its very easy. Use the bellow code, Its works for me. Here I have used fontawesome icon but you can use anything as image or any other Icon's code.

    $(document).ready(function(){
        $('.slider').slick({
            autoplay:true,
            arrows: true,
            prevArrow:"<button type='button' class='slick-prev pull-left'><i class='fa fa-angle-left' aria-hidden='true'></i></button>",
            nextArrow:"<button type='button' class='slick-next pull-right'><i class='fa fa-angle-right' aria-hidden='true'></i></button>"
        });
    });

document.write(`<td width='74'><button id='button' type='button' onclick='myfunction(\``+ name + `\`)'>click</button></td>`)

Better to use `` than "". This is a more dynamic answer.

With the xhr2 library you can globally overwrite XMLHttpRequest from your JS code. This allows you to use external libraries in node, that were intended to be run from browsers / assume they are run in a browser.

global.XMLHttpRequest = require('xhr2');

Unless I'm badly mistaken libmagic or -lmagic is not the same library as ImageMagick. You state that you want ImageMagick.

ImageMagick comes with a utility to supply all appropriate options to the compiler.

Ex:

g++ program.cpp `Magick++-config --cppflags --cxxflags --ldflags --libs` -o "prog"

Just in case you arrived here because you copied a branch name from Github, note that a remote branch is not automatically also a local branch, so a merge will not work and give the "not something we can merge" error.

In that case, you have two options:

git checkout [branchYouWantToMergeInto]
git merge origin/[branchYouWantToMerge]

or

# this creates a local branch
git checkout [branchYouWantToMerge]

git checkout [branchYouWantToMergeInto]
git merge [branchYouWantToMerge]

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

As Jeroen says there are scoping issues: if you set 'count' outside the loop, you can't modify it inside the loop.

You can defeat this behavior by using an object rather than a scalar for 'count':

{% set count = [1] %}

You can now manipulate count inside a forloop or even an %include%. Here's how I increment count (yes, it's kludgy but oh well):

{% if count.append(count.pop() + 1) %}{% endif %} {# increment count by 1 #}

SELECT from_unixtime( UNIX_TIMESTAMP(fild_with_timestamp) ) from "your_table"
This work for me

this is possible with jQuery $.ajax() method

$.ajax(serverUrl, {
   type: OutageViewModel.Id() == 0 ? "POST" : "PUT",
   data: dataToSave,
   statusCode: {
      200: function (response) {
         alert('1');
         AfterSavedAll();
      },
      201: function (response) {
         alert('1');
         AfterSavedAll();
      },
      400: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      },
      404: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      }
   }, success: function () {
      alert('1');
   },
});

Using a context manager as Paul Price sugggested

import numpy as np


class fullprint:
    'context manager for printing full numpy arrays'

    def __init__(self, **kwargs):
        kwargs.setdefault('threshold', np.inf)
        self.opt = kwargs

    def __enter__(self):
        self._opt = np.get_printoptions()
        np.set_printoptions(**self.opt)

    def __exit__(self, type, value, traceback):
        np.set_printoptions(**self._opt)


if __name__ == '__main__': 
    a = np.arange(1001)

    with fullprint():
        print(a)

    print(a)

    with fullprint(threshold=None, edgeitems=10):
        print(a)

We wrote a library which includes 3 ways to select an option:

selectOption(option: ElementFinder |Locator | string, timeout?: number): Promise<void>

selectOptionByIndex(select: ElementFinder | Locator | string, index: number, timeout?: number): Promise<void>

selectOptionByText(select: ElementFinder | Locator | string, text: string, timeout?: number): Promise<void>

Additional feature of this functions is that they wait for the element to be displayed before any action on the select is performed.

You can find it on npm @hetznercloud/protractor-test-helper. Typings for TypeScript are provided as well.

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

Try this:

.divider {_x000D_
 width:500px;_x000D_
 text-align:center;_x000D_
}_x000D_
_x000D_
.divider hr {_x000D_
 margin-left:auto;_x000D_
 margin-right:auto;_x000D_
 width:40%;_x000D_
_x000D_
}_x000D_
_x000D_
.left {_x000D_
 float:left;_x000D_
}_x000D_
_x000D_
.right {_x000D_
 float:right;_x000D_
}

<div class="divider">_x000D_
    <hr class="left"/>TEXT<hr class="right" />_x000D_
</div>

I think may be more automatic, grunt task usemin take care to do all this jobs for you, only need some configuration:

https://stackoverflow.com/a/33481683/1897196

I think this should be what you want:

System.Reflection.Assembly.GetEntryAssembly().Location

This returns the assembly that was first loaded when the process started up, which would seem to be what you want.

GetCallingAssembly won't necessarily return the assembly you want in the general case, since it returns the assembly containing the method immediately higher in the call stack (i.e. it could be in the same DLL).

xargs will do what you want:

git ls-files | xargs cat | wc -l

But with more information and probably better, you can do:

git ls-files | xargs wc -l

PowerShell is a good choice ;) It is very easy to enumerate files in given directory, read them and process.

The script could look like this:

Get-ChildItem C:\Projects *.config -recurse |
    Foreach-Object {
        $c = ($_ | Get-Content) 
        $c = $c -replace '<add key="Environment" value="Dev"/>','<add key="Environment" value="Demo"/>'
        [IO.File]::WriteAllText($_.FullName, ($c -join "`r`n"))
    }

I split the code to more lines to be readable for you. Note that you could use Set-Content instead of [IO.File]::WriteAllText, but it adds new line at the end. With WriteAllText you can avoid it.

Otherwise the code could look like this: $c | Set-Content $_.FullName.

Nothing above worked for me. Everything was correct.

Close the Visual Studio and reopen again. This fixed the issue in my case.

The problem could have been caused by different versions of visual studio. I have Visual studio 2017 and 2019. I had opened the project on both the versions simultaneously. This might have created different set of vs files.

Close any instance of the Visual Studio and open again.

Actually, it is

private const int TheAnswer = 42;

At least if you look at the .NET library, which IMO is the best way to decide naming conventions - so your code doesn't look out of place.

You will need to convert your response to json before you can access response.body

From the docs

fetch(url)
  .then(response => response.json())
  .then(json => {
    console.log('parsed json', json) // access json.body here
  })

Another way (for 2000 / 2005/2012/2014):

IF ((SELECT OBJECTPROPERTY( OBJECT_ID(N'table_name_here'), 'TableHasIdentity')) = 1)
    PRINT 'Yes'
ELSE
    PRINT 'No'

NOTE: table_name_here should be schema.table, unless the schema is dbo.

If you use Java and spring MVC you just need to add the following annotation to your method returning your page :

@CrossOrigin(origins = "*")

"*" is to allow your page to be accessible from anywhere. See https://developer.mozilla.org/fr/docs/Web/HTTP/Headers/Access-Control-Allow-Origin for more details about that.

   PropertyConfigurator.configure("log4j.xml");
   Logger logger = LoggerFactory.getLogger(MyClass.class);
   logger.error(message);

I faced similar problem on windows server 2012 STD 64 bit , my problem is resolved after updating windows with all available windows updates.

MaxLength is now supported as of .NET 4.7.2, so as long as you upgrade your project to .NET 4.7.2 or above, it will work automatically.

You can see this in the release notes here - specifically:

Enable ASP.NET developers to specify MaxLength attribute for Multiline asp:TextBox. [449020, System.Web.dll, Bug]

Simplified version of the above: (from here: https://stackoverflow.com/a/32800728/47226)

function isNullOrWhitespace( input ) {
  return !input || !input.trim();
}

I think there is no out-of-the-box support for that in VS Code.

You can install a plugin to give you similar functionality. Eg.:

https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints

Or the more famous:

https://marketplace.visualstudio.com/items?itemName=xyz.local-history

Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore file also solves this problem).

I have made a script in ASP code to detect browser, browser version, OS and OS version. The reason for me to do this in ASP was because i want to store the data in a log-database. So I had to detect the browser serverside.

Here is the code:

D:project/contactlist npm install then D:project/contactlist ng new client

D:project/contactlist/client ng serve

this worked for me for some reason i had to delete the client folder and start npm install from the contactlist folder. i tried every thing even clearing the cache and finally this worked.

No, the underscore is the only continuation character. Personally I prefer the occasional use of a continuation character to being forced to use it always as in C#, but apart from the comments issue (which I'd agree is sometimes annoying), getting things to line up is not an issue.

With VS2008 at any rate, just select the second and following lines, hit the tab key several times, and it moves the whole lot across.

If it goes a tiny bit too far, you can delete the excess space a character at a time. It's a little fiddly, but it stays put once it's saved.

On the rare cases where this isn't good enough, I sometimes use the following technique to get it all to line up:

dim results as String = ""
results += "from a in articles "
results += "where a.articleID = 4 " 'and now you can add comments
results += "select a.articleName"

It's not perfect, and I know those that prefer C# will be tut-tutting, but there it is. It's a style choice, but I still prefer it to endless semi-colons.

Now I'm just waiting for someone to tell me I should have used a StringBuilder ;-)

Yes, you can use it. Here is how:

1. Your Project -> right click -> Import -> File System -> yourjar.jar
2. Your Project -> right click -> Properties -> Java Build Path -> Libraries -> Add Jar -> yourjar.jar

This video might be useful in case you are having some issues.

A common trick is to check like this:

trim(TextBox1.Value & vbnullstring) = vbnullstring

this will work for spaces, empty strings, and genuine null values

You need to use a long literal:

obj.function(600851475143l);  // note the "l" at the end

But I would expect that function to run out of memory (or time) ...

If you can't use bat files to set up your environment, then your only likely option is to set up a system wide environment variable. You can find these by doing

1. Right click "My Computer"
2. Select properties
3. Select the "advanced" tab
4. Click the "environment variables" button
5. In the "System variables" section, add the new environment variable that you desire
6. "Ok" all the way out to accept your changes

I don't know if you'd have to restart visual studio, but seems unlikely. HTH

Try prepending the doublequote with a backslash in your expresssion:

sed 's/\"//g' [file name]

Note: I have verified this in the latest version of IE, and other browsers like Mozilla and Chrome and this works for me. Hope it works for others as well.

if (data == "" || data == undefined) {
    alert("Falied to open PDF.");
} else { //For IE using atob convert base64 encoded data to byte array
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        var byteCharacters = atob(data);
        var byteNumbers = new Array(byteCharacters.length);
        for (var i = 0; i < byteCharacters.length; i++) {
            byteNumbers[i] = byteCharacters.charCodeAt(i);
        }
        var byteArray = new Uint8Array(byteNumbers);
        var blob = new Blob([byteArray], {
            type: 'application/pdf'
        });
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    } else { // Directly use base 64 encoded data for rest browsers (not IE)
        var base64EncodedPDF = data;
        var dataURI = "data:application/pdf;base64," + base64EncodedPDF;
        window.open(dataURI, '_blank');
    }

}

You don't need the assignment operator. append returns None.

Opening a file creates it and (unless append ('a') is set) overwrites it with emptyness, such as this:

open(filename, 'w').close()

It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1 is null or ConfigurationManager.AppSettings.Get("Url") is returning null.

Yes it is:

a = numpy.array([1,2,3])

This question is asking 2 very different things:

1. What is the easiest way to compare strings in Python, ignoring case?
2. I guess I'm looking for an equivalent to C's stricmp().

Since #1 has been answered very well already (ie: str1.lower() < str2.lower()) I will answer #2.

def strincmp(str1, str2, numchars=None):
    result = 0
    len1 = len(str1)
    len2 = len(str2)
    if numchars is not None:
        minlen = min(len1,len2,numchars)
    else:
        minlen = min(len1,len2)
    #end if
    orda = ord('a')
    ordz = ord('z')

    i = 0
    while i < minlen and 0 == result:
        ord1 = ord(str1[i])
        ord2 = ord(str2[i])
        if ord1 >= orda and ord1 <= ordz:
            ord1 = ord1-32
        #end if
        if ord2 >= orda and ord2 <= ordz:
            ord2 = ord2-32
        #end if
        result = cmp(ord1, ord2)
        i += 1
    #end while

    if 0 == result and minlen != numchars:
        if len1 < len2:
            result = -1
        elif len2 < len1:
            result = 1
        #end if
    #end if

    return result
#end def

Only use this function when it makes sense to as in many instances the lowercase technique will be superior.

I only work with ascii strings, I'm not sure how this will behave with unicode.

    public static List<string> SplitByMaxLength(this string str)
    {
        List<string> splitString = new List<string>();

        for (int index = 0; index < str.Length; index += MaxLength)
        {
            splitString.Add(str.Substring(index, Math.Min(MaxLength, str.Length - index)));
        }

        return splitString;
    }

Ok. Everyone has given answers with tricks but i think the right way to achieve this is by

Connecting the following action to the "Did End On Exit" event in Interface Builder. (right-click the TextField and cntrl-drag from 'Did end on exit' to the following method.

-(IBAction)hideTheKeyboard:(id)sender
{

The idea of why scroll view is not scrolling because you set the content size for scrolling less than the size of the scroll view, which is wrong. You should set the content size bigger than the size of your scroll view to navigate through it while scrolling.

The same idea with zooming, you set the min and max value for zooming which will applied through zooming action.

welcome :)

If you want for some reason to convert your file to base-64 string. Like if you want to pass it via internet, etc... you can do this

Byte[] bytes = File.ReadAllBytes("path");
String file = Convert.ToBase64String(bytes);

And correspondingly, read back to file:

Byte[] bytes = Convert.FromBase64String(b64Str);
File.WriteAllBytes(path, bytes);

This is now possible with C# 7.0's pattern matching. For example:

var myString = "abcDEF";

switch(myString)
{
    case string x when x.StartsWith("abc"):
        //Do something here
        break;
}

If you're using PHP and none of the above worked (as it was my case), you need to set the locale with utf-8 encoding.

Like this

setlocale(LC_ALL, 'fr_CA.utf-8');

SELECT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%wild%';

What I do in these cases is:

• In the server, move the cursor back to the last known good commit:

  git push -f origin <last_known_good_commit>:<branch_name>
  

• Locally, do the same:

  git reset --hard <last_known_good_commit>
  #         ^^^^^^
  #         optional
  

See a full example on a branch my_new_branch that I created for this purpose:

$ git branch
my_new_branch

This is the recent history after adding some stuff to myfile.py:

$ git log
commit 80143bcaaca77963a47c211a9cbe664d5448d546

    Adding new stuff in myfile.py

commit b4zad078237fa48746a4feb6517fa409f6bf238e
Author: me
Date:   Tue Mar 18 12:46:59 2016 +0100

    Initial commit

I want to get rid of the last commit, which was already pushed, so I run:

$ git push -f origin b4zad078237fa48746a4feb6517fa409f6bf238e:my_new_branch
Total 0 (delta 0), reused 0 (delta 0)
To [email protected]:me/myrepo.git
 + 80143bc...b4zad07 b4zad078237fa48746a4feb6517fa409f6bf238e -> my_new_branch (forced update)

Nice! Now I see the file that was changed on that commit (myfile.py) shows in "not staged for commit":

$ git status
On branch my_new_branch
Your branch is up-to-date with 'origin/my_new_branch'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   myfile.py

no changes added to commit (use "git add" and/or "git commit -a")

Since I don't want these changes, I just move the cursor back locally as well:

$ git reset --hard b4zad078237fa48746a4feb6517fa409f6bf238e
HEAD is now at b4zad07 Initial commit

So now HEAD is in the previous commit, both in local and remote:

$ git log
commit b4zad078237fa48746a4feb6517fa409f6bf238e

    Initial commit

Use a literal control and write your html like this:

literal1.text = "<h2><p>Notify:</p> alert</h2>";

With CSS3 flexbox. Simple.

ul {
  display: flex;
  justify-content: center;
}

ul li {
  padding: 0 8px;
}

You can use usort, like this:

usort($array,function($first,$second){
    return strcmp($first->name, $second->name);
});

I think refilling the same adapter with different data would be more or most better technique. Put this method in your Adapter class with right argument (the data list you want to display as names in my case) Call this where u update the data of list with updated list (names in my case)

public void refill(ArrayList<BeanDatabase> names) {
    list.clear();
    list.addAll(names);
    list.notifyDataSetChanged();
}

If you change the adapter or set the adapter again and again on when the list updates, then force close error would surely cause problems at some point. (Error:List data been updated but adapter doesn't notify the List View)

This answer similar to others, but using preferred stringr::str_detect and dplyr rownames_to_column.

library(tidyverse)

mtcars %>% 
  rownames_to_column("type") %>% 
  filter(stringr::str_detect(type, 'Toyota|Mazda') )

to_timestamp()

You need to use to_timestamp() to convert your string to a proper timestamp value:

to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

to_date()

If your column is of type DATE (which also supports seconds), you need to use to_date()

to_date('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

Example

To get this into a where condition use the following:

select * 
from TableA 
where startdate >= to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
  and startdate <= to_timestamp('12-01-2012 21:25:33', 'dd-mm-yyyy hh24:mi:ss')

Note

You never need to use to_timestamp() on a column that is of type timestamp.

If you want to have bare run command in gdb to execute your program with redirections and arguments, you can use set args:

% gdb ./a.out
(gdb) set args arg1 arg2 <file
(gdb) run

I was unable to achieve the same behaviour with --args parameter, gdb fiercely escapes the redirections, i.e.

% gdb --args echo 1 2 "<file"
(gdb) show args
Argument list to give program being debugged when it is started is "1 2 \<file".
(gdb) run
...
1 2 <file
...

This one actually redirects the input of gdb itself, not what we really want here

% gdb --args echo 1 2 <file
zsh: no such file or directory: file

I know this thread is slightly older, but here's what worked for me when I got this error earlier, knowing I was nowhere near memory limit- both answers were found above.

Hopefully this could help someone in the future if they need it.

1. Checked CHMOD on dir folder... found somehow the symbolic notation was different. CHMOD dir folder to 755
2. dbfilename permissions were good, no changes needed
3. Restarted redis-server
4. (Should've done this first, but ah well) Referenced the redis-server.log and found that the error was the result of access being denied.

Again- unsure how the permissions on the DIR folder got changed, but I'm assuming CHMOD back to 755 and restarting redis-server took care of it as I was able to ping redis server afterwards.

Also- to note, redis did have ownership of the dbfilename and DIR folder.

The key is to select the target of your emulator to, for example: Google APIs (ver 18). If you select, for example, just Jellybean 18 (without API) you will not be able to test apps that require Google services such as map. Keep in mind that you must first download the Google API of your favorite version with the Android SDK Manager.

This is a good practice and it is far better than juggling with most workarounds.

Extract jar file for ex. with winrar and use CAVAJ:

Cavaj Java Decompiler is a graphical freeware utility that reconstructs Java source code from CLASS files.

You are trying to set int value to TextView so you are getting this issue. To solve this try below one option

option 1:

tv.setText(no+"");

Option2:

tv.setText(String.valueOf(no));

It is as simple as

hash.values
#=> [["a", "b", "c"], ["b", "c"]]

this will return a new array populated with the values from hash

if you want to store that new array do

array_of_values = hash.values
#=> [["a", "b", "c"], ["b", "c"]]

array_of_values
 #=> [["a", "b", "c"], ["b", "c"]]

One millionaire has N cars. You want to get all (4) wheels.

One (1) query loads all the cars, but for each (N) car a separate query is submitted for loading wheels.

Costs:

Assume indexes fit into ram.

1 + N query parsing and planing + index searching AND 1 + N + (N * 4) plate access for loading payload.

Assume indexes don't fit into ram.

Additional costs in worst case 1 + N plate accesses for loading index.

Summary

Bottle neck is plate access (ca. 70 times per second random access on hdd) An eager join select would also access the plate 1 + N + (N * 4) times for payload. So if the indexes fit into ram - no problem, its fast enough because only ram operations involved.

it's probably better to override the backbutton so you can handle the event before the view is popped for things such as user confirmation.

in viewDidLoad create a UIBarButtonItem and set self.navigationItem.leftBarButtonItem to it passing in a sel

- (void) viewDidLoad
{
// change the back button to cancel and add an event handler
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@”back”
style:UIBarButtonItemStyleBordered
target:self
action:@selector(handleBack:)];

self.navigationItem.leftBarButtonItem = backButton;
[backButton release];

}
- (void) handleBack:(id)sender
{
// pop to root view controller
[self.navigationController popToRootViewControllerAnimated:YES];

}

Then you can do things like raise an UIAlertView to confirm the action, then pop the view controller, etc.

Or instead of creating a new backbutton, you can conform to the UINavigationController delegate methods to do actions when the back button is pressed.

If you have successfully installed Apache web server and Perl please follow the following steps to run cgi script using perl on ubuntu systems.

Before starting with CGI scripting it is necessary to configure apache server in such a way that it recognizes the CGI directory (where the cgi programs are saved) and allow for the execution of programs within that directory.

1. In Ubuntu cgi-bin directory usually resides in path /usr/lib , if not present create the cgi-bin directory using the following command.cgi-bin should be in this path itself.

    mkdir /usr/lib/cgi-bin
   

2. Issue the following command to check the permission status of the directory.

    ls -l /usr/lib | less
   

Check whether the permission looks as “drwxr-xr-x 2 root root 4096 2011-11-23 09:08 cgi- bin” if yes go to step 3.

If not issue the following command to ensure the appropriate permission for our cgi-bin directory.

     sudo chmod 755 /usr/lib/cgi-bin
     sudo chmod root.root /usr/lib/cgi-bin

3. Give execution permission to cgi-bin directory

    sudo chmod 755 /usr/lib/cgi-bin
   

Thus your cgi-bin directory is ready to go. This is where you put all your cgi scripts for execution. Our next step is configure apache to recognize cgi-bin directory and allow execution of all programs in it as cgi scripts.

Configuring Apache to run CGI script using perl

1. A directive need to be added in the configuration file of apache server so it knows the presence of CGI and the location of its directories. Initially go to location of configuration file of apache and open it with your favorite text editor

   cd /etc/apache2/sites-available/ 
   sudo gedit 000-default.conf
   

2. Copy the below content to the file 000-default.conf between the line of codes “DocumentRoot /var/www/html/” and “ErrorLog $ {APACHE_LOG_DIR}/error.log”

   ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
   <Directory "/usr/lib/cgi-bin">
   AllowOverride None
   Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
   Require all granted
   

3. Restart apache server with the following code

   sudo service apache2 restart
   

4. Now we need to enable cgi module which is present in newer versions of ubuntu by default

   sudo a2enmod cgi.load
   sudo a2enmod cgid.load
   

5. At this point we can reload the apache webserver so that it reads the configuration files again.

   sudo service apache2 reload
   

The configuration part of apache is over now let us check it with a sample cgi perl program.

Testing it out

1. Go to the cgi-bin directory and create a cgi file with extension .pl

   cd /usr/lib/cgi-bin/
   sudo gedit test.pl
   

2. Copy the following code on test.pl and save it.

   #!/usr/bin/perl -w
   print “Content-type: text/html\r\n\r\n”;
   print “CGI working perfectly!! \n”;
   

3. Now give the test.pl execution permission.

   sudo chmod 755 test.pl
   

4. Now open that file in your web browser http://Localhost/cgi-bin/test.pl

5. If you see the output “CGI working perfectly” you are ready to go.Now dump all your programs into the cgi-bin directory and start using them.

NB: Don't forget to give your new programs in cgi-bin, chmod 755 permissions so as to run it successfully without any internal server errors.

First run:

find . -type f -name "*.py[c|o]" -exec rm -f {} +

Then add:

export PYTHONDONTWRITEBYTECODE=1

To ~/.profile

In my Python 2.7 interpreter, the same whos command that exists in MATLAB exists in Python. It shows the same details as the MATLAB analog (variable name, type, and value/data).

Note that in the Python interpreter, whos lists all variables in the "interactive namespace".

Just had to write a "live" example at work :)

This one supports multiple values for UserId on the same date.

Columns: UserId, Value, Date

SELECT
   DISTINCT UserId,
   MAX(Date) OVER (PARTITION BY UserId ORDER BY Date DESC),
   MAX(Values) OVER (PARTITION BY UserId ORDER BY Date DESC)
FROM
(
   SELECT UserId, Date, SUM(Value) As Values
   FROM <<table_name>>
   GROUP BY UserId, Date
)

You can use FIRST_VALUE instead of MAX and look it up in the explain plan. I didn't have the time to play with it.

Of course, if searching through huge tables, it's probably better if you use FULL hints in your query.

Well, unless you really need to squeeze the performance out of your function, just go with what is easiest to maintain and understand. A regular expression would look like this:

For additional performance, you can either pre-compile it or just tell it to compile on first call (subsequent calls will be faster.)

public static string RemoveSpecialCharacters(string str)
{
    return Regex.Replace(str, "[^a-zA-Z0-9_.]+", "", RegexOptions.Compiled);
}

Assume you make the access_token last very long, and don't have refresh_token, so in one day, hacker get this access_token and he can access all protected resources!

But if you have refresh_token, the access_token's live time is short, so the hacker is hard to hack your access_token because it will be invalid after short period of time. Access_token can only be retrieved back by using not only refresh_token but also by client_id and client_secret, which hacker doesn't have.

Use the Insert method:

ti.Insert(0, initialItem);

You would probably would have to set the child div to have position: absolute.

Update your child style to

#parentDiv .childDiv
{
  height:100px;
  width:30px;
  background-color:#999;
  position:absolute;
  top:207px;
}

For scala

import org.apache.spark.sql.functions.regexp_replace
import org.apache.spark.sql.functions.col
data.withColumn("addr_new", regexp_replace(col("addr_line"), "\\*", ""))

According to @Enno Gröper 's post, I've tried the SSLContext constructor and it works well on my machine. code as below:

import ssl
ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
urllib2.urlopen("https://your-test-server.local", context=ctx)

if you need opener, just added this context like:

opener = urllib2.build_opener(urllib2.HTTPSHandler(context=ctx))

NOTE: all above test environment is python 2.7.12. I use PROTOCOL_SSLv23 here since the doc says so, other protocol might also works but depends on your machine and remote server, please check the doc for detail.

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`
  

This works very well for me. Go to the android-support-v7-appcompat project and open the file "project.properties" and insert this lines if missing:

target=android-25_x000D_
compile=android-21

You can make use of the first-child selector

<div class="sidebar">
    <div class="box">
        <p> 
            Text is here
         </p>
     </div>
    <div class="box">
        <p> 
            Text is here
         </p>
     </div>
</div>

and in CSS

.box {
    padding: 10px;
    text-align: justify;
    margin-top: 20px;
}
.box:first-child {
    margin-top: none;
}

Example: http://jsbin.com/ozarot/edit#javascript,html,live

Using the {# #} notation, like so:

{# Everything you see here is a comment. It won't show up in the HTML output. #}

You may find this query useful:

SELECT * 
FROM sys.dm_exec_requests
WHERE DB_NAME(database_id) = 'YourDBName' 
AND blocking_session_id <> 0

Another way, inspired from previous posts to make an extension.

We can put the image on the right or on the left

extension UITextField {

enum Direction {
    case Left
    case Right
}

// add image to textfield
func withImage(direction: Direction, image: UIImage, colorSeparator: UIColor, colorBorder: UIColor){
    let mainView = UIView(frame: CGRect(x: 0, y: 0, width: 50, height: 45))
    mainView.layer.cornerRadius = 5

    let view = UIView(frame: CGRect(x: 0, y: 0, width: 50, height: 45))
    view.backgroundColor = .white
    view.clipsToBounds = true
    view.layer.cornerRadius = 5
    view.layer.borderWidth = CGFloat(0.5)
    view.layer.borderColor = colorBorder.cgColor
    mainView.addSubview(view)

    let imageView = UIImageView(image: image)
    imageView.contentMode = .scaleAspectFit
    imageView.frame = CGRect(x: 12.0, y: 10.0, width: 24.0, height: 24.0)
    view.addSubview(imageView)

    let seperatorView = UIView()
    seperatorView.backgroundColor = colorSeparator
    mainView.addSubview(seperatorView)

    if(Direction.Left == direction){ // image left
        seperatorView.frame = CGRect(x: 45, y: 0, width: 5, height: 45)
        self.leftViewMode = .always
        self.leftView = mainView
    } else { // image right
        seperatorView.frame = CGRect(x: 0, y: 0, width: 5, height: 45)
        self.rightViewMode = .always
        self.rightView = mainView
    }

    self.layer.borderColor = colorBorder.cgColor
    self.layer.borderWidth = CGFloat(0.5)
    self.layer.cornerRadius = 5
}

}

Use :

if let myImage = UIImage(named: "my_image"){
    textfield.withImage(direction: .Left, image: myImage, colorSeparator: UIColor.orange, colorBorder: UIColor.black)
}

Enjoy :)

From my understanding, the currently accepted answer only changes the order of the factor levels, not the actual labels (i.e., how the levels of the factor are called). To illustrate the difference between levels and labels, consider the following example:

Turn cyl into factor (specifying levels would not be necessary as they are coded in alphanumeric order):

    mtcars2 <- mtcars %>% mutate(cyl = factor(cyl, levels = c(4, 6, 8))) 
    mtcars2$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 4 6 8

Change the order of levels (but not the labels itself: cyl is still the same column)

    mtcars3 <- mtcars2 %>% mutate(cyl = factor(cyl, levels = c(8, 6, 4))) 
    mtcars3$cyl[1:5]
    #[1] 6 6 4 6 8
    #Levels: 8 6 4
    all(mtcars3$cyl==mtcars2$cyl)
    #[1] TRUE

Assign new labels to cyl The order of the labels was: c(8, 6, 4), hence we specify new labels as follows:

    mtcars4 <- mtcars3 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_8", 
                                                               "new_value_for_6", 
                                                               "new_value_for_4" )))
    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

Note how this column differs from our first columns:

    all(as.character(mtcars4$cyl)!=mtcars3$cyl) 
    #[1] TRUE 
    #Note: TRUE here indicates that all values are unequal because I used != instead of ==
    #as.character() was required as the levels were numeric and thus not comparable to a character vector

More details:

If we were to change the levels of cyl using mtcars2 instead of mtcars3, we would need to specify the labels differently to get the same result. The order of labels for mtcars2 was: c(4, 6, 8), hence we specify new labels as follows

    #change labels of mtcars2 (order used to be: c(4, 6, 8)
    mtcars5 <- mtcars2 %>% mutate(cyl = factor(cyl, labels = c("new_value_for_4", 
                                                               "new_value_for_6", 
                                                               "new_value_for_8" )))

Unlike mtcars3$cyl and mtcars4$cyl, the labels of mtcars4$cyl and mtcars5$cyl are thus identical, even though their levels have a different order.

    mtcars4$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_8 new_value_for_6 new_value_for_4

    mtcars5$cyl[1:5]
    #[1] new_value_for_6 new_value_for_6 new_value_for_4 new_value_for_6 new_value_for_8
    #Levels: new_value_for_4 new_value_for_6 new_value_for_8

    all(mtcars4$cyl==mtcars5$cyl)
    #[1] TRUE

    levels(mtcars4$cyl) == levels(mtcars5$cyl)
    #1] FALSE  TRUE FALSE

Use this script: https://github.com/ricardobranco777/docker-volumes.sh

This does preserve data in volumes.

Example usage:

# Stop the container   
docker stop $CONTAINER

# Create a new image   
docker commit $CONTAINER $CONTAINER

# Save image
docker save -o $CONTAINER.tar $CONTAINER

# Save the volumes (use ".tar.gz" if you want compression)
docker-volumes.sh $CONTAINER save $CONTAINER-volumes.tar

# Copy image and volumes to another host
scp $CONTAINER.tar $CONTAINER-volumes.tar $USER@$HOST:

# On the other host:
docker load -i $CONTAINER.tar
docker create --name $CONTAINER [<PREVIOUS CONTAINER OPTIONS>] $CONTAINER

# Load the volumes
docker-volumes.sh $CONTAINER load $CONTAINER-volumes.tar

# Start container
docker start $CONTAINER

Composition means creating an object to a class which has relation with that particular class. Suppose Student has relation with Accounts;

An Inheritance is, this is the previous class with the extended feature. That means this new class is the Old class with some extended feature. Suppose Student is Student but All Students are Human. So there is a relationship with student and human. This is Inheritance.

use

SELECT DISTINCT Date FROM buy ORDER BY Date

so MySQL removes duplicates

BTW: using explicit column names in SELECT uses less resources in PHP when you're getting a large result from MySQL

You can make an empty commit with git commit --allow-empty, but that will not allow you to commit an empty folder structure as git does not know or care about folders as objects themselves -- just the files they contain.

First, in bash "[" is just a command, which expects string "]" as a last argument, so the whitespace before the closing bracket (as well as between "!" and "-d" which need to be two separate arguments too) is important:

if [ ! -d /home/mlzboy/b2c2/shared/db ]; then
  mkdir -p /home/mlzboy/b2c2/shared/db;
fi

Second, since you are using -p switch to mkdir, this check is useless, because this is what does in the first place. Just write:

mkdir -p /home/mlzboy/b2c2/shared/db;

and thats it.

I don't have enough reputation to comment on answers, but I just wanted to note that downloading the JSR-311 api by itself will not work. You need to download the reference implementation (jersey).

Only downloading the api from the JSR page will give you a ClassNotFoundException when the api tries to look for an implementation at runtime.

This is code I used in Windows. It works.

    name,value = item.split('=', 1)

The "bind" operation is basically saying, "use this local UDP port for sending and receiving data. In other words, it allocates that UDP port for exclusive use for your application. (Same holds true for TCP sockets).

When you bind to "0.0.0.0" (INADDR_ANY), you are basically telling the TCP/IP layer to use all available adapters for listening and to choose the best adapter for sending. This is standard practice for most socket code. The only time you wouldn't specify 0 for the IP address is when you want to send/receive on a specific network adapter.

Similarly if you specify a port value of 0 during bind, the OS will assign a randomly available port number for that socket. So I would expect for UDP multicast, you bind to INADDR_ANY on a specific port number where multicast traffic is expected to be sent to.

The "join multicast group" operation (IP_ADD_MEMBERSHIP) is needed because it basically tells your network adapter to listen not only for ethernet frames where the destination MAC address is your own, it also tells the ethernet adapter (NIC) to listen for IP multicast traffic as well for the corresponding multicast ethernet address. Each multicast IP maps to a multicast ethernet address. When you use a socket to send to a specific multicast IP, the destination MAC address on the ethernet frame is set to the corresponding multicast MAC address for the multicast IP. When you join a multicast group, you are configuring the NIC to listen for traffic sent to that same MAC address (in addition to its own).

Without the hardware support, multicast wouldn't be any more efficient than plain broadcast IP messages. The join operation also tells your router/gateway to forward multicast traffic from other networks. (Anyone remember MBONE?)

If you join a multicast group, all the multicast traffic for all ports on that IP address will be received by the NIC. Only the traffic destined for your binded listening port will get passed up the TCP/IP stack to your app. In regards to why ports are specified during a multicast subscription - it's because multicast IP is just that - IP only. "ports" are a property of the upper protocols (UDP and TCP).

You can read more about how multicast IP addresses map to multicast ethernet addresses at various sites. The Wikipedia article is about as good as it gets:

The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered by using the Ethernet MAC address range 01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff. This is 23 bits of available address space. The first octet (01) includes the broadcast/multicast bit. The lower 23 bits of the 28-bit multicast IP address are mapped into the 23 bits of available Ethernet address space.

JSON.parse() takes a JSON string and transforms it into a JavaScript object.

JSON.stringify() takes a JavaScript object and transforms it into a JSON string.

const myObj = {
      name: 'bipon',
      age: 25,
      favoriteFood: 'fish curry'
};

 const myObjStr = JSON.stringify(myObj);

console.log(myObjStr);
// "{"name":"bipon","age":26,"favoriteFood":"fish curry"}"

console.log(JSON.parse(myObjStr));
 // Object {name:"bipon",age:26,favoriteFood:"fish curry"}

const myArr = ['simon', 'gomez', 'john'];

const myArrStr = JSON.stringify(myArr);

console.log(myArrStr);
// "["simon","gomez","john"]"

console.log(JSON.parse(myArrStr));
// ["simon","gomez","john"]

select right(rtrim('94342KMR'),3)

This will fetch the last 3 right string.

select substring(rtrim('94342KMR'),1,len('94342KMR')-3)

This will fetch the remaining Characters.

int counter = 0;

for(int i = 1; ; i++) {
    if(isPrime(i)
        counter++;

    if(counter == userInput) {
        print(i);
        break;
    }
}

Edit: Your prime function could use a bit of work. Here's one that I have written:

private static boolean isPrime(long n) {
    if(n < 2)
        return false;

    for (long i = 2; i * i <= n; i++) {
        if (n % i == 0)
            return false;
    }
    return true;
}

Note - you only need to go up to sqrt(n) when looking at factors, hence the i * i <= n

I Found an easy way to do this,I've tested it,it works Properly. First I created a Windows Project,on the form I Inserted a TextBox and I named it textBox1 then I inserted a button named button1,then add a class named class1. in the class1 I created a TextBox:

class class1
    {
     public static TextBox txt1=new TextBox();  //a global textbox to interfece with      form1
    public static void Hello()
      {
       txt1.Text="Hello";
      }
    }

Now in your Form Do this:

public partial class Form1 : Form
    {
     public Form1()
     {
      InitializeComponent();  
     }
     private void button1_Click(object sender, EventArgs e)
      {
       class1.txt1=textBox1;
       class1.Hello();
       }
    }

in the button1_Click I coppied the object textBox1 into txt1,so now txt1 has the properties of textBox1 and u can change textBox1 text in another form or class.

UseMethod("t") is telling you that t() is a (S3) generic function that has methods for different object classes.

The S3 method dispatch system

For S3 classes, you can use the methods function to list the methods for a particular generic function or class.

> methods(t)
[1] t.data.frame t.default    t.ts*       

   Non-visible functions are asterisked
> methods(class="ts")
 [1] aggregate.ts     as.data.frame.ts cbind.ts*        cycle.ts*       
 [5] diffinv.ts*      diff.ts          kernapply.ts*    lines.ts        
 [9] monthplot.ts*    na.omit.ts*      Ops.ts*          plot.ts         
[13] print.ts         time.ts*         [<-.ts*          [.ts*           
[17] t.ts*            window<-.ts*     window.ts*      

   Non-visible functions are asterisked

"Non-visible functions are asterisked" means the function is not exported from its package's namespace. You can still view its source code via the ::: function (i.e. stats:::t.ts), or by using getAnywhere(). getAnywhere() is useful because you don't have to know which package the function came from.

> getAnywhere(t.ts)
A single object matching ‘t.ts’ was found
It was found in the following places
  registered S3 method for t from namespace stats
  namespace:stats
with value

function (x) 
{
    cl <- oldClass(x)
    other <- !(cl %in% c("ts", "mts"))
    class(x) <- if (any(other)) 
        cl[other]
    attr(x, "tsp") <- NULL
    t(x)
}
<bytecode: 0x294e410>
<environment: namespace:stats>

The S4 method dispatch system

The S4 system is a newer method dispatch system and is an alternative to the S3 system. Here is an example of an S4 function:

> library(Matrix)
Loading required package: lattice
> chol2inv
standardGeneric for "chol2inv" defined from package "base"

function (x, ...) 
standardGeneric("chol2inv")
<bytecode: 0x000000000eafd790>
<environment: 0x000000000eb06f10>
Methods may be defined for arguments: x
Use  showMethods("chol2inv")  for currently available ones.

The output already offers a lot of information. standardGeneric is an indicator of an S4 function. The method to see defined S4 methods is offered helpfully:

> showMethods(chol2inv)
Function: chol2inv (package base)
x="ANY"
x="CHMfactor"
x="denseMatrix"
x="diagonalMatrix"
x="dtrMatrix"
x="sparseMatrix"

getMethod can be used to see the source code of one of the methods:

> getMethod("chol2inv", "diagonalMatrix")
Method Definition:

function (x, ...) 
{
    chk.s(...)
    tcrossprod(solve(x))
}
<bytecode: 0x000000000ea2cc70>
<environment: namespace:Matrix>

Signatures:
        x               
target  "diagonalMatrix"
defined "diagonalMatrix"

There are also methods with more complex signatures for each method, for example

require(raster)
showMethods(extract)
Function: extract (package raster)
x="Raster", y="data.frame"
x="Raster", y="Extent"
x="Raster", y="matrix"
x="Raster", y="SpatialLines"
x="Raster", y="SpatialPoints"
x="Raster", y="SpatialPolygons"
x="Raster", y="vector"

To see the source code for one of these methods the entire signature must be supplied, e.g.

getMethod("extract" , signature = c( x = "Raster" , y = "SpatialPolygons") )

It will not suffice to supply the partial signature

getMethod("extract",signature="SpatialPolygons")
#Error in getMethod("extract", signature = "SpatialPolygons") : 
#  No method found for function "extract" and signature SpatialPolygons

Functions that call unexported functions

In the case of ts.union, .cbindts and .makeNamesTs are unexported functions from the stats namespace. You can view the source code of unexported functions by using the ::: operator or getAnywhere.

> stats:::.makeNamesTs
function (...) 
{
    l <- as.list(substitute(list(...)))[-1L]
    nm <- names(l)
    fixup <- if (is.null(nm)) 
        seq_along(l)
    else nm == ""
    dep <- sapply(l[fixup], function(x) deparse(x)[1L])
    if (is.null(nm)) 
        return(dep)
    if (any(fixup)) 
        nm[fixup] <- dep
    nm
}
<bytecode: 0x38140d0>
<environment: namespace:stats>

Functions that call compiled code

Note that "compiled" does not refer to byte-compiled R code as created by the compiler package. The <bytecode: 0x294e410> line in the above output indicates that the function is byte-compiled, and you can still view the source from the R command line.

Functions that call .C, .Call, .Fortran, .External, .Internal, or .Primitive are calling entry points in compiled code, so you will have to look at sources of the compiled code if you want to fully understand the function. This GitHub mirror of the R source code is a decent place to start. The function pryr::show_c_source can be a useful tool as it will take you directly to a GitHub page for .Internal and .Primitive calls. Packages may use .C, .Call, .Fortran, and .External; but not .Internal or .Primitive, because these are used to call functions built into the R interpreter.

Calls to some of the above functions may use an object instead of a character string to reference the compiled function. In those cases, the object is of class "NativeSymbolInfo", "RegisteredNativeSymbol", or "NativeSymbol"; and printing the object yields useful information. For example, optim calls .External2(C_optimhess, res$par, fn1, gr1, con) (note that's C_optimhess, not "C_optimhess"). optim is in the stats package, so you can type stats:::C_optimhess to see information about the compiled function being called.

Compiled code in a package

If you want to view compiled code in a package, you will need to download/unpack the package source. The installed binaries are not sufficient. A package's source code is available from the same CRAN (or CRAN compatible) repository that the package was originally installed from. The download.packages() function can get the package source for you.

download.packages(pkgs = "Matrix", 
                  destdir = ".",
                  type = "source")

This will download the source version of the Matrix package and save the corresponding .tar.gz file in the current directory. Source code for compiled functions can be found in the src directory of the uncompressed and untared file. The uncompressing and untaring step can be done outside of R, or from within R using the untar() function. It is possible to combine the download and expansion step into a single call (note that only one package at a time can be downloaded and unpacked in this way):

untar(download.packages(pkgs = "Matrix",
                        destdir = ".",
                        type = "source")[,2])

Alternatively, if the package development is hosted publicly (e.g. via GitHub, R-Forge, or RForge.net), you can probably browse the source code online.

Compiled code in a base package

Certain packages are considered "base" packages. These packages ship with R and their version is locked to the version of R. Examples include base, compiler, stats, and utils. As such, they are not available as separate downloadable packages on CRAN as described above. Rather, they are part of the R source tree in individual package directories under /src/library/. How to access the R source is described in the next section.

Compiled code built into the R interpreter

If you want to view the code built-in to the R interpreter, you will need to download/unpack the R sources; or you can view the sources online via the R Subversion repository or Winston Chang's github mirror.

Uwe Ligges's R news article (PDF) (p. 43) is a good general reference of how to view the source code for .Internal and .Primitive functions. The basic steps are to first look for the function name in src/main/names.c and then search for the "C-entry" name in the files in src/main/*.

You can encapsulate any widget in your code with a new widget called (Visibility), this is from the yellow lamp at the very left side of the widget that you want it to be in-visible

example: say you want to make a row invisible:

1. Click in the lamp and choose (Wrap with widget)
2. Rename the widget to Visibility
3. Add the visible property and set it to false

4. The Child of the newly created widget (Visibility Widget) is the Widget that you want it to be invisible

             Visibility(
                 visible: false,
                 child: Row(
                   crossAxisAlignment: CrossAxisAlignment.start,
                   children: <Widget>[
                     SizedBox(
                       width: 10,
                     ),
                     Text("Search",
                       style: TextStyle(fontSize: 20
                       ),),
                   ],
                 ),
               ),
   

I hope it will help someone in the future

Instead use Width and Height in user controls, use MinHeight and MinWidth. Then you can configure the UC well, and will be able to stretch inside other window.

Well, as Im seeing in WPF Microsoft made a re-thinking about windows properties and behaviors, but so far, I didn't miss anything from olds windows forms, in WPF the controls are there, but in a new point of view.

If they're contiguous, you can just do

x[2:6] = []

If you want to remove noncontiguous indexes, it's a little trickier.

x = [v for i,v in enumerate(x) if i not in frozenset((2,3,4,5))] 

BOUML is free, can reverse-engineer Java and C++

The chart seem to be async so you will probably need to provide a callback when the animation has finished or else the canvas will be empty.

var options = {
    bezierCurve : false,
    onAnimationComplete: done  /// calls function done() {} at end
};

try this

public boolean isPrebuiltTestButtonVisible() {
    try {

        if (preBuiltTestButton.isEnabled()) {

            return true;

        } else {

            return false;
        }

    } catch (Exception e) {

        e.printStackTrace();
        return false;
    }
}

git ls-files --deleted -z | xargs -0 git rm --cached

This will remove all deleted files that were previous tracked by git, as well as handle the case where your filenames have spaces in them.

Depending on your POSIX variant, you may need to use xargs -0 -r: this will cause xargs to gracefully exit when piped null content.

EDIT: --cached and --deleted flags are used in tandem to safeguard against accidentally deleting files that have not already been deleted.

With the inspiration of @Joel Ostblom

For those who already have a workable dictionary for merely aggregation, you can use/modify the following code for the newer version aggregation, separating aggregation and renaming part. Please be aware of the nested dictionary if there are more than 1 item.

def agg_translate_agg_rename(input_agg_dict):
    agg_dict = {}
    rename_dict = {}
    for k, v in input_agg_dict.items():
        if len(v) == 1:
            agg_dict[k] = list(v.values())[0]
            rename_dict[k] = list(v.keys())[0]
        else:
            updated_index = 1
            for nested_dict_k, nested_dict_v in v.items():
                modified_key = k + "_" + str(updated_index)
                agg_dict[modified_key] = nested_dict_v
                rename_dict[modified_key] = nested_dict_k
                updated_index += 1
    return agg_dict, rename_dict

one_dict = {"column1": {"foo": 'sum'}, "column2": {"mean": 'mean', "std": 'std'}}
agg, rename = agg_translator_aa(one_dict)

We get

agg = {'column1': 'sum', 'column2_1': 'mean', 'column2_2': 'std'}
rename = {'column1': 'foo', 'column2_1': 'mean', 'column2_2': 'std'}

Please let me know if there is a smarter way to do it. Thanks.

First, don't declare variables using var, but

public $my_value;

Then you can access it using

$this->my_value;

and not

$this->$my_value;

Try this:

List<string> names = new List<string>("Tom,Scott,Bob".Split(','));
names.Reverse();

it's easy

every folder of those you downloaded has a different kind of roboto font, means they are different fonts

example: "roboto_regular_macroman"

to use any of them:

1- extract the folder of the font you want to use

2- upload it near the css file

3- now include it in the css file

example for including the font which called "roboto_regular_macroman":

@font-face {
font-family: 'Roboto';
src: url('roboto_regular_macroman/Roboto-Regular-webfont.eot');
src: url('roboto_regular_macroman/Roboto-Regular-webfont.eot?#iefix') format('embedded-opentype'),
     url('roboto_regular_macroman/Roboto-Regular-webfont.woff') format('woff'),
     url('roboto_regular_macroman/Roboto-Regular-webfont.ttf') format('truetype'),
     url('roboto_regular_macroman/Roboto-Regular-webfont.svg#RobotoRegular') format('svg');
font-weight: normal;
font-style: normal;
}

watch for the path of the files, here i uploaded the folder called "roboto_regular_macroman" in the same folder where the css is

then you can now simply use the font by typing font-family: 'Roboto';

Ted Hopp is correct, from the API Documentation :

public void copyPixelsToBuffer (Buffer dst)

"... After this method returns, the current position of the buffer is updated: the position is incremented by the number of elements written in the buffer. "

and

public ByteBuffer get (byte[] dst, int dstOffset, int byteCount)

"Reads bytes from the current position into the specified byte array, starting at the specified offset, and increases the position by the number of bytes read."

You have to setup a SSH private key, you can review this page, how to do the setup on Mac, if you are on linux the guide should be almost the same, on Windows you would need tool like MSYS.

Don't nest <form> tags, that will not work. Just use Bootstrap classes.

Bootstrap 3

<form class="form-horizontal" role="form">
    <div class="form-group">

      <div class="col-md-3">
          <input type="text" class="form-control" id="inputType" placeholder="Type">
      </div>
    </div>
    <div class="form-group">
        <span class="col-md-2 control-label">Metadata</span>
        <div class="col-md-6">
            <div class="form-group row">
                <label for="inputKey" class="col-md-1 control-label">Key</label>

Updated Answer:

It's been commented multiple times that this is not the correct answer to this question, and I agree. Back when this answer was written, IE 9 was still new (about 8 months old) and many developers including myself needed a solution for <= IE 9. IE 9 is when IE started supporting background-origin. However, it's been over six and a half years, so here's the updated solution which I highly recommend over using an actual border. In case < IE 9 support is needed. My original answer can be found below the demo snippet. It uses an opaque border to simulate padding for background images.

#hello {
  padding-right: 10px;
  background-color:green;
  background: url("https://placehold.it/15/5C5/FFF") no-repeat scroll right center #e8e8e8;
  background-origin: content-box;
}

<p id="hello">I want the background icon to have padding to it too!I want the background icon twant the background icon to have padding to it too!I want the background icon to have padding to it too!I want the background icon to have padding to it too!</p>

Original Answer:

you can fake it with a 10px border of the same color as the background:

http://jsbin.com/eparad/edit#javascript,html,live

#hello {
   border: 10px solid #e8e8e8;
   background-color: green;
   background: url("http://www.costascuisine.com/images/buttons/collapseIcon.gif")
               no-repeat scroll right center #e8e8e8;
}

When I had this issue with tf.train.string_input_producer() and tf.train.batch() initializing the local variables before I started the Coordinator solved the problem. I had been getting the error when I initialized the local variables after starting the Coordinator.

If you don't want the image to affect the layout at all (and float on top of other content) you can apply the following CSS to the image:

position:absolute;
right:0;
top:0;

If you want it to float at the right of a particular parent section, you can add position: relative to that section.

It means assign the key to $user and the variable to $pass

When you assign an array, you do it like this

$array = array("key" => "value");

It uses the same symbol for processing arrays in foreach statements. The '=>' links the key and the value.

According to the PHP Manual, the '=>' created key/value pairs.

Also, Equal or Greater than is the opposite way: '>='. In PHP the greater or less than sign always goes first: '>=', '<='.

And just as a side note, excluding the second value does not work like you think it would. Instead of only giving you the key, It actually only gives you a value:

$array = array("test" => "foo");

foreach($array as $key => $value)
{
    echo $key . " : " . $value; // Echoes "test : foo"
}

foreach($array as $value)
{
    echo $value; // Echoes "foo"
}

Old question but i feel i should add the following, even more because .net 4.0 had already launched at the time the question was written.

Starting with .net 4.0 there is the namespace System.Collections.Concurrent which includes collections that are thread-safe.

The collection System.Collections.Concurrent.ConcurrentDictionary<> does exactly what you want. It has the AddOrUpdate() method with the added advantage of being thread-safe.

If you're in a high-performance scenario and not handling multiple threads the already given answers of map[key] = value are faster.

In most scenarios this performance benefit is insignificant. If so i'd advise to use the ConcurrentDictionary because:

1. It is in the framework - It is more tested and you are not the one who has to maintain the code
2. It is scalable: if you switch to multithreading your code is already prepared for it

The alternative way to check if an array is empty could be:

count($array)>0

It works for me without that error

I had a similar problem - maybe my solution will help. I just installed MSSQL EX 2012 (default install) and tried to connect with VS2012 EX. No joy. I then looked at the services, confirmed that SQL Server (SQLEXPRESS) was, indeed running.

However, I saw another interesting service called SQL Server Browser that was disabled. I enabled it, fired it and was then able to retrieve the server name in a new connection in VS2012 EX and connect.

Odd that they would disable a service required for VS to connect.

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

&something gives you the address of the std::vector object, not the address of the data it holds. &something.begin() gives you the address of the iterator returned by begin() (as the compiler warns, this is not technically allowed because something.begin() is an rvalue expression, so its address cannot be taken).

Assuming the container has at least one element in it, you need to get the address of the initial element of the container, which you can get via

• &something[0] or &something.front() (the address of the element at index 0), or

• &*something.begin() (the address of the element pointed to by the iterator returned by begin()).

In C++11, a new member function was added to std::vector: data(). This member function returns the address of the initial element in the container, just like &something.front(). The advantage of this member function is that it is okay to call it even if the container is empty.

We monitor this from the application code, just to include the time required to establish/close the connection and transmit data across the network. It's pretty straight-forward...

Dim Duration as TimeSpan
Dim StartTime as DateTime = DateTime.Now

'Call the database here and execute your SQL statement

Duration = DateTime.Now.Subtract(StartTime)
Console.WriteLine(String.Format("Query took {0} seconds", Duration.TotalSeconds.ToString()))
Console.ReadLine()

\n dosen't work. Use html tags

document.write("<br>");
document.write("?");

I found this problem continued even when setting the BODY MARGIN to zero.

However it turns out there is an easy fix. All you need to do is give your HEADER tag a 1px border, aswell as setting the BODY MARGIN to zero, as shown below.

body { margin:0px; }

header { border:1px black solid; }

You may also need to change the MARGIN to zero for any H1, H2, etc. elements you have within your HEADER div. This will get rid of any extra space which may show around the text.

Not sure why this works, but I use Chrome browser. Obviously you can also change the colour of the border to match your header colour.

For me, when typing the url, a user accidentally used a / instead of a ? to start the query parameters

e.g.:

url.com/endpoint/parameter=SomeValue&otherparameter=Another+value

which should have been:

url.com/endpoint?parameter=SomeValue&otherparameter=Another+value

RoboSpice Vs. Volley

From https://groups.google.com/forum/#!topic/robospice/QwVCfY_glOQ

• RoboSpice(RS) is service based and more respectful of Android philosophy than Volley. Volley is thread based and this is not the way background processing should take place on Android. Ultimately, you can dig down both libs and find that they are quite similar, but our way to do background processing is more Android oriented, it allow us, for instance, to tell users that RS is actually doing something in background, which would be hard for volley (actually it doesn't at all).
• RoboSpice and volley both offer nice features like prioritization, retry policies, request cancellation. But RS offers more : a more advanced caching and that's a big one, with cache management, request aggregation, more features like repluging to a pending request, dealing with cache expiry without relying on server headers, etc.
• RoboSpice does more outside of UI Thread : volley will deserialize your POJOs on the main thread, which is horrible to my mind. With RS your app will be more responsive.
• In terms of speed, we definitely need metrics. RS has gotten super fast now, but still we don't have figure to put here. Volley should theoretically be a bit faster, but RS is now massively parallel... who knows ?
• RoboSpice offers a large compatibility range with extensions. You can use it with okhttp, retrofit, ormlite (beta), jackson, jackson2, gson, xml serializer, google http client, spring android... Quite a lot. Volley can be used with ok http and uses gson. that's it.
• Volley offers more UI sugar that RS. Volley provides NetworkImageView, RS does provide a spicelist adapter. In terms of feature it's not so far, but I believe Volley is more advanced on this topic.
• More than 200 bugs have been solved in RoboSpice since its initial release. It's pretty robust and used heavily in production. Volley is less mature but its user base should be growing fast (Google effect).
• RoboSpice is available on maven central. Volley is hard to find ;)

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

MYSQL 8.0:

Search my.ini in disk, we will find this folder:

C:\ProgramData\MySQL\MySQL Server 8.0
It's ProgramData, not Program file

Data is in sub-folder: \Data.

Each database owns a folder, each table is file, each index is 1+ files.

Here is a sample database sakila:

callback from adapter to activity can be done using registering listener in form of interface: Make an interface:

      public MyInterface{
         public void  yourmethod(//incase needs parameters );
         }

In Adapter Let's Say MyAdapter:

    public MyAdapter extends BaseAdapter{
       private MyInterface listener;

    MyAdapter(Context context){
        try {
            this. listener = (( MyInterface ) context);
              } catch (ClassCastException e) {
               throw new ClassCastException("Activity must implement MyInterface");
          }

//do this where u need to fire listener l

          try {
                listener . yourmethod ();
            } catch (ClassCastException exception) {
               // do something
            }

      In Activity Implement your method:


         MyActivity extends AppCompatActivity implements MyInterface{

                yourmethod(){
                //do whatever you want
                     }
                     }

You can use, contentEquals() function. It may help you..

The old way:

xcopy [source] [destination] /E

xcopy is deprecated. Robocopy replaces Xcopy. It comes with Windows 8, 8.1 and 10.

robocopy [source] [destination] /E

robocopy has several advantages:

• copy paths exceeding 259 characters
• multithreaded copying

More details here.

Try array_merge.

$array1 = array('Item 1');

$array2 = array('Item 2');

$array3 = array_merge($array1, $array2);

I think its because you are not assigning a key to either, so they both have key of 0, and the + does not re-index, so its trying to over write it.

You can also define a scale transformation, with CSS like so:

.larger-icon {
 transform:scale(2);
}

I had the same error, even after re-running aws configure, and inputting a new AWS_ACESS_KEY_ID and AWS_SECRET_ACCESS_KEY.

What fixed it for me was to delete my ~/.aws/credentials file and re-run aws configure.

It seems that my ~/.aws/credentials file had an additional value: aws_session_token which was causing the error. After deleting and re-creating the ~/.aws/configure using the command aws configure, there is now only values for aws_access_key_id and aws_secret_access_key.

Use urllib.request.urlopen():

import urllib.request
with urllib.request.urlopen('http://www.example.com/') as f:
    html = f.read().decode('utf-8')

This is the most basic way to use the library, minus any error handling. You can also do more complex stuff such as changing headers.

On Python 2, the method is in urllib2:

import urllib2
response = urllib2.urlopen('http://www.example.com/')
html = response.read()

HTML

<div class="preload">
<img src="http://i.imgur.com/KUJoe.gif">
</div>

<div class="content">
I would like to display a loading bar before the entire page is loaded. 
</div>

JAVASCRIPT

$(function() {
    $(".preload").fadeOut(2000, function() {
        $(".content").fadeIn(1000);        
    });
});?

CSS

.content {display:none;}
.preload { 
    width:100px;
    height: 100px;
    position: fixed;
    top: 50%;
    left: 50%;
}

I'm not sure that there is any option for simply printing the full effective search path.

But: the search path consists of directories specified by -L options on the command line, followed by directories added to the search path by SEARCH_DIR("...") directives in the linker script(s). So you can work it out if you can see both of those, which you can do as follows:

If you're invoking ld directly:

• The -L options are whatever you've said they are.
• To see the linker script, add the --verbose option. Look for the SEARCH_DIR("...") directives, usually near the top of the output. (Note that these are not necessarily the same for every invocation of ld -- the linker has a number of different built-in default linker scripts, and chooses between them based on various other linker options.)

If you're linking via gcc:

• You can pass the -v option to gcc so that it shows you how it invokes the linker. In fact, it normally does not invoke ld directly, but indirectly via a tool called collect2 (which lives in one of its internal directories), which in turn invokes ld. That will show you what -L options are being used.
• You can add -Wl,--verbose to the gcc options to make it pass --verbose through to the linker, to see the linker script as described above.

Best way that I found:

function isEmpty(obj)
{
    if (!obj)
    {
        return true;
    }

    if (!(typeof(obj) === 'number') && !Object.keys(obj).length)
    {
        return true;
    }

    return false;
}

Works for:

    t1: {} -> true
    t2: {0:1} -: false
    t3: [] -> true
    t4: [2] -> false
    t5: null -> true
    t6: undefined -> true
    t7: "" -> true
    t8: "a" -> false
    t9: 0 -> true
    t10: 1 -> false

A modification of the accepted answer above, which also detects the MIME type in runtime:

$finfo = finfo_open(FILEINFO_MIME_TYPE);
header('Content-Type: '.finfo_file($finfo, $path));

$finfo = finfo_open(FILEINFO_MIME_ENCODING);
header('Content-Transfer-Encoding: '.finfo_file($finfo, $path)); 

header('Content-disposition: attachment; filename="'.basename($path).'"'); 
readfile($path); // do the double-download-dance (dirty but worky)

For attached properties you can either call SetValue on the object for which you want to assign the value:

tblock.SetValue(Grid.RowProperty, 4);

Or call the static Set method (not as an instance method like you tried) for the property on the owner type, in this case SetRow:

Grid.SetRow(tblock, 4);

The best method for setting a socket as non-blocking in C is to use ioctl. An example where an accepted socket is set to non-blocking is following:

long on = 1L;
unsigned int len;
struct sockaddr_storage remoteAddress;
len = sizeof(remoteAddress);
int socket = accept(listenSocket, (struct sockaddr *)&remoteAddress, &len)
if (ioctl(socket, (int)FIONBIO, (char *)&on))
{
    printf("ioctl FIONBIO call failed\n");
}

Seems like an old question but still relevant.

I think it is a blocked update issue.

The main problem is the new URL (route) is supposed to be rendered by the same component(Costumers) as you are currently in (current URL).

So solution is rather simple, make the window url as a prop, so react has a chance to detect the prop change (therefore the url change), and act accordingly.

A nice usecase described in the official react blog called Recommendation: Fully uncontrolled component with a key.

So the solution is to change from render() { return( <ul>

to render() { return( <ul key={this.props.location.pathname}>

So whenever the location changed by react-router, the component got scrapped (by react) and a new one gets initiated with the right values (by react).

Oh, and pass the location as prop to the component(Costumers) where the redirect will happen if it is not passed already.

Hope it helps someone.

To get a random integer value between 1 and N (inclusive) you can use the following.

CInt(Math.Ceiling(Rnd() * n)) + 1

Most SSL certificates are bound to the hostname of the machine and not the ip address.

To call the camera you can use:

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivity(intent);

The image will be automatically saved in a default directory.

And you need to set the permission for the camera in your AndroidManifest.xml:

<uses-permission android:name="android.permission.CAMERA"> </uses-permission>

Just do this. It doesn't affect the horizontal position.

.test {
 position: fixed;
 left: 0;
 right: 0;
 }

I ran into the same problem using MySQL Workbench. According to the MySQL documentation, the DECLARE "statement declares local variables within stored programs." That apparently means it is only guaranteed to work with stored procedures/functions.

The solution for me was to simply remove the DECLARE statement, and introduce the variable in the SET statement. For your code that would mean:

-- DECLARE FOO varchar(7); 
-- DECLARE oldFOO varchar(7);

-- the @ symbol is required
SET @FOO = '138'; 
SET @oldFOO = CONCAT('0', FOO);

UPDATE mypermits SET person = FOO WHERE person = oldFOO;

You can force the case sensitive, casting to a varbinary like that:

SELECT * FROM myTable 
WHERE convert(varbinary, myField) = convert(varbinary, 'sOmeVal')

In JavaScript:

pageX, pageY, screenX, screenY, clientX, and clientY returns a number which indicates the number of physical “CSS pixels” a point is from the reference point. The event point is where the user clicked, the reference point is a point in the upper left. These properties return the horizontal and vertical distance from that reference point.

pageX and pageY:
Relative to the top left of the fully rendered content area in the browser. This reference point is below the URL bar and back button in the upper left. This point could be anywhere in the browser window and can actually change location if there are embedded scrollable pages embedded within pages and the user moves a scrollbar.

screenX and screenY:
Relative to the top left of the physical screen/monitor, this reference point only moves if you increase or decrease the number of monitors or the monitor resolution.

clientX and clientY:
Relative to the upper left edge of the content area (the viewport) of the browser window. This point does not move even if the user moves a scrollbar from within the browser.

One thing I don't think has been mentioned in the previous answers.

I'm always sensing a "bad smell" in the refactoring sense when people are using such things in their design.

That's a huge array and possibly not the best way to represent your data both from an efficiency point of view and a performance point of view.

You should bind a function to keyup event

textarea.keyup = function(){
   textarea.value.length....
} 

with jquery

$('textarea').keyup(function(){
   var length = $(this).val().length;
});

Use paste.

 df$x <- paste(df$n,df$s)
 df
#   n  s     b    x
# 1 2 aa  TRUE 2 aa
# 2 3 bb FALSE 3 bb
# 3 5 cc  TRUE 5 cc

I would argue against "abstract" tests. I think a test is a concrete idea and doesn't have an abstraction. If you have common elements, put them in helper methods or classes for everyone to use.

As for testing an abstract test class, make sure you ask yourself what it is you're testing. There are several approaches, and you should find out what works in your scenario. Are you trying to test out a new method in your subclass? Then have your tests only interact with that method. Are you testing the methods in your base class? Then probably have a separate fixture only for that class, and test each method individually with as many tests as necessary.

looks like bad architecture all the way. also you have not specified the type of app you need to notify to (web app / console app / winforms / service etc etc)

nevertheless, to answer your question, there are multiple ways of solving this. you could use:

1) timestamps if you were just interested in ensuring the next set of updates from the second app dont conflict with the updates from the first app

2) sql dependency object - see http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldependency.aspx for more info

3) a custom push notification service which multiple clients (web / winform / service) can subscribe to and get notified on changes

in short, you need to use the simplest and easiest and cheapest (in terms of efforts) solution based on how complex your notification requirements are and for what purpose you need to use them. dont try to build an overly complex notification system if a simple data concurrency is your only requirement (in that case go for a simple timestamp based solution)

Pretty late, but you can also do this by annotating a @BeforeStep method:

@BeforeStep
    public void beforeStep(final StepExecution stepExecution) {
        JobParameters parameters = stepExecution.getJobExecution().getJobParameters();
        //use your parameters
}

Using [innerHTML] directly without using Angular's DOM sanitizer is not an option if it contains user-created content. The safeHtml pipe suggested by @GünterZöchbauer in his answer is one way of sanitizing the content. The following directive is another one:

import { Directive, ElementRef, Input, OnChanges, Sanitizer, SecurityContext,
  SimpleChanges } from '@angular/core';

// Sets the element's innerHTML to a sanitized version of [safeHtml]
@Directive({ selector: '[safeHtml]' })
export class HtmlDirective implements OnChanges {
  @Input() safeHtml: string;

  constructor(private elementRef: ElementRef, private sanitizer: Sanitizer) {}

  ngOnChanges(changes: SimpleChanges): any {
    if ('safeHtml' in changes) {
      this.elementRef.nativeElement.innerHTML =
        this.sanitizer.sanitize(SecurityContext.HTML, this.safeHtml);
    }
  }
}

To be used

<div [safeHtml]="myVal"></div>

I know this is like years old post but since there is no selected answer I hope this answer may give you what you are expecting...

if(document.getElementsByTagName){  
    var table = document.getElementById('table className');
    for (var i = 0, row; row = table.rows[i]; i++) {
    //rows would be accessed using the "row" variable assigned in the for loop
     for (var j = 0, col; col = row.cells[j]; j++) {
     //columns would be accessed using the "col" variable assigned in the for loop
        alert('col html>>'+col.innerHTML);    //Will give you the html content of the td
        alert('col>>'+col.innerText);    //Will give you the td value
        }
      }
    }
}

Can't you just count the rows using select count(*) from table (or an indexed column instead of * if speed is important)?

If not then maybe this article can point you in the right direction.

{"param1"=>["value1"], "param2"=>["value2"], "param3"=>["value3"]}

In general, pickling a dict will fail unless you have only simple objects in it, like strings and integers.

However, if you use a better serializer like dill or cloudpickle, then most dictionaries can be pickled:

>>> import dill
>>> pik = dill.dumps(d)

Or if you want to save your dict to a file...

>>> with open('save.pik', 'w') as f:
...   dill.dump(globals(), f)
... 

The latter example is identical to any of the other good answers posted here (which aside from neglecting the picklability of the contents of the dict are good).

line = line.Replace("\\", "");

There are several problems here:

1. The newdata argument of predict() needs a predictor variable. You should thus pass it values for Coupon, instead of Total, which is the response variable in your model.

2. The predictor variable needs to be passed in as a named column in a data frame, so that predict() knows what the numbers its been handed represent. (The need for this becomes clear when you consider more complicated models, having more than one predictor variable).

3. For this to work, your original call should pass df in through the data argument, rather than using it directly in your formula. (This way, the name of the column in newdata will be able to match the name on the RHS of the formula).

With those changes incorporated, this will work:

model <- lm(Total ~ Coupon, data=df)
new <- data.frame(Coupon = df$Coupon)
predict(model, newdata = new, interval="confidence")

Very basic, but does what you need without any addon modules or PS version requirements:

while ($true) {Clear-Host; gc E:\test.txt | select -last 3; sleep 2 }

The only way to do that with pure javascript is to implement some kind of polling mechanism. You will need to send ajax requests at fixed intervals (each 5 seconds for example) to get the number of bytes received by the server.

A more efficient way would be to use flash. The flex component FileReference dispatchs periodically a 'progress' event holding the number of bytes already uploaded. If you need to stick with javascript, bridges are available between actionscript and javascript. The good news is that this work has been already done for you :)

swfupload

This library allows to register a javascript handler on the flash progress event.

This solution has the hudge advantage of not requiring aditionnal resources on the server side.

String str = "   Text    with    multiple    spaces    ";
str = org.apache.commons.lang3.StringUtils.normalizeSpace(str);
// str = "Text with multiple spaces"

You can put an equal formula, then copy it so reference the whole range (one cell goes into one cell)

=Sheet2!A1

If you need to concatenate the results, you'll need a longer formula, or a user-defined function (i.e. macro).

=Sheet2!A1&Sheet2!B1&Sheet2!C1&Sheet2!D1&Sheet2!E1&Sheet2!F1

If you want to list them all in a nice list but without using the cruddy non human friendly name, you can do this...

object.errors.each do |attr,message|
  puts "<li>"+message+"</li>"
end

In SQL Server 2008,2012,2014 you can insert multiple rows using a single SQL INSERT statement.

 INSERT INTO TableName ( Column1, Column2 ) VALUES
    ( Value1, Value2 ), ( Value1, Value2 )

Another way

INSERT INTO TableName (Column1, Column2 )
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2

Assuming Java (JDK + JRE) is installed in your system, do the following steps:

1. Install Tomcat7
2. Copy 'tools.jar' from 'C:\Program Files (x86)\Java\jdk1.6.0_27\lib' and paste it under 'C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\lib'.
3. Setup paths in your Environment Variables as shown below:

C:>echo %path%

C:\Program Files (x86)\Java\jdk1.6.0_27\bin;%CATALINA_HOME%\bin;

C:>echo %classpath%

C:\Program Files (x86)\Java\jdk1.6.0_27\lib\tools.jar;
C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\lib\servlet-api.jar;

C:>echo %CATALINA_HOME%

C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0;

C:>echo %JAVA_HOME%

C:\Program Files (x86)\Java\jdk1.6.0_27;

Now you can test whether Tomcat is setup correctly, by typing the following commands in your command prompt:

C:/>javap javax.servlet.ServletException
C:/>javap javax.servlet.http.HttpServletRequest

It should show a bunch of classes

Now start Tomcat service by double clicking on 'Tomcat7.exe' under 'C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\bin'.

in oracle you can use

desc users

to display all columns containing in users table

I accidentally had a value in the Client Secret part of the URL, but Google Credential does not need a Client Secret for Android OAuth 2 Client IDs. Simply leaving the value blank in the URL did the trick for me.

The Most simple code you can write:

    persons.stream().map(x-> x.getName()).distinct().collect(Collectors.toList());

For more detail

create .htaccess file on project root directory and put below code for remove index.php

  RewriteEngine on
  RewriteCond $1 !^(index.php|resources|robots.txt)
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php/$1 [L,QSA]

You have two versions of ADB

$ /usr/local/bin/adb version
Android Debug Bridge version 1.0.36
Revision 0e9850346394-android

and

$ /Users/user/Library/Android/sdk/platform-tools/adb version
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android

You could see which one your PATH is pointing to (echo $PATH) but I fixed it with a adb stop-server on one version and a adb start-server on the other.

Sure, simply bind multiple listeners to it.

Short cutting with jQuery

$("#id").bind("click", function() {_x000D_
  alert("Event 1");_x000D_
});_x000D_
$(".foo").bind("click", function() {_x000D_
  alert("Foo class");_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div class="foo" id="id">Click</div>

object["property"] = value;

or

object.property = value;

Object and Array in JavaScript are different in terms of usage. Its best if you understand them:

Object vs Array: JavaScript

Here is the code

<input type="button" value="Back" onclick="window.history.back()" /> 

Couple of commands are there to list all dbs in MongoDB shell.

first , launch Mongodb shell using 'mongo' command.

mongo

Then use any of the below commands to list all the DBs.

• show dbs
• show databases
• db.adminCommand( { listDatabases: 1 , nameOnly : true} )

For more details please check here

Thank you.

You can also do something like this ...

• First create and Initialize the matrix or multidimensional arraylist

  ArrayList<ArrayList<Integer>> list; MultidimentionalArrayList(int x,int y) { list = new ArrayList<>(); for(int i=0;i<=x;i++) { ArrayList<Integer> temp = new ArrayList<>(Collections.nCopies(y+1,0)); list.add(temp); } }

  • Add element at specific position void add(int row,int column,int val) { list.get(row).set(column,val); // list[row][column]=val }

  This static matrix can be change into dynamic if check that row and column are out of bound. just insert extra temp arraylist for row

  • remove element

  int remove(int row, int column) { return list.get(row).remove(column);// del list[row][column] }

In your CSS file:

input { margin-bottom: 10px; }

I've previously blindly followed the answer based on the MSDN docs. Today, this turned out to be less than required. On a machine with Office Home and Student installed, which doesn't include Outlook, HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\Outlook was present, but HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Outlook was not. I've now changed my code to first look for the "plain" non-Wow6432Node version. If that's present, it'll be used. If not, it will continue by looking at the Wow6432Node version. This is being checked in an Inno Setup-based installer - I don't know which APIs Inno Setup uses. If your app doesn't access the registry in the same way, you might see different results.

To get Token Device you can do by some steps:

1) Enable APNS (Apple Push Notification Service) for both Developer Certification and Distribute Certification, then redownload those two file.

2) Redownload both Developer Provisioning and Distribute Provisioning file.

3) In Xcode interface: setting provisioning for PROJECT and TARGETS with two file provisioning have download.

4) Finally, you need to add the code below in AppDelegate file to get Token Device (note: run app in real device).

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
     [self.window addSubview:viewController.view];
     [self.window makeKeyAndVisible];

     NSLog(@"Registering for push notifications...");    
     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
     return YES;
}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
     NSString *str = [NSString stringWithFormat:@"Device Token=%@",deviceToken];
     NSLog(@"%@", str);
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { 
     NSString *str = [NSString stringWithFormat: @"Error: %@", err];
     NSLog(@"%@",str);
}

The following Link has explained complete details about how to back sql server 2008 database using c#

Sql Database backup can be done using many way. You can either use Sql Commands like in the other answer or have create your own class to backup data.

But these are different mode of backup.

1. Full Database Backup
2. Differential Database Backup
3. Transaction Log Backup
4. Backup with Compression

But the disadvantage with this method is that it needs your sql management studio to be installed on your client system.

Use the following block of query to update Table1 with Table2 based on ID:

UPDATE Sales_Import, RetrieveAccountNumber 
SET Sales_Import.AccountNumber = RetrieveAccountNumber.AccountNumber 
where Sales_Import.LeadID = RetrieveAccountNumber.LeadID;

This is the easiest way to tackle this problem.

Short personal bookmarklet version

javascript: document.body.webkitRequestFullScreen(); 

go fullscreen ? You can drag this link to your bookmark bar to create the bookmarklet, but you have to edit its URL afterwards: Delete everything before javascript, including the single slash: http://delete_me/javascript:[…]

This works for me in Google Chrome. You have to test whether it works in your environment and otherwise use a different wording of the function call, e.g. javascript:document.body.requestFullScreen(); – see the other answers for the possible variants.

_{Based on the answers by @Zuul and @default – thanks!}

var x = '<option value="' + col + '"'
if (col == 'screwdriver') x += ' selected';
x += '>Very roomy</option>';

If you want to search a file for a substring and add a new text to the next line, one of the elegant ways to do it is the following:

import fileinput
for line in fileinput.FileInput(file_path,inplace=1):
    if "TEXT_TO_SEARCH" in line:
        line=line.replace(line,line+"NEW_TEXT")
    print line,

Make sure your ServerRoot in httpd.conf points correctly to the Apache path. Otherwise you will see this message for every further module.

Examples:

• /etc/apache2/apache2 for Linux
• "C:\Program Files\Apache24" for Windows

Adding my scenario and solution in case it helps someone else. I encountered similar case when using RESTful APIs. My Web server hosting HTML/Script/CSS files and Application Server exposing APIs were hosted on same domain. However the path was different.

web server - mydomain/webpages/abc.html

used abc.js which set cookie named mycookie

app server - mydomain/webapis/servicename.

to which api calls were made

I was expecting the cookie in mydomain/webapis/servicename and tried reading it but it was not being sent. After reading comment from the answer, I checked in browser's development tool that mycookie's path was set to "/webpages" and hence not available in service call to

mydomain/webapis/servicename

So While setting cookie from jquery, this is what I did -

$.cookie("mycookie","mayvalue",{**path:'/'**});

I'm using the code below. working

@Query(value = "select * from user usr" +
  "left join apl apl on usr.user_id = apl.id" +
  "left join lang on lang.role_id = usr.role_id" +
  "where apl.scr_name like %:scrname% and apl.uname like %:uname and usr.role_id in :roleIds ORDER BY ?#{#pageable}",
  countQuery = "select count(*) from user usr" +
      "left join apl apl on usr.user_id = apl.id" +
      "left join lang on lang.role_id = usr.role_id" +
      "where apl.scr_name like %:scrname% and apl.uname like %:uname and usr.role_id in :roleIds",
  nativeQuery = true)
Page<AplUserEntity> searchUser(@Param("scrname") String scrname,@Param("uname") String  uname,@Param("roleIds") List<Long> roleIds,Pageable pageable);

This was how I solved it:

mysql> DROP DATABASE mydatabase;
ERROR 1010 (HY000): Error dropping database (can't rmdir '.\mydatabase', errno: 13)
mysql> 

I went to delete this directory: C:\...\UniServerZ\core\mysql\data\mydatabase.

mysql> DROP DATABASE mydatabase;
ERROR 1008 (HY000): Can't drop database 'mydatabase'; database doesn't exist

HashSet<T> is what you're looking for. From MSDN (emphasis added):

The HashSet<T> class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order.

Note that the HashSet<T>.Add(T item) method returns a bool -- true if the item was added to the collection; false if the item was already present.

You can take a diff that undoes the changes you want and commit that.

E.g. If you want to undo the changes in the range from..to, do the following

git diff to..from > foo.diff  # get a reverse diff
patch < foo.diff
git commit -a -m "Undid changes from..to".

Is this what you're after?

I added :text-align:center to the div and image

Integer division occurs, then the result, which is an integer, is assigned as a float. If the result is less than 1 then it ends up as 0.

You'll want to cast the expressions to floats first before dividing, e.g.

float m = (float)(a.y - b.y) / (float)(a.x - b.x);

In the layout (app/design/frontend/your_theme/layout/default.xml):

<default>
    <cms_page> <!-- need to be redefined for your needs -->
        <reference name="content">
            <block type="cms/block" name="cms_newest_product" as="cms_newest_product">
                <action method="setBlockId"><block_id>newest_product</block_id></action>
            </block>
        </reference>
    </cms_page>
</default>

In your phtml template:

<?php echo $this->getChildHtml('newest_product'); ?>

Don't forget about cache cleaning.

I think it help.
