You can use BindingAdapter like this:

@BindingAdapter("bringToFront")
public static void bringToFront(View view, Boolean flag) {
    if (flag) {
        view.bringToFront();
    }
}


  <ImageView
        ...
        app:bringToFront="@{true}"/>

Use logcat tool with -d or -f switch and exec() method.

Saving to a file on the host computer:

exec( "adb logcat -d > logcat.log" ) // logcat is written to logcat.log file on the host.

If you are just saving to a file on the device itself, you can use:

exec( "adb logcat -f logcat.log" ) // logcat is written to logcat.log file on the device.

You can use the attribute df.empty to check whether it's empty or not:

if df.empty:
    print('DataFrame is empty!')

Gnu GCC has a builtin function for comparing types __builtin_types_compatible_p.

https://gcc.gnu.org/onlinedocs/gcc-3.4.5/gcc/Other-Builtins.html

This built-in function returns 1 if the unqualified versions of the types type1 and type2 (which are types, not expressions) are compatible, 0 otherwise. The result of this built-in function can be used in integer constant expressions.

This built-in function ignores top level qualifiers (e.g., const, volatile). For example, int is equivalent to const int.

Used in your example:

double doubleVar;
if(__builtin_types_compatible_p(typeof(doubleVar), double)) {
    printf("doubleVar is of type double!");
}

A property can be declared in two ways.

• Creating the getter, setter methods for an attribute and then passing these as argument to property function
• Using the @property decorator.

You can have a look at few examples I have written about properties in python.

One tiny addition to JB Jansen's answer - in the main readdir() loop I'd add this:

  if (dir->d_type == DT_REG)
  {
     printf("%s\n", dir->d_name);
  }

Just checking if it's really file, not (sym)link, directory, or whatever.

NOTE: more about struct dirent in libc documentation.

Here's something else to keep in mind: For now (PHP 5.2) the PDO library is buggy. It's full of strange bugs. For example: before storing a PDOStatement in a variable, the variable should be unset() to avoid a ton of bugs. Most of these have been fixed in PHP 5.3 and they will be released in early 2009 in PHP 5.3 which will probably have many other bugs. You should focus on using PDO for PHP 6.1 if you want a stable release and using PDO for PHP 5.3 if you want to help the community.

Your script is executing , you just can't use document.write from it. Use an alert to test it and avoid using document.write. The statements of your js file with document.write will not be executed and the rest of the function will be executed.

In Python you can use (.)\1{9,}

• (.) makes group from one char (any char)
• \1{9,} matches nine or more characters from 1st group

example:

txt = """1. aaaaaaaaaaaaaaa
2. bb
3. cccccccccccccccccccc
4. dd
5. eeeeeeeeeeee"""
rx = re.compile(r'(.)\1{9,}')
lines = txt.split('\n')
for line in lines:
    rxx = rx.search(line)
    if rxx:
        print line

Output:

1. aaaaaaaaaaaaaaa
3. cccccccccccccccccccc
5. eeeeeeeeeeee

You can pass an enum through as a string.

public enum CountType {
    ONE,
    TWO,
    THREE
}

private CountType count;
count = ONE;

String countString = count.name();

CountType countToo = CountType.valueOf(countString);

Given strings are supported you should be able to pass the value of the enum around with no problem.

typeperf gives me issues when it randomly doesn't work on some computers (Error: No valid counters.) or if the account has insufficient rights. Otherwise, here is a way to extract just the value from its output. It still needs rounding though:

@for /f "delims=, tokens=2" %p in ('typeperf "\Processor(_Total)\% Processor Time" -sc 3 ^| find ":"') do @echo %~p%

Powershell has two cmdlets to get the percent utilization for all CPUs: Get-Counter (preferred) or Get-WmiObject:

Powershell "Get-Counter '\Processor(*)\% Processor Time' | Select -Expand Countersamples | Select InstanceName, CookedValue"

Or,

Powershell "Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime"

To get the overall CPU load with formatted output exactly like the question:

Powershell "[string][int](Get-Counter '\Processor(*)\% Processor Time').Countersamples[0].CookedValue + '%'"

Or,

 Powershell "gwmi Win32_PerfFormattedData_PerfOS_Processor | Select -First 1 | %{'{0}%' -f $_.PercentProcessorTime}"

You can just use return to end the method's execution

For the few who may have (due to SEO complications) ended here trying to calculate the angle between two lines in python, as in (x0, y0), (x1, y1) geometrical lines, there is the below minimal solution (uses the shapely module, but can be easily modified not to):

from shapely.geometry import LineString
import numpy as np

ninety_degrees_rad = 90.0 * np.pi / 180.0

def angle_between(line1, line2):
    coords_1 = line1.coords
    coords_2 = line2.coords

    line1_vertical = (coords_1[1][0] - coords_1[0][0]) == 0.0
    line2_vertical = (coords_2[1][0] - coords_2[0][0]) == 0.0

    # Vertical lines have undefined slope, but we know their angle in rads is = 90° * p/180
    if line1_vertical and line2_vertical:
        # Perpendicular vertical lines
        return 0.0
    if line1_vertical or line2_vertical:
        # 90° - angle of non-vertical line
        non_vertical_line = line2 if line1_vertical else line1
        return abs((90.0 * np.pi / 180.0) - np.arctan(slope(non_vertical_line)))

    m1 = slope(line1)
    m2 = slope(line2)

    return np.arctan((m1 - m2)/(1 + m1*m2))

def slope(line):
    # Assignments made purely for readability. One could opt to just one-line return them
    x0 = line.coords[0][0]
    y0 = line.coords[0][1]
    x1 = line.coords[1][0]
    y1 = line.coords[1][1]
    return (y1 - y0) / (x1 - x0)

And the use would be

>>> line1 = LineString([(0, 0), (0, 1)]) # vertical
>>> line2 = LineString([(0, 0), (1, 0)]) # horizontal
>>> angle_between(line1, line2)
1.5707963267948966
>>> np.degrees(angle_between(line1, line2))
90.0

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

$(window).bind("load", function() {

   // code here 
});

ruby on rails notes has a very nice blogpost about commenting in erb-files

the short version is

to comment a single line use

<%# commented line %>

to comment a whole block use a if false to surrond your code like this

<% if false %>

TL;DR: All well written web sites (/apps) must emit the header X-XSS-Protection: 0 and just forget about this feature. If you want to have extra security that better user agents can provide, use a strict Content-Security-Policy header.

Long answer:

HTTP header X-XSS-Protection is one of those things that Microsoft introduced in Internet Explorer 8.0 (MSIE 8) that was supposed to improve security of incorrectly written web sites.

The idea is to apply some kind of heuristics to try to detect reflection XSS attack and automatically neuter the attack.

The problematic part of this is "heuristics" and "neutering". The heuristics causes false positives and neutering cannot be safely done because it causes side-effects that can be used to implement XSS attacks and DoS attacks on perfectly safe web sites.

The bad part is that if a web site does not emit the header X-XSS-Protection then the browser will behave as if the header X-XSS-Protection: 1 had been emitted. The worst part is that this value is the least-safe value of all possible values for this header!

For a given secure web site (that is, the site does not have reflected XSS vulnerabilities) this "XSS protection" feature allows following attacks:

X-XSS-Protection: 1 allows attacker to selectively block parts of JavaScript and keep rest of the scripts running. This is possible because the heuristics of this feature are simply "if value of any GET parameter is found in the scripting part of the page source, the script will be automatically modified in user agent dependant way". In practice, the attacker can e.g. add parameter disablexss=<script src="framebuster.js" and the browser will automatically remove the string <script src="framebuster.js" from the actual page source. Note that the rest of the page continues run and the attacker just removed this part of page security. In practice, any JS in the page source can be modified. For some cases, a page without XSS vulnerability having reflected content can be used to run selected JavaScript on page due the neutering incorrectly turning plain text data into executable JavaScript code. (That is, turn textual data within a normal DOM text node into content of <script> tag and execute it!)

X-XSS-Protection: 1; mode=block allows attacker to leak data from the page source by using the behavior of the page as side-channel. For example, if the page contains JavaScript code along the lines of var csrf_secret="521231347843", the attacker simply adds an extra parameter e.g. leak=var%20csrf_secret="3 and if the page is NOT blocked, the 3 was incorrect first digit. The attacker tries again, this time leak=var%20csrf_secret="5 and the page loading will be aborted. This allows the attacker to know that the first digit of the secret is 5. The attacker then continues to guess the next digit. This allows easily brute-forcing of CSRF secrets or any other secret value in the <script> source.

In the end, if your site is full of XSS reflection attacks, using the default value of 1 will reduce the attack surface a little bit. However, if your site is secure and you don't emit X-XSS-Protection: 0, your site will be vulnerable with any browser that supports this feature. If you want defense in depth support from browsers against yet-unknown XSS vulnerabilities on your site, use a strict Content-Security-Policy header and keep sending 0 for this mis-feature. That doesn't open your site to any known vulnerabilities.

Currently this feature is enabled by default in MSIE, Safari and Google Chrome. This used to be enabled in Edge but Microsoft already removed this mis-feature from Edge. Mozilla Firefox never implemented this.

This does the same, enhanced with CONTAINS:

Function SingleCellExtract(LookupValue As String, LookupRange As Range, ColumnNumber As Integer, Char As String)
Dim I As Long
Dim xRet As String
For I = 1 To LookupRange.Columns(1).Cells.Count
     If InStr(1, LookupRange.Cells(I, 1), LookupValue) > 0 Then
        If xRet = "" Then
            xRet = LookupRange.Cells(I, ColumnNumber) & Char
        Else
            xRet = xRet & "" & LookupRange.Cells(I, ColumnNumber) & Char
        End If
    End If
Next
SingleCellExtract = Left(xRet, Len(xRet) - 1)
End Function

You don't need to declare the variable. Ajax success function automatically takes up to 3 parameters: Function( Object data, String textStatus, jqXHR jqXHR )

requirement for tkinter:

python 3.6+

and go to shell write the test code like :

I managed to fix this issue without having to add any triple-slash reference to the TS bootstrap file, change to ES6 (which brings a bunch of issues, just as @DatBoi said) update VS2015's NodeJS and/or NPM bundled builds or install typings globally.

Here's what I did in few steps:

• added typings in the project's package.json file.
• added a script block in the package.json file to execute/update typings after each NPM action.
• added a typings.json file in the project's root folder containing a reference to core-js, which is one of the best shim/polyfill packages out there at the moment to fix ES5/ES6 issues.

Here's how the package.json file should look like (relevant lines only):

{
  "version": "1.0.0",
  "name": "YourProject",
  "private": true,
  "dependencies": {
    ...
    "typings": "^1.3.2",
    ...
  },
  "devDependencies": {
    ...
  },
  "scripts": {
      "postinstall": "typings install"
  }
}

And here's the typings.json file:

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160602141332",
    "jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
    "node": "registry:dt/node#6.0.0+20160621231320"
  }
}

(Jasmine and Node are not required, but I suggest to keep them in case you'll need to in the future).

This fix is working fine with Angular2 RC1 to RC4, which is what I needed, but I think it will also fix similar issues with other ES6-enabled library packages as well.

AFAIK, I think this is the cleanest possible way of fixing it without messing up the VS2015 default settings.

For more info and a detailed analysis of the issue, I also suggest to read this post on my blog.

I have used sequelize.js, node.js and transaction in below code and added proper error handling if it doesn't find data it will throw error that no data found with that id

editLocale: async (req, res) => {

    sequelize.sequelize.transaction(async (t1) => {

        if (!req.body.id) {
            logger.warn(error.MANDATORY_FIELDS);
            return res.status(500).send(error.MANDATORY_FIELDS);
        }

        let id = req.body.id;

        let checkLocale= await sequelize.Locale.findOne({
            where: {
                id : req.body.id
            }
        });

        checkLocale = checkLocale.get();
        if (checkLocale ) {
            let Locale= await sequelize.Locale.update(req.body, {
                where: {
                    id: id
                }
            });

            let result = error.OK;
            result.data = Locale;

            logger.info(result);
            return res.status(200).send(result);
        }
        else {
            logger.warn(error.DATA_NOT_FOUND);
            return res.status(404).send(error.DATA_NOT_FOUND);
        }
    }).catch(function (err) {
        logger.error(err);
        return res.status(500).send(error.SERVER_ERROR);
    });
},

Better simplified extension function thanks to ADev

fun ImageView.setTint(@ColorRes colorRes: Int) {
    ImageViewCompat.setImageTintList(this, ColorStateList.valueOf(ContextCompat.getColor(context, colorRes)))
}

Usage:-

imageView.setTint(R.color.tintColor)

There's a DOM method called scrollIntoView, which is supported by all major browsers, that will align an element with the top/left of the viewport (or as close as possible).

$("#myImage")[0].scrollIntoView();

On supported browsers, you can provide options:

$("#myImage")[0].scrollIntoView({
    behavior: "smooth", // or "auto" or "instant"
    block: "start" // or "end"
});

Alternatively, if all the elements have unique IDs, you can just change the hash property of the location object for back/forward button support:

$(document).delegate("img", function (e) {
    if (e.target.id)
        window.location.hash = e.target.id;
});

After that, just adjust the scrollTop/scrollLeft properties by -20:

document.body.scrollLeft -= 20;
document.body.scrollTop -= 20;

In simple words

$.ajax("info.txt").done(function(data) {
  alert(data);
}).fail(function(data){
  alert("Try again champ!");
});

if its get the info.text then it will alert and whatever function you add or if any how unable to retrieve info.text from the server then alert or error function.

new ArrayList( Arrays.asList( new String[]{"abc", "def"} ) );

Update 2018

There is no need for extra CSS, and there are multiple centering methods in Bootstrap 4:

• text-center for center display:inline elements
• mx-auto for centering display:block elements inside display:flex (d-flex)
• offset-* or mx-auto can be used to center grid columns
• or justify-content-center on row to center grid columns

mx-auto (auto x-axis margins) will center inside display:flex elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various centering methods.

In your case, you can simply mx-auto to the cards.

DELETE

The DELETE command is used to remove rows from a table. A WHERE clause can be used to only remove some rows. If no WHERE condition is specified, all rows will be removed. After performing a DELETE operation you need to COMMIT or ROLLBACK the transaction to make the change permanent or to undo it.

TRUNCATE

TRUNCATE removes all rows from a table. The operation cannot be rolled back ... As such, TRUCATE is faster and doesn't use as much undo space as a DELETE.

From: http://www.orafaq.com/faq/difference_between_truncate_delete_and_drop_commands

If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:

sudo mv geckodriver /usr/local/bin

And it should work.

Using the currently recommended (as of 2015) APIs (per the Node docs), this is what I do:

var fs = require('fs');

function fileExists(filePath)
{
    try
    {
        return fs.statSync(filePath).isFile();
    }
    catch (err)
    {
        return false;
    }
}

In response to the EPERM issue raised by @broadband in the comments, that brings up a good point. fileExists() is probably not a good way to think about this in many cases, because fileExists() can't really promise a boolean return. You may be able to determine definitively that the file exists or doesn't exist, but you may also get a permissions error. The permissions error doesn't necessarily imply that the file exists, because you could lack permission to the directory containing the file on which you are checking. And of course there is the chance you could encounter some other error in checking for file existence.

So my code above is really doesFileExistAndDoIHaveAccessToIt(), but your question might be doesFileNotExistAndCouldICreateIt(), which would be completely different logic (that would need to account for an EPERM error, among other things).

While the fs.existsSync answer addresses the question asked here directly, that is often not going to be what you want (you don't just want to know if "something" exists at a path, you probably care about whether the "thing" that exists is a file or a directory).

The bottom line is that if you're checking to see if a file exists, you are probably doing that because you intend to take some action based on the result, and that logic (the check and/or subsequent action) should accommodate the idea that a thing found at that path may be a file or a directory, and that you may encounter EPERM or other errors in the process of checking.

I hit this error ("stat /bin/bash: no such file or directory") when running the command:

docker exec -it 80372bc2c41e /bin/bash

The solution was to identify the kind of terminal (or shell) that is available on the container. To do so, I ran:

docker inspect 80372bc2c41e

In the output from that command, I saw:

"Cmd": [
    "/bin/sh",
    "-c",
    "gunicorn -b 0.0.0.0:7082 server.app:app"
],

This tells me that there's a /bin/sh command available, and I was able to connect with:

docker exec -it 80372bc2c41e /bin/sh

The solving is very simple

var my_obj = {1:[Array-Data], 2:[Array-Data]}
Object.keys(my_obj).map(function(property_name){ 
    return my_obj[property_name]; 
});

Simply change the build-version from compile 'com.android.support:appcompat-v7:26.0.0'

to

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'

This will solve your problem.

A possible solution:

SELECT Company.Company_Id,Company.Company_Name,
    Invoice_Details.Invoice_No, Product_Details.Price
  FROM Company inner join Invoice_Details
    ON Company.Company_Id=Invoice_Details.Company_Id
 INNER JOIN Product_Details
        ON Invoice_Details.Invoice_No= Product_Details.Invoice_No
 WHERE Price='60000';

-- tets changes

Well without converting the integer to a string you could make a funky loop:

var number = 20000;
var length = 0;
for(i = number; i > 1; ++i){
     ++length;
     i = Math.floor(i/10);
}

alert(length);?

I used concat method and works well.

concat(//SomeElement/text(),'_',//OtherElement/text())

Maybe you could abstract this as a dependency and create an IVirtualPathResolver. This way your service classes wouldn't be bound to System.Web and you could create another implementation if you wanted to reuse your logic in a different UI technology.

Using netsh with connectaddress=127.0.0.1 did not work for me.

Despite looking everywhere on the internet I could not find the solution which solved this for me, which was to use connectaddress=127.x.x.x (i.e. any 127. ipv4 address, just not 127.0.0.1) as this appears to link back to localhost just the same but without the restriction, so that the loopback works in netsh.

I have briefly discussed this question in a table so you can conclude whether to go with InnoDB or MyISAM.

Here is a small overview of which db storage engine you should use in which situation:

                                                 MyISAM   InnoDB
----------------------------------------------------------------
Required full-text search                        Yes      5.6.4
----------------------------------------------------------------
Require transactions                                      Yes
----------------------------------------------------------------
Frequent select queries                          Yes      
----------------------------------------------------------------
Frequent insert, update, delete                           Yes
----------------------------------------------------------------
Row locking (multi processing on single table)            Yes
----------------------------------------------------------------
Relational base design                                    Yes

Summary

• In almost all circumstances, InnoDB is the best way to go
• But, frequent reading, almost no writing, use MyISAM
• Full-text search in MySQL <= 5.5, use MyISAM

My Source: http://htmlhelp.com/tools/validator/problems.html#amp

Another common error occurs when including a URL which contains an ampersand ("&"):

This is invalid:

a href="foo.cgi?chapter=1&section=2&copy=3&lang=en"

Explanation:

This example generates an error for "unknown entity section" because the "&" is assumed to begin an entity reference. Browsers often recover safely from this kind of error, but real problems do occur in some cases. In this example, many browsers correctly convert &copy=3 to ©=3, which may cause the link to fail. Since ⟨ is the HTML entity for the left-pointing angle bracket, some browsers also convert &lang=en to <=en. And one old browser even finds the entity §, converting &section=2 to §ion=2.

So the goal here is to avoid problems when you are trying to validate your website. So you should be replacing your ampersands with & when writing a URL in your markup.

Note that replacing & with &amp; is only done when writing the URL in HTML, where "&" is a special character (along with "<" and ">"). When writing the same URL in a plain text email message or in the location bar of your browser, you would use "&" and not "&". With HTML, the browser translates "&" to "&" so the Web server would only see "&" and not "&" in the query string of the request.

Hope this helps : )

Try this:

sed -i 's/\s*$//' youfile.txt

You can do this using Escape Sequence.

\"

So you will have to write something like this :

String name = "\"john\"";

You can learn about Escape Sequences from here.

It is a generic type constraint. In this case it means that the generic type T has to be a reference type (class, interface, delegate, or array type).

I usually use something like this:

>>> s = "string. With. Punctuation?" # Sample string
>>> import string
>>> for c in string.punctuation:
...     s= s.replace(c,"")
...
>>> s
'string With Punctuation'

update q
set q.QuestionID = a.QuestionID
from QuestionTrackings q
inner join QuestionAnswers a
on q.AnswerID = a.AnswerID
where q.QuestionID is null -- and other conditions you might want

I recommend to check what the result set to update is before running the update (same query, just with a select):

select *
from QuestionTrackings q
inner join QuestionAnswers a
on q.AnswerID = a.AnswerID
where q.QuestionID is null -- and other conditions you might want

Particularly whether each answer id has definitely only 1 associated question id.

I use this custom binding (based on this fiddle by RP Niemeyer, see his answer to this question), which makes sure the numeric value is properly converted from string to number (as suggested by the solution of Michael Best):

Javascript:

ko.bindingHandlers.valueAsNumber = {
    init: function (element, valueAccessor, allBindingsAccessor) {
        var observable = valueAccessor(),
            interceptor = ko.computed({
                read: function () {
                    var val = ko.utils.unwrapObservable(observable);
                    return (observable() ? observable().toString() : observable());
                },
                write: function (newValue) {
                    observable(newValue ? parseInt(newValue, 10) : newValue);
                },
                owner: this
            });
        ko.applyBindingsToNode(element, { value: interceptor });
    }
};

Example HTML:

<select data-bind="valueAsNumber: level, event:{ change: $parent.permissionChanged }">
    <option value="0"></option>
    <option value="1">R</option>
    <option value="2">RW</option>
</select>

Yes, you can configure the Spring servlet context xml file to define your beans (i.e., classes), so that it can do the automatic injection for you. However, do note, that you have to do other configurations to have Spring up and running and the best way to do that, is to follow a tutorial ground up.

Once you have your Spring configured probably, you can do the following in your Spring servlet context xml file for Example 1 above to work (please replace the package name of com.movies to what the true package name is and if this is a 3rd party class, then be sure that the appropriate jar file is on the classpath) :

<beans:bean id="movieFinder" class="com.movies.MovieFinder" />

or if the MovieFinder class has a constructor with a primitive value, then you could something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg value="100" />
</beans:bean>

or if the MovieFinder class has a constructor expecting another class, then you could do something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg ref="otherBeanRef" />
</beans:bean>

...where 'otherBeanRef' is another bean that has a reference to the expected class.

This is speed-optimized solution for converting int (signed 16-bit integer) into string.

This implementation avoids using division since 8-bit AVR used for Arduino has no hardware DIV instruction, the compiler translate division into time-consuming repetitive subtractions. Thus the fastest solution is using conditional branches to build the string.

A fixed 7 bytes buffer prepared from beginning in RAM to avoid dynamic allocation. Since it's only 7 bytes, the cost of fixed RAM usage is considered minimum. To assist compiler, we add register modifier into variable declaration to speed-up execution.

char _int2str[7];
char* int2str( register int i ) {
  register unsigned char L = 1;
  register char c;
  register boolean m = false;
  register char b;  // lower-byte of i
  // negative
  if ( i < 0 ) {
    _int2str[ 0 ] = '-';
    i = -i;
  }
  else L = 0;
  // ten-thousands
  if( i > 9999 ) {
    c = i < 20000 ? 1
      : i < 30000 ? 2
      : 3;
    _int2str[ L++ ] = c + 48;
    i -= c * 10000;
    m = true;
  }
  // thousands
  if( i > 999 ) {
    c = i < 5000
      ? ( i < 3000
          ? ( i < 2000 ? 1 : 2 )
          :   i < 4000 ? 3 : 4
        )
      : i < 8000
        ? ( i < 6000
            ? 5
            : i < 7000 ? 6 : 7
          )
        : i < 9000 ? 8 : 9;
    _int2str[ L++ ] = c + 48;
    i -= c * 1000;
    m = true;
  }
  else if( m ) _int2str[ L++ ] = '0';
  // hundreds
  if( i > 99 ) {
    c = i < 500
      ? ( i < 300
          ? ( i < 200 ? 1 : 2 )
          :   i < 400 ? 3 : 4
        )
      : i < 800
        ? ( i < 600
            ? 5
            : i < 700 ? 6 : 7
          )
        : i < 900 ? 8 : 9;
    _int2str[ L++ ] = c + 48;
    i -= c * 100;
    m = true;
  }
  else if( m ) _int2str[ L++ ] = '0';
  // decades (check on lower byte to optimize code)
  b = char( i );
  if( b > 9 ) {
    c = b < 50
      ? ( b < 30
          ? ( b < 20 ? 1 : 2 )
          :   b < 40 ? 3 : 4
        )
      : b < 80
        ? ( i < 60
            ? 5
            : i < 70 ? 6 : 7
          )
        : i < 90 ? 8 : 9;
    _int2str[ L++ ] = c + 48;
    b -= c * 10;
    m = true;
  }
  else if( m ) _int2str[ L++ ] = '0';
  // last digit
  _int2str[ L++ ] = b + 48;
  // null terminator
  _int2str[ L ] = 0;  
  return _int2str;
}

// Usage example:
int i = -12345;
char* s;
void setup() {
  s = int2str( i );
}
void loop() {}

This sketch is compiled to 1,082 bytes of code using avr-gcc which bundled with Arduino v1.0.5 (size of int2str function itself is 594 bytes). Compared with solution using String object which compiled into 2,398 bytes, this implementation can reduce your code size by 1.2 Kb (assumed that you need no other String's object method, and your number is strict to signed int type).

This function can be optimized further by writing it in proper assembler code.

"[a-zA-Z]" matches only one character. To match multiple characters, use "[a-zA-Z]+".

Since a dot is a joker for any character, you have to mask it: "abc\." To make the dot optional, you need a question mark: "abc\.?"

If you write the Pattern as literal constant in your code, you have to mask the backslash:

System.out.println ("abc".matches ("abc\\.?"));
System.out.println ("abc.".matches ("abc\\.?"));
System.out.println ("abc..".matches ("abc\\.?"));

Combining both patterns:

System.out.println ("abc.".matches ("[a-zA-Z]+\\.?"));

Instead of a-zA-Z, \w is often more appropriate, since it captures foreign characters like äöüßø and so on:

System.out.println ("abc.".matches ("\\w+\\.?"));   

DateTime dateValue;
CultureInfo culture = CultureInfo.CurrentCulture;
DateTimeStyles styles = DateTimeStyles.None;
DateTime.TryParse(datetimestring,culture, styles, out dateValue);

There are a couple of things that need to be adjusted in your layout:

1. You are nesting col elements within form-group elements. This should be the other way around (the form-group should be within the col-sm-xx element).

2. You should always use a row div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12 is still on the same row with the above 3 .col-sm-4 resulting in a total of columns greater than 12, and causing the overlap problem.

Here is a fixed demo.

And an excerpt of what the problematic section HTML should become:

<fieldset>
    <legend>Personal Information</legend>
    <div class='row'>
        <div class='col-sm-4'>    
            <div class='form-group'>
                <label for="user_title">Title</label>
                <input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_firstname">First name</label>
                <input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_lastname">Last name</label>
                <input class="form-control" id="user_lastname" name="user[lastname]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
    <div class='row'>
        <div class='col-sm-12'>
            <div class='form-group'>

                <label for="user_email">Email</label>
                <input class="form-control required email" id="user_email" name="user[email]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
</fieldset>

I had the same issue and I solved by doing the following:

1. removing the old tools ($ sudo rm -rf /Library/Developer/CommandLineTools)
2. install xcode command line tools again ($ xcode-select --install).

After these steps you will see a pop to install the new version of the tools.

Following is a Java-Spark way to do it , 1) add a sequentially increment columns. 2) Select Row number using Id. 3) Drop the Column

import static org.apache.spark.sql.functions.*;
..

ds = ds.withColumn("rownum", functions.monotonically_increasing_id());
ds = ds.filter(col("rownum").equalTo(99));
ds = ds.drop("rownum");

N.B. monotonically_increasing_id starts from 0;

This should work:

var matches = text.match(/\[(\d+)\][(\d+)\]/);
var productId = matches[1];
var shopId = matches[2];

I just want to add what solved this problem for me, as it is different to all of the above answers.

The ajax calls that were causing the problem were trying to pass an empty data object. It seems IE does not like this, but other browsers don't mind.

To fix it I simply removed data: {}, from the ajax call.

It is similar to your table

  <table border=1 width=50%>
<tr>
    <td rowspan="2">x</td> 
    <td colspan="4">y</td>
</tr>
<tr>
    <td bgcolor=#FFFF00 >I</td>
    <td>II</td>
    <td bgcolor=#FFFF00>III</td>
    <td>IV</td>
</tr>
<tr>
    <td>empty</td>
    <td bgcolor=#FFFF00>1</td>
    <td>2</td>
    <td bgcolor=#FFFF00>3</td>
    <td>4</td>
</tr>

well you are returning an array of items from the database. so you need something like this.

   $dave= mysql_query("SELECT order_date, no_of_items, shipping_charge, 
    SUM(total_order_amount) as test FROM `orders` 
    WHERE DATE(`order_date`) = DATE(NOW()) GROUP BY DATE(`order_date`)") 
    or  die(mysql_error());


while ($row = mysql_fetch_assoc($dave)) {
echo $row['order_date'];
echo $row['no_of_items'];
echo $row['shipping_charge'];
echo $row['test '];
}

to allow periods and any other character just add them like so:

change: '#[^a-zA-Z ]#' to:'#[^a-zA-Z .()!]#'

As per François Noël's answer "For those who still can't make this work, make sure that the overflowed element is displayed before using the jQuery function."

I had been working in a bootstrap modal that I repeatedly bring up with account permissions in a div that overflows on the y dimension. My problem was, I was trying to use the jquery .scrollTop(0) function and it would not work no matter how I tried to do it. I had to setup an event for the modal that didn't reset the scrollbar until the modal had stopped animating. The code that finally worked for me is here:

    $('#add-modal').on('shown.bs.modal', function (e) {
        $('div.border').scrollTop(0);
    });

Tail-call optimization is where you are able to avoid allocating a new stack frame for a function because the calling function will simply return the value that it gets from the called function. The most common use is tail-recursion, where a recursive function written to take advantage of tail-call optimization can use constant stack space.

Scheme is one of the few programming languages that guarantee in the spec that any implementation must provide this optimization, so here are two examples of the factorial function in Scheme:

(define (fact x)
  (if (= x 0) 1
      (* x (fact (- x 1)))))

(define (fact x)
  (define (fact-tail x accum)
    (if (= x 0) accum
        (fact-tail (- x 1) (* x accum))))
  (fact-tail x 1))

The first function is not tail recursive because when the recursive call is made, the function needs to keep track of the multiplication it needs to do with the result after the call returns. As such, the stack looks as follows:

(fact 3)
(* 3 (fact 2))
(* 3 (* 2 (fact 1)))
(* 3 (* 2 (* 1 (fact 0))))
(* 3 (* 2 (* 1 1)))
(* 3 (* 2 1))
(* 3 2)
6

In contrast, the stack trace for the tail recursive factorial looks as follows:

(fact 3)
(fact-tail 3 1)
(fact-tail 2 3)
(fact-tail 1 6)
(fact-tail 0 6)
6

As you can see, we only need to keep track of the same amount of data for every call to fact-tail because we are simply returning the value we get right through to the top. This means that even if I were to call (fact 1000000), I need only the same amount of space as (fact 3). This is not the case with the non-tail-recursive fact, and as such large values may cause a stack overflow.

The display:table family of CSS properties is mostly there so that HTML tables can be defined in terms of them. Because they're so intimately linked to a specific tag structure, they don't see much use beyond that.

If you were going to use these properties in your page, you would need a tag structure that closely mimicked that of tables, even though you weren't actually using the <table> family of tags. A minimal version would be a single container element (display:table), with direct children that can all be represented as rows (display:table-row), which themselves have direct children that can all be represented as cells (display:table-cell). There are other properties that let you mimic other tags in the table family, but they require analogous structures in the HTML. Without this, it's going to be very hard (if not impossible) to make good use of these properties.

Although side_effect can achieve the goal, it is not so convenient to setup side_effect function for each test case.

I write a lightweight Mock (which is called NextMock) to enhance the built-in mock to address this problem, here is a simple example:

from nextmock import Mock

m = Mock()

m.with_args(1, 2, 3).returns(123)

assert m(1, 2, 3) == 123
assert m(3, 2, 1) != 123

It also supports argument matcher:

from nextmock import Arg, Mock

m = Mock()

m.with_args(1, 2, Arg.Any).returns(123)

assert m(1, 2, 1) == 123
assert m(1, 2, "123") == 123

Hope this package could make testing more pleasant. Feel free to give any feedback.

I actually use a makefile to build any dependencies needed before invoking devenv to build a particular project as in the following:

debug: coratools_debug
    devenv coralib.vcproj /build debug

coratools_debug: nothing
    cd ../coratools
    nmake debug
    cd $(MAKEDIR)

You can also use the msbuild tool to do the same thing:

debug: coratools_debug
    msbuild coralib.vcxproj /p:Configuration=debug

coratools_debug: nothing
    cd ../coratools
    nmake debug
    cd $(MAKEDIR)

In my opinion, this is much easier than trying to figure out the overly complicated visual studio project management scheme.

Another method to extract a substring

library(stringr)
substring <- str_extract(string, regex("(?<=:).*"))
#[1] "E001" "E002" "E003

• (?<=:): look behind the colon (:)

Another option is to apply a transform to the control. However, it will scale down everything including the control borders.

segmentedControl.transform = CGAffineTransformMakeScale(.6f, .6f);

As Hrishikesh Kale has explained we need to pass the Access-Control-Expose-Headers.

Here how we can do it in the WebAPI/MVC environment:

protected void Application_BeginRequest()
        {
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                //These headers are handling the "pre-flight" OPTIONS call sent by the browser
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "*");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Credentials", "true");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "http://localhost:4200");
                HttpContext.Current.Response.AddHeader("Access-Control-Expose-Headers", "TestHeaderToExpose");
                HttpContext.Current.Response.End();
            }
        }

Another way is we can add code as below in the webApiconfig.cs file.

config.EnableCors(new EnableCorsAttribute("", headers: "", methods: "*",exposedHeaders: "TestHeaderToExpose") { SupportsCredentials = true });

**We can add custom headers in the web.config file as below. *

<httpProtocol>
   <customHeaders>
      <add name="Access-Control-Expose-Headers" value="TestHeaderToExpose" />
   </customHeaders>
</httpProtocol>

we can create an attribute and decore the method with the attribute.

Happy Coding !!

If you have the environment variables in an env.sh locally and want to set it up when the container starts, you could try

COPY env.sh /env.sh
COPY <filename>.jar /<filename>.jar
ENTRYPOINT ["/bin/bash" , "-c", "source /env.sh && printenv && java -jar /<filename>.jar"]

This command would start the container with a bash shell (I want a bash shell since source is a bash command), sources the env.sh file(which sets the environment variables) and executes the jar file.

The env.sh looks like this,

#!/bin/bash
export FOO="BAR"
export DB_NAME="DATABASE_NAME"

I added the printenv command only to test that actual source command works. You should probably remove it when you confirm the source command works fine or the environment variables would appear in your docker logs.

Use this code with a closure (introduced in PHP 5.3), it's a bit faster than the accepted answer and for me, the intention to cast it to an integer, is clearer:

// if you have your values in the format '1,2,3,4', use this before:
// $stringArray = explode(',', '1,2,3,4');

$stringArray = ['1', '2', '3', '4'];

$intArray = array_map(
    function($value) { return (int)$value; },
    $stringArray
);

var_dump($intArray);

Output will be:

array(4) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
}

One way of doing that is by using trap DEBUG:

f() { bash -c "$BASH_COMMAND" >& /tmp/out.log; }
trap 'f' DEBUG

Now most recently executed command's stdout and stderr will be available in /tmp/out.log

Only downside is that it will execute a command twice: once to redirect output and error to /tmp/out.log and once normally. Probably there is some way to prevent this behavior as well.

The 2 concurrent requests is an intentional part of the design of many browsers. There is a standard out there that "good http clients" adhere to on purpose. Check out this RFC to see why.

Unfortunately none of these answers solved the specific problem I had.

Here's a simple solution without having to mess with bash. In my case, it was getting gradle to work (for Android Studio).

Btw, These steps relate to OSX (Mountain Lion 10.8.5)

• Open up Terminal.

• Run the following command:

  sudo nano /etc/paths (or sudo vim /etc/paths for vim)

  

• Go to the bottom of the file, and enter the path you wish to add.
• Hit control-x to quit.
• Enter 'Y' to save the modified buffer.

• Open a new terminal window then type:

  echo $PATH

You should see the new path appended to the end of the PATH

I got these details from this post:

I hope that can help someone else

My first suggestion is to use Designer to create your GUIs. Typing them out yourself sucks, takes more time, and you will definitely make more mistakes than Designer.

Here are some PyQt tutorials to help get you on the right track. The first one in the list is where you should start.

A good guide for figuring out what methods are available for specific classes is the PyQt4 Class Reference. In this case you would look up QLineEdit and see the there is a text method.

To answer your specific question:

To make your GUI elements available to the rest of the object, preface them with self.

import sys
from PyQt4.QtCore import SIGNAL
from PyQt4.QtGui import QDialog, QApplication, QPushButton, QLineEdit, QFormLayout

class Form(QDialog):
    def __init__(self, parent=None):
        super(Form, self).__init__(parent)

        self.le = QLineEdit()
        self.le.setObjectName("host")
        self.le.setText("Host")

        self.pb = QPushButton()
        self.pb.setObjectName("connect")
        self.pb.setText("Connect") 

        layout = QFormLayout()
        layout.addWidget(self.le)
        layout.addWidget(self.pb)

        self.setLayout(layout)
        self.connect(self.pb, SIGNAL("clicked()"),self.button_click)
        self.setWindowTitle("Learning")

    def button_click(self):
        # shost is a QString object
        shost = self.le.text()
        print shost


app = QApplication(sys.argv)
form = Form()
form.show()
app.exec_()

Your item variable holds Array instance (in [hash_key, hash_value] format), so it doesn't expect Symbol in [] method.

This is how you could do it using Hash#each:

def format(hash)
  output = Hash.new
  hash.each do |key, value|
    output[key] = cleanup(value)
  end
  output
end

or, without this:

def format(hash)
  output = hash.dup
  output[:company_name] = cleanup(output[:company_name])
  output[:street] = cleanup(output[:street])
  output
end

Firstly, as @l33tnerd said, f.close should be outside the for loop.

Secondly, you are only calling readline once, before the loop. That only reads the first line. The trick is that in Python, files act as iterators, so you can iterate over the file without having to call any methods on it, and that will give you one line per iteration:

 if data.find('!masters') != -1:
     f = open('masters.txt')
     for line in f:
           print line,
           sck.send('PRIVMSG ' + chan + " " + line)
     f.close()

Finally, you were referring to the variable lines inside the loop; I assume you meant to refer to line.

Edit: Oh and you need to indent the contents of the if statement.

You can use the ImageLocation property of pictureBox1:

pictureBox1.ImageLocation = @"C:\Users\MSI\Desktop\MYAPP\Slider\Slider\bt1.jpg";

You can use which.

x<-c(1:5)
x
#[1] 1 2 3 4 5
x<-x[-which(x==4)]
x
#[1] 1 2 3 5

The <select> tag creates a dropdown list. You can't put html links inside a dropdown.

However, there are JavaScript libraries that provide similar functionality. Here is one example: http://www.dynamicdrive.com/dynamicindex1/dropmenuindex.htm

There are many good scripts above for generating insert statements, but I attempted one of my own to make it as user friendly as possible and to also be able to do UPDATE statements. + package the result ready for .sql files that can be stored by date.

It takes as input your normal SELECT statement with WHERE clause, then outputs a list of Insert statements and update statements. Together they form a sort of IF NOT EXISTS () INSERT ELSE UPDATE It is handy too when there are non-updatable columns that need exclusion from the final INSERT/UPDATE statement.

Another thing that below script can do is: it can even handle INNER JOINs with other tables as input statement for the stored proc. It can be handy as a poor man's Release management tool that sits right at your finger tips where you are typing the sql SELECT statements all day.

-------------README for the deeper interested person:
            Goal of the Stored PROCEDURE is to get updates from simple SQL SELECT statements. It is made ot be simple but fast and powerfull. As always => power is nothing without control, so check before you execute.
            Its power sits also in the fact that you can make insert statements, so combined gives you a  "IF NOT EXISTS()  INSERT "   capability. 

            The scripts work were there are primary keys or identity columns on table you want to update (/ or make inserts for).
            It will also works when no primary keys / identity column exist(s) and you define them yourselve. But then be carefull (duplicate hits can occur). When the table has a primary key it will always be used.
            The script works with a real  temporary table, made on the fly   (APPROPRIATE RIGHTS needed), to put the values inside from the script, then add 3 columns for constructing the "insert into tableX (...) values ()" ,  and the 2 update statement.
            We work with temporary structures like   "where columnname = {Columnname}" and then later do the update on that temptable for the columns values found on that same line.
                    example  "where columnname = {Columnname}"  for birthdate becomes   "where birthdate = {birthdate}" an then we find the birthdate value on that line inside the temp table.
            So then the statement becomes  "where birthdate = {19800417}"
            Enjoy releasing scripts as of now...                                        by  Pieter van Nederkassel  - freeware "CC BY-SA" (+use at own risk)

Here is the same problem.

You need to set table-layout:fixed and a suitable width on the table element, as well as overflow:hidden and white-space: nowrap on the table cells.

Examples

Fixed width columns

The width of the table has to be the same (or smaller) than the fixed width cell(s).

With one fixed width column:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
  max-width: 100px;
}
td {
  background: #F00;
  padding: 20px;
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
  border: solid 1px #000;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

With multiple fixed width columns:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
  max-width: 200px;
}
td {
  background: #F00;
  padding: 20px;
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
  border: solid 1px #000;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

Fixed and fluid width columns

A width for the table must be set, but any extra width is simply taken by the fluid cell(s).

With multiple columns, fixed width and fluid width:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  background: #F00;
  padding: 20px;
  border: solid 1px #000;
}
tr td:first-child {
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

I wrote this method to replace characters or replace strings at a specific instance. instances start at 0 (this can easily be changed to 1 if you change the optional inst argument to 1, and test_instance variable to 1.

def replace_instance(some_word, str_to_replace, new_str='', inst=0):
    return_word = ''
    char_index, test_instance = 0, 0
    while char_index < len(some_word):
        test_str = some_word[char_index: char_index + len(str_to_replace)]
        if test_str == str_to_replace:
            if test_instance == inst:
                return_word = some_word[:char_index] + new_str + some_word[char_index + len(str_to_replace):]
                break
            else:
                test_instance += 1
        char_index += 1
    return return_word

Here is solution for dynamic queries.

For example if you have more tables with different suffix:

dbo.SOMETHINGTABLE_ONE, dbo.SOMETHINGTABLE_TWO

Code:

DECLARE @INDEX AS NVARCHAR(20)
DECLARE @CheckVALUE AS NVARCHAR(max) = 'SELECT COUNT(SOMETHING) FROM 
dbo.SOMETHINGTABLE_'+@INDEX+''
DECLARE @tempTable Table (TempVALUE int)
DECLARE @RESULTVAL INT

INSERT INTO @tempTable
    EXEC sp_executesql @CheckVALUE

SET @RESULTVAL = (SELECT * FROM @tempTable)

DELETE @tempTable

SELECT @RESULTVAL 

Add the ng command path from the folder .bin under the node_modules to PATH variable in the system env settings.

e.g: add C:\testProject\node_modules\.bin\ to PATH

Restart your IDE.

If you want to load the file without running it through the webserver, the following should work.

$string = eval(file_get_contents("file.php"));

This will load then evaluate the file contents. The PHP file will need to be fully formed with <?php and ?> tags for eval to evaluate it.

If you want to initialize some compound type (f.e. string) you can do something like that:

class SomeClass {
  static std::list<string> _list;

  public:
    static const std::list<string>& getList() {
      struct Initializer {
         Initializer() {
           // Here you may want to put mutex
           _list.push_back("FIRST");
           _list.push_back("SECOND");
           ....
         }
      }
      static Initializer ListInitializationGuard;
      return _list;
    }
};

As the ListInitializationGuard is a static variable inside SomeClass::getList() method it will be constructed only once, which means that constructor is called once. This will initialize _list variable to value you need. Any subsequent call to getList will simply return already initialized _list object.

Of course you have to access _list object always by calling getList() method.

After enough googling I found the answer from controller you need only a backslash like return \Response::json(['success' => 'hi, atiq']); . Or you can just return the array return array('success' => 'hi, atiq'); which will be rendered as json in Laravel version 5.2 .

Though the earlier answers are correct, there's a small complication it would help to remark on.

In case your main module imports another module in which global variables or class member variables are defined and initialized to (or using) some new objects, you may have to condition that import in the same way:

if __name__ ==  '__main__':
  import my_module

It's always enlightening to do a benchmark on the various suggested answers. Here's what I found out:

#!/usr/bin/ruby

require 'benchmark'

ary = []
1000.times { 
  ary << {:bar => rand(1000)} 
}

n = 500
Benchmark.bm(20) do |x|
  x.report("sort")               { n.times { ary.sort{ |a,b| b[:bar] <=> a[:bar] } } }
  x.report("sort reverse")       { n.times { ary.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse } }
  x.report("sort_by -a[:bar]")   { n.times { ary.sort_by{ |a| -a[:bar] } } }
  x.report("sort_by a[:bar]*-1") { n.times { ary.sort_by{ |a| a[:bar]*-1 } } }
  x.report("sort_by.reverse!")   { n.times { ary.sort_by{ |a| a[:bar] }.reverse } }
end

                          user     system      total        real
sort                  3.960000   0.010000   3.970000 (  3.990886)
sort reverse          4.040000   0.000000   4.040000 (  4.038849)
sort_by -a[:bar]      0.690000   0.000000   0.690000 (  0.692080)
sort_by a[:bar]*-1    0.700000   0.000000   0.700000 (  0.699735)
sort_by.reverse!      0.650000   0.000000   0.650000 (  0.654447)

I think it's interesting that @Pablo's sort_by{...}.reverse! is fastest. Before running the test I thought it would be slower than "-a[:bar]" but negating the value turns out to take longer than it does to reverse the entire array in one pass. It's not much of a difference, but every little speed-up helps.

Please note that these results are different in Ruby 1.9

Here are results for Ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin10.8.0]:

                           user     system      total        real

sort reverse           1.300000   0.000000   1.300000 (  1.310446)

sort_by.reverse!       0.400000   0.000000   0.400000 (  0.401275)

These are on an old MacBook Pro. Newer, or faster machines, will have lower values, but the relative differences will remain.

Here's a bit updated version on newer hardware and the 2.1.1 version of Ruby:

#!/usr/bin/ruby

require 'benchmark'

1000.times {
  ary << {:bar => rand(1000)}

  x.report("sort")               { n.times { ary.dup.sort{ |a,b| b[:bar] <=> a[:bar] } } }
  x.report("sort reverse")       { n.times { ary.dup.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse } }
  x.report("sort_by -a[:bar]")   { n.times { ary.dup.sort_by{ |a| -a[:bar] } } }
  x.report("sort_by a[:bar]*-1") { n.times { ary.dup.sort_by{ |a| a[:bar]*-1 } } }
  x.report("sort_by.reverse")    { n.times { ary.dup.sort_by{ |a| a[:bar] }.reverse } }
  x.report("sort_by.reverse!")   { n.times { ary.dup.sort_by{ |a| a[:bar] }.reverse! } }
end

...the reverse method doesn't actually return a reversed array - it returns an enumerator that just starts at the end and works backwards.

The source for Array#reverse is:

               static VALUE
rb_ary_reverse_m(VALUE ary)
{
    long len = RARRAY_LEN(ary);
    VALUE dup = rb_ary_new2(len);

    if (len > 0) {
        const VALUE *p1 = RARRAY_CONST_PTR_TRANSIENT(ary);
        VALUE *p2 = (VALUE *)RARRAY_CONST_PTR_TRANSIENT(dup) + len - 1;
        do *p2-- = *p1++; while (--len > 0);
    }
    ARY_SET_LEN(dup, RARRAY_LEN(ary));
    return dup;
}

do *p2-- = *p1++; while (--len > 0); is copying the pointers to the elements in reverse order if I remember my C correctly, so the array is reversed.

figlegend may be what you're looking for: http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.figlegend

Example here: http://matplotlib.org/examples/pylab_examples/figlegend_demo.html

Another example:

plt.figlegend( lines, labels, loc = 'lower center', ncol=5, labelspacing=0. )

or:

fig.legend( lines, labels, loc = (0.5, 0), ncol=5 )

After a lot of searching the web and trying to find the most suitable form for routing map if have found the following

config.Routes.MapHttpRoute("DefaultApiWithId", "Api/{controller}/{id}", new { id =RouteParameter.Optional }, new { id = @"\d+" });
config.Routes.MapHttpRoute("DefaultApiWithAction", "Api/{controller}/{action}");

These mapping applying to both action name mapping and basic http convention (GET,POST,PUT,DELETE)

i believe what you're looking for is the str.encode("string-escape") function. For example, if you have a variable that you want to 'raw string':

a = '\x89'
a.encode('unicode_escape')
'\\x89'

Note: Use string-escape for python 2.x and older versions

I was searching for a similar solution and found the solution via: casting raw strings python

If you are using Spring, add an argument of type @RequestParam Map<String,String> to your controller method, and Spring will construct the map for you!

In your build.gradle(Module:app), add android-gif-drawable as a dependency by adding the following code:

allprojects {
    repositories {
       mavenCentral()
    }
}

dependencies {
    compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
}

dependencies {
    implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
}

Then sync your project. When synchronization ends, go to your layout file and add the following code:

<pl.droidsonroids.gif.GifImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/gif_file"
/>

And that's it, you can manage it with a simple ImageView.

Unable to run vagrant up because it gets stuck and times out? I recently had a "water in laptop incident" and had to migrate to a new one(on a MAC by the way). I successfully got all my projects up and running beside the one, which was using vagrant.

    default: Warning: Authentication failure. Retrying...

It couldn't authenticate, retried again and again and eventually gave up.

This is how I got it back in shape in 3 steps:

1 - Find the IdentityFile used by Vagrant:

$ vagrant ssh-config

Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile /Users/ned/.vagrant.d/insecure_private_key
  IdentitiesOnly yes
  LogLevel FATAL

2 - Check the public key in the IdentityFile:

$ ssh-keygen -y -f <path-to-insecure_private_key>

It'd output something like this:

ssh-rsa AAAAB3Nyc2EAAA...9gE98OHlnVYCzRdK8jlqm8hQ==

3 - Log in to the Vagrant guest with the password vagrant:

ssh -p 2222 -o UserKnownHostsFile=/dev/null [email protected]

The authenticity of host '[127.0.0.1]:2222 ([127.0.0.1]:2222)' can't be established.
RSA key fingerprint is dc:48:73:c3:18:e4:9d:34:a2:7d:4b:20:6a:e7:3d:3e.

...

NOTE: if vagrant guest is configured to disallow password authentication you need to open VBox' GUI, double click guest name, login as vagrant/vagrant, then sudo -s and edit /etc/ssh/sshd_config and look for PasswordAuthentication no line (usually at the end of the file), replace no with yes and restart sshd (i.e. systemctl reload sshd or /etc/init.d/sshd restart).

4 - Add the public key to the /home/vagrant/authorized_keys file.

$ echo "ssh-rsa AA2EAAA...9gEdK8jlqm8hQ== vagrant" > /home/vagrant/.ssh/authorized_keys

5 - Exit (CTRL+d) and stop the Vagrant guest and then bring it back up.

IMPORTANT if you use any provisioning tools (i.e. Ansible etc) disable it before restarting your guest as Vagrant will think your guest is not provisioned because of use of insecure private key. It will reinstall the key and then run your provisioner!

$ vagrant halt
$ vagrant up

Hopefully you will have your arms in the air now...

I got this, with just a minor amend, from Ned Batchelders article - Ned you are a champ!

The Change event gets called even if you click on cancel..

The only way I can think that you can accomplish what you want purely with css, is to use a fluid container for your widget. If your container's width is a percentage of the screen then you can use media queries to style depending on your container's width, as you will now know for each screen's dimensions what is your container's dimensions. For example, let's say you decide to make your container's 50% of the screen width. Then for a screen width of 1200px you know that your container is 600px

.myContainer {
  width: 50%;
}

/* you know know that your container is 600px 
 * so you style accordingly
*/
@media (max-width: 1200px) { 
  /* your css for 600px container */
}

<span style="color:#ffffff; font-size:18px; line-height:35px; font-family: Calibri;">Our Activities </span>

This works for me well:) As it has been already mentioned above "The font tag has been deprecated, at least in XHTML. It always safe to use span tag. font may not give you desire results, at least in my case it didn't.

One way to live-stream a RTSP-based webcam to a HTML5 client (involves re-encoding, so expect quality loss and needs some CPU-power):

• Set up an icecast server (could be on the same machine you web server is on or on the machine that receives the RTSP-stream from the cam)

• On the machine receiving the stream from the camera, don't use FFMPEG but gstreamer. It is able to receive and decode the RTSP-stream, re-encode it and stream it to the icecast server. Example pipeline (only video, no audio):

  gst-launch-1.0 rtspsrc location=rtsp://192.168.1.234:554 user-id=admin user-pw=123456 ! rtph264depay ! avdec_h264 ! vp8enc threads=2 deadline=10000 ! webmmux streamable=true ! shout2send password=pass ip=<IP_OF_ICECAST_SERVER> port=12000 mount=cam.webm
  

=> You can then use the <video> tag with the URL of the icecast-stream (http://127.0.0.1:12000/cam.webm) and it will work in every browser and device that supports webm

I just was in about the same situation a day ago, and here are my 2 cents:

1) I found arguably the shortest and most concise demonstration of multiple model entry in single form here: http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ .

In a nutshell: Make a form for each model, submit them both to template in a single <form>, using prefix keyarg and have the view handle validation. If there is dependency, just make sure you save the "parent" model before dependant, and use parent's ID for foreign key before commiting save of "child" model. The link has the demo.

2) Maybe formsets can be beaten into doing this, but as far as I delved in, formsets are primarily for entering multiples of the same model, which may be optionally tied to another model/models by foreign keys. However, there seem to be no default option for entering more than one model's data and that's not what formset seems to be meant for.

A more cross-browser solution… I hope the gist of this helps someone out there.

This solution tries to set the type attribute, and if it fails, it simply creates a new <input> element, preserving element attributes and event handlers.

changeTypeAttr.js (GitHub Gist):

/* x is the <input/> element
   type is the type you want to change it to.
   jQuery is required and assumed to be the "$" variable */
function changeType(x, type) {
    x = $(x);
    if(x.prop('type') == type)
        return x; //That was easy.
    try {
        return x.prop('type', type); //Stupid IE security will not allow this
    } catch(e) {
        //Try re-creating the element (yep... this sucks)
        //jQuery has no html() method for the element, so we have to put into a div first
        var html = $("<div>").append(x.clone()).html();
        var regex = /type=(\")?([^\"\s]+)(\")?/; //matches type=text or type="text"
        //If no match, we add the type attribute to the end; otherwise, we replace
        var tmp = $(html.match(regex) == null ?
            html.replace(">", ' type="' + type + '">') :
            html.replace(regex, 'type="' + type + '"') );
        //Copy data from old element
        tmp.data('type', x.data('type') );
        var events = x.data('events');
        var cb = function(events) {
            return function() {
                //Bind all prior events
                for(i in events)
                {
                    var y = events[i];
                    for(j in y)
                        tmp.bind(i, y[j].handler);
                }
            }
        }(events);
        x.replaceWith(tmp);
        setTimeout(cb, 10); //Wait a bit to call function
        return tmp;
    }
}

Void doesn't return anything; it tells the compiler the method doesn't have a return value.

RandomStringUtils from Apache commons-lang might help:

RandomStringUtils.randomAlphanumeric(17).toUpperCase()

2017 update: RandomStringUtils has been deprecated, you should now use RandomStringGenerator.

Step 1:Make sure you are on path actual workspace.For example, workspace/blog $: Step2:Enter the command: gem install bundler. Step 3: You should be all set to bundle install or bundle update by now

Base on the question, I use this script below to automatic increase my version number in all maven parent/submodules:

#!/usr/bin/env bash  

# Advances the last number of the given version string by one.  
function advance\_version () {  
    local v=$1  
    \# Get the last number. First remove any suffixes (such as '-SNAPSHOT').  
  local cleaned=\`echo $v | sed \-e 's/\[^0-9\]\[^0-9\]\*$//'\`  
 local last\_num=\`echo $cleaned | sed \-e 's/\[0-9\]\*\\.//g'\`  
 local next\_num=$(($last\_num+1))  
  \# Finally replace the last number in version string with the new one.  
  echo $v | sed \-e "s/\[0-9\]\[0-9\]\*\\(\[^0-9\]\*\\)$/$next\_num/"  
}  

version=$(mvn org.apache.maven.plugins:maven-help-plugin:3.2.0:evaluate -Dexpression=project.version -q -DforceStdout)  

new\_version=$(advance\_version $version)  

mvn versions:set -DnewVersion=${new\_version} -DprocessAllModules -DgenerateBackupPoms=false

BE VERY CAREFUL, the problem may come from multibytes encoding and inappropriate PHP functions used...

It was the case for me and it took me a while to figure it out.

For example, I get the a string from MySQL using utf8mb4 (very common now to encode emojis):

$formattedString = strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WILL RETURN THE ERROR 'Detected an illegal character in input string'

The problem does not stand in iconv() but stands in strtolower() in this case.

The appropriate way is to use Multibyte String Functions mb_strtolower() instead of strtolower()

$formattedString = mb_strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WORK FINE

MORE INFO

More examples of this issue are available at this SO answer

PHP Manual on the Multibyte String

The other answers were incorrect, at least in my case. request.path does not provide the full url, only the relative url, e.g. /paper/53. I did not find any proper solution, so I ended up hardcoding the constant part of the url in the View before concatenating it with request.path.

Have a look at this plunker:: this is the simplest example i could think of

http://jsfiddle.net/HEdJF/

<div ng-app="myApp">
    <div ng-controller="FirstCtrl">
        <input type="text" ng-model="Data.FirstName"><!-- Input entered here -->
        <br>Input is : <strong>{{Data.FirstName}}</strong><!-- Successfully updates here -->
    </div>
    <hr>
    <div ng-controller="SecondCtrl">
        Input should also be here: {{Data.FirstName}}<!-- How do I automatically updated it here? -->
    </div>
</div>



// declare the app with no dependencies
var myApp = angular.module('myApp', []);
myApp.factory('Data', function(){
   return { FirstName: '' };
});

myApp.controller('FirstCtrl', function( $scope, Data ){
    $scope.Data = Data;
});

myApp.controller('SecondCtrl', function( $scope, Data ){
    $scope.Data = Data;
});

ALTER TABLE users
  ADD COLUMN "priv_user" BOOLEAN DEFAULT FALSE;

you can also directly specify NOT NULL

ALTER TABLE users
  ADD COLUMN "priv_user" BOOLEAN NOT NULL DEFAULT FALSE;

UPDATE: following is only true for versions before postgresql 11.

As Craig mentioned on filled tables it is more efficient to split it into steps:

ALTER TABLE users ADD COLUMN priv_user BOOLEAN;
UPDATE users SET priv_user = 'f';
ALTER TABLE users ALTER COLUMN priv_user SET NOT NULL;
ALTER TABLE users ALTER COLUMN priv_user SET DEFAULT FALSE;

Solution without using extra ArrayList or combination of add() and remove() methods. Both can have negative impact if you have to reverse a huge list.

 public ArrayList<Object> reverse(ArrayList<Object> list) {

   for (int i = 0; i < list.size() / 2; i++) {
     Object temp = list.get(i);
     list.set(i, list.get(list.size() - i - 1));
     list.set(list.size() - i - 1, temp);
   }

   return list;
 }

Since this would be a common task I would suggest wrapping a switch/case inside of a function call.

function getVocationName($vocation){
    switch($vocation){
        case 1: return "Sorcerer";
        case 2: return 'Druid';
        case 3: return 'Paladin';
        case 4: return 'Knight';
        case 5: return 'Master Sorcerer';
        case 6: return 'Elder Druid';
        case 7: return 'Royal Paladin';
        default: return 'Elite Knight';
    }
}

echo getVocationName($result->vocation);

The action attribute will default to the current URL. It is the most reliable and easiest way to say "submit the form to the same place it came from".

There is no reason to use $_SERVER['PHP_SELF'], and # doesn't submit the form at all (unless there is a submit event handler attached that handles the submission).

just replace

file_get_contents

with

$ip = $_SERVER['xxx.xxx.xxx.xxx'];
exec("ping -n 4 $ip 2>&1", $output, $retval);
if ($retval != 0) { 
  echo "no!"; 
} 
else{ 
  echo "yes!"; 
}

All of the Func delegates take at least one parameter

That's not true. They all take at least one type argument, but that argument determines the return type.

So Func<T> accepts no parameters and returns a value. Use Action or Action<T> when you don't want to return a value.

$string_val = 'a.b';

$parts = explode('.', $string_val);

print_r($parts);

Docs: http://us.php.net/manual/en/function.explode.php

You can also use the actual text of the *e*xample test case with -e !

So for:

it "shows the plane arrival time"

you can use

rspec path/to/spec/file.rb -e 'shows the plane arrival time'
./scripts/spec path/to/spec/file.rb -e 'shows the plane arrival time'

no need for rake here.

You can do this with reflection. Specifically, you can use the ReflectionClass::getShortName method, which gets the name of the class without its namespace.

First, you need to build a ReflectionClass instance, and then call the getShortName method of that instance:

$reflect = new ReflectionClass($object);
if ($reflect->getShortName() === 'Name') {
    // do this
}

However, I can't imagine many circumstances where this would be desirable. If you want to require that the object is a member of a certain class, the way to test it is with instanceof. If you want a more flexible way to signal certain constraints, the way to do that is to write an interface and require that the code implement that interface. Again, the correct way to do this is with instanceof. (You can do it with ReflectionClass, but it would have much worse performance.)

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

First, HTML and PDF are not related although they were created around the same time. HTML is intended to convey higher level information such as paragraphs and tables. Although there are methods to control it, it is ultimately up to the browser to draw these higher level concepts. PDF is intended to convey documents and the documents must "look" the same wherever they are rendered.

In an HTML document you might have a paragraph that's 100% wide and depending on the width of your monitor it might take 2 lines or 10 lines and when you print it it might be 7 lines and when you look at it on your phone it might take 20 lines. A PDF file, however, must be independent of the rendering device, so regardless of your screen size it must always render exactly the same.

Because of the musts above, PDF doesn't support abstract things like "tables" or "paragraphs". There are three basic things that PDF supports: text, lines/shapes and images. (There are other things like annotations and movies but I'm trying to keep it simple here.) In a PDF you don't say "here's a paragraph, browser do your thing!". Instead you say, "draw this text at this exact X,Y location using this exact font and don't worry, I've previously calculated the width of the text so I know it will all fit on this line". You also don't say "here's a table" but instead you say "draw this text at this exact location and then draw a rectangle at this other exact location that I've previously calculated so I know it will appear to be around the text".

Second, iText and iTextSharp parse HTML and CSS. That's it. ASP.Net, MVC, Razor, Struts, Spring, etc, are all HTML frameworks but iText/iTextSharp is 100% unaware of them. Same with DataGridViews, Repeaters, Templates, Views, etc. which are all framework-specific abstractions. It is your responsibility to get the HTML from your choice of framework, iText won't help you. If you get an exception saying The document has no pages or you think that "iText isn't parsing my HTML" it is almost definite that you don't actually have HTML, you only think you do.

Third, the built-in class that's been around for years is the HTMLWorker however this has been replaced with XMLWorker (Java / .Net). Zero work is being done on HTMLWorker which doesn't support CSS files and has only limited support for the most basic CSS properties and actually breaks on certain tags. If you do not see the HTML attribute or CSS property and value in this file then it probably isn't supported by HTMLWorker. XMLWorker can be more complicated sometimes but those complications also make it more extensible.

Below is C# code that shows how to parse HTML tags into iText abstractions that get automatically added to the document that you are working on. C# and Java are very similar so it should be relatively easy to convert this. Example #1 uses the built-in HTMLWorker to parse the HTML string. Since only inline styles are supported the class="headline" gets ignored but everything else should actually work. Example #2 is the same as the first except it uses XMLWorker instead. Example #3 also parses the simple CSS example.

2017's update

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation this year, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

At first, I put childView1 above childView2 and I want childView1 to be on top of childView2. Changing the order of children views did not solve the problem for me. What worked for me is to set android:clipChildren="false" on parentView and in the code I set:

childView1.bringToFront();

parentView.invalidate();

Using the std::vector<T> class:

• ...is just as fast as using built-in arrays, assuming you are doing only the things built-in arrays allow you to do (read and write to existing elements).

• ...automatically resizes when new elements are inserted.

• ...allows you to insert new elements at the beginning or in the middle of the vector, automatically "shifting" the rest of the elements "up"( does that make sense?). It allows you to remove elements anywhere in the std::vector, too, automatically shifting the rest of the elements down.

• ...allows you to perform a range-checked read with the at() method (you can always use the indexers [] if you don't want this check to be performed).

There are two three main caveats to using std::vector<T>:

1. You don't have reliable access to the underlying pointer, which may be an issue if you are dealing with third-party functions that demand the address of an array.

2. The std::vector<bool> class is silly. It's implemented as a condensed bitfield, not as an array. Avoid it if you want an array of bools!

3. During usage, std::vector<T>s are going to be a bit larger than a C++ array with the same number of elements. This is because they need to keep track of a small amount of other information, such as their current size, and because whenever std::vector<T>s resize, they reserve more space then they need. This is to prevent them from having to resize every time a new element is inserted. This behavior can be changed by providing a custom allocator, but I never felt the need to do that!

Edit: After reading Zud's reply to the question, I felt I should add this:

The std::array<T> class is not the same as a C++ array. std::array<T> is a very thin wrapper around C++ arrays, with the primary purpose of hiding the pointer from the user of the class (in C++, arrays are implicitly cast as pointers, often to dismaying effect). The std::array<T> class also stores its size (length), which can be very useful.

I had the same issue and this helped me.

<ImageView
    android:id="@+id/image"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:scaleType="fitXY"
    />

You can also use google-collections (guava) Joiner class if you want to customize the print format

I am using Python 3.6 and using a comma between Exception and e does not work. I need to use the following syntax (just for anyone wondering)

try:
    connection = manager.connect("I2Cx")
except KeyError as e:
    print(e.message)

If you do know the maximal length of a line, you can do

def getLastLine(fname, maxLineLength=80):
    fp=file(fname, "rb")
    fp.seek(-maxLineLength-1, 2) # 2 means "from the end of the file"
    return fp.readlines()[-1]

This works on my windows machine. But I do not know what happens on other platforms if you open a text file in binary mode. The binary mode is needed if you want to use seek().

It seems daft, but I think when you use the same bind variable twice you have to set it twice:

cmd.Parameters.Add("VarA", "24");
cmd.Parameters.Add("VarB", "test");
cmd.Parameters.Add("VarB", "test");
cmd.Parameters.Add("VarC", "1234");
cmd.Parameters.Add("VarC", "1234");

Certainly that's true with Native Dynamic SQL in PL/SQL:

SQL> begin
  2     execute immediate 'select * from emp where ename=:name and ename=:name'
  3     using 'KING';
  4  end;
  5  /
begin
*
ERROR at line 1:
ORA-01008: not all variables bound


SQL> begin
  2     execute immediate 'select * from emp where ename=:name and ename=:name' 
  3     using 'KING', 'KING';
  4  end;
  5  /

PL/SQL procedure successfully completed.

Try the code

awk '{s=($3==0)?"-":$3/$4; print s}'

maybe this help :

declare 
@statement AS NVARCHAR(MAX)
,@text1 varchar(50)='hello'
,@text2 varchar(50)='world'

set @statement = '
select '''+@text1+''' + '' beautifull '' + ''' + @text2 + ''' 
'
exec sp_executesql @statement;

this is same as below :

select @text1 + ' beautifull ' + @text2

tl;dr

LocalDateTime.parse( 
    "2012-07-10 14:58:00.000000".replace( " " , "T" )  
)

Microseconds do not fit

You are attempting to squeeze a value with microseconds (six decimal digits) into a data type capable only of milliseconds resolution (three decimal digits). That is impossible.

Instead, use a data type with fine enough resolution. The java.time classes use nanosecond resolution (nine decimal digits).

Unzoned input does not fit a zoned type

You are attempting to put a value lacking any offset-from-UTC or time zone into a data type (Date) that only represents values in UTC. So you are adding information (UTC offset) not intended by the input.

Use an appropriate data type instead. Specifically, java.time.LocalDateTime.

Case-sensitive

Other Answers and Comments correctly explain that the formatting pattern codes are case-sensitive. So MM and mm have different effects.

Avoid legacy classes

The troublesome old date-time classes bundled with the earliest versions of Java are now legacy, supplanted by the java.time classes built into Java 8 and later.

ISO 8601

Your input strings nearly comply with the ISO 8601 standard formats. Replace the SPACE in the middle with a T to comply fully.

The java.time classes use the standard formats by default when parsing/generating strings. So no need to specify a formatting pattern.

Date-time objects have no "format"

and I need the resultant date object to be of the same format.

No, date-time objects do not have a "format". Do not conflate date-time objects with mere strings. Strings are inputs and outputs of the objects. The objects maintain their own internal representions of the date-time info, the details of which are irrelevant to us as calling programmers.

java.time

Your input lacks any indicator of offset-from-UTC or troublesome me zone. So we parse as a LocalDateTime objects which lacks those concepts.

String input = "2012-07-10 14:58:00.000000".replace( " " , "T" ) ;
LocalDateTime ldt = LocalDateTime.parse( input ) ;

Generating strings

To generate a String representing the value of your LocalDateTime:

• Call toString to get a String in standard ISO 8601 format.
• Use DateTimeFormatter for producing strings in either custom formats or automatically-localized formats.

Search Stack Overflow for more info as these topics have been covered many many times already.

ZonedDateTime

A LocalDateTime does not represent an exact point on the timeline.

To determine an actual moment, assign a time zone. For example noon in Kolkata India comes much earlier than noon in Paris France. Noon without a time zone could be happening at any point over a range of about 26-27 hours.

ZoneId z = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = ldt.atZone( z ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

WPF takes a slightly different approach than WinForms here. Instead of having the automation of a object built into the API, they have a separate class for each object that is responsible for automating it. In this case you need the ButtonAutomationPeer to accomplish this task.

ButtonAutomationPeer peer = new ButtonAutomationPeer(someButton);
IInvokeProvider invokeProv = peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider;
invokeProv.Invoke();

Here is a blog post on the subject.

Note: IInvokeProvider interface is defined in the UIAutomationProvider assembly.

Actually this will give you repeated indices np.random.random_integers(0, len(df), N) where N is a large number.

Simplest way I could think of: add a class.

Simply add a class (on any element) and check inside the interval if it's there. This is more reliable, customisable and cross-language than any other way, I believe.

var i = 0;_x000D_
this.setInterval(function() {_x000D_
  if(!$('#counter').hasClass('pauseInterval')) { //only run if it hasn't got this class 'pauseInterval'_x000D_
    console.log('Counting...');_x000D_
    $('#counter').html(i++); //just for explaining and showing_x000D_
  } else {_x000D_
    console.log('Stopped counting');_x000D_
  }_x000D_
}, 500);_x000D_
_x000D_
/* In this example, I'm adding a class on mouseover and remove it again on mouseleave. You can of course do pretty much whatever you like */_x000D_
$('#counter').hover(function() { //mouse enter_x000D_
    $(this).addClass('pauseInterval');_x000D_
  },function() { //mouse leave_x000D_
    $(this).removeClass('pauseInterval');_x000D_
  }_x000D_
);_x000D_
_x000D_
/* Other example */_x000D_
$('#pauseInterval').click(function() {_x000D_
  $('#counter').toggleClass('pauseInterval');_x000D_
});

body {_x000D_
  background-color: #eee;_x000D_
  font-family: Calibri, Arial, sans-serif;_x000D_

  margin: 0 auto;_x000D_
}_x000D_
#counter.pauseInterval {_x000D_
  border-color: red;  _x000D_
}

<!-- you'll need jQuery for this. If you really want a vanilla version, ask -->_x000D_

Another formula option is to use REPLACE function to replace the first n characters with nothing, e.g. if n = 4

=REPLACE(A1,1,4,"")

You are going to need to call the SmsManager class. You are probably going to need to use the STATUS_ON_ICC_READ constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through. BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.

Here is the link that goes into depth on the Sms Manager

What is wrong with using string.Length?

// len will be 5

Strange nobody listed an actual command to do it:

mvn help:describe -e -Dplugin=site

If you want to list all goals of the site plugin. Output:

Name: Apache Maven Site Plugin Description: The Maven Site Plugin is a plugin that generates a site for the current project. Group Id: org.apache.maven.plugins Artifact Id: maven-site-plugin Version: 3.7.1 Goal Prefix: site

This plugin has 9 goals:

site:attach-descriptor Description: Adds the site descriptor (site.xml) to the list of files to be installed/deployed. For Maven-2.x this is enabled by default only when the project has pom packaging since it will be used by modules inheriting, but this can be enabled for other projects packaging if needed. This default execution has been removed from the built-in lifecycle of Maven 3.x for pom-projects. Users that actually use those projects to provide a common site descriptor for sub modules will need to explicitly define this goal execution to restore the intended behavior.

site:deploy Description: Deploys the generated site using wagon supported protocols to the site URL specified in the section of the POM. For scp protocol, the website files are packaged by wagon into zip archive, then the archive is transfered to the remote host, next it is un-archived which is much faster than making a file by file copy.

site:effective-site Description: Displays the effective site descriptor as an XML for this build, after inheritance and interpolation of site.xml, for the first locale.

site:help Description: Display help information on maven-site-plugin. Call mvn site:help -Ddetail=true -Dgoal= to display parameter details.

site:jar Description: Bundles the site output into a JAR so that it can be deployed to a repository.

site:run Description: Starts the site up, rendering documents as requested for faster editing. It uses Jetty as the web server.

site:site Description: Generates the site for a single project. Note that links between module sites in a multi module build will not work, since local build directory structure doesn't match deployed site.

site:stage Description: Deploys the generated site to a local staging or mock directory based on the site URL specified in the section of the POM. It can be used to test that links between module sites in a multi-module build work.

This goal requires the site to already have been generated using the site goal, such as by calling mvn site.

site:stage-deploy Description: Deploys the generated site to a staging or mock URL to the site URL specified in the section of the POM, using wagon supported protocols

For more information, run 'mvn help:describe [...] -Ddetail'

In My example call add function from button click event and then get value from form control's and call function generateTable.
In generateTable Function check first Table is Generaed or not. If table is undefined then call generateHeader Funtion and Generate Header and then call addToRow function for adding new row in table.

<input type="button" class="custom-rounded-bttn bttn-save" value="Add" id="btnAdd" onclick="add()">


<div class="row">
    <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
        <div class="dataGridForItem">
        </div>
    </div>
</div>

//Call Function From Button click Event

var counts = 1;
function add(){ 
    var Weightage = $('#Weightage').val();
    var ItemName = $('#ItemName option:selected').text();  
    var ItemNamenum = $('#ItemName').val();
    generateTable(Weightage,ItemName,ItemNamenum);
     $('#Weightage').val('');
     $('#ItemName').val(-1);
     return true;
 } 


function generateTable(Weightage,ItemName,ItemNamenum){
    var tableHtml = '';
    if($("#rDataTable").html() == undefined){
        tableHtml = generateHeader();
    }else{
        tableHtml = $("#rDataTable");
    } 
    var temp = $("<div/>");
    var row = addToRow(Weightage,ItemName,ItemNamenum);
    $(temp).append($(row));
    $("#dataGridForItem").html($(tableHtml).append($(temp).html()));
}


//Generate Header


function generateHeader(){
        var html = "<table id='rDataTable' class='table table-striped'>";
        html+="<tr class=''>";
        html+="<td class='tb-heading ui-state-default'>"+'Sr.No'+"</td>";
        html+="<td class='tb-heading ui-state-default'>"+'Item Name'+"</td>";
        html+="<td class='tb-heading ui-state-default'>"+'Weightage'+"</td>";
        html+="</tr></table>";
        return html; 
}

//Add New Row


function addToRow(Weightage,ItemName,ItemNamenum){
    var html="<tr class='trObj'>";
    html+="<td>"+counts+"</td>";
    html+="<td>"+ItemName+"</td>";
    html+="<td>"+Weightage+"</td>";
    html+="</tr>";
    counts++;
    return html;
}

If you use log without base it uses e.

From the comment

Return the logarithm of x to the given base.
If the base not specified, returns the natural logarithm (base e) of x.

Therefor you have to use:

import math
print( math.log(1.5, 10))

You can use filter:

filter(lambda x: x.isdigit(), "dasdasd2313dsa")

On python3.0 you have to join this (kinda ugly :( )

''.join(filter(lambda x: x.isdigit(), "dasdasd2313dsa"))

ISO-8859-1 is a legacy standards from back in 1980s. It can only represent 256 characters so only suitable for some languages in western world. Even for many supported languages, some characters are missing. If you create a text file in this encoding and try copy/paste some Chinese characters, you will see weird results. So in other words, don't use it. Unicode has taken over the world and UTF-8 is pretty much the standards these days unless you have some legacy reasons (like HTTP headers which needs to compatible with everything).

There are different ways to check Oracle Database Version. Easiest way is to run the below SQL query to check Oracle Version.

SQL> SELECT * FROM PRODUCT_COMPONENT_VERSION;

SQL> SELECT * FROM v$version;

On linux ubuntu 20.04 I needed few steps,downgrade node first to apropriate version,remove node_modules,run yarn install and finally run sudo yarn add [email protected] --force.Node version 10.0.0. Only working way for me.

The previous answers show 3 approaches

1. By creating a new data frame
2. By using "cbind"
3. By adding column "a", and sort data frame by columns using column names or indexes

Let me show #4 approach "By using "cbind" and "rename" that works for my case

1. Create data frame

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))

2. Get values for "new" column

new_column = c(0, 0, 0)

3. Combine "new" column with existed

df <- cbind(new_column, df)

4. Rename "new" column name

colnames(df)[1] <- "a"

You need to merge the remote branch into your current branch by running git pull.

If your local branch is already up-to-date, you may also need to run git pull --rebase.

A quick google search also turned up this same question asked by another SO user: Cannot push to GitHub - keeps saying need merge. More details there.

Git Fetch

Helps you to get known about the latest updates from a git repository. Let's say you working in a team using GitFlow, where team working on multiple branches ( features ). With git fetch --all command you can get known about all new branches within repository.

Mostly git fetch is used with git reset. For example you want to revert all your local changes to the current repository state.

git fetch --all // get known about latest updates
git reset --hard origin/[branch] // revert to current branch state

Git pull

This command update your branch with current repository branch state. Let's continue with GitFlow. Multiple feature branches was merged to develop branch and when you want to develop new features for the project you must go to the develop branch and do a git pull to get the current state of develop branch

Using the minus operator was working but also it was taking more time to execute which was not acceptable. I have a similar kind of requirement for data migration and I used the NOT IN operator for that. The modified query is :

select * 
from A 
where (emp_id,emp_name) not in 
   (select emp_id,emp_name from B) 
   union all 
select * from B 
where (emp_id,emp_name) not in 
   (select emp_id,emp_name from A); 

This query executed fast. Also you can add any number of columns in the select query. Only catch is that both tables should have the exact same table structure for this to be executed.

Ok, here's a simple box that follows the cursor

Doing the rest is a simple case of remembering the last cursor position and applying a formula to get the box to move other than exactly where the cursor is. A timeout would also be handy if the box has a limited acceleration and must catch up to the cursor after it stops moving. Replacing the box with an image is simple CSS (which can replace most of the setup code for the box). I think the actual thinking code in the example is about 8 lines.

Select the right image (use a sprite) to orientate the rocket.

lots of methods available in php to read a file like exec, file_get_contents, curl and fopen but it depend on your requirement and file permission

Visit this file_get_contents vs cUrl

Basically file_get_contents for for you

$data = file_get_contents($file_url);

To do that you should do:

a =  [5, 7, 11, 4, 5]
for i in range(len(a)-1):
    print [a[i], a[i+1]]

Using a check for newkey!=oldkey, this way you can do:

if newkey!=oldkey:  
    dictionary[newkey] = dictionary[oldkey]
    del dictionary[oldkey]

Nathan's answer will give you jokes from last 24, 168, and 744 hours, NOT the jokes from today, this week, this month. If that's what you want, great, but I think you might be looking for something different.

Using his code, at noon, you will get the jokes beginning yesterday at noon, and ending today at noon. If you really want today's jokes, try the following:

SELECT * FROM jokes WHERE date >= CURRENT_DATE() ORDER BY score DESC;  

You would have to do something a little different from current week, month, etc., but you get the idea.

It's an indication that connection pooling is being used (which is a good thing).

This should do the trick

export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get -q -y install mysql-server

Of course, it leaves you with a blank root password - so you'll want to run something like

mysqladmin -u root password mysecretpasswordgoeshere

Afterwards to add a password to the account.

Issue is that it is failed to decrypt 256 bits of encryption.

If you just want to change the size font dynamically then you can:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, resources.getDimension(R.dimen.tutorial_cross_marginTop))

As @achie's answer, you can get the dp from dimens.xml like this:

val dpValue = (resources.getDimension(R.dimen.tutorial_cross_marginTop)/ resources.displayMetrics.density).toInt()

or get sp like this

val spValue = (resources.getDimension(R.dimen.font_size)/ resources.displayMetrics.scaledDensity).toInt()

About Resources.java #{getDimension}

    /**
     * Retrieve a dimensional for a particular resource ID.  Unit 
     * conversions are based on the current {@link DisplayMetrics} associated
     * with the resources.
     * 
     * @param id The desired resource identifier, as generated by the aapt
     *           tool. This integer encodes the package, type, and resource
     *           entry. The value 0 is an invalid identifier.
     * 
     * @return Resource dimension value multiplied by the appropriate 
     * metric.
     * 
     * @throws NotFoundException Throws NotFoundException if the given ID does not exist.
     *
     * @see #getDimensionPixelOffset
     * @see #getDimensionPixelSize
     */

Resource dimension value multiplied by the appropriate

Another alternative. I prefer this approach because it is less writing but the two accomplish the same thing.

IF COLUMNPROPERTY(OBJECT_ID('dbo.Person'), 'ColumnName', 'ColumnId') IS NULL
BEGIN
    ALTER TABLE Person 
    ADD ColumnName VARCHAR(MAX) NOT NULL
END

I also noticed yours is looking for where table does exist that is obviously just this

 if COLUMNPROPERTY( OBJECT_ID('dbo.Person'),'ColumnName','ColumnId') is not null

For some reason AngularJS allows to get me confused. Their documentation is pretty horrible on this. More good examples of variations would be welcome.

Anyway, I have a slight variation on Ben Lesh's answer.

My data collections looks like this:

items =
[
   { key:"AD",value:"Andorra" }
,  { key:"AI",value:"Anguilla" }
,  { key:"AO",value:"Angola" }
 ...etc..
]

Now

<select ng-model="countries" ng-options="item.key as item.value for item in items"></select>

still resulted in the options value to be the index (0, 1, 2, etc.).

Adding Track By fixed it for me:

<select ng-model="blah" ng-options="item.value for item in items track by item.key"></select>

I reckon it happens more often that you want to add an array of objects into an select list, so I am going to remember this one!

Be aware that from AngularJS 1.4 you can't use ng-options any more, but you need to use ng-repeat on your option tag:

<select name="test">
   <option ng-repeat="item in items" value="{{item.key}}">{{item.value}}</option>
</select>

Here is the BESTEST way to send emails using PHPmailer library, this is the only method that works for me.

require_once 'mailer/class.phpmailer.php';
    $mail = new PHPMailer(); // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true; // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465; // or 587
    $mail->IsHTML(true);
    $mail->Username = "[email protected]";
    $mail->Password = "xxxxxxx";
    $mail->SetFrom("[email protected]");
    $mail->AddAddress($to);
    $logfile = dirname(dirname(__FILE__)) . '/mail.log';
    try {
        $mail->Body = $message;
        $mail->Subject = $subject;


        file_put_contents($logfile, "Content: \n", FILE_APPEND);
        file_put_contents($logfile, $message . "\n\n", FILE_APPEND);

        if(!$mail->Send()) {
            echo "Mailer Error: " . $mail->ErrorInfo;
        } else {
            echo "Email has been sent";
        }
    } catch (Exception $e) {
        #print_r($e->getMessage());
        file_put_contents($logfile, "Error: \n", FILE_APPEND);
        file_put_contents($logfile, $e->getMessage() . "\n", FILE_APPEND);
        file_put_contents($logfile, $e->getTraceAsString() . "\n\n", FILE_APPEND);
    }

The HTTP specification (RFC 2616) has a number of recommendations that are applicable. Here is my interpretation:

• HTTP status code 200 OK for a successful PUT of an update to an existing resource. No response body needed. (Per Section 9.6, 204 No Content is even more appropriate.)
• HTTP status code 201 Created for a successful PUT of a new resource, with the most specific URI for the new resource returned in the Location header field and any other relevant URIs and metadata of the resource echoed in the response body. (RFC 2616 Section 10.2.2)
• HTTP status code 409 Conflict for a PUT that is unsuccessful due to a 3^rd-party modification, with a list of differences between the attempted update and the current resource in the response body. (RFC 2616 Section 10.4.10)
• HTTP status code 400 Bad Request for an unsuccessful PUT, with natural-language text (such as English) in the response body that explains why the PUT failed. (RFC 2616 Section 10.4)

body {
    margin: 0;
    padding: 0;
    background: url('img/background.jpg') repeat;
}

I think this is the right way :

git merge --abort

git fetch --all

Then, you have two options:

git reset --hard origin/master

OR If you are on some other branch:

git reset --hard origin/<branch_name>

I got the same error because of a simple typo in vhost.conf. Remember to make sure you don't have any errors in the config files.

After much pain, and great assistance from @vitr et al above, i decided to try

• standard bash substitution
• shell form of ENTRYPOINT (great tip from above)

and that worked.

ENV LISTEN_PORT=""

ENTRYPOINT java -cp "app:app/lib/*" hello.Application --server.port=${LISTEN_PORT:-80}

e.g.

docker run --rm -p 8080:8080 -d --env LISTEN_PORT=8080 my-image

and

docker run --rm -p 8080:80 -d my-image

both set the port correctly in my container

Refs

see https://www.cyberciti.biz/tips/bash-shell-parameter-substitution-2.html

this works with 0 arguments with gcc/llvm. [links are dumb]

/*
 * we need a comma at the start for ##_VA_ARGS__ to consume then
 * the arguments are pushed out in such a way that 'cnt' ends up with
 * the right count.

#define COUNT_ARGS_(z,a,b,c,d,e,f,cnt,...) cnt

    }

int main() {
   C_ASSERT(0 ==  COUNT_ARGS());
   C_ASSERT(1 ==  COUNT_ARGS(a));
   C_ASSERT(2 ==  COUNT_ARGS(a,b));
   C_ASSERT(3 ==  COUNT_ARGS(a,b,c));

   C_ASSERT(5 ==  COUNT_ARGS(a,b,c,d,e));
   C_ASSERT(6 ==  COUNT_ARGS(a,b,c,d,e,f));
   return 0;
}

Visual Studio seems to be ignoring the ## operator used to consume the empty argument. You can probably get around that with something like

#define CNT_ COUNT_ARGS
#define PASTE(x,y) PASTE_(x,y)
#define PASTE_(x,y) x ## y
#define CNT(...) PASTE(ARGVS,PASTE(CNT_(__VA_ARGS__),CNT_(1,##__VA_ARGS__)))
//you know its 0 if its 11 or 01
#define ARGVS11 0
#define ARGVS01 0
#define ARGVS12 1
#define ARGVS23 2
#define ARGVS34 3

It is worked for me

OK, let me put this bluntly: if you're putting user data, or anything derived from user data into a cookie for this purpose, you're doing something wrong.

There. I said it. Now we can move on to the actual answer.

What's wrong with hashing user data, you ask? Well, it comes down to exposure surface and security through obscurity.

Imagine for a second that you're an attacker. You see a cryptographic cookie set for the remember-me on your session. It's 32 characters wide. Gee. That may be an MD5...

Let's also imagine for a second that they know the algorithm that you used. For example:

md5(salt+username+ip+salt)

Now, all an attacker needs to do is brute force the "salt" (which isn't really a salt, but more on that later), and he can now generate all the fake tokens he wants with any username for his IP address! But brute-forcing a salt is hard, right? Absolutely. But modern day GPUs are exceedingly good at it. And unless you use sufficient randomness in it (make it large enough), it's going to fall quickly, and with it the keys to your castle.

In short, the only thing protecting you is the salt, which isn't really protecting you as much as you think.

But Wait!

All of that was predicated that the attacker knows the algorithm! If it's secret and confusing, then you're safe, right? WRONG. That line of thinking has a name: Security Through Obscurity, which should NEVER be relied upon.

The Better Way

The better way is to never let a user's information leave the server, except for the id.

When the user logs in, generate a large (128 to 256 bit) random token. Add that to a database table which maps the token to the userid, and then send it to the client in the cookie.

What if the attacker guesses the random token of another user?

Well, let's do some math here. We're generating a 128 bit random token. That means that there are:

possibilities = 2^128
possibilities = 3.4 * 10^38

Now, to show how absurdly large that number is, let's imagine every server on the internet (let's say 50,000,000 today) trying to brute-force that number at a rate of 1,000,000,000 per second each. In reality your servers would melt under such load, but let's play this out.

guesses_per_second = servers * guesses
guesses_per_second = 50,000,000 * 1,000,000,000
guesses_per_second = 50,000,000,000,000,000

So 50 quadrillion guesses per second. That's fast! Right?

time_to_guess = possibilities / guesses_per_second
time_to_guess = 3.4e38 / 50,000,000,000,000,000
time_to_guess = 6,800,000,000,000,000,000,000

So 6.8 sextillion seconds...

Let's try to bring that down to more friendly numbers.

215,626,585,489,599 years

Or even better:

47917 times the age of the universe

Yes, that's 47917 times the age of the universe...

Basically, it's not going to be cracked.

So to sum up:

The better approach that I recommend is to store the cookie with three parts.

function onLogin($user) {
    $token = GenerateRandomToken(); // generate a token, should be 128 - 256 bit
    storeTokenForUser($user, $token);
    $cookie = $user . ':' . $token;
    $mac = hash_hmac('sha256', $cookie, SECRET_KEY);
    $cookie .= ':' . $mac;
    setcookie('rememberme', $cookie);
}

Then, to validate:

function rememberMe() {
    $cookie = isset($_COOKIE['rememberme']) ? $_COOKIE['rememberme'] : '';
    if ($cookie) {
        list ($user, $token, $mac) = explode(':', $cookie);
        if (!hash_equals(hash_hmac('sha256', $user . ':' . $token, SECRET_KEY), $mac)) {
            return false;
        }
        $usertoken = fetchTokenByUserName($user);
        if (hash_equals($usertoken, $token)) {
            logUserIn($user);
        }
    }
}

Note: Do not use the token or combination of user and token to lookup a record in your database. Always be sure to fetch a record based on the user and use a timing-safe comparison function to compare the fetched token afterwards. More about timing attacks.

Now, it's very important that the SECRET_KEY be a cryptographic secret (generated by something like /dev/urandom and/or derived from a high-entropy input). Also, GenerateRandomToken() needs to be a strong random source (mt_rand() is not nearly strong enough. Use a library, such as RandomLib or random_compat, or mcrypt_create_iv() with DEV_URANDOM)...

The hash_equals() is to prevent timing attacks. If you use a PHP version below PHP 5.6 the function hash_equals() is not supported. In this case you can replace hash_equals() with the timingSafeCompare function:

/**
 * A timing safe equals comparison
 *
 * To prevent leaking length information, it is important
 * that user input is always used as the second parameter.
 *
 * @param string $safe The internal (safe) value to be checked
 * @param string $user The user submitted (unsafe) value
 *
 * @return boolean True if the two strings are identical.
 */
function timingSafeCompare($safe, $user) {
    if (function_exists('hash_equals')) {
        return hash_equals($safe, $user); // PHP 5.6
    }
    // Prevent issues if string length is 0
    $safe .= chr(0);
    $user .= chr(0);

    // mbstring.func_overload can make strlen() return invalid numbers
    // when operating on raw binary strings; force an 8bit charset here:
    if (function_exists('mb_strlen')) {
        $safeLen = mb_strlen($safe, '8bit');
        $userLen = mb_strlen($user, '8bit');
    } else {
        $safeLen = strlen($safe);
        $userLen = strlen($user);
    }

    // Set the result to the difference between the lengths
    $result = $safeLen - $userLen;

    // Note that we ALWAYS iterate over the user-supplied length
    // This is to prevent leaking length information
    for ($i = 0; $i < $userLen; $i++) {
        // Using % here is a trick to prevent notices
        // It's safe, since if the lengths are different
        // $result is already non-0
        $result |= (ord($safe[$i % $safeLen]) ^ ord($user[$i]));
    }

    // They are only identical strings if $result is exactly 0...
    return $result === 0;
}

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

Remove the : before last-child and the :after and used

 ul li:not(last-child){
 content:' |';
}

Hopefully,it should work

Completeness

You need to check both $mysqli and $statement. If they are false, you need to output $mysqli->error or $statement->error respectively.

Efficiency

For simple scripts that may terminate, I use simple one-liners that trigger a PHP error with the message. For a more complex application, an error warning system should be activated instead, for example by throwing an exception.

Usage example 1: Simple script

# This is in a simple command line script
$mysqli = new mysqli('localhost', 'buzUser', 'buzPassword');
$q = "UPDATE foo SET bar=1";
($statement = $mysqli->prepare($q)) or trigger_error($mysqli->error, E_USER_ERROR);
$statement->execute() or trigger_error($statement->error, E_USER_ERROR);

Usage example 2: Application

# This is part of an application
class FuzDatabaseException extends Exception {
}

class Foo {
  public $mysqli;
  public function __construct(mysqli $mysqli) {
    $this->mysqli = $mysqli;
  }
  public function updateBar() {
    $q = "UPDATE foo SET bar=1";
    $statement = $this->mysqli->prepare($q);
    if (!$statement) {
      throw new FuzDatabaseException($mysqli->error);
    }

    if (!$statement->execute()) {
      throw new FuzDatabaseException($statement->error);
    }
  }
}

$foo = new Foo(new mysqli('localhost','buzUser','buzPassword'));
try {
  $foo->updateBar();
} catch (FuzDatabaseException $e)
  $msg = $e->getMessage();
  // Now send warning emails, write log
}

I know this might not be a complete or exact solution, but for those who are still facing issues even after doing what is given on this thread, check for your files in value folder. For me there was a typo and some missing values. Once i fixed them this error stopped.

UPDATE 2019 (Swift 4):

Made a Date extension for that. It uses NSDataDetector instead of NSDateFormatter.

// Just throw at it without any format.
var date: Date? = Date.FromString("02-14-2019 17:05:05")

Pretty enjoyable, it even recognizes things like "Tomorrow at 5".

XCTAssertEqual(Date.FromString("02-13-2019 Tomorrow"),           Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("2019 Feb 14th Tomorrow at 5"),   Date.FromCalendar(2019, 2, 14, 17))

Goes like:

extension Date
{


    public static func FromString(_ dateString: String) -> Date?
    {
        // Date detector.
        let detector = try! NSDataDetector(types: NSTextCheckingResult.CheckingType.date.rawValue)

        // Enumerate matches.
        var matchedDate: Date?
        var matchedTimeZone: TimeZone?
        detector.enumerateMatches(
            in: dateString,
            options: [],
            range: NSRange(location: 0, length: dateString.utf16.count),
            using:
            {
                (eachResult, _, _) in

                // Lookup matches.
                matchedDate = eachResult?.date
                matchedTimeZone = eachResult?.timeZone

                // Convert to GMT (!) if no timezone detected.
                if matchedTimeZone == nil, let detectedDate = matchedDate
                { matchedDate = Calendar.current.date(byAdding: .second, value: TimeZone.current.secondsFromGMT(), to: detectedDate)! }
        })

        // Result.
        return matchedDate
    }
}

UPDATE 2014:

Made an NSString extension for that.

// Simple as this.   
date = dateString.dateValue;

Thanks to NSDataDetector, it recognizes a whole lot of format.

'2014-01-16' dateValue is <2014-01-16 11:00:00 +0000>
'2014.01.16' dateValue is <2014-01-16 11:00:00 +0000>

ORIGINAL ANSWER 2013:

Whether you're not sure (or don't care) about the date format contained in the string, use NSDataDetector for parsing date.

//Role players.
NSString *dateString = @"Wed, 03 Jul 2013 02:16:02 -0700";
__block NSDate *detectedDate;

//Detect.
NSDataDetector *detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingAllTypes error:nil];
[detector enumerateMatchesInString:dateString
                           options:kNilOptions
                             range:NSMakeRange(0, [dateString length])
                        usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop)
{ detectedDate = result.date; }];

And if you want to vary the speed and include callbacks simply add them like this :

        jQuery.fn.extend({
            slideRightShow: function(speed,callback) {
                return this.each(function() {
                    $(this).show('slide', {direction: 'right'}, speed, callback);
                });
            },
            slideLeftHide: function(speed,callback) {
                return this.each(function() {
                    $(this).hide('slide', {direction: 'left'}, speed, callback);
                });
            },
            slideRightHide: function(speed,callback) {
                return this.each(function() {  
                    $(this).hide('slide', {direction: 'right'}, speed, callback);
                });
            },
            slideLeftShow: function(speed,callback) {
                return this.each(function() {
                    $(this).show('slide', {direction: 'left'}, speed, callback);
                });
            }
        });

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

Try:

git commit -m 'my notes' path/to/my/file.ext 

In my opinion one of the worst chosen word's to describe the process, as it is not related to anything in real-life or similar. In general the word "queue" is very bad as if pronounced, it sounds like the English character "q". See the inefficiency here?

enqueue: to place something into a queue; to add an element to the tail of a queue;

dequeue to take something out of a queue; to remove the first available element from the head of a queue

source: https://www.thefreedictionary.com

If you know the elements that need mouse events, and if your overlay is transparent, you can just set the z-index of them to something higher than the overlay. All events should of course work in that case on all browsers.

the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.

This would also work :

import 'package:http/http.dart' as http;

  sendRequest() async {

    Map data = {
       'apikey': '12345678901234567890'
    };

    var url = 'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
    http.post(url, body: data)
        .then((response) {
      print("Response status: ${response.statusCode}");
      print("Response body: ${response.body}");
    });  
  }

Try C# 7.0

var Dob= DateTime.TryParseExact(s: YourDateString,format: "yyyyMMdd",provider: null,style: 0,out var dt)
 ? dt : DateTime.Parse("1800-01-01");

A good book on Subversion is Pragmatic Version Control using Subversion where your question is explained, and it gives a lot more information.

update for mySQL 8 :

String jdbcUrl="jdbc:mysql://localhost:3306/youdatabase?useSSL=false&serverTimezone=UTC";

Check whether your Jdbc configurations and URL correct or wrong using the following code snippet.

import java.sql.Connection;
import java.sql.DriverManager;

public class TestJdbc {

    public static void main(String[] args) {

        //db name:testdb_version001
        //useSSL=false (get rid of MySQL SSL warnings)

        String jdbcUrl = "jdbc:mysql://localhost:3306/testdb_version001?useSSL=false";
        String username="testdb";
        String password ="testdb";

        try{

            System.out.println("Connecting to database :" +jdbcUrl);
            Connection myConn =
                    DriverManager.getConnection(jdbcUrl,username,password);

            System.out.println("Connection Successful...!");


        }catch (Exception e){
            e.printStackTrace();
            //e.printStackTrace();
        }

    }


}

For those who get this (terribly unclear) error:

COPY failed: stat /var/lib/docker/tmp/docker-builderXXXXXXX/abc.txt: no such file or directory

There could be loads of reasons, including:

• For docker-compose users, remember that the docker-compose.yml context overwrites the context of the Dockerfile. Your COPY statements now need to navigate a path relative to what is defined in docker-compose.yml instead of relative to your Dockerfile.
• Trailing comments or a semicolon on the COPY line: COPY abc.txt /app #This won't work
• The file is in a directory ignored by .dockerignore or .gitignore files (be wary of wildcards)
• You made a typo

Sometimes WORKDIR /abc followed by COPY . xyz/ works where COPY /abc xyz/ fails, but it's a bit ugly.

You have to remove the IMEX=1 if you want to update. ;)

"IMEX=1; tells the driver to always read "intermixed" (numbers, dates, strings etc) data columns as text. Note that this option might affect excel sheet write access negative." https://www.connectionstrings.com/excel/

Do you want to open a shared folder in Windows Explorer? You need to use a file: link, but there are caveats:

• Internet Explorer will work if the link is a converted UNC path (file://server/share/folder/).
• Firefox will work if the link is in its own mangled form using five slashes (file://///server/share/folder) and the user has disabled the security restriction on file: links in a page served over HTTP. Thankfully IE also accepts the mangled link form.
• Opera, Safari and Chrome can not be convinced to open a file: link in a page served over HTTP.

You could implement a ring buffer. Make an array of 1000 elements, and some fields to store the start and end indexes and total size. Then just store the last 1000 elements in the ring buffer, and recalculate the average as needed.

If you want to preserve the details come with ls like file size etc in your output then this should work.

sed "s|<OLDPATH>|<NEWPATH>|g" input_file > output_file

In addition to existing answers I'd like to add that you can also have a class instance available app-wide which holds user-related data like UserID etc.

It may be useful for refactoring e.g. you don't want to fetch UserID in every controller action and declare an extra UserID parameter in every method related to Service Layer.

I've done a research and here's my post.

You just extend your class which you derive from DbContext by adding UserId property (or implement a custom Session class which has this property).

At filter level you can fetch your class instance and set UserId value.

After that wherever you inject your instance - it will have the necessary data (lifetime must be per request, so you register it using AddScoped method).

Working example:

public class AppInitializationFilter : IAsyncActionFilter
{
    private DBContextWithUserAuditing _dbContext;

    public AppInitializationFilter(
        DBContextWithUserAuditing dbContext
        )
    {
        _dbContext = dbContext;
    }

    public async Task OnActionExecutionAsync(
        ActionExecutingContext context,
        ActionExecutionDelegate next
        )
    {
        string userId = null;
        int? tenantId = null;

        var claimsIdentity = (ClaimsIdentity)context.HttpContext.User.Identity;

        var userIdClaim = claimsIdentity.Claims.SingleOrDefault(c => c.Type == ClaimTypes.NameIdentifier);
        if (userIdClaim != null)
        {
            userId = userIdClaim.Value;
        }

        var tenantIdClaim = claimsIdentity.Claims.SingleOrDefault(c => c.Type == CustomClaims.TenantId);
        if (tenantIdClaim != null)
        {
            tenantId = !string.IsNullOrEmpty(tenantIdClaim.Value) ? int.Parse(tenantIdClaim.Value) : (int?)null;
        }

        _dbContext.UserId = userId;
        _dbContext.TenantId = tenantId;

        var resultContext = await next();
    }
}
