pages/2.3.2/index.html

Note: This tool is actually a github.io page and is not affiliated with github as a company.

My preferred method:

if (*ptr == 0) // empty string

Probably more common:

if (strlen(ptr) == 0) // empty string

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

My solution

• Assuming that form id = "my_form_id"
• It detects the form method and form action from HTML

jQuery code

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});

Here is how I solved the issue, might be useful to some:

Ajax modal doesn't seem to be available with boostrap 2.1.1

So I ended up coding it myself:

$('[data-toggle="modal"]').click(function(e) {
  e.preventDefault();
  var url = $(this).attr('href');
  //var modal_id = $(this).attr('data-target');
  $.get(url, function(data) {
      $(data).modal();
  });
});

Example of a link that calls a modal:

<a href="{{ path('ajax_get_messages', { 'superCategoryID': 6, 'sex': sex }) }}" data-toggle="modal">
    <img src="{{ asset('bundles/yopyourownpoet/images/messageCategories/BirthdaysAnniversaries.png') }}" alt="Birthdays" height="120" width="109"/>
</a>

I now send the whole modal markup through ajax.

Found the solution to the problem.

When you click on a thickbox link that open a iframe, it insert an iframe with an id of TB_iframeContent.

Instead of relying on the $(document).ready event in the iframe code, I just have to bind to the load event of the iframe in the parent document:

$('#TB_iframeContent', top.document).load(ApplyGalleria);

This code is in the iframe but binds to an event of a control in the parent document. It works in FireFox and IE.

tablename$column3=rowSums(cbind(tablename$column1,tablename$column2),na.rm=TRUE)

This can be used to ignore blank values in the excel sheet.
I have used for Euro stat dataset.

This example works in R:

crime_stat_data$All_theft <-rowSums(cbind(crime_stat_data$Theft,crime_stat_data$Theft_of_a_motorised_land_vehicle, crime_stat_data$Burglary, crime_stat_data$Burglary_of_private_residential_premises), na.rm=TRUE)  

I was hitting this issue while running Tomcat inside of a Docker container. To fix this make sure you add the '-p 8000:8000' argument in your docker run command to expose this port to your local machine. You will of course need the setenv.sh file in your ${CATALINA_HOME}/bin/ within your container as well.

No - the object approach is JavaScript's answer to this. There is no problem with this provided your function expects an object rather than separate params.

n=int(input())
pair = dict()

for i in range(0,n):
        word = input().split()
        key = word[0]
        value = word[1]
        pair[key]=value

print(pair)

In case you want to be fully bomb prove, this is what I would advice:

@('Apples', 'Apples ', 'APPLES', 'Banana') | 
    Sort-Object -Property @{Expression={$_.Trim()}} -Unique

Output:

Apples
Banana

This uses the Property parameter to first Trim() the strings, so extra spaces are removed and then selects only the -Unique values.

More info on Sort-Object:

Get-Help Sort-Object -ShowWindow

New ways I: fetch

TL;DR I'd recommend this way as long as you don't have to send synchronous requests or support old browsers.

A long as your request is asynchronous you can use the Fetch API to send HTTP requests. The fetch API works with promises, which is a nice way to handle asynchronous workflows in JavaScript. With this approach you use fetch() to send a request and ResponseBody.json() to parse the response:

fetch(url)
  .then(function(response) {
    return response.json();
  })
  .then(function(jsonResponse) {
    // do something with jsonResponse
  });

Compatibility: The Fetch API is not supported by IE11 as well as Edge 12 & 13. However, there are polyfills.

New ways II: responseType

As Londeren has written in his answer, newer browsers allow you to use the responseType property to define the expected format of the response. The parsed response data can then be accessed via the response property:

var req = new XMLHttpRequest();
req.responseType = 'json';
req.open('GET', url, true);
req.onload  = function() {
   var jsonResponse = req.response;
   // do something with jsonResponse
};
req.send(null);

Compatibility: responseType = 'json' is not supported by IE11.

The classic way

The standard XMLHttpRequest has no responseJSON property, just responseText and responseXML. As long as bitly really responds with some JSON to your request, responseText should contain the JSON code as text, so all you've got to do is to parse it with JSON.parse():

var req = new XMLHttpRequest();
req.overrideMimeType("application/json");
req.open('GET', url, true);
req.onload  = function() {
   var jsonResponse = JSON.parse(req.responseText);
   // do something with jsonResponse
};
req.send(null);

Compatibility: This approach should work with any browser that supports XMLHttpRequest and JSON.

JSONHttpRequest

If you prefer to use responseJSON, but want a more lightweight solution than JQuery, you might want to check out my JSONHttpRequest. It works exactly like a normal XMLHttpRequest, but also provides the responseJSON property. All you have to change in your code would be the first line:

var req = new JSONHttpRequest();

JSONHttpRequest also provides functionality to easily send JavaScript objects as JSON. More details and the code can be found here: http://pixelsvsbytes.com/2011/12/teach-your-xmlhttprequest-some-json/.

Full disclosure: I'm the owner of Pixels|Bytes. I thought that my script was a good solution for the original question, but it is rather outdated today. I do not recommend to use it anymore.

If you want to cut out the last or the first do this:

list = ["This", "is", "a", "list"]
listnolast = list[:-1]
listnofirst = list[1:]

If you change 1 to 2 the first 2 characters will be removed not the second. Hope this still helps!

With Git 2.22 (Q2 2019), you will have a simpler approach: git branch --show-current.

See commit 0ecb1fc (25 Oct 2018) by Daniels Umanovskis (umanovskis).
^{(Merged by Junio C Hamano -- gitster -- in commit 3710f60, 07 Mar 2019)}

branch: introduce --show-current display option

When called with --show-current, git branch will print the current branch name and terminate.
Only the actual name gets printed, without refs/heads.
In detached HEAD state, nothing is output.

Intended both for scripting and interactive/informative use.
Unlike git branch --list, no filtering is needed to just get the branch name.

See the original discussion on the Git mailing list in Oct. 2018, and the actual pathc.

I like Ibu's one but, I think I have a better solution using his idea.

//Fade In.
element.style.opacity = 0;
var Op1 = 0;
var Op2 = 1;
var foo1, foo2;
foo1 = setInterval(Timer1, 20);
function Timer1()
{
    element.style.opacity = Op1;
    Op1 = Op1 + .01;
    console.log(Op1); //Option, but I recommend it for testing purposes.
    if (Op1 > 1)
    {
        clearInterval(foo1);
        foo2 = setInterval(Timer3, 20);
    }
}

This solution uses a additional equation unlike Ibu's solution, which used a multiplicative equation. The way it works is it takes a time increment (t), an opacity increment (o), and a opacity limit (l) in the equation, which is: (T = time of fade in miliseconds) [T = (l/o)*t]. the "20" represents the time increments or intervals (t), the ".01" represents the opacity increments (o), and the 1 represents the opacity limit (l). When you plug the numbers in the equation you get 2000 milliseconds (or 2 seconds). Here is the console log:

Notice how the opacity follows the opacity increment amount of .01 just like in the code. If you use the code Ibu made,

//I made slight edits but keeped the ESSENTIAL stuff in it.
var op = 0.01;  // initial opacity
var timer = setInterval(function () {
    if (op >= 1){
        clearInterval(timer);
    }
    element.style.opacity = op;
    op += op * 0.1;
}, 20);

you will get these numbers (or something similar) in you console log. Here is what I got.

Notice that there is no discernible pattern. If you ran Ibu's code, you would never know how long the fade was. You would have to grab a timer and guess and check 2 seconds. Nonetheless, Ibu's code did make a pretty nice fade in (it probably works for fade out. I don't know because I didn't use a fade out yet). My code will also work for a fade out. Let's just say you wanted 2 seconds for a fade out. You can do that with my code. Here is how it would look:

//Fade out. (Continued from the fade in.
function Timer2()
{
    element.style.opacity = Op2;
    Op2 = Op2 - .01;
    console.log(Op2); //Option, but I recommend it for testing purposes.
    if (Op2 < 0)
    { 
        clearInterval(foo2);
    }
}

All I did was change the opacity to 1 (or fully opaque). I changed the opacity increment to -.01 so it would start turning invisible. Lastly, I changed the opacity limit to 0. When it hits the opacity limit, the timer will stop. Same as the last one, except it used 1 instead of 0. When you run the code, here is what the console log should relatively look like.

As you can see, the .01 pattern still exists in the fade out. Both fades are smooth and precise. I hope these codes helped you or gave you insight on the topic. If you have any additions or suggestions let me know. Thank you for taking the time to view this!

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

You may try below code...

$(document).ready(function(){_x000D_
    $('form').find('input[type=text],textarea,select').filter(':visible:first').focus();_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>_x000D_
<form>_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
    _x000D_
<input type="submit" />_x000D_
</form>

Set up a System variable from Maven and in java use following call

System.getProperty("Key");

Take a look at Phil Haack's post on model binding JSON data. The problem is that the default model binder doesn't serialize JSON properly. You need some sort of ValueProvider OR you could write a custom model binder:

using System.IO;
using System.Web.Script.Serialization;

public class JsonModelBinder : DefaultModelBinder {
        public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) {
            if(!IsJSONRequest(controllerContext)) {
                return base.BindModel(controllerContext, bindingContext);
            }

            // Get the JSON data that's been posted
            var request = controllerContext.HttpContext.Request;
            //in some setups there is something that already reads the input stream if content type = 'application/json', so seek to the begining
            request.InputStream.Seek(0, SeekOrigin.Begin);
            var jsonStringData = new StreamReader(request.InputStream).ReadToEnd();

            // Use the built-in serializer to do the work for us
            return new JavaScriptSerializer()
                .Deserialize(jsonStringData, bindingContext.ModelMetadata.ModelType);

            // -- REQUIRES .NET4
            // If you want to use the .NET4 version of this, change the target framework and uncomment the line below
            // and comment out the above return statement
            //return new JavaScriptSerializer().Deserialize(jsonStringData, bindingContext.ModelMetadata.ModelType);
        }

        private static bool IsJSONRequest(ControllerContext controllerContext) {
            var contentType = controllerContext.HttpContext.Request.ContentType;
            return contentType.Contains("application/json");
        }
    }

public static class JavaScriptSerializerExt {
        public static object Deserialize(this JavaScriptSerializer serializer, string input, Type objType) {
            var deserializerMethod = serializer.GetType().GetMethod("Deserialize", BindingFlags.NonPublic | BindingFlags.Static);

            // internal static method to do the work for us
            //Deserialize(this, input, null, this.RecursionLimit);

            return deserializerMethod.Invoke(serializer,
                new object[] { serializer, input, objType, serializer.RecursionLimit });
        }
    }

And tell MVC to use it in your Global.asax file:

ModelBinders.Binders.DefaultBinder = new JsonModelBinder();

Also, this code makes use of the content type = 'application/json' so make sure you set that in jquery like so:

$.ajax({
    dataType: "json",
    contentType: "application/json",            
    type: 'POST',
    url: '/Controller/Action',
    data: { 'items': JSON.stringify(lineItems), 'id': documentId }
});

Building on @Pvl's answer, you can include type safety on your returned value as well if you use overrides:

function dig<
  T,
  K1 extends keyof T
  >(obj: T, key1: K1): T[K1];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1]
  >(obj: T, key1: K1, key2: K2): T[K1][K2];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2]
  >(obj: T, key1: K1, key2: K2, key3: K3): T[K1][K2][K3];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2],
  K4 extends keyof T[K1][K2][K3]
  >(obj: T, key1: K1, key2: K2, key3: K3, key4: K4): T[K1][K2][K3][K4];

function dig<
  T,
  K1 extends keyof T,

    let value: any = obj && obj[key1];

    if (key2) {
      value = value && value[key2];
    }

    if (key3) {
      value = value && value[key3];
    }

    if (key4) {

    }

    if (key5) {
      value = value && value[key5];
    }

    return value;
}

$newTime = date("Y-m-d H:i:s",strtotime("+15 minutes", strtotime($current_date)));

I have this little toy, that also deals with non generic interfaces. I'm OK with it throwing a ClassCastException if feed wrong (OK and happy)

public class TypeUtil {
    public static long castToLong(Object o) {
        Number n = (Number) o;
        return n.longValue();
    }
}

You can use the dict.fromkeys class method ...

>>> dict.fromkeys(range(5), True)
{0: True, 1: True, 2: True, 3: True, 4: True}

This is the fastest way to create a dictionary where all the keys map to the same value.

But do not use this with mutable objects:

d = dict.fromkeys(range(5), [])
# {0: [], 1: [], 2: [], 3: [], 4: []}
d[1].append(2)
# {0: [2], 1: [2], 2: [2], 3: [2], 4: [2]} !!!

If you don't actually need to initialize all the keys, a defaultdict might be useful as well:

from collections import defaultdict
d = defaultdict(True)

To answer the second part, a dict-comprehension is just what you need:

{k: k for k in range(10)}

You probably shouldn't do this but you could also create a subclass of dict which works somewhat like a defaultdict if you override __missing__:

>>> class KeyDict(dict):
...    def __missing__(self, key):
...       #self[key] = key  # Maybe add this also?
...       return key
... 
>>> d = KeyDict()
>>> d[1]
1
>>> d[2]
2
>>> d[3]
3
>>> print(d)
{}

my_list = [line.split(',') for line in open("filename.txt")]

You cannot put comments inside UWP XAML tags. Your syntax is right.

For those of you who require to redirect before fully initalizing a router using React Router or React Router Dom You can provide a redirect by simply accesing the history object and pushing a new state onto it within your constructur of app.js. Consider the following:

function getSubdomain(hostname) {
    let regexParse = new RegExp('[a-z\-0-9]{2,63}\.[a-z\.]{2,5}$');
    let urlParts = regexParse.exec(hostname);
    return hostname.replace(urlParts[0], '').slice(0, -1);
}

class App extends Component {

    constructor(props) {
        super(props);


        this.state = {
            hostState: true
        };

        if (getSubdomain(window.location.hostname).length > 0) {
            this.state.hostState = false;
            window.history.pushState('', '', './login');
        } else {
            console.log(getSubdomain(window.location.hostname));
        }

    }


    render() {

Here we want to change the output Routes dependant on a subdomain, by interacting with the history object before the component renders we can effectively redirect while still leaving our routes in tact.

window.history.pushState('', '', './login');

Per the JQuery documentation, .get() only takes the url, data (content), dataType, and success callback as its parameters. What you're really looking to do here is modify the jqXHR object before it gets sent. With .ajax(), this is done with the beforeSend() method. But since .get() is a shortcut, it doesn't allow it.

It should be relatively easy to switch your .ajax() calls to .get() calls though. After all, .get() is just a subset of .ajax(), so you can probably use all the default values for .ajax() (except, of course, for beforeSend()).

Edit:

::Looks at Jivings' answer::

Oh yeah, forgot about the cache parameter! While beforeSend() is useful for adding other headers, the built-in cache parameter is far simpler here.

You don't need to go to 64-bit to see something like this. Consider int32_t on common 32-bit platforms. It might be typedef'ed as int or as a long, but obviously only one of the two at a time. int and long are of course distinct types.

It's not hard to see that there is no workaround which makes int == int32_t == long on 32-bit systems. For the same reason, there's no way to make long == int64_t == long long on 64-bit systems.

If you could, the possible consequences would be rather painful for code that overloaded foo(int), foo(long) and foo(long long) - suddenly they'd have two definitions for the same overload?!

The correct solution is that your template code usually should not be relying on a precise type, but on the properties of that type. The whole same_type logic could still be OK for specific cases:

long foo(long x);
std::tr1::disable_if(same_type(int64_t, long), int64_t)::type foo(int64_t);

I.e., the overload foo(int64_t) is not defined when it's exactly the same as foo(long).

[edit] With C++11, we now have a standard way to write this:

long foo(long x);
std::enable_if<!std::is_same<int64_t, long>::value, int64_t>::type foo(int64_t);

[edit] Or C++20

long foo(long x);
int64_t foo(int64_t) requires (!std::is_same_v<int64_t, long>);

// Form A
public void loaddata()
{
    //do what you do in load data in order to update data in datagrid
}

then on Form B define:

// Form B
FormA obj = (FormA)Application.OpenForms["FormA"];

private void button1_Click(object sender, EventArgs e)
{
    obj.loaddata();
    datagridview1.Update();
    datagridview1.Refresh();
}

dict.items() return list of tuples, and dict.iteritems() return iterator object of tuple in dictionary as (key,value). The tuples are the same, but container is different.

dict.items() basically copies all dictionary into list. Try using following code to compare the execution times of the dict.items() and dict.iteritems(). You will see the difference.

import timeit

d = {i:i*2 for i in xrange(10000000)}  
start = timeit.default_timer() #more memory intensive
for key,value in d.items():
    tmp = key + value #do something like print
t1 = timeit.default_timer() - start

start = timeit.default_timer()
for key,value in d.iteritems(): #less memory intensive
    tmp = key + value
t2 = timeit.default_timer() - start

Output in my machine:

Time with d.items(): 9.04773592949
Time with d.iteritems(): 2.17707300186

This clearly shows that dictionary.iteritems() is much more efficient.

The only way I can think of doing this is by doing something like alert('you have a new message') when the message is received. This will flash the taskbar if the window is minimized, but it will also open a dialog box, which you may not want.

Here's a way to do it without using groups (Python 3.6 or above):

>>> re.search('2\d\d\d[01]\d[0-3]\d', 'report_20191207.xml')[0]
'20191207'

Look into the MemoryStream class.

How about the ole goto statement (i know, i know, but it works just fine here ;)

DECLARE
   v_attr char(88);
CURSOR  SELECT_USERS IS
SELECT id FROM USER_TABLE
WHERE USERTYPE = 'X';
BEGIN
    FOR user_rec IN SELECT_USERS LOOP    
        BEGIN
            SELECT attr INTO v_attr 
            FROM ATTRIBUTE_TABLE
            WHERE user_id = user_rec.id;            
         EXCEPTION
            WHEN NO_DATA_FOUND THEN
               -- user does not have attribute, continue loop to next record.
               goto end_loop;
         END;

        <<end_loop>>
        null;         
    END LOOP;
END;

Just put end_loop at very end of loop of course. The null can be substituted with a commit maybe or a counter increment maybe, up to you.

Solution

By default, Struts is using Apache “commons-io.jar” for its file upload process. To fix it, you have to include this library into your project dependency library folder.

1. Get Directly

Get “commons-io.jar” from official website – http://commons.apache.org/io/

2. Get From Maven

The prefer way is get the “commons-io.jar” from Maven repository

File : pom.xml

  <dependency>
    <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
    <version>1.4</version>
  </dependency>

STL has a max_elements function. Here is an example: http://www.cplusplus.com/reference/algorithm/max_element/

var link = $("#me").closest(":has(h3 span b)").find('h3 span b');

Example: http://jsfiddle.net/e27r8/

This uses the closest()^[docs] method to get the first ancestor that has a nested h3 span b, then does a .find().

Of course you could have multiple matches.

Otherwise, you're looking at doing a more direct traversal.

var link = $("#me").closest("h3 + div").prev().find('span b');

edit: This one works with your updated HTML.

Example: http://jsfiddle.net/e27r8/2/

EDIT: Updated to deal with updated question.

var link = $("#me").closest("h3 + *").prev().find('span b');

This makes the targeted element for .closest() generic, so that even if there is no parent, it will still work.

Example: http://jsfiddle.net/e27r8/4/

Actually, You can achieve this with current typescript:

type Grow<T, A extends Array<T>> = ((x: T, ...xs: A) => void) extends ((...a: infer X) => void) ? X : never;
type GrowToSize<T, A extends Array<T>, N extends number> = { 0: A, 1: GrowToSize<T, Grow<T, A>, N> }[A['length'] extends N ? 0 : 1];

export type FixedArray<T, N extends number> = GrowToSize<T, [], N>;

Examples:

// OK
const fixedArr3: FixedArray<string, 3> = ['a', 'b', 'c'];

// Error:
// Type '[string, string, string]' is not assignable to type '[string, string]'.
//   Types of property 'length' are incompatible.
//     Type '3' is not assignable to type '2'.ts(2322)
const fixedArr2: FixedArray<string, 2> = ['a', 'b', 'c'];

// Error:
// Property '3' is missing in type '[string, string, string]' but required in type 
// '[string, string, string, string]'.ts(2741)
const fixedArr4: FixedArray<string, 4> = ['a', 'b', 'c'];

EDIT (after a long time)

This should handle bigger sizes (as basically it grows array exponentially until we get to closest power of two):

type Shift<A extends Array<any>> = ((...args: A) => void) extends ((...args: [A[0], ...infer R]) => void) ? R : never;

type GrowExpRev<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExpRev<[...A, ...P[0]], N, P>,
  1: GrowExpRev<A, N, Shift<P>>
}[[...A, ...P[0]][N] extends undefined ? 0 : 1];

type GrowExp<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExp<[...A, ...A], N, [A, ...P]>,
  1: GrowExpRev<A, N, P>
}[[...A, ...A][N] extends undefined ? 0 : 1];

export type FixedSizeArray<T, N extends number> = N extends 0 ? [] : N extends 1 ? [T] : GrowExp<[T, T], N, [[T]]>;

mvn install is the option that is most often used.
mvn package is seldom used, only if you're debugging some issue with the maven build process.

See: http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

Note that mvn package will only create a jar file.
mvn install will do that and install the jar (and class etc.) files in the proper places if other code depends on those jars.

I usually do a mvn clean install; this deletes the target directory and recreates all jars in that location.
The clean helps with unneeded or removed stuff that can sometimes get in the way.
Rather then debug (some of the time) just start fresh all of the time.

In MacOS, I followed the below steps to make it work.

For the first time, after installation, get the username of the system.

$ cd ~
$ pwd
/Users/someuser
$ psql -d postgres -U someuser

Now that you have logged into the system, and you can create the DB.

postgres=# create database mydb;
CREATE DATABASE
postgres=# create user myuser with encrypted password 'pass123';
CREATE ROLE
postgres=# grant all privileges on database mydb to myuser;
GRANT
