A lot of these answers are super inflated and from what I can find, the answer isn't all that difficult to understand.

You can use plt.ion() if you want, but I found using plt.draw() just as effective

For my specific project I'm plotting images, but you can use plot() or scatter() or whatever instead of figimage(), it doesn't matter.

plt.figimage(image_to_show)
plt.draw()
plt.pause(0.001)

Or

fig = plt.figure()
...
fig.figimage(image_to_show)
fig.canvas.draw()
plt.pause(0.001)

If you're using an actual figure.
I used @krs013, and @Default Picture's answers to figure this out
Hopefully this saves someone from having launch every single figure on a separate thread, or from having to read these novels just to figure this out

We can have two ways of calling the functions written in pgadmin for postgre sql database.

Suppose we have defined the function as below:

CREATE OR REPLACE FUNCTION helloWorld(name text) RETURNS void AS $helloWorld$
DECLARE
BEGIN
    RAISE LOG 'Hello, %', name;
END;
$helloWorld$ LANGUAGE plpgsql;

We can call the function helloworld in one of the following way:

SELECT "helloworld"('myname');

SELECT public.helloworld('myname')

Illustrating what StaxMan has stated, this works for me

private String password;

@JsonIgnore
public String getPassword() {
    return password;
}

@JsonProperty
public void setPassword(String password) {
    this.password = password;
}

GregorianCalendar c = new GregorianCalendar();
c.setTime(yourDate);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

The key is "argument-less git-pull". When you do a git pull from a branch, without specifying a source remote or branch, git looks at the branch.<name>.merge setting to know where to pull from. git push -u sets this information for the branch you're pushing.

To see the difference, let's use a new empty branch:

$ git checkout -b test

First, we push without -u:

$ git push origin test
$ git pull
You asked me to pull without telling me which branch you
want to merge with, and 'branch.test.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
use something like the following in your configuration file:

    [branch "test"]
    remote = <nickname>
    merge = <remote-ref>

    [remote "<nickname>"]
    url = <url>
    fetch = <refspec>

See git-config(1) for details.

Now if we add -u:

$ git push -u origin test
Branch test set up to track remote branch test from origin.
Everything up-to-date
$ git pull
Already up-to-date.

Note that tracking information has been set up so that git pull works as expected without specifying the remote or branch.

Update: Bonus tips:

• As Mark mentions in a comment, in addition to git pull this setting also affects default behavior of git push. If you get in the habit of using -u to capture the remote branch you intend to track, I recommend setting your push.default config value to upstream.
• git push -u <remote> HEAD will push the current branch to a branch of the same name on <remote> (and also set up tracking so you can do git push after that).

try this angular.isUndefined(value);

https://docs.angularjs.org/api/ng/function/angular.isUndefined

The URL parameters are available in request.args, which is an ImmutableMultiDict that has a get method, with optional parameters for default value (default) and type (type) - which is a callable that converts the input value to the desired format. (See the documentation of the method for more details.)

from flask import request

@app.route('/my-route')
def my_route():
  page = request.args.get('page', default = 1, type = int)
  filter = request.args.get('filter', default = '*', type = str)

Examples with the code above:

/my-route?page=34               -> page: 34  filter: '*'
/my-route                       -> page:  1  filter: '*'
/my-route?page=10&filter=test   -> page: 10  filter: 'test'
/my-route?page=10&filter=10     -> page: 10  filter: '10'
/my-route?page=*&filter=*       -> page:  1  filter: '*'

I have the same problem. I usually resort to String#split:

"ABCDEFG".split("").each do |i|
  puts i
end

I guess you could also implement it yourself like this:

class String
  def each_char
    self.split("").each { |i| yield i }
  end
end

Edit: yet another alternative is String#each_byte, available in Ruby 1.8.6, which returns the ASCII value of each char in an ASCII string:

"ABCDEFG".each_byte do |i|
  puts i.chr # Fixnum#chr converts any number to the ASCII char it represents
end

When is a github repository not empty, like .gitignore and license

Use pull --allow-unrelated-histories and push --force-with-lease

Use commands

git init
git add .
git commit -m "initial commit"
git remote add origin https://github.com/...
git pull origin master --allow-unrelated-histories
git push --force-with-lease

Reload is easy. You should use:

location.reload(true);

And detecting back is :

window.history.pushState('', null, './');
  $(window).on('popstate', function() {
   location.reload(true);
});

<table border="1" cellspacing="0" cellpadding="0">
    <tr>
        <td>
            <table border="0">
                <tr>
                    <td>one</td>
                    <td>two</td>
                </tr>
                <tr>
                    <td>one</td>
                </tr>
            </table>
        </td>
    </tr>
</table>

It works with params if you capture an array with one element, that holds the current index.

int[] idx = { 0 };
params.forEach(e -> query.bind(idx[0]++, e));

The above code assumes, that the method forEach iterates through the elements in encounter order. The interface Iterable specifies this behaviour for all classes unless otherwise documented. Apparently it works for all implementations of Iterable from the standard library, and changing this behaviour in the future would break backward-compatibility.

If you are working with Streams instead of Collections/Iterables, you should use forEachOrdered, because forEach can be executed concurrently and the elements can occur in different order. The following code works for both sequential and parallel streams:

int[] idx = { 0 };
params.stream().forEachOrdered(e -> query.bind(idx[0]++, e));

If you want to persist data on the client machine permanently -or at least until browser cache is emptied completely, use Javascript local storage:

https://developer.mozilla.org/en-US/docs/DOM/Storage#localStorage

Do not use session storage, as it will be cleared just like a cookie with a maximum age of Zero.

I used this in my code:

<div class="sticky-top h-100">
    <nav id="sidebar" class="vh-100">
        ....

this cause your sidebar height become 100% and fixed at top.

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

I had an issue where OrderBy and ThenBy did not give me the desired result (or I just didn't know how to use them correctly).

I went with a list.Sort solution something like this.

    var data = (from o in database.Orders Where o.ClientId.Equals(clientId) select new {
    OrderId = o.id,
    OrderDate = o.orderDate,
    OrderBoolean = (SomeClass.SomeFunction(o.orderBoolean) ? 1 : 0)
    });

    data.Sort((o1, o2) => (o2.OrderBoolean.CompareTo(o1.OrderBoolean) != 0
    o2.OrderBoolean.CompareTo(o1.OrderBoolean) : o1.OrderDate.Value.CompareTo(o2.OrderDate.Value)));

I performed tests on Eclipse vs Netbeans 8.0.2, both with Java version 1.8; I used System.nanoTime() for measurements.

Eclipse:

I got the same time on both cases - around 1.564 seconds.

Netbeans:

• Using "#": 1.536 seconds
• Using "B": 44.164 seconds

So, it looks like Netbeans has bad performance on print to console.

After more research I realized that the problem is line-wrapping of the max buffer of Netbeans (it's not restricted to System.out.println command), demonstrated by this code:

for (int i = 0; i < 1000; i++) {
    long t1 = System.nanoTime();
    System.out.print("BBB......BBB"); \\<-contain 1000 "B"
    long t2 = System.nanoTime();
    System.out.println(t2-t1);
    System.out.println("");
}

The time results are less then 1 millisecond every iteration except every fifth iteration, when the time result is around 225 millisecond. Something like (in nanoseconds):

BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807
BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807
.
.
.

And so on..

Summary:

1. Eclipse works perfectly with "B"
2. Netbeans has a line-wrapping problem that can be solved (because the problem does not occur in eclipse)(without adding space after B ("B ")).

Upload the image on your server or in images hosting site where you get image link and then add the line on your website page where you get that image the line is

Judging by the documentation for date/time functions, you should be able to do something like:

Function overloading in typescript:

According to Wikipedia, (and many programming books) the definition of method/function overloading is the following:

In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations. Calls to an overloaded function will run a specific implementation of that function appropriate to the context of the call, allowing one function call to perform different tasks depending on context.

In typescript we cannot have different implementations of the same function that are called according to the number and type of arguments. This is because when TS is compiled to JS, the functions in JS have the following characteristics:

• JavaScript function definitions do not specify data types for their parameters
• JavaScript functions do not check the number of arguments when called

Therefore, in a strict sense, one could argue that TS function overloading doesn't exists. However, there are things you can do within your TS code that can perfectly mimick function overloading.

Here is an example:

function add(a: number, b: number, c: number): number;
function add(a: number, b: number): any;
function add(a: string, b: string): any;

function add(a: any, b: any, c?: any): any {
  if (c) {
    return a + c;
  }
  if (typeof a === 'string') {
    return `a is ${a}, b is ${b}`;
  } else {
    return a + b;
  }
}

The TS docs call this method overloading, and what we basically did is supplying multiple method signatures (descriptions of possible parameters and types) to the TS compiler. Now TS can figure out if we called our function correctly during compile time and give us an error if we called the function incorrectly.

If you're only interested in the output from the process, it's easiest to use subprocess' check_output function:

output = subprocess.check_output(["command", "arg1", "arg2"]);

Then output holds the program output to stdout. Check the link above for more info.

Just an observation. The input is a list of lists, but the output from the very nice solution: rotated = zip(*original[::-1]) returns a list of tuples.

This may or may not be an issue.

It is, however, easily corrected:

original = [[1, 2, 3],
            [4, 5, 6],
            [7, 8, 9]
            ]


def rotated(array_2d):
    list_of_tuples = zip(*array_2d[::-1])
    return [list(elem) for elem in list_of_tuples]
    # return map(list, list_of_tuples)

print(list(rotated(original)))

# [[7, 4, 1], [8, 5, 2], [9, 6, 3]]

The list comp or the map will both convert the interior tuples back to lists.

div1 {
    float: right;
} 
div2 {
    float: left;
}

This will work OK as long as you set clear: both for the element that separates this two column block.

I had this issue too and tried different memory expansion techniques I found on the web but had more troubles with it. I resolved to using the MySQL console source command, and of course you don't have to worry about phpMyAdmin or PHP maximum execution time and limits.

Syntax: source c:\path\to\dump_file.sql

Note: It's better to specify an absolute path to the dump file since the mysql working directory might not be known.

A more general approach:

if ( ($("body").hasClass("homepage") || $("body").hasClass("contact")) && (theLanguage == 'en-gb') )   {

       // Do something

}

You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question. The print statement is probably the most crucial piece of information. The second most crucial piece of information is the error, which you also did not include. Next time, include both of those.

print $ids should be a fairly hard statement to mess up, but it is possible. Possible reasons:

1. $ids is undefined. Gives the warning undefined value in print
2. $ids is out of scope. With use strict, gives fatal warning Global variable $ids needs explicit package name, and otherwise the undefined warning from above.
3. You forgot a semi-colon at the end of the line.
4. You tried to do print $ids $nIds, in which case perl thinks that $ids is supposed to be a filehandle, and you get an error such as print to unopened filehandle.

Explanations

1: Should not happen. It might happen if you do something like this (assuming you are not using strict):

my $var;
while (<>) {
    $Var .= $_;
}
print $var;

Gives the warning for undefined value, because $Var and $var are two different variables.

2: Might happen, if you do something like this:

if ($something) {
    my $var = "something happened!";
}
print $var;

my declares the variable inside the current block. Outside the block, it is out of scope.

3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings.

4: Also a common mistake. There are a number of ways to correctly print two variables in the same print statement:

print "$var1 $var2";  # concatenation inside a double quoted string
print $var1 . $var2;  # concatenation
print $var1, $var2;   # supplying print with a list of args

Lastly, some perl magic tips for you:

use strict;
use warnings;

# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;

# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;

my $ids  = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";

Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.

Variations:

• print "@file" is equivalent to $ids = join(' ',@file); print $ids;
• $#file will return the last index in @file. Since arrays usually start at 0, $#file + 1 is equivalent to scalar @file.

You can also do:

my $ids;
do {
    local $/;
    $ids = <$fh>;
}

By temporarily "turning off" $/, the input record separator, i.e. newline, you will make <$fh> return the entire file. What <$fh> really does is read until it finds $/, then return that string. Note that this will preserve the newlines in $ids.

Line-by-line solution:

open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
    chomp;
    $ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.

Keeping your code human readable not just machine readable. A lot of devices still can only show 80 characters at a time. Also it makes it easier for people with larger screens to multi-task by being able to set up multiple windows to be side by side.

Readability is also one of the reasons for enforced line indentation.

Most answers don't work when debugging in the following IDEs:

• PS-ISE (PowerShell ISE)
• VS Code (Visual Studio Code)

Because in those the $PSScriptRoot is empty and Resolve-Path .\ (and similars) will result in incorrect paths.

Freakydinde's answer is the only one that resolves those situations, so I up-voted that, but I don't think the Set-Location in that answer is really what is desired. So I fixed that and made the code a little clearer:

$directorypath = if ($PSScriptRoot) { $PSScriptRoot } `
    elseif ($psise) { split-path $psise.CurrentFile.FullPath } `
    elseif ($psEditor) { split-path $psEditor.GetEditorContext().CurrentFile.Path }

Don't forget to add permissions to your manifest file if you're gonna be downloading stuff from the internet!

    android:versionName="1.0">

If you are having this problem in react-native projects with one of the external library. You should remove the project and use react-native link <package-name> again. That should solve the problem.

1. Try to check it once more according to this tutorial: http://vietpad.sourceforge.net/javaonwindows.html

2. Try to reboot your system.

3. If nothing, try to run "cmd" and type there "java", does it print anything?

Tried the below program , With both the approach. 1. With clearing the arraylist obj in for loop 2. creating new New Arraylist in for loop.

List al= new ArrayList();
        for(int i=0;i<100;i++)
        {
            //List al= new ArrayList();

            for(int j=0;j<10;j++)
            {
                al.add(Integer.parseInt("" +j+i));
                //System.out.println("Obj val " +al.get(j));
            }
            //System.out.println("Hashcode : " + al.hashCode());
            al.clear();

        }

and to my surprise. the memory allocation didnt change much.

With New Arraylist approach.

Before loop total free memory: 64,909 ::

After loop total free memory: 64,775 ::

with Clear approach,

Before loop total free memory: 64,909 :: After loop total free memory: 64,765 ::

So this says there is not much difference in using arraylist.clear from memory utilization perspective.

May be this will help you.

I had a button in my layout.xml that was defined as a View as in:

final View myButton = findViewById(R.id.button1);

I was not able to change the text on it until I also defined it as a button:

final View vButton = findViewById(R.id.button1);
final Button bButton = (Button) findViewById(R.id.button1);

When I needed to change the text, I used the bButton.setText("Some Text"); and when I wanted to alter the view, I used the vButton.

Worked great!

Although above answers are correct but to make it simple for newbies, all you need to do is set margin, left and right. following code will do it provided that width is set and position is absolute:

margin: 0 auto;
left: 0;
right: 0;

Demo:

.centeredBox {_x000D_
    margin: 0 auto;_x000D_
    left: 0;_x000D_
    right: 0;_x000D_
   _x000D_
   _x000D_
   /** Position should be absolute */_x000D_
    position: absolute;_x000D_
    /** And box must have a width, any width */_x000D_
    width: 40%;_x000D_
    background: #faebd7;_x000D_
   _x000D_
   }

<div class="centeredBox">Centered Box</div>

Be careful if you are using continuous integration, you must add your libraries in the same path on your build server.

For this reason, I'd rather add jar to the local repository and, of course, do the same on the build server.

Scenario 1: Occurrence of a word in a sentence. eg: str1 = "This is an example and is easy". The occurrence of the word "is". lets str2 = "is"

string = "ABCDCDC"
substring = "CDC"

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package

import sun.misc.BASE64Encoder;

import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;

and then,

String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );

 public String getAuthantication(String username, String password) {
   String auth = new String(Base64.encode(username + ":" + password));
   return auth;
 }

Do you know sprintf? It's basically the same thing with fprintf. The first argument is the destination (the file in the case of fprintf i.e. stderr), the second argument is the format string, and the rest are the arguments as usual.

I also recommend this printf (and family) reference.

If you're using Bootstrap 4, try this:

<div class="mx-auto text-center">

=> first of all uninstall that instance from uninstall application.

=> then,clean,Rebuild,and try to deploy.

this solved my issue.hope it helps you too. Best Regards.

You can't initialize your testArray field this way, because the application resources still aren't ready.

Just change the code to:

    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Create an ArrayAdapter that will contain all list items
        ArrayAdapter<String> adapter;

        mTestArray = getResources().getStringArray(R.array.testArray);    

        /* Assign the name array to that adapter and 
        also choose a simple layout for the list items */ 
        adapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_list_item_1,
            mTestArray);

        // Assign the adapter to this ListActivity
        setListAdapter(adapter);
    }
}

Try this:

Include jQuery and use this code to get HTML of other website. Replace example.com with your website.

This method involves an external server fetching the sites HTML & sending it to you. :)

Try this and let me know if it does not work on your end:

<input type="checkbox" name='agree' ref={input => this.inputElement = input}/>
<div onClick={() => this.inputElement.click()}>Click</div>

Clicking on the div should simulate a click on the input element

If your history is sane, you can take the commits out as patch and apply them in the new repository:

cd repository
git log --pretty=email --patch-with-stat --reverse --full-index --binary -- path/to/file_or_folder > patch
cd ../another_repository
git am --committer-date-is-author-date < ../repository/patch 

Or in one line

git log --pretty=email --patch-with-stat --reverse -- path/to/file_or_folder | (cd /path/to/new_repository && git am --committer-date-is-author-date)

(Taken from Exherbo’s docs)

I had the same problem using Apache commons-fileupload. I did not find out what causes the problems especially because I have the UTF-8 encoding in the following places: 1. HTML meta tag 2. Form accept-charset attribute 3. Tomcat filter on every request that sets the "UTF-8" encoding

-> My solution was to especially convert Strings from ISO-8859-1 (or whatever is the default encoding of your platform) to UTF-8:

new String (s.getBytes ("iso-8859-1"), "UTF-8");

hope that helps

Edit: starting with Java 7 you can also use the following:

new String (s.getBytes (StandardCharsets.ISO_8859_1), StandardCharsets.UTF_8);

If you need to pair a string and an int, then how about a Map?

static Map<String, Integer> icons = new HashMap<String, Integer>();

static {
    icons.add("icon1", R.drawable.icon);
    icons.add("icon2", R.drawable.othericon);
    icons.add("someicon", R.drawable.whatever);
}

The accepted answer is fine if you can use lookarounds. However, there is also another approach to solve this problem.

If we look at the widely proposed regex for this question:

.*[^a]$

We will find that it almost works. It does not accept an empty string, which might be a little inconvinient. However, this is a minor issue when dealing with just a one character. However, if we want to exclude whole string, e.g. "abc", then:

.*[^a][^b][^c]$

won't do. It won't accept ac, for example.

There is an easy solution for this problem though. We can simply say:

.{,2}$|.*[^a][^b][^c]$

or more generalized version:

.{,n-1}$|.*[^firstchar][^secondchar]$ where n is length of the string you want forbid (for abc it's 3), and firstchar, secondchar, ... are first, second ... nth characters of your string (for abc it would be a, then b, then c).

This comes from a simple observation that a string that is shorter than the text we won't forbid can not contain this text by definition. So we can either accept anything that is shorter("ab" isn't "abc"), or anything long enough for us to accept but without the ending.

Here's an example of find that will delete all files that are not .jpg:

find . -regex '.{,3}$|.*[^.][^j][^p][^g]$' -delete

Use getChildCount() and getChildAt(int index).

Example:

LinearLayout ll = …
final int childCount = ll.getChildCount();
for (int i = 0; i < childCount; i++) {
      View v = ll.getChildAt(i);
      // Do something with v.
      // …
}

The PrimeFaces ajax events sometimes are very poorly documented, so in most cases you must go to the source code and check yourself.

p:selectOneMenu supports change event:

<p:selectOneMenu ..>
    <p:ajax event="change" update="msgtext"
        listener="#{post.subjectSelectionChanged}" />
    <!--...-->
</p:selectOneMenu>

which triggers listener with AjaxBehaviorEvent as argument in signature:

public void subjectSelectionChanged(final AjaxBehaviorEvent event)  {...}

HTTPBuilder is it. Very easy to use.

import groovyx.net.http.HTTPBuilder

def http = new HTTPBuilder('https://google.com')
def html = http.get(path : '/search', query : [q:'waffles'])

It is especially useful if you need error handling and generally more functionality than just fetching content with GET.

You could also try doing something like this:

var myArray = [{'name': 'test'}, {'name':'test2'}];
var myObject = {'name': 'test'};
myArray.splice(myArray.indexOf(myObject),1);

Trying to use underscore "once" function:

var initialize = _.once(createApplication);
initialize();
initialize();
// Application is only created once.

The answer above did not work for me (python 3.6, Anaconda, pandas 0.20.3). It worked with

conda install -c anaconda pandas 

Unfortunately I do not know how to help with Eclipse.

For IntelliJ 13, there is a checkbox in Editor's page in IDE Settings

EDIT: For IntelliJ 14, the option has been moved to Editor > General page. It's the last option in the "Other" group. (For Mac the option is under the menu "IntelliJ Idea" > "Preferences").

EDIT: For IntelliJ 16, it's the second-to-last option in Editor > General > Other.

EDIT: For IntelliJ Ultimate 2016.1, it's been moved to Editor > General > Code Completion.

EDIT: For IntelliJ Ultimate 2017.2, aka IntelliJ IDEA 2017.2.3, there are actually two options:

1. In Editor > General > Other (section) > Show quick documentation on mouse move - delay 500 ms

• Select this check box to show quick documentation for the symbol at caret. The quick documentation pop-up window appears after the specified delay.

1. In Editor > General > Code Completion (sub-item) > Autopopup documention in 1000 ms, for explicitly invoked completion

• Select this check box to have IntelliJ IDEA automatically show a pop-up window with the documentation for the class, method, or field currently highlighted in the lookup list. If this check box is not selected, use Ctrl+Q to show quick documentation for the element at caret.
• Quick documentation window will automatically pop up with the specified delay in those cases only, when code completion has been invoked explicitly. For the automatic code completion list, documentation window will only show up on pressing Ctrl+Q.

EDIT: For IntelliJ Ultimate 2020.3, the first option is now located under Editor > Code Editing > Quick Documentation > Show quick documentation on mouse move

You've got a couple of errors in there. The first is in length, and the second is in your use of unsorted (as stated by McWafflestix). You probably also want to return the list if you're going to print it:

mylist = [12, 5, 13, 8, 9, 65]

def bubble(badList):
    length = len(badList) - 2
    unsorted = True

    while unsorted:
        for element in range(0,length):
            unsorted = False

            if badList[element] > badList[element + 1]:
                hold = badList[element + 1]
                badList[element + 1] = badList[element]
                badList[element] = hold
                print badList
                unsorted = True

    return badList

print bubble(mylist)

eta: You're right, the above is buggy as hell. My bad for not testing through some more examples.

def bubble2(badList):
    swapped = True
    length = len(badList) - 2

    while swapped:
        swapped = False
        for i in range(0, length):
            if badList[i] > badList[i + 1]:

                # swap
                hold = badList[i + 1]
                badList[i + 1] = badList[i]
                badList[i] = hold

                swapped = True

    return badList

This fixed my problem.. All I needed to do was to downgrade my google-services plugin in buildscript in the build.gradle(Project) level file as follows

buildscript{
     dependencies {
        // From =>
        classpath 'com.google.gms:google-services:4.3.0'
        // To =>
        classpath 'com.google.gms:google-services:4.2.0'
        // Add dependency
        classpath 'io.fabric.tools:gradle:1.28.1'
    }
}

Use this code, Working properly

CREATE PROCEDURE [dbo].[sp_delete_item]
@ItemId int = 0
@status bit OUT

AS
Begin
 DECLARE @cnt int;
 DECLARE @status int =0;
 SET NOCOUNT OFF
 SELECT @cnt =COUNT(Id) from ItemTransaction where ItemId = @ItemId
 if(@cnt = 1)
   Begin
     return @status;
   End
 else
  Begin
   SET @status =1;
    return @status;
 End
END

Execute SP

DECLARE @statuss bit;
EXECUTE  [dbo].[sp_delete_item] 6, @statuss output;
PRINT @statuss;

You're not missing anything. RestTemplate#exchange(..) is the appropriate method to use to set request headers.

Here's an example (with POST, but just change that to GET and use the entity you want).

Here's another example.

Note that with a GET, your request entity doesn't have to contain anything (unless your API expects it, but that would go against the HTTP spec). It can be an empty String.

A much simpler solution would be to download the file using Chrome. In this manner you don't have to manually click on the save button.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        public static void Main()
        {
            Process myProcess = new Process();
            myProcess.Start("chrome.exe","http://www.com/newfile.zip");
        }
    }
}

Another method:

SELECT * 
FROM (
    SELECT * FROM table_name
    ORDER BY date ASC, time ASC 
) AS sub
GROUP BY name

GROUP BY groups on the first matching result it hits. If that first matching hit happens to be the one you want then everything should work as expected.

I prefer this method as the subquery makes logical sense rather than peppering it with other conditions.

late to the party, but if anyone comes across this, javascript has a encodeURI method

You can also do like this:

  var mocha = require('mocha')
  var describe = mocha.describe
  var it = mocha.it
  var assert = require('chai').assert

  describe('#indexOf()', function() {
    it('should return -1 when not present', function() {
      assert.equal([1,2,3].indexOf(4), -1)
    })
  })

Reference: http://mochajs.org/#require

The difference is exactly what the name implies: a group by performs a grouping operation, and an order by sorts.

If you do SELECT * FROM Customers ORDER BY Name then you get the result list sorted by the customers name.

If you do SELECT IsActive, COUNT(*) FROM Customers GROUP BY IsActive you get a count of active and inactive customers. The group by aggregated the results based on the field you specified.

I too was looking for the answer to referencing cells in a closed workbook. Here is the link to the solution (correct formula) below. I have tried it on my current project (referencing a single cell and an array of cells) and it works well with no errors. I hope it helps you.

https://www.extendoffice.com/documents/excel/4226-excel-reference-unopened-file.html

In the formula, E:\Excel file\ is the full file path of the unopened workbook, test.xlsx is the name of the workbook, Sheet2 is the sheet name which contains the cell value you need to reference from, and A:A,2,1 means the cell A2 will be referenced in the closed workbook. You can change them based on your needs.

If you want to manually select a worksheet to reference, please use this formula

=INDEX('E:\Excel file\[test.xlsx]sheetname'!A:A,2,1)

After applying this formula, you will get a Select Sheet dialog box, please select a worksheet and then click the OK button. Then the certain cell value of this worksheet will be referenced immediately.

As of php 5.4 you can use

        $dbt=debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS,2);
        $caller = isset($dbt[1]['function']) ? $dbt[1]['function'] : null;

This will not waste memory as it ignores arguments and returns only the last 2 backtrace stack entries, and will not generate notices as other answers here.

The syntax is wrong in this clause (and similar ones)

    CASE lkey WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

It's either

    CASE WHEN [condition] THEN [expression] ELSE [expression] END

or

    CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END

So in your case it would read:

    CASE WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

Check out the documentation (The CASE expression):

http://www.sqlite.org/lang_expr.html

You can use it

$params = request()->all();

without

import Illuminate\Http\Request OR

use Illuminate\Support\Facades\Request OR other.

This should be equivalent to your current code, only a lot faster:

output <- matrix(unlist(z), ncol = 10, byrow = TRUE)

JavaDoc:

The maximum queue length for incoming connection indications (a request to connect) is set to 50. If a connection indication arrives when the queue is full, the connection is refused.

You should increase "backlog" parameter of your ServerSocket, for example

int backlogSize = 50 ;
new ServerSocket(port, backlogSize);

You can use one of DatePicker library wdullaer/MaterialDateTimePicker

• First show DatePicker.

  private void showDatePicker() {
  Calendar now = Calendar.getInstance();
  DatePickerDialog dpd = DatePickerDialog.newInstance(
          HomeActivity.this,
          now.get(Calendar.YEAR),
          now.get(Calendar.MONTH),
          now.get(Calendar.DAY_OF_MONTH)
  );
  dpd.show(getFragmentManager(), "Choose Date:");
  }
  

• Then onDateSet callback store date & show TimePicker

  @Override
  public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
  Calendar cal = Calendar.getInstance();
  cal.set(year, monthOfYear, dayOfMonth);
  filter.setDate(cal.getTime());
  new Handler().postDelayed(new Runnable() {
      @Override
      public void run() {
          showTimePicker();
      }
  },500);
  }
  

• On onTimeSet callback store time

   @Override
   public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute) {
  Calendar cal = Calendar.getInstance();
  if(filter.getDate()!=null)
      cal.setTime(filter.getDate());
  cal.set(Calendar.HOUR_OF_DAY,hourOfDay);
  cal.set(Calendar.MINUTE,minute);
  }
  

Here's a numpy vectorized implementation of the Haversine Formula given by @Michael Dunn, gives a 10-50 times improvement over large vectors.

from numpy import radians, cos, sin, arcsin, sqrt

def haversine(lon1, lat1, lon2, lat2):
    """
    Calculate the great circle distance between two points 
    on the earth (specified in decimal degrees)
    """

    #Convert decimal degrees to Radians:
    lon1 = np.radians(lon1.values)
    lat1 = np.radians(lat1.values)
    lon2 = np.radians(lon2.values)
    lat2 = np.radians(lat2.values)

    #Implementing Haversine Formula: 
    dlon = np.subtract(lon2, lon1)
    dlat = np.subtract(lat2, lat1)

    a = np.add(np.power(np.sin(np.divide(dlat, 2)), 2),  
                          np.multiply(np.cos(lat1), 
                                      np.multiply(np.cos(lat2), 
                                                  np.power(np.sin(np.divide(dlon, 2)), 2))))
    c = np.multiply(2, np.arcsin(np.sqrt(a)))
    r = 6371

    return c*r

What HIVE can do which is not possible in PIG?

Partitioning can be done using HIVE but not in PIG, it is a way of bypassing the output.

What PIG can do which is not possible in HIVE?

Positional referencing - Even when you dont have field names, we can reference using the position like $0 - for first field, $1 for second and so on.

And another fundamental difference is, PIG doesn't need a schema to write the values but HIVE does need a schema.

You can connect from any external application to HIVE using JDBC and others but not with PIG.

Note: Both runs on top of HDFS (hadoop distributed file system) and the statements are converted to Map Reduce programs.

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

It's possible to decide which reactor projects to build by specifying the -pl command line argument:

$ mvn --help
[...]
 -pl,--projects <arg>                   Build specified reactor projects
                                        instead of all projects
[...]

It accepts a comma separated list of parameters in one of the following forms:

• relative path of the folder containing the POM
• [groupId]:artifactId

Thus, given the following structure:

project-root [com.mycorp:parent]
  |
  + --- server [com.mycorp:server]
  |       |
  |       + --- orm [com.mycorp.server:orm]
  |
  + --- client [com.mycorp:client]

You can specify the following command line:

mvn -pl .,server,:client,com.mycorp.server:orm clean install

to build everything. Remove elements in the list to build only the modules you please.

EDIT: as blackbuild pointed out, as of Maven 3.2.1 you have a new -el flag that excludes projects from the reactor, similarly to what -pl does:

There's yet another way to do it using Shared Connections, ie: somebody initiates the connection, using a password, and every subsequent connection will multiplex over the same channel, negating the need for re-authentication. ( And its faster too )

# ~/.ssh/config 
ControlMaster auto
ControlPath ~/.ssh/pool/%r@%h

then you just have to log in, and as long as you are logged in, the bash script will be able to open ssh connections.

You can then stop your script from working when somebody has not already opened the channel by:

ssh ... -o KbdInteractiveAuthentication=no ....

This thing can easily be done by implementing a public class that implements Comparable. This will allow you to use compareTo method which can be used with any other object to which you wish to compare.

for example you can implement it in this way:

public String compareTo(Animal oth) 
{
    return String.compare(this.population, oth.population);
}

I think this might solve your purpose.

Add the linked server first with

The following solution works for me in TensorFlow 2.3 -

def load_pb(path_to_pb):
    with tf.io.gfile.GFile(path_to_pb, 'rb') as f:
        graph_def = tf.compat.v1.GraphDef()
        graph_def.ParseFromString(f.read())
    with tf.Graph().as_default() as graph:
        tf.import_graph_def(graph_def, name='')
        return graph

tf_graph = load_pb(MODEL_FILE)
sess = tf.compat.v1.Session(graph=tf_graph)

# Show tensor names in graph
for op in tf_graph.get_operations():
    print(op.values())

where MODEL_FILE is the path to your frozen graph.

Taken from here.

Above methods didn´t work for me. This did:

  Dim arrayIsNothing As Boolean

    On Error Resume Next
    arrayIsNothing = IsNumeric(UBound(YOUR_ARRAY)) And False
    If Err.Number <> 0 Then arrayIsNothing = True
    Err.Clear
    On Error GoTo 0

    'Now you can test:
    if arrayIsNothing then ...

I had to use strcpy_s and it worked.

#include "stdafx.h"
#include<iostream>
#include<string>

using namespace std;

struct student
{
    char name[30];
    int age;
};

int main()
{

    struct student s1;
    char myname[30] = "John";
    strcpy_s (s1.name, strlen(myname) + 1 ,myname );
    s1.age = 21;

    cout << " Name: " << s1.name << " age: " << s1.age << endl;
    return 0;
}

My answer seems like less code and it works for me:

    class Nose {
      constructor() {
        this.booger = 'ready'; 
      }
      
      pick() {
        console.log('pick your nose')
      } 
    }
    
    class Ear {
      constructor() {
        this.wax = 'ready'; 
      }
      
      dig() {
        console.log('dig in your ear')
      } 
    }
    
    class Gross extends Classes([Nose,Ear]) {
      constructor() {
        super();
        this.gross = true;
      }
    }
    
    function Classes(bases) {
      class Bases {
        constructor() {
          bases.forEach(base => Object.assign(this, new base()));
        }
      }
      bases.forEach(base => {
        Object.getOwnPropertyNames(base.prototype)
        .filter(prop => prop != 'constructor')
        .forEach(prop => Bases.prototype[prop] = base.prototype[prop])
      })
      return Bases;
    }

    
    // test it
    
    var grossMan = new Gross();
    grossMan.pick(); // eww
    grossMan.dig();  // yuck!

Simply u can add this to jquery.validationEngine-en.js file

    "onlyLetterNumberSp": {
                "regex": ^[A-Za-z0-9 _]*[A-Za-z0-9][A-Za-z0-9 _]*$,
                "alertText": "* No special characters allowed"
          },

and call it in text field as

<input type="text" class="form-control validate[required,custom[onlyLetterNumberSp]]"  id="title" name="title" placeholder="Title"/>

You need to add return parameter to the command:

using (SqlConnection conn = new SqlConnection(getConnectionString()))
using (SqlCommand cmd = conn.CreateCommand())
{
    cmd.CommandText = parameterStatement.getQuery();
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.AddWithValue("SeqName", "SeqNameValue");

    var returnParameter = cmd.Parameters.Add("@ReturnVal", SqlDbType.Int);
    returnParameter.Direction = ParameterDirection.ReturnValue;

    conn.Open();
    cmd.ExecuteNonQuery();
    var result = returnParameter.Value;
}

ES6 can bind 'this'

setTimeout(() => {

 },5000);

As many people suggested, you could use std::make_pair.

But I would like to point out another method of doing the same:

revenue.push_back({"string",map[i].second});

push_back() accepts a single parameter, so you could use "{}" to achieve this!

Then simply set the android:background attribute to dotted.xml we just created. Your EditText looks like this.

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Some Text"
    android:background="@drawable/dotted" />

There's a set of useful extensions to IDLE called IDLEX that works with MacOS and Windows http://idlex.sourceforge.net/

It includes line numbering and I find it quite handy & free.

Otherwise there are a bunch of other IDEs some of which are free: https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

A simple example: We have the following array

li = [{"id":1,"name":"ronaldo"},{"id":2,"name":"messi"}]

Now, we want to find the object in the array that has id equal to 1

1. Use method next with list comprehension

next(x for x in li if x["id"] == 1 )

2. Use list comprehension and return first item

[x for x in li if x["id"] == 1 ][0]

3. Custom Function

def find(arr , id):
    for x in arr:
        if x["id"] == id:
            return x
find(li , 1)

Output all the above methods is {'id': 1, 'name': 'ronaldo'}

As long as you do not use 1.4 version, you can use explicit annotation:

example:

@Query("select count(e) from Product e where e.area.code = ?1")
long countByAreaCode(String code);

In Python 3 (I haven't tried this in Python 2), you can also simply do

with open('output.csv','w',newline='') as f:
    writer=csv.writer(f)
    writer.writerow(mystuff)
    ...

as per documentation.

More on this in the doc's footnote:

If newline='' is not specified, newlines embedded inside quoted fields will not be interpreted correctly, and on platforms that use \r\n linendings on write an extra \r will be added. It should always be safe to specify newline='', since the csv module does its own (universal) newline handling.

Instead of getting image row by row, you can put it directly to an array. For CV_8U type image, you can use byte array, for other types check here.

Mat img; // Should be CV_8U for using byte[]
int size = (int)img.total() * img.channels();
byte[] data = new byte[size];
img.get(0, 0, data); // Gets all pixels

The language standard simply doesn't allow for it. Labels can only be followed by statements, and declarations do not count as statements in C. The easiest way to get around this is by inserting an empty statement after your label, which relieves you from keeping track of the scope the way you would need to inside a block.

#include <stdio.h>
int main () 
{
    printf("Hello ");
    goto Cleanup;
Cleanup: ; //This is an empty statement.
    char *str = "World\n";
    printf("%s\n", str);
}

The Chapter object should have reference to the book it came from so I would suggest something like chapter.getBook().getTitle();

Your database table structure should have a books table and a chapters table with columns like:

books

• id
• book specific info
• etc

chapters

• id
• book_id
• chapter specific info
• etc

Then to reduce the number of queries use a join table in your search query.

I had to setup the Project SDK before selecting gradle path. Once that was set correctly, I had to choose "Use default gradle wrapper (recommended) in "Import Project from Gradle" dialog.

Still works if I remove gradle using brew:

$ brew remove gradle

run the below code in Terminal

makesure You are inside your project folder in terminal

ng g s servicename --module=app.module

Read two integers from the user. Then compute/display the remainder and quotient,

// When the larger integer is divided by the smaller integer
Console.WriteLine("Enter integer 1 please :");
double a5 = double.Parse(Console.ReadLine());
Console.WriteLine("Enter integer 2 please :");
double b5 = double.Parse(Console.ReadLine());

double div = a5 / b5;
Console.WriteLine(div);

double mod = a5 % b5;
Console.WriteLine(mod);

Console.ReadLine();

The Declarative model for Jenkins Pipelines has a restricted subset of syntax that it allows in the stage blocks - see the syntax guide for more info. You can bypass that restriction by wrapping your steps in a script { ... } block, but as a result, you'll lose validation of syntax, parameters, etc within the script block.

Your datatype is wrong, change datatype for dataType.

Check label text height and it is working on it

let labelTextSize = ((labelDescription.text)! as NSString).boundingRect(
                with: CGSize(width: labelDescription.frame.width, height: .greatestFiniteMagnitude),
                options: .usesLineFragmentOrigin,
                attributes: [.font: labelDescription.font],
                context: nil).size
            if labelTextSize.height > labelDescription.bounds.height {
                viewMoreOrLess.hide(byHeight: false)
                viewLess.hide(byHeight: false)
            }
            else {
                viewMoreOrLess.hide(byHeight: true)
                viewLess.hide(byHeight: true)

            }

If you face this issue in Linux, one of the common reasons can be that the folder "anaconda3" or "anaconda2" has root ownership. This prevents other users from writing into the folder. This can be resolved by changing the ownership of the folder from root to "USER" by running the command:

sudo chown -R $USER:$USER anaconda3

or sudo chown -R $USER:$USER <path of anaconda 3/2 folder>

Note: How to figure out whether a folder has root ownership? -- There will be a lock symbol on the top right corner of the respective folder. Or right-click on the folder->properties and you will be able to see the owner details

The -R argument lets the $USER access all the folders and files within the folder anaconda3 or anaconda2 or any respective folder. It stands for "recursive".

An easy way that generate a unique number

set @i = 0;
update vehicles set plate = CONCAT(@i:=@i+1, ROUND(RAND() * 1000)) 
order by rand();

You can use tf.convert_to_tensor():

import tensorflow as tf
import numpy as np

data = [[1,2,3],[4,5,6]]
data_np = np.asarray(data, np.float32)

data_tf = tf.convert_to_tensor(data_np, np.float32)

sess = tf.InteractiveSession()  
print(data_tf.eval())

sess.close()

Here's a link to the documentation for this method:

https://www.tensorflow.org/api_docs/python/tf/convert_to_tensor

In my case, I had a df with mixed data:

df:
                     0   1   2    ...                  242                  243                  244
0   2020-04-22T04:00:00Z   0   0  ...          3,094,409.5         13,220,425.7          5,449,201.1
1   2020-04-22T06:00:00Z   0   0  ...          3,716,941.5          8,452,012.9          6,541,599.9
....

The floats are actually objects, but I need them to be real floats.

To fix it, referencing @AMC's comment above:

def coerce_to_float(val):
    try:
       return float(val)
    except ValueError:
       return val

df = df.applymap(lambda x: coerce_to_float(x))

This isn't ideal, but I had written a lot of code and defined strings in a way similar to the method used in the question. The accepted solution required me to refactor a lot of the code so instead, I replaced every \n with "$'\n'" and this worked for me.

this work for me..

var xml  = parser.parseFromString('<?xml version="1.0" encoding="utf-8"?><root></root>', "application/xml");

Have you tried READPAST?

I've used UPDLOCK and READPAST together when treating a table like a queue.

Relying on JQuery Datepicker, but it could be done easily:

var mydate = new Date();
$.datepicker.formatDate('yy-mm-dd', mydate);

You have the alias inside of the case, it needs to be outside of the END:

Insert into TblStuff (FullName,Address,City,Zip)
Select
  Case
    When Middle is Null 
    Then Fname + LName
    Else Fname +' ' + Middle + ' '+ Lname
  End as FullName,
  Case
    When Address2 is Null Then Address1
    else Address1 +', ' + Address2 
  End as  Address,
  City as City,
  Zip as Zip
from tblImport

String[] split = data.split("\\|",-1);

This is not the actual requirement in all the time. The Drawback of above is show below:

Scenerio 1:
When all data are present:
    String data = "5|6|7||8|9|10|";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 7
    System.out.println(splt.length); //output: 8

When data is missing:

Scenerio 2: Data Missing
    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output: 8

Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.

    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output:7

What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.

Just do git checkout path/to/file-I-want-to-bring-back.txt

According to PostgreSQL documentation (4.1.2.1. String Constants):

 To include a single-quote character within a string constant, write two 
 adjacent single quotes, e.g. 'Dianne''s horse'.

See also the standard_conforming_strings parameter, which controls whether escaping with backslashes works.

You asked how to escape an Apostrophe character (') in SQL Server. All the answers above do an excellent job of explaining that.

However, depending on the situation, the Right single quotation mark character (’) might be appropriate.

(No escape characters needed)

-- Direct insert
INSERT INTO Table1 (Column1) VALUES ('John’s')

• Apostrophe (U+0027)

• Right single quotation mark (U+2019)

Man, I had the issue in one of my eclipse projects, amazingly the issue was the order of the jars in my .project file. believe it or not!

def nested1(num1): 
    print "nested1 has",num1
    def nested2(num2):
        print "nested2 has",num2,"and it can reach to",num1
        return num1+num2    #num1 referenced for reading here
    return nested2

Gives:

In [17]: my_func=nested1(8)
nested1 has 8

In [21]: my_func(5)
nested2 has 5 and it can reach to 8
Out[21]: 13

This is an example of what a closure is and how it can be used.

Andreas Grech was pretty close... it's actually this (note the reference to this instead of the item in the loop):

var $dropdown = $("#dropdown");
$.each(result, function() {
    $dropdown.append($("<option />").val(this.ImageFolderID).text(this.Name));
});

You can set the year range using this option in jQuery UI datepicker:

yearRange: "c-100:c+0", // last hundred years and current years

yearRange: "c-100:c+100", // last hundred years and future hundred years

yearRange: "c-10:c+10", // last ten years and future ten years

You might try removing the BufferedWriter and just using the FileWriter directly. On a modern system there's a good chance you're just writing to the drive's cache memory anyway.

It takes me in the range of 4-5 seconds to write 175MB (4 million strings) -- this is on a dual-core 2.4GHz Dell running Windows XP with an 80GB, 7200-RPM Hitachi disk.

Can you isolate how much of the time is record retrieval and how much is file writing?

import java.io.BufferedWriter;
import java.io.File;

Here's one way:

CString str;
str.Format("%d", 5);

In your case, try _T("%d") or L"%d" rather than "%d"

You probably do not have any de_DE locale available.

You can view a list of available locales with the locale -a command. For example, on my machine:

$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
it_CH.utf8
it_IT.utf8
POSIX

Note that if you want to set the locale to it_IT you must also specify the .utf8:

>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'it_IT')   # error!
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/locale.py", line 539, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting
>>> locale.setlocale(locale.LC_ALL, 'it_IT.utf8')
'it_IT.utf8'

To install a new locale use:

sudo apt-get install language-pack-id

where id is the language code (taken from here)

After you have installed the locale you should follow Julien Palard advice and reconfigure the locales with:

sudo dpkg-reconfigure locales

you dont have to do that in the Google chrome. Use the Internet explorer it offers the option to copy the css associated and after you copy and paste select the style and put that into another file .css to call into that html which you have created. Hope this will solve you problem than anything else:)

Try this trick .. use css shadow with (inset) option and make the deep 200px for example

Code:

box-shadow: inset 0px 0px 277px 3px #4c3f37;

.

Also for all browsers:

-moz-box-shadow: inset 0px 0px 47px 3px #4c3f37;
-webkit-box-shadow: inset 0px 0px 47px 3px #4c3f37;
box-shadow: inset 0px 0px 277px 3px #4c3f37;

and increase number to make fill your box :)

Enjoy!

Note that if you are trying to pass to a "figure level" method in seaborn (for example lmplot, catplot / factorplot, jointplot) you can and should specify this within the arguments using height and aspect.

sns.catplot(data=df, x='xvar', y='yvar', 
    hue='hue_bar', height=8.27, aspect=11.7/8.27)

See https://github.com/mwaskom/seaborn/issues/488 and Plotting with seaborn using the matplotlib object-oriented interface for more details on the fact that figure level methods do not obey axes specifications.

I had the same problem, and I was stock for many hours.

I found the solution. In my case, there was the static method defined due to that. The JVM can not create the another object of that class.

For example,

private static HttpHost proxy = new HttpHost(proxyHost, Integer.valueOf(proxyPort), "http");

A more general solution could be a extension

extension String {
    var toFloat:Float {
        return Float(self.bridgeToObjectiveC().floatValue)
    }
    var toDouble:Double {
        ....
    }
    ....
}

this for example extends the swift native String object by toFloat

You could use:

declare @foo as nvarchar(25)

select @foo = 'bar'

select @foo

I get the error in another situation, and here are the problem and the solution:

I have 2 classes derived from a same base class named LevledItem:

public partial class Team : LeveledItem
{
   //Everything is ok here!
}
public partial class Story : LeveledItem
{
   //Everything is ok here!
}

But in their DbContext, I copied some code but forget to change one of the class name:

public class MFCTeamDbContext : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //Other codes here
        modelBuilder.Entity<LeveledItem>()
            .Map<Team>(m => m.Requires("Type").HasValue(ItemType.Team));
    }

public class ProductBacklogDbContext : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //Other codes here
        modelBuilder.Entity<LeveledItem>()
            .Map<Team>(m => m.Requires("Type").HasValue(ItemType.Story));
    }

Yes, the second Map< Team> should be Map< Story>. And it cost me half a day to figure it out!

If you're working with images, you might actually prefer to not use a bias at all. In theory, that way your network will be more independent of data magnitude, as in whether the picture is dark, or bright and vivid. And the net is going to learn to do it's job through studying relativity inside your data. Lots of modern neural networks utilize this.

For other data having biases might be critical. It depends on what type of data you're dealing with. If your information is magnitude-invariant --- if inputting [1,0,0.1] should lead to the same result as if inputting [100,0,10], you might be better off without a bias.

The valueChangeListener is only necessary, if you are interested in both the old and the new value.

If you are only interested in the new value, the use of <p:ajax> or <f:ajax> is the better choice.

There are several possible reasons, why the ajax call won't work. First you should change the method signature of the handler method: drop the parameter. Then you can access your managed bean variable directly:

public void handleChange(){  
  System.out.println("here "+ getEmp().getEmployeeName());
}

At the time, the listener is called, the new value is already set. (Note that I implicitly assume that the el expression mymb.emp.employeeName is correctly backed by the corresponding getter/setter methods.)

The way I typically do it is with sprintf. So for a long you could do the following assuming that you are on a 32 bit architecture:

char buf[5] = {0}; // one extra byte for null    
sprintf(buf, "%l", var_for_long);

Um, why not just:

>>>> import os
>>>> os.path.join(dir_name, base_filename + "." + format)
'/home/me/dev/my_reports/daily_report.pdf'

:sav newfile | !rm #

Note that it does not remove the old file from the buffer list. If that's important to you, you can use the following instead:

:sav newfile | bd# | !rm #

If your content inside #childRightCol and #childRightCol are floated left or right, just add this into css:

#childRightCol:before { display: table; content: " "; }
#childRightCol:after { display: table; content: " "; clear: both; }
#childLeftCol:before { display: table; content: " "; }
#childLeftCol:after { display: table; content: " "; clear: both; }

To get the last item of a collection use LastOrDefault() and Last() extension methods

var lastItem = integerList.LastOrDefault();

OR

var lastItem = integerList.Last();

Remeber to add using System.Linq;, or this method won't be available.

I had the same problem a month ago on Windows 10. Whenever I tried to access http://localhost/ it led me to the IIS page. I tried removing the IIS feature from windows features. Once I was sure it was gone, I tried running XAMPP, but it still did not work. I did not want to mess with the configuration files. But from this, I was quite sure it had something to do with my web browser. So, deleted the cache from the web browser I was using (Google Chrome).

To do so, I went to:

Chrome > Settings > Show Advanced Settings > Privacy > Clear browsing data > Clear Cached images and files.

Its almost the same process for any web browsers. Right after that, I was able to run XAMPP without any problem!

Hope it helps!

Here you can also find more examples for values that data-toggle can have assigned. Just visit the page and then CTRL+F to search for data-toggle.

Try and retrieve the text property of the link button in the code behind:

protected void ENameLinkBtn_Click (object sender, EventArgs e)
{
   string val = ((LinkButton)sender).Text
}

Try

$ git diff --stat --color master..branchName

This will give you more info about each change, while still using the same number of lines.

You can also flip the branches to get an even clearer picture of the difference if you were to merge the other way:

$ git diff --stat --color branchName..master

I'm using such thing to clean-up the style='...' section out of tags with keeping of other attributes at the moment.

$output = preg_replace('/<([^>]+)(\sstyle=(?P<stq>["\'])(.*)\k<stq>)([^<]*)>/iUs', '<$1$5>', $input);

Or use PyInstaller as an alternative to py2exe. Here is a good starting point. PyInstaller also lets you create executables for linux and mac...

Here is how one could fairly easily use PyInstaller to solve the issue at hand:

pyinstaller oldlogs.py

From the tool's documentation:

PyInstaller analyzes myscript.py and:

• Writes myscript.spec in the same folder as the script.
• Creates a folder build in the same folder as the script if it does not exist.
• Writes some log files and working files in the build folder.
• Creates a folder dist in the same folder as the script if it does not exist.
• Writes the myscript executable folder in the dist folder.

In the dist folder you find the bundled app you distribute to your users.

Insert Into FEMALE(ID, Image)
Select '1', BulkColumn 
from Openrowset (Bulk 'D:\thepathofimage.jpg', Single_Blob) as Image

You will also need admin rights to run the query.

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

Why not:

template<typename K, typename V>
std::vector<V> MapValuesAsVector(const std::map<K, V>& map)
{
   std::vector<V> vec;
   vec.reserve(map.size());
   std::for_each(std::begin(map), std::end(map),
        [&vec] (const std::map<K, V>::value_type& entry) 
        {
            vec.push_back(entry.second);
        });
    return vec;
}

usage:

auto vec = MapValuesAsVector(anymap);

Relative paths can be best understood if you know how Java runs the program.

There is a concept of working directory when running programs in Java. Assuming you have a class, say, FileHelper that does the IO under /User/home/Desktop/projectRoot/src/topLevelPackage/.

Depending on the case where you invoke java to run the program, you will have different working directory. If you run your program from within and IDE, it will most probably be projectRoot.

• In this case $ projectRoot/src : java topLevelPackage.FileHelper it will be src.

• In this case $ projectRoot : java -cp src topLevelPackage.FileHelper it will be projectRoot.

• In this case $ /User/home/Desktop : java -cp ./projectRoot/src topLevelPackage.FileHelper it will be Desktop.

(Assuming $ is your command prompt with standard Unix-like FileSystem. Similar correspondence/parallels with Windows system)

So, your relative path root (.) resolves to your working directory. Thus to be better sure of where to write files, it's said to consider below approach.

package topLevelPackage

import java.io.File;
import java.nio.file.Path;
import java.nio.file.Paths;

public class FileHelper {

    // Not full implementation, just barebone stub for path
    public void createLocalFile() {

        // Explicitly get hold of working directory
        String workingDir = System.getProperty("user.dir");

        Path filePath = Paths.get(workingDir+File.separator+"sampleFile.txt");

        // In case we need specific path, traverse that path, rather using . or .. 
        Path pathToProjectRoot = Paths.get(System.getProperty("user.home"), "Desktop", "projectRoot");

        System.out.println(filePath);
        System.out.println(pathToProjectRoot);

    }
}

Hope this helps.

Another alternative to simulating a F5 key press would be to simply host the WebBrowser control in the Window Forms application. You use the WebBrowser.Navigate method to load your web page and then use a standard Timer and on each tick of the timer you just re-Navigate to the url which will reload the page.

I also tried to get the field1 = 'a' OR field2 = 'b'

Your code didn't work for me.

Here is my solution

$results = Mage::getModel('xyz/abc')->getCollection();
$results->addFieldToSelect('name');
$results->addFieldToSelect('keywords');
$results->addOrder('name','ASC');
$results->setPageSize(5);

$results->getSelect()->where("keywords like '%foo%' or additional_keywords  like '%bar%'");

$results->load();

echo json_encode($results->toArray());

It gives me

SELECT name, keywords FROM abc WHERE keywords like '%foo%' OR additional_keywords like '%bar%'.

It is maybe not the "magento's way" but I was stuck 5 hours on that.

Hope it will help

"When programming with C# you don’t usually need to worry about the underlying target platform. There are however a few cases when the Application and OS architecture can affect program logic, change functionality and cause unexpected exceptions."

"It is common misconception that selecting a specific target will result in the compiler generating platform specific code. This is not the case and instead it simply sets a flag in the assembly’s CLR header. This information can be easily extracted, and modified, using Microsoft’s CoreFlags tool"

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -        
RAW       0         0         0        
UDP       4         2         2        
TCP       18        16        2        
INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

Simplest answer to the question:

rand(0..n)

My understanding is that set and get are for computed properties (no backing from stored properties)

_{if you are coming from an Objective-C bare in mind that the naming conventions have changed. In Swift an iVar or instance variable is named stored property}

Example 1 (read only property) - with warning:

var test : Int {
    get {
        return test
    }
}

This will result in a warning because this results in a recursive function call (the getter calls itself).The warning in this case is "Attempting to modify 'test' within its own getter".

Example 2. Conditional read/write - with warning

var test : Int {
    get {
        return test
    }
    set (aNewValue) {
        //I've contrived some condition on which this property can be set
        //(prevents same value being set)
        if (aNewValue != test) {
            test = aNewValue
        }
    }
}

Similar problem - you cannot do this as it's recursively calling the setter. Also, note this code will not complain about no initialisers as there is no stored property to initialise.

Example 3. read/write computed property - with backing store

Here is a pattern that allows conditional setting of an actual stored property

//True model data
var _test : Int = 0

var test : Int {
    get {
        return _test
    }
    set (aNewValue) {
        //I've contrived some condition on which this property can be set
        if (aNewValue != test) {
            _test = aNewValue
        }
    }
}

Note The actual data is called _test (although it could be any data or combination of data) Note also the need to provide an initial value (alternatively you need to use an init method) because _test is actually an instance variable

Example 4. Using will and did set

//True model data
var _test : Int = 0 {

    //First this
    willSet {
        println("Old value is \(_test), new value is \(newValue)")
    }

    //value is set

    //Finaly this
    didSet {
        println("Old value is \(oldValue), new value is \(_test)")
    }
}

var test : Int {
    get {
        return _test
    }
    set (aNewValue) {
        //I've contrived some condition on which this property can be set
        if (aNewValue != test) {
            _test = aNewValue
        }
    }
}

Here we see willSet and didSet intercepting a change in an actual stored property. This is useful for sending notifications, synchronisation etc... (see example below)

Example 5. Concrete Example - ViewController Container

//Underlying instance variable (would ideally be private)
var _childVC : UIViewController? {
    willSet {
        //REMOVE OLD VC
        println("Property will set")
        if (_childVC != nil) {
            _childVC!.willMoveToParentViewController(nil)
            self.setOverrideTraitCollection(nil, forChildViewController: _childVC)
            _childVC!.view.removeFromSuperview()
            _childVC!.removeFromParentViewController()
        }
        if (newValue) {
            self.addChildViewController(newValue)
        }

    }

    //I can't see a way to 'stop' the value being set to the same controller - hence the computed property

    didSet {
        //ADD NEW VC
        println("Property did set")
        if (_childVC) {
//                var views  = NSDictionaryOfVariableBindings(self.view)    .. NOT YET SUPPORTED (NSDictionary bridging not yet available)

            //Add subviews + constraints
            _childVC!.view.setTranslatesAutoresizingMaskIntoConstraints(false)       //For now - until I add my own constraints
            self.view.addSubview(_childVC!.view)
            let views = ["view" : _childVC!.view] as NSMutableDictionary
            let layoutOpts = NSLayoutFormatOptions(0)
            let lc1 : AnyObject[] = NSLayoutConstraint.constraintsWithVisualFormat("|[view]|",  options: layoutOpts, metrics: NSDictionary(), views: views)
            let lc2 : AnyObject[] = NSLayoutConstraint.constraintsWithVisualFormat("V:|[view]|", options: layoutOpts, metrics: NSDictionary(), views: views)
            self.view.addConstraints(lc1)
            self.view.addConstraints(lc2)

            //Forward messages to child
            _childVC!.didMoveToParentViewController(self)
        }
    }
}


//Computed property - this is the property that must be used to prevent setting the same value twice
//unless there is another way of doing this?
var childVC : UIViewController? {
    get {
        return _childVC
    }
    set(suggestedVC) {
        if (suggestedVC != _childVC) {
            _childVC = suggestedVC
        }
    }
}

Note the use of BOTH computed and stored properties. I've used a computed property to prevent setting the same value twice (to avoid bad things happening!); I've used willSet and didSet to forward notifications to viewControllers (see UIViewController documentation and info on viewController containers)

I hope this helps, and please someone shout if I've made a mistake anywhere here!

No. Regular expressions in Python are handled by the re module.

article = re.sub(r'(?is)</html>.+', '</html>', article)

In general:

text_after = re.sub(regex_search_term, regex_replacement, text_before)

You find the differences explained in the detailed PHP manual on the page of require:

require is identical to include except upon failure it will also produce a fatal E_COMPILE_ERROR level error. In other words, it will halt the script whereas include only emits a warning (E_WARNING) which allows the script to continue.

See @efritz's answer for an example

A more succinct VB.Net version, if anyone is interested

Dim filePaths As Linq.IOrderedEnumerable(Of IO.FileInfo) = _
  New DirectoryInfo("c:\temp").GetFiles() _
   .OrderBy(Function(f As FileInfo) f.CreationTime)
For Each fi As IO.FileInfo In filePaths
  ' Do whatever you wish here
Next

Every class member that implements an interface exports a declaration which is semantically similar to the way VB.NET interface declarations are written, e.g.

Public Overridable Function Foo() As Integer Implements IFoo.Foo

Although the name of the class member will often match that of the interface member, and the class member will often be public, neither of those things is required. One may also declare:

Protected Overridable Function IFoo_Foo() As Integer Implements IFoo.Foo

In which case the class and its derivatives would be allowed to access a class member using the name IFoo_Foo, but the outside world would only be able to access that particular member by casting to IFoo. Such an approach is often good in cases where an interface method will have specified behavior on all implementations, but useful behavior on only some [e.g. the specified behavior for a read-only collection's IList<T>.Add method is to throw NotSupportedException]. Unfortunately, the only proper way to implement the interface in C# is:

int IFoo.Foo() { return IFoo_Foo(); }
protected virtual int IFoo_Foo() { ... real code goes here ... }

Not as nice.

The difference between starting an Activity from a Fragment and an Activity is how you get the context, because in both cases it has to be an activity.

From an activity: The context is the current activity (this)

Intent intent = new Intent(this, NewActivity.class);
startActivity(intent);

From a fragment: The context is the parent activity (getActivity()). Notice, that the fragment itself can start the activity via startActivity(), this is not necessary to be done from the activity.

Intent intent = new Intent(getActivity(), NewActivity.class);
startActivity(intent);

After looking for so many answers on StackOverflow, I haven't seen an answer to fit my needs.

That is, to make top command to keep refreshing with given keyword, and we don't have to CTRL+C / top again and again when new processes spawn.

Thus I make a new one...

Here goes the no-restart-needed version.

__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; sleep 1; done;)

Modify the __keyword and it should works. (Ubuntu 2.6.38 tested)

2.14.2015 added: The system workload part is missing with the code above. For people who cares about the "load average" part:

__keyword=name_of_process; (while :; do __arg=$(pgrep -d',' -f $__keyword); if [ -z "$__arg" ]; then top -u 65536 -n 1; else top -c -n 1 -p $__arg; fi; uptime; sleep 1; done;)

No validate will do the job.

I just cleaned up a large set of obsolete local/remote branches today.

Below is how I did it:

1. list all branch names to a text file:

git branch -a >> BranchNames.txt

2. append the branches I want to delete to command "git branch -D -r":

git branch -D -r origin/dirA/branch01 origin/dirB/branch02 origin/dirC/branch03 (... append whatever branch names)

3. execute the cmd

And this one works so much faster and reliable than "git push origin --delete".

This may not be the most smart way as listed in other answers, but this one is pretty straight forward, and easy to use.

Try following these if these might help:

Since your installation works on the terminal you installed, all the exports you did, work on the current bash and its child process. but is not spawned to new terminals.

env variables are lost if the session is closed; using .bash_profile, you can make it available in all sessions, since when a bash session starts, it 'runs' its .bashrc and .bash_profile

Now follow these steps and see if it helps:

1. type env | grep M2_HOME on the terminal that is working. This should give something like

   M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1

2. typing env | grep JAVA_HOME should give like this:

   JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home

Now you have the PATH for M2_HOME and JAVA_HOME.

If you just do ls /usr/local/apache-maven/apache-maven-3.1.1/bin, you will see mvn binary there. All you have to do now is to point to this location everytime using PATH. since bash searches in all the directory path mentioned in PATH, it will find mvn.

1. now open .bash_profile, if you dont have one just create one

   vi ~/.bash_profile

Add the following:

#set JAVA_HOME
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
export JAVA_HOME


M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1
export M2_HOME

PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
export PATH

1. save the file and type source ~/.bash_profile. This steps executes the commands in the .bash_profile file and you are good to go now.

2. open a new terminal and type mvn that should work.

it's 2021 and here's a fantastically easy plugin to upload anything:

https://pqina.nl/filepond/?ref=pqina

add your element:

<input type="file" 
class="filepond"
name="filepond" 
multiple 
data-allow-reorder="true"
data-max-file-size="3MB"
data-max-files="3">

Register any additional plugins:

  FilePond.registerPlugin(
FilePondPluginImagePreview,  
FilePondPluginImageExifOrientation,  
FilePondPluginFileValidateSize,  
FilePondPluginImageEdit);

Then wire in the element:

// Select the file input and use 
// create() to turn it into a pond
FilePond.create(
  document.querySelector('input'),

  // Use Doka.js as image editor
  imageEditEditor: Doka.create({
    utils: ['crop', 'filter', 'color']
  })
);

I use this with the additional Doka image editor to upload and transform images at https://www.yoodu.co.uk

crazy simple to setup and the guys who run it are great at support.

As you can tell I'm a fanboy.

I know question is years old, but here is a Rx implementation. It handles the length % chunkSize != 0 problem out of the box:

   public static IEnumerable<string> Chunkify(this string input, int size)
        {
            if(size < 1)
                throw new ArgumentException("size must be greater than 0");

            return input.ToCharArray()
                .ToObservable()
                .Buffer(size)            
                .Select(x => new string(x.ToArray()))
                .ToEnumerable();
        }

As an adaption of @Mike Fuchs answer, here's an even smaller solution. I'm using the Fody.AutoDependencyPropertyMarker to reduce some of the boiler plate.

The Class

public class EventCommand : TriggerAction<DependencyObject>
{
    [AutoDependencyProperty]
    public ICommand Command { get; set; }

    protected override void Invoke(object parameter)
    {
        if (Command != null)
        {
            if (Command.CanExecute(parameter))
            {
                Command.Execute(parameter);
            }
        }
    }
}

The EventArgs

public class VisibleBoundsArgs : EventArgs
{
    public Rect VisibleVounds { get; }

    public VisibleBoundsArgs(Rect visibleBounds)
    {
        VisibleVounds = visibleBounds;
    }
}

The XAML

<local:ZoomableImage>
   <i:Interaction.Triggers>
      <i:EventTrigger EventName="VisibleBoundsChanged" >
         <local:EventCommand Command="{Binding VisibleBoundsChanged}" />
      </i:EventTrigger>
   </i:Interaction.Triggers>
</local:ZoomableImage>

The ViewModel

public ICommand VisibleBoundsChanged => _visibleBoundsChanged ??
                                        (_visibleBoundsChanged = new RelayCommand(obj => SetVisibleBounds(((VisibleBoundsArgs)obj).VisibleVounds)));

I just used getLocaleString() function for my application. It should adapt the timeformat common to the locale, so no +0200 etc. Ofcourse, there will be less possibility for controlling the width of your string then.

var str = (new Date(1400167800)).toLocaleString();

boolean gps_enabled = false;
boolean network_enabled = false;

LocationManager lm = (LocationManager) mCtx
                .getSystemService(Context.LOCATION_SERVICE);

gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

Location net_loc = null, gps_loc = null, finalLoc = null;

if (gps_enabled)
    gps_loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (network_enabled)
    net_loc = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

if (gps_loc != null && net_loc != null) {

    //smaller the number more accurate result will
    if (gps_loc.getAccuracy() > net_loc.getAccuracy()) 
        finalLoc = net_loc;
    else
        finalLoc = gps_loc;

        // I used this just to get an idea (if both avail, its upto you which you want to take as I've taken location with more accuracy)

} else {

    if (gps_loc != null) {
        finalLoc = gps_loc;
    } else if (net_loc != null) {
        finalLoc = net_loc;
    }
}

It could be any one of the parameter, not just the file name or alias - for me it was the Key Password.

You can do something like this

var now = moment();
var time = now.hour() + ':' + now.minutes() + ':' + now.seconds();
time = time + ((now.hour()) >= 12 ? ' PM' : ' AM');

Prior to the introduction of git push -u, there was no git push option to obtain what you desire. You had to add new configuration statements.

If you create a new branch using:

$ git checkout -b branchB
$ git push origin branchB:branchB

You can use the git config command to avoid editing directly the .git/config file.

$ git config branch.branchB.remote origin
$ git config branch.branchB.merge refs/heads/branchB

Or you can edit manually the .git/config file to had tracking information to this branch.

[branch "branchB"]
    remote = origin
    merge = refs/heads/branchB

You can also configure your SSL in xampp/apache/conf/extra/httpd-vhost.conf like this:

<VirtualHost *:443>
    DocumentRoot C:/xampp/htdocs/yourProject
    ServerName yourProject.whatever
    SSLEngine on
    SSLCertificateFile "conf/ssl.crt/server.crt"
    SSLCertificateKeyFile "conf/ssl.key/server.key"
</VirtualHost>

I guess, it's better not change it in the httpd-ssl.conf if you have more than one project and you need SSL on more than one of them

Separate with commas:

http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505

Either way, your method signature needs to be:

@RequestMapping(value = "/GetJson", method = RequestMethod.GET) 
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
   //code to get results from db for those params.
 }

li{
    margin-left:50px;
}

or replace 50px with whatever you want.

It's pretty simple. Both will increment the value of a variable. The following two lines are equal:

x++;
++x;

The difference is if you are using the value of a variable being incremented:

x = y++;
x = ++y;

Here, both lines increment the value of y by one. However, the first one assigns the value of y before the increment to x, and the second one assigns the value of y after the increment to x.

So there's only a difference when the increment is also being used as an expression. The post-increment increments after returning the value. The pre-increment increments before.

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.

1. You can halt server, corrupt work of other people by memory consuming script without even knowing it.
2. You will not be seeing mistakes where something, let's say, infinite loop happened, and it will be harder to diagnose.
3. Such site may be easily DoSed by single user, when requesting pages with long execution time

There seems to have been an update some time in the past 3 years which changes the location of where to place themes in order to get them working.

Previosuly, themes were located in the Notepad++ installation folder. Now they are located in AppData:

C:\Users\YOUR_USER\AppData\Roaming\Notepad++\themes

My answer is an update to @Amit-IO's answer about manually copying the themes.

1. In Explorer, browse to: %AppData%\Notepad++.
2. If a folder called themes does not exist, create it.
3. Download your favourite theme from wherever (see Amit-IO's answer for a good list) and save it to %AppData%\Notepad++\themes.
4. Restart Notepad++ and then use Settings -> Style Configurator. The new theme(s) will appear in the list.

Have you tried using the dollar sign and brackets like this:

SELECT * 
FROM foo 
WHERE day >= '${CURRENT_DATE}';

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

You could try using the system stored procedure sp_help_job. This returns information on the job, its steps, schedules and servers. For example

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

SQL Books Online should contain lots of information about the records it returns.

For returning information on multiple jobs, you could try querying the following system tables which hold the various bits of information on the job

• msdb.dbo.SysJobs
• msdb.dbo.SysJobSteps
• msdb.dbo.SysJobSchedules
• msdb.dbo.SysJobServers
• msdb.dbo.SysJobHistory

Their names are fairly self-explanatory (apart from SysJobServers which hold information on when the job last run and the outcome).

Again, information on the fields can be found at MSDN. For example, check out the page for SysJobs

Adding a shell script e.g. run.sh makes it much more easier:

#!/usr/bin/env bash
export JAVA_PROGRAM_ARGS=`echo "$@"`
mvn exec:java -Dexec.mainClass="test.Main" -Dexec.args="$JAVA_PROGRAM_ARGS"

Then you are able to execute:

./run.sh arg1 arg2 arg3

For small files:

dd if=/dev/zero of=upload_test bs=file_size count=1

Where file_size is the size of your test file in bytes.

For big files:

dd if=/dev/zero of=upload_test bs=1M count=size_in_megabytes

Simply use the base transpose function t, wrapped with as.data.frame:

final_df <- as.data.frame(t(starting_df))
final_df
     A    B    C    D
a    1    2    3    4
b 0.02 0.04 0.06 0.08
c Aaaa Bbbb Cccc Dddd

Above updated. As docendo discimus pointed out, t returns a matrix. As Mark suggested wrapping it with as.data.frame gets back a data frame instead of a matrix. Thanks!

Word of caution, linux is case sensitive. That is probably why you see a "Code" and a "code" directory.

What I would do is redo the vagrant setup again and if you want to keep it simple and matching what the Homestead box has as a default make your directory in your host machine "Code" with uppercase.

You could also in the "folders" section just map to your "Code" folder in your machine, in case you decide to add more sites to your Homestead setup later. That way under /home/vagrant/Code/ you will see all your site projects and you can ass more sites pointing to their "public" directories.

function valid(id)
    {
        var textVal=document.getElementById(id).value;
        if (!textVal.match("Tryit") 
        {
            alert("Field says Tryit");
            return false;
        } 
        else 
        {
            return true;
        }
     }

Use this for expressing things

Above solution works best if multiple matching sub documents are required. $elemMatch also comes in very use if single matching sub document is required as output

db.test.find({list: {$elemMatch: {a: 1}}}, {'list.$': 1})

Result:

{
  "_id": ObjectId("..."),
  "list": [{a: 1}]
}
