You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

\begin{table}
\begin{tabular}{| p{5cm} | p{5cm} | p{5cm} |}
  -- cut --
\end{tabular}
\caption{My table}
\label{table:kysymys}
\end{table}

Table \ref{table:kysymys} on page \pageref{table:kysymys} refers to the ...

Is this what you are after? Just index the element and assign a new value.

A[2,1]=150

A
Out[345]: 
array([[ 1,  2,  3,  4],
       [ 5,  6,  7,  8],
       [ 9, 150, 11, 12],
       [13, 14, 15, 16]])

It is possible.

When you use Return inside a procedure, the control is transferred to the calling program which calls the procedure. It is like an exit in loops.

It won't return any value.

In some cases, you might want to know when the value is specifically null, which is particularly necessary when using XML which has been serialized from .NET objects. While the accepted answer works for this, it also returns the same result when the string is blank or empty, i.e. '', so you can't differentiate.

<group>
    <item>
        <id>item 1</id>
        <CategoryName xsi:nil="true" />
    </item>
</group>

So you can simply test the attribute.

<xsl:if test="CategoryName/@xsi:nil='true'">
   Hello World.
</xsl:if>

Sometimes it's necessary to know the exact state and you can't simply check if CategoryName is instantiated, because unlike say Javascript

<xsl:if test="CategoryName">
   Hello World.
</xsl:if>

Will return true for a null element.

Activation by system properties can be done as follows

<activation>
    <property>
        <name>foo</name>
        <value>bar</value>
    </property>
</activation>

And run the mvn build with -D to set system property

mvn clean install -Dfoo=bar

This method also helps select profiles in transitive dependency of project artifacts.

For others that arrive on this page from google:

DataRow also has a function .IsNull("ColumnName")

    public DateTime? TestDt; 
    public Parse(DataRow row)
    {
        if (!row.IsNull("TEST_DT"))
            TestDt = Convert.ToDateTime(row["TEST_DT"]);
    }

position: relative; has some issues in IE with z-index and animations like jQuery's slideUp/slideDown.

CSS:

input[type=checkbox], input[type=radio] {
    vertical-align: baseline;
    position: relative;
    top: 3px;
    margin: 0 3px 0 0;
    padding: 0px;
}
input.ie7[type=checkbox], input.ie7[type=radio] {
    vertical-align: middle;
    position: static;
    margin-bottom: -2px;
    height: 13px;
    width: 13px;
}

jQuery:

$(document).ready(function () {
    if ($.browser.msie && $.browser.version <= 7) {
        $('input[type=checkbox]').addClass('ie7');
        $('input[type=radio]').addClass('ie7');
    }
});

The styling probably needs tweaks depending on the font-size used in <label>

PS:
I use ie7js to make the css work in IE6.

if anyone is interested to see the super simple solution written in Kotlin, check the blogpost I just created. The example in the blogpost is based on creating Sectioned RecyclerView:

https://brona.blog/2020/06/sectioned-recyclerview-in-three-steps/

A better solution would be

Adding some good practices and safity to @acdcjunior's answer, to use @ instead of ./

In JavaScript

require("@/assets/images/user-img-placeholder.png")

In JSX Template

<img src="@/assets/images/user-img-placeholder.png"/>

using @ points to the src directory.

using ~ points to the project root, which makes it easier to access the node_modules and other root level resources

As indicated by the other answers, the error is to due to k = list[0:j], where your key is converted to a list. One thing you could try is reworking your code to take advantage of the split function:

# Using with ensures that the file is properly closed when you're done
with open('filename.txt', 'rb') as f:
  d = {}
  # Here we use readlines() to split the file into a list where each element is a line
  for line in f.readlines():
    # Now we split the file on `x`, since the part before the x will be
    # the key and the part after the value
    line = line.split('x')
    # Take the line parts and strip out the spaces, assigning them to the variables
    # Once you get a bit more comfortable, this works as well:
    # key, value = [x.strip() for x in line] 
    key = line[0].strip()
    value = line[1].strip()
    # Now we check if the dictionary contains the key; if so, append the new value,
    # and if not, make a new list that contains the current value
    # (For future reference, this is a great place for a defaultdict :)
    if key in d:
      d[key].append(value)
    else:
      d[key] = [value]

print d
# {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}

Note that if you are using Python 3.x, you'll have to make a minor adjustment to get it work properly. If you open the file with rb, you'll need to use line = line.split(b'x') (which makes sure you are splitting the byte with the proper type of string). You can also open the file using with open('filename.txt', 'rU') as f: (or even with open('filename.txt', 'r') as f:) and it should work fine.

Try readlink which will resolve symbolic links:

readlink -e /foo/bar/baz

This is a metadata change only: it is quick.

An observation: specify NULL or NOT NULL explicitly to avoid "accidents" if one of the SET ANSI_xx settings are different eg run in osql not SSMS for some reason

My take to describe this in a more accessible way...

In order to understand what Apache Camel is, you need to understand what Enterprise Integration Patterns are.

Let's start with what we presumably already know: The Singleton pattern, the Factory pattern, etc; They are merely ways of organizing your solution to the problem, but they are not solutions themselves. These patterns were analyzed and extracted for the rest of us by the Gang of Four, when they published their book: Design Patterns. They saved some of us tremendous effort in thinking of how to best structure our code.

Much like the Gang of Four, Gregor Hohpe and Bobby Woolf authored the book Enterprise Integration Patterns (EIP) in which they propose and document a set of new patterns and blueprints for how we could best design large component-based systems, where components can be running on the same process or in a different machine.

They basically propose that we structure our system to be message oriented -- where components communicate with each others using messages as inputs and outputs and absolutely nothing else. They show us a complete set of patterns that we may choose from and implement in our different components that will together form the whole system.

So what is Apache Camel?

Apache Camel offers you the interfaces for the EIPs, the base objects, commonly needed implementations, debugging tools, a configuration system, and many other helpers which will save you a ton of time when you want to implement your solution to follow the EIPs.

Take MVC. MVC is pretty simple in theory and we could implement it without any framework help. But good MVC frameworks provide us with the structure ready-to-use and have gone the extra mile and thought out all the other "side" things you need when you create a large MVC project and that's why we use them most of the time.

That's exactly what Apache Camel is for EIPs. It's a complete production-ready framework for people who want to implement their solution to follow the EIPs.

If Modal State is not Valid & the error cannot be seen on screen because your control is in collapsed accordion, then you can return the HttpStatusCode so that the actual error message is shown if you do F12. Also you can log this error to ELMAH error log. Below is the code

if (!ModelState.IsValid)
{
              var message = string.Join(" | ", ModelState.Values
                                            .SelectMany(v => v.Errors)
                                            .Select(e => e.ErrorMessage));

                //Log This exception to ELMAH:
                Exception exception = new Exception(message.ToString());
                Elmah.ErrorSignal.FromCurrentContext().Raise(exception);

                //Return Status Code:
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest, message);
}

But please note that this code will log all validation errors. So this should be used only when such situation arises where you cannot see the errors on screen.

print(*objects, sep=' ', end='\n', file=sys.stdout)

Note: This function is not normally available as a built-in since the name print is recognized as the print statement. To disable the statement and use the print() function, use this future statement at the top of your module:

from future import print_function

Keep in mind that @"%d" will only work on 32 bit. Once you start using NSInteger for compatibility if you ever compile for a 64 bit platform, you should use @"%ld" as your format specifier.

Interesting, thanks for the tip, I was using @"%d" with my NSIntegers!

The SDK documentation also recommends to cast NSInteger to long in this case (to match the @"%ld"), e.g.:

NSInteger i = 42;
label.text = [NSString stringWithFormat:@"%ld", (long)i];

I accidentally set the wrong file permissions. After chmod 644 phpinfo.php the info indeed showed up as expected.

Solution works very well,

public List<String> savePerson(@RequestBody Person[] personArray)  

For this signature you can pass Person array from postman like

[
{
  "empId": "10001",
  "tier": "Single",
  "someting": 6,
  "anything": 0,
  "frequency": "Quaterly"
}, {
  "empId": "10001",
  "tier": "Single",
  "someting": 6,
  "anything": 0,
  "frequency": "Quaterly"
}
]

Don't forget to add consumes tag:

@RequestMapping(value = "/getEmployeeList", method = RequestMethod.POST, consumes="application/json", produces = "application/json")
public List<Employee> getEmployeeDataList(@RequestBody Employee[] employeearray) { ... }

One useful trick in SQL is the ability use @var = function(...) to assign a value. If you have multiple records in your record set, your var is assigned multiple times with side-effects:

declare @badStrings table (item varchar(50))

INSERT INTO @badStrings(item)
SELECT '>' UNION ALL
SELECT '<' UNION ALL
SELECT '(' UNION ALL
SELECT ')' UNION ALL
SELECT '!' UNION ALL
SELECT '?' UNION ALL
SELECT '@'

declare @testString varchar(100), @newString varchar(100)

set @teststring = 'Juliet ro><0zs my s0x()rz!!?!one!@!@!@!'
set @newString = @testString

SELECT @newString = Replace(@newString, item, '') FROM @badStrings

select @newString -- returns 'Juliet ro0zs my s0xrzone'

I just had a look at the source - Protractor is waiting for Angular only in a few cases (like when element.all is invoked, or setting / getting location).

So Protractor won't wait for Angular to stabilise after every command.

Also, it looks like sometimes in my tests I had a race between Angular digest cycle and click event, so sometimes I have to do:

elm.click();
browser.driver.sleep(1000);
browser.waitForAngular();

using sleep to wait for execution to enter AngularJS context (triggered by click event).

You can use:

if (myString1.IndexOf("AbC", StringComparison.OrdinalIgnoreCase) >=0) {
    //...
}

This works with any .NET version.

you can use the zenity to displays the query output as html table.

• first implement bash script with following code:

  cat > '/tmp/sql.op'; zenity --text-info --html --filename='/tmp/sql.op';

  save it like mypager.sh

• Then export the environment variable PAGER by set full path of the script as value.

  for example:- export PAGER='/path/mypager.sh'

• Then login to the psql program then execute the command \H

• And finally execute any query,the tabled output will displayed in the zenity in html table format.

same way you did the fill in, but reverse the indexes:

>>> for j in range(columns):
...     for i in range(rows):
...        print mylist[i][j],
... 
0,0 1,0 2,0 0,1 1,1 2,1
>>> 

following won't work

echo $(awk '{awk code}' file) > file

this should work

echo "$(awk '{awk code}' file)" > file

With Mercurial you do a

$ hg grep "search for this" [file...]

There are other options that narrow down the range of revisions that are searched.

foreach only works with a single array. To step through multiple arrays, it's better to use the each() function in a while loop:

while(($code = each($codes)) && ($name = each($names))) {
    echo '<option value="' . $code['value'] . '">' . $name['value'] . '</option>';
}

each() returns information about the current key and value of the array and increments the internal pointer by one, or returns false if it has reached the end of the array. This code would not be dependent upon the two arrays having identical keys or having the same sort of elements. The loop terminates when one of the two arrays is finished.

Swift 4 solution

UIView.animate

Three simple steps:

1. Change the constraints, e.g.:

   heightAnchor.constant = 50
   

2. Tell the containing view that its layout is dirty and that the autolayout should recalculate the layout:

   self.view.setNeedsLayout()
   

3. In animation block tell the layout to recalculate the layout, which is equivalent of setting the frames directly (in this case the autolayout will set the frames):

   UIView.animate(withDuration: 0.5) {
       self.view.layoutIfNeeded()
   }
   

Complete simplest example:

heightAnchor.constant = 50
self.view.setNeedsLayout()
UIView.animate(withDuration: 0.5) {
    self.view.layoutIfNeeded()
}

Sidenote

There is an optional 0th step - before changing the constraints you might want to call self.view.layoutIfNeeded() to make sure that the starting point for the animation is from the state with old constraints applied (in case there were some other constraints changes that should not be included in animation):

otherConstraint.constant = 30
// this will make sure that otherConstraint won't be animated but will take effect immediately
self.view.layoutIfNeeded()

heightAnchor.constant = 50
self.view.setNeedsLayout()
UIView.animate(withDuration: 0.5) {
    self.view.layoutIfNeeded()
}

UIViewPropertyAnimator

Since with iOS 10 we got a new animating mechanism - UIViewPropertyAnimator, we should know that basically the same mechanism applies to it. The steps are basically the same:

heightAnchor.constant = 50
self.view.setNeedsLayout()
let animator = UIViewPropertyAnimator(duration: 0.5, timingParameters: UICubicTimingParameters(animationCurve: .linear))
animator.addAnimations {
    self.view.layoutIfNeeded()
}
animator.startAnimation()

Since animator is an encapsulation of the animation, we can keep reference to it and call it later. However, since in the animation block we just tell the autolayout to recalculate the frames, we have to change the constraints before calling startAnimation. Therefore something like this is possible:

// prepare the animator first and keep a reference to it
let animator = UIViewPropertyAnimator(duration: 0.5, timingParameters: UICubicTimingParameters(animationCurve: .linear))
animator.addAnimations {
    self.view.layoutIfNeeded()
}

// at some other point in time we change the constraints and call the animator
heightAnchor.constant = 50
self.view.setNeedsLayout()
animator.startAnimation()

The order of changing constraints and starting an animator is important - if we just change the constraints and leave our animator for some later point, the next redraw cycle can invoke autolayout recalculation and the change will not be animated.

Also, remember that a single animator is non-reusable - once you run it, you cannot "rerun" it. So I guess there is not really a good reason to keep the animator around, unless we use it for controlling an interactive animation.

There are three states of button

• Normal : You can select like this button
• Hover : You can select like this button:hover
• Pressed/Clicked : You can select like this button:active

Normal:

.button
 {
     //your css
 }

Active

 .button:active
{
        //your css
}

Hover

 .button:hover
{
        //your css
}

SNIPPET:

Use :active to style the active state of button.

button:active{_x000D_
   background-color:red;_x000D_
}

<button>Click Me</button>

It is not possible to redirect a POST somewhere else. When you have POSTED the request, the browser will get a response from the server and then the POST is done. Everything after that is a new request. When you specify a location header in there the browser will always use the GET method to fetch the next page.

You could use some Ajax to submit the form in background. That way your form values stay intact. If the server accepts, you can still redirect to some other page. If the server does not accept, then you can display an error message, let the user correct the input and send it again.

If you have only 1 object like the one you asked, the following will work.

var x = [{'a':'b'}];
var b= JSON.stringify(x);
var c = b.substring(1,b.length-1);
JSON.parse(c); 

There is 2 ways to do it in angularjs..

1) By directly redirecting to your service call..

<a href="some/path/to/the/file">clickme</a>

2) By submitting hidden form.

$scope.saveAsPDF = function() {
    var form = document.createElement("form");
    form.setAttribute("action", "some/path/to/the/file");
    form.setAttribute("method", "get");
    form.setAttribute("target", "_blank");

    var hiddenEle1 = document.createElement("input");
    hiddenEle1.setAttribute("type", "hidden");
    hiddenEle1.setAttribute("name", "some");
    hiddenEle1.setAttribute("value", value);

    form.append(hiddenEle1 );

    form.submit();

}

use the hidden element when you have to post some element

<button ng-click="saveAsPDF()">Save As PDF</button>

Strictly speaking, private methods are accessible outside their class, just not easily accessible. Nothing in Python is truly private; internally, the names of private methods and attributes are mangled and unmangled on the fly to make them seem inaccessible by their given names. You can access the __parse method of the MP3FileInfo class by the name _MP3FileInfo__parse. Acknowledge that this is interesting, then promise to never, ever do it in real code. Private methods are private for a reason, but like many other things in Python, their privateness is ultimately a matter of convention, not force.

A temp table can be created in the caller and then populated from the called SP.

  create table #GetValuesOutputTable(
     ...   
  );

  exec GetValues; -- populates #GetValuesOutputTable

  select * from #GetValuesOutputTable;

Some advantages of this approach over the "insert exec" is that it can be nested and that it can be used as input or output.

Some disadvantages are that the "argument" is not public, the table creation exists within each caller, and that the name of the table could collide with other temp objects. It helps when the temp table name closely matches the SP name and follows some convention.

Taking it a bit farther, for output only temp tables, the insert-exec approach and the temp table approach can be supported simultaneously by the called SP. This doesn't help too much for chaining SP's because the table still need to be defined in the caller but can help to simplify testing from the cmd line or when calling externally.

  -- The "called" SP
  declare
      @returnAsSelect bit = 0;

  if object_id('tempdb..#GetValuesOutputTable') is null
  begin
      set @returnAsSelect = 1;
      create table #GetValuesOutputTable(
         ...   
      );
  end

  -- populate the table

  if @returnAsSelect = 1
      select * from #GetValuesOutputTable;

Example solution for adding the library to your PYTHONPATH.

1. Add the following line into your ~/.bashrc or just run it directly:

   export PYTHONPATH="$PYTHONPATH:$HOME/.python"
   

2. Then link your required library into your ~/.python folder, e.g.

   ln -s /home/user/work/project/foo ~/.python/
   

I had the same problem just now and it was solved by simply reinstalling to the latest version of VirtualBox.

For those on Mac OS High Sierra - the installation might fail at first but you need to go to System Preferences > Security & Policy and click on the "Allow" button to allow Oracle installing the software.

Using the @WebFilter annotation, it can be done as follows:

@WebFilter(urlPatterns = {"/*" })
public class AuthenticationFilter implements Filter{

    private static Logger logger = Logger.getLogger(AuthenticationFilter.class);

    @Override
    public void destroy() {
        // TODO Auto-generated method stub

    }

    @Override
    public void doFilter(ServletRequest arg0, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

         logger.info("checking client id in filter");
        HttpServletRequest request = (HttpServletRequest) arg0;
        String clientId = request.getHeader("clientId");
        if (StringUtils.isNotEmpty(clientId)) {
            chain.doFilter(request, response);
        } else {
            logger.error("client id missing.");
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {
        // TODO Auto-generated method stub

    }

}

You could convert it to a string instead of printing the list directly:

print(", ".join(LIST))

If the elements in the list aren't strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don't), like so:

LIST = [1, "foo", 3.5, { "hello": "bye" }]
print( ", ".join( repr(e) for e in LIST ) )

Which gives the output:

1, 'foo', 3.5, {'hello': 'bye'}

This error could also appear if you are having network latency or internet or local network problems. Bridged connections that have a failing counterpart may be the culprit as well.

alternatively you can perform a fast export without using Office dll, as Excel can parse csv files without problems.

                    aVisibleData.Add(p_oGrid.Columns(iAuxRow).Name)
                    sText.Append(p_oGrid.Columns(iAuxRow).HeaderText.ToUpper)
                    sText.Append(";")
                End If
            Next

If you want to append this css file to header you can do it using mounted() function of the vue file. See the example.
Note: Assume you can access the css file as http://www.yoursite/assets/styles/vendor.css in the browser.

mounted() {
        let style = document.createElement('link');
        style.type = "text/css";
        style.rel = "stylesheet";

I occasionally have the same issue but mostly after macOS upgrades. Shutting down and migrating to the new version usually fixes it for me(make changes according to your version). So first upgrade your postgresql

brew services stop postgresql@12
brew services start postgresql@12
brew postgresql-upgrade-database

This is mostly a temporary fix but since I couldn't find a better solution this works for me.

Update: If the issue says that another postmaster is running then try removing it from that location(your postmaster.pid location will be displayed to you)

rm /usr/local/var/postgres/postmaster.pid

Personally I dislike hanging open blocks, so I'd format it as:

logger.info(
    'Skipping {0} because its thumbnail was already in our system as {1}.'
    .format(line[indexes['url']], video.title)
)

In general I wouldn't bother struggle too hard to make code fit exactly within a 80-column line. It's worth keeping line length down to reasonable levels, but the hard 80 limit is a thing of the past.

There are multiple options to implement SSO for a .NET application.

Check out the following tutorials online:

Basics of Single Sign on, July 2012

http://www.codeproject.com/Articles/429166/Basics-of-Single-Sign-on-SSO

GaryMcAllisterOnline: ASP.NET MVC 4, ADFS 2.0 and 3rd party STS integration (IdentityServer2), Jan 2013

http://garymcallisteronline.blogspot.com/2013/01/aspnet-mvc-4-adfs-20-and-3rd-party-sts.html

The first one uses ASP.NET Web Forms, while the second one uses ASP.NET MVC4.

If your requirements allow you to use a third-party solution, also consider OpenID. There's an open source library called DotNetOpenAuth.

For further information, read MSDN blog post Integrate OpenAuth/OpenID with your existing ASP.NET application using Universal Providers.

Hope this helps!

Also, you can call into Objective-C runtime to call the method.

$objPHPExcel->getActiveSheet()->getStyle("A1:".$objPHPExcel->getActiveSheet()->getHighestDataColumn()."1")->getFont()->setBold(true);

I found this to be a working solution, you can replace the two instances of 1 with the row number. The HighestDataColumn function returns for example C or Z, it gives you the last/highest column that's in the sheet containing any data. There is also getHighestColumn(), that one would include cells that are empty but have styling or are part of other functionality.

I recently came across Python 3 interpreter at CompileOnline.

Here is the syntax:

  set terminal pdf {monochrome|color|colour}
                   {{no}enhanced}
                   {fname "<font>"} {fsize <fontsize>}
                   {font "<fontname>{,<fontsize>}"}
                   {linewidth <lw>} {rounded|butt}
                   {solid|dashed} {dl <dashlength>}}
                   {size <XX>{unit},<YY>{unit}}

and an example:

set terminal pdfcairo monochrome enhanced font "Times-New-Roman,12" dashed

To unzip all files in a directory just type this cmd in terminal:

unzip '*.zip'

"start" is a name of a script, in npm you run scripts like this npm run scriptName, npm start is also a short for npm run start

As for "react-scripts" this is a script related specifically to create-react-app

promiseA(pram).then(
     result => { 
     //make sure promiseA function allready success and response
     //do something here
}).catch(err => console.log(err)) => {
     // handle error with try catch
}

Chrome is a Chromium-based browser and Chromium-based browsers only allow maximum 6 open socket connections at a time, when the 7th connection starts up it will just sit idle and wait for one of the 6 which are running to stop and then it will start running. Hence the error code ‘waiting for available sockets’, the 7th one will wait for one of those 6 sockets to become available and then it will start running.

You can either

• 1. Clear browser cache & cookies (https://geekdroids.com/waiting-for-available-socket/#1_Clear_browser_cache_cookies)
• 2. Flush socket pools (https://geekdroids.com/waiting-for-available-socket/#2_Flush_socket_pools)
• 3. Flush DNS (https://geekdroids.com/waiting-for-available-socket/#3_Flush_DNS)

You can filter all characters from the string that are not printable using string.printable, like this:

>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'

string.printable on my machine contains:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c

EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:

''.join(filter(lambda x: x in printable, s))

Direct to remove the '\n' from the fgets output if every line has '\n'

line[strlen(line) - 1] = '\0';

Otherwise:

void remove_newline_ch(char *line)
{
    int new_line = strlen(line) -1;
    if (line[new_line] == '\n')
        line[new_line] = '\0';
}

Here's pure javascript example of handling classes during scrolling.

You'd probably want to throttle handling scroll events, more so as handler logic gets more complex, in that case throttle from lodash lib comes in handy.

And if you're doing spa, keep in mind that you need to clear event listeners with removeEventListener once they're not needed (eg during onDestroy lifecycle hook of your component, like destroyed() for Vue, or maybe return function of useEffect hook for React).

const navbar = document.getElementById('navbar')_x000D_
_x000D_
// OnScroll event handler_x000D_
const onScroll = () => {_x000D_
_x000D_
  // Get scroll value_x000D_
  const scroll = document.documentElement.scrollTop_x000D_
_x000D_
  // If scroll value is more than 0 - add class_x000D_
  if (scroll > 0) {_x000D_
    navbar.classList.add("scrolled");_x000D_
  } else {_x000D_
    navbar.classList.remove("scrolled")_x000D_
  }_x000D_
}_x000D_
_x000D_
// Optional - throttling onScroll handler at 100ms with lodash_x000D_
const throttledOnScroll = _.throttle(onScroll, 100, {})_x000D_
_x000D_
// Use either onScroll or throttledOnScroll_x000D_
window.addEventListener('scroll', onScroll)

#navbar {_x000D_
  position: fixed;_x000D_
  top: 0;_x000D_

Here is an example how to parse JSON response and even how to send a request with a bean in JSON form:

  @Autowired
  protected MockMvc mvc;

  private static final ObjectMapper MAPPER = new ObjectMapper()
    .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
    .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
    .registerModule(new JavaTimeModule());

  public static String requestBody(Object request) {
    try {
      return MAPPER.writeValueAsString(request);
    } catch (JsonProcessingException e) {
      throw new RuntimeException(e);
    }
  }

  public static <T> T parseResponse(MvcResult result, Class<T> responseClass) {
    try {
      String contentAsString = result.getResponse().getContentAsString();
      return MAPPER.readValue(contentAsString, responseClass);
    } catch (IOException e) {
      throw new RuntimeException(e);
    }
  }

  @Test
  public void testUpdate() {
    Book book = new Book();
    book.setTitle("1984");
    book.setAuthor("Orwell");
    MvcResult requestResult = mvc.perform(post("http://example.com/book/")
      .contentType(MediaType.APPLICATION_JSON)
      .content(requestBody(book)))
      .andExpect(status().isOk())
      .andReturn();
    UpdateBookResponse updateBookResponse = parseResponse(requestResult, UpdateBookResponse.class);
    assertEquals("1984", updateBookResponse.getTitle());
    assertEquals("Orwell", updateBookResponse.getAuthor());
  }

As you can see here the Book is a request DTO and the UpdateBookResponse is a response object parsed from JSON. You may want to change the Jackson's ObjectMapper configuration.

There's an error in your code. You're using a mix of full syntax and shorthand notation on the background-image property.This is causing the no-repeat to be ignored, since it's not a valid value for the background-image property.

body{   
    background-position:center;
    background-image:url(../images/images2.jpg) no-repeat;
}

Should become one of the following:

body{
    background:url(../images/images2.jpg) center center no-repeat;
}

or

body
{
    background-image: url(path-to-file/img.jpg);
    background-repeat:no-repeat;
    background-position: center center;
}

EDIT: For your image 'scaling' issue, you might want to look at this question's answer.

1. If you want to integrate Retrofit (all steps defined here):

Goto my blog : retrofit with kotlin

2. Please use android-async-http library.

the link below explains everything step by step.

http://loopj.com/android-async-http/

Here are sample apps:

1. http://www.techrepublic.com/blog/software-engineer/calling-restful-services-from-your-android-app/

2. http://blog.strikeiron.com/bid/73189/Integrate-a-REST-API-into-Android-Application-in-less-than-15-minutes

Create a class :

public class HttpUtils {
  private static final String BASE_URL = "http://api.twitter.com/1/";
 
  private static AsyncHttpClient client = new AsyncHttpClient();

  public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(getAbsoluteUrl(url), params, responseHandler);
  }

  public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(getAbsoluteUrl(url), params, responseHandler);
  }
      
  public static void getByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(url, params, responseHandler);
  }

  public static void postByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(url, params, responseHandler);
  }

  private static String getAbsoluteUrl(String relativeUrl) {
      return BASE_URL + relativeUrl;
  }
}

Call Method :

    RequestParams rp = new RequestParams();
    rp.add("username", "aaa"); rp.add("password", "aaa@123");
                    
    HttpUtils.post(AppConstant.URL_FEED, rp, new JsonHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
            // If the response is JSONObject instead of expected JSONArray
            Log.d("asd", "---------------- this is response : " + response);
            try {
                JSONObject serverResp = new JSONObject(response.toString());                                                
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }                   
        }
            
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
            // Pull out the first event on the public timeline
                    
        }
    });

Please grant internet permission in your manifest file.

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

you can add compile 'com.loopj.android:android-async-http:1.4.9' for Header[] and compile 'org.json:json:20160212' for JSONObject in build.gradle file if required.

For .NET server can configure this in web.config as shown below

 <system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="your_clientside_websiteurl" />
     </customHeaders>
   </httpProtocol>
 </system.webServer>

For instance lets say, if the server domain is http://live.makemypublication.com and client is http://www.makemypublication.com then configure in server's web.config as below

 <system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="http://www.makemypublication.com" />
     </customHeaders>
  </httpProtocol>
 </system.webServer>

A little cheat sheet on module queries.

To check all existing versions: e.g. go list -m -versions github.com/gorilla/mux

1. Specific version @v1.2.8
2. Specific commit @c783230
3. Specific branch @master
4. Version prefix @v2
5. Comparison @>=2.1.5
6. Latest @latest

E.g. go get github.com/gorilla/[email protected]

I'm starting in the webdesign universe and i used DIVs inside LIs with no problem with the semantics. I think that DIVs aren't allowed on lists, that means you can't put a DIV inside an UL, but it has no problem inserting it on a LI (because LI are just list items haha) The problem that i have been encountering is that sometimes the DIV behaves somewhat different from usual, but nothing that our good CSS can't handle haha. Anyway, sorry for my bad english and if my response wasn't helpful haha good luck!

    // here, you have your sum
});?????????

An easy way to serialize Enum is using @JsonFormat annotation. @JsonFormat can configure the serialization of a Enum in three ways.

@JsonFormat.Shape.STRING
public Enum OrderType {...}

uses OrderType::name as the serialization method. Serialization of OrderType.TypeA is “TYPEA”

@JsonFormat.Shape.NUMBER
Public Enum OrderTYpe{...}

uses OrderType::ordinal as the serialization method. Serialization of OrderType.TypeA is 1

@JsonFormat.Shape.OBJECT
Public Enum OrderType{...}

treats OrderType as a POJO. Serialization of OrderType.TypeA is {"id":1,"name":"Type A"}

JsonFormat.Shape.OBJECT is what you need in your case.

A little more complicated way is your solution, specifying a serializer for the Enum.

Check out this reference: https://fasterxml.github.io/jackson-annotations/javadoc/2.2.0/com/fasterxml/jackson/annotation/JsonFormat.html

Neither of these does anything useful. Use isalpha() or isdigit() from the standard library. They're in <ctype.h>.

For Single Index :

 df.index.rename('new_name')

For Multi Index :

 df.index.rename(['new_name','new_name2'])

WE can also use this in latest pandas :

rename_axis

Internet explorer has a reset to factory button and luckily so does chrome! try the link below and let us know. the other option is to stop chrome and delete the c:\users\%username%\appdata\local\google folder entirely then reinstall chrome but this will loose all you local settings and data.

Make use of Arrow functions it improves the readability of code. No need to return anything in API.fetchComments, Api call is asynchronous when the request is completed then will get the response, there you have to just dispatch type and data.

Below code does the same job by making use of Arrow functions.

export const bindComments = postId => {
  return dispatch => {
    API.fetchComments(postId).then(comments => {
      dispatch({
        type: BIND_COMMENTS,
        comments,
        postId
      });
    });
  };
};

if you are using width and height, you should try margin-right: 45%;... it is 100% working for me.. so i can take it to anywhere with percentage!

If you're interested in preserving aspect ratios and doing so in pure CSS (given the aspect ratio) you can do something like below. The key is the padding-bottom on the ::content element that sizes the container element. This is sized relative to its parent's width, which is 100% by default. The ratio specified here has to match up with the ratio of the sizes on the canvas element.

I found below SSH commands are robust for export/import huge MySql databases, at least I'm using them for years. Never rely on backups generated via control panels like cPanel WHM, CWP, OVIPanel, etc they may trouble you especially when you're switching between control panels, trust SSH always.

$ mysqldump -u root -p example_database| gzip > example_database.sql.gz 

[IMPORT]

$ gunzip < example_database.sql.gz | mysql -u root -p example_database 

In Java, this return value fails with jQuery Ajax GET:

return Response.status(200).entity(pojoObj).build();

But this works:

ResponseBuilder rb = Response.status(200).entity(pojoObj);
return rb.header("Access-Control-Allow-Origin", "*").build();

----

Full class:

@Path("/password")
public class PasswordStorage {
    @GET
    @Produces({ MediaType.APPLICATION_JSON })
    public Response getRole() {
        Contact pojoObj= new Contact();
        pojoObj.setRole("manager");

        ResponseBuilder rb = Response.status(200).entity(pojoObj);
        return rb.header("Access-Control-Allow-Origin", "*").build();

        //Fails jQuery: return Response.status(200).entity(pojoObj).build();
    }
}

@Esteban Küber is absolutely right.

Maybe one additional hint for bloody beginners like me. If you speciify the variables with %s, you have to follow this principle for EVERY input value, which means for the SET-variables as well as for the WHERE-variables.

Otherwise, you will have to face a termination message like 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s WHERE'

The character set is part of the locale, which is determined by the value of NLS_LANG. As the documentation makes clear this is an operating system variable:

NLS_LANG is set as an environment variable on UNIX platforms. NLS_LANG is set in the registry on Windows platforms.

Now we can use ALTER SESSION to change the values for a couple of locale elements, NLS_LANGUAGE and NLS_TERRITORY. But not, alas, the character set. The reason for this discrepancy is - I think - that the language and territory simply effect how Oracle interprets the stored data, e.g. whether to display a comma or a period when displaying a large number. Wheareas the character set is concerned with how the client application renders the displayed data. This information is picked up by the client application at startup time, and cannot be changed from within.

I got this error because such DLL (and many others) were missing in bin folder when I pubished the web application. It seemed like a bug in Visual Studio publish function. Cleaning, recompiling and publishing it again, made such DLLs to be published correctly.

You could use sed:

ls * | sed -e 'p;s@_.*_@_@g' | xargs -n2 mv

result:

prefix_567.png prefix_efg.png

*to do a dry-run first, replace mv at the end with echo

Explanation:

• e: optional for only 1 sed command.
• p: to print the input to sed, in this case it will be the original file name before any renaming
• @: is a replacement of / character to make sed more readable. That is, instead of using sed s/search/replace/g, use s@search@replace@g
• _.* : the underscore is an escape character to refer to the actual '.' character zero or more times (as opposed to ANY character in regex)
• -n2: indicates that there are 2 outputs that need to be passed on to mv as parameters. for each input from ls, this sed command will generate 2 output, which will then supplied to mv.

I found this question while Googling. Note that if you just want to make use of the URI's content via something like a string, consider using Apache's IOUtils.toString() method.

For example, a sample line of code could be:

String pageContent = IOUtils.toString("http://maps.google.at/maps?saddr=4714&daddr=Marchtrenk&hl=de", Charset.UTF_8);

Create the user with a password :

http://www.postgresql.org/docs/current/static/sql-createuser.html

CREATE USER name [ [ WITH ] option [ ... ] ]

where option can be:

      SUPERUSER | NOSUPERUSER
    | CREATEDB | NOCREATEDB
    | CREATEROLE | NOCREATEROLE
    | CREATEUSER | NOCREATEUSER
    | INHERIT | NOINHERIT
    | LOGIN | NOLOGIN
    | REPLICATION | NOREPLICATION
    | CONNECTION LIMIT connlimit
    | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
    | VALID UNTIL 'timestamp'
    | IN ROLE role_name [, ...]
    | IN GROUP role_name [, ...]
    | ROLE role_name [, ...]
    | ADMIN role_name [, ...]
    | USER role_name [, ...]
    | SYSID uid

Then grant the user rights on a specific database :

http://www.postgresql.org/docs/current/static/sql-grant.html

Example :

grant all privileges on database db_name to someuser;

i know this is an old post, but i wanted to provide a JQuery plugin version and my code.

// Find the first occurrence of object in list, Similar to $.grep, but stops searching 
function findFirst(a,b){
var i; for (i = 0; i < a.length; ++i) { if (b(a[i], i)) return a[i]; } return undefined;
}

usage:

var product = $.findFirst(arrProducts, function(p) { return p.id == 10 });

When you write

df['Date'] = pd.to_datetime(df['Date'], errors='coerce')
df['Date'] = df['Date'].dt.strftime('%m/%d')

It can fixed

var dict = []

Add Object into Dictionary

dict.push(
     { key: "One",value: false},
     { key: "Two",value: false},
     { key: "Three",value: false});

Output : 
   [0: {key: "One", value: false}
    1: {key: "Two", value: false}
    2: {key: "Three", value: false}]

Update Object from Dictionary

Object.keys(dict).map((index) => {        
  if (index == 1){
    dict[index].value = true
  }
});

Output : 
   [0: {key: "One", value: false},
    1: {key: "Two", value: true},
    2: {key: "Three", value: false}]

Delete Object from Dictionary

Object.keys(dict).map((index) => {              
      if (index == 2){
        dict.splice(index)
      }
    });

Output : 
    [0: {key: "One", value: false},
     1: {key: "Two", value: true}]

If you want to create a li element for each input/name, then you have to create it, with document.createElement ^[MDN].

Give the list the ID:

<ol id="demo"></ol>

and get a reference to it:

var list = document.getElementById('demo');

In your event handler, create a new list element with the input value as content and append to the list with Node.appendChild ^[MDN]:

var firstname = document.getElementById('firstname').value;
var entry = document.createElement('li');
entry.appendChild(document.createTextNode(firstname));
list.appendChild(entry);

DEMO

As it is written in the documentation you have to change the cell type to a markdown.

Here is the example:

function MethodName($scope)
{
    $scope.date = new Date();
}

You can change the format in view here we have a code

<div ng-app ng-controller="MethodName">
    My current date is {{date | date:'yyyy-MM-dd'}} . 
</div>

I hope it helps.

You almost did it. You were tricked by the fact that abs(imagem-255) will give a wrong result since your dtype is an unsigned integer. You have to do (255-imagem) in order to keep the integers unsigned:

def inverte(imagem, name):
    imagem = (255-imagem)
    cv2.imwrite(name, imagem)

You can also invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

double click the button and add write // this.close();

  private void buttonClick(object sender, EventArgs e)
{
    this.Close();
}

I was also getting the same issue of breaking constraints in the log, for a viewCircle in the xib. I almost tried everything listed above and nothing was working for me. Then I tried to change the priority of the Height constraint which was breaking in the log(confirmed by adding an identifiers for the constraints on the xib)enter image description here

To display a dialog or a toaster in a thread, the most concise way is to use the Activity object.

For example:

new Thread(new Runnable() {
    @Override
    public void run() {
        myActivity.runOnUiThread(new Runnable() {
            public void run() {
                myActivity.this.processingWaitDialog = new ProgressDialog(myActivity.this.getContext());
                myActivity.this.processingWaitDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
                myActivity.this.processingWaitDialog.setMessage("abc");
                myActivity.this.processingWaitDialog.setIndeterminate(true);
                myActivity.this.processingWaitDialog.show();
            }
        });
        expenseClassify.serverPost(
                new AsyncOperationCallback() {
                    public void operationCompleted(Object sender) {
                        myActivity.runOnUiThread(new Runnable() {
                            public void run() {
                                if (myActivity.this.processingWaitDialog != null 
                                        && myActivity.this.processingWaitDialog.isShowing()) {
                                    myActivity.this.processingWaitDialog.dismiss();
                                    myActivity.this.processingWaitDialog = null;
                                }
                            }
                        }); // .runOnUiThread(new Runnable()
...

Yes, reload the css tag. And remember to make the new url unique (usually by appending a random query parameter). I have code to do this but not with me right now. Will edit later...

edit: too late... harto and nickf beat me to it ;-)

You could use a javascript snippit

$(function()
{
    // Enable drop menu clicks
    $(".nav li > a").off();
});

That will unbind the click event preventing url changing.

Another way which could make sense for the given situation is

BigDecimal newBD = oldBD.setScale(2);

I just say this because in some cases when it comes to money going beyond 2 decimal places does not make sense. Taking this a step further, this could lead to

String displayString = oldBD.setScale(2).toPlainString();

but I merely wanted to highlight the setScale method (which can also take a second rounding mode argument to control how that last decimal place is handled. In some situations, Java forces you to specify this rounding method).

You could use the n-th child selector.

to target the nth element you could then use:

td:nth-child(n) {  
  /* your stuff here */
}

(where n starts at 1)

In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:

1. validating the data POSTed

2. make sure your API is sending the Content-Type header to tell the client to expect a JSON response:

   header('Content-Type: application/json');
   echo json_encode($response);
   

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.

If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController with an add() action/method.

There are a few starting point projects for RESTful APIs on GitHub that are worth a look.

Bootstrap tabs are not responsive out of the box. Responsive, IMO, is a style change, changing functions is Adaptive. There are a few plugins to turn the Bootstrap 3 tabs into a Collapse component. The best and most updated one is : https://github.com/flatlogic/bootstrap-tabcollapse.

Here's one way of implementing it:

DEMO: http://jsbin.com/zibani/1/

EDIT: http://jsbin.com/zibani/1/edit

This turns the content into a collapse component:

Dependencies:

1. Bootstrap 3.2 css or higher but still in the 3 series
2. Bootstrap 3.2 jQuery or higher but still in the 3 series
3. Compatible version of bootstrap-tabcollapse.js

HTML -- same as question with class name addition:

       <ul class="nav nav-tabs content-tabs" id="maincontent" role="tablist">

jQuery:

$(document).ready(function() {

    // DEPENDENCY: https://github.com/flatlogic/bootstrap-tabcollapse
    $('.content-tabs').tabCollapse();

    // initialize tab function
    $('.nav-tabs a').click(function(e) {
        e.preventDefault();
        $(this).tab('show');
    });

});

CSS -- optional for fat fingers and active states:

.panel-heading {
    padding: 0
}
.panel-heading a {
    display: block;
    padding: 20px 10px;
}
.panel-heading a.collapsed {
    background: #fff
}
.panel-heading a {
    background: #f7f7f7;
    border-radius: 5px;
}
.panel-heading a:after {
    content: '-'
}
.panel-heading a.collapsed:after {
    content: '+'
}
.nav.nav-tabs li a,
.nav.nav-tabs li.active > a:hover,
.nav.nav-tabs li.active > a:active,
.nav.nav-tabs li.active > a:focus {
    border-bottom-width: 0px;
    outline: none;
}
.nav.nav-tabs li a {
    padding-top: 20px;
    padding-bottom: 20px;
}
.tab-pane {
    background: #fff;
    padding: 10px;
    border: 1px solid #ddd;
    margin-top: -1px;
}

I've read all the previously posted answers, and they require a lot of extra work. The quick and simple solution I have found is as follows:

1) Un-group the date field in the pivot table. 2) Go to the Pivot Field List UI. 3) Re-arrange your fields so that the Date field is listed FIRST in the ROWS section. 4) Under the Design menu, select Report Layout / Show in Tabular Form.

By default, Excel sorts by the first field in a pivot table. You may not want the Date field to be first, but it's a compromise that will save you time and much work.

I couldn't ever find an answer that really satisfied the original question, so I put together a simple free service (PostMail) that allows you to make a standard HTTP POST request to send an email. When you sign up, it provides you with code that you can copy & paste into your website. In this case, you can simply use a form post:

HTML:

<form action="https://postmail.invotes.com/send"
    method="post" id="email_form">

    <input type="text" name="subject" placeholder="Subject" />
    <textarea name="text" placeholder="Message"></textarea>
    <!-- replace value with your access token -->
    <input type="hidden" name="access_token" value="{your access token}" />

    <input type="hidden" name="success_url"
      value=".?message=Email+Successfully+Sent%21&isError=0" />
    <input type="hidden" name="error_url"
      value=".?message=Email+could+not+be+sent.&isError=1" />

    <input id="submit_form" type="submit" value="Send" />
</form>

Again, in full disclosure, I created this service because I could not find a suitable answer.

If you want to get all new things in the past 5 minutes you would have to do some calculations, but its not hard...

First create an index on the property you want to match on (include sort direction -1 for descending and 1 for ascending)

db.things.createIndex({ createdAt: -1 }) // descending order on .createdAt

Then query for documents created in the last 5 minutes (60 seconds * 5 minutes)....because javascript's .getTime() returns milliseconds you need to mulitply by 1000 before you use it as input to the new Date() constructor.

db.things.find({
        createdAt: {
            $gte: new Date(new Date().getTime()-60*5*1000).toISOString()
         }
     })
     .count()

Explanation for new Date(new Date().getTime()-60*5*1000).toISOString() is as follows:

First we calculate "5 minutes ago":

1. new Date().getTime() gives us current time in milliseconds
2. We want to subtract 5 minutes (in ms) from that: 5*60*1000 -- I just multiply by 60 seconds so its easy to change. I can just change 5 to 120 if I want 2 hours (120 minutes).
3. new Date().getTime()-60*5*1000 gives us 1484383878676 (5 minutes ago in ms)

Now we need to feed that into a new Date() constructor to get the ISO string format required by MongoDB timestamps.

1. { $gte: new Date(resultFromAbove).toISOString() } (mongodb .find() query)
2. Since we can't have variables we do it all in one shot: new Date(new Date().getTime()-60*5*1000)
3. ...then convert to ISO string: .toISOString()
4. new Date(new Date().getTime()-60*5*1000).toISOString() gives us 2017-01-14T08:53:17.586Z

Of course this is a little easier with variables if you're using the node-mongodb-native driver, but this works in the mongo shell which is what I usually use to check things.

Do configure --help and see what other options are available.

It is very common to provide different options to override different locations. By standard, --prefix overrides all of them, so you need to override config location after specifying the prefix. This course of actions usually works for every automake-based project.

The worse case scenario is when you need to modify the configure script, or even worse, generated makefiles and config.h headers. But yeah, for Xfce you can try something like this:

./configure --prefix=/home/me/somefolder/mybuild/output/target --sysconfdir=/etc 

I believe that should do it.

Swift 2.0

    let dateNow = NSDate()
    let calendar = NSCalendar.currentCalendar()
    let hour = calendar.component(NSCalendarUnit.Hour, fromDate: dateNow)
    let minute = calendar.component(NSCalendarUnit.Minute, fromDate: dateNow)
    print(String(hour))
    print(String(minute))

Please do take note of the cast to String in the print statement, you can easily assign that value to variables, like this:

var hoursString = String(hour)
var minutesString = String(minute)

Then you can concatenate values like this:

var compoundString = "\(hour):\(minute)"
print(compoundString)

There is nothing wrong with syntax of

$('#part' + number).html(text);

jQuery accepts a String (usually a CSS Selector) or a DOM Node as parameter to create a jQuery Object.

In your case you should pass a String to $() that is

$(<a string>)

Make sure you have access to the variables number and text.

To test do:

function(){
    alert(number + ":" + text);//or use console.log(number + ":" + text)
    $('#part' + number).html(text);
}); 

If you see you dont have access, pass them as parameters to the function, you have to include the uual parameters for $.get and pass the custom parameters after them.

I set the max width for my video to be 100%. On phones the video automatically fits the width of the screen. Since the embedded video is only 560px wide, I just added a 10% left-margin to the iframe, and put a "0" back in for the margin for the mobile CSS (to allow the full width view). I did't want to bother putting a div around every video...

Desktop CSS:

iframe {_x000D_
  margin-left: 10%;_x000D_
 }

Mobile CSS:

iframe {_x000D_
  margin-left: 0;_x000D_
 }

Worked perfect for my blog (Botanical Amy).

This question is a bit old now (don't know why I keep hitting old questions today) but I was thinking about BOOST_FUSION_ADAPT_STRUCT which introduces compile-time reflection.

It is up to you to map this to run-time reflection of course, and it won't be too easy, but it is possible in this direction, while it would not be in the reverse :)

I really think a macro to encapsulate the BOOST_FUSION_ADAPT_STRUCT one could generate the necessary methods to get the runtime behavior.

Using regular expressions to check for nested patterns is very easy.

'/(\((?>[^()]+|(?1))*\))/'

You can try this way -

ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
    duration = 2000
    start()
}

Note - view is your view where you want animation.

Since an example of Apache FastDateFormat(click for the documentations of versions:2.6and3.5) is missing here, I am adding one for those who may need it. The key here is the pattern ZZ(2 capital Zs).

import java.text.ParseException
import java.util.Date;
import org.apache.commons.lang3.time.FastDateFormat;
public class DateFormatTest throws ParseException {
    public static void main(String[] args) {
        String stringDateFormat = "yyyy-MM-dd'T'HH:mm:ssZZ";
        FastDateFormat fastDateFormat = FastDateFormat.getInstance(stringDateFormat);
        System.out.println("Date formatted into String:");
        System.out.println(fastDateFormat.format(new Date()));
        String stringFormattedDate = "2016-11-22T14:30:14+05:30";
        System.out.println("String parsed into Date:");
        System.out.println(fastDateFormat.parse(stringFormattedDate));
    }
}

Here is the output of the code:

Date formatted into String:
2016-11-22T14:52:17+05:30
String parsed into Date:
Tue Nov 22 14:30:14 IST 2016

Note: The above code is of Apache Commons' lang3. The class org.apache.commons.lang.time.FastDateFormat does not support parsing, and it supports only formatting. For example, the output of the following code:

import java.text.ParseException;
import java.util.Date;
import org.apache.commons.lang.time.FastDateFormat;
public class DateFormatTest {
    public static void main(String[] args) throws ParseException {
        String stringDateFormat = "yyyy-MM-dd'T'HH:mm:ssZZ";
        FastDateFormat fastDateFormat = FastDateFormat.getInstance(stringDateFormat);
        System.out.println("Date formatted into String:");
        System.out.println(fastDateFormat.format(new Date()));
        String stringFormattedDate = "2016-11-22T14:30:14+05:30";
        System.out.println("String parsed into Date:");
        System.out.println(fastDateFormat.parseObject(stringFormattedDate));
    }
}

will be this:

Date formatted into String:
2016-11-22T14:55:56+05:30
String parsed into Date:
Exception in thread "main" java.text.ParseException: Format.parseObject(String) failed
    at java.text.Format.parseObject(Format.java:228)
    at DateFormatTest.main(DateFormatTest.java:12)

Here is the difference:

Imperative:

• Start
• Turn on your shoes size 9 1/2.
• Make room in your pocket to keep an array[7] of keys.
• Put the keys in the room for the keys in the pocket.
• Enter garage.
• Open garage.
• Enter Car.

... and so on and on ...

• Put the milk in the refrigerator.
• Stop.

Declarative, whereof functional is a subcategory:

• Milk is a healthy drink, unless you have problems digesting lactose.
• Usually, one stores milk in a refrigerator.
• A refrigerator is a box that keeps the things in it cool.
• A store is a place where items are sold.
• By "selling" we mean the exchange of things for money.
• Also, the exchange of money for things is called "buying".

... and so on and on ...

• Make sure we have milk in the refrigerator (when we need it - for lazy functional languages).

Summary: In imperative languages you tell the computer how to change bits, bytes and words in it's memory and in what order. In functional ones, we tell the computer what things, actions etc. are. For example, we say that the factorial of 0 is 1, and the factorial of every other natural number is the product of that number and the factorial of its predecessor. We don't say: To compute the factorial of n, reserve a memory region and store 1 there, then multiply the number in that memory region with the numbers 2 to n and store the result at the same place, and at the end, the memory region will contain the factorial.

I think you can use [UIScreen mainScreen].bounds.size.height and calculate step for your objects. when you calculate step you can set coordinates for two resolutions.

Or you can get height like above and if(iphone5) then... else if(iphone4) then... else if(ipad). Something like this.

If you use storyboards then you have to create new for new iPhone i think.

It dipends on which distribution you are in general but... You have to install the php-curl module and then enable it on php.ini like you did in windows. Once you are done remember to restart apache demon!

This is an addendum to the accepted answer by AndreyT, with Nyan's comment on mismatched array sizes. I disagree with their automatic setting of the fifth element to zero. It should likely be 5 --the number after 1,2,3,4. So I would suggest a wrapper to memcpy() to produce a compile-time error when we try to copy arrays of different sizes:

#define Memcpy(a,b) do {                    /* copy arrays */       \
    ASSERT(sizeof(a) == sizeof(b) &&        /* a static assert */   \
           sizeof(a) != sizeof((a) + 0));   /* no pointers */       \
    memcpy((a), (b), sizeof (b));           /* & unnecesary */      \
    } while (0)                             /* no return value */

This macro will generate a compile-time error if your array is of length 1. Which is perhaps a feature.

Because we are using a macro, the C99 compound literal seems to need an extra pair of parentheses:

Memcpy(myarray, ((int[]) { 1, 2, 3, 4 }));

Here ASSERT() is a 'static assert'. If you don't already have your own, I use the following on a number of platforms:

#define CONCAT_TOKENS(a, b) a ## b
#define EXPAND_THEN_CONCAT(a,b) CONCAT_TOKENS(a, b)
#define ASSERT(e) enum {EXPAND_THEN_CONCAT(ASSERT_line_,__LINE__) = 1/!!(e)}
#define ASSERTM(e,m) /* version of ASSERT() with message */ \
    enum{EXPAND_THEN_CONCAT(m##_ASSERT_line_,__LINE__)=1/!!(e)}

To expand on Berry's answer, that setting the access level to protected allows __get and __set to be used with explicitly declared properties (when accessed outside the class, at least) and the speed being considerably slower, I'll quote a comment from another question on this topic and make a case for using it anyway:

I agree that __get is more slow to a custom get function (doing the same things), this is 0.0124455 the time for __get() and this 0.0024445 is for custom get() after 10000 loops. – Melsi Nov 23 '12 at 22:32 Best practice: PHP Magic Methods __set and __get

According to Melsi's tests, considerably slower is about 5 times slower. That is definitely considerably slower, but also note that the tests show that you can still access a property with this method 10,000 times, counting time for loop iteration, in roughly 1/100 of a second. It is considerably slower in comparison with actual get and set methods defined, and that is an understatement, but in the grand scheme of things, even 5 times slower is never actually slow.

The computing time of the operation is still negligible and not worth considering in 99% of real world applications. The only time it should really be avoided is when you're actually going to be accessing the properties over 10,000 times in a single request. High traffic sites are doing something really wrong if they can't afford throwing a few more servers up to keep their applications running. A single line text ad on the footer of a high traffic site where the access rate becomes an issue could probably pay for a farm of 1,000 servers with that line of text. The end user is never going to be tapping their fingers wondering what is taking the page so long to load because your application's property access takes a millionth of a second.

I say this speaking as a developer coming from a background in .NET, but invisible get and set methods to the consumer is not .NET's invention. They simply aren't properties without them, and these magic methods are PHP's developer's saving grace for even calling their version of properties "properties" at all. Also, the Visual Studio extension for PHP does support intellisense with protected properties, with that trick in mind, I'd think. I would think with enough developers using the magic __get and __set methods in this way, the PHP developers would tune up the execution time to cater to the developer community.

Edit: In theory, protected properties seemed like it'd work in most situation. In practice, it turns out that there's a lot of times you're going to want to use your getters and setters when accessing properties within the class definition and extended classes. A better solution is a base class and interface for when extending other classes, so you can just copy the few lines of code from the base class into the implementing class. I'm doing a bit more with my project's base class, so I don't have an interface to provide right now, but here is the untested stripped down class definition with magic property getting and setting using reflection to remove and move the properties to a protected array:

/** Base class with magic property __get() and __set() support for defined properties. */
class Component {
    /** Gets the properties of the class stored after removing the original
     * definitions to trigger magic __get() and __set() methods when accessed. */
    protected $properties = array();

    /** Provides property get support. Add a case for the property name to
     * expand (no break;) or replace (break;) the default get method. When
     * overriding, call parent::__get($name) first and return if not null,
     * then be sure to check that the property is in the overriding class
     * before doing anything, and to implement the default get routine. */
    public function __get($name) {
        $caller = array_shift(debug_backtrace());
        $max_access = ReflectionProperty::IS_PUBLIC;
        if (is_subclass_of($caller['class'], get_class($this)))
            $max_access = ReflectionProperty::IS_PROTECTED;
        if ($caller['class'] == get_class($this))
            $max_access = ReflectionProperty::IS_PRIVATE;
        if (!empty($this->properties[$name])
            && $this->properties[$name]->class == get_class()
            && $this->properties[$name]->access <= $max_access)
            switch ($name) {
                default:
                    return $this->properties[$name]->value;
            }
    }

    /** Provides property set support. Add a case for the property name to

     * overriding, call parent::__set($name, $value) first, then be sure to

     * and to implement the default set routine. */
    public function __set($name, $value) {
        $caller = array_shift(debug_backtrace());
        $max_access = ReflectionProperty::IS_PUBLIC;

            $max_access = ReflectionProperty::IS_PRIVATE;
        if (!empty($this->properties[$name])
            && $this->properties[$name]->class == get_class()
            && $this->properties[$name]->access <= $max_access)
            switch ($name) {
                default:
                    $this->properties[$name]->value = $value;
            }
    }

    /** Constructor for the Component. Call first when overriding. */
    function __construct() {
        // Removing and moving properties to $properties property for magic
        // __get() and __set() support.
        $reflected_class = new ReflectionClass($this);
        $properties = array();
        foreach ($reflected_class->getProperties() as $property) {
            if ($property->isStatic()) { continue; }
            $properties[$property->name] = (object)array(
                'name' => $property->name, 'value' => $property->value
                , 'access' => $property->getModifier(), 'class' => get_class($this));
            unset($this->{$property->name}); }
        $this->properties = $properties;
    }
}

My apologies if there are any bugs in the code.

As others have pointed out, you are modifying a collection that you are iterating over and that's what's causing the error. The offending code is below:

foreach (KeyValuePair<int, int> kvp in rankings)
{
    .....

    if((double)(similarModules/modules.Count)>0.6)
    {
        rankings[kvp.Key] = rankings[kvp.Key] + 4;  // <--- This line is the problem
    }
    .....

What may not be obvious from the code above is where the Enumerator comes from. In a blog post from a few years back about Eric Lippert provides an example of what a foreach loop gets expanded to by the compiler. The generated code will look something like:

{
    IEnumerator<int> e = ((IEnumerable<int>)values).GetEnumerator(); // <-- This
                                                       // is where the Enumerator
                                                       // comes from.
    try
    { 
        int m; // OUTSIDE THE ACTUAL LOOP in C# 4 and before, inside the loop in 5
        while(e.MoveNext())
        {
            // loop code goes here
        }
    }
    finally
    { 
      if (e != null) ((IDisposable)e).Dispose();
    }
}

If you look up the MSDN documentation for IEnumerable (which is what GetEnumerator() returns) you will see:

Enumerators can be used to read the data in the collection, but they cannot be used to modify the underlying collection.

Which brings us back to what the error message states and the other answers re-state, you're modifying the underlying collection.

It is not possible to send POST parameters in the url in a starightforward manner. POST request in itself means sending information in the body.

I found a fairly simple way to do this. Use Postman by Google, which allows you to specify the content-type(a header field) as application/json and then provide name-value pairs as parameters.

You can find clear directions at [2020-09-04: broken link - see comment] http://docs.brightcove.com/en/video-cloud/player-management/guides/postman.html

Just use your url in the place of theirs.

Hope it helps

From what I understand, your question is not really about whether to use jQuery or not. It's rather: Is it better to bind events inline in HTML or through event listeners?

Inline binding is deprecated. Moreover this way you can only bind one function to a certain event.

Therefore I recommend using event listeners. This way, you'll be able to bind many functions to a single event and to unbind them later if needed. Consider this pure JavaScript code:

querySelector('#myDiv').addEventListener('click', function () {
    // Some code...
});

This works in most modern browsers.

However, if you already include jQuery in your project — just use jQuery: .on or .click function.

You say

The string is exactly what was written to the file (with the addition of a "\0" at the end, but I don't think that even does anything).

In fact, it does do something (it causes your code to throw a FormatException:"Invalid character in a Base-64 string") because the Convert.FromBase64String does not consider "\0" to be a valid Base64 character.

  byte[] data1 = Convert.FromBase64String("AAAA\0"); // Throws exception
  byte[] data2 = Convert.FromBase64String("AAAA");   // Works

Solution: Get rid of the zero termination. (Maybe call .Trim("\0"))

Notes:

The MSDN docs for Convert.FromBase64String say it will throw a FormatException when

The length of s, ignoring white space characters, is not zero or a multiple of 4.

-or-

The format of s is invalid. s contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.

and that

The base 64 digits in ascending order from zero are the uppercase characters 'A' to 'Z', lowercase characters 'a' to 'z', numerals '0' to '9', and the symbols '+' and '/'.

The following query is very helpful

select  * from
(select count(*) used from pg_stat_activity) q1,
(select setting::int res_for_super from pg_settings where name=$$superuser_reserved_connections$$) q2,
(select setting::int max_conn from pg_settings where name=$$max_connections$$) q3;

I had the same problem while designing a template in Mailjet. Solution of the problem was minified CSS code inside <style> tags.

You'll want to include double quotes (") before and after the imageUrl like this:

$('myOjbect').css('background-image', 'url("' + imageUrl + '")');

This way, if the image has spaces it will still be set as a property.

Here is a working example:

http://zavitax.wordpress.com/2012/12/17/logging-in-with-google-service-account-in-c-jwt/

It took quite some time to collect the pieces scattered over the web, the docs are rather incomplete...

You can use setTimeout to run the function/command once or setInterval to run the function/command at specified intervals.

var a = setTimeout("alert('run just one time')",500);
var b = setInterval("alert('run each 3 seconds')",3000);

//To abort the interval you can use this:
clearInterval(b);

Each time you do e.nextElement() you skip one. So you skip two elements in each iteration of your loop.

Your last one was almost there:

trait A {
    function calc($v) {
        return $v+1;
    }
}

class MyClass {
    use A {
        calc as protected traitcalc;
    }

    function calc($v) {
        $v++;
        return $this->traitcalc($v);
    }
}

The trait is not a class. You can't access its members directly. It's basically just automated copy and paste...

For tools like jarsigner which is implemented in Java.

If you want to DUMP your inserts into an .sql file:

1. cd to the location which you want to .sql file to be located
2. pg_dump --column-inserts --data-only --table=<table> <database> > my_dump.sql

Note the > my_dump.sql command. This will put everything into a sql file named my_dump

Also check whether you have any falsy value or not. Angularjs will insert an empty option if you do have falsy value. I struggled for 2 days just due to falsy value. I hope it will be helpful for someone.

I had options as [0, 1] and initially I was set the model to 0 due to that it was inserted empty option. Workaround for this was ["0" , "1"].

We were getting an error related to this after a recent release of code to one of our development environments. We have an application that is a child of another application. This relationship has been working fine for YEARS until yesterday.

The problem:
We were getting a yellow stack trace error due to duplicate keys being entered. This is because both the web.config for the child and parent applications had this key. But this existed for many years like this without change. Why all of sudden its an issue now?

The solution:
The reason this was never a problem is because the keys AND values were always the same. Yesterday we updated our SQL connection strings to include the Application Name in the connection string. This made the string unique and all of sudden started to fail.

Without doing any research on the exact reason for this, I have to assume that when the child application inherits the parents web.config values, it ignores identical key/value pairs.

We were able to solve it by wrapping the connection string like this

    <location path="." inheritInChildApplications="false">
        <connectionStrings>
            <!-- Updated connection strings go here -->
        </connectionStrings>
    </location>

Edit: I forgot to mention that I added this in the PARENTS web.config. I didn't have to modify the child's web.config.

Thanks for everyones help on this, saved our butts.

Here's my awesome script, it creates a new terminal window if needed and switches to the directory Finder is in if Finder is frontmost. It has all the machinery you need to run commands.

on run
    -- Figure out if we want to do the cd (doIt)
    -- Figure out what the path is and quote it (myPath)
    try
        tell application "Finder" to set doIt to frontmost
        set myPath to finder_path()
        if myPath is equal to "" then
            set doIt to false
        else
            set myPath to quote_for_bash(myPath)
        end if
    on error
        set doIt to false
    end try

    -- Figure out if we need to open a window
    -- If Terminal was not running, one will be opened automatically
    tell application "System Events" to set isRunning to (exists process "Terminal")

    tell application "Terminal"
        -- Open a new window
        if isRunning then do script ""
        activate
        -- cd to the path
        if doIt then
            -- We need to delay, terminal ignores the second do script otherwise
            delay 0.3
            do script " cd " & myPath in front window
        end if
    end tell
end run

on finder_path()
    try
        tell application "Finder" to set the source_folder to (folder of the front window) as alias
        set thePath to (POSIX path of the source_folder as string)
    on error -- no open folder windows
        set thePath to ""
    end try

    return thePath
end finder_path

-- This simply quotes all occurrences of ' and puts the whole thing between 's
on quote_for_bash(theString)
    set oldDelims to AppleScript's text item delimiters
    set AppleScript's text item delimiters to "'"
    set the parsedList to every text item of theString
    set AppleScript's text item delimiters to "'\\''"
    set theString to the parsedList as string
    set AppleScript's text item delimiters to oldDelims
    return "'" & theString & "'"
end quote_for_bash

if just everything could be this simple...

#logo {background:url(../global_images/csg-4b15a4b83d966.png) no-repeat top left;background-position:0 -825px;float:left;height:48px;position:relative;width:112px}

#logo a {padding-top:48px; display:block;}



<div id="logo"><a href="../../index.html"></a></div>

just think a little outside the box ;-)

Since my system (like so many other systems) had various network interfaces.InetAddress.getLocalHost() or Inet4Address.getLocalHost() simply returned one that I did not desire. Therefore I had to use this naive approach.

InetAddress[] allAddresses = Inet4Address.getAllByName("YourComputerHostName");
        InetAddress desiredAddress;
        //In order to find the desired Ip to be routed by other modules (WiFi adapter)
        for (InetAddress address :
                allAddresses) {
            if (address.getHostAddress().startsWith("192.168.2")) {
                desiredAddress = address;
            }
        }
// Use the desired address for whatever purpose.

Just be careful that in this approach I already knew that my desired IP address is in 192.168.2 subnet.

In my case the best solution including the requirement for authentication is:

username="admin"
new_password="helloworld"

PGPASSWORD=DB_PASSWORD \
  psql -h HOSTNAME -U DB_USERNAME -d DATABASE_NAME -c \
  "UPDATE user SET password = '$new_password' WHERE username = '$username'"

This command will update a password of a user e.g. for recovery case.

Info: The trade-off here is that you need to keep in mind that the password will be visible in the bash history. For more information see here.

Update: I'm running the databse in a docker container and there I just need the commmand: docker exec -i container_name psql -U postgres -d postgres -c "$SQL_COMMAND"

I know the OP is using zoo here, but I found this thread googling for a standard ts solution for the same problem. So I thought I'd add a zoo-free answer for ts as well.

# create an example Date 
date_1 <- as.Date("1990-01-01")
# extract year
as.numeric(format(date_1, "%Y"))
# extract month
as.numeric(format(date_1, "%m"))

The following worked pretty well for me:

ping -s my_host_name

What I want is a way to merge my stashed changes with the current changes

Here is another option to do it:

git stash show -p|git apply
git stash drop

git stash show -p will show the patch of last saved stash. git apply will apply it. After the merge is done, merged stash can be dropped with git stash drop.

A good reason, which you have sort of touched on, is that once the CSRF cookie has been received, it is then available for use throughout the application in client script for use in both regular forms and AJAX POSTs. This will make sense in a JavaScript heavy application such as one employed by AngularJS (using AngularJS doesn't require that the application will be a single page app, so it would be useful where state needs to flow between different page requests where the CSRF value cannot normally persist in the browser).

Consider the following scenarios and processes in a typical application for some pros and cons of each approach you describe. These are based on the Synchronizer Token Pattern.

Request Body Approach

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it to a hidden field.
5. User submits form.
6. Server checks hidden field matches session stored token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Cookie can actually be HTTP Only.

Disadvantages:

• All forms must output the hidden field in HTML.
• Any AJAX POSTs must also include the value.
• The page must know in advance that it requires the CSRF token so it can include it in the page content so all pages must contain the token value somewhere, which could make it time consuming to implement for a large site.

Custom HTTP Header (downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form (token is sent via hidden field).
7. Server checks hidden field matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work without an AJAX request to get the header value.
• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CSRF token, so it will mean an extra round trip each time.
• Might as well have simply output the token to the page which would save the extra request.

Custom HTTP Header (upstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it in the page content somewhere.
5. User submits form via AJAX (token is sent via header).
6. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must include the header.

Custom HTTP Header (upstream & downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form via AJAX (token is sent via header) .
7. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CRSF token, so it will mean an extra round trip each time.

Set-Cookie

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Server generates CSRF token, stores it against the user session and outputs it to a cookie.
5. User submits form via AJAX or via HTML form.
6. Server checks custom header (or hidden form field) matches session stored token.
7. Cookie is available in browser for use in additional AJAX and form requests without additional requests to server to retrieve the CSRF token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Doesn't necessarily require an AJAX request to get the cookie value. Any HTTP request can retrieve it and it can be appended to all forms/AJAX requests via JavaScript.
• Once the CSRF token has been retrieved, as it is stored in a cookie the value can be reused without additional requests.

Disadvantages:

• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The cookie will be submitted for every request (i.e. all GETs for images, CSS, JS, etc, that are not involved in the CSRF process) increasing request size.
• Cookie cannot be HTTP Only.

So the cookie approach is fairly dynamic offering an easy way to retrieve the cookie value (any HTTP request) and to use it (JS can add the value to any form automatically and it can be employed in AJAX requests either as a header or as a form value). Once the CSRF token has been received for the session, there is no need to regenerate it as an attacker employing a CSRF exploit has no method of retrieving this token. If a malicious user tries to read the user's CSRF token in any of the above methods then this will be prevented by the Same Origin Policy. If a malicious user tries to retrieve the CSRF token server side (e.g. via curl) then this token will not be associated to the same user account as the victim's auth session cookie will be missing from the request (it would be the attacker's - therefore it won't be associated server side with the victim's session).

As well as the Synchronizer Token Pattern there is also the Double Submit Cookie CSRF prevention method, which of course uses cookies to store a type of CSRF token. This is easier to implement as it does not require any server side state for the CSRF token. The CSRF token in fact could be the standard authentication cookie when using this method, and this value is submitted via cookies as usual with the request, but the value is also repeated in either a hidden field or header, of which an attacker cannot replicate as they cannot read the value in the first place. It would be recommended to choose another cookie however, other than the authentication cookie so that the authentication cookie can be secured by being marked HttpOnly. So this is another common reason why you'd find CSRF prevention using a cookie based method.

if(!arrayName[index]){
     // do stuff
}

Extension method based on Linq

public static void DeleteRows(this DataTable dt, Func<DataRow, bool> predicate)
{
    foreach (var row in dt.Rows.Cast<DataRow>().Where(predicate).ToList())
        row.Delete();
}

Then use:

DataTable dt = GetSomeData();
dt.DeleteRows(r => r.Field<double>("Amount") > 123.12 && r.Field<string>("ABC") == "XYZ");

I might have a solution for the video as background, stretched to the browser-width or height, (but the video will still preserve the aspect ratio, couldnt find a solution for that yet.):

Put the video right after the body-tag with style="width:100%;". Right afterwords, put a "bodydummy"-tag:

<body>
<video id="bgVideo" autoplay poster="videos/poster.png">
    <source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
    <source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
    <source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>    
</video>

<img id="bgImg" src="videos/poster.png" />

<!-- This image stretches exactly to the browser width/height and lies behind the video-->

<div id="bodyDummy">

Put all your content inside the bodydummy-div and put the z-indexes correctly in CSS like this:

#bgImg{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 1;
    width: 100%;
    height: 100%;
}

#bgVideo{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 2;
    width: 100%;
    height: 100%;
}

#bodyDummy{ 
    position: absolute;
    top: 0;
    left: 0;
    z-index: 3;
    overflow: auto;
    width: 100%;
    height: 100%;
}

Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.

What you want to do is fetch the value from the input and assign it to a new Date instance.

let date = document.getElementById('dateInput');

let formattedDate = new Date(date.value);

console.log(formattedDate);

You can assign "button" to role attribute of any html tag/element to make pointer over it. i.e

<html-element role="button" />

You can't use memcmp to compare structs for equality due to potential random padding characters between field in structs.

  // bad
  memcmp(&struct1, &struct2, sizeof(struct1));

The above would fail for a struct like this:

typedef struct Foo {
  char a;
  /* padding */
  double d;
  /* padding */
  char e;
  /* padding */
  int f;
} Foo ;

You have to use member-wise comparison to be safe.

Download it from here:

http://www.iis.net/downloads/microsoft/url-rewrite

or if you already have Web Platform Installer on your machine you can install it from there.

For sake of simplicity, maybe you should consider using the Requests library.

An example with json response content would be something like:

import requests
r = requests.get('https://github.com/timeline.json')
r.json()

If you look for further information, in the Quickstart section, they have lots of working examples.

EDIT:

For your specific curl translation:

import requests
url = 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere'
payload = open("request.json")
headers = {'content-type': 'application/json', 'Accept-Charset': 'UTF-8'}
r = requests.post(url, data=payload, headers=headers)

The dispatch_after function dispatches a block object to a dispatch queue after a given period of time. Use below code to perform some UI related taks after 2.0 seconds.

            let delay = 2.0
            let delayInNanoSeconds = dispatch_time(DISPATCH_TIME_NOW, Int64(delay * Double(NSEC_PER_SEC)))
            let mainQueue = dispatch_get_main_queue()

            dispatch_after(delayInNanoSeconds, mainQueue, {

                print("Some UI related task after delay")
            })

In swift 3.0 :

            let dispatchTime: DispatchTime = DispatchTime.now() + Double(Int64(2.0 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)
            DispatchQueue.main.asyncAfter(deadline: dispatchTime, execute: {

          })

Use the reindent.py script that you find in the Tools/scripts/ directory of your Python installation:

Change Python (.py) files to use 4-space indents and no hard tab characters. Also trim excess spaces and tabs from ends of lines, and remove empty lines at the end of files. Also ensure the last line ends with a newline.

Have a look at that script for detailed usage instructions.

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

You can use apache commons langs like this :

WordUtils.capitalizeFully("this is a text to be capitalize")

you can find the java doc here : WordUtils.capitalizeFully java doc

and if you want to remove the spaces in between the worlds you can use :

StringUtils.remove(WordUtils.capitalizeFully("this is a text to be capitalize")," ")

you can find the java doc for String StringUtils.remove java doc

i hope this help.

First, create your splash screen as a borderless, immovable form with your image on it, set to initially display at the center of the screen, colored the way you want. All of this can be set from within the designer; specifically, you want to:

• Set the form's ControlBox, MaximizeBox, MinimizeBox and ShowIcon properties to "False"
• Set the StartPosition property to "CenterScreen"
• Set the FormBorderStyle property to "None"
• Set the form's MinimumSize and MaximumSize to be the same as its initial Size.

Then, you need to decide where to show it and where to dismiss it. These two tasks need to occur on opposite sides of the main startup logic of your program. This could be in your application's main() routine, or possibly in your main application form's Load handler; wherever you're creating large expensive objects, reading settings from the hard drive, and generally taking a long time to do stuff behind the scenes before the main application screen displays.

Then, all you have to do is create an instance of your form, Show() it, and keep a reference to it while you do your startup initialization. Once your main form has loaded, Close() it.

If your splash screen will have an animated image on it, the window will need to be "double-buffered" as well, and you will need to be absolutely sure that all initialization logic happens outside the GUI thread (meaning you cannot have your main loading logic in the mainform's Load handler; you'll have to create a BackgroundWorker or some other threaded routine.

It's in fact almost the same in Python.. :-)

import datetime
year = datetime.date.today().year

Of course, date doesn't have a time associated, so if you care about that too, you can do the same with a complete datetime object:

import datetime
year = datetime.datetime.today().year

(Obviously no different, but you can store datetime.datetime.today() in a variable before you grab the year, of course).

One key thing to note is that the time components can differ between 32-bit and 64-bit pythons in some python versions (2.5.x tree I think). So you will find things like hour/min/sec on some 64-bit platforms, while you get hour/minute/second on 32-bit.

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

I was looking for an answer to this myself. S3 appears to only support redirects, you can't just rewrite the URL and silently return a different resource. I'm considering using my build script to simply make copies of my index.html in all of the required path locations. Maybe that will work for you too.

Try this way, almost same.. but that's what I did, and working.

<configuration>
    <system.web>
       <customErrors mode="On" defaultRedirect="apperror.aspx">
          <error statusCode="404" redirect="404.aspx" />
          <error statusCode="500" redirect="500.aspx" />
       </customErrors>
    </system.web>
</configuration> 

or try to change the 404 error page from IIS settings, if required urgently.

Just in case this helps anyone else; this error can occur in Visual Studio if you have a View as the open tab, and that tab depends on a parameter.

Close the current view and start your application and the app will start 'Normally'; if you have a view open, Visual Studio interprets this as you want to run the current view.

$this->db->like() automatically adds the %s and escapes the string. So all you need is

$this->db->like('title', $query);
$res = $this->db->get('film');

Here is an UIImage extension in Swift 2 based on the accepted answer by @Anomie. It uses a clearer switch case. It also takes the optional value returned by CGBitmapContextCreateImage() into consideration.

extension UIImage {
    func rotateImageByOrientation() -> UIImage {
        // No-op if the orientation is already correct
        guard self.imageOrientation != .Up else {
            return self
        }

        // We need to calculate the proper transformation to make the image upright.
        // We do it in 2 steps: Rotate if Left/Right/Down, and then flip if Mirrored.
        var transform = CGAffineTransformIdentity;

        switch (self.imageOrientation) {
        case .Down, .DownMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.width, self.size.height)
            transform = CGAffineTransformRotate(transform, CGFloat(M_PI))

        case .Left, .LeftMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.width, 0)
            transform = CGAffineTransformRotate(transform, CGFloat(M_PI_2))

        case .Right, .RightMirrored:
            transform = CGAffineTransformTranslate(transform, 0, self.size.height)
            transform = CGAffineTransformRotate(transform, CGFloat(-M_PI_2))

        default:
            break
        }

        switch (self.imageOrientation) {
        case .UpMirrored, .DownMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.width, 0)
            transform = CGAffineTransformScale(transform, -1, 1)

        case .LeftMirrored, .RightMirrored:
            transform = CGAffineTransformTranslate(transform, self.size.height, 0)
            transform = CGAffineTransformScale(transform, -1, 1)

        default:
            break
        }

        // Now we draw the underlying CGImage into a new context, applying the transform
        // calculated above.
        let ctx = CGBitmapContextCreate(nil, Int(self.size.width), Int(self.size.height),
            CGImageGetBitsPerComponent(self.CGImage), 0,
            CGImageGetColorSpace(self.CGImage),
            CGImageGetBitmapInfo(self.CGImage).rawValue)
        CGContextConcatCTM(ctx, transform)
        switch (self.imageOrientation) {
        case .Left, .LeftMirrored, .Right, .RightMirrored:
            CGContextDrawImage(ctx, CGRectMake(0,0,self.size.height,self.size.width), self.CGImage)

        default:
            CGContextDrawImage(ctx, CGRectMake(0,0,self.size.width,self.size.height), self.CGImage)
        }

        // And now we just create a new UIImage from the drawing context
        if let cgImage = CGBitmapContextCreateImage(ctx) {
            return UIImage(CGImage: cgImage)
        } else {
            return self
        }
    }
}

Bootstrap has a few functions that can be called manually on modals:

$('#myModal').modal('toggle');
$('#myModal').modal('show');
$('#myModal').modal('hide');

You can see more here: Bootstrap modal component

Specifically the methods section.

So you would need to change:

$('#my-modal').modal({
    show: 'false'
}); 

to:

$('#myModal').modal('show'); 

If you're looking to make a custom popup of your own, here's a suggested video from another community member:

try this:

declare @foo    varchar(7),
        @oldFoo varchar(7)

set @foo = '138'
set @oldFoo = '0' + @foo

ALT+ENTER was far from eclipse habit ,in IDEA for me mouse over did not work , so in setting>IDESetting>Keymap>Show intention actions and quick-fixes I changed it to mouse left click , It did not support mouse over! but mouse left click was OK and closest to my intention.

I wanted a function to create a comma-delimited list of question marks for JDBC purposes, and found this post. So, I decided to take two variants and see which one performed better. After 1 million iterations, the garden-variety StringBuilder took 2 seconds (fun1), and the cryptic supposedly more optimal version (fun2) took 30 seconds. What's the point of being cryptic again?

private static String fun1(int size) {
    StringBuilder sb = new StringBuilder(size * 2);
    for (int i = 0; i < size; i++) {
        sb.append(",?");
    }
    return sb.substring(1);
}

private static String fun2(int size) {
    return new String(new char[size]).replaceAll("\0", ",?").substring(1);
}

From PHP:

function OutputJs($Content) 
{   
    ob_start();
    echo $Content;
    $expires = DAY_IN_S; // 60 * 60 * 24 ... defined elsewhere
    header("Content-type: x-javascript");
    header('Content-Length: ' . ob_get_length());
    header('Cache-Control: max-age='.$expires.', must-revalidate');
    header('Pragma: public');
    header('Expires: '. gmdate('D, d M Y H:i:s', time()+$expires).'GMT');
    ob_end_flush();
    return; 
}   

works for me.

As a developer you'll probably quickly run into the situation that you don't want files cached, in which case see Help with aggressive JavaScript caching

This is a very generic question and there is a lot of ways it can be answered.

If you want to use JUnit to create the tests, you need to create your testcase class, then create individual test methods that test specific functionality of your class/module under tests (single testcase classes are usually associated with a single "production" class that is being tested) and inside these methods execute various operations and compare the results with what would be correct. It is especially important to try and cover as many corner cases as possible.

In your specific example, you could for example test the following:

1. A simple addition between two positive numbers. Add them, then verify the result is what you would expect.
2. An addition between a positive and a negative number (which returns a result with the sign of the first argument).
3. An addition between a positive and a negative number (which returns a result with the sign of the second argument).
4. An addition between two negative numbers.
5. An addition that results in an overflow.

To verify the results, you can use various assertXXX methods from the org.junit.Assert class (for convenience, you can do 'import static org.junit.Assert.*'). These methods test a particular condition and fail the test if it does not validate (with a specific message, optionally).

Example testcase class in your case (without the methods contents defined):

import static org.junit.Assert.*;

public class AdditionTests {
    @Test
    public void testSimpleAddition() { ... }


    @Test
    public void testPositiveNegativeAddition() { ... }


    @Test
    public void testNegativePositiveAddition() { ... }


    @Test
    public void testNegativeAddition() { ... }


    @Test
    public void testOverflow() { ... }
}

If you are not used to writing unit tests but instead test your code by writing ad-hoc tests that you then validate "visually" (for example, you write a simple main method that accepts arguments entered using the keyboard and then prints out the results - and then you keep entering values and validating yourself if the results are correct), then you can start by writing such tests in the format above and validating the results with the correct assertXXX method instead of doing it manually. This way, you can re-run the test much easier then if you had to do manual tests.

Usually I handle my operations within a transaction. As I've experienced, it is not enough to set the context command timeout, but the transaction needs a constructor with a timeout parameter. I had to set both time out values for it to work properly.

int? prevto = uow.Context.Database.CommandTimeout;
uow.Context.Database.CommandTimeout = 900;
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromSeconds(900))) {
...
}

At the end of the function I set back the command timeout to the previous value in prevto.

Using EF6

If all else fails, just reinitialize with an inverse of your local offset.

var timestamp = new Date();
var inverseOffset = moment(timestamp).utcOffset() * -1;
timestamp = moment().utcOffset( inverseOffset  );

timestamp.toISOString(); // This should give you the accurate UTC equivalent.

// Wait up to 5 seconds with no minimum for a UI element to be found
WebDriverWait wait = new WebDriverWait(_pagedriver, TimeSpan.FromSeconds(5));
IWebElement title = wait.Until<IWebElement>((d) =>
{
    return d.FindElement(By.ClassName("MainContentHeader"));
});

Here is how you can do it with for-in loop.

var children = element.childNodes;

for(child in children){
    console.log(children[child]);
}

As a bonus, I'd like to offer kind of a different solution to your issue. You seem to be dealing with nested dictionaries, which is usually tedious, especially when you have to check for existence of an inner key.

There are some interesting libraries regarding this on pypi, here is a quick search for you.

In your specific case, dict_digger seems suited.

>>> import dict_digger
>>> d = {
  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
  'Grapes':{'Arabian':'25','Indian':'20'} 
}

>>> print(dict_digger.dig(d, 'Apple','American'))
16
>>> print(dict_digger.dig(d, 'Grapes','American'))
None

I had similar issue, I was able to solve it using -U option along with mvn command as

mvn clean install -U

This worked for me, hope it helps.

Simple one-line answer to create a new dataframe with only numeric columns:

df.select_dtypes(include=np.number)

If you want the names of numeric columns:

df.select_dtypes(include=np.number).columns.tolist()

Complete code:

import pandas as pd
import numpy as np

df = pd.DataFrame({'A': range(7, 10),
                   'B': np.random.rand(3),
                   'C': ['foo','bar','baz'],
                   'D': ['who','what','when']})
df
#    A         B    C     D
# 0  7  0.704021  foo   who
# 1  8  0.264025  bar  what
# 2  9  0.230671  baz  when

df_numerics_only = df.select_dtypes(include=np.number)
df_numerics_only
#    A         B
# 0  7  0.704021
# 1  8  0.264025
# 2  9  0.230671

colnames_numerics_only = df.select_dtypes(include=np.number).columns.tolist()
colnames_numerics_only
# ['A', 'B']

I don't find any of these answers acceptable. In particular, the accepted answer only handles the first command line parameter and ignores the rest. The Perl program that it is trying to emulate handles all the command line parameters. So the accepted answer doesn't even answer the question. Other answers use bash extensions, add unnecessary 'cat' commands, only work for the simple case of echoing input to output, or are just unnecessarily complicated.

However, I have to give them some credit because they gave me some ideas. Here is the complete answer:

#!/bin/sh

if [ $# = 0 ]
then
        DEFAULT_INPUT_FILE=/dev/stdin
else
        DEFAULT_INPUT_FILE=
fi

# Iterates over all parameters or /dev/stdin
for FILE in "$@" $DEFAULT_INPUT_FILE
do
        while IFS= read -r LINE
        do
                # Do whatever you want with LINE here.
                echo $LINE
        done < "$FILE"
done

Use a script like the following to execute the rest or part of the script under another user:

#!/bin/sh

id

exec sudo -u transmission /bin/sh - << eof

id

eof

THIS WORK ALSO WITH Arraylist

    // Create a couple ArrayList objects and populate them
    // with some delicious fruits.
    ArrayList<String> firstList = new ArrayList<String>() {/**
         * 
         */
        private static final long serialVersionUID = 1L;

    {
        add("apple");
        add("orange");
        add("pea");
    }};

    ArrayList<String> secondList = new ArrayList<String>() {

    /**
         * 
         */
        private static final long serialVersionUID = 1L;

    {
        add("apple");
        add("orange");
        add("banana");
        add("strawberry");
    }};

    // Show the "before" lists
    System.out.println("First List: " + firstList);
    System.out.println("Second List: " + secondList);

    // Remove all elements in firstList from secondList
    secondList.removeAll(firstList);

    // Show the "after" list
    System.out.println("Result: " + secondList);

Or simply:

PRINT SUBSTRING(@SQL_InsertQuery, 1, 8000)
PRINT SUBSTRING(@SQL_InsertQuery, 8001, 16000)

public static byte[] hexToBin(String str)
    {
        int len = str.length();
        byte[] out = new byte[len / 2];
        int endIndx;

        for (int i = 0; i < len; i = i + 2)
        {
            endIndx = i + 2;
            if (endIndx > len)
                endIndx = len - 1;
            out[i / 2] = (byte) Integer.parseInt(str.substring(i, endIndx), 16);
        }
        return out;
    }

Very similar to this question, and I would suggest the same formula in column D, albeit a few changes to the ranges:

=IFERROR(VLOOKUP(C1, A:B, 2, 0), "")

If you wanted to use match, you'd have to use INDEX as well, like so:

=IFERROR(INDEX(B:B, MATCH(C1, A:A, 0)), "")

but this is really lengthy to me and you need to know how to properly use two functions (or three, if you don't know how IFERROR works)!

Note: =IFERROR() can be a substitute of =IF() and =ISERROR() in some cases :)

You need to get a reference of your form, and after that you can iterate the elements collection. So, assuming for instance:

<form method="POST" action="submit.php" id="my-form">
  ..etc..
</form>

You will have something like:

var elements = document.getElementById("my-form").elements;

for (var i = 0, element; element = elements[i++];) {
    if (element.type === "text" && element.value === "")
        console.log("it's an empty textfield")
}

Notice that in browser that would support querySelectorAll you can also do something like:

var elements = document.querySelectorAll("#my-form input[type=text][value='']")

And you will have in elements just the element that have an empty value attribute. Notice however that if the value is changed by the user, the attribute will be remain the same, so this code is only to filter by attribute not by the object's property. Of course, you can also mix the two solution:

var elements = document.querySelectorAll("#my-form input[type=text]")

for (var i = 0, element; element = elements[i++];) {
    if (element.value === "")
        console.log("it's an empty textfield")
}

You will basically save one check.

A few of the more serious problems:

• document.write (henceforth DW) does not work in XHTML

• DW does not directly modify the DOM, preventing further manipulation (trying to find evidence of this, but it's at best situational)

• DW executed after the page has finished loading will overwrite the page, or write a new page, or not work

• DW executes where encountered: it cannot inject at a given node point

• DW is effectively writing serialised text which is not the way the DOM works conceptually, and is an easy way to create bugs (.innerHTML has the same problem)

Far better to use the safe and DOM friendly DOM manipulation methods

A much more secure way to check if property exists on the object is to use empty object or object prototype to call hasOwnProperty()

var foo = {
  hasOwnProperty: function() {
    return false;
  },
  bar: 'Here be dragons'
};

foo.hasOwnProperty('bar'); // always returns false

// Use another Object's hasOwnProperty and call it with 'this' set to foo
({}).hasOwnProperty.call(foo, 'bar'); // true

// It's also possible to use the hasOwnProperty property from the Object
// prototype for this purpose
Object.prototype.hasOwnProperty.call(foo, 'bar'); // true

Reference from MDN Web Docs - Object.prototype.hasOwnProperty()

Put and Patch method are similar . But in rails it has different metod If we want to update/replace whole record then we have to use Put method. If we want to update particular record use Patch method.

This code is all you need:

   static void Main(string[] args) {
        String xml = @"
            <transactions>
                <transaction name=""Fred"" amount=""5,20"" />
                <transaction name=""John"" amount=""10,00"" />
                <transaction name=""Fred"" amount=""3,00"" />
            </transactions>";

        XDocument xmlDocument = XDocument.Parse(xml);

        var query = from x in xmlDocument.Descendants("transaction")
                    group x by x.Attribute("name").Value into g
                    select new { Name = g.Key, Amount = g.Sum(t => Decimal.Parse(t.Attribute("amount").Value)) };

        foreach (var item in query) {
            Console.WriteLine("Name: {0}; Amount: {1:C};", item.Name, item.Amount);
        }
    }

And the content is:

Name: Fred; Amount: R$ 8,20;
Name: John; Amount: R$ 10,00;

That is the way of doing this in C# - in a declarative way!

I hope this helps,

In PHP you can use:

$page = $_SERVER['PHP_SELF'];
$sec = "10";
header("Refresh: $sec; url=$page");

Or just use JavaScript's window.location.reload().

Use Sql Server Profiler (tools menu) to monitor executing queries and use activity monitor in Management studio to see how is connected and if their connection is blocking other connections.

If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.

Add a javascript class with all you KO extensions or extenders, and add the following:

ko.extenders.required = function (target, overrideMessage) {
    //add some sub-observables to our observable
    target.hasError = ko.observable();
    target.validationMessage = ko.observable();

    //define a function to do validation
    function validate(newValue) {
    target.hasError(newValue ? false : true);
    target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
    }

    //initial validation
    validate(target());

    //validate whenever the value changes
    target.subscribe(validate);

    //return the original observable
    return target;
};

Then in your viewModel extend you observable by:

self.dateOfPayment: ko.observable().extend({ required: "" }),

There are a number of examples online for this style of validation.

1. Simply Delete the pid file from rails app directory

Rails_app -> tmp -> pids -> pid file

Delete the file and run

rails start

2. For Rails 5.0 and above, you can use this command

rails restart

This works like a charm ;)

<ul class="nav nav-pills" ng-init="selectedType = 'return'">
    <li role="presentation" ng-class="{'active':selectedType === 'return'}"
        ng-click="selectedType = 'return'"><a href="#return">return

    </a></li>
    <li role="presentation" ng-class="{'active':selectedType === 'oneway'}"
        ng-click="selectedType = 'oneway'"><a href="#oneway">oneway
    </a></li>
</ul>

Regex isn't needed, nor is plugins

if (isNaN($('#Field').val() / 1) == false) {
    your code here
}

Better than all above is ever to use Standard C specification for struct initialization:

struct StructType structVar = {0};

Here are all bits zero (ever).

I'd go for regexp_replace, although I'm not 100% sure this is usable in PL/SQL

my_value := regexp_replace(my_value, '[[:space:]]*',''); 

Well basically this error is saying, that you had a unique index on a particular field for example: "email_address", so mongodb expects unique email address value for each document in the collection.

So let's say, earlier in your schema the unique index was not defined, and then you signed up 2 users with the same email address or with no email address (null value).

Later, you saw that there was a mistake. so you try to correct it by adding a unique index to the schema. But your collection already has duplicates, so the error message says that you can't insert a duplicate value again.

You essentially have three options:

1. Drop the collection

   db.users.drop();

2. Find the document which has that value and delete it. Let's say the value was null, you can delete it using:

   db.users.remove({ email_address: null });

3. Drop the Unique index:

   db.users.dropIndex(indexName)

I Hope this helped :)

Check sysobjects and syscolumns tables.

Here is a diagram of Sybase system tables.

List of all user tables:

SELECT * FROM sysobjects WHERE type = 'U'

You can change 'U' to other objects:

• C – computed column
• D – default
• F – SQLJ function
• L – log
• N – partition condition
• P – Transact-SQL or SQLJ procedure
• PR – prepare objects (created by Dynamic SQL)
• R – rule
• RI – referential constraint
• S – system table
• TR – trigger
• U – user table
• V – view
• XP – extended stored procedure

List of columns in a table:

SELECT sc.* 
FROM syscolumns sc
INNER JOIN sysobjects so ON sc.id = so.id
WHERE so.name = 'my_table_name'

d4 = dict(d1.items() + d2.items() + d3.items())

alternatively (and supposedly faster):

d4 = dict(d1)
d4.update(d2)
d4.update(d3)

Previous SO question that both of these answers came from is here.

ActiveX resolved in Chrome!
Hello all this is not the solution but the successful workaround and I have implemented as well.
This required some implementation on client machine as well that why is most suitable for intranet environment and not recommended for public sites. Even though one can implement it for public sites as well the only problem is end user has to download/implement solution.
Lets understand the key problem
Chrome cannot communicate with ActiceX
Solution: Since Chorme cannot communicate with ActiveX but still it can communicate with the API hosted on the client machine. So develop API using .Net MVC or any other technology so that through Ajax call it can communicate with the API and API communicate with the ActiveX object situated on the client machine. Since API also resides in Client machine that why there is no problem in communication. This API works as mediator between Chrome browser and ActiveX.
During API implementation you might encounter CORS issues, Use JSONP to deal with it.
