The linked docs give the following example:

   cursor.execute ("""
         UPDATE animal SET name = %s
         WHERE name = %s
       """, ("snake", "turtle"))
   print "Number of rows updated: %d" % cursor.rowcount

So you just need to adapt this to your own code - example:

cursor.execute ("""
            INSERT INTO Songs (SongName, SongArtist, SongAlbum, SongGenre, SongLength, SongLocation)
            VALUES
                (%s, %s, %s, %s, %s, %s)

        """, (var1, var2, var3, var4, var5, var6))

(If SongLength is numeric, you may need to use %d instead of %s).

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

Since we are doing this one to death - you don't have to specify a year:

select * from demo
where  somedate between to_date('01/01 00:00:00', 'DD/MM HH24:MI:SS')
                and     to_date('31/12 23:59:59', 'DD/MM HH24:MI:SS');

However the accepted answer by FerranB makes more sense if you want to specify all date values that fall within the current year.

Better way:

encodeURIComponent escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )

To avoid unexpected requests to the server, you should call encodeURIComponent on any user-entered parameters that will be passed as part of a URI. For example, a user could type "Thyme &time=again" for a variable comment. Not using encodeURIComponent on this variable will give comment=Thyme%20&time=again. Note that the ampersand and the equal sign mark a new key and value pair. So instead of having a POST comment key equal to "Thyme &time=again", you have two POST keys, one equal to "Thyme " and another (time) equal to again.

For application/x-www-form-urlencoded (POST), per http://www.w3.org/TR/html401/interac...m-content-type, spaces are to be replaced by '+', so one may wish to follow a encodeURIComponent replacement with an additional replacement of "%20" with "+".

If one wishes to be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:

function fixedEncodeURIComponent (str) {
  return encodeURIComponent(str).replace(/[!'()]/g, escape).replace(/\*/g, "%2A");
}

@bku_drytt's solution didn't do it for me.

I solved it by additionally changing every occurence of 14.0 to 12.0 and v140 to v120 manually in the .vcxproj files.

Then it compiled!

If you just want to check if a string is all digits (without being within a particular number range) you can use:

string test = "123";
bool allDigits = test.All(char.IsDigit);

Make the sql mode non strict

if using laravel go to config->database, the go to mysql settings and make the strict mode false

As mentioned by nux and micheg79 a node is left behind in the DOM after the dialog closes.

This can also be cleaned up simply by adding:

$(this).dialog('destroy').remove();

to the close method of the dialog. Example adding this line to eidylon's answer:

function jqAlert(outputMsg, titleMsg, onCloseCallback) {
    if (!titleMsg)
        titleMsg = 'Alert';

    if (!outputMsg)
        outputMsg = 'No Message to Display.';

    $("<div></div>").html(outputMsg).dialog({
        title: titleMsg,
        resizable: false,
        modal: true,
        buttons: {
            "OK": function () {
                $(this).dialog("close");
            }
        },
        close: function() { onCloseCallback();
                           /* Cleanup node(s) from DOM */
                           $(this).dialog('destroy').remove();
                          }
    });
}

EDIT: I had problems getting callback function to run and found that I had to add parentheses () to onCloseCallback to actually trigger the callback. This helped me understand why: In JavaScript, does it make a difference if I call a function with parentheses?

I'm late on this, but I was having this issue and what I've learned was that it was an error on my PHP code (in my case the syntax of a select to the db). Usually this error 500 is something to do using syntax - in my experience. In other word: "peopleware" issue! :D

You can also press = while less is open to just display (at the bottom of the screen) information about the current screen, including line numbers, with format:

myfile.txt lines 20530-20585/1816468 byte 1098945/116097872 1%  (press RETURN)

So here for example, the screen was currently showing lines 20530-20585, and the files has a total of 1816468 lines.

To expand on Craig Glennie's answer:

in Python 3.6.1 on MacOs Sierra

Entering this in the bash terminal solved the problem:

Since other questions are being redirected to this one which ask about asanyarray or other array creation routines, it's probably worth having a brief summary of what each of them does.

The differences are mainly about when to return the input unchanged, as opposed to making a new array as a copy.

array offers a wide variety of options (most of the other functions are thin wrappers around it), including flags to determine when to copy. A full explanation would take just as long as the docs (see Array Creation, but briefly, here are some examples:

Assume a is an ndarray, and m is a matrix, and they both have a dtype of float32:

• np.array(a) and np.array(m) will copy both, because that's the default behavior.
• np.array(a, copy=False) and np.array(m, copy=False) will copy m but not a, because m is not an ndarray.
• np.array(a, copy=False, subok=True) and np.array(m, copy=False, subok=True) will copy neither, because m is a matrix, which is a subclass of ndarray.
• np.array(a, dtype=int, copy=False, subok=True) will copy both, because the dtype is not compatible.

Most of the other functions are thin wrappers around array that control when copying happens:

• asarray: The input will be returned uncopied iff it's a compatible ndarray (copy=False).
• asanyarray: The input will be returned uncopied iff it's a compatible ndarray or subclass like matrix (copy=False, subok=True).
• ascontiguousarray: The input will be returned uncopied iff it's a compatible ndarray in contiguous C order (copy=False, order='C').
• asfortranarray: The input will be returned uncopied iff it's a compatible ndarray in contiguous Fortran order (copy=False, order='F').
• require: The input will be returned uncopied iff it's compatible with the specified requirements string.
• copy: The input is always copied.
• fromiter: The input is treated as an iterable (so, e.g., you can construct an array from an iterator's elements, instead of an object array with the iterator); always copied.

There are also convenience functions, like asarray_chkfinite (same copying rules as asarray, but raises ValueError if there are any nan or inf values), and constructors for subclasses like matrix or for special cases like record arrays, and of course the actual ndarray constructor (which lets you create an array directly out of strides over a buffer).

Working jsFiddle Demo

When you are working with fixed or absolute values, it's good idea to set top or bottom and left or right (or combination of them) properties.

Also don't set the height of main element (let browser set the height of it with setting top and bottom properties).

.header{
    position: fixed;
    background-color: #f00;
    height: 100px;
    top: 0;
    left: 0;
    right: 0;
}
.main{
    background-color: #ff0;
    position: fixed;
    bottom: 120px;
    left: 0;
    right: 0;
    top: 100px;
    overflow: auto;
}
.footer{
    position: fixed;
    bottom: 0;
    background-color: #f0f;
    height: 120px;
    bottom: 0;
    left: 0;
    right: 0;
}

I would like to recommend flask-empty at GitHub.

It provides an easy way to understand Blueprints, multiple views and extensions.

The stack pointer stores the address of the most recent entry that was pushed onto the stack.

To push a value onto the stack, the stack pointer is incremented to point to the next physical memory address, and the new value is copied to that address in memory.

To pop a value from the stack, the value is copied from the address of the stack pointer, and the stack pointer is decremented, pointing it to the next available item in the stack.

The most typical use of a hardware stack is to store the return address of a subroutine call. When the subroutine is finished executing, the return address is popped off the top of the stack and placed in the Program Counter register, causing the processor to resume execution at the next instruction following the call to the subroutine.

http://en.wikipedia.org/wiki/Stack_%28data_structure%29#Hardware_stacks

I think it's because you didn't specify the width and height for the item.

If you only want to have 2 images in a row, you can try something like this instead of using flex:

item: {
    width: '50%',
    height: '100%',
    overflow: 'hidden',
    alignItems: 'center',
    backgroundColor: 'orange',
    position: 'relative',
    margin: 10,
},

This works for me, hope it helps.

In Flask you just need to write:

curs = conn.cursor()
curs.execute("ROLLBACK")
conn.commit()

P.S. Documentation goes here https://www.postgresql.org/docs/9.4/static/sql-rollback.html

In C++11's std::vector you can instantiate elements in-place using emplace_back:

  std::vector<Car> mycars;

  for (int i = 0; i < userInput; ++i)
  {
      mycars.emplace_back(i + 1); // pass in Car() constructor arguments
  }

Voila!

Car() default constructor never invoked.

Deletion will happen automatically when mycars goes out of scope.

You might find your code is more maintainable if you keep all your styles, etc. in CSS and just set / unset class names in JavaScript.

Your CSS would obviously be something like:

.highlight {
    background:#ff00aa;
}

Then in JavaScript:

element.className = element.className === 'highlight' ? '' : 'highlight';

There are lots of ways to describe the table in PostgreSQL

The simple answer is

    > /d <table_name> -- OR

    > /d+ <table_name>

Usage

If you are in Postgres shell [psql] and you need to describe the tables

You can achieve this by Query also [As lots of friends has posted the correct ways]

There are lots of details regarding the Schema are available in Postgres's default table names information_schema. You can directly use it to retrieve the information of any of table using a simple SQL statement.

Easy query

    SELECT
      *
    FROM
      information_schema.columns
    WHERE
      table_schema = 'your_schema' AND
      table_name   = 'your_table';

Medium query

  SELECT
      a.attname AS Field,
      t.typname || '(' || a.atttypmod || ')' AS Type,
      CASE WHEN a.attnotnull = 't' THEN 'YES' ELSE 'NO' END AS Null,
      CASE WHEN r.contype = 'p' THEN 'PRI' ELSE '' END AS Key,
      (SELECT substring(pg_catalog.pg_get_expr(d.adbin, d.adrelid), '\'(.*)\'')
              FROM
                      pg_catalog.pg_attrdef d
              WHERE
                      d.adrelid = a.attrelid
                      AND d.adnum = a.attnum
                      AND a.atthasdef) AS Default,
      '' as Extras
  FROM
        pg_class c 
        JOIN pg_attribute a ON a.attrelid = c.oid
        JOIN pg_type t ON a.atttypid = t.oid
        LEFT JOIN pg_catalog.pg_constraint r ON c.oid = r.conrelid 
                AND r.conname = a.attname
  WHERE
        c.relname = 'tablename'
        AND a.attnum > 0

  ORDER BY a.attnum

You just need to replace the tablename.

Hard query

  SELECT  
      f.attnum AS number,  
      f.attname AS name,  
      f.attnum,  
      f.attnotnull AS notnull,  
      pg_catalog.format_type(f.atttypid,f.atttypmod) AS type,  
      CASE  
          WHEN p.contype = 'p' THEN 't'  
          ELSE 'f'  
      END AS primarykey,  
      CASE  
          WHEN p.contype = 'u' THEN 't'  
          ELSE 'f'
      END AS uniquekey,
      CASE
          WHEN p.contype = 'f' THEN g.relname
      END AS foreignkey,
      CASE
          WHEN p.contype = 'f' THEN p.confkey
      END AS foreignkey_fieldnum,
      CASE
          WHEN p.contype = 'f' THEN g.relname
      END AS foreignkey,
      CASE
          WHEN p.contype = 'f' THEN p.conkey
      END AS foreignkey_connnum,
      CASE
          WHEN f.atthasdef = 't' THEN d.adsrc
      END AS default
  FROM pg_attribute f  
      JOIN pg_class c ON c.oid = f.attrelid  
      JOIN pg_type t ON t.oid = f.atttypid  
      LEFT JOIN pg_attrdef d ON d.adrelid = c.oid AND d.adnum = f.attnum  
      LEFT JOIN pg_namespace n ON n.oid = c.relnamespace  
      LEFT JOIN pg_constraint p ON p.conrelid = c.oid AND f.attnum = ANY (p.conkey)  
      LEFT JOIN pg_class AS g ON p.confrelid = g.oid  
  WHERE c.relkind = 'r'::char  
      AND n.nspname = 'schema'  -- Replace with Schema name  
      AND c.relname = 'tablename'  -- Replace with table name  
      AND f.attnum > 0 ORDER BY number;

You can choose any of the above ways, to describe the table.

Any of you can edit these answers to improve the ways. I'm open to merge your changes. :)

In Excel 2007 onwards, you can use the much simpler code using a more precise reference:

dim pvt as PivotTable
dim pvtField as PivotField

set pvt = ActiveSheet.PivotTables("PivotTable2")
set pvtField = pvt.PivotFields("SavedFamilyCode")

pvtField.PivotFilters.Add xlCaptionEquals, Value1:= "K123223"

I have faced this issue many times. The root problem being

1. The target sdk version is not selected in the project settings

or

1. The file default.properties (next to manifest.xml) is either missing or min sdk level not set.

Check those two and do a clean build as suggested in earlier options it should work fine.

Check for errors in "Problems" or "Console" tab.

Lastly : Do you have / eclipse has write permissions to the project folder? (also less probable one is disk space)

Take a look at

• Itty (blog post)
• Bottle
• web.py
• juno

You can use this

 File dir=new File(TestMain.class.getClassLoader().getResource("filename").getPath());

pandas >= 0.24

Deprecate your usage of .values in favour of these methods!

From v0.24.0 onwards, we will have two brand spanking new, preferred methods for obtaining NumPy arrays from Index, Series, and DataFrame objects: they are to_numpy(), and .array. Regarding usage, the docs mention:

We haven’t removed or deprecated Series.values or DataFrame.values, but we highly recommend and using .array or .to_numpy() instead.

See this section of the v0.24.0 release notes for more information.

to_numpy() Method

df.index.to_numpy()
# array(['a', 'b'], dtype=object)

df['A'].to_numpy()
#  array([1, 4])

By default, a view is returned. Any modifications made will affect the original.

v = df.index.to_numpy()
v[0] = -1

df
    A  B
-1  1  2
b   4  5

If you need a copy instead, use to_numpy(copy=True);

v = df.index.to_numpy(copy=True)
v[-1] = -123

df
   A  B
a  1  2
b  4  5

Note that this function also works for DataFrames (while .array does not).

array Attribute
This attribute returns an ExtensionArray object that backs the Index/Series.

pd.__version__
# '0.24.0rc1'

# Setup.
df = pd.DataFrame([[1, 2], [4, 5]], columns=['A', 'B'], index=['a', 'b'])
df

   A  B
a  1  2
b  4  5

df.index.array    
# <PandasArray>
# ['a', 'b']
# Length: 2, dtype: object

df['A'].array
# <PandasArray>
# [1, 4]
# Length: 2, dtype: int64

From here, it is possible to get a list using list:

list(df.index.array)
# ['a', 'b']

list(df['A'].array)
# [1, 4]

or, just directly call .tolist():

df.index.tolist()
# ['a', 'b']

df['A'].tolist()
# [1, 4]

Regarding what is returned, the docs mention,

For Series and Indexes backed by normal NumPy arrays, Series.array will return a new arrays.PandasArray, which is a thin (no-copy) wrapper around a numpy.ndarray. arrays.PandasArray isn’t especially useful on its own, but it does provide the same interface as any extension array defined in pandas or by a third-party library.

So, to summarise, .array will return either

1. The existing ExtensionArray backing the Index/Series, or
2. If there is a NumPy array backing the series, a new ExtensionArray object is created as a thin wrapper over the underlying array.

Rationale for adding TWO new methods
These functions were added as a result of discussions under two GitHub issues GH19954 and GH23623.

Specifically, the docs mention the rationale:

[...] with .values it was unclear whether the returned value would be the actual array, some transformation of it, or one of pandas custom arrays (like Categorical). For example, with PeriodIndex, .values generates a new ndarray of period objects each time. [...]

These two functions aim to improve the consistency of the API, which is a major step in the right direction.

Lastly, .values will not be deprecated in the current version, but I expect this may happen at some point in the future, so I would urge users to migrate towards the newer API, as soon as you can.

If you are programming a game perhaps you would like to change the background color and use only spaces? For example:

print " "+ "\033[01;41m" + " " +"\033[01;46m"  + "  " + "\033[01;42m"

Simplest of all solutions:

Add the below code in CSS:

.tableClassName tbody {
  display: block;
  max-height: 200px;
  overflow-y: scroll;
}

.tableClassName thead, .tableClassName tbody tr {
  display: table;
  width: 100%;
  table-layout: fixed;
}
.tableClassName thead {
  width: calc( 100% - 1.1em );
}

1.1 em is the average width of the scroll bar, please modify this if needed.

Most probably deleting service fails because

protected override void OnStop()

throw error when stopping a service. wrapping things inside a try catch will prevent mark for deletion error

protected override void OnStop()
{
            try
            {
                //things to do
            }
            catch (Exception)
            {
            }

}

1. First, launch your Safari browser from the Home screen and go to the webpage that you want to view full screen.

2. After locating the webpage, tap on the arrow icon at the top of your screen.

3. In the drop-down menu, tap on the Add to Home Screen option.

4. The Add to Home window should be displayed. You can customize the description that will appear as a title on the home screen of your iPad. When you are done, tap on the Add button.

5. A new icon should now appear on your home screen. Tapping on the icon will open the webpage in the fullscreen mode.

Note: The icon on your iPad home screen only opens the bookmarked page in the fullscreen mode. The next page you visit will be contain the Safari address and title bars. This way of playing your webpage or HTML5 presentation in the fullscreen mode works if the source code of the webpage contains the following tag:

<meta name="apple-mobile-web-app-capable" content="yes">

You can add this tag to your webpage using a third-party tool, for example iWeb SEO Tool or any other you like. Please note that you need to add the tag first, refresh the page and then add a bookmark to your home screen.

If you get a model instance from the database, then calling the save method will always update that instance. For example:

t = TemperatureData.objects.get(id=1)
t.value = 999  # change field
t.save() # this will update only

If your goal is prevent any INSERTs, then you can override the save method, test if the primary key exists and raise an exception. See the following for more detail:

• How Django knows to UPDATE vs. INSERT

I like more another approach described in a similar question: https://stackoverflow.com/a/11885521/2215679

This approach is better especially in case if you need to show more than one field in SELECT. To avoid Error Code: 1241. Operand should contain 1 column(s) or double sub-select for each column.

For your situation the Query should looks like:

SELECT
 c.id,
 c.title,
 p.id AS product_id,
 p.title AS product_title
FROM categories AS c
JOIN products AS p ON
 p.id = (                                 --- the PRIMARY KEY
  SELECT p1.id FROM products AS p1
  WHERE c.id=p1.category_id
  ORDER BY p1.id LIMIT 1
 )

Goes to the right and can be used the same way for the left

.yourComponent
{
   float: right;
   bottom: 0;
}

This article describes how to get information about locked MySQL resources. mysqladmin debug might also be of some use.

I believe app:itemBackground expects a drawable. So follow the steps below :

Make a drawable file highlight_color.xml with following contents :

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
     <solid android:color="YOUR HIGHLIGHT COLOR"/>
</shape>

Make another drawable file nav_item_drawable.xml with following contents:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/highlight_color" android:state_checked="true"/>
</selector>

Finally add app:itemBackground tag in the NavView :

<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:itemIconTint="@color/black"
app:itemTextColor="@color/primary_text"
app:itemBackground="@drawable/nav_item_drawable"
app:menu="@menu/menu_drawer">

here the highlight_color.xml file defines a solid color drawable for the background. Later this color drawable is assigned to nav_item_drawable.xml selector.

This worked for me. Hopefully this will help.

********************************************** UPDATED **********************************************

Though the above mentioned answer gives you fine control over some properties, but the way I am about to describe feels more SOLID and is a bit COOLER.

So what you can do is, you can define a ThemeOverlay in the styles.xml for the NavigationView like this :

    <style name="ThemeOverlay.AppCompat.navTheme">

        <!-- Color of text and icon when SELECTED -->
        <item name="colorPrimary">@color/color_of_your_choice</item> 

        <!-- Background color when SELECTED -->
        <item name="colorControlHighlight">@color/color_of_your_choice</item> 

    </style>

now apply this ThemeOverlay to app:theme attribute of NavigationView, like this:

<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:theme="@style/ThemeOverlay.AppCompat.navTheme"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/menu_drawer">

I hope this will help.

HashMaps don't keep your key/value pairs in a specific order. They are ordered based on the hash that each key's returns from its Object.hashCode() method. You can however iterate over the set of key/value pairs using an iterator with:

for (String key : hashmap.keySet()) 
{
    for (list : hashmap.get(key))
    {
        //list.toString()
    }
}

While an older question that has been answered by many I believe a succinct method, not so different from the others posted, is to use a minor macro to help ease the duplication of class declarations.

// abstract.h

// Simply define the types that each concrete class will use
#define IMPL_RENDER() \
    void render(int a, char *b) override { render_internal<char>(a, b); }   \
    void render(int a, short *b) override { render_internal<short>(a, b); } \
    // ...

class Renderable
{
public:
    // Then, once for each on the abstract
    virtual void render(int a, char *a) = 0;
    virtual void render(int a, short *b) = 0;
    // ...
};

So now, to implement our subclass:

class Box : public Renderable
{
public:
    IMPL_RENDER() // Builds the functions we want

private:
    template<typename T>
    void render_internal(int a, T *b); // One spot for our logic
};

The benefit here is that, when adding a newly supported type, it can all be done from the abstract header and forego possibly rectifying it in multiple source/header files.

I use JQuery to perform a simple AJAX call to a dummy HTTP Handler that does nothing but keeping my Session alive:

function setHeartbeat() {
    setTimeout("heartbeat()", 5*60*1000); // every 5 min
}

function heartbeat() {
    $.get(
        "/SessionHeartbeat.ashx",
        null,
        function(data) {
            //$("#heartbeat").show().fadeOut(1000); // just a little "red flash" in the corner :)
            setHeartbeat();
        },
        "json"
    );
}

Session handler can be as simple as:

public class SessionHeartbeatHttpHandler : IHttpHandler, IRequiresSessionState
{
    public bool IsReusable { get { return false; } }

    public void ProcessRequest(HttpContext context)
    {
        context.Session["Heartbeat"] = DateTime.Now;
    }
}

The key is to add IRequiresSessionState, otherwise Session won't be available (= null). The handler can of course also return a JSON serialized object if some data should be returned to the calling JavaScript.

Made available through web.config:

<httpHandlers>
    <add verb="GET,HEAD" path="SessionHeartbeat.ashx" validate="false" type="SessionHeartbeatHttpHandler"/>
</httpHandlers>

I liked so much of this example, that I want to improve with the HTML/CSS and the beat part

change this

//$("#heartbeat").show().fadeOut(1000); // just a little "red flash" in the corner :)

into

beatHeart(2); // just a little "red flash" in the corner :)

and add

// beat the heart 
// 'times' (int): nr of times to beat
function beatHeart(times) {
    var interval = setInterval(function () {
        $(".heartbeat").fadeIn(500, function () {
            $(".heartbeat").fadeOut(500);
        });
    }, 1000); // beat every second

    // after n times, let's clear the interval (adding 100ms of safe gap)
    setTimeout(function () { clearInterval(interval); }, (1000 * times) + 100);
}

HTML and CSS

<div class="heartbeat">&hearts;</div>

/* HEARBEAT */
.heartbeat {
    position: absolute;
    display: none;
    margin: 5px;
    color: red;
    right: 0;
    top: 0;
}

here is a live example for only the beating part: http://jsbin.com/ibagob/1/

if you want to go via SSMS on the object explorer window, right click on the object you want to drop, do view dependencies.

In my case, the problem was caused by some Response.Write commands at Master Page of the website (code behind). They were there only for debugging purposes (that's not the best way, I know)...

var myVar = $("#start").find('myClass').val();

needs to be

var myVar = $("#start").find('.myClass').val();

Remember the CSS selector rules require "." if selecting by class name. The absence of "." is interpreted to mean searching for <myclass></myclass>.

you can also add host as well with same command like :

php artisan serve --host=172.10.29.100 --port=8080

try this

$("#inp").focus(function(){$("#sel").attr('disabled','true');});

$("#inp").blur(function(){$("#sel").removeAttr('disabled');});

vice versa for the select also.

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

str() is used for creating output for end user while repr() is used for debuggin development.And it's represent the official of object.

Example:

>>> import datetime
>>> today = datetime.datetime.now()
>>> str(today)
'2018-04-08 18:00:15.178404'
>>> repr(today)
'datetime.datetime(2018, 4, 8, 18, 3, 21, 167886)'

From output we see that repr() shows the official representation of date object.

What means about isKindOfClass in Apple Documentation

Be careful when using this method on objects represented by a class cluster. Because of the nature of class clusters, the object you get back may not always be the type you expected. If you call a method that returns a class cluster, the exact type returned by the method is the best indicator of what you can do with that object. For example, if a method returns a pointer to an NSArray object, you should not use this method to see if the array is mutable, as shown in the following code:

// DO NOT DO THIS!
if ([myArray isKindOfClass:[NSMutableArray class]])
{
    // Modify the object
}

If you use such constructs in your code, you might think it is alright to modify an object that in reality should not be modified. Doing so might then create problems for other code that expected the object to remain unchanged.

I know this is late, but it does answer your original question.

I know the answer is quite late, but the best way to get rid of milliseconds is

var currentDateTime = DateTime.Now.ToString("s");

Try printing the value of the variable, it will show the date time, without milliseconds.

ClusterIP: Services are reachable by pods/services in the Cluster
If I make a service called myservice in the default namespace of type: ClusterIP then the following predictable static DNS address for the service will be created:

myservice.default.svc.cluster.local (or just myservice.default, or by pods in the default namespace just "myservice" will work)

And that DNS name can only be resolved by pods and services inside the cluster.

NodePort: Services are reachable by clients on the same LAN/clients who can ping the K8s Host Nodes (and pods/services in the cluster) (Note for security your k8s host nodes should be on a private subnet, thus clients on the internet won't be able to reach this service)
If I make a service called mynodeportservice in the mynamespace namespace of type: NodePort on a 3 Node Kubernetes Cluster. Then a Service of type: ClusterIP will be created and it'll be reachable by clients inside the cluster at the following predictable static DNS address:

mynodeportservice.mynamespace.svc.cluster.local (or just mynodeportservice.mynamespace)

For each port that mynodeportservice listens on a nodeport in the range of 30000 - 32767 will be randomly chosen. So that External clients that are outside the cluster can hit that ClusterIP service that exists inside the cluster. Lets say that our 3 K8s host nodes have IPs 10.10.10.1, 10.10.10.2, 10.10.10.3, the Kubernetes service is listening on port 80, and the Nodeport picked at random was 31852.

A client that exists outside of the cluster could visit 10.10.10.1:31852, 10.10.10.2:31852, or 10.10.10.3:31852 (as NodePort is listened for by every Kubernetes Host Node) Kubeproxy will forward the request to mynodeportservice's port 80.

LoadBalancer: Services are reachable by everyone connected to the internet* (Common architecture is L4 LB is publicly accessible on the internet by putting it in a DMZ or giving it both a private and public IP and k8s host nodes are on a private subnet)
(Note: This is the only service type that doesn't work in 100% of Kubernetes implementations, like bare metal Kubernetes, it works when Kubernetes has cloud provider integrations.)

If you make mylbservice, then a L4 LB VM will be spawned (a cluster IP service, and a NodePort Service will be implicitly spawned as well). This time our NodePort is 30222. the idea is that the L4 LB will have a public IP of 1.2.3.4 and it will load balance and forward traffic to the 3 K8s host nodes that have private IP addresses. (10.10.10.1:30222, 10.10.10.2:30222, 10.10.10.3:30222) and then Kube Proxy will forward it to the service of type ClusterIP that exists inside the cluster.

You also asked: Does the NodePort service type still use the ClusterIP? Yes*
Or is the NodeIP actually the IP found when you run kubectl get nodes? Also Yes*

Lets draw a parrallel between Fundamentals:
A container is inside a pod. a pod is inside a replicaset. a replicaset is inside a deployment.
Well similarly:
A ClusterIP Service is part of a NodePort Service. A NodePort Service is Part of a Load Balancer Service.

In that diagram you showed, the Client would be a pod inside the cluster.

The C/A Browser forum sets what is and is not valid in a certificate, and what CA's should reject.

According to their Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates document, CAs must, since 2015, not issue certificats where the common name, or common alternate names fields contains a reserved IP or internal name, where reserved IP addresses are IPs that IANA has listed as reserved - which includes all NAT IPs - and internal names are any names that don't resolve on the public DNS.

Public IP addresses CAN be used (and the baseline requirements doc specifies what kinds of checks a CA must perform to ensure the applicant owns the IP).

If you ever wondered how to do it using the new BDD style of Mockito:

willThrow(new Exception()).given(mockedObject).methodReturningVoid(...));

And for future reference one may need to throw exception and then do nothing:

willThrow(new Exception()).willDoNothing().given(mockedObject).methodReturningVoid(...));

First you need to allocate an array of the combined length, then use arraycopy to fill it from both sources.

byte[] ciphertext = blah;
byte[] mac = blah;
byte[] out = new byte[ciphertext.length + mac.length];


System.arraycopy(ciphertext, 0, out, 0, ciphertext.length);
System.arraycopy(mac, 0, out, ciphertext.length, mac.length);

Let's assume you want to overwrite the same file:

import json

with open('data.json', 'r') as data_file:
    data = json.load(data_file)

for element in data:
    element.pop('hours', None)

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

dict.pop(<key>, not_found=None) is probably what you where looking for, if I understood your requirements. Because it will remove the hours key if present and will not fail if not present.

However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?

Now, if you really want to use del instead of pop, here is how you could make your code work:

import json

with open('data.json') as data_file:
    data = json.load(data_file)

for element in data:
    if 'hours' in element:
        del element['hours']

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.

I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.

with is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.

Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.

I hope it's clear enough...

SECOND EDIT

This time, it seems clear that you need to do this:

with open('dest_file.json', 'w') as dest_file:
    with open('source_file.json', 'r') as source_file:
        for line in source_file:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            dest_file.write(json.dumps(element))

You seem to be aware already, but I'll just restate it anyway; It's a bad sign, if you need to test protected methods. The aim of a unit test, is to test the interface of a class, and protected methods are implementation details. That said, there are cases where it makes sense. If you use inheritance, you can see a superclass as providing an interface for the subclass. So here, you would have to test the protected method (But never a private one). The solution to this, is to create a subclass for testing purpose, and use this to expose the methods. Eg.:

class Foo {
  protected function stuff() {
    // secret stuff, you want to test
  }
}

class SubFoo extends Foo {
  public function exposedStuff() {
    return $this->stuff();
  }
}

Note that you can always replace inheritance with composition. When testing code, it's usually a lot easier to deal with code that uses this pattern, so you may want to consider that option.

ntile from dplyr now does this but behaves weirdly with NA's.

I've used similar code in the following function that works in base R and does the equivalent of the cut2 solution above:

ntile_ <- function(x, n) {
    b <- x[!is.na(x)]
    q <- floor((n * (rank(b, ties.method = "first") - 1)/length(b)) + 1)
    d <- rep(NA, length(x))
    d[!is.na(x)] <- q
    return(d)
}

"Domain" is not a property of an LDAP object. It is more like the name of the database the object is stored in.

So you have to connect to the right database (in LDAP terms: "bind to the domain/directory server") in order to perform a search in that database.

Once you bound successfully, your query in it's current shape is all you need.

BTW: Choosing "ObjectCategory=Person" over "ObjectClass=user" was a good decision. In AD, the former is an "indexed property" with excellent performance, the latter is not indexed and a tad slower.

Call the toISOString() method:

var dt = new Date("30 July 2010 15:05 UTC");
document.write(dt.toISOString());

// Output:
//  2010-07-30T15:05:00.000Z

I created a simple IBDesignable. Use it however u like. Just make your UITextField confirm to this class.

    @IBInspectable var cornerRadius : CGFloat = 0{
        didSet{
            layer.cornerRadius = cornerRadius
            layer.masksToBounds = cornerRadius > 0
        }
    }

    @IBInspectable var borderWidth : CGFloat = 0 {
        didSet{
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var borderColor : UIColor? {
        didSet {
            layer.borderColor = borderColor?.cgColor
        }
    }

    @IBInspectable var bgColor : UIColor? {
        didSet {
            backgroundColor = bgColor
        }
    }

    @IBInspectable var leftImage : UIImage? {
        didSet {
            if let image = leftImage{
                leftViewMode = .always
                let imageView = UIImageView(frame: CGRect(x: 20, y: 0, width: 20, height: 20))
                imageView.image = image
                imageView.tintColor = tintColor
                let view = UIView(frame : CGRect(x: 0, y: 0, width: 25, height: 20))
                view.addSubview(imageView)
                leftView = view
            }else {
                leftViewMode = .never
            }

        }
    }

    @IBInspectable var placeholderColor : UIColor? {
        didSet {
            let rawString = attributedPlaceholder?.string != nil ? attributedPlaceholder!.string : ""
            let str = NSAttributedString(string: rawString, attributes: [NSForegroundColorAttributeName : placeholderColor!])
            attributedPlaceholder = str
        }
    }

    override func textRect(forBounds bounds: CGRect) -> CGRect {
        return bounds.insetBy(dx: 50, dy: 5)
    }

    override func editingRect(forBounds bounds: CGRect) -> CGRect {
        return bounds.insetBy(dx: 50, dy: 5)
    }

}

If your SQL Server version supports the function FORMAT you could do it like this:

select format(getdate(), 'yyyy-MM-dd HH:mm:ss.fff')

Try this:

 str = String.valueOf(a)+String.valueOf(b)+String.valueOf(c);

Output:

I think

DATEPART(dw,ads.date - 1) as weekday 

would work.

Use rgba!

.alpha60 {
    /* Fallback for web browsers that don't support RGBa */
    background-color: rgb(0, 0, 0);
    /* RGBa with 0.6 opacity */
    background-color: rgba(0, 0, 0, 0.6);
    /* For IE 5.5 - 7*/
    filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000);
    /* For IE 8*/
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000)";
}

In addition to this, you have to declare background: transparent for IE web browsers, preferably served via conditional comments or similar!

How about keeping all .php-files except for index.php above the web root? No need for any rewrite rules or programmatic kludges.

Adding the includes-folder to your include path will then help to keep things simple, no need to use absolute paths etc.

You can also do like this,

 <form method='POST'>
    {{form1.as_p}}
    <button type="submit" name="btnform1">Save Changes</button>
    </form>
    <form method='POST'>
    {{form2.as_p}}
    <button type="submit" name="btnform2">Save Changes</button>
    </form>

CODE

if request.method=='POST' and 'btnform1' in request.POST:
    do something...
if request.method=='POST' and 'btnform2' in request.POST:
    do something...

You have to create an instance of that class within the static method and then call it.

For example like this:

public class MyClass
{
   private void data1()
   {
   }
   private static void data2()
   {
     MyClass c = new MyClass();
     c.data1();
   }
}

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

Explicit conversions are very clear to someone that's new to the language. Using type coercion, as others have suggested, leads to ambiguity if a developer is not aware of the coercion rules. Ultimately developer time is more costly than CPU time, so I'd optimize for the former at the cost of the latter. That being said, in this case the difference is likely negligible, but if not I'm sure there are some decent JavaScript compressors that will optimize this sort of thing.

So, for the above reasons I'd go with: n.toString() or String(n). String(n) is probably a better choice because it won't fail if n is null or undefined.

This is the method I'm using in a project I am currently working on.

var exec = require('child_process').exec;
function execute(command, callback){
    exec(command, function(error, stdout, stderr){ callback(stdout); });
};

Example of retrieving a git user:

module.exports.getGitUser = function(callback){
    execute("git config --global user.name", function(name){
        execute("git config --global user.email", function(email){
            callback({ name: name.replace("\n", ""), email: email.replace("\n", "") });
        });
    });
};

To spool from a BEGIN END block is pretty simple. For example if you need to spool result from two tables into a file, then just use the for loop. Sample code is given below.

BEGIN

FOR x IN 
(
    SELECT COLUMN1,COLUMN2 FROM TABLE1
    UNION ALL
    SELECT COLUMN1,COLUMN2 FROM TABLEB
)    
LOOP
    dbms_output.put_line(x.COLUMN1 || '|' || x.COLUMN2);
END LOOP;

END;
/

Following codes will return list of names of the numeric columns of a data set.

cnames=list(marketing_train.select_dtypes(exclude=['object']).columns)

here marketing_train is my data set and select_dtypes() is function to select data types using exclude and include arguments and columns is used to fetch the column name of data set output of above code will be following:

['custAge',
     'campaign',
     'pdays',
     'previous',
     'emp.var.rate',
     'cons.price.idx',
     'cons.conf.idx',
     'euribor3m',
     'nr.employed',
     'pmonths',
     'pastEmail']

Thanks

There are two methods you can use. Both require creating a user and a database.

1. Using createuser and createdb,

   $ sudo -u postgres createuser --superuser $USER
   $ createdb mydatabase
   $ psql -d mydatabase
   

2. Using the SQL administration commands, and connecting with a password over TCP

   $ sudo -u postgres psql postgres
   

   And, then in the psql shell

   CREATE ROLE myuser LOGIN PASSWORD 'mypass';
   CREATE DATABASE mydatabase WITH OWNER = myuser;
   

   Then you can login,

   $ psql -h localhost -d mydatabase -U myuser -p <port>
   

   If you don't know the port, you can always get it by running the following, as the postgres user,

   SHOW port;
   

   Or,

   $ grep "port =" /etc/postgresql/*/main/postgresql.conf
   

Sidenote: the postgres user

I suggest NOT modifying the postgres user.

1. It's normally locked from the OS. No one is supposed to "log in" to the operating system as postgres. You're supposed to have root to get to authenticate as postgres.
2. It's normally not password protected and delegates to the host operating system. This is a good thing. This normally means in order to log in as postgres which is the PostgreSQL equivalent of SQL Server's SA, you have to have write-access to the underlying data files. And, that means that you could normally wreck havoc anyway.
3. By keeping this disabled, you remove the risk of a brute force attack through a named super-user. Concealing and obscuring the name of the superuser has advantages.

Here is some better usage of java for scanner

try(Scanner sc = new Scanner(System.in)) {

    //Use sc as you need

} catch (Exception e) {

        //  handle exception

}

This is a mistake:

m.check(side);

That code has to go inside a function. Your class definition can only contain declarations and functions.

Classes don't "run", they provide a blueprint for how to make an object.

The line Message m; means that an Orderbook will contain Message called m, if you later create an Orderbook.

Use this PATH in Windows 7:

C:\Python27;C:\Python27\Lib\site-packages\;C:\Python27\Scripts\;

You can more simply run one of the following commands:

Latest version:
nvm install node --reinstall-packages-from=node
Stable (LTS) version:
nvm install lts/* --reinstall-packages-from=node

This will install the appropriate version and reinstall all packages from the currently used node version. This saves you from manually handling the specific versions.

Edit - added command for installing LTS version according to @m4js7er comment.

this.getClass().getClassLoader().getResource("filename").getPath()

You could use THROW (available in SQL Server 2012+):

THROW 50000, 'Your custom error message', 1
THROW <error_number>, <message>, <state>

MSDN THROW (Transact-SQL)

Differences Between RAISERROR and THROW in Sql Server

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

> selects all direct descendants/children

A space selector will select all deep descendants whereas a greater than > selector will only select all immediate descendants. See fiddle for example.

div { border: 1px solid black; margin-bottom: 10px; }_x000D_
.a b { color: red; } /* every John is red */_x000D_
.b > b { color: blue; } /* Only John 3 and John 4 are blue */

<div class="a">_x000D_
  <p><b>John 1</b></p>_x000D_
  <p><b>John 2</b></p>_x000D_
  <b>John 3</b>_x000D_
  <b>John 4</b>_x000D_
</div>_x000D_

There is a really simple way to do this using a more recent version of SQL Server Management Studio (I'm using 18.4)

1. Open the "Connect to Server" dialog
2. Click the "Server Name" dropdown so it opens
3. Press the down arrow on your keyboard to highlight a server name
4. Press delete on your keyboard

Login gone! No messing around with dlls or bin files.

To answer your second query re. how encoding works, Joel Spolsky wrote a great introductory article on this. Strongly recommended.

Get-ADGroupMember "Group1" -recursive | Select-Object Name | Export-Csv c:\path\Groups.csv

I got this to work for me... I would assume that you could put "Group1, Group2, etc." or try a wildcard. I did pre-load AD into PowerShell before hand:

Get-Module -ListAvailable | Import-Module

Check if it's visible.

$("#singlechatpanel-1").is(':visible');

Check if it's hidden.

$("#singlechatpanel-1").is(':hidden');

How about s.copy().pop()? I haven't timed it, but it should work and it's simple. It works best for small sets however, as it copies the whole set.

I found on the sqlite documentation (https://www.sqlite.org/lang_datefunc.html) this text:

Compute the date and time given a unix timestamp 1092941466, and compensate for your local timezone.

SELECT datetime(1092941466, 'unixepoch', 'localtime');

That didn't look like it fit my needs, so I tried changing the "datetime" function around a bit, and wound up with this:

select datetime(timestamp, 'localtime')

That seems to work - is that the correct way to convert for your timezone, or is there a better way to do this?

You should define the style on the td element like so:

<html>
<head>
    <style type="text/css">
        .bb
        {
            border-bottom: solid 1px black;
        }
    </style>
</head>
<body>
    <table>
        <tr>
            <td>
                Test 1
            </td>
        </tr>
        <tr>
            <td class="bb">
                Test 2
            </td>
        </tr>
    </table>
</body>
</html>

1 - Make a selector file "show_password_selector.xml"

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/pwd_hide"
          android:state_selected="true"/>
    <item android:drawable="@drawable/pwd_show"
          android:state_selected="false" />
 </selector>

2 - Aet "show_password_selector" file into imageview.

<ImageView
    android:id="@+id/iv_pwd"
    android:layout_width="@dimen/_35sdp"
    android:layout_height="@dimen/_25sdp"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="@dimen/_15sdp"
    android:src="@drawable/show_password_selector" />

3 - Put below code in java file.

iv_new_pwd.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (iv_new_pwd.isSelected()) {
            iv_new_pwd.setSelected(false);
            Log.d("mytag", "in case 1");
            edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT);
        } else {
            Log.d("mytag", "in case 1");
            iv_new_pwd.setSelected(true);
            edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        }
    }
});

If you want to see a more detailed discussion of differences for the commands, see the Details about Differences section, below.

From the LeMoDa.net website¹ (archived), specifically the Windows and Unix command line equivalents page (archived), I found the following². There's a better/more complete table in the next edit.

Windows command     Unix command
rmdir               rmdir
rmdir /s            rm -r
move                mv

I'm interested to hear from @Dave and @javadba to hear how equivalent the commands are - how the "behavior and capabilities" compare, whether quite similar or "woefully NOT equivalent".

All I found out was that when I used it to try and recursively remove a directory and its constituent files and subdirectories, e.g.

(Windows cmd)>rmdir /s C:\my\dirwithsubdirs\

gave me a standard Windows-knows-better-than-you-do-are-you-sure message and prompt

dirwithsubdirs, Are you sure (Y/N)?

and that when I typed Y, the result was that my top directory and its constituent files and subdirectories went away.

Edit

I'm looking back at this after finding this answer. I retried each of the commands, and I'd change the table a little bit.

Windows command     Unix command
rmdir               rmdir
rmdir /s /q         rm -r
rmdir /s /q         rm -rf
rmdir /s            rm -ri
move                mv
del <file>          rm <file>

If you want the equivalent for

rm -rf

you can use

rmdir /s /q

or, as the author of the answer I sourced described,

But there is another "old school" way to do it that was used back in the day when commands did not have options to suppress confirmation messages. Simply ECHO the needed response and pipe the value into the command.

echo y | rmdir /s

Details about Differences

I tested each of the commands using Windows CMD and Cygwin (with its bash).

Before each test, I made the following setup.

Windows CMD

>mkdir this_directory
>echo some text stuff > this_directory/some.txt
>mkdir this_empty_directory

Cygwin bash

$ mkdir this_directory
$ echo "some text stuff" > this_directory/some.txt
$ mkdir this_empty_directory

That resulted in the following file structure for both.

base
|-- this_directory
|   `-- some.txt
`-- this_empty_directory

Here are the results. Note that I'll not mark each as CMD or bash; the CMD will have a > in front, and the bash will have a $ in front.

RMDIR

>rmdir this_directory
The directory is not empty.

>tree /a /f .
Folder PATH listing for volume Windows
Volume serial number is ¦¦¦¦¦¦¦¦ ¦¦¦¦:¦¦¦¦
base
+---this_directory
|       some.txt
|
\---this_empty_directory

> rmdir this_empty_directory

>tree /a /f .
base
\---this_directory
        some.txt

$ rmdir this_directory
rmdir: failed to remove 'this_directory': Directory not empty

$ tree --charset=ascii
base
|-- this_directory
|   `-- some.txt
`-- this_empty_directory

2 directories, 1 file

$ rmdir this_empty_directory

$ tree --charset=ascii
base
`-- this_directory
    `-- some.txt

RMDIR /S /Q and RM -R ; RM -RF

>rmdir /s /q this_directory

>tree /a /f
base
\---this_empty_directory

>rmdir /s /q this_empty_directory

>tree /a /f
base
No subfolders exist

$ rm -r this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -r this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

$ rm -rf this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -rf this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

RMDIR /S AND RM -RI Here, we have a bit of a difference, but they're pretty close.

>rmdir /s this_directory
this_directory, Are you sure (Y/N)? y

>tree /a /f
base
\---this_empty_directory

>rmdir /s this_empty_directory
this_empty_directory, Are you sure (Y/N)? y

>tree /a /f
base
No subfolders exist

$ rm -ri this_directory
rm: descend into directory 'this_directory'? y
rm: remove regular file 'this_directory/some.txt'? y
rm: remove directory 'this_directory'? y

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -ri this_empty_directory
rm: remove directory 'this_empty_directory'? y

$ tree --charset=ascii
base
0 directories, 0 files

I'M HOPING TO GET A MORE THOROUGH MOVE AND MV TEST

and that there seem to be a bunch of useful programming tips along with some humour (yes, the British spelling) and information on how to fix Japanese toilets. I also found some stuff talking about the "Ibaraki Report", but I don't know if that is the website.

I think I shall go there more often; it's quite useful. Props to Ben Bullock, whose email is on his page. If he wants me to remove this info, I will.

2. Actually, I found the information with a Google search for "cmd equivalent of rm"

https://www.google.com/search?q=cmd+equivalent+of+rm

The information I'm sharing came up first.

A DateTime in C# is a value type, not a reference type, and therefore cannot be null. It can however be the constant DateTime.MinValue which is outside the range of Sql Servers DATETIME data type.

Value types are guaranteed to always have a (default) value (of zero) without always needing to be explicitly set (in this case DateTime.MinValue).

Conclusion is you probably have an unset DateTime value that you are trying to pass to the database.

DateTime.MinValue = 1/1/0001 12:00:00 AM
DateTime.MaxValue = 23:59:59.9999999, December 31, 9999, 
                    exactly one 100-nanosecond tick 
                    before 00:00:00, January 1, 10000

MSDN: DateTime.MinValue

Regarding Sql Server

datetime
Date and time data from January 1, 1753 through December 31, 9999, to an accuracy of one three-hundredth of a second (equivalent to 3.33 milliseconds or 0.00333 seconds). Values are rounded to increments of .000, .003, or .007 seconds

smalldatetime
Date and time data from January 1, 1900, through June 6, 2079, with accuracy to the minute. smalldatetime values with 29.998 seconds or lower are rounded down to the nearest minute; values with 29.999 seconds or higher are rounded up to the nearest minute.

MSDN: Sql Server DateTime and SmallDateTime

Lastly, if you find yourself passing a C# DateTime as a string to sql, you need to format it as follows to retain maximum precision and to prevent sql server from throwing a similar error.

string sqlTimeAsString = myDateTime.ToString("yyyy-MM-ddTHH:mm:ss.fff");

Update (8 years later)

Consider using the sql DateTime2 datatype which aligns better with the .net DateTime with date range 0001-01-01 through 9999-12-31 and time range 00:00:00 through 23:59:59.9999999

string dateTime2String = myDateTime.ToString("yyyy-MM-ddTHH:mm:ss.fffffff");

MSDN datetime2 (Transact-SQL)

• On Unix, it's in $HOME/.subversion/auth.

• On Windows, I think it's: %APPDATA%\Subversion\auth.

I may be wrong, but I believe I've seen a list of previous SQL queries in the session file for phpmyadmin sessions

I've developed a python package called: parallel_sync

https://pythonhosted.org/parallel_sync/pages/examples.html

Here is a sample code how to use it:

from parallel_sync import rsync
creds = {'user': 'myusername', 'key':'~/.ssh/id_rsa', 'host':'192.168.16.31'}
rsync.upload('/tmp/local_dir', '/tmp/remote_dir', creds=creds)

parallelism by default is 10; you can increase it:

from parallel_sync import rsync
creds = {'user': 'myusername', 'key':'~/.ssh/id_rsa', 'host':'192.168.16.31'}
rsync.upload('/tmp/local_dir', '/tmp/remote_dir', creds=creds, parallelism=20)

however note that ssh typically has the MaxSessions by default set to 10 so to increase it beyond 10, you'll have to modify your ssh settings.

It can also be retrieved from the registry:

Get-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters' |
   % { $_.'NV HostName', $_.'NV Domain' -join '.' }

This thread is ancient, but I wasn't happy with any of the given answers, and ended up writing my own. I'm sharing it now:

We start with:

  Sub ResetWSFilters(ws as worksheet)
             If ws.FilterMode Then   
     ws.ShowAllData   
     Else   
     End If  
    'This gets rid of "normal" filters - but tables will remain filtered
    For Each listObj In ws.ListObjects 
               If listObj.ShowHeaders Then   
                    listObj.AutoFilter.ShowAllData
                    listObj.Sort.SortFields.Clear    
               End If     
       Next listObj
        'And this gets rid of table filters
        End Sub

We can feed a specific worksheet to this macro which will unfilter just that one worksheet. Useful if you need to make sure just one worksheet is clear. However, I usually want to do the entire workbook

Sub ResetAllWBFilters(wb as workbook)
  Dim ws As Worksheet  
  Dim wb As Workbook  
  Dim listObj As ListObject    

       For Each ws In wb.Worksheets  
          If ws.FilterMode Then 
          ws.ShowAllData  
          Else   
          End If   
 'This removes "normal" filters in the workbook - however, it doesn't remove table filters           
   For Each listObj In ws.ListObjects 
        If listObj.ShowHeaders Then   
             listObj.AutoFilter.ShowAllData 
             listObj.Sort.SortFields.Clear    
        End If     
   Next listObj

        Next   
'And this removes table filters. You need both aspects to make it work.  
    End Sub

You can use this, by, for example, opening a workbook you need to deal with and resetting their filters before doing anything with it:

Sub ExampleOpen()
Set TestingWorkBook = Workbooks.Open("C:\Intel\......") 'The .open is assuming you need to open the workbook in question - different procedure if it's already open
Call ResetAllWBFilters(TestingWorkBook)
End Sub

The one I use the most: Resetting all filters in the workbook that the module is stored in:

Sub ResetFilters()
      Dim ws As Worksheet  
      Dim wb As Workbook  
      Dim listObj As ListObject  
       Set wb = ThisWorkbook  
       'Set wb = ActiveWorkbook
       'This is if you place the macro in your personal wb to be able to reset the filters on any wb you're currently working on. Remove the set wb = thisworkbook if that's what you need
           For Each ws In wb.Worksheets  
              If ws.FilterMode Then 
              ws.ShowAllData  
              Else   
              End If   
     'This removes "normal" filters in the workbook - however, it doesn't remove table filters           
       For Each listObj In ws.ListObjects 
            If listObj.ShowHeaders Then   
                 listObj.AutoFilter.ShowAllData 
                 listObj.Sort.SortFields.Clear    
            End If     
       Next listObj

            Next   
'And this removes table filters. You need both aspects to make it work.  
    End Sub

To grant a permission:

grant select on schema_name.sequence_name to user_or_role_name;

To check which permissions have been granted

select * from all_tab_privs where TABLE_NAME = 'sequence_name'

Don't define the height as a percent, just set the top=0 and bottom=0, like this:

#div {
   top: 0; bottom: 0;
   position: absolute;
   width: 100%;
}

For me the problem was the port. I first incorrectly used port 465, which works for SSL but not TLS. So the key thing was changing the port to 587.

this is my answer, just use while and for

def remove_all(data, value):
    i = j = 0
    while j < len(data):
        if data[j] == value:
            j += 1
            continue
        data[i] = data[j]
        i += 1
        j += 1
    for x in range(j - i):
        data.pop()

Toggle between two classes 'A' and 'B' with Jquery.

$('#selecor_id').toggleClass("A B");

You're looking for the MemoryStream.Write method.

For example, the following code will write the contents of a byte[] array into a memory stream:

byte[] myByteArray = new byte[10];
MemoryStream stream = new MemoryStream();
stream.Write(myByteArray, 0, myByteArray.Length);

Alternatively, you could create a new, non-resizable MemoryStream object based on the byte array:

byte[] myByteArray = new byte[10];
MemoryStream stream = new MemoryStream(myByteArray);

You can use jquery's load function here.

$("#your_element_id").load("file_name.html");

If you need more info, here is the link.

You have to store the content as a fact:

- set_fact:
    string_to_echo: "{{ command_output.stdout }}"

I believe those who study typography would tell you that 66 characters per a line is supposed to be the most readable width for length. Even so, if you need to debug a machine remotely over an ssh session, most terminals default to 80 characters, 79 just fits, trying to work with anything wider becomes a real pain in such a case. You would also be suprised by the number of developers using vim + screen as a day to day environment.

You need to call repaint() and revalidate(). The former tells Swing that an area of the window is dirty (which is necessary to erase the image of the old children removed by removeAll()); the latter tells the layout manager to recalculate the layout (which is necessary when adding components). This should cause children of the panel to repaint, but may not cause the panel itself to do so (see this for the list of repaint triggers).

On a more general note: rather than reusing the original panel, I'd recommend building a new panel and swapping them at the parent.

You can use jQuery change() function

$('input').change(function(){
  //your codes
});

There are examples on how to use it on the API Page: http://api.jquery.com/change/

The absolute easiest method if all you want to run is a simple script, (or anything) is if you have a gui to use system > preferences then startup apps.

just browse to the script you want and there you go. (make script executable)

you need to put a textvariable in it, so you can use set() and get() method :

var=StringVar()
x= Entry (root,textvariable=var)

Hope this helps for item #2: a) You can sort by total bill then reset the index to this column b) Use palette="Blue" to use this color to scale your chart from light blue to dark blue (if dark blue to light blue then use palette="Blues_d")

import pandas as pd
import seaborn as sns
%matplotlib inline

df=pd.read_csv("https://raw.githubusercontent.com/wesm/pydata-book/master/ch08/tips.csv", sep=',')
groupedvalues=df.groupby('day').sum().reset_index()
groupedvalues=groupedvalues.sort_values('total_bill').reset_index()

If you have a copy of backup of SQL Server setup then you could add features (Management Tools Basic/Complete) as you requested.

Please use the below steps in Windows machine:

1. Go to Control Panel -> Programs -> Program and Features -> Select your current version of Microsoft SQL Server
2. Right Click, select Change/Uninstall
3. Click Add features
4. Select the backup copy folder
5. Do the steps what you done for SQL Server installation until features selection
6. Now select the features Management Tools Basic/Complete or both
7. And go ahead with process for complete installation.
8. Now you should get, SQL Server Management Studio and you can browse your databases.

Another easy way to execute a ps script from batch is to simply incorporate it between the ECHO and the Redirection characters,(> and >>), example:

@echo off
set WD=%~dp0
ECHO New-Item -Path . -Name "Test.txt" -ItemType "file" -Value "This is a text string." -Force > "%WD%PSHELLFILE.ps1"
ECHO add-content -path "./Test.txt" -value "`r`nThe End" >> "%WD%PSHELLFILE.ps1"
powershell.exe -ExecutionPolicy Bypass -File "%WD%PSHELLFILE.ps1"
del "%WD%PSHELLFILE.ps1"

Last line deletes the created temp file.

On some systems (Windows with VC springs to mind, currently), RAND_MAX is ridiculously small, i. e. only 15 bit. When dividing by RAND_MAX you are only generating a mantissa of 15 bit instead of the 23 possible bits. This may or may not be a problem for you, but you're missing out some values in that case.

Oh, just noticed that there was already a comment for that problem. Anyway, here's some code that might solve this for you:

float r = (float)((rand() << 15 + rand()) & ((1 << 24) - 1)) / (1 << 24);

Untested, but might work :-)

It's not bad to use a wild card with a Java import statement.

In Clean Code, Robert C. Martin actually recommends using them to avoid long import lists.

Here is the recommendation:

J1: Avoid Long Import Lists by Using Wildcards

If you use two or more classes from a package, then import the whole package with

import package.*;

Long lists of imports are daunting to the reader. We don’t want to clutter up the tops of our modules with 80 lines of imports. Rather we want the imports to be a concise statement about which packages we collaborate with.

Specific imports are hard dependencies, whereas wildcard imports are not. If you specifically import a class, then that class must exist. But if you import a package with a wildcard, no particular classes need to exist. The import statement simply adds the package to the search path when hunting for names. So no true dependency is created by such imports, and they therefore serve to keep our modules less coupled.

There are times when the long list of specific imports can be useful. For example, if you are dealing with legacy code and you want to find out what classes you need to build mocks and stubs for, you can walk down the list of specific imports to find out the true qualified names of all those classes and then put the appropriate stubs in place. However, this use for specific imports is very rare. Furthermore, most modern IDEs will allow you to convert the wildcarded imports to a list of specific imports with a single command. So even in the legacy case it’s better to import wildcards.

Wildcard imports can sometimes cause name conflicts and ambiguities. Two classes with the same name, but in different packages, will need to be specifically imported, or at least specifically qualified when used. This can be a nuisance but is rare enough that using wildcard imports is still generally better than specific imports.

If the worksheet you want to retrieve exists at compile-time in ThisWorkbook (i.e. the workbook that contains the VBA code you're looking at), then the simplest and most consistently reliable way to refer to that Worksheet object is to use its code name:

Debug.Print Sheet1.Range("A1").Value

You can set the code name to anything you need (as long as it's a valid VBA identifier), independently of its "tab name" (which the user can modify at any time), by changing the (Name) property in the Properties toolwindow (F4):

The Name property refers to the "tab name" that the user can change on a whim; the (Name) property refers to the code name of the worksheet, and the user can't change it without accessing the Visual Basic Editor.

VBA uses this code name to automatically declare a global-scope Worksheet object variable that your code gets to use anywhere to refer to that sheet, for free.

In other words, if the sheet exists in ThisWorkbook at compile-time, there's never a need to declare a variable for it - the variable is already there!

If the worksheet is created at run-time (inside ThisWorkbook or not), then you need to declare & assign a Worksheet variable for it.

Use the Worksheets property of a Workbook object to retrieve it:

Dim wb As Workbook
Set wb = Application.Workbooks.Open(path)

Dim ws As Worksheet
Set ws = wb.Worksheets(nameOrIndex)

Important notes...

• Both the name and index of a worksheet can easily be modified by the user (accidentally or not), unless workbook structure is protected. If workbook isn't protected, you simply cannot assume that the name or index alone will give you the specific worksheet you're after - it's always a good idea to validate the format of the sheet (e.g. verify that cell A1 contains some specific text, or that there's a table with a specific name, that contains some specific column headings).

• Using the Sheets collection contains Worksheet objects, but can also contain Chart instances, and a half-dozen more legacy sheet types that are not worksheets. Assigning a Worksheet reference from whatever Sheets(nameOrIndex) returns, risks throwing a type mismatch run-time error for that reason.

• Not qualifying the Worksheets collection is an implicit ActiveWorkbook reference - meaning the Worksheets collection is pulling from whatever workbook is active at the moment the instruction is executing. Such implicit references make the code frail and bug-prone, especially if the user can navigate and interact with the Excel UI while code is running.

• Unless you mean to activate a specific sheet, you never need to call ws.Activate in order to do 99% of what you want to do with a worksheet. Just use your ws variable instead.

The 2 highest upvoted answers are correct. As of today, the only thing I needed to change (from default settings) was to enable generation using dot instead of the built-in generator.

Some important notes:

• Doxygen will not generate an actual full diagram of all classes in the project. It will generate a separate image for each hierarchy. If you have multiple, unrelated class hierarchies you will get multiple images.
• All these diagrams can be found in html/inherits.html or (from the website navigation) classes => class hierarchy => "Go to the textual class hierarchy".
• This is a C++ question, so let's talk about templates. Especially if you inherit from T.
  • Each template instantiation will be correctly considered a different type by Doxygen. Types which inherit from different instantations will have different parent classes on the diagram.
  • If a class template foo inherits from T and the T template type parameter has a default, such default will be assumed. If there is a type bar which inherits from foo<U> where U is different than the default, bar will have a foo<U> parent. foo<> and bar<U> will not have a common parent.
  • If there are multiple class templates which inherit from at least one of their template parameters, Doxygen will assume a common parent for these class templates as long as the template type parameters have exactly the same names in the code. This incentivizes for consistency in naming.
  • CRTP and reverse CRTP just work.
  • Recursive template inheritance trees are not expanded. Any variant instantiation will be displayed to inherit from variant<Ts...>.
  • Class templates with no instantiations are being drawn. They will have a <...> string in their name representing type and non-type parameters which did not have defaults.
  • Class template full and partial specializations are also being drawn. Doxygen generates correct graphs if specializations inherit from different types.

You're getting final 0 because your while loop is being executed in a sub (shell) process and any changes made there are not reflected in the current (parent) shell.

Correct script:

while read -r country _; do
  if [ "US" = "$country" ]; then
        ((USCOUNTER++))
        echo "US counter $USCOUNTER"
  fi
done < "$FILE"

Most of the answers here are offering to delete random files.

Most of the time, this is the worst thing to do especially if it is important for you to keep the integrity of your development environment.

As explained in the log file, if this problem is not related to a read access permission nor to a file you deleted in your mysql then the only solution is to:

Open your my.conf file from the File menu in MAMP (File > Edit Template > MySQL)

Find and edit this line to be: innodb_force_recovery = 1

Save with ctrl+S

MAMP will offer you to restart your servers

First of all, check whether the API you created in the lamda function is registered with your AWS project or not. For that, go to the API gateway in your AWS console. If it is not registered, register it. This is the main cause of this issue.

You can even see in your aws.export.js file, that there are paths corresponding to your API ['/items'].

Your API must be present there, otherwise it will not append the security token to requests. Just register it in your project cloud-logic in your console for this.

If it's there, then use the above mentioned solution
http://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-use-postman-to-call-api.html

I had this problem, but only when I tried to rsync from a Linux (RH) server to a Solaris server. My fix was to make sure rsync had the same path on both boxes, and that the ownership of rsync was the same.

On the linux box, rsync path was /usr/bin, on Solaris box it was /usr/local/bin. So, on the Solaris box I did ln -s /usr/local/bin/rsync /usr/bin/rsync.

I still had the same problem, and noticed ownership differences. On linux it was root:root, on solaris it was bin:bin. Changing solaris to root:root fixed it.

Here's a simple pure JavaScript solution that works for a target Number (value for scrollTop), target DOM element, or some special String cases:

/**
 * target - target to scroll to (DOM element, scrollTop Number, 'top', or 'bottom'
 * containerEl - DOM element for the container with scrollbars
 */
var scrollToTarget = function(target, containerEl) {
    // Moved up here for readability:
    var isElement = target && target.nodeType === 1,
        isNumber = Object.prototype.toString.call(target) === '[object Number]';

    if (isElement) {
        containerEl.scrollTop = target.offsetTop;
    } else if (isNumber) {
        containerEl.scrollTop = target;
    } else if (target === 'bottom') {
        containerEl.scrollTop = containerEl.scrollHeight - containerEl.offsetHeight;
    } else if (target === 'top') {
        containerEl.scrollTop = 0;
    }
};

And here are some examples of usage:

// Scroll to the top
var scrollableDiv = document.getElementById('scrollable_div');
scrollToTarget('top', scrollableDiv);

or

// Scroll to 200px from the top
var scrollableDiv = document.getElementById('scrollable_div');
scrollToTarget(200, scrollableDiv);

or

// Scroll to targetElement
var scrollableDiv = document.getElementById('scrollable_div');
var targetElement= document.getElementById('target_element');
scrollToTarget(targetElement, scrollableDiv);

You can use a factory to create the login context. Then you can mock the factory and return whatever you want for your test.

public class TestedClass {
  private final LoginContextFactory loginContextFactory;

  public TestedClass(final LoginContextFactory loginContextFactory) {
    this.loginContextFactory = loginContextFactory;
  }

  public LoginContext login(String user, String password) {
    LoginContext lc = loginContextFactory.createLoginContext();
  }
}

public interface LoginContextFactory {
  public LoginContext createLoginContext();
}

1. Press the Apps menu button on your Android mobile phone device. It will display icons of all the apps installed on your mobile phone device. Press Settings.

2. Press Apps. (Pressing on Apps button will list down all the apps installed on your mobile phone.

3. Browse the Apps list and press on the app called "Launcher 3". (Launcher 3 is an app and it will be listed in the App list whenever you access Settings > Apps in your android phone).

4. Pressing on the "Launcher 3" app will open the "App info screen" which will show some details pertaining to that app. On this App info screen, you will find buttons like "Force Stop", "Uninstall", "Clear Data" and "Clear Cache" etc.

5. In Android Marshmallow (i.e. Android 6.0) choose Settings > Apps > Launcher3 > STORAGE. Press "Clear Cache". If this fails, press "Clear data". This will eventually restore functionality, but all custom shortcuts will be lost.

Restart the phone and its done. All the home screens along with app shortcuts will appear again and your mobile phone is at your service again.

I hope it explains well on how to solve the launcher problem in Android. Worked for me.

You are trying to access an XLS file. However, you are using XSSFWorkbook and XSSFSheet class objects. These classes are mainly used for XLSX files.

For XLS file: HSSFWorkbook & HSSFSheet
For XLSX file: XSSFSheet & XSSFSheet

So in place of XSSFWorkbook use HSSFWorkbook and in place of XSSFSheet use HSSFSheet.

So your code should look like this after the changes are made:

HSSFWorkbook workbook = new HSSFWorkbook(file);

HSSFSheet sheet = workbook.getSheetAt(0);

I was confused between the two processes. I found this simple explaination about the difference between Emulators and Simulators

1. Simulator:
   Suppose you have written assembly program in a file and corresponding exe file is ready. The simulator is the pc software which reads the instructions from the exe and 'minmics' the operation of the processor.

2. Emulator:
   Emulator is a (PC software + a processor). The Processor can be plugged into the TARGET BOARD when you want to test the developed software in real time to check run time bugs. When not in use it can be unplugged. The Processor will have a parallel or JTAG interface with the PC for downloading the exe file for execution.

Hence, whereas the Simulator is slow in execution, Emulator will be able to give real time verification of the developed code. Generally you will test your developed code on simulator first and then go for checking on emulator.

Use df.schema.names:

spark.version
# u'2.2.0'

df = spark.createDataFrame([("foo", 1), ("bar", 2)])
df.show()
# +---+---+ 
# | _1| _2|
# +---+---+
# |foo|  1| 
# |bar|  2|
# +---+---+

df.schema.names
# ['_1', '_2']

for i in df.schema.names:
  # df_new = df.withColumn(i, [do-something])
  print i
# _1
# _2

Change this:

`create_date` TIMESTAMP NOT NULL DEFAULT  '0000-00-00 00:00:00',
`update_date` TIMESTAMP NOT NULL DEFAULT  CURRENT_TIMESTAMP  ,

To the following:

`create_date` TIMESTAMP NOT NULL DEFAULT  CURRENT_TIMESTAMP ,
`update_date` TIMESTAMP NOT NULL DEFAULT  CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ,

You can download the wheel corresponding to your configuration here ("Pillow-4.1.1-cp36-cp36m-win_amd64.whl" in your case) and install it with:

pip install some-package.whl

If you have problem to install the wheel read this answer

Do this, it will work.

trim(replace(ntwk_slctor_key_txt, chr(0), ''))

Just use

int listCount = data.size();

That tells you how many lists there are (assuming none are null). If you want to find out how many strings there are, you'll need to iterate:

int total = 0;
for (List<String> sublist : data) {
    // TODO: Null checking
    total += sublist.size();
}
// total is now the total number of strings

I think this works:

int roundUp(int numToRound, int multiple) {
    return multiple? !(numToRound%multiple)? numToRound : ((numToRound/multiple)+1)*multiple: numToRound;
}

You could try this registry hack:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"DeadGWDetectDefault"=dword:00000001
"KeepAliveTime"=dword:00120000

If it works, just keep increasing the KeepAliveTime. It is currently set for 2 minutes.

Can't comment because I don't have enough reputation points, but recode only works on a vector, so the above code in @Stefano's answer should be

df <- iris %>%
  mutate(Species = recode(Species, 
     setosa = "SETOSA",
     versicolor = "VERSICOLOR",
     virginica = "VIRGINICA")
  )

This works for me in Kotlin:

when(list.get(0)).thenThrow(new ArrayIndexOutOfBoundsException());

Note : Throw any defined exception other than Exception()

Addition to @jwize's answer

Because angular.element(document).injector() was giving error injector is not defined So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.

  function compileAngularElement( elSelector) {

        var elSelector = (typeof elSelector == 'string') ? elSelector : null ;  
            // The new element to be added
        if (elSelector != null ) {
            var $div = $( elSelector );

                // The parent of the new element
                var $target = $("[ng-app]");

              angular.element($target).injector().invoke(['$compile', function ($compile) {
                        var $scope = angular.element($target).scope();
                        $compile($div)($scope);
                        // Finally, refresh the watch expressions in the new element
                        $scope.$apply();
                    }]);
            }

        }

use it by passing just new element's selector. like this

compileAngularElement( '.user' ) ; 

Example to show last 3 digits of account number.

x = '1234567890'   
x.replace(x[:7], '')

o/p: '890'

I noticed this wasn't working with a static-first-then-reverse-proxy setup. Here's what that looks like:

location @app {
  proxy_pass http://localhost:3000$request_uri;
}

location / {
  try_files $uri $uri/ @app;
  error_page 405 @app;
}

The "IN" clause is built into linq via the .Contains() method.

For example, to get all People whose .States's are "NY" or "FL":

using (DataContext dc = new DataContext("connectionstring"))
{
    List<string> states = new List<string>(){"NY", "FL"};
    List<Person> list = (from p in dc.GetTable<Person>() where states.Contains(p.State) select p).ToList();
}

Not exactly the case of this question but can be helpful. I got this exception when i call mkdirs() on new file instead of its parent

File file = new java.io.File(path);
//file.mkdirs(); // wrong! 
file.getParentFile().mkdirs(); // correct!
if (!file.exists()) {
    file.createNewFile();
} 

namespace: modules are namespaces...which don't exist in java ;)

I also switched from Java and python to Ruby, I remember had exactly this same question...

So the simplest answer is that module is a namespace, which doesn't exist in Java. In java the closest mindset to namespace is a package.

So a module in ruby is like what in java:
class? No
interface? No
abstract class? No
package? Yes (maybe)

static methods inside classes in java: same as methods inside modules in ruby

In java the minimum unit is a class, you can't have a function outside of a class. However in ruby this is possible (like python).

So what goes into a module?
classes, methods, constants. Module protects them under that namespace.

No instance: modules can't be used to create instances

Mixed ins: sometimes inheritance models are not good for classes, but in terms of functionality want to group a set of classes/ methods/ constants together

Rules about modules in ruby:
- Module names are UpperCamelCase
- constants within modules are ALL CAPS (this rule is the same for all ruby constants, not specific to modules)
- access methods: use . operator
- access constants: use :: symbol

simple example of a module:

module MySampleModule
  CONST1 = "some constant"

  def self.method_one(arg1)
    arg1 + 2
  end
end

how to use methods inside a module:

puts MySampleModule.method_one(1) # prints: 3

how to use constants of a module:

puts MySampleModule::CONST1 # prints: some constant

Some other conventions about modules:
Use one module in a file (like ruby classes, one class per ruby file)

You could try this:

1. Open the Terminal application. It can be found in the Utilities directory inside the Applications directory.
2. Type the following: echo 'export PATH=YOURPATHHERE:$PATH' >> ~/.profile, replacing "YOURPATHHERE" with the name of the directory you want to add. Make certain that you use ">>" instead of one ">".
3. Hit Enter.
4. Close the Terminal and reopen. Your new Terminal session should now use the new PATH.

Use arbitrary, extensible object, and then serialize it to JSON:

import json

class Object(object):
    pass

response = Object()
response.debug = []
response.result = Object()

# Any manipulations with the object:
response.debug.append("Debug string here")
response.result.body = "404 Not Found"
response.result.code = 404

# Proper JSON output, with nice formatting:
print(json.dumps(response, indent=4, default=lambda x: x.__dict__))

You can return dynamic which will give you a runtime checked version of the anonymous type but only in .NET 4+

Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.

Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080

What you get as a result is the standalone 1080p video but not in the Tube environment.

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

Not exactly correct, to be precise:

1. if isHere is true, the result of getHereCount() is returned
2. otheriwse the result of getAwayCount() is returned

That "returned" is very important. It means the methods must return a value and that value must be assigned somewhere.

Also, it's not exactly syntactically equivalent to the if-else version. For example:

String str1,str2,str3,str4;
boolean check;
//...
return str1 + (check ? str2 : str3) + str4;

If coded with if-else will always result in more bytecode.

I've refactored your code a bit, this should work:

jQuery("#loadActive").click(writeData);

function writeData() {
    jQuery("#chatTickets input:radio").attr('disabled',true);
}

If there are more than two radio buttons on your form, you'll have to modify the selector, for example, you can use the starts with attribute filter to pick out the radios whose ID starts with ticketID:

function writeData() {
    jQuery("#chatTickets input[id^=ticketID]:radio").attr('disabled',true);
}

I spent couple hours to figure out proper way to do it. In my case I'm trying to define global "log" variable so the steps were:

1) configure your tsconfig.json to include your defined types (src/types folder, node_modules - is up to you):

...other stuff...
"paths": {
  "*": ["node_modules/*", "src/types/*"]
}

2) create file src/types/global.d.ts with following content (no imports! - this is important), feel free to change any to match your needs + use window interface instead of NodeJS if you are working with browser:

/**
 * IMPORTANT - do not use imports in this file!
 * It will break global definition.
 */
declare namespace NodeJS {
    export interface Global {
        log: any;
    }
}

declare var log: any;

3) now you can finally use/implement log where its needed:

// in one file
global.log = someCoolLogger();
// in another file
log.info('hello world');
// or if its a variable
global.log = 'INFO'

In my case, I had to copy over a job from one jenkins instance to another.

So first I looked under the directory structure of the old Jenkins (the job/directory name; also noted the config.xml) and then under the directory structure of the new jenkins where I then created a directory with same name/job and copied over the config.xml under this newly created dir.

Then under, "Manage Jenkins", I hit "Reload Configuration from Disk". Thats it.

I agree with the use of instanceof already mentioned.

An additional benefit of using instanceof is that when used with a null reference instanceof of will return false, while a.getClass() would throw a NullPointerException.

You can also use firstOrCreate OR firstOrNew

// Retrieve the Post by the attributes, or create it if it doesn't exist...
$post = Post::firstOrCreate(['id' => 3]);
// OR
// Retrieve the Post by the attributes, or instantiate a new instance...
$post = Post::firstOrNew(['id' => 3]); 

// update record
$post->title = "Updated title";
$post->save();

Hope it will help you :)

You can use Random.nextInt(n). This returns a random int in [0,n). Just using max-min+1 in place of n and adding min to the answer will give a value in the desired range.

update Angular 5

ngOutletContext was renamed to ngTemplateOutletContext

See also https://github.com/angular/angular/blob/master/CHANGELOG.md#500-beta5-2017-08-29

original

Templates (<template>, or <ng-template> since 4.x) are added as embedded views and get passed a context.

With let-col the context property $implicit is made available as col within the template for bindings. With let-foo="bar" the context property bar is made available as foo.

For example if you add a template

<ng-template #myTemplate let-col let-foo="bar">
  <div>{{col}}</div>
  <div>{{foo}}</div>
</ng-template>

<!-- render above template with a custom context -->
<ng-template [ngTemplateOutlet]="myTemplate"
             [ngTemplateOutletContext]="{
                                           $implicit: 'some col value',
                                           bar: 'some bar value'
                                        }"
></ng-template>

See also this answer and ViewContainerRef#createEmbeddedView.

*ngFor also works this way. The canonical syntax makes this more obvious

<ng-template ngFor let-item [ngForOf]="items" let-i="index" let-odd="odd">
  <div>{{item}}</div>
</ng-template>

where NgFor adds the template as embedded view to the DOM for each item of items and adds a few values (item, index, odd) to the context.

I don't know why this answer hasn't already been given:

Different callers of the same library will, in general, use different configurations. This implies that the configuration must reside in the executable application, and not in the class library.

You may create an app.config within the class library project. It will contain default configurations for items you create within the library. For instance, it will contain connection strings if you create an Entity Framework model within the class library.

However, these settings will not be used by the executable application calling the library. Instead, these settings may be copied from the library.dll.config file into the app.config or web.config of the caller, so that they may be changed to be specific to the caller, and to the environment into which the caller is deployed.

This is how it has been with .NET since Day 1.

I found dfsq's answer its comments extremely useful. I made some minor modifications applicable to me (and I'm posting it here, in case it is of some use to others).

1. Using class as hooks, instead of table elements tr
2. Searching/comparing text within a child class while showing/hiding parent
3. Making it more efficient by storing the $rows text elements into an array only once (and avoiding $rows.length times computation)

var $rows = $('.wrapper');
var rowsTextArray = [];

var i = 0;
$.each($rows, function () {
    rowsTextArray[i] = ($(this).find('.number').text() + $(this).find('.fruit').text())
        .replace(/\s+/g, '')
        .toLowerCase();
    i++;
});

$('#search').keyup(function() {
  var val = $.trim($(this).val()).replace(/\s+/g, '').toLowerCase();
  $rows.show().filter(function(index) {
    return (rowsTextArray[index].indexOf(val) === -1);
  }).hide();
});

span {
  margin-right: 0.2em;
}

<input type="text" id="search" placeholder="type to search" />

<div class="wrapper"><span class="number">one</span><span class="fruit">apple</span></div>
<div class="wrapper"><span class="number">two</span><span class="fruit">banana</span></div>
<div class="wrapper"><span class="number">three</span><span class="fruit">cherry</span></div>
<div class="wrapper"><span class="number">four</span><span class="fruit">date</span></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Using new api fetch:

You will not only have to use an asp.net page but

If using the Entity Framework or LinqToSql (if using partial classes) move the data into a separate project, the report designer cannot see the classes.

Move the reports to another project/dll, VS10 has bugs were asp.net projects cannot see object datasources in web apps. Then stream the reports from the dll into your mvc projects aspx page.

This applies for mvc and webform projects. Using sql reports in the local mode is not a pleasent development experience. Also watch your webserver memory if exporting large reports. The reportviewer/export is very poorly designed.

You can use appJar for basic GUI development.

from appJar import gui

num=1

def myfcn(btnName):   
    global num
    num +=1
    win.setLabel("mylabel", num)

win = gui('Test')

win.addButtons(["Set"],  [myfcn])
win.addLabel("mylabel", "Press the Button")

win.go()

See documentation at appJar site.

Installation is made with pip install appjar from command line.

In powershell you should use ${pwd} vs $(pwd)

Here is another way to do it. I have used it in some cases and it's working.

Function IsArrayEmpty(arr As Variant) As Boolean

Dim index As Integer

index = -1
    On Error Resume Next
        index = UBound(arr)
    On Error GoTo 0

If (index = -1) Then IsArrayEmpty = True Else IsArrayEmpty = False

End Function

While there is a maven command you can execute to do this, it's easier to just delete the files manually from the repository.

Like this on windows Documents and Settings\your username\.m2 or $HOME/.m2 on Linux

svn info, I believe, is what you want.

If you just wanted the revision, maybe you could do something like:

svn info | grep "Revision:"

Try this query

SELECT v.VehicleId, v.Name, ll.LocationList
FROM Vehicles v 
LEFT JOIN 
    (SELECT 
     DISTINCT
        VehicleId,
        REPLACE(
            REPLACE(
                REPLACE(
                    (
                        SELECT City as c 
                        FROM Locations x 
                        WHERE x.VehicleID = l.VehicleID FOR XML PATH('')
                    ),    
                    '</c><c>',', '
                 ),
             '<c>',''
            ),
        '</c>', ''
        ) AS LocationList
    FROM Locations l
) ll ON ll.VehicleId = v.VehicleId

round(number, 1)

echo %Date:~7,2% gets current day

7 is starting position 2 number of digits to display

echo %Date:~7,2% gets current day

echo %Date:~4,2% gets current month

echo %Date:~10,4% gets current year

This one, using circular reference, works for me

 //a test-object with circular reference :
 var n1 = {   id:0,   text:"aaaaa",   parent:undefined} 
 var n2 = {  id:1,   text:"zzzzz",   parent:undefined } 
 var o = { arr:[n1,n2],   parent:undefined } 
 n1.parent = n2.parent = o;
 var obj = {   a:1,   b:2,   o:o }
 o.parent = obj;

 function deepClone(o,output){ 

     if(!output) output = {};  
     if(o.______clone) return o.______clone;
     o.______clone = output.______clone = output;

   for(var z in o){

     var obj = o[z];
     if(typeof(obj) == "object") output[z] = deepClone(obj)
     else output[z] = obj; 
    }

   return output;
}

console.log(deepClone(obj));

For a single result:

if (reader.Read())
{
    Response.Write(reader[0].ToString());
    Response.Write(reader[1].ToString());
}

For multiple results:

while (reader.Read())
{
    Response.Write(reader[0].ToString());
    Response.Write(reader[1].ToString());
}

In my opinion, the laziest solution (especially if you don't rely on latest bleeding edge C/C++ features, or latest compiler features) wasn't mentioned yet, so here it is:

Just build on the system with the oldest GLIBC you still want to support.

This is actually pretty easy to do nowadays with technologies like chroot, or KVM/Virtualbox, or docker, even if you don't really want to use such an old distro directly on any pc. In detail, to make a maximum portable binary of your software I recommend following these steps:

1. Just pick your poison of sandbox/virtualization/... whatever, and use it to get yourself a virtual older Ubuntu LTS and compile with the gcc/g++ it has in there by default. That automatically limits your GLIBC to the one available in that environment.

2. Avoid depending on external libs outside of foundational ones: like, you should dynamically link ground-level system stuff like glibc, libGL, libxcb/X11/wayland things, libasound/libpulseaudio, possibly GTK+ if you use that, but otherwise preferrably statically link external libs/ship them along if you can. Especially mostly self-contained libs like image loaders, multimedia decoders, etc can cause less breakage on other distros (breakage can be caused e.g. if only present somewhere in a different major version) if you statically ship them.

With that approach you get an old-GLIBC-compatible binary without any manual symbol tweaks, without doing a fully static binary (that may break for more complex programs because glibc hates that, and which may cause licensing issues for you), and without setting up any custom toolchain, any custom glibc copy, or whatever.

One other thing. You may need to specify the -L option as well - eg

-Wl,-rpath,/path/to/foo -L/path/to/foo -lbaz

or you may end up with an error like

ld: cannot find -lbaz

The extensions methods also provide a ToDictionary extension. It is fairly simple to use, the general usage is passing a lambda selector for the key and getting the object as the value, but you can pass a lambda selector for both key and value.

class SomeObject
{
    public int ID { get; set; }
    public string Name { get; set; }
}

SomeObject[] objects = new SomeObject[]
{
    new SomeObject { ID = 1, Name = "Hello" },
    new SomeObject { ID = 2, Name = "World" }
};

Dictionary<int, string> objectDictionary = objects.ToDictionary(o => o.ID, o => o.Name);

Then objectDictionary[1] Would contain the value "Hello"

The answer from Joey was not working for me. After executing

  echo ^<?xml version="1.0" encoding="utf-8" ?^> > myfile.xml

I got this error bash: syntax error near unexpected token `>'

This solution worked for me:

 echo "<?xml version=\"1.0\" encoding=\"utf-8\">" > myfile.txt

See also http://www.robvanderwoude.com/escapechars.php

This returns all xml-files recursively :

var allFiles = Directory.GetFiles(path, "*.xml", SearchOption.AllDirectories);

SELECT IF('database_name' IN(SELECT SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA), 1, 0) AS found;

import os
print os.name

This gives you the essential information you will usually need. To distinguish between, say, different editions of Windows, you will have to use a platform-specific method.

In simple word "you can't do it through simple setListAdapter" . you must used custom listview for freely changes in text color or in any other views

for Custom Listview you can go with this link

This worked fine for me (C#):

byte[] iconBytes = null;
using (var dbConnection = new SQLiteConnection(DataSource))
{
    dbConnection.Open();
    using (var transaction = dbConnection.BeginTransaction())
    {
        using (var command = new SQLiteCommand(dbConnection))
        {
            command.CommandText = "SELECT icon FROM my_table";

            using (var reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    if (reader["icon"] != null && !Convert.IsDBNull(reader["icon"]))
                    {
                        iconBytes = (byte[]) reader["icon"];
                    }
                }
            }
        }
        transaction.Commit();
    }
}

No need for chunking. Just cast to a byte array.

Here is a solution that will automatically convert to tabs whenever you open a file.

Create this file: .../Packages/User/on_file_load.py:

import sublime
import sublime_plugin

class OnFileLoadEventListener(sublime_plugin.EventListener):

    def on_load_async(self, view):
        view.run_command("unexpand_tabs")

NOTE. It causes the file to be in an unsaved state after opening it, even if no actual space-to-tab conversion took place... maybe some can help with a fix for that...

Using phpMyAdmin (or whatever you prefer), I just created a database called "forge" and re-ran the php artisan migrate command and it all worked.

If all fails, simply put the DLL in the windows\system32 folder . The compiler will find it. Specify the DLL to load from with: DllImport("user32.dll"..., set EntryPoint = "my_unmanaged_function" to import your desired unmanaged function to your C# app:

 using System;
using System.Runtime.InteropServices;

class Example
{
   // Use DllImport to import the Win32 MessageBox function.

   [DllImport ("user32.dll", CharSet = CharSet.Auto)]
   public static extern int MessageBox 
      (IntPtr hWnd, String text, String caption, uint type);

   static void Main()
   {
      // Call the MessageBox function using platform invoke.
      MessageBox (new IntPtr(0), "Hello, World!", "Hello Dialog", 0);    
   }
}

Source and even more DllImport examples : http://msdn.microsoft.com/en-us/library/aa288468(v=vs.71).aspx

<?php

$var1 = "Line 1 info blah blah <br /> Line 2 info blah blah";
$var1 = str_replace("<br />", "\n", $var1);

?>

<textarea><?php echo $var1; ?></textarea>

You should apply a "clearfix" to clear the parent element. Next thing, the h4 for the header title, extend all the way across the header, so after you apply clearfix, it will push down the child element causing the header div to have a larger height.

Here is a fix, just replace it with your code.

  <div class="panel-heading clearfix">
     <b>Panel header</b>
       <div class="btn-group pull-right">
        <a href="#" class="btn btn-default btn-sm">## Lock</a>
        <a href="#" class="btn btn-default btn-sm">## Delete</a>
        <a href="#" class="btn btn-default btn-sm">## Move</a>
      </div>
   </div>

Editted on 12/22/2015 - added .clearfix to heading div

Be sure to install lodash in the required folder. This is probably your C:\gwsk directory.

If that folder has a package.json file, it is also best to add --save behind the install command.

$ npm install lodash --save

The package.json file holds information about the project, but to keep it simple, it holds your project dependencies.

The save command will add the installed module to the project dependencies.

If the package.json file exists, and if it contains the lodash dependency you could try to remove the node_modules folder and run following command:

$ npm cache clean    
$ npm install

The first command will clean the npm cache. (just to be sure) The second command will install all (missing) dependencies of the project.

Hope this helps you understand the node package manager a little bit more.

You can pass a regex into Javascript's split operator. For example:

"1,2 3".split(/,| /) 
["1", "2", "3"]

Or, if you want to allow multiple separators together to act as one only:

"1, 2, , 3".split(/(?:,| )+/) 
["1", "2", "3"]

(You have to use the non-capturing (?:) parens because otherwise it gets spliced back into the result. Or you can be smart like Aaron and use a character class.)

(Examples tested in Safari + FF)

I had this problem and solved it by this way... I had a app in my pc that used adb... I tried to disable it but still my android studio's adb had problem after unistall that application and problem solved.

I'd just like to add to Jon's example. To get a reference to your own assembly, you can use:

Assembly myAssembly = Assembly.GetExecutingAssembly();

System.Reflection namespace.

If you want to examine an assembly that you have no reference to, you can use either of these:

Assembly assembly = Assembly.ReflectionOnlyLoad(fullAssemblyName);
Assembly assembly = Assembly.ReflectionOnlyLoadFrom(fileName);

If you intend to instantiate your type once you've found it:

Assembly assembly = Assembly.Load(fullAssemblyName);
Assembly assembly = Assembly.LoadFrom(fileName);

See the Assembly class documentation for more information.

Once you have the reference to the Assembly object, you can use assembly.GetTypes() like Jon already demonstrated.

The trick is to force the inner query return only one record by adding an aggregate function (I have used max() here). This will work perfectly as far as the query is concerned, but, honestly, OP should investigate why the inner query is returning multiple records by examining the data. Are these multiple records really relevant business wise?

If you know that your Properties object only contains <String, String> entries, you can resort to a raw type:

Properties properties = new Properties();
Map<String, String> map = new HashMap<String, String>((Map) properties);

I am using spyder 3.3.1 - windows 7 - python 3.6 although flush may not be needed. based on this posting - https://github.com/spyder-ide/spyder/issues/3437

   #works in spyder ipython console - \r at start of string , end=""
import time
import sys
    for i in range(20):
        time.sleep(0.5)
        print(f"\rnumber{i}",end="")
        sys.stdout.flush()

In case someone uses ZSH, all steps are the same, except a few things:

1. Locate file .zshrc
2. Add the following line at the bottom export PATH=~/.composer/vendor/bin:$PATH
3. source ~/.zshrc

Then try valet, if asks for password, then everything is ok.

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# HTTP POST variables
request.POST['section'] # => [39]
request.POST['MAINS'] # => [137]

# HTTP GET variables
request.GET['section'] # => [39]
request.GET['MAINS'] # => [137]

# HTTP POST and HTTP GET variables (Deprecated since Django 1.7)
request.REQUEST['section'] # => [39]
request.REQUEST['MAINS'] # => [137]

One of my websites involves a div whose size is variable and you won't know it ahead of time. it is an outer div with 2 nested divs, the outer div is the same width as the first nested div, which is the content, and the second nested div right below the content is the caption, which must be centered. Because the width is not known, I use jQuery to adjust accordingly.

so my html is this

<div id='outer-container'>
<div id='inner-container'></div>
<div id='captions'></div>
</div>

and then I center the captions in jQuery like this

captionWidth=$("#captions").css("width");
outerWidth=$("#outer-container").css("width");
marginIndent=(outerWidth-captionWidth)/2;
$("#captions").css("margin","0px "+marginIndent+"px");

On OS X, it's necessary to make sure Sandbox capabilities are set-up properly in order to use WKWebView.

This link made this clear to me: https://forums.developer.apple.com/thread/92265

Sharing hoping that it will help someone.

Select the Project File in the Navigator, select Capabilities, then make sure that:
* App Sandbox is OFF,
OR
* App Sandbox is ON AND Outgoing Connections (Client) is checked.

This is exactly what you want:

HTML

<div class="table">

    <div class="cell">
        <p>Text</p>
        <p>Text</p>
        <p>Text</p>
        <p>Text</p>
        <p>Text</p>
        <p>Text</p>
        <p>Text</p>
        <p>Text</p>
    </div>
    <div class="cell">
        <div class="container">Text</div>
    </div>
</div>

CSS

.table {
    display: table;
    height:auto;
}

.cell {
    border: 2px solid black; 
    display:table-cell;
    vertical-align:top;
}

.container {
    height: 100%;
    overflow:auto;
    border: 2px solid green;
    -moz-box-sizing: border-box;
}
