The simplest way of doing this

I urge you to read this blog post that directly addresses your problem.

Using custom model binders isn't really wise as Phil Haack pointed out (his blog post is linked in the upper blog post as well).

Basically you have three options:

1. Write a JsonValueProviderFactory and use a client side library like json2.js to communicate wit JSON directly.

2. Write a JQueryValueProviderFactory that understands the jQuery JSON object transformation that happens in $.ajax or

3. Use the very simple and quick jQuery plugin outlined in the blog post, that prepares any JSON object (even arrays that will be bound to IList<T> and dates that will correctly parse on the server side as DateTime instances) that will be understood by Asp.net MVC default model binder.

Of all three, the last one is the simplest and doesn't interfere with Asp.net MVC inner workings thus lowering possible bug surface. Using this technique outlined in the blog post will correctly data bind your strong type action parameters and validate them as well. So it is basically a win win situation.

You can use this simple query for progressive calculation :

select 
   id
  ,SomeNumt
  ,sum(SomeNumt) over(order by id ROWS between UNBOUNDED PRECEDING and CURRENT ROW) as CumSrome
from @t

You can either pass request reverse('view-name', request=request) or enclose reverse() with build_absolute_uri request.build_absolute_uri(reverse('view-name'))

Most of the time prod mode is not needed during development time. So our workaround is to only enable it when it is NOT localhost.

In your browsers' main.ts where you define your root AppModule:

const isLocal: boolean = /localhost/.test(document.location.host);
!isLocal && enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

The isLocal can also be used for other purposes like enableTracing for the RouterModule for better debugging stack trace during dev phase.

To complete Sunit's answer, you can use a selector, not to the text string but to the textColorHint. You must add this attribute on your editText:

android:textColorHint="@color/text_hint_selector"

And your text_hint_selector should be:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/hint_color" />
</selector>

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll

    private const string strconneciton = "Data Source=.;Initial Catalog=Employees;Integrated Security=True";
    SqlConnection con = new SqlConnection(strconneciton);

    private void button1_Click(object sender, EventArgs e)
    {

        con.Open();
        SqlCommand cmd = new SqlCommand("insert into EmployeeData (Name,S/O,Address,Phone,CellNo,CNICNO,LicenseNo,LicenseDistrict,LicenseValidPhoto,ReferenceName,ReferenceContactNo) values ( '" + textName.Text + "','" + textSO.Text + "','" + textAddress.Text + "','" + textPhone.Text + "','" + textCell.Text + "','" + textCNIC.Text + "','" + textLicenseNo.Text + "','" + textLicenseDistrict.Text + "','" + textLicensePhoto.Text + "','" + textReferenceName.Text + "','" + textContact.Text + "' )", con);
        cmd.ExecuteNonQuery();
        con.Close();
    }

People have mentioned make but bjam also supports a similar concept. Using bjam -jx instructs bjam to build up to x concurrent commands.

We use the same build scripts on Windows and Linux and using this option halves our build times on both platforms. Nice.

I had this happen to me after an update to a new Xcode. Running

xcode-select --install

fixed it for me.

To see all tables:

.tables

To see a particular table:

.schema [tablename]

I think that what happens is this:

focus()
   UI tasks related to pre-focus
   callbacks
       select()
   UI tasks related to focus (which unselect again)

A workaround may be calling the select() asynchronously, so that it runs completely after focus():

$("input[type=text]").focus(function() { 
    var save_this = $(this);
    window.setTimeout (function(){ 
       save_this.select(); 
    },100);
});

You can download the older SDK and install it in

Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/

folder. Logout + Login just to make sure the changes take effect and you should see the older SDK in your new XCode

The 500 (internal server error) means something went wrong on the server's side. It could be several things, but I would start by verifying that the URL and parameters are correct. Also, make sure that whatever handles the request is expecting the request as a GET and not a POST.

One useful way to learn more about what's going on is to use a tool like Fiddler which will let you watch all HTTP requests and responses so you can see exactly what you're sending and the server is responding with.

If you don't have a compelling reason to write your own Ajax code, you would be far better off using a library that handles the Ajax interactions for you. jQuery is one option.

This is my alias that works both with Python 2 and Python 3 removing all .pyc .pyo files as well __pycache__ directories recursively.

alias pyclean='find . -name "*.py[co]" -o -name __pycache__ -exec rm -rf {} +'

This is quite a misleading status. It should be called "reading and filtering data".

This means that MySQL has some data stored on the disk (or in memory) which is yet to be read and sent over. It may be the table itself, an index, a temporary table, a sorted output etc.

If you have a 1M records table (without an index) of which you need only one record, MySQL will still output the status as "sending data" while scanning the table, despite the fact it has not sent anything yet.

pure javascript:

var ctrlKeyCode = 17;
var cntrlIsPressed = false;

document.addEventListener('keydown', function(event){
    if(event.which=="17")
        cntrlIsPressed = true;
});

document.addEventListener('keyup', function(){
    if(event.which=="17")
        cntrlIsPressed = true;
});



function selectMe(mouseButton)
{
    if(cntrlIsPressed)
    {
        switch(mouseButton)
        {
            case 1:
                alert("Cntrl +  left click");
                break;
            case 2:
                alert("Cntrl + right click");
                break;
            default:
                break;
        }
    }
}

You can do this by using @ViewChild for more info check this link

With type selector

child component

@Component({
  selector: 'child-cmp',
  template: '<p>child</p>'
})
class ChildCmp {
  doSomething() {}
}

parent component

@Component({
  selector: 'some-cmp',
  template: '<child-cmp></child-cmp>',
  directives: [ChildCmp]
})
class SomeCmp {

  @ViewChild(ChildCmp) child:ChildCmp;

  ngAfterViewInit() {
    // child is set
    this.child.doSomething();
  }
}

With string selector

child component

@Component({
  selector: 'child-cmp',
  template: '<p>child</p>'
})
class ChildCmp {
  doSomething() {}
}

parent component

@Component({
  selector: 'some-cmp',
  template: '<child-cmp #child></child-cmp>',
  directives: [ChildCmp]
})
class SomeCmp {

  @ViewChild('child') child:ChildCmp;

  ngAfterViewInit() {
    // child is set
    this.child.doSomething();
  }
}

I also tried the de-compilation thing, it works but recently I found the easiest way:

1. Download and install Appium from Appium website

2. Open Appium->Android setting, choose the target apk file. And then you get everything you want, the package info, activity info.

I know it's an old question but it seems unsolved still. Follows my solution...

Simply add this global handler:

$('a').click(function()
{
     return ($(this).attr('disabled')) ? false : true;
});

Here's a quick demo: http://jsbin.com/akihik/3

you can even add a bit of css to give a different style to all the links with the disabled attribute.

e.g

a[disabled]
{
    color: grey; 
}

Anyway it seems that the disabled attribute is not valid for a tags. If you prefer to follow the w3c specs you can easily adopt an html5 compliant data-disabled attribute. In this case you have to modify the previous snippet and use $(this).data('disabled').

In my case i had to load images on radio button click, I just uses the regular onclick event and it worked for me.

 <input type="radio" name="colors" value="{{color.id}}" id="{{color.id}}-option" class="color_radion"  onclick="return get_images(this, {{color.id}})">

<script>
  function get_images(obj, color){
    console.log($("input[type='radio'][name='colors']:checked").val());

  }
  </script>

Just found a proper working solution for other guys,

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

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

and in your method you can use like

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

You can use the datedif function to find out difference in days.

=DATEDIF(A1,TODAY(),"d")

Quote from excel.datedif.com

The mysterious datedif function in Microsoft Excel

The Datedif function is used to calculate interval between two dates in days, months or years.

This function is available in all versions of Excel but is not documented. It is not even listed in the "Insert Function" dialog box. Hence it must be typed manually in the formula box. Syntax

DATEDIF( start_date, end_date, interval_unit )

start_date from date end_date to date (must be after start_date) interval_unit Unit to be used for output interval Values for interval_unit

interval_unit Description

D Number of days

M Number of complete months

Y Number of complete years

YD Number of days excluding years

MD Number of days excluding months and years

YM Number of months excluding years

Errors

Error Description

#NUM! The end_date is later than (greater than) the start_date or interval_unit has an invalid value. #VALUE! end_date or start_date is invalid.

First you need to determine the revision ID of the last known commit. You can use HEAD^ or HEAD~{1} if you know you need to reverse exactly one commit.

git reset --hard <revision_id_of_last_known_good_commit>
git push --force

[id^='someId'] will match all ids starting with someId.

[id$='someId'] will match all ids ending with someId.

[id*='someId'] will match all ids containing someId.

If you're looking for the name attribute just substitute id with name.

If you're talking about the tag name of the element I don't believe there is a way using querySelector

It's a good question... I don't want to lead you astray, so I'm open to other people's answers as much as you are. For me, it really comes down to cost of overhead and what the use of the API is. I prefer consuming web services when creating client software, however I don't like the weight of SOAP. REST, I believe, is lighter weight but I don't enjoy working with it from a client perspective nearly as much.

I'm curious as to what others think.

Here's a C99 version based on wikipedia's article about Julian Day

#include <stdio.h>

const char *wd(int year, int month, int day) {
  /* using C99 compound literals in a single line: notice the splicing */
  return ((const char *[])                                         \
          {"Monday", "Tuesday", "Wednesday",                       \
           "Thursday", "Friday", "Saturday", "Sunday"})[           \
      (                                                            \
          day                                                      \
        + ((153 * (month + 12 * ((14 - month) / 12) - 3) + 2) / 5) \
        + (365 * (year + 4800 - ((14 - month) / 12)))              \
        + ((year + 4800 - ((14 - month) / 12)) / 4)                \
        - ((year + 4800 - ((14 - month) / 12)) / 100)              \
        + ((year + 4800 - ((14 - month) / 12)) / 400)              \
        - 32045                                                    \
      ) % 7];
}

int main(void) {
  printf("%d-%02d-%02d: %s\n", 2011, 5, 19, wd(2011, 5, 19));
  printf("%d-%02d-%02d: %s\n", 2038, 1, 19, wd(2038, 1, 19));
  return 0;
}

By removing the splicing and spaces from the return line in the wd() function, it can be compacted to a 286 character single line :)

Neither of them. If you define it, it's not the default.

The default constructor is the no-argument constructor automatically generated unless you define another constructor. Any uninitialised fields will be set to their default values. For your example, it would look like this assuming that the types are String, int and int, and that the class itself is public:

public Module()
{
  super();
  this.name = null;
  this.credits = 0;
  this.hours = 0;
}

This is exactly the same as

public Module()
{}

And exactly the same as having no constructors at all. However, if you define at least one constructor, the default constructor is not generated.

Reference: Java Language Specification

If a class contains no constructor declarations, then a default constructor with no formal parameters and no throws clause is implicitly declared.

Clarification

Technically it is not the constructor (default or otherwise) that default-initialises the fields. However, I am leaving it the answer because

• the question got the defaults wrong, and
• the constructor has exactly the same effect whether they are included or not.

The ImportError message is a bit misleading because of the reference to Win32, whereas the problem was simply the opencv DLLs were not found.

This problem was solved by adding the path the opencv binaries to the Windows PATH environment variable (as an example, on my computer this path is : C:\opencv\build\bin\Release).

I have faced similar problem and found best solution . Below code works perfect for me.

        result = result.Replace(tabs, "\t\t\t\t");
        breaks = breaks + "\r";
        tabs = tabs + "\t";
    }

    // That's it.
    return result;
}
catch
{
    MessageBox.Show("Error");
    return source;
}

}

Escape characters such as \n and \r had to be removed first because they cause regexes to cease working as expected.

Moreover, to make the result string display correctly in the textbox, one might need to split it up and set textbox's Lines property instead of assigning to Text property.

this.txtResult.Lines = StripHTML(this.txtSource.Text).Split("\r".ToCharArray());

On my Ubuntu LAMP installation, I solved this problem with the following 2 changes.

1. Enable mod_rewrite on the apache server: sudo a2enmod rewrite.
2. Edit /etc/apache2/apache2.conf, changing the "AllowOverride" directive for the /var/www directory (which is my main document root): AllowOverride All

Then restart the Apache server: service apache2 restart

Can use generics to combine arrays. Following code can easily be expanded to three arrays. This way you never need to duplicate code for different type of arrays. Some of the above answers seem overly complex to me.

private static T[] CombineTwoArrays<T>(T[] a1, T[] a2)
    {
        T[] arrayCombined = new T[a1.Length + a2.Length];
        Array.Copy(a1, 0, arrayCombined, 0, a1.Length);
        Array.Copy(a2, 0, arrayCombined, a1.Length, a2.Length);
        return arrayCombined;
    }

<%= link_to root_path do %><%= image_tag("Search.png",:alt=>'Vivek',:title=>'Vivek',:class=>'dock-item')%><%= content_tag(:span, "Search").html_safe%><% end %>

I don't know why but for me text-align:center; only works with:

text-align: grid;

OR

display: inline-grid;

I checked and no one style is overriding.

My structure:

<ul>
    <li>
        <a>ElementToCenter</a>
    </li>
</ul>

I have found this works ONLY in Chrome (where it's red) and not Safari and all other browsers (where it's green)...

.style {
color: green;
(-bracket-:hack;
    color: red;
);
}

From http://mynthon.net/howto/webdev/css-hacks-for-google-chrome.htm

I had similar issue. I resolved it with just CSS.

Basically Object-fit: cover helps you achieve the task of maintaining the aspect ratio while positioning an image inside a div.

But the problem was Object-fit: cover was not working in IE and it was taking 100% width and 100% height and aspect ratio was distorted. In other words image zooming effect wasn't there which I was seeing in chrome.

The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

Once it is in the centre, I give to the image,

// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;

// For Horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;

This makes the image get the effect of Object-fit:cover.

Here is a demonstration of the above logic.

https://jsfiddle.net/furqan_694/s3xLe1gp/

This logic works in all browsers.

HTTP and redirects

Let's first recap how ASP.NET MVC works:

1. When an HTTP request comes in, it is matched against a set of routes. If a route matches the request, the controller action corresponding to the route will be invoked.
2. Before invoking the action method, ASP.NET MVC performs model binding. Model binding is the process of mapping the content of the HTTP request, which is basically just text, to the strongly typed arguments of your action method

Let's also remind ourselves what a redirect is:

An HTTP redirect is a response that the webserver can send to the client, telling the client to look for the requested content under a different URL. The new URL is contained in a Location header that the webserver returns to the client. In ASP.NET MVC, you do an HTTP redirect by returning a RedirectResult from an action.

Passing data

If you were just passing simple values like strings and/or integers, you could pass them as query parameters in the URL in the Location header. This is what would happen if you used something like

return RedirectToAction("ActionName", "Controller", new { arg = updatedResultsDocument });

as others have suggested

The reason that this will not work is that the XDocument is a potentially very complex object. There is no straightforward way for the ASP.NET MVC framework to serialize the document into something that will fit in a URL and then model bind from the URL value back to your XDocument action parameter.

In general, passing the document to the client in order for the client to pass it back to the server on the next request, is a very brittle procedure: it would require all sorts of serialisation and deserialisation and all sorts of things could go wrong. If the document is large, it might also be a substantial waste of bandwidth and might severely impact the performance of your application.

Instead, what you want to do is keep the document around on the server and pass an identifier back to the client. The client then passes the identifier along with the next request and the server retrieves the document using this identifier.

Storing data for retrieval on the next request

So, the question now becomes, where does the server store the document in the meantime? Well, that is for you to decide and the best choice will depend upon your particular scenario. If this document needs to be available in the long run, you may want to store it on disk or in a database. If it contains only transient information, keeping it in the webserver's memory, in the ASP.NET cache or the Session (or TempData, which is more or less the same as the Session in the end) may be the right solution. Either way, you store the document under a key that will allow you to retrieve the document later:

int documentId = _myDocumentRepository.Save(updatedResultsDocument);

and then you return that key to the client:

return RedirectToAction("UpdateConfirmation", "ApplicationPoolController ", new { id = documentId });

When you want to retrieve the document, you simply fetch it based on the key:

 public ActionResult UpdateConfirmation(int id)
 {
      XDocument doc = _myDocumentRepository.GetById(id);

      ConfirmationModel model = new ConfirmationModel(doc);

      return View(model);
 }

The :: instead of REM was preferably used in the days that computers weren't very fast. REM'ed line are read and then ingnored. ::'ed line are ignored all the way. This could speed up your code in "the old days". Further more after a REM you need a space, after :: you don't.

And as said in the first comment: you can add info to any line you feel the need to

SET DATETIME=%DTS:~0,8%-%DTS:~8,6% ::Makes YYYYMMDD-HHMMSS

As for the skipping of parts. Putting REM in front of every line can be rather time consuming. As mentioned using GOTO to skip parts is an easy way to skip large pieces of code. Be sure to set a :LABEL at the point you want the code to continue.

SOME CODE

GOTO LABEL  ::REM OUT THIS LINE TO EXECUTE THE CODE BETWEEN THIS GOTO AND :LABEL

SOME CODE TO SKIP
.
LAST LINE OF CODE TO SKIP

:LABEL
CODE TO EXECUTE

Source code of clear shows the reason why the newly added data gets the first position.

 public void clear() {
    modCount++;

    // Let gc do its work
    for (int i = 0; i < size; i++)
        elementData[i] = null;

    size = 0;
    }

clear() is faster than removeAll() by the way, first one is O(n) while the latter is O(n_2)

A very unique solution for this problem is using git log:

git log -p -M --follow --stat -- path/to/your/file

As explained by Andre here

Run the command using the windows command prompt from your main Python library source. Example.

C:\Python27\python.exe directoryToFile\yourprogram.py

# To do it for all names
df[] <- lapply( df, factor) # the "[]" keeps the dataframe structure
 col_names <- names(df)
# to do it for some names in a vector named 'col_names'
df[col_names] <- lapply(df[col_names] , factor)

Explanation. All dataframes are lists and the results of [ used with multiple valued arguments are likewise lists, so looping over lists is the task of lapply. The above assignment will create a set of lists that the function data.frame.[<- should successfully stick back into into the dataframe, df

Another strategy would be to convert only those columns where the number of unique items is less than some criterion, let's say fewer than the log of the number of rows as an example:

cols.to.factor <- sapply( df, function(col) length(unique(col)) < log10(length(col)) )
df[ cols.to.factor] <- lapply(df[ cols.to.factor] , factor)

The following series of steps might be helpful:

1. Open Windows Explorer
2. In the top-left corner, click "Organize"
3. select "Folder and Search Options"
4. Switch to the "View" tab
5. Scroll down and uncheck "Hide file extensions for known file types"
6. Click OK
7. Now find the dll file
8. Right-click on it and select "Rename"
9. Change the extension(what comes after the last .) and change it to .exe

If your page has a section for Scripts such as the following, then ensure you refer to your Jquery library from inside this section.

@section Scripts 
{ 
   <script src="~/Scripts/jquery-ui.js" type="text/javascript"></script>
} 

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspet ratio */
  min-width: 100%;
  min-height: 100%;
}

To add a new cookie, use HttpServletResponse.addCookie(Cookie). The Cookie is pretty much a key value pair taking a name and value as strings on construction.

You can check instance of Chart by using Chart.instances. This will give you all the charts instances. Now you can iterate on that instances and and change the data, which is present inside config. suppose you have only one chart in your page.

for (var _chartjsindex in Chart.instances) {
/* 
 * Here in the config your actual data and options which you have given at the 
   time of creating chart so no need for changing option only you can change data
*/
 Chart.instances[_chartjsindex].config.data = [];
 // here you can give add your data
 Chart.instances[_chartjsindex].update();
 // update will rewrite your whole chart with new value
 }

You must first import the functions:

import org.apache.spark.sql.functions._

Then you can use them like this:

val df = CSV.load(args(0))
val sumSteps =  df.agg(sum("steps")).first.get(0)

You can also cast the result if needed:

val sumSteps: Long = df.agg(sum("steps").cast("long")).first.getLong(0)

Edit:

For multiple columns (e.g. "col1", "col2", ...), you could get all aggregations at once:

val sums = df.agg(sum("col1").as("sum_col1"), sum("col2").as("sum_col2"), ...).first

Edit2:

For dynamically applying the aggregations, the following options are available:

• Applying to all numeric columns at once:

df.groupBy().sum()

• Applying to a list of numeric column names:

val columnNames = List("col1", "col2")
df.groupBy().sum(columnNames: _*)

• Applying to a list of numeric column names with aliases and/or casts:

val cols = List("col1", "col2")
val sums = cols.map(colName => sum(colName).cast("double").as("sum_" + colName))
df.groupBy().agg(sums.head, sums.tail:_*).show()

I know its old post but still I want to contribute
Above will not work if you have data format like this
'YYYMMDD'

For example:

Dt
20151104

So I tried following in order to get the desired result.

select cast(Left('20151104', 4)||'-'||substring('20151104',5,2)||'-'||substring('20151104', 7,2) as date) from SYSIBM.SYSDUMMY1;

Additionally, If you want to run the query from MS SQL linked server to DB2(To display only 100 rows).

    SELECT top 100 * from OPENQUERY([Linked_Server_Name],
    'select cast(Left(''20151104'', 4)||''-''||substring(''20151104'',5,2)||''-''||substring(''20151104'', 7,2) as date) AS Dt 
    FROM SYSIBM.SYSDUMMY1')

Result after above query:

Dt
2015-11-04

Hope this helps for others.

An alternative is Joda-Time.

Use DateTime

DateTime date = new DateTime(new Date());
date.isBeforeNow();
or
date.isAfterNow();

The other way to tackle it is to use this code snippet:

JSON.parse(JSON.stringify(response)).data

This feels so wrong but it works

This can be done with MySQL, although it's highly unintuitive:

CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
  DECLARE a,b INT;
  DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
  DECLARE CONTINUE HANDLER FOR NOT FOUND
  SET b = 1;
  OPEN cur_1;
  REPEAT
    FETCH cur_1 INTO a;
    UNTIL b = 1
  END REPEAT;
  CLOSE cur_1;
  SET return_val = a;
END;//

Check out this guide: mysql-storedprocedures.pdf

what about Result_* there also are generated in the loop (because i don't think it's possible to add to the csv file)

i will go like this ; generate all the data at one rotate the matrix write in the file:

A = []

A.append(range(1, 5))  # an Example of you first loop

A.append(range(5, 9))  # an Example of you second loop

data_to_write = zip(*A)

# then you can write now row by row

One way to do it is to set the image you want to display as a background in a container (td, div, span etc) and then adjust background-position to get the sprite you want.

i had the same issue. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check named pipes is enabled.

synchronized is method level/block level access restriction modifier. It will make sure that one thread owns the lock for critical section. Only the thread,which own a lock can enter synchronized block. If other threads are trying to access this critical section, they have to wait till current owner releases the lock.

volatile is variable access modifier which forces all threads to get latest value of the variable from main memory. No locking is required to access volatile variables. All threads can access volatile variable value at same time.

A good example to use volatile variable : Date variable.

Assume that you have made Date variable volatile. All the threads, which access this variable always get latest data from main memory so that all threads show real (actual) Date value. You don't need different threads showing different time for same variable. All threads should show right Date value.

Have a look at this article for better understanding of volatile concept.

Lawrence Dol cleary explained your read-write-update query.

Regarding your other queries

When is it more suitable to declare variables volatile than access them through synchronized?

You have to use volatile if you think all threads should get actual value of the variable in real time like the example I have explained for Date variable.

Is it a good idea to use volatile for variables that depend on input?

Answer will be same as in first query.

Refer to this article for better understanding.

To get the location of a script being sourced, you can use utils::getSrcDirectory or utils::getSrcFilename. So changing the working directory to that of the current file can be done with:

setwd(getSrcDirectory()[1])

This does not work in RStudio if you Run the code rather than Sourceing it. For that, you need to use rstudioapi::getActiveDocumentContext.

setwd(dirname(rstudioapi::getActiveDocumentContext()$path))

This second solution requires that you are using RStudio as your IDE, of course.

Use value instanceof YourClass

Adding answer as this was the top hit when searching for "drop multiple columns in r":

The general version of the single column removal, e.g df$column1 <- NULL, is to use list(NULL):

df[ ,c('column1', 'column2')] <- list(NULL)

This also works for position index as well:

df[ ,c(1,2)] <- list(NULL)

This is a more general drop and as some comments have mentioned, removing by indices isn't recommended. Plus the familiar negative subset (used in other answers) doesn't work for columns given as strings:

> iris[ ,-c("Species")]
Error in -"Species" : invalid argument to unary operator

The Array has declared without intializing the values and if you want to insert values by itterating the loop this code will work.

Public Class Program
{

public static void main(String args[])

{
 //Array Intialization
 int my[] = new int[6];

 for(int i=0;i<=5;i++)

{

//Storing array values in array
my[i]= i;

//Printing array values

System.out.println(my[i]);

}

}

}

In the first situation, Num2 is extending the class Num and since you are not redefining the special method named __init__() in Num2, it gets inherited from Num.

When a class defines an __init__() method, class instantiation automatically invokes __init__() for the newly-created class instance.

In the second situation, since you are redefining __init__() in Num2 you need to explicitly call the one in the super class (Num) if you want to extend its behavior.

class Num2(Num):
    def __init__(self,num):
        Num.__init__(self,num)
        self.n2 = num*2

You could use super(ChildClass, self).__init__()

class BaseClass(object):
    def __init__(self, *args, **kwargs):
        pass

class ChildClass(BaseClass):
    def __init__(self, *args, **kwargs):
        super(ChildClass, self).__init__(*args, **kwargs)

Your indentation is incorrect, here's the modified code:

class Car(object):
    condition = "new"

    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg

class ElectricCar(Car):
    def __init__(self, battery_type, model, color, mpg):
        self.battery_type=battery_type
        super(ElectricCar, self).__init__(model, color, mpg)

car = ElectricCar('battery', 'ford', 'golden', 10)
print car.__dict__

Here's the output:

{'color': 'golden', 'mpg': 10, 'model': 'ford', 'battery_type': 'battery'}

I know the question has been answered but one more way to solve this is using the pillow library. To convert a whole directory of images:

from PIL import Image
import os


def makePdf(imageDir, SaveToDir):
     '''
        imageDir: Directory of your images
        SaveToDir: Location Directory for your pdfs
    '''
    os.chdir(imageDir)
    try:
        for j in os.listdir(os.getcwd()):
            os.chdir(imageDir)
            fname, fext = os.path.splitext(j)
            newfilename = fname + ".pdf"
            im = Image.open(fname + fext)
            if im.mode == "RGBA":
                im = im.convert("RGB")
            os.chdir(SaveToDir)
            if not os.path.exists(newfilename):
                im.save(newfilename, "PDF", resolution=100.0)
    except Exception as e:
        print(e)

imageDir = r'____' # your imagedirectory path
SaveToDir = r'____' # diretory in which you want to save the pdfs
makePdf(imageDir, SaveToDir)

For using it on an single image:

From PIL import Image
import os

filename = r"/Desktop/document/dog.png"
im = Image.open(filename)
if im.mode == "RGBA":
    im = im.convert("RGB")
new_filename = r"/Desktop/document/dog.pdf"
if not os.path.exists(new_filename):
    im.save(new_filename,"PDF",resolution=100.0)

If it's reasonable to alter the original Map data structure to be serialized to better represent the actual value wanted to be serialized, that's probably a decent approach, which would possibly reduce the amount of Jackson configuration necessary. For example, just remove the null key entries, if possible, before calling Jackson. That said...

To suppress serializing Map entries with null values:

Before Jackson 2.9

you can still make use of WRITE_NULL_MAP_VALUES, but note that it's moved to SerializationFeature:

mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);

Since Jackson 2.9

The WRITE_NULL_MAP_VALUES is deprecated, you can use the below equivalent:

mapper.setDefaultPropertyInclusion(
   JsonInclude.Value.construct(Include.ALWAYS, Include.NON_NULL))

To suppress serializing properties with null values, you can configure the ObjectMapper directly, or make use of the @JsonInclude annotation:

mapper.setSerializationInclusion(Include.NON_NULL);

or:

@JsonInclude(Include.NON_NULL)
class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To handle null Map keys, some custom serialization is necessary, as best I understand.

A simple approach to serialize null keys as empty strings (including complete examples of the two previously mentioned configurations):

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.SerializerProvider;

public class JacksonFoo
{
  public static void main(String[] args) throws Exception
  {
    Map<String, Foo> foos = new HashMap<String, Foo>();
    foos.put("foo1", new Foo("foo1"));
    foos.put("foo2", new Foo(null));
    foos.put("foo3", null);
    foos.put(null, new Foo("foo4"));

    // System.out.println(new ObjectMapper().writeValueAsString(foos));
    // Exception: Null key for a Map not allowed in JSON (use a converting NullKeySerializer?)

    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);
    mapper.setSerializationInclusion(Include.NON_NULL);
    mapper.getSerializerProvider().setNullKeySerializer(new MyNullKeySerializer());
    System.out.println(mapper.writeValueAsString(foos));
    // output: 
    // {"":{"bar":"foo4"},"foo2":{},"foo1":{"bar":"foo1"}}
  }
}

class MyNullKeySerializer extends JsonSerializer<Object>
{
  @Override
  public void serialize(Object nullKey, JsonGenerator jsonGenerator, SerializerProvider unused) 
      throws IOException, JsonProcessingException
  {
    jsonGenerator.writeFieldName("");
  }
}

class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To suppress serializing Map entries with null keys, further custom serialization processing would be necessary.

You can do this

String stringUrl = "https://ipinfo.io/ip";
//String stringUrl = "http://whatismyip.akamai.com/";
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(MainActivity.instance);
//String url ="http://www.google.com";

// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, stringUrl,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                // Display the first 500 characters of the response string.
                Log.e(MGLogTag, "GET IP : " + response);

            }
        }, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        IP = "That didn't work!";
    }
});

// Add the request to the RequestQueue.
queue.add(stringRequest);

you can user canvans with jsPDF

import jsPDF from 'jspdf';
import html2canvas from 'html2canvas';

 _exportPdf = () => {

     html2canvas(document.querySelector("#capture")).then(canvas => {
        document.body.appendChild(canvas);  // if you want see your screenshot in body.
        const imgData = canvas.toDataURL('image/png');
        const pdf = new jsPDF();
        pdf.addImage(imgData, 'PNG', 0, 0);
        pdf.save("download.pdf"); 
    });

 }

and you div with id capture is:

example

<div id="capture">

  <span>How can hellp you</span>
</div>

It's not possible to decrypt MD5 hash which created. You need all information to decrypt the MD5 value which was used during encryption.

You can use AES algorithm to encrypt and decrypt

C is a only programming language its used in system programming. but embedded C is used to implement the projects like real time applications

<context:annotation-config>

Only resolves the @Autowired and @Qualifer annotations, that's all, it about the Dependency Injection, There are other annotations that do the same job, I think how @Inject, but all about to resolve DI through annotations.

Be aware, even when you have declared the <context:annotation-config> element, you must declare your class how a Bean anyway, remember we have three available options

• XML: <bean>
• @Annotations: @Component, @Service, @Repository, @Controller
• JavaConfig: @Configuration, @Bean

Now with

<context:component-scan>

It does two things:

• It scans all the classes annotated with @Component, @Service, @Repository, @Controller and @Configuration and create a Bean
• It does the same job how <context:annotation-config> does.

Therefore if you declare <context:component-scan>, is not necessary anymore declare <context:annotation-config> too.

Thats all

A common scenario was for example declare only a bean through XML and resolve the DI through annotations, for example

<bean id="serviceBeanA" class="com.something.CarServiceImpl" />
<bean id="serviceBeanB" class="com.something.PersonServiceImpl" />
<bean id="repositoryBeanA" class="com.something.CarRepository" />
<bean id="repositoryBeanB" class="com.something.PersonRepository" />

We have only declared the beans, nothing about <constructor-arg> and <property>, the DI is configured in their own classes through @Autowired. It means the Services use @Autowired for their Repositories components and the Repositories use @Autowired for the JdbcTemplate, DataSource etc..components

Add multiple lines : use @

string query = @"SELECT foo, bar
FROM table
WHERE id = 42";

Add String Values to the middle : use $

string text ="beer";
string query = $"SELECT foo {text} bar ";

Multiple line string Add Values to the middle: use $@

string text ="Customer";
string query = $@"SELECT foo, bar
FROM {text}Table
WHERE id = 42";

document.getElementById("someFormId").elements;

This collection will also contain <select>, <textarea> and <button> elements (among others), but you probably want that.

Had a similar issue while installing "Lua" in OS X using homebrew. I guess it could be useful for other users facing similar issue in homebrew.

On running the command:

$ brew install lua

The command returned an error:

Error: /usr/local/opt/lua is not a valid keg
(in general the error can be of /usr/local/opt/ is not a valid keg

FIXED it by deleting the file/directory it is referring to, i.e., deleting the "/usr/local/opt/lua" file.

root-user # rm -rf /usr/local/opt/lua

And then running the brew install command returned success.

Microsoft replace SWITCH, IFS and IFVALUES with CHOOSE only function.

Take a look at the Tiny But Strong templating system. It's generally used for templating HTML but there's an extension that works with XML files. I use this extensively for creating reports where I can have one code file and two template files - htm and xml - and the user can then choose whether to send a report to screen or spreadsheet.

Another advantage is you don't have to code the xml from scratch, in some cases I've been wanting to export very large complex spreadsheets, and instead of having to code all the export all that is required is to save an existing spreadsheet in xml and substitute in code tags where data output is required. It's a quick and a very efficient way to work.

Right click on your my computer icon and the CPU will be listed on the properties page. Or open device manager and look at the CPU. It must be an Intel processor that supports VT and NX bit (XD) - you can check your CPU # at http://ark.intel.com

  <fruit name="Apple" colour="Green" />
  <fruit name="Banana" colour="Yellow" />
</fruits>

JavaScript:

function getFruits(xml) {
  var fruits = xml.getElementsByTagName("fruits")[0];
  if (fruits) {
    var fruitsNodes = fruits.childNodes;
    if (fruitsNodes) {
      for (var i = 0; i < fruitsNodes.length; i++) {
        var name = fruitsNodes[i].getAttribute("name");
        var colour = fruitsNodes[i].getAttribute("colour");
        alert("Fruit " + name + " is coloured " + colour);
      }
    }
  }
}

May be there no need for JS. You can achieve this with css also. Write like this:

.flyout {
    position: absolute;
    width: 1000px;
    height: 450px;
    background: red;
    overflow: hidden;
    z-index: 10000;
    display: none;
}
#menu:hover + .flyout {
    display: block;
}

loadImage("http://relinjose.com/directory/filename.png");

Here you go

void loadImage(String image_location) {
    URL imageURL = null;
    if (image_location != null) {
        try {
            imageURL = new URL(image_location);         
            HttpURLConnection connection = (HttpURLConnection) imageURL
                    .openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream inputStream = connection.getInputStream();
            bitmap = BitmapFactory.decodeStream(inputStream);// Convert to bitmap
            ivdpfirst.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    } else {
        //set any default
    }
}

The Selenium client bindings will try to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

  export PATH=$PATH:/path/to/geckodriver
  

• On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.

All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2 to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.

To use Marionette in your tests you will need to update your desired capabilities to use it.

Java :

As exception is clearly saying you need to download latest geckodriver.exe from here and set downloaded geckodriver.exe path where it's exists in your computer as system property with with variable webdriver.gecko.driver before initiating marionette driver and launching firefox as below :-

//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities); 

And for Selenium3 use as :-

WebDriver driver = new FirefoxDriver();

If you're still in trouble follow this link as well which would help you to solving your problem

.NET :

var driver = new FirefoxDriver(new FirefoxOptions());

Python :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox

Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true

JavaScript (Node.js) :

const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;

var capabilities = Capabilities.firefox();

// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

Using RemoteWebDriver

If you want to use RemoteWebDriver in any language, this will allow you to use Marionette in Selenium Grid.

Python:

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps

Java :

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

.NET

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();

// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.

You can download latest geckodriver executable to support latest firefox from here

I think the problem is with the datatype of the data you are passing Caused by: java.sql.SQLException: Invalid column type: 1111 check the datatypes you pass with the actual column datatypes may be there can be some mismatch or some constraint violation with null

If you need rock solid integrity, have both tables in one database, and use an FK constraint. If your parent table is in another database, nothing prevents anyone from restoring that parent database from an old backup, and then you have orphans.

This is why FK between databases is not supported.

Update Swift 4.1

Here we create a struct to implement the Tuple usage and validate the OTP text length. That needs to be of 2 fields for this example.

struct ValidateOTP {
var code: String
var isValid: Bool }

func validateTheOTP() -> ValidateOTP {
    let otpCode = String(format: "%@%@", txtOtpField1.text!, txtOtpField2.text!)
    if otpCode.length < 2 {
        return ValidateOTP(code: otpCode, isValid: false)
    } else {
        return ValidateOTP(code: otpCode, isValid: true)
    }
}

Usage:

let isValidOTP = validateTheOTP()
    if isValidOTP.isValid { print(" valid OTP") } else {   self.alert(msg: "Please fill the valid OTP", buttons: ["Ok"], handler: nil)
    }

Hope it helps!

Thanks

For linux/unix OS, you can use the shell syntax

const shell = require('child_process').execSync ; 

const currentPath= `/path/to/name.png`;
const newPath= `/path/to/another_name.png`;

shell(`mv ${currentPath} ${newPath}`);

That's it!

I've got it, finally!

<?php

function mysql_get_prim_key($table){
$sql = "SHOW INDEX FROM $table WHERE Key_name = 'PRIMARY'";
$gp = mysql_query($sql);
$cgp = mysql_num_rows($gp);
if($cgp > 0){
// Note I'm not using a while loop because I never use more than one prim key column
$agp = mysql_fetch_array($gp);
extract($agp);
return($Column_name);
}else{
return(false);
}
}

?>

Here's some sample code based on the book Learning Python by Mark Lutz that addresses your question:

import sys
temp = sys.stdout                 # store original stdout object for later
sys.stdout = open('log.txt', 'w') # redirect all prints to this log file
print("testing123")               # nothing appears at interactive prompt
print("another line")             # again nothing appears. it's written to log file instead
sys.stdout.close()                # ordinary file object
sys.stdout = temp                 # restore print commands to interactive prompt
print("back to normal")           # this shows up in the interactive prompt

Opening log.txt in a text editor will reveal the following:

testing123
another line

$("input[type=text][value=]")

After trying a lots of version I found this the most logical.

Note that text is case-sensitive.

You’re looking for urllib.parse.urlencode

import urllib.parse

params = {'username': 'administrator', 'password': 'xyz'}
encoded = urllib.parse.urlencode(params)
# Returns: 'username=administrator&password=xyz'

If you want to be a little bit fancier you can also create it as an html list to create something like bullets or numbers using ul or ol.

<ul>
<li>Line 1</li>
<li>Line 2</li>
</ul>

On Linux, I had this error and fixed it by running sudo update-ca-certificates.

You can read more about IE8 and HTML 5 support here:

http://blogs.msdn.com/giorgio/archive/2009/11/29/ie8-and-html-5.aspx

In my case, some of my rows didn't have the same number of columns as the header. Example, Header has 10 columns, and one of your rows has 8 or 9 columns. (Columns = Count number of you delimiter characters in each line)

The problem is in this line:

with pattern.findall(row) as f:

You are using the with statement. It requires an object with __enter__ and __exit__ methods. But pattern.findall returns a list, with tries to store the __exit__ method, but it can't find it, and raises an error. Just use

f = pattern.findall(row)

instead.

One can use the getmonth and getday methods to get only the date.

Here I attach my solution:

var fullDate = new Date(); console.log(fullDate);_x000D_
var twoDigitMonth = fullDate.getMonth() + "";_x000D_
if (twoDigitMonth.length == 1)_x000D_
    twoDigitMonth = "0" + twoDigitMonth;_x000D_
var twoDigitDate = fullDate.getDate() + "";_x000D_
if (twoDigitDate.length == 1)_x000D_
    twoDigitDate = "0" + twoDigitDate;_x000D_
var currentDate = twoDigitDate + "/" + twoDigitMonth + "/" + fullDate.getFullYear(); console.log(currentDate);

A CRC is pretty simple; you take a polynomial represented as bits and the data, and divide the polynomial into the data (or you represent the data as a polynomial and do the same thing). The remainder, which is between 0 and the polynomial is the CRC. Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the algorithm.

The way to understand CRCs is to try to compute a few using a short piece of data (16 bits or so) with a short polynomial -- 4 bits, perhaps. If you practice this way, you'll really understand how you might go about coding it.

If you're doing it frequently, a CRC is quite slow to compute in software. Hardware computation is much more efficient, and requires just a few gates.

Also, you can see the build dependencies in the file setup.cfg

Go strings are not null terminated, and to remove the last char of a string you can simply do:

s = s[:len(s)-1]

In Kotlin, you can do:

ContextCompat.getColor(requireContext(), R.color.stage_hls_fallback_snackbar)

if requireContext() is accessible from where you are calling the function. I was getting an error when trying

ContextCompat.getColor(context, R.color.stage_hls_fallback_snackbar)

The default behaviour is false:

By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup.

I suggest reading up

This error occurred to me when I was debugging the PHP header() function:

header('Location: /aaa/bbb/ccc'); // error

If I use a relative path it works:

header('Location: aaa/bbb/ccc'); // success, but not what I wanted

However when I use an absolute path like /aaa/bbb/ccc, it gives the exact error:

Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

It appears the header function redirects internally without going HTTP at all which is weird. After some tests and trials, I found the solution of adding exit after header():

header('Location: /aaa/bbb/ccc');
exit;

And it works properly.

When app is release some time that case https://developers.facebook.com/apps/{$appid}/alerts/ "Your app has been placed into development mode due to an invalid Privacy Policy." can change you app from release mode to development mode so check the Privacy Policy

Another thing that people may find useful...make sure to leave off ".py" from your module name. For example, if you are trying to generate documentation for 'original' in 'original.py':

yourcode_dir$ pydoc -w original.py
no Python documentation found for 'original.py'

yourcode_dir$ pydoc -w original
wrote original.html

Thanks to dee for the answer above with the Scrape() subroutine. The code worked perfectly as written, and I was able to then convert the code to work with the specific website I am trying to scrape.

I do not have enough reputation to upvote or to comment, but I do actually have some minor improvements to add to dee's answer:

1. You will need to add the VBA Reference via "Tools\References" to "Microsoft HTML Object Library in order for the code to compile.

2. I commented out the Browser.Visible line and added the comment as follows

   'if you need to debug the browser page, uncomment this line:
   'Browser.Visible = True
   

3. And I added a line to close the browser before Set Browser = Nothing:

   Browser.Quit
   

Thanks again dee!

ETA: this works on machines with IE9, but not machines with IE8. Anyone have a fix?

Found the fix myself, so came back here to post it. The ClassName function is available in IE9. For this to work in IE8, you use querySelectorAll, with a dot preceding the class name of the object you are looking for:

'Set repList = doc.getElementsByClassName("reportList") 'only works in IE9, not in IE8
Set repList = doc.querySelectorAll(".reportList")       'this works in IE8+

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

If it is possible in your case, you could make your methods method1(arg1) ... method7() protected instead of private so they could be accesible from test class within the same package. Then you can simply test all theese methods separately.

The other answers are fine, but this is a little cleaner, in that it only gives the values like you would get from a DISTINCT query, without any cruft from Django.

>>> set(ProductOrder.objects.values_list('category', flat=True))
{u'category1', u'category2', u'category3', u'category4'}

or

>>> list(set(ProductOrder.objects.values_list('category', flat=True)))
[u'category1', u'category2', u'category3', u'category4']

And, it works without PostgreSQL.

This is less efficient than using a .distinct(), presuming that DISTINCT in your database is faster than a python set, but it's great for noodling around the shell.

nmap is a useful tool for this kind of thing

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

Answered my own question:

IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a colon (:).

So that's 39 characters max.

Change Minute to be 0. That's it :)

Example

I use this to open a workbook and then copy that workbook's data to the template.

Private Sub CommandButton24_Click()
Set Template = ActiveWorkbook
 With Application.FileDialog(msoFileDialogOpen)
    .InitialFileName = "I:\Group - Finance" ' Yu can select any folder you want
    .Filters.Clear
    .Title = "Your Title"
    If Not .Show Then
        MsgBox "No file selected.": Exit Sub
    End If
    Workbooks.OpenText .SelectedItems(1)

'The below is to copy the file into a new sheet in the workbook and paste those values in sheet 1

    Set myfile = ActiveWorkbook
    ActiveWorkbook.Sheets(1).Copy after:=ThisWorkbook.Sheets(1)
    myfile.Close
    Template.Activate
    ActiveSheet.Cells.Select
    Selection.Copy
    Sheets("Sheet1").Select
    Cells.Select
    ActiveSheet.Paste

End With

You can fprintf to stderr, which is unbuffered, instead. Or you can flush stdout when you want to. Or you can set stdout to unbuffered.

On 2013-05-10, Guido agreed to accept PEP 435 into the Python 3.4 standard library. This means that Python finally has builtin support for enumerations!

There is a backport available for Python 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4. It's on Pypi as enum34.

Declaration:

>>> from enum import Enum
>>> class Color(Enum):
...     red = 1
...     green = 2
...     blue = 3

Representation:

>>> print(Color.red)
Color.red
>>> print(repr(Color.red))
<Color.red: 1>

Iteration:

>>> for color in Color:
...   print(color)
...
Color.red
Color.green
Color.blue

Programmatic access:

>>> Color(1)
Color.red
>>> Color['blue']
Color.blue

For more information, refer to the proposal. Official documentation will probably follow soon.

I was working with EasyRepro, and when I debugged my code it was clicking on the element which is visible and enabled, and not navigating as expected. But finally I understood the root cause for the issue.

My Chrome was zoomed out 90%

Once i reset the zoom level, it clicked on the correct element and successfully navigated to next page.

Building on top of Tomas's answer, this is the best approach of finding the location tap position as an integer I found:

adb shell getevent -l | grep ABS_MT_POSITION --line-buffered | awk '{a = substr($0,54,8); sub(/^0+/, "", a); b = sprintf("0x%s",a); printf("%d\n",strtonum(b))}'

Use adb shell getevent -l to get a list of events, the using grep for ABS_MT_POSITION (gets the line with touch events in hex) and finally use awk to get the relevant hex values, strip them of zeros and convert hex to integer. This continuously prints the x and y coordinates in the terminal only when you press on the device.

You can then use this adb shell command to send the command:

adb shell input tap x y

You can't pass parameters like this - the success object maps to an anonymous function with one parameter and that's the received data. Create a function outside of the for loop which takes (data, i) as parameters and perform the code there:

function image_link(data, i) {
   $(data).find("a:contains(.jpg)").each(function(){                                
       new Image().src = url[i] + $(this).attr("href");
   }
}
...
success: function(data){
    image_link(data, i)
}

To use the strict ISO8601, you can use the s (Sortable) format string:

 myDate.ToString("s"); // example 2009-06-15T13:45:30

It's a short-hand to this custom format string:

myDate.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss");

And of course, you can build your own custom format strings.

i faced this same, i check in in program and feature. there was an update has install for jdk1.8 which is not compatible with my old setting(jdk1.6.0) for ant in eclipse. I install that update. right now, my ant project is build success.

Try it, hope this will be helpful.

To change database owner:

ALTER AUTHORIZATION ON DATABASE::YourDatabaseName TO sa

As of SQL Server 2014 you can still use sp_changedbowner as well, even though Microsoft promised to remove it in the "future" version after SQL Server 2012. They removed it from SQL Server 2014 BOL though.

flush() will synchronize your database with the current state of object/objects held in the memory but it does not commit the transaction. So, if you get any exception after flush() is called, then the transaction will be rolled back. You can synchronize your database with small chunks of data using flush() instead of committing a large data at once using commit() and face the risk of getting an OutOfMemoryException.

commit() will make data stored in the database permanent. There is no way you can rollback your transaction once the commit() succeeds.

here's a better function

def strxor(a, b):     # xor two strings of different lengths
    if len(a) > len(b):
        return "".join([chr(ord(x) ^ ord(y)) for (x, y) in zip(a[:len(b)], b)])
    else:
        return "".join([chr(ord(x) ^ ord(y)) for (x, y) in zip(a, b[:len(a)])])

You need to use the CONCAT() function in MySQL for string concatenation:

UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;

One thing I did and it works wonders is to read both objects into HashMap and then compare with a regular assertEquals(). It will call the equals() method of the hashmaps, which will recursively compare all objects inside (they will be either other hashmaps or some single value object like a string or integer). This was done using Codehaus' Jackson JSON parser.

assertEquals(mapper.readValue(expectedJson, new TypeReference<HashMap<String, Object>>(){}), mapper.readValue(actualJson, new TypeReference<HashMap<String, Object>>(){}));

A similar approach can be used if the JSON object is an array instead.

You need to have org/name dirs at /usr/share/stuff and place your org.name package sources at this dir.

Below is the simple way to create blank line with line size. Here we can adjust size of the blank line. Try this one.

           <TextView
            android:id="@id/textView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="5dp"/>

With ES6 , use the spread operator ... :

DEMO

var arr = [23, 45, 12, 67];
arr = [34, ...arr]; // RESULT : [34,23, 45, 12, 67]

console.log(arr)

A way that has worked for me personally, is using the recyclerview's adapter methods to deal with changes in it's items.

It would go in a way similar to this, create a method in your custom recycler's view somewhat like this:

public void modifyItem(final int position, final Model model) {
    mainModel.set(position, model);
    notifyItemChanged(position);
}

Since expression is boolean:

return expression;

JSON

JSON (JavaScript Object Notation) is a convenient way to transport data between applications, especially when the destination is a JavaScript application.

Example:

Here is a minimal example that uses JSON as the transport for the server response. The client makes an Ajax request with the jQuery shorthand function $.getJSON. The server generates a hash, formats it as JSON and returns this to the client. The client formats this and puts it in a page element.

Server:

get '/json' do
 content_type :json
 content = { :response  => 'Sent via JSON',
            :timestamp => Time.now,
            :random    => rand(10000) }
 content.to_json
end

Client:

var url = host_prefix + '/json';
$.getJSON(url, function(json){
  $("#json-response").html(JSON.stringify(json, null, 2));
});

Output:

  {
   "response": "Sent via JSON",
   "timestamp": "2014-06-18 09:49:01 +0000",
   "random": 6074
  }

JSONP (JSON with Padding)

JSONP is a simple way to overcome browser restrictions when sending JSON responses from different domains from the client.

The only change on the client side with JSONP is to add a callback parameter to the URL

Server:

get '/jsonp' do
 callback = params['callback']
 content_type :js
 content = { :response  => 'Sent via JSONP',
            :timestamp => Time.now,
            :random    => rand(10000) }
 "#{callback}(#{content.to_json})"
end

Client:

var url = host_prefix + '/jsonp?callback=?';
$.getJSON(url, function(jsonp){
  $("#jsonp-response").html(JSON.stringify(jsonp, null, 2));
});

Output:

 {
  "response": "Sent via JSONP",
  "timestamp": "2014-06-18 09:50:15 +0000",
  "random": 364
}

If you wanna get the uploaded file name, use $_FILES["file"]["name"]

But If you wanna read the uploaded file you should use $_FILES["file"]["tmp_name"], because tmp_name is a temporary copy of your uploaded file and it's easier than using

$_FILES["file"]["name"] // This name includes a file path, which makes file read process more complex

Because font doesn't have color, you need a panel to make a backgound color and give the foreground color for both JLabel (if you use JLabel) and JPanel to make font color, like example below :

JLabel lblusr = new JLabel("User name : ");
lblusr.setForeground(Color.YELLOW);

JPanel usrPanel = new JPanel();
Color maroon = new Color (128, 0, 0);
usrPanel.setBackground(maroon);
usrPanel.setOpaque(true);
usrPanel.setForeground(Color.YELLOW);
usrPanel.add(lblusr);

The background color of label is maroon with yellow font color.

To my knowledge, you can't mock constructors with mockito, only methods. But according to the wiki on the Mockito google code page there is a way to mock the constructor behavior by creating a method in your class which return a new instance of that class. then you can mock out that method. Below is an excerpt directly from the Mockito wiki:

Pattern 1 - using one-line methods for object creation

To use pattern 1 (testing a class called MyClass), you would replace a call like

   Foo foo = new Foo( a, b, c );

with

   Foo foo = makeFoo( a, b, c );

and write a one-line method

   Foo makeFoo( A a, B b, C c ) { 
        return new Foo( a, b, c );
   }

It's important that you don't include any logic in the method; just the one line that creates the object. The reason for this is that the method itself is never going to be unit tested.

When you come to test the class, the object that you test will actually be a Mockito spy, with this method overridden, to return a mock. What you're testing is therefore not the class itself, but a very slightly modified version of it.

Your test class might contain members like

  @Mock private Foo mockFoo;
  private MyClass toTest = spy(new MyClass());

Lastly, inside your test method you mock out the call to makeFoo with a line like

  doReturn( mockFoo )
      .when( toTest )
      .makeFoo( any( A.class ), any( B.class ), any( C.class ));

You can use matchers that are more specific than any() if you want to check the arguments that are passed to the constructor.

If you're just wanting to return a mocked object of your class I think this should work for you. In any case you can read more about mocking object creation here:

http://code.google.com/p/mockito/wiki/MockingObjectCreation

\u0000 is the default value for char type in Java

As others mentioned, you can use comparison to check the value of an uninitialized variable.

char ch;
if(ch==0)
    System.out.println("Default value is the null character");

We used this:

<meta http-equiv="Content-Security-Policy" content="default-src gap://ready file://* *; style-src 'self' http://* https://* 'unsafe-inline'; script-src 'self' http://* https://* 'unsafe-inline' 'unsafe-eval'">

I'm using a old version of Hibernate (3.3.0) with a newest version of OpenEJB (4.6.0). My solution was:

EntityManagerImpl entityManager = (EntityManagerImpl)em.getDelegate();
Session session = entityManager.getSession();
Connection connection = session.connection();
Statement statement = null;
try {
    statement = connection.createStatement();
    statement.execute(sql);
    connection.commit();
} catch (SQLException e) {
    throw new RuntimeException(e);
}

I had an error after that:

Commit can not be set while enrolled in a transaction

Because this code above was inside a EJB Controller (you can't commit inside a transaction). I annotated the method with @TransactionAttribute(value = TransactionAttributeType.NOT_SUPPORTED) and the problem was gone.

I have changed the java installation path from c:\Program Files (x86)\java to another folder like c:\java\jdk1.7 and updated the %Java_HOME% and path values accordingly,it worked.

example

%JAVA_HOME% = C:\java\JDK1.7

path-C:\java\JDK1.7\bin; 

Try

//re:*[. ='match']

One of the most common errors that I found developing Android Apps is the “java.lang.OutOfMemoryError: Bitmap Size Exceeds VM Budget” error. I found this error frequently on activities using lots of bitmaps after changing orientation: the Activity is destroyed, created again and the layouts are “inflated” from the XML consuming the VM memory available for bitmaps.

Bitmaps on the previous activity layout are not properly de-allocated by the garbage collector because they have crossed references to their activity. After many experiments I found a quite good solution for this problem.

First, set the “id” attribute on the parent view of your XML layout:

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:id="@+id/RootView"
     >
     ...

Then, on the onDestroy() method of your Activity, call the unbindDrawables() method passing a reference to the parent View and then do a System.gc().

    @Override
    protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(findViewById(R.id.RootView));
    System.gc();
    }

    private void unbindDrawables(View view) {
        if (view.getBackground() != null) {
        view.getBackground().setCallback(null);
        }
        if (view instanceof ViewGroup) {
            for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            unbindDrawables(((ViewGroup) view).getChildAt(i));
            }
        ((ViewGroup) view).removeAllViews();
        }
    }

This unbindDrawables() method explores the view tree recursively and:

1. Removes callbacks on all the background drawables
2. Removes children on every viewgroup

You should make x and y numpy arrays, not lists:

x = np.array([0.46,0.59,0.68,0.99,0.39,0.31,1.09,
              0.77,0.72,0.49,0.55,0.62,0.58,0.88,0.78])
y = np.array([0.315,0.383,0.452,0.650,0.279,0.215,0.727,0.512,
              0.478,0.335,0.365,0.424,0.390,0.585,0.511])

With this change, it produces the expect plot. If they are lists, m * x will not produce the result you expect, but an empty list. Note that m is anumpy.float64 scalar, not a standard Python float.

I actually consider this a bit dubious behavior of Numpy. In normal Python, multiplying a list with an integer just repeats the list:

In [42]: 2 * [1, 2, 3]
Out[42]: [1, 2, 3, 1, 2, 3]

while multiplying a list with a float gives an error (as I think it should):

In [43]: 1.5 * [1, 2, 3]
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-43-d710bb467cdd> in <module>()
----> 1 1.5 * [1, 2, 3]
TypeError: can't multiply sequence by non-int of type 'float'

The weird thing is that multiplying a Python list with a Numpy scalar apparently works:

In [45]: np.float64(0.5) * [1, 2, 3]
Out[45]: []

In [46]: np.float64(1.5) * [1, 2, 3]
Out[46]: [1, 2, 3]

In [47]: np.float64(2.5) * [1, 2, 3]
Out[47]: [1, 2, 3, 1, 2, 3]

So it seems that the float gets truncated to an int, after which you get the standard Python behavior of repeating the list, which is quite unexpected behavior. The best thing would have been to raise an error (so that you would have spotted the problem yourself instead of having to ask your question on Stackoverflow) or to just show the expected element-wise multiplication (in which your code would have just worked). Interestingly, addition between a list and a Numpy scalar does work:

In [69]: np.float64(0.123) + [1, 2, 3]
Out[69]: array([ 1.123,  2.123,  3.123])

I would like to add an example of prototypical inheritance with javascript to @Scott Driscoll answer. We'll be using classical inheritance pattern with Object.create() which is a part of EcmaScript 5 specification.

First we create "Parent" object function

function Parent(){

}

Then add a prototype to "Parent" object function

 Parent.prototype = {
 primitive : 1,
 object : {
    one : 1
   }
}

Create "Child" object function

function Child(){

}

Assign child prototype (Make child prototype inherit from parent prototype)

Child.prototype = Object.create(Parent.prototype);

Assign proper "Child" prototype constructor

Child.prototype.constructor = Child;

Add method "changeProps" to a child prototype, which will rewrite "primitive" property value in Child object and change "object.one" value both in Child and Parent objects

Child.prototype.changeProps = function(){
    this.primitive = 2;
    this.object.one = 2;
};

Initiate Parent (dad) and Child (son) objects.

var dad = new Parent();
var son = new Child();

Call Child (son) changeProps method

son.changeProps();

Check the results.

Parent primitive property did not change

console.log(dad.primitive); /* 1 */

Child primitive property changed (rewritten)

console.log(son.primitive); /* 2 */

Parent and Child object.one properties changed

console.log(dad.object.one); /* 2 */
console.log(son.object.one); /* 2 */

Working example here http://jsbin.com/xexurukiso/1/edit/

More info on Object.create here https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Object/create

On your existing button code, simply insert this line before the procedure:

If MsgBox("This will erase everything! Are you sure?", vbYesNo) = vbNo Then Exit Sub

This will force it to quit if the user presses no.

The repository is not down, it looks like they've changed how they host files (I guess they have restored some old code):

Now you have to add the /package-name/ before the -

Eg:

http://registry.npmjs.org/-/npm-1.1.48.tgz
http://registry.npmjs.org/npm/-/npm-1.1.48.tgz

There are 3 ways to solve it:

• Use a complete mirror:

• Use a public proxy:

  --registry http://165.225.128.50:8000

• Host a local proxy:

  https://github.com/hughsk/npm-quickfix

git clone https://github.com/hughsk/npm-quickfix.git
cd npm-quickfix
npm set registry http://localhost:8080/
node index.js

I'd personally go with number 3 and revert to npm set registry http://registry.npmjs.org/ as soon as this get resolved.

Stay tuned here for more info: https://github.com/isaacs/npm/issues/2694

You can only do this securely on the server-side. Using the "accept" attribute is good, but must also be validated on the server side lest users be able to cURL to your script without that limitation.

I suggest that you: discard any non-image file, warn the user, and redisplay the form.

Step 1, delete all the *.DS_store files. One can run

git rm -f *.DS_Store

but be aware that rm -f can be a bit dangerous if you have a typo! Step two: add

*.DS_Store
.DS_Store

to .gitignore. This worked for me!

Current version 1.4.0 has clearBtn option:

$('.datepicker').datepicker({
    clearBtn: true
});

Besides adding button to interface it allows to delete value from input box manually.

Short-sightedness, I'd guess.

When originally designed, interfaces were intended only to be used with instances of class

IMyInterface val = GetObjectImplementingIMyInterface();
val.SomeThingDefinedinInterface();

It was only with the introduction of interfaces as constraints for generics did adding a static method to an interface have a practical use.

(responding to comment:) I believe changing it now would require a change to the CLR, which would lead to incompatibilities with existing assemblies.

I recommend doing it with webpack (assumes you're using webpack).

Defining constants is as simple as setting the webpack config file:

var webpack = require('webpack');
module.exports = {
    plugins: [
        new webpack.DefinePlugin({
            'APP_ENV': '"dev"',
            'process.env': {
                'NODE_ENV': '"development"'
            }
        })
    ],    
};

This way you define them outside your source, and they will be available in all your files.

Try using asort().

From documentation:

asort - Sort an array and maintain index association

Description:

bool asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )

This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant.

This topic has a lot of answers already, but the one that worked best (and simplest - one line!) for me was a modification of the comment made by Neil E. Pearson from Apr 21 2013:

If you're stuck with your submit button being #submit, you can get around it by stealing another form instance's submit() method.

My modification to his method, and what worked for me:

document.createElement('form').submit.call(document.getElementById(frmProduct));

You can use SimlpeDateFormat to format your date like this:

long unixSeconds = 1372339860;
// convert seconds to milliseconds
Date date = new java.util.Date(unixSeconds*1000L); 
// the format of your date
SimpleDateFormat sdf = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss z"); 
// give a timezone reference for formatting (see comment at the bottom)
sdf.setTimeZone(java.util.TimeZone.getTimeZone("GMT-4")); 
String formattedDate = sdf.format(date);
System.out.println(formattedDate);

The pattern that SimpleDateFormat takes if very flexible, you can check in the javadocs all the variations you can use to produce different formatting based on the patterns you write given a specific Date. http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

• Because a Date provides a getTime() method that returns the milliseconds since EPOC, it is required that you give to SimpleDateFormat a timezone to format the date properly acording to your timezone, otherwise it will use the default timezone of the JVM (which if well configured will anyways be right)

endstring = ''
for s in list:
    endstring += s

&wmode=opaque didn't work for me (chrome 10) but &wmode=transparent cleared the issue right up.

I tried most (if not all) answers alone from above but none worked in my case.
So i combined a couple of them trying to figure out the minimum i need.

And this combination worked for me:

div.infowindow {
    font-family: Courier;
    white-space: nowrap;
    overflow: hidden; 
}

Your milage may vary. good luck.

I found this in the navbar example, and simplified it.

<ul class="nav">
  <li><a>Default</a></li>
  <li><a>Static top</a></li>
  <li><b><a>Fixed top <span class="sr-only">(current)</span></a></b></li>
</ul>

You see which one is selected (sr-only part is hidden):

• Default
• Static top
• Fixed top

You hear which one is selected if you use screen reader:

• Default
• Static top
• Fixed top (current)

As a result of this technique blind people supposed to navigate easier on your website.

There is nothing stopping you from packing the list into a delimited string and then unpacking it once you get the string from the config. If you did it this way your config section would look like:

[Section 3]
barList=item1,item2

It's not pretty but it's functional for most simple lists.

Node manages dependencies ie; third party code using package.json so that 3rd party modules names and versions can be kept stable for all installs of the project. This also helps keep the file be light-weight as only actual program code is present in the code repository. Whenever repository is cloned, for it to work(as 3rd party modules may be used in the code), you would need to install all dependencies. Use npm install on CMD within root of the project structure to complete installing all dependencies. This should resolve all dependencies issues if dependencies get properly installed.

I think the following makes a bit more sense for print strings in reverse, but maybe that's just me:

for char in reversed( myString ):  
  print( char, end = "" )

Just to augment the other answers from a different angle.

If you want to reuse hashcode(s) from 'above' and derive new ones using your class' immutatable state, then a call to super will work. While this may/may not cascade all the way up to Object (i.e. some ancestor may not call super), it will allow you to derive hashcodes by reuse.

@Override
public int hashCode() {
    int ancestorHash = super.hashCode();
    // now derive new hash from ancestorHash plus immutable instance vars (id fields)
}

Bundler is launched from your app's root directory so it makes sure all needed gems are present to get your app working.If for some reason you no longer need a gem you'll have to run the

    gem uninstall gem_name 

as you stated above.So every time you run bundler it'll recheck dependencies

EDIT - 24.12.2014

I see that people keep coming to this question I decided to add a little something. The answer I gave was for the case when you maintain your gems global. Consider using a gem manager such as rbenv or rvm to keep sets of gems scoped to specific projects.

This means that no gems will be installed at a global level and therefore when you remove one from your project's Gemfile and rerun bundle then it, obviously, won't be loaded in your project. Then, you can run bundle clean (with the project dir) and it will remove from the system all those gems that were once installed from your Gemfile (in the same dir) but at this given time are no longer listed there.... long story short - it removes unused gems.

Suppose cellspcing / cellpadding / border-spacing property did not worked, you can use the code as follow.

<div class="form-group">
  <table width="100%" cellspacing="2px" style="border-spacing: 10px;">
    <tr>                        
      <td width="47%">
        <input type="submit" class="form-control btn btn-info" id="submit" name="Submit" />
      </td>

I've tried and got succeed while seperate the button by using table-width and make an empty td as 2 or 1% it doesn't return more different.

• Ok it's very easy actually to solve this...most of you who are presented with this problem probably don't even realize you don't have the full software yet installed :) I tried looking online with little success except some1 mentioned you need to look for those services running already. Forexample problem with filezilla you look in task manager for filezilla and you stop the process then you click the X in the xampp control pannel to install filezilla and then click run and it should start the service normally showing you a green lite with a check mark.

• Same goes for mysql issues.

• As for the apache problem, it usualy is a problem with the port being overtaken by skype or some other program, but you can find info how to solve that on the net easily :)

With netcat you can check whether a port is open like this:

nc my.example.com 80 < /dev/null

The return value of nc will be success if the TCP port was opened, and failure (typically the return code 1) if it could not make the TCP connection.

Some versions of nc will hang when you try this, because they do not close the sending half of their socket even after receiving the end-of-file from /dev/null. On my own Ubuntu laptop (18.04), the netcat-openbsd version of netcat that I have installed offers a workaround: the -N option is necessary to get an immediate result:

nc -N my.example.com 80 < /dev/null

There's no (safe) way to pause execution. You can, however, do something like this using setTimeout:

function writeNext(i)
{
    document.write(i);

    if(i == 5)
        return;

    setTimeout(function()
    {
        writeNext(i + 1);

    }, 2000);
}

writeNext(1);

In Python, you can't just embed arbitrary Python expressions into literal strings and have it substitute the value of the string. You need to either:

sys.stderr.write("Usage: " + sys.argv[0])

or

sys.stderr.write("Usage: %s" % sys.argv[0])

Also, you may want to consider using the following syntax of print (for Python earlier than 3.x):

print >>sys.stderr, "Usage:", sys.argv[0]

Using print arguably makes the code easier to read. Python automatically adds a space between arguments to the print statement, so there will be one space after the colon in the above example.

In Python 3.x, you would use the print function:

print("Usage:", sys.argv[0], file=sys.stderr)

Finally, in Python 2.6 and later you can use .format:

print >>sys.stderr, "Usage: {0}".format(sys.argv[0])

This should work in pretty much any browser...

function getByClass (className, parent) {
  parent || (parent=document);
  var descendants=parent.getElementsByTagName('*'), i=-1, e, result=[];
  while (e=descendants[++i]) {
    ((' '+(e['class']||e.className)+' ').indexOf(' '+className+' ') > -1) && result.push(e);
  }
  return result;
}

You should be able to use it like this:

function replaceInClass (className, content) {
  var nodes = getByClass(className), i=-1, node;
  while (node=nodes[++i]) node.innerHTML = content;
}

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). The default bundle is named curl-ca-bundle.crt; you can specify an alternate file using the --cacert option.

If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL).

If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

for example

curl --insecure http://........

if 'name' in mydict:

is the preferred, pythonic version. Use of has_key() is discouraged, and this method has been removed in Python 3.

It looks like ReflectionClass is a pretty productive option.

class MyClass {
    public function test() {
        // 'MyClass'
        return (new \ReflectionClass($this))->getShortName();
    }
}

For those wanting to create a dynamic class just properties (i.e. POCO), and create a list of this class. Using the code provided later, this will create a dynamic class and create a list of this.

var properties = new List<DynamicTypeProperty>()
{
    new DynamicTypeProperty("doubleProperty", typeof(double)),
    new DynamicTypeProperty("stringProperty", typeof(string))
};

// create the new type
var dynamicType = DynamicType.CreateDynamicType(properties);
// create a list of the new type
var dynamicList = DynamicType.CreateDynamicList(dynamicType);

// get an action that will add to the list
var addAction = DynamicType.GetAddAction(dynamicList);

// call the action, with an object[] containing parameters in exact order added
addAction.Invoke(new object[] {1.1, "item1"});
addAction.Invoke(new object[] {2.1, "item2"});
addAction.Invoke(new object[] {3.1, "item3"});

Here are the classes that the previous code uses.

Move to the root of your App then execute the following command,

react-native -v

In my case, it is something like below,

MacBook-Pro:~ admin$ cd projects/

MacBook-Pro:projects admin$ cd ReactNative/

MacBook-Pro:ReactNative admin$ cd src/

MacBook-Pro:src admin$ cd Apps/

MacBook-Pro:Apps admin$ cd CabBookingApp/

MacBook-Pro:CabBookingApp admin$ ls
MyComponents        __tests__       app.json        index.android.js    
ios         package.json
MyStyles        android         img         index.ios.js        
node_modules

Finally,

MacBook-Pro:CabBookingApp admin$ react-native -v
react-native-cli: 2.0.1
react-native: 0.44.0

Here's a really simple example that might get you started:

$(document).ready(function() {
    var $dragging = null;

    $(document.body).on("mousemove", function(e) {
        if ($dragging) {
            $dragging.offset({
                top: e.pageY,
                left: e.pageX
            });
        }
    });


    $(document.body).on("mousedown", "div", function (e) {
        $dragging = $(e.target);
    });

    $(document.body).on("mouseup", function (e) {
        $dragging = null;
    });
});

Example: http://jsfiddle.net/Jge9z/

I understand that I shall use the mouse position relative to the container div (in which the div shall be dragged) and that I shall set the divs offset relative to those values.

Not so sure about that. It seems to me that in drag and drop you'd always want to use the offset of the elements relative to the document.

If you mean you want to constrain the dragging to a particular area, that's a more complicated issue (but still doable).

What about this (a bit late):

def remove_prefix(s, prefix):
    return s[len(prefix):] if s.startswith(prefix) else s

Probably, not the cleanest solution, but it is definitely simpler than removing one-by-one:

document.getElementById("DropList").innerHTML = "";

I am using this solution in case to find out that my app is running on debug version.

if (BuildConfig.BUILD_TYPE.equals("debug")){
   //Do something
}

The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.

The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :

float()

And for more details you can visit this page.

getClass().getProtectionDomain().getCodeSource().getLocation();

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

CROSS APPLY to the rescue:

SELECT Orders.OrderNumber, topline.Quantity, topline.Description
FROM Orders
cross apply
(
    select top 1 Description,Quantity
    from LineItems 
    where Orders.OrderID = LineItems.OrderID
)topline

You can also add the order by of your choice.

To compare values you can use a comparing method-

function naturalSorter(as, bs){
    var a, b, a1, b1, i= 0, n, L,
    rx=/(\.\d+)|(\d+(\.\d+)?)|([^\d.]+)|(\.\D+)|(\.$)/g;
    if(as=== bs) return 0;
    a= as.toLowerCase().match(rx);
    b= bs.toLowerCase().match(rx);
    L= a.length;
    while(i<L){
        if(!b[i]) return 1;
        a1= a[i],
        b1= b[i++];
        if(a1!== b1){
            n= a1-b1;
            if(!isNaN(n)) return n;
            return a1>b1? 1:-1;
        }
    }
    return b[i]? -1:0;
}

But for speed in sorting an array, rig the array before sorting, so you only have to do lower case conversions and the regular expression once instead of in every step through the sort.

function naturalSort(ar, index){
    var L= ar.length, i, who, next, 
    isi= typeof index== 'number', 
    rx=  /(\.\d+)|(\d+(\.\d+)?)|([^\d.]+)|(\.(\D+|$))/g;
    function nSort(aa, bb){
        var a= aa[0], b= bb[0], a1, b1, i= 0, n, L= a.length;
        while(i<L){
            if(!b[i]) return 1;
            a1= a[i];
            b1= b[i++];
            if(a1!== b1){
                n= a1-b1;
                if(!isNaN(n)) return n;
                return a1>b1? 1: -1;
            }
        }
        return b[i]!= undefined? -1: 0;
    }
    for(i= 0; i<L; i++){
        who= ar[i];
        next= isi? ar[i][index] || '': who;
        ar[i]= [String(next).toLowerCase().match(rx), who];
    }
    ar.sort(nSort);
    for(i= 0; i<L; i++){
        ar[i]= ar[i][1];
    }
}

As a partial answer: mysql -N -B -e "select people, places from things"

-N tells it not to print column headers. -B is "batch mode", and uses tabs to separate fields.

If tab separated values won't suffice, see this Stackoverflow Q&A.

You can read a CSV file with headers into a NumPy structured array with np.genfromtxt. For example:

import numpy as np

csv_fname = 'file.csv'
with open(csv_fname, 'w') as fp:
    fp.write("""\
"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291113113366E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12
""")

# Read the CSV file into a Numpy record array
r = np.genfromtxt(csv_fname, delimiter=',', names=True, case_sensitive=True)
print(repr(r))

which looks like this:

array([(611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111196e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111311e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29112065e+12)],
      dtype=[('A', '<f8'), ('B', '<f8'), ('C', '<f8'), ('D', '<f8'), ('E', '<f8'), ('F', '<f8'), ('timestamp', '<f8')])

You can access a named column like this r['E']:

array([1715.37476, 1715.37476, 1715.37476])

Note: this answer previously used np.recfromcsv to read the data into a NumPy record array. While there was nothing wrong with that method, structured arrays are generally better than record arrays for speed and compatibility.

Without having a href, the click will reload the current page, so you need something like this:

<a href="#" onclick="f1()">jhhghj</a>

Or prevent the scroll like this:

<a href="#" onclick="f1(); return false;">jhhghj</a>

Or return false in your f1 function and:

<a href="#" onclick="return f1();">jhhghj</a>

....or, the unobtrusive way:

<a href="#" id="abc">jhg</a>
<a href="#" id="myLink">jhhghj</a>

<script type="text/javascript">
  document.getElementById("myLink").onclick = function() {
    document.getElementById("abc").href="xyz.php"; 
    return false;
  };
</script>

Update to a specific revision:

svn up -r1234 file

You can use java's InetAddress class for this purpose.

InetAddress IP=InetAddress.getLocalHost();
System.out.println("IP of my system is := "+IP.getHostAddress());

Output for my system = IP of my system is := 10.100.98.228

getHostAddress() returns

Returns the IP address string in textual presentation.

OR you can also do

InetAddress IP=InetAddress.getLocalHost();
System.out.println(IP.toString());

Output = IP of my system is := RanRag-PC/10.100.98.228

Based on the answer that @Mukund Kumar gave here's a version that passes the event argument to the anonymous function:

<a href="#" onClick="(function(e){
    console.log(e);
    alert('Hey i am calling');
    return false;
})(arguments[0]);return false;">click here</a>

The old version of jQuery Cookie has been deprecated, so if you're getting the error:

$.cookie is not a function

you should upgrade to the new version.

The API for the new version is also different - rather than using

$.cookie("yourCookieName");

you should use

Cookies.get("yourCookieName");

Add this annotation to your method

@RequestMapping(value = "/getString", method = RequestMethod.GET, produces = "application/json")

Tuple classes allow developers to be 'quick and lazy' by not defining a specific class for a specific use.

The property names are Item1, Item2, Item3 ..., which may not be meaningful in some cases or without documentation.

Tuple classes have strongly typed generic parameters. Still users of the Tuple classes may infer from the type of generic parameters.

With Java 8 we can handle this scenario without any external tools. javapackager tool coming with java 8 provides an option to create self contained application bundles:

-native type Generate self-contained application bundles (if possible). Use the -B option to provide arguments to the bundlers being used. If type is specified, then only a bundle of this type is created. If no type is specified, all is used.

The following values are valid for type:

-native type
Generate self-contained application bundles (if possible). Use the -B option to provide arguments to the bundlers being used. If type is specified, then only a bundle of this type is created. If no type is specified, all is used.

The following values are valid for type:

all: Runs all of the installers for the platform on which it is running, and creates a disk image for the application. This value is used if type is not specified.
installer: Runs all of the installers for the platform on which it is running.
image: Creates a disk image for the application. On OS X, the image is the .app file. On Linux, the image is the directory that gets installed.
dmg: Generates a DMG file for OS X.
pkg: Generates a .pkg package for OS X.
mac.appStore: Generates a package for the Mac App Store.
rpm: Generates an RPM package for Linux.
deb: Generates a Debian package for Linux.

In case of windows refer the following doc we can create msi or exe as needed.

exe: Generates a Windows .exe package.
msi: Generates a Windows Installer package.

There is a big difference if you are using jQuery. jQuery is aware of more events on inputs than it does on buttons. On buttons, jQuery is only aware of 'click' events. On inputs, jQuery is aware of 'click', 'focus', and 'blur' events.

You could always bind events to your buttons as needed, but just be aware that the events that jQuery automatically is aware of are different. For example, if you created a function that was executed whenever there was a 'focusin' event on your page, an input would trigger the function but a button would not.

echo -ne '\n' | <yourfinecommandhere>

or taking advantage of the implicit newline that echo generates (thanks Marcin)

echo | <yourfinecommandhere>

Now we can simply use the --sk option:

--sk, --skip-keypress Don't wait for a keypress after each test

i.e. sudo rkhunter --sk --checkall

The context lets you provide arguments at call-time, allowing easy customization of generic pre-built helper functions.

some examples:

// stock footage:
function addTo(x){ "use strict"; return x + this; }
function pluck(x){ "use strict"; return x[this]; }
function lt(x){ "use strict"; return x < this; }

// production:
var r = [1,2,3,4,5,6,7,8,9];
var words = "a man a plan a canal panama".split(" ");

// filtering numbers:
_.filter(r, lt, 5); // elements less than 5
_.filter(r, lt, 3); // elements less than 3

// add 100 to the elements:
_.map(r, addTo, 100);

// encode eggy peggy:
_.map(words, addTo, "egg").join(" ");

// get length of words:
_.map(words, pluck, "length"); 

// find words starting with "e" or sooner:
_.filter(words, lt, "e"); 

// find all words with 3 or more chars:
_.filter(words, pluck, 2); 

Even from the limited examples, you can see how powerful an "extra argument" can be for creating re-usable code. Instead of making a different callback function for each situation, you can usually adapt a low-level helper. The goal is to have your custom logic bundling a verb and two nouns, with minimal boilerplate.

Admittedly, arrow functions have eliminated a lot of the "code golf" advantages of generic pure functions, but the semantic and consistency advantages remain.

I always add "use strict" to helpers to provide native [].map() compatibility when passing primitives. Otherwise, they are coerced into objects, which usually still works, but it's faster and safer to be type-specific.

You may also use the jQuery context parameter. Link to docs

Selector Context

By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function

Therefore you could also have:

success: function(data){
    var oneval = $('#one',data).text();
    var subval = $('#sub',data).text();
}

Swift 4.2 / Xcode 10.1:

Just uncheck behavior Enabled in your storyboard -> attributes inspector.

If you don't know the name of params and want to work with them all, you can use request.GET.keys() or dict(request.GET) functions
