Quick review,

• DB - Define Byte. 8 bits
• DW - Define Word. Generally 2 bytes on a typical x86 32-bit system
• DD - Define double word. Generally 4 bytes on a typical x86 32-bit system

From x86 assembly tutorial,

The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.

Your num is 1 byte. Try declaring it with DD so that it becomes 4 bytes and matches with pop semantics.

It's 2016, and there's no clear way of how to do this? I was hoping for some copypasta. I'll have a go.

Design notes: I wanted to minimize memory usage, and therefore improve speed - so there is no copying/mutating of strings. I assume V8 (and other engines) can optimise this function.

//TODO: Performance testing
String.prototype.naturalIndexOf = function(needle) {
    //TODO: guard conditions here
    
    var haystack = this; //You can replace `haystack` for `this` below but I wan't to make the algorithm more readable for the answer
    var needleIndex = 0;
    var foundAt = 0;
    for (var haystackIndex = 0; haystackIndex < haystack.length; haystackIndex++) {
        var needleCode = needle.charCodeAt(needleIndex);
        if (needleCode >= 65 && needleCode <= 90) needleCode += 32; //ToLower. I could have made this a function, but hopefully inline is faster and terser
        var haystackCode = haystack.charCodeAt(haystackIndex);
        if (haystackCode >= 65 && haystackCode <= 90) haystackCode += 32; //ToLower. I could have made this a function, but hopefully inline is faster and terser
        
        //TODO: code to detect unicode characters and fallback to toLowerCase - when > 128?
        //if (needleCode > 128 || haystackCode > 128) return haystack.toLocaleLowerCase().indexOf(needle.toLocaleLowerCase();
        if (haystackCode !== needleCode)
        {
            foundAt = haystackIndex;
            needleIndex = 0; //Start again
        }
        else
            needleIndex++;
            
        if (needleIndex == needle.length)
            return foundAt;
    }
    
    return -1;
}

My reason for the name:

• Should have IndexOf in the name
• Don't add a suffix word - IndexOf refers to the following parameter. So prefix something instead.
• Don't use "caseInsensitive" prefix would be sooooo long
• "natural" is a good candidate, because default case sensitive comparisons are not natural to humans in the first place.

Why not...:

• toLowerCase() - potential repeated calls to toLowerCase on the same string.
• RegExp - awkward to search with variable. Even the RegExp object is awkward having to escape characters

Smoke tests have been explained here already and is simple. Regression tests come under integration tests.

Automated tests can be divided into just two.

Unit tests and integration tests (this is all that matters)

I would call use the phrase "long test" (LT) for all tests like integration tests, functional tests, regression tests, UI tests, etc. And unit tests as "short test".

An LT example could be, automatically loading a web page, logging in to the account and buying a book. If the test passes it is more likely to run on live site the same way(hence the 'better sleep' reference). Long = distance between web page (start) and database (end).

And this is a great article discussing the benefits of integration testing (long test) over unit testing.

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

If you want to keep python 3, you can follow these directions to create a python 2.7 environment, called py27.

Then you just need to activate py27:

$ conda activate py27

Then you can install spyder on this environment, e.g.:

$ conda install spyder

Then you can start spyder from the command line or navigate to 2.7 version of spyder.exe below the envs directory (e.g. C:\ProgramData\Anaconda3\envs\py27\Scripts)

The file is a gzipped (compressed) SQL file, almost certainly a plain text file with .sql as its extension. The first thing you need to do is copy the file to your database server via scp.. I think PuTTY's is pscp.exe

# Copy it to the server via pscp
C:\> pscp.exe numbers.sql.gz user@serverhostname:/home/user

Then SSH into your server and uncompress the file with gunzip

user@serverhostname$  gunzip numbers.sql.gz
user@serverhostname$  ls 

numbers.sql

Finally, import it into your MySQL database using the < input redirection operator:

user@serverhostname$  mysql -u mysqluser -p < numbers.sql

If the numbers.sql file doesn't create a database but expects one to be present already, you will need to include the database in the command as well:

user@serverhostname$  mysql -u mysqluser -p databasename < numbers.sql

If you have the ability to connect directly to your MySQL server from outside, then you could use a local MySQL client instead of having to copy and SSH. In that case, you would just need a utility that can decompress .gz files on Windows. I believe 7zip does so, or you can obtain the gzip/gunzip binaries for Windows.

Include the port number with the IP address.

For example:

http://19.18.20.101:5566

where 5566 is the port number.

I had a similar problem with an SEHException that was thrown when my program first used a native dll wrapper. Turned out that the native DLL for that wrapper was missing. The exception was in no way helpful in solving this. What did help in the end was running procmon in the background and checking if there were any errors when loading all the necessary DLLs.

I'd just add that you don't need to implement a controller method for that as you can use the view-controller tag (Spring 3) in the servlet configuration file:

<mvc:view-controller path="/" view-name="/WEB-INF/jsp/index.html"/>

An absolutely positioned element is actually positioned regarding a relative parent, or the nearest found relative parent. So the element with overflow: hidden should be between relative and absolute positioned elements:

<div class="relative-parent">
  <div class="hiding-parent">
    <div class="child"></div>
  </div>
</div>

.relative-parent {
  position:relative;
}
.hiding-parent {
  overflow:hidden;
}
.child {
  position:absolute; 
}

Just if anyone is using Google Closure Library:

goog.require('goog.object');
var a = {'a': 1, 'b': 2};
var b = {'b': 3, 'c': 4};
goog.object.extend(a, b);
// Now object a == {'a': 1, 'b': 3, 'c': 4};

Similar helper function exists for array:

var a = [1, 2];
var b = [3, 4];
goog.array.extend(a, b); // Extends array 'a'
goog.array.concat(a, b); // Returns concatenation of array 'a' and 'b'

This is what solved my problem. ^M is a carriage return, and it can be easily avoided in a Perl script.

while(<INPUTFILE>)
{
     chomp;
     chop($_) if ($_ =~ m/\r$/);
}

Try using this:

If you specify ON DUPLICATE KEY UPDATE, and a row is inserted that would cause a duplicate value in a UNIQUE index orPRIMARY KEY, MySQL performs an [UPDATE`](http://dev.mysql.com/doc/refman/5.7/en/update.html) of the old row...

The ON DUPLICATE KEY UPDATE clause can contain multiple column assignments, separated by commas.

With ON DUPLICATE KEY UPDATE, the affected-rows value per row is 1 if the row is inserted as a new row, 2 if an existing row is updated, and 0 if an existing row is set to its current values. If you specify the CLIENT_FOUND_ROWS flag to mysql_real_connect() when connecting to mysqld, the affected-rows value is 1 (not 0) if an existing row is set to its current values...

The following format works in all browsers:

new Date("2010/08/17 12:09:36");

So, to make a yyyy-mm-dd hh:mm:ss formatted date string fully browser compatible you would have to replace dashes with slashes:

var dateString = "2010-08-17 12:09:36";
new Date(dateString.replace(/-/g, "/"));

here 'test/api/controllers/test.js' is filepath.

XSDs constrain the vocabulary and structure of XML documents.

• Without an XSD, an XML document need only follow the rules for being well-formed as given in the W3C XML Recommendation.
• With an XSD, an XML document must adhere to additional constraints placed upon the names and values of its elements and attributes in order to be considered valid against the XSD per the W3C XML Schema Recommendation.

XML is all about agreement, and XSDs provide the means for structuring and communicating the agreement beyond the basic definition of XML itself.

Just go to your Manifest file. and You have define the label for each activity in your manifest file.

<activity
        android:name=".Search_Video"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
    </activity>

here change

android:label="@string/your_title"

From my limited experience, this happens for two main reasons:

1. The lookup_value (arg1) is not present in the table_array (arg2)

The simple solution here is to use an error handler ending with Resume Next

2. The formats of arg1 and arg2 are not interpreted correctly

If your lookup_value is a variable you can enclose it with TRIM()

cellNum = wsFunc.VLookup(TRIM(currName), rngLook, 13, False)

1. you should use mysql command. It's a command line client for mysql RDBMS, and comes with most mysql installations: http://dev.mysql.com/doc/refman/5.1/en/mysql.html

2. To stop or start mysql database (you rarely should need doing that 'by hand'), use proper init script with stop or start parameter, usually /etc/init.d/mysql stop. This, however depends on your linux distribution. Some new distributions encourage service mysql start style.

3. You're logging in by using mysql sql shell.

4. The error comes probably because double '-p' parameter. You can provide -ppassword or just -p and you'll be asked for password interactively. Also note, that some instalations might use mysql (not root) user as an administrative user. Check your sqlyog configuration to obtain working connection parameters.

Making a small adjustment to Tor Valamo's solution to fix the problem noticed by Dominic Rodger, you could use:

// Remove anything which isn't a word, whitespace, number
// or any of the following caracters -_~,;[]().
// If you don't need to handle multi-byte characters
// you can use preg_replace rather than mb_ereg_replace
// Thanks @Lukasz Rysiak!
$file = mb_ereg_replace("([^\w\s\d\-_~,;\[\]\(\).])", '', $file);
// Remove any runs of periods (thanks falstro!)
$file = mb_ereg_replace("([\.]{2,})", '', $file);

From the documentation:

import gzip
f = gzip.open('file.txt.gz', 'rb')
file_content = f.read()
f.close()

Try this:

int main() {
  double num = 23.345;
  int intpart = (int)num;
  double decpart = num - intpart;
  printf("Num = %f, intpart = %d, decpart = %f\n", num, intpart, decpart);
}

For me, it produces:

Num = 23.345000, intpart = 23, decpart = 0.345000

Which appears to be what you're asking for.

Just found a proper working solution for other guys,

// Returns true or false based on the radio button checked_x000D_
$('#test1').prop('checked')_x000D_
_x000D_
_x000D_
$('body').on('change','input[type="radio"]',function () {_x000D_
alert('Test1 checked = ' + $('#test1').prop('checked') + '. Test2 checked = ' + $('#test2').prop('checked') + '. Test3 checked = ' + $('#test3').prop('checked'));_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="radio" runat="server" name="testGroup" id="test1" /><label for="<%=test1.ClientID %>" style="cursor:hand" runat="server">Test1</label>_x000D_
_x000D_
<input type="radio" runat="server" name="testGroup" id="test2" /><label for="<%=test2.ClientID %>" style="cursor:hand" runat="server">Test2</label>_x000D_
_x000D_
<input type="radio" runat="server" name="testGroup" id="test3" /> <label for="<%=test3.ClientID %>" style="cursor:hand">Test3</label>

and in your method you can use like

return $('#test2').prop('checked');

Pass it in through the constructor:

const char* dat = "my string!";
std::string my_string( dat );

You can use the function string.c_str() to go the other way:

std::string my_string("testing!");
const char* dat = my_string.c_str();

jsFiddle Demo

div {
    width: 250px;
    height: 250px;
    overflow: hidden;
    margin: 10px;
    position: relative;
}
img {
    position: absolute;
    left: -1000%;
    right: -1000%;
    top: -1000%;
    bottom: -1000%;
    margin: auto;

    min-width: 100%;
}

<div>
    <img src="https://i.postimg.cc/TwFrQXrP/plus-2.jpg" />
</div>

A note regarding sizes

As Salman A mentioned in the comments, we need to set the img's position coordinates (top, left, bottom, right) to work with percents higher than the image's actual dimensions. I use 1000% in the above example, but of course you can adjust it according to your needs.

* Further explanation: When we set the img's left and right (or: top and bottom) coordinates to be -100% (of the containing div), the overall allowed width (or: height) of the img, can be at most 300% of the containing div's width (or: height), because it's the sum of the div's width (or: height) and the left and right (or: top and bottom) coordinates.

Python 3 handles strings a bit different. Originally there was just one type for strings: str. When unicode gained traction in the '90s the new unicode type was added to handle Unicode without breaking pre-existing code¹. This is effectively the same as str but with multibyte support.

In Python 3 there are two different types:

• The bytes type. This is just a sequence of bytes, Python doesn't know anything about how to interpret this as characters.
• The str type. This is also a sequence of bytes, but Python knows how to interpret those bytes as characters.
• The separate unicode type was dropped. str now supports unicode.

In Python 2 implicitly assuming an encoding could cause a lot of problems; you could end up using the wrong encoding, or the data may not have an encoding at all (e.g. it’s a PNG image).
Explicitly telling Python which encoding to use (or explicitly telling it to guess) is often a lot better and much more in line with the "Python philosophy" of "explicit is better than implicit".

This change is incompatible with Python 2 as many return values have changed, leading to subtle problems like this one; it's probably the main reason why Python 3 adoption has been so slow. Since Python doesn't have static typing² it's impossible to change this automatically with a script (such as the bundled 2to3).

• You can convert str to bytes with bytes('h€llo', 'utf-8'); this should produce b'H\xe2\x82\xacllo'. Note how one character was converted to three bytes.
• You can convert bytes to str with b'H\xe2\x82\xacllo'.decode('utf-8').

Of course, UTF-8 may not be the correct character set in your case, so be sure to use the correct one.

In your specific piece of code, nextline is of type bytes, not str, reading stdout and stdin from subprocess changed in Python 3 from str to bytes. This is because Python can't be sure which encoding this uses. It probably uses the same as sys.stdin.encoding (the encoding of your system), but it can't be sure.

You need to replace:

sys.stdout.write(nextline)

with:

sys.stdout.write(nextline.decode('utf-8'))

or maybe:

sys.stdout.write(nextline.decode(sys.stdout.encoding))

You will also need to modify if nextline == '' to if nextline == b'' since:

>>> '' == b''
False

Also see the Python 3 ChangeLog, PEP 358, and PEP 3112.

¹ There are some neat tricks you can do with ASCII that you can't do with multibyte character sets; the most famous example is the "xor with space to switch case" (e.g. chr(ord('a') ^ ord(' ')) == 'A') and "set 6th bit to make a control character" (e.g. ord('\t') + ord('@') == ord('I')). ASCII was designed in a time when manipulating individual bits was an operation with a non-negligible performance impact.

² Yes, you can use function annotations, but it's a comparatively new feature and little used.

if you want to use truncate use this:

SET FOREIGN_KEY_CHECKS = 0; 
TRUNCATE table $table_name; 
SET FOREIGN_KEY_CHECKS = 1;

Before your </form> tag put:

{{ form_rest(form) }}

It will automatically insert other important (hidden) inputs.

<button my-directive="push">Push to Go</button>

app.directive("myDirective", function() {
    return {
        restrict : "A",
         link: function(scope, elm, attrs) {
                elm.bind('click', function(event) {

                    alert("You pressed button: " + event.target.getAttribute('my-directive'));
                });
        }
    };
});

here is what I did

I'm using directive as html attribute and I passed parameter as following in my HTML file. my-directive="push" And from the directive I retrieved it from the Mouse-click event object. event.target.getAttribute('my-directive').

<ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

 protected void MyButtonClick(object sender, System.EventArgs e)
{
     //Get the button that raised the event
Button btn = (Button)sender;

    //Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

Building on Rene's answer, you could also write a function that returned either TRUE if the substring was present, or FALSE if it wasn't:

Public Function Contains(strBaseString As String, strSearchTerm As String) As Boolean
'Purpose: Returns TRUE if one string exists within another
On Error GoTo ErrorMessage
    Contains = InStr(strBaseString, strSearchTerm)
Exit Function
ErrorMessage:
MsgBox "The database has generated an error. Please contact the database administrator, quoting the following error message: '" & Err.Description & "'", vbCritical, "Database Error"
End
End Function

$total_ratings is an array.

SQL Server 2008 databases are version 655. SQL Server 2008 R2 databases are 661. You are trying to attach an 2008 R2 database (v. 661) to an 2008 instance and this is not supported. Once the database has been upgraded to an 2008 R2 version, it cannot be downgraded. You'll have to either upgrade your 2008 SP2 instance to R2, or you have to copy out the data in that database into an 2008 database (eg using the data migration wizard, or something equivalent).

The message is misleading, to say the least, it says 662 because SQL Server 2008 SP2 does support 662 as a database version, this is when 15000 partitions are enabled in the database, see Support for 15000 Partitions.docx. Enabling the support bumps the DB version to 662, disabling it moves it back to 655. But SQL Server 2008 SP2 does not support 661 (the R2 version).

You have configured the auth.php and used members table for authentication but there is no user_email field in the members table so, Laravel says

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_email' in 'where clause' (SQL: select * from members where user_email = ? limit 1) (Bindings: array ( 0 => '[email protected]', ))

Because, it tries to match the user_email in the members table and it's not there. According to your auth configuration, laravel is using members table for authentication not users table.

If you have an Instance of the EditText available at the point in your code where you want add whitespace, then this code below will work. There may be some things to consider, for example the code below may trigger any TextWatcher you have set to this EditText, idk for sure, just saying, but this will work when trying to append blank space like this: " ", hasn't worked.

messageInputBox.dispatchKeyEvent(new KeyEvent(0, 0, 0, KeyEvent.KEYCODE_SPACE, 0, 0, 0, 0,
                        KeyEvent.KEYCODE_ENDCALL));

Try to replace this:

myLongList.ItemsSource = writings;

with this

Dispatcher.BeginInvoke(() => myLongList.ItemsSource = writings);

I don't think you can use fractional seconds with to_date or the DATE type in Oracle. I think you need to_timestamp which returns a TIMESTAMP type.

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

You have declared a function as nonstatic in some file and you have implemented as static in another file or somewhere in the same file can cause this problem also. For example, the following code will produce this error.

void inlet_update_my_ratio(object_t *myobject);
//some where the implementation is like this
static void inlet_update_my_ratio(object_t *myobject) {
//code
}

If you remove the static from the implementation, the error will go away as below.

 void inlet_update_my_ratio(object_t *myobject) {
    //code
    }

Your .htaccess should run just fine; it depends on four different Apache modules (one per each <IfModule> directive). I guess one of the following:

• your Apache server doesn't have either mod_filter, mod_deflate, mod_headers and/or mod_setenvif modules installed and running. If you can access the server config, please check /etc/apache2/httpd.conf (and the related Apache config files); otherwise, you can see which modules are loaded via phpinfo(), under the apache2handler section (see attached image); (EDIT) OR, you can open a terminal window and issue the command sudo apachectl -M that will list the loaded modules;

• if you get an http 500 internal server error, your server may not be allowed to use .htaccess files;

• you are trying to load a PHP file that sends its own headers (overwriting Apache'sheaders), thus "confusing" the browser.

In any case, you should double-check your server config and error logs to see what's going wrong. Just to be sure, try to use the fastest way suggested here in Apache docs:

AddOutputFilterByType DEFLATE text/html text/plain text/xml

and then try to load a large textfile (preferably, clean your cache first).

(EDIT) If the needed modules are there (in the Apache modules dir) but aren't loaded, just edit /etc/apache2/httpd.conf and add a LoadModule directive for each one of them.

If the needed modules aren't there (neither loaded, nor in the Apache modules directory), I fear that the only option is reinstalling Apache (a complete version).

## 2          (0:5e+05) * 2          100   0.587  3.536145     0.344    0.244
## 1     seq(0, 1e6, by = 2)         100   2.760 16.626506     1.832    0.900
## 3 seq.int(0, 1e6, by = 2)         100   0.166  1.000000     0.056    0.096

In this case, seq.int is the fastest method and seq the slowest. If performance of this step isn't that important (it still takes < 3 seconds to generate a sequence of 500,000 values), I might still use seq as the most readable solution.

You can't do it in a switch unless you're doing full string matching; that's doing substring matching. (This isn't quite true, as Sean points out in the comments. See note at the end.)

If you're happy that your regex at the top is stripping away everything that you don't want to compare in your match, you don't need a substring match, and could do:

switch (base_url_string) {
    case "xxx.local":
        // Blah
        break;
    case "xxx.dev.yyy.com":
        // Blah
        break;
}

...but again, that only works if that's the complete string you're matching. It would fail if base_url_string were, say, "yyy.xxx.local" whereas your current code would match that in the "xxx.local" branch.

Update: Okay, so technically you can use a switch for substring matching, but I wouldn't recommend it in most situations. Here's how (live example):

function test(str) {
    switch (true) {
      case /xyz/.test(str):
        display("• Matched 'xyz' test");
        break;
      case /test/.test(str):
        display("• Matched 'test' test");
        break;
      case /ing/.test(str):
        display("• Matched 'ing' test");
        break;
      default:
        display("• Didn't match any test");
        break;
    }
}

That works because of the way JavaScript switch statements work, in particular two key aspects: First, that the cases are considered in source text order, and second that the selector expressions (the bits after the keyword case) are expressions that are evaluated as that case is evaluated (not constants as in some other languages). So since our test expression is true, the first case expression that results in true will be the one that gets used.

On MAC OS X Leopard and higher

cd /etc/paths.d

There may be a text file in the above directory that contains the path you are trying to remove.

vim textfile //check and see what is in it when you are done looking type :q 
//:q just quits, no saves

If its the one you want to remove do this

rm textfile //remove it, delete it

Here is a link to a site that has more info on it, even though it illustrates 'adding' the path. However, you may gain some insight.

You need to have a container for your content div that you wish to be 100% - 100px

#container {
   width: 100%
}
#content {
   margin-right:100px;
   width:100%;
}

<div id="container">
  <div id="content">
      Your content here
  </div>
</div>

You might need to add a clearing div just before the last </div> if your content div is overflowing.

<div style="clear:both; height:1px; line-height:0">&nbsp;</div>

React + TypeScript inline util method:

const navigateToExternalUrl = (url: string, shouldOpenNewTab: boolean = true) =>
shouldOpenNewTab ? window.open(url, "_blank") : window.location.href = url;

Try this:

 git fetch --all
 git reset --hard origin/master

Explanation:

git fetch downloads the latest from remote without trying to merge or rebase anything.

Please let me know if you have any questions!

I think it is best way for you.

You should add this: this.onTodoChange = this.onTodoChange.bind(this).

And your function has event param(e), and get value:

componentWillMount(){
        this.setState({
            updatable : false,
            name : this.props.name,
            status : this.props.status
        });
    this.onTodoChange = this.onTodoChange.bind(this)
    }
    
    
<input className="form-control" type="text" value={this.state.name} id={'todoName' + this.props.id} onChange={this.onTodoChange}/>

onTodoChange(e){
         const {name, value} = e.target;
        this.setState({[name]: value});
   
}

This is slightly an edge case but I think it can add some value to the other answers.

If you add more details to the graph (say an annotation or a line) you'll soon discover that it is relevant when you call legend on the axis: if you call it at the bottom of the script it will capture different handles for the legend elements, messing everything.

For instance the following script:

df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
ax = df.plot(kind='bar')
ax.hlines(23, -.5,.5, linestyles='dashed')
ax.annotate('average',(-0.4,23.5))

ax.legend(["AAA", "BBB"]); #quickfix: move this at the third line

Will give you this figure, which is wrong:

While this a toy example which can be easily fixed by changing the order of the commands, sometimes you'll need to modify the legend after several operations and hence the next method will give you more flexibility. Here for instance I've also changed the fontsize and position of the legend:

df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
ax = df.plot(kind='bar')
ax.hlines(23, -.5,.5, linestyles='dashed')
ax.annotate('average',(-0.4,23.5))
ax.legend(["AAA", "BBB"]);

# do potentially more stuff here

h,l = ax.get_legend_handles_labels()
ax.legend(h[:2],["AAA", "BBB"], loc=3, fontsize=12)

This is what you'll get:

.toggleClass() will not animate, you should go for slideToggle() or .animate() method.

Even user has got answer and @Michael - sqlbot has covered mostly points very well in his post but one point is missing, so just trying to cover it.

If you want to provide read permission to a simple user (Not admin kind of)-

GRANT SELECT, EXECUTE ON DB_NAME.* TO 'user'@'localhost' IDENTIFIED BY 'PASSWORD';

Note: EXECUTE is required here, so that user can read data if there is a stored procedure which produce a report (have few select statements).

Replace localhost with specific IP from which user will connect to DB.

Additional Read Permissions are-

• SHOW VIEW : If you want to show view schema.
• REPLICATION CLIENT : If user need to check replication/slave status. But need to give permission on all DB.
• PROCESS : If user need to check running process. Will work with all DB only.

Suppose STUDENTID contains some characters or numbers that you already know i.e. 'searchstring' then below query will work for you.

You could try this:

select * from STUDENTS where CHARINDEX('searchstring',STUDENTID)>0

I think this one is the fastest and easiest one.

function LoadCategories() {
    var data = [];
    var url = '@Url.Action("GetCategories", "InternalTables")';
    $.getJSON(url, null, function (data) {
        data = $.map(data, function (item, a) {
            return "<option value=" + item.Value + ">" + item.Description + "</option>";
        });
        $("#ddlCategory").html('<option value="0">Select</option>');
        $("#ddlCategory").append(data.join(""));
    });
}

The question mentions Windows, and the accepted answer also works for Ubuntu, but for those who found this question coming from a Redhat flavor of Linux, this did the trick:

sudo yum install -y python-setuptools

you can use valign="top" on the td tag it is working perfectly for me.

Copy and paste the following into a new .htaccess file and place it on your website's root folder :

php_flag  display_errors                  on
php_flag  display_startup_errors          on

Errors will be shown directly in your page.

That's the best way to debug quickly but don't use it for long time because it could be a security breach.

Here it is

 <script>
          $(function () {
              var date = new Date();
              date.setDate(date.getDate() - 7);

            $('#datetimepicker1').datetimepicker({
                maxDate: 'now',
                showTodayButton: true,
                showClear: true,
                minDate: date
            });
        });
    </script>

I tried the code posted by larsmans above but, there are a couple of problems:

1) The code as is will throw the error as mentioned by mauguerra 2) If you change the code to the following:

...
    d1 = d1.strftime("%Y-%m-%d")
    d2 = d2.strftime("%Y-%m-%d")
    return abs((d2 - d1).days)

This will convert your datetime objects to strings but, two things

1) Trying to do d2 - d1 will fail as you cannot use the minus operator on strings and 2) If you read the first line of the above answer it stated, you want to use the - operator on two datetime objects but, you just converted them to strings

What I found is that you literally only need the following:

import datetime

end_date = datetime.datetime.utcnow()
start_date = end_date - datetime.timedelta(days=8)
difference_in_days = abs((end_date - start_date).days)

print difference_in_days

I think you can simply change the query to return boolean as

@Query("select count(e)>0 from MyEntity e where ...")

PS: If you are checking exists based on Primary key value CrudRepository already have exists(id) method.

The easiest of all:

keytool -list -printcert -jarfile file.apk

This uses the Java built-in keytool app and does not require extraction or any build-tools installation.

Suppose your project has the following structure and you want to do imports in the notebook.ipynb:

/app
  /mypackage
    mymodule.py
  /notebooks
    notebook.ipynb

If you are running Jupyter inside a docker container without any virtualenv it might be useful to create Jupyter (ipython) config in your project folder:

/app
  /profile_default
    ipython_config.py

Content of ipython_config.py:

c.InteractiveShellApp.exec_lines = [
    'import sys; sys.path.append("/app")'
]

Open the notebook and check it out:

print(sys.path)

['', '/usr/local/lib/python36.zip', '/usr/local/lib/python3.6', '/usr/local/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages/IPython/extensions', '/root/.ipython', '/app']

Now you can do imports in your notebook without any sys.path appending in the cells:

from mypackage.mymodule import myfunc

In the majority of project there are some implementation of object extending: underscore, jquery, lodash: extend.

There is also pure javascript implementation, that is a part of ECMAscript 6: Object.assign: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign

public class ImageTransformation {

public static final String PNG = "png";

public static byte[] resize(FileItem fileItem, int width, int height) {

    try {
        ResampleOp resampleOp = new ResampleOp(width, height);
        BufferedImage scaledImage = resampleOp.filter(ImageIO.read(fileItem.getInputStream()), null);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        ImageIO.write(scaledImage, PNG, baos);

        return baos.toByteArray();
    } catch (Exception ex) {
        throw new MapsException("An error occured during image resizing.", ex);
    }

}

public static byte[] resizeAdjustMax(FileItem fileItem, int maxWidth, int maxHeight) {

    try {
        BufferedInputStream bis = new BufferedInputStream(fileItem.getInputStream());  
        BufferedImage bufimg = ImageIO.read(bis);   

        //check size of image 
        int img_width = bufimg.getWidth();
        int img_height = bufimg.getHeight();
        if(img_width > maxWidth || img_height > maxHeight) {
            float factx = (float) img_width / maxWidth;
            float facty = (float) img_height / maxHeight;
            float fact = (factx>facty) ? factx : facty;
            img_width = (int) ((int) img_width / fact);
            img_height = (int) ((int) img_height / fact);
        }

        return resize(fileItem,img_width, img_height);

    } catch (Exception ex) {
        throw new MapsException("An error occured during image resizing.", ex);
    }

}

}

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

I had a similar problem, but I had the existing id, and as egiray said, I was calling DOM before it loaded and Javascript console was showing the same error, so I tried:

window.onload = (function(){myfuncname()});

and it starts working.

This is default by iOS7 design. try to do the below:

[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];

You can set the 'Separator Inset' from the storyboard:

Go to Start > Programs > Microsoft SQL Server > Enterprise Manager

Right-click the SQL Server instance name > Select Properties from the context menu > Select Security node in left navigation bar

Under Authentication section, select SQL Server and Windows Authentication

Note: The server must be stopped and re-started before this will take effect

Error 18452 (not associated with a trusted sql server connection)

For one, you can wrap it up in a function:

function manytimes {
    n=0
    times=$1
    shift
    while [[ $n -lt $times ]]; do
        $@
        n=$((n+1))
    done
}

Call it like:

$ manytimes 3 echo "test" | tr 'e' 'E'
tEst
tEst
tEst

All you need to do is configure your SSH setup with multiple SSH keypairs.

• This link is easy to follow (Thanks Eric): http://code.tutsplus.com/tutorials/quick-tip-how-to-work-with-github-and-multiple-accounts--net-22574

• Generating SSH keys (Win/msysgit) https://help.github.com/articles/generating-an-ssh-key/

Also, if you're working with multiple repositories using different personas, you need to make sure that your individual repositories have the user settings overridden accordingly:

Setting user name, email and GitHub token – Overriding settings for individual repos https://help.github.com/articles/setting-your-commit-email-address-in-git/

Hope this helps.

Note: Some of you may require different emails to be used for different repositories, from git 2.13 you can set the email on a directory basis by editing the global config file found at: ~/.gitconfig using conditionals like so:

[user]
    name = Pavan Kataria
    email = [email protected]

[includeIf "gitdir:~/work/"]
    path = ~/work/.gitconfig

And then your work specific config ~/work/.gitconfig would look like this:

[user]
    email = [email protected]

Thank you @alexg for informing me of this in the comments.

Here other solution to only unlock the blocked user. From your command prompt log as SYSDBA:

sqlplus "/ as sysdba"

Then type the following command:

alter user <your_username> account unlock;

We can also define it using global in setupTests

// setupTests.js
global.open = jest.fn()

And call it using global in the actual test:

// yourtest.test.js
it('correct url is called', () => {
    statementService.openStatementsReport(111);
    expect(global.open).toBeCalled();
});

Starting with the observation that we can retrieve the ids of a table (eg. count 5) based on a set:

select *
from table_name
where _id in (4, 1, 2, 5, 3)

we can come to the result that if we could generate the string "(4, 1, 2, 5, 3)", then we would have a more efficient way than RAND().

For example, in Java:

ArrayList<Integer> indices = new ArrayList<Integer>(rowsCount);
for (int i = 0; i < rowsCount; i++) {
    indices.add(i);
}
Collections.shuffle(indices);
String inClause = indices.toString().replace('[', '(').replace(']', ')');

If ids have gaps, then the initial arraylist indices is the result of an sql query on ids.

For those without LINQ:

RadioButton GetCheckedRadio(Control container)
{
    foreach (var control in container.Controls)
    {
        RadioButton radio = control as RadioButton;

        if (radio != null && radio.Checked)
        {
            return radio;
        }
    }

    return null;
}

What about GLM?

It's based on the OpenGL Shading Language (GLSL) specification and released under the MIT license. Clearly aimed at graphics programmers

This worked for me (as of Angular 2.1.0):

constructor(private route: ActivatedRoute) {}
ngOnInit() {
  // Capture the token  if available
  this.sessionId = this.route.snapshot.queryParams['token']

}

My preference:

find . -name '*.jpg' -o -name '*.png' -print | grep Robert

Just Add:

android:screenOrientation="portrait"

in "AndroidManifest.xml" :

<activity
android:screenOrientation="portrait"
android:name=".MainActivity"
android:label="@string/app_name">
</activity>

According to the HTML specification you can't access the elements of the Canvas. You can get its context, and draw in it manipulate it, but that is all.

BUT, you can put both the Canvas and the html element in the same div with a aposition: relative and then set the canvas and the other element to position: absolute. This ways they will be on the top of each other. Then you can use the left and right CSS properties to position the html element.

If the element doesn't shows up, maybe the canvas is before it, so use the z-index CSS property to bring it before the canvas.

In order to change the data source from the ribbon in excel 2007...

Click on your pivot table in the worksheet. Go to the ribbon where it says Pivot Table Tools, Options Tab. Select the Change Data Source button. A dialog box will appear.

To get the right range and avoid an error message... select the contents of the existing field and delete it, then switch to the new data source worksheet and highlight the data area (the dialog box will stay on top of all windows). Once you've selected the new data source correctly, it will fill in the blank field (which you deleted before) in the dialog box. Click OK. Switch back to your pivot table and it should have updated with the new data from the new source.

I found this SQL statement to be a useful place to start (sorry I can't attribute this to the original author; I found it somewhere on the internet):

SELECT * FROM
(SELECT
    sql_fulltext,
    sql_id,
    elapsed_time,
    child_number,
    disk_reads,
    executions,
    first_load_time,
    last_load_time
FROM    v$sql
ORDER BY elapsed_time DESC)
WHERE ROWNUM < 10
/

This finds the top SQL statements that are currently stored in the SQL cache ordered by elapsed time. Statements will disappear from the cache over time, so it might be no good trying to diagnose last night's batch job when you roll into work at midday.

You can also try ordering by disk_reads and executions. Executions is useful because some poor applications send the same SQL statement way too many times. This SQL assumes you use bind variables correctly.

Then, you can take the sql_id and child_number of a statement and feed them into this baby:-

SELECT * FROM table(DBMS_XPLAN.DISPLAY_CURSOR('&sql_id', &child));

This shows the actual plan from the SQL cache and the full text of the SQL.

• After I ran this that the memory is almost exactly the same and that's because the generator hasn't actually done anything yet it's not holding those million values in memory it's waiting for me to grab the next one.

• Basically it didn't take any time because as soon as it gets to the first yield statement it stops.

• I think that it is generator a little bit more readable and it also gives you big performance boosts not only with execution time but with memory.

• As well and you can still use all of the comprehensions and this generator expression here so you don't lose anything in that area. So those are a few reasons why you would use generators and also some of the advantages that come along with that.

When you include the '.' you are essentially giving the "full path" to the executable bash script, so your shell does not need to check your PATH variable. Without the '.' your shell will look in your PATH variable (which you can see by running echo $PATH to see if the command you typed lives in any of the folders on your PATH. If it doesn't (as is the case with manage.py) it says it can't find the file. It is considered bad practice to include the current directory on your PATH, which is explained reasonably well here: http://www.faqs.org/faqs/unix-faq/faq/part2/section-13.html

CMake (Cross platform make) is a build system generator. It doesn't build your source, instead, generates what a build system needs: the build scripts. Doing so you don't need to write or maintain platform specific build files. CMake uses relatively high level CMake language which usually written in CMakeLists.txt files. Your general workflow when consuming third party libraries usually boils down the following commands:

cmake -S thelibrary -B build
cmake --build build
cmake --install build

The first line known as configuration step, this generates the build files on your system. -S(ource) is the library source, and -B(uild) folder. CMake falls back to generate build according to your system. it will be MSBuild on Windows, GNU Makefiles on Linux. You can specify the build using -G(enerator) paramater, like:

cmake -G Ninja -S libSource -B build

end of the this step, generates build scripts, like Makefile, *.sln files etc. on build directory.

The second line invokes the actual build command, it's like invoking make on the build folder.

The third line install the library. If you're on Windows, you can quickly open generated project by, cmake --open build.

Now you can use the installed library on your project with configured by CMake, writing your own CMakeLists.txt file. To do so, you'll need to create a your target and find the package you installed using find_package command, which will export the library target names, and link them against your own target.

directly you can use this code it will open all type of files

Intent sharingIntent = new Intent(Intent.ACTION_VIEW);
    Uri screenshotUri = Uri.fromFile(your_file);
    sharingIntent.setType("image/png");
    sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
    String type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(screenshotUri.toString()));
    sharingIntent.setDataAndType(screenshotUri, type == null ? "text/plain" : type);
    startActivity(Intent.createChooser(sharingIntent, "Share using"));

$('input:radio[name="postage"]').change(function(){
    if($(this).val() === 'Yes'){
       // append stuff
    }
});

This will listen for a change event on the radio buttons. At the time the user clicks Yes, the event will fire and you will be able to append anything you like to the DOM.

• How to replace multiple newlines in a row with one newline using Ruby

I come across a situation where i need to insert the data in the database & simultaneously require the primary id using entity framework. Solution :

long id;
IGenericQueryRepository<myentityclass, Entityname> InfoBase = null;
try
 {
    InfoBase = new GenericQueryRepository<myentityclass, Entityname>();
    InfoBase.Add(generalinfo);
    InfoBase.Context.SaveChanges();
    id = entityclassobj.ID;
    return id;
 }

There is nothing called background opacity. Opacity is applied to the element, its contents and all its child elements. And this behavior cannot be changed just by overriding the opacity in child elements.

Child vs parent opacity has been a long standing issue and the most common fix for it is using rgba(r,g,b,alpha) background colors. But in this case, since it is a background-image, that solution won't work. One solution would be to generate the image as a PNG with the required opacity in the image itself. Another solution would be to take the child div out and make it absolutely positioned.

I wanted a more exact and useful answer to this question. Here's the real answer (adjust accordingly if you want a byte array specifically; obviously the math will be off by a factor of 8 bits : 1 byte):

class BitArray {
  constructor(bits = 0) {
    this.uints = new Uint32Array(~~(bits / 32));
  }

  getBit(bit) {
    return (this.uints[~~(bit / 32)] & (1 << (bit % 32))) != 0 ? 1 : 0;
  }

  assignBit(bit, value) {
    if (value) {
      this.uints[~~(bit / 32)] |= (1 << (bit % 32));
    } else {
      this.uints[~~(bit / 32)] &= ~(1 << (bit % 32));
    }
  }

  get size() {
    return this.uints.length * 32;
  }

  static bitsToUints(bits) {
    return ~~(bits / 32);
  }
}

Usage:

let bits = new BitArray(500);
for (let uint = 0; uint < bits.uints.length; ++uint) {
  bits.uints[uint] = 457345834;
}
for (let bit = 0; bit < 50; ++bit) {
  bits.assignBit(bit, 1);
}
str = '';
for (let bit = bits.size - 1; bit >= 0; --bit) {
  str += bits.getBit(bit);
}
str;

Output:

"00011011010000101000101100101010
 00011011010000101000101100101010

Note: This class is really slow to e.g. assign bits (i.e. ~2s per 10 million assignments) if it's created as a global variable, at least in the Firefox 76.0 Console on Linux... If, on the other hand, it's created as a variable (i.e. let bits = new BitArray(1e7);), then it's blazingly fast (i.e. ~300ms per 10 million assignments)!

For more info, see here:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint32Array

Note that I used Uint32Array because there's no way to directly have a bit/byte array (that you can interact with directly) and because even though there's a BigUint64Array, JS only supports 32 bits:

Bitwise operators treat their operands as a sequence of 32 bits

...

The operands of all bitwise operators are converted to...32-bit integers

If you added it in the control panel while your command prompt was open, that won't affect your current command prompt. You'll need to exit and re-open or simply do:

set "path=%path%;c:\program files\java\jdk1.6.0_16\bin"

By way of checking, execute:

echo %path%

from your command prompt and let us know what it is.

Otherwise, make sure there is a javac in that directory by trying:

"c:\program files\java\jdk1.6.0_16\bin\javac.exe"

from the command prompt. You can also tell which executable (if any) is being used with the command:

for %i in (javac.exe) do @echo %~$PATH:i

This is a neat trick similar to the which and/or whence commands in some UNIX-type operating systems.

This happened to me because I had my server running in another Terminal window. Closing the connection solved the problem.

#include <stdio.h>

typedef struct { char* c; char b; } a;

int main()
{
    printf("sizeof(a) == %d", sizeof(a));
}

I get "sizeof(a) == 8", on a 32-bit machine. The total size of the structure will depend on the packing: In my case, the default packing is 4, so 'c' takes 4 bytes, 'b' takes one byte, leaving 3 padding bytes to bring it to the next multiple of 4: 8. If you want to alter this packing, most compilers have a way to alter it, for example, on MSVC:

#pragma pack(1)
typedef struct { char* c; char b; } a;

gives sizeof(a) == 5. If you do this, be careful to reset the packing before any library headers!

Same issue here, Visual Studio 2015 Pro Update 2 on a brand new machine. The editor was extremely slow, typing like chewing gum.

The reason was ESET NOD32 Antivirus 9. It has a thing called "Host Intruder Prevention System (HIPS)" enabled by default. I don't know how useful it this, but it can be disabled or I just added a rule, to allow devenv.exe.

Now it's fine.

I prefered the library davemorrissey/subsampling-scale-image-view over chrisbanes/PhotoView (answer of star18bit)

• Both are active projects (both have some commits in 2015)
• Both have a Demo on the PlayStore
• subsampling-scale-image-view supports large images (above 1080p) without memory exception due to sub sampling, which PhotoView doesn't support
• subsampling-scale-image-view seems to have larger API and better documentation

See How to convert AAR to JAR, if you like to use subsampling-scale-image-view with Eclipse/ADT

It seems like two different scenarios are being mixed together in this discussion:

Scenario 1

Using my parent repository's pointers to submodules, I want to check out the commit in each submodule that the parent repository is pointing to, possibly after first iterating through all submodules and updating/pulling these from remote.

This is, as pointed out, done with

git submodule foreach git pull origin BRANCH
git submodule update

Scenario 2, which I think is what OP is aiming at

New stuff has happened in one or more submodules, and I want to 1) pull these changes and 2) update the parent repository to point to the HEAD (latest) commit of this/these submodules.

This would be done by

git submodule foreach git pull origin BRANCH
git add module_1_name
git add module_2_name
......
git add module_n_name
git push origin BRANCH

Not very practical, since you would have to hardcode n paths to all n submodules in e.g. a script to update the parent repository's commit pointers.

It would be cool to have an automated iteration through each submodule, updating the parent repository pointer (using git add) to point to the head of the submodule(s).

For this, I made this small Bash script:

git-update-submodules.sh

#!/bin/bash

APP_PATH=$1
shift

if [ -z $APP_PATH ]; then
  echo "Missing 1st argument: should be path to folder of a git repo";
  exit 1;
fi

BRANCH=$1
shift

if [ -z $BRANCH ]; then
  echo "Missing 2nd argument (branch name)";
  exit 1;
fi

echo "Working in: $APP_PATH"
cd $APP_PATH

git checkout $BRANCH && git pull --ff origin $BRANCH

git submodule sync
git submodule init
git submodule update
git submodule foreach "(git checkout $BRANCH && git pull --ff origin $BRANCH && git push origin $BRANCH) || true"

for i in $(git submodule foreach --quiet 'echo $path')
do
  echo "Adding $i to root repo"
  git add "$i"
done

git commit -m "Updated $BRANCH branch of deployment repo to point to latest head of submodules"
git push origin $BRANCH

To run it, execute

git-update-submodules.sh /path/to/base/repo BRANCH_NAME

Elaboration

First of all, I assume that the branch with name $BRANCH (second argument) exists in all repositories. Feel free to make this even more complex.

The first couple of sections is some checking that the arguments are there. Then I pull the parent repository's latest stuff (I prefer to use --ff (fast-forwarding) whenever I'm just doing pulls. I have rebase off, BTW).

git checkout $BRANCH && git pull --ff origin $BRANCH

Then some submodule initializing, might be necessary, if new submodules have been added or are not initialized yet:

git submodule sync
git submodule init
git submodule update

Then I update/pull all submodules:

git submodule foreach "(git checkout $BRANCH && git pull --ff origin $BRANCH && git push origin $BRANCH) || true"

Notice a few things: First of all, I'm chaining some Git commands using && - meaning previous command must execute without error.

After a possible successful pull (if new stuff was found on the remote), I do a push to ensure that a possible merge-commit is not left behind on the client. Again, it only happens if a pull actually brought in new stuff.

Finally, the final || true is ensuring that script continues on errors. To make this work, everything in the iteration must be wrapped in the double-quotes and the Git commands are wrapped in parentheses (operator precedence).

My favourite part:

for i in $(git submodule foreach --quiet 'echo $path')
do
  echo "Adding $i to root repo"
  git add "$i"
done

Iterate all submodules - with --quiet, which removes the 'Entering MODULE_PATH' output. Using 'echo $path' (must be in single-quotes), the path to the submodule gets written to output.

This list of relative submodule paths is captured in an array ($(...)) - finally iterate this and do git add $i to update the parent repository.

Finally, a commit with some message explaining that the parent repository was updated. This commit will be ignored by default, if nothing was done. Push this to origin, and you're done.

I have a script running this in a Jenkins job that chains to a scheduled automated deployment afterwards, and it works like a charm.

I hope this will be of help to someone.

You can use the resulting xaml from the SVG as a drawing brush on a rectangle. Something like this:

<Rectangle>
   <Rectangle.Fill>
      --- insert the converted xaml's geometry here ---
   </Rectangle.Fill>
</Rectangle>

{{ data.0 }} should work.

Let's say you wrote data.obj django tries data.obj and data.obj(). If they don't work it tries data["obj"]. In your case data[0] can be written as {{ data.0 }}. But I recommend you to pull data[0] in the view and send it as separate variable.

Like this:

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

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

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

To get the intersection:

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

Hope this answer helps. Vote for it!

This is how to get the last record from all MongoDB documents from the "foo" collection.(change foo,x,y.. etc.)

db.foo.aggregate([{$sort:{ x : 1, date : 1 } },{$group: { _id: "$x" ,y: {$last:"$y"},yz: {$last:"$yz"},date: { $last : "$date" }}} ],{   allowDiskUse:true  })

you can add or remove from the group

There's also:

getent $HOSTNAME

or possibly:

getent `uname -n`

On Solaris 11 the ifconfig command is considered legacy and is being replaced by ipadm

ipadm show-addr

will show the IP addresses on the system for Solaris 11 and later.

1. If your array is declared as static or is global, all the elements in the array already have default default value 0.
2. Some compilers set array's the default to 0 in debug mode.
3. It is easy to set default to 0 : int array[10] = {0};
4. However, for other values, you have use memset() or loop;

example: int array[10]; memset(array,-1, 10 *sizeof(int));

git log remotename/branchname

Will display the log of a given remote branch in that repository, but only the logs that you have "fetched" from their repository to your personal "copy" of the remote repository.

Remember that your clone of the repository will update its state of any remote branches only by doing git fetch. You can't connect directly to the server to check the log there, what you do is download the state of the server with git fetch and then locally see the log of the remote branches.

Perhaps another useful command could be:

git log HEAD..remote/branch

which will show you the commits that are in the remote branch, but not in your current branch (HEAD).

flson's code did not work for me. For those in the similar situation, here is my slightly different code:

<TextField ref='myTextField'/>

get its value using

this.refs.myTextField.input.value

Basically you should use the java.lang.Package class which use the classloader to give you informations about your classes.

example:

String.class.getPackage().getImplementationVersion();
Package.getPackage(this).getImplementationVersion();
Package.getPackage("java.lang.String").getImplementationVersion();

I think logback is known to use this feature to trace the JAR name/version of each class in its produced stacktraces.

Use the following script tag in your jsp/js file:

<script src="http://code.jquery.com/jquery-migrate-1.2.1.js"></script>

this will work for sure.

The switch is faster.

Just try if/else-ing 30 different values inside a loop, and compare it to the same code using switch to see how much faster the switch is.

Now, the switch has one real problem : The switch must know at compile time the values inside each case. This means that the following code:

// WON'T COMPILE
extern const int MY_VALUE ;

void doSomething(const int p_iValue)
{
    switch(p_iValue)
    {
       case MY_VALUE : /* do something */ ; break ;
       default : /* do something else */ ; break ;
    }
}

won't compile.

Most people will then use defines (Aargh!), and others will declare and define constant variables in the same compilation unit. For example:

// WILL COMPILE
const int MY_VALUE = 25 ;

void doSomething(const int p_iValue)
{
    switch(p_iValue)
    {
       case MY_VALUE : /* do something */ ; break ;
       default : /* do something else */ ; break ;
    }
}

So, in the end, the developper must choose between "speed + clarity" vs. "code coupling".

(Not that a switch can't be written to be confusing as hell... Most the switch I currently see are of this "confusing" category"... But this is another story...)

Edit 2008-09-21:

bk1e added the following comment: "Defining constants as enums in a header file is another way to handle this".

Of course it is.

The point of an extern type was to decouple the value from the source. Defining this value as a macro, as a simple const int declaration, or even as an enum has the side-effect of inlining the value. Thus, should the define, the enum value, or the const int value change, a recompilation would be needed. The extern declaration means the there is no need to recompile in case of value change, but in the other hand, makes it impossible to use switch. The conclusion being Using switch will increase coupling between the switch code and the variables used as cases. When it is Ok, then use switch. When it isn't, then, no surprise.

.

Edit 2013-01-15:

Vlad Lazarenko commented on my answer, giving a link to his in-depth study of the assembly code generated by a switch. Very enlightning: http://lazarenko.me/switch/

I needed something to print things out nicely and separate the bits every n-bit. In other words display the leading zeros and show something like this:

n = 5463
output = 0000 0000 0000 0000 0001 0101 0101 0111

So here's what I wrote:

/**
 * Converts an integer to a 32-bit binary string
 * @param number
 *      The number to convert
 * @param groupSize
 *      The number of bits in a group
 * @return
 *      The 32-bit long bit string
 */
public static String intToString(int number, int groupSize) {
    StringBuilder result = new StringBuilder();

    for(int i = 31; i >= 0 ; i--) {
        int mask = 1 << i;
        result.append((number & mask) != 0 ? "1" : "0");

        if (i % groupSize == 0)
            result.append(" ");
    }
    result.replace(result.length() - 1, result.length(), "");

    return result.toString();
}

Invoke it like this:

public static void main(String[] args) {
    System.out.println(intToString(5463, 4));
}

You need to add a reference to System.Web.Extensions.dll in project for System.Web.Script.Serialization error.

Let me show you a little trick.

As Arkanciscan said, you can use CSS3 transitions. But his solution looks different from the original tag.

What you really need to do is this:

This turned out to be a stupid error. My log4j wasn't configured to capture my error output. I was throwing configuration errors in the background and once I fixed those I was good to go and my request mappings worked fine.

To start only stopped containers:

docker start $(docker ps -a -q -f status=exited)

(On windows it works in Powershell).

I found this most useful:

#include <QTextStream>

QTextStream out(stdout);
foreach(QString x, strings)
    out << x << endl;

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

If you don't use innodb_file_per_table, reclaiming disk space is possible, but quite tedious, and requires a significant amount of downtime.

The How To is pretty in-depth - but I pasted the relevant part below.

Be sure to also retain a copy of your schema in your dump.

Currently, you cannot remove a data file from the system tablespace. To decrease the system tablespace size, use this procedure:

Use mysqldump to dump all your InnoDB tables.

Stop the server.

Remove all the existing tablespace files, including the ibdata and ib_log files. If you want to keep a backup copy of the information, then copy all the ib* files to another location before the removing the files in your MySQL installation.

Remove any .frm files for InnoDB tables.

Configure a new tablespace.

Restart the server.

Import the dump files.

I was having huge issues with Error 1050 and 150.

The problem, for me was that I was trying to add a constraint with ON DELETE SET NULL as one of the conditions.

Changing to ON DELETE NO ACTION allowed me to add the required FK constraints.

Unfortunately the MySql error messages are utterly unhelpful so I had to find this solution iteratively and with the help of the answers to the question above.

To exit hitting :q will let you quit.

If you want to quit without saving you can hit :q!

A google search on "vim cheatsheet" can provide you with a reference you should print out with a collection of quick shortcuts.

http://www.fprintf.net/vimCheatSheet.html

There's a great article on Mozilla's MDN docs that describes exactly this issue:

The "Unicode Problem" Since DOMStrings are 16-bit-encoded strings, in most browsers calling window.btoa on a Unicode string will cause a Character Out Of Range exception if a character exceeds the range of a 8-bit byte (0x00~0xFF). There are two possible methods to solve this problem:

• the first one is to escape the whole string (with UTF-8, see encodeURIComponent) and then encode it;
• the second one is to convert the UTF-16 DOMString to an UTF-8 array of characters and then encode it.

A note on previous solutions: the MDN article originally suggested using unescape and escape to solve the Character Out Of Range exception problem, but they have since been deprecated. Some other answers here have suggested working around this with decodeURIComponent and encodeURIComponent, this has proven to be unreliable and unpredictable. The most recent update to this answer uses modern JavaScript functions to improve speed and modernize code.

If you're trying to save yourself some time, you could also consider using a library:

• js-base64 (NPM, great for Node.js)
• base64-js

Encoding UTF8 ? base64

function b64EncodeUnicode(str) {
    // first we use encodeURIComponent to get percent-encoded UTF-8,
    // then we convert the percent encodings into raw bytes which
    // can be fed into btoa.
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g,
        function toSolidBytes(match, p1) {
            return String.fromCharCode('0x' + p1);
    }));
}

b64EncodeUnicode('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n'); // "Cg=="

Decoding base64 ? UTF8

function b64DecodeUnicode(str) {
    // Going backwards: from bytestream, to percent-encoding, to original string.
    return decodeURIComponent(atob(str).split('').map(function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
    }).join(''));
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"
b64DecodeUnicode('Cg=='); // "\n"

The pre-2018 solution (functional, and though likely better support for older browsers, not up to date)

Here is the the current recommendation, direct from MDN, with some additional TypeScript compatibility via @MA-Maddin:

// Encoding UTF8 ? base64

function b64EncodeUnicode(str) {
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g, function(match, p1) {
        return String.fromCharCode(parseInt(p1, 16))
    }))
}

b64EncodeUnicode('? à la mode') // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n') // "Cg=="

// Decoding base64 ? UTF8

function b64DecodeUnicode(str) {
    return decodeURIComponent(Array.prototype.map.call(atob(str), function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2)
    }).join(''))
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU=') // "? à la mode"
b64DecodeUnicode('Cg==') // "\n"

The original solution (deprecated)

This used escape and unescape (which are now deprecated, though this still works in all modern browsers):

function utf8_to_b64( str ) {
    return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
    return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

And one last thing: I first encountered this problem when calling the GitHub API. To get this to work on (Mobile) Safari properly, I actually had to strip all white space from the base64 source before I could even decode the source. Whether or not this is still relevant in 2017, I don't know:

function b64_to_utf8( str ) {
    str = str.replace(/\s/g, '');    
    return decodeURIComponent(escape(window.atob( str )));
}

You can use rsplit

string.rsplit('delimeter',1)[1]

To get the string from reverse.

There is builtin procedure to check dependents:
For an example ,

Execute sp_depends @objname=N'ssc.RegDash_RoutingAct'

Bottom line is that you'll have to write a new css rule for that.

Depending on which bundle of Twitter Bootstrap you're using, you should have variables for the various colours.

Try something like:

.table tbody tr > td {
  &.success { background-color: $green; }
  &.info { background-color: $blue; }
  ...
}

Surely there's a way to use extend or the LESS equivalent to avoid repeating the same styling.

If you are OK with converting the input button to a server side control by specifying runat="server", and you are using asp.net, an option could be using the HtmlButton.OnServerClick property.

<input id="foo "runat="server" type="button" onserverclick="foo_OnClick" />

This should work and call foo_OnClick in your server side code. Also notice that based on Microsoft documentation linked above, you should also be able to use the HTML 4.0 tag.

If table does not have relation, just copy all in new table with row number and remove old and rename new one with old one.

Select   RowNum = ROW_NUMBER() OVER(ORDER BY(SELECT NULL)) , * INTO cdm.dbo.SALES2018 from 
(
select * from SALE2018) as SalesSource

Yes:

>>> from collections import Counter
>>> x = Counter({'a':5, 'b':3, 'c':7})

Using the sorted keyword key and a lambda function:

>>> sorted(x.items(), key=lambda i: i[1])
[('b', 3), ('a', 5), ('c', 7)]
>>> sorted(x.items(), key=lambda i: i[1], reverse=True)
[('c', 7), ('a', 5), ('b', 3)]

This works for all dictionaries. However Counter has a special function which already gives you the sorted items (from most frequent, to least frequent). It's called most_common():

>>> x.most_common()
[('c', 7), ('a', 5), ('b', 3)]
>>> list(reversed(x.most_common()))  # in order of least to most
[('b', 3), ('a', 5), ('c', 7)]

You can also specify how many items you want to see:

>>> x.most_common(2)  # specify number you want
[('c', 7), ('a', 5)]

$post = Post::select(DB::raw('count(*) as user_count, category_id'))
              ->groupBy('category_id')
              ->get();

This is an example which results count of post by category.

Another way is using set data type.

Some characteristic of Sets: Sets are unordered, can include mixed data types, elements in a set cannot be repeated, are mutable.

Solving your question:

df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
sorted(set(df.A))

The answer in List type:

[1, 2, 3, 6, 8]

had same problem today, Your topic helped me so here goes solution ;)

 alert(result.d[0].EmployeeTitle);

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

In crystal report formulafield date function aavailable there pass your date-time format in that You Will get the Date only here

Example: Date({MyTable.dte_QDate})

So do the following ,

Lets say your branch name is my_branch and this has the extra commits.

1. git checkout -b my_branch_with_extra_commits (Keeping this branch saved under a different name)
2. gitk (Opens git console)
3. Look for the commit you want to keep. Copy the SHA of that commit to a notepad.
4. git checkout my_branch
5. gitk (This will open the git console )
6. Right click on the commit you want to revert to (State before your changes) and click on "reset branch to here"
7. Do a git pull --rebase origin branch_name_to _merge_to
8. git cherry-pick <SHA you copied in step 3. >

Now look at the local branch commit history and make sure everything looks good.

an abstract class can have member variables that needs to be initialized,so they can be initialized in the abstract class constructor and this constructor is called when derived class object is initialized.

to be secured, you should execute 3 commands :

cmdkey /generic:"server-address" /user:"username" /pass:"password"
mstsc /v:server-address
cmdkey /delete:server-address

first command to save the credential

second command to open remote desktop

and the third command to delete the credential

all of these commands can be saved in a batch file(bat).

Not sure if I understand your question correctly, but provided that you can call the Python executable from the console and just want to capture its output in Java, you can use the exec() method in the Java Runtime class.

Process p = Runtime.getRuntime().exec("python yourapp.py");

You can read up on how to actually read the output here:

http://www.devdaily.com/java/edu/pj/pj010016

There is also an Apache library (the Apache exec project) that can help you with this. You can read more about it here:

http://www.devdaily.com/java/java-exec-processbuilder-process-1

http://commons.apache.org/exec/

As long as your script is executable and doesn't have any extension you can drag it as-is to the right side (Document side) of the Dock and it will run in a terminal window when clicked instead of opening an editor.

If you want to have an extension (like foo.sh), you can go to the file info window in Finder and change the default application for that particular script from whatever it is (TextEdit, TextMate, whatever default is set on your computer for .sh files) to Terminal. It will then just execute instead of opening in a text editor. Again, you will have to drag it to the right side of the Dock.

They work almost the same as today. However, be sure you include [] around your IP.

For example : http://[1fff:0:a88:85a3::ac1f]:8001/index.html

Wikipedia has a pretty good article about IPv6: http://en.wikipedia.org/wiki/IPv6#Addressing

As @Didier said, you can change your delimiter to something other than /:

grep -rl $oldstring /path/to/folder | xargs sed -i s@$oldstring@$newstring@g

you can solve it

sudo nano /etc/apache2/ports.conf

and changed Listen to 8080

I've devised the below demo using a mix of tricks which allows simulating if/else scenarios for some properties. Any property which is numerical in its essence is easy target for this method, but properties with text values are.

This code has 3 if/else scenarios, for opacity, background color & width. All 3 are governed by two Boolean variables bool and its opposite notBool.

Those two Booleans are the key to this method, and to achieve a Boolean out of a none-boolean dynamic value, requires some math which luckily CSS allows using min & max functions.

Obviously those functions (min/max) are supported in recent browsers' versions which also supports CSS custom properties (variables).

var elm = document.querySelector('div')

setInterval(()=>{
  elm.style.setProperty('--width', Math.round(Math.random()*80 + 20))
}, 1000)

:root{
   --color1: lightgreen;
   --color2: salmon;
   --width: 70;  /* starting value, randomly changed by javascript every 1 second */
}

div{
 --widthThreshold: 50;
 --is-width-above-limit: Min(1, Max(var(--width) - var(--widthThreshold), 0));
 --is-width-below-limit: calc(1 - var(--is-width-above-limit));
 
 --opacity-wide: .4;     /* if width is ABOVE 50 */
 --radius-narrow: 10px;  /* if width is BELOW 50 */
 --radius-wide: 60px;    /* if width is ABOVE 50 */
 --height-narrow: 80px;  /* if width is ABOVE 50 */
 --height-wide: 160px;   /* if width is ABOVE 50 */
 
 --radiusToggle: Max(var(--radius-narrow), var(--radius-wide) * var(--is-width-above-limit));
 --opacityToggle: calc(calc(1 + var(--opacity-wide)) - var(--is-width-above-limit));
 --colorsToggle: var(--color1) calc(100% * var(--is-width-above-limit)), 
                 var(--color2) calc(100% * var(--is-width-above-limit)), 
                 var(--color2) calc(100% * (1 - var(--is-width-above-limit)));
  
 --height: Max(var(--height-wide) * var(--is-width-above-limit), var(--height-narrow));
 
 height: var(--height);
 text-align: center;
 line-height: var(--height);

 width: calc(var(--width) * 1%);
 opacity: var(--opacityToggle);
 border-radius: var(--radiusToggle);
 background: linear-gradient(var(--colorsToggle));

 transition: .3s;
}

/* prints some variables */
div::before{
  counter-reset: aa var(--width);
  content: counter(aa)"%";
}

div::after{
  counter-reset: bb var(--is-width-above-limit);
  content: " is over 50% ? "counter(bb);
}

<div></div>

Another simply way using clamp:

label{ --width: 150 }
input:checked + div{ --width: 400 }

div{
  --isWide: Clamp(0,   (var(--width) - 150) * 99999  , 1);
  width: calc(var(--width) * 1px);
  height: 150px;
  border-radius: calc(var(--isWide) * 20px); /* if wide - add radius */
  background: lightgreen;
}

<label>
<input type='checkbox' hidden> 
<div>Click to toggle width</div>
</label>

Best so far:

I have come up with a totally unique method, which is even simpler!

This method is so cool because it is so easy to implement and also to understand. it is based on animation step() function.

Since bool can be easily calculated as either 0 or 1, this value can be used in the step! if only a single step is defined, then the if/else problem is solved.

Using the keyword forwards persist the changes.

var elm = document.querySelector('div')

setInterval(()=>{
  elm.style.setProperty('--width', Math.round(Math.random()*80 + 20))
}, 1000)

:root{
   --color1: salmon;
   --color2: lightgreen;
}

@keyframes if-over-threshold--container{
  to{ 
     --height: 160px;
     --radius: 30px;
     --color: var(--color2);
     opacity: .4; /* consider this as additional, never-before, style */
  }
}

@keyframes if-over-threshold--after{
  to{ 
    content: "true"; 
    color: green; 
  }
}

div{
 --width: 70;           /* must be unitless */
 --height: 80px;
 --radius: 10px;
 --color: var(--color1);
 --widthThreshold: 50;
 --is-width-over-threshold: Min(1, Max(var(--width) - var(--widthThreshold), 0));

 
 text-align: center;
 white-space: nowrap;
 transition: .3s;
 
 /* if element is narrower than --widthThreshold */
 width: calc(var(--width) * 1%);
 height: var(--height);
 line-height: var(--height);
 border-radius: var(--radius);
 background: var(--color);

 /* else */
 animation: if-over-threshold--container forwards steps(var(--is-width-over-threshold));
}

/* prints some variables */
div::before{
  counter-reset: aa var(--width);
  content: counter(aa)"% is over 50% width ? ";
}

div::after{
  content: 'false'; 
  font-weight: bold; 
  color: darkred;
  
  /* if element is wider than --widthThreshold */
  animation: if-over-threshold--after forwards steps(var(--is-width-over-threshold)) ;
}

<div></div>

I've found a Chrome bug which I have reported that can affect this method in some situations where specific type of calculations is necessary, but there's a way around it.

https://bugs.chromium.org/p/chromium/issues/detail?id=1138497

import { Component, HostListener } from '@angular/core';

@Component({
    selector: 'custom-dropdown',
    template: `
        <div class="custom-dropdown-container">
            Dropdown code here
        </div>
    `
})
export class CustomDropdownComponent {
    thisElementClicked: boolean = false;

    constructor() { }

    @HostListener('click', ['$event'])
    onLocalClick(event: Event) {
        this.thisElementClicked = true;
    }

    @HostListener('document:click', ['$event'])
    onClick(event: Event) {
        if (!this.thisElementClicked) {
            //click was outside the element, do stuff
        }
        this.thisElementClicked = false;
    }
}

DOWNSIDES: - Two click event listeners for every one of these components on page. Don't use this on components that are on the page hundreds of times.

Unless ADB is running as root (as it would on an emulator) you cannot generally view anything under /data unless an application which owns it has made it world readable. Further, you cannot browse the directory structure - you can only list files once you get to a directory where you have access, by explicitly entering its path.

Broadly speaking you have five options:

• Do the investigation within the owning app

• Mark the files in question as public, and use something (adb shell or adb pull) where you can enter a full path name, instead of trying to browse the tree

• Have the owning app copy the entire directory to the SD card

• Use an emulator or rooted device where adb (and thus the ddms browser's access) can run as root (or use a root file explorer or a rooted device)

• use adb and the run-as tool with a debuggable apk to get a command line shell running as the app's user id. For those familiar with the unix command line, this can be the most effective (though the toolbox sh on android is limited, and uses its tiny vocabulary of error messages in misleading ways)

Running this little piece of code allowed me to understand the order function

  order=order(x), 
  sort=sort(x)
)

I know its quite late but for anyone looking to do it from now on, I hope this answer proves of some help. If you have CodeRush Express (free version, and a 'must have') installed, it offers a simple way to change a project wide namespace. You just place your cursor on the namespace that you want to change and it shall display a smart tag (a little blue box) underneath namespace string. You can either click that box or press Ctrl + keys to see the Rename option. Select it and then type in the new name for the project wide namespace, click Apply and select what places in your project you'd want it to change, in the new dialog and OK it. Done! :-)

Look at the keys and indentation in your print_r:

echo $myarray[0]['email'];

echo $myarray[0]['gender'];

...etc

Apart from the aformentioned two methods (edit /etc/apache2/apache2.conf or add Options -Indexes in .htaccess file), here is another one

a2dismod autoindex

Restart the apache2 server afterwards

sudo service apache2 restart

Actually, you can process the find command output in a copy command in two ways:

1. If the find command's output doesn't contain any space, i.e if the filename doesn't contain a space in it, then you can use:

   Syntax:
       find <Path> <Conditions> | xargs cp -t <copy file path>
   Example:
       find -mtime -1 -type f | xargs cp -t inner/
   

2. But our production data files might contain spaces, so most of time this command is effective:

   Syntax:
      find <path> <condition> -exec cp '{}' <copy path> \;
   
   Example 
      find -mtime -1 -type f -exec cp '{}' inner/ \;
   

In the second example, the last part, the semi-colon is also considered as part of the find command, and should be escaped before pressing Enter. Otherwise you will get an error something like:

find: missing argument to `-exec'

1. You need to add the L character to the end of the number to make Java recognize it as a long.

   long i = 12345678910L;
   

2. Yes.

See Primitive Data Types which says "An integer literal is of type long if it ends with the letter L or l; otherwise it is of type int."

Check out copyOfRange; and example:

int[] arr2 = Arrays.copyOfRange(arr,0,3);

In my experience, it has expired at the end of that month. That is based on the fact that I can use it during that month, and that month is when my bank sends a new one.

Try:

select
     id,
     StartDate,
CASE WHEN StartDate IS NULL
    THEN 'Awaiting'
    ELSE 'Approved' END AS StartDateStatus
FROM myTable

You code would have been doing a When StartDate = NULL, I think.

NULL is never equal to NULL (as NULL is the absence of a value). NULL is also never not equal to NULL. The syntax noted above is ANSI SQL standard and the converse would be StartDate IS NOT NULL.

You can run the following:

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

And this returns:

EqualityCheck = 0
InEqualityCheck = 0
NullComparison = 1

For completeness, in SQL Server you can:

SET ANSI_NULLS OFF;

Which would result in your equals comparisons working differently:

SET ANSI_NULLS OFF

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

Which returns:

EqualityCheck = 1
InEqualityCheck = 0
NullComparison = 1

But I would highly recommend against doing this. People subsequently maintaining your code might be compelled to hunt you down and hurt you...

Also, it will no longer work in upcoming versions of SQL server:

Definition of declarator

The term declarator will come up a lot, so let's understand it.

From the language grammar, we find that the following underline characters are declarators:

int f(int x, int y);
    ^^^^^^^^^^^^^^^

int f(int x, int y) { return x + y; }
    ^^^^^^^^^^^^^^^

int f();
    ^^^

int f(x, y) int x; int y; { return x + y; }
    ^^^^^^^

Declarators are part of both function declarations and definitions.

There are 2 types of declarators:

• parameter type list
• identifier list

Parameter type list

Declarations look like:

int f(int x, int y);

Definitions look like:

int f(int x, int y) { return x + y; }

It is called parameter type list because we must give the type of each parameter.

Identifier list

Definitions look like:

int f(x, y)
    int x;
    int y;
{ return x + y; }

Declarations look like:

int g();

We cannot declare a function with a non-empty identifier list:

int g(x, y);

because 6.7.5.3 "Function declarators (including prototypes)" says:

3 An identifier list in a function declarator that is not part of a definition of that function shall be empty.

It is called identifier list because we only give the identifiers x and y on f(x, y), types come after.

This is an older method, and shouldn't be used anymore. 6.11.6 Function declarators says:

1 The use of function declarators with empty parentheses (not prototype-format parameter type declarators) is an obsolescent feature.

and the Introduction explains what is an obsolescent feature:

Certain features are obsolescent, which means that they may be considered for withdrawal in future revisions of this International Standard. They are retained because of their widespread use, but their use in new implementations (for implementation features) or new programs (for language [6.11] or library features [7.26]) is discouraged

f() vs f(void) for declarations

When you write just:

void f();

it is necessarily an identifier list declaration, because 6.7.5 "Declarators" says defines the grammar as:

direct-declarator:
    [...]
    direct-declarator ( parameter-type-list )
    direct-declarator ( identifier-list_opt )

so only the identifier-list version can be empty because it is optional (_opt).

direct-declarator is the only grammar node that defines the parenthesis (...) part of the declarator.

So how do we disambiguate and use the better parameter type list without parameters? 6.7.5.3 Function declarators (including prototypes) says:

10 The special case of an unnamed parameter of type void as the only item in the list specifies that the function has no parameters.

So:

void f(void);

is the way.

This is a magic syntax explicitly allowed, since we cannot use a void type argument in any other way:

void f(void v);
void f(int i, void);
void f(void, int);

What can happen if I use an f() declaration?

Maybe the code will compile just fine: 6.7.5.3 Function declarators (including prototypes):

14 The empty list in a function declarator that is not part of a definition of that function specifies that no information about the number or types of the parameters is supplied.

So you can get away with:

void f();
void f(int x) {}

Other times, UB can creep up (and if you are lucky the compiler will tell you), and you will have a hard time figuring out why:

void f();
void f(float x) {}

See: Why does an empty declaration work for definitions with int arguments but not for float arguments?

f() and f(void) for definitions

f() {}

vs

f(void) {}

are similar, but not identical.

6.7.5.3 Function declarators (including prototypes) says:

14 An empty list in a function declarator that is part of a definition of that function specifies that the function has no parameters.

which looks similar to the description of f(void).

But still... it seems that:

int f() { return 0; }
int main(void) { f(1); }

is conforming undefined behavior, while:

int f(void) { return 0; }
int main(void) { f(1); }

is non conforming as discussed at: Why does gcc allow arguments to be passed to a function defined to be with no arguments?

TODO understand exactly why. Has to do with being a prototype or not. Define prototype.

I had a tab character instead of spaces. Replacing the tab '\t' fixed the problem.

Cut and paste the whole doc into an editor like Notepad++ and display all characters.

In python, A dynamic array is an 'array' from the array module. E.g.

from array import array
x = array('d')          #'d' denotes an array of type double
x.append(1.1)
x.append(2.2)
x.pop()                 # returns 2.2

This datatype is essentially a cross between the built-in 'list' type and the numpy 'ndarray' type. Like an ndarray, elements in arrays are C types, specified at initialization. They are not pointers to python objects; this may help avoid some misuse and semantic errors, and modestly improves performance.

However, this datatype has essentially the same methods as a python list, barring a few string & file conversion methods. It lacks all the extra numerical functionality of an ndarray.

See https://docs.python.org/2/library/array.html for details.

IMO, the justification for a long param list is that the data or context is dynamic in nature, think of printf(); a good example of using varargs. A better way to handle such cases is by passing a stream or xml structure, this again minimises the number of parameters.

A machine surely wouldn't mind a large number of arguments, but developers do, also think of the maintenance overhead, the number of unit test cases and validation checks. Designers also hate lengthy args list, more arguments mean more changes to interface definitions, whenever a change is to be done. The questions about the coupling/cohesion spring from above aspects.

I use this one:

from pyspark.sql.functions import col
df.select(['vin',col('timeStamp').alias('Date')]).show()

I wanted send some strings to backend server. I didnt use json with multipart, I have used request params.

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public void uploadFile(HttpServletRequest request,
        HttpServletResponse response, @RequestParam("uuid") String uuid,
        @RequestParam("type") DocType type,
        @RequestParam("file") MultipartFile uploadfile)

Url would look like

http://localhost:8080/file/upload?uuid=46f073d0&type=PASSPORT

I am passing two params (uuid and type) along with file upload. Hope this will help who don't have the complex json data to send.

You could to this trick: create a file 1 hour ago, and use the -newer file argument.

(Or use touch -t to create such a file).

Presumably, since you're not providing a value for the DB_ID column, that value is being populated by a row-level before insert trigger defined on the table. That trigger, presumably, is selecting the value from a sequence.

Since the data was moved (presumably recently) from the production database, my wager would be that when the data was copied, the sequence was not modified as well. I would guess that the sequence is generating values that are much lower than the largest DB_ID that is currently in the table leading to the error.

You could confirm this suspicion by looking at the trigger to determine which sequence is being used and doing a

SELECT <<sequence name>>.nextval
  FROM dual

and comparing that to

SELECT MAX(db_id)
  FROM cmdb_db

If, as I suspect, the sequence is generating values that already exist in the database, you could increment the sequence until it was generating unused values or you could alter it to set the INCREMENT to something very large, get the nextval once, and set the INCREMENT back to 1.

this will clear Task(stack of activities) and begin new Task

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
System.exit(1);

I have added app.UseStaticFiles(); this code in my startup.cs than it is fixed

Instead of beginUpdates()/endUpdates(), the recommended call is now:

tableView.performBatchUpdates(nil, completion: nil)

Apple says, regarding beginUpdates/endUpdates: "Use the performBatchUpdates(_:completion:) method instead of this one whenever possible."

See: https://developer.apple.com/documentation/uikit/uitableview/1614908-beginupdates

Note also, each command's exit status is stored in the shell variable $?, which you can check immediately after running the command. A non-zero status indicates failure:

my_command
if [ $? -eq 0 ]
then
    echo "it worked"
else
    echo "it failed"
fi

stop-service -inputobject $(get-service -ComputerName remotePC -Name Spooler)

This fails because of your variables -ComputerName remotePC needs to be a variable $remotePC or a string "remotePC" -Name Spooler(same thing for spooler)

Change the project interpreter to ~/anaconda2/python/bin by going to File -> Settings -> Project -> Project Interpreter. Also update the run configuration to use the project default Python interpreter via Run -> Edit Configurations. This makes PyCharm use Anaconda instead of the default Python interpreter under usr/bin/python27.

            SqlConnection conn = new SqlConnection("Data source=USER-PC; Database=Emp123;User Id=sa;Password=sa123");
            conn.Open();
                SqlCommand cmd = new SqlCommand("insert into <Table Name>values(1,'nagendra',10000);",conn);

            }
            Console.ReadKey();

    }
    }
}

You may try this

 EditText et = (EditText) findViewById(R.id.myeditText);
    et.setFilters(new InputFilter[]{ new InputFilter.LengthFilter(140) }); // maximum length is 140

A third solution I hardly ever see mentioned is MySQL specific and looks like this:

SELECT id, MAX(rev) AS rev
 , 0+SUBSTRING_INDEX(GROUP_CONCAT(numeric_content ORDER BY rev DESC), ',', 1) AS numeric_content
FROM t1
GROUP BY id

Yes it looks awful (converting to string and back etc.) but in my experience it's usually faster than the other solutions. Maybe that just for my use cases, but I have used it on tables with millions of records and many unique ids. Maybe it's because MySQL is pretty bad at optimizing the other solutions (at least in the 5.0 days when I came up with this solution).

One important thing is that GROUP_CONCAT has a maximum length for the string it can build up. You probably want to raise this limit by setting the group_concat_max_len variable. And keep in mind that this will be a limit on scaling if you have a large number of rows.

Anyway, the above doesn't directly work if your content field is already text. In that case you probably want to use a different separator, like \0 maybe. You'll also run into the group_concat_max_len limit quicker.

You can use .delay() before an animation, like this:

$("#myElem").show().delay(5000).fadeOut();

If it's not an animation, use setTimeout() directly, like this:

$("#myElem").show();
setTimeout(function() { $("#myElem").hide(); }, 5000);

You do the second because .hide() wouldn't normally be on the animation (fx) queue without a duration, it's just an instant effect.

Or, another option is to use .delay() and .queue() yourself, like this:

$("#myElem").show().delay(5000).queue(function(n) {
  $(this).hide(); n();
});

Use a table variable if for a very small quantity of data (thousands of bytes)

Use a temporary table for a lot of data

Another way to think about it: if you think you might benefit from an index, automated statistics, or any SQL optimizer goodness, then your data set is probably too large for a table variable.

In my example, I just wanted to put about 20 rows into a format and modify them as a group, before using them to UPDATE / INSERT a permanent table. So a table variable is perfect.

But I am also running SQL to back-fill thousands of rows at a time, and I can definitely say that the temporary tables perform much better than table variables.

This is not unlike how CTE's are a concern for a similar size reason - if the data in the CTE is very small, I find a CTE performs as good as or better than what the optimizer comes up with, but if it is quite large then it hurts you bad.

My understanding is mostly based on http://www.developerfusion.com/article/84397/table-variables-v-temporary-tables-in-sql-server/, which has a lot more detail.

This usually happens when you have edited a file from Windows and now trying to execute that from some unix based machine.

The solution presented on Linux Forum worked for me (many times):

perl -i -pe's/\r$//;' <file name here>

Hope this helps.

PS: you need to have perl installed on your unix/linux machine.

Are you just looking to verify that the file is of a given extension? You can simplify what you are trying to do with something like this:

(.*?)\.(jpg|gif|doc|pdf)$

Then, when you call IsMatch() make sure to pass RegexOptions.IgnoreCase as your second parameter. There is no reason to have to list out the variations for casing.

Edit: As Dario mentions, this is not going to work for the RegularExpressionValidator, as it does not support casing options.

Use:

byte[] data = Base64.encode(base64str);

Encoding converts to Base64

You would need to reference commons codec from your project in order for that code to work.

For java8:

import java.util.Base64

If you have both versions of PHP installed, you can switch between versions using the link and unlink brew commands.

For example, to switch between PHP 7.4 and PHP 7.3

brew unlink [email protected]
brew link [email protected]

PS: both versions of PHP have be installed for these commands to work.

The following will Return All Procedures in selected database

Simply do:

This is what worked for me. Very simple jQuery and CSS to make responsive carousel works independently of carousels on the same page. Highly customizable but basically a div with white-space nowrap containing a bunch of inline-block elements and put the last one at the beginning to move back or the first one to the end to move forward.

The title attribute is meant to give more information. It's not useful for SEO so it's never a good idea to have the same text in the title and alt which is meant to describe the image or input is vs. what it does. for instance:

<button title="prints out hello world">Sample Buttons</button>

<img title="Hms beagle in the straits of magellan" alt="HMS Beagle painting" src="hms-beagle.jpg" />

The title attribute will make a tool tip, but it will be controlled by the browser as far as where it shows up and what it looks like. If you want more control there are third party jQuery options, many css templates such as Bootstrap have built in solutions, and you can also write a simple css solution if you want. check out this w3schools solution.

First of all, why is the map a HashMap<String, ArrayList<String>> and not a HashMap<String, List<String>>? Is there some reason why the value must be a specific implementation of interface List (ArrayList in this case)?

Arrays.asList does not return a java.util.ArrayList, so you can't assign the return value of Arrays.asList to a variable of type ArrayList.

Instead of:

allWords = Arrays.asList(strTemp.toLowerCase().split("\\s+"));

Try this:

allWords.addAll(Arrays.asList(strTemp.toLowerCase().split("\\s+")));

Removing the inputs with jQuery works for me:

$(".select2-search, .select2-focusser").remove();
